Abstract
Dipeptidyl peptidase-4 inhibitors (DPP4is) and sodium glucose cotransporter-2 inhibitors (SGLT2is) have been speculated to have a potential to increase infection risks in type 2 diabetes mellitus (T2DM) patients. We performed a cohort study using the Korean health insurance data to investigate infection risks with each drug class relative to metformin in insulin-treated T2DM patients. After propensity score matching, we included 1,498 and 749 patients in DPP4i + insulin vs metformin + insulin and 300 and 549 patients in SGLT2i + insulin vs metformin + insulin, respectively. In stratified analyses per patient factor, none of the odds ratios (ORs) were associated with a statistical significance across respiratory, genital, and urinary tract infections (UTIs), except that of the male stratum for respiratory infections (OR 0.77, p = 0.04). With regard to SGLT2is, a higher risk of genital infections was analyzed with their use than with metformin therapy (OR 1.76, p = 0.03). In stratified analyses, the OR for genital infections remained significant in the baseline cardiovascular disease stratum (OR 2.29, p = 0.01). No increased UTI risk was detected with SGLT2is compared against metformin. In this study on insulin-receiving T2DM patients, DPP4is were not associated with increased infection risks, whereas SGLT2is led to a higher risk for genital infections, but not for UTIs, relative to metformin.

Abstract
Sodium‐glucose cotransporter‐2 (SGLT‐2) inhibitors are antidiabetic drugs with associated safety concerns regarding the risk of genital and urinary tract infections. This study assessed the risk of genital and urinary tract infections associated with prescription of SGLT‐2 inhibitors as an add‐on therapy to metformin in patients with type 2 diabetes mellitus (T2DM) compared to dipeptidyl peptidase‐4 (DPP‐4) inhibitors, sulfonylurea (SU), and thiazolidinedione (TZD). We conducted a retrospective cohort study using the NHIS—National Health Insurance—Database in Korea from 2014 to 2017. Patients aged ≥19 years and those diagnosed with T2DM prior to drug prescription were enrolled. The outcomes were genital and urinary tract infections. Analysis was performed using Cox's proportional hazard model following 1:1 propensity score matching to calculate the hazard ratio (HR) with a 95% confidence interval (CI). Among the 107 131 patients included in the study, a total of 7738, 7145, and 2175 patients were assigned to the DPP‐4 inhibitors, SU, and TZD comparator groups, using the propensity score (PS) of each comparator based on 7741 people in the assessed drug SGLT‐2 inhibitor group. SGLT‐2 inhibitors were associated with a higher risk of genital infections than DPP‐4 inhibitors (HR: 2.39, 95% CI: 2.07–2.76), SU (HR: 3.23, 95% CI: 2.73–3.81), and TZD (HR: 3.23, 95% CI: 2.35–4.44), as an add‐on therapy to metformin. Similar results were observed for the risk of urinary tract infections. In conclusion, SGLT‐2 inhibitors are significantly associated with a higher risk of genital and urinary tract infections compared to DPP‐4 inhibitors, SU, and TZD.

Abstract
PURPOSE Current guidelines recommend withholding sodium-glucose cotransporter 2 inhibitors perioperatively due to concerns of euglycaemic diabetic ketoacidosis. However, such guidelines are largely based on case reports and small case series, many extrapolated from non-surgical patients. The aim was to investigate whether withholding sodium-glucose cotransporter 2 inhibitors as per current perioperative guidelines was associated with a reduction in serious adverse events, including euglycaemic diabetic ketoacidosis. METHODS Instances of perioperative management of sodium-glucose cotransporter 2 inhibitors, over a four-year period were classified into two categories: those where sodium-glucose cotransporter 2 inhibitors were withheld as per guidelines and those where sodium-glucose cotransporter 2 inhibitors were administered in the perioperative period. The primary outcome was 'total major perioperative complications': a composite of serious adverse events including euglycaemic diabetic ketoacidosis, diabetic ketoacidosis, acute kidney injury, urosepsis and death. RESULTS Eighty-two instances in 64 patients were included. Withholding sodium-glucose cotransporter 2 inhibitors was associated with an increased incidence of total major perioperative complications and poorer glycaemic control postoperatively. Multivariable logistic regression analysis revealed that withholding sodium-glucose cotransporter 2 inhibitors perioperatively (OR = 13.15; 95% CI = 1.8-138.9) and preoperative urea (OR 1.85 (95% CI = 1.17-3.43) were independently associated with an increase in total major postoperative complications. CONCLUSION Withholding sodium-glucose cotransporter 2 inhibitors as per current guidelines was associated with an increase in postoperative complications and reduced glycaemic control.

Abstract
AIM We examined eligibility and preventable cardiovascular disease events in US adults with diabetes mellitus from the Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients (EMPA-REG OUTCOME). METHODS We identified adults with diabetes mellitus eligible for EMPA-REG OUTCOME based on trial eligibility criteria available from the National Health and Nutrition Examination Surveys, 2007-2016. We estimated composite cardiovascular disease endpoints, as well as all-cause deaths, death from cardiovascular disease and hospitalizations for heart failure from trial treatment and placebo event rates, the difference indicating the preventable events. RESULTS Among 29,629 US adults aged ⩾18 years (representing 231.9 million), 4672 (27.3 million) had diabetes mellitus, with 342 (1.86 million) meeting eligibility criteria of EMPA-REG OUTCOME. We estimated from trial primary endpoint event rates of 10.5% and 12.1% in the empagliflozin and placebo groups, respectively, that based on the 'treatment' of our 1.86 million estimated EMPA-REG OUTCOME eligible subjects, 12,066 (95% confidence interval: 10,352-13,780) cardiovascular disease events could be prevented annually. Estimated annual preventable deaths from any cause, cardiovascular causes and hospitalizations from heart failure were 17,078 (95% confidence interval: 14,652-19,504), 14,479 (95% confidence interval: 12,422-16,536) and 9467 (95% confidence interval: 8122-10,812), respectively. CONCLUSION Empagliflozin, if provided to EMPA-REG OUTCOME eligible US adults, may prevent many cardiovascular disease events, cardiovascular and total deaths, as well as heart failure hospitalizations.

Abstract
BACKGROUND Controversies exist regarding the optimal blood pressure (BP) level that is safe and provides cardiovascular protection in patients with type 2 diabetes mellitus (T2DM) and coexistent coronary artery disease. Several new glucose-lowering agents have been found to lower BP as well, making the interaction between BP and T2DM even more complex. METHODS With the reference to recent literature, this review article describes the potential mechanisms of increased risk of hypertension in T2DM and outlines the possible optimal BP levels based upon recommendations on the management of hypertension by the current guidelines, in combination with our research findings, for type 2 diabetic patients with coronary artery disease. RESULTS The development of hypertension in T2DM involves multiple processes, including enhanced sympathetic output, inappropriate activation of renin-angiotensin- aldosterone system, endothelial dysfunction induced through insulin resistance, and abnormal sodium handling by the kidney. Both AGE-RAGE axis and adipokine dysregulation activate intracellular signaling pathways, increase oxidative stress, and aggravate vascular inflammation. Pancreatic β-cell specific microRNAs are implicated in gene expression and diabetic complications. Non-pharmacological intervention with lifestyle changes improves BP control, and anti-hypertensive medications with ACEI/ARB, calcium antagonists, β-blockers, diuretics and new hypoglycemic agent SGLT2 inhibitors are effective to decrease mortality and prevent major adverse cardiovascular events. For hypertensive patients with T2DM and stable coronary artery disease, control of BP < 130/80 mmHg but not < 120/70 mmHg is reasonable, whereas for those with chronic total occlusion or acute coronary syndromes, an ideal BP target may be somewhat higher (< 140/90 mmHg). Caution is advised with aggressive lowering of diastolic BP to a critical threshold (< 60 mmHg). CONCLUSIONS Hypertension and T2DM share certain similar aspects of pathophysiology, and BP control should be individualized to minimize adverse events and maximize benefits especially for patients with T2DM and coronary artery disease.

Abstract
Sodium-glucose cotransporter 2 inhibitors (SGLT2Is) can be associated with euglycemic diabetic ketoacidosis (eDKA). Severe metabolic acidosis with extreme electrolyte abnormalities can occur with nonsignificant blood glucose elevations in SGLT2I-treated patients. Additional risk factors for eDKA include prolonged fasting, major illness, large weight loss, and reductions in insulin doses.

Abstract
BACKGROUND AND OBJECTIVE Empagliflozin and canagliflozin decreased the risk of major adverse cardiovascular events (MACE) compared with placebo in randomized clinical trials which were conducted to evaluate their cardiovascular risks. However, canagliflozin increased the risks of amputation and bone fracture, and the reasons for these observed differences remain unclear. The objective of this study was to evaluate the safety risks, specifically the risks of amputation and bone fracture, associated with sodium-glucose cotransporter 2 (SGLT2) inhibitors by using the difference in restricted mean survival time (RMST), an alternative measure to the hazard ratio. METHODS This study included all the randomized clinical trials with cardiovascular events as a primary endpoint, comparing SGLT2 inhibitors with placebo in patients with type 2 diabetes mellitus, the results of which have been published as of 11 September 2018: EMPA-REG OUTCOME (empagliflozin) and CANVAS Program (canagliflozin). We reevaluated these trials by estimating RMSTs based on the reconstructed individual patient data for each time-to-event outcome from publicly available information. RESULTS The differences of RMSTs (SGLT2 inhibitors minus placebo: point estimate and 95% confidence interval) for lower-extremity amputations and low-trauma fracture were - 20 days (- 30, - 10) and - 15 days (- 30, 0), respectively, in CANVAS Program (2190 days follow-up). That for lower-limb amputation was 1 day (- 6, 8) in EMPA-REG OUTCOME (1440 days follow-up). Regarding the MACE, both empagliflozin and canagliflozin statistically significantly decreased the risk compared with placebo. CONCLUSIONS Canagliflozin was shown to increase the risks of amputation and bone fracture compared with placebo when using the difference in RMST.

Abstract
PURPOSE OF REVIEW Moderate hypertriglyceridemia is exceedingly common in diabetes, and there is growing evidence that it contributes to residual cardiovascular risk in statin-optimized patients. Major fibrate trials yielded inconclusive results regarding the cardiovascular benefit of lowering triglycerides, although there was a signal for improvement among patients with high triglycerides and low high-density lipoprotein (HDL)-the "diabetic dyslipidemia" phenotype. Until recently, no trials have examined a priori the impact of triglyceride lowering in patients with diabetic dyslipidemia, who are likely among the highest cardiovascular-risk patients. RECENT FINDINGS In the recent REDUCE IT trial, omega-3 fatty acid icosapent ethyl demonstrated efficacy in lowering cardiovascular events in patients with high triglycerides, low HDL, and statin-optimized low-density lipoprotein (LDL). The ongoing PROMINENT trial is examining the impact of pemafibrate in a similar patient population. Emerging evidence suggests that lowering triglycerides may reduce residual cardiovascular risk, especially in high-risk patients with diabetic dyslipidemia.

Abstract
In the last years, due to new regulatory guidelines requiring a stringent documentation of cardiovascular (CV) safety of novel drugs for type 2 diabetes, cardiovascular outcomes safety trials (CVOTs) are requested. CVOTs increase the knowledge about the safety profile of the new drugs, but they have intrinsic limits that make difficult their transferability to clinical practice. For this reason, real world evidence is considered an important complement to experimental data. Among the glucagon-like peptide-1 receptor agonists, liraglutide in the LEADER CVOT demonstrated superiority in reducing the risk of major CV events (MACEs) vs. placebo. We conducted an observational, retrospective, longitudinal study based on 307 patients with T2DM treated with liraglutide under routine clinical practice conditions. Real world impact of liraglutide on metabolic control, CV risk factors, hypoglycemia and CV events was assessed. Improvements during 36 months were found in HbA1c (-1.0%; p < 0.0001), fasting blood glucose (-17.6 mg/dL; p < 0.0001), body weight (-3.2 kg; p < 0.0001), waist circumference (-1.45 cm; p = 0.004), systolic blood pressure (-10.41 mmHg; p < 0.0001), diastolic blood pressure (-3.69 mmHg; p < 0.0001), total cholesterol (-7.96 mg/dL; p =0.008) and triglycerides (-20.60 mg/dl; p = 0.01). No severe hypoglycemia occurred. Incidence of MACEs in this cohort was lower than in the LEADER study (2.59 vs. 3.4 events per 100 person-years), confirming CV safety of liraglutide even in the real world. On the other hand, a higher incidence of CV event in patients with established CV disease was documented (8.1 events per 100 person-years), in spite of the use of liraglutide. In conclusion, 36-month durability and CV safety of liraglutide were documented in a real world cohort of T2DM patients, with sustained benefits on a large array of CV risk factors.

Abstract
Sodium-glucose cotransporter type 2 inhibitors (SGLT2is) and glucagon-like peptide-1 receptor agonists (GLP-1RAs) are two pharmacological classes that have proven their efficacy to reduce major cardiovascular events (MACEs) in patients with type 2 diabetes mellitus (T2DM) and established cardiovascular disease in large prospective cardiovascular outcome trials (CVOTs): EMPA-REG OUTCOME (empagliflozin), CANVAS (canagliflozin), LEADER (liraglutide) and SUSTAIN 6 (semaglutide). Some heterogeneity appears to exist between the various agents within the two pharmacological classes. Whether these positive results could be extrapolated to patients without cardiovascular disease is still unknown. The underlying mechanisms remain a matter of debate but appear to differ between SGLT2is and GLP-1RAs. One crucial question is which patient's characteristics should be taken into account to guide the choice between a SGLT2i or a GLP-1RA according to a personalized approach. Heart failure should encourage the use of a SGLT2i whereas moderate to severe chronic kidney disease should favour the prescription of a GLP-1RA. Despite the results of recent CVOTs, numerous patients who are good candidates for benefiting of these agents do not receive them in clinical practice. Currently, there is a paradigm shift in T2DM management, moving from a primary objective of glucose control to a cardiovascular and renal protection.

Abstract
Mitochondrial dysfunction has been implicated in the development of heart failure. Oxidative metabolism in mitochondria is the main energy source of the heart, and the inability to generate and transfer energy has long been considered the primary mechanism linking mitochondrial dysfunction and contractile failure. However, the role of mitochondria in heart failure is now increasingly recognized to be beyond that of a failed power plant. In this Review, we summarize recent evidence demonstrating vicious cycles of pathophysiological mechanisms during the pathological remodeling of the heart that drive mitochondrial contributions from being compensatory to being a suicide mission. These mechanisms include bottlenecks of metabolic flux, redox imbalance, protein modification, ROS-induced ROS generation, impaired mitochondrial Ca2+ homeostasis, and inflammation. The interpretation of these findings will lead us to novel avenues for disease mechanisms and therapy.
