狂犬病口服疫苗对消除人间狂犬病的重要作用北大核心CSCD

狂犬病严重威胁人类生命,控制狂犬病需要从病毒的源头着手。在狂犬病毒的多种宿主中,犬科动物所占比例最大。因此,消除狂犬病的关键是对犬的免疫覆盖率达到70%以上。事实证明,通过注射灭活疫苗对犬只形成免疫屏障是一件困难的事情。采用口服疫苗策略控制野生动物狂犬病的成功案例给大家提供了新的思路,因此世界卫生组织建议采用狂犬病口服疫苗对犬进行免疫,用以提高犬只的免疫覆盖率,从而达到2030年消除和控制狂犬病的目的。     

Preventing human papilloma virus infection: another vaccination success

Human papillomavirus (HPV) is the commonest sexually transmitted infection. It has over 200 genotypes which, depending on the site of infection and type of virus, can give rise to cancers or warts. HPV infection is a prerequisite for cervical cancer and is associated to varying degrees with other anogenital cancers and, increasingly, with cancers of the oropharynx. It is also associated with anogenital warts which, while not life threatening, cause considerable morbidity. HPV vaccines have been available since 2006 and by mid-2021 have been introduced into over 110 countries. Trials and real world data have shown them to be safe and highly effective at preventing infection with HPV and anogenital warts. Data are also accumulating showing impressive reductions in cervical cancer. In UK, HPV vaccine mainly offered to girls and boys aged 12–13 years in a school-based programme. Uptake is generally high, but inequalities persist and there are concerns about the impact of a recent significant decline in uptake due to school closures arising from the COVID pandemic. HPV vaccine programmes have been significantly impacted by vaccine hesitancy in some countries, but experience in the Republic of Ireland and Denmark has shown that with involvement of the community, this can be successfully addressed. Modelling estimates that, by 2058, the vaccine will have prevented over 64,000 HPV-related cervical cancers and almost 50,000 other HPV-related cancers. The introduction of a vaccine containing nine HPV strains will further increase the number of cancers prevented. This short article outlines how HPV vaccination in adolescence is helping prevent serious illness in adult life.     

Health Insurance Status and Psychological Distress among US Adults Aged 18–64 Years

The purpose of this research was to examine the relationship between psychological distress and aspects of health insurance status, including lack of coverage, types of coverage and disruption in coverage, among US adults. Data from the 2001–2010 National Health Interview Survey were used to conduct analyses representative of the US adult population aged 18–64 years. Multivariate analyses regressed psychological distress on health insurance status while controlling for covariates. Adults with private or no health insurance coverage had lower levels of psychological distress than those with public/other coverage. Adults who recently (≤1 year) experienced a change in health insurance status had higher levels of distress than those who had not recently experienced a change. An interaction effect indicated that the relationship between recent change in health insurance status and distress was not dependent on whether an adult had private versus public/other coverage. However, for adults who had not experienced a change in status in the past year, the average absolute level of distress is higher among those with no coverage versus private coverage. Although significant relationships between psychological distress and health insurance status were identified, their strength was modest, with other demographic and health condition covariates also being potential sources of distress.

Operationalizing universal health coverage in Nigeria through social health insurance

Nigeria faces challenges that delay progress toward the attainment of the national government''s declared goal of universal health coverage (UHC). One such challenge is system-wide inequities resulting from lack of financial protection for the health care needs of the vast majority of Nigerians. Only a small proportion of Nigerians have prepaid health care. In this paper, we draw on existing evidence to suggest steps toward reforming health care financing in Nigeria to achieve UHC through social health insurance. This article sets out to demonstrate that a viable path to UHC through expanding social health insurance exists in Nigeria. We argue that encouraging the states which are semi-autonomous federating units to setup and manage their own insurance schemes presents a unique opportunity for rapidly scaling up prepaid coverage for Nigerians. We show that Nigeria''s federal structure which prescribes a sharing of responsibilities for health care among the three tiers of government presents serious challenges for significantly extending social insurance to uncovered groups. We recommend that rather than allowing this governance structure to impair progress toward UHC, it should be leveraged to accelerate the process by supporting the states to establish and manage their own insurance funds while encouraging integration with the National Health Insurance Scheme.     

A Robust Approach for Blind Detection of Balanced Chromosomal Rearrangements with Whole‐Genome Low‐Coverage Sequencing

Balanced chromosomal rearrangement (or balanced chromosome abnormality, BCA) is a common chromosomal structural variation. Next‐generation sequencing has been reported to detect BCA‐associated breakpoints with the aid of karyotyping. However, the complications associated with this approach and the requirement for cytogenetics information has limited its application. Here, we provide a whole‐genome low‐coverage sequencing approach to detect BCA events independent of knowing the affected regions and with low false positives. First, six samples containing BCAs were used to establish a detection protocol and assess the efficacy of different library construction approaches. By clustering anomalous read pairs and filtering out the false‐positive results with a control cohort and the concomitant mapping information, we could directly detect BCA events for each sample. Through optimizing the read depth, BCAs in all samples could be blindly detected with only 120 million read pairs per sample for data from a small‐insert library and 30 million per sample for data from nonsize‐selected mate‐pair library. This approach was further validated using another 13 samples that contained BCAs. Our approach advances the application of high‐throughput whole‐genome low‐coverage analysis for robust BCA detection—especially for clinical samples—without the need for karyotyping.
