Background: This article describes an updated stepwise algorithm for the pharmacological management of osteoarthritis (OA) to establish a treatment method for patients with OA., Summary: In step 1, background maintenance therapy includes symptomatic slow-acting drugs for OA, especially prescription crystalline glucosamine sulfate product, for which the high-quality evidence base of efficacy is unequivocal, or prescription chondroitin sulfate. Oral nonsteroidal anti-inflammatory drugs (NSAIDs) or paracetamol only as rescue analgesia is given on top of the background therapy. Step 2: For patients with persistent OA symptoms, the use of oral NSAIDs is mandatory for maintaining supportive therapy with symptomatic slow-acting drugs for OA. It is recommended to properly stratify patients and carefully select oral NSAID therapy to maximize the benefit-to-risk ratio. Intra-articular hyaluronic acid and intra-articular corticosteroids are recommended as well in step 2 of the algorithm, especially for patients who do not respond to the previous therapies. Step 3: Duloxetine is considered along with the previous procedures, especially in patients with pain from central sensitization. Step 4: Total joint replacement is recommended for patients with severe symptoms and poor quality of life., Major Conclusions: The current guidelines and literature review provide evidence-based recommendations supported by clinical experience on how to organize the treatment process in patients with knee OA applicable in the Russian clinical practice., Future Research Directions: International evidence-based guidelines lack consensus on different treatments, including the use of prescription crystalline glucosamine sulfate, NSAIDs, and intra-articular hyaluronic acid. The content of this article needs a further discussion about the clinical evidence and harmonization of recommendations for knee OA management., Competing Interests: The authors declare no conflict of interest., (Copyright © 2020 Wolters Kluwer Health, Inc.

Objective: Acute kidney injury (AKI) occurs frequently after cardiac surgery. Levosimendan might reduce the incidence of AKI in patients undergoing cardiac surgery. The authors investigated whether levosimendan administration could reduce AKI incidence in a high-risk cardiac surgical population., Design: Post hoc analysis of a multicenter randomized trial., Setting: Cardiac surgery operating rooms and intensive care units of 14 centers in 3 countries., Participants: The study comprised 90 patients who underwent mitral valve surgery with an estimated glomerular filtration rate <60 mL/min/1.73 m 2 and perioperative myocardial dysfunction., Interventions: Patients were assigned randomly to receive levosimendan (0.025-0.2 μg/kg/min) or placebo in addition to standard inotropic treatment., Measurements and Main Results: Forty-six patients were assigned to receive levosimendan and 44 to receive placebo. Postoperative AKI occurred in 14 (30%) patients in the levosimendan group versus 23 (52%) in the placebo group (absolute difference -21.8; 95% confidence interval -41.7 to -1.97; p = 0.035). The incidence of major complications also was lower (18 [39%]) in the levosimendan group versus that in the placebo group (29 [66%]) (absolute difference -26.8 [-46.7 to -6.90]; p = 0.011). A trend toward lower serum creatinine at intensive care unit discharge was observed in the levosimendan group (1.18 [0.99-1.49] mg/dL) versus that in the placebo group (1.39 [1.05-1.76] mg/dL) (95% confidence interval -0.23 [-0.49 to 0.01]; p = 0.07)., Conclusions: Levosimendan may improve renal outcome in cardiac surgery patients with chronic kidney disease undergoing mitral valve surgery who develop perioperative myocardial dysfunction. Results of this exploratory analysis should be investigated in future properly designed randomized controlled trials., (Copyright © 2018 Elsevier Inc. All rights reserved.)
