for the BaSICS investigators and the BRICNet members IMPORTANCE Slower intravenous fluid infusion rates could reduce the formation of tissue edema and organ dysfunction in critically ill patients; however, there are no data to support different infusion rates during fluid challenges for important outcomes such as mortality.OBJECTIVE To determine the effect of a slower infusion rate vs control infusion rate on 90-day survival in patients in the intensive care unit (ICU). DESIGN, SETTING, AND PARTICIPANTS Unblinded randomized factorial clinical trial in 75 ICUs in Brazil, involving 11 052 patients requiring at least 1 fluid challenge and with 1 risk factor for worse outcomes were randomized from May 29, 2017, to March 2, 2020. Follow-up was concluded on October 29, 2020. Patients were randomized to 2 different infusion rates (reported in this article) and 2 different fluid types (balanced fluids or saline, reported separately).INTERVENTIONS Patients were randomized to receive fluid challenges at 2 different infusion rates; 5538 to the slower rate (333 mL/h) and 5514 to the control group (999 mL/h). Patients were also randomized to receive balanced solution or 0.9% saline using a factorial design. MAIN OUTCOMES AND MEASURESThe primary end point was 90-day survival.RESULTS Of all randomized patients, 10 520 (95.2%) were analyzed (mean age, 61.1 years [SD, 17.0 years]; 44.2% were women) after excluding duplicates and consent withdrawals. Patients assigned to the slower rate received a mean of 1162 mL on the first day vs 1252 mL for the control group. By day 90, 1406 of 5276 patients (26.6%) in the slower rate group had died vs 1414 of 5244 (27.0%) in the control group (adjusted hazard ratio, 1.03; 95% CI, 0.96-1.11; P = .46). There was no significant interaction between fluid type and infusion rate (P = .98).CONCLUSIONS AND RELEVANCE Among patients in the intensive care unit requiring fluid challenges, infusing at a slower rate compared with a faster rate did not reduce 90-day mortality. These findings do not support the use of a slower infusion rate.

Doenças negligenciadas são doenças tropicais endêmicas, especialmente entre as populações pobres da África, Ásia e América Latina e que apresentam em alguns casos, ações preventivas e tratamentos já conhecidos. No entanto por afetarem principalmente a população que vive na pobreza, esses indivíduos são privados do tratamento indicado. Desta forma, o trabalho visa reunir dados de estudos já publicados, sintetizando assim, uma revisão bibliográfica da literatura que possibilita uma melhor compreensão da hiperinfestação por Strongyloides stercoralis bem com uma avaliação dos métodos utilizados para o diagnóstico da doença. Realizamos um levantamento de artigos científicos publicados, a partir de banco de dados confiáveis como Pubmed, Bireme e Scielo, dentre 1974 á 2017. Ao fim do trabalho observamos que todos os doentes diagnosticados com estrongiloidíase, mesmo que assintomáticos, devem ser tratados e todos os doentes com fatores de risco para a infecção devem ser rastreados, especialmente aqueles sob corticoterapia ou outros regimes imunossupressores.

AbstractBackground: Biochemical and hematological parameters are important tools for assessing the physiological profile of vital organs, and can be recorded to create reference values used for clinical diagnosis of diseases. Many research laboratories lack the means to establish their own set of reference parameters for use in their research, and while there are articles in the literature that discuss laboratory parameters for healthy BALB/c mice, few studies address the evaluation of these parameters in pathological situations, such as in mice inoculated with Ehrlich tumor.Method: BALB/c-FMABC mice previously inoculated with Ehrlich tumor were maintained under appropriate conditions. Blood samples were taken for analysis of hematological parameters using automated and semi-automated equipment to create a set of the animal welfare parameters for evaluation. Result:Results were obtained for all the hematological parameters for all groups analyzed. These showed: statistically significant differences between the initial and final tumor weight; comparable initial tumour volume and weight; an increase in leukocytes in the 7-day group with a characteristic predominance of lymphocytes and neutrophils; statistically significant changes in RDW in the 21-day group and in the welfare parameters in the 28-day group. Conclusion:The study successfully defined and established reference values for hematological and welfare parameters for all groups analyzed.

With the rising in life expectancy and the consequent population aging, degenerative chronic diseases have been figured as the major cause of morbidity and mortality in the world. It is believed that the production of a polymeric matrix composed of chitosan and gelatin may be an alternative to obtain a carrier base of heparin, with the prospective objective of applying these materials as an alternative to the conventional therapeutic resources biomedical. Based on the results, it can be concluded that the interaction between chitosan, gelatin, and heparin demonstrating a satisfactory result by the methodologies that were applied, making the study hypothesis concrete., certifying the use of a methodology for including heparin in a biodegradable polymeric base. Thus, expanding the alternatives for possible alternatives to the conventional therapeutic resources of vascular diseases with the application of the developed materials.
