The Relationship

Purpose – The purpose of this paper is to investigate the serially mediating mechanisms of organisational justice, organisational trust, and employee reactions in the relationship between transformational leadership and organisational performance. Design/methodology/approach – The study is based on a national sample of 133 organisations from the public and private sectors in Greece and on data obtained from 1,250 employees at three hierarchical positions. The statistical method employed is structural equation modelling. Findings – The findings of the study suggest that responsive and supportive transformational leadership behaviour have a positive impact on organisational growth. Additionally, this impact is mediated by organisational procedural justice, organisational trust integrity and dependability, and organisational commitment. Research limitations/implications – The study does not allow for dynamic causal inferences because the data were collected using a questionnaire at a single point in time. Furthermore, the findings of the study may not generalise across borders, because the study was applied in the Greek context, which is experiencing a severe economic and financial crisis. Practical implications – The major message of the study to decision makers and practitioners is that leaders should work at fostering organisational commitment by improving perceptions of fairness and trust, consistent with the context where the organisation is activated. Originality/value – There is hardly any research that has been conducted to examine the serially mediating relationships of justice, trust, and employee reactions using multi-dimensional constructs in investigating the relationship between transformational leadership and organisational performance.

Susceptible Gene

Many studies have established that T-lymphocyte antigen-4 (CTLA4) is a susceptible gene for Graves’ disease (GD). Also many studies showed the association between the CTLA4 exon-1 49A/G polymorphism and the risk of developing Graves’ ophthalmopathy (GO) in GD patients. But those results were inconsistent. In recent years many new studies were published which helped to shed light on the relationship of CTLA4 SNP49 with GO. So we performed the meta-analysis to explore the association between the SNP49 and GO susceptibility in GD patients. Studies up to February 29, 2012, were searched by using PubMed. The odds ratio was used to evaluate the strength of the association. Altogether 12 case-control studies involving 2,505 participants were included in the meta-analysis. Results showed that the G allele was related to the increased risk of GO compared with the A allele under allelic genetic model (OR = 1.14, 95% CI: 1.14–1.72,P=0.001) in European subgroup. No publication bias was detected. Our results showed that the SNP49 polymorphism of CTLA4 gene was related to increased risk of GO.

BackgroundThere is no consensus on the effects that low birth weight, premature birth and intrauterine growth have on later depression.AimsTo review systematically the evidence on the relationship of low birth weight, smallness for gestational age (SGA) and premature birth with adult depression.MethodWe searched the literature for original studies assessing the effect of low birth weight, premature birth and SGA on adult depression. Separate meta-analyses were carried out for each exposure using random and fixed effects models. We evaluated the contribution of methodological covariates to heterogeneity using meta-regression.ResultsWe identified 14 studies evaluating low birth weight, 9 premature birth and 4 SGA. Low birth weight increased the odds of depression (OR = 1.39, 95% CI 1.21–1.60). Premature birth and SGA were not associated with depression, but publication bias might have underestimated the effect of the former and only four studies evaluated SGA.ConclusionsLow birth weight was associated with depression. Future studies evaluating premature birth and SGA are needed.

Aim: The aim of this study was to assess the association between PEAR1 polymorphisms and ischemic clinical outcomes. Materials & methods: We searched the electronic database for articles on the relationship of PEAR1 SNPs and ischemic events in patients with coronary artery disease (CAD) up to October 2020. Results: A total of 9914 patients with CAD from six studies focusing on 12 SNPs of PEAR1 were included in this study. The A allele of rs12041331 were associated with ischemic events (odds ratio: 1.40; 95% CI: 1.04–1.88; p = 0.03). The AA homozygotes of rs2768759 was related to a higher risk of ischemic events than carriers of the C allele (odds ratio: 2.08; 95% CI: 1.09–3.97; p = 0.03). Conclusion: PEAR1 rs12041331 and rs2768759 are significantly associated with ischemic events in patients with CAD.

Until now, the relationship of obstructive sleep apnoea (OSA) with diabetic retinopathy (DR) was controversial. This meta-analysis was performed to obtain definitive conclusion on this topic. Relevant articles were searched on databases of Pubmed, Google Scholar, and Chinese National Knowledge Infrastructure (CNKI). The articles were selected according to inclusion and exclusion criteria. Odds ratio (OR) with 95% confidence interval (CI) was used to evaluate the relationship of OSA with risk of DR.I2andPvalue were used to assess the presence of heterogeneity.I2≥ 50% orP<0.05indicated significant heterogeneity. Sensitivity analysis was performed to evaluate the robustness of pooled results. Begg’s funnel plot and Egger’s regression analysis were adopted to assess publication bias. 6 eligible studies were selected in the present meta-analysis. The pooled results indicated that OSA was significantly associated with increased risk of DR (OR = 2.01, 95% CI = 1.49–2.72). Subgroup analysis based on type of diabetes mellitus suggested that OSA was related to DR in both Type 1 and Type 2 diabetes mellitus. Sensitivity analysis demonstrated that pooled results were robust. No significant publication bias was observed (P=0.128). The results indicate that OSA is related to increased risk of DR.

Abstract Background When lowlanders rapidly ascend to altitudes > 2500 m, they may develop acute mountain sickness (AMS). The individual susceptibility, ascending velocity, time spent at altitude, activity levels and altitude reached are considered risk factors for AMS. However, it is not clear whether sex is a risk factor. The results have been inconclusive. We conducted a meta-analysis to test whether there were sex-based differences in the prevalence of AMS using Lake Louise Scoring System. Methods Systematic searches were performed in August 2019 in EMBASE, PubMed, and Web of Science for prospective studies with AMS data for men and women. The titles and abstracts were independently checked in the primary screening step, and the selected full-text articles were independently assessed in the secondary screening step by the two authors (YPH and JLW) based on pre-defined inclusion criteria. The meta-analysis was performed using by the STATA 14.1 software program. A random-effects model was employed. Results Eighteen eligible prospective studies were included. A total of 7669 participants (2639 [34.4%] women) were tested. The results showed that there was a statistically significant higher prevalence rate of AMS in women than in men (RR = 1.24, 95%CI 1.09–1.41), regardless of age or race. Howerver, the heterogeneity was significant in the analysis (Tau2 = 0.0403, Chi2 = 50.15, df = 17; I2 = 66.1%, P = 0.000), it was main caused by different numbers of subjects among the studies (coefficient = − 2.17, P = 0.049). Besides, the results showed that there was no evidence of significant publication bias in the combined studies on the basis of Egger’s test (bias coefficient = 1.48, P = 0.052) and Begg’s test (P = 0.130). Conclusions According to this study, the statistically significant finding emerging from this study was that women have a higher prevalence of AMS. However, the authors could not exclude studies where patients were on acetazolamide. Our analysis provided a direction for future studies of the relationship of sex and the risk of AMS, such as the pathological mechanism and prevention research.
