BACKGROUND: Vaccination against respiratory syncytial virus (RSV) during pregnancy may protect infants from RSV disease. Efficacy and safety data on a candidate RSV prefusion F protein-based maternal vaccine (RSVPreF3-Mat) are needed. METHODS: We conducted a phase 3 trial involving pregnant women 18 to 49 years of age to assess the efficacy and safety of RSVPreF3-Mat. The women were randomly assigned in a 2:1 ratio to receive RSVPreF3-Mat or placebo between 24 weeks 0 days and 34 weeks 0 days of gestation...

Enfortumab vedotin (EV) is a novel treatment option for patients with advanced/metastatic urothelial carcinoma who have progressed after chemotherapy and immunotherapy. Two patients at two different New England tertiary cancer care centers were treated with EV while concurrently receiving hemodialysis (HD), where a complete response to EV in both patients was noted. The use of EV in patients requiring HD is extrapolated from the available pharmacokinetic and pharmacodynamic literature on monoclonal antibodies in patients requiring HD...

We study the long-term effects on hospital activity of a three-year national integration programme. We use administrative data spanning from 24 months before to 22 months after the programme, to estimate the effect of programme discontinuation using difference-in-differences method. Our results show that after programme discontinuation, emergency admissions were slower to increase in Vanguard compared to non-Vanguard sites. These effects were heterogeneous across sites, with greater reductions in care home Vanguard sites and concentrated among the older population...

BACKGROUND: Plexins are large transmembrane receptors for the semaphorin family of signalling proteins. Semaphorin-plexin signalling controls cellular interactions that are critical during development as well as in adult life stages. Nine plexin genes have been identified in humans, but despite the apparent importance of plexins in development, only biallelic PLXND1 and PLXNA1 variants have so far been associated with Mendelian genetic disease. METHODS: Eight individuals from six families presented with a recessively inherited variable clinical condition, with core features of amelogenesis imperfecta (AI) and sensorineural hearing loss (SNHL), with variable intellectual disability...

Recent studies indicate that Generative Pre-trained Transformer 4 with Vision (GPT-4V) outperforms human physicians in medical challenge tasks. However, these evaluations primarily focused on the accuracy of multi-choice questions alone. Our study extends the current scope by conducting a comprehensive analysis of GPT-4V's rationales of image comprehension, recall of medical knowledge, and step-by-step multimodal reasoning when solving New England Journal of Medicine (NEJM) Image Challenges - an imaging quiz designed to test the knowledge and diagnostic capabilities of medical professionals...

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. Coronavirus disease 19 research was excluded. The New England Journal of Medicine (NEJM), The Lancet, Journal of the American Medical Association (JAMA), The British Medical Journal (BMJ), Annals of Internal Medicine, JAMA Internal Medicine, and Mayo Clinic Proceedings were reviewed...

OBJECTIVE: To describe the clinical, endoscopic, histologic, and treatment outcomes of Helicobacter heilmannii (H. heilmannii) associated gastritis in children in the New England region of the United States. METHODS: Retrospective study of children (1-18 years) with H. heilmannii identified on gastric mucosal biopsies from two pediatric centers over a 21-year period, January 2000-December 2021. Cases were identified by querying pathology databases at each institution...

BACKGROUND: Suboptimal communication between clinicians remains a frequent driver of preventable adverse health care-related events, increased costs, and patient and physician dissatisfaction. METHODS: Cross-sectional surveys on preoperative interspecialty communication, tailored by stakeholder type, were administered to (1) primary care providers in northern New England, (2) anesthesia providers working in the perioperative clinic of a tertiary rural academic medical center, (3) surgeons from the same center, and (4) older surgical patients who underwent preoperative assessment at the same center...

STUDY OBJECTIVE: To study racial and ethnicity disparities in randomized clinical trials (RCT) in Minimally Invasive Gynecologic Surgery (MIGS). DESIGN: Cross sectional study. SETTING: Online review of all published MIGS RCTs in high-impact journals from 2012 to 2023. PATIENTS: Journals included all Q1 Obstetrics & Gynecology journals, as well as The New England Journal of Medicine, The Lancet, The British Medical Journal, and The Journal of the American Medical Association...

A multinational outbreak of nosocomial fusarium meningitis occurred among immunocompetent patients who had undergone surgery with epidural anesthesia in Mexico. The pathogen involved had a high predilection for the brain stem and vertebrobasilar arterial system and was associated with high mortality from vessel injury. Effective treatment options remain limited; in vitro susceptibility testing of the organism suggested that it is resistant to all currently approved antifungal medications in the United States...

With the advent of Large Language Models (LLMs) like ChatGPT, the integration of Generative Artificial Intelligence (GAI) into clinical medicine is becoming increasingly feasible. This study aimed to evaluate the ability of the freely available ChatGPT-3.5 to generate complex differential diagnoses, comparing its output to case records of the Massachusetts General Hospital published in the New England Journal of Medicine (NEJM). Forty case records were presented to ChatGPT-3.5, prompting it to provide a differential diagnosis and then narrow it down to the most likely diagnosis...

Artificial intelligence has demonstrated a promising potential for diagnosing complex medical cases, with Generative Pre-Trained Transformer 4 (GPT-4) being the most recent advancement in this field. This study evaluated the diagnostic performance of the GPT-4 in comparison with that of its predecessor, GPT-3.5, using 81 complex medical case records from the New England Journal of Medicine. The cases were categorized as cognitive impairment, infectious disease, rheumatology, or drug reactions. The GPT-4 achieved a primary diagnostic accuracy of 38...

As an alternative to the Frequentist p-value, the Bayes factor (or ratio of marginal likelihoods) has been regarded as one of the primary tools for Bayesian hypothesis testing. In recent years, several researchers have begun to re-analyze results from prominent medical journals, as well as from trials for FDA-approved drugs, to show that Bayes factors often give divergent conclusions from those of p-values. In this paper, we investigate the claim that Bayes factors are straightforward to interpret as directly quantifying the relative strength of evidence...

BACKGROUND: Testosterone treatment in men with hypogonadism improves bone density and quality, but trials with a sufficiently large sample and a sufficiently long duration to determine the effect of testosterone on the incidence of fractures are needed. METHODS: In a subtrial of a double-blind, randomized, placebo-controlled trial that assessed the cardiovascular safety of testosterone treatment in middle-aged and older men with hypogonadism, we examined the risk of clinical fracture in a time-to-event analysis...

BACKGROUND: Maternal morbidity and mortality is rising in the United States. Previous studies focus on patient attributes, and most of the national data are based on research performed at urban tertiary care centers. Although it is well understood that nurses affect patient outcomes, there is scant evidence to understand the nurse work system, and no studies have specifically studied rural nurses. The authors sought to understand the systems-level factors affecting rural obstetric nurses when their patients experience clinical deterioration...
