This study aimed to develop and validate a bedside risk analysis system for predicting the clinical severity and prognosis of patients with COVID-19. Camptothecin chemical structure A total of 444 COVID-19 patients were included and were randomly assigned into two groups at a ratio of 21 as derivation and validation groups. The new scoring system comprised of eight variables, which included history of having malignant diseases, history of having diabetes mellitus, dyspnea, respiratory rate of >24 bpm, C-reactive protein (CRP) of >14 mg/L, white blood cell count of >8×109/L, platelets count of less then 180×1012/L, and lymphocyte count of less then 1×109/L. The sensitivity analysis revealed that this new score performed better than the sequential organ failure assessment (SOFA) score at the first day of admission. The receiver characteristic curve analysis revealed that this score predicted severe cases of COVID-19 infection at 0.831 (95% confidence interval 0.783-0.879) and 0.798 (95% confidence interval 0.727-0.869) of the area under the curve in the derivation and validation group. The proposed risk score system is a fairly reliable and robust tool for evaluating the severity and prognosis of patients with COVID-19. This may help to early identify severe patients with poor prognosis, who may require more intense interventions.Routine vaccination has proven to be highly effective in reducing the incidence of mumps. However, sporadic cases and/or mumps outbreaks do occur in children and adolescents younger than 15 years old, particularly among those 5-9 years old. To explore the characteristics of such outbreaks in Henan Province, clinical data of patients infected with MuV were collected, and the isolated MuV strains were phylogenetically analyzed. Of a total of 426 samples, MuV RNA targeting the small hydrophobic (SH) gene was detected in 153 samples. MuV-positive cases in each age group ( less then 5, 5-9,10-15, 16-19, and ≥ 20) accounted for 1%, 17%, 12%, 2% and 4% of the total number of cases, respectively. Phylogenetic analysis based on the SH gene sequences indicated that all of the isolated strains were of genotype F and isolates in the the same subcluster and identical SH gene sequences tended to be derived from the same community or municipalities when analyzed alongside epidemiological data. In conclusion, the incidence of mumps in Henan Province is high. The data provided in this study might promote further research in the clarification of specific cause of mumps outbreaks and which will facilitate the implementation of effective prevention and control measures.The prevalence of quinolone- and macrolide-resistant Group B Streptococcus (GBS) is increasing worldwide, but the relationship between GBS resistance to these antibiotics and patient outcome remains unclear. Therefore, we evaluated whether blood stream infection caused by quinolone- or macrolide-resistant GBS is associated with high mortality. Our findings in 77 patients with GBS bacteremia demonstrate that quinolone and macrolide resistance may not be risk factors for 30-day mortality.The reported prevalence of genital chlamydia trachomatis infection (GCTI) in low income countries is much lower than that in high income countries. This study surveyed the prevalence of GCTI in 456 hospitals in Shandong province, China in December 2018. Among the hospitals surveyed, antigen testing, PCR testing, and either antigen or PCR testing were available in 200 (43.9%), 88 (19.3%) and 268 (58.8%) hospitals, respectively. PCR testing was more available in tertiary hospitals than in primary and secondary hospitals (X2=28.560, P=0.000). Significant differences were observed in the availability of antigen testing (X2=15.708, P=0.003), PCR testing (X2=22.494, P=0.000), and either antigen or PCR testing (X2=21.729, P=0.000) among different types of hospital. In 2018, 1532 cases of GCTI were reported in 99 hospitals. Tertiary hospitals reported more cases than primary and secondary hospitals (X2=24.082, P=0.000). The distribution of different types of hospital that reported GCTI cases was consistent with that of hospitals that provided laboratory testing for GCTI. Antigen and PCR testing were only available in 200 (43.9%) and 88 (19.3%) hospitals, respectively. Results highlighted that the availability of laboratory testing for GCTI in Shandong Province was poor, suggesting that the prevalence of GCTI in the province had been sorely underestimated.Coronavirus disease 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus (SARS-CoV-2). First identified in December 2019 in Wuhan, China, it has since become a global pandemic. Complications of COVID-19 are not limited to the pulmonary system, but include also neurologic manifestations, such as stroke. We report two cases with coincident presentation of COVID-19 and cerebrovascular accident. Further studies are needed for a comprehensive understanding of the neurological pathology of COVID-19 and its effects on the nervous system, but stroke teams should be wary of the fact that COVID-19 patients can present with cerebrovascular accidents.The quadrivalent meningococcal polysaccharide diphtheria toxoid conjugate vaccine (Men-ACWY-D) is licensed in Japan since 2014. An earlier registration study demonstrated the immunogenicity of one dose in Japanese adults. Immunogenicity against serogroup C was lowest. Determination of the potential to increase the serogroup C response with a second dose was of interest. This study (NCT02591290) evaluated the safety and immunogenicity of two doses administered eight weeks apart to 60 healthy Japanese adults aged 20-55 years. Blood samples were collected 28-35 days after each vaccination. Immunogenicity endpoints included seroprotection and seroconversion rates. Safety assessments included systemic adverse events (AEs), non-serious AEs, and serious AEs. Fifty-eight (96.7%) participants completed the study. Seroprotection rates for serogroups A, C, W, and Y before vaccination were 76.8%, 26.8%, 26.8%, and 50.0%, increasing to 100%, 83.9%, 91.1%, and 96.4% and 100%, 92.9%, 94.6%, and 94.6%, respectively, after two doses.
