Cuidado de enfermagem ao paciente com comorbidade clínico-psiquiátrica em um pronto atendimento hospitalar

Pesquisa qualitativa, descritiva, exploratória desenvolvida em 2009 no pronto atendimento de um hospital geral de Curitiba, Paraná. Teve como objetivo conhecer o cuidado de enfermagem desenvolvido ao paciente com comorbidade clínico-psiquiátrica. Participaram seis enfermeiros, sete técnicos de enfermagem e 14 auxiliares de enfermagem. Os dados foram obtidos mediante entrevista semiestruturada e submetidos à análise de conteúdo temático-categorial. As categorias que emergiram dos dados foram: O cuidado é técnico e sem especificidade; Segurança e proteção ao paciente; e Contenção física e química como medidas de proteção. Evidenciouse que os cuidados de enfermagem desenvolvidos aos pacientes com comorbidade clínico-psiquiátrica são sem especificidade, com ênfase em cuidados básicos, contenção química e física. Concluiu-se que há necessidade da implantação de programas locais de capacitação em saúde mental e sensibilização dos profissionais de enfermagem quanto aos cuidados a tal clientela

Mucosal Leishmaniasis Caused by Leishmania (Viannia) braziliensis and Leishmania (Viannia) guyanensis in the Brazilian Amazon

Background: Leishmania (Viannia) braziliensis is a parasite recognized as the most important etiologic agent of mucosal leishmaniasis (ML) in the New World. In Amazonia, seven different species of Leishmania, etiologic agents of human Cutaneous Leishmaniasis, have been described. Isolated cases of ML have been described for several different species of Leishmania: L. (V.) panamensis, L. (V.) guyanensis and L. (L.) amazonensis. Methodology: Leishmania species were characterized by polymerase chain reaction (PCR) of tissues taken from mucosal biopsies of Amazonian patients who were diagnosed with ML and treated at the Tropical Medicine Foundation of Amazonas (FMTAM) in Manaus, Amazonas state, Brazil. Samples were obtained retrospectively from the pathology laboratory and prospectively from patients attending the aforementioned tertiary care unit. Results: This study reports 46 cases of ML along with their geographical origin, 30 cases caused by L. (V.) braziliensis and 16 cases by L. (V.) guyanensis. This is the first record of ML cases in 16 different municipalities in the state of Amazonas and of simultaneous detection of both species in 4 municipalities of this state. It is also the first record of ML caused by L. (V.) guyanensis in the states of Para, Acre, and Rondonia and cases of ML caused by L. (V.) braziliensis in the state of Rondonia. Conclusions/Significance: L. (V.) braziliensis is the predominant species that causes ML in the Amazon region. However, contrary to previous studies, L. (V.) guyanensis is also a significant causative agent of ML within the region. The clinical and epidemiological expression of ML in the Manaus region is similar to the rest of the country, although the majority of ML cases are found south of the Amazon River.SUFRAMA[016/2004

Actions of a Proline Analogue, L-Thiazolidine-4-Carboxylic Acid (T4C), on Trypanosoma cruzi

It is well established that L-proline has several roles in the biology of trypanosomatids. In Trypanosoma cruzi, the etiological agent of Chagas' disease, this amino acid is involved in energy metabolism, differentiation processes and resistance to osmotic stress. In this study, we analyzed the effects of interfering with L-proline metabolism on the viability and on other aspects of the T. cruzi life cycle using the proline analogue L- thiazolidine-4-carboxylic acid (T4C). The growth of epimastigotes was evaluated using different concentrations of T4C in standard culture conditions and at high temperature or acidic pH. We also evaluated possible interactions of this analogue with stress conditions such as those produced by nutrient starvation and oxidative stress. T4C showed a dose-response effect on epimastigote growth (IC50 = 0.89±0.02 mM at 28°C), and the inhibitory effect of this analogue was synergistic (p<0.05) with temperature (0.54±0.01 mM at 37°C). T4C significantly diminished parasite survival (p<0.05) in combination with nutrient starvation and oxidative stress conditions. Pre-incubation of the parasites with L-proline resulted in a protective effect against oxidative stress, but this was not seen in the presence of the drug. Finally, the trypomastigote bursting from infected mammalian cells was evaluated and found to be inhibited by up to 56% when cells were treated with non-toxic concentrations of T4C (between 1 and 10 mM). All these data together suggest that T4C could be an interesting therapeutic drug if combined with others that affect, for example, oxidative stress. The data also support the participation of proline metabolism in the resistance to oxidative stress

Care needs and workload required by institutionalised psychiatric patients

OBJECTIVES: This descriptive study used a quantitative approach to assess the nursing care needs of patients with mental disorders, the mean number of care hours these patients were provided and the workload these patients require nursing team. METHODS: The research was conducted in a public neuropsychiatric hospital located in south eastern Brazil in 2010 and included 105 patients as subjects. A patient classification tool was applied to characterise care profiles. Statistical analysis was performed using principal component analysis and analysis of variance. RESULTS: Patients were predominantly in the low care category (73.3%). The mean care hours ranged from 0.57 to 0.88 for nurses and 1.97 to 3.16 for nursing assistants, and the workload ranged from 119.6 to 183 hours . CONCLUSIONS: The present study showed that the care needs of most patients were at a low level of dependency and that most patients did not need to be institutionalised. Furthermore, it was found that the care hours provided by the nursing staff were not sufficient to meet the care needs of the patients
