Associação entre excesso de peso e consumo de feijão em adultos

OBJETIVO: Avaliar associação entre excesso de peso e consumo de feijão em adultos. MÉTODOS: O estudo constou de indivíduos adultos (>18 anos), moradores em Belém (PA), em 2005. A amostragem foi realizada por sorteio de residências com telefone fixo e de um morador adulto de cada casa sorteada. A variável desfecho foi excesso de peso, a variável explanatória consumo de feijão e as variáveis de controle foram idade, escolaridade e situação conjugal, além de atividade física no lazer e hábitos alimentares de risco. A análise dos dados foi feita pelo teste do qui-quadrado e por regressão logística. RESULTADOS: Foram avaliados 2 352 indivíduos (39,8% do sexo masculino). O excesso de peso atingiu mais os homens, 49,3%, do que as mulheres, 34,0% (p<0,001). A prevalência de excesso de peso apresentou associação direta com idade em ambos os sexos e com escolaridade para homens, para as mulheres a associação com a escolaridade foi inversa. A variável referente ao consumo alimentar que melhor se associou com excesso de peso foi o consumo de feijão. Após ajuste para as demais variáveis, o risco de excesso de peso foi cerca de 1,4 vez maior para os homens que consomem feijão menos do que cinco vezes na semana, porém o inverso para as mulheres. CONCLUSÃO: Os resultados indicam a necessidade de estudos mais controlados para melhor entendimento da associação entre consumo de feijão e excesso de peso.

Accurate adjustment of feed formulation for broiler chickens on performance and lipid composition of meat

Most consumers consider the fat of chicken meat undesirable for a healthy diet, due to the high levels of saturated fatty acids and cholesterol. The purpose of this experiment was to investigate the influence of changes in dietary metabolizable energy level, associated with a proportional nutrient density variation, on broiler chickens performance and on the lipid composition of meat. Males and females Cobb 500 broilers were evaluated separately. Performance evaluation followed a completely randomized design with factorial 6x3 arrangement - six energy levels (2,800, 2,900, 3,000, 3,100, 3,200 and 3,300 kcal/kg) and three slaughter ages (42, 49 and 56 days). Response surface methodology was used to establish a mathematical model to explain live weight, feed intake and feed conversion behavior. Total lipids and cholesterol were determined in skinned breast meat and in thigh meat, with and without skin. For lipid composition analysis, a 3x3x2 factorial arrangement in a completely randomized design - three ration’s metabolizable energy levels (2,800, 3,000 and 3,300 kcal/kg), three slaughter ages (42, 49 and 56 days) and two sexes - was used. The reduction in the diet metabolizable energy up to close to 3,000 kcal/kg did not affect live weight but, below this value, the live weight decreased. Feed intake was lower when the dietary energy level was higher. Feed conversion was favored in a direct proportion to the increase of the energy level of the diet. The performance of all birds was within the range considered appropriate for the lineage. Breast meat had less total lipids and cholesterol than thigh meat. Thigh with skin had more than the double of total lipids of skinned thigh, but the cholesterol content did not differ with the removal of the skin, suggesting that cholesterol content is not associated with the subcutaneous fat. Intramuscular fat content was lower in the meat from birds fed diets with lower energy level. These results may help to define the most appropriate nutritional management. Despite the decrease in bird’s productive performance, the restriction of energy in broiler chickens feed may be a viable alternative, if the consumers are willing to pay more for meat with less fat.

Trade Adjustment Assistance for Farmers Available 2010

The American Recovery and Reinvestment Act (ARRA) of 2009 has re-authorized and modified the Trade Adjustment Assistance for Farmers program. The statute authorizes an appropriation of not more than $90 million per year for the next three fiscal years. The TAA for Farmers program helps producers of raw agricultural commodities (farmers, ranchers or fishermen) who have experienced significant declines in price or production, adjust to the changing economic environment brought on by import competition. The program provides benefits to eligible producers in the form of educational assistance, as well as up to $12,000 per producer in cash benefits to help create and implement business adjustment plans.

Postural adjustment after an unexpected perturbation in children with haemophilia

. Children with haemophilia often bleed inside joints and muscles, which may impair postural adjustments. These postural adjustments are necessary to control postural balance during daily activities. The inability to quickly recover postural balance could elevate the risk of bleeding. To determine whether children with haemophilia have impaired postural adjustment after an unexpected perturbation compared with healthy children. Twenty children with haemophilia comprised the haemophilic group (HG), and 20 healthy, age-paired children comprised the control group (CG). Subjects stood on a force plate, and 4% of the subjects body weight was applied via a pulley system to a belt around the subjects trunks. The centre of pressure (COP) displacement was measured after the weight was unexpectedly released to produce a controlled postural perturbation followed by postural adjustment to recover balance. The subjects postural adjustments in eight subsequent intervals of 1 s (t1t8), beginning with the moment of weight removal, were compared among intervals and between groups. The applied perturbation magnitudes were the same for both groups, and no difference was observed between the groups in t1. However, the COP displacement in t2 in the HG was significantly higher than in the CG. No differences were observed between the groups in the other intervals. Within-group analysis showed that the COP was higher in t2 than in t4 (P = 0.016), t5 (P = 0.001) and t8 (P = 0.050) in the HG. No differences were observed among intervals in the CG. Children with haemophilia demonstrated differences in postural adjustment while undergoing unexpected balance perturbations when compared with healthily children.

The effects of infertility on the spouses' relationship

The present study investigated the effects of infertility on the spouses' relationship, with the objectives to describe the profile of the studied population, and analyze the effects of infertility on their emotional, sexual and marital life. To do this, a cross-sectional and prospective study was performed in a specialist institution. The sample consisted of 50 infertile couples with a mean of six years of infertility. The women manifested negative feelings in view of the infertility, while the men assumed an attitude of support. The effects on the couples' sexual life were more pronounced in women, and the infertility treatment resulted in positive changes for both spouses. No differences were found regarding the effects of infertility between the women who had undergone more than one treatment and those undergoing treatment for the first time; between the men there were differences in the emotional aspect ( frustration and relief) and in the marital relationship ( strengthening and maturing).

Robust and optimal adjustment of Power System Stabilizers through Linear Matrix Inequalities

This work presents the application of Linear Matrix Inequalities to the robust and optimal adjustment of Power System Stabilizers with pre-defined structure. Results of some tests show that gain and zeros adjustments are sufficient to guarantee robust stability and performance with respect to various operating points. Making use of the flexible structure of LMI's, we propose an algorithm that minimizes the norm of the controllers gain matrix while it guarantees the damping factor specified for the closed loop system, always using a controller with flexible structure. The technique used here is the pole placement, whose objective is to place the poles of the closed loop system in a specific region of the complex plane. Results of tests with a nine-machine system are presented and discussed, in order to validate the algorithm proposed. (C) 2012 Elsevier Ltd. All rights reserved.

Lumpiness, capital adjustment costs and investment dynamics

Aggregate investment in the US economy displays a hump-shaped pattern in response to shocks, and the autocorrelation of aggregate investment growth is positive for the first few quarters, turning negative for the later quarters. This paper shows that this feature of the data is the natural outcome of a two-sector consumption/investment model designed and calibrated to reproduce plant-level evidence on capita: accumulation.

Clinical correlates of social adjustment in patients with obsessive-compulsive disorder

Background: Patients with obsessive-compulsive disorder (OCD) frequently show poor social adjustment, which has been associated with OCD severity. Little is known about the effects that age at symptom onset, specific OCD symptoms, and psychiatric comorbidities have on social adjustment. The objective of this study was to investigate the clinical correlates of social functioning in OCD patients. Methods: Cross-sectional study involving 815 adults with a primary DSM-IV diagnosis of OCD participating in the Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders. Patients were assessed with the Social Adjustment Scale, the Medical Outcomes Study 36-item Short-Form Health Survey, the Yale-Brown Obsessive-Compulsive Scale, the Dimensional Yale-Brown Obsessive-Compulsive Scale, and the Structured Clinical Interview for DSM-IV Axis I Disorders. Clinical correlates of social adjustment were assessed with generalized linear models with gamma distribution. Results: Poor overall social functioning was associated with greater OCD severity (p = 0.02); hoarding symptoms (p = 0.004); sexual/religious obsessions (p = 0.005); current major depressive disorder (p = 0.004); current post-traumatic stress disorder (p = 0.002); and current eating disorders (p = 0.02). Poor social adjustment was also associated with impaired quality of life. Conclusions: Patients with OCD have poor social functioning in domains related to personal relationships and professional performance. Hoarding symptoms and sexual/religious obsessions seem to have the strongest negative effects on social functioning. Early age at OCD symptom onset seems to be associated with professional and academic underachievement and impairment within the family unit, whereas current psychiatric comorbidity worsen overall social functioning. In comparison with quality of life, social adjustment measures seem to provide a more comprehensive overview of the OCD-related burden. (C) 2012 Elsevier Ltd. All rights reserved.
