ABSTRACTBackground: In randomized clinical trials, adverse events (AEs) are reported for the drug under evaluation and compared with the placebo group. Patients who receive placebo treatment report a high frequency of AEs, but little is understood about the nature of these. No study has yet analyzed the level of cognitive impairment as a crucial aspect for the AEs reported by patients.Methods: The rates of AEs reported by patients with mild cognitive impairment (MCI) and Alzheimer's disease (AD) in the placebo arms of donepezil trials were compared using a systematic review approach. PubMed was searched with the terms “MCI and donepezil” as well as “AD and donepezil” from January 1989 to December 2010. Nineteen studies fulfilled the selection criteria (3 MCI, n = 783; 16 AD, n = 2,059).Results: An overall comparison of 81 categories of AEs in the placebo arm of MCI versus AD trials showed that patients in AD trials experienced a significantly higher number of AEs than patients in MCI trials (p < 0.001).Conclusions: This is the first study showing that AD patients may be at a greater risk of developing AEs than MCI patients. This may be related to a greater presence of somatic comorbidity predisposing them to express emotional distress as physical symptoms and/or to AD patients being frailer and therefore more susceptible to AEs. The phenomena we observed may be interpreted in terms of the “nocebo effect”.

Background and Objectives: Oral cancer is the 6th most common cancer in the world and oral leukoplakia is an oral potentially malignant disorder that could develop into oral cancer. This systematic review focusses on randomized clinical trials for recombinant adenovirus p-53 (rAD-p53) therapy for the treatment of oral leukoplakia and cancer. Materials and Methods: We searched for research articles on various databases such as Pubmed/Medline, Embase, CNKI (China National Knowledge Infra-structure), Springerlink, cochrane and Web of sciences from 2003 to 2020. MeSH (Medical Subject Headings) terms were used for the search. Inclusion criteria included original research, randomized clinical trials and articles only in English language. Exclusion criteria were any articles that were not research articles, not randomized trials, non-human studies, etc. The articles were further graded on the Jadad scale. Results: 578 articles were assessed from various databases; only 3 articles were found to be appropriate for this review. Thus, meta-analysis was not performed because of heterogeneity and lack of data. In the three studies, whether rAD-p53 was used as a standalone therapy or with other therapies, there was a beneficial effect of the therapy. Furthermore, there were no serious adverse events and the only adverse events reported were fever, pain at the local injection site, flu-like symptoms and lowered WBC count. Conclusions: Thus, we can conclude that this therapy has a potential for beneficial therapeutic effects and further clinical trials with more patients need to be performed to get better understanding of the effect of rAD-p53 therapy, which probably will pave the way to its approval in other parts of the world.

Abstract Background Biochemical markers of bone turnover (BTMs), such as the bone alkaline phosphatase (bALP), procollagen type I N propeptide (PINP), serum cross-linked C-telopeptides of type I collagen (bCTx), and urinary cross-linked N-telopeptides of type I collagen (NTx), are used to manage therapy monitoring in osteoporotic patients. This systematic review analyzed the potential of these BMTs in predicting the clinical outcomes in terms of BMD, t-score, rate of fractures, and adverse events during the therapy setting in postmenopausal osteoporosis. Methods All randomized clinical trials (RCTs) reporting data on biomarkers for postmenopausal osteoporosis were accessed. Only articles reporting quantitative data on the level of biomarkers at baseline and on the outcomes of interest at the last follow-up were eligible. Results A total of 36,706 patients were retrieved. Greater values of bALP were associated with a greater rate of vertebral (P = 0.001) and non-vertebral fractures (P = 0.0001). Greater values of NTx at baseline were associated with a greater rate of adverse events at the last follow-up (P = 0.02). Greater values of CTx at baseline were associated with a greater rate of adverse events leading to discontinuation (P = 0.04), gastrointestinal adverse events (P = 0.0001), musculoskeletal adverse events (P = 0.04), and mortality (P = 0.04). Greater values of PINP at baseline were associated with greater rates of gastrointestinal adverse events (P = 0.02) at the last follow-up. Conclusion The present analysis supports the adoption of BMTs during pharmacological therapy setting of patients suffering from osteoporosis. Level of evidence I, systematic review of RCTs

Abstract Background Carpal tunnel syndrome (CTS) is a common upper limb entrapment neuropathy; severe cases are treated surgically and mild to moderate can be managed conservatively. The purpose of this systematic review and meta-analysis was to define the efficacy of gabapentin as an adjuvant to splinting in the treatment of mild to moderate CTS. Methods A systematic search through 13 databases, randomized clinical trials (RCTs) reporting the use of gabapentin with splinting in CTS were included and analyzed. Results Three RCTs including 170 patients were eligible. There was no significant difference between gabapentin plus splinting and splinting alone in 5 measured parameters: (1) Symptom Severity Scale (SSS) [MD (95% CI) = − 0.76 (− 2.46–0.93), p = 0.378], (2) Functional Status Scale (FSS) [MD (95% CI) = − 0.23 (− 1.40–0.94), p = 0.701], (3) visual analogue scale (VAS) to assess pain [MD (95% CI) = − 0.6 (− 1.47–0.27), p = 0.174], (4) Grip strength [MD (95% CI) = − 0.11 (− 0.70–0.48), p = 0.718], and (5) pinch strength [MD (95% CI) = 0.72 (− 0.10–1.54), p = 0.083]. Conclusion This review provides low-quality evidence that gabapentin plus nocturnal splinting is not superior to splinting alone. More high-quality trials are needed to determine the role of this drug as an adjuvant in the management of CTS.

Abstract   Gastroesophageal reflux disease (GERD) is a widely studied and highly prevalent condition. However, few is reported about the exact efficacy and safety of fundoplication (FPT) compared to oral intake proton-pump inhibitors (PPI). This systematic review and meta-analysis of randomized clinical trials (RCT) aims to compare PPI and FPT in relation to the efficacy, as well as the adverse events associated with these therapies. Methods This systematic review was guided by PRISMA statement. Search carried out in June 2020 was conducted on Medline, Cochrane, EMBASE and LILACS. The inclusion criteria were (I) patients with GERD; (II) Randomized clinical trials, comparing oral intake PPI with FPT; (III) relevant outcomes for this review. The exclusion criteria were (I) reviews, case reports, editorials and letters (II) transoral or endoscopic FPT (III) studies with no full text. No restrictions were set for language or period. Certainty of evidence and risk of bias were assessed with GRADE Pro and with Review Manager Version 5.4 bias assessment tool. Results Ten RCT were included. Meta-analysis showed that heartburn (RD = −0.19; 95% CI = −0.29, −0.09) was less frequently reported by patients that underwent FPT. Furthermore, patients undergoing surgery had greater pressure on the lower esophageal sphincter than those who used PPI (MD = 7.81; 95% CI 4.79, 10.83). There was no significant difference between groups in the percentage of time with pH less than 4 in 24 hours, sustained remission and Gastrointestinal Symptom Rating Scale. Finally, FPT did not increase significantly the risk for adverse events such as postoperative dysphagia and impaired belching. Conclusion FPT is a more effective therapy than PPI treatment for GERD, without significantly increasing the risk for adverse events. However, before indicating a possible surgical approach, it is extremely important to correctly assess and select the patients who would benefit from FPT, such as those with severe erosive esophagitis, severe respiratory symptoms, low adherence to continuous drug treatment and patients with non-acid reflux, to ensure better results.

Objectives: To evaluate the efficacy, speed of onset, and adverse events of 6 mg subcutaneous, 100 mg oral, and 20 mg intranasal sumatriptan in the treatment of migraine attacks. Design: Systematic review of placebo-controlled randomized clinical trials. Data sources: Thirty trials up to April 1997 retrieved from a systematic literature search (Medline, review papers, handsearching of journals, congress proceedings, manufacturer's database); no restriction on language. Outcome parameters: Numbers needed to treat (NNT) were calculated for relief of headache and for adverse events (when data were available). Therapeutic gain was used to evaluate speed of onset of action. Results: Subcutaneous sumatriptan was more efficacious, combined number needed to treat 2.0 at 1 h, than oral (3.0 at 2 h) and intranasal sumatriptan (3.1 at 2 h). For adverse events, the NNT was 3.0 for subcutaneous and 8.3 for oral sumatriptan. Only limited data on adverse events for intranasal sumatriptan were available. Therapeutic gain analysis during the first 2 h showed that subcutaneous sumatriptan was the fastest-acting form of administration. Conclusions: Subcutaneous sumatriptan in a dose of 6 mg is significantly more efficacious than 100 mg of oral sumatriptan, but causes more adverse events than oral sumatriptan. Subcutaneous sumatriptan is the form with the quickest onset of action. Intranasal sumatriptan has the same efficacy as oral sumatriptan and a quicker onset of action than the oral form, but with a limited therapeutic effect for the first 30 min after administration.

Abstract Background: Many studies have evaluated the role of polyvalent immunoglobulins (IVIG) and CMV-hyperimmune IVIG (CMV-IVIG) prophylaxis in patients undergoing hematopoietic stem cell transplantation (HSCT), with inconsistent results and implications for practice. Objectives: To evaluate the role of IVIG and CMV- IVIG prophylaxis in HSCT. Methods: Systematic review and meta-analysis of randomized controlled trials comparing IVIG or CMV- IVIG with placebo or no intervention (control) for prophylaxis in HSCT. The Cochrane Library, MEDLINE, conference proceedings and references were searched until 2007. Primary outcome: all-cause-mortality ; Secondary outcomes: CMV infections, acute graft versus host disease (GVHD), interstitial pneumonitis (IP), veno-occlusive disease (VOD) and adverse events. Relative risks (RR) with 95% confidence intervals (CIs) were estimated and pooled. Results: Nineteen trials met inclusion criteria. IVIG was compared to control in 10 trials (7 IVIG in allogeneic HSCT, 2 allogeneic/autologous HSCT and 1 autologous HSCT). When IVIG was compared to control, there was no difference in all-cause mortality (RR 1.03; 95% CI 0.89–1.18, 6 trials, Fig.). There was a reduction in the number of CMV infections (RR 0.70; 95% CI 0.50–0.99, 4 trials) and in the number of episodes of IP (RR 0.61; 95% CI 0.43–0.87, 6 trials). There was no significant difference in the number of episodes of acute GVHD (RR 0.93; 95% CI 0.83–1.05, 6 trials). The risk for VOD was increased (RR 2.71; 95% CI 1.06–6.94, 3 trials) as were adverse events in the IVIG group (RR 8.12; 95% CI 3.15–20.9, 5 trials). CMV-IVIG was compared to control in 7 trials, all allogeneic HSCT. There was no difference in all-cause mortality (RR 0.86; 95% CI 0.63–1.16, 4 trials). In addition, there were no differences in the risk for developing CMV infections (RR 1.07; 95% CI 0.86–1.33, 7 trials), acute GVHD (RR 1.02; 95% CI 0.72–1.44, 5 trials) or IP (0.95; 95% CI 0.58–1.56, 5 trials). Conclusions: Our review demonstrates that IVIG prophylaxis for HSCT reduces the risk for CMV infections and IP without a significant influence on mortality. The beneficial effects should be weighed against the higher incidence of adverse events, VOD, and cost associated with the use of prophylactic IVIG in HSCT patients. Conversely, the use of CMV-IVIG was not associated with a change in any of the parameters. Outcomes Summary Outcome IVIG vs. control CMV-IVIG vs. control All Cause Mortality RR 1.03; 95% CI 0.89–1.18 RR 0.86; 95% CI 0.63–1.16 CMV infections RR 0.70; 95% CI 0.50–0.99 RR 1.07; 95% CI 0.86–1.33 acute GVHD RR 0.93; 95% CI 0.83–1.05 RR 1.02; 95% CI 0.72–1.44 IP RR 0.61; 95% CI 0.43–0.87 RR 0.95; 95% CI 0.58–1.56 VOD RR 2.71; 95% CI 1.06–6.94 No data Adverse events RR 8.12; 95% CI 3.15–20.9 RR 7.0; 95% CI 0.38–129.34 Figure Figure

The evidence of acupressure is limited in the management of dysmenorrhea. To evaluate the efficacy of acupressure in the treatment of primary dysmenorrhea based on randomized controlled trials (RCTs), we searched MEDLINE, the Chinese Biomedical Database (CBM), and the Cochrane Central Register of Controlled Trials (CENTRAL) databases from inception until March 2012. Two reviewers independently selected articles and extracted data. Statistical analysis was performed with RevMan 5.1 software. Eight RCTs were identified from the retrieved 224 relevant records. Acupressure improved pain measured with VAS (−1.41 cm 95% CI [−1.61, −1.21]), SF-MPQ at the 3-month followup (WMD −2.33, 95% CI [−4.11, −0.54]) and 6-month followup (WMD −4.67, 95% CI [−7.30, −2.04]), and MDQ at the 3-month followup (WMD −2.31, 95% CI [−3.74, −0.87]) and 6-month followup (WMD −4.67, 95% CI [−7.30, −2.04]). All trials did not report adverse events. These results were limited by the methodological flaws of trials.

ABSTRACT Objective: To determine whether long-acting muscarinic antagonists (LAMAs) provide superior therapeutic effects over long-acting β2 agonists (LABAs) for preventing COPD exacerbations. Methods: This was a systematic review and meta-analysis of randomized clinical trials involving patients with stable, moderate to severe COPD according to the Global Initiative for Chronic Obstructive Lung Disease criteria, treated with a LAMA (i.e., tiotropium bromide, aclidinium, or glycopyrronium), followed for at least 12 weeks and compared with controls using a LABA in isolation or in combination with a corticosteroid. Results: A total of 2,622 studies were analyzed for possible inclusion on the basis of their title and abstract; 9 studies (17,120 participants) were included in the analysis. In comparison with LABAs, LAMAs led to a greater decrease in the exacerbation rate ratio (relative risk [RR] = 0.88; 95% CI: 0.84-0.93]; a lower proportion of patients who experienced at least one exacerbation (RR = 0.90; 95% CI: 0.87-0.94; p < 0.00001); a lower risk of exacerbation-related hospitalizations (RR = 0.78; 95% CI: 0.69-0.87; p < 0.0001); and a lower number of serious adverse events (RR = 0.81; 95% CI: 0.67-0.96; p = 0.0002). The overall quality of evidence was moderate for all outcomes. Conclusions: The major findings of this systematic review and meta-analysis were that LAMAs significantly reduced the exacerbation rate (exacerbation episodes/year), as well as the number of exacerbation episodes, of hospitalizations, and of serious adverse events.
