It takes a community to lower cardiovascular risk
People in sixteen communities received usual care and those in 14 communities had an intervention that included the initiation and monitoring of treatments and controlling risk factors by non-physician health workers using computer tablet-based management algorithms and counselling; the provision of free antihypertensive and statin medicines recommended by non-physician health workers under supervision of physicians, and the involvement of a friend or family member to support adherence to medications and lifestyle advice.
Weight-Loss Surgery Associated with 40% Reduction in Risk of Death and Heart Complications in Patients with Diabetes and Obesity, Study Shows
A large Cleveland Clinic study shows that weight-loss surgery performed in patients with type 2 diabetes and obesity is associated with a lower risk of death and major adverse cardiovascular events than usual medical care. These patients also lost more weight, had better diabetes control, and used fewer medications for treatment of their diabetes and cardiovascular disease than those undergoing usual medical care.
The observational study looked at nearly 2,300 patients who underwent metabolic surgery and 11,500 matched patients with similar characteristics who received usual medical care.
Disaster Mental Health Resources Available Now for Hurricane Response and Recovery
Catastrophic natural disasters, such as hurricanes, cause extreme disruption and can be distressful for individuals, families and communities. Those receiving assistance as well as those involved in disaster management efforts can be affected. The Uniformed Services University of the Health Sciences’ Center for the Study of Traumatic Stress has released 12 new resources to aid in the response and recovery efforts for affected communities.
Researchers reveal how bacteria behind hospital infections block out antibiotics
Drug-resistant bacteria responsible for deadly hospital-acquired infections shut out antibiotics by closing tiny doors in their cell walls. The new finding by researchers at Imperial College London could allow researchers to design new drugs that ‘pick the locks’ of these…
