ObjectiveTo systematically review the efficacy and safety of probiotics for the treatment of Helicobacter pylori (H.pylori) infection in children. MethodsWe electronically searched The Cochrane Library, PubMed, EMbase, CNKI, VIP and WanFang Data databases to collect randomized controlled trials (RCTs) about probiotics for the treatment of H.pylori infection in children from inception to January 2015. The references of included studies and conference proceedings were manually searched for additional studies. Two reviewers independently screened literature, extracted data and assessed the risk of bias of include studies. Then, meta-analysis was performed by using RevMan 5.3 software. ResultsA total of twelve RCTs were included, involving 1 227 patients. The result of meta-analysis showed that the probiotics adjuvant therapy group was superior to the control group in H.pylori eradication rates (OR=2.23, 95%CI 1.66 to 2.99, P<0.000 01) and the incidence of adverse effect (OR=0.31, 95%CI 0.18 to 0.53, P<0.000 1). ConclusionCurrent evidence shows that probiotics adjuvant therapy may be a new effective and safe solution in the treatment of H.pylori infections in children. Due to the limited quality and quantity of the included studies, more higher quality studies are needed to verify the above conclusion.
ObjectiveTo investigate the effect of PDCA cycle on the overall nursing care of patients in the hemodialysis center. MethodsTwenty hemodialysis patients between June and July 2014 were randomly selected as the intervention group, and another 20 hemodialysis patients between March and April 2014 were chosen as the control group. We compared the two groups of patients in terms of patients' satisfaction and the overall care quality of the nurses. ResultsOne month after the intervention, patients in the intervention group had a significantly higher satisfaction rate than the control group (P<0.05); Nurses in the intervention group achieved significantly higher scores in basic requirements, basic items and effect evaluation than those in the control group (P<0.05). ConclusionPDCA cycle can effectively improve the overall quality of nursing care in hemodialysis center and improve patients' satisfaction.
Objectives To assess the efficacy and safety of cytidine diphosphate choline for patients with acute stroke. Methods Such databases as PubMed, The Cochrane Library, EMbase, Web of Science, CNKI, VIP Database and Chinese Medical Association Journals were searched from the establishment to September of 2010, and the references of the included literatures were also searched to collect randomized controlled trials (RCTs) of cytidine diphosphate choline for patients with acute stroke. The data were extracted by two reviewers independently in accordance with the inclusion criteria. The quality of included trials was evaluated according to the Jadad scale standard. RevMan5.0 software was used for data analyses. Results Thirteen RCTs involving 2837 patients were included. The results of meta-analyses showed that, there was no significant difference in the mortality or the rate of dependency at the end of follow-up (OR=0.94, 95%CI 0.66 to 1.36, P=0.75) between the cytidine diphosphate choline group and the placebo group. But the total effective rate of the cytidine diphosphate choline group was higher than that of the placebo group with a significant difference (OR=1.72, 95%CI 1.41 to 2.10, Plt;0.000 01). Five trials reported the incidence of adverse reaction of cytidine diphosphate choline treatment which showed the adverse reaction was mild; no severe adverse events (SAEs) were reported and the clinical application was safe. Conclusion The cytidine diphosphate choline is effective and safe for acute stroke. However, it is invalid to reduce the mortality and the rate of dependency at the end of three months’ follow-up.
Objective To investigate the relative factors of sleep disorders in patients after arthroscopic knee surgery.MethodsThe clinical data of 155 patients undergoing arthroscopic knee surgery in West China Hospital of Sichuan University from October 1st 2017 to April 1st 2018 were analyzed. The sleep quality index was assessed by the Pittsburgh Sleep Quality Index. According to the scores, the patients were divided into two groups: the sleep disorder group and the non-sleep disorder group. Mindfulness level were evaluated by Mindful Attention Awareness Scale (MAAS). The binary logistic regression was used to assess the relationship between MAAS and sleep disorders.ResultsAmong the enrolled cases, there were 135 males and 20 females, with an average age of (34.12±12.13) years; 64 patients had poor sleep quality. The results of univariate analysis showed that the payment method, single or bilateral lesions, and MAAS score were the factors affecting sleep (P<0.05). The results of multivariate analysis indicated that with medical insurance [odds ratio (OR)=0.118, 95% confidence interval (CI) (0.021, 0.671), P=0.016], postoperative pain [OR=3.379, 95%CI (1.164, 9.812), P=0.025], bilateral lesions [OR=3.842, 95%CI (1.040, 14.191), P=0.044], and MAAS score ≥68 [OR=0.046, 95%CI (0.018, 0.121), P<0.001] were independent predictive factors for sleep disorders (P<0.05). Conclusion Postoperative pain reduction and mindfulness training may improve the patients’ sleep quality and reduce the incidence of sleep disorders.
Objective To assess the effectiveness of intensive versus routine education on diabetes mellitus for preventing diabetic foot ulcer. Methods We electronically searched CENTRAL (Issue 1, 2013), PubMed (1978-2013), EMbase (1978-2013), VIP (1989-2013) and WanFang Data (1980-2013), hand-searched correlated proceedings and retrieved the references of included studies, for the randomized controlled trials on intensive versus routine education on diabetes mellitus for preventing diabetic foot ulcer all over the world. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of included studies. Then, meta-analysis was performed using RevMan 5.2 software. Results Twelve trials involving 1 841 patients were finally included. The results of meta-analysis showed that: a) the incidence of diabetic foot ulcer in the intensive education group was lower than the routine group, with a significant difference (RR=0.51, 95%CI 0.30 to 0.84, P=0.008); b) two groups were alike in the amputation rate, with no significant difference (OR=0.54, 95%CI 0.17 to 1.67, P=0.28); and c) the score of knowledge on diabetes mellitus was higher in the intensive education group than in the routine education group, with a significant difference (MD=7.32, 95%CI 3.57 to 11.06, P=0.000 1). Conclusion Current evidence shows that: compared with routine education, intensive education could reduce the incidence of diabetic foot ulcer effectively. However, the above conclusion should be verified by conducting more high quality studies.
