Abstract Background: The number of randomized controlled trials using auricular stimulation (AS) such as transauricular vagus nerve stimulation, or auricular electrostimulation or auricular acupuncture or acupressure, in experimental and clinical settings has increased markedly over the last three decades. Various clinical scores and self-reported outcomes are used as primary outcome measures to evaluate the effects of AS; they have been already analysed in an array of systematic reviews. But regarding the effect of AS on objective, physiological measures (biomarkers), for example blood values, heart rate, electrophysiological measurements and brain imaging, a systematic analysis is missing. This systematic review protocol was developed following the PRISMA guidelines to explore and evaluate for the first time the existing literature examining the impact of AS on biomarkers in randomized controlled trials as reported in their primary or secondary outcomes. Methods and analysis: The following databases will be searched: MEDLINE (PubMed), EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), ISI Web of Science, and Scopus Database. RCTs will be included if an abstract is available in English. Data collection and analysis will be conducted by two reviewers independently. Quality and risk assessment of included studies will be done using the Cochrane 6.1.0 handbook criteria and RoB 2 tool and meta-analysis of the effect of the most frequently assessed biomarkers will be conducted using the statistical software RevMan V.5.3.Ethics and dissemination: This systematic review will evaluate the effect of AS and related techniques on various blood values and physiological measures. Since all data used in this systematic review and meta-analysis will have been published, this review does not require an ethical approval. The results will be published in a peer-reviewed journal as well as presented in relevant conferences.Registration number: PROSPERO CRD42021231885

Background: Preoperative anxiety causes profound psychological and physiological reactions that may lead to a worse postoperative recovery, higher intensity of acute and persistent postsurgical pain and impaired quality of life in the postoperative period. Previous randomized controlled trials (RCTs) suggest that auricular acupuncture (AA) is safe and effective in the treatment of preoperative anxiety; however there is a lack of systematic evidence on this topic. Therefore, this protocol was developed following the PRISMA guidelines to adequately evaluate the existing literature regarding the value of AA for the reduction in anxiety in patients in a preoperative setting, compared to other forms of acupuncture, pharmacological, or no control interventions and measured with questionnaires regarding anxiety and fear. Methods: The following databases will be searched: MEDLINE (PubMed), EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), ISI Web of Science, and Scopus Database. RCTs will be included if an abstract is available in English. Data collection and analysis will be conducted by two reviewers independently. Quality and risk assessment of included studies will be done using the Cochrane 5.1.0 handbook criteria and meta-analysis of effectiveness and symptom scores will be conducted using the statistical software RevMan V.5.3. Conclusions: This systematic review will evaluate the efficacy and safety of AA for preoperative anxiety. Since all data used in this systematic review and meta-analysis have been published, this review does not require ethical approval. The results may be published in a peer-reviewed journal or be presented in relevant conferences. Registration number: PROSPERO ID CRD42020.

AbstractThis systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted to clarify the effect of melatonin supplementation on glycemic control. Databases including PubMed, MEDLINE, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials were searched until July 30th, 2018. Two reviewers independently assessed study eligibility, extracted data, and evaluated the risk of bias for included trials. Heterogeneity among included studies was assessed using Cochran’s Q test and I-square (I2) statistic. Data were pooled using random-effect models and standardized mean difference (SMD) was considered as the overall effect size. Twelve trials out of 292 selected reports were identified eligible to be included in current meta-analysis. The pooled findings indicated that melatonin supplementation significantly reduced fasting glucose (SMD=–6.34; 95% CI, –12.28, –0.40; p=0.04; I2: 65.0) and increased the quantitative insulin sensitivity check index (QUICKI) (SMD=0.01; 95% CI, 0.00, 0.02; p=0.01; I2: 0.0). However, melatonin administration did not significantly influence insulin levels (SMD=–1.03; 95% CI, –3.82, 1.77; p=0.47; I2: 0.53), homeostasis model assessment of insulin resistance (HOMA-IR) (SMD=–0.34; 95% CI, –1.25, 0.58; p=0.37; I2: 0.37) or HbA1c levels (SMD=–0.22; 95% CI, –0.47, 0.03; p=0.08; I2: 0.0). In summary, the current meta-analysis showed a promising effect of melatonin supplementation on glycemic control through reducing fasting glucose and increasing QUICKI, yet additional prospective studies are recommended, using higher supplementation doses and longer intervention period, to confirm the impact of melatonin on insulin levels, HOMA-IR and HbA1c.

207 Background: Majority of breast cancers express the estrogen receptor or progesterone receptor. CDK4/6 signaling plays a role in endocrine therapy resistance and the benefit of inhibition of these pathways has been proven in studies. Yet the impact of these agents on hematological toxicities and febrile neutropenia is a considerable safety concern. Hence, we performed a systematic review and meta-analysis of randomized controlled trials (RCT). Methods: MEDLINE, EMBASE databases and meeting abstracts from inception through June 2017 were queried. RCTs that mention anemia, thrombocytopenia, leukopenia, neutropenia and neutropenic fever as adverse effects were incorporated in the analysis. Mantel-Haenszel method was used to calculate the estimated pooled risk ratio with 95% confidence interval (CI). Random effects model was applied. Results: Five RCTs (four phase 3 and one phase 2 studies) with a total of 2671 patients were eligible for analysis. The study arm used palbociclib-letrozole, palbociclib-fulvestrant, ribociclib-letrozole and abemaciclib-fulvestrant while the control arm utilized placebo in combination with letrozole or fulvestrant. The relative risks (RR) of all-grade side effects were as follows: anemia, 3.77 (95% CI: 2.47 – 5.75, p < 0.0001); thrombocytopenia, 9.69 (95% CI: 4.26 – 22.04, p < 0.0001); leukopenia, 11.68 (95% CI: 8.19–16.65; p < 0.0001); and neutropenia, 14.09 (95% CI: 10.73–18.49; p < 0.0001). The RR of high-grade adverse effects were as follows: anemia, 2.66 (95% CI: 1.29 – 5.45, p = 0.008); thrombocytopenia, 7.08 (95% CI: 1.95 – 25.74, p = 0.003); leukopenia, 33.58 (95% CI: 14.49–77.77; p < 0.0001); and neutropenia, 40.33 (95% CI: 19.34–84.10; p < 0.001). The pooled risk of neutropenic fever was statistically significant at 4.26 (95% CI: 1.11–16.26; p = 0.034). Conclusions: CDK 4/6 inhibitors based regimen significantly contributed to all hematological toxicities as well as febrile neutropenia. These toxicities affect patients’ quality of life, add financial burden and may lead to drug dosing inconsistencies.

Background Chronic pain is a global health problem, affecting around 1 in 5 individuals in the general population. The understanding of the key role of functional brain alterations in the generation of chronic pain has led researchers to focus on pain treatments that target brain activity. Electroencephalographic neurofeedback attempts to modulate the power of maladaptive electroencephalography frequency powers to decrease chronic pain. Although several studies have provided promising evidence, the effect of electroencephalographic neurofeedback on chronic pain is uncertain. Objective This systematic review aims to synthesize the evidence from randomized controlled trials to evaluate the analgesic effect of electroencephalographic neurofeedback. In addition, we will synthesize the findings of nonrandomized studies in a narrative review. Methods We will apply the search strategy in 5 electronic databases (Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, PsycInfo, and CINAHL) for published studies and in clinical trial registries for completed unpublished studies. We will include studies that used electroencephalographic neurofeedback as an intervention for people with chronic pain. Risk-of-bias tools will be used to assess methodological quality of the included studies. We will include randomized controlled trials if they have compared electroencephalographic neurofeedback with any other intervention or placebo control. The data from randomized controlled trials will be aggregated to perform a meta-analysis for quantitative synthesis. The primary outcome measure is pain intensity assessed by self-report scales. Secondary outcome measures include depressive symptoms, anxiety symptoms, and sleep quality measured by self-reported questionnaires. We will investigate the studies for additional outcomes addressing adverse effects and resting-state electroencephalography analysis. Additionally, all types of nonrandomized studies will be included for a narrative synthesis. The intended and unintended effects of nonrandomized studies will be extracted and summarized in a descriptive table. Results Ethics approval is not required for a systematic review, as there will be no patient involvement. The search for this systematic review commenced in July 2020, and we expect to publish the findings in early 2021. Conclusions This systematic review will provide recommendations for researchers and health professionals, as well as people with chronic pain, about the evidence for the analgesic effect of electroencephalographic neurofeedback.

Background: Currently, there is no specific therapy for chronic pancreatitis (CP). The treatment of micronutrient antioxidant therapy for painful CP has been sporadically used for more than 30 years, however, its efficacy are still poorly understood. Objective: The purpose of this meta-analysis is to investigate the safety and efficacy of antioxidant therapy for pain relief in patients with CP. Setting: University Hospital in China Study Design: Systematic review and meta-analysis Methods: Two authors independently reviewed the search results and extracted data and disagreements were resolved by discussion. Effects were summarized using standardized mean differences (SMDs), weighted mean differences, or odds ratio (OR) according to the suitable effect model. MEDLINE, PsycINFO, Scopus, EMBASE, and the Cochrane Central Register of Controlled Trials were searched from 1980 through December 2012. Randomized controlled trials (RCTs) that studied antioxidant supplementation for pain relief in patients with CP were analyzed. Results: Nine randomized controlled trials (RCTs) involving 390 patients were included. Overall, there was no association of antioxidant therapy with pain reduction in CP patients (SMD, −0.55; 95% CI, −1.22 to 0.12; P = 0.67). However, antioxidant therapy significantly increased blood levels of antioxidants in CP patients versus the placebo group (SMD, 1.08; 95% CI, 0.74 to 1.43; P < 0.00001). Interestingly, combined antioxidant (selenium, β-carotene, vitamin C, vitamin E, methionine) therapy was found to be associated with pain relief (SMD, -0.93; 95% CI, -1.72 to -0.14; P = 0.02), while the trials in which a single antioxidant was used revealed no significant pain relief (SMD, -0.12; 95% CI, -1.23 to 0.99; P = 0.83) in CP patients. Strong evidence was obtained that the antioxidants increased adverse effects (OR, 6.09; 95% CI, 2.29 to 16.17, P < 0.01); nevertheless, none was serious. Limitations: Because of the small sample, a consolidated conclusion cannot be reached based on current RCTs. Large-sample RCTs are needed to clarify the analgesic effect of antioxidants in CP patients. Conclusions: Combined antioxidant therapy seems to be a safe and effective therapy for pain relief in CP patients. Measures of total antioxidant status may not help to monitor the efficacy of antioxidant therapy for patients with CP. Key words: Antioxidant, pain, chronic pancreatitis, meta-analysis
