A recent study by Robert J. Gatchel confirmed that patients scoring high on the Pain Medication Questionnaire (PMQ) test demonstrate higher levels of substance abuse, psychopathology, and physical/life functioning problems. The study found that patients in the high-PMQ group are 3.2 times more likely to request early medication refills.
A critical review found that repeated administration of antiepileptic drug therapy leads to diminishing results in preventing seizures. Acquired tolerance is responsible for this effect, with some patients developing cross-tolerance to similar medication, posing a significant concern for medically intractable epilepsy
As permafrost melts in North Siberia, carbon sequestered for 40,000 years is released as methane, exacerbating global warming. Methane emissions from thaw lakes have increased estimates by 10-63%, highlighting the critical role of Northern wetlands in atmospheric methane release.
Researchers found that a gene for an anti-insect enzyme is up to 250 times more active in people with severe sinus inflammation. The enzyme's presence was linked to chronic sinusitis, which affects an estimated 32 million Americans.
Researchers have identified an enzyme called puromycin-sensitive aminopeptidase (PSA) that snips apart abnormal protein tangles in the brain, potentially providing a protective mechanism against neurodegeneration. Higher levels of PSA gene expression were found in cerebellum regions resistant to neurodegeneration.
A recent study finds that media coverage is becoming more gender-balanced, with women candidates receiving more attention and paragraphs published about them. The study suggests that this shift may be advantageous to female politicians, leading to an environment more favorable to their advancement.
The partnership aims to support the training of young investigators in pediatric gastroenterology, hepatology, and nutrition. Hepatology will now be made available without charge to NASPGHAN fellows.
The study reveals that 1- and 3-year-old children, as well as great apes, prefer a place-based strategy to remember hidden items, while humans reassess this preference with age. This suggests that some evolved cognitive strategies are masked early on in human development.
Researchers analyzed branching morphogenesis in lung, kidney and mammary glands, shedding light on organ development and implications for human health. The study's findings have significant implications for genetic manipulation and virtual reconstruction of organogenesis.
The American Political Science Association (APSA) announced its 2006 award recipients, recognizing outstanding scholarly achievements in various fields. The awards included book and dissertation prizes, as well as career honors for notable public service and journalistic contributions.
New research suggests that international fishing trade can benefit developing African countries by generating foreign exchange revenue and improving local food security. The trade in high-value fish species, such as tuna and squid, helps underpin domestic fisheries and supports the livelihoods of thousands of people.
A new H5N1 influenza vaccine has produced a safe and effective immune response in healthy people at low doses, with the highest dose showing the best response. The vaccine was well-tolerated and did not have significantly more side effects compared to a placebo.
A new study found that state health department websites are often written at a level too difficult for the average American, with only 20% of sites at an eighth-grade reading level in 2005. Many websites also lack accessibility features for people with disabilities and non-English speakers, making it hard for them to access essential i...
Sven-Eric Jordt and Michelle L. Bell received the Outstanding New Environmental Scientist (ONES) Award for their research on environmental health, focusing on asthma, allergy, and dermatitis. Their studies will investigate the relationship between environmental exposures and human disease.
A study published in the American Journal of Epidemiology found no increased risk of pregnancy loss related to drinking water disinfection by-products. The research, led by David A. Savitz, Ph.D., used data from 2,409 women and 258 pregnancy losses, concluding that tap water DBPs do not pose a measurable risk to fetal health.
The CSIRO has signed a three-way coal research and development Joint Statement with Japan Coal Energy Centre (JCOAL) and Australian Coal Research Ltd (ACARP). The agreement aims to improve coal production technology, mine safety and coal utilization. This collaboration will enhance the capabilities of both countries in these areas.
A study published by Infectious Diseases Society of America found that antibiotic-resistant bacteria are causing an increase in muscle infections, particularly among children. The researchers discovered a specific strain of Staphylococcus aureus associated with more severe disease, and emphasized the need for physicians to consider ini...
Researchers at the University of Cincinnati are studying whether environmental toxicants can worsen lung disease by activating a receptor that causes the immune system to attack stressed lung tissue. Chronic exposure to toxins like tobacco smoke and air pollutants may exacerbate damage, leading to additional health problems.
A recent study found that 30% of nurses reported both verbal and physical abuse in the last four working weeks. The most common forms of physical abuse were strikes from hands or fists, while verbal abuse was mostly rudeness and shouting. The research highlights a disturbing trend of workplace aggression in modern healthcare settings.
Mark Brandon's award-winning research explores the dynamics of erosion in tectonically active mountain ranges. His work has shed light on the interplay between accretion, erosion, and wedge growth in shaping the Earth's surface.
