A safe IV cannule to end needle injuries

M K Maan of Mecmaan Healthcare has come up with a safety intravenous cannule, a device that prevents needle stick injuries among healthcare workers.

It eliminates the chances of needle stick injuries and blood borne infections among the healthcare providers during the needle withdrawal and disposal. The cannule consists of seven detachable segments including a safety chamber that makes it different from other intravenous cannules available in the market. It is a hollow device attached to the back of the cannule, where the infected needle once withdrawn from the patient’s body gets automatically locked in thus preventing any kind of human touch.

Maan, a tool and die-making engineer said: “My design is completely safe. In this device, the infected needle is completely covered in a safety chamber and you can then easily dispose it under the clinical protocols.  

A ‘sausage skin’ to tackle most common forms of diabetes

Scientists have developed a sleeve implant that looks like a “giant sausage skin” to beat diabetes.

The 2ft-long device, developed as an incision-less alternative to a type of weight-loss surgery known as a duodenal switch, can reverse the disease within weeks, reports the Daily Mail.

The device, the EndoBarrier, is designed to have the same effects as surgery but is far safer. It is a plastic sleeve that lines the duodenum, meaning food can only be absorbed lower down the intestine.

The procedure is performed under anaesthetic in less than an hour. The sleeve—made from a thin plastic—is inserted via the mouth and passed into the digestive tract using a thin tube.

Once in place, a sprung titanium anchor prevents it slipping out. It is removed after a year.

Initially experts believed it was a result of weight loss – but many patients were able to stop taking their diabetes medication before they began to lose weight.

Non-hereditary mutations behind schizophrenia cases

More than 50 percent of sporadic cases of schizophrenia are caused by new, or “de novo,” protein-altering mutations—genetic errors that are present in patients but not in their parents, a research has shown.

A group of doctors examined the genomes of patients with schizophrenia and their families, as well as healthy control groups. All were from the genetically isolated, European-descent Afrikaner population of South Africa. They found 40 mutations, all from different genes and most of them protein-altering. The results point the way to finding more, perhaps even hundreds, of mutations that contribute to the genetics of schizophrenia—a necessary step toward understanding how the disease develops, the researchers said.

“Identification of these damaging de novo mutations has fundamentally transformed our understanding of the genetic basis of schizophrenia,” says Bin Xu, PhD, assistant professor of clinical neurobiology at Columbia University Medical Center and first author of the study.
