Exploring the Perspectives of Parents of Individuals with Autism from Low-Resourced Communities to Inform Family Navigator Programs.

Family navigator programs (i.e., programs to train family navigators) are becoming increasingly common among families of children with autism. Family navigators (i.e., individuals who help families access evaluations and/or services) may be parents of children with autism themselves or health professionals. Extant research has shown that family navigators can help families receive timely diagnostic evaluations and initial services. Yet, the development of family navigator programs is unclear; by exploring the input of families of children with autism, such programs can be responsive to family needs. In this study, we extend the extent literature by exploring the lived experiences of 12 parents of autistic children from low-resourced communities to inform the development of a family navigator program. Findings demonstrated that navigator programs need to prepare navigators to address barriers such as limited knowledge and difficulty accepting an autism diagnosis. Navigator programs should teach navigators to use strategies with families including educating families about services and connecting families with peer support. Program content should reflect direct services, government services, and advocacy strategies. Notably, for true improvements to service access for all autistic children, systemic changes are also needed in the service delivery systems. Implications are discussed.

Examining the associations among knowledge, empowerment, and advocacy among parents of transition-aged youth with autism.

LAY ABSTRACT: Parents of individuals with autism face many challenges in finding appropriate services and support for their children, and they also play an important role in advocating for their children's rights and needs. Despite the increasing availability of advocacy programs, it is still uncertain how to best encourage parents to advocate for their children. This study explored the connection between parents' knowledge and sense of empowerment, and how these factors relate to three types of advocacy activities (i.e. individual, peer, and systemic). The findings reveal that feeling empowered has a greater impact on advocacy than simply having knowledge. In addition, the study found that individual advocacy correlates to more peer advocacy, which also correlates to more systemic advocacy. These results can help researchers and professionals to better develop programs to increase parent advocacy and, in turn, help improve the lives of individuals with autism.

Importance of parental involvement in paediatric palliative care in Hong Kong: qualitative case study.

OBJECTIVE: To compare and contrast the perceived care needs of children with life-limiting conditions (CLLC) from the perspectives of the children, parents and healthcare providers. DESIGN: A qualitative case study method using semistructured interviews was employed with a within-case and across-case analysis. Themes and subthemes emerging from the cases were compared and contrasted in the across-case analysis to explore the similarities and variations in participant perceptions. SETTING/PARTICIPANTS: The setting was the paediatric departments of five regional hospitals in Hong Kong. Twenty-five sets of informants (CLLC-parent-healthcare provider) were recruited, with 65 individual interviews conducted. RESULTS: A total of 3784 units of analysis were identified, resulting in three themes with subthemes. 'Living with the disease' (55.8%) occupied the largest proportion, followed by 'information and understanding about the disease' (27.4%), and 'care support and palliative care' (16.8%). Healthcare provider support mainly focused on physical concerns. Family and social support were present, but carer stress created tension between couples. Doctors were the primary source of medical information, but the parents had to seek further information via the internet and support from patient groups. There was a perceived need for better coordination and collaboration of care. The palliative care approach coordinated by nurses was seen as helpful in addressing the care needs of the CLLC. CONCLUSIONS: This original study identified the importance of palliative care with active engagement of parents which can address the service gap for CLLC.

Clinical, neuroimaging, and behavioural risk factors for neurocognitive impairment in Chinese patients with haemophilia: A multicentre study.

BACKGROUND: Few studies have evaluated the impact of subclinical microstructural changes and psychosocial factors on cognitive function in patients with haemophilia. OBJECTIVES: To determine the prevalence and characteristics of cognitive impairment in patients with haemophilia, and identify associated risk factors. METHODS: We recruited haemophilia A or B patients who were aged ≥10 years old from three public hospitals in Hong Kong. A neurocognitive battery was administered to evaluate their attention, memory, processing speed and cognitive flexibility performances. They also underwent magnetic resonance imaging to identify cerebral microbleeds. Validated self-reported questionnaires were administered to assess their mental health status and adherence to prophylactic treatment. General linear modelling was used to investigate the association of neurocognitive outcomes with risks factors, adjusting for age and education attainment. RESULTS: Forty-two patients were recruited (median age 32.0 years; 78.6% haemophilia A; 80.9% moderate-to-severe disease). Six patients (14.3%) had developed cerebral microbleeds. A subgroup of patients demonstrated impairments in cognitive flexibility (30.9%) and motor processing speed (26.2%). Hemarthrosis in the previous year was associated with worse attention (Estimate = 7.62, 95% CI: 1.92-15.33; p = .049) and cognitive flexibility (Estimate = 8.64, 95% CI: 2.52-13.29; p = .043). Depressive (Estimate = 0.22, 95% CI: 0.10-0.55; p = .023) and anxiety (Estimate = 0.26, 95% CI: 0.19-0.41; p = .0069) symptoms were associated with inattentiveness. Among patients receiving prophylactic treatment (71.4%), medication adherence was positively correlated with cognitive flexibility (p = .037). CONCLUSION: A substantial proportion of patients with haemophilia demonstrated cognitive impairment, particularly higher-order thinking skills. Screening for cognitive deficits should be incorporated into routine care. Future studies should evaluate the association of neurocognitive outcomes with occupational/vocational outcomes.

A Tale of Two Adaptations of a Special Education Advocacy Program.

Special education advocacy programs support families to secure services for their children with intellectual and developmental disabilities. Although research demonstrates the efficacy of one such program (the Volunteer Advocacy Project), its effectiveness when replicated by others is unknown. Replication research is critical to ensure that programs can remain effective. The purpose of this study was to explore the adaptation process for two agencies that replicated an advocacy program. Quantitative and qualitative data were collected to examine feasibility, acceptability, and effectiveness. Although it took resources to replicate the advocacy program, agencies reported ongoing implementation would be easier once adaptations were completed. The adapted programs were effective in increasing participants' knowledge, empowerment, advocacy, and insiderness. Implications for research and practice are discussed.

Parental Perceptions of Service Access for Transition-Aged Youth With Autism During COVID-19.

Services are critical for youth with autism spectrum disorder (ASD), especially during the transition to adulthood. Under the best of circumstances, though, it can be difficult to access needed adult services. With COVID-19, services were more difficult to obtain and retain. In this study, we explored parent perceptions of accessing new services and maintaining current services during the first year of the COVID-19 pandemic. Structured interviews were conducted with 65 parents of transition-aged youth (aged 16-26) with ASD living in three states (IL, TN, and WI) in the United States. None of the participants reported receiving new services during the pandemic, and many struggled to access services via online applications. In addition, participants reported that service suspensions and changes in modality (e.g., from in-person to telehealth) were spearheaded by professionals and not families. Participants, especially those in TN, were more likely to pay out-of-pocket for services during the COVID-19 pandemic to compensate for service disruptions. Implications for research and practice are discussed.

Outcome prediction of chronic myeloid leukemia (CML) in children.

We evaluated the feasibility of existing risk assessment tools for chronic myeloid leukemia (CML) in children. Fifty-five patients with newly diagnosed CML between 1996 and 2019 were included. Forty-nine patients presented in chronic phase, thirty-six of whom were treated with upfront tyrosine kinase inhibitor (CP-TKI group); one presented in accelerated phase and four in blastic phase. Treatment, survival, responses, and tolerance were evaluated. All patients in the CP-TKI group received imatinib as their first TKI treatment. The 10-year overall survival (OS), progression-free survival (PFS), and event-free survival (EFS) of TKI-treated group was 97%, 91.4%, and 72.3%, respectively. At 60 months, the rates of major molecular response were 81.2% and deep molecular response was 67.5%. The EUTOS long-term survival (ELTS) risk grouping did not predict OS, PFS, or EFS. The IMAFAIL risk groups were correlated with the risk of imatinib failure. Further studies are required to modify the existing risk assessment tools for children.

The Efficacy and Impact of a Special Education Legislative Advocacy Program Among Parents of Children with Disabilities.

With the looming reauthorization of the Individuals with Disabilities Education Act (IDEA), it is important for parent input to inform legislative changes. Unfortunately, parent input has been limited in past IDEA reauthorizations. Thus, it is critical to develop and test interventions to improve parent legislative advocacy. With 37 parents of children with disabilities, we conducted a randomized controlled trial to determine the efficacy and impact of an advocacy program. Results indicate significant increases in special education knowledge and special education legislative advocacy activities for the intervention (versus waitlist-control) group. However, there were no significant changes in civic engagement. Implications for research and practice are discussed.

The role of parental advocacy in addressing service disparities for transition-aged youth on the autism spectrum.

LAY ABSTRACT: It can be difficult for youth on the autism spectrum to get the services they need after they leave high school. Because of this, many studies have examined the different factors that are related to service access. These studies have shown that youth on the autism spectrum who belong to an underrepresented racial or ethnic group or whose families have lower incomes are less likely to receive the services that they need. However, it is difficult or impossible to change things like race/ethnicity or family income. It is important to also identify factors that might improve service access that we can change. One potential factor that fits into this category is parental advocacy activities. Using data collected from 185 parents of youth on the autism spectrum, we found that more parental advocacy activities were related to youth receiving more services, even after accounting for variables related to the functioning of the youth (e.g. whether they have an intellectual disability, their autism symptom severity) and demographic information about the family (e.g. state in which they live, parental race/ethnicity, and family income). Our findings suggest that building parental advocacy skills may be one important way to increase the number of services that youth on the autism spectrum receive as they transition to adulthood.

Hepatitis B Virus Seropositivity Is a Poor Prognostic Factor of Pediatric Hepatocellular Carcinoma: a Population-Based Study in Hong Kong and Singapore.

BACKGROUND: Hepatocellular carcinoma (HCC) is a rare hepatic malignancy in children. Hepatitis B virus (HBV) infection is a key predisposing factor in endemic regions but its impact on outcome has not been studied. We aim to evaluate the prognostic implication of HBV seropositivity and role of cancer surveillance in children with HCC from East Asian populations with national HBV vaccination. METHODS: Review of population-based databases for patients (< 18 years old) diagnosed with HCC from 1993 to 2017 in two Southeast Asian regions with universal HBV vaccination (instituted since 1988 and 1987 in Hong Kong and Singapore, respectively). RESULTS: Thirty-nine patients were identified (Hong Kong, 28; Singapore, 11). Thirty were male; median age at diagnosis was 10.8 years (range, 0.98-16.6). Abdominal pain was the commonest presentation while five patients were diagnosed through surveillance for underlying condition. Alpha-fetoprotein was raised in 36 patients (mean, 500,598 ng/ml). Nineteen had bilobar involvement, among the patients in whom pretreatment extent of disease (PRETEXT) staging could retrospectively be assigned, 3 had stage I, 13 had stage II, 4 had stage III, and 11 had stage IV disease. Seventeen had distant metastasis. HBsAg was positive in 19 of 38 patients. Two patients had fibrolamellar HCC. Upfront management involved tumor resection in 16 (liver transplantation, 2), systemic chemotherapy in 21, interventional procedures in 6 [transarterial chemoembolization (TACE), 5, radiofrequency ablation (RFA), 1], and radiotherapy in 4 (selective internal radiation, 3, external beam radiation, 1). Five-year event-free survival (EFS) and overall survival (OS) were 15.4 ± 6.0 and 26.1 ± 7.2%, respectively. Patient's HBsAg positivity, metastatic disease and inability to undergo definitive resection represent poor prognostic factors in univariate and multivariable analyses. Patients diagnosed by surveillance had significantly better outcome. CONCLUSION: Pediatric HCC has poor outcome. HBV status remains relevant in the era of universal HBV vaccination. HBV carrier has inferior outcome and use of surveillance may mitigate disease course.

Massively parallel variant characterization identifies NUDT15 alleles associated with thiopurine toxicity.

As a prototype of genomics-guided precision medicine, individualized thiopurine dosing based on pharmacogenetics is a highly effective way to mitigate hematopoietic toxicity of this class of drugs. Recently, NUDT15 deficiency was identified as a genetic cause of thiopurine toxicity, and NUDT15-informed preemptive dose reduction was quickly adopted in clinical settings. To exhaustively identify pharmacogenetic variants in this gene, we developed massively parallel NUDT15 function assays to determine the variants' effect on protein abundance and thiopurine cytotoxicity. Of the 3,097 possible missense variants, we characterized the abundance of 2,922 variants and found 54 hotspot residues at which variants resulted in complete loss of protein stability. Analyzing 2,935 variants in the thiopurine cytotoxicity-based assay, we identified 17 additional residues where variants altered NUDT15 activity without affecting protein stability. We identified structural elements key to NUDT15 stability and/or catalytical activity with single amino acid resolution. Functional effects for NUDT15 variants accurately predicted toxicity risk alleles in patients treated with thiopurines with far superior sensitivity and specificity compared to bioinformatic prediction algorithms. In conclusion, our massively parallel variant function assays identified 1,152 deleterious NUDT15 variants, providing a comprehensive reference of variant function and vastly improving the ability to implement pharmacogenetics-guided thiopurine treatment individualization.

Burkitt Lymphoma Presenting as Acute Pancreatitis: Report of 3 Cases and Review of the Literature.

Acute pancreatitis is a rare presentation in Burkitt lymphoma (BL) and may lead to delayed medical or unnecessary surgical treatment. Three cases of BL presenting as acute pancreatitis in the authors' institutions were described. Similar cases reported in the medical literature were collected and described along with the authors' cases. There were 12 cases described in the medical literature and hence a total of 15 cases of BL presenting as acute pancreatitis. Fourteen cases were the first diagnosis, and the other presented at lymphoma relapse. Twelve cases occurred in children under 15 years. Twelve patients had extrapancreatic disease. Three children were treated with surgery before diagnosis. Two patients died. Six of the remaining had adequate follow-up and were surviving in remission 8 months to 16 years after diagnosis. Lymphoma should be included in the differential diagnosis of acute pancreatitis in children. Acute pancreatitis in combination with malignant infiltration on imaging is highly suggestive of BL, especially in the jaundiced child.

Measuring Oral Mucositis of Pediatric Patients with Cancer: A Psychometric Evaluation of Chinese Version of the Oral Mucositis Daily Questionnaire.

OBJECTIVE: Oral mucositis is a frequent clinical condition that has been shown to affect pediatric cancer patients. Oral Mucositis Daily Questionnaire (OMDQ) is one of the few available patient-reported outcome measures to assess the extent and impact of oral mucositis. The objectives of the study were to translate the Mouth and Throat Soreness-Related Questions of the OMDQ into Chinese (OMDQ MTS-Ch) for children and adolescents aged 6-18 years receiving chemotherapy and to evaluate its psychometric properties. METHODS: This was part of a multicenter, prospective cohort study involving two phases. Phase I involved forward-backward translation to fit the cognitive and linguistic age level of the children and adolescents, followed by face and content validation, together with pretesting. In Phase II, which evaluated the internal consistency, test-retest reliability, and discriminant validity, a total of 140 patients completed the OMDQ MTS-Ch for 14 days. RESULTS: The OMDQ MTS-Ch had satisfactory face and content validities. The Cronbach's alpha coefficient of the OMDQ MTS-Ch was 0.984. All of the corrected item-total correlations were higher than 0.90. The test-retest intraclass correlation coefficient between consecutive days for the OMDQ MTS-Ch items ranged from 0.576 to 0.983; the only value that was not over 0.70 was that for the paired study days 7 and 8 for the item of talking. The mean area-under-the-curve OMDQ MTS-Ch item scores were significantly different among patients with different degrees of mucositis severity (P < 0.001), supporting the discriminant validity. CONCLUSIONS: It has been shown that the OMDQ MTS-Ch has a good level of reliability and discriminant validity and can be completed by children aged ≥6 years and adolescents on a daily basis to measure mucositis and its related functional limitations.

Acute Leukemia in Down Syndrome Children in Hong Kong: Retrospective Review.

BACKGROUND: Children with Down syndrome (DS) are at higher risk of developing acute leukemia. Treatment continues to evolve as we accumulate better understanding of the distinctive clinical and biological features of acute leukemia in DS patients. PROCEDURE: A retrospective review of the clinical features, treatment outcomes, and survival of DS children with acute leukemia in Hong Kong from 1993 to 2013 was conducted. Patients were identified from the registry of the Hong Kong Pediatric Hematology and Oncology study group. RESULTS: This cohort included a total of 29 patients with DS. Ten were diagnosed with acute lymphoblastic leukemia and 19 had acute myeloid leukemia (AML). The mean follow-up duration was 8.3 years (range, 0.6 mo to 18.1 y). The 5-year overall survival and event-free survival for DS-acute lymphoblastic leukemia and DS-AML were 65.6%, 54.9%, 89.5%, and 89.5%, respectively. CONCLUSIONS: The clinical characteristics and treatment outcomes of DS patients with acute leukemia in Hong Kong were comparable with results from other international study groups. Patients with DS-AML had a better prognosis.

Central nervous system tumors in chinese children under the age of 3: a population study.

The management of central nervous system tumors in children below the age of 3 years represents a special challenge to pediatric oncologists with distinctive epidemiology, treatment considerations, and prognosis. Population-based epidemiological data on this particular patient group is lacking in Chinese. We reviewed the population-based pediatric tumor registry in Hong Kong between 1999 and 2011. Eighty-one children with primary central nervous system tumors from 0 to 3 years of age were identified (annual incidence: 4.16 cases per 100,000). Forty-one (50.6%) were male and the mean duration of follow-up was 94 months (±8.1). Primary tumors were infratentorial in 43 (53.1%). The tumor types in decreasing frequency were astrocytoma (n=17), medulloblastoma (n=16), ependymoma (n=13), choroid plexus tumor (n=7), primitive neuroectodermal tumor (n=7), atypical teratoid rhabdoid tumor (n=6), germ cell tumor (GCT, n=5), craniopharyngioma (n=4), and ganglioglioma (n=3). Three patients presented antenatally. Treatment included surgery in 82.7%, chemotherapy in 50.6%, and radiotherapy in 25.9%. There were 29 deaths (35.8%) and 19 relapses (23.5%) during the review period with the 1-year overall survival (OS), 5-year OS, 1-year event-free survival (EFS), and 5-year EFS being 79.4% (±4.6), 63.5% (±5.9), 68.9% (±5.3), and 52.5% (±5.9), respectively. Significantly better OS and EFS were observed in patients who received gross total resection, but those with high-grade tumors, antenatal diagnosis, or atypical teratoid rhabdoid tumor/primitive neuroectodermal tumor had worse outcome. Survival did not differ with age. Comparison with statistics from other studies revealed higher rates of embryonal tumor, GCT, and craniopharyngioma in Hong Kong Chinese. Disease outcome appeared to be better in our cohort comparing to previous reports probably due to the higher proportion of GCT locally.

A 20-year prospective study of Wilms tumor and other kidney tumors: a report from Hong Kong pediatric hematology and oncology study group.

BACKGROUND: Renal tumors are one of the most common tumors in children. We aim at evaluating the characteristics and the outcome of Wilms tumor and other malignant kidney tumors in Hong Kong. PROCEDURE: Between January 1990 to December 2010, 68 patients under the age of 18 with malignant renal tumors were diagnosed and received treatment in Hong Kong. Clinical records were updated regularly. Prognostic factors and survival rate were evaluated. RESULTS: Fifty-four patients were diagnosed with Wilms tumor. The annual incidence was estimated to be 2.29 per million. The mean age was 38 months. Median follow-up was 9.2 years. The event-free survival and overall survival rate at 10 years were 85.2% and 92.6%, respectively. A pair of siblings with familial extrarenal Wilms tumor was included. Pulmonary metastasis did exhibit a significant difference in survival rate. Eight cases of clear cell sarcoma of the kidneys were reported and the survival rate was 100%. CONCLUSIONS: The clinical characteristics and outcome of the patients diagnosed Wilms tumor were comparable with other developed countries. Relatively high proportion and excellent outcome were found in clear cell sarcoma of the kidneys.

Timing of adjuvant radiotherapy and treatment outcome in childhood ependymoma.

BACKGROUND: Several trials incorporating adjuvant focal RT for treatment of young children with ependymoma have demonstrated improved survival with acceptable adverse effects. The optimal timing of RT administration is, however, unknown. PROCEDURE: A retrospective review of territory-wide database was performed to identify pediatric patients with ependymoma diagnosed between 1995 and 2011. OS and EFS were compared between patients receiving upfront RT (<150 days of diagnosis), delayed RT (≥150 days of diagnosis), or no RT. RESULTS: Thirty-one patients with intracranial ependymoma were identified. Median age was 3.5 years and 14 (45%) were male. Primary tumor was supratentorial in 10 (32%) and infratentorial in 21 (68%). All patients underwent initial surgery, with gross-total resection (GTR) in 27 (87%). Twelve (39%) received upfront RT, 10 (32%) had delayed RT and 9 (29%) had no RT. During the study period, there were 11 relapses (35%) and 10 deaths (32%). Five-year OS was 69.9% and 5yr-EFS was 49.3%. In univariate analysis, GTR led to improved OS (P < 0.001) and EFS (P = 0.004); superior OS and EFS was observed in patients who received RT when compared with those without (P = 0.018 and 0.011, respectively). Upfront RT also resulted in better OS and EFS than delayed RT (P = 0.049 and 0.014, respectively). No significant effect on survival was observed with age, sex, tumor location, RT dosage, and protocol used. In multivariate analysis, GTR significantly improved OS (P = 0.002) and EFS (P = 0.004). CONCLUSIONS: Our results support the early initiation of adjuvant RT in the multi-modal management of pediatric ependymomas.

Minimal residual disease-based risk stratification in Chinese childhood acute lymphoblastic leukemia by flow cytometry and plasma DNA quantitative polymerase chain reaction.

Minimal residual disease, or MRD, is an important prognostic indicator in childhood acute lymphoblastic leukemia. In ALL-IC-BFM 2002 study, we employed a standardized method of flow cytometry MRD monitoring for multiple centers internationally using uniformed gating, and determined the relevant MRD-based risk stratification strategies in our local patient cohort. We also evaluated a novel method of PCR MRD quantitation using peripheral blood plasma. For the bone marrow flow MRD study, patients could be stratified into 3 risk groups according to MRD level using a single time-point at day-15 (Model I) (I-A: <0.1%, I-B: 0.1-10%, I-C: >10%), or using two time-points at day-15 and day-33 (Model II) (II-A: day-15<10% and day-33<0.01%, II-B: day-15 ≥ 10% or day-33 ≥ 0.01% but not both, II-C: day-15 ≥ 10% and day-33 ≥ 0.01%), which showed significantly superior prediction of relapse (p = .00047 and <0.0001 respectively). Importantly, patients with good outcome (frequency: 56.0%, event-free survival: 90.1%) could be more accurately predicted by Model II. In peripheral blood plasma PCR MRD investigation, patients with day-15-MRD ≥ 10(-4) were at a significantly higher risk of relapse (p = 0.0117). By multivariate analysis, MRD results from both methods could independently predict patients' prognosis, with 20-35-fold increase in risk of relapse for flow MRD I-C and II-C respectively, and 5.8-fold for patients having plasma MRD of ≥ 10(-4). We confirmed that MRD detection by flow cytometry is useful for prognostic evaluation in our Chinese cohort of childhood ALL after treatment. Moreover, peripheral blood plasma DNA MRD can be an alternative where bone marrow specimen is unavailable and as a less invasive method, which allows close monitoring.
