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.

Men with erectile dysfunction sicker, less productive

A study spanning over 50,000 men from 8 countries shows that the presence of erectile dysfunction (ED) is a factor in poor productivity at work and decreased quality of life (QoL) with respect to health.

ED in this study was diagnosed based on the self-reported presence of any difficulty in producing or sustaining an erection in the 6 months preceding the survey. The severity was rated on a scale of 1 to 5, and those with a score of 2 or more were classified as having ED, compared to those with 1. The US figures were taken as an arbitrary standard against which the evaluations from other countries were compared.

Regular consumption of nuts improves sexual function

Researchers from the Human Nutrition Unit of the Universitat Rovira i Virgili (Tarragona/Spain) and the Pere Virgili Health Research Institute (IISPV) have found that consuming 60 grams of nuts a day improves sexual function. They have conducted the first nutritional intervention study with healthy participants of reproductive age in order to determine if regular consumption of nuts has any effect on sexual function. The analysis forms part of the FERTINUTS project, which has been created to assess the effects of regularly consuming nuts on the quality of semen.

Why sex becomes less satisfying with age

The number of women regularly having sex declines with age, and the number of women enjoying sex postmenopause is even lower. Although these facts are not surprising, the causes for these declines may be because previous research focused largely on biological causes only. However, a new study identifies psychosocial contributors.

Two new studies develop algorithms to identify patients at risk of acquiring HIV

Two new studies developed algorithms that can identify patients who are at risk of acquiring HIV and may benefit from preventive care. Both studies appear in the July 5 issue of The Lancet HIV.

Preexposure prophylaxis (PrEP) is an antiretroviral pill that is over 90% effective in preventing HIV acquisition when taken as prescribed. PrEP was recently given a Grade A recommendation from the U.S. Preventive Services Task Force but is vastly underutilized. There are nearly 40,000 new HIV infections annually in the United States, yet the Centers for Disease Control and Prevention estimates that only 7% of the 1.1 million individuals at substantial risk for HIV infection used the antiretroviral pill in 2016.
