OBJECTIVE The goal of this study was to analyze the value an adult spinal deformity frailty index (ASD-FI) in preoperative risk stratification. Preoperative assessment is imperative before procedures known have high complication rates, such as ASD surgery. Frailty has been associated with complications trauma surgery, and assessments could improve accuracy stratification by providing a comprehensive analysis patient factors that contribute increased complications. METHODS Using 40 variables,...
Resistance to conventional antibiotics is a growing public health concern that quickly outpacing the development of new antibiotics. This has led Infectious Diseases Society America (IDSA) designate
OBJECTIVE The aim of this study was to investigate the incidence and factors associated with complications following idiopathic scoliosis surgery in adolescents. METHODS Nationwide Inpatient Sample database used identify patients 10-18 years age who had undergone spinal fusion for adolescent (AIS) from 2002 2011. Twenty-three unique in-hospital postoperative complications, including death, were examined. A series logistic regressions determine if any demographic, comorbid, or surgical...
Despite the worldwide popularity of running as a sport for children, relatively little is known about its impact on injury and illness. Available studies have focused adolescent athletes, but these findings may not be applicable to preadolescent pubescent athletes. To date, there are no evidence or consensus-based guidelines identifying risk factors illness in youth runners, current recommendations regarding suitable distances runners at different ages opinion based. The International...
Study Design. Analysis of a prospective multicenter database. Objective. To assess the ability recently created Adult Spinal Deformity (ASD) Frailty Index (ASD-FI) to predict odds major complications and length hospital stay for patients who had more severe preoperative deformity underwent invasive ASD surgery compared with in database used create index. Summary Background Data. Accurate estimates risk are necessary given high complication rates currently associated surgery. Methods....
The rapid academic and industrial development of nanotechnology has led to its implementation in laboratory teaching for undergraduate-level chemistry engineering students. This experiment introduces the galvanic replacement reaction synthesis hollow metal nanoparticles investigates optical properties these nanoparticles. Changes localized surface plasmon resonance from solid are monitored by UV–vis spectroscopy, while corresponding morphological changes validated transmission electron...
A double-blind controlled trial of aqueous vasopressin injection (Pitressin) in the prophylaxis lumbar puncture reactions 50 patients showed that incidence was unaffected, but severe occurred less frequently treatment group. Moderately side-effects 27% those receiving vasopressin.
Study Design. A retrospective review of a prospectively collected database, the Nationwide Inpatient Sample (NIS), years 2003 to 2012. Objectives. The aim this study was examine trends in management scoliosis elderly (age >75 yrs) patients from Summary Background Data. Scoliosis incidence rises with increasing age, and age has been shown be an independent risk factor for surgical complications surgery. Previous studies have displayed frequency on scoliotic last decade, but not investigated...
Sugar intake, particularly fructose, is implicated as a factor contributing to insulin resistance via hepatic de novo lipogenesis (DNL). A nine-day fructose reduction trial, controlling for other dietary factors and weight, in children with obesity metabolic syndrome, decreased DNL mitigated cardiometabolic risk (CMR) biomarkers. Ceramides are bioactive sphingolipids whose dysregulated metabolism contribute lipotoxicity, resistance, CMR. We evaluated the effect of on ceramides correlations...
Cervical alignment has become increasingly important in the planning of spine surgery. A relationship between slope T1 (T1S), cervical lordosis (CL), and overall sagittal vertical axis (cSVA) previously been demonstrated, but exact nature this is poorly understood. In study, we derive theoretical empirical equations to better understand how T1S CL affect cSVA. The first equation was developed on a basis using inherent trigonometric relationships spine. By treating as arc circumference, by...
Objectives We evaluated the effect of a nutrition education intervention on bone stress injury (BSI) incidence among female distance runners at two NCAA Division I institutions. Methods Historical BSI rates were measured retrospectively (2010–2013); then followed prospectively in pilot (2013–2016) and (2016–2020) phases. The primary aim was to compare historical Pilot phase data are included only for descriptive purposes. comprised team presentations focused optimising energy availability...
Objective: Athletes who engage in repetitive upper-extremity exercise are susceptible to neurogenic thoracic outlet syndrome (nTOS). We sought identify typical presenting symptoms and common findings on diagnostic workup, addition evaluating rates of return play following various treatment interventions. Design: Retrospective chart review. Setting: Single institution. Participants: Medical records Division 1 athletes containing the diagnosis nTOS between years 2000 2020 were identified. with...
Obesity is a major and growing health concern associated with risk of falls. While obese individuals exhibit increased sway during quiet standing, most falls result from some type postural perturbation. This study investigated effects obesity on balance recovery small forward perturbations. Altogether, 20 males, 10 normal weight (BMI: 21.9 ± 1.4) 33.2 2.3), received force (pendulum) position (release static lean angle) Obese showed less centre mass (COM) displacements slower COM velocities...
Purpose: To demonstrate delivery of Au nanocages to cells using the galectin-1 binding peptide anginex (Ax) and value this targeting for selective in vitro photothermal cell killing.Materials methods: were synthesised, coated with polydopamine (PDA), conjugated Ax. Tumour endothelial viability was measured without laser irradiation. Photoacoustic (PA) mapping PA flow cytometry used confirm tissue slices ex vivo.Results: Cell maintained at ≥50% 100 pM suggesting low toxicity nanocage alone....
