Project description:ObjectivesTo identify research priorities and explore potential methodologies to inform care in subsequent pregnancies following a stillbirth.DesignWeb-based survey by invitation.ParticipantsMultidisciplinary panel of 79 individuals involved in stillbirth research, clinical practice and/or advocacy from the international stillbirth research community (response rate=64%).Outcome measuresImportance of 16 candidate research topics and perceived utility and appropriateness of randomised controlled trial (RCT) methodology for the evaluation of four pertinent interventions: (1) medical therapies for placental dysfunction (eg, antiplatelet agents); (2) additional antepartum fetal surveillance (eg, ultrasound scans); (3) early planned birth from 37 weeks' gestation and (4) different forms of psychosocial support for parents and families.ResultsCandidate research topics that were rated as 'important and urgent' by the greatest proportion of participants were: medical therapies for placental dysfunction (81%); additional antepartum fetal surveillance (80%); the development of a core outcomes dataset for stillbirth research (79%); targeted antenatal interventions for women who have risk factors (79%) and calculating the risk of recurrent stillbirth according to specific causes of index stillbirth (79%). Whether RCT methodologies were considered appropriate for the four selected interventions varied depending on the criterion being assessed. For example, while 72% of respondents felt that RCTs were 'the best way' to evaluate medical therapies for placental dysfunction, fewer respondents (63%) deemed RCTs ethical in this context, and approximately only half (52%) felt that such RCTs were feasible. There was considerably less support for RCT methodology for the evaluation of different forms of psychosocial support, which was reinforced by free-text comments.ConclusionsFive priority research topics to inform care in pregnancies after stillbirth were identified. There was support for RCTs in this area, but the panel remained divided on the ethics and feasibility of such trials. Engagement with parents and families is a critical next step.

Project description:BackgroundAround 1 in 150 babies are stillborn or die in the first month of life in the UK. Most women conceive again, and subsequent pregnancies are often characterised by feelings of stress and anxiety, persisting beyond the birth. Psychological distress increases the risk of poor pregnancy outcomes and longer-term parenting difficulties. Appropriate emotional support in subsequent pregnancies is key to ensure the wellbeing of women and families. Substantial variability in existing care has been reported, including fragmentation and poor communication. A new care package improving midwifery continuity and access to emotional support during subsequent pregnancy could improve outcomes. However, no study has assessed the feasibility of a full-scale trial to test effectiveness in improving outcomes and cost-effectiveness for the National Health Service (NHS).MethodsA prospective, mixed-methods pre-and post-cohort study, in two Northwest England Maternity Units. Thirty-eight women, (≤ 20 weeks' gestation, with a previous stillbirth, or neonatal death) were offered the study intervention (allocation of a named midwife care coordinator and access to group and online support). Sixteen women receiving usual care were recruited in the 6 months preceding implementation of the intervention. Outcome data were collected at 2 antenatal and 1 postnatal visit(s). Qualitative interviews captured experiences of care and research processes with women (n = 20), partners (n = 5), and midwives (n = 8).ResultsOverall recruitment was 90% of target, and 77% of women completed the study. A diverse sample reflected the local population, but non-English speaking was a barrier to participation. Study processes and data collection methods were acceptable. Those who received increased midwifery continuity valued the relationship with the care coordinator and perceived positive impacts on pregnancy experiences. However, the anticipated increase in antenatal continuity for direct midwife contacts was not observed for the intervention group. Take-up of in-person support groups was also limited.ConclusionsWomen and partners welcomed the opportunity to participate in research. Continuity of midwifery care was supported as a beneficial strategy to improve care and support in pregnancy after the death of a baby by both parents and professionals. Important barriers to implementation included changes in leadership, service pressures and competing priorities.Trial registrationISRCTN17447733 first registration 13/02/2018.

Project description:OBJECTIVE:Pregnancies complicated by gestational diabetes mellitus (GDM) or preexisting diabetes mellitus (DM) are at high risk for adverse newborn outcomes. Whether GDM history, recurrence, or transition to DM modifies such risks is unknown. STUDY DESIGN:Medical record data on 62,013 repeat singleton pregnancies were collected retrospectively from women who delivered at least twice in Utah (2002 through 2010). Poisson regression models with robust variance estimators were used to estimate relative risks (RR) and 95% confidence intervals (CI) associated with GDM/DM status at the previous and/or current pregnancy relative to those without GDM/DM at either. Large for gestational age (LGA), shoulder dystocia, preterm birth (<37 weeks), respiratory distress syndrome, and other neonatal morbidities were examined adjusting for study site, maternal age, race, parity, interpregnancy interval, prepregnancy body mass index, and smoking status. RESULTS:GDM in the previous pregnancy alone increased the risk of LGA in the current pregnancy (RR, 1.20; 95% CI, 1.05-1.38). Recurrent GDM increased the risks of LGA (RR, 1.76; 95% CI, 1.56-1.98), shoulder dystocia (RR, 1.98; 95% CI, 1.46-2.70), and preterm birth (RR, 1.68; 95% CI, 1.44-1.96) beyond that observed for pregnancies with current GDM alone. Women with GDM in a previous pregnancy that transitioned to DM in the current pregnancy and women with DM prior to the previous pregnancy had increased risks of all above outcomes. CONCLUSION:GDM in a previous pregnancy alone without recurrence may still confer an increased LGA risk. Pregnancies complicated by GDM that transition to DM and those with DM prior to the previous pregnancy have the highest risks of adverse newborn outcomes.

Project description:ObjectivesTo assess the risk of recurrence of cervical artery dissection (CAD) during pregnancy and puerperium in women with a history of CAD and then help physicians with providing medical information to women who wish to become pregnant.MethodsWomen aged 16-45 years who were admitted to our center for a CAD between 2005 and 2017 were identified from the hospital database, and those with spontaneous and symptomatic CAD were included. They were then contacted to answer a questionnaire that was specifically designed in regard to the recurrence of CAD and pregnancies after the primary CAD.ResultsNinety-one patients satisfied our inclusion criteria, and 89 were included in the analysis. During a median follow-up of 7.0 years, 4 women (4.4%) had recurrent CAD, although none during pregnancy or puerperium. Eighteen women (20%) had a total of 20 full-term pregnancies, occurring at least 6 months after CAD. Of these 20 pregnancies, 13 (65%) were vaginal deliveries, and 7 (35%) were cesarean sections. The reason for the absence of pregnancies after the initial CAD was unrelated to the vascular event in 89% of cases, but 8% of the women had been advised by a physician to avoid any future pregnancy or they had been recommended to undergo abortion or sterilization.ConclusionIn this study, there were no CAD recurrences during subsequent pregnancies or postpartum, irrespective of the type of delivery. Thus, pregnancy after a history of CAD appears to be safe.

Project description:BackgroundAt present, individualized interventions can be given to patients with a clear etiology of pregnancy loss to improve the subsequent pregnancy outcomes, but the current reproductive status of the patient cannot be changed. The aim of this study was to investigate the association between female reproductive status and subsequence pregnancy outcome in patients with prior pregnancy loss (PL).MethodsA prospective, dynamic population cohort study was carried out at the Second Hospital of Lanzhou University. From September 2019 to February 2022, a total of 1955 women with at least one previous PL were enrolled. Maternal reproductive status and subsequent reproductive outcomes were recorded through an electronic medical record system and follow-up. Logistic regression was used to evaluate the association between reproductive status and the risk of subsequent reproductive outcomes.ResultsAmong all patients, the rates of subsequent infertility, early PL, late PL, and live birth were 20.82%, 24.33%, 1.69% and 50.77% respectively. In logistic regression, we found that age (OR 1.08, 95% CI 1.04-1.13) and previous cesarean delivery history (OR 2.46, 95% CI 1.27-4.76) were risk factors for subsequent infertility in patients with PL. Age (OR 1.06, 95% CI 1.03-1.10), age at first pregnancy (OR 1.06, 95% CI 1.03-1.10), BMI (OR 1.06, 95% CI 1.02-1.11), previous PL numbers (OR 1.18, 95% CI 1.04-1.57) and without pre-pregnancy intervention (OR 1.77, 95% CI 1.35-2.24) were risk factors for non-live birth. Age (OR 1.06, 95% CI 1.03-1.09), age at first pregnancy (OR 1.06, 95% CI 1.02-1.09), BMI (OR 1.07, 95% CI 1.02-1.11), previous PL numbers (OR 1.15, 95% CI 1.02-1.31) and without pre-pregnancy intervention (OR 2.16, 95% CI 1.65-2.84) were risk factors for PL.ConclusionsThe reproductive status of people with PL is strongly correlated with the outcome of subsequent pregnancies. Active pre-pregnancy intervention can improve the subsequent pregnancy outcome.Trial registrationThis study was registered in the Chinese Clinical Trial Registry with the registration number of ChiCTR2000039414 (27/10/2020).

Project description:BackgroundAntepartum stillbirth, i.e., intrauterine fetal death (IUFD) above 24 weeks of gestation, occurs with a prevalence of 2.4-3.1 per 1000 live births in Central Europe. In order to ensure highest standards of treatment and identify causative and associated (risk) factors for fetal death, evidence-based guidelines on clinical practice in such events are recommended. Owing to a lack of a national guideline on maternal care and investigations following stillbirth, we, hereby, sought to assess the use of institutional guidelines and clinical practice after IUFD in Austrian maternity units.MethodsA national survey with a paper-based 12-item questionnaire covering demographic variables, local facilities and practice, obstetrical care and routine post-mortem work-up following IUFD was performed among all Austrian secondary and tertiary referral hospitals with maternity units (n = 75) between January and July 2019. Statistical tests were conducted using Chi2 and Fisher's Exact test, respectively. Univariate logistic regression analyses were performed to calculate odds ratio (OR) with a 95% confidence interval (CI).Results46 (61.3%) obstetrical departments [37 (80.4%) secondary; 9 (19.6%) tertiary referral hospitals] participated in this survey, of which 17 (37.0%) have implemented an institutional guideline. The three most common investigations always conducted following stillbirth are placental histology (20.9%), fetal autopsy (13.1%) and maternal antibody screen (11.5%). Availability of an institutional guideline was not significantly associated with type of hospital, on-site pathology department, or institutional annual live and stillbirth rates. Post-mortem consultations only in cases of abnormal investigations following stillbirth were associated with lower odds for presence of such guideline [OR 0.133 (95% CI 0.018-0.978); p = 0.047]. 26 (56.5%) departments consider a national guideline necessary.ConclusionsLess than half of the surveyed maternity units have implemented an institutional guideline on maternal care and investigations following antepartum stillbirth, independent of annual live and stillbirth rate or type of referral centre.

Project description:BackgroundPregnant women who have undergone pregnancy loss often display both posttraumatic stress (PTS) and posttraumatic growth (PTG). However, the precise relationship and structure of symptomatic levels of PTS and PTG have not been well understood. This study aimed to assess the associations between PTS and PTG symptoms in women during subsequent pregnancies following a previous pregnancy loss.MethodsA total of 406 pregnant women with a history of pregnancy loss were included in this study. The Impact of Events Scale-6 (IES-6) and the Posttraumatic Growth Inventory Short Form (PTGI-SF) were used to assess symptoms of PTS and PTG, respectively. The Graphical Gaussian Model was employed to estimate the network model. Central symptoms and bridge symptoms were identified based on "expected influence" and "bridge expected influence" indices, respectively. The stability and accuracy of the network were examined using the case-dropping procedure and nonparametric bootstrapped procedure.ResultsThe network analysis identified PTG3 ("Ability to do better things") as the most central symptom, followed by PTS3 ("Avoidance of thoughts") and PTG6 ("New path for life") in the sample. Additionally, PTS3 ("Avoidance of thoughts") and PTG9 ("Perception of greater personal strength") were bridge symptoms linking PTS and PTG clusters. The network structure was robust in stability and accuracy tests.ConclusionsInterventions targeting the central symptoms identified, along with key bridge symptoms, have the potential to alleviate the severity of PTS experienced by women with a history of pregnancy loss and promote their personal growth.

Project description:BackgroundThere are limited data describing adverse infant outcomes in infants born to women with a low risk of complications during pregnancy, such as those who may be enrolled in maternal immunization trials. This retrospective study estimated incidence proportions of infant outcomes in different cohorts of liveborn infants in England between 2005 and 2017.MethodsThe incidence proportions of 10 infant outcomes were calculated for liveborn infants from pregnancies represented in the Clinical Practice Research Datalink (CPRD) Mother-Baby Link (MBL) and linkage to Hospital Episode Statistics (HES). Three infant cohorts were designed: (1) the all pregnancies infants cohort (N = 185,119), (2) the all pregnancies with a gestational age (GA) ≥ 24 weeks infants cohort (N = 183,869), and (3) the low-risk pregnancies infants cohort (LR infants cohort, N = 121,871), which included pregnancies with a GA ≥ 24 weeks and no diagnosis of predefined high-risk medical conditions until 24 weeks GA.ResultsThe most common adverse infant outcome in the three infant cohorts was macrosomia (e.g., 1,085.9/10,000 live births in the LR infants cohort), followed by minor congenital anomalies (e.g., 800.6/10,000 in the LR infants cohort), very low/low birth weight (e.g., 400.6/10,000 in the LR infants cohort), and major congenital anomalies (e.g., 270.4/10,000 in the LR infants cohort). The incidence proportions for early-onset sepsis, very low/low birth weight, and minor and major congenital anomalies were lower in the LR infants than in the other cohorts (non-overlapping confidence intervals [CIs]). The incidence proportions of neonatal death, infant death, late-onset sepsis, macrosomia, small for GA, and large for GA were similar between cohorts (overlapping CIs).ConclusionsThis study generated background rates of adverse infant outcomes from liveborn infants of all and low-risk pregnancies represented in the CPRD Pregnancy Register MBL and linkage to HES. The results indicate lower incidence proportions of several adverse infant outcomes in infants from low-risk pregnancies compared to all pregnancies, illustrating the importance of considering maternal risk factors. These background rates may facilitate the interpretation of safety data from maternal immunization trials and of pharmacovigilance data from maternal vaccines. They may also be of interest for other interventions studied in pregnant women.

Project description:Physical synchrony has been suggested to have positive effects on not only concurrent but also subsequent communication, but the underlying neural processes are unclear. Using functional near-infrared spectroscopy (fNIRS) hyperscanning, we tested the effects of preceding physical synchrony on subsequent dyadic teaching-learning communication. Thirty-two pairs of participants performed two experimental sessions. In each session, they underwent a rhythmic arm movement block with synchronous or asynchronous conditions, and then taught/learned unknown words to/from each other according to a given scenario. Neural activities in their medial and left lateral prefrontal cortex (PFC) were measured and inter-brain synchronization (IBS) during the teaching-learning blocks was evaluated. Participants rated their subjective rapport during the teaching-learning blocks, and took a word memory test. The analyses revealed that (1) prior physical synchrony enhanced teacher-learner rapport; (2) prior physical synchrony also enhanced IBS in the lateral PFC; and (3) IBS changes correlated positively with rapport changes. Physical synchrony did however not affect word memory performance. These results suggest that IBS can be useful to measure the effects of social-bonding facilitation activities for educational communication.

Project description:BACKGROUND:Increasing rates of postpartum haemorrhage and obstetric transfusion mean that more women are entering subsequent pregnancies with a history of blood transfusion. This study investigates subsequent pregnancy outcomes of women with a prior obstetric red cell transfusion, compared to women without a transfusion. METHODS:All women with a first pregnancy resulting in a liveborn singleton infant of at least 20 weeks gestation delivering in hospitals in New South Wales, Australia, between 2003 and 2012 were included in the study, with followup for second births until June 2015. Linked hospital and births data were used to identify women with a transfusion and/or postpartum haemorrhage in their first birth, time to second pregnancy and adverse birth outcomes (including transfusion, postpartum haemorrhage and severe morbidity) in their subsequent birth. RESULTS:There were 358,384 singleton births to primiparous women, with 1.4% receiving an obstetric blood transfusion. Sixty-three percent of women had at least one subsequent birth. The relative risk (RR) of requiring a transfusion in a second birth was 4.9 (95% CI 4.1,6.1) for women with a previous transfusion compared with women without. The risk (RR) of severe morbidity in a second birth was 4.1 times higher (95% CI 2.2,7.4) for those receiving a transfusion without haemorrhage in their first birth compared with women with neither haemorrhage nor transfusion. CONCLUSION:It is important to consider a woman's history of transfusion and/or haemorrhage as part of her obstetric history to ensure management in a manner that minimises risk in subsequent pregnancies.
