Acquired heat acclimation in rats subjected to physical exercise under environmental heat stress alleviates brain injury caused by exertional heat stroke
Conclusions: This HA model can ameliorate brain injury of EHS by reducing cerebral edema and cell apoptosis, offering experimental evidence for EHS prophylaxis.PMID:37150340 | DOI:10.1016/j.brainres.2023.148393

Multiparametric cardiac magnetic resonance reveals persistent myocardial inflammation in patients with exertional heat illness
ConclusionsWith multiparametric CMR, EHI patients demonstrated increased global ECV, T2, and persistent myocardial inflammation at 3-month follow-up after EHI episode. Therefore, multiparametric CMR might be an effective method in evaluating myocardial inflammation in patients with EHI.Clinical relevance statementThis study showed persistent myocardial inflammation after an exertional heat illness (EHI) episode demonstrated by multiparametric CMR, which is a potential promising method to evaluate the severity of myocardial inflammation and guide return to work, play, or duty in EHI patients.Key Points•EHI patients showed...

Association between cooling temperature and outcomes of patients with heat stroke
This study explored the relationship between body temperature and adverse outcomes in patients with heat stroke to identify the optimal target body temperature within the first 24 h. This retrospective, multicentre study enrolled 143 patients admitted to the emergency department and diagnosed with heat stroke. The primary outcome was the in-hospital mortality rate, while secondary outcomes included the presence and number of damaged organs and neurological sequelae at disch arge. A body temperature curve was built using a generalized additive mixed model, and the association between body temperatures and outcomes was est...

Forecasting feels-like temperatures as a strategy to reduce heat illnesses during sport events
Many athletes, amateur and professional alike, compete in and train for outdoor running events every year, and even more participate in outdoor sports in general. Many major sport events such as the Summer Olympic and Paralympic Games and World Championships take place in summer and mostly in the Northern Hemisphere. Therefore, athletes are often at risk of sustaining heat illnesses during heat extremes, which are exacerbated by climate change.1 Heat illnesses describe a group of pathologies ranging from relatively minor to very severe symptoms such as potentially fatal exertional heat stroke.2 3 The risk for heat illnesse...

GSE160899 Does heat stroke induces heat intolerance?: What genes tell us
Contributors : Michal Horowitz ; Dani Kopeliovich ; Yoav Smith ; Sharona Elgavish ; Hagai Shermann ; Dani S MoranSeries Type : Expression profiling by arrayOrganism : Homo sapiensRNA samples of each group, extracted from PBMCs (Peripheral blood mononuclear cell) , were hybridized on two dye array. Within groups and between groups analyses to identify canonical pathways and enriched biological annotations were conducted.

A Small-for-Gestational-Age Infant with MIRAGE Syndrome Who Developed Heat Stroke and Rhabdomyolysis due to Severe Temperature Instability
This report describes heat stroke and rhabdomyolysis caused by anhidrosis as a symptom of MIRAGE syndrome in a small-for-gestational-age (SGA) female neonate born at 32 weeks of gestation (birth weight, 911 g [-3.8 SD]). She developed severe temperature instability with anhidrosis, growth failure, mild developmental delay, hypothyroidism, and intractable enteropathy. On day 156, her temperature reached 42.0°C; her fever persisted for 2 h with prolonged irritability. Her serum creatine kinase level increased to a peak value of 12,716 (normal range, 43-321) IU/L. The clinical feature was diagnosed as rhabdomyolysis caused b...

Immersive Cooling in the Prehospital Setting for Heat Stroke: A Case Report
Prehosp Emerg Care. 2023 Apr 11:1-5. doi: 10.1080/10903127.2023.2201515. Online ahead of print.ABSTRACTNon-exertional heat stroke is defined as exposure to high outdoor temperatures, core body temperature >40 °C, and alteration of mentation. Early identification and treatment are imperative to reduce morbidity and mortality in these patients. Cold water immersion therapy is the most efficient and efficacious modality in treating heat stroke, yet it is rarely initiated in the prehospital setting. We outline a case of an 82-year-old man found unconscious outside during a regional heat wave with a temperature >107F. He...

ACSM Expert Consensus Statement on Exertional Heat Illness: Recognition, Management, and Return to Activity
Curr Sports Med Rep. 2023 Apr 1;22(4):134-149. doi: 10.1249/JSR.0000000000001058.ABSTRACTExertional heat stroke is a true medical emergency with potential for organ injury and death. This consensus statement emphasizes that optimal exertional heat illness management is promoted by a synchronized chain of survival that promotes rapid recognition and management, as well as communication between care teams. Health care providers should be confident in the definitions, etiologies, and nuances of exertional heat exhaustion, exertional heat injury, and exertional heat stroke. Identifying the athlete with suspected exertional hea...
