Abstract
BACKGROUND Preventing postoperative recurrence (POR) is a major concern in Crohn's disease (CD). While azathioprine is an option, no data is available on ustekinumab efficacy in this situation. AIMS We compared the effectiveness of ustekinumab versus azathioprine in preventing endoscopic POR in CD. METHODS We retrospectively collected data from all consecutive CD patients treated with ustekinumab after intestinal resection in 9 centers. The control group (azathioprine alone) was composed of patients who participated in a randomized controlled trial conducted in the same centers comparing azathioprine alone or in combination with curcumin. Propensity score analyses (inversed probability of treatment weighting = IPTW) were applied to compare the two groups. The primary endpoint was endoscopic POR (Rutgeerts' index ≥ i2) at 6 months. RESULTS Overall, 32 patients were included in the ustekinumab group and 31 in the azathioprine group. The propensity score analysis was adjusted on the main risk factors (smoking, fistulizing phenotype, prior bowel resection, resection length >30 cm and ≥2 biologics before surgery) and thiopurines or ustekinumab exposure prior to surgery making the two arms comparable (∣d∣ < 0.2). After IPTW, the rate of endoscopic POR at 6 months was lower in patients treated with ustekinumab compared to azathioprine (28.0% vs. 54.5%, p = 0.029). After IPTW, the rates of i2b-endoscopic POR (Rutgeerts' index ≥ i2b) and severe endoscopic POR (Rutgeerts' index ≥ i3) were 20.8% versus 42.5% (p = 0.066) and 16.9% versus 27.9% (p = 0.24), in the ustekinumab and azathioprine groups, respectively. CONCLUSION Ustekinumab seemed to be more effective than azathioprine in preventing POR in this cohort of CD patients.

Abstract
BACKGROUND Atrial fibrillation (AF) is the most common cardiac arrhythmia. Catheter ablation aims to restore sinus rhythm. However, relapses occur in up to 30% of patients. A Mediterranean diet (MedDiet) enriched with extra-virgin olive oil (EVOO) substantially reduced the incidence of AF in the PREDIMED trial. The PREDIMAR will test a similar intervention in secondary prevention. METHODS PREDIMAR is a multicenter, randomized, single-blind trial testing the effect of a MedDiet enriched with EVOO to reduce tachyarrhythmia relapses after AF ablation. The primary outcome is the recurrence of any sustained atrial tachyarrhythmia after ablation (excluding those occurring only during the first 3 months after ablation). The target final sample size is 720 patients (360 per group) recruited from 4 Spanish hospitals. A remote intervention, maintained for 2 years, is delivered to the active intervention group including periodic phone calls by a dietitian and free provision of EVOO. The control group will receive delayed intervention after trial completion. Routine electrocardiogram (ECG) and Holter ECG are performed, and a portable cardiac rhythm monitoring device is provided to be worn by participants during 15 months. RESULTS Recruitment started in March 2017. Up to July 2019, 609 patients were randomized (average inclusion rate: 5.3 patients/wk). Retention rates after 18 months are >94%. CONCLUSIONS If our hypothesis is confirmed, the utility of the MedDiet enriched with EVOO in slowing the progression of AF will be proven, preventing recurrences and potentially reducing complications.

Abstract
BACKGROUND Experimental and clinical evidence support the role of macrophage Toll-like receptor signaling in maternal anti-SSA/Ro-mediated congenital heart block (CHB). OBJECTIVES Hydroxychloroquine (HCQ), an orally administered Toll-like receptor antagonist widely used in lupus including during pregnancy, was evaluated for efficacy in reducing the historical 18% recurrence rate of CHB. METHODS This multicenter, open-label, single-arm, 2-stage clinical trial was designed using Simon's optimal approach. Anti-SSA/Ro-positive mothers with a previous pregnancy complicated by CHB were recruited (n = 19 Stage 1; n = 35 Stage 2). Patients received 400 mg daily of HCQ prior to completion of gestational week 10, which was maintained through pregnancy. The primary outcome was 2° or 3° CHB any time during pregnancy, and secondary outcomes included isolated endocardial fibroelastosis, 1° CHB at birth and skin rash. RESULTS By intention-to-treat (ITT) analysis, 4 of 54 evaluable pregnancies resulted in a primary outcome (7.4%; 90% confidence interval: 3.4% to 15.9%). Because 9 mothers took potentially confounding medications (fluorinated glucocorticoids and/or intravenous immunoglobulin) after enrollment but prior to a primary outcome, to evaluate HCQ alone, 9 additional mothers were recruited and followed the identical protocol. In the per-protocol analysis restricted to pregnancies exposed to HCQ alone, 4 of 54 (7.4%) fetuses developed a primary outcome as in the ITT. Secondary outcomes included mild endocardial fibroelastosis (n = 1) and cutaneous neonatal lupus (n = 4). CONCLUSIONS These prospective data support that HCQ significantly reduces the recurrence of CHB below the historical rate by >50%, suggesting that this drug should be prescribed for secondary prevention of fetal cardiac disease in anti-SSA/Ro-exposed pregnancies.

Abstract
OBJECTIVE To examine diabetes remission following a short-term intensive metabolic intervention combining lifestyle and glucose-lowering approaches. METHODS We conducted an open-label, randomized controlled trial in 154 patients with type 2 diabetes up to 8 years in duration on 0 to 2 glucose-lowering medications. Participants were randomized to (a) a 12-week intensive intervention comprising lifestyle approaches and treatment with insulin glargine, metformin, and dapagliflozin or (b) standard diabetes care. At 12 weeks, diabetes medications were discontinued in participants with hemoglobin A1c (HbA1C) < 7.3% (56 mmol/mol). Participants were then followed for diabetes relapse until 64 weeks. The primary outcome was complete or partial diabetes remission (HbA1C < 6.5% [48 mmol/mol] off chronic diabetes drugs) at 24 weeks. Main secondary outcomes were complete or partial diabetes remission at 36, 48, and 64 weeks. RESULTS The primary outcome was achieved in 19 (24.7%) intervention group participants and 13 (16.9%) control group participants at 24 weeks (relative risk [RR] 1.5; 95% confidence interval [CI], 0.8-2.7). The relative risks of remission at 36, 48, and 64 weeks were 2.4 (95% CI, 1.2-5.0), 2.1 (95% CI, 1.0-4.4), and 1.8 (95% CI, 0.7-4.7), respectively. In an exploratory analysis, the intervention reduced the hazard of diabetes relapse with overt hyperglycemia by 43% (hazard ratio 0.57; 95% CI, 0.39-0.81). CONCLUSIONS Our primary outcome of diabetes remission at 24 weeks was not statistically significantly different. However, our overall results suggest that some patients with early type 2 diabetes are able to achieve sustained diabetes remission following a short-term intensive intervention. Further studies are needed to optimize the combined therapeutic approach used.

Abstract
BACKGROUNDStatins have pleiotropic effects on lipid metabolism. The relationship between these effects and future cardiovascular events is unknown. We characterized the changes in lipids upon pravastatin treatment and defined the relationship with risk reduction for future cardiovascular events.METHODSPlasma lipids (n = 342) were measured in baseline and 1-year follow-up samples from a Long-Term Intervention with Pravastatin in Ischaemic Disease (LIPID) study subcohort (n = 4991). The associations of changes in lipids with treatment and cardiovascular outcomes were investigated using linear and Cox regression. The effect of treatment on future cardiovascular outcomes was examined by the relative risk reduction (RRR).RESULTSPravastatin treatment was associated with changes in 206 lipids. Species containing arachidonic acid were positively associated while phosphatidylinositol species were negatively associated with pravastatin treatment. The RRR from pravastatin treatment for cardiovascular events decreased from 23.5% to 16.6% after adjustment for clinical risk factors and change in LDL-cholesterol (LDL-C) and to 3.0% after further adjustment for the change in the lipid ratio PI(36:2)/PC(38:4). Change in PI(36:2)/PC(38:4) mediated 58% of the treatment effect. Stratification of patients into quartiles of change in PI(36:2)/PC(38:4) indicated no benefit of pravastatin in the fourth quartile.CONCLUSIONThe change in PI(36:2)/PC(38:4) predicted benefit from pravastatin, independent of change in LDL-C, demonstrating its potential as a biomarker for monitoring the clinical benefit of statin treatment in secondary prevention.TRIAL REGISTRATIONAustralian New Zealand Clinical Trials Registry identifier ACTRN12616000535471.FUNDINGBristol-Myers Squibb; NHMRC grants 211086, 358395, and 1029754; NHMRC program grant 1149987; NHMRC fellowship 108026; and the Operational Infrastructure Support Program of the Victorian government of Australia.

Abstract
Objective- Secondary prevention for recurrent myocardial infarction (MI) is one of the most important therapeutic goals in patients with old MI (OMI). Although statins are widely used for this purpose, there remains considerable residual risk even after LDL (low-density lipoprotein cholesterol) is well controlled by statins. Approach and Results- We examined clinical impacts of nHDL (nonhigh-density lipoprotein cholesterol) and its major components triglyceride and LDL as residual risks for acute MI recurrence, using the database of our CHART (Chronic Heart Failure Analysis and Registry in the Tohoku District)-2 Study, the largest-scale cohort study of cardiovascular patients in Japan. We enrolled 1843 consecutive old MI patients treated with statins (mean age 67.3 years, male 19.2%) in the CHART-2 Study. The incidence of recurrent acute MI during the median 8.6-year follow-up was compared among the groups divided by the levels of nHDL (<100, 100-129, and ≥130 mg/dL), LDL (<70, 70-99, and ≥100 mg/dL), triglyceride (<84, 84-149, and ≥150 mg/dL), and combination of LDL and triglyceride. Kaplan-Meier curves and multiple Cox proportional hazards models showed that higher levels of nHDL, but not LDL or triglyceride alone, were associated with higher incidence of recurrent acute MI. Furthermore, higher triglyceride levels were associated with higher incidence of recurrent MI in patients with LDL <100 mg/dL but not in those with LDL ≥100 mg/dL. Conclusions- These results indicate that management of residual risks for acute MI recurrence should include nHDL management considering both LDL and triglyceride in old MI patients under statin treatment.

Abstract
BACKGROUND & AIMS Endoscopic mucosal resection (EMR) with submucosal injection is an established method for removing colorectal polyps, although the en bloc resection rate decreases when polyp size exceeds 10 mm. Piecemeal resection increases local recurrence. Underwater EMR (UEMR) is an effective technique for removal of sessile colorectal polyps and we investigated whether it is superior to conventional EMR (CEMR). METHODS We conducted a multicenter randomized controlled trial at 5 institutions in Japan. Patients with endoscopically diagnosed, intermediate-size (10-20 mm) sessile colorectal lesions were randomly assigned to undergo UEMR or CEMR. Only the most proximal lesion was registered. The UEMR procedure included immersion of the entire lumen in water and snare resection of the lesion without submucosal injection of normal saline. We analyzed outcomes of 108 colorectal lesions in the UEMR group and 102 lesions in the CEMR group. R0 resection was defined as en bloc resection with a histologically confirmed negative resection margin. The primary endpoint was the difference in the R0 resection rates between groups. RESULTS The proportions of R0 resections were 69% (95% confidence interval [CI] 59%-77%) in the UEMR group vs 50% (95% CI 40%-60%) in the CEMR group (P = .011). The proportions of en bloc resections were 89% (95% CI 81%-94%) in the UEMR group vs 75% (95% CI 65%-83%) in the CEMR group (P = .007). There was no significant difference in median procedure time (165 vs 175 seconds) or proportions of patients with adverse events (2.8% in the UEMR group vs 2.0% in the CEMR group). CONCLUSIONS In a multicenter randomized controlled trial, we found that UEMR significantly increased the proportions of R0 resections for 10- to 20-mm sessile colorectal lesions without increasing adverse events or procedure time. Use of this procedure should be encouraged. Trials registry number: UMIN000018989.

Abstract
BACKGROUND Patients at increased cardiovascular (CV) risk, noticeably hypertensive patients, have multiple CV risk factors which may be treatment targets. LDL-cholesterol is one of such targets. Using the SPRINT cohort, studying the cardiovascular outcomes of hypertensive patients at increased CV risk, this post-hoc study aimed to assess the association of LDL-C with CV outcomes. METHODS Clinical outcomes were those defined in SPRINT a composite of various CV outcomes, all-cause mortality, and CV mortality. Association between LDL-C and the primary outcome was analyzed using survival regression adjusted on confounding factors (age, sex, body-mass index, active smoking status, eGFR-estimated kidney function, history of CV disease, Framingham risk score, SPRINT treatment arm (intensive or control), baseline high-density-lipoprotein-bound cholesterol, and co-treatments by aspirin and statins). RESULTS LDL-C was not associated with the primary outcome in the overall cohort (n = 9631). Among patients in secondary prevention (i.e. with a previous history of CV disease) (n = 1562), LDL-C was marginally associated with the incidence of the primary outcome (adjusted hazard-ratio 1.005 (95% CI = 1.002-1.009), p = 0.005 (per 1 mg/dl increase)) however, discrimination was poor with a ROC AUC of 0.54, p = 0.087. There was no association between LDL-C and the primary outcome in other subgroup analyses (those under statin or not, and those in primary prevention). CONCLUSION This post-hoc analysis of SPRINT indicates that LDL-C levels do not influence cardiovascular events over a period of 3 years in a large cohort of hypertensive patients at increased risk of cardiovascular events but without previous history of clinical cardiovascular disease other than stroke.

Abstract
BACKGROUND Appropriate dietary recommendations represent a key part of secondary prevention in cardiovascular disease (CVD). We evaluated the effectiveness of the implementation of a nutritional program on quality of diet, cardiovascular events, and death in patients with established CVD. METHODS In this open-label, multicenter trial conducted in 35 sites in Brazil, we randomly assigned (1:1) patients aged 45 years or older to receive either the BALANCE Program (experimental group) or conventional nutrition advice (control group). The BALANCE Program included a unique nutritional education strategy to implement recommendations from guidelines, adapted to the use of affordable and regional foods. Adherence to diet was evaluated by the modified Alternative Healthy Eating Index. The primary end point was a composite of all-cause mortality, cardiovascular death, cardiac arrest, myocardial infarction, stroke, myocardial revascularization, amputation, or hospitalization for unstable angina. Secondary end points included biochemical and anthropometric data, and blood pressure levels. RESULTS From March 5, 2013, to Abril 7, 2015, a total of 2534 eligible patients were randomly assigned to either the BALANCE Program group (n = 1,266) or the control group (n = 1,268) and were followed up for a median of 3.5 years. In total, 235 (9.3%) participants had been lost to follow-up. After 3 years of follow-up, mean modified Alternative Healthy Eating Index (scale 0-70) was only slightly higher in the BALANCE group versus the control group (26.2 ± 8.4 vs 24.7 ± 8.6, P < .01), mainly due to a 0.5-serving/d greater intake of fruits and of vegetables in the BALANCE group. Primary end point events occurred in 236 participants (18.8%) in the BALANCE group and in 207 participants (16.4%) in the control group (hazard ratio, 1.15; 95% CI 0.95-1.38; P = .15). Secondary end points did not differ between groups after follow-up. CONCLUSIONS The BALANCE Program only slightly improved adherence to a healthy diet in patients with established CVD and had no significant effect on the incidence of cardiovascular events or death.

Usefulness of Ezetimibe Versus Evolocumab as Add-On Therapy for Secondary Prevention of Cardiovascular Events in Patients With Type 2 Diabetes Mellitus.
Arbel, R, Hammerman, A, Azuri, J
The American journal of cardiology. 2019;(8):1273-1276
Abstract
Evolocumab and ezetimibe, were both proven to significantly reduce the incidence of major adverse cardiovascular events (MACE), in type 2 diabetes patients with atherosclerotic cardiovascular disease and low-density lipoprotein (LDL) cholesterol >70 mg/dl despite statin therapy. Providing evolocumab for all such patients may be a significant burden on healthcare systems. Therefore, we analyzed the treatment cost of ezetimibe versus evolocumab to prevent 1 MACE. We extracted the number needed to treat (NNT) with evolocumab or with ezetimibe for avoiding MACE from the published FOURIER and IMPROVE-IT trials respectively. Drug costs were based on 2018 US prices. Sensitivity and scenario analyses were performed to overcome variances in terms of population risk, efficacy of therapies, and costs. In FOURIER, the 1-year NNT for avoiding MACE with evolocumab was 104 (95% confidence intervals [CI] 66 to 235). In IMPROVE-IT, the 1-year NNT with ezetimibe was 124 (95% CI 73 to 288). The annual cost of evolocumab and ezetimibe is $6,540 and $88, respectively. Therefore, the cost to prevent 1 MACE in the FOURIER and IMPROVE-IT trials would have been $678,981 (95% CI $429,810 to $1,537,910,149) and $10,870 (95% CI $6,384 to $25,322), respectively. Ezetimibe was consistently a cost-saving strategy compared with evolocumab, in all analyses performed, except for the case where evolocumab price is significantly reduced and the branded ezetimibe is used. In conclusion, treatment with ezetimibe seems to be a major cost-saving strategy for preventing MACE in this patient population.
