Long-Term Use of Postmenopausal Estrogen Treatment May Impair Kidney Function
Long-term estrogen treatment after menopause may increase the risk of new kidney damage and negatively affect women with abnormal kidney function. New research published in the American Journal of Physiology—Renal Physiology finds that markers for kidney damage worsened in a rat model of menopause as the length of estrogen treatment increased.
Smoke + Hot Temperatures = Increased SIDS Risk
Researchers are a step closer to understanding why cigarette smoke exposure during pregnancy may increase the risk of sudden infant death syndrome (SIDS). SIDS is the unexplained, sudden death of a child younger than one year of age. A new study published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology finds that prenatal cigarette smoke exposure in rats affected breathing responses and immune function of their offspring. Breathing and immune function are further negatively affected by high room temperatures.
Study Explores How Immune System Functions During Sleep
Research published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology gives new insight into sleep’s importance to overall health: it may give the immune system a chance to regroup at a time when the relative risk of infection is low.

Rat Study Shows that Renal Denervation Helps to Bring Drug-Resistant Hypertension under Control
Most clinical studies have shown that renal denervation—a procedure that disrupts the nerves in the kidneys and prevents them from relaying signals—can treat drug-resistant hypertension, although a number have shown the procedure to be ineffective. A new study in the American Journal of Physiology—Regulatory, Integrative and Comparative Physiology supports that renal denervation can treat hypertension and suggests that failures may be due to incomplete procedure. This research is highlighted as one of this month’s “best of the best” as part of the American Physiological Society’s APSselect program.

A small reduction in food intake—less than required to cause weight loss—dramatically slowed the development of a common genetic disorder called autosomal-dominant polycystic kidney disease (ADPKD) in mice, a new study in the American Journal of Physiology—Renal Physiology reports. There are no approved treatments for ADPKD in the U.S., and food reduction would be an ideal therapy because it most likely does not have side effects and is cost-effective, says the lead author.
Study May Explain Why Stroke Risk in Women Changes after Menopause
Overactive microglia—the brain’s immune cells—may worsen the damage from brain injury after stroke or head impact.
