Using network analysis, which takes a holistic approach to health systems, we aimed to identify which psychosocial burden dimensions are the most central and, thus, critical to prioritising to improve the overall health of people with type 1 diabetes (PwT1D).

A cross-sectional network analysis.

We used data from participants attending 44 diabetes centres in France, who were enrolled in the SFDT1 cohort study between June 2020 and February 2024.

We included 1430 PwT1D (52% women, median age (IQR) 41 (31–52.8) years) who had completed questionnaires on diabetes burden.

The items from questionnaires on diabetes distress, fear of hypoglycaemia, quality of life, treatment burden and the impact of diabetes on education and work.

The network was highly stable (correlation stability coefficient=0.75). We observed nine domains within the network; ‘Loneliness, Worrying & Burnout’ was the most influential. We further grouped the domains into three distinct syndromes labelled ‘Diabetes Distress’, ‘Treatment Burden’ and ‘Impact of Diabetes on Life’. These syndromes reflect the most relevant pillars of the psychosocial burden in PwT1D.

We observed that ‘Loneliness, Worrying & Burnout’ is the most influential psychosocial burden network domain to prioritise for type 1 diabetes care. This new network-based approach opens the path to defining personalised interventions targeting the most critical burden parameters to expect the most significant overall beneficial impact on PwT1D’s health.

Postoperative pulmonary complications (PPCs) are common after cardiac surgery and are associated with significant morbidity and mortality. Lung-protective ventilation strategies have been proposed to reduce PPCs, but the optimal level of positive end-expiratory pressure (PEEP) and the use of alveolar recruitment manoeuvres (RMs) remain controversial.

In this investigator-initiated, multicentre, open, randomised, parallel-group, superiority clinical trial, elective cardiac surgery patients at risk of PPCs will be assigned to one of two intraoperative ventilation strategies: (1) an open-lung ventilation strategy with protective ventilation, moderate PEEP and RMs or (2) a standard protective ventilation with low PEEP and no RM. The primary outcome will be a composite of prolonged (>24 hour) postoperative mechanical ventilation, reintubation for any cause or hospital-acquired pneumonia within 7 days of surgery, or death within 28 days of surgery. Data will be analysed on an intention-to-treat basis.

The VACARM (impact of intraoperatiVe moderAte positive end-expiratory pressure with reCruitment mAnoeuvres versus low positive end-expiRatory pressure on major postoperative pulMonary complications and death after on-pump cardiac surgery in high-risk patients) trial has been approved by an independent ethics committee for all study centres. Recruitment began in July 2021. Results will be published in international peer-reviewed medical journals.
