RESUMEN

RESUMO Objetivo: construir e validar um instrumento para monitorar a qualidade dos registros de enfermagem no Programa de Assistência Domiciliar (PAD) em um hospital universitário. Método: estudo metodológico envolvendo a elaboração de um manual e submetido à validação de conteúdo por seis juízes sob consenso ≥ 80%. A coleta ocorreu em 2012 por meio de questionário contendo: evolução de enfermagem, diagnóstico e prescrição de enfermagem e normas para os registros da equipe de enfermagem preconizadas pelo Conselho Regional de Enfermagem-SP e pela instituição. Os itens do manual foram julgados de acordo com as variáveis - relevância, pertinência, clareza e simplicidade. Resultados: das 39 proposições 100% atingiram consenso ≥ 80% em relevância, pertinência e clareza; 92,3% em simplicidade. Os itens sono/repouso, mobilidade e checagem nas atividades prescritas não atingiram consenso mínimo favorável, sendo aprimorados pelas sugestões dos juízes. Conclusão: acreditamos que o instrumento possibilitará a melhoria dos processos de trabalho no PAD. .

ABSTRACT Objective: to build and validate an instrument aimed at monitoring the quality of nursing records in the Home Care Program (HCP) of a university hospital. Method: methodological study involving the elaboration of a manual, whose content was later submitted to six experts for validation, reaching a ≥ 80% consensus. The data collection process was carried out in 2012 by means of a questionnaire comprised of the following issues: nursing evolution, nursing diagnosis, and nursing prescription, and standards for the nursing team recommended by the Regional Nursing Council of São Paulo and by the assessed institution. Manual items were judged according to the following variables: relevance, pertinence, clarity and simplicity. Results: of the 39 propositions, 100% achieved ≥ 80% agreement in the relevance, pertinence and clarity variables; 92.3% in the simplicity variable. Sleep/rest, Mobility and Check-out variables did not reach a favorable minimum consensus in the prescribed activities and were improved following suggestions from the experts. Conclusion: we believe that the instrument will enable the improvement of the HCP’s work process. .

RESUMEN

Protein phosphatase magnesium/manganese-dependent 1D (PPM1D) is a p53-induced phosphatase that functions as a negative regulator of stress response pathways and has oncogenic properties. However, the functional role of PPM1D in bladder cancer (BC) remains largely unknown. In the present study, lentivirus vectors carrying small hairpin RNA (shRNA) targeting PPM1D were used to explore the effects of PPM1D knockdown on BC cell proliferation and tumorigenesis. shRNA-mediated knockdown of PPM1D significantly inhibited cell growth and colony forming ability in the BC cell lines 5637 and T24. Flow cytometric analysis showed that PPM1D silencing increased the proportion of cells in the G0/G1 phase. Downregulation of PPM1D also inhibited 5637 cell tumorigenicity in nude mice. The results of the present study suggest that PPM1D plays a potentially important role in BC tumorigenicity, and lentivirus-mediated delivery of shRNA against PPM1D might be a promising therapeutic strategy for the treatment of BC.

RESUMEN

Introdução: A doença renal crônica (DRC) e o tabagismo são problemas de saúde pública. Objetivo: Analisar o tabagismo como fator risco para a progressão da DRC. Métodos: Realizou-se uma revisão sistemática nas bases Medline, LILACS, SciELO, Google Acadêmico, Trials.gov e Embase com artigos publicados até fevereiro de 2013. Incluíram-se estudos: tipo coorte, ensaios clínicos e caso-controle. Realizados em seres humanos com idade ≥ 18 anos tendo tabagismo como fator de risco para progressão da DRC. Excluíram-se estudos que não referiam tabagismo e DRC no título ou tinham proposta de combate ao fumo. Resultados: Das 94 citações, 12 artigos foram selecionados. Destes, seis eram multicêntricos realizados em países desenvolvidos e quatro foram aleatorizados. Predominou o sexo masculino 51%-76%. Houve progressão associada ao tabagismo em 11 estudos. Identificou-se que o consumo ≥ 15 maços/ ano aumenta o risco de progressão da DRC. Conclusão: Tabagismo é fator de risco para progressão da DRC. .


Introduction: Chronic kidney disease (CKD) and smoking are public health problems. Objective: To assess smoking as a risk factor for progression of CKD. Methods: We conducted a systematic review in Medline, LILACS, SciELO, Google Scholar, Embase and Trials.gov with articles published until February/2013. Were included: cohort, clinical trials and case-control. Performed in humans, aged ≥ 18 years with smoking as a risk factor for progression of CKD. We excluded studies that reported no smoking and CKD in the title or had proposed to reduce smoking. Results: Among 94 citations, 12 articles were selected. Of these, six were multicenter conducted in developed countries, four were randomized. Males predominated 51-76%. There was associated with smoking progression in 11 studies. It was found that the consumption ≥ 15 packs/ year increases the risk of progression of CKD. Conclusion: Smoking is a risk factor for progression of CKD. .

RESUMEN

The specific signaling connections between the mitogen-activated protein kinases (MAPK) such as c-Jun N-terminal kinase (JNK-1) and phosphatases PP4 and M3/6, affecting the family of early nuclear factors, is complex and remains poorly understood. JNK-1 regulates cellular differentiation, apoptosis and stress responsiveness by up-regulating early nuclear factors such as c-Jun, a member of the activating protein (AP-1) family, and the Early Growth Factor (EGR-1). C-Jun, when phosphorylated by c-Jun N-terminal kinase (JNK-1) associates with c-Fos to form the AP-1 transcription factor that activates gene expression. We have investigated the regulation of the JNK-1 kinase by co-transfecting phosphatases PP4 and M3/6 in prostate cancer cell lines PC-3 and LNCaP, which have been previously stimulated with human EGF or cisplatin. Co-transfections of plasmids expressing the JNK-1 and the serine/threonine phosphatases PP4 resulted in a significant increase in JNK-1 activity in both PC3 and LNCaP cells. In contrast, co-transfection of JNK-1 with the dual specific phosphatase serine/threonine M3/6 showed only a marginal effect in JNK-1 activity. The phosphatase M3/6 also failed in blocking the induction of JNK-1 activity observed in presence of PP4. The higher activity of JNK-1 was associated with increased activities of the factors c-Jun/AP-1 and EGR-1. This suggests that JNK-1 activity in PC-3 and LNCaP cells requires not only active PP4 for stable maintenance but also suggests that the relative degree of phosphorylation of multiple cellular components is the determinant of JNK-1 stability.

RESUMEN

CPTP1 is a nontransmembrane chicken protein tyrosine phosphatase having 92% sequence homology to the corresponding 321 amino acids of human protein tyrosine phosphatase 1B (HPTP1B). Using anti-CPTP1 antibody, we identified CPTP1-like rat PTP1 of 51 kappa Da in Rat-1 and v-src-transformed Rat-1 fibroblasts. Here we show that CPTP1-like rat PTP1 binds to p60v-src in vivo and CPTP1 also can associate with p60v-src in cell lysate of v-src- transformed Rat-1 fibroblasts. Interaction between HPTP1B-type PTPs, CPTP1-like rat PTP1 and CPTP1, and p60v-src was reduced by vanadate treatment for 13 h due to down regulation of the protein level of p60v-src in vivo. Interestingly, CPTP1-like rat PTP1 was coimmunoprecipitated with a 70-kappa Da protein which has a possibility to be tyrosine- phosphorylated by p60v-src in v-src-transformed Rat- 1 fibroblasts. These results suggest that HPTP1B- type PTPs may play an important role in p60src dependent signal pathway in eucaryotic cells.
