ObjectiveThis study aimed to investigate the combined impact of comorbid chronic diseases and depressive symptoms on the risk of cognitive impairment in middle-aged and older adults populations. It also explored the interaction mechanisms and provided scientific evidence for cognitive health interventions.MethodsData from the 2020 wave of the China Health and Retirement Longitudinal Study (CHARLS) were used, including 16,890 participants aged 45 years and older. Overlap weighting was applied to control for confounding factors such as gender, age, BMI, ADL, and smoking status. Multivariate logistic regression models assessed the combined effect of chronic diseases and depressive symptoms on cognitive impairment risk. Subgroup analyses were conducted to explore gender, age, and education level differences. Sensitivity analyses, including propensity score matching (PSM) and E-value estimation, were performed to evaluate the robustness of the findings.ResultsThe coexistence of chronic diseases and depressive symptoms significantly increased the risk of cognitive impairment, with an adjusted odds ratio (OR) of 1.22 (95% CI: 1.14–1.31, p &lt; 0.05). Subgroup analyses revealed that this combined effect was more pronounced in males, individuals aged ≥60 years, and those with lower education levels (elementary school or below). Overlap weighting effectively balanced baseline characteristics, while sensitivity analyses and E-value calculations confirmed the robustness of the results.ConclusionComorbid chronic diseases and depressive symptoms exert a significant cumulative effect on cognitive impairment risk in middle-aged and older adults populations through complex interaction mechanisms. This study addresses a research gap and provides evidence for personalized disease management and psychological interventions. Future research should further explore the mechanisms of these interactions and validate the findings in diverse populations to enhance generalizability.

IntroductionDespite the growing concern regarding a potential increase in the number of older adults with frailty owing to an aging global population, the characteristics of bimanual coordination in such older adults remain unclear. This study aimed to compare bimanual coordinated movements among community-dwelling older adults with frailty, pre-frailty, and robust health and identify the specific characteristics of these movements in older adults with frailty.MethodsParticipants were categorized into frail, pre-frail, and robust groups based on Kihon Checklist scores. They performed bimanual coordination tasks in-phase (tapping the thumb and index finger together as fast as possible) and anti-phase (alternating the movement between the left and right fingers), and the task parameters were compared among the groups.ResultsThe total travel distance during the anti-phase task in the frail group was significantly shorter than that in the robust group. However, all three groups showed lower finger dexterity during the anti-phase task than in the in-phase task and the left hand than in the right hand.ConclusionOlder adults with frailty exhibit less movement during bimanual coordination tasks than robust older adults, suggesting that such tasks may be useful tools for assessing frailty.

Published: February 2025

This study evaluates the effectiveness of Multi-Energy Calibration (MEC) for multielemental analysis in animal feeds using plasma-based optical emission spectrometry (ICP-OES and MIP-OES). The aim was to improve accuracy in detecting essential minerals by overcoming matrix interferences that affect instrumental techniques. Swine feed samples from different growth stages were analyzed, focusing on essential minerals for animal health and productivity, such as Ca, Co, Cu, Fe, K, Mg, Mn, Na, P, and Zn. The MEC strategy utilizes multiple wavelengths per element, reducing calibration complexity and enhancing accuracy by using only two calibration solutions per sample. Results demonstrate that MEC improves recoveries (80%–105%) when compared to traditional external calibration (EC). The limits of quantification (LOQs) ranged from 0.09 mg kg⁻1 for Mn to 31 mg kg⁻1 for Ca and Na using MEC-ICP-OES, and from 0.08 mg kg⁻1 for Mn to 354 mg kg⁻1 for P using MEC-MIP-OES. For EC, they ranged from 0.4 mg kg⁻1 for Co to 195 mg kg⁻1 for K with ICP-OES and from 2.0 mg kg⁻1 for Mg to 607 mg kg⁻1 for Fe with MIP-OES. MEC provides high precision and matrix-matching capabilities. This makes MEC a reliable method for complex feed matrices, supporting more accurate feed formulations to ensure optimal livestock nutrition.

IntroductionThe circular economy has gained considerable attention within academia and industry as a sustainable alternative to linear economic models that minimize waste and maximize resource value in the production cycle. Despite growing interest in adopting circular economy practices within firms, numerous challenges remain. We address this gap by investigating the barriers to transitioning to a circular economy, as the current implementation in practice often needs to be more complete.MethodsUsing a quantitative approach, this research examines the CE barriers influencing Western Balkans firms to become more environmentally responsible business. The analysis is based on data from the Regional Cooperation Council's Business Balkan Barometer 2024 database, compiled through the Business Opinion Survey, for which logistic regression analysis was employed.ResultsThe findings reveal that firms reporting barriers, such as added costs, lack of skills and experience, lack of consumer demand, and lack of government subsidies, are statistically significant in the probability of becoming more environmentally responsible business. By contrast, the lack of legal and regulatory framework was not found to be significant.DiscussionThe study contributes a comprehensive analysis of these barriers that validate and complement previous research, offering stakeholders within Western Balkan countries an additional perspective to overcome the current challenges, thereby fostering the transition to becoming a more environmentally responsible business.

Published: February 2025

IntroductionThe purpose of this study was to examine how feedback from the coach influences football players' experiences of well-being, mastery, pleasure, satisfaction, development, being seen by the coach, and motivation in two different groups.MethodsThe study used an intervention with a crossover experimental approach, where 95 players aged 14–18 that participated in sports clubs and specialized football classes in a town in Mid-Norway, participated in the same organized training session with the same coach in every session—one without feedback and one with feedback from the coach, answering a questionnaire after each training session. The questionnaire was developed with a total of seven questions with high face validity for each of the variables. The study was approved by the Norwegian data protection agency, and a written informed consent for participation in this study was provided by the participants' legal guardians/next of kin. Wilcoxon nonparametric tests were used to examine differences between the session without and the session with feedback among players in the two groups for each variable.ResultsAnalyzing all players, the results showed that when feedback was given, it led to a significant increase in mastery, the experience of being seen by the coach, and motivation, compared to the same training session when they did not receive feedback. Furthermore, analyzing only players who participated in sports studies with a specialization in football, the results showed that giving feedback led to a significant increase in well-being, pleasure, satisfaction, and development. Finally, analyzing only players who participated in sports teams and did not specialize in football in sports programs showed that when feedback was given, it led to a significant increase in, the experience of being noticed by the coach, and motivation—but a decrease in development, compared to the same training session when they did not receive feedback.DiscussionThis study introduces a unique and novel intervention approach focusing on the effects of feedback. The findings suggest that football coaches' feedback has a positive outcome for several psychological factors of young players. The findings of the study highlight the importance of football coaches' feedback.

IntroductionPrecision farming is an agricultural management practice that addresses various challenges by observing and measuring the variability of field crops, utilizing accurate and timely information about agricultural resources. A fundamental aspect of precision farming is the use of site-specific management zones (SSMZs). SSMZs improve agricultural management by customizing treatments for specific production zones, thereby conserving resources while enhancing crop productivity and quality. This research aimed to investigate the application of magnesium fertilizer in SSMZs for Allium cepa, as opposed to traditional methods based on soil and plant attributes.MethodsTo achieve this, a 10-meter grid-sampling scheme was implemented across the field, comprising 12 points where soil samples were collected from the top 20 cm before planting green onions in June 2021. Normalized Difference Vegetative Index (NDVI) data during the harvest stage of the green onion growth cycle were sourced from Sentinel-2 satellite imagery at each sampling point. Yield mapping was performed at harvest. Key yieldlimiting factors were identified through stepwise multiple analyses, which included soil properties (such as organic matter) and canopy parameters (such as bulb diameter, phosphorus, magnesium, and NDVI).ResultsOverlay maps illustrated soil parameters, growth, and biochemical measurements, and evaluated the effect of foliar spraying with different magnesium sources on the growth, productivity, and quality of green onions, indicating three distinct SSMZs: zone (I), zone (II), and zone (III), with areas of 1.97 ha, 1.35 ha, and 2.79 ha, respectively. The use of magnesium oxide nanoparticles (nMgO) in a site-specific management zone resulted in a remarkable green onion yield of 152.14 tons/ha. The assessed soil properties and plant characteristics revealed that foliar applications of (nMgO) significantly improved the nutritional status, growth, and quality of green onions (Allium cepa L.).DiscussionThe modeling process effectively classified the study area into three management zones for soil treatments and three additional management zones for plant treatments. Implementing such a process will lower the costs of soil analysis and enhance overall agricultural income.

BackgroundBecause of the high rate of recurrence, the prognosis of patients with pancreatic ductal adenocarcinoma (PDAC) is still very poor despite underwent pancreatectomy and adjuvant chemotherapy. A few reports have suggested the feasibility and efficacy of surgical resection for pulmonary metastases of PDAC. However, the role of metastasectomy of recurrent PDAC remains controversial. The aim of this study is to evaluate the benefits of pulmonary metastasectomy in PDAC patients with lung metastases.MethodsWe searched the PubMed, Embase, and Cochrane Library databases and extracted the hazard ratio (HR) with 95% confidence interval (CI) from eligible studies. Pooled HR with 95% CI were used to reveal the association between pulmonary metastasectomy and survival.ResultsThe meta-analysis encompassed data from nine studies, comprising 467 patients suffered PDAC with lung metastasis. The results (the pooled HR: 0.637, 95% CI: 0.531–0.764, I2 = 61.5%, p value = 0.008) indicated that patients with lung metastasis who underwent pulmonary metastasectomy seemed to have better survival when compared with patients who underwent only chemotherapy. The robustness of these pooled results was verified by our subgroup analysis and sensitivity analysis. Moreover, the varying sample sizes among studies contribute to the heterogeneity in the pooled hazard ratio (HR) for survival, as indicated by the meta-regression analysis (p value = 0.045).ConclusionPulmonary metastasectomy could prolong the survival in patients with lung metastases from PDAC. However, the present study is based on a relatively small number of patients and may include a selection bias. More multi-institutional prospective study is needed to evaluated the clinical value of pulmonary metastasectomy.

АЛАНЫ В I ВЕКЕ НАШЕЙ ЭРЫ ПО ПИСЬМЕННЫМ И АРХЕОЛОГИЧЕСКИМ ДАННЫМ
Authors: Берлизов Николай Евгеньевич 
Published: February 2025

Статья посвящена анализу наиболее ранних письменных и археологических источников, связываемых с аланами. Интерес к этому племени внезапно возник у античных литераторов, историков и географов в I в. Они локализовали алан на Нижнем Дунае, в Приазовье и в Закавказье. При этом Иосиф Флавий и Клавдий Птолемей знали алан как часть скифов. Лукиан из Самосаты отмечал тождество внешнего вида скифов и алан. Письменным свидетельствам синхронно распространение в указанных регионах могильников с погребениями в катакомбах, близких по обряду позднескифским с одной стороны и средневековым аланским - с другой. Автор предлагает считать их памятниками ранних алан. Отмечается, что среднесарматская культура, традиционно связываемая с аланами, была уничтожена в начале II в. поздними сарматами, в то время как аланы известны вплоть до татаро-монгольского нашествия.
The article is devoted to the analysis of the earliest written and archaeological sources associated with the Alanians. Ancient writers, historians and geographers suddenly became interested in this tribe in the first century. They localized the Alanians on the Lower Danube, in the Azov Sea and in Transcaucasia. At the same time, Josephus Flavius and Claudius Ptolemy knew the Alanians as part of the Scythians. Lucian of Samosata noted the identity of the appearance of the Scythians and the Alanians. According to written evidence, the simultaneous spread of burial grounds in these regions with burials in catacombs close to the Late Scythian rite on the one hand and the medieval Alanian on the other. The author suggests considering them as monuments of the early Alanians. It is noted that the Middle Sarmatian culture, traditionally associated with the Alanians, was destroyed at the beginning of the II century by the late Sarmatians, while the Alanians were known until the Tatar-Mongol invasion.

Authors: Seydel Ute 
Published: February 2025

La presente contribución analiza diversos poemas de Manuela Ballester reunidos en el poemario Cosas, y su artículo “Mujeres intelectuales”, todos escritos en el primer lustro de la década de 1930. Para poder trazar el desarrollo por el que pasó la creadora –de una joven enamorada que retomaba en sus versos el imaginario tradicional acerca del amor de pareja heterosexual y sobre la maternidad a una mujer comprometida con las luchas sociales y políticas de su tiempo– me baso en el enfoquede Teresa de Lauretis sobre las tecnologías del género. Asimismo, parto de las reflexiones de Graciela Hierro sobre los valores y disvalores tradicionalmente vinculados con el género masculino, por un lado, y el femenino, por otro.
