Inflammatory profiles, gut microbiome, and kidney function are impacted after high-fidelity firefighter training

Madelyn C. Houser et al.

Summary: Firefighters are at risk for systemic inflammation and kidney disease due to their occupational exposures. This pilot study conducted in a controlled field setting found that firefighters in a training course experienced symptoms of heat-related illnesses, dehydration, and changes in inflammation, kidney function, and gut microbiota composition.

Acute L-glutamine supplementation does not improve gastrointestinal permeability, injury or microbial translocation in response to exhaustive high intensity exertional-heat stress

Henry B. Ogden et al.

Summary: The study found that acute low-dose glutamine (GLN) supplementation may worsen intestinal permeability before high-intensity exertional-heat stress, but does not influence small intestinal epithelial injury or microbial translocation.

Changes in Cytokines Concentration Following Long-Distance Running: A Systematic Review and Meta-Analysis

Micael Deivison de Jesus Alves et al.

Summary: Long-distance running leads to increased inflammation, particularly in IL-6 levels. The impact of running distance on inflammatory response is not significant. Besides IL-6, other cytokines also show changes in concentration. Prolonged aerobic exercise provides protection against chronic systemic inflammation. Variability in running volume modulates compounds involved in homeostasis and cell signaling.

Individually experienced heat stress among elderly residents of an urban slum and rural village in India

Charles A. Weitz et al.

Summary: The study finds that the elderly, especially those living in slums, are more likely to experience dangerous heat index levels in India. Furthermore, active elderly individuals are more affected by heat than inactive/sedentary elderly. The research highlights the growing public health challenge posed by extreme summer heat in India, particularly for older adults.

Kazuki Shimizu et al.

Summary: The 2020 Tokyo summer Olympic and Paralympic Games were postponed to 2021 due to the COVID-19 pandemic. Research indicates an increase in patients with both COVID-19 and heat-related illnesses during the pandemic, highlighting the importance of respecting science. Urgent measures are needed to address the double burden of COVID-19 and heat-related illnesses on healthcare services in Tokyo.

Short-term heat acclimation preserves knee extensor torque but does not improve 20 km self-paced cycling performance in the heat

John O. Osborne et al.

Summary: Short-term heat acclimation training may increase knee extensor strength without changes in central fatigue or intestinal damage. However, this type of training is insufficient to improve 20 km self-paced cycling performance in the heat compared to workload-matched training in a temperate environment.

Amlan Kumar Patra et al.

Summary: Heat stress can affect the gut microbiota composition, mucosal structure, immune responses, and production performance in farm animals, ultimately leading to reduced feed intake and productivity. The exact mechanisms of how these biological responses are influenced by heat stress still need to be further elucidated.
