The first baseline of ALDFG generated by the artisanal fishery during the SARS-CoV-2 pandemic on the north coast of Pernambuco, Brazil.

To prevent the spread of the COVID-19 contagion, some regions of Brazil implemented a prohibition of beach use, which contributed to a reduction of artisanal fishing activity. This study aimed to evaluate the influence of these beach closures on the incidence of abandoned, lost, or discarded fishing gear (ALDFG) along four beaches located on the northern coast of Pernambuco, Brazil. The absolute and relative frequency of occurrence and the number of observations per unit of effort (OPUE) between the periods before and after the prohibition period were analyzed. A total of 1935 fishing gear residues were found (63% before and 37% after prohibition). There was also a significant reduction in OPUE and in absolute frequency (p < 0.05) between these two periods. Although beach closures appear to have contributed to a reduction in the amount of ALDFG in the region, it does not indicate a complete pause in fishing activities.

Laserterapia de baixa intensidade no tratamento de feridas e a atuação da enfermagem / Laser therapy low intensity in wound care and practice nurses

Objetivo: identificar os benefícios da laserterapia no tratamento de feridas e a atuação da enfermagem neste processo. Metodologia: revisão Integrativa da Literatura. A partir das questões >, a amostra foi composta por 12 (doze) artigos científicos. O levantamento bibliográfico foi realizado na Biblioteca Virtual de Saúde. Foram artigos publicados em português, inglês e espanhol, na íntegra nas bases de dados, no período entre 2008 a 2016. Resultados: são evidentes os benefícios da Terapia com Luz de Baixa Intensidade nas feridas, já na primeira sessão com a analgesia, anti-inflamatório e cicatrização. O profissional habilitado realiza a avaliação, desenvolve o plano de cuidados pautado no processo de enfermagem e exerce sua autonomia nesse tipo de tratamento. Conclusão: a literatura mostra os vários benefícios do uso da lasertarapia nas lesões cutâneas agindo de forma intrínseca e extrínseca e a enfermagem é uma profissão capaz de aplicar o recurso terapêutico, desde que obtenha qualificação adequada.

Objective: to identify the benefits of laser therapy in wounds treatment and the nursing role at this process.Methodology: integrative literature review. From the questions >, the sample was formed by 12(twelve) papers. The research was conducted at the Virtual Health Library and included papers published in Portuguese, English and Spanish with full text available at the databases, from 2008 to 2016. Results: the benefits of low-intensity laser at wounds treatments are evident, at the first session with the use of analgesic,anti-inflammatory and at the healing process. The registered nurse performs the evaluation, develops the care plan in accordance with the nursing process and has autonomy throughout the treatment. Conclusion:the literature shows the a variety of benefits of using laser therapy in skin lesions acting intrinsically and extrinsically; and nursing is a profession able of applying the therapeutic resource, as long as obtain proper qualification.

Evaluation of a generic RT-nested-PCR for detection of flaviviruses in suspected fatal cases of dengue infection, Rio de Janeiro, Brazil.

Flaviviruses are significant causes of disease worldwide and can be classified serologically into several antigenic complexes. The purpose of the present study was to evaluate the effectiveness of a generic RT-nested-PCR for detection of flavivirus during a dengue outbreak in Brazil in 2008. A total of 105 serum samples were collected from patients with fatal outcome and examined by generic RT-PCR, conventional RT-PCR, and IgM serology. The generic RT-PCR confirmed 19 of 105 (18%) cases. Conventional RT-PCR performed on 105 serum samples detected 45 (42.8%) dengue virus infections. The IgM serology confirmed 44 of 102 (43.1%) cases. The infecting serotype was identified by generic RT-PCR in 19 cases (18 DENV-2 and 1 DENV-3) and by conventional RT-PCR in 45 cases (40 DENV-2 and 5 DENV-3). In addition, we analyzed the performance of the generic and conventional RT-PCRs and IgM serology on serum samples stratified by the day of onset of symptoms. Our results indicate that different methods should be included in flavivirus surveillance programs, including virological and serological approaches.
