MicroRNAs utilization as effective factors on hematopoietic stem cell transplantation, its outcomes and prognosis; a comprehensive systematic review.

INTRODUCTION: The therapeutic method for many malignant and non-malignant diseases is hematopoietic stem cell transplantation (HSCT), but it is not always fully successful in all patients. Indeed, HSCT can be influenced by a variety of factors. Here we reviewed the effect of microRNAs (miRs) on HSCT-related outcomes, like survival, infections, relapse, engraftment, and so on, systematically. METHOD: WOS, Scopus, PubMed, Google Scholar, and ProQuest databases were searched. The PRISMA guideline was performed, and 24 studies were included through quality assessment. Classified data extraction was done based on the type of disease. RESULTS: The systematic review identified 47 miRs effective on HSCT. The role of miRs as tumor suppressors or oncogenes is reported in acute myeloblastic and lymphoblastic leukemia patients undergoing HSCT due to their effects on overall or event-free survival. Additionally, relapse after HSCT in multiple myeloma is correlated with miRs expression. Also, recovery from post-autologous HSCT cytopenia or platelet and neutrophil engraftment can be influenced by miRs. We highlighted here reports on specific miRs. CONCLUSION: We reported prognostic miRs for in-depth clinical management of the HSCT process and its outcomes. Also, miRs are introduced for the prevention of HSCT-related complications, and future studies are suggested to evaluate personalized medicine's utilization of miRs in therapeutic methods like HSCT in neoplasia.

CircRNAs in diagnosis, prognosis, and clinicopathological features of multiple myeloma; a systematic review and meta-analysis.

Unlike improved treatment response in multiple myeloma (MM), the mortality rate in MM is still high. The study's aim is to investigate the potential role of circRNAs as a new biomarker for diagnosis, prognosis, and clinicopathological features of MM. We identified studies through Web of Science, Scopus, PubMed and ProQuest databases, and Google Scholar to August 2022. The SEN, SPE, PLR, NLR, DOR, and AUC were combined to investigate the diagnostic performance of circRNAs in MM. Also, HR and RR were used for prognostic and clinicopathological indicators, respectively. 12 studies for prognosis, 9 studies about diagnosis, and 13 studies regarding clinicopathological features. The pooled SEN, SPE, DOR, and AUC were 0.82, 0.76, 14.70, and 0.86, respectively for the diagnostic performance of circRNAs. For the prognostic performance, oncogene circRNAs showed a poor prognosis for the patients (HR = 3.71) and tumor suppressor circRNAs indicated a good prognosis (HR = 0.31). Finally, we discovered that dysregulation of circRNAs is associated with poor clinical outcomes in beta-2-microglobulin (RR = 1.56), Durie-Salmon stage (RR = 1.36), and ISS stage (RR = 1.79). Furthermore, the presence of del(17p) and t(4;14) is associated with circRNA dysregulation (RR = 1.44 and 1.44, respectively). Our meta-analysis demonstrates that the expression analysis of circRNAs is valuable for MM's diagnosis and prognosis determination. Also, dysregulation of circRNAs is associated with poor clinicopathological features and can be used as the applicable biomarkers for evaluating treatment effectiveness.

Prevalence and factors associated with pressure injury in patients undergoing open heart surgery: A systematic review and meta-analysis.

Pressure injuries (PIs) are one of the major and costliest medical problems with severe implications for patients. Cardiovascular surgery patients are at the higher risk of developing surgery-related PIs. So this study was conducted with the aim of investigating the prevalence and factors associated with PIs in patients undergoing open heart surgery. We identified articles through electronic databases such as Web of Science, Scopus, PubMed, ProQuest; and Persian Databases: SID, Magiran and Irandoc without restriction on language or publication period (from inception through June 2022). Finally, 17 studies that fulfilled eligibility criteria were included in final systematic review and meta-analysis. Data analyses were conducted using STATA version 14. The pooled prevalence of PI in patients undergoing open heart surgery was 24.06% (95% CI: 17.85-30.27). High heterogeneity was observed across the included studies (I2  = 96.0, P < 0.000). The prevalence by gender was reported as 25.19% (95% CI: 13.45-36.93) in men and 33.36% (95 CI%: 19.99-46.74) in women. The result showed there was statistically significant association between PI and Female sex (Pooled Est: 1.551, 95% CI: 1.199-2.006, z = 3.345, P = 0.001), diabetes (Pooled Est: 1.985, 95% CI: 1.383-2.849, z = 3.719, P = 0.000), advanced age (SMD: 0.33 years; 95% CI: 0.09-0.57), Duration of surgery (SMD: 0.47; 95% CI: 0.19-0.75) and preoperative serum albumin level (SMD: 0.56; 95% CI: 0.14-0.98). The relatively high PIs incidence among patients undergoing open heart surgery suggests that typical PI prevention methods are insufficient for this population. Targeted prevention measures must be developed and implemented.

Assessing abstracts of Iranian systematic reviews and metaanalysis indexed in WOS and Scopus using PRISMA.

Background: Systematic reviews and meta-analysis have significant advantages over conventional reviews in that all available data should be presented. This study aimed to evaluate Iranian systematic reviews and meta-analysis abstracts indexed in WOS and Scopus during 2003-2012 based on PRISMA checklist. Methods: This is an analytical study. We evaluated 46 article abstracts indexed in WOS, 89 article abstracts indexed in Scopus and 158 article abstracts indexed in WOS and Scopus both (overlapped group). The quality of the abstracts was evaluated according to the PRISMA checklist for abstracts. Some indicators including distribution per year, total citation, average citations per year, average citations per documents and average citations per year in each article were determined through searching the WOS and Scopus Databases' analytical section. Then, the correlations between the abstract's PRISMA scores, average citations per year, and publication year were calculated. Results: The abstract's quality is not desirable as far as the PRISMA criteria are concerned. In other words, none of the articles' abstracts is in line with the PRISMA items. The average of scores of the current study was 5.9 while the maximum score was 12. The PRISMA criteria showed the highest compliance with "Objectives" (98.6%), the second highest with "Synthesis of result" (85%) and "Title" (80.2%) and the lowest compliance with "Registration" (2%). There was a positive correlation between the compliance of PRISMA score and the average citations per year while there was a negative correlation between PRISMA score and the publication year. Conclusion: It seems that the suggested criteria for reporting Iranian systematic reviews and meta-analysis are not considered adequately by the writers and even scientific journal editors.

Preventing pressure injury in open-heart surgical patients: A systematic review.

Background: Cardiac surgical patients are highly prone to developing surgery-related Pressure injuries (PIs). Prevention of PIs is an important patient safety priority in healthcare settings and patients care. So the aim of this study is to detect the effectiveness of prevention strategies to decrease PIs prevalence and incidence in patients undergoing open heart surgery. Method: We identified studies through Web of Science, Scopus, PubMed, Cochrane, and ProQuest databases from inception through September 2022 with restrictions on the English language. Cochrane RoB 2, JBI, and NIH checklist were carried out as critical appraisal Tools to investigate the studies risk of bias. Finally, 10 studies with a total sample No. 1348, which fulfilled eligibility criteria were included in final systematic review. Result: Most common interventions investigated in included studies were addressing impairments skin care which included the use of multilayer silicone foam, Care bundle and multiple intervention programs, alternative head inflatable pads, pressure-reducing foam mattresses, and electric bed frames as the effective PIs Prevention (PIP) strategies. While repositioning is one of the important causes mentioned in most PIP protocols, there was not adequate evidence to recommend any special turning regimens for PIP. Conclusion: Given current evidence, multilayer silicone foam, Care bundle and multiple intervention programs, alternative inflatable head pads, pressure-reducing foam mattresses, and electric bed frames are effective strategies to prevent pressure ulcers. Further investigations are needed to specify the cost-effectiveness of mentioned strategies and RCTs to determine other PIP strategies such as repositioning and mobilization, nutritional supplementation, creams, and co-interventions effects.
