Target-based screening of covalent fragment libraries with mass spectrometry has emerged as a powerful strategy to identify chemical starting points for small molecule inhibitors or find new binding pockets on proteins of interest. These libraries span diverse chemical space with a modest number of compounds. Screening covalent fragments against purified protein targets reduces the demands on the mass spectrometer with respect to absolute throughput, detection limit, and dynamic range.

The Planetary Health Diet (PHD), also known as the EAT-Lancet reference diet, was developed to optimize global dietary quality while keeping the environmental impacts of food production within sustainable planetary boundaries. We calculated current national and global adherence to the PHD using the Planetary Health Dietary Index (PHDI). In addition, we used data on diet and mortality from three large US cohorts (n = 206,404 men and women, 54,536 deaths) to estimate the total and cause-specific mortality among adults 20 y of age and older that could be prevented by shifting from current diets to the reference PHD.

Background: While the Liaison Committee on Medical Education emphasizes the teaching of cultural competence in medical education, the concept of cultural humility, focusing on self-reflection and lifelong learning, has been proposed as a more effective approach. Although there have been numerous discussions on both topics, understanding how faculty in clinical settings help students develop cultural humility skills remains limited.

Objective: Our multimethod study utilized a survey and semi-structured interviews to identify strategies that faculty at one institution use to help students develop cultural humility skills.

Central sleep apneas (CSA) can occur de novo at high-altitude in individuals without sleep-disordered breathing at low altitude. These apneas are usually brief, lasting only 5-15 s. This report presents the first documented case of a man experiencing extreme altitude-induced CSA lasting more than 100 s in the absence of any sleep breathing disorder in normoxia.

Research into Inflammatory Arthritis Centre Versus Arthritis (RACE), Glasgow, UK; School of Infection & Immunity, University of Glasgow, Glasgow, UK. Electronic address:

Current rheumatoid arthritis (RA) treatments do not restore immune tolerance. Investigating dendritic cell (DC) populations in human synovial tissue (ST) may reveal pathways to reinstate tolerance in RA. Using single-cell and spatial transcriptomics of ST biopsies, as well as co-culture systems, we identified condition- and niche-specific DC clusters with distinct functions.

Powassan virus (POWV) is an emerging tick-borne virus that causes severe meningoencephalitis in the United States, Canada, and Russia. Serology is generally the preferred diagnostic modality, but PCR on cerebrospinal fluid, blood, or urine has an important role, particularly in immunocompromised patients who are unable to mount a serologic response. Although the perceived poor sensitivity of PCR in the general population may be due to the biology of infection and health-seeking behavior (with short viremic periods that end before hospital presentation), limitations in assay design may also contribute.

Article Synopsis
  • The study investigates how bone marrow-derived pro-inflammatory macrophages and embryo-derived reparative macrophages impact progressive heart failure with reduced ejection fraction (HFrEF) and explores the potential of mesenchymal precursor cells (MPCs) to improve patient outcomes.
  • In the DREAM-HF trial, significant risk factors for cardiovascular death (CVD) were identified in patients with HFrEF, particularly inflammation and ischaemic aetiology, which increased the risk by 61% and 38%, respectively.
  • The introduction of MPCs led to notable reductions in major adverse cardiovascular events (MACE) by 88% and 52% over a 30-month follow-up in patients with ischaemic HFrEF and inflammation.

Plasma prolactin and postmenopausal breast cancer risk: a pooled analysis of four prospective cohort studies.

Breast Cancer Res

November 2024

Department of Biostatistics and Epidemiology, School of Public Health and Health Sciences, University of Massachusetts, Amherst, MA, 01003, USA.

Background: Prolactin, a hormone produced by the pituitary gland, regulates breast development and may contribute to breast cancer etiology. However, most epidemiologic studies of prolactin and breast cancer have been restricted to single, often small, study samples with limited exploration of effect modification.

Methods: The Biomarkers in Breast Cancer Risk Prediction consortium includes 8,279 postmenopausal women sampled from four prospective cohort studies, of whom 3,441 were diagnosed with invasive breast cancer after enrollment.

Article Synopsis
  • Vehicular emissions significantly contribute to urban air pollution, primarily through the release of ultrafine particles (UFPs) that are harmful to respiratory and cardiovascular health.* -
  • A study conducted in a New Jersey hospital parking garage measured PM levels, finding that UFP mass concentrations were higher in summer (3.59 µg/m) than winter (2.51 µg/m), with UFPs containing harmful substances like elemental carbon and polycyclic aromatic hydrocarbons (PAHs).* -
  • Modeling showed that a substantial portion (23.61%) of these UFPs enters the lungs, leading to significant exposure (10.67 µg in winter and 15.25 µg in summer)

Background: Current asthma guidelines, including those of the European Respiratory Society (ERS) and American Thoracic Society (ATS), suboptimally predict asthma remission, disease severity, and health-care utilisation. We aimed to establish a novel approach to assess asthma severity based on asthma health-care burden data.

Methods: We analysed prospectively collected data from the Severe Asthma Research Program III (SARP III; USA) and the European Unbiased Biomarkers for the Prediction of Respiratory Disease Outcomes (U-BIOPRED; 11 European countries) to calculate a composite burden score based on asthma exacerbations and health-care utilisation, which was modified to include the use of short-acting beta agonists (SABAs) to reflect asthma symptom burden.
