PREVALENCE OF UNKNOWN DIABETES AND IMPAIRED GLUCOSE TOLERANCE IN PATIENTS WITH IMPAIRED FASTING GLUCOSE

There are many community-based studies on the prevalence of diabetes, impaired glucose tolerance (IGT) and impaired fasting glucose (IFG). However, studies on the prevalence of IGT and diabetes unknown in patients with IFG, by 75-g oral glucose tolerance test (OGTT), are few and small.CIBEROBN is an Instituto de Salud Carlos III initiative.

Development of a SNP parentage assignment panel in some North-Eastern Spanish meat sheep breeds

Aim of study: To validate two existing single nucleotide polymorphism (SNP) panels for parentage assignment in sheep, and develop a cost effective genotyping system to use in some North-Eastern Spanish meat sheep populations for accurate pedigree assignment.Area of study: SpainMaterial and methods: Nine sheep breeds were sampled: Rasa Aragonesa (n=38), Navarra (n=39), Ansotana (n=41), Xisqueta (n=41), Churra Tensina (n=38), Maellana (39), Roya Bilbilitana (n=24), Ojinegra (n=36) and Cartera (n=39), and these animals were genotyped with the Illumina OvineSNP50 BeadChip array. Genotypes were extracted from the sets of 249 SNPs and 163 SNPs for parentage assignment designed in France and North America, respectively. Validation of a selected cost-effective genotyping panel of 158 SNPs from the French panel were performed by Kompetitive allele specific PCR (KASP). Additionally, some functional SNPs (n=15) were also genotyped.Main results: The set of 249 SNPs for parentage assignment showed better diversity, probability of identity, and exclusion probabilities than the set of 163 SNPs. The average minor allele frequency for the set of 249, 163 and 158 SNPs were 0.41 + 0.01, 0.39 + 0.01 and 0.42 + 0.01, respectively. The parentage assignment rate was highly dependent to the percentage of putative sires genotyped.Research highlights: The described method is a cost-effective genotyping system combining the genotyping of SNPs for the parentage assignment with some functional SNPs, which was successfully used in some Spanish meat sheep breeds

Studying sporadic and familial Alzheimer's disease on iPSC-derived hippocampal and cortical neurons: effect of APOE and Presenilin1

Alzheimer's disease (AD) is pathologically characterised by the presence of amyloid-beta plaques, neurofibrillary tangles containing hyperphosphorylated Tau protein, neuroinflammation and neuronal death leading to progressive cognitive impairment. The ¿4 allele of the gene encoding apolipoprotein E (APOE), which is mainly expressed in glial cells, is the strongest genetic risk factor for sporadic AD. Increasing evidence has shown that APOE4 may disrupt normal astrocyte activity, potentially contributing to AD pathology, but the impact of different APOE alleles on astrocyte differentiation, maturation and function is not yet fully understood. To go in depth on these questions, we obtained induced pluripotent stem cells (iPSCs) from fibroblasts of AD patients carrying ¿3 and ¿4 alleles (in homozygosis) and from healthy patients. We also used gene-edited iPSC lines homozygous for the main APOE variants and an APOE knock-out line. iPSC-derived human astrocytes were generated by establishing a differentiation protocol through the consecutive addition of small molecules and growth factors, and the expression of typical markers (GFAP, GLT1, AQP4 and S100beta) and APOE was analysed. In addition, astrocytes exhibited functional features like glutamate uptake capacity and calcium waves production. They also responded to an inflammatory stimulus (IL-1beta and TNF-alpha) or to the presence of amyloid-beta 1-42 peptide by changing their morphology and increasing the expression levels of pro-inflammatory factors and cytokines. Our results shed light on the potential dual role of APOE polymorphism and the individual¿s genetic background in favouring or perhaps preventing AD pathology

The value of metabolic imaging to predict tumour response after chemoradiation in locally advanced rectal cancer

Preliminary data of this work were presented by RCM and awarded at the 2009 Annual Meeting of the Spanish Society of Coloproctology (AECP) held in Barcelona.Background: We aim to investigate the possibility of using 18F-positron emission tomography/computer tomography (PET-CT) to predict the histopathologic response in locally advanced rectal cancer (LARC) treated with preoperative chemoradiation (CRT). Methods: The study included 50 patients with LARC treated with preoperative CRT. All patients were evaluated by PET-CT before and after CRT, and results were compared to histopathologic response quantified by tumour regression grade (patients with TRG 1-2 being defined as responders and patients with grade 3-5 as non-responders). Furthermore, the predictive value of metabolic imaging for pathologic complete response (ypCR) was investigated. Results: Responders and non-responders showed statistically significant differences according to Mandard's criteria for maximum standardized uptake value (SUVmax) before and after CRT with a specificity of 76,6% and a positive predictive value of 66,7%. Furthermore, SUVmax values after CRT were able to differentiate patients with ypCR with a sensitivity of 63% and a specificity of 74,4% (positive predictive value 41,2% and negative predictive value 87,9%); This rather low sensitivity and specificity determined that PET-CT was only able to distinguish 7 cases of ypCR from a total of 11 patients. Conclusions: We conclude that 18-F PET-CT performed five to seven weeks after the end of CRT can visualise functional tumour response in LARC. In contrast, metabolic imaging with 18-F PET-CT is not able to predict patients with ypCR accuratelyFounded by the Fundación Investigación Mutua Madrileña. We are indebted to M.

Hyperkalemia in Heart Failure Patients in Spain and Its Impact on Guidelines and Recommendations: ESC-EORP-HFA Heart Failure Long-Term Registry

[Abstract] Introduction and objectives: Hyperkalemia is a growing concern in the treatment of patients with heart failure and reduced ejection fraction because it limits the use of effective drugs. We report estimates of the magnitude of this problem in routine clinical practice in Spain, as well as changes in potassium levels during follow-up and associated factors. Methods: This study included patients with acute (n=881) or chronic (n=3587) heart failure recruited in 28 Spanish hospitals of the European heart failure registry of the European Society of Cardiology and followed up for 1 year. Various outcomes were analyzed, including changes in serum potassium levels and their impact on treatment. Results: Hyperkalemia (K+> 5.4 mEq/L) was identified in 4.3% (95%CI, 3.7%-5.0%) and 8.2% (6.5%-10.2%) of patients with chronic and acute heart failure, respectively, and was responsible for 28.9% of all cases of contraindication to mineralocorticoid receptor antagonist use and for 10.8% of all cases of failure to reach the target dose. Serum potassium levels were not recorded in 291 (10.8%) of the 2693 chronic heart failure patients with reduced ejection fraction. During follow-up, potassium levels increased in 179 of 1431 patients (12.5%, 95%CI, 10.8%-14.3%). This increase was directly related to age, diabetes, and history of stroke and was inversely related to history of hyperkalemia. Conclusions: This study highlights the magnitude of the problem of hyperkalemia in patients with heart failure in everyday clinical practice and the need to improve monitoring of this factor in these patients due to its interference with the possibility of receiving optimal treatment.[Resumen] Introducción y objetivos. La hiperpotasemia es una preocupación creciente en el tratamiento de los pacientes con insuficiencia cardiaca y fracción de eyección reducida, pues limita el uso de fármacos eficaces. Este trabajo ofrece estimaciones de la magnitud de este problema en la práctica clínica habitual en España, los cambios en las concentraciones de potasio en el seguimiento y los factores asociados. Métodos. Pacientes con insuficiencia cardiaca aguda (n = 881) y crónica (n = 3.587) seleccionados en 28 hospitales españoles del registro europeo de insuficiencia cardiaca de la European Society of Cardiology y seguidos 1 año para diferentes desenlaces, incluidos cambios en las cifras de potasio y su impacto en el tratamiento. Resultados. La hiperpotasemia (K+ > 5,4 mEq/l) está presente en el 4,3% (IC95%, 3,7-5,0%) y el 8,2% (6,5-10,2%) de los pacientes con insuficiencia cardiaca crónica y aguda; causa el 28,9% de todos los casos en que se contraindica el uso de antagonistas del receptor de mineralocorticoides y el 10,8% de los que no alcanzan la dosis objetivo. Del total de 2.693 pacientes ambulatorios con fracción de eyección reducida, 291 (10,8%) no tenían registrada medición de potasio. Durante el seguimiento, 179 de 1.431 (12,5%, IC95%, 10,8-14,3%) aumentaron su concentración de potasio, aumento relacionado directamente con la edad, la diabetes mellitus y los antecedentes de ictus e inversamente con los antecedentes de hiperpotasemia. Conclusiones. Este trabajo destaca el problema de la hiperpotasemia en pacientes con insuficiencia cardiaca de la práctica clínica habitual y la necesidad de continuar y mejorar la vigilancia de este factor en estos pacientes por su interferencia en el tratamiento óptimo

Cardiac electrical defects in progeroid mice and Hutchinson-Gilford progeria syndrome patients with nuclear lamina alterations

Hutchinson-Gilford progeria syndrome (HGPS) is a rare genetic disease caused by defective prelamin A processing, leading to nuclear lamina alterations, severe cardiovascular pathology, and premature death. Prelamin A alterations also occur in physiological aging. It remains unknown how defective prelamin A processing affects the cardiac rhythm. We show age-dependent cardiac repolarization abnormalities in HGPS patients that are also present in the Zmpste24−/− mouse model of HGPS. Challenge of Zmpste24−/− mice with the β-adrenergic agonist isoproterenol did not trigger ventricular arrhythmia but caused bradycardia-related premature ventricular complexes and slow-rate polymorphic ventricular rhythms during recovery. Patch-clamping in Zmpste24−/− cardiomyocytes revealed prolonged calcium-transient duration and reduced sarcoplasmic reticulum calcium loading and release, consistent with the absence of isoproterenol-induced ventricular arrhythmia. Zmpste24−/− progeroid mice also developed severe fibrosis-unrelated bradycardia and PQ interval and QRS complex prolongation. These conduction defects were accompanied by overt mislocalization of the gap junction protein connexin43 (Cx43). Remarkably, Cx43 mislocalization was also evident in autopsied left ventricle tissue from HGPS patients, suggesting intercellular connectivity alterations at late stages of the disease. The similarities between HGPS patients and progeroid mice reported here strongly suggest that defective cardiac repolarization and cardiomyocyte connectivity are important abnormalities in the HGPS pathogenesis that increase the risk of arrhythmia and premature death

Cysteamine (Cystagon®) adherence in patients with cystinosis in Spain: successful in children and a challenge in adolescents and adults.

Journal Article; Research Support, Non-U.S. Gov't;BACKGROUND Cysteamine has improved survival and prognosis in cystinosis. Increasing numbers of patients reach adulthood and face new challenges such as compliance that wanes over time. The aim of this study was to evaluate adherence to cysteamine treatment in a group of cystinotic patients in Spain in an attempt to identify potential therapy pitfalls and improve the overall care of affected individuals. Despite the impact of cysteamine on prognosis, there is a paucity of data regarding adherence. METHOD Thirty-four cystinotic patients (21 male) 38% ≥18 years were enrolled in a voluntary, anonymous survey. Replies were obtained from patients (15/34), mothers (11/34), fathers (4/34) and both parents (4/34). RESULTS Patient age (median and interquartile range) at diagnosis was 1 year (0.57-1), and patient age at Cystagon® initiation was also 1 year (0.8-1.8). Sixteen (47%) were kidney transplant (KTx) recipients; six were retransplanted. Age at first KTx 10 years (8.7-13.7). Patient understanding of multiorgan involvement in cystinosis: 4.1 organs reported; eye 97% and kidney 91%. Cysteamine was given by mother (100%) and father (83%) in <11 year olds, or self-administered (94%) in ≥11 year olds. Four daily doses in 89% versus 56% in <11 year olds or ≥11 year olds, with fixed schedule in 94% versus 50% in <11 or ≥11 year olds and progressive loss of reminders over time. Furthermore, 44% complained of unpleasant smell. Motivation for treatment compliance was 100% versus 40% in <11 versus ≥11 year olds, respectively. Disease impact in patients <18 years is as follows: school (29%), social (14%), 'feeling different' (10%); in patients ≥18 years: 'feeling different' (62%), professional (39%) and job absenteeism (31%). Referring physician: paediatric nephrologist (94%) and nephrologist (63%) in <11 versus ≥11 year olds. Ophthalmological follow-up: 83% versus 38% in <11 versus ≥11 year olds. Patient opinion of physician expertise: paediatric nephrologist (94%) and nephrologist (44%). New treatment options (65%) and better information (42%) were demanded to improve adherence. CONCLUSION Treatment with Cystagon is effective in young patients. However, adherence diminishes over time in adolescents and adults despite disease impact. Strategies such as better information on the disease, patient self-care promotion and facilitated transition to adult healthcare services are required to improve compliance and the clinical management of cystinosis.This study has been supported by A.C.
