Sleep research has been dominated by high income countries (HIC). Sleep may be different in low and middle income countries (LMIC) due to cultural, demographic, geographical and health factors. We systematically reviewed the epidemiological literature reporting sleep parameters in the adult population in LMIC and meta-analyzed the prevalence of subjective poor sleep quality and sleep duration. We identified 45 publications; over 50% of which came from China and Brazil. Of the 45 identified studies, 32 contained data on sleep quality and 17 on self-reported sleep duration...

Neuromyelitis optica (NMO) is a rare autoimmune disease that affects the optic nerve and spinal cord. Most NMO patients ( > 70%) are seropositive for circulating autoantibodies against aquaporin 4 (NMO-IgG+). Here, we meta-analyze whole-genome sequences from 86 NMO cases and 460 controls with genome-wide SNP array from 129 NMO cases and 784 controls to test for association with SNPs and copy number variation (total N = 215 NMO cases, 1244 controls). We identify two independent signals in the major histocompatibility complex (MHC) region associated with NMO-IgG+, one of which may be explained by structural variation in the complement component 4 genes...

BACKGROUND: Alcohol and tobacco use are heritable phenotypes. However, only a small number of common genetic variants have been identified, and common variants account for a modest proportion of the heritability. Therefore, this study aims to investigate the role of low-frequency and rare variants in alcohol and tobacco use. METHODS: We meta-analyzed ExomeChip association results from eight discovery cohorts and included 12,466 subjects and 7432 smokers in the analysis of alcohol consumption and tobacco use, respectively...

The mortality rate of post-infarction cardiogenic shock (CS) was 80.0-90.0%. Recent studies show a significant reduction of hospital mortality to approximately 50.0%. CS is defined as systemic tissue hypoperfusion resulting from systolic and/or diastolic heart dysfunction, the main cause of which is acute myocardial infarction (AMI). The main predictors are biological markers such as troponin, CKMB and lactate. A systematic literature review and meta-analysis is performed in order to present and correlate the main literary findings on CS and its evolution with possible changes in biomarkers such as troponin, lactate and CKMB...

Despite the phenotype has been established that M2 macrophages promotes the metastasis of ESCC, question still remains as to how the M2 macrophages facilitated metastasis of ESCC cells. To begin with, immunohistochemistry was performed to detect the expression of CD163, one typical surface marker of M2 macrophages in 90 paired ESCC and its normal controls after meta-analyzing the relevant studies regarding M2 macrophages in ESCC, confirming that infiltration of M2 macrophages was significantly linked with lymph node metastasis, T classification, and inferior overall survival of ESCC...

The broader autism phenotype (BAP) is a collection of sub-diagnostic autistic traits more common in families of individuals with autism spectrum disorder (ASD) than in the general population. BAP is a latent construct that can be defined using different domains, measured using multiple instruments, and reported using different techniques. Therefore, estimates of BAP may vary greatly across studies. Our objective was to systematically review studies that reported occurrence of BAP in parents of children with ASD in order to quantify and describe heterogeneity in estimates...

Presenting information in a perceptually degraded format sometimes enhances learning outcomes. However, earlier studies in which words were presented in large or small fonts in a paradigm that also involved item-by-item judgments of learning (JOLs) consistently yielded no mnemonic benefit of small fonts. Can small font size enhance memory under hitherto unexamined conditions? A series of 11 experiments was conducted to examine systematically the effect of font size on memory for words and whether it depends on the strength of the font size manipulation, whether JOLs are solicited, the format of the test, and study time...

Meta-analysis is now an essential tool for genetic association studies, allowing them to combine large studies and greatly accelerating the pace of genetic discovery. Although the standard meta-analysis methods perform equivalently as the more cumbersome joint analysis under ideal settings, they result in substantial power loss under unbalanced settings with various case-control ratios. Here, we investigate the power loss problem by the standard meta-analysis methods for unbalanced studies, and further propose novel meta-analysis methods performing equivalently to the joint analysis under both balanced and unbalanced settings...
