Combining physiological measures in the detection of concealed information.
2008
Meta-analytic research has confirmed that skin conductance response (SCR) measures have high validity for the detection of concealed information. Furthermore, cumulating research has provided evidence for the validity of two other autonomic measures: Heart rate (HR) and Respiration Line Length (RLL). In the present report, we compared SCR detection efficiency with HR and RLL, and investigated whether HR and RLL provide incremental validity to electrodermal responses. Analyses were based on data from 7 different samples covering 275 guilty and 53 innocent examinees. Results revealed that the area under the ROC curve was significantly higher for SCR than for HR and RLL. A weighted combination…
Inverse Effects of Midlife Occupational and Leisure Time Physical Activity on Mobility Limitation in Old Age-A 28-Year Prospective Follow-Up Study
2014
Objectives: To evaluate in a sample of initially middle-aged municipal employees whether leisure time (LPA) or occupational physical activity (OPA) was associated with mobility limitation (ML) in old age. Design: Prospective population-based follow-up. Setting: Municipalities in Finland. Participants: Public sector employees from the Finnish Longitudinal Study on Municipal Employees (FLAME) initially aged 44 to 58 (N = 5,200). Measurements: Baseline data were collected in 1981, including LPA (average exercise within previous year: inactive (no exercise), moderate (some form of exercise ?1 time per week), vigorous (brisk exercise ?1 time per week)) and OPA (usual activities at work within pr…
Accommodative stimulus-response curves to low-pass filtered natural images
2018
To assess how the monocular steady-state accommodative stimulus-response curve is modified when viewing low-pass filtered natural images. Eighteen adult subjects participated in the study. The accommodative stimulus-response curve was objectively assessed by means of a Hartmann-Shack wavefront sensor. Measurements were taken at different accommodative demands. Target images were low-pass filtered versions of a natural image that were obtained applying different digital spatial filters that limited the spatial frequency content of the natural image. Cutoff spatial frequencies were set at 30, 21, and 15 cycles per degree (cy/deg). Mean data obtained for each target were fitted to linear model…
Spontaneous regression of multiple melanocytic nevi after melanoma: report of 3 cases.
2014
Complete spontaneous regression of multiple melanocytic nevi after melanoma is an extremely rare phenomenon. We report 3 cases of patients with a history of melanoma that showed regression of almost all melanocytic nevi over time. One of the patients had 2 simultaneous primary cutaneous melanomas without metastasis. In the other 2 patients, regression of the melanocytic nevi was seen after the development of metastasis in lymph nodes. These patients had spontaneously developed an efficient immune response against melanocytes, and they would represent paradigmatic examples of the spontaneous immune responses in melanoma patients. Better understanding of the mechanisms involved in the complet…
Analysis of LDL and HDL size and number by nuclear magnetic resonance in a healthy working population: The LipoLab Study
2020
Background and aim Atherosclerosis is the underlying process in cardiovascular disease (CVD), the first cause of death in developed countries. We aimed to identify people with no known CVD and normal values of LDL-C and HDL-C, but with alterations in the number and size of lipoprotein particles (as measured by nuclear magnetic resonance [NMR]) and to analyse their sociodemographic, clinical and biochemical characteristics. Methods Cross-sectional study in occupational risks prevention centre in Castellon (Spain) in 2017 and 2018, in consecutively recruited adults (18-65 years) with no known CVD. Sociodemographic, clinical and biochemical variables were collected. Lipid profiles were analyse…
Alcohol and Cannabis Intake in Nursing Students
2019
Background and objectives: Drug misuse among young people has become a major worldwide health concern. The present study analyzes substance misuse and its social and personal consequences in young university students. Materials and Methods: Screening of alcohol misuse was based on the Alcohol Use Disorder Identification Test (AUDIT), while screening of substance-related risks and problems was performed with the Car, Relax, Alone, Forget, Friends, Trouble (CRAFFT) score. Results: The population was composed of nursing students at the University of Valencia (Valencia, Spain) (n = 185). More than 50% of the surveyed students reported alcohol intake based on the CRAFFT scale
EMG, heart rate, and accelerometer as estimators of energy expenditure in locomotion.
2014
AB Purpose: Precise measures of energy expenditure (EE) during everyday activities are needed. This study assessed the validity of novel shorts measuring EMG and compared this method with HR and accelerometry (ACC) when estimating EE. Methods: Fifty-four volunteers (39.4 +/- 13.9 yr) performed a maximal treadmill test (3-min loads) including walking with different speeds uphill, downhill, and on level ground and one running load. The data were categorized into all, low, and level loads. EE was measured by indirect calorimetry, whereas HR, ACC, and EMG were measured continuously. EMG from quadriceps (Q) and hamstrings (H) was measured using shorts with textile electrodes. Validity of the met…
A satisfaction survey of opioid-dependent clients at methadone treatment centres in Spain
2002
A survey was carried out to evaluate the satisfaction with methadone treatment centres of methadone-maintained opioid-dependent patients from Spain. Independent interviewers asked 505 consecutively arriving clients from 20 randomly selected centres (14 conventional centres, two bus units, and four prisons) to participate; 370 (73.3%) clients agreed to fill out the questionnaire, and 351 (69.5%) completed it. Satisfaction was assessed using the Verona Service Satisfaction Scale for methadone treatment (VSSS-MT). The prison sub-sample (n=43) was excluded from overall analysis because survey acceptance and satisfaction was very different in prisons than in the other centres. Mean overall satis…
Transthoracic three-dimensional echocardiographic volumetry of distorted left ventricles using rotational scanning
1997
The purpose of this study was to evaluate the relation of transthoracic three- and two-dimensional echocardiographic left ventricular volumetry to cineventriculographic volumetry. Twenty-five patients with distorted left ventricles were included in the study. To demonstrate the impact of acquiring data by rotational scanning, we performed three- and two-dimensional echocardiography in 36 latex ventricles with data acquisition in different areas of the ultrasound sectors. Interobserver and intraobserver variability were calculated to test for reproducibility. The three-dimensional imaging system consisted of a rotation motor device, a transthoracic 2.5 MHz transducer, a conventional ultrasou…
Estimation of the age of majority through radiographic evaluation of the third molar maturation degree
2020
Background Although the third molar is the tooth with the greatest anatomical and developmental variability, some authors consider it important to estimate whether a subject is of legal age or not. The Demirjian’s technique is the most widely used tool to estimate dental age and was therefore used in our study to assess possible correlation between the age of majority and the maturational degree of the lower third molars, evaluated through radiographic images. Material and Methods This observational transversal study was conducted on 180 panoramic radiographs from consecutive patients. The degree of maturation of the lower third molar was independently classified by two observers, according…
