Caracterização da população portadora de tuberculose do município de Américo Brasiliense/SP, no período de 1992 a 2002

Tuberculosis (TB) is a serious public health problem all over the world, which was recognized by the WHO in 1993 as a global emergency because of its very high incidence in the 22 countries that concentrate 80% of TB cases. One of these countries is Brazil, where TB occurrences are well-documented in major cities, but little is known of its spread in rural areas and small towns. Therefore, an epidemiological study was done on medical records of TB sufferers in the rural district and small town of Américo Brasiliense, São Paulo state, from 1992 to 2002, with the aim of improving TB prevention and treatment. The results showed that the incidence of TB peaked in the years of intense migration of rural workers, largely cane-cutters. Among these, the disease attacks mainly the men, in their productive years (20 to 40 years old). The predominant clinical form observed was pulmonary tuberculosis. The treatment abandonment rate was less than 1.8%, while the cure rate was around 90%. The disease detection rate by examination of sputum for acid-fast bacilli was around 60%.

Proveniência e idade do metamorfismo das rochas da faixa Brasilia, na região de tapira (SW de Minas Gerais)

The Brasilia Fold Thrust Belt at Tapira area (SW of Minas Gerais State, Brazil) has four different litho-tectonic domains imbricated by thrust faults with vergency to the São Francisco Craton. Sm/Nd isotopic studies were undertaken and the results show different model and metamorphic ages for the thrust sheets. Rocks from the lower thrust sheet yield a metamorphic age of 543 Ma while the upper thrust sheet has a metamorphic age of 581 Ma. The TDM model ages are similar for both thrust sheets, between 1.7 and 2.2 Ga. Because of their lithologic characteristics, the thrust sheets are interpreted as having been deposited in a distal continental platform environment, their main source being Paleoproterozoic rocks of the São Francisco Craton. The upper thrust sheet rocks presents a metamorphism age of 612 Ma and a bimodal distribution of TDM model ages between 1.3 and 1.9 - 2.0 Ga, respectively. The lithologic and isotopic characteristics of this thrust sheet the rocks are interpreted as a result of deposition on a continental slope or oceanic floor environment, with mixed contributions from Paleo - and Mesoproterozoic rocks of the São Francisco Craton. In spite of the small number of analyzed samples and the uncertainties inherent to the Sm/Nd method the metamorphisms are not considered to be synchronous in the different thrust sheets. This is to be expected in a thrust belt system, in which the more metamorphosed thrust sheets are juxtaposed to less metamorphosed ones.

Avaliação da transferência de imunidade passiva em cordeiros com até 30 dias de idade

The aim of this study was to determine the serum concentrations of immunoglobulin G, TP and the γ globulin electrophoretic fraction, as well as the enzymatic activities of GGT and ALP. This was done in order to explore the possibility of using changes in activities of these enzymes as indirect indicators of adequate humoral immunity and/ or failure of immune passive transfer in lambs. Pearson correlation was performed between variable of four groups of age during the first 30 days of life. Blood samples (191) from lambs from 21 different farms in Araçatuba region- São Paulo. The following tests were perfomed: radial immunodiffusion, spectrophotometry and electrophoresis to stain the amount of IgG, TP and γ globulin, respectively. GGT and ALP values were determinate using commercial kits. There was a statistically significant correlation between ALP and GGT. The same correlation was observed from TP, IgG and GGT. A positive γ globulin correlation was found between GGT, IgG and TP. ALP activity cannot be used as an indicator of immune passive transfer.

Treinamento esfncteriano anal: Estudo transversal em crianças de 3 a 6 anos de idade

Objective: To assess the practice of children's toilet training through interviews with parents and caretakers. Methods: A cross-sectional study of healthy children using a questionnaire applied to parents or caretakers of 100 consecutive children aged 3 to 6 years old. Results: 97% of the children were home-trained by their mothers and 92% of them used their intuition, previous experience with an older child and grandmothers' experience. Bowel and bladder toilet training started simultaneously in 84% of the cases, whereas 41% of the children mastered stool control earlier. Mothers with lower educational level and of social classes C, D and E initiated the training earlier and one of the related reasons was the cost of disposable diapers. Age in initiation or duration of toilet training was similar for boys and girls. Children presented most of the readiness symptoms for toilet training and only a small number of them used a seat reducer or a foot support. There was no increase in constipation prevalence after toilet training and there was no encopresis. Conclusions: Mothers were responsible for bowel toilet training and initiated it with no specialized help. In C-D-E social classes, the cost of diapers was determinant to initiate bowel toilet training.

Comparação entre metodologias para avaliar a idade à primeira concepção em éguas puro-sangue inglês

In Brazil, due to the breeding season for Thoroughbred, the reproductive data are normally truncate, since the breeders try to get animals that were born at the beginning of the breeding season in order to take their competitive advantages (more developed, mature and trained animals) compared to animals born later in the same breeding season. To analyze these data suitable methods should be used. Then, this paper aims to compare three methodologies: the method of maximum restricted likelihood, using MTDFREML, bayesian analysis without censured data by software MTGSAM and bayesian analysis with censured data by software LMCD, to evaluate age at first conception in thoroughbred mares, in order to verify its impact on the choice of stallions during selection. The database contained 3509 records for age at first conception (months) for thoroughbred mares. The heritability estimates were 0.23, 0.30 and 0.0926 (log scale), for MTDF, MTGSAM and LMCD, respectively. Considering all animals in the pedigree (6713), ranking correlations varied from 0.91 to 0.99. When only stallions were considered (656), those varied from 0.48 to 0.99 (considering different percentages of selected males) between evalua-tion methods. The highest changes in the general classification were observed when LMCD was compared to the other two methods. As the linear censured model is the most suitable for trait analysis with censured data, it was observed that censure information would lead to the choice of different animals during the selection process, when compared to the two other methodologies.

Desempenho e morfometria duodenal de frangos de corte submetidos a diferentes níveis de energia e programas de alimentação de 42 a 57 dias de idade

This experiment was conducted to evaluate the use of different energy levels and amino acid recommendations on performance, carcass yield and intestinal morphometry of broilers from 42 to 57 days of age. We used 1,600 one-day old male broilers (Cobb 500) in a completely randomized design arranged in a 2x4 factorial scheme with 3,200 and 3,600 kcal ME/kg and four different feed programs. The metabolizable energy levels and the feed programs did not determine significant differences in carcass characteristics for choosing a level of energy or a feed program, thus the energy level and the recommendations of amino acids that determine the highest cost-benefit ratio should prevail. It was observed that 3,600 kcal ME/kg resulted in some improvement on performance and morphometry of the intestinal mucosa, also the fractioning of digestible amino acid requirements during two periods resulted in worse performance and intestinal villi height.

Idade masculina: Qualidade do sêmen e fertilidade: Idade masculina X qualidade seminal

The man's age seems to affect reproductive function but to a lower degree compared with the woman's age. In fact, the effect of paternal age on semen quality has been discussed, but the results are contradictory. Considering the differences in the results of studies, this review aimed to analyze the literature regarding the effect of paternal age on semen parameters (volume, concentration, motility and morphology) in sperm DnA damage in assisted reproduction results and genetic diseases.

Nitrogênio e idade de corte na qualidade da biomassa de capimelefante para fins agroenergéticos cultivado em Latossolo

Nowadays one of the major challenge for research is the production of alternative agrifuels energy material derived from plant biomass. Allied to this, the proper management of nitrogen, becomes fundamental for productivity gains and improvement in quality of elephant grass biomass. Thus, the objective was to evaluate the effect of nitrogen fertilization and plant age effect on the quality of elephant grass biomass for energy purposes. The experiment was performed with genotype Paraíso, grown in a dystrophic Oxisol in the southern state of Tocantins. The design was randomized blocks with subdivided plots, situating plots as nitrogen rates (0, 50, 100 and 150 kg ha-1) and the subplots cutting age (120, 150 and 180 days after planting ) four replicates. We evaluated the relationship carbon/nitrogen (C:N) and leaf/stem (L:S), levels of neutral detergent fiber (NDF) and ash contents in dry biomass produced. The application of nitrogen increased by 12% to C:N ratio of the plant. The advanced age of cut forage was increased 9% in the C:N plant, however, decreased by 12 and 14% levels of ash produced in the stem and leaves, respectively. The production of elephant grass for agrifuels is feasible with management system proposed, quality characteristics desirable, such as high C:N ratio, above 40% and higt fiber content, above 50%.

Relação entre idade cronológica, indicadores de adiposidade corporal e aptidão física relacionada à saúde em meninos e meninas

Objectives. The purpose of this study was to analyze the relationship between adiposity indicators, age and physical fitness related to health. Methods. The sample involved 43 boys and 53 girls. The tests applied were: the Sit-up (S), Modified Pull-up (MP) and Run/Walk (RW) tests. Fat indicators were: Body Mass Index (BMI), subscapular (SB), triceps (TR), and calf (C) skinfolds; the skinfolds sum (Σ) and percentage of fat mass (%F). Results. The results indicated negative correlation between MP and TR, MC, Σ and %F for boys and girls (r = -0,42 a r = -0,52, P ≤ 0,01). There was positive correlation among the S test and age for both groups (r = 0,35, P ≤ 0,05 a r = 0,52, P ≤ 0,01), and negative on the S test with SB, MC and %F for the girls (r = -0,28 a r = -0,29, P ≤ 0,05). Negative correlation also was verified between RW with TR for the boys (r = -0,30, P < 0,05). Conclusion. Age seemed to be related with better performance, and adiposity with weaker performance, mostly in the MP where it is necessary to support their own body mass. Thus, these factors should be considered in the interpretation of results and when establishing criteria for health-related tests with these characteristics. © 2013 Revista Andaluza de Medicina del Deporte.

Exigência de treonina digestível para codornas de corte no período de 15 a 35 dias de idade

The digestible threonine (DThr) requirements for meat quails (Coturnix coturnix sp) during growing phase from 15 to 35 days of age were estimated, using 1,020 quails with 15 days of age, of both sexes, distributed in a completely randomized design, with six levels of digestible threonine-0.93; 1.00; 1.07; 1.14; 1.21 and 1.28% in diet, five replications and 34 quails per experimental unit. There was no effect on performance variables, carcass yield and chemical composition and nitrogen balance with the studied increase in digestible threonine levels. There was a linear increase in threonine intake and feed cost per kilogram of body weight gain with increasing levels of digestible threonine. It was concluded that the best level of threonine evaluated was sufficient to meet the requirements of meat quails, in the period from 15 to 35.

Nível de atividade física, comorbidades e idade de pacientes hipertensos

Physical inactivity is associated with chronic diseases in older adults. There are different domains of physical activity, such as leisure and locomotion. This study investigate the associations between different domains of physical activity, comorbidities and aging in hypertensive adults. Participants included 192 hypertensive respondents classified in groups of active and insufficiently active for leisure-time, locomotion, occupation and total time. They were stratified in age groups. Waist circumference was measured and comorbidities were self-reported. The chi-square test analyzed these associations; a one-way ANOVA compared the age groups (significance at p <0.05). The mean total time and occupational physical activity were lower for groups ages over 60 and 70 years, respectively. Occupational activity was associated with age in the female group, and with cholesterol and diabetes in males, who also had physical activity of locomotion associated with waist circumference. Physical activity of hypertensive patients is associated with comorbidities in different age groups and sex.
