A study published in The Lancet found that same-day testing and treatment led to high rates of compliance with recommended treatment, with 83.2% returning for a follow-up visit. The 'one-stop' approach also improved patient satisfaction, with nearly 98% saying the treatment was equal to or better than expected.
A study of 4,500 youth ages 9, 13, and 16 found higher systolic blood pressures than expected, with more significant increases in obese children. The research suggests a strong correlation between childhood obesity and elevated blood pressure.
An anthropologist reveals that most suicide terrorists are educated and economically well-off individuals who feel despair and are manipulated by elites. To combat this, empower moderates within communities and strengthen interactions between different groups.
A study found that green and white tea can prevent colon tumors as effectively as the prescription drug sulindac. Moderate consumption of these teas may provide cancer protection without side effects associated with NSAIDs. The combination of tea and sulindac showed an 80% tumor reduction.
Researchers discovered that MHC proteins, including M10, play a crucial role in detecting and modulating pheromone activity in mice. The findings suggest that these proteins may act as escorts for pheromone receptors, allowing them to reach the surface of neurons where chemical reception takes place.
The Prostate Cancer Series assesses the epidemiology of prostate cancer, highlighting the impact of genetic and environmental risk factors. Despite progress in understanding diet-related risks, familial clustering, and ethnic variation remain poorly understood, presenting opportunities for further research.
Research suggests that employed African-American women have a 33% lower risk of coronary events compared to their homemaking counterparts. The study found no significant difference in heart disease rates among white women who worked outside the home and those who were homemakers.
A recent study by Penn researchers refutes prior research findings on the mental health impact of genetic testing for breast cancer. The study found that genetic testing is a tool for establishing truth and examining health strategies, rather than a source of anxiety.
Researchers have identified the matchmaker protein SYG-1, which guides nerve cells to form synapses during embryonic development. This discovery may lead to new treatments for disorders such as chronic epilepsy and chronic pain, where synapse formation goes awry.
A Wake Forest study found a high level of food insecurity among farm workers, especially those with children. The researchers recommend that agricultural employers, health and social service providers, and churches provide access to higher quality food for farm worker families to prevent future health problems.
A new study published in Critical Care found that 70% of transplant doctors would consider accepting organs from poisoned patients. This increase in organ donation could save lives and address the global shortage of healthy organs available for transplant operations.
The American Heart Association has released comprehensive guidelines for preventing atherosclerotic cardiovascular disease in children. The guidelines recommend health promotion goals, identifying risk factors in childhood and safely modifying them without harm to the growing child. For high-risk children, specific testing is recommend...
A new study finds that children in low-income families are not harmed when their mothers leave welfare and enter the workforce. The research also suggests that mothers' entry into the labor force is related to improvements in adolescents' mental health, while exits from employment are linked to increased behavior problems.
Researchers discovered a new gene mutation that affects L-DOPA production, potentially leading to new treatments for glaucoma. The study found that administering L-DOPA prevented severe abnormalities in mice with a genetic defect similar to primary congenital glaucoma.
A groundbreaking study by University of Melbourne researcher Dr. John Sader challenges the widespread use of V-shaped cantilevers in atomic force microscopy.
