Vortex-loop renormalization is used to compute the specific heat of superfluid ^{4}He near the lambda point at various pressures up to 26 bars. The input parameters are the pressure dependence of T_{λ} and the superfluid density, which determine the nonuniversal parameters of the vortex core energy and core size. The results for the specific heat are found to be in good agreement with experimental data, matching the expected universal pressure dependence to within about 5%. The nonuniversal critical amplitude of the specific heat is found to be in reasonable agreement, a factor of four larger than the experiments. We point out problems with recent Gross-Pitaevskii simulations that claimed the vortex-loop percolation temperature did not match the critical temperature of the superfluid phase transition.

The offender personality disorder (OPD) Pathway is a network of services across prison, health and community settings in England and Wales providing psychological support for high-risk people who have offended and are thought to have a personality disorder. As part of a national evaluation of the Pathway, semi-structured interviews were carried out with 36 Pathway users to determine their views about their experiences in these services; and whether and how these impacted on their psychological wellbeing. Framework analysis was used to analyze the data. Participants reported positive therapeutic relationships with staff; improved psychological wellbeing; and for some, a shift away from antisocial toward more pro-social identities. They also described a negative impact of staff turnover and uncertainty about the role of prison officers and psychologists within prison services. Pathway services are able to engage individuals who have not previously engaged with services. Constancy of staff is fundamental to the Pathway. [ABSTRACT FROM AUTHOR]

Summary: Chemsex occurs primarily among gay, bisexual and other men who have sex with men (GBMSM), and there is evidence of a subgroup of users who carry out chemsex-related criminal offences and experience harm. Challenges with chemsex can present to various settings; there are concerns that harm is increasing, including at interfaces between health, social care and criminal justice systems. The UK response to date has lacked a coordinated approach. An expert reference group was convened to share chemsex knowledge, articulate priorities for research and pathway development, and foster collaborative working between agencies. It made three key recommendations: develop and increase training and awareness across all services; implement a coordinated research programme with the development of a common data-set and assessment tool to fully characterise population-level needs; develop a professional network to share information, provide professional support and act as a knowledge hub. There was support for a unified multi-agency strategy incorporating the priorities identified as overarching principles. [ABSTRACT FROM AUTHOR]

Summary: We argue that editorial independence, through robust practice of publication ethics and research integrity, promotes good science and prevents bad science. We elucidate the concept of research integrity, and then discuss the dimensions of editorial independence. Best practice guidelines exist, but compliance with these guidelines varies. Therefore, we make recommendations for protecting and strengthening editorial independence. [ABSTRACT FROM AUTHOR]

This article summarises the BJPsych Bulletin 2024 special edition on mental health in criminal justice and correctional settings. The edition considers issues across a range of settings, including police custody, the courts and prisons, as well as considering wider international questions and systems within the field. In this edition, we assert the right of the individual to healthcare services that should be available, accessible, acceptable and of good quality. Psychiatry must play a significant role in shaping this debate as it moves forward. [ABSTRACT FROM AUTHOR]

Background: In England, court‐based mental health liaison and diversion (L&D) services work across courts and police stations to support those with severe mental illness and other vulnerabilities. However, the evidence around how such services support those with neurodevelopmental disorders (NDs) is limited. Aims: This study aimed to evaluate, through the lens of court and clinical staff, the introduction of a L&D service for defendants with NDs, designed to complement the existing L&D service. Methods: A realist evaluation was undertaken involving multiple agencies based within an inner‐city Magistrates' Court in London, England. We developed a logic model based on the initial programme theory focusing on component parts of the new enhanced service, specifically training, screening, signposting and interventions. We conducted semi‐structured interviews with the court staff, judiciary and clinicians from the L&D service. Results: The L&D service for defendants with NDs was successful in identifying and supporting the needs of those defendants. Benefits of this service included knowledge sharing, awareness raising and promoting good practice such as making reasonable adjustments. However, there were challenges for the court practitioners and clinicians in finding and accessing local specialist community services. Conclusion: A L&D service developed for defendants with NDs is feasible and beneficial to staff and clinicians who worked in the court setting leading to good practice being in place for the defendants. Going forward, a local care pathway would need to be agreed between commissioners and stakeholders including the judiciary to ensure timely and equitable access to local services by both defendants and practitioners working across diversion services for individuals with NDs.
