A meta-analysis of genome-wide association studies identifies multiple longevity genes.
Deelen J, et al. Nat Commun 2019. PMID 31413261 Free PMC article.
Here, we perform two meta-analyses of GWA studies of a rigorous longevity phenotype definition including 11,262/3484 cases surviving at or beyond the age corresponding to the 90th/99th survival percentile, respectively, and 25,483 controls whose age at death or at last contact was at or below the age corresponding to the 60th survival percentile. ...Gene-level association analysis reveals a role for tissue-specific expression of multiple genes in longevity. Finally, genetic correlation of the longevity GWA results with that of several disease-related phenotypes points to a shared genetic architecture between health and longevity....

A meta-analysis of flow effects and the perception of time.
Hancock PA, et al. Acta Psychol (Amst) 2019. PMID 31279183
While a number of other factors necessarily contribute to this overall experience of flow, subjective time perception is of particular quantitative interest and thus serves as the focus of the present meta-analysis. ...The results of this meta-analysis also serve to inform the process of further model development that can more accurately quantify and predict temporal perception as one metric of flow....

Vitamin D supplementation to prevent acute respiratory infections: individual participant data meta-analysis.
Martineau AR, et al. Health Technol Assess 2019. PMID 30675873 Free PMC article.
Individual participant data (IPD) meta-analysis has the potential to identify factors that may explain this heterogeneity. OBJECTIVES: To assess the overall effect of vitamin D supplementation on the risk of acute respiratory infections (ARIs) and to identify factors modifying this effect. ...Subgroup analysis revealed that protective effects were seen in individuals receiving daily or weekly vitamin D without additional bolus doses (aOR 0.81, 95% CI 0.72 to 0.91), but not in those receiving one or more bolus doses (aOR 0.97, 95% CI 0.86 to 1.10; p = 0.05). ...

Efficacy and safety of dupilumab for the treatment of uncontrolled asthma: a meta-analysis of randomized clinical trials.
Xiong XF, et al. Respir Res 2019. PMID 31151443 Free PMC article.
We therefore conducted this meta-analysis to evaluate the overall efficacy and safety of dupilumab for the treatment of uncontrolled asthma. ...Pooled analysis showed significant improvements in the first-second forced expiratory volume (FEV(1)) (SMD = 4.29, 95% CI: 2.78-5.81) and Asthma Quality of Life Questionnaire scores (SMD = 4.39, 95% CI: 1.44-7.34). ...

Association of rosacea with inflammatory bowel disease: A MOOSE-compliant meta-analysis.
Wang FY and Chi CC. Medicine (Baltimore) 2019. PMID 31593075 Free PMC article.
Thus, our objective is to conduct a meta-analysis on the association of rosacea with IBD.We conduct a meta-analysis and searched MEDLINE, CENTRAL, and Embase databases for case-controlled and cohort studies that assessed the association of rosacea with IBD from inception to July 2nd, 2018. ...We performed random-effects model meta-analysis to obtain the pooled risk estimates for Crohn disease (CD) and ulcerative colitis (UC) in patients with rosacea.We included three case-control and three cohort studies. ...

Meta-Analysis of SNP-Environment Interaction with Heterogeneity.
Jin Q and Shi G. Hum Hered 2019. PMID 31865312
In this work, we propose a meta-analysis of testing single nucleotide polymorphism (SNP)-environment interaction in the presence of genetic heterogeneity. We introduced the random effects of the SNP and SNP-environment interaction under test into a meta-regression model to account for heterogeneity. ...

The association between vitamin D deficiency and community-acquired pneumonia: A meta-analysis of observational studies.
Zhou YF, et al. Medicine (Baltimore) 2019. PMID 31567995 Free PMC article.
This meta-analysis was performed following the guidelines of Meta-analysis of Observational Studies in Epidemiology. The association between vitamin D levels and CAP were measured as odds ratio (OR) and weighted mean difference (WMD). ...Sensitivity analysis showed that exclusion of any single study did not materially alter the overall combined effect.The evidence from this meta-analysis indicates an association between vitamin D deficiency and an increased risk of CAP patients. ...
