mild, but not severe, valgus knee deformity. Ideal postoperative rotational kinematics may be different between the two groups and the difference may be taken into consideration in implant selections and surgical techniques.

Rotating hinge implants are commonly used in revision total knee arthroplasty (TKA) in the setting of significant ligamentous instability or bone deficiency. These highly constrained implants have been associated with variable clinical outcomes and uncertain long-term survivorship. The aim of this study is to establish long-term functional outcomes, radiographic results, and survivorship after revision TKA with a rotating hinge implant.

This is a retrospective study of prospectively collected data of 41 consecutive patients undergoing revision TKA with rotating hinge components and minimum 10-years follow-up. The study included 22 females (53.7%) and 19 males (46.3%) with a mean age of 66.6±8.5years. Clinical outcomes recorded included the Oxford Knee Score (OKS) preoperatively and at latest follow-up. Range of motion, implant survivorship, and complications were also recorded. Predefined radiological outcomes were obtained using plain radiographs.

There was a significant improvement in OKS after revision TKA with a rotating hinge implant compared to preoperative scores (40.7±4.2 vs. 21.4±4.9 respectively, p<0.001). At latest follow-up, mean range of motion was 111.5° ± 9.3° and mean overall limb alignment was 0.2° ± 2.0° varus. Implant survivorship at minimum 10-year follow-up was 90.2%. Radiographic lucent lines were observed in 14 patients (34.1%).

Revision TKA with a rotating hinge implant leads to satisfactory clinical outcomes and very good implant survivorship at long-term follow-up. Surgeons should have a low threshold to use these versatile implants in complex revision knee arthroplasty.

Unicompartmental osteoarthrosis increasingly affects younger patients who have high expectations concerning their postoperative level of activity. However, there is no available data on the activity level after fixed-bearing lateral unicompartmentalkneearthroplasty (UKA). The aim of this study was to report sports activity after fixed-bearing lateral UKA with a minimum two-year follow up.

Nineteen patients were surveyed to determine their sporting activities at a mean follow up of 4.6years (range 2.0-9.7years) after fixed-bearing lateral UKA. We also assessed the Knee Injury and Osteoarthritis Outcome Score Joint Replacement (KOOS JR) Score and the University of California, Los Angeles activity scale (UCLA scale) at baseline and latest follow up.

Before the onset of the first symptoms, 15 of 19 patients were active in at least one sport compared with 13 of 19 patients after surgery. Eighty-six per cent of the patients returned to activity. Within 6months, 68% returned to their activities after surgery. ated in sports less frequently compared with preoperative levels.

The pathogenesis of inflammatory bowel diseases (IBD), including Crohn's disease (CD) and ulcerative colitis (UC) has not been fully elucidated. Deucravacitinib solubility dmso However, a strong correlation between IBD and high T helper 17 (Th17) levels has been found. Sirtuin 2 (SIRT2) has recently been found to play an important role in metabolic reprogramming, but its potential anti-inflammatory properties remain unclear.

The expression levels of SIRT2 and glucose metabolism-related proteins in peripheral blood mononuclear cells (PBMCs) of IBD patients and healthy volunteers were detected. Human PBMCs were differentiated into Th17 cells in vitro and were treated with TM simultaneously. The ratio of Th17 cells and apoptotic cells and the production of Interleukin (IL)-17A and the expression levels of transcription factors of classical signaling pathway related to Th17 differentiation were determined. The acetylation of LDHA and glucose metabolism was assessed. Subsequently, C57BL/6J colitis mice induced by 2.5% dextran sulfatesodiumsay be a potential target for IBD treatment.

There is still no specific treatment strategies for COVID-19 other than supportive management.

A prospective case-control study determined by admittance to the hospital based on bed availability.

Eighteen patients with COVID-19 infection (laboratory confirmed) severe pneumonia admitted to hospital between 20th March and 19th April 2020. Patients admitted to the hospital during the study period were assigned to different beds based on bed availability. Depending on the bed the patient was admitted, the treatment was ozone autohemotherapy or standard treatment. Patients in the case group received ozonated blood twice daily starting on the day of admission for a median of four days. Each treatment involved administration of 200mL autologous whole blood enriched with 200mL of oxygen-ozone mixture with a 40μg/mL ozone concentration.

The primary outcome was time from hospital admission to clinical improvement.

Nine patients (50%) received ozonated autohemotherapy beginning on the day of admission. Ozonated autohemotherapy was associated with shorter time to clinical improvement (median [IQR]), 7days [6-10] vs 28days [8-31], p=0.04) and better outcomes at 14-days (88.8% vs 33.3%, p=0.01). In risk-adjusted analyses, ozonated autohemotherapy was associated with a shorter mean time to clinical improvement (-11.3days, p=0.04, 95% CI -22.25 to -0.42).

Ozonated autohemotherapy was associated with a significantly shorter time to clinical improvement in this prospective case-control study. Given the small sample size and study design, these results require evaluation in larger randomized controlled trials.

NCT04444531.To better understand humoral immunity following SARS-CoV-2 infection, 114 hospitalised COVID-19 patients with antibody monitored over 8 weeks from symptom onset were retrospectively investigated. A total of 445 serum samples were assessed via chemiluminescence immunoassay. Positive rate of virus-specific IgM reached up to over 80% from the second week to the eighth week after symptom onset, then declined quickly to below 30% in the twelfth week. Concentrations of IgG remained high for at least 3 months before subsequently declining. As compared with the non-severe group, serum IgM level from week 3 to week 8 was significantly higher among the patients with severe clinical symptoms (P = 0.012) but not IgG (P = 0.053). Serum IgM level from week 3 to week 8 was correlated with positive virus RNA test (r = 0.201, P = 0.044), albumin level (r = -0.295, P = 0.003), lactic dehydrogenase (LDH) level (r = 0.292, P = 0.003), alkaline phosphatase (ALP) level (r = 0.254, P = 0.010), C-reactive protein (CRP) level (r = 0.
