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 How does dopamine regulate both learning and motivation? (via sciencedaily.com) Original source
A new study brings together two schools of thought on the function of the neurotransmitter dopamine: one saying that dopamine provides a learning signal, the other saying that dopamine drives motivation.
Published Further link identified between autoimmunity and schizophrenia (via sciencedaily.com) Original source
Links have been reported between schizophrenia and proteins produced by the immune system that can act against one's own body, known as autoantibodies. Researchers have now identified autoantibodies that target a 'synaptic adhesion protein' in a subset of patients with schizophrenia. When injected into mice, the autoantibodies caused many schizophrenia-related changes.
Published Vitamin D alters developing neurons in the brain's dopamine circuit (via sciencedaily.com) Original source
Neuroscientists have shown how vitamin D deficiency affects developing neurons in the brain's dopamine circuit, which may lead to the dopamine dysfunction seen in adults with schizophrenia.
Published A special omega-3 fatty acid lipid will change how we look at the developing and aging brain (via sciencedaily.com) Original source
Scientists have found a lipid transporter crucial to regulating the cells that make myelin, the nerve-protecting sheath.
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 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 The drug fasudil is found to reverse key symptoms of schizophrenia in mice (via sciencedaily.com) Original source
Researchers used the drug fasudil to restore neurons and improve methamphetamine-induced cognitive dysfunction in a mouse model of schizophrenia.
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 Abnormal 12-hour cyclic gene activity found in schizophrenic brains (via sciencedaily.com) Original source
Researchers present the first evidence of 12-hour cycles of gene activity in the human brain. The study also reveals that some of those 12-hour rhythms are missing or altered in the postmortem brains of patients with schizophrenia.
Published Scientists link rare genetic phenomenon to neuron function, schizophrenia (via sciencedaily.com) Original source
Using state-of-the-art whole-genome sequencing and machine learning techniques, researchers conducted one of the first and the largest investigations of tandem repeats in schizophrenia, elucidating their contribution to the development of this devastating disease.
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 ADHD medication for amphetamine addiction linked to reduced risk of hospitalization and death, study finds (via sciencedaily.com) Original source
The ADHD medication lisdexamfetamine was associated with the lowest risk of hospitalization and death in people with amphetamine addiction, when medications generally used among persons with substance use disorders were compared, according to a new study.
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 Inflammation amplifies the effect of genetic risk variants for schizophrenia (via sciencedaily.com) Original source
Schizophrenia patients have fewer connections between nerve cells. This is believed to be caused by genetic risk variants leading to an excessive elimination of nerve cell connections by the immune cells of the brain. Researchers now report that the levels of protein from the relevant risk gene are elevated in first-episode patients and that inflammation further increases the expression of the risk gene.
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 Schizophrenia may increase dementia risk by 2.5 times (via sciencedaily.com) Original source
People with psychotic disorders such as schizophrenia are 2.5 times more likely than those without a psychotic disorder to eventually develop dementia, according to a new review.
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 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.
