Blue dye tablet helps identify polyps during colonoscopy

Mon, 2018-05-21 21:00
(Digestive Disease Week) Ingestion of a blue dye tablet during bowel prep for colonoscopy could be a significant advance in the early detection of colorectal cancer (CRC). When used in conjunction with colonoscopy, the blue dye increased adenoma detection rate (ADR) by nearly 9 percent, according to a study scheduled for presentation at Digestive Disease Week® (DDW) 2018.

New study sheds light on the opioid epidemic and challenges prevailing views about this public health crisis

Mon, 2018-05-21 21:00
(Elsevier) A study published in the American Journal of Preventive Medicine sheds new light on the sharp rise in fatal drug overdoses in recent years, one of the most severe public health challenges of our time. The study found that the growth in fatal overdoses for non-Hispanic whites (NHWs) aged 22-56 years was sufficiently large to account for the entire growth in mortality rates (MR) and years of potential life lost (YPLL) for this population from 1999 to 2015.

More patients with severe alcoholic hepatitis receiving liver transplants

Mon, 2018-05-21 21:00
(Digestive Disease Week) Increasingly, liver transplant centers are changing a long-standing practice of delaying potentially life-saving liver transplantation for patients with severe alcoholic hepatitis until after they stopped drinking alcohol for six months, according to a new study scheduled for presentation at Digestive Disease Week® (DDW) 2018.

Procedure plus medication is better than standard treatment for heart disease patients

Mon, 2018-05-21 21:00
(St. Michael's Hospital) A non-surgical procedure, called percutaneous coronary intervention (PCI), along with prescribed medication, is better than medication alone as initial treatment for people who have the most common form of heart disease, suggests an analysis of an international clinical trial co-led by St. Michael's Hospital.

DNA-based vaccine treatment for colorectal cancer to undergo first human study

Mon, 2018-05-21 21:00
(Digestive Disease Week) Combining a DNA vaccine, which boosts the body's immune response against tumors, with an antibody that blocks the body's natural defense against the potency of the DNA vaccine, may lead to the development of an effective treatment for late stage colorectal cancer, when a cure is not often possible. Preliminary research leading up to this trial will be presented at Digestive Disease Week® 2018.

Experimental drug eases effects of gluten for celiac patients on gluten-free diet

Mon, 2018-05-21 21:00
(Digestive Disease Week) An investigational new drug offers hope of relief for celiac disease patients who are inadvertently exposed to gluten while on a gluten-free diet. Findings of the first phase 2 study of a biologic immune modulator in celiac disease will be presented at the upcoming Digestive Disease Week® (DDW) 2018. Inadvertent exposure to gluten can be a frequent occurrence for celiac patients that triggers symptoms, such as pain in the gut and diarrhea, due to intestinal damage.

SYNTAX III Revolution trial

Mon, 2018-05-21 21:00
(PCR) Results from the innovative SYNTAX III Revolution trial underline the effectiveness of evolving non-invasive algorithms for Heart Team decision making using state-of-the-art imaging. A distinctive clinical trial in that it randomised the doctors -- in this case, the Heart Team -- rather than the patient, the goal was to better understand the present and future role that non-invasive assessments could play in deciding and planning revascularisation strategies.

FFR-guided PCI vs. medical therapy to reduce cardiac death and myocardial infarction

Mon, 2018-05-21 21:00
(PCR) Results from the first patient-level pooled analysis of all existing trials comparing FFR-guided PCI with contemporary stents versus medical therapy demonstrates improved hard outcomes. In patients with stable coronary lesions, contemporary PCI -- i.e., guided by FFR -- reduces the risk of future myocardial infarction or cardiac death independently of its impact on symptoms.

Physiology-stratified analysis of ORBITA

Mon, 2018-05-21 21:00
(PCR) Results from the physiology-stratified analysis of ORBITA presented at EuroPCR 2018 and simultaneously published in Circulation demonstrate that PCI improves ischaemia as assessed by dobutamine stress echocardiography, renders more patients free of angina than does placebo and that FFR and iFR do predict the strength of the PCI effect on ischaemia, but this is only clearly seen on blinded stress echo evaluation. It is not visible in the symptom scores or exercise times.

Link between tuberculosis and Parkinson's disease discovered

Mon, 2018-05-21 21:00
(The Francis Crick Institute) The mechanism our immune cells use to clear bacterial infections like tuberculosis (TB) might also be implicated in Parkinson's disease, according to a new study. The findings provide a possible explanation of the cause of Parkinson's disease and suggest that drugs designed to treat Parkinson's might work for TB too.

UCI researchers discover novel mode of neurotransmitter-based communication

Sun, 2018-05-20 21:00
(University of California - Irvine) This is the first example of a novel mode of neurotransmitter-based communication and challenges current dogma about mechanisms of signaling in the brain. The findings uncover new pathways for developing therapies for disorders like epilepsy, anxiety and chronic pain.

The vessel not taken: Understanding disproportionate blood flow

Sun, 2018-05-20 21:00
(American Institute of Physics) Each time a blood vessel splits into smaller vessels, red blood cells (RBCs) are presented with the same decision: Take the left capillary or the right. While one might think RBCs would divide evenly at every fork in the road, it is known that at some junctures, RBCs seem to prefer one vessel over the other. One new computer model looks to determine why RBCs behave this way, untangling one of the biggest mysteries in our vascular system

What can snakes teach us about engineering friction?

Sun, 2018-05-20 21:00
(Drexel University) If you want to know how to make a sneaker with better traction, just ask a snake. That's the theory driving the research of Hisham Abdel-Aal, PhD, an associate teaching professor from Drexel University's College of Engineering who is studying snake skin to help engineers improve the design of textured surfaces, such as engine cylinder liners, prosthetic joints - and yes, maybe even footwear.

Deep space radiation treatment reboots brain's immune system

Sun, 2018-05-20 21:00
(University of California - San Francisco) NASA and private company SpaceX plan to send humans to Mars within the next 15 years--but need to figure out how to protect astronauts from the dangerous cosmic radiation of deep space. Now the lab of UCSF neuroscientist Susanna Rosi, PhD, has identified a potential treatment for the brain damage caused by cosmic rays--a drug that prevents memory impairment in mice exposed to simulated space radiation. The study was published May 18, 2018 in Scientific Reports.
