ABSTRACTObjectivesEvaluate the relationship between naloxone dose (initial and cumulative) and opioid toxicity reversal and adverse events in undifferentiated and presumed fentanyl/ultra-potent opioid overdoses.MethodsWe searched Embase, MEDLINE, Cochrane Central Register of Controlled Trials, DARE, CINAHL, Science Citation Index, reference lists, toxicology websites, and conference proceedings (1972 to 2018). We included interventional, observational, and case studies/series reporting on naloxone dose and opioid toxicity reversal or adverse events in people >12 years old.ResultsA total of 174 studies (110 case reports/series, 57 observational, 7 interventional) with 26,660 subjects (median age 35 years; 74% male). Heterogeneity precluded meta-analysis. Where reported, we abstracted naloxone dose and proportion of patients with toxicity reversal. Among patients with presumed exposure to fentanyl/ultra-potent opioids, 56.9% (617/1,085) responded to an initial naloxone dose ≤0.4 mg compared with 80.2% (170/212) of heroin users, and 30.4% (7/23) responded to an initial naloxone dose >0.4 mg compared with 59.1% (1,434/2,428) of heroin users. Among patients who responded, median cumulative naloxone doses were higher for presumed fentanyl/ultra-potent opioids than heroin overdoses in North America, both before 2015 (fentanyl/ultra-potent opioids: 1.8 mg [interquartile interval {IQI}, 1.0, 4.0]; heroin: 0.8 mg [IQI, 0.4, 0.8]) and after 2015 (fentanyl/ultra-potent opioids: 3.4 mg [IQI, 3.0, 4.1]); heroin: 2 mg [IQI, 1.4, 2.0]). Where adverse events were reported, 11% (490/4,414) of subjects experienced withdrawal. Variable reporting, heterogeneity and poor-quality studies limit conclusions.ConclusionsPractitioners have used higher initial doses, and in some cases higher cumulative naloxone doses to reverse toxicity due to presumed fentanyl/ultra-potent opioid exposure compared with other opioids. High-quality comparative naloxone dosing studies assessing effectiveness and safety are needed.

We performed a systematic review with the objective of verifying the efficacy of topical use 5% Acyclovir-1% Hydrocortisone cream compared to the placebo group for herpes simplex labialis treatment. We performed a literature search using MEDLINE, Embase, BIOSIS, LILACS, Scopus, Grey literature, the Cochrane Central Register of Controlled Trials, the ISI Web of Science and IBECS from 1990 to June 2014. We reported the outcomes using relative risk (RR) with 95% confidence intervals. The literature search yielded 180 potentially relevant publications. Reviews of the reference lists yielded two further citations. Among these papers, two were considered eligible for inclusion in this review. Both trials included 1,213 patients. A meta-analysis of these studies showed a RR = 0.77, (95% CI 0.70-0.86; p<0.001).This result suggests that an early episodic treatment with the combination of an antiviral and a steroid is beneficial for herpes simplex labialis treatment.

PurposeSleep duration is thought to play a key role in the development of metabolic syndrome. However, the results have been inconsistent.MethodsWe conducted a systematic review and meta-analysis of cohort studies and searched publications in PubMed, Embase, Cochrane Central Register of Controlled Trials, and Clinicaltrials.gov. The summary relative risks (RRs) were estimated using a random model. The sensitivity analysis was performed by sequentially excluding each study to test the robustness of the pooled estimates.FindingWe included 13 studies involving 300,202 patients in which short sleep and long sleep significantly increased the risk of metabolic syndrome 15% (RR = 1.15, 95%CI = 1.09-1.22, p &lt; 0.001) and 19% (RR = 1.19, 95%CI = 1.05-1.35, p &lt; 0.001). Moreover, the relationship between sleep duration and metabolic syndrome risk presented a U-shaped curve. Short and long sleep increased the risk of obesity by 14% (RR = 1.14, 95%CI = 1.07-1.22, p&lt;0.001) and 15% (RR = 1.15, 95%CI = 1.00-1.30, p = 0.04), and high blood pressure 16% (RR = 1.16, 95%CI = 1.02-1.31, p = 0.03) and 13% (RR = 1.13, 95%CI = 1.04-1.24, p = 0.01), respectively. Short sleep can potentially increase the risk of high blood sugar by 12% (RR = 1.12, 95%CI = 1.00-1.15, P = 0.05).ImplicationsBased on our findings, sleep is a behavior that can be changed and is economical. Clinically doctors and health professionals should be encouraged to increase their efforts to promote healthy sleep for all people.

Background: Roxadustat is a new oral drug for anemia in chronic kidney disease (CKD). This study aimed to synthesize the evidence from randomized controlled trial (RCT)-based studies that estimated the efficacy and safety of roxadustat in anemia patients with non-dialysis-dependent (NDD) and dialysis-dependent (DD) CKD.Methods: We searched the PubMed, Web of Science, and Cochrane Central Register of Controlled Trials (CENTRAL) databases for related published studies. Moreover, we manually searched relevant pharmaceutical company websites and two international clinical trial registers to search for published and unpublished RCTs comparing roxadustat with erythropoietin-stimulating agents (ESAs) or placebo.Results: Fifteen RCTs (seven for DD-CKD patients, eight for NDD-CKD patients) were included in the meta-analysis, with 10,189 patients, 4,810 DD-CKD patients, and 5,379 NDD-CKD patients enrolled. Compared with ESAs (epoetin alfa or darbepoetin alfa) and placebo, roxadustat raised the hemoglobin level [weighted mean difference (WMD): 0.82 g/dL; 95% confidence interval (CI): 0.43–1.21], transferrin level (WMD: 0.5 g/L; 95% CI: 0.34–0.65), and TIBC level (WMD: 41.79 μg/dL; 95% CI: 38.67–44.92) and lowered the hepcidin level (WMD: −37.38 ng/ml; 95% CI: −46.63– −28.12) in both the DD-CKD and NDD-CKD patients with renal anemia. Roxadustat improved hemoglobin response and lowered the ferritin and TAST levels in the NDD-CKD patients but not in the DD-CKD patients. Furthermore, there was no difference between the treatment-emergent adverse events (TEAEs) of roxadustat and that of ESAs or placebo. But the incidence of serious TEAEs in the roxadustat group was significantly higher with NDD-CKD patients (OR: 1.15; 95% CI: 1.02–1.29).Conclusion: This study confirmed that roxadustat therapy could alleviate the anemia of DD-CKD and NDD-CKD patients by raising the hemoglobin level and regulating iron metabolism, but increased serious incidences of treatment-emergent adverse events (TEAEs) in NDD-CKD patients.

Background: Since the introduction of glucocorticoids (GCs) in the physician’s pharmacological arsenal, it has been known that they are a cause of behavioral or psychiatric adverse events (BPAE), as well as of cognitive problems. To the best of our knowledge, the relationship between these adverse events and GCs in older persons has never been evaluated, except through case-reports or series with few cases. In this paper, a review of the literature regarding BPAEs and cognitive disorders in older people treated with CSs is undertaken. Methods: A comprehensive literature search for BPAEs was carried out on the three main bibliographic databases: EMBASE, MEDLINE and PsycINFO (NICE HDAS interface). Emtree terms were: Steroid, steroid therapy, mental disease, mania, delirium, agitation, depression, behavior change, dementia, major cognitive impairment, elderly. The search was restricted to all clinical studies and case reports with focus on the aged (65+ years) published in any language since 1998. Results: Data on the prevalence of the various BPAEs in older patients treated with GCs were very scarse, consisting mainly of case reports and of series with small numbers of patients. It was hence not possible to perform any statistical evaluation of the data (including meta-analysis). Amongst BPAEs, he possibility that delirium can be induced by GCs has been recently been questioned. Co-morbidities and polypharmacy were additional risk factors for BPAEs in older persons. Conclusions: Data on BPAEs in older persons treated with GCs, have several unmet needs that need to be further evaluated with appropriately designed studies.

92 Background: Immunotherapy (IO) can lead to immune-related adverse events (irAEs). Evidence on the association of irAEs and efficacy is limited. Methods: We conducted a systematic review in MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials (inception to July 1, 2019) to identify randomized controlled trials (RCTs) reporting irAEs, incidence and efficacy data for pembrolizumab (PEM), nivolumab (NIVO), ipilimumab (IPI), atezolizumab, avelumab, durvalumab, and aldesleukin in lung, renal, head and neck cancer, and melanomas. RCTs assessing IO monotherapy or IO combinations in at least one arm were included. Evaluated outcomes were 1) irAE incidence (rash, pruritis, diarrhea, colitis, hypothyroidism, hyperthyroidism, transaminitis, hypophysitis, pneumonitis, arthralgia, anemia, and hepatitis); and 2) efficacy (response and survival). irAE incidence data will be pooled and meta-analysis performed to assess the association of irAEs with efficacy; heterogeneity between RCTs will be evaluated. Results: Fifty RCTs were included: IOs were compared to chemotherapy or chemotherapy-combinations (19), to other interventions (8), to placebo (3), and head-to-head (20). irAE reporting and definitions were heterogeneous across RCTs. The most common all-grade irAEs were skin, GI, and endocrine. For skin irAEs, rash ranged from 0% (PEM 2 mg/kg, n = 6) to 73% (NIVO + IPI, n = 11); pruritus was from 1% (PEM 2 mg/kg, n = 89) to 50% (NIVO + IPI, n = 6). For GI irAEs, diarrhea ranged from 0% (PEM 2 mg/kg, n = 6) to 64% (NIVO + IPI, n = 11); colitis was from 0% (NIVO 3 mg/kg, n = 98) to 23% (NIVO + IPI, n = 94). For endocrine irAEs, hypothyroidism ranged from 0% (NIVO 3 mg/kg, n = 12) to 83% (NIVO + IPI, n = 6), hyperthyroidism was from 0% (PEM 2 mg/kg, n = 6 and IPI 3 mg/kg, n = 46) to 27% (NIVO + IPI, n = 11), and hypophysitis was from 0% (PEM 10 mg/kg, n = 84 and NIVO 3 mg/kg, n = 25) to 26% (NIVO + IPI, n = 35). Liver, pulmonary, and musculoskeletal irAEs, and anemia, were reported less frequently and with lower incidence. Conclusions: irAEs are increasingly reported in IO RCTs, but lack reporting and definition consistency. The meta-analysis results may provide clarity on irAEs incidence and association with efficacy.

Chemotherapy is widely used in the treatment of cancer patients, but the cardiotoxicity induced by chemotherapy is still a major concern to most clinicians. Currently, genetic methods have been used to detect patients with high risk of chemotherapy-induced cardiotoxicity (CIC), and our study evaluated the correlation between genomic variants and CIC. The systematic literature search was performed in the PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), China Biology Medicine disc (CBMdisc), the Embase database, China National Knowledge Internet (CNKI) and Wanfang database from inception until June 2020. Forty-one studies were identified that examined the relationship between genetic variations and CIC. And these studies examined 88 different genes and 154 single nucleotide polymorphisms (SNPs). Our study indicated 6 variants obviously associated with the increased risk for CIC, including CYBA rs4673 (pooled odds ratio, 1.93; 95% CI, 1.13–3.30), RAC2 rs13058338 (2.05; 1.11–3.78), CYP3A5 rs776746 (2.15; 1.00–4.62) ABCC1 rs45511401 (1.46; 1.05–2.01), ABCC2 rs8187710 (2.19; 1.38–3.48), and HER2-Ile655Val rs1136201 (2.48; 1.53–4.02). Although further studies are required to validate the diagnostic and prognostic roles of these 6 variants in predicting CIC, our study emphasizes the promising benefits of pharmacogenomic screening before chemotherapy to minimize the CIC.

Clinical trials evaluating the safety and antibody response of strategies to manipulate prophylactic and therapeutic immunity have been launched. We aim to evaluate strategies for augmentation of host immunity against severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. We searched clinical trials registered at the National Institutes of Health by 25 May 2021 and conducted analyses on inoculated populations, involved immunological processes, source of injected components, and trial phases. We then searched PubMed, Embase, Scopus, and the Cochrane Central Register of Controlled Trials for their corresponding reports published by 25 May 2021. A bivariate, random-effects meta-analysis was used to derive the pooled estimate of seroconversion and adverse events (AEs). A total of 929,359 participants were enrolled in 389 identified trials. The working mechanisms included heterologous immunity, active immunity, passive immunity, and immunotherapy, with 62.4% of the trials on vaccines. A total of 9072 healthy adults from 27 publications for 22 clinical trials on active immunity implementing vaccination were included for meta-analyses. The pooled odds ratios (ORs) of seroconversion were 13.94, 84.86, 106.03, and 451.04 (all p < 0.01) for vaccines based on protein, RNA, viral vector, and inactivated virus, compared with that of respective placebo/control treatment or pre-vaccination sera. The pooled ORs for safety, as defined by the inverse of systemic adverse events (AEs) were 0.53 (95% CI = 0.27–1.05; p = 0.07), 0.35 (95% CI = 0.16–0.75; p = 0.007), 0.32 (95% CI = 0.19–0.55; p < 0.0001), and 1.00 (95% CI = 0.73–1.36; p = 0.98) for vaccines based on protein, RNA, viral vector, and inactivated virus, compared with that of placebo/control treatment. A paradigm shift from all four immune-augmentative interventions to active immunity implementing vaccination was observed through clinical trials. The efficacy of immune responses to neutralize SARS-CoV-2 for these vaccines was promising, although systemic AEs were still evident for RNA-based and viral vector-based vaccines.

AbstractBACKGROUNDRemdesivir, an inhibitor of viral RNA-dependent RNA polymerases, has been identified as a candidate for COVID-19 treatment. However, the therapeutic effect of remdesivir is controversial.METHODSWe searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials, from inception to June 11, 2020 for randomized controlled trials on the clinical efficacy of remdesivir. The main outcomes were discharge rate, mortality, and adverse events. This study is registered at INPLASY (INPLASY202060046).RESULTSData of 1075 subjects showed that remdesivir significantly increased the discharge rate of patients with COVID-19 compared with the placebo (50.4% vs. 45.29%; relative risk [RR] 1.19 [95% confidence interval [CI], 1.05–1.34], I2 = 0.0%, P = 0.754). It also significantly decreased mortality (8.18% vs. 12.70%; RR 0.64 [95% CI, 0.44–0.92], I2 = 45.7%, P = 0.175) compared to the placebo. Data of 1296 subjects showed that remdesivir significantly decreased the occurrence of serious adverse events (RR 0.77 [95% CI, 0.63–0.94], I2 = 0.0%, P = 0.716).CONCLUSIONRemdesivir is efficacious and safe for the treatment of COVID-19.TRIAL REGISTRATION NUMBERThis study is registered at the International Platform of Registered Systematic Review and Meta-analysis Protocols (INPLASY202060046).

Abstract Background There are several known factors influencing the efficacy and tolerability of biological therapies. Whether patient sex affects this is currently unclear, yet this knowledge would be helpful for risk and benefit stratification. This study assesses the role of patient sex on the efficacy and tolerability of biological therapies used for the treatment of IBD. Methods A systematic literature search was performed on 08 April 2019 using Embase (including Medline), Medline OvidSP, Cochrane Central Register of Controlled Trials, Web of Science and Pubmed. The primary outcome was the influence of patient sex on endoscopic outcomes in IBD patients treated with biologicals. The secondary outcome was the influence of patient sex on adverse events during biological therapy. Studies examining either of the outcomes were included in the assessment, regardless of study type or setting. Results The search yielded 19461 citations. After review 55 studies were included in the study, involving 28465 patients treated with adalimumab, certolizumab pegol, infliximab or vedolizumab. Of the 41 studies that objectively examined patient sex and efficacy of biological therapy, none found a significant association. Of the 14 studies examining patient sex and adverse events, 7 found that adverse events such as infections or skin lesions occur more frequently in female than in male patients. No meta-analysis of the primary or secondary outcome could be performed due to lack of exact reporting of summary measures. Conclusion There is no evidence for a sex difference in endoscopically measured response to biological therapies in IBD patients. However, there is a possible influence of sex on the occurrence of adverse events with a higher incidence in females.

Objective Although there is a growing interest in the use of acupuncture during pregnancy, the safety of acupuncture is yet to be rigorously investigated. The objective of this review is to identify adverse events (AEs) associated with acupuncture treatment during pregnancy. Methods We searched Medline, Embase, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Allied and Complementary Medicine Database (AMED) and five Korean databases up to February 2013. Reference lists of relevant articles were screened for additional reports. Studies were included regardless of their design if they reported original data and involved acupuncture needling and/or moxibustion treatment for any conditions in pregnant women. Studies of acupuncture for delivery, abortion, assisted reproduction or postpartum conditions were excluded. AE data were extracted and assessed in terms of severity and causality, and incidence was determined. Results Of 105 included studies, detailed AEs were reported only in 25 studies represented by 27 articles (25.7%). AEs evaluated as certain, probable or possible in the causality assessment were all mild/moderate in severity, with needling pain being the most frequent. Severe AEs or deaths were few and all considered unlikely to have been caused by acupuncture. Total AE incidence was 1.9%, and the incidence of AEs evaluated as certainly, probably or possibly causally related to acupuncture was 1.3%. Conclusions Acupuncture during pregnancy appears to be associated with few AEs when correctly applied.
