Mieux comprendre le syndrome douloureux fémoro-patellaire... pour mieux le traiter [Patellofemoral pain syndrome: understand better in order to treat better].

Le syndrome douloureux fémoro-patellaire (SDFP) est l'une des causes les plus fréquentes de douleur antérieure du genou chez l'adolescent et l'adulte. De par son étiologie complexe, multifactorielle et encore mal comprise, sa prise en charge est un important challenge pour le praticien. Le diagnostic se fait principalement sur l'anamnèse et l'examen clinique du genou mais aussi de l'ensemble du membre inférieur, pouvant parfois nécessiter la réalisation d'une imagerie. Le traitement est dans la grande majorité des cas conservateur, principalement axé sur la rééducation avec de la physiothérapie ciblée et personnalisée. Le traitement chirurgical est réservé aux cas présentant une anomalie structurelle causale. Patellofemoral pain syndrome (PFPS) is one of the most frequent cause of anterior knee pain in adolescents and adults. Due to its complex etiology, which is multifactorial and still poorly understood, its management is a major challenge for the practitioner. The diagnosis is made primarily on the history and clinical examination of the knee, but also of the entire lower limb, which may sometimes require the completion of imaging. The treatment is mostly conservative, focussing on rehabilitation with targeted and personalized therapy. Surgical treatment is reserved for cases with a causal structural lesion.

Services "amis des jeunes": promouvoir des soins adaptés aux adolescents [Youth friendly health services: how to promote quality health care for adolescents].

Beaucoup de jeunes éprouvent des difficultés à demander une aide médicale et psychosociale alors qu'ils en auraient bien besoin. Cela est lié au processus d'autonomisation propre à cette période de la vie : les adolescents souhaitent résoudre leurs problèmes eux-mêmes. Pour améliorer la qualité des soins aux jeunes, l'Organisation mondiale de la santé, avec l'UNICEF et d'autres organismes, a développé le concept de youth friendly health services ; services amis des jeunes. Ce concept repose sur plusieurs principes, comme l'accessibilité, la flexibilité, une formation spécifique du personnel, le respect de la neutralité et de la confidentialité, compétences communicationnelles, etc. L'application de cette approche ne se limite pas aux centres spécialisés en médecine de l'adolescence, mais devra être progressivement implantée dans toutes les structures de soins accueillant des jeunes. Many young people have difficulties requesting medical or psychosocial support, although some badly need it. This difficulty is related to the fact that, as part of their search for autonomy, young people prefer to solve their problems by themselves. To improve the quality of care, the World Health Organization, UNICEF and allied organizations have developed the concept of "Youth friendly health services". This concept includes policies and strategies to improve the accessibility and flexibility, staff's competence and communication skills, etc. Such an approach should not be limited to specialized centers for adolescent health. It should be adopted by all health care institutions dealing with young people.

La metodologia d'intervenció dels treballadors socials en el sistema de les cures pal·liatives

L’atenció a l’etapa final de la vida de les persones és un dels pilars fonamentals de les cures pal·liatives i és des de la professió del treball social que es pot promoure aquesta atenció en concepte de qualitat, tranquil·litat i preservació dels valors de les persones en situació terminal. És per aquesta raó que s’ha elaborat el present document d’investigació, el qual compta inicialment amb un recull bibliogràfic que abraçarà la metodologia d’intervenció dels treballadors socials en el sistema de les cures pal·liatives de l’Estat espanyol i del Regne Unit, país pioner en la creació de les unitats de cures pal·liatives. En aquest recull s’emmarcaran detalladament les diferències existents en termes d’intervenció i de desenvolupament d’aquest àmbit en els dos territoris. La descripció detallada dels dos models d’intervenció pretén donar la resposta a l’interrogant sobre quina és la metodologia d’intervenció que realitzen els treballadors socials en el sistema de cures pal·liatives. Per assolir aquesta resposta, s’adrecen qüestions com els objectius que lideren el treball d’aquests professionals, les funcions que realitzen en la seva pràctica professional diària i les habilitats de les que han de disposar per tal d’aconseguir que la seva intervenció sigui òptima, tant per als mateixos professionals com per a les persones amb les quals intervenen. Posteriorment a la revisió bibliogràfica, es realitzaran tres entrevistes exploratòries a tres treballadors socials de diferents nivells sanitaris que promoguin les cures pal·liatives a Catalunya. S’analitzaran les qüestions treballades en el recull bibliogràfic (objectius, funcions i habilitats dels treballadors socials), les quals permetran comparar la perspectiva teòrica cercada amb la informació primària obtinguda. Finalment, es planteja una proposta de projecte que permetrà aprofundir en la intervenció dels treballadors socials de Catalunya i del Regne Unit, realitzant una comparació entre els dos models a través de la realització de quaranta-vuit entrevistes repartides homogèniament per els dos territoris. D’aquesta manera, s’especificaran totes aquelles accions que es puguin millorar i les intervencions que siguin més òptimes per la tipologia d’atenció que es requereix en els sistemes de les cures pal·liatives d’avui en dia.

Trends and characteristics of attendance at the emergency department of a Swiss university hospital: 2002-2012.

BACKGROUND: The numbers of people attending emergency departments (EDs) at hospitals are increasing. We aimed to analyse trends in ED attendance at a Swiss university hospital between 2002 and 2012, focussing on age-related differences and hospital admission criteria. METHODS: We used hospital administrative data for all patients aged ≥16 years who attended the ED (n = 298,306) at this university hospital between 1 January 2002, and 31 December 2012. We descriptively analysed the numbers of ED visits according to the admission year and stratified by age (≥65 vs <65 years). RESULTS: People attending the ED were on average 46.6 years old (standard deviation 20 years, maximum range 16‒99 years). The annual number of ED attendances grew by n = 6,639 (27.6%) from 24,080 in 2002 to 30,719 in 2012. In the subgroup of patients aged ≥65 the relative increase was 42.3%, which is significantly higher (Pearson's χ2 = 350.046, df = 10; p = 0.000) than the relative increase of 23.4% among patients <65 years. The subgroup of patients ≥65 years attended the ED more often because of diseases (n = 56,307; 85%) than accidents (n = 9,844; 14.9%). This subgroup (patients ≥65 years) was also more often admitted to hospital (Pearson's χ2 = 23,377.190; df = 1; p = 0.000) than patients <65 years. CONCLUSIONS: ED attendance of patients ≥65 years increased in absolute and relative terms. The study findings suggest that staff of this ED may want to assess the needs of patients ≥65 years and, if necessary, adjust the services (e.g., adapted triage scales, adapted geriatric screenings, and adapted hospital admission criteria).

Generalization transitions in Hidden-Layer neural networks for third-order feature discrimination

Stochastic learning processes for a specific feature detector are studied. This technique is applied to nonsmooth multilayer neural networks requested to perform a discrimination task of order 3 based on the ssT-block¿ssC-block problem. Our system proves to be capable of achieving perfect generalization, after presenting finite numbers of examples, by undergoing a phase transition. The corresponding annealed theory, which involves the Ising model under external field, shows good agreement with Monte Carlo simulations.

Transición a la vida adulta de jóvenes con discapacidad intelectual. La opinión de los profesionales de servicios escolares y postescolares = Transition to adulthood of young people with intellectual disabilities. Views of professionals from school and postschool services

La transición a la edad adulta y vida activa es un proceso extremadamente complejo para los jóvenes con discapacidad. Para plantear propuestas de actuación que mejoren sus oportunidades de conseguir objetivos relacionados con la inclusión laboral y social en la vida adulta es imprescindible el diagnóstico en profundidad del contexto en que se construyen y desarrollan los procesos de transición. En este artículo se presenta un estudio en el que se ha aplicado el método Delphi con el propósito de obtener datos sobre la adecuación de los servicios o dispositivos que trabajan con jóvenes con discapacidad a lo largo de su proceso de transición a la edad adulta y vida activa, tanto en el escenario escolar como en el postescolar. Se han constituido dos paneles de expertos, uno con profesionales del ámbito educativo y otro con profesionales que trabajan en servicios postescolares. En ambos casos, los ejes temáticos son: visión del proceso de transición, aspectos curriculares y organizativos de los servicios, existencia de itinerarios de apoyo sistematizados, trabajo colaborativo entre profesionales, acciones de orientación con familias, adecuación de las alternativas postescolares, la formación de los profesionales, y coordinación de servicios. El análisis de los cuestionarios permite constatar las principales dificultades percibidas por los expertos en cada uno de los ámbitos y establece líneas básicas de actuación para mejorar los procesos de tránsito, entre las cuales destaca la necesidad de reforzar el papel de los equipos multiprofesionales en la articulación de redes de trabajo interprofesional

¿Continuidad o fragmentación? Percepción de los profesionales sobre la coordinación entre servicios en los procesos de tránsito a la vida adulta de los jóvenes con discapacidad intelectual

This article is part of a research focusing on the process of transition to adulthood of young people with intellectual disabilities. Specifically, this study analyses transition partnership programs, as the professionals involved in them see them. The information is obtained in two stages: in the first stage 45 interviews to professionals working in this field are conducted. In the second stage we develop a study applying the Delphi method in which two panels of experts, the first one with educational professionals and the second one with professionals working with afters chool services, were asked about several topics. The results show a lack of continuity underlying the actions taken in support of young people with ID during the transition process. Insufficient information and collaboration among services and professionals and a lack of leadership are the main problems perceived by professionals. The study helps to identify problems in the transition partnership programs and establishes actions in order to enhance the transition process

Equating accelerometer estimates among youth: The Rosetta Stone 2.

OBJECTIVES: Different accelerometer cutpoints used by different researchers often yields vastly different estimates of moderate-to-vigorous intensity physical activity (MVPA). This is recognized as cutpoint non-equivalence (CNE), which reduces the ability to accurately compare youth MVPA across studies. The objective of this research is to develop a cutpoint conversion system that standardizes minutes of MVPA for six different sets of published cutpoints. DESIGN: Secondary data analysis. METHODS: Data from the International Children's Accelerometer Database (ICAD; Spring 2014) consisting of 43,112 Actigraph accelerometer data files from 21 worldwide studies (children 3-18 years, 61.5% female) were used to develop prediction equations for six sets of published cutpoints. Linear and non-linear modeling, using a leave one out cross-validation technique, was employed to develop equations to convert MVPA from one set of cutpoints into another. Bland Altman plots illustrate the agreement between actual MVPA and predicted MVPA values. RESULTS: Across the total sample, mean MVPA ranged from 29.7MVPAmind(-1) (Puyau) to 126.1MVPAmind(-1) (Freedson 3 METs). Across conversion equations, median absolute percent error was 12.6% (range: 1.3 to 30.1) and the proportion of variance explained ranged from 66.7% to 99.8%. Mean difference for the best performing prediction equation (VC from EV) was -0.110mind(-1) (limits of agreement (LOA), -2.623 to 2.402). The mean difference for the worst performing prediction equation (FR3 from PY) was 34.76mind(-1) (LOA, -60.392 to 129.910). CONCLUSIONS: For six different sets of published cutpoints, the use of this equating system can assist individuals attempting to synthesize the growing body of literature on Actigraph, accelerometry-derived MVPA.

Characterization of clinical and electrocardiographic findings in a youth population

Resting 12-lead electrocardiogram (ECG) has been employed in the evaluation of young asymptomatic subjects to detect pre-existing heart diseases. Although the incorporation of routine ECG remains controversial, there is increasing evidence that cardiomyopathies and ion channelopathies show ECG changes as the initial manifestation. The causes of sudden cardiac death in young people show a significant geographical variation. We aim to determine the prevalence and spectrum of ECG findings in a youth population. Methodology: From May 2010 to April 2013, a total of 976 young secondary school students (mean age, 14 years; range, 13-15) underwent voluntary medical screening that included a resting 12-lead ECG and structured clinical survey. Subjects with abnormal ECG findings were classified into two groups: major ECG findings group, which fulfilled a pre-specified checklist to screen for principal structural and electrical cardiopathies, and minor ECG findings group showing other ECG changes. The major ECG findings group was referred for secondary diagnostic tests at a tertiary institution. Results: Of the 976 subjects screened, 252 (25.82%; CI95%, 23.17-28.66) had ECG findings. Of note, 17 (1.74%) had major findings and 235 (24.08%) had minor findings on ECG. The prevalence of cardiovascular pathology within the major ECG findings group was 35.29%. The prevalence of ECG abnormalities was significantly higher in males than in females (29% vs 20.9%, P<0.01). Conclusions: The prevalence of ECG findings in a youth population was 25.82%. There were significant gender differences. The inclusion of universal ECG screening, in addition to medical history, may increase the sensitivity of a cardiovascular screening program. Knowledge of the spectrum and prevalence of ECG findings and disease conditions would be pivotal in designing customized screening programs

Revisió del model inclusiu en l’àmbit de l’educació no formal del futbol base a partir del criteri d’agrupació

Recerca centrada en l’anàlisi de característiques concretes de l’educació inclusiva en un entorn d’educació no formal, com és el futbol base. El criteri que s’ha utilitzat per realitzar l’anàlisi són els agrupaments. Des de l’educació inclusiva es promouen els agrupaments heterogenis, una forma d’agrupar a l’alumnat tenint en compte les seves diferències, per tal d’enriquir-se entre tot l’alumnat i treure profit d’elles. A la vegada aquest agrupament es caracteritza per fomentar la igualtat d’oportunitats en l’aprenentatge dels alumnes. En canvi, al futbol base predominen els agrupaments homogenis, distribuint als jugadors segons el seu nivell en diferents equips. A la recerca es fa una comparació entre l’opinió de diferents membres involucrats en el món del futbol base de dues entitats esportives, un club de futbol, on es fan els grups de forma homogènia, i una escola de futbol, on es fan els agrupaments de forma heterogènia. Els resultats mostren que realitzant agrupaments homogenis no s’assegura que tots els jugadors tinguin les mateixes oportunitats d’aprenentatge i que el nivell competencial dels jugadors en edat de formació pot ser un element que fomenti desigualtats en el seu procés d’aprenentatge esportiu.

New approximation to the third-order density : application to the calculation of correlated multicenter indices

In this work we present the formulas for the calculation of exact three-center electron sharing indices (3c-ESI) and introduce two new approximate expressions for correlated wave functions. The 3c-ESI uses the third-order density, the diagonal of the third-order reduced density matrix, but the approximations suggested in this work only involve natural orbitals and occupancies. In addition, the first calculations of 3c-ESI using Valdemoro's, Nakatsuji's and Mazziotti's approximation for the third-order reduced density matrix are also presented for comparison. Our results on a test set of molecules, including 32 3c-ESI values, prove that the new approximation based on the cubic root of natural occupancies performs the best, yielding absolute errors below 0.07 and an average absolute error of 0.015. Furthemore, this approximation seems to be rather insensitive to the amount of electron correlation present in the system. This newly developed methodology provides a computational inexpensive method to calculate 3c-ESI from correlated wave functions and opens new avenues to approximate high-order reduced density matrices in other contexts, such as the contracted Schrödinger equation and the anti-Hermitian contracted Schrödinger equation
