RESUMO

OBJECTIVE: To determine the level of agreement within and between observers in the categorization of breast density on mammograms in a group of professionals using the fifth edition of the American College of Radiology's BI-RADS® Atlas and to analyze the concordance between experts' categorization and automatic categorization by commercial software on digital mammograms. METHODS: Six radiologists categorized breast density on 451 mammograms on two occasions one month apart. We calculated the linear weighted kappa coefficients for inter- and intra-observer agreement for the group of radiologists and between the commercial software and the majority report. We analyzed the results for the four categories of breast density and for dichotomous classification as dense versus not dense. RESULTS: The interobserver agreement among radiologists and the majority report was between moderate and nearly perfect for the analysis by category (κ=0.64 to 0.84) and for the dichotomous classification (κ=0.63 to 0.84). The intraobserver agreement was between substantial and nearly perfect (κ=0.68 to 0.85 for 4 categories and k=0.70 to 0.87 for the dichotomous classification). The agreement between the majority report and the commercial software was moderate both for the four categories (κ=0.43) and for the dichotomous classification (κ=0.51). CONCLUSION: Agreement on breast density within and between radiologists using the criteria established in the fifth edition of the BI-RADS® Atlas was between moderate and nearly perfect. The level of agreement between the specialists and the commercial software was moderate.

RESUMO

BACKGROUND: There is a tendency for the aging population to fracture their hips. Our aim was to compare survival and functionality at one year, among elderly and very elderly patients with hip fracture. MATERIAL AND METHODS: A prospective cohort of patients included in the Institutional Registry of Elderly Patients with Hip Fracture between 2014 and 2017. We classified patients as elderly patients (EP) <65 and <85 years and very elderly patients (VEP) ≥85 years. RESULTS: We included 952 patients, 43% were EP and 57% were VEP. The proportion of women was 84% and 86% (P=.33) and with 2 or more points in the Charlson comorbidities index (28 and 31%, P= .36), respectively. The VEP were more dependent according to the Barthel score (34% and 62%, P<.01) and frailer according to the Edmonton score (30% and 61%, P<.01). One-year survival was 91% (95% CI 86-93) in the EP and 76% (95% CI 70-89) in the VEP. In-hospital complications were more frequent in the VEP 12% (7% in the EP, P<.01). Age is an independent risk factor for one-year survival (HR 2.11; 95% CI 1.36-3.29, P<.001). CONCLUSIONS: Age is a risk factor for the VEP group survival despite fragility and comorbidities. Because of their vulnerability, an appropriate care plan should be considered for VEP.

RESUMO

OBJETIVOS: Evaluar la posible asociación entre el uso de análogos de prostaglandinas (AP) y el desarrollo de membrana epirretinal (MER) en pacientes con glaucoma. MÉTODO: Mediante el método comparativo se realizó un diseño retrospectivo de casos y controles. Se compararon pacientes que presentaban glaucoma y, a su vez, MER y que utilizaban una mayor proporción de AP con un grupo control de pacientes que presentaban glaucoma pero sin MER. El diagnóstico de MER ha sido realizado mediante un examen clínico y un estudio de tomografía de coherencia óptica. RESULTADOS: La edad media de los casos ha sido de 77 años, con DE de 8,68 (IC 95%: 74,3-79,4) y la de los controles de 63 años, con DE de 16,6 (IC 95%: 70,1-78,5). El 50% de los casos (n = 26) estaba compuesto por hombres y el otro 50% eran mujeres (n = 26), mientras que para los controles el 25,4% eran hombres (n = 16) y el 74,6% eran mujeres (n = 47). El 59,6% de los casos (n = 31) y el 60,3% de los controles (n = 38) fueron tratados con AP. No se ha observado ninguna diferencia de colocación de AP entre ambos grupos (p = 0,939). CONCLUSIONES: En este trabajo no hemos podido demostrar si existe asociación entre el uso de AP y el desarrollo de MER


OBJECTIVES: To determine whether patients with glaucoma and epiretinal membrane (ERM) use a greater proportion of prostaglandin analogues (PA) than a control group of patients with glaucoma without ERM. METHOD: A retrospective study of cases and controls was conducted in order to determine whether patients with glaucoma and ERM used a greater proportion of PA than a control group of patients with glaucoma without ERM. The diagnosis of de ERM was made by clinical examination and optical coherence tomography. RESULTS: The mean age of the cases was 77 years (SD: 8.68; 95% CI: 74.3-79.4), compared to the controls with 63 years (SD: 16.6; 95% CI: 70.1-78.5). The cases included 50% (n = 26) men and 50% women (n=26), whereas in the controls 25.4% (n = 16) of the cases were men and 74.6% (n = 47) women. PA treatment was used in 59.6% (n = 31) and 60.3% (n = 38) of the cases and controls, respectively. There was no statistically significant difference in PA use between the 2 groups (P = .939). CONCLUSIONS: In this study, an association between the use of AP and the development of ERM could not be demonstrated
