Impact of triple transmembrane regulator therapy on glucose metabolism in cystic fibrosis related diabetes during clinical practice.

AIMS: To evaluate the impact of elexacaftor/tezacaftor/ivacaftor (ETI) therapy on Cystic Fibrosis Related Diabetes (CFRD) glycemic control and insulin treatment in patients with CFRD during clinical practice. METHODS: We carried out a retrospective observational study of 23 adult patients with CFRD who started treatment with ETI. They had, at least, one F508del mutation. Data were collected before ETI initiation and 3, 6, and 12 months after. RESULTS: Glycemic control measured by HbA1c significantly improved by 0.3 % (0.1-0.5) after 3 months of ETI therapy (p = 0.004) and kept this improvement during follow-up (p < 0.001). The proportion of patients needing multiple daily injections of insulin was reduced by 16 % (p = 0.023). Total daily insulin dose dropped by 0.12 (0.05-0.18) UI/kg/day (p < 0.001). Data derived from Flash Continuous Glucose Monitoring (CGM) for patients treated with insulin stayed unchanged after insulin reduction, except for a significant 8 % (0.3-15.6) increase in the Time In Tight Range (TITR) between 70 and 140 mg/dL (p = 0.043). CONCLUSION: ETI therapy impacted CFRD in clinical practice reducing insulin needs and improving glycemic control measured by HbA1c and CGM. The improvements can be observed from the first 3 months of treatment.

Valoración nutricional por ecografía del recto femoral y el tejido adiposo preperitoneal como predictores del riesgo de complicaciones del paciente hospitalizado / Nutritional assessment by ultrasound of the rectus femoris and preperitoneal adipose tissue as predictors of hospitalized patient complications

Introducción La desnutrición y la sarcopenia se asocian al aumento del riesgo de eventos adversos y peor evolución en los pacientes hospitalizados. La ecografía constituye una herramienta de utilidad en la evaluación de la composición corporal. Pacientes y métodos Se reclutaron 23 pacientes ingresados en una planta de hospitalización. Se recogieron las variables ecográficas del tejido muscular y tejido adiposo, así como su variación durante el ingreso. Correlacionándose con datos antropométricos, clínicos y analíticos. Resultados Observamos una correlación de las mediciones ecográficas con la duración de la hospitalización (grasa preperitoneal máxima: −0,585, grosor del recto femoral [RF]: −0,539, área del RF: −0,540), la fragilidad (RF: −0,599) y la dependencia (RF: 0,628). La capacidad de contracción del RF se correlacionó con el ejercicio semanal reportado (0,642). Conclusión El grosor del RF y de la grasa preperitoneal se correlacionan con el número de días de ingreso y la capacidad funcional, erigiéndose como variables pronósticas (AU)

Introduction Malnutrition and sarcopenia are associated with increased risk of adverse events and worse outcome in hospitalised patients. Ultrasonography is a useful tool in the assessment of body composition. Patients and methods Twenty-three patients admitted to a hospital ward were recruited. Ultrasonographic variables of muscle tissue and adipose tissue were collected, as well as their variation during admission. These were correlated with anthropometric, clinical and analytical data. Results We observed a correlation of ultrasound measurements with length of hospitalisation (maximum preperitoneal fat −0.585, rectus femoris thickness [RF] −0.539, RF area −0.540), frailty (RF −0.599) and dependency (RF 0.628). RF contractile capacity correlated with reported weekly exercise (0.642). Conclusion RF and preperitoneal fat thickness correlate with the number of days of admission and functional capacity, emerging as prognostic variables (AU)

El consumo regular de un caldo funcional enriquecido con fosfofructooligosacáridos aumenta los niveles de las hormonas relacionadas con la saciedad en las personas sanas. Ensayo clínico aleatorizado y controlado / Regular consumption of a functional broth enriched with phospho-fructooligosaccharides increases the levels of hormones related to satiety in healthy people. A randomized, controlled clinical trial

Introducción: el exceso de peso representa un problema de salud pública debido a los factores de riesgo asociados. El sedentarismo, una alimentación inadecuada o una disminución de la sensación de saciedad son algunas de sus causas. Objetivos: evaluar las propiedades saciantes del consumo de un caldo ibérico funcional enriquecido con fosfofructooligosacáridos (FOS) en personas sanas a través de la concentración plasmática de las hormonas involucradas en el apetito. Material y métodos: ensayo clínico nutricional, agudo, cruzado, aleatorizado, doble ciego y controlado, llevado a cabo en 18 participantes aleatorizados en dos secuencias de tratamiento (caldo funcional (CF) compuesto de 5,6 g de FOS/100 g y caldo de control (CC), con 0,4 g de maltodextrina/100 g) con 14 días de lavado entre ellas. Se midieron parámetros relacionados con la saciedad (glucosa, insulina, leptina, ghrelina, GLP-1, PYY) y escalas analógicas visuales (EAV). Resultados: el porcentaje de grasa corporal disminuyó en los que tomaron el CF (-0,15 ± 0,32 vs. 0,09 ± 0,52) (p < 0,05). La concentración de leptina fue superior con el CF (p < 0,001), mostrándose dicho aumento en los tiempos -30 (p < 0,001), 0 (p < 0,001), 30 (p = 0,026) y 120 (p = 0,049) con respecto al CC. Las áreas bajo la curva (AUC) de GLP-1 (p = 0,0033) y PYY (p = 0,022) fueron superiores con el CF en comparación con el CC. Conclusión: el consumo de un caldo ibérico enriquecido con FOS mejora la concentración plasmática de las hormonas involucradas en el control de la saciedad y reduce la cantidad de grasa corporal. Dichos resultados podrían tener efectos beneficiosos para la prevención y el tratamiento del exceso de peso corporal (AU)

Introduction: excess weight represents a public health problem due to its associated risk factors. A sedentary lifestyle, an inadequate diet or a decrease in the feeling of satiety are some of the causes. Objetives: to evaluate the satiating properties of the consumption of a functional Iberian broth enriched with phospho-fructooligosaccharides (FOS) in healthy people through the plasma concentration of hormones involved in appetite. Material and methods: acute, crossover, randomized, double-blind and controlled nutritional clinical trial carried out in 18 randomized participants in two treatment sequences (functional broth (CF), composed of 5.6 g POS/100 g and control broth (CC), with 0.4 g of maltodextrin/100 g) with 14 days of washing in between. Satiety-related parameters (glucose, insulin, leptin, ghrelin, GLP-1, PYY) and visual analog scales (VAS) were measured. Results: the percentage of body fat decreased in those who took the CF (-0.15 ± 0.32 vs 0.09 ± 0.52) (p < 0.05). Leptin concentration was higher with CF (p < 0.001), which was shown at time points -30 (p < 0.001), 0 (p < 0.001), 30 (p = 0.026) and 120 (p = 0.049) when compared to CC. The areas under the curve (AUC) for GLP-1 (p = 0.0033) and PYY (p = 0.022) were higher for CF as compared to CC. Conclusion: consumption of an Iberian broth enriched with POS improves the plasma concentration of hormones involved in the control of satiety, and reduces the amount of body fat. This result could have beneficial effects for the prevention and treatment of overweight (AU)

The Role of Omega-3 Fatty Acids in Diets.

The article is a summary of Dra. Carmen Gómez Candela's presentation at the Science in Nutrition 3rd International Congress in Milan, March 2014. The article covers omega-3 fatty acids use in different medical areas and several institutions' opinions in relation to the topic. Omega-3 acids are essential fatty acids. A certain amount of omega-3 is needed in our daily diet; however, the usual consumption is generally less than the recommended amount. Changes in dietary patterns in the course of history have led to deficit levels of omega-3 in the human body. Currently, there is increasing evidence of the benefits of omega-3 in different medical specialities. There are still some gaps regarding its role in illnesses such as dementia, psychiatric disorders, and inflammatory diseases. Nevertheless, stronger evidence is being proved in cardiovascular diseases and cancer. This article provides a reflection on possible ways to increase omega-3 daily consumption and the constraints associated with food with high contents of heavy metals, which, in turn, are also rich in omega-3s.

Impact of cooked functional meat enriched with omega-3 fatty acids and rosemary extract on inflammatory and oxidative status; a randomised, double-blind, crossover study.

BACKGROUND & AIM: n-3 fatty acid intake has been associated with inflammatory benefits in cardiovascular disease (CVD). Functionalising meat may be of great interest. The aim of the present study was to assess the effect of functional meat containing n-3 and rosemary extract on inflammatory and oxidative status markers in subjects with risk for CVD. METHODS AND RESULTS: A randomised, double-blind, cross-over study was undertaken to compare the effects on the above markers of consuming functional or control meat products. 43 volunteers with at least two lipid profile variables showing risk for CVD were randomly assigned to receive functional meat (FM) or control meat (CM) over 12-weeks with a 4-week wash-out interval before crossover. Functional effects were assessed by examining lipid profile, CRP, PAI-1, TNF-alpha, IL-6, fibrinogen (inflammatory markers), and TBARS, FRAP and 8-iso-PGF2 (oxidative status markers). 33 subjects (24 women) aged 50.7±8.8 years completed the study. In FM treatment, PAI-1, fibrinogen and 8-iso-PGF2 decreased significantly after 12 weeks, while FRAP significantly increased. In contrast, in CM treatment, a significant increase was seen in PAI-1, while FRAP significantly declined. Significant differences were also seen between the FM and CM treatments after 12 weeks in terms of the change observed in PAI-1, FRAP and 8-iso-PGF2 values. No significant differences were seen in anthropometric variables nor were adverse effects reported. CONCLUSION: The consumption of FM containing n-3 and rosemary extract improved oxidative and inflammatory status of people with at least two lipid profile variables showing risk for CVD. The inclusion of such functional meat in a balanced diet might be a healthy lifestyle option.

Objetivos: La ingesta de omega-3 se ha asociado con efectos antinflamatorios relacionados con la prevención de la enfermedad cardiovascular (ECV). Desarrollar productos cárnicos funcionales podría ser de gran interés para la población. El objetivo del presente estudio fue evaluar el efecto de una carne funcional con omega-3 y extracto de romero sobre marcadores de inflamación y oxidación en personas con riesgo cardiovascular. Pacientes y métodos: Se diseñó un ensayo clínico cruzado y doble-ciego para estudiar el efecto del consumo de un producto cárnico funcional sobre marcadores de inflamación y oxidación. Se incluyeron 43 voluntarios con al menos 2 parámetros del perfil lipídico alterado, indicando riesgo de ECV. Fueron asignados aleatoriamente en 2 grupos que consumieron en cruzado carne funcional (CF) o carne control (CC) durante 12 semanas con un periodo de lavado de 4 semanas entre ellos. Al finalizar el estudio se evaluó: perfil lipídico, marcadores de inflamación (PCR, PAI-1, TNF-alpha, IL-6, fibrinógeno) y marcadores de oxidación (TBARS, FRAP, 8-iso-PGF2). Resultados: Completaron el estudio 33 personas (24 mujeres) con edad media de 50.7±8.8 años. Tras consumir CF durante 12 semanas se observó una disminución significativa del PAI-1, fibrinógeno y 8-iso-PGF2, mientras que el FRAP incrementó significativamente. Sin embargo, con CC incrementó PAI-1 y disminuyó FRAP significativamente. Además se observaron diferencias significativas entre los cambios producidos tras consumir uno u otro producto de los marcadores PAI-1, FRAP y 8-iso-PGF2. Al final de cada intervención no se observaron cambios en variables antropométricas ni efectos adversos. Conclusiones: El consumo de CF con omega-3 y extracto de romero mejora el estado inflamatorio y oxidativo de personas con al menos 2 parámetros del perfil lipídico alterado. La inclusión de estas CF en una dieta equilibrada podría ser una opción más para mantener un estilo de vida saludable. ClinicalTrials.gov NCT0199088.

Nutritional intervention in oncohematological patient.

BACKGROUND: Oncohematological diseases such as lymphoma or leukaemia affect an increasing number of newly diagnosed patients in Spain and other countries. Both disease and treatment may have a negatively impact in the nutritional status of the patient. Malnutrition is not uncommon among oncohematological patients. This situation can compromised the course of the disease, the clinical response of the treatment and the patient's quality of life. METHOD: The implementation of a multidisciplinary approach and a systematic and protocolled nutritional assessment would be useful when dealing with haematological malignancies. RESULTS: We present a proposal of protocol for nutritional intervention in oncohematological patients. This proposal is been developed from the analysis of the published literature as well as clinical practice of a multi-disciplinary team specialized in the management of patients with haematological malignancies.

Intervención nutricional en el paciente oncohematológico / Nutritional intervention in oncohematological patient

Objetivos: Las enfermedades oncohematológicas como el Linfoma o la Leucemia afectan a un número importante y creciente de personas en España. Tanto la enfermedad como las distintas modalidades de tratamiento que puede llegar a precisar el paciente a lo largo del curso de la misma impactan negativamente en el estado nutricional del paciente, no siendo infrecuente el desarrollo de desnutrición, situación que compromete la evolución, la respuesta al tratamiento y la calidad de vida del paciente. Método: La implementación de una estrategia multidisciplinar, sistematizada y protocolizada de valoración nutricional puede resultar de utilidad a la hora de abordar a los pacientes con enfermedades oncohematológicas. Resultados: Se presenta una propuesta de protocolo de evaluación y soporte nutricional en el paciente oncohematológico elaborada a partir del análisis de la literatura publicada al respecto, así como de la práctica clínica habitual de un equipo sanitario multidisciplinar especialmente implicado en el manejo de los pacientes con enfermedades oncohematológicas (AU)

Parámetros hormonales e inflamatorios en un grupo de mujeres con sobrepeso/obesidad / Hormonal an inflammatory biomarkers in a group of overweight and obese women

Introducción y Objetivos: Recientemente se ha descubierto que la obesidad es una patología caracterizada por un estado crónico de inflamación leve. El objetivo de este estudio fue describir la situación hormonal e inflamatoria de un colectivo de mujeres con sobrepeso/obesidad. Pacientes y métodos: se incluyeron mujeres > 18 años, con IMC ≥ 25 < 40 kg/m2. Se recogieron datos ocio-sanitarios, presión arterial, parámetros antropométricos, de actividad física, estudio bioquímico, hormonal e inflamatorio para determinar la situación hormonal e inflamatoria de un colectivo de mujeres antes del inicio de un tratamiento para el control de peso corporal. Resultados: participaron 104 mujeres con edad media de 48,4 ± 9 años y un IMC de 29,8 ± 3,5 kg/m2. Un 48% de las mujeres estudiadas se encontraba en etapa de menopausia. Un 8,9% presentó hiperinsulinemia. El valor medio obtenido de grhelina fue 38,8 ± 33,6 pg/ml, no se encontró correlación entre sus concentraciones y las variables antropométricas y bioquímicas estudiadas. Los valores medios de PCR, leptina, adiponectina, resistina, IL 6, IL 10 y PAI 1 fueron 3,0 ± 2,7 mg/dl, 36,3 ± 19,5 ng/ml, 8,3 ± 4,5 μg/ml, 24,3 ± 23,2 ng/ml, 51,6 ± 93,6 pg/ml, 10,0 ± 34,2 pg/ml y 22,3 ± 30,6 ng/ml, respectivamente. Estas concentraciones correlacionaron significativamente con diferentes variables antropométricas y bioquímicas, sin embargo, estas correlaciones fueron débiles. Variables como la edad y presencia o no de menopausia o la práctica de actividad física de forma regular no influyeron en los valores medios obtenidos. Las pacientes con obesidad tuvieron valores medios significativamente más elevados que aquellas con sobrepeso, aunque sólo en el caso de la resistina y PAI 1. Conclusión: El grupo de mujeres estudiadas presentó cifras de adipoquinas alteradas en relación a otros estudios realizados en población con situación nutricional normal. Esto pone en evidencia la situación inflamatoria presente en estos pacientes y los valores obtenidos pueden contribuir a establecer unos rangos normalizados de estos marcadores para el colectivo de personas con sobrepeso y obesidad (AU)

Background and objectives: The aim of this study was to describe the hormonal and inflammatory status of a group of overweight/obese women. Patients and methods: The sample studied was a crosssectional cohort of women > 18 years of age, BMI ≥ 25 <40 kg/m2, prior to starting a weight control program. Data collected were: demographic characteristics, blood pressure, anthropometric parameters, physical activity data, and biochemical, hormonal and inflammatory biomarkers. Results: The study involved 104 women with a meanage of 48.4 ± 9 years and a BMI of 29.8 ± 3.5 kg/m2. Some 48% of the women studied were in menopause. Some8.9% had hyper insulinemia. The mean ghrelin value was38.8 ± 33.6 pg/ml; there was no correlation between ghrelinlevels and anthropometric and biochemical variables.CRP, leptin, adiponectin, resistin, IL6, IL10, and PAI1were 3.0 ± 2.7 mg/dl, 36.3 ± 19.5 ng/ml, 8.3 ± 4.5 mg/ml,24.3 ± 23.2 ng/ml, 51.6 ± 93.6 pg/ml, 10.0 ± 34.2 pg/ml and22.3 ± 30.6 ng/ml, respectively. Obese patients had significantly higher mean values of resistin and PAI 1 than those who were overweight. These levels correlated significantly with anthropometric and biochemical variables; however, the correlations were weak. Age, menopause or the regular practice of physical activity had no effect on mean values. Conclusions: The group of women studied had altered inflammatory biomarkers in relation to people of normal weight. The study shows the inflammatory status of overweight/obese individuals, and the values obtained may help to establish standard ranges for these markers (AU)

Factores que condicionan la aceptación y consumo de los suplementos nutricionales en el paciente ingresado / Factors determining the compliance and intake of nutritional supplements in hospitalized patients

La malnutrición calórico-proteica, que puede afectar al 30-50% de los pacientes hospitalizados, aumenta el tiempo de hospitalización y el coste por proceso patológico en nuestros pacientes. Existe suficiente evidencia científica que avala que la administración de suplementos nutricionales (SN) puede mejorar tanto parámetros nutricionales como funcionales y previene la aparición de malnutrición en pacientes que no cubren todas sus necesidades nutricionales con la dieta convencional o con la dieta adaptada. También, se ha documentado que pueden reducir la duración de la estancia hospitalaria y las tasa de mortalidad en algunas condiciones. Sin embargo, se ha observado, tanto en la práctica clínica habitual como en algunos ensayos clínicos, que el cumplimiento terapéutico y la adherencia al tratamiento son bajos, observándose en algunos ensayos que hasta menos de la mitad de los pacientes llegaban a consumir lo prescrito. Son múltiples los factores que intervienen en el cumplimiento terapéutico, aunque hasta el momento, no han sido bien estudiados. En este artículo, vamos a hacer una reflexión sobre este aspecto. Las causas que ocasionan este incumplimiento se podrían agrupar en tres tipos de motivos: factores socio sanitarios, factores relacionados con el paciente y su patología; y factores relacionados con las características de los suplementos. Entre los factores socio sanitarios, cabe destacar aquellos relacionados con la adecuada formación en Nutrición de los médicos y de todos los profesionales sanitarios implicados en el tratamiento del paciente, así como la implicación en el tratamiento por parte de los cuidadores en general, incluyendo a los familiares; siendo fundamental el tipo de institución en la que se encuentra ingresado el paciente (sobre todo cuando se trata de unidades de agudos frente a las de crónicos ) y de la existencia de servicio de nutrición en el centro en cuestión. Entre los factores dependientes del paciente son importantes: la edad, pues se describe peor adherencia en los más mayores; la patología de base: la presencia de enfermedad tumoral, la insuficiencia renal, la disgeusia y disfagia, entre otras causas, condicionan una peor adherencia al tratamiento), así como la duración del ingreso, ya que cuando se prolonga empeora también la adherencia. Finalmente, también tienen trascendencia los factores relacionados con el suplemento en sí mismo, en función de su composición, forma de presentación, tipo de envase y sus características organolépticas (olor, sabor y textura). Hecha esta reflexión se sugieren unas pautas a seguir para conseguir una tasa mayor de cumplimiento del tratamiento indicado con suplementos nutricionales al paciente ingresado (AU)

Protein-calorie malnutrition, which can affect 30-50% of hospitalized patients, increases the length of hospital stay and cost per pathological process in our patients. There is enough scientific evidence supporting that the administration of nutritional supplements (NS) can improve both nutritional and functional parameters and prevents malnutrition in patients who do not meet all their nutritional needs through conventional diet or with an adapted diet. It has also been documented that NS can reduce the length of hospital stay and mortality rate in some conditions. However, it has been observed both in clinical practice and in some clinical trials that compliance and adherence are low. In fact, in some trials, less than half of the patients came to consume the supplements prescribed. There are many factors involved in adherence, but so far they have not been properly analyzed. In this article, we want to reflect on this matter. The reasons behind this lack of compliance could be grouped into three categories: socio-sanitary factors, factors related to the patient and its pathology, and those related to the characteristics of supplements. Among the socio-sanitary factors, it should be highlighted the relevance of adequate nutrition training of physicians and all health professionals involved in patient care, the collaboration in the treatment by caregivers, including family, being essential to this matter the type of institution where the patient is admitted (especially when it comes to acute care units compared to those of chronic care) and the availability of a nutrition service at the center in question. Regarding patient-dependent factors, the most important are: age, as it has been described poorer adherence in the elderly, the underlying disease (the presence of oncologic disease, kidney failure, dysgeusia and dysphagia, among other causes, determine a worse adhesion to treatment) and length of stay, with longer stays correlating with a lesser grade of compliance. Finally, there are also of relevance the factors related to the supplement itself, such as their composition, presentation, packing and their organoleptic properties (smell, taste and texture). Once made this reflection, we suggest some advices to achieve a higher rate of compliance with the prescribed nutritional supplements in hospitalized patients (AU)

Obese patients had significantly higher mean values of resistin and PAI 1 than those who were overweight. These levels correlated significantly with anthropometric and biochemical variables; however, the correlations were weak. Age, menopause or the regular practice of physical activity had no effect on mean values. CONCLUSIONS: The group of women studied had altered inflammatory biomarkers in relation to people of normal weight. The study shows the inflammatory status of overweight/ obese individuals, and the values obtained may help to establish standard ranges for these markers.

Self-limited acute hepatotoxicity caused by pegvisomant.

We present a case of acute severe hepatitis in a patient with acromegaly receiving combination therapy with somatostatin analogs and pegvisomant. Hepatitis resolved completely 18 weeks after diagnosis of hypertransaminasemia without discontinuation of therapy and with a close clinical and biochemical follow-up. In this case, despite the severity of the hepatitis, therapy could be continued as hypertransaminasemia was gradually decreasing after the maximum peak. We also review the literature on toxic hepatitis associated to pegvisomant therapy analyzing the etiology, clinical predisposing factors and natural evolution.
