Facing critical situations such as the ones triggered by COVID-19 may take healthcare professionals to confront their psychological resources, which may induce a higher stress level. We aimed to understand the feelings experienced by nurses, physiotherapists, and medical doctors in a field hospital dedicated to patients with COVID-19 in the biggest city of Brazil. Methods: We performed a qualitative study in a state field hospital in S?o Paulo city, Brazil, in a sample of 25 volunteer healthcare professionals. Participants answered to a sociodemographic electronic survey and were subjected to an individual semi-structured on-site interview. Results: Participants were mostly female (68%), comprised eight nurses, eight physiotherapists, and nine medical doctors, had an average age of 36.8 years, and were professionally experienced. Speech analysis revealed two thematic categories (related to work and assistance in the pandemic) and 11 subcategories: adaptation to the scenario, stressing experience, psychological support, difficulties with workwear, safety with workwear, non-verbal communication, empathy, patient comfort, outstanding experiences, major challenges, and teamwork. Conclusion: Nurses, physiotherapists, and medical doctors’ experiences while working in the field hospital were permeated by both positive and negative feelings. Those feelings originated directly from the fear of the unknown when dealing with a new disease without well-established scientific evidence, the use of medical workwear for long periods, and communication and environmental difficulties. In contrast, positive feelings, related to teamwork and empathy, arose and overlapped with the difficulties.

Restrictive measures adopted worldwide against COVID19(e.g.,wearing masks,frequent hand washing,and social distancing)produced not only a decrease in SARS-CoV-2 difusion but also a drastic reduction in respiratory diseases caused by other pathogens,as reported by many authors[1,2].The spread of respiratory viruses,particularly respiratory syncytial virus(RSV),has been completely changed during the winter of 2020–2021[3,4],but an unusual resurgence of RSV infection has been recently reported in diferent countries[3-7].

New Technique to Produce Large Amount of Flat Silk by Biospinning

引用

Agricultural Sciences 2014年第14期5卷 1483-1490页

Beyond the production of silk thread, there are several studies showing that the silk is a great biomaterial for surgical sutures and grafts. This paper shows a new technique to produce silk thread changing the natural cycle of silk production, which is the production of cocoons. This new method has the purpose of producing a silk fabric free of impurities, through flat surfaces. Six different surfaces were tested: Glass, Formica Surface, Steel and Zinc Sheets, Cotton tissue and Burlap Bag. The first five surfaces had not presented enough larvae alive for statistical analysis, because there were several damages in silkworms larvae that resulted in mortality and low silk production. On the other hand, the burlap bag surface presented good results for web construction by biospinning and its use was indicated for silk industry focused on biomaterials. The present study suggested the potential of naturally biospun web, using Bombyx mori, to develop a new technique to produce silk thread matrices that will have several applications at the industry and production of biomedical materials.

Renal Function after Major Uro-Oncologic Surgery and Dexmedetomidine Infusion

引用

Open Journal of Anesthesiology 2013年第8期3卷 356-362页

作者： Marcus Vinicius M. Novaes Paulo Sergio G. Lavinas Grace Haber D. Pires Ana claudia G. de Carvalho Renata M. B. Lopes regina El Dib Paulo do Nascimento Jr. Cancer Institute (INCA) Rio de Janeiro Brazil Department of Anesthesiology Univ Estadual Paulista (UNESP) Botucatu Brazil

Objective: Acute kidney injury in major surgery is associated with increased postoperative mortality. This study aimed to evaluate renal function after major urologic surgery and intraoperative dexmedetomidine infusion. Methods: Thirty oncologic patients with normal renal function scheduled for prostatectomy or nephrectomy, anesthetized with combined epidural and general anesthesia, were randomized to receive either intraoperative blind infusion of dexmedetomidine (Dexmedetomidine Group, n = 15, 0.5 μg/kg load dose plus 0.7 μg/kg/h) or 0.9% saline (Control Group, n = 15) until the end of surgery. Intraoperative and cumulative 24-hour diuresis, serum creatinine (SCr), calculated creatinine clearance (ClCr) and serum cystatin C (SCys) at postoperative days 1, 2 and 3 and 2 weeks after surgery were evaluated. Results: Mean ± standard deviation values for intraoperative diuresis in Dexmedetomidine and Control Groups were 566 ± 396 mL and 298 ± 153 mL, respectively (p = 0.014). Cumulative 24-hour diuresis in Dexmedetomidine and Control Groups was 1947 ± 266 mL and 1748 ± 237 mL, respectively (p = 0.91). Mean values of SCr, ClCr and SCys were not significantly different from their baseline values in both groups and no significant differences were seen between groups at any moment for two weeks (p > 0.05). Conclusion: According to the doses used in this study, despite an intraoperative increase in diuresis, intraoperative infusion of dexmedetomidine did not influence renal performance up to two weeks after major uro-oncologic surgery, as evaluated by SCr, ClCr and SCys.

Low Genetic Polymorphism at the Cytochrome C Oxidase I in Silkworm Strains of the Brazilian Germplasm Bank

引用

Open Journal of Genetics 2014年第3期4卷 202-209页

Nucleotide sequences have been used to distinguish species and specimens for many years. More recently, the use of a partial sequence of 650 bp of the cytochrome c oxidase I, COI mitochondrial gene, has been proposed for species identification, known as DNA barcodes. In this work, a short sequence of the DNA barcode is described—approximately 250 bp, named as “DNA mini-barcode”—to molecularly identify different silkworm strains maintained at the unique public Germplasm Bank of Bombyx mori, at the Universidade Estadual de Maringá, UEM, Brazil. Analysis revealed no significant differences among the silkworm strains. The phylogenetic tree obtained by the neighbor-joining method and K2P distance, in which specimens of B. mandarina were used as outgroup, clustered all the specimens of B. mori in a unique clade. Genetic variability detect within B. mori was low or nonexistent. In conclusion, the partial region of 250 bp of the mitochondrial gene COI herein analyzed may not be efficient to discriminate silkworm strains from the UEM Germplasm Bank of Bombyx mori.

This study reports the molecular detection of Bombyx mori nucleopolyhedrovirus (BmNPV) in silkworm strains of the Universidade Estadual de Maringá Brazilian Germplasm Bank (UBGB). DNA extraction was carried out by using six Bombyx mori female moths of each strain, followed by PCR amplification. A pair of primers was designed based on a specific sequence of the baculovirus genome related to the BmNPV ORF 14. Another pair of primers was used to amplify the silkworm Actin A3 gene segment, which was used as positive control. Twenty gene pools were analyzed, and fifteen revealed a fragment of 443 base pairs (bp), which indicated the presence of the BmNPV. The frequency of contaminated moths was as following: 100% for silkworm strains M18-2, M12-2 and J1;83% for C25, C75 and C24 strains;66% for KR01;50% for M11-A;33% for AS3, B106, M8 and M11 and 16% for C211, E8 and Hindu strains. These are promising results for the identification of contaminated B. mori moths by BmNPV, which may prevent virus proliferation in subsequent generations. We also analyzed DNA samples extracted from B. mori eggs, but the results were not conclusive regarding the detection of the fragments of the expected size (443 bp). The difficulty in detecting BmNPV contamination in B. mori eggs may be due to the low concentration of virus in samples.
