A Retrospective Pilot Study of Imagery Rehearsal Therapy Enhanced with Narrative Therapy Principles for the Treatment of Nightmares in US Military Veterans.

Introduction Chronic nightmares are a common and disabling feature of posttraumatic stress disorder (PTSD) for which broadly effective treatments are still lacking. While imagery rehearsal therapy (IRT) demonstrates benefits for patients with idiopathic nightmares and some patients with PTSD-related nightmares, research indicates it may be less beneficial for veterans. Narrative therapy (NT) is a form of psychotherapy which is client-centered and value-focused and has demonstrated benefits for PTSD patients. The application of NT principles to IRT may provide a valuable therapeutic approach for treatment in veterans. Objective To perform a retrospective chart review of veteran clients participating in a novel, brief intervention developed by the first author consisting of IRT enhanced with NT principles (N-IRT) for the treatment of nightmares. The primary outcomes were nightmare frequency and intensity, and the secondary outcome was the impact of the intervention on nightmare distress and coping, subjective sleep quality, and overall PTSD symptoms. Materials and Methods We conducted retrospective chart reviews for eight veterans referred to the first author for the treatment of nightmares, who completed N-IRT, including baseline and end-of-treatment measures. The protocol involved a single 60-minute NT-enhanced rescripting session and assigned homework to rehearse the revised dream script, and a follow-up evaluation 4 weeks later. The subjects completed a sleep and nightmare interview developed by the first author and the PTSD Checklist at baseline and after the intervention at the follow-up evaluation. Paired t -tests were conducted to test for pre-to-post differences. Results In the statistical analysis, we observed a statistically significant and clinically meaningful reduction in the frequency ( p = 0.04) and intensity of nightmares ( p = 0.001) from pretreatment to the 1-month follow-up. Measures of nightmare-associated emotional distress, the ability to cope with nightmares, sleep duration and sleep efficiency, as well as overall PTSD symptoms also demonstrated significant improvements. Conclusion These pilot data provide compelling preliminary evidence that a single-session IRT intervention modified with NT (N-IRT) is effective in reducing nightmare frequency and intensity, reducing nightmare distress, improving the act of coping with nightmares, and improving sleep quality and overall PTSD symptoms in veterans. Further investigation of this method with gold-standard clinical trial designs and larger sample sizes is indicated to confirm effectiveness and to better understand the possible mechanisms of treatment effect.

Vascular access in children requiring maintenance haemodialysis: a consensus document by the European Society for Paediatric Nephrology Dialysis Working Group

There are three principle forms of vascular access available for the treatment of children with end stage kidney disease (ESKD) by haemodialysis: tunnelled catheters placed in a central vein (central venous lines, CVLs), arteriovenous fistulas (AVF), and arteriovenous grafts (AVG) using prosthetic orbiological material. Compared with the adult literature, there are few studies in children to provide evidence based guidelines for optimal vascular access type or its management and outcomes in children with ESKD.

Vascular access in children requiring maintenance haemodialysis: a consensus document by the European Society for Paediatric Nephrology Dialysis Working Group.

BACKGROUND: There are three principle forms of vascular access available for the treatment of children with end stage kidney disease (ESKD) by haemodialysis: tunnelled catheters placed in a central vein (central venous lines, CVLs), arteriovenous fistulas (AVF), and arteriovenous grafts (AVG) using prosthetic or biological material. Compared with the adult literature, there are few studies in children to provide evidence based guidelines for optimal vascular access type or its management and outcomes in children with ESKD. METHODS: The European Society for Paediatric Nephrology Dialysis Working Group (ESPN Dialysis WG) have developed recommendations for the choice of access type, pre-operative evaluation, monitoring, and prevention and management of complications of different access types in children with ESKD. RESULTS: For adults with ESKD on haemodialysis, the principle of "Fistula First" has been key to changing the attitude to vascular access for haemodialysis. However, data from multiple observational studies and the International Paediatric Haemodialysis Network registry suggest that CVLs are associated with a significantly higher rate of infections and access dysfunction, and need for access replacement. Despite this, AVFs are used in only ∼25% of children on haemodialysis. It is important to provide the right access for the right patient at the right time in their life-course of renal replacement therapy, with an emphasis on venous preservation at all times. While AVFs may not be suitable in the very young or those with an anticipated short dialysis course before transplantation, many paediatric studies have shown that AVFs are superior to CVLs. CONCLUSIONS: Here we present clinical practice recommendations for AVFs and CVLs in children with ESKD. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system has been used to develop and GRADE the recommendations. In the absence of high quality evidence, the opinion of experts from the ESPN Dialysis WG is provided, but is clearly GRADE-ed as such and must be carefully considered by the treating physician, and adapted to local expertise and individual patient needs as appropriate.
