Proprioceptive neuromuscular facilitation in HTLV-I-associated myelopathy/tropical spastic paraparesis

Introduction: Human T cell lymphotropic virus type I-associated myelopathy/tropical spastic paraparesis (HAM/TSP) can impact the independence and motricity of patients. The aims of this study were to estimate the effects of physiotherapy on the functionality of patients with HAM/TSP during the stable phase of the disease using proprioceptive neuromuscular facilitation (PNF) and to compare two methods of treatment delivery. Methods: Fourteen patients with human T cell lymphotropic virus type I (HTLV-I) were randomly allocated into two groups. In group I (seven patients), PNF was applied by the therapist, facilitating the functional activities of rolling, sitting and standing, walking and climbing and descending stairs. In group II (seven patients), PNF was self-administered using an elastic tube, and the same activities were facilitated. Experiments were conducted for 1h twice per week for 12 weeks. Low-back pain, a modified Ashworth scale, the functional independence measure (FIM) and the timed up and go test (TUG) were assessed before and after the interventions. Results: In the within-group evaluation, low-back pain was significantly reduced in both groups, the FIM improved in group II, and the results of the TUG improved in group I. In the inter-group analysis, only the tone was lower in group II than in group I. Conclusions: Both PNF protocols were effective in treating patients with HAM/TSP.

Variation of the Chlorophyll a Related to Sea Surface Temperature, Wind and Geostrophic Currents in the Cape Verde Region Using Satellite Data

We present a comparative analysis of satellite derived climatologies in the Cape Verde region (CV). In order to establish chlorophyll a variability, in relation to other oceanographic phenomena, a set of, relatively long (from five to eight years), time series of chlorophyll a, sea surface temperature, wind and geostrophic currents, were ensembled for the Eastern Central Atlantic (ECA). We studied seasonal and inter-annual variability of phytoplankton concentration, in relation to the rest of the variables, with a special focus in CV. We compared the situation within the archipelago with those of the surrounding marine environments, such as the North West African Upwelling (NWAU), North Atlantic Subtropical Gyre (NASTG), North Equatorial Counter Current (NECC) and Guinea Dome (GD). At the seasonal scale, CV region behaves partly as the surrounding areas, nevertheless, some autochthonous features were also found. The maximum peak of the pigment having a positive correlation with temperature is found at the end of the year for all the points in the archipelago; a less remarkable rise with negative correlation is also detected in February for points CV2 and CV4. This is behavior that none of the surrounding environments have shown. This enrichment was found to be preceded by a drastic drop in wind intensity (SW Monsoon) during summer months. The inter-annual analysis shows a tendency for decreasing of the chlorophyll a concentration.

Les effets du débat public dans la nouvelle ville de Montréal : regard sur le plan d'urbanisme et sa mise en oeuvre

Débat public, participation, délibération, autant de termes utilisés pour parler de normes et de dispositifs qui participeraient au nouvel « impératif délibératif » (Blondiaux et Sintomer 2002). Ce mémoire présente une analyse du débat public sur le plan d'urbanisme de Montréal avec un schéma d'analyse inspiré de celui de Simard et Fourniau (2007). Notre discussion du processus de débat porte non seulement sur la phase formelle des audiences publiques, mais aussi sur les étapes de concertation en amont et sur divers processus plus ou moins publicisés en aval. Ceci permet une réflexion d'ordre procédural plus riche qui considère la diversité des dispositifs dans une perspective de complémentarité. Pour chercher des effets du débat public sur le plan d'urbanisme, nous adoptons le parti de la congruence (Offner 1993), ce qui nous amène à une analyse de l'interaction entre des dynamiques contextuelles et des mobilisations des participants au débat. Certaines de ces congruences concordent avec des modifications au plan d'urbanisme. Notre étude propose aussi des implications du contexte particulier de la nouvelle ville de Montréal (avec la création des arrondissements) sur le contenu du débat public, sur certaines de ses manifestations procédurales ainsi que sur sa portée. Notre dernier chapitre montre que la dynamique du débat public en aval, dans la phase de mise en oeuvre du plan d'urbanisme, se déploie beaucoup plus dans les débats sur les grands projets que sur les mécanismes prévus à cette fin, qui comportent des embûches de par leur faible publicité et le caractère technique du processus réglementaire. Dans l'ensemble, notre étude met en lumière l'importance du contexte : autant le processus de débat que ses effets s'inscrivent dans des dynamiques contextuelles.

La perspective des scripts appliquée aux homicides et implications pour les enquêtes criminelles

Contexte et objectifs. Plusieurs études sur l’homicide ont été réalisées avec l’objectif d’épauler les policiers lors de leurs enquêtes. Le lien entre l’agresseur et la victime représente le principal déterminant des types de meurtres. L’utilité de ces études a toutefois été remise en question tant par les policiers que par la communauté scientifique. En combinant la perspective du script et l’approche dimensionnelle, le but du présent mémoire est d’améliorer les connaissances sur le processus de commission de l’homicide. Méthodologie. Différents scripts de l’homicide seront proposés afin de reconstituer le processus de commission du crime et de mieux comprendre les dynamiques expressives et instrumentales qui y sont rattachées. Les données utilisées dans le cadre de la recherche ont été recueillies auprès de 100 dossiers d’homicide de femmes et d’enfants répertoriés entre 1988 et 2011. Résultats. Les scripts permettent de dresser divers constats. Tout d’abord, lorsque la victime a subi d’importants sévices, le meurtrier est généralement un proche, indépendamment du motif initial de l’agresseur (p. ex. commettre un vol ou tout simplement tuer la victime). La sévérité des sévices dépend également de la présence d’armes sur les lieux du crime et du degré de résistance de la victime. Finalement, les scripts ont démontré que la nature de la relation entre la victime et l’agresseur influence le lieu où le meurtre prend place. Conclusion. Les résultats obtenus s’inscrivent dans une perspective différente en ce sens où, sans négliger la question de la personnalité, des variables contextuelles, hors du contrôle de l’agresseur, ont une incidence sur le niveau de sévices infligé à la victime. Le profile pourrait dès lors intégrer des aspects situationnels afin de pister les enquêteurs.

Assessment of construct validity and reliability of the inventory of masculinity and femininity in adolescents and young adults Colombian

This study evaluated the construct validity and reliability of Femininity and Masculinity Inventory-Imafe (Lara, 1993), and calculated standardized punctuations for Colombian teenagers and young adults. Participants were 1527 male and female, between 15 and 42. The general and scale reliability was evaluated through Alfa and Guttmann coefficients, and the factor analysis was used to estimate the construct validity. Standardized punctuations were obtained for gender, since there were statistically significant differences for sex in the six scales of the instrument. The inventory presented reliability values that oscillated between .76 and .88, and the factorial analysis showed three factors coherent with the factors found in its original validation. Correlacional inter-scales analysis and sex-differences were theoretically consistent.

Talassoterapia para pacientes com fibromialgia: ensaio clínico radômico

Fibromyalgia (FM) is a chronic rheumatic syndrome characterized by diffuse muscle-skeletal pain, and aerobic exercises represent a fundamental portion in therapeutic approach. Objective of this study was to evaluate the effectiveness of aerobic exercises accomplished in the water of the sea (thalassotherapy) for women with FM and to compare with exercises accomplished in the swimming pool, involving a multidisciplinary team, composed by rheumatologists, physical therapists, students of physical therapy and students of physical education. Forty six (46) women with age between 18 and 60 years with FM were randomized in 2 groups: a swimming pool group (23 patients) and a sea group (23 patients). 80th groups trained a week with the same program of aerobic conditioning 3 times (60 minutes each) for 12 weeks. Ali the patients were evaluated, before and immediately after treatment, with Visual Analogical Scale (VAS) for pain and fatigue, number of tending points, Fibromyalgia Impact Ouestionnaire (FIO), Short Form 36 Health Survey (SF-36), Pittsburgh Sleep Ouality Index (PSOI) and Beck Oepression Inventory (BOI). For statistical analysis, it was used paired-t test for analysis intra-group and non-paired test for inter-groups analysis, significance levei of p <0,05. Four patients, of each group, didn't complete the training programo Groups were homogeneous and they were compared in initial evaluation, except for BOI (p <0,05). Both groups presented statistically significant improvement for ali appraised parameters in the post-treatment compared with initial evaluation, there were reduction of intensity of pain and fatigue, number of tending points, better functional capacity (FIO), life quality (SF-36), quality of sleep (PSQI) and depression indexes (BOI). However, in comparison among the groups, group of sea (thalassotherapy) presented better results for ali parameters, however with statistically significant difference just only for depression indexes (BOI). At the end, it was observed that accomplishment of aerobic exercises in sea water or swimming pool was effective as part of treatment for patients with FM. However, exercise programs with thalassotherapy seems to bring more benefits, mainly related to emotional aspects, could be a therapeutic option of low cost for patients with FM in our area

Avaliação eletromiográfica de músculos inspiratórios em hemiparéticos / Eliete Moreira Colaço

The objective was measured by surface electromyography (EMGs), the activity of inspiratory muscles during incremental test in subjects with hemiparesis and show its correlation with the Functional Independence Measure (FIM). Were included in the study 32 individuals hemiparetics and 14 healthy as control group. We performed an evaluation of lung function and anthropometric data. The EMGs were performed during the incremental test with Threshold ® (15, 30, 45 and 60% of MIP) and during maximal inspiratory pressure (MIP). The electromyographic findings were calculated by the signal amplitude (RMS). All data were initially analyzed by Kolmogorov-Smirnov, the anthropometric characteristics of both groups were tested with the Levene and then intra-subject analysis (hemiparetic hemithorax and healthy hemithorax) and inter-group analysis (experimental group and control group) by paired and non-paired Student t tests and Pearson correlation. In intra-subject comparison was observed less activation (p <0.01) of the sternocleidomastoid muscle, scalene and diaphragm paretic side in both sexes - for the Threshold ® incremental test (15, 30, 45 and 60% of the MIP) and during maximal inspiratory pressure (MIP). In inter-group comparison, there was reduced activity in the diaphragm and the scalene, in hemiparetics males and females, respectivelly, during the same test. Our results demonstrate the existence of reduced electromyographic activity of inspiratory muscles in hemiparetics, including changes between different genders and suggests the need of further studies to assess the effects of specific training of inspiratory muscles.

Atividade eletromiográfica durante exercícios de propriocepção de tornozelo em apoio unipodal

Propriocepção refere-se à percepção dos mecanorreceptores para discriminar a posição do corpo e movimentos articulares, bem como tensões sobre os tendões na fase estática ou dinâmica da marcha. Objetivou-se avaliar por eletromiografia a ativação muscular do gastrocnêmio e tibial anterior em diferentes exercícios de propriocepção do tornozelo em apoio unipodal, comparando graus de dificuldade. Foram selecionados 54 voluntários, sedentários, destros, do sexo masculino (20-35 anos). Exercícios foram feitos no balancinho, prancha de equilíbrio, cama elástica e solo, à razão de três repetições de 15 segundos cada, com intervalo de 15 segundos entre as repetições. Ao final dos testes os voluntários indicaram a maior dificuldade. A atividade elétrica de ambos os músculos foi significativamente maior durante o teste no balancinho. No solo, ambos os músculos apresentaram menor atividade, mas apenas no gastrocnêmio essa diferença foi significativa. No exercício na prancha de equilíbrio e na cama elástica não se encontrou diferença quanto à ativação dos músculos. Na análise intermúsculo foi observada maior atividade do tibial anterior, exceto no balancinho. Assim, para o treino do apoio unipodal na aquisição do ganho proprioceptivo, o equipamento adotado deve ser escolhido com cuidado: no balancinho é maior o recrutamento dos músculos tibial anterior e gastrocnêmio, assim como é maior o grau de dificuldade para manutenção do equilíbrio.

Evaluation of the agreement by examiners according to classifications of third molars

Objectives. This study recorded and evaluated the intra-and inter-group agreement degree by different examiners for the classification of lower third molars according to both the Winter's and Pell & Gregory's systems. Study Design. An observational and cross-sectional study was realized with forty lower third molars analyzed from twenty digital panoramic radiographs. Four examiner groups (undergraduates, maxillofacial surgeons, oral radiologists and clinical dentists) from Aracaju, Sergipe, Brazil, classified them in relation to angulation, class and position. The variance test (ANOVA) was applied in the examiner findings with significance level of p<0.05 and confidence intervals of 95%. Results. Intra- and inter-group agreement was observed in Winter's classification system among all examiners. Pell & Gregory's classification system showed an average intra-group agreement and a statistical significant difference to position variable in inter-group analysis with greater disagreement to the clinical dentists group (p<0.05). Conclusions. High reproducibility was associated to Winter's classification, whereas the system proposed by Pell & Gregory did not demonstrate appropriate levels of reliability.

Myocardial injection of skeletal myoblasts impairs contractility of host cardiomyocytes

BACKGROUND: Mechanisms underlying improvement of myocardial contractile function after cell therapy as well as arrhythmic side effect remain poorly understood. We hypothesised that cell therapy might affect the mechanical properties of isolated host cardiomyocytes. METHODS: Two weeks after myocardial infarction (MI), rats were treated by intramyocardial myoblast injection (SkM, n=8), intramyocardial vehicle injection (Medium, n=6), or sham operation (Sham, n=7). Cardiac function was assessed by echocardiography. Cardiomyocytes were isolated in a modified Langendorff perfusion system, their contraction was measured by video-based inter-sarcomeric analysis. Data were compared with a control-group without myocardial infarction (Control, n=5). RESULTS: Three weeks post-treatment, ejection fraction (EF) further deteriorated in vehicle-injected and non-injected rats (respectively 40.7+/-11.4% to 33+/-5.5% and 41.8+/-8% to 33.5+/-8.3%), but was stabilised in SkM group (35.9+/-6% to 36.4+/-9.7%). Significant cell hypertrophy induced by MI was maintained after cell therapy. Single cell contraction (dL/dt(max)) decreased in SkM and vehicle groups compared to non-injected group as well as cell shortening and relaxation (dL/dt(min)) in vehicle group. A significantly increased predisposition for alternation of strong and weak contractions was observed in isolated cardiomyocytes of the SkM group. CONCLUSION: Our study provides the first evidence that injection of materials into the myocardium alters host cardiomyocytes contractile function independently of the global beneficial effect of the heart function. These findings may be important in understanding possible adverse effects.

Innovative Interventions with Alcohol Problems in Rural Areas: An Indian Experience and its Relevance to Rural America

Conventional interventions used to address the complex problems of substance abuse call for multifaceted approaches reflecting the diverse backgrounds of affected populations. In this paper the rural context is highlighted as an asset in contributing to sustainable recovery from alcohol problems. Against the background of comparing two international rural contexts and recognizing shared identities, a case is made for transfer of knowledge east to west. The success elements of a unique approach to intervention with problems associated with excessive drinking in rural areas of South India, based on the experiences of Community-Based Rehabilitation camps is described. Spanning two decades of systematic implementation, the camps utilize existing community resources for planning, execution, and follow-up of treatment while simultaneously creating greater awareness about alcohol abuse through community education. After a critical examination of prevailing treatment options for problem drinking in rural America, inter-country analysis reveals contextual similarities between rural America and rural South India based on community-orientation, cost-containment, and social capital formation with implications for rural social work intervention with alcohol problems in the United States.

The functional significance of EEG microstates-Associations with modalities of thinking

The momentary, global functional state of the brain is reflected by its electric field configuration. Cluster analytical approaches consistently extracted four head-surface brain electric field configurations that optimally explain the variance of their changes across time in spontaneous EEG recordings. These four configurations are referred to as EEG microstate classes A, B, C, and D and have been associated with verbal/phonological, visual, attention reorientation, and subjective interoceptive-autonomic processing, respectively. The present study tested these associations via an intra-individual and inter-individual analysis approach. The intra-individual approach tested the effect of task-induced increased modality-specific processing on EEG microstate parameters. The inter-individual approach tested the effect of personal modality-specific parameters on EEG microstate parameters. We obtained multichannel EEG from 61 healthy, right-handed, male students during four eyes-closed conditions: object-visualization, spatial-visualization, verbalization (6 runs each), and resting (7 runs). After each run, we assessed participants' degrees of object-visual, spatial-visual, and verbal thinking using subjective reports. Before and after the recording, we assessed modality-specific cognitive abilities and styles using nine cognitive tests and two questionnaires. The EEG of all participants, conditions, and runs was clustered into four classes of EEG microstates (A, B, C, and D). RMANOVAs, ANOVAs and post-hoc paired t-tests compared microstate parameters between conditions. TANOVAs compared microstate class topographies between conditions. Differences were localized using eLORETA. Pearson correlations assessed interrelationships between personal modality-specific parameters and EEG microstate parameters during no-task resting. As hypothesized, verbal as opposed to visual conditions consistently affected the duration, occurrence, and coverage of microstate classes A and B. Contrary to associations suggested by previous reports, parameters were increased for class A during visualization, and class B during verbalization. In line with previous reports, microstate D parameters were increased during no-task resting compared to the three internal, goal-directed tasks. Topographic differences between conditions concerned particular sub-regions of components of the metabolic default mode network. Modality-specific personal parameters did not consistently correlate with microstate parameters except verbal cognitive style which correlated negatively with microstate class A duration and positively with class C occurrence. This is the first study that aimed to induce EEG microstate class parameter changes based on their hypothesized functional significance. Beyond, the associations of microstate classes A and B with visual and verbal processing, respectively and microstate class D with interoceptive-autonomic processing, our results suggest that a finely-tuned interplay between all four EEG microstate classes is necessary for the continuous formation of visual and verbal thoughts, as well as interoceptive-autonomic processing. Our results point to the possibility that the EEG microstate classes may represent the head-surface measured activity of intra-cortical sources primarily exhibiting inhibitory functions. However, additional studies are needed to verify and elaborate on this hypothesis.
