Background: We aimed to characterize factors associated with the under-studied complication of cognitive decline in aging people with long-duration type 1 diabetes (T1D).

Methods: Joslin "Medalists" (n = 222; T1D ≥ 50 years) underwent cognitive testing. Medalists (n = 52) and age-matched non-diabetic controls (n = 20) underwent neuro- and retinal imaging.

Purpose: Lumbar spinal stenosis (LSS) is a frequently occurring condition defined by narrowing of the spinal or nerve root canal due to degenerative changes. Physicians use MRI scans to determine the severity of stenosis, occasionally complementing it with X-ray or CT scans during the diagnostic work-up. However, manual grading of stenosis is time-consuming and induces inter-reader variability as a standardized grading system is lacking.

The deposition of amyloid-β (Aβ) aggregates and metal ions within senile plaques is a hallmark of Alzheimer's disease (AD). Among the modifications observed in Aβ peptides, -terminal truncation at Phe4, yielding Aβ, is highly prevalent in AD-affected brains and significantly alters Aβ's metal-binding and aggregation profiles. Despite the abundance of Zn(II) in senile plaques, its impact on the aggregation and toxicity of Aβ remains unexplored.

Background: The immune response to infections may become dysregulated and promote myocardial damage contributing to heart failure (HF). We examined the relationship between infection-related hospitalization (IRH) and HF, HF with preserved ejection fraction, and HF with reduced ejection fraction.

Methods And Results: We studied 14 468 adults aged 45 to 64 years in the ARIC (Atherosclerosis Risk in Communities) Study who were HF free at visit 1 (1987-1989).

Background: Objective indices of functional capacity in patients with diabetic cardiomyopathy and stage B heart failure (HF) have not been comprehensively defined. We sought to characterize the cardiopulmonary exercise characteristics of individuals with diabetic cardiomyopathy at high risk for overt HF.

Methods: The relationships from cardiopulmonary exercise testing with clinical and laboratory characteristics of participants with diabetic cardiomyopathy were evaluated using baseline data from the ARISE-HF trial (Aldose Reductase Inhibition for Stabilization of Exercise Capacity in Heart Failure).

Background: This study protocol introduces the Integrative Health Equity and Anti-Racism Tool (IHEART), an innovative instrument designed to infuse equity, diversity, and inclusion (EDI) into Integrative Health (IH) education. Recognizing the gaps in current IH training that fail to address social and systemic inequities adequately, the IHEART is intended to respond to the growing need for inclusivity in IH practices and educational materials. The tool is mainly focused on addressing issues such as accessibility of complementary and integrative health (CIH) therapies, cultural misappropriation, anti-racism, gender diversity, disability justice, trauma-informed care, weight inclusivity, and planetary health, which are currently inconsistently covered in IH training.

Purpose: A recent update of consensus guidelines for the management of Cushing's disease (CD) included indications for medical therapy. However, there is limited evidence regarding their implementation in clinical practice. This study aimed to evaluate current medical therapy approaches by expert pituitary centers through an audit conducted to validate the criteria of Pituitary Tumors Centers of Excellence (PTCOEs) and provide an initial standard of medical care for CD.

Objective: To compare physical activity (PA) over midlife between (1) former collegiate athletes and non-athletes and (2) among athletes in different sports.

Methods: The Harvard Alumni Health Study (HAHS) is a prospective cohort study of male undergraduates who completed serial questionnaires regarding PA and health status between 1962 and 1993. PA was categorised by intensity (<3 METs, light; 3 to <6 METs, moderate; ≥6 METs, vigorous), and energy expenditure (kilocalories (kcal)/week) was estimated at each intensity and in total.

Extracellular volume expansion drives vertebrate axis elongation.

Curr Biol

January 2025

Department of Genetics, Harvard Medical School, Boston, MA 02115, USA; Department of Pathology, Brigham and Women's Hospital, Boston, MA 02115, USA. Electronic address:

The vertebrate bauplan is primarily established via the formation of embryonic tissues in a head-to-tail progression. The mechanics of this elongation, which requires the presomitic mesoderm (PSM), remain poorly understood. Here, we find that avian PSM explants can elongate autonomously when physically confined in vitro, producing a pushing force promoting posterior elongation of the embryo.

Background: For decades, poor treatment options and low-quality evidence plagued care for patients with rifampin-resistant tuberculosis. The advent of new drugs to treat tuberculosis and enhanced funding now permit randomized, controlled trials of shortened-duration, all-oral treatments for rifampin-resistant tuberculosis.

Methods: We conducted a phase 3, multinational, open-label, randomized, controlled noninferiority trial to compare standard therapy for treatment of fluoroquinolone-susceptible, rifampin-resistant tuberculosis with five 9-month oral regimens that included various combinations of bedaquiline (B), delamanid (D), linezolid (L), levofloxacin (Lfx) or moxifloxacin (M), clofazimine (C), and pyrazinamide (Z).

The Epstein-Barr virus (EBV) infects nearly 90% of adults globally and is linked to over 200,000 annual cancer cases. Immunocompromised individuals from conditions such as primary immune disorders, HIV, or posttransplant immunosuppressive therapies are particularly vulnerable because of EBV's transformative capability. EBV remodels B cell metabolism to support energy, biosynthetic precursors, and redox equivalents necessary for transformation.

Reviews of the effectiveness of medicinal cannabis for chronic pain vary in their conclusions. IASP has identified that a key missing evidence in this debate is data from observational cohort studies, analyzed with comparative effectiveness methods. In a medically supervised context to the use of marijuana for chronic pain, we identified 440 patients certified for medical marijuana by pain specialists in a single healthcare system.

Center for Evidence-Based Imaging, Department of Radiology, Brigham and Women's Hospital, Harvard Medical School, 1620 Tremont Street, Boston, MA 02120 Phone: 617-525-9702.

Automated extraction of actionable details of recommendations for additional imaging (RAIs) from radiology reports could facilitate tracking and timely completion of clinically necessary RAIs and thereby potentially reduce diagnostic delays. To assess the performance of large-language models (LLMs) in extracting actionable details of RAIs from radiology reports. This retrospective single-center study evaluated reports of diagnostic radiology examinations performed across modalities and care settings within five subspecialties (abdominal imaging, musculoskeletal imaging, neuroradiology, nuclear medicine, thoracic imaging) in August 2023.

Background: The inverse relationship between increased surgical team familiarity and reduced operative time is established, but its effect on patient outcomes remains uncertain.

Materials And Methods: A prospective cohort study including operations by attending surgeons between 1 November 2020 and 31 December 2021 across fourteen surgical departments from four French university hospitals. Surgical team familiarity was measured as the cumulative number of previous operations performed by the same dyad of attending and assisting surgeons.
