ledge, the specific serology assays for the detection of the tiger IgG antibody have not yet been established. The HRP-anti-tiger IgG has been produced for the purpose of developing the specific immunoassays for tigers. Remarkably, an in-house indirect ELISA based on VP2 subunit antigen has been successfully developed in this study, providing a potentially valuable serological tool for the effective detection of tiger antibodies.
COVID-19 is an extremely severe infectious disease. However, few studies have focused on the epidemiological and clinical characteristics of pediatric COVID-19. This study conducted a retrospective review of the epidemiological and clinical features of COVID-19 in children.

A retrospective study was conducted on children with a definite diagnosis of COVID-19 in mainland China using the web crawler technique to collect anonymous COVID-19 updates published by local health authorities.

Three hundred forty-one children aged 4 days to 14 years with a median age of 7 years were included. Sixty-six percent of pediatric patients were infected via family members with COVID-19. The median incubation period was 9 days (interquartile range, 6 to 13). Asymptomatic cases accounted for 5.9%, of which 30% had abnormal chest radiologic findings. A majority of pediatric COVID-19 cases showed mild to moderate clinical features, and only a few developed severe or critical diseases (0.6% and 0.3%, respectively). Fever (77.9%) and cough (32.4%) were the predominant presenting symptoms of pediatric COVID-19. The pediatric patients had fewer underlying diseases and complications than adults. The treatment modalities for pediatric COVID-19 patients were not as complex as those of adult COVID-19 patients. The overall prognosis of pediatric COVID-19 was benign with a decent recovery. The median time from onset to cure was 16 days (interquartile range, 13 to 21).

Compared to adults, COVID-19 in children has distinct features of epidemiology and clinical manifestations. The findings from this study might help to guide the development of measures to prevent and treat this ongoing global pandemic.

Insufficient transparency in prioritization of health services, multiple health insurance organizations with various and not-aligned policies, plus limited resources to provide comprehensive health coverage are among the challenges to design appropriate Health Insurance Benefit Package (HIBP) in Iran. This study aims to analyze Policy Process of Health Insurance Benefit Package in Iran.

Data were collected through semi-structured interviews with 25 experts, plus document analysis and observation, from February 2014 until October 2016. Using both deductive and inductive approaches, two independent researchers conducted data content analysis. We used MAXQDA.11 software for data management.

We identified 10 main themes, plus 81 sub-themes related to development and implementation of HIBP. These included lack of transparent criteria for inclusion of services within HIBP, inadequate use of scientific evidence to determine the HIBP, lack of evaluation systems, and weak decision-making process. We propose 11 smic factors had the greatest impact on the implementation of HIBP. To define a cost-effective HIBP in Iran, it is pivotal to develop transparent and evidence-based guidelines about the processes and the stewardship of HIBP, which are in line with upstream policies and societal characteristics. selleck chemicals In addition, the possible conflict of interests and its harms should be minimized in advance.
Health service managers are integral to supporting the effective and efficient delivery of services. Understanding their competencies is essential to support reform and improvement of healthcare provision in China. This paper examines the characteristics and educational background of senior managers working in the community health and hospital sectors in China. We also examine their levels of commitment to continued professional development and continuous education.

A self-administered paper-based questionnaire was administered to 477 level I, II and III managers in community health services and public hospitals in China. The response rate was over 80%.

Findings demonstrate significant differences in terms of educational background and commitment to ongoing professional development between the managers in China across levels of management, and between the community and hospital sectors. Hospital managers tend to be older; hospital managers at higher management levels are predominantly male but predominao design appropriate professional development for China's health services managers. In addition, the importance of managerial tasks across sectors and management levels requires further investigation.
Extraintestinal pathogenic E. coli (ExPEC) is a common gram-negative organism causing various infections, including urinary tract infections (UTIs), bacteremia, and neonatal meningitis. The cjrABC-senB gene cluster of E. coli contributes to ExPEC virulence in the mouse model of UTIs. Consistently, the distribution of cjrABC-senB is epidemiologically associated with human UTIs caused by E. coli. cjrABC-senB, which has previously been proposed to encode an iron uptake system, may facilitate ExPEC survival in the iron availability-restricted urinary tract. Given that the bloodstream is also an iron limited environment to invading bacteria, the pathogenic role of cjrABC-senB in ExPEC bacteremia, however, remains to be investigated.

The ability of ExPEC RS218 strains with and without cjrABC-senB to survive in the mouse bloodstream and human serum was evaluated. Subsequently, the role of this gene cluster in the ExPEC interaction with the complement system was evaluated. Finally, the distribution of cjrABC-senB and fecal isolates showed no significant difference. Consistently, this epidemiological investigation suggests that cjrABC-senB does not contribute to E. coli bacteremia in humans.

The contribution of cjrABC-senB to the pathogenesis of ExPEC is niche dependent and contradictory because the genes facilitate ExPEC UTIs but hinder bacteremia. The contradictory niche-dependent characteristic may benefit the development of novel strategies against E. coli-caused infections.
