Plasma homocysteine in adolescents depends on the interaction between methylenetetrahydrofolate reductase genotype, lipids and folate: a seroepidemiological study

<p>Abstract</p> <p>Background</p> <p>Many publications link high homocysteine levels to cardiovascular disease. In Spain there is little information on the prevalence of hyperhomocysteinaemia and associated vitamin factors among the general population, and less still among children. Cardiovascular risk factors in the childhood population may be related to the appearance of cardiovascular disease at adult age. The aim of this study is to establish a definition of hyperhomocysteinaemia in adolescents and to analyze the influence of vitamin and metabolic factors in homocysteine levels in this population group.</p> <p>Methods</p> <p>Descriptive, cross-sectional epidemiological study to estimate serum homocysteine, vitamin B12 and folate levels, as well as plasma total, HDL- and LDL- cholesterol in a schoolgoing population aged 13 to 17 years in Madrid, Spain.</p> <p>Spearman correlation analysis was performed to ascertain quantitative comparison, Pearson's χ2 test (frequency < 5, Fisher) was used for comparison of prevalences, Mann-Whitney U and Kruskal-Wallis test were used for comparison of means and Bonferroni correction was used for post-hoc tests. A multivariate logistic regression model was performed in the multivariate analysis.</p> <p>Results</p> <p>Based on the classic values for definition of hyperhomocysteinaemia in adults, prevalence of hyperhomocysteinaemia in the study population was: 1.26% for 15 μmol/L; and 2.52% for 12 μmol/L.</p> <p>Deficits in HDL cholesterol and serum folate levels yielded adjusted Odds Ratios (OR) for hyperhomocysteinemia of 2.786, 95% CI (1.089-7.126), and 5.140, 95% CI (2.347-11.256) respectively. Mutation of the methylenetetrahydrofolate reductase (MTHFR) C677T genotype also raises the risk of hyperhomocysteinaemia (CC→CT: OR = 2.362; 95% CI (1.107-5.042) CC→TT: OR = 6.124, 95% CI (2.301-16.303))</p> <p>Conclusion</p> <p>A good definition of hyperhomocysteinaemia in adolescents is the 90^thpercentile, equivalent to 8.23 μmol/L. Risk factors for hyperhomocysteinaemia are cHDL and folate deficiency, and the MTHFR C677T mutant genotype. No significant effect could be assessed for vitamin B₁₂. Coexistence of all three factors increases the risk of suffering from hyperhomocysteinaemia 87-fold.</p

Measuring the Burden of Hospitalization in Patients with Parkinson´s Disease in Spain

Introduction: This epidemiological survey estimates the hospitalization burden related to Parkinson´s Disease in Spain. Methods: This observational retrospective survey was performed by reviewing data from the National Surveillance System for Hospital Data, which includes more than 98% of Spanish hospitals. All hospitalizations of patients with Parkinson´s disease that were reported from 1997-2012 were analyzed. Codes were selected using the 9th International Classification of Diseases: ICD-9-CM: 332.0. Results: A total of 438,513 hospital discharges of patients with Parkinson´s Disease were reported during the study period. The annual hospitalization rate was 64.2 cases per 100,000. The average length of hospital stay was 10 days. The trend for the annual hospitalization rate differed significantly depending on whether Parkinson´s disease was the main cause of hospitalization (n = 23,086, 1.14% annual increase) or was not the main cause of hospitalization (n = 415,427, 15.37% annual increase). The overall case-fatality rate among hospitalized patients was 10%. The case fatality rate among patient´s hospitalized with Parkinson´s disease as the main cause of hospitalization was 2.5%. The hospitalization rate and case-fatality rate significantly increased with age. The primary causes of hospitalization when Parkinson´s disease was not coded as the main cause of hospitalization were as follows: respiratory system diseases (24%), circulatory system diseases (19%), injuries and poisoning, including fractures (12%), diseases of the digestive system (10%) and neoplasms (5%). The annual average cost for National Health Care System was € 120 M, with a mean hospitalization cost of €4,378. Conclusions: Parkinson´s disease poses a significant health threat in Spain, particularly in the elderly. While hospitalizations due to Parkinson´s Disease are relatively stable over time, the number of patients presenting with Parkinson´s disease as an important comorbidity has increased dramatically. Medical staff must be specifically trained to treat the particular needs of hospitalized patients suffering from Parkinson´s disease as an important comorbidity.Funding sources for study: The cathedra “Evaluación de Resultados en Salud.

Intussusception following rotavirus vaccination in the Valencia Region, Spain

Studies have shown high intussusception rates in Spain. We performed a hospital-based retrospective observational study of the intussusception risk following rotavirus vaccinations among infants in Valencia, a region of Spain with an annual birth cohort of approximately 48,000 children, during 2007–2011, using a self-controlled case series design. We performed medical record review of all cases using Brighton Collaboration´s case definition and assessed the positive predictive value (PPV) of the intussusception diagnosis code. Among 151 hospitalized cases discharged as intussusception, we confirmed 136 as Brighton Collaboration's Levels 1 or 2, resulting in a PPV of 93% (95% CI: 87%–96%). Three confirmed cases occurred within days 1–7 following the first rotavirus vaccination. The incidence rate ratio was 9.0 (95% CI: 0.9–86.5) (crude) and 4.7 (95% CI:0.3–74.1)(age adjusted). In this first study in Europe, the intussusception risk point estimate was comparable to other studies, although results were not statistically significant, maybe due to limited power. The high PPV found will facilitate implementation of a larger study without requiring medical record review. Our finding of very few vaccinated cases despite a thorough 5-year investigation in a country that, according to previous studies, may have a large background rate of intussusception is reassuring and should contribute to deliberations about the need to include rotavirus vaccines in the official Spanish calendars

Coordinación y colaboración interdisciplinar entre profesorado y asignaturas para mejorar la calidad de la docencia universitaria

Innovación EducativaLa Universidad necesita nuevas formas de organización docente y establecer lazos con instituciones externas dedicadas a la práctica laboral para proporcionar a nuestro alumnado aprendizajes interdisciplinares y competenciales que les permitan una formación de calidad para el desempeño de su futura vida laboral. En este Proyecto de Innovación Docente (PID) hemos realizado una primera aproximación al conocimiento de las diferentes formas de coordinación y colaboración docente a través de la revisión bibliográfica y posteriormente hemos analizado el nivel de coordinación y colaboración de una muestra de docentes (n=18) de nuestra Universidad mediante la realización de una encuesta. En el marco de este PID se han establecido nuevos vínculos de coordinación y colaboración tanto entre profesores y asignaturas como con instituciones externas a la Universidad. Finalmente se ha llevado a cabo un análisis del impacto de la implementación de nuevas formas de coordinación y colaboración interdisciplinar, tanto desde el punto de vista del profesorado como del alumnado.Departamento de Psicologí

Una enfermedad lejana: la información sobre poliomielitis y síndrome post-polio en la prensa hispanolusa, 1995-2009

Se explora el cambio en la percepción social de la polio en la Península Ibérica a través del análisis de contenidos, entre 1995 y 2009, de dos periódicos de gran tirada. La desaparición en la agenda periodística de la polio y de las personas que viven con sus secuelas influyó en el olvido de la misma en la agenda pública. La poliomielitis se vinculó a la pobreza y la ignorancia en países lejanos, susceptibles de acciones de cooperación, siendo objeto de atención solo cuando es percibida como amenaza para Occidente, vinculada a crisis sanitarias o en un sentido metafórico. Así, el síndrome post-polio fue invisibilizado en el caso portugués y débilmente representado en España por el movimiento asociativo

Design and baseline characteristics of the finerenone in reducing cardiovascular mortality and morbidity in diabetic kidney disease trial

Background: Among people with diabetes, those with kidney disease have exceptionally high rates of cardiovascular (CV) morbidity and mortality and progression of their underlying kidney disease. Finerenone is a novel, nonsteroidal, selective mineralocorticoid receptor antagonist that has shown to reduce albuminuria in type 2 diabetes (T2D) patients with chronic kidney disease (CKD) while revealing only a low risk of hyperkalemia. However, the effect of finerenone on CV and renal outcomes has not yet been investigated in long-term trials. Patients and Methods: The Finerenone in Reducing CV Mortality and Morbidity in Diabetic Kidney Disease (FIGARO-DKD) trial aims to assess the efficacy and safety of finerenone compared to placebo at reducing clinically important CV and renal outcomes in T2D patients with CKD. FIGARO-DKD is a randomized, double-blind, placebo-controlled, parallel-group, event-driven trial running in 47 countries with an expected duration of approximately 6 years. FIGARO-DKD randomized 7,437 patients with an estimated glomerular filtration rate >= 25 mL/min/1.73 m(2) and albuminuria (urinary albumin-to-creatinine ratio >= 30 to <= 5,000 mg/g). The study has at least 90% power to detect a 20% reduction in the risk of the primary outcome (overall two-sided significance level alpha = 0.05), the composite of time to first occurrence of CV death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure. Conclusions: FIGARO-DKD will determine whether an optimally treated cohort of T2D patients with CKD at high risk of CV and renal events will experience cardiorenal benefits with the addition of finerenone to their treatment regimen.

Hospitalizations associated with malignant neoplasia and in situ carcinoma in the anus and penis in men and women during a 5-year period (2009–2013) in Spain: An epidemiological study

Background Approximately 40,000 new cases of anal cancer and 26,000 new cases of penile cancer occurred in 2012 worldwide. Human Papillomavirus (HPV) infection is responsible for 88.3% and 33.0% of these cancers, respectively. The aim of this study was to describe the hospital burden associated with malignant neoplasm (MN) and in situ carcinoma (ISC) in the anus and penis in Spain from 2009 to 2013. Methods This observational, retrospective study used discharge information obtained from the national surveillance system for hospital data, Conjunto Mínimo Básico de Datos, provided by the Ministry of Health. Results We found 3,668 hospitalizations due to MN and ISC in the anus for both genders, and more than 55% of these hospitalizations occurred in men and were associated with a lower median age of hospitalization (p 14 y old and 1.604 per 100,000 women aged > 14 y old, p 14 y old. The hospitalization rate due to MN and ISC in the anus in males increased significantly during this period (p = 0.048). Conclusion Our study provides relevant information about the hospital burden of anal and penile MN and ISC in Spain. This information could be useful for cost effectiveness analysis of universal HPV vaccination and for future HPV vaccination impact monitoring in Spain, and for other countries of similar socioeconomic status
