The Impact Of Low-Carb Diets On The Kidneys

For years, experts have wondered and worried about the impact of low-carbohydrate, high-protein diets on the kidneys. Could they be harmful?

A recent study that will be published in the Clinical Journal of the American Society of Nephrology, answers that question: “No.”

Dr. Allon Friedman of the Indiana University School of Medicine and his colleagues compared the effects low-carbohydrate high-protein diet against a standard low-fat diet in 307 people without kidney disease in a two-year span. The researchers did not notice harmful effects on patients’ kidney function, fluid or electrolyte balance.

However, follow-up research is needed.


Urinary incontinence more prevalent after vaginal delivery

Women who deliver their babies vaginally have a greater chance of developing urinary incontinence than women who have caesarean births, says a Swedish study. The study also found that the incidence of urinary incontinence in women who delivered vaginally almost tripled after ten years when compared to women with C-sections.

Jump Start On Adulthood

KidsBoys starting puberty earlier

Boys in the U.S. are starting puberty six months to two years earlier, according to a new study by the American Academy of Pediatrics. The study found that on average boys now undergo the first signs of puberty between 9  and 10 years of age. The trend was more pronounced in African-American boys at 9.1 years, Hispanic boys at ten years and non-Hispanic white boys at 10.1 according to the online edition of the journal Pediatrics. The reason behind the early start is not known.   This is the first large study of puberty in U.S. boys in 25 years. In previous decades, the average age of puberty was 11.

How Aging Affects Male Sex Hormones

MaleIs there a male menopause?

Although there is no consensus whether there is a male menopause, medical experts agree that as men age they experience diminished hormone production.  But don’t call it ‘manopause.’ There’s no dramatic drop in hormone production as with women going through ‘the change,’ and men can continue to father children as octogenarians.

The medical term for this gradual and natural decline of the male, sex hormone testosterone is ‘andropause.’  But unlike menopause in women, andropause in men occurs over many years, and its impact is subtle.

However, some men experience a significant decline in testosterone levels resulting in a diminished sex drive, decreased muscle mass, fatigue and moodiness.

A simple blood test can check testosterone level. If testosterone levels are low, testosterone replacement therapy may be prescribed to help relieve symptoms. There are potential risks and side effects.

‘Grass’ Is Not Always Greener….

Marijuana may increase risk of testicular cancer

Researchers from the University of Southern California (USC) found a possible link between recreational marijuana use and testicular cancer.

USC researchers conducted a case-controlled study, which compares a group of people who have a certain disease with a group of similar people without the disease (the ‘control’ group). Specifically, they compared men who used marijuana and had testicular cancer to similar men without the disease.

The upshot? Pot smokers were twice as likely to develop testicular cancer. Although the small case-controlled study conducted by USC doesn’t prove that ‘lighting up’ causes the disease, it does support two earlier studies connecting marijuana use with testicular cancer. Collectively, it gives cause for concern.

Testicular cancer is the most common form of cancer in men 15 to 45 years of age.

Findings of the study were published online in the peer-reviewed journal of the American Cancer Society, Cancer.
