Does spaceflight increase men’s risk of erectile dysfunction?

2023-11-22
(Press-News.org) During missions into space, astronauts are exposed to high levels of galactic cosmic radiation and weightlessness. Simulation experiments in male rats indicated that these aspects of spaceflight can negatively affect vascular tissues relevant to erectile dysfunction, even after a period of long-term recovery.

The research, which is published in The FASEB Journal, indicated that vascular alterations are induced by relatively low doses of galactic cosmic radiation and to a lesser extent simulated weightlessness, primarily through increases in oxidative stress. Treatment with different antioxidants could counter some of these effects.

“With manned missions to outer space planned for the coming years, this work indicates that sexual health should be closely monitored in astronauts upon their return to Earth,” said corresponding author Justin D. La Favor, PhD, of Florida State University. “While the negative impacts of galactic cosmic radiation were long-lasting, functional improvements induced by acutely targeting the redox and nitric oxide pathways in the tissues suggest that the erectile dysfunction may be treatable.”

What are the effects of workforce automation across race and gender in the United States?

2023-11-22
Advances in areas such as robotics and artificial intelligence enable the automation of a range of occupational tasks, leading to fundamental changes in the nature of work. New research published in The American Journal of Economics and Sociology indicates that the effects of job automation vary across race and gender, and without targeted interventions, will likely result in increasing inequality. The research analyzes two distinct measures of automation job displacement risk for more than 1.4 million Americans across 385 occupations. The findings show that the intersection of race and gender has a significant effect on automation risks. For example, ...

Has the COVID-19 pandemic compromised bone health?

2023-11-22
Results from a study published in the American Journal of Human Biology suggest that the COVID-19 pandemic has had negative effects on bone tissue—including both bone mineral density in the forearm and total bone mineral content. The study by investigators at Comenius University, in Slovakia, included 387 young adults whose bone health measurements were taken prior to the COVID-19 pandemic and 386 whose measurements were taken from September 2020 to November 2022 during the pandemic. Individuals participated in the study only once, either before or during the pandemic. Certain lifestyle changes during the pandemic may have contributed ...

Does stem cell transplantation benefit patients with knee osteoarthritis?

2023-11-22
Cell therapy represents a potential regenerative treatment for osteoarthritis. A recent analysis of all relevant published studies indicates that stem cell transplantation from different sources is effective for treating knee osteoarthritis, the most prevalent chronic joint disease. The review and meta-analysis, which is published in the Journal of Orthopaedic Research, included 16 studies involving 875 patients with knee osteoarthritis (441 in the stem cell transplantation group and 434 in the control group). Stem cell treatment was associated with significant reductions in patient-reported pain from the third month onwards. The most significant pain relief at different postoperative months ...

Can sound stimulation lessen long-term concussion symptoms?

2023-11-22
New research indicates that acoustic stimulation of the brain may ease persistent symptoms in individuals who experienced mild traumatic brain injury in the past. The study, which is published in Annals of Clinical and Translational Neurology, included 106 military service members, veterans, or their spouses with persistent symptoms after mild traumatic brain injury 3 months to 10 years ago. Participants were randomized 1:1 to receive 10 sessions of engineered tones linked to brainwaves (intervention), or random ...

Experts urge a united global vision, definitions and targets for ‘responsible sourcing’ of minerals needed for green transition

Experts urge a united global vision, definitions and targets for ‘responsible sourcing’ of minerals needed for green transition
2023-11-22
Experts have delivered a sweeping prescription to governments, civil society and industry for a globally coordinated approach to the responsible sourcing of raw materials needed to achieve a circular green economy. In a report, the four-year EU-funded RE-SOURCING project proposes adopting the global vision of a circular economy and reduced resource consumption by 2050 and outlines a series of interim milestones and targets for three key industrial sectors: renewable energy, mobility, and electric and electronic equipment.  The report (at https://bit.ly/3uqXlqT from ...

Rise in people discovered dead and decomposed raises concerns

2023-11-22
An exploratory study has raised concerns about the increasing number of people in England and Wales whose bodies are discovered so late that they have decomposed. The study, published in the Journal of the Royal Society of Medicine, has highlighted potential links between growing isolation and such deaths, even before the COVID-19 pandemic. The study was authored by a team led by Dr Lucinda Hiam of the University of Oxford and including histopathology registrar Dr Theodore Estrin-Serlui of Imperial College NHS Healthcare Trust. The researchers analysed data from the Office for ...

Obesity may not be the only factor to link ultra-processed foods to higher risk of mouth, throat and oesophagus cancers

2023-11-22
Eating more ultra-processed foods (UPFs) may be associated with a higher risk of developing cancers of upper aerodigestive tract (including the mouth, throat and oesophagus), according to a new study led by researchers from the University of Bristol and the International Agency for Research on Cancer (IARC).  The authors of this international study, which analysed diet and lifestyle data on 450,111 adults who were followed for approximately 14 years, say obesity associated with the consumption of UPFs may not be the only factor to blame. The study is published today [22 November] in the European Journal of Nutrition. Several ...

Immunotherapy drug is well tolerated in lung cancer patients with limited physical function, study suggests

Immunotherapy drug is well tolerated in lung cancer patients with limited physical function, study suggests
2023-11-22
For patients with advanced or metastatic non-small cell lung cancer (NSCLC) and limited performance status, an immune checkpoint inhibitor drug called durvalumab is safe and may benefit overall survival, according to a new eClinicalMedicine study by UPMC Hillman Cancer Center researchers. Performance status, a measure of a patient’s physical function and ability to perform daily activities, is often assessed with the Eastern Cooperative Oncology Group (ECOG) score on a scale of 0 to 5. Higher values describe patients who spend more time confined to a bed or chair and have less ability to care for themselves. Many clinical ...

Strip searching a child without appropriate consent is “sexual abuse,” insists expert

2023-11-22
Strip searching a child without appropriate consent is “sexual abuse,” and should attract heavy sanctions—backed up by legislation—for any UK police officer who does it, insists a leading paediatrician in an opinion piece, published online in the Archives of Disease in Childhood. Unless the officer(s) can legitimately justify their actions to an independent panel, they should be instantly dismissed and compelled to sign the Sex Offenders Register, writes paediatrician Professor Andy Bush of Imperial College, London. He cites the “shocking number” of children ...
