Body size at birth and age-related macular degeneration in old age
2019
Purpose To study associations between body size at birth and age-related macular degeneration (AMD) in old age. Methods The study sample consists of 1497 community-dwelling individuals (56.1% women) aged 67-89 years with birth data and retinal data collected twice in old age 5 years apart. Birth data (weight, length, birth order) were extracted from original birth records. Digital retinal photographs were graded to determine AMD status. Data on covariates were collected at the baseline physical examination in old age. Multivariable regression analyses were used to study the association between birth data and AMD adjusting for known confounding factors, including birth year cohort effects. R…
Correlación entre la expresión de microRNAs en hipertensión ocular versus glaucoma primario de ángulo abierto
2018
El Glaucoma Primario de Ángulo Abierto (GPAA), la primera causa mundial de ceguera irreversible, aumenta su prevalencia en mayores de 40 años. El primer factor de riesgo es la hipertensión ocular (HTO). No existe un biomarcador que pueda identificar sujetos con mayor predisposición hacia el GPAA. Planteamos la búsqueda de biomarcadores moleculares que ayuden a predecir el riesgo de padecer la enfermedad o de progresión de la misma. Las pequeñas moléculas de ARN no codificante (21-30 nucleótidos) que regulan la expresión génica a nivel posttranscripcional, se denominan miRNAs y se han relacionado con diversas patologías oculares. Esta Tesis Doctoral propone relacionar el perfil diferencial d…

Endocrine effects of sauna bath
2020
Sauna bath brings about numerous acute changes in hormone levels, partly akin to other stressful situations, partly specific for sauna. Norepinephrine increases in those accustomed to sauna bath. Sweating increases the production of antidiuretic hormone, and the renin-angiotensin system becomes activated. Of the anterior pituitary hormones, growth hormone (GH) and prolactin (PRL) secretion is increased. Also β-endorphin has been frequently reported to increase, whereas the responses of ACTH and cortisol are variable, probably depending on the type of sauna exposure. Sperm production decreases in particular in sauna-naïve men, but reduced fertility has not been associated with regular sauna …
Transitioning from Preclinical to Clinical Heart Failure with Preserved Ejection Fraction: A Mechanistic Approach.
2020
International audience; To better understand heart failure with preserved ejection fraction (HFpEF), we need to better characterize the transition from asymptomatic pre-HFpEF to symptomatic HFpEF. The current emphasis on left ventricular diastolic dysfunction must be redirected to microvascular inflammation and endothelial dysfunction that leads to cardiomyocyte remodeling and enhanced interstitial collagen deposition. A pre-HFpEF patient lacks signs or symptoms of heart failure (HF), has preserved left ventricular ejection fraction (LVEF) with incipient structural changes similar to HFpEF, and possesses elevated biomarkers of cardiac dysfunction. The transition from pre-HFpEF to symptomati…
Glaucomatous Maculopathy: Thickness Differences on Inner and Outer Macular Layers between Ocular Hypertension and Early Primary Open-Angle Glaucoma U…
2020
The purpose of this study was to compare the thickness of all inner and outer macular layers between ocular hypertension (OHT) and early primary open-angle glaucoma (POAG) using spectral domain optical coherence tomography (SD-OCT) 8 × 8 posterior pole algorithm (8 × 8 PPA). Fifty-seven eyes of 57 OHT individuals and fifty-seven eyes of 57 early POAG patients were included. The thickness of macular retinal nerve fiber layer (mRNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), inner nuclear layer (INL), outer plexiform and nuclear layer, photoreceptor layer (PRL) and retinal pigment epithelium were obtained in 64 cells for each macular layer and mean thickness of superior and inf…
Influencia de la variabilidad glucémica sobre la salud micro y macrovascular en niños y adolescentes con diabetes tipo 1
2015
INTRODUCCIÓN: La enfermedad cardiovascular precoz es la principal causa de morbi-mortalidad en el paciente diabético. Se ha demostrado que el estrés oxidativo, responsable del daño vascular, es mayor en condiciones de hiperglucemia intermitente que durante la hiperglucemia mantenida. La implicación de la variabilidad glucemia como causa de las complicaciones vasculares de la diabetes es controvertida y prácticamente no estudiada en la edad pediátrica. HIPÓTESIS: La variabilidad glucémica se relaciona en niños y adolescentes diabéticos tipo 1 con las complicaciones subclínicas macro y microvasculares. MATERIAL Y MÉTODOS: Estudio transversal, analítico y observacional realizado en la Unidad d…
