Factorial Structure and Psychometric Properties of a Brief Scale of the Condom Use Self-Efficacy for Spanish-Speaking People
2018
Background. Studies have shown the role played by perceived self-efficacy in explaining condom negotiation and condom use. Aims. The factorial structure and the psychometric properties of the Brief Condom Use Self-Efficacy Scale are presented. Method. The study included 368 men and 456 women aged 17 to 55 years ( Mage = 25.01, SD = 6.93). Results. Exploratory factor analysis yielded three factors: fear of rejection, impulse control, and condom acquisition and negotiation, which together accounted for 68% of the total variance. That structure was confirmed through confirmatory factor analysis. Cronbach’s alpha for the Brief Condom Use Self-Efficacy Scale was .71. The scale provided adequate…
Validation of TMMS-24 in Three Spanish-Speaking Countries: Argentina, Ecuador, and Spain
2021
Emotional intelligence (EI) is a fundamental skill related to different aspects of human life, such as psychological well-being or mood states. The present study has a triple objective: first, to explore the psychometric properties of the TMMS-24 in three Spanish-speaking countries (Argentina, Ecuador, and Spain)
Differences and Similarities between Allergic and Nonallergic Rhinitis in a Large Sample of Adult Patients with Rhinitis Symptoms
2010
<i>Background:</i> Allergic rhinitis (AR) and nonallergic rhinitis (NAR) may present with different clinical and laboratory characteristics. <i>Methods:</i> A total of 1,511 consecutive patients, aged 18–81 years, diagnosed with rhinitis, 56% females and 44% males, underwent complete allergic evaluation including skin prick test, blood eosinophil counts, nasal eosinophil counts, peak nasal inspiratory flow (PNIF) measurement and evaluation of nasal symptoms using a visual analog scale (VAS). <i>Results:</i> A total of 1,107 patients (73%)had AR, whereas 404 (27%) had NAR. Patients with NAR were older and predominantly female. A higher nasal eosinophils co…
Spatial variability of muscle activity during human walking: The effects of different EMG normalization approaches
2015
Human leg muscles are often activated inhomogeneously, e.g. in standing. This may also occur in complex tasks like walking. Thus, bipolar surface electromyography (sEMG) may not accurately represent whole muscle activity. This study used 64-electrode high-density sEMG (HD-sEMG) to examine spatial variability of lateral gastrocnemius (LG) muscle activity during the stance phase of walking, maximal voluntary contractions (MVCs) and maximal M-waves, and determined the effects of different normalization approaches on spatial and inter-participant variability. Plantar flexion MVC, maximal electrically elicited M-waves and walking at self-selected speed were recorded in eight healthy males aged 2…
Pressure pain thresholds: Subject factors and the meaning of peak pressures.
2017
Background The assessment of pressure pain has become an integral part in pain research. The distribution of pressure under a plunger can be uneven. However, measurements based on conventional devices show the applied force or mean pressure, failing to take local pressure peaks into account. Our main question was whether peak pressures under the probe are responsible for pain onset. Methods A force-controlled algometer was fitted with a newly developed pressure-indicating film. Pressure pain thresholds (PPTs) of 100 healthy subjects (57 men, age 18-66 years) were assessed at 29 sites across the body. Each site was measured three times, nonconsecutively and presented in randomized order. For…
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-…
Characteristics and Prognostic Value of Morning Dipping of Peak Expiratory Flow Rate in Stable Asthmatic Subjects
1985
Characteristics and prognostic relevance of morning dip of peak expiratory flow rate (PEFR) were evaluated in stable asthmatic subjects. Among 246 outpatients monitored four times daily for two weeks, 38 (group A) showed a significant difference between morning reading of PEFR and each of the others; they were compared to 38 randomly selected patients (group B) not showing morning dip in PEFR. Less frequent seasonal course, extrinsic pathogenesis, and sensitization to mites characterized group A; starting airflow limitation was more severe in those with morning dip, but no significant difference between mean PEFR measured throughout two weeks was found. At 6 to 12 weeks, morning dip was not…
Interaction of atenolol with furosemide and calcium and aluminum salts
1981
Six healthy subjects were treated with 100 mg atenolol. After a therapy-free interval of 4 wk the same subjects received the same dose of atenolol with furosemide, 40 mg, with calcium (as the lactate gluconate and carbonate), 500 mg, or with aluminum hydroxide, 5.6 gm. Atenolol alone and in combination was administered first as a single oral dose; a long-term 6-day treatment began 48 hr later. Addition of furosemide did not influence atenolol kinetics, but aluminum hydroxide led to an insignificant reduction (P greater than 0.05) of mean peak plasma levels of about 20% and of the area under the plasma concentration-time curve (AUC -infinity) from 5818 to 4353 ng ml-1 hr (P greater than 0.05…
An Internet-Based Self-Help Treatment for Fear of Public Speaking: A Controlled Trial
2010
Abstract This study offers data about the efficacy of “Talk to Me,” an Internet-based telepsychology program for the treatment of fear of public speaking that includes the most active components in cognitive-behavior therapy (CBT) for social phobia (exposure and cognitive therapies). One hundred twenty-seven participants with social phobia were randomly assigned to three experimental conditions: (a) an Internet-based self-administered program; (b) the same program applied by a therapist; (c) a waiting-list control group. Results showed that both treatment conditions were equally efficacious. In addition, Talk to Me and the same treatment applied by a therapist were more efficacious than the…
Expiratory airflow obstruction due to tracheostomy tube: A spirometric study in 50 patients
2018
OBJECTIVES Tracheostomy is commonly used in intensive care units and in head and neck departments. Airway obstruction due to occluded cuffless tracheostomy tubes themselves remains unknown, although capping trials are commonly used before decannulation. The aim of this study was to evaluate the extent to which airway obstruction can be caused by occluded cuffless tubes in patients who underwent head and neck surgery. DESIGN Prospective Research Outcome. SETTINGS University teaching hospital. PARTICIPANTS Fifty patients requiring transient tracheostomy after head and neck surgery. MAIN OUTCOME MEASURES A flow-volume loop (FVL) through the mouth using a portable spirometer, with the occluded …
