RESUMO
BACKGROUND: Concomitant administration of COVID-19 and influenza vaccines could reduce burden on health-care systems. We aimed to assess the safety of concomitant administration of ChAdOx1 or BNT162b2 plus an age-appropriate influenza vaccine. METHODS: In this multicentre, randomised, controlled, phase 4 trial, adults in receipt of a single dose of ChAdOx1 or BNT162b2 were enrolled at 12 UK sites and randomly assigned (1:1) to receive concomitant administration of either an age-appropriate influenza vaccine or placebo alongside their second dose of COVID-19 vaccine. 3 weeks later the group who received placebo received the influenza vaccine, and vice versa. Participants were followed up for 6 weeks. The influenza vaccines were three seasonal, inactivated vaccines (trivalent, MF59C adjuvanted or a cellular or recombinant quadrivalent vaccine). Participants and investigators were masked to the allocation. The primary endpoint was one or more participant-reported solicited systemic reactions in the 7 days after first trial vaccination(s), with a difference of less than 25% considered non-inferior. Analyses were done on an intention-to-treat basis. Local and unsolicited systemic reactions and humoral responses were also assessed. The trial is registered with ISRCTN, ISRCTN14391248. FINDINGS: Between April 1 and June 26, 2021, 679 participants were recruited to one of six cohorts, as follows: 129 ChAdOx1 plus cellular quadrivalent influenza vaccine, 139 BNT162b2 plus cellular quadrivalent influenza vaccine, 146 ChAdOx1 plus MF59C adjuvanted, trivalent influenza vaccine, 79 BNT162b2 plus MF59C adjuvanted, trivalent influenza vaccine, 128 ChAdOx1 plus recombinant quadrivalent influenza vaccine, and 58 BNT162b2 plus recombinant quadrivalent influenza vaccine. 340 participants were assigned to concomitant administration of influenza and a second dose of COVID-19 vaccine at day 0 followed by placebo at day 21, and 339 participants were randomly assigned to concomitant administration of placebo and a second dose of COVID-19 vaccine at day 0 followed by influenza vaccine at day 21. Non-inferiority was indicated in four cohorts, as follows: ChAdOx1 plus cellular quadrivalent influenza vaccine (risk difference for influenza vaccine minus placebos -1·29%, 95% CI -14·7 to 12·1), BNT162b2 plus cellular quadrivalent influenza vaccine (6·17%, -6·27 to 18·6), BNT162b2 plus MF59C adjuvanted, trivalent influenza vaccine (-12·9%, -34·2 to 8·37), and ChAdOx1 plus recombinant quadrivalent influenza vaccine (2·53%, -13·3 to 18·3). In the other two cohorts, the upper limit of the 95% CI exceeded the 0·25 non-inferiority margin (ChAdOx1 plus MF59C adjuvanted, trivalent influenza vaccine 10·3%, -5·44 to 26·0; BNT162b2 plus recombinant quadrivalent influenza vaccine 6·75%, -11·8 to 25·3). Most systemic reactions to vaccination were mild or moderate. Rates of local and unsolicited systemic reactions were similar between the randomly assigned groups. One serious adverse event, hospitalisation with severe headache, was considered related to the trial intervention. Immune responses were not adversely affected. INTERPRETATION: Concomitant vaccination with ChAdOx1 or BNT162b2 plus an age-appropriate influenza vaccine raises no safety concerns and preserves antibody responses to both vaccines. Concomitant vaccination with both COVID-19 and influenza vaccines over the next immunisation season should reduce the burden on health-care services for vaccine delivery, allowing for timely vaccine administration and protection from COVID-19 and influenza for those in need.

BACKGROUND: In chronic central serous chorioretinopathy (CSCR), fluid accumulates in the subretinal space. CSCR is a common visually disabling condition that develops in individuals up to 60 years of age, and there is no definitive treatment. Previous research suggests the mineralocorticoid receptor antagonist, eplerenone, is effective for treating CSCR; however, this drug is not licensed for the treatment of patients with CSCR. We aimed to evaluate whether eplerenone was superior to placebo in terms of improving visual acuity in patients with chronic CSCR. METHODS: This randomised, double-blind, parallel-group, multicentre placebo-controlled trial was done at 22 hospitals in the UK. Participants were eligible if they were aged 18-60 years and had had treatment-naive CSCR for 4 months or more. Patients were randomly assigned (1:1) to either the eplerenone or the placebo group by a trial statistician through a password-protected system online. Allocation was stratified by best-corrected visual acuity (BCVA) and hospital. Patients were given either oral eplerenone (25 mg/day for 1 week, increasing to 50 mg/day for up to 12 months) plus usual care or placebo plus usual care for up to 12 months. All participants, care teams, outcome assessors, pharmacists, and members of the trial management group were masked to the treatment allocation. The primary outcome was BCVA, measured as letters read, at 12 months. All outcomes apart from safety were analysed on a modified intention-to-treat basis (participants who withdrew consent without contributing a post-randomisation BCVA measurement were excluded from the primary analysis population and from most secondary analysis populations). The trial is registered with ISRCTN, ISRCTN92746680, and is completed. FINDINGS: Between Jan 11, 2017, and Feb 22, 2018, we enrolled and randomly assigned 114 patients to receive either eplerenone (n=57) or placebo (n=57). Three participants in the placebo group withdrew consent without contributing a post-randomisation BCVA measurement and were excluded from the primary outcome analysis population. All patients from the eplerenone group and 54 patients from the placebo group were included in the primary outcome. Modelled mean BCVA at 12 months was 79·5 letters (SD 4·5) in the placebo group and 80·4 letters (4·6) in the eplerenone group, with an adjusted estimated mean difference of 1·73 letters (95% CI -1·12 to 4·57; p=0·24) at 12 months. Hyperkalaemia occurred in eight (14%) patients in each group. No serious adverse events were reported in the eplerenone group and three unrelated serious adverse events were reported in the placebo group (myocardial infarction [anticipated], diverticulitis [unanticipated], and metabolic surgery [unanticipated]). INTERPRETATION: Eplerenone was not superior to placebo for improving BCVA in people with chronic CSCR after 12 months of treatment. Ophthalmologists who currently prescribe eplerenone for CSCR should discontinue this practice.

OBJECTIVE: Endovascular aneurysm repair (EVAR) is the most commonly used method to repair abdominal aortic aneurysms. EVAR can be performed using a variety of anaesthetic techniques, including general anaesthetic (GA), regional anaesthetic (RA), and local anaesthetic (LA), but little is known about the effects that each of these anaesthetic modes have on patient outcome. The aim of this study was to assess the effect of anaesthetic technique on early outcomes after elective EVAR. METHODS: Data from the UK's National Vascular Registry were analysed. All patients undergoing elective standard infrarenal EVAR between 1 January 2014 and 31 December 2016 were included. Patients with a symptomatic aneurysm treated semi-electively were excluded. The primary outcome was in hospital death within 30 days of surgery. Secondary outcomes included post-operative complications and length of hospital stay. Time to event outcomes were compared using Cox proportional hazards regression adjusted for confounders, including British Aneurysm Repair score (a validated aneurysm risk prediction score that is calculated using age, sex, creatinine, cardiac disease, electrocardiogram, previous aortic surgery, white blood cell count, serum sodium, abdominal aortic aneurysm diameter, and American Society of Anaesthesiologists grade) and chronic lung disease. RESULTS: A total of 9783 patients received an elective, standard infrarenal EVAR (GA, n = 7069; RA, n = 2347; and LA, n = 367) across 89 hospitals. RA and/or LA was used in 82 hospitals. There were 64 in hospital deaths within 30 days, 50 (0.9% mortality at 30 days, 95% confidence interval [CI] 0.7-1.2) in the GA group, 11 (0.6%, 95% CI 0.3-1.1) in the RA group, and three (1.5%, 95% CI 0.5-4.7) in the LA group. The mortality rate differed between groups (p = .03) and was significantly lower in the RA group compared with the GA group (adjusted hazard ratio [aHR] RA/GA 0.37 [95% CI 0.17-0.81]; LA/GA 0.63 [95% CI 0.15-2.69]). The median length of stay was two days for all modes of anaesthesia, but patients were discharged from hospital more quickly in the RA and LA groups than the GA group (aHR RA/GA 1.10 [95% CI 1.03-1.17]; LA/GA 1.15 [95% CI 1.02-1.29]). Overall, 20.7% of patients experienced one or more complications (GA group, 22.1%; RA group, 16.8%; LA group, 17.7%) and pulmonary complications occurred with similar frequency in the three groups (overall 2.4%, adjusted odds ratio RA/GA 0.93 [95% CI 0.66-1.32]; LA/GA 0.82 [95% CI 0.41-1.63]). CONCLUSION: Thirty day mortality was lower with RA than with GA, but mode of anaesthesia was not associated with increased complications for patients undergoing elective standard infrarenal EVAR.

The ComFluCOV trial randomized 679 participants to receive an age-appropriate influenza vaccine, or placebo, alongside their second COVID-19 vaccine. Concomitant administration was shown to be safe, and to preserve systemic immune responses to both vaccines. Here we report on a secondary outcome of the trial investigating SARS-CoV-2-specific mucosal antibody responses. Anti-spike IgG and IgA levels in saliva were measured with in-house ELISAs. Concomitant administration of an influenza vaccine did not affect salivary anti-spike IgG positivity rates to Pfizer/BioNTech BNT162b2 (99.1 cf. 95.6%), or AstraZeneca ChAdOx1 (67.8% cf. 64.9%), at 3-weeks post-vaccination relative to placebo. Furthermore, saliva IgG positively correlated with serum titres highlighting the potential utility of saliva for assessing differences in immunogenicity in future vaccine studies. Mucosal IgA was not detected in response to either COVID-19 vaccine, reinforcing the need for novel vaccines capable of inducing sterilising immunity or otherwise reducing transmission. The trial is registered as ISRCTN 14391248.

Objectives: Surgery through a single port may be less painful because access is supplied by 1 intercostal nerve or more painful because multiple instruments are used in 1 port. We analyzed data collected from the video-assisted thoracoscopic surgery group of a randomized controlled trial to compare differences in pain up to 1 year. Methods: Groups were compared in a prespecified exploratory analysis using direct (regression) and indirect comparison (difference with respect to thoracotomy). In-hospital visual analogue scale pain scores were used, and analgesic ratios were calculated. After discharge, pain was evaluated using European Organization for Research and Treatment of Cancer Quality of Life Questionnaires-Core 30 scores up to 1 year. Results: From July 2015 to February 2019, we randomized 503 participants. After excluding 50 participants who did not receive lobectomy, surgery was performed using a single port in 42 participants (predominately by a single surgeon), multiple ports in 166 participants, and thoracotomy in 245 participants. No differences were observed in-hospital between single- and multiple-port video-assisted thoracoscopic surgery when modeled using a direct comparison, mean difference of -0.24 (95% CI, -1.06 to 0.58) or indirect comparison, mean difference of -0.33 (-1.16 to 0.51). Mean analgesic ratio (single/multiple port) was 0.75 (0.64 to 0.87) for direct comparison and 0.90 (0.64 to 1.25) for indirect comparison. After discharge, pain for single-port video-assisted thoracoscopic surgery was lower than for multiple-port video-assisted thoracoscopic surgery (first 3 months), and corresponding physical function was higher up to 12 months. Conclusions: There were no consistent differences for in-hospital pain when lobectomy was undertaken using 1 or multiple ports. However, better pain scores and physical function were observed for single-port surgery after discharge.
RESUMO
BACKGROUND: Extended pleurectomy decortication for complete macroscopic resection for pleural mesothelioma has never been evaluated in a randomised trial. The aim of this study was to compare outcomes after extended pleurectomy decortication plus chemotherapy versus chemotherapy alone. METHODS: MARS 2 was a phase 3, national, multicentre, open-label, parallel two-group, pragmatic, superiority randomised controlled trial conducted in the UK. The trial took place across 26 hospitals (21 recruiting only, one surgical only, and four recruiting and surgical). Following two cycles of chemotherapy, eligible participants with pleural mesothelioma were randomly assigned (1:1) to surgery and chemotherapy or chemotherapy alone using a secure web-based system. Individuals aged 16 years or older with resectable pleural mesothelioma and adequate organ and lung function were eligible for inclusion. Participants in the chemotherapy only group received two to four further cycles of chemotherapy, and participants in the surgery and chemotherapy group received pleurectomy decortication or extended pleurectomy decortication, followed by two to four further cycles of chemotherapy. It was not possible to mask allocation because the intervention was a major surgical procedure. The primary outcome was overall survival, defined as time from randomisation to death from any cause. Analyses were done on the intention-to-treat population for all outcomes, unless specified. This study is registered with ClinicalTrials.gov, NCT02040272, and is closed to new participants. FINDINGS: Between June 19, 2015, and Jan 21, 2021, of 1030 assessed for eligibility, 335 participants were randomly assigned (169 to surgery and chemotherapy, and 166 to chemotherapy alone). 291 (87%) participants were men and 44 (13%) women, and 288 (86%) were diagnosed with epithelioid mesothelioma. At a median follow-up of 22·4 months (IQR 11·3-30·8), median survival was shorter in the surgery and chemotherapy group (19·3 months [IQR 10·0-33·7]) than in the chemotherapy alone group (24·8 months [IQR 12·6-37·4]), and the difference in restricted mean survival time at 2 years was -1·9 months (95% CI -3·4 to -0·3, p=0·019). There were 318 serious adverse events (grade ≥3) in the surgery group and 169 in the chemotherapy group (incidence rate ratio 3·6 [95% CI 2·3 to 5·5], p<0·0001), with increased incidence of cardiac (30 vs 12; 3·01 [1·13 to 8·02]) and respiratory (84 vs 34; 2·62 [1·58 to 4·33]) disorders, infection (124 vs 53; 2·13 [1·36 to 3·33]), and additional surgical or medical procedures (15 vs eight; 2·41 [1·04 to 5·57]) in the surgery group. INTERPRETATION: Extended pleurectomy decortication was associated with worse survival to 2 years, and more serious adverse events for individuals with resectable pleural mesothelioma, compared with chemotherapy alone.

BACKGROUND: Lung cancer is the leading cause of cancer death. Surgery remains the main method of managing early-stage disease. Minimal-access video-assisted thoracoscopic surgery results in less tissue trauma than open surgery; however, it is not known if it improves patient outcomes. OBJECTIVE: To compare the clinical effectiveness and cost-effectiveness of video-assisted thoracoscopic surgery lobectomy with open surgery for the treatment of lung cancer. DESIGN, SETTING AND PARTICIPANTS: A multicentre, superiority, parallel-group, randomised controlled trial with blinding of participants (until hospital discharge) and outcome assessors conducted in nine NHS hospitals. Adults referred for lung resection for known or suspected lung cancer, with disease suitable for both surgeries, were eligible. Participants were followed up for 1 year. INTERVENTIONS: Participants were randomised 1 : 1 to video-assisted thoracoscopic surgery lobectomy or open surgery. Video-assisted thoracoscopic surgery used one to four keyhole incisions without rib spreading. Open surgery used a single incision with rib spreading, with or without rib resection. MAIN OUTCOME MEASURES: The primary outcome was self-reported physical function (using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30) at 5 weeks. Secondary outcomes included upstaging to pathologic node stage 2 disease, time from surgery to hospital discharge, pain in the first 2 days, prolonged pain requiring analgesia at > 5 weeks, adverse health events, uptake of adjuvant treatment, overall and disease-free survival, quality of life (Quality of Life Questionnaire Core 30, Quality of Life Questionnaire Lung Cancer 13 and EQ-5D) at 2 and 5 weeks and 3, 6 and 12 months, and cost-effectiveness. RESULTS: A total of 503 patients were randomised between July 2015 and February 2019 (video-assisted thoracoscopic surgery, n = 247; open surgery, n = 256). One participant withdrew before surgery. The mean age of patients was 69 years; 249 (49.5%) patients were men and 242 (48.1%) did not have a confirmed diagnosis. Lobectomy was performed in 453 of 502 (90.2%) participants and complete resection was achieved in 429 of 439 (97.7%) participants. Quality of Life Questionnaire Core 30 physical function was better in the video-assisted thoracoscopic surgery group than in the open-surgery group at 5 weeks (video-assisted thoracoscopic surgery, n = 247; open surgery, n = 255; mean difference 4.65, 95% confidence interval 1.69 to 7.61; p = 0.0089). Upstaging from clinical node stage 0 to pathologic node stage 1 and from clinical node stage 0 or 1 to pathologic node stage 2 was similar (p ≥ 0.50). Pain scores were similar on day 1, but lower in the video-assisted thoracoscopic surgery group on day 2 (mean difference -0.54, 95% confidence interval -0.99 to -0.09; p = 0.018). Analgesic consumption was 10% lower (95% CI -20% to 1%) and the median hospital stay was less (4 vs. 5 days, hazard ratio 1.34, 95% confidence interval 1.09, 1.65; p = 0.006) in the video-assisted thoracoscopic surgery group than in the open-surgery group. Prolonged pain was also less (relative risk 0.82, 95% confidence interval 0.72 to 0.94; p = 0.003). Time to uptake of adjuvant treatment, overall survival and progression-free survival were similar (p ≥ 0.28). Fewer participants in the video-assisted thoracoscopic surgery group than in the open-surgery group experienced complications before and after discharge from hospital (relative risk 0.74, 95% confidence interval 0.66 to 0.84; p < 0.001 and relative risk 0.81, 95% confidence interval 0.66 to 1.00; p = 0.053, respectively). Quality of life to 1 year was better across several domains in the video-assisted thoracoscopic surgery group than in the open-surgery group. The probability that video-assisted thoracoscopic surgery is cost-effective at a willingness-to-pay threshold of £20,000 per quality-adjusted life-year is 1. LIMITATIONS: Ethnic minorities were under-represented compared with the UK population (< 5%), but the cohort reflected the lung cancer population. CONCLUSIONS: Video-assisted thoracoscopic surgery lobectomy was associated with less pain, fewer complications and better quality of life without any compromise to oncologic outcome. Use of video-assisted thoracoscopic surgery is highly likely to be cost-effective for the NHS. FUTURE WORK: Evaluation of the efficacy of video-assisted thoracoscopic surgery with robotic assistance, which is being offered in many hospitals.

BACKGROUND: Lung cancer is a common cause of cancer death worldwide. If the disease is caught early, the part of the lung containing the tumour can be removed in an operation called a lobectomy. The operation can be carried out through a large cut so that the surgeon has a full view of the lung, which is called open surgery, or using several small cuts and a camera, which is called video-assisted thoracoscopic (keyhole) surgery. It is thought that, as keyhole surgery is less invasive, patients recover quicker. However, to the best of our knowledge, there are no high-quality research studies that are applicable to UK practice to support this. This study was conducted so that it could be determined, based on high-quality evidence, which operation provides the best treatment and recovery for patients. WHO PARTICIPATED?: Five hundred and three adults referred for lobectomy for known or suspected lung cancer from nine hospitals in the UK. WHAT WAS INVOLVED?: Participants were randomly allocated to either receive keyhole or open surgery. Participants were followed up for 12 months. We collected information on further treatment, hospital visits, safety information and disease progression over this period. Participants were also asked to complete questionnaires about their health and recovery. WHAT DID THE TRIAL FIND?: For patients with early-stage lung cancer who underwent a lobectomy, keyhole surgery led to less pain, less time in hospital and better quality of life than open surgery, without having a detrimental effect on cancer progression or survival. Keyhole surgery was found to be cost-effective and to provide excellent value for money for the NHS.

BACKGROUND: There is limited randomized evidence on the comparative outcomes of early-stage lung cancer resection by video-assisted thoracoscopic surgery (VATS) versus open resection. METHODS: We conducted a parallel-group multicenter randomized trial that recruited participants with known or suspected early-stage lung cancer and randomly assigned them to open or VATS resection of their lesions. The primary outcome was physical function at 5 weeks as a measure of recovery using the European Organisation for Research and Treatment of Cancer core health-related quality of life questionnaire (QLQ-C30) (scores range from 0 to 100, with higher scores indicating better function; the clinical minimally important difference for improvement is 5 points). We followed the patients for an additional 47 weeks for other outcomes. RESULTS: A total of 503 participants were randomly assigned (247 to VATS and 256 to open lobectomy). At 5 weeks, median physical function was 73 in the VATS group and 67 in the open surgery group, with a mean difference of 4.65 points (95% confidence interval, 1.69 to 7.61). Of the participants allocated to VATS, 30.7% had serious adverse events after discharge compared with 37.8% of those allocated to open surgery (risk ratio, 0.81 [95% confidence interval, 0.66 to 1.00]). At 52 weeks, there were no differences in cancer progression-free survival (hazard ratio, 0.74 [0.43 to 1.27]) or overall survival (hazard ratio, 0.67 [0.32 to 1.40]). CONCLUSIONS: VATS lobectomy for lung cancer is associated with a better recovery of physical function in the 5 weeks after random assignment compared with open surgery. Long-term oncologic outcomes will require continued follow-up to assess.

OBJECTIVES: To investigate the effect of preoperative volume replacement therapy (VRT) on renal function, health outcome and time to fitness for discharge in diabetic patients undergoing coronary artery bypass grafting (CABG). METHODS: In 2 parallel randomized controlled trials, diabetic patients were allocated to preoperative VRT (1 ml/kg/h of Hartmann's solution for 12 h) or usual care. Primary outcome was time to fitness for discharge. Secondary outcomes included acute kidney injury, postoperative complications, patient-reported quality of life (QoL), hospital resource use and markers of renal, cardiac and inflammatory injury. RESULTS: In total, 169 patients were randomized (84 VRT, 85 usual care; mean age 64 years; 88% male). Time to fitness for discharge was similar between groups [median 6 days; interquartile range 5.0-9.0 in both groups; hazard ratio 0.95, 95% confidence interval (CI) 0.65-1.38; P = 0.78]. Postoperative acute kidney injury was not statistically different (VRT: 27.7% vs usual care: 18.8%, odds ratio 1.72, 95% CI 0.82-3.59; P = 0.15). Estimated glomerular filtration rate (mean difference -0.92, 95% CI -4.18 to 2.25; P = 0.56), microalbumin/creatinine ratio [geometric mean ratio (GMR) 1.16, 95% CI 0.94-1.42; P = 0.16], N-acetyl-beta-d-glucosaminidase (GMR 1.08, 95% CI 0.83-1.40; P = 0.57), C-reactive protein (GMR 1.00, 95% CI 0.88-1.13; P = 0.94), troponin T (Trop-T; GMR 1.18, 95% CI 0.78-1.79; P = 0.39) and other secondary health outcomes were similar between groups. QoL improved in both groups at 3 months with no difference observed. CONCLUSIONS: The use of preoperative VRT is not superior to usual care in diabetic patients undergoing CABG.
