Mechanical properties of native and decellularized reproductive tissues: insights for tissue engineering strategies.

Understanding the mechanical properties and porosity of reproductive tissues is vital for regenerative medicine and tissue engineering. This study investigated the changes in Young's modulus (YM), storage modulus (E'), loss modulus (E"), and porosity of native and decellularized bovine reproductive tissues during the estrous cycle. Testis tunica albuginea had significantly higher YM, E', and E" than the inner testis, indicating greater stiffness and viscoelasticity. Endometrium showed no distinct differences in YM, E', or E" across the estrous cycle or between horns. Ovaries exhibited significant variations in YM, E', E", and porosity, with higher YM and E' in the ipsilateral cortex and medulla during the luteal phase. Decellularized ovarian tissues displayed increased porosity. The oviduct displayed no significant differences in YM or E' in the isthmus, but the contralateral ampulla had reduced YM and E' in the luteal phase. These findings offer valuable insights into the dynamic mechanical properties and porosity of reproductive tissues, facilitating the development of biomimetic scaffolds for tissue engineering applications.

[Minor surgery in primary care: consumer satisfaction]. / Cirugía menor en atención primaria: la satisfacción de los usuarios.

OBJECTIVE: To find the satisfaction of patients undergoing minor surgery at health centres and describe the processes. DESIGN: Retrospective study of population seeking the service. SETTING: Health district. PATIENTS: 160 people who had minor surgery during a year. MEASUREMENTS AND MAIN RESULTS: Descriptive variables of everyone who had minor surgery were analysed: age, sex, type of intervention, pre-surgical diagnosis, anatomical-pathological diagnosis and informed consent. Over three weeks the patients were interviewed by phone with use of a satisfaction questionnaire. 160 interventions took place, 80% of which were then studied histologically, with an 83.16% concordance index. 65% of patients were interviewed. 15% had no telephone, 20% were not found, 95.56% considered they were well attended and 3.17% badly attended. 92.06% would choose the health centre again for procedures of a similar nature. 89.9% thought that the explanations they had received were sufficient. 4.4% thought that the room's hygiene was poor. CONCLUSIONS: Minor surgery in primary care was favourably received by users. Activity at our centre had good anatomical-pathological concordance.

Objetivo. Conocer la satisfacción de los pacientes sometidos a técnicas de cirugía menor en un centro de salud y describir los procesos atendidos. Diseño. Estudio retrospectivo sobre población demandante del servicio. Emplazamiento. Zona básica de salud. Pacientes. Las 160 personas sometidas a cirugía menor en el período de un año. Mediciones y resultados principales. Se analizan variables descriptivas de todos los intervenidos (edad, sexo, tipo de intervención, diagnóstico prequirúrgico, diagnóstico anatomopatológico y consentimiento informado). Se entrevista telefónicamente a los pacientes en un período de 3 semanas, utilizando una encuesta de satisfacción. Se practicaron 160 intervenciones, remitiéndose el 80 por ciento a estudio histológico, con un índice de concordancia del 83,16 por ciento. Se entrevista al 65 por ciento de los pacientes. Un 15 por ciento no disponía de teléfono, no localizándose al 20 por ciento. Un 95,56 por ciento considera que fueron bien atendidos y el 3,17 por ciento mal atendidos. En un 92,06 por ciento elegiría de nuevo el centro de salud para procesos de características similares. El 89,9 por ciento opina que las explicaciones recibidas fueron bastantes. La higiene de la sala es calificada como mala por un 4,4 por ciento. Conclusiones. La realización de cirugía menor en atención primaria tiene una aceptación favorable entre los usuarios. La actividad realizada en nuestro centro tiene alta concordancia anatomopatológica (AU)
