Relation between muscle mass, motor units and type of training in master athletes.
2014
OBJECTIVE: The aim of this study was to measure the number of motor units and muscle mass in power-trained and endurance-trained master athletes compared with community-dwelling older adults. METHODS: Seventy-five master athletes (52 power- and 23 endurance-trained athletes) were recruited at the 2012 European Veteran Athletics Championships in Zittau (Germany). One hundred and forty-nine community-dwelling older adults served as controls. In all participants, the motor unit number index (MUNIX) in the hypothenar muscle and whole body muscle mass was determined by bioelectrical impedance analysis (BIA). RESULTS: In both male and female master athletes, there were significant negative correl…
Long-term outcomes of patients with cerebral vein thrombosis: a multicenter study.
2012
Summary. Background: Little information is available on the long-term clinical outcome of cerebral vein thrombosis (CVT). Objectives and methods: In an international, retrospective cohort study, we assessed the long-term rates of mortality, residual disability and recurrent venous thromboembolism (VTE) in a cohort of patients with a first CVT episode. Results: Seven hundred and six patients (73.7% females) with CVT were included. Patients were followed for a total of 3171 patient-years. Median follow-up was 40 months (range 6, 297 months). At the end of follow-up, 20 patients had died (2.8%). The outcome was generally good: 89.1% of patients had a complete recovery (modified Rankin Scor…
Inability of HDL from abdominally obese subjects to counteract the inhibitory effect of oxidized LDL on vasorelaxation.
2007
Abdominal obesity is associated with a decreased plasma concentration of HDL cholesterol and with qualitative modifications of HDL, such as triglyceride enrichment. Our aim was to determine, in isolated aorta rings, whether HDL from obese subjects can counteract the inhibitory effect of oxidized low density lipoprotein (OxLDL) on endothelium-dependent vasodilation as efficiently as HDL from normolipidemic, lean subjects. Plasma triglycerides were 74% higher (P < 0.005) in obese subjects compared with controls, and apolipoprotein A-I (apoA-I) and HDL cholesterol concentrations were 12% and 17% lower (P < 0.05), respectively. HDL from control subjects significantly reduced the inhibitory effe…
Acute effects of coffee on QT interval in healthy subjects
2011
Abstract The coronary endothelial function is recognized to have an important role in the physiology of the diastolic ventricular relaxation, a phase of the heart cycle that influences the electrocardiographic QT interval. Endothelial function is investigated in vivo by flow mediated dilation (FMD) in the brachial artery and has proven to be a strong predictor of both coronary endothelial function and cardiovascular events. It has been reported that coffee acutely induces FMD changes. In particular, the brachial artery FMD seems to decrease after caffeinated coffee (CC) and to increase after decaffeinated coffee (DC) ingestion. Since the cardiovascular effects of coffee are still a debated …
Reliability of the Dynamic Gait Index (Finnish version) in individuals with neurological disorders
2012
To produce a Finnish version of the Dynamic Gait Index (DGI) and establish its reliability in people with neurological disorders affecting balance.A consecutive sample of 33 participants in inter-rater and 30 participants in intra-rater sample were tested. The DGI was administered in two testing sessions 1-2 h apart. Reliability was assessed with the intra-class correlation coefficient (ICC), Bland-Altman 95% limits of agreement, coefficient of reproducibility (CR), and standard error of the mean (SEM).The instructions from the original DGI were preserved during the translation process with no need for cultural adaptations. The relative reliability of the total scores proved to be high in i…
Reproducibility of Regional DEXA Examinations of Abdominal Fat and Lean Tissue
2013
<b><i>Objective: </i></b>The aim of this study was to develop and test the validity of a new repeatable method to delimit abdominal areas for follow-up of fat mass (FM) and lean tissue mass (LM) in DEXA examinations<i>. </i><b><i>Methods: </i></b>37 male volunteers underwent two DEXA examinations. Total body FM and LM measurements and corresponding abdominal measurements in a carefully defined region were calculated from the first scan. After repositioning of the subjects and a second scan, the delimited region was copied and the abdominal tissues re-calculated. <b><i>Results: </i></b>The mean LM of the abdo…
A Narrative Review about Nutritional Management and Prevention of Oral Mucositis in Haematology and Oncology Cancer Patients Undergoing Antineoplasti…
2021
Cancer is a prevalent disease worldwide, and treatments such as radiotherapy and chemotherapy sometimes lead to adverse events. Oral mucositis is one of the most disabling adverse events, and clinical guidelines do not take into account nutritional interventions. The primary endpoint was to gather the evidence about the efficacy of nutritional interventions in the prevention and/or treatment of antineoplastic-induced oral mucositis in oncological patients. A bibliographic review was carried out in the PubMed data base by combining MeSH terms with Boolean operators. Articles were selected based on inclusion and exclusion criteria; 50 final articles were found. Although further evidence is ne…
EMG and force production of the flexor hallucis longus muscle in isometric plantarflexion and the push-off phase of walking
2015
Large forces are generated under the big toe in the push-off phase of walking. The largest flexor muscle of the big toe is the flexor hallucis longus (FHL), which likely contributes substantially to these forces. This study examined FHL function at different levels of isometric plantarflexion torque and in the push-off phase at different speeds of walking. FHL and calf muscle activity were measured with surface EMG and plantar pressure was recorded with pressure insoles. FHL activity was compared to the activity of the calf muscles. Force and impulse values were calculated under the big toe, and were compared to the entire pressed area of the insole to determine the relative contribution of…
Changes in Health Utility, Disability, and Health-Related Quality of Life in Patients After Spinal Fusion
2014
STUDY DESIGN Prospective longitudinal database study. OBJECTIVE To evaluate changes in health utility, disability, and health-related quality of life (HRQOL) in patients undergoing spinal fusion. SUMMARY OF BACKGROUND DATA Recently, measuring disability, HRQOL, and health utility has become important when defining the value of surgical interventions. METHODS Data of spinal fusion patients from a prospective longitudinal database were analyzed. Health utility was captured by SF-6D (six dimensional health state classification from the 36-dimensional Short Form Health Survey) score, disability by Oswestry Disability Index, and HRQOL by the 36-Item Short Form Health Survey. The changes in these…
Although unseen, chronic pain is real–A phenomenological study
2013
Abstract Background Research has emphasised the essential role of psychosocial risk factors in chronic pain. In practice, pain is usually verified by identifying its physical cause. In patients without any distinct pathology, pain is easily defined as imaginary pain. The aim of this qualitative study was to explore the invisibility of chronic pain, from the patients’ perspective. Methods Thirty-four participants with chronic pain were interviewed. The mean age of the participants was 48 years, and 19 of them were women. For 21 of the participants, the duration of pain was more than five years, and most of the participants had degenerative spinal pain. The transcribed interviews were analyse…
