Irisin, in women and men: blood pressure, heart rate, obesity and insulin resistance.

Background: Irisin is a myokine that increases with leisure time physical activity (LTPA) and for which a cardiovascular protective role has been postulated. Our aim was to assess this role in the general population. Methods: A cross-sectional analysis was performed in a large randomly selected population sample (n=2298 women and 1529 men). Apart from age and sex, we record anthropometrics (blood pressure, heart rate, obesity), lifestyle (LTPA, smoking, alcohol), and biochemical measurements (irisin, lipid profile, insulin resistance). Correlations and regression multivariate models were used to analyze the association of irisin levels with the studied factors. Results: The variables more strongly and directly associated with irisin, adjusting the studied factors separately in women and men, were HOMA-2 (p=0.043 and p=0.001, respectively) and LTPA (p<0.001 and p=0.001, respectively). Also heart rate inversely (p=0.005 and p=0.002, respectively) and DBP directly (p<0.005 and p=0.045, respectively) were associated to irisin in both sexes. The waist/height ratio (p<0.001) was inversely associated to irisin only in women, and the alcohol drinking was directly associated (p=0.029) only in men. Conclusion: We provide new findings for irisin, such as its association with DBP and with heart rate; furthermore, in women irisin is associated to abdominal obesity, and in men is associated to the alcohol intake. We also corroborate the association of irisin with LTPA and insulin resistance. The associations detected point towards a protective role of irisin in the maintenance of cardiometabolic health.

Adherence to the Mediterranean diet and waist-to-hip ratio in middle-aged postmenopausal women are the main factors associated with semantic verbal fluency 12 years later.

Few studies have analized the effect of vascular risk factors and lifestyle habits affecting the middle age of postmenopausal women on later cognitive performance in old age. We have carried out an observational study to identify those factors and whether they differ from those acting in men. Postmenopausal women and males, both aged 40-60 years old at recruitment, from a community dwelling cohort were included. Data for this study were collected from the first visit at recruitment (2001 to 2005). Participants were interviewed with a questionnaire on their health-related antecedents and underwent a physical exam. The cohort was contacted again for a new presential visit between 2014 and 2015. A semantic verbal fluency test was included in this new visit protocol as a brief measure of cognition. Besides educational attainment, Mediterranean diet adherence 20th percentile (OR = 1.93; 95%CI = 1.07-3.47) and waist to hip ratio 80th percentile (OR = 1.81; 95%CI = 1.10-2,98) were the main factors associated to low semantic fluency performance in postmenopausal women, while declared diabetes mellitus (OR = 2.24; 95%CI = 1.16-4,33), HOMA 2 insulin resistance index (OR = 1.77; 95%CI =1.04-3,02), light physical activity in leisure time (OR = 0.41; 95%CI = 0.19-0,93) and recommended moderate to vigorous physical activity (OR = 2.09; 95%CI = 1.23-3.56) did in men. Factors in middle age that explain semantic verbal fluency in old age are different between postmenopausal women and men. Menopause related fat redistribution may be a precondition for other vascular risk factors. The effect of Mediterranean diet on cognition deserves new specific studies centered on postmenopausal women as group.

Digging into the admixture strata of current-day Canary Islanders based on mitogenomes.

The conquest of the Canary Islands by Europeans began at the beginning of the 15th century and culminated in 1496 with the surrender of the aborigines. The collapse of the aboriginal population during the conquest and the arrival of settlers caused a drastic change in the demographic composition of the archipelago. To shed light on this historical process, we analyzed 896 mitogenomes of current inhabitants from the seven main islands. Our findings confirm the continuity of aboriginal maternal contributions and the persistence of their genetic footprints in the current population, even at higher levels (>60% on average) than previously evidenced. Moreover, the age estimates for most autochthonous founder lineages support a first aboriginal arrival to the islands at the beginning of the first millennium. We also revealed for the first time that the main recognizable genetic influences from Europe are from Portuguese and Galicians.

Cross-mapping medical records to NANDA-I to identify nursing diagnoses in a vulnerable population.

PURPOSE: To assess the association between vulnerable populations and nursing care needs, using NANDA-I diagnostics, in the population of the Canary Islands, Spain. METHODS: Nursing social epidemiology study. Cross Mapping of Medical Records to NANDA-I to Identify Nursing Diagnoses in a Population usinga medical, epidemiological follow-up study of a cohort of 7,190 people. The level of vulnerability of the participants was assigned, among those who were also assigned nursing diagnoses, using the "ICE index" to calculate the expected associations. FINDINGS: The most prevalent nursing diagnosis in our sample was Sedentary lifestyle (60.5%), followed by Ineffective health self-management (33.8%) and Risk-prone health behaviour (28.7%). Significant differences were found by sex, age group and social class, with the nursing diagnoses included in the study being more prevalent among the most socio-economically disadvantaged social class. CONCLUSIONS: The cross-mapping method is useful to generate diagnostic information in terms of care needs, using the NANDA-I classification. The expected associations between high social vulnerability and care needs have been verified in a comprehensive and representative sample of the Canarian population (Spain). IMPLICATIONS FOR NURSING PRACTICE: From an epidemiological perspective, identifying nursing diagnoses at the population level allows us to find the most prevalent needs in the different community groups and to focus appropriate nursing interventions for their implementation and impact assessment.

OBJETIVO: Evaluar la asociación entre las poblaciones vulnerables y las necesidades de cuidados de enfermería, utilizando la clasificación diagnóstica NANDA-I, en la población de las Islas Canarias, España. MÉTODOS: Estudio de epidemiología social enfermera. Mapeo cruzado de registros médicos con la clasificación NANDA-I para identificar los diagnósticos de enfermería en una población mediante un estudio de seguimiento médico y epidemiológico de una cohorte de 7.190 personas. Se asignó el nivel de vulnerabilidad de los participantes, entre los que también se asignaron diagnósticos de enfermería, utilizando el "índice REI" para calcular las asociaciones esperadas. RESULTADOS: El diagnóstico de enfermería más prevalente en nuestra muestra fue Estilo de vida sedentario (60,5%), seguido de Autogestión ineficaz de la salud (33,8%) y Tendencia a adoptar conductas de riesgo para la salud (28,7%). Se encontraron diferencias significativas por sexo, grupo de edad y clase social, siendo los diagnósticos de enfermería incluidos en el estudio más prevalentes entre la clase social más desfavorecida socioeconómicamente. CONCLUSIONES: El método de mapeo cruzado es útil para generar información diagnóstica en términos de necesidades de cuidados, utilizando la clasificación NANDA-I. Se han verificado las asociaciones esperadas entre alta vulnerabilidad social y necesidades de cuidados en una muestra amplia y representativa de la población canaria (España). IMPLICACIONES PARA LA PRÁCTICA ENFERMERA: Desde una perspectiva epidemiológica, la identificación de los diagnósticos de enfermería a nivel poblacional permite encontrar las necesidades más prevalentes en los diferentes grupos de la comunidad y focalizar las intervenciones enfermeras adecuadas para su implementación y evaluación de impacto.

Developing CIRdb as a catalog of natural genetic variation in the Canary Islanders.

The current inhabitants of the Canary Islands have a unique genetic makeup in the European diversity landscape due to the existence of African footprints from recent admixture events, especially of North African components (> 20%). The underrepresentation of non-Europeans in genetic studies and the sizable North African ancestry, which is nearly absent from all existing catalogs of worldwide genetic diversity, justify the need to develop CIRdb, a population-specific reference catalog of natural genetic variation in the Canary Islanders. Based on array genotyping of the selected unrelated donors and comparisons against available datasets from European, sub-Saharan, and North African populations, we illustrate the intermediate genetic differentiation of Canary Islanders between Europeans and North Africans and the existence of within-population differences that are likely driven by genetic isolation. Here we describe the overall design and the methods that are being implemented to further develop CIRdb. This resource will help to strengthen the implementation of Precision Medicine in this population by contributing to increase the diversity in genetic studies. Among others, this will translate into improved ability to fine map disease genes and simplify the identification of causal variants and estimate the prevalence of unattended Mendelian diseases.

Incidence and mortality of cerebrovascular disease in Spain: 1,600,000 hospital admissions between 2001 and 2015.

BACKGROUND: To analyze the incidence and mortality of cerebrovascular diseases (CeVD) in Spain from 2001 to 2015. METHODS: Retrospective study of hospital incidence, hospital case fatality and population mortality, with records from the Spanish Government Statistics. Days of hospital stay and risk of death (RD) during admission were estimated adjusting for age, sex, first stroke (FS), atrial fibrillation (AF), diabetes, hypertension, and smoking. RESULTS: There were 1,662,487 stroke cases older than 15 years of age admitted to hospital (1,096,748 FS), with a national incidence = 291/105 in this period (Murcia maximum (367/105), Canary Islands minimum (238/105)). Population mortality (-50%) decreased while case fatality remained stable (-3%), despite the increase in the age of patients (+2.29 years) and the incidence (+25%). Canary Islands had the youngest patients (-3.5 years for men and -6 years for women) and the longest hospital stay (+5.1 days). Andalusia (odds ratio (OR) = 1.21 (1.19; 1.22)) and the Canaries (OR = 1.18 (1.15; 1.21)) had the highest RD. The factors associated to the highest increases in RD were FS (OR = 1.34 (95% confidence interval (CI) = 1.33-1.35)) and AF (OR = 1.30 (95% CI = 1.29-1.31)). CONCLUSION: Population mortality due to CeVD was reduced by half in Spain between 2001 and 2015, but hospital incidence increased. Andalusia and the Canary Islands had the highest RD in the country. These islands presented the lowest incidence, but their patients were younger, and their hospital stay longer. FS and AF were the factors associated with a higher RD.

Mal control de la diabetes tipo 2 en un centro de salud de atención primaria: factores modificables y población diana / Uncontrolled type 2 diabetes in primary care health center: Modifiable factors and target population

Objetivos: Detectar factores modificables y poblaciones diana asociados al mal control de la diabetes tipo 2 (DM2) en atención primaria. Diseño: Estudio descriptivo transversal restrospectivo. Emplazamiento: Centro de salud de Barranco Grande, Tenerife. Participantes: selección aleatoria de pacientes con DM2 atendidos por 12 médicos de familia y 12 enfermeras. Mediciones principales: Además del control de la DM2, se obtuvieron datos sociodemográficos, clínicos, hábitos de vida y seguimiento de medidas preventivas y terapéuticas. Tras análisis bivariado, se ajustó un modelo multivariado multinivel tomando el cupo médico-enfermero como efecto mixto de segundo nivel y el resto como variables de primer nivel. Resultados: Fueron reclutados 587 pacientes (46,5% mujeres), tratados con 1,9±1,1 fármacos antidiabéticos, con 4,1% de incumplimiento terapéutico, y padeciendo un 13,8% inercia terapéutica. El 23,7% mostraba mal control de DM2, siendo peor (p<0,05) en sexo masculino, edad <65 años, evolución DM2 ≥5 años, dieta inadecuada, síndrome metabólico, ratio triglicéridos/HDL≥3, complicaciones de la DM2, índice Charlson<5, visitas a enfermera<3/año, sin ECG en el último año y mayor número de fármacos prescritos para DM2. El cupo médico-enfermero se asoció al mal control con un coeficiente intraclase de 0,01. Conclusiones: Los hombres menores de 65 años con larga evolución de DM2 son población diana para intensificar intervenciones. El incumplimiento terapéutico, dieta inadecuada, falta de adhesión a los protocolos de seguimiento y ratio triglicéridos/HDL>3 son factores sobre los que intervenir. La asociación del cupo médico-enfermero con el control de la DM2 es débil, probablemente por adecuado seguimiento de los programas preventivos.(AU)

Aims: To detect modifiable factors and target populations associated with uncontrolled type 2 diabetes in primary care. Design: Retrospective cross-sectional descriptive study. Location: Health center of Barranco Grande, Tenerife. Participants: Random selection of patients with DM2 attended by 12 family doctors and 12 nurses. Main Measurements: In addition to the control of DM2, sociodemographic, clinical data, lifestyle and follow-up of preventive and therapeutic measures were obtained. After bivariate analysis, a multilevel multivariate model was adjusted by taking the quota of patients assisted by each physician as a second-level mixed-effect variable and the rest as first-level variables. Results: 587 patients were recruited (46.5% female), treated with 1.9-1.1 antidiabetic drugs, with 4.1% therapeutic non-compliance, and suffering 13.8% therapeutic inertia. 23.7% showed poor DM2 control, being significantly worse (p<0.05) in male sex, age <65 years, evolution DM2 -5 years, work-active, upper-middle studies, inadequate diet, metabolic syndrome, ratio TG/HDL-3, complications of DM2, Charlson index<5, nursing visits <3/year, without ECG in the last year, and more drugs prescribed for DM2. The doctor-nurse quota was associated with poor control with an intraclass coefficient of 0.01. Conclusions: Men under 65 years of age with DM2 evolution longer than 5 years are a target population to intensify interventions. Therapeutic non-compliance, inadequate diet, lack of adherence protocols and ratio TG/HDL>3 are the main modifiable factors on which to intervene. The association of the doctor-nurse quota with the control of DM2 is weak, probably due to adequate follow-up of preventive programs.(AU)

Evolución del tabaquismo según clase social en la población adulta de las Islas Canarias durante el periodo 2000-2015: seguimiento de la cohorte CDC-Canarias / Evolution of Smoking According to Social Class in the Adult Population of the Canary Islands During 2000-2015: Follow-up of the CDC-Canary Cohort

OBJETIVO: Conocer la evolución del consumo de tabaco en Canarias durante 2000-2015 según clase social. Emplazamiento: Comunidad Autónoma de Canarias. PARTICIPANTES: Cohorte CDC-Canarias con cortes en 2000 (n = 6.729), 2008 (n = 6.171) y 2015 (n = 4.705). Mediciones principales: Tabaquismo, sexo, edad y clase social. RESULTADOS: El consumo disminuyó un 6% (5-7%, p < 0,001) en general, siendo más acentuado en el periodo 2000-2008 (5%). La disminución fue mayor en hombres, aunque siguieron fumando más que las mujeres, con una prevalencia del 25% (24-26%) frente al 18% (17-19%, p < 0,001). Solo hubo una disminución del consumo en los grupos jóvenes (6% [3-5%]; p = 0,011) y de edades intermedias (7% [6-8%]; p < 0,001). En todas las clases sociales se observó una disminución similar, con mayor prevalencia de tabaquismo en la clase alta: 24% (23-25%) en 2015 (p < 0,001). Al valorar conjuntamente sexo, edad y clase social, los hombres más jóvenes y de edad intermedia presentaron los mayores descensos de consumo: 8% (7-9%) clase baja y alta, 10% (9-11%) clase media. En la clase social baja, las mujeres más jóvenes continúan fumando más (27%) aunque abandonaron más el consumo (14%), fenómeno que en las de clase media se produjo en edades intermedias. CONCLUSIONES: La evolución del consumo de tabaco en Canarias sigue un patrón similar al conjunto de España. El abandono del consumo de tabaco se ha frenado en el periodo 2008-2015, especialmente en hombres y en clases sociales medias y altas

OBJECTIVE: To determine the status of tobacco consumption in the Canary Islands during 2000-2015, according to social class. LOCATION: Canary Islands. PARTICIPANTS: General population cohort, with contacts in 2000 (n = 6,729), 2008 (n = 6,171) and 2015 (n = 4,705). MAIN MEASUREMENTS: Smoking, gender, age, and social class. RESULTS: Consumption decreased by 6% (5-7%, P < .001) in general, being more accentuated in the period 2000-2008 (5%). The decrease was greater in men, although they continued to smoke more than women, with a prevalence of 25% (24-26%) compared to 18% (17-19%, P < .001). A decrease in consumption was only observed in the younger groups (6% [3-5%], P = .011) and intermediate ages (7% [6-8%], P < .001). A similar decrease was observed in all the social classes, but there was a higher prevalence of smoking in the upper class: 24% (23-25%) in 2015 (P < .001). By jointly assessing gender, age, and social class, younger and middle age men had the greatest decreases in consumption: 8% (7-9%) low and upper classes, 10% (9-11%) middle class. In the lower social class, younger women continue to smoke more (27%) although more of them quit smoking (14%), a phenomenon that occurred in the middle class at intermediate ages. CONCLUSIONS: The evolution of tobacco consumption in the Canary Islands follows a pattern similar to that of mainland Spain. The abandonment of tobacco consumption has slowed down in the period 2008-2015, especially in men, and middle and upper social classes

Major amputations in type 2 diabetes between 2001 and 2015 in Spain: regional differences.

BACKGROUND: To analyze the trend of lower extremity major amputations (MA) among patients with type 2 diabetes mellitus (T2DM) in the Regions of Spain from year 2001 until 2015. METHODS: Descriptive study of 40,392 MA. Data were obtained from the national hospital discharge database in patients with T2DM. The incidence rate was calculated in each Region, in addition to the incidence ratios (IR) between annual incidence and incidence of the year 2001. The length of hospital stay and mortality risks were analyzed using regression models adjusted for sex, age and smoking. RESULTS: The major amputations incidence rate per 100,000 person-years was 0.48 in Spain; Canary Islands showed the highest incidence (0.81). The trend was a slight decrease or stability of the incidence in all Regions except in the Canary Islands (IR2015 = 2.0 [CI95% = 1.5, 2.6]) and in Madrid (IR2015 = 0.1 [CI95% = 0.1, 0.2]). Mortality after major amputations was 10% in Spain; Cantabria suffered the highest risk of death [1.7 (CI95% = 1.4; 2.1), p < 0.001] and La Rioja the lowest risk (0.5 [CI95% = 0.2; 0.9]; p = 0.026). The longest hospital stay was registered in the Canary Islands [(CI95% = 11.4;13.3], p < 0.001)], and the shortest in the Valencian Community [(CI95% = - 7.3; - 5.8), p < 0.001)]. CONCLUSION: MA in T2DM followed a growing trend in the Canary Islands, which diverged from the downward trend in Spain. The variability of mortality and hospital stay, suggest to review the clinical management in some Regions. Sudden incidence decrease in Madrid suggests checking the record procedures of hospital discharges.

Domain and intensity of physical activity are associated with metabolic syndrome: A population-based study.

INTRODUCTION: Little is known on how the domain and intensity of physical activity (PA) associates with metabolic syndrome (MetS). The aim of this study was to examine associations between PA domains (leisure-time, domestic, active transport, total walking and total PA), PA intensities (light, moderate and vigorous) and PA levels with MetS in the general adult population. METHODS: Cross-sectional study. Anthropometry, blood biochemistry, 79-item PA-questionnaire, lifestyle and medical history were evaluated in a representative sample of Canary Island adults (n = 6,729). MetS was diagnosed using the harmonized IDF-NHLBI-AHA criteria. T-test and multivariable logistic regression was used to analyse associations between PA domains and intensities with MetS vs. no MetS, controlling for socio-demographic, lifestyle, family antecedents and body mass index (BMI). RESULTS: For each MET-h/day spent in moderate-vigorous PA intensities, as well as in recreational domain, active transport, total walking and total PA, the odds of MetS decreased between 3-10%. Energy expenditure exclusively in light and domestic PAs was not associated with MetS, however it was important to achieve a total PA level of 3 MET-h/day, which reduced the odds of MetS by 23%. This reduction was blunted in those with more than 2 h/d of TV watching time. A PA level of 3 MET-h/d also nullified the risk of MetS in those with low PA and high TV consumption. CONCLUSIONS: Some types of leisure time PAs may contribute more than others to reducing MetS. Light and domestic PA play a complementary role in enhancing energy expenditure in the general population. TV watching time above 2 h/d counteracted the MetS risk reduction associated with PA level, but PA level also reduced the risk of METs presented by those with a low level of PA and an excess TV watching time. Physical activity explains a greater amount of the variance of MetS than any other factors of lifestyle, education, sex and family history, and substantially mitigates the strong association of age and BMI with MetS.

Mortalidad hospitalaria de 415.798 pacientes con IAM: 4 años antes en Canarias que en el conjunto de España / Hospital mortality in 415 798 AMI patients: 4 years earlier in the Canary Islands than in the rest of Spain

Introducción y objetivos: Canarias tiene la mortalidad por diabetes más elevada de España. El objetivo es averiguar si existen diferencias con las restantes comunidades autónomas en la mortalidad hospitalaria por infarto agudo de miocardio (IAM), en los factores asociados con esta mortalidad y la fracción poblacional atribuible a la diabetes. Métodos: Estudio descriptivo de los ingresos hospitalarios por IAM en España desde 2007 hasta 2014, registrados en el Conjunto Mínimo Básico de Datos. Resultados: Se identificaron 415.798 IAM. Los pacientes canarios (16.317) eran más jóvenes que los del resto de España (63,93 +/- 13,56 frente a 68,25 +/- 13,94 años; p < 0,001); también el fallecimiento ocurrió 4 años antes en el archipiélago (a los 74,03 +/- 11,85 frente a los 78,38 +/- 11,10 años; p < 0,001). En esta comunidad alcanzó su prevalencia máxima el tabaquismo (el 44% de los varones y el 23% de las mujeres), que se asoció con un adelanto de 13 años en la edad al IAM. Las islas Canarias tuvieron la mayor mortalidad de pacientes tanto con diabetes (8,7%) como sin ella (7,6%), y también la mayor fracción poblacional de muerte por IAM atribuible a la diabetes (9,4; IC95%, 4,8-13,6). Tras ajustar por tipo de IAM, diabetes, dislipemia, hipertensión, tabaquismo, consumo de cocaína, insuficiencia renal, sexo y edad, Canarias presentó el mayor riesgo de mortalidad respecto a España (OR = 1,25; IC95%, 1,17-1,33; p < 0,001). Fue, además, una de las comunidades autónomas que no mejoró significativamente su riesgo demortalidad por IAM durante el periodo estudiado

Introduction and objectives: The Canary Islands has the highest mortality from diabetes in Spain. The aim of this study was to determine possible differences in mortality due to acute myocardial infarction (AMI) during hospital admission between this autonomous community and the rest of Spain, as well as the factors associated with this mortality and the population fraction attributable to diabetes. Methods: Cross-sectional study of hospital admissions for AMI in Spain from 2007 to 2014, registered in the Minimum Basic Data Set. Results: A total of 415 798 AMI were identified. Canary Island patients (16 317) were younger than those living in the rest of Spain (63.93 +/- 13.56 vs 68.25 +/- 13.94; P < .001) and death occurred 4 years earlier in the archipelago (74.03 +/- 11.85 vs 78.38 +/- 11.10; P < .001). This autonomous community had the highest prevalence of smoking (44% in men and 23% in women); throughout Spain, AMI occurred 13 years earlier in smokers than in nonsmokers. Patients in the Canary Islands had the highest mortality rates whether they had diabetes (8.7%) or not (7.6%), and they also showed the highest fraction of AMI mortality attributable to diabetes (9.4; 95% CI, 4.8-13.6). After adjustment for type of AMI, diabetes, dyslipidemia, hypertension, smoking, cocaine use, renal failure, sex and age, the Canary Islands showed the highest risk of mortality vs the rest of Spain (OR = 1.25; 95%CI, 1.17-1.33; P < .001) and it was one of the autonomous communities showing no significant improvement in the risk of mortality due to AMI during the study period. Conclusions: Mortality due to AMI during hospital admission is higher in the Canary Islands than in the rest of Spain

CONCLUSIONS: Mortality due to AMI during hospital admission is higher in the Canary Islands than in the rest of Spain.

Genomic Analyses of Human European Diversity at the Southwestern Edge: Isolation, African Influence and Disease Associations in the Canary Islands.

Despite the genetic resemblance of Canary Islanders to other southern European populations, their geographical isolation and the historical admixture of aborigines (from North Africa) with sub-Saharan Africans and Europeans have shaped a distinctive genetic makeup that likely affects disease susceptibility and health disparities. Based on single nucleotide polymorphism array data and whole genome sequencing (30×), we inferred that the last African admixture took place ∼14 generations ago and estimated that up to 34% of the Canary Islander genome is of recent African descent. The length of regions in homozygosis and the ancestry-related mosaic organization of the Canary Islander genome support the view that isolation has been strongest on the two smallest islands. Furthermore, several genomic regions showed significant and large deviations in African or European ancestry and were significantly enriched in genes involved in prevalent diseases in this community, such as diabetes, asthma, and allergy. The most prominent of these regions were located near LCT and the HLA, two well-known targets of selection, at which 40‒50% of the Canarian genome is of recent African descent according to our estimates. Putative selective signals were also identified in these regions near the SLC6A11-SLC6A1, KCNMB2, and PCDH20-PCDH9 genes. Taken together, our findings provide solid evidence of a significant recent African admixture, population isolation, and adaptation in this part of Europe, with the favoring of African alleles in some chromosome regions. These findings may have medical implications for populations of recent African ancestry.

Validation of DIABSCORE in screening for Type 2 Diabetes and prediabetes in Tunisian population.

AIMS: To perform a validation of DIABSCORE in a sample of Tunisian adults and find out the optimal cut-off point for screening of Type 2 diabetes (T2D) and prediabetes. METHODS: 225 adults 18-75 years and a subgroup of 138 adults (18-54 years), with undiagnosed T2D from the region of Cap-Bon, Tunisia were included in the present study. The DIABSCORE was calculated based on: age, waist/height ratio, family history of T2D and gestational diabetes. Receiver operating characteristics (ROC) curves and areas under curve (AUC) were obtained. The T2D and prediabetes prevalences odds ratios (OR) between patients exposed and not exposed to DIABSCORE≥90 and DIABSCORE≥80, respectively were calculated in both age ranges. RESULTS: For screening of T2D the best value was DIABSCORE = 90 with a highest sensitivity (Se), negative predictive value (NPV) and lower negative likelihood ratio in participants aged 18-75 yr (Se = 97%; NPV = 97%) when compared to participants aged 18-54 yr (Se = 95%; NPV = 97%); for prediabetes, the best Se and NPV were for DIABSCORE = 80 in both age groups, but it showed a disbalanced sensitivity-specificity. The ROC curves for T2D showed a similar AUC in both age ranges (AUC = 0.62 and AUC = 0.61 respectively). The ROC curves for prediabetes showed a highest AUC in those aged 18-54 years than the older ones (AUC = 0.62 and AUC = 0.57, respectively). The prevalences OR of T2D for DIABSCORE≥90 was higher than for DIABSCORE≥80 in both age ranges. Nevertheless, the prevalences OR of prediabetes for DIABSCORE≥90 was half of the detected for DIABSCORE≥80 in both age ranges. CONCLUSION: The DIABSCORE is a simple clinical tool and accurate method in screening for T2D and prediabetes in the adult Tunisian population.

Austerity Policies and Mortality in Spain After the Financial Crisis of 2008.

OBJECTIVES: To analyze mortality in Spain and the United States before and after these countries implemented divergent policies in response to the financial crisis of 2008. METHODS: We examined mortality statistics in both countries in the years 2000 to 2015. Spain started austerity policies in 2010. We compared differences in mortality ratios, on the basis of trends and effect size analysis. RESULTS: During 2000 to 2010, overall mortality rates (r = 0.98; P < .001; Cohen's d = -0.228) decreased in both countries. In 2011, this trend changed abruptly in Spain, where observed mortality surpassed expected mortality by 29% in 2011 and by 41% in 2015. By contrast, observed mortality surpassed expected mortality in the United States by only 8% in 2015. As the mortality statistics diverged, the effect size greatly increased (d = 7.531). During this 5-year period, there were 505 559 more deaths in Spain than the expected number, while in the United States the difference was 431 501 more deaths despite the 7-fold larger population in the United States compared with Spain. CONCLUSIONS: The marked excess mortality in 2011 to 2015 in Spain is attributable to austerity policies.

Inverse association of resistin with physical activity in the general population.

AIM: Resistin is a cytokine related with inflammation and ischemic heart disease. Physical activity (PA) prevents chronic inflammation and ischemic heart disease. We studied the relationship of serum concentration of resistin with HDL cholesterol, a known biomarker of PA, and with different measures of PA, in a large sample of the general adult population in the Canary Islands. METHODS: Cross-sectional study of 6636 adults recruited randomly. We analyzed the correlation of resistin and HDL cholesterol with PA (as metabolic equivalent level [MET]), and fitted the results with linear and logistic regression models using adjustment for age, alcohol consumption and smoking. RESULTS: Mean resistin level was higher in women (p<0.001), correlated inversely with age, HDL cholesterol (p<0.001) and alcohol consumption (p<0.001 in men), and correlated directly with smoking (p<0.001). Resistin correlated inversely with the duration of leisure time PA (p<0.001), leisure time MET (p<0.001) and moderate leisure time PA (p<0.001), with some differences between sexes. Men (OR = 0.78 [0.61-0.99; p<0.05]) and women (OR = 0.75 [0.61-0.92; p<0.01]) in the upper quintile of leisure time PA had a lower risk of elevated resistin. In contrast, a high degree of sedentarism was associated with an increased risk elevated resistin in women (OR = 1.24 [1.04-1.47; p<0.05] and in men (OR = 1.40 [1.01-1.82; p<0.05]). CONCLUSIONS: In our sample of the general population, resistin was inversely associated with measures and levels of PA and HDL cholesterol. The association of resistin with PA was stronger than the association of HDL cholesterol with PA, making resistin a potentially useful biomarker of PA.
