Tendências da frequência do consumo de feijão por meio de inquérito telefônico nas capitais brasileiras, 2006 a 2009

Analisar a tendência da frequência do consumo do feijão nos anos de 2006 a 2009 nas capitais brasileiras. Trata-se de uma série histórica utilizando a base de dados do Vigitel de todas as capitais brasileiras. O consumo de feijão foi descrito por meio da frequência relativa e a tendência foi avaliada utilizando-se regressão de Poisson. O consumo de feijão cinco ou mais vezes por semana variou de 71,85% (2006) a 65,79 (2009). Na maior faixa de frequência de consumo ao longo de todo o período estudado estão incluídas as capitais Goiânia, Belo Horizonte, Palmas, Cuiabá e Brasília. As pessoas com IMC na categoria adequado/baixo peso apresentaram as maiores frequências de consumo em relação aos indivíduos com sobrepeso e obesidade. Foi observada tendência significativa de redução do consumo regular de feijão segundo ano de realização da pesquisa, exceto para a categoria de idade entre os 45 e 54 anos. Ocorreu redução significativa da frequência do consumo do feijão pela população brasileira e a adoção de políticas de monitoramento e incentivo do consumo é necessária em função dos benefícios apresentados pela leguminosa.

Outlining new frontiers for the comprehension of obsessive-compulsive disorder: a review of its relationship with fear and anxiety

Anxiety is an important component of the psychopathology of the obsessive-compulsive disorder (OCD). So far, most interventions that have proven to be effective for treating OCD are similar to those developed for other anxiety disorders. However, neurobiological studies of OCD came to conclusions that are not always compatible with those previously associated with other anxiety disorders. OBJECTIVES: The aim of this study is to review the degree of overlap between OCD and other anxiety disorders phenomenology and pathophysiology to support the rationale that guides research in this field. RESULTS: Clues about the neurocircuits involved in the manifestation of anxiety disorders have been obtained through the study of animal anxiety models, and structural and functional neuroimaging in humans. These investigations suggest that in OCD, in addition to dysfunction in cortico-striatal pathways, the functioning of an alternative neurocircuitry, which involves amygdalo-cortical interactions and participates in fear conditioning and extinction processes, may be impaired. CONCLUSION: It is likely that anxiety is a relevant dimension of OCD that impacts on other features of this disorder. Therefore, future studies may benefit from the investigation of the expression of fear and anxiety by OCD patients according to their type of obsessions and compulsions, age of OCD onset, comorbidities, and patterns of treatment response.

Application of H∞ theory to a 6 DOF flight simulator motion base

The purpose of this study is to apply inverse dynamics control for a six degree of freedom flight simulator motion system. Imperfect compensation of the inverse dynamic control is intentionally introduced in order to simplify the implementation of this approach. The control strategy is applied in the outer loop of the inverse dynamic control to counteract the effects of imperfect compensation. The control strategy is designed using H∞ theory. Forward and inverse kinematics and full dynamic model of a six degrees of freedom motion base driven by electromechanical actuators are briefly presented. Describing function, acceleration step response and some maneuvers computed from the washout filter were used to evaluate the performance of the controllers.

Models for capacitated lot-sizing problem with backlogging, setup carryover and crossover

Setup operations are significant in some production environments. It is mandatory that their production plans consider some features, as setup state conservation across periods through setup carryover and crossover. The modelling of setup crossover allows more flexible decisions and is essential for problems with long setup times. This paper proposes two models for the capacitated lot-sizing problem with backlogging and setup carryover and crossover. The first is in line with other models from the literature, whereas the second considers a disaggregated setup variable, which tracks the starting and completion times of the setup operation. This innovative approach permits a more compact formulation. Computational results show that the proposed models have outperformed other state-of-the-art formulation.

Perceived neighborhood problems: multilevel analysis to evaluate psychometric properties in a Southern adult Brazilian population

Abstract Background Physical attributes of the places in which people live, as well as their perceptions of them, may be important health determinants. The perception of place in which people dwell may impact on individual health and may be a more telling indicator for individual health than objective neighborhood characteristics. This paper aims to evaluate psychometric and ecometric properties of a scale on the perceptions of neighborhood problems in adults from Florianopolis, Southern Brazil. Methods Individual, census tract level (per capita monthly familiar income) and neighborhood problems perception (physical and social disorders) variables were investigated. Multilevel models (items nested within persons, persons nested within neighborhoods) were run to assess ecometric properties of variables assessing neighborhood problems. Results The response rate was 85.3%, (1,720 adults). Participants were distributed in 63 census tracts. Two scales were identified using 16 items: Physical Problems and Social Disorder. The ecometric properties of the scales satisfactory: 0.24 to 0.28 for the intra-class correlation and 0.94 to 0.96 for reliability. Higher values on the scales of problems in the physical and social domains were associated with younger age, more length of time residing in the same neighborhood and lower census tract income level. Conclusions The findings support the usefulness of these scales to measure physical and social disorder problems in neighborhoods.

Clinical predictors of long-term outcome in obsessive-compulsive disorder

Background: The purpose of this study was to investigate demographic and clinical factors associated with the long-term outcome of obsessive-compulsive disorder (OCD). Methods: A hundred ninety-six previously untreated patients with DSM-IV criteria OCD completed a 12-week randomized open trial of group cognitive-behavioral therapy (GCBT) or fluoxetine, followed by 21 months of individualized, uncontrolled treatment, according to international guidelines for OCD treatment. OCD severity was assessed using the Yale–Brown Obsessive-Compulsive Scale (Y-BOCS) at different times over the follow-up period. Demographics and several clinical variables were assessed at baseline. Results: Fifty percent of subjects improved at least 35% from baseline, and 21.3% responded fully (final Y-BOCS score < or = 8). Worse prognosis was associated with earlier age at onset of OCD (P = 0.045), longer duration of illness (P = 0.001) presence of at least one comorbid psychiatric disorder (P = 0.001), comorbidity with a mood disorder (P = 0.002), higher baseline Beck-Depression scores (P = 0.011), positive family history of tics (P = 0.008), and positive family history of anxiety disorders (P = 0.008). Type of initial treatment was not associated with long-term outcome. After correction for multiple testing, the presence of at least one comorbid disorder, the presence of a depressive disorder, and duration of OCD remained significant. Conclusions: Patients under cognitive-behavioral or pharmacological treatment improved continuously in the long run, regardless of initial treatment modality or degree of early response, suggesting that OCD patients benefit from continuous treatment. Psychiatric comorbidity, especially depressive disorders, may impair the long-term outcome of OCD patients.

The performance of four molecular methods for the laboratory diagnosis of congenital toxoplasmosis in amniotic fluid samples

Introduction Toxoplasmosis may be life-threatening in fetuses and in immune-deficient patients. Conventional laboratory diagnosis of toxoplasmosis is based on the presence of IgM and IgG anti-Toxoplasma gondii antibodies; however, molecular techniques have emerged as alternative tools due to their increased sensitivity. The aim of this study was to compare the performance of 4 PCR-based methods for the laboratory diagnosis of toxoplasmosis. One hundred pregnant women who seroconverted during pregnancy were included in the study. The definition of cases was based on a 12-month follow-up of the infants. Methods Amniotic fluid samples were submitted to DNA extraction and amplification by the following 4 Toxoplasma techniques performed with parasite B1 gene primers: conventional PCR, nested-PCR, multiplex-nested-PCR, and real-time PCR. Seven parameters were analyzed, sensitivity (Se), specificity (Sp), positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (PLR), negative likelihood ratio (NLR) and efficiency (Ef). Results Fifty-nine of the 100 infants had toxoplasmosis; 42 (71.2%) had IgM antibodies at birth but were asymptomatic, and the remaining 17 cases had non-detectable IgM antibodies but high IgG antibody titers that were associated with retinochoroiditis in 8 (13.5%) cases, abnormal cranial ultrasound in 5 (8.5%) cases, and signs/symptoms suggestive of infection in 4 (6.8%) cases. The conventional PCR assay detected 50 cases (9 false-negatives), nested-PCR detected 58 cases (1 false-negative and 4 false-positives), multiplex-nested-PCR detected 57 cases (2 false-negatives), and real-time-PCR detected 58 cases (1 false-negative). Conclusions The real-time PCR assay was the best-performing technique based on the parameters of Se (98.3%), Sp (100%), PPV (100%), NPV (97.6%), PLR (â^ž), NLR (0.017), and Ef (99%).

Contribuição da inclusão de polpa cítrica e casca de soja para a qualidade da silagem de resíduo úmido de cervejaria

Com o objetivo de avaliar a produção da silagem e o uso de aditivos no processo de ensilagem do resíduo úmido de cervejaria, foram realizados 5 tratamentos: controle (C: ensilagem de 100% de resíduo úmido de cervejaria); PC15 (15% de polpa cítrica); PC30 (30% de polpa cítrica); CS15 (15% de casca de soja); CS30 (30% de casca de soja) – com base na matéria fresca do resíduo de cervejaria. As silagens foram confeccionadas em baldes plásticos com 252mm de altura e 245mm de diâmetro (0,06174m³), e amostras foram coletadas para análises bromatológicas, pH, nitrogênio amoniacal, digestão in vitro de matéria seca, ácidos orgânicos e perfil microbiológico. Os resultados foram analisados pelo programa computacional Statistical Analysis System (Statistical..., 1985), sendo verificada a normalidade dos resíduos pelo Teste de Shapiro-Wilk (PROC UNIVARIATE), e as variâncias, pelo Teste de Hartley. Os efeitos dos níveis de adição foram separados por meio de contrastes polinomiais utilizando o nível de significância de 5%. Houve aumento do teor de matéria seca, carboidratos solúveis, ácido lático, digestão in vitro de matéria seca, da população de bactérias ácido láticas e redução do pH, ácido butírico, propiônico e nitrogênio amoniacal a partir das inclusões de polpa cítrica e casca de soja, sendo os melhores resultados encontrados para o tratamento com inclusão de 30% de polpa cítrica (P<0,05). A ensilagem do bagaço de malte por si só é uma alternativa para o produtor rural como suporte alimentar e confecção de silagem de qualidade que pode ser incrementada com o uso de aditivos a serem avaliados de acordo com a relação custo-benefício para eficiência da produção

La canzone tradotta. Uno scorcio sul samba brasiliano attraverso il sottotitolaggio del documentario "Roda"

Tradurre testi di brani musicali è il fulcro di questo lavoro. Il contesto è il Brasile, la città di Belo Horizonte, una realtà periferica e un gruppo di cantanti e musicisti di samba. Questo è il quadro ritratto del documentario preso in esame “Roda” di Carla Maia e Raquel Junquera e del quale si propone qui la sua traduzione integrale dal portoghese all'italiano per il sottotitolaggio (per il quale si sono seguiti i riferimenti del libro “Teoría y práctica de la subtitulación: Inglés-Español” di Jorge Díaz Cintas). Dopo una panoramica generale del samba come stile musicale e fenomeno culturale, in questa tesi si affrontano tematiche e complessità legate alla traduzione di canzoni e del genere filmico del documentario proponendo esempi specifici e spunti teorici. Inoltre, vengono inclusi argomenti quali registro, fraseologia e umorismo. Sono infine illustrati i metodi e gli strumenti usati per la realizzazione di questo lavoro.

Suitability of low-dosage oxytocin treatment to induce milk ejection in dairy cows

Chronic use of high oxytocin (OT) dosages can cause a reduced response to endogenous OT. In this study the OT dosages used in the milking practice of 82 dairy cow farms were recorded. The OT dosages per cow used were high, especially when injected i.m. (23+/-2 IU) compared with i.v. (7+/-1 IU). In addition, the minimum OT dosages needed to obtain normal milk removal in cows with disturbed milk ejection were investigated. Seventeen cows routinely treated with OT during milking (group T) and 17 cows without previous OT treatment were used (group C). After cessation of spontaneous milk flow, both T and C groups were injected i.v. with a low dosage of OT (0.2 or 0.5 IU/cow). The time from injection until cessation of the OT-induced milk flow was recorded (response phase). The response phase and the amounts of removed milk by effect of the OT injection increased with increasing OT dosage. Values for 0.2 and 0.5 IU/cow of OT injected i.v. were (response phase and amount of milk removed) 198+/-27 and 302+/-18s and 3.4+/-0.7 kg and 6.5+/-1.3 kg, respectively, for the C group, and 157+/-15 and 221+/-16s and 3.2+/-0.5 and 5.5+/-1.0 kg, respectively, for the T group. Within 20 min of the OT injection, plasma concentrations returned to basal levels. The threshold OT concentration at cessation of milk flow after injection of 0.2 or 0.5 IU/cow of OT was calculated based on the OT plasma half-life. The threshold increased with increasing dosages of OT and was higher in group T (8+/-1 and 14+/-1 pg/mL for 0.2 and 0.5 IU/cow, respectively) than in group C (7+/-1 and 11+/-1 pg/mL for 0.2 and 0.5 IU/cow, respectively). In conclusion, desensitization of the udder toward OT occurs when the udder is exposed to elevated OT plasma concentrations, both short-term during the actual milking and long-term due to chronic high-dosage OT treatment. However, low-dosage OT treatments to induce normal milk removal can minimize the observed side effects.
