Prolonged T-cell response during severe COVID-19 does not contribute to long COVID

A recent study published in eLife determines whether immune activation is associated with long coronavirus disease 2019 (COVID-19). Herein, patients with severe COVID-19 exhibited persistent activation of clusters of differentiation 8 (CD8+) and CD4+ T-cells as compared to patients with mild or moderate COVID-19. Study: Prolonged T-cell activation and long COVID symptoms independently associate with severe

Swollen legs could be a sign of silent killer cancer, warns doctor

Cervical cancer: Expert discusses 'main symptoms' of condition Cervical cancer is often dubbed the “silent killer” cancer as it can develop slowly without many noticeable symptoms. Even if someone does experience symptoms they can then be mistaken for side effects of the menstrual cycle, with vaginal bleeding and tummy pain among the most common signs.

How a genetic mutation can cause individuals with normal cholesterol to develop heart disease at a young age

A novel molecular pathway to explain how a mutation in the gene ACTA2 can cause individuals in their 30s—with normal cholesterol levels and no other risk factors—to develop coronary artery disease has been identified, according to researchers with UTHealth Houston. The study was published in the European Heart Journal. “The gene ACTA2 codes a specific

New study finds gaps in maternal immunization data sets

A study led by a University of Canterbury geospatial and population health expert has uncovered gaps in nationwide data that tracks maternal immunization rates. The study has been published in the New Zealand Medical Journal. Health Senior Lecturer Dr. Matt Hobbs is also co-director of the GeoHealth Laboratory in the University of Canterbury (UC) Geospatial

Fecal transplants show promise in improving melanoma treatment

In a world-first clinical trial published in the journal Nature Medicine, a multi-center study from Lawson Health Research Institute, the Centre hospitalier de l’Université de Montréal (CHUM) and the Jewish General Hospital (JGH) has found fecal microbiota transplants (FMT) from healthy donors are safe and show promise in improving response to immunotherapy in patients with

Researchers develop first four-arm laparoscopic surgical device

Researchers at EPFL have developed the first system that enables four-arm laparoscopic surgery by controlling two additional robotic arms via haptic foot interfaces. Roboticists at EPFL have combined multi-limb manipulation with advanced shared-control augmentation for an unprecedented advance in the field of laparoscopic surgery. The results, published in The International Journal of Robotics Research, confirm

Study uncovers gut bacteria differences in children who later develop juvenile idiopathic arthritis

For the first time, scientists have shown that gut bacteria differences are associated with later development of juvenile idiopathic arthritis, a debilitating rheumatic childhood disease, and that these differences are present years before the disease is diagnosed. The research team, which includes scientists from the University of Florida and researchers in Sweden, made this discovery

Half of Americas beaches have unsafe pollution levels: Report

A day at the beach can be fun with family and friends, but water pollution can ruin the experience. The problem is more widespread than many might think: In a new report, the Environment America Research & Policy Center, a nonprofit organization, found that half of U.S. beaches had potentially unsafe contamination levels in 2022.

Study shows vaping nicotine while pregnant may impact fetal development

Researchers at the University of Colorado Anschutz Medical Campus have found that vaping nicotine during pregnancy may be no safer for a developing fetus than smoking cigarettes. The study suggests that vaping nicotine interferes with fetal bone and lung development. The paper was published in Developmental Biology. “Pregnant women are increasingly turning to vaping with

Does the Mediterranean diet lower the incidence of type 2 diabetes among non-Mediterranean populations?

In a recent study published in the Nutrients Journal,  researchers investigated the association between adherence to the Mediterranean diet and the prevalence of type 2 diabetes in Lausanne, Switzerland — a non-Mediterranean population. Study: Association between Mediterranean Diet and Type 2 Diabetes: Multiple Cross-Sectional Analyses.

T cells require healthy mitochondria, research shows

All cells have their own power plants, called mitochondria. There are often more than 100 mitochondria per cell and each possesses their own genome, which in turn contains genes responsible for energy production. If errors creep into these genes, this can cause problems in the cell and result in diseases. Scientists from the Berlin Institute
