Severing nerves may shrink stomach cancers: Botox injections slow growth of stomach tumors in mice

Severing nerves may shrink stomach cancers: Botox injections slow growth of stomach tumors in mice

Research from Columbia University Medical Center shows that nerves may play a critical role in stomach cancer growth and that blocking nerve signals using surgery or Botox® (onabotulinumtoxinA) could be an effective treatment for the disease. Continue reading

Promise for new nerve repair technique

Promise for new nerve repair technique

A multicenter study including University of Kentucky researchers found that a new nerve repair technique yields better results and fewer side effects than other existing techniques. Continue reading

New hand-held device uses lasers, sound waves for deeper melanoma imaging

New hand-held device uses lasers, sound waves for deeper melanoma imaging

A new hand-held device that uses lasers and sound waves may change the way doctors treat and diagnose melanoma, according to a team of researchers from Washington University in St. Louis. The instrument, described in a paper published today in The Optical Society’s (OSA) journal Optics Letters , is the first that can be used directly on a patient and accurately measure how deep a melanoma tumor extends into the skin, providing valuable information for treatment, diagnosis or prognosis.

‘Treatments waiting to be discovered’ inside new database

‘Treatments waiting to be discovered’ inside new database

Your genes are blueprints for proteins, and molecules called microRNA can help to determine how often these genetic blueprints are manufactured into proteins. Researchers often ask what microRNA regulates a gene related to disease. Or what gene is regulated by a microRNA found in sick patients Continue reading

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

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.
