RESUMO
Background: Acute type A aortic dissection (ATAAD) still challenges physicians and warrants emergent surgical management. Two main methods to reduce cerebrovascular events in ATAAD surgeries are antegrade cerebral perfusion (ACP) and retrograde cerebral perfusion (RCP). We conducted a systematic review and meta-analysis to compare the outcomes of ACP and RCP methods during the ATAAD surgery. Methods: In this study, we searched the databases until March 29th, 2023. Studies that reported the data for comparison of different types of brain perfusion protection during aortic surgery in patients with ATAAD were included. Results: Twenty-six studies met the eligibility criteria. All studies had a low risk of bias as they were evaluated by the Joanna Briggs Institute (JBI) critical appraisal tool. Eventually, we included 26 studies in the current meta-analysis, and a total of 13,039 patients were evaluated. The calculated risk ratio (RR) for permanent neurologic dysfunction (PND) in ACP and RCP comparison was RR =1.23, 95% confidence interval (CI): (0.84, 1.80) (P value =0.2662), and in unilateral ACP (uACP) and bilateral ACP (bACP) was RR =1.2786, 95% CI: (0.7931, 2.0615) (P value =0.3132). When comparing the ACP-RCP and uACP-bACP groups, significant differences were found between ACP-RCP the groups in terms of circulatory arrest time (P value =0.0017 and P value =0.1995, respectively), cardiopulmonary bypass time (P value =0.5312 and P value =0.7460, respectively), intensive care unit (ICU)-stay time (P value =0.2654 and P value =0.0099), crossclamp time (P value =0.6228 and P value =0.2625), and operative mortality (P value =0.9368 and P value =0.2398, respectively), and when comparing the u-ACP and b-ACP groups for transient neurologic deficit (TND), an RR of 1.32, 95% CI: (1.05, 1.67) (P value =0.0199). The results showed high heterogeneity and no publication bias. Conclusions: This study demonstrated that the ACP and RCP are both safe and acceptable techniques to use in emergent settings. The uACP technique is equivalent to bACP in terms of PND and mortality, however, uACP is preferred over bACP in terms of TND.
RESUMO
BACKGROUND: Hotspot mutations occurring in the p110α domain of the PIK3CA gene, specifically p110αH1047R/L increase tumor metastasis and cell motility in triple-negative breast cancer (TNBC). These mutations also affect the transcriptional regulation of ΔNp63α, a significant isoform of the p53 protein involved in cancer progression. This study attempts to investigate the transcriptional impact of p110αH1047R/L mutations on the PIK3CA/ΔNp63α complex in TNBC carcinogenesis. METHODS: We performed site-directed mutagenesis to introduce p110αH1047R/L mutations and evaluated their oncogenic effects on the growth, invasion, migration, and apoptosis of three different TNBC cell lines in vitro. We investigated the impact of these mutations on the p110α/ΔNp63α complex and downstream transcriptional signaling pathways at the gene and protein levels. Additionally, we used bioinformatics techniques such as molecular dynamics simulations and protein-protein docking to gain insight into the stability and structural changes induced by the p110αH1047R/L mutations in the p110α/ΔNp63α complex and downstream signaling pathway. RESULTS: The presence of PIK3CA oncogenic hotspot mutations in the p110α/ΔNp63α complex led to increased scattering of TNBC cells during growth, migration, and invasion. Our in vitro mutagenesis assay showed that the p110αH1047R/L mutations activated the PI3K-Akt-mTOR and tyrosine kinase receptor pathways, resulting in increased cell proliferation, invasion, and apoptosis in TNBC cells. These mutations decreased the repressing effect of ΔNp63α on the p110α kinase domain, leading to the enhancement of downstream signaling pathways of PI3K and tyrosine kinase receptors and oncogenic transformation in TNBC. Additionally, our findings suggest that the physical interaction between the DNA binding domain of ΔNp63α and the kinase domain of p110α may be partially impaired, potentially leading to alterations in the conformation of the p110α/ΔNp63α complex. CONCLUSION: Our findings suggest that targeting the p110αH1047R/L mutations in TNBC could be a promising strategy for developing transcriptional-based therapies. Restoring the interaction between ΔNp63α and the p110α kinase domain, which is disrupted by these mutations, may provide a new approach to treating TNBC.

Recurrent IgA nephropathy (rIgAN) is an important cause of kidney allograft loss. Till now, no proven strategies have been confirmed to prevent/decrease the rIgAN. Here, a systematic review and meta-analysis were performed on the available interventions impacting rIgAN. PubMed, Embase, Web of sciences, ProQuest, and Cochrane library databases along with Google Scholar were searched for articles evaluating the rIgAN after kidney transplantation (up to 23 February 2023). The main inclusion criteria were kidney transplantation because of primary IgAN and articles studying the rate of the rIgAN based on different therapeutic interventions to find their effects on the disease recurrence. Based on our criteria, 11 papers were included in this systematic review, two of which pleased the criteria for the meta-analysis. Meta-analysis showed that the risk of the rIgAN in the steroid-free group was 3.33 times more than that of the steroid-receiving group (Pooled Hazard Ratio = 3.33, 95% CI 0.60 to18.33, Z-value = 1.38, p-value = 0.16). Steroid-free therapy increases the risk of rIgAN in kidney transplant recipients with primary IgAN. High-quality trials with large sample sizes studies are needed to confirm the impact of the steroids on decreasing the rate of the rIgAN.

Uterine leiomyosarcoma (uLMS) is an aggressive mesenchymal neoplasm associated with a poor prognosis. Systemic chemotherapy is the standard therapy for patients with uLMS. However, it is unclear which treatment regimen results in the most favorable clinical outcome. We performed a meta-analysis and meta-regression analysis to assess the efficiency of different treatments received by patients with advanced, metastatic, and relapsing uLMS by evaluating the objective response rate (ORR) and disease control rate (DCR) as primary endpoints. The frequentist random effects meta-analysis model was used to compare the outcomes of different treatment regimens for advanced uLMS. A meta-regression analysis was performed to estimate the association between the study-specific hazard ratios and specific demographic variables. A meta-analysis of 51 reports including 1664 patients was conducted. Among patients who received adjuvant chemotherapy (916 patients; 55%), gemcitabine and docetaxel were the most frequently used drugs. First-line monotherapy with alkylating agents (pooled ORR = 0.48; 95% confidence interval [CI]: 0.44-0.52) and second-line monotherapy with protein kinase inhibitors (pooled ORR = 0.45; 95% CI: 0.39-0.52) resulted in favorable prognoses. The combinations of anthracycline plus alkylating therapy (pooled DCR = 0.74; 95% CI: 0.67-0.79) and of gemcitabine plus docetaxel (pooled DCR = 0.70; 95% CI: 0.63-0.75) showed the greatest benefits when used as first-line and second-line chemotherapies, respectively. Subgroup meta-analysis results revealed that dual-regimen therapies comprising anthracycline plus alkylating therapy and gemcitabine plus docetaxel are practical therapeutic choices for International Federation of Gynecology and Obstetrics stages III-IVb with distant metastases when assessed by computed tomography (p = 0.001). Furthermore, neoadjuvant chemotherapy and local radiotherapy resulted in favorable outcomes for patients with earlier stages of distant relapsed uLMS (p < 0.001). Our findings provide a basis for designing new therapeutic strategies and can potentially guide clinical practice toward better prognoses for uLMS patients with advanced, metastatic, and relapsing disease.

Statement of the Problem: Xerostomia is a subjective sensation of dry mouth considered as a complex state affecting multiple oral functions. Pilocarpine may be a useful medication for the treatment of xerostomia, but its side effects limit its use under certain conditions. Recent studies have focused on the pilocarpine mouthwash as an alternative. Purpose: We have undertaken this study to review the latest available scientific evidence systematically, concerning the effects of pilocarpine mouthwash on salivary flow rate in patients with xerostomia. Materials and Method: An electronic search for randomized controlled trials published in English until September 2021 related to pilocarpine mouthwash and salivary flow rate in patients with dry mouth was performed in PubMed/Medline, Web of Science, Google Scholar, Embase, and Scopus. A random-effects meta-analysis was conducted to evaluate the relationship between the groups. Results: Two papers with 86 patients were selected for the final review based on strict eligibility criteria. According to the results of the meta-analysis, the mean visual analogue scale in the patient treated with pilocarpine mouthwash was 0.88 unit lower than that of the control group in the fourth week follow; however, it was not statistically significant (pooled mean difference=-0.88, 95% CI = (-2.72; 0.95), p= 0.34). Conclusion: It seems that the use of pilocarpine mouthwash can increase the salivary flow rates; however, no optimal dose and application regimen can currently be suggested due to the high heterogeneity of the data. Regarding the relief of the symptoms using pilocarpine mouthwash, the existing evidence does not support its effectiveness.
RESUMO
Background: Parkinson's disease can adversely affect the quality-of-life. Aims: We conducted a systematic review and meta-analysis of global literature on the quality-of-life of patients with Parkinson's disease and examined the association between patient characteristics and quality-of-life. Methods: We searched Embase, PubMed, Scopus and Web of Science from January 2000 to January 2020. We included articles published in English that used the Parkinson's disease questionnaire to estimate the quality-of-life score and to identify the determinants of quality-of-life in patients with Parkinson's disease. Results: In total, 41 studies with data from 4060 patients who had Parkinson's disease met our inclusion criteria. The overall quality-of-life score was 32.37 (95% confidence intervals (CI): 28.72-36.01). Age and duration of disease were inversely related to quality-of-life (P < 0.001). South America had the highest score on the questionnaire (39.73, 95% CI: 28.66-50.79, P < 0.001), indicating the lowest quality-of-life of patients with Parkinson's disease. Of the 6 World Health Organization regions, the Eastern Mediterranean Region had the highest score (36.28, 95% CI: 23.44-49.13, P < 0.001). Conclusion: Although the global score in patients with Parkinson's disease indicated an acceptable quality-of-life, there is a possibility for improvements. The findings of this study can inform evidence-based strategies by health policymakers and clinicians to enhance the quality-of-life of patients with Parkinson's disease.

BACKGROUND: Hematopoietic Stem Cell Transplantation (HSCT), is performed to treat many malignancies such as autologous or allogenic. Despite the success of this method in treating patients, - sometimes some HSCT recipients face problems such as cardiovascular complications. Therefore, this systematic review and meta-analysis aimed to evaluate the prevalence of cardiovascular complications in post-transplant patients. METHOD: In order to review the published studies, we examined PubMed, MEDLINE, Cochrane Library, Scopus, and web of science databases from the beginning to the end of January 2022, and we used tools by the Newcastle-Ottawa Scale to evaluate the quality of the studies. RESULT: In this study, 37 articles were included in the meta-analysis and 30,957 patients were examined. Also, the mean age of patients was 35.37 years. Based on the results of the meta-analysis, the prevalence of cardiovascular disease (CVD), was 16.84%. In addition, other complications related to CVD which include Arrhythmias, Congestive Heart Failure (CHF), Hypertension, stroke, and mortality were examined in patients who had hematopoietic stem cell transplantation and the resulting amounts were 3.91%, 3.66, 17.71, 0.22%, and 1.53%, respectively. CONCLUSION: This study showed that the prevalence of cardiovascular disease after hematopoietic stem cell transplantation is high and needs special attention.

BACKGROUND: This study was conducted to systematically review the existing literature examining the prevalence of anxiety among hospital staff and identifying the contributing factors to address the complications of this disorder and develop effective programmes for reducing the complications of this mental health problem. METHODS: We searched the electronic databases including PubMed, EMBASE, Scopus, Web of Science and Google Scholar from January 2020 to February 2021. To perform meta-analysis, the random effects model was used. To assess the statistical heterogeneity of the included studies, the I2 index was used, and 95% CI was estimated. Data analysis was performed by R software. RESULTS: In the final analysis, 46 articles with the total sample size of 61 551 hospital staff members were included. Accordingly, anxiety prevalence among healthcare workers (HCWs) was 26.1% (95% CI 19% to 34.6%). The prevalence rates of anxiety in health technicians and medical students were 39% (95% CI 13% to 73%) and 36% (95% CI 15% to 65%), respectively, indicating a much higher prevalence than other hospital staff members. Furthermore, a positive significant relationship between prevalence of anxiety among HCWs and their age was approved (p<0.001). The prevalence rate of anxiety was higher among women 37.7% (95% CI 25.4% to 51.8%) than men 27.2% (95% CI 18.2% to 38.6%). CONCLUSION: The findings show a moderately high prevalence rate of anxiety in hospital staff. Due to the high prevalence of this mental health problem in health technicians, medical students and frontline health workers, it is highly suggested that healthcare institutions offer mental health programmes for these working groups in order to appropriately manage anxiety during the COVID-19 pandemic.

Background: Behcet's disease (BD) is a chronic fatal illness with a relapsing remitting nature and significant organ-threatening morbidity and mortality. The aim of this research was to examine studies which were conducted on investigation of prevalence of quality of life among patients with Behcet's disease. Methods: A total of 13 articles were extracted from four main databases including PubMed, EMBASE, Scopus, and Web of Science from the onset of 2000 to January 2021. All studies published in English with the purpose of examining quality of life (QOL) among patients with BD or investigating its main determinants were included. Results: Totally, 1137 BD patients participated in 13 studies. Based on random effect analysis, the total score of physical health-related QOL was 46.7 (95% CI=41.26 to 52.13) and the total score of mental health-related QOL was 49.01 (95% CI=43.83 to 54.18) representing a moderate level of QOL among BD patients. Furthermore, weighted effect size analyses showed a significant correlation between QOL and variables such as patients' age, gender, disease duration and depression (pvalue: 0.00). Conclusion: As the symptoms of BD worsen over time, patients confront with more severe body pain, mobility restrictions, and difficulties in chewing, eating, speaking and swallowing which negatively affect social interactions of patients and reduce their QOL. Furthermore, depression was proved to act as a deteriorating factor for Health-Related Quality of Life (HRQOL) among BD patients. Thus, patients need to be psychologically supported by a specialized team and be informed during the course of treatment to gain useful information about the disease, treatment approaches and coping strategies.

RESUMO
Background: Needlestick injuries (NSIs) are one of the most serious occupational hazards for healthcare workers (HCWs). Aims: The aim of this study was to evaluate the incidence and causes of NSIs globally. Methods: A systematic review and meta-analysis of data from January 2000 to May 2020 collected from Scopus, PubMed, Embase, Web of Science, and Google Scholar. The Newcastle-Ottawa Scale was used to assess the quality of the included articles. The data obtained were analysed by R version 3/5/0, and 113 articles were retrieved. Results: There were 113 studies with a total of 525 798 HCWs. The incidence of NSIs was 43%. Africa had the highest rate of these injuries of 51%, and the World Health Organization (WHO) African Region had the highest incidence among WHO regions of 52%. Women were more frequently affected by NSIs than men. Hepatitis C virus infection was the disease most commonly transmitted via NSIs (21%). The highest rates of NSIs according to causes, devices, hospital locations, occupations and procedures were for recapping of needles, needles, general wards, nurses and waste disposal, respectively. Conclusion: The incidence of NSIs is gradually decreasing. The findings of this study can contribute to improving the decision-making process for reducing NSIs in HCWs.

BACKGROUND: This study was designed to conduct a systematic review and meta-analysis of existing literature examining the prevalence of depression among hospital staff and the impact of various factors with a view to organize related programs for reducing the complications of this mental disorder. METHOD: A total of 24 studies were extracted from a literature search conducted through electronic databases including PubMed, EMBASE, Scopus, and Web of Science from January 2019 to February 2021. FINDINGS: Following the extraction of data, the total number of hospital staff was reported to be 42,010. Based on the results, depression prevalence among them was 26% (95% Cl, 0.18-0.35). Furthermore correlation coefficients revealed a significant relationship between the rate of depression and variables including type of career, age, and gender (P-value < 0.05). The highest and lowest prevalence of depressive disorder among hospital staff was in Africa 82% (95% Cl, 0.35-0.97) and Asia 19% (95% Cl, 0.11-0.29). CONCLUSION: Our findings affirmed that female workers who aged between 29 and 35 and worked as administrative and support staff in hospitals were among the population being at higher risk of developing mental health problems during the COVID-19 pandemic.
RESUMO
According to the recent findings, autophagy modulation is being a potential therapeutic target in the management of ischemic stroke in a pre-clinical setting. However, the pros and cons of autophagic response strongly depend on the activation time of autophagy after injury. In this systematic review, we aimed to explore the impacts of pharmacological modulation of autophagy on infarct size in experimental ischemic stroke models. Based on our preliminary search, 3551 publications were identified. Of twenty-nine publications that met the inclusion criteria, twenty studies reported infarct volume reduction by percentage (%) with no evidence of any publication bias while nine studies reported by mm3, which had publication bias (39.25 units, standardized mean differences (SMD) = 41.92, 95% confidence interval (CI): 30.33 to 53.51). Based on a meta-analysis, the point estimate (pooled mean difference) for improvement of infarct volume during autophagy modulation according to the mm3 and percentage were 35.64 (mean differences (MD) = 35.64, 95% CI: 26.43 to 44.85, z-value = 7.58, p-value < 0.001) and 14.38 (MD = 14.38, 95% CI = 10.50 to 18.26, z-value = 7.26, p < 0.001) units, respectively. Despite the undeniable role of autophagy in ischemic stroke, the dichotomous effects of autophagy regarding infarct volume reduction should be taken into account. Based on our findings, the studies included in this meta-analysis mostly reported a negative relation between autophagy induction and stroke volume development due to over-activity of autophagy upon the severe ischemic stroke; therefore, further pre-clinical studies are also recommended to establish adjusted autophagy with considering a time-dependent effect as a promising therapeutic target.

OBJECTIVES: Percutaneous and transcutaneous posterior tibial nerve stimulation (PTNS and TTNS) showed a promising effect on overactive bladder (OAB) and interstitial cystitis/painful bladder syndrome. We aimed to give a systematic review and meta-analysis on the efficacy and safety of these therapeutic methods as well. METHODS: We searched studies available on PubMed, Embase, Cochrane, Scopus, Web of Science, and ProQuest on March 31, 2021, to find both published and unpublished studies. The retrieved articles were screened by two independent researchers and then the selected studies were critically appraised by Cochrane risk-of-bias tool for randomized trials, and Joanna Briggs Institute's checklist for quasi-experimental studies. Finally, the results of studies were synthesized using Review Manager (RevMan) 5.4 statistical software when the data were homogenous. The meta-analysis was performed by calculating the effect size (mean difference) and their 95% confidence intervals (CIs). RESULTS: Of the total 3194 publications, 68 studies were included in our qualitative evaluation and 9 studies (11 trials) in the quantitative stage. When TTNS or PTNS were compared to sham, placebo, no treatment, or conservative management, a decrease in frequency of urination was observed in both TTNS (mean difference [MD]: -3.18, 95% CI: -4.42 to -1.94, and p < 0.00001), and PTNS (MD: -2.84, 95% CI: -4.22 to -1.45, and p < 0.00001), and overall TTNS or PTNS (MD: -2.95, 95% CI: -4.01 to -1.88, and p < 0.00001). Significant improvements in mean voiding volume (MVV) and decreasing nocturia were also observed. CONCLUSIONS: Nerve stimulations either PTNS or TTNS appear to be effective interventions in treating refractory idiopathic OAB in terms of daily voiding frequency, MVV, urgency episodes, and nighttime voiding frequency. However, our result did not show any improvement in terms of urinary incontinence, postvoid residual volume or urge incontinence, and maximum cystometric capacity which emphasized the efficacy of these modalities on dry-OAB rather than wet-OAB.

BACKGROUND AND AIM: The purpose of this study was to evaluate the health-related quality of life (HRQOL) of patients with multiple sclerosis (MS) globally to provide precise information for policy makers to take necessary steps to improve the quality of life of these patients. This systematic review and meta-analysis is the first global study in the last decade. MATERIALS AND METHODS: Data from January 2000 to April 2020 were collected from Scopus, PubMed, Embase, Web of Science and Google Scholar databases on the basis of inclusion and exclusion criteria. Data obtained were analysed by R software, and 54 articles were finally included in the study. RESULTS: From the 2126 articles collected, a total of 54 articles were included in the study. Based on the results of random-effects analysis (DerSimonian and Laird), the mental HRQOL score was 55.18 (95% CI 52.71 to 57.65) and the physical HRQOL score was 48.72 (95% CI 45.93 to 51.52). In this study, age and duration of disease had a significant and direct relationship with mental HRQOL (p≤0.01). Moreover, mental HRQOL was higher in Europe than in other continents, while physical HRQOL was higher in Asia than in other continents. HRQOL was also evaluated on the basis of three valid questionnaires: Short Form 36, Multiple Sclerosis Quality of Life-54 and Multiple Sclerosis International Quality of Life. CONCLUSION: According to the results of this study, the total score for HRQOL indicates moderate quality of life. Factors such as depression, age and duration of disease have the greatest impact on HRQOL, whereas factors such as fatigue and the Expanded Disability Status Scale score have less effects on HRQOL, so that patients with MS continue their daily activities as long as they are physically able to, and this happens despite disease progression.

BACKGROUND AND AIM: Signs and symptoms of schizophrenia may have serious impacts on patients' quality of life leading to concern about different aspects of their lives. This study presents a systematic review and meta-analysis of the studies examining the quality of life among patients with schizophrenia and its relationship with patients' characteristics. MATERIALS AND METHODS: A total of 40 studies were extracted from searching of relevant databases published between 2000 and 2020. Descriptive data and correlation coefficients between patient's characteristics and quality of life were extracted and the results were reported according to Preferred Reporting Items for Systematic Reviews and Meta-analyses standards and meta-analysis of pooled studies. RESULTS: In total, 8363 patients with schizophrenia participated in 40 studies which used Schizophrenia Quality of Life Scale revision 4. The total score of quality of life (QOL) in the study subjects was reported to be 40.66. Weighted effect size analyses revealed a significant relationship between QOL and variables including patients' age and duration of the disease. Furthermore, the highest (the worst) score of QOL in schizophrenia patients was observed in Europe 47.04 (95% CI 41.26 to 52.82) and the Euro region 47.05 (95% CI 41.18 to 52.92). CONCLUSION: Overall, the QOL among patients with schizophrenia was in a good status, which could be improved through considering different life aspects of people living in various contexts. In fact, clarifying the determinants of QOL would be a key step in the provision of future treatment efforts.

This systematic review and network meta-analysis is aimed at investigating the effect of common surface treatments on the long-term repair bond strength of aged resin composite restorations and to rank and compare these surface treatments. In vitro studies evaluating the methacrylate-based resin composites subjected to rigorous aging protocols before and after being repaired with a new composite were included. A frequentist network meta-analysis was carried out using a random effects model. P scores were used to rank the efficacy of the surface treatments. Also, the global and node-split inconsistencies were evaluated. Web of Science, PubMed/Medline, Scopus, and Embase databases were searched until July 07, 2022. Twenty-six studies were included in the meta-analysis. The results showed that the application of silane and a total-etch (shear MD 32.35 MPa, 95% CI: 18.25 to 46.40, P score 0.95; tensile MD 33.25 MPa, 95% CI: 25.07 to 41.44; P score 0.77) or a self-etch (shear MD 38.87 MPa, 95% CI: 21.60 to 56.14, P score 0.99; tensile MD 32.52 MPa, 95% CI: 23.74 to 41.29; P score 0.73) adhesion protocol subsequent to the roughening with diamond bur produced the highest (micro)tensile and (micro)shear bond strengths compared to diamond bur alone as the control group. There was no difference between self- and total-etch adhesive protocols. Mechanical surface treatments yielded greater bond strength when used alongside the chemical adhesive agents. Further, it is possible to achieve acceptable repair bond strength using common dental clinic equipment. Therefore, clinicians could consider repairing old resin composites rather than replacing them.

Background: Anxiety affects social, economic, and physical aspects of daily life in patients with AIDS. Therefore, it is necessary to take preventive measures and design plans to maintain their general health. The present study was the first comprehensive systematic literature review research that examined the worldwide prevalence rate of anxiety in patients with AIDS. Methods: We searched for papers published in the English language in the major databases including Embase, PubMed, Web of Science, Scopus, Cochrane, and Google Scholar from 2000 to October 2018. There were 40 studies which found to be eligible. These studies were independently evaluated and the collected data were entered in a data extraction form, which was then analyzed by two authors and a third author if necessary. Der Simonian-Laird model was used to estimate the prevalence rate on a Forest plot at the interval confidence of 95%. Results: The total sample size was 24111, and the total number of people with anxiety was 5546. The results based on the random-effects model showed that the rate of anxiety prevalence in the patients was 25% (CI: 95%, 21% -30%) with heterogeneity of 97.9% and a significance level of p<0.001. The South America continent with a prevalence of 38% (95% CI, 34%-42%) had the highest anxiety prevalence rates and Africa with 19% (95% CI, 12% -29%) had the lowest anxiety prevalence rates. Conclusion: Based on findings, the prevalence of anxiety in developed countries was partially higher than in underdeveloped countries and the obtained mean in the present study. It can be a significant point for policymakers. Therefore, WHO and the world community should have special plans for these countries.
RESUMO
Background: Cancer-derived extracellular vesicles (EVs) are regarded to have significant function in most steps during cancer progression. This meta-analysis aims to investigate the accuracy of EVs as a biomarker in cancer diagnosis. Methods: The diagnostic efficacy of EVs for different cancers was assessed using pooled sensitivity and specificity, diagnostic odds ratio (DOR), and overall area under the curve (AUC) of the summary receiver operating characteristic (SROC). The positive likelihood ratio (PLR) and negative likelihood ratio (NLR) were verified to estimate the diagnostic efficacy of EV at a clinical level. Results: In all, 6,183 cancer patients and 2,437 healthy controls from 75 eligible studies reported in 42 publications were included in the study. The overall pooled sensitivity, specificity, PLR, NLR, and DOR were 0.62 (95% CI: 0.60-0.63), 0.76 (95% CI: 0.75-0.78), 3.07 (95% CI: 2.52-3.75), 0.34 (95% CI: 0.28-0.41), and 10.98 (95% CI: 7.53-16.00), respectively. Similarly, the AUC of the SROC was 0.88, indicating a high conservation of EVs as an early diagnostic marker. Furthermore, subgroup analysis suggested that the use of small EVs as a biomarker was more accurate in serum-based samples of nervous system cancer (p < 0.001). As a result, ultracentrifugation and quantification and size determination methods, such as Western blotting and ELISA were the most reliable identification methods for EV detection. We also indicated that increased secretion of EVs made them a capable biomarker for diagnosing cancer in elderly European individuals. Conclusions: Our study provides evidence that EVs are a promising non-invasive biomarker for cancer diagnosis. Well-designed cohort studies should be conducted to warrant the clinical diagnostic value of EVs.
