Early identification of trauma risk in small children after an accident
Date: Sep-25-2013Accidents also traumatize small children. Around one in ten children still suffers from a post-traumatic stress disorder a year after a road accident or burn injury, reliving aspects of the traumatic experience in the form of flashbacks or nightmares. In doing so, young children keep replaying the stressful memories while avoiding anything that might remind them of the accident in any way. As a result of this constant alertness to threatening memories, the children can develop sleeping disorders, concentration problems or aggressive behavior...
Microbiologists describe how 'natural killer' cells depend on enzyme to develop
Date: Sep-25-2013Natural killer (NK) cells in the human body can kill and contain viruses and cancerous tumors, and a new study from the University of Southern California (USC) describes for the first time how those cells can be manipulated by epigenetics. The discovery, detailed in the Proceedings of the National Academy of Sciences, paves the way for developing more effective cancer drugs. "Natural killer cells are very attractive targets for immunotherapy because they are able to kill tumor cells," said Si-Yi Chen, M.D., Ph.D...
New study suggests that you can never really completely leave addiction behind
Date: Sep-25-2013It is often said that once people develop an addiction, they can never completely eliminate their attraction to the abused substance. New findings provide further support for this notion by suggesting that even long-term abstinence from cocaine does not result in a complete normalization of brain circuitry. Scientists are currently trying to answer some of the 'chicken and egg' questions surrounding the abuse of drugs...
Simple screening for depression in cancer patients
Date: Sep-25-2013Cancer patients can be accurately screened for major depression with a simple two-question survey, according to a study presented at the American Society for Radiation Oncology's 55th Annual Meeting. The two-question screening test proved to be as accurate as a longer nine-question screening test. The study was presented at plenary session by William Small, Jr., MD, FASTRO, chair of the Department of Radiation Oncology of Loyola University Medical Center. "We found that a two-question survey can effectively screen for depression," Small said...
First-time mothers often experience problems with breastfeeding
Date: Sep-25-2013Most new mothers in the United States begin breastfeeding when their children are born, but new research shows that those who report early concerns or problems with breastfeeding are nearly 10 times more likely to abandon breastfeeding within two months. In a new study 92 percent of new moms reported at least one breastfeeding concern three days after birth. The most predominant concern, in 52 percent of mothers, was infant feeding at the breast, which refers to the behavior of the baby, such as not "latching on" properly...
Link between partner violence and specific drinking environments
Date: Sep-25-2013Researchers have long known that violence toward spouses and partners increases with the frequency and volume of drinking. A study published in the scientific journal Addiction shows that the context in which drinking occurs also appears to play a role in violence against partners, with male violence being linked to drinking away from home and female violence being linked to drinking at home...
Preventing malaria in travelers to West Africa reduces health costs
Date: Sep-25-2013Not only do U.S. travelers to West Africa who consult health providers before they leave and take prescribed preventive medications substantially reduce their risk of contracting malaria, they also reduce costs to their health insurance providers and, in most cases, to themselves. In a report that has been published online in Clinical Infectious Disease, researchers from the U.S...
Memory development continues deep into childhood
Date: Sep-25-2013Young Children Have Difficulty when Elements of Memory Overlap A new study provides evidence that one important part of memory undergoes substantial development even after the age of 7. Researchers found that episodic memory - the ability to remember not only what happened, but where and when - takes longer to develop than often assumed. That means young children may have no problem with remembering certain simple events or facts. But in some cases, they may have difficulty placing them in the right place, time or context...
What is heat stroke or sunstroke?
Date: Sep-24-2013Heat stroke, also known as sunstroke, is a serious medical condition, a medical emergency, when the body's temperature rises too high as a result of excessive heat exposure. The body loses its ability to cool itself and overheats. When a person's body temperature is greater than 40.6°C (105.1°F), and this is caused by environmental heat exposure with poor thermoregulation (temperature control), they have heat stroke. Heat stroke is not a fever, where the body deliberately raises its temperature in response to, for example an infection...
H1N1 flu: pregnant women can safely take vaccine
Date: Sep-24-2013The question of whether or not to vaccinate against the flu is just one of many decisions pregnant women must make. However, a new large national study may put some fears to rest after revealing evidence that the H1N1 vaccine is safe during pregnancy. A collaboration between researchers from the University of California-San Diego (UCSD), Boston University, and the American Academy of Allergy Asthma and Immunology (AAAAI) yielded one large national study and two companion papers published in the journal Vaccine...
