Nearly 80,000 people die as a result of drinking alcohol each year in North and Latin America, according to a new study published Tuesday in the Journal Addiction.
Researchers looked at alcohol as the cause of death by examining death certificates, over a two-year period in 16 North and Latin American countries. Men accounted for 84% of alcohol-related deaths.
Maristela Monteiro, study author and a senior advisor on alcohol and substance abuse at the Pan American Health Organization, says people are drinking too much and "it's killing people before they should be dying."
"These deaths are all 100 percent preventable," she says. FULL POST

It’s become the hot new treatment for older men. “T,” or testosterone replacement therapy, has been touted as the new way to turn back a man’s body clock and improve his sexual performance.
But there may be trouble in paradise, according to new research. In a study published this week in the Journal of the American Medical Association, scientists have found that men taking testosterone therapy had a 29% greater risk of death, heart attack and stroke than those who were not on the hormone replacement.
The study included 8,709 men with low testosterone levels, who underwent coronary angiography, a procedure used to open narrow or blocked coronary arteries, in the Veterans Affairs (VA) system between 2005 and 2011. Some were found not to have blockages.
Researchers found the number of patients experiencing heart problems such as attacks and strokes three years after their angiographies, was 19.9% for those who were not on testosterone and 25.7% for those who were. Even when scientists accounted for other factors in the patients’ health, the increase of heart events in those on testosterone therapy was significant, according to the study.

The quality of a man's semen is directly related to his ability to help conceive a child. But science hasn't found many solutions for men looking for a baby-making boost. Now a study suggests men who are hoping to start families may want to pay attention to what they eat.
A study presented at the American Society for Reproductive Medicine in Boston this week, and published in the journal Fertility and Sterility, suggests that processed meat intake is linked to poorer semen quality, and fish is linked to better semen quality.
Myriam Afeiche, research fellow at the Harvard School of Public Health, and her colleagues looked at how types of meat could be associated with semen quality. They took samples from 156 men at the Massachusetts General Hospital Fertility Center in Boston and had the men answer a questionnaire about their eating habits.

Being married may significantly improve the likelihood of surviving cancer, researchers say.
In a new study of more than 700,000 people with diagnoses of the most deadly cancers in the United States, patients who were married were more likely to detect their disease early, receive potentially curable treatments and live longer. The study was published in the Journal of Clinical Oncology.
The researchers observed a 20% reduction in deaths among the patients who were married compared to unmarried patients - a benefit bigger than several kinds of chemotherapy used for treating cancer.

Semen quality is a much-discussed subject among scientists these days. Data suggests sperm concentration has been declining in Western countries over the past couple of decades - and reasons for the decline are debatable.
The lead author of a new study on the subject, Audrey Gaskins, has been studying the effects of diet and exercise on semen for several years as a doctoral candidate at the Harvard School of Public Health. Her latest research shows a lack of physical activity – and too much time in front of the television - may impact sperm count and concentration.
Previous studies have shown a link between physical activity and decreased levels of oxidative stress, Gaskins says. “Oxidative stress” is stress placed on the body as it tries to get rid of free radicals or repair the damage caused by them. Exercise may protect certain male cells from oxidative damage, Gaskins says, leading to increased sperm concentration.
Those findings led Gaskins to complete an observational study on young men’s exercise and TV habits as they relate to semen quality. The results were published online Monday in the British Journal of Sports Medicine.

Taking a multivitamin may help prevent cancer in healthy middle-aged men, according to a new study published Wednesday in the Journal of the American Medical Association.
Scientists at Brigham and Women's Hospital and Harvard Medical School recruited nearly 15,000 male physicians, 50 years or older, and followed them for more than a decade. Half took the daily multivitamin Centrum Silver; the others took a placebo.
Men in the vitamin group had a modest 8% reduction in cancer cases compared to the others.
"This study suggests, at least for men, that there might be benefits to taking multivitamins in terms of cancer,” study author Dr. John Michael Gaziano said in a press release. He is the chief of the Division of Aging at Brigham and Women’s Hospital.

A 61-year-old Army veteran is suing the U.S. government for $10 million, claiming negligent care resulted in severe frostbite on his penis, leading to its partial amputation.
Michael D. Nash of Louisville, Kentucky, filed suit in federal court Monday. He is asking for damages for what his lawyer calls "significant mental and emotional distress and trauma as a result of his injuries."
In October 2010, Nash underwent surgery at the VA Medical Center in Lexington, Kentucky. Doctors were removing and replacing a malfunctioning penile implant. After the surgery, according to court documents, a nurse applied ice packs to Nash's penis to reduce pain and swelling. FULL POST

It was hard to keep track of all the superheroes hitting the big screen this summer: Batman in "The Dark Knight Rises." Iron Man, The Hulk, Captain America and Thor in "The Avengers." Peter Parker in "The Amazing Spider-Man."
And each character seemed to have bulked up for their latest comeback.
"Over the last few decades, superheroes' bodies have become extremely muscular with body dimensions that are impossible for most men to attain," write the authors of a new study that analyzes the effects of superheroes on male body image.
Past research has shown that seeing muscular figures can make men feel badly about their own bodies, similar to the way seeing stick-thin supermodels can make women question their weight.
But the same effect may not hold true for our favorite comic book characters. FULL POST

As the number of American parents increasingly leave their baby boys uncircumcised, HIV and other sexually transmitted disease rates are likely to climb, according to researchers from Johns Hopkins University, and the costs associated with those diseases could reach into the billions.
"The medical benefits of male circumcision are quite clear," said Dr. Aaron Tobian, an assistant professor of pathology at Johns Hopkins and lead author of the study published Monday in the Archives of Pediatric and Adolescent Medicine. "But while the medical evidence has been increasingly more positive, male circumcision rates in the U.S. have been decreasing."
Specifically, he says, circumcision rates had been fairly stable in the 1970s, at about 79%. By 1999, he says less than 63% of boys had the procedure, and by 2010, the rate had dropped to 55%.

Only one in 500 Americans is a black gay or bisexual male, but black men who have sex with men (MSM) account for one in four new HIV infections in the United States, according to a new report by the Black AIDS Institute (BAI).
Just days away from the first International AIDS Conference to be held on U.S. soil in 22 years, the BAI, a national think tank focused on African-Americans, released a somber account detailing how the virus continues to disproportionately infect and kill young black men who have sex with other men.
