Introduction

Lung transplantation (LTx) aims at improving survival and quality of life for patients with end-stage lung diseases. Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is used as intraoperative support for LTx, despite no precise guidelines for its initiation. We aim to evaluate two strategies of VA-ECMO initiation in the perioperative period in patients with obstructive or restrictive lung disease requiring bilateral LTx. In the control ‘on-demand’ arm, high haemodynamic and respiratory needs will dictate VA-ECMO initiation; in the experimental ‘systematic’ arm, VA-ECMO will be pre-emptively initiated. We hypothesise a ‘systematic’ strategy will increase the number of ventilatory-free days at day 28.

Methods and analysis

We designed a multicentre randomised controlled trial in parallel groups. Adult patients with obstructive or restrictive lung disease requiring bilateral LTx, without a formal indication for pre-emptive VA-ECMO before LTx, will be included. Patients with preoperative pulmonary hypertension with haemodynamic collapse, ECMO as a bridge to transplantation, severe hypoxaemia or hypercarbia will be secondarily excluded. In the systematic group, VA-ECMO will be systematically implanted before the first pulmonary artery cross-clamp. In the on-demand group, VA-ECMO will be implanted intraoperatively if haemodynamic or respiratory indices meet preplanned criteria. Non-inclusion, secondary exclusion and VA-ECMO initiation criteria were validated by a Delphi process among investigators. Postoperative weaning of ECMO and mechanical ventilation will be managed according to best practice guidelines. The number of ventilator-free days at 28 days (primary endpoint) will be compared between the two groups in the intention-to-treat population. Secondary endpoints encompass organ failure occurrence, day 28, day 90 and year 1 vital status, and adverse events.

Ethics and dissemination

The sponsor is the Assistance Publique–Hôpitaux de Paris. The ECMOToP protocol version 2.1 was approved by Comité de Protection des Personnes Ile de France VIII. Results will be published in international peer-reviewed medical journals.

Climate footprint of industry-sponsored clinical research: an analysis of a phase-1 randomised clinical study and discussion of opportunities to reduce its impact

Por: LaRoche · J. K. · Alvarenga · R. · Collins · M. · Costelloe · T. · De Soete · W. · Faludi · J. · Rens · K.
Objective

This study aims to calculate the global warming potential, in carbon dioxide (CO2) equivalent emissions, from all in-scope activities involved in a phase-1 clinical study.

Design

Retrospective analysis.

Data source

Internal data held by Janssen Pharmaceuticals.

Studies included

Janssen-sponsored TMC114FD1HTX1002 study conducted between 2019 and 2021.

Main outcome

Measure CO2 equivalents (CO2e) for in-scope clinical trial activities calculated according to intergovernmental panel on climate change 2021 impact assessment methodology.

Results

The CO2e emissions generated by the trial were 17.65 tonnes. This is equivalent to the emissions generated by driving an average petrol-fueled family car 71 004 km or roughly 1.8 times around the circumference of the Earth. Commuting to the clinical site by the study participants generated the most emissions (5419 kg, 31% of overall emissions), followed by trial site utilities (2725 kg, 16% of overall emissions) and site staff travel (2560 kg, 15% of overall emissions). In total, the movement of people (participant travel, site staff travel and trial site staff travel) accounted for 8914 kg or 51% of overall trial emissions.

Conclusions

Decentralised trial models which seek to bring clinical trial operations closer to the participant offer opportunities to reduce participant travel. The electrification of sponsor vehicle fleets and society’s transition towards electric vehicles may result in further reductions.

Objective

This study aims to evaluate whether the first wave of the COVID-19 pandemic resulted in a deterioration in the quality of care for socially and/or clinically vulnerable stroke and ST-segment elevation myocardial infarction (STEMI) patients.

Design

Two cohorts of STEMI and stroke patients in the Aquitaine neurocardiovascular registry.

Setting

Six emergency medical services, 30 emergency units, 14 hospitalisation units and 11 catheterisation laboratories in the Aquitaine region in France.

Participants

This study involved 9218 patients (6436 stroke and 2782 STEMI patients) in the neurocardiovascular registry from January 2019 to August 2020.

Primary outcome measures

Care management times in both cohorts: first medical contact-to-procedure time for the STEMI cohort and emergency unit admission-to-imaging time for the stroke cohort. Associations between social (deprivation index) and clinical (age >65 years, neurocardiovascular history) vulnerabilities and care management times were analysed using multivariate linear mixed models, with an interaction on the time period (pre-wave, per-wave and post-first COVID-19 wave).

Results

The first medical contact procedure time was longer for elderly (p

Conclusions

This study revealed pre-existing inequalities in care management times for vulnerable STEMI and stroke patients; however, these inequalities were neither accentuated nor reduced during the first COVID-19 wave. Measures implemented during the crisis did not alter the structured emergency pathway for these patients.

Poorer subjective mental health among girls: Artefact or real? Examining whether interpretations of what shapes mental health vary by sex

by Susan P. Phillips, Fiona Costello, Naomi Gazendam, Afshin Vafaei

Background

Despite reporting poorer self-rated mental health (SRMH) than boys, girls exhibit greater resilience and academic achievement, and less risk taking or death by suicide. Might this apparent paradox be an artefact arising from girls’ and boys’ different interpretations of the meaning of SRMH? We examined whether the indicator, SRMH, had a different meaning for girls and boys.

Methods

In 2021–2, we circulated social media invitations for youth age 13–18 to complete an online survey about their mental health, and which of 26 individual and social circumstances shaped that rating. All data were submitted anonymously with no link to IP addresses. After comparing weightings for each characteristic, factor analyses identified domains for the whole group and for girls and boys.

Results

Poor SRMH was reported by 47% of 506 girls and 27.8% of 216 boys. In general, circumstances considered important to this rating were similar for all, although boys focussed more on sense of identity, self-confidence, physical well-being, exercise, foods eaten and screen time, while girls paid more attention to having a boyfriend or girlfriend, comparisons with peers, and school performance. With factor analysis and common to boys and girls, domains of resilience, behavior/community, family, relationships with peers and future vision emerged. Girls’ poorer SRMH did not arise from a more expansive interpretation of mental health. Instead, it may reflect perceived or real disadvantages in individual or social circumstances. Alternatively, girls’ known greater resilience may propel lower SRMH which they use intuitively to motivate future achievement and avoid the complacency of thinking that ‘all is well’.

Conclusions

The relative similarity of attributes considered before rating one’s mental health suggests validity of this subjective measure among girls and boys.

Cohort profile: COBLAnCE: a French prospective cohort to study prognostic and predictive factors in bladder cancer and to generate real-world data on treatment patterns, resource use and quality of life

Purpose

Bladder cancer is a complex disease with a wide range of outcomes. Clinicopathological factors only partially explain the variability between patients in prognosis and treatment response. There is a need for large cohorts collecting extensive data and biological samples to: (1) investigate gene-environment interactions, pathological/molecular classification and biomarker discovery; and (2) describe treatment patterns, outcomes, resource use and quality of life in a real-world setting.

Participants

COBLAnCE (COhort to study BLAdder CancEr) is a French national prospective cohort of patients with bladder cancer recruited between 2012 and 2018 and followed for 6 years. Data on patient and tumour characteristics, treatments, outcomes and biological samples are collected at enrolment and during the follow-up.

Findings to date

We describe the cohort at enrolment according to baseline surgery and tumour type. In total, 1800 patients were included: 1114 patients with non-muscle-invasive bladder cancer (NMIBC) and 76 patients with muscle-invasive bladder cancer (MIBC) had transurethral resection of a bladder tumour without cystectomy, and 610 patients with NMIBC or MIBC underwent cystectomy. Most patients had a solitary lesion (56.3%) without basement membrane invasion (71.7% of Ta and/or Tis). Half of the patients with cystectomy were stage ≤T2 and 60% had non-continent diversion. Surgery included local (n=298) or super-extended lymph node dissections (n=11) and prostate removal (n=492). Among women, 16.5% underwent cystectomy and 81.4% anterior pelvectomy.

Future plans

COBLAnCE will be used for long-term studies of bladder cancer with focus on clinicopathological factors and molecular markers. It will lead to a much-needed improvement in the understanding of the disease. The cohort provides valuable real-world data, enabling researchers to study various research questions, assess routine medical practices and guide medical decision-making.
