Brief Internet-delivered Intervention for Children and Adolescents With Anxiety and Depression Symptoms...
Childhood Anxiety DisorderChildhood DepressionInvestigators developed a brief standardized internet-delivered cognitive-behavioral program for treating anxious and depressive symptoms in children and adolescents in the context of COVID-19 pandemics in Brazil. A 2-arm parallel-randomized controlled clinical trial will be conducted to test the efficacy of this program (intervention group), in comparison with a educational-only intervention program based on videos (active control group). 280 children and adolescents (8 to 17 years-old) with clinically significant anxious and/or depressive symptoms will be recruited through internet and social media. They will be randomized either to the intervention (n=140) or active control group (n=140). Participants will be recruited from across the country. The therapeutic program consists of 5 weekly sessions covering the following contents: education on stress reactions, family communication, relaxation and mindful techniques, emotion recognition, management of irritability, behavioral activation, and cognitive restructuring. The educational program consists of 15 videos covering the same content. Participants in the intervention group will also have access to these videos. Both child/adolescent and at least one caregiver will be required to take part in the sessions (and watch the videos). Participants will be assessed at the beginning (baseline; T0) at the end (endpoint; T1), and 30 days after the intervention (follow-up; T2) with standardized questionnaires, through an interview with a blinded investigator. Participants that develop severe symptomatology requiring further support during the intervention (such as psychiatric pharmacological treatment and/or more intensive psychotherapy) will be referred to adequate treatment. During the week prior to the intervention and the first week after its end, adolescents (older than 12 years-old) in both groups with access to a smartphone will be asked to report their momentary mood, emotions, and stress several times a day using the same smartphone app that will deliver the educational content to both groups. Adolescents will also be asked to install a second smartphone application that captures data from the phone sensors to provide proxies on behaviors associated with depression, such as social isolation (by the proximity with other devices, time spent on social media, as well as environmental sound and light) amount of inactivity (by assessing the maximum distance traveled throughout the day), among others.

Decentering and Relapse/Recurrence in MBCT for Depression in Adults
DepressionDepressive Disorder2 moreObjective: "Decentering" is defined as the ability to observe one's thoughts and feelings as temporary, objective events in the mind, and is increasingly regarded as a candidate mechanism in mindfulness-based interventions. The current study sought to examine the role of decentering, and other related variables, in the efficacy of Mindfulness-based cognitive therapy (MBCT) as compared to two active comparison conditions. Method: Formerly depressed individuals (N = 227), randomly assigned to MBCT (n = 74), relaxation group therapy (RGT; n = 77) or treatment-as-usual (TAU; n = 76), completed self-report measures of decentering and symptoms of depression at pre-, mid-, and post-treatment, and relapse was assessed at 3, 6, 9, and 12 months, post-treatment.

Optimal Timing and Failure Prediction of High Flow Nasal Cannula Oxygen Therapy in Emergency Department:...
Respiratory InsufficiencyAcute Hypercapnic Respiratory Failure8 moreThis study targets adult patients treated with high flow nasal cannula (HFNC) at emergency department (ED) of Severance hospital, Yonsei university. Patients with acute hypoxic respiratory failure presenting to the ED receive conventional oxygen therapy as initial treatment unless immediate endotracheal intubation is required. Partial rebreathing oxygen masks are mainly applied at first. If the patient's condition does not improve despite such treatment, the patient receives HFNC or endotracheal intubation. However, possible treatment range have not been studied, especially in ED. Decisions are made based on the personal experience of the medical staff in charge. Applying HFNC to patients who eventually fail can lead to delayed intubation and increased mortality. Failure prediction models such as ROX index and HACOR score have been developed due to such reasons. However, such models are mostly based on intensive care unit studies and after application of HFNC. Therefore, failure prediction model at the time before application of HFNC and efficacy of existing models in ED are necessary. This study is a prospective observational study and follows the standard treatment guidelines applied to the patient and the judgment of the attending physician during the patient's treatment process. Immediately before applying HFNC, the patient's respiratory rate, pulse rate, blood pressure, SpO₂, PaO₂, PaCO₂, GCS score are determined, and FiO₂ is measured above upper lips using oxygen analyzer(MaxO2+AE, Maxtec, USA). From these data, ROX index (SF ratio/respiratory rate), ROX-HR (ROX index/pulse rate), POX index (PF ratio/respiratory rate), POX-HR (POX index/pulse rate), and HACOR score (Heart Rate, Acidosis, Consciousness, Oxygenation, Respiratory rate) are calculated. The settings (flow rate, FiO₂, temperature) at the time of HFNC application are also measured. The same indices and HFNC settings are checked 30 minutes, 1 hour, 2 hours, 4 hours, 6 hours, and 12 hours after applying HFNC. Modified Borg score and comfort scale using 5-point Likert scale are additionally determined at 30 minutes for patient's comfort. Primary outcome is HFNC failure at 28 days, defined by endotracheal intubation. Other outcomes include intubation in ED and mortality at 28 and 90 days collected through phone interview. The receiver operating curve for ROX index, HACOR score, ROX-HR, and POX-HR at baseline, 30 minutes, 1 hour, 2 hours, 4 hours, 6 hours, and 12 hours are drawn for the outcomes. The area under the curve of the above indices are compared and cutoff values are chosen with maximum value of index J by the Youden's Index. A binary variable is created based on the cutoff values and multivariable logistic regression analyses are performed. Cutoff values for maximum specificity are also invested suggesting the lower limit of the indicator to which HFNC can be applied.

Examining the Effectiveness of Transdiagnostic, Internet-Delivered Cognitive Behaviour Therapy in...
DepressionPostpartum1 moreIn the proposed study, the investigators will examine the efficacy of transdiagnostic, Internet-delivered cognitive behaviour therapy (ICBT) in the treatment of postpartum anxiety and depression. Half of participants will receive the treatment immediately, and half of the participants will be assigned to a treatment-as-usual control condition. Participants assigned to the control condition will be offered the treatment after a 12-week waiting period, although data from this portion will not be included in the current study. All participants will complete questionnaires prior to the start of the treatment, following treatment (or corresponding 8-week waiting period), at 1-months follow-up (or corresponding 12-week waiting period), and at 6-months follow-up (in those assigned to the treatment condition). Further, those who receive the treatment will complete questionnaires on a weekly basis. The primary outcome measures include anxiety and depression. As part of the battery of questionnaires administered after the completion of the program, participants will be asked to rate the program content, the overall service, and their satisfaction with the program.

The investigators also hypothesized that acupuncture would be associated with minimal side effects.

Sleep-Disordered Breathing and PAP in Perinatal Depression
Sleep-disordered BreathingMajor Depressive DisorderThe goal of this study is to understand the contribution of sleep-disordered breathing (SDB) to one of the most common and debilitating adverse pregnancy outcomes, perinatal depression. The study is a randomized trial to test the efficacy of positive airway pressure (PAP) on sleep and depression symptoms in perinatal women. Participants will be pregnant women with depression and sleep-disordered breathing. Participants will be randomly assigned to receive either PAP therapy (PAP group) or treatment as usual within obstetrics (TAU group). Mood and sleep assessments will be completed at baseline, after 1 week of enrollment, and monthly thereafter through 12 weeks postpartum. Cortisol will be measured using saliva collection at baseline and again 8 weeks later.
