Papel de la farmacia comunitaria en la Unión Europea durante la pandemia provocada por el virus SARS-COV-2 / Role of community pharmacy in the European Union during the SARS-COV-2 pandemic

JUSTIFICACIÓN: la actual pandemia de COVID-19 ha provocado que, a las tradicionales funciones asistenciales, se hayan incorporado nuevos y diferentes servicios profesionales por parte de los farmacéuticos comunitarios en la Unión Europea.OBJETIVOS: comparar las competencias desarrolladas por los farmacéuticos comunitarios españoles y resto de europeos durante la pandemia provocada por el virus SARS-CoV-2.MATERIAL Y MÉTODOS: revisión bibliográfica en Pubmed y Google académico usando la siguiente estrategia de búsqueda: ("Pharmacy"[Mesh] OR "Community Pharmacy Services"[Mesh]) AND ("COVID-19"[Mesh] OR "SARS-CoV-2"[Mesh] OR "COVID-19 Testing"[Mesh]). La información obtenida se completó con documentos elaborados por la Organización Mundial de la Salud, el Ministerio de Sanidad y el Consejo General de Colegios Oficiales de Farmacéuticos de España.RESULTADOS/DISCUSIÓN: en países como Portugal se pudieron dispensar medicamentos de uso hospitalario en farmacias comunitarias. En España esto ha ocurrido, pero de forma minoritaria. En Alemania, pueden cambiar el tamaño del envase o de la concentración del medicamento en caso de desabastecimiento. En España solo en algunas Comunidades Autónomas (CCAA) y de manera excepcional. En Reino Unido, se potencia, incluso con publicidad televisiva, el que los pacientes acudan a la farmacia comunitaria si padecen un síntoma menor, lo que no ha sido posible en ninguna Comunidad española.

Orejas en asa. Presentación de casos y revisión bibliográfica / Earpining. Presentation of cases and bibliographic review

Las orejas prominentes se deben a una o varias anomalías congénitas que pueden asociarse entre sí en grados diversos. Los pabellones auriculares son considerados demasiado visibles tanto por la falta de plegamiento del antihélix, la abertura del ángulo cefaloconchal y la hipertrofia de la concha, según la clasificación de Davis. Son un problema estético frecuente, observándose en el 5% de la población. El conocimiento de la anatomía del pabellón normal y de los criterios antropométricos es indispensable. El grosor del cartílago condiciona la rigidez y la elasticidad del pabellón, mientras que sus relieves definen la forma y la posición. La finalidad en la otoplastia es corregir estas anomalías, remodelando el cartílago para obtener unas orejas con una plicatura adecuada, situadas y orientadas según parámetros estéticos, simétricas, con un tamaño y aspecto natural. Se pueden combinar distintos procedimientos quirúrgicos los cuales deben ser simples, rápidos, tener un resultado armonioso y duradero. Se realizó una revisión retrospectiva entre los años 2018 a 2020 en el Servicio de Cirugía Plástica del Hospital Tornú, en la que se presentan 4 casos de orejas prominentes a los cuales se les realizaron diferentes técnicas quirúrgicas de otoplastia (Davis, Stentstrom y Furnas). El total de los pacientes (n=4) tratados presentó un resultado satisfactorio tanto para el paciente como para el equipo quirúrgico, sin complicaciones significativas. La resolución quirúrgica de las orejas prominentes puede realizarse mediante numerosas técnicas; estas se dividen entre aquellas que realizan un procedimiento agresivo sobre el cartílago (resectivas) y las que intentan ser más conservadoras, sin resección del mismo para evitar al máximo las complicaciones. La diversidad de enfoques indica que no existe una técnica definitiva para corregir estos problemas. Las orejas prominentes o en asa, si bien no presentan alteraciones funcionales, tienen consecuencias sobre los efectos estéticos y psicológicos en el paciente que pueden ser sustanciales. Es importante conocer su base anatómica y realizar una adecuada evaluación, elegir técnicas para la corrección de la deformidad y conocer las posibles complicaciones del procedimiento para obtener un buen resultado estético y duradero.

Prominent ears are due to one or more congenital anomalies that may be associated with each other to varying degrees. The pinnae are considered too visible due to the lack of folding of the antihelix, the opening of the cephalo-conchal angle and the hypertrophy of the concha, according to the Davis classification. They are a frequent esthetic problem, being observed in 5% of the population. Knowledge of normal pinna anatomy and anthropometric criteria is essential. The thickness of the cartilage determines the rigidity and elasticity of the pinna, while its relief defines its shape and position. The purpose of otoplasty is to correct these anomalies, remodeling the cartilage to obtain ears with an adequate plication, positioned and oriented according to aesthetic parameters, symmetrical, with a natural size and appearance. Different surgical procedures can be combined, which must be simple, fast, have a harmonious and lasting result. A retrospective review was performed from 2018 to 2020 in the Plastic Surgery Department of the Tornú Hospital, presenting 4 cases of prominent ears which underwent different otoplasty surgical techniques (Davis, Stentstrom and Furnas). The total number of patients (n=4) treated presented a satisfactory result for both the patient and the surgical team without significant complications. Surgical resolution of protruding ears can be performed by numerous techniques, divided between those that perform an aggressive procedure on the cartilage (resective) and those that try to be more conservative, without resection of the cartilage to avoid complications as much as possible. The diversity of approaches indicates that there is no definitive technique to correct these problems. Prominent or protruding ears, although they do not present functional alterations, the consequences on the esthetic and psychological effects on the patient can be substantial. It is important to know their anatomical basis and to perform an adequate evaluation, to choose techniques for the correction of the deformity and to know the possible complications of the procedure in order to obtain a good esthetic and lasting result.

Resolución de hipertrofia de labios menores mediante técnicas simples / Resolution of hypertrophy of the labia minora using simple techniques

Introducción. La hipertrofia de los labios menores se define como tejido labial que sobresale más allá de los labios mayores, puede afectar de manera uni- o bilateral y resultar en dispareunia, interferencia con los deportes, dificultades con la limpieza, irritación e infecciones crónicas del tracto urinario, incomodidad para el uso de prendas ajustadas, además de trastornos psicológicos. Todos estos motivos llevan a las mujeres a la consulta. La reducción de labios menores es el procedimiento estético genital femenino más común. Este trabajo tiene como objetivo presentar técnicas de baja complejidad para resolver diferentes grados de hipertrofia de labios menores. Materiales y métodos. Estudio retrospectivo, observacional que comprendió 3 pacientes entre el periodo de marzo del 2019 a febrero 2020 que Incluyó a pacientes con hipertrofias leves y moderadas. Resultados. En 2 pacientes se realizó escisión directa y en 1, técnica del desepitelizado más lipotransferencia de labios mayores, sin evidenciar complicaciones mayores. Discusión. Si bien en la literatura se han reportado un gran número de técnicas quirúrgicas, cada una de ellas debe adecuarse al tipo de hipertrofia labial. La técnica del desepitelizado permite conservar un borde natural, con conservación de la coloración y textura original de la paciente, aporte neurovascular, pero no es conveniente utilizarla en pacientes de grados mayores de hipertrofia. La escisión directa proporciona una técnica simple para la escisión del exceso de tejido en pacientes con mayor tamaño de sus labios menores, pero elimina el contorno, la coloración y la textura naturales del borde libre, aun así, las pacientes resultan conformes con su nuevo aspecto. Conclusión. La reconstrucción de los labios menores, utilizando las técnicas de desepitelización y escisión directa, es confiable y da un resultado cosmético y funcional exitoso. Estas técnicas son de baja complejidad, tiempo operatorio breve, técnicamente reproducibles, dando gran conformidad y resultando un método seguro

Introduction. Hypertrophy of the labia minora is defined as lip tissue that protrudes beyond the labia majora, can affect unilaterally or bilaterally and result in dyspareunia, interference with sports, difficulties with cleaning, irritation and chronic infections of the urinal tract, discomfort for wearing tight clothes, in addition to psychological disorders. All these reasons lead women to the consultation. Labia minora reduction is the most common female genital cosmetic procedure. This work aims to present low complexity techniques to resolve different degrees of hypertrophy of the labia minora. Materials and methods: retrospective, observational study that comprised 3 patients between the period of March 2019 to February 2020 that included patients with mild and moderate hypertrophy. Results: Direct excision was performed in 2 patients and in 1, de-epithelialization technique plus lipotransference of the labia majora. Without showing major complications. Discussion: Although a large number of surgical techniques have been reported in the literature, each of them must be adapted to the type of lip hypertrophy. The de-epithelialization technique allows a natural border to be preserved, with preservation of the patient's original color and texture, neurovascular supply, but it is not convenient to use it in patients with higher degrees of hypertrophy. Direct excision provides a simple technique for excision of excess tissue in patients with larger labia minora, but removes the natural contour, coloration and texture of the free edge, yet patients are still satisfied with their new appearance. Conclusion. The reconstruction of the labia minora, using de-epithelialization and direct excision techniques is reliable and gives a successful cosmetic and functional result. These are low complexity techniques, short operating time, technically reproducible, giving great conformity and resulting in a safe method

Factors associated with sepsis development in 606 Spanish adult patients with cellulitis.

BACKGROUND: Cellulitis, a frequent cause of admission of adult patients to medical wards, occasionally evolves to sepsis. In this study we analyze the factors related to sepsis development. METHODS: Prospective and observational study of 606 adult patients with cellulitis admitted to several Spanish hospitals. Comorbidities, microbiological, clinical, lab, diagnostic, and treatment data were analyzed. Sepsis was diagnosed according to the criteria of the 2016 International Sepsis Definitions Conference. Multiple logistic regression modelling was performed to determine the variables independently associated with sepsis development. RESULTS: Mean age was 63.4 years and 51.8% were men. Overall 65 (10.7%) patients developed sepsis, 7 (10.8%) of whom died, but only 4 (6.2%) due to cellulitis. Drawing of blood (P < 0.0001) or any (P < 0.0001) culture, and identification of the agent (P = 0.005) were more likely among patients with sepsis. These patients had also a longer duration of symptoms (P = 0.04), higher temperature (P = 0.03), more extensive cellulitis (P = 0.02), higher leukocyte (P < 0.0001) and neutrophil (P < 0.0001) counts, serum creatinine (P = 0.001), and CRP (P = 0.008) than patients without sepsis. Regarding therapy, patients with sepsis were more likely to undergo changes in the initial antimicrobial regimen (P < 0.0001), received more antimicrobials (P < 0.0001), received longer intravenous treatment (P = 0.03), and underwent surgery more commonly (P = 0.01) than patients without sepsis. Leukocyte counts (P = 0.002), serum creatinine (P = 0.003), drawing of blood cultures (P = 0.004), change of the initial antimicrobial regimen (P = 0.007) and length of cellulitis (P = 0.009) were independently associated with sepsis development in the multivariate analysis. CONCLUSIONS: Increased blood leukocytes and serum creatinine, blood culture drawn, modification of the initial antimicrobial regimen, and maximum length of cellulitis were associated with sepsis in these patients.

Very low level viraemia and risk of virological failure in treated HIV-1-infected patients.

OBJECTIVES: The aim of the study was to investigate whether very low level viraemia (VLLV) (20-50 HIV-1 RNA copies/mL) was associated with increased risk of virological failure (VF) as compared with persistent full suppression (< 20 copies/mL). METHODS: From the VACH Cohort database, we selected those patients who started antiretroviral therapy (ART) after January 1997 and who achieved effective viral suppression [two consecutive viral loads (VLs) < 50 copies/mL] followed by full suppression (at least one VL <20 copies/mL). We carried out survival analyses to investigate whether the occurrence of VLLV rather than maintaining full suppression at < 20 copies/mL was associated with virological failure (two consecutive VLs > 200 copies/mL or one VL > 200 copies/mL followed by a change of ART regimen, administrative censoring or loss to follow-up), adjusted for nadir CD4 cell count, sex, age, ethnicity, transmission group, type of ART and time on effective suppression at < 50 copies/mL. RESULTS: Of 21 480 patients who started ART, 13 674 (63.7%) achieved effective suppression at < 50 copies/mL, of whom 4289 (31.4%) further achieved full suppression at < 20 copies/mL after May 2009. A total of 2623 patients (61.1%) remained fully suppressed thereafter, while 1666 had one or more episodes of VL detection > 20 copies/mL (excluding virological failure). A total of 824 patients had VLLV after suppression at < 20 copies/mL. VLLV was not associated with virological failure as compared with persistent full suppression [hazard ratio (HR) 0.67; 95% confidence interval (CI) 0.44-1.00], independently of the number of blips recorded (from one to 18). CONCLUSIONS: In our population of HIV-infected patients on ART who achieved viral suppression at < 20 copies/mL, the risk of virological failure was no different for patients who remained fully suppressed compared with those who experienced subsequent episodes of VLLV.

Polymorphism of neuropeptide Y gene rs16147 modifies the response to a hypocaloric diet on cardiovascular risk biomarkers and adipokines.

BACKGROUND: The main genetic variant described in NPY gene is rs16147 (G-399A) and it is located within the promoter region upstream of the gene for neropeptide Y (NPY). We evaluate the effects of the rs16147 NPY gene polymorphism on metabolic changes secondary to weight loss after 3 months of a hypocaloric diet in adult obese patients. METHODS: A population of 82 obese patients was analysed in an interventional design of one arm. Before and after 3 months on a hypocaloric diet, an anthropometric evaluation, an assessment of nutritional intake and a biochemical analysis were performed. The statistical analysis was performed for combined GA and AA as a group (minor allele group) and GG as second group (major allele group) (dominant model). RESULTS: In A allele carriers, the mean (SD) decrease in weight was -2.8 (2.2) kg [decrease in non A allele carriers -2.6 (1.1) kg, P > 0.05), body mass index was -1.2 (0.6) kg m-2 [decrease in non A allele carriers -1.1 (0.8) kg m-2 , P > 0.05], fat mass was -1.7 (1.4) kg [decrease in non A allele carriers -1.9 (1.3) kg, P > 0.05], waist circumference was -5.5 (3.4) cm [decrease in non A allele carriers -3.7 (4.1) cm, P = 0.006], C-reactive protein (CRP) was -0.7 (0.6) mg dL-1 [decrease in non A allele carriers -0.1 (0.3) mg dL-1 , P = 0.02], insulin was -1.5 (0.4) mUI L-1 [decrease in non A allele carriers -0.8 (2.0) mUI L-1 , P = 0.001] and homeostasis model assessment-insulin resistance (HOMA-IR) was -0.4 (0.5) [decrease in non A allele carriers -0.2 (0.1), P = 0.005]. interleukin (IL)-6 changes were significant in A allele carriers [-0.7 (0.2) pg mL-1 ] versus non A allele carriers [-0.1 (0.3) pg mL-1 ] (P = 0.01). CONCLUSIONS: We found that the rs164147 genotype affected the reduction of waist circumference, HOMA-IR, insulin, CRP and IL-6 levels in response to weight loss diet in obese subjects.

Factors associated with long-term CD4 cell recovery in HIV-infected patients on successful antiretroviral therapy.

OBJECTIVES: The aim of the study was to study the factors associated with immunological recovery in HIV-infected patients with suppressed viral load. METHODS: Nadir and current CD4 cell counts were recorded in 821 patients, as well as many demographic, epidemiological, lifestyle, clinical, therapeutic, genetic, laboratory, liver fibrosis and viral hepatitis parameters. RESULTS: The median age of the patients was 44.4 years [interquartile range (IQR) 40.3-48.0 years], the median time since HIV diagnosis was 15.3 years (IQR 10.5-18.9 years), the median time of suppressed viral load was 7.0 years (IQR 4.0-10.0 years) and the median time on the current antiretroviral regimen was 2.8 years (IQR 1.4-4.7 years). The median nadir and current CD4 counts were 193.0 (IQR 84.0-301.0) and 522.0 (IQR 361.0-760) cells/µL, respectively, separated by a median period of 10.2 years (IQR 5.9-12.9 years). The median CD4 count gain during follow-up was 317.0 (IQR 173.0-508.0) cells/µL. Many variables were associated with CD4 cell gains in univariate analyses, including age, gender, epidemiology, prior clinical conditions, fibrosis stage, transient elastometry, aspartate aminotransferase (AST), nadir CD4 count and hepatitis B and C virus infections and genotypes, as well as the durations of follow-up since nadir CD4 count, overall antiretroviral treatment, current antiretroviral regimen, protease inhibitor therapy and suppression of viral load. Multivariate analysis revealed that longer duration of HIV suppression (P < 0.0001), more advanced clinical Centers for Disease Control and Prevention (CDC) stages (P < 0.0001), younger age (P = 0.0003), hepatitis C virus genotypes 1 and 4 (P = 0.003), sexual acquisition of HIV (P = 0.004), and lower transient elastometry values (P = 0.03) were independent predictors of CD4 cell gains. Overall, the model accounted for 14.2% of the variability in CD4 count. CONCLUSIONS: In addition to the duration of HIV suppression, HIV-related diseases, HIV epidemiology, age, hepatitis C virus genotypes, and liver fibrosis were independently associated with long-term immunological recovery.

Fístula colecistocutánea espontánea / Spontaneous cholecystocutaneous fistula

Background: Spontaneous cholecystocutaneous fistula is a rare complication of acute cholecystitis. The incidence has decreased due to prompt and early surgical management of patients with acute cholecystitis. Case report: We report a 64 years old woman consulting for erythematous soft and non-tender mass in right flank. Ultrasound revealed the cholecystocutaneous fistula. The fistulous tract and the gallbladder were excised from average laparotomy.

Introducción: La fístula colecistocutánea es una rara complicación de la colecistitis aguda. La incidencia de esta patología ha disminuido debido al abordaje quirúrgico precoz de los pacientes con colecistitis aguda. Caso clínico: Reportamos el caso de una mujer de 64 años de edad que consulta por un nódulo con signos inflamatorios en el flanco derecho. La fístula fue diagnosticada mediante ecografía. La fístula y la vesícula fueron extirpadas mediante una laparotomía media.

Effect of Lys656Asn Polymorphism of Leptin Receptor Gene on Cardiovascular Risk Factors and Serum Adipokine Levels after a High Polyunsaturated Fat Diet in Obese Patients.

BACKGROUND: Human obesity is characterized by high levels of leptin, and leptin levels may change with weight loss and dietary restriction. The aim of our study was to investigate the influence of Lys656Asn polymorphism in the leptin receptor gene on cardiovascular risk factors, weight loss, and serum leptin levels to a high polyunsaturated fatty acid (PUFA) hypocaloric diet in obese patients. DESIGN: A sample of 132 obese patients was analyzed in a prospective way with a dietary intervention. The enriched PUFAs hypocaloric intervention consisted in a diet of 1,459 kcal, 45.7% of carbohydrates, 34.4% of lipids, and 19.9% of proteins. RESULTS: In wild-type group, BMI (-1.9 ± 1.4 kg/m(2) ), weight (-4.4 ± 3.2 kg), fat mass (-4.2 ± 3.8 kg), waist circumference (-4.1 ± 3.1 cm), systolic blood pressure (-7.0 ± 12.1 mmHg), diastolic blood pressure (-3.9 ± 6.8 mmHg), insulin (-1.8 ± 5.6 MUI/l) and HOMA-IR (-0.5 ± 1.5 Units) decreased. In mutant genotype group, BMI (-2.0 ± 2.1 kg/m(2) ), weight (-3.6 ± 4.1 kg), waist circumference (-3.1 ± 4.1 cm), total cholesterol (-25.2 ± 19.6 mg/dl), LDL cholesterol (-16.6 ± 25.6 mg/dl), and tryglicerides (-26.6 ± 39.1 mg/dl) decreased. Only leptin levels have a significant decrease in wild genotype group (-6.6 ± 10.2 ng/ml) (25.1%). CONCLUSION: Carriers of ASn656 allele have a different response than wild-type obese, with a lack of decrease in insulin levels, leptin levels, and HOMA-IR. However, obese patients with this mutant allele have a better lipid profile after weight loss.

Relation of the rs6923761 gene variant in glucagon-like peptide 1 receptor with weight, cardiovascular risk factor, and serum adipokine levels in obese female subjects.

BACKGROUND: Studies of the glucagon-like peptide 1 (GLP-1) receptor have been directed at identifying polymorphisms in the GLP-1 receptor gene that may be a contributing factor in the pathogenesis of diabetes mellitus and cardiovascular risk factors. Nevertheless, the role of GLP-1 variants on body weight, cardiovascular risk factors, and adipokines remains unclear in obese patients. OBJECTIVE: Our aim was to analyze the effects of rs6923761 GLP-1 receptor polymorphism on body weight, cardiovascular risk factors, and serum adipokine levels in nondiabetic obese females. DESIGN: A sample of 645 obese nondiabetic Caucasian females was enrolled in a prospective way. Basal fasting glucose, c-reactive protein (CRP), insulin, insulin resistance (homeostasis model assessment (HOMA)), total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides concentration, and adipokines were measured. Weights, body mass index (BMI), waist circumference, fat mass by bioimpedance, and blood pressure measures were measured. RESULTS: Three hundred and twenty-seven participants (50.7%) had the genotype GG and 318 (49.3%) study subjects had the next genotypes; GA (270 study subjects, 41.9%) or AA (48 study subjects, 7.4%) (second group). In wild group (GG genotype), BMI (1.8 ± 2.3 kg/m(2) ; P < 0.05), weight (3.1 ± 1.3 kg; P < 0.05), fat mass (2.4 ± 1.1 kg; P < 0.05), waist circumference (2.7 ± 1.9 cm; P < 0.05), triglyceride levels (10.4 ± 5.3 mg/dl; P < 0.05), interleukin 6 (IL-6) (1.5 ± 0.9 ng/dl; P < 0.05), resistin (1.1 ± 0.3 ng/dl; P < 0.05), and leptin (30.1 ± 10.3 ng/dl; P < 0.05) levels were higher than mutant group (GA + AA). CONCLUSION: Data from our study revealed an association with decreased metabolic and cardiovascular markers in obese females. BMI weight, fat mass, waist circumference, triglycerides, leptin, resistin, and IL-6 serum levels were lower in subjects with A allele than non-A allele subjects.

Effect of a high monounsaturated vs high polyunsaturated fat hypocaloric diets in nonalcoholic fatty liver disease.

OBJECTIVE: Hyperaminotransferasemia is an important problem in obese patients. We decide to examine the changes in hyperaminotransferasemia after weight reduction in obese patients with and without NAFLD secondary to a high monounsaturated fat vs. a high polyunsaturated fat hypocaloric diets. PATIENTS AND METHODS: A population of 306 obese patients was randomly allocated to two groups: Diet M (high monounsaturated fat hypocaloric diet) and Diet P (high polyunsaturated fat hypocaloric diet). Patients were classified as group I (obese subjects; n=262) when serum ALT activity was normal or group II (NAFLD patients; n=44) when serum ALT activity was (≥ 43 UI/L). RESULTS: In NAFLD group with diet M, BMI, weight, fat mass, waist circumference, systolic blood pressure, total cholesterol, LDL cholesterol), insulin and HOMA-R decreased. In NAFLD group with diet P, BMI, weight, fat mass, waist circumference, systolic blood pressure, total cholesterol, LDL cholesterol), insulin and HOMA-R decreased, too. In NAFLD group, alanine aminotransferase [(diet M) -20.3±19.2 UI/L vs. (diet P) -14.2±20.1 UI/L], aspartate aminotransferase [(diet M) -11.3±12.2 UI/L vs. (diet P) -11.1±10.1 UI/L], and gammaglutamyl transferase [(diet M) -18.1±12.2 UI/L vs. (diet P) -10.9±20.1 UI/L] improved with both diets. CONCLUSIONS: We showed that weight reduction secondary to two hypocaloric diets was associated with improvement in hypertransaminasemia and insulin resistance in NAFLD patients.

Clinical effects of a hypercaloric and hyperproteic oral suplemment enhanced with W3 fatty acids and dietary fiber in postsurgical ambulatory head and neck cancer patients.

BACKGROUND: Patients with head and neck cancer undergoing surgery have a high risk of nutritional complications. OBJECTIVE: The aim of our study was to investigate the influence of a hypercaloric and hyperproteic oral supplement enriched with w3 FATTY ACIDS and fiber in clinical parameters in head and neck tumor postsurgical ambulatory patients with or without radiotherapy. DESIGN: A population of 37 ambulatory postsurgical patients with oral and laryngeal cancer was enrolled. At Hospital discharge postsurgical head and neck cancer patients were asked to consume two units per day of a hypercaloric and hyperproteic oral supplement for a twelve week period. RESULTS: The mean age was 63.8+/-7.1 years (16 female/ 21 males). Duration of supplementation was 98.1±19.1 days. A significant increase of albumin and transferrin levels was observed, in total group and in patients undergoing radiotherapy and without it. No differences were detected in weight and other anthropometric parameters in total group and in patients with radiotherapy during the protocol. Nevertheless, patients without radiotherapy showed a significant improvement of BMI; weight, fat free mass and fat mass. CONCLUSIONS: An omega 3 and fiber enriched formula improved seric protein levels in ambulatory postoperative head and neck cancer patients. Improvement of weight, fat mass and fat free mass was observed in patients whom not received radiotherapy during the follow up.

Antecedentes: Los pacientes con tumores de cabeza y cuello sometidos a cirugía presentan un alto riesgo de complicaciones nutricionales. Objetivo: El principal objetivo de nuestro trabajo fue evaluar la influencia de un suplemento hiperenergético e hiperproteico enriquecido en ácidos grasos w3 y fibra en pacientes postquirúrgicos ambulatorios con tumores de cabeza y cuello, con y sin radioterapia. Diseño: Una muestra de 37 pacientes postquirúrgicos ambulatorios con tumores de cabeza y cuello fue evaluada. Tras el alta hospitalaria, los pacientes recibieron dos envases al día de un suplemento hiperproteico e hipercalórico durante 12 semanas. Resultados: La edad media fue de 63.8+/-7.1 años (16 mujeres/21 varones). La duración media de la suplementación fue de 98.1±19.1 días. Se detectó un aumento significativo en los niveles de albúmina y transferrina en los pacientes del grupo global, en los que recibieron radioterapia y en los que no al recibieron. El peso y los parámetros antropométricos no mejoraron en el grupo global ni en los que recibieron radioterapia. Sin embargo los pacientes que no recibieron radioterapia tuvieron un aumento de la masa magra, peso y masa grasa Conclusiones: La formula enriquecida en omega 3 y fibra mejoró lo niveles de proteínas séricas. Por otra parte los pacientes que no recibieron radioterapia durante el seguimiento presentaron un aumento del peso, masa grasa y masa magra.

Relation of -55CT polymorphism of UCP3 gene with weight loss and metabolic changes after a high monounsaturated fat diet in obese non diabetic patients.

AIMS: The aim of our study was to investigate the influence of -55CT polymorphism of UCP3 gene on metabolic response, weight loss and serum adipokine levels to a high monounsaturated fat hypocaloric diet in obese patients. PATIENTS AND METHODS: A sample of 128 obese patients was analyzed in a prospective way during 3 months. RESULTS: Eighty eight patients (21 males/67 females) (68.8%) had the genotype 55CC (wild genotype group) and 40 patients (8 males/32 females) (31.3%) 55CT (mutant genotype group). In wild genotype group, BMI (-1.6±1.3 kg/m2), weight (-4.3±3.7 kg), fat mass (-3.5±3.3 kg), waist circumference (-5.1±2.9 cm), total cholesterol (-7.2±10.6 mg/dl), LDL cholesterol (-5.3±12.8 mg/dl) and leptin (-4.7±10.1 ng/ml) decreased. In mutant genotype group, BMI (1.3±2.2 kg/m2), weight (-3.0±1.4 kg), fat mass (-2.5±1.1 kg), waist circumference (-2.8±3.1 cm) and leptin (-5.8±10.7 decreased. CONCLUSIONS: In patients with -55CC UCP3 genotype, a high mono-unsaturated hypocaloric diet reduced BMI, weight, waist circumference, waist to hip ratio, fat mass, LDL-cholesterol, total cholesterol and leptin levels. Carriers of T allele had a different response than -55CC patients, with a significant decrease of the same antropometric parameters, but lower than in the wild genotype group, and without significant changes in cholesterol levels.

Role of insulin resistance and adipocytokines on serum alanine aminotransferase in obese patients with type 2 diabetes mellitus.

BACKGROUND AND OBJECTIVE: The aim of our study was to study the association of insulin resistance expressed by HOMA and adipokines in obese type 2 diabetic patients with or without hyper-transaminasemia. SUBJECTS AND METHODS: A population of 72 obese patients with type 2 diabetes mellitus was analyzed. HOMA-IR was calculated as indicator of insulin-resistance. Adipocytokines blood levels were measured. RESULTS: Patients were classified as group I (n=37) when serum ALT activity was normal or group II (NAFLD patients: n=35) when serum ALT activity was greater than the median value of the group (≥ 28 UI/L). In NAFLD group, BMI, weight, fat mass, waist to hip ratio, waist circumference, triglycerides, HOMA and insulin levels were higher than control group. In the logistic regression analysis with a dependent variable (ALT) and the statistical univariant variables as independent variables, the HOMA-IR remained in the model, with an Odd's ratio of 1.21 (CI:95%: 1.11-1.35) to have a high ALT level with each 1 unit of HOMA-IR adjusted by age, sex, weight, and dietary intake. CONCLUSIONS: Some metabolic parameters are associated with elevated ALT in female obese patients. However, adjusted by other variables, only insulin resistance remained associated.

A randomized clinical trial with two doses of an enteral diabetes-specific suplements in elderly patients with diabetes mellitus type 2.

OBJECTIVES: The aim of our study was to investigate whether two different daily doses of a high monounsaturated fatty acid (MUFA) specific diabetes enteral formula could improve nutritional variables as well as metabolic parameters. PATIENTS AND METHODS: We conducted a randomized, open-label, multicenter, parallel group study. 27 patients with diabetes mellitus type 2 with recent weight loss were randomized to one of two study groups: group 1 (two cans per day) and group 2 (three cans per day) for a ten week period. RESULTS: A significative decrease of HbA1c was detected in both groups. The decrease 0.98% (confidence interval 95% 0.19-1.88) was higher in group 2 than group 1 0.60% (confidence interval 95% 0.14-1.04). A significant increase of weight, body mass index, fat mass, albumin, prealbumin and transferrin was observed in both groups without statistical differences in this improvement between both groups. The increase of weight 4.59kg (confidence interval 95% 1.71-9.49) was higher in group 2 than group 1 1.46% (confidence interval 95% 0.39-2.54). Gastrointestinal tolerance (diarrhea episodes) with both formulas was good, without statistical differences (7.60% vs 7.14%: ns). CONCLUSIONS: A high monounsaturated fatty acid diabetes-specific supplement improved HbA1c and nutritional status. These improvements were higher with three supplements than with two per day.

Double blind randomized clinical trial controlled by placebo with a fos enriched cookie on saciety and cardiovascular risk factors in obese patients.

INTRODUCTION: It is essential to determine which snack foods are most affective for appetite control. The objective of the current study was to assess the responses of two different cookies on satiety and cardiovascular risk factors. MATERIAL AND METHODS: 38 patients were randomized: group I (FOS enriched cookie, n=19) and group II (control cookie, n=19). Previous and after 1 month , the subjects rated their feelings of satiety/hunger with a test meal of 5 cookies. RESULTS: After the test meal, the basal area under curve of the first hunger/satiety score was higher with satiety cookie than with control cookie, the data after 1 month of treatment was higher with satiety cookie than with control cookie, too. The score was higher than the fasting level for 20 minutes with satiety cookie and for 40 minutes with the same cookie, too. In satiety group, these scores (20 min and 40 min) were higher than control group before and after 1 month of treatment. The results were in the same way with the 100 mm 5-point visual satiety scale. Cardiovascular risk factors and dietary intake remained unchanged after dietary intervention. CONCLUSION: A FOS enriched cookie produced greater ratings of satiety than a control cookie, without effects on cardiovascular risk factors or dietary intakes.

Introducción: Es importante evaluar el papel de los alimentos tipo «snacks¼ sobre el apetito. El objetivo de este trabajo fue evaluar la respuesta en términos de saciedad y el efecto sobre factores de riesgo cardiovascular de dos galletas diferentes. Material y Métodos: Se randomizaron 38 pacientes: grupo I (galleta enriquecida en FOS, n=19) y grupo II (galleta control, n=19). Antes de la intervención nutricional y tras un mes, a los pacientes se les valoró la saciedad con un test de prueba con 5 galletas. Resultados: Tras el test de prueba, el area bajo la curva del test de saciedad fue mayor con la galleta saciante que con la galleta control, detectándose el mismo resultado con el test trás 1 mes de ingerir las galletas. Analizando los diferentes tiempos, el score de saciedad mostró una puntuación superior en los tiempos 20 y 40 minutos frente al valor basal (tiempo 0) tras la ingesta de la galleta saciante, comparado con la galleta control. Los valores de saciedad en los tiempos (20 minutos y 40 minutos) fueron superiores que los que presentó la galleta control. Este resultado fue similar, al realizar el test tras 1 mes tomando la galleta saciante. Los resultados fueron similares al utilizar una escala visual de saciedad de 100 mm con 5 cuestiones. No se detectaron efectos sobre los factores de riesgo cardiovascular tras la intervención nutricional, ni sobre la ingesta dietética global. Conclusion: La galleta enriquecida en FOS produce mayores niveles de saciedad que la galleta control. Sin embargo no existieron efectos sobre los factores de riesgo cardiovascular ni la ingesta dietética global.

[Blood glucose and insulin responses to two hypocaloric enteral formulas in patients with diabetes mellitus type 2]. / Respuesta glucémica e insulinémica a dos fórmulas enterales isocalóricas en pacientes con diabetes mellitus tipo 2.

OBJECTIVES: The aim of this study is to compare the glycaemic and insulinemic response of type 2 diabetic patients after oral administration of 250 ml of two enteral formulas: a specific formula (Novasource Diabet Smartflex) against a standard isocaloric formula. METHODS: The design was a cross-over study, with the diabetic patients (n = 15) receiving one of the two formulas in random order. Glycaemia and insulinemia curves were performed at 0, 10, 20, 30,60, 90,120,150 and 180 minutes. The variables studied were the area under the curve (AUC(0)-t), maximum concentration (Cmax), the time to reach maximum concentration (Tmax) and the concentrations of biochemical parameters in each study period. RESULTS: We studied 11 males (73.3%) and 4 females (26.7%), the mean age was 56.9 ± 10.9 years. Patients receiving Novasource Diabet showed a lower mean AUC(0)-t of glucose, mean difference - 4,753.26 mg/min/dl (95% CI: -7,256.7 to -2,249.82), also showed a mean insulinemia significantly lower AUC(0)-t, mean difference: 930.27 uU/min/ml (95% CI -1,696.34 to -164.2). The Cmax showed a significantly lower mean blood glucose levels with the specific formula, mean difference -26.89 mg/dl (95% CI -42.11 to -11.67) and insulin, mean difference: -5.39 uU/ml (95% CI: -10.37 to -1.43). The analysis shows that the mean Tmax of glucose with the specific formula are significantly lower, mean difference -19.82 min (95% CI: -32.11 to -7.33), however there was no difference in Tmax of insulin. Finally the analysis of glucose concentrations in the total study shows that the group with the specific formula has a lower mean glucose 25.77 mg / dl (95% CI 18.29 to 33.25), the same fact was detected with insulinemia 4.39 mU/ml (95% CI: 0.927 to 7.87). CONCLUSIONS: Diabetic patients treated diabet Novasource had significantly lower mean AUC0-t, Cmax and Tmax in blood glucose curves, also had lower mean AUC(0)-t and Cmax in insulin curves.

Objetivos: El objetivo del presente estudio es comparar la respuesta glucémica e insulinémica de pacientes diabéticos tipo 2 tras la administración oral de 250 ml de dos formulas enterales: una formula especifica (Novasource® Diabet Smartflex®) frente a una fórmula isocalórica estándar. Material y métodos: El diseño fue cruzado, recibiendo los pacientes diabéticos (n = 15) de manera aleatoria las dos fórmulas. Se realizó una curva de glucemia e insulinemia en los tiempos 0, 10,20, 30,60, 90, 120,150 y 180 minutos.

Los pacientes que recibieron Novasource® Diabet presentan una media menor de AUC0-t, diferencia entre medias de glucemia -4.753,26 mg/min/dl (IC 95%: -7.256,7 a -2.249,82), también presentaron una media de insulinemia significativamente menor de AUC0-t, diferencia de medias: -930,27 uU/min/ml (IC 95%: -1.696,34 a -164,2). La Cmax mostró unas medias de glucemia significativamente menores con la fórmula específica, diferencia de medias -26,89 mg/dl (IC 95% 42,11 a -11,67) e insulinemia, diferencia de medias: -5,39 uU/ml (IC 95%: -10,37 a -1,43). El análisis de Tmax muestra que las medias de glucemia con la fórmula específica son significativamente menores, diferencia de medias -19,82 min (IC 95%: -32,11 a -7,33), sin diferencia significativa en la Tmax de insulinemia. Finalmente el análisis de las concentraciones de glucosa en el total del estudio muestra que el grupo con la formula específica tiene una media menor de glucosa 25,77 mg/dl (IC 95%: 18,29 a 33,25), sucediendo lo mismo con la insulinemia 4,39 U/ml (IC 95%: 0,927 a 7,87). Conclusiones: Los pacientes diabéticos tipo 2 que recibieron Novasource® Diabet presentan significativamente menores medias de AUC0-t, Cmax y Tmx en las curvas de glucemia, también presentaron menores medias de AUC0-t y Cmax en las curvas de insulinemia.

Association of anthropometric and biochemical markers with length of stay and mortality in the hospital.

INTRODUCTION: Malnutrition is associated with patient outcome, hospital stay and costs. The objective of our study was evaluated the relationship of different anthropometric and biochemical nutritional markers with hospital stance (days) and mortality. PATIENTS AND METHODS: A sample of 3087 hospitalized patients in a Universitary Hospital was enrolled. Nutritional status was assessed from anthropometric variables; body mass index (BMI), weight, weight loss in previous three months, tricipital skin fold thickness, midarm muscle circumference and midarm muscle area. Biochemical evaluation was assessed with albumin, prealbumin, transferrin and lymphocytes. Length of hospital stance and mortality were recorded. RESULTS: A total of 3087 patients were enrolled, mean age was 67.7±18.3 years, weight 63.3±15,7 kg and BMI 23.7±6.8, with a weight loss (3 months) of 6.3±4.6 kg. Length of stay was 24.7±22.1 days. A total of 2583 patients were discharged. Hospital discharge data showed 87.8% of patients went home, and a 12.2% of patients were discharged to a secondary Hospital. A (n=504) 16.3% of patients died. In the multivariate analysis with a dependent variable [length of stay (days)], only albumin levels remained as an independent predictor in the model (F=2.9; p < 0.05), with an increase of 3.1 days in hospital stay (CI 95%: 0.4-5.8) with each decrease of 1 g/dl of albumin. In multivariate analysis, an independent factor that decrease mortality was high albumin levels (hazard ratio: 0.41; 95% CI: 0.22-0.80), adjusted by age and sex. CONCLUSIONS: Our study shows a significant association among serum albumin levels with length of stay in hospital and mortality.

Factors affecting the bioaccessibility of fluoride from seafood products.

Fluoride is considered important for health because of its beneficial effect on the prevention of dental caries and on bone development in the child population. However, excessive intake has negative effects. The main pathway for exposure is oral, through consumption of drinking water, and some food products. Therefore its bioaccessibility (quantity of the element solubilized during the digestive process) is a parameter to be considered when estimating the risk/benefit associated with this element. The aim of the present study was to evaluate the influence of the digestion phase, gastrointestinal digestion factors (pH, pepsin and bile salt concentrations) and the presence of cations on the bioaccessibility of fluoride from seafood products. The results show that the solubilization of fluoride takes place entirely during the gastric phase. Its bioaccessibility is strongly influenced by conditions that favor the formation of insoluble complexes of fluoride with other elements present in the matrix. The factors that are most influential in reducing its bioaccessibility are the increase in pH in the gastric phase, the presence of cations, especially in the intestinal phase, and a low concentration of bile salts.
