2020
[Objective] To describe the characteristics of patients with very-late-onset myasthenia gravis (MG).
[Saccharin test for the study of mucociliary clearance: reference values for a Spanish population].
2008
Objective Mucociliary transport is an important defense mechanism for the airways. The aim of this study was to establish reference values for nasal mucociliary clearance time (MCT) by means of the saccharin test. Subjects and Methods A cross-sectional, descriptive, observational study was performed. The variables studied were nasal MCT, age, and sex. We included 249 healthy nonsmokers (134 male and 115 female subjects) aged over 10 years and stratified the sample by age. To establish reference values, percentiles were calculated and lower and upper limits of normal were established at the 2.5 and 97.5 percentiles, respectively. The association between nasal MCT and the main study variables…
Clinical and microbiological findings in patients with peri-implantitis: a cross-sectional study
2015
Objective The aim of this study was to analyze clinical and microbiological characters in subjects and implants affected and not affected by peri-implantitis. Additionally, same features were analyzed also intra-individually, comparing healthy and diseased implants within the same subject. Materials and methods A total of 534 patients who received at least 1 implant and coming to routine check-up or spontaneous visits at the University of Valencia were recruited. Clinical parameters including Bleeding on probing (BoP), Probing pocket depth (PPD), and Pi were screened. Samples for microbiological analysis were obtained from three locations: peri-implant sulci (PIS), inner parts of the implan…
Association Between Clinical and Microbiologic Cluster Profiles and Peri-implantitis
2017
Purpose: The correlation between associated local factors and peri-implantitis remains unknown. The aim of this study was to investigate the association between the clinical and microbiologic profiles and periimplantitis to eventually categorize different groups of this disease. Materials and Methods: Subjects with at least one implant presenting signs of peri-implantitis were selected. The clinical, radiographic, occlusal, and microbiologic profiles of these infected implants were collected. Cases were classified into five peri-implantitis groups according to potential disease-triggering factors: surgically, prosthetically, biomechanically, purely plaque-associated, and a combination of th…
Objective vs Subjective Vault Measurement After Myopic Implantable Collamer Lens Implantation
2009
PURPOSE: To evaluate the relationship between subjective measurements of vault and objective values measured with Visante optical coherence tomography (OCT) in eyes receiving an implantable contact lens (ICL) for myopia correction. DESIGN: Observational cross-sectional study. METHODS: SETTING: Fernández-Vega Ophthalmological Institute, Oviedo, Spain. PATIENTS: Four hundred and fifty-two eyes from 246 patients were elected to be implanted with a Visian ICL V4 (STAAR Surgical Inc, Monrovia, California, USA). OBSERVATION PROCEDURES: Subjective and objective measurements of vault after implantation of ICL. MAIN OUTCOME MEASURES: Subjective vault classified in 5 levels assessed using an optical …
Similar relative decline in aerobic and anaerobic power with age with in elite endurance and power master athletes of both sexes
2019
Lower physical activity levels in old age are thought to contribute to the age-related decline in peak aerobic and anaerobic power. Master athletes maintain high levels of physical activity with advancing age and endurance or power training may influence the extent to which these physical functions decline with advancing age. To investigate, 37-90-year-old power (n=20, 45% female) and endurance (n=19, 58% female) master athletes were recruited. Maximal aerobic power was assessed when cycling two-legged (VO2 Peak2-leg ) and cycling one-legged (VO2 Peak1-leg ), while peak jumping (anaerobic) power was assessed by a countermovement jump. Men and women had a similar VO2 Peak2-leg (mL·kg-1 ·min-…
Associations of Aerobic Fitness and Maximal Muscular Strength With Metabolites in Young Men
2019
This cross-sectional study of young Finnish men examines the associations of aerobic fitness and muscular strength with metabolome measures that are associated with cardiometabolic risks.
High psychosocial burden in relatives of malignant brain tumor patients
2018
Not only tumor patients suffer enormously from their disease, also the caregivers are massively affected by the disease of their relatives. In this study, we investigate the psychological burden in caregivers of outpatient malignant brain tumor patients.Fifty caregivers of patients with primary malignant brain tumors were included in our study. Study participants filled in a form with demographic details, a self-established questionnaire concerning general well-being and three established psychological questionnaires to assess anxiety, depression, stress and social support: The "Hospital Anxiety and Depression Scale" (HADS), the "Perceived Stress Scale" (PSS-10) and the "Social Support Ques…
Perception of the professional nursing environment in Primary Care in the Valencian Community, in departments with public and private management
2019
Resumen Fundamento Los entornos para la práctica profesional enfermera (EPE) mejoran la calidad del cuidado, la satisfacción y los resultados en salud, no existiendo ninguna medición en Atención Primaria (AP) según su modelo de gestión. Pretendemos estimar y comparar la percepción de la calidad de dichos ERE en AP en tres departamentos de salud (DS) de la Comunidad Valenciana con modelos de gestión pública y privada (concesión administrativa). Material y métodos Estudio transversal en profesionales de Enfermería de AP de tres DS, uno de gestión pública y dos de gestión privada. Se utilizó el cuestionario Practice Environment Scale-Nursing Work Index validado en España y se recogieron variab…
Proteomics of Orbital Tissue in Thyroid-Associated Orbitopathy.
2015
A potentially altered protein expression profile in orbital tissue from patients with thyroid-associated orbitopathy (TAO) is suspected.To detect for the first time changes in proteomic patterns of orbital connective tissue in TAO and compare these with control tissue using mass spectrometry.Proteomics cross-sectional, comparative study.Two academic endocrine institutions.A total of 64 orbital and peripheral adipose tissue samples were collected from 39 patients with TAO and 25 control subjects.Samples were analyzed and identified using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry technology.Mean intensity values of all identified peptides per protein.Thirty-…
