Low-grade chronic systemic inflammation is often associated with chronic non-communicable diseases, and its most frequently used marker, the C-reactive protein (CRP), has become an identifier of such diseases as well as an independent predictor for cardiovascular disorders and mortality. CRP is produced in response to pro-inflammatory signaling and to individual and behavioral factors, leading to pathological states. The aim of this study was to rank the predicting factors of high CRP concentrations in free-living adults from a community-based sample. We evaluated 522 adults (40-84 years old; 381 women) for anthropometric characteristics, dietary intake, clinical and physical tests, and blood analysis. Subjects were assigned to groups, according to CRP concentrations, as normal CRP (G1;<3.0 mg/L; n = 269), high CRP (G2; 3.0-6.0 mg/L; n = 139), and very high CRP (G3; >6.0 mg/dL; n = 116). Statistical comparison between groups used one-way ANOVA or Kruskal-Wallis tests, and prediction of altered values in increasing CRP was evaluated by proportional hazard models (odds ratio). CRP distribution was influenced by gender, body mass index, body and abdominal fatness, blood leukocytes, and neutrophil counts. The higher CRP group was discriminated by the above variables in addition to lower VO2max, serum metabolic syndrome components (triglycerides, glucose, and HDL cholesterol), higher insulin, homeostasis assessment of insulin resistance, uric acid, gamma-GT, and homocysteine. After adjustments, only fatness, blood leukocytes, and hyperglycemia remained as independent predictors for increased serum CRP concentrations. Intervention procedures to treat low-grade chronic inflammation in overweight women would mainly focus on restoring muscle mass and functions in addition to an antioxidant-rich diet. © 2012 Springer Science+Business Media, LLC.

O cavalo, dado o seu meio ambiente, está sujeito a afecções frequentes da córnea e da conjuntiva, tecidos oculares bastante expostos a bactérias e fungos, principalmente Aspergillus spp. e Fusarium spp. As ceratites ulcerativas bacterianas e fúngicas, bem como as ceratites fúngicas não ulcerativas, caracterizadas principalmente pelo abscesso estromal, são frequentes nessa espécie. Ocorrida a lesão inicial, perpetua-se um ciclo vicioso, com liberação de citocinas inflamatórias, que desencadeiam uma rápida e severa infiltração corneal por células polimorfonucleares. A córnea torna-se sujeita à destruição por enzimas proteolíticas liberadas pelos micro-organismos e por células inflamatórias, capazes de desencadear a dissolução estromal e a perfuração do bulbo ocular. O tratamento clínico para a resolução da doença corneal e o controle da uveíte reflexa deve ser agressivo e associado, muitas das vezes, à terapia cirúrgica. Este artigo discorre sobre a fisiopatologia e o tratamento da ceratomicose em equinos.

The present research was accomplished under field and laboratory conditions (T= 25[plus or minus]2[degree] C, R.H.= 70[plus or minus] 10 % and fotoperiod= 12 horas) at FCA/UNICASTELO from Fernandopolis-SP, Brazil. The feeding preference of corn bug Leptoglossus zonatus Dallas, 1852 (Hemiptera: Coreidae) was evaluated on corn genotypes AL-Bianco, AL-Manduri, AL-25 Piratininga, AL-34 e AL-Manduri in the field. Besides, some behavioral factors relative to infestation and oviposition were observed. In laboratory, the nymph's development was evaluated on ears from each corn genotype, aiming to verify the non-preference and/or antibiosis ocurrence. The females of L. zonatus preferred to oviposite on sheats from leaves. Adults and nymphs may occur in whole parts of the plants. The AL-25, AL-34, AL-Manduri and AL-Bandeirante corn genotypes were classified as moderately resistant, expressing non-preference and/or antibiosis against the corn bug. In other way AL-Bianco was the most suscetible to nymphs of the insect.

Este estudo teve como objetivo descrever a população de profissionais do sexo, considerando características sociodemográficas, antecedentes gineco-obstétricos e comportamentais, e verificar a associação com a presença de doença sexualmente transmissível. Trata-se de estudo epidemiológico e transversal, realizado com 102 mulheres profissionais do sexo. Os dados foram obtidos por meio de entrevista e exames padrão-ouro para diagnóstico das doenças de interesse. A média de idade das mulheres foi de 26,1 anos, sendo que a maioria tinha nove ou mais anos de aprovação escolar, era solteira e teve coitarca antes dos 15 anos. A prática de sexo oral nos parceiros foi citada por 90,2% das mulheres, 99% delas relataram fazer uso de preservativo no trabalho, apenas 26,3% com parceiros fixos e 42,2% usavam drogas ilícitas. Não houve associação entre fatores sociodemográficos, antecedentes gineco-obstétricos e fatores comportamentais com presença de doença sexualmente transmissível e isso pode ser decorrente da escolaridade e do fato da população estudada possuir características muito semelhantes, dificultando o aparecimento de tais associações.

Statement of problem. The oral mucosa has been reported to show a variety of changes in subjects with diabetes mellitus.Purpose. The purpose of this study was to compare diabetic and nondiabetic subjects wearing complete dentures with regard to salivary flow, salivary buffering capacity, denture retention, and oral mucosal lesions.Material and methods. Sixty subjects, 30 with and 30 without a diagnosis of diabetes, were matched for gender, race, and age. Salivary flow, salivary buffering capacity, glycemia, blood pressure, presence of mucosal lesions, denture retention, use of medications, and behavioral factors (controlled or uncontrolled diet, alcohol consumption, and smoking) reported by the subjects, were evaluated. For the salivary buffering capacity test, 1 mL of saliva was pipetted into a test tube containing 3 mL 0.005 N of hydrochloric acid, and the pH was measured with indicator strips. Group differences were statistically analyzed using the Student t test and the Mann-Whitney test for quantitative variables and the chi-square test for qualitative variables (alpha = .05).Results. Mean (SD) salivary flow was 1.14 (0.87) mL/min in the nondiabetic subjects and 0.95 (0.61) mL/min in the diabetic subjects. Evaluation of self-reported denture retention revealed no significant difference between groups. Denture retention was observed in 66.7% (20/30) of the control group and in 50% (15/30) of the diabetic group. The prevalence of mucosal lesions was 90% (27/30) in the control group and 83.3% (25/30) in the diabetic group. Salivary buffering capacity was 5.80 (0.85) in the control group and 5.26 (0.83) in the diabetic group (P = .017).Conclusions. Within the limitations of this study, no significant differences were observed in salivary flow, denture retention, or oral lesions in diabetic and nondiabetic subjects.

Brazil is the world leader in broiler production and export. It achieved this position mainly to its excellent supply chain structure and climate, which favor poultry and grain production throughout its territory. Although Brazilian egg production is not as important as broiler production, this segment presents great potential of increasing its share in the global market. However, as elsewhere in the world, Brazilian poultry production faces the challenge to balance two elements within its supply chain: cruelty and productivity. The consumers of the European Union (EU) are very concerned with animal welfare issues. In order to increase its share in the European market, and eventually in the world market, Brazilian poultry producers must understand the effects of production systems on poultry welfare, and try to develop systems that are suited for its climate and other production conditions. There is a consensus that the natural behaviors performed by poultry in intensive production systems allow better welfare. This objective of this review is to present scientific research studies that relate different behaviors to chicken welfare. Poultry behavior is a reflex of their welfare status at a particular moment, and it is related to internal (physiological) and external (environmental) factors. Several natural behaviors that favor welfare, as well as undesirable behaviors, may be stimulated by environmental enrichment. The correct interpretation of the behaviors expressed by poultry, including their frequency, duration, and sequence, may be used to estimate their welfare. Animal production is an import sector of Brazilian economy. It significantly contributes to the Gross Domestic Product (GDP), in terms of products destined both to domestic consumption and exports. New technologies applied to products and management practices have been developed for field application, aiming at improving producers' productivity and profitability. In order to comply with the European Union's (EU) guidelines for animal protein production, Brazilian poultry production needs to undergo a process of adaptation. In May, 2007, the EU Commission established its new guidelines for animal welfare in poultry production, pressured by consumer demand. In the EU, there is a growing concern among consumers as to how poultry are reared and slaughtered. European consumers are in the fore front of the demand of high quality products produced with under better welfare conditions, and have spread this concern throughout the world. Beaumont et al. (2010) mentioned that European consumers frequently perceive that standard commercial poultry production has poor animal welfare practices. According to Nääs et al. (2008), Brazilian poultry production today needs to find a balance between cruelty and productivity. In fact, ensuring animal welfare may provide better financial results, as it increases the producer's profit margins and allows maintaining Brazilian chicken export quotas to the EU. França (2008) noted that biological studies that define ethical limits and guidelines for poultry production foster the development of new production practices that may ensure good product quality and productivity without putting bird welfare at risk. Gonyou (1994) states that, when animal welfare started to be studied, the only behavioral factors considered were those related to feeding and reproduction. These first studies used as indicators of animal welfare reduced life expectancy, impaired growth, impaired reproduction, body damage, disease, immunosuppression, adrenal activity, behavior anomalies, and self-narcotization (Broom, 1991). However, current studies evaluate additional indicators, such as natural behaviors, behavioral needs, preferences, behavioral problems, emotional state, cognitive abilities, etc. In the field of ethology, the expression of natural behavior is a frequently used tool used to estimate the welfare of poultry destined to human consumption. According to Bracke & Hopster (2006), natural behavior can be defined as the behavior the animal normaly presents when exposed to conditions similar to its natural habitat. Natural behaviors are pleasurable and promote biological functions that are meaningful to the animal's welfare. The definition of natural behavior, though, does not include the bird's behavior when sick, in flight or during aggression, since these are not considered pleasurable situations. Considering layer behavioral needs in the design of housing facilities optimize their welfare. Mishra et al. (2005) verified that ISA Brown layers spent, during 24 hours, around 97% of the time in the nest, feeding, walking, resting, or dust bathing, and that 57% of these behaviors did not depend on environmental enrichment. It was also observed that hens had preferred behavioral sequences, which included foraging and comfort behaviors, such as wing-stretching and preening. The present review aims at discussing, albeit not exhaustively, scientific research studies on the behavior of Gallusgallus domesticus and its relationship to welfare. The following behaviors are reviewed: feather pecking, scratching, dust bathing, nesting, locomotion activities, and aggressive behaviors. These behaviors are the most frequently observed in commercial broiler, broiler breeder, and layer farming, and therefore, monitoring their incidence may contribute to measure poultry welfare.

OBJETIVO Analisar o padrão de atividade física de gestantes de baixo risco e os fatores associados. MÉTODOS Estudo transversal com 256 gestantes adultas no segundo trimestre gestacional, sorteadas dentre as assistidas pelas unidades de atenção primária à saúde do município de Botucatu, SP, em 2010. As atividades físicas foram investigadas por meio do “pregnancy physical activity questionnaire”, verificando-se tempo e intensidade de atividades ocupacionais, de deslocamento, domésticas e de lazer, expressos em equivalentes metabólicos dia. As gestantes foram classificadas segundo nível de atividade e em relação a atingir 150 min/semana de atividades físicas de lazer, variáveis dependentes do estudo. A associação entre essas variáveis e as socioeconômicas, características maternas, fatores comportamentais e modelo de atenção da unidade de saúde foi avaliada mediante modelos de regressão de Poisson com variância robusta, adotando-se modelo hierárquico. RESULTADOS A maior parte das gestantes era insuficientemente ativa (77,7%), 12,5% moderadamente ativa e 9,8% vigorosamente ativa. Os maiores gastos diários de energia foram com atividades domésticas, seguidas pelas atividades de locomoção; 10,2% atingiram a recomendação de 150 min semanais de atividades físicas de lazer. Trabalho fora de casa reduziu a chance de atingir essa recomendação (RP = 0,39, IC95% 0,16;0,93). Ter tido pelo menos um parto anterior (RP = 0,87, IC95% 0,77;0,99) e excesso ponderal pré-gestacional (RP = 0,85, IC95% 0,731;0,99) reduziram a chance de ser insuficientemente ativa, enquanto consumir menos alimentos saudáveis teve aumento discreto (RP = 1,18, IC95% 1,02;1,36). CONCLUSÕES Gestantes assistidas na atenção primária à saúde são insuficientemente ativas. Ter tido pelo menos um parto e apresentar sobrepeso pré-gestacional foram identificados como fatores protetores contra tal situação, enquanto consumo menos frequente de alimentos saudáveis foi fator de risco, sugerindo aglomeração de fatores de risco à saúde.
