• Cigarette Smoke Exposure Increases Scar Tissue in the Kidney and Heart, Study Finds:  Smoking may lead to fibrosis in the heart and kidneys and can worsen existing kidney disease, according to a new study published in Physiological Genomics. The research team suggests that exposure to cigarette smoke negatively affects genetic messaging that controls tissue scarring.
  • 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. The research team observed that healthy volunteers had greatly reduced numbers of certain T cell subsets within three hours of falling asleep. While it’s unclear where the T cells go during sleep, the researchers have some guesses to where and why they migrate.
