During the past decade, growing recidivism has threatened the enormous beneficial impacts of vaccinations in the United States. The barriers are multifactorial and include increasing vaccine hesitancy. The continuing dedicated efforts of all healthcare professionals, along with advancements in vaccine technology and the resilience of public health systems, offers promise for the future. ⋯ Healthcare providers and public health officials should remain cognizant that increasing vaccination rates are essential but not sufficient. Surveillance containment entails rapid detection and reporting of cases with prompt immunization of household members and close contacts of confirmed cases, combined with judicious use of isolation, prompt antiviral or antibiotic medications, social distancing, respiratory etiquette, home or large-scale quarantines, and masking. The continuing and expanded efforts of US healthcare providers are vital to these successes.

This review addresses important issues that face practitioners today concerning the treatment of heart failure with preserved ejection fraction (HFpEF). It points out how the accepted efficacy of HFpEF medication treatment has changed. Medications are now recommended for use in HFpEF that have diuretic properties and are significant because of a reduction in the frequency of the development of heart failure (not mortality). ⋯ Chlorthalidone, possibly with a generic mineralocorticoid antagonist, could be an acceptable low-cost alternate therapy as secondary treatment for HFpEF. Of course, chlorthalidone does not have the other theoretic benefits of the sodium-glucose cotransporter 2 (SGLT2) inhibitors or finerenone. It would be helpful if this was discussed in the upcoming HFpEF guidelines, especially for use in patients who cannot afford or tolerate the new HFpEF medications.

From the time of Galen, examination of the pupillary light reflex has been a standard of care across the continuum of health care. The growing body of evidence overwhelmingly supports the use of quantitative pupillometry over subjective examination with flashlight or penlight. At current time, pupillometers have become standard of care in many hospitals across 6 continents. This review paper provides an overview and rationale for pupillometer use and highlights literature supporting pupillometer-derived measures of the pupillary light reflex in both neurological and non-neurological patients across the health care continuum.

Dysfunction of the coronary microvasculature has become increasingly recognized as an important mechanism of myocardial ischemia in patients without obstructive coronary artery disease. The causes and management of coronary microvascular dysfunction remain poorly understood and are still largely based on extrapolation of epicardial coronary artery disease data. Quantification of myocardial blood flow and flow reserve have improved diagnosis, though important questions remain. In this review, we explain current understanding of the spectrum of pathophysiology of coronary microvascular dysfunction, summarize current diagnostic techniques to assess for coronary microvascular dysfunction, and appraise the limited data on management options specifically for patients with coronary microvascular dysfunction.

Medical microbiology laboratories play an essential role in patient care-appertaining to infectious diseases diagnostics and treatment, infection prevention, and antimicrobial stewardship. Collaboration between clinicians and the microbiology laboratory can promote and enhance the safety, quality, and efficiency of patient care. We review practical, evidence-informed core concepts to explicate how effective partnership between clinicians and the microbiology laboratory improves patient outcomes.
