Background: Gestational diabetes mellitus (GDM) affects 1-in-7 pregnancies globally and is associated with significant short- and long-term health consequences. Although health behaviour change interventions can effectively reduce these risks, a significant implementation gap exists in translating this evidence into routine practice. Bump2Baby and Me (B2B&Me) was a mobile health (mHealth) coaching intervention provided to women at-risk of GDM from early pregnancy through to 1-year postpartum. B2B&Me Plus (B2B&Me+) aims to refine, implement and evaluate the implementation of this personalised intervention across 4 countries (Ireland, Spain, Poland and Norway) with differing health systems and population profiles. Methods: This study employs a hybrid type 3 implementation-effectiveness design using a non-randomised ABA block approach within a longitudinal cohort. Participants will be screened using the Monash machine learning GDM screening tool (MMLGDST). During the intervention (Block B), women at risk of developing GDM will be offered access to a smartphone-based coaching application featuring 1:1 synchronous sessions, asynchronous text and video messaging along with a Bluetooth-enabled weighing scale for self-monitoring. Support continues from early pregnancy through to nine months postpartum. The study’s primary objective is to evaluate reach, adoption, implementation and maintenance of the B2B&Me+ intervention programme when delivered within routine maternity care. Implementation success will be assessed using the RE-AIM framework, while secondary outcomes will assess intervention effectiveness. The study will examine population-level uptake at each site, evaluate the benefits and costs of implementation across varying contexts, and analyse how four different referral methods, randomised at the site level, affect uptake. In addition, a European implementation toolkit will be developed to provide health services with scalable strategies to bridge the evidence-to-practice gap. Discussion: This study will contribute to a growing literature on the implementation of a successfully trialled mHealth intervention in a real-world context. Understanding variation in both intervention and implementation success within a routine maternity care context across diverse settings will inform the development of an implementation toolkit to support health services in reducing the incidence of GDM and improving maternal and child health outcomes.

This study was registered with ClinicalTrials.gov ( NCT07189221 ) on 28 August 2025 ( https://clinicaltrials.gov/study/NCT07189221?cond=diabetes ) Contributions to the literature: B2B&Me+ is the first multi-site European study testing how a mobile health coaching programme for women at-risk of gestational diabetes can be delivered within routine maternity care across four countries. The study tests four strategies for inviting women to join the programme, with the intent to identify which strategy most effectively reaches and engages them in practice. Using established implementation science frameworks, B2B&Me+ examines what drives or hinders delivery across four diverse European health systems, generating evidence applicable beyond the study settings. Findings will directly inform a practical European toolkit to support maternity services in adopting the programme at scale.

Background: The sFlt-1/PlGF ratio has proven predictive value in diagnosing preeclampsia. Referring to a study from 18 American perinatal centers, we present results from 2 European centers showing the significant value of those markers in predicting severe perinatal outcomes in hypertensive disorders of pregnancy. Methods: A total of 1630 patients with suspected or confirmed placental insufficiency, hospitalized in two tertiary perinatal centers in Poland and Macedonia, were assessed for their sFlt-1/PlGF ratio. Due to incomplete data, perinatal outcomes were only obtained for 1196 patients. They were sorted into two groups according to the value of the sFlt-1/PlGF ratio (p < 0.001). In a group of patients with an index value of ≥40, the AUC was 0.9955 (95% CI: 0.9913 to 0.9996), with a sensitivity of 52%, a specificity of 78%, a positive predictive value of 77%, and a negative predictive value of 53%. For patients who were tested before 37 weeks of gestation, 66% of women with a ratio of ≥40 delivered within 7 days of the test, and 80% of those with a ratio of <40 delivered more than 7 days after the test, with a sensitivity of 68%, a specificity of 79%, a positive predictive value of 66%, and a negative predictive value of 80%. Conclusions: In women with hypertensive disorders, the sFlt-1/PlGF ratio can be used to predict the time to delivery. A cut-off of 40 is very useful in predicting severe perinatal outcomes.

Background: Nowadays, it is possible to identify a group at increased risk of preeclampsia (PE) and fetal growth restriction (FGR) using the principles of the Fetal Medicine Foundation (FMF). It has been established for several years that acetylsalicylic acid (ASA) reduces the incidence of PE and FGR in high-risk populations. This study aimed to evaluate the implementation of ASA use after the first-trimester screening in a Polish population without chronic hypertension, as well as its impact on perinatal complications. Material and methods: A total of 874 patients were enrolled in the study during the first-trimester ultrasound examination. The risk of PE and FGR was assessed according to the FMF guidelines, which include the maternal history, mean arterial pressure (MAP), uterine artery pulsatility index (UtPI), pregnancy-associated plasma protein A (PAPP-A) and placental growth factor (PLGF). Among patients with a risk higher than >1:100, ASA was administered at a dose of 150 mg. Perinatal outcomes were assessed among the different groups. Results: When comparing women in the high-risk group with those in the low-risk group, a statistically significantly higher risk of pregnancy complications was observed in the high-risk group. These complications included pregnancy-induced hypertension (PIH) (OR 3.6 (1.9–7)), any PE (OR 7.8 (3–20)), late-onset PE (OR 8.5 (3.3–22.4)), FGR or small for gestational age (SGA) (OR 4.8 (2.5–9.2)), and gestational diabetes mellitus type 1 (GDM1) (OR 2.4 (1.4–4.2)). The pregnancies in the high-risk group were more likely to end with a cesarean section (OR 1.9 (1.2–3.1)), while the newborns had significantly lower weights (<10 pc (OR 2.9 (1.2–6.9)), <3 pc (OR 10.2 (2.5–41.7))). Conclusions: The first-trimester screening test for PE and FGR is a necessary and effective tool in identifying high-risk pregnancies. ASA prophylaxis among high-risk patients may have the most beneficial effect. Furthermore, this screening tool may significantly reduce the incidence of early-onset PE (eo-PE).

Preeclampsia (PE) is a multi-factorial disorder of pregnancy, and it continues to be one of the leading causes of fetal and maternal morbidity and mortality worldwide. Aspirin is universally recommended for high-risk women to reduce preeclampsia risk. The purpose of this review is to summarize the recommendations of various scientific societies on predicting preeclampsia and their indications for the inclusion of acetylsalicylic acid (ASA) prophylaxis. Fourteen guidelines were compared. The recommended dose, screening method, and gestational age at the start of the test vary depending on the recommendation. The societies are inclined to recommend using increasingly higher doses (>75 mg) of ASA, with many encouraging doses from 100 mg upward. Most societies indicate that the optimal time for implementing aspirin is prior to 16 weeks’ gestation. Following the publication of the Aspirin for Evidence-Based Preeclampsia Prevention (ASPRE) trial results and other papers evaluating the Fetal Medicine Foundation (FMF) screening model, a large number of societies have changed their recommendations from those based on risk factors alone to the ones based on the risk assessment proposed by the FMF. This allows for the detection of a high-risk pregnancy population in whom aspirin will be remarkably effective in preventing preterm PE, thereby decreasing maternal and fetal morbidity.

(1) Despite its high prevalence, the diagnostic delay of endometriosis is still estimated to be about 7 years. The objective of the present study is to understand the symptomatology of endometriosis in patients across various countries and to assess whether the severity of symptoms correlates with the diagnosed stage of disease. (2) An international online survey collected self-reported responses from 2964 participants from 59 countries. Finalization of the questionnaire and its distribution was achieved by cooperation with various organizations and centers around the globe. (3) Chronic pain presentation remarkably increased between Stage 1 and 2 (16.2% and 32.2%, respectively). The prevalence of pain only around and during menstruation was negatively correlated to the stage, presenting with 15.4% and 6.9% in Stages 1 and 4, respectively. Atypical presentation of pain was most commonly reported in stage 4 (11.4%). Pain related solely to triggering factors was the most uncommon presentation of pain (3.2%). (4) Characteristics of pain and quality of life tend to differ depending on the reported stage of the endometriosis. Further research may allow a better stage estimation and identification of patients with alarming symptomatic presentation indicative of a progressive stage, even those that are not yet laparoscopically diagnosed.
