Pelvic Tilt Disparities and Lower Extremity Strength and Mobility Differences in Collegiate Wrestlers
ABSTRACT
The presence of excessive anterior pelvic tilt (PT) prior to performing loaded structural movements such as a squat or deadlift may be detrimental. However the ability to move from a neutral spine into a slight anterior PT during these movements may be beneficial for postural control, but this capability and relationship to hip function is under-represented in the literature. PURPOSE: The purpose of this study was to determine the relationship between the ability to move into an anterior PT, hip and hamstring range of motion (ROM), hip strength, and y-balance test (YBT) scores in Division I wrestlers. METHODS: Twenty-two collegiate wrestlers completed a PT test, YBT, hip and hamstring ROM, and hip strength tests during pre-season after clearance by the team physician. Wrestlers were divided into: 1) those that could perform an anterior PT without compensation (PT-N; n = 11; age 19.7 ± 1.6 y; height: 175.3 ± 8.4 cm; mass: 79.4 ± 26.1 kg), and 2) those showing mobility or stability concerns during the PT test (PT-C; n = 11; age 19.6 ± 1.7 y; height: 176.5 ± 4.6 cm; mass: 73.8 ± 10.4 kg). Total hip ROM on the right (R) and left (L) was measured by summing internal and external rotation measured using a goniometer. Hip adduction and abduction strength was measured using a dynamometer, and calculated relative to body weight. The standardized YBT approach included measures of leg length to determine a composite score for both legs. Hamstring ROM was measured using the sit-and-reach test (SRT). Data were recorded using mean ± standard deviations. RESULTS: PT-N had higher total ROM than PT-C in the R hip (78.2 ± 11.1o vs 74.1 ± 8.8 o), L hip (72.9 ± 10.8 o vs 71.5 ± 8.8o), and SRT scores (39.4 ± 4.3 cm vs 33.5 ± 8.3 cm). PT-N had greater relative strength than PT-C for R hip adduction (44.6 ± 10.5 vs 40.7 ± 11.1 kg), L hip adduction (42.5 ± 9.7 vs 39.1 ± 11.8 kg), and L hip abduction (40.3 ± 14.3 vs 36.0 ± 6.8 kg), however these differences were muted relative to body weight. PT-N had higher composite YBT scores on the R leg (95.2 ± 8.5 vs 92.4 ± 4.8 %) and L leg (97.1 ± 9.1 vs 90.9 ± 4.4 %). CONCLUSION: In collegiate wrestlers sufficient hip mobility, motor control, and hip symmetry may be related to optimal postural control at the hip when flexing under heavy load. Further research with a larger sample size and baseline measures of PT is recommended to examine these trends in more detail
Condom-use Skills Checklist: A Proxy for Assessing Condom-use Knowledge and Skills When Direct Observation Is Not Possible
Because of the continued importance of correct condom-use in controlling the HIV epidemic and the limited availability of tools for assessing correct condom-use, methods for assessing condom-application skills, especially when direct observation is not feasible, are needed. Accordingly, in the context of a high-risk population (The Bahamas) for HIV, a 17-item scale—the Condom-use Skills Checklist (CUSC)—was developed for use among young adolescents and adults. The rationale and approach to developing the scale and some measures of internal consistency, construct validity, and criterion-related validity have been described. It is concluded that the scale offers a reasonable alternative to direct observation among older subjects and that further development may make it more useful among pre-adolescents

Passive Prophylactic Administration with a Single Dose of Anti-Fel d 1 Monoclonal Antibodies REGN1908-1909 in Cat Allergen-Induced Allergic Rhinitis: A Randomized, Double-blind, Placebo Controlled Trial
RATIONALE: Sensitization to Felis domesticus allergen 1 (Fel d 1) contributes to persistent allergic rhinitis and asthma. Existing treatment options for cat allergy, including allergen immunotherapy (AIT) are only moderately effective, and AIT has limited use due to safety concerns. OBJECTIVES: To explore the relationship among the pharmaokinteic, clinical, and immunological effects of REGN1908-1909 (anti-Fel d 1 monoclonal antibodies) in patients after treatment. METHODS: Patients received REGN1908-1909 (n=36) or placebo (n=37) in a phase 1b study. Fel d 1-induced basophil and IgE-facilitated allergen binding responses were evaluated at baseline and days 8, 29 and 85. Cytokine and chemokine levels in nasal fluids were measured. REGN1908-1909 inhibition of allergen-IgE binding in patient serum was evaluated. MEASUREMENTS AND MAIN RESULTS: Peak serum drug concentrations were concordant with maximal observed clinical response. The anti-Fel d 1 IgE/cat-dander IgE ratio in pretreatment serum correlated with Total Nasal Symptom Score improvement. The allergen neutralizing capacity of REGN1908-1909 was observed in serum and nasal fluid, and was detected in an inhibition assay. Type-2 cytokines (IL-4, IL-5 and IL-13) and chemokines (CCL17/TARC, CCL5/RANTES) in nasal fluid were inhibited in REGN1908-1909-treated patients compared to placebo (all P < 0.05); IL-13 and IL-5 levels correlated with TNSS improvement. Ex vivo assays demonstrated that REGN1908 and REGN1909 combined was more potent than each alone for inhibiting FcεRI- and FcεRII (CD23)-mediated allergic responses and subsequent T-cell activation. CONCLUSION: Single passive dose administration of Fel d 1-neutralizing IgG antibodies improved nasal symptoms in cat-allergic patients, and was underscored by suppression of FcεRI-, FcεRII- and Th2-mediated allergic responses.

Ovarian Cancer Epidemiology, Healthcare Access and Disparities (ORCHiD): Methodology for a Population-Based Study of Black, Hispanic and White Patients with Ovarian Cancer
INTRODUCTION: Less than 40% of patients with ovarian cancer (OC) in the USA receive stage-appropriate guideline-adherent surgery and chemotherapy. Black patients with cancer report greater depression, pain and fatigue than white patients. Lack of access to healthcare likely contributes to low treatment rates and racial differences in outcomes. The Ovarian Cancer Epidemiology, Healthcare Access and Disparities study aims to characterise healthcare access (HCA) across five specific dimensions-Availability, Affordability, Accessibility, Accommodation and Acceptability-among black, Hispanic and white patients with OC, evaluate the impact of HCA on quality of treatment, supportive care and survival, and explore biological mechanisms that may contribute to OC disparities.
METHODS AND ANALYSIS: We will use the Surveillance Epidemiology and Ends Results dataset linked with Medicare claims data from 9744 patients with OC ages 65 years and older. We will recruit 1641 patients with OC (413 black, 299 Hispanic and 929 white) from cancer registries in nine US states. We will examine HCA dimensions in relation to three main outcomes: (1) receipt of quality, guideline adherent initial treatment and supportive care, (2) quality of life based on patient-reported outcomes and (3) survival. We will obtain saliva and vaginal microbiome samples to examine prognostic biomarkers. We will use hierarchical regression models to estimate the impact of HCA dimensions across patient, neighbourhood, provider and hospital levels, with random effects to account for clustering. Multilevel structural equation models will estimate the total, direct and indirect effects of race on treatment mediated through HCA dimensions.
ETHICS AND DISSEMINATION: Result dissemination will occur through presentations at national meetings and in collaboration with collaborators, community partners and colleagues across othercancer centres. We will disclose findings to key stakeholders, including scientists, providers and community members. This study has been approved by the Duke Institutional Review Board (Pro00101872). Safety considerations include protection of patient privacy. All disseminated data will be deidentified and summarised

The interaction studied via femtoscopy in p + Nb reactions at
We report on the first measurement of and correlations via
the femtoscopy method in p+Nb reactions at , studied with the High Acceptance Di-Electron Spectrometer
(HADES). By comparing the experimental correlation function to model
calculations, a source size for pairs of and a slightly
smaller value for of is extracted.
Using the geometrical extent of the particle emitting region, determined
experimentally with correlations as reference together with a source
function from a transport model, it is possible to study different sets of
scattering parameters. The correlation is proven sensitive to
predicted scattering length values from chiral effective field theory. We
demonstrate that the femtoscopy technique can be used as valid alternative to
the analysis of scattering data to study the hyperon-nucleon interaction.Comment: 12 pages, 11 figure

Measurements of inclusive spectra and mean multiplicities of ,
K, p and produced in inelastic p+p interactions at
incident projectile momenta of 20, 31, 40, 80 and 158 GeV/c ( 6.3,
7.7, 8.8, 12.3 and 17.3 GeV, respectively) were performed at the CERN Super
Proton Synchrotron using the large acceptance NA61/SHINE hadron spectrometer.
Spectra are presented as function of rapidity and transverse momentum and are
compared to predictions of current models. The measurements serve as the
