Evaluating A Bilingual, Community-Based Skin Cancer Education Program In An Underserved Hispanic Population: An Item Response Theory Analysis, Smaran Marupudi, Natasha Quailes, Jared Hensley, Juan Lopez-Alvarenga, Maria Villegas

School of Medicine Publications

Background: Skin cancer prevention is often underemphasized in medically underserved regions such as the Rio Grande Valley (RGV), where residents, predominantly Hispanic and lower-income individuals, face limited access to dermatologic care and may be unaware of their risk for skin cancer.

Methods: The intervention included a bilingual educational session with a board-certified dermatologist and a seven-item knowledge survey administered before and immediately after the session, adapted from a previously validated instrument. A convenience sample of 73 participants completed both surveys. The instrument, adapted for this population, was evaluated using a two-parameter Item Response Theory (IRT) model to estimate participants’ underlying …

Introduction: We previously developed and tested a peer-led research best practices training for community health workers and promotoras (CHW/Ps) to enhance the capacity of a workforce that is increasingly important for community-engaged research. This paper explores results of training implementation at 4 additional sites – 3 academic institutions and 1 community-based organization.

Methods: Forty-two CHW/Ps were trained over 6 trainings and 10 site staff participated. We used a mixed methods design consisting of surveys and interviews to assess site staff’s perceptions of the training and its implementation. Survey data were examined using basic statistics and thematic content analysis. Two coders …

Una Nueva Herramienta Para Estimar El Volumen Muscular Independientemente De La Edad, El Sexo Y El Nivel De Actividad Física, José J. Rivera-Sánchez, Laura P. Burgos-Morelos, Daniel Castillo-Castillo, Gerardo Méndez-Suárez, Juan C. Lopez-Alvarenga, Damián Carrillo-Ruíz

Antecedentes: Actualmente, la evaluación del volumen muscular requiere técnicas invasivas o de imagen, lo que aumenta los costos y retrasa la evaluación, y las mediciones antropométricas con frecuencia son inexactas.

Objetivo: Desarrollar una fórmula matemática para estimar el volumen del cuádriceps.

Material y métodos: Se evaluaron 127 sujetos: 40 adultos sedentarios de 20 a 35 años, 47 atletas adultos de 20 a 45 años y 40 adultos sedentarios de 70 a 94 años. Se dividieron en grupos de desarrollo y de validación. Se realizaron mediciones de variables antropométricas y fuerza de agarre, y se desarrolló la fórmula de predicción del …

Relationship Between Cognitive Performance, Physical Activity, And Socio-Demographic/Individual Characteristics Among Aging Americans, Imtiaz Masfique Dowllah, Juan Carlos Lopez-Alvarenga, Gladys Maestre, Ulku S. Karabulut, Michael Lehker, Murat Karabulut

School of Medicine Publications

Background: Physical activity (PA) has emerged as a promising approach to delay Alzheimer’s disease and related dementias, but the optimal intensity of PA to improve cognitive health remains unknown.

Objective: To evaluate the association between duration and intensity of PA and cognitive domains (executive function, processing speed, and memory) in aging Americans.

Methods: Linear regressions in hierarchical blocks for variable adjustment and the size of effect (η2) were analyzed by using the data of 2,377 adults (age = 69.3±6.7 years) from the NHANES 2011–2014.

Results: Participants with 3–6 h/week of vigorous- and > 1 h/week of moderate-intensity PA scored significantly higher …
