Anti-inflammatory compound shows therapeutic safety and efficacy against flavivirus infection. Antimicrob Agents Chemother. 2019 Oct 21;: Authors: Chuang FK, Huang SM, Liao CL, Lee AR, Lien SP, Chiu YL, Chang TH, Tsai PL, Lin RJ, Shih CC, Tsai YJ, Lin GJ, Yen LC Abstract Flaviviruses comprise several medically important viruses, including Japanese encephalitis virus, West Nile virus, dengue virus (DENV), yellow fever virus and Zika virus (ZIKV). A large outbreak of DENV and ZIKV occurred recently, leading to many cases of illness and death. However, despite decades of efforts, we have no clinically specific therapeutic drugs against DENV and ZIKV. Previous studies showed that inflammatory responses play a critical role in dengue and Zika pathogenesis. Thus, in this study, we examined a series of novel anti-inflammatory compounds and found that treatment with compound 2d could dose-dependently reduce viral protein expression and viral progeny production in HEK-293 and Raw264.7 cells with four serotypes of DENV and ZIKV infection. As well, considering medication safety, compound 2d could not suppress cyclooxygenase-1 (COX-1) enzymatic activities and thus could prevent bleeding side effect. Moreover, compound 2d significantly inhibited COX-2 enzymatic activities and prostaglandin E2 levels, associated with viral replication, as compared with a selective COX-2 inhibitor, celecoxib. Furthermore, administering 5 mg/kg compound 2d to DENV-2-infected AG129 mice ...

Authors: Zhao N, Xiang Q, Liu Z, Zhao X, Cui Y Abstract INTRODUCTION: There remains an unmet need for better anticoagulants. The phase I clinical trial is of great significance in the development of anticoagulants, and the design is special. This system review aims to provide insights for the design of future phase I clinical trials of anticoagulants. AREAS COVERED: We searched the database PubMed and ClinicalTrail.gov website, to collate the phase I clinical trial of anticoagulants in healthy people. The study protocol, inclusion exclusion criteria, safety and pharmacodynamic indexes were reviewed. EXPERT ...

Authors: Jang Y, Kim DW, Yang KI, Byun JI, Seo JG, No YJ, Kang KW, Kim D, Kim KT, Cho YW, Lee ST, Drug Committee of Korean Epilepsy Society Abstract Autoimmune epilepsy is a newly emerging area of epilepsy. The concept of "autoimmune" as an etiology has recently been revisited thanks to advances in autoimmune encephalitis and precision medicine with immunotherapies. Autoimmune epilepsy presents with specific clinical manifestations, and various diagnostic approaches including cerebrospinal fluid analysis, neuroimaging, and autoantibody tests are essential for its differential diagnosis. The diagnosis is o...

Authors: Fentie K, Wakayo T, Gizaw G Abstract Background: Anemia defined as a low blood hemoglobin concentration is public health importance. The adolescence age group is the most neglected in public health and nutrition research as priorities are usually given to pregnant women, lactating mothers, and their children less than 2 years. Current Ethiopian Food and Nutrition policy included adolescent girls in the most at-risk group for nutritional demands; however, only a few published studies have assessed a deficiency of anemia and associated factors to tackle the intergenerational cycle of malnutrition.

Only four cases of human S. condimenti infections have been reported to date. We herein report the first case of spondylodiscitis caused by S. condimenti. A 72-year-old Japanese man complaining of lower back pain and numbness in his legs was diagnosed with spondylodiscitis. A computed tomography (CT)-guided biopsy was performed.
