Effect of a gel containing pilocarpine on vaginal atrophy in castrated rats

OBJECTIVES: To evaluate the effect of Carbopol gel formulations containing pilocarpine on the morphology and morphometry of the vaginal epithelium of castrated rats. METHODS: Thirty-one female Wistar-Hannover rats were randomly divided into four groups: the control Groups I (n=7, rats in persistent estrus; positive controls) and II (n=7, castrated rats, negative controls) and the experimental Groups, III (n=8) and IV (n=9). Persistent estrus (Group I) was achieved with a subcutaneous injection of testosterone propionate on the second postnatal day. At 90 days postnatal, rats in Groups II, III and IV were castrated and treated vaginally for 14 days with Carbopol gel (vehicle alone) or Carbopol gel containing 5% and 15% pilocarpine, respectively. Next, all of the animals were euthanized and their vaginas were removed for histological evaluation. A non-parametric test with a weighted linear regression model was used for data analysis (

Seroprevalence of Chikungunya Virus after Its Emergence in Brazil.

Chikungunya has had a substantial impact on public health because of the magnitude of its epidemics and its highly debilitating symptoms. We estimated the seroprevalence, proportion of symptomatic cases, and proportion of chronic form of disease after introduction of chikungunya virus (CHIKV) in 2 cities in Brazil. We conducted the population-based study through household interviews and serologic surveys during October-December 2015. In Feira de Santana, we conducted a serologic survey of 385 persons; 57.1% were CHIKV-positive. Among them, 32.7% reported symptoms, and 68.1% contracted chronic chikungunya disease. A similar survey in Riachão do Jacuípe included 446 persons; 45.7% were CHIKV-positive, 41.2% reported symptoms, and 75.0% contracted the chronic form. Our data confirm intense CHIKV transmission during the continuing epidemic. Chronic pain developed in a high proportion of patients. We recommend training health professionals in management of chronic pain, which will improve the quality of life of chikungunya-affected persons

Aortic Response to Strength Training and Spirulina platensis Dependent on Nitric Oxide and Antioxidants

Studies have shown that supplementation with Spirulina platensis improves vascular reactivity. However, it is unclear whether in association with strength training this effect can be enhanced. Thus, this study aimed to determine the effects of strength training and S. platensis on the reactivity of the aorta from Wistar rat and the possible mechanisms involved. The animals were supplemented with S. platensis and divided into sedentary (SG, SG50, SG150, and SG500) and trained groups (TG, TG50, TG150, and TG500). Nitrite, malondialdehyde (MDA) and antioxidant activity were determined by biochemical assays. To evaluate vascular response, cumulative concentration—response curves to phenylephrine (PHE) and acetylcholine (ACh) were constructed. L-NAME was used to assess the participation of nitric oxide (NO). It was observed that the PHE contractile potency was reduced in TG50, TG150, and TG500 groups compared to SG50, SG150, and SG500 groups, respectively. However, the presence of L-NAME increased the contractile response in all groups. Strength training potentiated the increase in relaxing activity induced by S. platensis, where the pCE50 values of ACh increased in TG150 and TG500. These responses were accompanied by increased nitrite production, MDA reduction and increased antioxidant activity in the aorta of both TG150 and TG500 groups. Thus, the present study demonstrated that combined with strength training, S. platensis potentiates vascular improvement through the participation of NO and reduction of oxidative stress

Attitudes of nurses towards families: validation of the scale Families' Importance in Nursing Care - Nurses Attitudes

The attitudes of nurses towards families determine the care process. With this study, we aimed to obtain an instrument that would allow us to learn about this variable. Hence, our purpose was to perform the cross-cultural adaptation and evaluate the psychometric features of the Portuguese version of the instrument Families' Importance in Nursing Care - Nurses Attitudes (FINC-NA), which aims to evaluate the attitudes of nurses towards the importance of involving the patient's family in the nursing care. The method recommended by the literature was followed. The sample consisted of 136 nurses working in primary health care. The results obtained in the reliability tests showed good internal consistency (Cronbach's Alpha=0.87). The psychometric study permits us to state that the Portuguese version of the FINC-NA, which in Portuguese is referred to as A importância das famílias nos cuidados de enfermagem - atitudes dos enfermeiros (IFCE-AE), is a reliable and valid tool.As atitudes que os enfermeiros adotam em relação à família condicionam o processo de cuidar. Nosso propósito com este estudo foi nesse sentido: dispor de um instrumento que nos permitisse conhecer esta variável. Assim, nossa proposta foi efetuar a adaptação transcultural e avaliar as propriedades psicométricas da versão portuguesa do instrumento Families' Importance in Nursing Care - Nurses Attitudes (FINC-NA), que visa avaliar as atitudes dos enfermeiros acerca da importância de envolver a família nos cuidados de enfermagem. Foi seguido o método preconizado pela literatura. A amostra foi constituída por 136 enfermeiros dos Cuidados de Saúde Primários. Os resultados obtidos nos testes de confiabilidade revelam uma boa consistência interna para o total dos itens (Alpha de Cronbach = 0,87). O estudo psicométrico permite-nos afirmar que a versão em português da FINC-NA, que denominamos A importância das famílias nos cuidados de enfermagem - atitudes dos enfermeiros (IFCE-AE), é um instrumento fidedigno e válido.Las actitudes adoptadas por enfermeros en relación a la familia condicionan el proceso de cuidar.

Así, nos propusimos efectuar la adaptación transcultural y evaluar las propiedades psicométricas de la versión portuguesa del instrumento Families Importance in Nursing Care - Nurses Attitudes (FINC-NA), que apunta a evaluar actitudes de enfermeros acerca de involucrar a la familia en los cuidados de enfermería. Se siguió el método sugerido por la literatura. Muestra constituida por 136 Enfermeros de Atención Primaria de Salud. Los resultados obtenidos en pruebas de fiabilidad revelan buena consistencia interna para el total de ítems (Alpha de Cronbach=0,87). El estudio psicométrico nos permite afirmar que la versión en Portugués del FINC-NA, que denominamos La importancia de las familias en el cuidado de enfermería - actitudes de los enfermeros (IFCE-AE) es un instrumento fidedigno y válido

Inquérito com paracoccidioidina em uma população da Bahia (Brasil)

No Município de Una, localizado ao Sul do Estado da Bahia, em área com registro freqüente de casos de leishmaniose tegumentar, foram estudados 177 indivíduos, na faixa etária entre três meses e 73 anos, através de provas intradérmicas com paracoccidioidina (antígeno péptido-polissacarídico do Paracoccidioides brasiliensis). Positividade foi obtida em dez indivíduos (5,6%). Somente foi considerada positiva a reação que apresentava enduração igual ou maior que 5 mm. Em nenhum dos casos positivos à paracoccidioidina havia evidência clínica de lesões blastomicóticas. Com os soros dos indivíduos positivos à paracoccidioidina, foram realizadas provas de imunodifusão dupla e contraimunoeletroforese, com resultados negativos para anticorpos circulantes anti-P. brasiliensis. Este dado indica que, em nenhum dos reatores à paracoccidioidina, havia processo infeccioso em atividade. O percentual de positividade obtido com a paracoccidioidina, em que pesem eventuais reações cruzadas com histoplasmose, sugere a ocorrência da paracoccidioidomicose na área estudada
