Group prenatal care for pregnant women with opioid use disorder: Preliminary evidence for acceptability and benefits compared with individual prenatal care.

Introduction: The effectiveness of group prenatal care (G-PNC) compared with individual prenatal care (I-PNC) for women with opioid use disorder (OUD) is unknown. The objectives of this study were to (1) assess the acceptability of co-locating G-PNC at an opioid treatment program and (2) describe the maternal and infant characteristics and outcomes of pregnant women in treatment for OUD who participated in G-PNC and those who did not.

Methods: This was a retrospective cohort study of 71 women (G-PNC n = 15; I-PNC n = 56) who were receiving treatment for OUD from one center and who delivered in 2019.

Mesenchymal stromal cell therapy during ex vivo lung perfusion ameliorates ischemia-reperfusion injury in lung transplantation.

Background: The application of mesenchymal stromal cell (MSC)-based therapy during ex vivo lung perfusion (EVLP) could repair injured donor lungs before transplantation. The aim of this study was to determine the efficacy of MSC therapy performed during EVLP on ischemia-reperfusion injury using a pig lung transplant model.

Methods: Following 24 hours of cold storage, pig lungs were randomly assigned to 2 groups (n = 6 each), the control group without MSC vs the MSC group, where 5 × 10 cells/kg MSCs were delivered through the pulmonary artery during EVLP.

Donor prone positioning protects lungs from injury during warm ischemia.

A large proportion of controlled donation after circulatory death (cDCD) donor lungs are declined because cardiac arrest does not occur within a suitable time after the withdrawal of life-sustaining therapy. Improved strategies to preserve lungs after asystole may allow the recovery team to arrive after death actually occurs and enable the recovery of lungs from more cDCD donors. The aim of this study was to determine the effect of donor positioning on the quality of lung preservation after cardiac arrest in a cDCD model.

Pig lung transplant survival model.

Although lung transplant is a life-saving therapy for some patients, primary graft dysfunction (PGD) is a leading cause of mortality and morbidity soon after a transplant. Ischemia reperfusion injury is known to be one of the most critical factors in PGD development. PGD is by definition an acute lung injury syndrome that occurs during the first 3 d following lung transplantation.
