Researchers Identify 'Smoking Gun' - Grandmother's Smoking Could Be The Cause Of Grandchild's Asthma
Date: Mar-05-2013Grandmother's cigarette smoking could be responsible for her grandchild's asthma, and the recent discovery of this multi-generational transmission of disease suggests the environmental factors experienced today could determine the health of family members for generations to come, two Los Angeles Biomedical Research Institute (LA BioMed) lead researchers write in the March edition of Review of Obstetrics & Gynecology. The researchers, John S. Torday, PhD, and Virender K. Rehan, MD, wrote an editorial citing recent studies by Dr...
Concerns Raised That The 'Shelf Life' Of Blood May Be Shorter Than We Think
Date: Mar-05-2013A small study from Johns Hopkins adds to the growing body of evidence that red blood cells stored longer than three weeks begin to lose the capacity to deliver oxygen-rich cells where they may be most needed. In a report published online in the journal Anesthesia & Analgesia, the Johns Hopkins investigators say red cells in blood stored that long gradually lose the flexibility required to squeeze through the body's smallest capillaries to deliver oxygen to tissue. Moreover, they say, that capacity is not regained after transfusion into patients during or after surgery...
Molecular Mechanism Identified For Response To Cardiac Stress
Date: Mar-05-2013Myocardial hypertrophy, a thickening of the heart muscle, is an adaptation that occurs with increased stress on the heart, such as high blood pressure. As the heart muscle expands, it also requires greater blood flow to maintain access to oxygen and nutrients, necessitating an expansion of the cardiac vasculature. In this issue of the Journal of Clinical Investigation, Daniela Tirziu and researchers at Yale University identified a molecular mechanism by which the growth of new blood vessels (angiogenesis) and heart muscle growth are coordinated...
Key Role In The Development Of Schizophrenia Played By Malign Environmental Combination
Date: Mar-05-2013The interplay between an infection during pregnancy and stress in puberty plays a key role in the development of schizophrenia, as behaviourists from ETH Zurich demonstrate in a mouse model. However, there is no need to panic. Around one per cent of the population suffers from schizophrenia, a serious mental disorder that usually does not develop until adulthood and is incurable. Psychiatrists and neuroscientsist have long suspected that adverse enviromental factors may play an important role in the development of schizophrenia...
Over 360 Million People With Hearing Loss Worldwide
Date: Mar-05-2013The World Health Organization estimates that there are over 360 million people in the world living with disabling hearing loss. As people are living longer than they did in the past, the prevalence of hearing loss has also gone up. Close to a third of people above the age of 65 live with hearing loss. Even though there are devices that can restore a person's ability to hear, they are commonly in short supply...
Disappointing Results From African HIV Study
Date: Mar-05-2013Attempting to prevent HIV infection via vaginal gels or daily medicine has proven to be ineffective in the southern African region that is devastated by a high number of cases of the disease, because people did not use the medicine as required. The finding came from a large-scale HIV prevention trial among African women known as VOICE (Vaginal and Oral Intervention to Control the Epidemic) and has provided an urgent reminder that products must meet the needs of those people using them...
Obesity Gene Linked To Skin Cancer
Date: Mar-05-2013A gene associated with obesity and overeating is also linked to the most fatal skin cancer, malignant melanoma. The finding came from a new study conducted by Cancer Research UK experts at the University of Leeds, England, and was published in Nature Genetics. Individuals with certain variations in a stretch of DNA within the FTO gene, known as intron 8, may have a higher chance of developing melanoma, according to the results...
IT For Operation, Care, And Translation
Date: Mar-05-2013Computers Recognize User Emotion and Intention People communicate on more levels than just by language: Mimics, gestures, and view directions also play an important role. Depending on the sex, age, and person, however, interpretation of the words spoken may vary. Computers perceiving these parameters will have a number of potential applications in the future...
Patient Satisfaction Starts At The Bedside
Date: Mar-05-2013Quality is a central component of any discussion around health care and one of the key dimensions and measurements of quality care is the patient experience. However, many healthcare organizations struggle to become 'patient focused' and fail to score well on patient satisfaction surveys. New research from Brigham and Women's Hospital, published in the March edition of British Medical Journal Quality and Safety, offers a potential explanation -- insufficient support from hospital management to improve the patient experience by engaging physicians and nurses in the process...
Optimism And Feelings Of Vulnerability Skewed Following Tornado, Should Be Reflected In Emergency Preparedness
Date: Mar-05-2013Even in the face of a disaster, we remain optimistic about our chances of injury compared to others, according to a new study. Residents of a town struck by a tornado thought their risk of injury from a future tornado was lower than that of peers, both a month and a year after the destructive twister. Such optimism could undermine efforts toward emergency preparedness. After an F-2 tornado struck his town in Iowa, Jerry Suls, a psychologist at the University of Iowa who studies social comparison, turned his attention to risk perception...
