Impaired muscle Ca2+ and K+ regulation contribute to poor exercise performance post-lung transplantation.
Lung transplant recipients (LTx) exhibit marked peripheral limitations to exercise. We investigated whether skeletal muscle Ca2+ and K+ regulation might be abnormal in eight LTx and eight healthy controls. Peak oxygen consumption and arterialized venous plasma [K+] (where brackets denote concentration) were measured during incremental exercise. Vastus lateralis muscle was biopsied at rest and a...
متن کاملEffects of endurance training on extrarenal potassium regulation and exercise performance in patients on haemodialysis.
BACKGROUND Haemodialysis patients (HDP) with anaemia display impaired plasma K(+) regulation during exercise and poor exercise performance. Epoetin treatment and exercise training improve exercise performance in HDP, but whether this is associated with improved K(+) regulation is unknown. METHODS Six HDP with near-normal [Hb] were tested for aerobic power ( ) and plasma [K(+)] during incremen...
متن کاملLimiting factors of exercise performance 1 year after lung transplantation.
BACKGROUND After lung transplantation (LTx) exercise capacity frequently remains limited, despite significantly improved pulmonary function. The aim of this study was to evaluate maximal exercise capacity and peripheral muscle force before and 1 year after LTx, and to determine whether peripheral muscle force and lactate threshold (LT) limit exercise capacity 1 year after LTx. METHODS Twenty-...
متن کاملThe effects of exercise training on muscle atrophy in haemodialysis patients.
BACKGROUND Patients with end-stage renal disease on haemodialysis (HD) have limited work capacity. Many structural and functional alterations in skeletal muscles contribute to this disability. METHODS To evaluate the effects of exercise training on uraemic myopathy, seven HD patients (mean age 44.1+/-17.2 years) were studied. Open muscle biopsies were taken from their vastus lateralis muscle ...
متن کاملPost-Intubation Tracheoesophageal Fistula; A Nine-Year Experience
Introduction: Tracheoesophageal fistula (TEF) is a rare condition, which could be life-threatening if diagnosed late or mismanaged. Post-intubation TEF is the most common form of acquired, non-malignant TEF and is usually associated with tracheal stenosis, which makes the treatment more challenging. Here, we present our experience of managing 21 patients with post-intubation TEF. Materials & ...
