Published: March 2024

BackgroundSchizophrenia is a chronic mental disorder affecting individuals globally, emphasising the significance of personal recovery in mental healthcare. Understanding the recovery stages and the associated factors can provide essential insights for targeted interventions.AimsThis study aimed to discern the stages of personal recovery in Thai patients with schizophrenia and elucidate the associated factors with each stage.MethodsA multistage sampling technique was employed, selecting 231 patients with schizophrenia from mental health outpatient departments of general and psychiatric hospitals. Data collected from March to May 2023 included screening for psychotic symptoms using the Brief Psychiatric Rating Scale and six self-report questionnaires—Stage of Recovery Scale, Beck Cognitive Insight Scale, Brief Resilience Scale, Family Support, Therapeutic Relationship-Patients Version and Social Support Questionnaire—along with personal data sheets. Pearson correlation and multinomial logistic regression were performed.ResultsThe predominant personal recovery stage among participants was stage 3, ‘living with disabilities’, comprising 42.4% of the participants. Key factors contributing to personal recovery, explaining approximately 38.4% of the variance, included resilience, family support, therapeutic alliance, hospitalisations since onset and recovery-oriented nursing service utilisation. Logit equations for stages 3 and 4 are as follows: stage 3 (living with disability): logit=−4.44+0.74×resilience+0.07×therapeutic alliance+0.02×recovery-oriented nursing service utilisation; stage 4 (living beyond disability): logit=−11.57–0.05×hospitalisation since onset+1.96×resilience+0.11×family support+0.06×therapeutic alliance.ConclusionThe findings emphasise the significance of mental health nursing interventions. In conjunction with recovery-oriented nursing services, strengthening resilience, therapeutic alliances and family support may accelerate personal recovery and reduce hospitalisations among individuals with schizophrenia.

Background
Ultra-short coeliac disease (USCD) is defined as villous atrophy only present in the duodenal bulb (D1) with concurrent positive coeliac serology. We present the first, multicentre, international study of patients with USCD.

Methods
Patients with USCD were identified from 10 tertiary hospitals (6 from Europe, 2 from Asia, 1 from North America and 1 from Australasia) and compared with age-matched and sex-matched patients with conventional coeliac disease.

Findings
Patients with USCD (n=137, median age 27 years, IQR 21–43 years; 73% female) were younger than those with conventional coeliac disease (27 vs 38 years, respectively, p<0.001). Immunoglobulin A-tissue transglutaminase (IgA-tTG) titres at index gastroscopy were lower in patients with USCD versus conventional coeliac disease (1.8×upper limit of normal (ULN) (IQR 1.1–5.9) vs 12.6×ULN (IQR 3.3–18.3), p<0.001).
Patients with USCD had the same number of symptoms overall (median 3 (IQR 2–4) vs 3 (IQR 1–4), p=0.875). Patients with USCD experienced less iron deficiency (41.8% vs 22.4%, p=0.006).
Both USCD and conventional coeliac disease had the same intraepithelial lymphocytes immunophenotype staining pattern; positive for CD3 and CD8, but not CD4.
At follow-up having commenced a gluten-free diet (GFD) (median of 1181 days IQR: 440–2160 days) both USCD and the age-matched and sex-matched controls experienced a similar reduction in IgA-tTG titres (0.5 ULN (IQR 0.2–1.4) vs 0.7 ULN (IQR 0.2–2.6), p=0.312). 95.7% of patients with USCD reported a clinical improvement in their symptoms.

Interpretation
Patients with USCD are younger, have a similar symptomatic burden and benefit from a GFD. This study endorses the recommendation of D1 sampling as part of the endoscopic coeliac disease diagnostic workup.

ObjectiveTo assess health and activities of daily living (ADL) in SARS-CoV-2-positive adults with and without post-COVID-19 condition (PCC) and compare this with negative tested individuals. Furthermore, different PCC case definitions were compared with SARS-CoV-2-negative individuals.MethodsAll adults tested PCR positive for SARS-CoV-2 at the Public Health Service South Limburg (Netherlands) between June 2020 and November 2021 (n=41 780) and matched PCR negative individuals (2:1, on age, sex, year-quarter test, municipality; n=19 875) were invited by email. Health (five-level EuroQol five-dimension (EQ5D) index and EuroQol visual analogue scale (EQVAS)) and ADL impairment were assessed. PCC classification was done using the WHO case definition and five other common definitions.ResultsIn total, 8409 individuals (6381 SARS-CoV-2 positive; 53±15 years; 57% female; 9 (7–11) months since test) were included. 39.4% of positives had PCC by the WHO case definition (EQVAS: 71±20; EQ5D index: 0.800±0.191; ADL impairment: 30 (10–70)%) and perceived worse health and more ADL impairment than negatives, that is, difference of −8.50 points (95% CI −9.71 to −7.29; p<0.001) for EQVAS, which decreased by 1.49 points (95% CI 0.86 to 2.12; p<0.001) in individuals with PCC for each comorbidity present, and differences of −0.065 points (95% CI −0.074 to −0.056; p<0.001) for EQ5D index, and +16.72% (95% CI 15.01 to 18.43; p<0.001) for ADL impairment. Health and ADL impairment were similar in negatives and positives without PCC. Replacing the WHO case definition with other PCC definitions yielded comparable results.ConclusionsIndividuals with PCC have substantially worse health and more ADL impairment than negative controls, irrespective of the case definition. Authorities should inform the public about the associated burden of PCC and enable adequate support.
Correlation of density fluctuation in a magnetized QCD matter near the critical end point

Published: March 2024

AbstractThe dynamical correlation of density fluctuation in quark gluon plasma with a critical end point has been investigated within the scope of the Müller–Israel–Stewart theory in the presence of static ultra-high external magnetic field. The dynamic structure factor of the density fluctuation exhibits three Lorentzian peaks in absence of external magnetic field – a central Rayleigh peak and two Brillouin peaks situated symmetrically on the opposite sides of the Rayleigh peak. The spectral structure displays five peaks in presence of the magnetic field due to the coupling of the magnetic field with the hydrodynamic fields in second-order hydrodynamics. The emergence of the extra peaks is due to the asymmetry in the pressure gradient caused by the external magnetic field in the system. Interestingly, it is observed that near the critical end point, all the Brillouin peaks disappear irrespective of the presence or absence of the external magnetic field.

Published: March 2024

Background: Supracondylar humerus fractures (SHFs) are common paediatric injuries, with high risk of vascular compromise. Some patients present with a ‘pink, pulseless hand’, caused by occlusion of brachial artery flow but with collateral circulation preserving distal perfusion. Management of these patients remains controversial, especially when resources may be limited for prolonged hospitalisation and serial monitoring by skilled staff. The aim of this study is to present the intraoperative findings, surgical procedures done and outcomes at 6 weeks for patients with paediatric supracondylar fractures with a pink pulseless hand. Methods: We retrospectively identified 13 patients who presented to a public hospital between January 2019 and May 2023 with a displaced SHF and pink, pulseless hand. All patients underwent an open reduction with an anterior approach allowing for exploration, protection and repair of neurovascular structures. Distal flow was restored in the brachial artery either with topical lidocaine application, thrombectomy or artery reconstruction. Results: Out of 13 patients, all had intact median nerves and 10 had intact arteries (69%), of which seven were interposed at the fracture site and four were in vasospasm. Of the three patients with true arterial injury (23%), two had a crushed artery and one had thrombosis of the artery. Peripheral pulses were restored within an hour of fracture open reduction in all patients. At final follow-up, a mean 6 weeks postoperatively, all patients had recovered without neurovascular deficit, compartment syndrome or Volkmann ischemic contracture. Conclusions: In resource-limited settings, we recommend performing open exploration and reduction for patients with SHFs with pink, pulseless hand. This approach prevents iatrogenic neurovascular injury during closed reduction attempts, allows for immediate repair of a brachial artery injury and avoids unnecessary hospitalisation and serial monitoring. Level of Evidence: Level IV (Therapeutic)

Published: March 2024

Background: We aim to evaluate the impact of advanced age and sex on postoperative complications and radiographic outcomes after open reduction with internal fixation of distal radius fractures (DRF). Methods: We conducted a retrospective chart review, including all patients who underwent open reduction with internal fixation of a DRF between 2012 and 2018 at a single level 1 trauma centre. We recorded patient age, sex, fracture classification (Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association [AO/OTA]), time from injury to surgical date, surgical duration, diabetes status, tobacco use, illicit drug use, history of osteoporosis, use of adjuvants, fixation type, postoperative radiographic restoration of normal parameters and early complications including loss of reduction within 30 days postoperatively. Advanced age was defined as age greater than 60 years. Results: A total of 521 patients underwent operative treatment – 264 males and 257 females. Males were twice as likely (23.5% vs. 10.1%; p < 0.0001) to sustain a type C3 fracture and be treated with a wrist spanning plate (5.3% vs. 0; p < 0.0001). A larger percentage of elderly patients undergoing operative treatment of DRF were female (20.2% vs. 5.7%; p < 0.0001) and females were more likely to carry a pre-injury diagnosis of osteoporosis (9.3% vs. 0%; p < 0.0001). And 100% of the elderly patients received were treated with a volar plate. The overall early loss of reduction was 7.5%. The overall complication rate was 8.2%. No differences in early postoperative complications were identified between sexes or age groups. Neither female sex nor advanced age was found to have increased risk of postoperative complications or early loss of reduction. Similar postoperative radiographic parameter measurements were obtained across groups as well. Conclusions: Our results support the idea that operative treatment of unstable DRF in elderly patients and women is a reasonable treatment option without significant increases in early postoperative complications. Level of Evidence: Level III (Therapeutic III)
Investigating exchange, structural disorder, and restriction in gray matter via
water and metabolites diffusivity and kurtosis time-dependence
Authors: Mougel Eloïse , Valette Julien , Palombo Marco 
Published: March 2024

Abstract
Water diffusion-weighted MRI is a very powerful tool for probing tissue microstructure, but disentangling the contribution of compartment-specific structural disorder from cellular restriction and inter-compartment exchange remains an open challenge. In this work, we use diffusion-weighted MR spectroscopy (dMRS) of water and metabolite as a function of diffusion time in vivo in mouse gray matter to shed light on: i) which of these concomitant mechanisms (structural disorder, restriction, and exchange) dominates the MR measurements and ii) with which specific signature. We report the diffusion time-dependence of water with excellent SNR conditions as provided by dMRS, up to a very long diffusion time (500 ms). Water kurtosis decreases with increasing diffusion time, showing the concomitant influence of both structural disorder and exchange. However, despite the excellent experimental conditions, we were not able to clearly identify the nature of the structural disorder (i.e., 1D versus 2D/3D short-range disorder). Measurements of purely intracellular metabolites diffusion time-dependence (up to 500 ms) show opposite behavior to water, with metabolites kurtosis increasing as a function of diffusion time. We show that this is a signature of diffusion restricted in the intracellular space, from which cellular microstructural features such as soma’s and cell projections’ size can be estimated. Finally, by comparing water and metabolite diffusion time-dependencies, we attempt to disentangle the effect of intra/extracellular exchange and structural disorder of the extracellular space (both impacting water diffusion only). Our results suggest a relatively short intra/extracellular exchange time (~1-50 ms) and short-range disorder (still unclear if 1D or 2D/3D) most likely coming from the extracellular compartment. This work provides novel insights to help interpret water diffusion-time dependent measurements in terms of the underlying microstructure of gray matter and suggests that diffusion-time dependent measurements of intracellular metabolites may offer a new way to quantify microstructural restrictions in gray matter.
Stimulus on the Home Front: The State-Level Effects of WWII Spending
Authors: Brunet Gillian 
Published: March 2024

Abstract
I use newly-digitized contract data on U.S. war production spending over 1940-1945 to analyze the macroeconomic effects of U.S. military spending in World War II. I find personal income multipliers of 0.34 over two years and 0.49 over three years. Personal income multipliers may substantially understate GDP multipliers, perhaps by as much as 50%. Employment estimates imply costs per job-year over the same time horizons of $405,013 and $232,268 in 2015 dollars, suggesting job creation was limited. I also find evidence of negative scale effects: larger positive spending shocks are associated with systematically smaller multiplier estimates.
School Choice, Student Sorting, and Academic Performance
Authors: Munteanu Andrei 
Published: March 2024

Abstract
This study examines the impact of school choice on academic achievement. I use differences in the number of schools across similar Romanian towns, generating variation in school choice for local students, who compete for seats via test scores. I find that more school choice results in increased sorting of students by admission scores across different schools. Sorting widens achievement gaps between high- and low-admission score students. High-scorers having access to better teachers and peer effects are the primary factors explaining these widening gaps. Lastly, between-school competition via school choice does not increase average achievement levels.
Can Competitiveness Predict Education and Labor Market Outcomes? Evidence from Incentivized Choice and Survey Measures
Authors: Buser Thomas , Niederle Muriel , Oosterbeek Hessel 
Published: March 2024

Abstract
We assess the predictive power of two measures of competitiveness for education and labor market outcomes using a large, representative survey panel. The first is incentivized and is an online adaptation of the laboratory-based Niederle-Vesterlund measure. The second is an unincentivized survey question eliciting general competitiveness. Both measures are strong predictors of income, occupation, level of education and field of study. The predictive power of the new unincentivized measure is robust to controlling for other traits, including risk attitudes, confidence and the Big Five personality traits. For most outcomes, the predictive power of competitiveness exceeds that of the other traits.
Topological Signature of Stratospheric Poincaré-Gravity Waves

Published: March 2024

Abstract
The rotation of Earth breaks time-reversal and reflection symmetries in an opposite sense north and south of the equator, leading to a topological origin for certain atmospheric and oceanic equatorial waves. Away from the equator, the rotating shallow-water and stably stratified primitive equations exhibit Poincaré inertia–gravity waves that have nontrivial topology as evidenced by their strict superinertial time scale and a phase singularity in frequency–wavevector space. This nontrivial topology then predicts, via the principle of bulk-interface correspondence, the existence of two equatorial waves along the equatorial interface, the Kelvin and Yanai waves. To directly test the nontrivial topology of Poincaré-gravity waves in observations, we examine ERA5 data and study cross correlations between the wind velocity and geopotential height of the midlatitude stratosphere at the 50 hPa height. We find the predicted vortex and antivortex in the relative phase of the geopotential height and velocity at the high frequencies of the waves. By contrast, lower-frequency planetary waves are found to have trivial topology also as expected from theory. These results demonstrate a new way to understand stratospheric waves and provide a new qualitative tool to investigate waves in other components of the climate system.
Compatibility study of high density polyethylene grade 80 gas pipe with synthetic polyglycol-based brake oil
Authors: Alimi Latifa , Chaoui Kamel 
Published: March 2024

High Density Polyethylene (HDPE) is one attractive technical option for the transportation and distribution of natural gas and hydrocarbons given the advantages in long-term mechanical strength, lifespan, maintenance costs and resistance to chemical aging. This study investigates the compatibility of extruded pipe material from copolymerized HDPE-80 with DOT 3 brake fluid. Machined standard specimens from inner (IL) and outer (OL) pipe layers are aged in commercial synthetic polyglycol-based oil for 7 days at laboratory conditions. The percent mass changes are +2.2% and +1.9% respectively for IL and OL pipe surfaces. These results are in the same range of published sorption data for other oils and fuels. Stress-strain parameters (E, σ y, σ CD, σ f, ε y, Δ ε CD, ε f) and fracture work are established and thoroughly discussed for both pipe sides. For IL, the reduction of E, σ y and ε f are respectively 28.0%, 13.9% and 22.7%, while for OL they are 22.6%, 7.7% and 25.1%. Globally, it is concluded that strength properties degradation in DOT 3 oil is more important for IL compared to OL. There is an important loss of ductility for both pipe sides. Ageing caused IL crystallinity ( Xc) to increase while OL showed inverse results probably because of frozen anti-oxidants in the outer surface layers following water quenching during extrusion. Before and after ageing, the as-received OL is found to be more resilient to oxidation than corresponding IL, as higher OIT parameters are also shown in the case of crude oil compatibility investigations. DOT 3 brake oil seem to accelerate the degradation of HDPE-80 thermal stability with a higher intensity for IL.
Identifying characteristics of stroke patients benefiting from interprofessional collaboration
Authors: Ikeda Kohei , Sasada Satoshi 
Published: March 2024

Introduction: This study identifies the patient population that may benefit from interprofessional collaboration in the support of patients with cerebrovascular diseases. Method: This study involved 170 patients who received treatment in Japan’s recovery rehabilitation wards in December 2019–June 2020. Participants were categorized into three groups based on their functional independence measure (FIM) scores at admission, distinguishing between complete dependence, modified dependence, and independence groups. They were classified into the group with higher collaborative practice (HCP) and the group with lower collaborative practice (LCP) based on the median value of the therapist collaborative practice scale (TCPS). The primary outcomes measured were FIM efficiency and FIM effectiveness. The main effects and interactions of the level of independence with activities of daily living (ADL) and collaboration were examined using a two-way analysis of variance and Bonferroni multiple comparison tests. Results: The level of independence with ADL and collaboration had an interaction effect related to FIM effectiveness ( F(2, 164) = 3.191, p = 0.044). Within the independence group, HCP and LCP differed significantly ( F(1, 164) = 15.562, p < 0.001). Conclusion: Interprofessional collaboration may improve ADL in patients with high ADL independence at admission. Furthermore, the interprofessional collaboration quality impacted patients’ ADL improvement.
