OBJECTIVES Aortic root aneurysms often affect younger patients in whom valve-sparing surgery is challenging. Among current techniques, aortic valve-sparing root replacement described by Tirone David has shown encouraging results. The AORTLANTIC registry was instituted for a multicentre long-term evaluation of this procedure. The current initial study evaluates the hospital outcomes of the procedure. METHODS This is a retrospective study of patients operated between 1 January 2004 and 31 December 2020 in 6 hospitals in western France. All study data were recorded in the national digital database of the French Society of Cardiac Surgery: EPICARD. RESULTS A total of 524 consecutive patients with a mean age of 53 (15.1) years underwent surgery. 13% (n = 68) of patients presented with acute aortic dissection, 16.5% (n = 86) had associated connective tissue pathology and 7.3% (n = 37) had bicuspid aortic valves. Preoperative aortic regurgitation (AR) ≥2/4 was present in 65.3% (n = 341) of patients. Aortic valvuloplasty was required in 18.6% (n = 95) of patients. At discharge, 92.8% (n = 461) of patients had no or 1/4 AR. The stroke rate was 1.9% (n = 10). Intra-hospital mortality was 1.9% (n = 10). CONCLUSIONS The AORTLANTIC registry includes 6 centres in western France with >500 patients. Despite numerous complex cases (acute aortic dissections, bicuspid aortic valves, preoperative AR), aortic valve-sparing root replacement has a low intra-hospital mortality. The initial encouraging results of this multicentre study warrant further long-term evaluation by future studies.

The addition of bevacizumab to chemotherapy (15 mg/kg for six cycles) followed by extended therapy with bevacizumab every 3 weeks for a total of 15 months of treatment improved progression-free survival by 4 months in incompletely resected stage III or IV ovarian cancer. Ovarian cancer is the fourth most common cause of cancer-related deaths in women, with an estimated 200,000 cases and 125,000 deaths occurring annually worldwide. For the past decade, the standard treatment for women with advanced ovarian cancer has been surgery and platinum-based chemotherapy. Attempts to improve this standard two-drug chemotherapy by adding a third cytotoxic drug failed to affect either progression-free survival or overall survival and resulted in an increase in toxic effects. 1 – 4 Although intraperitoneal chemotherapy has extended overall survival by 12 to 17 months, it is an option only for women with advanced ovarian cancer who have a . . .

Background CA-125 alone is widely used to diagnose progressive disease (PD) in platinum-sensitive recurrent ovarian cancer (PSROC) on chemotherapy. However, there are increasing concerns regarding its accuracy. We assessed concordance between progression defined by CA-125 and RECIST using data from the CALYPSO trial. Methods We computed concordance rates for PD by CA-125 and RECIST to determine the positive (PPV) and negative predictive values (NPV). Results Of 769 (79%) evaluable participants, 387 had CA-125 PD, where only 276 had concordant RECIST PD (PPV 71%, 95% CI 67–76%). For 382 without CA-125 PD, 255 had RECIST PD but 127 did not (NPV 33%, 95% CI 29–38). There were significant differences in NPV according to baseline CA-125 (≤100 vs >100: 42% vs 25%, P  < 0.001); non-measurable vs measurable disease (51% vs 26%, P  < 0.001); and platinum-free-interval (>12 vs 6–12 months: 41% vs 14%, P  < 0.001). We observed falling CA-125 levels in 78% of patients with RECIST PD and CA-125 non-PD. Conclusion Approximately 2 in 3 women with PSROC have RECIST PD but not CA-125 PD by GCIG criteria. Monitoring CA-125 levels alone is not reliable for detecting PD. Further research is required to investigate the survival impact of local therapy in radiological detected early asymptomatic PD.

Introduction/Background*Pembrolizumab, an anti-PD-1 antibody, has demonstrated activity in patients with previously treated mismatch repair (MMR) deficient (dMMR; 57.1% objective response rate [ORR] as monotherapy and 63.6% ORR as combination therapy with lenvatinib) and MMR proficient (pMMR; 36.2% ORR as combination therapy with lenvatinib) endometrial cancer. ENGOT-en11/GOG-3053/KEYNOTE-B21 (NCT04634877) is a phase 3, randomized, double-blind study of pembrolizumab or placebo in combination with adjuvant chemotherapy with/without radiotherapy in patients with endometrial cancer.MethodologyEligible patients are ≥18 years old with newly diagnosed, high-risk (stage I/II non-endometrioid or with p53 abnormality and any histology, stage III/IVA), previously untreated endometrial cancer following surgery with curative intent with no evidence of disease post-operatively. Approximately 990 patients are randomized to receive pembrolizumab 200 mg or placebo every 3 weeks (Q3W) for 6 cycles plus chemotherapy (carboplatin area under the curve [AUC] 5/6 plus paclitaxel 175 mg/m2 Q3W or carboplatin AUC 2/2.7 plus paclitaxel 60 mg/m2 QW) in stage 1. Patients receive pembrolizumab 400 mg or placebo Q6W for 6 cycles in stage 2. Radiotherapy (external beam radiotherapy [EBRT] and/or brachytherapy) ± radiosensitizing cisplatin 50 mg/m2 (days 1 and 29) may be administered after completion of chemotherapy. Randomization is stratified by MMR status (pMMR vs dMMR) and, within pMMR, by planned radiation therapy (cisplatin-EBRT vs EBRT vs no EBRT), histology (endometrioid vs non-endometrioid), and International Federation of Gynecology and Obstetrics surgical stage (I/II vs III/IVA). Dual primary endpoints are disease-free survival (DFS; per investigator assessment) and overall survival (OS). Secondary endpoints include DFS (per blinded independent central review), DFS (per investigator assessment) and OS by biomarker status (PD-L1 and tumor mutational burden), safety (per National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0), and quality of life (per European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 [EORTC QLQ-C30] and Endometrial Cancer Module [EORTC QLQ-EN24]). Enrolment began December 2020 and is ongoing at 221 sites in 28 countries.Result(s)*N/AConclusion*N/A

Influenza vaccination remains the most effective tool for reducing seasonal influenza disease burden. Few Low and Middle-Income Countries (LMICs) have robust, sustainable annual influenza national vaccination programs. The Partnership for Influenza Vaccine Introduction (PIVI) was developed as a public-private partnership to support LMICs to develop and sustain national vaccination programs through time-limited vaccine donations and technical support. We review the first 5 years of experience with PIVI, including the concept, country progress toward sustainability, and lesson learned. Between 2013 and 2018, PIVI worked with Ministries of Health in 17 countries. Eight countries have received donated vaccines and technical support; of these, two have transitioned to sustained national support of influenza vaccination and six are increasing national support of the vaccine programs towards full transition to local vaccine program support by 2023. Nine additional countries have received technical support for building the evidence base for national policy development and/or program evaluation. PIVI has resulted in increased use of vaccines in partner countries, and early countries have demonstrated progress towards sustainability, suggesting that a model of vaccine and technical support can work in LMICs. PIVI expects to add new country partners as current countries transition to self-reliance.

Optical coherence tomography provides high-resolution 3D imaging of the posterior segment of the eye. However, quantitative morphological analysis, particularly relevant in retinal degenerative diseases such as glaucoma, has been confined to simple sectorization and averaging with limited spatial sensitivity for detection of clinical markers. In this paper, we present point-wise analysis and visualization of the retinal nerve fiber layer and choroid from cross-sectional data using functional shapes (fshape) registration. The fshape framework matches two retinas, or generates a mean of multiple retinas, by jointly optimizing the surface geometry and functional signals mapped on the surface. We generated group-wise mean retinal nerve fiber layer and choroidal surfaces with the respective layer thickness mapping and showed the difference by age (normal, younger vs. older) and by disease (age-matched older, normal vs. glaucomatous) in the two layers, along with a more conventional sector-based analysis for comparison. The fshape results visualized the detailed spatial patterns of the differences between the age-matched normal and glaucomatous retinal nerve fiber layers, with the glaucomatous layers most significantly thinner in the inferior region close to Bruch's membrane opening. Between the young and older normal cases, choroid was shown to be significantly thinner in the older subjects across all regions, but particularly in the nasal and inferior regions. The results demonstrate a comprehensive and detailed analysis with visualization of morphometric patterns by multiple factors.

Background Since 2004, the uptake of seasonal influenza vaccines in Latin America and the Caribbean has markedly increased. However, vaccine effectiveness (VE) is not routinely measured in the region. We assessed the feasibility of using routine surveillance data collected by sentinel hospitals to estimate influenza VE during 2012 against laboratory-confirmed influenza hospitalizations in Costa-Rica, El Salvador, Honduras and Panama. We explored the completeness of variables needed for VE estimation. Methods We conducted the pilot case–control study at 23 severe acute respiratory infections (SARI) surveillance hospitals. Participant inclusion criteria included children 6 months–11 years and adults ≥60 years targeted for vaccination and hospitalized for SARI during January–December 2012. We abstracted information needed to estimate target group specific VE (i.e., date of illness onset and specimen collection, preexisting medical conditions, 2012 and 2011 vaccination status and date, and pneumococcal vaccination status for children and adults) from SARI case-reports and for children ≤9 years, inquired about the number of annual vaccine doses given. A case was defined as an influenza virus positive by RT-PCR in a person with SARI, while controls were RT-PCR negative. We recruited 3 controls per case from the same age group and month of onset of symptoms. Results We identified 1,186 SARI case-patients (342 influenza cases; 849 influenza-negative controls), of which 994 (84 %) had all the information on key variables sought. In 893 (75 %) SARI case-patients, the vaccination status field was missing in the SARI case-report forms and had to be completed using national vaccination registers (36 %), vaccination cards (30 %), or other sources (34 %). After applying exclusion criteria for VE analyses, 541 (46 %) SARI case-patients with variables necessary for the group-specific VE analyses were selected (87 cases, 236 controls among children; 64 cases, 154 controls among older adults) and were insufficient to provide precise regional estimates (39 % for children and 25 % for adults of minimum sample size needed). Conclusions Sentinel surveillance networks in middle income countries, such as some Latin American and Caribbean countries, could provide a simple and timely platform to estimate regional influenza VE annually provided SARI forms collect all necessary information.
