A University of Florida study found that many calcium supplements contain lead, posing a risk to consumers who ingest high doses. The researchers recommend choosing lead-free brands and labeling products to minimize exposure.
A study found that breast cancer mortality was almost identical in two groups of women aged 50-59, one receiving annual mammograms and the other physical examinations alone. Effective and regular breast physical examinations with breast self-examination may be an alternative to annual mammograms for this age group.
A study evaluated dosage adjustments of Agenerase in HIV patients taking efavirenz or nevirapine, showing that therapeutic plasma concentrations were maintained at 6 or 12 weeks. Dosage adjustments resulted in improved amprenavir levels in all cases, despite the presence of efavirenz or nevirapine.
A study found that the number of family members caring for chronically disabled parents or spouses decreased, but those who did were more likely to be primary caregivers. The Baby Boomer generation's lower fertility rate is expected to increase pressure on family care in the coming decades.
The phase III clinical trial demonstrated a significant reduction in S. aureus bacteremias during the first ten months, but not after one-year follow-up. The study found that StaphVAX-induced antibodies protected against bloodstream infections.
A study published in the Canadian Medical Association Journal examines the effects of global warming on world health, highlighting direct and indirect impacts. The authors conclude that reducing fossil fuel combustion and advocating for environmental improvements are essential to mitigate these risks.
Research in Occupational and Environmental Medicine shows that prolonged wakefulness impairs reaction times, accuracy, coordination, and attention span, similar to levels of alcohol intoxication. The effects are thought to be cumulative and pose a serious risk to safety, particularly in transportation settings.
A review by Sanjiv Agarwal and Akkinappally Venketeshwer Rao suggests that dietary antioxidants, particularly lycopene found in tomatoes, may have protective effects against cancer. Further research is necessary to establish guidelines for healthy eating and confirm the role of lycopene in disease prevention.
A major international trial found that giving extra radiotherapy to patients with early breast cancer substantially reduces the risk of cancer recurring in the breast. The study, involving 5,569 patients from nine countries, showed a significant benefit in younger women, particularly those under 40.
A new study from the University of North Carolina at Chapel Hill suggests that current PSA screening strategies should be changed. Testing men at ages 40 and 45, and then every two years after age 50, may prevent more deaths than waiting until age 50.
A study analyzing data from 28 countries found that a diet rich in olive oil was associated with a decreased risk of bowel cancer. The researchers discovered that meat and fish consumption, particularly high amounts, increased the risk of the disease, whereas cereal and vegetable intake had a protective effect.
Defibrillator availability for home use could save thousands of lives, says Dr. Mickey Eisenberg. Despite high costs, he suggests AEDs could become more affordable and accessible with proper labeling and training.
Research in Occupational and Environmental Medicine found that bullying at work increases sick leave among hospital staff, with victims and colleagues of bullies taking more time off. The study analyzed data from over 7000 employees across Finland, finding a significant link between workplace bullying and increased rates of sickness.
The State Children's Health Insurance Program (SCHIP) needs a broader scope and clearer goals to truly benefit children and families. States should focus on quality of care, including regular physician visits and preventive services, as well as plan ahead for primary care services and evaluate program effectiveness.
Researchers at MIT found that urban air pollution will not have a big effect on global temperature change, with some regional effects possible. The study used a new method to couple urban air chemistry models with global climate models, allowing for more accurate predictions.
A nurse home visitation program found to be less effective in preventing child abuse and neglect in households with high incidents of domestic violence. The study suggests that the program may not address the root cause of domestic violence, which can exacerbate child maltreatment.
Researchers at the University of Washington School of Dentistry found no link between periodontal disease and chronic coronary heart disease. Despite shared risk factors, their analysis of over 8,000 people showed only a slight connection.
A study of 9,454 patients found that abnormal heart rate recovery after exercise is a strong predictor of mortality. The researchers also discovered that the combination of abnormal heart rate recovery and a high-risk treadmill test score provides even stronger prognostic information.
Researchers found that zebra mussels stimulate bacterial production and increase numbers in sediment, but have a minor impact on the microbenthic community. The study suggests that zebra mussels may not disrupt normal processes of the microbenthic community.
