Cough, exercise, and sex headaches are underrecognized distinct but related syndromes, triggered by rapid rises in intra-abdominal pressure. All may occur as a manifestation of a possible underlying, symptomatic etiology, and additional diagnostics should typically be pursued to rule out serious causes. Cough headaches may be more common in certain ...

Skeletal muscle can synthesize testosterone and 5α-dihydrotestosterone (DHT) from dehydroepiandrosterone (DHEA) via steroidogenic enzymes in vitro, but hormone levels and steroidogenic enzyme expression decline with aging. Resistance exercise has been shown to increase in plasma sex steroid hormone levels. However, it remains unclear whether resistance training can restore impaired steroidogenic ...

Decreased physical performance is a well-known consequence of rapid ascent to high altitude. Hypoxic pulmonary vasoconstriction (HPV) potentially limits cardiac output and systemic blood flow, thus preventing successful adaptation to rapid ascent. We hypothesized that pharmacological enhancement of the heart rate with theophylline, combined with reversal of HPV via endothelin ...
