Publication Delivery of Health Care by Spanish Dental Hygienists in Private and Public Dental Services during the COVID-19 De-Escalation Phase (June 2020): A Cross-Sectional Study(MDPI, 2021-08-05) Expósito Delgado, Antonio Javier; Ausina Márquez, Verónica; Mateos Moreno, María Victoria; Martínez Sanz, Elena; del Carmen Trullols Casas, María; Llamas Ortuño, María Eulalia; Blanco González, José María; Almerich Torres, Teresa; Bravo, Manuel; Martínez Beneyto, YolandaBackground: The first wave of the COVID-19 pandemic in Spain posed a major challenge for Spanish dental professionals. The objective of this work is to describe the dental hygienists’ work status and employment patterns during the de-escalation phase in order to analyse the standards of knowledge, compliance with official recommendations, and dental activities both in the public health service and in the private sector. Material and Methods: A cross-sectional questionnaire was answered by Spanish dental hygienists via WhatsApp, Facebook, and Instagram. The questionnaire was piloted before it was distributed and carried out during June 2020. Results: Here, 517 dental hygienists were surveyed, of which 86.2% followed the official recommendations to avoid contagion and 63.8% agreed with the gradual return to work by limiting the use of aerosols. Private dental hygienists identified more with returning to work without restrictions (14.5%) versus those working for the public service (1.2%) (p < 0.005). Conclusions: Dental hygienists’ return to work has involved different strategies, aimed at controlling infection and guaranteeing the safety of patients and the rest of the dental team. The availability of personal protective equipment, the adaptation of clinical infrastructure, and patient care management have differed between professionals working in the private and public sectors.Publication Tomando medidas ante la COVID-19: Virtualización de las prácticas de Aparato Locomotor en las asignaturas que imparte el Departamento de Anatomía y Embriología en las titulaciones de Medicina, Fisioterapia, Podología y Terapia Ocupacional(2022-01-28) Arraez Aybar, Luis Alfonso; Barrio Asensio, María del Carmen; Catón Vázquez, Francisco Javier; Cuadra Blanco, Crótida de la; Garcia Gómez, Susana; Maldonado Bautista, Estela; Martínez Sanz, Elena; Mérida Velasco, José Ramón; Murillo González, Jorge Alfonso; Quirós Terrón, Luis; Sanz Casado, José Vicentedesarrollo de un sistema interactivo para mejorar el proceso de enseñanza-aprendizaje en la docencia de las prácticas del Aparato Locomotor, que pudiera ser utilizado por los alumnos de Grado de Fisioterapia, Medicina, Podología y Terapia Ocupacional, titulaciones en las que el Aparato Locomotor tiene una importante presencia en sus temarios de prácticas.Publication Maternal Folic Acid Deficiency Is Associated to Developing Nasal and Palate Malformations in Mice(MPDI, 2021-01-16) Maldonado Bautista, Estela; Martínez Sanz, Elena; Partearroyo, Teresa; Varela Moreiras, Gregorio; Pérez Miguelsanz, JulianaCraniofacial development requires extremely fine-tuned developmental coordination of multiple specialized tissues. It has been evidenced that a folate deficiency (vitamin B9), or its synthetic form, folic acid (FA), in maternal diet could trigger multiple craniofacial malformations as oral clefts, tongue, or mandible abnormalities. In this study, a folic acid-deficient (FAD) diet was administered to eight-week-old C57/BL/6J female mouse for 2–16 weeks. The head symmetry, palate and nasal region were studied in 24 control and 260 experimental fetuses. Our results showed a significant reduction in the mean number of fetuses per litter according to maternal weeks on FAD diet (p < 0.01). Fetuses were affected by cleft palate (3.8%) as well as other severe congenital abnormalities, for the first time related to maternal FAD diet, as head asymmetries (4.6%), high arched palate (3.5%), nasal septum malformed (7.3%), nasopharynx duct shape (15%), and cilia and epithelium abnormalities (11.2% and 5.8%). Dysmorphologies of the nasal region were the most frequent, appearing at just four weeks following a maternal FAD diet. This is the first time that nasal region development is experimentally related to this vitamin deficiency. In conclusion, our report offers novel discoveries about the importance of maternal folate intake on midface craniofacial development of the embryos. Moreover, the longer the deficit lasts, the more serious the consequent effects appear to be.Publication Functional hypothesis of the juxtaoral organ: Role of collagen types I and III(Wiley, 2021-07-12) Mérida‐García, Antonio José; Murillo González, Jorge Alfonso; Martínez Sanz, Elena; Catón Vázquez, Javier; Arráez‐Aybar, Luis A.; Martín‐Cruces, José; Cobo, Teresa; Vega, José Antonio; Mérida Velasco, José RamónPublication Desarrollo de un sistema interactivo para el estudio de la órbita y su contenido: anatomía macroscópica(2023-06) Asensio, Carmen; Arráez Aybar, Luis Alfonso; Catón Vázquez, Francisco Javier; García Serradilla, Moisés; Garcia Gómez, Susana; García de Pereda Notario, Carlos Miguel; Maldonado Bautista, Estela; Martínez Sanz, Elena; Mérida Velasco, José Ramón; Murillo Barrio, Jaime; Murillo González, Jorge Alfonso; Naredo Sánchez, Esperanza; Paradas Lara, Irene; Virto Ruiz, LeireEn este proyecto se ha desarrollado un sistema interactivo para mejorar el proceso de enseñanza-aprendizaje en la docencia de la anatomía macroscópica de la órbita y su contenido por medio de preparaciones anatómicas.

To date, this type of preparation for coping with cadaver dissection has not been studied in Spanish universities. The aim of this study is to evaluate how first-year Spanish medical students face the dissecting room and whether previous preparation about death and dying reduces the stress generated. We performed an interventional study with students who received preparatory classes before the dissection practices (Experimental Group, EG) and with students who did not (Control Group, CG). Sociodemographic data and a self-assessment on stress symptoms were collected through a questionnaire completed before and after the dissection practices. No differences were found in the self-report of symptoms of stress among students who consider themselves religious or not, or between students who had a family member in the healthcare environment or not. However, in the EG, the students who had ample experience with terminally ill patients or death reported fewer stress symptoms. Unexpectedly, the number of self- reported stress symptoms after the dissection practice was higher in EG students. In conclusion the stress levels of first-year Spanish medical students not only did not improve after receiving preparatory classes about death and dying and discussion groups, but it gets worse. We found a relationship between student stress measured and experience with terminally ill patients or death. Additional studies are needed to identify the most suitable preparation for Spanish medical students.Publication Programación infográfica para la representación de los huesos y articulaciones del miembro inferior(2021-01-15) Martínez Sanz, Elena; Murillo González, Jorge Alfonso; Arráez Aybar, Luis Alfonso; Barrio Asensio, María del Carmen; Herrera Lara, Manuel Eugenio; Cabrera Parra, Walter; Dorado Fernández, Enrique; Maldonado Bautista, Estela; Mérida Velasco, José Ramón; Catón Vázquez, Francisco Javier; Cuadra Blanco, Crótida de la; Garcia Gómez, Susana; Becerro de Bengoa Vallejo, RicardoDesarrollo de una infografía con los huesos y articulaciones del miembro inferior para mejorar el proceso de enseñanza-aprendizaje en la docencia de la anatomía topográfica de estas estructuras a través del campus virtual (Grados de CC. de la Salud).Publication Study of the functional relationships between the buccinator muscle and the connective tissue of the cheek in humans(Elsevier, 2022-11-12) Martínez Sanz, Elena; Catón Vázquez, Javier; Maldonado Bautista, Estela; Murillo González, Jorge Alfonso; Barrio Asensio, María Carmen; Paradas Lara, Irene; García Serradilla, Moisés; Arráez Aybar, Luis; Mérida Velasco, José RamónBackground: The buccinator muscle derives from the mesenchyme of the second pharyngeal arch. In adults, it has a quadrilateral shape, occupying the deepest part of the cheek region. Its function is complex, being active during swallowing, chewing, and sucking. To our knowledge, there are no studies that have specifically analyzed the relationship of the buccinator muscle fibers and neighboring connective tissue of the cheek in humans, neither during development nor in adults. Such relationships are fundamental to understand its function. Thus, in this study the relations of the buccinator muscle with associated connective tissue were investigated. Methods: The buccinator muscle region was investigated bilaterally in 41 human specimens of 8–17 weeks of development. Moreover, four complete adult tissue blocks from human cadavers (including mucosa and skin) were obtained from the cheek region (between the anterior border of the masseter muscle and the nasolabial fold). All samples were processed with standard histological techniques. In addition, subsets of sections were stained with picrosirius red (PSR). Furthermore, immunoreactivity against type I and III collagen was also studied in adult tissues. Results: The buccinator muscle showed direct relationships with its connective tissue from 8 to 17 weeks of development. Collagen fibers were arranged in septa from the submucosa to the skin through the muscle. These septa were positive for type I collagen and presented elastic fibers. Fibrous septa that were positive for type III collagen were arranged from the lateral side of the muscle to the skin. Conclusions: The intimate relationship between buccinator muscle fibers and cheek connective tissue may explain the complex functions of this muscle.
