Venous thromboembolism (VTE), which includes deep vein thrombosis and pulmonary embolism, is responsible for 9–30% of pregnancy-related mortality in high resource countries and remains a significant, increasing cause of severe maternal morbidity. Peripartum, 50% of VTE events occur in the postpartum interval, which has a 6-fold higher risk compared to antepartum. There is wide variation in LMWH pharmacological postpartum prophylaxis guidance. The RCOG, for example, recommends 10 days of LMWH for all postop CS patients unless it was elective, and additional risk factors exist. The ACOG uses a more selective approach. However, on Jan 16, 2025, a new multicenter retrospective study from the US is raising questions about the efficacy of postpartum VTE pharmacologic therapy. Is there really no need for pp VTE pharmacologic therapy? Or does the answer lie in the reality of VTE as a “low frequency, high acuity” event? Listen in for details!

Everyone understands that VTE (DVT and/or VTE) requires life-saving anticoagulation. That's simple. No controversy there. But what about pregnancy-associated superficial thrombophlebitis (AKA superficial venous thrombosis) in an extremity? Does that need anticoagulation? We have been traditionally taught that superficial venous issues are benign and do not require LMWH. Is that correct? The answer is NOT as straightforward as you would think. In this episode, we will review the 2018 ASH guidelines and contrast them to the 2022 published consensus statement from the Balkan Working Group. Plus, we will highlight a May 2023 Danish population based study from the Lancet Hematology that reminds us that superficial venous disease is not always benign in its course. Listen in for details,

The SMFM, ACOG and RCOG all recommend screening for Antiphospholipid Antibody Syndrome (APS) in women with Recurrent Pregnancy Loss (RPL). However, once identified, there has been controversy historically regarding the best TIME to initiate low dose aspirin and prophylactic LMWH. The main controversy regarding this is whether to begin treatment before a confirmed pregnancy, right after a positive pregnancy test, or only after an ultrasound confirms a viable fetus; with some studies suggesting potential benefits from starting earlier, while others debate the optimal timing due to lack of conclusive evidence and potential risks associated with early anticoagulation. Nonetheless, we DO HAVE current guidance here to make an evidence-based plan of care for these patients. In this episode, we will summarize a recent Clinical Expert Series from the ACOG (May 2024) and the RCOG (June 2023). PLUS, we will highlight some persistent controversies surrounding APS and RPL.

2:38  Labiotech news4:23  APSFA20:59 University of MichiganJune is Antiphospholipid Syndrome (APS) Awareness Month. APS is a rare autoimmune disorder in which the body recognizes certain normal components of blood and/or cell membranes as foreign substances and produces antibodies against them. There are two known forms. APS may occur in people with systemic lupus erythematosus, other autoimmune disease, or in otherwise healthy individuals.APS is also referred to as APLS or APLA in the U.S., and formerly Hughes Syndrome or Sticky Blood in the U.K.On the podcast this week, we spoke with Tina Pohlman, who suffers from APS, and who is president of the APSFA, about the disease and the organization.The APS Foundation of America, Inc. (APSFA) was founded in 2005, and is the only U.S. nonprofit health agency dedicated to bringing national awareness to APS, a major cause of multiple miscarriages, thrombosis, young strokes and heart attacks. The APSFA's Medical Advisory Team includes nationally & internationally recognized experts on Antiphospholipid Syndrome.We also had a conversation with APS researcher Dr Jason Knight, Marvin and Betty Danto Research Professor of Connective Tissue Research and Associate Professor, Division of Rheumatology at the University of Michigan.Current APS trialsThere are currently several clinical trials being undertaken with respect to APS. University Hospital, Clermont-Ferrand, France, is looking to assess the effect of injectable anticoagulants (unfractionated heparin (UFH), low molecular weight heparins (LMWH), fondaparinux, danaparoid, and argatroban) on lupus anticoagulant testing assays over broad anti-Xa activity ranges and to establish their potential for causing false-positive or false-negative results.David Ware Branch, from the University of Utah, is also undertaking a trial with results expected in 2024. The treatment trial is evaluating the addition of an anti-tumor necrosis factor-alpha drug,certolizumab, compared to the usual treatment (a heparin agent and low-dose aspirin) in pregnant women with APS and repeatedly positive tests for lupus anticoagulant (LAC) to determine if this regimen will improve pregnancy outcomes. All enrolled patients will receive certolizumab, and pregnancy outcomes will be compared to those of women with APS and repeatedly positive tests for LAC enrolled in a previous study by the investigators.Another study, in China, also with results anticipated in 2024, is being run by Zhang Lei. The study aims to evaluate the safety and efficacy of zanubrutinib in the treatment of APS with secondary thrombocytopenia in 10 patients.The University of Turin in Italy is sponsoring BLAST (belimumab antiphospholipid syndrome trial), which is expecting to see results in 2025. BLAST aims to evaluate the safety and tolerability of belimumab for up to 24 months in patients with persistent aPL positivity and clinical features attributable to aPL that are resistant to warfarin and/or heparin.

VTE is a common cause of morbidity and mortality, and people with cancer are at a higher risk for developing VTE than people without cancer.Cancer is known to increase the risk of VTE, with cancer patients having a four to seven times increased risk of developing VTE. These patients also have a higher risk of recurrent VTE and of bleeding.Previous studies such as SELECT-D and CONKO-11 demonstrated that changing from a low molecular weight heparin (LMWH) to XARELTO was associated with a reduction in risk of recurrent thrombosis and improved patient satisfaction.Knowledge GateKnowledge Gate Group provides a key opinion leader online platform.

Pearls- Pregnancy and Anticoagulation Pregnancy is a hypercoagulable state. Pregnancy-associated VTE is a leading cause of maternal morbidity and mortality.The use of anticoagulation requires a balance between the risks and benefits to the mother and her fetus.The agent of choice for anticoagulation during pregnancy depends on the indication, pre-pregnancy dose of vitamin K antagonist (VKA), and the trimester of pregnancy. For instance, patients with mechanical heart valves, warfarin is generally recommended in the first trimester if the daily dose is less than 5 mg and as the first option for all patients with mechanical valves in the 2nd and 3rd trimester. Use of direct oral anticoagulants (DOACs) has not been systematically studied, they do cross the placenta and their safety remains untested.Warfarin crosses the placenta but is not found in breast milk. LMWH does not cross the placenta and is not found in breast milk. Thus, both these agents can be used by a lactating mother. Quatables - Pregnancy and Anticoagulation “[We] can't highlight enough that good communication and documentation is vital in such situations” says Dr. Berlacher while discussing the role of a multidisciplinary team including cardiologists, obstetricians and fetal medicine physicians in taking care of a pregnant patient on anticoagulation. “What I love about cardio-obstetrics is that we really can help women in a time that is so important in their life…this is one of the most memorable times in their life..” says Dr. Berlacher when asked what makes your heart flutter about cardio-obstetrics. “Knowledge is power...not just for providers, but also for the patients” says Dr. Berlacher emphasizing the importance of clear communication between physicians and patients. Show notes - Pregnancy and Anticoagulation 1. What makes pregnancy a hypercoagulable state? Pregnancy is a hypercoagulable state associated with higher risk of thromboembolic phenomenon. The three components of Virchow's triad: hypercoagulability, stasis, and endothelial injury are all present during pregnancy. This leads to a 5-fold increased risk of venous thromboembolism (VTE) during pregnancy that persists for 12 weeks postpartum. The risk for VTE seems to be highest in the first 6 weeks postpartum, with a higher prevalence of clot in the left lower extremity.There are additional risk factors for developing VTE in the postpartum period besides pregnancy itself, and this includes but is not limited to preeclampsia, emergent c-section, hypertension, smoking, and postpartum infection.Choosing anticoagulant therapies during pregnancy involves a fine balance between the risks and benefits to both the mother and fetus. A multidisciplinary team involving the obstetrician, cardiologist, and maternal-fetal medicine team is critical to guide anticoagulation in pregnanc...

In this episode, we discuss the recently published major updates in the 9th edition of the anticoagulation guidelines from CHEST. These new recommendations range from initiation of therapy, secondary prevention, and management of post-thrombotic syndrome. Key Concepts Among patients with cancer-associated VTE, DOACs are preferred over low molecular weight heparins (LMWH) EXCEPT in patients with GI cancers. The preferred anticoagulant in those with GI cancers is either LMWH or apixaban. Among patients with antiphospholipid antibody syndrome, warfarin (INR goal 2-3) is preferred over DOAC therapy. In the extended phase of treatment (secondary prevention after 3 months of treatment), lower anticoagulant doses should be used (such as apixaban 2.5 mg BID or rivaroxaban 10 mg daily). In patients with a DVT, IVC filters should only be used when anticoagulation therapy is contraindicated. IVC filters reduce the risk of PE but do not alter the risk of DVT extension or future DVTs. Compression stockings are not recommended for prevention of post-thrombotic syndrome nor for recurrent DVT prevention.

This is not to be confused with the fact that this agent provides a very good modality to providing anticoagulation and has very specific uses, but in the real world setting, IV infusion of this agent causes issues with the quality of anticoagulation achieved. We discuss how there may be better alternatives specifically low molecular weight heparin (LMWH) when it comes to use cases in stroke. Anticoagulating a patient with acute stroke is always a challenging topic, and there are nuances to be considered, to reduce the risk of hemorrhage, and therefore we looked back at the use of unfractionated heparin infusion in stroke and talk about how some considerations are very important to keep in mind.

Valeo Pharma is already a successful, revenue generating, small cap Canadian pharmaceutical company that acquires the Canadian rights to commercialized drugs in other parts of the world that don't have Canada on their radar as a target market. This "in-license" business model is ingenious because it means ZERO developmental or clinical risk, which is the downfall of most small cap pharma companies. This model has resulted in the following success: 2020 net revenues of $7.5 million 2021 is expected to double to $15 million Commercializing Novartis Asthma Therapies In Canada Closed $6.6 Million Financing With Insiders Taking ~ 40% If that was all Valeo had, most investors would be happy to sit back and watch the Company grow. But then came Redesca. We are going to save you the science and tell you that Redesca belongs to a class of anticoagulant medications (blood thinners) called LMWH. The size of the Canadian LMWH market is over $200M per year and Valeo believes they can capture 15-20% of this market. If you're doing back of napkin math, that equates to $30,000,000 - $40,000,000 per year in revenues. But how does a new product capture that much market share? Glad you asked because we asked CEO Steve Saviuk the same question. Competition is tough in all markets and they don't let someone take 15-20% market share without one hell of a fight. Saviuk agreed and gave the following 3 reasons: 1. Redesca has an 8-year international track record of safety and efficacy. It is already well known 2. Redesca is flat out cheaper, which is music to the ears of Provincial Health Ministries whose budgets have been stretched to the max this year no thanks to COVID-19. Vaelo is so confident that it stated "This is great news for the Canadian healthcare system .... and is expected to help provide significant savings to provincial healthcare systems." More than just lip service, $VPH just announced that Redesca is now listed on the Ontario Public Drug Program, which means the government will cover its costs for all public use. Moreover, $VPH expects additional Provinces to follow. If you love revenue generating, growing and blue sky potential small cap companies, then this Valeo interview is a must watch.

In today's episode we discuss: —Adjusting Practice During COVID-19: A team of cardiologists and pharmacists from hospitals in Shanghai and Wuhan, China assessed the association between mortality in hospitalized COVID-19 patients (n=535) and low molecular weight heparin (LMWH) use between January 26-March 26, 2020. They found overall adjusted odds ratio for mortality was lower in the LMWH-users vs non-users (0.20; 95% CI, 0.09-0.46), specifically in severe (0.08; 95% CI, 0.01–0.62) and critically ill cases (0.32; 95% CI ,0.10–0.996). Authors suggest LMWH appears correlated with a survival benefit in hospitalized COVID-19 patients, especially those severely and critically ill. --- Support this podcast: https://anchor.fm/covid19lst/support

Today I do a quick review of the COVID-19 thrombosis literature from the last year to try to answer some of the following questions: Why does COVID-19 cause thrombosis? How many patients with COVID-19 develop thrombotic complications? Why do patients with COVID-19 on VTE prophylaxis still develop blood clots? Should we use intermediate dosing of anticoagulation for prophylaxis? What about full dose therapeutic anticoagulation (no!) What do the guidelines say? Lots of papers:JAMA IM Review Autopsy Findings and VTE in Patients with COVID-19Klok et al Helms et alShah et alPiazza et alPorfidia et alKunutsor et alDutt et alStessel et alParanjpe et alFraisse et alMusoke et alPatel et alISTH GuidelinesACCP GuidelinesTake home points:COVID-19 is associated with an elevated risk of thrombosis. Observational data suggests that ICU patients are likely to develop thrombotic complications even on standard VTE prophylaxis. This number seems to be round 25%. Ward patients are also at higher risk (around 8-9%). Critically ill patients commonly develop heparin resistance, and this may partially explain why some patients with COVID develop thrombotic complications despite prophylaxis. Some have suggested intermediate dosing of anticoagulation for prophylaxis, but there are no randomized controlled trials published at this time, and observational data are limited. Some have suggested therapeutic dosing of anticoagulation for critically ill patients, but observational data show high rates of bleeding and other complications, and the three largest randomized controlled trials have stopped enrolling critically ill patients into the therapeutic anticoagulation arm due to safety concerns and futility. Some have suggested targeting a certain anti-Xa activity level, but no one really knows what that should be, and there aren’t any guidelines recommending it. ISTH and ACCP have both put out guidelines which are overall pretty similar.Make sure your patient has VTE prophylaxis, preferably a LMWH, and keep an eye out for thrombotic complications so you can treat them in a timely manner.

Valeo Pharma is already a successful, revenue generating, small cap Canadian pharmaceutical company that acquires the Canadian rights to commercialized drugs in other parts of the world that don’t have Canada on their radar as a target market. This “in-license” business model is ingenious because it means ZERO developmental or clinical risk, which is the downfall of most small cap pharma companies. This model has resulted in the following success: $5.3M in revenues in the first 9 months of 2020 (ending July 31, 2020) 9 products currently in the market with an annual estimated peak sales of $40M/year 7 products in the pipeline with an annual estimated peak sales of $45M/year In fact, capital markets confidence is so high that Valeo secured $8.6M in financing in the last half of the year with: $6.9M Bought Deal financing at $1.20/shares A $1.7M Oversubscribed debenture (non-convertible) If that was all Valeo had, most investors would be happy to sit back and watch the Company grow. But then came Redesca. We are going to save you the science and tell you that Redesca belongs to a class of anticoagulant medications (blood thinners) called LMWH. The size of the Canadian LMWH market is over $200M per year and Valeo believes they can capture 15-30% of this market. If you’re doing back of napkin math, that equates to $30,000,000 – $60,000,000 per year in revenues. But how does a new product capture that much market share? Glad you asked because we asked CEO Steve Saviuk the same question. Competition is tough in all markets and they don’t let someone take 15-30% market share without one hell of a fight. Saviuk agreed and gave the following 3 reasons: 1. Redesca has an 8-year international track record of safety and efficacy. It is already well known 2.

Vaelo is so confident that it stated “This is great news for the Canadian healthcare system …. and is expected to help provide significant savings to provincial healthcare systems.” Well there you have it. Valeo is a great story. Watch the video. HOLD ON. THERE’S MORE … A LOT MORE In addition to being used primarily for treating and preventing deep vein thrombosis and pulmonary embolism, LMWH are also now increasingly used as a first line of defense tool in the fight against Covid-19. The World Health Organization’s (“WHO”) issued guidance regarding the prophylaxis use of LMWH to help prevent complications in the clinical management of severe acute respiratory infections when COVID-19 infection is suspected. The Canadian market for LMWH was already at a healthy $200M + per year when Valeo started down the Redesca path 4 years ago. Now it gets the added kicker of Redesca being a first line of defense to fight COVID-19. Now you have it. That’s the Valeo story as it applies to Redesca. There is a whole lot more to the story given their pipeline of products but we couldn’t cover it all in this great interview with CEO Steve Saviuk.

Episode 25: Autism [Music to start: Grieg’s Morning Mood (https://www.youtube.com/watch?v=-rh8gMvzPw0) The sun rises over the San Joaquin Valley, California, today is August 28, 2020. The Journal of the American Board of Family Medicine recently published the characteristics of primary care physicians (PCPs) associated with prescribing potentially inappropriate medication (PIM) for elderly patients. Medicare data from more than 100,000 PCPs was analyzed. The sample included specialists in family medicine, internal medicine, geriatrics and general practice. PCPs more likely to prescribe PIMs were on average older, male, DO, practicing in the South, and have a smaller Medicare patient panel. The study also found that PIM rates have been decreasing over time (1). So, don’t forget to review your Beers Criteria (2) when prescribing meds to your elderly patients. Cancer and VTE normally means low molecular weight heparin, LMWH aka Lovenox®, right? But direct oral anticoagulants (DOACs) are being used more frequently in patients with acute venous thromboembolism (VTE) and active cancer. Studies comparing their safety and efficacy with LMWH are limited. In a recent, randomized trial of 1170 patients with cancer and VTE, the DOAC apixaban resulted in similar rates of recurrent VTE when compared with the LMWH dalteparin (Fragmin®) (5.6 versus 7.9 percent) without any impact on major bleeding events. Apixaban is now considered a suitable alternative to LMWH for treatment of VTE in patients with active cancer (3). So, good point for Eliquis®.  [Music mixes with country Chris Haugen - Cattleshire - Country & Folk https://www.youtube.com/watch?v=WiYqHkH4Tnc&list=PLYo1YtVKirP-LAZ3AjpIiJNW9KIe1MJLw&index=7]Welcome to Rio Bravo qWeek, the podcast of the Rio Bravo Family Medicine Residency Program, recorded weekly from Bakersfield, California, the land where growing is happening everywhere.The Rio Bravo Family Medicine Residency Program trains residents and students to prevent illnesses and bring health and hope to our community. Our mission: To Seek, Teach and Serve. Sponsored by Clinica Sierra Vista, Providing compassionate and affordable care to patients throughout Kern and Fresno counties since 1971. [Music continues and fades…] ____________________________[MUSIC]“By three methods we may learn wisdom: First, by reflection, which is noblest; Second, by imitation, which is easiest; and third by experience, which is the bitterest.” –Confucius Spanish refrains don’t make sense, but here I have one to see if it makes sense: “Nobody learns on someone else’s brain”. It means, you learn better by experience. Dear residents, how do you want to learn wisdom? By reflection, by imitation or by experience?  Question number 1: Who are you?  This is Steven Saito. I am a former Navy doctor, having spent 6.5 years in the service primarily working out of a branch clinic having taken on a variety of additional duties including prior department head and senior medical officer. I am also a recent graduate from RBFM and have come back as faculty Tag line: I’m here to give you your weekly suppository of information. Relax and let it in.  Question number 2: What did you learn this week?  What I actually encountered was a need for follow up from podcast #9 vaccine hesitancy.  There were follow on questions for autisms and what we can be doing as primary care providers. I’m going to start with some basics of autism. Diagnostic Criteria The current DSM criteria states that a child must have persistent deficits in 3 areas of social communication/interaction and at least 2 of 4 types of restricted/repetitive behaviors.  It’s important to understand these criteria as not every child who has difficulty with eye contact falls on the spectrum. A: Areas of social communication and interactionDeficits in social-emotional reciprocity, ranging, for example, from abnormal social approach and failure of normal back-and-forth conversation; to reduced sharing of interests, emotions, or affect; to failure to initiate or respond to social interactions.Deficits in nonverbal communicative behaviors used for social interaction, ranging, for example, from poorly integrated verbal and nonverbal communication; to abnormalities in eye contact and body language or deficits in understanding and use of gestures; to a total lack of facial expressions and nonverbal communication.Deficits in developing, maintaining, and understand relationships, ranging, for example, from difficulties adjusting behavior to suit various social contexts; to difficulties in sharing imaginative play or in making friends; to absence of interest in peers.B: Restricted, repetitive patterns of behavior, interests, or activities, as manifested by at least two of the following, currently or by history (examples are illustrative, not exhaustive; see text):Stereotyped or repetitive motor movements, use of objects, or speech (e.g., simple motor stereotypes, lining up toys or flipping objects, echolalia, idiosyncratic phrases).Insistence on sameness, inflexible adherence to routines, or ritualized patterns of verbal or nonverbal behavior (e.g., extreme distress at small changes, difficulties with transitions, rigid thinking patterns, greeting rituals, need to take same route or eat same food every day).Highly restricted, fixated interests that are abnormal in intensity or focus (e.g., strong attachment to or preoccupation with unusual objects, excessively circumscribed or perseverative interests).Hyper- or hyporeactivity to sensory input or unusual interest in sensory aspects of the environment (e.g. apparent indifference to pain/temperature, adverse response to specific sounds or textures, excessive smelling or touching of objects, visual fascination with lights or movement).C: Symptoms must be present in the early developmental period (but may not become fully manifest until social demands exceed limited capacities, or may be masked by learned strategies in later life).D: Symptoms cause clinically significant impairment in social, occupational, or other important areas of current functioning.E: These disturbances are not better explained by intellectual disability (intellectual developmental disorder) or global developmental delay. Intellectual disability and autism spectrum disorder frequently co-occur; to make comorbid diagnoses of autism spectrum disorder and intellectual disability, social communication should be below that expected for general developmental level.Hey. Hey you.  The poor resident and or medical student that just sat through a bunch of raw criteria.  I’m sorry. A real quick aside, we have already covered some of the basics of epidemiology in a prior podcast (that’s Podcast #9 which dealt with vaccine hesitancy) Let me expand that discussion a little bit, we know that boys are about 4x as likely as girls to have it, there does seem to be a genetic component as noted in twin studies.  As far as impact it falls somewhere around 1 in 40 and 1 in 500 people.  There may be environmental factors that act as a second hit, but again see our prior podcast- studies have shown time and again no significant correlation between vaccines and autism.    There are some things which have been shown to cause a greater relative risk such as older parents, chromosomal abnormalities (such as fragile X), and certain medications taken during the prenatal period (such as valproic acid)Symptoms can present prior to 18 months, but they are most typically fully noted at 18 to 24 months when symptoms exceed the capacities of the patient. Let’s talk about something that you might need to wake up for.  Wake up. Wake up. Wake up.  The role of Primary Care is not necessarily to make the diagnosis.  Comprehensive evaluation by appropriate tools is still best left to specialists who are well trained in the field.  Most commonly developmental pediatricians, pediatric psychologist/psychiatrists, or pediatric neurologist.  However, it is very important that we recognize the signs and symptoms of autism and that we perform appropriate screening.   So, what constitutes appropriate screening? For children who appear neurotypical in whom parents are not concerned, routine screening should be implemented at ages 18 and 24 months using any of the standardized tools. The M-CHAT R/ F is validated as a first tier screening.  It is available in multiple languages through their official website.  Importantly for the primary care provider it can be completed in under 5 minutes and at least for the initial questionnaire can be completed by the parent before the visit eg either in the waiting room if given while awaiting or if the appropriate underlying electronic health record / email service is in place, the questionnaire can be given online prior to the visit.  For F component of the M-CHAT R/F is a structured set of follow up questions that should be done prior to referral.  For example, the first question: “If you point at something across the room, does (your child) look at it?”    Prompts the question, what does your child typically do?  There is a list of 7 items that are typical examples.  A child might still pass for example if he were to point at the object.  A greater concern might be when the child ignores the parent or looks at the finger instead of the object. Please note that there are other standardized questionnaires for example the Autism Spectrum Screening Questionnaire.  Most still require additional studies or are potentially better at finding other issues (such as general intellectual disability)  Resources for parentsIf the child is less than 3 years old, the Early Childhood Technical Assistance Center may be of use (especially if I am talking to people outside of my local jurisdiction)  Their website located at ectacenter.org has a contact list for coordinators that may be connect parents with services.Locally, we have the Kern Regional Center    For those 3 and older, you can contact the local public school system even for those not currently enrolled in school.For those of us in California, the Lanterman Act is very important.  The Lanterman act is the California law that gives people with developmental disabilities the right to the services and supports they need to live a more independent and normal life.  In particular, your patient may be eligible for Medi-Cal even if they might otherwise not be eligible, and they may be entitled top additional services.  Furthermore, it allows them to access for additional services through the Regional Center.  As an example, their diagnosis may entitle the family to Respite services. Now that we have identified the patient with autism, what are some of the ways that we can improve their care in our primary care.First remember that these children still need routine primary care preventive services and screening.  Anticipatory guidance may need to adapted to include some additional safety recommendations for example discussing elopement  Those with autism may have some difficulty with change, and so unfamiliar settings eg things that are not done everyday and per routine, may be more difficult.  If the patient is already in ABA therapy they may already be getting social stories or a visual board to orient the child as to expectations.  Allow additional time if possible (or manipulate your schedule to have easier / shorter appointments adjacent to this visit) to give more time to allow the patient to adapt.     Question number 3: Why is that knowledge important for you and your patients?   Question number 4: How did you get that knowledge? (learning habits)  As a general rule, I refer to multiple online sources like UpToDate to read articles and get suggestions for primary source citation. eg check the bibliography from UTD to see there sources and see if you agree with their evidence for your evidence-based medicine and primary sources.   However, for this talk I wanted to get some additional sources to discuss.  My usual go to locations for additional broad information is to first start with important medical institutions including the Center for Disease Control, World Health Organization, and AAFP. Question number 5: Where did that knowledge come from? (cite source)  I used a variety of references.  Primarily I used  UpToDate, but I also used the DSM, as well as information from the Center for Disease Control and the World Health Organization Rights Under the Lanterman Act https://www.disabilityrightsca.org/publications/rula-rights-under-the-lanterman-act-complete-manual Date of access 8/18/2020 Caldwell, Nicole.

They may instead be experiencing “lack of insight” or “lack of awareness.” The formal medical term for this condition is anosognosia, from the Greek meaning “to not know a disease.”As humans, we are consistently updating our reality and perception. Think about it this way: when you get a sunburn because you spent your weekend at the beach you expect yourself to look red when you look in the mirror. You have updated your perception of what your reality is. You now expect to appear more red. This update requires a functioning frontal lobe of the brain. When that is not working properly you can lose your ability to update what is real. Everyone else can tell you received a sunburn but you are unable to recognize you have one. In essence, this is anosognosia.This lack of insight into the disease is fairly common in those with schizophrenia and bipolar disorder. When a person is in this state they become very difficult to treat because they believe their perceptions of reality are what we should be experiencing. These people frequently will stop taking their medications because in their mind there is no reason to continue them because there is no disease.People with anosognosia often fluctuate with how aware they are of their disease. This can also cause a strain on their support system and relationships with friends and families. Since our perceptions feel accurate, we conclude that our loved ones are lying or making a mistake. If family and friends insist they're right, the person with an illness may get frustrated or angry, or begin to avoid them. When maintaining a relationship with a person with anosognosia, it is important to realize that their perception of reality is as real to them as our reality is to us.  Remember the word anosognosia.____________________________[Music]  Espanish Por Favor: Cansancioby Dr Claudia CarranzaHi this is Dr Carranza on our section Espanish Por Favor. This week’s word is cansancio. Cansancio means tiredness or fatigue. The verb “cansar” comes from the Latin word “campsare” which means to deviate or bend from a path or trajectory. Interestingly, back in the day cansancio began to be used to describe taking a break from a trip, taking a break due to exhaustion, or to rest because you’re tired. Patients can come to you with the complaint: “Doctor, tengo cansancio” or “Doctor, estoy cansado” which means: “Doctor, I am tired” or “I feel tired”. Cansancio is a very common complaint in clinic but it’s not very specific. So, the question “¿Se siente cansado?” “Are you feeling tired?” normally is answered with a yes, more so if you are a resident. Feeling tired may be physiologic, but feeling tired continually, with no relief after rest, and with no identifiable cause can lead you to start an investigation. Ask if this cansancio is new or chronic, think of differentials such as thyroid disease, anemia, sleep apnea, acute viral illness and continue with your work up. Now you know the Spanish word of the week, cansancio. ___________________________[Music]For your Sanity: Medical Jokesby Dr RAVA[SURAJ, PLEASE EDIT]I used all my sick days, so I called in dead.Statistically, 9 out of 10 injections are in vein.PMS jokes aren't funny; period.He was wheeled into the operating room, and then had a change of heart.I don't find health-related puns funny anymore since I started suffering from an irony deficiency (5). [Music to end: Jeremy Blake - Stardrive - Rock | Bright ]Now we conclude our episode number 25 “Autism with Saito”. Dr Saito explained the key features of Autism Spectrum Disorder and reminded us to screen at 18 and 24 months by using M-CHAT. Health care of patients with ASD requires a multidisciplinary team, and you can be part of that team. For some reason, we decided to expand on the word anosognosia (explained in episode 14). Cameron explained that anosognosia (UH NO SO NOGSIA) may fluctuate in intensity causing difficulty in relationships with family and friends. Dr Carranza gave us a good explanation about cansancio, which means tiredness, a good word to describe how we feel after a busy shift like today. Tomorrow the sun will rise again over the San Joaquin Valley and we’ll continue to learn and grow.This is the end of Rio Bravo qWeek. We say good bye from Bakersfield, a special place in the beautiful Central Valley of California, United States, a land where growing is happening everywhere.If you have any feedback about this podcast, contact us by email RBresidency@clinicasierravista.org, or visit our website riobravofmrp.org/qweek.

This Week in Oncology What is the role of thromboprophylaxis in patients with cancer in the outpatient setting?  Key change in ASCO recommendations: Thromboprophylaxis with apixaban, rivaroxaban, or low-molecular-weight heparin (LMWH) may be offered to select high-risk outpatients with cancer. Prophylactic anticoagulation should not be given to every patient with malignancy. Khorana score predicts the venous thromboembolism in patients with malignancy. Influenced by type of malignancy, hemoglobin, platelet count, leukocyte count, and BMI. High risk = Khorana score of 2 or higher may be offered prophylaxis. Patients with pancreatic cancer and gastric cancer are particularly coagulopathic. Does the presence of a CNS lesion(s) preclude anticoagulation for a DVT/PE? All CNS lesions have a risk of hemorrhage. A CNS lesion hemorrhage is not significantly greater when anticoagulated Among high-risk cancer patients who undergo surgery, is there a role for postoperative prophylaxis with LMWH? Data show a persistent risk of VTE up to 4 weeks following abdominal/pelvic surgery.   Show notes by Emily Bryer, DO, resident in the department of internal medicine, University of Pennsylvania, Philadelphia.   References: Venous thromboembolism prophylaxis and treatment in patients with cancer: ASCO Clinical Practice Guideline Update ascopubs.org/doi/pdf/10.1200/JCO.19.01461 Rivaroxaban for thromboprophylaxis in high-risk ambulatory patients with cancer nejm.org/doi/full/10.1056/NEJMoa1814630 Apixaban to prevent venous thromboembolism in patients with cancer nejm.org/doi/full/10.1056/NEJMoa1814468   For more MDedge Podcasts, go to mdedge.com/podcasts Email the show: podcasts@mdedge.com Interact with us on Twitter: @MDedgehemonc Ilana Yurkiewicz on Twitter: @ilanayurkiewicz

Prof Khorana talks to ecancertv at ASH 2015 about current practice patterns and patient persistence on anticoagulant treatments for cancer-associated thrombosis. In the interview he describes a study that looked at almost 3,000 patients with cancer who were newly diagnosed venous thromboembolism (VTE) and had received anticoagulant treatment in the outpatient setting. Guidelines recommend that 3–6 months of a low-molecular-weight heparin (LMWH) be given, but it is not clear if this should be continued beyond 6 months. In this real-world practice setting 25% of patients were treated with a LMWH and 18.7% received LMWH or warfarin. A further 29% had been given warfarin and 24.1% had been given the newer oral anticoagulant rivaroxaban. On average the median duration of treatment was 3.29 months for LMWH, 7.76 months for LMWH/warfarin, 8.12 months for warfarin, and 7.92 months for rivaroxaban. Persistence to the initial therapy were a respective 37%, 60%, 62%, and 61% at 6 months, dropping to 21%, 37%, 34%, and 36% at 12 months. In addition more patients initially taking LMWH were found to have switched to another anticoagulant compared to patients who had been started on warfarin or rivaroxaban.

Quality assessment looking at rivaroxaban for cancer-related thrombosis

Dr Soff talks to ecancertv at ASH 2015 about a quality assessment initiative that looked at the use of the oral anticoagulant rivaroxaban for treating cancer-related thrombosis. The current standard of care for treating patients with cancer who develop venous thromboembolism (VTE) is injected low molecular weight heparin. Rivaroxaban has been approved in the United States for the treatment for VTE since the end of 2012 but clinical trials did not specifically look at its use in cancer patients, Dr Soff explains in the interview. It was therefore decided to take a look at patients being treated with rivaroxaban for VTE according to the product’s label and make note of which of these patients also had cancer and what effects could be seen. The risk of major bleeding, which is always a concern with anticoagulant therapy, was found to be low (1.6% of patients) and recurrent thrombosis occurred in 4.4% of patients. A randomized trial is the optimal approach to establish non-inferiority or superiority of rivaroxaban to LMWH for cancer-associated thrombosis but results of the quality assessment provide guidance and reassurance for rivaroxaban use in cancer patients.

Dr Soff talks to ecancertv at ASH 2015 about the results of a study that prospectively assessed the efficacy and safety of an algorithm for reducing the dose of low molecular weight heparin (LMWH) in patients with cancer-associated thrombosis who develop chemotherapy-induced thrombocytopenia (CIT). CIT is a common problem in anticoagulated cancer patients and the current recommendation on how to amend LMWH is based on expert opinion rather published evidence, Dr Soff explains. The present study therefore aimed to address this knowledge gap and considered all 15,000 cancer patients treated with LMWH (enoxaparin) at Memorial Sloan Kettering Cancer Center over a 3-year period. There were 143 patients who developed CIT and results showed that holding anticoagulant therapy was an appropriate approach if platelet levels fell below 25,000/mcL. Halving the dose of LMWH was appropriate if the platelet count was 25,000/mcL to 50,000/mcL and continuing LMWH at full dose if the platelet count was more than 50,000/mcL.

Cancer-associated thrombosis: Switching patients to warfarin after 6-month completion of anticoagulant treatment

Dr Chai-Adisaksopha talks to ecancertv at ASH 2015 about his study that looked at the efficacy and safety of switching patients with cancer-related thrombosis to warfarin after completing 6 months of anticoagulant treatment. Extended (3–6 months) anticoagulant treatment with low-molecular-weight heparin (LMWH) is now generally recommended for patients who develop venous thromboembolism (VTE) secondary to their cancer, but not all patients tolerate this in the long term, Dr Chai-Adisaksopha says in the interview. His research suggests, however, that switching to the old standard of warfarin is just as good as continuing LMWH for preventing recurrent VTE (7.2% vs 6.0%, p = NS) with no increase in major bleeding (2.6% versus 2.7%, p = NS). Dr Chai-Adisaksopha acknowledges that this was a retrospective study and so a prospective study is needed, but the results suggest that switching to warfarin may be an option for some patients.

Thrombozyten von Patienten mit disseminierter Arteriosklerose wie bei pAVK zeigen eine erhöhte Reaktivität. In vorherigen Arbeiten wurde gezeigt, daß diese Aktivitätserhöhung postoperativ nach Gefäßeingriffen weiter ansteigt, weshalb es vermehrt zu Komplikationen auf dem kardiovaskulären Gebiet bzw. peripher zu Restenosierungen kommen kann. In dieser Dissertation soll mittels der SPAA-Methode geprüft werden, wie sich Thrombozyten von Patienten mit pAVK im Vergleich zu gesunden Kontrollen bei Inkubation mit verschiedenen Substanzen zur Thromboseprophylaxe verhalten. Aufgrund der Eigenschaften von Thrombozyten kann hinsichtlich einer Adhäsion der Thrombozyten an der Gefäßwand, in unserem Fall der Glasoberfläche und einem Haften der Thrombozyten untereinander, was als Aggregation bezeichnet wird, unterschieden werden. Das SPAA-Modell kann diese beiden Ereignisse mit hoher Sensitivität und Spezifität messen. Es zeigt sich, daß die Adhäsionsausgangswerte der pAVK-Patienten doppelt so hoch sind, wie die der Kontrollgruppe. Ebenso tritt bei diesen im Gegensatz zu den gesunden Kontrollen, bei denen keine spontane Aggregation nachweisbar ist, bereits vor den Inkubationsversuchen in 37% der Fälle eine spontane Thrombozytenaggregation auf. Das bestätigten die Ergebnisse vorangegangener Untersuchungen, daß Thrombozyten von pAVK Patienten hyperreaktiv sind. Dieses Phänomen ist nicht nur bei den Ausgangswerten mit plättchenreichem Plasma, sondern in besonderem Maße bei Zugabe von Substanzen, die in den Gerinnungsablauf eingreifen. Dabei fällt auf, wie besonders nach Zugabe von Heparinen bei Patienten eine Steigerung der Adhäsion auftritt. Auf UFH reagieren sogar Kontrollplasmen mit erhöhten Adhäsionswerten. Ein dämpfender Effekt zeigt sich bei Substanzen, die frei von Heparinfragmenten sind. Ebenso führen alle Heparine (UFH, LMWH) zu einer gesteigerten Aggregation sowohl bei Patienten als auch Kontrollen, als Ausdruck einer akuten Aktivierung. Wiederum haben von Heparinfragmenten freie Substanzen auch hier einen dämpfenden Effekt auf die Thrombozytenaggregation. Es stellt sich somit die Frage, ob für pAVK-Patienten nicht Wirkstoffe, die nicht mit Thrombozyten reagieren, von größerem Nutzen sind.
