Psychological therapies, particularly cognitive behavioural therapy, have been shown to be effective in treating post-traumatic stress disorder in children, reducing anxiety and depression symptoms.
Researchers suggest that the large size of sauropod dinosaurs may be attributed to a high C/N ratio in their plant-based diet. This theory proposes that young sauropods had a metabolism similar to modern mammals, while adults might have relied on humps of fat reserves instead of heat dissipation due to overheating.
The study reveals that baby boomers with hepatitis C are at risk of developing liver cancer, leading to a significant increase in liver transplant demand. As this population ages, the number of liver transplants for HCV-related liver disease is expected to rise.
The adult antiviral drug tenofovir disoproxil fumarate (tenofovir DF) has been found to be safe and effective in treating adolescents with hepatitis B virus (HBV), with a virologic response rate of 89% in pediatric participants. This study contributes to the growing body of evidence on the management of chronic HBV in children and teens.
Researchers have developed a simple breath analysis technique that can screen for colorectal cancer with an accuracy of over 75%. The method analyzes volatile organic compounds in exhaled breath, which are different in patients with cancer.

This study suggests that RA patients face increased complications compared to osteoarthritis (OA) patients.
Researchers found artificial light from industrial areas influences the foraging behavior of common redshanks, allowing them to forage more efficiently at night. This contradicts previous studies that reported negative effects of light pollution on wildlife.
Studies show that hummingbirds using more energy to feed from vertically oriented flowers, challenging previous hypotheses on flower evolution. Researchers suggest other factors dictate flower orientation, including excluding less efficient pollinators and nectar dilution.
A new Swedish study reveals that adolescents with lower peer status are at a higher risk of becoming regular or heavy smokers in adulthood. Researchers found that marginalized students, those nominated few times by their classmates, were more likely to adopt smoking as a behavior.
A commonly prescribed inpatient sleeping drug has been associated with a significant increase in falls among hospital patients. The study found that zolpidem use was linked to a fourfold higher fall rate compared to non-users.
A study published in Functional Ecology found that grasshoppers living beside noisy roads produce different songs with elevated frequency components. This adaptation helps them make themselves heard above road traffic, potentially disrupting the grasshopper's mating system.
A new systematic review found that people who received mobile phone-based smoking cessation services were more likely to stay away from cigarettes for six months. The review analyzed data from five studies involving over 9,000 participants, showing a nearly doubling of quit rates in intervention groups compared to control groups.
Aerobic exercise can help relieve fatigue associated with cancer and treatment, balancing rest with physical activity may reduce fatigue. The new review adds 28 studies, including those in breast cancer patients, showing that aerobic exercise benefits those with solid tumours during and after treatment.
A new study found that black patients with kidney cancer have a survival disadvantage compared to white patients, even when diagnosed at early stages or receiving less aggressive treatment. The study analyzed nearly 40,000 renal cell carcinoma patients and confirmed poorer survival rates for blacks.
A new study published in Hepatology found that African American women co-infected with HIV and HCV have lower liver-related mortality rates compared to Caucasian and Hispanic women. This finding suggests that racial disparities in liver disease may be influenced by other factors beyond just the presence of the virus.
Researchers found that living donor liver transplant recipients had better quality of life than the general Japanese population, except those with medical problems after donation. The study also discovered a significant correlation between decreased long-term HRQOL and age, persistence of symptoms, or additional diseases.
The article assesses Australia's giant eucalyptus trees' classification as rainforest species, sparked by their unique relationship with fire. The study finds that despite being dependent on fire for regeneration, these trees coexist on the margins of rainforests and should be considered part of the ecosystem.
Research finds women with systemic lupus erythematosus (SLE) have a two-fold increase in risk of preeclampsia. DMARD use during pregnancy may also pose a slight risk, with the severity of autoimmune disease contributing to the increased risk.
The American College of Rheumatology recommends using musculoskeletal ultrasound (MSUS) to diagnose and manage rheumatic diseases. MSUS can provide a faster, more accurate diagnosis, better measurement of treatment success, reduced procedural pain, and improved patient satisfaction.
A recent study published in the Journal of Clinical Nursing found that nearly a quarter of patients with rheumatoid arthritis and osteoarthritis used complementary and alternative therapy (CAT) to manage their condition. The majority reported improvements in pain intensity, sleeping patterns, and activity levels after using CAT.
Researchers found that ancient European hippos shrunk in size during the Pleistocene Era due to changing environmental conditions. The study suggests that temperature, food availability, and other factors influenced their adaptation.

A new study found that men with high blood pressure, high blood sugar, and a high body mass index are more likely to die from prostate cancer. Researchers also discovered that combining these metabolic factors increases the risk of death, suggesting that lifestyle changes may help prevent this.
The Otton frog uses a pseudo-thumb with sharp spikes to fight and mate, with males demonstrating larger thumbs and jabbing responses during combat. The discovery sheds light on the evolutionary origins of this unique trait.
Babies born to HIV-positive mothers are at risk of measles infection due to impaired maternal antibodies. Early immunization is crucial to prevent measles virus transmission and complications.

Researchers found that mother wolves' body weight and pack size play a crucial role in enabling pups to survive and thrive. The study suggests that managers can use information on pack size, female wolf weight, and disease prevalence to set harvest limits and ensure sufficient population growth.
Women who regularly use aspirin have a decreased risk of serous ovarian cancer, an aggressive form of the disease. However, the benefit must be balanced against potential adverse effects of pain medication use.
A comparative study of 80 patients found that coffee consumption reduced recovery time for bowel movements and tolerance of solid food after colon surgery. Coffee also helped patients pass stool sooner, with an average time of just over 60 hours.
A variant in the NFKB1 gene has been associated with a 44% reduced risk of lung cancer, according to a new analysis of 378 patients and 450 healthy controls. The study suggests that inflammation may play a role in lung cancer development.
