Aim: The aim of the study was to determine the acceptability and feasibility of an intervention to support women with mild to moderate anxiety in pregnancy.Design: The intervention development and feasibility testing followed the MRC guidelines for complex interventions. A feasibility study was conducted between April - May 2016.Methods: Qualitative and quantitative data were collected to assess the acceptability and feasibility of the intervention. The intervention was delivered in three components: pre-group individual meeting with the midwife; group sessions; guided self-help resources. The intervention was facilitated by midwives and co-facilitated by midwifery support workersResults: Eight women with self-reported symptoms of mild to moderate anxiety participated in the study. Women reported an improvement in anxiety symptoms and felt they had benefitted from participation. Accessing social support from other women in similar circumstances had helped women to feel less isolated and facilitated open and honest discussions. Women valued the involvement of the midwife facilitator to support their wellbeing and provide specific advice about their pregnancies.Conclusions: The intervention design appeared to be acceptable and beneficial for this group of women. This study highlights the potential for midwives to facilitate supportive interventions to enhance the current provision of emotional support for women with anxiety symptoms in pregnancy and address the current gap in services. The intervention is potentially feasible for introduction into current clinical practice with minimal additional resources.

We have deduced the emission probability of the 447-keV γ ray from the ɛ+β+ decay of 137Ceg (9.0 h) relative to that of the 254-keV γ ray from the 137Cem (34.4 h) decay in transient equilibrium. The time-dependent factor in transient equilibrium was applied following the Bateman equation for a radioactive decay chain. The isotope was produced via the 139La(p,3n)137Cem,g reaction by bombarding natLa with a proton beam from the 88-in. cyclotron at Lawrence Berkeley National Laboratory. γ-ray intensities were measured using an HPGe detector. The emission probability for the 447-keV γ ray deduced in this work is 1.21(3) (that is 1.21 ± 0.03) per hundred parent decays, which differs significantly from an earlier published value of 2.24(10). We identify the source of this discrepancy to be an incorrect use of the time-dependent factor. Additionally, we have deduced the emission probability of the 504-keV γ ray from the decay of 85Yg (2.68 h) relative to that of the 232-keV γ ray from the 85Srm (1.127 h) decay in transient equilibrium. The isotope was produced via the 86Sr(p,2n)85Yg reaction by bombarding 86SrCO3 with a proton beam at the same facility. The study confirms the assumption of the time-dependent correction for recommending the emission probability of the 504-keV γ ray in the literature. Our work highlights the importance of explicit description by authors of any time-dependent correction they have made when reporting γ-ray intensities for nuclides in transient equilibrium. The need and significance of accurate and precise decay data of 137Ceg and 85Yg in basic science and medicine is briefly outlined.
