The emerging role of alarmin-targeting biologics in the treatment of patients with COPD.

Topic Importance: Chronic obstructive pulmonary disease (COPD) is a complex, heterogeneous lung disease characterized by persistent airflow limitation secondary to airways and parenchymal abnormalities, and respiratory symptoms, including dyspnoea, fatigue, chronic cough, and sputum production. Cigarette smoke exposure is a major contributor to COPD although inhalation of toxic particles and other environmental and host factors can contribute to its genesis. Over time, the clinical course is frequently punctuated by exacerbations that further accelerate lung function decline and increase exacerbation risk.

Per- and polyfluoroalkyl substances, apolipoproteins and the risk of coronary heart disease in US men and women.

Background: Existing evidence for associations of per- and polyfluoroalkyl substances (PFASs) with blood lipids, lipoproteins and apolipoproteins (apo), and coronary heart disease (CHD) risk is limited and inconsistent. This study aims to explore associations between plasma PFASs, blood lipoprotein subspecies defined by apolipoproteins, and CHD risk.

Methods: A case-control study of CHD was conducted in the Health Professionals Follow-Up Study (HPFS) and Nurses' Health Study (NHS).

Comparison of 3D facial photographs and clinical documentation in patients with craniofacial morphea.

Diagnosis of craniofacial morphea (CM) relies upon clinical examination of progressive craniofacial changes. We assess the utility of 3D stereophotogrammetry in documenting asymmetry of the face compared to clinical notetaking. This retrospective study of 3D images and clinical documentation included 32 patients (mean age 15.

Longitudinal analysis of lifestyle risk factors, nutrition status, and drivers of food choice among urban migrants in Ulaanbaatar, Mongolia and Almaty, Kazakhstan: a formative study.

Objective: To quantify and compare concurrent within-person trends in lifestyle risks, nutrition status, and drivers of food choice among urban migrants in Central Asia.

Design: We collected panel data on household structure, drivers of food choice, nutrition knowledge, and diverse measures of nutrition status and lifestyle risk from urban migrants at 0, 3, 6, and 9 months using harmonized methodology in two cities. Trends were analyzed using mixed-effects models and qualitatively compared within and between cities.

Open-source electrophilic fragment screening platform to identify chemical starting points for UCHL1 covalent inhibitors.

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.

Global adherence to a healthy and sustainable diet and potential reduction in premature death.

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.

Examining the Role of Medical School Faculty in Developing Students' Cultural Humility Skills: Insights From a Single-Center Multimethod Study.

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.

Test for comparing the associations of multiple exposures with a common outcome.

Introduction: With advancement of medicine, alternative exposures or interventions are emerging with respect to a common outcome, and there are needs to formally test the difference in the associations of multiple exposures.

Methods: The paper proposes a duplication method-based multivariate Wald test in the Cox proportional hazard regression model to test the difference in the associations of multiple exposures with a same outcome. This method applies to continuous or categorical exposures.

Extreme altitude-induced central sleep apneas lasting more than 100 seconds in a healthy 23-year-old man.

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.

Ultra-Processed Foods and the Impact on Cardiometabolic Health: The Role of Diet Quality.

The consumption of ultra-processed foods (UPFs) has surged globally, raising significant public health concerns due to their associations with a range of adverse health outcomes. This review aims to elucidate potential health impacts of UPF intake and underscore the importance of considering diet quality when interpreting study findings. UPF group, as classified by the Nova system based on the extent of industrial processing, contains numerous individual food items with a wide spectrum of nutrient profiles, as well as differential quality as reflected by their potential health effects.

Synovial tissue myeloid dendritic cell subsets exhibit distinct tissue-niche localization and function in health and rheumatoid arthritis.

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.
