“The objective of the present study is to make a comparison between various free and open-source software used for medical image processing, such as 3D Slicer (version 4.11), ITK-Snap (version 3.8), and Invesalius (version 3.1) in its application for the calculation of solitary fibrous tumor volumes. Knowing the size, shape, and volume of mesothelioma is decisive for clinical decisionmaking by health personnel when performing surgery; the currently used standard procedure is manual segmentation through magnetic resonance imaging (MRI). This process tends to take a long time to complete. On the other hand, automatic segmentation software is much faster and more user-friendly, so looking for software that gives us greater accuracy when doing this task is very important. This work obtained magnetic resonance imaging (MRI) of a mesothelioma patient, and the images were segmented in the 3 d...

En este artículo se presenta el desarrollo de una red inalámbrica de bajo costo, para el registro automático de los parámetros de temperatura y humedad ambiental en las instalaciones de los laboratorios de técnicas analíticas nucleares. El prototipo desarrollado cuenta con un sensor DHT22 que otorga ambos parámetros con alta precisión de manera automática, los mismos que son leídos y visualizados mediante un microcontrolador ATmega328P. Estos datos son luego transmitidos mediante transceivers Xbee Pro S2B formando una red mesh para su posterior almacenamiento en una memoria micro SD en tiempo real mediante un RTC (Real Time Clock). Se muestran los resultados experimentales obtenidos en la implementación del mismo.

Se presenta detalladamente el desarrollo, instalación y puesta en operación de sensores de nivel de agua y tasa de exposición gamma en el nivel 11 metros (boca de tanque) del reactor nuclear RP-10 utilizados para monitorear permanentemente estos valores y usarlos como vigilancia durante los períodos de no presencia de personal de operación (situación de desatención) con el reactor en estado apagado. Los niveles de estos parámetros son empaquetados y transmitidos a un controlador en la Sala de Control del reactor para su visualización y activación de niveles de alarma. Adicionalmente, se muestra el acondicionamiento de estas señales de alarma conjuntamente con la de detección de incendios en el edificio del rector y laboratorios auxiliares para ser transmitidas al edificio de seguridad física a una distancia de 500 metros.

“The correct distribution of loads on foot, known as plantar pressures, is a relevant parameter for evaluating the evolution of some diseases. Anomalies can lead to pain and discomfort in other body parts. Diabetes changes foot tissues and compromises biomechanics, resulting in ulcers and, eventually, amputation. Customized insoles allow the redistribution of plantar pressures and are a complementary strategy to diabetes management. Nowadays, scanning and 3D printing technology can generate faster and more accurate customized insoles opening new opportunities for local medical device development. This study reports the development of 3D-printed insoles using two polymers, thermoplastic polyether-polyurethane and thermoplastic polyurethane polyester-based polymer, and the evaluation of plantar pressure distribution in walk trials using a clinical protocol and low-cost electronic system....

“The birth of conjoined twins is one of the rarest neonatal conditions worldwide, with an incidence of 1 in 100,000 live births. Twins joined by the pelvis, known as ischiopagus, represent 6–11% of all conjoined twins. This clinical condition increases the degree of complexity in separation surgeries. Each case poses unique anatomical challenges, and clinical outcomes may vary according to the health facility where the infants are born or can access. This case report describes a successful separation surgery of ischiopagus conjoined twins in Peru. 3D printing and neurophysiological monitoring were used for surgical planning and intervention, allowing a fullscale anatomical model and preserving the mobility of the lower limbs of conjoined twins after surgery. This article demonstrates that established procedures and novel technologies can be valuable platforms for preoperative plannin...
