Introduction: Left atrial appendage closure (LAAC) with LARIAT offers an alternative to oral anticoagulation (OAC) for patients with atrial fibrillation. The aim of this study was to present long-term clinical outcomes of LAAC in these patients (AF).
Material And Methods: A prospective, single-center study was performed in 139 patients undergoing LAAC with Lariat. Thromboembolic events, severe bleeding and mortality rate were recorded. The reduction in risk of thromboembolism and bleeding after LAAC was calculated.
Results: The mean CHADS2-score was 1.8 ± 1.0, mean CHA2DS2-VASc score was 2.9 ± 1.6 and HAS-BLED score was 3.1 ± 1.1. After 428.4 patient-years of follow-up (mean 4.2±1.0 years), the thromboembolism rate was 0.6% with a calculated thromboembolism risk reduction of 81%. The severe bleeding rate was 0.8%; calculated bleeding risk reduction was 78%. The overall mortality rate was 1.6%.
Conclusions: Long-term outcomes show that LAAC with Lariat is a safe and effective treatment for stroke prevention and bleeding risk reduction in AF patients with a high level of underlying risk.

Objective: To study the use of a dementia screening tool in our clinic cohort of adults with Down syndrome.
Study Design: A retrospective chart review of patients with Down syndrome was conducted to follow the use of the Adaptive Behaviour Dementia Questionnaire (ABDQ) in a dementia screening protocol. The ABDQ results for patients aged 40 years and older at a Down syndrome specialty clinic program were assessed.
Short (2-Hour) Non-Oxygenated End-Ischemic Hypothermic Perfusion Versus Cold Storage in the Setting of Renal Transplantation.

Background: Kidney transplantation (KT) is the most effective treatment for end-stage renal disease. End-ischemic hypothermic machine perfusion (EI-HMP) has emerged as a promising method for preserving grafts before transplantation. This study aimed to compare graft function recovery in KT recipients of deceased brain-death (DBD) grafts preserved with EI-HMP versus static cold storage (SCS).

Bone mineral density (BMD) levels achieved on osteoporosis treatment are predictive of subsequent fracture risk, and T-score > -2.5 has been proposed as a minimum treatment target for women with osteoporosis. Knowing the likelihood of attaining target T-scores with different medications for different baseline BMD levels can help determine appropriate initial treatment for individual patients.

In the 1980s, Poland was a medium-endemic country, with one of the highest incidences of hepatitis B in Europe (45/10 inhabitants). Pursuant to the WHO guidelines, obligatory vaccination was introduced in 1994-1996 (as a part of hepatitis B prophylaxis for newborns), and in 2000-2011, all 14-year-olds were vaccinated. To prevent transfusion-transmitted HBV infection (TT-HBV), since the 1970s, each donation has been tested for HBsAg and, since 2005, additionally for the presence of HBV DNA.
