 Hot weather raises risk of stroke in older people

Fourth of December, Washington [US] (ANI): Emergency visits for stroke are increased during a heatwave, according to study presented at ESC Asia, a scientific conference organised by the European Society of Cardiology (ESC), the Asian Pacific Society of Cardiology (APSC), and the Asean Federation of Cardiology

According to study author Dr. Ryohei Fujimoto of Tsuyama Central Hospital and the Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University, Japan, "Climate change and global warming are problems that affect the entire world, and stroke is a leading cause of death."

"Our research suggests that exposure to hot weather may increase the risk of stroke in older persons. To protect people from this crippling and potentially fatal disease, preventative measures like insulated housing and air conditioning should be prioritised by the public health system.

The impact of high temperatures on the risk of stroke is not well understood. This study looked at the connection between elderly people's emergency room visits for stroke and heat exposure. 3,367 citizens of Okayama, a city in Western Japan, participated in the study. Between 2012 and 2019, participants who were 65 years of age or older were taken to emergency hospitals for strokes that began during and many months following the rainy season.

The Okayama weather station, which is operated by the Japan Meteorological Agency and the Okayama Prefectural Government, provided hourly data on outdoor temperature, relative humidity, barometric pressure, and the average atmospheric concentration of particulate matter smaller than 2.5 mm in diameter (PM2.5).

Analysis of the relationship between temperature and stroke was done during the rainy season as well as one, two, and three months later. For each participant, the researchers utilised a time-stratified case-crossover study design to compare the temperature on the day of the week a stroke occurred (for example, Monday) with the temperature on the same day of the week without strokes (for example, all other Mondays in the same month). By doing this, the possible effects of individual traits, long-term time trends, seasonality, and day of the week were avoided.

One month after the rainy season, the researchers discovered, the link between temperature and stroke was at its highest. After controlling for relative humidity, barometric pressure, and PM2.5 concentration, there was a 35% increase in the likelihood of emergency visits for stroke for every 1°C increase in temperature. Each 1°C rise in temperature was linked to a 24% higher chance of hemorrhagic stroke, a 36% higher chance of ischemic stroke, and a 56% higher chance of transient ischaemic attack when each kind of stroke was examined separately.

The researchers examined if there might be "impact modification" based on the wet season in a subsequent analysis. Effect modification refers to the possibility that the relationship between an outcome (emergency visit for stroke) and an exposure (hot air temperature) may vary based on a third variable (during and after the rainy season). The wet season served as the reference period for this investigation.

Once more, the bond was at its strongest one month after the wet season. For every 1°C increase in temperature over the reference period, the risk of stroke increased by 31%.

According to Dr. Fujimoto, the second analysis' findings indicate that the association between hot weather and stroke is amplified by the climate shortly following the rainy season. The findings may be explained by the fact that this time period is also characterised by high temperatures and longer daylight hours.

"Our study implies that older persons should try to keep cool during hot spells, for example by staying indoors during peak temperatures," the researcher said in his conclusion. In order to enable the general population escape the heat during the warmest months of the year, public health systems can offer cool areas. (ANI)

2- Can chickenpox cause heart problems?

Chicken pox (varicella) is usually a benign childhood illness, but it can occasionally cause life-threatening complications. Complications related to varicella are mainly neurologic and infectious. Cardiac complications of chicken pox include myocarditis, pericarditis, and rarely infective endocarditis

3- Can chickenpox cause myocarditis?

Myocarditis has long been associated with varicella infection. The pathological mechanism includes the direct cytopathic effect and the involvement of secondary auto-immune effects leading to myocardial cellular destruction and consecutive ventricular dysfunction
