The Relationship

The relationship between subclinical thyroid dysfunction and uric acid was not well established. This study aimed to determine if subclinical thyroid dysfunction is associated with hyperuricemia risk and to evaluate the levels of uric acid in patients with different forms of subclinical thyroid dysfunction. A systematic search was conducted in 4 databases to obtain relevant studies on subclinical thyroid dysfunction (subclinical hyperthyroidism and subclinical hypothyroidism) and uric acid. The standardized mean difference (SMD) or odds ratio (OR) and 95% confidence interval (95% CI) were used for evaluation, and the sensitivity analysis was conducted. Publication bias was estimated by funnel plot, Egger’s test, and Begg’s test. A total of 73 studies were included in this meta-analysis. The results demonstrated that serum levels of uric acid in patients with subclinical hypothyroidism were significantly higher than those of controls and patients with subclinical hyperthyroidism. Patients with subclinical thyroid dysfunction had a higher prevalence of hyperuricemia compared with normal clinical thyroid function. Subclinical thyroid dysfunction was associated with the prevalence of hyperuricemia. Different types of subclinical thyroid dysfunction had varied effects on serum levels of uric acid.

Chronic Autoimmune Disease

Introduction Systemic lupus erythematosus (SLE) is a chronic autoimmune disease, the pathogenesis of which remains elusive. The deficiency or excess of thyroid hormone is defined as thyroid dysfunction, including (subclinical) hypothyroidism and (subclinical) hyperthyroidism. Autoimmune factors are likely to be relevant to the development of SLE and thyroid dysfunction. Recently, many studies have indicated that the prevalence of thyroid dysfunction is higher in SLE patients than in the general population. The objective of our study was to perform a systematic review and meta-analysis to find out the relationship between SLE and thyroid dysfunction. Methods Literature databases were searched, including PubMed, Embase, Web of science, Cochrane, CNKI, CHINESE WANFANG, China Science and Technology Database (VIP). Studies comparing presence of thyroid dysfunction in SLE patients to healthy controls were extracted. All the statistical analyses were performed with STATA 12.0 software. Results Ten studies with 10,500 SLE patients and 44,170 healthy controls were included in this study. The meta-analysis results showed that the prevalence of (subclinical) hypothyroidism in SLE patients was higher than in the healthy controls (hypothyroidism: OR = 2.93, 95% CI = 1.81–4.75; subclinical hypothyroidism: OR = 5.67, 95% CI = 3.50–9.18). No statistical difference of (subclinical) hyperthyroidism was found between SLE patients and controls. Conclusion Our meta-analysis suggests that SLE is significantly associated with increased risk of (subclinical) hypothyroidism, but it has little influence on (subclinical) hyperthyroidism.

Abstract Funding Acknowledgements Type of funding sources: Other. Main funding source(s): This project was supported by the MRes programme in the Institute of Life Course and Medical Sciences at The University of Liverpool. Thyroid hormones can act directly and indirectly on the cardiovascular system and studies have demonstrated associations between overt and subclinical thyroid dysfunction and adverse cardiovascular outcomes including heart failure, myocardial infarction, and coronary heart disease. The aim of this study was to assess the association between subclinical thyroid dysfunction and atrial fibrillation (AF).  The protocol was registered on PROSPERO (CRD42020221565). MEDLINE and Scopus were searched from inception to 13th November 2020 for studies investigating subclinical thyroid dysfunction and incident AF. Risk of bias was assessed using the Risk of Bias Assessment Tool (RoBANS). The quality of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) tool. Subgroup analysis was performed for post-operative and non-post-operative AF. 5413 records were identified. Nine cohort studies were suitable for inclusion in the systematic review, of which seven studies were included in the meta-analysis. The meta-analysis comprised 595,058 patients. Subclinical hyperthyroidism was associated with a 99% increase in the risk of incident AF (Risk ratio (RR): 1.99; 95% confidence intervals (CI); 1.43 to 2.77; p < 0.0001; I² = 67%). Subclinical hypothyroidism was also associated with a greater risk of AF (RR: 1.24; 95% CI; 1.05 to 1.47; p = 0.01; I² = 65%). Subgroup analysis demonstrated a 76% increase in the risk of post-operative AF in patients with subclinical hypothyroidism compared to euthyroid post-operative patients (RR: 1.76; 95% CI; 1.36 to 2.28; p < 0.0001; I² = 0%). Six studies were rated as low risk of bias and three as medium risk of bias according to the RoBANS tool. The quality of evidence for AF in subclinical hyper- and hypothyroid patients was low. Subclinical hyperthyroidism and subclinical hypothyroidism were associated with a higher risk of incident AF and post-operative AF, respectively. The quality of the current evidence is low and ideally a randomised controlled trial should be conducted to confirm these associations and assess impacts of treatments. Abstract Figure.

Background. Evidence on the association between subclinical thyroid dysfunction and the risk of cardiovascular outcomes are conflicting. Methods and Results. PubMed, EMbase, Web of Science, Cochrane Library, and China Biology Medicine (CBM) databases were searched from inception to July 10, 2016. A total of 16 studies were included for meta-analysis. We found that subclinical hypothyroidism was not correlated with coronary heart disease (CHD) (RR = 1.17; 95% CI, 0.91–1.52), total mortality (RR = 1.02; 95% CI, 0.93–1.13), cardiovascular mortality (RR = 1.06; 95% CI, 0.77–1.45), heart failure (RR = 1.17; 95% CI, 0.87–1.57), and atrial fibrillation (RR = 1.05; 95% CI, 0.91–1.21), except CHD mortality (RR = 1.37; 95% CI, 1.03–1.84). Subgroup analysis indicated a higher estimation risk in CHD (RR = 1.54; 95% CI, 1.00–2.39), cardiovascular mortality (RR = 2.14; 95% CI, 1.43–3.22), and CHD mortality (RR = 1.54; 95% CI, 1.11–2.15) among participants < 65 years. Furthermore, subclinical hyperthyroidism was found to be associated with CHD (RR = 1.20; 95% CI, 1.02–1.42), total mortality (RR = 1.27; 95% CI, 1.07–1.51), and CHD mortality (RR = 1.45; 95% CI, 1.12–1.86). Conclusions. Subclinical hypothyroidism is likely associated with an increased risk of CHD mortality, and subclinical hyperthyroidism is likely associated with increased risk of CHD, CHD mortality, and total mortality.

AbstractElevated serum uric acid (SUA) levels may increase the risk of prehypertension. However, the findings from these studies remain conflicting. The objective of this study was to determine the relationship between SUA levels and risk of prehypertension by conducting a meta-analysis. We conducted a comprehensive literature search of PubMed, Embase, China National Knowledge Infrastructure, VIP, and the Wangfang database without language restrictions through May 2015. Observational studies assessing the relationship between SUA levels and prevalence of prehypertension were included. Pooled adjust odds ratio (OR) and corresponding 95% confidence intervals (CI) of prehypertension were calculated for the highest vs. lowest SUA levels. Prehypertension was defined as systolic blood pressure (BP) ranging from 120 to 139 mmHg or diastolic BP ranging from 80 to 89 mmHg. Eight cross-sectional studies with a total of 21,832 prehypertensive individuals were included. Meta-analysis showed that elevated SUA levels were associated with increased risk of prehypertension (OR: 1.84; 95% CI: 1.42–2.38) comparing the highest vs. lowest level of SUA levels. Subgroup analyses showed that elevated SUA levels significantly increased the risk of prehypertension among men (OR: 1.60; 95% CI: 1.12–2.21) and women (OR: 1.59; 95% CI: 1.17–2.16). Elevated SUA levels are positively associated with the risk of prehypertension in the general population. However, more well-designed longitudinal studies are needed before a definitive conclusion can be drawn due to the cross-sectional studies included are susceptible to bias.

AbstractThe association between subclinical hypothyroidism (SCH) and polycystic ovary syndrome (PCOS) has been shown in many studies. These findings are still controversial, however. It is unclear whether the co-incidence of subclinical hypothyroidism and polycystic ovary syndrome will affect the severity of metabolism. Therefore, we performed this meta-analysis to investigate the association. A comprehensive search strategy was developed to obtain all relevant studies published in PubMed, EMBASE, Cochrane Library, and Chinese Academic Journal Full-text Database (CNKI) up to 31 December 2020. We adopted the standardized mean difference (SMD) with 95% confidence intervals (CI) for evaluation, and sensitivity analysis was performed. Publication bias was analyzed and represented by a funnel plot, and funnel plot symmetry was assessed with Egger’s test. Twenty-seven studies with 4821 participants (1300 PCOS patients with SCH, 3521 PCOS patients without SCH) were included in the present meta-analysis,among which 71.31% chinese patients out of the total. The results showed that PCOS patients with SCH had higher levels of HOMA-IR, TG, TC, LDL, FBG, FCP, PRL and lower levels of HDL, LH and T. It also recognized the limitation of the lack of a consistent definition of hypothyroidism in the 27 studies included. The results of this study indicated that SCH may aggravate lipid and glucose metabolism in patients with PCOS.

BackgroundTheory of mind (ToM) dysfunction is prominent in a number of psychiatric disorders, in particular, autism and schizophrenia, and can play a significant role in poor functioning. There is now emerging evidence suggesting that ToM abilities are also impaired in bipolar disorder (BP); however, the relationship between ToM deficits and mood state is not clear.MethodWe conducted a meta-analysis of ToM studies in BP. Thirty-four studies comparing 1214 patients with BP and 1097 healthy controls were included. BP groups included remitted (18 samples, 545 BP patients), subsyndromal (12 samples, 510 BP patients), and acute (manic and/or depressed) (10 samples, 159 BP patients) patients.ResultsToM performance was significantly impaired in BP compared to controls. This impairment was evident across different types of ToM tasks (including affective/cognitive and verbal/visual) and was also evident in strictly euthymic patients with BP (d = 0.50). There were no significant differences between remitted and subsyndromal samples. However, ToM deficit was significantly more severe during acute episodes (d = 1.23). ToM impairment was significantly associated with neurocognitive and particularly with manic symptoms.ConclusionSignificant but modest sized ToM dysfunction is evident in remitted and subsyndromal BP. Acute episodes are associated with more robust ToM deficits. Exacerbation of ToM deficits may contribute to the more significant interpersonal problems observed in patients with acute or subsyndromal manic symptoms. There is a need for longitudinal studies comparing the developmental trajectory of ToM deficits across the course of the illness.

Purpose Relationship learning is viewed as an important factor in enhancing competitiveness and an important determinant of profitability in relationships. Prior studies have acknowledged the positive effects of interorganizational learning on performance, but the performance measures applied have varied. The purpose of this study is to examine the relationship between interorganizational learning and different types of performance. The paper also goes beyond direct effects by investigating the moderating effects of different research designs. Design/methodology/approach This paper applies a meta-analytic approach to systematically analyze 21 independent studies (N = 4,618) to reveal the relationship between interorganizational learning and performance. Findings The findings indicate that interorganizational learning is an important predictor of performance, and that the effects of interorganizational learning on performance differ in magnitude under different research conditions. Research limitations/implications The paper focuses on interorganizational learning, and during the data collection, some related topics were excluded from the data search to retain the focus on learning. Practical implications The study evinces the breadth of the field of interorganizational learning and how different research designs affect research results. Moreover, this meta-analysis indicates the need for greater clarity when defining the concepts used in studies and for definitions of the concepts applied in the field of interorganizational learning to be unified. Originality/value This study is the first to meta-analytically synthesize literature on interorganizational learning. It also illuminates new perspectives for future studies within this field.

Background: Diabetes mellitus is a very common endocrinal disorders and incidence of thyroid dysfunction also rising in India and world over. Thyroid hormones directly control insulin secretion and insulin clearance. Diabetes also may affect the thyroid function to variable extent first at the level of hypothalamic control of TSH release and second at peripheral tissue by converting T4 to T3. Aims and Objectives: The present study was carried out aiming to evaluate thyroid dysfunction among type 2 diabetes mellitus patients. Material and Methods: Study included total 80 subjects. Thyroid dysfunction was evaluated by investigating the subjects for Total tri-iodo-thyronine (T3), Total thyroxine (T4) and thyroid stimulating hormone (TSH). Plasma glucose was estimated by- GOD-POD method and Thyroid profile was estimated by- CLIA (chemiluminescence immunoassay) system. Statistical analysis was performed using software statistical package for social sciences (SPSS) version 20, unpaired T test, Pearson’s correlation. Results: In type 2 diabetic patients the prevalence of hypothyroidism and subclinical hypothyroidism was found to be 4(10.00%) and 6(15.00%) respectively, while the prevalence of subclinical hyperthyroidism and hyperthyroidism was found to be 0(0.0%) and 1(2.5%) respectively. In non diabetic healthy subjects the prevalence of hypothyroidism and subclinical hypothyroidism was found to be 1(2.5%) and 3(7.5%) respectively while the prevalence of subclinical hyperthyroidism and hyperthyroidism was found to be 0(0.0%) and 0(0.0%) respectively. Conclusion: The prevalence of thyroid dysfunction was found to be higher in type 2 diabetes mellitus subjects as compared to non-diabetic subjects.
