A new study reveals that spending on post-hospital care for patients who have traditional Medicare coverage costs much more than it does for an identical patient with private insurance. And despite the difference in cost, both patients have about the same clinical ending – as measured in their odds of ending up back in the hospital again, the study shows.
Transfusion of red blood cells (RBCs) stored anaerobically – in the absence of oxygen – is a promising technique to improve resuscitation from hemorrhagic shock, according to animal studies reported in SHOCK®: Injury, Inflammation, and Sepsis: Laboratory and Clinical Approaches, Official Journal of the Shock Society. The journal is published in the Lippincott portfolio by Wolters Kluwer.
A new study looking at incidence of disease data nationwide from 2000 to 2016 found a shift in obesity-associated cancers (OACs) to younger individuals. Typically, these cancers are diagnosed at higher rates among people older than 65. The most notable findings pertain to increases in these OACs among non-Hispanic Black and Hispanic women and men for whom certain cancers increased by 200-400%.

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.
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.
