Methods： Systematic searches on PubMed, EM- BASE, Cochrane Library, Web of Science, CBM, CNKI, Wanfang and VIP were performed for randomized controlled trials （RCTs） or quasi-RCTs which explored the effects of heated gel mattress on prevention of hypothermia in premature infants relative to conventional alternatives. Studies were screened according to inclusion and exclusion criteria, extracted data and assessed quality. Then, meta-analysis and trial sequential analysis were performed by RevMan 5.3 and TSA vO.9 software developed at the Copenhagen Clinical Trials Center in Denmark, independently. Results： This systematic review included 10 studies which comprised 7 RCTs and 3 quasi-RCTs, encompassing 773 patients. The results of meta-analysis showed that in heated gel mattress group admission temperature on neonatal intensive care unit （SMD, 0.63; 95% CI, 0.40 to 0.87; P = 0.00）, incidence of hypothermia （RR, 0.73; 95% CI, 0.57 to 0.93; P = 0.01） and hyperthermia （RR, 1.82; 95% CI, 1.31 to 2.541 P = 0.00） compared with the control group had significantly statistical difference; however, there was no significant difference in admission temperature on exothermic mattresses or TransWarmer mattress group, mortality, sepsis, retinopathy of prematurity, intraventricular hemorrhage Ⅲ/Ⅳ between two groups, trial sequential analysis confirmed that the pooled results of admission temperature on neonatal intensive care unit and hyperthermia were stable and reliable; but the combination of low-temperature incidence and mortality indicators suggested that the sample size was insufficient. Conclusion： Heated gel mattress is a safe and effective re- warming intervention that can improve body temperature of hypothermic preterm infants during transport, reduce the incidence of hypothermia and does not increase the incidence of morbidity and complications. However, it is recommended that clinical monitoring of body temperature should be performed dynamically to decrease the potential risk of high fever. In addition, due to the limitation of quantity and quality of included studies, its cost-effectiveness and far-reaching influence on long-term follow-up outcomes need further evaluation through clinical multicenter, large sample, and high-quality research.展开更多

Several studies have demonstrated independent predictors of mortality. The aim of this work is indeed to identify these predictors. Patients and Methods: We conducted a retrospective study of 1080 cirrhotic patients hospitalized in our department of gastroenterology and hepatology between January 2001 and August 2010. A descriptive study of the study population was performed, and a univariate analysis looking for an association between intra-hospital mortality, and clinical, biological, etiological and sociodemographic characteristics of our patients. Results: The average age of our patients was 54 years, with an equal number of men and women. 41.1% of patients had cirrhosis secondary to hepatitis C and 18.5% had cirrhosis secondary to hepatitis B. 26.1% of our patients were CHILD C. Intra-hospital mortality was 8.7% (97 deaths) with a mean of 23.4 ± 35.8 months. Univariate analysis showed that the intra-hospital mortality was significantly associated with higher age (p = 0.049) as well as the reasons for admissions like hepatic encephalopathy, and hematemesis (p < 0.0001), melena, jaundice and ascites (p = 0.001). Among the biological parameters analyzed in univariate analysis, significant associations with mortality were objectified for high white blood cell count (p = 0.035), and high serum bilirubin and creatinine (p < 0.0001);low rate of prothrombin time (PT) (p < 0.0001), of albumin (p = 0.0001) and of serum sodium (p < 0.0001). Among the complications analyzed, significant associations with mortality were objectified for jaundice, ascites (p = 0.001), hemorrhagic decompensation, hepatic encephalopathy, and spontaneous bacterial peritonitis (p < 0.001). Univariate analysis of the etiology of cirrhosis objectified significant associations for cirrhosis secondary to hepatitis B (p = 0.001) and hepatitis C (p = 0.022). Multivariate analysis objectified four independent predictors of mortality: hepatic encephalopathy, infection (hyper leukocytosis ≥ 10,000/mm3), renal failure (serum creatinine ≥ 15 mg/l) and hyponatremia. Conclusion: In our series, we identified four independent predictors of intra-hospital mortality in cirrhotic patients: hepatic encephalopathy, infection, renal failure and hyponatremia.展开更多
