Janusz Tarnowski Life and Works
No full textThe article is dedicated to the memory of the deceased priest Professor Janusz Tarnowski, who left behind an enormous huge scientific achievements. Janusz Tarnowski was primarily the author of a new trend of Christian personal and existential education, which the primary base is a dialogue and Christian education. In his pedagogical activity was a continuator of Janusz Korczak’s ideas enriched with the approach of dialogue and coexistence with God. He wrote about antipedagogical behavior and shown how to bring up correctly giving an example of his co-pupils cases. As a man who survived two wars, and served the ordained ministry in the Warsaw Uprising he paid a particular attention to education for peace, which according to him, starts from the family home. Janusz Tarnowski was in the first place a priest, tireless in spiritual leading. He supported also clergy and catechists by numerous studies and reflections connected with dilemmas of their professions
Systematic review and meta-analysis of randomized controlled trials assessing safety and efficacy of posterior pericardial drainage in patients undergoing heart surgery.
No full textOBJECTIVES
To investigate the potential beneficial effects of posterior pericardial drainage in patients undergoing heart surgery.
METHODS
Multiple online databases and relevant congress proceedings were screened for randomized controlled trials assessing the efficacy and safety of posterior pericardial drainage, defined as posterior pericardiotomy incision, chest tube to posterior pericardium, or both. Primary endpoint was in-hospital/30 days' cardiac tamponade. Secondary endpoints comprised death or cardiac arrest, early and late pericardial effusion, postoperative atrial fibrillation (POAF), acute kidney injury, pulmonary complications, and length of hospital stay.
RESULTS
Nineteen randomized controlled trials that enrolled 3425 patients were included. Posterior pericardial drainage was associated with a significant 90% reduction of the odds of cardiac tamponade compared with the control group: odds ratio (95% confidence interval) 0.13 (0.07-0.25); P < .001. The corresponding event rates were 0.42% versus 4.95%. The odds of early and late pericardial effusion were reduced significantly in the intervention arm: 0.20 (0.11-0.36); P < .001 and 0.05 (0.02-0.10); P < .001, respectively. Posterior pericardial drainage significantly reduced the odds of POAF by 58% (P < .001) and was associated with significantly shortened (by nearly 1 day) overall length of hospital stay (P < .001). Reductions in postoperative complications translated into significantly reduced odds of death or cardiac arrest (P = .03) and numerically lower odds of acute kidney injury (P = .08).
CONCLUSIONS
Posterior pericardial drainage is safe and simple technique that significantly reduces not only the prevalence of early pericardial effusion and POAF but also late pericardial effusion and cardiac tamponade. These benefits, in turn, translate into improved survival after heart surgery

Velocity and Concentration field of discharge from a boat propeller
No full textTwo-stroke outboard boat engines using total loss lubrication deposit a significant proportion of their lubricant and fuel directly into the water. The purpose of this work is to document the velocity and concentration field characteristics of a submerged swirling water jet emanating from a propeller in order to provide information on its fundamental characteristics. Measurements of the velocity and concentration field were performed in a turbulent jet generated by a model boat propeller (0.02 m diameter) operating at 1500 rpm and 3000 rpm. The measurements were carried out in the Zone of Established Flow up to 50 propeller diameters downstream of the propeller. Both the mean axial velocity profile and the mean concentration profile showed self-similarity. Further, the stand deviation growth curve was linear. The effects of propeller speed and dye release location were also investigated
Meta-analysis of uninterrupted as compared to interrupted oral anticoagulation with or without bridging in patients undergoing coronary angiography with or without percutaneous coronary intervention.
No full textOBJECTIVES
To assess safety and effectiveness of different periprocedural antithrombotic strategies in patients receiving long-term oral anticoagulation and undergoing coronary angiography with or without percutaneous coronary intervention (PCI).
METHODS
Studies comparing uninterrupted oral anticoagulation (UAC) with vit. K antagonists vs interrupted oral anticoagulation (IAC) with or without bridging anticoagulation before coronary procedures were eligible for inclusion in the current meta-analysis. Endpoints selected were 30-day composite of major adverse cardiovascular or cerebrovascular and thromboembolic events (MACCE) and major bleeding.
RESULTS
Eight studies (7 observational and 1 randomized controlled trial [N=2325pts.]) were included in the analysis. There was no difference in MACCE between UAC and IAC; RR (95%CIs): 0.74 (0.34-1.64); p=0.46 but there was a statistically significant MACCE risk reduction with UAC as compared to IAC with bridging: 0.52 (0.29-0.95); p=0.03. Likewise, there were no statistically significant differences between UAC vs IAC in regard to major bleeding: 0.62 (0.16-2.43); p=0.49; but as compared to IAC with bridging, UAC was associated with statistically significant 65% lower risk of major bleeding: 0.35 (0.13-0.92); p=0.03. Additionally, meta-regression analysis revealed significant linear correlation between log RR of MACCE (β=-4.617; p<0.001) and major bleeding (β=6.665; p=0.022) and mean value of target INR suggestive of higher thrombotic and secondary haemorrhagic risk below estimated INR cut-off of 2.17-2.27 within 30days.
CONCLUSIONS
Uninterrupted OAC is at least as safe as interrupted OAC, and seems to be much safer than interrupted OAC with bridging anticoagulation in patients undergoing coronary angiography with or without PCI

W podrozdziale trzecim Lubelski omawia dokumenty poświęcone Korczakowi, a w czwartym - filmowe adaptacje jego książek, na czele z "Królem Maciusiem I" (1958) Wandy Jakubowskiej.The author discusses the title theme in all aspects.
