The study of 300 patients with chronic myeloid leukemia showed that even single mismatches in key genes don't affect long-term survival.
Marion Nestle reviews the history of olestra's approval, highlighting the FDA's decision to approve the fat substitute while requiring warning labels. She calls for changes in the regulatory system to move towards alliances with industries, increasing FDA research authority and funding.
A two-year study found that environmental stressors, such as unemployment and lack of health insurance, contribute to high blood pressure in young African-American males. An intervention team's efforts led to a 50% blood pressure control rate and a 75% decrease in emergency room visits.
The article discusses various public health issues, including tobacco control, food industry manipulation, and violence prevention. It highlights the importance of vaccination coverage estimation using parental recall, medical records, and other methods to prevent diseases such as tuberculosis.
Eleven German research centers are extending their funding by two years, totaling over DM 30 million, to develop innovative biomolecular recognition systems, biomedicine applications, and industrial solutions. This initiative supports the technology transfer from universities to regional companies.
Researchers found that combining abciximab with two low-dose boluses of reteplase provided complete blood flow to up to 35% more patients than using abciximab alone or in combination with a single dose of reteplase. This new strategy may represent an exciting new step in treating most heart attacks.
The ASU geology team is collecting and analyzing data from the Galileo spacecraft, which shows strong evidence of a liquid ocean under Europa's surface. The images transmitted by the spacecraft reveal terrain types similar to an iceberg found on Earth near Europa's surface.
Researchers found that injecting methotrexate significantly improved patient health and reduced costs for those with juvenile rheumatoid arthritis or rheumatoid arthritis. The study involved 52 patients, with 73% switching to injection treatment due to dissatisfaction with oral method side effects.
A recent study found that high levels of inflammation can impede the effectiveness of clot-busting treatment after a heart attack. Individuals with elevated C-reactive protein levels had slower responses to thrombolytic therapy, resulting in delayed revascularization and increased damage to the heart.
A University of North Carolina at Chapel Hill study suggests that consuming vitamin E and other antioxidants may help reduce the risk of knee arthritis. Middle-aged and older individuals who follow a diet rich in these compounds, such as green vegetables and tomatoes, may experience a 30% lower risk of developing osteoarthritis.
According to the study, American children now spend less than an hour per week reading and almost no time engaging in unstructured outdoor play. Meanwhile, TV viewing has become a significant part of their daily routine, with nearly a quarter of their free time spent watching television.
A 12-year study of doctors found that men who ate a diet rich in nuts had a decreased risk of dying from heart disease. In another study, people eating an oat-rich diet had lower blood pressure and reduced cholesterol levels.
The FDA analyzed 94,120 adverse event reports on silicone gel breast implants from 1984-1995. Reports increased significantly after media coverage in 1991-1992, with a shift towards more complex and varied symptom reports.
A study at Duke University Medical Center found Hispanic heart patients experienced a median delay of nine minutes from symptom onset until receiving medical therapy. Despite differences in treatment, clinical outcomes were similar between Hispanic and non-Hispanic patients.
Researchers found that liver ischemia/reperfusion injury induces a caspase-dependent apoptosis in endothelial cells. The study identified the type of affected cell and the molecular pathway responsible for the damage, opening doors to develop therapies to prevent or reduce liver preservation injury.
The REACT trial found a median delay of 2.2 hours, far lower than most U.S. studies have found, indicating an improvement in patients seeking care earlier. This decline is attributed to increased awareness and education about heart attack symptoms and the need for rapid action.
A new study by Merrill F. Elias and colleagues found that individuals with one or more risk factors for heart disease, such as diabetes, obesity, and smoking, are more likely to experience cognitive decline, including memory and learning impairments.
A recent study published in the American Heart Association meeting reveals that hypertension is a significant risk factor for heart failure among urban African Americans. The study analyzed data from cardiac catheterization patients and found a higher prevalence of heart failure among African Americans compared to Caucasians.
The tobacco control community was divided over the merits of providing legal protections to the tobacco industry, wasting time and credibility. Despite this, state and local tobacco control efforts are gaining momentum, with promise in class action litigation against tobacco manufacturers.
A study by Case Western Reserve University professor Miriam Grushka found that low doses of clonazepam can provide significant relief from burning mouth syndrome, a chronic condition affecting 1.3 million adults. The medication may prevent spontaneous firing of the cranial nerve carrying pain sensations to the brain.
A study suggests that adding 4 cents to ticket prices in professional sports venues could cover the cost of automated external defibrillators and training staff, potentially saving thousands of lives. The estimated annual attendance at major league football, basketball, baseball, and hockey games is over 120 million.
A study by Johns Hopkins Medicine found that cases of life-threatening heart muscle inflammation are declining in the US, corresponding with a decline in enteroviral infections. Since 1991, myocarditis was present in less than 5% of patients biopsied each year, correlating with reduced enterovirus cases reported by the CDC.
The US Department of Energy's Brookhaven National Laboratory is offering a new clinical trial for brain tumor patients, including those whose cancer is inoperable or has regrown. The trial aims to increase the radiation dose and expand eligibility requirements for glioblastoma multiforme patients.
A case study published in JAMA reports a patient experiencing severe withdrawal symptoms after stopping valerian supplements. The researchers emphasize the importance of asking patients about herbal product use and providing open-minded care to address potential side effects and interactions.
