Gender, school and academic year differences among Spanish university students at high-risk for developing an eating disorder: An epidemiologic study

<p>Abstract</p> <p>Background</p> <p>The aim of this study was to assess the magnitude of the university population at high-risk of developing an eating disorder and the prevalence of unhealthy eating attitudes and behaviours amongst groups at risk; gender, school or academic year differences were also explored.</p> <p>Methods</p> <p>A cross-sectional study based on self-report was used to screen university students at high-risk for an eating disorder. The sample size was of 2551 university students enrolled in 13 schools between the ages of 18 and 26 years. The instruments included: a social-demographic questionnaire, the Eating Disorders Inventory (EDI), the Body Shape Questionnaire (BSQ), the Symptom Check List 90-R (SCL-90-R), and the Self-Esteem Scale (RSE). The sample design is a non-proportional stratified sample by academic year and school. The prevalence rate was estimated controlling academic year and school. Logistic regression analysis was used to investigate adjusted associations between gender, school and academic year.</p> <p>Results</p> <p>Female students presented unhealthy weight-control behaviours as dieting, laxatives use or self-induced vomiting to lose weight than males. A total of 6% of the females had a BMI of 17.5 or less or 2.5% had amenorrhea for 3 or more months. In contrast, a higher proportion of males (11.6%) reported binge eating behaviour. The prevalence rate of students at high-risk for an eating disorder was 14.9% (11.6–18) for males and 20.8% (18.7–22.8) for females, according to an overall cut-off point on the EDI questionnaire. Prevalence rates presented statistically significant differences by gender (p < 0.001) but not by school or academic year.</p> <p>Conclusion</p> <p>The prevalence of eating disorder risk in university students is high and is associated with unhealthy weight-control practices, similar results have been found in previous studies using cut-off points in questionnaires. These results may be taken into account to encourage early detection and a greater awareness for seeking treatment in order to improve the diagnosis, among students on university campuses.</p

A school-based program implemented by community providers previously trained for the prevention of eating and weight-related problems in secondary-school adolescents : the MABIC study protocol

Background: The prevention of eating disorders and disordered eating are increasingly recognized as public health priorities. Challenges in this field included moving from efficacy to effectiveness and developing an integrated approach to the prevention of a broad spectrum of eating and weight-related problems. A previous efficacy trial indicated that a universal disordered eating prevention program, based on the social cognitive model, media literacy educational approach and cognitive dissonance theory, reduced risk factors for disordered eating, but it is unclear whether this program has effects under more real-world conditions. The main aim of this effectiveness trial protocol is to test whether this program has effects when incorporating an integrated approach to prevention and when previously-trained community providers implement the intervention. Methods/design: The research design involved a multi-center non-randomized controlled trial with baseline, post and 1-year follow-up measures. Six schools from the city of Sabadell (close to Barcelona) participated in the intervention group, and eleven schools from four towns neighboring Sabadell participated in the control group. A total of 174 girls and 180 boys in the intervention group, and 484 girls and 490 boys in the control group were registered in class lists prior to baseline. A total of 18 community providers, secondary-school class tutors, nurses from the Catalan Government's Health and School Program, and health promotion technicians from Sabadell City Council were trained and delivered the program. Shared risk factors of eating and weight-related problems were assessed as main measures. Discussion: It will be vital for progress in disordered eating prevention to conduct effectiveness trials, which test whether interventions are effective when delivered by community providers under ecologically valid conditions, as opposed to tightly controlled research trials. The MABIC project will provide new contributions in this transition from efficacy to effectiveness and new data about progress in the integrated approach to prevention. Pending the results, the effectiveness trial meets the effectiveness standards set down by the Society for Prevention Research. This study will provide new evidence to improve and enhance disordered eating prevention programs

Regional and experiential differences in surgeon preference for the treatment of cervical facet injuries: a case study survey with the AO Spine Cervical Classification Validation Group

Purpose: The management of cervical facet dislocation injuries remains controversial. The main purpose of this investigation was to identify whether a surgeon’s geographic location or years in practice influences their preferred management of traumatic cervical facet dislocation injuries. Methods: A survey was sent to 272 AO Spine members across all geographic regions and with a variety of practice experience. The survey included clinical case scenarios of cervical facet dislocation injuries and asked responders to select preferences among various diagnostic and management options. Results: A total of 189 complete responses were received. Over 50% of responding surgeons in each region elected to initiate management of cervical facet dislocation injuries with an MRI, with 6 case exceptions. Overall, there was considerable agreement between American and European responders regarding management of these injuries, with only 3 cases exhibiting a significant difference. Additionally, results also exhibited considerable management agreement between those with ≤ 10 and &gt; 10&nbsp;years of practice experience, with only 2 case exceptions noted. Conclusion: More than half of responders, regardless of geographical location or practice experience, identified MRI as a screening imaging modality when managing cervical facet dislocation injuries, regardless of the status of the spinal cord and prior to any additional intervention. Additionally, a majority of surgeons would elect an anterior approach for the surgical management of these injuries. The study found overall agreement in management preferences of cervical facet dislocation injuries around the globe

Structure and inhibition of SARS-CoV-1 and SARS-CoV-2 main proteases by oral antiviral compound AG7404

Severe acute respiratory syndrome coronaviruses 1 and 2 (SARS-CoV-1 and SARS-CoV-2) pose a threat to global public health. The 3C-like main protease (Mpro), which presents structural similarity with the active site domain of enterovirus 3C protease, is one of the best-characterized drug targets of these viruses. Here we studied the antiviral activity of the orally bioavailable enterovirus protease inhibitor AG7404 against SARS-CoV-1 and SARS-CoV-2 from a structural, biochemical, and cellular perspective, comparing it with the related molecule rupintrivir (AG7800). Crystallographic structures of AG7404 in complex with SARS-CoV-1 Mpro and SARS-CoV-2 Mpro and of rupintrivir in complex with SARS-CoV-2 Mpro were solved, revealing that all protein residues interacting with the inhibitors are conserved between the two proteins. A detailed analysis of protein-inhibitor interactions indicates that AG7404 has a better fit to the active site of the target protease than rupintrivir. This observation was further confirmed by biochemical FRET assays showing IC50 values of 47 μM and 101 μM for AG7404 and rupintrivir, respectively, in the case of SARS-CoV-2 Mpro. Equivalent IC50 values for SARS-CoV-1 also revealed greater inhibitory capacity of AG7404, with a value of 29 μM vs. 66 μM for rupintrivir. Finally, the antiviral activity of the two inhibitors against SARS-CoV-2 was confirmed in a human cell culture model of SARS-CoV-2 infection, although rupintrivir showed a higher potency and selectivity index in this assay.This study was supported by the Ministry of Science and Innovation of Spain (grant numbers BFU2017-83720-P and PID-2020-120141GB-I00 to MC) and Spanish National Research Council (grant numbers 2020AEPP116 to MC and PIE-RD-COVID-19 ref.

Lipoprotein lipase expression in unmutated CLL patients is the consequence of a demethylation process induced by the microenvironment

We have previously demonstrated that lipoprotein lipase (LPL) is associated to an unmutated immunoglobulin profile and clinical poor outcome in Chronic Lymphocytic Leukemia (CLL). Despite the usefulness of LPL for CLL prognosis, its functional role and the molecular mechanism regulating its expression remain elusive. Since interaction of CLL B-cells with tissue microenvironment favors disease progression by promoting malignant B-cell growth and considering that tissue methylation can be altered by environmental factors, we investigated the methylation status of LPL gene and the possibility that its over-expression could be associated to microenvironment signals. By comparing methylation changes in the LPL-CpG island between unmutated and mutated CLL patients, we could demonstrate a clear association between LPL expression and a demethylation process in the CpG island near the promoter region of the LPL gene. This process can be induced by proliferative and specific stimuli,particularly we found that CLL B-cell activation through the CD40 plus IL-4 pathway led to LPL expression and gene demethylation in LPL negative CLL samples. Overall, these results suggest that an epigenetic mechanism, triggered by the microenvironment, regulates LPL expression in CLL cells.Fil: Moreno, P.. Instituto Pasteur de Montevideo; Uruguay.
