Saúde Mental e enfermagem: em busca da integralidade na ESF

The present work shows an inquiry about the conceptions and practical work of the nursing professionals on the accompaniment of mental sick patients in the Family s Health Strategy, under the approach of the completeness in health. The justification of this research is given by bringing an special attention concerning the subjet to these professionals of health: the gradual abandonment of the traditional manicomial model leads to the insertion of mental patients in the community . The nursing professionals must be prepared to receive these patients in the basic net of health and contribute to help their adaptation and insertion in the social environment as citizen. In this context, considering the entire attention to the mental health, it is important to detach that the assistance to the patient must search his reinsertion in the community by providing programs that develops his sociability. This analytical study was developed using a qualitative approach and a thematic verbal history. Ten nurses of Nova Natal s Health of the Family Unit, of Felipe Camarão Mista s Unit and of Cidade da Esperança s Health Unit contributed for its development . The information was acquired through an instrument research that made possible the accomplishment of the interviews. These ones were set previously and counted on the assent of the participants. The interviews were recorded and analyzed in accordance with the pertinent literature concerning the subject. The aggregation of the information was then discussed. At this moment three thematic axles were defined dividing the categories of analysis. According to the results of the interviews, the practical procedure given to the patients with mental upheaval is resumed by the prescription of psicotroprics medicaments. It doesn t provide an accompaniment by the professionals of health, specifically, nurses, to the patients and their families. The lack of qualification and a multi-professional team emerged as one of the challenges for the implementation of practical procedures towards the patients with mental upheaval. Therefore, the results of this research show the necessity of transformations in the current scene of the mental health in the Family s Health Strategy. These changes can be reached by politics investments on the mental health area, not only financially but by providing human resources that should allow the professionals to exert the completeness procedures

Evaluation and development of passion fruit (Passiflora alata Dryander) propagated by cutting and seet in conditions of commercial orchard

The present work was conducted in a fruit tree propagation area of the Plant Production Department of the Faculdade de Ciencias Agrarias e Veterinarias, Universidade Estadual Paulista (FCAV/UNESP) in Jaboticabal, SP, and also in a commercial orchard in Araguari, MG, with the objective to verify the potential of vegetative growth (stem diameter, height of plants and leaf number) of plants of passion fruit (Passiflora alata Dryander), gotten by cutting and seed, comparing the initial development of plants in the field. This experiment was carried out from January 2002 to February 2003. The experiment using seeds was conducted at a shadow house, and the one that used cuttings in an intermitent mist. The cuttings and seeds were collected from adult plants which came from Passifloraceae Active Germoplasm Bank (BAG) of the Plant Production Department of FCAC/UNESP. For the cuttings, it was used the intermediate part of the branches in stadium of vegetative growth. The seeds, in order to obtain the seedlings, had been sown in plastic trays. Cuttings and seedlings were transplanted to plastic bags with substrate in shadow house and with daily irrigation. They were acclimatized and planted on field, after 60 days. on field, the stem diameter, plant height and number of leaves were better for cuttings than for seedlings in Jaboticabal, SP. In Araguari, MG, stem diameter was larger in the seedlings, which plant heights and number of leaves were larger on cuttings.

A atenção em Saúde Mental em municípios de pequeno e médio portes: ressonâncias da reforma psiquiátrica

A partir da análise da Política Nacional de Saúde Mental formulada nos últimos anos e das experiências desenvolvidas após 1987 no país, procura-se compreender como o Sistema Único de Saúde tem contribuído ao avanço da reforma psiquiátrica nos municípios; verificar como a assistência oferecida nesses municípios está viabilizando os princípios da reforma psiquiátrica e a melhora das condições de vida dos usuários, bem como pesquisar o papel dos trabalhadores e gestores na construção de novas práticas de cuidado em Saúde Mental. A análise das práticas discursivas aponta que os vários segmentos sociais envolvidos na Saúde Mental conhecem os princípios e propostas da reforma psiquiátrica. No entanto, as gestões municipais não assumem integralmente as propostas do Ministério da Saúde para a área, sob a alegação de falta de recursos financeiros para a contrapartida exigida. Os usuários e familiares têm aos poucos assumido as novas propostas de intervenção, mas os mecanismos de participação e organização popular ainda são incipientes. Por fim, deve-se destacar que, para uma efetiva consolidação das propostas atuais da reforma psiquiátrica, é necessário um maior compromisso dos gestores com a atenção em Saúde Mental, maior investimento nas equipes multiprofissionais, o estímulo à organização e à participação dos usuários e familiares e a integralidade dos dispositivos de saúde, de assistência social e de cultura existentes nas cidades.

Differential behavioral and neuroendocrine effects of repeated nicotine in adolescent and adult rats

Despite the high prevalence of tobacco abuse among adolescents, the neurobiology of nicotine addiction has been studied mainly in adult animals. Repeated administration of this drug to adult rats induces behavioral sensitization. Nicotine activates the HPA axis in adult rats as measured by drug-induced increases in ACTH and corticosterone. Both behavioral sensitization and corticosterone are implicated in drug addiction. We examined the expression of behavioral sensitization induced by nicotine as well as the changes in corticosterone levels after repeated injections of nicotine in adolescent and adult animals. Adolescent and adult rats received subcutaneous (s.c.) injections of saline or 0.4 mg/kg of nicotine once daily for 7 days. Three days after the last injection animals were challenged with saline or nicotine (0.4 mg/kg; s.c.). Nicotine-induced locomotion was recorded in an activity cage. Trunk blood samples were collected in a subset of adolescent and adult rats and plasma corticosterone levels were determined by radioimmunoassay. Adult, but not adolescent, rats expressed behavioral sensitization. Pretreatment with nicotine abolished corticosterone-activating effect of this drug only in adult animals, indicating the development of tolerance at this age. Our results provide evidence that adolescent rats exposed to repeated nicotine display behavioral and neuroendocrine adaptations distinct from that observed in adult animals. (c) 2004 Elsevier B.V.

Empresa social e economia solidária: perspectivas no campo da inserção laboral de portadores de transtorno mental

O processo da reforma psiquiátrica requer a implementação de políticas públicas que garantam a inserção laboral de portadores de transtorno mental. Para tal, é necessário que o trabalho seja compreendido como promotor de autonomia, de emancipação e de cidadania. O objetivo deste estudo é refletir acerca de concepções teóricas relacionadas à inserção social pelo trabalho, a fim de explorar o campo da inclusão de portadores de transtorno mental no mundo do trabalho. Foram escolhidos os conceitos de empresa social e de economia solidária como fundamentais para o estudo. Na empresa social, o sujeito é entendido como ser social, enfocando-se seu processo de formação no sentido da emancipação. Na economia solidária, objetiva-se o desenvolvimento de uma forma de economia mais justa que tem como característica a igualdade e a solidariedade. Sugerimos que a discussão desses conceitos possa contribuir para embasar a implantação de projetos de inclusão social pelo trabalho.

Neonatally-induced diabetes: lipid profile outcomes and oxidative stress status in adult rats

INTRODUÇÃO: Modelos experimentais são desenvolvidos com propósito de ampliar o entendimento dos mecanismos fisiopatológicos envolvidos no diabete. Os achados experimentais levam ao desenvolvimento de tratamentos alternativos para a manutenção das condições metabólicas normais. Existem vários estudos sobre o diabete induzido por streptozotocin mimetizando o quadro clínico do DM2. No entanto, a interação entre os níveis de glicose, perfil lipídico e estresse oxidativo nestes animais são escassos. Portanto, o objetivo do trabalho foi avaliar estes parâmetros em ratas Wistar adultas com diabete induzido com streptozotocin no período neonatal. MÉTODOS: Fêmeas recém-nascidas receberam streptozotocin (70mg/Kg, ip) no 5º dia de vida (n5-STZ). A glicemia foi medida no terceiro e quarto meses de vida dos animais. No final do quarto mês de vida, amostras de sangue foram coletadas e processadas para a dosagem de lipídios e marcadores de estresse oxidativo. RESULTADOS: A glicemia das ratas do grupo n5-STZ foi significativamente maior comparada às ratas do grupo controle (p<0,05). Não houve alteração nos níveis de colesterol total e triglicérides, peroxidação lipídica (TBARS), atividade da SOD e determinação da GSH-t (p>0,05) nas ratas n5-STZ em relação às ratas do grupo controle. No entanto, houve diminuição significativa no HDL-colesterol (p<0,05). CONCLUSÃO: Este modelo de indução de diabete em ratas causou hiperglicemia (120-360mg/dL), caracterizando o diabete moderado. Essa glicemia levou a alterações no HDL-colesterol, a qual não foi suficiente para prejudicar a atividade das enzimas antioxidantes ou marcadores da peroxidação lipídica na vida adulta. Além disso, esta investigação experimental contribuiu para entender os diferentes resultados encontrados em outros modelos deindução do diabete moderado em animais de laboratório, como também para a melhor compreensão dos mecanismos fisiopatológicos do diabete moderado ou da hiperglicemia em humanos.

Agaricus blazei (Himematsutake) does not alter the development of rat diethylnitrosamine-initiated hepatic preneoplastic foci

The modifying potential of crude extracts of the mushroom Agaricus blazei Murrill (Himematsutake) on the development and growth of glutathione S-transferase placental form (GST-P)-positive liver foci (liver preneoplastic lesion) was investigated in adult male Wistar rats. Six groups of animals were used. Groups 2 to 5 were given a single i.p. injection of 200 mg/kg b.w. of diethylnitrosamine (DEN) and groups 1 and 6 were treated with saline at the beginning of the experiment. After 2 weeks, animals of groups 3 to 6 were orally treated with three dose levels of aqueous extracts of the mushroom A. blazei (1.2, 5.6, 11.5, and 11.5 mg/ml of dry weight of solids) for 6 weeks. All animals were subjected to two-thirds partial hepatectomy at week 3 and sacrificed at week 8. Two hours before sacrifice, ten animals of each group were administered a single i.p injection of 100 mg/kg of bromodeoxyuridine (BrdU). Apoptotic bodies and BrdU-positive hepatocyte nuclei were quantified in liver sections stained for hematoxylin and eosin (H&E) (eosinophilic foci) and simultaneously stained for GST-P expression (GST-P-positive foci), respectively. The 6-week treatment with A. blazei did not alter the development (number and size) of GST-P-positive foci and did not affect the growth kinetics of liver normal parenchyma or foci in DEN-initiated animals. Our results indicate that the treatment with aqueous extracts of the mushroom A. blazei during the post-initiation stage of rat liver carcinogenesis does not exert any protective effect against the development of GST-P-positive foci induced by DEN.

Characterization of S3Pvac Anti-Cysticercosis Vaccine Components: Implications for the Development of an Anti-Cestodiasis Vaccine

Background: Cysticercosis and hydatidosis seriously affect human health and are responsible for considerable economic loss in animal husbandry in non-developed and developed countries. S3Pvac and EG95 are the only field trial-tested vaccine candidates against cysticercosis and hydatidosis, respectively. S3Pvac is composed of three peptides (KETc1, GK1 and KETc12), originally identified in a Taenia crassiceps cDNA library. S3Pvac synthetically and recombinantly expressed is effective against experimentally and naturally acquired cysticercosis.Methodology/ Principal Findings: In this study, the homologous sequences of two of the S3Pvac peptides, GK1 and KETc1, were identified and further characterized in Taenia crassiceps WFU, Taenia solium, Taenia saginata, Echinococcus granulosus and Echinococcus multilocularis. Comparisons of the nucleotide and amino acid sequences coding for KETc1 and GK1 revealed significant homologies in these species. The predicted secondary structure of GK1 is almost identical between the species, while some differences were observed in the C terminal region of KETc1 according to 3D modeling. A KETc1 variant with a deletion of three C-terminal amino acids protected to the same extent against experimental murine cysticercosis as the entire peptide. on the contrary, immunization with the truncated GK1 failed to induce protection. Immunolocalization studies revealed the non stage-specificity of the two S3Pvac epitopes and their persistence in the larval tegument of all species and in Taenia adult tapeworms.Conclusions/ Significance: These results indicate that GK1 and KETc1 may be considered candidates to be included in the formulation of a multivalent and multistage vaccine against these cestodiases because of their enhancing effects on other available vaccine candidates.
