Abstract Background Various service provision models for youth at risk of homelessness have been researched and implemented, including access to housing and physical and mental health resources. However, even with these interventions, we remain unaware of how best to manage symptoms of depression and anxiety and the rate of drug use in these populations primarily because of a lack of feasibility data. Methods This paper presents the results of a mixed-methods study in London, Canada, that examined the feasibility of implementing a biopsychosocial intervention, SKY Schools, in at-risk youth aged between 16 and 25 (n = 49). The study also recorded qualitative responses about the program’s usefulness from the perspective of the service users. The SKY Schools intervention consisted of social-emotional learning combined with Sudarshan Kriya Yoga, a standardized yoga-based breathing exercise routine. The intervention program was divided into two phases: an active learning phase and a reinforcement phase. The following feasibility outcome measures were collected: (1) the number of potential participants approached per month, (2) number (proportion) who were successfully screened, (3) the proportion of screened participants who enrolled, (4) the rate of retention in the study, (5) rate of adherence to study protocol, (6) proportion of planned ratings that were completed, (7) intervention cost per case, (8) completeness of final data for analysis, (9) length of time to collect all data, (10) quality of all collected data, (11) determining if partnering community organizations were willing to conduct the study as per study protocol, (12) determining if there were any capacity issues with partners providing intervention and investigators being able to perform the tasks that they were committed to doing, (13) determining if there were any problems of entering the data into a computer, (14) preliminary data about the safety of the intervention, and (15) preliminary estimate of treatment effects. Results All feasibility outcome measures were collectible. In the city of London, Canada it was feasible to conduct a pilot study in this population of youth at risk of homelessness. Foremost among the findings was a high retention rate (61.2%) and overall positive qualitative feedback with a number of potential suggestions to improve the delivery and quality of the intervention. However, we had a significantly low recruitment rate (0.27 participants per week) suggesting that multiple sites will be needed to achieve an adequate sample size for a subsequent definitive trial. Conclusions Future researchers may consider the findings of this feasibility study when designing a randomized control trial to further assess the efficacy and tolerability of SKY Schools.

Abstract The pharmacological treatment of depression consists of stages of trial and error, with less than 40% of patients achieving remission during first medication trial. However, in a large, randomized-controlled trial (RCT) in the U.S. (“GUIDED”), significant improvements in response and remission rates were observed in patients who received treatment guided by combinatorial pharmacogenomic testing, compared to treatment-as-usual (TAU). Here we present results from the Canadian “GAPP-MDD” RCT. This 52-week, 3-arm, multi-center, participant- and rater-blinded RCT evaluated clinical outcomes among patients with depression whose treatment was guided by combinatorial pharmacogenomic testing compared to TAU. The primary outcome was symptom improvement (change in 17-item Hamilton Depression Rating Scale, HAM-D17) at week 8. Secondary outcomes included response (≥50% decrease in HAM-D17) and remission (HAM-D17 ≤ 7) at week 8. Numerically, patients in the guided-care arm had greater symptom improvement (27.6% versus 22.7%), response (30.3% versus 22.7%), and remission rates (15.7% versus 8.3%) compared to TAU, although these differences were not statistically significant. Given that the GAPP-MDD trial was ultimately underpowered to detect statistically significant differences in patient outcomes, it was assessed in parallel with the larger GUIDED RCT. We observed that relative improvements in response and remission rates were consistent between the GAPP-MDD (33.0% response, 89.0% remission) and GUIDED (31.0% response, 51.0% remission) trials. Together with GUIDED, the results from the GAPP-MDD trial indicate that combinatorial pharmacogenomic testing can be an effective tool to help guide depression treatment in the context of the Canadian healthcare setting (ClinicalTrials.gov NCT02466477).

To optimize outcomes in Late-Life Depression (LLD), there remains a need for innovative augmentation treatments. Problem-Solving Therapy (PST) is demonstrated as an effective augmentation psychotherapy for LLD in a one-to-one setting. This study investigated the feasibility of implementing Case Manager delivered group PST for LLD in a community setting. The design was a mixed-methods pilot one-group pre-test post-test quasi-experimental feasibility study in adults aged 60+ years meeting criteria for major depressive disorder (MDD). Feasibility measures were inclusion, attendance, and attrition rate. PST was delivered in groups of 6–9 participants over 8 weeks. Participants completed a weekly self-rated depression scale from weeks 1–8, and pre-and post-intervention rater assessed depression and self-rated assessments of quality of life, insomnia, disability, and anxiety. Focus group interviews took place at week 8 for the first and last study cohort. Twenty-nine participants (inclusion rate of 91%) were enrolled, a recruitment rate of 2.2 participants/month. Of these, 26 (90%) completed week 8 assessments and 25 (96%) attended 5 or more PST sessions, while 15 (58%) attended all sessions. Self-rated depression, anxiety, and insomnia scores decreased significantly with medium-to-large effect sizes, while there was non-significant improvement in rater-assessed depression and self-rated disability and quality of life. Qualitative data showed participants found PST an easy-to-use technique and felt empowered and hopeful in recovering from depression. The results justify a replication of the study in a large RCT exploring the efficacy of offering a group-based Case Manager facilitated PST to older adults with LLD, in a community setting.

Abstract Background Despite the high prevalence of comorbid chronic pain and depression, this comorbidity remains understudied. Meditation has demonstrated efficacy for both chronic pain and depression independently, yet there have been few studies examining its effectiveness when both conditions are present concurrently. Furthermore, while meditation is generally accepted as a safe and effective health intervention, little is known about how to implement meditation programs within or alongside the health care system. Methods We will conduct a hybrid type 1 effectiveness–implementation evaluation. To measure effectiveness, we will conduct a randomized controlled trial comparing Sahaj Samadhi Meditation and the Health Enhancement Program in 160 people living with chronic pain, clinically significant depressive symptoms, and on long-term opioid therapy. Changes in depressive symptoms will be our primary outcome; pain severity, pain-related function, opioid use, and quality of life will be the secondary outcomes. The primary end point will be at 12 weeks with a secondary end point at 24 weeks to measure the sustainability of acute effects. Patients will be recruited from a community-based chronic pain clinic in a large urban center in Mississauga, Canada. The meditation program will be delivered in the clinical environment where patients normally receive their chronic pain care by certified meditation teachers who are not regulated health care providers. We will use a mixed-methods design using the multi-level framework to understand the implementation of this particular co-location model. Discussion Results of this hybrid evaluation will add important knowledge about the effectiveness of meditation for managing depressive symptoms in people with chronic pain. The implementation evaluation will inform both effectiveness outcomes and future program development, scalability, and sustainability. Trial registration ClinicalTrials.gov: NCT04039568 .

Abstract Objectives Objective 1: To determine if it is feasible to conduct an RCT of online Sudarshan Kriya Yoga (SKY) for frontline hospital and long-term care home staff under the constraints imposed by the COVID-19 pandemic and need for remote trial monitoring. Objective 2: To assess whether online versions of SKY and/or Health Enhancement Program (HEP) result in improvement in self-rated measures of insomnia, anxiety, depression, and resilience. Trial design This is an open-label feasibility randomized controlled trial (RCT), comparing an online breath based yogic intervention SKY versus an online control mind-body intervention HEP in frontline hospital and long-term care home staff managing the COVID-19 pandemic. Participants Participants will include frontline hospital and long-term care home staff that are involved in the management of COVID-19 patients in London, Ontario, Canada. Participants will be willing and able to attend via online video conferencing software to participate in the study interventions. Participants must have an adequate understanding of English and be able to sit without physical discomfort for 60 minutes. Intervention and comparator Sudarshan Kriya Yoga (SKY): The online version of SKY will be delivered by at least one certified Canadian SKY teacher, with at least one back up teacher at all times, under the supervision of Ms. Ronnie Newman, Director of Research and Health Promotion, Art of Living Foundation, USA. The online version of SKY for healthcare workers has a total duration of 3 hours. Phase I will consist of 5 self-paced online modules of 4-10 minutes each to learn the breath control techniques. Participants will be sent an online survey in REDCap requesting that they self-confirm completion of the Phase I modules. In Phase II, 2 interactive online sessions of 1 hour each will be held on consecutive days with a certified SKY teacher, during which participants will learn the fast, medium and slow breaths. For ease of scheduling, multiple time windows will be offered for Phase II. There will be at least one back up teacher at all times. Both Phase I and II will be completed in the first week. Health Enhancement Program (HEP): The active control arm, HEP, will consist of time-matched online self-paced modules for Phase I. Phase II will consist of mindfulness-based meditation sessions delivered by mental health staff. HEP will be an active treatment program that incorporates mind-body interventions. HEP will consist of time-matched online self-paced modules with psychoeducation on healthy active living as well as interactive modules comprising of guided de-stressing exercises including music therapy, mindfulness and progressive muscle relaxation. Weekly follow up sessions will be offered to all recruited participants for 30 minutes each for the subsequent 4 weeks in both study arms. Main outcomes The following feasibility outcomes will be measured at the end of the study: (1) rate of participant recruitment, (2) rate of retention, (3) completeness of data entry, (4) cost of interventions, and (5) unexpected costs. Such measures will be collected on a daily basis through-out the study and tabulated 5 weeks later at the end of the study. Randomisation Participants will be randomized after they have electronically signed the consent form and the research staff have confirmed eligibility. We will use REDCap to perform randomization in a 1:1 ratio as well as allocation concealment. REDCap is widely used by health researchers worldwide to significantly reduce data entry and study management errors to improve data fidelity. Blinding (masking) All study participants will be blinded to the study hypotheses so as to prevent any expectation bias. Group allocation will be masked during analysis. Numbers to be randomised (sample size) This study will randomize a total of 60 participants in a 1:1 ratio to either SKY or HEP interventions. Trial Status Protocol version number 2.0 (June 5, 2020). Recruitment is currently ongoing (starting June 25, 2020). We anticipate to complete recruitment by June 30, 2021 and complete the study by September 30, 2021. Trial registration ClinicalTrials.gov protocol ID NCT04368676 (posted April 30, 2020).

Abstract Background Recent estimates suggest an 11% prevalence of current late-life depression (LLD) and a lifetime prevalence of 16–20%. LLD leads to cognitive disturbance as well as a nearly two to three times increased risk of dementia. We conducted a recent randomized controlled trial (RCT) which demonstrated that Sahaj Samadhi meditation (SSM), an easy-to-implement, meditation-based augmentation strategy, led to higher rates of symptom remission when compared to treatment as usual (40.0 vs 16.3%; odds ratio, 3.36; 95% CI 1.06–10.64; p = 0.040). Here we present a protocol describing a two-site, blinded, RCT, comparing an SSM arm to an active-control arm – a Health Enhancement Program (HEP) intervention – in their ability to reduce depressive symptoms and improve executive functioning, among several other exploratory outcomes. Methods/design One hundred and ninety-two (n = 192) participants with LLD will be recruited at two sites (London, ON, Canada, and Montreal, QC, Canada). Participants will undergo stratified randomization with regards to site and the presence of treatment-resistant-LLD (TR-LLD) or not, to either SSM or HEP. We will assess change in (1) depression severity using the Hamilton Depression Rating Scale (HAM-D), (2) executive functioning, and (3) other exploratory physiological and mood-based measures, at baseline (0 weeks), post intervention (12 weeks), and 26 weeks after baseline. Raters, clinicians, and care providers will be blinded to group allocation while participants will be blinded to the study hypotheses. Discussion This study should more definitively assess whether SSM can be used as an augmentation strategy in routine clinical care for patients suffering from LLD and TR-LLD. If the effects of SSM are significantly better than HEP, it will offer support for the routine use of this intervention to manage LLD/TR-LLD and comorbid declines in executive dysfunction. The results of this study could also inform whether SSM can improve/prevent cognitive decline in LLD. Trial registration ClinicalTrials.gov, ID: NCT03564041. Registered on 20 June 2018.

Parents of children with inborn errors of metabolism (IEM) face numerous psychosocial challenges. An increased understanding and awareness of these stressors can ensure better overall outcomes for the entire family. We conducted semi-structured, in-person interviews with ten parents to identify psychosocial stressors, strategies, and supports they utilized to overcome their challenges. Our interview guide was designed to elicit familial experiences during the pre- and post-diagnosis periods. The themes and sub-themes were identified through qualitative descriptive textual analysis of audio-recorded transcripts. Major themes identified include ambiguity of illness, changing family and spousal dynamics, and navigating the healthcare system. Sub-themes revolved around disease effects, psychological stressors, health systems, support, and facing the disease. Healthcare professionals have an opportunity to minimize the impact of negative emotional outcomes by assisting families as they navigate the experience of having a child with an IEM. Our findings can be used to develop and continue a more well-rounded, family-oriented framework for IEM management.

Abstract Background Physical exercise, cognitive training, and vitamin D are low cost interventions that have the potential to enhance cognitive function and mobility in older adults, especially in pre-dementia states such as Mild Cognitive Impairment (MCI). Aerobic and progressive resistance exercises have benefits to cognitive performance, though evidence is somewhat inconsistent. We postulate that combined aerobic exercise (AE) and progressive resistance training (RT) (combined exercise) will have a better effect on cognition than a balance and toning control (BAT) intervention in older adults with MCI. We also expect that adding cognitive training and vitamin D supplementation to the combined exercise, as a multimodal intervention, will have synergistic efficacy. Methods The SYNERGIC trial (SYNchronizing Exercises, Remedies in GaIt and Cognition) is a multi-site, double-blinded, five-arm, controlled trial that assesses the potential synergic effect of combined AE and RT on cognition and mobility, with and without cognitive training and vitamin D supplementation in older adults with MCI. Two-hundred participants with MCI aged 60 to 85 years old will be randomized to one of five arms, four of which include combined exercise plus combinations of dual-task cognitive training (real vs. sham) and vitamin D supplementation (3 × 10,000 IU/wk. vs. placebo) in a quasi-factorial design, and one arm which receives all control interventions. The primary outcome measure is the ADAS-Cog (13 and plus modalities) measured at baseline and at 6 months of follow-up. Secondary outcomes include neuroimaging, neuro-cognitive performance, gait and mobility performance, and serum biomarkers of inflammation (C reactive protein and interleukin 6), neuroplasticity (brain-derived neurotropic factor), endothelial markers (vascular endothelial growth factor 1), and vitamin D serum levels. Discussion The SYNERGIC Trial will establish the efficacy and feasibility of a multimodal intervention to improve cognitive performance and mobility outcomes in MCI. These interventions may contribute to new approaches to stabilize and reverse cognitive-mobility decline in older individuals with MCI.

Late-life depression affects 2–6% of seniors aged 60 years and above. Patients are increasingly embracing non-pharmacological therapies, many of which have not been scientifically evaluated. This study aimed to evaluate a category of meditation, automatic self-transcending meditation (ASTM), in alleviating symptoms of depression when augmenting treatment as usual (NCT02149810). The preliminary results of an ongoing single-blind randomised controlled trial comparing a training programme involving ASTM with a wait-list control indicate that a 12-week ASTM programme may lead to significantly greater reductions in depression and anxiety severity. As such, ASTM may be an effective adjunctive therapy in the treatment of late-life depression.

The risk of ventricular arrhythmia with citalopram and escitalopram is controversial. In this study we investigated the association between these two drugs and the risk of ventricular arrhythmia.We conducted a population-based retrospective cohort study of older adults (mean age 76 years) from 2002 to 2012 in Ontario, Canada, newly prescribed citalopram (n = 137 701) or escitalopram (n = 38 436), compared to those prescribed referent antidepressants sertraline or paroxetine (n = 96 620). After inverse probability of treatment weighting using a propensity score, the baseline characteristics of the comparison groups were similar. The primary outcome was a hospital encounter with ventricular arrhythmia within 90 days of a new prescription, assessed using hospital diagnostic codes. The secondary outcome was all-cause mortality within 90 days.Citalopram was associated with a higher risk of a hospital encounter with ventricular arrhythmia compared with referent antidepressants (0.06% vs. 0.04%, relative risk [RR] 1.53, 95% confidence intervals [CI]1.03 to 2.29), and a higher risk of mortality (3.49% vs. 3.12%, RR 1.12, 95% CI 1.06 to 1.18). Escitalopram was not associated with a higher risk of ventricular arrhythmia compared with the referent antidepressants (0.03% vs. 0.04%, RR 0.84, 95% CI 0.42 to 1.68), but was associated with a higher risk of mortality (2.86% vs. 2.63%, RR 1.09, 95% CI 1.01 to 1.18).Among older adults, initiation of citalopram compared to two referent antidepressants was associated with a small but statistically significant increase in the 90-day risk of a hospital encounter for ventricular arrhythmia.

Delirious mania has been well recognized in the published literature and in the clinic. Over the years there has been refinement of understanding of its clinical features, course, and treatment. The literature suggests that delirious mania should be considered in individuals who present with a constellation of sudden onset delirium, mania, and psychosis. However, delirious mania is not recognized under a formal classification system nor are there any formal guidelines for its treatment. We, as such, question if the concept of delirious mania in the elderly is valid. We present a case of an elderly man with marked features of delirium with minimal manic or psychotic features who had a previous diagnosis of bipolar I disorder. On thorough clinical assessments no identifiable cause of his delirium was found. We therefore considered his presentation to be more likely due to delirious mania. Electroconvulsive therapy was considered and offered to which he responded very well. We invite the reader to consider whether delirious mania is a valid concept in the elderly, where features of delirium may be more prominent than manic or psychotic features.

La oxcarbazepina, un cetoderivado del “estabilizador del estado de ánimo” carbamazepina, puede ser efectiva en el tratamiento de los episodios agudos del trastorno bipolar. Potencialmente, puede ofrecer ventajas farmacocinéticas sobre la carbamazepina. Objetivos: Revisar la eficacia y la aceptabilidad de la oxcarbazepina en comparación con el placebo y otros agentes en el tratamiento de los episodios agudos del trastorno bipolar, como manía, episodios mixtos y depresión. Métodos de búsqueda: Se realizaron búsquedas en las bases de datos electrónicas hasta el 2 de sepiembre 2011. Se realizaron búsquedas manuales en revistas especializadas y resúmenes de congresos. Se estableció contacto con autores, expertos en el tema y compañías farmacéuticas para solicitar información sobre ensayos publicados o no publicados. Criterios de selección: Ensayos controlados con asignación aleatoria (ECAs) que compararon la oxcarbazepina con el placebo o agentes alternativos, donde la intención declarada de la intervención fue buscar el tratamiento agudo para el trastorno afectivo bipolar. Se incluyeron participantes con trastorno bipolar, hombres y mujeres, de todas las edades. Obtención y análisis de los datos: Dos revisores extrajeron los datos de los informes originales individualmente. Para los datos dicotómicos, se calcularon los odds ratios (OR) con intervalos de confianza (IC) del 95%. Los datos continuos se analizaron mediante las diferencias de medias estandarizadas (con IC del 95%). Resultados principales: Siete estudios se incluyeron en el análisis (368 participantes en total). Todos los pacientes presentaban manía, hipomanía, episodios mixtos o trastorno de ciclo rápido. En general, su calidad metodológica era relativamente baja. No hubo diferencias en el análisis de la medida de resultado primaria (una caída del 50% o más en la Young Mania Rating Scale [YMRS]) entre la oxcarbazepina y el placebo (N=1, n=110; OR 2,10, IC del 95%: 0,94 a 4,73) en un estudio que se realizó en niños; no había estudios disponibles en participantes adultos. En comparación con otros estabilizadores del estado de ánimo, no hubo diferencias entre la oxcarbazepina y el valproato como agente antimaníaco según la medida de resultado primaria (caída del 50% o más en la YMRS; OR 0,44, IC del 95%: 0,10 a 1,97; 1 estudio, n=60; p=0,273) o la medida de resultado secundaria (diferencias en la YMRS entre los dos grupos; DME 0,18, IC del 95%: -0,24 a 0,59; 2 estudios, n=90; ρ=0,40). No se encontró ninguna medida de resultado primaria o secundaria de la eficacia que comparara la oxcarbazepina con la monoterapia con litio. Como tratamiento complementario del litio, la oxcarbazepina redujo las puntuaciones en las escalas de calificación de depresión más que la carbamazepina en un grupo de participantes maníacos en la Montgomery-Âsberg Depression Rating Scale (MADRS) (DME - 1,12, IC del 95%: -1,71 a -0,53; 1 estudio, n=52; p=0,0002) y en la Hamilton Depression Rating Scale (HDRS) (DME - 0,77, IC del 95%: -1,35 a -0,20; 1 estudio, n=52; p=0,008). Hubo una incidencia mayor de efectos adversos, particularmente neuropsiquiátricos en los participantes asignados al azar a la oxcarbazepina en comparación con los asignados al placebo (1 estudio, n=115, 17% a 39% de participantes con oxcarbazepina tuvo al menos uno de estos eventos en comparación con 7% a 10% que recibieron placebo). No hubo ninguna diferencia en las tasas de eventos adversos entre la oxcarbazepina y otros estabilizadores del estado de ánimo o el haloperidol. Conclusiones de los autores: Actualmente, hay ensayos insuficientes de calidad metodológica adecuada sobre la oxcarbazepina en el tratamiento agudo del trastorno bipolar para informar sobre su eficacia y aceptabilidad. Los estudios examinan predominantemente el tratamiento de la manía: hay datos a partir del análisis de subgrupos sobre estados de ciclos rápidos, hipomanía y episodios afectivos mixtos. De los pocos estudios incluidos en esta revisión, la oxcarbazepina no difirió en la eficacia en comparación con el placebo en niños y adolescentes. No fue diferente de otros agentes activos en adultos. Puede tener un perfil de tolerabilidad más deficiente en comparación con el placebo. No se encontraron datos sobre las medidas de resultado relevantes para los pacientes y los médicos, como la duración de la hospitalización. Se necesitan ensayos controlados con asignación aleatoria con adecuado poder estadístico y de buena calidad metodológica para informar el potencial terapéutico de la oxcarbazepina a través del espectro de episodios agudos en el trastorno bipolar.
