Factors tied to perioperative visual loss implicate optical canal venous congestion Posted: 03 Jan 2012 04:00 PM PST Factors including obesity, Wilson frame use, long duration of anesthesia, and large estimated blood loss increase patients' risk for ischemic optic neuropathy after spinal fusion surgery, report researchers.

Highly sensitive troponin I assay helps determine diagnosis of MI Posted: 03 Jan 2012 04:00 PM PST Use of a highly sensitive test for troponin I levels could help determine the diagnosis of myocardial infarction within a few hours of admission for chest pain, a study has found.

Insulin resistance linked to hypertension in children Posted: 03 Jan 2012 04:00 PM PST Insulin resistance is independently associated with hypertension in children, a group of Italian researchers suggests.

Sitagliptin stimulates GLP-1 release independently of DPP-IV action Posted: 03 Jan 2012 04:00 PM PST Study findings demonstrate that sitagliptin directly stimulates glucagon-like peptide-1 secretion from intestinal L cells, independently of its effect on dipeptidylpeptidase-IV.

Severe disease phenotype in ARH linked to LDLRAP1 double mutation Posted: 03 Jan 2012 04:00 PM PST Study findings suggest that patients with autosomal recessive hypercholesterolemia who have a particularly severe disease phenotype in terms of xanthoma and atherosclerotic cardiovascular disease are likely to have an additional mutation in the low-density lipoprotein receptor adaptor protein 1 gene.

HDRS may underestimate depression severity in BD patients Posted: 03 Jan 2012 04:00 PM PST The Hamilton Depression Rating Scale may underestimate the severity of depressive symptoms in patients with bipolar disorder, warn Korean researchers.

Supported employment programs benefit older patients with schizophrenia Posted: 03 Jan 2012 04:00 PM PST Results from a US study show that middle-aged and older patients with schizophrenia benefit from supported employment programs.

Diabetes effectively managed by community health workers Posted: 02 Jan 2012 04:00 PM PST Diabetes and hypertension can be effectively managed in middle-income countries through use of primary care systems with trained community healthcare workers and well-established guidelines, shows a study from Iran.
