Aim: Apart from the obvious health consequences, diabetes mellitus leads in unfavorable psychological responses that can lead to emotional problems. Individual coping techniques for lowering stress and making treatment decisions in which spirituality plays a significant role. The study aimed was to determine the relationship between spirituality and the coping mechanisms of type 2 diabetes mellitus patients.
Methods: This is correlational study with cross-sectional approach. Total sampling was used to collect data from 54 people diagnosed with type 2 diabetes. The spirituality instrument uses the Daily Spiritual Experience Scale (DSES) and the coping mechanism uses The Brief Cope. Statistical analysis using chi-square.
Results: The results showed that most respondents had moderate spirituality (59,3%) and adaptive coping mechanisms (55.6%). The chi-square test results obtained a P-value of 0.008, so there is a relationship between spirituality and coping mechanisms in type 2 DM patients.
Conclusion: The results showed that most of the respondents had moderate spirituality and adaptive coping mechanisms. Spirituality and adaptive coping skills are predicted to be enhanced by nurses, particularly in populations at risk for chronic disease.

Published: February 2023

Most polymer materials are thermal and electrical insulators, which have wide potential in advanced energy-power applications including energy conversion. However, polymers get softened when in contact with heat, which causes their molecular chains to flow as the temperature increases. Although polymer dielectrics exhibit high power density, they face challenges of low energy density which is due to the low dielectric permittivity associated with them. Therefore, this study tried to address the poor thermal energy management and low energy density of poly (vinylidene fluoride) (PVDF) while maintaining its flexible property using low content of hybrid carbon nanotubes (CNTs–0.05wt%, 0.1wt%) and boron nitride (BN–5wt%, 10wt%) nano-reinforcements. The nanocomposites were developed through solvent mixing and hot compression processes. The dielectric constant increased from 9.1 for the pure PVDF to 42.8 with a low loss of about 0.1 at 100 Hz for PVDF-0.1wt%CNTs-10wt%BN. The thermal stability of the nanocomposites was enhanced by 55°C compared to the pure PVDF. The nanocomposites also showed improved melting and crystallization temperatures. The developed PVDF-CNTs-BN nanocomposites showed significant enhancements in thermal energy management, stability, and dielectric properties. The significantly improved properties are credited to the synergetic effects between CNTs and BN in the PVDF matrix in promoting homogeneous dispersion, thermal barrier, interfacial polarization/bonding, insulative and conductive properties. Therefore, the developed nanomaterials in this study can find advanced applications in the energy-power sector owing to their enhanced performances.

IntroductionThe presence of focal cortical and white matter damage in patients with multiple sclerosis (pwMS) might lead to specific alterations in brain networks that are associated with cognitive impairment. We applied microstructure-weighted connectomes to investigate (i) the relationship between global network metrics and information processing speed in pwMS, and (ii) whether the disruption provoked by focal lesions on global network metrics is associated to patients’ information processing speed.Materials and methodsSixty-eight pwMS and 92 healthy controls (HC) underwent neuropsychological examination and 3T brain MRI including multishell diffusion (dMRI), 3D FLAIR, and MP2RAGE. Whole-brain deterministic tractography and connectometry were performed on dMRI. Connectomes were obtained using the Spherical Mean Technique and were weighted for the intracellular fraction. We identified white matter lesions and cortical lesions on 3D FLAIR and MP2RAGE images, respectively. PwMS were subdivided into cognitively preserved (CPMS) and cognitively impaired (CIMS) using the Symbol Digit Modalities Test (SDMT) z-score at cut-off value of −1.5 standard deviations. Statistical analyses were performed using robust linear models with age, gender, and years of education as covariates, followed by correction for multiple testing.ResultsOut of 68 pwMS, 18 were CIMS and 50 were CPMS. We found significant changes in all global network metrics in pwMS vs HC (p &lt; 0.05), except for modularity. All global network metrics were positively correlated with SDMT, except for modularity which showed an inverse correlation. Cortical, leukocortical, and periventricular lesion volumes significantly influenced the relationship between (i) network density and information processing speed and (ii) modularity and information processing speed in pwMS. Interestingly, this was not the case, when an exploratory analysis was performed in the subgroup of CIMS patients.DiscussionOur study showed that cortical (especially leukocortical) and periventricular lesions affect the relationship between global network metrics and information processing speed in pwMS. Our data also suggest that in CIMS patients increased focal cortical and periventricular damage does not linearly affect the relationship between network properties and SDMT, suggesting that other mechanisms (e.g. disruption of local networks, loss of compensatory processes) might be responsible for the development of processing speed deficits.

BackgroundGastric cancer (GC) is a serious threat to human health. The clinical GC characteristics in China may be impacted by changes in people’s lifestyles and the promotion of early GC (EGC) screening. The present study aims to evaluate the recent trends of GC characteristics in South China and search for hazardous factors limiting the survival time of GC patients.MethodsData on GC patients that were hospitalized in the Department of Digestive Center, the First Affiliated Hospital, Sun Yat-sen University, from 1994 to 2019 were collected and divided into two categories according to the time when the EGC screening began in China: the PRE group (previous 13 years, 1994–2006) and the PAS group (past 13 years, 2007–2019).ResultsWe found that, although the 5-year survival rate increased in the PAS group compared with the PRE group (P &lt; 0.0001), patients with age ≥60 years or Borrmann type IV still had a worse prognosis. In the PAS group, the larger percentages of elderly patients and patients with Borrmann type IV in the lymphatic metastases (N1) group (41.0% vs. 51.1%, P = 0.0014) and stage IV subgroup (20.7% vs. 32.2%, P = 0.016), respectively, when compared with the PRE group, may have contributed to the poor outcome of GC. By comparing the odds ratio (OR) of 5-year overall survival (OS) in the two 13-year periods, female sex and T2 turned into risk factors because of a greater proportion of Borrmann type IV or elderly patients in the PAS group (OR = 0.983, 95% CI = 0.723–1.336 vs. OR = 1.277, 95% CI = 1.028–1.586 and OR = 1.545, 95% CI = 0.499–4.775 vs. OR = 2.227, 95% CI = 1.124–4.271, respectively).ConclusionsDespite the GC epidemiology changes, the overall prognosis of GC patients has improved in South China. However, old age and Borrmann type IV are still the major restrictions affecting the survival of GC patients, a situation which calls for additional attention.

BackgroundHyperglycemia (HG) and prediabetes are rarely sought in pediatric liver (LT) and renal (RT) transplantation, yet their presence indicates a high risk of diabetes and cardiovascular disease. The objectives of our DIABGRAFT study were to retrospectively (rDIABGRAFT) and longitudinally (pDIABGRAFT) characterize HG and (pre)diabetes in a cohort of children with LT or/and RT.MethodsWe retrospectively analyzed risk factors of HG from 195 children with LT from 2012 to 2019 and twenty children with RT from 2005 to 2019 at Cliniques universitaires Saint-Luc. In addition, we prospectively followed four LT and four RT children to evaluate the evolution of their glucose metabolism.ResultsOur rDIABGRAFT study showed that 25% and 35% of LT and RT children respectively presented transient HG and 20% of RT developed diabetes. The occurrence of HG was associated with the use of glucocorticoids and with acute events as graft rejection and infection. In our pDIABGRAFT cohort, biological markers of diabetes were in the normal range for HbA1C, fasting glucose and insulin levels. However, oral glucose tolerance test and glucose sensors showed insulin resistance, impaired glucose tolerance and HG in the post-prandial afternoon period.ConclusionOur study shows that children with LT and RT were more at risk of developing HG when glucocorticoids were required and that HbA1C and fasting glucose lack sensitivity for early detection of glucose intolerance. Also, measurement of glycemia immediately after the transplantation and in postprandial period is key to detect dysglycemia since insulin resistance prevailed in our cohort.ClinicalTrials.gov IDNCT05464043.
Enhanced DQE and sub-pixel resolution by single-event processing in counting hybrid pixel electron detectors: A simulation study
Authors: Zambon P. 
Published: February 2023

Detective quantum efficiency (DQE) is a prominent figure of merit for imaging detectors, and its optimization is of fundamental importance for the efficient use of the experimental apparatus. In this work, I study the potential improvement offered by data processing on a single-event basis in a counting hybrid pixel electron detector (HPD). In particular, I introduce a simple and robust method of single-event processing based on the substitution of the original cluster of pixels with an isotropic Gaussian function. Key features are a better filtering of the noise power spectrum (NPS) and readily allowing for sub-pixel resolution. The performance of the proposed method is compared to other standard techniques such as centroiding and event normalization, in the simulated realistic scenario of 100 keV electrons impinging on a 450 μm-thick silicon sensor with a pixel size of 75 μm, yielding the best results. The DQE can potentially be enhanced over the entire spatial frequency range, increasing from 0.86 to nearly 1 at zero frequency and extending up to 1.40 times the physical Nyquist frequency of the system thanks to the sub-pixel resolution capability.
Can suitability indices predict plant growth in the invaded range? The case of Acacias species
Authors: Silva Carmen P. , López Daniela N. , Naulin Paulette I. , Estay Sergio A. 
Published: February 2023

IntroductionForestry in many parts of the world depends on exotic species, making this industry a source of invasions in some countries. Among others, plantations of the genus Pinus, Eucalyptus, Acacia, Populus, and Pseudotsuga underpin the forestry industry and are a vital component of many countries economies. Among woody plants, the cosmopolitan genus Acacia includes some of the most commonly planted trees worldwide. In order to prevent, manage and control invasive plant species, one of the most used tools is species distribution models. The output of these models can also be used to obtain information about population characteristics, such as spatial abundance patterns or species performance. Although ecological theory suggests a direct link between fitness and suitability, this link is often absent. The reasons behind the lack of this relationship are multiple. Chile is one of the countries where Acacia species, in particular, A. dealbata and A. melanoxylon, have become invaders. MethodsHere, we used climatic and edaphic variables to predict thepotentially suitable habitats for A. dealbata and A. melanoxylon in continental Chile and evaluate if the suitability indices obtained from these models are associated with the observed performance of the trees along the country. ResultsOur models show that variable importance showed significant similarities between the variables that characterize each species’ niche. However, despite the high accuracy of our models, we did not observe an association between suitability and tree growth.DiscussionThis disconnection between suitability and performance can result from multiple causes, from structural limitations, like the lack of biotic interactions in the models, to methodological issues, like the usefulness of the performance metric used. Whatever the scenario, our results suggest that plans to control invasive species should be cautious in assuming this relationship in their design and consider other indicators such as species establishment success.
Childhood family risks and mental health of older adults in China: The moderating effect of age
Authors: Xinzhu Wang 
Published: February 2023

IntroductionChildhood family risks (CFRs) are believed to have long-arm effects on people's mental health. However, it is unclear whether age can alleviate these long-arm effects.AimThis study aimed to explore the relationship between CFRs and the mental health of older adults (mean [M] = 62.10, standard deviation [SD] = 8.02) in China and investigate whether age could moderate this relationship.MethodsThis cross-sectional, survey-based study used data from the Chinese General Social Survey conducted in 2015, and the data of 4,237 respondents were included in the final analysis. Mental health was measured by two items, namely negative and positive emotions. The step-by-step regression procedure and moderation analysis technique were used.ResultsFor older adults in China, CFRs were significantly negatively associated with their mental health (β = −0.046, t = −2.690, p &lt; 0.01), age was positively correlated with their mental health (β = 0.115, t = 7.157, p &lt; 0.01), and age significantly moderated the relationship between CFRs and mental health (β = 0.277, t = 2.172, p &lt; 0.05). As age increases, the correlation between CFRs and mental health decreases, and when age is one SD above the M, CFRs are no longer significantly associated with the mental health level (bsimple = −0.01, t = −0.077, p &gt; 0.05).ConclusionThis study showed that CFRs were negatively associated with the mental health level of older Chinese adults, and age could significantly moderate the association. Therefore, it is essential to take preventive measures in advance to protect people's mental health and teach older adults to use emotion-regulation techniques to weaken the association between CFRs and mental health.
Revisiting fruit and vegetable determinants: Evidence from Latin America
Authors: Silva Andres , Astorga Andrés , Durán-Agüero Samuel , Domper Alejandra 
Published: February 2023

IntroductionIn the past decade, the public health discussion regarding fruit and vegetable (FV) consumption has been dominated by economic and physical accessibility.MethodsUsing an online survey in four Latin American countries, we applied a set of tobit models to compare the determinants of desirable and current consumption of FV levels for satisfied and unsatisfied respondents.ResultsWe found that, even when consuming less than five FV portions a day, most of the respondents were satisfied with their current FV consumption level. Satisfied respondents consumed significantly more FV than unsatisfied ones. In general, the desirable and current consumption of FV levels were associated with different sets of determinants, while years of education were relevant in both cases. Finally, in a hypothetical case where unsatisfied respondents would not face any physical or economic access restrictions, unsatisfied respondents would not reach the goal of five FV portions a day.DiscussionAssuming that physical and economic access improved, this would automatically increase FV to reach the five-a-day recommendation may be inaccurate in some cases. We also need to take mental access into account. We may ask how to improve the desirable level of FVs and then how to close the gap between the current and desirable FV levels.

Published: February 2023

BackgroundSubsidy payments are used to support low-income groups and may improve income distribution and increase social welfare. The food subsidy programs and their long-term effects have been considered as major developmental issues in many developing countries. This review study aimed to examine the effects of subsidies on the food and nutritional status of Iranian people.MethodsEnglish and Persian language databases were searched using related keywords to discover studies on the effects of subsidies on food and nutritional status in Iran. A manual search was also conducted encompassing national and local research projects in Iran. In total, 12 articles were finally included out of an initial total of 70 studies.ResultsSubsidy payment affects many socio-economic variables. In Iran, subsidies are often paid for the basic goods and commodities that are a main part of the consumption patterns of most Iranian people. So, if the basic needs of the people are not well-understood, changes in economic structures may lead to a change in consumption patterns. In addition, physical payments for food may lead to an increase in the consumption of different groups, but cash payments do not necessarily lead to an increase in food intake.ConclusionThe method of payment should be chosen correctly to improve the protection of vulnerable populations. The distribution of targeted subsidies for food security is inevitable due to limited resources available to support vulnerable populations.
Matching ecological transition and food security in the cereal sector: The role of farmers' preferences on production contracts
Authors: Ciliberti Stefano , Frascarelli Angelo , Martino Gaetano 
Published: February 2023

IntroductionUnder an increasing demand from citizen and public institutions, agri-food supply chains are requested to comply with stringent environmental requirements. Moreover, new sources of uncertainty related to pandemic and geo-political turbulences put further pressures on economic agents, calling for proper and resilient governance mechanisms. Under the lens of the Neo Institutional Economics, we focus on production contracts and their clauses which, in turn, perform different functions and contribute to allocate property and decision rights, in the attempt to conciliate sustainability and food security.MethodsIn this framework, contract design assumes a key importance. Thus, we analyze farmers' preferences for different contractual clauses in the cereal sector. A choice experiment is carried out among durum wheat producers in Italy and mixed logit estimations assuming heterogeneous preferences are performed.Results and discussionFindings provide interesting indications, revealing a strong farmers' willingness to adhere production contracts in exchange for price stability and knowledge transfer offered by technical assistance services. However, producers are not available to limit their decisional autonomy in unilateral agreement with buyers and they reveal a certain indifference to costly production techniques aimed to improve environmental sustainability.
the PENGARUH MEDIA TIANG GAWANG PARALON TERHADAP KEMAMPUAN SHOOTING PEMBELAJARAN SEPAK BOLA PADA SISWA KELAS VIII DI SMP NEGERI 4 TOBOALI
Authors: Naviri Sinta 
Published: February 2023

This research was motivated by the average value of students in football shootings was still below the school's KKM criteria of 67. When carrying out shooting techniques, there were still many students whose movements were still wrong. Hence, the direction of the kick was not on target, and there was no use of appropriate learning media to improve student shooting skills. This study aims to determine the effect of paralon's goalpost media on the shooting ability of football learning in class VIII students at SMP Negeri 4 Toboali.
This research was experimental research with a pre-experimental design method. In this study, the design used was a one-group pretest-posttest design. The sample used in this study were all students of class VIII A, totaling 28 students with an average score of shooting learning outcomes under the KKM criteria of 67. The data collection technique in this study used the football shooting ability test. The data analysis technique in this study used normality, homogeneity, and hypothesis testing.
Based on the results of statistical tests using the t-test formula between the initial test (pretest) and the final test (posttest), the result was that the t-count value was 11.208, while with a significant level of 0.05, the t-table value was 1.703. It turned out that the value of the t-count was more significant than the value of the t-table (t-count 11.208 > t-table 1.703), so it could be concluded that Ho was rejected, and Ha was accepted. The conclusion is "There is a significant influence of the media of paralon's goalposts on the shooting ability of football learning in class VIII SMP Negeri 4 Toboali".
