Physical activity patterns in type 1 diabetes in Spain: The SED1 study.

AIMS: To describe the physical activity (PA) frequency and intensity in the Spanish type 1 diabetes mellitus (T1D) population and its association with their glycemic control. METHODS: A cross-sectional observational study was carried out in 75 Spanish public hospitals (the SED1 study). T1D patients over 14years of age self-completed the International Physical Activity Questionnaire (IPAQ) to determine their level of exercise. The relationship between PA frequency and intensity in T1D patients and glycemic control and the diabetes therapeutic education received were analyzed. RESULTS: A total of 592 patients were evaluable. A 6.8% of the sample performed light PA, 20.9% moderate and 72.3% vigorous. Estimated PA presented a high inter-individual variability. Men consumed more energy (METS) than women, these differences being more noticeable in vigorous METS (2865.80 in men vs 1352.12 in women). Women invested more min/week in the domestic and garden area (639.03 vs 344.39, p = 0,022). A correlation between glycemic control and the METs was not observed. CONCLUSIONS: The Spanish T1D population performed PA in a higher frequency and intensity than the general population. A relationship between PA and glycemic control couldn´t be shown. However, limitations of the study should be kept in mind to discard a long-term positive influence.

Evaluating remote facilitation intensity for multi-national translation of nurse-initiated stroke protocols (QASC Australasia): a protocol for a cluster randomised controlled trial.

BACKGROUND: Facilitated implementation of nurse-initiated protocols to manage fever, hyperglycaemia (sugar) and swallowing difficulties (FeSS Protocols) in 19 Australian stroke units resulted in reduced death and dependency for stroke patients. However, a significant gap remains in translating this evidence-based care bundle protocol into standard practice in Australia and New Zealand. Facilitation is a key component for increasing implementation. However, its contribution to evidence translation initiatives requires further investigation. We aim to evaluate two levels of intensity of external remote facilitation as part of a multifaceted intervention to improve FeSS Protocol uptake and quality of care for patients with stroke in Australian and New Zealand acute care hospitals. METHODS: A three-arm cluster randomised controlled trial with a process evaluation and economic evaluation. Australian and New Zealand hospitals with a stroke unit or service will be recruited and randomised in blocks of five to one of the three study arms-high- or low-intensity external remote facilitation or a no facilitation control group-in a 2:2:1 ratio. The multicomponent implementation strategy will incorporate implementation science frameworks (Theoretical Domains Framework, Capability, Opportunity, Motivation - Behaviour Model and the Consolidated Framework for Implementation Research) and include an online education package, audit and feedback reports, local clinical champions, barrier and enabler assessments, action plans, reminders and external remote facilitation. The primary outcome is implementation effectiveness using a composite measure comprising six monitoring and treatment elements of the FeSS Protocols. Secondary outcome measures are as follows: composite outcome of adherence to each of the combined monitoring and treatment elements for (i) fever (n=5); (ii) hyperglycaemia (n=6); and (iii) swallowing protocols (n=7); adherence to the individual elements that make up each of these protocols; comparison for composite outcomes between (i) metropolitan and rural/remote hospitals; and (ii) stroke units and stroke services. A process evaluation will examine contextual factors influencing intervention uptake. An economic evaluation will describe cost differences relative to each intervention and study outcomes. DISCUSSION: We will generate new evidence on the most effective facilitation intensity to support implementation of nurse-initiated stroke protocols nationwide, reducing geographical barriers for those in rural and remote areas.

Fatty liver index as a predictor for type 2 diabetes in subjects with normoglycemia in a nationwide cohort study.

Our aim was to evaluate whether fatty liver index (FLI) is associated with the risk of type 2 diabetes (T2DM) development within the Spanish adult population and according to their prediabetes status; additionally, to examine its incremental predictive value regarding traditional risk factors. A total of 2260 subjects (Prediabetes: 641 subjects, normoglycemia: 1619 subjects) from the Di@bet.es cohort study were studied. Socio-demographic, anthropometric, clinical data and survey on habits were recorded. An oral glucose tolerance test was performed and fasting determinations of glucose, lipids and insulin were made. FLI was calculated and classified into three categories: Low (< 30), intermediate (30-60) and high (> 60). In total, 143 people developed diabetes at follow-up. The presence of a high FLI category was in all cases a significant independent risk factor for the development of diabetes. The inclusion of FLI categories in prediction models based on different conventional T2DM risk factors significantly increase the prediction power of the models when all the population was considered. According to our results, FLI might be considered an early indicator of T2DM development even under normoglycemic condition. The data also suggest that FLI could provide additional information for the prediction of T2DM in models based on conventional risk factors.

Rabdomiólisis en un paciente con enfermedad de McArdle / Rhabdomyolysis in a patient with McArdle's disease

INTRODUCCIÓN: La enfermedad de McArdle o glucogenosis tipo V es una enfermedad rara debida al déficit de miofosforilasa muscular, lo que produce incapacidad para degradar el glucógeno a este nivel. Los pacientes presentan fatiga, dolor y calambres de forma habitual. Además, tras un ejercicio intenso o situación estresante, están expuestos a lisis celular. Esto se puede manifestar en forma de mioglobinuria y rabdomiólisis, síndrome clínico potencialmente grave si no se trata con rapidez. VALORACIÓN: Se presenta el caso de un varón de 38 años con enfermedad de McArdle y rabdomiólisis secundaria a la realización de ejercicio, que precisó atención en el Servicio de Urgencias durante 24 horas, así como su posterior ingreso en Unidad de Hospitalización. Se realizó una valoración enfermera siguiendo el modelo de cuidados de Virginia Henderson. DIAGNÓSTICO: Se priorizaron los diagnósticos enfermeros: (00016) deterioro de la eliminación urinaria, (00092) intolerancia a la actividad, (00093) fatiga y (00132) dolor agudo; y la complicación potencial: riesgo de fallo renal agudo. PLANIFICACIÓN: Se elabora Plan de Cuidados siguiendo la metodología NANDA-NIC-NOC, con especial atención a las alteraciones en la eliminación y en el sistema musculoesquelético. Se realiza monitorización de la diuresis. Se realiza reposición de líquidos y se administra medicación analgésica. DISCUSIÓN: Existe escasa literatura sobre los cuidados enfermeros de pacientes con enfermedad de McArdle, lo que ha limitado la comparación de nuestros resultados con los de otros autores, sin embargo, dada la buena respuesta del sujeto mediante reposición de líquidos, un óptimo control del dolor y el reposo demostraron una rápida recuperación del paciente

INTRODUCTION: McArdle's disease or glycogenosis type V is a rare disease due to deficiency of muscle myophosphorylase leading to inability to degrade glycogen at this level. Patients have fatigue, pain, and cramps on a regular basis. In addition, after intense exercise or stressful situation, they are exposed to cellular lysis. This can occur in the form of rhabdomyolysis and myoglobinuria, a potentially serious clinical syndrome if not treated quickly. CASE EVALUATION: We present the care plan of a 38-year-old man with McArdle's disease and secondary rhabdomyolysis on physical exercise, which required attention in the Emergency Department for 24 hours, as well as his subsequent admission to the ward. A nursing evaluation was performed following the care model of Virginia Henderson. DIAGNOSIS: Priority was given to nurse diagnoses: (00016) deterioration of urinary elimination, (00092) activity intolerance, (00093) fatigue and (00132) acute pain; and potential complication: risk of acute renal failure. PLANNING: The Care Plan is developed following the NANDA-NIC-NOC methodology, with special attention to alterations in the elimination and musculoskeletal system. The diuresis is monitored. Fluid replenishment is performed, and analgesic medication is given. DISCUSSION: There is little literature on the nursing care of patients with McArdle's disease, which has limited the comparison of our results with those of other authors. However, given the good response of the subject through fluid replacement, optimal pain control and rest, they made a rapid recovery

Incidence of diabetes mellitus in Spain as results of the nation-wide cohort di@bet.es study.

Our aim was to determine the incidence of type 2 diabetes mellitus in a nation-wide population based cohort from Spain (di@bet.es study). The target was the Spanish population. In total 5072 people older than 18 years,were randomly selected from all over Spain). Socio-demographic and clinical data, survey on habits (physical activity and food consumption) and weight, height, waist, hip and blood pressure were recorder. A fasting blood draw and an oral glucose tolerance test were performed. Determinations of serum glucose were made. In the follow-up the same variables were collected and HbA1c was determined. A total of 2408 subjects participated in the follow-up. In total, 154 people developed diabetes (6.4% cumulative incidence in 7.5 years of follow-up). The incidence of diabetes adjusted for the structure of age and sex of the Spanish population was 11.6 cases/1000 person-years (IC95% = 11.1-12.1). The incidence of known diabetes was 3.7 cases/1000 person-years (IC95% = 2.8-4.6). The main risk factors for developing diabetes were the presence of prediabetes in cross-sectional study, age, male sex, obesity, central obesity, increase in weight, and family history of diabetes. This work provides data about population-based incidence rates of diabetes and associated risk factors in a nation-wide cohort of Spanish population.

Legumes display common and host-specific responses to the rhizobial cellulase CelC2 during primary symbiotic infection.

Primary infection of legumes by rhizobia involves the controlled localized enzymatic breakdown of cell walls at root hair tips. Previous studies determined the role of rhizobial CelC2 cellulase in different steps of the symbiotic interaction Rhizobium leguminosarum-Trifolium repens. Recent findings also showed that CelC2 influences early signalling events in the Ensifer meliloti-Medicago truncatula interaction. Here, we have monitored the root hair phenotypes of two legume plants, T. repens and M. sativa, upon inoculation with strains of their cognate and non-cognate rhizobial species, R. leguminosarum bv trifolii and E. meliloti, (over)expressing the CelC2 coding gene, celC. Regardless of the host, CelC2 specifically elicited 'hole-on-the-tip' events (Hot phenotype) in the root hair apex, consistent with the role of this endoglucanase in eroding the noncrystalline cellulose found in polarly growing cell walls. Overproduction of CelC2 also increased root hair tip redirections (RaT phenotype) events in both cognate and non-cognate hosts. Interestingly, heterologous celC expression also induced non-canonical alterations in ROS (Reactive Oxygen Species) homeostasis at root hair tips of Trifolium and Medicago. These results suggest the concurrence of shared unspecific and host-related plant responses to CelC2 during early steps of symbiotic rhizobial infection. Our data thus identify CelC2 cellulase as an important determinant of events underlying early infection of the legume host by rhizobia.

Iodine status and thyroid function among Spanish schoolchildren aged 6-7 years: the Tirokid study.

I deficiency is still a worldwide public health problem, with children being especially vulnerable. No nationwide study had been conducted to assess the I status of Spanish children, and thus an observational, multicentre and cross-sectional study was conducted in Spain to assess the I status and thyroid function in schoolchildren aged 6-7 years. The median urinary I (UI) and thyroid-stimulating hormone (TSH) levels in whole blood were used to assess the I status and thyroid function, respectively. A FFQ was used to determine the consumption of I-rich foods. A total of 1981 schoolchildren (52 % male) were included. The median UI was 173 µg/l, and 17·9 % of children showed UI<100 µg/l. The median UI was higher in males (180·8 v. 153·6 µg/l; P<0·001). Iodised salt (IS) intake at home was 69·8 %. IS consumption and intakes of ≥2 glasses of milk or 1 cup of yogurt/d were associated with significantly higher median UI. Median TSH was 0·90 mU/l and was higher in females (0·98 v. 0·83; P<0·001). In total, 0·5 % of children had known hypothyroidism (derived from the questionnaire) and 7·6 % had TSH levels above reference values. Median TSH was higher in schoolchildren with family history of hypothyroidism. I intake was adequate in Spanish schoolchildren. However, no correlation was found between TSH and median UI in any geographical area. The prevalence of TSH above reference values was high and its association with thyroid autoimmunity should be determined. Further assessment of thyroid autoimmunity in Spanish schoolchildren is desirable.

Efectividad de una intervención escolar contra la obesidad / Effectiveness of a school-based program to prevent obesity

INTRODUCCIÓN: Las intervenciones sobre la obesidad infantil son una prioridad para la salud pública. El objetivo de este estudio fue evaluar la efectividad de un programa de intervención contra la obesidad en un colegio de Educación Primaria. MATERIAL Y MÉTODOS: Estudio de intervención controlado no aleatorizado en alumnos de primero a quinto cursos de Educación Primaria en 2 colegios públicos de Avilés (España). La intervención se desarrolló durante 2 cursos escolares, incluyendo talleres sobre alimentación saludable, charlas educativas, material informativo escrito y promoción de la actividad física. La variable de resultado principal fue la puntuación z del índice de masa corporal (IMC). Como variables de resultado secundarias se consideraron: prevalencia de obesidad y sobrepeso, perímetro abdominal, hábitos de dieta y actividad física. RESULTADOS: Fueron incluidos en el estudio 382 (177 niñas, 205 niños) de 526 alumnos de ambos colegios. En 340 individuos se obtuvieron datos antropométricos completos. A diferencia del grupo control, los pertenecientes al grupo de intervención disminuyeron la puntuación z del IMC desde 1,14 a 1,02 (p = 0,017), mejoraron el índice KIDMED de adhesión a la dieta mediterránea de 7,33 a 7,71 puntos (p = 0,045) y aumentaron la proporción de estudiantes con una dieta óptima del 42,6% al 52,3% (p = 0,021). No se encontraron diferencias estadísticamente significativas en la prevalencia de obesidad y sobrepeso, ni en el perímetro abdominal, entre los grupos de intervención y control. CONCLUSIONES: Este programa escolar consiguió pequeñas mejoras en el IMC y la calidad de la dieta

INTRODUCTION: Intervention for childhood obesity is a public health priority. The purpose of this study was to evaluatethe effectiveness of an elementary school-based intervention against obesity in children. MATERIAL AND METHODS: Non-randomised controlled trial was conducted on children from first to fifth grade from two public schools of Avilés (Spain). The intervention lasted for 2 school years comprising healthy diet workshops, educational chats, educational meetings, informative written material, and promotion of physical activities. Primary outcome measure was body mass index z-score. Secondary outcomes included: obesity and overweight prevalence, waist circumference, dietary habits, and physical activity. RESULTS: A total of 382 (177 girls, 205 boys) out of 526 pupils of both schools were included in the study. Complete anthropometric data were obtained in 340 of the 382 individuals.

New methodology for assessing the environmental burden of cement mortars with partial replacement of coal bottom ash and fly ash.

This paper assess the mechanical an environmental behaviour of cement mortars manufactured with addition of fly ash (FA) and bottom ash (BA), as partial cement replacement (10%, 25% and 35%). The environmental behaviour was studied by leaching tests, which were performed under several temperature (23 °C and 60 °C) and pH (5 and 10) conditions, and ages (1, 2, 4 and 7 days). Then, the accumulated amount of the different constituents leached was analysed. In order to obtain an environmental burden (EB) value of each cement mixture, a new methodology was developed. The EB value obtained is related to the amount leached and the hazardous level of each constituent. Finally, the integral study of compressive strength and EB values of cement mixtures allowed their classification. The results showed that mortars manufactured with ordinary Portland cement (OPC) and with coal BA had similar or even better environmental and mechanical behaviour than mortars with FA. Therefore, the partial replacement of cement by BA might be as suitable or even better as the replacement by FA.

Mediterranean diet adherence in individuals with prediabetes and unknown diabetes: the Di@bet.es Study.

BACKGROUND AND AIMS: Mediterranean diet (MedDiet) is causally related to diabetes and is a dietary pattern recommended to individuals with diabetes. We investigated MedDiet adherence in individuals with prediabetes and unknown (PREDM/UKDM) or known diabetes (KDM) compared to those with normal glucose metabolism (NORMAL). METHODS: This was a national, population-based, cross-sectional, cluster-sampling study. MedDiet adherence was scored (MedScore, mean ± SD 24 ± 5) using a qualitative food frequency questionnaire. Logistic regression was used to examine the association between MedScore and PREDM/UKDM or KDM versus control subjects. RESULTS: We evaluated 5,076 individuals. Mean age was 50 years, 57% were female, 826 (582/244) were PREDM/UKDM, 478 were KDM and 3,772 were NORMAL. Mean age increased across MedScore tertiles (46, 51 and 56 years, p < 0.0001). Higher age-adjusted adherence to MedDiet (5-unit increment in the MedScore) was associated with lower and nondifferent odds (OR, 95% CI) of prevalent PREDM/UKDM (0.88, 0.81-0.96, p = 0.001) and KDM (0.97, 0.87-1.07, p = 0.279), respectively, compared to individuals in the NORMAL group. CONCLUSIONS: In a representative sample of the whole Spanish population, MedDiet adherence is independently associated with PREDM/UKDM. Therapeutic intervention may be, in part, responsible for the lack of differences in adherence observed between the KDM and NORMAL groups. However, reverse causation bias cannot be ruled out in cross-sectional studies.

Olive oil has a beneficial effect on impaired glucose regulation and other cardiometabolic risk factors. Di@bet.es study.

BACKGROUND: Despite the marked increase in cardiovascular risk factors in Spain in recent years, the prevalence and incidence of cardiovascular diseases have not risen as expected. Our objective is to examine the association between consumption of olive oil and the presence of cardiometabolic risk factors in the context of a large study representative of the Spanish population. SUBJECTS AND METHODS: A population-based, cross-sectional, cluster sampling study was conducted. The target population was the whole Spanish population. A total of 4572 individuals aged ≥ 18 years in 100 clusters (health centers) were randomly selected with a probability proportional to population size. The main outcome measures were clinical and demographic structured survey, lifestyle survey, physical examination (weight, height, body mass index, waist, hip and blood pressure) and oral glucose tolerance test (OGTT) (75 g). RESULTS: Around 90% of the Spanish population use olive oil, at least for dressing, and slightly fewer for cooking or frying. The preference for olive oil is related to age, educational level, alcohol intake, body mass index and serum glucose, insulin and lipids. People who consume olive oil (vs sunflower oil) had a lower risk of obesity (odds ratio (OR)=0.62 (95% confidence interval (CI)=0.41-0.93, P=0.02)), impaired glucose regulation (OR=0.49 (95% CI=0.28-0.86, P=0.04)), hypertriglyceridemia (OR=0.53 (95% CI=0.33-0.84, P=0.03)) and low HDL cholesterol levels (OR=0.40 (95% CI=0.26-0.59, P=0.0001)). CONCLUSIONS: The results show that consumption of olive oil has a beneficial effect on different cardiovascular risk factors, particularly in the presence of obesity, impaired glucose tolerance or a sedentary lifestyle.

Polymorphisms in HIF-1 alpha affect presence of lymph node metastasis and can influence tumor size in squamous-cell carcinoma of the glottic larynx

BACKGROUND: HIF-1alpha plays a key role in the development and progression of cancer. Its polymorphic variants C1772T and G1790A have been associated with greater susceptibility to cancer and increased tumor progression. METHODS: We determined the distribution of these polymorphisms among 121 patients with glottic cancer and 154 healthy volunteers by PCR-RFLP. We also analyzed the relationship between the presence of these polymorphisms and various clinicopathologic variables. RESULTS: Advanced tumors (T3-T4) were associated with the TT variant (p = 0.036), which was present in 75 % of T4 tumors (p = 0.008). Among patients with nodal metastasis (N+), 41.7 and 22 % were carrying the TT and GA variants, respectively, compared with 9.4 and 2 % of the patients with no metastasis (N0), (p = 0.006 and p = 0.032). CONCLUSIONS: The presence of the TT and GA variants were associated with lymph node metastasis, while the presence of the TT variant can be associated with larger tumor size (AU)

Evaluation of Health-Related Quality of Life according to Carbohydrate Metabolism Status: A Spanish Population-Based Study (Di@bet.es Study).

Objective. To evaluate the association between diabetes mellitus and health-related quality of life (HRQOL) controlled for several sociodemographic and anthropometric variables, in a representative sample of the Spanish population. Methods. A population-based, cross-sectional, and cluster sampling study, with the entire Spanish population as the target population. Five thousand and forty-seven participants (2162/2885 men/women) answered the HRQOL short form 12-questionnaire (SF-12). The physical (PCS-12) and the mental component summary (MCS-12) scores were assessed. Subjects were divided into four groups according to carbohydrate metabolism status: normal, prediabetes, unknown diabetes (UNKDM), and known diabetes (KDM). Logistic regression analyses were conducted. Results. Mean PCS-12/MCS-12 values were 50.9 ± 8.5/ 47.6 ± 10.2, respectively. Men had higher scores than women in both PCS-12 (51.8 ± 7.2 versus 50.3 ± 9.2; P < 0.001) and MCS-12 (50.2 ± 8.5 versus 45.5 ± 10.8; P < 0.001). Increasing age and obesity were associated with a poorer PCS-12 score. In women lower PCS-12 and MCS-12 scores were associated with a higher level of glucose metabolism abnormality (prediabetes and diabetes), (P < 0.0001 for trend), but only the PCS-12 score was associated with altered glucose levels in men (P < 0.001 for trend). The Odds Ratio adjusted for age, body mass index (BMI) and educational level, for a PCS-12 score below the median was 1.62 (CI 95%: 1.2-2.19; P < 0.002) for men with KDM and 1.75 for women with KDM (CI 95%: 1.26-2.43; P < 0.001), respectively. Conclusion. Current study indicates that increasing levels of altered carbohydrate metabolism are accompanied by a trend towards decreasing quality of life, mainly in women, in a representative sample of Spanish population.

Iodine intake in the adult population. Di@bet.es study.

BACKGROUND & AIMS: To date no nation-wide study has yet been undertaken in Spain to estimate the iodine deficiency. The aim was to evaluate iodine intake and its conditioning factors in a representative sample of the whole adult population. METHODS: The Di@bet.es Study is a national, cross-sectional, population-based survey conducted in 2009-2010 in Spain. RESULTS: The median urinary iodine (UI) was 117.2 µg/L. Iodized salt (IS) was consumed by 43.9% of the population. The median UI in those who consumed IS and in those who did not consume IS was 131.1 and 110.8 µg/L respectively (p<0.0001). The likelihood of having UI levels above 100 µg/L was significantly associated with the intake of IS (OR=1.47) and milk at least once a day (OR=1.22). Within each individual autonomous communities, the median UI levels in those who consumed IS correlated significantly with the median levels of those who did not consume IS (r=0.76, p=0.001). CONCLUSIONS: Though strictly speaking, Spain should be considered within the category of a country having an adequate iodine intake, the current value is too close to the cut point and does not guarantee that those groups with a greater need for iodine will have the required intake of iodine.

Prevalence of diabetes mellitus and impaired glucose regulation in Spain: the Di@bet.es Study.

AIMS/HYPOTHESIS: The Di@bet.es Study is the first national study in Spain to examine the prevalence of diabetes and impaired glucose regulation. METHODS: A population-based, cross-sectional, cluster sampling study was carried out, with target population being the entire Spanish population. Five thousand and seventy-two participants in 100 clusters (health centres or the equivalent in each region) were randomly selected with a probability proportional to population size. Participation rate was 55.8%. Study variables were a clinical and demographic structured survey, lifestyle survey, physical examination (weight, height, BMI, waist and hip circumference, blood pressure) and OGTT (75 g). RESULTS: Almost 30% of the study population had some carbohydrate disturbance. The overall prevalence of diabetes mellitus adjusted for age and sex was 13.8% (95% CI 12.8, 14.7%), of which about half had unknown diabetes: 6.0% (95% CI 5.4, 6.7%). The age- and sex-adjusted prevalence rates of isolated impaired fasting glucose (IFG), isolated impaired glucose tolerance (IGT) and combined IFG-IGT were 3.4% (95% CI 2.9, 4.0%), 9.2% (95% CI 8.2, 10.2%) and 2.2% (95% CI 1.7, 2.7%), respectively. The prevalence of diabetes and impaired glucose regulation increased significantly with age (p < 0.0001), and was higher in men than in women (p < 0.001). CONCLUSIONS/INTERPRETATION: The Di@bet.es Study shows, for the first time, the prevalence rates of diabetes and impaired glucose regulation in a representative sample of the Spanish population.
