Situação do aleitamento materno em população assistida pelo programa de saúde da família-PSF

Este estudo objetivou identificar a prevalência dos diferentes tipos de aleitamento e sua relação com variáveis maternas no município de Conchas-SP, totalmente coberto pelo PSF. Foram obtidas informações sobre a alimentação atual das crianças menores de um ano que compareceram à primeira etapa da Campanha de Multivacinação de 2003. As associações foram submetidas ao teste do qui-quadrado, adotando-se 5% como nível de significância estatística. As prevalências do Aleitamento Materno Exclusivo (AME) e do Aleitamento Materno Predominante (AMP), em menores de 4 meses de vida, foram 25,4 e 44,4%, respectivamente, e 66,7% do total de crianças menores de um ano ainda eram amamentadas. A prevalência do AME em menores de 6 meses foi heterogênea, variando de 7,4 a 41,2%, conforme a equipe do PSF de procedência das crianças. Ter passado por dificuldades no início do aleitamento associou-se a menores prevalências de AME e Aleitamento Materno (AM). Esses resultados evidenciam situação distante da recomendada pela Organização Mundial de Saúde e aquela para a qual há evidências de máximo efeito protetor à saúde infantil, reafirmam a necessidade de apoio às mães no período puerperal precoce e demonstram a importância de diagnósticos desagregados por regiões para o planejamento de ações de promoção ao AM.

Efeitos de rações com níveis crescentes de cana-de-açúcar em substituição à silagem de milho sobre a população de protozoários ciliados no rúmen de ovinos

Oito ovinos machos com fístulas ruminais foram delineados em dois quadrados latinos, em quatro períodos de 35 dias cada e quatro tratamentos, compreendendo níveis crescentes de cana-de-açúcar (CA) em substituição à silagem de milho (SM): A) 100% SM; B) 67% SM e 33% CA; C) 33% SM e 67% CA; e D 100% CA, para avaliação da população de protozoários ciliados no rúmen. As concentrações totais de protozoários ciliados no rúmen e de Entodinium diminuíram e os valores de pH do conteúdo ruminal aumentaram linearmente com o incremento das quantidades de cana-de-açúcar na ração. Não houve diferenças entre tratamentos para o volume ruminal e a taxa de passagem da fase líquida do rúmen.

População protozoários ciliados e degradabilidade ruminal em búfalos e bovinos zebuínos sob dieta à base de cana-de-açúcar

Três búfalos e três bovinos zebuínos adultos com cânulas ruminais foram alimentados à vontade com dieta de cana-de-açúcar fresca e picada, suplementada com 3 kg de concentrado/animal, durante 13 semanas. Após duas semanas de adaptação, amostras do conteúdo ruminal foram coletadas semanalmente, em dois tempos de amostragem: antes da alimentação e 40 minutos após para determinação da concentração e composição da fauna ruminal. Na quinta semana do experimento, os conteúdos ruminais foram misturados e reinoculados entre animais de mesma espécie e, na última semana, estimadas as degradabilidades in situ da MS, PB e FDN da cana-de-açúcar e MS e PB do concentrado. A concentração média de protozoários foi maior em bovinos, de 4,85 x 10(5)/mL, que em búfalos, de 3,82 x 10(5)/mL. As composições genéricas para Entodinium e subfamília Diplodiniinae foram 79,2 e 6,2% em bovinos e 32,0 e 54,9% em búfalos, respectivamente. Não houve interação significativa entre espécies animais e tempo de amostragem. Houve aumento da concentração média dos holotricos após 40 minutos da alimentação. As degradabilidades efetivas dos nutrientes estudados foram semelhantes entre as duas espécies animais, observando-se diferenças na cinética da degradação. Concluiu-se que os búfalos apresentaram menor concentração de ciliados no rúmen, maior composição de Diplodiniinae e menor de Entodinium que os bovinos; os holotricos exibiram capacidade de migração e seqüestro no rúmen em ambas as espécies; e as diferenças na fauna ruminal não influenciaram a degradabilidade efetiva dos nutrientes da cana-de-açúcar e do concentrado.

Distribuação do sistema radicular de aveia preta em função da população e espaçamento

The experiment was carried out at Sao Manuel Experimental Farm, Agronomy College, São Paulo State University, Brazil, in a Dark-Red Latosol (loamy sand) to verify oat (Avena strigosa Schreber) rooting patterns under different plant populations (1,5 x 10(6) and 2.5 x 106 plants/ha) and row spacings (0.20 and 0.30 m.). Soil and roots were sampled 81 days after planting, at bloom stage. Cylindrical cores with 2.6 cm diameter were taken from soil depths of 0-10, 10-20, 20-40 and 40-60 cm. At the same time, plant canopies where also sampled to determine the dry weight. Soil analysis showed P to be concentrated in the upper 10 cm whereas the bases were uniform in the profile. There was a high root concentration in the 0-10 cm layer (9.9 to 13.0 cm/cm3 under the row and 10.0 to 11.5 cm/cm2 in the inter-row), which was not related to chemical characteristics of the soil. There was no effect of plant population or row spacing on oat root distribution or growth in the soil profile.

Condições associadas ao grau de satisfação com a vida entre a população de idosos

OBJECTIVE: As a result of overall growing population's life expectancy, it has become increasingly important to ensure not only that the elderly have greater longevity but also happiness and life satisfaction. The objective of the study was to describe factors associated with life satisfaction among elderly people.METHODS: Three hundred and sixty-five older persons, selected by means of random stratified proportional sampling, were interviewed in 2003. The instrument used was a combination of Flanagan and Nahas questionnaires and WHOQOL-100. There were added questions concerning physical activity extracted from International Physical Activity Questionnaire, questions regarding reported morbidity and emotional assessment, sociodemographic condition and an open question. The level of life satisfaction was measured using a scale from one to seven by means of visual recognition. Hierarchical logistic regression analysis was performed including life satisfaction as a dependent variable and those included the final questionnaire, in blocks, as independent variables.RESULTS: Most elderly were generally rather satisfied with life as well as with specific aspects. The level of life satisfaction was associated with: comfort at home (OR=11.82; 95% Cl: 3.27; 42.63); appraising leisure as quality of life (OR=3.82; 95% Cl: 2.28; 6.39); waking up feeling well in the morning (OR=2.80; 95% Cl: 1.47; 5.36); not reporting loneliness (OR=2.68; 95% Cl: 1.54; 4.65); having three or more daily meals (OR=2.63; 95% Cl: 1.75; 5.90) and not reporting Diabetes Mellitus (OR-2.63; 95% Cl: 1.3 1; 5.27).CONCLUSIONS: Most elderly in the study were satisfied with life and their satisfaction was associated with situations related to being well and not being diabetic.

Prevalência de Demodex folliculorum e Demodex brevis em uma amostra da população de Botucatu, São Paulo, Brasil.

A survey was conducted to determine the prevalence of D. folliculorum and D. brevis for the first time in Brazil. In this study, association between the presence of mites and host factors (age, sex and race) were analysed. Samples were obtained from 100 individuals submitted to a facial cleaning in an aesthetic clinic in Botucatu city. All the samples were mounted in Berlese's medium and examined by dark-field phase microscopy. From 100 studied individuals, 72 were positive, among the positive cases, 51% showed D. folliculorum, 2% showed D. brevis and 19% both species. The parasite distribution in relation to sex was not taken in account because the sex ratio favoured females (90%). According to age, prevalence was high in all age groups. The factors influencing this distribution could be due. 1. the examination of extensive skin areas, 2. the group examined composed of individuals in treatment in an anaesthetic clinic could be more infested than a normal population, 3. the fact that in tropics, the prevalence is often high in all ages.

Avaliação da população canina da zona urbana do Município de Araçatuba, São Paulo, SP, Brasil

Planning control programs, for diseases such as rabies requires information on the size and structure of the dog and cat population. In order to evaluate the dog population of the urban area of Araçatuba city, S. Paulo State, Brazil, a survey was conducted using a questionnaire to interview members of households. Eighty-eight districts were visited (37,778 houses) and the interview was possible at 77.93% of these. Human population size evaluated was 113,157 inhabitants. Houses that owned animals represented 55.2%, 26,926 of the animals concerned were dogs and 5,755 were cats. Of the dogs, 56.64% were 1-4 year olds and males represented 56.2% of the total population. Dog: person ratio was estimated at 2.8 dogs to every 10 persons, almost 3 times the ratio hitherto estimated and used in the planning of rabies vaccination campaigns.

Determinação de parâmetros genéticos em população de gonçalo-alves (Astronium fraxinifolium) através das características fisiológicas da semente

Seeds of Astronium fraxinifolium (Anarcadiaceae) were collected in two years, and submitted to tests of seed germination and vigour (first count, aging and electric conductivity), in order to verify the potencial of conservation and if variations in the seed quality presented on association with genetic parameters. Coefficient of heritability in average (ĥm 2) were 0.91 and 0.97 to germination; 0.90 and 0.96 to first count; 0.93 and 0.97 to aging and 0.95 and 0.99 to electric conductivity, for seeds collected in 1997 and 1998, respectively, evidencing a great heritability to all studied characteristics. Genetic variability was influenced more by environmental conditions of blooming and harvest of seeds than storage time.

Perfil demográfico e de morbidade da população idosa atendida nas dependências do pronto-socorro, ambulatórios e enfermarias no HC-Unesp em 1997

Being our objective to characterize demographic and morbidity patterns of the 60 years old or more attended at the UNESP Clinic Hospital in 1997 a sample consisting of 482 handbooks has been analyzed in order to evaluate ambulatory attendance, other consisting of 101 handbooks to evaluate first aid clinic demand and statistics from Medical Informatic Center (Centro de Informática da Medicina - CIMED) refering to 2652 internments of such populations this year. Ten and a half per cent from the total of first aid clinic attended patients refers to this old people and the majority (57,4%) lives in Botucatu County. More frequently diagnoses during consultation are Chronic Obstructive Lung Disease (10.1%), Congestive Cardiac Disease (4.7%), Asthma and Cataract (3.1 % for both). Such population is also referred to be 19.8% from the number of all patients attended at the UNESP ambulatories, 65.8% coming from other city in São Paulo State, being in average 69.6 years old and attending 4.5 consultations in average by year. More frequently found diagnoses referred to Essential Primary Hypertension (4.2%), Prostatic Nodular Hyperplasia (4.0%) and Nonspecified Cataract (3.3%). Regarding to internments, they referred to be 18.4% from the number of all interned patients. More frequent diagnoses at internmemt referred to Nonspecified Cataract (12%), Glaucoma (3.0%), Prostatic Nodular Hyperplasia (2.4%) and Limbs Arteriosclerosis (2.3%). Results indicates the existence of an tertiary hospital divided into specialties, also attending morbidity that should be in control into levels of primary and secondary attention.

Avaliação da população de neurônios mioentéricos NADPH-diaforase positivos do corpo do estômago de ratos com diabetes crônico induzido pela estreptozootocina

The aim of this study was to analyze the morphoquantitative features of the nitrergic myenteric neurons from the body of the stomach of diabetic rats. The body of the stomach of five normoglicemic rats and of five diabetic rats were prepared as whole-mounts stained by the histochemical technique of NADPH-diaphorase. Decreased body weight and increased daily ingestion of water, fast glicemia and glycated hemoglobin were verified in diabetic animals. According to the data obtained, significant difference in the density of nitrergic neurons was not observed between the two groups, but the areas of the neuronal cell body profiles in the diabetic rats were significantly larger. Results showed that the streptozotocin that induced diabetes does not accelerate the death of the nitrergic neurons, but increases the expression of these cells.

Série plaquetaŕria: Valores de referência e correlações observadas entre os parâmetros plaquetários em uma população aparentemente saudável

Mean platelet volume (MPV), platelet distribution width (PDW) and plateletcrit (PCT) platelet parameters can be important to improve the initial identification of platelet disorders. The purpose of this study is to establish reference values for the platelet count (PLT), MPV, PDW and PCT in a population of 1346 apparently healthy adults, from both sexes, as well as to evaluate the correlations among these platelet parameters and to build the necessary nomograms for the clinical interpretations of the platelet indices. The platelet parameters were analyzed in blood samples collected into dipotassium ethylenediaminetetra-acetic acid (K 2 EDTA) by an electrical aperture-impedance method. There were non-linear and an inverse correlations between MPV and PLT, and between PDW and PLT, throughout the reference range of platelet count: the change in MPV and PDW was most accentuated at the lower platelet counts. Because of this non-linear inverse correlation, MPV versus PLT and PDW versus PLT nomograms were built. These correlations among the platelet parameters on a normal population provide a better understanding of these indices and may contribute to establish the real clinical significance of these platelet parameters in many diseases.
