Prevalencia y factores asociados con los comportamientos sedentarios y la actividad física en escolares de básica primaria

The school and its curricular proposals promote prolonged sedentary behavior, fostering a sedentary behavioral culture that is reinforced extracurricularly, possibly affecting the health of schoolchildren. However, the Physical Education class, and particularly the promotion of school physical activity within it, is one of the most important strategies to mitigate the harmful effects of sedentary behaviors in children. Therefore, the main objective was to establish the prevalence and factors associated with sedentary behaviors in elementary school students. The results reveal that in the school transportation domain, there is an average prevalence of 114 minutes per week of sedentary behavior. In the school environment, walking is common, but sitting time has a weekly average of 1680 ± 102 minutes. Meanwhile, in the home domain, women show higher participation in physical activity. This study highlights the need for school interventions to promote active and healthy habits in childhood.

The Role of Phosphate-Solubilizing Microbial Interactions in Phosphorus Activation and Utilization in Plant-Soil Systems: A Review.

To address the issue of phosphorus limitation in agricultural and forestry production and to identify green and economical alternatives to chemical phosphorus fertilizers, this paper reviews the utilization of phosphorus in plant-soil systems and explores the considerable potential for exploiting endogenous phosphorus resources. The application of phosphate-solubilizing microorganisms (PSMs) is emphasized for their role in phosphorus activation and plant growth promotion. A focus is placed on microbial interactions as an entry point to regulate the functional rhizosphere microbiome, introducing the concept of synthetic communities. This approach aims to deepen the understanding of PSM interactions across plant root, soil, and microbial interfaces, providing a theoretical foundation for the development and application of biological regulation technologies to enhance phosphorus utilization efficiency.

Leveraging intergovernmental data sharing for digital transformation in ecological and environmental protection

The data-sharing problem in the digital transformation of ecological environmental protection is a result of complex interactions and continuous strategic interactions among governments. While existing research has focused on the application and impact of digital technologies in ecological environmental protection, there remains a paucity of micro-level investigations into data sharing among different local governments regarding ecological environment protection. Notably, the issue of data barriers between local governments is particularly prominent. This paper analyzes the data-sharing problem in the digital transformation of ecological environmental protection through an evolutionary game model involving central and local governments, providing new perspectives and methods for understanding and improving data sharing and governance of ecological environmental protection, thereby promoting the digital transformation of the ecological environmental governance system and governance capacity. It finds that six stable equilibrium strategies can form based on local government participation levels, with the superior government's active promotion and regulation being crucial for achieving stable, multi-party participation. Key factors include the superior government's administrative costs and incentives, and local governments' benefits, costs, and risk considerations. The study highlights the importance of benefit-sharing rules and provides optimization strategies for enhancing intergovernmental data sharing.

University Support for Coping with Studying During the Fourth Wave of the Pandemic: A Thematic Analysis of Student Perspectives

This qualitative study, conducted in Poland in January 2022, drew upon the experiences of final semester master’s degree psychology students. Amidst record-high case numbers, these students were asked to provide written statements discussing the stress they experienced in relation to studying during the pandemic and what the university as an organization should offer to support students in coping. The data was analyzed using thematic analysis to identify and interpret patterns regarding the reported stress and proposed solutions for coping. This study spotlighted health concerns, technostress, communication challenges, and the diminished human contact as key sources of stress in remote learning environments. Findings further indicated that stress management could be significantly improved through the proper organization and prompt communication of changes in teaching and examination modes. Furthermore, a clear definition of course requirements and conditions for credit, combined with avenues for student input, emerged as an essential aspect of the university's approach. The study recommends the development of stress management and well-being courses, organization of additional instructor-student meetings, and promotion of social activities to combat isolation. It also underscored the necessity of accessible psychological support, highlighting the potential benefits of interventions such as mindfulness programs. The implementation of these suggestions aims to foster the development of resilient, adaptive, and successful individuals prepared to face the challenges of an increasingly interconnected and technologically-driven world.

Brotherhood and unity: ethnic diversity and economic performance in socialist Yugoslavia

AbstractLiterature on economic consequences of ethnic diversity suggests that ethnic diversity impedes economic growth in dictatorships, while inclusive policies may foster economic benefits from diversity. This paper investigates the impact of ethnic diversity on municipal economic growth in socialist Yugoslavia, a distinctive context due to its dictatorial regime’s active promotion of ethnic inclusion. Utilizing novel estimations of economic performance for 498 municipalities across the census years 1961, 1971, and 1981, the analysis based on seemingly unrelated regressions model reveals that higher ethnic diversity, measured through an ethnic fractionalization index is associated with slower economic growth of Yugoslav municipalities. The study is the first quantitative assessment of the economic consequences of ethnic diversity in Yugoslavia and provides nuanced insights into the effectiveness of inclusive policies, suggesting that while such policies may foster economic benefits, they might not fully counteract the economic drawbacks of ethnic diversity under dictatorship and in an economy that is not primarily driven by market forces.

A superior chitin product: Black soldier fly larvae chitin, beneficial to growth performance, muscle quality and health status of largemouth bass Micropterus salmoides, in comparison to shrimp chitin

We appraised the effects of black soldier fly larvae chitin (BSFC) with four levels (0.4 %, 0.8 %, 1.2 % and 1.6 %) and shrimp chitin (SC) with three levels (0.4 %, 0.8 % and 1.6 %) in diets on the growth performance, nutrient composition and health status of largemouth bass (8.00 ± 0.29 g) fed for 56 days. The results showed that the dietary 0.4 % BSFC distinctly increased the specific growth rate and weight gain rate of fish (P < 0.05), and evidently promoted the deposition of C22:1n-9, C24:1n-9 and increased total monounsaturated fatty acid content in the muscle (P < 0.05). BSFC and SC distinctly stimulated the secretion of β-N-acetylglucosaminidase in the hindgut (P < 0.05). The antioxidant status of fish was improved by BSFC and SC, which was attributed to the decreased malonaldehyde contents in the muscle and midgut and the increased total superoxide dismutase and catalase activities in the midgut. The 1.2 %–1.6 % BSFC and 0.8 %–1.6 % SC enhanced the non-specific immunity of fish, which was attributed to the marked promotion of lysozyme, acid phosphatase and alkaline phosphatase activities by BSFC and the distinct enhancement of lysozyme activity by SC in the serum or midgut (P < 0.05). BSFC and SC notably reduced the abundance of potential pathogenic bacterium Vibrio and Photobacterium (P < 0.05), and 0.4 %, 1.2 %, 1.6 % BSFC and 0.4 % SC markedly increased the abundance of probiotic bacterium Cetobacterium (P < 0.05), and the BSFC and SC of 0.8 % significantly increased the abundance of the probiotics Bifidobacterium and Bacillus respectively (P < 0.05). The increase of acetic acid, propionic acid, butyric acid and valeric acid concentrations in the hindgut might be related to the increase of intestinal probiotics, and 0.8 %–1.6 % BSFC and 0.4 % SC obviously increased the total short-chain fatty acid levels in the hindgut (P < 0.05). BSFC and SC remarkably reduced muscle fiber area and diameter (P < 0.05), while fiber densities were significantly increased under 0.4 %, 0.8 % BSFC and 0.4 % SC supplementation (P < 0.05), which was accordant with increased mRNA expression levels of myod, myf-5, smad-2, tgf-β1 and decreased mRNA expression levels of myos in the muscle. Collectively, BSFC and SC had no negative effect on the growth of largemouth bass, and improved the health status of fish. The dietary 0.4 % BSFC supplementation was beneficial to fish growth and muscle quality, and BSFC was a superior chitin product in comparison to SC.

Lifestyle and Cardiometabolic Risk Factors Associated with Impoverishment Due to Out-of-Pocket Health Expenditure in São Paulo City, Brazil.

The rise in obesity and related chronic noncommunicable diseases (NCDs) during recent decades in Brazil has been associated with increases in the financial burden and risk of impoverishment due to out-of-pocket (OOP) health expenditure. Thus, this study investigated trends and predictors associated with impoverishment due to health expenditure, in the population of São Paulo city, Brazil, between 2003 and 2015. Household data from the São Paulo Health Survey (n = 5475) were used to estimate impoverishment linked to OOP health expenses, using the three thresholds of International Poverty Lines (IPLs) defined by the World Bank at 1.90, 3.20, and 5.50 dollars per capita per day purchasing power parity (PPP) in 2011. The results indicated a high incidence of impoverishment due to OOP disbursements for health care throughout the period, predominantly concentrated among low-income individuals. Lifestyle choices referring to leisure-time physical activity (OR = 0.766 at $3.20 IPL, and OR = 0.789 at $5.50 IPL) were linked to reduction in the risk for impoverishment due to OOP health expenditures whilst there were increases in the probability of impoverishment due to cardiometabolic risk factors referring to obesity (OR = 1.588 at $3.20 IPL, and OR = 1.633 at $5.50 IPL), and diagnosis of cardiovascular diseases (OR = 2.268 at $1.90 IPL, OR = 1.967 at $3.20 IPL, and OR = 1.936 at $5.50 IPL). Diagnosis of type 2 diabetes mellitus was associated with an increase in the probability of impoverishment at only the $1.90 IPL (OR = 2.506), whilst coefficients for high blood pressure presented lack of significance in the models. Health policies should focus on interventions for prevention of obesity to ensure the financial protection of the population in São Paulo city, Brazil, especially targeting modifiable lifestyle choices like promotion of physical activity and reduction of tobacco use.

Innovation Success in the European Union: Aggregate Demand Analysis

In the current period of uncertainty in the European Union, innovation is becoming a key factor for maintaining not only economic stability but also competitiveness in the globalised environment. Following the financial crisis that hit Europe, aggregate demand indicators slowly started to stabilise, mostly reaching their peak in 2019. However, in the following year, due to the pandemic crisis, these indicators fell again, posing a new challenge for researchers around the world. This study examines the relationship between macroeconomic indicators of aggregate demand and innovation performance in 25 EU countries. Using data for the period 2013-2021 as input for the regression analysis, the research identifies firm investment and exports as important innovation support factors and highlights their key role. On the other hand, the research shows that household consumption and imports are barriers to innovation. Somewhat surprisingly, government spending on goods and services does not have a significant impact on innovation success, underlining the need to rethink government investment policies. This finding highlights the need for a more thorough analysis of the effectiveness of state investment in innovation and possible adjustments to state policies to maximise the promotion of innovation activities in the state. The study also highlights the importance of comprehensive strategies that promote investment and exports, while emphasising the removal of barriers to innovation in the form of household consumption and imports.

Effect of climate, crop, and management on soil phosphatase activity in croplands: A global investigation and relationships with crop yield

Agricultural and livestock production cover more than a third of the Earth's land surface and are crucial to food supply. Soil extracellular enzymes play an important role in the transformation of elements and compounds in soil, particularly acid (ACP) and alkaline (ALP) phosphatases (both, APases). These enzymes have a vital role in releasing phosphorus (P) from organic matter. However, the effect of climate variables and agro-ecosystem management on APase activity in croplands remains unclear, as does its eventual relationship with agricultural productivity. Therefore, we compiled a global database of APase activity in croplands (between 1977 and 2022) and we analysed 5876 observations across 474 papers to study climate variables, crop family, and management effects on ACP and ALP activity, and their relationship with yield. ACP activity is reduced by higher temperatures (p<0.001) and lower rainfall (p=0.002). There was an interaction effect of temperature and precipitation on ALP activity (p=0.046), with the negative effect of temperature being stronger with high precipitation, and low precipitation showing low ALP activity levels at any temperature. The crop family greatly influenced APase activity (p<0.001). Management practices affected ACP and ALP activity differently; ACP activity was positively influenced by organic fertilization combined with, crop rotation or irrigation by an average of 15.6 % and 30.7 %, respectively. ALP activity was mainly positively influenced by the interaction of two different factors: organic or inorganic-organic fertilization and reduced or zero tillage. Further understanding of soil enzyme mechanisms would aid global food security and yield. As ACP activity doubles from 100.0 to 200.0 mg pNP kg−1h−1, the crop yield increases by more than two-fold, an outcome not demonstrated in croplands until now. These results could enhance yield potential through the promotion of APase activity, and the consideration of climate variables and agro-ecosystem management, which could ultimately improve cost-benefit ratios for sustainable crop growth.

Impact of a Clinical Placement on Pre-Professional Health Students Perceived Knowledge, Skills, and Confidence in the Delivery of Behaviour Change and Physical Activity Support

Background: Clinical placements may provide an appropriate setting for health professional students to learn and apply skills for supporting clients to improve their physical activity. Methods: A mixed methods study was conducted with pre-professional health students completing clinical placement at one of two interprofessional community clinics. Surveys assessed student self-reported perceived skills, knowledge, and confidence for behaviour change and physical activity support pre- and post-placement (unmatched n=40). Interviews were conducted with students (n=18) and clinical educators (n=4). Change in student knowledge, skills, and confidence were assessed using non-parametric tests; qualitative data underwent inductive thematic analysis. Results: Post-placement, unmatched participants perceived knowledge and understanding (p = 0.017), skills (p = 0.001), and confidence (p = 0.004) in behaviour change significantly increased. Perceived confidence in providing physical activity behavior change support for low-risk (p = 0.022) and complex conditions (p = 0.009) significantly improved. Qualitative data emphasised the importance of clinical educators and direct clinical experiences in preparing students for future practice. Conclusion: Student-facilitated interprofessional clinical placements may be important for developing pre-professional knowledge, skills, and confidence in delivering behaviour change and physical activity support. Further exploration of clinical placement opportunities for strengthening pre-professional health students training in physical activity promotion and behaviour change is recommended.

Comprehensive School Physical Activity Programming in Dubai International Schools: A Mixed Methods Study

The purpose of this study was to examine comprehensive school physical activity program (CSPAP) policies and practices in interna-tional schools in Dubai, the United Arab Emirates. Following an ex-planatory-sequential mixed-methods research design, the researchers employed the Comprehensive School Physical Activity Program Policies and Practices Questionnaire (CSPAP-Q) and follow-up interviews to describe CSPAP implementation and explore implementation enablers and challenges. A convenience sample of physical education teachers (N=18) participated in the questionnaire, and seven of these teachers participated in individual interviews. Teachers’ responses to the ques-tionnaire indicated considerable heterogeneity and numerous gaps in existing school-based physical activity opportunities and promotion O'Reilly and Websterefforts. Interviews revealed three themes related to CSPAP implemen-tation: (a) time constraints in secondary schools, (b) facilities, and (c) location. This study provides an initial glimpse into whole-of-school physical activity programming in Dubai international schools.

Knowledge, attitudes, practices, and barriers of oncology nurses in promoting physical activity in cancer survivors: a cross-sectional survey in China

PurposeTo explore the knowledge, attitudes, and practices of Chinese nurses in promoting physical activity among cancer survivors and the relationships between these attributes and to identify the factors hindering nurses’ clinical practice.MethodsNurses from oncology-related departments of 10 public tertiary hospitals in Shandong Province completed self-administered questionnaires that included information about demographics; knowledge, attitudes, and practices of physical activity promotion; and barriers to clinical practice. The STROBE statement for observational studies was applied.ResultsA total of 502 valid questionnaires were obtained. The average standardized scores of knowledges, attitudes, and practice were 75.33%, 82.36%, and 62.60%, respectively. Oncology specialist nurses and nurses who had received relevant training had higher levels of knowledge, nurses from general hospitals reported higher levels of practice, and nurses who had learned the relevant guidelines were better in terms of knowledge, attitude, and level of practice. Attitude had a statistically significant mediating effect between knowledge and practice. Lack of time, lack of multidisciplinary clinical teams, and lack of clear guidelines were the most frequently reported barriers to practice.ConclusionIn China, nurses have a moderate level of knowledge and practice in promoting physical activity among cancer survivors, but a positive attitude. Numerous barrier factors present challenges in nurses’ clinical practice. Attitude plays a partial mediating role between knowledge and practice.

RNA Polymerase II coordinates histone deacetylation at active promoters.

Nucleosomes at actively transcribed promoters have specific histone post-transcriptional modifications and histone variants. These features are thought to contribute to the formation and maintenance of a permissive chromatin environment. Recent reports have drawn conflicting conclusions about whether these histone modifications depend on transcription. We used triptolide to inhibit transcription initiation and degrade RNA Polymerase II and interrogated the effect on histone modifications. Transcription initiation was dispensable for de novo and steady-state histone acetylation at transcription start sites (TSSs) and enhancers. However, at steady state, blocking transcription initiation increased the levels of histone acetylation and H2AZ incorporation at active TSSs. These results demonstrate that deposition of specific histone modifications at TSSs is not dependent on transcription and that transcription limits the maintenance of these marks.

Dissection of core promoter syntax through single nucleotide resolution modeling of transcription initiation.

How the DNA sequence of cis-regulatory elements encode transcription initiation patterns remains poorly understood. Here we introduce CLIPNET, a deep learning model trained on population-scale PRO-cap data that predicts the position and quantity of transcription initiation with single nucleotide resolution from DNA sequence more accurately than existing approaches. Interpretation of CLIPNET revealed a complex regulatory syntax consisting of DNA-protein interactions in five major positions between -200 and +50 bp relative to the transcription start site, as well as more subtle positional preferences among transcriptional activators. Transcriptional activator and core promoter motifs work non-additively to encode distinct aspects of initiation, with the former driving initiation quantity and the latter initiation position. We identified core promoter motifs that explain initiation patterns in the majority of promoters and enhancers, including DPR motifs and AT-rich TBP binding sequences in TATA-less promoters. Our results provide insights into the sequence architecture governing transcription initiation.

Designing 2D carbon dot nanoreactors for alcohol oxidation coupled with hydrogen evolution

The coupled green energy and chemical production by photocatalysis represents a promising sustainable pathway, which poses great challenges for the multifunction integration of catalytic systems. Here we show a promising green photocatalyst design using Cu-ZnIn2S4 nanosheets and carbon dots as building units, which enables the integration of reaction, mass transfer, and separation functions in the nano-space, mimicking a nanoreactor. This function integration results in great activity promotion for benzyl alcohol oxidation coupled H2 production, with H2/benzaldehyde production rates of 45.95/46.47 mmol g−1 h−1, 36.87 and 36.73 times to pure ZnIn2S4, respectively, owning to the enhanced charge accumulation and mass transfer according to in-situ spectroscopies and computational simulations of the built-in electrical field. Near-unity selectivity of benzaldehyde is achieved via the effective separation enabled by the Cu(II)-mediated conformation flipping of the intermediates and subsequent π-π conjugation. This work demonstrates an inspiring proof-of-concept nanoreactor design of photocatalysts for coupled sustainable systems.

Promoting Physical Activity in Huntington's Disease: Co-Design of a Care Partner Resource.

Clinical guidelines recommend that people with Huntington's disease (HD) should exercise to maintain/improve fitness and motor function, yet physical activity levels remain low in this group. Promotion of physical activity is often via care partners with little evidence that they are supported in this role. The aim was to co-design a resource for care partners of people with HD to support promotion of physical activity. A four-step co-design approach was used to develop a care partner resource. Five care partners took part in an online workshop exploring experiences and the knowledge, support and skills needed by care partners to promote physical activity. A co-design team (n = 7) developed a prototype that was user tested by three people who had attended the workshop. Findings from user testing were used to develop the final resource. An easy to read, image-based prototype was developed that contained tips on planning activity, safety and activity examples. User testing identified the need for grouping of activities suitable for 10, 20, and 30 minutes of available time, information on maintaining and improving activity and re-organization of information to support engagement of activity. A resource for care partners that has been translated into seven languages was developed to promote physical activity. User testing indicated confidence in using the resource and appreciation of the autonomy provided to the person with HD to plan activities. Further work is needed to evaluate the impact of the resource in promotion of physical activity and the impact on care partner burden.

The impact of fear of falling on health-related quality of life in community-dwelling older adults: mediating effects of depression and moderated mediation effects of physical activity

BackgroundThe fear of falling is a common issue among older adults that negatively affects physical and psychological aspects of health-related quality of life, regardless of actual fall events. Interventions aimed at reducing fear of falling, independent of falls, may improve older adults’ quality of life. This study examined the moderated mediation effect of physical activity in how fear of falling affects health-related quality of life through depression in community-dwelling older adults.MethodsThis study used secondary data from the Korea Centers for Disease Control and Prevention’s 2019 Community Health Survey. The study included 73,738 adults aged 65 years or older. The researchers used the fear of falling scale, International Physical Activity Questionnaire, Patient Health Questionnaire-9, and EuroQol 5 Dimension as research tools, and performed descriptive statistics, Pearson’s correlation coefficient, and SPSS PROCESS macro analysis. The study used the bootstrapping method to assess the adjusted mediating effect by resampling 5,000 times, and determined statistical significance with a 95% confidence interval.ResultsIn the model in which fear of falling affects health-related quality of life by mediating depression, the moderated mediation effect of physical activity was statistically significant, as the bootstrapping result did not include 0 in the 95% confidence interval (Index of moderated mediation [95% CI] = 0.006 [0.004–0.007], 0.008 [0.006–0.009]). Depression and health-related quality of life impairment decreased as the level of physical activity increased through inactivity, minimal activity, and health promotion activities, as the negative mediating effects decreased.ConclusionPhysical activity reduces depression and improves health-related quality of life by influencing older adults’ fear of falling. Community-based programs are needed to encourage and support older adults in maintaining moderate physical activity to manage the depression caused by fear of falling, which is common among older adults, and to improve their health-related quality of life.

Selective hydrogenation of acetylene over Pd/β-Mo2C catalyst: Experimental and theoretical studies

Molybdenum carbide is a promising support to tune the metal reactivity, which originates from the interaction between metal and support. In this work, Pd/β-Mo2C was prepared using a deposition-precipitation method for selective hydrogenation of acetylene. The high temperature calcination is employed to modulate the interaction between Pd and β-Mo2C. The Pd/β-Mo2C catalyst calcined at 600 °C exhibits significant promotion in selective hydrogenation, which shows 100 % acetylene conversion and 81.4 % ethylene selectivity at 160 °C. The activity promotion originates from the enhanced electronic metal-support interaction, which induces a shift of Pd 3d to higher binding energy. Besides, the Pd species become atomically dispersed after calcination. The changes in geometric and electronic structure suppress the formation of Pd hydrides, which consequently inhibits the excessive hydrogenation capacity of Pd. The structure variation also affects the adsorption of ethylene. No strong adsorbed ethylene (di-σ bonded ethylene) can be identified, which is conducive to the improvement of ethylene selectivity. Density functional theoretical (DFT) calculations confirm that Pd on β-Mo2C is positively charged. The desorption energy of C2H4* (0.78 eV) is significantly lower than that of further hydrogenation (1.45 eV), which explains the improved ethylene selectivity of the calcinated catalyst. The present study indicates calcination is an effective method to tune the activity of Pd/β-Mo2C for reactions beyond selective hydrogenation of acetylene.

Preliminary Effectiveness of a One-Week Summer Day Camp for Improving Children's Health Behaviors and Psychosocial Well-Being Outcomes.

Summer day camp offers children opportunities to grow knowledge and skills, be physically active, and have fun. Compared to healthy children, at-risk children (i.e., overweight, or with obesity and chronic health conditions) typically display less optimal health behaviors and psychosocial well-being, especially during summer months. This study examined the preliminary effectiveness of an American-Diabetes-Association-sponsored summer day camp at improving children's health behaviors (i.e., physical activity, screen time, diet, sleep) and psychosocial well-being outcomes (i.e., quality of life [QoL], enjoyment, weight-related self-efficacy). The sample consisted of 39 participants, including 19 boys and 20 girls, with majority being overweight (n = 4 or 10%) or with obesity (n = 26 or 67%), who attended the day camp for one week. Significant improvements were observed in screen time, quality of life, and physical function. The results further showed significant time by gender interaction effect for overall QoL (p < 0.05, ηp2 = 0.15), physical health (a dimension of QoL; p < 0.05, ηp2 = 0.18), and significant time by household income for the psychosocial health (another dimension of QoL), favoring boys and those from higher income families. The findings indicate a positive preliminary effectiveness of the summer camp at reducing children's screen time and improving their QoL, especially in boys and those from higher-income families. Future research should focus on health disparities and expansion of this camp for the potential of longer-term and more robust effects related to wellness, nutrition literacy, physical activity promotion, and obesity prevention.
