The objective of this study was to investigate the effect of whole body vibration (WBV) exercise on oxidative stress markers in a group of women with fibromyalgia (FM) compared to a group of healthy women (CT). Twenty-one women diagnosed with FM and 21 age- and weight-matched healthy women were enrolled the study. Plasma oxidative stress markers (primary outcomes) were evaluated at rest and after WBV, and included thiobarbituric acid reactive substances (TBARS), iron reduction capacity (FRAP), superoxide dismutase antioxidant enzymes activity (SOD), and catalase (CAT). At rest, the FM group had higher TBARS (P<0.001) and FRAP (P<0.001), and lower CAT (P=0.005) compared to the CT. In the CT group, the WBV had no effect on TBARS (P=0.559) and FRAP (P=0.926), whereas it increased both SOD (P<0.001) and CAT (P<0.001). In the FM group, the WBV reduced TBARS (p <0.001), FRAP (P<0.001), and CAT (P=0.005), while it increased SOD (P=0.019). There was an interaction effect (moments vs groups) in the TBARS (effect size=1.34), FRAP (effect size=0.93), CAT (effect size=1.45), and SOD (effect size=1.44) (P<0.001). A single trial of WBV exercise improved all oxidant and antioxidant parameters towards a greater adaptation to the stress response in FM women.

The aims of this study were 1) to characterize the intensity of the vibration stimulation in women diagnosed with fibromyalgia (FM) compared to a control group of healthy women (HW) matched by age and anthropometric parameters, and 2) to investigate the effect of a single session of whole body vibration (WBV) on inflammatory responses. Levels of adipokines, soluble tumor necrosis factor receptors (sTNFr1, sTNFr2), and brain-derived neurotrophic factor (BDNF) were determined by enzyme-linked immunosorbent assay. Oxygen consumption (VO2) was estimated by a portable gas analysis system, heart rate (HR) was measured using a HR monitor, and perceived exertion (RPE) was evaluated using the Borg scale of perceived exertion. Acutely mild WBV increased VO2 and HR similarly in both groups. There was an interaction (disease vs vibration) in RPE (P=0.0078), showing a higher RPE in FM compared to HW at rest, which further increased in FM after acute WBV, whereas it remained unchanged in HW. In addition, there was an interaction (disease vs vibration) in plasma levels of adiponectin (P=0.0001), sTNFR1 (P=0.000001), sTNFR2 (P=0.0052), leptin (P=0.0007), resistin (P=0.0166), and BDNF (P=0.0179). In conclusion, a single acute session of mild and short WBV can improve the inflammatory status in patients with FM, reaching values close to those of matched HW at their basal status. The neuroendocrine mechanism seems to be an exercise-induced modulation towards greater adaptation to stress response in these patients.

RESUMO Considerando as perdas causadas por nematoides às diversas culturas, as rizobactérias se apresentam como uma alternativa para manejar esse patógenos. Assim, o objetivo deste trabalho foi avaliar in vitro a ação de 20 isolados de rizobactérias sobre a eclosão e a motilidade de juvenis de segundo estádio de Meloidogyne incognita e M. javanica e sobre a motilidade de Pratylenchus zeae. O experimento foi instalado em condições de laboratório e em delineamento inteiramente casuali-zado com quatro repetições, constituídas por uma câmara de eclosão cada. As avaliações foram realizadas a cada 72 horas. Após as avaliações observou-se que nenhum dos isolados avaliados influenciaram a eclosão de M. incognita, entretanto para M. javanica, os isolados FCAV 8 e FCAV 10 proporcionaram pronunciada ação ovicida. Entre os isolados testados sobre a motilidade dos nematoides-das-galha apenas os isolados de Bacillus amyloliquefaciens e B. subtillis evidenciaram potencial como agente do controle de juvenis de segundo estádio de M. javanica. Quando se avaliou a motilidade dos isolados sobre espécimes ativos de .. zeae, obsevou-se que os isolados FCAV 5, FCAV 7 e B. amyloliquefaciens exibiram potencial como agentes do controle biológico de .. zeae. Estes resultados confirmam que entre as rizobactérias podem ser encontrados agentes eficazes para o controle de nematoides.

ABSTRACT Considering the losses caused by nematodes to different host plant, rhizobacteria are presented as an alternative to to control uch pathogens. So the goal of this study was to evaluate in vitro the action of 20 isolates of rhizobacteria on hatching and motility of second stage juveniles of the Meloidogyne incognita and M. javanica and on the motility of Pratylenchus zeae. The experiment was conducted under laboratory conditions and in a completely randomize design with four replications, and each experimental plot was represented by a hatching chamber. Measurements were spaced every 72 hours. After the evaluations showed that the isolates not influenced the emergence of M. incognita. M. javanica entertaining for isolates FCAV FCAV 8 and 10 showed pronounced ovicidal action. Among the isolates tested on the motility root-knot nematode, only isolates of Bacillus amyloliquefaciens and B. subtilis showed potential as an agent for control of second stage juveniles of M. javanica. When we assessed the motility of isolated active on specimens of .. zeae isolates the FCAV 5, 7 and FCAV B.amyloliquefaciens exhibited potential as agents of biological control of .. zeae. These results confirm that among the rhizobacteria may be found effective agents for the control of nematodes.

Purpose. To demonstrate that interdisciplinary consensus improves the quality of work in the daily Intensive Care Unit (ICU), thus avoiding unnecessary routine x-ray examinations. We propose to monitor the results to maintain this low percentage of requests for x-rays. Design. Cycle of improvement in care quality. Setting. An 18-bed polyvalent ICU. Patients. A random sample of patients admitted in ICU during one month. Interventions. Establishment of basic agreed on protocol for routine chest portable x-ray (CPR) indications. After assessing the excessive amount of CPR according to those criteria, all intensivists accepted their application. Five years later, a second assessment of the degree of non-compliance was carried out and a monitoring schedule was established in order to avoid making unnecessary CPR again. Furthermore, a consensus between two intensivists was considered obligatory before a CPR request. Accordingly, all non-urgent CPR forms were signed by two intensivists, following the mentioned clinical criteria. Variable. Unsuitable portable chest x-ray indications. Results. In 1997, the overall non-compliance rate (ONCR) was 16.9%. After reducing it to 6.1%, lack of follow-up led to a non-compliance rate of 27.6% in 2003. Stable patients with uncomplicated ischemic heart disease (44.4% in 1997 and 53.8% in 2003) accounted for most of the inadequate ONCR indications. By using the consensus system for requesting routine portable x-rays that required the agreement of two intensivists achieved a reduction of non-compliance to 2.5% in 2003. The monitoring schedule designed has made it possible to follow the time of compliance degree and detect relaxation in the prescriptions. Conclusions. Unnecessary CPR can be easily reduced stressing our control in clinically stable patients. The requirement to justify a routine request (agreement between intensivists) makes it possible to decrease the number of CPRs. Periodic monitoring is the definitive tool for a successful improvement cycle.

Objetivo. Demostrar que el consenso interdisciplinar mejora la calidad del trabajo en la Unidad de Cuidados Intensivos (UCI), evitando exploraciones radiológicas rutinarias innecesarias, planteándose una monitorización de los resultados para mantener este bajo porcentaje de peticiones. Diseño. Ciclo de mejora de calidad asistencial. Ámbito. UCI de 18 camas de carácter polivalente. Pacientes. Pacientes ingresados en la UCI en el periodo de un mes, durante el cual se hizo un muestreo aleatorio sistemático. Intervenciones. Establecimiento de un protocolo consensuado de petición de radiografías de tórax portátiles (RTP) rutinarias. Tras comprobar el exceso de RTP siguiendo estos criterios, se acordó con todos los intensivistas su aplicación. Cinco años después se volvió a valorar el grado de incumplimiento y se incluyó un calendario de monitorizaciones para evitar la vuelta al exceso de solicitudes no justificadas. Además se introdujo un sistema de petición consensuado entre dos intensivistas, de manera que todas las RTP programadas para cada día se solicitaban por parte de dos intensivistas, atendiendo a los mencionados criterios. Variable. Peticiones que incumplen el protocolo de RTP programada. Resultados. En 1997, el grado global de incumplimiento era del 16,9%. Tras reducirlo al 6,1%, la falta de control posterior llevó a que en 2003 fuese del 27,6%. Los pacientes estables con cardiopatía isquémica (44,4% y 53,8% de todos los incumplimientos en esos dos años) constituyen el grueso de las indicaciones inadecuadas. El uso de un modelo de solicitud que requiere del consenso de dos intensivistas consiguió una reducción del incumplimiento al 2,5% en 2003. El calendario de monitorización ha permitido seguir en el tiempo el grado de cumplimiento y detectar la relajación en la prescripción. Conclusiones. Las RTP innecesarias pueden reducirse fácilmente incidiendo sobre los pacientes clínicamente estables. La obligación de justificar una petición rutinaria (consenso entre intensivistas) permite disminuir el número de peticiones de RTP. La monitorización periódica es la herramienta final para el éxito del ciclo de mejora.

The relationship between the irritable bowel syndrome (IBS) and food intolerance is not clear. We studied the cutaneous response to food antigens in 43 volunteers who were students and employees of the Faculty of Medicine of Universidade Federal Fluminense. Subjects were divided into 3 groups after evaluation for Roma II criteria for functional disease of the gastrointestinal tract: group I, 14 volunteers with IBS; group II, 15 volunteers with functional dyspepsia; group III, 14 volunteers without habitual gastrointestinal symptoms. The subjects were submitted to the skin prick test with 9 food antigen extracts, for a total of 387 skin tests (9 per volunteer). Of the 126 tests applied to group I, 24 (19.4%) were positive (a 3-mm wider papule than the negative control) and of the 135 tests applied to group II, 3 (2.3%) were positive. Of the 126 tests applied to group III, 6 (4%) were positive. The number of positive responses obtained in group I (IBS) differed significantly from the other 2 groups (P < 0.01). None of the volunteers with IBS reported intolerance to any isolated food. The higher reactivity to food antigens in group I compared to groups II and III suggests that intestinal permeability may be increased in patients with IBS.

Neste estudo investigamos a organização cromossômica de pacientes com retardo mental e/ou malformações congênitas, visando a avaliação de causas genéticas associadas a estes distúrbios. Os padrões de bandas GTG e CBG foram estudados a partir da cultura de linfócitos de sangue periférico, estimulados por fitohemaglutinina M. Dentre os 98 indivíduos portadores de retardo mental e/ou malformações congênitas analisados, diagnosticamos as seguintes síndromes: 12 casos de Down, dois de Edwards, um de Patau, cinco de Turner, dois de Klinefelter, um de "cri-du-chat", e um caso de translocação balanceada entre os cromossomos 13 e 14, um caso de cromossomo derivado e um outro de cromossomo marcador. Encontramos anomalias cromossômicas em 26% dos pacientes, das quais 82% eram alterações numéricas e o restante (18%) representou rearranjos estruturais. Este percentual significativo enfatiza o uso da cariotipagem de rotina em pacientes com retardo mental e/ou malformações congênitas.

We investigated the chromosomal constitution of patients with mental retardation and/or congenital malformations in order to determine genetic causes for such disturbances. The GTG and CBG banding patterns were studied using phytohemagglutinin M-stimulated lymphocytes cultured from peripheral blood. Among 98 individuals with mental retardation and/or congenital malformations who were analyzed there were 12 cases of Down's syndrome, two of Edward's syndrome, one of Patau's syndrome, five of Turner's syndrome, two of Klinefelter's syndrome, one of "cri-du-chat" syndrome, one case of a balanced translocation between chromosomes 13 and 14, one case of a derivative chromosome and one of a marker chromosome. We found abnormal chromosomes in 26% of the patients, 82% of which were numerical abnormalities, with the remaining 18% being structural variants. We conclude that patients with mental retardation and/or congenital malformations should be routinely karyotyped.
