Benefits of smart pumps for automated changeovers of vasoactive drug infusion pumps: a quasi-experimental study.

Background: Manual changeover of vasoactive drug infusion pumps (CVIP) frequently lead to haemodynamic instability. Some of the newest smart pumps allow automated CVIP. The aim of this study was to compare automated CVIP with manual 'Quick Change' relays.

Cross-sectional study of pain and disability at knee replacement surgery for osteoarthritis in 299 patients.

Objective: To evaluate pain and disability at the time of knee replacement surgery for osteoarthritis.

Methods: In this multicenter cross-sectional study, 299 patients at 12 orthopedic surgery centers in Lyon, France were evaluated on the day before knee replacement surgery. Pain severity was assessed on a visual analog scale (VAS) and function using the Lequesne index and the Western Ontario McMaster Universities Osteoarthritis Index (WOMAC).

Selection of knee radiographs for trials of structure-modifying drugs in patients with knee osteoarthritis: a prospective, longitudinal study of Lyon Schuss knee radiographs with the definition of adequate alignment of the medial tibial plateau.

Objective: The quality of medial tibial plateau (MTP) alignment, which is assessed by measuring the distance between the anterior and posterior margins (intermargin distance [IMD]) of the tibial plateau, and the reproducibility of alignment in serial radiographs are suggested to be key elements in determining the accuracy and sensitivity to change in knee radiographs in patients with tibiofemoral osteoarthritis (OA). We evaluated the influence of both MTP alignment and radiograph superimposition on the sensitivity to change in radiographic joint space narrowing (JSN) in knee OA.

Methods: The study group comprised 106 patients with knee pain (73 with OA).

Influence of the quality of tibial plateau alignment on the reproducibility of computer joint space measurement from Lyon schuss radiographic views of the knee in patients with knee osteoarthritis.

Rationale: The quality of medial tibial plateau (MT-Plateau) alignment is one of the key elements for accuracy and sensitivity to change of knee radiography in knee osteoarthritis (OA).

Aim: To evaluate the influence of the quality of the MT-Plateau alignment on the reproducibility of joint space width (JSW) measurement in knee radiographs.

Methods: One hundred and twenty-seven knee radiographs (99 OA), performed using a standardized radiographic procedure (Lyon schuss (LS) view).
