Thermal relaxation time and photothermal optomechanical force in sliced photonic crystal silicon nanobeams.

Optomechanical devices based on sliced silicon photonic crystal nanobeams could have several use cases in future quantum technologies, especially as quantum transducers between different quantum systems. To create the required pure mechanical states at low temperatures, an understanding of photon absorption, thermal relaxation, and the associated photothermal force is crucial. Here, we characterize the strength of the photothermal force in sliced silicon nanobeam resonators.

Evaluation of community nurse-led traumatic tube displacements.

Home enteral tube feeding (HEF) has many benefits and is largely safe practice. Some complications have historically required intervention in the acute setting, including traumatic displacement of feeding tubes (i.e.

Interventions, outcomes and outcome measurement instruments in stillbirth care research: A systematic review to inform the development of a core outcome set.

Background: A core outcome set could address inconsistent outcome reporting and improve evidence for stillbirth care research, which have been identified as an important research priority.

Objectives: To identify outcomes and outcome measurement instruments reported by studies evaluating interventions after the diagnosis of a stillbirth.

Search Strategy: Amed, BNI, CINAHL, ClinicalTrials.

Resilience and vulnerability of maternity services in Zimbabwe: a comparative analysis of the effect of Covid-19 and lockdown control measures on maternal and perinatal outcomes, a single-centre cross-sectional study at Mpilo Central Hospital.

Background: On the 27 of March 2020 the Zimbabwean government declared the Covid-19 pandemic a 'national disaster'. Travel restrictions and emergency regulations have had significant impacts on maternity services, including resource stock-outs, and closure of antenatal clinics during the lockdown period. Estimates of the indirect impact of Covid-19 on maternal and perinatal mortality was expected it to be considerable, but little data was yet available.

NHS England-funded CT fractional flow reserve in the era of the ISCHEMIA trial.

Background: The National Institute for Health and Care Excellence (NICE) 2016 guidelines (CG95) recommend patients with new stable chest pain be investigated with computed tomography coronary angiography (CTCA). An updated guideline (MTG32) recommended using CT fractional flow reserve (CTFFR) as a gatekeeper to invasive coronary angiography (ICA) for patients with coronary stenosis on CTCA. Subsequently, NHS England negotiated a UK-wide contract with HeartFlow, the provider of CTFFR.
