Background Quality smoking data is crucial for assessing smoking-related health risk and eligibility for interventions related to that risk. Smoking information collected in primary care practices (PCPs) is a major data source; however, little is known about the PCP smoking data quality. This project compared PCP smoking data to that collected in the Māori and Pacific Abdominal Aortic Aneurysm (AAA) screening programme. Methods A two stage review was conducted. In Stage 1, data quality was assessed by comparing the PCP smoking data recorded close to AAA screening episodes with the data collected from participants at the AAA screening session. Inter-rater reliability was analysed using Cohen’s kappa scores. In Stage 2, an audit of longitudinal smoking status was conducted, of a subset of participants potentially misclassified in Stage 1. Data were compared in three groups: current smoker (smoke at least monthly), ex-smoker (stopped > 1 month ago) and never smoker (smoked < 100 cigarettes in lifetime). Results Of the 1841 people who underwent AAA screening, 1716 (93%) had PCP smoking information. Stage 1 PCP smoking data showed 82% concordance with the AAA data (adjusted kappa 0.76). Fewer current or ex-smokers were recorded in PCP data. In the Stage 2 analysis of discordant and missing data ( N  = 313), 212 were enrolled in the 29 participating PCPs, and of these 13% were deceased and 41% had changed PCP. Of the 93 participants still enrolled in the participating PCPs, smoking status had been updated for 43%. Data on quantity, duration, or quit date of smoking were largely missing in PCP records. The AAA data of ex-smokers who were classified as never smokers in the Stage 2 PCP data ( N  = 27) showed a median smoking cessation duration of 32 years (range 0–50 years), with 85% ( N  = 23) having quit more than 15 years ago. Conclusions PCP smoking data quality compared with the AAA data is consistent with international findings. PCP data captured fewer current and ex-smokers, suggesting ongoing improvement is important. Intervention programmes based on smoking status should consider complementary mechanisms to ensure eligible individuals are not missed from programme invitation.

Abstract This study explores how a school wharekai (communal dining hall) implementing the Ka Ora, Ka Ako Healthy School Lunch Programme operates as a multidimensional health promotion setting that fosters student capabilities beyond nutrition. Using a qualitative approach grounded in mātauranga Māori (Māori knowledge) and community-based participatory research, we conducted focus groups with 22 students and semi-structured interviews with 12 staff members to examine how the wharekai promotes wellbeing. Findings show that the wharekai provides a culturally responsive environment where three interrelated capabilities flourish: self-management, interpersonal relationships, and community participation. Through daily routines and authentic roles in food preparation, students practise responsibility, initiative, and cooperation. Shared meals strengthen tuakana–teina (peer) relationships and build trust between students and staff, while collective activities foster belonging, reciprocity, and sustainability. Conceptualizing food spaces through cultural frameworks such as the wharekai demonstrates how school food programmes can simultaneously address food insecurity and create transformative learning environments. This study highlights how culturally grounded, settings-based approaches can integrate nutritional, social, and relational dimensions of health promotion, reimagining school food provision as a holistic, capability-building practice that enhances individual and collective wellbeing.

ObjectivesThis study reports preliminary findings on the prevalence of, and factors associated with, mental health and well-being outcomes of healthcare workers during the early months (April–June) of the COVID-19 pandemic in the UK.MethodsPreliminary cross-sectional data were analysed from a cohort study (n=4378). Clinical and non-clinical staff of three London-based NHS Trusts, including acute and mental health Trusts, took part in an online baseline survey. The primary outcome measure used is the presence of probable common mental disorders (CMDs), measured by the General Health Questionnaire. Secondary outcomes are probable anxiety (seven-item Generalised Anxiety Disorder), depression (nine-item Patient Health Questionnaire), post-traumatic stress disorder (PTSD) (six-item Post-Traumatic Stress Disorder checklist), suicidal ideation (Clinical Interview Schedule) and alcohol use (Alcohol Use Disorder Identification Test). Moral injury is measured using the Moray Injury Event Scale.ResultsAnalyses showed substantial levels of probable CMDs (58.9%, 95% CI 58.1 to 60.8) and of PTSD (30.2%, 95% CI 28.1 to 32.5) with lower levels of depression (27.3%, 95% CI 25.3 to 29.4), anxiety (23.2%, 95% CI 21.3 to 25.3) and alcohol misuse (10.5%, 95% CI 9.2 to 11.9). Women, younger staff and nurses tended to have poorer outcomes than other staff, except for alcohol misuse. Higher reported exposure to moral injury (distress resulting from violation of one’s moral code) was strongly associated with increased levels of probable CMDs, anxiety, depression, PTSD symptoms and alcohol misuse.ConclusionsOur findings suggest that mental health support for healthcare workers should consider those demographics and occupations at highest risk. Rigorous longitudinal data are needed in order to respond to the potential long-term mental health impacts of the pandemic.

Selenium, a trace element that is fundamental to human health, is incorporated into some proteins as selenocysteine (Sec), generating a family of selenoproteins. Sec incorporation is mediated by a multiprotein complex that includes Sec insertion sequence-binding protein 2 (SECISBP2; also known as SBP2). Here, we describe subjects with compound heterozygous defects in the SECISBP2 gene. These individuals have reduced synthesis of most of the 25 known human selenoproteins, resulting in a complex phenotype. Azoospermia, with failure of the latter stages of spermatogenesis, was associated with a lack of testis-enriched selenoproteins. An axial muscular dystrophy was also present, with features similar to myopathies caused by mutations in selenoprotein N (SEPN1). Cutaneous deficiencies of antioxidant selenoenzymes, increased cellular ROS, and susceptibility to ultraviolet radiation-induced oxidative damage may mediate the observed photosensitivity. Reduced levels of selenoproteins in peripheral blood cells were associated with impaired T lymphocyte proliferation, abnormal mononuclear cell cytokine secretion, and telomere shortening. Paradoxically, raised ROS in affected subjects was associated with enhanced systemic and cellular insulin sensitivity, similar to findings in mice lacking the antioxidant selenoenzyme glutathione peroxidase 1 (GPx1). Thus, mutation of SECISBP2 is associated with a multisystem disorder with defective biosynthesis of many selenoproteins, highlighting their role in diverse biological processes.

Introduction: Pancreatic ductal adenocarcinoma (PDAC) remains a leading cause of cancer-related mortality. Radiological distinctions between borderline resectable (BR) and locally advanced disease (LA) are increasingly recognised as imperfect when considered without dynamic assessment. Neoadjuvant therapy (NAT) improves outcomes through tumour downstaging and early treatment of occult metastatic disease, but the optimal NAT strategy, particularly in BR disease, remains uncertain. Published data evaluating combined systemic anti-cancer therapies (SACT) with or without chemoradiation (CRT) are limited and heterogeneous. Methods: This is a single-centre retrospective analysis of 44 patients with BR PDAC and a comparator cohort of 121 patients with LA PDAC treated with a total neoadjuvant approach of SACT with or without CRT and surgical resection between June 2017 and September 2022. Results: Median overall survival (OS) did not differ significantly between BR and LA disease (18 vs. 16 months, p = 0.14). Following NAT, 47.7% of BR and 18.1% of LA patients were anatomically suitable for surgical resection. Among unresected BR and LA patients, those treated with CRT in addition to SACT had a median OS of 18 and 21 months respectively. In the resected subgroup, resection margin status was the primary factor associated with survival; with R0 resection conferring a substantial OS advantage over R1, irrespective of initial BR/LA classification as diagnosis (47 vs. 22 months, p < 0.001). Conclusions: Despite anatomical differences at diagnosis, BR and LA PDAC demonstrated comparable survival outcomes when treated with total neoadjuvant strategies in this cohort. These findings challenge traditional radiological staging-based treatment paradigms and confirm that a margin-negative surgical resection offered the greatest opportunity for long-term survival for BR/LA PDAC patients.

Evidence shows that regular physical activity is enhanced by supporting environment. Studies are needed to integrate research evidence into health enhancing, cross-sector physical activity (HEPA) policy making. This article presents the rationale, study design, measurement procedures and the initial results of the first phase of six European countries in a five-year research project (2011–2016), REsearch into POlicy to enhance Physical Activity (REPOPA). REPOPA is programmatic research; it consists of linked studies; the first phase studied the use of evidence in 21 policies in implementation to learn more in depth from the policy making process and carried out 86 qualitative stakeholder interviews. The second, ongoing phase builds on the central findings of the first phase in each country; it consists of two sets of interventions: game simulations to study cross-sector collaboration and organizational change processes in the use of evidence and locally tailored interventions to increase knowledge integration. The results of the first two study phases will be tested and validated among policy makers and other stakeholders in the third phase using a Delphi process. Initial results from the first project phase showed the lack of explicit evidence use in HEPA policy making. Facilitators and barriers of the evidence use were the availability of institutional resources and support but also networking between researchers and policy makers. REPOPA will increase understanding use of research evidence in different contexts; develop guidance and tools and establish sustainable structures such as networks and platforms between academics and policy makers across relevant sectors.

Background The gaps observed between the use of research evidence and policy have been reported to be based on the different methods of using research evidence in policymaking by researchers and actual policymakers. Some policies and policymaking processes may therefore be particularly well informed by research evidence compared to others. The aims of the present article are to explore the use of research evidence in health-enhancing physical activity (HEPA) policies, identify when research evidence was used, and find what other types of evidence were employed in HEPA policymaking. Methods Multidisciplinary teams from six EU member states analysed the use of research evidence and other kinds of evidence in 21 HEPA policies and interviewed 86 key policymakers involved in the policies. Qualitative content analysis was conducted on both policy documents and interview data. Results Research evidence was mostly used to justify the creation of HEPA policies and, generally, implicitly without citation. The policies analysed used many types of evidence other than citable research. The evidence used in HEPA policies was found to fall into the following categories: societal framework, media, everyday knowledge and intuition, research evidence, and other types of evidence. Conclusions Research evidence seems to be the only type of evidence used in policymaking. Competition between the use of other types of evidence and research evidence is constant due to the various sources of information on the Internet and elsewhere. However, researchers need to understand their role in translating research evidence into policymaking processes.

Quantum key distribution (QKD) is a theoretically proven future-proof secure encryption method that inherits its security from fundamental physical principles. Craft Prospect, working with a number of UK organisations, has been focused on miniaturising the technologies that enable QKD so that they may be used in smaller platforms including nanosatellites. The significant reduction of size, and therefore the cost of launching quantum communication technologies either on a dedicated platform or hosted as part of a larger optical communications will improve potential access to quantum encryption on a relatively quick timescale. The ROKS mission seeks to be among the first to send a QKD payload on a CubeSat into low Earth orbit, demonstrating the capabilities of newly developed modular quantum technologies. The ROKS payload comprises a quantum source module that supplies photons randomly in any of four linear polarisation states fed from a quantum random number generator; an acquisition, pointing, and tracking system to fine-tune alignment of the quantum source beam with an optical ground station; an imager that will detect cloud cover autonomously; and an onboard computer that controls and monitors the other modules, which manages the payload and assures the overall performance and security of the system. Each of these modules have been developed with low SWaP for CubeSats, but with interoperability in mind for other satellite form factors. We present each of the listed components, together with the initial test results from our test bench and the performance of our protoflight models prior to initial integration with the 6U CubeSat platform systems. The completed ROKS payload will be ready for flight at the end of 2022, with various modular components already being baselined for flight and integrated into third party communication missions.
