Introduction: The benefits of theatre and arts-based initiatives for enhancing the health and wellbeing of adults, regardless of mental health status, are well-documented. Theatre methodologies offer a platform for co-produced experiential learning, promoting perspective-taking and effective communication among staff and service users. This project aimed to bring together service users and mental health professionals through workshops conducted by an experiential theatre company, focusing on themes such as relationship dynamics, co-production, empowerment and perspective-taking. Notably, the sessions were conducted online due to the COVID-19 pandemic., Methods: The study sought to explore the experiences, learning outcomes and work-related wellbeing benefits of participating in this innovative project. Methods involved inviting East London Foundation Trust members to eight weekly online workshops, culminating in a co-created filmed performance. Interviews conducted 9 months to a year later with participants and facilitators were thematically analysed., Results: Results revealed four key themes: (1) personal and collective growth through storytelling and embodied acting experiences; (2) the importance of workshop structure for experiential learning; (3) challenging traditional role definitions through diminished hierarchy; and (4) sustained impacts on time management at work and in personal lives., Conclusions: In conclusion, participants valued their involvement, indicating that theatre-based co-produced learning enhances communication and interpersonal skills in mental healthcare settings. These findings suggest the potential for integrating such approaches into healthcare education and training programs., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship and/or publication of this article., (© The Author(s) 2024.)

Emerging consensus among enactivist philosophers and embodied mind theorists suggests that seeking to understand mental illness we need to look out of our skulls at the ecology of the brain. Still, the complex links between materiality (in broadest sense of material objects, habits, practices and environments) and mental health remain little understood. This paper discusses the benefits of adopting a material engagement approach to embodied and enactive psychiatry. We propose that the material engagement approach can change the geography of the debate over the nature of mental disorders and through that help to develop theoretical and practical insights that could improve management and treatment for various psychiatric conditions. We investigate the potential role of Material Engagement Theory (MET) in psychiatry using examples of aetiologically different mental illnesses (schizophrenia and dementia) in respect of their shared phenomenological manifestations, focusing particularly on issues of memory, self-awareness, embodiment and temporality. The effective study of socio-material relations allows better understanding of the semiotic significance and agency of specific materials, environments and technical mediations. There is unrealised potential here for creating new approaches to treatment that can broaden, challenge or complement existing interventions and practices of care., (© 2024. The Author(s).)

Background: Functional somatic symptoms (FFS) and bodily distress disorders are highly prevalent across all medical settings. Services for these patients are dispersed across the health care system with minimal conceptual and operational integration, and patients do not currently access therapeutic offers in significant numbers due to a mismatch between their and professionals' understanding of the nature of the symptoms. New service models are urgently needed to address patients' needs and to align with advances in aetiological evidence and diagnostic classification systems to overcome the body-mind dichotomy., Method: A panel of clinical experts from different clinical services involved in providing aspects of health care for patients with functional symptoms reviewed the current care provision. This review and the results from a focus group exploration of patients with lived experience of functional symptoms were explored by the multidisciplinary expert group, and the conclusions are summarised as recommendations for best practice., Results: The mapping exercise and multidisciplinary expert consultation revealed five themes for service improvement and pathway development: time/access, communication, barrier-free care, choice and governance. Service users identified four meta-themes for best practice recommendations: focus on healthcare professional communication and listening skills as well as professional attributes and knowledge base to help patients being both believed and understood in order to accept their condition; systemic and care pathway issues such as stronger emphasis on primary care as the first point of contact for patients, resources to reduce the length of the patient journey from initial assessment to diagnosis and treatment., Conclusion: We propose a novel, integrated care pathway for patients with 'functional somatic disorder', which delivers care according to and working with patients' explanatory beliefs. The therapeutic model should operate based upon an understanding of the embodied nature of patient's complaints and provide flexible access points to the care pathway., (© 2024. The Author(s).)

A set of dipolar molecular rotor compounds was designed, synthesized and adsorbed as self-assembled 2D arrays on Ag(111) surfaces. The title molecules are constructed from three building blocks: (a) 4,8,12-trioxatriangulene (TOTA) platforms that are known to physisorb on metal surfaces such as Au(111) and Ag(111), (b) phenyl groups attached to the central carbon atom that function as pivot joints to reduce the barrier to rotation, (c) pyridine and pyridazine units as small dipolar units on top. Theoretical calculations and scanning tunneling microscopy (STM) investigations hint at the fact that the dipoles of neighboring rotors interact through space through pairs of energetically favorable head-to-tail arrangements., (© 2021 The Authors.

Background: Severe mental illness (SMI) is associated with care delivery problems because of the high levels of clinical resources needed to address patient's psychosocial impairment and to support inclusion in society. Current routine appointment systems do not adequately foster recovery care and are not systematically capturing information suggestive of urgent care needs. This study aimed to assess the feasibility, acceptability, and potential clinical benefits of a mobile technology health management tool to enhance community care for people with severe mental illness., Methods: This randomised-controlled feasibility pilot study utilised mixed quantitative (measure on subjective quality of life as primary outcome; questionnaires on self-management skills, medication adherence scale as secondary outcomes) and qualitative (thematic analysis) methodologies. The intervention was a simple interactive technology (Short Message Service - SMS) communication system called 'Florence', and had three components: medication and appointment reminders, daily individually defined wellbeing scores and optionally coded request for additional support. Eligible participants (diagnosed with schizophrenia, schizoaffective disorder or bipolar disorder ≥1 year) were randomised (1:1) to either treatment as usual (TAU, N = 29) or TAU and the technology-assisted intervention (N = 36)., Results: Preliminary results suggest that the health technology tool appeared to offer a practicable and acceptable intervention for patients with SMI in managing their condition. Recruitment and retention data indicated feasibility, the qualitative analysis identified suggestions for further improvement of the intervention. Patients engaged well and benefited from SMS reminders and from monitoring their individual wellbeing scores; recommendations were made to further personalise the intervention. The care coordinators did not utilise aspects of the intervention per protocol due to a variety of organisational barriers. Quantitative analysis of outcomes (including a patient-reported outcome measure on subjective quality of life, self-efficacy/competence and medication adherence measures) did not identify significant changes between groups over time in favour of the Florence intervention, given high baseline scores. The wellbeing scores, however, were positively correlated with all outcome measures., Conclusion: It is feasible to conduct an adequately powered full trial to evaluate this intervention. Inclusion criteria should be revised to include patients with a higher level of need and clinicians should receive more in-depth assistance in managing the tools effectively. The preliminary data suggests that this intervention can aid recovery care and individually defined wellbeing scores are highly predictive of a range of recovery outcomes; they could, therefore, guide the allocation of routine care resources., Trial Registration: ISRCTN34124141 ; retrospectively registered, date of registration 05/11/2019., (© 2021.

We present the synthesis and the spin switching efficiencies of Ni(II)-porphyrins substituted with azopyridines as covalently attached photoswitchable ligands. The molecules are designed in such a way that the azopyridines coordinate to the Ni ion if the azo unit is in cis configuration. For steric reasons no intramolecular coordination is possible if the azopyridine unit adopts the trans configuration. Photoisomerization of the azo unit between cis and trans is achieved upon irradiation with 505 nm ( trans → cis ) and 435 nm ( cis → trans ). Concurrently with the isomerization and coordination/decoordination, the spin state of the Ni ion switches between singlet (low-spin) and triplet (high-spin). Previous studies have shown that the spin switching efficiency is strongly dependent on the solvent and on the substituent at the 4-position of the pyridine unit. We now introduced thiol, disulfide, thioethers, nitrile and carboxylic acid groups and investigated their spin switching efficiency., (Copyright © 2020, Ludwig et al.; licensee Beilstein-Institut.)

Photochromic systems have been used to achieve a number of engineering functions such as light energy conversion, molecular motors, pumps, actuators, and sensors. Key to practical applications is a high efficiency in the conversion of light to chemical energy, a rigid structure for the transmission of force to the environment, and directed motion during isomerization. We present a novel type of photochromic system (diindane diazocines) that converts visible light with an efficiency of 18 % to chemical energy. Quantum yields are exceptionally high with >70 % for the cis-trans isomerization and 90 % for the back-reaction and thus higher than the biochemical system rhodopsin (64 %). Two diastereomers (meso and racemate) were obtained in only two steps in high yields. Both isomers are directional switches with high conversion rates (76-99 %). No fatigue was observed after several thousands of switching cycles in both systems., (© 2020 The Authors. Published by Wiley-VCH Verlag GmbH & Co. KGaA.)

Objectives: To evaluate the feasibility of a randomised trial of a modified, pre-existing, mindfulness meditation smartphone app for women with chronic pelvic pain., Design: Three arm randomised feasibility trial., Setting: Women were recruited at two gynaecology clinics in the UK. Interventions were delivered via smartphone or computer at a location of participants choosing., Participants: Women were eligible for the study if they were over 18, had been experiencing organic or non-organic chronic pelvic pain for 6 months or more, and had access to a computer or smartphone. 90 women were randomised., Interventions: Daily mindfulness meditation delivered by smartphone app, an active control app which delivered muscle relaxation techniques, and usual care without app. Interventions were delivered over 60 days., Primary and Secondary Outcome Measures: Outcomes included length of recruitment, follow-up rates, adherence to the app interventions, and clinical outcomes measured at baseline, two, three and 6 months., Results: The target sample size was recruited in 145 days. Adherence to the app interventions was extremely low (mean app use 1.8 days mindfulness meditation group, 7.0 days active control). Fifty-seven (63%) women completed 6-month follow-up, and 75 (83%) women completed at least one postrandomisation follow-up. The 95% CIs for clinical outcomes were consistent with no benefit from the mindfulness meditation app; for example, mean differences in pain acceptance scores at 60 days (higher scores are better) were -2.3 (mindfulness meditation vs usual care, 95% CI: -6.6 to 2.0) and -4.0 (mindfulness meditation vs active control, 95% CI: -8.1 to 0.1)., Conclusions: Despite high recruitment and adequate follow-up rates, demonstrating feasibility, the extremely low adherence suggests a definitive randomised trial of the mindfulness meditation app used in this study is not warranted. Future research should focus on improving patient engagement., Trial Registration Numbers: NCT02721108; ISRCTN10925965; Results., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Schizophrenia patients frequently display an array of abnormal bodily phenomena (ABPs). There is literature to suggest that the presence of ABPs may be representative of a fundamental disruption of the embodied and prereflexive state of selfhood and hence be relevant for the development of schizophrenia spectrum disorders. ABPs have been considered as trait features of vulnerability to psychosis and may have value as potential markers for early detection, target symptoms for prevention and predictors of clinical outcomes. This longitudinal cohort study aimed to explore: (1) the prevalence of ABPs in first episode psychosis, (2) their longitudinal stability, (3) how ABPs compare with data from patients with enduring psychosis, and (4) how aspects of disorders of self-experience (DSEs) and ABPs and the corresponding instruments relate to each other. Sixteen patients were recruited from an early intervention in psychosis service. They were assessed with a series of structured and semi-structured interviews at point of entry, after 6 months and 12 months of follow-up. A variety of ABPs and DSEs were displayed in all study subjects, associated with high levels of core psychotic symptoms and reduced with treatment over time. Compared with findings of both acute and chronic schizophrenia patients, the prevalence of ABPs seems to be representative of severity and acuteness of the illness. Two factors were identified with stable trait characteristics and might be of predictive value for the course of the illness. Further studies with bigger samples are needed to further test the value of ABPs as early markers of detection and predictors of clinical course. The association between DSEs and ABPs warrants further investigation., (© 2020 S. Karger AG, Basel.)

Molecular spin switches are attractive candidates for controlling the spin polarization developing at the interface between molecules and magnetic metal surfaces 1,2 , which is relevant for molecular spintronics devices 3-5 . However, so far, intrinsic spin switches such as spin-crossover complexes have suffered from fragmentation or loss of functionality following adsorption on metal surfaces, with rare exceptions 6-9 . Robust metal-organic platforms, on the other hand, rely on external axial ligands to induce spin switching 10-14 . Here we integrate a spin switching functionality into robust complexes, relying on the mechanical movement of an axial ligand strapped to the porphyrin ring. Reversible interlocked switching of spin and coordination, induced by electron injection, is demonstrated on Ag(111) for this class of compounds. The stability of the two spin and coordination states of the molecules exceeds days at 4 K. The potential applications of this switching concept go beyond the spin functionality, and may turn out to be useful for controlling the catalytic activity of surfaces 15 .

Diazocines are bridged azobenzenes with superior photophysical properties. In contrast to azobenzenes the Z configuration is thermodynamically stable and the E isomer is metastable. We present a new class of nitrogen bridged diazocines with bathochromically shifted switching wavelengths and remarkably high quantum yields (-NH-CH 2 - bridged diazocine: Φ Z→E = 0.57, Φ E→Z = 0.8). Z to E isomerization is induced by irradiation with blue light, whereas switching back to the Z isomer is accomplished with light in the near-infrared window (up to 740 nm), which is important for medical applications like photopharmacology (deep tissue penetration). Furthermore, substitution at the bridging nitrogen should provide access to widely applicable tricyclic, photoswitchable pharmacophores. The -NAc-CH 2 - bridged derivative is soluble in water, and all photophysical properties (conversion rates, quantum yields, and thermal half-lives) are largely retained. Hence, this diazocine is an ideal photoswitch for applications in biochemical systems and in photopharmacology.

Triazatriangulenium (TATA) and trioxatriangulenium (TOTA) ions are particularly suited systems to mount functional molecules onto atomically flat surfaces such as Au(111). The TATA and TOTA units serve as platforms that absorb onto the surface and form ordered monolayers, while the functional groups are protruding upright and freestanding from the central carbon atoms. Azobenzene derivatized TATA's are known to exhibit extremely fast cis → trans isomerization on metal surfaces, via a peculiar non-adiabatic singlet→triplet→singlet mechanism. We now prepared norbornadienes (NBD) and quadricyclanes (QC) attached to TATA and TOTA platforms which can be used to check if these accelerated rates and the spin change mechanism also apply to [2 + 2] cycloreversions (QC→NBD).

Recently, it has been shown that the thermochemical cis → trans isomerization of azobenzenes is accelerated by a factor of more than 1000 by electronic coupling to a gold surface via a conjugated system with 11 bonds and a distance of 14 Å. The corresponding molecular architecture consists of a platform (triazatriangulenium (TATA)) which adsorbs on the gold surface, with an acetylene spacer standing upright, like a post in the middle of the platform and the azobenzene unit mounted on top. The rate acceleration is due to a very peculiar thermal singlet-triplet-singlet mechanism mediated by bulk gold. To investigate this mechanism further and to examine scope and limitation of the "spin-switch catalysis" we now prepared analogous diazocine systems. Diazocines, in contrast to azobenzenes, are stable in the cis -configuration. Upon irradiation with light of 405 nm the cis -configuration isomerizes to the trans -form, which slowly returns back to the stable cis -isomer. To investigate the thermal trans → cis isomerization as a function of the conjugation to the metal surface, we connected the acetylene spacer in meta (weak conjugation) and in para (strong conjugation) position. Both isomers form ordered monolayers on Au(111) surfaces.

We report the synthesis of five dicarboxylic acid-substituted dipolar molecular rotors for the use as linker molecules in metal-organic frameworks (MOFs). The rotor molecules exhibit very low rotational barriers and decent to very high permanent, charge free dipole moments, as shown by density functional theory calculations on the isolated molecules. Four rotors are fluorescent in the visible region. The linker designs are based on push-pull-substituted phenylene cores with ethynyl spacers as rotational axes, functionalized with carboxylic acid groups for implementation in MOFs. The substituents at the phenylene core are chosen to be small to leave rotational freedom in solids with confined free volumes. The dipole moments are generated by electron-donating substituents (benzo-1,3-dioxole, benzo-1,4-dioxane, or benzo-2,1,3-thiadiazole annelation) and withdrawing substituents (difluoro, or dicyano substitution) at the opposite positions of the central phenylene core. A combination of 1,4-dioxane annelation and dicyano substitution generates a theoretically predicted, very high dipole moment of 10.1 Debye. Moreover, the molecules are sufficiently small to fit into cavities of 10 Å 3 . Hence, the dipolar rotors should be ideally suited as linkers in MOFs with potential applications as ferroelectric materials and for optical signal processing.

We report on a very unusual case of surface catalysis involving azobenzenes in contact with a Au(111) surface. A rate acceleration of the cis-trans isomerization on gold up to a factor of 1300 compared to solution is observed. By using carefully designed molecular frameworks, the electronic coupling to the surface can be systematically tuned. The isomerization kinetics of molecules with very weak coupling to the metal is similar to that found in solution. For their counterparts with strong coupling, the relaxation rate is shown to depend on the spin-density distribution in the triplet states of the molecules. This suggests that an intersystem crossing is involved in the relaxation process. Aside from their impact on catalytic processes, these effects could be used to trigger reactions over long distances., (© 2019 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.)

Background: Clinical outcomes for patients with heterogeneous somatoform disorder (bodily distress disorder, including medically unexplained symptoms) are suboptimal, new treatments are required to improve acceptance. Body-oriented psychological therapy approaches have been identified as potentially beneficial additions to the portfolio of treatments. This study was aiming to assess the acceptability, the potential benefits, and associated change processes of manualised group body psychotherapy (BPT) for outpatients with Somatoform Disorder., Methods: A randomized controlled feasibility trial was carried out with follow-up at 6 months after baseline assessments using the Primary Health Questionnaire (PHQ), Somatic Symptom Screening Scale (SOMS-7), quality of life ratings (Short-Form Health Survey-36; SF-36) and body image measures (Dresden Body Image Questionnaire). Acceptance was assessed with the Helping Alliance Scale (HAS)., Results: A total of 24 patients were recruited to participate. Sixteen patients were randomly assigned to receive either manualised BPT or TAU, eight patients were directly assigned to BPT. Drop-out rates were acceptable, patients reported to be highly satisfied with the group intervention. Somatic symptom levels reduced significantly in the BPT group. Additionally, a significant effect on self-acceptance and the mental component of quality of life was observed., Conclusion: Group body psychotherapy is a feasible and acceptable treatment for patients with somatoform disorder and a larger trial studying the effectiveness of BPT in these patients should be conducted., Trial Registration: Retrospectively registered SRCTN12277345 ; Trial Registraton Date: 27/03/2019.

Fe(III) porphyrins bridged with 1,2,3-triazole ligands were synthesized. Upon deprotonation, the triazolate ion coordinates to the Fe(III) ion, forming an overall neutral high-spin Fe(III) porphyrin in which the triazolate serves both as an axial ligand and as the counterion. The second axial coordination site is activated for coordination and binds p-methoxypyridine, forming a six-coordinate low-spin complex. Upon addition of a phenylazopyridine as a photodissociable ligand, the spin state of the complex can be reversibly switched with ultraviolet and visible light. The system provides the basis for the development of switchable catalase- and peroxidase-type catalysts and molecular spin switches.

A Diels-Alder strategy is reported to synthesize the complete set of hydroporphyrins: chlorins, bacteriochlorins, isobacteriochlorins, and pyrrocorphins. Porphyrins and Ni-porphyrins react with isobenzofuran in very high yields at 70 °C to form the corresponding chlorins. Electron-deficient porphyrins react with a second equivalent of isobenzofuran yielding exclusively bacteriochlorin (82%), and Ni-porphyrin gives only isobacteriochlorin (99%). All cycloadditions are completely regio- and stereoselective. The regiochemistry is correctly predicted using the ACID method.

The frequent association of depression with somatic symptoms suggests that body psychotherapy may be an appropriate therapeutic intervention for people with chronic depression. Using a subset of twenty-three participants from a randomized controlled trial that had demonstrated the effectiveness of such an intervention in reducing depressive symptoms, the present study investigated whether it may also impact aspects of construing which have been associated with depression. Patients presenting with chronic depression were randomly allocated to a treatment group or a waiting list group, which received body psychotherapy after a period on a waiting list. Correlations between repertory grid, questionnaire, and visual analogue measures indicated that depression and bodily dissatisfaction were associated with features of the content and structure of construing. There were no significant changes while patients were on the waiting list, but during treatment reduction in depression and bodily dissatisfaction, together with increase in self-esteem and quality of life, were accompanied by an increase in the salience of construing of the bodily self., (Copyright © 2018.

A number of singly (180°) twisted, largely single-stranded and thus conformationally rather fragile, Möbius molecules have been synthesized within the last 15 years, which are aromatic with 4 n electrons, thus violating the Hückel rule. Annulenes with significantly higher twist ( e.g. 540°) that retain a full cyclic conjugation path have been elusive, mainly because of the high strain and loss of orbital overlap. Recently, a topological strategy was devised to project the "twist" into "writhe", thus reducing the strain. However, orbital overlap was still severely reduced within the flexible building blocks. We now present a single and a triple twisted annulene with fully conjugated peripheries. They are unique in their pronounced band shape and conformational robustness as they are made up of three fully kata-condensed [5]helicene fragments. The triple twisted molecule exhibits a strong diatropic ring current in the outer periphery, even though the π system includes 4 n electrons. The diatropic current is counterbalanced by a paratropic current in the σ system, resulting in no net manifestation of macrocyclic aromaticity. The key step of the synthesis of both Möbius compounds is a Perkin condensation of complementary bifunctional bismaleates leading to a flexible macrocycle containing alternating benzene and biphenyl fragments. Subsequent photocyclization yields a separable mixture of rigid diastereomeric tris-helicene macrocycles of the above topologies.

Aims and method New collaborative care models with an emphasis on primary care are required for long-term management of patients with severe and enduring mental illness (SMI). We conducted a descriptive evaluation of clinical outcomes of the first 3 years of a novel enhanced primary care (EPC) service. Data from 2818 patients and staff survey results were analysed. Results 2310 patients were discharged to EPC (508 not assessed as clinically suitable or patients/general practitioners declined the transfer); mean length of stay with secondary care service of the cohort was 9.8 years (range 0-24). 717 patients (31%) have been discharged to primary care only out of the EPC services and 233 patients (10%) have been transferred back to secondary care. Patient and staff satisfaction with the new EPC model was high. No severe untoward incidents were recorded. Clinical implications The data suggest that EPC can be safely provided for a significant proportion of patients with SMI, who traditionally received long-term secondary care support. The novel EPC model can be utilised as a template for the provision of cost-effective, recovery-oriented and non-stigmatising care in the community., Competing Interests: Declaration of interest None.

Aromaticity of photoexcited molecules is an important concept in organic chemistry. Its theory, Baird's rule for triplet aromaticity since 1972 gives the rationale of photoinduced conformational changes and photochemical reactivities of cyclic π-conjugated systems. However, it is still challenging to monitor the dynamic structural change induced by the excited-state aromaticity, particularly in condensed materials. Here we report direct structural observation of a molecular motion and a subsequent packing deformation accompanied by the excited-state aromaticity. Photoactive liquid crystal (LC) molecules featuring a π-expanded cyclooctatetraene core unit are orientationally ordered but loosely packed in a columnar LC phase, and therefore a photoinduced conformational planarization by the excited-state aromaticity has been successfully observed by time-resolved electron diffractometry and vibrational spectroscopy. The structural change took place in the vicinity of excited molecules, producing a twisted stacking structure. A nanoscale torque driven by the excited-state aromaticity can be used as the working mechanism of new photoresponsive materials.

Background: Existing care models for patients with persistent medically unexplained symptoms (MUS) do not adequately address the needs of these patients. New and innovative intervention strategies are necessary to achieve better health and corresponding economic outcomes., Aim: To explore the feasibility of implementing a pragmatic care package that provides primary care treatment for patients with persistent MUS and to evaluate recruitment, retention, and acceptability as well as the potential impact on clinical outcomes and service utilisation., Design & Setting: Prospective cohort intervention study involving a cluster of seven GP surgeries in Newham, East London, providing a 'One-Stop-Shop' primary care treatment service., Method: The care package included: identification, assessment, engagement, psychoeducation, and a choice of group interventions (mindfulness-based stress reduction [MBSR] and body-oriented psychological therapy [BOPT]). Baseline and follow-up data on somatic symptom levels (PHQ-15), health-related quality of life (SF-36, EQ-5D) and service utilisation was analysed., Results: In total, 145 patients were referred and assessed for eligibility, and 93 were included in the study. Participants engaged well with different components of the care package and gained significant improvements in somatic symptom levels with corresponding increases of quality-of-life ratings and a reduction in healthcare utilisation (GP contacts and referrals to specialist services) as well as associated healthcare costs., Conclusion: The primary care treatment package can be successfully implemented in primary care at a relatively low cost and easily adopted into routine care. The body-oriented approach is well accepted by clinicians and patients. Controlled trials should be conducted to test the efficacy of the treatment package., Competing Interests: The authors declare that no competing interests exist.

Diazocines, bridged azobenzenes, exhibit superior photophysical properties compared to parent azobenzenes such as high switching efficiencies, quantum yields, and particularly switching wavelengths in the visible range. Synthesis, however, proceeds with low yields, and derivatives are difficult to prepare. We now present two heterodiazocines which are easier to synthesize, and the general procedures should also provide facile access to derivatives. Moreover, both compounds can be switched with light in the far-red (650 nm). Accessibility and photophysical properties make them ideal candidates for applications such as photoswitchable drugs and functional materials.

Background: The negative symptoms of schizophrenia significantly impact on quality of life and social functioning, and current treatment options are limited. In this study the clinical effectiveness and cost-effectiveness of group body psychotherapy as a treatment for negative symptoms were compared with an active control., Design: A parallel-arm, multisite randomised controlled trial. Randomisation was conducted independently of the research team, using a 1 : 1 computer-generated sequence. Assessors and statisticians were blinded to treatment allocation. Analysis was conducted following the intention-to-treat principle. In the cost-effectiveness analysis, a health and social care perspective was adopted., Eligibility Criteria: age 18-65 years; diagnosis of schizophrenia with symptoms present at > 6 months; score of ≥ 18 on Positive and Negative Syndrome Scale (PANSS) negative symptoms subscale; no change in medication type in past 6 weeks; willingness to participate; ability to give informed consent; and community outpatient., Exclusion Criteria: inability to participate in the groups and insufficient command of English., Settings: Participants were recruited from NHS mental health community services in five different Trusts. All groups took place in local community spaces., Interventions: Control intervention: a 10-week, 90-minute, 20-session group beginners' Pilates class, run by a qualified Pilates instructor. Treatment intervention: a 10-week, 90-minute, 20-session manualised group body psychotherapy group, run by a qualified dance movement psychotherapist., Outcomes: The primary outcome was the PANSS negative symptoms subscale score at end of treatment. Secondary outcomes included measures of psychopathology, functional, social, service use and treatment satisfaction outcomes, both at treatment end and at 6-month follow-up., Results: A total of 275 participants were randomised (140 body psychotherapy group, 135 Pilates group). At the end of treatment, 264 participants were assessed (137 body psychotherapy group, 127 Pilates group). The adjusted difference in means of the PANSS negative subscale at the end of treatment was 0.03 [95% confidence interval (CI) -1.11 to 1.17], showing no advantage of the intervention. In the secondary outcomes, the mean difference in the Clinical Assessment Interview for negative symptoms expression subscale at the end of treatment was 0.62 (95% CI -1.23 to 0.00), and in extrapyramidal movement disorder symptoms -0.65 (95% CI -1.13 to -0.16) at the end of treatment and -0.58 (95% CI -1.07 to -0.09) at 6 months' follow-up, showing a small significant advantage of body psychotherapy. No serious adverse events related to the interventions were reported. The total costs of the intervention were comparable with the control, with no clear evidence of cost-effectiveness for either condition., Limitations: Owing to the absence of a treatment-as-usual arm, it is difficult to determine whether or not both arms are an improvement over routine care., Conclusions: In comparison with an active control, group body psychotherapy does not have a clinically relevant beneficial effect in the treatment of patients with negative symptoms of schizophrenia. These findings conflict with the review that led to the current National Institute for Health and Care Excellence guidelines suggesting that arts therapies may be an effective treatment for negative symptoms., Future Work: Determining whether or not this lack of effectiveness extends to all types of art therapies would be informative., Trial Registration: Current Controlled Trials ISRCTN842165587., Funding: This project was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 20, No. 11.
