For centuries, the general consensus has been that vigorous, competitive exercise was harmful and shortened life expectancy. Recent data from prospective cohort studies conducted on marathon runners, professional cyclists, and Olympic athletes indicate, however, that regular intense endurance-exercise training has protective benefits against cardiovascular disease and premature death. There are still important questions to be answered, such as what is the optimal dose, in terms of both duration and intensity of training or competition, beyond which the health benefits of regular exercise stabilize or might even potentially disappear.

McArdle disease, caused by inherited deficiency of the enzyme muscle glycogen phosphorylase (GP-MM), is arguably the paradigm of exercise intolerance. The recent knock-in (p.R50X/p.R50X) mouse disease model allows an investigation of the phenotypic consequences of muscle glycogen unavailability and the physiopathology of exercise intolerance. We analysed, in 2-month-old mice [wild-type (wt/wt), heterozygous (p.R50X/wt) and p.R50X/p.R50X)], maximal endurance exercise capacity and the molecular consequences of an absence of GP-MM in the main glycogen metabolism regulatory enzymes: glycogen synthase, glycogen branching enzyme and glycogen debranching enzyme, as well as glycogen content in slow-twitch (soleus), intermediate (gastrocnemius) and glycolytic/fast-twitch (extensor digitorum longus; EDL) muscles.

Background Data on the cardiac characteristics of centenarians are scarce. Our aim was to describe electrocardiogram (ECG) and echocardiography in a cohort of centenarians and to correlate them with clinical data. Methods We used prospective multicenter registry of 118 centenarians (28 men) with a mean age of 101.5 ± 1.7 years. Electrocardiogram was performed in 103 subjects (87.3%) and echocardiography in 100 (84.7%). All subjects underwent a follow-up for at least 6 months. Results Centenarians with abnormal ECG were less frequently females (72% vs 93%), had higher rates of previous consumption of tobacco (14% vs 0) and alcohol (24% vs 12%), and scored lower in the perception of health status (6.8 ± 2.0 vs 8.3 ± 6.8). Centenarians with significant abnormalities in echocardiography were less frequently able to walk 6 m (33% vs 54%). Atrial fibrillation/flutter was found in 27 subjects (26%). Mean left ventricular (LV) ejection fraction was 60.0 ± 10.5%. Moderate or severe aortic valve stenosis was found in 16%, mitral valve regurgitation in 15%, and aortic valve regurgitation in 13%. Diastolic dysfunction was assessed in 79 subjects and was present in 55 (69.6%). Katz index and LV dilation were independently associated with the ability to walk 6 m. Age...

Background The benefit from intervention in elderly patients with symptomatic severe aortic stenosis (AS) and high comorbidity is unknown. Our aims were to establish the correlation between the Charlson comorbidity index and the prognosis of octogenarians with symptomatic sever AS and to identify patients who might not benefit from intervention. Methods We used the data from PEGASO (Pronóstico de la Estenosis Grave Aórtica Sintomática del Octogenario — Prognosis of symptomatic severe aortic stenosis in octogenarians), a prospective registry that included consecutively 928 patients aged ≥ 80 years with severe symptomatic AS. Results The mean Charlson comorbidity index was 3.0 ± 1.7, a total of 151 patients (16.3%) presented high comorbidity (index ≥ 5). Median survival was lower for patients with high comorbidity than for those without (16.7 ± 1.2 vs. 26.5 ± 0.6 months, p < 0.001). In patients without high comorbidity planned interventional management was clearly associated with prognosis (log rank p < 0.001), which was not the case in patients with high comorbidity (log rank p > 0.10). In multivariate analysis, the only variables that were independently associated with prognosis were planned medical management and Charlson index. Patients with high comorbidity presented non-cardiac death more frequently than those who had not (28.6% vs. 19.5%...

The results of studies on the association between sex mismatch and survival after heart transplantation are conflicting. Data from the Spanish Heart Transplantation Registry. From 4625 recipients, 3707 (80%) were men. The donor was female in 943 male recipients (25%) and male in 481 female recipients (52%). Recipients of male hearts had a higher body mass index (25.9 ± 4.1 vs. 24.3 ± 3.7; P < 0.01), and male donors were younger than female donors (33.4 ± 12.7 vs. 38.2 ± 12.3; P < 0.01). No further relevant differences related to donor sex were detected. In the univariate analysis, mismatch was associated with mortality in men (hazard ratio [HR], 1.18; 95% confidence interval [CI], 1.06–1.32; P = 0.003) but not in women (HR, 0.91; 95% CI 0.74–1.12; P = 0.4). A significant interaction was detected between sex mismatch and recipient gender (P = 0.02). In the multivariate analysis, sex mismatch was associated with long-term mortality (HR, 1.14; 95% CI 1.01–1.29; P = 0.04), and there was a tendency toward significance for the interaction between sex mismatch and recipient gender (P = 0.08). In male recipients, mismatch increased mortality mainly during the first month and in patients with pulmonary gradient >13 mmHg. Sex mismatch seems to be associated with mortality after heart transplantation in men but not in women.

Background Computed tomography (CT) findings can be used to classify invasive pulmonary aspergillosis (IPA) in 2 patterns: airway-invasive (AIR) or angioinvasive (ANG). Methods AIR-IPA was considered when the CT revealed peribronchial consolidation or a tree-in-bud pattern and ANG-IPA when a nodule, cavity, halo sign, infarct-shaped, or mass-like consolidation was found. We evaluated the correlation among IPA patterns on CT and outcomes in heart transplant (HT) recipients. Results The study included 27 HT recipients with a CT scan performed at the time of IPA diagnosis. The study interval was from 1988 to 2011. Ten AIR-IPA patients (37.1%) were compared with 17 ANG-IPA patients (62.9%). During the post-transplantation period before IPA developed, AIR patients required hemodialysis more frequently (40% vs 5.9%, p = 0.04). AIR patients also had more intercurrent bacterial pneumonia (23.5% vs 70%, p < 0.001), and IPA was diagnosed later after onset of symptoms (2.7 vs 8.5 d, p = 0.09). After diagnosis, AIR-IPA patients required more mechanical ventilation (23.5% vs 90%, p < 0.01) and had a higher related mortality rate (23.5% vs 70%, p = 0.04). Conclusions Our study shows that the AIR pattern represents 37% of IPA episodes in HT recipients and is associated with a more protracted clinical presentation...

Aims Surgery for infective endocarditis (IE) is associated with high mortality. Our objectives were to describe the experience with surgical treatment for IE in Spain, and to identify predictors of in-hospital mortality. Methods Prospective cohort of 1000 consecutive patients with IE. Data were collected in 26 Spanish hospitals. Results Surgery was performed in 437 patients (43.7%). Patients treated with surgery were younger and predominantly male. They presented fewer comorbid conditions and more often had negative blood cultures and heart failure. In-hospital mortality after surgery was lower than in the medical therapy group (24.3 vs 30.7%, p = 0.02). In patients treated with surgery, endocarditis involved a native valve in 267 patients (61.1%), a prosthetic valve in 122 (27.9%), and a pacemaker lead with no clear further valve involvement in 48 (11.0%). The most common aetiologies were Staphylococcus (186, 42.6%), Streptococcus (97, 22.2%), and Enterococcus (49, 11.2%). The main indications for surgery were heart failure and severe valve regurgitation. A risk score for in-hospital mortality was developed using 7 prognostic variables with a similar predictive value (OR between 1.7 and 2.3): PALSUSE: prosthetic valve, age ≥ 70...

In the present work homogeneous mullite and mullite–alumina composites reinforced with carbon nanofibers (CNFs) were prepared. The stability of aqueous mullite and mullite–CNFs suspensions was studied through zeta potential and rheological behaviour of concentrated slurries. Slurries were optimised in terms of dispersant concentration and solids content and further used for the preparation of homogeneous mixtures of powders by freeze drying. The obtained powders were characterised through the determination of particle size distribution and morphology by Field Emission Scanning Electron Microscopy (FSEM) and Laser Scattering. The freeze dried powders were used to obtain dense composites by spark plasma sintering. Their microstructure and mechanical properties were evaluated.

ENG
McArdle disease, also termed ‘glycogen storage disease type V’, is a disorder of skeletal muscle carbohydrate metabolism caused by inherited deficiency of the muscle-specific isoform of glycogen phosphorylase (GP-MM). It is an autosomic recessive disorder that is caused by mutations in the PYGM gene and typically presents with exercise intolerance, i.e. episodes of early exertional fatigue frequently accompanied by rhabdomyolysis and myoglobinuria. Muscle biopsies from affected individuals contain subsarcolemmal deposits of glycogen. Besides GP-MM, two other GP isoforms have been described: the liver (GP-LL) and brain (GP-BB) isoforms, which are encoded by the PYGL and PYGB genes, respectively; GP-BB is the main GP isoform found in human and rat foetal tissues, including the muscle, although its postnatal expression is dramatically reduced in the vast majority of differentiated tissues with the exception of brain and heart, where it remains as the major isoform. We developed a cell culture model from knock-in McArdle mice that mimics the glycogen accumulation and GP-MM deficiency observed in skeletal muscle from individuals with McArdle disease. We treated mouse primary skeletal muscle cultures in vitro with sodium valproate (VPA)...

Patients suffering from glycogen storage disease V (McArdle disease) were shown to have higher surface electrical activity in their skeletal muscles when exercising at the same intensity as their healthy counterparts, indicating more muscle fibre recruitment. To explain this phenomenon, this study investigated whether muscle fibre type is shifted towards a predominance in type I fibres as a consequence of the disease. Muscle biopsies from the Biceps brachii (BB) (n = 9) or Vastus lateralis (VL) (n = 8) were collected over a 13-year period from male and female patients diagnosed with McArdle disease, analysed for myosin heavy chain (MHC) isoform content using SDS-PAGE, and compared to healthy controls (BB: n = 3; VL: n = 10). All three isoforms were expressed and no difference in isoform expression in VL was found between the McArdle patients and healthy controls (MHC I: 33±19% vs. 43±7%; MHC IIa: 52±9% vs. 40±7%; MHC IIx: 15±18% vs. 17±9%).

Variations in tobacco-related cancers, incidence and prevalence reflect differences in tobacco consumption in addition to genetic factors. Besides, genes related to lung cancer risk could be related to smoking behavior. Polymorphisms altering DNA repair capacity may lead to synergistic effects with tobacco carcinogen-induced lung cancer risk. Common problems in genetic association studies, such as presence of gene-by-environment (G x E) correlation in the population, may reduce the validity of these designs. The main purpose of this study was to evaluate the independence assumption for selected SNPs and smoking behaviour in a cohort of 320 healthy Spanish smokers. We found an association between the wild type alleles of XRCC3 Thr241Met or KLC3 Lys751Gln and greater smoking intensity (OR = 12.98, 95% CI = 2.86-58.82 and OR=16.90, 95% CI=2.09-142.8; respectively). Although preliminary, the results of our study provide evidence that genetic variations in DNA-repair genes may influence both smoking habits and the development of lung cancer. Population-specific G x E studies should be carried out when genetic and environmental factors interact to cause the disease.

OBJECTIVES: The aim of this study was to examine the relationship between semicircular lipoatrophy (SL), inflammation marker (high sensibility C-reactive protein [hs-CRP]), adipokines (leptine, chemerine and vaspine) and autoimmune markers (rheumatoid factor [RF], C3 and C4 complement fractions, antinuclear antibodies [ANA], HLA DR3, and DR4). Chemerine is an adipokine, but also is an immunity marker. METHODS: A case-control study was performed in May 2013; 21 cases were included. The closest healthy coworker to each case was used as a control. We calculated Kruskal-Wallis nonparametric test. RESULTS: We found statistical significance (P<.05) between SL and raised hs-CRP, raised leptine and low chemerine. CONCLUSIONS: i) There seems to be an underlying inflammatory component (raised hs-CRP) in SL; ii) adipokine alteration (raised leptine and low chemerine) supports the idea that adipocytic differentiation is affected in SL, and iii) we have not found any immune marker associated with SL, except chemerine itself, which could explain a possible association between SL and immunity.

This pilot study is a single-blind, randomized, controlled clinical trial that included 20 participants, aged 65 years and older, who were diagnosed with nonspecific shoulder pain. The study was approved by the Clinical Research Ethics Committee of the area. Participants were recruited at their homes or at a care center and were randomly assigned into either an experimental group (n = 10), which received a session of DDN on 1 active and 1 latent MTrP of the infraspinatus muscle, or a control group (n = 10), which received a session of DDN on only 1 active MTrP. A blind examiner assessed the pain intensity, pain pressure threshold on the anterior deltoid, and extensor carpi radialis brevis muscles and grip strength before, immediately after, and 1 week after the intervention.

Severe symptomatic aortic stenosis is a serious condition of elderly, mostly geriatric patients with a poor prognosis if the valve is not replaced. Since geriatricians are able to provide major expertise in the prognostic assessment as well in the clinical management of these patients, they need to be more closely involved in the decision making process. For this reason the European Union Geriatric Medicine Society (EUGMS) represented by the authors phrased three propositions: (1) geriatricians need to be aware of the impact of severe aortic stenosis on patients’ outcomes and should be encouraged to take an active role in aortic stenosis management; (2) they need to be aware of treatment options and are required to support multidisciplinary teams with their expertise in assessing geriatric patients; (3) they should routinely perform a comprehensive geriatric assessment in patients with severe aortic stenosis scheduled to undergo surgical or transcatheter aortic valve replacement and during long-term follow-up.

Lower extremity (LE) exercise training has been shown to contribute to improvements in Maximum Walking Distance (MWD), Claudication Distance (CD), peak oxygen uptake (VO2peak) and Quality of Life (QoL) in patients with intermittent claudication (IC). However, little is known regarding the efficacy of upper extremity (UE) exercise training in comparison to the widely used LE training. The objective of this systematic literature review is to identify and synthesize the available literature on the effects of UE versus LE exercises using the International Classification of Functioning (ICF) conceptual framework. A total of 6 randomized controlled trials comparing UE to LE exercises were included in this study. Two of the articles were considered to be of high quality using the PEDro grading list. Both UE and LE training groups demonstrated significant improvements in MWD, CD, VO2peak and QoL in comparison to the control group but LE was not better than UE training. This supports the use of UE training as an alternative to LE, which could provide symptomatic relief to patients with IC without the discomfort caused during the LE training.

This study aimed to determine whether biomechanical characteristics such as ground-contact time, swing time, and stride length and frequency contribute to the exceptional running economy of East African runners. Seventeen elite long-distance runners (9 Eritrean, 8 European) performed an incremental maximal running test and 3 submaximal running bouts at 17, 19, and 21 km/h. During the tests, gas-exchange parameters were measured to determine maximal oxygen uptake (VO2max) and running economy (RE). In addition, ground-contact time, swing time, stride length, and stride frequency were measured.

Supplier selection management has been considered as an important subject for industrial organizations. In order to remain on the market, to gain profitability and to retain competitive advantage, business units need to establish an integrated and structured supplier selection system. In addition, environmental protection problems have been big solicitudes for organizations to consider green approach in supplier selection problem. However, finding proper suppliers involves several variables and it is critically a complex process. In this paper, the main attention is focused on finding the right supplier based on fuzzy multi criteria decision making (MCDM) process. The weights of criteria are calculated by analytical hierarchical process (AHP) and the final ranking is achieved by fuzzy technique for order preference by similarity to an ideal solution (TOPSIS). TOPSIS advantage among the other similar methods is to obtain the best solution close to ideal solution. The paper attempts to express better understanding by an example of an automobile manufacturing supply chain.

Due to the rapid development of microelectromechanical systems (MEMS) technology and large numbers of candidate materials, material selection for MEMS devices needs systematic approach. In this paper, for different applications of MEMS electrostatic actuators, based on the actuation voltage and force, speed of actuation and electrical resistivity, the most appropriate materials are selected. For this purpose, Ashby approach as Multi Objective Decision Making (MODM) technique, Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and VIse Kriterijumska Optimizacija kompromisno Resenja (VIKOR) methods as Multiple Attribute Decision Making (MADM) technique are used. The results show good agreement between these three different methods for material selection. The analysis suggest that for high actuation force and speed devices, diamond and Silicon Carbide are the best, for large displacement with low actuation voltage actuators, polymers such as Polymethyl methacrylate (PMMA) and Polyvinylidene fluoride (PVDF) are the best options. Also, for low electrical resistivity, high speed with low actuation voltage devices, aluminum is recommended. Finally, based on the results, comparison between Ashby, VIKOR and TOPSIS methods are presented.
