Modulation of Neocortical Development by Early Neuronal Activity: Physiology and Pathophysiology.
2017
Animal and human studies revealed that patterned neuronal activity is an inherent feature of developing nervous systems. This review summarizes our current knowledge about the mechanisms generating early electrical activity patterns and their impact on structural and functional development of the cerebral cortex. All neocortical areas display distinct spontaneous and sensory-driven neuronal activity patterns already at early phases of development. At embryonic stages, intermittent spontaneous activity is synchronized within small neuronal networks, becoming more complex with further development. This transition is accompanied by a gradual shift from electrical to chemical synaptic transmiss…
Comparative validity of the ASSO - Food Frequency Questionnaire for the web-based assessment of food and nutrients intake in adolescents
2015
Background : A new web-based food frequency questionnaire (the ASSO–FFQ) was developed within the ASSO Project funded by the Italian Ministry of Health. Objective : The aim of the present study is to assess the validity of the ASSO–FFQ at food groups, energy, and nutrients level. Design and subjects : The validation study compared the ASSO–FFQ against a weighted food record (WFR) measuring foods, beverages and supplements intake, compiled during the week following the ASSO–FFQ administration. Ninety-two subjects aged 14–17, recruited from secondary schools in Palermo (Italy), completed the ASSO–FFQ and WFR. The intake of 24 food groups, energy, and 52 nutrients were taken as main outcomes. …
Modulation of muscle-tendon interaction in the human triceps surae during an energy dissipation task.
2017
The compliance of elastic elements allows muscles to dissipate energy safely during eccentric contractions. This buffering function is well documented in animal models but our understanding of its mechanism in humans is confined to non-specific tasks, requiring a subsequent acceleration of the body. The present study aimed to examine the behaviour of the human triceps surae muscle-tendon unit (MTU) during a pure energy dissipation task, under two loading conditions. Thirty-nine subjects performed a single-leg landing task, with- and without added mass. Ultrasound measurements were combined with 3D kinematics and kinetics to determine instantaneous length changes of MTUs, muscle fascicles, A…

Körperliche Aktivität und deren Effekte auf das Burn-out-Syndrom
2020
ZusammenfassungDas vorliegende Review legt dar, dass regelmäßige körperliche Aktivität einen positiven Einfluss auf die Burn-out-Symptomatik hat. Mittels einer systematischen Literaturrecherche wurden die möglichen Effekte untersucht und die Evidenz mithilfe des Standard Index of Convergence (SIC) bewertet. Der SIC lag in den Längsschnittstudien bei SIC (3) = -1, während er in den Interventionsstudien bei SIC (6) = -0,50 lag. Daher ist jeweils von einer moderat star ken Evidenz auszugehen, dass körperliche Aktivität einen positiven gesundheitlichen Effekt auf das Burn-out-Syndrom hat. Aufgrund der Heterogenität der Erhebungstools und der Studienlage ist es notwendig, weitere qualitativ hoch…
Physical capacity in performing daily activities is reduced in scleroderma patients with early lung involvement
2015
Background and Aims Patients with systemic sclerosis (SSc) often complain reduced capacity at submaximal exercise; conversely, physical capacity in performing daily duties has never been measured in SSc. The aim of this study is to evaluate this performance and its correlates, in patients with SSc compared with healthy controls, in a free-living setting. Methods Twenty-seven outpatients with stable SSc and 11 controls were recruited. Physical activity was assessed by portable multiple sensor device (SenseWear Armband) worn for at least 6 days. Physical activity duration (PAD; in minutes) for non-sedentary activities and physical activity level (PAL = total daily energy/resting energy expend…
The Impact of Body Mass Index on Disease Progression in Ankylosing Spondylitis
2018
Abstract Obesity can be a factor that affects the course of chronic systemic inflammatory arthritis. The objective of this study was to characterise patients with ankylosing spondylitis (AS) according to an evaluation of their body mass index (BMI) and by exploring the link between the overweightness and obesity with routinely measured disease-specific variables, including disease activity (Bath Ankylosing Spondylitis Disease Activity Index BASDAI; Ankylosing Spondylitis Disease Activity Score, using CRP, ASDAScrp), spinal mobility (Bath Ankylosing Spondylitis Metrology Index, BASMI), functional capacity (BASFI), extraspinal manifestations like fatigue, uveitis, and peripheral arthritis pre…

Return to Sports and Recreational Activity After Single-Stage Bilateral Short-Stem Total Hip Arthroplasty: 5-Year Results of a Prospective Observatio…
2019
Background:Single-stage bilateral total hip arthroplasty (THA) is an alternative to staged unilateral THA in patients suffering from bilateral hip arthritis; however, there is still broad concern regarding the safety and reliability of this procedure. Short-stem THA has emerged in recent years. To date, no data are available on sports and recreational activity levels after single-stage bilateral short-stem THA in the general patient population.Hypothesis:Patients who have undergone single-stage bilateral short-stem THA return to a satisfying level of sports and recreational activity at midterm follow-up.Study Design:Case series; Level of evidence, 4.Methods:A total of 54 consecutive patient…
