Older adults are vulnerable to heat-related morbidity and mortality due to reduced thermoregulatory function associated with aging. The aim of this study was to examine the relationship between age and thermoregulatory behaviour during walking exercise in Control (22 °C; 40% relative humidity [RH]) and Hot (35 °C, 40% RH) conditions. Thirty-six healthy males (age 46 ± 20 (range 19-86) years; stature 177 ± 7 cm; body mass 75.

Exertional heat stress disrupts gastrointestinal permeability and, through subsequent bacterial translocation, can result in potentially fatal exertional heat stroke. Glutamine supplementation is a potential countermeasure although previously validated doses are not universally well tolerated. Ten males completed two 80-minute subclinical exertional heat stress tests (EHSTs) following either glutamine (0.

Background: Disease surveillance is a critical function of public health, provides essential information about the disease burden and the clinical and epidemiologic parameters of disease, and is an important element of effective and timely case and contact tracing. The COVID-19 pandemic demonstrates the essential role of disease surveillance in preserving public health. In theory, the standard data formats and exchange methods provided by electronic health record (EHR) meaningful use should enable rapid health care data exchange in the setting of disruptive health care events, such as a pandemic.
