Abstract
BACKGROUND In 2020, the WHO-approved Molbio Truenat platform and MTB assays to detect Mycobacterium tuberculosis complex (MTB) and resistance to rifampicin directly on sputum specimens. This primary health care center-based trial in Mozambique and Tanzania investigates the effect of Truenat platform/MTB assays (intervention arm) combined with rapid communication of results compared to standard of care on TB diagnosis and treatment initiation for microbiologically confirmed TB at 7 days from enrolment. METHODS The Tuberculosis Close the Gap, Increase Access, and Provide Adequate Therapy (TB-CAPT) CORE trial employs a pragmatic cluster randomized controlled design to evaluate the impact of a streamlined strategy for delivery of Truenat platform/MTB assays testing at primary health centers. Twenty-nine centers equipped with TB microscopy units were selected to participate in the trial. Among them, fifteen health centers were randomized to the intervention arm (which involves onsite molecular testing using Truenat platform/MTB assays, process process optimization to enable same-day TB diagnosis and treatment initiation, and feedback on Molbio platform performance) or the control arm (which follows routine care, including on-site sputum smear microscopy and the referral of sputum samples to off-site Xpert testing sites). The primary outcome of the study is the absolute number and proportion of participants with TB microbiological confirmation starting TB treatment within 7 days of their first visit. Secondary outcomes include time to bacteriological confirmation, health outcomes up to 60 days from first visit, as well as user preferences, direct cost, and productivity analyses. ETHICS AND DISSEMINATION TB-CAPT CORE trial has been approved by regulatory and ethical committees in Mozambique and Tanzania, as well as by each partner organization. Consent is informed and voluntary, and confidentiality of participants is maintained throughout. Study findings will be presented at scientific conferences and published in peer-reviewed international journals.

Abstract
BACKGROUND COVID-19 has significantly affected patients with cancer and revealed unanticipated challenges in securing optimal cancer care across different disciplines. The European Society for Medical Oncology COVID-19 and CAncer REgistry (ESMO-CoCARE) is an international, real-world database, collecting data on the natural history, management, and outcomes of patients with cancer and SARS-CoV-2 infection. METHODS This is the 2nd CoCARE analysis, jointly with Belgian (Belgian Society of Medical Oncology, BSMO) and Portuguese (Portuguese Society of Medical Oncology, PSMO) registries, with data from January 2020 to December 2021. The aim is to identify significant prognostic factors for COVID-19 hospitalization and mortality (primary outcomes), as well as intensive care unit admission and overall survival (OS) (secondary outcomes). Subgroup analyses by pandemic phase and vaccination status were carried out. RESULTS The cohort includes 3294 patients (CoCARE: 2049; BSMO: 928, all hospitalized by eligibility criteria; PSMO: 317), diagnosed in four distinct pandemic phases (January to May 2020: 36%; June to September 2020: 9%; October 2020 to February 2021: 41%; March to December 2021: 12%). COVID-19 hospitalization rate was 54% (CoCARE/PSMO), ICU admission 14%, and COVID-19 mortality 22% (all data). At a 6-month median follow-up, 1013 deaths were recorded with 73% 3-month OS rate. No significant change was observed in COVID-19 mortality among hospitalized patients across the four pandemic phases (30%-33%). Hospitalizations and ICU admission decreased significantly (from 78% to 34% and 16% to 10%, respectively). Among 1522 patients with known vaccination status at COVID-19 diagnosis, 70% were non-vaccinated, 24% had incomplete vaccination, and 7% complete vaccination. Complete vaccination had a protective effect on hospitalization (odds ratio = 0.24; 95% confidence interval [0.14-0.38]), ICU admission (odds ratio = 0.29 [0.09-0.94]), and OS (hazard ratio = 0.39 [0.20-0.76]). In multivariable analyses, COVID-19 hospitalization was associated with patient/cancer characteristics, the first pandemic phase, the presence of COVID-19-related symptoms or inflammatory biomarkers, whereas COVID-19 mortality was significantly higher in symptomatic patients, males, older age, ethnicity other than Asian/Caucasian, Eastern Cooperative Oncology Group performance status ≥2, body mass index <25, hematological malignancy, progressive disease versus no evident disease, and advanced cancer stage. CONCLUSIONS The updated CoCARE analysis, jointly with BSMO and PSMO, highlights factors that significantly affect COVID-19 outcomes, providing actionable clues for further reducing mortality.

Abstract
This study aims to compare multivariate calibration methods developed from data obtained by square wave anodic stripping voltammetry using a hanging mercury drop electrode for simultaneous determination of metals in cachaça, the following metals were studied: copper, zinc and cadmium. Multivariate calibration, partial least squares (PLS) and artificial neural network (ANN) methods were used in previous studies using other electrodes for this determination. In this new study, besides ANN and PLS, a hybrid model that combines PLS and NN, namely PLS-Neural was used. Also, samples of industrial cachaças were incorporated into the study in addition to artisanal samples. The quality of the methods was evaluated in terms of coefficient of determination (R2) and root mean square error of prediction (RMSEP). F test was used for comparing methods at confidence level of 95%. Based on these studies, it was found that although all methods show good results, the method employing neural networks stands out in the determination of copper in samples of cachaça. All methods proved to be fast and relatively low-cost, and they can be used for such analyses.

Abstract
Indigo Blue (IB) is a dye widely used by the textile sector for dyeing cellulose cotton fibers and jeans, being considered a recalcitrant substance, and therefore resistant to traditional treatments. Several methodologies are reported in the literature for the removal or degradation of dyes from the aqueous medium, among which photoelectrocatalysis stands out, which presents promising results in the degradation of dyes when a dimensionally stable anode (DSA) is used as a photoanode. In the present work, we sought to investigate the efficiency of a Ti/RuO2-TiO2 DSA modified with tin and tantalum for the degradation of Indigo Blue dye by photoelectrocatalysis. For this, electrodes were prepared by the thermal decomposition method and then a physical-chemical and electrochemical analysis of the material was carried out. The composition Ti/RuO2-TiO2-SnO2Ta2O5 (30:40:10:20) was compared to Ti/RuO2-TiO2 (30:70) in the photocatalysis, electrocatalysis, and photoelectrocatalysis tests. The photocatalysis was able to degrade only 63% of the IB at a concentration of 100 mg L-1 in 3 h, whereas the electrocatalysis and photoelectrocatalysis were able to degrade 100% of the IB at the same initial concentration in 65 and 60 min, respectively.

Introduction
The impact of acute infection by SARS-COV2 on the cardiovascular system has been previously reported in the literature, with a higher propensity in patients with more serious pattern of disease and pro-inflammatory status. Nevertheless, the long-term burden and sequels of COVID-19 on the cardiovascular system is still unknown.
Purpose
To evaluate the long-term impact of COVID-19 on left ventricular function in patients with severe clinical presentation requiring intensive care hospitalization.
Methods
This was a single-center observational, prospective study which included patients requiring admission to the Intensive Care Unit (ICU) due to COVID-19 infection from January to November 2020. All discharged patients were contacted to perform a clinical, electrocardiographic and echocardiographic evaluation and those who accepted were included on the protocol. Baseline and clinical characteristics were collected from clinical reports. For the global longitudinal strain (GLS) analysis all patients with significant wall motion abnormalities and valvular cardiopathy were excluded. Statistical analysis was performed with Mann-Whitney and a safety cut-off was established with ROC curve analysis.
Results
A total of 43 patients were included (mean age 64 ± 12, 67.4% males). During SARS-COV2 infection 49% presented with severe ARDS and 51% with moderate, 35% required invasive mechanical ventilation, 14% noninvasive mechanical ventilation and 52% with high nasal flow cannula. On the follow-up analysis, fatigue was the most reported in symptom (52% patients) and the majority did not present other signs or symptoms suggestive of heart failure, with the mean NT-proBNP of 49 ± 389 pg/dL. The standard ECG and echocardiogram did not show significant changes with a mean LVEF of 58 ± 7.8 and mean TAPSE of 21 ± 4. The strain analysis showed low value of GLS (mean GLS of -17.14 ± 2.36) for a reference cut-off of -18%, suggesting subclinical left ventricular dysfunction in this subset of patients with preserved ejection fraction. Maximum CPR values during ICU did not correlate either with the extent of disease evolvement in CT (p= NS) or ARDS severity (p= NS). Nevertheless, maximum CPR correlated significantly with GLS reduction (R = 0.44, p = 0.019). A CPR value higher than iger30mg/dL had 100% specificity for GLS reduction and a cut-off of 14gm/dL reported a sensitivity of 65% and specificity pf 75% for reduction in GLS.
Conclusion
In our study, we reported subclinical impairment in left ventricular function detected with global longitudinal strain after serious infection with SARS-COV2. The detected myocardial dysfunction was related with higher inflammatory as expressed by CPR values. Long-term monitoring of these patients should be undertaken in order to timely detect late complications. Abstract Figure.

Abstract
Abstract
Introduction
Atrial Fibrillation (AF) catheter ablation carries high bleeding and thromboembolic risks, requiring a detailed assessment of overall risk-benefit profile regarding antithrombotic strategy. Vitamin K Anticoagulant (VKA) and Non-Vitamin K Antagonist Oral Anticoagulant (NOAC) have been used in the latest years in this setting, and with different interruption protocols periprocedural. Our goal was to evaluate the rate of acute adverse events (AAE) and compare them according to antithrombotic strategy used periprocedural, in a real-world basis.
Methods
A single-center retrospective study, including adult patients admitted to first AF catheter ablation, from 2004 to 2020. Different antithrombotic strategies (anticoagulation with VKA uninterrupted, anticoagulation with NOAC uninterrupted, no therapy or antiaggregation/interrupted ACO) were compared concerning the rate of any clinically relevant AAE; the composite of major AAE (hemopericardium and stroke/transient ischemic attack [TIA]) and minor AAE associated with vascular access. Descriptive statistics and logistic regression were used to compare groups according to the antithrombotic strategy with an alpha level of 0.05.
Results
Among the 868 patients included (mean age 59±12 yo, 67,5% [n=586] men), pulmonary vein isolation was performed under uninterrupted anticoagulation in 640 (73,7%), of which 595 patients with NOAC (68,5%) and 45 with VKA (5,2%). AF was paroxysmal, persistent and long-standing persistent in 63,4% (n=550), 21,4% (n=185) and 15,4% (n=133) patients, respectively. Mean CHADS-VASc score was 1,86±1,48. Over time there was a shift in the distribution of the type of antithrombotic therapy used, consistent with changes in recommendations (Graph 1).
The composite outcome occurred in 6,8% (n=62), including hemopericardium in 1,8% (n=16), stroke/TIA in 0,7% (n=6) and events related to vascular access in 1,4% (n=13) [Table 1]. No anticoagulation therapy or antiaggregation/interrupted ACO was more associated to the outcome, driven by major AAE, although the difference did not meet statistical significance (p=0,06) [Table 1]. No difference was found between VKA and NOAC group. Additionally, there was no diference in the incidence of hemorrhagic AAE since the implementation of an uninterrupted anticoagulation strategy periprocedural.
Conclusion
In our population of patients submitted to AF catheter ablation, an uninterrupted anticoagulation strategy is associated with lower rate of AAE, either with VKA or NOAC. Our real-world results are reassuring of the benefit of an uninterrupted strategy, and consistent with recent controlled trials.

Introduction
Cavotricuspid isthmus ablation (CTA) is the 1st line therapy to accomplish rhythm control in typical atrial flutter (AFL). Several studies have shown that AFL is frequently associated with AF, which may be silent, posing the patient at risk of systemic embolism. Nowadays, there are no formal recommendations for OAC after CTA in patients with isolated AFL.
Aim
To determine the risk of MACE after CTA and compare: 1) the presence of concomitant AF, 2) concomitantly performing PVI and 3) persistence on OAC.
Methods
Single-center retrospective study of pts submitted to CTA between 2015 and 2019, comprising 3 groups: I – pts with lone AFL; II – patients with AFL and prior AF submitted to CTA only; and III – patients with AFL and prior AF submitted to PVI and CTA. Clinical records were analyzed to determine the occurrence of MACE - death (of CV or unknown cause), stroke, clinically relevant bleed or hospitalization due to HF or arrhythmic events. Long-term OAC was defined as its persistence over 18 months after CTA. Kaplan Meier survival curves were used to estimate the risk of events and the groups were compared using uni- and multivariate Cox regression analyses.
Results
A total of 476 pts (66 ± 12 years, 80% males) underwent CTA: group I – 284 pts (60%), II – 109 pts (23%) and III – 83 pts (17%). Baseline characteristics were similar between groups, except for age with group I pts being older (68 ± 12, 67 ± 11, 61 ± 11, p < 0.03). The mean baseline CHA2DS2VASc was 2.3 ± 1.5 and the median post-CTA follow-up was 2.8 year. The 1-, 3- and 5-years MACE risk was 7%, 21% and 32%, respectively and did not differ significantly between groups. OAC was suspended on the long-term in 105 pts (23%), at a mean of 241 days post-CTA. Suspension of OAC was significantly associated with lower MACE risk (HR: 0.26, 95%CI 0.12-0.56, p = 0.001). This effect was independent of the age and CHA2DS2VASc. The prognostic benefit of OAC suspension was driven by the group I and was not verified in patients with concomitant AF. In group I, withdraw of OAC (56 pts - 27%) was associated with a 70% relative risk reduction in the 5-year MACE risk (16% vs 43%, HR: 0.30, 95%CI 0.13-0.69, p = 0.005). In group I, OAC was suspended in patient who were younger (65 ± 11 vs. 69 ± 12, p = 0.002), had lower CHA2DS2VASc (1.9 ± 1.6 vs. 2.7 ± 1.4, p < 0.001) and less often had cerebral vascular disease (1% vs. 8%, p = 0.036), HF (14% vs. 38%, p = 0.001), ischemic cardiomyopathy (9% vs. 19%, p = 0.04) and HTN(61% vs. 75%, p = 0.019).
Conclusions
In pts with AFL submitted to CTA, the long-term risk of MACE is frighteningly high, even in the ones without prior documentation of concomitant AF. Pts with prior AF presenting at the electrophysiological procedure in typical AFL and submitted just to CTA were not significantly harmed, from a prognostic perspective. In pts with lone AFL submitted to successful CTA, it may be reasonable to suspend OAC within 18 months provided that the concomitant AF is carefully excluded. Abstract Figure.

BACKGROUND
Upgrade to resynchronization therapy (CRT) is common practice in Europe. However, patient selection remains a challenge. Data regarding predictors of response to upgrade is currently lacking.
AIM
To identify predictors of clinical response after upgrade to CRT.
METHODS
Single-center retrospective study of consecutive patients submitted to upgrade to CRT (2007-2018). Patients underwent clinical and echocardiographic (echo) evaluation at baseline, 6-months and 1-year. Major adverse cardiac events (MACE) included hospitalization for heart failure (HF) or all-cause mortality. Clinical response was defined as New York Heart Association (NYHA) class improvement without MACE in the 1st year of follow-up (FU). Left ventricle end-systolic volume reduction of >15% designated echo response. Multivariate logistic regression was performed to identify predictors of clinical response to CRT.
RESULTS
Fifty-six patients submitted to upgrade to CRT (80.4% male, mean age 70.0 ± 9.6 years) were included; 43 patients (78.2%) previously had a pacemaker and 12 (21.8%) had a defibrillator device. Most patients had non-ischemic HF (67.9%), with a mean baseline left ventricle (LV) ejection fraction of 27.9 ± 6.4%. Indications for upgrade were mainly pacemaker dependency or pacing-induced LV dysfunction (76.6%) and de novo left bundle branch block (23.4%).
Thirty-one (59.3%) patients were clinical responders. MACE occurred in 37.5% of patients; 28.6% were hospitalized for HF and 13% died during the 1st year of FU. Clinical responders had a lower rate of atrial fibrillation (AF) (46.9% vs. 53.1%, p=.025) and a higher rate of pacemaker rythm prior to upgrade (80.6% vs 47.6%, p=.013). Among responders, the previous device was more frequently a pacemaker (87.5% vs 61.9%, p=.029), and the new device a CRT-P (81.2% vs 54.5%, p=.035). HF etiology did not differ between responders and non-responders.
Multivariate analysis identified absence of AF (odds ratio [OR] 4.4, 95% confidence interval [CI] 1.1-17.6, p=.037), CRT-P (OR 5.7, 95% CI 1.3-25.8, p=.022) and quadripolar lead implant (OR 3.8, 95% CI 1.3-25.8, p=.024) as predictors of clinical response in upgraded patients.
CONCLUSIONS
In this cohort, absence of AF, implantation of CRT-P and use of a quadripolar lead predicted clinical response to upgrade to CRT. Larger studies are warranted to tailor selection of patients for upgrade procedures.

BACKGROUND
Resynchronization therapy (CRT) reduces morbidity and mortality in selected patients with heart failure with reduced ejection fraction (HFrEF). Patients that experience significant reverse remodelling and left ventricular (LV) ejection fraction (LVEF) improvement have been called "superresponders".
AIM
To describe a cohort of superresponders and identify predictors of superresponse to CRT.
METHODS
Single-center retrospective study of consecutive patients submitted to CRT implantation (2007-2018). Patients underwent echocardiographic (echo) assessment at baseline, 6-months and 1-year. Superresponse was defined as LVEF≥50% during the 1st year of follow-up (FU). Major adverse cardiac events (MACE) included heart failure hospitalization or all-cause mortality. Multivariate logistic regression was performed to identify predictors of superresponse. Survival analysis with Kaplan-Meier method and Log-rank test was performed to compare outcomes between superresponders and non-superresponders.
RESULTS
295 CRT patients (70.5% male, mean age 67 ± 11 years) were included. Fifty-nine (21.4%) patients were superresponders. Superresponders were more often female (42.4% vs 25.8%, p=.021), tended to be older (69.6 vs 66.7 years, p=.054) and had lower rates of coronary disease (17.2% vs 32.9%, p=.032), atrial fibrillation (20.3% vs 38.0%, p=.018), valve disease (13.6% vs 30.0%, p=.018) and chronic kidney disease (6.9% vs 26.0%, p=.003). Superresponders had higher rates of non-ischemic HF (88.1% vs 69.1%, p=.006) and were more often implanted with CRT-P (69.5% vs 37.8%, p<.001). HFrEF medication did not differ between groups.
Superresponders had lower baseline LV end-systolic volumes (115.5 vs 166.2 ml, p<.001) and N-terminal pro B-type natriuretic peptide (NT-proBNP) values (1232.6 vs 5252 pg/ml, p<.001). Baseline QRS duration did not differ (171.7 vs 171.3 ms, p=.883). During a median FU of 3 ± 5 years, there were no differences in terms of ventricular arrythmias (5.3% vs 6.8%, p=.913) or appropriate defibrillator therapies (1.8% vs 6.8%, p=.147) between groups. In addition to LVEF improvement (53.7% vs 35.3%, p<.001), superresponders also showed higher tricuspid annular plane systolic excursion values (22.1 vs 19.8 mm, p=.004) during FU. MACE occurred less frequently (Log-rank test, p=.003) and all-cause mortality (Log-rank test, p < 0.001) was lower in superresponders.
Multivariate analysis identified female gender (odds ratio [OR] 5.7, 95% confidence interval [CI] 1.03-31.73, p=.045), older age (OR 1.1, 95% CI 1.02-1.24, p=.017) and lower baseline NT-proBNP (OR 0.9, 95% CI 0.99-1.00, p=.011) as independent predictors of superresponse to CRT.
CONCLUSION
In superresponders, in addition to a significant improvement in LVEF, we observed an improvement in right ventricular function. As expected, MACE and all-cause mortality were lower. Female gender, older age and lower baseline NT-proBNP predicted super-response to CRT.

Abstract
Abstract
Background
Statins are highly effective in preventing major acute cardiovascular events in the setting of atherosclerotic arterial disease. On the other hand, given their antithrombotic and anti-inflammatory properties, statins may also attenuate patients' odds of developing venous thromboembolism (VTE). However, clinical studies have yielded variable estimates of this effect.
Purpose
To perform a meta-analysis designed to evaluate the extent to which statin use influences the rate of subsequent VTE events.
Methods
We systematically searched MEDLINE, Embase, Web of Science, Cochrane Library and Google Scholar for both randomized controlled trials (RCTs) and observational studies addressing the association between statins and VTE risk, published up until December 1, 2019. Manually reviewed references and key investigators interaction via e-mail correspondence were also data sources. RCTs comparing the effects of statin therapy with those of a placebo or no treatment were included, while interventional studies appraising different lipid-lowering pharmacological strategies were not. Observational studies encompassed both cohort and case-control designs. The primary endpoints were general VTE, deep vein thrombosis or pulmonary embolism. Patients with cancer, heart failure and chronic kidney disease (CKD) were further investigated separately. Study-specific relative risks (RRs) were pooled using generic inverse variance outcome meta-analytic technique with a random-effects model.
Results
23 RCTs comprising 118.464 participants, 12 cohort studies encompassing 2.881.184 patients and 9 case-control studies including 354.367 patients were regarded as eligible for quantitative evaluation. Specifically, 5 observational studies comprising 9.656 cancer patients, 3 studies encompassing 9.693 heart failure patients and 4 studies including 4.353 CKD patients were gathered. In RCTs, statin therapy was proven slightly superior to placebo or no treatment in lowering VTE incidence (RR 0.85, 95% CI 0.73–0.99, p=0.04, i2=14%). Observational studies were found to corroborate this effect, with statin treatment resulting in VTE risk reduction overall (RR 0.72, 95% CI 0.64–0.81, p<0.001, i2=84%) and in both cohort (RR 0.86, 95% CI 0.83–0.90, p<0.001, i2=85%) and case-control (RR 0.68, 95% CI 0.57–0.82, p<0.001, i2=80%) designs. This positive effect held true in cancer patients (RR 0.56, 95% CI 0.33–0.95, p=0.03, i2=78%), but not in those with heart failure (RR 0.7, 95% CI 0.42–1.16, p=0.17, i2=2%) and CKD (RR 1.04, 95% CI 0.67–1.60, p=0.87, i2=0%).
Conclusion
Currently available evidence suggests that statins significantly reduce patients' odds of developing VTE. Given their favorable safety profile and low cost, statin treatment should now be considered in high-risk individuals, particularly in those with cancer.

Abstract
Abstract
Background
Upgrade to resynchronization therapy (CRT) from conventional pacemaker (P) or defibrillator (D) is common practice in Europe. However, guidelines (GL) are discordant: Pacing GL give a class I recommendation, while Heart Failure (HF) GL provide a class IIb indication. Previous studies suggested worse outcomes in upgraded patients (pts).
Aim
To compare response rate and clinical outcomes in a cohort of pts receiving de novo or upgrade to CRT.
Methods
Single-center retrospective study of consecutive pts submitted to CRT implantation (2007–2017). Major adverse cardiac events (MACE) included HF hospitalization (HHF) or all-cause mortality. Clinical response was defined as New York Heart Association class improvement without MACE in the first year of follow-up (FU). Left ventricle end-systolic volume reduction of >15% denoted echocardiographic (echo) response. Survival analysis with Kaplan-Meier method and Log-rank test was performed. Propensity-score matching (PSM) analysis was made to adjust for possible confounder variables.
Results
230 CRT recipients (70.9% male, mean age 67±11 years, 71.5% non-ischemic cardiomyopathy, 39.6% CRT-P) were included, of whom 46 (20%) underwent an upgrade. Upgraded pts were older (69.8 vs 65.9 years, p=0.015), with higher rates of permanent atrial fibrillation (37.0% vs 12.7%, p=0.001), moderate to severe valve disease (45.7% vs 22.3%, p=0.002), chronic kidney disease (37.0% vs 17.2%, p=0.005) and treatment with mineralocorticoid receptor antagonists (79.1% vs 52.0%, p=0.002). They were more likely to receive CRT-P (65.2% vs 33.2%, p<0.001) and CRT-D were more often implanted for secondary prevention (60.0% vs 17.9%, p=0.001). No differences emerged in procedural complications, clinical (74.4% vs 71.4%, p=0.712) or echo (66.7% vs 69.7%, p=0.822) response rates.
During a median FU of 3±4 years, all-cause mortality was similar among groups (Log Rank test, p=0.522, unadjusted hazard ratio [HR] 1.25, confidence interval [CI] 95% 0.62–2.49, p=0.534). There was a statistical tendency for higher MACE rate in the upgrade group (Log Rank test, p=0.064, HR 1.66, CI 95% 0.95–2,91, p=0.076). No differences were found in lead dislodgement (10.9% vs 7.1%, p=0.368) or endocarditis (2.2% vs 4.3%, p=0.692) rates.
PSM analysis identified 88 matched pairs (46 upgrade/42 de novo pts). In this cohort, all-cause mortality (Log Rank test, p=0.77, HR 0.89, CI 95% 0.39–2.03, p=0.78) and MACE (Log Rank test, p=0.36, HR 1.38, CI 95% 0.68–2.81, p=0.37) were comparable between groups [graph no. 1].
Conclusion
Upgrade to CRT was similar to de novo implantation in terms of complications and clinical and echo response, in this cohort. The risk for MACE and mortality was also comparable.

Abstract
Abstract
Background
Among all subsets of coronary artery lesions, bifurcations stand out due to high incidence, demanding percutaneous interventions (PCIs) and poor outcomes. Amid the different PCI strategies, the provisional (PS) approach is generally recommended over 2-stent (TS) techniques, but this paradigm has been challenged.
Purpose
To compare PS with TS for PCI of coronary bifurcation lesions, concerning procedural aspects and both immediate and long-term patient outcomes.
Methods
Retrospective study encompassing patients consecutively referred to a tertiary interventional cardiology unit for coronary angiography, who were found to have at least 1 native bifurcation lesion. According to operator experience and angiographic features, patients were managed with PS or/(and) TS. Procedural aspects regarding radiological variables, angiographic success and immediate complications were reviewed, as were in-hospital outcomes. Besides, clinical follow-up, by clinic appointment or telephone calling, was performed targeting stent failure, target vessel revascularization (TVR), acute coronary syndromes (ACS), heart failure and mortality.
Results
From January 2010 to June 2017, 404 patients with 433 bifurcation lesions were included. Median age was 70 (62–77) years and 25.3% were female. Median follow-up was 2 (1–3) years. Chronic angina was the dominant PCI context (61.3%) with 9.7% presenting with ST-segment elevation myocardial infarction (MI). Medina class 1,1,1 was documented in 54.1% and 64.9% of lesions were hailed as true bifurcations. 303 patients underwent PS, whereas 67 were managed with TS, with TAP (43.3%) and mini-crush (34.3%) as the leading techniques. True bifurcations were more frequently approached with TS (p<0.001), whereas PCI context did not influence procedure selection. Fluoroscopy time (p<0.001), radiation dose (p=0.003) and contrast volume (p=0.009) were higher in the TS subgroup. OCT guidance (p=0.039) was also more common with TS. Angiographic success was uniformly high (95.1% for PS and 97% for TS), while procedural complications, including iatrogenic coronary dissections (7.4%, mostly minor) and slow-reflow (3.5%), were homogenously low. Acute kidney injury and type 4a MI occurred in 14.5% and 32.3%, respectively, also with no difference between groups. As for long-term outcomes, stent failure, encompassing both stent thrombosis (1 event) and restenosis (4.2%), occurred more often with TS (p=0.046), with ACS events (9.5%) following the same trend (p=0.08). In turn, rates of TVR (12.5%), heart failure hospitalization (6.2%) and mortality, regardless of its cardiovascular nature, were similar.
Conclusion
PS outperforms TS during follow-up, particularly due to lower stent failure odds. Thus, this study further supports the concept of PS as the standard approach for coronary bifurcation lesions.

Abstract
Abstract
Background
Historically, women (W) with acute coronary syndrome (ACS) have worse outcomes compared with men (M). This fact may occur due to gender-specific differences in the presentation and management of patients (P), which were mainly observed in studies dealing with ST-segment elevation infarction (STEMI). There seems to be a gap of knowledge in gender-specific differences in non- ST elevation myocardial infarction (NSTEMI) and unstable angina (UA).
Purpose
Assess gender-specific differences in presentation, treatment and outcomes in NSTEMI and UA patients.
Methods
A retrospective cohort study from consecutive ACS patients enrolled in a multicentre national registry from October 2010 to December 2018 was conducted, identifying 11394 P admitted with NSTEMI or UA. Demographic, clinical and treatment variables were compared between male gender and female gender P.
A Cox multivariate regression was performed to evaluate predictor factors of stablished endpoints: mortality at 1-year (1y) and cardiovascular (CV) hospitalization at 1-year.
Results
A total 11394 P were included, 8145 M (71.5%) and 3249 W (28.5%), mean age of 68±13. W, comparing with M, had higher age (72±12 vs 66±13, p=0.001), higher prevalence of hypertension (85% vs 72%, p=0.001) and diabetes (41% vs 34%, p=0.001) and longer time from symptoms to hospital admission (360 minutes vs 297 minutes, p=0.001). Chest pain was less frequent as first symptom in W (85.6% vs 91.3%, p=0.001). In medical treatment, W had higher chance of not having administration of a loading dose of P2Y12 inhibitor (22.1% vs 18.1, p=0.001) and of being medicated with clopidogrel (85.7% vs 82.1%, p=0.002). At discharge, W were less frequently medicated with an angiotensin-converting enzyme (ACE) inhibitor or an angiotensin II receptor blocker (82.6% vs 84.4, p=0.028). Coronary angiography was less frequently performed in W (77.3% vs 85.7%, p=0.001). Coronary artery disease was less frequently found in the female gender (12.4% vs 4.8%, p=0.001).
In-hospital mortality was higher in W (2.9% vs 2.1%), but in the multivariate analysis the female gender was not an independent predictor of in-hospital mortality (OR 1.05 [0.67- 1.65], p=0.823). 1-year mortality was higher in W (9.2% vs 7.3%) and 1-year CV hospitalization was higher in M (16.8% vs 14.4%). After adjusting for covariates in Cox regression analysis, difference was still significant for mortality (HR= 1.274 [1.038 - 1.564], p=0.02) and hospitalization (HR = 0.852 [0.726- 0.998], p=0.047).
Conclusion
In this NSTEMI and UA cohort, there are important gender-specific differences in comorbidities, diagnosis, management and outcomes. Gender was an independent predictor of 1-year mortality and 1-year CV hospitalization, but not an independent predictor for in-hospital mortality.

Abstract
Abstract
Background
Currently available pharmacological options for rhythm control in atrial fibrillation (AF) are overshadowed by suboptimal efficacy and both frequent and potentially severe adverse events. Recent studies have added evidence to the hypothesis that ranolazine might exert antiarrhythmic effects, particularly in atrial tachyarrhythmias.
Purpose
To perform a systematic review with meta-analysis in order to ascertain the potential role of ranolazine in the management of AF.
Methods
We systematically searched MEDLINE, Embase and Scopus for randomized controlled trials (RCTs) and cohort studies addressing the association between ranolazine and AF outcomes, published up until December 1, 2019. The primary endpoint was incidence of AF, which was evaluated under a ranolazine versus placebo design. In this regard, patients in the setting of postcardiac surgery were further investigated separately. Secondary endpoints included AF cardioversion outcomes, which were addressed through comparison between ranolazine plus amiodarone and amiodarone alone for proportional efficacy and temporal requirements (time-to-cardioversion). The latter analysis was also undertaken in a dose-sensitive fashion (≤1000mg vs. 1500mg of ranolazine). Tertiary endpoints covered AF burden and episodes, in paroxysmal AF patients, and safety outcomes, namely death, QTc interval prolongation and hypotension. Study-specific odds ratios (ORs) were pooled using meta-analytic techniques with a random-effects model.
Results
A total of 10 RCTs comprising 8.109 participants and 3 cohort studies encompassing 37.112 patients were regarded as eligible for evaluation. Ranolazine was found to attenuate patients' odds of developing AF (OR 0.53, 95% CI: 0.41–0.69, p<0.001, i2=58%). This effect held true, with an even larger effect size, in the context of post-cardiac surgery (OR 0.34, 95% CI: 0.16–0.72, p=0.005, i2=64%). Ranolazine increased the chances of successful AF cardioversion when added to amiodarone over amiodarone alone (OR 6.67, 95% CI: 1.49–29.89, p=0.01, i2=76%), while significantly reducing time-to-cardioversion [SMD 9.54h, 95% CI: −13.3–5.75, p<0.001, i2=99%]. Interestingly, cardioversion was faster with ≤1000mg of ranolazine (SMD −13.16h, 95% CI: −15.07–11.25, p<0.001, i2=95%) than with 1500mg (SMD −3.57h, 95% CI: −5.06–2.08, p<0.001, i2=23%). In paroxysmal AF, ranolazine was also proved to significantly reduce both AF burden and episodes. There were no safety signals regarding mortality odds, QTc interval prolongation (mostly clinically insignificant) and hypotension (mostly transitory).
Conclusion
Current evidence suggests that ranolazine provides an effective and safe option for a chemical rhythm control strategy in AF management, a field in which medical breakthroughs are desperately needed.
