AbstractMovement disorders after dengue virus (DENV) infection have been increasingly recognized. We aimed to synthesize the clinical and paraclinical characteristics, treatment responses, and outcomes of these neurologic complications. We systematically reviewed PubMed, Embase, Scopus, and LILACS databases up to September 2023 following a published protocol. We identified 73 cases of DENV‐induced movement disorders. Cerebellar ataxia was the most common, followed by parkinsonism, opsoclonus–myoclonus–ataxia syndrome, and dystonia. Movement disorders typically developed within 14 days of DENV infection and were associated with a range of neurological symptoms, including cognitive impairment and psychiatric disturbances. Neuroimaging studies frequently showed abnormalities in the basal ganglia and brainstem. Treatment varied depending on the specific movement disorder and included corticosteroids, intravenous immunoglobulin, and symptomatic medications. Whereas a handful of cases met the criteria for acute encephalitis, many lacked sufficient data to establish a definitive diagnosis. Para‐infectious and postinfectious immune‐mediated movement disorders were also reported. A rare case of chronic progressive panencephalitis due to DENV infection highlights the potential for long‐term neurological consequences. Other DENV‐related complications, such as stroke, pituitary apoplexy, subacute thyroiditis, and metabolic disturbances, can also cause movement disorders. We emphasize the importance of recognizing the diverse neurological manifestations of DENV infection and the need for further research to improve our understanding of the underlying mechanisms and optimize treatment strategies. We propose a more rigorous approach to determining the causality between infection and movement disorder, demanding stronger evidence beyond mere association and advocating for targeted research to fill the existing knowledge gaps. © 2025 International Parkinson and Movement Disorder Society.

Metabolic disruption by mycotoxins: focus on metabolic endpoints steatosis, adipogenesis and glucose metabolism in vivo and in vitro
Authors: Heikkinen Tia , Küblbeck Jenni , Rysä Jaana 
Published: February 2025

Abstract
Metabolic disruption encompasses the processes leading to adverse effects to major metabolic organs, such as liver and pancreas after exposure to e.g., environmental chemicals. As some mycotoxins act as endocrine disruptors, their structural similarity may lead to effects in lipid and glucose metabolism as well. Via systematic literature search, we mapped the potential of mycotoxins to cause metabolic disruption. Our systematic data search involved mycotoxin keywords combined with metabolic disruption keywords. The retrieved 31 studies revealed 24 in vivo studies, and 18 in vitro studies in total of 13 different mycotoxins. Most studied parameters were triglycerides from blood or liver, followed by total cholesterol and glucose or insulin levels. In vitro studies most often aimed to reveal mechanisms of metabolic disruption, but common metabolic parameters (lipid or cholesterol accumulation). In general, mycotoxin exposure showed a trend towards positive metabolic effects, such as reduction of blood triglycerides levels. Emodin was the most studied mycotoxin. Other mycotoxins were studied in one to three studies. Positive effects were also identified for equisetin, fumonisin B1, fumigaclavine C and ergostatrien-3-B-ol. Adverse effects (e.g. increased lipid deposition to liver) were identified for aflatoxin B1, ochratoxin A, deoxynivalenol, citreoviridin, T-2 toxin and paxilline. As demonstrated by the evaluated in vivo and in vitro studies, mycotoxins seem to have more positive than negative effects on metabolism. However, based on the available data, a general conclusion on the role of mycotoxins as a group cannot be made.

Additionally, an improved analytic microdosimetry model is proposed. The original analytic model of Xapsos is refined and model parameters are updated based on Geant4-DNA physics model. Direct proton energy deposition is described by an alternative energy-loss straggling distribution and the contribution of secondary electrons is calculated using the dielectric formulation of the relativistic Born approximation. MCTS simulations of proton

It is envisioned that the proposed model might be used as an alternative to CPU-intensive MCTS simulations and advance practical microdosimetry and quality factor calculations in medical, accelerator, and space radiation applications.
Analysis of the potential for analog and digital signal transmission via axial and radial rolling element bearings as signal transmission elements for rotating shafts
Authors: Besier Jasmin , Becker-Dombrowsky Florian Michael , Hausmann Maximilian , Kirchner Eckhard 
Published: February 2025

Abstract
In the context of advancing digitalization, the focus is on data acquisition using suitable sensors. Therefore, data acquisition and the required sensor technology should be located within the system to measure as close to the process as possible. With rotating systems in mechanical engineering, the integration of sensors on rotating elements poses a challenge, because the recorded data must be transferred from the rotating element to the evaluation unit. One option for this is electrical contacts like slip rings. However, these have the disadvantage that additional elements and installation space are required in the system.
In this article, the technical possibilities of using conventional rolling bearings as signal transmission elements are investigated. For this purpose, analog and digital signals are transmitted via radial and axial rolling bearings under different operating conditions. The transmission quality is quantitatively analyzed. Analog voltage signals and digital signals modulated in various ways are used as test signals.
It can be seen that the capacitive behavior of the rolling bearings causes a damping signal transmission behavior for analog signals. Axial and radial rolling bearings differ in their resulting damping of the transmitted electrical signals. The carrier frequency of the signals, the oil temperature and the bearing loads have a significant influence on the damping behavior.
Robust signal transmission is observed with digital signals. Frequency shift keying and phase shift keying modulations exhibit the lowest transmission errors. Amplitude shift keying can only be used with restrictions due to the pronounced damping behavior of the rolling bearings.
Overall, there is a pronounced potential for the transmission of analog and, above all, digital sensor signals via rolling bearings as a transmission element between rotating and stationary systems. In addition to the potential, the work also shows new research directions for further investigations.
Representations of the Symmetric Group are Decomposable in Polynomial Time
Authors: Olver Sheehan 
Published: February 2025

Abstract
We introduce an algorithm to decompose matrix representations of the symmetric group over the reals into irreducible representations, which as a by-product also computes the multiplicities of the irreducible representations. The algorithm applied to a d-dimensional representation of

$$S_n$$

is shown to have a complexity of

$${\mathcal {O}}(n^2 d^3)$$

operations to fully decompose representations with non-trivial multiplicities. These complexity bounds are pessimistic and in a practical implementation using floating point arithmetic and exploiting sparsity we observe better complexity. We demonstrate this algorithm on the problem of computing multiplicities of two tensor products of irreducible representations (the Kronecker coefficients problem) as well as higher order tensor products. For hook and hook-like irreducible representations the algorithm has polynomial complexity as n increases. We also demonstrate an application to constructing a basis of homogeneous polynomials so that applying a permutation of variables induces an irreducible representation.

Published: February 2025

Abstract
Generalised anxiety disorder (GAD) is associated with cognitive and physiological symptoms including uncontrollable worry, inhibitory control deficits, and low heart rate variability (HRV). Literature linking HRV and inhibition in GAD is predominantly correlational. The present experiment investigated whether HRV has a causal role in maintaining inhibitory control. Participants (N = 135, 111 female) aged 18–37 reporting high levels of symptoms associated with GAD (GAD-7 scores ≥ 10; Penn State Worry Questionnaire scores ≥ 56) were assigned to an experimental or active control condition and completed baseline measures of HRV, respiration rate, and inhibitory control. The experimental condition completed resonance frequency breathing (RFB) training, and the control condition practiced breathing at their mean breathing rate before repeating the inhibitory control assessment. Participants also completed the breathing training before a behavioural worry task. The experimental condition was predicted to show increased HRV, alongside improved inhibitory control and better ability to stop worrying as compared to the control condition. HRV increased during the experimental condition, as compared to the control condition. However, there were no significant effects of RFB on inhibitory control or worry, or on HRV during the inhibitory control tasks. In conclusion, RFB can increase HRV in high GAD scorers, but further research is required to determine whether there is a relationship between increased HRV and symptoms of GAD in a single session experiment.

Abstract
Understanding the biogeochemical cycling of phosphorus (P), particularly organic P (OP) in soils, under varying land use and soil development processes is essential for optimizing P usage under P fertilizer crisis. However, the complexity of OP impedes the mechanistic understanding. Therefore, by using well-documented organic carbon (OC) and total nitrogen (TN) cycling, we studied their stoichiometric correlation with P in soil fractions to indicate soil organic matter (SOM) and P turnover under two land uses (Cropland VS. Grassland) in Germany. Our results showed that grassland soils on the hillslope have higher OC and TN stocks than cropland soils. Total P (TP) stocks were unaffected by land use. However, grassland topsoil exhibited higher OP stocks and OP/TP proportions than cropland, with a constant IP stock throughout the soil profile, as this was determined by soil development processes in the subsoil. This proves that the flood plain soils are decoupled from hillslope soils due to different soil development processes. The stoichiometric assessment revealed a higher enrichment of OP in fine fractions of grassland soils, indicating stronger resistance to P loss by soil degradation. Mechanistic insights from OC:OP ratio of fine fractions indicate two potential OP cycling pathways: a ratio similar to microbial biomass C:P ratio suggesting a greater OP stabilization within microbial biomass/necromass; whereas a narrower ratio indicating more OP associated directly with mineral surfaces. This study illuminates the complex interplay between land use and soil development processes on OC, TN and P cycling, emphasizing the potential of stoichiometric assessment in soil fractions to understand OP biogeochemical cycling.
One Head is Better than Two: A Polynomial Restriction for Propositional Definite Horn Forgetting
Authors: Liberatore Paolo 
Published: February 2025

Abstract
Logical forgetting is NP-complete as a decision problem even in the simple case of propositional Horn formulae, and may exponentially increase their size. A way to forget is to replace each variable to forget with the body of each clause whose head is the variable. It takes polynomial time in the single-head case: each variable is the head of at most a clause. Some formulae are not single-head but can be made so to simplify forgetting. They are called single-head equivalent. The first contribution of this article is the study of a semantical characterization of single-head equivalence. Two necessary conditions are given. They are sufficient when the formula is interequivalent, that is, the formula makes two sets of variables equivalent only if they are also equivalent to their intersection. All acyclic formulae are interequivalent. The second contribution of this article is an incomplete algorithm for turning a formula single-head. In case of success, forgetting becomes possible in polynomial time and produces a polynomial-size formula, none of which is otherwise guaranteed. The algorithm is complete on interequivalent formulae.

Published: February 2025

Abstract
Social support plays a key role in behavioral changes, especially in Appalachian populations. We examined the mediating effect of social support in behavioral changes and corresponding weight loss outcomes among Appalachian adults. Data were from a group-randomized trial that compared a 12-month faith-based weight loss intervention to an active control group among overweight Appalachian adults in churches. Participants from the weight loss intervention who completed the 12-month assessment were the focus of this analysis. Baseline and 12-month data on weight, social support for eating habits (SSEH) and physical activity (SSPA) from family, friends, and church family, physical activity, and dietary intake were collected. Logistic and linear regression models evaluated mediating effects of SSEH and SSPA on the association between intervention attendance and behavioral changes and corresponding weight loss outcomes. Most participants (n = 243) were female (76.2%), white (97.5%), and married or living with a partner (81.2%). After the 12-month intervention, participants lost weight (1.1 ± 0.3 kg), increased fruit and vegetable intake (0.4 ± 0.1servings/day), reduced caloric intake (322.9 ± 42.2 kcal/day), improved SSEH from family, and increased SSPA from the church family (all P < 0.05). Increased SSEH from family mediated 62% of the association between intervention attendance and fruit and vegetable servings per day. Each 100 kcal decrease in caloric intake was associated with decreased weight and BMI at 12-months (0.2 ± 0.1 kg, P = 0.003; 0.1 ± 0.02 kg/m2, P = 0.002). Our study demonstrated the mediation effect of social support for healthy eating on the association between intervention attendance and fruit and vegetable intake, which underscored the critical role of social support and calorie intake among Appalachian populations in losing weight. The study was pre-registered at clinicaltrials.gov (#NCT02121691).
Exploring E-Cigarette Use Among Indonesian Youth: Prevalence, Determinants and Policy Implications

Published: February 2025

Abstract
The growing popularity of electronic cigarettes (e-cigarettes) among Indonesian youth presents a new public health challenge in a country with one of the highest tobacco burdens globally. While tobacco control regulations have been implemented, e-cigarettes remain largely unregulated, raising concerns about their health impacts and youth appeal. This study explores the prevalence, determinants and perceptions of e-cigarette use among high school and university students in Indonesia, providing critical insights to inform effective policymaking. A cross-sectional online-based survey was conducted in 2019 among 158 students aged 15–30 years across 17 provinces in Indonesia. Data on tobacco use behaviours, socioeconomic background, social influences and health perceptions were collected. Descriptive and inferential statistical analyses identified key determinants of e-cigarette use. Among the participants, 36.2% reported ever smoking, and 65.2% of these had tried e-cigarettes. Key determinants of e-cigarette use included male gender, urban residency, peer smoking and social acceptance of smoking (all p < 0.05). Notably, participants commonly perceived e-cigarettes as less harmful than combustible cigarettes and helpful for smoking cessation, despite conflicting scientific evidence. Overall, e-cigarette use is prevalent among Indonesian youth, driven by social and environmental factors, as well as misconceptions about safety. Strengthened regulations and targeted public health campaigns are essential to mitigate the health risks posed by e-cigarettes and enhance tobacco control efforts.
Sustaining Hope Within Entangled Accompaniments: Toward an Otherwise Clinical Ethnography and Critical Social Medicine
Authors: Hing Matthew , Keshavjee Salmaan 
Published: February 2025

Abstract
The series of papers in this special issue, “Ethnography of and in Clinical Formation: Poetics and Politics of Dual Subjectivity,” touch on several themes that are at the core of social medicine: the web of social structures and power relations that organize the risk and prematurity of disease and death, who gets care when and where, and what that care looks like and does within situated social worlds. As Levenson and Samra (this issue) describe in their contribution, social medicine turns on extending the field of medical action “beyond the clinical encounter” in order to visibilize how such encounters are “organized by wider regimes of governance and expertise, and broader geographies of care, abandonment and violence.” Writing from the “fractured habitus” as reported by Schlesinger (Doing and seeing: Cultivating a “fractured habitus” through reflexive clinician ethnography, Somatosphere, 2021) of clinician-ethnographers, the authors here witness and interrogate the nascent possibilities for more liberatory and autonomous forms of care within these otherwise determining regimes. They also expose the limits of traditional clinical ethnographic positioning through authors’ diverse participations within spaces of organized violence – indicating the need for a “new conceit” (Aboiil, this issue) of the clinical ethnographer/social medicine practitioner who is open to sitting in the trouble of a “complicity consciousness” (Sufrin, this issue) and the expanded fields of theorizing, action, and accompaniment that it makes possible.
Consumer confidence as a mediator between dividend announcements and stock returns
Authors: Hasan Fakhrul , Al-Najjar Basil 
Published: February 2025

Abstract
In this study, we examine the potential influence of consumer confidence on the association between announcing dividend payments and stock returns. We used FTSE 350 spanning the period from 1990 to 2021, using the UK consumer confidence index as a proxy for investor sentiment. The primary empirical test focused on cumulative abnormal returns [− 1, + 1], supplemented by a robustness test spanning [− 10, + 10]. Additionally, a generalized method of moments (GMM) estimation was conducted using CAR [− 1, + 1]. Our analysis revealed: under positive consumer confidence, firms announcing dividend increases experienced a positive market response, while under negative consumer confidence, firms announcing dividend decreases elicited a negative market reaction. This study contributes valuable insights to the discourse on investor sentiment and its impact on stock market dynamics.
