Background: Non-alcoholic fatty liver disease (NAFLD) and its advanced form non-alcoholic steatohepatitis (NASH) are the most common causes of elevated liver enzymes in the general population. NASH, and to a lesser extent NAFLD have been associated with increased liver-related, cardiovascular disease (CVD), and allcause mortality. No effective treatment is widely acceptable. Objective: The purpose of this review is to summarize available data on the impact of statins on NAFLD and NASH. Method: A comprehensive review of the literature was performed to identify studies assessing the effect of statin use in NAFLD/NASH. Results: Recent reports have shown that the use of statins in patients with elevated plasma aminotransferases may be beneficial. Post hoc data from three large prospective randomized clinical trials (n>11, 000) suggest that specific statins (mainly atorvastatin) ameliorate NAFLD/NASH and reduce CVD events twice as much as in those with normal liver function. Several biopsy studies have found that rosuvastatin use is related with significant histological ameliorating effects in the setting of NASH. Statin treatment may also protect from hepatocellular carcinoma (HCC) related to NAFLD/NASH. Conclusion: Since NAFLD/NASH patients have high CVD risk, they will probably require a statin. Thus, why not select a specific statins (atorvastatin or rosuvastatin, both generic now) that offer a substantial liver- and CVDrelated adverse event reduction? The administration of statins in these patients is as safe as in the general population.

The use of opioid analgesics to control pain after median sternotomy in cardiac surgical patients is worldwide accepted and established. However, opioids have a wide range of possible side effects, concerning prolonged extubation time, gastrointestinal tract dyskinesia and urinary tract disorders mostly retention. All these may lead to a prolonged ICU stay or overall hospitalization time increase.Objective: To determine whether a continuous subcutaneous regional anesthetic infusion delivered directly to the sternotomy site would result in decreased levels of postoperative pain and opioid requirements in cardiac surgical patients undergoing median sternotomy. Method:The continuous subcutaneous infusion (OnQ Painbuster system) was applied in 37 patients. 3 patients were exempted due to prolonged ICU stay. 29 patients underwent CABG, 5 had AVR, 1 MVR and modified Maze, 1 patient had a 3-valve repair due to endocarditis and another one had reconstruction of the left ventricle. Requirements of opioid analgesics were recorded for 96 hours after operation. Pain was assessed using the visual analog scale and the total postoperative hospital length of stay was also measured. Results:The postoperative pain was significantly diminished (0 -3 at VAS). The mean postoperative length of stay was 5,8 days, rather improved compared to the average stay of 6,7 days. Conclusion:Continuous subcutaneous infusion of ropivacaine directly at the median sternotomy significantly diminishes postoperative pain and the need for opioid analgesic use. Moreover, it seems to reduce overall postoperative length of stay for all cardiac surgical patients.

Purpose The incidence, patient features, risk factors and outcomes of surgery-associated postoperative acute kidney injury (PO-AKI) across different countries and health care systems is unclear. Methods We conducted an international prospective, observational, multi-center study in 30 countries in patients undergoing major surgery (> 2-h duration and postoperative intensive care unit (ICU) or high dependency unit admission). The primary endpoint was the occurrence of PO-AKI within 72 h of surgery defined by the Kidney Disease: Improving Global Outcomes (KDIGO) criteria. Secondary endpoints included PO-AKI severity and duration, use of renal replacement therapy (RRT), mortality, and ICU and hospital length of stay. Results We studied 10,568 patients and 1945 (18.4%) developed PO-AKI (1236 (63.5%) KDIGO stage 1500 (25.7%) KDIGO stage 2209 (10.7%) KDIGO stage 3). In 33.8% PO-AKI was persistent, and 170/1945 (8.7%) of patients with PO-AKI received RRT in the ICU. Patients with PO-AKI had greater ICU (6.3% vs. 0.7%) and hospital (8.6% vs. 1.4%) mortality, and longer ICU (median 2 (Q1-Q3, 1–3) days vs. 3 (Q1-Q3, 1–6) days) and hospital length of stay (median 14 (Q1-Q3, 9–24) days vs. 10 (Q1-Q3, 7–17) days). Risk factors for PO-AKI included older age, comorbidities (hypertension, diabetes, chronic kidney disease), type, duration and urgency of surgery as well as intraoperative vasopressors, and aminoglycosides administration. Conclusion In a comprehensive multinational study, approximately one in five patients develop PO-AKI after major surgery. Increasing severity of PO-AKI is associated with a progressive increase in adverse outcomes. Our findings indicate that PO-AKI represents a significant burden for health care worldwide.
