Researchers have launched an early-stage human clinical trial of two related candidate vaccines to prevent infection with Shigella, bacteria that are a significant cause of diarrheal illness, particularly among children. The Phase I clinical trial, funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, will evaluate the vaccines for safety and their ability to induce immune responses among 90 healthy adults ages 18 to 45 years. The trial is being conducted at the Cincinnati Children's Hospital Medical Center, one of the eight NIAID-funded Vaccine and Treatment Evaluation Units in the United States. http://medicalxpress.com/news/2013-02-trial-shigella-vaccine-candidates.html Medications Wed, 20 Feb 2013 13:20:41 EST news280588830 `In a study to be presented on February 14 at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting, in San Francisco, California, researchers will present data showing the effectiveness of preemptive treatment for hyperemesis gravidarum and severe morning sickness. http://medicalxpress.com/news/2013-02-preemptive-treatment-severe-morning-sickness.html Obstetrics & gynaecology Mon, 11 Feb 2013 10:36:41 EST news279800895 A genetically-engineered virus tested in 30 terminally-ill liver cancer patients significantly prolonged their lives, killing tumours and inhibiting the growth of new ones, scientists reported on Sunday. http://medicalxpress.com/news/2013-02-genetically-virus-cancer.html Cancer Sun, 10 Feb 2013 15:08:22 EST news279731294 (HealthDay News) —A skin patch for the treatment of migraines, and the intense waves of nausea that often accompany these debilitating headaches, has been approved by the U.S. Food and Drug Administration. http://medicalxpress.com/news/2013-01-fda-skin-patch-combat-migraines.html Diseases, Conditions, Syndromes Mon, 21 Jan 2013 16:03:16 EST news278006588 (HealthDay)—Insured Americans with serious medical conditions say the financial stress of rising out-of-pocket health care costs is forcing them to juggle household budgets, delay or skimp on care and even run up credit cards or dodge debt collectors, a new study reveals. http://medicalxpress.com/news/2013-01-high-medical-bills-americans-extreme.html Health Fri, 18 Jan 2013 11:10:01 EST news277728121 (HealthDay)—Here's a new twist on the old idea of not letting anything go to waste.
