Pharmaceuticals, personal care products could taint swimming pools

A new study suggests pharmaceuticals and chemicals from personal care products end up in swimming pools, possibly interacting with chlorine to produce disinfection byproducts with unknown properties and health effects. Researchers detected DEET, the active ingredient in insect repellants; caffeine; and tri(2-chloroethyl)-phosphate (TCEP), a flame retardant in some swimming pools. Some chemicals are volatile, which means they can escape into the air to be inhaled. Others can be ingested or absorbed through the skin.

Exercise allows you to age optimally

Staying active allows you to age optimally, according to a study. The study of amateur older cyclists found that many had levels of physiological function that would place them at a much younger age compared to the general population; debunking the common assumption that aging automatically makes you more frail.

eLearning as good as traditional training for health professionals

Electronic learning could enable millions more students to train as doctors and nurses worldwide, according to research.

Playing catch can improve balance, prevent falls in seniors

The simple training exercise of catching a weighted medicine ball can improve balance and may help prevent falls in the elderly, according to research.

Bring Back Asylums?

One of psychiatry’s so-called triumphs was the discovery of antipsychotics (starting with chlorpromazine in the 1950s) and the ensuing release of the seriously mentally ill into the community. State hospitals were rapidly evacuated, and patients supplied with the new “miracle drugs” were relabeled as “clients” or “consumers” as if they did not have severe medical illnesses. Asylums that had offered medical care, refuge, and safety were condemned to the trash heap of psychohistory.

Effect of Three Decades of Screening Mammography on Breast-Cancer Incidence

“Despite substantial increases in the number of cases of early-stage breast cancer detected, screening mammography has only marginally reduced the rate at which women present with advanced cancer. Although it is not certain which women have been affected, the imbalance suggests that there is substantial overdiagnosis, accounting for nearly a third of all newly diagnosed breast cancers, and that screening is having, at best, only a small effect on the rate of death from breast cancer.”

Long-term use of hormonal contraceptives is associated with an increased risk of a rare brain tumor, study finds

Taking a hormonal contraceptive for at least five years is associated with a possible increase in a young woman’s risk of developing a rare tumor, glioma of the brain. This project focused on women aged 15-49 years and the findings are published in the British Journal of Clinical Pharmacology.

Telomere extension turns back aging clock in cultured human cells, study finds

A new procedure can quickly and efficiently increase the length of human telomeres, the protective caps on the ends of chromosomes that are linked to aging and disease, according to scientists.

Higher dementia risk linked to more use of common drugs

http://www.sciencedaily.com/releases/2015/01/150126124721.htm

A large study links a significantly increased risk for developing dementia, including Alzheimer’s disease, to taking commonly used medications with anticholinergic effects at higher doses or for a longer time. Many older people take these medications, which include nonprescription diphenhydramine (Benadryl).
