ObjectiveThis meta-analysis assessed the associations of myocardial fibrosis detected by late gadolinium-enhanced (LGE)-MRI with the risk of major adverse cardiac and cerebrovascular events (MACCEs) and major adverse cardiac events (MACEs) in patients with diabetes.DesignSystematic review and meta-analysis reported in accordance with the guidelines of the Meta-analysis of Observational Studies in Epidemiology statement.Data sourcesWe searched the Medline, Embase and Cochrane by Ovid databases for studies published up to 27 August 2021.Eligibility criteriaProspective or respective cohort studies were included if they reported the HR and 95% CIs for MACCEs/MACEs in patients with either type 1 or 2 diabetes and LGE-MRI-detected myocardial fibrosis compared with patients without LGE-MRI-detected myocardial fibrosis and if the articles were published in the English language.Data extraction and synthesisTwo review authors independently extracted data and assessed the quality of the included studies. Pooled HRs and 95% CIs were analysed using a random effects model. Heterogeneity was assessed using forest plots and I2 statistics.ResultsEight studies with 1121 patients with type 1 or type 2 diabetes were included in this meta-analysis, and the follow-up ranged from 17 to 70 months. The presence of myocardial fibrosis detected by LGE-MRI was associated with an increased risk for MACCEs (HR: 2.58; 95% CI 1.42 to 4.71; p=0.002) and MACEs (HR: 5.28; 95% CI 3.20 to 8.70; p<0.001) in patients with diabetes. Subgroup analysis revealed that ischaemic fibrosis detected by LGE was associated with MACCEs (HR 3.80, 95% CI 2.38 to 6.07; p<0.001) in patients with diabetes.ConclusionsThis study demonstrated that ischaemic myocardial fibrosis detected by LGE-MRI was associated with an increased risk of MACCEs/MACEs in patients with diabetes and may be an imaging biomarker for risk stratification. Whether LGE-MRI provides incremental prognostic information with respect to MACCEs/MACEs over risk stratification by conventional cardiovascular risk factors requires further study.

Abstract Background Prior studies demonstrated that myocardial fibrosis assessed by late gadolinium-enhanced (LGE) MRI is associated with an increased risk for major adverse cardiac and cerebrovascular events (MACCE) or major adverse cardiac events (MACE) in patients with diabetes. However, the results of these studies were controversial and limited. Therefore, we performed this meta-analysis assessing the associations of myocardial fibrosis detected by LGE with the risk of MACCE and MACE in patients with diabetes. Methods We selected studies using MEDLINE, EMBASE and Cochrane by Ovid on December 2019. Prospective and retrospective studies that assessed the associations of myocardial fibrosis detected by LGE with the risk of MACCE or MACE in patients with diabetes with a disease duration of at least 12 months. Two independent reviewers performed the data extraction using a standardized form. Pooled hazard ratios (HRs) and 95% confidence intervals (CIs) were evaluated by a random-effects model. Results Eight studies with 1121 patients were included in this meta-analysis, and follow-up of patients ranged from 17 to 70 months. The prevalence of LGE in the total sample was high, occurring in 38.09%. The annualized event rates (AERs) for MACCE was 11.94% in patients with diabetes and LGE. The presence of myocardial fibrosis detected by LGE was associated with an increased risk for MACCE (HR: 2.58; 95%CI 1.42-4.71; P=0.002) and MACE (HR: 5.28; 95%CI 3.20-8.70; P=0.000) in patients with diabetes. In a subgroup meta-analysis, ischemic fibrosis detected by LGE was associated with MACCE/MACE (HR 3.75, 95%CI 2.11-6.69; P=0.000) in patients with diabetes. In diabetic patients with preserved ejection fraction, the association between myocardial fibrosis detected by LGE and MACCE/MACE remained significant (HR: 4.02; 95%CI 2.22-7.25; P=0.000). All of the meta-analyses showed no significant heterogeneity from random effects. Conclusion This study demonstrated that myocardial fibrosis detected by LGE conferred an increase in the risk of MACCE/MACE in patients with diabetes and may be an imaging biomarker for risk stratification.

e16053 Background: Fluoropyrimidines such as 5-FU and capecitabine are known to be cardiotoxic drugs. TAS-102 (trifluridine-tipiracil) is a novel oral fluoropyrimidine that was recently FDA approved to treat gastric and colon cancer. However, the incidence of cardiac related events of TAS-102 is not fully ascertained. We performed a meta-analysis and systematic review to determine the incidence of cardiotoxic events associated with TAS-102. Methods: We performed a literature search through PubMed, Embase, and Web of Science to identify any publications in any language up to December 31st, 2019 where TAS-102 (and equivalent terms such as “trifluridine-tipiracil” and “Lonsurf”) was used. These were then manually reviewed to identify any publications reporting cardiac events. Randomized controlled trials (RCTs) were included for meta-analysis to determine the incidence of cardiotoxic events, which were summarized as pooled odds ratios (OR) when compared to placebo. Non-randomized, non-controlled clinical trials (phase I and phase II studies) were included in the systematic review but excluded from the pooled OR calculation. Results: 869 publications were identified in the initial literature search, of which 17 trials (3 Phase III studies, 6 Phase II studies, and 8 phase I studies) met inclusion criteria. A total of 1,877 patients among 4 RCTs were included in the meta-analysis. Compared with placebo, TAS-102 did not increase the risk of myocardial infarction (OR 1.97 95% CI [0.22-17.89]), hypertension (OR 0.73 95% CI [0.37, 1.44]), palpitations (OR 1.51 95% CI [0.30, 7.56]), cardio-pulmonary arrest (OR 0.83 95% CI [0.11-6.32]), or syncope (OR 1.50 95% CI [0.06-37.14]). Among the 1,252 patients receiving TAS-102, the overall incidence of cardiovascular events was low, with hypertension being the most common side effect (21 events), followed by palpitations (6 events), cardiopulmonary arrest (2 events), and myocardial infarction (3 events), though there was no statistically significant increased risk compared to placebo. No deaths were reported. Conclusions: Unlike other fluoropyrimidines, TAS-102 appears to be a cardiogentle drug, with no increased risk of cardiac events compared to placebo. Since fluoropyrimidines remain the backbone of treatment for gastrointestinal malignancies, TAS-102 can offer an alternative to patients who developed cardiotoxicities from other agents. Prospective studies with consideration of cardiac risk factors are required.

The intraperitoneal route of administration accounts for less than 1% of insulin treatment regimes in patients with diabetes mellitus type 1 (DM1). Despite being used for decades, a systematic review of various physiological effects of this route of insulin administration is lacking. Thus, the aim of this systematic review was to identify the physiological effects of continuous intraperitoneal insulin infusion (CIPII) compared to those of continuous subcutaneous insulin infusion (CSII) in patients with DM1. Four databases (EMBASE, PubMed, Scopus and CENTRAL) were searched beginning from the inception date of each database to 10th of July 2020, using search terms related to intraperitoneal and subcutaneous insulin administration. Only studies comparing CIPII treatment (≥ 1 month) with CSII treatment were included. Primary outcomes were long-term glycaemic control (after ≥ 3 months of CIPII inferred from glycated haemoglobin (HbA1c) levels) and short-term (≥ 1 day for each intervention) measurements of insulin dynamics in the systematic circulation. Secondary outcomes included all reported parameters other than the primary outcomes. The search identified a total of 2242 records; 39 reports from 32 studies met the eligibility criteria. This meta-analysis focused on the most relevant clinical end points; the mean difference (MD) in HbA1c levels during CIPII was significantly lower than during CSII (MD = -6.7 mmol/mol, [95% CI: -10.3 –-3.1]; in percentage: MD = -0.61%, [95% CI: -0.94 –- 0.28], p = 0.0002), whereas fasting blood glucose levels were similar (MD = 0.20 mmol/L, [95% CI: -0.34–0.74], p = 0.47; in mg/dL: MD = 3.6 mg/dL, [95% CI: -6.1–13.3], p = 0.47). The frequencies of severe hypo- and hyper-glycaemia were reduced. The fasting insulin levels were significantly lower during CIPII than during CSII (MD = 16.70 pmol/L, [95% CI: -23.62 –-9.77], p < 0.0001). Compared to CSII treatment, CIPII treatment improved overall glucose control and reduced fasting insulin levels in patients with DM1.

We performed a systematic review and meta-analysis to comprehensively determine the prevalence and the prognostic role of nonthyroidal illness syndrome (NTIS) in critically ill patients. We included studies that assessed thyroid function by measuring the serum thyroid hormone level and in-hospital mortality in adult septic patients. Reviews, case reports, editorials, letters, animal studies, duplicate studies, and studies with irrelevant populations and inappropriate controls were excluded. A total of 6869 patients in 25 studies were included. The median prevalence rate of NTIS was 58% (IQR 33.2-63.7). In univariate analysis, triiodothyronine (T3) and free T3 (FT3) levels in non-survivors were relatively lower than that of survivors (8 studies for T3; standardized mean difference (SMD) 1.16; 95% confidence interval (CI), 0.41–1.92; I2 = 97%; P < 0.01). Free thyroxine (FT4) levels in non-survivors were also lower than that of survivors (12 studies; SMD 0.54; 95% CI, 0.31–0.78; I2 = 83%; P < 0.01). There were no statistically significant differences in TSH levels between non-survivors and survivors. NTIS was independently associated with increased risk of mortality in critically ill patients (OR = 2.21, 95% CI 1.64.- 2.97, I2 = 65% p < 0.01) The results favor the concept that decreased thyroid function might be associated with a worse outcome in critically ill patients. Hence, the measurement of TH could provide prognostic information on mortality in adult patients admitted to ICU.

Background: Patients with diabetes mellitus (DM) are known to have reduced life expectancy and be at increased risk for multiple morbidities including serious infection. However, published data on DM outcomes after left ventricular assist device (LVAD) implantation are sparse, inconsistent and individual studies are small with limited power. We conducted a systematic review and meta-analysis to compare survival and adverse events post-LVAD in DM versus non-DM (NDM) patients. Methods: Medline, Scopus and Cochrane Central databases were searched for studies comparing outcomes in DM and NDM patients undergoing LVAD implantation for advanced heart failure (HF) from inception-February 2018. Outcomes included all-cause mortality (30-day and one-year), device-related infection, ischemic stroke, hemorrhagic stroke and major bleeding. Results were reported as random effect risk ratios (RR) with 95 % confidence intervals. Results: We identified 5 retrospective cohort studies, at low risk of bias, reporting on 1,351 patients (n=488 DM). There was a borderline significant, increased 30-day mortality (RR: 1.57 [1.00, 2.47]; p=0.05; I 2 =0%) among DM vs. NDM. The DM and NDM groups did not differ significantly in terms of 1-year mortality (RR: 1.15 [0.98, 1.35]; p=0.08; I 2 =39%), device-related infection (RR: 1.05 [0.92, 1.19]; p=0.88; I 2 =0%), ischemic stroke (RR: 1.29 [0.91, 1.83]; p=0.69; I 2 =0%), hemorrhagic stroke (RR: 1.10 [0.42, 2.83]; p=0.85; I 2 =69%), and bleeding (RR: 1.06 [0.80, 1.40]; p=0.70; I 2 =27%). Conclusion: Following LVAD implantation, patients with DM, versus patients without, have a modestly elevated 30-day mortality rate. However, 1-year mortality rates, device related infection, and bleeding rates were not different.

ObjectiveStroke is a major cause of disability and death worldwide. People with diabetes are at a twofold to fivefold increased risk for stroke compared with people without diabetes. This study systematically reviews the literature on available stroke prediction models specifically developed or validated in patients with diabetes and assesses their predictive performance through meta-analysis.DesignSystematic review and meta-analysis.Data sourcesA detailed search was performed in MEDLINE, PubMed and EMBASE (from inception to 22 April 2019) to identify studies describing stroke prediction models.Eligibility criteriaAll studies that developed stroke prediction models in populations with diabetes were included.Data extraction and synthesisTwo reviewers independently identified eligible articles and extracted data. Random effects meta-analysis was used to obtain a pooled C-statistic.ResultsOur search retrieved 26 202 relevant papers and finally yielded 38 stroke prediction models, of which 34 were specifically developed for patients with diabetes and 4 were developed in general populations but validated in patients with diabetes. Among the models developed in those with diabetes, 9 reported their outcome as stroke, 23 reported their outcome as composite cardiovascular disease (CVD) where stroke was a component of the outcome and 2 did not report stroke initially as their outcome but later were validated for stroke as the outcome in other studies. C-statistics varied from 0.60 to 0.92 with a median C-statistic of 0.71 (for stroke as the outcome) and 0.70 (for stroke as part of a composite CVD outcome). Seventeen models were externally validated in diabetes populations with a pooled C-statistic of 0.68.ConclusionsOverall, the performance of these diabetes-specific stroke prediction models was not satisfactory. Research is needed to identify and incorporate new risk factors into the model to improve models’ predictive ability and further external validation of the existing models in diverse population to improve generalisability.

Abstract Background Atrial fibrillation (AF) is a common arrhythmia classified as paroxysmal and non-paroxysmal. Non-paroxysmal AF is associated with an increased risk of complications. Diabetes contributes to AF initiation, yet its role in AF maintenance is unclear. We conducted a systematic review and meta-analysis to summarize the evidence regarding the association of diabetes with AF types. Methods We searched 5 databases for observational studies investigating the association of diabetes with the likelihood of an AF type (vs another type) in humans. Study quality was evaluated using the Newcastle–Ottawa Scale. Studies classifying AF types as paroxysmal (reference) and non-paroxysmal were pooled in a meta-analysis using random effects models. Results Of 1997 articles we identified, 20 were included in our systematic review. The population sample size ranged from 64 to 9816 participants with mean age ranging from 40 to 75 years and percentage of women from 24.8 to 100%. The quality of studies varied from poor (60%) to fair (5%) to good (35%). In the systematic review, 8 studies among patients with AF investigated the cross-sectional association of diabetes with non-paroxysmal AF (vs paroxysmal) of which 6 showed a positive association and 2 showed no association. Fourteen studies investigated the longitudinal association of diabetes with “more sustained” AF types (vs “less sustained”) of which 2 showed a positive association and 12 showed no association. In the meta-analysis of cross-sectional studies, patients with AF and diabetes were 1.31-times more likely to have non-paroxysmal AF than those without diabetes [8 studies; pooled OR (95% CI), 1.31 (1.13–1.51), I2 = 82.6%]. The meta-analysis of longitudinal studies showed that for patients with paroxysmal AF, diabetes is associated with 1.32-times increased likelihood of progression to non-paroxysmal AF [five studies; pooled OR (95% CI), 1.32 (1.07–1.62); I2 = 0%]. Conclusions Our findings suggest that diabetes is associated with an increased likelihood of non-paroxysmal AF rather than paroxysmal AF. However, further high quality studies are needed to replicate these findings, adjust for potential confounders, elucidate mechanisms linking diabetes to non-paroxysmal AF, and assess the impact of antidiabetic medications on AF types. These strategies could eventually help decrease the risk of non-paroxysmal AF among patients with diabetes.

Abstract Background: Diabetes mellitus (DM) could be classified as type 1 diabetes mellitus (T1DM), type 2 diabetes mellitus (T2DM), gestational diabetes mellitus (GDM) and others according to etiology and pathology. Diabetic nephropathy (DN) is one of the most serious complications of DM. YKL-40 is a marker of inflammation and some studies have indicated that DM was related with inflammation. The objective of our study is to perform a systematic review and meta-analysis to confirm the relationship between YKL-40 and DM as well as DN.Methods: Pubmed, Embase, CNKI and Chinese wanfang databases were searched for eligible studies by two independent authors. Studies were included in this meta-analysis if they fulfilled the following inclusion criteria: (1) a study involving the role of YKL-40 in DM (or DN) designed as a case-control study or cohort study; (2) the data of serum YKL-40 levels were available; (3) studies were published in English or Chinese.Results: Twenty-five studies involving 2498 DM patients and 1424 healthy controls were included. Compared with healthy controls, DM patients had significantly higher levels of YKL-40 (DM: SMD=1.62, 95%CI, 1.08 to 2.25, P=0.000; GDM: SMD=2.85, 95%CI, 1.01 to 4.70, P=0.002). Additionally, DM patients with different degree of albuminuria had significantly higher levels of YKL-40 compared with healthy controls (normoalbuminuria: SMD=1.58, 95%CI, 0.59 to 2.56, P=0.002; microalbuminuria: SMD=2.57, 95%CI, 0.92 to 4.22, P=0.002; macroalbuminuria: SMD=2.69, 95%CI, 1.40 to 3.98, P=0.000) and serum YKL-40 levels increased with increasing severity of albuminuria among DM patients (microalbuminuria vs normoalbuminuria: SMD=1.49, 95%CI, 0.28 to 2.71, P=0.016; macroalbuminuria vs microalbuminuria: SMD=0.93, 95%CI, 0.34 to 1.52, P=0.002).Conclusions: DM patients have higher levels of YKL-40 compared with healthy controls. Additionally, levels of YKL-40 are significantly higher in DM patients with different degree of albuminuria than in the healthy controls and the levels of YKL-40 are positively related with the severe degree of albuminuria. Therefore, our current meta-analysis suggests that their sera should be detected for YKL-40, if DM, especially DN, is suspected in patients.
