The effectiveness of scoliosis screening programs: methods for systematic review and expert panel recommendations formulation

Background: Literature on scoliosis screening is vast, however because of the observational nature of available data and methodological flaws, data interpretation is often complex, leading to incomplete and sometimes, somewhat misleading conclusions. The need to propose a set of methods for critical appraisal of the literature about scoliosis screening, a comprehensive summary and rating of the available evidence appeared essential. METHODS: To address these gaps, the study aims were: i) To propose a framework for the assessment of published studies on scoliosis screening effectiveness; ii) To suggest specific questions to be answered on screening effectiveness instead of trying to reach a global position for or against the programs; iii) To contextualize the knowledge through expert panel consultation and meaningful recommendations. The general methodological approach proceeds through the following steps: Elaboration of the conceptual framework; Formulation of the review questions; Identification of the criteria for the review; Selection of the studies; Critical assessment of the studies; Results synthesis; Formulation and grading of recommendations in response to the questions. This plan follows at best GRADE Group (Grades of Recommendation, Assessment, Development and Evaluation) requirements for systematic reviews, assessing quality of evidence and grading the strength of recommendations. CONCLUSIONS: In this article, the methods developed in support of this work are presented since they may be of some interest for similar reviews in scoliosis and orthopaedic fields.

Stress parental et lien mère-enfant: impact sur le développement de l’enfant âgé d’un an.

Au cours de la grossesse et dans les premières années de vie de l’enfant, plusieurs facteurs externes, tels que le stress maternel ou le lien maternel, peuvent interférer avec son développement et avoir des conséquences à court et à long terme. Bien que le stress maternel périnatal ait souvent été étudié, plusieurs facteurs pré et postnataux potentiellement confondants (comme le stress paternel, la dépression, la prise d’antidépresseurs, etc.) n’ont pas systématiquement été pris en compte. Comparativement à l’attachement de l’enfant (à sa mère), moins de recherches se sont intéressées au lien maternel, en particulier chez des femmes ayant un diagnostic de dépression et/ou d’anxiété et exposées à des antidépresseurs. Notre thèse visait donc à étudier ces deux facteurs et leur association avec le développement du jeune enfant âgé d’un an, dans un contexte où la santé mentale maternelle (présence ou non de troubles psychologiques) et de traitements pharmacologiques associés étaient aussi considérés. Afin d’améliorer le dépistage de retards développementaux, nous avons également évalué l’administration au téléphone de deux instruments de pré-dépistage et dépistage actuellement utilisés. Notre thèse était constituée de quatre phases dont les objectifs étaient: la détermination des propriétés psychométriques de l’échelle de stress perçu de quatre items (en français et en anglais) au sein de la population de femmes enceintes (première étude); évaluer l’effet du stress maternel prénatal et parental postnatal sur le développement de l’enfant âgé d’un an (deuxième étude); estimer l’association entre le lien maternel et le développement de l’enfant âgé d’un an, en stratifiant sur la prise maternelle d’antidépresseurs (troisième étude); et évaluer l’administration au téléphone du ″Ages and Stages Questionnaire″ (ASQ, version de 12 mois) et du ″Revised Pre-screening Denver Questionnaire″(R-PDQ, version de 9-24 mois),deux questionnaires utilisés pour le pré-dépistage et le dépistage du développement infantile (quatrième étude). Ce projet faisait partie d’une plus grande étude, nommée le projet OTIS (The″Organization of Teratology Information Specialists″ Antidepressant in Pregnancy cohort study), qui visait à évaluer l’impact de l’arrêt versus la continuation de la prise d’antidépresseurs au cours de la grossesse sur les comportements maternels et sur le développement de l’enfant âgé de un à trois ans. Ainsi, entre 2006 et 2010, la cohorte prospective OTIS de femmes enceintes a été construite et suivie jusqu’à trois ans postpartum. À partir de 2008, l’évaluation du stress et du lien maternel (thématiques de ce projet de thèse) a été incorporée au projet initial. Aussi, à partir de là, toute femme nouvellement recrutée pour la cohorte OTIS pouvait faire partie des études de cette thèse. Notre population source était composée des femmes enceintes ayant eu recours à un service nord-américain d’information sur les tératogènes ou ayant été suivies à la clinique d'obstétrique et de gynécologie du CHU Ste Justine. Pour être admissibles, les femmes devaient 1) être âgées d’au moins 18 ans, 2) être enceinte d’au maximum 14 semaines (le début de la grossesse étant défini comme étant le premier jour des dernières règles); 3) être exposées à un antidépresseur depuis au moins le premier jour de grossesse (pour le groupe exposé à un antidépresseur), 4) savoir lire et comprendre l’anglais ou le français. Pour les études deux, trois et quatre, les femmes devaient habiter dans un rayon de 250 km autour de Montréal pour recevoir notre visite à domicile, nécessaire à l’évaluation psychométrique du développement infantile. Les pères des enfants ont été recrutés à deux mois postpartum pour évaluer leur stress. Les données ont été collectées par entrevue téléphonique, auto-administration de questionnaires, et évaluation psychométrique du développement infantile. Dans le cadre de cette thèse, les femmes étaient suivies depuis le premier trimestre de grossesse jusqu’à un an postpartum. Les résultats de nos travaux démontrent que le recours à l’échelle de stress perçu de quatre items est une mesure fiable et valide pour mesurer le stress au cours de la grossesse (en recherche ou en clinique). Ensuite, le stress postnatal maternel et paternel serait défavorable au développement moteur et socio-émotionnel de l’enfant d’un an, respectivement. Par contre le stress maternel prénatal favoriserait le développement moteur. Un lien maternel optimal est associé à un meilleur développement socio-émotionnel à un an chez l’enfant, en particulier pour les femmes exposées à des antidépresseurs. Enfin, l’administration au téléphone de l’ASQ et des sous-échelles de langage, de motricité fine et motricité globale du R-PDQ serait une alternative possible au mode auto-administré pour dépister et pré-dépister les retards de développement chez les enfants.

Why us? Perceived injustice is associated with more sexual and psychological distress in couples coping with genito-pelvic pain.

Introduction Provoked vestibulodynia (PVD) is the most frequent cause of genito-pelvic pain/penetration disorder (GPPPD) and is associated with negative psychological and sexual consequences for affected women and their partners. PVD is often misdiagnosed or ignored and many couples may experience a sense of injustice, due to the loss of their ability to have a normal sexual life. Perceiving injustice has been documented to have important consequences in individuals with chronic pain. However, no quantitative research has investigated the experience of injustice in this population. Aim The aim of this study was to investigate the associations between perceived injustice and pain, sexual satisfaction, sexual distress, and depression among women with PVD and their partners. Methods Women diagnosed with PVD (N = 50) and their partners completed questionnaires of perceived injustice, pain, sexual satisfaction, sexual distress, and depression. Main Outcome Measures (1) Global Measure of Sexual Satisfaction Scale; (2) Female Sexual Distress Scale; (3) Beck Depression Inventory-II; and (4) McGill-Melzack Pain Questionnaire. Results After controlling for partners' age, women's higher level of perceived injustice was associated with their own greater sexual distress, and the same pattern was found for partners. Women's higher level of perceived injustice was associated with their own greater depression, and the same pattern was found for partners. Women's higher perceived injustice was not associated with their own lower sexual satisfaction but partners' higher perceived injustice was associated with their own lower sexual satisfaction. Perceived injustice was not associated with women's pain intensity. Conclusion Results suggest that perceiving injustice may have negative consequences for the couple's sexual and psychological outcomes. However, the effects of perceived injustice appear to be intra-individual. Targeting perceived injustice could enhance the efficacy of psychological interventions for women with PVD and their partners.

The purpose of the study, a sample of 150 entrepreneur-managers of SS1 units spread over Ernakulam district was surveyed through a specially designed questionnaire.

A study on the Effect of Psychological Empowerment on Job Satisfaction and Job Related Stress Among the Bank Employees

The present research is carried out to understand how psychological empowerment, job satisfaction and job related stress are related.In banking sector, employees are less satisfied and less motivated than employees in other lines of work (Kelley, 1990; Bajpai, Naval and Deepak, 2004). The banking industry also suffers from high employee turnover rate (Branham, 2005; Nelson, 2007) and high level of stress (Chen and Lien, 2008). There are no adequate studies linking psychological empowerment and job satisfaction, stress, turnover etc. among employees of banking sector. Lack of psychological empowerment could be a reason for these problems faced by banking sector. Further majority of studies in psychological empowerment are carried out in manufacturing sector and studies in service sector are concentrated on hotel industry and hospitals. Empowerment takes different forms in different contexts (Zimmerman, 1995). In the light of above discussion, the present research is directed to explore the dimensions of psychological empowerment of employees in banking sector and to find out whether high psychological empowerment can increase job satisfaction and reduce job related stress among employees in banking sector

In vivo screening of mangrove plants for anti WSSV activity in Penaeus monodon, and evaluation of Ceriops tagal as a potential source of antiviral molecules

The objective of the study was to find out a natural way to fight white spot syndrome virus (WSSV) in cultured shrimps, as the present scenario necessitated an organic remedy for the devastating pathogen in crustaceans. Under this research programme seven mangrove plants were collected, identified and aqueous extracts screened for their protective effect on the giant tiger shrimp Penaeus monodon against WSSV. The experimental design consisted two modes of application, such as exposure of the virus to the extract and injection challenge, and oral administration of the extract coated feed followed by oral challenge. All experimental animals were monitored through a nested diagnostic PCR analysis. Of the seven mangrove extracts screened aqueous extract from Ceriops tagal imparted total protection to shrimp from WSSV when challenged by both methods. Shrimps administered with the aqueous extract from C. tagal were devoid of virions. The HPLC fingerprint of the aqueous extracts from C. tagal showed more than 25 peaks and 7 of them were larger and well separated. Preliminary phytochemical analysis revealed the presence of alkaloids, flavonoids, polyphenolics, cardiac glycosides, saponins and sterols. The study indicated suitability of the aqueous extract of C. tagal as a possible prophylaxis for WSSV infection in shrimp. This is the first report on the anti WSSV property of the mangrove plant C. tagal

A study on the Effect of Psychological Empowerment on Job Satisfaction and Job Related Stress Among the Bank Employees

This study focuses on psychological empowerment of employees in banking sector because of the reasons stated below: Firstly, very little research has been conducted in understanding empowerment as a psychological construct. Majority of the studies have been conducted on the various empowerment practices in the organizations. Secondly, there is no empirical evidence that the empowerment practice will create a subjective feeling of empowerment within the individual. Employee empowerment will be effective only if the employees actually experience the empowerment. Even if the organizations have the empowerment practices like providing power and open communication it is not necessary that the employee is empowered. Empowerment describes only the condition of work environment. It does not describe employees’ response to these conditions. These responses form the basis for psychological empowerment

Contribution of the exact Breit operator plus the electron state-dependent screening to the multiplet and fine structure of muon-electron atoms

We investigate for very general cases the multiplet and fine structure splitting of muonelectron atoms arising from the coupling of the electron and muon angular momenta, including the effect of the Breit operator plus the electron state-dependent screening. Although many conditions have to be fulfilled simultaneously to observe these effeets, it should be possible to measure them in the 6h- 5g muonic transition in the Sn region.

Values for the electron screening in muonic atoms for all Z

The electron screening correction in the X-ray transitions in muonic atoms is calculated within a relativistic SCF Hartree-Fock procedure for many transitions and all Z.
