ArticleA Sustainable mHealth Intervention to Promote Physical Activity for Healthy Aging: A Pilot Study of the “Every Walk You Take” Citizen Science Initiative(MDPI, 2024-06-23) Naik, Preet; Álamo Junquera, María Dolores; Igual Muñoz, Laura; Serrajordi Domènech, Marc; Pérez González, Alba; Pericas Escale, Carles; Pagès Fernández, Constança; Katapally, Tarun Reddy; Grau, MariaThe objective of the Every Walk You Take initiative was to co-design and test, in a pilot study, a sustainable mHealth intervention prototype (mobile app) to promote physical activity. This prototype would help to identify the barriers to and facilitators of active living in individuals older than 55 years. A prototype of the intervention was co-designed by a community of stakeholders in Barcelona who were familiar with the social and economic burden of aging in high-income societies. The app’s functionalities included recommendations for healthy routes in the city (parks, pedestrian lanes, and streets) according to environmental variables (air quality and climate) and personal preferences (route difficulty, distance, and geolocation), and ecological momentary assessments (pictures and voice notes) were collected to identify the barriers to and facilitators of performing these routes. To test the app, a pilot study was conducted over two 7-day cycles with citizen scientists recruited at the life-long learning centers of two deprived neighborhoods in Barcelona. A total of 21 citizen scientists (mean age = 67 (standard deviation = 7)), 86% of them female, collected 112 comments and 48 pictures describing their perceived barriers to and facilitators of active living. Every Walk You Take is a new, validated, and sustainable mHealth intervention that is directly involved in health promotion, as it empowers the citizens of Barcelona to play an active role in their own healthcare. This intervention has the potential to be implemented in different cities around the world to collect information on the community determinants of health and health assets.- ArticleLifestyle and Cardiovascular Risk Factors by Educational Attainment in a Mediterranean Setting: A Cross-Sectional Analysis of a Population-Based Sample(Ubiquity Press, 2026-07-14) Álamo Junquera, María Dolores; Vilaplana Carnerero, Carles; Pagès Fernández, Constança; Toledo Zavaleta, Diana Isabel; Soldevila, Núria; Tor Roca, Alba; Domínguez García, Àngela; Grau, MariaBackground: Socioeconomic inequalities in cardiovascular risk persist despite declining mortality. We examined the prevalence of cardiovascular risk factors and lifestyle behaviors across educational levels in men and women from a Mediterranean population. Methods: Cross-sectional analysis of adults aged 35–74 years from a population-based sample in north-eastern Spain. Risk factors and lifestyle were assessed with standardized measurements and validated questionnaires. Educational attainment was categorized as primary, secondary, or university. Analyses were sex-stratified; age-adjusted linear and logistic regression models were applied. Results: We included 943 adults (52.3% women). Among men, secondary and university education (vs. primary) were associated with lower LDL-cholesterol [β –11.76 (95% CI –21.68 to –1.83) and –17.83 (–28.03 to –7.63) mg/dL], lower odds of hypercholesterolemia [OR = 0.43 (0.20–0.90) for both], smoking [OR = 0.57 (0.33–0.97) and 0.53 (0.30–0.95)], and higher odds of high Mediterranean diet adherence [OR = 2.08 (1.04–4.16) and 3.05 (1.51–6.14)]. Among women, secondary and university education (vs. primary) were associated with lower body mass index [β –1.81 (–2.85 to –0.77) and –2.52 (–3.63 to –1.40) kg/m2] and lower odds of overweight/obesity [OR = 0.47 (0.29–0.76) and 0.34 (0.20–0.56)]. Lower odds of hypertension [OR = 0.44 (0.22–0.87)] and high Mediterranean diet adherence [OR = 2.14 (1.12–4.09)] were also more likely in university-educated women. Conclusions: Higher educational attainment was associated with healthier lifestyles and more favorable cardiometabolic profiles. Educational gradients were broader in women—spanning adiposity, blood pressure, glycemia, and lipidemia—whereas, in men, they mainly affected lipidemia and diet.
- ArticleTopographic Organization of Median Nerve Muscular Branches Reveals Frequent Shared Motor Pathways in the Human Forearm(MDPI, 2026-10-05) Merí Vived, Àlex; López Plaza, Pedro Victor; Morral Fernández, Antoni; Llusá Pérez, Manuel; García-Cuesta, Marcel; Casado, AroaLes descripcions anatòmiques clàssiques de la innervació motora del nervi medià acostumen a relacionar cada branca muscular amb un múscul específic. Tanmateix, una mateixa branca pot dividir-se i proporcionar innervació a diversos músculs, fet que dificulta la interpretació de l'organització jeràrquica de les branques motores. L'objectiu de l'estudi va ser caracteritzar l'organització topogràfica de les branques musculars del nervi medià a l'avantbraç humà i analitzar la freqüència de les vies motores compartides. Material i mètodes: Es va realitzar un estudi anatòmic sobre 16 avantbraços drets humans. Es van identificar i descriure 70 branques musculars del nervi medià mitjançant un sistema de referència basat en coordenades anatòmiques i l'ordenació proximodistal dels seus orígens. Resultats: L'anàlisi va posar de manifest que el 45,7% de les branques musculars proporcionaven innervació a més d'un múscul, fet que indica que les vies motores compartides constitueixen una característica freqüent de la ramificació del nervi medià. Es va descriure l'organització de les branques segons el seu ordre d'origen, però la distribució observada és descriptiva i no demostra per si mateixa una localització reproduïble i independent de les branques nervioses. Conclusions: L'organització de les branques musculars del nervi medià presenta una complexitat superior a la representada pels models anatòmics convencionals basats en una correspondència directa entre branca i múscul. Els mapes d'origen de les branques permeten descriure la seva organització topogràfica, però no s'han d'interpretar com a mapes de bifurcacions distals, punts d'entrada motora o arborització intramuscular. La identificació específica de les branques i de les seves destinacions musculars continua sent necessària. L'estudi contribueix al coneixement anatòmic del nervi medià i proporciona una base per a futures investigacions.

- ArticlePopulation-Based Quantitative Spatial Mapping of Ulnar Motor Branch Origins in the Forearm: An Integrated Anatomical Reference Framework(MDPI, 2026-09-02) Merí Vived, Àlex; López Plaza, Pedro Victor; Morral Fernández, Antoni; Llusá Pérez, Manuel; García-Cuesta, Marcel; Casado, AroaBackground/Objectives: The extramuscular branching pattern of the ulnar nerve shows substantial interindividual variability, limiting the value of single-pattern anatomical descriptions. It remains unclear whether the origins of its motor branches are spatially random or retain reproducible relationships with the neural, anthropometric, and musculotendinous organization of the forearm. This study characterized the normalized spatial distribution of the origins of the main ulnar motor branches supplying the flexor carpi ulnaris (FCU) and the ulnar portion of the flexor digitorum profundus (FDP), and examined their relationships with anatomical reference variables measured during dissection. Methods: A cross-sectional cadaveric study was conducted on 16 adult right upper limbs. Fifteen specimens were dissected fresh on the day they were received by the Body Donation Programme; one specimen was frozen at -80 °C, thawed overnight, and dissected the following morning. Standardized anatomical dissection identified 54 main motor branches arising from the ulnar nerve and confirmed their target muscles by direct anatomical continuity (36 FCU and 18 FDP branches). For quantitative mapping, only the origin of each branch on the parent ulnar nerve was recorded using a laser-guided Cartesian coordinate system. Anthropometric dimensions and topographical landmarks were normalized to the corresponding forearm dimensions. Spatial organization was characterized using centroids, 95% data ellipses, Euclidean centroid distances, and a specimen-level cluster bootstrap. Generalized estimating equations (GEE) were used for cluster-aware group comparisons and exploratory multivariable association analysis, while ROC analysis and leave-one-cadaver-out cross-validation quantified internal separation and stability within the cadaveric dataset. Results: FCU and FDP branch origins occupied reproducible but partially overlapping normalized spatial territories. Their centroids differed in location, and specimen-level bootstrap resampling supported the stability of the observed separation. Cluster-aware analyses confirmed differences in the proximodistal branch-origin coordinate and in the tendon-crossing landmark. In the multivariable GEE model, the normalized tendon-crossing landmark showed the strongest adjusted association with group membership, while the proximodistal coordinate also remained associated. Conclusions: Despite marked interindividual variation in ulnar nerve branching, the origins of its main motor branches exhibit reproducible population-level spatial organization. Their distributions are related to the anatomically confirmed target muscle and to normalized neural, anthropometric, and musculotendinous landmarks measured during dissection. This integrated reference framework supports interpretation of peripheral motor innervation as an organized spatial system rather than a collection of isolated variants. The findings provide an anatomical basis for future imaging and image-guided research; however, the exploratory regression and ROC analyses do not constitute a clinically validated diagnostic model.
