RATIONALE Diaphragmatic function is a major determinant of the ability to successfully wean patients from mechanical ventilation (MV). Paradoxically, MV itself results in a rapid loss of diaphragmatic strength in animals. However, very little is known about the time course or mechanistic basis for such a phenomenon in humans. OBJECTIVES To determine in a(More)
BACKGROUND Skeletal muscle failure and wasting are manifestations of sepsis in humans that leads to serious and prolonged complications. The authors investigated the role of the major proinflammatory and antiinflammatory pathways, namely the inducible isoforms cyclooxygenase (COX-2) and heme oxygenase (HO-1), and the ubiquitin proteolytic pathway in(More)
INTRODUCTION Cardiac troponin has been shown to be elevated in one-half of the parturients admitted for post-partum haemorrhage. The purpose of the study was to assess whether increased cardiac troponin was associated with a simultaneous alteration in haemoglobin tissue oxygen saturation in peripheral muscles in post-partum haemorrhage. METHODS Tissue(More)
OBJECTIVE Mechanisms of sepsis-induced myocardial and diaphragmatic alteration are multiple and remain largely unknown, particularly in humans. In the present study, we compared the inducible nitric oxide synthase (NOS-2) expression, the peroxynitrite production and the expression and activation of the ubiquitin proteolytic pathway in the wall of the 4(More)
BACKGROUND Despite the development of multimodal analgesia for postoperative pain management, opioids are still required for effective pain relief after knee arthroplasty. We aimed to identify the determinants of post-operative pain intensity and post-operative opioid requirement in this context. METHODS In this observational prospective study, we(More)
