If there are few or no branching veins between the access and stenosis, thrombosis could occur Etiology The most common etiology is venous stenosis caused by a history of vessel wall trauma by centrally-inserted venous devices such as tunneled and non-tunneled dialysis catheters, central lines, pacemakers, or defibrillator. In a study performed at a large academic medical center1, new hemodynamically significant central venous stenosis was associated with the duration of catheter dependence (26% in patients with CVCs for more than 6 months, versus 11% in patients with CVCs for less than 6 months). PICC lines can directly damage cephalic and basilic veins Venous stenosis can often go undetected until AV access creation occurs Patient Presentation Symptoms of venous insufficiency will be present– most commonly regional edema, in the area of venous stenosis. If there are patent venous branches between the AV anastomosis and the stenotic area, swelling can occur throughout the arm. Pigmentation, induration, dermatosclerosis, and ulceration may also be observed. An extensive collateral network of veins may be visible throughout anterior chest, shoulder, or flank SVC obstruction can result in swelling of the head, neck and shoulders, as well as a feeling of head and neck fullness, airway compromise, and visual problems Normal palpable thrill can be replaced by a strong pulse Dialysis can be complicated by difficulty with needle access, recirculation syndrome, and arm swelling after dialysis sessions. Workup Central vein thrombosis can be hard to detect on ultrasound because clavicle and sternum can block transmission Venography is essential to determine the presence and severity of venous stenosis or occlusion. Prevention The ideal scenario is to avoid central dialysis catheters completely, and this involves evaluating CKD patients and placing AVF or AVG before the need for dialysis arises. If a patient presents placement of an AVF/AVG, it is important to perform venography if a patient has a history of a central venous catheter or clinical signs of venous hypertension. A history of SVC obstruction from any cause can preclude permanent AV access creation in both upper extremities Treatment Endovascular approaches to venous outflow stenosis can be first-line treatment options, due to their minimal risk. They can also be performed at the same time as a diagnostic venogram. Angioplasty alone or with stenting are the endovascular options. In a study by Bakken et al2 that compared primary high-pressure balloon angioplasty versus stenting, primary patency was equivalent between groups, with 30-day rates of 76% for both groups and 12-month rates of 29% for angioplasty and 21% for stenting. Assisted primary patency was also equivalent with a 30-day patency rate of 81% and 12-month rate of 73% for the angioplasty group, 84% at 30 days, and 46% at 12 months for the stenting group. This study, along with others, shows that the major downside of endovascular interventions, whether angioplasty or stenting, often require repeat intervention and have poor long-term patency. For subclavian vein stenosis, angioplasty alone is appropriate due to its anatomical location that can put a stent at risk for extrinsic compression from the first rib and clavicle. Surgical bypass can be performed Possible bypasses include axillary-axillary, axillary-jugular, axillary-right atrial, and axillary-femoral. In these bypasses, the preferred conduits are autogenous saphenous or femoral veins. In cases where the proximal subclavian vein is obstructed, a jugular vein turndown can be performed. In this procedure the distal jugular vein is transected, sewed end-to-side at the distal subclavian vein, effectively acting as a bypass route for that obstructed segment. The Hemoaccess Reliable Outflow (HeRO) Vascular Access Device can be used as a hybrid approach, combining endovascular and open surgical techniques to bypass a central venous occlusion and provide a reliable outflow for dialysis. This device has a PTFE inflow limb that is sewn end-to-side onto the brachial artery. This limb is tunneled subcutaneously and connected to a silicone-coated nitinol outflow catheter that is inserted into a central vein and tracked directly into the right atrium. This effectively bypasses central venous stenoses. In the largest study to date on HeRO access grafts placed in 167 patients,3 HeRO primary and secondary patency was 48.8% and 90.8%, respectively, at 12 months. Interventions to maintain or re-establish patency were required in 71.3% of patients resulting in an intervention rate of 1.5/year. Access-related infections were reported in 4.3% patients. The authors concluded that HeRO device had performed comparably to standard AVGs and had proven superior to tunneled dialysis catheters in terms of patency, intervention, and infection rates. If no treatment options for venous hypertension or outflow obstruction are available, an alternate AV access site can be created, either in the contralateral arm if the SVC is uninvolved, or through placement of femoral AV access or a peritoneal dialysis catheter. Bleeding Access Site Etiology and Risk Factors Bleeding can be caused by high venous pressure after dialysis, pseudoaneurysm rupture, or trauma. Patients with end stage renal disease (ESRD) have a baseline elevated risk of bleeding due to uremia-induced platelet dysfunction and use of systemic anticoagulation within the hemodialysis circuit. Additional risk factors include dialysis through an AV graft, hypertension, longer duration of access use, and compromised integrity of the vascular access due to complications (clotting, infection) or invasive procedures. Dual antiplatelet therapy is also associated with overall bleeding events in ESRD patients. Dialysis patients could be on antiplatelet therapy for management of comorbid cardiovascular risk and/or patency of AV graft Patients with bleeding fistulas often present from their dialysis unit when standard digital pressure at the cannulation site fails to stop the bleeding. This is a very serious condition since most mature fistulas have high blood flow and the patients are at risk for hemorrhagic shock and death. Initial Management The first step of management is to obtain hemostasis. Elevate the limb above the level of the heart and apply firm and directed pressure at the site of bleeding using gauze for at least 30-40 minutes Milosevic et al4 reviewed non-operative management of bleeding fistulas and grafts and found that compared to standard dressings, the use of specialized hemostatic dressings decreased bleeding time at arterial and venous cannulation sites. These hemostatic materials included the IRIS compression bandage and cellulose-based, chitosan-based, poly-N-acetyl glucosamine-based, and thrombin-soaked dressings. There has been a “bottlecap method” described where the hollow side of a bottlecap is pressed on top of the puncture site. Maintaining pressure on the cap will cause the cap to fill with blood and clot, which tamponades the bleeding. The provider can also place a shallow figure-of-8 or purse string stitch just below the skin surface to aid in hemostasis. It is important to avoid placing the suture too deep as this can cause inadvertent fistula ligation. During this process, an assistant applies pressure just proximal and distal to the bleeding site to stop blood flow so the sutures can be placed. If these methods fail to achieve hemostasis, apply a tourniquet proximal to the fistula and tighten it until bleeding stops and the radial pulse is lost. This signifies complete occlusion of arterial inflow to the fistula. Tourniquet use should be limited to 3 hours or less, since limb ischemia beyond this timepoint is associated with permanent neuromuscular damage. Regardless of the method used for initial hemostasis, the patient is at risk for repeat hemorrhage, hematoma formation, vessel stenosis, and thrombosis. They should be evaluated by a vascular surgeon as soon as possible. Definitive Management Definitive management depends on etiology of each case, and there are a variety of interventions that can be pursued (i.e. aneurysmorrhaphy for aneurysmal bleeding) If skin erosion over the conduit is present, it should be assumed that the AV access is infected and emergency intervention should be pursued. A jump graft can be placed through with healthy tissue. A covered stent could be introduced through a separate percutaneous puncture site Finally, coagulopathy can be addressed by administering cryoprecipitate, DDAVP, erythropoietin, estrogen, tranexamic acid. Aneurysms and Pseudoaneurysms Definition and Etiology Aneurysms involve all three layers of the vessel wall and they develop due to hemodynamic changes causing remodeling of the vein wall in an AV fistula. This is necessary for vein maturation, but becomes problematic if the post-anastomotic vein continues to dilate and becomes aneurysmal. Aneurysms can also occur at anastomosis sites due to technical aspects of the surgery. Pseudoaneurysms only involve some layers of the vessel wall caused by repeated puncture for hemodialysis. Both aneurysms and pseudoaneurysms can enlarge due to venous outflow stenosis causing increased intraluminal pressures. Both true aneurysms and pseudoaneurysms can lead to overlying skin erosion and subsequent hemorrhage, pain, AV access dysfunction, and cannulation difficulties. Dialysis cannulation should be avoided at the aneurysmal sites to prevent bleeding complications. Diagnosis They can be diagnosed on ultrasound, which also provide information on flow rates, presence inflow/outflow/stenoses, and vessel diameters. Indications for Treatment Treatment is indicated for aneurysms that are rapidly expanding or ulcerating through the skin surface. These are at high risk for rupture and hemorrhage, which is life-threatening. Treatment is also indicated when the aneurysm occurs at the anastomotic site of the AV fistula, the patient has a cosmetic concern, cannulation becomes difficult, there is concern for infection, or the patient has high-output heart failure that could be exacerbated by high flow through the fistula. Treatment is not indicated in asymptomatic aneurysms, regardless of their size. True aneurysms and pseudoaneurysms are not prone to spontaneous rupture. Treatment Options Aneurysmorrhaphy is the most common treatment. It involves the resection of the aneurysmal vein wall to restore a normal diameter and removal of excess skin. Anastomosis is performed along the lateral wall to prevent issues with cannulation along the suture line. Aneurysm resection with interposition grafting is also possible. If multiple aneurysmal segments require treatment, staging their repairs can allow for continuation of dialysis without needing to place a temporary dialysis catheter. AV access ligation is an appropriate alternative to AV access salvage in certain situations but usually requires excision of the aneurysm/pseudoaneurysm due to the potential to develop thrombophlebitis and the cosmetic appearance of the thrombosed segment. If there is concern for an infected pseudoaneurysm or aneurysm, surgery should include removal of all infected material. References 1. Al-Balas A, Almehmi A, Varma R, Al-Balas H, Allon M.

Listen to The Automation Podcast from The Automation Blog: Read the transcript on The Automation Blog: (automatically generated) Shawn Tierney (host): Welcome back to the automation podcast. My name is Shawn from Insights, and I wanna thank you for tuning back in. Now in this episode, I had the pleasure of meeting up with Eugene Silva from Emerson to learn all about the industrial control and monitoring system that comes with their industrial dust collectors. Now I thought it was very interesting. I hope you do as well. But before we jump into this episode, I do wanna thank our members who made the video edition possible. So So when a vendor does a sponsor of the episode, the video becomes a member only perk, and that is just $5 a month to get started. So thank you members for making the video edition possible. With that, I also wanna thank our sponsor for this week’s show, the automationschool.com and the automationblog.com. I have an update later in the show what’s going on on both sites, and I hope you’ll, stick around and listen to that, towards the end of the show. But with that said, let’s go ahead and jump into this week’s episode of the automation podcast. It is my pleasure to welcome Emerson back on the show and Eugene on the show to talk about dust collector monitoring. You guys can see the slide if you’re watching dust collector monitoring and control solutions. I’m excited about this because this is a solution versus, like, a discrete product. So with that said, Eugene, would you please introduce yourself to our audience? Eugenio Silva (Emerson): Yes. Shawn, thank you very much for this opportunity. Hello, everyone. Here’s Eugenio Silva. I’m a product manager, intelligence automation within Emerson, the discrete automation part of Emerson. I’m glad today gonna share some, some of our understanding and learnings with the dust collector monitoring control solution. And, when I talk about that, Emerson is also involved in in others, types of solutions that, our purpose is to drive innovation that makes the world healthier, safer, smart, and more sustainable. And I’m also responsible for continuous emission monitoring, pest collectors is one, utility, energy and compressed air management solutions. So for today, I prepared something that, we go a little bit, into why this type of, test collector solution is important, from understand of our customers and industry point of view. We’re going to look into the fundamentals of a dust collection, from the particle sensors to the dust collector systems, and then dive in into the dust collector solution where I’m going to provide you, some features, also explanation why they are there, and how this kind of capabilities deliver value to our end users and customers, and, hopefully, to have time as well to have a short, recorded demo that, brings us, full scope how the operators look into into that solution when they they use it. Shawn Tierney (host): But before we jump in, I wanna thank the automationschool.com for sponsoring this episode of the show. That’s where you’ll find all of my online courses on Allen Bradley and Siemens PLCs and HMIs. So if you know anybody who needs to get up to speed on those products, please mention the automationschool.com to them. And now let’s jump back into the show. Eugenio Silva (Emerson): In terms of key applications, industries use cases, dust collector is essential for many industries that produce dust, produce any kind of a pounder, any kind of a fume, and typically air pollution control, boundary processing, handling, industrial dust, fume ventilation are covered by one or another way by dust collectors. And, the industries that I put in both, these are the the dirty ones in the sense that they produce a lot of, particle, either in terms of gases or dust. Therefore, the regulations that are in these industries are quite strong. So cement, metals, chemical plus, carbon, black and toner, like lithium battery assembly, disassembly, metal foundry. And what is interesting is the either you produce a waste that you have to manage it properly, can be also recycled, for example, in the industries like plastics in food or wood. All the collected dust that you have, you can also reuse and sometimes recycle. But why? Why this is important? Why is it important to extract dust from these industries? Let’s start on the right side because this is what the the customer is looking for. Because the cost of our pollution, the hazards, this this safe safety accidents that can be caused by this kind of harmful airborne and particles and forms are so substantial, then of course, it’s very much regulated in all these industries. And if you calculate the costs on the public health, Sometimes big accidents in plants where even big fires or hazards to people operating the plant. We talk about billions per year, the cost of that. And one of the consequences of having such issues is that when the dust extraction system is not working properly or you have really a downtime. For example, I’m going to explain that this really depends on components that are very, they use so often that they wear down, like filters, like post files. And each time that we have a downtime is not the cost of the dust collector downtime that’s important. It’s the overall downtime costs that imposes to the operation of the plant because in order to be conformist, they have to stop operating until they fix the issue. And these downtimes, of course, arise in many ways in different aspects. How complex is this dust collector. But I’m I’m going to give you, some insights that, if a dust collector system does not have any solution to monitoring real time or control, the efficiency. Basically, the personnel is managing these assets without any sight, and everything can go wrong. That’s why the TCO and the maintenance aspects are quite important. Because if you’re not aware where is the problem, when you have to plan and this becomes a firefighting or reactive mode, then your costs are going to be quite high. And when you talk about the TCO, it’s about the cost of the equipment, the acquisition, the cost of operation, meaning not only the personnel, but in this case, we use a lot of compressed air. I’m going to explain why. The maintenance costs, as we explained, and the disposal costs. Disposal means, the filter bags that must be replaced and and changed, but also the the dust, the fume, all the elements that must be, properly managed and recycling sometimes. So this is the aspects why it’s important. Now let’s turn us about, the benefits and savings. So if you use the dust collector solutions, of any kind that can monitor in real time all the aspects, of the operation of a dust collector system and, also contributes turning maintenance from reactive to preventative and maybe predictive, then the best thing that you can do is to avoid huge penalties. As you can see on this graph, every decade, let’s say, the fines are getting steeper. And the reason for that is because of the the damage and the result of a big, like, say, issue on the plant regarding to this dust part is is quite heavy. So, therefore, we talk about 100 k’s or even plus in some industries like primary metal and chemical, where one single incident, it’s about a 100 k in average or more. And then, of course, to avoid that and to be completely compliance, you have to operate that systems, in many cases, 24 by seven. And, therefore, any way possible to reduce downtime and, as a plus, reduce the energy costs because for compressed air, you have to use electricity, then, it pays off because you’re going to be full time compliant. And the other thing is if you do properly, monitor and control your dust collector system, you also increase the filtration efficiency. So that means you are far from the high levels, where after that threshold, you would be penalized. You can operate under, conformist, under compliance, but can also expand the equipment life. For example, the life bags, the post valves, you don’t have it to replace as often, which is the case if you don’t do any real time monitoring diagnostics. On the left side, the way that we talk about improving maintenance is the total cost. When we talk about the filter life, at least one unit of a filter, It’s about 18 k, US dollars. And you see that, the tip of a iceberg is just the purchase price. The dust collector system, like, of course, has an acquisition cost. But below that, as a total cost of ownership, you have the energy that you expand utilizing the systems. You have the filter bags. You have to keep parts in your inventory. You have to dispose of that. And, of course, you have the downtime costs and also the labors labor costs. Now I’m going to just to give, a chance to say, okay. Tell me how a dust collector system works. Shawn Tierney (host): Before we get to that, we gotta pay the bills. So I wanna tell you about our sponsor, the automationschool.com. It’s actually the next room over. We have a huge training room. We have, some of the most unique products you’ll be able to work on. You know, I know everybody has a bunch of CompactLogix or s seven twelve hundreds or 15 hundreds and, you know, VFDs and HMIs. But some of the products we have here, you’re not gonna find in anybody else’s training room, not even the factory’s training room because we cover all different products. Right? So if you’re coming over to do training with us, you can actually learn Siemens and Allen Bradley at the same time. You can learn how to get Siemens and Allen Bradley to talk together. You guys know I’ve covered that on the show, but you could do it hands on. And some of the other things is like working with third party products. Right? So, you know, if you go to a vendor’s course, they’re not gonna have third party products. But we have as you remember from the wall in my studio, we have all kinds of third party products. And I’m gonna be taking some more pictures of all the different labs we have, the equipment we use, with these third party products. So if you know anybody looking for training and we can do custom things too. So if you wanna start training at noontime or 01:00 because you’re gonna drive in three or four hours away, I was recently just at a, large vendor’s customer doing some training on their behalf. And, yeah, that was a long drive. So if you want your, students to show up in person at twelve or one and then train and then at the on the last day, leave around twelve or one, we can do that as well. I don’t care. We could actually run into the night if you wanted to go, do evenings. Or, again, some people don’t learn very well in the evenings, but in any case, because I own the company, we can do whatever you want. As long as we have the equipment and the time to put it together, we’ll do it for you. So I just wanted to make you aware of that. We also if you’re, just wanna come yourself, if you go to the automationschool.com forward slash live, you will see a place where you can preregister for an upcoming class. And when I get enough people to sign up, I’ll reach out to you and tell you what date is gonna be held. And by preregistering like that, you will save $50 off the $500 price. And if you’re already a student, you will save the price of your online course off of the in person course. So maybe you bought my $200 Siemens or CompactLogix, ControlLogix cost. They’re gonna get that off of that $500. Right? And if you don’t own the online cost, don’t worry about it. If you come here for in person training, at the end of your training, we’re gonna enroll you, in one of those online courses completely free of charge so you can continue your learning. And you don’t have to worry about trying to blitz all the content while you’re here because whether you’re here for a day or five, it doesn’t matter. Whatever you have left to learn, you’ll be able to do it after hours at home, and there’s no additional charge for that. So with that said, let’s get back into this week’s episode of the automation podcast. Eugenio Silva (Emerson): And these are going to be general principles and basics. In general, a dust collector system looks like this. It’s a unit where the air is pulled in at the bottom of the compartment, and this could be forced or not. And then the air gets out, on the top, the outlet, and the dust is collected on the outside of the bag. So if you see this, in this picture, we have one full bag in kind of light brown color with a specific fabric, could be porosis fabric, a PVC, or some even paper in some cases. And then the cleaner exceeds at the top. And the what happens is that the dust cake builds up on the bags, on the outside part of the bag. And, if you see the number one on top, in that particular, entry point, we have two pulse valves with, compressed air in order to shake a little bit these, post bags, filter bags, and then knocks down the dust out of these bags, and then they are collected by a hopper at the bottom. Okay? So that’s basically, in general, how it works the principle. It’s a bit more complicated. Here is just to show that in order to automate a dust collector system including the filter bags, we use, a combination of, electrical and pneumatic, components. And these are from post valves, the ones that continuously blow air into these pipes, the compressed air tanks that hold the right pressure and the right compressed air capacity in order to keep the filtration efficiency very high. Then you have the filter regulators that, you have to bring, the pressure of this line to higher enough, to to be efficient, but not so high to spend too much compressed air. Then you can use controllers, black boxes that are able to do a time based sequencing, but these are not so so much sometimes efficient because it doesn’t take into consideration all the diagnostics that you can get out of it. And then, basically, the very important element is this, particle sensor that is on the outside of the clean air because that is gonna be your canary in the mind. Right? It’s gonna be the one that indicates if the filter, system is efficient efficient and if the the job is done right. And then the other things. But let’s go back to a very interesting view. You remember this picture here that, you you’re looking at, a cross session of the dust collector. Now you could imagine how it looks like from the top. From the top, it looks like that. There is a compressed air tank, that covers, certain portion of the filters units. For example, it’s very common that a filter, complete filter unit, might have different compartments. And in each of these compartments, you have a series of filter bags. And then imagine that you provide short but very powerful pulses of compressed air that are periodically injected on top of this columns. And below, there’s a filter bag. So, therefore, they are going to to receive to expand a little bit, and the dust cake then, outside of of their surface follows. And by inertial forces, of course, this dust is accumulated at the bottom, which is, extracted into a hopper. Of course, now depending of the number of the filters per line, per roll, these pulse valves needs to pulse a little bit faster or not. And the interval time, if you just follow time based approach, could be three to six minutes. Now if you calculate the average filter units, you may have 12 of these filter bags. You can have about seven to 10 pulse valves per unit. It’s very common that, one large installation would have about, like, 500 pulse valves and four, six times more filters, install it. And imagine that if each of them having boost every three minutes, 24 by seven, during seven days a week. So can you imagine the amount of compressed air that can be spent? That’s why these pulses must be very short and powerful, in hundred milliseconds to avoid it also big waste. I think that, picture on the left side, just to simply say that, it’s a lot of, interesting things to to get the dust removal, but basically is a jet of compressed air on top, that shakes the filter. And then by gravity, the dust cake is removed. Shawn Tierney (host): It’s not just a filter. You know, I think main main people may just think, well, a dust collector is just this bag that catches all the dust. You’re actually, you know, you’re you you do have the bags, but, you’re using compressed air to sequentially, depends depending on how many you have, shake those bags in a sense by blowing air into them, to shake off the dust so it falls into the hopper. And so I can you can definitely see, like you were mentioning, if you have lots of these cylinders or these bags, then the sequencing has to be, you know, pretty pretty precise and and pretty, repeatable to make sure you’re you’re cleaning all of the bags off. And I’m I’m assuming too, you need to know when the hopper is full because everything stops working if if if the hopper gets, over full. So very interesting. I think your diagrams do a great job of explaining it as well. Eugenio Silva (Emerson): Yeah. If I play a little bit when I mention that, it’s a a little bit the reverse, way of our vacuum cleaner. Right? Because Yeah. We suck the the dust inside of the bags. Mhmm. And when the bags are completely full clogged, the suction, power, it’s far reduced. Right? So then you have to to empty our, let’s say, filter bags. Here is the although the all the dust is accumulated on the outside, the outer surface of the fabric, but the effect is the same. If there’s so much dust on the surface or out of the surface, then, the air that is shown here, the intake, the air, and then the filter simply stops. That’s why affects completely the efficiency of, that, unit. And the post jet cleaning is a way to unclog or to clean, the filters in order to bring them to the more efficient operation. Shawn Tierney (host): Yeah. Especially if you have lots of dust, you need an automatic way to continue to clean it and get it off of the filter and into the bin. So yeah. No. That makes a lot of sense. Eugenio Silva (Emerson): Yeah. In in other cases, although you talk about, dust, of course, it could be any kind of a pounder. Like, for example, in the foods and beverage industry, you don’t want this for example, let’s say, a dry milk production. You don’t want that dust to be floating around because it can bring contamination. But believe it or not, it can ignite fire sometimes. So that’s why it’s important to to get that completely eliminated. So this is the part that very people would say, okay, on the outlet where the the air should be cleaner, as you can see on the right side, that this, particle sensor is located at the outlet, clean air side. It has a very interesting the way it works is quite interesting. We use a we have a sensor in our portfolio called p 152 that, we take advantage of this triboelectric effect. Basically, this sensor, is coated with PTFE or a Teflon layer, so it’s completely electronic, electric isolated from from, of course, the media. And then when the dust starts touching, that probe, a DC charge is transferred. But because of this, sensor probe is completely isolated, we set the flow layer, the resolution and the electric charge is in the order of a peak ramp. So 10 minus 12. And that the resolution is about point five picoamp. So, therefore, if you’re touching the particles, depends of their size, They are going to generate more or less electricity that’s going to be transferred. And the ones that are just surround, they are not touching. For example, imagine that this, duct air exhausting pipe is quite big. A bit half meter, maximum one meter around that sensor, the particle also generates, induced charge in AC. And by measuring that, we have an idea about how clean is, of course, there that’s getting out. But it’s a bit more tricky than you can imagine because it looks like this. Shawn Tierney (host): Hey, everyone. I hope you enjoy this week’s show. I know I really enjoyed it. And, of course, I wanna thank our members for making the video edition possible. So this vendor did not sponsor this episode. So the video edition is available for members, and there’s some great graphics in their presentation you guys may wanna check out. Now with that said, we do have some really exciting podcast episodes coming up. I’m sitting down with Inductive. I’m sitting down with Software Toolbox. I’m sitting down with Siemens and a bunch of other vendors. So we have plenty of new podcasts coming up in the coming weeks this summer. And I also wanted to give you an update of what’s going on over at the automation blog. We’ve had some new articles come out. Brandon Cooper, one of our freelancers, wrote a great article about emulating Allen Bradley e threes. We had a vendor, actually, submit an article and sponsor the site to submit an article about what makes a good automated palletizer. We also had an update about the automation museum. That’s a fundraiser we’re running. We’re trying to open a automation museum. I got a lot of legacy stuff I’d like to donate to it, and I’d love to have it so you can come in and actually walk through, not just see the stuff, but actually learn on it. Right? So maybe you have some old stuff in your plant. You come out to the automation museum, and you can learn how to use it. With that said, we’re also looking at possibly doing a podcast for automation museum to drive awareness of legacy automation. So any of you out there interested in that, contact me directly. And, you can do so over at the automationblog.com. Just click on the contact button. And, we also have an article two articles from Brandon Cooper about things he learned as he transitioned from working in a plant to traveling around and visiting other plants to help them with their processes and automation. So check those articles out over at the automation blog. And finally, over at the automation school, you know, we have the new factor IO courses. We also have I just added a new lesson to the logics version of that course. Somebody wanted to try to use bit shifts instead of counters, so I added a lesson on that. Plus, I’m now starting to update all of the courses, including the brand new ones I’m working on. So you’re gonna see a brand new start here lesson later in the week, and I’m working on some cool emulation, lateral logic for my PLC courses that if you don’t have any push buttons or limit switches, you can actually use this code I’m gonna give you for free to simulate the widget machine that I use as kind of the basis for my teaching. So in any case, check that out if you’re in one of my PLC courses over at the automationschool.com. And with that said, you know, I’m very thankful for all the vendors who come on, especially those who sponsor the episodes so I don’t have to do these commercials. I’m not a big commercial guy, but I do wanna thank you for hanging in there and listening through this update. And now we’ll get right back into this episode of the automation podcast. Eugenio Silva (Emerson): Every time you get, use the jet boost with the boost valves on top of the filter bags, it creates a peak. So that means the cleaning cycles that are happening in a duration of, just a 100 milliseconds. That’s why they are very, very thin. And they happening every two, three minutes, per roll. They have to they have in nature a little bit of noise because imagine that every time that, you clean, more dust gets into inside of the the filter back. So that means it’s like when you clean your vacuum cleaner, immediately when you turn on that, some of this dust is gonna get inside immediately, and that’s the peak. But now imagine that, you have a rupture in the filter or you have a big role because, unfortunately, these the things are wear out. And then these peaks starts getting higher and higher. So, therefore, what we do when we, put that solution in place for a little time, let’s say, couple of days, we needed to kind of, set up, these thresholds. We need to figure out the level of noise that could be because depends very much the capacity, the types of, of a test. But once you do that, in our solution, we set the thresholds like alarming, a warning alarm, which means that after that point, the maintenance crew, starts looking at, that could be a early indication that a filter bag is not okay until the maximum point that avoids any any nonconformist, issue, which is already a rupture. You really pass the time where this filter, must be replaced. Shawn Tierney (host): So we’re looking at this chart for those who are listening. And the particle sensor, you know, it’s measuring the particles as air flows normally. But during the pulse, right, we’re forcing a lot of air back in, back down. So we’re getting a lot more, you know, than the average air would have x amount of particles. But if we’re forcing a bunch of it back in, we’re gonna see a lot more particles per, let’s say, hundred millisecond pulse. Right? So we do expect a peak when we when we pulse it because we’re just forcing a lot of get back go into the reverse direction. So we can we catch the bag loose. But what you’re saying here on this chart, I find so in so much interesting. So you can quantify, like, the expected increase in, in dust that you’re gonna sense with the sensor when you go in the reverse, when you pulse pulse, blow the ear downwards to, to shake the bag free. But you’re saying if that if that extra increased amount of detected dust is either too high, above normal, or too low below normal, then that tells you that you you could either have a clogged bag or you could have a burst bag. Is that am I understanding that correctly? Eugenio Silva (Emerson): Yes. Is this correct? And then the interesting thing is that as soon as you’re getting closer to replace a filter back, this baseline starts raising a bit with a kind of, how can I say, there is a drift? Why? Exactly what you said. A filter is completely clogged. It’s not yet any rupture, but is the efficiency of the cleaning is not so okay. So therefore, this slightly changes needs to be analyzed. Why I’m showing row one to row 10? Exactly in the picture, if you remember, a compartment filter with several, let’s say, filter bags, they are under the row. So under the row one, you may have 10 filter bags, row two, row three, and so on. So that means you are able to indicate which row is the problem, but it might be that you still need to check further which of the filters in that particular row have the problems. The more quick this peak happens, more number of, filter bags can have a problem. Shawn Tierney (host): Mhmm. Eugenio Silva (Emerson): Okay? Shawn Tierney (host): So you have one sensor on the exhaust, and you’re sequencing through, you know, blowing out or shaking out, you know, pulsing each of the rows. So that’s why we see, you know, one reading across the, you know, across the horizontal, and we see your row, row one, row two, row three, row four, each of them with discrete values or pulses. And like you just said, if you have multiple issues on a row, then you’re going to see, you know, a higher or lower peak depending on what the issue is. I’m with you. Eugenio Silva (Emerson): Yes. That’s why I’m going to show the other diagnostic capabilities that we needed to associate with this, particle sensor. And just to remember that, this particle sensor, we simply use one unit on the outlet part. That’s why I needed to make the sequence in serialization of the post because then I need to to synchronize with the post jets of every role. Shawn Tierney (host): Mhmm. Eugenio Silva (Emerson): No? Row by row. Shawn Tierney (host): And I think too, if you tried to do them all at once, the the you would need a lot higher pressure. So it it kinda makes sense to do it row by row because it reduces your maximum pressure required. Eugenio Silva (Emerson): Yeah. In this practical sense, we’re not be able to Shawn Tierney (host): Differentiate. Eugenio Silva (Emerson): Identify which of the roles, would be the problem. That’s why we kind of still have to do that. But now let’s give in a solution overview, and I think that, some of the key capabilities and features are going to highlight even more, the other, diagnostic capabilities that we are able to to provide in order to identify correctly and early as possible such issues. So this is a typical dust collector system. And if you look at around, if this dust collector system is just, let’s say, automated with nomadic electric components and they don’t have real time monitoring, you’re not really know the emission level. If it also this is not real time monitoring with some diagnostics, then you are not able to identify when this particle sensor, for example, is completely taken by, the dust because the humidity entrance in that, in that pipe, or it might be that, it’s so dirty, your dust that, is already ingrained so much on the probe. Mhmm. So that’s why the poor, reliability or the low level sensitivity of that could be affected. And if you were not monitoring, these signals that I showed the these peaks synchronized with the post valve jets Mhmm. You don’t have any early warning. Okay? The post valves basically are coils. They are solenoid coils Shawn Tierney (host): Mhmm. Eugenio Silva (Emerson): With tag diaphragms that open and close at the speed of a hundred milliseconds. The point is that their life time is about a couple of millions of cycles. Mhmm. But imagine, in some cases, one, two years is already enough to to have end end of life. So a fault valve, has to be connected to a control system because you need to know if this is a short circuit or if the diaphragm is completely open. And you can only do that if every time that you cycle the valve, you also, check that. For example, the power that, you drive the coil gives you a feeling if that is a coil that is already gone. Okay? Now let’s talk about the compressed air. Right? If you have a a filter that is open, there’s a rupture. If you have, a diaphragm that’s completely gone open, you start consuming higher and higher the compressed air. The point is this is continuously increasing. You can just imagine that this is normal. But if you go into average and look at this in a historical way, you’re gonna see that this trend is caused because of the broken post valves, for example. So that’s why it’s also important aspect of the automation solution is to minimize the usage of the compressed air is to have a clearly operating under a baseline that is normal. The filter bags, independent of the materials, because if you talk about life sciences, foods, chemical, or metal, they have a different materials. They have a different, where else, lifetime span. The point is the costs might be the filter itself is not so expensive. But going up there, exchange stopping, moving things around, getting the dust out before you change, putting all the personal protection equipment may take hours. So, therefore, that is the cost of that. And if you’re not able to prevent or even have an early warning when that is going to occur, is gonna be a reactive, maintenance issue. Right? So that’s why just convincing that, it’s worth looking into different aspects. And that’s why, on the left side, when we talk about solutions, we talk about, the connectivity part that, we have to work with devices that are hard or four to 20 milliamps. Some of devices are modbus to CP. Newer actuators in post faults could be mu m q t t or even OPC UA. That’s the the PLC part that, we have. And we can work with pneumatic systems, for example, that they turn at AP, PROFINET, or any other, standards. Then, of course, we have the IOs, that, we have to look at to control the post jet systems, but also to monitor the differential pressures, to measure the compressed here in some cases, until the parts where at the top, we put HMI SCADA software platform that, we pre engineered, in order to to make it simpler the development, of that solution by our OABS or many cases directly to our end users. And all in the right are the elements that we offer in our portfolio. Some cases, OEMs of a dust collector systems just to take from us, and they might be that they have their own solution as well. Shawn Tierney (host): So just for the audio audience, I know we’ve covered these products a lot, especially on the news show. But, I mean, I’m just wanna kinda go through a couple of these things. You got the ASCO product line. Right? So remote piloted valves and, you know, all of those, that category, you know, the, pulse valves. But we also got the Advantex, which we’ve talked about, like figure filter regulators and, different cylinders. Topworks, which I think we’re all familiar with, proximity sensors and whatnot. And, some of the other products you guys, Rosemount, differential pressure transmitters. We also see, we have, the PAC systems. In this case, you could have edge analytics, and so you may have one of the PAC systems, edge IPCs. And we even see the, down in the corner there, the Emerson PLC and IOs, which I think we’re all familiar with as well. So that kinda shows you how, you know, this solution, you know, they’re taking all these different products they have in their catalog and putting it together in one solution, which is, you know, you kinda need all this stuff. You know, basically understanding how it works. We just went through it. And so it’s interesting. I don’t think I’ve seen a slide yet from Emerson where they kinda include in one application all, if not all, many of their their, different product lines. And then, the the skate on the top, it looks like, just some beautiful screens and charts and and, you know, dials showing the current status. So, and and I I didn’t mean to interrupt you, Gino, but nonetheless say that, especially since the people listening, they’ll be familiar with all those trade names because we’ve covered those in the past. But, in any case, let me turn it back to you. Eugenio Silva (Emerson): No. No. It’s thanks for highlighting. And I I say that, when I introduce myself that I’m from the discrete automation part of Emerson. Mhmm. Because most of, people would know Emerson by the Rosemont, for example, pressure, Fisher valves, and then the, you know, the delta v, DCS. Right? This is the discrete automation part, and that’s why probably something new, for everybody here. Thank you very much. So when I look at that in a nutshell, we, of course, have to put the sensory devices, the PLC on top, the HMI scanner. And, basically, what we provide is real time monitoring of this particulate, emissions. We detect but also locate where the leak is by compartments in rows. You can see on the picture that, on the top of this HMI screen, we have a filter unit with three compartments, compartment one, two, three. And each compartment has these rows on top, which is the number of rows, then the more a number of filter bags that, within each, compartment. So, therefore, just locating which compartment and which row, you have a problem, I can tell you it saves half day of the people, in the maintenance. We also optimize the push at cleaning. It’s an, patent based algorithm that is completely adaptive, and works not just with the post valves, but, we put, head pressure sensors. And this fluctuation and the differential pressure that we measure from the outlet and inlet allows us, of course, to, increase or decrease the frequency of these push heads, which allows not only to be more efficient, but also minimize compressed air. And then finally, when you talk about solidoids involved diaphragms, these ones we can indicate one by one where they have problems. So, therefore, if you look at down to the other HMI screen, there are two rows on top. The one that is a solenoid, the one that is a diaphragm, and these vertical bars are the filter bag health. If they are getting closer to red with the high levels, meaning that, their life span is already gone. And if you have, light indicators on the solenoid, the diaphragm depend of the color might be that you have a short circuit fail, open diaphragm. Therefore, you have also to replace. And, basically, when we install that solution, sometimes our customers, ask it to also integrate with their control systems. So, therefore, they compress their generation, the fan, the hoppers, the safety alarms, of the plant sometimes are fully integrated as well. Now let’s talk very much about few features features because these are the ones that probably you haven’t seen yet. Wanna talk about our HMI control system is based on Movicon, Movicon next platform. And, basically, it provides everything that you know from the Scott HMI. And that’s why to use this in general for applications like OIE, energy management, in some others, infrastructure monitoring, like, smart cities, wastewater facilities, solar, mega mega plants, etcetera. Of course, it provides data visualization, but, I like to highlight that, you could ask we provide connectivity to all major POCs that you can imagine, with communication drivers. Of course, the open standards like OPC UA, like, Modbus. And on the lower part, the the green, let’s say, the the gray part here is what we used for that solution. Sometimes we use a geo maps, to indicate where the filters are. Some geo references, let’s say geo fences as well. The people have to be, with a personal protection equipment to be there. So there are some, real time, data that, of course, we are collecting for the particle emissions and other elements like differential pressure, header pressure. And then you have the headlines. You can see some screens that are completely dedicated to alarms and alerts. And one of these, diagnostics that you see are related to the solenoid, to the filter bag, and to the diaphragm diagnostics. A lot of them are diagnostic get diagnosed in different ways. For example, the solenoids, we look into the power output of our IO cards to see if the valve post the solenoid is open or complete short circuit. The filter bag, I already explained it. We detect with some logic with the the particle sensors, And the diaphragm diagnostics is based on the header pressure because if it’s this diaphragm is completely open, the differential pressure within the chamber, it starts fluctuating, and then you know that there’s something wrong there. But all of them increases the filtration efficiency, changes from reactive to predictive maintenance, of course, keeps the site compliant, minimize dust emissions, and for sure increase equipment lifetime, like the filter units, and reduce the compressed air usage. If you sum up all of that, the return in investment is it might be quite fast, of course, for large big large installations might be within two years, but it’s still a very fast return in investment for that particular solution. That’s what it looks like. A little bit, let’s say, zoom in. You see that they’re not nice looking, but they indicate graphically where the issues are, the number of issues, on this screen about thresholds alerts. The second one on the right side, is like the number of cycles. Imagine that every pulse valve would have, about a couple of millions of cycles of lifetime. Here, you can at least predict when or how many spare parts that, you need to have in the next quarter. And then, the yellow or red signals means that, red gone, you have is a faulty. And the white ones or the red the yellow ones are the ones that, you need to watch because they’re getting closer to the lifetime dead of lifetime. The other aspect is, like I said, when thus collector systems, you acquire that without the solution, it comes with this sequence box, which basically is a time based posting. So it keeps posting three to six minutes, like I I said, hundred milliseconds, but it can change. It’s it’s fixed. And that means that leads to, an excessive use of the post valve. So you’re going to wear out quite sooner than it should, but also reduce the valve back life because stretching the the the back filters, of course, you’re gonna also wear out, and you waste much more compressed air than than probably you should. That’s why we implemented this other two types of a post jet cleaning methodologies. One is on demand. That really depends on the high differential pressure between the the chamber and, you can set, in the in the solution how these multiple filter lines are going to operate normally, And this differential pressure threshold can be, for example, when the efficiency is getting bad, the differential pressure gets lower. And then if that is within a certain band, you can estimate that, there is accumulation of the cascade. The other one is very, intelligent. It’s a function block, in our PLC that, does a dynamic change. So, therefore, you put the single set point and the adaptive algorithm based on the virtual pressure starts controlling the intervals between the posts. So the idea is that to optimize by eliminating unnecessary posts in the cycle of these valves and also minimizing the compressed air. Of course, when you install the solution and, you put the set point for the first time, the system needs a little bit time to learn, and it’s a learning algorithm that, starts adapting. And very soon, it starts performing optimally. Okay? Shawn Tierney (host): Hey, everybody. I just wanna jump in here one more time. Just thank our members, both on YouTube and at the automationblog.com. I got some really exciting stuff coming up for you guys, in the fall. I’m I just have this huge plan that I’m working on. And so, I really just thank you guys for being members. Don’t forget, you get access to Discord. Don’t forget, there’s a whole library of older episodes you get to watch. It’s such just what I’m doing this month for members. It’s, you get a whole library of stuff. We did so much member only content over the last couple of years that you have hundreds literally hundreds of hours of content that you and only you get access to as a member, whether you’re on YouTube or you’re at theautomationblog.com. And, of course, if you have any questions about your membership, reach out to me directly, please. And with that, let’s go ahead and jump back into this week’s show. Eugenio Silva (Emerson): And that looks like that. This is just another, possibility to see. You see that, on the left side, you see a particular rows, and each of these rows have the filter bags. Each filter bag has a vertical bar that indicates the healthy of that solenoid diaphragm is on the top. And then, each of these compartments can navigate from one to another. Then you have other additional elements like the header pressure, differential pressure, particle density, and you have a trained diagram that, you are able also to generate reports, but you also also to to monitor, in order to to type a little bit, the parameters in order to be more efficient. And then, completely right side, if you have more than one dust collector, you can create different screens if you want. But the idea here is that the C1, C2 means compartment one, two, three. Again, a diagnostics that leads to preventative predictive maintenance and avoids completely reactive maintenance. Interesting, if you don’t know, in order to replace a single filter, in order to check if a solenoid valve is completely short circuits, In order to see if, a diaphragm valve is open, you needed to get there in this personal protection equipment using mask, gloves. You need to go up. You need to kind of get to know where these things are. And imagine that if you could avoid and just look at the screen and say, hey. I know that this is the compartment one of the filter a, and I know where I needed to look at. And by the way, I have the spare part because I had early indications to fix it. So then we are not just talk about reduction time, but, I guess, reduction costs and avoid to put people every time in such a very interesting environment. Okay? I’m not going through the the right part because you can imagine that this is a description of how things are usually done. And if you turn this around into a proactive predictive maintenance, then you have less and maybe faster steps. And you can prevent and can plan in advance when you wanna go with these, units, and you have to wear this equipment for protection. So very quickly in the developer position. Of course, like any solution, customers are interested to know if, they can pay off payback very quickly. So the return investment of that. So that’s why we check, the size, the number of, units, what’s the minimum size the customer could start with, because the it’s a pre engineered solution, how fast it could be that we implement in the whole site. It could be also, of course, calculate how much their current expenditure in terms of maintenance, reactive maintenance, the cost of utilities like compressed air, how many times they have to or they have downtime issues. And from that, we can prove very quickly, very simply that, it’s worth investing in automation. 20 to 30% of our reduction is a lot if you consider that they use a huge amount of compressed air. And compressors, they use electricity. So, therefore, if you’re able to reduce compressed air, you also increase your operation efficiency because cost of utilities is one of the points. Downtime is everything. Maintenance, it’s about preventing that you need to do these manual inspections. Just go there, check, and come back, and you see that, okay, we could wait for another week. But because I’m here, I’m going to change anyhow the filter. And that, of course, you’re not, increasing the lifetime of our equipment. And interesting that some downstream equipment, like the blowers, like the vacu pumps, if they get a lot of dust or excessive dust, they also, damage them. So therefore, maximizing maintenance, optimizing every step pays off in that sense. And finally, of course, customers do that because they want the full compliance. Every possible issue can be tracked, can be report. The efficiency of the systems can be audit ready, reports. It can re really prove that you can you are reducing part commissions. You provide a lot of visibility what’s going on. So, therefore, the technical teams are in very high confidence to operate the system. Because if without, they are operating blindly, And that’s why they feel a bit concerned many times that, might be that the bad things are just going to happen. In a nutshell, we talk about savings, extending the filter life. We talk about savings, reduce the compressed air. We can avoid downtime. Each downtime is one event that costs not only in the maintenance part here, but also the whole production costs that are not calculate here. And half the penalties that, if you have a single issue, it’s gonna be a big one. So, therefore, it’s a good way to give customers an idea why they should invest the CapEx parts and how we can help with the OPEX to save, their budgets in the sense of operating dust collector systems. So, Shawn, if I have time three minutes, I’m going to run this HMI demo because then you can see on the screen how the different screens are operated, but it’s up to you if I if I if if I need to do that. Shawn Tierney (host): Yeah. Go ahead. Eugenio Silva (Emerson): Okay. So this is an HMI demo, of course, simulated here because imagine it’s not possible to connect to live or to have all this whole equipment. So then I’m going to click here. So, basically, you see how a operator would navigate the type of information that, is provided. I made this click through very quickly because then we don’t owe too too much time here. But you see that, you are able to trend the particle density, the air consumption. You can set the alarms. You can indicate which boost valve is not okay. How is the level of filter bags? And now the settings. The cleaning, these are the parameters that you can adjust. Like I said, we have an adaptive learning algorithm, but in many cases, you needed to steer at least set up, the sensors as well, how sensible sensitivity of that. There are many different thresholds. And then the diagnostic part, for the diaphragm and the rupture where you can detect. And once this is done, you can see that, you have, quite, interesting information. For example, if you change, you devolve, you reset the counter. These are the alarms that you can acknowledge, etcetera. Okay? And, that’s it. That was the case. Shawn Tierney (host): Yeah. That gives you a good idea of what you’re getting with as far as the HMI is concerned, and, it’s good to see a full screen. I mean, it looks it looks like a very well designed HMI. From my perspective, it looks like it’s really giving you it’s focusing in on any errors. So you have, like, just standard graphics, a very good looking graphics, and then if there’s an error, you see it in red or yellow, really calls the eye to it. But, Eugeno, I see that, there’s a QR code on the screen right now. Can you tell people where that goes? Eugenio Silva (Emerson): Yes. It goes to the product page on our Emerson.com site. And from there, you can request for demo. We can request for proposal. We can request for more information. So this is the entry point for you to go to know, how it how we provide that solution, which kind of, basic elements. And there, we have also the related product pages if you wanna get, get to know more. Shawn Tierney (host): And I think the important part here is a lot of times you you, you know, when when you have a dust collector system that is that is constantly needing care, right, to keep you in compliance and make sure your products are products are being made correctly and you’re keeping people safe and all of that, You know, these systems, you’re gonna they’re they’re gonna be expensive. And, you know, larger systems, of course, are gonna be expensive. And so that cost savings, it’s like energy savings we do with VFDs on pumps and fans. Right? Or energy savings we do when we’re doing lighting, the folks over at Emerson are gonna wanna help you kinda quantify that because, you know, they know that for you to be able to justify not only, hey. This has given us a lot of problems. We know it’s costing us money. You also wanna know your ROI. Right? And so they’re gonna work with you on that because that’s on these big projects, those are those are some of the things that we have to look at to be able to, you know, to budget correctly. Anybody who has ever been in the budgeting part of a company knows you just don’t spend money because it’s fun. You know, you have to have a reason beyond everything. So I would I would guess I’m right on that, Eugenio. Eugenio Silva (Emerson): Yes. And, Shawn, although I just covered the technical part, of course, without any commitment, we can talk to customers and consult them Yeah. To look it around and see, in terms of maturity, how they operate this dust collector systems. We can, of course, check the install base. We have a questionnaire, that can fill it in. We can understand the size. We can, for example, talk about the energy consumption, the number of, hours that they are spend or active maintenance.

Hey Collectors! On this episode of the Hoardganize Podcast I discuss how to declutter your kitchen of potentially toxic items. Below are some of the utensils and cookware that may contain chemicals that are harmful to you and your family (don't forget your fur kids either). Utensils & Cookware That May Contain Chemicals 1. Nonstick Cookware (Teflon) Chemical: PTFE (polytetrafluoroethylene) and formerly PFOA (perfluorooctanoic acid) Risk: At high temperatures (over 500°F), nonstick coatings can break down and release toxic fumes. Tip: Use nonstick only on low/medium heat, avoid scratched pans, or switch to ceramic-coated alternatives. 2. Plastic Utensils & Storage Chemical: BPA, phthalates, and other plasticizers Risk: Heat (like dishwashers or microwaving) can cause plastics to leach these into food. Tip: Use BPA-free plastics, or switch to glass, stainless steel, or silicone. 3. Aluminum Cookware (especially uncoated) Chemical: Aluminum Risk: Acidic foods (like tomato sauce) can cause leaching; long-term exposure to aluminum is under investigation for health impacts. Tip: Use anodized aluminum or switch to stainless steel. 4. Copper Cookware Chemical: Copper Risk: Can leach into food if not lined (usually with stainless steel or tin). Too much copper can be toxic. Tip: Use only lined copper cookware. 5. Melamine Dishes Chemical: Melamine Risk: Can leach into food, especially when microwaved or used with hot foods. Tip: Avoid microwaving melamine and use ceramic/glass for heating. Remember, you can always see our episodes in person, on our youtube channel!

Welcome back to our weekend Cabral HouseCall shows! This is where we answer our community's wellness, weight loss, and anti-aging questions to help people get back on track! Check out today's questions: E.L: Hi Dr. Cabral, I had an endoscopy done in Jan 2024 and found gastrointestinal intestinal metaplasia in the stomach. In July I had a 2nd endoscopy done (to take a more deeper look and map it) and the results were the same and “stable” (no change), the Gastro said that it looked more like autoimmune gastritis because I tested positive for the antibody, she explained it to be one in the same. She said not to worry because the chances it become malignant (dysplasia and on) were slim and monitor it (repeat the endoscopy) in 2 years. Had a GI Map done per my Int Doc that ruled out H. pylori, which she said was not real data and disregarded it. Taking gastric gum and GI benefits, manuka honey on occasion. How long should I take these supplements for? For ever? What can I do? Can it be reversed? Alicja: Hi Dr. Cabral, I recently asked you about very high levels of vit. B12 that my blood work shows (despite not supplementing with B12, other than what's in my Multi) You said it may be a liver issue - that perhaps my liver is not processing my B12 and that's why the vitamin keeps circulating in my bloodstream. Can you please elaborate on this? How can I check if my liver does not process my B12? What kind of tests should I run for my liver? Thank you so much for your help. Alicja: Hi again. What is your opinion about electric cars? Is it true that they are big "EMF boxes" Ever since someone mentioned that, I can't help but wonder if it's true. I would love if you could make a show about this, perhaps with results of what EMF readers show inside a Tesla, Cyber truck and the self driving Weymo. Thank you again for spreading your amazing knowledge. Kelsey: Hi Dr. Cabral. I was wondering if you have heard of the brand of cookware called Hexclad. It advertises as getting the cooking experience of stainless steel, nonstick, and cast iron all in one hybrid pan. They say the nonstick is called TerraBond which is PTFE free and free from forever chemicals, and is a patented technology. Thanks for your input!! Jasmine: Hey there, Firstly, I want to thank you for all the podcasts you put out, and all that you give. I am in the best health now at 36 years old, because of how much I've learned & applied from all you've discovered and shared with us. I had my first baby last March, and plan to try for another next year, in hope that they are. somewhere close to 2 + years apart. I noticed the veins on my arms and hands enlarged during pregnancy and have remained enlarged post pregnancy (9 months now). They often ache. I started out at a healthy weight, 5' 9” 136lbs, gained 23 lbs during the pregnancy. I am wondering if there is anything I should consider doing/taking to help with the veins on my next pregnancy, maybe increasing my blood flow etc. would love to hear you thoughts. Thanks so much!

Steal can be caused by multiple factors—arterial occlusive disease proximal or distal to the AV anastomosis, high flow through the fistula at the expense of distal arterial perfusion, and failure of the distal arterial networks to adapt to this decreased blood flow. Incidence and Risk Factors The frequency of steal syndrome is 1.6-9%1,2, depending on the vessels and conduit choice Steal syndrome is more common with brachial and axillary artery-based accesses and nonautogenous conduits. Other risk factors for steal syndrome are peripheral vascular disease, coronary artery disease, diabetes, advanced age, female sex, larger outflow conduit, multiple prior permanent access procedures, and prior episodes of steal.3,4 Long-standing insulin-dependent diabetes causes both medial calcinosis and peripheral neuropathy, which limits arteries' ability to vasodilate and adjust to decreased blood flow. Patient Presentation, Symptoms, Grading Steal syndrome is diagnosed clinically. Symptoms after AVG creation occurs within the first few days, since flow in prosthetic grafts tend to reach a maximum value very early after creation. Native AVFs take time to mature and flow will slowly increase overtime, leading to more insidious onset of symptoms that can take months or years. The patient should have a unilateral complaint in the extremity with the AV access. Symptoms of steal syndrome, in order of increasing severity, include nail changes, occasional tingling, extremity coolness, numbness in fingertips and hands, muscle weakness, rest pain, sensory and motor deficits, fingertip ulcerations, and tissue loss. There could be a weakened radial pulse or weak Doppler signal on the affected side, and these will become stronger after compression of the AV outflow. Symptoms are graded on a scale specified by Society of Vascular Surgery (SVS) reporting standards:5 Workup Duplex ultrasound can be used to analyze flow volumes. A high flow volume (in autogenous accesses greater than 800 mL/min, in nonautogenous accesses greater than 1200 mL/min) signifies an outflow issue. The vein or graft is acting as a pressure sink and stealing blood from the distal artery. A low flow volume signifies an inflow issue, meaning that there is a proximal arterial lesion preventing blood from reaching the distal artery. Upper extremity angiogram can identify proximal arterial lesions. Prevention Create the AV access as distal as possible, in order to preserve arterial inflow to the hand and reduce the anastomosis size and outflow diameter. SVS guidelines recommend a 4-6mm arteriotomy diameter to balance the need for sufficient access flow with the risk of steal. If a graft is necessary, tapered prosthetic grafts are sometimes used in patients with steal risk factors, using the smaller end of the graft placed at the arterial anastomosis, although this has not yet been proven to reduce the incidence of steal. Indications for Treatment Intervention is recommended in lifestyle-limiting cases of Grade II and all Grade III steal cases. If left untreated, the natural history of steal syndrome can result in chronic limb ischemia, causing gangrene with loss of digits or limbs. Treatment Options Conservative management relies on observation and monitoring, as mild cases of steal syndrome may resolve spontaneously. Inflow stenosis can be treated with endovascular intervention (angioplasty with or without stent) Ligation is the simplest surgical treatment, and it results in loss of the AV access. This is preferred in patients with repetitive failed salvage attempts, venous hypertension, and poor prognoses. Flow limiting procedures can address high volumes through the AV access. Banding can be performed with surgical cutdown and placement of polypropylene sutures or a Dacron patch around the vein or graft. The Minimally Invasive Limited Ligation Endoluminal-Assisted Revision (MILLER) technique employs a percutaneous endoluminal balloon inflated at the AVF to ensure consistency in diameter while banding Plication is when a side-biting running stitch is used to narrow lumen of the vein near the anastomosis. A downside of flow-limiting procedures is that it is often difficult to determine how much to narrow the AV access, as these procedures carry a risk of outflow thrombosis. There are also surgical treatments focused on reroute arterial inflow. The distal revascularization and interval ligation (DRIL) procedure involves creation of a new bypass connecting arterial segments proximal and distal to the AV anastomosis, with ligation of the native artery between the AV anastomosis and the distal anastomosis of the bypass. Reversed saphenous vein with a diameter greater than 3mm is the preferred conduit. Arm vein or prosthetic grafts can be used if needed, but prosthetic material carries higher risk of thrombosis. The new arterial bypass creates a low resistance pathway that increases flow to distal arterial beds, and interval arterial ligation eliminates retrograde flow through the distal artery. The major risk of this procedure is bypass thrombosis, which results in loss of native arterial flow and hand ischemia. Other drawbacks of DRIL include procedural difficulty with smaller arterial anastomoses, sacrifice of saphenous or arm veins, and decreased fistula flow. Another possible revision surgery is revision using distal inflow (RUDI). This procedure involves ligation of the fistula at the anastomosis and use of a conduit to connect the outflow vein to a distal artery. The selected distal artery can be the proximal radial or ulnar artery, depending on the preoperative duplex. The more dominant vessel should be spared, allowing for distal arterial beds to have uninterrupted antegrade perfusion. The nondominant vessel is used as distal inflow for the AV access. RUDI increases access length and decreases access diameter, resulting in increased resistance and lower flow volume through the fistula. Unlike DRIL, RUDI preserves native arterial flow. Thrombosis of the conduit would put the fistula at risk, rather than the native artery. The last surgical revision procedure for steal is proximalization of arterial inflow (PAI). In this procedure, the vein is ligated distal to the original anastomosis site and flow is re-established through the fistula with a PTFE interposition graft anastomosed end-to-side with the more proximal axillary artery and end-to-end with the distal vein. Similar to RUDI, PAI increases the length and decreases the diameter of the outflow conduit. Since the axillary artery has a larger diameter than the brachial artery, there is a less significant pressure drop across the arterial anastomosis site and less steal. PAI allows for preservation of native artery's continuity and does not require vein harvest. Difficulties with PAI arise when deciding the length of the interposition graft to balance AV flow with distal arterial flow. 2. Ischemic Monomelic Neuropathy Definition Ischemic monomelic neuropathy (IMN) is a rare but serious form of steal that involves nerve ischemia. Severe sensorimotor dysfunction is experienced immediately after AV access creation. Etiology IMN affects blood flow to the nerves, but not the skin or muscles because peripheral nerve fibers are more vulnerable to ischemia. Incidence and Risk Factors IMN is very rare; it has an estimated incidence of 0.1-0.5% of AV access creations.6 IMN has only been reported in brachial artery-based accesses, since the brachial artery is the sole arterial inflow for distal arteries feeding all forearm nerves. IMN is associated with diabetes, peripheral vascular disease, and preexisting peripheral neuropathy that is associated with either of the conditions. Patient Presentation Symptoms usually present rapidly, within minutes to hours after AV access creation. The most common presenting symptom is severe, constant, and deep burning pain of the distal forearm and hand. Patients also report impairment of all sensation, weakness, and hand paralysis. Diagnosis of IMN can be delayed due to misattribution of symptoms to anesthetic blockade, postoperative pain, preexisting neuropathy, a heavily bandaged arm precluding neurologic examination. Treatment Treatment is immediate ligation of the AV access. Delay in treatment will quickly result in permanent sensorimotor loss. 3. Perigraft Seroma Definition A perigraft seroma is a sterile fluid collection surrounding a vascular prosthesis and is enclosed within a pseudomembrane. Etiology and Incidence Possible etiologies include: transudative movement of fluid through the graft material, serous fluid collection from traumatized connective tissues (especially the from higher adipose tissue content in the upper arm), inhibition of fibroblast growth with associated failure of the tissue to incorporate the graft, graft “wetting” or kinking during initial operation, increased flow rates, decreased hematocrit causing oncotic pressure difference, or allergy to graft material. Seromas most commonly form at anastomosis sites in the early postoperative period. Overall seroma incidence rates after AV graft placement range from 1.7–4% and are more common in grafts placed in the upper arm (compared to the forearm) and Dacron grafts (compared to PTFE grafts).7-9 Patient Presentation and Workup Physical exam can show a subcutaneous raised palpable fluid mass Seromas can be seen with ultrasound, but it is difficult to differentiate between the types of fluid around the graft (seroma vs. hematoma vs. abscess) Indications for Treatment Seromas can lead to wound dehiscence, pressure necrosis and erosion through skin, and loss of available puncture area for hemodialysis Persistent seromas can also serve as a nidus for infection. The Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines10 recommend a tailored approach to seroma management, with more aggressive surgical interventions being necessary for persistent, infected-appearing, or late-developing seromas. Treatment The majority of early postoperative seromas are self-limited and tend to resolve on their own Persistent seromas have been treated using a variety of methods-- incision and evacuation of seroma, complete excision and replacement of the entire graft, and primary bypass of the involved graft segment only. Graft replacement with new material and rerouting through a different tissue plane has a higher reported cure rate and lower rate of infection than aspiration alone.9 4. Infection Incidence and Etiology The reported incidence of infection ranges 4-20% in AVG, which is significantly higher than the rate of infection of 0.56-5% in AVF.11 Infection can occur at the time of access creation (earliest presentation), after cannulation for dialysis (later infection), or secondary to another infectious source. Infection can also further complicate a pre-existing access site issue such as infection of a hematoma, thrombosed pseudoaneurysm, or seroma. Skin flora from frequent dialysis cannulations result in common pathogens being Staphylococcus, Pseudomonas, or polymicrobial species. Staphylococcus and Pseudomonas are highly virulent and likely to cause anastomotic disruption. Patient Presentation and Workup Physical exam will reveal warmth, pain, swelling, erythema, induration, drainage, or pus. Occasionally, patients have nonspecific manifestations of fever or leukocytosis. Ultrasound can be used to screen for and determine the extent of graft involvement by the infection. Treatments In AV fistulas: Localized infection can usually be managed with broad spectrum antibiotics. If there are bleeding concerns or infection is seen near the anastomosis site, the fistula should be ligated and re-created in a clean field. In AV grafts: If infection is localized, partial graft excision is acceptable. Total graft excision is recommended if the infection is present throughout the entire graft, involves the anastomoses, occludes the access, or contains particularly virulent organisms Total graft excision may also be indicated if a patient develops recurrent bacteremia with no other infectious source identified. For graft excision, the venous end of the graft is removed and the vein is oversewn or ligated. If the arterial anastomosis is intact, a small cuff of the graft can be left behind and oversewn. If the arterial anastomosis is involved, the arterial wall must be debrided and ligation, reconstruction with autogenous patch angioplasty, or arterial bypass can be pursued. References 1.

The Accidental Discovery That Gave Us ‘Forever Chemicals' | A Pregnancy Play Inspired By Mushroom Research

The Accidental Discovery That Gave Us ‘Forever Chemicals'When it comes to PFAS chemicals—known as “forever chemicals”—we often hear that they're used in nonstick coatings, flame retardants, and stain repellants. But those examples can hide the truth of just how widespread their use has been in modern life.A new season of the “Hazard NJ” podcast looks at the origin story of PFAS chemicals, and the accidental discovery of PTFE—aka Teflon—in a DuPont laboratory in southern New Jersey. “Hazard NJ” host Jordan Gass-Pooré joins guest host Kathleen Davis to talk about the history of PFAS, their effect on the environment and health of New Jersey residents, and work towards cleaning up the PFAS mess.A Play About Pregnancy Inspired By Mushroom ResearchPeople are finding all sorts of uses for mushrooms these days, but we're going to focus on two of them: how scientists are using them in robots and how playwrights are using them in theater. A few weeks ago, SciFri producer and host of our “Universe of Art” podcast D Peterschmidt moderated a panel at the Science In Theater Festival in Brooklyn, New York.The festival is put on by a company called Transforma Theatre that stages science-inspired plays. Each year, they pair playwrights with scientists to make short plays that explore the research focus of the scientist.Director and playwright Hannah Simms was paired with Dr. Andrew Adamatzky, a professor of unconventional computing, who's learning how to connect various parts of nature, like mushrooms, to computers, and consulted with Hannah during the writing process. The play, called “Fruiting Body,” is about a fungal-computing scientist who, while pregnant, creates a fetal heart monitor powered by mycelium, which turns out to be sentient. While the concept is definitely science fiction, it is based on real unconventional mushroom research.D talks with Hannah to learn why she wanted to explore her pregnancy through the lens of mushroom research. They're also joined by Dr. Anand Mishra, a research associate at Cornell University's department of mechanical and aerospace engineering, who explains how he helped build a robot that's powered by king oyster mushroom mycelium.Transcript for this segment will be available after the show airs on sciencefriday.com.

4 Types of Toxic Cookware to Avoid and 4 Safe Alternatives

Bright Side

We all know the importance of eating healthy, but not everyone knows that the cookware you use to prepare your dishes is just as important as the food itself. Even the healthiest diet can result in severe health problems if your pots and pans are toxic. Find out which cookware you should avoid by all means for the sake of your own health and the health of your family. The non-stick properties of Teflon cookware are achieved with a coating of PTFE. This is a plastic polymer that, when heated above 572°F, starts to release toxins. These toxic fumes lead to flu-like symptoms called polymer fume fever, informally known as Teflon flu. Another chemical compound found in Teflon cookware is especially threatening since it tends to stay in the body (as well as in the environment) for long periods of time. Try cast-iron cookware instead. It even comes in non-stick varieties. It doesn't leak anything toxic into your food and is actually a nice natural way to increase your body's iron levels. Though aluminum cookware is usually coated, the coating is prone to chipping, allowing the toxic metal to get right into your food. As for aluminum foil, using it while cooking is even more dangerous. In fact, there's an established safe amount of aluminum the human body can manage daily, and that's 20 mg per pound of body weight a day. When you wrap your food in aluminum foil and cook it this way, the amount of this substance that leaks into the food significantly exceeds the permissible level. Consider using glass cookware instead. If you've just enjoyed some fish in lemon juice or stewed tomatoes cooked in an uncoated copper pot and you find yourself suffering from extremely unpleasant symptoms (such as vomiting blood, light-headedness, yellowy skin, or gastrointestinal distress, among others) call 911 immediately. Try this safe alternative instead: stainless steel. Just make sure you're buying food-grade stainless steel since this is the only type that doesn't contain any nickel or chromium. Soft ceramic coating isn't durable enough and starts chipping after a few months of daily use. When this happens, lead and cadmium sometimes found in the coating will end up in your food and, thus, in your body. Lead poisoning is one of the most dangerous types of metal poisoning and can result in abdominal pain, headaches, infertility, and other health complications. Try this safe alternative instead: 100% ceramic cookware.

And if you're a veteran Protruserati, thanks for coming time and time again. We hope to make complex topics in dentistry tangible for you. Protrusive Dental PearlBefore we join the main interview with Dr. Mahmoud Ibrahim, I'm going to give you the Protrusive Dental Pearl, which I always do for every main PDP episode. Today's Protrusive Pearl relates to cramp operations, and in particular, getting better impressions or scans. Look, once you've placed the retraction cord, and I know many people like to use things like Expasyl or Traxodent, which are like the pace systems. I quite like using retraction chords and also in combination with PTFE tape, especially as I do lots of vertical preparations or VertiPreps. Now I have got lots of webinars planned in October. As part of the live series I'm doing for the Protruserati, the premium subscribers, it's going to be VertiPrep for Plonkers. So that's coming soon. And one of the strategies I use to be able to scan subgingivally is once I've got my triple zero cord in place, I will put some PTFE tape over that. But sometimes what can happen is that the gingiva it sulks, right? It sulks on to the PTFE and sometimes even contacts the prep. So when I scan it because the tissues because the gums are touching the preparation it creates a nightmare scenario for my technician who wants that gingiva well out of the way So at that point the pearl the tip i'm giving you is if you've got a laser, fine. Great. Use a laser. If you've got any fancy burrs, use them. But the cheapest thing you can buy is something called a Thermocut Bur.

And are there any ways to get rid of them? Thanks so much for all you do. Audrey: Hi Dr. Cabral! 2 questions here: 1. I listened to your podcast on branch chain amino acids found in food. I wanted your opinion on supplementing with it. I know EquiLife does not carry them so was just curious why. 2. I've been hearing lots of conflicting evidence that taking collagen does not work. Can you explain how collagen actually benefits the body? Thanks so much! Alicja: Hi Dr.Cabral, I have a question related to my teeth. I pulled out teeth that had root canals done and now I have zirconia implants instead. For the first implant my dentist used cement to attached the crown and I stopped sleeping for a month after that. For the second implant - to avoid cement, he used a screw and plumbers tape. My sleep stayed good, but I started getting daily headaches. I googled plumbers tape and it turns out it's "teflon tape" made from PTFE! (my mind was blown!) My headaches went away after 2 weeks, but I can't make peace with the teflon tape. Do you think it's safe to have it as long as there is no high heat? I like using infrared sauna a few times per week (heats up to 145F) At what temp. does PTFE releases harmful chemicals? Should I replace the tape with cement? Alicja: Hi again, my second question is about garlic. Raw garlic is one of the remedies I use when I get sick. Despite lower appetite and eating very little during sickness, I usually get more bloating and lot's of white coating on my tongue. Garlic is called "natural antibiotic" because it can kill bacteria and other pathogens, but it also is reach in prebiotic, right? So it means it can feed bacteria. Which one is it then? Does garlic feed bacteria, or kills them? Thank you for all your amazing work! I listen to your podcast daily and learn so much from you.

Welcome back to our weekend Cabral HouseCall shows! This is where we answer our community's wellness, weight loss, and anti-aging questions to help people get back on track! Check out today's questions: Erin: Hi Dr Cabral, I have extreme salt cravings part of which are due to adrenal issues and the other thing. I just enjoy the flavor profile I have always preferred highly salted food. I had been experiencing swollen eyelids in the morning and then I heard it often times it's not about how much sodium you intake but instead your sodium to potassium ratio. I started taking potassium in the form of cream of tartar mix into my magnesium sweet drink before bed, and it seems to be working as a swelling has reduced. I'm curious to hear your thoughts on the sodium potassium ratio, and whether you can balance that are really need to reduce salt intake? Burg: Hey Doc, love your work. After a routine visit to the doctor, he noticed a crease in both earlobes and said that it might corollate to heart issues. It's called “Frank's Ear". I am 58 and overweight. I have noticed a loss of connective tissue (loose wrinkly skin) over the past few years. Any thoughts would be appreciated. Marina: Hi Dr Cabral, I'd like to know the benefits of fish oil vs cod liver oil. Cod liver oil has vit a and d however you say that EPA to DHA of 2:1 is best, cod liver oil doesn't seem to meet this. When should we pick one over the other? Or supplement with both? Thank you Anonymous: Hi, dr. Cabral.. My boyfriend bought these expensive pans from Hexclad because “even Gordon Ramsey uses them” and they are advertised as non-toxic.. I wrote an email to them and they said that of course they use PTFE to make them non-stick and that US FDA certified it for use in many applications including medical implants and cookware.. After listening to your podcasts I believe it's still toxic to our bodies, but not sure if you've used the name PTFE.. Can you please tell us your opinion on it? Lara: Hello, dr. Cabral.. I went to an Ayurvedic doctor who said I was a pitta by looking at my fingers and nails.. I'm wondering about two things that he said: - the moons on the fingernails shouldn't be visible- if they are, there's a problem with corresponding organs - chocolate, even raw cacao is poison, because there is a scarcity of it in the world and it would have to be extremely expensive if it was natural.. in his opinion it is all made in a lab.. Could you please give your opinion on both? Thank you so much and happy healing to everyone!

Schneider, MD and Endovascular Skills - history, personal techniques and updates in the 4th Edition Closure devices: Angioseal Mynx Proglide Endovascular procedures are minimally invasive techniques used to treat conditions affecting blood vessels, such as aneurysms, stenosis, or occlusions, by accessing the affected vessels through an incision in a peripheral artery and using imaging guidance to navigate catheters and devices through the blood vessels to the treatment site. Endovascular procedures can be broken down into 4 key steps Establishing arterial access Navigating to target treatment zone or vessel Treating the lesion Closure Basic definition of wire, sheaths, and catheters Wires are thin, flexible metal devices used to navigate through blood vessels and to guide other devices, such as catheters or sheaths, to the target location. They are measured in thousands of an inch A 0.018 wire is 0.018 inch in diameter There are two categories of wires: Flexible and support Flexible wires are soft and hydrophilic. They are considered the “workhorses” because they are useful for navigating through vessels. A common type of wire is called the Glidewire which is slippery and useful in traveling across tortuous vascular anatomy. Support wire are generally a lot stiffer and not hydrophilic. For that reason they are used to deliver and deploy devices A common type of support wire is called the Lunderquist which is used for the deployment of stent grafts in endovascular aortic repair Catheters are flexible hollow tubes used in conjunction with wires to navigate vascular anatomy Various characteristics include the degree and shape of the taper, the lengths, and the stiffness. They are inserted inside the sheath Sheaths are hollow tubes of various diameters that are inserted into a blood vessel to provide a pathway for catheters or wires. They have a one way valve to prevent backflow of arterial blood and a side port that permits aspiration and administration of fluids. They also come with a dedicated dilator which is used to fill the lumen of the sheath and allows the surgeon to insert the sheath safely into the vessel. If the wire is the rail and the catheter is the train, the sheath is the ground. Sheaths and catheters sizing Both are measured in French 1 French equals 0.33 mm. French size divided by 3 equals the approximate diameter in millimeters. Another way to think about Fr is roughly the circumference in mm. Divide by 3 instead of 3.14 to get the diameter Sheaths are defined by their inner diameter (ID) Catheters are defined by their outer diameter (OD) This is because catheters go inside the sheath, so the size of a catheter must be smaller or equal to the size of the sheath for it to fit inside.For example, a 5 Fr sheath can accommodate 5 Fr catheter/devices Of note, the hole in the artery will roughly be 2-4Fr larger than the sheath size. This is important when considering the type of closure that will be used at the end of the procedure. Step One: Establishing Arterial Access Preop preparation: During physical exam, make sure there's a palpable femoral pulse to rule out iliofemoral disease Review the CT if available for high femoral bifurcation or presence of vessel disease Patient positioning on the angio table, depends on the access site of choice. Typical position (for retrograde femoral artery access) is supine, arms tucked. Alternative access sites (ie. radial, brachial, carotid) may require arms to be out and prepped. How do you choose arterial access, location? Depends on location of lesion you are trying to treat and complexity of the path from the access site Size of the access vessel and device size must be considered when deciding on the access site The most common is retrograde femoral artery access When would other access points be used? Radial artery, brachial, antegrade femoral access. The goal, target location, and path complexity defines the access point. Arterial puncture Femoral access: Look for pulsatile vessel on the US (vein is medial, artery is lateral; “venous penis”) Usually access at the level of femoral head for common femoral artery Seldinger technique is used to establish access to a vessel or cavity using needle, wire, catheters, and sheath. E.g. using the micropuncture kit: contralateral arterial CFA access with s 21 gauge needle .018” guidewire is passed through the needle Needle is removed and a short 4 or 5 Fr microcatheter with an inner dilator is passed over the guidewire The dilator and guidewire are removed leaving the catheter in place to maintain access Bigger wire is inserted through the catheter, which is then removed over the wire A sheath is inserted over the wire The overall purpose is to start with smaller arterial puncture and exchange to larger size to minimize complication should the access fail Often, percutaneous closure devices are preloaded at this step. We will discuss this later. Step Two: Navigating to treatment zone or vessel With sheath in place, a guidewire is inserted into the vessel under fluoroscopic guidance. Continuous fluoroscopy is taken with the C-arm during key steps to visualize wire movement The C-arm can be portable or built into the room X rays are emitted from the X-ray generator below the patient And the subsequent image is generated from the image intensifier above the patient Radiation safety: wear protective gear which is made of lead. In addition, use the tableside lead shield whenever possible minimize use of continuous fluoroscopy whenever possible limit use of magnification, and digital subtraction angiography keep the image intensifier as close to the patient as possible to minimize scattering The C-arm can rotate around the patient to get optimal viewing of the vessels Frequently used terminology: 30 degrees RAO which stands for right anterior oblique, describing the relationship of image intensifier to the patient Common projections used for lower extremity angiograms Iliacs: 20-30 degrees contralateral anterior oblique Femoralsl: 20-30 degrees ipsilateral anterior oblique Trifurcation and tibials: anatomic anterior-posterior or 20 degrees ipsilateral anterior oblique with feet in neutral supine position Thoracic aorta/distal aortic arch: 30~45 degree LAO Renals: AP maximizing image quality by limiting patient movement and with breath holding and collimating Contrast Two types of contrasts: Iodinated contrast vs carbon dioxide Iodinated contrast has better resolution but patients can have allergic reactions and are at risk of contrast induced renal injury. Therefore, CO2 is preferred for patients with compromised renal function in which an image is created by transiently displacing blood. The downside is that it has lower image resolution than iodinated contrast, and rare but potentially serious complications of air locking. Power injection vs manual injection When using power injection, you have control over pressure, the amount of contrast, timing, and rate or rise of injection. It allows for rapid filling of large arteries at high flow rates. Manual injection is more efficient for small vessels since you can control dilution and volume Types of Wires Characteristics: wire tip, stiffness, diameter, and length Guide wires To assist in catheter placement, navigate different arteries, cross lesions, and deliver devices. The most common sizes used in vascular surgery Large .035” - generally used for the aorta and iliac. Small .014”/.018” - used for smaller branches like the SFA Length: from 120 to 360cm Based on distance from access site to the lesion Long enough to reach target lesions and beyond (inside pt) and deliver catheters (outside pt) but not too long that it's falling off the table and slowing down exchange Flexible vs stiff/support wires How do you decide which wire to use? Typically, you start with flexible wire inside an angle tip catheter to navigate to the target vessel. Once you reached and crossed the target vessel, the wire is exchanged to a stiff/support wire, which allows you to deliver common brands and models used that every medical student should know and the settings they are used in? Example answer: Glidewire (Tumero): a floppy wire with a hydrophilic coating which is useful for navigating stenosis and tortuous vessels and is used in a variety of different vessels. Lunderquist (Cook): it is very stiff and used for endovascular repairs of AAAs Rosen wire: support wire with a J tip with intermediate stiffness. Less stiff than Lunderquist. Used to catheterize visceral and renal arteries. Bentson: starter wire, that's short in length with a very long floppy tip that prevents vessel trauma. Types of Catheters Main purpose of the catheters Allows to approach the target vessel based on the shape of the catheter Allows wire exchange from flexible to stiff Sizes are based on Fr (4-5) 5 Fr are the most common. Microcatheters are for embolizations (2.5Fr) Nonselective (Angiographic catheter) Common types are omni flush, pigtail, and straight They have multiple side holes along the tip so they can inject high volume of contrast into large blood vessels like the aorta Selective catheters/Guide (shape) catheters Have an end hole only with no side holes so they can cannulate specific branch vessels A variety of lengths and shapes depending on the curvature and tortuosity of the pathway to the target vessel. Catheter with specific shapes can align your vector (the force you are exerting by pushing the wire forward at the access site) to the stenotic lesion. Type of catheter that can be used to cross to the contralateral side at the aortic bifurcation – generally the omni. Types of sheaths Size range: 4-26Fr (larger available for endografts) Size is decided by the device you have to deliver to the target lesion Length is based on the support required from the procedure. The distance from the access site to the target site determines the length of the sheath required. Common lengths range from 5 to 110cm What are some of the common sheaths used and for which procedure? For endovascular aortic repairs, Dryseal sheaths range from 12Fr ~ 26Fr with lengths of 33cm to 65cm. For visceral and renal artery intervention, Ansil or Raabi sheaths range from 5Fr to 9Fr, with lengths of 45cm to 90cm. For lower extermity work, Ansil, Raabi, Balkin sheaths ranging from 4Fr to 7Fr with lengths of 45cm to 110cm. Steerable sheaths can actively articulate the shape of the sheath, allow you to navigate and treat more challenging anatomy. Step Three: Treating the lesion The lesion has to be crossed with wire and catheters before treating the lesion. They may require the need to exchange sheath Stent and balloon sizing is measured by diameter in millimeters x length in centimeters Balloons Generally need to exchange wire to stiff support wire through the catheter, then the catheter is exchanged over the wire with the balloon mounted catheter Balloons have a wide variety of diameters and lengths Nominal vs Burst pressures Nominal: pressure is where the balloon will inflate to the labeled diameter Burst: pressure where 99.9% of tested balloons ruptured Typically you inflate to nominal but can go higher depending on the type of lesion Compliant balloon vs a semi-compliant vs non-compliant balloon Most of the time, we use a compliant balloon, but in certain situations where we need high pressure dilation, we use non-compliant balloon. This has to do with the nature of the lesion and risk of vessel rupture. Additional features Cutting balloons have microblades on the wall. So the idea is to perform control rupture of calcified atherosclerotic lesions, so that the expansion happens more evenly. Drug coated balloons are coated with paclitaxel to reduce the risk of neo-intimal hyperplasia So, it is sometimes used in peripheral cases where the surgeons feel that the lesions are more prone to developing neo-intimal hyperplasia or areas that have restenosed. Stents small mesh-like device made of metal that is used to prop open a blocked or narrow blood vessel. It is inserted through a catheter and deployed at the site of the blockage to improve blood flow and reduce the risk of future blockages. balloon expandable vs self-expanding stents Balloon expandable Better radial force at the time of deployment More accurate deployment Mounted on balloons, so it is more difficult to track them across tight stenosis. May cause damage to the surrounding tissue due to balloon inflation. Self-expanding Usually more flexible in tortuous vessels More resistant to kinking Higher risk of migration or dislodgement during deployment Post-dilation is often needed covered stents vs bare metal stents Covered stents Covered by PTFE, polyurethane, or silicone May be more resistant to in-stent restenosis, compared to bare metal stents. useful in ruptured vessel EVAR/TEVAR/FEVAR devices are essentially fancy covered stents. Step Four: Closure Hole in the artery is outer diameter of the sheath, and is bigger than the sheath size since sheath is measured by inner diameter Manual compression Direct pressure with fingertips Enough pressure without bleeding, but not too much that it cuts off circulation No peeking! Timing depends on sheath size, coagulation status, and vessel health. Closure devices Extravascular plug Angio-seal: sandwiches the arteriotomy with a biodegradable anchor and collagen sponge. https://www.youtube.com/watch?v=XhgAs2SxNjA Mynx: utilized a small balloon to create temporary hemostasis within the artery and covers the outside with a polyethylene glycol sealant. https://www.youtube.com/watch?v=_kcJM1lnQo8 Suture-based Sometimes placed at beginning of the case for large bore access Proglide: https://www.youtube.com/watch?v=Wol22SlEpxE Complications What are the most common complications that you experience and how do you mitigate them?

Over the past few years you've probably noticed the brand Stio on the slopes. Born in the Mountain West, the company has become known for its extensive colors and a serious focus on technical materials that are sustainable. Last Chair did a visit with Stio Senior Materials Manager Sandy Flint to learn more about its products, which are both revolutionizing outdoor clothing performance and utilizing technology which is more friendly to the environment we all love so much.Stio was founded in 2011 by Mountain West native Stephen Sullivan, who had previously started the Cloudveil brand. Stio quickly became known for its focus on core technical apparel, fun colorways and direct-to-consumer sales. Today, the company has its own Stio Mountain Studios at major resorts across the west, including Utah on Park City's historic Main Street.Flint grew up in the Northeast, skiing around New England and taking family trips out west. “It was the mountains I loved – being able to hike, raft and ski.” He went to college in Colorado, then moved to Utah, teaching skiing at Solitude. With a degree in engineering and a background in art, he found his way into a graduate program studying fiber science and apparel design at Cornell. The combination of those technical skills with his passion for art landed him at Stio.What you quickly learn in talking to Flint is his passion for sustainability, and knowledge of how to find that pathway. Most of all, you learn that he's not alone, working at a company focused on the future. Today, preferred materials comprise 48% of Stio's collection and the brand has a goal to meet 75% by 2025.We also learn that sustainability is about more than just raw materials. It's an accounting of everything the company does from travel to manufacturing to shipping to recycling. Everyone in the company is accountable!In this episode of Last Chair, Flint dives deep into the science and history of membranes and other materials. One of the most notable transitions is the evolution from the polytetrafluoroethylene (PTFE)-based Gore-Tex of the past to environmentally-friendly ePE membrane that is per- and poly-fluorinated chemical (PFC) free.
