Normal reference values of multilayer longitudinal strain according to age decades in a healthy population: A single-centre experience.
2017
Aims Recent advancements in echocardiographic technology allow to analyse myocardial strain in multiple layers. Little is known about the impact of age on layer-specific longitudinal strain in healthy subjects. The aim of this study was to analyse the influence of age on multilayer longitudinal strain and establish normal reference values of layer-specific strain according to age decades in a healthy population referring to our echo laboratory using 2D speckle-tracking echocardiography with layer-specific software. Methods and results Two-hundred sixty-six healthy, consecutive subjects (mean age = 39.2 ± 17.5 years, women/men = 137/129), free of cardiovascular risk factors, were enrolled. S…
3D echocardiographic reference ranges for normal left ventricular volumes and strain: results from the EACVI NORRE study
2017
International audience; Aim: To obtain the normal ranges for 3D echocardiography (3DE) measurement of left ventricular (LV) volumes, function, and strain from a large group of healthy volunteers. Methods and results: A total of 440 (mean age: 45 ± 13 years) out of the 734 healthy subjects enrolled at 22 collaborating institutions of the Normal Reference Ranges for Echocardiography (NORRE) study had good-quality 3DE data sets that have been analysed with a vendor-independent software package allowing homogeneous measurements regardless of the echocardiographic machine used to acquire the data sets. Upper limits of LV end-diastolic and end-systolic volumes were larger in men (97 and 42 mL/m2)…
The effect of acupuncture on oral microcirculation in healthy volunteers: an exploratory study.
2009
Background Acupuncture is a therapeutic technique currently used in the treatment of many pathologies. The aim of this study is to evaluate the potential effect of acupuncture on “in vivo” variations in oral microcirculation in healthy subjects. Methods An exploratory study was conducted on 40 healthy subjects: 20 cases (mean 55.90, SD 16.04) and 20 controls (mean 51, SD 11.91). Videocapillaroscopy was used to detect variations in oral microcirculation. This method permits an accurate and non-invasive in vivo study of the capillaries of the oral mucous. The site selected for this pilot study is the lower lip since it is the simplest to investigate and is more readily accessible. Assessments…
Risk factors of oral candidosis: a twofold approach of study by fuzzy logic and traditional statistic.
2007
Abstract Objective To assess a panel of risk factors associated to oral candidosis (OC) onset and its chronic maintenance by means of fuzzy logic (FL) approach and statistical traditional methodology (STM); to investigate their casual relationship within a multifactorial framework. Design Case–control study. Setting One hospital-based clinic. Patients Eighty-nine patients with OC infection microbiologically diagnosed and 98 healthy subjects were consecutively recruited. Outcome measurements Anamnestic and clinical evaluations for OC, microbiological assessment (i.e. culture, CFU/mL counting and identification) were performed. The commonest predisposing factors for OC onset and its chronic s…
Assessment of corneal thickness and tear meniscus during contact-lens wear
2014
To assess the effect of seven different daily disposable contact lenses upon corneal thickness, as well as upon tear meniscus volume, by using optical coherence tomography (OCT).Thirty-four young healthy subjects wore seven different types of daily disposable soft contact lenses, each for a period of 12h: Delefilcon A, Nelfilcon A, Omafilcon A, Filcon II3, Narafilcon A, Etafilcon A and Hilafilcon B. Central and mid-peripheral corneal thickness and lower tear meniscus volume (TMV) were measured using an OCT device during contact-lens wear at 4-h intervals throughout a 12-h period. Measurements were also recorded without any contact lenses being worn during a day.In the no-lens scenario a sma…
The role of lifestyle behaviour on the risk of hypertension in the SUN cohort: The hypertension preventive score
2019
Lifestyles may influence the risk of hypertension. Our objective was to assess the association between a healthy-lifestyle score and the incidence of hypertension. The SUN Project is a dynamic, prospective cohort of Spanish university graduates (1999-2014). Among 14,057 participants initially free of hypertension, we assessed the influence of lifestyle-related factors based on a 10-item score that we previously reported to be associated with lower risk of major cardiovascular events. However, we focused on factors related to hypertension risk according to previous scientific evidence and international clinical guidelines and constructed a 6-item score including: no smoking, moderate-to-high…
German validation of the conners adult ADHD rating scale-self-report: confirmation of factor structure in a large sample of participants with ADHD.
2013
Objective: The Conners Adult ADHD Rating Scales (CAARS) assess symptoms specific to adults that are frequently used and have been translated into German. The current study tests the factor structure of the CAARS in a large sample of German adults with ADHD and compares the means of the CAARS subscales with those of healthy German participants. Method: CAARS were completed by 466 participants with ADHD and 851 healthy control participants. Confirmatory factor analysis was used to establish model fit with the American original. Comparisons between participants with ADHD and healthy controls and influences of gender, age, and degree of education were analyzed. Results: Confirmatory factor anal…
Contributions of individual muscles to the sagittal- and frontal-plane angular accelerations of the trunk in walking.
2013
This study was conducted to analyze the unimpaired control of the trunk during walking. Studying the unimpaired control of the trunk reveals characteristics of good control. These characteristics can be pursued in the rehabilitation of impaired control. Impaired control of the trunk during walking is associated with aging and many movement disorders. This is a concern as it is considered to increase fall risk. Muscles that contribute to the trunk control in normal walking may also contribute to it under perturbation circumstances, attempting to prevent an impending fall. Knowledge of such muscles can be used to rehabilitate impaired control of the trunk. Here, angular accelerations of the t…
Differential association of default mode network connectivity and rumination in healthy individuals and remitted MDD patients
2016
Rumination is associated with increased default-mode network (DMN) activity and functional connectivity (FC) in depressed and healthy individuals. In this study, we sought to examine the relationship between self-reported rumination and resting-state FC in the DMN and cognitive control networks in 25 remitted depressed patients and 25 matched healthy controls using independent component and seed-based analyses. We also explored potential group differences in the global pattern of resting-state FC. Healthy subjects with increased levels of rumination exhibited increased anterior DMN connectivity with the posterior DMN and the dorsal attention network and low connectivity within the anterior …
Ocular surface assessment in soft contact lens wearers; the contribution of tear osmolarity among other tests.
2014
: Purpose: To determine whether tear osmolarity contributes to the assessment of the ocular surface in soft contact lens (CL) wearers. Methods: Prospective, case–control series in 44 CL wearers (28 tolerant and 16 intolerant) and 34 healthy subjects. Every patient underwent a thorough ophthalmic examination with a tear osmolarity test (TearLab System), conjunctival impression cytology and meibomian lipid sampling. Symptoms, break-up time (BUT), tear osmolarity, conjunctival expression of HLA-DR and meibomian fatty acid composition were evaluated. Results: Tear osmolarity did not differ between controls and CL wearers (p = 0.23). Flow cytometry results expressed in antibody-binding capaci…
