Reproducibility of pulse wave velocity and augmentation index derived from non-invasive occlusive oscillometric tonometry analysis in adolescents
2018
The aim of this study was to investigate the short-term reproducibility of aortic pulse wave velocity (PWVao) and augmentation index (AIx%) assessed by the non-invasive oscillometric device. Altogether of 55 (19 boys, 36 girls) adolescents 16-19-years-of-age participated in the study. PWVao and AIx% were measured during the same laboratory visit at 2 min intervals using the Arteriograph™ device. Peak oxygen uptake (VO2peak ) was assessed by the maximal exercise test on a cycle ergometer and body fat percentage by bioelectrical impedance analysis. We studied reproducibility using intraclass correlation coefficients (ICC), coefficient variation with the root-means-square method expressed as p…

Associations of cardiorespiratory fitness, adiposity, and arterial stiffness with cognition in youth
2020
Abstract Purpose To investigate the associations of cardiorespiratory fitness, adiposity, and arterial stiffness with cognition in 16‐ to 19‐year‐old adolescents. Methods Fifty four adolescents (35 girls; 19 boys) participated in the study. Peak oxygen uptake (V̇O2peak) and peak power output (Wmax) were measured by the maximal ramp test on a cycle ergometer and ventilatory threshold (VT) was determined with ventilation equivalents. Lean mass (LM) and body fat percentage (BF%) were measured using a bioelectrical impedance analysis. Aortic pulse wave velocity (PWVao) and augmentation index (AIx%) were measured by a non‐invasive oscillometric device. Working memory, short term memory, visual l…
The Usefulness of Bioelectrical Impedance Analysis in Differentiating Dyspnea Due to Decompensated Heart Failure
2007
Acute dyspnea poses a diagnostic challenge for physicians, and the current methods in differentiating cardiac from non-cardiac causes have been limited to date. Recently, the brain natriuretic peptide (BNP) rapid test has been validated in the emergency room. Nevertheless, the early accumulation of fluid in the interstitial space in the body and in the lungs, which characterizes patients with ADHF, is well estimated by BIA. We investigate whether bioelectrical impedance analysis (BIA) can serve as a noninvasive diagnostic tool in the differential diagnosis of acute decompensated heart failure (ADHF) in the emergency department (ED).A total of 292 patients presenting with acute dyspnea to th…
Assessing appendicular skeletal muscle mass with bioelectrical impedance analysis in free-living Caucasian older adults
2015
Background & aims: Aging is characterized by a loss of appendicular skeletal muscle mass (ASMM) leading to physical disability and death. Bioelectrical impedance analysis (BIA) is reliable in estimating ASMM but no prediction equations are available for elderly Caucasian subjects. The aim of the study was to develop and validate an equation derived from bioelectrical impedance analysis (BIA) to predict appendicular skeletal muscle mass (ASMM) in healthy Caucasian elderly subjects, taking dual X-ray absorptiometry (DXA) as the reference method, and comparing the reliability of the new equation with another BIA-based model developed by Kyle etal. (Kyle UG, Genton L, Hans D, Pichard C, 200…
Ultra Trail Performance is Differently Predicted by Endurance Variables in Men and Women
2020
AbstractThe study aimed to assess the relationship between peak oxygen uptake, ventilatory thresholds and maximal fat oxidation with ultra trail male and female performance. 47 athletes (29 men and 18 women) completed a cardiopulmonary exercise test between 2 to 4 weeks before a 107-km ultra trail. Body composition was also analyzed using a bioelectrical impedance weight scale. Exploratory correlation analyses showed that peak oxygen uptake (men: r=–0.63, p=0.004; women: r=–0.85, p < 0.001), peak speed (men: r=–0.74, p < 0.001; women: r=–0.69, p=0.009), speed at first (men: r=–0.49, p=0.035; women: r=–0.76, p=0.003) and second (men: r=–0.73, p < 0.001; women: r=–0.76, p=0.003) vent…
Troponin I release after intravenous treatment with high furosemide doses plus hypertonic saline solution in decompensated heart failure trial (Tra-H…
2012
Background High values of cardiac troponin in acute decompensated congestive heart failure (ADHF) identify patients at higher risk and worsened prognosis. A cardiac troponin increase during therapy indicates the need for more appropriate intervention, aimed at compensating cardiac disease and effectively minimizing myocardial wall stress and subsequent cytolysis. This study evaluated the effects of an intravenous high dose of furosemide with (group A) or without small volume hypertonic saline solution (HSS) (group B) on myocardial cytolysis in patients with ADHF. Methods A total of 248 consecutive patients with ADHF (148 men, mean age 74.9 ± 10.9 years) were randomly assigned to group A or …
Early and personalized ambulatory follow-up to tailor furosemide and fluid intake according to congestion in post-discharge heart failure
2010
Congestive heart failure (CHF) worsening is a worldwide cause of rehospitalization and mortality, specially during the early period after hospitalization. Fluid accumulation plays a key role in the pathophysiology of both acute heart decompensation and disease progression. The effective use of drugs to maintain restored clinical stabilization in recently discharged patients is a difficult task, and it relies on matching the most appropriately tailored therapy to specific clinical profiles. However, no successful treatment has been shown to reduce post-discharge readmission. We evaluated in a case-control study the effectiveness of an early and personalized congestion-guided ambulatory progr…
Body composition and changes in health-related quality of life in older age: a 10-year follow-up of the Helsinki Birth Cohort Study
2020
Abstract Purpose Most studies examining the associations between body composition and health-related quality of life (HRQoL) in older age have been cross-sectional and analyzed only fat or lean mass. Hence, it is poorly known whether fat and lean mass are independently associated with subsequent changes in HRQoL. We investigated whether baseline lean and fat mass are associated with changes in HRQoL over a 10-year period in older adults. Methods We studied 1044 men and women from the Helsinki Birth Cohort Study (age 57–70 years at baseline). Bioelectrical impedance analysis was used to derive baseline fat mass index (FMI, fat mass/height2) and lean mass index (lean mass/height2), dichotomiz…
Moderate-Vigorous Physical Activity across Body Mass Index in Females : Moderating Effect of Endocannabinoids and Temperament

The funders had no role in the study design, data collection and analysis, decision to publish, or preparation of the manuscript. Endocannabinoids and temperament traits have been linked to both physical activity and body mass index (BMI) however no study has explored how these factors interact in females. The aims of this cross-sectional study were to 1) examine differences…
