The United States Preventive Services Task Force (USPSTF) found insufficient evidence to recommend for or against routine screening for primary hypertension in asymptomatic children and adolescents. Hypertension in children and adolescents has increased over the past several decades, which may be attributable to the climb in childhood overweight and obesity rates. An estimated 11 percent of obese children in the United States suffer from hypertension, putting them at increased risk for hypertension in adulthood. One rationale for screening young patients is that it could ...

Maternal psychological distress combined with exposure to air pollution during pregnancy have an adverse impact on the child's behavioral development, according to researchers at the Columbia Center for Children's Environmental Health at the Mailman School of Public Health. The study, which appears in the journal Pediatrics, reports that maternal demoralization, a measure of psychological distress capable of affecting a mother's ability to cope with stressful situations, was linked with a number of behavioral problems, including anxiety, depression, attention problems, ...

Ideologues on both ends of the political spectrum are equally likely to believe their opinions are superior to others', but their feelings of superiority emerge for distinct political issues, according to new research published in Psychological Science, a journal of the Association for Psychological Science. These findings suggest that, while people with moderate attitudes tend to be more evenhanded, those on the extreme ends of the political spectrum seem especially convinced that their viewpoints are the only "correct" ones. Psychology researcher Kaitlin Toner, a postdoctoral ...

Obesity increases a chronic kidney disease patient's risk of developing kidney failure. Obesity suppresses an important cellular process that prevents kidney cell damage, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). The findings suggest that restoring the process could protect the kidney health of obese individuals. Obesity increases a chronic kidney disease patient's risk of developing kidney failure, but the mechanism underlying this connection has remained unclear. Kosuke Yamahara, Takashi Uzu, ...

DETROIT – A skin infection linked to exposure to contaminated water in home aquariums is frequently under-diagnosed, according to a Henry Ford Hospital study. Researchers say diagnosing and managing Mycobacterium marinum infection is difficult because skin lesions don't appear for two to four weeks after incubation, leading to delayed treatment and unnecessary and ineffective use of antifungal and antibacterial agents. During the incubation period, patients also fail to remember the source of the exposure, which is often traced to them cleaning their aquarium. Infection ...

CINCINNATI—University of Cincinnati (UC) researchers have discovered a biomarker, known as phosphatidylserine (PS), for pancreatic cancer that could be effectively targeted, creating a potential therapy for a condition that has a small survival rate. These findings, being published in the Oct. 4, 2013, online edition of PLOS ONE, also show that the use of a biotherapy consisting of a lysosomal protein, known as saposin C (SapC), and a phospholipid, known as dioleoylphosphatidylserine (DOPS), can be combined into tiny cavities, or nanovesicles, to target and kill pancreatic ...

SAN FRANCISCO – Oct. 4, 2013 – Healthcare workers' use of disposable gowns and gloves upon entering all patient rooms on an intensive care unit (ICU), versus only in rooms on standard isolation protocol, helped reduce patient acquisition of methicillin-resistant Staphylococcus aureus (MRSA) by approximately 40 percent, according to new research co-led by the University of Maryland School of Medicine and the Yale New Haven Health System Center for Healthcare Solutions. While the study did not show statistically significant results for preventing patient acquisition of another ...

The wearing of gloves and gowns by health care workers for all intensive care unit (ICU) patient contact did not reduce the rate of acquisition of a combination of the bacteria methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE), although there was a lower risk of MRSA acquisition alone, according to a study published online by JAMA. The study is being released early to coincide with its presentation at IDWeek 2013. Antibiotic-resistance is associated with considerable illness, death, and costs. MRSA and VRE are primary causes ...

INDIANAPOLIS -- An Indiana University cancer researcher and his colleagues have discovered new therapeutic targets and drugs that may someday benefit people with certain types of leukemia or blood cancer. Reuben Kapur, Ph.D., the Frieda and Albrecht Kipp Professor of Pediatrics at the IU School of Medicine and a researcher at the Indiana University Melvin and Bren Simon Cancer Center, and colleagues discovered in pre-clinical and pharmacological models that cancer cells with a mutation in the KIT receptor -- an oncogenic/cancerous form of the receptor -- in mast cell ...

HOUSTON – Children of melanoma survivors were more likely to wear hats and re-apply sunscreen after receiving a multi-media informational program designed specifically for them. These new findings were included in research published in the journal of Cancer Epidemiology, Biomarkers and Prevention – a publication of the American Association for Cancer Research. A team of researchers led by Ellen R.

WASHINGTON, D.C. Oct. 4, 2013 -- Researchers in Japan have developed a new photodiode that can detect in just milliseconds a certain type of high-energy ultraviolet light, called UVC, which is powerful enough to break the bonds of DNA and harm living creatures. The researchers describe their new device in the journal Applied Physics Letters. Although this radiation doesn't normally reach the Earth's surface, it can leak through to just below the hole in the ozone layer. Monitoring this radiation is a way of tracking the hole in the ozone layer, and photodiodes that measure ...

University of Notre Dame researchers Shahriar Mobashery and Mayland Chang and their collaborators in Spain have published research results this week that show how methicillin-resistant Staphylococcus aureus (MRSA) regulates the critical crosslinking of its cell wall in the face of beta-lactam antibiotics. The work, published in the Proceedings of the National Academy of Sciences, reveals the mechanistic basis for how the MRSA bacterium became such a difficult pathogen over the previous 50 years, in which time it spread rapidly across the world. Modern strains of MRSA ...

Understanding how genes act in specific tissues is critical to our ability to combat many human diseases, from heart disease to kidney failure to cancer. Yet isolating individual cell types for study is impossible for most human tissues. A new method developed by researchers at Princeton University and the University of Michigan called "in silico nano-dissection" uses computers rather than scalpels to separate and identify genes from specific cell types, enabling the systematic study of genes involved in diseases. The team used the new method to successfully identify ...

Philadelphia, Pa. (October 4, 2013) – Doctors who abuse prescription drugs often do so for "self-medication"—whether for physical or emotional pain or stress relief, reports a study in the October Journal of Addiction Medicine, the official journal of the American Society of Addiction Medicine. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. Based on focus groups with physicians in treatment for substance abuse, the findings lend "unique insights" into the reasons why doctors abuse prescription medications—as well as important ...

SAN FRANCISCO – Swallowing pills containing a concentrate of fecal bacteria successfully stops recurrent bouts of debilitating Clostridium difficile (C. diff) infection by rebalancing the bacteria in the gut, suggests a study being presented at the IDWeek 2013™ meeting today. Infection from C. diff bacteria is such a concern that the Centers for Disease Control and Prevention (CDC) named it one of the three most urgent threats in its recent landmark report on antibiotic resistance. C. diff sickens half a million Americans and kills 14,000 every year. C. diff infection ...

SAN FRANCISCO – A vast majority of people who see their doctors for sore throats or acute bronchitis receive antibiotics, yet only a small percentage should, according to analyses of two major national surveys being presented at IDWeek 2013™. Those illnesses usually are caused by viruses, and antibiotics – which only treat bacterial infections – do not help. Harvard University researchers analyzed the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey and determined that doctors prescribed antibiotics in 60 percent of visits ...

SAN FRANCISCO – When patients with HIV are hospitalized for other conditions, such as a heart problem, surgery or complications of diabetes, mistakes are often made involving their complicated anti-retroviral therapy (ART) regimens. But those errors are more than twice as likely to be corrected when patients are seen by an infectious diseases (ID) physician, suggests a Cleveland Clinic study being presented at IDWeek 2013™ today. Most patients with HIV are cared for by physicians with HIV expertise in the community, and when they are hospitalized for non-HIV conditions, ...

Portland, Ore., USA (October 4, 2013) --- Being overweight shortens a dog's life expectancy according to new research by the WALTHAM® Centre for Pet Nutrition. Data on a range of popular dog breeds from across the USA showed that dogs that are overweight in middle age have a shorter life expectancy than ideal weight dogs. Specifically, overweight dogs were found to suffer a reduction in life expectancy of up to ten months compared to ideal weight dogs. Being overweight in middle age can have potentially far-reaching consequences for a dog's life span, highlighting the importance ...

SAN FRANCISCO – An investigational vaccine appears generally well tolerated and effective against the most common strain of norovirus, reducing the main symptoms of the gastrointestinal (GI) infection, vomiting and/or diarrhea, by 52 percent, suggests research being presented at IDWeek 2013™. Currently, there is no treatment or cure for norovirus, the most common cause of severe GI infection in the United States. Norovirus is highly contagious. Significant outbreaks occur in health care facilities, childcare centers and other places where people are in close quarters, ...

SAN FRANCISCO – Although they are at higher risk for cervical cancer, girls from low-income families are less likely to receive the human papillomavirus (HPV) vaccine that prevents it, and the reasons they are not fully vaccinated differ depending on whether their parents are English-speaking or Spanish-speaking, suggests research being presented at IDWeek 2013™. In the study, Spanish-speaking parents whose daughters were not fully vaccinated said their providers either did not encourage the vaccine or didn't explain that three shots were necessary for full protection. ...
