Job absenteeism and arterial hypertension: results of a hypertension control program.
1992
This study reports the findings of one of the stages of a programme for the detection and control of arterial hypertension, started in I980 in an automobile company with a workforce of 9,782. In the initial screening, 522 hypertensive males were found using epidemiological criteria and 206 of these fulfilled the criteria of definite hypertension. The objective of this study consisted of evaluating, 9 years after the start of the program, the indirect cost in terms of the reduction in the morbidity indicator-temporary work incapacity (TWI). Analysis is based on a comparison of the prevalence of hypertension in the population when the program was begun (6%) and in 1989 (9.8%). It can be obser…
Trace elements in scalp hair samples from patients with relapsing-remitting multiple sclerosis
2015
Background Epidemiological studies have suggested a possible role of trace elements (TE) in the etiology of several neurological diseases including Multiple Sclerosis (MS). Hair analysis provides an easy tool to quantify TE in human subjects, including patients with neurodegenerative diseases. Objective To compare TE levels in scalp hair from patients with MS and healthy controls from the same geographic area (Sicily). Methods ICP-MS was used to determine the concentrations of 21 elements (Ag, Al, As, Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Rb, Sb, Se, Sr, U, V and Zn) in scalp hair of 48 patients with relapsing–remitting Multiple Sclerosis compared with 51 healthy controls. Results MS …
Socio-economic cost and health-related quality of life of burn victims in Spain
2008
Abstract Objectives The aim of the study was to determine the economic burden (direct and indirect costs) of burn victims and the impact of burn on health-related quality of life in Spain. Methods In 2003, a cross-sectional study was carried out with 898 burned people. Data regarding demographic features, health resource use, informal care, indirect costs and quality of life were prospectively collected through hospital admission databases and questionnaires filled out by burn victims and caregivers. Results The mean annual cost (direct and indirect) per burn patient was US$ 99,773. The most important categories of costs were those of in-patient care and temporary and permanent disability. …
Basal metabolic rate in narcoleptic patients.
2009
PATIENTS SUFFERING FROM NARCOLEPSY TEND TO BE OBESE.1,2 AMONG OTHER HYPOTHESES LOWER RESTING ENERGY EXPENDITURE HAS BEEN SUSPECTED to be the cause of the narcolepsy-associated obesity.3,4 The use of indirect calorimetry is a well-established noninvasive method to measure the energy expenditure (EE) and the resting (basal) metabolic rate (BMR). Chabas et al. recently published an evaluation of eating behavior and energy balance of 7 typical and 6 atypical narcoleptic patients and 9 controls using indirect calorimetry. Narcoleptic patients were found to have a lower energy expenditure (EE) than controls (n = 13, P = 0.07). Thus, it was concluded that narcolepsy associated obesity could be the…
Lattice Corneal Dystrophy Type 1
2014
PURPOSE To evaluate the question whether lattice corneal dystrophy type 1 (LCD1) is of epithelial or stromal origin. METHODS The landmark of advanced LCD1 shows central superficial haze and paracentral stromal lattice lines. In 16 eyes of 8 affected individuals of 2 families, a penetrating keratoplasty was performed. The follow-up was 8 to 16 years after penetrating keratoplasty. Slit-lamp documentation of the patients was evaluated in direct and indirect illumination with dilated pupil to assess the horizontal and vertical pattern of new deposits on the corneal graft. Three affected patients of 2 families are demonstrated in detail. A DNA analysis was performed. RESULTS Gene identification…
Exploring directionality in spontaneous heart period and systolic pressure variability interactions in humans: implications in the evaluation of baro…
2004
Although in physiological conditions RR interval and systolic arterial pressure (SAP) are likely to interact in a closed loop, the traditional cross-spectral analysis cannot distinguish feedback (FB) from feedforward (FF) influences. In this study, a causal approach was applied for calculating the coherence from SAP to RR ( Ks-r) and from RR to SAP ( Kr-s) and the gain and phase of the baroreflex transfer function. The method was applied, compared with the noncausal one, to RR and SAP series taken from 15 healthy young subjects in the supine position and after passive head-up tilt. For the low frequency (0.04–0.15 Hz) spectral component, the enhanced FF coupling ( Kr-s = 0.59 ± 0.21, signi…
Initial Evaluation of a Smoking Cessation Program Incorporating Physical Activity Promotion to Greek Adults in Antismoking Clinics
2012
The purpose of this study was to evaluate an initial application of a smoking cessation program that integrated the promotion of physical activity (PA) as a cessation aid to Greek adults in antismoking clinics. From an initial pool of 50, 12 men and 28 women from Central Greece completed the program, and 18 of them succeeded in quitting for 1 year after the program. Additionally, after the program, they increased their PA. Suggestions for future applications of the program are further discussed. peerReviewed
Neglect-like effects induced by tDCS modulation of posterior parietal cortices in healthy subjects
2011
Background Repetitive transcranial magnetic stimulation (rTMS) over right posterior parietal cortex was shown to induce interference on visuospatial perception in healthy subjects. Transcranial direct current stimulation (tDCS) is another noninvasive brain stimulation technique that works modulating cortical activity. It is applied through easy to use, noncostly, and portable devices. Objective/Hypothesis The aim of the current study was to investigate if the novel approach of “dual” stimulation over parietal cortices compared with the unilateral (right) cathodal one is able to induce greater and/or longer-lasting neglect-like effects in normal subjects performing a computerized visuospatia…
The costs of social anxiety disorder: The role of symptom severity and comorbidities
2013
Abstract Background Social anxiety disorder (SAD) is associated with low direct costs compared to other anxiety disorders while indirect costs tend to be high. Mental comorbidities have been identified to increase costs, but the role of symptom severity is still vague. The objective of this study was to determine the costs of SAD, and to explore the impact of symptoms and comorbidities on direct and indirect costs. Methods Baseline data, collected within the SOPHO-NET multi-centre treatment study ( N =495), were used. Costs were calculated based on health care utilization and lost productivity. Symptom severity was measured with the Liebowitz-Social-Anxiety-Scale; comorbidities were include…
A low resting metabolic rate is associated with metabolic syndrome
2007
Background & aims: The metabolic syndrome is associated with central accumulation of fat. Previous studies showed that some obese subjects are characterized by a sparing energy metabolism. The aim of this study was to investigate whether obese subjects with metabolic syndrome have a lower resting metabolic rate than obese subjects without metabolic syndrome. Methods: Forty obese subjects were divided into three groups according to the presence of metabolic syndrome and type 2 diabetes; 15 non-obese healthy control subjects were also enrolled. Body composition (bio-impedance analysis) and resting metabolic rate (indirect calorimetry) were performed. Results: The group with metabolic syndrome…
