Introduction
Road traffic accidents have become a global public health issue, especially in low- and middle-income countries (LMICs). According to the World Health Organization (WHO) Global Road Safety Report 2018, there are over 1.35 million deaths related to road traffic accidents (RTAs) annually. Although several primary studies have been conducted to determine the prevalence and associated factors of post-traumatic stress disorder (PTSD) among RTA survivors in sub-Saharan Africa (SSA), these studies have reported inconsistent findings. Therefore, this study aimed to determine the pooled prevalence and associated factors of PTSD among RTA survivors in SSA.

Methods
The studies were accessed through the Google Scholar, Scopus, PubMed, and Web of Science databases using search terms. Moreover, citation tracking was also performed. A random-effects DerSimonian-Laird model was used to compute the pooled prevalence of PTSD and determine associated factors among RTA survivors in SSA.

Results
A total of 17 primary studies with a sample size of 9,056 RTA survivors were included in the final meta-analysis. The pooled prevalence of PTSD among RTA survivors in SSA was 23.36% (95% CI: 18.36, 28.36); I2 = 96.73%; P < 0.001). Female gender [AOR = 2.33, 95% CI: 1.80, 3.01], depression symptoms [AOR = 2.96, 95% CI: 2.17, 4.03], duration since the accident (1-3 months) [AOR = 2.08, 95% CI: 1.23, 3.52], poor social support [AOR = 2.97, 95% CI: 1.09, 8.11], and substance use [AOR = 3.31, 95% CI: 1.68, 6.52] were significantly associated with PTSD.

Conclusions
The pooled prevalence of PTSD was low in SSA compared to studies that have been conducted outside the region. Female gender, depression symptoms, duration since the accident (1-3 months), poor social support, and substance use were the pooled independent predictors of PTSD among RTA survivors in SSA. Those RTA survivors with these identified risk factors would be screened and managed early for PTSD using pharmacological treatment and brief psychological intervention. Future researchers shall conduct further studies using different methods, including qualitative studies to identify additional predictors of PTSD among RTA survivors in SSA.
Pancreatic steatosis as a risk factor for pancreatic ductal adenocarcinoma: pathogenesis and clinical implications
Authors: Papalamprakopoulou Zoi , Dey Prasenjit , Frascati Rachel , Fountzilas Christos 
Published: February 2025

Abstract
Pancreatic steatosis is defined as the ectopic accumulation of fat in the pancreas. While historically considered a benign incidental imaging finding, it is now recognized as a significant, and potentially reversible risk factor for pancreatic ductal adenocarcinoma (PDAC) independently of obesity. Although its epidemiology is not well characterized, meta-analysis data suggest an approximately 30% prevalence, with individual studies reporting even higher rates among patients with obesity and/or metabolic syndrome. Concurrently, PDAC incidence is rising and is projected to soon become the second leading cause of cancer-related deaths. Given the critical importance of early PDAC detection and intervention for improving survival, it is particularly timely to explore the associations between pancreatic steatosis and PDAC. This review aims to provide a comprehensive overview of the pathogenesis and clinical associations between pancreatic steatosis and PDAC, as well as to discuss future perspectives within the context of current PDAC surveillance practices.

Authors: Khaira Hargun Kaur , Kochhar Sonia , Aneja Jitender , Verma Madhur , Rajendran Rajathi , Thind Anupinder 
Published: February 2025

Abstract

Objectives
This study aims to explore the relationship between chronotypes, sleep quality, and anxiety among medical undergraduates, providing valuable insights for academic institutions seeking to enhance student well-being.

Methods
A cross-sectional design was used, involving 200 medical undergraduates who were selected based on specific inclusion and exclusion criteria. Data collection included comprehensive clinical histories and the administration of three validated questionnaires: the Morningness-Eveningness Questionnaire Self-Assessment (MEQ-SA), the Pittsburgh Sleep Quality Index (PSQI), and the State-Trait Anxiety Inventory (STAI). Participants were recruited during class breaks, and informed consent was obtained prior to participation.

Results
The majority of participants (76.5 %; n=152) exhibited a neutral chronotype, with a mean MEQ score of 50.18 (±7.781). No significant correlations were found between MEQ scores and variables such as sex, BMI, or electronic media use. However, individuals classified as evening types reported higher anxiety levels, with mean STAI-S and STAI-T scores of 56.09 (±4.566) and 49.09 (±6.202), respectively (ANOVA, F=31.798, p=0.001; F=30.294, p=0.001). The mean global PSQI score was 6.00 (±2.553), with 56 % of participants reporting poor sleep quality. Evening chronotypes had significantly poorer sleep quality, as evidenced by higher PSQI scores (8.14±1.670) (ANOVA, F=43.663, p=0.001).

Conclusions
The findings underscore the need for academic institutions to reconsider the alignment of academic schedules with students’ chronotypes, potentially enhancing academic performance and reducing health risks. Despite these contributions, the study has limitations, including geographical and demographic constraints and reliance on self-reported data, suggesting the need for further research to provide more comprehensive insights.
Error analysis of virtual element method for the Poisson–Boltzmann equation
Authors: Huang Linghan , Shu Shi , Yang Ying 
Published: February 2025

Abstract
The Poisson–Boltzmann equation, which incorporates the source of the Dirac distribution, has been widely applied in predicting the electrostatic potential of biomolecular systems in solution. In this paper we discuss and analyse the virtual element method for the Poisson–Boltzmann equation on general polyhedral meshes. Nearly optimal error estimates, approaching the best possible accuracy, are achieved for the virtual element approximation in both the L
2-norm and H
1-norm, even when the solution of the entire domain has low regularity. The efficiency of the virtual element method and the validity of the proposed theoretical prediction are confirmed through numerical experiments conducted on various polyhedral meshes.
A Robin–Robin strongly coupled partitioned method for fluid–poroelastic structure interaction
Authors: Parrow Connor , Bukač Martina 
Published: February 2025

Abstract
This work focuses on the development of a novel, strongly-coupled, second-order partitioned method for fluid–poroelastic structure interaction. The flow is assumed to be viscous and incompressible, and the poroelastic material is described using the Biot model. To solve this problem, a numerical method is proposed, based on Robin interface conditions combined with the refactorization of the Cauchy’s one-legged ‘ϑ-like’ method. This approach allows the use of the mixed formulation for the Biot model. The proposed algorithm consists of solving a sequence of Backward Euler–Forward Euler steps. In the Backward Euler step, the fluid and poroelastic structure problems are solved iteratively until convergence. Then, the Forward Euler problems are solved using equivalent linear extrapolations. We prove that the iterative procedure in the Backward Euler step is convergent, and that the converged method is stable when ϑ ∈ [1/2, 1]. Numerical examples are used to explore convergence rates with varying parameters used in our scheme, and to compare our method to a monolithic method based on Nitsche’s coupling approach.

Published: February 2025

Abstract

Purpose
The aim of this research study is to assess the ability of quercetin to protect the heart from the negative consequences of tacrolimus-induced cardiotoxicity.

Methods
A total of 30 rats were divided into 5 groups. Tacrolimus was used to induce cardiotoxicity, whereas quercetin was employed as a protective agent.

Results
Tacrolimus administration significantly raised the levels of serum cardiac biomarkers (Lactate dehydrogenase, creatine kinase-myocardial band, and troponin-I) as well as inflammatory biomarkers (tumor necrosis alpha and interleukin 6). The administration of quercetin reduced raised levels of cardiac and inflammatory biomarkers significantly. In addition, treatment with tacrolimus resulted in higher malondialdehyde (MDA) (lipid peroxidation marker) levels and falling in the levels of reduced glutathione (GSH) as well as antioxidant enzymes such as superoxide dismutase (SOD), glutathione reductase (GR), and catalase (CAT). Quercetin treatment significantly reduced MDA levels and increased GSH and antioxidant enzyme (SOD, GR, and CAT) levels. Moreover, the tacrolimus-administered group exhibited histological changes in cardiac tissue cited as vacuole formation, large and uncondensed nucleus, and cardiomyocyte hypertrophy. The quercetin treatment reduced the inflammatory cell infiltration in cardiac tissue and thus reduced vacuole formation and hypertrophy.

Conclusions
The outcome showed quercetin’s cardioprotective potential against tacrolimus-administered cardiotoxicity. Consequently, it is concluded that quercetin may be used as add-on therapy with tacrolimus to reduce cardiac adverse effects.

Authors: Sakr Mohamed , Nemerofsky Sheri , Cano Nefertiti , Alapatt Leena , Anzalone Cassie , Nafday Suhas 
Published: February 2025

OBJECTIVE
Point-of-care ultrasound (POCUS) is a reliable tool and is slowly being incorporated into neonatal care. Central line (CL) placement is the most common procedure in the neonatal intensive care unit. Radiographs remain the current standard to confirm the location of the central line tip (CLT). Catheters often need adjustments with multiple x-rays. A quality improvement (QI) project was designed to use POCUS and increase the percentage of CLs needing only 1 x-ray to confirm CLT location by 25% in 1 year.

METHODS
CLs placed between July 2021 and February 2024 were included. There were 3 key drivers: POCUS training, promoting POCUS acceptance, and standardizing the scanning process. The primary outcome was the percentage of CLs placed with POCUS that required only 1 x-ray to confirm placement. The secondary outcome was the number of inadvertently placed arterial peripherally inserted central catheters (PICCs). Process measures were the percentage of providers competent to use POCUS and the percentage of CLs inserted and checked with POCUS. Statistical process control charts were used for analysis.

RESULTS
Targeted interventions increased the percentage of CLs that needed only 1 x-ray from 35% to 57%. Forty-eight percent of providers were competent, and 47% of CLs were assessed by POCUS. Five PICCs were inadvertently inserted into an artery during the baseline vs zero after the interventions.

CONCLUSION
QI methodology and targeted interventions were associated with a reduction of x-rays in neonates requiring CL placement to confirm position and a reduction in the inadvertent arterial insertion of PICCs.

Published: February 2025

OBJECTIVE
Increasing state-level cannabis legalization in the United States aims to reduce risks to consumers through regulation but may also lead to more unlicensed retailers and youth access. This study examines how age verification and business practices (eg, pricing, signage, and youth-appealing products) differ by licensing status.

METHODS
The Cannabis Access and Safety in New York (CASNY) secret shopper study observed 37 dispensaries and smoke shops (5 licensed medical, 7 licensed recreational, 10 unlicensed dispensaries, and 15 smoke shops), randomly selected from 840 outlets across New York City (NYC) in November to December 2023 to audit age verification and other business practices.

RESULTS
Licensed retailers were significantly more likely to require age verification before store entry (100% vs 10%, P &lt; .01) and purchase (100% vs 48%, P = .01). Unlicensed retailers displayed more cartoon signage (57% vs 0%) and sold youth-appealing products like energy drinks (48% vs 0%), soda (57% vs 0%), and candy (53% vs 0%). Both types of retailers were often near schools (75% and 76%) and offered delivery (58% and 36%) but rarely displayed health warnings (8% and 10%).

CONCLUSION
In NYC, unlicensed retailers outnumber licensed ones and often engage in practices increasing youth access to cannabis. They infrequently verify age, sell cheaper products, and use youth-friendly marketing. Licensed retailers follow age verification laws but are also often near schools and inconsistent with certificates of analysis provision. Further research is needed on policy impacts on youth cannabis use in deregulated markets.

Abstract
Biomaterials play a crucial role in advancing biosensor technologies for medical, environmental, and food safety applications. This study investigates natural biomaterials, such as food-derived chromophores, cellulose, and peptides, for high-performance biosensors and bioelectronic devices. Chromophores, namely grape anthocyanins, are potential candidates for the development of artificial retinal devices showing light-responsivity at 435 nm, close to the human blue cone photoreceptors (420 nm), and transient photo-current signals of 15 nA/mm2 (20 ms, blue-light pulse). Realized cellulose-silk fibroin (SF:CNCs)-based biodegradable substrates are suitable for flexible and sustainable optoelectronic devices, showing transmittance over 40% (400 and 800 nm) and good stress at break (60 MPa at 5%). Peptides, derived from enzymes, are used as biorecognition elements in EGOFETs for detecting polystyrene nanoplastics with a sensitivity of 60.3%/(mg/ml). Through the use of chromophores, SF:CNCs-based substrates, and peptide, new biosensors are developed displaying promising applications in biomedicine, green electronics, and environmental pollution-monitoring.

The facilitators and barriers encountered by South African parents regarding Sensory Integration occupational therapy
Authors: Smit Jacintha , De Jongh Jo-Celene , Cook Ray Anne 
Published: February 2025

Introduction: Differences in parent perceptions regarding occupational therapy using a sensory integration approach to treatment have been noted. The various factors that may influence these perceptions, and how the perceptions may ultimately influence the outcome of the intervention for the child and family were questioned. A phenomenological study revealed a progression that all parents perceived and experienced as the "before", "input" and "after" phases of when their child received occupational therapy/sensory integration (OT/SI). This article focuses specifically on the "input" phase of OT/SI intervention.
Method: Participants in this study were nine parents of children with difficulties processing and integrating sensory information, who live in the Western Cape, South Africa. Using a qualitative, phenomenological approach, data were collected during face-to-face interviews, participant observation and researcher's field notes.Â
Findings: The main theme related to this phase of analysis was "Just suddenly everything made so much sense". For most participants, this phase brought to light a better understanding of sensory integration disorder (SID), also known as Sensory Processing Disorder (SPD) and OT/SI. Data analysis identified two subthemes that catalysed expansion in most participants' understanding, which were the role of the occupational therapist, and the OT/SI intervention process. Within these subthemes, the facilitating factors and barriers of OT/SI intervention emerged.
Conclusion: Insight gained from the participants' recommendations and interpretation of findings allowed recommendations to be made within the OT/SI intervention received, in an attempt to overcome the barriers and promote the facilitators that will make a difference to OT/SI in South Africa.Â
Key words:
Sensory integration; sensory integration disorder (SID); sensory processing disorder (SPD); parent(s) perceptions; facilitators; barriers.
Rereading a theory: Does the income level of countries affect the consumer behavior?
Authors: Greene William H , Hatamerad Saman , Oskoui Haleh Raiszadeh , Asgharpur Hossian , Adrangi Bahram 
Published: February 2025

This study examines how income levels influence consumer behavior, particularly through the lens of Duesenberry’s relative income and ratchet effect hypotheses. Duesenberry's "ratchet effect" refers to the tendency for individuals to maintain their consumption levels at a higher level once they have reached a certain standard of living, even when their income falls, meaning they are less likely to cut back on spending significantly during economic downturns, similar to how a ratchet only allows movement in one direction; once consumption increases, it is difficult to reverse it downwards easily. The ratchet effect suggests that consumers are resistant to reducing their consumption levels despite decreases in income, as past consumption serves as a psychological baseline. We analyze these hypotheses across two distinct groups: middle-income countries (Brazil, Senegal, Kenya, Jordan) and high-income countries (Japan, Germany, Sweden, Belgium). Using time series data from 1970 to 2020, we employ an Autoregressive Distributed Lag (ARDL) model along with panel data regression to analyze 20 middle-income and 20 high-income countries from 1980 to 2018. Our findings confirm the ratchet effect in middle-income countries, where consumption patterns are strongly influenced by prior income levels, suggesting a persistent upward consumption bias even during economic downturns. However, in high-income countries, the ratchet effect exhibits inconsistent applicability, potentially due to higher income stability, stronger safety nets, and differing consumer priorities. These discrepancies highlight the varied behavioral responses to economic fluctuations based on income levels and societal norms.

Published: February 2025

The COVID-19 pandemic has resulted in the emergence of a livestream purchasing site that facilitates instantaneous purchases. The purpose of this study is to analyze the key determinants that contribute to the impulsive purchasing behavior of cosmetic products on live shopping platforms. There are four variables namely website quality, sales promotion, customer trust and financial availability are examined. This study used a quantitative research design to determine the relationship between the identified variables. Data collected from 200 respondents was analyzed using descriptive statistics and inferential analysis to establish the correlation. The research findings validate that the quality of a website, sales promotion, customer trust and financial availability exert a substantial impact on customers' impulsive purchasing behavior. The practical implications of the study offer valuable insights into the development of effective strategies for cosmetic businesses to enhance impulse buying behavior among customers on live commerce platforms.
(Kontr-)rewolucja oświatowa
Authors: Śliwerski Bogusław 
Published: February 2025

Planowanie oświatowe w aspekcie prognoz rozwoju kraju ma u nas charakter stricte ideologiczny, a więc adaptacyjny, czyli taki sam, z jakim mieliśmy do czynienia w okresie PRL. Dominuje tu normatywna funkcja założeń i zasad polityki oświatowej, koncentrująca uwagę władz na określaniu celów i treści kształcenia i wychowania z uwzględnieniem stosunku szkolnictwa do spraw nauczania religii. [...] Po trzydziestu latach transformacji mamy w polskiej polityce oświatowej naprzemienność normatywnych imperatywów władzy politycznej w procesie wychowawczym szkół bez jakiegokolwiek odwołania do Konstytucji III RP [...]. Nie ma zatem w polityce oświatowej ani planowania oświatowego, które musiałoby odbywać się na podstawie naukowych badań i analiz kluczowych dla edukacji czynników, ani prognozowania oświatowego mającego na celu przewidywanie przyszłych zjawisk na podstawie także naukowych danych, gdyż żaden z ministrów nie wie, jak długo będzie mógł realizować własny (w sensie własnego zaplecza partyjnego) projekt oświatowy.
Ze Wstępu
Autor od wielu lat diagnozuje brak uspołecznienia szkół i stawia tezę, że ostatnio przeprowadzona reforma ma charakter radykalnej zmiany, której celem jest przywrócenie praktykowanych wcześniej rozwiązań, ale również stanowi ona w sferze filozoficzno-ideologicznej zwrot w kierunku konserwatyzmu. Rekonstruuje przebieg zdarzeń prowadzących do tej „kontrrewolucji” oraz dowodzi, że jest to konsekwencja sposobu prowadzenia od trzydziestu lat polityki oświatowej.
