Associations Between Physical and Executive Functions Among Community-Dwelling Older Men and Women
2022
Walking is a complex task requiring the interplay of neuromuscular, sensory, and cognitive functions. Owing to the age-related decline in cognitive and physical functions, walking may be compromised in older adults, for cognitive functions, especially poor performance in executive functions, is associated with slow walking speed. Hence, the aim of this study was to investigate the associations between different subdomains of executive functions and physical functions and whether the associations found differ between men and women. Multiple linear regression analysis was performed on data collected from 314 community-dwelling older adults who did not meet physical activity guidelines but had…
Influence of beliefs about romantic love on the justification of abusive behaviors among early adolescents
2021
Introduction Romantic experiences during adolescence have an important influence on functioning later in life. Romantic love has been associated with the acceptance of abusive behaviors. This study examined the relationship between myths of romantic love and the perceived severity of different types of abusive behaviors, as well as the influence of gender. Methods The sample comprised 448 Spanish adolescents (M = 12.92 years old; SD = 0.85), of which 50.3% were male and 49.7% were female. Participants were evaluated in the school setting. The Perception of Abuse Scale and the Myths, Fallacies, and Misconceptions about Romantic Love Scale were administered. Results Statistically significant …
Cross-linguistic variation in the neurophysiological response to semantic processing: Evidence from anomalies at the borderline of awareness
2014
The N400 event-related brain potential (ERP) has played a major role in the examination of how the human brain processes meaning. For current theories of the N400, classes of semantic inconsistencies which do not elicit N400 effects have proven particularly influential. Semantic anomalies that are difficult to detect are a case in point ("borderline anomalies", e.g. "After an air crash, where should the survivors be buried?"), engendering a late positive ERP response but no N400 effect in English (Sanford, Leuthold, Bohan, & Sanford, 2011). In three auditory ERP experiments, we demonstrate that this result is subject to cross-linguistic variation. In a German version of Sanford and colleagu…
Modality-independent recruitment of inferior frontal cortex during speech processing in human infants
2018
Despite increasing interest in the development of audiovisual speech perception in infancy, the underlying mechanisms and neural processes are still only poorly understood. In addition to regions in temporal cortex associated with speech processing and multimodal integration, such as superior temporal sulcus, left inferior frontal cortex (IFC) has been suggested to be critically involved in mapping information from different modalities during speech perception. To further illuminate the role of IFC during infant language learning and speech perception, the current study examined the processing of auditory, visual and audiovisual speech in 6-month-old infants using functional near-infrared s…
Six Hundred Meter–Run and Broken 800’s Contribution to Pacing Improvement in Eight Hundred Meter–Athletics
2013
Little is known about the influence of speed endurance workouts on the improvement of pacing strategies in the 800-m running event. This study aims to analyze it, comparing continuous repetitions vs. interval training workouts. Because we hypothesize that pacing is susceptible to expertise, there might be age differences. Nineteen male 800-m runners (age: 21.36 ± 5.26, season best [SB]: 117.14 ± 5.18 seconds) were tested. Athletes were asked to run 1 × 600 m (6r) at 100% (SB) and 2 × 4 (200 m per 30 seconds) per 15 minutes (B8) at 102% (SB), counterbalanced and randomized within 1 week of difference. Pacing strategy (velocity dynamics) was analyzed by means of time differences in 200-m segm…
Age-related decline in body cell mass in elderly men and women, determined by a noninvasive nuclear technique: Effects of physical activity and dieta…
2001
The body cell mass (BCM) represents the actively metabolizing cellular components of the human body. In this study, the hypothesis was tested that physical activity and a sufficient dietary intake of potassium attenuate the age-related decline in BCM in the elderly. Cross-sectional data were collected in 82 male and 79 female non-institutionalized elderly (60–90 years) from Mainz, Germany, and were analyzed by age groups. BCM was calculated from total body potassium, measured by whole-body counting of naturally occurring 40K. Physical activity level (PAL) was assessed by a standardized questionnaire. Dietary intake of potassium (DIP) was estimated from a 7-day food diary. The results showed…
Differential prognostic impact of type 2 diabetes mellitus in women and men with heart failure with preserved ejection fraction
2020
Introduction and objectives Type 2 diabetes mellitus (DM2) is a common comorbidity in patients with heart failure (HF) with preserved ejection fraction (HFpEF). Previous studies have shown that diabetic women are at higher risk of developing HF than men. However, the long-term prognosis of diabetic HFpEF patients by sex has not been extensively explored. In this study, we aimed to evaluate the differential impact of DM2 on all-cause mortality in men vs women with HFpEF after admission for acute HF. Methods We prospectively included 1019 consecutive HFpEF patients discharged after admission for acute HF in a single tertiary referral hospital. Multivariate Cox regression analysis was used to …
Decrease in Serum Vitamin D Level of Older Patients with Fatigue
2019
Fatigue is characterized by reduced energy level, decreased muscle strength, and a variable degree of cognitive impairment. Recent evidences seem to link vitamin D deficiency to fatigue. The aim of this study was to assess and compare vitamin D status in a cohort of older subjects with and without fatigue. We recruited a total of 480 subjects, 240 patients with fatigue and 240 controls without fatigue, from the Cannizzaro Hospital of Catania (Italy). Fatigue severity was measured by the fatigue severity scale, whereas mental and physical fatigue were measured through the Wessely and Powell fatigue scale, respectively. We also measured several blood parameters and 25-OH vitamin D. Subjects w…
The heritability of depressive symptoms: multiple informants and multiple measures
2002
Background: Earlier research suggests large rater differences in heritability estimates of children's depressive symptoms in the context of significant age and sex-limitation effects. Methods: With data from an ongoing, population-based twin-family study, we estimated genetic and environmental influences on children's depression with models allowing for sex-specific effects. Our assessments of twins included self-reports and ratings made by their classmate peers, their parents and their teachers, allowing estimates of genetic and environmental effects with data from different informants. Model-fitting used maximum likelihood estimation of log-transformed data from a sample of 1,366 11- and …
Long-term outcomes in men and women with ST-segment elevation myocardial infarction and incomplete reperfusion after a primary percutaneous coronary …
2019
Background The failure of reperfusion therapy in patients with ST-segment elevation myocardial infarction (STEMI) is more frequent than considered previously. Aim To evaluate sex-related differences in long-term outcomes in patients with STEMI and incomplete infarct-related artery reperfusion after a primary percutaneous coronary intervention. Patients and methods Of consecutive 42 752 patients with STEMI hospitalized between 2009 and 2011 in Poland, we analyzed a group of 766 (35%) women and 1453 (65%) men with less than thrombolysis in myocardial infarction (TIMI) flow grade 3 following a primary percutaneous coronary intervention. Results In the 2-year follow-up, the mortality rate among…
