Hide Abstract
Background In recent years, the number of varicella cases in adults has significantly increased in Beijing. However, the effect of the vaccination on varicella-related characteristics among adults has not been studied. Methods and Results: Using data from the Infectious Disease Reporting System and the Immunization Information System, we compared the epidemiology and disease severity in breakthrough and unvaccinated varicella cases in adolescents and adults (? 15 year-old) from 2008 to 2011 in Beijing's Fengtai district, China. The results showed that the age (P = 0.003),contact history (90% vs. 73%, P = 0.019) and outbreak cases (10% vs. 1%, P<0.0001) were significantly differently distributed between the two groups and that both the incidence of moderate-to-severe cases (26% vs. 45%, P = 0.035, OR = 0.446) and varicella-associated fever (49% vs. 66%, P = 0.068, OR = 0.534) were either significantly lower or trended to be lower in the breakthrough group than in the unvaccinated group. Additionally,vaccine effectiveness against moderate-to-severe cases of varicella was 55.4%. Conclusion: Altogether, these results indicate that vaccination against varicella among adolescents and adults affected the epidemiology and attenuated the disease severity of the cases. The Results from this study will provide useful information for the prevention of varicella in adolescents and adults.

While some case-control studies have showed the correlation between the hypertriglyceridemic waist (HTGW) phenotype (increased WC and hypertriglyceridemia) and cardiovascular disease (CVD) events, there are few data regarding this correlation in cohort studies, especially in Asian populations that have a higher prevalence of central obesity than other populations.

Hide Abstract
Few researchers have examined the effects of multiple risk factors of cardiovascular disease (CVD) mortality simultaneously. This study was to determine the associations of combined lifestyle and other factors with CVD mortality among the elderly (n = 3,257), in Beijing, China, through data mining of the Beijing Longitudinal Study of Aging (BLSA). BLSA is a representative cohort study from 1992 to 2009, hosted by Xuan Wu Hospital. Competing risk survival analysis was conducted to explore the association between risk factors and CVD mortality. The factors focused mainly on lifestyle, physical condition, and the model was adjusted for age and gender. There were 273 of the 1,068 recorded deaths caused by CVD among the 2010 participants. Living in a suburban area (HR = 0.614, 95% CI: 0.410-0.921) was associated with lower CVD mortality. Increasing age (66-75: HR = 1.511, 95% CI: 1.111-2.055; ? 76: HR = 1.847, 95% CI: 1.256-2.717), high blood pressure (HR = 1.407, 95% CI: 1.031-1.920), frequent consumption of meat (HR = 1.559, 95% CI: 1.079-2.254) and physical inactivity (p = 0.046) were associated with higher CVD mortality. The study provides an instructional foundation for the control and prevention of CVD in Beijing, China.

Association between ?-glutamyl transferase and metabolic syndrome: a cross-sectional study of an adult population in Beijing.
Int J Environ Res Public Health

Show Abstract
Hide Abstract
The relationship between liver enzymes and clustered components of metabolic syndrome (MetS) is explored and the predictive power of ?-glutamyl transferase (GGT) for the diagnosis of MetS in an adult population in Beijing is investigated. A total of 10,553 adults aged 20-65 years who underwent health examinations at Beijing Tongren Hospital in 2012 were enrolled in the study. Multivariate logistic regression analysis is conducted to determine the associations between the levels of various liver enzymes and clustered components of MetS. A receiver operating characteristic analysis is used to determine the optimal cut-off value of GGT for the diagnosis of MetS. A high level of GGT is found to be positively associated with clustered components of MetS in both men and women after adjusting for age, body mass index (BMI), history of alcoholic fatty liver, and the presence of taking anti-hypertensive, anti-dyslipidemic, and anti-diabetic drugs. Among all components of MetS, GGT is more predictive of triglyceride, and BMI. The area-under-the-curve values of GGT for discriminating MetS from normal metabolic status in men and women are 0.73 and 0.80, respectively. The optimal cut-off value of GGT for men is 31.50 U/L, demonstrating a sensitivity of 74.00% and specificity of 62.00%. For women, it is 19.50 U/L (sensitivity 76.00% and specificity 70.00%). GGT is therefore recommended as a useful diagnostic marker for MetS, because the test is inexpensive, highly sensitive, and frequently encountered in clinical practice.

Hide Abstract
Lung cancer is one of the most common forms of cancer resulting in over a million deaths per year worldwide. In this paper, the usage of support vector machine (SVM) classification for lung cancer is investigated, presenting a systematic quantitative evaluation against Boosting, Decision trees, k-nearest neighbor, LASSO regressions, neural networks and random forests. A large database of 5984 regions of interest (ROIs) and 488 input features (including textural features, patient characteristics, and morphological features) were used to train the classifiers and evaluate for their performance. The evaluation for classifiers performance was based on a tenfold cross validation framework, receiver operating characteristic curve (ROC), and Matthews correlation coefficient. Area under curve (AUC) of SVM, Boosting, Decision trees, k-nearest neighbor, LASSO, neural networks, random forests were 0.94, 0.86, 0.73, 0.72, 0.91, 0.92, and 0.85, respectively. It was proved that SVM classification offered significantly increased classification performance compared to the reference methods. This scheme may be used as an auxiliary tool to differentiate between benign and malignant SPNs of CT images in future.

Prevalence of metabolic syndrome is high and increasing in China. The causation of this disorder is, yet, to be fully understood. Several studies with confirmatory factor analysis have been performed to investigate the core of the disease in some races other than Chinese, and amongst the other studies, they have yielded a sound model fit. This study was to evaluate and compare two single-factor models of the underlying factor structure of metabolic syndrome in a Chinese population using confirmatory factor analysis.

Show Abstract
Hide Abstract
Using data from the Immunization Information System (IIS) and the Infectious Disease Reporting System (IDRS), we have described the epidemiology and analyzed the risk factors for breakthrough varicella in the Fengtai district of Beijing, China. From 2008 to 2011 the breakthrough varicella infection rate (BVR) was 0.65%, 0.85%, 1.08% and 1.56% respectively, thus demonstrating a distinct increasing tendency (P<0.001). We also compared the incidence of varicella-related illnesses between the breakthrough varicella cases and unvaccinated cases, and found that the severity of illness in the breakthrough cases was milder than that of unvaccinated cases. Moderate-to-severe cases (P=0.008, OR=0.676, 95% CI=0.505-0.904) were differently distributed in the breakthrough varicella cases and unvaccinated cases. In this study, we demonstrated that floating status (P=0.031, OR=1.96, 95% CI=1.06-3.62), contact history (P<0.001, OR=2.67, 95% CI=1.59-4.69), time since vaccination (P=0.006, OR=1.59, 95% CI=1.14-2.21), age at vaccination (P=0.010, OR=0.59, 95% CI=0.39-0.88) and combined vaccination (P=0.026, OR=3.99, 95% CI=1.18-13.54) were associated with the occurrence of breakthrough varicella, and among these, floating status is a novel risk factor. This study should provide useful information for the evaluation of the performance of varicella vaccination and prevention in PR China.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
