Filter by:In November 2019, there were a lot of cases of an acute respiratory illness (then named at February 11th as COVID_19) which first case was reported in Wuhan, China,The SARS COV-2 had been spread in a fast way to involve whole world, As it's obvious that Colchicine is a drug that is most commonly and widely used to treat and prevent acute attacks of Gout, other crystal induced arthropathy,colchicine has important role in inhibiting activation of NLRP3 inflammasome these lead to decrease cytokine production , aim of study To evaluate whether colchicine is effective in the treatment of COVID-19 cases. And to measure the effectiveness of colchicine in alleviating and controlling pulmonary and extra pulmonary complications of COVID-19
The study evaluates the effects of Helichrysum italicum and Helichrysum Arenarium on different components of the metabolic syndrome. The components of metabolic syndrome will be measured at baseline and four weeks after daily consumptions of either Helichrysum italicum or either Helichrysum Arenarium, and after two weeks of washout. In addition, stool samples will be also taken at baseline and after four weeks of daily consumtion of either Helichrysum italicum or either Helichrysum Arenarium.
This is a dose optimisation study in healthy adults aged 18-30 who will be experimentally inoculated with SARS-CoV-2. The aim is to cause PCR-confirmed upper respiratory infection in the majority of challenged individuals with minimal or no illness, providing data on the course of COVID-19 and the immune response to SARS-CoV-2 infection. This will establish an optimised dose and study design that will then be used to evaluate the efficacy of treatment and vaccine candidates plus level and duration of immune protection in follow-on trials.
Descending necrotizing mediastinitis (DNM) is the most serious complication of deep neck infections (DNI) with high mortality. The objective of this retrospective study was to evaluate possible prognostic factors for DNM development in deep space neck infections.
This is a laboratory evaluation of a new testing methodology for microbiological diagnosis, whereby participant samples received as part of routine care will be divided between the standard diagnostic pathway and this new pathway: metagenomic next generation sequencing (mNGS). Results obtained from the mNGS pathway will be compared against the standard diagnostic pathway in terms of sensitivity, specificity, accuracy and clinical impact. The samples will be identified at Wellington Southern Community Laboratories (WSCL), which provides laboratory services for Capital and Coast District Health Board, and forwarded to the Institute of Environmental Science and Research (ESR) to undergo mNGS testing.
A randomized control trial was conducted to test the effect of umbilical cord clamping distance on cord separation time and umbilical cord microbial colonization in neonates.
Sepsis is the leading cause of death in intensive care units and a major public health concern in the world. Heparin, a widely used anticoagulant medicine to prevent or treat thrombotic disorders, has been demonstrated to prevent organ damage and lethality in experimental sepsis models. However, the efficacy of heparin in the treatment of clinical sepsis is not consistent. Caspase-11, a cytosolic receptor of LPS, triggers lethal immune responses in sepsis. Recently, we have revealed that heparin prevents cytosolic delivery of LPS and caspase-11 activation in sepsis through inhibiting the heparanase-mediated glycocalyx degradation and the HMGB1- LPS interaction, which is independent of its anticoagulant properties. In our study, it is found that heparin treatment could prevent lethal responses in endotoxemia or Gram-negative sepsis, while caspase-11 deficiency or heparin treatment failed to confer protection against sepsis caused by Staphylococcus aureus, a type of Gram-positive bacterium. It is probably that other pathogens such as Gram-positive bacteria might cause death through mechanisms distinct from that of Gram-negative bacteria. Peptidoglycan, a cell-wall component of Gram-positive bacteria, can cause DIC and impair survival in primates by activating both extrinsic and intrinsic coagulation pathways, which might not be targeted by heparin. We speculate that the discrepancy between the previous clinical trials of heparin might be due to the difference in infected pathogens. Thus, stratification of patients based on the type of invading pathogens might improve the therapeutic efficiency of heparin in sepsis, and this merits future investigations.
This study aims to evaluate the utility of double-ring wound-edge protectors to prevent the development of superficial surgical site infections after open appendectomy.
The aim of this study was to initially evaluate the optimal dose, efficacy, and safety of vitamin D3 for reducing recurrence of recurrent urinary tract infections (rUTIs).
The virological diagnosis of SARS-CoV-2 infection is pivotal for the control of the outbreak by large screening of a- or pauci-symptomatic subjects. Despite nasopharyngeal swabbing tested by RT-PCR is considered as the gold standard, new strategies based on self-samples are considered as valuable alternatives because of their non-invasiveness and ability to be performed in the absence healthcare worker, especially when the subject is asymptomatic and needs to be tested repetitively. The aim of the present project is to evaluate two strategies both based on self-samples: (i) a saliva sample combined to an anterior nare self-swabbing tested by antigenic test versus (ii) a saliva sample tested by RT-PCR. The comparison will be performed during a mass screening of the population of the city of Saint-Etienne (170000 inhabitants), France. The sensitivity of the rapid antigenic test will be evaluated in comparison to that of RT-PCR considered as gold standard.
