[Gastrocolic fistula as infrequent cause of chronic diarrhea in a patient with percutaneous radiological gastrostomy]. / Fístula gastrocólica como causa infrecuente de diarrea persistente en un paciente portador de gastrostomía radiológica percutánea.

Introduction: Introduction: gastrocolic fistula is an infrequent but severe complication of percutaneous gastrostomy. Clinical suspicion in the presence of chronic diarrhea of unknown etiology manifesting after percutaneous radiological gastrostomy (PRG) tube replacement is key to early detection and treatment. Case report: we report the case of a patient with PRG that began with chronic diarrhea after tube replacement and developed severe malnutrition. Initial treatment was not effective, studies were extended with the finding of this complication in a CT image. The use of this tube was discontinued with resolution of diarrhea and a favorable nutritional outcome. Discussion: this case report shows the importance of considering gastrocolic fistula in the differential diagnosis of persistent diarrhea in a patient with a gastrostomy tube.

Introducción: Introducción: la fístula gastrocólica supone una complicación infrecuente pero potencialmente grave de las sondas de gastrostomía. La sospecha clínica ante una diarrea de origen incierto que comienza tras el recambio de la sonda es clave para la detección y el tratamiento precoces. Caso clínico: se presenta el caso de un paciente portador de gastrostomía radiológica percutánea (PRG) que comienza con diarrea persistente tras el primer recambio de la sonda y desnutrición grave secundaria. Tras el fracaso de las medidas terapéuticas iniciales se amplían los estudios, con hallazgo de esta complicación en la imagen de TC. Se suspende el uso de esta sonda con resolución de la diarrea y evolución nutricional favorable. Discusión: este caso pone de manifiesto la importancia de incluir la fístula gastrocólica en el diagnóstico diferencial de la diarrea persistente en un paciente portador de sonda de gastrostomía.

Ultrasound Cut-Off Values for Rectus Femoris for Detecting Sarcopenia in Patients with Nutritional Risk.

BACKGROUND: A nationwide, prospective, multicenter, cohort study (the Disease-Related caloric-protein malnutrition EChOgraphy (DRECO) study) was designed to assess the usefulness of ultrasound of the rectus femoris for detecting sarcopenia in hospitalized patients at risk of malnutrition and to define cut-off values of ultrasound measures. METHODS: Patients at risk of malnutrition according to the Malnutrition Universal Screening Tool (MUST) underwent handgrip dynamometry, bioelectrical impedance analysis (BIA), a Timed Up and Go (TUG) test, and rectus femoris ultrasound studies. European Working Group on Sarcopenia in Older People (EWGSOP2) criteria were used to define categories of sarcopenia (at risk, probable, confirmed, severe). Receiver operating characteristic (ROC) and area under the curve (AUC) analyses were used to determine the optimal diagnostic sensitivity, specificity, and predictive values of cut-off points of the ultrasound measures for the detection of risk of sarcopenia and probable, confirmed, and severe sarcopenia. RESULTS: A total of 1000 subjects were included and 991 of them (58.9% men, mean age 58.5 years) were evaluated. Risk of sarcopenia was detected in 9.6% patients, probable sarcopenia in 14%, confirmed sarcopenia in 9.7%, and severe sarcopenia in 3.9%, with significant differences in the distribution of groups between men and women (p < 0.0001). The cross-sectional area (CSA) of the rectus femoris showed a significantly positive correlation with body cell mass of BIA and handgrip strength, and a significant negative correlation with TUG. Cut-off values were similar within each category of sarcopenia, ranging between 2.40 cm2 and 3.66 cm2 for CSA, 32.57 mm and 40.21 mm for the X-axis, and 7.85 mm and 10.4 mm for the Y-axis. In general, these cut-off values showed high sensitivities, particularly for the categories of confirmed and severe sarcopenia, with male patients also showing better sensitivities than women. CONCLUSIONS: Sarcopenia in hospitalized patients at risk of malnutrition was high. Cut-off values for the better sensitivities and specificities of ultrasound measures of the rectus femoris are established. The use of ultrasound of the rectus femoris could be used for the prediction of sarcopenia and be useful to integrate nutritional study into real clinical practice.

Nutritional Iodine Status in Pregnant Women from Health Area IV in Asturias (Spain): Iodised Salt Is Enough.

BACKGROUND: Iodine deficiency during pregnancy may have adverse effects on the neurodevelopment of the foetus. Recent studies of pregnant women in Asturias (Spain) indicate that nutritional iodine levels are sufficient. The objective of this study was to confirm the appropriate nutritional iodine status and to analyse the influence of the ingestion of iodine on maternal urinary iodine concentration (UIC) and thyroid function. METHODS: An observational study was carried out between May and June 2017 on women in the first trimester of pregnancy from Health Area IV in Asturias. The women completed a questionnaire related to their consumption of iodine and samples were taken to analyse UIC and thyroid function. RESULTS: Three hundred and eighteen pregnant women were involved. Of these, 51.10% used iodised salt, 48.90% consumed ≥ 2 servings of dairy products daily and 87.08% took iodine supplements. The median UIC was 171.5 µg/L (116-265 µg/L) and 60.41% of women had UIC ≥ 150 µg/L. Multivariate logistic regression analysis demonstrated that iodised salt had a protective effect on UIC < 150 µg/L (odds ratio (OR) 0.404 (0.237-0.683), p = 0.001), but not iodine supplements (OR 0.512 (0.240-1.085), p = 0.080). The average level of thyroid stimulating hormone (TSH) was 2.26 ± 0.94 mIU/L; 68.40% of pregnant women taking iodine supplements had TSH < 2.5 mIU/L compared to 30.00% of those who were not taking supplements (p = 0.031). CONCLUSIONS: The pregnant women in our health area are maintaining appropriate nutritional iodine levels. The consumption of iodised salt protects against iodine deficiency; thus, iodine supplements should be taken on an individualised basis.

SeDREno study - prevalence of hospital malnutrition according to GLIM criteria, ten years after the PREDyCES study.

INTRODUCTION: Background & aims: the last large multicenter study on disease-related malnutrition (DRM) in Spain (the PREDyCES study) showed a 23.7 % prevalence of malnutrition, according to the Nutritional Risk Screening (NRS-2002) tool. The main objective of the SeDREno study was to assess the prevalence of hospital malnutrition upon admission, according to GLIM criteria, ten years later. Methods: a cross-sectional, observational, multicenter study in standard clinical practice, conducted in 17 hospitals during a period of five to seven days. Patients were initially screened using the Malnutrition Universal Screening Tool (MUST), and then assessed using the GLIM criteria for diagnosis and severity grading. Results: a total of 2,185 patients, 54.8 % males, mean age 67.1 (17.0) years (50.2 % aged ≥ 70 years), were evaluated. Malnutrition was observed in 29.7 % of patients according to GLIM criteria (12.5 % severe, 17.2 % moderate). In patients ≥ 70 years malnutrition was observed in 34.8 %. The clinical conditions significantly associated with a higher prevalence of malnutrition were dysphagia (47.6 %), cognitive impairment (43.4 %), cancer (39.1 %), gastrointestinal disease (37.7 %), diabetes (34.8 %), and cardiovascular disease (33.4 %). The multivariate analysis revealed that gender, BMI, diabetes, cancer, gastrointestinal disorders, and polypharmacy were the main independent factors associated with DRM. Malnutrition was associated with an increase in length of hospital stay and death (p < 0.001). Conclusions: DRM in admitted patients has increased in Spain in the last 10 years paralleling ageing of the population. In the SeDREno study almost one in three patients are malnourished. A systematic assessment of nutritional status allows early detection and implementation of nutritional interventions to achieve a better clinical outcome.

INTRODUCCIÓN: Antecedentes y objetivos: el último gran estudio multicéntrico sobre desnutrición relacionada con la enfermedad (DRE) en España (el estudio PREDyCES) mostró una prevalencia de desnutrición del 23,7 % según la herramienta Nutritional Risk Screening (NRS-2002). El principal objetivo del estudio SeDREno fue evaluar la prevalencia de la desnutrición hospitalaria al ingreso según los criterios GLIM diez años después. Métodos: estudio transversal, observacional, multicéntrico, según la práctica clínica estándar, realizado en 17 hospitales durante un período de cinco a siete días. Los pacientes fueron evaluados inicialmente con la herramienta de detección universal de desnutrición (MUST) y luego con los criterios GLIM para el diagnóstico de DRE y la clasificación de la gravedad. Resultados: se evaluaron 2185 pacientes, con un 54,8 % de varones una edad media de 67,1 (17,0) años (50,2 % ≥ 70 años). Se observó desnutrición en el 29,7 % de los pacientes según los criterios GLIM (12,5 % grave, 17,2 % moderada). Entre los pacientes ≥ 70 años se observó desnutrición en el 34,8 %. Las condiciones clínicas asociadas significativamente con una mayor prevalencia de desnutrición fueron la disfagia (47,6 %), el deterioro cognitivo (43,4 %), el cáncer (39,1 %), las enfermedades gastrointestinales (37,7 %), la diabetes (34,8 %) y la patología cardiovascular (33,4 %). El análisis multivariante reveló que el sexo, el IMC, la diabetes, el cáncer, los trastornos gastrointestinales y la polimedicación eran los principales factores independientes asociados a la DRE. La desnutrición se asoció a un aumento de la duración de la estancia hospitalaria y la muerte (p < 0,001). Conclusiones: la DRE en pacientes ingresados ha aumentado en España en los últimos 10 años en paralelo con el aumento del envejecimiento de la población. En el estudio SeDREno, casi uno de cada tres pacientes está desnutrido. La evaluación sistemática del estado nutricional permite la detección e implementación precoces de intervenciones nutricionales para lograr un mejor resultado clínico.

Incidence of cardiovascular events and changes in the estimated risk and treatment of familial hypercholesterolemia: the SAFEHEART registry.

INTRODUCTION AND OBJECTIVES: The SAFEHEART study was designed to analyze the situation of familial heterozygous hypercholesterolemia (FHH) and improve knowledge of this disease in Spain. Our objective was to determine the incidence rate of cardiovascular events, the estimated risk of developing an event and its modification, the use of lipid-lowering treatment, and the achievement of low-density lipoprotein cholesterol targets in patients with FHH. METHODS: SAFEHEART is a prospective, open, multicenter, nationwide cohort study, with long-term protocol-based follow-up in a population of individuals with molecularly-characterized FHH. We analyzed patients older than 18 years with complete follow-up. RESULTS: We included 2648 patients with FHH. The median follow-up was 6.6 (4.8-9.7) years. The overall incidence rate of cardiovascular events was 1.3 events/100 patient-years. After the follow-up, the 10-year estimated risk of developing a cardiovascular event was reduced from 1.6% to 1.3% (P <.001). In the last follow-up, 20.6% and 22.2% of the patients in primary and secondary prevention achieved low-density lipoprotein cholesterol values <100mg/dL and <70mg/dL, respectively. CONCLUSIONS: This study was performed in the largest population of patients with FHH in Spain. We identified the incidence rate of cardiovascular events, the estimated risk of developing a cardiovascular event and its modification, the achievement of low-density lipoprotein cholesterol targets, and the therapeutic management in this population. Although the cardiovascular risk of FHH is high, appropriate treatment reduces the likelihood of an event. CLINICAL TRIAL REGISTRATION: http://www.clinicaltrials.gov. Identifier: NCT02693548.

Iodine nutritional status in Asturian schoolchildren. / Estado nutricional de yodo en la población escolar asturiana.

INTRODUCTION: Iodine deficiency is a public health problem, and iodine nutritional status should therefore be regularly measured. OBJECTIVE: To ascertain iodine nutritional status in Asturias and its relation to use of iodized salt and to other sociodemographic and nutritional parameters. MATERIAL AND METHODS: A descriptive, observational study was conducted in a random sample of schoolchildren aged 5 to 14 years, in whom urinary iodine levels were measured by high-performance liquid chromatography. Families completed a survey on use of iodized salt, consumption of dairy products and fish, and sociodemographic data. RESULTS: The study sample consisted of 705 schoolchildren (51.1% females) with a mean age of 9.9 years (SD 2.6). In a total of 620 valid measurements, mean urinary iodine level was 204.1 µg/L (SD 120.6), while the median value was 180.7 µg/L (P25-P75: 124-252.3 µg/L, interquartile range 128.3 µg/L). Urinary iodine levels were <100 µg/L in 16.6% of children, and very low (<20 µg/L) in 0.2%. Iodized salt was used in 69.3% of all households, and in all school canteens. Consumption of dairy products was significantly associated to urinary iodine levels (P<.0005). CONCLUSION: Iodine nutrition of Asturian schoolchildren is adequate, although the target of use of iodized salt in 90% of households is still far away. Adequate iodine nutrition may be due to other sources, such as dairy products. Public health campaigns are required to promote iodized salt consumption. Regular assessment of iodine nutritional status is also needed.
