A brief CBT intervention for depersonalisation-derealisation disorder in psychosis: Results from a feasibility randomised controlled trial

BACKGROUND AND OBJECTIVES

Depersonalisation/derealisation symptoms are prevalent in psychosis patients, are associated with increased impairment, and may maintain psychosis symptoms. We aimed to establish the feasibility and acceptability of a brief, six session therapy protocol adapted from a Cognitive-Behavioural model of Depersonalisation-Derealisation Disorder (DDD) in participants with psychotic symptoms.

METHODS

A single-blind, randomised controlled trial was conducted with a treatment-as-usual control condition. Feasibility and acceptability estimates included rates of referral, acceptance, eligibility, consent, satisfaction and improved skills/knowledge to manage depersonalisation.

RESULTS

Twenty-one individuals were recruited to the trial. Results suggest that the intervention was feasible and acceptable to participants and there is some signal of effect on clinical outcomes.

LIMITATIONS

There were some challenges in recruitment. Recruitment feasibility estimates from the research register used may not be informative for future trials recruiting directly from teams.

CONCLUSIONS

Overall, the results suggest that further investigations would be of interest and recommendations for this are made.

Human prostate MRI at ultrahigh-performance gradient: A feasibility study

PURPOSE

To demonstrate the technical feasibility and the value of ultrahigh-performance gradient in imaging the prostate in a 3T MRI system.

METHODS

In this local institutional review board-approved study, prostate MRI was performed on 4 healthy men. Each subject was scanned in a prototype 3T MRI system with a 42-cm inner-diameter gradient coil that achieves a maximum gradient amplitude of 200 mT/m and slew rate of 500 T/m/s. PI-RADS V2.1-compliant axial T2 -weighted anatomical imaging and single-shot echo planar DWI at standard gradient of 70 mT/m and 150 T/m/s were obtained, followed by DWI at maximum performance (i.e., 200 mT/m and 500 T/m/s). In comparison to state-of-the-art clinical whole-body MRI systems, the high slew rate improved echo spacing from 1020 to 596 μs and, together with a high gradient amplitude for diffusion encoding, TE was reduced from 55 to 36 ms.

RESULTS

In all 4 subjects (waist circumference = 81-91 cm, age = 45-65 years), no peripheral nerve stimulation sensation was reported during DWI. Reduced image distortion in the posterior peripheral zone prostate gland and higher signal intensity, such as in the surrounding muscle of high-gradient DWI, were noted.

CONCLUSION

Human prostate MRI at simultaneously high gradient amplitude of 200 mT/m and slew rate of 500 T/m/s is feasible, demonstrating that improved gradient performance can address image distortion and T2 decay-induced SNR issues for in vivo prostate imaging.

The Effectiveness and Feasibility of Psychological Interventions for Populations Under Ongoing Threat: A Systematic Review

Current views of psychological therapies for trauma typically assume the traumatic event to be in the past. Yet, individuals who live in contexts of ongoing organized violence or experience intimate partner violence (IPV) may continue to be (re)exposed to related traumatic events or have realistic fears of their recurrence. This systematic review considers the effectiveness, feasibility, and adaptations of psychological interventions for individuals living with ongoing threat. PsychINFO, MEDLINE, and EMBASE were searched for articles that examined psychological interventions in contexts of ongoing threat of either IPV or organized violence and used trauma-related outcome measures. The search was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data on study population, ongoing threat setting and design, intervention components, evaluation methods, and outcomes were extracted, and study quality was assessed using the Mixed-Method Appraisal Tool. Eighteen papers featuring 15 trials were included (12 on organized violence and 3 on IPV). For organized violence, most studies showed moderate to large effects in reducing trauma-related symptoms when compared to waitlists. For IPV, findings were varied. Most studies made adaptations related to culture and ongoing threat and found that providing psychological interventions was feasible. The findings, albeit preliminary with mixed methodological quality, showed psychological treatments can be beneficial and should not be withheld in the context of ongoing organized violence and IPV. Clinical and research recommendations are discussed.

Feasibility, Acceptability, and Impact of a self-guided e-learning Memory and Brain Health Promotion Program for Healthy Older Adults

OBJECTIVES

To examine the feasibility (e.g., completion rate), acceptability (e.g., satisfaction), and participant-reported impact (e.g., memory concerns, behavior change, goal attainment) of a self-guided, e-learning adaptation of a validated, facilitator-guided, in-person memory intervention for older adults.

METHODS

Participants were 139 healthy older adults (mean age: 73 ± 7, 73% women). Participation tracking and pre/post questionnaires embedded within the e-learning program were used to assess feasibility, acceptability, and impact.

RESULTS

Sixty-eight percent of participants completed the program. Anonymous feedback data indicated a high level of satisfaction with the program, the pace and clarity of the learning modules, and the user interface. Suggested improvements included offering more interaction with others and addressing minor platform glitches. There was a 41% decrease in the prevalence of concern about memory changes from baseline to posttest. The majority of participants reported an increase in use of memory strategies and uptake of health-promoting lifestyle behaviors. All participants reported moderate-to-high satisfaction with personal goal attainment.

CONCLUSIONS

The program demonstrated good feasibility, acceptability, and lead to reduction in age-related memory concerns.

CLINICAL IMPLICATIONS

Self-guided, e-learning programming shows promise for fostering positive adaptation to age-related memory changes and improving the uptake of evidence-based strategies to promote brain health among older adults.

Exposure-based cognitive-behaviour therapy for anxiety-related disorders in pregnancy (ADEPT): Results of a feasibility randomised controlled trial of time-intensive versus weekly CBT

BACKGROUND

Exposure-based cognitive-behaviour therapies (CBT) are effective but their acceptability in pregnancy is untested. Time-intensive delivery of CBT (INT-CBT) may accelerate treatment response. This feasibility trial aimed to explore this.

METHODS

This multi-centre parallel-group trial recruited pregnant women with anxiety-related disorders via maternity and mental health settings and randomised (1:1) to INT-CBT (8-10 treatment hours over two weeks) or standard weekly one-hour CBT sessions (WCBT). Both groups also received late pregnancy and postpartum follow-ups. Participants received 10-12 total hours of individual therapy using remote delivery (95 %). Outcomes were assessed: at baseline; after two weeks of treatment, late pregnancy, at 1 and 3 months postpartum (by blinded assessors), alongside a qualitative interview. Pre-specified primary feasibility outcomes regarding acceptability, recruitment and retention were evaluated. The secondary outcome of adjusted mean difference was estimated for the proposed primary outcome.

RESULTS

All feasibility outcomes were met. Of 135 screened, 59 women were randomised into the trial (29 INT-CBT:30 WCBT). 93 % completed treatment and 81 % provided data at 3 m postpartum. No adverse effects were attributable to treatment. Women receiving INT-CBT showed a reduction in anxiety (GAD-7) after two weeks of treatment compared to WCBT (aMD = -4.17, 95%CI -6.03 to -2.31) with narrower difference at 3-month postpartum aMD = -0.11 (95%CI -3.23, 3.00). Women described the momentum of INT-CBT as helpful to drive change.

CONCLUSIONS

Exposure-based therapies are acceptable to pregnant women. INT-CBT may reduce anxiety quickly and should be tested in a confirmatory trial examining longer term outcomes. There may be limitations to generalisability from sampling and COVID.

Geri-Mobile Health: Feasibility of a VA Mental Health Mobile Apps Coaching Program for Older Veterans

OBJECTIVES

This program evaluation examined the feasibility, acceptability, and preliminary effects of an individualized coaching program to help older Veterans use VA mental health mobile apps to address mental health and well-being goals.

METHODS

The program delivers individual technical and clinical support to facilitate the use of mobile devices and VA apps. Participants completed assessments of mobile device proficiency, app use frequency, app comfort, quality of life, and mental health symptoms (completed by a subset, n = 11) pre- and post-participation.

RESULTS

Of 24 enrollees, 17 completed the program and received an average of 7.58 (SD = 2.87) sessions including the initial assessment. Mobile device proficiency (t (16) = -3.80, p = .002) and number of days/week apps were used (t (16) = -2.34, p = .032) increased significantly from pre- to post-participation. Depressive and anxiety scores decreased significantly (t (10) = 3.16, p = .010; t (10) = 3.29, p = .008) among the subset completing those measures. Overall satisfaction was high; 100% reported they would recommend the program.

CONCLUSIONS

Findings suggest the program is feasible, highly acceptable, and increases mobile device proficiency and use of apps.

CLINICAL IMPLICATIONS

Coaching programs can equip older adults with the skills to use mental health apps.

Measuring grip strength in adolescents and adults with cerebral palsy in a clinic setting: Feasibility, reliability, and clinical associations

AIM

To determine the feasibility and reliability of measuring grip strength and its association with anthropometrics and diseases among adolescents and adults (≥16 years old) with cerebral palsy (CP).

METHOD

In this cross-sectional study, individuals with CP, classified in Gross Motor Function Classification System (GMFCS)/Manual Ability Classification System (MACS) levels I to V, were recruited to measure grip strength, anthropometrics, and self-reported current/history of disease during a routine clinical visit. Feasibility was determined as the proportion recruited/consented/completed testing. Test-retest reliability of three maximal effort trials per side was assessed. Linear regression determined associations of grip strength with anthropometrics after adjusting for age, sex, and GMFCS. The predictive ability of GMFCS alone, grip strength alone, GMFCS + grip strength, and GMFCS × grip strength for diseases was compared.

RESULTS

Of 114 individuals approached, 112 participated and 111 successfully completed all tasks. There was good to excellent reliability of test-retest grip strength between trials for dominant and non-dominant sides for the entire cohort and when stratified by each GMFCS and MACS level (intraclass correlation coefficient range 0.83-0.97). Sex, GMFCS, MACS, body mass, and waist circumference were associated with grip strength (p < 0.05), but not hip circumference, waist:hip ratio, or triceps skinfold thickness. Modeling grip strength with GMFCS had a higher predictive value for relevant diseases than GMFCS alone.

INTERPRETATION

Grip strength is a feasible and reliable measurement for CP, and is associated with some demographics and anthropometric measures. Grip strength, in addition to the GMFCS, enhanced prediction of disease outcomes.

WHAT THIS PAPER ADDS

Measurement of hand grip strength is clinically feasible for adolescents/adults with cerebral palsy. Grip strength has good to excellent test-retest reliability across Gross Motor Function Classification System (GMFCS) and Manual Ability Classification System (MACS) levels. Grip strength is associated with sex, weight, waist circumference, GMFCS, and especially MACS. Grip strength, in addition to GMFCS, shows promise for enhancing disease prediction in this cohort.

The Feasibility and Effects of Smartphone-Based Application on Cardiac Rehabilitation for Patients After Percutaneous Coronary Intervention: A Randomized Controlled Trial

BACKGROUND

Cardiac rehabilitation (CR) referral and participation are generally found to be underused worldwide. The data in Asian regions suggest significant underutilization compared with western countries.

OBJECTIVES

To promote the continuity and effects of CR, this study aimed at supporting self-care and improving CR effects in phase II CR with mobile health application for Macao patients who have undergone percutaneous coronary intervention.

METHODS

The study was a randomized controlled trial conducted between January 2018 and June 2020 in a nongovernmental Hospital. Social cognitive theory was applied in the intervention for an experimental group. Measurements including anxiety and depression level, medication adherence, exercise capacity, physical activity level, cardiovascular risk modification, self-efficacy, quality of life, use of healthcare resources, mHealth CR utility, and satisfaction were analyzed.

RESULTS

One hundred forty eligible patients were recruited, and 110 patients completed the study. Significant interventional effects of the experimental group were found on the reduction of total cholesterol, low-density lipoprotein, sitting time, anxiety level, and total anxiety and depression level ( P < .05). In addition, significant improvement on the 6-minute walk test, regular exercise performance, self-efficacy of cardiac exercise and diet, and quality of life were found as interventional effects in the experimental group ( P < .05). The feasibility of intervention was achieved in a satisfactory level.

CONCLUSIONS

This theoretically grounded mobile health CR study was a unique program tailor-made to meet the care needs of patients post percutaneous coronary intervention. It was feasible and effective to support CR effects and adherence and would inform further design of clinical practice and public policies.

Feasibility of a 3-Minute Mindful Breathing Intervention for Enhancing Psychiatric Mental Health Nurses' Resilience During COVID: Findings From a 4-Week Pilot Study

COVID created a perfect storm of conditions leading to excessive and prolonged stress on already vulnerable nurses. This study examines the feasibility of enhancing psychiatric mental health nurses' (PMHNs') resilience by practicing a 3-minute mindfulness-based intervention. In this pilot study, we explored if PMHNs could be recruited and retained for intervention implementation, intervention acceptability, and measurement of any notable changes over the prescribed period. Study feasibility is reflected in high participant retention and increased postintervention resilience scores. Given the positive outcomes, a larger-scale study is warranted. Additional areas of opportunity include strategies for increasing participant uptake, and, due to limited acceptability feedback, the introduction of a usefulness scale.

A multi-institutional feasibility study of intra-arterial chemotherapy in children with retinoblastoma. A Children's Oncology Group study (COG ARET12P1)

BACKGROUND

Intra-arterial chemotherapy (IA) as a treatment to salvage the eye with advanced retinoblastoma is increasingly utilized based on successes reported by institutions around the world mainly through retrospective studies.

OBJECTIVE

To study the feasibility of delivering melphalan directly into the ophthalmic artery in a multi-institutional prospective study in children with newly diagnosed unilateral group D retinoblastoma.

METHODS

The Children's Oncology Group (COG) initiated study ARET12P1 in 2014 and was open to nine institutions. Eligible patients older than six months of age were enrolled. The feasibility of delivering three injections of melphalan into the ophthalmic artery every 28 days was assessed.

RESULTS

Nine institutions participated in this trial. Fourteen patients were enrolled, two of whom were unevaluable for feasibility. Four patients experienced a feasibility failure. In two patients, the ophthalmic artery could not be accessed for the second IA injection, in one the artery could not be accessed for the first injection, and one patient experienced grade 4 hypotension during the procedure.

CONCLUSION

Delivery of prescribed therapy within the context of this study did not meet the feasibility goals of the study with only a 67% feasibility success rate. These results should caution centers that plan to initiate this treatment and suggest investment in training to achieve technical expertise or referral to centers with expertise.

Feasibility of a Telehealth Compensatory Cognitive Training Program for Older Adults with Mild Cognitive Impairment

OBJECTIVES

Older adults experiencing mild cognitive impairment (MCI) may benefit from compensatory cognitive training (CCT). This study investigated the feasibility of telehealth CCT among older adults with MCI.

METHODS

Adults age 55+ with MCI (n = 28) and a care partner (n = 18) participated in telehealth CCT. Participants rated sessions' technological interference on an adapted 0-100 session rating scale (higher scores=less interference). Clinicians provided ratings and qualitative feedback on types of interference experienced. Feasibility was assessed by enrollment and completion rates, and through ratings and feedback.

RESULTS

6% of contacts declined participation due to telehealth delivery. 24 of 28 participants completed the program, with no dropouts due to telehealth. Participants (M = 81.32, SD = 25.61) and clinicians (M = 76.24, SD = 33.37) rated technological interference as infrequent. Clinicians indicated most interference did not impact sessions, though 4% required rescheduling due to interference.

CONCLUSIONS

Telehealth delivery was not a barrier to recruitment, enrollment, or completion of CCT. Technological problems were mostly minor. Telehealth CCT could support access to and intervention among older adults with MCI.

CLINICAL IMPLICATIONS

Telehealth CCT for older adults with MCI was feasible, with mild issues not impacting session completion. Clinicians should be prepared to offer support as technological issues arise, or have dedicated technological support services.

Feasibility of Gastrografin Use for Adhesive Small Bowel Obstruction in Low-Income Countries

INTRODUCTION

Small bowel obstruction (SBO) is one of the most common causes for hospital admission in Ethiopia. The use of water-soluble contrast agents (WSCAs) such as Gastrografin to manage adhesive SBO can predict nonoperative resolution of SBO and reduce decision time to surgery and length of hospital stay. However, nothing is known about practice patterns and Gastrografin use in low-income settings. We sought to characterize current management practices, including use of WSCAs, as well as outcomes for patients with SBO in Addis Ababa, Ethiopia.

METHODS

We conducted a mixed-methods study consisting of a survey of surgeons throughout Ethiopia and a retrospective record review at five public, tertiary care-level teaching hospitals in Addis Ababa.

RESULTS

Of the 76 surgeons who completed the survey, 63% had heard of the use of WSCAs for SBO and only 11% used oral agents for its management. Chart review of 149 patients admitted with SBO showed the most common etiology was adhesion (39.6% of admissions), followed by small bowel volvulus (20.8%). Most patients (83.2%) underwent surgery during their admission. The most common diagnosis in patients who did not require surgery was also adhesion (68.0%), as well as for those who had surgery (33.9%), followed by small bowel volvulus (24.2%).

CONCLUSIONS

The etiology of SBO in Ethiopia may be changing, with postoperative adhesions becoming more common than other historically more prevalent causes. Although a Gastrografin protocol as a diagnostic and potentially therapeutic aid for SBO is feasible in this population and setting, challenges can be anticipated, and future studies of protocol implementation and effectiveness are needed to further inform its utility in Ethiopia and other low-income and middle-income countries.

Evaluation of the feasibility of using inorganic and organic acids for the extraction of amino acids from high-protein material (mealworm larvae) by chemical hydrolysis

High-protein mealworm larvae (Tenebrio molitor) were treated with organic and inorganic acids in order to check the feasibility of applying acid hydrolyzates derived from them. Hydrolysis was optimized for the highest content of amino acids that have beneficial effects on plant development. The response surface method served the purpose of selecting optimal process conditions for such media as phosphoric acid, citric acid, acetic acid and mixtures of phosphoric and citric acids. The elemental composition of the best formulations and their amino acid profile was determined. Plant tests on cucumber (germination and pot tests) revealed the beneficial effect of the hydrolyzates on plant biometric parameters. By offering valuable insights into the relationship between fertilizer treatments and plant growth, our study contributes to developing sustainable agricultural practices and improved crop productivity.
