Authors: Härkönen Henna , Myllykangas Kirsi , Kärppä Mikko , Rasmus Kirsi Maaria , Gomes Julius Francis , Immonen Milla , Hyvämäki Piia , Jansson Miia
Published: December 2024

BACKGROUND

Cerebrovascular diseases (CVDs) are a major and potentially increasing burden to public health. Digital health interventions (DHIs) could support access to and provision of high-quality health care (eg, outcomes, safety, and satisfaction), but the design and development of digital solutions and technologies lack the assessment of user needs. Research is needed to identify opportunities to address health system challenges and improve CVD care with primary users of services as the key informants of everyday requirements.

OBJECTIVE

This study aims to identify opportunities for DHIs from clients’ and health care professionals’ perspectives to address health system challenges and improve CVD care.

METHODS

This study used a qualitative, descriptive approach. Semistructured, in-person interviews were conducted with 22 clients and 26 health care professionals in a single tertiary-level hospital in Finland between August 2021 and March 2022. The data were analyzed using a deductive and inductive content analysis.

RESULTS

Identified opportunities for DHIs in CVD care were organized according to clients, health care professionals, and data services and classified into 14 main categories and 27 generic categories, with 126 subcategories of requirements. DHIs for clients could support the long-term management of health and life changes brought on by CVD. They could provide access to personal health data and offer health information, support, and communication possibilities for clients and their caregivers. Health care professionals would benefit from access to relevant patient data, along with systems and tools that support competence and decision-making. Intersectoral and professional collaboration could be promoted with digital platforms and care pathways. DHIs for data services could enhance care planning and coordination with novel predictive data and interoperable systems for data exchange.

CONCLUSIONS

The combined study of client and health care professional perspectives identified several opportunities and requirements for DHIs that related to the information, availability, quality, acceptability, utilization, efficiency, and accountability challenges of health systems. These findings provide valuable social insights into digital transformation and the emerging design, development, and use of user-centered technologies and applications to address challenges and improve CVD care and health care.
Coefficient of Variation to Assess the Reproducibility of Meal-Induced Glycemic Responses (Preprint)
Authors: Lubasinski Nicole , Thabit Hood , Nutter Paul W. , Petrescu David , Haper Simon
Published: December 2024

BACKGROUND

Managing Type 1 Diabetes (T1D) requires maintaining target blood glucose levels through precise diet and insulin dosing. Predicting postprandial glycemic responses (PPGRs) based solely on carbohydrate content is limited by factors like meal composition, individual physiology, and lifestyle. Continuous glucose monitors (CGMs) provide insights into these responses, revealing significant individual variability.

OBJECTIVE

The statistical clustering method propsed here balances the number of clusters formed and the glycemic variability of the PPGRs within each cluster to offer a clustering technique on which treatment decisions could be based.

METHODS

Blood glucose (BG) data from the OhioT1DM dataset were to assess clustering of PPGR based on the CV of glucose. Clustering was performed using statistical clustering, with each PPGR isolated into 48 data points per event. A CV threshold of <36% was used to define clinically similar clusters. This aimed to cluster PPGRs with minimal glycemic variability. The approach aims to enhance precision in analyzing postprandial glycemic dynamics, assessing cluster cohesion via standard deviation and CV within meal categories.

RESULTS

The analysis revealed a reproducible set of PPGR-clusters specific to meal types and individuals (2.4±1.8 for breakfast, 2.7±0.9 for lunch, 3.1±1.0 for dinner), with the number of clusters varying across participants and meals in the dataset. Carbohydrate intake alone did not affect cluster formation, suggesting a complex relationship between meal composition and PPGR variability. However, certain individuals showed significant associations between carbohydrate intake and cluster formation for specific meals.

CONCLUSIONS

The meal-based glycemic clustering algorithm provides a promising framework for predicting PPGRs in people living with T1D (PwT1D), independent of carbohydrate intake. It emphasizes the need for personalized prediction models to optimize TIR and enhance diabetes management. Efforts to refine treatment strategies are crucial in reducing T1D-related complications.
Coexistence of accompanying autoimmune diseases in adolescents with autoimmune thyroiditis
Authors: Pankiv V.I.
Published: November 2024

Background. Autoimmune thyroiditis (AIT) is the most common cause of goiter and acquired hypothyroi­dism in children and adolescents living in iodine-sufficient regions. Most studies, which investigated the coexistence of AIT and other autoimmune diseases, were conducted in the adult patient population, and examined the prevalence of AIT in nonthyroid autoimmune diseases. The purpose of the study was to investigate the coexistence of other accompanying autoimmune diseases in adolescents aged 14–18 years who were diagnosed and followed up at the Ukrainian Scientific and Practical Centre of Endocrine Surgery, Transplantation of Endocrine Organs and Tissues of the Ministry of Health of Ukraine. Materials and methods. A total of 110 patients aged 14–18 years diagnosed with AIT were examined. Their age at admission, sex, family history, complaints at admission, comorbidities, physical examination and laboratory fin­dings, clinical follow-up information were retrospectively reviewed. Results. Of the 110 patients, 74.6 % were female and 25.4 % were male, with a mean age of 15.9 ± 2.1 years. A total of 9 (8.2 %) of the patients had overt hypothyroidism, 29 (26.4 %) had subclinical hypothyroidism, and 72 (65.4 %) had euthyroidism. High level of thyroid peroxidase antibo­dies was detected in 108 (98.2 %) patients, and 81 (73.6 %) had high thyroglobulin antibody levels (Tg-Ab). There was a family history of autoimmune disease in 43.6 % of cases. Autoimmune diseases accompanying AIT were present in 29 (26.4 %) of patients. The most common of them were type 1 diabetes (17.3 %), celiac disease (2.7 %), skin diseases (8.2 %), and rheumatologic diseases (2.7 %). The mean age of AIT patients with and without concomitant autoimmune disease was similar. In both groups, female sex was dominant. The rate of subclinical hypothyroidism was statistically significantly elevated in the group without accompanying autoimmune disease (p < 0.001). A statistically significant relationship was found between elevated Tg-Ab and concomitant autoimmune disease. The prevalence of accompanying autoimmune disease was increased 2.34 times in patients with elevated Tg-Ab levels. Conclusions. Autoimmune diseases, especially T1DM and skin diseases, are associated with AIT. There is an increased risk of autoimmune disease in AIT that affects both sexes. Regular follow-up of AIT patients with elevated Tg-Ab levels for autoimmune disease development is important in terms of earlier diagnosis of diseases.

Published: December 2024

Chronic kidney failure is a disease that affects the world's population and an alternative solution is hemodialysis. Hemodialysis is the process of cleaning the blood from urea and creatinine through a semi-permeable membrane in the form of a hollow fiber membrane (HFM) with the following advantages: flexible and low energy requirements. The weaknesses of commercial hemodialysis membranes are that they are hydrophobic, chemical resistant, and low biocompatibility. This research uses a membrane of polysulfone combined with eugenol and polyethylene glycol (PEG) or polyethylene glycol diglycidyl ether (PEGDE). Eugenol has allyl, hydroxy, and methoxy groups which are derived from polyeugenol via allyl groups and from polyeugenol to polyeugenoxy acetic acid via hydroxyl groups. The resulting molecularly imprinted membrane (MIM) in the form of hollow fiber has better porosity, absorption, flux values and is highly selective in transport, with the order of selectivity, namely urea > creatinine > vitamin B12.

Published: December 2024

A novel and simple method was used to synthesize antimicrobial and antioxidant porous (N-tert-butylacrylamide-co-N-vinylpyrrolidone) zinc oxide hydrogel via free radical copolymerization. The hydrogel was characterized by NMR, XRD, and SEM. Thermodynamic properties of the hydrogel were described quantitatively by the Flory-Rehner method. The results indicate that the synthesized hydrogel exhibits strong antioxidant activity, making it a potential candidate for use in preventing degenerative diseases. The antimicrobial tests showed that the hydrogel could inhibit the growth of Gram-positive and Gram-negative bacteria, as well as some pathogenic bacteria and fungi. The inhibition zones ranged from 10 to 15 mm for bacteria and from 5.2 to 9.1 mm for fungi. The reactivity ratio r1 × r2 equal to 1 confirmed ideal copolymerization showed the composition of the copolymer and the comonomer feed are same. The hydrogel's structure and reactivity are significant for constructing effective delivery systems for specific applications. Optimizing the monomer proportion could enhance hydrogel efficiency and release behavior. The hydrogel's water solubility, non-toxicity, and antioxidant properties suggest it could be safe and effective throughout the drug delivery process, contributing both passive and reactive targeting functions.

Published: December 2024

Centella asiatica is a medicinal plant widely used as a traditional medicine due to several biological activities, such as antioxidants in Indonesia. This study aims to identify the active antioxidant compounds of C. asiatica leaves extract using a liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS)-based metabolomics approach. Extracts were prepared using different concentrations of ethanol p.a., i.e. 70% ethanol, 50% ethanol, 30% ethanol, and water. Antioxidant activity was tested using the 2,2-diphenyl-1-picrylhydrazyl method. The results showed the highest antioxidant activity was C. asiatica extracted by 70% ethanol with IC50 of 72.48 ± 2.42 µg/mL. The positive control was ascorbic acid, having an IC50 value of 3.38 ± 0.04 µg/mL. Ascorbic acid and 70% ethanol extract have strong antioxidant activity. Metabolite profiling using LC-MS/MS could identify 35 metabolites consisting of flavonoids, fatty acids, phenolics, terpenes, and several other groups of compounds. Orthogonal partial least squares-discriminant analysis classified the metabolites into active (ethanol 70% and ethanol 50%) and inactive (ethanol p.a., ethanol 30%, and water) antioxidants. Five metabolites have potential as antioxidants, namely 4,5-dicaffeoylquinic acid (11), kaempferol (13), and three unknown compounds.

The rGO/CeO2/epoxy composite has been successfully prepared as radar absorbing material (RAM) for the X-band (8–12 GHz) region. The reduced graphene oxide (rGO) originated from pencil graphite oxide (GiO) was synthesized through the modified Hummer method. The synthesis of rGO/CeO2/epoxy was conducted by immobilization of cerium(IV) oxide into rGO (rGO/CeO2) via hydrothermal method and followed by composited the rGO/CeO2 with epoxy resin matrix. Morphological analysis by SEM-EDX indicates that the rGO/CeO2 structure appears to be a tangled layer of edges randomly aggregated, and CeO2 is uniformly anchored on the rGO surface. From the diffractogram result of the XRD instrument, rGO exhibits changes in crystallinity, indicating a transformation of the interlayer structure from multilayer GiO to a single layer of rGO. The presence of Ce–O was indicated at wavenumber 553 cm−1 of rGO/CeO2 by FTIR. The microwave absorbing performance of rGO/CeO2/epoxy conducted by vector network analyzer (VNA) showed that the RL value of the composite was −3.22 dB (47% of electromagnetic wave absorption) at a frequency of 9.25 GHz at the thickness of 1 mm composite. The composite has the promising prospect of being developed as a captivating candidate for the new type of microwave absorptive materials.

Authors: Souhuat Alexander , Aritonang Henry Fonda , Koleangan Harry Steven Julius
Published: December 2024

According to the World Bank study, approximately 17–20% of water contamination is attributed to the textile industry. The quantity of waste produced increases as a result of increased productivity. Textile wastewater contains dyes such as rhodamine B (RhB), which are hazardous and challenging to remove using standard methods. Adsorption utilizing nano-adsorbents has been widely researched and developed to remove dyes from the environment because of its numerous advantages. Graphene oxide-magnetite (GO-Fe3O4) has been extensively explored as an adsorbent due to its large surface area, strong bonding, and ease of separation from water. In this study, GO-Fe3O4 was synthesized by combining GO from coconut shell with Fe3O4 from iron sand as an absorbent to lower the amount of RhB. Various analytical techniques, including XRD, SEM-EDS, TEM, FTIR, and UV-vis, were employed to examine the properties of the composites. The GO-Fe3O4 exhibited a maximum adsorption capacity of 34.590 mg/g under specific conditions, i.e., 0.5 g adsorbent dosage, pH 4, and a 2 h contact time. The adsorption followed the pseudo-second-order kinetics model with 0.00016 mg/g min adsorption rate while the adsorption isotherm followed the Langmuir model where adsorbent surfaces are spread homogeneously by forming a monolayer.

Published: December 2024

Lipstick stains discovered on objects (such as drinking cups) may be utilized as evidence and/or lead in forensic investigations by chemical analysis. Hence, this study analyzed two brands of lipstick stains' organic composition on paper cups over 0, 24, and 48 h of exposure using attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), coupled with pattern recognition techniques of principal component analysis (PCA) and linear discriminant analysis (LDA). Spectral analysis revealed several functional group differences between the two brands of lipstick, viz. Wardah (W) and Silkygirl (S) stains, particularly in the fingerprint region of 1800–650 cm−1. Application of PCA (variance of ≥ 70%) and LDA successfully provided the suitable means for categorically classifying (a) the different brands of lipstick, (b) the male and female volunteers, as well as (c) the different periods of exposure. The fact that the cross-validation correct classification rates for all the LDA models exceeded 90.0%, their suitability for forensic provenance application of lip stains appears statistically supported. Hence, such an approach to combine the non-destructive ATR-FTIR analysis with PCA and LDA is not only easy and cost-effective but also forensically relevant for enabling the data mining process for forensic intelligence.
Reimagining Democracy
Authors: Pedron Stephanie Mae
Published: November 2024

In this brief Conversations essay, I trace how immigrant suffrage in the United States deteriorated in the 19th century and argue that the US should move toward creating a pathway for noncitizen voting for two reasons—a more representative democracy and for a smoother assimilation process into American culture. Noncitizens contribute economically and socially to their communities, and they often have the same investment in their community’s welfare as citizens. Expanding voting rights to noncitizens, even if only at the local-level, would give them a voice in decisions that affect their everyday lives.

El derecho administrativo disciplinario en la administración pública federal mexicana
Authors: Martínez Castañeda Francisco Javier
Published: November 2024

El derecho administrativo disciplinario ha sido poco explorado en México. Sin embargo, en otras partes del mundo, se considera parte del Derecho administrativo sancionador debido a la función de la Administración Pública de imponer sanciones. Este trabajo de investigación subraya la necesidad de reconocerlo como una rama autónoma del Ius puniendi del Estado, ya que cumple con los principios básicos de la materia y tiene normas específicas que lo distinguen significativamente del Derecho penal y el Derecho administrativo sancionador. Además, su procedimiento es diferente de los de estas otras áreas, lo que ha hecho que su estudio sea particular en lugar de general.

Published: December 2024

Introduction. Tinea incognita is a dermatophyte skin infection with atypical clinical presentation modified using previous topical immunosuppressive therapy. Case outline. We present a 59-year-old female patient with a pruritic rash on her face. Over three months, she was misdiagnosed with rosacea, contact dermatitis, and atopic dermatitis, and treated with various topical steroids, metronidazole cream, oral antihistamines, dexamethasone, and methylprednisolone. At the first examination in our clinic, she had a pruritic widespread erythema, papules, and plaques on the face, eyelids, and neck, and a few plaques on the chest and extremities (covered with a thick layer of corticosteroid ointment), resembling various skin conditions. Two days after the exclusion of topical treatment, sharply demarcated erythematous lesions with raised scaly edges and numerous pustules appeared. Fungal culture was positive for Trichophyton mentagrophytes var. granulosum. A skin biopsy confirmed dermatophyte fungal infection, and the lesions resolved after systemic and topical antifungal therapy. Conclusion. We present the case of an unrecognized fungal infection of the skin to highlight the importance of a simple laboratory examination of fungal smears and culture before prescribing topical steroids and other immunosuppressive agents in order to avoid misdiagnosis and inappropriate treatment of patients in the future.

Published: December 2024

Data analytics are regarded as indispensable in enhancing auditor performance in the era of rapid technology advancements and Big Data. We examine the extent to which social support facilitates internal auditor adoption of data analytics, and whether the use of data analytics is associated with performance. Using a unique proprietary dataset from a large insurance company in the U.S., we document that peer social support developed through coparticipation in company trainings, accelerates the adoption of data analytics in various internal audit tasks including continuous auditing, communication, aligning risks and controls, and aligning data analytics with business control objectives. Further, the extent to which data analytics are used is positively associated with several dimensions of auditor performance including internal audit skills, communication skills, and business knowledge. These findings inform research and practice about effective mechanisms that induce auditors’ use of data analytics and the benefits of data analytics in internal audits.
Employees’ Reactions to Algorithmic Performance Evaluation: Threat of Evaluation Bias and Objectivity
Authors: Cha Yunshil
Published: December 2024

Although algorithms are increasingly used for performance evaluation purposes, prior algorithm research shows that individuals tend to trust human decisions more than algorithmic decisions in a subjective domain such as performance evaluation that requires human skills. I conduct an experiment to examine whether the effect of evaluator type (algorithm versus human supervisor) on employees’ perceived trustworthiness of performance evaluations hinges on evaluation bias (positive versus negative) and further investigate whether this interaction effect is mediated by perceived objectivity. I find that employees’ perceived trustworthiness shifts from human evaluations to algorithmic evaluations when negative evaluation bias exists. Further, this reduced algorithm aversion is stronger and significant for people who are vulnerable to evaluation bias because people perceive algorithms as making objective evaluation decisions. Overall, results of this study suggest that the threat of evaluation bias reduces algorithm aversion because of the higher perceived objectivity of algorithmic decisions.

Corporate Governance and Efficiency of Retirement Benefits Schemes in Kenya
Authors: Namagwa Sylvester Willys , Nyamute Winnie , Okiro Kennedy
Published: November 2024

This paper endeavored to establish the effect of corporate governance on the efficiency of retirement benefits schemes in Kenya. Agency theory, stakeholder theory, financial distress theory, and transactional cost theory buttressed the study. The study employed a quantitative research design, utilizing panel regression analysis to test the hypotheses. Data was collected from 896 observations across 128 retirement benefit schemes in Kenya, covering a seven-year period from 2015 to 2021. The research findings revealed that employee representatives on the board significantly and positively influenced the efficiency of retirement benefit schemes. Conversely, independent board members were found to have a negative effect on efficiency, suggesting potential challenges such as conflicts or slower decision-making processes. This study contributes to agency theory by providing empirical evidence that highlights the complexities of board composition in aligning the interests of managers and stakeholders within retirement benefit schemes. For policymakers, the study recommends the development of regulations that mandate or strongly encourage the inclusion of employee representatives on the boards of retirement benefits schemes.
Supporting Tenure-Seeking Faculty in Online Programs: A Critical Discourse Analysis
Authors: Earnshaw Yvonne , Bodine Al-Sharif Mary Ann
Published: December 2024

Very little research has been conducted on the tenure-seeking faculty experience for those teaching in online programs. The majority of the research in this area focuses on their work in the online classroom but not on them as individuals in relation to the academy as a whole. This would include their needed support for tenure and promotion, while also taking into consideration the variation in their workload due to the online modality and interactions with students and colleagues. Online faculty often need a more balanced workload that is thoughtful of the timing of their service placements, office hours, and teaching schedules, as well as mentorship and guidance for professional development. Likewise, these individuals desire greater mentorship to aid in navigating institutional policies and practices. There may be a lack of understanding related to what their typical work week really looks like and the types of support that would best meet their needs. Our work has created a safer space for these individuals who are tenure-seeking faculty in online programs struggling with these exact issues to provide insight into their lived experiences and share with us some of their basic needs to be holistically supported as they move forward in their fields.

Os resíduos sólidos são todos aqueles que se encontram no estado sólido ou semissólido resultantes de atividades domésticas, hospitalares, industriais, comerciais e agrícolas, além de serviços de varrição e lodos provenientes de estações de tratamento de água e equipamentos de controle de poluições. A sociedade e os processos produtivos estão gerando progressivamente mais resíduos sólidos, cujos quais são descartados, comumente, de forma inadequada e sem controle, causando impactos ao meio ambiente. O estudo objetivou analisar o efeito da implementação da Política Nacional de Resíduos Sólidos na gestão ambiental e gerenciamento de resíduos sólidos. A partir de revisão integrativa, realizada pela base de dados da plataforma CAPES, utilizando-se das palavras-chave “PNRS” e “Gestão Ambiental”, foram selecionados os trabalhos que seguiram os critérios de elegibilidade estabelecidos: a publicação estar disponível gratuitamente na internet no idioma português e ser datado dos últimos 10 anos (2013-2023), inteiramente relacionados com o tema de interesse. Obrigatoriamente, os artigos selecionados deveriam conter em seu corpo um estudo sobre a Política Nacional de Resíduos Sólidos e sua aplicação e responderem à pergunta norteadora “Qual a evolução e cenário atual no âmbito de gestão ambiental após a implementação da Política Nacional de Resíduos Sólidos no Brasil?”. Após análise dos artigos, notou-se que a maioria dos trabalhos apresentaram fraqueza na aplicação dos princípios da Política Nacional de Resíduos Sólidos devido à falta de atuação do poder público e da disponibilização de recursos financeiros, principalmente em municípios de pequeno porte – que enfrentam maiores dificuldades para a adequação às normas estabelecidas na PNRS. Neste conjunto de circunstâncias, a gestão de resíduos sólidos no Brasil ainda se apresenta como um desafio para o poder público e sociedade como um todo. É importante que a gestão apropriada de resíduos sólidos seja tida como prioridade para a redução dos impactos ambientais causados pelo seu manejo e disposição inadequados.

The purpose of this study was to examine the technostress levels of science field faculty members in the Kyrgyz Republic. The relational survey model was used to investigate whether there was a significant difference and a relationship between demographic variables such as gender, age, field of science, seniority, technological education level, and availability of a personal computer in terms of technostress and its sub-dimensions. The sample of the study consisted of 274 science faculty members, with 156 females and 118 males working at different universities in the Kyrgyz Republic. “Personal Data Form” and “Defining Teachers’ Technostress Levels Scale” were used as data collection tools in the study. The results showed that the general technostress levels of the participants were at a medium level. General technostress levels and technostress sub-dimensions scores of science faculty members did not differ by their genders, ages, seniorities, technology educations, and availability of their computers. There was a low level of positive correlation between age and the scores of the occupational and personal sub-dimensions of technostress; It was determined that there was a low-level, positive, statistically significant relationship between the seniority variable and the personal-oriented sub-dimension. It can be concluded that as the year of seniority progresses, academicians' technostress scores also increase. These findings reveal that seniority has certain effects on the technostress levels of academicians, but these effects vary based on sub-dimensions.

Information exchange takes place in every community and the advancement of computers and the use of the Internet has made it simpler for people of all communities to communicate information. Teachers also may share personal experiences, information, and communication with their peers in the profession. They can also improve their expertise and skills. As such, the purpose of the present study was to compare the effect of knowledge sharing via Adobe Connect and Google Meet on English as Foreign Language (EFL) teachers’ creativity. To do so, 60 EFL teachers from 15 high schools were asked to fill the creativity questionnaire. Then, to find the role of the social platforms on EFL teachers’ creativity in their teaching, a week after the treatment, the questionnaire as the posttest was given to the EFL teachers. Next, a semi-structured interview with 20 volunteers sought the Iranian EFL teachers' attitude toward the role of social platforms in their creativity. Overall, the finding indicated that knowledge sharing through Google Meet has more significant effect on EFL teachers’ creativity compared to Adobe Connect. In addition, it was found that the teachers agreed with the positive effect of social platforms on their creativity. The findings have implications for pedagogy as well as further research.

Published: December 2024

Enhancing learning outcomes in Science, Technology, Engineering, and Mathematics (STEM) subjects for primary school students remains a challenge. This meta-analysis, guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), explores Digital Game-Based Learning (DGBL) interventions as a potential solution. Eighteen empirical studies published from 2010 to 2020 were analyzed to identify effective DGBL approaches. Key factors examined include subject disciplines, control treatment, game type, platforms, and intervention duration. Findings reveal significant positive effects of DGBL interventions on learning outcomes, particularly in mathematics, language, and science. The study underscores the importance of optimizing gameplay design and platform choices for DGBL effectiveness and highlights the potential benefits of incorporating DGBL into primary STEM education. Future research should further investigate contributing factors like game genres, technologies, implementation strategies, and specific game components to promote optimal learning processes in diverse educational settings.
Deformation by Pressure Solution and Grain Boundary Sliding in a Retrograde Shear Zone in Southern New England, USA

Published: December 2024

Alleghanian phyllonites in a shear zone in southern New England were formed by the retrogression and hydration of a high-grade Acadian pelitic schist. The retrogression was locally incomplete, resulting in both heterogeneous mineralogy and mineral compositions, and in many arrested reaction textures. These features, documented by backscattered electron and element map imaging, and by 40Ar/39Ar dating, provide a record of the processes active as the schist was converted to a phyllonite. On the margins of the shear zone relic biotite and garnet grains survive but are partially replaced by chlorite. Relic high-grade muscovite flakes containing up to 35 % paragonite (pg) also persist but are entrained in swarms of pg-poor muscovite flakes producing folia with an anastomosing network of muscovite grains of variable composition. Single crystals of pg-rich muscovite are truncated by muscovite in successively younger cross-cutting folia that contain decreasing pg contents, falling to <5% pg in the youngest folia. In the core of the shear zone all high-grade minerals are destroyed, but recrystallization continues with earlier greenschist facies folia replaced by lower grade and pg-poorer muscovite in younger folia. Muscovite grains in truncated folia are commonly kinked and selective recrystallization of muscovite in kink bands to pg-poor-compositions demonstrates that strain energy helped drive recrystallization. The boundaries of these new pg-poor muscovite folia are sharp, and truncations indicate that grain boundary sliding (GBS) involved dissolution. GBS also enabled folding by flexural slip along muscovite grain boundaries. Fold amplitudes increased as chlorite dissolved from fold limbs precipitated in fold hinges producing crescent-shaped saddle-reef-like structures. Together these observations of truncation and replacement by dissolution and precipitation demonstrate that pressure solution and GBS facilitated both the formation of the phyllonitic shear zone and slip along it.

Study aim: This study aimed to investigate the impact of physical activity on the mental health characteristics of a sample of university students from Paraguay, assessing their daily physical activity and the prevalence of depression, anxiety, and stress.

Materials and methods: This observational, descriptive, prospective, cross-sectional study included 317 university students. Participants were assessed using the International Physical Activity Questionnaire (IPAQ) to categorize their physical activity levels and the Depression, Anxiety, and Stress Scale-21 (DASS-21) to measure mental health characteristics. Data analysis utilized descriptive statistics, Pearson’s correlation, and chi-square tests to explore associations between physical activity and mental health outcomes.

Results: The results indicated that 49.5% of the participants were engaged in low levels of physical activity, while 20.2% and 30.3% reported high and moderate activity levels, respectively. Mental health assessments showed high prevalence rates for depression (65.3%), anxiety (68.5%), and stress (66.6%). Inverse correlations were found between total physical activity and each mental health parameter: depression (r = –0.167, p = 0.003), anxiety (r = –0.141, p = 0.012), and stress (r = –0.133 p = 0.018). Thus, higher levels of physical activity were associated with lower levels of depression, anxiety, and stress.

Conclusions: This study confirmed a significant inverse correlation between physical activity and common mental health issues. The promotion of physical activity may be a protective factor against depression, anxiety, and stress in this population. These findings support the need for university health programs to encourage physical activity as a strategic approach to enhance students’ mental health.
