Introduction: Coronavirus disease 2019 (COVID‐19) emerged in China, leading to worldwide morbidity and mortality, including depression and anxiety. As the pandemic spread throughout Italy, mental health concerns increased for people with cystic fibrosis (pwCF), who are at greater risk. The aim was to pilot a Telehealth Psychological Support Intervention for pwCF and caregivers to reduce stress, depression, and anxiety during the lockdown in Italy in March 2020.Methods: This intervention utilized cognitive behavioral skills (e.g., cognitive reframing). Participants included 16 pwCF and 14 parents, who completed four individual telehealth sessions with a psychologist. Stress ratings, Patient Health Questionnaire and General Anxiety Disorder, PHQ‐8 and GAD‐7, were completed, in addition to Feasibility and Satisfaction ratings.Results: Ratings of stress significantly decreased from pre‐ to post‐testing for pwCF (paired t(14) = −4.06, p < .01) and parents (paired t = −5.2, p < .001). A large percentage of both groups scored in the clinical range for depression and anxiety at baseline (pwCF: depression/anxiety = 71%; parents: depression = 57%; anxiety = 79%); a large proportion (20%–40%) reported moderate to severe symptomatology. Significant reductions in depression for pwCF were found (pre: M = 8.0 to post: M = 4.7; paired t(14) = 2.8, p < .05) but not anxiety (pre: M = 6.9 to post: M = 5.6, t(14) = 1.2, p = NS—non‐significant). Parental depression decreased for parents (pre: M = 6.4 to post: M = 5.1, t(14) = −2.5, p < .05), but not anxiety (pre: M = 8.1 to post: M = 7.9, t(14) = −0.2, p = NS). Feasibility and Satisfaction were positive.Conclusion: This telehealth intervention yielded reductions in stress and depression for participants. Anxiety did not significantly decrease, possibly because COVID was ongoing. This feasible, satisfactory intervention was effective for improving mental health.

Elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) was shown to be safe and efficacious in people with cystic fibrosis (CF) heterozygous for F508del and a minimal function mutation (F/MF) or homozygous for F508del (F/F) in two pivotal Phase 3 trials, significantly improving percentage predicted forced expiratory volume in 1 second, Cystic Fibrosis Questionnaire-Revised, Respiratory Domain (CFQ-R RD) scores, and sweat chloride concentration. Here, we analyzed the 11 non-respiratory domains (non-RDs) of the CFQ-R, which assess general health-related quality of life (i.e., Physical Functioning, Role Functioning, Vitality, Health Perceptions, Emotional Functioning, and Social Functioning) and quality of life impacted by CF (i.e., Body Image, Eating Problems, Treatment Burden, Weight, and Digestive Symptoms), for participants in these two Phase 3 trials. ELX/TEZ/IVA treatment led to higher scores in all CFQ-R non-RDs, with improvements in most domains compared with control treatments. These findings demonstrate that ELX/TEZ/IVA improves a range of CF-specific symptoms and general functioning and well-being.

Objective: To evaluate the longitudinal effects of cochlear implantation (CIs) on young, deaf children's social competence over 5 years of implant use and compare their social skills to those of same-aged, hearing peers. Study Design: Prospective, longitudinal between- and within-subjects design, with assessments completed 3 times over 5 years. Setting: This study was conducted at 6 cochlear implant centers and two preschools that enrolled both CI and hearing children. Patients: Parents of 132 children with CIs and 67 age-matched hearing controls completed the study measures. Children were between 5 and 9 years of age at the first time point. Interventions: Cochlear implantation and speech-language therapy. Main Outcome Measures: Three subscales were drawn from 2 standardized measures of behavioral and social functioning, the Behavioral Assessment Scale for Children (Adaptability, Social Skills) and the Social Skills Rating System (Social Skills). A latent social competence variable was created using multiple subscales, which was modeled over time. Results: Parent data indicated that children with CIs were delayed in comparison to their hearing peers on the social competence latent variable across all time points. Further, there was minimal evidence of “catch-up” growth over this 5-year period. Conclusion: Children with CIs continued to experience delays in social competence after several years of implant use. Despite documented gains in oral language, deficits in social competence remained. To date, no interventions for children with CIs have targeted these social and behavioral skills. Thus, interventions that address the functioning of the “whole child” following cochlear implantation are needed.
