Petroleum extraction and refining are major sources of various occupational exposures and of air pollution and may therefore contribute to the global cancer burden. This systematic review and meta-analysis is aimed at evaluating the cancer risk in petroleum-exposed workers and in residents living near petroleum facilities. Relevant studies were identified and retrieved through PubMed and Web of Science databases. Summary effect size (ES) and 95% confidence intervals (CI) were analysed using random effect models, and heterogeneity across studies was assessed (I2). Overall, petroleum industry work was associated with an increased risk of mesothelioma (ES = 2.09, CI: 1.58–2.76), skin melanoma (ES = 1.34, CI: 1.06–1.70 multiple myeloma (ES =1.81, CI: 1.28–2.55), and cancers of the prostate (ES = 1.13, Cl: 1.05–1.22) and urinary bladder (ES = 1.25, CI: 1.09–1.43) and a decreased risk of cancers of the esophagus, stomach, colon, rectum, and pancreas. Offshore petroleum work was associated with an increased risk of lung cancer (ES = 1.20; 95% CI: 1.03–1.39) and leukemia (ES = 1.47; 95% CI: 1.12–1.92) in stratified analysis. Residential proximity to petroleum facilities was associated with childhood leukemia (ES = 1.90, CI: 1.34–2.70). Very few studies examined specific exposures among petroleum industry workers or residents living in oil producing communities. The present review warrants further studies on specific exposure levels and pathways among petroleum-exposed workers and residents living near petroleum facilities.

Abstract Background Sarcomas are a rare and heterogeneous group of tumors originating from mesenchymal or connective tissue. They represent less than 1% of all adult cancers. The etiology and epidemiology of sarcomas remain understudied and poorly understood. The main objective of our study was to systematically assess the association between various occupational exposures and risk of sarcomas. Methods We performed a systematic literature search using the PubMed, Scopus, EMBASE and Cochrane databases to identify relevant cohort and case–control studies. A meta-analysis method was applied on the incidence and mortality outcomes where the estimate with 95% confidence interval (CI) was obtained. Results We included a total of 50 publications in our systematic review and 35 in meta-analysis. For exposures to phenoxy herbicides and chlorophenols, the pooled odds ratio (OR) for sarcoma was 1.85 (95% CI: 1.22, 2.82), based on 16 studies with 2254 participants, while the pooled standardized mortality ratio was 40.93 (95% CI 2.19, 765.90), based on 4 cohort studies with 59,289 participants. For exposure to vinyl chloride monomers the pooled risk ratios for angiosarcoma of the liver and other STS were 19.23 (95% CI 2.03, 182.46) and 2.23 (95 CI 1.55, 3.22) respectively based on 3 cohort studies with 12,816 participants. Exposure to dioxins was associated with an increased STS mortality; the pooled standardized mortality ratio was 2.56 (95% CI 1.60, 4.10) based on 4 cohort studies with 30,797 participants. Finally, woodworking occupation was associated with an increased risk of STS with the pooled OR of 2.16 (95% CI 1.39, 3.36). Conclusions Our findings suggest a positive association between higher exposure to dioxins and increased mortality from STS, between cumulative exposure to vinyl chloride monomers and increased mortality from angiosarcoma of the liver and STS, and between woodworking occupation and STS incidence. These findings were all statistically significant.

AbstractThe aims of this systematic review and meta-analysis were to describe prevalence of cardiovascular disease in gout, compare these results with non-gout controls and consider whether there were differences according to geography. PubMed, Scopus and Web of Science were systematically searched for studies reporting prevalence of any cardiovascular disease in a gout population. Studies with non-representative sampling, where a cohort had been used in another study, small sample size (< 100) and where gout could not be distinguished from other rheumatic conditions were excluded, as were reviews, editorials and comments. Where possible meta-analysis was performed using random-effect models. Twenty-six studies comprising 949,773 gout patients were included in the review. Pooled prevalence estimates were calculated for five cardiovascular diseases: myocardial infarction (2.8%; 95% confidence interval (CI)s 1.6, 5.0), heart failure (8.7%; 95% CI 2.9, 23.8), venous thromboembolism (2.1%; 95% CI 1.2, 3.4), cerebrovascular accident (4.3%; 95% CI 1.8, 9.7) and hypertension (63.9%; 95% CI 24.5, 90.6). Sixteen studies reported comparisons with non-gout controls, illustrating an increased risk in the gout group across all cardiovascular diseases. There were no identifiable reliable patterns when analysing the results by country. Cardiovascular diseases are more prevalent in patients with gout and should prompt vigilance from clinicians to the need to assess and stratify cardiovascular risk. Future research is needed to investigate the link between gout, hyperuricaemia and increased cardiovascular risk and also to establish a more thorough picture of prevalence for less common cardiovascular diseases.

Abstract Background The probability of developing invasive cutaneous malignant melanoma (CMM) is higher in women than in men up until the age of 49. Several studies investigated the association between hormonal factors and CMM. The aim of this systematic review and meta-analysis is to summarize the evidence on the association between Oral Contraceptives (OC) and the risk of CMM. Methods This review and meta-analysis follow the PRISMA guidelines. A systematic literature search was conducted on Medline and Web of Science until December 2019. Studies were eligible if reported a risk estimate for the association between OC and CMM. Heterogeneity testing was performed using Cochran's Q and I2 statistics. Publication bias was assessed by Egger's test and Begg's test. Meta-analysis was performed using random effect model. Results The results of the pooled analysis of all 32 studies showed no significant association between OC and the risk of CMM (OR 1.02; 95% CI 0.94-1.11; I2=39.32%, p = 0.013). The stratified analyses by study design found no significant association between OC and the risk of CMM neither in the 18 case-control studies (OR 1.02; 95% CI 0.87-1.21; I2=56.91%, p = 0.002) nor in the 14 cohort studies (OR 1.04; 95% CI 0.98-1.11; I2=0.00%, p = 0.557). No significant publication bias could be detected by Egger's test or Begg's test. Conclusions This meta-analysis of available literature suggests no significant association between OC and the risk of developing CMM. Further investigations are needed to evaluate the possible relationship of OC use and other hormonal factors potentially contributing to the increased risk of CMM in women during their reproductive years. Key messages Oral contraceptives (OC) do not significantly contribute to the risk of Cutaneous Malignant Melanoma (CMM). Further studies are needed to investigate the potential role of other hormonal factors in the increased probability of developing CMM in women during their reproductive years.

Abstract Background Long-term anticoagulation in patients with atrial fibrillation (AF) imposes a careful balance between the thromboembolic and hemorrhagic risks. An association between cerebral microbleeds (CMBs) and an increased risk of intracranial hemorrhage (ICH) has already been described; however, conflicting evidence exist on the association with ischemic stroke (IS). Although CMBs are often observed in AF patients, the actual prevalence and the magnitude of the risk of adverse events in patients with CMBs is unclear. Purpose We aimed to estimate the pooled prevalence of CMBs in patients with AF through a systematic review and meta-analysis of the literature. Additionally, we evaluated the risk of ICH and IS according to the presence and burden of CMBs. Methods We perform a systematic search on PubMed and EMBASE from inception to 6th March 2021. We included all studies reporting the prevalence of CMBs, the incidence of ICH and/or IS in AF by presence of CMBs. Pooled prevalence and odds ratios (OR), along with their 95% Confidence Intervals (CI), were computed using random-effect models; we also calculated 95% Prediction Intervals (PI) for each outcome investigated. Additionally, we performed subgroup analyses according to the number and localization of CMBs. Results We retrieved 562 records from the literature search, and 17 studies were finally included. Pooled prevalence of CMBs in AF population was 28.3% (95% CI: 23.8%-33.4%; 95% PI: 12.2%-52.9%, Figure 1). Individuals with CMBs showed a higher risk of both ICH (OR: 3.04, 95% CI: 1.83–5.06) and IS (OR: 1.78, 95% CI: 1.26–2.49). Moreover, patients with more than 5 CMBs, as well as patients with both lobar and mixed CMBs, showed a higher risk of ICH. Conclusions CMBs were found in 28.3% of AF patients, with 95% PIs indicating a potentially higher prevalence. Moreover, CMBs were associated with an increased risk of both ICH and IS, with the effect potentially modulated by their number and localization. CMBs may represent an important and often overlooked risk factor for adverse outcomes in patients with AF. FUNDunding Acknowledgement Type of funding sources: None.

ABSTRACT BACKGROUND: The role of -251A>T polymorphism in the anti-inflammatory cytokine interleukin-8 (IL-8) gene in gastric cancer was intensively evaluated, but the results of these studies were inconsistent. OBJECTIVE: Therefore, we performed a meta-analysis to provide a comprehensive data on the association of IL-8 -251T>A polymorphism with gastric cancer. METHODS: All eligible studies were identified in PubMed, Web of Science, EMBASE, Wanfang and CNKI databases before September 01, 2019. The pooled odds ratios (ORs) with 95% confidence intervals (CIs) were derived from a fixed effect or random effect model. RESULTS: A total of 33 case-control studies with 6,192 cases and 9,567 controls were selected. Overall, pooled data showed that IL-8 -251T>A polymorphism was significantly associated with an increased risk of gastric cancer under all five genetic models, i.e., allele (A vs T: OR=1.189, 95% CI 1.027-1.378, P=0.021), homozygote (AA vs TT: OR=1.307, 95% CI 1.111-1.536, P=0.001), heterozygote (AT vs TT: OR=1.188, 95% CI 1.061-1.330, P=0.003), dominant (AA+AT vs TT: OR=1.337, 95% CI 1.115-1.602, P=0.002) and recessive (AA vs AT+TT: OR=1.241, 95% CI 1.045-1.474, P=0.014). The stratified analysis by ethnicity revealed an increased risk of gastric cancer in Asians and mixed populations, but not in Caucasians. Moreover, stratified by country found a significant association in Chinese, Korean and Brazilian, but not among Japanese. CONCLUSION: This meta-analysis suggests that the IL-8 -251T>A polymorphism is associated with an increased risk of gastric cancer, especially by ethnicity (Asian and mixed populations) and country (Chinese, Korean and Brazilian).

Background: Natalizumab (NTZ) is sometimes discontinued in patients with multiple sclerosis, mainly due to concerns about the risk of progressive multifocal leukoencephalopathy. However, NTZ interruption may result in recrudescence of disease activity. Objective: The objective of this study was to summarize the available evidence about NTZ discontinuation and to identify which patients will experience post-NTZ disease reactivation through meta-analysis of existing literature data. Methods: PubMed was searched for articles reporting the effects of NTZ withdrawal in adult patients (⩾18 years) with relapsing–remitting multiple sclerosis (RRMS). Definition of disease activity following NTZ discontinuation, proportion of patients who experienced post-NTZ disease reactivation, and timing to NTZ discontinuation to disease reactivation were systematically reviewed. A generic inverse variance with random effect was used to calculate the weighted effect of patients’ clinical characteristics on the risk of post-NTZ disease reactivation, defined as the occurrence of at least one relapse. Results: The original search identified 205 publications. Thirty-five articles were included in the systematic review. We found a high level of heterogeneity across studies in terms of sample size (10 to 1866 patients), baseline patient characteristics, follow up (1–24 months), outcome measures (clinical and/or radiological), and definition of post-NTZ disease reactivation or rebound. Clinical relapses were observed in 9–80% of patients and peaked at 4–7 months, whereas radiological disease activity was observed in 7–87% of patients starting at 6 weeks following NTZ discontinuation. The meta-analysis of six articles, yielding a total of 1183 patients, revealed that younger age, higher number of relapses and gadolinium-enhanced lesions before treatment start, and fewer NTZ infusions were associated with increased risk for post-NTZ disease reactivation ( p ⩽ 0.05). Conclusions: Results from the present review and meta-analysis can help to profile patients who are at greater risk of post-NTZ disease reactivation. However, potential reporting bias and variability in selected studies should be taken into account when interpreting our data.

AbstractBackgroundHypertension is a common public health problem worldwide and is a well-known risk factor for increased risk of cardiovascular diseases, contributing to high morbidity and mortality. However, there is no systematic review and meta-analysis that has been done in a multi-ethnic population like Malaysia. This systematic review aims to determine the trend in prevalence, awareness and control of hypertension in Malaysia.MethodsSystematic searches were conducted in PubMed, Scopus, Ovid, Cumulative Index to Nursing and Allied Health Literature, Malaysian Medical Repository and Malaysia Citation Index published between 1980 and 2017. All original articles in English were included. Studies included were those on adults aged 18 years and above. Studies of prevalence in children and adolescents and pregnancy related hypertension were excluded. Two authors independently reviewed the studies, carried out data extraction and performed quality assessment. Heterogeneity between studies and publication bias was assessed and effect size was pooled by the random effect model.ResultsFifty-six studies with a total of 241,796 subjects were included. The prevalence of hypertension throughout Malaysia varied (I2= 99.3%). The overall pooled prevalence of hypertension over the past 4 decades was 28.2% in adults aged 18 years and older (95% CI: 26.1 – 33.3) and the prevalence in those 30 years and older was 40.0% (95% CI: 35.3-44.8).For subgroup analysis, the prevalence of hypertension in male aged 18 and above was 31.4% (95% CI: 26.5 - 36.2) and 27.8% in female (95% CI: 20.7 – 34.9). The prevalence of hypertension among the ethnic groups aged 18 years and above were 37.3% in Malays (95% CI: 32.9 – 41.7); 36.4% in Chinese (95% CI 31.6 - 41.2) and 34.8% in Indians (95% CI: 31.2-38.4). The prevalence of hypertension was the lowest in the 1980s (16.2%, 95% CI: 13.4-19.0%), increases up to 36.8% in the 1990s (95% CI: 6.1-67.5), then came down to 28.7% (95% CI: 21.7-35.8) in the 2000s and 29.2% (95% CI: 24.0-34.4) in the 2010s. The prevalence of awareness was 38.7% (95% CI: 31.7 – 45.8) whereas the control of hypertension of those on treatment was 33.3% (95% CI: 28.4 – 38.2).ConclusionThree in 10 adults aged 18 years old and above have hypertension, whereas four in 10 adults aged 30 years old and above have hypertension. Four out of 10 are aware of their hypertension status and only one-third of them who were under treatment achieved control of their hypertension. Concerted efforts by policymakers and healthcare professionals to improve the awareness and control of hypertension should be of high priority.

Abstract Objective Metabolic signatures have emerged as valuable signaling molecules in the biochemical process of type 2 diabetes (T2D). To summarize and identify metabolic biomarkers in T2D, we performed a systematic review and meta-analysis of the associations between metabolites and T2D using high-throughput metabolomics techniques. Methods We searched relevant studies from MEDLINE (PubMed), Embase, Web of Science, and Cochrane Library as well as Chinese databases (Wanfang, Vip, and CNKI) inception through 31 December 2018. Meta-analysis was conducted using STATA 14.0 under random effect. Besides, bioinformatic analysis was performed to explore molecule mechanism by MetaboAnalyst and R 3.5.2. Results Finally, 46 articles were included in this review on metabolites involved amino acids, acylcarnitines, lipids, carbohydrates, organic acids, and others. Results of meta-analysis in prospective studies indicated that isoleucine, leucine, valine, tyrosine, phenylalanine, glutamate, alanine, valerylcarnitine (C5), palmitoylcarnitine (C16), palmitic acid, and linoleic acid were associated with higher T2D risk. Conversely, serine, glutamine, and lysophosphatidylcholine C18:2 decreased risk of T2D. Arginine and glycine increased risk of T2D in the Western countries subgroup, and betaine was negatively correlated with T2D in nested case-control subgroup. In addition, slight improvements in T2D prediction beyond traditional risk factors were observed when adding these metabolites in predictive analysis. Pathway analysis identified 17 metabolic pathways may alter in the process of T2D and metabolite-related genes were also enriched in functions and pathways associated with T2D. Conclusions Several metabolites and metabolic pathways associated with T2D have been identified, which provide valuable biomarkers and novel targets for prevention and drug therapy.

Abstract Background Patients with Crohn’s disease (CD) and ulcerative colitis (UC) are at increased risk of developing intestinal cancer compared with the background population. However, less is known about the risk of extra-intestinal cancers (EICs). A previous meta-analysis did not find an increased overall risk of EICs but was limited by the scarcity of available studies and the short length of follow-up in those cohorts. The aim of this study was to conduct a systematic review and meta-analysis of population-based cohorts assessing the risk of EICs in inflammatory bowel disease (IBD) patients. Methods A systematic literature search was carried out. Only population-based studies reporting on the prevalence or incidence of EICs were included. All studies were screened (603), and included studies were quality assessed by two investigators (BL, MZ). Studies eligible for meta-analysis were pooled for events, expected events or events in a control-population, and the length of follow-up in patient-years. A meta-analysis of the overall and site-specific risk of EICs and a stratified analysis of the cohorts (according to whether there were most patients followed before or after the year 2000) were conducted. Results In total, 36 studies were included in the systematic review and 14 studies were included in the meta-analysis. The majority of the studies reporting on the overall risk of EICs in their respective cohort were inconclusive due to lack of power. In the meta-analysis, the overall risk of EICs was found to be increased in both CD (IRR: 1.45 [1.26, 1.67]) and UC (IRR: 1.15 [1.02, 1.31]) patients (Figures 1 and 2). The stratified analysis showed a significant increased risk of EICs among CD patients both before (IRR: 1.58 [1.09, 2.28]) and after (IRR: 1.47 [1.28, 1.69]) the year 2000, while no increased risk was found among UC patients. Assessing site-specific EICs, both CD and UC patients demonstrated an increased risk of skin and hepatobiliary malignancies. Furthermore, CD demonstrated an increased risk of haematological and lung malignancies (Figures 3 and 4). Conclusion In conclusion, this systematic review and meta-analysis demonstrated that IBD patients, both CD and UC patients, are at an increased risk of developing EICs; both overall and at specific sites. The transition of the millennium did not increase the risk of EICs in CD or UC patients. However, more studies with longer follow-up are needed to assess the true risk of EICs posed by IBD.

Introduction: Studies have shown that the use of antiplatelet and anticoagulant increases the risk of cardiac implantable electronic device (CIED) infection following the implantation. However, results were contradicting. In this study, we performed a systematic review and meta-analysis to explore the effect of antiplatelets and anticoagulants and the risk of CIED infection following the implantation. Methods: We searched the databases of MEDLINE and EMBASE from inception to March 2020. Included studies were published studies of patients undergoing CIED implantations which reported effect size of the use of either antiplatelet or anticoagulant, or both, on the risk of CIED infections. CIED infection was defined as either device-related local or systemic infection. Data from each study were combined using the random-effects, generic inverse variance method of Der Simonian and Laird to calculate effect size and 95% confidence intervals (CI). Results: Fifteen studies from 2008-2019 involving a total of 72,028 patients were included. In random-effect model, we found that the use of antiplatelet was not associated with an increased risk of CIED infections (risk ratio (RR) =1.13, 95% CI: 0.89-1.44, p=0.314, I 2 =51.3%), while the use of anticoagulant was associated with increased risk of CIED infections (RR =1.50, 95%CI: 1.02-2.21, p=0.038, I 2 =75%). There was no publication bias observed in the funnel plot as well as no small-study effect observed in Egger’s test. Conclusions: Our meta-analysis demonstrated that the use of anticoagulant significantly increases the risk of CIED infection following the implantation by up to 1.50-fold, however, this effect was not observed with antiplatelet use. Our study suggested that patients on anticoagulation considering CIED implantations should proceed with caution.
