Optimal Antiplatelet Therapy Following Left Atrial Appendage Closure in Dialyzed Patients

Background: Transcatheter left atrial appendage closure (LAAC) has been shown to be non-inferior to oral anticoagulation in preventing cardioembolic strokes associated with atrial fibrillation. However, an optimal antithrombotic treatment regimen following successful LAAC remains an unresolved issue and may significantly contribute to long-term safety and efficacy. Nowadays LAAC is mainly performed in patients with contraindications for oral anticoagulation due to high bleeding risk. Dialyzed patients with end-stage renal disease and atrial fibrillation have simultaneously high thromboembolic and bleeding risk. Such patients were excluded from randomized trials and data on the LAAC efficacy in this population is limited thus prospective studies are warranted. Objective: SAFE-LAAC CKD Trial has been designed as a comparative health effectiveness study with the following aims: 1. compare the safety and efficacy of 30 days vs. 6 months of dual antiplatelet therapy following LAAC with Amplatzer or WATCHMAN device (randomized comparison) 2. compare the safety and efficacy of stopping all antithrombotic and antiplatelet agents 6 months after LAAC vs. long-term treatment with a single antiplatelet agent (nonrandomized comparison) Patient population: Patients (n=80) with the end-stage renal disease treated with chronic haemodialysis or peritoneal dialysis, after successful LAAC with Amplatzer or WATCHMAN device Perspective: Results of this pilot trial will provide: 1. data to aid practitioners and guideline writers recommend the most optimal antithrombotic treatment after LAAC, 2. data on the safety and efficacy of LAAC in dialyzed patients, and 3. data to support power calculations for designing future randomized trials. Methodology: SAFE LAAC CKD has been designed as a multicenter (planned contribution of 7 centers in Poland), open-label, comparative health effectiveness trial with central, independent adjudication of events comprising the primary end-point. The first part of the trial is randomized and after 6 months of follow-up continues for another 12 months as a non-randomized study. Timeline: The duration of the trial has been planned for 5 years. The enrollment phase has been planned for 3 years.

Effects of Switching From Cigarettes to Tobacco Heating System on Coronary Atherosclerosis Progression

Objective: To evaluate the impact of heated versus combustion tobacco products on progression of atherosclerosis in patients with CAD unable(unwilling) to quit smoking. Background Despite the efforts to curb smoking and full awareness of its deleterious health impact, smoking remains a significant contributor to morbidity and mortality. Some health impact of smoking may be improved by other forms of cigarettes than traditional combustion, especially for subjects unwilling or unable to stop smoking. As recently as 2020, one of heated tobacco products (HTP)(IQOS) was FDA Authorized as a 'Reduced Exposure' product. The available evidence to date allows to conclude that the IQOS system heats tobacco but does not burn it, which significantly reduces the production of harmful and potentially harmful chemicals. Scientific studies have shown that switching completely from conventional cigarettes to the IQOS system significantly reduced body's exposure to harmful or potentially harmful chemicals. There is also evidence indicating lower levels of inflammatory markers and improved vascular function associated with use of heated tobacco products. However, it is unknown whether the reduction in the exposure translates into potential reduction of harm within cardiovascular system, as compared to the traditional (combustion) cigarettes. The evidence is of crucial importance for patients with cardiovascular diseases, medical community, and national health authorities planning evidence based policies regarding HTP/cigarettes. Methods: Prospective, single-centre, open-label, randomised study including 180 stable patients with coronary artery disease (CAD) as diagnosed on CCTA, without indications for invasive treatment, unable(unwilling) to quit smoking, randomised 1:1 to either heated (group H) or combustion (group C) tobacco products and followed for 18 months. The follow-up is accomplished with CCTA scan. The study clinical visits are planned at 1, 3, 6, 12, and 18 months. The primary outcome is change in non calcified plaque volume at 18 months between H and C groups (intention to treat design).

SA Versus SOI Surfaces for Single Implant-supported Crown

This study aimed to evaluate if there are some benefits using novel implant surface. This surface should improve the secondary implant stability, reducing the overall time needed for the osseointegration. main benefits in clinical practice should be reduced treatment time.

A Study of CPI-0209 in Patients With Advanced Solid Tumors and Lymphomas

Emerging evidence suggests that EZH2 is overexpressed in many cancer types and has a pivotal role in disease progression. This is a Phase 1/2, open-label, multi-center, FIH study designed to evaluate the safety and tolerability and preliminary clinical activity of CPI-0209, an EZH2/1 inhibitor as monotherapy in patients with advanced solid tumors and lymphomas. Phase 1 is composed of a CPI-0209 Dose Escalation period in patients with advanced tumors and aims to determine maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) of CPI-0209 as monotherapy in patients with advanced tumors. Phase 2 is planned to evaluate safety and tolerability and antitumor activity of CPI-0209 in six disease-specific cohorts (M1 to M6). Patients in Cohorts M1, M2, M3, M5, and M6 will be enrolled at 10 to 29 patients per cohort, using a Simon 2-stage design. Cohort M4 will enroll up to 20 patients with lymphoma in a single-stage. The primary aim of Phase 2 part of the study is to evaluate the antitumor activity of CPI-0209, and characterize the safety and tolerability of CPI-0209 as monotherapy in patients with selected tumors. In Phase 2, two additional doses are planned to be evaluated in cohorts M2 and M3 in 2 stages: Stage 2a and Stage 2b. In Stage 2a approximately 20 patients will be enrolled per cohort and will be randomized 1:1 to receive 2 prespecified dose levels of CPI-0209 once daily. When protocol criteria for initiating Stage 2b will be fulfilled after completion of Stage 2a, then Stage 2b will be opened for enrolment of additional 10 patients in one or both dose arms in each of the two cohorts. Thus, up to 40 patients per cohort (M2 and M3) could be enrolled.

Pulmonary Embolism WArsaw REgistry

The Pulmonary Embolism WArsaw REgistry (PE-aWARE) is an on-going prospective observational study of patients with confirmed acute pulmonary embolism (APE). Carried out since January 2008, the registry includes consecutive patients hospitalized at a single centre. The primary data recorded include details of each patient's clinical status, co-morbidities, the prescribed treatment, the results of additional studies (ie EKG, imaging studies), and the outcome. The study endpoints comprise clinically recognized (and objectively confirmed) recurrences of PE, major and minor bleeding complications classified according to the International Society on Thrombosis and Haemostasis classification, need for cardiopulmonary resuscitation or catecholamines, and death. Collecting the fore mentioned data allows for clinicians to better manage the diagnostic workup and treatment and thus facilitates the prevention of possible future complications in APE patients.
