People with aortic/prosthetic valve endocarditis are a high-risk cohort of patients who present a challenge for all medically involved disciplines and who can be treated by various surgical techniques. We analyzed the results of treatment of root endocarditis with Medtronic Freestyle® in full-root technique over 19 years (1999-2018) and compared them against treatment with other tissue valves. Comparison was made with propensity score matching, using the nearest neighbor method. Various tests were performed as suited for adequate analyses. Fifty-four patients in the Medtronic Freestyle group (FS group) were matched against 54 complex root endocarditis patients treated with other tissue valves (Tissue group). Hospital mortality was 9/54 (16.7%) in the FS group vs. 14/54 (25.6%) in the Tissue group (P=0.24). Cox regression performed for early results demonstrated coronary heart disease (P=0.004, odds ratio 2.3), among others, influencing early mortality. Recurrent infection was low (1.8% for FS and Tissueding infective tissue from the bloodstream, possibly with benefits, concerning bacteremia and recurrent infection. Furthermore, the use of the stentless bioroot offers varying treatment options in case of future valve degeneration.Melanoma, which originates from the transformation of normal melanocytes, is one of the three main types of skin cancer. We aimed to explore the functions of SNHG16 and miR-132 in melanoma. CCK-8, Transwell assays were used to measure the viability and migration, respectively. Spearman's correlation analysis was performed to analyze the relationship between the expression of SNHG16, miR-132 and LAPTM4B in melanoma tissues. SNHG16 was overexpressed, and miR-132 was low expressed in melanoma tissues and cell lines. Moreover, overexpression of SNHG16 was associated with poor prognosis of melanoma patients. The expression of SNHG16 had a negative connection with the expression of miR-132, and it had a positive relationship with the expression of LAPTM4B in melanoma tissues. Knockdown of SNHG16 or overexpression of miR-132 inhibited SK-MEL-2 cell proliferation and migration. In addition, we confirmed that SNHG16 directly binding to miR-132 promotes the expression of LAPTM4B, facilitating the tumorigenesis of melanoma. SNHG16 promotes the expression of LAPTM4B by sponging miR-132, thereby acting as an oncogene in melanoma. This study demonstrated that the lncRNA-miRNA-mRNA signal cascade existed in melanoma, which may help elucidate the tumorigenesis and development mechanism of melanoma. The novel coronavirus (coronavirus disease 2019 [COVID-19]) outbreak began in China in December last year, and confirmed cases began occurring in Korea in mid-February 2020. Since the end of February, the rate of infection has increased greatly due to mass (herd) infection within religious groups and nursing homes in the Daegu and Gyeongbuk regions. This mass infection has increased the number of infected people more rapidly than was initially expected; the epidemic model based on existing studies had predicted a much lower infection rate and faster recovery. The present study evaluated rapid infection spread by mass infection in Korea and the high mortality rate for the elderly and those with underlying diseases through the Susceptible-Exposed-Infected-Recovered-Dead (SEIRD) model. The present study demonstrated early infection peak occurrence (-6.3 days for Daegu and -5.3 days for Gyeongbuk) and slow recovery trend (= -1,486.6 persons for Daegu and -223.7 persons for Gyeongbuk) between the actual and the epidemic model for a mass infection region compared to a normal infection region. The analysis of the time difference between infection and recovery can help predict the epidemic peak due to mass (or normal) infection and can also be used as a time index to prepare medical resources.
