Obesity and Disparities in Human Papillomavirus Vaccination for U.S. Adolescent Girls and Young Women

Background

Obesity is recognized as a barrier to receiving women's preventive health services, including cervical and breast cancer screening. Little is known about whether obesity is associated with a lower incidence of human papillomavirus (HPV) vaccination, another important preventive care service for adolescent girls and young women. The objective of this study was to determine if adolescent girls and young women with obesity are less likely to receive HPV vaccination compared with individuals with normal weight.

Nonlinear behavior of certain optic nerve head parameters and their determinants in normal subjects

OBJECTIVE: To investigate the relationship between the absolute area of certain optic disc parameters and a number of ocular dimensional characteristics and demographic factors in young, healthy subjects. DESIGN: Cross-sectional study. PARTICIPANTS: One hundred twenty-one subjects, aged 16.5 to 35.4 years participated, encompassing a wide range of refractive error from +4 diopters (D) to -25.75 D. One eye from each subject was randomly selected for examination. MAIN OUTCOME MEASURES: Absolute size of the optic disc parameters: optic disc area (DA), neuroretinal rim area (NRA), optic cup area (CA), and peripapillary atrophy area (PA). METHODS: Absolute sizes of optic disc parameters were determined from digitized photographic color transparencies, taking into consideration the magnification of the fundus camera and human eye. Relationships between the absolute size of the optic disc features and axial length, crystalline lens thickness, anterior chamber depth, ocular refraction, front surface keratometry, age, and gender were examined. RESULTS: Axial length, lens thickness, front surface keratometry, and age demonstrated positive associations with all optic disc parameters, and anterior chamber depth and ocular refraction demonstrated negative associations in all cases. Multiple regression analysis revealed that the associations observed univariately for age, anterior chamber depth, lens thickness, front surface keratometry, and ocular refraction were confounded by axial length for all disc parameters. After taking logs, DA and NRA exhibit an exponential relationship with axial length, whereas PA and CA exhibit a linear relationship with axial length. DA and NRA increase by approximately 3% per millimeter increase in axial length at 20 mm and up to 40% for DA and 50% for NRA at an axial length of 35 mm. PA and CA are estimated to increase by 26% (10%-44%) and 10% (5%-16%), respectively, per millimeter increase in axial length. Females have approximately 5% smaller DA and 7% smaller NRA than males, but these effects are not statistically significant (P > 0.2). From the multiple regression analysis, females have 31% larger optic cup areas (1%-57%, P = 0.03) and 24% smaller PA (42% smaller to 5% larger P = 0.06) than males, but these effects are of borderline statistical significance at 5%. CONCLUSIONS: Of the ocular biometric factors considered, axial length seems to be the most important predictor of the absolute area of the optic disc parameters. No association exists between any disc parameter and age in this sample of subjects less than 40 years of age. Females exhibited smaller values for DA, NRA, and PA than did males, differences that were not statistically significant, and larger CA (P = 0.03).     

Cognitive and Motor Recovery and Predictors of Long-Term Outcome in Patients With Traumatic Brain Injury

ObjectivesTo explore the patterns of cognitive and motor recovery at 4 time points from admission to 9 months after discharge from inpatient rehabilitation (IR) and to investigate the association of therapeutic factors and conditions before and after discharge with long-term outcomes.DesignSecondary analysis of traumatic brain injury (TBI) and practice-based evidence dataset.SettingIR in Ontario, Canada.ParticipantsPatients with TBI consecutively admitted for IR between 2008 and 2011 who had data available from admission to 9 months after discharge (N=85).InterventionsNot applicable.Main Outcome MeasureFIM-Rasch cognitive and motor scores at admission, discharge, 3 months after discharge, and 9 months after discharge.ResultsCognitive and motor recovery showed similar patterns of improvement with recovery up to 3 months but no significant change from 3 to 9 months. Having fewer postdischarge health conditions was associated with better long-term cognitive scores (95% confidence interval, -13.06 to -1.2) and added 9.9% to the explanatory power of the model. More therapy time in complex occupational therapy activities (95% confidence interval, .02 to .09) and fewer postdischarge health conditions (95% confidence interval, -19.5 to -3.8) were significant predictors of better long-term motor function and added 14.3% and 7.2% to the explanatory power of the model, respectively.ConclusionResults of this study inform health care providers about the influence of the timing of IR on cognitive and motor recovery. In addition, it underlines the importance of making patients and families aware of residual health conditions following discharge from IR.     

Spinal Manipulation Therapy Improves Tactile Allodynia and Peripheral Nerve Functionality and Modulates Blood Oxidative Stress Markers in Rats Exposed to Knee-Joint Immobilization

ObjectiveThe purpose of our study was to evaluate the effect of manually assisted lumbar spinal manipulation therapy on tactile allodynia, peripheral nerve functional recovery, and oxidative markers in rats exposed to knee immobilization-inducing hypersensitivity.MethodsTactile allodynia and sciatic, tibial, and peroneal functional indices were assessed before the knee joint immobilization, 24 hours after the knee cast removal, and 24 hours after 3 weeks of lumbar therapy with the Activator Adjusting Instrument, model 4 (AAI 4). Subsequently, the blood was collected from each rat, and oxidative markers such as lipid hydroperoxide levels; nitric oxide metabolites; and superoxide dismutase, catalase, and glutathione peroxidase activities were assessed.ResultsThe AAI 4 improved the immobilization-induced allodynia and recovered the peripheral nerve functional indices impaired after knee immobilization. Immobilized rats treated with AAI 4 therapy presented a lack of significant changes in lipid hydroperoxides and nitric oxide metabolites in the plasma contrasting with rats that were kept freely in their cages, with no therapy applied, which presented elevated lipid hydroperoxides levels. Also, the antioxidant catalase enzymatic activity decreased in the blood of rats immobilized and treated with AAI 4.ConclusionThese results suggest that manually assisted lumbar spinal manipulation therapy modulates systemic oxidative stress, which possibly contributes to the analgesia and recovery of peripheral nerve functionality.
