The use of dietary supplements is widespread among athletes in all sports and at all levels of competition, as it is in the general population. For the athlete training at the limits of what is sustainable, or for those seeking a shortcut to achieving their aims, supplements offer the prospect of bridging the gap between success and failure. Surveys show, however, that this is often not an informed choice and that the knowledge level among consumers is often low and that they are often influenced in their decisions by individuals with an equally inadequate understanding of the issues at stake...

BACKGROUND: Levosimendan is a calcium sensitizer drug causing increased contractility in the myocardium and vasodilation in the vascular system. It is mainly used for the therapy of acute decompensated heart failure. Several studies on animals and humans provided evidence of the cardioprotective properties of levosimendan including preconditioning and anti-apoptotic. In view of these favorable effects, levosimendan has been tested in patients undergoing cardiac surgery for the prevention or treatment of low cardiac output syndrome...

The present study investigated the effects of different intensities of resistance training (RT) on elbow flexion and leg press one-repetition maximum (1RM) and muscle cross-sectional area (CSA). Thirty men volunteered to participate in an RT programme, performed twice a week for 12 weeks. The study employed a within-subject design, in which one leg and arm trained at 20% 1RM (G20) and the contralateral limb was randomly assigned to one of the three conditions: 40% (G40); 60% (G60), and 80% 1RM (G80). The G20 started RT session with three sets to failure...

Chronic heart failure is a progressive disease with an increasing prevalence. In spite of all medical progress (or thanks to it), it is finally one of the most common causes of death. Palliative care is an approach aimed to improve the quality of life of patients and their families in cases of life-threatening illness. Therefore, the use of palliative care in cardiology is entirely relevant. Estimating the course and prognosis of a patient with chronic heart failure is difficult despite many prognostic tools...

Simultaneous pancreas-kidney (SPK) transplantation is the primary surgical treatment for type I diabetes mellitus with end-stage renal disease. However, this transplant surgery has a high-risk of surgical complications, including duodenal anastomotic leakage, which may lead to pancreas transplantation failure if the leakage worsens. This case report describes a patient who suffered from duodenal anastomotic leakage after SPK transplantation. The digestive enzymes eroded the wound and skin around the wound, resulting in periwound moisture-associated dermatitis...

The discovery of a new class of massive chromosomal rearrangement, baptized chromothripsis, in different cancers and congenital disorders has deeply modified our understanding on the genesis of complex genomic rearrangements. Several mechanisms, involving abortive apoptosis, telomere erosion, mitotic errors, micronuclei formation, and p53 inactivation, might cause chromothripsis. The remarkable point is that all these plausible mechanisms have been identified in the field of human reproduction as causal factors for reproductive failures and chromosomal abnormality genesis...

BACKGROUND: The majority of critically ill patients do not suffer from acute respiratory distress syndrome (ARDS). To improve the treatment of these patients, we aimed to identify potentially modifiable factors associated with outcome of these patients. METHODS: The PRoVENT was an international, multicenter, prospective cohort study of consecutive patients under invasive mechanical ventilatory support. A predefined secondary analysis was to examine factors associated with mortality...

BACKGROUND: Interactions between thiopurines and infliximab presumably contribute to superior effect of infliximab-thiopurine combination therapy in patients with inflammatory bowel disease (IBD). We examined whether principal cytotoxic thiopurine metabolites influence adalimumab (ADL) and anti-ADL antibodies (Abs). METHODS: Ninety-eight IBD patients previously treated with infliximab (96%) in whom trough ADL and anti-ADL Abs had been assessed as part of their clinical care were included...

Heart failure (HF) is one of the leading causes of hospitalization and readmissions. Our study aimed to examine racial disparities in heart failure patients including onset, mortality, length of stay (LOS), direct costs, and readmission rates. This is a secondary data analysis. We analyzed the risk-adjusted inpatient data of all patients admitted with HF to one health academic center. We compared five health outcomes among three racial groups (white, black, and Hispanic). There were 1006 adult patients making 1605 visits from 10/01/2011 to 09/30/2015...

While in adults major advances in heart failure therapy in patients with dilated cardiomyopathy were documented in the last two decades, research on the mechanism and therapies of heart failure in children with left ventricular dilated cardiomyopathy has lagged behind. Despite the lack of sufficient randomized prospective studies, ACE inhibitors are first line and ß-receptor antagonists are second-line strategies in children. Following the adult guidelines, without having data concerning the pediatric population, mineral corticoids are also accepted in the treatment of pediatric heart failure, while diuretics should only be used to achieve a euvolemic status...

Previous studies have suggested the involvement of CD4 + T lymphocytes in cardiac remodelling. T-bet can direct Th1 lineage commitment. This study aimed to investigate the functional significance of T-bet in cardiac remodelling induced by pressure overload using T-bet global knockout rats. Increased T-bet levels were observed in rodent and human hypertrophied hearts. T-bet deficiency resulted in a less severe hypertrophic phenotype in rats. CD4 + T-lymphocyte reconstitution in T-bet-/- rats resulted in aggravated cardiac remodelling...

PURPOSE: Although the posterolateral approach for hip arthroplasty is popular and has numerous advantages, it has been known to have a propensity for dislocation. The repair of short external rotator muscles with capsule is important for reducing dislocation. The purpose of this study is to investigate the incidence of suture failure, dislocation, and time to failure for two repair techniques for posterior soft tissue repair during total hip arthroplasty. METHODS: In this study of 167 total hip arthroplasties in 159 patients, we reattached the short external rotator tendon with posterior capsule to the greater trochanter transosseously (tendon-to-bone, 87 hips) or the gluteus medius tendon (tendon-to-tendon, 80 hips)...

We present the case of a 46-year-old woman who underwent revision surgery approximately 4 years after total hip arthroplasty because of a fracture of the modular neck of a MODULUS femoral stem. The fractured surfaces of the retrieved implant were inspected using optical and scanning electron microscopy. Three-dimensional finite element analysis was also performed to identify the stresses that might have caused the failure. We concluded that active, obese patients who are implanted with a high-offset, small-sized modular component could experience stress-induced fractures of the modular neck, with proper fixation and osseointegration of the distal stem, especially if residual bone or tissue is present on the inner surface of the neck that could contribute to micromovement and decreased proximal fixation...
