ABSTRACT
Background: A large number of studies have been conducted to determine whether there is an association between preadmission statin use and improvement in outcomes following critical illness, but the conclusions are quite inconsistent. Therefore, this meta-analysis aims to include the present relevant PSM researches to examine the association of preadmission use of statins with the mortality of critically ill patients. Methods: The PubMed, Web of Science, Embase electronic databases, and printed resources were searched for English articles published before March 6, 2020 on the association between preadmission statin use and mortality in critically ill patients. The included articles were analyzed in RevMan 5.3. The Newcastle-Ottawa Scale (NOS) was used to conduct quality evaluation, and random/fixed effects modeling was used to calculate the pooled ORs and 95% CIs. We also conducted subgroup analysis by outcome indicators (30-, 90-day, hospital mortality). Results: All six PSM observational studies were assessed as having a low risk of bias according to the NOS. For primary outcome-overall mortality, the pooled OR (preadmission statins use vs. no use) across the six included studies was 0.86 (95% CI, 0.76-0.97; P = 0.02). For secondary outcome-use of mechanical ventilation, the pooled OR was 0.94 (95% CI, 0.91-0.97; P = 0.0005). The corresponding pooled ORs were 0.67 (95% CI, 0.43-1.05; P = 0.08), 0.91 (95% CI, 0.83-1.01; P = 0.07), and 0.86 (95% CI, 0.83-0.89; P < 0.00001) for 30-, 90-day, and hospital mortality, respectively. Conclusions: Preadmission statin use is associated with beneficial outcomes in critical ill patients, indicating a lower short-term mortality, less use of mechanical ventilation, and an improvement in hospital survival. Further high-quality original studies or more scientific methods are needed to draw a definitive conclusion.
ABSTRACT
BACKGROUND: The incidence of hepatocellular carcinoma (HCC) in non-alcoholic fatty liver disease (NAFLD) is increasing worldwide. Higher perioperative risks may be anticipated due to underlying steatohepatitis, while long-term outcomes after liver resection are unknown. We sought to investigate outcomes after liver resection for NAFLD-HCC versus hepatitis B virus (HBV)-HCC using propensity score matching (PSM). METHODS: Consecutive patients who underwent liver resection for HCC between 2003 and 2014 were identified from a multicenter database. Patients with NAFLD-HCC were matched one-to-one to patients with HBV-HCC. RESULTS: Among 1483 patients identified, 96 (6.5%) had NAFLD-HCC and 1387 (93.5%) had HBV-HCC. Patients with NAFLD-HCC were older (median age 57 vs. 50 years), more often overweight (50.0% vs. 37.5%), less often to have cirrhosis (30.2% vs. 72.5%) and liver dysfunction (Child-Pugh B: 4.2% vs. 10.7%), had larger tumor size (median 7.2 vs. 6.2 cm) yet had better tumor differentiation (27.1% vs. 17.6%) compared with patients with HBV-HCC (all P < 0.05). Perioperative mortality and morbidity were comparable between the two groups (1.0% vs. 1.4% and 20.8% vs. 23.2%, both P > 0.05). No differences were noted in median OS and RFS among patient with NAFLD-HCC versus HBV-HCC before or after PSM. CONCLUSION: While patients with NAFLD-HCC had different clinical characteristics than patients with HBV-HCC, liver resection resulted in similar perioperative outcomes and comparable OS and RFS among patients with NAFLD-HCC and HBV-HCC.
