Ontology highlight
ABSTRACT: Introduction
We used data from MOBI-Kids, a 14-country international collaborative case-control study of brain tumors (BTs), to study clinical characteristics of the tumors in older children (10 years or older), adolescents and young adults (up to the age of 24).Methods
Information from clinical records was obtained for 899 BT cases, including signs and symptoms, symptom onset, diagnosis date, tumor type and location.Results
Overall, 64% of all tumors were low-grade, 76% were neuroepithelial tumors and 62% gliomas. There were more males than females among neuroepithelial and embryonal tumor cases, but more females with meningeal tumors. The most frequent locations were cerebellum (22%) and frontal (16%) lobe. The most frequent symptom was headaches (60%), overall, as well as for gliomas, embryonal and 'non-neuroepithelial' tumors; it was convulsions/seizures for neuroepithelial tumors other than glioma, and visual signs and symptoms for meningiomas. A cluster analysis showed that headaches and nausea/vomiting was the only combination of symptoms that exceeded a cutoff of 50%, with a joint occurrence of 67%. Overall, the median time from first symptom to diagnosis was 1.42 months (IQR?0.53-4.80); it exceeded 1 year in 12% of cases, though no particular symptom was associated with exceptionally long or short delays.Conclusions
This is the largest clinical epidemiology study of BT in young people conducted so far. Many signs and symptoms were identified, dominated by headaches and nausea/vomiting. Diagnosis was generally rapid but in 12% diagnostic delay exceeded 1 year with none of the symptoms been associated with a distinctly long time until diagnosis.

Project description:PURPOSE:The burden of alcohol-attributable disease is a global problem. Young people often present to emergency health-care services with alcohol intoxication but little is known about how best to intervene at that point to improve future health outcomes. This study aimed to assess whether young people with an alcohol-specific hospital admission are at increased risk of injury following discharge. METHODS:A cohort study was conducted using a general population of 10- to 24-year-olds identified using primary care medical records with linked hospital admission records between 1998 and 2013. Exposed individuals had an alcohol-specific admission. Unexposed individuals did not and were frequency matched by age (±5 years) and general practice (ratio 10:1). Incidence rates of injury-related hospital admission post discharge were calculated, and hazard ratios (HR) were estimated by Cox regression. RESULTS:The cohort comprised 11,042 exposed and 110,656 unexposed individuals with 4,944 injury-related admissions during follow-up (2,092 in exposed). Injury rates were six times higher in those with a prior alcohol admission (73.92 per 1,000 person-years, 95% confidence interval (CI) 70.82-77.16 vs. 12.36, 11.91-12.81). The risk of an injury admission was highest in the month following an alcohol-specific admission (adjusted HR?=?15.62, 95% CI 14.08-17.34), and remained higher compared to those with no previous alcohol-specific admission at 1 year (HR 5.28 (95% CI 4.97-5.60)) and throughout follow-up. CONCLUSIONS:Young people with an alcohol-specific admission are at increased risk of subsequent injury requiring hospitalization, especially immediately post discharge, indicating a need for prompt intervention as soon as alcohol misuse behaviors are identified.

Project description:Background:Mental health disorders such as high levels of anxiety, isolation, depression and suicide ideation reported among young people living with HIV (10-24?years;YPLHIV) contribute significantly to poor medication adherence and retention in care. While there is evidence supporting the role of psychosocial support interventions in promoting adherence and retention in antiretroviral treatment (ART) among adults living with HIV, there is little evidence on the role of psychosocial support on medication adherence among YPLHIV. This scoping review was designed to identify and classify the types and effects of psychosocial support interventions designed to improve adherence and retention in ART among YPLHIV globally.Method:We searched six electronic databases (i.e., Scopus, Pubmed and EBSCOHost (Academic Search Premier, CINAHL, Psycarticles and Medline). Six relevant articles published between 2011 and 2019 met our inclusion criteria. We extracted information relevant to the nature and outcomes of the reported interventions using thematic content analysis informed by the Population, Intervention, comparison, outcome, and time (PICOT) framework.Results:Four distinctive treatment modalities that focused on improving ART adherence and retention in care were identified: individual counselling, support groups, family-centered services, and treatment supporters.Conclusion:There is a dearth of psychosocial support interventions to improve adherence and retention in ART amongst adolescents and young adults living with HIV. Future research and programming should seek to address psychosocial support interventions or approaches specifically designed to address the needs of YPLHIV.Trial registration:PROSPERO: Registration CRD42018105057 .

Project description:UNLABELLED: Preservation of limb function in pediatric oncology patients is challenging with the ongoing growth of limbs contralateral to reconstructed limbs. We analyzed 22 patients younger than 10 years old who received an allograft after resection of a bone sarcoma with a minimum followup of 2 years (mean, 4 years; range, 2-14 years). The mean age was 7 years (range, 2-10 years). There were 16 boys and six girls with 17 osteosarcomas and five Ewing's sarcomas. Thirteen reconstructions were performed with an intercalary allograft and nine with an osteoarticular allograft. Physes were uninvolved in five patients and one physis in 17. We documented outcomes using the Musculoskeletal Tumor Society functional and the International Society of Limb Salvage radiographic scoring systems. At last followup, three of the 22 patients died of their tumor, one was alive but with an amputation, and 18 retained their limbs. These 18 patients had an average functional score of 27 points and a mean radiographic score of 94%. Eight complications required a second surgery; in four, the allograft was removed (one infection, one local recurrence, two fractures) and in four, the allograft was preserved (two local recurrences, one fracture, one nonunion). We consider biologic reconstruction with allografts after sarcoma resection an appropriate reconstructive procedure in young children. LEVEL OF EVIDENCE: Level IV, therapeutic study.

Project description:Summary Background Documentation of patterns and long-term trends in mortality in young people, which reflect huge changes in demographic and social determinants of adolescent health, enables identification of global investment priorities for this age group. We aimed to analyse data on the number of deaths, years of life lost, and mortality rates by sex and age group in people aged 10–24 years in 204 countries and territories from 1950 to 2019 by use of estimates from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. Methods We report trends in estimated total numbers of deaths and mortality rate per 100 000 population in young people aged 10–24 years by age group (10–14 years, 15–19 years, and 20–24 years) and sex in 204 countries and territories between 1950 and 2019 for all causes, and between 1980 and 2019 by cause of death. We analyse variation in outcomes by region, age group, and sex, and compare annual rate of change in mortality in young people aged 10–24 years with that in children aged 0–9 years from 1990 to 2019. We then analyse the association between mortality in people aged 10–24 years and socioeconomic development using the GBD Socio-demographic Index (SDI), a composite measure based on average national educational attainment in people older than 15 years, total fertility rate in people younger than 25 years, and income per capita. We assess the association between SDI and all-cause mortality in 2019, and analyse the ratio of observed to expected mortality by SDI using the most recent available data release (2017). Findings In 2019 there were 1·49 million deaths (95% uncertainty interval 1·39–1·59) worldwide in people aged 10–24 years, of which 61% occurred in males. 32·7% of all adolescent deaths were due to transport injuries, unintentional injuries, or interpersonal violence and conflict; 32·1% were due to communicable, nutritional, or maternal causes; 27·0% were due to non-communicable diseases; and 8·2% were due to self-harm. Since 1950, deaths in this age group decreased by 30·0% in females and 15·3% in males, and sex-based differences in mortality rate have widened in most regions of the world. Geographical variation has also increased, particularly in people aged 10–14 years. Since 1980, communicable and maternal causes of death have decreased sharply as a proportion of total deaths in most GBD super-regions, but remain some of the most common causes in sub-Saharan Africa and south Asia, where more than half of all adolescent deaths occur. Annual percentage decrease in all-cause mortality rate since 1990 in adolescents aged 15–19 years was 1·3% in males and 1·6% in females, almost half that of males aged 1–4 years (2·4%), and around a third less than in females aged 1–4 years (2·5%). The proportion of global deaths in people aged 0–24 years that occurred in people aged 10–24 years more than doubled between 1950 and 2019, from 9·5% to 21·6%. Interpretation Variation in adolescent mortality between countries and by sex is widening, driven by poor progress in reducing deaths in males and older adolescents. Improving global adolescent mortality will require action to address the specific vulnerabilities of this age group, which are being overlooked. Furthermore, indirect effects of the COVID-19 pandemic are likely to jeopardise efforts to improve health outcomes including mortality in young people aged 10–24 years. There is an urgent need to respond to the changing global burden of adolescent mortality, address inequities where they occur, and improve the availability and quality of primary mortality data in this age group.

Project description:This study aimed to analyze the relationship between perceived aquatic competence (PAC) and real aquatic competence (RAC) in 6 to 10 year old children in skills identified as relevant for surviving an aquatic accident. The study sample consisted of 105 children (8.2 + 1.3 years old). Two age groups were examined separately [G1, 6 to 7 years (n = 53); G2, 8 to 10 years (n = 52)]. Children's aquatic competence was evaluated twice for skills linked to the risk of drowning: Firstly, using a common swimsuit (simple condition) and secondly wearing a t-shirt (complex condition). The PAC was assessed by questionnaire interview. Pearson correlation coefficients, pairwise, and independent t-test comparisons were performed with a significance level of 5%. Similar levels of PAC were found among both age groups for all measured skills, excepted for breath control during swimming (p < 0.05). However, PAC differs significantly (p < 0.001) from RAC (in simple and complex conditions) only in G1. Correlations between PAC and RAC were modest for all measured skills in both age-groups. Significant differences were found between RAC in simple and complex conditions in both groups (p < 0.01). Age contributes to a higher perceived aquatic competence in skills related to the risk of drowning.

Project description:BackgroundGood hearing is a fundamental skill that allows children to develop properly, both socially and intellectually. In contrast to defects in inner ear function, however, auditory processing disorders (APDs)-which can affect up to 2-3% of school-children-are not easily identified with basic screening programs and must be diagnosed using special tests. Although such psychoacoustic tests are available, the scores achieved depend highly on the social, cultural, and linguistic characteristics of the population, and norms must be established for each population separately. Reference values are still lacking for the Polish population, especially for children in school-age, so that practitioners must interpret test scores themselves, often intuitively or using potentially biased thresholds from other countries.Materials and methodsWe investigated a sample of 94 Polish schoolchildren with normal hearing, divided into four age groups: from 7 years-olds to 10 years-olds. All children had no speech or language development disorder, learning problem, or symptom of APD. Participants were volunteers who had previously taken part in a large screening study. The group consisted of 56 girls (60%) and 38 boys (40%) with an average age of 8.6 years (SD = 1.1). The test battery included the Duration Pattern Test (DPT), Frequency Pattern Test (FPT), Time-Compressed Speech Test (CST), and Dichotic Digit Test (DDT).ResultsThe scores on all tests increased consistently with age. The difference between each age-group for DPT, CST, and left- and right-ear DDT tests was significant (Kruskal-Wallis test, p-values = 0.002, 0.006, 0.005, 0.020, respectively), but the effect of age on the FPT test was not (p-value = 0.143). The analysis showed a clear and significant separation between a merged group of ages 7 and 8 and another of ages 9 and 10. We, therefore, propose, for each test, separate reference values for these two particular age-groups. Using thresholds based on a 10% quantile, we offer the following reference values for ages 7-8 and 9-10 respectively: DPT, 28.5% and 53.8%; FPT, 18.5% and 27.5%; CST, 68.6% and 77.2%; left-ear DDT, 34.3% and 52.5%; right-ear DDT, 56% and 72.5%.ConclusionThe scores on psychoacoustic tests to diagnose APD differ between cultures and linguistic backgrounds. Clinicians should, therefore, use norms that have been designed for the population most similar to their patients. Here, we report the use of a test battery designed for the Polish language that accounts for various aspects of APD when screening school children. Together with a full methodology of those tests, we provide norms that can be used as cut-offs in clinical diagnosis. Practitioners are invited to use them to obtain more accurate, evidence-based decisions.

Project description:BackgroundThe World Health Organization (WHO) released guidelines for physical activity, sedentary behavior, and sleep for children under 5 years of age in 2019. In response to these guidelines, this pilot study aimed to (i) determine the proportion of preschool children (ages 3-4 years) who met the WHO guidelines; (ii) examine the feasibility of the proposed protocol for the SUNRISE study; and (iii) assess the impact of the COVID-19 pandemic on movement behaviors of preschool children in Bangladesh.MethodsTime spent in physical activity, sedentary behavior and sleep were objectively measured using two types of accelerometers (ActiGraph wGT3x-BT and ActivPAL4). Screen time and sleep quality were assessed via parent questionnaire. Fine and gross motor skills were measured using the Ages and Stages Questionnaire (3rd edition). Three executive functions were assessed using the Early Years Toolbox. Focus groups were conducted with parents and childcare staff to determine the feasibility of the protocol. Follow-up data during COVID-19 pandemic was collected from parents over phone.ResultsData from 63 preschool-aged children and their parents was analyzed in this pilot study. Only three children (4.7%) met all components of the WHO guidelines. Separately, children meeting physical activity, sedentary screen time and sleep guidelines were 71.9%, 17.5%, and 59.7% respectively. The proportion of all children who were developmentally on-track for the gross and fine motor skills was 58.7% and 50.8%, respectively. Parents and educators reported that the protocol was feasible except for the activPAL-4 accelerometer. Approximately, 39% of children (14 out of 37) who wore this device developed itchy skin and rashes resulting in the suspension of using this device mid-way through data collection. During COVID-19, there was a significant decrease in children's total physical activity (- 193 min/day), and time spent outside on weekdays (- 75 min/day) and weekend days (- 131 min/day) and a significant increase in sedentary screen time (+85 min/day).ConclusionOnly a low proportion of children met the WHO guidelines. Methods and devices (except ActivPAL4) used in this pilot study proved to be feasible and this has paved the way to conduct the main SUNRISE study in Bangladesh. Future measures should be taken to address the issue of movement behaviors of children during the time of pandemics like COVID-19.

Project description:To examine the differences in hospital emergency psychiatric presentations for self-harm of children and adolescents during the covid-19 lockdown in March and April 2020 compared with the same period in 2019. Retrospective cohort study. We used electronic patient records from 23 hospital emergency departments in ten countries grouped into 14 areas. We examined data on 2073 acute hospital presentations by 1795 unique children and adolescents through age 18. We examined the total number of emergency psychiatric hospital presentations and the proportion of children and adolescents presenting with severe self-harm as our two main outcome measures. In addition, we examined sociodemographic and clinical characteristics and clinical management variables for those presenting with self-harm. To compare the number of hospital presentations between 2020 and 2019 a negative binomial model was used. For other variables, individual participant data (IPD) meta-analyses were carried out. Emergency psychiatric hospital presentations decreased from 1239 in 2019 to 834 in 2020, incident rate ratio 0.67, 95% CI 0.62-0.73; p?<?0.001. The proportion of children and adolescents presenting with self-harm increased from 50% in 2019 to 57% in 2020, odds ratio 1.33, 1.07-1.64; p?=?0.009 but there was no difference in the proportion presenting with severe self-harm. Within the subpopulation presenting with self-harm the proportion of children and adolescents presenting with emotional disorders increased from 58 to 66%, odds ratio 1.58, 1.06-2.36; p?=?0.025. The proportion of children and adolescents admitted to an observation ward also decreased from 13 to 9% in 2020, odds ratio 0.52, 0.28-0.96; p?=?0.036. Service planners should consider that, during a lockdown, there are likely to be fewer emergency psychiatric presentations. Many children and adolescents with psychiatric emergencies might not receive any service. A focus on developing intensive community care services with outreach capabilities should be prioritised.

Project description:To evaluate antibody persistence of Aleph inactivated split influenza vaccine, 3308 healthy Chinese people more than 3 years old were enrolled in a hemagglutination inhibition (HI) assay before vaccination, 641 were screened by HI assay negative, 437 of which received one dose of Aleph inactivated split influenza vaccine and 204 of which received one dose of control vaccine (recombinant hepatitis B). After vaccination, the receivers were collected blood at 1st month, 3rd month, 6th month and 12th month for Aleh influenza vaccine antibody persistence assess. The antibody test were determined by hemagglutination inhibition (HI) assay. There were significant difference in antibody geometric mean titer between experimental group and control at 1st month and 3rd month after vaccination. Influenza antibody could persist at least up to 3rd month. Because of the local spring influenza epidemic, we could not analyze the results of 6th and 12th month. Aleph influenza vaccines showed good immune persistence in healthy volunteers at least in the 3 months after vaccination. Influenza viruses are important human respiratory pathogens. Immunization is widely acknowledged to currently be the most effective method of minimizing the impact of pandemic influenza. Through we have checked many references about Influenza vaccine, the duration of protective antibody for influenza vaccines are still not available. Based on this situation and our previous work, (11) Influenza vaccine antibody duration analyze are necessary. This manuscript presents data on the persistence of Hemagglutination Inhibition (HI) immune response against the A/California/7/2009(H1N1), A/Peth/16/2009(H3N2) strain and B/Brisbane/60/2008. 641 were screened from 3302 volunteers by HI test of influenza A and confirmed enrollment based on the antibodies titer less than 1:10. After administered with one dose of Aleph influenza vaccine, blood samples were collected. 437 subjects (3-10 y: 131; 11-17 y: 110; 18-54 y: 69; ? 55 y: 127) were vaccinated influenza vaccine as test group. 204 subjects (3-10 y: 70; 11-17 y: 47; 18-54 y: 28; ? 55 y: 59) were vaccinated recombinant hepatitis B vaccine as control group. Immunogenicity end points were based on the European licensure criteria for pandemic influenza vaccines. The persistence of HI immune response against the vaccine strain was assessed through GMT. The immunogenicity of the Aleph influenza vaccine induced all reached the standards at 1st month and GMTs peak could persist at least up to 3rd month. (This study has been registered at clinicaltrials.gov under registration no. NCT01758185.). Because of the local spring influenza epidemic we could not analyze the results of 6th and 12th month. Aleph influenza vaccines showed good immune persistence in healthy volunteers at least in the 3 months after vaccination.

Project description:Quality of language comprehension determines performance in all kinds of activities including academics. Processing of words initially develops as auditory, and gradually extends to visual as children learn to read. School failure is highly related to listening and reading comprehension problems. In this study we analyzed sex-differences in comprehension of texts in Spanish (standardized reading test PROLEC-R) in three modalities (visual, auditory, and both simultaneously: dual-modality) presented to 12-14-years old students, native in Spanish. We controlled relevant cognitive variables such as attention (d2), phonological and semantic fluency (FAS) and speed of processing (WISC subtest Coding). Girls' comprehension was similar in the three modalities of presentation, however boys were importantly benefited by dual-modality as compared to boys exposed only to visual or auditory text presentation. With respect to the relation of text comprehension and school performance, students with low grades in Spanish showed low auditory comprehension. Interestingly, visual and dual modalities preserved comprehension levels in these low skilled students. Our results suggest that the use of visual-text support during auditory language presentation could be beneficial for low school performance students, especially boys, and encourage future research to evaluate the implementation in classes of the rapidly developing technology of simultaneous speech transcription, that could be, in addition, beneficial to non-native students, especially those recently incorporated into school or newly arrived in a country from abroad.
