Weight reduction among people with severe and persistent mental illness after health behavior counseling and monitoring.

The high prevalence of obesity and associated chronic conditions in persons with severe and persistent mental illness has contributed to a mortality rate that is nearly two times higher than the overall population. In 2008, the Central O'ahu Community Mental Health Center of the Hawai'i State Department of Health, Adult Mental Health Division began an unfunded, health counseling intervention pilot project to address such concerns for the health of persons with severe and persistent mental illness. This article reviews the results of this intervention.

Familial thoracic aortic aneurysms and dissections: identification of a novel locus for stable aneurysms with a low risk for progression to aortic dissection.

Background: Thoracic aortic aneurysms leading to acute aortic dissections are the major diseases that affect the thoracic aorta. Approximately 20% of patients with thoracic aortic aneurysms and dissections (TAAD) have a family history of TAAD, and these patients present younger with more rapidly enlarging aneurysms than patients without a family history of aortic disease.

Methods And Results: A large family with multiple members with TAAD inherited in an autosomal-dominant manner was identified.

Oxidation and haem loss kinetics of poly(ethylene glycol)-conjugated haemoglobin (MP4): dissociation between in vitro and in vivo oxidation rates.

Haemoglobin-based oxygen carriers can undergo oxidation of ferrous haemoglobin into a non-functional ferric form with enhanced rates of haem loss. A recently developed human haemoglobin conjugated to maleimide-activated poly(ethylene glycol), termed MP4, has unique physicochemical properties (increased molecular radius, high oxygen affinity and low cooperativity) and lacks the typical hypertensive response observed with most cell-free haemoglobin solutions. The rate of in vitro MP4 autoxidation is higher compared with the rate for unmodified SFHb (stroma-free haemoglobin), both at room temperature (20-22 degrees C) and at 37 degrees C (P<0.

Venous outflow and inflow resistance in health and venous disease.

Purpose: The purpose of this study was to develop a physiologic method to measure outflow and inflow from the lower extremities and thus to quantify the degree of venous valvular insufficiency and venous obstructive disease.

Methods: Calibrated photoplethysmography was used in combination with passive changes in hydrostatic pressure, by leg elevation followed by repositioning of the leg to the original sitting position. With the principle of venous occlusion plethysmography, timed volume changes were then used to calculate the outflow and inflow.

Effects of pentachlorophenol and other chemical preservatives on the health of wood-treating workers in Hawaii.

The morbidity and mortality of workers occupationally exposed to wood treating chemicals used in Hawaii for the years 1960 to 1981 were evaluated. The specific chemical exposures investigated were CCA (chromated copper-arsenate), TBTO (tributyl tin oxide) and PCP (pentachlorophenol). Results of detailed medical histories, laboratory and physiological tests, and physical examinations of 88 wood treaters were compared with those of 58 matched controls.
