Background: Controversy exists in the literature regarding the most optimal repair procedure for improving the adhesion between the repair resin and the existing resin composite materials. Hence the aim of the present study was to do a systematic review and to analyze the adhesion potential of resin-based composites to similar and dissimilar composites and aimed to determine the possible dominant factors affecting the bond strength results. Materials & Methods: Randomized clinical trials (RCTs) and prospective cohort design were searched through electronic databases including MEDLINE, PubMed, Web of Science, and the Cochrane Central Register of Controlled Trials for randomized clinical trials (RCTs) until July 2020 that compared different methods of composite restoration repair and a minimum mean follow-up time of 1 year. There were no restrictions on a particular treatment indication or outcome measures. Two authors independently conducted screening, risk of bias assessment, and data extraction of eligible trials in duplicate. We applied the Cochrane risk of bias assessment tool to consider the risk of bias. Results: We identified 10 articles; two of them were RCTs, and eight prospective cohort studies. There were 530 participants, with 990 teeth, dealing with resin-based composite (RBC) restorations. The intervention of defective restorations ranged from minimal intervention to total restoration replacement. The evaluation criteria were also varied with different evaluation protocols. The low number and heterogeneity of RCTs did not allow for meta-analyses. Conclusions: Although different repair protocols are mentioned in the literature according to the included studies, an appropriate and definitive conclusion can't be drawn. However, it seems repairs versus replacements should be considered as the first line of treatment when all factors lead to repair rather than replacement. Further randomized controlled trials with high methodological quality need to be conducted in order to establish evidence-based recommendations, particularly for RBC repair.

AbstractMany trials have demonstrated prime antitumor activity of novel, small molecule multikinase inhibitors (MKIs) in advanced and/or metastatic thyroid cancer (TC). In this work, the PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science, SCOPUS, and clinicaltrials.gov databases were searched. Quality/risk of bias were assessed using GRADE criteria. Randomized clinical trials (RCTs) comparing two or more systemic therapies in patients with advanced and/or metastatic thyroid cancer were assessed. A total of 1347 articles and 548 clinical trials in clinicaltrials.gov were screened. We included seven relevant RCTs comprising 1934 unique patients assigned to different MKIs. Two separate network meta-analyses included four RCTs in radioiodine refractory well-differentiated thyroid cancer (RR-WDTC) and three RCTs in medullary thyroid cancer (MTC), respectively; all with a low risk of bias. We identified three therapies for RR-WDTC: sorafenib [disease control rate (DCR) odds ratio (OR): 0.11 (95% CI: 0.03–0.40); progression-free survival (PFS) hazard ratio (HR): 1.99 (95% CI: 1.62–2.46)], vandetanib [DCR_OR:0.26 (95% CI: 0.06–1.24); PFS_HR: 0.99 (95% CI: 0.82–1.20)] and lenvatinib [DCR_OR: 0.26 (95% CI: 0.05–1.33); PFS_HR: 0.99 (95% CI: 0.81–1.22)]; and the following therapies for MTC: vandetanib 300 mg [objective response rate (ORR)_OR: 3.31 (95% CI: 0.68–16.22); vandetanib 150 mg ORR_OR: 0.60 (95% CI: 0.16–2.33)]; and cabozantinib [ORR_OR: 85.32 (95% CI: 5.22–1395.15)]. Serious side effect (SE) analysis per organ/system demonstrated a varying MKI SE profile across both RR-WDTC and MTC diagnoses, more commonly involving metabolic/nutritional disorders [OR: 2.07 [95% CI: 0.82–5.18)] and gastrointestinal SE [OR: 1.63 (95% CI: 1.0–2.66)]. This network meta-analysis on advanced and/or metastatic TC points towards a higher efficacy of lenvatinib in RR-WDTC. The included MKIs exhibit a varying SE profile across different organs/systems favoring a patient-tailored approach with the anticipated toxicities guiding clinicians’ decisions.

BackgroundEvidence suggests that pharmacists integrated into primary care can improve patient outcomes and satisfaction, but their impact on healthcare systems is unclear.AimTo identify the key impacts of pharmacists’ integration into primary care on health system indicators, such as healthcare utilisation and costs.Design and settingA systematic review of literature.MethodEmbase, MEDLINE, Scopus, the Health Management Information Consortium, CINAHL, and the Cochrane Central Register of Controlled Trials databases were examined, along with reference lists of relevant studies. Randomised controlled trials (RCTs) and observational studies published up until June 2018, which considered health system outcomes of the integration of pharmacists into primary care, were included. The Cochrane risk of bias quality assessment tool was used to assess risk of bias for RCTs; the National Institute of Health National Heart, Lung, and Blood Institute quality assessment tool was used for observational studies. Data were extracted from published reports and findings synthesised.ResultsSearches identified 3058 studies, of which 28 met the inclusion criteria. Most included studies were of fair quality. Pharmacists in primary care resulted in reduced use of GP appointments and reduced emergency department (ED) attendance, but increased overall primary care use. There was no impact on hospitalisations, but some evidence of savings in overall health system and medication costs.ConclusionIntegrating pharmacists into primary care may reduce GP workload and ED attendance. However, further higher quality studies are needed, including research to clarify the cost-effectiveness of the intervention and the long-term impact on health system outcomes.

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.

Objective--To determine if hydroxychloroquine (HCQ) reduces the incidence of new illness, hospitalization or death among outpatients at risk for or infected with SARS-CoV-2 (COVID-19). Design--Systematic review and meta-analysis of randomized clinical trials. Data sources--Search of MEDLINE, EMBASE, PubMed, medRxiv, PROSPERO, and the Cochrane Central Register of Controlled Trials. Also review of reference lists from recent meta-analyses. Study selection--Randomized clinical trials in which participants were treated with HCQ or placebo/standard-of-care for pre-exposure prophylaxis, post-exposure prophylaxis, or outpatient therapy for COVID-19. Methods--Two investigators independently extracted data on trial design and outcomes. Medication side effects and adverse reactions were also assessed. The primary outcome was COVID-19 hospitalization or death. When unavailable, new COVID-19 infection was used. We calculated random effects meta-analysis according to the method of DerSimonian and Laird. Heterogeneity between the studies was evaluated by calculation of Cochran Q and I2 parameters. An Egger funnel plot was drawn to investigate publication bias. We also calculated the fixed effects meta-analysis summary of the five studies. All calculations were done in Excel, and results were considered to be statistically significant at a two-sided threshold of P=.05. Results--Five randomized controlled clinical trials enrolling 5,577 patients were included. HCQ was associated with a 24% reduction in COVID-19 infection, hospitalization or death, P=.025 (RR, 0.76 [95% CI, 0.59 to 0.97]). No serious adverse cardiac events were reported. The most common side effects were gastrointestinal. Conclusion--Hydroxychloroquine use in outpatients reduces the incidence of the composite outcome of COVID-19 infection, hospitalization, and death. Serious adverse events were not reported and cardiac arrhythmia was rare. Systematic review registration--This review was not registered.

Background & Aims: Evaluating the effect of Kangaroo Mother Care (KMC) on breastfeeding success shows conflicting results. Regarding the importance of breastfeeding and uncertainties about its effect, this study intended to conduct a systematic review and meta-analysis of randomised controlled trials on the effect of KMC on success of breastfeeding. </P><P> Methods: In this systematic review and meta-analysis study, required data were collected by searching the following keywords: breastfeeding, Breast-Feeding, “skin-to-skin”, “Kangaroo Mother Care”, randomized clinical trial. The following databases were searched: Google Scholar, PubMed, EMBASE, Scopus, and Cochrane Central Register of Controlled Trials. Two authors independently extracted the data. To estimate the Breast-Feeding outcome variables, CMA2 software was used. The risk of bias of studies was assessed with the criteria developed in the Cochrane Handbook. Results: Twenty articles were included. In the KMC and CNC groups, 1,432 and 1,410 neonates were examined. Breastfeeding success rate was higher in the KMC group within different time slots, however this difference was not statistically significant (RR=1.11(95CI, 0.93-1.34) and RR=1.13(95%CI, 0.92-1.34) based on the time slot and birth weight, respectively). The inter-groups differences in the mean scores of Infant Breast-Feeding Assessment Tool (IBFAT) were statistically significant (P<0.05). Breastfeeding was initiated very sooner in the KMC group, suggesting a statistically significant inter-groups difference -0.72(95%CI, from -0.92 to -0.53) (P<0.05). Majority of the studies had a high risk of bias. Conclusion: Findings indicated a superiority of KMC over CNC in terms of breastfeeding success. Assessment of the complications and costs of KMC implementation is recommended.

IntroductionDamage to peripheral nerves occurs in a variety of health conditions. Preserving nerve integrity, to prevent progressive nerve damage, remains a clinical challenge. Omega-3 polyunsaturated fatty acids (PUFAs) are implicated in the development and maintenance of healthy nerves and may be beneficial for promoting peripheral nerve health. The aim of this systematic review is to assess the effects of oral omega-3 PUFA supplementation on peripheral nerve integrity, including both subjective and objective measures of peripheral nerve structure and/or function.Methods and analysisA systematic review of randomised controlled trials that have evaluated the effects of omega-3 PUFA supplementation on peripheral nerve assessments will be conducted. Comprehensive electronic database searches will be performed in Ovid MEDLINE, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL), US National Institutes of Health Clinical Trials Registry and the WHO International Clinical Trials Registry Platform. The title, abstract and keywords of identified articles will be assessed for eligibility by two reviewers. Full-text articles will be obtained for all studies judged as eligible or potentially eligible; these studies will be independently assessed by two reviewers to determine eligibility. Disagreements will be resolved by consensus. Risk of bias assessment will be performed using the Cochrane Collaboration risk of bias tool to appraise the quality of included studies. If clinically meaningful, and there are a sufficient number of eligible studies, a meta-analysis will be conducted and a summary of findings table will be provided.Ethics and disseminationThis is a systematic review that will involve the analysis of previously published data, and therefore ethics approval is not required. A manuscript reporting the results of this systematic review will be published in a peer-reviewed journal and may also be presented at relevant scientific conferences.PROSPERO registration numberCRD42018086297.

In hysterectomized patients, even though there is still controversy, evidence indicates that in the short term, the vaginal approach shows benefits over the laparoscopic approach, as it is less invasive, faster and less costly. However, the quality of sexual life has not been systematically reviewed in terms of the approach adopted. Through a systematic review, we analyzed (CRD42020158465 in PROSPERO) the impact of hysterectomy on sexual quality and whether there are differences according to the surgical procedure (abdominal or vaginal) for noncancer patients. MEDLINE (through PubMed), Embase, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov and Scopus were reviewed to find randomized clinical trials assessing sexuality in noncancer patients undergoing total hysterectomy, comparing vaginal and abdominal (laparoscopic and/or open) surgery. Three studies that assessed the issue under study were finally included. Two of these had a low risk of bias (Cochrane risk of bias tool); one was unclear. There was significant variability in how sexuality was measured, with no differences between the two approaches considered in the review. In conclusion, no evidence was found to support one procedure (abdominal or vaginal) over another for non-oncological hysterectomized patients regarding benefits in terms of sexuality.

BACKGROUND The treatment of supracondylar humerus fracture in children (SHFC) is associated with complications such as functional deficit, residual deformity, and iatrogenic neurological damage. The standard treatment is closed reduction and percutaneous Kirschner wire fixation with different configurations. Despite this fact, there is still no consensus on the most effective technique for the treatment of these fractures. OBJECTIVE The aim of this systematic review will be to evaluate the effect of surgical interventions on the treatment of Gartland type II and III SHFC by assessing function, complications, and error as primary outcomes. Clinical outcomes such as range of motion and pain and radiographic outcomes will also be judged. METHODS A systematic review of randomized controlled trials or quasi-randomized controlled trials evaluating the surgical treatment of SHFC will be carried out in the Cochrane Central Register of Controlled Trials, PubMed, Literatura Latino-Americana e do Caribe em Ciências da Saúde, and Excerpta Medica Database. The search will also occur at ongoing and recently completed clinical trials in selected databases. Data management and extraction will be performed using a data withdrawal form and by analyzing the following: study method characteristics, participant characteristics, intervention characteristics, results, methodological domains, and risk of bias. To assess the risk of bias of the included trials, the Cochrane Risk of Bias Tool will be used. Dichotomous outcome data will be analyzed as risk ratios, and continuous outcome data will be expressed as mean differences, both with 95% confidence intervals. Also, whenever possible, subgroup analysis, sensitivity analysis, and assessment of heterogeneity will be performed. RESULTS Following the publication of this protocol, searches will be run and included studies will be deeply analyzed. We hope to obtain final results in the next few months and have the final paper published by the end of 2018. This study was funded by a government-based noncommercial agency, Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP). CONCLUSIONS This study may provide surgical treatment effects evidence for SHFC. The results will assist clinical practice by demonstrating the effectiveness and potential complications of these interventions and might serve as a reference for future clinical trials on the topic.

Objectives: This systematic review of the literature was carried out to see whether coffee consumption could affect Parkinson’s disease (PD) symptoms. Methods: Randomized controlled trials (RCTs), crossover studies, and quasi-experimental studies were assessed to evaluate the effect of caffeine on PD. The databases including Medline/PubMed, ProQuest, Embase, Cochrane Library, and ClinicalTrials.gov were systematically searched. The Cochrane Collaboration’s tool for assessing the risk of bias in randomized clinical trials and the Cochrane risk of bias assessment tool for non-randomized studies of interventions (ROBINS-I) were used to assess the quality of RCTs and non-randomized clinical trials, respectively. A meta-analysis of the results was not possible because of reporting different outcomes. Results: Four papers were included in this study. Only one study reported the significant effect of caffeine on ESS and UPDRS. Another study observed no significant effect of caffeine on ESS during three- and six-week interventions. However, a significant reduction in ESS scores in the sixth week was reported after excluding four protocol violations. This study reported that the UPDRS score reduced in the third week, but significant changes were observed after six weeks. The other two studies did not show a significant effect of caffeine on ESS and UPDRS. Conclusions: Since a meta-analysis was not conducted, there was insufficient evidence to evaluate the effect of caffeine on PD. Thus, it is recommended to conduct more well-designed RCTs with a larger sample size to assess the effect of caffeine on PD.

A broad spectrum of novel targeted therapies with prime antitumor activity and/or ample control of hormonal symptoms together with an overall acceptable safety profile have emerged for patients with metastatic neuroendocrine neoplasms (NENs). In this systematic review and quantitative meta-analysis, the PubMed, EMBASE, Cochrane Central Register of Controlled Trials and clinicaltrials.gov databases were searched to assess and compare the safety profile of NEN treatments with special focus on the cardiovascular adverse effects of biotherapy and molecular targeted therapies (MTTs). Quality/risk of bias were assessed using GRADE criteria. Placebo-controlled randomized clinical trials (RCTs) in patients with metastatic NENs, including medullary thyroid cancer (MTC) were included. A total of 3695 articles and 122 clinical trials registered in clinicaltrials.gov were screened. We included sixteen relevant RCTs comprising 3408 unique patients assigned to different treatments compared with placebo. All the included studies had a low risk of bias. We identified four drug therapies for NENs with eligible placebo-controlled RCTs: somatostatin analogs (SSAs), tryptophan hydroxylase (TPH) inhibitors, mTOR inhibitors and tyrosine kinase inhibitors (TKI). Grade 3 and 4 adverse effects (AE) were more often encountered in patients treated with mTOR inhibitors and TKI (odds ratio [OR]: 2.42, 95% CI: 1.87–3.12 and OR: 3.41, 95% CI: 1.46–7.96, respectively) as compared to SSAs (OR:0.77, 95% CI: 0.47–1.27) and TPH inhibitors (OR:0.77, 95% CI: 0.35–1.69). MTOR inhibitors had the highest risk for serious cardiac AE (OR:3.28, 95% CI: 1.66–6.48) followed by TKIs (OR:1.51, 95% CI: 0.59–3.83). Serious vascular AE were more often encountered in NEN patients treated with mTOR inhibitors (OR: 1.72, 95% CI: 0.64–4.64) and TKIs (OR:1.64, 95% CI: 0.35–7.78). Finally, patients on TKIs were at higher risk for new-onset or exacerbation of pre-existing hypertension (OR:3.31, 95% CI: 1.87–5.86). In conclusion, SSAs and TPH inhibitors appear to be safer as compared to mTOR inhibitors and TKIs with regards to their overall toxicity profile, and cardiovascular toxicities in particular. Special consideration should be given to a patient-tailored approach with anticipated toxicities of targeted NEN treatments together with assessment of cardiovascular comorbidities, assisting clinicians in treatment selection and early recognition/management of cardiovascular toxicities. This approach could improve patient compliance and preserve cardiovascular health and overall quality of life.
