Age does not hamper the response to pulmonary rehabilitation of COPD patients

Pulmonary rehabilitation (PR) improves health status and exercise tolerance, but not respiratory function in patients with chronic obstructive pulmonary disease (COPD). The objective of the study was to identify predictors of improvement in the 6-min walked distance (6'WD) in elderly COPD patients after PR. Methods: this was a prospective observational study performed in an ambulatory rehabilitation setting. The authors enrolled 74 patients aged 65-83 years (mean: 74.2, SD: 4.4) with stable COPD in GOLD stage 3-4. About half (45.6%) of them had a basal O2 saturation of 90% or less. After a baseline multi-dimensional assessment, patients underwent a 20-session rehabilitation cycle including training of the upper and lower extremities, and respiratory exercises, along with education sessions.

Report of the Advisory Group on Post Primary Teacher Education

The occasion of this report on Teacher Education is timely. The teaching profession is now confronted with major challenges. Schooling has changed very radically in the recent past. Other review exercises of the education system have taken place and it is a time when a new legislative framework, better accommodated to the diversity of the range of duties and responsibilities of the teacher and school, is emerging. It is anticipated that the Report will stimulate debate, secure a new platform for development and provide for a framework for teacher education models which is better disposed towards the well being of the profession and the service to society it wishes to provide.

Insufficient coping behavior under chronic stress and vulnerability to psychiatric disorders

Epidemiological data indicate that 75% of subjects with major psychiatric disorders have their onset in the age range of 17-24 years. An estimated 35-50% of college and university students drop out prematurely due to insufficient coping skills under chronic stress, while 85% of students receiving a psychiatric diagnosis withdraw from college/university prior to the completion of their education. In this study we aimed at developing standardized means for identifying students with insufficient coping skills under chronic stress and at risk for mental health problems. A sample of 1,217 college students from 3 different sites in the U.S. and Switzerland completed 2 self-report questionnaires: the Coping Strategies Inventory "COPE" and the Zurich Health Questionnaire "ZHQ" which assesses "regular exercises", "consumption behavior", "impaired physical health", "psychosomatic disturbances", and "impaired mental health". The data were subjected to structure analyses by means of a Neural Network approach. We found 2 highly stable and reproducible COPE scales that explained the observed inter-individual variation in coping behavior sufficiently well and in a socio-culturally independent way. The scales reflected basic coping behavior in terms of "activity-passivity" and "defeatism-resilience", and in the sense of stable, socio-culturally independent personality traits. Correlation analyses carried out for external validation revealed a close relationship between high scores on the defeatism scale and impaired physical and mental health. This underlined the role of insufficient coping behavior as a risk factor for physical and mental health problems. The combined COPE and ZHQ instruments appear to constitute powerful screening tools for insufficient coping skills under chronic stress and for risks of mental health problems.

Effects of two types of fatigue on the VO(2) slow component.

The aim of the study was to test the hypothesis of the involvement of type II fibres in the V.O (2) slow component phenomenon by using two prior fatiguing protocols on the knee extensor muscles. Nine subjects performed three constant-load cycling exercises at a work rate corresponding to 80 % of their V.O (2) max: (i) preceded by a 20-min fatiguing protocol using electromyostimulation (EMS), (ii) preceded by a 20-min fatiguing protocol using voluntary contractions (VOL), and (iii) without fatiguing protocol (NFP). Voluntary and evoked neuromuscular properties of the knee extensor muscles were tested before (PRE) and after (POST) the two fatiguing protocols. Results show a significant reduction in voluntary force after both fatiguing protocols (-19.9 % and -11.8 %, in EMS and VOL, respectively p<0.01). After EMS, this decrease was greater than after VOL (p<0.05) and was combined with a slackening of muscle contractile properties which was absent after VOL (p<0.05). Regarding the effects on oxygen uptake kinetics, the appearance of the slow component was delayed after EMS and its amplitude was lower than those obtained in VOL and NFP conditions (0.48+/-0.07 vs. 0.75+/-0.09 and 0.69+/-0.08 L . min (-1), respectively; p<0.05). It can thus be concluded that exercises dedicated to preferentially fatiguing type II fibres may alter V.O (2) kinetics.

Addition of inspiratory resistance increases the amplitude of the slow component of O2 uptake kinetics.

The contribution of respiratory muscle work to the development of the O(2) consumption (Vo(2)) slow component is a point of controversy because it has been shown that the increased ventilation in hypoxia is not associated with a concomitant increase in Vo(2) slow component. The first purpose of this study was thus to test the hypothesis of a direct relationship between respiratory muscle work and Vo(2) slow component by manipulating inspiratory resistance. Because the conditions for a Vo(2) slow component specific to respiratory muscle can be reached during intense exercise, the second purpose was to determine whether respiratory muscles behave like limb muscles during heavy exercise. Ten trained subjects performed two 8-min constant-load heavy cycling exercises with and without a threshold valve in random order. Vo(2) was measured breath by breath by using a fast gas exchange analyzer, and the Vo(2) response was modeled after removal of the cardiodynamic phase by using two monoexponential functions. As anticipated, when total work was slightly increased with loaded inspiratory resistance, slight increases in base Vo(2), the primary phase amplitude, and peak Vo(2) were noted (14.2%, P < 0.01; 3.5%, P > 0.05; and 8.3%, P < 0.01, respectively). The bootstrap method revealed small coefficients of variation for the model parameter, including the slow-component amplitude and delay (15 and 19%, respectively), indicating an accurate determination for this critical parameter. The amplitude of the Vo(2) slow component displayed a 27% increase from 8.1 +/- 3.6 to 10.3 +/- 3.4 ml. min(-1). kg(-1) (P < 0.01) with the addition of inspiratory resistance. Taken together, this increase and the lack of any differences in minute volume and ventilatory parameters between the two experimental conditions suggest the occurrence of a Vo(2) slow component specific to the respiratory muscles in loaded condition.

Assessorament curricular i orientació als docents sobre estratègies en la resolució de problemes matemàtics

A l'escola on treballo s'està fent l'avaluació interna de l'àrea de matemàtiques, concretament en la tasca de resolució de problemes. Durant el mes de gener es van passar uns exercicis de resolució d'El Quintet als alumnes de cicle superior; els mestres van valorar on s'havien comès els errors, si eren per comprensió, per mecànica de les operacions o per resposta incorrecta, i els resultats obtinguts van demostrar que els errors es produïen en diferents parts del problema. Això va fer pensar als docents que les dificultats de progrés per part dels alumnes eren en el propi procés d'ensenyament, que no era complet o que hi havia aspectes que no es treballaven prou. Per tant, l'interès dels mestres és saber: on es cometen errades, per què i com es pot aconseguir un treball millor.

Eficacia de un programa de entrenamiento intradiálisis de fuerza-resistencia en combinación con electroestimulación neuromuscular: mejora en la capacidad funcional, fuerza, y calidad de vida

The purpose of this study was to determine the efficacy of a programme of strength-stamina exercises during haemodialysis, in improving muscular strength, quality of life and functional capacity to carry out everyday activities. A quantitative, experimental pre-test and post-test study was carried out. A programme of strength-stamina exercises in combination with neuromuscular electrostimulation was applied to 10 patients undergoing haemodialysis. These were three simple exercises adapted to the position in which haemodialysis was carried out. All the patients showed a significant improvement in strength, measured using functional tests to carry out everyday activities: walking (6-MWT) and sit-to-stand tests (10-STS). These tests were measured before and after the training programme. They also showed an improvement in the physical dimension of the quality of life measured using the specific questionnaire for renal patients, KDQOL-SFTM.

Effect of a general school-based physical activity intervention on bone mineral content and density: A cluster-randomized controlled trial.

Background: Specific physical loading leads to enhanced bone development during childhood. A general physical activity program mimicking a real-life situation was successful at increasing general physical health in children. Yet, it is not clear whether it can equally increase bone mineral mass. We performed a cluster-randomized controlled trial in children of both gender and different pubertal stages to determine whether a school-based physical activity (PA) program during one school-year influences bone mineral content (BMC) and density (BMD), irrespective of gender.Methods: Twenty-eight 1st and 5th grade (6-7 and 11-12 year-old) classes were cluster randomized to an intervention (INT, 16 classes, n = 297) and control (CON; 12 classes, n = 205) group. The intervention consisted of a multi-component PA intervention including daily physical education with at least 10 min of jumping or strength training exercises of various intensities. Measurements included anthropometry, and BMC and BMD of total body, femoral neck, total hip and lumbar spine using dual-energy X-ray absorptiometry (DXA). PA was assessed by accelerometers and Tanner stages by questionnaires. Analyses were performed by a regression model adjusted for gender, baseline height and weight, baseline PA, post-intervention pubertal stage, baseline BMC, and cluster.Results: 275 (72%) of 380 children who initially agreed to have DXA measurements had also post-intervention DXA and PA data. Mean age of prepubertal and pubertal children at baseline was 8.7 +/- 2.1 and 11.1 +/- 0.6 years, respectively. Compared to CON, children in INT showed statistically significant increases in BMC of total body, femoral neck, and lumbar spine by 5.5%, 5.4% and 4.7% (all p < 0.05), respectively, and BMD of total body and lumbar spine by 8.4% and 7.3% (both p < 0.01), respectively. There was no gender*group, but a pubertal stage*group interaction consistently favoring prepubertal children.Conclusion: A general school-based PA intervention can increase bone health in elementary school children of both genders, particularly before puberty.

Music performance anxiety among full-time music students

Introduction Music performance anxiety (MPA, often referred to as "stage fright") is one of the leading severe medical problems among musicians. For about 15-25% of musicians MPA is a serious problem. Particularly high levels of MPA are observed among music students. Musical performance can induce negative emotions, including anxiety, which in some individuals can approach extreme levels of terror and take the form of panic attack, impair the quality of the performance, lead to avoidance of performance situations, and consequently have debilitating effects on the career. Coping efforts used by musicians in their attempts to manage MPA, such as sedatives, alcohol, and β-blockers can have deleterious health side-effects. Music ranks high in the cultural and economic life of Switzerland. In ten university music schools, students from all around the world are educated to become professional musicians. Despite the importance of musical education in Switzerland, data concerning the phenomenon of MPA are largely lacking. Goal and Methods The main goal of this research was to survey the occurrence, experience, and management of MPA among full-time music students in French Swiss conservatories. A questionnaire was developed based on the literature and interviews with music students and teachers and distributed to all the students of the conservatories of Fribourg, Geneva, Lausanne, and Neuchâtel in the spring 2007. 194 students (61% women) returned the questionnaire. Results The size of the problem: MPA is a major problem for 1/3 of the students (ranks 3 and 4). The consequences of MPA: 22% and 35% of the students think that they have failed exams and auditions, respectively, because of MPA. Further, 25% of the students have already avoided performing and 11% have interrupted public performances because of MPA. Coping with MPA: 90% of the students have never used alcohol prior to performing, whereas 97% and 81%, respectively, have never used recreation drugs and medication. The majority of students use relaxation exercises, respiratory exercises, and meditation techniques to prepare themselves. About ¾ of the students think that the use of alcohol and recreational drugs to manage MPA is never justified. 53% of the students think that the use of medication is justified on some occasions. Need for information and support: 66% of the students would like to receive more support and help to cope with music performance situations. This support should mainly come from their teachers and specialists. 53% of the students know nothing or little about possible means for the management of MPA. About 50% consider themselves not at all or little informed about the possible risks associated with the consumption of alcohol, recreational drugs, and medication for the management of performance situations. 89% would like to know more about MPA and 94% think that this topic should be discussed much more in their musical education at the conservatory. Conclusions The results of this survey indicate that MPA is a major problem for 1/3 of the students with serious consequences on their career. There is a huge need for more information and support on how to manage the stress due to performance situations. The use of alcohol, recreational drugs, and medication is modest but the students are poorly informed about possible side-effects of these coping strategies. It seems clear that more should be done in the French Swiss conservatories about music performance anxiety to inform, educate, and prepare the students for their future professional career.

La práctica médica en el ejercico físico en Barcelona en los principios del siglo XX

La tesis titulada “La práctica médica en el ejercicio físico en la Barcelona de principios del siglo XX” trata de examinar cómo se relacionaba la práctica médica con los ejercicios físicos como la gimnasia y el deporte, y saber si realmente se llegó a formar una especialidad médica llamada medicina del deporte en la Barcelona de los principios del siglo XX. La primera parte se titula “Perspectiva histórica del ejercicio físico y la medicina”, y trata de la relación general entre el ejercicio físico y la medicina desde el punto de macro-vista histórico y regional. La segunda parte se titula “Hacia la formación de la especialización de la medicina del deporte en Barcelona”, y analiza la práctica médica relacionada con el deporte en una ciudad concreta durante un tiempo determinado, es decir, desde un punto de micro-vista. En el fondo de la creación de las especialidades médicas a partir de mediados del siglo XIX existe la formación de una sociedad moderna, simbolizada por el sistema administrativo de la democracia nacional y el sistema económico del capitalismo. Considerando los elementos comprendidos dentro del sistema de la modernidad que provocaron la especialización médica tales como la urbanización, la industrialización, el aumento de la población, el interés estatal, el desarrollo de la prensa, el elevado interés público, el progreso intelectual y tecnológico de la ciencia y la medicina, la creación de un sistema de atención de la salud, la formación y participación en las instituciones internacionales, el cambio de la identidad de los médicos, y la reposición de la medicina holística, investigo integralmente la formación de la especialidad de la medicina del deporte en Catalunya, y lo caracterizo por las iniciativas privadas emprendidas por un sector experto y profano, y la ausencia de un interés estatal suficiente en la dicha especialidad.

Telehealth system (e-CUIDATE) to improve quality of life in breast cancer survivors: rationale and study protocol for a randomized clinical trial.

BACKGROUND Breast cancer survivors suffer physical impairment after oncology treatment. This impairment reduces quality of life (QoL) and increase the prevalence of handicaps associated to unhealthy lifestyle (for example, decreased aerobic capacity and strength, weight gain, and fatigue). Recent work has shown that exercise adapted to individual characteristics of patients is related to improved overall and disease-free survival. Nowadays, technological support using telerehabilitation systems is a promising strategy with great advantage of a quick and efficient contact with the health professional. It is not known the role of telerehabilitation through therapeutic exercise as a support tool to implement an active lifestyle which has been shown as an effective resource to improve fitness and reduce musculoskeletal disorders of these women. METHODS / DESIGN This study will use a two-arm, assessor blinded, parallel randomized controlled trial design. People will be eligible if: their diagnosis is of stages I, II, or IIIA breast cancer; they are without chronic disease or orthopedic issues that would interfere with ability to participate in a physical activity program; they had access to the Internet and basic knowledge of computer use or living with a relative who has this knowledge; they had completed adjuvant therapy except for hormone therapy and not have a history of cancer recurrence; and they have an interest in improving lifestyle. Participants will be randomized into e-CUIDATE or usual care groups. E-CUIDATE give participants access to a range of contents: planning exercise arranged in series with breathing exercises, mobility, strength, and stretching. All of these exercises will be assigned to women in the telerehabilitation group according to perceived needs. The control group will be asked to maintain their usual routine. Study endpoints will be assessed after 8 weeks (immediate effects) and after 6 months. The primary outcome will be QoL measured by The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 version 3.0 and breast module called The European Organization for Research and Treatment of Cancer Breast Cancer-Specific Quality of Life questionnaire. The secondary outcomes: pain (algometry, Visual Analogue Scale, Brief Pain Inventory short form); body composition; physical measurement (abdominal test, handgrip strength, back muscle strength, and multiple sit-to-stand test); cardiorespiratory fitness (International Fitness Scale, 6-minute walk test, International Physical Activity Questionnaire-Short Form); fatigue (Piper Fatigue Scale and Borg Fatigue Scale); anxiety and depression (Hospital Anxiety and Depression Scale); cognitive function (Trail Making Test and Auditory Consonant Trigram); accelerometry; lymphedema; and anthropometric perimeters. DISCUSSION This study investigates the feasibility and effectiveness of a telerehabilitation system during adjuvant treatment of patients with breast cancer. If this treatment option is effective, telehealth systems could offer a choice of supportive care to cancer patients during the survivorship phase.

Le mouvement peut-il guérir? : histoire de l'engagement des médecins français dans l'élaboration de l'éducation physique (1741-1888)

Résumé : Cette recherche doctorale analyse l'engagement des médecins français autour de l'éducation physique entre 1741 et 1888. Basé sur un travail prosopographique d'identification des médecins qui ont participé à l'élaboration de l'éducation physique, ce travail repose sur une mise en dialogue de leurs prises de position respectives. Pour réaliser cette enquête, nous avons compulsé un large corpus de sources primaires, composé des ouvrages consacrés à la gymnastique médicale mais aussi une très large portion de la production d'imprimés touchant à l'anatomie, l'hygiène, la thérapeutique, la physiologie, l'orthopédie, etc. Le corpus contient également des articles des principaux dictionnaires médicaux de la période et des principales revues médicales du XIXe siècle. Avec une approche critique de l'historiographie et à partir de ce corpus, nous avons travaillé dans le cadre de contextes définis pour saisir au plus près les logiques sociales et scientifiques amenant les médecins auprès de l'éducation physique. Trois conjonctures successives structurent l'engagement médical. Entre 1741 et 1817, la thèse retrace l'émergence d'un questionnement ; les années 1817-1847 constituent un « moment orthopédique » dans la formulation de la gymnastique ; et finalement entre 1847 et 1888, on observe une diversification des voies de légitimation médicale des exercices du corps. Ces trois moments de l'histoire des « discours gymniques médicaux » proposent un certain nombre de convergences : la prégnance de l'orthopédie, une certaine concentration autour de la santé des corps féminins, l'inclusion dans un « projet hygiéniste » ; mais aussi des divergences et des singularités : relatives à la progressive structuration en cours du champ médical, à l'implication progressive du politique (surtout après 1845/1850), aux transformations des pathologies/doctrines médicales « dominantes », ainsi qu'à l'importance plus ou moins forte de l'une ou l'autre des facettes de l'éducation physique (militaire, athlétique, « médicinale » ou pédagogique). Le processus est aussi celui de l'expérimentation de la curation de certaines pathologies (scolioses, affections nerveuses), dans des configurations idéologiques/scientifiques marquées par la « dégénération » (XVIIIe siècle), l'anatomie pathologique (début du XIXe siècle) et plus tard la « dégénérescence » et les affections nerveuses (après 1850). Dans le cadre d'une dynamique d'inspiration « foucaldienne », ces recommandations évoluent d'une anatomopolitique - caractérisée par un essor de discours empreints d'anatomie au XVIIIe siècle - vers une biopolitique - caractérisée par l'engagement de l'Etat qui fait de la gymnastique une discipline d'enseignement, pensée à des fins hygiéniques dans la seconde moitié du XIXe - où le processus réside en fait dans une biologisation progressive des recommandations pratiques. Observée à l'aune de la formulation médicale de l'éducation physique, la biopolitique n'est pas réalisée dans la seconde moitié du XVIIIe, elle se compose lentement aux marges de l'institution scolaire et des gymnastiques pédagogico-militaires pour constituer un projet thérapeutique et hygiénique plus construit après 1850. Abstract : This dissertation analyzes French doctor's involvement in debates and initiatives concerning physical education between 1741 and 1888. Based on a prosopographic inventory of those physicians who participated in the development of physical education, it explores the variety of their discourses with respect to the practice of physical exercises. This investigation relies on a large selection of primary sources: works devoted to medical gymnastic, but also medical treatises related to anatomy, hygiene, therapeutics, physiology, orthopedics, etc. The sources also include articles from the major medical dictionaries and journals of the nineteenth century. These documents are used to explore the socio-scientific mechanisms that underlay physicians' commitment to physical education. Three chronological periods structure medical engagement in the area of physical education. Between 1741 and 1817 the thesis traces the emergence of a questioning; the years 1817 to 1847 represent an « orthopedic moment » in the development of gymnastics; finally between 1847 and 1888, one witnesses a diversification of the legitimation process between medicine and gymnastics. These three moments in the history of « medical and gymnastic discourses » offer a number of similarities: the weight of orthopedics, the ongoing focus on the health of the female body, and the association of these discourses with a « hygienic project ». But differences also distinguish these periods as the medical field became more structured and new medical doctrines became dominant, with the increasing involvement of politics (especially after 1850), and with the changing weight of priorities within physical education (military, athletic, « medical » or pedagogic). Medical discourses centered on the curing of certain diseases (scoliosis or nervous disorders) are analyzed within an ideological configuration marked by the idea of « degeneration » (in the eighteenth century), « pathological anatomy » (in the early nineteenth century) and later « dégénérescence » associated with nervous disorders (after 1850). The dissertation draws on Foucault's historical epistemology to understand how medical recommendations evolve from an anatomopolitics - characterized by a surge in anatomical discourses - toward a biopolitics - characterized by the commitment of the State to introduce gymnastics for hygienic purposes into schools in the second half of the nineteenth century. This process reveals a progressive "biologization" of practical recommendations. The medical discourses about physical education show that Foucault's biopolitical power is not achieved in the second half of the eighteenth century, but develops slowly at the margins of the school system and of pedagogical and military gymnastic, becoming a veritable hygienic and therapeutic project only after 1850.

Fitness, sport et pression artérielle [Fitness, sports and blood pressure].

Blood pressure is lowered for a few hours after aerobic exercise, but also after resistance exercise, although for a shorter period of time. An exercise program can significantly lower resting and ambulatory BP measurements. Multiple mechanisms interact for the BP lowering effect, such as decreased total peripheral resistance, enhanced endothelial function, diminished sympathetic or rennin plasmatic activity, structural vascular modifications and baroreceptor reflex modulation. New exercises like eccentric or isometric (handgrip) contractions are promising. Resistance activities have long been considered dangerous for blood vessels because of increased arterial stiffness, but if the intensity remains moderate and aerobic exercises are integrated, then the effects are altogether beneficial.
