Management of COVID-19-related respiratory failure differs from what is necessary for ARDS. Rather than having alveolar edema, COVID-19 patients have pulmonary vascular dysregulation. Gas exchange is severely compromised with little reduction in lung compliance. Ventilatory support for COVID-19 patients requires higher than normal tidal volumes with minimal PEEP and allowance for higher than usual serum CO2 levels. How the unique pathophysiology of respiratory failure should be treated is discussed by John J. Marini, MD, professor of medicine at the University of Minnesota.

Kransdorf, MD, MPH, from UCLA Health in California, discusses the diagnosis and management of NASH from a primary care clinician's perspective.
COVID-19 has rapidly spread throughout the world and has a reasonably high mortality rate as compared with the flu. There has been an international shutdown of all normal daily activities because of this pandemic. Carlos d, MD, Rio from Emory University is an internationally recognized expert on infectious disease and commented on where things are now with COVID-19.
Nathan Pritikin was a college dropout who became an entrepreneur. While doing research for the government during World War II, he observed that populations that had extremely limited food availability because of the war had substantially reduced mortality from cardiovascular disease—something unexpected at a time when cardiovascular disease was thought to be due to stress. After the war when food became more available CVD death rates went back up, resulting in Pritikin concluding that CVD was related to diet. Pritikin devised his own very low-fat diet that bears his name and the diet is still in use 65 years later. Related: The Pritikin Diet The Lost Lectures from Nathan Pritikin (drmcdougall.com)
Seattle was one of the first US cities to have a COVID-19 outbreak, with a cluster of nursing home-related deaths. However, many people who tested positive for the novel coronavirus never became ill, and in some the clinical illness was indistinguishable from influenza. John Lynch, MD, MPH, an infectious disease physician and medical director for infection prevention and control at the Harborview Medical Center, summarizes his hospital’s experience managing the patients and outbreak.
Seattle has been a focal point for the US in the coronavirus pandemic. Doug Paauw, MD, professor of medicine at the University of Washington, in Seattle, describes the UW primary care clinic experience as this pandemic evolved.

Controversy exists regarding how to best manage chronic stable angina. Intuitively, it seems that because it is usually caused by coronary artery lesions, addressing those lesions either via percutaneous coronary angiography or coronary artery bypass operations would be the best way to manage this problem. Several studies have suggested that this is not the case and that results of these interventions are no better than optimal medical management. Recently, a very large trial examining this clinical question has provided results suggesting that any approach works about the same. We interviewed Donald Lloyd-Jones, MD, chair of the department of preventive medicine at Northwestern University, during the recent American Heart Association meeting about this issue.

Very few people who think they are allergic to penicillin actually are. Yet, even if someone reports a remote and vague history of penicillin allergy, these very useful medications will not be given. This forces many patients to use antibiotics that may be too broad spectrum, not very effective, or expensive. Three major societies have come together to agree on an approach for assessing if penicillin allergy is really present when a patient reports an allergy to these medications. Erica S. Shenoy, MD, PhD, from Massachusetts General Hospital in Boston, author of a JAMA review on the topic, discusses this very important problem.

The statistical concept of Bayes comes up in clinical medicine all the time. It simply means that what you know about something factors into how you analyze it. This contrasts with the commonly used statistical approach called frequentist analysis of hypothesis testing, in which it is assumed that every situation is unique and not influenced by the past. Bayesian analysis accounts for how prior information gets factored into decision making and is important to understand when applying clinical research findings to the delivery of medical care. In this interview Anna E. McGlothlin, PhD, senior statistical scientist at Berry Consultants in Austin, Texas, explains these concepts for clinicians. Read the article: Bayesian Hierarchical Models

In 2015, JAMA published results of a randomized clinical trial showing that antibiotic treatment for acute appendicitis was feasible. Doubters of the efficacy of antibiotics for treating appendicitis were concerned about what the long-term recurrence rate would be for those patients treated without surgery. The 5-year results of the study are now presented, showing that only about 40% of patients treated with antibiotics ultimately go on to have an appendectomy.

There are new findings about another form of Borrelia: Borrelia miyamotoi. This form of Borrelia causes a relapsing fever but is spread in the same way that Lyme disease is. To help understand these new findings we spoke with Eugene Shapiro, MD, from the Department of Pediatrics and Department of Epidemiology of Microbial Diseases at Yale.
Syphilis is on the rise despite prior successful efforts to control it. Why is it coming back and what needs to be done about it? Dr Charles Hicks from UC San Diego explains. This podcast coincides with updated syphilis screening recommendations from the USPSTF that were published in the September 4, 2018 issue of JAMA.
Up to 7% of the entire US population has alcohol use disorder. It’s important for every clinician to understand how to approach patients to question them about their use of alcohol and to establish a diagnosis when alcohol use disorder is present. Dr Henry Kranzler, from the University of Pennsylvania, is an authority on managing alcohol use disorder and discusses its diagnosis and treatment in this JAMA clinical reviews podcast.

Bleeding is one of the most common preventable causes of death. It is common, yet most people don't know what to do about it when they see it. The Stop the Bleed campaign is an effort to educate the public should they encounter people who are bleeding. Simple maneuvers can have a great beneficial effect. In this JAMA Clinical Reviews podcast, we hear from people with substantial experience in managing bleeding in the field and what they recommend for managing this otherwise deadly problem.

As the AIDS crisis unfolded, each discovery seemed to lead to a new mystery. Who was at risk? Why was this disease of immune activation so hard for the body to fight? Most important, what could be done to stop it? In the conclusion of this JAMA Clinical Reviews series, we'll continue the story of the small team of CDC clinicians on the frontlines of the AIDS epidemic as they worked to stem the flow of this devastating disease.
When AIDS first appeared in the gay community in 1981, it was terrifying for patients and clinicians alike. Nobody knew exactly what was going on. But using basic epidemiologic methods, a small team of public servants at the CDC raced against the clock to unravel the mystery, doing their best to minimize the damage of this rapidly spreading disease.
Misplaced fears about IUDs have caused them to be avoided by many women, despite the fact that they are very safe and among the most effective means for contraception. In this JAMA Clinical Reviews podcast, we review long-acting reversible contraception (LARC) and how contraceptive practices were affected by the Dalkon Shield tragedy.
Health care spending in the United States is out of control. The most significant aspect of medical care driving this spending is pharmaceuticals; within pharmaceuticals the greatest increases have been in spending for diabetes medications. The cost of insulin analogs has increased 5- to 6-fold in the last 10 years for no particular reason. More than 90% of US patients who use insulin use these analogs, despite the fact that they have few if any clinical benefits relative to regular or NPH insulin, which cost 1/10 as much. Aside from the cost of insulin, diabetes is probably treated far more aggressively than necessary since clinical trials demonstrating the benefits of aggressive glucose control for type 2 diabetes demonstrated vanishingly small benefits of this form of treatment. In this podcast we discuss the perplexing case of spending too much money on diabetes treatment.
The American College of Physicians just changed its guidance for how aggressively to treat type 2 diabetes, relaxing the HbA1c goal to something below 8 rather than 6.5 or 7 as other organizations recommend. This has stirred up substantial controversy. The rationale behind this decision is presented in this podcast. Related article
For many years guidelines have recommended against obtaining ECGs for low-risk patients undergoing routine health examinations. Yet about a fifth of all patients having these exams get an ECG. Why? Are clinicians just stubborn or uninformed or are the guidelines missing something clinicians are concerned about? Read the article: The Screening ECG and Cardiac Risks
