Adult depression has long been associated with shrinkage of the hippocampus, a brain region that plays an important role in memory and response to stress. Now, new research from Washington University in St. Louis has linked participation in team sports to larger hippocampal volumes in children and less depression in boys ages 9 to 11.
Seven types of bacteria and certain immune factors in a woman's vagina and cervix may be responsible for increasing the risk of spontaneous preterm birth (sPTB) or protect against it, according to a new study from the Perelman School of Medicine at the University of Pennsylvania and the University of Maryland School of Medicine. Results of the study provide groundbreaking information that the authors suggest could help physicians better predict preterm birth, especially for African-American women early in pregnancy.
A single allergic reaction during pregnancy prompts sexual-development changes in the brains of offspring that last a lifetime, new research suggests. Female rats born to mothers exposed to an allergen during pregnancy acted more characteristically 'male' -- mounting other female rodents, for instance -- and had brains and nervous systems that looked more like those seen in typical male animals.
It is important to understand and prevent unethical behavior in working life. Leaders should be able to take responsibility for challenging situations and show commitment to moral values. A recent study at the University of Jyvaskyla charted the different moral identity statuses among Finnish leaders.
Doctors should think carefully before testing patients for a urinary tract infection (UTI) to avoid over-diagnosis and unnecessary antibiotic treatment, according to updated asymptomatic bacteriuria (ASB) guidelines released by the Infectious Diseases Society of America (IDSA) and published in Clinical Infectious Diseases.
Children have high perceptions of motor skills. Some gender differences were identified: girls better in locomotor skills, boys have higher perception and actual skills in ball skills.
A UCLA-led study confirms what women approaching menopause have long suspected: menopause does make fat go up. The study finds that women undergoing perimenopause lost lean body mass and more than doubled their fat mass. The research demonstrates that body mass index (BMI) is a very important clinical tool for predicting health events, such as getting diabetes or having cardiovascular disease -- but is a less useful gauge of cardio-metabolic risk in older women.
In a first, researchers at the University of Pittsburgh School of Medicine and the Magee-Womens Research Institute have reported in a non-human primate model that immature testicular tissue can be cryopreserved, and later be used to restore fertility to the same animal.
From 1999 to 2017, 38,942 US children ages 5 to 18 years old were killed by firearms, averaging more than 2,000 deaths a year. In 2017 alone, 2,462 school-age children were killed by firearms compared to 144 police officers and 1,000 active military worldwide who died in the line of duty. The study finds significant increases that began with an epidemic in 2009, followed by another one in 2014. Each of these epidemics has continued through 2017.
Through simple games and day-to-day tasks, parents can help their children learn self-regulation, a skill considered essential for success, a University of Otago, New Zealand, study has found.
