A brief mindfulness intervention: Effects on trait mindfulness, stress and emotion regulation within a sample of working adults.
Due to increasing demands within employment, the prevalence of work-related stress is becoming more common. Work-related stress has detrimental effects for the individual suffering and their employer, indicating a need for interventions to reduce stress. Previous research has found mindfulness to offer promising results. However, the commitment required and the duration of a typical mindfulness course could be considered impractical due to busy work schedules.This study was therefore interested in the effectiveness of a brief mindfulness intervention, delivered via a mobile phone-based application. Forty-seven employees were allocated randomly to either a mindfulness group (n = 24) or an active control group (n = 23). The study investigated if a brief ten-day mindfulness intervention could increase trait mindfulness, decrease stress and decrease difficulties in emotion regulation within a sample of working adults.From pre to post-intervention, significant increases in self-reported trait mindfulness were identified within the mindfulness group and also significant decreases in self-reported stress and difficulties in emotion regulation. The control group displayed non-significant changes from pre to post control group activities for all the tested variables. This study adds to the little research conducted on mobile phone interventions and also addresses real life implications and directions for future research
FC-GAGA: Fully Connected Gated Graph Architecture for Spatio-Temporal Traffic Forecasting
Forecasting of multivariate time-series is an important problem that has
applications in traffic management, cellular network configuration, and
quantitative finance. A special case of the problem arises when there is a
graph available that captures the relationships between the time-series. In
this paper we propose a novel learning architecture that achieves performance
competitive with or better than the best existing algorithms, without requiring
knowledge of the graph. The key element of our proposed architecture is the
learnable fully connected hard graph gating mechanism that enables the use of
the state-of-the-art and highly computationally efficient fully connected
time-series forecasting architecture in traffic forecasting applications.
Experimental results for two public traffic network datasets illustrate the
value of our approach, and ablation studies confirm the importance of each
element of the architecture. The code is available here:

The role of emotion regulation for coping with school-based peer-victimisation in late childhood
The current research examined the role of two emotion regulation processes, cognitive reappraisal and emotion suppression, on maladaptive victimisation coping following school-based peer-victimisation in late childhood (n = 443). The relationship between emotion regulation and maladaptive coping was also tested for serial mediation effects, linking peer-victimisation and school loneliness. Results showed that poor emotion regulation in children was positively associated with maladaptive peer-victimisation coping. Moreover, the relationship between cognitive reappraisal and maladaptive coping was found to mediate the relationship between peer-victimisation experiences and school loneliness. These findings have implications for the development of school-based peer-victimisation intervention strategies that focus on improving children's emotional competencies
The chromospherically--active binary CF Tuc revisited
New high-resolution spectra, of the chromospherically active binary system CF
Tuc, taken at the Mt. John University Observatory in 2007, were analyzed using
two methods: cross-correlation and Fourier--based disentangling. As a result,
new radial velocity curves of both components were obtained. The resulting
orbital elements of CF Tuc are: = AU,
= AU, =
, and = . The cooler
component of the system shows H and CaII H & K emissions. Our
spectroscopic data and recent light curves were solved simultaneously
using the Wilson-Devinney code. A dark spot on the surface of the cooler
component was assumed to explain large asymmetries observed in the light
curves. The following absolute parameters of the components were determined:
= , = ,
= , = ,
= and = . The
orbital period of the system was studied using the O-C analysis. The O-C
diagram could be interpreted in terms of either two abrupt changes or a
quasi-sinusoidal form superimposed on a downward parabola. These variations are
discussed by reference to the combined effect of mass transfer and mass loss,
the Applegate mechanism and also a light-time effect due to the existence of a
massive third body (possibly a black hole) in the system. The distance to CF
Tuc was calculated to be pc from the dynamic parallax, neglecting
interstellar absorption, in agreement with the Hipparcos value.Comment: 33 pages, 10 figures, accepted for publication by MNRA
Treating to target in psoriatic arthritis: assessing real-world outcomes and optimising therapeutic strategy for adults with psoriatic arthritis-study protocol for the MONITOR-PsA study, a trials within cohorts study design.
BACKGROUND: The Tight Control of psoriatic arthritis (TICOPA) trial confirmed improved clinical outcomes with a treat to target (T2T) strategy in psoriatic arthritis (PsA). This consisted of 4-weekly review and escalation of 'step up' therapy (single disease modifying therapy (DMARD), combination DMARDs and then biologics) based on remission criteria. Based on this, a T2T approach is supported by European PsA treatment recommendations. However, it is not commonly implemented in routine care primarily due to feasibility and cost concerns. In the TICOPA trial, the same treatment regime was used for all participants regardless of their disease profile. Despite the recognition of PsA as a highly heterogeneous condition, no studies have tailored which drugs are used depending on disease severity. The cohort will establish real world outcomes for the T2T approach in PsA and also form the basis of a trials within cohorts (TWiCs) design to test alternative therapeutic approaches within embedded clinical trials providing an evidence base for treatment strategy in PsA. METHODS: The Multicentre Observational Initiative in Treat to target Outcomes in Psoriatic Arthritis (MONITOR-PsA) cohort will apply a T2T approach within routine care. It will recruit newly diagnosed adult patients with PsA starting systemic therapies. The cohort is observational allowing routine therapeutic care within NHS clinics but a T2T approach will be supported when monitoring treatment within the cohort. Eligible participants will be adults (≥18 years) with active PsA with ≥ 1 tender or swollen joints or enthesis who have not previously had treatment with DMARDs for articular disease. DISCUSSION: This study is the first TWiC designed to support a fully powered randomised drug trial. The results from the observational cohort will be compared with those observed in the TICOPA trial investigating the clinical effectiveness and health care costs of the pragmatic T2T approach. Nested trials will provide definitive RCT evidence establishing the optimal management of PsA within the T2T approach. The TWiCs design allows robust generalizability to routine healthcare, avoids disappointment bias, aids recruitment and in future will allow assessment of longer-term outcomes.

Effect of a 2-week interruption in methotrexate treatment on COVID-19 vaccine response in people with immune-mediated inflammatory diseases (VROOM study): a randomised, open label, superiority trial
Background
Methotrexate is the first-line treatment for immune-mediated inflammatory diseases and reduces vaccine-induced immunity. We evaluated if a 2-week interruption of methotrexate treatment immediately after COVID-19 booster vaccination improved antibody response against the S1 receptor binding domain (S1-RBD) of the SARS-CoV-2 spike protein and live SARS-CoV-2 neutralisation compared with uninterrupted treatment in patients with immune-mediated inflammatory diseases.
Method
We did a multicentre, open-label, parallel-group, randomised, superiority trial in secondary-care rheumatology and dermatology clinics in 26 hospitals in the UK. Adults (aged ≥18 years) with immune-mediated inflammatory diseases taking methotrexate (≤25 mg per week) for at least 3 months, who had received two primary vaccine doses from the UK COVID-19 vaccination programme were eligible. Participants were randomly assigned (1:1) using a centralised validated computer program, to temporarily suspend methotrexate treatment for 2 weeks immediately after COVID-19 booster vaccination or continue treatment as usual. The primary outcome was S1-RBD antibody titres 4 weeks after COVID-19 booster vaccination and was assessed masked to group assignment. All randomly assigned patients were included in primary and safety analyses. This trial is registered with ISRCTN, ISRCTN11442263; following a pre-planned interim analysis, recruitment was stopped early.
Finding
Between Sept 30, 2021, and March 7, 2022, we screened 685 individuals, of whom 383 were randomly assigned: to either suspend methotrexate (n=191; mean age 58·8 years [SD 12·5], 118 [62%] women and 73 [38%] men) or to continue methotrexate (n=192; mean age 59·3 years [11·9], 117 [61%] women and 75 [39%] men). At 4 weeks, the geometric mean S1-RBD antibody titre was 25 413 U/mL (95% CI 22 227–29 056) in the suspend methotrexate group and 12 326 U/mL (10 538–14 418) in the continue methotrexate group with a geometric mean ratio (GMR) of 2·08 (95% CI 1·59–2·70; p<0·0001). No intervention-related serious adverse events occurred.
Interpretation
2-week interruption of methotrexate treatment in people with immune-mediated inflammatory diseases enhanced antibody responses after COVID-19 booster vaccination that were sustained at 12 weeks and 26 weeks. There was a temporary increase in inflammatory disease flares, mostly self-managed. The choice to suspend methotrexate should be individualised based on disease status and vulnerability to severe outcomes from COVID-19.

Comparable disparity in the appendicular skeleton across the fish-tetrapod transition, and the morphological gap between fish and tetrapod postcrania
Appendicular skeletal traits are used to quantify changes in morphological disparity and morphospace occupation across the fish-tetrapod transition, and to explore the informativeness of different data partitions in phylogeny reconstruction. Anterior appendicular data yield trees that differ little from those built from the full character set, whilst posterior appendicular data result in considerable loss of phylogenetic resolution and tree branch rearrangements. Overall, there is significant incongruence in the signals associated with pectoral and pelvic data. The appendicular skeletons of fish and tetrapods attain similar levels of morphological disparity (at least when data are rarefied at the maximum sample size for fish in our study) and occupy similarly sized regions of morphospace. However, fish appear more dispersed in morphospace than tetrapods do. All taxa show a heterogeneous distribution in morphospace, and there is a clear separation between fish and tetrapods despite the presence of several evolutionarily intermediate taxa

Morgawr: an experimental Bronze Age-type sewn-plank craft based on the Ferriby boats
Photographs and a link to a video showing the construction and launch of "Morgawr" can also be found in ORE: http://hdl.handle.net/10871/14703This paper reports on the construction of a full-scale Bronze Age-type sewn-plank boat based on the Ferriby boats. The boat, which was named Morgawr, was constructed in the National Maritime Museum Cornwall in Falmouth, England, during 2012 and the first months of 2013, as part of a larger exhibition in the museum. This paper provides the background and context of the project, describes the process of building the craft, and reflects in particular on differences between Morgawr and the ‘hypothetical reconstruction of a complete sewn-plank boat’ published in 1990 by Ted Wright and John Coates which formed the basis for this project.Arts and Humanities Research Council (AHRC
Cost-utility analysis of molnupiravir plus usual care versus usual care alone as early treatment for community-based adults with COVID-19 and increased risk of adverse outcomes in the UK PANORAMIC trial
BACKGROUND: The cost-effectiveness of molnupiravir, an oral antiviral for early treatment of SARS-CoV-2, has not been established in vaccinated populations.
AIM: To evaluate the cost-effectiveness of molnupiravir relative to usual care alone among mainly vaccinated community-based people at higher risk of severe outcomes from COVID-19 over six months.
DESIGN AND SETTING: Economic evaluation of the PANORAMIC trial in the UK.
METHOD: A cost-utility analysis that adopted a UK National Health Service and personal social services perspective and a six-month time horizon was performed using PANORAMIC trial data. Cost-effectiveness was expressed in terms of incremental cost per quality-adjusted life year (QALY) gained. Sensitivity and subgroup analyses assessed the impacts of uncertainty and heterogeneity. Threshold analysis explored the price for molnupiravir consistent with likely reimbursement.
RESULTS: In the base case analysis, molnupiravir had higher mean costs of £449 (95% confidence interval [CI] 445 to 453) and higher mean QALYs of 0.0055 (95% CI 0.004 to 0.007) than usual care (mean incremental cost per QALY of £81190). Sensitivity and subgroup analyses showed similar results, except those aged ≥75 years with a 55% probability of being cost-effective at a £30000 per QALY threshold. Molnupiravir would have to be priced around £147 per course to be cost-effective at a £15000 per QALY threshold.
CONCLUSION: Molnupiravir at the current cost of £513 per course is unlikely to be cost-effective relative to usual care over a six-month time horizon among mainly vaccinated COVID-19 patients at increased risk of adverse outcomes, except those aged ≥75 years
