Varicose veins are among the common problems affecting the quality of life. Endovenous laser ablation (EVLA) has been introduced as a noninvasive treatment for varicose veins. This study was performed according to the Meta-analyses Of Observational Studies in Epidemiology (MOOSE) protocol, and the results were reported based on Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. MeSH keywords were searched in several online databases. Heterogeneity among studies was assessed using Cochran's Q test and I2 index, and the random-effects model. Data were analyzed using Comprehensive Meta-analysis software version 2. EVLA success, recurrence and recanalization rates were 94.5%, 10.3% and 3.6%, respectively. EVLA complications in the treatment of varicose veins were ecchymosis (41.3%), pain (26.1%), bruising (24.2%), induration (22.7%), edema (8.3%), phlebitis (4.8%), dyspigmentation (4.1%), venous thrombosis (3.7%), thrombophlebitis (3.7%), paresthesia (3.1%), thermal injury (1.8%), hematoma (1.7%), cellulitis (1.4%), bleeding (0.9%), infection (0.9%), nerve injury (0.9%), deep vein thrombosis (DVT) (0.6%) and pulmonary thromboembolism (PTE) (0.4%). The success rate of EVLA increased with an increase in wavelength and peaked at 1470 nm (nm). The highest rate of recurrence and recanalization was at 810 nm and 940 nm, and the lowest was at 1470 nm. EVLA is an effective, less invasive and mostly safe treatment with no need to general anesthesia and also minor complications. The follow-up duration and geographical location of studies also provide insight into the differences in success rate, recurrence and recanalization rate of EVLA. [ABSTRACT FROM AUTHOR]

An epidemic of infectious diseases such as COVID-19 can affect mental health, which may be associated with suicidal behaviors. This study was conducted based on the systematic review and meta-analysis methods for evaluating the prevalence of suicide ideation during COVID-19. This study used Preferred Systematic Review Reporting System and Meta-Analysis guideline and valid keywords. The articles related to the prevalence of suicide ideation during COVID-19 pandemic were obtained by searching among different databases including Scopus, Web of science, PubMed, ISC, Google scholar, SID, and Magiran. All of the articles published from the beginning of January 2020 to the end of May 2021 were reviewed. Among 478 articles screened, 377 articles were related to the studied topic, among which 38 articles were selected after assessing the title and abstract of which for reviewing the full text and finally 18 studies were included in the meta-analysis. Based on the results, the prevalence of suicide ideation and attempt among all studies were equal to 13% (95% confidence interval = 0.11-0.15, I2 = 99.7%, P = 0.00) and 1% (95% confidence interval = 0.00-0.01, I2 = 95.5%, P = 0.00), respectively. Based on the results, the prevalence of suicide attempt and ideation is possible during the COVID-19 pandemic. Therefore, health officials should pay attention to mental health issues in addition to the protective measures for preventing or reducing the infection with COVID-19. The increase of psychological consequences is probably related to the effect of lifestyle changes which associates with the spread of the disease. In the current meta-analysis performed, the prevalence of suicidal ideation and suicidal attempt was examined during the COVID-19 pandemic period and compared to the previous period without COVID-19. The effect of COVID-19 on suicidal ideation and suicidal attempt has never been studied. [ABSTRACT FROM AUTHOR]

Varicose veins are common disorders that affect the quality of life of sufferers due to the symptoms they cause. The efficacy of different varicose vein treatments has been studied extensively, with varying success rates. Less invasive treatments, such as sclerotherapy, can be mentioned among the proposed therapies. This study investigates the efficacy of ultrasound-guided foam sclerotherapy (UGFS) for treating varicose veins. In this study, the results were reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines of the Meta-analysis of Observational Studies in Epidemiology (MOOSE) protocol. By searching in 11 databases as well as the Google Scholar search engine using the keywords "varicose vein," "foam sclerotherapy," "occlusion," "success," "Duplex-guided foam sclerotherapy," "efficacy," and "Ultrasound-Guided Foam Sclerotherapy," randomized clinical trial (RCT) and cohort articles published until July 2022 were collected. The required information was extracted and analyzed using Comprehensive Meta-analysis (CMA) software version 2. Data analysis of 35 randomized clinical trial articles showed that the success rate of ultrasound-guided foam sclerotherapy in the treatment of varicose veins is 78% (95% CI: 73–83; P value < 0.001) (I2 = 89.11, P value < 0.001). The subgroup analysis showed that the success of this method is more in the form of sodium tetradecyl sulfate and polidocanol 2% foam and in a period of fewer than 3 months from the start of treatment and in the Asian race. Also, the analysis of 8 cohort studies showed that the success rate of ultrasound-guided foam sclerotherapy in the treatment of varicose veins is 81% (95% CI: 65–91; P value < 0.001). The most prevalent complications of this method in the treatment of varicose veins were induration, thrombophlebitis, bruising, dyspigmentation, hematoma, pain, and phlebitis. Present study illustrated that the effectiveness of ultrasound-guided foam sclerotherapy in the treatment of varicose veins is high. However, it was significantly less successful than published meta-analyses on other less invasive methods such as radiofrequency ablation (RFA) and endovenous laser ablation (EVLA). Also, this method showed more major complications than our previous study on the effect of endovenous laser ablation in the treatment of varicose veins. Factors such as foam type, follow-up duration, and racial differences can affect the study's results. [ABSTRACT FROM AUTHOR]

Varicose veins are a common disorder for which different treatments with varied efficacy have been introduced so far. In this study, we review the results of previous studies to evaluate the efficacy of ClosureFast endovenous radiofrequency ablation (RFA) in treating varicose veins. The present study was performed based on the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) protocols, and the results were reported based on the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guideline. Searches were conducted in all authentic online databases, and the retrieved papers were conducted until March 2021 using Mesh keywords. Study data with the necessary quality to enter the meta-analysis were extracted. Data were analyzed using comprehensive meta-analysis (CMA) software version 2. The cutoff level for significance was determined at 0.05. In total, 36 studies with sample size 7404 procedures were included. Radiofrequency ablation success, recurrence, and recanalization rates in the treatment of varicose veins were estimated to be 95%, 7%, and 3% respectively. The most common complications were bruising 13%, induration 11.6%, edema 8%, ecchymosis 7.4%, and numbness 6.3%. This study showed that the radiofrequency ablation method is a high-performance method with few and often transient complications, and the risk of significant complications in using this method to treat varicose veins is low. More studies are needed to evaluate the effectiveness of this method compared to other treatments. [ABSTRACT FROM AUTHOR]
