BACKGROUND/AIMS: We assessed the usefulness of oral glutamine challenge (OGC) and minimal hepatic encephalopathy in evaluating risk of overt hepatic encephalopathy in cirrhotic patients.METHODS: Minimal hepatic encephalopathy (MHE) was inferred using neuro-psychological tests. Venous ammonia concentrations were measured pre- and post-60 min (NH(3)-60m) of a 10 g oral glutamine load. Receiver-operating-characteristic curve analysis indicated a pathological glutamine tolerance cut-off value of NH(3)-60m >128 microg/dl. RESULTS: In healthy control subjects (n=10) ammonia concentrations remained unchanged but increased significantly in cirrhotic patients (from 70.41+/-45.2 to 127.43+/-78.6; P<0.001). In multiple logistic regression analysis, altered OGC was related to Child-Pugh (odds ratio, OR=7.69; 95% confidence interval, CI=1.72-33.3; P<0.01) and MHE (OR=5.45; 95% CI=1.17-25.4; P<0.05). In the follow-up 11 patients (15%) developed overt hepatic encephalopathy (HE). In multivariate analysis OGC (OR=14.5; 95% CI=1.26-126.3) and MHE (OR=1.56; 95% CI=1.02-21.9) were independently related with HE in the follow-up. Patients with MHE and altered OGC showed significantly higher risk of overt HE in the follow-up (60%) than patients without MHE and normal OGC (2.8%) (Log rank test=21.60; P<0.0001). CONCLUSIONS: A pathological OGC in patients with MHE appears to be a prognostic factor for the development of overt hepatic encephalopathy, whereas a normal OGC in patients without MHE could exclude risk of overt HE. 相似文献

AIM: To investigate the differences in outcome following pylorus preserving pancreaticoduodenectomy (PPPD) and subtotal stomach-preserving pancreaticoduodenectomy (SSPPD).METHODS: Major databases including PubMed (Medline), EMBASE and Science Citation Index Expanded and the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library were searched for comparative studies between patients with PPPD and SSPPD published between January 1978 and July 2014. Studies were selected based on specific inclusion and exclusion criteria. The primary outcome was delayed gastric emptying (DGE). Secondary outcomes included operation time, intraoperative blood loss, pancreatic fistula, postoperative hemorrhage, intraabdominal abscess, wound infection, time to starting liquid diet, time to starting solid diet, period of nasogastric intubation, reinsertion of nasogastric tube, mortality and hospital stay. The pooled odds ratios (OR) or weighted mean difference (WMD) with 95% confidence intervals (95%CI) were calculated using either a fixed-effects or random-effects model.RESULTS: Eight comparative studies recruiting 650 patients were analyzed, which include two RCTs, one non-randomized prospective and 5 retrospective trial designs. Patients undergoing SSPPD experienced significantly lower rates of DGE (OR = 2.75; 95%CI: 1.75-4.30, P < 0.00001) and a shorter period of nasogastric intubation (OR = 2.68; 95%CI: 0.77-4.58, P < 0.00001), with a tendency towards shorter time to liquid (WMD = 2.97, 95%CI: -0.46-7.83; P = 0.09) and solid diets (WMD = 3.69, 95%CI: -0.46-7.83; P = 0.08) as well as shorter inpatient stay (WMD = 3.92, 95%CI: -0.37-8.22; P = 0.07), although these latter three did not reach statistical significance. PPPD, however, was associated with less intraoperative blood loss than SSPPD [WMD = -217.70, 95%CI: -429.77-(-5.63); P = 0.04]. There were no differences in other parameters between the two approaches, including operative time (WMD = -5.30, 95%CI: -43.44-32.84; P = 0.79), pancreatic fistula (OR = 0.91; 95%CI: 0.56-1.49; P = 0.70), postoperative hemorrhage (OR = 0.51; 95%CI: 0.15-1.74; P = 0.29), intraabdominal abscess (OR = 1.05; 95%CI: 0.54-2.05; P = 0.89), wound infection (OR = 0.88; 95%CI: 0.39-1.97; P = 0.75), reinsertion of nasogastric tube (OR = 1.90; 95%CI: 0.91-3.97; P = 0.09) and mortality (OR = 0.31; 95%CI: 0.05-2.01; P = 0.22).CONCLUSION: SSPPD may improve intraoperative and short-term postoperative outcomes compared to PPPD, especially DGE. However, these findings need to be further ascertained by well-designed randomized controlled trials. 相似文献

Several randomized controlled trials (RCT) have shown that water infusion in lieu of air insufflation reduces sedation rate and pain score and increases cecal intubation rate in colonoscopy. The aim of the present study was to confirm the beneficial effects of the water intubation method over the air method. Electronic databases were searched to identify RCT reporting colonoscopy detection using the water method. The pooled data of sedation rate, pain score and other procedure‐related outcomes were analyzed. Then, 15 full‐text articles were selected and assessed. Nine trials with high‐quality scores were enrolled into this meta‐analysis including a total of 1414 participants. Pooled odds ratio (OR) of sedation rate was 0.392 (95% confidence interval (CI): 0.288–0.533, P = 0.000). Pooled weighted mean difference (WMD) of pain score was ?1.543 (95% CI: ?2.107–?1.069,P = 0.000). Pooled OR of cecal intubation rate was 1.90 (95% CI: 1.29–2.82, P = 0.001). Pooled OR of polyp detection rate and adenoma detection rate were 0.805 (95% CI: 0.606–1.069, P = 0.134) and 0.913 (95% CI: 0.681–1.223, P = 0.168), respectively. Pooled WMD of cecal intubation time was 0.701 (95% CI: ?0.486–1.889, P = 0.247). This meta‐analysis confirmed that the water method significantly reduced sedation rate and degree of pain without decreasing cecal intubation rate and disease detection rate and without requiring more cecal intubation time, suggesting that the novel water method is better than the conventional air method in colonoscopy detection. 相似文献

AIM: To investigate endoscopic and clinicopathologic characteristics of early gastric cancer (EGC) according to microsatellite instability phenotype.METHODS: Data were retrospectively collected from a single tertiary referral center. Of 981 EGC patients surgically treated between December 2003 and October 2007, 73 consecutive EGC patients with two or more microsatellite instability (MSI) mutation [high MSI (MSI-H)] and 146 consecutive EGC patients with one or no MSI mutation (non-MSI-H) were selected. The endoscopic and clinicopathologic features were compared between the MSI-H and non-MSI-H EGC groups.RESULTS: In terms of endoscopic characteristics, MSI-H EGCs more frequently presented with elevated pattern (OR 4.38, 95% CI: 2.40-8.01, P < 0.001), moderate-to-severe atrophy in the surrounding mucosa (OR 1.91, 95% CI: 1.05-3.47, P = 0.033), antral location (OR 3.99, 95% CI: 2.12-7.52, P < 0.001) and synchronous lesions, compared to non-MSI-H EGCs (OR 2.65, 95% CI: 1.16-6.07, P = 0.021). Other significant clinicopathologic characteristics of MSI-H EGC included predominance of female sex (OR 2.77, 95% CI: 1.53-4.99, P < 0.001), older age (> 70 years) (OR 3.30, 95% CI: 1.57-6.92, P = 0.002), better histologic differentiation (OR 2.35, 95% CI: 1.27-4.34, P = 0.007), intestinal type by Lauren classification (OR 2.34, 95% CI: 1.15-4.76, P = 0.019), absence of a signet ring cell component (OR 2.44, 95% CI: 1.02-5.86, P = 0.046), presence of mucinous component (OR 5.06, 95% CI: 1.27-20.17, P = 0.022), moderate-to-severe lymphoid stromal reaction (OR 3.95, 95% CI: 1.59-9.80, P = 0.003), and co-existing underlying adenoma (OR 2.66, 95% CI: 1.43-4.95, P = 0.002).CONCLUSION: MSI-H EGC is associated with unique endoscopic and clinicopathologic characteristics including frequent presentation in protruded type, co-existing underlying adenoma, and synchronous lesions. 相似文献

AIM:To conduct a meta-analysis comparing laparoscopic total gastrectomy(LTG)with open total gastrectomy(OTG)for the treatment of gastric cancer.METHODS:Major databases such as Medline(PubMed),Embase,Academic Search Premier(EBSCO),Science Citation Index Expanded and the Cochrane Central Register of Controlled Trials(CENTRAL)in The Cochrane Library were searched for studies comparing LTG and OTG from January 1994 to May 2013.Evaluated endpoints were operative,postoperative and oncological outcomes.Operative outcomes included operative time and intraoperative blood loss.Postoperative recovery included time to first fatus,time to first oral intake,hospital stay and analgesics use.Postoperative complications comprised morbidity,anastomotic leakage,anastomotic stenosis,ileus,bleeding,abdominal abscess,wound problems and mortality.Oncological outcomes included positive resection margins,number of retrieved lymph nodes,and proximal and distal resection margins.The pooled effect was calculated using either a fixed effects or a random effects model.RESULTS:Fifteen non-randomized comparative studies with 2022 patients were included(LTG-811,OTG-1211).Both groups had similar short-term oncological outcomes,analgesic use(WMD-0.09;95%CI:-2.39-2.20;P=0.94)and mortality(OR=0.74;95%CI:0.24-2.31;P=0.61).However,LTG was associated with a lower intraoperative blood loss(WMD-201.19 mL;95%CI:-296.50--105.87 mL;P<0.0001)and overall complication rate(OR=0.73;95%CI:0.57-0.92;P=0.009);fewer wound-related complications(OR=0.39;95%CI:0.21-0.72;P=0.002);a quicker recovery of gastrointestinal motility with shorter time to frst fatus(WMD-0.82;95%CI:-1.18--0.45;P<0.0001)and oral intake(WMD-1.30;95%CI:-1.84--0.75;P<0.00001);and a shorter hospital stay(WMD-3.55;95%CI:-5.13--1.96;P<0.0001),albeit with a longer operation time(WMD 48.25 min;95%CI:31.15-65.35;P<0.00001),as compared with OTG.CONCLUSION:LTG is safe and effective,and may offer some advantages over OTG in the treatment of gastric cancer. 相似文献

AIM: To compare the therapeutic effects of proton pump inhibitors vs H2 receptor antagonists for upper gastrointestinal bleeding in patients after successful endoscopy.METHODS: We searched the Cochrane library, MEDLINE, EMBASE and PubMed for randomized controlled trials until July 2014 for this study. The risk of bias was evaluated by the Cochrane Collaboration’s tool and all of the studies had acceptable quality. The main outcomes included mortality, re-bleeding, received surgery rate, blood transfusion units and hospital stay time. These outcomes were estimated using odds ratios (OR) and mean difference with 95% confidence interval (CI). RevMan 5.3.3 software and Stata 12.0 software were used for data analyses.RESULTS: Ten randomized controlled trials involving 1283 patients were included in this review; 678 subjects were in the proton pump inhibitors (PPI) group and the remaining 605 subjects were in the H2 receptor antagonists (H2RA) group. The meta-analysis results revealed that after successful endoscopic therapy, compared with H2RA, PPI therapy had statistically significantly decreased the recurrent bleeding rate (OR = 0.36; 95%CI: 0.25-0.51) and receiving surgery rate (OR = 0.29; 95%CI: 0.09-0.96). There were no statistically significant differences in mortality (OR = 0.46; 95%CI: 0.17-1.23). However, significant heterogeneity was present in both the numbers of patients requiring blood transfusion after treatment [weighted mean difference (WMD), -0.70 unit; 95%CI: -1.64 - 0.25] and the time that patients remained hospitalized [WMD, -0.77 d; 95%CI: -1.87 - 0.34]. The Begg’s test (P = 0.283) and Egger’s test (P = 0.339) demonstrated that there was no publication bias in our meta-analysis.CONCLUSION: In patients with upper gastrointestinal bleeding after successful endoscopic therapy, compared with H2RA, PPI may be a more effective therapy. 相似文献

Background:The purpose of this study was to compare the clinical efficacy of robotic right colectomy (RRC) and laparoscopic right colectomy (LRC) in the treatment of right colon tumor.Methods:We systematically searched PubMed, Web of science, EMBASE ClinicalTrials.gov and Cochrane Central Register for studies (studies published between January 2011 and June 2020). The included studies compared the clinical efficacy of RRC and LRC in the treatment of right colon tumor, and analyzed the perioperative data.Results:Our meta-analysis included 10 studies involving 1180 patients who underwent 2 surgical procedures, RRC and LRC. This study showed that compared with LRC, there was no significant difference in first flatus passage (weighted mean difference [WMD]: −0.37, 95% CI: −1.09–0.36, P = .32), hospital length of stay (WMD: −0.23, 95% CI: −0.73–0.28, P = .32), reoperation (OR: 1.66, 95% CI: 0.67–4.10, P = .27), complication (OR: 0.83, 95% CI: 0.60–1.14, P = .25), mortality (OR: 0.45, 95% CI: 0.02–11.22, P = .63), wound infection (OR: 0.65, 95% CI: 0.34–1.25, P = .20), and anastomotic leak (OR: 0.73, 95% CI: 0.33–1.63, P = .44). This study showed that compared with LRC, the lymph nodes retrieved (WMD: 1.47, 95% CI: −0.00–2.94, P = .05) of RRC were similar, with slight advantages, and resulted in longer operative time (WMD: 65.20, 95% CI: 53.40–77.01, P < .00001), less estimated blood loss (WMD: −13.43, 95% CI: −20.65–6.21, P = .0003), and less conversion to open surgery (OR: 0.30, 95% CI: 0.17–0.54, P < .0001).Conclusions:RRC is equivalent to LRC with respect to first flatus passage, hospital length of stay, reoperation, complication, and results in less conversion to LRC. 相似文献

Background
The clinical outcomes of drug-eluting stents versus bare-metal stents in end-stage renal disease patients remains controversial.Methods
A comprehensive literature search of Pubmed, Embase and Cochrane Library from January 2000 until November 2016 was conducted to identify relevant articles. We pooled the odds ratios (OR) from individual studies and conducted heterogeneity, quality assessment and publication bias analyses.Results
A total of 18 studies with 44,194 patients were identified. Compared with bare-metal stent-treated patients, drug-eluting stent-treated patients had significantly lower short-term and long-term all-cause mortality (OR = 0.56; 95% CI: 0.48-0.65; P < 0.00001; OR = 0.78; 95% CI: 0.66-0.92; P = 0.004, respectively), myocardial infarction (OR = 0.69; 95% CI: 0.53-0.88; P = 0.003) and major adverse cardiac events (OR = 0.72; 95% CI: 0.58-0.90; P = 0.004), with no detectable difference regarding stent thrombosis (OR = 0.80; 95% CI: 0.43-1.49; P = 0.47), cardiac mortality (OR = 0.95; 95% CI: 0.89-1.02; P = 0.14) and repeat revascularization (OR = 0.81; 95% CI: 0.62-1.06; P = 0.13).Conclusions
In patients with end-stage renal disease, the use of drug-eluting stents could significantly reduce the rates of mortality, myocardial infarction and major adverse cardiac events without increased risk of stent thrombosis. It poses imperative demands for future prospective randomized studies to define the optimal stent choice in this high-risk population. 相似文献9.

AIM:To compare the liver transplantation-free(LTF)survival rates between patients who underwent transjugular intrahepatic portosystemic shunts(TIPS)and those who underwent paracentesis by an updated meta-analysis that pools the effects of both number of deaths and time to death.METHODS:MEDLINE,EMBASE,and the Cochrane Library were searched from the inception to October2012.LTF survival,liver transplantation,liver diseaserelated death,non-liver disease-related death,recurrent ascites,hepatic encephalopathy(HE)and severe HE,and hepatorenal syndrome were assessed as outcomes.LTF survival was estimated using a HR with a95%CI.Other outcomes were estimated using OR with95%CIs.Sensitivity analyses were performed to assess the effects of potential outliers in the studies according to the risk of bias and the study characteristics.RESULTS:Six randomized controlled trials with 390patients were included.In comparison to paracentesis,TIPS significantly improved LTF survival(HR=0.61,95%CI:0.46-0.82,P<0.001).TIPS also significantly decreased liver disease-related death(OR=0.62,95%CI:0.39-0.98,P=0.04),recurrent ascites(OR=0.15,95%CI:0.09-0.24,P<0.001)and hepatorenal syndrome(OR=0.32,95%CI:0.12-0.86,P=0.02).However,TIPS increased the risk of HE(OR=2.95,95%CI:1.87-4.66,P=0.02)and severe HE(OR=2.18,95%CI:1.27-3.76,P=0.005).CONCLUSION:TIPS significantly improved the LTF survival of cirrhotic patients with refractory ascites and decreased the risk of recurrent ascites and hepatorenal syndrome with the cost of increased risk of HE compared with paracentesis.Further studies are warranted to validate the survival benefit of TIPS in clinical practice settings. 相似文献

AIM: To conduct a meta-analysis to determine the safety and efficacy of laparoscopic liver resection (LLR) and open liver resection (OLR) for hepatocellular carcinoma (HCC).METHODS: PubMed (Medline), EMBASE and Science Citation Index Expanded and Cochrane Central Register of Controlled Trials in the Cochrane Library were searched systematically to identify relevant comparative studies reporting outcomes for both LLR and OLR for HCC between January 1992 and February 2012. Two authors independently assessed the trials for inclusion and extracted the data. Meta-analysis was performed using Review Manager Version 5.0 software (The Cochrane Collaboration, Oxford, United Kingdom). Pooled odds ratios (OR) or weighted mean differences (WMD) with 95%CI were calculated using either fixed effects (Mantel-Haenszel method) or random effects models (DerSimonian and Laird method). Evaluated endpoints were operative outcomes (operation time, intraoperative blood loss, blood transfusion requirement), postoperative outcomes (liver failure, cirrhotic decompensation/ascites, bile leakage, postoperative bleeding, pulmonary complications, intraabdominal abscess, mortality, hospital stay and oncologic outcomes (positive resection margins and tumor recurrence).RESULTS: Fifteen eligible non-randomized studies were identified, out of which, 9 high-quality studies involving 550 patients were included, with 234 patients in the LLR group and 316 patients in the OLR group. LLR was associated with significantly lower intraoperative blood loss, based on six studies with 333 patients [WMD: -129.48 mL; 95%CI: -224.76-(-34.21) mL; P = 0.008]. Seven studies involving 416 patients were included to assess blood transfusion requirement between the two groups. The LLR group had lower blood transfusion requirement (OR: 0.49; 95%CI: 0.26-0.91; P = 0.02). While analyzing hospital stay, six studies with 333 patients were included. Patients in the LLR group were found to have shorter hospital stay [WMD: -3.19 d; 95%CI: -4.09-(-2.28) d; P < 0.00001] than their OLR counterpart. Seven studies including 416 patients were pooled together to estimate the odds of developing postoperative ascites in the patient groups. The LLR group appeared to have a lower incidence of postoperative ascites (OR: 0.32; 95%CI: 0.16-0.61; P = 0.0006) as compared with OLR patients. Similarly, fewer patients had liver failure in the LLR group than in the OLR group (OR: 0.15; 95%CI: 0.02-0.95; P = 0.04). However, no significant differences were found between the two approaches with regards to operation time [WMD: 4.69 min; 95%CI: -22.62-32 min; P = 0.74], bile leakage (OR: 0.55; 95%CI: 0.10-3.12; P = 0.50), postoperative bleeding (OR: 0.54; 95%CI: 0.20-1.45; P = 0.22), pulmonary complications (OR: 0.43; 95%CI: 0.18-1.04; P = 0.06), intra-abdominal abscesses (OR: 0.21; 95%CI: 0.01-4.53; P = 0.32), mortality (OR: 0.46; 95%CI: 0.14-1.51; P = 0.20), presence of positive resection margins (OR: 0.59; 95%CI: 0.21-1.62; P = 0.31) and tumor recurrence (OR: 0.95; 95%CI: 0.62-1.46; P = 0.81).CONCLUSION: LLR appears to be a safe and feasible option for resection of HCC in selected patients based on current evidence. However, further appropriately designed randomized controlled trials should be undertaken to ascertain these findings. 相似文献

Background: Minimal hepatic encephalopathy(MHE) is an early and reversible form of hepatic encephalopathy. The documentations on the treatment with probiotics are inconsistent. The present meta-analysis was to verify the role of probiotics in the treatment of cirrhotic patients with MHE.Data sources: Seven electronic databases were searched for relevant randomized controlled trials(RCTs)published until July 2015. The effects of probiotics on serum ammonia, endotoxin, and MHE were evaluated.Results: A total of 14 RCTs(combined n = 1132) were included in the meta-analysis. When probiotics were compared to placebo or no treatment, probiotics were more likely to reduce values in the number connection test(NCT; week 4: MD =-30.25, 95% CI:-49.85 to-10.66), improve MHE(week 4: OR = 0.18,95% CI: 0.07 to 0.47; week 12: OR = 0.15, 95% CI: 0.07 to 0.32), and prevent overt HE progression(week4: OR = 0.22, 95% CI: 0.07 to 0.67) in patients with liver cirrhosis. When probiotics was compared to lactulose, probiotics tended to reduce serum ammonia levels(week 4: MD =-0.33 μmol/L, 95% CI:-5.39 to 4.74; week 8: MD = 6.22 μmol/L, 95% CI:-24.04 to 36.48), decrease NCT(week 8: MD = 3.93, 95% CI:-0.72 to 8.58), improve MHE(week 4: OR = 0.93, 95% CI: 0.45 to 1.91; week 12: OR = 0.73, 95% CI: 0.35 to 1.51) and prevent the development of overt HE(week 4: OR = 0.96, 95% CI: 0.17 to 5.44; week 12:OR = 2.7, 95% CI: 0.50 to 14.64) in patients with liver cirrhosis. However, lactulose appears to be more effective in reducing NCT values as compared to probiotics(week 4: MD = 6.7, 95% CI: 0.58 to 12.82).Conclusion: Probiotics can decrease serum ammonia and endotoxin levels, improve MHE, and prevent overt HE development in patients with liver cirrhosis. 相似文献

Background:The purpose of the present meta-analysis was to compare the efficacy of rifaximin and nonabsorbable disaccharides (NADs) in hepatic encephalopathy (HE).Methods:After the registration of the present meta-analysis on INPLASY, all procedures were performed according to PRISMA 2020. Relevant literature was retrieved on PubMed, Embase, and the Cochrane Library up to September 5, 2021. The Newcastle-Ottawa Scale (NOS) was used to assess the quality of the enrolled studies, and Review Manager software (version 5.3) was used to analyze the clinical efficacy, blood ammonia and adverse effects.Results:Six studies with 559 patients were included in the present meta-analysis. There were no significant differences in the basic characteristics of the included studies. Analysis of the complete resolution of HE showed that rifaximin was better than NADs (risk ratio [RR] = 1.87, 95% confidence interval [CI] = 1.03–3.39, P = .04). However, there were no significant differences in mental status (RR = 1.04, 95% CI = 0.92–1.18, P = .53), blood ammonia level (standard mean difference = −0.02, 95% CI = −0.40–0.02, P = .08), or drug adverse drug effects (OR = 0.43, 95% CI = 0.10–1.77, I2 = 56%, P = .24) between the rifaximin and NADs treatment groups.Conclusion:Rifaximin is not superior to NADs in the treatment of HE. 相似文献

BackgroundSurgical resection is the only possible cure for pancreatic cancer, it remains controversial whether extend lymphadenectomy in pancreatoduodenectomy (EPD) is better than standard lymphadenectomy in pancreatoduodenectomy (SPD). The aim of this study was to compare the efficacy of EPD with SPD for pancreatic head adenocarcinoma.MethodsA specific search of online databases including PubMed, Web of Science, Embase, and Cochrane library was conducted from January 1990 to October 2018. Relative perioperative outcomes were synthesized. Single-arm meta-analysis was also performed.ResultsA total of eight studies involving 687 (342 vs 345) patients were included for analysis in our study. The number of lymph nodes harvested [24.54 vs 13.29; weighted mean difference (WMD) ?10.69, P = 0.000], operative time (469.84 min vs 354.85 min; WMD -99.09, P = 0.000), and diarrhea (postoperative three months) [45.1% vs 18.2%; odds radio (OR) 0.20, P = 0.014] were significantly higher in patients who underwent EPD than SPD. The perioperative complications (35% vs 28.8%; OR 0.79, P = 0.186), tumor size (3.27 cm vs 3.248 cm; WMD -0.11, P = 0.256), lymph node metastasis (66% vs 55.9%; OR 0.71, P = 0.105), and positive margin (10.4% vs 11.3%; OR 1.28, P = 0.392) were no significant differences between EPD group and SPD group. Extended lymphadenectomy in pancreatoduodenectomy dose not contribute to the overall survival of patients with adenocarcinoma of the pancreatic head [hazard ratio (HR) 0.95; 95% CI 0.78–1.15; P = 0.61].ConclusionThe update meta-analysis shows that EPD failed to improve the overall survival, may even lead to increased morbidity. 相似文献

BackgroundHypertension is the major attributable risk factor for cardiovascular disease. The effect of Tai Chi on essential hypertension (EH) is contentious.ObjectivesIn this study, we investigated the effects of Tai Chi on the risk factors for cardiovascular disease and quality of life in adults with EH.MethodsUsing data collected from 15 databases up to December 2018, we meta-analyzed randomized controlled trials of the effect of Tai Chi on EH.ResultsTai Chi exercise was associated with lower systolic blood pressure (SBP) (WMD −12.47, 95%CI −16.00 to −8.94, P < 0.001) and diastolic blood pressure (DBP) (WMD −6.46, 95%CI −8.28 to −4.64, P < 0.001); better quality of life (SMD 0.62, 95% CI 0.35 to 0.90, P < 0.001); lower lipid profiles, including total cholesterol (WMD −0.49, 95% CI −0.62 to −0.37, P < 0.001), triglycerides (WMD −0.49, 95% CI −0.92 to −0.07, P = 0.02), and low-density lipoprotein-cholesterol (LDL-C) (WMD −0.86, 95% CI −1.30 to −0.43, P < 0.001); and lower blood glucose (WMD −0.91, 95% CI −1.59 to −0.23, P = 0.009). Tai Chi had no significant effect on high-density lipoprotein–cholesterol (WMD −0.92, 95% CI −2.21 to −0.37, P = 0.16).ConclusionsTai Chi lowers blood pressure, total cholesterol, triglycerides, LDL-C, and blood glucose and significantly increases the quality of life in adults with EH. There is strong evidence for the short-term efficacy of Tai Chi exercises. Larger well-designed RCTs focused on the long-term effect of Tai Chi exercises and patient adherence are needed. 相似文献

AIM: To investigate the contribution of polymorphisms in nuclear receptors to risk of inflammatory bowel disease (IBD).METHODS: Genotypes of nuclear factor (NF)-κB (NFKB1) NFκB -94ins/del (rs28362491); peroxisome proliferator-activated receptor (PPAR)-γ (PPARγ) PPARγ Pro12Ala (rs 1801282) and C1431T (rs 3856806); pregnane X receptor (PXR) (NR1I2) PXR A-24381C (rs1523127), C8055T (2276707), and A7635G (rs 6785049); and liver X receptor (LXR) (NR1H2) LXR T-rs1405655-C and T-rs2695121-C were assessed in a Danish case-control study of 327 Crohn’s disease patients, 495 ulcerative colitis (UC) patients, and 779 healthy controls. Odds ratio (OR) and 95% CI were estimated by logistic regression models.RESULTS: The PXR A7635G variant, the PPARγ Pro12Ala and LXR T-rs2695121-C homozygous variant genotypes were associated with risk of UC (OR: 1.31, 95% CI: 1.03-1.66, P = 0.03, OR: 2.30, 95% CI: 1.04-5.08, P = 0.04, and OR: 1.41, 95% CI: 1.00-1.98, P = 0.05, respectively) compared to the corresponding homozygous wild-type genotypes. Among never smokers, PXR A7635G and the LXR T-rs1405655-C and T-rs2695121-C variant genotypes were associated with risk of IBD (OR: 1.41, 95% CI: 1.05-1.91, P = 0.02, OR: 1.63, 95% CI: 1.21-2.20, P = 0.001, and OR: 2.02, 95% CI: 1.36-2.99, P = 0.0005, respectively) compared to the respective homozygous variant genotypes. PXR A7635G (rs6785049) variant genotype was associated with a higher risk of UC diagnosis before the age of 40 years and with a higher risk of extensive disease (OR: 1.34, 95% CI: 1.03-1.75 and OR: 2.49, 95% CI: 1.24-5.03, respectively).CONCLUSION: Common PXR and LXR polymorphisms may contribute to risk of IBD, especially among never smokers. 相似文献

Background/Aim:
Erythromycin infusion before endoscopy in upper gastrointestinal bleeding (UGIB) has been hypothesized to aid in visualization and reduce the need for second-look endoscopy; however, the results have been controversial. To evaluate further, we performed a meta-analysis comparing the efficacy of erythromycin infusion before endoscopy in acute UGIB.Methods:
Multiple databases were searched (March 2013). Only randomized controlled trials were included in the analysis. A meta-analysis for the effect of erythromycin or no erythromycin before endoscopy in UGIB were analyzed by calculating pooled estimates of primary (visualization of gastric mucosa and need for second endoscopy) and secondary (units of blood transfused, length of hospital stay, duration of the procedure) outcomes. Statistical analysis was performed using RevMan 5.1 (Copenhagen: The Nordic Cochrane Centre, The Cochrane Collaboration).Results:
Six studies (N = 558) met the inclusion criteria. Erythromycin infusion before endoscopy in UGIB demonstrated a statistically significant improvement in visualization of the gastric mucosa [odds ratio (OR) 3.43; 95% confidence interval (CI): 1.81 to 6.50, P < 0.01] compared with no erythromycin. In addition, erythromycin infusion before endoscopy resulted in a statistically significant decrease in the need for a second endoscopy (OR 0.47; 95% CI: 0.26 to 0.83, P = 0.01), units of blood transfused (WMD − 0.41; 95% CI: −0.82 to −0.01, P = 0.04), and the duration of hospital stay (WMD − 1.51; 95% CI: −2.45 to −0.56, P < 0.01).Conclusions:
Erythromycin infusion before endoscopy in patients with UGIB significantly improves visualization of gastric mucosa while decreasing the need for a second endoscopy, units of blood transfused, and duration of hospital stay. 相似文献20.

BackgroundThe risks of thromboembolic and hemorrhagic events in patients with atrial fibrillation both increase with age; therefore, net clinical benefit analyses of anticoagulant treatments in the elderly population are crucial to guide treatment. We evaluated the 1-year clinical outcomes with non-vitamin-K antagonist and vitamin K antagonist oral anticoagulants (NOACs vs VKAs) in elderly (≥75 years) patients with atrial fibrillation in a prospective registry setting.MethodsData on 3825 elderly patients were pooled from the PREFER in AF and PREFER in AF PROLONGATION registries. The primary outcome was the incidence of the net composite endpoint, including major bleeding and ischemic cardiovascular events on NOACs (n = 1556) compared with VKAs (n = 2269).ResultsThe rates of the net composite endpoint were 6.6%/year with NOACs vs 9.1%/year with VKAs (odds ratio [OR] 0.71; 95% confidence interval [CI], 0.51-0.99; P = .042). NOAC therapy was associated with a lower rate of major bleeding compared with VKA use (OR 0.58; 95% CI, 0.38-0.90; P = .013). Ischemic events were nominally reduced too (OR 0.71; 95% CI, 0.51-1.00; P = .050). Major bleeding with NOACs was numerically lower in higher-risk patients with low body mass index (BMI; OR 0.50; 95% CI, 0.22-1.12; P = .07) or with age ≥85 years (OR 0.44; 95% CI, 0.13-1.49; P = .17).ConclusionsOur real-world data indicate that, compared with VKAs, NOAC use is associated with a better net clinical benefit in elderly patients with atrial fibrillation, primarily due to lower rates of major bleeding. Major bleeding with NOACs was numerically lower also in higher-risk patients with low BMI or age ≥85 years. 相似文献
