Normal-weight obesity and cardiometabolic risk : A 7-year longitudinal study in girls from prepuberty to early adulthood
2017
Objective: To study whether normal-weight obesity in childhood is associated with increased cardiometabolic risk in early adulthood. Methods: This study assessed data for 236 girls followed from prepuberty to early adulthood. Growth chart data were obtained from birth to 18 years. Body composition was assessed by dual-energy x-ray absorptiometry and cardiometabolic risk by calculating continuous clustered risk score (at ages 11, 14, and 18). The association of body weight status with cardiometabolic risk from childhood to early adulthood was examined. Results: Subjects with normal-weight obesity were virtually indistinguishable from their normal-weight lean peers in terms of relative body w…
Exercise as therapy for neurodevelopmental and cognitive dysfunction in people with a Fontan circulation: A narrative review
2023
People with a Fontan circulation are at risk of neurodevelopmental delay and disability, and cognitive dysfunction, that has significant implications for academic and occupational attainment, psychosocial functioning, and overall quality of life. Interventions for improving these outcomes are lacking. This review article discusses current intervention practices and explores the evidence supporting exercise as a potential intervention for improving cognitive functioning in people living with a Fontan circulation. Proposed pathophysiological mechanisms underpinning these associations are discussed in the context of Fontan physiology and avenues for future research are recommended.
Exploratory behaviour is not related to associative learning ability in the carabid beetle Nebria brevicollis
2020
Recently, it has been hypothesised that as learning performance and animal personality vary along a common axis of fast and slow types, natural selection may act on both in parallel leading to a correlation between learning and personality traits. We examined the relationship between risk-taking and exploratory behaviour and associative learning ability in carabid beetle Nebria brevicollis females by quantifying the number of trials individuals required to reach criterion during an associative learning task (‘learning performance’). The associative learning task required the females to associate odour and direction with refugia from light and heat in a T-maze. Further, we assessed learning …

Automated detection and localization system of myocardial infarction in single-beat ECG using Dual-Q TQWT and wavelet packet tensor decomposition
2020
Background and objective. It is challenging to conduct real-time identification of myocardial infarction (MI) due to artifact corruption and high dimensionality of multi-lead electrocardiogram (ECG). In the present study, we proposed an automated single-beat MI detection and localization system using dual-Q tunable Q-factor wavelet transformation (Dual-Q TQWT) denoising algorithm. Methods. After denoising and segmentation of ECG, a fourth-order wavelet tensor (leads × subbands × samples × beats) was constructed based on thediscretewavelet packet transform (DWPT), to represent the features considering the information of inter-beat, intra-beat, inter-frequency, and inter-lead. To reduce the t…

Menopause modulates the circulating metabolome: evidence from a prospective cohort study
2022
Abstract Aims We studied the changes in the circulating metabolome and their relation to the menopausal hormonal shift in 17β-oestradiol and follicle-stimulating hormone levels among women transitioning from perimenopause to early postmenopause. Methods and results We analysed longitudinal data from 218 Finnish women, 35 of whom started menopausal hormone therapy during the study. The menopausal transition was monitored with menstrual diaries and serum hormone measurements. The median follow-up was 14 months (interquartile range: 8–20). Serum metabolites were quantified with targeted nuclear magnetic resonance metabolomics. The model results were adjusted for age, follow-up duration, educat…
Exercise cardiac power and the risk of heart failure in men : A population-based follow-up study
2022
Background Little is known about exercise cardiac power (ECP), defined as the ratio of directly measured maximal oxygen uptake with peak systolic blood pressure during exercise on heart failure (HF) risk. We examined the association of ECP and the risk of HF. Methods This was a population-based cohort study of 2351 men from eastern Finland. The average time to follow-up was 25 years. Participants participated at baseline in an exercise stress test. A total of 313 cases of HF occurred. Results Men with low ECP (13.92 mL/mmHg, highest quartile), after adjusting for age. Low ECP was associated with a 1.96-fold risk (95%CI: 1.38 − 2.78, p < 0.001) of HF after additional adjustment for conventio…
Long-term effects of physical training on cardiac function and structure in adolescent cross-country skiers : a 6.5-year longitudinal echocardiograph…
2004
Margareetta Tummavuoren 6,5 vuoden seurantatutkimus antoi tietoa harjoittelun vaikutuksista nuorten kestävyysurheilijoiden sydämen rakenteeseen ja toimintaan. Hän selvitti myös maksimaalista toimintakykyä kuvaavan maksimaalisen hapenottokyvyn kehittymistä kestävyysharjoittelun vaikutuksesta. The purpose of this 6.5-year follow-up study was to investigate the impact of training on the structure and function of the heart of young endurance athletes with the help of echocardiographic variables and maximal oxygen uptake (O2max), which indicates the capacity of maximal cardiovascular function. This study also sought to determine at which age the structural and functional changes in the heart too…
