Introduction: The perioperative nurse plays an important role throughout the surgical period, especially in the context of predicting the risks to which patients are exposed when entering a surgical center. These can be skin, muscle, tendon, and even burn injuries from the scalpel or chemicals. Objective: The aim of this study was to verify the degree of risk for the development of injuries resulting from surgical positioning in patients of a university hospital. Methods: This is cross-sectional, exploratory research with a quantitative approach conducted with 70 surgical patients in a Municipal University Hospital with data collection through a socioeconomic and health questionnaire and the Risk Assessment Scale for Development of Surgical Positioning Injuries (SISP). Statistical analyses included simple descriptive evaluation, correlations of variables using the Chi-square test and Pearson’s coefficient with a significance level of 5%. Results: The results found pointed to a population mainly composed of women (60%), married, with an average age of 49 years, with hypertension and high-risk scores to develop injuries due to surgical positioning. There was also a positive and significant correlation between having hypertension and having a higher risk of developing lesions, with R2 = 96.4% and p Conclusion: The results reinforce the need to implement protocols and the acquisition of materials aimed at reducing the risk of injuries related to surgical positioning in order to improve the quality of care offered and thus minimize the harm to users.

Microbiota modification by probiotic supplementation reduces colitis associated colon cancer in mice

World Journal of Gastroenterology 2018年第18期24卷 1995-2008页

作者： Maria carolina S mendes Daiane SM Paulino Sandra R Brambilla Juliana A Camargo Gabriela F Persinoti José Barreto C Carvalheira Department of Internal Medicine Faculty of Medical Sciences State University of Campinas (UNICAMP) Brazilian Bioethanol Science and Technology Laboratory (CTBE) Brazilian Center for Research in Energy and Materials (CNPEM)

AIM To investigate the effect of probiotic supplementation during the development of an experimental model of colitis associated colon cancer(CAC). METHODS C57 BL/6 mice received an intraperitoneal injection of azoxymethane(10 mg/kg), followed by three cycles of sodium dextran sulphate diluted in water(5% w/v). Probiotic group received daily a mixture of Lactobacillus acidophilus, Lactobacil us rhamnosus and Bifidobacterium bifidum. Microbiota composition was assessed by 16 Sr RNA Illumina Hi Seq sequencing. Colon samples were collected for histological analysis. Tumor cytokines was assessed by Real Time-PCR(Polymerase Chain Reaction); and serum cytokines by Multiplex assay. All tests were two-sided. The level of significance was set at P < 0.05. Graphs were generated and statistical analysis performed using the software Graph Pad Prism 5.0. The project was approved by the institutional review board committee. RESULTS At day 60 after azoxymethane injection, the mean number of tumours in the probiotic group was 40% lower than that in the control group, and the probiotic group exhibited tumours of smaller size(< 2 mm)(P < 0.05). There was no difference in richness and diversity between groups. However, there was a significant difference in beta diversity in the multidimensional scaling analysis. The abundance of the genera Lactobacillus, Bifidobacterium, Allobaculum, Clostridium XI and Clostridium XVⅢ increased in the probiotic group(P < 0.05). The microbial change was accompanied by reduced colitis, demonstrated by a 46% reduction in the colon inflammatory index; reduced expression of the serum chemokines RANTES and Eotaxin; decreased p-IKK and TNF-α and increased IL-10 expression in the colon. CONCLUSION Our results suggest a potential chemopreventive effect of probiotic on CAC. Probiotic supplementation changes microbiota structure and regulates the inflammatory response, reducing colitis and preventing CAC.

In a recent study published in Nature,Liu and co-workers show that high lactate production by tumor cells promotes premature mitotic escape and further cell proliferation by facilitating the binding of Ubiquitin Conjugating Enzyme E2 C(UBE2C)to the anaphase promoting complex(APC/C).1 This is important as it suggests cancer metabolism not only to be a consequence of tumor growth,but also one of its *** its initial discovery over 200 years ago,lactate has sustained the interest of a wide range of research fields due to its significance as energy fuel,redox buffer and signaling molecule.2 High quantities of lactate are produced through glycolysis in muscle during exercise,through bacterial lactic acid fermentation,and perhaps most famously,by rapidly growing tumor cells.

Rehabilitation of degraded areas in northeastern Patagonia, Argentina: Effects of environmental conditions and plant functional traits on performance of native woody species

引用

Journal of Arid Land 2020年第4期12卷 653-665页

作者： Juan M ZEBERIO carolina A PÉREZ National University of Río Negro Atlantic HeadquartersCenter for Environmental Studies from Norpatagonia(CEANPa)Viedma 8500Argentina National Council of Scientific and Technical Research(CONICET) Viedma 8500Argentina Ecological and Environmental Systems Research Laboratory(LISEA) National University of La PlataLa Plata 1900Argentina

Degradation processes affect a vast area of arid and semi-arid lands around the world and damage the environment and people′s health. Degradation processes are driven by human productive activities that cause direct and indirect effects on natural resources, such as species extinction at regional scale, reduction and elimination of vegetation cover, soil erosion, etc. In this context, ecological rehabilitation is an important tool to recover key aspects of the degraded ecosystem. Rehabilitation trials rely on the use of native plant species with characteristics that allow them to obtain high survival and growth rates. The aim of this work was to assess the survival and growth of native woody species in degraded areas of northeastern Patagonia and relate them to plant functional traits and environmental variables. We observed high early and late survival rates, and growth rates in Prosopis flexuosa DC. var. depressa F.A. Roig and Schinus johnstonii F.A. Barkley, and low values in Condalia microphylla Cav. and Geoffroea decorticans(Gillies ex Hook. & Arn.) Burkart. Early survival rates were positively associated with specific leaf area(SLA) and precipitation, but negatively associated with wood density, the maximum mean temperature of the warmest month and the minimum mean temperature of the coldest month. Late survival rates were positively associated with SLA and soil organic matter, but negatively associated with plant height and precipitation. The temperature had a positive effect on late survival rates once the plants overcame the critical period of the first summer after they were transplanted to the field. Prosopis flexuosa and S. johnstonii were the most successful species in our study. This could be due to their functional traits that allow these species to acclimatize to the local environment. Further research should focus on C. microphylla and G. decorticans to determine how they relate to productive conditions, acclimation to environmental stress, auto-eco
