Stumped for years by a natural filter in the body that allows few substances, including life-saving drugs, to enter the brain through the bloodstream, physicians who treat neurological diseases may soon have a new pathway to the organ via a technique developed by a physicist and an immunologist working together at Florida International University's Herbert Wertheim College of Medicine. http://medicalxpress.com/news/2013-05-fiu-pathway-brain-medicine.html Medical research Mon, 06 May 2013 18:26:42 EST news287083592 (HealthDay)—Extracts of saw palmetto berry used at doses of up to 960 mg daily appear to be safe over an 18-month period, according to a study published in the April issue of The Journal of Urology. http://medicalxpress.com/news/2013-04-high-doses-palmetto-safe-months.html Diseases, Conditions, Syndromes Mon, 29 Apr 2013 20:00:01 EST news286482322 (HealthDay)—Physicians do not order fewer imaging tests if they are aware of the costs, according to a study published online Jan. 2 in the Journal of the American College of Radiology. http://medicalxpress.com/news/2013-02-imaging-doesnt.html Health Fri, 01 Feb 2013 12:50:01 EST news278943981 Blood levels of an immunity-related protein, galectin-1, in patients with newly diagnosed Hodgkin lymphoma reflected the extent of their cancer and correlated with other predictors of outcome, scientists reported at the American Society of Hematology annual meeting. http://medicalxpress.com/news/2012-12-blood-immune-protein-hodgkin-disease.html Cancer Mon, 10 Dec 2012 16:06:29 EST news274377950 A University of Cincinnati (UC) Cancer Institute lung cancer research team reports that lung cancer stem cells can be isolated—and then grown—in a preclinical model, offering a new avenue for investigating immunotherapy treatment options that specifically target stem cells. http://medicalxpress.com/news/2012-11-stem-cell-advance-immunotherapy-lung.html Cancer Tue, 13 Nov 2012 17:00:02 EST news272044430 (Medical Xpress)—Researchers from the University of Otago, Christchurch, are collaborating with clinicians at Fertility Associates in Christchurch to develop a test to significantly improve the success rate for in vitro fertilisations implantations. http://medicalxpress.com/news/2012-10-discovery-success-ivf.html Obstetrics & gynaecology Mon, 01 Oct 2012 09:22:59 EST news268302169 (Medical Xpress)—If your dinner date chooses unhealthily from a restaurant menu, you are less likely to stick to healthy options, according to University of Birmingham research published in the British Journal of Nutrition. http://medicalxpress.com/news/2012-09-dinner-date-weight.html Overweight and Obesity Tue, 04 Sep 2012 17:28:35 EST news265998453 A novel blood test that predicts sudden death risk in heart failure patients is set to help physicians decide which patients would benefit from implantable cardioverter defibrillators (ICDs). The findings were presented at the ESC Congress 2012 today, August 26, by Professor Samuel Dudley from Chicago, IL, US. http://medicalxpress.com/news/2012-08-blood-sudden-death-patients-benefit.html Cardiology Mon, 27 Aug 2012 10:38:38 EST news265282713 A laboratory study led by UNC medical oncologist Stergios Moschos, MD, demonstrates how a new targeted drug, Elesclomol, blocks oxidative phosphorylation, which appears to play essential role in melanoma that has not been well-understood. Elesclomol (Synta Pharmaceuticals, Lexington, MA) was previously shown to have clinical benefit only in patients with normal serum lactate dehydrogenase (LDH), a laboratory test routinely used to assess activity of disease. http://medicalxpress.com/news/2012-08-reveals-molecular-melanoma-treatment.html Cancer Fri, 17 Aug 2012 23:17:06 EST news264464196 Because there is currently no laboratory test that can diagnose Parkinson's disease, it is practically impossible to detect those individuals who are in the earliest stages of the disease. As a result, Parkinson's disease can only be diagnosed by a clinical neurological examination based on findings suggestive of the disease. http://medicalxpress.com/news/2012-06-id-cluster-genes-blood-parkinson.html Parkinson's & Movement disorders Tue, 05 Jun 2012 08:29:30 EST news258103741 Researchers from the Georgia Institute of Technology and the Centers for Disease Control and Prevention (CDC) have developed a new laboratory test that can rapidly identify the bacterium responsible for staph infections. This new test takes advantage of unique isotopic labeling combined with specific bacteriophage amplification to rapidly identify Staphylococcus aureus. http://medicalxpress.com/news/2012-01-laboratory-method-mass-spectrometry-rapidly.html Medical research Thu, 12 Jan 2012 10:50:01 EST news245586293 A universal method of identifying medical test results and other clinical measurements is essential for health information exchange, which requires a common terminology to ensure that medical data can be recorded, transferred and ultimately used when and where the patient needs it. http://medicalxpress.com/news/2011-12-lingua-franca-critical-electronic-medical.html Health Thu, 22 Dec 2011 12:48:14 EST news243780485 (Medical Xpress) -- A cheaper laboratory test that helps guide anti-retroviral drug treatment for people with HIV/AIDS may be just as effective as a more sophisticated test, a group of international researchers has found – a discovery that could be particularly important in rural Africa. http://medicalxpress.com/news/2011-12-blood-cell-hiv-treatment-cheaper.html HIV & AIDS Thu, 01 Dec 2011 04:50:01 EST news241936317 Pipe-in-pipe systems are now commonly used to distribute water in many homes. The inner pipe for drinking water is made of a plastic called cross-linked polyethylene (PEX). Are these pipes harmful to health and do they affect the taste and odour of drinking water? http://medicalxpress.com/news/2011-11-plastic-pipes-.html Health Tue, 08 Nov 2011 12:06:39 EST news239976391 Two studies by a team of researchers led by Luis E. Cuevas and Mohammed Yassin from the Liverpool School of Tropical Medicine and jointly coordinated with Andrew Ramsay at WHO-TDR Special Programme for Research and Training in Tropical Diseases are published in this week's PLoS Medicine. The studies have important implications for the ways in which diagnosis for the endemic infectious disease, tuberculosis (TB), can be done in poor countries. One study suggests that less sputum tests collected the same day of consultation are needed and the other suggests that a faster laboratory test can be used while maintaining the same level of accuracy for diagnosis. Both studies show that alternative, less labour-intensive tests that are more convenient for patients could be effectively used in poorer countries. http://medicalxpress.com/news/2011-07-alternative-methods-smear-effective-tb.html Diseases, Conditions, Syndromes Tue, 12 Jul 2011 17:32:44 EST news229710752 Today, the Association for Molecular Pathology (AMP) released its new position statement on the appropriate manner to reference diagnostic tests in drug labels. The association also met with officials from the United States Food and Drug Administration that participate in the effort to draft guidance documents for co-developed products and companion diagnostics to inform them of its new position statement. http://medicalxpress.com/news/2011-05-amp-statement-diagnostics-drug.html Medications Mon, 16 May 2011 11:10:01 EST news224761676
