A reverse pattern in work motivation among Vietnamese health care workers during the prolonged COVID-19 outbreak of 2021: Determinants and implications.

Background: The workload burden of the COVID-19 pandemic on health systems requires not only financial support but also long-term and contextualized policies. We assessed the work motivation and its determinants among health workers at Vietnamese hospitals and facilities during the prolonged COVID-19 outbreaks in 2021. Methods: A cross-sectional study was conducted among 2814 health care professionals across all three regions of Vietnam from October to November 2021. An online questionnaire, including the Work Motivation Scale, distributed by the snowball method to a subgroup of 939 respondents, investigated changes in working characteristics due to COVID-19, work motivation, and occupational intention. Results: Only 37.2% of respondents committed to their current job and about 40% reported a decrease in their job satisfaction. The Work Motivation Scale scored the lowest in "financial motivation" and the highest in "perception of work value". Participants who were in the north region, of younger age, unmarried, and who had a low level of adaptability to external work pressure, shorter experience, and less job satisfaction tended to be less motivated and committed to their current job. Conclusions: Intrinsic motivation has increased in importance during the pandemic. Therefore, policymakers should develop interventions that raise intrinsic, psychological motivation instead of only focusing on salary raises. Issues about intrinsic motivations of health care workers such as low adaptability to stress and professionalism in routine work should be prioritized during the pandemic preparedness and control.

SRSF7 and SRSF3 depend on RNA sequencing motifs and secondary structures to regulate Microprocessor.

Human Microprocessor cleaves pri-miRNAs to initiate miRNA biogenesis. The accuracy and efficiency of Microprocessor cleavage ensure appropriate miRNA sequence and expression and thus its proper gene regulation. However, Microprocessor cleaves many pri-miRNAs incorrectly, so it requires assistance from many cofactors. For example, SRSF3 enhances Microprocessor cleavage by interacting with the CNNC motif in pri-miRNAs. However, whether SRSF3 can function with other motifs and/or requires the motifs in a certain secondary structure is unknown. In addition, the function of SRSF7 (a paralog of SRSF3) in miRNA biogenesis still needs to be discovered. Here, we demonstrated that SRSF7 could stimulate Microprocessor cleavage. In addition, by conducting high-throughput pri-miRNA cleavage assays for Microprocessor and SRSF7 or SRSF3, we demonstrated that SRSF7 and SRSF3 function with the CRC and CNNC motifs, adopting certain secondary structures. In addition, SRSF7 and SRSF3 affect the Microprocessor cleavage sites in human cells. Our findings demonstrate the roles of SRSF7 in miRNA biogenesis and provide a comprehensive view of the molecular mechanism of SRSF7 and SRSF3 in enhancing Microprocessor cleavage.

Social Media Addiction among Vietnam Youths: Patterns and Correlated Factors.

BACKGROUND: Prior research has investigated how the excessive use of social media has an impact on one's functioning. Youths are among the most vulnerable subjects to the impacts of social media overuse, especially in Vietnam (a developing country). However, very little evidence has been provided on social media addiction. This work aims to determine the prevalence of social media addiction amongst Vietnamese individuals and the factors associated with social media addiction. METHOD: An online cross-sectional study was conducted from June to July 2020 in Vietnam. Participants completed the structured questionnaire, which comprised four main components: (1) social characteristics; (2) The Bergen Social Media Addiction Scale; (3) stress associated with neglect and negative reactions by online peers and fear of missing out (FOMO); and (4) status of social media platform usage. RESULTS: Some demographic factors, such as gender, the locality of accommodation, and relationship status affected the overall scores. The results also indicated Facebook, Zalo, and Youtube to be the most popular social media platforms among Vietnamese youths. Individuals who used social media for gaming also had higher BSMAS scores. FOMO and stress associated with neglect by online peers had a high correlation with social media addiction. CONCLUSIONS: This study is one of the first studies to examine social media addiction and its associated factors in Vietnam. Interventions for social media addiction need to be developed in different fields: clinical research, policy, and education.

Determinants of mental health among youths and adolescents in the digital era: Roles of cyber and traditional bullying, violence, loneliness, and environment factors.

Introduction: Although the pathogenesis of depressive disorders is not fully elucidated, untreated adolescent depression can lead to serious sequelae such as impaired academic performance and social functioning, substance use disorders, poor self-esteem, and increased risk for suicidal ideation and attempts. Literature on adolescent mental health in Vietnam is limited, despite increased international awareness of this critical issue. This study aimed to investigate the prevalence and associations of depressive symptoms in Vietnamese adolescents. Methods: A cross-sectional, self-administered survey was conducted in five provinces of Vietnam among adolescents aged 14 to 24 years. In addition to collecting participants' demographics, a structured questionnaire was developed to examine depressive symptoms, suicidal ideation, loneliness, and cyberbullying victimization. Depressive symptoms and loneliness were assessed via the PHQ-9 and UCLA Loneliness Scale, respectively. Two-tailed Chi-squared, Mann-Whitney, and Kruskal-Wallis tests were performed to examine associations between variables. Multivariate Logistic regression models were conducted to examine the associations between prior-defined variables and positive depressive symptoms. Results: Among 1,600 respondents, 31.8% of participants reported having mild-moderate or severe depressive symptoms. Participants within the moderate-severe depressive symptom group had significantly lower community cohesion scores than those of participants in normal and mild depressive symptom groups (p < 0.05). Youths living alone were more likely to have moderate-severe depressive symptoms (OR 2.16; 95% CI: 1.09-4.25). Cyberbullying had significant associations with depressive severity (OR 1.93; 95% CI 1.38-2.70). Conclusion: The findings of this study characterize various risk and protective factors for depression in Vietnamese youths and adolescents. The results highlight the importance of raising awareness and increasing access to educational resources for depression and other mental health illnesses. With the rising prevalence of depression, parents, teachers, and community leaders play a vital role in addressing mental health problems in adolescents.

Intramolecular ligation method (iLIME) for pre-miRNA quantification and sequencing.

Hairpin-containing pre-miRNAs, produced from pri-miRNAs, are precursors of miRNAs (microRNAs) that play essential roles in gene expression and various human diseases. Current qPCR-based methods used to quantify pre-miRNAs are not effective to discriminate between pre-miRNAs and their parental pri-miRNAs. Here, we developed the intramolecular ligation method (iLIME) to quantify and sequence pre-miRNAs specifically. This method utilizes T4 RNA ligase 1 to convert pre-miRNAs into circularized RNAs, allowing us to design PCR primers to quantify pre-miRNAs, but not their parental pri-miRNAs. In addition, the iLIME also enables us to sequence the ends of pre-miRNAs using next-generation sequencing. Therefore, this method offers a simple and effective way to quantify and sequence pre-miRNAs, so it will be highly beneficial for investigating pre-miRNAs when addressing research questions and medical applications.

Select amino acids in DGCR8 are essential for the UGU-pri-miRNA interaction and processing.

Microprocessor, composed of DROSHA and DGCR8, processes primary microRNAs (pri-miRNAs) in miRNA biogenesis. Its cleavage efficiency and accuracy are enhanced because DGCR8 interacts with the apical UGU motif of pri-miRNAs. However, the mechanism and influence of DGCR8-UGU interaction on cellular miRNA expression are still elusive. In this study, we demonstrated that Rhed (i.e., the RNA-binding heme domain, amino acids 285-478) of DGCR8 interacts with UGU. In addition, we identified three amino acids 461-463 in Rhed, which are critical for the UGU interaction and essential for Microprocessor to accurately and efficiently process UGU-pri-miRNAs in vitro and UGU-miRNA expression in human cells. Furthermore, we found that within the DGCR8 dimer, the amino acids 461-463 from one monomer are capable of discriminating between UGU- and noUGU-pri-miRNAs. Our findings improve the current understanding of the substrate-recognizing mechanism of DGCR8 and implicate the roles of this recognition in differentiating miRNA expression in human cells.
