Effect of crew resource management training in a multidisciplinary obstetrical setting

Objective To assess the effect of a Crew Resource Management (CRM) intervention specifically designed to improve teamwork and communication skills in a multidisciplinary obstetrical setting. Method Design-A before-and-after cross-sectional study designed to assess participants' satisfaction, learning and change in behaviour, according to Kirkpatrick's evaluation framework for training programmes. Setting-Labour and delivery units of a large university-affiliated hospital. Participants-Two hundred and thirty nine midwives, nurses, physicians and technicians from the department of anaesthesia, obstetrics and paediatrics. Intervention-All participants took part in a CRM-based training programme specifically designed to improve teamwork and communication skills. Principal measures of outcome-We assessed participants' satisfaction by means of a 10-item standardized questionnaire. A 36-item survey was administered before and after the course to assess participants' learning. Behavioural change was assessed by a 57-item safety attitude questionnaire measuring staff's change in attitude to safety over 1 year of programme implementation. Results Most participants valued the experience highly and 63-90% rated their level of satisfaction as being very high. Except for seven items, the 36-item survey testing participants' learning demonstrated a significant change (P < 0.05) towards better knowledge of teamwork and shared decision making after the training programme. Over the year of observation, there was a positive change in the team and safety climate in the hospital [odds ratio (OR) 2.9, 95% confidence interval (CI) (1.3-6.3) to OR 4.7, 95% CI (1.2-17.2)]. **There was also improved stress recognition [OR 2.4, 95% CI (1.2-4.8) to OR 3.0, 95% CI (1.0-8.8)]. Conclusion The implementation of a training programme based on CRM in a multidisciplinary obstetrical setting is well accepted and contributes to a significant improvement in interprofessional teamwor

The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance

INTRODUCTION Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic. RATIONALE We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs). RESULTS Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants. CONCLUSION Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century

Ex utero intrapartum treatment (EXIT), a resuscitation option for intra-thoracic foetal pathologies

The ex utero intrapartum treatment (EXIT) procedure is designed to guarantee sufficient oxygenation for a foetus at risk of airway obstruction. This is achieved by improving lung ventilation, usually by establishing an airway during caesarean delivery whilst preserving the foetal-placental circulation temporarily. Indications for the EXIT procedure have extended from its original use in reversing iatrogenic tracheal obstruction in congenital diaphragmatic hernia to naturally occurring upper airway obstructions. We report our experience with a new and rarely mentioned indication for the EXIT procedure, intra-thoracic volume expansions. The elaboration of lowest risk scenarios through balancing risks with alternative options, foetal or neonatal intervention and coordination between professionals from various disciplines are the most important conditions for a successful EXIT procedure. The EXIT procedure requires a caesarean section that specifically differs from the traditional caesarean section during which uterine tone is maintained to minimize maternal bleeding. To guarantee foetal oxygenation during the EXIT procedure, profound uterine relaxation is desired. To gain time with optimal placental oxygenation in order to safely perform an airway intervention in a baby at risk of hypoxia may require deep inhalation anaesthesia and/or tocolytic agents. We review the EXIT procedure and present a case series from the University Hospital of Geneva that contrasts with the common indication for the EXIT procedure usually based on upper airway obstruction by its exclusive indication for intra-thoracic malformations/diseases

Alteration of circulating Placental Leucine Aminopeptidase (P-LAP) activity in preeclampsia

Placental Leucine Aminopeptiadse (P-LAP) also known as oxytocinase, is secreted by syncytiotrophoblast and increases gradually during pregnancy until delivery. It is a regulator of uterine contractions, of vascular resistance and of volume of the retroplacental blood pool. Recently, it was shown that it could also regulate metalloproteinase 9 activity and thus, invasiveness of trophoblastic cells. Since development of preeclampsia could be initiated by decreased cytotrophoblastic invasion of spiral arterioles and a reduced uteroplacental perfusion, we speculate that circulating P-LAP activity could be decreased during preeclampsia
