An outbreak of measles due to secondary vaccine failure prompted this investigation into the prevalence of measles antibody in children. We studied 608 children in 7 different age groups:6, 9, 14 and 18 months and 6, 10 and 15 years. Children in the 2 youngest groups received no vaccination; the rest were vaccinated at 9 months and 15 months. The 15-year-old age group received an additional vaccination. Transplacental measles antibody [Ab] decreased from 10.0% at 6 months to 0% at 9 months. Measles Ab was positive in 52.9% [14 months], 89.4% [18 months], 60.8% 96 years], 45.0% [10 years] and 96.8% [15 years]. To increase Ab levels, a booster vaccination is recommended, administered either with the second DPT booster or at pre-high school age

The article highlights and reveals the features of the technology of pedagogic support of individual educational activities of pupils in different age groups, the main of which is that the object of support is not only the individual educational activity of the pupil, but also the development of educational interaction of children of different ages, which causes the simultaneous use of two groups of principles: the principles of support of individual educational activities of pupils and the principles of development of educational interaction of children of different ages. The article reveals the tasks of pedagogic support of individual educational activities of children of different age groups studying in different age groups (7-11 years – primary school age; 12-16 years – adolescence; 17-18 years – early youth). Pedagogic support of individual educational activities of pupils in different age groups is considered as a subject-oriented technology of individualisation of the educational process and includes the following stages: diagnostic, design, practical and reflexive-analytical. In conclusion, the article draws conclusions about the state of the problem and the ways of its development.

Objective: To describe case rates, testing rates, and percent positivity of coronavirus disease 2019 (COVID-19) among children aged 0-18 years by school-age grouping. Design: We abstracted data from Georgia's State Electronic Notifiable Disease Surveillance System on all 10,437 laboratory-confirmed COVID-19 cases among children aged 0-18 years during March 30, 2020 to June 6, 2021. We examined case rates, testing rates, and percent positivity by school-aged groupings, namely: preschool (0-4 years), elementary school (5-10 years), middle school (11-13 years), and high school (14-18 years) and compared these data among school aged children to those in the adult population (19 years and older). Setting: Fulton County, Georgia. Main outcome measures: COVID-19 case rates, testing rates, and percent positivity. Results: Over time, the proportion of pediatric cases rose substantially from 1.1% (April 2020) to 21.6% (April 2021) of all cases in the county. Age-specific case rates and test rates were consistently highest among high-school aged children. Test positivity was similar across school-age groups, with periods of higher positivity among high-school aged children. Conclusions: Low COVID-19 testing rates among children, especially early in the pandemic, likely underestimate the true burden of disease in this age group. Despite children having lower measured incidence of COVID-19, we found when broader community incidence increased, incidence also increased among all pediatric age groups. As the COVID-19 pandemic continues to evolve, it remains critical to continue learning about the incidence and transmissibility of COVID-19 in children.

Abstract Background Since the announcement of COVID-19 as a pandemic infection, several studies have been performed to discuss the clinical picture, laboratory finding, and imaging features of this disease. The aim of this study is to demarcate the imaging features of novel coronavirus infected pneumonia (NCIP) in different age groups and outline the relation between radiological aspect, including CT severity, and clinical aspect, including age, oxygen saturation, and fatal outcome. We implemented a prospective observational study enrolled 299 laboratory-confirmed COVID-19 patients (169 males and 130 females; age range = 2–91 years; mean age = 38.4 ± 17.2). All patients were submitted to chest CT with multi-planar reconstruction. The imaging features of NCIP in different age groups were described. The relations between CT severity and age, oxygen saturation, and fatal outcome were evaluated. Results The most predominant CT features were bilateral (75.4%), posterior (66.3%), pleural-based (93.5%), lower lobe involvement (89.8%), and ground-glass opacity (94.7%). ROC curve analysis revealed that the optimal cutoff age that was highly exposed to moderate and severe stages of NCIP was 38 years old (AUC = 0.77, p < 0.001). NCIP was noted in 42.6% below 40-year-old age group compared to 84% above 40-year-old age group. The CT severity was significantly related to age and fatal outcome (p < 0.001). Anterior, centrilobular, hilar, apical, and middle lobe involvements had a significant relation to below 90% oxygen saturation. A significant negative correlation was found between CT severity and oxygen saturation (r = − 0.49, p < 0.001). Crazy-paving pattern, anterior aspect, hilar, centrilobular involvement, and moderate and severe stages had a statistically significant relation to higher mortality. Conclusion The current study confirmed the value of CT as a prognostic predictor in NCIP through demonstration of the strong relation between CT severity and age, oxygen saturation, and the fatal outcome. In the era of COVID-19 pandemic, this study is considered to be an extension to other studies discussing chest CT features of COVID-19 in different age groups with demarcation of the relation of chest CT severity to different pattern and distribution of NCIP, age, oxygen saturation, and mortality rate.

Background/Aims: To examine the influence of age on neuropsychological performances in dementia with Lewy bodies (DLB) and Alzheimer disease (AD) patients. Methods: We examined memory, executive, and visuo-constructional performances in 202 DLB patients and 236 AD patients. We divided the subjects into three age groups (65–74, 75–84, and 85–95 years old), and evaluated the differences in neuropsychological performances. Results: Recent memory in the DLB group was significantly better than that in the age-matched AD group when comparing the age groups 65–74 years and 75–84 years; however, memory impairment in the DLB patients in the age group 85–95 years was comparable with that in the age-matched AD patients. In contrast to recent memory, the other assessed neuropsychological performances, such as visuospatial and executive functions, showed no significant change in differences between the DLB and AD groups with advancing age. Conclusion: Our study revealed that the nature of memory impairment in DLB patients changes according to age. DLB patients in the young-old and old-old age groups showed significantly better memory performance than the age-matched AD patients, whereas memory performance of the DLB patients in the oldest-old age group was similar to that of the age-matched AD patients. This may be associated with the increased rate of coexisting AD pathology in DLB patients with older age.

This study aims to analyze mental health and anxiety levels during the COVID-19 pandemic. This study focused on students who were forced to study at home by e-learning. This study used as many as 210 students from junior high school, senior high school, and university levels which were selected randomly. Then, this study used a mixed-method by combining quantitative and qualitative approaches. Multivariate analysis of variance (MANOVA) was used to obtain empirical results to compare mental health and anxiety levels based on student age groups. The analysis results revealed there was a positive and significant influence of the students’ age group on mental health and anxiety levels during the outbreak of COVID-19. The analysis also concluded that students in the 12-15 years’ age group had the worst mental health level. Meanwhile, students in the 20-25 years’ age group are known to have the lowest anxiety level. Overall, this study found that Indonesian students experienced a decline in mental health and detected an increase in anxiety levels. The level of mental health and student anxiety has implications for their learning at home, which can lead to unsatisfactory learning outcomes.

Abstract Background Kano state has been a protracted reservoir of poliovirus in Nigeria. Immunity trends have been monitored through seroprevalence surveys since 2011. The survey in 2015 was, in addition, intended to assess the impact of use of inactivated poliovirus vaccine (IPV). Methods It was a health facility based seroprevalence survey. Eligible children aged 6-9, 12-15 and 19-22 months of age brought to the paediatrics outpatient department of Murtala Mohammad Specialist Hospital between 19 October and 6 November 2015, were screened for eligibility. Eligible children were enrolled after parental consent, history taken, physical examination conducted, and a blood sample collected to test for neutralizing antibody titres against the three poliovirus serotypes. Results Overall, 365 results were available in the three age groups. In the 6-9-month-old age group, the seroprevalence was 73% (95% confidence interval [CI] 64-80%), 83% (95% CI 75-88%), and 66% (95% CI 57-73%) for serotypes 1, 2, and 3, respectively. In the 12-15- and 19-22-month-old age groups, seroprevalence was higher but still remained <90% across serotypes. Seroprevalence to serotypes 1 and 3 in 2015 was similar to 2014; however, for serotype 2 there was a significant improvement. IPV received in supplemental immunization activities was found to be a significant predictor of seropositivity among 6-9-month-old infants for serotypes 1 and 2. Conclusions Seroprevalence for serotypes 1 and 3 remains low (<80%) in 6-9-month-olds. This poses a significant risk for poliovirus spread if reintroduced into the population. Efforts to strengthen immunization coverage are imperative to secure and sustain high population immunity.

Abstract Purpose Despite considerable research on pediatric sports-related concussion (SRC), few studies have analyzed groups from school-age through young adulthood. This study aimed to examine acute symptoms (i.e., emotional, physical, and cognitive) and recovery times across this age range. Methods Participants age 5–25 with SRC (n=611) presented to concussion clinics in the North Texas Concussion Registry within 2 weeks of injury. Subjects were stratified into 4 age groups: early elementary (age 5-9; n=19), late elementary (10–13; n=181), high school (14-17; n=384), and college (18-25; n=39). The Patient Health Questionnaire-9 (PHQ-9), General Anxiety Disorder-7 Item Scale (GAD-7), and concussion symptom log (Sx log), were administered. ANOVA was used to compare symptom scores and recovery times across groups. Results Differences were found on PHQ-9 scores (p=.05), with the early elementary and high school groups reporting significantly higher levels of depressive symptoms than the late elementary and college groups. No differences were seen on GAD-7 scores. Differences in Sx log severity scores were nonsignificant (p=.09), although scores increased with age (early: M=21.4, late=25.7, high school=30.0, college=35.5). Lastly, recovery time differed across groups (p=.008), with early elementary participants having the longest recovery (M=8.3 days) and the college group having the shortest (M=5.1 days). Conclusion Older age groups reported higher levels of acute post-concussion symptoms and more rapid recovery compared to younger age groups, suggesting that symptomatology and recovery time vary developmentally and the effects of age warrant consideration in young athletes.

Background Recently an association was demonstrated between the single nucleotide polymorphism (SNP), rs1042725, within the HMGA2 locus and height as a consequence of a genome wide association (GWA) study of this trait in adults; this observation was also reported in children aged 7–11 years old. Objective We examined in our Caucasian childhood cohort the effects of two strong surrogates for this SNP at this locus with height, rs8756 and rs7968902, with respect to the same pediatric age category but also in children grouped separately as younger and older. Methods Utilizing data from an ongoing GWA study in our cohort of 2,619 Caucasian children with measurements for height, we investigated the association of the previously reported variation at the HMGA2 locus with this height treated as a quantitative trait (age and sex corrected) in childhood in the 2–6 (n = 706), 7–11 (n = 617) and 12–18 (n = 1293) years old categories. Results The minor alleles of rs8756 and rs7968902 respectively (strong surrogates for rs1042725 i.e. r 2 = 0.873 and 0.761 in the CEU HapMap respectively) were significantly associated with height in the 7–11 years old age group ( P = 3.53 × 10–3 and 2.82 × 10–4, respectively) However in the 2–6 and 12–18 years old age groups, no association was observed. Conclusions We observe a strong association with height in same age group of 7–11 years old as has been previously reported. However, in the under 7s and the over 11s, no such association was observed.

AbstractPertussis is a vaccine-preventable disease and antibodies formed are known to decline with time. The aim of this study was to measure Bordetella pertussis/toxin immunoglobulin G (IgG) antibodies in different age groups of Nigerian children and determine the age at which booster dose may be required. A total of 422 children, aged 6 to 60 months, were tested for the presence of B. pertussis/toxin IgG antibodies by ELISA (enzyme-linked immune sorbent assay). The highest positivity rate was in the 6 to 11 months of age group, while the highest negativity rate was in the age group of 24 to 35 months. We conclude that B. Pertussis/toxin IgG antibodies response is weak in Nigerian children after three doses of DPT (diphtheria, pertussis, and tetanus)/pentavalent vaccination, and there is a rapid decline of antibody levels between 12 and 35 months. We recommend that booster vaccination should be given at 12 to 15 months of age.
