METHOD: By using the keywords "acute lymphoblastic leukemia", and "microarray", a total of 280 and 275 microarray datasets were found listed in Gene Expression Omnibus database GEO and ArrayExpress database respectively. Further manual inspection found that only three studies (GSE18497, GSE28460, GSE3910) were focused on gene expression profiling of paired diagnosis-relapsed pediatric B-ALL. These three datasets which comprised of a total of 108 matched diagnosis-relapsed pediatric B-ALL samples were then included for this meta-analysis using RankProd approach.
RESULTS: Our analysis identified a total of 1795 upregulated probes which corresponded to 1527 genes (pfp 1), and 1493 downregulated probes which corresponded to 1214 genes (pfp
MATERIALS AND METHODS: Whole genome sequencing was performed on matched samples collected at diagnosis, remission and relapse from three patients of de novo childhood AML. Sanger sequencing was performed for validation in 47 patients' samples, followed by functional analysis.
RESULTS: Overall, we identified 312 somatic mutations including synonymous single nucleotide variants (SNVs), missense SNVs, deletions and insertion frameshifts, stopgains and splice sites. After prioritisation, only 46 variants were present at diagnosis (13-17 mutations per patient) and 49 variants at relapse (12-20 mutations per patient). Out of 81 variants, there were 35 new variants detected at relapse but not present at diagnosis. Six potential driver mutations (KIT, CDC73, HNF1A, RBM10, ZMYM4 and ETV6) were identified in predicting relapse for the 3 patients, with recurrent mutations of the ETV6 gene in 2 patients. Functional analysis of the ETV6 mutation showed that ETV6 lost its tumour suppressive function when both mutant ETV6 p.P25fs and ETV6 p.N75fs were tested in vitro.
CONCLUSION: This study has uncovered the mutational landscape in three local childhood AML patients and contributes to a better understanding of the molecular mechanisms of relapsed AML.
METHODS: A cross-sectional population survey using an online questionnaire commenced on 14 February 2020. The study participants were residents of Taiwan ages 20 to 70 years. The 6-item state version of the State-Trait Anxiety Inventory (STAI-6) was used to assess anxiety symptoms. The questions about preventive measures asked participants about their personal protection, cough etiquette, contact precautions, voluntary quarantine, and prompt reporting. Multivariable logistic regression was used to determine the factors influencing an increase in the preventive measures scores.
RESULTS: Of a total of 3555 completed responses, a total of 52.1% (95% confidence interval [CI] 50.4-53.7) of the respondents reported moderate to severe levels of anxiety symptoms in the past week, whereas 48.8% (95%CI 47.2-50.5) reported moderate to severe anxiety symptoms at the beginning of the outbreak. With a higher score indicating greater anxiety, the median scores for anxiety symptoms in the past week and at the beginning of the outbreak were 46.7 (IQR [interquartile range] 36.7-53.3) and 43.3 (IQR 36.7-53.3), respectively. The median scores for the preventive measures taken in the past week and at the beginning of the outbreak were 26.0 (IQR 21.0-30.0) and 24.0 (IQR 19.0-28.0), respectively, out of a maximum score of 36. In the multivariable analysis, an increased anxiety symptom score from the beginning of the outbreak to the past week (adjusted OR = 7.38, 95%CI 6.28-8.66) was a strongly significant determinant of an increased preventive measures score in the past week compared with the score at the beginning of the outbreak.
CONCLUSIONS: Anxiety and preventive measures scores were high and increased with the epidemic rate. Higher anxiety was associated with an increased use of preventive measures against COVID-19.
Methods: A cross-sectional, self-administered online survey was carried out between 3 September and 15 October 2020.
Results: A total of 8393 complete responses were received from a nationwide sample. Poor sustainability in the practice of "new norm" was reported. Noteworthy disparities were observed in willingness to carry out "new normal" practices by gender, urban-rural locality, non-Han and Han Chinese and educational attainment. There was evidence of economic and social disruption associated with COVID-19 or "new normal" practices. The current mean (±standard deviation [SD]) happiness score (110.45 ± 17.55) was slightly lower than the mean happiness score before (111.12 ± 17.83) the COVID-19 pandemic (t= -9.01, p<0.001). Lower socioeconomic status and greater economic and social disruptions were associated with lower current happiness scores. Moreover, greater willingness to adapt to "new normal" practices was associated with higher levels of happiness.
Conclusion: There is a need to encourage sustainable practice of new norm post-pandemic. Segments of the public continue to experience significant economic and social effects and the post-pandemic 'new norms' remain at risk of leading to psychological consequences.
METHODS: A cross-sectional survey was conducted from 3 to 12 April 2020. The health belief model (HBM) was used to assess predictors of the intent to receive the vaccine and the WTP.
RESULTS: A total of 1,159 complete responses was received. The majority reported a definite intent to receive the vaccine (48.2%), followed by a probable intent (29.8%) and a possible intent (16.3%). Both items under the perceived benefits construct in the HBM, namely believe the vaccination decreases the chance of infection (OR = 2.51, 95% CI 1.19-5.26) and the vaccination makes them feel less worry (OR = 2.19, 95% CI 1.03-4.65), were found to have the highest significant odds of a definite intention to take the vaccine. The mean ± standard deviation (SD) for the amount that participants were willing to pay for a dose of COVID-19 vaccine was MYR$134.0 (SD±79.2) [US$30.66 ± 18.12]. Most of the participants were willing to pay an amount of MYR$100 [US$23] (28.9%) and MYR$50 [US$11.5] (27.2%) for the vaccine. The higher marginal WTP for the vaccine was influenced by no affordability barriers as well as by socio-economic factors, such as higher education levels, professional and managerial occupations and higher incomes.
CONCLUSIONS: The findings demonstrate the utility of HBM constructs in understanding COVID-19 vaccination intention and WTP.
METHODS: A online cross-sectional survey was conducted with the people living in Wuhan between March 12th and 23rd, 2020.
RESULTS: Of a total of 2411 complete responses, the mean and standard deviation for the total physical prevention barriers score was 19.73 (standard deviation ± 5.3; range 12-45) out of a possible score of 48. Using a cut-off score of 44 for the State-Trait Inventory score, 79.9% (95% confidence interval [CI]: 78.2-81.5) of the participants reported moderate to severe anxiety during the early phase of the outbreak, and 51.3% (95% CI 49.2-53.3) reported moderate to severe anxiety after the peak of coronavirus disease 2019 was over (during the study period). Comparing anxiety levels in the early phase of the outbreak and after the peak of the outbreak, 58.5% (95% CI 56.5-60.5) recorded a decreased anxiety. Females reported a higher likelihood of having decreased levels of anxiety than males (odds ratio = 1.78, 95% CI 1.48-2.14). Low negative attitudes score were associated with a higher decrease in anxiety (odds ratio = 1.59, 95% CI 1.33-1.89).
CONCLUSIONS: The attitudinal barriers to prevention of transmission of coronavirus disease 2019 are more prominent than physical prevention barriers after the peak of coronavirus disease 2019. High anxiety levels even after the peak warrant serious attention.
Methods: An online survey was sent to all registered undergraduate nursing students at Fujian Medical University, China. The partial least squares structural equation model (PLS-SEM) was used to investigate key factors influencing turnover intention.
Results: A total of 1020 complete responses were received (response rate: 86.2%). Nearly half (49.1%) reported that they would choose not to be on a nursing course if given a choice, 45.4% often think of not going into the nursing profession in the future, and 23.7% would consider entering a healthcare industry that has zero contact with patients. The total turnover intention score range was 3 to 15, and the mean ± standard deviation (SD) was 9.2 (SD ± 2.5). PLS-SEM path analysis revealed that fear of COVID-19 (β = 0.226, p < 0.001) had a positive effect on turnover intention. Satisfaction with life (β = -0.212, p < 0.001) had a negative effect on turnover intention. Analysis of open-ended survey data on students' perspectives on how to encourage nursing students to enter the nursing workforce revealed five central themes: 1) professional role, respect, and recognition; 2) higher wages; 3) reduce workload; 4) enhance occupational health and safety; and 5) career advancement opportunities.
Conclusion: Factors influencing turnover intention and suggestions to reduce students' apprehension towards joining the nursing profession found in this study should be seriously taken into consideration in initiatives to address the nurse shortages.
DESIGN: A nationwide longitudinal survey.
SETTING: Thirty-two randomly selected schools from 13 states and 3 federal territories in Malaysia from February to March 2013, and October to November 2013.
PARTICIPANTS: Form One female students (13 years old).
INTERVENTIONS: None.
MAIN OUTCOME MEASURES: Mean knowledge score of HPV infection.
RESULTS: A total of 2644 students responded to the prevaccination survey, of whom 2005 (70%) completed the postvaccination survey. The mean knowledge score was 2.72 (SD ± 2.20) of a maximum score of 10 in the prevaccination survey, which increased significantly to 3.33 (SD ± 1.73) after the 3 doses of HPV vaccine (P = .001). Many answered incorrectly that, "Only girls can get HPV infection" (91.5%, n = 1841 prevaccination vs 96.1%, n = 1927 postvaccination), and only a few were aware that, "Vaccinating boys helps to protect girls against HPV infection" (11.4%, n = 229 for prevaccination vs 10.2%, n = 206 for postvaccination). The mean knowledge score was significantly higher postvaccination among higher-income families and those with parents of a higher occupational status. Regarding beliefs about the HPV vaccine, 89.4% in the prevaccination survey held the view that they would not get a HPV infection, and the percentage remained similar in the postvaccination survey. Perceived severity of HPV infection also remained low in the pre- and postintervention groups. Only 21.5% reported receiving health information about HPV along with the provision of the HPV vaccine; those who received health information showed higher levels of knowledge.
CONCLUSION: Findings revealed a general lack of knowledge and erroneous beliefs about HPV and the HPV vaccine even after receiving vaccination. This suggests that imparting accurate knowledge about HPV along with vaccine administration is essential. Specifically, girls from lower socioeconomic groups should be a target of educational intervention.
