[Translated article] Diagnostic imaging in patients with vertebral compression fractures.

Vertebral compression fractures by osteoporosis (OVF) is usually a diagnostic problem and coincides on the age group of metastatic vertebral compression fractures (MVF). Although radiography is the first diagnostic technique, generally is not accurate for depicting demineralization and soft tissue lesions. Magnetic resonance (MRI) is the diagnostic choice. The most relevant signs are intravertebral fluid collection or fluid signal, other vertebral deformities without oedema and older age. Among the most relevant findings for diagnosis MVF are soft tissue mass and pedicle intensity signal asymmetries. However, reproducibility of these findings in clinical practice is moderate.

Characterization of bone disease in cystic fibrosis.

With the increased life expectancy of people with cystic fibrosis (CF), clinical attention has focused on prevention and treatment of non-pulmonary comorbidities. CF-related bone disease (CFBD) is a common complication and leads to increased fracture rates. Dual energy X-ray absorptiometry (DXA) is the recommended and gold standard technique to identify and monitor bone health. However, DXA has limitations because of its two-dimensional nature. Complementary tools to DXA are available, such as trabecular bone score (TBS) and vertebral fracture assessment (VFA). Quantitative computed tomography (QCT), magnetic resonance imaging (MRI) and quantitative ultrasound (QUS) may also be useful.

Manejo de la osteoporosis en el paciente con enfermedad renal crónica (Estudio ERCOS): un desafío en la asistencia nefrológica / Osteoporosis management in patients with chronic kidney disease (ERCOS Study): A challenge in nephrological care

La valoración del riesgo de fractura del paciente con enfermedad renal crónica (ERC) ha sido incluida en el complejo Chronic Kidney Disease-Mineral and Bone Disorders (CKD-MBD) en guías nefrológicas internacionales y nacionales, sugiriéndose por primera vez la evaluación de la densidad mineral ósea (DMO) si los resultados pueden condicionar la toma de decisiones terapéuticas. Sin embargo, existe muy poca información en práctica clínica real en esta población. El objetivo principal del estudio ERC-Osteoporosis (ERCOS) es describir el perfil de los pacientes con ERC G3-5D con osteoporosis (OP) y/o fracturas por fragilidad atendidos en consultas especializadas de nefrología, reumatología y medicina interna en España. Participaron 15 centros y se incluyeron 162 pacientes (siendo en su mayoría mujeres [71,2%] posmenopáusicas [98,3%]) con una mediana de edad de 77 años. La mediana del filtrado glomerular estimado (FGe) fue de 36ml/min/1,73m2 y el 38% de pacientes incluidos estaban en diálisis. Destacamos la elevada frecuencia de fracturas por fragilidad prevalentes ([37,7%), principalmente vertebrales [52,5%] y de cadera 24,6%]), el antecedente desproporcionado de pacientes con enfermedad glomerular en comparación con series puramente nefrológicas (corticoides) y el infratratamiento para la prevención de fracturas, fundamentalmente en consultas nefrológicas. Este estudio supone una inmediata llamada a la acción con la difusión de las nuevas guías clínicas, más proactivas, y subraya la necesidad de homogeneizar el enfoque asistencial/terapéutico multidisciplinar coordinado de estos pacientes de un modo eficiente para evitar las actuales discrepancias y el nihilismo terapéutico.

Fracture risk assessment in patients with chronic kidney disease (CKD) has been included in the Chronic Kidney Disease-Mineral and Bone Disorders (CKD-MBD) complex in international and national nephrology guidelines, suggesting for the first time the assessment of bone mineral density (BMD) if the results will impact treatment decisions. However, there is very little information on actual clinical practice in this population. The main objective of the ERC-Osteoporosis (ERCOS) study is to describe the profile of patients with CKD G3-5D with osteoporosis (OP) and/or fragility fractures treated in specialized nephrology, rheumatology and internal medicine clinics in Spain. Fifteen centers participated and 162 patients (mostly women [71.2%] postmenopausal [98.3%]) with a median age of 77 years were included. Mean estimated glomerular filtration rate (eGFR) was 36ml/min/1.73m2 and 38% of the included patients were on dialysis. We highlight the high frequency of prevalent fragility fractures ([37.7%], mainly vertebral [52.5%] and hip [24.6%]), the disproportionate history of patients with glomerular disease compared to purely nephrological series (corticosteroids) and undertreatment for fracture prevention, especially in nephrology consultations. This study is an immediate call to action with the dissemination of the new, more proactive, clinical guidelines, and underlines the need to standardize a coordinated and efficient multidisciplinary care/therapeutic approach to these patients to avoid current discrepancies and therapeutic nihilism.

Composición corporal y evolución nutricional en adolescentes con anorexia nerviosa / Body composition and nutritional status changes in adolescents with anorexia nervosa

Introducción: La valoración nutricional en anorexia nerviosa (AN) incluye determinar la composición corporal y monitorizar su evolución a lo largo del periodo de tratamiento. La prueba gold standard para el estudio de la composición corporal es la absorciometría de rayos X de energía dual (DEXA), si bien la bioimpedancia eléctrica (BIA) se postula como una alternativa más accesible, barata, rápida y que no irradia. Material y métodos: Se reclutaron secuencialmente a 33 mujeres adolescentes (11,7-16,3 años) diagnosticadas de AN. Se recogieron parámetros clínicos, antropométricos y analíticos, y se realizó BIA y DEXA a la inclusión en el estudio y a la finalización del mismo con separación media de un año, durante la fase de rehabilitación nutricional. Resultados: Se objetivó mejoría significativa a nivel nutricional, reflejada en la composición corporal obtenida mediante antropometría y BIA. El ángulo de fase aumentó significativamente durante el periodo de seguimiento. Una mayor pérdida ponderal se correlacionó con la presencia de amenorrea secundaria y con una menor densidad mineral ósea en columna. Conclusiones: La BIA es una herramienta útil para la valoración y el seguimiento del estado nutricional en pacientes con AN en edad pediátrica. La DEXA sigue siendo imprescindible para conocer la afectación de la densidad mineral ósea. El papel de hormonas como la leptina está aún por determinar. (AU)

Introduction: Nutritional status assessment in anorexia nervosa (AN) includes the evaluation and monitoring of body composition throughout the treatment period. The gold standard for the study of body composition is dual-energy X-ray absorptiometry (DEXA), although electrical bioimpedance (BIA) is a more accessible, cheaper and faster method that does not involve exposure to radiation. Material and methods: We recruited 33 female adolescents with AN (age, 11.7-16.3 years) by consecutive sampling. We collected data on clinical, anthropometric and laboratory variables. Patients were assessed with BIA and DEXA at inclusion in the study and at the end of the study, with a mean duration of followup of 1 year, during the nutritional rehabilitation phase. Results: There was significant improvement in nutritional status, reflected by the body composition obtained by anthropometric measurements and BIA. The phase angle increased significantly during the followup. Greater weight loss was associated with the presence of secondary amenorrhoea and decreased bone mineral density in the spine. Conclusions: Electrical BIA is a useful tool for assessment and monitoring of nutritional status in paediatric patients with AN. Dual-energy X-ray absorptiometry continues to be essential to assess bone mineral density. The role of hormones such as leptin remains to be elucidated. (AU)

Descriptive assessment of 54 cases with complex regional pain syndrome in lower limbs / Evaluación descriptiva de 54 casos con síndrome dolo roso regional complejo en miembros inferiores

Abstract Introduction: Complex regional pain syndrome (CRPS), also known as Sudeck syndrome, is a chronic painful condition usually affecting the limbs after trauma or surgery. Its presentation is heterogeneous and its physio pathology, diagnosis and treatment remain controversial. The objective of this study was to analyze a group of patients with this rare syndrome, describing in detail the results of the dual energy X-ray absorptiometry (DXA) and the response to bisphosphonate treatment. Method: We retrospectively analyzed 54 patients with CRPS, taking into account their demographic features, inciting events and diagnostic tests. As regards treat ment, we analyzed the results and adverse events of the use of bisphosphonates Results: We found a female predominance (74%), with 55 ± 13 years. The most common inciting event was trauma (59%), followed by surgery. The difference in bone mineral density between the affected limb and the healthy one was 12 to 15%. Forty-four patients were treated with bisphosphonates (pamidronate, iban dronate, zoledronic acid) and showed a clinical im provement, mainly in terms of pain intensity. Only six patients presented with adverse events, like pseudoflu syndrome and acute phase symptoms. Conclusion: In our cohort, lower limbs CRPS pre dominantly affects middle aged women. DXA scans are tests used to quantify bone loss and the response to treatment. The use of bisphosphonates is an interest ing therapeutic option to improve clinical symptoms in most patients. Future prospective randomized studies will be needed to confirm our results.

Resumen Introducción: El síndrome doloroso regional complejo (SDRC), también conocido como síndrome de Sudeck, es una enfermedad dolorosa crónica que generalmente afecta a las extremidades luego de un trauma o cirugía. Su presentación es heterogénea y existen controversias sobre su fisiopatología, adecuado diagnóstico y trata miento. El objetivo de este trabajo es describir un grupo de pacientes con SDRC en miembros inferiores, describi endo los resultados de la densitometría mineral ósea (DMO) y la respuesta al tratamiento con bifosfonatos. Método: Analizamos retrospectivamente 54 pacientes con SDRC, teniendo en cuenta características demográ ficas, factores desencadenantes y estudios diagnósticos. En relación al tratamiento, analizamos los resultados y efectos adversos del uso de bifosfonatos. Resultados: Encontramos un predominio femenino (74%), con una edad de 55 ± 13 años. Los factores des encadenantes más comunes fueron los traumatismos (59%) y la cirugía. La diferencia de densidad mineral ósea entre el miembro comprometido y el sano fue 12 a 15%. En los 44 pacientes fueron tratados con bifosfona tos (pamidronato, ibandronato y ácido zoledrónico), su uso se asoció a mejoría clínica, especialmente del dolor. Seis pacientes tuvieron efectos adversos como sindrome pseudogripal y síntomas de fase aguda. Conclusión: En nuestra población, el SDRC de miem bros inferiores predomina en mujeres de edad media. La DMO es un método que permite cuantificar la pérdida ósea y la respuesta al tratamiento. Los bifosfonatos son una buena opción terapéutica para el control de síntomas. Son necesarios futuros estudios de naturaleza prospectiva y aleatorizada para confirmar nuestros resultados.

Elaboración de una base de referencia de composición corporal pediátrica para la provincia de Mendoza (Argentina)

R E S U M E N El objetivo fue elaborar una base de datos de referencia para composición corporal de sujetos pediátricos en la provincia de Mendoza (Argentina). Se obtuvieron datos de I4 variables de composición corporal (densidad y composición mineral ósea; masa magra y blanda; índice de masa corporal y magra, entre otros) de 198 sujetos (96 mujeres) de 4 a 19 años. Los sujetos se clasificaron en ocho grupos bienales; aquellos en etapa de transición puberal fueron clasificados según los estadios de Tanner: Las medidas se obtuvieron mediante densitometría dual de rayos-X en un equipo Lunar Prodigy DF+I6206. Para el análisis estadístico se usó Prism 5.4 en MS Win 7. Los valores de las variables analizadas aumentaron con la edad. Los valores en hombres siguen una tendencia lineal mientras en mujeres es sigmoidea, excepto el índice de masa corporal. Pacientes con igual edad, pero mayor estadio de Tanner, mostraron valores superiores de los componentes corporales. Las mujeres maduraron más tempranamente. Se concluyó que valores de las variables analizadas aumentaron con la edad y en menor medida, con las etapas de Tanner Los cambios son más precoces en mujeres y siguen diferentes cursos temporales en ambos sexos.

The objective was to develop a reference database for body composition of pediatric subjects in the province of Mendoza (Argentina). Data on I4 body composition variables (bone mineral density and composition; lean and soft mass; lean and body mass index, among others) were obtained from I98 subjects (96 women) aged 4 to 19 years. Subjects were classified into eight biennial groups; those in the pubertal transition stage were classified according to the Tanner stages. Measurements were obtained by dual X-ray densitometry on a Lunar Prodigy DF+I6206 instrument. For the statistical analysis, Prism 5.4 in MS Win 7 was used. The values of the variables analyzed increased with age. The values i n men follow a linear trend while in women it is sigmoid, except for the body mass index. Patients with the same age, but higher Tanner stage, showed higher values of body components. Women matured earlier It was concluded that the values of the variables analyzed increased with age and, to a lesser extent, with the Tanner stages. The changes are earlier and follow different time courses in women than in men.

Objetivo: Evaluar la densitometría corneal en pacientes con queratocono. Métodos: Se realizó un estudio observacional descriptivo de corte transversal que incluyó 90 pacientes con queratocono (grupo de estudio) y 30 estudiantes con córneas aparentemente sanas (grupo control), que asistieron a la consulta de córnea del Instituto Cubano de Oftalmología Ramón Pando Ferrer, entre mayo del 2018 y junio del 2019. Se seleccionó el ojo derecho de cada caso. Se analizaron densitometría corneal con el tomógrafo corneal Pentacam AXL. Resultados: La densitometría fue mayor en el queratocono respecto a la córnea aparentemente sana, de 0 a 2 mm, en la capa anterior, central, y posterior, respectivamente (p < 0,001). La densitometría aumentó en los 0 a 2 mm en la capa anterior en el grupo moderado y en el grupo avanzado (p < 0,001), y entre los 2-6 mm en la capa central, de 10,86 ± 0,54 en el control, en el queratocono avanzado a 12,35 ± 1,16 y en el moderado a 12,16 ± 1,45 (p < 0,001). La densitometría aumentó en el avanzado de 27,64 ± 3,81, de 22,77 ± 2,14 en el leve, y de 24,04 ± 2,83 en el moderado y en los 0-2 mm, en la capa anterior. Conclusiones: La densitometría es mayor en la córnea queratocónica respecto a la córnea aparentemente sana, además que se incrementa al aumentar la gravedad del queratocono en el área central(AU)

Objective: To evaluate corneal densitometry in patients with keratoconus. Methods: A cross-sectional descriptive observational cross-sectional study was performed including 90 patients with keratoconus (study group) and 30 students with apparently healthy corneas (control group), who attended the cornea consultation at the Cuban Institute of Ophthalmology Ramón Pando Ferrer, between May 2018 and June 2019. The right eye of each case was selected. Corneal densitometry was analyzed with the Pentacam AXL corneal tomographer. Results: Densitometry was higher in keratoconus relative to apparently healthy cornea, from 0 to 2 mm, in the anterior, central, and posterior layer, respectively (p < 0.001). Densitometry increased in the 0 to 2 mm in the anterior layer in the moderate group and in the advanced group (p < 0.001), and between 2-6 mm in the central layer, from 10.86 ± 0.54 in the control, in the advanced keratoconus to 12.35 ± 1.16 and in the moderate to 12.16 ± 1.45 (p < 0.001). Densitometry increased in advanced from 27.64 ± 3.81, from 22.77 ± 2.14 in mild, and from 24.04 ± 2.83 in the moderate and 0-2 mm, in the anterior layer. Conclusions: Densitometry is higher in the keratoconic cornea with respect to the apparently healthy cornea, moreover it increases with increasing severity of keratoconus in the central area(AU)

Hipertensión arterial asociada a osteoporosis en pacientes mujeres del hospital del Seguro Social, Trujillo

Objetivo: Determinar si la hipertensión arterial se encuentra asociada a osteoporosis en pacientes mujeres del Hospital I del Seguro Social en Trujillo. Materiales y métodos: El tipo de estudio realizado fue observacional, analítico y transversal. Participaron 351 pacientes mujeres atendidas en un consultorio del Servicio de Medicina Interna del Hospital I de Florencia de Mora de EsSalud en Trujillo durante el periodo 2016-2019. Según los criterios de selección, se dividieron en dos grupos: 175 pacientes con hipertensión arterial y 176 pacientes sin hipertensión arterial, para demostrar el número de pacientes con osteoporosis. Los datos se analizaron mediante la prueba chi cuadrado de Pearson con el paquete SPSS 26.0, para realizar el análisis estadístico, y así presentar los resultados obtenidos en gráficos y tablas, lo cual se realizó en Excel Windows 10. Resultados: Se encontró que la prevalencia de osteoporosis con hipertensión arterial fue del 31,4 %; la osteoporosis sin hipertensión arterial, 1,7 %. Esto evidencia que la prevalencia de osteoporosis en mujeres con hipertensión arterial es estadísticamente significativa (p < 0,001) respecto a las mujeres sin hipertensión arterial. En cuanto al análisis de las variables intervinientes, aquellas que fueron estadísticamente significativas fueron la edad (p < 0,001), el colesterol (p < 0,001) y el café (p < 0,001). Las variables como diabetes mellitus 2, sexo, obesidad, anemia, triglicéridos y tabaco no fueron estadísticamente significativas. Conclusiones: La hipertensión arterial sí se encuentra asociada a osteoporosis, así como las variables intervinientes como edad, colesterol y café, ya que fueron estadísticamente significativas.

Materials and methods: An observational, analytical and cross-sectional study, which included 351 female patients treated in the Internal Medicine Unit of EsSalud Hospital I Florencia de Mora, Trujillo, from 2016 to 2019. According to the screening criteria, patients were divided into two groups-175 with hypertension and 176 without hypertension-to determine the number of patients with osteoporosis. The data was analyzed with Pearson's chi-square test using IBM SPSS Statistics V26 to perform the statistical analysis and present the results in graphs and tables in Microsoft Excel Windows 10. Results: It was found that the prevalence of osteoporosis with hypertension accounted for 31.4 %, while that of osteoporosis without hypertension was 1.7 %. This shows that the prevalence of osteoporosis in women with hypertension is statistically significant (p < 0.001) with respect to women without hypertension. Regarding the analysis of the intervening variables, age (p < 0.001), cholesterol (p < 0.001) and coffee (p < 0.001) were statistically significant. Variables such as type 2 diabetes mellitus, sex, obesity, anemia, triglycerides and smoking were not statistically significant. Conclusions: Hypertension is associated with osteoporosis as well as with the intervening variables age, cholesterol and coffee, as they were statistically significant.

Assessment of body composition by whole-body densitometry: what radiologists should know / Avaliação da composição corporal pela densitometria de corpo inteiro: o que os radiologistas precisam saber

Abstract The analysis of body composition is a fundamental part of a nutritional status assessment, and the use of diagnostic imaging methods has been increasingly required for an adequate characterization of the lean body mass and fat mass. Body composition measurements are useful in evaluating the effectiveness of nutritional interventions and monitoring changes associated with aging and chronic diseases. Whole-body densitometry using dual-energy X-ray absorptiometry (DEXA) is one of the most widely used methods in clinical practice, allowing highly accurate assessment of the bone mineral content, lean body mass, and fat mass. Although a DEXA examination provides a lot of information, there is still no universal standardization of the parameters to be included in radiology reports. The aim of this study was to review the most relevant information for assessing body composition by whole-body densitometry.

Resumo A análise da composição corporal é parte fundamental de uma avaliação nutricional, em que a utilização de métodos diagnósticos por imagem tem sido cada vez mais requisitada para uma adequada caracterização da massa magra e massa gorda corporal. Medidas de composição corporal são úteis em avaliar a eficácia das intervenções nutricionais e monitorar as mudanças associadas ao envelhecimento e condições de doenças crônicas. A densitometria de corpo inteiro utilizando a técnica de absorciometria de dupla energia (DEXA) é um dos métodos mais utilizados na prática clínica, que permite avaliação com elevada acurácia do conteúdo mineral ósseo, da gordura corporal e da massa magra. Este exame fornece grande quantidade de informações, no entanto, ainda não existe uma padronização universal de quais parâmetros devem ser incluídos nos relatórios radiológicos. O objetivo deste trabalho é revisar as informações mais relevantes para avaliação da composição corporal fornecidas pela densitometria de corpo inteiro.

Pico de Massa Óssea e Níveis de Exercício Físico em Estudantes Universitários / Peak Bone Mass and Exercise Levels: Comparison between Physical Education and Medical Students

Introdução: Promover um adequado pico de massa óssea (PMO) é uma estratégia de prevenção para a osteoporose. Os estudantes universitários estão em idade de aquisição de massa óssea suscetível à influência dos hábitos do estilo de vida, incluindo a prática de exercícios físicos. Assim sendo, este estudo objetivou avaliar a massa óssea em universitários com diferentes estilos de vida. Métodos: Foram avaliados 142 estudantes, sendo 74 de Medicina (MED) e 68 de Educação Física (EF), com idade média de 22 anos. As variáveis do estudo foram obtidas por meio de anamnese densitométrica. A densidade mineral óssea (DMO) da coluna lombar, corpo inteiro, colo do fêmur e fêmur total foi medida por absorciometria de dupla emissão de raios X. Resultados: Não houve diferenças em relação à idade, sexo, IMC e ingestão de cálcio entre os grupos. Os estudantes de EF praticam mais exercícios que os de MED (481 vs. 128 min/semana). A frequência de exercício físico suficiente (> 150 min/semana) foi maior no grupo EF (91,2% vs. 40,5%; p <0,01). Exercícios que influenciam a DMO foram mais frequentes entre os estudantes de EF (91,2% vs. 63,5%; p <0,01). Baixo PMO foi mais frequente no grupo MED (52,7 vs. 14,7; p<0,01). Observou-se correlação positiva entre a quantidade semanal de exercício físico e DMO. Conclusão: Maiores taxas de prática de exercícios físicos foram associadas com melhor PMO em estudantes do curso de Educação Física.

Introduction: Promoting adequate peak bone mass (PBM) is a prevention strategy for osteoporosis. College students are at the age of bone mass acquisition susceptible to the influence of lifestyle habits, including exercise. Therefore, this study aimed to evaluate bone mass in college students with different lifestyles. Methods: We evaluated 142 students, 74 from Medicine (MED) and 68 from Physical Education (PE), with a mean age of 22 years. The study variables were obtained by densitometric anamnesis. Bone mineral density (BMD) of the lumbar spine, whole body, femoral neck, and total femur was measured by dual emission X-ray absorptiometry. Results: There were no differences in age, gender, BMI, and calcium intake between the groups. PE students exercised more than MED students (481 vs. 128 min/week). The frequency of sufficient exercise (> 150 min/week) was higher in the EF group (91.2% vs. 40.5%; p <0.01). Exercise influencing BMD was more frequent among EF students (91.2% vs. 63.5%; p <0.01). Low PBM was more frequent in the MED group (52.7 vs. 14.7; p<0.01). The study showed a positive correlation between the weekly amount of exercise and BMD. Conclusion: Higher exercise rates were associated with better PBM in physical education students.

Assessment of body composition in cystic fibrosis: agreement between skinfold measurement and densitometry / Evaluación de la composición corporal en adultos con fibrosis quística: concordancia entre la densitometría y la antropometría

Introduction: few studies have evaluated body composition (BC) through different techniques, and the degree of agreement between them in adults with cystic fibrosis (CF). Objectives: to describe BC using techniques to assess nutritional status and to test their concordance in CF. Methods: a cross-sectional study in CF patients in a clinically stable situation. Nutritional assessment was performed using skinfold measurement (SM) and densitometry (DXA). Fat-free mass index (FFMI) was also determined. The diagnosis of malnutrition was established if body mass index (BMI) < 18.5 kg/m2. Fat-free mass (FFM) malnutrition was diagnosed when FFMI was < 17 kg/m2 in males and < 15 kg/m2 in females (FFMI: fat-free mass in kg/height in m2). Results: forty-one patients were studied (twenty-two females, 53.7 %); median age was 29.8 (interquartile range, 20.9-33.7); BMI was 21.6 (19.8-23.0). Only four (9.8 %) patients had a BMI < 18.5. By DXA, FFM (kg) results were: median, 52.8 (47.8-56.9) with FFMI of 17.9 (16.7-19.3) in males and 36.7 (33.1-38.9) in females, FFMI of 14.7 (14.2-15.8). Twenty (48.6 %) patients presented FFM malnutrition, with 16.7 % of males and 59.1 % of females being affected. By SM, the FFMI was 18.7 (17.2-20.0) in males and 14.9 (14.2-15.8) in females; moreover, sixteen (39.1 %) patients presented malnutrition of FFM, with 20.8 % of males and 61.8 % of females being affected. For FFM (kg), high concordance was obtained between SM and DXA (intraclass correlation coefficient of 0.950); likewise when they were compared by applying the ESPEN criteria for FFM malnutrition. However, when the techniques were compared to classify malnutrition according to FFMI, the kappa coefficient was only moderate (k = 0.440). The mean difference between FFM by DXA and SM was +1.44 ± 0.62 kg in favor of SM, with greater dispersion as FFM increased. Conclusions: the prevalence of FFM malnutrition is high in adult CF patients, despite a normal BMI, especially in females (AU)

Introducción: pocos estudios han evaluado la composición corporal (BC) mediante diferentes técnicas y el grado de concordancia entre ellas en adultos con fibrosis quística (FQ). Objetivos: describir la BC mediante técnicas de evaluación Nutricional y comprobar su concordancia en la FQ. Métodos: estudio transversal de adultos con FQ en situación de estabilidad clínica. La evaluación Nutricional se realizó mediante medición de pliegues cutáneos (SM) y densitometría (DXA). También se determinó el índice de masa libre de grasa (FFMI). El diagnóstico de desnutrición se estableció si el índice de masa corporal (IMC) era < 18,5 kg/m2. Se diagnosticó desnutrición por masa libre de grasa (FFM) cuando el FFMI era < 17 kg/m2 en los hombres y < 15 kg/m2 en las mujeres (FFMI: masa libre de grasa en kg/estatura en m2). Resultados: se estudiaron cuarenta y un pacientes (veintidós mujeres (53,7 %), con una edad media de 29,8 años (rango intercuartílico, 20,9-33,7) y un IMC de 21,6 (19,8-23,0). Solo cuatro (9,8 %) pacientes tenían un IMC < 18,5. Mediante DXA, los resultados de FFM (kg) fueron (mediana y RIC): 52,8 (47,8-56,9) con FFMI de 17,9 (16,7-19,3) en los varones y 36,7 (33,1-38,9) en las mujeres con FFMI de 14,7 (14,2-15,8). Veinte (48,6 %) pacientes presentaban desnutrición del FFM, con el 16,7 % de varones y el 59,1 % de mujeres afectados. Mediante el SM, el FFMI fue de 18,7 (17,2-20,0) en los varones y de 14,9 (14,2-15,8) en las mujeres; además, dieciséis (39,1 %) pacientes presentaban malnutrición del FFMI, con el 20,8 % de varones y el 61,8 % de mujeres afectados. En el caso de la FFM (kg), se obtuvo una alta concordancia entre el SM y la DXA (coeficiente de correlación intraclase de 0,950); igualmente cuando se compararon las técnicas aplicando los criterios ESPEN para la desnutrición de la FFM. Sin embargo, cuando se compararon las técnicas para clasificar la malnutrición según el FFMI, el coeficiente kappa fue solo moderado (coeficiente kappa = 0,440) (AU)

Factores de riesgo y prevalencia de osteopenia y osteoporosis en mujeres posmenopáusicas diagnosticadas por densitometría ósea / Risk factors and prevalence of osteopenia and osteoporosis in postmenopausal women diagnosed by bone densitometry

Resumen Objetivo: Determinar la prevalencia de la osteoporosis en mujeres costarricenses posmenopáusicas, atendidas en el Hospital San Juan de Dios de la Caja Costarricense del Seguro Social, y relacionar con características clínicas y de estilo de vida. Métodos. Estudio transversal. Se analizó un total de 923 estudios de densitometría ósea de mujeres con edad entre los 45 y 80 años, en etapa posmenopáusica; se registró un valor de T-score obtenido por densitometría ósea para columna lumbar y cadera; se documentó las variables como la edad, el índice de masa corporal, tabaquismo y otros reconocidos factores de riesgo; se estimó la prevalencia y se analizó la relación con los factores. Resultados. A partir de 923 estudios y los factores de riesgo comúnmente asociados con la enfermedad, fueron estadísticamente significativos los siguientes: la edad (p<0,001), la edad en la menarquia (p = 0,001), la cantidad de años transcurridos desde la menopausia (p<0,001) y el antecedente familiar de fractura de cadera (p = 0,01). Otros factores no resultaron significativos. Conclusiones. Para la población estudiada, se demostró una prevalencia de 47% para osteopenia y de 39% para osteoporosis en mujeres posmenopáusicas. No se logró establecer una relación en las variables de estilo de vida, tales como tabaquismo, alcoholismo, actividad física y consumo de lácteos. Se deben realizar otras investigaciones con un mayor control sobre estas variables para conocer su riesgo relacionado con la enfermedad.

Abstract Aim: To determine the prevalence of osteoporosis in postmenopausal Costa Rican women treated at the San Juan de Dios Hospital of the Costa Rican Social Security Fund, and relate it to clinical and lifestyle characteristics. Methods. Transversal study. A total of 923 bone densitometry studies of postmenopausal women aged between 45 and 80 years were analyzed; A T-score value obtained by bone densitometry was recorded for the lumbar spine and hip; variables such as age, bodymass index, smoking, and other recognized risk factors were documented; the prevalence was estimated and the relationship with the factors was analyzed. Results. From 923 studies and risk factors commonly associated with the disease, the following were statistically significant: age (p<0.001), age at menarche (p = 0.001), number of years since menopause (p<0.001) and family history of hip fracture (p = 0.01). Other factors were not significant. Conclusions. For the population studied, a prevalence of 47% for osteopenia and 39% for osteoporosis in postmenopausal women was demonstrated. It was not possible to establish a relationship in lifestyle variables, such as smoking, alcoholism, physical activity and dairy consumption. Other investigations with greater control over these variables should be carried out to know their risk related to the disease.

Assessment of body composition in cystic fibrosis: agreement between skinfold measurement and densitometry.

Introduction: Introduction: few studies have evaluated body composition (BC) through different techniques, and the degree of agreement between them in adults with cystic fibrosis (CF). Objectives: to describe BC using techniques to assess nutritional status and to test their concordance in CF. Methods: a cross-sectional study in CF patients in a clinically stable situation. Nutritional assessment was performed using skinfold measurement (SM) and densitometry (DXA). Fat-free mass index (FFMI) was also determined. The diagnosis of malnutrition was established if body mass index (BMI) < 18.5 kg/m2. Fat-free mass (FFM) malnutrition was diagnosed when FFMI was < 17 kg/m2 in males and < 15 kg/m2 in females (FFMI: fat-free mass in kg/height in m2). Results: forty-one patients were studied (twenty-two females, 53.7 %); median age was 29.8 (interquartile range, 20.9-33.7); BMI was 21.6 (19.8-23.0). Only four (9.8 %) patients had a BMI < 18.5. By DXA, FFM (kg) results were: median, 52.8 (47.8-56.9) with FFMI of 17.9 (16.7-19.3) in males and 36.7 (33.1-38.9) in females, FFMI of 14.7 (14.2-15.8). Twenty (48.6 %) patients presented FFM malnutrition, with 16.7 % of males and 59.1 % of females being affected. By SM, the FFMI was 18.7 (17.2-20.0) in males and 14.9 (14.2-15.8) in females; moreover, sixteen (39.1 %) patients presented malnutrition of FFM, with 20.8 % of males and 61.8 % of females being affected. For FFM (kg), a high concordance was obtained between SM and DXA (intraclass correlation coefficient of 0.950); likewise when they were compared by applying the ESPEN criteria for FFM malnutrition. However, when the techniques were compared to classify malnutrition according to FFMI, the kappa coefficient was only moderate (k = 0.440). The mean difference between FFM by DXA and SM was +1.44 ± 0.62 kg in favor of SM, with greater dispersion as FFM increased. Conclusions: the prevalence of FFM malnutrition is high in adult CF patients, despite a normal BMI, especially in females. Notwithstanding the good statistical agreement between SM and DXA, concordance was moderate. Therefore, DXA remains the technique of choice, and SM may be used when the former is not available.

El diagnóstico de desnutrición se estableció si el índice de masa corporal era < 18,5 kg/m2. Se diagnosticó desnutrición por masa libre de grasa (FFM) cuando el FFMI era < 17 kg/m2 en 4 hombres y < 15 kg/m2 en mujeres (FFMI: masa libre de grasa en kg/estatura en m2). Resultados: se estudiaron 41 pacientes (22 mujeres (53,7 %), con una edad media de 29,8 años (rango intercuartílico, 20,9-33,7) e IMC de 21,6 (19,8-23,0). Solo 4 (9,8 %) pacientes tenían un IMC < 18,5.

Sin embargo, cuando se compararon las técnicas para clasificar la malnutrición según el FFMI, el coeficiente kappa fue solo moderado (coeficiente kappa = 0,440). La diferencia media entre el FFM por DXA y el SM fue de +1,44 ± 0,62 kg a favor del SM, con mayor dispersión a medida que aumenta el FFM. Conclusiones: la prevalencia de la malnutrición por FFM es elevada en pacientes adultos con FQ, a pesar de presentar un IMC normal, especialmente en el caso de las mujeres. A pesar de existir una buena correlación estadística entre el SM y la DXA, la concordancia fue moderada. Por lo tanto, la DXA sigue siendo la técnica de elección y el SM puede ser una alternativa cuando la DXA no esté disponible.
