Endoscopic versus Surgical Intervention for Painful Obstructive Chronic Pancreatitis: A Systematic Review and Meta-Analysis

There is limited evidence on the standard care for painful obstructive chronic pancreatitis (CP), while comparisons of endoscopic and surgical modes for pain relief have yielded conflicting results from small sample sizes. We aimed to obtain a clear picture of the matter by a meta-analysis of these results. We searched the Pubmed, Embase, and Cochrane Library databases to identify studies comparing endoscopic and surgical treatments for painful obstructive CP. Pooled effects were calculated by the random effect model. Primary outcomes were overall pain relief (complete and partial), and secondary outcomes were complete and partial pain relief, complication rate, hospitalization duration, and endocrine insufficiency. Seven studies with 570 patients were included in the final analysis. Surgical drainage was associated with superior overall pain relief [OR 0.33, 95% CI 0.23–0.47, p < 0.001, I2 = 4%] and lesser incidence of endocrine insufficiency [OR 2.10, 95% CI 1.20–3.67, p = 0.01, I2 = 0%], but no significant difference in the subgroup of complete [OR 0.57, 95% CI 0.32–1.01, p = 0.054, I2 = 0%] or partial [OR 0.67, 95% CI 0.37–1.22, p = 0.19, I2 = 0%] pain relief, complication rates [OR 1.00, 95% CI 0.41–2.46, p = 0.99, I2 = 49%], and hospital stay [OR −0.54, 95% CI −1.23–0.15, p = 0.13, I2 = 87%] was found. Surgery is associated with significantly better overall pain relief and lesser endocrine insufficiency in patients with painful obstructive CP. However, considering the invasiveness of surgery, no significant differences in complete or partial pain relief, and heterogeneity of a few parameters between two groups, endoscopic drainage may be firstly performed and surgical drainage may be considered when endoscopic drainage fails.

Abstract Background Clinical practice with aromatherapy has become an expanding area for nursing, and is considered one of the most popularly used complementary treatments. However, there is insufficient evidence about the benefits of aromatherapy for pain management and other related discomforts in labor. We aimed to evaluate the effects of aromatherapy for women during delivery particularly for pain relief. Methods AMED, ClinicalTrials.Gov, CINAHL, Cochrane Library, EMBASE, MEDLINE, PubMed, and WHO ICTRP were searched in August 2017. For updates, these databases were searched from July 2017 to July 2018. This study included randomized controlled trials (RCTs) and quasi-RCTs for normal pregnancy women who were experiencing labor onset, and compared aromatherapy with standard care or control. Results Six RCTs from six reports, and four quasi-RCTs from five reports were included (1238 pregnant women). The trials found significant difference between groups for the primary outcomes of pain relief on the latent (MD -1.56, 95%CI: -2.45 to -0.67, low certainty of evidence) and early active phase (MD -1.69, 95%CI: -2.50 to -0.89, low certainty of evidence). However, there were no significant differences for the primary outcomes of pain relief on the late active phase, and anxiety relief on the early and late active phases. Conclusions This meta-analysis found evidence that the use of inhalation aromatherapy for term pregnancy women is associated with reduction of labor pain. However, there is insufficient evidence to confirm pain relief on the late active phase, anxiety relief, and other outcomes following aromatherapy. Trial registration We registered the study protocol with PROSPERO (CRD42017077617).

Vitamins C and E can act as potent antioxidants to reduce the damage caused by reactive oxygen species in gastric mucosa. Whether vitamin supplements forHelicobacter pylorieradication regimen could improve the rate of eradication remains uncertain. Therefore, we performed a meta-analysis to evaluate the efficacy of vitamins C and E supplementation for the eradication ofH. pylori. Searches were conducted in the databases PubMed, EMBASE and Cochrane Library. Randomised controlled trials (RCT) that fulfilled the inclusion criteria and addressed the clinical questions of this analysis were further assessed. Of the six RCT included, five had a low methodological quality. Of the six RCT, three compared the efficacy of the eradication regimenv.eradication regimen plus vitamins C and E. The result of the meta-analysis showed a non-significant difference in the eradication rate ofH. pyloribetween the two groups (risk ratio (RR) 0·93,P = 0·76). Another three RCT compared the eradication regimenv.eradication regimen plus vitamin C only, and there too there was no significant difference in the eradication rate (RR 0·83,P = 0·32). In conclusion, vitamins C and/or E supplements to theH. pylorieradication regimen could not improve the eradication rate. However, currently available data do not draw a definitive conclusion about the effectiveness of antioxidant vitamins onH. pylorieradication, owing to the small sample size and low-to-moderate methodological quality.

Objective To evaluate the effectiveness of early (<3 months) cranioplasty (CP) and late CP (>3 months) on post-operative complications in patients receiving decompressive craniotomy (DC) for traumatic brain injury (TBI). Methods The Cochrane Library, PubMed and EMBASE databases were systematically searched for studies published prior to May 21, 2017. A meta-analysis examined post-operative overall complication rates, infection rates, subdural fluid collection and operating times according to early and late CP. Results Of the initial 1675 references, five studies, all cohort, involving a total of 413 patients, were selected for the review. There was no difference between early and late CP in post-operative overall complication rate (RR=0.68, 95%CI [0.36, 1.29]) and the post-operative infection rate (RR=0.50, 95%CI [0.20, 1.24]) in patients receiving DC for TBI. However, there was a significant difference in post-operative subdural effusion (RR=0.24, 95%CI [0.07, 0.78]) and mean operative time (mean difference = −33.02 min, 95%CI [−48.19, −17.84]) both in favour of early CP. Conclusions No differences were found between early and late CP in post-operative overall complications and procedural related infections in patients receiving DC for TBI, but early CP reduced the complication of subdural effusion and the mean operating time. These findings need to be confirmed by large, randomised controlled trials.

Background. Staples closure technology has been widely used in total knee arthroplasty (TKA) and achieved good results. In recent years, a new type of material called skin closure tape (SCT) has been applied to TKA which also showed good treatment results. However, since it is still not clear yet which one is better, this paper collects literatures for statistical analysis so as to provide evidence for the use of SCT in TKA. Methods. The comparative study on effects between SCT and staples is reviewed after the primary release of TKA in PubMed, the Cochrane library, and the EMBASE database up to March 2019. The two researchers independently screened the literature and evaluated the quality of the literature using bias risk tools. Results. A total of four studies (3330 knees) have been included in our meta-analysis. For the main point, the results show that the SCT can reduce readmission rates compared to staples (RR 0.68, 95% CI 0.49–0.95, P=0.03), with no significant difference in complications (RR 0.85, 95% CI 0.27–2.64, P=0.77). Secondly, the results suggest that although there is no significant difference in removal time between the two groups, the SCT can reduce pains, save time and costs, and have a better cosmetic effect. Conclusions. Our study indicates SCT as a closure method with fewer complications and faster speed compared with staples. Nevertheless, the cost and pain need to be further confirmed because of the small sample size included in this study.

Pylorus-preserving pancreaticoduodenectomy (PPPD) and duodenum-preserving pancreatic head resection (DPPHR) are important treatment options for patients with chronic pancreatitis. This meta-analysis was undertaken to compare the long-term outcomes of DPPHR versus PPPD in patients with chronic pancreatitis. A systematic literature search was conducted using Embase, MEDLINE, Cochrane, and PubMed databases on all studies published between January 1991 and January 2013 reporting intermediate and long-term outcomes after DPPHR and PPPD for chronic pancreatitis. Long-term outcomes of interest were complete pain relief, quality of life, professional rehabilitation, exocrine insufficiency, and endocrine insufficiency. Other outcomes of interest included perioperative morbidity and length of stay (LOS). Ten studies were included comprising of 569 patients. There was no significant difference in complete pain relief ( P = 0.24), endocrine insufficiency ( P = 0.15), and perioperative morbidity ( P = 0.13) between DPPHR and PPPD. However, quality of life ( P < 0.00001), professional rehabilitation ( P = 0.004), exocrine insufficiency ( P = 0.005), and LOS ( P = 0.00001) were significantly better for patients undergoing DPPHR compared with PPPD. In conclusion, there is no significant difference in endocrine insufficiency, postoperative pain relief, and perioperative morbidity for patients undergoing DPPHR versus PPPD. Improved intermediate and long-term outcomes including LOS, quality of life, professional rehabilitation, and preservation of exocrine function make DPPHR a more favorable approach than PPPD for patients with chronic pancreatitis.

Background: The effectiveness of platelet-rich plasma (PRP) injections for knee osteoarthritis and the effects of leukocyte-poor PRP (LP-PRP) versus leukocyte-rich PRP (LR-PRP) are still controversial. Purpose: To assess the effectiveness of different PRP injections through a direct and indirect meta-analysis of randomized controlled trials. Study Design: Systematic review; Level of evidence, 1. Methods: A systematic literature search of electronic databases (PubMed, Cochrane Library, and EMBASE) was performed to locate randomized controlled trials published through March 2019 that compared PRP with control treatment. A random-effects meta-analysis was conducted to synthesize the evidence, and meta-regression analyses were conducted to determine the influence of trial characteristics. An indirect comparison was performed to assess the effects of LP-PRP and LR-PRP compared with hyaluronic acid (HA). Results: A total of 21 trials were included. A clinically important benefit for pain relief was seen for intra-articular PRP compared with intra-articular saline (standardized mean difference [SMD] = –1.38 [95% CI, –2.07 to –0.70]; P < .0001; I 2 = 37%) and corticosteroid solution injection (SMD = –2.47 [95% CI, –3.34 to –1.61]; P < .00001; I 2 = 47%). As a result of heterogeneity ( I 2 = 89%), there was no conclusive effect compared with HA, even though the pooling effect provided clinically relevant pain relief (SMD = –0.59 [95% CI, –0.97 to –0.21]; P = .003). Indirect meta-analysis showed that there was no significant difference between LR-PRP and LP-PRP. Conclusion: PRP injections are beneficial for pain relief and functional improvement in knee osteoarthritis. Larger, randomized high-quality studies are needed to compare the effects of LP-PRP and LR-PRP.

Abstract Backgroud Patient-controlled analgesia(PCA) with intravenous an opioid has been suggested as a effective method of postoperative pain relief. There are several randomized controlled trials (RCTs) of comparison of oxycodone and fentanyl for IV-PCA in surgical patients. The purpose of this study was to performed a meta-analysis to compare the effect of intravenous oxycodone and fentanyl on post-operative pain in sugical patients from collected current data. Methods The RCTs of oxycodone versus fentanyl for IV-PCA were gathered from PubMed, Embase, Cochrane library, CNKI and VIP data. After data extraction and quality assessment of the included RCTs, the RevMan 5.3 software was applied for meta-analysis of numerical rating scale (NRS) scores, accumulated IV-PCA consumption of oxycodone and fentanyl, patient satisfaction, postoperative nausea and vomiting (PONV), and other adverse events (AEs). Results Results reported from eight RCTs involving 600 patients are included in the meta-analysis. The NRS score at rest and upon movement of group oxycodone was signiﬁcantly lower than that of group fentanyl (WMD= -3.85, 95% CI -4.93~-2.76, P<0.00001; WMD= -4.31, 95% CI -5.79~-2.84, P<0.00001); however, the incidence of PONV and dizziness was signiﬁcantly higher in group oxycodone than in group fentanyl (OR = 2.41, 95% CI 1.60~3.63, P < 0.0001; OR=3.69, 95% CI 2.17~6.26, P<0.00001). Accumulated IV-PCA consumption in group oxycodone was less than in group fentanyl overall the 48 hours postoperatively (WMD= -12.11, 95% CI -18.42~-5.80, P = 0.0002). There was no significant difference in patient satisfaction between oxycodone and fentanyl (OR=0.73, 95% CI 0.11~5.04, P= 0.75). Conclusion According to the evidence, this meta-analysis suggest that oxycodone IV-PCA is superior to fentanyl in postoperative pain relief, whereas the higher incidence of PONV and dizziness was accompanied with oxycodone. Further large-scale and well-designed studies are needed to summarize and analyse the data to draw a more convincing conclusion.

Clinical Relevance The use of laser light during bleaching will not reduce the incidence or severity of sensitivity and will not increase the degree of color change compared with nonlaser light sources. SUMMARY Objective: To evaluate whether the use of laser during in-office bleaching promotes a reduction in dental sensitivity after bleaching compared with other light sources. Methods: The present review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and is registered with PROSPERO (CDR42018096591). Searches were conducted in the PubMed/Medline, Web of Science, and Cochrane Library databases for relevant articles published up to August 2018. Only randomized clinical trials among adults that compared the use of laser during in-office whitening and other light sources were considered eligible. Results: After analysis of the texts retrieved during the database search, six articles met the eligibility criteria and were selected for the present review. For the outcome dental sensitivity, no significant difference was found favoring any type of light either for intensity (mean difference [MD]: −1.60; confidence interval [CI]: −3.42 to 0.22; p=0.09) or incidence (MD: 1.00; CI: 0.755 to 1.33; p=1.00). Regarding change in tooth color, no significant differences were found between the use of the laser and other light sources (MD: −2.22; CI: −6.36 to 1.93; p=0.29). Conclusions: Within the limitations of the present study, laser exerts no influence on tooth sensitivity compared with other light sources when used during in-office bleaching. The included studies demonstrated that laser use during in-office bleaching may have no influence on tooth color change.

Background: β-amyloid (Aβ) accumulates abnormally to senile plaque which is the initiator of Alzheimer's disease (AD). As one of the Aβ-degrading enzymes, Insulin-degrading enzyme (IDE) remains controversial for its protein level and activity in Alzheimer's brain. Methods: The electronic databases PubMed, EMBASE, The Cochrane Library, OVID and Sinomed were systemically searched up to Sep. 20th, 2017. And the published case-control or cohort studies were retrieved to perform the meta-analysis. Results: Seven studies for IDE protein level (AD cases = 293; controls = 126), three for mRNA level (AD cases = 138; controls = 81), and three for enzyme activity (AD cases = 123; controls = 75) were pooling together. The IDE protein level was significantly lower in AD cases than in controls (SMD = - 0.47, 95% CI [-0.69, -0.24], p < 0.001), but IDE mRNA and enzyme activity had no significant difference (SMD = 0.02, 95% CI [-0.40, 0.43] and SMD = 0.06, 95% CI [-0.41, 0.53] respectively). Subgroup analyses found that IDE protein level was decreased in both cortex and hippocampus of AD cases (SMD = -0.43, 95% CI [-0.71, -0.16], p = 0.002 and SMD = -0.53, 95% CI [-0.91, -0.15], p = 0.006 respectively). However, IDE mRNA was higher in cortex of AD cases (SMD = 0.71, 95% CI [0.14, 1.29], p = 0.01), not in hippocampus (SMD = -0.26, 95% CI [-0.58, 0.06]). Conclusions: Our results indicate that AD patients may have lower IDE protease level. Further relevant studies are still needed to verify whether IDE is one of the factors affecting Aβ abnormal accumulation and throw new insights for AD detection or therapy.

Abstract Background For patients with hepatocellular carcinoma (HCC) with microvascular invasion (MVI) after curative resection, the effects of various postoperative adjuvant therapies are not summarized in detail, and the comparison between the effects of various adjuvant therapies is still unclear. Thus, we collected existing studies on postoperative adjuvant therapies for patients with HCC with MVI after curative resection and analyzed the effects of various adjuvant therapies. Method We collected all studies on postoperative adjuvant therapy for patients with HCC with MVI after curative resection from PubMed, EMBASE, Cochrane Library and SinoMed ending on May 1, 2019. Overall survival (OS) and disease-free/recurrence-free survival (RFS) between each group were compared in these studies by calculating the pooled hazard ratio (HR) and 95% confidence interval (CI). All statistical analyses were assessed by two authors independently. Result A total of 13 studies were included in this study, including 824 postoperative adjuvant transarterial chemoembolization (pa-TACE) patients, 90 postoperative radiotherapy patients, 57 radiofrequency ablation (RFA)/re-resection patients, 16 sorafenib patients and 886 postoperative conservative treatment patients. The results showed that pa-TACE significantly improved OS and RFS compared with postoperative conservative treatment in patients with HCC with MVI after curative resection (HR: 0.64, 95% CI: 0.55–0.74, p < 0.001; HR: 0.70, 95% CI: 0.62–0.78, p < 0.001, respectively). There was no significant difference in OS between pa-TACE and radiotherapy in patients with HCC with MVI (HR: 1.75, 95% CI: 0.92–3.32, p = 0.087). RFS in patients with HCC with MVI after pa-TACE was worse than that after postoperative adjuvant radiotherapy (HR: 2.29, 95% CI: 1.43–3.65, p < 0.001). The prognosis of pa-TACE and RFA/re-resection in patients with MVI with recurrent HCC had no significant differences (HR: 0.65, 95% CI: 0.09–4.89, p = 0.671). Adjuvant treatments significantly improved the OS and RFS of patients compared with the postoperative conservative group (HR: 0.580, 95% CI: 0.480–0.710, p < 0.001; HR: 0.630, 95% CI: 0.540–0.740, p < 0.001, respectively). Conclusion Compared with postoperative conservative treatment, pa-TACE, postoperative radiotherapy and sorafenib can improve the prognosis of patients with hepatocellular carcinoma with microvascular invasion after curative resection. Postoperative radiotherapy can reduce the recurrence of patients with HCC with MVI after curative resection compared with pa-TACE.
