A pragmatic randomized controlled exploratory trial of the effectiveness of Eye Movement Desensitization and Reprocessing therapy for psychotic disorder.

BACKGROUND: People with severe mental illness are often excluded from trials related to Eye Movement Desensitization and Reprocessing (EMDR) therapy. Principal concerns are that they may not tolerate treatment, might risk relapse or that psychotic symptoms may worsen. There is however building evidence of a traumatogenic etiology of psychotic disorder that may benefit therapeutically from EMDR. However, EMDR in this role is done mainly in specialist tertiary settings. AIM: To conduct a randomized exploratory trial of prospective treatment of EMDR for people with psychotic disorder and a history of trauma in an adult community mental health service. METHODS: A randomized exploratory trial with a controlled pilot design was employed to conduct a prospective treatment and six-month follow-up study with an interim 10-week analysis in a rural county in the UK (population 538,000). We recruited participants with psychotic disorder who had a reported history of trauma and were interested in receiving trauma therapy. They were then randomized to either receive EMDR or treatment as usual (TAU). The primary instrument used was the Impact of Events Scale (IES) with secondary instruments of Positive and Negative Symptoms of Psychotic Disorder (PANSS), PTSD Checklist (PCL-C), and subjective Quality of Life (MANSA). RESULTS: IES scores showed significant improvements in the EMDR group (n = 24, age 42.0 SD (14.5), 42% male) compared to the TAU group (n = 12, age 34.4 SD (11.3), 50% male) at 10 weeks and at six months (p < 0.05). There were significant improvements in PCL-C and PANSS negative symptoms scores associated with treatment (p < 0.05). All other scales showed positive trends. CONCLUSIONS: This study demonstrates that EMDR can reduce the impact of traumatic events for patients with a psychotic disorder in a clinical setting in the UK. The improvements in psychotic disorder persisted for six months after treatment. TRIAL REGISTRATION: ISRCTN43816889.

Getting a balance between generalisation and specialisation in mental health services: a defence of general services.

Mental health services in the UK National Health Service have evolved to include primary-care generalist, secondary-care generalist and secondary-care specialist services. We argue that there continues to be an important role for the secondary-care generalists as they minimise interfaces, can live with diagnostic uncertainty and support continuity of care. The lack of commissioning and clinical boundaries in secondary-care generalist services can undermine their feasibility, leading to difficulties recruiting and retaining staff. There is a risk of a polo-mint service, where the specialist services on the edge are well resourced, but the secondary-care generalist services taking the greatest burden struggle to recruit and retain clinicians. We need to establish equity in resources and expectations between generalist and specialist mental health services.Declaration of interestNone.

Dynamical coarse-graining of highly fluctuating membranes under shear flow.

The effect of strong shear flow on highly fluctuating lamellar systems stabilized by intermembrane collisions via the Helfrich interaction is studied. Advection enters the microscopic equation of motion for a single membrane via a nonlinear coupling. Upon coarse-graining the theory for a single bilayer up to the length scale of the collision length, at which a hydrodynamic description applies, an additional dynamical coupling is generated which is of the form of a wave-vector-dependent tension that is nonlinear in the applied shear rate. This new term has consequences for the effects of strong flow on the stability and dynamics of lamellar surfactant phases.
