Sintomatologia depressiva e concentrações do cortisol em idosos residentes na comunidade: um estudo transversal

Introdução: Vem sendo crescente o número de pesquisas que buscam o entendimento das relações entre os desfechos adversos à saúde e as concentrações do cortisol salivar, o qual é um marcador de estresse biológico. O cortisol parece seguir dois estágios de resposta: em situações de baixo/moderado estresse ocorre ativação do eixo Hipotálamo-Pituitária-Adrenal, aumentando o nível do cortisol, entretanto, quando o estresse persiste, o eixo HPA parece tornar-se hipoativo. A sintomatologia depressiva parece ter relação com as concentrações do cortisol, no entanto, essa relação é controversa na literatura. Objetivo: Analisar a relação entre sintomatologia depressiva e concentrações do cortisol em uma amostra de idosos do Nordeste brasileiro, residentes na comunidade. Métodos: Estudo observacional analítico, de caráter transversal, em uma amostra de 256 idosos (≥ 65 anos), residentes na comunidade. A sintomatologia depressiva foi avaliada pela versão brasileira da Center for Epidemiologic Studies-Depression Scale (≥ 16) e as concentrações do cortisol através da coleta salivar (ao acordar, 30 minutos após acordar, 60 minutos após acordar, às 15 horas e antes de dormir), além de medidas compostas. Como co-variáveis foram avaliadas condições sociodemográficas e de saúde. Para análise das medidas do cortisol entre idosos com e sem presença da sintomatologia depressiva, e entre os sexos, foi realizado o teste t de Student. Para verificar as diferenças entre as medidas do cortisol em cada curva foi utilizada a Análise de Variância (ANOVA) de medidas repetidas, com teste post-hoc de Bonferroni. Resultados: Houve diferença significativa para a medida de cortisol salivar ao acordar, entre os idosos com presença e ausência da sintomatologia depressiva (p=0,04). Não houve significância em relação ao sexo. Na análise entre as medidas de cada curva, foi observado que nos idosos com sintomatologia depressiva a 1ª medida não teve diferença significativa em relação à 2ª e 3ª medidas. Além disso, não houve diferença significativa da 4ª medida em relação à 5ª, demonstrando um maior nível noturno de cortisol para os idosos com sintomatologia depressiva, sem declínio, com aspecto plano da curva. Conclusão: Parece existir relação entre sintomatologia depressiva e hipocortisolismo. Entretanto, no Brasil, as condições adversas de vida podem levar ao estresse crônico e serem fatores fortes suficientes para sobrepor maiores diferenças que pudessem existir em relação à presença da sintomatologia depressiva

Estágio menopausal e níveis hormonais no desenvolvimento muscular e funcional em mulheres de meia idade: um estudo transversal

Introduction: Hypoestrogenism is the main characteristic of female aging. It promotes significant changes in body composition, both in fat mass as in lean body mass, leading to a decrease in muscle strength and physical performance. Objective: The aim of this study was to test whether menopausal status and hormone levels are associated with muscular strength and physical performance in middle-aged women. Methods: In a cross-sectional study it was collected sociodemographic data, gynecological history, anthropometric and biochemical measures in women aged 40 to 65 years in Parnamirim-RN. The menopause status (pre, peri and post menopause) was determined by menstrual history. All women underwent three dimensions of physical performance assessment: handgrip dynamometry, gait speed and chair stands test - Short Physical Performance Battery (SPPB). Categorical data were presented as absolute and relative frequencies. Quantitative data were showed as mean and standard deviation and the normality of distribution was verified with Kolmogorov-Smirnov (KS) test. Biochemical measures of estradiol and follicle-stimulating hormone (FSH) were transformed to log10. ANOVA with Tukey post-test for comparison of variables between the groups pre, peri and post-menopausal was performed and then multiple linear regression analyzes. Results: Two hundred and seventy eight women aged 50.2 (±5.58) years composed this study, being 50 women in premenopausal status (18%), 122 in perimenopausal (43.9%), and 106 postmenopausal stage (38.1%). The groups were different in age (p=0.001), marital relationship duration (p <0.001), number of pregnancies (p=0.001) and parity (p=0.001). Differences in biochemical measures were observed among the groups: estradiol (p<0.001), FSH (p<0.001), total cholesterol (p=0.001). There were no differences in gait velocity between menopausal status. Values in mean of grip strength decreased by postmenopausal women to perimenopausal and premenopausal ones (24.5 ± 5.1, 25.6 ± 5.4, 26.9 ± 4.9 for post-stage, pre and peri menopausas, respectively, p = 0.02) and the performance of chair stands test was better in premenopausal women compared with that in peri and postmenopausal status (p = 0.02). In multiple linear regression for muscle strength, the variables that remained were: age, estradiol and somatic symptoms measured by Menopause Rating Scale-MRS (R2=0.15). While for the xiv chair-stands test the predictors were number of births and FSH values (R2=0.04). Conclusion: There is a relationship between the stages of menopause and muscle performance in measures of grip strength and sit-up test and these are influenced by the fall of estrogens levels. Data suggest that the decrease in muscle strength and physical performance already appear in the transition to menopause stage, pointing to the need for more research in this area and appropriate preventive interventions

Desigualdade regional da mortalidade neonatal no Brasil

In Brazil, despite the decline in infant mortality in recent decades it still has high rates going against recommended by WHO. Being the largest percentage of infant mortality rate composed of neonatal deaths. Objective: A study was conducted to analyze the spatial distribution of neonatal mortality and its correlation with the biological, socioeconomic and maternal and child health care in the Brazilian states in the period from 2006 to 2010. Method: The study made thematic maps and correlation (LISA) for verification of spatial dependence and multiple linear regression models. Results: Was found that there is no spatial autocorrelation for neonatal mortality in the Brazilian states (R = 0.002, p = 0.48). Most of variables were correlated (r> 0.3, p <0.05) with neonatal mortality, forming clusters in the North and Northeast, with the highest rates of teenage mothers, low household income per capita, lower prenatal appointments and beds of Neonatal Intensive Care Unit. The number of Neonatal UCI beds remained independent effect after regression analysis. Conclusion: The study concludes that regional inequalities in living conditions and especially the access to maternal and child health services contribute to the unequal distribution of neonatal mortality in Brazil

Prevalência de incontinência urinária e fatores associados em idosos institucionalizados

Urinary incontinence (UI) is a geriatric syndrome that is especially prevalent in institutionalized individuals, and that causes economic and social impacts derived from treatment costs and overload of caregiver. UI also entails physical consequences to the health of the elderly, such as urinary tract infections or pressure ulcers, among other health problems. However, the existing national research on this condition is still scarce and comprises serious methodological biases. Therefore, the objective of this study is to determine the prevalence of urinary incontinence and associated factors in institutionalized elderly. A cross-sectional study is presented herein, conducted between October and December, 2013 and carried out in 10 nursing homes in the city of Natal (Northeast Brazil). UI was verified through the program Minimum Data Set version 3.0, which was also used to assess fecal incontinence, urinary devices and UI control programs. Data collection included sociodemographic information, UI characterization, as well as variables related to the institution itself and to health conditions (comorbidities, medication, pelvic floor surgery, Barthel Index for functional capacity and Pfeiffer test for cognitive status). Bivariate analysis was performed using the Chi-Square Test (or Fisher‟s Exact Test) and the Linear Chi-Square Test, calculating the prevalence ratio with 95% confidence interval. Variables with p value under 0.20 were included in the multivariate analysis, which was performed using the Stepwise Forward logistic regression. The inclusion of variables in the final model depended on the likelihood ratio test, absence of multicollinearity and on the Hosmer-Lemeshow test. A statistical significance level of 0.05 was considered. Six (1.8%) hospitalized elderly, one individual in palliative care (0.3%) and one (0.3%) individual under the age of 60 were excluded from the study. The final sample consisted of 321 elderly, mostly females, with a mean age of 81.5 years. The prevalence of UI was 59.43% and the final model revealed statistically a significant association between UI and white race, physical inactivity, stroke, mobility constraints and cognitive decline. The most frequent UI type was functional UI due to physical or cognitive disability, and incontinence control measures were applied only to a minority of residents (approximately 8%). It is concluded that UI is a health issue that affects more than half of the institutionalized elderly, and is associated with white race, physical inactivity, stroke and other geriatric syndromes such as immobility and cognitive disability. Most of these associated factors are modifiable and therefore the findings of this study highlight the importance of UI prevention and treatment in nursing homes, which include general measures, such as physical and psychosocial activities, and specific measures, such as prompted voiding

Evolution of representation of the hands in plastic arts

A interação entre arte e ciência foi intensa durante o Renascimento, sofrendo declínio nos anos posteriores com retomada significativa no século XX, principalmente com o uso de técnicas de identificação, datação de obras de arte e o desenvolvimento de novos materiais. O relacionamento entre artes plásticas e Cirurgia da Mão mantêm-se intenso , sendo freqüente o uso de reproduções artísticas da mão nas ilustrações de textos científicos. Objetivando compreender o papel da mão nas artes plásticas, reproduções de obras de artes (esculturas e pinturas) representativas de vários estilos ou períodos da história da arte foram analisadas com enfoque no estudo das mãos. Detalhes anatômicos, relacionamento com outras estruturas do corpo humano, papel na composição e aspectos simbólicos das mãos foram estudados no contexto histórico e artístico de obras de arte do período paleolítico (pré-história) até o século XX. A representação da mão nas artes plásticas está diretamente relacionada ao estilo ou período da obra e à capacidade individual de interpretação e execução do artista.

Urbanização turística em ponta negra: relações de força e processos sociais no período de 1979-2009

This master thesis aimed to investigate how the power relations operating in the tourism social processes, have shaped the urbanization of Ponta Negra district, Natal, Rio Grande do Norte - RN. The study assumes that the production of space is the result of global phenomena individualized by local forces a process of glocalization. The method used was the case study. It used primary and secondary data and information were treated using the technique of content analysis. The urbanization of Ponta Negra is inserted in the context of global process triggered in the 1970s. The Park of Dunas and Costeira Highway (PD/VC) urbanization project marks the beginning of the Tourisms since 1979. The period in focus was 1979 to 2009. The tourism was dived into four major sections time: tourism in Natal before the Coastal Highway (1939-1979); Project Parque das Dunas / Coastal Highway to the first boom in domestic tourism (1979 - 1990); the internationalization of tourism (1991-2000) and, of first "boom" to "decline" of international tourism (2001-2009). Based on the historical evolution of the tourism were elected three different social processes, able to demonstrate how relations of social forces brought in space act on them and help shape the process of urbanization of the neighborhood in question: The removal of beach hut , the soccer field Botafogo Football Club and the skyscrapers . Finally, it should summarize the research identified interests and conflicts among the actors that form the thrust of spatial transformations: cultural conflicts resulting from the imposition of social practices that differ from the taste of native; clashes between different groups that reflect the duality between use value and exchange value; and interests in land values. In addition, demonstrated that the social relations that involve the production of the area are stimulated by deep-seated societal processes historically and camouflaged by market relations and a modern facade that the city has acquired in recent times; revealed that the actors are linked in networks to increase their influence and that this influence varies mainly according to economic and political power that they or their associates hold

Cultivo de algas marinhas como desenvolvimento de comunidades costeiras

In northeastern Brazil, the extraction of agar has increased considerably in recent decades mainly using macroalgae of the genus Gracilaria. The pressure of the harvest of seaweed of this genus has compromised the sustainability of this natural resource. Given the current framework of decline in production of algae in the state of Rio Grande do Norte, it is necessary the deployment of crops that will assist in the development of coastal areas. This research aimed to develop studies on growth, productivity, efficiency and quality of agar of G. birdiae so as to provide subsidies for crops on commercial scale. The study was carried out in dry and rainy periods using rafts of cultivation. Algal biomass and the physical and chemical parameters of water were measured every fifteen days. In laboratory, the resistance and quality of agar were analyzed. The relative growth rate (TCR) was determined by the formula: RGR = ln (final weight / weight initial). 100 / interval time of sampling. During the study, environmental factors as salinity and temperature remained relatively constant (around 35 PSU and 28°C, respectively). The mean values of biomass ranged around 1952.67 ± 576g in the rainy period and 1925.67 ± 450g in the dry period, and they presented no significant variations. The maximum value of growth (TCR) was recorded in the dry season (7.45%.day-1), with an average over the study of 4.35%.day-1. The yield of agar ranged from 22% to 15%, and its resistance ranged from 850 to 650g. cm². The average obtained for the two periods was approximately 750 g cm². These results demonstrate the great potential of Gracilaria birdiae for mariculture can be used as an sustainable activity for coastal communities

Influencia do turismo sobre a atividade pesqueira do município de Tibal do Sul-RN

A área da pesquisa localiza-se no município de Tibau do Sul, situado na costa leste do Estado do Rio Grande do Norte, a 80 km ao Sul da capital Natal. O turismo, a pesca esportiva e instalação de empreendimentos vêm aumentando nessa área litorânea, disputando espaços com pescadores artesanais. A dissertação teve como objetivo identificar e analisar os conflitos socioeconômicos e ambientais entre a atividade pesqueira e a atividade turística no Município de Tibau do Sul, para subsidiar órgãos governamentais e entidades ligadas ao setor pesqueiro, com futuras políticas de incentivo e desenvolvimento sustentável local. O presente trabalho está dividido em introdução e dois capítulos. A introdução apresenta proposta e justificativa da pesquisa, com fundamentação teórica, em seguida são apresentados os procedimentos metodológicos. O primeiro capítulo apresenta a caracterização da pesca artesanal e o perfil socioeconômico dos pescadores de Tibau do Sul, identificando os conflitos entre a atividade pesqueira e o turismo. Para alcançar esse propósito, foram realizados levantamentos qualitativos e quantitativos, através da efetivação de 100 entrevistas com questionários semiestruturados, os quais foram aplicados a quatro comunidades pesqueiras. Os resultados constataram a real situação da pesca artesanal local e foram identificados vários conflitos, dentre eles: a falta de investimento no setor, baixo desenvolvimento tecnológico e de infraestrutura, além da ocupação desordenada em área de desembarque da produção. Todos esses fatores têm contribuído para o declínio da atividade pesqueira nesse município. O segundo capítulo apresenta uma análise territorial a partir da elaboração do mapa de ocupação do solo utilizando a metodologia de geoprocessamento. Constatou-se que a ocupação desordenada ocorreu principalmente depois da chegada dos turistas em Tibau do Sul e está concentrada principalmente na praia de Pipa, observou-se também que os empreendimentos construídos na área de estudo interferem no acesso público as praias e área de desembarque da produção dos pescadores. Espera-se que este estudo contribua para elaboração do plano de manejo nas comunidades pesqueiras e possa subsidiar os gestores na implementação de políticas públicas voltadas para o desenvolvimento sustentável local

Agroindústria canavieira e unidade de conservação: Impactos Sociais na comunidade de pescadores de Baía Formosa (RN)

The conservation unities emerged in response to the environmental damages. In the Atlantic Forest of the Brazilian Northeast, the most of the damages come from the sugar-cane agro-industry, especially by the deforestation for the introduction of sugar-cane fields and installation of the industry structure. Besides the damages over the biodiversity, there are critical social problems that affect the communities which survive using directly or indirectly the biome from the Atlantic Forest. The objective of this research is to analyze the social impacts on the fishermen of Baía Formosa/RN generated by the changes and socio-environmental transformations occurred starting the installation of a sugar-cane factory and the creation of a conservation area in the municipality of Baía Formosa/RN community. The research is based on a qualitative and diachronic perspective, for both approach, it was used the method of oral history in conjunction with the literature search and some technical and research tools such as direct observation, interview, records images and recordings . The results show that social and symbolic practices of the community in the conservation unit Mata Estrela last more strongly presented. Today fewer natural resources are used, due to factors such as limit access to forest and disappearance of some natural resources by deforestation. It is believed that the loss of free access to space for the community is the most significant negative impact, as promoted changes in the relationship of the community with the Star Forest that contributed to the fading of their social and symbolic practices. The loss of free access caused the decline in the practice of agriculture, which resulted in the loss of one of the means of social reproduction of the community

Caracterização tectono-estratigráfica da sequência transicional na sub-bacia de Sergipe

This thesis deals with the tectonic-stratigraphic evolution of the Transitional Sequence in the Sergipe Sub-basin (the southern segment of the Sergipe-Alagoas Basin, Northeast Brazil), deposited in the time interval of the upper Alagoas/Aptian stage. Sequence boundaries and higher order internal sequences were identified, as well as the structures that affect or control its deposition. This integrated approach aimed to characterize the geodynamic setting and processes active during deposition of the Transitional Sequence, and its relations with the evolutionary tectonic stages recognized in the East Brazilian Margin basins. This subject addresses more general questions discussed in the literature, regarding the evolution from the Rift to the Drift stages, the expression and significance of the breakup unconformity, the relationships between sedimentation and tectonics at extensional settings, as well as the control on subsidence processes during this time interval. The tectonic-stratigraphic analysis of the Transitional Sequence was based on seismic sections and well logs, distributed along the Sergipe Sub-basin (SBSE). Geoseismic sections and seismic facies analysis, stratigraphic profiles and sections, were compiled through the main structural blocks of this sub-basin. These products support the depositional and tectonic-stratigraphic evolutionary models built for this sequence. The structural analysis highlighted similarities in deformation styles and kinematics during deposition of the Rift and Transitional sequences, pointing to continuing lithospheric extensional processes along a NW trend (X strain axis) until the end of deposition of the latter sequence was finished by the end of late Aptian. The late stage of extension/rifting was marked by (i) continuous (or as pulses) fault activity along the basin, controling subsidence and creation of depositional space, thereby characterizing upper crustal thinning and (ii) sagstyle deposition of the Transitional Sequence at a larger scale, reflecting the ductile stretching and thinnning of lower and sub crustal layers combined with an increasing importance of the thermal subsidence regime. Besides the late increments of rift tectonics, the Transitional Sequence is also affected by reactivation of the border faults of SBSE, during and after deposition of the Riachuelo Formation (lower section of the Transgressive Marine Sequence, of Albian age). It is possible that this reactivation reflects (through stress propagation along the newlycreated continental margin) the rifting processes still active further north, between the Alagoas Sub-basin and the Pernambuco-Paraíba Basin. The evaporitic beds of the Transitional Sequence contributed to the development of post-rift structures related to halokinesis and the continental margin collapse, affecting strata of the overlying marine sequences during the Middle Albian to the Maastrichtian, or even the Paleogene time interval. The stratigraphic analysis evidenced 5 depositional sequences of higher order, whose vertical succession indicates an upward increase of the base level, marked by deposition of continental siliciclastic systems overlain by lagunar-evaporitic and restricted marine systems, indicating that the Transitional Sequence was deposited during relative increase of the eustatic sea level. At a 2nd order cycle, the Transitional Sequence may represent the initial deposition of a Transgressive Systems Tract, whose passage to a Marine Transgressive Sequence would also be marked by the drowning of the depositional systems. At a 3rd order cycle, the sequence boundary corresponds to a local unconformity that laterally grades to a widespread correlative conformity. This boundary surface corresponds to a breakup unconformity , being equivalent to the Pre-Albian Unconformity at the SBSE and contrasting with the outstanding Pre-upper Alagoas Unconformity at the base of the Transitional Sequence; the latter is alternatively referred, in the literature, as the breakup unconformity. This Thesis supports the Pre-Albian Unconformity as marker of a major change in the (Rift-Drift) depositional and tectonic setting at SBSE, with equivalent but also diachronous boundary surfaces in other basins of the Atlantic margin. The Pre-upper Alagoas Unconformity developed due to astenosphere uplift (heating under high lithospheric extension rates) and post-dates the last major fault pulse and subsequent extensive block erosion. Later on, the number and net slip of active faults significantly decrease. At deep to ultra deep water basin segments, seaward-dipping reflectors (SDRs) are unconformably overlain by the seismic horizons correlated to the Transitional Sequence. The SDRs volcanic rocks overly (at least in part) continental crust and are tentatively ascribed to melting by adiabatic decompression of the rising astenospheric mantle. Even though being a major feature of SBSE (and possibly of other basins), the Pre-upper Alagoas Unconformity do not correspond to the end of lithospheric extension processes and beginning of seafloor spreading, as shown by the crustal-scale extensional structures that post-date the Transitional Sequence. Based on this whole context, deposition of the Transitional Sequence is better placed at a late interval of the Rift Stage, with the advance of an epicontinental sea over a crustal segment still undergoing extension. Along this segment, sedimentation was controled by a combination of thermal and mechanical subsidence. In continuation, the creation of oceanic lithosphere led to a decline in the mechanical subsidence component, extension was transferred to the mesoceanic ridge and the newly-formed continental margin (and the corresponding Marine Sequence) began to be controlled exclusively by the thermal subsidence component. Classical concepts, multidisciplinary data and new architectural and evolutionary crustal models can be reconciled and better understood under these lines

Acari-RN: da construção do território aos limites da pobreza

Acari-RN is one of the earliest municipalities in the region of Seridó Potiguar in rio Grande do Norte. In this municipality, two feelings coexist: power and loss. The former, justified by the process of occupation, which gave birth to its micro-region and the latter, marked by economic impoverishment, starting from the decade of 1970, with the decline of its main wealth: the cotton economy. From the association of these feelings, the motivation for the construction of this piece of work emerged. In it, poverty and inequality are discussed, in a dialect relation with the territory, through a theoretical-methodological reflection and from the analysis of the data collected in a field research. In order to valorize and enrich the theme and the study of the territory of Acari, it was necessary to compare it with the other municipalities that it generated: Currais Novos, Jardim do Seridó and Parelhas. Therefore, the use of the elements of a quantitative and qualitative research, applied in the study section, aimed at finding the poverty indicators, which make it difficult the development in Acari.

Características das Curvas de Regressão da Gonadotrofina Coriônica Pós-mola Hidatiforme Completa

Objetivos: construir a curva de regressão do b-hCG pós-mola hidatiforme completa (MHC) com remissão espontânea e comparar com a curva de regressão pós-MHC com tumor trofoblástico gestacional (TTG). Análise comparativa da curva de regressão do b-hCG das portadoras de MHC, acompanhadas no Serviço, com a curva de regressão observada por outros autores1-3. Métodos: foi realizada avaliação clínica e laboratorial (dosagem sérica de b-hCG), na admissão e no segmento pós-molar, de todas as pacientes com MHC, atendidas entre 1990 e 1998 no Hospital das Clínicas de Botucatu - Unesp. O resultado da determinação seriada do b-hCG foi analisado em curvas log de regressão. A evolução da curva de regressão do b-hCG foi analisada e comparada em MHC com remissão espontânea e MHC com TTG numa curva log de regressão, com intervalo de confiança de 95%. A curva log de regressão do grupo de remissão espontânea foi comparada com curvas consideradas padrão1,2. Foram construídas curvas log individuais de todas as pacientes e classificadas de acordo com os quatro tipos de curva (I, II, III e IV), propostos para o seguimento pós-molar³. Resultados: 61 pacientes com MHC tiveram seguimento pós-molar completo, 50 (82%) apresentaram remissão espontânea e 11 (18%) desenvolveram TTG. No grupo de pacientes com MHC e remissão espontânea, o tempo para alcançar a normalização dos níveis do b-hCG, após o esvaziamento molar, foi até 20 semanas. As pacientes que desenvolveram TTG apresentaram desvio precoce da curva de regressão normal do b-hCG, 4 a 6 semanas após o esvaziamento molar. Nestas pacientes, a quimioterapia foi introduzida em média na 9ª semana pós-esvaziamento molar. Conclusões: a curva de regressão do b-hCG pós-MHC com remissão espontânea apresentou declínio log exponencial, semelhante ao observado por outros autores1,2, e diferente das MHC com TTG. Foram identificados três tipos de curvas de regressão do b-hCG, semelhantes aos de Goldstein³, I, II e IV, e outros dois tipos diferentes de regressão do b-hCG: V (regressão normal) e VI (regressão anormal).

Aspectos epidemiológicos da tuberculose pulmonar nos municípios de Botucatu, Conchas, São Manuel e Avaré, Estado de São Paulo, Brasil, de 1963 a 1972

O diagnóstico da situação da tuberculose pulmonar nos Municípios de Botucatu, Conchas, São Manuel e Avaré, SP, Brasil, baseou-se na prevalência e risco de infecção em escolares de lª série, em 1972, e em dados de morbidade e mortalidade específica, de 1963 a 1972. Realizou-se inquérito tuberculínico em 2.913 escolares, com PPD 23 RT-2UT; foram analisados os prontuários de 718 casos inscritos no CSI de Botucatu e os atestados de óbito de residentes, incluindo-se os ocorridos em hospitais especializados. As taxas de prevalência de infecção para os quatro Municípios foram respectivamente 2,4%; 6,8%; 1,9% e 4,5%. Para a idade de 7,5 anos, os riscos de infecção foram: 0,27%; 0,32; 0,20% e 0,34%. O nível de infecção apurado caracterizou o conjunto como área de média prevalência da tuberculose pulmonar. Os índices de prevalência de infecção relacionaram-se diretamente à incidência de casos bacilíferos de cada Município. em 530 casos com baciloscopia, houve 62,0% de positividade. As formas radiológicas moderada e avançada predominaram principalmente em adultos jovens do sexo masculino. Foram registradas alta taxa de abandono (39,5%}, baixo percentual de cura (17,9%) e 3,4% de óbitos; ao redor de 32,0% estava em tratamento. Não houve diferenças estatisticamente significativas das proporções de abandono, segundo procedência por Município ou formas da doença. Invocaram-se razões técnico-administrativas do sistema vigente para explicar esses achados. A incidência média de casos confirmados, no período, foi de 35,4 em Conchas, 33,1 em Avaré, 23,7 em Botucatu e 18,5 em São Manuel (por 100.000). Com casos confirmados e suspeitos os índices foram: 57,6; 48,8; 43,8 e 35,3. Os índices médio-anuais de mortalidade, foram: 7,6 em Botucatu, 12,14 em Conchas, 5,0 em São Manuel e 18,7 em Avaré (por 100.000). Apenas em Botucatu registrou-se declínio das taxas de mortalidade de 1963 a 1972. A mortalidade específica em adultos jovens ainda era elevada, predominando no sexo masculino, principalmente em Conchas. Sublinhou-se a necessidade de descentralizar as atividades antituberculose para atingir um controle eficiente.

Perfil de aglutininas anti-Leptospira em bezerras búfalas vacinadas com bacterina pentavalente comercial contra leptospirose

Avaliou-se o perfil sorológico de 17 bezerras búfalas vacinadas nos dias zero, 30 e 210 com bacterina pentavalente comercial contra leptospirose, empregando-se a prova de soroaglutinação microscópica com antígenos vivos, durante o período de 360 dias. Utilizaram-se quatro bezerras-controle, e todos os animais foram negativos no dia zero. Nos animais vacinados, foram observadas reações aos 60 dias para todos os sorovares, associadas a títulos máximos para Canicola, Grippothyphosa e Pomona. No 90° dia, houve declínio acentuado dos títulos para todos os sorovares e ausência de títulos para Hardjo. Nos dias 120º, 150º, 180º e 210º, ocorreram oscilações de títulos para todos os sorovares. No 240º dia, foram encontrados títulos máximos para Hardjo, elevação para os outros sorovares e ausência de título para Canicola. Nos dias 270º, 300º e 330º, foi observado declínio gradativo dos títulos. No 360º dia, foram encontrados títulos residuais para Icterohaemorrhagiae, Grippothyphosa e Pomona e ausência de reação para os outros sorovares. Inferiram-se a reduzida persistência dos títulos vacinais mesmo após o reforço e revacinação e a baixa interferência da vacinação no diagnóstico sorológico.
