乙肝孕妇血清标志物模式与HBV-DNA载量及肝功能关系研究

目的探讨乙肝孕妇血清标志物模式、HBV-DNA载量及肝功能三者之间的关系,为孕期乙肝病毒感染情况的监控和乙肝病毒母婴传播的预防提供参考。方法选取2019年1月-11月在我院产检的767例乙肝表面抗原阳性孕妇的乙肝血清标志物模式、肝功能指标的丙氨酸氨基转移酶(alamine aminotransferase,ALT)及HBVDNA载量进行研究,探讨三者间的关系。结果HBsAg、HBeAg、HBcAb阳性组孕妇HBV-DNA阳性率及病毒载量均高于其余两组(P<0.05);ALT升高程度与HBV-DNA载量具有一定相关性(r=0.255,χ^2=80.150,P=0.000);HBeAg阳性组和HBeAg阴性组间HBV-DNA阳性率、ALT异常率差异均有统计学意义。结论HBV-M、HBV-DNA与肝功能之间有一定的相关性,大三阳孕妇中高病毒载量比例高,应加强乙肝孕妇孕期各项指标的监测,必要时进行干预治疗。     

Inter-ictal assay of peripheral circulating inflammatory mediators in migraine patients under adjunctive cervical non-invasive vagus nerve stimulation (nVNS): A proof-of-concept study

Objective

To assay peripheral inter-ictal cytokine serum levels and possible relations with non-invasive vagus nerve stimulation (nVNS) responsiveness in migraineurs.

Key Social Determinants to Narrow the Gap between Health-adjusted Life Expectancy and Life Expectancy in Megacities

ObjectiveImprovement in the quality of life is reflected in the narrowing of the gap between health-adjusted life expectancy (HALE) and life expectancy (LE). The effect of megacity expansion on narrowing the gap is rarely reported. This study aimed to disclose this potential relationship.MethodsAnnual life tables were constructed from identified death records and population counts from multiple administrative sources in Guangzhou, China, from 2010 to 2020. Joinpoint regression was used to evaluate the temporal trend. Generalized principal component analysis and multilevel models were applied to examine the county-level association between the gap and social determinants.ResultsAlthough LE and HALE in megacities are increasing steadily, their gap is widening. Socio-economic and health services are guaranteed to narrow this gap. Increasing personal wealth, a growing number of newborns and healthy immigrants, high urbanization, and healthy aging have helped in narrowing this gap.ConclusionIn megacities, parallel LE and HALE growth should be highly considered to narrow their gap. Multiple social determinants need to be integrated as a whole to formulate public health plans.     

Intra-seasonal variation of injury patterns among German Bundesliga soccer players

ObjectiveHigh fluctuations in injury-risk during the playing season in soccer have been reported. As seasons are structured in periods with homogenous loads and intensities, we investigated injury-risk over season periods, contrarily to previous studies adopting a month-based approach.DesignCohort study; Level of evidence, 2.MethodsIncidence-rate ratios (IRRs) for match and training injuries were compared across six consecutive seasons of German Bundesliga, divided into six periods each: Pre-season (PS), winter-break (WB), quarter 1–4: (Q1–Q4).ResultsSignificant variations in injury-risk were observed for match and training injuries. IRRs in matches was 1.30 (95% CI: 1.11–1.53) times higher in Q3 and 1.53 (95% CI: 1.31–1.78) higher in Q4 compared to Q1. For training injuries, IRR peaked in Q1 and Q3 followed by a marked decrease in each subsequent quarter. Compared to Q4, IRR was 1.62 (95% CI: 1.40–1.86) times higher during Q3 and 1.78 (95% CI: 1.53–2.07) times higher in Q1. IRR was significantly higher in the competitive season compared to pre-season across match (IRR: 2.00, 95% CI: 1.30–3.00) and training (IRR: 1.27, 95% CI: 1.11–1.43) injuries.ConclusionsThe increased match IRRs later during the season indicate that, in practice, coaches should consider putting even more emphasis on recovery in the last part of the season. Moreover, training injuries seem to indicate a carry-over effect. Further studies need to investigate how training during preparatory phases can be implemented in a way that prevents injuries during the competitive season.

Dostoevsky's epilepsy: A case report and comparison

The Russian writer Dostoevsky (1821–1881) suffered from a rare form of temporal lobe epilepsy termed “ec-static epilepsy.” Dostoevsky used his epileptic experiences to create Prince Myshkin, the protagonist of The Idiot. The recent case of a patient who experienced ecstatic epilepsy as a result of a temporal lobe brain tumor is presented and compared with that of Prince Myshkin. Reading Dostoevsky can give the contemporary physician an insight into the inner life of an epileptic patient — an example of how art can directly benefit medical practice.
