Know the signs of heat stroke and exhaustion
Heat can be deadly.As summer temperatures climb — and as climate change contributes to more 100-degree days each year — heat illnesses become a more serious risk, particularly for young children, older adults, outdoor workers, athletes and people with chronic conditions.“On any day with extreme heat, emergency rooms in Los Angeles see an additional 1,500 patients,” said Dr. David Eisenman, a professor at the UCLA Fielding School of Public Health and co-leader of aresearch project to address extreme heat in Los Angeles.“We estimate that an additional 16 people die on a single day of heat in Los Angeles County,...

Coagulopathy signature precedes and predicts severity of end-organ heat stroke pathology in a mouse model.
CONCLUSIONS: Heat stroke-induced coagulopathy may be a driving mechanistic force in heat stroke pathology, especially when exacerbated by prior infection. Coagulation markers may serve as accessible biomarkers for heat stroke severity and therapeutic strategies.

Dysfunction of Iron Metabolism and Iron-Regulatory Proteins in the Rat Hippocampus After Heat Stroke
Heat stroke, the most serious type of heat illness, refers to the presence of hyperthermia (core temperature>40°C), accompanied by central nervous system dysfunction. The hippocampus is a particularly vulnerable region in the early stage of heat stroke. Increasing evidence suggests that dysregulation of brain iron metabolism is involved in many neurodegenerative diseases. However, whether heat stroke causes dysfunction of iron metabolism, as well as iron-regulatory proteins, in the hippocampus remains unknown. The present study was conducted to explore the effects on spatial learning and memory, as well as iron content, f...

Medical News Today: What to know about hypohidrosis
People with hypohidrosis sweat less than they should. This impairs the body ’s ability to cool down and can cause heat-related illnesses such as heat stroke. Hypohidrosis is a less extreme form of anhidrosis, where a person is unable to sweat. Learn about hypohidrosis here, including its causes, symptoms, and treatment.

Athletes at risk: Knowing the dangers of heat stroke
For many young athletes, fall sports practices have already started. Whether it’s football two-a-days, soccer practices on a sweltering turf field, or cross country training in the late summer sun, the threat of heat exhaustion and heat stroke is prevalent across all sports.
It’s an important time for athletes and parents to be aware of the signs of heat illnesses, especially given that children and adolescents are more susceptible to heat stroke than adults. Younger athletes produce more heat during activity, sweat less, and adjust less rapidly to changes in environmental heat.
Certain sports also carry unique risks f...

Superhero Joey: Five-year-old fights moyamoya disease
It’s been said that not all heroes wear capes — but Joey Gallagher owns several. The five-year-old has already amassed a collection of superhero gear, from a Superman Halloween costume to a t-shirt emblazoned with the Batman logo. Yet even the most diehard comic book fan would likely admit that feats like flying, leaping tall buildings and fighting bad guys don’t hold a candle to the challenges this little boy has already surmounted.
Just last June, Joey was out of town with his family when he had what his parents, Leila and Scott, feared was a seizure. Clinicians in the emergency department dismissed the event as he...

In The Marshall Islands, Traditional Agriculture And Healthy Eating Are A Climate Change Strategy
LAURA VILLAGE, Marshall Islands -- Holding in his hand a bunch of what he called mountain apples, Steve Lepton grinned like a kid with a new toy.
“Oh, it’s good,” he said. “Yesterday I didn’t find any fruit on this one. Wow, this is great. They’re getting red.”
The delicate little fruit is crunchy like an apple and sweet. It’s a popular snack in the Marshall Islands, Lepton told The WorldPost, but kids pickle it with salt and Kool-Aid, which defeats the purpose of eating fruit in the first place.
As the Global Climate and Health Alliance made clear with an announcement ...

Stress-induced cardiomyopathy accompanied by heat stroke
We describe a case with high body temperature and coma, who also presented with wide QRS tachycardia and shock. He was initially treated for heat stroke and wide QRS tachycardia. Serial electrocardiographic change and echocardiographic findings suggested this was complicated with stress-induced cardiomyopathy. This case demonstrates the importance of recognizing that serious myocardial damage can result from heat stroke. <Learning objective: Heat stroke can cause multiple organ failure and the presentation of circulatory failure in heat stroke may be the sign of myocardial dysfunction. To distinguish acute coronary ...

Epilepsy - The VA and the Missing Order
The early 1980's found me being honorably discharged from the Army. I had experienced a heat stroke that left me with gran mal and petit mal seizures associated with epilepsy, so I was somewhat surprised by the honorable instead of medical discharge. At a fairly young age, epilepsy was very much out of my experience, so it became a learning process.

Moving in extreme environments: what’s extreme and who decides?
Abstract
Humans work, rest and play in immensely varied extreme environments. The term ‘extreme’ typically refers to insufficiency or excess of one or more stressors, such as thermal energy or gravity. Individuals’ behavioural and physiological capacity to endure and enjoy such environments varies immensely. Adverse effects of acute exposure to these environments are readily identifiable (e.g. heat stroke or bone fracture), whereas adverse effects of chronic exposure (e.g. stress fractures or osteoporosis) may be as important but much less discernable. Modern societies have increasingly sought to protect pe...
