A text messaging intervention and quality of life in adolescents with solid organ transplants.

BACKGROUND: Facilitating communication between adolescents and HCP outside of appointments may enhance patient experience and outcomes. The purpose of this study was to determine whether SMS enhances the healthcare experience, QoL, and medication adherence in adolescent SOT patients. METHODS: This was a prospective observational study of an SMS platform (WelTel Inc) for SOT patients aged 12-19 years. QoL was assessed before and after using the PedsQL™ Transplant Module. Medication adherence was assessed with the frequency of therapeutic tacrolimus levels and variation based on control chart analysis. Patient experience and engagement was evaluated with surveys, response rate to messages, and number of clinical conversations (>2 messages). RESULTS: Twenty-three patients were included (median age 15.7 years (IQR 13.6-17.1)). Median intervention duration was 13.5 months (range 4.0-16.7 months). There was a 68% response rate (742/1095) with 375 clinical conversations. The majority of patients reported the intervention provided a positive outlook on their health (17/23), was useful (18/23), and improved their connection to HCPs (17/23). Following the intervention, there was no significant difference in the median scaled QoL scores (pre-intervention: 81 (IQR 76.5-93.3), post-intervention: 78 (IQR 76-93); p = .37), mean percentage of therapeutic tacrolimus levels (pre-intervention: 52 ± 25%, post-intervention: 65 ± 17%; p = .07), or variation on control chart analysis of tacrolimus levels. CONCLUSIONS: The WelTel messaging platform provided supplemental clinical care for a group of adolescent SOT patients that enhanced their healthcare experience. Patient QoL and adherence were unchanged following the intervention and remained at a high level.

Physical Activity in Paediatric Long QT Syndrome Patients.

Background: Physical activity (PA) is important for cardiovascular health as well as social and emotional well-being of children. Patients with long QT syndrome (LQTS) often face PA restrictions and are often prescribed beta-blockers for disease management. The aim of this study was to determine if PA levels were lower in patients with LQTS compared with healthy controls. Methods: Participants with LQTS from an inherited arrhythmia clinic completed the Physical Activity Questionnaire for Children and Adolescents (PAQ-C/A) and an exercise stress test. PAQ score (a general measure of PA for youth, unitless) and endurance time were compared with healthy controls. Results: Twenty-three patients with LQTS completed the PAQ and had an exercise stress test within a year of having completed the PAQ. No difference was observed in PAQ scores between LQTS and control groups (LQTS: 2.3 ± 0.15 vs controls: 2.3 ± 0.18; P = 0.78). There was no effect of age on PA in patients with LQTS (P > 0.05), whereas PA significantly decreased in controls with age (eg, 11-12 vs 17-20 years: 3.2 ± 0.07 vs 1.5 ± 0.08, P = 0.005). Endurance time and heart rate at peak exercise were significantly lower in patients with LQTS compared with controls (11 ± 0.5 vs 15 ± 0.5 minutes, P < 0.0001; 169 ± 5 vs 198 ± 2 beats per minute, P < 0.0001). Conclusions: Despite guideline recommendations restricting PA, risk of sudden cardiac death, and use of beta-blockers, our cohort of patients with LQTS reported similar PA levels as healthy controls.

Contexte: L'activité physique est importante pour la santé cardiovasculaire ainsi que le bien-être social et émotionnel des enfants. Chez les patients qui présentent un syndrome du QT long (SQTL), l'activité physique est souvent restreinte, et des bêta-bloquants sont fréquemment prescrits pour la maîtrise de la maladie. L'objectif de cette étude était de déterminer si le degré d'activité physique était inférieur chez les patients atteints du SQTL à celui de témoins en bonne santé. Méthodologie: Des patients atteints du SQTL d'une clinique d'arythmie héréditaire ont rempli le questionnaire sur l'activité physique pour les enfants et les adolescents (PAQ-C/A, pour Physical Activity Questionnaire for Children and Adolescents) et subi une épreuve d'effort. Le score du PAQ (mesure générale de l'activité physique pour les jeunes, sans unité) et le temps d'endurance ont été comparés à ceux obtenus chez des témoins en bonne santé. Résultats: Vingt-trois patients atteints du SQTL ont rempli le PAQ et, dans l'année suivante, subi une épreuve d'effort. Pour ce qui est du score du PAQ, aucune différence n'a été observée entre le groupe atteint du SQTL et le groupe témoin (2,3 ± 0,15 chez les patients atteints du SQTL vs 2,3 ± 0,18 chez les témoins; p = 0,78). L'âge était sans effet sur l'activité physique chez les patients atteints du SQTL (p > 0,05), tandis que le degré d'activité physique diminuait significativement avec l'âge chez les témoins (p. ex. 3,2 ± 0,07 chez les témoins de 11 à 12 ans vs 1,5 ± 0,08 chez les témoins de 17 à 20 ans, p = 0,005). Pendant l'effort maximal, le temps d'endurance était significativement plus court et la fréquence cardiaque, significativement plus basse chez les patients atteints du SQTL que chez les témoins (11 ± 0,5 vs 15 ± 0,5 minutes, p < 0,0001; 169 ± 5 vs 198 ± 2 battements par minute, p < 0,0001). Conclusions: Malgré la restriction de l'activité physique recommandée par les lignes directrices, le risque de mort subite d'origine cardiaque et l'utilisation de bêta-bloquants, dans notre cohorte de patients atteints du SQTL, le degré d'activité physique a été semblable à celui des témoins en bonne santé.

Whole blood human transcriptome and virome analysis of ME/CFS patients experiencing post-exertional malaise following cardiopulmonary exercise testing.

Myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS) is a syndrome of unknown etiology characterized by profound fatigue exacerbated by physical activity, also known as post-exertional malaise (PEM). Previously, we did not detect evidence of immune dysregulation or virus reactivation outside of PEM periods. Here we sought to determine whether cardiopulmonary exercise stress testing of ME/CFS patients could trigger such changes. ME/CFS patients (n = 14) and matched sedentary controls (n = 11) were subjected to cardiopulmonary exercise on 2 consecutive days and followed up to 7 days post-exercise, and longitudinal whole blood samples analyzed by RNA-seq. Although ME/CFS patients showed significant worsening of symptoms following exercise versus controls, with 8 of 14 ME/CFS patients showing reduced oxygen consumption ([Formula: see text]) on day 2, transcriptome analysis yielded only 6 differentially expressed gene (DEG) candidates when comparing ME/CFS patients to controls across all time points. None of the DEGs were related to immune signaling, and no DEGs were found in ME/CFS patients before and after exercise. Virome composition (P = 0.746 by chi-square test) and number of viral reads (P = 0.098 by paired t-test) were not significantly associated with PEM. These observations do not support transcriptionally-mediated immune cell dysregulation or viral reactivation in ME/CFS patients during symptomatic PEM episodes.
