Environmental high temperature (heat stroke) causes articular cartilage damage in vivo and in vitro.

Heatstroke (HS) is gradually becoming a major challenge in the field of global public health with the trend of global warming. In recent years, extreme high-temperature weather events have occurred frequently in the world, which directly led to a significant increase in heatstroke. However, up to now, the potential pathological effects of HS on articular cartilage have not been revealed.

Curcumin's Protective Role in Heatstroke-Induced Acute Liver Injury: Targeting Pyroptosis and Enhancing SIRT1 Expression.

Heatstroke (HS) is a severe systemic condition that significantly impacts organ function, with the liver being particularly vulnerable. Sirtuin 1 (SIRT1), a crucial deacetylase, is implicated in various diseases' pathophysiology. Curcumin, a natural polyphenol, has been shown to modulate SIRT1 activity, offering therapeutic benefits.

Characteristics of lower respiratory tract pathogens in critically ill patients with heatstroke: a retrospective multi-center study.

This retrospective multicenter study was conducted across 83 intensive care units (ICUs) in 16 cities in Sichuan, China. Critically ill patients diagnosed with heatstroke and lung infections were included in the study. Specimens from the lower respiratory tract were collected for microbiological testing, and the characteristics of the pathogens were described.

Fatal Exertional Heat Stroke Trends in Secondary School Sports From 1982 Through 2022.

Background: Exertional heat stroke (EHS) is a leading cause of secondary school sport-related death; however, a longitudinal analysis on observed trends is lacking. Our purpose was to describe EHS deaths in United States secondary school athletes since the 1982/1983 academic year.

Hypothesis: EHS deaths will be primarily represented by football athletes and have a stable or increasing trend across a decade-by-decade analysis.

Early life stress modulates neonatal somatosensation and the transcriptional profile of immature sensory neurons.

Early life stress (ELS) is associated with an increased risk of experiencing chronic pain during adulthood, but surprisingly little is known about the short-term influence of ELS on nociceptive processing in the immature nervous system and the concomitant effects on somatosensation in the neonate. Here, we investigate how ELS modulates pain in neonatal mice and the transcriptional and electrophysiological signatures of immature dorsal root ganglia (DRG). Shortly after the administration of a neonatal limiting bedding (NLB) paradigm from postnatal days (P)2 to P9, both male and female pups exhibited robust hypersensitivity in response to tactile, pressure, and noxious cold stimuli compared with a control group housed under standard conditions, with no change in their sensitivity to noxious heat.

Death after sauna-case report of a heat stroke associated subarachnoid hemorrhage.

Heat exposure could cause organ injuries leading to multi-organ failure. This case report describes a cardiopulmonary healthy 61-year-old woman who was admitted to our university hospital in an unconscious state after spending more than 30 min in an 80°C sauna. Initial radiological imaging revealed no pathological findings.

Role of COX6C and NDUFB3 in septic shock and stroke.

Background: Septic shock is a clinical syndrome characterized by acute circulatory disturbance. Stroke is an acute cerebrovascular disease caused by brain tissue damage. However, the relationship of COX6C and NDUFB3 to them is unclear.

Effect of Ischemic Preconditioning on Endurance Running Performance in the Heat.

Ischemic preconditioning (IPC) is a strategy that may enhances endurance performance in thermoneutral environments. Exercising in the heat increases thermoregulatory and cardiovascular strain, decreasing endurance performance. The current study aimed to determine whether IPC administration improves endurance performance in the heat.

Computational modeling of basal ganglia hemorrhage morphology improves functional outcome prognostication after minimally invasive surgical evacuation.

Introduction: Anatomic factors that predict outcomes following basal ganglia intracranial hemorrhage (bgICH) evacuation are poorly understood. Given the compact neuroanatomic organization of the basal ganglia, we hypothesized that bgICH spatial representation could predict postoperative functional outcomes.

Methods: Patients undergoing minimally invasive surgical bgICH evacuation between 2013 and 2024 at one center were retrospectively reviewed.

Glutamine Supplementation: A Possible Strategy to Help Mitigate Health Risks of Heat-Related Illness.

A rise in body temperature caused by physical work, including exercise, in a hot climate can lead to heat-related illnesses such as exertional heat exhaustion and stroke. Individuals who work physically demanding occupations in hot environments are at heightened risk of heat injury. The mechanisms that contribute to heat illness resulting from physical work in the heat are complex and include dehydration, tissue ischemia and damage, oxidative stress, and inflammatory events.

Coexisting metabolic dysfunction-associated steatotic liver disease exacerbates in-hospital outcomes in patients with heat stroke.

Purpose: This study aimed to investigate the impact of coexisting metabolic dysfunction-associated steatotic liver disease (MASLD) on in-hospital mortality and organ injury markers in patients with heat stroke (HS).

Approach: HS patients were retrospectively identified between July 1, 2022 and September 30, 2023 at West China Hospital, Sichuan University. Baseline characteristics, such as demographics, initial vital signs, and organ functional indicators were collected.

(Hero20) Gene Polymorphism: Contribution to Ischemic Stroke Risk and Interactions with Other Heat-Resistant Obscure Chaperones.

: Recently identified Hero proteins, which possess chaperone-like functions, are promising candidates for research into atherosclerosis-related diseases, including ischemic stroke (IS). : 2204 Russian subjects (917 IS patients and 1287 controls) were genotyped for fifteen common SNPs in Hero20 gene using probe-based PCR and the MassArray-4 system. : Six SNPs were significantly associated with an increased risk of IS in the overall group (OG) and significantly modified by smoking (SMK) and low fruit/vegetable intake (LFVI): rs10766342 (effect allele (EA) A; P( = 0.

Current Situation of Heat Stress Studies on Kendo Players: A Scoping Review.

Global warming and the rise in the average temperature in recent years have increased the risk of heat stroke and also deteriorated performance among athletes. Kendo, a traditional Japanese martial art and also a competitive sport, is reported to have high incidents of heat stroke and related mortality. However, there is no heat management guideline for this specific sport to date and research on its heat management practices and risk factors for heat stroke are limited.

Exertional Heatstroke Encephalopathy With Chronic Neurological Deficit.

Heat exhaustion progresses to heat stroke and then on to heatstroke encephalopathy, a serious illness. Extreme hyperthermia (over 40.5 °C), central nervous system failure, multiorgan dysfunction, and hypovolemic shock are the hallmarks of the clinical presentation of heatstroke.

The Clinical Profile of Heatstroke Patients Admitted to the Intensive Care Unit: A Case Series From a Tertiary Care Center in New Delhi, India.

Heat-related illnesses include a spectrum of disorders ranging from heat syncope, muscle cramps, and heat exhaustion to heat emergencies such as heatstroke. Severe heatwaves can lead to extremely high environmental temperatures and a spurt of cases of heat-related illnesses and heatstroke. The incidence of such heat-related medical emergencies was much higher in 2024 compared to previous years throughout North and Central India.

Catalytic enhancement in the performance of the microscopic two-stroke heat engine.

We consider a model of heat engine operating in the microscopic regime: the two-stroke engine. It produces work and exchanges heat in two discrete strokes that are separated in time. The working body of the engine consists of two d-level systems initialized in thermal states at two distinct temperatures.

The Impact of Global Warming on the Rise in Heat-Related Illnesses in Emergency Medical Services.

Purpose: Global warming is one of the critical problems affecting health, society, and the economy. High temperatures are linked to an increase in heat-related illnesses, which have significantly impacted the public health system, particularly emergency medical services (EMS). Analyzing the pattern of heat-related illness cases in EMS can improve resource utilization and preparedness within the public health system.
