Update in Outpatient General Internal Medicine: Practice-Changing Evidence Published in 2023.
The expansive scope of internal medicine can make it challenging for clinicians to stay informed about new literature that changes practice. Guideline updates and synthesis of relevant evidence can facilitate incorporation of advancements into clinical practice. The titles and abstracts from the seven general medicine journals with highest impact factors and relevance to outpatient internal medicine were reviewed by six internal medicine physicians. ⋯ Article qualities and importance were debated until consensus was reached. Clusters of articles pertinent to the same topic were considered together. In total, seven practice-changing articles were included.

Management of Clostridioides difficile infection: Diagnosis, Treatment, and Future Perspectives.
Clostridioides difficile infection is the most common healthcare-associated infection in the United States, with potential life-threatening complications and a significant impact on the costs of care. Antibiotic stewardship as well as discontinuation of chronic acid suppressive therapy are key for its prevention and treatment. Effective infection management requires appropriate interpretation of diagnostic tests, as well as the use of vancomycin and fidaxomicin as first-line treatment. Novel treatments such as Bezlotoxumab, fecal microbiota transplant, and live biotherapeutic products are proven effective in recurrent C. difficile infection and address dysbiosis.

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 is 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.

Hypertension is a primary contributor to cardiovascular disease, and the leading risk factor for loss of quality adjusted life years. Up to 50% of the cases of hypertension in the United States remain uncontrolled. Additionally, 8%-18% of the hypertensive population have resistant hypertension; uncontrolled pressure despite 3 different antihypertensive agents. ⋯ Initial randomized (non-sham) trials and registry analyses showed impressive benefit, but the first sham-controlled randomized controlled trial using monopolar radiofrequency ablation showed limited benefit. With refinement of techniques to include multipolar radiofrequency, ultrasound denervation, and direct ethanol injection, randomized controlled trials demonstrated significant blood pressure improvement, leading to US Food and Drug Administration approval of radiofrequency- and ultrasound-based denervation technologies. In this review article, we summarize the major randomized sham-controlled trials and societal guidelines regarding the efficacy and safety of renal artery denervation for the treatment of uncontrolled hypertension.

From the time of Galen, examining of the pupillary light reflex has been a standard of care across the continuum of healthcare. The growing body of evidence overwhelmingly supports the use of quantitative pupillometry over subject examination with flashlight or penlight. At current time, pupillometers have become standard-of-care in many hospitals across six 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 healthcare continuum.
