ABSTRACT

Background: Guided self-help has been shown to be effective for other mental conditions and, if effective for post-traumatic stress disorder, would offer a time-efficient and accessible treatment option, with the potential to reduce waiting times and costs. Objective: To determine if trauma-focused guided self-help is non-inferior to individual, face-to-face cognitive-behavioural therapy with a trauma focus for mild to moderate post-traumatic stress disorder to a single traumatic event. Design: Multicentre pragmatic randomised controlled non-inferiority trial with economic evaluation to determine cost-effectiveness and nested process evaluation to assess fidelity and adherence, dose and factors that influence outcome (including context, acceptability, facilitators and barriers, measured qualitatively). Participants were randomised in a 1 : 1 ratio. The primary analysis was intention to treat using multilevel analysis of covariance. Setting: Primary and secondary mental health settings across the United Kingdom's National Health Service. Participants: One hundred and ninety-six adults with a primary diagnosis of mild to moderate post-traumatic stress disorder were randomised with 82% retention at 16 weeks and 71% at 52 weeks. Nineteen participants and ten therapists were interviewed for the process evaluation. Interventions: Up to 12 face-to-face, manualised, individual cognitive-behavioural therapy with a trauma focus sessions, each lasting 60-90 minutes, or to guided self-help using Spring, an eight-step online guided self-help programme based on cognitive-behavioural therapy with a trauma focus, with up to five face-to-face meetings of up to 3 hours in total and four brief telephone calls or e-mail contacts between sessions. Main outcome measures: Primary outcome: the Clinician-Administered PTSD Scale for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, at 16 weeks post-randomisation. Secondary outcomes: included severity of post-traumatic stress disorder symptoms at 52 weeks, and functioning, symptoms of depression, symptoms of anxiety, alcohol use and perceived social support at both 16 and 52 weeks post-randomisation. Those assessing outcomes were blinded to group assignment. Results: Non-inferiority was demonstrated at the primary end point of 16 weeks on the Clinician-Administered PTSD Scale for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition [mean difference 1.01 (one-sided 95% CI -∞ to 3.90, non-inferiority p = 0.012)]. Clinician-Administered PTSD Scale for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, score improvements of over 60% in both groups were maintained at 52 weeks but the non-inferiority results were inconclusive in favour of cognitive-behavioural therapy with a trauma focus at this timepoint [mean difference 3.20 (one-sided 95% confidence interval -∞ to 6.00, non-inferiority p = 0.15)]. Guided self-help using Spring was not shown to be more cost-effective than face-to-face cognitive-behavioural therapy with a trauma focus although there was no significant difference in accruing quality-adjusted life-years, incremental quality-adjusted life-years -0.04 (95% confidence interval -0.10 to 0.01) and guided self-help using Spring was significantly cheaper to deliver [£277 (95% confidence interval £253 to £301) vs. £729 (95% CI £671 to £788)]. Guided self-help using Spring appeared to be acceptable and well tolerated by participants. No important adverse events or side effects were identified. Limitations: The results are not generalisable to people with post-traumatic stress disorder to more than one traumatic event. Conclusions: Guided self-help using Spring for mild to moderate post-traumatic stress disorder to a single traumatic event appears to be non-inferior to individual face-to-face cognitive-behavioural therapy with a trauma focus and the results suggest it should be considered a first-line treatment for people with this condition. Future work: Work is now needed to determine how best to effectively disseminate and implement guided self-help using Spring at scale. Trial registration: This trial is registered as ISRCTN13697710. Funding: This award was funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme (NIHR award ref: 14/192/97) and is published in full in Health Technology Assessment; Vol. 27, No. 26.

Post-traumatic stress disorder is a common, disabling condition that can occur following major traumatic events. Typical symptoms include distressing reliving, avoidance of reminders and feeling a current sense of threat. First-choice treatments for post-traumatic stress disorder are individual, face-to-face talking treatments, of 12­16 hours duration, including cognitive behavioural therapy with a trauma focus. If equally effective treatments could be developed that take less time and can be largely undertaken in a flexible manner at home, this would improve accessibility, reduce waiting times and hence the burden of disease. RAPID was a randomised controlled trial using a web-based programme called Spring. The aim was to determine if trauma-focused guided self-help provided a faster and cheaper treatment for post-traumatic stress disorder than first-choice face-to-face therapy, while being equally effective. Guided self-help using Spring is delivered through eight steps. A therapist provides a 1-hour introductory meeting followed by four further, fortnightly sessions of 30 minutes each and four brief (around 5 minutes) telephone calls or e-mail contacts between sessions. At each session, the therapist reviews progress and guides the client through the programme, offering continued support, monitoring, motivation and problem-solving. One hundred and ninety-six people with post-traumatic stress disorder to a single traumatic event took part in the study. Guided self-help using Spring was found to be equally effective to first-choice face-to-face therapy at reducing post-traumatic stress disorder symptoms at 16 weeks. Very noticeable improvements were maintained at 52 weeks post-randomisation in both groups, when most results were inconclusive but in favour of face-to-face therapy. Guided self-help using Spring was significantly cheaper to deliver and appeared to be well-tolerated. It is noteworthy that not everyone benefitted from guided self-help using Spring, highlighting the importance of considering it on a person-by-person basis, and personalising interventions. But, the RAPID trial has demonstrated that guided self-help using Spring provides a low-intensity treatment option for people with post-traumatic stress disorder that is ready to be implemented in the National Health Service.

ABSTRACT

OBJECTIVE: To determine if guided internet based cognitive behavioural therapy with a trauma focus (CBT-TF) is non-inferior to individual face-to-face CBT-TF for mild to moderate post-traumatic stress disorder (PTSD) to one traumatic event. DESIGN: Pragmatic, multicentre, randomised controlled non-inferiority trial (RAPID). SETTING: Primary and secondary mental health settings across the UK's NHS. PARTICIPANTS: 196 adults with a primary diagnosis of mild to moderate PTSD were randomised in a 1:1 ratio to one of two interventions, with 82% retention at 16 weeks and 71% retention at 52 weeks. 19 participants and 10 therapists were purposively sampled and interviewed for evaluation of the process. INTERVENTIONS: Up to 12 face-to-face, manual based, individual CBT-TF sessions, each lasting 60-90 minutes; or guided internet based CBT-TF with an eight step online programme, with up to three hours of contact with a therapist and four brief telephone calls or email contacts between sessions. MAIN OUTCOME MEASURES: Primary outcome was the Clinician Administered PTSD Scale for DSM-5 (CAPS-5) at 16 weeks after randomisation (diagnosis of PTSD based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders, fifth edition, DSM-5). Secondary outcomes included severity of PTSD symptoms at 52 weeks, and functioning, symptoms of depression and anxiety, use of alcohol, and perceived social support at 16 and 52 weeks after randomisation. RESULTS: Non-inferiority was found at the primary endpoint of 16 weeks on the CAPS-5 (mean difference 1.01, one sided 95% confidence interval -∞ to 3.90, non-inferiority P=0.012). Improvements in CAPS-5 score of more than 60% in the two groups were maintained at 52 weeks, but the non-inferiority results were inconclusive in favour of face-to-face CBT-TF at this time point (3.20, -∞ to 6.00, P=0.15). Guided internet based CBT-TF was significantly (P<0.001) cheaper than face-to-face CBT-TF and seemed to be acceptable and well tolerated by participants. The main themes of the qualitative analysis were facilitators and barriers to engagement with guided internet based CBT-TF, treatment outcomes, and considerations for its future implementation. CONCLUSIONS: Guided internet based CBT-TF for mild to moderate PTSD to one traumatic event was non-inferior to individual face-to-face CBT-TF and should be considered a first line treatment for people with this condition. TRIAL REGISTRATION: ISRCTN13697710.

ABSTRACT

PRC2 is a multisubunit methyltransferase involved in epigenetic regulation of early embryonic development and cell growth. The catalytic subunit EZH2 methylates primarily lysine 27 of histone H3, leading to chromatin compaction and repression of tumor suppressor genes. Inhibiting this activity by small molecules targeting EZH2 was shown to result in antitumor efficacy. Here, we describe the optimization of a chemical series representing a new class of PRC2 inhibitors which acts allosterically via the trimethyllysine pocket of the noncatalytic EED subunit. Deconstruction of a larger and complex screening hit to a simple fragment-sized molecule followed by structure-guided regrowth and careful property modulation were employed to yield compounds which achieve submicromolar inhibition in functional assays and cellular activity. The resulting molecules can serve as a simplified entry point for lead optimization and can be utilized to study this new mechanism of PRC2 inhibition and the associated biology in detail.

ABSTRACT

Abrogation of errant signaling along the MAPK pathway through the inhibition of B-RAF kinase is a validated approach for the treatment of pathway-dependent cancers. We report the development of imidazo-benzimidazoles as potent B-RAF inhibitors. Robust in vivo efficacy coupled with correlating pharmacokinetic/pharmacodynamic (PKPD) and PD-efficacy relationships led to the identification of RAF265, 1, which has advanced into clinical trials.

ABSTRACT

Utilizing structure-based drug design, a novel dihydropyridopyrimidinone series which exhibited potent Hsp90 inhibition, good pharmacokinetics upon oral administration, and an excellent pharmacokinetic/pharmacodynamic relationship in vivo was developed from a commercial hit. The exploration of this series led to the selection of NVP-HSP990 as a development candidate.

ABSTRACT

Medicinal leeches are commonly used after finger replantation to treat surgically unsalvageable venous congestion. Infection from Aeromonas hydrophila is a recognized complication of leech therapy that can be underestimated by the medical community. Ciprofloxacin and trimethoprim-sulfamethoxazole are the most commonly recommended prophylactic antibiotics used to prevent A. hydrophila infections during leech therapy. Here, we report 2 cases of ciprofloxacin-resistant Aeromonas infections, occurring within 4 months of each other. Both cases developed after leech therapy for unsuccessful digital replantation. These infections were successfully treated with ceftriaxone. Ciprofloxacin-resistant Aeromonas should be recognized when determining prophylactic antibiotic protocols for replant centers when leech therapy is used for finger replantation.

ABSTRACT

A ligand-based 3D pharmacophore model for serine/threonine kinase CDC7 inhibition was created and successfully applied in the discovery of novel 2-(heteroaryl)-6,7-dihydrothieno[3,2-c]pyridin-4(5H)-ones. The pharmacophore model provided a hypothesis for lead generation missed by docking to a homology model. Medicinal chemistry exploration of the series revealed clear structure-activity relationships consistent with the pharmacophore model and pointed to further optimization opportunities.

ABSTRACT

Data from the Equal Employment Opportunity Commission (EEOC) Integrated Mission System database were analyzed with specific reference to allegations of workplace discrimination filed by individuals with cancer under ADA Title One. These 6,832 allegations, filed between July 27, 1992 and September 30, 2003, were compared to 167,798 allegations from a general disability population on the following dimensions: type of workplace discrimination; demographic characteristics of the charging parties (CPs); the industry designation, location, and size of employers; and the outcome or resolution of EEOC investigations. Results showed allegations derived from CPs with cancer were more likely than those in the general disability population to include issues involving discharge, terms and conditions of employment, lay-off, wages, and demotion. Compared to the general disability group, CPs with cancer were more likely to be female, older, and White. Allegations derived from CPs with cancer were also more likely to be filed against smaller employers (15-100 workers) or those in service industries. Finally, the resolution of allegations by CPs with cancer were more likely to be meritorious than those filed from the general disability population; that is, actual discrimination is more likely to have occurred.

ABSTRACT

BACKGROUND: The concept of self-efficacy has been proposed as a suitable outcome measure in psychiatry. Self-efficacy refers to an individual's belief that he or she can control important aspects of his or her life. An audit of 67 consecutive clients attending an acute psychiatric day unit was conducted, measuring self-efficacy at admission to the unit and at discharge. CONCLUSION: The concept of self-efficacy was easily explained to clients, and was measured using a 15-point questionnaire. Self-efficacy increased following treatment in the day unit, and this increase appears to reflect an underlying change in the individual's self-belief.
