Clinical and numerical precision of capillary glucose measurement devices available in the basic health plan for Colombia

Introducción: La glucometría tiene un rol crítico en el tratamiento del paciente tratado con insulina. Factores técnicos y medioambientales afectan significativamente la precisión de los glucómetros. El objetivo es establecer la precisión clínica y numérica de los glucómetros usados en Colombia, comparado con glucemia central. Métodos: Estudio de pruebas diagnósticas. Se evaluaron glucómetros del plan básico de salud (GluNeo, GlucoQuick, Optium Neo, Select Plus y Gluco Quick Diamond Voice). Se incluyeron adultos tratados con bomba de infusión de insulina integrada a sistema de monitoreo continuo. Se clasificaron las muestras en ≥100mg dL y 95 % según gradilla Parkes (Consensus) y Clarke, respectivamente. Se evidenció mayor variabilidad de los resultados en el rango ≤70 mg/dL. Conclusiones: La precisión numérica fue adecuada para los dispositivos evaluados para valores de glucosa capilar ≥100 mg/dL y disminuye con valores <100mg/dL. Gluco Quick Diamond Voice y Optium Neo tuvieron adecuada precisión clínica y numérica global.Pacientes con Diabetes mellitusIntroduction: Self-Monitoring blood glucose (SMBG) has a critical role in the management of patients treated with insulin. Technical and environmental factors significantly affect the accuracy of glucometers. The objective is to establish the clinical and numerical precision of the glucometers used in Colombia, compared to central blood glucose. Methods: Study of diagnostic tests, glucometers of the basic health plan (GluNeo, GlucoQuick, Optium Neo, Select Plus and Gluco Quick Diamond Voice) were evaluated. Adults treated with an insulin infusion pump integrated with a continuous monitoring system were included. The samples were classified as:>100mg dL,>70 and 100 mg/dL, ?70 mg/dL. For glucose ?100 mg/dL a bolus of insulin was delivered using the bolus wizard feature. The numerical precision was evaluated using the mean absolute relative difference (MARD) and the clinical precision according to the proportion measurements in the zones A + B of Clarke and Parkes (Consensus) error grids. Results: 830 measurements were analyzed. All devices met precision requirements for glucose >100mg / dL. Optium Neo and Gluco Quick Diamond Voice, achieved compliance standards by combining all measurement levels of 12.1% and 13.9%, respectively. The clinical precision for these two devices was 98% and >95% according to the Parkes (Consensus) and Clarke error grids, respectively. Greater variability of the results was evidenced in the range ?70mg/dL. Conclusions: The numerical precision was adequate for the devices evaluated for capillary glucose values >100mg/dL and decreases with values ??<100mg/dL. Gluco Quick Diamond Voice and Optium Neo had adequate global numerical and clinical precision.https://orcid.org/0000-0002-8907-3470https://orcid.org/0000-0002-6071-9178https://orcid.org/0000-0002-1353-148Xhttps://orcid.org/0000-0001-6838-3253https://orcid.org/0000-0001-5401-0018https://orcid.org/0000-0001-9572-2804https://orcid.org/0000-0002-0771-9857Revista Internacional - No indexadaN

Proximal Femur Endoprosthesis Augmentation with Polymethylmethacrylate and Condylar Plate : Surgical technique description

Q4Q4Introduction: Aseptic loosening by mechanical failure is one of the main causes of proximal femur endoprosthesis failure with different clinical consequences such as pain, inflammation, progressive loosening of muscular volume, and strength with functional limitation. Materials and Methods: We present the surgical description of the case of a patient with aseptic loosening of proximal femur endoprosthesis that was treated with a novel technique that combines different methods to achieve primary stability. Discussion: Different surgical techniques have been described to treat aseptic loosening of femoral endoprosthesis, including bone allografts, and total femur prosthesis which provides good functional results but high rates of complications such as infection (13%), dislocation (6%), and material failure (3%). Results: Proximal femur endoprosthesis augmentation with polymethylmethacrylate and condylar plate is a novel surgical technique that allows primary stabilization of the construct, early rehabilitation, improvement of functionality, and no signs of new loosening in a follow-up period of 6 months.https://orcid.org/0000-0003-0157-3639https://orcid.org/0000-0003-4913-7764https://orcid.org/0000-0002-0771-9857Revista Internacional - IndexadaCN
