Published Double risk of dementia after mouth ulcer virus (via sciencedaily.com) Original source
People who have had the herpes virus at some point in their lives are twice as likely to develop dementia compared to those who have never been infected. A new study confirms previous research on whether herpes can be a possible risk factor for dementia.
Published Higher infant mortality rates associated with restrictive abortion laws, study finds (via sciencedaily.com) Original source
New research provides evidence that U.S. states with the most restrictive abortion laws saw 16 percent more infant deaths in 2014-2018 than in states offering access to comprehensive reproductive healthcare.
Published Genetic variants underlying male bisexual behavior, risk-taking linked to more children, study shows (via sciencedaily.com) Original source
Because same-sex sexual behavior does not result in offspring, evolutionary biologists have long wondered how the genes associated with this behavior have persisted in the human genome, and whether they will remain in the future. A new study suggests that part of the explanation -- specifically for male bisexuals -- has to do with risk-taking behavior.
Published Genetic mutations that promote reproduction tend to shorten human lifespan, study shows (via sciencedaily.com) Original source
A study based on a review of genetic and health information from more than 276,000 people finds strong support for a decades-old evolutionary theory that sought to explain aging and senescence.
Published Hormonal contraceptives in teens may alter risk assessment, rat study suggests (via sciencedaily.com) Original source
Hormonal contraceptives taken by adolescents may influence development of the brain in a way that alters the recognition of risks, a new study in rats suggests.
Published Blood clotting risk quickly drops after stopping hormonal contraceptives (via sciencedaily.com) Original source
Using birth control pills and other hormone-based contraceptives is known to elevate the risk of blood clots, but a new study suggests that this risk largely goes away within two to four weeks after one stops using these contraceptives. The findings can help patients and doctors weigh the benefits and risks of hormonal contraceptives and guide when to stop using them ahead of events that could further increase the risk of dangerous clots, such as major surgery, prolonged periods of immobility, or when tapering anticoagulant medications after a blood clot.
Published Contraceptive pill users less likely to report depression (via sciencedaily.com) Original source
A new study has shown that women who are taking the oral contraceptive pill are less likely to report depression. The research, which analysed data from 6,239 women in the United States aged 18-55 years old, found that the prevalence of major depression amongst users of the oral contraceptive pill (OCP) was significantly lower, at 4.6%, compared to former OCP users (11.4%).
Published Morning-after pill more effective when taken with an anti-inflammatory painkiller, researchers find (via sciencedaily.com) Original source
A research team recently published findings on adding an anti-inflammatory painkiller used for arthritis pain to an oral emergency contraceptive pill (also known as the morning-after pill) to increase the effectiveness of pregnancy prevention.
Published Syphilis transmission networks and antimicrobial resistance in England uncovered using genomics (via sciencedaily.com) Original source
Scientists use genomics to uncover syphilis transmission patterns in England, in a pioneering new approach for STI surveillance.
Published New study shows effectiveness of mpox vaccine (via sciencedaily.com) Original source
A new international study has shown mpox (formerly known as monkeypox) infections to be less severe among those who are vaccinated or had a previous infection in 2022, underlining the importance and effectiveness of vaccination.
Published Birth-control pills affect the body's ability to regulate stress, study suggests (via sciencedaily.com) Original source
A new study suggests that birth-control pills negatively impact women's stress response.
Published New study links contraceptive pills and depression (via sciencedaily.com) Original source
Women who used combined contraceptive pills were at greater risk of developing depression than women who did not, according to a new study. Contraceptive pills increased women's risk by 73 per cent during the first two years of use.
Published Low sexual satisfaction linked to memory decline later in life (via sciencedaily.com) Original source
Low sexual satisfaction in middle age may serve as an early warning sign for future cognitive decline, according to a new study. The study, which tracked associations between erectile function, sexual satisfaction and cognition in hundreds of men aged 56 through 68, found that declines in sexual satisfaction and erectile function were correlated with future memory loss.
Published Tuberculosis disease intensifies HIV antibody response in people with HIV (via sciencedaily.com) Original source
New research found that people living with HIV that have had pulmonary tuberculosis had broader and more potent HIV antibody responses and differences in HIV sequences predicted to be antibody resistant as compared to those without suspected or documented tuberculosis.
Published New genetic target for male contraception identified (via sciencedaily.com) Original source
Discovery of a gene in multiple mammalian species could pave the way for a highly effective, reversible and non-hormonal male contraceptive for humans and animals. Researchers identified expression of the gene, Arrdc5, in the testicular tissue of mice, pigs, cattle and humans. When they knocked out the gene in mice, it created infertility only in the males, impacting their sperm count, movement and shape.
Published Smells influence metabolism and aging in mice (via sciencedaily.com) Original source
Exposure to female odors and pheromones causes weight loss and extend the life spans of mice, which may have implications for humans, researchers have found. While it was already known that sensory cues in humans and animals influence the release of sex hormones, this study shows that these cues could have more wide-spread physiological effects on metabolism and aging.
Published A readily available dietary supplement may reverse organ damage caused by HIV and antiretroviral therapy (via sciencedaily.com) Original source
MitoQ, a mitochondrial antioxidant that is available to the public as a diet supplement, was found in a mouse study to reverse the detrimental effects that HIV and antiretroviral therapy (ART) have on mitochondria in the brain, heart, aorta, lungs, kidney and liver.
Published Study finds similar association of progestogen-only and combined hormonal contraceptives with breast cancer risk (via sciencedaily.com) Original source
There is a relative increase of 20% to 30% in breast cancer risk associated with both combined and progesterone-only contraceptives, whatever the mode of delivery, though with five years of use, the 15-year absolute excess incidence is at most 265 cases per 100,000 users, according to a new study.
Published High infant mortality rates and global human population rise (via sciencedaily.com) Original source
New research showing high infant mortality rates are contributing to an incessant rise of the global human population supports arguments for greater access to contraception and family planning in low- and middle-income nations.
Published On-demand male contraceptive shows promise in preclinical study (via sciencedaily.com) Original source
An experimental contraceptive drug temporarily stops sperm in their tracks and prevents pregnancies in preclinical models. The study demonstrates that an on-demand male contraceptive is possible.
