IntroductionUp to half of all women diagnosed with gestational diabetes mellitus develop type 2 diabetes within 5 years after delivery. Metformin is effective in preventing type 2 diabetes in high-risk non-pregnant individuals, but its effect when commenced in the postnatal period is not known. We plan to assess the feasibility of evaluating metformin versus placebo in minimising the risk of dysglycaemia including type 2 diabetes after delivery in postnatal women with a history of gestational diabetes through a randomised trial.Methods and analysisOptimising health outcomes with Metformin to prevent diAbetes After pregnancy (OMAhA) is a multicentre placebo-controlled double-blind randomised feasibility trial, where we will randomly allocate 160 postnatal women with gestational diabetes treated with medication to either metformin (intervention) or placebo (control) tablets to be taken until 1 year after delivery. The primary outcomes are rates of recruitment, randomisation, adherence and attrition. The secondary outcomes are maternal dysglycaemia, cost and quality of life outcomes in both arms, and acceptability of the study and intervention, which will be evaluated through a nested qualitative study. Feasibility outcomes will be summarised using descriptive statistics, point estimates and 95% CIs.Ethics and disseminationThe OMAhA study received ethics approval from the London-Brent Research Ethics Committee (18/LO/0505). Trial findings will be published in a peer-reviewed journal, disseminated at conferences, through our Patient and Public Involvement advisory group (Katie’s Team) and through social media platforms.Trial registration numberISRCTN20930880

IntroductionWomen with gestational diabetes are at increased risk of developing type 2 diabetes later in life. In at-risk general populations, Mediterranean-style diet helps prevent type 2 diabetes. But its effect on postnatal women with a history of gestational diabetes is not known. Prior to a full-scale trial on Mediterranean-style diet in the postnatal period to prevent type 2 diabetes, a feasibility study is required to assess the acceptability of the diet and evaluate the trial processes.Methods and analysisMEditerranean diet for pReventIon of type 2 diabeTes is a single-arm feasibility study (65 women) with qualitative evaluation of women who have recently given birth and had gestational diabetes. The intervention is a Mediterranean-style diet supplemented with nuts and olive oil, with dietary advice and an action plan. A dedicated Health Coach will interact with participants through an interactive lifestyle App. Women will follow the intervention from 6 to 13 weeks post partum until 1 year post partum. The primary outcomes are rates of recruitment, follow-up, adherence and attrition. The secondary outcomes are maternal dysglycaemia, cost and quality of life outcomes, and acceptability of the intervention to participants, and to healthcare professionals delivering the intervention. Feasibility outcomes will be reported using descriptive statistics.Ethics and disseminationEthical approval was obtained through the South Central—Berkshire Research Ethics Committee (19/SC/0064). Study findings will be disseminated via publication in peer-reviewed journals, as well as via newsletters made available to participants and members of Katie’s Team (a women’s health patient and public advisory group).Trial registration numberISRCTN40582975.

Purpose/methods This systematic review aims to provide an overview of strategies available for healthcare professionals (HCPs) to effectively communicate unexpected news in pregnancy, specifically for the most common pregnancy complications. Three medical databases and grey literature were searched until March 2023 using subject headings and keywords. Snowball techniques were also used. The articles were reviewed at each stage of screening independently by two separate authors. Qualitative, quantitative and mixed methods studies were included. Recent findings Forty-three studies were included and grouped according to the gestational age of the pregnancy complication – miscarriage, increased risk screening, foetal conditions, stillbirth. The main key points for communication were outlined at each specific complication and eventually the six common themes that emerged from all the categories were included in the acronym PRICES (Preparation – Referral – Individualized care – Clarity – Empowerment – Sensitivity). Summary Given the negative impact of failed communications both in pregnancy outcomes and patients’ experience, we advocate that communication training for HCP providing pregnancy care should be mandatory, and skills should be updated at regular intervals. Tools like our acronym PRICES can be used during teaching HCPs how to communicate more effectively.
