OBJECTIVES An unlinked anonymous seroprevalence study was conducted to estimate the prevalence of hepatitis C virus (HCV) infection in samples derived from antenatal clinic attendees at 2 East London Hospitals. An unexpectedly high HCV seroprevalence of 2.6% (1.2% viraemic) had been revealed during an unlinked study of the emergency department at 1 of these hospitals. DESIGN 1000 stored resid...

Background and Aim: Renal cell carcinoma (RCC) is the 13th most common cancer worldwide and accounts for 4% of all adult malignancies. Herein the state of the art and recent advances in cross-sectional radiological imaging applied to RCC are reviewed, including ultrasonography, computed tomography, magnetic resonance imaging, and positron emission tomography. Methods: Literature search of peer-...

Objective. The aim of this post hoc analysis was to establish the relationship between FENO levels and the asthma predictive index (API) among infants with recurrent wheezing.Methods. Infants with recurrent wheezing (three or more episodes) were recruited consecutively and online FENO tests at tidal breathing withmultiple breaths were performed.Results. Twenty-seven (84%) out of 32 infants (med...

BACKGROUND AND OBJECTIVE Creatine deficiency may play a role in the neurobiology of autism and may represent a treatable cause of autism. The goal of the study was to ascertain the prevalence of creatine deficiency syndromes (CDSs) in children with autism spectrum disorder (ASD). METHODS In a prospective multicenter study, 443 children were investigated after a confirmed diagnosis of ASD. Ran...

BACKGROUND Recently, several studies have reported age-associated increases in muscle coactivation during postural control. A rigid posture induced by strong muscle coactivation reduces the degree of freedom to be organized by the postural control system. The purpose of this study was to clarify the effect of balance training on muscle coactivation during postural control in older adults. MET...

RATIONALE AND OBJECTIVES The purpose of this study was to assess the effect of unilateral common iliac vein occlusion on the capturing efficacy of the Greenfield filter in vitro. MATERIALS AND METHODS A stainless steel over-the-wire Greenfield filter was placed in the Silastic inferior vena cava module of a pulsatile circuit. Three 30-mm blood clots in sets of five were injected through the m...

In light of recent observations of spectra of the quasars SDSS 1030+0524 (Becker et al. 2001) and SDSS 1044-0125 (Djorgovski et al. 2001), we study the observational signatures of different stages of the reionization epoch. During the initial, pre-overlap stage, the hydrogen throughout the universe is neutral except for isolated H II bubbles due to individual ionizing sources. The central stage...
