New link between two important products of nitric oxide discovered

Ever since three US-based researchers working independently unveiled the role of nitric oxide in mediating blood vessel dilation, endothelial cell contraction and smooth muscle relaxation, their discoveries have served as a basis for novel treatments for high blood pressure and erectile dysfunction, among other conditions.

The Nobel Prize in Physiology or Medicine in 1998 was awarded jointly to Robert F. Furchgott, Louis J. Ignarro and Ferid Murad for groundbreaking research of nitric oxide conducted during the 1970s and 1980s. Their work paved the way for the development of redox biochemistry, an entirely new research field. Nitric oxide is a free radical that has been shown to play a key role in the body’s defenses against tumors and bacteria, as well as in inflammatory and wound healing processes.

Web-based, digital-app birth control prescription services appear to be overall safe and efficient

Web-based and digital-app services that offer oral contraception appear to be overall safe and efficient, according to the findings of a secret-shopper-style study conducted by researchers at Harvard Medical School and UC Davis that analyzed the birth control prescription services of nine U.S. vendors.

The results, published Sept. 26 in The New England Journal of Medicine, offer a measure of reassurance amid concerns over the safety and reliability of a rapidly growing model of care delivery that gives individuals online access to treatments ranging from birth control and erectile dysfunction medication to hair-loss drugs.

Men with prostate cancer want access to female doctors

Sep 25 2019

Malecare, America’s largest men’s cancer support network, this week announced the world’s first prostate cancer patient conference to feature an all-female faculty featuring twelve of the U.S.A.’s top prostate cancer clinicians. The Prostate Cancer Patient Conference is a day-long event taking place in New York City on October 5th.

Less than 1% of all urologists are women who treat prostate cancer. Sexism in cancer care is a barrier for patients seeking optimal care. Malecare is trying to reduce this disparity, starting with this groundbreaking conference. Female doctors tend to listen more attentively to their male patients, according to men in our support groups. It’s possible that female doctors feel less competitive and more compassionate towards men suffering the side effects of prostate cancer treatment.”

Oldies who have sex happier and healthier, says new study

Who says sex is just for younger people? A new study gives this popular belief the lie, showing that while older people may have less frequent sex, it is still important for their happiness and physical health.

Neither do they lack the motivation or physical capability, as many think. The study titled, ‘Sexual Activity is Associated with Greater Enjoyment of Life in Older Adults’, is published in the journal Sexual Medicine.

Men with prostate cancer can have healthy sex lives after surgery

There’s a perception that surgery to treat prostate cancer will spell the end of a man’s sex life.

And while that often used to be the case, survivorship programs, like the one at the University of Michigan Rogel Cancer Center, offer counseling and interventions to promote sexual recovery after cancer treatment.

“Prostate cancer, especially if it’s caught early, is a highly treatable disease,” says Daniela Wittmann, Ph.D., LMSW, an associate professor of urology and social work at U-M, and a certified sex therapist with more than 30 years of experience. “But that also means that men are often living for a long time and dealing with the side effects of treatment.”

Purveyors of black-market pharmaceuticals target immigrants

The bootleg medications were smuggled across the border and sold to mostly Latino immigrants in public spaces throughout Los Angeles — at swap meets, parks, beauty salons and makeshift stands outside mom-and-pop grocery stores.

The drugs were cheap, and the customers — mostly from Mexico and Central America — did not need prescriptions to buy them. Some of the products featured brand names and colorful packaging that immigrants knew well from their home countries — including Ciprofloxacina, a potent antibiotic, and Dolo Nervi Doce — translated as “Pain Nerve 12” — an injectable B-complex vitamin taken for fatigue.

Gold nanoparticles used successfully in prostate tumour trial

Researchers at the Icahn School of Medicine, Mount Sinai, New York have reported a pilot clinical trial with a “nanoparticle-based photothermal cancer therapy” for prostate cancers. Their work with this targeted therapy is published in a study titled, “Gold nanoshell-localized photothermal ablation of prostate tumors in a clinical pilot device study,” in the latest issue of the journal Proceedings of National Academy of Science.

Art Rastinehad, DO, Associated Professor of Urology and Radiology at the Icahn School of Medicine at Mount Sinai, is leading the first clinical trial of gold nanoparticles to treat prostate cancer.

Gold nanoparticles shown to safely, effectively ablate low- to intermediate-grade prostate tumors

Biocompatible gold nanoparticles designed to convert near-infrared light to heat have been shown to safely and effectively ablate low- to intermediate-grade tumors within the prostate, according to a study conducted at the Icahn School of Medicine and published in the journal Proceedings of the National Academy of Sciences. This treatment could offer patients a targeted therapy option that would preserve critical structures within the prostate, thus avoiding side effects associated with whole-gland treatment such as prostatectomies.

Mysterious vaping lung injuries may have flown under regulatory radar

It was the arrival of the second man in his early 20s gasping for air that alarmed Dr. Dixie Harris. Young patients rarely get so sick, so fast, with a severe lung illness, and this was her second case in a matter of days.

Then she saw three more patients at her Utah telehealth clinic with similar symptoms. They did not have infections, but all had been vaping. When Harris heard several teenagers in Wisconsin had been hospitalized in similar cases, she quickly alerted her state health department.

Research reveals link between concussions and erectile dysfunction in former NFL players

Former professional football players who have experienced concussion symptoms, including loss of consciousness, disorientation or nausea after a head injury, are more likely to report low testosterone and erectile dysfunction (ED), according to research published Aug. 26 in JAMA Neurology.

The research–based on a survey of more than 3,400 former NFL players representing the largest study cohort of former professional football players to date–was conducted by investigators at the Harvard T.H. Chan School of Public Health and Harvard Medical School as part of the ongoing Football Players Health Study at Harvard University, a research program that encompasses a constellation of studies designed to evaluate various aspects of players’ health across their lifespans.
