BACKGROUND Prophylactic use of low molecular weight heparin (LMWH) has been shown to be efficacious in decreasing thromboembolism. LMWHs are associated with increased rates of bleeding. OBJECTIVE We reviewed perioperative blood pressure dynamics for patients who experienced hematomas while undergoing body contouring procedures while receiving enoxaparin (Lovenox), compared with similar patien...

INTRODUCTION A pneumatic tube system (PTS) is a cost-effective, rapid transport modality that utilizes induced pressure changes. We evaluated the clinical importance of 2 transport modalities, human courier and PTS, for blood gas specimens. METHODS Following open heart surgery, 35 simultaneous pairs of arterial and venous blood gas specimens were analyzed from 20 subjects. Of each pair, one s...

BACKGROUND The prognostic significance of modest elevations in exercise systolic blood pressure response has not been extensively examined. METHODS AND RESULTS We examined the association between systolic blood pressure response and all-cause death and incident myocardial infarction (MI) in 44 089 (mean age 53±13 years, 45% female, 26% black) patients who underwent exercise treadmill stress t...

PURPOSE A meta-analysis of randomized trials studying the effect of nonsteroidal anti-inflammatory drugs (NSAIDs) on blood pressure. DATA SOURCES AND STUDY SELECTION Eight databases were searched, yielding 38 randomized, placebo-controlled trials and 12 randomized but not placebo-controlled trials (comparing two or more NSAIDs). DATA EXTRACTION Pooled mean treatment effects were computed in...

A prevalent environmental contaminant, mercury (Hg) is mobile and persistent in aquatic systems, where it often occurs in its bioavailable form methylmercury. Because methylmercury can bioaccumulate in aquatic insects and then transfer to terrestrial food webs, riparian consumers reliant upon aquatic emergent insects, should be disproportionately affected. Using the aerial insectivore Acadian f...

Introduction: During the past four decades, mercury (Hg) research focused on fish consumption has explained less than 22% of Hg in human blood. One overlooked exposure pathway for infants and young children is the concentration of Hg in soils. Although 75% of the US population lives in urban areas near industrial facilities, minimal data exist regarding the concentration and speciation of Hg in...

The clinical significance of measuring central arterial blood pressure has been recently discussed. Although the postprandial reduction in blood pressure is well known, postprandial changes in central blood pressure have not been intensively studied. The present study investigated differences in the reduction of central and peripheral arterial blood pressure after administration of an oral gluc...

Cerebrovascular concentrations of prostaglandin E (PGE), prostaglandin F2 alpha (PGF2 alpha), 6-ketoprostaglandin F1 alpha (6-keto-PGF1 alpha), and thromboxane B2 (TXB2) were determined over a blood pressure range of 17-117 mm Hg (induced by inflation of balloon-tipped catheters placed in the thoracic descending aorta and at the aortic root) in eight newborn piglets to access the role of prosta...

BACKGROUND In 2014, new hypertension guidelines liberalized blood pressure goals for persons 60 years and older. Little is known about the implications for blacks. METHODS AND RESULTS Using data from 2000 through 2011 for 5280 participants in the Jackson Heart Study, a community-based black cohort in Jackson, Mississippi, we examined whether higher blood pressure was associated with greater r...
