Ozone Health Guidelines
Like the weather, ozone concentrations change from day to day and even hour to hour. The highest concentrations commonly occur in the afternoon and early-evening hours on hot, sunny days. Ozone affects everyone, but some people are more sensitive to its impacts than others. People with existing respiratory problems such as asthma, bronchitis and emphysema are more likely to be affected. Even healthy people may feel the impacts of ozone when they are outdoors working, playing or exercising and breathing ozone more deeply into their lungs. Children are particularly vulnerable because they spend time outdoors playing vigorously, their lungs are still developing, and pound for pound, they breathe in more air than do adults. The health effects linked to increased ozone concentrations vary among individuals but may include: coughing; nose, and throat irritation; chest pain; aggravation of asthma; shortness of breath; increased. susceptibility to respiratory infection; decreased lung function; and other respiratory ailments. The Department of Environmental Protection provides air quality ratings for ozone each day from May through September using the color categories and Air Quality Index numbers shown below. A higher Air Quality Index number within the categories reflects a higher level of risk......... Posted by: Tyler Permalink Source High Humidity Is A Risk Factor For Heart Attack
The researchers analysed all reported deaths in Athens for the whole of 2001 and looked at daily weather reports from the National Meteorological Society on temperature, pressure levels, and humidity for the same year. The total number of heart attack deaths during the year numbered 3126, of which 1953 were in men. There were sharp seasonal variations in the timing of the deaths, with the overall proportion of deaths a third higher in winter than in summer. Deaths among those aged 70 and above accounted almost entirely for this variation. In this age group deaths from heart attack were 3.5 times higher in June and seven times higher in December than rates in other age groups. The lowest recorded temperature on three days in December reached 1 degree Celsius (34 degrees Fahrenheit), with an average of 6 degrees Celsius, and the highest, on two days in August reached 39 degrees Celsius (102 degrees Fahrenheit), with an average of 34 degrees Celsius. The average daily temperature for the preceding week was the most significant factor influencing the daily death rate......... Posted by: Sean Permalink Source Targeting Mesothelioma
National Cancer Institute is sponsoring the current clinical trial with CuraGen. Those who are having a diagnosis of mesothelioma, which is not removable by surgery and who have failed at least one line of chemotherapy are eligible for the clinical trial. The drug PXD101 is given by intravenous infusion once every three weeks. The scientists are trying to determine if the drug PXD101 has any significant activity on mesothelioma in terms of clinical response. The study is also aimed at determining the safety of the drug and time to therapy failure. The study would also look for any survival advantage resulting from the use of the drug. Scientists are planning to enroll a total of 37 patients at different sites across the United States. Histone deacetylase inhibitors have the ability to down-regulate genes such as BCL-XL and VEGF and up-regulate cell-cycle regulating genes, including p21. Scientists say that they are excited to begin the trial and would evaluate PXD101 as a potential therapy for mesothelioma......... Posted by: Sean Permalink Late Talking Toddler Debunking The Myth
The LOOKING at Language project has analysed the speech development of 1766 children in Western Australia from infancy to seven years of age, with particular focus on environmental, neuro-developmental and genetic risk factors. It is the first study to look at predictors of late language. LOOKING at Language Chief Investigator Professor Mabel Rice said the research found that 13 per cent of children at two years of age were late talkers. Boys were three times more likely to have delayed speech development, while a child with siblings was at double the risk, as were children with a family history of late talkers. The study found that a mother's education, income, parenting style or mental health had no impact on a child's likelihood of being a late talker. Study Coordinator Associate Professor Kate Taylor said the findings debunked common myths about why children are late talkers. "Some people have wrongly believed that delayed language development could be due to a child not being spoken to enough or because of some other inadequacy in the family environment," Associate Professor Taylor said.........

With such a large percentage of the population weighing more than is healthy, the public-health implications of being overweight have taken on greater importance. The burgeoning percentage of heavy Americans has economic consequences, too. Scientists at the U.S. Centers for Disease Control and RTI International estimated that 2003 health-care costs attributable to obesity reached $75 billion, with taxpayers picking up about half of the bill through programs like Medicare and Medicaid......... Posted by: Sean Permalink Source Middle Back Seat Is The Safest In A Car
It also happens to be the safest. University at Buffalo scientists studied all auto crashes involving a fatality in the U.S. between 2000 and 2003 where someone occupied the rear middle-seat. They found that occupants of the back seat are 59 percent to 86 percent safer than passengers in the front seat and that, in the back seat, the person in the middle is 25 percent safer than other back-seat passengers. "After controlling for factors such as restraint use, vehicle type, vehicle weight, occupant age, weather and light conditions, air-bag deployment, drug results and fatalities per crash, the rear middle seat is still 16 percent safer than any other seat in the vehicle," said Dietrich Jehle, M.D., UB associate professor of emergency medicine and lead author on the study. Results of the study were presented at the May meeting of the Society for Academic Emergency Medicine in San Francisco, Calif. Jehle and his colleagues at the Center for Transportation Injury Research (CenTIR), conducted a retrospective cohort study of fatal crashes in which there were rear-seat occupants and at least one fatality in the vehicle. CenTIR is headquartered in the Erie County Medical Center and is affiliated with the Calspan UB Research Center (CUBRC)......... Posted by: Jim Permalink Source Reducing Heart Implant Patients' Anxiety
Just ask Ed Burns, of Ocala, who received an implantable cardioverter defibrillator, or ICD, five years ago. The uncertainty of when or if the device would fire made him wary of driving long distances. Before setting out on a road trip to California to visit family, Burns researched and made a list of every medical center along the route that could treat ICD patients. Now a new tool from the University of Florida can help health-care providers identify which patients may need psychological services to cope with anxiety. It's called the Florida Shock Anxiety Scale, and UF scientists report on its effectiveness in the current issue of Pacing and Clinical Electrophysiology. The research was done as part of a continuing series of investigations on ICD recipients' psychological health led by Samuel Sears, Ph.D., an associate professor in the department of clinical and health psychology at the UF College of Public Health and Health Professions, and Jamie Conti, M.D., an associate professor in the College of Medicine......... Posted by: Sean Permalink Source Laberge Study Shows Benefits Of Exercise
Laberge had modest expectations when she embarked on her research. "The Comite de gestion de la taxe scolaire de l'île de Montreal wanted to know if exercise would boost academic results," she reports. "But since there are thousands of factors affecting success, most importantly socio-economic status, family life, age and life experience, we didn't think that forty-five minutes of daily exercise would outweigh these overwhelming influences". Laberge and Paula Bush, whose work on the project constituted her master's research, set up an eighteen-week program of activities, including aerobic dance, martial arts, weight training, team sports and Playstation, for volunteer Secondary Two students at ecole Saint-Germain in Saint-Laurent. The study found a pronounced positive correlation between involvement in the program and the students' ability to pay attention and concentrate. But closer analysis of the findings revealed that the difference was observable only in male students because, Laberge believes, growing teenaged boys need an outlet for their high levels of energy.........

Laura told that the State Department has formed partnerships with the United Arab Emirates and Saudi Arabia to bring the latest information about the disease to these countries. Other countries like Morocco and Jordan might be joining the group soon, as discussion progress with these countries. "The progress we've made in the United States is exciting, but too a number of women around the world are still too embarrassed or too uninformed to seek the therapy they need in time to save their lives," Mrs. Bush said at a conference sponsored by the Susan G. Komen Breast Cancer Foundation, a partner in the effort......... Posted by: Sean Permalink Kylie Minogue Returns To Stage After Breast Cancer Fight
This was a surprise appearance for Kylie and she sang the chorus of Dannii's song "Jump To The Beat". Daily Mirror showed pictures of the two sisters hugging each other on the stage, with Minogue looking as radiant and sparkling as ever despite her fight against breast cancer. Kylie Minogue was diagnosed with breast cancer in May 2005 while she was preparing for the Australian leg of her Showgirl Tour.
