Podcasts about Warfarin

Stu Levitan welcomes the biographer of modern Madison, award-winning columnist Doug Moe, for a conversation about his latest book, Saving Hearts and Killing Rats: Karl  Paul Link and the Discovery of Warfarin. It's the first detailed look at one of the most important and most honored biochemists of the 20th century — the brilliant, unconventional, and seemingly bipolar University of Wisconsin scientist whose discoveries led to two synthetic compounds: the rat-killing Warfarin and the heart-saving Coumadin. And all because at the depths of the Great Depression a St. Croix farmer turned to his state government to learn why his cows were dying of internal bleeding after eating sweet clover hay that had gone bad. It's quite a story about quite a scientist, which Doug Moe tells quite well.

In this episode of the Intelligent Medicine podcast, Dr. Ronald Hoffman and Leyla Muedin engage in their weekly Q&A session, addressing listener questions on medical and nutritional topics. Dr. Hoffman discusses the lack of comprehensive nutrition education in medical schools and highlights a recent proposal by RFK Jr. to mandate nutrition courses under threat of losing federal funding. The conversation also covers the impact of various medical conditions and treatments on bone health, including the effect of Warfarin on osteoporosis. They explore the significance of sun exposure for circadian rhythms and overall health, delving into how to safely optimize sun intake. The episode concludes with practical advice on managing iron levels, particularly ferritin, and the implications it has for overall health.

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…   Kay: Hi Dr. Cabral, About a year ago, before I discovered you and your podcasts, my husband and I invested in a $4000 Tempurpedic mattress. I know that memory foam is generally synthetic and was wondering if you have recommendations to reduce any toxic effects? The instructions when we first received the mattress were to allow it to "air out" for a day, which we did. We now also sleep with an air filter in our bedroom. Any other suggestions or comments about Tempurpedic or memory foam mattresses in general? Thank you.                                                                                                                          Anonymous: Hi, this has been happening for a while & I am wondering what it means. When I wake up the inside of my nose stigns quite a lot. Sometimes it also happens during the day or it lasts throughout the day but mostly it's the worst as soon as I wake up. It's really annoying and then I usually rub my nose on the outside a lot until it subsides but it's so weird and I have no idea what it means. Please help!                                                                                                                                Lindsay: Hi Dr Cabral, I looked over your information already given on acid reflex. I have two questions. What are the long term effects of omeprazole. What is a natural alternative? Thank you, Lindsay                                                                               Anonymous: Hello Dr. C, I hope you're doing well. I wanted to reach out regarding an issue I've been experiencing. I have noticed an increase in heart rate after consuming alcohol. I never had any issues with occasional drinking prior. However, since having my first child and taking nearly two years off from alcohol, I now experience a racing heart whenever I drink. I've tried staying well-hydrated beforehand, but the issue persists. I have done a FM detox + Parasite detox in this 2 year period as well. I'm curious to hear your thoughts on what might be causing this change, especially since it wasn't a problem in the past. Could it be a histamine issue or an overflowing rain barrel still?                                       Jennifer: Thank you for all you do, Dr. Cabral! Your energy and drive inspire me! My Dad has to take Warfarin to thin his blood. What may be root causes for thickening of the blood? Where do I start?   Thank you for tuning into this weekend's Cabral HouseCalls and be sure to check back tomorrow for our Mindset & Motivation Monday show to get your week started off right! - - - Show Notes and Resources: StephenCabral.com/3341 - - - Get a FREE Copy of Dr. Cabral's Book: The Rain Barrel Effect - - - Join the Community & Get Your Questions Answered: CabralSupportGroup.com - - - Dr. Cabral's Most Popular At-Home Lab Tests: > Complete Minerals & Metals Test (Test for mineral imbalances & heavy metal toxicity) - - - > Complete Candida, Metabolic & Vitamins Test (Test for 75 biomarkers including yeast & bacterial gut overgrowth, as well as vitamin levels) - - - > Complete Stress, Mood & Metabolism Test (Discover your complete thyroid, adrenal, hormone, vitamin D & insulin levels) - - - > Complete Food Sensitivity Test (Find out your hidden food sensitivities) - - - > Complete Omega-3 & Inflammation Test (Discover your levels of inflammation related to your omega-6 to omega-3 levels) - - - Get Your Question Answered On An Upcoming HouseCall: StephenCabral.com/askcabral - - - Would You Take 30 Seconds To Rate & Review The Cabral Concept?

As we work our way through the alphabet from A to Z in my drug pronunciation series, we're on the letter “J.” I wanted to pick a popular generic drug name that starts with “J” for today's episode. It turns out that the letter “J” should be avoided in naming generic drugs, according to the United States Adopted Names Council. Therefore, there are very few generic drug names that start with the letter “J.” Instead, I chose a brand-name drug that starts with “J.”   Thank you for listening to episode 320 of The Pharmacist's Voice ® Podcast.

Discover the importance of the most neglected nutrient: magnesium! Magnesium can aid in heart attack prevention, support heart health, and improve your overall well-being. Learn more about magnesium deficiency symptoms and why magnesium is vital for cardiovascular health. DATA: https://www.ahajournals.org/doi/full/... Today I want to share some lesser-known heart health tips and how magnesium may help lower heart attack risk. Common heart problems such as plaquing, blood clots, atrial fibrillation, and hypertension are all related to magnesium deficiency. Testing for magnesium deficiency is almost impossible because only 1% is in the blood. The majority of magnesium is inside the cells. Heart medications such as calcium channel blockers, beta-blockers, Warfarin, and medications used to treat high blood pressure work using mechanisms similar to magnesium. Magnesium acts as a natural calcium channel blocker and helps regulate calcium, lower blood pressure, lower adrenaline, and relax the muscles. People deficient in magnesium often feel tired, especially after exercise. They may also experience migraine headaches. Without enough magnesium, vitamin D cannot work. Alcohol, refined sugar, starches, genetics, stress, low stomach acid, drugs, and antibiotics can interfere with the absorption of magnesium. Consuming ultra-processed foods increases your demand for magnesium and could cause you to become deficient. Many sources of magnesium, like spinach, almonds, and chocolate, are high in oxalates. Magnesium glycinate is a great choice for people looking to get more magnesium.

Let's talk about the health benefits of turmeric. One study found that curcumin was just as effective as ibuprofen at reducing pain from arthritis without side effects! It's also shown to be as effective as aspirin. Another study showed that curcumin had comparable results to Prednisone in reducing inflammation for rheumatoid arthritis, asthma, and IBS. It has also been shown to produce antidepressant effects similar to Prozac and Zoloft. Curcumin has anti-diabetic properties and effects similar to Metformin. It also has anticoagulant properties similar to aspirin and Warfarin. Research has shown that curcumin has benefits similar to statins and can help reduce LDL cholesterol and triglycerides. One study compared curcumin to 5-fluorouracil, a chemotherapy drug. Turmeric has been shown to be as effective as anti-inflammatory drugs, especially for irritable bowel disease and digestive problems. It may also help reduce blood pressure and inhibit pathogens, especially fungi. To prepare turmeric water, combine ½ teaspoon of turmeric powder, a pinch of black pepper, and half of a lemon in a glass of warm water. To prepare golden milk, combine ½ teaspoon of turmeric, ¼ teaspoon of cinnamon, and a pinch of black pepper in a cup of milk or coconut milk. Heat the mixture and remove from heat just before it comes to a boil. You can also add turmeric to a smoothie with berries and kefir. If you have a cough, try drinking a cup of hot water with a teaspoon of turmeric and a tablespoon of raw honey.

飛碟聯播網《飛碟早餐 唐湘龍時間》2024.09.17 週二醫療保健單元 潘懷宗的醫學新知時間《12種不與咖啡一起服用的藥物》 大多數歐美中年人（台灣也不少）早上起床後的例行公事，就是： 如廁盥洗→喝咖啡→早餐→吞藥（白開水）→上班。只要其中同時出現「吞藥」和「喝咖啡」這兩個項目，不論其先後順序，都是本篇文章討論的範圍。所謂「一起服用」的意思是說，在藥物治療的作用期間內，不要喝咖啡，而不是僅僅不使用咖啡吞藥丸而已。 舉例來說，葡萄柚（汁）中含有「呋喃香豆素」（Furanocoumarin），會抑制小腸及肝臟中的代謝酵素（Cytochrome P-450 3A4），由於許多藥物皆需要該酵素進行代謝，若大量食入（淺嚐1~2瓣OK，果汁不行），就會造成藥物血中濃度飆高，進而增加藥物不良反應的發生機率，而且，「呋喃香豆素」抑制酵素的作用時間，可以長達數小時，甚至2~3天，所以在服用降壓藥、降血脂藥、抗心律不整藥或免疫抑制劑等藥物的整個作用期間內，都不應該吃葡萄柚（汁）。 近日，英國《每日郵報》記者（Emily Joshu）特別邀請藥劑師（Jennifer Bourgeois）詳列了12類藥物，不應該和咖啡一起服用，提醒歐美人注意。以下為醫學院藥理教授，認為相當有通識教育意義，特別加註簡化並修改些小錯誤後，供大家參考。 1. 抗憂鬱藥 根據美國CDC估計，12歲以上的美國人中有1/10以上服用抗憂鬱藥，約3,700萬人。而抗憂鬱藥有許多種類，目前最常開出的第一線藥物SSRI（選擇性血清素回收抑制劑），像是Zoloft（樂復得）、Lexapro（立普能） 和 Fluoxetine（禧濱）等的藥物，並不會和咖啡因有交互作用。只有老一代的抗憂鬱藥（目前很少使用，但並非完全不用），如三環類藥物和單胺類氧化酶抑制劑 （MAOIs），才需要小心，它們會阻止身體正常代謝咖啡因，可能導致血壓升高，造成不良反應。一般情況下，咖啡因會以尿液形式經由腎臟排出，然而，這些藥物會中斷這個過程，使咖啡因在體內停留更久，這就會導致持續的高心跳和高血壓，這類藥物是：Fluvoxamine（氟伏沙明）、Phenelzine（苯乙肼）、Tranycypromine （反苯環丙胺） 等等。 2. 不需醫生處方的綜合感冒藥和鼻塞藥 有將近3/4的美國成年人使用非處方感冒藥和過敏藥來緩解症狀。其中許多含有興奮劑--「偽麻黃鹼」（Pseudoephedrine），它可以讓血管收縮，減少鼻黏膜的腫脹和充血，緩解鼻塞。然而，偽麻黃鹼同樣會刺激大腦中負責「戰鬥或逃跑」的警覺性神經細胞，如果與咖啡一起服用，會加劇這項效果，讓你覺得緊張和焦慮。市面上許多綜合感冒藥（含治鼻塞）或是專門治療鼻塞（Sudafed/速達菲）的藥物裡面，都含有偽麻黃鹼，大家應該詳細檢視成分，在服藥治療期間內，避免喝咖啡。若真的忍不住，服藥前4小時或服藥後2小時，才喝咖啡。 3. 糖尿病藥物 約2000萬的美國人有糖尿病，服用「庫魯化」（Metformin）藥物，甚至有200萬病患（1/10）使用胰島素，這都是想要維持血糖在標準範圍內。雖然糖尿病藥物並不會與咖啡因產生直接的交互作用，可是，當你喝咖啡時，就會增高血糖值，讓你的藥物療效降低，不利於病情，尤其是如果裡面又含有奶油和糖的話。根據美國糖尿病協會的研究，飲用任何含咖啡因的飲料都會增加血糖值。因此，量測您的血糖值，以確定您是否可以在服藥時喝咖啡。 4. 抗生素 抗生素用於治療細菌感染，根據美國CDC估計，每年約有2.3億次的感染事件，相當多。有些抗生素會抑制咖啡因的代謝，導致血中咖啡因的濃度增加。例如： 速博新（Ciprofloxacin），通常用於治療泌尿道感染、膀胱感染、感染性腹瀉和鼻竇感染，若與咖啡一起服用，就可能會導致心跳加速和感到緊張（feeling jittery）。 5. 抗凝血劑 約800萬的美國人需使用抗凝血劑來預防血栓，根據克利夫蘭診所統計，華法林（Warfarin）是歷史最久，最常開出的抗凝血劑，約占美國全部抗凝血劑處方中的1/4（也就是200萬人）。若與咖啡一起服用，可能會導致出血過多的事件，因為咖啡因會抑制華法林的分解，使藥物在體內的濃度升高，就算只是被紙割到等的輕傷，都可能會導致過度出血。不過，新一代的抗凝血劑「艾必克」（Eliuis），已經不會和咖啡因引起這些交互作用了，請認明你所吃的是哪一種抗凝血劑。若真的非喝不可，吞藥後至少要等6~8個小時。 6. 降壓藥 美國藥學院協會估計，每年有1.17億張降壓藥的處方籤，開給2,600萬的美國人，包括： 紓壓寧、康肯、達利全（β-Blockers）等藥物。這些藥物希望能降低血壓並阻止腎上腺素的作用，以便改善血液流動，並降低心跳，讓心臟不必那麼辛苦地工作。但當你喝咖啡或任何含咖啡因的飲料時，它就會加快你的心跳並升高血壓，這雖然不是直接的藥物交互作用，但更像是在對抗降壓藥的療效，相當不明智，不合邏輯，因此不應該和咖啡一起服用。若真的非喝不可，服藥前4小時或服藥後2小時，方可淺嚐一杯。 7. 甲狀腺功能低下藥物 治療甲狀腺功能低下會使用「左旋甲狀腺素」（Levothyroxine），甲狀腺功能減退症是美國處方最多的藥物之一，每年總共有2300萬張處方簽。然而，這類藥物若與任何食物或咖啡一起服用，會降低藥物吸收率達50% 之多，因此，服用左旋甲狀腺素的人應該是在飯前，空腹用白開水服藥，等30~60分鐘後，才可以進食或喝含咖啡因的飲料。 8. 阿茲海默症藥物 目前每10個65歲以上的美國成年人中就有一個被診斷出患有阿茲海默症，這是最常見的失智症。治療這種疾病症狀的藥物稱為「膽鹼酯酶抑制劑」，像是「愛憶欣」（Donepezil）和「憶思能」（Rivastigmine），可以防止乙醯膽鹼的分解，乙醯膽鹼是一種有助於記憶形成和思考的神經化學物質。若與咖啡一起服用時，咖啡因會收緊血腦屏障，使得藥物更難進入大腦，產生療效。非喝不可時，應該選在吞藥前四小時或吞藥後兩小時。 9. 骨質疏鬆症藥物 骨質疏鬆症是骨骼隨著時間的推移而變得脆弱或易斷的疾病，據美國CDC估計，有1000萬50歲以上的美國人患有此病，嚴重時，即使連咳嗽等輕微的壓力也會導致肋骨骨折，醫學界目前使用雙磷酸鹽類藥物，例如： 「安妥良」（Risedronate）和「骨維壯」（Ibandronate），來抑制蝕骨細胞，減緩骨質破壞，若與咖啡一起服用時，會導致它們無法被身體正常吸收，從而降低療效，建議吞藥後等待大約兩個小時才能喝咖啡。此類藥每月口服一次，服藥當日早上起床後，第一餐前空腹，保持上半身直立姿勢以一整杯冷開水（約 200 cc）整粒吞下（勿嚼碎或吸吮），服藥後半小時內不得躺下，不要進食。 10. 氣喘藥物 在美國，近2500萬人患有氣喘，支氣管擴張劑是用來放鬆和擴張氣道的處方藥。然而，若將「胺非林錠」（Aminophylline）和「喘克」（Theophylline）等支氣管擴張劑與咖啡一起服用，就會加劇藥物副作用，像是： 煩躁和不安，特別是剛剛開始使用這類藥物的病患，因為每個病人的反應不盡相同。您可以自行小心觀察，建議在服用這些藥物之前或之後四個小時，才喝咖啡。 11. 過動症藥物 根據CDC的數據，接近但不到1/10的17歲以下美國孩童被診斷出患有過動症，約4,100萬張處方簽被開出。過動症藥物像是： 阿德拉爾（Adderall）和利他能（Ritalin）等，可以強化腦中多巴胺和正腎上腺素等的神經傳導訊號，以改善注意力、專注力和控制衝動。然而，若與咖啡一起服用，會降低療效，產生過動，原因是咖啡因屬於中樞興奮劑，會興奮神經細胞，應該避免。 12. 抗思覺失調症狀的藥物 根據克利夫蘭診所數據，大約有400萬美國人正在服用抗思覺失調症狀的藥物，例如： 「可致律」（Clozapine）、「理思必妥」（Risperidone）和「金菩薩」（Olanzapine）等，這些藥物通常用於治療《思覺失調症》和《雙相情感障礙症》等疾病所特有的思覺失調症狀，期望透過調節多巴胺和血清素等神經傳導物質來減輕思想上和視覺上的兩項幻覺，由於咖啡因會增加藥物血中含量，所以應該遠離咖啡才是。 原文網址：https://www.chinatimes.com/opinion/20240905002864-262110?chdtv ▶ 《飛碟早餐》FB粉絲團 https://www.facebook.com/ufobreakfast/ ▶ 飛碟聯播網FB粉絲團 https://www.facebook.com/ufonetwork921/ ▶ 網路線上收聽 http://www.uforadio.com.tw ▶ 飛碟APP，讓你收聽零距離 IOS：https://reurl.cc/3jYQMV Android：https://reurl.cc/5GpNbR ▶ 飛碟Podcast SoundOn : https://bit.ly/30Ia8Ti Apple Podcasts : https://apple.co/3jFpP6x Spotify : https://spoti.fi/2CPzneD Google 播客：https://bit.ly/3gCTb3G KKBOX：https://reurl.cc/MZR0K4 -- Hosting provided by SoundOn

It is now uncommon to see warfarin therapy initiated for stroke prevention. However, quality patient care is never a “one-size-fits-all” approach.  New evidence from the FRAIL-AF trial suggests that some of our most vulnerable older adults might be better off maintained on a vitamin K antagonist rather than (automatically) switched to a direct oral anticoagulation (DOAC).   Guest Author:  Matthew Cantrell, PharmD, BCPS Music by Good Talk

In this video, we'll discuss some of ginger's health benefits and when it may not be an appropriate remedy. For thousands of years, ginger has been used as a powerful remedy for many conditions. Some of the amazing benefits of ginger include: • Antimicrobial properties • Anti-inflammatory properties • Anti-diabetic properties • Anti-cancer properties • Helping with menstrual pain • Helping with arthritis • Increasing HDL • Improving heartburn One of the most well-known uses of ginger is its ability to relieve nausea. Ginger can help with nausea associated with chemotherapy, pregnancy, menstruation, and surgery. Ginger has some contraindications, so it may not always be the best remedy for you. Don't take ginger if you're on Warfarin or other blood thinners like aspirin. Ginger helps thin the blood, so you also won't want to take it if you have a bleeding disorder. Ginger inhibits insulin, so don't take it if you're on insulin. Ginger can lower blood pressure, so avoid it if you're taking blood pressure medication. Ginger also stimulates the gallbladder, so don't consume it if you have gallstones. DATA: https://www.ncbi.nlm.nih.gov/pmc/arti... https://www.ncbi.nlm.nih.gov/books/NB...

On this episode of the Real Life Pharmacology podcast, I take a dive into the most common mechanisms of drug interactions. Below I list some of the common drug interactions seen in practice and how they work! Opposing Effects Many drugs will work on various receptors throughout the body. To use as an educational point, there is no better example to point to than the beta receptor. Beta-blockers are frequently used in clinical practice for their ability to lower blood pressure and slow the heart rate. Both of these beneficial actions are primarily achieved by blocking the effects of beta-1 receptors. Some beta-blockers have action on alternative beta receptors. Propranolol is one such beta-blocker that is classified as a non-selective beta-blockers. This means that in addition to the positive effects on beta-1 receptors, it can also have blocking effects on beta-2 receptors. The blockade of the beta-2 receptor by propranolol can also be life-changing. It can directly oppose beta-2 agonists like albuterol from having their beneficial effects of opening up the airway. Enzyme Inhibition Medication metabolism is arguably the largest and most clinically significant source for drug interactions. Medications that are primarily metabolized by enzymes in the liver can be greatly affected if we affect how those enzymes work. CYP3A4 is one of the most well studied and well-known enzymes that can impact hundreds to maybe even thousands of drugs. Apixaban is an oral anticoagulant that is broken down at least in part by CYP3A4. By using a CYP3A4 inhibitor like erythromycin, there is the potential to raise concentrations of apixaban. This could lead to a higher risk of bleeding. Enzyme Induction Carbamazepine is a drug that you must know. This drug is a potent enzyme inducer. This differs significantly from an enzyme inhibitor and will have the exact opposite clinical effect. Drugs that are inactivated by liver enzymes will be inactivated more quickly in a patient taking an enzyme inducer. Going back to our prior apixaban example above, carbamazepine can induce CYP3A4 and facilitate a more efficient and swifter breakdown of the drug. Bleeding will be less likely. The risk for treatment failure, usually in the form of a blot clot, will be more likely.  Here's more information from the past on carbamazepine. Alteration in Absorption Binding interactions can be consequential and are one of the most common types of drug interactions. Many medications have the potential to bind one another in the gut. This can lead to lower concentrations of a specific medication. Calcium and iron are two of the most common examples of medications that can bind other drugs. Alteration in Protein Binding By remembering that unbound drug is an active drug, you should appreciate the risk for protein binding alterations. A significant number of medications can bind proteins in the bloodstream. As this occurs, that drug is not freely available to create physiologic effects. When another medication is added that can also bind these proteins, this can displace other medications and increase the quantity of free drug in the bloodstream. This essentially allows for enhanced physiologic effects. Warfarin is a medication that is highly protein-bound. When another drug is added that can kick warfarin off of those protein binding sites, it can free up warfarin which will increase the likelihood of elevating the patient's INR and increase their bleed risk. Alteration in Renal Elimination Some drugs can alter the way other medications are eliminated through the kidney. Chlorthalidone, like all thiazide diuretics, has the potential to block the excretion of lithium from the kidney. This can lead to lithium toxicity. This type of interaction, while significant, is much less common than drug interactions involve the liver and CYP enzyme pathways.   Effects on Transporters One of the last types of drug interactions is the effe...

On this podcast episode, I discuss fenofibrate pharmacology, adverse effects, kinetics, drug interactions, and much more! Fenofibrate is typically only used for hypertriglyceridemia. The primary risk of hypertriglyceridemia is pancreatitis so we treat these levels because of this risk. LFTs elevation has been associated with fenofibrate use as well as myopathy. In the presence of myopathy, checking CPK may be considered. Fenofibrate is a weak CYP2C9 inhibitor. Warfarin and phenytoin are two important medications that may be affected by the use of fenofibrate.

In this week's episode we delve into the world of cardiac catheterization and speak with Assistant Professor of Pediatrics at USC, Dr. Neil Patel about a recent work he co-authored at Children's LA about continuation of anti-coagulation during catheterization. Does AC have to be stopped to safely perform a catheterization? Are there certain cases or patients in whom the risk may be especially high? What about NOACs or DOACs? When should closure devices be considered? These are amongst the questions posed to Dr. Patel this week.DOI: 10.1007/s00246-023-03097-x

Welcome to my podcast. I am Doctor Warrick Bishop, and I want to help you to live as well as possible for as long as possible. I'm a practising cardiologist, best-selling author, keynote speaker, and the creator of The Healthy Heart Network. I have over 20 years as a specialist cardiologist and a private practice of over 10,000 patients. The episode discusses common cardiac drugs and some potential drug interactions. It covers aspirin, warfarin, clopidogrel, proton pump inhibitors, beta blockers, ACE inhibitors, digoxin, nitrates, and amiodarone. Notably, grapefruit can increase serum levels of beta blockers, calcium channel blockers, and some statins, potentially leading to toxicity. Warfarin's effects can be altered by foods high in vitamin K like leafy greens. Clopidogrel's effectiveness may be reduced when taken with proton pump inhibitors like omeprazole. Combining nitrates with phosphodiesterase inhibitors like sildenafil can cause profound blood pressure drops. The host recommends being aware of possible drug interactions and maintaining regular communication with doctors.

Cancer inherently increases the risk of Deep Vein Thrombosis and Pumlmonary Embolism. This is merely a nuisance for some, while others experience significant morbidity, leading to hemodynamic instability and potential death. Historically known as "the great masquerader" with pulmonary embolisms, we explore signs, symptoms, and different approaches to treatment. Warfarin remains the original and is still an option for patients, but have better therapies emerged like direct oral anticoagulants (DOACs)? The short answer is yes, but tune in as we dive again into systematic reviews and give you a summarised version of everything you should know.Useful Links:Statpearls DVT: https://www.ncbi.nlm.nih.gov/books/NBK507708/Anticoagulation for thrombus in malignancy: https://www.uptodate.com/contents/anticoagulation-therapy-for-venous-thromboembolism-lower-extremity-venous-thrombosis-and-pulmonary-embolism-in-adult-patients-with-malignancy?search=cancer%20induced%20DVT&source=search_result&selectedTitle=4~150&usage_type=default&display_rank=4For more episodes, resources and blog posts, visit www.inquisitiveonc.comFind us on Twitter @InquisitiveOnc!If you want us to look at a specific trial or subject, email us at inquisitiveonc@gmail.comArt courtesy of Taryn SilverMusic courtesy of Music Unlimited: https://pixabay.com/users/music_unlimited-27600023/Disclaimer: This podcast is for educational purposes only.

This week, please join author Xuerong Wen, Associate Editor Sandeep Das, and Guest Host Mercedes Carnethon as they discuss the article "Comparative Effectiveness and Safety of Direct Oral Anticoagulants and Warfarin in Patients With Atrial Fibrillation and Chronic Liver Disease: A Nationwide Cohort Study." Dr. Carolyn Lam: Welcome to Circulation on the Run, your weekly podcast summary and backstage pass of the journal and its editors. We're your co-hosts. I'm Dr. Carolyn Lam, associate editor from the National Heart Center and Duke National University of Singapore. Dr. Greg Hundley: And I'm Dr. Greg Hundley, associate editor, Director of the Poly Heart Center at VCU Health in Richmond, Virginia. Dr. Carolyn Lam: Greg, I'm so excited about today's feature paper. It deals with the important condition where atrial fibrillation exists in patients with chronic liver disease and what do we do for anticoagulation in these patients. It's a comparative effectiveness and safety study of direct oral anticoagulants compared with warfarin in these patients. A huge, wonderful, important study that we're going to discuss. But before we get there, I'd like to tell you about some papers in this issue and I'd like you to tell me about some too. You got your coffee? Dr. Greg Hundley: Absolutely. Dr. Carolyn Lam: All right. I'll go first In this paper that describes a quantitative prognostic tool for the mitral valve prolapse spectrum and it's derived from the new mitral regurgitation international database quantitative or MIDA-Q registry, which enrolled more than 8,000 consecutive patients from North America, Europe, Middle East. And these were patients all diagnosed with isolated mitral valve prolapse or MVP in routine clinical practice of academic centers, all of which also did prospective degenerative mitral regurgitation quantification. The MIDA-Q score was calculated based on characteristics collected in routine practice combining the established MIDA score, which integrated guideline based markers of outcomes like age, New York Heart Association status, atrial fibrillation, LA size, pulmonary artery pressure left ventricular and systolic, I mentioned, and ejection fraction. Integrating that with scoring points based on the degenerative mitral regurgitation quantitation that is measuring effective regurgitant orifice and volume. Dr. Greg Hundley: Very interesting Carolyn. So a scoring system that combines clinical information with what we might assess with echocardiography like regurgitant volume or regurgitant orifice area. So how well did this mortality risk score perform? Dr. Carolyn Lam: So the new score was associated with an extreme range of predicted survival under medical management and that ranged from 97% to 5% at five years for the extreme score ranges. And it was strongly, independently and incrementally associated with long-term survival over all the markers of outcomes. So the authors concluded, and these by the way were authors led by Dr. Maurice Serrano from Mayo Clinic, Rochester, Minnesota. These authors concluded that the score should allow integrated risk assessment of patients with mitral valve prolapse to refine clinical decision making in routine practice and ultimately reduce degenerative mitral regurgitation under treatment. Dr. Greg Hundley: Wonderful description Carolyn. Well I'm going to switch to the world of electrophysiology, Carolyn. And so as you know, the Brugada syndrome is an inherited arrhythmia syndrome caused by loss of function variants in the cardiac sodium channel gene SCN5A and that occurs in about 20% of subjects. And these authors led by Dr. Dan Roden at Vanderbilt University School of Medicine identified a family with four individuals diagnosed with Brugada syndrome, harboring a rare missense variant in the cardiac transcription factor, TBX5, but no SCN5A variant. And upon identifying these individuals, their objective was to establish TBX5 as a causative gene in Brugada syndrome and to define the underlying mechanisms by which it would be operative. Dr. Carolyn Lam: Oh wow. So a new gene variant. So what was the relationship? Dr. Greg Hundley: Right Carolyn? So using induced pluripotent stem cell derived cardiomyocytes from members of the affected family, multiple electrophysiologic abnormalities were detected in these cardiomyocytes including decreased peak and enhanced late cardiac sodium current. In these cells these abnormalities were entirely corrected by CRISPR/Cas9 mediated editing of that TBX5 variant and transcriptional profiling and functional assays in unedited and edited pluripotent stem cell derived cardiomyocytes showed direct SCN5A down regulation caused decreased peak sodium current and that reduced PDGF receptor expression and blunted signal transduction to phosphoinositide-3-kinase. And interestingly, PDGF receptor blockade markedly prolonged normal induced pluripotent stem cell derived cardiomyocyte action potentials. And also Carolyn interestingly in this study they did a separate analysis. It reviewed plasma levels of PDGF in the Framingham Heart Study and they found that they were inversely correlated with the QT corrected interval. And so Carolyn, these results established decrease SCN5A transcription by the TBX5 variant as a cause of Brugada syndrome and also reveal a new general transcriptional mechanism of arrhythmogenesis of enhanced late sodium current caused by reduced PDGF receptor mediated phosphoinositide-3-kinase signaling. Dr. Carolyn Lam: Wow. Wow, that's significant. Thanks Greg. So this next paper is also really important and could change the practice in the field of cardiac resynchronization therapy or CRT. You see, it suggests that the practice of what we do now, which is combining right bundle branch block with intraventricular conduction delay patients into a single non-left bundle branch block category when we select patients for CRT, that this may not be the way to go. So let's go back a bit and remember that benefit from CRT varies with QRS characteristics and individual trials are actually underpowered to assess the benefit for relatively small subgroups. So the current authors led by Dr. Friedman from Duke University Hospital and colleagues, therefore performed a patient level meta-analysis of randomized trials of CRT to assess the relationship between QRS duration and morphology with outcomes. Dr. Greg Hundley: Very interesting Carolyn. So another wonderful paper from the world of electrophysiology in trying to understand optimal mechanisms to resynchronize the ventricle in patients with differing bundle branch blocks or intraventricular conduction delays. So what did they find? Dr. Carolyn Lam: They found that patients with intraventricular conduction delays and a QRS duration of 150 milliseconds or more, CRT was associated with lower rates of heart failure hospitalizations and all cause mortality. The magnitude of CRT benefit among these patients with the interventricular conduction delay of 150 milliseconds or more and those with the left bundle branch block of 150 milliseconds or more were similar. In contrast, there was no clear CRT benefit for patients with a right bundle branch block of any QRS duration, although the authors could not rule out the potential for benefit at a markedly prolonged QRS duration. So they concluded that the practice of combining right bundle branch block with intraventricular conduction delay patients into a single non-left bundle branch block category when we make patient selections for CRT is not supported by the current data. And in fact, patients with an intraventricular conduction delay of 150 milliseconds or more should be offered CRT as is done for patients with a left bundle branch block of 150 milliseconds or more. Dr. Greg Hundley: Wow, Carolyn, so really interesting point. No clear CRT benefit for patients with right bundle branch block regardless of the QRS duration. Well we've got some other articles in the issue. I'll describe a couple from the mail bag. There's a Research Letter from Professor Lassen entitled "Risk of Incident Thromboembolic and Ischemic Events Following COVID-19 Vaccination Compared with SARS-COV2 Infection." Also Bridget Kuhn has a wonderful Cardiology News piece entitled "Collaborative Care Model Helps Heart Failure Patients Meet End-of-Life Goals." Dr. Carolyn Lam: There's an exchange of letters between Doctors Donzelli and Hippisley-Cox regarding that risk of myocarditis after sequential doses of COVID-19 vaccine, there's an AHA Update by Dr. Churchwell on continuous Medicaid eligibility, the lessons from the pandemic. There's an On My Mind paper by Dr. Parkhomenko on Russia's war in Ukraine and cardiovascular healthcare. Wow, what an issue. Thanks so much, Greg. Shall we go on to the feature discussion? Dr. Greg Hundley: You bet. Dr. Mercedes Carnethon: Well welcome to this episode of Circulation on the Run podcast. I'm Mercedes Carnethon, associate editor of the journal Circulation and Professor and Vice Chair of Preventive Medicine at the Northwestern University Feinberg School of Medicine. I'm very excited to be here today with Xuerong Wen and Sandeep Das, my fellow associate editor here at Circulation to talk about a wonderful piece by Dr. Wen and colleagues from the University of Rhode Island. So welcome this morning Xuerong and thank you so much for sharing your important work with us. Dr. Xuerong Wen: Thank you Dr. Carnethon. It was great meeting you all and I'm the Associate Professor of Pharmacoepidemiology and Health Outcomes at the University of Rhode Island. I'm happy to introduce my study to everyone. Dr. Mercedes Carnethon: Well thank you so much and thank you as well Sandeep for identifying this fantastic article and bringing it forth. Dr. Sandeep Das: Thanks Mercedes. It's great to be with you. Dr. Mercedes Carnethon: Great. Well let's go ahead and get into it. There's so much here to talk about. So Dr. Wen and colleagues studied the comparative effectiveness and safety of direct oral anticoagulants or DOACs and warfarin in patients with atrial fibrillation and chronic liver disease. So this is such an important topic. Can you tell us a little bit about what your study found? Dr. Xuerong Wen: So our study is a comparative effectiveness and the safety analysis using a national health administrative data from private health plans. So we compared the risk of hospitalized ischemic stroke, systemic embolism and major bleeding between DOACs and warfarin in patients with atrial fibrillation and chronic liver disease. So we also had to had compare to these primary outcomes between apixaban and rivaroxaban in the study population. So our studies show that among patients with atrial fibrillation and chronic liver disease, DOACs as a class was associated with lower risk of hospitalization of ischemic stroke and systemic embolism and major bleeding, compared with warfarin. And when compared risk outcomes between individuals apixaban has lower risks as compared to rivaroxaban. So that's our study results. Dr. Mercedes Carnethon: Well thank you so much. This seems like such an important question. We hear a lot about DOACs and some of their risks as well as their considerable benefits. I think what leaves me the most curious is why did you choose to pursue this question and in particular in patients with both atrial fibrillation and liver disease. So why was the intersection of these two particular conditions of interest to your study team? Dr. Xuerong Wen: That's a great question. So the liver actually plays a central role in both the synthesis of coagulation factors and the metabolism of anticoagulant drugs. And the clearance of the anticoagulants in liver ranges from 20% to 100% for DOACs and warfarin. So in clinical practice anticoagulation abnormalities and elevated risk of spontaneous or unprovoked venous thrombotic complications have been reported in patients with liver disease. While these patients with cirrhosis were excluded from the clinical trials of DOACs and also population based, the real world experience is very limited. So that is why we initiated this retrospective cohort study and based on the real world data in this specific population. Dr. Mercedes Carnethon: Oh, thank you so much for explaining that. I definitely learned a lot and really enjoyed reading the piece. I think it was very well organized and well written and I know that our readership will appreciate it. It obviously stood out to you as well, Sandeep. Can you tell me a little bit about why you thought that this would be an excellent piece for circulation? Dr. Sandeep Das: Yeah, absolutely. Thanks for the question. So in the broad field of what we call observational comparative effectiveness research, so basically that's using large observational data sets to try to answer important clinical questions and it's a really challenging thing to do. I mean we're all very familiar with the idea of using randomized trials to assess important clinical questions because of the structure of that design allows you to mitigate some of the effects of confounding. Here, it has to be done analytically. So what's the important factor that really drives you towards a great observational comparative effectiveness piece? So first the clinical importance. I feel a little guilty because I'm old enough to remember when warfarin was the only option available, but really as a clinician, or every patient, I really prefer DOACs over warfarin just for ease of use and lifestyle. So there's a huge sort of importance to the question. Second, the patients with chronic liver disease were excluded from the larger RCTs and the DOAC trials. So really we don't have the answer to the question already. It's an important question. Obviously the bleeding risk is tied up with the liver, warfarin directly antagonizes vitamin K, so there's real questions about safety and so this is the perfect storm and then on top of it was a really well done and well executed study. So when this came across my desk, the very first thing I thought was not, "Is this something that we're interested?" But rather, "How do we make it better? How do we make it more useful to the reader?" This had me from hello. Dr. Mercedes Carnethon: Well thanks so much. We rarely have the opportunity when we read an article to be able to ask the authors questions. So Sandeep, I know that you had mentioned that you had some follow up questions as well. Dr. Sandeep Das: Yeah. So the real thought that I have then is would you argue based on this that we know enough that we should change our practice? And that do you feel comfortable advocating that people now prescribe DOACs to these patients? Dr. Xuerong Wen: I would say yes. Okay. Although this is not a clinical trial, but our study is actually systematically compare the effectiveness and safety between DOAC users and also the warfarin users. And if you look at our table one, we compare with so many variables between these two users and we use the propensity score adjustment and we after propensity score weighting and the two control group almost balanced. And I know right now FDA actually suggested that emulate the trial using the large real world data to do the emulated trial. So our study actually conducted is based on the large population using large data and we use the propensity score weighting to control all this potential compounding factors. Although there are still some limitations in this study. I think we mentioned that in the discussion section and we discussed all potential compounding factors that still may exist. And also there are some misclassifications and out of all this limitations and we still found the two drugs performed differently in this specific population. So we feel that comfortable to say that a DOAC drug performs better than warfarin. And also I think based on other studies that based on the clinical trial in the general population, DOAC drug is performs much better than warfarin and considering that the clearance in liver for DOAC is less than warfarin. So plus all this information together, I think DOAC may be safer than wafarin in the patients with AF and chronic liver disease. Dr. Sandeep Das: Yeah, I would say that I agree that these data, even if you're skeptical about observational CT generally, which I admit that I tend to be, these are really reassuring data that at least the DOACs are... There's absolutely nothing that suggests that they're any worse than warfarin and all of the sort of soft indications for ease of use and patient happiness really would seem to favor DOACs. So I think this is the sort of rare observational CT paper that may actually change my practice. Dr. Mercedes Carnethon: I have a follow-up question, Xuerong, related to the design and as well your strategy to address differences between the groups. So inverse probability weighting is certainly a standard in the field to be able to manage differences between groups when you have a situation where can't, where it's not a randomized trial. Do you as well, and educate me, I admit I'm an epidemiologist whose methodological skills are sometimes challenged. Do you have the opportunity using this design and with inverse probability weighting to evaluate subgroup effects? So my specific question is were you able to determine whether or not these associations were similar based on age and gender in particular? Dr. Xuerong Wen: That's a great question. We did conducted a lot of subgroup study but not by age or gender. We conducted I think this study in a lot of subgroups using the propensity score weighting, but the subgroup that I think we did a subgroup like a patient with a different chronic liver disease. So that's what we did. And we also tested different methods inverse probability score weighting. So we did trimming and we used a different percentage of trimming and to see how that affect the study results. So we have done a lot of subgroup studies. We did not check the age and the gender, but that's a very good point. Maybe later, well I'll ask my student to do that. Dr. Mercedes Carnethon: Well, you're a good mentor. So I think that is a really certainly an appropriate approach. Sandeep, did you have additional questions? Dr. Sandeep Das: No, I wish I had thought of yours before you did. I think exactly the older age, women, racial ethnic groups that are underrepresented historically in trials. I think that that's really, again, the sweet spot of this observational research. We definitely, and NH definitely working on trying to increase enrollment of all these groups in our CTs. However, while we wait for that, I think that's exactly what we should be doing. Dr. Mercedes Carnethon: Well that's great. And Xuerong, you really alluded to really, I think what is one of my final questions related to what do you think based on what you have observed in this study, what do you see as the next steps in the research field for your team, your students, or other people who are carrying out this type of work? Dr. Xuerong Wen: Well, that's a great question. We currently have a couple of more manuscripts ongoing in this field, and we will continue conducting the comparative effectiveness and analysis to compare drugs head to head as well as developing and implementing new methodologies to this field. And we hope our study provides real world evidence for clinical decision making, prescribing anticoagulants to patients with atrial fibrillation and chronic liver disease. We also expect the physicians and researchers more and more value the real world data studies, especially when clinical trials are not feasible or ethical. Dr. Mercedes Carnethon: Well, thank you so much. That was such an excellent vision that you provided us with and we're just very grateful that you submitted this fantastic work to the journal Circulation.

Efficacy and Safety of Intensive Versus Nonintensive Supplemental Insulin With a Basal-Bolus Insulin Regimen in Hospitalized Patients With Type 2 Diabetes: A Randomized Clinical Study | Diabetes Care | American Diabetes Association (diabetesjournals.org)   randomized noninferiority study from Emory University, 224 hospitalized patients with longstanding type 2 diabetes  Both groups received basal/bolus insulin; both the starting dose and subsequent changes were specified by the study protocol. Additional premeal SSI was added to scheduled premeal bolus doses.randomized to either intensive SSI (at BG >140 mg/dL) or nonintensive SSI (at BG >260 mg/dL) before meals and at bedtime.  Mean baseline glycosylated hemoglobin (HbA1c) was 9%, and 60% of patients were using insulin at home. Patients with a presenting glucose level of >400 mg/dL or diabetic ketoacidosis were excluded.  Outcome---Mean daily BG level, hypoglycemia, severe hyperglycemia, percent of BGs in the target range (70–180 mg/dL), and the amount of total, basal, or prandial insulin used did not differ between groups. However, significantly fewer patients in the nonintensive group than in the intensive group received SSI (34% vs. 91%).   COMMENTAlthough this is a single-center study, its results are persuasive and suggest that a less-intense SSI regimen can achieve similar glucose outcomes in hospitalized patients with type 2 diabetes who are receiving basal/bolus insulin. It also could decrease nursing treatment burden. As we move slowly toward more continuous glucose monitoring in hospitals, reducing use of SSI is another opportunity to achieve similar results with less staff burden and more patient comfort.  Comparative Effectiveness and Safety Between Apixaban, Dabigatran, Edoxaban, and Rivaroxaban Among Patients With Atrial Fibrillation: A Multinational Population-Based Cohort Study: Annals of Internal Medicine: Vol 175, No 11 (acpjournals.org) In a retrospective study, investigators accessed five electronic health databases from Europe and the U.S. to compare >500,000 new DOAC users with newly diagnosed atrial fibrillation. Follow up varied from 1.5 to 4.5 years.   In propensity score–adjusted analyses, patients who received apixaban had significantly less gastrointestinal (GI) bleeding did those who received any of the other three drugs (hazard ratios, 0.7–0.8). This result was consistent among older patients and those with chronic kidney disease (CKD). Risk for stroke or other systemic embolism, intracranial hemorrhage, and all-cause mortality did not differ significantly among DOACs.    COMMENTThis is the largest comparison of individual DOACs, and it demonstrates similar efficacy among all agents. Although apixaban was associated with less GI bleeding, absolute percentages of GI bleeds ranged from ≈2% to ≈3.5% for all DOACs; therefore, apixaban's statistically significant safety benefit might amount to marginal clinical benefit for any individual patient. I might turn to apixaban for patients at high risk for GI bleeding (and those with CKD), but all DOACs remain reasonable options for preventing thromboembolism in most patients with atrial fibrillation.

Actress Rue McClanahan was beloved for playing the sassy Southern Belle, “Blanche Devereaux,” on TV's The Golden Girls. But behind the smiles, Rue's life was blighted by heartbreak, disease and reported near-death experiences. Her cause of death was officially called a stroke—an event most commonly caused by a blood clot in the brain. But Rue was taking the drug Warfarin, a powerful anticoagulant prescribed to prevent blood clots. So why did the actress die of a stroke at the age of 76? World renowned Forensic Pathologist, Dr. Michael Hunter digs in to analyze every detail of of the actress' medical history to reveal if other drugs played a part in the mystery of what killed Rue McClanahan.
