Levels of plasma SARS-CoV-2 nucleocapsid (N) antigen may be an important biomarker in patients with COVID-19 and enhance our understanding of the pathogenesis of COVID-19.

Many outpatient physicians and patients feel that current scheduling systems do not afford enough time for direct patient-physician interaction, leaving patients feeling unheard and physicians feeling demoralized. This dissatisfaction degrades patients' trust in the health care system and contributes to workforce moral injury and burnout. In the hopes of understanding the roots of this time stress and helping to guide future decisions about how to organize physicians' time, this article describes changes in the organization of U.S. outpatient physicians' time, starting from care at home in the late 19th century. It discusses the origins of the appointment system, which was invented to be highly personalized, with assistants adjusting appointment durations to accommodate clinical activities, specific patient needs, and individual physician proclivities. The article then describes how centralization of appointment scheduling became more common as U.S. medicine became increasingly consolidated into larger and larger groups and health systems. This distanced schedulers from the people and care they were organizing and necessitated standardized appointment durations, which did not accommodate individual patient and physician needs. With the rise of managerialism, schedulers became increasingly accountable to administrators rather than patients and physicians. Whereas early appointment systems depended on personal connection between schedulers and the physicians and patients they supported, today's schedulers have few such interactions. The widespread shift to centralized scheduling and standardized time slots has contributed to misalignment among time allocation, patient care, and health care workforce well-being and is likely exacerbating ongoing tensions among patients, physicians, and administrators.

The BNT162b2 (Pfizer-BioNTech) vaccine has been shown to be safe with regard to risk for severe cardiovascular events (such as myocardial infarction [MI], pulmonary embolism [PE], and stroke) in persons aged 75 years or older. Less is known about the safety of other COVID-19 vaccines or outcomes in younger populations.

Periconception folic acid supplementation has been suggested to protect against congenital heart disease (CHD), but the association between maternal red blood cell (RBC) folate, the gold-standard biomarker of folate exposure, and subsequent offspring CHD risk is lacking.

Left atrial appendage occlusion (LAAO) is a potential alternative to oral anticoagulants in selected patients with atrial fibrillation (AF). Compared with anticoagulants, LAAO decreases major bleeding risk, but there is uncertainty regarding the risk for ischemic stroke compared with anticoagulation.

The Association for the Advancement of Blood and Biotherapies reported a thorough analysis of existing data and guidelines for the use of COVID-19 convalescent plasma (CCP) for treatment and prophylaxis of COVID-19. The editorialists discuss the recommendations, how they compare with recommendations from other entities, and the lessons the experience with CCP provides for the use of passive immunotherapy for future emerging infectious diseases.

Coronavirus disease 2019 convalescent plasma (CCP) has emerged as a potential treatment of COVID-19. However, meta-analysis data and recommendations are limited. The Association for the Advancement of Blood and Biotherapies (AABB) developed clinical practice guidelines for the appropriate use of CCP.

Eating disorders are common behavioral disorders associated with substantial psychological and physical morbidity and mortality. Persons with eating disorders frequently present to primary care providers, who may also be responsible for their general medical management. This article reviews the diagnosis, medical assessment, and treatment of the most common eating disorders.

Hepatitis C virus (HCV) reinfection after successful treatment may reduce the benefits of cure among people who inject drugs.

Pulmonary embolism can be acutely life-threatening and is associated with long-term consequences such as recurrent venous thromboembolism and chronic thromboembolic pulmonary hypertension. In 2020, the American Society of Hematology published updated guidelines on the management of patients with venous thromboembolism. Here, a hematologist and a cardiology and vascular medicine specialist discuss these guidelines in the context of the care of a patient with pulmonary embolism. They discuss advanced therapies such as catheter-directed thrombolysis in the short-term management of patients with intermediate-risk disease, recurrence risk stratification at presentation, and ideal antithrombotic regimens for patients whose pulmonary embolism was associated with a transient minor risk factor.

Ensovibep (MP0420) is a designed ankyrin repeat protein, a novel class of engineered proteins, under investigation as a treatment of SARS-CoV-2 infection.

The Women's Preventive Services Initiative (WPSI), a national coalition of women's health professional organizations and patient advocacy representatives, developed a recommendation for counseling midlife women aged 40 to 60 years with normal or overweight body mass index (BMI; 18.5 to 29.9 kg/m2) to maintain weight or limit weight gain to prevent obesity with the long-term goals of optimizing health, function, and well-being. This recommendation is intended to guide clinical practice and coverage of clinical preventive health services for the Health Resources and Services Administration and other stakeholders. Clinicians providing preventive health care to women in primary care settings are the target audience for this recommendation.
