Ubiquitin-specific proteases (USPs) in leukemia: a systematic review.

BACKGROUND: Leukemia, a type of blood cell cancer, is categorized by the type of white blood cells affected (lymphocytes or myeloid cells) and disease progression (acute or chronic). In 2020, it ranked 15th among the most diagnosed cancers and 11th in cancer-related deaths globally, with 474,519 new cases and 311,594 deaths (GLOBOCAN2020). Research into leukemia's development mechanisms may lead to new treatments. Ubiquitin-specific proteases (USPs), a family of deubiquitinating enzymes, play critical roles in various biological processes, with both tumor-suppressive and oncogenic functions, though a comprehensive understanding is still needed. AIM: This systematic review aimed to provide a comprehensive review of how Ubiquitin-specific proteases are involved in pathogenesis of different types of leukemia. METHODS: We systematically searched the MEDLINE (via PubMed), Scopus, and Web of Science databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA) to identify relevant studies focusing on the role of USPs in leukemia. Data from selected articles were extracted, synthesized, and organized to present a coherent overview of the subject matter. RESULTS: The review highlights the crucial roles of USPs in chromosomal aberrations, cell proliferation, differentiation, apoptosis, cell cycle regulation, DNA repair, and drug resistance. USP activity significantly impacts leukemia progression, inhibition, and chemotherapy sensitivity, suggesting personalized diagnostic and therapeutic approaches. Ubiquitin-specific proteases also regulate gene expression, protein stability, complex formation, histone deubiquitination, and protein repositioning in specific leukemia cell types. CONCLUSION: The diagnostic, prognostic, and therapeutic implications associated with ubiquitin-specific proteases (USPs) hold significant promise and the potential to transform leukemia management, ultimately improving patient outcomes.

Prevalence of asthma among children and adolescents in WHO's Eastern Mediterranean Region: a meta-analysis of over 0.5 million participants.

OBJECTIVE: This study aims to evaluate the epidemiology of asthma among children and adolescents in the Eastern Mediterranean Region. METHODS: Exhaustive searches were conducted across databases, including PubMed, Scopus, Web of Knowledge Core Collection, Embase, and Google Scholar. The selection criteria included studies reporting asthma prevalence in individuals aged 0 to 19 years, using validated questionnaires. Data were extracted and synthesized using the DerSimonian and Laird random effects model. RESULTS: The overall prevalence of asthma in Eastern Mediterranean Regional Office (EMRO) countries, among the 514,468 children and adolescents included in this meta-analysis, was 10.61%, synthesized from 95 studies. Among the countries studied, Qatar exhibited the highest prevalence at 16.69%, followed by Saudi Arabia at 16.57%, Iraq at 16.22%, Oman at 15.20%, and Afghanistan at 14.90%. Adolescents showed a slightly higher prevalence of asthma at 10.10% compared to children at 9.70%. Boys exhibited a higher prevalence at 11.48% compared to girls at 9.75%. Urban areas demonstrated a higher prevalence at 11.27% than rural areas at 8.29%. CONCLUSION: Efforts to reduce asthma prevalence in Arab countries and address underdiagnosis in African nations within the EMRO are crucial. Targeted interventions should focus on addressing environmental triggers and improving access to healthcare. Enhanced diagnostic capabilities and healthcare infrastructure are necessary in African countries. Collaborative action is essential to alleviate the asthma burden and promote respiratory health across the EMRO region.

Prevalence of needle-stick injury in Iranian nurses: an updated systematic review and meta-analysis of observational studies.

BACKGROUND: The aim of this study was to conduct a systematic review and meta-analysis to estimate the prevalence of needle-stick injury among Iranian nurses. METHODS: We conducted a systematic review and meta-analysis to estimate the prevalence of needle-stick injury among Iranian nurses. A comprehensive search of Web of Science, PubMed, Scopus, Scientific Information Database, and MagIran was performed, yielding 29 observational articles comprising 8842 nurses. The studies ranged from 2006 to 2023, with sample sizes varying from 68 to 1555 individuals. Methodological quality was assessed using the Strengthening the Reporting of Observational Studies in Epidemiology checklist. The pooled prevalence was calculated using the random-effects model, and subgroup analyses were conducted based on hospital type and gender. The data was analyzed using Stata software version 16. RESULTS: The pooled prevalence of needle-stick injury among Iranian nurses was found to be 46% (95% Confidence Interval [CI]: 39-53%). Subgroup analysis revealed significant difference in prevalence between teaching hospitals (47%; 95% CI: 39-54%) and military hospitals (38%; 95% CI: 31.1-44%). The prevalence of NSI in region 1 (Tehran and surrounding provinces) and other regions was 45.1% (95% CI: 37-54%) and 49.17% (95% CI: 36.5-61.7%). Gender-based analysis showed higher prevalence in women (58%; 95% CI: 44-71%) compared to men (55%; 95% CI: 43-66%). CONCLUSION: Needle stick injuries has a high prevalence among Iranian nurses, especially nurses working in teaching hospitals. Therefore, it seems necessary to use interventions to reduce it.

The Effect of COVID-19 Lockdown Among Adolescents with Type 1 Diabetes: A Systematic Review and Meta-Analysis.

OBJECTIVE: The aim of this study was to assess how the lockdown of the COVID-19 pandemic had affected the glycaemic control of adolescents aged 10-19 with type 1 diabetes. METHODS: A comprehensive search of literature was performed in PubMed, Scopus, Web of Science, and ProQuest. Published articles up to September 2022 were included. The Glucose Monitoring Index (GMI) and HbA1c level were defined as outcome variables. Average glucose level was found to be a common variable in both HbA1c levels and GMI; therefore, HbA1c and GMI were converted to average glucose (mg/dL) using appropriate formulas. Studies reported the outcomes in two or three periods (pre-lockdown, lockdown, and post-lockdown) were included in the analysis. A paired wise meta-analysis was performed among the studies that reported all three periods. Homogeneity across studies was assessed using I2 statistic. RESULT: Fourteen studies were included in the study. The pooled average glucose during the lockdown decreased to 166.9 mg/dL (95% CI, 153.78, 180.02) from 205.793 mg/dL (95% CI, 188.412, 223.173) during the pre-lockdown period, then it increased to 204.23 mg/dL (95% CI, 186.17, 222.29) during the post-lockdown period. A paired wise meta-analysis indicated a reduction in average glucose levels. However, it was not statistically significant, possibly due to the small number of studies that reported data from all three periods. CONCLUSION: Although the descriptive analysis of our study showed that the lockdown had affected (decreased) the average glucose level among adolescents with type 1 diabetes, this was not statistically significant in the pooled analysis.

ChecKAP: A Checklist for Reporting a Knowledge, Attitude, and Practice (KAP) Study.

INTRODUCTION: The Knowledge, Attitudes, and Practices (KAP) model is a foundational tool in public health research. KAP surveys play a vital role in this process by gauging a population's current level of knowledge about a specific health issue. Rigorous evaluation is essential for ensuring the validity and reliability of KAP studies. Therefore, in this study, a comprehensive checklist for reporting Knowledge, Attitude, and Practices (KAP) Studies was developed. METHODOLOGY: This study was conducted using a systematic six-step roadmap. A comprehensive review of available relevant quality assessment tools led to the development of specific new items. An expert panel reviewed the initial draft, and after corrections were made, the second draft was finalized and subjected to psychometric analysis by experts. RESULTS: The development of ChecKAP (Checklist for Reporting Items for Knowledge, Attitude, and Practice) represents a significant contribution to KAP studies. The final tool consists of 46 items across 8 fields: title (1 item), abstract (6 items), keywords (1 item), introduction (6 items), method (11 items), findings (7 items), discussion (15 items), and conclusion (1 item). CONCLUSION: ChecKAP assesses the inherent complexity of KAP research methods and ensures consistent reporting. It fills an important gap in the KAP research literature and serves a dual purpose. First, it acts as a quality assessment tool for reviewers, enabling them to evaluate the methodological rigor and clarity of submitted manuscripts. Second, it serves as a guideline for authors, promoting a more systematic and transparent approach to reporting.

Comprehensive analysis of the role of ubiquitin-specific peptidases in colorectal cancer: A systematic review.

BACKGROUND: Colorectal cancer (CRC) is the third most frequent and the second most fatal cancer. The search for more effective drugs to treat this disease is ongoing. A better understanding of the mechanisms of CRC development and progression may reveal new therapeutic strategies. Ubiquitin-specific peptidases (USPs), the largest group of the deubiquitinase protein family, have long been implicated in various cancers. There have been numerous studies on the role of USPs in CRC; however, a comprehensive view of this role is lacking. AIM: To provide a systematic review of the studies investigating the roles and functions of USPs in CRC. METHODS: We systematically queried the MEDLINE (via PubMed), Scopus, and Web of Science databases. RESULTS: Our study highlights the pivotal role of various USPs in several processes implicated in CRC: Regulation of the cell cycle, apoptosis, cancer stemness, epithelial-mesenchymal transition, metastasis, DNA repair, and drug resistance. The findings of this study suggest that USPs have great potential as drug targets and noninvasive biomarkers in CRC. The dysregulation of USPs in CRC contributes to drug resistance through multiple mechanisms. CONCLUSION: Targeting specific USPs involved in drug resistance pathways could provide a novel therapeutic strategy for overcoming resistance to current treatment regimens in CRC.

Background: The objective of this study was to develop a guideline on how to report result of a population-based cancer registry. Methods: The guideline's development involved a core working committee and a scientific committee comprising experts from diverse domains. The process comprised three steps: 1) a comprehensive review of existing tools and guidelines and the development of the initial draft of the guideline based on a review of literature, 2) refinement items through several rounds of focus group discussion among the core group, and development initial draft, and 3) Evaluation of the initial draft by scientific committee members. Items in the guideline were organized to accommodate reports of population-based cancer registries as a scientific manuscript. Results: The core committee developed 47 items distributed in the major heading of a scientific manuscript presented as a checklist. The evaluation of the scientific committee led to a consensus on the majority of the items included in the checklist. Among 10 committee members, 7 provided unreserved approval, validating each item's necessity, applicability, and comprehensibility in the checklist. Feedback from the remaining 3 members was carefully analyzed and integrated to enhance the guideline's robustness. Incorporating feedback, a first final draft was presented in a meeting of scientific and core working committee members. Collaborative discussion ensured clarity of expression for each items and a final checklist was developed. Conclusion: The guideline abbreviated as REPCAN offers a standardized framework for reporting population-based cancer registry, fostering transparency, comparability, and comprehensive data presentation. The guideline encourages flexibility while promoting comprehensive and robust reporting practices.

The impact of cultural healthcare practices on Children's health in the United Arab Emirates: a qualitative study of traditional remedies and implications.

Aim: This qualitative study investigates the impact of cultural practices on children's health in the United Arab Emirates (UAE) by examining the use of traditional remedies and home treatments by mothers. Methods: Twenty-five participants, all mothers who had employed traditional treatments or home remedies for their children during periods of illness, were included in the study. The participants represented a diverse range of educational backgrounds, from school diploma holders to university degree graduates, with ages spanning from 20 to 50 years. Hailing from different Arabic countries and cultural subgroups, the majority of participating mothers were from the UAE. Results: Through in-depth interviews, three major themes emerged from the participants' experiences. Firstly, a strong connection between culture, religion, and healthcare practices was evident. Many mothers opted for cultural remedies as their first line of defense against illnesses due to the practices' strong foundations in their cultural heritage. Herbal remedies, Quranic healing, and other traditional methods were perceived to be both effective and spiritually comforting, reinforcing participants' sense of cultural identity. Secondly, participants highlighted unintended consequences of relying solely on traditional treatments. Some instances were reported where the use of ineffective remedies resulted in delays in seeking appropriate medical care for their children, potentially compromising their health. Additionally, certain misconceptions regarding the safety and efficacy of traditional remedies were identified, emphasizing the need for evidence-based healthcare education. Conclusion: This qualitative study sheds light on the intricate interplay between culture, traditional remedies, and children's health in the UAE. The incorporation of diverse participants from various Arabic countries and cultural subgroups enriches the study's applicability to broader Arabic cultures. By recognizing the significance of cultural healthcare practices and striking a balance with evidence-based care, healthcare providers can create a more inclusive and effective healthcare environment for children in the UAE. Future research should explore diverse samples and develop targeted interventions to further advance cultural awareness and understanding in healthcare practices.

Prevalence of Undiagnosed Attention Deficit Hyperactivity Disorder (ADHD) Symptoms in the Young Adult Population of the United Arab Emirates: A National Cross-Sectional Study.

BACKGROUND: Attention deficit hyperactivity disorder (ADHD), a globally prevalent behavioural disorder, remains underdiagnosed, particularly among adults. This issue is exacerbated in the Arab region due to stigma and insufficient healthcare facilities and professionals. Despite the United Arab Emirates (UAE) efforts to improve mental healthcare, shortcomings persist. No studies in the UAE currently assesses the appropriateness of the screening system for ADHD and other behavioural issues. Furthermore, prevalence rates of ADHD, particularly within the young adult population, are absent. AIM: To estimate the prevalence of ADHD amongst young adults attending university in UAE and examine its relationship with gender and academic outcomes. METHODS: A cross-sectional, correlational design was used. Young adults in their first year at university were recruited from different academic institutions across the UAE. The study utilized the Adult ADHD Self-Report Scale (ASRS) for data collection. RESULTS: A sample of 406 young adults, aged between 18 and 20 years of age were recruited. Approximately, 34.7% (n = 141) reported symptoms suggestive of probable ADHD. Significantly lower grade point average marks were observed in participants with ADHD symptoms (M = 3.15) compared to those without (M = 3.35). Females reported symptoms of probable ADHD at higher rates than males, indicating possibly a potential screening deficiency and a potential stigma consequence. CONCLUSIONS: The study demonstrates a high prevalence of probable ADHD in young adults, particularly among females attending university in the United Arab Emirates. Implications for early screening, service provision, and greater professional health training on this disorder are required.
