Effectiveness of complement inhibitors against refractory antibody-mediated rejection of lung transplantation: Two clinical cases.

Antibody-mediated rejection (AMR) has been recognized as a significant cause of acute and chronic lung allograft dysfunction after lung transplantation. Some treatments, eculizumab, an anti-complement (C)5 component monoclonal antibody (Mab), seem to have a promising effect in the management of some patients with AMR. We present two patients with acute AMR after lung transplantation who received the anti-C5 Mab therapy.

The impact of a virtual wellness course for adults with intellectual and developmental disabilities in the third year of COVID-19.

The current study examines how a virtual wellness intervention may improve health outcomes in adults with intellectual and developmental disabilities. Thirty-six adults with intellectual and developmental disabilities participated in the wellness intervention. Outcome measures related to satisfaction, mental health, wellbeing, health behaviours and overall health were completed at three time points (pre, post and follow-up).

Impact of vaccinations, boosters and lockdowns on COVID-19 waves in French Polynesia.

Estimating the impact of vaccination and non-pharmaceutical interventions on COVID-19 incidence is complicated by several factors, including successive emergence of SARS-CoV-2 variants of concern and changing population immunity from vaccination and infection. We develop an age-structured multi-strain COVID-19 transmission model and inference framework to estimate vaccination and non-pharmaceutical intervention impact accounting for these factors. We apply this framework to COVID-19 waves in French Polynesia and estimate that the vaccination programme averted 34.

Impact on blood safety of the last arboviruses outbreaks in French Polynesia (2012-2018).

Background: Several successive arbovirus outbreaks have affected French Polynesia (FP) in the recent past years due to different dengue serotypes (DENV) present for several decades, Zika (ZIKV) (2013-2014) and chikungunya (CHIKV) (2014-2015) viruses with a potential impact on blood safety and blood supply due to the geographical isolation of these islands. This study reports an assessment of the impact of these outbreaks on blood products supply and infectious safety in FP and discuss the effectiveness of implemented preventive measures.

Methods: To ensure the infectious safety of blood products during outbreaks, several measures have successively been introduced as the selection of donors suspected of infection, the nucleic acid testing (NAT) and the pathogen reduction of platelets and plasmas.
