RESUMEN
BACKGROUND: Generalized anxiety disorder (GAD) is a prevalent anxiety disorder characterized by uncontrollable worry, trouble sleeping, muscle tension, and irritability. Cognitive behavioural therapy (CBT) is one of the first-line treatments that has demonstrated high efficacy in reducing symptoms of anxiety. Electronically delivered CBT (e-CBT) has been a promising adaptation of in-person treatment, showing comparable efficacy with increased accessibility and scalability. Finding further scalable interventions that can offer benefits to patients requiring less intensive interventions can allow for better resource allocation. Some studies have indicated that weekly check-ins can also lead to improvements in GAD symptoms. However, there is a lack of research exploring the potential benefits of online check-ins for patients with GAD. OBJECTIVE: This study aims to investigate the effects of weekly online asynchronous check-ins on patients diagnosed with GAD and compare it with a group receiving e-CBT. METHODS: Participants (n e-CBT = 45; n check-in = 51) with GAD were randomized into either an e-CBT or a mental health check-in program for 12 weeks. Participants in the e-CBT program completed pre-designed modules and homework assignments through a secure online delivery platform where they received personalized feedback from a trained care provider. Participants in the mental health check-in condition had weekly asynchronous messaging communication with a care provider where they were asked structured questions with a different weekly theme to encourage conversation. RESULTS: Both treatments demonstrated statistically significant reductions in GAD-7-item questionnaire (GAD-7) scores over time, but when comparing the groups there was no significant difference between the treatments. The number of participants who dropped out and baseline scores on all questionnaires were comparable for both groups. CONCLUSIONS: The findings support the effectiveness of e-CBT and mental health check-ins for the treatment of GAD. PLAIN LANGUAGE SUMMARY TITLE: Comparing the Effectiveness of Electronically Delivered Therapy (e-CBT) to Weekly Online Mental Health Check-ins for Generalized Anxiety Disorder-A Randomized Controlled Trial.
Generalized anxiety disorder (GAD) is a prevalent psychiatric condition that leads to symptoms like uncontrollable worry, trouble sleeping, muscle tension, and irritability. Cognitive behavioural therapy (CBT) is a common psychotherapy used for GAD since it has been shown to reduce symptoms. However, traditional CBT that is in person can have barriers such as being inaccessible and costly, and therefore electronically delivered CBT (e-CBT) is a viable alternative since previous studies have shown its efficacy in reducing symptoms and being similar compared to face-to-face CBT. Previous studies have also shown reductions in GAD symptomology through the use of checking in on people and their mental health. Therefore, this study aimed to compare e-CBT to a check-in condition and had a total of 45 individuals in e-CBT and 51 participants in the check-in condition. Participants in the e-CBT condition completed 12 weeks of predesigned e-CBT modules, homework and received personalized feedback from a care provider. In contrast, individuals in the check-in condition completed 12 weeks of unstructured asynchronous messaging with a care provider. Results from the study showed that both the e-CBT and check-in condition demonstrated statistically significant improvements in GAD-7 across time, but when comparing the groups there was no significant difference. The results show the efficacy of e-CBT and checking in on people's mental health to reduce GAD and future research should examine the 2 conditions combined.

BACKGROUND: Trials have not directly compared biologics for the treatment of asthma. OBJECTIVE: To compare the relative efficacy of biologics in asthma. METHODS: We searched MEDLINE, EMBASE, CENTRAL, and clinicaltrials.gov from inception to May 31, 2022 for randomized trials addressing biologic therapies for asthma. Reviewers worked independently and in duplicate to screen references, extract data, and assess risk of bias. We performed a frequentist network meta-analysis and assessed the certainty of evidence using the Grading of Recommendations, Assessment, Development, and Evaluations approach. We present dichotomous outcomes as absolute risk differences per 1000 patients and relative risk with 95% confidence intervals (95% CI) and continuous outcomes as mean difference (MD) and 95% CI. RESULTS: We identified 64 trials, including 26,630 patients. For patients with eosinophilic asthma, tezepelumab (329 fewer exacerbations per 1000 [95% CI, 272.6-366.6 fewer]) and dupilumab (319.6 fewer exacerbations per 1000 [95% CI, 272.6-357.2 fewer]) reduce exacerbations compared with placebo (high certainty). Tezepelumab (MD, 0.24 L [95% CI, 0.16-0.32]) and dupilumab (0.25 L [95% CI, 0.21-0.29]) improve lung function compared with placebo (high certainty). Both tezepelumab (110.97 fewer hospital admissions per 1000 [95% CI, 94.53-120.56 fewer]) and dupilumab (97.27 fewer hospitalizations [4.11-124.67 fewer]) probably reduce hospital admissions compared with placebo (moderate certainty). For patients with low eosinophils, biologics probably do not improve asthma outcomes. For these patients, tezepelumab (MD, 0.1 L [95% CI, 0-0.19]) and dupilumab (MD, 0.1 L [95% CI, 0-0.20]) may improve lung function (low certainty). CONCLUSION: Tezepelumab and dupilumab are effective at reducing exacerbations. For patients with low eosinophils, however, clinicians should probably be more judicious in using biologics, including tezepelumab, because they probably do not confer substantial benefit.
