[Spanish asthma patients' beliefs about health and medicines: validation of 2 questionnaires].
2008
Abstract Objective We translated 2 health beliefs questionnaires–an instrument based on the health belief model (HBM) containing 19 items in 6 domains and the Beliefs About Medicines Questionnaire (BMQ) containing 18 items divided into a general and a specific section–and then administered and validated them in a group of Spanish patients with asthma. Patients and Methods In 2 clinical visits data were collected on 126 patients with stable asthma of different levels of severity. At the first visit, the patients underwent spirometry and were asked questions about sociodemographic factors and clinical history. At the second visit, they completed the State-Trait Anxiety Inventory, the Beck Dep…
Five-year functional outcomes and vault of -20 diopter myopic phakic intraocular lens implantation.
2015
Purpose To evaluate refractive and visual outcomes and complications associated with phakic intraocular lens (pIOL) implantation to correct high myopia. Settings Fernandez-Vega Ophthalmological Institute, Oviedo, Spain. Design Retrospective observational case series. Methods Uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA), refraction, vault, and adverse effects were evaluated after 5 years with Visian ICMV4 pIOL. Results Mean spherical equivalent (SE) dropped from −18.32 ± 2.37 diopters (D) preoperatively to −0.88 ± 0.52D 5 years postoperatively; 61% of eyes were within ±0.75 D of the target. The mean Snellen decimal CDVA and UDVA were 0.73 ± 0.23 and 0…
Collagen copolymer posterior chamber phakic intraocular lens supported by the ciliary sulcus to treat myopia: One-year follow-up
2014
Purpose To evaluate the predictability, stability, safety, and efficacy of Visian V4b Implantable Collamer Lens phakic intraocular lens (pIOL) implantation to treat varying degrees of myopia. Setting Fernandez-Vega Ophthalmological Institute, Oviedo, Spain. Design Prospective nonrandomized clinical study. Methods The uncorrected (UDVA) and corrected (CDVA) distance visual acuities, refraction, pIOL vault, and adverse effects were evaluated 12 months postoperatively. Results The study enrolled 121 eyes (68 patients). The mean spherical equivalent decreased from −8.61 diopters (D) ± 3.41 (SD) (range −18.75 to −2.25 D) preoperatively to −0.18 ± 0.29 D (range −1.25 to 0.50 D) 12 months postoper…
Quantifying changes in EEG complexity induced by photic stimulation.
2009
Summary Objectives: This study aims to characterize EEG complexity, measured as the prediction error resulting from nonlinear prediction, in healthy humans during photic stimulation. Methods: EEGs were recorded from 15 subjects with eyes closed (EC) and eyes open (EO), during the baseline condition and during stroboscopic photic stimulation (PS) at 5, 10, and 15 Hz. The mean squared prediction error (MSPE) resulting from nearest neighbor local linear prediction was taken as complexity index. Complexity maps were generated interpolating the MSPE index over a schematic scalp representation. Results: Statistical analysis revealed that: i) EEG shows good predictability in all conditions and see…
Categorizing the Role of Respiration in Cardiovascular and Cerebrovascular Variability Interactions
2022
Objective: Respiration disturbs cardiovascular and cerebrovascular controls but its role is not fully elucidated. Methods: Respiration can be classified as a confounder if its observation reduces the strength of the causal relationship from source to target. Respiration is a suppressor if the opposite situation holds. We prove that a confounding/suppression (C/S) test can be accomplished by evaluating the sign of net redundancy/synergy balance in the predictability framework based on multivariate autoregressive modelling. In addition, we suggest that, under the hypothesis of Gaussian processes, the C/S test can be given in the transfer entropy decomposition framework as well. Experimental p…
Resting metabolic rate and postabsorptive substrate oxidation in morbidly obese subjects before and after massive weight loss
1996
OBJECTIVE: To investigate the changes of resting metabolic rate (RMR) and postabsorptive oxidation of carbohydrates (CHO), lipids (LIP) and proteins (PT) in morbidly obese subjects after long-term stable massive weight reduction. DESIGN: Longitudinal, intervention study of a bilio-pancreatic by-pass. SUBJECTS: Ten (Four men, six women) obese subjects (BMI: 53.7 ± 2.1 kg/m2, men, nine women) control subjects (BMI: 21.4 ± 1.0 kg/m2). MEASUREMENTS: RMR and substrates oxidation (indirect calorimetry), body composition (bioelectrical impedance), plasma concentrations of glucose, FFA, insulin and thyroid hormones before (T0, prior to surgery), during (T1: 1-3 months, and T2: 9-16 months following…
Early improvement as a predictor of remission and response in schizophrenia: Results from a naturalistic study
2009
AbstractObjectiveTo examine the predictive validity of early improvement in a naturalistic sample of inpatients and to identify the criterion that best defines early improvement.MethodsTwo hundred and forty-seven inpatients who fulfilled ICD-10 criteria for schizophrenia were assessed with the Positive And Negative Syndrome Scale (PANSS) at admission and at biweekly intervals until discharge from hospital. Remission was defined according to the recently proposed consensus criteria, response as a reduction of at least 40% in the PANNS total score from admission to discharge.ResultsReceiver operating characteristic (ROC) analyses showed that early improvement (reduction of the PANSS total sco…
Cigarette smoke causes caspase-independent apoptosis of bronchial epithelial cells from asthmatic donors
2015
BackgroundEpidemiologic studies have demonstrated important links between air pollution and asthma. Amongst these pollutants, environmental cigarette smoke is a risk factor both for asthma pathogenesis and exacerbation. As the barrier to the inhaled environment, the bronchial epithelium is a key structure that is exposed to cigarette smoke.ObjectivesSince primary bronchial epithelial cells (PBECs) from asthmatic donors are more susceptible to oxidant-induced apoptosis, we hypothesized that they would be susceptible to cigarette smoke-induced cell death.MethodsPBECs from normal and asthmatic donors were exposed to cigarette smoke extract (CSE); cell survival and apoptosis were assessed by fl…
Axis Rotation and Visually Induced Motion Sickness: The Role of Combined Roll, Pitch, and Yaw Motion
2011
A well-known phenomenon in aviation and in virtual environments such as simulators or computer games is motion sickness (MS). The amount of sensory conflict is thought to be responsible for the severity of MS, which should increase with the complexity of the simulated motion. The focus of the present study is on the direction and complexity of simulated body rotations in the genesis and severity of visually induced MS. The methods utilized for this study are as follows: Three simulated rollercoaster rides including translational movement in the fore-aft axis and additional rotational motion either in pitch only, along the pitch and roll axes, or in pitch, roll, and yaw were generated. The a…
Some physiological and psychological characteristics of myopic and non-myopic young men.
2009
As a part of a research project on the health and functional capacity of men at different ages a comparison of selected physiological and psychological characteristics of myopic and non-myopic 31–35 year-old men was made. The random sample studied consisted of 31 myopic and 100 non-myopic men. It was found that the body mass index and fat content were lower among the myopic than among the non-myopic. No significant differences were found in the elastic properties of skin, in blood pressure or in haematological assays studied between the groups. With respect to physical performance it was observed that the myopic had a higher aerobic capacity whereas there were no significant differences in …
