Contributo da Academia Sénior: a força de ir mais além! Um estudo descritivo simples e longitudinal da qualidade de vida do idoso

O aumento do número de idosos com necessidades de ocupação, implica a necessidade de respostas por parte da sociedade, de forma a melhorarem a qualidade de vida da população idosa. O presente estudo, teve como objetivo conhecer os níveis de perceção da qualidade de vida e bem-estar, em indivíduos de terceira idade. Trata-se de um estudo descritivo longitudinal, que resulta da avaliação em dois momentos. Foi estudada uma população com 26 idosos, com idades iguais ou superiores a 64 anos de idade, participantes num projeto educativo de uma academia sénior, com a duração de quatro meses. Foi utilizada a escala EASY-care, para avaliação da qualidade de vida percecionada pelos idosos. Para análise dos dados, utilizou-se o programa estatístico SPSS 19.0. Através dos resultados obtidos, verificou-se que a maioria da população estudada foi do sexo feminino, cerca de 92.3%, e 7.7% do sexo masculino. No que se referiu às idades, 26,9% apresentaram idades compreendidas entre 65-69 anos, 42.3%, entre 70-74 anos, e por fim 30.8% entre 75-80 anos. Sendo na sua maioria, viúva, reformada, pensionista e com fraca escolaridade, entendendo-se que, apenas 57.7% da população apresentou o primeiro ciclo de escolaridade. Os resultados obtidos revelaram-se positivos, uma vez que, os scores médios para cada domínio foram indicadores de independência e elevada qualidade de vida, em ambos os momentos de análise, com valores médios mais elevados no segundo momento. Para os resultados de “(in) dependência”, no primeiro momento, o score médio foi de 2.8. Para o “risco e falha de cuidados”, o score médio foi 3.7, para o “risco de quedas”, o score médio de 0.9. No segundo momento, para “pontuação (in) dependência”, o score médio foi 1.8, para o “risco de falha de cuidados,” de 0.88 e para o “risco de quedas”, de 0.6. No domínio “Visão, Audição e Comunicação”, no primeiro momento, o score médio foi de 0.55. No segundo momento, para o mesmo domínio, o score médio foi de 0.3. No domínio “Saúde Mental e Bem-estar”, no primeiro momento, o score médio foi de 10.7, e no segundo momento de 5.6. Concluiu-se que a perceção da qualidade de vida e bemestar dos idosos, foi elevada nos dois momentos, verificando-se um aumento dos valores absolutos do primeiro para o segundo momento. Ressalvamos a importância da monitorização da qualidade de vida e bem-estar dos idosos, como forma de promoção de uma intervenção adequada às necessidades da população.

Expansiones del híbrido escultura/arquitectura: cartografías de un Arch–Art como respuesta al arte público crítico

El objeto principal de esta tesis doctoral es cartografiar, revisar y proponer el empleo de un género de arte público basado en las relaciones de interferencia entre escultura y arquitectura. Tales relaciones han concebido obras y modelos de fusión entre los dos campos propuestos y para ello se há sugerido el término anglosajón arch–art, según ha sido empleado también por teóricos del tema como Javier Maderuelo y Martí Peran, entre otros. A pesar de ser reconocida y estudiada la relación de ambos campos a lo largo de la historia del arte, se ha dado principal atención a los fenómenos que han enmarcado estas cuestiones en el siglo XX y principalmente se ha dibujado un panorama contemporáneo particularizando las prácticas artísticas de los últimos treinta años y teniendo en cuenta las aportaciones de innovadoras cualidades en la esfera pública de dichos acontecimientos híbridos. Se ha dedicado un estudio exclusivo sobre la aparición de obras destacadas en el contexto que han emergido episódicamente y en distintos escenarios de la creación profesional, dirigida tanto por artistas como por arquitectos, lo que consolida el concepto arch-art como obra artística de características propias, las cuales proponemos como un lenguaje que amplia y extiende el propio concepto de escultura y viceversa. Las características de la ciudad contemporánea han validado el surgimiento de obras híbridas del género arch-art en el espacio público que utilizan la metáfora de la habitabilidad por medio de la funcionalidad y una reflexión sobre sus posibilidades de actuación en el entorno desde un arte público de vertiente crítica.

Estudos e propriedades mecânicas de um novo tipo de bloco cerâmico híbrido para edificações em alvenarias estruturais

This dissertation presents a hybrid ceramic block the use of which reside in the buildings executed with walls. Initially, we conducted a survey on the requirements and / or norms prevailing in Brazil about structural ceramic blocks, making use of the experiences in other countries. This work seeks new materials and / or products in order to maintain or increase the compressive strength of the ceramic blocks, without neglecting the other properties. Then was collected materials (clay and crushed powder) and an approach on the characterization, through fluorescence, Mineralogy, vitrification curve and characterization of these materials used in the manufacture of the blocks by Ray Diffraction "X" and SEM. Subsequently it was made, numbered and measured dimensions of about 150 bodies of the test piece (hybrid ceramic blocks in small sizes) with varying percentages of 0%, 5%, 10% and 15% substitution of crushed clay powder. After sintering of the bodies of the test piece at temperatures of 900oC, 1000oC 1100oC and with a heating rate of 5oC/minuto and level of 1 hour, the samples were submitted to the tests (compressive strength and water absorption) and calculated their retractions, which were subsequently carried out the analysis of the results according to the criteria and parameters required by Brazilian legislation and standards in force

Análise de um queimador infravermelho funcionando com combustível híbrido : GLP/Bio-óleo

Biomass is considered the largest renewable energy source that can be used in an environmentally sustainable. From the pyrolysis of biomass is possible to obtain products with higher energy density and better use properties. The liquid resultant of this process is traditionally called bio-oil. The use of infrared burners in industrial applications has many advantages in terms of technical-operational, for example, uniformity in the heat supply in the form of radiation and convection, with a greater control of emissions due to the passage of exhaust gases through a macroporous ceramic bed. This paper presents a commercial infrared burner adapted with an ejector proposed able to burn a hybrid configuration of liquefied petroleum gas (LPG) and bio-oil diluted. The dilution of bio-oil with absolute ethanol aimed to decrease the viscosity of the fluid, and improving the stability and atomization. It was introduced a temperature controller with thermocouple modulating two stages (low heat / high heat), and solenoid valves for fuels supply. The infrared burner has been tested, being the diluted bio-oil atomized, and evaluated its performance by conducting energy balance. The method of thermodynamic analysis to estimate the load was used an aluminum plate located at the exit of combustion gases and the distribution of temperatures measured by thermocouples. The dilution reduced the viscosity of the bio-oil in 75.4% and increased by 11% the lower heating value (LHV) of the same, providing a stable combustion to the burner through the atomizing with compressed air and burns combined with LPG. Injecting the hybrid fuel there was increase in the heat transfer from the plate to the environment in 21.6% and gain useful benefit of 26.7%, due to the improved in the efficiency of the 1st Law of Thermodynamics of infrared burner

Prevalência da infecção pelo Papilomavírus humano, Chlamydia Trachomatis e Herpes Simples do tipo 2 em adolescentes atendidas em unidades de saúde pública de Natal

This study assessed the level of knowledge, attitude and practice of Pap smear and human papillomavirus (HPV), in addition to analyzing the prevalence of genital HPV infection, Herpes Simplex Type 2 (HSV-2) and Chlamydia trachomatis in teenagers. The study consisted of two approaches, one based only on interviews conducted with adolescents enrolled in public schools or in public health facilities in the city of Natal. The other approach involved only a group of 132 adolescents enrolled among those admitted to two health units in Natal-RN. This second group of participants two specimens were collected for laboratory analysis: one was directed to prepare the blade for the Pap test, and other processed for DNA extraction for molecular analysis, focusing on the detection of HPV, HSV-2 and C . trachomatis. The presence of DNA of the three pathogens was investigated by the technique of polymerase chain reaction (PCR). The presence of each of the three pathogens was analyzed in terms of socio-demographic characteristics, as well as sexual and reproductive activity to identify risk factors for infection and development of lesions of the uterine cervix. The results show that the adolescents in this study had levels of knowledge and attitude very low, both in relation to cytology to HPV as though they have made a reasonable percentage of adequate practice exam and prevention of HPV infection. The overall prevalence of HPV infection was 54.5% and 48.2% in adolescents with normal cytology and 86.4% in those with abnormal cytology. We observed a higher proportion of cases of infection in the age group of 18 to 21. The prevalence of HPV infection was slightly higher among pregnant teenagers. The overall prevalence of HSV-2 infection was 13.6% and 11.8% in women with normal cytology and 22.7% in those with abnormal cytology. A higher proportion of cases of infection was found in the age group from 14 to 17, with a slightly higher prevalence among pregnant women. The C. trachomatis was found with an overall prevalence of 19.7% and 21.8% in adolescents with normal cytology and 9.1% in those with abnormal cytology. The prevailing rate was highest in the age group 18 to 21 years and in nonpregnant

Prevalência da infecção genital pelo vírus herpes simples tipo 1 e 2 em mulheres grávidas e não grávidas de Natal/RN

Herpes simplex is a virus that can be transmitted sexually and is potentially associated with vertical transmission. This study evaluated the prevalence of genital infection by herpes simplex virus (HSV) types 1 and 2 in pregnant and nonpregnant care in the city of Natal / RN, including a total of 222 women, 92 pregnant and 130 nonpregnant. The participants answered a questionnaire to obtain data and socio-demographic characteristics, as well as potential risk factors for sexually transmitted diseases. After the interview, we collected two cervical specimens, one for the Pap test and the other for DNA extraction and analyzed by polymerase chain reaction (PCR) to detect both virus serotypes. Then the women underwent a clinical examination by colposcopy. For statistical analysis, we used the chi-square and logistic regression by SSPS 17.0 Statistic. Most women were up to 30 years of age, nonwhite ethnicity, married, elementary education, family income below the poverty level; initiated sexual activity with age up to 18 years; had more than one sexual partner lifelong and was not pregnant, but has had at least one child. The HSV-1 showed a prevalence of 26.1% among pregnant women and 30.0% in non-pregnant women. While HSV-2 prevalence was found with 10.9% and 19.2% in pregnant and nonpregnant women, respectively. The largest proportion of morphological changes of the uterine cervix was detected among nonpregnant women, both in cytology and in colposcopy. The women were nonwhite ethnicity, married, became pregnant aged less than or equal to 18 years and who had one to two pregnancies had a lower risk of acquiring genital HSV infection. There was a high prevalence of genital HSV infection, HSV-1 is more prevalent than HSV-2. No association was found between morphological changes of the uterine cervix and the presence of the virus in pregnant and nonpregnant women, nor between genital HSV infection and the classic risk factors for sexually transmitted diseases

Metacromasia para identificação de basófilos sanguíneos em surubim híbrido: contribuição metodológica

Padua S.B. & Ishikawa M.M. [Metachromasia for blood basophils identification in hybrid surubim catfish: methodological contribution]. Metacromasia para identificacao de basofilos sanguineos em surubim hibrido: contribuicao metodologica. Revista Brasileira de Medicina Veterinaria, 33(3):147-150, 2011. Centro de Aquicultura da Unesp/Jaboticabal Rod. Paulo Donato Castellane, s/n Bairro Rural, Jaboticabal, 14884-900, SP. Brasil. E-mail: santiagopadua@live.comDifferent protocols of fixation and hydrolysis of blood smears of hybrid surubim catfish for metachromasia to marking blood basophils were evaluated. For this reason, methanol, acid-alcohol and formalin vapor were tested as fixatives. For hydrolysis of blood smears, HCl, citric acid and 2-Mercaptoethanol + Urea + NaCl solutions was evaluated. After procedures, the blood smears was stained with toluidine blue (0.025%) diluted in McIlvaine buffer (pH 4). The different protocols for fixation and hydrolysis of blood smears for metachromasia influenced the quality of the reaction. Hydrolysis with 2-Mercaptoethanol + Urea + NaCl solutions provided negative results when using methanol and acid-alcohol as fixatives. The fixation with acid-alcohol associated with citric acid hydrolysis provides highest quality reason.

Identificação morfológica de organismos semelhantes à anaplasmataceae em monócitos de surubim híbrido (Pseudoplatystoma reticulatum x P. corruscans) – relato de caso

The aim of this study was to report the occurrence of Anaplasmataceae-like organisms in monocytes from the hybrid surubim catfish. During the hematological evaluation of fish infected by Pseudomonas sp. in a fish farm located in the State of Mato Grosso do Sul we observed into the monocytes the presence of numerous pleomorphic inclusions of various sizes, rough in appearance which presented basophilic staining. These inclusions were similar to elementary bodies, initial bodies and morule of the bacteria from Anaplasmataceae family, often diagnosed in domestic mammals. This is the first report of its occurrence possibly belonging to the family of Anaplasmataceae in cultured fish in Brazil. Additional studies are necessary for molecular characterization of this bacteria, pathogenic potential, life cycle and impact on the intensive production of fish.
