ABSTRACT
Introduction: Anterior nasal sampling (AN) might be more convenient for patients than NP sampling to diagnose coronavirus disease. This study investigated the feasibility of rapid antigen tests for AN sampling, and the factors affecting the test accuracy. Methods: This single-center prospective study evaluated one qualitative (ESP) and two quantitative (LUMI and LUMI-P) rapid antigen tests using AN and NP swabs. Symptomatic patients aged 20 years or older, who were considered eligible for reverse-transcription quantitative polymerase chain reaction using NP samples within 9 days of onset were recruited. Sensitivity, specificity, and positive and negative concordance rates between AN and NP samples were assessed for the rapid antigen tests. We investigated the characteristics that affected the concordance between AN and NP sampling results. Results: A total of 128 cases were recruited, including 28 positive samples and 96 negative samples. The sensitivity and specificity of AN samples using ESP were 0.81 and 1.00, while those of NP samples were 0.94 and 1.00. The sensitivity of AN and NP samples was 0.91 and 0.97, respectively, and specificity was 1.00, for both LUMI and LUMI-P. The positive concordance rates of AN to NP sampling were 0.87, 0.94, and 0.85 for ESP, LUMI, and LUMI-P, respectively. No factor had a significant effect on the concordance between the sampling methods. Conclusions: ESP, LUMI, and LUMI-P showed practical diagnostic accuracy for AN sampling compared to NP sampling. There was no significant factor affecting the concordance between AN and NP sampling for these rapid antigen tests. © 2022 Japanese Society of Chemotherapy and The Japanese Association for Infectious Diseases
ABSTRACT
Background: There is growing interest in parent-delivered interventions (PDI) for children with autism. Treatment fidelity has been associated with child outcomes in PDI but little is known about what impacts fidelity. One factor not previously examined is parents' resolution to the autism diagnosis which involves adjusting expectations about the child and sensitively responding to their cues, strengths and needs. Relatively little is known about resolution in the context of autism but there is evidence of an association between resolution and parent wellbeing. Method: The study adopted a mixed methods approach to examine whether there is an association between PDI fidelity and parent resolution to diagnosis, and whether resolution is associated with parent wellbeing. Parents of 31 preschool children diagnosed with autism who attended up to 12 Parent-delivered Early Start Denver Model (P-ESDM) coaching sessions participated in the study. A thematic analysis of parent interviews was also undertaken to identify themes raised by resolved and unresolved parents in interviews. Results: There was no difference in overall mean fidelity scores between resolved and unresolved parents. Those classified as resolved had lower depression scores and parenting stress scores than parents classified as unresolved. The qualitative analysis revealed that parents' perceptions of their child's progress and their hopes for the future appeared to distinguish resolved and unresolved parents. Conclusions: Findings suggest that parent wellbeing and child progress may predict resolution which was not related to parent treatment fidelity in this study. Parent wellbeing and resolution status should be assessed at entry to PDI.
