BACKGROUND: Type 2 diabetes is a major public health concern in the United States and worldwide. The dietary inflammatory index (DII) and the energy-adjusted DII (E-DII) are tools that assess dietary inflammation. Previous evidence suggests that obesity can modify the association between inflammation and disease. OBJECTIVE: The aim of this study was to evaluate the association between the DII/E-DII and incident diabetes in self-identified Hispanic women from the Womens Health Initiative (WHI). The secondary aim was to evaluate whether obesity modifies the association between the DII/E-DII scores and incident diabetes. DESIGN: Participants were from the WHI Observational Study and the Clinical Trial Components (except women from the treatment arm in the Dietary Modification Trial) conducted among postmenopausal women in the United States. DII/E-DII scores were calculated from a self-administered food frequency questionnaire at baseline that included 122 food items, of which 12 are representative of Hispanic eating patterns. PARTICIPANTS/SETTINGS: Participants included 3,849 postmenopausal women who self-identified as Hispanic that were recruited for the WHI from 1993 to 1998 at 40 US clinical centers. MAIN OUTCOME MEASURES: The outcome was incident diabetes. STATISTICAL ANALYSIS PERFORMED: Cox regression models were used to assess the association between DII/E-DII and incident diabetes. Models were adjusted for age at baseline, lifestyle-related risk factors, known type 2 diabetes mellitus (T2DM) risk factors, and neighborhood socioeconomic status. Interaction was tested between the DII/E-DII scores and obesity. RESULTS: The incidence of diabetes was 13.1% after a median follow-up of 13 years. Higher E-DII scores were associated with a higher risk of incident diabetes (hazard ratio [HR], 1.09; 95% confidence interval [CI], 1.04-1.14). There was no interaction between E-DII scores and obesity (P = 0.73). CONCLUSIONS: Pro-inflammatory diets, as measured by higher E-DII scores, were associated with a higher risk of incident diabetes. Future research is needed for understanding how the inflammatory potential of diets can be decreased.

BACKGROUND/OBJECTIVES: School meals are an important source of nutrition for children and have been found to help mitigate food insecurity. This study evaluated the association between food insecurity and school meal participation and whether parental perceptions about school meals differ by food security status. METHODS: In May 2022, 1110 Californian parents of K-12 students shared their perceptions about school meals, including meal quality, healthiness, stigma, and benefits, as well as their childs participation in school meals, in an online survey. Household food security was determined using the USDA 6-item module. Logistic and Poisson regression models were used for analysis. RESULTS: The prevalence of household food insecurity was 56.2% (69.6% in households of students eligible for free meals, 55.9% in reduced-price, and 38.3% in non-eligible). Many of the reported benefits of school meals (saving families money and time) were equally highly endorsed by parents with and without food insecurity (p > 0.05). Parents reporting food insecurity had less favorable perceptions of school meals and perceived more stigma (p < 0.05). Food insecurity was positively associated with breakfast participation, especially among elementary school students and students not eligible for free or reduced-price meals (FRPMs) (p < 0.05). CONCLUSIONS: Food insecurity is prevalent among California families with school-age children, even in families not eligible for federal FRPMs. Food-insecure households have more negative perceptions of school meals and experience more stigma, though they also report higher breakfast participation. Improving school meal quality and appeal, ensuring parents are familiar with meal quality and healthfulness, and reducing stigma may ease food insecurity while improving childrens health.

Parental perceptions of school meals can affect student participation and overall support for school meal policies. Little is known about parental school meal perceptions under universal free school meals (UFSM) policies. We assessed California parents perceptions of school meals during the COVID-19 emergency response with federally funded UFSM and whether perceptions differed by race/ethnicity. Among 1110 California parents of K-12 students, most reported school meals benefit their families, saving them money (81.6%), time (79.2%), and stress (75.0%). Few reported that their child would be embarrassed to eat school meals (11.7%), but more parents of White students than Hispanic students reported this. Many parents reported that their child likes to eat lunch to be with friends (64.7%); about half felt their child has enough time to eat (54.2%). Fewer parents perceived school lunches to be of good quality (36.9%), tasty (39.6%), or healthy (44.0%). Parents of Hispanic and Asian students had less favorable perceptions of school meal quality, taste, and healthfulness than parents of White students. Parents report that school meals benefit their families, but policy efforts are needed to ensure schools have the resources needed to address cultural appropriateness. Schools should address parental perceptions of meals to optimize participation, nutrition security, and health.

The responses of the N-alkyl diamine groups to variations in pH affect their conformations and surface activities, making them relevant to applications relying on interfacial interactions, such as controlled emulsification and mineral flotation. An in-depth understanding of interfacial self-assembly is crucial. Herein, a molecular-level study was performed to investigate the adsorption and self-assembly of N-dodecylpropane-1,3-diamine (DPDA) at the air–water (A/W) interface using sum frequency generation (SFG) spectroscopy and molecular dynamics (MD) simulations. The SFG spectra of DPDA, acquired under three pH conditions, suggest that the protonation of the DPDA diamine group influences the alkyl chain arrangement at a varying degree at the A/W interface. Analysis of the di-cationic DPDA SFG spectrum at a low pH showed fewer gauche defects at low concentration, as indicated by the relatively higher intensity ratio (ICH3SS/ICH2SS) of 18.1 ± 0.6. The density profiles from MD simulations at different surface areas per molecule and pH conditions, showing varying degrees of packing, support the observation of gauche defects in SFG. With MD simulation, the radial distribution factor for di-cationic species has the highest probability of forming hydrogen bonds compared to mono-cationic and non-ionic species. These g(r) probability results conform with observations obtained from SFG spectroscopy, where we observed a strong hydrogen bond interaction at low pH conditions with di-cationic species, forming tetrahedrally arranged water molecules at the A/W interface. Overall, comprehensive insights will facilitate the visualization of alkyl diamines and their potential derivatives at the A/W interface, enabling a better understanding of their behavior across various applications.

BackgroundTo evaluate the association between the dietary inflammatory index (DII®) and incident cardiovascular disease (CVD) in Hispanic women from the Women's Health Initiative (WHI), and to determine if body mass index (BMI) interacted with the DII scores.MethodsSecondary analysis of baseline dietary data and long-term CVD outcomes among 3,469 postmenopausal women who self-identified as Hispanic enrolled in WHI. DII scores were calculated from self-administered food frequency questionnaires. The CVD outcomes included coronary heart disease (CHD) and stroke. Stratified Cox regression models were used to assess the relationship between DII scores and CVD in women with and without obesity. Models were adjusted for age, lifestyle risk factors, known risk factors, and neighborhood socioeconomic status.ResultsThe incidence of CHD was 3.4 and 2.8% for stroke after a median follow-up of 12.9 years. None of the DIIs were associated with CVD risk in this sample of Hispanic women. BMI interacted with the DII (p

ObjectivesThe Swiss Cohort of Healthcare Professionals and Informal Caregivers (SCOHPICA) was created to study the career trajectories, retention intentions, and wellbeing of healthcare professionals (HCPs), addressing challenges such as staff turnover, low job satisfaction and burnout.MethodsSCOHPICA is a prospective open cohort. An electronic questionnaire was used to collect data from HCPs across multiple healthcare settings in Switzerland, encompassing the intention to stay in the profession, wellbeing, and various organizational, psychosocial, occupational and sociodemographic determinants.ResultsThe first (2022) baseline sample included 1707 HCPs from over 20 professions. Notably, 13% did not intend to stay in their profession, with intermediate caregivers (24%), registered nurses (17%) and pharmacists (17%) reporting the highest rates. Pharmacists scored lowest in wellbeing. Across determinants, pharmacists, physicians, and registered nurses reported worse scores for workload and work-life balance. Nursing professions had lower scores in various determinants, including influence at work, staffing and resource adequacy, and possibilities for development.ConclusionSCOHPICA will provide critical insights on HCPs’ work conditions and experiences, supporting health workforce monitoring and management, and informing policy-making to ensure high-quality healthcare delivery.

BackgroundHispanics are a heterogeneous population with differences in the prevalence of cardiovascular disease (CVD) and its related risk factors among ethnic sub-groups. This study evaluated the association of genetic admixture and CVD in self-identified Hispanic women from the Women's Health Initiative (WHI).MethodsData came from the WHI Observational Study and the Clinical Trial Components conducted among postmenopausal women. The CVD outcomes included coronary heart disease (CHD) and stroke. The proportions of European (EUR), sub-Saharan African (AFR), and Amerindian (AMI) admixture were estimated using 92 ancestry-informative markers. Cox regression models were used to assess the relationship between genetic admixture and CVD adjusting for age, lifestyle risk factors, known risk factors, and neighborhood socioeconomic status.ResultsAmong 5195 participants EUR ancestry was associated with a lower CHD risk after adjusting for age (HR 0.41, p = 0.02), and in the fully adjusted model (HR 0.40, p = 0.03). AFR ancestry was associated with a higher CHD risk after adjusting for age (HR 2.91, p = 0.03), but it only showed a trend in in the fully adjusted model (HR 2.46, p = 0.10). AMI ancestry was not statistically significantly associated with CHD and none of the genetic admixture proportions were statistically significantly associated with stroke (p > 0.05).ConclusionEUR ancestry was associated with a lower risk of CHD in Hispanic women. This highlights the need to account for genetic admixture in future CVD studies to consider different heritage groups to understand the role that genetic, neighborhood socioeconomic status, and environmental factors contribute to CVD health disparities in Hispanic women.

School meals play a major role in supporting children's diets and food security, and policies for universal school meals (USM) have the potential to contribute to positive child health outcomes. During the COVID-19 pandemic, schools provided free school meals to all students in the United States, but this national USM policy ended in school year (SY) 2022-2023; however, a few states have adopted policies to continue USM statewide for SY 2022-2023. Research examining the challenges and strategies for successful continuation of USM is essential, along with studying pandemic-related challenges that are likely to persist in schools. Therefore, we conducted a study in Maine (with a USM policy) to evaluate the impact of COVID-19 and the concurrent implementation of USM, as well as examine differences in implementation by school characteristics, throughout the state. A total of n = 43 school food authorities (SFAs) throughout Maine completed surveys. SFAs reported multiple benefits of USM including increased school meal participation; reductions in the perceived stigma for students from lower-income households and their families; and no longer experiencing unpaid meal charges and debt. SFAs also experienced challenges due to the COVID-19 pandemic, particularly regarding costs. When considering future challenges, most respondents were concerned with obtaining income information from families, product and ingredient availability, and the costs/financial sustainability of the school meal programs. Overall, USM may have multiple important benefits for students and schools, and other states should consider implementation of a USM policy.

Universal school meals (USM) have the potential to increase access to healthy food for millions of U.S. students. This study evaluated school food authorities’ (SFA) perspectives of federal USM in response to COVID-19 (school year (SY) 2021−22) and California’s upcoming USM policy in the SY 2022−23. In February 2022, all SFAs in California (n = 1116) were invited to complete an online survey. Descriptive statistics and logistic regression examining differences by school demographic characteristics were used. Five hundred and eighty-one SFAs completed the survey; 63% of them first implemented USM during the COVID-19 pandemic. Reported benefits included increased student meal participation (79.2%) and reduced stigma (39.7%). Top challenges included staffing (76.9%) and meal packaging/solid waste (67.4%). Nearly all SFAs reported pandemic-related challenges procuring the necessary types (88.9%) and amounts of foods (85.9%), and non-food supplies/equipment (82.6%). Over 40% reported that federal reimbursements were insufficient to cover costs. SFAs with

Gamification approaches to learning use game-inspired design elements to improve learning. Given manifold design options to implement gamification in virtual environments, an important but underexplored research area is how the composition of gamification elements affects learning. To advance research in this area, we systematically identified key design elements that have shown promise in leading to positive learning results. We then conducted an experiment in which we varied gamification intensity in web-based virtual training environments for a procedural industrial task. In total, 355 participants were divided into a baseline group without gamification, a basic, and an advanced gamification group. Analysis of participants' learning included learning outcomes (time-to-completion and number of mistakes), affective learning factors (motivation, self-efficacy, and satisfaction), learning system usability, and perceived cognitive load throughout the learning process. The results did not show any statistically significant differences between the lower and higher levels of gamification intensity. Conversely, we found that participants' computer gaming habits and technical equipment (display size and computer pointing device) significantly influenced learning.

Possessing awareness about the human body is important for the maintenance of good health. To increase such awareness in children's daily lives, we developed and implemented a two-hour activity session for a group of nine Cub Scouts. Three graduate students, one undergraduate student, and one high school student assisted faculty during this session. The children were given a presentation about the human body using an Anatomage Table and models of the heart, lungs, liver, kidney, muscle, and ear. The Cub Scouts were given a brief quiz before and after the session in order to evaluate the impact of the intervention on students' knowledge. The post-test score was 8% higher than the pre-test score (p<0.05), suggesting that the introduction to the human body was helpful in enhancing Cub Scouts' learning. This project also allowed high school, undergraduate, and graduate students to communicate anatomy with young children at their level.
