Published: October 2024

Objective The aim of this study was to investigate the association between blood levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) and cognitive impairments among elderly individuals.Methods Peripheral concentration of TNF-α and IL-6 were measured in all subjects. To assess individual cognitive function, the Consortium to Establish a Registry for Alzheimer’s Disease Neuropsychological Assessment Battery (CERAD-NP) was used, and standardized scores (z-scores) were calculated for each test. Cytokine levels were compared between the diagnostic groups, and correlations between blood inflammatory factor levels and z-scores were analyzed.Results The 37 participants included 8 patients with Alzheimer’s disease (AD), 15 subjects with mild cognitive impairment (MCI), and 14 cognitively healthy controls. TNF-α and IL-6 levels were higher in patients with AD than in healthy controls. TNF-α levels were higher in the AD group than in the MCI group. However, after adjusting for age, the associations between diagnosis and TNF-α and IL-6 were not significant. The higher the plasma IL-6 level, the lower the z-scores on the Boston Naming Test, Word List Learning, Word List Recognition, and Constructional Recall. The higher the serum TNF-α level, the lower the z-scores on the Word List Learning and Constructional Recall. Negative correlation between serum TNF-α level and the z-score on Word List Learning remained significant when age was adjusted.Conclusion The difference in the blood levels of TNF-α and IL-6 between the diagnostic groups may be associated with aging. However, elevated TNF-α levels were associated with worse immediate memory performance, even after adjusting for age.

Published: October 2024

Objective Korea’s transition into a super-aged society brings to the forefront the escalating dementia prevalence and the consequent rise in mortality, highlighting the need for effective end-of-life (EOL) care strategies. Despite legislative advancements, gaps remain in addressing the medical and ethical challenges of EOL care for patients with advanced dementia, particularly in evaluating treatment options like nasogastric tube (NGT) use and mechanical ventilation (MV). This study investigates the attitudes of the general population (GP) and clinicians in Korea towards EOL treatment decisions.Methods A cross-sectional, web-based survey was conducted among 500 members of the GP and 200 clinicians from a university hospital. Case vignettes were used to assess attitudes towards EOL treatment decisions, specifically focusing on NGT and MV use, and to explore the influencing factors.Results There was a notable difference in favorable attitudes toward NGT withdrawal between the GP (62.2%) and clinicians (39.0%). Otherwise, both groups showed higher acceptance of MV withholding (82.2% [GPs] and 82.5% [clinicians]) when informed of the patient’s verbal intention regarding life-sustaining treatment (LST), and attitudes were more positive with written advance directives. Also, it was decreased when patient intentions were unclear.Conclusion The results suggested the need to consider NGT as a medical intervention requiring a risk-benefit analysis. Although LST decision-making in patients with advanced dementia is still limited in Korea, this study showed the shared recognition among the GP and clinicians of the importance of EOL treatment decisions that consider patient wishes and quality of life for patients with advanced dementia.

Published: October 2024

Objective Observational studies often report disturbed sleep patterns in individuals with diabetic nephropathy (DN). The possible causal relationship behind these connections remains unknown. This research assessed the possible cause-and-effect relationship between eleven sleep-related characteristics and the risk of developing DN using a two-sample Mendelian randomization (MR) study.Methods This study employed a two-sample bidirectional MR analytical approach. Genetic data for eleven sleep-related characteristics were acquired from the genome-wide association studies (GWAS) database of individuals of European ancestry which involve scanning complete sets of DNA, or genomes. GWAS summary data for DN included 4,111 DN cases and 308,539 controls. Instrumental variables were single nucleotide polymorphisms strongly linked to sleep-related characteristics. The main analysis used the random-effects inverse variance weighted (IVW) approach, with validation through sensitivity testing.Results MR analysis revealed that a higher genetic predisposition for sleep efficiency reduced the chance of developing DN (odds ratio [OR]: 0.384; 95% confidence interval [CI] 0.205–0.717; p=0.003). Genetic susceptibility to DN was associated with a higher likelihood of experiencing more sleep episodes (OR: 1.015; 95% CI 1.003–1.028; p=0.016). Sensitivity analysis confirmed the robustness of these correlations. No significant connections were found between other genetically predicted sleep characteristics and the likelihood of developing DN.Conclusion Our research indicates that a genetic predisposition for better sleep efficiency is linked to a lower risk of developing DN. There is also evidence suggesting that genetic predisposition to DN may directly impact sleep episodes. Further research is needed to explore the molecular mechanisms underlying these findings.

Published: October 2024

Представлены результаты анализа методом ГХ-МС жирных кислот атеросклеротических бляшек, полученных при эндартерэктомии артерий пациентов. В результате анализа гексанового экстракта бляшек обнаружены высокие уровни 11- и 15-гидроксиэйкозатетраеновых кислот во всех атеросклеротических бляшках (n = 9). Низкие уровни 9-оксооктадекановой кислоты выявлены во всех образцах, тогда как 13-оксооктадекадиеновой кислоты — только в 4 из 9 образцов бляшек. Интерес представляла идентификация 2 ранее неидентифицированных соединений в атеросклеротической бляшке: 11-оксоэйкозатетраеновой кислоты в 8 из 9 образцов и 5,6-дигидроксиэйкозатетраеновой кислоты в 3 образцах. В растворах трипсина и пепсина в бляшках отмечен высокий уровень стеариновой и олеиновой кислот, который, по-видимому, может индуцировать атеросклеротический процесс. Оценку жирнокислотного состава бляшек для выявления биомаркеров атеросклероза и мишеней для терапевтических воздействий следует считать перспективным.

Dialog Hukum Adat dan Islam: Kritik Syeikh Ahmad Khatib Al-Minangkabawi Terhadap Sistem Waris di Minangkabau
Authors: Arif Muhammad Fahmil , Rahmi Melvi , Firdaus Beni , Endriyenti Endriyenti
Published: October 2024

This research discusses the two main forces influencing Minangkabau society, namely custom and religion. The matrilineal system practiced in Minangkabau has significant differences compared to the Islamic kinship system, particularly in terms of inheritance distribution. These differences often become a source of conflict and academic interest, especially among scholars of Islamic law. One figure who firmly opposes the customary inheritance system in Minangkabau is Sheikh Ahmad Khatib al-Minangkabawi, a prominent scholar who served as Imam, Khatib, and teacher in Mecca. This study employs a library research approach with a descriptive analytical method to explore Sheikh Ahmad Khatib's critiques of the prevailing inheritance system. Sheikh Ahmad Khatib argues that customary practices that divert inheritance to nephews rather than biological children contradict Islamic principles. He even equates this action with consuming the wealth of orphans, a deed prohibited in Islam. During his time, there was ambiguity regarding the ownership status of property in Minangkabau society whether it belonged to a father or was property of the clan managed by the niniak mamak. When a father passed away, the inheritance that should rightfully go to biological children often ended up with nephews, leading to injustice. Sheikh Ahmad Khatib's sharp criticism emphasizes the need for reform in the customary inheritance system to align it with Islamic law and protect the rights of children, thereby reducing conflict and injustice in Minangkabau society in the future.

The determination of child support rights in the Bangkinang Religious Court following the issuance of SEMA Number 4 of 2016, as well as to evaluate the implementation of child support determinations according to the theory of legal certainty. This study is a field research conducted at the Bangkinang Religious Court, where the author gathers concrete data and information through observations and interviews. The focus of this research is on the implementation of SEMA Number 4 of 2016, particularly regarding the authority of judges in determining child support post-divorce in the divorce lawsuit cases of 2023 at the Bangkinang Religious Court. This is crucial because there are several rulings that do not specifically stipulate the father's obligation to provide for his child. Judges should have the ex officio right to determine the nominal amount of child maintenance that must be borne by the father, in accordance with the provisions outlined in SEMA No. 4 of 2016. The lack of clarity regarding the father's obligation towards children after divorce has the potential to cause legal uncertainty in the fulfilment of child maintenance, which in turn can interfere with the welfare of children after divorce. Therefore, this study recommends that judges provide clearer decisions regarding the amount of child maintenance, while still considering the father's financial capacity. In addition, any regulations or procedures relating to the implementation of court administration need to be carefully considered, given their impact on the welfare of children after the decision.
Provider Hesitancy Toward Single-Session Interventions for Mental Health Problems: Malleability and Implications for Adoption in Routine Care Settings
Authors: Sung Jenna , Sotomayor Ian , Szkody Erica , Schleider Jessica L.
Published: October 2024

Introduction: Despite the promise of SSIs in reducing mental health difficulties, SSIs remain rarely integrated into routine healthcare settings. One set of factors that can preclude or facilitate the implementation of novel service models is provider attitudes, which have not been systematically studied in the SSI context. Accordingly, the objectives of this paper are to: (1) discuss the importance of provider attitudes as a potential barrier or facilitator to the deployment of SSIs in routine healthcare systems; (2) provide evidence on providers’ initial attitudes toward SSIs; and (3) outline recommendations to address attitudes towards SSIs in future implementation efforts. Method: A total of 466 providers rated their attitudes towards SSIs before and immediately after a brief training. The aims and data analytic plan were pre-registered on OSF (https://osf.io/zgvmw/). Results: The average minimum number of sessions providers believed as necessary to yield clinically-significant symptom reductions declined from 11.02 (SD = 23.14) to 4.44 (SD = 9.78) from pre-to-post training. Participants perceived the SSI to be useful (Mpre = 3.92, Mpost = 4.12) at both pre-and-post training. Expectancies of the SSI’s acceptability (Mpre = 3.45, Mpost = 3.76) and effectiveness (Mpre = 2.99, Mpost = 3.59) grew more positive post-training. Perceptions around the SSC’s limitations did not meet the cut- off (Mpre = 3.07, Mpost = 3.10) at both time points. Conclusion. Provider attitudes represent a targetable implementation facilitator to promote the uptake and sustainment of SSIs in routine healthcare settings.
Hallucinations in LLMs: Types, Causes, and Approaches for Enhanced Reliability
Authors: Cleti Meade , Jano Pete
Published: October 2024

Large Language Models (LLMs) have transformed natural language processing and generation, enabling diverse applications ranging from content creation to decision support systems. However, a key challenge they face is hallucination—the generation of content that is factually incorrect, inconsistent, or entirely fabricated, yet often appears coherent and plausible. This survey comprehensively examines hallucinations in LLMs, categorizing them into intrinsic, extrinsic, amalgamated, and non-factual types, and analyzing underlying mechanisms such as knowledge overshadowing and contextual misalignment. We evaluate the impact of hallucinations in critical domains like healthcare, scientific research, and journalism, where misinformation can have serious consequences. On the other hand, we explore the potential for hallucinations to drive creativity in fields like art and design, where unconventional outputs can inspire innovation. The survey also reviews detection methods, including named entity recognition and probability-based approaches, alongside mitigation strategies such as prompt engineering, fine-tuning, and grounding techniques. Additionally, we discuss future research directions, focusing on improved evaluation methods, ethical considerations, and advanced integration techniques to enhance the reliability and ethical use of LLMs. By balancing accuracy with creativity, this survey aims to contribute to the development of more trustworthy and responsible large language models.

ChatGPT Literacy for Fostering Language Proficiency and Writing Skills in ESL/EFL Classrooms
Authors: Pandey Hem Lal , Bhusal Purna Chandra
Published: October 2024

Background: The article posits that ChatGPT literacy functions as a pedagogical imperative to foster the writing skills of English as a Second Language (ESL) and English as a Foreign Language (EFL) students. The goal of the article is to explore key literacy skills that are crucial for the ethical and responsible use of ChatGPT in enhancing the teaching of writing skills to ESL/EFL students.
Method: Drawing upon the theory of Artificial Intelligence (AI) literacy (Dobrin, 2023) and ESL/EFL pedagogy of microlearning activities (Kohnke, 2023), this study employs a method of qualitative content analysis (Krippendroff, 2019) of 23 ChatGPT-generated texts as responses to given prompts. The qualitative analysis and interpretation of the given prompts and ChatGPT’s responses have been discussed in four rubrics, namely parts of speech, sentence formation, paragraph writing, and genre convention.
Result: The result of ChatGPT’s responses led to the findings that four literacy skills—literacy of prompting, literacy of hooking and specifying, literacy of qualifying and quantifying, and literacy of rhetorical situations—are some useful techniques for the use of ChatGPT in advancing ESL/EFL writing skills in various educational contexts.
Conclusion: Integrating ChatGPT into ESL/EFL writing classrooms can be productive for both writing instructors and students, provided that microlearning activities are implemented to enhance the effective, ethical, and responsible use of ChatGPT.
Novelty: The paper demonstrates innovative strategies for using AI writing technology such as ChatGPT and shows the importance of effective prompting literacy for a productive conversation to happen in the writing classroom of ESL/EFL students.
Performance of Closed-Ended Mutual Funds: A Test of Market Efficiency
Authors: Karki Dipendra , Upreti Suresh Kumar
Published: October 2024

Background: Mutual funds, known for aggregating funds from a diverse investor base, play a crucial role in managing small funds smartly. This study evaluates the performance of selected closed-ended mutual funds and examines market efficiency in Nepal.
Methods: Using a descriptive and casual-comparative research design, the study spans forty-eight months from January 15, 2018, to January 14, 2022. Monthly data from five mutual funds are analyzed, with metrics such as the Treynor ratio, Sharpe ratio, and Jensen alpha. The study variables include market returns, assets, expense ratios, fund age, liquidity, and mutual fund returns. Various statistical tests, including correlation analysis, Integrated Ranking Analysis, ANOVA test, t-test, and P-value tests, are conducted to determine the significance and statistical relevance of the study variables.
Results: The findings reveal that mutual fund performance is influenced by factors such as return, age, liquidity, asset, and expense ratio. Expense ratio and age emerge as the most impactful factors, demonstrating a statistically significant relationship with market return (p < 0.05). All selected mutual funds outperform the market return (NEPSE), with Sanima Equity Fund securing the top rank in all three measures.
Conclusion: The Sharpe ratio, Treynor ratio, and Jensen alpha measures for mutual funds surpass those of the market, indicating market inefficiency in its semi-strong form.
Novelty: This study uniquely evaluates closed-ended mutual funds using comprehensive performance metrics, demonstrating their significant outperformance compared to market benchmarks. It underscores their effectiveness in actively managing passive funds and challenges the efficient market hypothesis.
„Miasto-ogród” Żarki. Historia
Authors: Malczewska-Pawelec Dorota
Published: October 2024

The book presents the history of founding of a summer resort, at present known as Żarki Letnisko, located in the Jura Krakowsko-Częstochowska region. The settlement is a very rare example of a successful subdivision of manorial land in the interwar Poland with a view to create a “garden city”, comparable to that of Podkowa Leśna near Warsaw. The process of developing the “garden city” of Żarki is presented against a broad backdrop of ideological, social, and economic transformations taking place in the Second Polish Republic. The book also portrays the founder of the “garden city” of Żarki – Karol Raczyński from Złoty Potok, as well as his wife Stefania and his most famous ancestors coming from aristocratic families of Krasińscy, Braniccy and Raczyńscy. Furthermore, the general concept of “garden city” is discussed, along with its evolution and reception on the Polish lands.

I. Las tensiones del desarrollo cultural
Authors: Nivón Bolán Eduardo
Published: October 2024

Toda reflexión sobre política cultural se refiere en última instancia al ejercicio del poder y la toma de decisiones del estado o de los agentes sociales para definir el curso que ha de seguir ese haz de relaciones de la vida social que identificamos con el nombre cultura. Sin embargo, este señalamiento inicial requiere varias precisiones, siendo la primera la definición de este concepto evanescente que es la política. Con frecuencia nos referimos a que una acción es política, pero no encontramos las palabras exactas para decir por qué lo es. Y es que, al igual que la cultura, la política es difícil de circunscribir, por lo que usamos el concepto para expresar una cualidad, más que para señalar una cosa, es decir, lo utilizaremos con un sentido adjetivo.
