Researchers have found that penguins from the Punta Tombo reserve in southern Argentina travel more than 300 miles to find food, a significant increase from previously thought foraging ranges. The depletion of squid and other preferred foods is attributed to commercial fisheries and climate change.
The study found a 38% decrease in asthma symptoms and a 31% increase in child quality of life. Parents also experienced a 16% increase in perceived competence of managing their child's illness. The program used a multi-disciplinary approach to help patients control their disease.
A new study by Johns Hopkins Medicine recommends reducing the annual frequency of prostate-specific antigen (PSA) testing for men between 50 and 70 years old, as most don't need frequent tests to detect curable cancers. The guidelines suggest PSA testing every two years is sufficient to identify most men with curable prostate cancer.
The study estimates ecosystem services' value between $16 and $54 trillion per year, with coastal environments accounting for 43% of this value. The research highlights the importance of valuing ecosystem services in decision-making processes.
The newly revised nomograms combine clinical stage, Gleason score, and PSA level information to identify men who can be cured by surgery alone. The use of these nomograms should improve our ability to predict surgical curability and help patients make informed treatment decisions.
Researchers have discovered that HIV can invade cells within any female reproductive tract organ, increasing the risk of infection. The study's findings suggest that vaccine development and disease prevention should aim to confer protection throughout the entire tract.
A new study by Washington University School of Medicine researchers found that a surprising 22 percent of men with prostate cancer had PSA levels between 2.6 and 4, highlighting the need for yearly PSA tests for men over 50. The study suggests that doctors may be missing cancers in this range due to outdated guidelines.
Researchers have discovered a key role for the TIGR protein in non-hereditary forms of glaucoma, which may lead to novel diagnostic tools and treatments. The study found that exposure to steroid drugs or oxidative stress increased TIGR protein production, contributing to elevated intraocular pressure.
A new laparoscopic technique for kidney removal has been shown to reduce pain, hospital stays, and recovery time compared to traditional methods. The study found that kidneys removed with this technique function as well as those taken out with a large incision.
A study funded by NIMH found that only 23.5% of women in jail needed mental health services received them, despite having special needs such as abuse and addiction. The lack of services can lead to increased suicide rates among female detainees.
