© 2019 The Author(s). Background: Spontaneous pregnancy loss and implantation failure after assisted reproductive technologies (ART) are very common occurrences. Although 50-60% of all cases remains unexplained, various predisposing factors, including thrombophilias, have been identified. Thus, the potential benefit of a prophylaxis with low-molecular-weight heparins in improving outcomes has been often investigated over the years. However, the majority of studies are observational and results from randomized clinical trials (RCTs) are inconclusive, probably due to heterogeneity and limited sample size. To cover these unmet needs and to have further data mainly based on the real-life clinical management, we designed these multicenter registries. Methods: OTTILIA (Observational sTudy on antiThrombotic prevention in thrombophILIA and pregnancy loss) and FIRST (recurrent Failures in assIsted Reproductive Techniques) registries are two prospective, multicenter, observational studies to evaluate pregnancy or ART outcomes in consecutive women with previous reproductive failures after spontaneous or assisted conception, respectively. All enrolled women are observed from their first visit after positive pregnancy test (OTTILIA) or before commencing a new ART cycle (FIRST) until the end of pregnancy or ART procedure (negative pregnancy test/end of pregnancy, if successful cycle), respectively. Data are collected by means of questionnaires and recorded in a central database. Follow-up investigations are performed during hospital stay, routine clinical follow-up visits or telephone interviews. Primary outcome is live birth rate in the OTTILIA register and clinical pregnancy rate in the FIRST. Discussion: Although RCTs are the 'gold standard' for evaluating treatment outcomes, we believe that our registries represent a valid alternative in improving knowledge on mechanisms involved in reproductive failures and supporting future clinical decisions. Trial registration: NCT 02385461, retrospectively registered 5 March 2015 (OTTILIA); NCT 02685800, registered 10 February 2016 (FIRST).

© 2018, The Author(s). Introduction: Trimetazidine (TMZ) was shown to reduce angina symptoms and increase the exercise capacity in stable angina (SA) patients. A new formulation allowing a once-daily (od) dosage could improve patients’ satisfaction and adherence. Methods: ODA was a 3-month, observational, multicenter, prospective Russian study in SA patients with persistent symptoms despite therapy. Angina attack frequency, short-acting nitrate (SAN) consumption, adherence to antianginal medications, and overall efficacy and tolerability of TMZ 80 mg od were assessed in a real-world setting. Results: A total of 3066 patients were included (mean age 62.8, 48% male). After 3 months, TMZ 80 mg od treatment led to a significant (p < 0.001) decrease in angina attack frequency (from 4.7 ± 3.5 to 0.9 ± 1.3/week) and SAN use (from 4.5 ± 3.9 to 0.7 ± 1.3/week). Overall tolerability and effectiveness were rated as “very good” by the majority of physicians. Medication adherence improved significantly, with good adherence reported by 56% of patients (vs. 24% at baseline, p < 0.0001) and non-adherence by 3% (vs. 36% at baseline, p < 0.0001) at month 3. Patient satisfaction with TMZ od was 9.5 [on a scale of 1 to 10 (very satisfied)]. Patients reported improved physical activity: more patients reported no limitations (15% vs. 1% at baseline p < 0.01), slight limitation (46% vs. 5% at baseline, p < 0.001) or moderate limitation (30% vs. 23%, p < 0.01) and fewer patients reported substantial limitation (8% vs. 52% at baseline, p < 0.001) or very marked reduction (1% vs. 19% at baseline, p < 0.01) at month 3. Conclusion: In this prospective, observational study, TMZ 80 mg od effectively reduced angina attacks and SAN consumption, improved physical activity and adherence and was well tolerated in chronic SA patients.

© 2018, The Author(s). Introduction: Trimetazidine (TMZ) has been shown to reduce angina symptoms and to increase exercise capacity in randomized clinical trials, but more extensive data would be useful to assess its effects in real-world clinical practice and in patients with different durations of disease. Methods: CHOICE-2 was a Russian, multicenter, 6-month, open-label, prospective observational study that assessed the effect of adding TMZ modified release 35 mg bid to antianginal treatment in a real-world setting. The present analysis of CHOICE-2 results explored the effects of adding TMZ to background antianginal therapies with regard to the duration of stable angina. Results: A total of 741 patients with known durations of disease were divided into four groups according to stable angina pectoris (AP) duration, ranging from less than 1 year to more than 9 years. Addition of TMZ led to a significant decrease in the frequency of angina attacks and in the use of short-acting nitrates in all groups. In patients with recently diagnosed angina (AP duration < 1 year), the average number of angina attacks per week decreased significantly from 3.75 ± 4.63 to 0.67 ± 1.51 and in those with advanced disease (AP duration > 9 years) from 5.63 ± 5.24 to 1.32 ± 2.07. Angina-free walking distance also improved significantly. Addition of TMZ also improved patient well-being. Results were achieved rapidly (within 2 weeks), were maintained over 6 months, and were obtained in all patient groups regardless of angina duration. Conclusion: TMZ added to other antianginal therapies proved to be effective for reducing angina attacks and short-acting nitrate use, increasing angina-free walking distance, and improving patient well-being in a real-life setting, irrespective of angina duration, including patients with recently diagnosed angina. This provides an opportunity for intensification of treatment early on in the disease process, with the aim of decreasing angina burden and improving patient quality of life. Funding: Servier.

Aim: To investigate determinants of change in glycated haemoglobin (HbA1c) in patients with type 2 diabetes mellitus (T2DM) at 6 months after initiating uninterrupted second-line glucose-lowering therapies. Materials and Methods: This cohort study utilized retrospective data from 10 256 patients with T2DM who initiated second-line glucose-lowering therapy (switch from or add-on to metformin) between 2011 and 2014 in Germany and the UK. Effects of pre-specified patient characteristics on 6-month HbA1c changes were assessed using analysis of covariance. Results: Patients had a mean (standard error [SE]) baseline HbA1c of 8.68% (0.02); 28.5% of patients discontinued metformin and switched to an alternative therapy and the remainder initiated add-on therapy. Mean (SE) unadjusted 6-month HbA1c change was −1.27% (0.02). When adjusted for baseline HbA1c, 6-month changes depended markedly on the magnitude of the baseline HbA1c (HbA1c <9%, −0.45% per unit increase in HbA1c; HbA1c ≥9%, −0.87% per unit increase in HbA1c). Adjusted mean 6-month HbA1c reductions showed slight treatment differences (range, 0.92–1.09%; P <.001). Greater reductions in HbA1c were associated with second-line treatment initiation within 6 months of T2DM diagnosis (1.36% vs 1.03% [P <.001]) and advanced age (≥70 years, 1.13%; <70 years, 1.02% [P <.001]). Conclusions: Many patients with T2DM have very high HbA1c levels when initiating second-line therapy, indicating the need for earlier treatment intensification. Patient-specific factors merit consideration when making treatment decisions.
