Integrating bioinspired design and additive manufacturing into engineering education fosters innovation to meet the growing demand for accessible, personalized assistive technologies. This paper presents the outcomes of an international course, “3D Prosthetics and Orthotics”, offered to undergraduate students in the Biomimetic program at Westfälische Hochschule (Germany), in collaboration with the 3D Orthotics and Prosthetics Laboratory at the Federal University of São Paulo—UNIFESP (Brazil). The course combined theoretical and hands-on modules covering digital modeling (CAD), simulation (CAE), and fabrication (CAM), enabling students to develop bioinspired assistive devices through a Project-based learning approach. Working in interdisciplinary teams, students addressed real-world rehabilitation challenges by translating biological mechanisms into engineered solutions using additive manufacturing. Resulting prototypes included a hand prosthesis based on the Fin Ray effect, a modular finger prosthesis inspired by tendon–muscle antagonism, and a cervical orthosis designed based on stingray morphology. Each device was digitally modeled, mechanically analyzed, and physically fabricated using open-source and low-cost methods. This initiative illustrates how biomimetic mechanisms and design can be integrated into education to generate functional outcomes and socially impactful health technologies. Grounded in the Mao3D open-source methodology, this experience demonstrates the value of combining nature-inspired principles, digital fabrication, Design Thinking, and international collaboration to advance inclusive, low-cost innovations in assistive technology.

The Social Housing units in the “Minha Casa Minha Vida Program” (PMCMV), launched in 2009, aimed to reduce the housing deficit in Brazil. However, they resulted in standardized units of low architectural quality, which were disconnected from the diverse Brazilian contexts. These housing units exhibit low resilience and lack the technical assistance required for renovations, leading residents to undertake self-built modifications. Such interventions, often inadequate, negatively impact environmental comfort and structural safety. The Federal Law on Technical Assistance for Social Housing (TASH) No. 11.888 advanced the provision of technical assistance but still faces challenges regarding its implementation due to significant demand. This article is part of a master’s research project linked to the [CASA RESILIENTE] initiative of the [MORA] Research Group on Housing and, aims to identify and analyze relevant studies, contributing to the analysis and improvement of the pilot platform “[REFORMA] na palma da mão” (“Handy Home Improvements”). The methodology includes a literature review of TASH, resilience in the built environment, social practices in Social Housing (SH), and post-occupancy evaluation (POE), as well as a study of artifacts similar to the proposed platform. The results highlight the importance of POE, the urgency of implementing TASH, and the need to deepen studies on social practices in SH to provide guidelines for more resilient renovations.

The U.S. Federal STEM Strategic Plan released in 2018 charged federal agencies to operate with transparency and accountability regarding the impact of STEM programming on participant outcomes. This study’s purpose is to share a robust and iterative design-based research validation study for a middle school (U.S. grades 6–8; ages 11–14 years old) Student STEM Outcomes Survey. Our team partnered with NASA to develop an instrument to study the impact of participation in NASA Office of STEM Education’s (OSTEM) engagement programming on middle school student affective outcomes. Overall, this study produced strong validity evidence for each construct (STEM Identity, STEM Self-Efficacy, STEM Interest, 21st century skills) of the Student STEM Outcomes Survey. Qualitative field testing results from subject matter experts and middle grade students related to content, response processes, and consequences of testing validity evidence provided support for data-informed item wording modifications. Rasch psychometric results assisted in meaningfully paring back items to ultimately result in parsimonious and psychometrically sound survey sections based on internal structure and response processes findings. Suggestions for using the newly developed and validated Student STEM Outcomes Survey are provided. Full article

Background: Childhood obesity is a pressing global public health challenge, marked by significant disparities in prevalence and management across countries. Japan and the United States offer contrasting approaches to addressing this issue, presenting a valuable opportunity for comparative analysis. Objective: This review examines the effectiveness of public health policies, cultural dietary habits, and lifestyle factors in combating childhood obesity in Japan and the United States. It aims to identify actionable insights to inform global strategies for obesity prevention. Results: Japan exhibits one of the lowest childhood obesity rates globally, attributed to prevention-focused policies such as the food education program, stringent school lunch standards, and culturally ingrained healthy eating practices. These efforts are complemented by active lifestyle promotion through urban planning and school-based physical education programs. In contrast, the United States faces higher obesity rates due to systemic challenges, including socioeconomic disparities, reliance on processed foods, sedentary lifestyles, and inconsistent implementation of federal programs like the National School Lunch Program (NSLP) and Supplemental Nutrition Assistance Program Education (SNAP-Ed). Conclusions: This review highlights Japan’s success in aligning public health initiatives with cultural norms to achieve sustainable outcomes. In the United States, systemic barriers and cultural disconnects hinder obesity prevention efforts. Recommendations include adopting integrated, prevention-focused policies, addressing socioeconomic inequities, redesigning urban environments to promote active living, and fostering global collaboration. This comparative analysis underscores the importance of culturally tailored, multidimensional strategies for addressing childhood obesity and improving public health outcomes worldwide. Full article

Coal is a major source of fuel in many countries, but its mining and use increase the impacts on human and environmental health. Given the wide variation in coal use by nation, we focused on one—the United States. Specifically, we examined the public health, community, and demographic characteristics of 130 U.S. counties with underground and/or surface coal mines that exemplify a land use that leads to a combination of natural and anthropogenic risks. We compared these 130 to other U.S. counties, finding that the coal counties had poorer health outcomes and behaviors, fewer community assets, lower socioeconomic status, and higher population losses compared to the remaining counties in their host states and other U.S. counties. Next, we looked for differences within the 130 coal counties. Counties with the most coal mines and production had the worst outcomes, especially when located in rural areas. We then examined federal programs to assist these coal communities, observing that the largest federal government programs appear to be sending more resources to the most distressed coal counties compared to the less distressed ones. The daunting challenge for the most heavily coal-dependent counties, their state governments, and federal government supporters is to jointly develop plans that are realistic and affordable, take advantage of local natural and human resources, and offer a path to sustainable existence. If the efforts do not succeed, these places run the risk of becoming politically invisible and their populations are likely to empty out. Full article

Pharmacists are often the first point of contact for healthcare advice in rural communities, where access to healthcare is limited. Tobacco cessation rates improve with counseling from a pharmacist, and in many states, pharmacists can now prescribe medications for quitting. This study aimed to explore smoking behavior and cessation motivations among patients at a Federally Qualified Health Center (FQHC) clinic in rural Wyoming, estimate the prevalence of tobacco-related interventions by clinic staff, and assess patients’ interest in engaging in pharmacist-led cessation programs. A cross-sectional survey was administered over three months to clinic patients who self-identified as current tobacco users. Survey items assessed sociodemographics, tobacco use and vaping behaviors, previous cessation advice from pharmacists, and interest in pharmacist-led support for quitting. Of 63 respondents, 57 (90.5%) reported current tobacco use. Most were ready to quit within the next month (43.9%) or the next six months (33.3%), and 26.3% had previously received advice about quitting from a pharmacist. Most (59.6%) expressed interest in establishing care with a pharmacist for cessation support, and 45.3% requested to be contacted by a pharmacist for assistance with quitting. Interest did not differ by gender or age. The results indicate that rural patients are interested in engaging with pharmacists for quitting. Further research is needed to determine how pharmacy-led programs can complement existing healthcare resources to improve access to cessation support in underserved areas. Full article

Promoting child well-being and development requires a multidimensional approach, including the right to adequate food practices. Socially vulnerable children are more exposed to adverse experiences, such as inadequate food consumption due to poverty. In this context, home-visiting programs are an important strategy for nutritional and health care education to provide relevant guidelines. This study describes breastfeeding and food consumption of children aged 0 to 24 months assisted by the Happy Child Program (Programa Criança Feliz—PCF) and aimed to investigate their association with socioeconomic factors and adherence to the program. This is an observational study, with a cross-sectional design, carried out with children assisted by the PCF in the Federal District, Brazil. Multivariate analysis was performed to identify sociodemographic and income factors, and household visits characteristics associated with breastfeeding, dietary diversity, and the consumption of ultra-processed food. A total of 301 children were assessed, 51.16% of whom were female. In 58.99% of households, the reference person was the mother; 86.20% were unemployed, and 27.08% had a low education degree. About 62.65% of beneficiaries lived on up to USD 200.00 per month and the majority faced food insecurity. The child’s age, and the mother’s current work situation were independently associated with the current breastfeeding situation, especially higher among women who did not work (p = 0.015). The minimum dietary diversity among children over 6 months old was 62.21% and presented a positive association with adherence to the program (p = 0.005). On the other hand, the consumption of ultra-processed foods was 77.21% and was associated with a longer follow-up time within the program (p = 0.047). The associations observed revealed the need to integrate family food choices and nutritional education into public policies for early childhood. Full article

Background/Objectives: This paper examines hunger over time to analyze how food insecurity is impacted by reduced income, including household funding from the government. Federal policies and community-based programs have the ability to prevent increases in food insecurity, particularly for populations that have risk factors, such as households with children; single-parent households; low-income households, especially those in rural areas; Black and Hispanic households; and, households experiencing economic hardships. Methods: This study is bas ed on a cross-sectional survey that was administered in 2018 and 2019 to food pantry clients, an already food insecure population accessing resources, in Eastern Massachusetts. Baseline surveys were matched with a 3-month follow-up survey (n = 308) and multinomial logistic mixed effect models were used to analyze the association between change in household hunger and change in household income. Results: This study found that participants who experienced decreased income compared to no income change from baseline to follow-up had 2.16 times the odds (95% CI: 1.05, 4.46) of experiencing increased household hunger compared to no change in hunger from baseline to follow-up, after adjusting for all other covariates. Conclusions: Food insecurity in the United States remained stable during the beginning of COVID-19, despite prevalence of reduced household income. The expanded government benefits that were implemented early in the pandemic contributed to total household income, which prevented increased food insecurity. Increased food insecurity after the removal of benefits starting in 2022 indicates the importance of continuing support established during times when consistent income is compromised to prevent a delayed rise in food insecurity.

Background/Objectives: Food insecurity (FI) is defined as the lack of consistent access to enough food for an active and healthy life. FI affects over 30 million Americans and is associated with poor clinical outcomes and impaired quality of life and drives significant health inequities. Despite the rising prevalence of FI and the federal focus on improving access to healthy food, there is a paucity of research on FI in patients with inflammatory bowel disease (IBD). Therefore, the goal of this study was to define FI in a cohort of IBD patients and determine whether FI was associated with changes in dietary patterns, including specifically an increase in ultra-processed food (UPF) consumption in this high-risk patient population. Methods: This was a single-center, retrospective cohort study of patients with a diagnosis of IBD who were 18 years of age or older and who were seen in a nutrition focused clinic. Patients were screened for FI using the Hunger Vital Sign™, a 2-question validated FI screening tool and underwent a 24-h dietary recall. The degree of food processing was assessed using the NOVA Food Classification System. Results: Among 128 patients with IBD, we observed that FI is increasingly prevalent, with 45% of patients reporting difficulty with sufficient grocery access at least “sometimes” in the last 12 months and 10% reporting decreased food access “often” in the prior year. In addition, the patients at high-risk for FI were significantly more likely to eat NOVA 4 UPFs (54% vs. 27%, p = 0.001) and were significantly less likely to eat NOVA 1 unprocessed foods (32% vs. 61%, p = 0.001) as compared to those not at risk for FI. Finally, only a small percentage of those at highest risk for FI were enrolled in a federal food assistance program for grocery support. Conclusions: The prevalence of FI is increasing in patients with IBD and is associated with reduced dietary quality. Full article

Background/Objectives: Puerto Rican households often face elevated rates of food insecurity. Frequently, households experiencing food insecurity turn to federal and emergency nutrition assistance for urgent or prolonged aid. This study analyzes factors influencing food insecurity and food assistance program involvement among Puerto Ricans in Holyoke, Massachusetts, amidst the COVID-19 pandemic. Methods: Using a combination of community-based participatory recruitment, purposive sampling, and web-based tools, we collected 284 survey responses. Our paper employed Pearson’s chi-square, logistic regression, and hierarchical linear models to assess relationships between demographic and household attributes and food access outcomes. Results: Variables such as having children in the household and age significantly influenced food relief participation and food insecurity outcomes. Puerto Rican heritage and low educational attainment were strong predictors of obtaining federal food aid. Low-income participants disproportionately faced food shortages and depended on emergency food initiatives. Our findings indicate that demographic and household factors significantly influence food insecurity and accessibility. Conclusions: Our study demonstrates that the pandemic made it challenging for households to obtain consistent, safe, and affordable nourishment. The impacts were unequally spread; hence, Puerto Rican communities and low-income groups were most affected. Full article

This paper used pavement condition data collected by the Federal Highway Administration (FHWA) between 2001 and 2006 aggregated by U.S. states to identify macroscopic factors affecting pavement roughness in time and space. To account for prior pavement conditions and preservation expenditure over time, time autocorrelation parameters were introduced in a spatial modeling scheme that accounted for spatial autocorrelation and heterogeneity. The proposed framework accommodates data aggregation in network-level pavement deterioration models. Because pavement roughness across different roadway classes is anticipated to be affected by different explanatory parameters, separate time–space models are estimated for nine roadway classes (rural interstate roads, rural collectors, urban minor arterials, urban principal arterials, and other freeways). The best model specifications revealed that different time–space models were appropriate for pavement performance modeling across the different roadway classes. Factors that were found to affect state-level pavement roughness in time and space included preservation expenditure, predominant soil type, and predominant climatic conditions. The results have the potential to assist governmental agencies in planning effectively for pavement preservation programs at a macroscopic level. Full article

The 63.6 million Hispanic individuals living in the United States constitute the largest ethnic or racial minority group in the country. Hispanic/Latino households report a high prevalence of food insecurity, and often, food-insecure individuals cope by turning to emergency and federal food assistance programs for immediate or long-term assistance. This paper focuses on Hialeah, Florida, a predominantly Hispanic/Latino city in Miami-Dade County. It examines which demographic factors influence participation in food assistance programs and the occurrences of periods of disrupted food access. This study examines two questions: (1) What factors are associated with participation in food assistance programs? (2) To what extent did study participants use food assistance programs before and during the COVID-19 pandemic? We conducted a survey and collected 684 responses from April to August 2022. We gathered data on participants’ identities, household attributes, and their usage of federal and emergency food assistance programs. We used Pearson’s chi-square tests to identify significant associations between food assistance usage, food access, and respondents’ demographic characteristics. We also used binary logistic regression models to assess probabilities. The findings of this research are significant, indicating that the COVID-19 pandemic exacerbated food access challenges in Hispanic/Latino households in 2022. The data also revealed that low-income households, respondents below the age of 40, individuals born in the United States, those with low educational attainment, and those living in multifamily households had the highest likelihood of using food assistance programs. Single- and non-single-parent households, employment status, languages spoken at home, and number of children in the household were also statistically significant factors in predicting food assistance usage. This research provides valuable insights into how individuals in a city responded to the pandemic by utilizing food assistance programs. Full article

Given the lack of attention on adolescent food insecurity, the primary objective of this study was to assess the association of household participation in federal food assistance programs with food security status among adolescents in Baltimore during the COVID-19 pandemic. Adolescents, ages 14–19 years, were invited to participate in two online surveys. The baseline was implemented between October 2020 and January 2021, while the follow-up took place one year later from November 2021 to January 2022 after schools had re-opened. We then matched survey participants with household participation in food nutrition assistance programs using data obtained from the Maryland Department of Social Services. We used logistic regression to examine the association between food assistance program participation status and food insecurity. Additionally, to examine whether the impact of program participation on food insecurity changed between the baseline survey and one year later at follow-up when schools re-opened, a difference-in-differences analysis was conducted. The results showed no significant associations between adolescent food security and participation in any of the federal nutrition assistance programs. Increased attention on how best to improve adolescent food security in low-income households that can respond to the unique needs of adolescents is clearly warranted. Full article

Numerous organizations employ decision-making processes to support operational activities; however, decisions and mistakes can significantly impact Market Performance (MP) due to the oversight of organizational architecture and the environment. This becomes particularly critical in the realm of strategic management, where improper practices and a lack of management understanding can lead to substantial losses. Hence, a systemic investigation was undertaken to explore the repercussions of not adopting such an approach concerning organizational architecture and the environment. Employing a quantitative analysis via hierarchical regression involving Confirmatory Factor Analysis and Ordinary Least Squares, using data gathered from a survey encompassing 134 collaborators from Brazilian Federal Universities. The findings show that the organizational environment positively impacts decision-making, leading to better MP. Additionally, organizational architecture partially mediates the link between the organizational environment and decision-making. Remarkably, national literature lacked research combining Student Assistance Program (PNAES) actions with MP improvement to assess Brazilian Federal Universities’ effectiveness. Full article

Understanding the association between food security status (FSS) and diet quality in children is crucial. This study investigated regional variability in FSS, participation in the federal nutrition assistance program (FNAP), and diet quality among US children. National Health and Nutrition Examination Survey (NHANES) data from 2013 to 2016 were analyzed. The association between FSS, FNAP participation, and diet quality (Healthy Eating Index—HEI-2015) was assessed using multiple linear/logistic regression models. The sample included 6403 children (mean age: 7.5 years; 51% male; 33% Hispanic). Within the sample, 13% reported child food insecurity, and 30% reported household food insecurity. Additionally, 90% participated in the FNAP, and 88% were enrolled in school lunch programs. Children in urban areas were significantly more likely to report household food insecurity than those in rural areas (29.15% vs. 19.10%). The overall HEI-2015 score was 48.2. The associations between child/household FSS and FNAP participation as well as between child/household FSS and diet quality did not differ by urban/rural residence status, irrespective of the children’s age groups. There is a need for improvement in children’s diet quality, regardless of age or urban/rural residence. The findings suggest that improving children’s diets requires broader action as well as the prioritizing of children in urban areas experiencing food insecurity in future dietary interventions.
