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 Elimination of type of bacteria suggests treatment for endometriosis (via sciencedaily.com) Original source
A research group has discovered that using an antibiotic to target Fusobacterium, a common bacterium that causes inflammation, improved the symptoms of endometriosis. Their findings suggest an alternative treatment for the disease.
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 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 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 Dynamic expression of brain serotonin receptors across the menstrual cycle provides clues about premenstrual dysphoric disorder (via sciencedaily.com) Original source
A new study explores the interplay between the serotonin system and estradiol in the brain, showing that the central nervous system in patients with premenstrual dysphoric disorder (PMDD) seems to increase serotonin transporter density from the periovulatory phase (when estradiol levels are high) to premenstrual cycle phase (when both estradiol and progesterone are decreasing). The findings have the potential to advance the clinical treatment of PMDD.
Published Migraines during menstruation: Low estrogen levels paired with higher CGRP levels may jump start migraine (via sciencedaily.com) Original source
As estrogen levels fluctuate, a new study has found for female participants with migraine, their levels of the protein calcitonin gene-related peptide (CGRP) that plays a key role in starting the migraine process also fluctuate.
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.
Published Does lifetime exposure to estrogen affect risk of stroke? (via sciencedaily.com)
People with a higher cumulative estrogen exposure throughout their life may have a lower risk of stroke, according to a new study. The lower risk was found for both ischemic stroke and intracerebral hemorrhage.
Published Birth choices after previous cesarean and risk of pelvic floor surgery (via sciencedaily.com) Original source
Vaginal birth after a previous cesarean section is associated with an increased risk of pelvic floor surgery compared with planning another cesarean, according to a new study. The findings provide useful information to help women who have had a previous cesarean section when planning how to give birth in their next pregnancy.
Published Challenging guidelines on pregnancy interval following miscarriage or abortion (via sciencedaily.com) Original source
Conception within three months of a miscarriage or an abortion is not associated with increased risks of adverse pregnancy outcomes, according to new research. The study suggests that, contrary to current advice, women could attempt pregnancy after a previous miscarriage or induced abortion without elevated perinatal risks and reassures those who want to try again sooner than guidelines recommend.
Published How hormonal birth control may affect the adolescent brain (via sciencedaily.com)
One aspect of hormonal contraceptives' effect on the teenage body remains a mystery -- whether and how they modify the developing brain. New research in young rats links synthetic hormones found in birth control pills, patches and injections with disordered signal transmission between cells in the prefrontal cortex, an area of the brain that continues to develop throughout adolescence.
Published Model shows where women lost access to abortion after Dobbs (via sciencedaily.com) Original source
A third of American women of reproductive age now face excessive travel times to obtain an abortion, according to a new geospatial analysis by researchers in San Francisco and Boston that is one of the first to model the effects of the Supreme Court's recent Dobbs v. Jackson decision.
Published Fungal association with tumors may predict worse outcomes (via sciencedaily.com)
The presence of some fungal species in tumors predicts -- and may even help drive -- worse cancer outcomes, according to a new study.
Published Continued access to fertility preservation critical for adolescent and young adult cancer patients, following SCOTUS decision, experts say (via sciencedaily.com) Original source
New findings show more than 32,000 newly diagnosed adolescent and young adult (AYA) cancer patients may lose or face compromised fertility preservation care each year due to legislation that has been enacted or is expected to be enacted in some states.
Published Advanced imaging sheds light on immune escape of shape-shifting fungus (via sciencedaily.com) Original source
Fungal pathogens have a major global impact upon human health -- they are often difficult to diagnose and treat, and there is an urgent need for better diagnostics and more effective antifungal treatments. Using newly developed imaging technologies, researchers have now revealed how Candida albicans, a common fungus, evades immune responses. According to the researchers this involves an 'alien-like' shape shifting that allows the fungus to break out of immune cells.
Published Combined birth control pill linked with increased risk of blood clots in obese women (via sciencedaily.com)
Obese women who use oral contraceptives containing estrogen and progestin have a 24-fold increased risk of venous thromboembolism (VTE) compared with non-obese women not using the drugs, according to a new article.
Published Data on cancer risk from hormone therapy 'reassuring,' menopause experts say (via sciencedaily.com) Original source
A new scientific paper and other recent evidence offer important reassurances about the risk of breast cancer from hormone therapy to treat menopause symptoms, two menopause experts say.
Published Body posture affects how oral drugs absorbed by stomach (via sciencedaily.com) Original source
A common method of administering drugs is orally, by swallowing a pill or capsule. But oral administration is the most complex way for the human body to absorb an active pharmaceutical ingredient, because the bioavailability of the drug in the gastrointestinal tract depends on the medication's ingredients and the stomach's dynamic physiological environment. Researchers have now employed a biomimetic in-silico simulator based on the realistic anatomy and morphology of the stomach -- a 'StomachSim' -- to investigate and quantify the effect of body posture and stomach motility on drug bioavailability.
