AIM To explore the outcomes and the appropriate treatment for patients with moderately severe acute pancreatitis(AP).METHODS Statistical analysis was performed on data from the prospectively collected database of 103 AP patients admitted to the Department of Surgery,Hospital of Lithuanian University of Health Sciences in 2008-2013. All patients were confirmed to have the diagnosis of AP during the first 24 h following admission. The severity of pancreatitis was assessed by MODS and APACHE Ⅱ scale. Clinical course was re-evaluated after 24,48 and 72 h. All patients were categorized into 3 groups based on Atlanta 2012 classification: Mild,moderately severe,and *** and management in moderately severe group were also compared to mild and severe cases according to Atlanta 1992 and 2012 *** Fifty-three-point four percent of patients had edematous while 46.6 % were diagnosed with necrotic AP. The most common cause of AP was alcohol(42.7%) followed by alimentary(26.2%),biliary(26.2%) and idiopathic(4.9%). Under Atlanta 1992 classification 56(54.4%) cases were classified as "mild" and 47(45.6%) as "severe". Using the revised classification(Atlanta 2012),the patient stratification was different: 49(47.6%) mild,27(26.2%) moderately severe and 27(26.2%) severe AP cases. The two severe groups(Atlanta 1992 and Revised Atlanta 2012) did not show statistically significant differences in clinical parameters,including ICU stay,need for interventional treatment,infected pancreatic necrosis or mortality rates. The moderately severe group of 27 patients(according to Atlanta 2012) had significantly better outcomes when compared to those 47 patients classified as severe form of AP(according to Atlanta 1992) with lower incidence of necrosis and sepsis,lower APACHE Ⅱ(P = 0.002) and MODS(P = 0.001) scores,shorter ICU stay,decreased need for interventional and surgical *** Study shows that Atlanta 2012 criteria are more accurate,reduce unnecessa

In the current study, research on the performance characteristics of an adsorption cooling system supplied by solar energy is presented. The main task for the analyzed system was to ensure cooling load for the non-residential building in cold climate country. A 8.0 k W adsorption thermal cooling system was studied. The system got heat produced by evacuated tube solar collectors. The parametric simulation study was carried using a TRNSYS(Transient Systems Simulation) program to determine the influence of various parameters on the system performance. The dependencies of collector slope and the total absorber area on solar fraction, discarded energy, coefficient of performance, seasonal performance factor were studied. The highest solar fraction, coefficient of performance and seasonal performance factor values were obtained if the collector slope was approximately 30 degrees and the absorber area was 16 m for the analyzed cases. The total primary energy consumption of the system was examined for various cases of primary energy factor for auxiliary heat and consumed electricity. On the basis of the results, it was proposed the expression of total primary energy consumption. The obtained results could be used for the recommendation preparations for decision makers to select a small scale solar cooling adsorption system.
