Epstein-Barr virus (EBV) is an ubiquitous human herpes virus with worldwide distribution. Severe EBV infections are mostly reported in immunocompromised patients, but not in immunocompetent individuals. Here, we reported an immunocompetent female adult suffering from an acute EBV pulmonary infection, leading to bilateral pneumonitis with respiratory failure. This case indicated combined therapy (steroids, immunoglobulin and antiviral agents) is recommended in EBV-induced severe respiratory insufficiency. © 2017, E-Century Publishing Corporation.

The effect of glucagon-like peptide-1(GLP-1) receptor agonists on heart failure remains uncertain. We therefore conducted a systematic review to assess the possible impact of GLP-1 agonists on heart failure or hospitalization for heart failure in patients with type 2 diabetes.We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL) and ClinicalTrials.gov to identify randomized controlled trials (RCTs) and observational studies that addressed the effect of GLP-1 receptor agonists in adults with type 2 diabetes, and explicitly reported heart failure or hospitalization for heart failure. Two paired reviewers screened reports, collected data, and assessed the risk of bias. We pooled data from RCTs and observational studies separately, and used the GRADE approach to rate the quality of evidence.We identified 25 studies that were eligible for our review; 21 RCTs (n = 18,270) and 4 observational studies (n = 111,029). Low quality evidence from 20 RCTs suggested, if anything, a lower incidence of heart failure between GLP-1 agonists versus control (17/7,441 vs. 19/4,317; odds ratio (OR) 0.62, 95 % confidence interval (CI) 0.31 to 1.22; risk difference (RD) 19 fewer, 95 % CI 34 fewer to 11 more per 1000 over 5 years). Three cohort studies comparing GLP-1 agonists to alternative agents provided very low quality evidence that GLP-1 agonists do not increase the incidence of heart failure. One RCT provided moderate quality evidence that GLP-1 agonists were not associated with hospitalization for heart failure (lixisenatide vs placebo: 122/3,034 vs. 127/3,034; adjusted hazard ratio 0.96, 95 % CI 0.75 to 1.23; RD 4 fewer, 95 % CI 25 fewer to 23 more per 1000 over 5 years) and a case-control study provided very low quality evidence also suggesting no association (GLP-1 agonists vs. other anti-hyperglycemic drugs: 1118 cases and 17,626 controls, adjusted OR 0.67, 95 % CI 0.32 to 1.42).The current evidence suggests that GLP-1 agonists do not increase the risk of heart failure or hospitalization for heart failure among patients with type 2 diabetes.

To examine the association between dipeptidyl peptidase-4 (DPP-4) inhibitors and the risk of heart failure or hospital admission for heart failure in patients with type 2 diabetes.Systematic review and meta-analysis of randomised and observational studies.Medline, Embase, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov searched up to 25 June 2015, and communication with experts.Randomised controlled trials, non-randomised controlled trials, cohort studies, and case-control studies that compared DPP-4 inhibitors against placebo, lifestyle modification, or active antidiabetic drugs in adults with type 2 diabetes, and explicitly reported the outcome of heart failure or hospital admission for heart failure.Teams of paired reviewers independently screened for eligible studies, assessed risk of bias, and extracted data using standardised, pilot tested forms. Data from trials and observational studies were pooled separately; quality of evidence was assessed by the GRADE approach.Eligible studies included 43 trials (n=68,775) and 12 observational studies (nine cohort studies, three nested case-control studies; n=1,777,358). Pooling of 38 trials reporting heart failure provided low quality evidence for a possible similar risk of heart failure between DPP-4 inhibitor use versus control (42/15,701 v 33/12,591; odds ratio 0.97 (95% confidence interval 0.61 to 1.56); risk difference 2 fewer (19 fewer to 28 more) events per 1000 patients with type 2 diabetes over five years). The observational studies provided effect estimates generally consistent with trial findings, but with very low quality evidence. Pooling of the five trials reporting admission for heart failure provided moderate quality evidence for an increased risk in patients treated with DPP-4 inhibitors versus control (622/18,554 v 552/18,474; 1.13 (1.00 to 1.26); 8 more (0 more to 16 more)). The pooling of adjusted estimates from observational studies similarly suggested (with very low quality evidence) a possible increased risk of admission for heart failure (adjusted odds ratio 1.41, 95% confidence interval 0.95 to 2.09) in patients treated with DPP-4 inhibitors (exclusively sitagliptin) versus no use.The relative effect of DPP-4 inhibitors on the risk of heart failure in patients with type 2 diabetes is uncertain, given the relatively short follow-up and low quality of evidence. Both randomised controlled trials and observational studies, however, suggest that these drugs may increase the risk of hospital admission for heart failure in those patients with existing cardiovascular diseases or multiple risk factors for vascular diseases, compared with no use.

Aim and background. High-grade gastrointestinal neuroendocrine neoplasms, ie, poorly differentiated neuroendocrine carcinomas, with no effective therapeutic approaches, have a high ability to metastasize. Methods. A review of the hospital information system was performed. Patients with histologically proven gastrointestinal neuroendocrine carcinoma who were treated with irinotecan combined with 5-fluorouracil and leucovorin in a first-line setting were eligible for analysis. We extracted information on age, sex, disease stage, laboratory findings, radiological findings, pathological findings, chemotherapy, effectiveness and adverse events of therapy, and outcomes. Results. Eleven patients were included in the study. Partial response was observed in 7 patients. Median progression-free survival and overall survival were 6.5 (95% CI, 5.1-7.9) and 13.0 (95% CI, 9.8-16.2) months, respectively. No treatment-related deaths occurred. Conclusions. The results demonstrated that irinotecan combined with 5-fluorouracil and leucovorin is an active regimen with acceptable toxicity for patients with metastatic high-grade gastointestinal neuroendocrine carcinoma that merits further investigation in prospective trials.

Objectives: To evaluate the efficacy and safety of radiofrequency ablation (RFA) versus hepatic resection (HR) for early hepatocellular carcinoma (HCC) meeting the Milan criteria. Methods: A meta-analysis was conducted, and PubMed, Web of Science, the Cochrane Library, CBM, CNKI and VIP databases were systematically searched through November 2012 for randomized and nonrandomized controlled trials (RCTs and NRCTs). The Cochrane Collaboration's tool and modified MINORS score were applied to assess the quality of RCTs and NRCTs, respectively. The GRADE approach was employed to evaluate the strength of evidence. Results: Three RCTs and twenty-five NRCTs were included. Among 11,873 patients involved, 6,094 patients were treated with RFA, and 5,779 with HR. The pooled results of RCTs demonstrated no significant difference between groups for 1- and 3-year overall survival (OS), recurrence-free survival (RFS) and disease-free survival (DFS) (p.0.05). The 5-year OS (Relative Risk, RR 0.72, 95% CI 0.60 to 0.88) and RFS (RR 0.56, 95% CI 0.40 to 0.78) were lower with RFA than with HR. The 3- and 5-year recurrences with RFA were higher than with HR (RR 1.48, 95% CI 1.14 to 1.94, and RR 1.52, 95% CI 1.18 to 1.97, respectively), but 1-year recurrence and in-hospital mortality showed no significant differences between groups (p.0.05). The complication rate (RR 0.18, 95% CI 0.06 to 0.53) was lower and hospital stays (Mean difference -8.77, 95% CI 210.36 to 27.18) were shorter with RFA than with HR. The pooled results of NRCTs showed that the RFA group had lower 1-, 3- and 5- year OS, RFS and DFS, and higher recurrence than the HR group (p,0.05). But for patients with very early stage HCC, RFA was comparable to HR for OS and recurrence. Conclusion: The effectiveness of RFA is comparable to HR, with fewer complications but higher recurrence, especially for very early HCC patients. © 2014 Wang et al.

Objective: To explore the efficacy and safety of high-intensity focused ultrasound combined with other physical therapies for the treatment of pancreatic cancer, so as to provide reference for clinical application. Methods: The PubMed, EMbase, The Cochrane Library (Issue 11, 2013), CBM, CNKI, and WanFang databases were systematically searched up to November 2013. The randomized controlled trials and clinical controlled trials about the treatment of high-intensity focused ultrasound were included. According to the inclusion and exclusion criteria, two reviewers independently screened the studies, exacted the data, and assessed the quality. The meta-analysis was performed by using the RevMan 5.0 software. Results: A total of 23 studies including 19 randomized controlled trials and four clinical controlled trials were included. Of which 14 studies reported the safety. The results of meta-analyses showed that: the survival rate at 6 months and 12 months, overall efficacy, and clinical benefit rate in high-intensity focused ultrasound plus radiation and chemotherapy group were significantly higher than those in groups treated with three-dimensional conformal radiation therapy (P < 0.05), gemcitabine (P < 0.05), gemcitabine plus cisplatin (P < 0.05), and gemcitabine plus 5-fluorouracil (P < 0.05). The adverse effect caused by high-intensity focused ultrasound plus other therapy was equal to those in the control group. The major high-intensity focused ultrasound-related adverse effect was skin damage and fever. Conclusion: The current evidence suggested that the efficacy of high-intensity focused ultrasound for pancreatic cancer was superior to other therapies. However, the poor quality of trails may reduce the reliability of outcome to some extent. The current evidence suggested that the efficacy of HIFU for pancreatic cancer was superior to other therapies, but with poor quality. Therefore, a standard and unified criterion for the diagnosis and outcome measures of pancreatic cancer is needed, and the quality of study design and implementation should be bettered, so as to improve the high quality of evidence for its clinical application. © 2014 Chinese Cochrane Center, West China Hospital of Sichuan University and Wiley Publishing Asia Pty Ltd.

The aim of the present study was to perform a retrospective analysis to investigate the outcome and toxicity of radiation (RT) and chemoradiation (CRT) in elderly, inoperable patients >70 years old. Between 2003 and 2012, 1,024 patients with squamous cell carcinoma (SCC) of the esophagus were treated at the Department of Thoracic Cancer, West China Hospital (Chengdu, China). Of these patients, 37 were >70 years old and had not undergone surgery, and were selected for analysis. Of these 37 patients, CRT had been administered to 20 (54%). Actuarial survival rates were determined by the Kaplan-Meier method. The one-year survival rate in the CRT group (n=20) was 85%, while 35% of patients in the RT group (n=17) survived for more than one year. The overall and progression-free survival in the CRT group versus the RT group were 17 months [95% confidence interval (CI), 11.861-22.139] versus eight months (95% CI, 6.674-9.326) (P=0.013) and 14 months (95% CI, 9.617-18.383) versus five months (95% CI, 2.311-7.689) (P=0.01), respectively. Patients irradiated with a dose of >50 Gy exhibited an improved survival rate compared with patients who received a dose of ≤50 Gy (18 vs. 14 months; P=0.049). Furthermore, patients with an Eastern Cooperative Oncology Group (ECOG) score of ≤1 had an improved prognosis compared with those with an ECOG score of 2 (14 vs. seven months; P=0.006). The two regimens were well-tolerated and there were no therapy-associated mortalities. The current retrospective study indicated that patients of >70 years old with inoperable esophageal SCC and a good ECOG score exhibit comparably better safety levels with CRT and improved survival rates compared with RT alone.

Receptor for advanced glycation end products (RAGE), a multiligand receptor, has been suggested to be implicated in inflammatory response. However, its role in chronic obstructive pulmonary disease (COPD) has not been well elucidated. Recently, several studies reported RAGE and its common ligands were upregulated in airways and lung tissues from COPD smokers. Moreover, inhibition of RAGE activation significantly attenuated cigarette smoke extract or bacteria-induced pulmonary inflammation. Based on these findings, a conclusion could be made that ligand-activated RAGE may play a key role in COPD and thus RAGE could be a new therapeutic target for COPD. © 2013 IMSS.

Purpose: To evaluate the clinical efficacy and toxicity of stereotactic body radiation therapy (SBRT) using extracranial gamma knife in patients with mainly bulky inoperable early stage non-small cell lung carcinoma (NSCLC).Materials and methods: A total of 43 medically inoperable patients with mainly bulky Stage I/II NSCLC received SBRT using gamma knife were reviewed. The fraction dose and the total dose were determined by the radiation oncologist according to patients' general status, tumor location, tumor size and the relationship between tumor and nearby organ at risk (OAR). The total dose of 34~47.5 Gy was prescribed in 4~12 fractions, 3.5~10 Gy per fraction, one fraction per day or every other day. The therapeutic efficacy and toxicity were evaluated.Results: The median follow-up was 22 months (range, 3-102 months). The local tumor response rate was 95.35%, with CR 18.60% (8/43) and PR 76.74% (33/43), respectively. The local control rates at 1, 2, 3, 5 years were 77.54%, 53.02%, 39.77%, and 15.46%, respectively, while the 1- and 2-year local control rates were 75% and 60% for tumor ≤3 cm; 84% and 71% for tumor sized 3~5 cm; 55% and 14.6% for tumor sized 5~7 cm; and 45%, 21% in those with tumor size of >7 cm. The overall survival rate at 1, 2, 3, 5 years were 92.04%, 78.04%, 62.76%, 42.61%, respectively. The toxicity of stereotactic radiation therapy was grade 1-2. Clinical stages were significantly important factor in local control of lung tumors (P = 0.000). Both clinical stages (P = 0.015) and chemotherapy (P = 0.042) were significantly important factors in overall survival of lung tumors.Conclusion: SBRT is an effective and safe therapy for medically inoperable patients with early stage NSCLC. Clinical stage was the significant prognostic factors for both local tumor control and overall survival. The toxicity is mild. The overall local control for bulky tumors is poor. Tumor size is a poor prognostic factor, and the patients for adjuvant chemotherapy need to be carefully selected. © 2011 Wu et al; licensee BioMed Central Ltd.

Objectives: To evaluate the quality of pancreatic cancer guidelines with evidence-based methods based on the global burden of disease and to explore its status, distribution, characteristics of theme, and the difference of recommended therapies among various qualities of guidelines, so as to provide a reference for clinical decision. Methods: The PubMed, The Cochrane Library (Issue 11, 2013), Chinese Biomedical Database, China National Knowledge Infrastructure, and VIP databases, as well as the website of National Guidelines Clearinghouse, Guidelines International Network, and National Institute for Clinical Excellence were systematically reviewed through November 2013 for pancreatic cancer guidelines. The Appraisal of Guidelines for Research and Evaluation (AGREE II) were applied to assess the methodological quality of the guidelines. Results: A total of 14 relevant guidelines (including 5 evidence-based ones) were identified, involving four continents (Asia, Europe, North America, and Oceania), seven counties, and four international organizations. There were only two domains, namely 'scope and purpose' and 'clarity of presentations', getting high average scores (more than 60%) among all 14 guidelines. The mean AGREE domain score in guidelines varies among different areas, and the quality of 5 evidence-based guidelines was superior to that established by consensus. According to AGREE II, 11 guidelines were weakly recommended, while 3 were not recommended due to poor methodological quality. Their subjects of 14 guidelines covered six treatment categories, including chemotherapy, surgery, radiotherapy, support therapy, radiotherapy, and interventional therapy. Conclusion: The overall methodological quality of pancreatic cancer guidelines is suboptimal among different countries or regions. The qualities of evidence-based guidelines are significantly superior to consensus. The chemotherapy, surgery, radiotherapy, and support therapy were the predominant choices by guidelines. © 2015 Chinese Cochrane Center, West China Hospital of Sichuan University and Wiley Publishing Asia Pty Ltd.
