Quantitative functional evaluation of a 3D-printed silicone-embedded prosthesis for partial hand amputation: A case report.

STUDY DESIGN: A male patient with partial hand amputation of his nondominant hand, with only stumps of the proximal phalanx of the first and fifth finger, was evaluated. The performance of using two alternative 3D printed silicone-embedded personalized prostheses was evaluated using the quantitative Jebsen Hand Function Test. INTRODUCTION: Custom design and fabrication of 3D printed prostheses appears to be a good technique for improving the clinical treatment of patients with partial hand amputations. Despite its importance the literature shows an absence of studies reporting on quantitative functional evaluations of 3D printed hand prostheses. PURPOSE OF THE STUDY: We aim at producing the first quantitative assessment of the impact of using 3D printed silicone-embedded prostheses that can be fabricated and customized within the clinical environment. METHODS: Alginate molds and computed tomographic scans were taken from the patient's hand. Each candidate prosthesis was modeled in Computer Aided Design software and then fabricated using a combination of 3D printed parts and silicone-embedded components. DISCUSSION: Incorporating the patient's feedback during the design loop was very important for obtaining a good aid on his work activities. Although the explored patient-centered design process still requires a multidisciplinary team, functional benefits are large. CONCLUSION(S): Quantitative data demonstrates better hand performance when using 3D printed silicone-embedded prosthesis vs not using any aid. The patient accomplished complex tasks such as driving a nail and opening plastic bags. This was impossible without the aid of produced prosthesis.

Estado nutricional y factores de riesgo cardiovascular en mujeres mapuche huilliche de la Provincia de Osorno / Nutricional state and cardiovascular risk factors in mapuche huilliche women in Osorno Province

Objetivos: Para disponer de información desagregada de la situación nutricional y presencia de factores de riesgo cardiovascular de la mujer mapuche huilliche y conformar una línea diagnóstica que sirva de base para estudios posteriores e iniciativas que la incluyan, se estudió una muestra estadísticamente representativa de mujeres de esa etnia, jefas de hogar, de zonas rurales y urbanas de la Provincia de Osorno. Material y método: Se utilizó un diseño no experimental, transeccional y descriptivo. Resultados: Se encontró que un 48,8 por ciento presenta un IMC>30, superando en 18,1 puntos porcentuales el promedio nacional equivalente. Un 42,1 por ciento presenta obesidad abdominal (circunferencia cintura >83cm) y el 73,5 por ciento tiene valores de alto riesgo en las razones de cintura-cadera y de cintura-estatura. Se presenta la relación de estos indicadores con variables como edad, ruralidad, presión arterial y reporte de enfermedades crónicas no transmisibles. Conclusiones: Se encontró alta prevalencia de factores de riesgo cardiovascular y baja concordancia entre IMC y percepción de estado nutricional.

Objective: In order to make available disaggregated information on nutritional state and cardiovascular risk factors among Mapuche Huilliche women, and establish a baseline for future studies and initiatives, a statistically representative sample of MapucheHuilliche women, heads of households, in rural and urban areas in Osorno Province. Materials and Methods: A non-experimental, cross-sectional, descriptive study design was used. Results: 48 percent had a BMI>30, 18.1 percent higher than the national average. 42.1 percent showed abdominal obesity (waist circumference >83cm) and 73.5 percent showed high risk values of waist-hip and waist-height ratios. The relationship of these indicators to other variables such as age, rural residence, blood pressure and chronic non transmissible diseases is discussed. Conclusions: A high prevalence of cardiovascular risk was found, as well as low perception of nutritional state as related to BMI.
