Violência entre parceiros íntimos nos primeiros cinco meses de pós-parto em usuárias de unidades básicas de saúde do Rio de Janeiro

A Violência entre Parceiros Íntimos (VPI) tem sido reconhecida como um importante problema de saúde pública e um fator de risco para agravos a saúde de mulheres e crianças. Os serviços de saúde desempenham importante papel na detecção precoce da VPI, especialmente em momentos da vida nos quais se preconiza o atendimento sistematizado, como na gestação e primeira infância. Esta dissertação tem como objetivo principal estimar a probabilidade de ocorrência de Violência Física entre Parceiros Íntimos (VFPI) durante a gestação e/ou pós-parto em população atendida em Unidades Básicas de Saúde (UBS), segundo diferentes características sócio-econômicas e demográficas da clientela. Trata-se de um estudo transversal, realizado com usuárias de 5 UBS da cidade do Rio de Janeiro no ano de 2007. Foram entrevistadas 811 mães de crianças de até cinco meses de idade, que não possuíam nenhuma contra-indicação formal para a amamentação e que relataram ter tido pelo menos uma relação amorosa um mês ou mais durante a gestação ou no período do pós-parto. Condições socioeconômicas e demográficas e relativas aos hábitos de vida do casal foram consideradas como potenciais preditores de violência. Utilizou-se a versão em português da CTS2 para identificar as situações de VPI. A variável de desfecho foi analisada em três níveis: ausência de VFPI, presença de VFPI no período da gestação ou do pós-parto e presença de VFPI em ambos os períodos. Utilizou-se um modelo logito-multinomial para as projeções de prevalências segundo os descritores selecionados. Os fatores que mais aumentaram a probabilidade de ocorrência de violência durante a gestação e/ou nos primeiros cinco meses de vida da criança foram: idade materna < 20 anos, escolaridade materna inferior ao 2 grau completo, ter 2 ou mais filhos menores de cinco anos, tabagismo materno, uso inadequado de álcool pela mãe e/ou companheiro, uso de drogas pela mãe e/ou companheiro e percepção materna sobre a saúde do bebê aquém da esperada. Entre mães com todas estas características, a estimativa de prevalência projetada de VFPI na gestação e/ou no pós-parto chegou a 96,4%, sendo 59,4% a estimativa de ocorrência em apenas um dos dois períodos e 37% em ambos. Por outro lado, a probabilidade de ocorrência de VFPI cai a 3,6% em famílias sem estas características. Os resultados indicam que a presença de certas características da criança e de sua família aumenta enormemente a probabilidade de ocorrência de VFPI, devendo ser levadas em consideração ao se estabelecer estratégias de intervenção que visem à detecção precoce e uma efetiva intervenção.

A criança hospitalizada, seus direitos e as relações interpessoais no cuidado e tratamento: caminhos e descaminhos

O estudo objetivou compreender como se processa o respeito aos direitos da criança hospitalizada e sua família, pelo hospital e pelos profissionais de saúde. Procurou-se analisar as relações existentes entre os profissionais de saúde, a criança e sua família, no interior do hospital; como os profissionais percebem os direitos dessas crianças e de sua família, e como a própria família compreende os direitos dos seus filhos. Para isso, utilizou-se pesquisa qualitativa com enfoque etnográfico, tendo como técnicas a observação participante e entrevistas semiestruturadas Foram realizadas sete entrevistas com acompanhantes e onze com os profissionais de saúde, de um hospital pediátrico da cidade de Fortaleza CE, no ano de 2005 e 2006. A análise dos dados aconteceu após um processo de múltiplas leituras e estes foram interpretados com o referencial relativo aos temas elaborados. Surgiram quatro temáticas a partir da análise do material: a descoberta da doença na criança; a trajetória da criança hospitalizada; o conhecimento dos profissionais de saúde sobre os direitos da criança hospitalizada e as condições materiais de trabalho do profissional como um obstáculo na consecução desses direitos. Nas diversas conclusões, destacam-se: os múltiplos projetos de humanização existentes no hospital; a preocupação em manter um espaço destinado para a criança brincar; a criação de um espaço de higiene e alimentação para o acompanhante; o ambulatório da Cirurgia sem Medo, preparando a criança e família para a cirurgia, bem como a criação da fila única; a ampliação do horário de visita; a comunicação, muitas vezes deficiente, entre profissionais e acompanhantes; a pouca ou nenhuma orientação sobre normas e rotinas do hospital e sobre os direitos da criança e família no meio hospitalar; o limitado conhecimento sobre os direitos da criança hospitalizada, por alguns profissionais, desconhecendo os documentos importantes na área; e, finalmente, a falta de materiais de trabalho essenciais para a recuperação e bem-estar da criança hospitalizada como empecilhos a um cuidado pleno e de boa qualidade.

Pulmonary rehabilitation and follow-on services: a Northern Ireland survey

There should be a clear pathway through pulmonary rehabilitation and follow-on services. The aim of this survey was to determine the characteristics of the different components of the patient pathway, that is, pulmonary rehabilitation programs, ongoing exercise facilities, and support networks in Northern Ireland. Questionnaires were sent to current providers of pulmonary rehabilitation, providers of ongoing exercise, and support groups in Northern Ireland. Findings relating to the current status of pulmonary rehabilitation in Northern Ireland up to January 2007 are reported. There are currently 23 pulmonary rehabilitation programs in Northern Ireland. There appears to be a pathway through the short-term pulmonary rehabilitation program (6-8 weeks). Programs met standards for structure and format, except for the frequency of supervised exercise. Not all programs have links for the provision of ongoing exercise, but a range of exercise programs are available in leisure centers in Northern Ireland that include people with respiratory disease. There are 13 support groups for patients with respiratory disease in Northern Ireland and their function is diverse. Pulmonary rehabilitation is established in Northern Ireland, although not all patients are able to access these. Facilities for ongoing exercise and support groups are less developed. Improvements could be facilitated by better communication within the patient pathway and a strategic coordinated approach.

Analysis of temperature time-series: embedding dynamics into the MDS method

Global warming and the associated climate changes are being the subject of intensive research due to their major impact on social, economic and health aspects of the human life. Surface temperature time-series characterise Earth as a slow dynamics spatiotemporal system, evidencing long memory behaviour, typical of fractional order systems. Such phenomena are difficult to model and analyse, demanding for alternative approaches. This paper studies the complex correlations between global temperature time-series using the Multidimensional scaling (MDS) approach. MDS provides a graphical representation of the pattern of climatic similarities between regions around the globe. The similarities are quantified through two mathematical indices that correlate the monthly average temperatures observed in meteorological stations, over a given period of time. Furthermore, time dynamics is analysed by performing the MDS analysis over slices sampling the time series. MDS generates maps describing the stations’ locus in the perspective that, if they are perceived to be similar to each other, then they are placed on the map forming clusters. We show that MDS provides an intuitive and useful visual representation of the complex relationships that are present among temperature time-series, which are not perceived on traditional geographic maps. Moreover, MDS avoids sensitivity to the irregular distribution density of the meteorological stations.

Electrophysiological correlates of performance monitoring in middle and late adolescence

The ability to monitor and evaluate the consequences of ongoing behaviors and coordinate behavioral adjustments seems to rely on networks including the anterior cingulate cortex (ACC) and phasic changes in dopamine activity. Activity (and presumably functional maturation) of the ACC may be indirectly measured using the error-related negativity (ERN), an event-related potential (ERP) component that is hypothesized to reflect activity of the automatic response monitoring system. To date, no studies have examined the measurement reliability of the ERN as a trait-like measure of response monitoring, its development in mid- and late- adolescence as well as its relation to risk-taking and empathic ability, two traits linked to dopaminergic and ACC activity. Utilizing a large sample of 15- and 18-year-old males, the present study examined the test-retest reliability of the ERN, age-related changes in the ERN and other components of the ERP associated with error monitoring (the Pe and CRN), and the relations of the error-related ERP components to personality traits of risk propensity and empathy. Results indicated good test-retest reliability of the ERN providing important validation of the ERN as a stable and possibly trait-like electrophysiological correlate of performance monitoring. Ofthe three components, only the ERN was of greater amplitude for the older adolescents suggesting that its ACC network is functionally late to mature, due to either structural or neurochemical changes with age. Finally, the ERN was smaller for those with high risk propensity and low empathy, while other components associated with error monitoring were not, which suggests that poor ACe function may be associated with the desire to engage in risky behaviors and the ERN may be influenced by the extent of individuals' concern with the outcome of events.

Asymmetrical balance of power in preadolescents' mutual friendships

Dyadic friendShip' asymmetry was examined in relation to gender, friendship quality, and friendship status. Sixty-nine grade five children and their mutual, same-sex, friends participated in a laboratory session comprised ofvarious activities and completed questionnaires to identify mutual friends and evaluate friendship quality. Asymmetry of power was assessed observationally during an origami task. Variations in balance of power were evident in children's friendships. Boys' dyads had significantly greater levels of asymmetry than girls' dyads. Regardless of gender, asymmetry was associated with lower friendship quality, particularly as indexed by validation and caring and conflict resolution. Asymmetry was unrelated to differences in friendship status. Furthermore, relative individual power within the friendship was not related to individual perceptions offriendship quality. The implications ofthese findings in the theoretical and empirical literature were considered and suggestions for future research were made.

Attenuation of skeletal muscle FFA-induced insulin resistance by the polyphenol resveratrol. Elucidation of the mechanisms involved

Excess plasma free fatty acids (FFA) are correlated with insulin resistance and are a risk factor for the development of type 2 diabetes. In this study we examined the effect of the polyphenol resveratrol on FF A-induced insulin resistance in skeletal muscle cells and the mechanisms involved. Incubation of L6 myotubes with the FF A palmitate significantly decreased the insulin-stimulated glucqse uptake. Importantly, the effect of palmitate was ameliorated by resveratrol. Palmitate significantly increased serine phosphorylation of IRS..; 1 and reduced insulin-stimulated Akt phosphorylation, an effect that was abolished by resveratrol. We then investigated the effect of palmitate and resveratrol on the expression and phosphorylation of JNK, mTOR, p70-S6K, and AMPK kinases. The results demonstrated that our treatments had no effect on the expression of these proteins. However, palmitate increased the phosphorylation of mTOR and p70- S6K, whereas resveratrol abolished this effect and increased the phosphorylation of AMPK. Furthermore, all effects of resveratrol were abolished with sirtuin inhibitors, sirtinol and nicotinamide. These results indicate that resveratrol ameliorated FF A-induced insulin resistance by regulating mTOR and p70-S6K phosphorylation in skeletal muscle cells, through a mechanism involving sirtuins.

Relative importance of body composition, osteoporosis- related behaviours and socioeconomic status on bone SOS in adolescent females

The purpose of this study was to examine the associations between bone speed of sound (SOS) and body composition, osteoporosis-related health behaviours, and socioeconomic status (SES) in adolescent females. A total of 442 adolescent females in grades 9-11 participated. Anthropometric measures of height, body mass, and percent body fat were taken, and osteo-protective behaviours such as oral contraceptive use (OC), physical activity and daily calcium intake were evaluated using self-report questionnaires. Bone SOS was measured by transaxial quantitative ultrasound (QUS) at the distal radius and mid-tibia. The results suggest that fat mass is a significant negative predictor of tibial SOS, while lean mass is positively associated with radial SOS scores and calcium intake was positively associated with tibial SOS scores (p

The relationship between body mass index and breast cancer recurrence/progression and breast cancer-specific death

The aim of this study was to describe the nonlinear association between body mass index (BMI) and breast cancer outcomes and to determine whether BMI improves prediction of outcomes. A cohort of906 breast cancer patients diagnosed at Henry Ford Health System, Detroit (1985-1990) were studied. The median follow-up was 10 years. Multivariate logistic regression was used to model breast cancer recurrence/progression and breast cancer-specific death. Restricted cubic splines were used to model nonlinear effects. Receiver operator characteristic areas under the curves (ROC AUC) were used to evaluate prediction. BMI was nonlinearly associated with recurrence/progression and death (p= 0.0230 and 0.0101). Probability of outcomes increased with increase or decrease ofBMI away from 25. BMI splines were suggestive of improved prediction of death. The ROC AUCs for nested models with and without BMI were 0.8424 and 0.8331 (p= 0.08). I f causally associated, modifying patients BMI towards 25 may improve outcomes.

The effects of an acute bout of whole-body vibration on pulse wave velocity in individuals with SCI

Cardiovascular disease is a leading cause of mortality in the spinal cord injured (SCI) population. Reduced arterial compliance is a cardiovascular risk factor and whole body vibration (WBV) has be en shown to improve arterial compliance in able-bodied individuals. The study investigated the effect of an acute session ofWBV on arterial compliance as measured by pulse wave velocity (PWV). On separate days, arm, leg and aortic PWV were measured pre- and post- a 45 minute session of passive stance (PS) and WBV. The WBV was intermittent with a set frequency of 45Hz and amplitude of O.6mm. There was no condition by time effect when comparing PWV after WBV and PS. Following WBV, aortic (928.6±127.7 vs. 901.1±96.6cm/sec), leg (1035.2±113.8 vs.l099.8±114.2cm/sec) and arm PWV (1118.9±119.8 vs. 1181.1±124.4cm/s) did not change. As such, WBV did not reduce arterial compliance, however future research with protocol modifications is recommended.

Les Déterminants Génétiques de la Pharmacocinétique du Busulfan et les Résultats de la Transplantation

Le busulfan (Bu) est un composé clé de la phase de conditionnement chez les enfants subissant une transplantation des cellules souches hématopoïétiques (TCSH). Les différences inter-individuelles de la pharmacocinétique (PK) du Bu pourraient affecter son efficacité et sa toxicité. Le Bu est principalement métabolisé par la glutathion-S-transférase (GST). Nous avons étudié la relation des génotypes GSTA1, GSTM1 et GSTP1 avec la PK de la première dose de Bu et la relation avec les résultats de la TCSH chez 69 enfants recevant un régime de conditionnement myéloablatif. Le génotype GSTM1 nul a corrélé avec une exposition élevée du Bu et une faible clairance (CL) chez les patients âgés de 4 ans (p ≤ 0,04). Dans le respect du rôle fonctionnel suggéré d’haplotype GSTA1 *A2, il a été associé à des niveaux plus faibles de médicaments et des niveaux élevés de CL (p ≤ 0,03). L’effet Gène-dose a également été observé (p = ≤ 0,007). L’haplotype de GSTA1 était associé avec les résultats de la TCSH. Les porteurs de deux copies d’haplotype *A2 avaient une meilleure survie sans événement (p = 0,03). En revanche, les individus homozygotes pour haplotypes * B et *B1 ont un risque plus élevé d’atteindre la maladie veino-occlusive (MVO) (p = 0,009). Les individus porteurs de GSTM1 nul âgés de 4 ans possèdent un risque plus fréquent d’avoir la maladie du greffon contre l'hôte (GvHD) (p = 0,03). En conclusion, nous avons montré que les variantes génétiques de GST influencent la PK du BU et les résultats de la TCSH chez les enfants. Pour l'ajustement de la posologie, un modèle avec l'inclusion des facteurs génétiques et non génétiques devrait être évalué et validé dans une étude prospective.

Pandémie H1N1 : comparaison Canada-France des enfants hospitalisés en Soins Intensifs Pédiatriques Étude épidémiologique descriptive à partir de 2 cohortes nationales

Rationnel : La pandémie de grippe A(H1N1)pdm09 a induit un grand nombre d’hospitalisation d’enfants en soins intensifs pédiatriques (SIP). L’objectif de cette étude a été de comparer l’incidence et la mortalité des enfants admis en SIP durant l’automne 2009 entre le Canada et la France, deux pays qui diffèrent essentiellement par l’immunisation de la population contre ce virus (première vague en été et taux de couverture vaccinale supérieur à 50% au Canada ; pas de vague estivale et couverture vaccinale de 18% en France). Méthodes : Nous avons comparé deux cohortes nationales qui ont inclue tous les patients avec une infection A(H1N1)pdm09 documentée, admis en SIP au Canada et en France entre le 1er Octobre 2009 et le 31 janvier 2010. Résultats : Au Canada, 160 enfants (incidence=2,63/100000 enfants) en 6 semaines ont été hospitalisés en SIP comparé aux 125 enfants (incidence=1,15/100000 enfants) en 11 semaines en France (p<0,001). Le taux de vaccination avant l’admission était inférieur à 25% parmi les enfants en situation critique dans les deux pays. La gravité à l’admission en SIP et le taux de mortalité ont été similaires au Canada et en France (4,4% en France vs 6,5% au Canada, p=0,45, respectivement). Au Canada, la vaccination contre le virus H1N1pdm09 a été associée avec une diminution du recours à la ventilation invasive (Odd Ratio 0.30, intervalle de confiance à 95% [0,11-0,83], p=0,02). Au Canada comparé à la France, les durées médianes de séjour en SIP et de ventilation invasive ont été plus courtes (2,9 vs 3 jours, p=0,03 et 4 vs 6 jours, p=0,02, respectivement). Conclusion : Les enfants canadiens et français critiquement malades ont été beaucoup moins nombreux à recevoir le vaccin contre le virus influenza A (H1N1)pdm09 en comparaison avec l’ensemble des enfants dans ces deux populations. Au Canada, où la couverture vaccinale a été élevée, le risque d’avoir une détresse respiratoire sévère était moins important parmi les enfants en situation critique ayant été vaccinés avant l’admission.

Effets d'un programme d'exercices aérobie et en résistance, combinés, chez les patients atteints de fibrose kystique, intolérants au glucose ou diabétiques

La fibrose kystique (FK) est une des maladies rares la plus fréquente au Canada avec un âge médian de survie de 50.9 ans. Toutefois, l'amélioration de l’espérance de vie est associée à l'émergence de complications secondaires telles que le diabète associé à la FK (DAFK). Présent chez 25 à 40% des adultes, il augmente de 6 fois le risque de morbidité et de mortalité. Plusieurs études sur des populations atteintes de diabète de type 2 ont démontrés les bienfaits de programmes d’exercices combinés (aérobie et résistance) sur l’amélioration du contrôle glycémique. L’objectif de l’étude visait à déterminer si un programme d’exercices combinés permettait d’améliorer les anomalies de la tolérance au glucose et le contrôle glycémique chez les patients atteints de FK. Méthodologie: 18 adultes atteints de FK, sédentaires avec une intolérance au glucose ont été recrutés pour cette étude (8 hommes, 10 femmes, âge: 33 ± 9.4 ans, FEV1 71.5% pred ± 12.5, IMC 23.57 kg/m2 ± 3,4). Les participants ont été assignés au hasard à un groupe contrôle ou exercice. Les tests suivants ont été réalisés avant et après l’intervention : VO2max, HGPO, mesure de l'endurance et de la force musculaire, ainsi qu’un questionnaire sur la qualité de vie. Résultats: 14 participants ont complété le protocole. Les participants du groupe exercice ont amélioré leur valeur de glycémie plasmatique à la 2e heure de l’HGPO (-2.34 +/- 0.87 mmol/L; p <0.01; CI 99.22%), à la 1re heure de l’HGPO (-2.0 mmol/L; p<0.05) et ont présenté une réduction de 17.2% (p<0.05) de l’aire sous la courbe de glucose. Conclusion: Un programme d'exercices combinés améliore le contrôle glycémique chez les patients atteints de FK. Cette approche thérapeutique non-pharmacologique pourrait offrir une intervention ayant le potentiel de retarder l'apparition de DAFK.
