RESUMO
BACKGROUND: Around 15 million premature babies are born annually, requiring specialized care. Incubators are vital for maintaining their body temperature, which is crucial for their well-being. Ensuring optimal conditions in incubators, including constant temperature, oxygen control, and comfort, is essential for improving the care and survival rates of these infants. METHODS: To address this, an IoT-based monitoring system was developed in a hospital setting. The system comprised hardware components such as sensors and a microcontroller, along with software components including a database and a web application. The microcontroller collected data from the sensors, which was then transmitted to a broker via WiFi using the MQTT protocol. The broker validated and stored the data in the database, while the web application provided real-time access, alerts, and event recording. RESULTS: Two certified devices were created, employing high quality components. The system was successfully implemented and tested in both the biomedical engineering laboratory and the neonatology service of the hospital. The results of the pilot test supported the concept of IoT-based technology, demonstrating satisfactory responses in temperature, humidity, and sound variables within the incubators. CONCLUSIONS: The monitoring system facilitated efficient record traceability, allowing access to data over various timeframes. It also captured event records (alerts) related to variable problems, providing information on duration, date, hour, and minutes. Overall, the system offered valuable insights and enhanced monitoring capabilities for neonatal care.

Background: Conventional periodontal therapy relies on bone regeneration strategies utilizing scaffolds made of diverse materials, among which collagen, to promote cell adhesion and growth. Objective: To evaluate periodontal ligament fibroblast (HPdLF) cell adhesion and viability for periodontal regeneration purposes on hydroxyapatite scaffolds containing collagen (HAp-egg shell) combined with polylactic acid−polyglycolic acid copolymer (PLGA) and Platelet-Rich Fibrin (PRF). Methods: Four variations of the HAp-egg shell were used to seed HPdLF for 24 h and evaluate cell viability through a live/dead assay: (1) (HAp-egg shell/PLGA), (2) (HAp-egg shell/PLGA + collagen), (3) (HAp-egg shell/PLGA + PRF) and (4) (HAp-egg shell/PLGA + PRF + collagen). Cell adhesion and viability were determined using confocal microscopy and quantified using central tendency and dispersion measurements; significant differences were determined using ANOVA (p < 0.05). Results: Group 1 presented low cell viability and adhesion (3.70−10.17%); groups 2 and 3 presented high cell viability and low cell adhesion (group 2, 59.2−11.1%, group 3, 58−4.6%); group 4 presented the highest cell viability (82.8%) and moderate cell adhesion (45%) (p = 0.474). Conclusions: The effect of collagen on the HAp-egg shell/PLGA scaffold combined with PRF favored HPdLF cell adhesion and viability and could clinically have a positive effect on bone defect resolution and the regeneration of periodontal ligament tissue.
RESUMO
Objetivo: Evaluar los factores relacionados con la maternidad adolescente, con relación a un grupo de gestantes adultas y las particularidades potenciales que pueden repercutir en la salud de la madre y el neonato. Materiales y métodos: Estudio de corte transversal. Se incluyeron todas aquellas gestantes cuyos partos fueron atendidos en el centro de salud San Cayetano de ASSBASALUD E.S.E (Manizales, Colombia) entre los años 2009 y 2010. Resultados: Se analizaron 900 historias, el 99% de los partos fue vaginal, 64,2% de las gestantes <19 años presentó complicaciones en el parto, siendo la necesidad de episiotomía la más frecuente, 33,3%. El promedio de peso neonatal fue 3063 gr con 4,3% de bajo peso, el 49,6% de las gestantes >19 años tuvieron complicaciones en el parto siendo el desgarro grado II la más frecuente, promedio de peso neonatal 3163 con 3,1% de bajo peso. No hubo diferencias significativas entre ambos grupos en mortalidad materna, neonatal, malformación fetal, índice apgar al minuto, a los 5 minutos, talla neonatal, número de controles prenatales, etc. Además entre ambos grupos hubo diferencias significativas en consumo de sustancias, planeación del embarazo, escolaridad, empleo de anticonceptivos, peso materno, edad de inicio de relaciones sexuales, número de gravideces, y de partos, entre otras. Conclusiones: Si bien en esta población hay diferencias significativas entre adolescentes y adultas en peso del recién nacido, y complicaciones en el parto, estas asimetrías no son suficientes para producir diferencias de morbimortalidad entre los neonatos de gestantes adolescentes y adultas...
