ABSTRACTImportanceSARS-CoV-2 is associated with multiple direct and indirect effects to the heart. It is not yet well defined whether patient groups at increased risk of severe respiratory disease due to SARS-CoV-2 infection also experience a heightened incidence of cardiac complications.ObjectiveWe sought to analyse the role of pre-existing chronic disease (chronic respiratory illness, cardiovascular disease (CVD), hypertension and diabetes mellitus) in the development of cardiac complications from SARS-CoV-2.Data SourcesWe retrospectively investigated published (including pre-prints), publicly released, de-identified, data made available between Dec 1, 2019, and May 11, 2020. Information was accessed from PubMed, Embase, medRxiv and SSRN.Study Selection379 full-text articles were reviewed and 321 excluded for lack of original research, irrelevance to outcome, inappropriate cohort, or small patient numbers (case reports of <10 patients). Data were extracted from two studies and the remaining 56 contacted to request appropriate data, to which three responded with data contributions. A final of five studies were included.Data Extraction and SynthesisThis systematic review was conducted based on PRISMA and MOOSE statements. Included studies were critically appraised using Newcastle Ottawa Quality Assessment Scale (NOS). Data were extracted independently by multiple observers. A fixed-effects model was selected for the meta-analysis based on relatively low heterogeneity between the studies (I2<50%).Main Outcome and MeasuresCardiac complications were determined via blood levels of cardiac biomarkers above the 99th percentile of the upper reference limit, abnormalities in electrocardiography, and/or abnormalities in echocardiography.ResultsSARS-CoV-2-infected patients who developed cardiac complications were, on average, 10 years older than those that did not. Pooled analyses showed the development of cardiac complications from SARS-CoV-2 was significantly increased in patients with underlying chronic respiratory illness (OR 2.88[1.45,5.71]), CVD (OR 5.12[3.09,8.48]), hypertension (OR 4.37[2.99,6.39]) and diabetes mellitus (OR 2.61[1.67,4.09]).Conclusions and RelevanceOlder age and pre-existing chronic respiratory illness, CVD, hypertension, and diabetes mellitus may represent prognostic factors for the development of additional cardiac complications in COVID-19, highlighting the need for a multidisciplinary approach to chronic disease patient management and providing justification for a larger scale observational study.

Background:Post-operative cognitive dysfunction (POCD) occurs frequently after major surgery. Hypertension is well-established as a risk factor for age-related cognitive impairment, but it is unclear whether or not it also increases the risk of POCD.Objective:To evaluate the role of hypertension in POCD risk in a systematic review and meta-analysis.Method:PubMed, Ovid SP and the Cochrane Database of Systematic Reviews were searched for longitudinal studies of adults undergoing surgery with reporting of hypertension, blood pressure and/or anti-hypertensive treatment associations with POCD as relative risks or odds ratios. Fixed-effects meta-analyses were performed using Review Manager (version 5.3).Results:Twenty-four studies on 4317 patients (mean age 63 years) were included. None of the studies had set out to assess hypertension as a risk factor for POCD. Hypertension was used as a categorical predictor throughout and only 2 studies adjusted for potential confounders. Across all 24 studies, hypertension was not significantly associated with POCD risk (RR 1.01; 95% CI 0.93, 1.09;p=0.82), though among 8 studies with >75% males, we found hypertension associations with a 27% increased risk of POCD (RR 1.27, 95% CI 1.07, 1.49;p=0.005).Conclusion:Our findings do not support the hypothesis that hypertension is a risk factor for POCD. However, since none of the studies included in our analysis were hypothesis-driven and most did not adjust for potential confounders, further systematic investigations are needed to evaluate the role of hypertension in the epidemiology of POCD.

Background:Studies pertaining to association of GSTM1 and GSTT1 null genotypes with risk of T2DM and its complications were often inconclusive, thus spurring the present study.Methods:Meta-analysis of 25 studies for evaluating the role of GSTM1/GSTT1 null polymorphisms in determining the risk for T2DM and 17 studies for evaluating the role of GSTM1/GSTT1 null polymorphisms in development of T2DM related complications were conducted.Results:Our study revealed an association between GSTM1 and GSTT1 null polymorphism with T2DM (GSTM1; OR=1.37;95% CI =1.10-1.70 and GSTT1; OR=1.29;95% CI =1.04-1.61) with an amplified risk of 2.02 fold for combined GSTM1-GSTT1 null genotypes. Furthermore, the GSTT1 null (OR=1.56;95%CI=1.38-1.77) and combined GSTM1-GSTT1 null genotypes (OR=1.91;95%CI=1.25- 2.94) increased the risk for development of T2DM related complications, but not the GSTM1 null genotype. Stratified analyses based on ethnicity revealed GSTM1 and GSTT1 null genotypes increase the risk for T2DM in both Caucasians and Asians, with Asians showing much higher risk of T2DM complications than Caucasians for the same. </P><P> Discussion: GSTM1, GSTT1 and combined GSTM1-GSTT1 null polymorphism may be associated with increased risk for T2DM; while GSTT1 and combined GSTM1-GSTT1 null polymorphism may increase the risk of subsequent development of T2DM complications with Asian population carrying an amplified risk for the polymorphism.Conclusion:Thus GSTM1 and GSTT1 null genotypes increases the risk for Type 2 diabetes mellitus alone, in combination or with regards to ethnicity.

Objective. Type 2 deiodinase (Dio2) is an enzyme responsible for the conversion of T4 to T3. The Thr92Ala polymorphism has been shown related to an increased risk for developing type 2 diabetes mellitus (T2DM). The aim of this study is to assess the association between this polymorphism and glycemic control in T2DM patients as marked by the HbA1C levels.Design and Methods.The terms “rs225014,” “thr92ala,” “T92A,” or “dio2 a/g” were used to search for eligible studies in the PubMed, Embase, and Cochrane databases and Google Scholar. A systematic review and meta-analysis of studies including both polymorphism testing and glycated hemoglobin (HbA1C) assays were performed.Results. Four studies were selected, totaling 2190 subjects. The pooled mean difference of the studies was 0.48% (95% CI, 0.18–0.77%), indicating that type 2 diabetics homozygous for the Dio2 Thr92Ala polymorphism had higher HbA1C levels.Conclusions. Homozygosity for the Dio2 Thr92Ala polymorphism is associated with higher HbA1C levels in T2DM patients. To confirm this conclusion, more studies of larger populations are needed.

Procedural Complications

Introduction: Women undergoing atrial fibrillation catheter ablation (AFCA) have higher rates of vascular complications and major bleeding. However, studies have been underpowered to detect differences in rare complications such as stroke/transient ischemic attack (TIA) and procedural mortality. Methods: We performed a systematic review of databases (PubMed, World of Science, Embase) to identify studies published since 2010 reporting AFCA complications by gender. Six complications of interest were: 1) vascular/groin complications; 2) pericardial effusion/tamponade; 3) stroke/TIA; 4) permanent phrenic nerve injury; 5) major bleeding & 6) procedural mortality. For meta-analysis, random effects models were used when heterogeneity between studies was ≥ 50% (vascular complications, major bleeding) and fixed effects models for other endpoints. Results: Of 5716 citations, 19 studies met inclusion criteria, comprising 244,353 patients undergoing AFCA, of whom 33% were women. Women were older (65.3 ± 11.2 vs. 60.4 ± 13.2 years), more likely hypertensive (60.6 vs. 55.5%) and diabetic (18.3 vs. 16.5%) and had higher CHA 2 DS 2 -VASc scores (3.0 ± 1.8 vs. 1.4 ± 1.4) (p<0.0001 for all comparisons). The rates of all 6 complications were significantly higher in women (Table). However, despite statistically significant differences, the overall incidences of major complications were very low in both genders: stroke/TIA (women 0.51 vs. men 0.39%) and procedural mortality (women 0.25 vs. men 0.18%). Conclusion: Women experience significantly higher rates of AFCA complications. However, the incidence of major procedural complications is very low in both genders. The higher rate of complications in women may be partially attributable to older age and a higher prevalence of comorbidities at the time of ablation. More detailed studies are needed to better define the mechanisms of increased risk in women and to identify strategies for closing the gender gap.

71 Background: Patients treated with androgen receptor inhibitors (ARIs) report a higher incidence of falls; although a potential mechanism of action is unknown. This systematic review evaluates the relative risk (RR) of fall and fracture in prostate cancer (PCa) patients that receive ARIs. Methods: We conducted a comprehensive literature search using Cochrane, Scopus and MedlinePlus databases from inception through August 2019, and evaluated all published prospective phase II, III and IV randomized controlled trials that treated PCa patients with ARIs. Reported fall and fractures as adverse events (AEs) were extracted for analysis. Retrospective, phase I, non-randomized phase II, and studies with control arms that used one of the ARIs were excluded. A mixed effects model was used to estimate effects of ARI on the RR, with the included studies treated as random effects and study arms treated as fixed effects in the pooled analysis. Sample size for each study was used to weight the mixed model. Results: Eleven studies met our inclusion criteria. The total population was 11,382; 6536 were in the ARI arm and 4846 in the control (CTL) arm. Study types were: 8 phase III; 2 phase II; 1 phase IV. Subjects in the ARI arm received enzalutamide, apalutamide or darolutamide in combination with androgen deprivation therapy or other enzalutamide combinations while in the CTL arm received placebo, bicalutamide or abiraterone. Treatment duration ranged from 5.4 to 20.5 mo for ARI vs. 5.4 to 18.3 mo for CTL. The reported incidence of fall was 481 (7.4%) in ARI and 201 (4.1%) for CTL. The incidence of fracture was 204 (3.1%) in ARI and 93 (1.9%) in control. The use of ARI was associated with an increased risk: all fall grades (RR 1.83; 95% CI 1.56-2.15; p <0.01); high grade fall (RR 1.69; 95% CI 1.09 – 2.62; p=0.019); all grade fracture (RR 1.56; 95% CI 1.23-1.97; p <0.01) and likely high grade fracture (RR 1.62; 95% CI 0.97 – 2.69; p=0.063). Conclusions: The use of ARI significantly increases falls and fractures in PCa patients as assessed by this meta-analysis study. Further studies would be warranted to identify and understand potential mechanisms and develop strategies to decrease falls and fractures associated with ARI use.

Background. Environmental factors and genetic mutations have been increasingly recognized as risk factors for chronic pancreatitis (CP). ThePRSS1p.R122H mutation was the first discovered to affect hereditary CP, with 80% penetrance. We performed here a systematic review and meta-analysis to evaluate the associations ofPRSS1p.R122H mutation with CP of diverse etiology.Methods. The PubMed, EMBASE, and MEDLINE database were reviewed. The pooled odds ratio (OR) with 95% confidence intervals was used to evaluate the association of p.R122H mutation with CP. Initial analysis was conducted with all etiologies of CP, followed by a subgroup analysis for hereditary and nonhereditary CP, including alcoholic or idiopathic CP.Results. A total of eight case-control studies (1733 cases and 2415 controls) were identified and included. Overall,PRSS1p.R122H mutation was significantly associated with an increased risk of CP (OR = 4.78[1.13–20.20]). Further analysis showed p.R122H mutation strongly associated with the increased risk of hereditary CP (OR = 65.52[9.09–472.48]) but not with nonhereditary CP, both alcoholic and idiopathic CP.Conclusions. Our study showing the differential role of p.R122H mutation in various etiologies of CP indicates that this complex disorder is likely influenced by multiple genetic factors as well as environmental factors.

BackgroundThe ATP-binding cassette transporter A1 (ABCA1) is likely associated with the risk of type 2 diabetes mellitus (T2DM) via β cell function modification, but the evidence on the association remains unclear. This study aimed to investigate the relationship between the ABCA1 69C&gt;T polymorphism and the risk of T2DM through a systematic review and meta-analysis.Materials and MethodsThe PubMed, Web of Science, and Embase databases were searched for qualified studies published until August 2020. Studies that included the association between the ABCA1 69C&gt;T polymorphism and the risk of T2DM were reviewed. The odds ratios (ORs) and 95% confidence intervals (CIs) were evaluated.ResultsWe analyzed data from a total of 10 studies involving 17,742 patients. We found that the CC or CT genotype was associated with increased risk of T2DM than the TT genotype (OR, 1.41; 95% CI, 1.02-1.93). In the Asian population, the C allele carriers had a higher risk of T2DM than those with the TT genotype; the ORs of the CC and CT genotypes were 1.80 (95% CI, 1.21-2.68) and 1.61 (95% CI, and 1.29-2.01), respectively.ConclusionsThis meta-analysis confirmed that the ABCA1 69C&gt;T genotype showed a decrease risk of T2DM compared to the CC or CT genotypes.
