A new study published in Liver Transplantation found that pediatric liver transplant recipients are at increased risk of graft loss and death from adult organ donors who are severely obese. However, the study also suggests that a BMI of 25-35 kg/m2 is not associated with an increased risk of mortality in this population.
A study by Esther Kim found that commuters use various tactics to avoid sitting next to others, including pretending to be busy or checking phones. The primary concern is not the background characteristics of fellow passengers but rather personal comfort and safety.
The study found that without PSA testing, approximately 25,000 cases of advanced prostate cancer would occur in 2008, three times the actual number observed. This would result in more men experiencing aggressive disease with limited treatment options.

Researchers found that RA patients primarily cite joint pain as the reason for their perceived change in disease activity, while physicians emphasize swollen joints. The study's results suggest a discrepancy between patient and physician perceptions of disease activity, with potential implications for improved shared decision-making.
A survey of all 24 Scottish intensive care units found that a quarter of admissions were alcohol related, particularly among men and younger people. Patients with alcohol problems required longer ventilation times and had higher estimated annual costs.
Teenage girls with eating disorders experienced improved essential fatty acid levels once their weight normalized. The study suggests that providing omega-3 supplements is not necessary if they adopt healthy eating behaviors and gain weight.
Research found that many top YouTube videos depict nurses in a derogatory way, with stereotypes including them as skilled professionals, sexual objects, or incompetent caregivers. The study highlights the need for professional bodies to lobby legislators to protect nursing from negative stereotyping and support positive promotion.
A new study found that screening intervals between one and three years have similar outcomes for gastric cancer stages, but longer intervals lead to more advanced cancer at diagnosis. The researchers recommend a screening interval of every three years in high-risk regions.
A new study published in Drug Testing and Analysis found that DMAA, a stimulant in many pre-workout supplements, does not originate from natural substances but is comprised of synthetic compounds. The FDA should regulate and/or ban products with significant amounts of synthetic pharmacological compounds added.
Research finds that tobacco use increases the risk of viral hepatitis reinfection after liver transplantation. Smokers may experience lower immune system response, making them more susceptible to complications.

A new study finds that rheumatoid arthritis (RA) patients receive regular cancer screenings, including breast, cervical, and colon cancer tests, at similar rates to the general population. The study's results challenge previous research suggesting RA patients receive fewer cancer screenings.
A new study suggests that government initiatives to strengthen low-income marriages should focus on addressing specific problems rather than promoting the institution of marriage. Low-income respondents reported similar romantic standards and experiences as high-income couples, despite facing unique economic and social issues.
A study found that liver stiffness measured by transient elastography is an independent predictor of liver failure, hepatocellular carcinoma, and mortality in cirrhotic patients coinfected with HIV/HCV. The measurement also predicts potential recovery and survival in patients with cirrhosis.
