Background/Objectives: Routine preventive care, including physical examinations, mammography, and cervical cancer screening, is critical for long-term health maintenance and recurrence surveillance among breast cancer survivors. Community-based organizations (CBOs) may play a key role in supporting adherence to these services through education, navigation, and survivorship care planning. Methods: A secondary analysis was conducted using data from N = 777 breast cancer survivors who contacted a national cancer-focused CBO for resources, including no-cost patient navigation. Preventive care adherence was measured via a composite index based on self-reported receipt of physical exams, mammograms, and Pap smears at guideline-recommended intervals. Patient-reported outcomes were assessed 30 days post-contact, including Survivorship Care Planning (SCP) receipt and quality of life (QoL). Results: Adherence to all three guideline-based screenings was reported by 66% of BCS, 29% adhered to two, and 6% to one or fewer. Physical exams had the highest adherence rate (97%), followed by mammograms (88%) and Pap smears (73%). Bivariate analyses showed higher adherence among younger survivors (t = 4.59, df = 711, p < 0.001), non-white survivors (t = −3.27, df = 267, p < 0.001), those in partnered relationships (t = 1.76, df = 54, p < 0.05), and individuals with better QoL (r = −0.09, p < 0.01). Receipt of SCP components was associated with a trend toward improved adherence: 56% received a care summary, 64% received follow-up instructions, and 45% received written materials (r = 0.05, p < 0.10). In multivariable regression adjusting for partnership status and SCP receipt, younger age (B = 1.13, p < 0.001), non-white race/ethnicity (B = 1.00, p < 0.01), and higher QoL scores (B = 0.09, p < 0.05) were significantly associated with greater adherence. Conclusions: Engagement with a CBO was associated with high levels of adherence to preventive care among breast cancer survivors—especially those who were younger, non-white, and with better QoL. SCP, particularly when delivered in written form with follow-up instructions, may support improved adherence. These findings highlight the value of CBO-led survivorship support in promoting long-term health maintenance for breast cancer survivors. Full article

Obesity is a global health challenge marked by substantial inter-individual differences in responses to dietary and lifestyle interventions. Traditional weight loss strategies often overlook critical biological variations in genetics, metabolic profiles, and gut microbiota composition, contributing to poor adherence and variable outcomes. Our primary aim is to identify key biological and behavioral effectors relevant to precision medicine for weight control, with a particular focus on nutrition, while also discussing their current and potential integration into digital health platforms. Thus, this review aligns more closely with the identification of influential factors within precision medicine (e.g., genetic, metabolic, and microbiome factors) but also explores how these factors are currently integrated into digital health tools. We synthesize recent advances in nutrigenomics, nutritional metabolomics, and microbiome-informed nutrition, highlighting how tailored dietary strategies—such as high-protein, low-glycemic, polyphenol-enriched, and fiber-based diets—can be aligned with specific genetic variants (e.g., FTO and MC4R), metabolic phenotypes (e.g., insulin resistance), and gut microbiota profiles (e.g., Akkermansia muciniphila abundance, SCFA production). In parallel, digital health tools—including mobile health applications, wearable devices, and AI-supported platforms—enhance self-monitoring, adherence, and dynamic feedback in real-world settings. Mechanistic pathways such as gut–brain axis regulation, microbial fermentation, gene–diet interactions, and anti-inflammatory responses are explored to explain inter-individual differences in dietary outcomes. However, challenges such as cost, accessibility, and patient motivation remain and should be addressed to ensure the effective implementation of these integrated strategies in real-world settings. Collectively, these insights underscore the pivotal role of precision nutrition as a cornerstone for personalized, scalable, and sustainable obesity interventions. Full article

Background: The importance of understanding dietary habits during working hours is becoming increasingly evident. As demonstrated, dietary habits have been shown to exert a considerable influence on the productivity of workers and the creation of a healthier workplace. Objective: The aim of this study is to assess the nutritional quality and self-perception of lunches consumed by workers in Piedmont (Italy). Methods: A questionnaire, supported by the EasyDietWeb 4.3.0 software, was used to assess the macronutrient composition of the meals and to evaluate adherence to the “Healthy Eating Plate” (HEP) guidelines. The basal metabolic rate and total daily energy expenditure of the subjects were calculated. Results: The survey results, which included 189 participants, revealed that a notable proportion of the respondents consumed homemade meals at their place of work. The majority of meals reported by the participants did not align with the HEP composition due to the absence of one or more components, especially vegetables. The participants’ perceptions of meal balance frequently diverged from the actual nutritional quality of the meals. Finally, overweight participants exhibited a higher risk of reporting diseases (OR = 4.4, 95% CI = 1.6–12.0). Conclusions: This study provides insight into the dietary habits of a specific group of workers regarding their lunch consumption. This underscores the significance of enhancing public awareness regarding dietary choices and nutritional intakes, as adhering to proper dietary routines is paramount for preserving a state of well-being and sustaining a healthy lifestyle.

The growing popularity of Personal Light Electric Vehicles (PLEVs), such as e-scooters, has revolutionized urban mobility by offering compact, cost-effective, and environmentally friendly transportation solutions. However, safety concerns, including inadequate infrastructure, poor protective measures, and high accident rates, remain critical challenges. This paper presents the design and development of an innovative self-balancing microvehicle under the H2020 LEONARDO project, which aims to address these challenges through advanced engineering and user-centric design. The vehicle combines features of monowheels and e-scooters, integrating cutting-edge technologies to enhance safety, stability, and usability. The design adheres to European regulations, including Germany’s eKFV standards, and incorporates user preferences identified through representative online surveys of 1500 PLEV users. These preferences include improved handling on uneven surfaces, enhanced signaling capabilities, and reduced instability during maneuvers. The prototype features a lightweight composite structure reinforced with carbon fibers, a high-torque motorized front wheel, and multiple speed modes tailored to different conditions, such as travel in pedestrian areas, use by novice riders, and advanced users. Braking tests demonstrate deceleration values of up to 3.5 m/s², comparable to PLEV market standards and exceeding regulatory minimums, while smooth acceleration ramps ensure rider stability and safety. Additional features, such as identification plates and weight-dependent motor control, enhance compliance with local traffic rules and prevent misuse. The vehicle’s design also addresses common safety concerns, such as curb navigation and signaling, by incorporating large-diameter wheels, increased ground clearance, and electrically operated direction indicators. Future upgrades include the addition of a second rear wheel for enhanced stability, skateboard-like rear axle modifications for improved maneuverability, and hybrid supercapacitors to minimize fire risks and extend battery life. With its focus on safety, regulatory compliance, and rider-friendly innovations, this microvehicle represents a significant advancement in promoting safe and sustainable urban mobility. Full article

Objective: This study sought to examine the correlation between physical activity levels and various psychological and nutritional factors associated with the risk of developing eating disorders among female university students in the Health Sciences discipline. Method: The study assessed body image, self-esteem, nutritional status, adherence to the Mediterranean diet, and attitudes toward food in a sample of 96 women, categorized into two groups based on their level of physical activity. Results: Significant differences in skeletal muscle mass were identified between the groups, alongside associations between body dissatisfaction, low self-esteem, and elevated EAT-26 scores. Furthermore, students with higher levels of physical activity exhibited a significantly increased prevalence of eating disorder risk. Logistic regression analysis identified body dissatisfaction as a significant predictor of eating disorder risk, while membership in the group with the highest physical activity levels enhanced model fit and increased eating disorder risk. Conclusions: These findings indicate that, while physical activity is associated with certain benefits related to body composition and eating habits, it may also be linked to a heightened risk of disordered eating behaviors, contingent upon the underlying motivations and body perceptions involved. This study highlights the necessity for comprehensive preventive strategies that address both the physical and psychological dimensions of physical activity in female university students.

Background/Objectives: Personalized dietary recommendations are essential for managing chronic conditions such as diabetes and irritable bowel syndrome (IBS). However, traditional approaches often fall short in accounting for individual metabolic variability. This systematic review evaluates the effectiveness of artificial intelligence (AI)-generated dietary interventions in improving clinical outcomes among adults. Methods: Following PRISMA guidelines, we searched six electronic databases for peer-reviewed studies published between 19 November 2015 to 6 September 2024. Eligible studies included adults aged 18 to 91 who received AI-generated dietary recommendations based on biomarkers such as blood glucose, gut microbiome composition, and self-reported data. Study designs included randomized controlled trials (RCTs), pre-post studies, and cross-sectional analyses. The GRADE system was used to assess the quality of evidence. Results: Eleven studies met inclusion criteria (five RCTs, five pre-post designs, one cross-sectional). Most AI methods used in the included studies were based on machine learning (ML), including conventional ML algorithms, deep learning (DL), and hybrid approaches integrating ML with IoT-based systems. Interventions led to improved glycemic control, metabolic health, and psychological well-being. Notable outcomes included a 39% reduction in IBS symptom severity and a 72.7% diabetes remission rate. Among nine studies with comparison groups, six reported statistically significant improvements in AI groups, two found comparable or better outcomes, and one found no difference. Mild side effects such as fatigue and constipation were observed. Conclusions: AI-generated dietary interventions show promise in surpassing traditional approaches by providing personalized, data-driven recommendations. Further research is needed to validate long-term effects, refine intervention protocols, and enhance user adherence in both clinical and public health settings. Full article

To address the lack of theoretical understanding regarding crude oil wall adhesion in non-metallic pipelines and to compare it with the behavior in metallic pipelines, this study investigates the wall adhesion behavior of crude oil in non-metallic pipelines using a self-developed, simulated stirred tank setup. The main factors influencing crude oil adhesion in non-metallic pipelines were identified, and the differences in adhesion behaviors across different pipeline materials were clarified. Additionally, the reasons behind these behavioral differences were explored through contact angle measurements and the interfacial energy theory. The results indicate that the factors affecting the transportation temperature of crude oil in non-metallic pipelines include the overall water content, shear strength, and wax content of crude oil. On average, the amount of adhered crude oil in the three types of non-metallic pipeline was lower than that in the metallic pipelines. Among them, the flexible, composite non-metallic pipeline showed the greatest reduction in average adhered oil mass by 22.86%. This significant reduction is attributed to the reduced adhesion of crude oil on the non-metallic surfaces. Therefore, using non-metallic pipelines in crude oil transportation networks is advantageous for implementing low-temperature gathering and transportation processes. Full article

Significant body composition improvements were noted by 68.3% of the sample, and 87.6% reported changes in eating habits. Injury incidence was lower among women (30.2%) than men (45.3%) (p = 0.02). Regarding psychological outcomes, 95% of respondents indicated a reduction in stress levels, 73.3% reported better sleep quality, and over 90% perceived improvements in self-esteem and daily energy. Furthermore, 98.5% of participants formed new social connections through CrossFit^®, with 79.2% acknowledging a positive impact on social relationships. No significant gender differences were found across most psychological and social outcomes. Conclusions: CrossFit^® is perceived positively by participants, with similar views across genders, except for injury rates. It enhances physical fitness, mental health, and social well-being, with high training adherence and relatively low injury risk. Full article

(1) Background: Adolescence is a critical period in human life, particularly in relation to the development of a healthy lifestyle. Physical activity, body composition and adherence to healthy dietary patterns are key indicators for preventing adolescent overweight and obesity. The aim of this study is to explore the associations between systematic engagement in physical activity, dietary habits and body composition in a sample of Greek adolescents. (2) Methods: In this cross-sectional study, 292 adolescent volunteers, aged 12 to 18 years, from high schools in the Attica region (169 boys [57.9%] and 123 girls [42.1%]) participated. The participants’ socio-demographic characteristics and physical activity levels were assessed through self-reported questionnaires. Their dietary habits were evaluated using the KIDMED questionnaire, and their body composition was determined via bioelectrical impedance analysis. (3) Results: The majority of the students (80.8%) was involved in organized exercise, either as part of a team or in individual sports activities. Physically active participants had significantly improved body composition profiles compared to their non-active peers. No significant differences were observed in the KIDMED scores between boys and girls. However, significantly higher KIDMED scores were found in the group of physically active adolescents compared to the non-active group, with this difference being more pronounced among boys. (4) Conclusions: Engagement in organized physical activity is associated with healthier dietary choices, contributing to a more favorable overall lifestyle profile among adolescents. Full article

Background: Allergic asthma incidence is increasing, probably due to the influence of the Western diet. Adherence to the Mediterranean diet (MedDi) and omega-3 fatty acids composition (n-3 PUFAs) may be linked to a lower prevalence and lower severity of childhood asthma; however, the association is inconclusive. This study aims to examine the relationship between adherence to the MedDi, asthma severity, and erythrocyte fatty acid profile in Spanish children with atopic asthma. Methods: This study was based on an ongoing single-center, prospective, cross-sectional cohort study involving 95 consecutively enrolled children from an outpatient tertiary referral center. Of these, 55 had atopic asthma and 40 were age-matched healthy controls. Blood samples were collected to analyze the erythrocyte fatty acid content. Participants’ demographic and clinical characteristics were recorded using validated self-reported outcome measures. Asthma severity and pulmonary function were assessed. Results: Asthmatics presented poorer adherence to the MedDi (p = 0.034) and lower n-3 PUFA levels (p = 0.019). Asthmatics with poor adherence to the MedDi were more likely to be overweight (p = 0.001) and to have moderate-severe asthma (p = 0.049); and lower n-3 PUFAs levels (p = 0.033). Children with mild asthma had higher n-3 PUFAs levels than those with moderate or severe asthma (p = 0.036). Conclusions: These findings highlight that adherence to the MedDi and a high erythrocyte fatty acid profile seem to have a protective effect in childhood asthma. Future well-controlled interventions should focus on the effects of MedDi patterns and n-3 PUFA intake on the primary prevention of childhood asthma. Full article

Background: This study investigated the interdependent relationships among older adults’ daily engagement in physical activity (PA), sedentary time (ST), sleep, and their well-being, cognition, and body mass index (BMI). Method: Forty healthy older adults (31 females; Mean [age] = 70.8 ± 5.58) were included in the analysis. Participants wore a Fitbit tracker for an average of 23 h a day, five days a week, over six months. The Fitbit device tracked lightly active time, active time, ST, and sleep durations. Quality of life and cognitive flexibility were assessed using validated instruments. BMI was calculated using participants’ self-reported height and weight. A compositional analysis (CODA) investigated the codependent associations among these variables and model time reallocation between behaviors. Results: Regression models utilizing CODA indicated significant associations between the outcomes of BMI (p = 0.05; Adj. R² = 0.20), while cognitive flexibility and quality of life revealed no association (p > 0.05). Shifting 10 min from ST to active time is associated with a theoretical decrease of −0.76 (95% CI, −1.49 to −0.04) units in BMI. Similarly, reallocating 10 min from active time to ST is associated with a theoretical increase of 1.17 (95% CI, 0.03 to 2.3) units in BMI. Reallocating 10 min between other movement behaviors yielded no statistical significance. Conclusions: Our study highlights the importance of promoting active time to improve BMI in this population. Encouraging 10 min bouts of PA among older adults, in place of ST, is vital for improving national PA guideline adherence. Full article

Background: Dairy consumption has been associated with various health outcomes that may be mediated by changes in gut microbiota. Methods: This cross-sectional study investigated the association between the colonic mucosa-associated gut microbiota and the self-reported intake of total dairy, milk, cheese, and yogurt. A total of 97 colonic mucosal biopsies collected from 34 polyp-free individuals were analyzed. Dairy consumption in the past year was assessed using a food frequency questionnaire. The 16S rRNA gene V4 region was amplified and sequenced. Operational taxonomic unit (OTU) classification was performed using the UPARSE and SILVA databases. OTU diversity and relative abundance were compared between lower vs. higher dairy consumption groups. Multivariable negative binomial regression models for panel data were used to estimate the incidence rate ratio and 95% confidence interval for bacterial counts and dairy consumption. False discovery rate-adjusted p values (q value) < 0.05 indicated statistical significance. Results: Higher total dairy and milk consumption and lower cheese consumption were associated with higher alpha microbial diversity (adjusted p values < 0.05). Higher total dairy and milk consumption was also associated with higher relative abundance of Faecalibacterium. Higher milk consumption was associated with higher relative abundance of Akkermansia. Higher total dairy and cheese consumption was associated with lower relative abundance of Bacteroides. Conclusions: Dairy consumption may influence host health by modulating the structure and composition of the colonic adherent gut microbiota. Full article

Background: This study aimed to adapt and validate the Attitudes to Patient Safety Questionnaire (APSQ-III) for Brazilian Portuguese and to compare patient safety attitudes between medical and nursing students. Given the critical role of assessing safety attitudes in shaping future healthcare professionals, this research addresses a significant gap in the Brazilian educational context. Materials and Methods: The cross-cultural adaptation process adhered to the guidelines of for the Process of Cross-Cultural Adaptation of Self-Report Measures, encompassing translation, synthesis, back-translation, and expert committee evaluation. The adapted APSQ-III was administered to a sample of 423 undergraduate students from medicine and nursing courses. Confirmatory factor analysis (CFA) was conducted to verify the factor structure, while reliability was assessed using Cronbach’s alpha, McDonald’s omega, and composite reliability measures. Results: The CFA supported an acceptable fit for the nine-factor model with 26 items, following the exclusion of 4 items (χ²/df = 1.92; CFI = 0.90; TLI = 0.89; RMSEA = 0.05; SRMR = 0.07). Factor loadings ranged from 0.30 to 0.82, with satisfactory reliability indices, except for factors 4 (α = 0.47; ω = 0.48) and 9 (α = 0.54; ω = 0.54). Significant differences were discovered between medical and nursing students in four factors, and gender differences were noted in five items, highlighting the diverse perceptions of patient safety across these groups. Conclusions: The Brazilian version of the APSQ-III demonstrated adequate validity and reliability for seven out of the nine original factors. It is recommended to use the scale with modifications, such as developing a reduced version excluding factors with low reliability, to enhance its applicability. This study contributes to advancing patient safety research and education in Brazil, providing a robust tool for evaluating and improving safety attitudes among healthcare students. Future research should focus on refining the instrument and exploring its application in diverse healthcare educational settings across Brazil. Full article

Objectives: The aim of this study was to examine the adherence, changes in weight, and, waist circumference associated with the daily consumption of a culturally preferred food, namely an avocado, among Hispanic/Latina females in the Habitual Diet and Avocado Trial (HAT). Methods: HAT was a multisite, randomized controlled trial conducted between 2018 and 2020. Participants in the Avocado-Supplemented Diet Group were provided with and instructed to consume one avocado/day (~2.2 servings) for 6 months; participants in the Habitual Diet Group were instructed to follow their usual diet and limit intake to ≤2 avocados/month. Avocado consumption was assessed using three random 24 h dietary recalls administered by dietitians. This analysis focused on women who self-identified as Hispanic/Latina. Results: Within HAT, 158 females self-identified as Hispanic/Latina (median age: 42 years, IQR: 36–54). Across the dietary recalls, the Avocado-Supplemented Group (n = 80) consumed 1.9–2.1 avocado servings/day; the Habitual Diet Group (n = 78) consumed 0.04–0.09 servings/day (p < 0.001). The weight and waist circumference measurements were similar between groups. Hispanic/Latina females remained adherent to daily avocado consumption for the 6-month study period, without a significant change in their body weight or waist circumference measurements. Conclusions: Integrating a culturally preferred food into a dietary intervention enhanced adherence amongst Latina adults, with no impact significant impact on body composition. Full article

The appropriate use of food industry by-products such as watermelon seeds could reduce the problem of food waste, following the “zero waste” concept. Research in recent years suggests that these unused waste products could be a source of nutrients and bioactive compounds. Accordingly, the present study aimed to evaluate the nutritional potential and selected quality parameters of watermelon seed oils. Four commercial oils (three unrefined cold-pressed and one refined pressed) and one self-extracted oil were considered. The oils were analyzed over three months of storage after opening/extraction to determine their fatty acid (FA) composition and distribution, hydrolytic and oxidative stability, and selected health indices. Linoleic acid was the predominant FA, ranging from 52.9% (refined oil) to 62.2% (self-extracted oil). Refined oil demonstrated superior oxidative stability, with the lowest acid value (AV) and peroxide value (PV) throughout the storage period, adhering to the Codex Alimentarius standards. Unrefined oils, particularly WO₃, showed significantly higher AVs and PVs after storage, indicating greater susceptibility to hydrolytic and oxidative changes. Health indices were favorable for all oils, with self-extracted oil exhibiting the highest health-promoting index (7.07) and hypocholesterolemic/hypercholesterolemic ratio (7.18). Oxidative stability showed that self-extracted oil had significantly higher stability (76.6 min) than other tested oils, despite having the highest PUFA content. In turn, refinement has a significant effect on the AVs and PVs and the oxidative stability of oil, achieving the lowest PUFA level (53.61%). These results emphasize the potential of watermelon seed oil as a health-promoting product and emphasize the role of production and storage conditions in maintaining its quality. Full article
