Abstract Background Post-operative pulmonary complications (PPC) can develop in up to 13% of patients undergoing neurosurgical procedures and may adversely affect clinical outcome. The use of intraoperative lung protective ventilation (LPV) strategies, usually including the use of a low Vt, low PEEP and low plateau pressure, seem to reduce the risk of PPC and are strongly recommended in almost all surgical procedures. Nonetheless, feasibility of LPV strategies in neurosurgical patients are still debated because the use of low Vt during LPV might result in hypercapnia with detrimental effects on cerebrovascular physiology. Aim of our study was to determine whether LPV strategies would be feasible compared with a control group in adult patients undergoing cranial or spinal surgery. Methods This single-centre, pilot randomized clinical trial was conducted at the University Hospital “Maggiore della Carità” (Novara, Italy). Adult patients undergoing major cerebral or spinal neurosurgical interventions with risk index for pulmonary post-operative complications > 2 and not expected to need post-operative intensive care unit (ICU) admission were considered eligible. Patients were randomly assigned to either LPV (Vt = 6 ml/kg of ideal body weight (IBW), respiratory rate initially set at 16 breaths/min, PEEP at 5 cmH2O and application of a recruitment manoeuvre (RM) immediately after intubation and at every disconnection from the ventilator) or control treatment (Vt = 10 ml/kg of IBW, respiratory rate initially set at 6–8 breaths/min, no PEEP and no RM). Primary outcomes of the study were intraoperative adverse events, the level of cerebral tension at dura opening and the intraoperative control of PaCO2. Secondary outcomes were the rate of pulmonary and extrapulmonary complications, the number of unplanned ICU admissions, ICU and hospital lengths of stay and mortality. Results A total of 60 patients, 30 for each group, were randomized. During brain surgery, the number of episodes of intraoperative hypercapnia and grade of cerebral tension were similar between patients randomized to receive control or LPV strategies. No difference in the rate of intraoperative adverse events was found between groups. The rate of postoperative pulmonary and extrapulmonary complications and major clinical outcomes were similar between groups. Conclusions LPV strategies in patients undergoing major neurosurgical intervention are feasible. Larger clinical trials are needed to assess their role in postoperative clinical outcome improvements.

Cartilage Restoration

Background: There is currently no optimal method for cartilage restoration in large, full-thickness cartilage defects in older patients. Purpose: To determine whether implantation of a composite of allogeneic umbilical cord blood–derived mesenchymal stem cells and 4% hyaluronate (UCB-MSC-HA) will result in reliable cartilage restoration in patients with large, full-thickness cartilage defects and whether any clinical improvements can be maintained up to 5 years postoperatively. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: A randomized controlled phase 3 clinical trial was conducted for 48 weeks, and the participants then underwent extended 5-year observational follow-up. Enrolled were patients with large, full-thickness cartilage defects (International Cartilage Repair Society [ICRS] grade 4) in a single compartment of the knee joint, as confirmed by arthroscopy. The defect was treated either with UCB-MSC-HA implantation through mini-arthrotomy or with microfracture. The primary outcome was proportion of participants who improved by ≥1 grade on the ICRS Macroscopic Cartilage Repair Assessment (blinded evaluation) at 48-week arthroscopy. Secondary outcomes included histologic assessment; changes in pain visual analog scale (VAS) score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and International Knee Documentation Committee (IKDC) score from baseline; and adverse events. Results: Among 114 randomized participants (mean age, 55.9 years; 67% female; body mass index, 26.2 kg/m2), 89 completed the phase 3 clinical trial and 73 were enrolled in the 5-year follow-up study. The mean defect size was 4.9 cm2 in the UCB-MSC-HA group and 4.0 cm2 in the microfracture group ( P = .051). At 48 weeks, improvement by ≥1 ICRS grade was seen in 97.7% of the UCB-MSC-HA group versus 71.7% of the microfracture group ( P = .001); the overall histologic assessment score was also superior in the UCB-MSC-HA group ( P = .036). Improvement in VAS pain, WOMAC, and IKDC scores were not significantly different between the groups at 48 weeks, however the clinical results were significantly better in the UCB-MSC-HA group at 3- to 5-year follow-up ( P < .05). There were no differences between the groups in adverse events. Conclusion: In older patients with symptomatic, large, full-thickness cartilage defects with or without osteoarthritis, UCB-MSC-HA implantation resulted in improved cartilage grade at second-look arthroscopy and provided more improvement in pain and function up to 5 years compared with microfracture.

Background:Secukinumab was approved by NICE for patients with active Ankylosing Spondylitis and Psoriatic Arthritis in 2017. Clinical trial data suggests secukinumab is a useful treatment option in both conditions, but often real world experience differs greatly from clinical trial results. In addition, patients with more refractory disease are often excluded from clinical trials.Objectives:To assess the response to secukinumab in patients with seronegative spondyloarthropathy receiving treatment at University Hospital Coventry and WarwickshireMethods:Patients starting secukinumab at UHCW were identified from the Blueteq funding database. Medical notes were reviewed retrospectively to assess response rates using BASDAI responses in Ankylosing spondylitis and PsARC responses in PsA. Patients who had previously had inadequate response to TNF inhibitors (PsA only) and severe psoriasis received 300mg secukinumab monthly; the remainder were prescribed 150mg monthly.Results:146 patients commenced secukinumab between June 2017 and January 2020 and had outcome data recorded. 73 patients (50%) had received previous biologic agents prior to secukinumab exposure. Patients with Ankylosing spondylitis had high BASDAI (6.8±1.4) and spinal pain (7.5±1.4). 48 patients had an initial response to treatment as per outcome measures done before and after Secukinumab inception. Secukinumab was effective in 89 patients (94%), and 87 (91%) continued treatment.In psoriatic arthritis, despite high levels of activity at baseline (mean tender joint count 10±8; swollen joint count 6±3) and 65% prior biologic exposure; high rates of response were seen. The majority of patients have continued treatment. Secukinumab was well tolerated in both patient groups with low rates of discontinuation due to adverse events (8 patients, 5%). Adverse events included recurrent infection (3), rash (1), mouth ulcers (1), vertigo (1), new onset cancer (1) and new onset Crohn’s (1) although rates were low overall. Patients with pre-existing uveitis did not develop exacerbations but low numbers of patients with prior uveitis were treated.PsA (n=51)AS (n=95)Age in years, mean (SD)53 (13)49(12)Male sex, n (%)21 (41)62 (65)Disease duration in years, mean (SD)8 (8)10.9 (9.2)Previous biologic exposure, n (%)30 (65)43 (48)Number of prior biologics, median (range)1 (1-4)1 (1-4)Responder, n (%)37 (72)*89 (93)Discontinuation, n(%)12 (24)8 (8.5)Adverse events62Lack of efficacy64Other02*Response could not be assessed in 3/51 PsA patients due to insufficient clinical data; these patients have been recorded as non respondersConclusion:Secukinumab demonstrates high levels of efficacy even in a cohort of patients with longstanding PSA and AS with high rates of inadequate responses to other biologics.Secukinumab is well tolerated with low rates of discontinuation due to adverse events.References:Certolizumab pegol and secukinumab for treating active psoriatic arthritis after inadequate response to DMARDs Technology appraisal guidance [TA445]Secukinumab for active ankylosing spondylitis after treatment with non-steroidal anti-inflammatory drugs or TNF-alpha inhibitors Technology appraisal guidance [TA407]Disclosure of Interests:None declared
