Establishing information needs and research priorities in response to the Covid-19 pandemic in the local maternity setting.

The purpose of this project was to identify gaps in the current evidence base and to identify research priorities in the local context during the Covid-19 pandemic. This paper reports on the application and adaptation of the CHNRI methodology which follows a series of criteria setting, filtering and scoring exercises. The views of maternity care professionals, midwifery managers and leaders, women and families were continually sought throughout the project stages. We found the CHNRI methodology to be a useful framework to highlight topics with greater or smaller consensus within a relatively short time frame and with minimal burden to participants. The criteria were defined to focus on research topics where no existing or on-going studies were identified and topics likely to lead to improvements in care with relevance beyond the Covid-19 pandemic.

Aseismic mid-crustal magma reservoir at Cleveland Volcano imaged through novel receiver function analyses.

Processes related to eruptions at arc volcanoes are linked by structures that transect the entire crust. Imaging the mid- to lower-crustal portions (here, ~5-15 km and >15 km respectively) of these magmatic systems where intermediate storage may occur has been a longstanding challenge. Tomography, local seismic source studies, geodetic, and geochemical constraints, are typically most sensitive to shallow (<5 km) storage and/or have insufficient resolution at these depths. Geophysical methods are even further limited at frequently-erupting volcanoes where well-developed trans-crustal magmatic systems are likely to exist, due to a lack of deep seismicity. Here we show direct evidence for mid-crustal magma storage beneath the frequently erupting Cleveland volcano, Alaska, using a novel application of seismic receiver functions. We use P-s scattered waves from the Moho as virtual sources to investigate S-wave velocities between the Moho and the surface. Our forward modeling approach allows us to provide direct constraints on the geometry of low velocity regions beneath volcanoes despite having a comparatively sparse seismic network. Our results show clear evidence of mid-crustal magma storage beneath the depths of located volcanic seismicity. Future work using similar approaches will enable an unprecedented comparative examination of magmatic systems beneath sparsely instrumented volcanoes globally.

Reducing the risk of baby falls in maternity units.

During a 12-month period there were 17 baby falls on the maternity wards at Nottingham University Hospitals Trust; two of the babies who fell were injured. By collecting information about the baby falls and how they happened, we were able to compile a guideline for both preventing and managing baby falls. This formed part of the trust's patient safety programme. We then piloted and implemented risk-prevention strategies for baby falls. These involved a risk assessment to identify women needing closer observation and the installation of bedside cots. These strategies brought about a marked reduction of baby falls and are now being established across all the maternity units across the trust.
