Self-assembling nanoparticle could improve MRI scanning for cancer diagnosis

Self-assembling nanoparticle could improve MRI scanning for cancer diagnosis

Scientists have designed a new self-assembling nanoparticle that targets tumours, to help doctors diagnose cancer earlier. The new nanoparticle, developed by researchers at Imperial College London, boosts the effectiveness of Magnetic Resonance Imaging (MRI) scanning by specifically seeking out receptors that are found in cancerous cells. The nanoparticle is coated with a special protein, which looks for specific signals given off by tumours, and when it finds a tumour it begins to interact with the cancerous cells. Continue reading

Minimally invasive heart stents prove safer

Minimally invasive heart stents prove safer

Researchers at the University of California, San Diego School of Medicine have documented the safety benefits of aortic stent grafts inserted during minimally invasive surgery to repair abdominal aortic aneurysms – weaknesses in the body’s largest artery that can rupture, causing potentially lethal internal bleeding. The study, published July 9 in JAMA Surgery , shows that patients who received the minimally invasive aortic repair procedure had a 42 percent reduction in preventable post-operative complications and a 72 percent reduction in mortality, compared with those who had undergone open repair surgery. The safety of the endovascular “inside blood vessel” procedure also appears to be improving over time, as researchers documented a 37 percent reduction in the likelihood of an avoidable complication between 2003 and 2010.

Ankle replacement becomes more common to relieve severe arthritis pain

Arthritis can cause terrible pain, making activities of daily living difficult, if not impossible. While most people are familiar with knee and hip replacement surgery for debilitating arthritis in these joints, ankle replacement is another procedure that’s on the rise for people suffering from severe ankle pain Continue reading

Among weight loss methods, surgery and drugs achieve highest patient satisfaction

Among weight loss methods, surgery and drugs achieve highest patient satisfaction

Obese and overweight Americans who have tried losing weight report far greater overall satisfaction with weight loss surgery and prescription weight loss medications than with diet, exercise and other self-modification methods, an Internet survey finds. The results were presented Saturday at the joint meeting of the International Society of Endocrinology and the Endocrine Society: ICE/ENDO 2014 in Chicago Continue reading

Bone loss persists two years after weight loss surgery

Bone loss persists two years after weight loss surgery

A new study shows that for at least two years after bariatric surgery, patients continue to lose bone, even after their weight stabilizes. The results — in patients undergoing gastric bypass, the most common type of weight loss surgery — were presented Monday at the joint meeting of the International Society of Endocrinology and the Endocrine Society: ICE/ENDO 2014 in Chicago. “The long-term consequences of this substantial bone loss are unclear, but it might put them at increased risk of fracture, or breaking a bone,” said Elaine Yu, MD, MSc, the study’s principal investigator and an endocrinologist at Massachusetts General Hospital, Boston.

Sensor in eye could track pressure changes, monitor for glaucoma

Your eye could someday house its own high-tech information center, tracking important changes and letting you know when it’s time to see an eye doctor. Continue reading

Clinical review of mixed urinary incontinence conducted

Clinical review of mixed urinary incontinence conducted

Many women experience bothersome urine loss with laughing, coughing and sneezing (stress urinary incontinence) AND on their way to the bathroom (urge urinary incontinence). When women experience both types of urine leakage, their condition is called mixed urinary incontinence. It is estimated that 20 to 36 percent of women suffer from mixed urinary incontinence, which is challenging to diagnose and treat because symptoms vary and guidelines for treatment are not clear.

Weight loss surgery also safeguards obese people against cancer

Weight loss surgery also safeguards obese people against cancer

Weight loss surgery might have more value than simply helping morbidly obese people to shed unhealthy extra pounds. It reduces their risk of cancer to rates almost similar to those of people of normal weight. Continue reading

Wound-healing role for microRNAs in colon offer new insight to inflammatory bowel diseases

Wound-healing role for microRNAs in colon offer new insight to inflammatory bowel diseases

A microRNA cluster believed to be important for suppressing colon cancer has been found to play a critical role in wound healing in the intestine, UT Southwestern cancer researchers have found. The findings, first discovered in mice and later reproduced in human cells, could provide a fresh avenue for investigating chronic digestive diseases and for potentially repairing damage in these and other disease or injury settings. “We identified a novel role for microRNAs in regulating wound healing in the intestine Continue reading
