The ability of human cytochromes P450 other than CYP2E1 to catalyse the 6-hydroxylation of chlorzoxazone (6-OH-CHZ) was examined in vitro using human liver microsomal preparations and in vivo using chlorzoxazone as a metabolic probe. Chlorzoxazone 6-hydroxylation activity was significantly correlated with 4-nitrophenol 2-hydroxylase activity and(More)
BACKGROUND Massive transfusion protocols (MTPs) have become standard of care in the management of bleeding injured patients, yet strategies to guide them vary widely. We conducted a pragmatic, randomized clinical trial (RCT) to test the hypothesis that an MTP goal directed by the viscoelastic assay thrombelastography (TEG) improves survival compared with an(More)
The D7 subfamily of salivary proteins is widespread in blood sucking Diptera and belongs to the superfamily of pheromone/odourant binding proteins. Although D7 proteins are among the most abundant salivary proteins in adult female mosquitoes and sand flies, their role in blood feeding remains elusive. In the present work we report the sequence of seventeen(More)
Postinjury fibrinolysis can manifest as three distinguishable phenotypes: 1) hyperfibrinolysis, 2) physiologic, and 3) hypofibrinolysis (shutdown). Hyperfibrinolysis is associated with uncontrolled bleeding due to clot dissolution; whereas, fibrinolysis shutdown is associated with organ dysfunction due to microvascular occlusion. The incidence of(More)
INTRODUCTION The mechanisms driving trauma-induced coagulopathy (TIC) remain to be defined, and its therapy demands an orchestrated replacement of specific blood products. Thrombelastography (TEG) is a tool to guide the TIC multicomponent therapy. Principal component analysis (PCA) is a statistical approach that identifies variable clusters; thus, we(More)
BACKGROUND Policymakers question whether there is a relationship between the number and distribution of physicians and the outcomes for important health conditions. We hypothesized that increasing primary care physician supply would be related to earlier detection of colorectal cancer. METHODS We identified incident cases of colorectal cancer occurring in(More)
BACKGROUND Comorbidity may be associated with later detection of cancer. METHODS Incident cases of colorectal, breast, and prostate cancer and melanoma were determined from the 1994 Florida state tumor registry (N = 32,074). The relationship between comorbidity and late stage at diagnosis was examined using multiple logistic regression. RESULTS Patients(More)
BACKGROUND Primary care physician (PCP) services may have an impact on breast cancer mortality and incidence, possibly through greater use of screening mammography. METHODS The authors conducted a retrospective, 1:1 matching case-control study using the Surveillance, Epidemiology, and End Results (SEER)-Medicare-linked database to examine use of PCP(More)
BACKGROUND Despite increasingly widespread use of the Papanicolaou smear, almost half of all women with invasive cervical cancer are diagnosed at a late stage (regional or distant). Little is known about factors associated with late-stage diagnosis of cervical cancer. OBJECTIVE To examine the relationship of age, race, education level, income level,(More)
BACKGROUND Predicting refractory coagulopathy early in resuscitation of injured patients may decrease a leading cause of preventable death. We hypothesized that clot strength (G) measured by point-of-care rapid thrombelastography (r-TEG) on arrival in the emergency department can predict massive transfusion (MT) and coagulation-related mortality (MT-death).(More)
