Background: Although there is no absolute diagnostic test for periprosthetic infection, the synovial fluid leukocyte count and neutrophil percentage have been reported to high sensitivity specificity. However, cutoff values these tests are not agreed upon. We sought identify definite both that may help diagnose infection at site of a prosthetic joint. Methods: analyzed had aspirated preoperatively from 429 knees undergone revision arthroplasty three different academic institutions; 161 were...
Purpose To retrospectively compare image quality and radiation dose between a reduced-dose computed tomographic (CT) protocol that uses model-based iterative reconstruction (MBIR) standard-dose CT 30% adaptive statistical (ASIR) with filtered back projection. Materials Methods Institutional review board approval was obtained. Clinical images of the chest, abdomen, pelvis obtained were identified. Images reconstructed two algorithms: MBIR 100% ASIR. All subjects had undergone within prior...
Objectives To determine whether bowel wall fibrosis can be detected in freshly resected human intestinal specimens based on ultrasound‐derived shear wave speed. Methods Seventeen intact (>3‐cm) segments (15 small and 2 large intestine) from 12 patients with known or suspected inflammatory disease were procured immediately after surgical resection. Ultrasound elastography of the was performed by two methods (Virtual Touch Quantification [VTQ] Virtual Touch‐IQ [VT‐IQ]; Siemens Medical...

The purpose of this article is to evaluate single-source dual-energy CT (DECT) for distinguishing benign and indeterminate adrenal nodules, with attention the effects phase IV contrast enhancement.A retrospective review revealed 273 contrast-enhanced abdominal DECT examinations from November 2009 through March 2012. Fifty nodules 0.8 cm or larger were identified in 41 patients (22 women 19 men; average age, 66 years; age range, 36-88 years). postprocessing measurements independently...
Revision total hip arthroplasty in the very elderly is believed to be associated with a high complication rate. We evaluated early outcomes and prevalence of complications following revision patients older than eighty years age compared them those younger patient population.We retrospectively reviewed results 170 arthroplasties that had been performed 159 octogenarians our institute between 1992 1999. The mean at time surgery was 83.8 years, follow-up 6.8 years. then these arthroplasties,...
A leading HIV vaccine strategy requires a priming immunogen to induce broadly neutralizing antibody (bnAb) precursors, followed by series of heterologous boosters elicit somatic hypermutation (SHM) and produce bnAbs. In two randomized, open-label phase 1 human clinical trials, IAVI-G002 in the United States IAVI-G003 Rwanda South Africa, we evaluated safety immunogenicity mRNA-encoded nanoparticles as immunogens (both trials) first-boosting (IAVI-G002). The vaccines were generally safe well...
Ambulatory care visits for chronic sinusitis outnumber acute sinusitis. The majority of these are with non-otolaryngologists. In order to better understand patients diagnosed by non-otolaryngologists, we sought determine if incident cases primary (PC) or emergency medicine (EM) providers meet diagnostic criteria.This was a retrospective cohort study. Patients were identified using administrative data from 2005 2006. dataset then clinically annotated based on chart review. We excluded...
Objective Chronic low back pain (CLBP) is associated with fatigue, pain, poor sleep, and disability. Acupressure a low-risk treatment option used to manage symptoms in other groups, but its efficacy, particularly on fatigue unknown CLBP. This study examined preliminary effects of two types self-administered acupressure (relaxing stimulating) reported Methods A randomized pilot trial was conducted (N = 67) which participants were into six weeks relaxing acupressure, stimulating or usual care....
Objectives and Hypothesis Our objectives were to characterize the quality of acute sinusitis care identify nonclinical factors associated with antibiotic use for sinusitis. We hypothesized that we would provider‐level use. Study Design Retrospective cohort at a single academic institution. Methods developed clinically annotated an administrative dataset adult patients diagnosed between January 1, 2005, December 31, 2006. used receipt antibiotics. Results find 66.0% mild symptoms short...
OBJECTIVE. The purpose of this study was to determine whether diagnostic radiologists impart variation into resource use and patient outcomes in emergency department (ED) patients undergoing CT for headache. MATERIALS AND METHODS. This a single-institution retrospective quality assurance cohort 25,596 unique adult ED head headache from January 2012 October 2017. examinations were interpreted by 55 attending (25 neuroradiologists, 30 other specialties) who each mean 1469.8 ± 787.9...
Objective To compare the prevalence of acute sinusitis (AS) and chronic (CS) diagnosed by primary care emergency medicine physicians in our academic institution to national data. Study Design Cross-sectional pilot study institutional census data a population-based sample. The setting was departments at an healthcare community practices nationally. Materials Methods We determined proportion adults visits for AS CS from January 1, 2005, December 31, 2010. used same parameters with National...

Extending leg length in a biped entity may improve some gait factors such as speed, worsening others. This study is undertaken to better understand the kinetic and kinematic aspects of human following changes geometry lower extremities. An artificial structure built be attached fixed one's leg. Using two-sensor motion capture system practical walking data with extended collected for three different patterns, which parameters are calculated. Particularly, joints internal forces torques well...
Variances in perceived standards regarding research integrity appear to exist between China and the U.S. An established joint institute for translational clinical one Chinese health system provides a valuable venue which evaluate these perceptions better. We therefore undertook survey of 209 physicians at two institutions 2013–14. The vast majority from both understood necessity obtaining informed consent participants, need provide description risks participation, voluntary nature...
Herein, a navel stimuli-responsive magnetic graphene oxide/hyperbranched copolymer nanocomposites (GO@Fe3O4@HBC) was prepared via mixing surface-initiated RAFT and self-condensing vinyl polymerization technique. In the first step, chain transfer monomer (CTM) synthesized by esterification reaction between 2-(dodecylthiocarbonothioylthio)-2-methylpropionic acid (DDMAT) 2-Hydroxyethyl methacrylate (HEMA). Besides, oxide nanosheets were decorated with Fe3O4 nanoparticles. The surface of...
Abstract Background Obesity and diabetes as well their related complications result in both individual global health burdens. Among patients who present with obesity diabetes, bariatric surgery can lead to remission of these diseases. However, the possible impact on magnitude weight loss outcomes after has not been quantified. Methods To address this question, we extracted data from Michigan Bariatric Surgery Cohort (MI-BASiC) see whether at baseline could be a predictor outcomes....
