Background and objective: There is evidence that opioid initiation post-surgery is contributing to the problem of chronic misuse and/or abuse of over the counter medications in the community, and that orthopedic patients may be particularly at risk. The aim of the systematic review with meta-analysis was to identify research that examined opioid use at 3, 6, and 12 months post-operatively by previously opioid naïve orthopedic surgery patients.Design, databases, and data treatment: A searched review with meta-analysis was undertaken. Eight databases were search. Meta-analyses conducted at all three time points (3 months, 6 months, and 12 months).Results: The search yielded 779 records, and after screening, 13 papers were included in meta-analysis. Results provide strong evidence that post-operative opioid use amongst the opioid naïve is a real effect (7 percent at 3 months, 4 percent at 6 months, and 2 percent at 12 months). A Z-test for overall effect revealed strong evidence that this proportion was nonzero for opioid use at 3, 6, and 12 months (p 0.001 for all time points). A small but significant proportion of opioid naïve patients who are prescribed opioids remain on these medications up to 12 months post-operatively.Conclusions: The nature of the studies included in the meta-analysis were varied, hence subanalyses regarding surgery type, characteristics of the patient group or other potential factors that might influence the progression to longer term opioid use after these surgeries could not be explored. Given this, further research in this area should explore such specific orthopedic subgroups.

Abstract Background: Depression is one of the most common psychiatric disorders in the older adult and one of the most common risk factors for suicide in the older adult. Studies show different and inconsistent prevalence rates in Iran. This study aims to determine the prevalence of severe depression in Iranian older adult through a meta-analysis approach. Methods: The present meta-analysis was conducted between January 2000-August 2019. Articles related to the subject matter were obtained by searching Scopus, Sciencedirect, SID, magiran, Barakat Knowledge Network System, Medline (PubMed), and Google Scholar databases. The heterogeneity of the studies was evaluated using I 2 index and the data were analyzed in Comprehensive Meta-Analysis software. Results : In a study of 3948 individuals aged 50-90 years, the overall prevalence of severe depression in Iranian older adult was 8.2% (95% CI: 4.14-6.3%) based on meta-analysis. Also, in order to investigate the effects of potential factors (sample size and year of study) on the heterogeneity of severe depression in Iranian older adult, meta-regression was used. It was reported that the prevalence of severe depression in Iranian older adult decreased with increasing sample size and increasing years of the study, which is significantly different (P<0.05). Conclusion : Considering the high prevalence of severe depression in Iranian older adult, it is necessary for health policy makers to take effective control measures and periodic care for the older adult.

Abstract Background: Postoperative delirium (POD) is widely reported as a very common postoperative complication following total joint arthroplasty (TJA) of the hip and knee in elderly patients, leading to a variety of adverse effects. We sought to investigate predictors of delirium after TJA.Methods: PubMed, EMBASE, Cochrane Library, and Web of Science were searched up to May 2020 for studies examining POD following TJA in elderly patients. Pooled odds ratio (OR) and mean difference (MD) of those who experienced delirium compared to those who did not were calculated for each variable. The Newcastle-Ottawa Scale (NOS) was used for the study quality evaluation. Results: Fifteen studies with 31 potential factors were included in the meta-analysis. In the primary analysis, 9 factors were associated with POD, comprising advanced age (MD 3.81; 95% confidence interval (CI) 1.80–5.83), dementia (OR 24.85; 95% CI 7.26–85.02), hypertension (OR 2.26; 95% CI 1.31–3.89), diabetes (OR 2.02; 95% CI 1.15–3.55), stroke (OR 14.61; 95% CI 5.26–40.55), psychiatric illness (OR 2.72; 95% CI 1.45–5.08), use of sedative-hypnotics (OR 6.42; 95% CI 2.53–16.27), lower preoperative levels of hemoglobin (MD −0.56; 95% CI −0.89–−0.22), and lower preoperative mini-mental state examination score (MD −0.40; 95% CI −0.69–−0.12). Twelve studies were included in the systematic review, of which 24 factors were additionally correlated with POD using single studies.Conclusions: We identified predictors of POD in elderly patients following TJA. These findings may be used to identify patients with a high risk of delirium who are most likely to benefit from postoperative recovery.

Abstract Background Meta-analysis of RCTs has been widely employed to evaluate effectiveness of the interventions for breast cancer, but little is known of their reporting validity. Related studies showed that meta-analysis may mislead clinical practice when the reporting is uninformative. The purpose of the study was to assess the reporting quality of meta-analyses of RCTs for breast cancer intervention, and explore potential factors associated with the reporting.Method We searched Medline, Embase and Cochrane Database of Systematic reviews from inception to November 2019 for published meta-analysis of RCTs for breast cancer intervention. The PRISMA checklist (27-items) was used for the measuring of the reporting quality. The adherence of eligible meta-analyses under each reporting item from PRISMA were evaluated and those with an adherence ≥ 80% were regarded as well reported while less than 30% were poor reported. The proportion of reporting issues were summarized and compared in pre-defined settings measured by rate difference (RD).Result A total of 296 meta-analyses were included. For the 27 reporting items, there were only 6 items were identified as well-reported, while as much as 9 items were poorly reported by these meta-analyses. The reporting issues mainly embodied in the methods and results section. Our further analysis suggested that those published more recently (RD=-0.07, 95% CI: -0.12 to -0.03), complied with reporting guideline (RD=-0.04, 95% CI: -0.07 to -0.02), and pre-specified protocol (RD=-0.09, 95% CI: -0.09 to -0.01) were associated with less reporting issues.Conclusion The reporting of the meta-analyses for breast cancer intervention was uninformative to support the decision-making. Although improvement has seen over times, further efforts are still needed. Some easy-to-implement measures could be considered such as referring to a reporting guideline, develop a protocol in advance to help further researchers to improve the reporting of their meta-analysis.

Abstract Background: In the last decade, Africa has witnessed several outbreaks of Ebola virus disease (EVD), each presenting with varying case fatality rate (CFR) and other socio-economic impacts. This study aims to summarise the CFR and identify potential factors that influenced the severity of EVD outbreaks in Africa.Methods: This was a systematic review and meta-analysis of EVD outbreaks published between January 2010 and March 2020, using Web of Science, Scopus and PubMed databases. Only English articles and reports, including the number of cases and deaths during the outbreak in Africa, were considered. Quality of the included articles was assessed using the Murad’s quality assessment tool. The analysis was conducted using Stata (version 12), pooled effect sizes were calculated using the random-effects model and heterogeneity was tested for using the I2 statistic.Result: Thirteen studies with 32,300 cases and 13,727 deaths were identified whose pooled CFR was 60% (95% CI: 47-73%). The most EVD-affected countries were DRC with 5 outbreaks and a pooled CFR of 65% (95% CI: 59-71%), followed by Uganda with 3 outbreaks and CFR= 83% (95% CI: 60-99%). Zaire ebolavirus caused the most outbreaks (10), with a CFR= 58% (95% CI: 45-71%). Besides, outbreaks with less than 1000 cases reported a higher CFR rate compared to those with more cases.Conclusion: The study has revealed a considerably high CFR caused by the recurrent EVD outbreaks in Africa. It also notes an implementation gap of the prevention and control strategies, and thus identifies a need to strengthen the surveillance systems and response mechanisms to enable early detection and prompt control of future outbreaks.

The Relationship

Background. Some studies have shown the possible involvement ofHelicobacter pylori(H. pylori) infection in chronic urticaria, but the relationship remains controversial. The aim of this meta-analysis was to quantitatively assess the association betweenH. pyloriinfection and chronic urticaria.Methods. Observational studies comparing the prevalence ofH. pyloriinfection in patients with chronic urticaria and control subjects were identified through a systematic search in MEDLINE and EMBASE up to July 2014.H. pyloriinfection was confirmed by serological or nonserological tests. For subgroup analyses, studies were separated by region, publication year, andH. pyloridetection method to screen the potential factors resulting in heterogeneity.Results. 16 studies involving 965 CU cases and 1235 controls were included. Overall, the prevalence ofH. pyloriinfection was higher in urticarial patients than in controls (OR = 1.66; 95% CI: 1.12–2.45;P=0.01). This result persisted in subanalysis of nine high-quality studies (OR = 1.36; 95% CI: 1.03–1.80;P=0.03). Subgroup analysis showed that detection method ofH. pyloriis also a potential influential factor for the overall results.Conclusions. Our present meta-analysis suggests thatH. pyloriinfection is significantly, though weakly, associated with an increased risk of chronic urticaria.
