Assessment of descending aortic blood flow velocities with continuous wave Doppler echocardiography among healthy Children in South East Nigeria.

Background: The descending aorta velocity is important predictor of aortic disease in children and can be very helpful in some clinical and surgical decision making. Aim: The purpose of this study is to assess the normative values of descending aorta velocity among children from South-East Nigeria. It also aimed to assess the correlation between age, body surface area and mean velocity across the descending aorta. Methods: This is a cross-sectional study where the descending aorta velocity of one hundred and eleven children were enrolled consecutively using digitized two-dimensional and Doppler echocardiography. Results: A total of 111 children had echocardiography to study their cardiac structures and compute their mean scores of their descending aorta velocity. The mean velocity across the descending aorta was 1.3±0.2m/s with maximum and minimum velocities of 2.06 and 0.84cm respectively. The mean descending aorta velocity in males (1.37±0.24 m/s) was significantly higher than that in females (1.24±0.18); (Student T test 3.09, p = 0.03). There was no correlation between age and mean velocity across the descending aorta (Pearson correlation coefficient; -0.03, p = 0.7) nor between body surface area and descending aorta velocity (correlation coefficient 0.01, p= 0.8). Conclusions: The presented normalized values of the descending aorta velocity using a digitized two-dimensional and Doppler echocardiography among healthy children will serve as a reference values for further studies and can be applied for clinical and surgical use in children with various cardiac anomalies.

Willingness to accept malaria vaccines amongst women presenting at outpatient and immunization clinics in Enugu state, Southeast Nigeria.

BACKGROUND: There are giant steps taken in the introduction of the novel malaria vaccine poised towards reducing mortality and morbidity associated with malaria. OBJECTIVES: This study aimed to determine the knowledge of malaria vaccine and factors militating against willingness to accept the vaccine among mothers presenting in nine hospitals in Enugu metropolis. METHODS: This was a cross-sectional study carried out among 491 mothers who presented with their children in nine hospitals in Enugu metropolis, South-East Nigeria. A pre-tested and interviewer-administered questionnaire was used in this study. RESULTS: A majority of the respondents, 72.1% were aware of malaria vaccine. A majority of the respondents, 83.1% were willing to receive malaria vaccine. Similarly, a majority of the mothers, 92.9%, were willing to vaccinate baby with the malaria vaccine, while 81.1% were willing to vaccinate self and baby with the malaria vaccine. The subjects who belong to the low socio-economic class were five times less likely to vaccinate self and baby with malaria vaccine when compared with those who were in the high socio-economic class (AOR = 0.2, 95% CI 0.1-0.5). Mothers who had good knowledge of malaria vaccination were 3.3 times more likely to vaccinate self and baby with malaria vaccine when compared with those who had poor knowledge of malaria vaccination (AOR = 3.3, 95% CI 1-6-6.8). CONCLUSION: Although the study documented a high vaccine acceptance among the mothers, there exists a poor knowledge of the malaria vaccine among them.

The unique contributions of depression and anxiety to suicidal ideation among Nigerian secondary school students: a cross-sectional survey.

Background: It is important to establish the pattern of suicidal ideation among adolescents with depression and anxiety. This will help the schools prevent possible complete suicide among these groups of adolescents' trough counseling and education. Objectives: This work is therefore aimed at determining the effects of depression and anxiety on adolescent suicide ideation and factors that predict suicidal ideation among adolescents attending secondary school in southeast Nigeria. Methods: A cross-sectional study among 450 secondary school adolescents in Enugu state, Nigeria. Information was obtained using the Columbia suicide severity rating scale and the Hospital Anxiety and Depression Scale (HADS). Chi-square test, correlation analysis and Hierarchical logistic regression were used in the analysis, and the level of statistical significance was determined using a P-value of <0.05. Results: The prevalence of anxiety was 36.4% while that of depression was 30.7%. The prevalence of suicidal ideation was 8.4%. The prevalence of suicidal ideation among adolescents who were <15 years was 8.0% while those who were between 15 - 18 years was 13.5% and those more than 19 years of age was 22.5%. The prevalence of suicidal ideation among adolescents with depression is 21.7% and 78.3 % for those without depression while the prevalence of suicidal ideation among adolescents with anxiety is 20.1% and 79.9 % for those without anxiety. The prevalence of suicidal ideation among the poorest half was 16.4% and 10.2% in the richer half. There was a higher prevalence of suicidal ideation among the urban dwellers (53.3%) than the rural dwellers (46.7%).There was a positive correlation between suicide and age in years and this was found to be statistically significant, (n=450, r=0.107, p=0.023). A significantly higher proportion of respondents who had depression, 21.7% had suicidal ideation when compared with those who were not, (χ 2=12.170, p<0.001). Similarly, a significantly higher proportion of respondents who had an anxiety disorder, (20.1%) had suicidal ideation when compared with those who were not, 9.4%, (χ 2=10.291, p=0.001). The respondents who were 19 years and above had increased suicidal ideation, and the difference in proportions was found to be statistically significant, (χ 2=6.440, p=0.040). A significantly higher proportion of females, 16.6% had suicidal intentions when compared with the males, 7.1%, (χ 2=7.958, p=0.005). Conclusion: There is an increasing prevalence of suicidal ideation among adolescents with a preponderance of older age and female gender. There is a link between depression/anxiety and suicidal ideation. The prevalence of suicidal ideation among the poorest half was higher than that of the richer half. There was a higher prevalence of suicidal ideation among the urban dwellers than the rural dwellers.

Problem gambling among secondary school adolescents in Enugu, Nigeria.

Background: Adolescent problem gambling is a common behavioural issue and could be associated with internet addiction. Objectives: To determine the pattern of problem gambling and factors that predict gambling among adolescents that attended secondary schools in southeast Nigeria. Methodology: This is a cross-sectional study design. A three-stage sampling technique was used to select 796 secondary school adolescents from eight secondary schools in Enugu State, Nigeria. Results: The highest proportion of the respondents, 38.3% had problem gambling with negative consequences. There was a weak positive correlation between gambling severity index and internet addiction. (n=796, r=0.254, p<0.001). There is a very weak negative correlation between gambling severity index and age in years. (n=796, r= -0.034, p=0.331).The male respondents were 1.5 times more likely to have problem gambling when compared with the females, (AOR=1.5; (95%CI: 1.1-2.0). The respondents who have internet addiction were 3.5 times more likely to have problem gambling when compared with those who do not have an internet addiction, (AOR=3.5; 95%CI: 2.6-4.8). Conclusion: The prevalence of gambling among adolescents is high. Adolescents who had problem gambling also had internet addiction. The male respondents were more likely to have problem gambling than their female folk.

Willingness of college students aged 10 to 24 years to get vaccinated against COVID-19 disease: a cross-sectional study in South-East Nigeria.

Background: Willingness to be vaccinated against COVID-19 is a topical issue that may change the course and distribution of the pandemic in the country. Objectives: This study was aimed to determine the willingness to receive the COVID-19 vaccine among college adolescents and associated factors. Methodology: This was a cross-sectional study carried out among one thousand college adolescents in six secondary schools in Enugu from April to August 2021. A pretested, self-administered questionnaire was used for data collection. Data entry and analysis were done using IBM Statistical Package for Social Sciences (SPSS) statistical software version 25. Descriptive statistics were used to describe college adolescents' characteristics. Categorical variables were reported as frequencies and percentages. Predictors of willingness to vaccinate were assessed using binary logistic regression. Results: A minor proportion of the respondents, 13.2% (153) were willing to receive the COVID-19 vaccine. The respondents who were males were 1.6 times more willing to receive the COVID-19 vaccination when compared with those who were females. (AOR=1.6, 95%CI: 1.1- 2.3). The respondents who were aware they could be infected with COVID-19 were twice more likely to receive COVID-19 vaccination when compared with those who felt they could not be infected. (AOR=2.0, 95%CI: 1.1-3.1). The respondents who had good knowledge of COVID-19 vaccination were 2.2 times more likely to receive COVID-19 vaccination when compared with those who had poor knowledge. (AOR=2.2, 955CI: 1.5-3.3). Conclusion: A small fraction of college adolescents were willing to receive the COVID-19 vaccine. Male gender, knowledge of vaccine and possibility of transmitting infection are predictors of willingness to receive the vaccination.
