Estudio preliminar de la ingesta de nutrientes de niños deportistas de Sierra Nevada

A study was conducted of the diet of a child Alpine ski competition team (Monachil Club, Sierra Nevada). The children,aged between 7-12 years old, were divided into two groups. One of which were residents at a ski resort and the other,residents from different cities, who practised skiing at the same resort at weekends only.A 24-hour recall questionnaire was carried out, from which the following data was collected: The mean energy valuefrom diet intake was determined at 3,218 ± 819 Kcal/day (ski resort group) and 2,485 ± 600 Kcal/day (city group). Nosignificant differences between the groups was observed (p≥0.3). The distribution of energy from energetic nutrients wascorrect for the ski resort group, both at the weekend and during the week; the city group had an excessive intake oflipids (43%) and proteins (17%), and the energy from carbohydrates did not reach 55%. A modification in the diet andintake of energy and nutrients was observed when the children moved from their family home to the ski resortSe ha realizado un estudio de la dieta del equipo de competición infantil en esquí alpino (Club Monachil, SierraNevada).

Supporting Future Cannabis Policy - Developing a Standard Joint Unit: A Brief Back-Casting Exercise.

The standardization of cannabis doses is a priority for research, policy-making, clinical and harm-reduction interventions and consumer security. Scientists have called for standard units of dosing for cannabis, similar to those used for alcohol. A Standard Joint Unit (SJU) would facilitate preventive and intervention models in ways similar to the Standard Drink (SD). Learning from the SD experiences allows researchers to tackle emerging barriers to the SJU by applying modern forecasting methods. During a workshop at the Lisbon Addictions Conference 2019, a back-casting foresight method was used to address challenges and achieve consensus in developing an SJU. Thirty-two professionals from 13 countries and 10 disciplines participated. Descriptive analysis of the workshop was carried out by the organizers and shared with the participants in order to suggest amendments. Several characteristics of the SJU were defined: (1) core values: easy-to use, universal, focused on THC, accurate, and accessible; (2) key challenges: sudden changes in patterns of use, heterogeneity of cannabis compounds as well as in administration routes, variations over time in THC concentrations, and of laws that regulate the legal status of recreational and medical cannabis use); and (3) facilitators: previous experience with standardized measurements, funding opportunities, multi-stakeholder support, high prevalence of cannabis users, and widespread changes in legislation. Participants also identified three initial steps for the implementation of a SJU by 2030: (1) Building a task-force to develop a consensus-based SJU; (2) Expanded available national-level data; (3) Linking SJU consumption to the concept of "risky use," based on evidence of harms

Yeasts associated with the production of distilled alcoholic beverages

Distilled alcoholic beverages are produced firstly by fermenting sugars emanating from cereal starches (in the case of whiskies), sucrose-rich plants (in the case of rums), fructooligosaccharide-rich plants (in the case of tequila) or from fruits (in the case of brandies). Traditionally, such fermentations were conducted in a spontaneous fashion, relying on indigenous microbiota, including wild yeasts. In modern practices, selected strains of Saccharomyces cerevisiae are employed to produce high levels of ethanol together with numerous secondary metabolites (eg. higher alcohols, esters, carbonyls etc.) which greatly influence the final flavour and aroma characteristics of spirits following distillation of the fermented wash. Therefore, distillers, like winemakers, must carefully choose their yeast strain which will be very important in providing the alcohol content and the sensory profiles of spirit beverages. This Chapter discusses yeast and fermentation aspects associated with the production of selected distilled spirits and highlights similarities and differences with the production of wine

RICORS2040 : The need for collaborative research in chronic kidney disease

Chronic kidney disease (CKD) is a silent and poorly known killer. The current concept of CKD is relatively young and uptake by the public, physicians and health authorities is not widespread. Physicians still confuse CKD with chronic kidney insufficiency or failure. For the wider public and health authorities, CKD evokes kidney replacement therapy (KRT). In Spain, the prevalence of KRT is 0.13%. Thus health authorities may consider CKD a non-issue: very few persons eventually need KRT and, for those in whom kidneys fail, the problem is 'solved' by dialysis or kidney transplantation. However, KRT is the tip of the iceberg in the burden of CKD. The main burden of CKD is accelerated ageing and premature death. The cut-off points for kidney function and kidney damage indexes that define CKD also mark an increased risk for all-cause premature death. CKD is the most prevalent risk factor for lethal coronavirus disease 2019 (COVID-19) and the factor that most increases the risk of death in COVID-19, after old age. Men and women undergoing KRT still have an annual mortality that is 10- to 100-fold higher than similar-age peers, and life expectancy is shortened by ~40 years for young persons on dialysis and by 15 years for young persons with a functioning kidney graft. CKD is expected to become the fifth greatest global cause of death by 2040 and the second greatest cause of death in Spain before the end of the century, a time when one in four Spaniards will have CKD. However, by 2022, CKD will become the only top-15 global predicted cause of death that is not supported by a dedicated well-funded Centres for Biomedical Research (CIBER) network structure in Spain. Realizing the underestimation of the CKD burden of disease by health authorities, the Decade of the Kidney initiative for 2020-2030 was launched by the American Association of Kidney Patients and the European Kidney Health Alliance. Leading Spanish kidney researchers grouped in the kidney collaborative research network Red de Investigación Renal have now applied for the Redes de Investigación Cooperativa Orientadas a Resultados en Salud (RICORS) call for collaborative research in Spain with the support of the Spanish Society of Nephrology, Federación Nacional de Asociaciones para la Lucha Contra las Enfermedades del Riñón and ONT: RICORS2040 aims to prevent the dire predictions for the global 2040 burden of CKD from becoming true

Longitudinal study on the body mass index (BMI) of dialysis patients

Chronic renal failure is commonly related to hyponutrition, affecting approximately on third of patients with advanced renal failure. We carried out a longitudinal study to assess nutritional evolution of 73 patients on a regular hemodialysis program, assessing changes in the anthropometrical parameter body mass index (BMI) and its correspondence to biochemical nutritional parameters such as total protein (TP) levels and serum albumin (Alb). Every three months plasma TP and albumin levels were collected and BMI was calculated by the standard formula: post-dialysis weight in kg/height in m2. For classifying by BMI categories, overweight and low weight were defined according to the WHO Expert Committee. Studied patients had a mean age of 53 years, 43 were male and 30 were female patients. BMI in women was lower than that in men (p < 0.001), as well as TP (p < 0.001) and Alb (p < 0.001) levels. Mean BMI was 29.3 kg/m2. Three point two percent of the determinations showed low weight, 12.16% overweight, and 83.97% normal BMI. TP were normal in 90.76% and decreased in 9.24%. Alb was normal in 82.2% and low in 17.78%. After the follow-up time (21.6 months, minimum 18 months, maximum 53 months), the Kruskal-Wallis test did not show a statistically significant change for BMI but it did show a change for the biochemical parameters albumin and total proteins (p < 0.05): nutritional impairment in CRF patients is manifested on biochemical parameters (TP and Alb) with no reflection on anthropometrical data.YesLa insuficiencia renal crónica está relacionada frecuentemente con la malnutrición, afectando aproximadamente a un tercio de los pacientes con enfermedad renal avanzada. Realizamos un estudio longitudinal de la evolución nutricional de 73 pacientes en programa de hemodiálisis periódica, valorando las modificaciones del parámetro antropométrico de índice de masa corporal (IMC) y su correspondencia con parámetros nutricionales bioquímicos como son proteínas totales (PT) y albúmina sérica (Alb). Trimestralmente se recogieron los niveles plasmáticos de PT y Alb, y se evaluó su IMC calculado por la fórmula Standard: peso postdiálisis en Kg / altura m2 . Para la clasificación en grupos según el IMC, sobrepeso y bajo peso fueron definidos según los valores del Comité de Expertos de la OMS. Los pacientes estudiados presentan una edad media de 53 años, 43 eran varones y 30 mujeres. El IMC de las mujeres fue inferior al de los varones (p<0,001), así como los niveles de PT (p<0,001) y Alb (p<0,001). El IMC medio es de 29,3 Kg/m2 . El 3,2% de las determinaciones mostraban bajo peso, 12,16% sobrepeso y el 83,97 % un IMC normal. Las PT eran normales en el 90,76% y disminuidas en el 9,24%, la Alb normal en el 82,2% y baja en el 17,78%.Tras el tiempo de seguimiento (21,6 meses, con mínimo de 18 meses y máximo de 53) el Test de Kruskal-Wallis no mostró variación estadísticamente significativa en IMC y sí en los parámetros bioquímicos albúmina y proteínas totales (p<0,05): el deterioro nutricional de los pacientess con IRC en programa de diálisis se manifiesta en los parámetros bioquímicos (PT y Alb) sin que se refleje en los datos antropométricos

Prevalencia de diabetes en una población con cáncer de un hospital de Málaga.

Journal Article;BACKGROUND There are multiple risk factors for cancer, including obesity, sedentary lifestyle, diabetes (DM). Hormon Insulin is a growth factor that promotes cellular differentiation. AIMS The aim of our study is to observe impaired glycaemia in cancer population compared with control. METHODS We studied the prevalence of diabetes (DM) and impaired fasting glycaemia (IFG) in 374 patients with different types of cancer before treatment, by medical records in a Malaga hospital (Spain). We compared the prevalence of basal hyperglycaemia in these patients with general population, within an age range and by gender. RESULTS AND DISCUSSION The prevalence of diabetes was 32.35% in our cancer patients. The comparison depends of age range, and by gender prevalence was: 45-54 years, DM: 40.91% in men cases, versus (vs.) 14.5% in men control (p = 0.005). 55-64 years, IFG: 23.08% in women cases, vs. 5.9% in women control (p = 0.001). 65-74 years, DM: 47.13% in men cases, vs. 25.4% in men control (p = 0.000), and IFG: 23.81% in women cases, vs. 9.5% in women control (p = 0.019). We found a higher prevalence of diabetes in specific types of cancer such as prostate (p < 0.005). Moreover, men had a higher prevalence of diabetes or less diabetes control than women in our cancer sample. CONCLUSIONS We recommend an OGTT (oral glucose tolerance test) for better diagnosis of possible DM in patients with cancer, and an appropriate treatment. It may be an independent risk factor for cancer to have decreased insulin activity, or DM.YesIntroducción: Existen múltiples factores de riesgo para que una célula degenere en crecimiento indiferenciado o cáncer. Entre otros factores se ha observado que la obesidad, el sedentarismo y la diabetes aumentan este riesgo. La insulina es un factor de crecimiento que promueve la diferenciación celular. Objetivos: El objetivo de nuestro estudio es observar la glucemia basal en una población con cáncer y comparar con una población control. Métodos: Estudiamos la presencia de diabetes mellitus (DM) y de glucosa alterada en ayunas (GAA) en 374 pacientes de distintos tipos de cáncer mediante sus historiales observando la glucemia basal del ingreso antes de su tratamiento. Comparamos con la glucemia basal en población normal por rangos de edad y sexo. Resultados y discusión: La prevalencia de diabetes en los pacientes con cáncer fue de 32,35%. Comparación por sexo y rangos de edad: observamos que entre 45-54 años, DM: 40,91% en hombres cancerosos versus (vs) 14.5% en hombres control (p = 0,005). Entre 55-64 años, GAA: 23,08% en mujeres cancerosas vs 5,9% en mujeres control (p = 0001). Entre 65-74 años, DM: 47,13% en hombres cancerosos vs 25,4% en hombres control (p = 0,000), y GAA: 23,81% en mujeres cancerosas vs 9,5% en mujeres control (p = 0,019). Encontramos una mayor prevalencia de diabetes en unos tipos específicos de cáncer más que en otros, como por ejemplo en el cáncer de próstata (p < 0,005). Así mismo observamos que los hombres tienen una mayor prevalencia de diabetes o un menor control de la enfermedad que las mujeres en nuestra muestra de casos de cáncer. Conclusiones: Recomendamos un diagnóstico sistemático de diabetes en los pacientes con cáncer mediante test de tolerancia oral de glucosa (OGTT) y su conveniente tratamiento. Es posible que la diabetes, o el tener disminuida la actividad insulínica, sea un factor más de riesgo para el cáncer

Evolución de parámetros bioquímicos nutricionales en pacientes de hemodiálisis durante un año de seguimiento Evolution of nutritional biochemical parameters in hemodialysis patients during a one-year follow-up period

La elevada supervivencia actual del paciente en hemodiálisis (52% hasta 5 años), ha hecho que se pongan de manifiesto complicaciones crónicas como la elevada prevalencia de malnutrición en los enfermos, así como la importancia de la situación nutricional en la morbi-mortalidad que presentan. La causa de desnutrición proteico-calórica es multifactorial, aunque procesos de inflamación crónica asociada a la técnica de diálisis cobran cada vez más relevancia. Se han evaluado las variaciones de distintos parámetros bioquímicos nutricionales (proteínas totales, albúmina plasmática, transferrina y colesterol total) de 73 pacientes en hemodiálisis durante un año de seguimiento. La edad media de los pacientes era de 53,3 &plusmn; 18,69 años, con 43 varones y 30 mujeres. El tiempo en programa de hemodiálisis ha sido de 43 &plusmn; 33 meses, con una duración media de la sesión de 246&plusmn; 24 minutos y dosis media de hemodiálisis administrada de 1,37 &plusmn; 0,27 (KT/V) (Daurgidas 2ª generación). Se ha observado un descenso en todos los parámetros bioquímicos evaluados, con diferencias estadísticamente significativas: Proteínas totales (p Current high survival in hemodialysis patients (52% at 5 years) have made the chronic manifestations to emerge such as the high hyponutrition prevalence of these patients, as well as the importance of the nutritional status in their morbimortality. The reason for protein-caloric hyponutrition is multifactorial, although chronic inflammatory conditions associated to the dialysis technique are becoming more and more relevant. The variations in several nutritional biochemical parameters (total proteins, plasma albumin, transferrin, and total cholesterol) have been assessed in 73 hemodialysis patients for one year. The mean age of the patients was 53.3 &plusmn; 18.69 years (43 males and 30 females). The average on hemodialysis program was 43 &plusmn; 33 months, with a mean session duration of 246 &plusmn; 24 minutes, and mean hemodialysis dose administered of 1.37 &plusmn; 0.27 (KT/V) (second generation Daurgidas). A decrease in all the biochemical parameters assessed has been observed, with statistically significant differences: total proteins (p < 0.001), albumin (p < 0.00001), total cholesterol (p < 0.05), and transferrin (p < 0.01). The evolution of the nutritional biochemical parameters assessed showed an important nutritional deterioration of the patients remaining stable with the therapy
