    Polygastric flexor muscle of the index finger and its clinical implications
    (2023) Riveros, Andrés; Inzunza, Óscar; Burdiles, Álvaro; Farfán, Emilio
    Although muscle variations in the forearm have been widely reported, the presence of supernumerary muscles in this compartment may be associated with compressive disorders of the nerves of the upper limb. The purpose of this study was to report the finding of a polygastric flexor muscle of the index finger (PFID), a supernumerary muscle associated with the anterior compartment of the forearm, the morphology and pathway of which are closely related to the median nerve. The PFID was found in a routine dissection of an upper right limb. Following a dissection methodology by planes, a narrow, polygastric muscle was identified, formed sequentially and interspersed by four tendons and three muscle bellies, that extended between the common flexor muscle mass of the anterior compartment of the forearm and the index finger. The sixth part of the PFID was partially in the carpal tunnel and established close relation with the median nerve, which was displaced superficially. Knowledge of this and other muscle variations that appear in the forearm and carpal tunnel are relevant when performing a differential diagnosis of carpal tunnel syndrome or in planning surgery on this canal.

    Profile of morphology teachers in chilean universities
    (2021) Farfán C., Emilio; Cárdenas, Julio; Espinoza Navarro, Omar; Lizana, Pablo A.; Pacheco, Juan; Salinas, Paulo; Riveros, Andrés; Villarroel, Mauricio
    University teaching in Chile has been influenced in recent decades by changes to the education system, which has increased universities and academic offerings and, therefore, the demand for new instructors. Teaching morphological sciences has not been exempt from these changes, with new instructors needed to fill the growing offerings of programs that include anatomy, embryology and histology. The aim was to understand the profile of the academics teaching morphology in Chile in 2020. A voluntary online survey was applied to 213 university morphology teachers, in which information was collected on professional and academic training, geographical distribution, gender, continuing academic education and employment situation. Overall, the results show that 65.9 % of instructors were men and 35.1 % women, and most (34.6 %) had between 5 and 10 years in morphology, and a master's degree was predominant (53.27 %). In the area of anatomy, 46 % of instructors were physiotherapists and 24.6 % dentists, whereas in the areas of histology and embryology, the group was diverse. In terms of employment, 49.06 % stated they worked full time, mainly in teaching .41.31 % of the instructors were concentrated in the Metropolitan Region. There was no association between gender and graduate training, maximum academic degree attained, type of workday or academic profile, but there was one by disciplinary area. The conclusion drawn is that morphology teachers in Chilean universities are part of a wide range of professionals dedicated to different disciplinary areas, with master's degree and/or specialization, located mainly in the Metropolitan Region. This multidisciplinary profile demonstrates the mainstreaming of morphology teaching in Chile.

    Urban Wetlands in Latin America: Protection, Conservation, Innovation, Restoration, and Community for Sustainable and Water Sensitive Cities
    (Springer Cham, 2024) Aldana-Domínguez, Juanita; Rojas Quezada, Carolina Alejandra; Munizaga, Juan; Moschella, Paola; Stamm, Caroline Andre; Martínez, Carolina; Velásquez, Carlos Javier; Capera, Ingrid; Falfán, Ina; Zambrano, Luis; Soto, Evelyn; Teutsch, Camila; Scheuch, Teresita; Fernández, Antonio; Briceño, Felipe; Vattuone Troncoso, Catalina de los Angeles; Domínguez, Juan Carlos; Riveros, Andrés; Pichunleo, Enzo; Rojas Quezada, Carolina Alejandra
    This book is about the contribution of urban wetlands in livable cities. Urban wetlands are very valuable blue-green infrastructure spaces for human settlements, yet they are disappearing as a result of urbanization. This phenomenon is worldwide, but is particularly intense in Latin America. Although international literature has made an effort to document the multiple ecosystem services provided by these ecosystems, such as water and air cleansing, flood mitigation and recreation, among others, we want to draw attention to the fact that the loss of urban wetlands affects the sustainability of cities and future generations. Therefore, and given the weakness of public policies implemented in the region for their protection, it is essential to highlight good practices, mechanisms and strategies aimed at Protection, Conservation, Innovation, Restoration, and work with the Community, all of this hand in hand with the 17 Sustainable Development Goals.The book offers a comprehensive coverage combining the need to protect and conserve urban wetlands from the pressures of urban growth, as well as highlighting successful experiences of regulation and of course applied research aimed at nature-based solution design for flood management and wastewater treatment, restoration areas, green infrastructure plans, as well as experiences of collective work with communities in contexts of political tensions for the defense of wetlands.
