Infective endocarditis is a common and morbid condition involving prolonged hospital stays, significant disability, and a high mortality rate. The current crises of injection drug use and opioid use disorder have contributed to high rates of infective endocarditis in the United States. Endocarditis in patients who inject drugs involves additional management complexity for multiple reasons.

Early studies of large language models (LLMs) in clinical settings have largely treated artificial intelligence (AI) as a tool rather than an active collaborator. As LLMs now demonstrate expert-level diagnostic performance, the focus shifts from whether AI can offer valuable suggestions to how it can be effectively integrated into physicians' diagnostic workflows. We conducted a randomized controlled trial (n=70 clinicians) to evaluate the value of employing a custom GPT system designed to engage collaboratively with clinicians on diagnostic reasoning challenges.

Fourteen million people in the United States have symptomatic knee osteoarthritis (OA), a number that is expected to rise with an aging population. Patients with OA can benefit from nonoperative treatment. However, none of these treatments are disease modifying, and many patients eventually require total joint arthroplasty (TJA).

While large language models (LLMs) have shown promise in diagnostic reasoning, their impact on management reasoning, which involves balancing treatment decisions and testing strategies while managing risk, is unknown. This prospective, randomized, controlled trial assessed whether LLM assistance improves physician performance on open-ended management reasoning tasks compared to conventional resources. From November 2023 to April 2024, 92 practicing physicians were randomized to use either GPT-4 plus conventional resources or conventional resources alone to answer five expert-developed clinical vignettes in a simulated setting.

Importance: Large language models (LLMs) have shown promise in their performance on both multiple-choice and open-ended medical reasoning examinations, but it remains unknown whether the use of such tools improves physician diagnostic reasoning.

Objective: To assess the effect of an LLM on physicians' diagnostic reasoning compared with conventional resources.

Design, Setting, And Participants: A single-blind randomized clinical trial was conducted from November 29 to December 29, 2023.

Article Synopsis
  • In 2022, 1 in 8 people globally lived with obesity, prompting the use of lifestyle changes—like diet, exercise, and behavioral modifications—as the primary management strategy.
  • * With the introduction of new pharmacologic therapies, particularly glucagon-like peptide 1 receptor agonists, the American Gastroenterological Association issued guidelines recommending the addition of medications for adults with obesity who don't respond well to lifestyle changes alone.
  • * Two experts evaluate how effective both lifestyle and pharmacologic interventions are for treating obesity and discuss strategies for shared decision-making in creating a personalized treatment plan.

Management of hospitalized patients with type 2 diabetes mellitus (T2DM) presents unique challenges. Two recently released guidelines, one from the American Diabetes Association and the other from the Endocrine Society, provide useful recommendations and evidence review to inform the care of medical inpatients with T2DM. These guidelines mostly agree, although there are slight differences in their recommendations.

Article Synopsis
  • * Conducted across multiple medical institutions, the research involved 50 resident and attending physicians working on clinical vignettes, with some using GPT-4 and others using only conventional resources.
  • * Results showed a slight improvement in diagnostic scores for the GPT-4 group (76.3%) versus those using conventional resources (73.7%), but the difference was not statistically significant.

: Disrespectful behavior between physicians across departments can contribute to burnout, poor learning environments, and adverse patient outcomes. : In this focus group study, we aimed to describe the nature and context of perceived disrespectful communication between emergency and internal medicine physicians (residents and faculty) at patient handoff. We used a constructivist approach and framework method of content analysis to conduct and analyze focus group data from 24 residents and 11 faculty members from May to December 2019 at a large academic medical center.

Dementia, according to the American Psychiatric Association's , is defined by a significant decline in 1 or more cognitive domains that interferes with a person's independence in daily activities. Mild cognitive impairment (MCI) differs from dementia in that the impairment is not sufficient to interfere with independence. For the purposes of this discussion, cognitive impairment (CI) includes both dementia and MCI.

The Infectious Diseases Society of America/Society for Healthcare Epidemiology of America and the American College of Gastroenterology recently released updated guidelines on management of patients with infection. Although these 2 guidelines generally agree, there are a few important differences in their advice to clinicians. In these rounds, 2 experts, an infectious diseases specialist and a gastroenterologist, discuss antibiotic treatment options for nonsevere disease, the role of fecal microbiota transplantation for fulminant disease, and the use of bezlotoxumab to prevent recurrence in the context of Ms.

Sepsis is a potentially life-threatening systemic dysregulatory response to infection, and septic shock occurs when sepsis leads to systemic vasodilation and subsequent tissue hypoperfusion. The Surviving Sepsis Campaign published updated guidelines in 2021 on the management of sepsis and septic shock. Here, in the context of a patient with septic shock, 2 critical care specialists discuss and debate conditional guideline recommendations on using lactate to guide resuscitation, the use of balanced crystalloids versus normal saline, and the use of corticosteroids.

Colorectal cancer (CRC) is the third leading cause of cancer death for men and women in the United States, with an estimated 52 580 people expected to die in 2022. Most frequently, CRC is diagnosed among persons aged 65 to 74 years. However, among persons younger than 50 years, incidence rates have been increasing since the mid-1990s.

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.
