OBJECTIVE The purpose of the study was to determine the effectiveness of a social support intervention delivered to pregnant adolescent girls between 32 and 36 weeks of gestation in preventing symptoms of depression at 6 weeks postpartum. DESIGN The study used a repeated measures design. SETTING Data were collected at a teenage parenting program, an(More)
BACKGROUND The dose response relationship of warfarin is unpredictable. Polymorphism of the Cytochrome P4502C9 enzyme leads to warfarin hypersensitivity presumably due to decreased metabolism of the S-enantiomer. The purpose of this study was to further characterize the relationship between CYP2C9 genotype and phenotype and to develop a basis for guidelines(More)
BACKGROUND Antiphospholipid syndrome (APS) is a disorder of recurrent venous or arterial thrombosis, pregnancy losses, and thrombocytopenia. Recurrent thrombosis has particularly adverse effects on patients prognosis. The factors that influence recurrence and management techniques that prevent these events remain controversial. To add further insight(More)
BACKGROUND Semaphorin 3A is a secreted protein that regulates cell motility and attachment in axon guidance, vascular growth, immune cell regulation and tumor progression. However, nothing is known about its role in kidney pathophysiology. Here, we determined whether semaphorin3A is induced after acute kidney injury (AKI) and whether urinary semaphorin 3A(More)
BACKGROUND Effective interventions to increase physical activity levels are critical in a nation where inactivity is a national public health problem. OBJECTIVE This pilot study examined whether a minimal intervention (daily records of physical activity) increased activity levels in a community sample of working women. METHODS In a longitudinal,(More)
BACKGROUND Key factors in successful long-term exercise maintenance are not well understood. The Relapse Prevention Model (RPM) may provide a framework for this process. PURPOSE The purpose of this study was to examine the relationships among characteristics of exercise high-risk situations, components of the RPM relevant to exercise slips, and follow-up(More)
OBJECTIVE This study was performed to determine: 1) the rate and source of microbiologic contamination of photostimulable phosphor plates (PSP) in a predoctoral clinic; and 2) whether a combination of weekly gas sterilization and barrier protocols can prevent contamination of PSP plates. METHODS Fifty plates in clinical use and 25 gas-sterilized control(More)
INTRODUCTION Injection of sodium hypochlorite (NaOCl) from the root canal into periapical tissues may result in a NaOCl incident. The purpose of this study was to examine the fluid pressure generated by canal cleansing devices at the apical interface, when the tip of the irrigation device was not binding to the canal walls. METHODS Apical pressure was(More)
Immobilization of phosphoproteins on a collagen matrix is important for the induction of intrafibrillar apatite mineralization. Unlike phosphate esters, polyphosphonic acid has no reactive sites for covalent binding to collagen amine groups. Binding of poly(vinyl phosphonic acid) (PVPA), a biomimetic templating analog of matrix phosphoproteins, to collagen(More)
PROBLEM Little is known about the effectiveness of a comprehensive psychoeducational intervention on depression, self-esteem, and parenting attitudes/beliefs of at-risk pregnant and parenting adolescents. METHODS Adolescents (N = 41) attending either a residential treatment facility (RTF) or a rural alternative school (RAS) participated in a(More)
