Manejo de lesiones abiertas del plexo braquial con compromiso vascular concomitante. Revisión sistemática de la literatura

El manejo de las lesiones de plejo braquial ha sido ampliamente discutido e investigado, especialmente en las lesiones cerradas por tracción. Las lesiones abiertas con compromiso vascular, muchas veces comprometen la viabilidad de la extremidad o la vida del paciente; son de difícil manejo con prioridades distintas, tiempos de establecimiento de los procedimientos que varían respecto a los hallazgos con resultados funcionales pobres por el diagnostico tardío de la lesión nerviosa. Se plantean interrogantes desde el punto de vista vascular y de la lesión nerviosa. se realiza una revisión sistemática de la literatura, encontrando puntos importantes con respecto a la exploración, el momento de la reparación nerviosa pero sin establecer resultados funcionales claros ante la deficiencia metodológica de los estudios encontrados.

Um processo de autogestão: crônica e crítica de uma experiência em psicologia institucional

O presente trabalho tem por objetivo fazer uma análise dos dados levantados pelo Departamento de Psicologia, de um Estabelecimento Escolar, que utiliza conceitos de Psicologia Institucional, desde a implantação (agosto de 1974), até o presente momento, (julho de 1978) pois seu desenvolvimento continua acontecendo. Durante este período os objetivos principais centralizaram-se em procurar investigar todas às formas do "latente" institucional a fim de desinvestir e desmontar as estruturas repressivas que pudessem estar impedindo o crescimento do estabelecimento no sentido de proporcionar um trabalho autogestivo com um máximo de liberdade e espírito crítico. Para que então, estes conceitos sejam aplicados tem-se praticado, de forma permanente, a metodologia da Análise Institucional, pois é através dela que se pretende realizar uma abordagem aos diferentes aspectos inconscientes e/ou desconhecidos da estrutura psico-socio-comunicacional do Estabelecimento. Tenta-se através de contextos técnicos vivenciais (grupos, etc) fazer com que os diferentes quadros do estabelecimento elaboremos aspectos acima mencionados, instrumentando-os para controlar as posições contraditórias, que ocupam, simultaneamente, todos os seus integrantes, por serem servidores do instituído e também encarregados de uma função instituinte.

Effects of different dietary lipid sources on the survival, growth, and fatty acid composition of South American catfish, Pseudoplatystoma fasciatum, Surubim, juveniles

The present study examines the effect of four semi-purified diets (casein-gelatin based) where the source of fatty acids was free (esterified) oleic acid and linoleic acid (LA) (LOA diet), linseed and olive oil (predominantly LA and linolenic acid) (LO diet), cod liver oil (rich in highly unsaturated fatty acids) (CLO diet), and soybean lecithin (phospholipids; mostly LA) (LE diet) on the growth of juvenile South American catfish (surubim, Pseudoplatystoma fasciatum, Pimelodidae) (0.98 +/- 0.04 g individual weight). Fish were fed at a restricted-readjusted feeding rate for 8 wk. At the end of the experiment, LE-diet-fed fish grew significantly larger than those of the other three groups (P < 0.05). Considerable cannibalism was observed in all the treatments. It is suggested that the quantitative growth performance may possibly change under other conditions, with less or no cannibalism. Survival did not differ significantly among the fish fed four different diets. Muscle and liver lipid contents did not vary among dietary treatments (P > 0.05), but whole-body lipid concentrations were affected by dietary treatments. Fish fed LE diet contained significantly lower lipid level than those fed three other diets (P < 0.05). Muscle and liver fatty acid profiles reflected dietary fatty acid composition. Arachidonic acid level was significantly higher in muscle and liver of fish fed LOA and LE diets than in those fed LO and CLO diets. The results suggest that the efficiency of elongation and desaturation of 18C fatty acids depends on the dietary lipid source, and South American catfish has considerable capacity to transform linoleate to arachidonate.

Combination of Tevatron Searches for the Standard Model Higgs Boson in the W+W- Decay Mode

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)

Combined Tevatron upper limit on gg -> H -> W+W- and constraints on the Higgs boson mass in fourth-generation fermion models

We combine results from searches by the CDF and D0 collaborations for a standard model Higgs boson (H) in the process gg -> H -> W+W- in p (p) over bar collisions at the Fermilab Tevatron Collider at root s = 1.96 TeV. With 4.8 fb(-1) of integrated luminosity analyzed at CDF and 5.4 fb(-1) at D0, the 95% confidence level upper limit on sigma(gg -> H) x B(H -> W+W-) is 1.75 pb at m(H) = 120 GeV, 0.38 pb at m(H) = 165 GeV, and 0.83 pb at m(H) = 200 GeV. Assuming the presence of a fourth sequential generation of fermions with large masses, we exclude at the 95% confidence level a standard-model-like Higgs boson with a mass between 131 and 204 GeV.

Nível de maturidade e comparação dos PDPs de produtos automotivos

O desenvolvimento de novos produtos, que atendam às necessidades do mercado consumidor, é atividade estratégica para sustentabilidade das organizações. O objetivo deste artigo é comparar e avaliar o nível de maturidade desses processos em duas montadoras de veículos instaladas na região Sul Fluminense do País. São discutidas algumas características dos processos, expõe-se o modelo de avaliação, baseado nos critérios do CMMI (Capability Maturity Model Integration), e são apresentados os resultados de pesquisa que investigou o nível de maturidade junto a 47 representantes das empresas estudadas. Como resultado, foi possível identificar lacunas na estruturação dos PDP's, com diversas práticas e ferramentas usadas de forma isolada e não integradas, havendo campo suficiente - no entendimento dos próprios executivos - para serem aprimorados e refinados, o que permitiria torná-los mais completos, abrangentes e potentes para alavancar os resultados de mercado e financeiros das próprias organizações.

Towards a post-traumatic subtype of obsessive-compulsive disorder

We evaluated whether traumatic events are associated with a distinctive pattern of socio-demographic and clinical features of obsessive-compulsive disorder (OCD). We compared socio-demographic and clinical features of 106 patients developing OCD after post-traumatic stress disorder (PTSD; termed post-traumatic OCD), 41 patients developing OCD before PTSD (pre-traumatic OCD), and 810 OCD patients without any history of PTSD (non-traumatic OCD) using multinomial logistic regression analysis. A later age at onset of OCD, self-mutilation disorder, history of suicide plans, panic disorder with agoraphobia, and compulsive buying disorder were independently related to post-traumatic OCD. In contrast, earlier age at OCD onset, alcohol-related disorders, contamination-washing symptoms, and self-mutilation disorder were all independently associated with pre-traumatic OCD. In addition, patients with post-traumatic OCD without a previous history of obsessive-compulsive symptoms (OCS) showed lower educational levels, greater rates of contamination-washing symptoms, and more severe miscellaneous symptoms as compared to post-traumatic OCD patients with a history of OCS. © 2011 Elsevier Ltd.

Combination of CDF and D0 measurements of the W boson helicity in top quark decays

We report the combination of recent measurements of the helicity of the W boson from top quark decay by the CDF and D0 collaborations, based on data samples corresponding to integrated luminosities of 2.7-5.4fb -1 of pp̄ collisions collected during Run II of the Fermilab Tevatron collider. Combining measurements that simultaneously determine the fractions of W bosons with longitudinal (f 0) and right-handed (f +) helicities, we find f 0=0.722±0.081[±0.062(stat)±0.052(syst)] and f +=-0.033±0.046[±0.034(stat)±0.031(syst)]. Combining measurements where one of the helicity fractions is fixed to the value expected in the standard model, we find f 0=0.682±0. 057[±0.035(stat)±0.046(syst)] for fixed f + and f +=-0.015±0.035[±0.018(stat)±0.030(syst)] for fixed f 0. The results are consistent with standard model expectations. © 2012 American Physical Society.

Impulsive compulsivity in obsessive-compulsive disorder: A phenotypic marker of patients with poor clinical outcome

Although traditionally obsessive-compulsive disorder (OCD) and impulse control disorders (ICD) have represented opposing ends of a continuum, recent research has demonstrated a frequent co-occurrence of impulsive and compulsive behaviours, which may contribute to a worse clinical picture of some psychiatric disorders. We hypothesize that individuals with 'impulsive' OCD as characterized by poor insight, low resistance, and reduced control towards their compulsions will have a deteriorative course, greater severity of hoarding and/or symmetry/ordering symptoms, and comorbid ICD and/or substance use disorders (SUD). The sample consisted of 869 individuals with a minimum score of 16 on the Yale-Brown Obsessive Compulsive Scale (Y-BOCS). Of these, 65 had poor insight, low resistance, and reduced control towards compulsions ('poor IRC') and 444 had preserved insight, greater resistance and better control over compulsions ('good IRC'). These two groups were compared on a number of clinical and demographic variables. Individuals with poor IRC were significantly more likely to have a deteriorative course (p < 0.001), longer duration of obsessions (p = 0.017), greater severity of symmetry/ordering (p < 0.001), contamination/cleaning (p < 0.001) and hoarding (p = 0.002) symptoms, and comorbid intermittent explosive disorder (p = 0.026), trichotillomania (p = 0.014) and compulsive buying (p = 0.040). Regression analysis revealed that duration of obsessions (p = 0.037) and hoarding severity (p = 0.005) were significant predictors of poor IRC. In the absence of specific measures for impulsivity in OCD, the study highlights the utility of simple measures such as insight, resistance and control over compulsions as a phenotypic marker of a subgroup of OCD with impulsive features demonstrating poor clinical outcome. © 2012 Elsevier Ltd.
