Assessing the social validity of telehealth-based applied behavior analysis services for autism spectrum disorder

During the COVID-19 pandemic, applied behavior analysis services for many autistic individuals were transitioned to telehealth. The current study assessed caregiver-reported quality of life (QoL) and social validity for families of autistic children receiving only telehealth services (n = 96) or a combination of telehealth and in-person services (n = 173). Barriers to the telehealth experience were analyzed via an ANOVA, and the impact of funding source was analyzed using an independent samples t-test. Caregivers reported benefit across QoL and social validity items, with scores ranging from 3.31 to 4.44 (1 = least benefit, 5 = most benefit). While many caregivers reported no barriers regarding technology (44.61%), childcare (69.52%), and employment (64.68%), the presence of those barriers significantly impacted QoL and social validity scores. Funding source was not found to have a significant impact. Overall, caregivers found value in their child's telehealth services. Clinicians have an obligation to mitigate barriers to ensure the success of the intervention. © 2023 John Wiley & Sons Ltd.

Evaluation of Cycle Threshold Values in Patients with Symptomatic COVID-19 Infection

Background. One of the tests used to identify COVID-19 infections is the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reverse transcriptase quantitative polymerase chain reaction (RT-qPCR) test. There is a measure known as the cycle threshold (Ct) value, which provides an indirect measure of viral load. It has been proposed that the Ct value could help with clinical decisions regarding duration of isolation. We hypothesize that Ct values will correlate with symptom duration in a population of veterans with COVID-19 infection. Methods. We reviewed the records of patients presenting to the emergency department (ED) or admitted to Audie L. Murphy VA Medical Center in San Antonio, Texas with positive SARS-CoV-2 PCR tests. We looked at patients who received multiple SARS-CoV-2 RT-qPCR tests. We compared date of onset of symptoms and cycle threshold values from their initial test to another test ordered after 7, 10, and 20 days from symptom onset. We recorded the Ct value for the N2 and E genes. Patients were classified into mild, severe and critical based on Center for Disease Control and Prevention (CDC) criteria. A Ct value of >30 as threshold for transmissible disease was used based on previously published studies. Results. We identified 49 patients with more than two SARS-CoV-2 RT-qPCR tests. Patients with mild disease with tests less than or equal to ten days from symptom onset (n=10) had a mean Ct value 23.2 (±5.6) and 26.0 (±5.8) for the E and N2 genes. Patients with mild disease with tests greater than ten days from symptom onset (n=4) had mean Ct values of 26.0 (±6.5) and 27.8 (±6.8). When we stratified the patient population by disease severity, patients with severe and critical disease with tests less than ten days from symptom onset (n=24) had mean Ct values of 20.1 (±7.3) and 23.4 (±7.5). Patients with severe and critical disease greater than twenty days (n=6) had Ct values of 29.0 (±5.1) and 31.1 (±5.4). Conclusion. We found that Ct values increased with longer symptom duration. We currently use the CDC criteria to discontinue isolation at ten days for mild disease and twenty days for severe and critical disease. The findings of this study suggest that our current practice for duration of isolation correlates with increasing Ct values near or above the threshold for transmissible disease.

Impaired coronary flow reserve in athletes with long-term cardiovascular symptoms after COVID-19

Introduction: Cardiovascular symptoms post-acute sequelae of SARS-CoV-2 infection (CV-PASC) have been increasingly recognized, but the underlying pathobiology is unclear. Endothelial and cardiac pericyte ACE2 receptors are important targets of SARS-CoV-2, resulting in virally-induced endothelial activation, which may adversely affect the coronary microvasculature and impair myocardial performance. We hypothesized that athletes with CV-PASC have microvascular and subclinical myocardial dysfunction. Methods: We compared 15 athletes with CV-PASC with 7 control athletes without prior COVID-19 using regadenoson stress cardiac magnetic resonance (CMR). All athletes participated in >6 hours of endurance activities per week. We analyzed CMR volumes, function, global circumferential strain (GCS), late gadolinium enhancement (LGE), and coronary flow reserve (CFR) by coronary sinus method. Values presented as median [IQR]. Results: CMR in CV-PASC athletes occurred 102 [66,123] days post-SARS-CoV-2 infection. There were no differences in chamber volumes, function, or LGE between groups. One CV-PASC athlete had acute myocarditis (7%). CVPASC athletes had decreased CFR compared with control athletes (Figure 1). Multiple CV-PASC participants had CFR below the 95% CI of the controls and reported normal values from the literature (2.9 and 2.5, respectively). GCS was worse in CV-PASC athletes at the base (-23.7% [-21.6,-26.4] vs -31.1% [-27.3,-33.0], p=0.01), mid-LV (-21.5% [-18.5,-22.8] vs -28.5 [-25.4,-29.9], p=0.008), and apex (-27.1% [-24.1,-29.9] vs -30.6% [-27.8,-38], p=0.07), though the apex did not reach statistical significance. Conclusions: This pilot case-control study found CV-PASC athletes had reduced CFR and associated subclinical myocardial dysfunction as assessed by GCS compared to control athletes. These findings suggest coronary microvascular dysfunction related to endothelial injury may mediate CV-PASC symptoms.

Are Rurality, Area Deprivation, Access to Outside Space, and Green Space Associated with Mental Health during the COVID-19 Pandemic? A Cross Sectional Study (CHARIS-E)

The study investigated if rurality, area deprivation, access to outside space (Study 1), and frequency of visiting and duration in green space (Study 2) are associated with mental health during the COVID-19 pandemic and examined if individual demographics (age, gender, COVID-19 shielding status) and illness beliefs have a direct association with mental health during the COVID-19 pandemic. A serial, weekly, nationally representative, cross-sectional, observational study of randomly selected adults was conducted in Scotland during June and July 2020. If available, validated instruments were used to measure psychological distress, individual demographics, illness beliefs, and the following characteristics: Rurality, area deprivation, access to residential outside space, frequency of visiting, and duration in green space. Simple linear regressions followed by examination of moderation effect were conducted. There were 2969 participants in Study 1, of which 1765 (59.6%) were female, 349 (11.9%) were in the shielding category, and the median age was 54 years. There were 502 participants in Study 2, of which 295 (58.60%) were female, 58 (11.6%) were in shielding category, and the median age was 53 years. Direct effects showed that psychological distress was worse if participants reported the following: Urban, in a deprived area, no access to or sharing residential outside space, fewer visits to green space (environment), younger, female, in the shielding category (demographics), worse illness (COVID-19) representations, and greater threat perception (illness beliefs). Moderation analyses showed that environmental factors amplified the direct effects of the individual factors on psychological distress. This study offers pointers for public health and for environmental planning, design, and management, including housing design and public open space provision and regulation.
