Magnetic versus crystal field linear dichroism in NiO thin films

We have detected strong dichroism in the Ni $L_{2,3}$ x-ray absorption spectra of monolayer NiO films. The dichroic signal appears to be very similar to the magnetic linear dichroism observed for thicker antiferromagnetic NiO films. A detailed experimental and theoretical analysis reveals, however, that the dichroism is caused by crystal field effects in the monolayer films, which is a non trivial effect because the high spin Ni $3d^{8}$ ground state is not split by low symmetry crystal fields. We present a practical experimental method for identifying the independent magnetic and crystal field contributions to the linear dichroic signal in spectra of NiO films with arbitrary thicknesses and lattice strains. Our findings are also directly relevant for high spin $3d^{5}$ and $3d^{3}$ systems such as LaFeO$_{3}$, Fe$_{2}$O$_{3}$, VO, LaCrO$_{3}$, Cr$_{2}$O$_{3}$, and Mn$^{4+}$ manganate thin films

Assumptions for long-term stochastic population forecasts in 18 European countries: Hypothèses de projections stochastiquesàlong terme des populations de 18 pays européens

The aim of the ‘Uncertain Population of Europe’(UPE) project was to compute long-term stochastic (probabilistic) population forecasts for 18 European countries. We developed a general methodology for constructing predictive distributions for fertility, mortality and migration. The assumptions underlying stochastic population forecasts can be assessed by analysing errors in past forecasts or model-based estimates of forecast errors, or by expert judgement. All three approaches have been used in the project. This article summarizes and discusses the results of the three approaches. It demonstrates how the—sometimes conflicting—results can be synthesized into a consistent set of assumptions about the expected levels and the uncertainty of total fertility rate, life expectancy at birth of men and women, and net migration for 18 European countries

COVID-19 Pandemic Preparedness in a UK Tertiary and Quaternary Children's Hospital: Tales of the Unexpected

We describe the adaptive coping strategies required in the management of a heterogeneous group of SARS-CoV-2 paediatric patients. The diverse range of presentations, presenting in distinct phenotypic waves, exemplified the importance of preparedness for the unknown. Lessons learned will be essential in planning for a likely second wave of SARS-CoV-2

Patient coaching in secondary care:healthcare professionals' views on target group, intervention and coach profile

Background: Not all patients are able to communicate effectively during consultations with medical specialists. Patient coaching has shown to be effective for enhancing communication. Objective: We aimed to get healthcare professionals' views on target groups for patient coaching, on supportive elements in patient coaching and on the necessary qualifications and profile of a patient coach, to further our knowledge on the concept of patient coaching as supportive intervention for patients in consultations with medical specialists. Methods: We chose a qualitative research design and interviewed 18 healthcare professionals (six medical specialists, four family physicians, four community nurses and four nurse specialists/physician assistants) and analysed the verbatim transcripts using Qualitative Analysis Guide of Leuven. After a short introduction of the global concept of patient coaching and presentation of patients' perceived barriers, two interviewers structured the interview around three research questions: which patients could benefit from a patient coach, what should such a coach do and who could act like such a coach? Results: Participants describe patients who could benefit from patient coaching as generally vulnerable (e.g. older age, insufficiently accompanied, lower socioeconomic status, co-morbidity and cognitive problems) but also patients who are situationally vulnerable (e.g. elicited by bad news). Patient coaching should comprise emotional and instrumental support, aiming at reducing stress and improving the processing of medical information. Patient coaching should start from the patient's home and include preparing questions, navigating to and in the hospital, recording information during the consultation, checking understanding and recalling information. Patient coaches should have at least basic medical knowledge and a higher education. Conclusion: Healthcare professionals believe that patient coaching by a trained professional with medical knowledge could be beneficial to patients who are stressed when visiting a medical specialist. Future research should involve the views of patients on patient coaching, focus on investigating to what extent patient coaching is able to reduce stress and support a patient in processing medical information and the preferred patient coach's profile

The Role of the Epinephrine Test in the Diagnosis and Management of Children Suspected of Having Congenital Long QT Syndrome

The epinephrine test has been shown to be a powerful tool to predict the genotype of congenital long QT syndrome (LQTS). The aim of this study was to evaluate its role in the diagnosis and management of LQTS in children. The test (using the Shimizu protocol) was conducted in patients with some evidence of LQTS but in whom clinical and management decisions were challenging (n = 41, age 9.6 ± 3.9 years, 19 female). LQT1, LQT2, and negative responses to epinephrine were obtained in 16, 5, and 20 subjects, respectively. LQTS gene positivity was obtained in two subjects. Beta-blocker therapy was started in all subjects with a positive epinephrine response (n = 21) and in some negative responders because of their strong LQTS phenotype (n = 10). No therapy was given to the subset with less convincing features of LQTS who had also responded negatively to epinephrine (n = 10). Follow-up for 3.0 ± 2 years was uneventful in both management groups. Due to the discordance with genotyping, the epinephrine test cannot be used to diagnose genotype-positive LQTS but when used in combination with phenotype assessment and genetic screening, it could enable better management decisions
