Investigation of anti-inflammatory and antinociceptive activities of trans-dehydrocrotonin, a 19-nor-clerodane diterpene from Croton cajucara .1.

The anti-inflammatory and antinociceptive effects of trans-dehydrocrotonin, isolated from the bark of Croton cajucara (Euphorbiaceae), were investigated using several animal models. The trans-dehydrocrotonin produced a significant inhibition of carrageenin-induced paw edema and cotton pellet granuloma in rats. It also inhibited the writhings in mice induced by acetic acid, but did not show a significant effect in the hot-plate test in mice. The LD(50) of t-DCTN was 555.0 mg/kg (p.o.) for mice

Self-care competence in the administration of insulin in older people aged 70 or over

ABSTRACT Objective: to analyze the self-care competence in the administration of insulin performed by older people aged 70 or over. Method: cross-sectional study carried out with 148 older people aged 70 or over, who performed self-administration of insulin. Data collection was carried out using a structured questionnaire and an adapted guide for the application of the Scale to Identify Self-Care Competence of Patients with Diabetes, at the participants’ home. Data analysis included descriptive and inferential statistical tests, with forward logistic regression. Results: the prevalence of self-care competence in the administration of insulin was 35.1%. Handwashing error was the most frequent in self-administration of insulin. Self-care competence was negatively associated with retirees and positively associated with senior patients who performed capillary blood glucose monitoring and skin pinching during insulin application. Conclusion: there was low self-care competence and it was associated with both the sociodemographic and the clinical characteristics with regard to self-application of insulin by the older people

These animals are considered natural reservoirs of different viruses that cause important diseases, being relevant research of viral pathogens in migratory birds to epidemiology surveillance. The objective of the study was to investigate the presence of avian rotavirus (AvRV), avian reovirus (ARV) and picobirnavirus (PBV) in Neotropical migratory birds captured on the coast of Brazil. A total of 23 individual fecal samples of the migratory birds species Calidris pusilla (20 birds), Numenius phaeopus (1 bird) and Charadrius semipalmatus (2 birds) were collected. Fecal suspensions were prepared from the collected samples for subsequent extraction of double-stranded RNA (dsRNA), which was subjected to polyacrylamide gel electrophoresis (PAGE) and reverse transcription polymerase chain reaction (RT-PCR). The electrophoretic profiles were not detected by PAGE, and the amplification for the studied viruses PBV, ARV and AvRV (specie D, gene VP6 and NSP4) were negative. Positivity for AvRVD, VP7 gene was of 4.35% (1/23) for the migratory bird Calidris pusilla. After sequencing and building the tree of phylogenetic relationships avian Rotavirus Group D identified in this study was phylogenetically related and grouped into one branch, together to previously reported AvRVD from Brazil in chicken flocks with 99.8% nucleotide and 100% amino acid similarities.Laboratório de Zoonoses Faculdade de Medicina Veterinária Universidade Federal do Pará, Campus Castanhal, Rodovia BR-316 Km 62 s/n, SaudadeInstituto Evandro Chagas (IEC), BR-316 Km 7 s/n, Distrito de LevilândiaLaboratório Nacional de Agricultura (Lana-gro/PA) Ministério da Agricultura Pecuária e Abastecimento (MAPA), Av.

Práticas baseadas em evidências publicadas no Brasil: identificação e análise de suas vertentes e abordagens metodológicas

Revisão integrativa de estudos brasileiros sobre práticas baseadas em evidências (PBE) em saúde, publicados em periódicos ISI/JCR, nos últimos 10 anos. O objetivo foi identificar as especialidades que mais realizaram estes estudos, seus enfoques e abordagens metodológicas. A partir de critérios de inclusão, foram selecionados 144 trabalhos. Os resultados indicam que a maior quantidade de estudos feitos em PBE foram sobre infância e adolescência, infectologia, psiquiatria/saúde mental e cirurgia. Os enfoques predominantes foram prevenção, tratamento/reabilitação, diagnóstico e avaliação. As metodologias mais empregadas foram revisão sistemática sem ou com metanálise, revisão de protocolos ou síntese de estudos de evidências já disponíveis, e revisão integrativa. Constata-se forte expansão multiprofissional da PBE no Brasil, contribuindo para a busca de práticas mais criteriosas pela reunião, reconhecimento e análise crítica dos conhecimentos produzidos. O estudo contribui também para a própria análise dos modos de fazer pesquisa e novas possibilidades de investigação
