The Brief Psychiatric Rating Scale (version 4.0) factorial structure and its sensitivity in the treatment of outpatients with unipolar depression.

The 24-item Brief Psychiatric Rating Scale (BPRS, version 4.0) enables the rater to measure psychopathology severity. Still, little is known about the BPRS's reliability and validity outside of the psychosis spectrum. The aim of this study was to examine the factorial structure and sensitivity to change of the BPRS in patients with unipolar depression. Two hundred and forty outpatients with unipolar depression were administered the 24-item BPRS. Assessments were conducted at intake and at post-treatment in a Crisis Intervention Centre. An exploratory factor analysis of the 24-item BPRS produced a six-factor solution labelled "Mood disturbance", "Reality distortion", "Activation", "Apathy", "Disorganization", and "Somatization". The reduction of the total BPRS score and dimensional scores, except for "Activation", indicates that the 24-item BPRS is sensitive to change as shown in patients that appeared to have benefited from crisis treatment. The findings suggest that the 24-item BPRS could be a useful instrument to measure symptom severity and change in symptom status in outpatients presenting with unipolar depression.

Phenotip - a web-based instrument to help diagnosing fetal syndromes antenatally.

Prenatal ultrasound can often reliably distinguish fetal anatomic anomalies, particularly in the hands of an experienced ultrasonographer. Given the large number of existing syndromes and the significant overlap in prenatal findings, antenatal differentiation for syndrome diagnosis is difficult. We constructed a hierarchic tree of 1140 sonographic markers and submarkers, organized per organ system. Subsequently, a database of prenatally diagnosable syndromes was built. An internet-based search engine was then designed to search the syndrome database based on a single or multiple sonographic markers. Future developments will include a database with magnetic resonance imaging findings as well as further refinements in the search engine to allow prioritization based on incidence of syndromes and markers.

Validation de la version française du score de hanche d'Oxford-12

Fondement L'appréciation objective du résultat des actes chirurgicaux fait partie de la démarche d'évaluation des pratiques professionnelles, notamment en chirurgie orthopédique pour le résultat des prothèses articulaires. Dans cette optique, les questionnaires « auto-administrés » par les patients offrent une solution séduisante, mais peu utilisée en France. Le questionnaire anglais Oxford Hip Score en 12 questions (OHS-12) a été sélectionné pour cette étude en raison de sa facilité d'utilisation. Hypothèse Le but de ce travail était de valider la traduction française du score d'autoévaluation Oxford-12 et d'en confronter les résultats à ceux des scores fonctionnels de références, de Harris (HHS) et de Merle d'Aubigné (PMA). Matériel et méthode À partir d'une série clinique de 242 patients candidats à une arthroplastie de hanche, une validation de la traduction en langue française de ce questionnaire a été réalisée, ainsi qu'une évaluation de sa cohérence par confrontation des données obtenues en préopératoire avec celles provenant des deux scores cliniques de référence. Résultats La traduction a été validée selon le processus de traduction inverse du français à l'anglais avec correction de toute déviation ou contresens après comparaison systématisée avec le questionnaire original anglais. La moyenne du score global OHS-12 était de 43,8 points (22 à 60 points) avec une bonne distribution de la valeur globale des trois scores comparés. La corrélation était excellente entre OHS et HHS, mais une corrélation de niveau identique entre OHS et PMA n'a été obtenue que pour l'association des paramètres douleur et fonction, après exclusion du critère mobilité relativement surreprésenté dans le score PMA. Discussion et conclusion Le recours à des questionnaires subjectifs qui apportent une appréciation personnelle du résultat de l'arthroplastie par le patient est facilement applicable à grande échelle. Ce travail permet de mettre à la disposition des chirurgiens orthopédistes français une version traduite et validée d'un score d'autoévaluation fiable et internationalement reconnu. Les résultats obtenus nous incitent à privilégier l'utilisation de ce questionnaire en complément des scores et méthodes d'évaluation classiques.

The M-Coffee web server: a meta-method for computing multiple sequence alignments by combining alternative alignment methods.

The M-Coffee server is a web server that makes it possible to compute multiple sequence alignments (MSAs) by running several MSA methods and combining their output into one single model. This allows the user to simultaneously run all his methods of choice without having to arbitrarily choose one of them. The MSA is delivered along with a local estimation of its consistency with the individual MSAs it was derived from. The computation of the consensus multiple alignment is carried out using a special mode of the T-Coffee package [Notredame, Higgins and Heringa (T-Coffee: a novel method for fast and accurate multiple sequence alignment. J. Mol. Biol. 2000; 302: 205-217); Wallace, O'Sullivan, Higgins and Notredame (M-Coffee: combining multiple sequence alignment methods with T-Coffee. Nucleic Acids Res. 2006; 34: 1692-1699)] Given a set of sequences (DNA or proteins) in FASTA format, M-Coffee delivers a multiple alignment in the most common formats. M-Coffee is a freeware open source package distributed under a GPL license and it is available either as a standalone package or as a web service from www.tcoffee.org.

Identifying the unmet health needs of patients with congenital hypogonadotropic hypogonadism using a web-based needs assessment: implications for online interventions and peer-to-peer support.

BACKGROUND: Patients with rare diseases such as congenital hypogonadotropic hypogonadism (CHH) are dispersed, often challenged to find specialized care and face other health disparities. The internet has the potential to reach a wide audience of rare disease patients and can help connect patients and specialists. Therefore, this study aimed to: (i) determine if web-based platforms could be effectively used to conduct an online needs assessment of dispersed CHH patients; (ii) identify the unmet health and informational needs of CHH patients and (iii) assess patient acceptability regarding patient-centered, web-based interventions to bridge shortfalls in care. METHODS: A sequential mixed-methods design was used: first, an online survey was conducted to evaluate health promoting behavior and identify unmet health and informational needs of CHH men. Subsequently, patient focus groups were held to explore specific patient-identified targets for care and to examine the acceptability of possible online interventions. Descriptive statistics and thematic qualitative analyses were used. RESULTS: 105 male participants completed the online survey (mean age 37 ± 11, range 19-66 years) representing a spectrum of patients across a broad socioeconomic range and all but one subject had adequate healthcare literacy. The survey revealed periods of non-adherence to treatment (34/93, 37%) and gaps in healthcare (36/87, 41%) exceeding one year. Patient focus groups identified lasting psychological effects related to feelings of isolation, shame and body-image concerns. Survey respondents were active internet users, nearly all had sought CHH information online (101/105, 96%), and they rated the internet, healthcare providers, and online community as equally important CHH information sources. Focus group participants were overwhelmingly positive regarding online interventions/support with links to reach expert healthcare providers and for peer-to-peer support. CONCLUSION: The web-based needs assessment was an effective way to reach dispersed CHH patients. These individuals often have long gaps in care and struggle with the psychosocial sequelae of CHH. They are highly motivated internet users seeking information and tapping into online communities and are receptive to novel web-based interventions addressing their unmet needs.
