Researchers say monitoring such changes in small blood vessels early in pregnancy may allow for medical intervention long before the potentially life-threatening condition occurs. http://medicalxpress.com/news/2013-03-marker-preeclampsia-pregnancy.html Cardiology Thu, 07 Mar 2013 12:31:35 EST news281881887 (HealthDay)—A new model to predict lung cancer risk is more accurate than previous criteria, according to a study published in the Feb. 21 issue of the New England Journal of Medicine. http://medicalxpress.com/news/2013-02-accurately-lung-cancer.html Cancer Fri, 22 Feb 2013 10:40:01 EST news280751066 (HealthDay)—Data from electronic health records (EHRs) can be used to detect more cases of diabetes than claim codes alone and can be used to accurately distinguish between type 1 and type 2 diabetes, according to a study published online Nov. 27 in Diabetes Care. http://medicalxpress.com/news/2012-12-ehr-algorithm-diabetes.html Diabetes Mon, 10 Dec 2012 17:00:02 EST news274378998 In a column appearing in the current issue of the journal Nature, McLean Hospital biostatistician Nicholas Lange, ScD, cautions against heralding the use of brain imaging scans to diagnose autism and urges greater focus on conducting large, long-term multicenter studies to identify the biological basis of the disorder. http://medicalxpress.com/news/2012-11-brain-imaging-autism.html Autism spectrum disorders Fri, 02 Nov 2012 12:17:34 EST news271077435 (HealthDay)—In children under the age of 3, a high dot-blot count for retinal hemorrhages (RHs) is a strong predictor of inflicted traumatic brain injury (ITBI) rather than accidental traumatic brain injury (ATBI), according to research published online Oct. 8 in Pediatrics. http://medicalxpress.com/news/2012-10-retinal-hemorrhage-pattern-inflicted-brain.html Pediatrics Tue, 09 Oct 2012 19:30:01 EST news269024247 Not all head and neck cancers are created equal. Those started by infection with the human papillomavirus are less often fatal than those with other causes, such as smoking. Detection of a reliable fingerprint for HPV could help patients avoid unnecessarily harsh treatment. A new study finds that while one popular biomarker for HPV is not a reliable predictor of mortality from the cancers alone, combinations of some biomarkers showed much more promise. http://medicalxpress.com/news/2012-09-hpv-biomarkers-neck-cancers-combinations.html Cancer Tue, 18 Sep 2012 13:00:01 EST news267187425 (HealthDay)—Using a glycated hemoglobin (HbA1c) threshold of ≥6.5 percent is a specific but not sensitive early indicator of type 1 diabetes (T1D) in high-risk children and young adults, according to a study published in the September issue of Diabetes Care. http://medicalxpress.com/news/2012-09-hba1c-percent-specific-sensitive-t1dm.html Diseases, Conditions, Syndromes Sun, 02 Sep 2012 04:50:02 EST news265778778 Using a new assay method to study tumor cells, researchers at the University of California, San Diego School of Medicine and UC San Diego Moores Cancer Center have found evidence of clonal evolution in chronic lymphocytic leukemia (CLL).

For example, if a person puts his hand in a fire and gets burned, he learns to avoid flames; the simple sight of a flame has acquired a predictive value, which in this case, is repulsive. To learn more about such neural adaptability, researchers at the California Institute of Technology (Caltech) have explored the brains of insects and identified a mechanism by which the connections in their brain change to form new and specific memories of smells. http://medicalxpress.com/news/2012-01-mechanism-associative-memory-exploring-insect.html Neuroscience Thu, 26 Jan 2012 13:56:02 EST news246808549 In the largest reported series yet to compare transcervical extended mediastinal lymphadenectomy (TEMLA) with endoscopic and surgical primary staging and restaging of non-small cell lung cancer (NSCLC), TEMLA showed a significantly higher diagnostic yield, according to research presented at the 14th World Conference on Lung Cancer in Amsterdam, hosted by the International Association for the Study of Lung Cancer (IASLC). http://medicalxpress.com/news/2011-07-temla-higher-diagnostic-yield-ebus.html Cancer Thu, 07 Jul 2011 06:42:06 EST news229239703
