One of the most important things clinicians can do is help patients and their families deal with impending death. Despite its importance, this part of medical care is hardly covered in medical training. Clinicians have to learn this on their own.

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.

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. Major lessons learned included accommodating for significant numbers of staff not available to work in the clinic because of school closures, change in workflow because of shortages of personal protective equipment, physicians having to accommodate very large numbers of patient queries via telephone, email, or electronic health record, and the importance of the rapid development of local ability to test for SARS-CoV-2 independent of public health agencies.
Coronovirus (the virus SARS-CoV-2) continues to spread throughout the world. In recent weeks, there has been an increasing number of cases and deaths in the US. As concern about the virus increases, there is an increasing need for accurate information about the disease and how much concern we should have. Anthony Fauci, MD, is the director of the National Institute for Allergy and Infectious Diseases (NIAID) and has been the main spokesperson for the US government about coronavirus. Dr Fauci spoke with JAMA Editor in Chief Howard Bauchner, MD, about where we are as of today with the SARS-CoV-2 epidemic.
Physicians who act out cause all sorts of problems. Fortunately, only a few clinicians have behavior problems and in the modern era, bad behaviors are not tolerated. Bad behaviors get reported these days and actions are taken against these sorts of clinicians. Clinicians who act out frequently say they are doing so to protect their patients. But are they? William Cooper, MD, MPH, and Gerald B. Hickson, MD, from Vanderbilt University Medical Center in Nashville, Tennessee, discuss a study they published in relating bad behaviors to having more complications of surgical care.

Although coronavirus disease 2019 (COVID-19) dominates the news in early 2020, it affects few people in the US. In contrast, at the same time the US is experiencing a severe influenza epidemic, which has caused an estimated 250 000 hospitalizations and 14 000 deaths. Timothy Uyeki, MD, lead for the CDC’s 2019 novel coronavirus response team and Chief Medical Officer of CDC’s influenza division, discusses influenza in the US, how it compares to coronavirus, and what both patients and clinicians should know about this year’s flu season.
Great strides have been made in treating HIV, as Anthony Fauci, MD, discusses in this podcast episode. But even substantial viral suppression leaves some virus behind, causing chronic inflammation. Many chronic diseases, including atherosclerotic coronary vascular disease, are worsened by this chronic inflammatory state. Because HIV patients are now living very long lives, they are also developing chronic diseases at a more rapid rate than their non-HIV-infected peers because of this chronic inflammation.
More than 6 million people worldwide have Parkinson disease. Even though it is classically associated with tremors, the disease has many manifestations and is very treatable for most patients. Michael S. Okun, MD, from the Department of Neurology at the University of Florida, Gainesville, discusses the pathophysiology, clinical presentation, diagnosis, and treatment of Parkinson disease.

Breast cancer is a leading cause of death in women. Some women have a cancer susceptibility gene known as BRCA, and women should be tested for BRCA under some circumstances. Carol Mangione, MD, division chief of General Internal Medicine and Health Services Research at UCLA, discusses when testing is appropriate, and Ranjit Manchanda, MD, PhD, from Barts Cancer Institute in London, UK, discusses the cost-effectiveness of BRCA screening for women who have had breast cancer.
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.

Conjunctivitis and dry eye disease are some of the most common conditions patients present with. They are usually benign entities that respond well to conservative measures and usually don’t require medications. However, if medications are necessary, clinicians can find a comprehensive assessment of these drugs recently published in the December 2, 2019, issue of The Medical Letter. An excerpt from this article summarizing information about conjunctivitis and dry eye disease was published in the February 4, 2020 issue of JAMA. Kathryn Colby, MD, PhD, chair of the Department of Ophthalmology & Visual Science at the University of Chicago, explains in this podcast how to treat conjunctivitis and dry eye disease.
