Abstract Introduction Guidelines recommend endoscopy with biopsies to stratify patients with gastric premalignant lesions (GPL) to high and low progression risk. High-risk patients are recommended to undergo surveillance. We aimed to assess the accuracy of guideline recommendations to identify low-risk patients, who can safely be discharged from surveillance. Methods This study includes patients with GPL. Patients underwent at least two endoscopies with an interval of 1–6 years. Patients were defined ‘low risk’ if they fulfilled requirements for discharge, and ‘high risk’ if they fulfilled requirements for surveillance, according to European guidelines (MAPS-2012, updated MAPS-2019, BSG). Patients defined ‘low risk’ with progression of disease during follow-up (FU) were considered ‘misclassified’ as low risk. Results 334 patients (median age 60 years IQR11; 48.7% male) were included and followed for a median of 48 months. At baseline, 181/334 (54%) patients were defined low risk. Of these, 32.6% were ‘misclassified’, showing progression of disease during FU. If MAPS-2019 were followed, 169/334 (51%) patients were defined low risk, of which 32.5% were ‘misclassified’. If BSG were followed, 174/334 (51%) patients were defined low risk, of which 32.2% were ‘misclassified’. Seven patients developed gastric cancer (GC) or dysplasia, four patients were ‘misclassified’ based on MAPS-2012 and three on MAPS-2019 and BSG. By performing one additional endoscopy 72.9% (95% CI 62.4–83.3) of high-risk patients and all patients who developed GC or dysplasia were identified. Conclusion One-third of patients that would have been discharged from GC surveillance, appeared to be ‘misclassified’ as low risk. One additional endoscopy will reduce this risk by 70%.

Although extensive advancements have been made in treatment against hepatocellular carcinoma (HCC), the prognosis of HCC patients remains unsatisfied. It is now clearly established that extensive epigenetic changes act as a driver in human tumors. This study exploits HCC epigenetic deregulation to define a novel prognostic model for monitoring the progression of HCC. We analyzed the genome-wide DNA methylation profile of 374 primary tumor specimens using the Illumina 450 K array data from The Cancer Genome Atlas. We initially used a novel combination of Machine Learning algorithms (Recursive Features Selection, Boruta) to capture early tumor progression features. The subsets of probes obtained were used to train and validate Random Forest models to predict a Progression Free Survival greater or less than 6 months. The model based on 34 epigenetic probes showed the best performance, scoring 0.80 accuracy and 0.51 Matthews Correlation Coefficient on testset. Then, we generated and validated a progression signature based on 4 methylation probes capable of stratifying HCC patients at high and low risk of progression. Survival analysis showed that high risk patients are characterized by a poorer progression free survival compared to low risk patients. Moreover, decision curve analysis confirmed the strength of this predictive tool over conventional clinical parameters. Functional enrichment analysis highlighted that high risk patients differentiated themselves by the upregulation of proliferative pathways. Ultimately, we propose the oncogenic MCM2 gene as a methylation-driven gene of which the representative epigenetic markers could serve both as predictive and prognostic markers. Briefly, our work provides several potential HCC progression epigenetic biomarkers as well as a new signature that may enhance patients surveillance and advances in personalized treatment.

Abstract Background High-risk patients with multivessel disease (MVD) including a complex stenosis of the left anterior descending coronary may not be ideal candidates for guideline compliant therapy by coronary artery bypass grafting (CABG) regarding invasiveness and perioperative complications. However, they may benefit from minimally invasive direct coronary artery bypass (MIDCAB) grafting and hybrid revascularization (HCR). Methods A logistic European system for cardiac operative risk evaluation score (logES) >10% defined high risk. In high-risk patients with MVD undergoing MIDCAB or HCR, the incidence of major adverse cardiac and cerebrovascular events (MACCEs) after 30 days and during midterm follow-up was evaluated. Results Out of 1,250 patients undergoing MIDCAB at our institution between 1998 and 2015, 78 patients (logES: 18.5%; age, 76.7 ± 8.6 years) met the inclusion criteria. During the first 30 days, mortality and rate of MACCE were 9.0%; early mortality was two-fold overestimated by logES. Complete revascularization as scheduled was finally achieved in 64 patients (82.1%). Median follow-up time reached 3.4 (1.2–6.5) years with a median survival time of 4.7 years. Survival after 1, 3, and 5 years was 77, 62, and 48%. Conclusion In high-risk patients with MVD, MIDCAB is associated with acceptable early outcome which is better than predicted by logES. Taking the high-risk profile into consideration, midterm follow-up showed satisfying results, although scheduled HCR was not realized in a relevant proportion. In selected cases of MVD, MIDCAB presents an acceptable alternative for high-risk patients.

ObjectiveTo investigate to what extent patients with inflammatory arthritis (IA) follow recommendations given in a secondary care nurse-led cardiovascular (CV) risk screening consultation to consult their general practitioner (GP) to reduce their CV risk and whether their socioeconomic status (SES) affects adherence.MethodsAdults with IA who had participated in a secondary care screening consultation from July 2012 to July 2015, based on the EULAR recommendations, were identified. Patients were considered to have high CV risk if they had risk Systematic COronary Risk Evaluation (SCORE) ≥5%, according to the European SCORE model or systolic blood pressure ≥145 mmHg, total cholesterol ≥8 mmol/L, LDL cholesterol ≥5 mmol/L, HbA1c ≥42 mmol/mol or fasting glucose ≥6 mmol/L. The primary outcome was a consultation with their GP and at least one action focusing on CV risk factors within 6 weeks after the screening consultation.ResultsThe study comprised 1265 patients, aged 18–85 years. Of these, 336/447 (75%) of the high-risk patients and 580/819 (71%) of the low-risk patients had a GP consultation. 127/336 (38%) of high-risk patients and 160/580 (28%) of low-risk patients received relevant actions related to their CV risk, for example, blood pressure home measurement or prescription for statins, antihypertensives or antidiabetics. Education ≥10 years increased the odds for non-adherence (OR 0.58, 95% CI 0.0.37 to 0.92, p=0.02).Conclusions75% of the high-risk patients consulted their GP after the secondary care CV risk screening, and 38% of these received an action relevant for their CV risk. Higher education decreased adherence.

Abstract Background Restrictions on face-to-face contact, due to COVID-19, led to a rapid adoption of technology to remotely deliver cardiac rehabilitation (CR). Some technologies, including Active+me, were used without knowing their benefits. We assessed changes in patient activation measure (PAM) in patients participating in routine CR, using Active+me. We also investigated changes in PAM among low, moderate, and high risk patients, changes in cardiovascular risk factors, and explored patient and healthcare professional experiences of using Active+me. Methods Patients received standard CR education and an exercise prescription. Active+me was used to monitor patient health, progress towards goals, and provide additional lifestyle support. Patients accessed Active+me through a smart-device application which synchronised to telemetry enabled scales, blood pressure monitors, pulse oximeter, and activity trackers. Changes in PAM score following CR were calculated. Sub-group analysis was conducted on patients at high, moderate, and low risk of exercise induced cardiovascular events. Qualitative interviews explored the acceptability of Active+me. Results Forty-six patients were recruited (Age: 60.4 ± 10.9 years; BMI: 27.9 ± 5.0 kg.m2; 78.3% male). PAM scores increased from 65.5 (range: 51.0 to 100.0) to 70.2 (range: 40.7 to 100.0; P = 0.039). PAM scores of high risk patients increased from 61.9 (range: 53.0 to 91.0) to 75.0 (range: 58.1 to 100.0; P = 0.044). The PAM scores of moderate and low risk patients did not change. Resting systolic blood pressure decreased from 125 mmHg (95% CI: 120 to 130 mmHg) to 119 mmHg (95% CI: 115 to 122 mmHg; P = 0.023) and waist circumference measurements decreased from 92.8 cm (95% CI: 82.6 to 102.9 cm) to 85.3 cm (95% CI 79.1 to 96.2 cm; P = 0.026). Self-reported physical activity levels increased from 1557.5 MET-minutes (range: 245.0 to 5355.0 MET-minutes) to 3363.2 MET-minutes (range: 105.0 to 12,360.0 MET-minutes; P < 0.001). Active+me was acceptable to patients and healthcare professionals. Conclusion Participation in standard CR, with Active+me, is associated with increased patient skill, knowledge, and confidence to manage their condition. Active+me may be an appropriate platform to support CR delivery when patients cannot be seen face-to-face. Trial registration As this was not a clinical trial, the study was not registered in a trial registry.

Objective Aortic valve replacement in minimally invasive approach has shown to improve clinical outcomes even with a prolonged cardiopulmonary bypass and aortic cross-clamp (ACC) time. Sutureless aortic valve implantation may ideally shorten operative time. We describe our initial experience with the sutureless 3f Enable (Medtronic, Inc, ATS Medical, Minneapolis, MN USA) aortic bioprosthesis implanted in minimally invasive approach in high-risk patients. Methods Between May 2010 and May 2011, thirteen patients with severe aortic stenosis underwent aortic valve replacement with the 3f Enable bioprosthesis through an upper V-type ministernotomy interrupted at the second intercostal space. The mean ± SD age was 77 ± 3.9 years (range, 72–83 years), 10 patients were women, and the mean ± SD logistic EuroSCORE was 15% ± 13.5%. Echocardiography was performed preoperatively, at postoperative day 1, at discharge, and at follow-up. Clinical data, adverse events, and patient outcomes were recorded retrospectively. The median follow-up time was 4 months (interquartile range, 2–10 months). Results Most of the implanted valves were 21 mm in diameter (19–25 mm). The CPB and ACC times were 100.2 ± 25.3 and 66.4 ± 18.6 minutes. At short-term follow-up, the mean ± SD pressure gradient was 14 ± 4.9 mm Hg; one patient showed trivial paravalvular leakage. No patients died during hospital stay or at follow-up. Conclusions The 3f Enable sutureless bioprosthesis implanted in minimally invasive approach through an upper V-type ministernotomy is a feasible, safe, and reproducible procedure. Hemodynamic and clinical data are promising. This innovative approach might be considered as an alternative in high-risk patients. Reduction of CPB and ACC time is possible with increasing of experience and sutureless evolution of actual technology.

Abstract Background Following Myocardial Infarction (MI), patients are at increased risk for recurrent cardiovascular events, particularly during the immediate period. Yet some patients are at higher risk than others, owing to their clinical characteristics and comorbidities, these high-risk patients are less often treated with guideline-recommended therapies. Aim To examine temporal trends in treatment and outcomes of patients with MI according to the TIMI risk score for secondary prevention (TRS2°P), a recently validated risk stratification tool. Methods A retrospective cohort study of patients with an acute MI, who underwent percutaneous coronary intervention and were discharged alive between 2004–2016. Temporal trends were examined in the early (2004–2010) and late (2011–2016) time-periods. Patients were stratified by the TRS2°P to a low (≤1), intermediate (2) or high-risk group (≥3). Clinical outcomes included 30-day MACE (death, MI, target vessel revascularization, coronary artery bypass grafting, unstable angina or stroke) and 1-year mortality. Results Among 4921 patients, 31% were low-risk, 27% intermediate-risk and 42% high-risk. Compared to low and intermediate-risk patients, high-risk patients were older, more commonly female, and had more comorbidities such as hypertension, diabetes, peripheral vascular disease, and chronic kidney disease. They presented more often with non ST elevation MI and 3-vessel disease. High-risk patients were less likely to receive drug eluting stents and potent anti-platelet drugs, among other guideline-recommended therapies. Evidently, they experienced higher 30-day MACE (8.1% vs. 3.9% and 2.1% in intermediate and low-risk, respectively, P<0.001) and 1-year mortality (10.4% vs. 3.9% and 1.1% in intermediate and low-risk, respectively, P<0.001). During time, comparing the early to the late-period, the use of potent antiplatelets and statins increased among the entire cohort (P<0.001). However, only the high-risk group demonstrated a significantly lower 30-day MACE (P=0.001). During time, there were no differences in 1-year mortality rate among all risk categories. Temporal trends in 30-day MACE by TRS2°P Conclusion Despite a better application of guideline-recommended therapies, high-risk patients after MI are still relatively undertreated. Nevertheless, they demonstrated the most notable improvement in outcomes over time.
