The Impact

IntroductionAttention-deficit hyperactivity disorder (ADHD) has been related to increased rates of unintentional injuries. However, the magnitude of the effect and to which extent variables such as sex, age or comorbidity can influence this relationship is unknown. Additionally, and importantly, it is unclear if, and to which degree, ADHD medications can decrease the number of unintentional injuries. Due to the amount of economic and social resources invested in the treatment of injuries, filling these gaps in the literature is highly relevant from a public health standpoint. Here, we present a protocol for a systematic review and meta-analysis to estimate the relationship between ADHD and unintentional injuries and assess the impact of pharmacological treatment for ADHDMethods and analysisWe will combine results from 114 bibliographic databases for studies relating ADHD and risk of injuries. Bibliographic searches and data extraction will be carried out independently by two researchers. The studies’ risk of bias will be assessed using the Newcastle-Ottawa Scale. Articles reporting ORs or HRs of suffering an injury in ADHD compared with controls (or enough data to calculate them) will be combined using Robust Variance Estimation, a method that permits to include multiple non-independent outcomes in the analysis. All analyses will be carried out in Stata. Age, sex and comorbid conduct disorders will be considered as potential causes of variance and their effect analysed through meta-regression and subgroup analysis. Sensitivity analyses will exclude articles with longer follow-ups, non-stringent definitions of ADHD or controls and statistically uncontrolled/controlled outcomes. Studies implementing a self-controlled case series methodology to investigate if ADHD drugs reduce the risk of injuries will be combined with a generalised linear mixed model using the Poisson distribution and a log link function.Registration detailsPROSPERO—Prospective Register of Systematic Reviews (CRD42017064967)

Introduction: Melanoma is a global disease that is predominant in Western countries. However, reliable data resources and comprehensive studies on the theragnostic efficiency of miRNAs in melanoma are scarce. Hence, a decisive study or comprehensive review is required to collate the evidence for profiling miRNAs as a theragnostic marker. This protocol details a comprehensive systematic review and meta-analysis on the impact of miRNAs on chemoresistance and their association with theragnosis in melanoma. Methods and analysis: The articles will be retrieved from online bibliographic databases, including Cochrane Review, EMBASE, MEDLINE, PubMed, Scopus, Science Direct, and Web of Science, with different permutations of ‘keywords’. To obtain full-text papers of relevant research, a stated search method will be used, along with selection criteria. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis for Protocols 2015 (PRISMA-P) standards were used to create this study protocol. The hazard ratio (HR) with a 95% confidence interval will be analyzed using Comprehensive Meta-Analysis (CMA) software 3.0. (CI). The pooled effect size will be calculated using a random or fixed-effects meta-analysis model. Cochran’s Q test and the I2 statistic will be used to determine heterogeneity. Egger’s bias indicator test, Orwin’s and the classic fail-safe N tests, the Begg and Mazumdar rank collection test, and Duval and Tweedie’s trim and fill calculation will all be used to determine publication bias. The overall standard deviation will be evaluated using Z-statistics. Subgroup analyses will be performed according to the melanoma participants’ clinicopathological and biological characteristics and methodological factors if sufficient studies and retrieved data are identified and available. The source of heterogeneity will be assessed using a meta-regression analysis. A pairwise matrix could be developed using either a pairwise correlation or expression associations of miRNA with patients’ survival for the same studies.

Abstract Iron metabolism and anemia may play an important role in multiple organ dysfunction syndrome in Coronavirus disease 2019 (COVID-19). We conducted a systematic review and meta-analysis to evaluate biomarkers of anemia and iron metabolism (hemoglobin, ferritin, transferrin, soluble transferrin receptor, hepcidin, haptoglobin, unsaturated iron-binding capacity, erythropoietin, free erythrocyte protoporphyrine, and erythrocyte indices) in patients diagnosed with COVID-19, and explored their prognostic value. Six bibliographic databases were searched up to August 3rd 2020. We included 189 unique studies, with data from 57,563 COVID-19 patients. Pooled mean hemoglobin and ferritin levels in COVID-19 patients across all ages were 129.7 g/L (95% Confidence Interval (CI), 128.51; 130.88) and 777.33 ng/mL (95% CI, 701.33; 852.77), respectively. Hemoglobin levels were lower with older age, higher percentage of subjects with diabetes, hypertension and overall comorbidities, and admitted to intensive care. Ferritin level increased with older age, increasing proportion of hypertensive study participants, and increasing proportion of mortality. Compared to moderate cases, severe COVID-19 cases had lower hemoglobin [weighted mean difference (WMD), − 4.08 g/L (95% CI − 5.12; − 3.05)] and red blood cell count [WMD, − 0.16 × 1012 /L (95% CI − 0.31; − 0.014)], and higher ferritin [WMD, − 473.25 ng/mL (95% CI 382.52; 563.98)] and red cell distribution width [WMD, 1.82% (95% CI 0.10; 3.55)]. A significant difference in mean ferritin levels of 606.37 ng/mL (95% CI 461.86; 750.88) was found between survivors and non-survivors, but not in hemoglobin levels. Future studies should explore the impact of iron metabolism and anemia in the pathophysiology, prognosis, and treatment of COVID-19.

BackgroundCoronavirus disease 2019 (COVID-19) has produced a significant health burden worldwide, especially in patients with cardiovascular comorbidities. The aim of this systematic review and meta-analysis was to assess the impact of underlying cardiovascular comorbidities and acute cardiac injury on in-hospital mortality risk.MethodsPubMed, Embase and Web of Science were searched for publications that reported the relationship of underlying cardiovascular disease (CVD), hypertension and myocardial injury with in-hospital fatal outcomes in patients with COVID-19. The ORs were extracted and pooled. Subgroup and sensitivity analyses were performed to explore the potential sources of heterogeneity.ResultsA total of 10 studies were enrolled in this meta-analysis, including eight studies for CVD, seven for hypertension and eight for acute cardiac injury. The presence of CVD and hypertension was associated with higher odds of in-hospital mortality (unadjusted OR 4.85, 95% CI 3.07 to 7.70; I2=29%; unadjusted OR 3.67, 95% CI 2.31 to 5.83; I2=57%, respectively). Acute cardiac injury was also associated with a higher unadjusted odds of 21.15 (95% CI 10.19 to 43.94; I2=71%).ConclusionCOVID-19 patients with underlying cardiovascular comorbidities, including CVD and hypertension, may face a greater risk of fatal outcomes. Acute cardiac injury may act as a marker of mortality risk. Given the unadjusted results of our meta-analysis, future research are warranted.

IntroductionMinimally invasive surgery in urology has grown considerably in application since its initial description in the early 1990s. Herein, we present the protocol for a systematic review and meta-analysis comparing open versus robotic urological oncological surgery for various clinically relevant outcomes, as well as to assess their comparative penetrance over the past 20 years (2000–2020).Methods and analysisWe will document the penetrance of robotic versus open surgery in the urological oncological field using a national database.Second, we will perform a systematic review and meta-analysis of all published full-text English and non-English language articles from Pubmed, Scopus and Web of Science search engines on surgical treatment of localised prostate, bladder, kidney and testis cancer published between 1st January 2000 to 10th January 2020. We will focus on the highest-volume urological oncological surgeries, namely, radical prostatectomy, radical cystectomy, partial nephrectomy, radical nephrectomy and retroperitoneal lymph node dissection. Study inclusion criteria will comprise clinical trials and prospective and retrospective studies (cohort or case–control series) comparing robotic versus open surgery. Exclusion criteria will comprise meta-analyses, multiple papers with overalapping study-periods, studies analysing national databases and case series describing only one approach (robotic or open). Risk of bias for included studies will be assessed by the appropriate Cochrane risk of bias tool. Principal outcomes assessed will include perioperative, functional, oncological survival and financial outcomes of open versus robotic uro-oncological surgery. Sensitivity analyses will be performed to correlate outcomes of interest with key baseline characteristics and surrogates of surgical expertise.Ethics and disseminationThis comprehensive systematic review and meta-analysis will provide rigorous, consolidated information on contemporary outcomes and trends of open versus robotic urological oncological surgery based on all the available literature. These aggregate data will help physicians better advise patients seeking surgical care for urological cancers.PROSPERO registration numberCRD42017064958.

Introduction: Thromboembolic risk stratification schemes and clinical guidelines for atrial fibrillation regard risk as independent of classification into paroxysmal (PAF) and nonparoxysmal atrial fibrillation (NPAF). The aim of the current study was to conduct a systematic review and meta-analysis evaluating the impact of AF type on thromboembolism, bleeding and mortality. Hypothesis: AF type would predict rates of thromebolism, mortality and bleeding. Methods: Pubmed was searched for randomized controlled trials, cohort studies, and case series reporting prospectively collected clinical outcomes stratified by AF type. The incidence of thromboembolism, mortality and bleeding was extracted. Results: AF clinical outcome data was extracted from 12 studies containing 99,996 patients. The pooled unadjusted risk ratio (RR) for thromboembolism in NPAF vs. PAF was RR 1.339 (95% CI: 1.140-1.644, P<0.001). In studies providing estimates of thromboembolism risk adjusted for baseline clinical risk factors, the pooled adjusted hazard ratio (HR) in NPAF vs. PAF was HR 1.384 (95% CI, 1.191-1.608, P<0.001). The pooled unadjusted risk ratio for all-cause mortality in NPAF vs. PAF was RR 1.462 (95% CI: 1.255-1.703 P<0.001). The pooled adjusted HR for all-cause mortality in NPAF vs. PAF was HR 1.217 (95% CI: 1.085-1.365, P<0.001. Rates of bleeding in NPAF and PAF were similar, unadjusted RR 1.00 (95% CI 0.919-1.087, P=0.994), pooled adjusted HR 1.025 (95% CI: 0.898-1.170, P=0.715). Conclusions: These data suggest a need for re-evaluation of the paradigm of thromboembolic risk equivalence between PAF and NPAF, and emphasize AF type as a powerful predictor of AF-related morbidity and mortality. Future studies exploring integration of AF type into thromboembolic risk models are needed.

Abstract Objectives We conducted a systematic review and meta-analysis to determine the magnitude of infection risk in patients with SLE and evaluate the effect of general and SLE-related factors on infection risk. Methods We searched MEDLINE and Embase from inception to July 2018, screening for observational studies that evaluated infection risk in patients with SLE compared with the general population/healthy controls. Outcomes of interest included overall severe infection, herpes zoster infection/reactivation, opportunistic infections, pneumonia and tuberculosis. Random-effects models were used to calculate pooled risk ratios (RRs) for each type of infection. Sensitivity analysis assessed the impact of removing studies with high risk of bias. Results Eleven retrospective or prospective cohort studies were included in the meta-analysis: overall severe infection (n = 4), pneumonia (n = 6), tuberculosis (n = 3) and herpes zoster (n = 2). Pooled RRs for overall severe infection significantly increased for patients with SLE compared with the general population/healthy controls [RR 2.96 (95% CI 1.28, 6.83)]. Pooled RRs for pneumonia, herpes zoster and tuberculosis showed significantly increased risk compared with the general population/healthy controls [RR 2.58 (1.80, 3.70), 2.50 (2.36, 2.65) and 6.11 (3.61, 10.33), respectively]. Heterogeneity and evidence of publication bias were present for all analyses, except herpes zoster. Sensitivity analyses confirmed robustness of the results. Conclusion Patients with SLE have significantly higher risk of infection compared with the general population/healthy controls. Efforts to strengthen strategies aimed at preventing infections in SLE are needed. Protocol registration PROSPERO number: CRD42018109425.

ObjectiveTo assess the epidemiological association of smoking status and tinnitus with a systematic review and meta-analysis and to estimate the population attributable risk in Germany.Data sourcesA systematic literature search in PubMed and ISI-Web of Science Core Collection resulted in 1026 articles that were indexed until 15 September 2015. Additionally, proceedings of the international tinnitus seminars and reference lists of relevant articles were screened.Study selectionTwo reviewers searched independently for epidemiological studies. Tinnitus as a manifestation of tumours, vascular malformations, specific syndromes or as a consequence of surgical and medical treatment was not considered. Moreover, studies conducted among patients of ear, nose and throat clinics were excluded.Data extractionIf only raw data were provided, effect sizes were calculated. Further unpublished data were received by corresponding authors.Data synthesisData of 20 studies were pooled. Current smoking (OR 1.21, 95% CI 1.09 to 1.35), former smoking (OR 1.13, 95% CI 1.01 to 1.26) and ever smoking (OR 1.20, 95% CI 1.11 to 1.30) were significantly associated with tinnitus. Moreover, sensitivity analyses for severe tinnitus (OR 1.32, 95% CI 1.10 to 1.58) and for studies of superior quality (OR 1.15, 95% CI 1.03 to 1.29) showed increased risks. According to this, the population attributable risk estimate in Germany is 3.5%.ConclusionThere is sufficient evidence that smoking is associated with tinnitus. As the review mainly consists of cross-sectional studies, the observed correlation does not give evidence of a causal relationship. Due to the impact of various confounders, further research is needed to provide more evidence on the strength of association and causal relationships.

Abstract Abstract Background: In recent years, several studies have investigated the impact of miR-155 on the diagnosis and prognosis of LCa, but results of these researches were still controversial due to insufficient sample size. Thus, we carried out this systematic review and meta-analysis to figure out whether miR-155 could be a screening tool in the detection and prognosis of LCa. Methods: A meta-analysis of 13 articles with 19 studies was performed by retrieving the PubMed, Embase and other bibliographic databases. We screened all correlated literaters until December 1st, 2018. For the diagnostic value of miR-155 in LCa, SEN, SPE, PLR, NLR, DOR and AUC were pooled to evaluate the accuracy of miRNA-155 in the diagnosis of LCa. Subgroup and meta-regression analyses were performed to distinguish the potential sources of heterogeneity between studies. For the prognositic value of miR-155 in LCa, the pooled HRs and 95% CIs of miRNA-155 for OS and DFS/ PFS were calculated. Results: For the diagnosis analysis of miR-155 in LCa, the pooled SEN and SPE were 0.82 (95% CI: 0.72-0.88) and 0.78 (95% CI: 0.71-0.84), respectively. Besides, the pooled PLR was 3.75 (95% CI: 2.76-5.10), NLR was 0.23 (95% CI: 0.15-0.37), DOR was 15.99 (95% CI: 8.11-31.52) and AUC was 0.87 (95% CI: 0.84-0.90), indicating a significant value of miR-155 in the LCa detection. For the prognostic analysis of miR-155 in LCa, up-regulated miRNA-155 expression was not significantly associated with a poor OS (pooled HR = 1.26, 95% CI: 0.66-2.40) or DFS/PFS (pooled HR = 1.28, 95% CI: 0.82-1.97). Conclusions: This meta-analysis demonstrated that miR-155 could be used as a potential biomarker in the diagnosis of LCa but not an effective biomarker for predicting the prognosis of LCa. Furthermore, more well-designed researches with larger cohorts were warranted to confirm the value of miR-155 for the diagnosis and prognosis of LCa.

Abstract Aim All Neck of Femur fracture patients have a significant 30 – day mortality despite efforts to improve their outcomes. Incidence of NOF cases remained high during the pandemic in the UK and as a result numerus cases were complicated with SARS-CoV-2 infection. We performed a systematic review and meta-analysis of all UK published studies related to NOF fractures and 30-day mortality outcomes during the COVID 19 pandemic. Method A systematic review and meta-analysis was performed and reported as per the PRISMA checklist. Two reviewers independently searched on Medline for UK studies that were published between 1stof March 2020 and 1stof November 2020. Outcomes compared were 30-day mortality, time to surgery and anaesthetic risk. Results A total of 5 articles were included in our study. These studies were all case series with evidence level 3 or 4. A total of 286 patients complicated with COVID infection with a range of 30-day mortality 30.5%-50%. OR 6.02(95CI: 4.10-8.85), Chi24.82, I2 58%. Increased time to surgery due to Coronavirus related delays was also noted for the majority of studies. Mortality scores (Charlson Comorbidity Index, Nottingham Hip fracture score) failed to accurately predict the mortality risk. Conclusions Concurrent infection of COVID -19 in patients with NOF fractures increases the 30-day mortality 6 times compared to the negative group. Efforts should be made to optimise time to surgery as well as postoperative care via higher dependency units. Updates in mortality predicting scores is deemed necessary to include the SARS-CoV-2 infection as a factor.
