Physiological changes induced by the aging process is dynamic and progressive, reducing the adaptability and independence of older people and may be influenced by genetic and environmental factors. Thus the aim of this thesis was to investigate the association between polymorphism of the ACE gene ID and the phenotypes of muscular strength and blood pressure of 62 elderly Brazilian (67.35 ± 5.66 years) during a 16-week program of supervised training. The elderly women were stratified by age, with the group 1 (G1, n = 34) <70 years and group 2 (G2 n = 28) ≥ 70 years, and in three groups by ACE, ACE-II (n = 8) ACE- DD (n = 35) and ACE-ID (n = 19). The level of muscle strength was evaluated by the method of maximum repetitions and measures of blood pressure (BP) were measured before and after training (PAPré1 and PAPós1) and before and after each training session (PAPre2 and PAPós2), in place of training. DNA samples were isolated from peripheral blood leukocytes polymorphism and insertion / deletion (ID) of the ACE gene (rs1800795) was genotyped by polymerase chain reaction (PCR) plus PCR-confirmatory. The genotype distribution of the polymorphism ID attended the prerogatives of Hardy-Weitíherg. There was variation in power levels before and after training and the age between groups (t-test) and the ACE polymorphism (ANOVA) (p <0.05). Depending on the results it was concluded that resistance training helps to reduce SBP and increased muscle strength of upper and lower limbs when considering the age and ACE polymorphism. In this study the Elderly carriers of the D allele were more reactive to changes in BP resistance training. This study was multidisciplinary project involving researchers in the areas Medical, Physical Education, Pharmacy, Nutrition, Gerontology and Statistics. This fulfilled the requirements of the multidisciplinary Graduate Program in Health Sciences

Enterocutaneous fistulas are associated with prolonged hospital stay, high morbidity/mortality, and increase in hospital costs. This study aims to describe the use of a vacuum system and normal oral diet in dealing with this problem. Methods: Seventy-four consecutive patients with recent and defined external postoperative fistulas were analyzed. Abdominal imaging was used to exclude abscess and distal obstruction. The fistula tract was sealed with Foley catheter, connected to a negative pressure flask, changed daily for 5, 10 or 15 days, as necessary. Normal oral diet was permitted. Results: No patient died. Serum albumin and transferrin showed significantly higher levels at the end of treatment than at the beginning. The moderate and low-output fistulas had the best results (97% closed). Forty-eight (65%) fistulas closed after five days, 16(22%) after 10 days and 4(5%) after 15 days. Treatment failed in 6(8%) patients, who subsequently underwent surgery. Only one patient with low-output did not close her fistula. The cost of the treatment was US$ 41.75/day and it was considered cost effective. Conclusions: The vacuum system demonstrated good results in the treatment of fistulas. It included simplicity, low cost, short hospital stay, absence of skin breakdown, normal eating, good nutrition and activity patterns

Avaliar fatores de risco cardiovascular em mulheres brasileiras com síndrome dos ovários policísticos (SOP), através da utilização de múltiplos parâmetros, incluindo a determinação da prevalência de síndrome metabólica e seus componentes e pesquisa de microalbuminúria como marcador de um possível dano renal precoce nessas pacientes. Métodos: Foram avaliadas 102 mulheres de 20-34 anos de idade, com diagnóstico de SOP pelo Consenso de Rotterdam, tendo sido analisados parâmetros clínicos, antropométricos, bioquímicos e hormonais. Para diagnóstico de síndrome metabólica, foram adotados critérios do National Cholesterol Education Program s Adult Treatment Panel III (NCEP-ATP III). Para avaliação da microalbuminúria foi utilizada a relação albumina/creatinina (A/C), calculada a partir dos níveis de albumina e creatinina em amostra isolada de urina. Foram realizados testes estatísticos para avaliar associações e correlações entre variáveis, bem como comparação de médias ou medianas, adotando-se nível de significância de 5%. Resultados: A prevalência de síndrome metabólica foi de 28,4% (29 em 102 pacientes), estando associada ao aumento do índice de massa corporal (IMC). Quanto à análise da prevalência dos componentes individuais da síndrome metabólica, evidenciou-se: HDL-colesterol < 50 mg/dl em 69,6%, circunferência da cintura ≥ 88 cm em 57,9%, triglicerídeos ≥150 mg/dl em 31,7%, pressão arterial ≥130/85 mmHg em 18,6% e glicemia de jejum ≥110 mg/dl em 2,9%. Quando definida pelos limites convencionais para a relação A/C (3,5 35 mg/mmol), a microalbuminúria esteve presente em apenas três pacientes (3,3%). Entretanto, considerando diferentes limites de corte estabelecidos em recentes estudos que demonstraram aumento do risco cardiovascular associado a níveis muito baixos da relação A/C, a prevalência em mulheres com SOP foi alta, variando de 17,7 a 43,3% (para valores ≥ 0,58 e ≥ 0,37 mg/mmol, respectivamente). Mulheres com intolerância à glucose apresentaram nível significativamente mais elevado da relação A/C, quando comparadas às mulheres com normoglicemia. Os valores de microalbuminúria não apresentaram correlação significativa com IMC, níveis pressóricos, índices de sensibilidade insulínica ou perfil lipídico. Conclusões: Os dados evidenciam uma alta prevalência de síndrome metabólica e seus componentes individuais em mulheres brasileiras com SOP. Além do mais, observou-se elevado percentual de mulheres com níveis de excreção urinária de albumina em faixas significativamente associadas com aumento do risco para eventos cardiovasculares. Em conjunto, esses dados alertam para a necessidade da abordagem interdisciplinar e multidisciplinar das pacientes com SOP, visando à instituição de medidas voltadas para a prevenção primária cardiovascular

This study had as objective to identify to the perception of mothers and professionals of health on the attention to the health of HIV-Positive children/adolescents in the city of Natal-RN. It is a descriptive-exploratory study with quantitative and qualitative approach, carried through in the Giselda Trigueiro Hospital and in the State and Municipal Health Councils in Natal - RN, from march to december of 2005. The sample was composed by 56 participants, 33 mothers of children who use specialized assistance and 23 professionals. Data collection occurred with the application of a half-structuralized interview. Quantitative data were analyzed through descriptive statistics and qualitative data were submitted to content analysis. Prevailing categories in relation to the cartography of the attention to seropositive children and adolescents in Natal were: Organization and dynamics of the attention; Institutional management and human development; Control and prevention; other contexts of attention; relationship/communication team-patient and organization and functioning of the services. The profile epidemiologist of the children, adolescents and of the people/mothers, who take care of them with HIV/Aids, followed the evolution of the epidemic in the country and the world. It was verified that mothers need care and information; however they make a positive evaluation of the attendance they receive. It was also observed many gaps in the services of assistance, in which the researched group was attended, beyond imperfections in the communication between health professionals and users. The professionals recognize the advances that the politics represent for the assistance of people with Aids; however feel themselves limited by the precariousness of the system and the partner-economic conditions of the people. According to these data, it can be verified great challenges to go through in the context of integrality of the assistance to HIV positive children and adolescents in the city of Natal and in the improvement of the communication in the institution of reference

Rio Grande do Norte is among the Brazilian States where the tourism and sexual violence increasingly grow in the country, occupying 4th place in 2004. Associated to this fact, it comes the problematic one of the contamination of the women by Sexually Transmitted Disease (STD). Studies in Brazil have presented a considerable increase of the STDs, caused through lack of suitable protection in the sexual relationships. Due to the biological and psychosocial vulnerability, besides failures or inconsistencies in the condom use associated to the raised taxes of sexual activity with different partners, the STDs constitute the main risk of health. Many difficulties are found by the confrontation of this problem. In this context, this project had as aim to evaluate the vulnerability of this population of sexually active women in Natal-RN Ponta Negra neighbourhood to the infections by STDs, such as, Candida sp., Vaginoses Bacterial, Trichomonas Vaginalis and Chlamydia sp., arisen with the explosion of the sex market, showing a current statistical panorama. It was possible to detect vulnerable points in prevention through patient anamnesis, where the study it showed: high number of partners (8,3% with more than five), low age of first relationship and not the use of condoms (31,8% sometimes use and 45,8% had not used in the first relationship). Already consolidated by the preventive cytopathologic examination, these data were strengthened by high incidence of causing agents of STDs (58,6%). In this way, it is clear that the sexuality must to be thought on the context of the deep economic and socio-cultural transformations in which pass societies, and mainly the ones concerning to the sexuality exercise and to the sex market. With the profile change of the infections, new demands are placed in relation to the risk factors. Therefore, it can be concluded that the prevention vulnerable points detected as more important had been the deficiency in self-perception and wareness of the risk existence among the studied women

Estudos em animais de laboratório sugerem um efeito antiulcerogênico do extrato de Casearia sylvestris. Esse extrato ainda não foi estudado para a profilaxia e/ou o tratamento de úlceras gástricas em equinos. Para avaliar a influência do extrato de C. sylvestris na permeabilidade gástrica à sacarose, seis equinos adultos foram submetidos a modelo de indução de úlceras gástricas. Os animais foram submetidos ao teste de permeabilidade à sacarose antes e ao término do protocolo de restrição alimentar intermitente, para detecção de ulceração gástrica. Durante os sete dias da indução, os animais foram submetidos a tratamentos diários via sondagem nasogástrica com extrato de C. sylvestris (9mg kg-1 de peso corpóreo) ou veículo (ágar). Após intervalo de 32 dias em piquete, para permitir a cicatrização das úlceras induzidas, cada animal foi submetido novamente ao protocolo de indução de úlcera gástrica, e os tratamentos foram alternados. Dessa forma, cada animal foi submetido a ambos os tratamentos em períodos distintos. A concentração de sacarose na urina foi determinada para cada amostra obtida, por cromatografia líquida de alto desempenho e detecção amperométrica pulsátil. Não foram observadas alterações nos exames clínicos e hemogramas. O tratamento com o extrato de C. sylvestris evitou o aumento da concentração de sacarose urinária (P<0,05) quando comparado ao veículo, sugerindo um efeito antiulcerogênico gástrico em equinos. Estudos mais amplos incluindo gastroscopia são necessários para avaliar a possibilidade de usar o extrato para a profilaxia e/ou o tratamento das úlceras gástricas em equinos.

The aging population and individual have been the subject of a multitude of studies nowadays. This is probably due to the impact of this phenomenon in various sectors of society, like social security, social assistance and public health. The process of aging of the individual imply the demand for specific services, considering the limitations and vulnerabilities of the individual at that stage of life cycle. The growth of the elderly contingent in the last decades raises challenges for policymakers, the family and also for the society at large. In this scenario, long-stay institutions for the elderly (LSIEs) appear as an option to aid and support the elderly and their family, assisting in all or part in the activities of daily living and self-care. Inside these LSIEs we find the professional responsible for the direct care of the elderly, the formal caregiver. In this context, this dissertation presents two main objectives: an analysis of the phenomenon of population aging in a given brazilian municipality Natal / RN, based on the Demographic Censuses of 2000 e 2010; and a social, demographic and economic characterization of the Formal caregiver for the institutionalized elderly in the municipality, evaluating aspects of his quality of life and also analyzing the institutions where they are inserted. Furthermore, we intend to identify demographic, socioeconomic and quality of life factors that are correlated with caregivers quitting the job. The data used in the second part of this work comes from the research project named Long-Stay Institutions for Elderly: abandonment or a family need? . This survey interviewed 92 caregivers in eleven LSIEs in Natal/RN. In the data treatment logistic regressions, cluster analysis and statistical tests were used. The survey revealed that aging in Natal is more pronounced in the older, more traditional districts: Petrópolis, Lagoa Seca and Tirol. It also allowed a broad characterization of the formal caregivers in LSIEs. Most of these professionals are female. The educational level is predominantly complete high school and more. Most caregivers reported being married or in union, or have ever been in a union. Family monthly income is under three times the minimum wage. The mean age is of 37.4 years. The mean time of work as a caregiver was 5.93 years. The associations showed that being woman, not being single, having caregiving training and physical limitations (regarding quality of life) are related to wanting to quit the caregiving job. As for the characterization of the LSIEs, it was found that the philanthropic ones are older and have most (62.5%) of the institutionalized elderly. The institutions managers gave social interaction and affinity with the elderly as the main criteria with which to evaluate and hire caregivers. It is intended with this study to contribute to improving the quality of life of the elderly and their caregiver, providing information on aspects of institutionalization of elderly both in the philanthropic and particular institutions, in Natal/RN; this dissertation may also be used as a starting point for later works

O adequado manejo de culturas de cobertura no plantio direto tem-se mostrado excelente alternativa para melhorar as condições de semeadura. O objetivo do presente trabalho foi avaliar o desempenho do trator agrícola no manejo dos restos culturais do sorgo (rolo-faca e triturador de palhas) e a pressão de inflação (525 e 385 kPa) do pneu da semeadora-adubadora, no estabelecimento da cultura do milho em plantio direto. O experimento foi conduzido na UNESP - Jaboticabal, em delineamento de blocos ao acaso, com parcela subdividida, e os tratamentos consistiram nos manejos da cultura de cobertura do solo e pressões de inflação do pneu da semeadora, com quatro repetições. Foram mensurados nas máquinas: velocidade de deslocamento, capacidade de campo, consumo de combustível e patinhagem do trator; no solo e nas plantas, foi acrescido o tratamento de manejo com herbicida: cobertura inicial, número de dias para emergência das plântulas, população inicial e final de plantas, distribuição longitudinal e produtividade de grãos. No manejo da palhada da cultura do sorgo, o rolo-faca proporcionou maior capacidade de campo e menores consumos de combustível. Os tratamentos manejos e pressão não interferiram na cobertura do solo, no número de dias para emergência do milho e na distribuição longitudinal.

As semeadoras-adubadoras, responsáveis pela correta adição de semente e adubo ao solo, possuem mecanismos dosadores acionados por suas rodas motrizes, que giram em função do contato com a superfície do solo. Esse contato é influenciado, entre outros fatores, pela pressão de inflação dos pneus. O objetivo do presente trabalho foi estudar o desempenho de uma semeadora-adubadora de precisão em função do preparo do solo (preparo convencional e plantio direto), das velocidades de deslocamento e da pressão de inflação do seu pneu. O trabalho foi realizado na UNESP de Jaboticabal (SP) no ano de 2006. Foram avaliadas as seguintes variáveis: força de tração e potência na barra, consumo de combustível (horário, ponderal, operacional e específico), capacidade de campo operacional, patinagem dos rodados do trator e da semeadora-adubadora, estande inicial e distribuição longitudinal de sementes. O sistema plantio direto demandou maior força (35 %), potência e consumo horário de combustível; o mesmo aconteceu na maior velocidade. A pressão de inflação das rodas da semeadora proporcionou menor patinagem e maior estande inicial de plântulas.

Bioinseticidas fúngicos são aplicados com pulverizadores convencionais e algumas características destes equipamentos podem não ser adequadas e afetar a eficiência dos bioinseticidas. O objetivo deste trabalho foi verificar se pressões usuais, em aplicações com o pulverizador de barra, podem afetar a ação inseticida de conídios de Beauveria bassiana e Metarhizium anisopliae, componentes de produtos comerciais brasileiros. Para isso, suspensões aquosas de três bioinseticidas foram submetidas à passagem pelo equipamento em três pressões (20, 40 e 60 lbf pol-2) e avaliadas quanto ao rompimento, à viabilidade e à virulência dos conídios. Avaliou-se a viabilidade em lâminas de microscopia cobertas com meio de cultura, após incubação a 26±0,5ºC e fotoperíodo de 12 horas. A concentração foi determinada por meio de contagens em câmara de Neubauer e a virulência foi avaliada para lagartas de Diatraea saccharalis. Não foram encontradas, nos três produtos, influências significativas em nenhum dos parâmetros. Nas pressões avaliadas, a aplicação com o pulverizador de barra não reduz a viabilidade e nem a virulência dos conídios dos bioinseticidas testados, tampouco provoca destruição dos conídios.
