Cattle Fecal Decomposition on \u3cem\u3ePennisetum purpureum\u3c/em\u3e Schum. Pastures Managed under Different Post-Grazing Stubble Heights

Pasture management may affect cattle diet. Post-grazing stubble height is a pasture structural characteristic intrinsically linked to forage quantity and quality. Stubble height also indicates forage utilization rate, and as a result, affects nutrient pathway return (excreta or litter) and ultimately, nutrient cycling. Cattle excreta deposition affects soil chemical and physical characteristics (Carran and Theobald 2000). Slow release of nutrients from cattle dung, however, delays nutrient bioavailability for subsequent forage growth (Haynes and Williams 1993). This study evaluated how different post-grazing stubble heights on elephant grass (Pennisetum purpureum Schum.) pastures may affect cattle dung decomposition and nutrient release

Pernambuco Semiarid Native Rhizobial Populations Nitrogen Fixation Potential with Native \u3cem\u3eMacroptilium\u3c/em\u3e

Nitrogen (N) is one of nature´s most abundant elements, accounting for about 78% of the atmospheric gases, but mostly as the inert N2 form. As such it is not directly available to plants, and is relatively scarce in most agroecosystems. Biological nitrogen fixation (BNF) through diazotrophic bacteria represents ca. 63% of the yearly N input in terrestrial ecosystems (Taiz and Zeiger 2004). Legumes which form effective symbiosis with the diazotrophic group of bacteria commonly known as rhizobia, are a very important source of available N. Tropical forage legumes are usually able to nodulate with a diverse population of rhizobia, and may have a relevant contribution to nitrogen availability in pastures (Santos et al. 2003). This diversity may be exploited to find more symbiotically efficient bacterial strains, thereby increasing legume effects on pastures. One way to evaluate this diversity is to isolate strains from different regions, vegetation covers or cultivation systems, and environmental conditions. This practice would potentially lead to a large number of isolates, which would increase the chance of finding some more efficient than those currently available (Chagas Junior et al, 2010). Native legumes, including several species of Macroptilium are an important forage resource in the Brazilian Northeast semiarid, contributing to the quality of ruminant diet, but they are still not well known in regards to their BNF ability. This work evaluated nodulation efficiency of Macroptilium lathyroides when inoculated with Litolic Neossol from eight municipalities of Pernambuco State semiarid

A longitudinalidade e a integralidade no cuidado às crianças menores de um ano: avaliação de cuidadores

Objective: This study aimed to evaluate the attributes longitudinality and comprehensive care in Family Health Units in Vitória da Conquista, Bahia, Brazil. Method: quantitative, cross-sectional study with data collected through the use of the Brazilian version of Primary Care Assessment Tool. This instrument covers the essential attributes of the Primary Health Care, including longitudinality and comprehensive care. We interviewed 271 caretakers of children under one year old who use the health facilities, from January to June 2012. Results: longitudinality scores were high (3.07±0.53), demonstrating good experience of caretakers regarding the actions derived from this attribute. On the other hand, the scores for comprehensive care related to available services and services provided were low (2.83±0.36 and 2.81±0.98). Such results demonstrate little awareness of caretakers related to available services, as well as services provided to children by health facilities. Conclusions: Family Health Strategy is a reference for most health needs of the child; it promotes the relationship between caretakers and health professionals, and enables the knowledge about children health status. However, despite the high coverage of the Family Health Strategy in the county, some children´s health actions are not experienced by caretakers. Managers and health professionals should have the priorities for child health in their agendas, as well as planning and implementation of actions which are related to the child health needs.Objetivo: avaliar os atributos longitudinalidade e integralidade da atenção em Unidades de Saúde da Família em Vitória da Conquista, Bahia, Brasil. Método: pesquisa quantitativa, transversal com dados coletados mediante uso do Instrumento de Avaliação da Atenção Primária, versão nacional Primary Care Assessment Tool. Este instrumento contempla os atributos essenciais da APS, dentre eles a longitudinalidade e a integralidade da atenção. Foram entrevistados 271 cuidadores de crianças menores de um ano, usuários dos serviços, no período de janeiro a junho de 2012. Resultados: a longitudinalidade apresentou escore elevado (3,07±0,53), demonstrando boa experiência dos cuidadores com as ações derivadas desse atributo. Por outro lado, os escores para integralidade, tanto para serviços disponíveis quanto para serviços prestados, foram baixos (2,83±0,36 e 2,81±0,98). Tais resultados apontam pouca percepção dos cuidadores sobre serviços disponíveis, como também serviços prestados à criança pelas unidades de saúde. Conclusões: A ESF constitui referência para a maioria das necessidades de saúde da criança, favorece a relação entre cuidadores e profissionais, além de possibilitar o conhecimento da situação de saúde desse público. Entretanto, apesar da alta cobertura da estratégia no município, algumas ações em saúde voltadas às crianças não são vivenciadas pelos cuidadores. Aos gestores e profissionais de saúde que atuam com esta clientela, cabe a sensibilização sobre as prioridades dentro de suas agendas, como também o planejamento e a implementação de ações que estejam dentro das necessidades de saúde da população infantil

Hydatidiform mole resulting from sexual violence

<p>Abstract</p> <p>Background</p> <p>Hydatidiform mole (HM) is characterized by abnormal proliferation of human trophoblast with producers functioning tissues of human chorionic gonadotropin. It can evolve with ovarian cysts tecaluteínicos, hypertension of pregnancy or hyperthyroidism. The incidence of HM is variable and its etiology poorly known, associated with nutritional factors, environmental, age, parity, history of HM, oral contraceptives, smoking, consanguinity or defects in germ cells. There is no reference in literature on HM resulting from sexual violence, objective of this report.</p> <p>Method</p> <p>Description of two cases of HM among 1146 patients with pregnancy resulting from sexual violence treated at Hospital Pérola Byington, São Paulo, from July 1994 to August 2011.</p> <p>Results</p> <p>The cases affected young, white, unmarried, low educated and low parity women. Sexual violence was perpetrated by known offenders unrelated to the victims, under death threat. Ultrasound and CT of the pelvis showed bulky uterus compatible with HM without myometrial invasion. One case was associated with theca lutein cysts. The two cases were diagnosed in the second trimester of pregnancy and evolved with hyperthyroidism. There was no hypertension, disease recurrence, metastasis or sexually transmitted infection.</p> <p>Conclusion</p> <p>The incidence of HM was 1:573 pregnancies resulting from rape, within the range estimated for Latin American countries. Trophoblastic material can be preserved to identify the violence perpetrator, considering only the paternal HM chromosomes. History of sexual violence should be investigated in cases of HM in the first half of adolescence and women in a vulnerable condition.</p
