Iron regulatory protein 2 (IRP2), a post-transcriptional regulator of cellular iron metabolism has been associated with susceptibility to chronic obstructive pulmonary disease (COPD). Resistive breathing (RB) is the hallmark of the pathophysiology of obstructive airway diseases, especially during exacerbations, where increased mechanical stress is imposed on the lung. We have previously shown that RB, through tracheal banding, mimicking severe airway obstruction, induces pulmonary inflammation and injury in previously healthy mice.

Genome-wide association studies performed in patients with coronavirus disease 2019 (COVID-19) have uncovered various loci significantly associated with susceptibility to SARS-CoV-2 infection and COVID-19 disease severity. However, the underlying -regulatory genetic factors that contribute to heterogeneity in the response to SARS-CoV-2 infection and their impact on clinical phenotypes remain enigmatic. Here, we used single-cell RNA-sequencing to quantify genetic contributions to -regulatory variation in 361,119 peripheral blood mononuclear cells across 63 COVID-19 patients during acute infection, 39 samples collected in the convalescent phase, and 106 healthy controls.

Precision medicine is transforming healthcare by offering tailored treatments that enhance patient outcomes and reduce costs. As our understanding of complex diseases improves, clinical trials increasingly aim to detect subgroups of patients with enhanced treatment effects. Biomarker-driven adaptive enrichment designs, which initially enroll a broad population and later restrict to treatment-sensitive patients, are gaining popularity.

Buddhist Jhāna meditation and the Christian practice of speaking in tongues appear wildly distinct. These spiritual techniques differ in their ethical, theological, and historical frames and seem, from the outside, to produce markedly different states of consciousness-one a state of utter calm and the other of high emotional arousal. Yet, our phenomenological interviews with experienced practitioners in the USA found significant points of convergence.

Advances in the Regulation of Periostin for Osteoarthritic Cartilage Repair Applications.

Biomolecules

November 2024

Department of Surgical and Interventional Sciences, Faculty of Medicine and Health Sciences, McGill University, Montreal, QC H3G 2M1, Canada.

Article Synopsis
  • - The study investigates the role of periostin (POSTN) in osteoarthritis (OA), finding it is increased in patients and linked to inflammation and cartilage breakdown, suggesting it could be a target for therapy.
  • - Link N (LN), a peptide from link protein, is shown to have anabolic properties and can reduce inflammation and degradation in cartilage, leading the researchers to explore its effects on POSTN expression.
  • - Experimental results reveal that LN can decrease POSTN expression and disrupt its signaling in chondrocytes, indicating it has potential as a therapeutic agent in treating OA by targeting POSTN.

Data-Driven Cutoff Selection for the Patient Health Questionnaire-9 Depression Screening Tool.

JAMA Netw Open

November 2024

Department of Epidemiology, Biostatistics and Occupational Health, McGill University, Montréal, Québec, Canada.

Article Synopsis
  • The study investigates how using small datasets to select an optimal cutoff score for the Patient Health Questionnaire-9 (PHQ-9) can lead to inaccurate results.
  • Researchers evaluated whether data-driven methods for cutoff selection resulted in scores that were significantly different from the true population optimal score and if these methods produced biased accuracy estimates.
  • Findings showed that many small studies frequently failed to identify the correct optimal cutoff score, particularly in smaller samples, leading to an overestimation of test sensitivity.

J Scleroderma Relat Disord

May 2024

Lady Davis Institute for Medical Research, Jewish General Hospital, Montreal, QC, Canada.

Article Synopsis
  • Limited research on oral health in systemic sclerosis prompts a scoping review to identify studies related to quality of life across five key domains: symptoms, functional impacts, psychosocial factors, patient-related variables, and self-care practices.
  • From 1460 studies reviewed, only 91 were included, with most being conducted in Europe or North America and featuring small participant numbers, indicating a significant gap in comprehensive research.
  • The majority of studies focus on oral manifestations and symptoms, with fewer addressing other crucial areas; further systematic reviews and larger studies are essential to improve understanding and care for systemic sclerosis patients.
