FOTOSSÍNTESE E TOLERÂNCIA PROTOPLASMÁTICA FOLIAR EM myracrodruon urundeuva FR. ALL. SUBMETIDA AO DÉFICIT HÍDRICO

The Myracrodruon urundeuva Fr. All. specie is known like aroeira-do-sertão, it belongs to Anacardiaceae family and it can be found in the Caatinga, Cerrado and Pluvial Forest. In the present study was tested on aroeira-do-sertão the water deficit effect under greenhouse conditions in two experimental blocks: the daily irrigation and the other with water deficit. It had tested with four repetitions by treatment and in three point of stem: basal, intermediary and apical. It was registered the data about photosynthesis rate, transpiration rate, stomatal conductance, relative water content and leaf protoplasmatic tolerance. The water deficit produced increment in relative water content in the leaves at the all positions leaves through the stem and reduced the transpiration and photosynthesis rates in the plants. The apical leaves were the most sensitive to the variations of the ambient. When the aroeira-do-sertão leaves were exposured to high temperature, they presented protoplasmatic tolerance mostly in the leaves located at intermediary position in the stem whose growth is complete

Conceito popular versus conceito médico de saúde e de doença

Reflexões acerca dos conceitos de saúde e de doença, dos pontos de vista popular e médico, levaram os autores a uma questão inquietante: quadro dialogam, médicos e pacientes falam a respeito da mesma coisa? Por meio de questionários e desenhos, obteve-se o conceito popular de saúde e de doença de 750 sujeitos: 630 pré-adolescentes estudantes e 120 adultos economicamente ativos. Os conceitos popular e médico de saúde e de doença foram comparados. Detectou-se uma coincidência entre os conceitos popular e médico acerca do que se entende como saúde. Com relação aos conceitos de doença, entretanto, verificou-se um descompasso. Para o médico, a doença é uma condição especial: nem sempre o homem-que-sofre apresenta uma doença ou estado mórbido. Para os leigos, entre os estado de saúde e de doença que, segundo eles, contrapõem-se quase que inteiramente, não existe um hiato. A partir desses achados, propõe-se uma mudança operacional nas relações conceituais entre saúde e doença, de modo a ampliar o campo de ação do médico, do ponto de vista clínico, na relação médico-paciente

Clinical and nutritional status of surgical patients with and without malignant diseases: cross-sectional study

CONTEXT: Malnutrition is frequently observed in inpatients with malignant diseases and may contribute to longer hospital stays. OBJECTIVE: To compare the nutritional status, lymphocyte count, hemoglobin values and length of hospital stay of patients with and without malignant diseases. METHODS: This comparative study assessed indicators of nutritional status, namely body mass index, recent weight loss, lymphocyte count, hemoglobin and length of hospital stay, of 928 surgical patients with and without malignant diseases (50.2% females and 49.8% males). The chi-square test was used to compare proportions and the Mann-Whitney test was used to compare continuous measurements between two groups. The significance level was set at 5%. RESULTS: Patients with malignant diseases had longer hospital stays (P<0.0001), furthermore, a higher percentage of patients with malignant diseases had body mass index <18.5 (P<0.0001) and experienced recent weight changes (P<0.0002). Lymphocyte count also differed statistically between the groups (P = 0.0131), which lower levels were identified among patients with malignant diseases. CONCLUSION: The lymphocyte count, hemoglobin values and weight loss are important findings of nutritional depletion in patients with malignant diseases

Tubal ligation regret and related risk factors: findings from a case-control study in Pernambuco State, Brazil Fatores de risco para o arrependimento da laqueadura tubária: resultados de um estudo de caso-controle em Pernambuco, Brasil

A case-control study was carried out at a public teaching hospital in Recife, Pernambuco State, Brazil in 1997 to investigate risk factors among women who feel regret after undergoing sterilization through tubal ligation. The study compared sterilized women who had requested or undergone a tubal reversal with women who were also sterilized but had not undergone this surgery, nor had requested to do so. Women showing a significantly greater probability of regret were those sterilized at a young age, those who had not themselves made the decision to undergo surgery , those for whom the sterilization was carried out up to the 45th day after childbirth and those who had acquired knowledge about contraceptive methods after the tubal ligation procedure. Having had a deceased child, a partner with no children prior to the current union or a change of partner after the tubal sterilization procedure were also associated to the request for or submission to tubal sterilization reversal. It is necessary to assess women's psycho-socio-demographic profiles, their reasons for requesting tubal ligation and to advise the patient about family planning in order to reduce rates of post-sterilization regret.<br>Um estudo do tipo caso controle foi conduzido em um hospital público de ensino no Recife, Pernambuco, Brasil, em 1997, para investigar os fatores de risco para o arrependimento da realização da laqueadura tubária, comparando mulheres laqueadas que solicitaram ou realizaram a reversão da laqueadura tubária com mulheres também laqueadas que não solicitaram e não se submeteram a esta cirurgia. As mulheres que mostraram uma maior probabilidade de arrependimento foram as esterilizadas quando jovens, as que não foram responsáveis pela decisão da cirurgia, as que realizaram a esterilização até o 45º dia pós-parto e as que adquiriram informações sobre métodos contraceptivos depois da laqueadura tubária. Morte de filhos, parceiros sem filhos anteriores à união atual e a mudança de parceiro após a laqueadura tubária também estiveram associados com a solicitação ou realização de reversão da laqueadura. Deve-se avaliar o perfil psicológico e sócio-demográfico das mulheres e seus motivos para solicitar a laqueadura tubária e aconselhá-las para o planejamento familiar a fim de reduzir os riscos de arrependimento futuro
