简介：AbstractObjective:To provide an overview of the current available music assessment tools after cochlear implantation (CI); to report on the utilization of music assessments in the literature; to propose potential future directions in music assessment after CI.Methods:A thorough search was performed in PubMed, Embase, and The Cochrane Library through October 31, 2020. MeSH search terms, keywords, and phrases included "cochlear implant," "cochlear prosthesis," "auditory prosthesis," "music," "music assessment," "music questionnaire," "music perception," "music enjoyment, and "music experience." Potentially relevant studies were reviewed for inclusion, with particular focus on assessments developed specifically for the cochlear implant population and intended for widespread use.Results/conclusions:Six hundred and forty-three studies were screened for relevance to assessment of music experience among cochlear implantees. Eighty-one studies ultimately met criteria for inclusion. There are multiple validated tools for assessment of music experience after cochlear implantation, each of which provide slightly differing insights into the patients’ subjective and/or objective post-activation experience. However, no single assessment tool has been adopted into widespread use and thus, much of the literature pertaining to this topic evaluates outcomes non-uniformly, including single-use assessments designed specifically for the study at hand. The lack of a widely accepted universal tool for assessment of music limits our collective understanding the contributory and mitigating factors applicable to current music experience of cochlear implantees, and limits our ability to uniformly evaluate the success of new implant technologies or music training paradigms.

简介：AbstractSevere fever with thrombocytopenia syndrome (SFTS) was first detected in China in 2009. The incidence of SFTS increases year by year, and there is no effective treatment. Considering that the reported prevalence of SFTSV infection varies from region to region, we aimed to quantitatively evaluate the epidemic characteristics of SFTSV infection in China from 2010 to 2020, including the distribution differences in infectious season, sex, age, occupation, and region. A meta-analysis framework was used to search for the related published data with keywords in electronic databases (CNKI, WanFang, CBM, and PubMed). According to the PRISMA statement, the studies that included SFTS diagnosed in China were analyzed. Furthermore, we used Revman and Stata to merge statistical effects, and used I2 and P-values for heterogeneity test and quality assessment. Eleven studies containing 4,932 cases confirmed by SFTSV infection were included in this meta-analysis. The ratio of male-to-female is 1.04 to 1. Cases were concentrated between 40 and 80 years of age (MD = 92%, 95%CI: 91%-93%). Farmers are at the highest risk of SFTSV infection (MD = 84%, 95%CI: 77%-90%). The risk of infection for consecutive period of April-August was significantly higher than the sum of the remaining months (MD = 82%, 95%CI: 78%-85%). In addition, the patient has an extensive history of exposure, including living in the mountains, exposure to ticks, livestock, mouse and the patient. We came to the conclusion that SFTSV is transmitted primarily through tick bites in China, so middle-aged and older adults living in mountains regions are at the highest risk for SFTSV infection in April through August each year.

简介：AbstractBackground:Thyroid dysfunction is associated with cardiovascular diseases. However, the role of thyroid function in lipid metabolism remains partly unknown. The present study aimed to investigate the causal association between thyroid function and serum lipid metabolism via a genetic analysis termed Mendelian randomization (MR).Methods:The MR approach uses a genetic variant as the instrumental variable in epidemiological studies to mimic a randomized controlled trial. A two-sample MR was performed to assess the causal association, using summary statistics from the Atrial Fibrillation Genetics Consortium (n = 537,409) and the Global Lipids Genetics Consortium (n = 188,577). The clinical measures of thyroid function include thyrotropin (TSH), free triiodothyronine (FT3) and free thyroxine (FT4) levels, FT3:FT4 ratio and concentration of thyroid peroxidase antibodies (TPOAb). The serum lipid metabolism traits include total cholesterol (TC) and triglycerides, high-density lipoprotein, and low-density lipoprotein (LDL) levels. The MR estimate and MR inverse variance-weighted method were used to assess the association between thyroid function and serum lipid metabolism.Results:The results demonstrated that increased TSH levels were significantly associated with higher TC (β = 0.052, P = 0.002) and LDL (β = 0.041, P = 0.018) levels. In addition, the FT3:FT4 ratio was significantly associated with TC (β = 0.240, P = 0.033) and LDL (β = 0.025, P = 0.027) levels. However, no significant differences were observed between genetically predicted FT4 and TPOAb and serum lipids.Conclusion:Taken together, the results of the present study suggest an association between thyroid function and serum lipid metabolism, highlighting the importance of the pituitary-thyroid-cardiac axis in dyslipidemia susceptibility.
