New way to diagnose malaria by detecting parasite’s waste in infected blood cells

New way to diagnose malaria by detecting parasite’s waste in infected blood cells

Over the past several decades, malaria diagnosis has changed very little. After taking a blood sample from a patient, a technician smears the blood across a glass slide, stains it with a special dye, and looks under a microscope for the Plasmodium parasite, which causes the disease.

Wine only protects against CVD in people who exercise

Wine only protects against CVD in people who exercise

Wine only protects against cardiovascular disease (CVD) in people who exercise, according to results from the In Vino Veritas (IVV) study presented at ESC Congress today by Professor Milos Taborsky from the Czech Republic. Professor Taborsky said: “This is the first randomised trial comparing the effects of red and white wine on markers of atherosclerosis in people at mild to moderate risk of CVD. We found that moderate wine drinking was only protective in people who exercised. Continue reading

Surprising discovery: HIV hides in gut, evading eradication

Surprising discovery: HIV hides in gut, evading eradication

Researchers at UC Davis have made some surprising discoveries about the body’s initial responses to HIV infection. Studying simian immunodeficiency virus (SIV), the team found that specialized cells in the intestine called Paneth cells are early responders to viral invasion and are the source of gut inflammation by producing a cytokine called interleukin-1 beta (IL-1β).

Options for weight loss your primary care doctor might not know about

Options for weight loss your primary care doctor might not know about

Despite US Preventive Services Task Force recommendations for screening and treating obesity, there are many barriers, several of which may be ameliorated through technological approaches according to a new study by researchers at NYU Langone Medical Center published online August 21, 2014 in the Journal of General Internal Medicine (JGIM). David Levine, MD, MA, a third year resident in the Department of Internal Medicine at NYU Langone Medical Center, and colleagues found that compared to usual care, technology-assisted interventions specifically in the primary care setting help patients achieve weight loss.

New model predicts patients with type 1 diabetes who will go on to develop major complications

New model predicts patients with type 1 diabetes who will go on to develop major complications

New research published in Diabetologia (the journal of the European Association for the Study of Diabetes) presents a new model for predicting which patients with type 1 diabetes will go on to develop major complications, through easily and routinely measured risk factors. The research is by Assistant Professor Sabita Soedamah-Muthu, Wageningen University, Netherlands, and colleagues. To create the model, data were analysed from 1,973 participants with type 1 diabetes followed for seven years in the EURODIAB Prospective Complications Study, and strong prognostic factors of major outcomes were combined into a computer model Continue reading

Second-hand e-cig smoke compared to regular cigarette smoke

Second-hand e-cig smoke compared to regular cigarette smoke

Despite a 10-fold decrease in overall exposure to carcinogenic particulate matter, researchers find increased levels of certain toxic metals in second-hand smoke from e-cigs. E-cigarettes are healthier for your neighbors than traditional cigarettes, but still release toxins into the air, according to a new study from USC. Scientists studying secondhand smoke from e-cigarettes discovered an overall 10-fold decrease in exposure to harmful particles, with close-to-zero exposure to organic carcinogens. Continue reading

Home is where the microbes are

A person’s home is their castle, and they populate it with their own subjects: millions and millions of bacteria. A study published tomorrow in Science provides a detailed analysis of the microbes that live in houses and apartments. Continue reading

Genomic sequencing reveals mutations, insights into 2014 Ebola outbreak

Genomic sequencing reveals mutations, insights into 2014 Ebola outbreak

In response to an ongoing, unprecedented outbreak of Ebola virus disease (EVD) in West Africa, a team of researchers from the Broad Institute and Harvard University, in collaboration with the Sierra Leone Ministry of Health and Sanitation and researchers across institutions and continents, has rapidly sequenced and analyzed more than 99 Ebola virus genomes. Their findings could have important implications for rapid field diagnostic tests. The team reports its results online in the journal Science . Continue reading
