MicroRNA-29-mediated cross-talk between metabolic organs in the pathogenesis of diabetes mellitus and its complications: A narrative review.

Diabetes mellitus (DM) is a heterogeneous group of disorders characterized by hyperglycemia. Microribonucleic acids (microRNAs) are noncoding RNA molecules synthesized in the nucleus, modified, and exported to the extracellular environment to bind to their complementary target sequences. It regulates protein synthesis in the targeted cells by inhibiting translation or triggering the degradation of the target messenger. MicroRNA-29 is one of noncoding RNA that can be secreted by adipose tissue, hepatocytes, islet cells, and brain cells. The expression level of the microRNA-29 family in several metabolic organs is regulated by body weight, blood concentrations of inflammatory mediators, serum glucose levels, and smoking habits. Several experimental studies have demonstrated the effect of microRNA-29 on the expression of target genes involved in glucose metabolism, insulin synthesis and secretion, islet cell survival, and proliferation. These findings shed new light on the role of microRNA-29 in the pathogenesis of diabetes and its complications, which plays a vital role in developing appropriate therapies. Different molecular pathways have been proposed to explain how microRNA-29 promotes the development of diabetes and its complications. However, to the best of our knowledge, no published review article has summarized the molecular mechanism of microRNA-29-mediated initiation of DM and its complications. Therefore, this narrative review aims to summarize the role of microRNA-29-mediated cross-talk between metabolic organs in the pathogenesis of diabetes and its complications.

Utilization of cervical cancer screening and determinant factors among female nurses in selected public hospitals in Addis Ababa, Ethiopia.

BACKGROUND: Cervical cancer is one of the top cause of death among childbearing women globally and public health issue for underdeveloped nations.It is the world's second most prevalent cancer among women. In 2018, 311,000 women died due to cervical cancer.Approximately 80 % of these deaths occurred in developing countries.However, there has been insufficient research on cervical cancer screening utilisation among Ethiopian nurses, despite the fact that nurses promote women's health and play a key role in cervical cancer education. As a result, evaluating utilization of cervical cancer screening among nurses is critical for program effectiveness. OBJECTIVE: To assess the magnitude of utilization of cervical cancer screening and determinant factors among female Nurses in selected public hospitals in Addis Ababa, Ethiopia. METHODOLOGY: An institutional-based cross-sectional study design was employed from October 1 to November 30, 2022. Data was collected using an interviewer-administered questionnaire. The data was entered into Epi data version 3.1 and then exported to SPSS version 22 for data management and analysis. Bivariate and multi-variable logistic regressions were employed to identify the predictor variables. Statistical significance was considered at P < 0.05 with adjusted odds ratio calculated at 95 % CI. RESULT: The magnitude of utilization of cervical cancer screening among nurses working in selected public hospitals in Addis Ababa was 18.5 % (95 % CI: 14.2, 23.1). Having work experience > 8 years (AOR = 16.78; 95 % CI: 4.82, 58.44), history of STI (AOR = 53.72; 95 % CI: 14.18, 203.45) and having multiple sexual partners (AOR = 12.74; 95 % CI: 4.15, 39.11) were significantly associated with utilization of cervical cancer screening among female nurses. CONCLUSION: The overall cervical cancer screening rate among female nurses was low compared to the WHO strategy for cervical cancer elimination, which asks for 70 % of women worldwide to be checked for cervical illnesses regularly by 2030. According to the study findings, respondents' work experience, STI history, and having multiple sexual partners influenced their utilization of cervical cancer screening among nurses. To boost the utilization of screening services, female nurses should place a strong emphasis on maintaining screening awareness through education and knowledge sharing.Finally, we recommend future researchers to do comparative study design to draw any scientific and credible conclusions.
