Today we do a round-up of some of the recent semaglutide trials. Does semaglutide ever miss? But what about tirzepatide, which causes even more weight loss?We also review two new critical care trials, FLUID and the UK-ROX, new platelet transfusion guidelines, and a new retrospective study of apixaban vs rivaroxaban vs warfarin.

In today's VETgirl online veterinary CE podcast, we discuss the potential development of an autoimmune response against platelets following live virus infection from canine influenza, and separately following vaccination with distemper (DA2PP) vaccine. Have you ever wondered before in your immune-mediated thrombocytopenic patients whether or not recent vaccination could have been the inciting factor for this autoimmune condition? Well, Williams et al. sought to get us the veterinary evidence that can tell us if viral infection or vaccination can cause this autoimmune dysregulation in our canine patients as described in their article entitled “Effects of Canine Influenza Infection and DA2PP Vaccination on the Development of Platelet-Associated Immunoglobulins and Platelet Counts in Dogs.”
In this week's episode we'll learn about tracking the functional profile of aging platelets. Researchers demonstrate that over time, platelet function shifts away from hemostasis and toward a more immunomodulatory role. These finding could have important implications for transfusion medicine and certain platelet-related disease states. After that, use of odronextamab, a CD20×CD3 bispecific antibody, in patients with diffuse large B-cell lymphoma, or DLBCL, progressing after CAR T cell therapy. The study is the first to evaluate the efficacy and safety of this therapy in the post-CAR T cell treatment setting. Finally, we will recap findings from a study of a novel CAR T-cell product that utilizes specificity to two antigens common in diffuse large B-cell lymphoma.Featured Articles:Aging platelets shift their hemostatic properties to inflammatory functionsOdronextamab monotherapy in R/R DLBCL after progression with CAR T-cell therapy: primary analysis of the ELM-1 studyDissection of single-cell landscapes for the development of chimeric antigen receptor T cells in Hodgkin lymphoma

Thank you for joining us for our 2nd Cabral HouseCall of the weekend! I'm looking forward to sharing with you some of our community's questions that have come in over the past few weeks… Anonymous: Hi Dr Cabral. I'm looking for advice to help my 8 year old daughter. She had a verucca last year that was persistent, it eventually cleared up with over the counter treatment. The verucca has come back this year and is really not shifting & it appears to be getting worse/larger. I have tried taping it, shop bought treatments and home remedies using garlic etc. What would you recommend? Thank you for sharing all of your wisdom. Kirsten: Hi Dr. C! Thank you so much for what you do! I enjoy listening to your podcasts daily! I took the MTHfr test and I was told that I carry one abnormal copy of two Mthfr genes. It looks like I am heterozygous for both.. Can you explain to me what this means and what I need to do to treat it please? I also have Hashimotos but not sure if that's connected or not.Thank you! Angie: Hello Dr. Cabral,My recent lab results indicate platelets low at 147 which is concerning. Gi Doctor said i have at two low labs and she is not concerned since it's a trend with prior labs. What could be wrong and what is your suggestion for a resolution ? Other labs - which are concerning Hemoglobin @16.5 (high) HCT @50 (high) Glucose @101 (high) And diagnosed with IBS.I appreciate any guidance. Thank you for all you do ! Christina: Hi Dr. Cabral! First, thank you for your generosity with your knowledge & time & the team you have built around you. I'm so grateful for the community. Now to the question: 3 months ago I started eating chicken and beef again after 15 years of a pescatarian diet. I have noticed that since that time, my frequency of burping has increased. I thought maybe my microbiome and digestive system needed time to adjust, but also thought by 3 months it would have subsided. This is the only change I've made in my diet; all other habits are the same - sleep, frequency of workouts, environment, supplements, etc. The burps come on suddenly which can be sort of embarrassing and if I try to hold them in, it causes acid reflux. What do you suggest I do? Julianna: Hello! Thank you for reviewing my situation. I am female, age 22. As many women my age, I have been dealing with acne for a while, but got much worse around age 20 (didn't have much of a problem in high school). It appears to be fungal and comedonal acne all the time and some cystic acne around my period. Many small spots on my chin, forehead, and nostril area, sometimes in the area above my top lip. I've seen a dermatologist for the past 2 years, on Doxycycline pills, tretinoin cream, and clindamycin lotion. This helped clear my skin pretty well but not completely. I recently stopped all of these, I want to find more natural solutions to whatever is causing the acne, and the acne has, of course, come back. I try to eat clean and use low-tox products. What can I do to solve this?

Hannah's appetite was good at this point, probably stimulated by the steroids, and she still enjoyed going out to eat. With her poor vision and motor skills, it was a bit of a challenge getting her in and out of restaurants ... but if she wanted to go, we took her. On this particular day, it was Macaroni Grill, and she enjoyed her favorite dish -- Penne Rustica. Thank you for joining me for another bonus episode of the While We're Waiting podcast in this year-long series in which I share our family's experiences as our teenage daughter Hannah battled glioblastoma brain cancer from February 2008 through February 2009.

Got a story idea for Bloodworks 101? Send us a text message Most platelet donations are stored at room temperature, sacrificing shelf life for circulation time in a patient's body. But patients who are actively bleeding don't need platelets to last for a long time — they need them to get to work, fast. The Stolla lab at Bloodworks Research Institute is investigating the efficacy of cold-stored (refrigerated) platelets, and Bloodworks is in a unique position to help.Learn more: bloodworksnw.org/research
After Christmas, my brother and sister-in-law came to spend a few days with us. This was a very special treat because they are career missionaries, and years could pass between their visits. They were able to accompany us to one of our Children's Hospital platelet infusions, and I took one of my favorite photos of Hannah with her cousin that day. It was also one of the last photos taken of her before things really began to unravel.

Check it out today! Now, time for this episode. In this episode, we're going to talk about the bloodstream, or as some call it, the circulatory system. [TRANSITION-2] Your heart is like the engine of your circulatory system. Your heart pumps blood through small rivers called arteries and veins. Your muscles need oxygen. Blood is like a shipping container that holds oxygen. Arteries go from your lungs to your muscles. Arteries bring blood that has oxygen to your muscles. Muscles trade blood for carbon dioxide. That's why you breathe oxygen and exhale carbon dioxide! [short pause] Veins take the carbon dioxide blood and bring it to your lungs. The heart powers all of this by pumping the blood. When veins with empty blood reach the lungs, the lungs give oxygen to the blood. Then, the blood travels through arteries since they have oxygen. Now, let's talk about blood cells. Red blood cells are the shipping containers. They contain oxygen. White blood cells are the body's army. They eat up any viruses or sicknesses in your blood. The reason you cough and get a fever is the result of the white blood cells fighting. Platelets are little cells that act like band-aids. Have you ever gotten hurt and then the spot dried up? That is a scab. Scabs contain platelets. The platelets cover up the spot so viruses and diseases can't get it. It's like when the walls of your body's castle breaks because of an injury, the soldiers quickly put up a wall. Platelets are the bricks the soldiers use to cover up the hole. Time for fun facts! 1. Throughout your life, your heart will probably pump 2.5 billion times! 2. If the blood cells in your blood were stacked one on top of another, it would reach 12% to the moon! That's 6,200 times the height of Mount Everest and 516 times the distance to space. 3. Bones make blood! 4. Your bloodstream is 60,000 miles long! That's 1/4 of the way to the moon! Thanks for listening! I hope you enjoyed this episode. The next one is going to be about the Olympics! [END SCRIPT]

2024 - Week 17 - Pinochle, Platelets and Resident Alien All the links: Linktr.ee/barbarafaison Doing new things is great for your brain. I am an LL- a lifelong learner and I'm grateful that for the most part I enjoy trying new things. I've been doing new things so long it really is second nature for me, most of the time. Watching a genre of a movie or a series you normally wouldn't watch is doing something new. It can also be picking up something new when you go grocery shopping or turning down a different street on your way home. It doesn't have to be major, just something “different” from the usual. This week I did three new things: Pinochle, donated platelets and watched Resident Alien on Netflix. Pinochle Last weekend I went over to my friend Kym Kennedy's house for a birthday celebration. At these gatherings, we pretty much hang out for the day. It's always a lot of fun and people come and go based on their availability. I arrived mid afternoon after a four hour shift working at the local library. We offer passport processing at our branch and Saturday is usually very busy. I was looking forward to it and relaxing. After greeting the ladies that were there, I grabbed a plate of food and sat down to join the festivities. We laughed and talked, and then started to play cards. I grew up playing cards which included tonk, bid, whist, gin rummy, spades to name a few. The card game they started to play was pinochle. I don't recall ever playing pinochle. I was up for something new. Why not? When the ladies started to explain the game and pulled out a piece of paper to write down how to score, I thought to myself this will take a lot of mental energy. Lol. Not quite what I expected and not very relaxing. I laughed with them that pinochle required a lot of thinking. These ladies are older than me and had been playing pinochle since they were in their teens or earlier. The birthday guest of honor, Elona and I were the ones learning how to play the game. I joked and complained a bit as they were explaining how to play, and I loved how they talked us through all the steps. It was a lot of fun after I got out of my head about all the thinking required. Donating Blood Platelets Yesterday I donated blood platelets for the first time after receiving a request from a friend who had a family member who needed them. I've donated blood numerous times, so this is definitely something new and different. The process was very streamlined with the application and forms being online, I was ready to go. I am a bit of a researcher so I did go to YouTube to know what to expect. I didn't say doing new things didn't mean you couldn't research, did I? Lol. I was in an out a within few hours. Resident Alien The third recent new thing I did was start watching Resident Alien on Netflix. It's a science fiction series about an alien who comes to earth and takes on human form. Sci-fi is not a genre I watch much so I thought I would try this series out. I found it to be hilarious with quirky characters and great writing. it's light hearted for the most part so I can watch it and get a good laugh. Doing new things regularly is a great way to get out of your comfort zone and keep your mind engaged and active. Would I play pinochle again, yep! I would also donate platelets again.

Welcome back to "Ditch the Labcoat," where today we debunked heart health myths with the remarkable Dr. Michael Ward. Did you know stress can literally break your heart? Dr. Ward broke down the realities of Takatsubo cardiomyopathy, stressed the importance of timely intervention in heart attacks, and shared his insights on the Mediterranean diet for cardiac wellness. Plus, we got a glimpse into the high-stakes world of interventional cardiology—straight from the operation room. Stay heart-smart and catch the full episode for a deep dive into the art and science of keeping your ticker ticking! Remember, a healthy heart is a healthy start. Don't miss it!00:00:03 Understanding Takotsubo Cardiomyopathy and Broken Heart Syndrome with Dr. Michael WardDr. Mark Bonta discusses Takotsubo cardiomyopathy, also known as broken heart syndrome, with Dr. Michael Ward. They explore how the condition is often triggered by emotional stress, such as the loss of a loved one, leading to acute heart failure.00:01:03 Discussion on the Heart as a Muscle and Cardiac ConditionsDr. Michael Ward discusses the heart as a muscle that pumps and the various cardiac conditions patients may face, such as heart attacks, heart failure, and heart rhythm problems. The conversation emphasizes the importance of understanding the basic function of the heart for better management of cardiac health.00:02:26 Discussion with Dr. Michael Ward on Interventional Cardiology and Hypertrophic CardiomyopathyDr. Michael Ward is an expert in interventional cardiology who helps people prevent and recover from heart-related issues. He also focuses on hypertrophic cardiomyopathy, a genetic condition affecting the heart. With a background in both medicine and research, he is a valuable asset at Western University in London, Ontario.00:03:50 Interview with Dr Michael Ward, Interventional CardiologistDr. Michael Ward, an interventional cardiologist with both an MD and a PhD, discusses his background in cell-based gene therapy and his interest in cardiovascular medicine. He shares insights on heart health, the importance of vacations for mental health, and his balanced lifestyle.00:07:18 Insight into the Fascinating Aspects of the Heart from an Interventional Cardiology PerspectiveDr Mark Bonta, an interventional cardiologist, shares his perspective on the intricate nature of the heart, highlighting how it responds to various stimuli and stressors. He emphasizes the role of the cardiovascular system in determining life and death outcomes and the potential for improving quality of life through cardiology interventions.00:11:14 Discussion on Interventional CardiologyDr. Mark Bonta discusses their work in interventional cardiology, including responding to emergencies like heart attacks and performing procedures in the catheterization laboratory. They describe the challenges faced by patients with heart conditions and the range of cases they handle.00:13:26 Understanding Cardiovascular System with Dr. Michael WardDr. Michael Ward talks about atherosclerosis as the accumulation of plaque in the arteries, which can lead to heart issues like angina and heart attacks. The discussion also touches on the difference between chronic accumulation of plaque and acute blockages causing heart attacks.00:18:01 Understanding Acute Heart Attacks and Plaque Ruptures in ArteriesAcute heart attacks can occur when plaque ruptures inside an artery, leading to a clot that blocks the artery and causes the heart attack. Platelets play a crucial role in responding to the rupture and forming clots to heal the affected area.00:19:44 Importance of Timely Intervention in Heart AttacksDuring a conversation between Dr. Mark Bonta and Dr. Michael Ward Interventional Cardiology, they discussed the critical importance of timely intervention in heart attacks. Dr. Bonta mentioned that when a heart attack occurs, time is of the essence as the muscle of the heart is deprived of blood flow. Historically, patients were given aspirin and blood thinners but no interventional procedures were done immediately.00:21:20 Advanced Cardiac Care Protocols in CanadaIn Canada, there are advanced protocols in place for managing ST-elevation myocardial infarction (STEMI) cases, including direct ambulance transportation to hospitals with cath labs. Time is crucial in treating cardiac emergencies to minimize heart muscle damage.00:23:51 Patient Experience in the Cath Lab: What to ExpectThe patient experience in the cath lab involves inserting a needle with a wire into their arteries, either through the wrists or groin. Patients may not feel much during the procedure, but there might be some sensations of discomfort or awareness of the procedure taking place.00:26:56 Understanding the Process of Opening Blocked Heart VesselsIn the conversation between Dr Mark Bonta and Dr Michael Ward Interventional Cardiology, they discuss the process of opening blocked heart vessels during angioplasty procedures.

Click this link now In today's episode: Platelets, also known as thrombocytes, are small cell fragments in the blood that play a crucial role in the body's ability to stop bleeding and form blood clots. When there is an injury or damage to blood vessels, platelets become activated and adhere to the site of injury, where they release various substances to initiate the blood clotting process. This is a normal and essential part of the body's response to injury, preventing excessive bleeding. However, when platelets become overactivated, it can lead to problems, especially in the context of cardiovascular diseases (CVD). Platelet stickiness refers to the tendency of platelets, small blood cells, to adhere to each other or to the walls of blood vessels upon activation. Normally, platelets circulate in the blood in an inactive state. However, when there's injury or damage to blood vessels, platelets become activated, changing shape and releasing chemical signals that prompt them to stick together (aggregate) and adhere to the damaged vessel walls. This adhesive property of platelets is crucial in the process of hemostasis, which is the body's mechanism to prevent excessive bleeding. When blood vessels are injured, platelets adhere to the site of injury, forming a plug to seal the damaged area. This initial platelet aggregation is followed by the coagulation cascade, involving the formation of a blood clot to further stem the bleeding. There are 7 new secrets you will learn about reducing platelet stickiness in this lesson. While platelet stickiness is essential for preventing excessive bleeding, abnormal or excessive platelet aggregation and adhesion can lead to issues like thrombosis, where blood clots form within blood vessels without an injury or obstruction, potentially causing blockages and leading to conditions such as heart attacks or strokes. Therefore, the regulation of platelet stickiness is crucial for maintaining proper hemostasis and preventing abnormal clotting.
Platelets are the part of blood that help control bleeding by collecting and clotting at the site of an injury. However, the role that platelets play in immune response is emerging and exciting, and Bloodworks Research Institute is privileged to now be home to one the most brilliant minds investigating this relationship: Dr. Li "Amily" Guo. Bloodworks 101 producer Helen Pitlick sat down with Dr. Guo to learn about her research—and the curiosity that drives her.
Dr. Moises Auron discusses about his high value approach to transfusion of blood products: PRBC, FFP, and Platelets.
Maria Turner from the Roswell Park Donor Center on the need for blood and platelets
While it's true that the majority of people will have a run-in with some kind of cancer in their lifetime, we need to remember that no 2 cancers are the same, and your overall metabolic health has a huge impact on how your body will manage the cancer and what your survival rates will be, plus which treatment path you should go down. To test your body's current metabolic health status when dealing with cancer, there's a number of simple blood tests you can run that will show how well (or poorly) your body is handling the tumor load. You'll want to run the following tests: CBC and specifically look at WBC, Platelets, and the Neutrophil to Lymphocyte ratio Comprehensive Metabolic Panel - Creatinine, Liver enzymes, Alkaline Phosphatase Inflammatory markers - LDH, ESR, hs-CRP

Platelets -- the part of blood that helps control bleeding -- are lifesaving for cancer patients, those receiving organ or bone marrow transplants, victims of trauma, and patients undergoing open-heart surgery. But donated platelets have a shelf-life of only 5-7 days. What if we could extend the life of platelets? What if modern platelet use is based on outdated assumptions? Dr. Moritz Stolla of Bloodworks Research institute wants to find out.
Chief Medical Officer at Northwestern Medicine Central DuPage Hospital Dr. Kevin Most joins the Steve Cochran Show to discuss whether it's necessary to take time off from work for a head cold, the reasons behind the blood shortage in the United States, and why people often delay seeking medical attention until they perceive something as 'extremely wrong.' Dr. Kevin Most's Steve Cochran Show Notes: October is Breast cancer Awareness Month Breast cancer is the 2nd most common cause of Cancer among women, second only to skin cancer It makes up 30% of all new female cancers Annual cases in the US are approaching 400,000 a year. 43,000 women will die from breast cancer in the US this year Median age for breast cancer detection is 62 years old, this means that 50% of new cases of breast cancer occur in women under 62 years old. Women have a 1 in 8 chance of developing breast cancer at some time in their lives Incidence has increased slightly each year, better diagnosis? More awareness? Or environmental Breast cancer is the second leading cause of cancer death in women (lung cancer is the leading cause of cancer death in women) Breast cancer death rates have declined since 1989- results of finding cancer earlier, better treatments, screening awareness Risk factors include- alcohol consumption, obesity, sedentary lifestyle, women who have not had children, not breast feeding, hormonal therapy post menopause In May of 2023- recommendations changed to recommend that annual mammograms start at age 40 Mammogram timing at Covid and Flu shots – because of the immune response and the possible swelling of lymph nodes with the shots, many are recommending completing a screening mammogram 4-6 weeks following the vaccine The reason for this is the inflamed lymph nodes may lead to a false positive reading on a mammogram and lead to additional testing that in reality is not needed The best option is get the mammogram and then follow up with the annual vaccines, the timing should work Blood shortage- Red Cross provides about 40% of all blood in the US Red Cross has seen donations drop 25% over the past few months and is now at a critical level Versiti Blood center of Illinois is a large donation company in the suburbs with many sites to donate Donations have declined by 25% since August- reasons include natural disasters, vacations, back to school Red Cross is pushing for allowing high schools to do blood drives again, these were stopped during the Covid pandemic This halt has not only impacted the amount of blood collected but also is seen as missing an opportunity to get new donors in line for continued donations People can donate blood every 8 weeks When you donate blood it is used in different ways- Red Blood Cells can be used for up to 30 days, Platelets which help with clotting last 5 days, Plasma which has clotting factors last up to a year as it is able to be frozen Are the fall drinks good for you Starbucks, Peet's , Dunkin Donuts, are now pushing the Fall Drinks, but do you know how they impact your nutrition Pumpkin Spice Latte 470 calories, 16g of fat and 60g of sugar – Venti or large size Perspective 2,000- 2,500 calories a day total is a goal. 60 g of Fat a day is a goal, 24 grams of sugar is a goal Christmas is right around the corner – Peppermint Mocha with whole milk- Venti – 550 calories, 22 grams for fat, 66 grams of sugar We know coffee has some great health benefits including antioxidants, decreases the risk of diabetes, decreases the risk of some cancers and may protect you from dementia, decreases the risk of depression So, Not saying stop drinking coffee just understand the health impact when adding all the flavors and sweeteners. Full Body MRI's- status symbol? Realistic- Kim Kardashian, Paris Hilton, Cindy Crawford touting these? Some celebrities are promoting a full body MRI done by a company Prenuvo, saying it is life saving Some celebrities are offering discount codes The scans cost $2,500 and are not covered by insurance, The company started in 2018, touts the scan as preventive and looks for illnesses before they are detected by traditional screening. They have 8 locations across North America and will be opening 12 more. There is one in Chicago The company is pushing this test as proactive instead of reactive You can go on their website and look at the different types of cancer that their scan may be able to identify Currently each type of cancer has some screening process, when taken as a group of tests this can be cumbersome and expensive Consider colonoscopy, mammograms, PSA tests, PAP tests these are all tests we use to identify cancers thru screening, time consuming and fragmented, but in most cases still the “gold standard” for screening. Some cancers have no screening tests currently, like pancreas, ovarian, brain, kidney, and liver. While MRI would certainly identify some of these tumors at an early stage, the MRI results are not always as accurate as one would hope and thus lead to additional testing and risky procedures which may not be appropriate (biopsies) Currently not supported by most physicians We certainly do not have enough scanners in the US if this was going to be considered Could it help with screening for those who have put off screening? Could it identify a cancer early in the lungs, brain or pancreas that may be lifesaving, or at least life extending? The company recommends these scans every two years Is this a technology that is just ahead of its time and will be the gold standard in the future???? With so few sites, it does come down to those who can afford the test. The test may fill the needs of a population who is looking for more information about their risk for illnesses, like genetic testing See omnystudio.com/listener for privacy information.
This may be our most fascinating podcast ever! We are joined by the Co-Founder of Rion, Inc., researcher and pioneer of regenerative medicine, and Cardiologist at the Mayo Clinic, Atta Behfar, MD, PhD. We're also joined by Saranya Wyles, MD, PhD, Associate Professor of Dermatology, Program Director of Clinical Regenerative Medicine Education at Mayo Clinic and the Principle Investigator for Rion Aesthetic's flagship product, (plated)™. Dr. Behfar spent several years in the initial stages of research getting a deep understanding of what influences cells to participate in wound healing. His research led him to find the major gap- communication- which is where exosomes come into play. They are the mechanism by which cells communicate with one another and make things happen in the body. Next, it was about finding the best communicators which led him and his research team to identify a particular group of platelet-derived exosomes that were specifically communicating about regeneration and repair. This was a true needle in a haystack endeavor, and thankfully it's paid off- it's propelled regenerative medicine in aesthetics to a whole new level. Several years later, his findings turned into Rion, Inc as he continued on with research focused on organ regeneration (eventually the heart), and as a byproduct, he found an invaluable application within aesthetics. Looking into the future, he discusses what is possible with injectable exosomes to supercharge what filler, toxin and biostimulators can do in the tissue. We won't need to just fill or relax wrinkles, but there is the potential to repair the tissue enough that it's no longer a concern. If Dr. Behfar is where it started, Dr. Wyles is how it's going. Not only is she an expert in regenerative medicine, but she's also a practicing Dermatologist. She is using exosome technology in her practice daily, and to hear her discuss the effectiveness and results she sees with (plated)™ is remarkable. She is using it as a primer for her patients before procedures, as their primary skincare product, and as a post-treatment wound-healing accelerant. While this is not a sponsored Rion Aesthetic's podcast, the results she's seeing clinically, not just in the lab, are cause for major kudos to the Rion Aesthetics research team! She's working on next steps toward future research involving hair growth, injectable exosomes and atopic dermatitis among other potential uses- all pending the FDA of course. She truly is the perfect intersection of where the research lab meets the treatment chair. We are definitely at the tip of the spear in regenerative medicine with this episode. It's rare to sit down with two of the best and brightest minds on the research front and get a solid breakdown of the science and the clinical application of something as novel as platelet-derived exosomes. In addition, Dr Wyles provides a checklist of sorts for you to consider before bringing exosomes into your practice. It's important to check things like donor quality, batch consistency, batch effectiveness, platelet or stem-cell derived, and to ask for the clinical research that is backing the product. We know Rion Aesthetics has no shortage of research available, and from the sound of what's next, they are only getting started!

This month on Episode 48 of Discover CircRes, host Cynthia St. Hilaire highlights three original research articles featured in the April 28th issue of Circulation Research. This Episode also includes a discussion between Dr Mina Chung, Dr DeLisa Fairweather and Dr Milka Koupenova, who all contributed to manuscripts to the May 12th Compendium on Covid-19 and the Cardiovascular System. Article highlights: Heijman, et al. Mechanisms of Enhanced SK-Channel Current in AF Chen, et al. IL-37 Attenuates Platelet Activation Enzan, et al. ZBP1 Protects Against Myocardial Inflammation Compendium on Covid-19 and the Cardiovascular System. Cindy St. Hilaire: Hi, and welcome to Discover CircRes, the podcast of the American Heart Association's journal, Circulation Research. I'm your host, Dr Cindy St. Hilaire, from the Vascular Medicine Institute at the University of Pittsburgh. Today, I'm going to be highlighting articles from our April 28th and May 12th issues of Circulation Research. I'm also going to have a chat with Dr Mina Chung, Dr DeLisa Fairweather and Dr Milka Koupenova, who all contributed to articles in the May 12th COVID Compendium. But before we have that interview, let's first talk about some highlights. The first article I want to present is titled Enhanced Calcium-Dependent SK-Channel Gating and Membrane Trafficking in Human Atrial Fibrillation. This article is coming from the University of Essen by Heijman and Zhou, et al. Atrial fibrillation is one of the most common forms of heart arrhythmia in humans and is characterized by irregular, often rapid heartbeats that can cause palpitations, dizziness and extreme fatigue. Atrial fibrillation can increase a person's risk of heart failure, and though treatments exist such as beta blockers, blood thinners and antiarrhythmia medications, they can have limited efficacy and side effects. A new family of drugs in development are those blocking small-conductance calcium-activated potassium channels called SK channels, which exhibit increased activity in animal models of AF and suppression of which attenuates the arrhythmia. In humans however, the relationship between SK channels and atrial fibrillation is less clear, at least in terms of SK channel mRNA levels. Because mRNA might not reflect actual channel activity, this group looked at just that and they found indeed that channel activity was increased in cardiomyocytes from atrial fibrillation patients compared to those from controls even though the mRNA and protein levels themselves were similar. The altered currents were instead due to changes in SK channel trafficking and membrane targeting. By confirming that SK channels play a role in human atrial fibrillation, this work supports the pursuit of SK channel inhibitors as possible new atrial fibrillation treatments. The next article I want to present is titled IL-37 Attenuates Platelet Activation and Thrombosis Through IL-1R8 Pathway. This article comes from Fudan University by Chen and Hong, et al. Thrombus formation followed by the rupture of a coronary plaque is a major pathophysiological step in the development of a myocardial infarction. Understanding the endogenous antithrombotic factors at play could provide insights and opportunities for developing treatments. With this in mind, Chen and Hong, et al. investigated the role of interleukin-1 receptor 8, or IL-1R8, which suppresses platelet aggregation in mice, and of IL-37, a newly discovered human interleukin that forms a complex with IL-1R8 and is found at increased levels in the blood of patients with myocardial infarction. Indeed, the amount of IL-37 in myocardial infarction patients negatively correlates with platelet aggregation. They also show that treatment of human platelets in vitro with IL-37 suppresses the cell's aggregation and does so in a concentration-dependent manner. Moreover, injection of the protein into the veins of mice inhibits thrombus development and better preserves heart function even after myocardial infarction. Such effects were not seen in mice lacking IL-1R8. This suggests IL-37's antithrombotic action depends on its interaction with the receptor. Together, the results suggest IL-37 could be developed as a antithrombotic agent for use in MI patients or indeed perhaps other thrombotic conditions. The last article I want to present before our interview is titled ZBP1 Protects Against Mitochondrial DNA-Induced Myocardial Inflammation in Failing Hearts. This article is coming from Kyushu University and is by Enzan, et al. Myocardial inflammation is a key factor in the pathological progression of heart failure and occurs when damaged mitochondria within the stricken cardiomyocyte release their DNA, triggering an innate inflammatory reaction. In a variety of cells, DNA sensors such as Z-DNA-binding protein 1 or ZBP1 are responsible for such mitochondrial DNA-induced inflammation. In theory then, it's conceivable that therapeutic suppression of ZBP1 might reduce myocardial inflammation in heart failure and preserve function. But as Enzan and colleagues have now discovered to their surprise, mice lacking ZBP1 exhibited worse, not better heart inflammation and more failure after induced myocardial infarction. Indeed, the test animals' hearts had increased infiltration of immune cells, production of inflammatory cytokines and fibrosis together with decreased function compared with the hearts of mice with normal ZBP1 levels. Experiments in rodent cardiomyocytes further confirmed that loss of ZBP1 exacerbated mitochondrial DNA-induced inflammatory cytokine production while overexpression of ZBP1 had the opposite effect. While the reason behind ZBP1's opposing roles in different cells is not yet clear, the finding suggests that boosting ZBP1 activity in the heart might be a strategy for mitigating heart inflammation after infarction. Cindy St. Hilaire: The May 12th issue of Circulation Research is our COVID compendium, which consists of a series of 10 reviews on all angles of COVID-19 as it relates to cardiovascular health and disease. Today, three of the authors of the articles in this series are here with me. Dr Mina Chung is a professor of medicine at the Cleveland Clinic. She and Dr Tamanna Singh and their colleagues wrote the article, A Post Pandemic Enigma: The Cardiovascular Impact of Post-Acute Sequelae of SARS-CoV-2. Dr DeLisa Fairweather, professor of medicine, immunology and clinical and translational science at the Mayo Clinic, and she and her colleagues penned the article, COVID-19 Myocarditis and Pericarditis. Dr Milka Koupenova is an assistant professor of medicine at the UMass Chan School of Medical and she led the group writing the article, Platelets and SARS-CoV-2 During COVID-19: Immunity, Thrombosis, and Beyond. Thank you all for joining me today. DeLisa Fairweather: Thank you so much for having us. Mina Chung: Thank you. Milka Koupenova: Thank you for having us, Cindy. Cindy St. Hilaire: In addition to these three articles, we have another seven that are on all different aspects of COVID. Dr Messinger's group wrote the article, Interaction of COVID-19 With Common Cardiovascular Disorders. Emily Tsai covered cell-specific mechanisms in the heart of COVID-19 patients. Mark Chappell and colleagues wrote about the renin-angiotensin system and sex differences in COVID-19. Michael Bristow covered vaccination-associated myocarditis and myocardial injury. Jow Loacalzo and colleagues covered repurposing drugs for the treatment of COVID-19 and its cardiovascular manifestations. Dr Stephen Holby covered multimodality cardiac imaging in COVID, and Arun Sharma covered microfluidic organ chips in stem cell models in the fight against COVID-19. Cindy St. Hilaire As of today, worldwide, there have been over six hundred million individuals infected with the virus and more than six and a half million have died from COVID-19. In the US, we are about a sixth of all of those deaths. Obviously now we're in 2023, the numbers of individuals getting infected and dying are much, much lower. As my husband read to me this morning, one doctor in Boston was quoted saying, "People are still getting wicked sick." In 75% of deaths, people have had underlying conditions and cardiovascular disease is found in about 60% of all those deaths. In the introduction to the compendium, you mentioned that the remarkable COVID-19 rapid response initiative released by the AHA, which again is the parent organization of Circ Research and this podcast, if I were to guess when that rapid response initiative started, I would've guessed well into the pandemic, but it was actually March 26th, 2020. I know in Pittsburgh, our labs have barely shut down. So how soon after we knew of SARS-CoV-2 and COVID, how soon after that did we know that there were cardiovascular complications? Mina Chung: I think we saw cardiovascular complications happening pretty early. We saw troponin increases very early. It was really amazing what AHA did in terms of this rapid response grant mechanism. You mentioned that the RFA was announced, first of all, putting it together by March 26th when we were just shutting down in March was pretty incredible to get even the RFA out. Then the grants were supposed to be submitted by April 6th and there were 750 grants that were put together and submitted. They were all reviewed within 10 days from 150 volunteer reviewers. The notices were distributed April 23rd, less than a month out. Cindy St. Hilaire: Amazing. Mina Chung: So this is an amazing, you're right, paradigm for grant requests and submissions and reviews. DeLisa Fairweather: For myocarditis, reports of that occurred almost immediately coming out of China, so it was incredibly rapid. Cindy St. Hilaire: Yeah, and that was a perfect lead up to my next question. Was myocarditis, I guess, the first link or the first clue that this was not just going to be a respiratory infection? DeLisa Fairweather: I think myocarditis appearing very early, especially it has a history both of being induced by viruses, but being strongly an autoimmune disease, the combination of both of those, I think, started to hint that something different was going to happen, although a lot of people probably didn't realize the significance of that right away. Cindy St. Hilaire: What other disease states, I guess I'm thinking viruses, but anything, what causes myocarditis and pericarditis normally and how unique is it that we are seeing this as a sequelae of COVID? DeLisa Fairweather: I think it's not surprising that we find it. Viruses around the world are the primary cause of myocarditis, although in South America, it's the parasite Trypanosoma cruzi. Really, many viruses that also we think target mitochondria, including SARS-CoV-2, have an important role in driving myocarditis. Also, we know that SARS-CoV-1 and MERS also reported myocarditis in those previous infections. We knew about it beforehand that they could cause myocarditis. Cindy St. Hilaire: Is it presenting differently in a COVID patient than say those South American patients with the... I forget the name of the organism you said, but does it come quickly or get worse quickly or is it all once you get it, it's the same progression? DeLisa Fairweather: Yeah. That's a good question. Basically, what we find is that no matter what the viral infection is, that myocarditis really appears for signs and symptoms and how we treat it identically and we see that with COVID-19. So that really isn't any different. Cindy St. Hilaire: Another huge observation that we noticed in COVID-19 patients, which was the increased risk of thrombic outcomes in the patients. Dr Koupenova, Milka, you are a world expert in platelets and viruses and so you and your team were leading the writing of that article. My guess is knowing what you know about platelets and viruses, this wasn't so surprising to you, but could you at least tell us the state of the field in terms of what we knew about viruses and platelets before COVID, before Feb 2020? Milka Koupenova: Before Feb 2020, we actually knew that influenza gets inside in platelets. It leads to not directly prothrombotic events, but it would lead to release of complement 3 from them. That complement 3 would actually increase the immunothrombosis by pushing neutrophils to release their DNA, forming aggregates. In cases when you have compromised endothelium and people with underlying conditions, you would expect certain thrombotic outcomes. That, we actually published 2019 and then 2020 hit. The difference between influenza and SARS-CoV-2, they're different viruses. They carry their genome in a different RNA strand. I remember thinking perhaps viruses are getting inside in platelets, but perhaps they do not. So we went through surprising discoveries that it seemed like it is another RNA virus. It also got into platelets. It was a bit hard to tweak things surrounding BSL-3 to tell you if the response was the same. It is still not very clear how much SARS or rather what receptor, particularly when it gets inside would induce an immune response. There are some literature showing the MDA5, but not for sure, may be responsible. But what we found is that once it gets in platelets, it just induces this profound activation of programmed cell death pathways and release of extracellular vesicles and all these prothrombotic, procoagulant form of content that can induce damage around, because platelets are everywhere. So that how it started in 2019 and surprisingly progressed to 2021 or 2020 without the plan of really studying this virus. Cindy St. Hilaire: How similar and how different is what you observe in platelets infected, obviously in the lab, so I know it's not exactly the same, but how similar and how different is it between the flu? Do you know all the differences yet? Milka Koupenova: No offense here, they don't get infected. Cindy St. Hilaire: Okay. Milka Koupenova: Done the proper research. The virus does not impact platelets, but induces the response. Cindy St. Hilaire: Okay. Milka Koupenova: That goes back to sensing mechanism. Thank goodness platelets don't get infected because we would be in a particularly bad situation, but they remove the infectious virus from the plasma from what we can see with function. Cindy St. Hilaire: Got it. So they're helping the cleanup process and in that cleaning up is where the virus within them activates. That is a really complicated mechanism. Milka Koupenova: Oh, they're sensing it in some form to alert the environment. It's hard to say how similar and how different they are unless you study them hint by hint next to each other. All I can tell is that particularly with SARS-C, you definitely see a lot more various kinds of extracellular vesicles coming out of them that you don't see the same way or rather through the same proportion with influenza. But what that means in how platelet activates the immune system with one versus the other, and that goes back to the prothrombotic mechanisms. That is exactly what needs to be studied and that was the call for this COVID compendium is to point out how much we have done as a team. As scientists who put heads together, as Mina said, superfast response, it's an amazing going back and looking at what happened to think of what we achieved. There is so much more, so much more that we do not understand how one contributes to all of these profound responses in the organs themselves, such as myocarditis. We see it's important and that will be the problem that we're dealing from here on trying to figure it out and then long COVID, right? Cindy St. Hilaire: Yeah. Related to what you just said about the mechanism, this cleanup by the platelets or the act of cleaning up helps trigger their activation, is that partly why the antiplatelet and anticoagulant therapies failed in patients? Can you speculate on that? I know the jury's still out and there's a lot of work to be done, but is that part of why those therapies weren't beneficial? Milka Koupenova: The answer to that in my personally biased opinion is yes. Clearly, the antiplatelet therapies couldn't really control the classical activation of a platelet. So what I think we need to do from here on is to look at things that we don't understand that non-classically contribute to the thrombotic response downstream. If we manage to control the immune response in some way or the inflammation of the infection or how a platelet responds to a virus, then perhaps we can ameliorate a little bit of the downstream prothrombotic effect. So it's a lot more for us to trickle down and to understand in my personal opinion. DeLisa Fairweather: There is one thing that was really remarkable to me in hearing your experience, Milka, is that I had developed an autoimmune viral model of myocarditis in mice during my postdoc. So I've been studying that for the last 20 years. What is unique about that model is rather than using an adjuvant, we use a mild viral infection so it doesn't take very much virus at all going to the heart to induce it. I also, more recently, started studying extracellular vesicles really as a therapy, and in doing that, inadvertently found out that actually, the model that I'd created where we passage the virus through the heart to induce this autoimmune model, we were actually injecting extracellular vesicles into the mice and that's what was really driving the disease. This is really brought out. So from early days, I did my postdoc with Dr Noel Rose. If you've heard of him, he came up with the idea of autoimmune disease in the '50s. We had always, in that environment, really believed that viruses were triggering autoimmune disease and yet it took COVID before we could really prove that because no one could identify them. Here we have an example and I think the incidence rates with COVID were so high for myocarditis because for the first time, we had distinguished symptoms of patients going to the doctor right at the beginning of their infection having an actual test to examine the virus, knowing whether it's present or not, whether PCR or antibody test, and then being able to see when myocarditis happened. Cindy St. Hilaire: Yeah. I think one thing we can all appreciate now is just some of the basic biology we've learned on the backend of this. Actually, those last comments really led well to the article that your team led, Dr Chung, about what we call long COVID, which I guess I didn't realize has an actual name, post-acute sequelae of SARS-CoV-2 or PASC is the now more formal name for long COVID. But what is it? We hinted at it that there's these bits about autoimmune and things like that. What counts as long COVID? Mina Chung: Yeah. Our article was led by Tamanna Singh. She did a fantastic job of putting this together. We've had, and others, theorized that the huge palette of symptoms that you can experience post-COVID, they can affect all these organ systems with brain fog, these atypical chest pains, postural orthostatic tachycardia, a lot of palpitations, atrial fibrillation, many weakness and fatigue. To us, really, you can get GI symptoms. We've been very interested in, is this an autoimmune phenomenon directed against nerves and all those things. It's also very interesting because many of the non-COVID syndromes that existed pre-COVID like POTS and chronic fatigue syndrome and a lot of other syndromes are associated with autoantibodies. So that is a very interesting area to explore. Is there a persistence of viral fragments. Is there autoimmunity? Is it also a component of persistence of the damage from the initial infection? So it's an area that still needs a lot of work and a lot of work is going into it, but this is like a post or inter pandemic of itself, so hopefully we'll get more insights into that. Cindy St. Hilaire: Yeah, it's really interesting. I have a friend who has very debilitating long COVID and one of her doctors had said, "If I didn't know any better, I would just describe this as a autoimmune type X." What do we know, I guess, about the current hypothesis of the pathogenesis of PASC? Are there any prevailing theories right now as to why it's occurring? Is the virus still active or is it these domino effects that are leading to multi-organ collapse of some sort? Mina Chung: Yeah. In some people, persistent viral particles can be identified for months, but whether or not that's what's triggering it, it's hard to know. We see more autoimmune disease that's been reported and various antibodies being reported. So those are clearly processes to be investigated. The microthrombosis is still up there in terms of potentially playing a role in long COVID. Milka Koupenova: Mina, you probably know better because you see patients, but to all I have been exposed to, long COVID does not really have a homogeneous symptom presentation and then a few theories as to what may be going on in these patients. Not everybody has a microthrombosis. Not everybody have a D-dimer elevated, but some people do. Some people have, as you pointed out, these spectacularly profound brain fog. People can't function. It's probably your friend, Cindy, right? Cindy St. Hilaire: Yeah. Milka Koupenova: So one of the theories that I have been, from a viral perspective, very interested in is that a lot of the symptoms in certain individuals such as fatigue, brain fog, sensitivity to light and skin can very well be explained by a flare-up of Epstein-Barr virus that may be what SARS-CoV-2 somehow is inducing. I don't know, DeLisa, what your experience with long COVID is as a scientist. I hope only. But I would like to hear your perspective too because it's so heterogeneous and it is amazing what happens. DeLisa Fairweather: I have a very interesting perspective from a number of different directions. One, as I mentioned before, my long history with Dr Rose and I've written many articles theorizing how viruses could cause autoimmune disease. This has grown and really, I think this has been extremely revealing during COVID for many of those theories. One thing that I write about in the review for this article is that mast cells, from all the research I've done with myocarditis in our model, mast cells are central to what is driving everything. We show they're the first innate immune cell acting as an antigen-presenting cell, completely driving the response in a susceptible pattern. One of the things that's very important in autoimmune disease is both sex and race. I'd say one of the big weaknesses we have in myocarditis pre-COVID and post-COVID has been ignoring what's going on with race. In the United States, myocarditis is 90%, 95% white men that are under 50 years of age and most of the cases are under 40 or some of the ones really associated with sudden cardiac death are under 30. So it's very specific. I've been studying sex and race differences and we see those exact differences in our animal models. In animal models, whether you're susceptible or not depends on how many mast cells you have. Well, I've proposed from the beginning, looking, I've written a lot of different sex difference reviews looking at viruses and autoimmune disease with different autoimmune diseases and hypothesizing and really seeing that mast cells do a lot of the things we're talking about. They have all of the receptors, the whole group of them that have been related to SARS-CoV-2 so they can be activated or stimulated by the virus itself. They act as a antigen-presenting cell. They're critical in the complement pathway as well as macrophages. We see the dominant immune phenotype really being macrophages. Mast cells just are usually not counted anywhere. And of course, these receptors, a lot of them have to do with enzymes and things that are all related to mast cells pathways. Then how they activate the immune response and lead it towards the pathway that leads to chronic autoimmune disease with increased autoantibodies in females, mast cells are very different by sex. This has to do also when we talked in the Review about myocarditis and pericarditis. It's both those appearing. Although clinically, we have really boxed them as separate things, because there is some definite clinical pericarditis phenotypes that are different, myocarditis in animal models is always myopericarditis. It always then, in that outer pericardial areas where mast cells sit, they sit around the vascular area in most concentrated. So when they degranulate, we see inflammation coming in the vessel, but really concentrated with fibrosis there and along the pericardium. So that's very typical of what's going on. When we shift anything that shifts that, it changes whether you have more pericarditis or less pericarditis and the vascular inflammation by altering anything that affects the mast cells. I talk a little bit about in the review, I think there's only been a few recent things looking at it in COVID, but I think mast cells and certain susceptibility to autoimmune diseases that occur more often in women can really predispose.We need to pay more attention to mast cells and what they might indicate for all these pathways. Milka Koupenova: I think we should study the platelet mast cell access at this point. DeLisa Fairweather: Yes. Milka Koupenova: Because as you're talking about these sex differences, which is spectacular, these things to me are so mind-boggling how one, the infection itself would be more prevalent in men, but then long COVID is more prevalent in women. All of these things and why we understand so very little, what we found about a few years ago in the Framingham Heart Study in the platelets from those people is that all toll-like receptors are expressed at the higher level in women and they associate with different things between men and female. For instance, toll-like receptors in women will associate more with a prothrombotic response while in male with pro-inflammatory response. I think they grossly underestimate the amount of our sex differences from cell to cell. DeLisa Fairweather: It is, yeah. Mina Chung: One other thing that I learned about the sex differences from this compendium is Mark Chappell also notes, you mentioned TLR and TLR7 and ACE2 are X chromosome in an area that he says escapes X-linked inactivation. So it could very well be involved in further. DeLisa Fairweather: Further, yeah. And ACE2 is expressed more highly in male cells for what's been researched because of the sex difference in COVID, both the COVID infection Cindy St. Hilaire: So a variety of organ systems are impacted in patients with PASC, also referred to as long COVID, the lungs, the heart, the pancreas, the GI system, pretty much any system, the brain, nervous system. We've just been talking about the mast cell impact. I was really thinking in my head, well, the one thing that connects all of it is the vasculature. I'm a vascular biologist, so I have certain biases, I'm sure, but how much of the sequelae that we see is a function of vascular phenotypes? Milka Koupenova: I do think the vasculature is super important. It's clear that not all endothelial cells, for instance, will pick up the virus and respond to it. That's why you have this patchy breakage when you look at autopsies. Hence, platelets will respond according to what's local. That's why you find these micro thrombotic events at certain places. Why does it happen in each organ? How does the virus get to each organ to respond? Or is it just inflammation, but why is it in specific places? That's what we don't understand. That's where we need to go. Perhaps, as DeLisa points out, perhaps it's a lot more complicated than how we traditionally think of thrombosis. Actually, my personal bias, again 100% sure that it is a lot more complicated than the traditional mechanisms that we have understood, and that's where the immune system comes and autoimmunity perhaps stems from and they probably speak to each other, right? It's not just one thing. DeLisa Fairweather: Yeah. I think really, EVs are bringing lots of understanding. A lot of things we used to just think were maybe free-floating and the serum are inside EVs. I think that the immune response is perhaps even more specific than we ever thought and more regulated than we ever understood. When an EV comes through a cardiomyocyte, whether it's from the mitochondria or through a lysosome, is part of what goes into its outer membrane, something that tells the immune system that that came from the heart, so it knows to go. This will solve a lot of our questions with autoimmune disease if it's very specific like that. It doesn't just have to be the release of free-floating cardiac myosin. We know cardiac myosin is the driver of the autoimmune response in myocarditis, but they're probably much more fine-tuned. Cindy St. Hilaire: Yeah. I just would love to end with hearing from each of you. You each have your own domain of specialty. If I gave you a massive pot of money, what would be the question you would want to tackle? What's the gap you would love to answer? Milka Koupenova: We still don't understand specifically what kind of vesicles are coming out, what are their contents in addition to those vesicles. We don't understand. When it comes to platelets, what comes from their granules? We see these breakages of the membrane. Those are non-granule proteins, and non-granule proteins, they serve as dangerous associated molecular pattern signals and can be profoundly inflammatory to the surrounding environment, can be procoagulant. What are those? How are they affecting the surrounding environment? Ultimately, why is there a microthrombi? Why is there not a profound thrombosis everywhere? Thank goodness there isn't, but why isn't? That's what I would do with my money. DeLisa Fairweather: I think I would do something very similar. All of our research in our animal model, on the one side, we are looking in this viral myocarditis animal model and finding the EVs that come from that are driving myocarditis. On the other hand, we're using EVs that come from healthy human plasma or fat, and we're seeing a profound downregulation of everything if you give it early and we're trying to see how late you can give it and still get an effect. So looking at those and really understanding the components in the context of COVID and COVID vaccines to understand those components, I really think that's the future of where we're going to find what's causing disease and also how we can find therapies. They may be able to reverse this. Mina Chung: Yeah, I'm interested very much in the autoimmunity and the autoantibodies that are and how they may react with those microthrombi. Perhaps there's autoantibodies within a lot of that material. We're looking at using human and pluripotent stem cell-derived cell models to study the effects of those. That is what I would use our money for.

We used to say that you can save three lives with each donation because whole blood can be divided into red cells, platelets, and plasma. This just isn't the case anymore, and that's actually a good thing for local patients and non-profit blood centers like Bloodworks. That's because we now collect 100% of our platelets from apheresis. Vicki Finson and Russ Juntenen in our Blood Services department explain why.
