OBJECTIVE To estimate differences in the length of stay (LOS) and costs for comparable pediatric patients with and without venous thromboembolism (VTE), catheter-associated urinary tract infection (CAUTI), and pressure ulcer (PU). METHODS We identified at-risk children 1 to 17 years old with inpatient discharges in the Nationwide Inpatient Sample. We used a high dimensional propensity score m...

OBJECTIVE To determine frequency, obstetrical risk factors and the subsequent feto-maternal outcome in women suffering from placental abruption. METHODS A retrospective case series study was carried out in the Department of Obstetrics and Gynaecology Unit One, Liaquat University Hospital Hyderabad, Pakistan from 1st January 2006 to 31st December 2006. All women with the diagnosis of placental...

Objective Previous studies, although inconclusive, have suggested possible associations of environmental risk factors with the development of giant cell arteritis (GCA). We aim to investigate seasonal influence on the incidence of GCA across Australia and New Zealand. Methods In establishing an international study to investigate the molecular aetiology of GCA, archived temporal artery biopsy ...

BACKGROUND This study aims to examine the impact of women's characteristics (demographics, risk behaviour, and beliefs) on the uptake of cervical cancer screening, taking practice characteristics (demographic and organizational) into account. METHODS Routinely collected data of screening status were sampled from electronic medical records of 32 Dutch general practices. Additionally, a questio...

TO THE EDITOR—We have read with interest the patient-level quantitative review of randomized trials for the treatment of invasive candidiasis by Andes et al [1]. However, we do have some questions regarding the figures of included patients. Andes et al report that all modified intent-to-treat (MITT) patients of the 7 analyzed trials were included. Excluded from analysis were cases with missing ...

This paper explores the influence of online political advertising in the form of digital videos posted on YouTube. We focus on the various campaigns for U.S. Senate in 2010. Using data on the content of online ads, television spots, survey data and coding of media coverage, we examine several indirect measure of YouTube‘s influence on election outcomes. Our findings indicate that online adverti...

The 1993 Survey of Recent Mothers was a statewide postal survey of 2224 women who gave birth in Victoria in 2 weeks in 1993, excepting those who had a stillbirth or whose baby was known to have died. The survey questionnaire was mailed to women 6-7 months after the birth. The response rate, excluding duplicate responses, one woman who had a stillbirth and those whose questionnaires were returne...

Non-static gravitational fields generally introduce frequency shifts when bending light. In this paper, I discuss the frequency shifts induced in the bending of light by moving masses. As examples, I treat the recently discovered high-velocity pulsar PSR 2224+65 and a typical Einstein ring. PACS Numbers: 97.60Gb, 97.60Jd The four Jupiter probes Pioneers 10, 11 and Voyagers 1,2 have all reached ...

The FIRST LEGO League (FLL) organizes friendly competitions between students, ages 9to 14-years-old. The competition focuses on engineering challenges addressing a theme in science and technology. For 2006, FLL chose nanotechnology as the central theme. The youth used a semi-autonomous robot constructed from LEGO ® brand building blocks to perform tasks related to current themes in nanotechnolo...

Predictions of the flow over a wall-mounted hump are obtained using solutions of the Reynolds-averaged Navier-Stokes (RANS) equations and Detached-Eddy Simulation (DES). The upstream solution is characterized by a two-dimensional turbulent boundary layer with a thickness approximately half of the maximum hump thickness measured at a location about two chord lengths upstream of the leading edge....
