RESUMEN
BACKGROUND: Globally, midwifery-led birthing units are associated with favourable clinical outcomes and positive birth experiences. As part of our evaluation of Canada's first Alongside Midwifery Unit (AMU) at Markham Stouffville Hospital, we sought to explore and compare birth experiences and satisfaction among midwifery clients who gave birth on the AMU with midwifery clients who gave birth on the traditional obstetric unit prior to AMU implementation. METHODS: We conducted a structured, online, cross-sectional survey of midwifery clients in the six months before, and up to 18 months after, opening of the AMU at Markham Stouffville Hospital, Ontario Canada. The survey contained validated measures of satisfaction including personal capacity and participation; perceived safety, control, and security; professional support; and satisfaction. Descriptive statistics and tests of significance were completed in SPSS. RESULTS: A total of 193 responses were included in our analyses (pre-AMU n = 47, post-AMU n = 146). All participants had positive experiences in the four domains assessed. Compared to those who gave birth with midwives on the Labour unit, those who gave birth on the AMU indicated more positive experiences for some measures. Perceptions pertaining to being an active participant in care, to security and sense of control were more positive among those who gave birth on the AMU. CONCLUSION: The AMU in Ontario is associated with high levels of satisfaction during birth, particularly the perception of being actively engaged in decision making, having a sense of control and safety, and having confidence in the care provider team. Care received on the AMU does not compromise birth experiences or satisfaction and may be associated with greater autonomy and agency for the person giving birth.

OBJECTIVE: To determine the impact of prior gestational diabetes mellitus (GDM) on perinatal outcomes in a subsequent GDM pregnancy. METHODS: This retrospective cohort study included 544 multiparous patients with two consecutive pregnancies between 2012-2019, where the second (index) pregnancy was affected by GDM. The primary exposure was prior GDM diagnosis, categorized into medical and dietary management. The primary outcome was a composite including need for pharmacotherapy, large-for-gestational age, or neonatal hypoglycemia. Adjusted odds ratios (aOR) were calculated using multivariable logistic regression controlling for maternal age, pre-pregnancy body mass index, and gestational age at GDM diagnosis in the index pregnancy. RESULTS: Of the 544 patients, 164 (30.1%) had prior GDM. Prior GDM significantly increased the likelihood of composite outcome compared to no prior GDM (74.4% vs. 57.4%; P < 0.001). After adjusting for confounders, prior GDM remained significantly associated with the composite outcome (aOR 2.03, 95% confidence interval [CI] 1.31-3.15). Stratifying by prior GDM treatment modality, a significant association was found for prior pharmacotherapy-controlled GDM (aOR 3.29, 95% CI 1.64-6.59), but not for prior diet-controlled GDM (aOR = 1.54, 95% CI 0.92-2.60). CONCLUSION: A history of pharmacotherapy-controlled GDM in a previous pregnancy increases odds of adverse perinatal outcomes in a subsequent GDM pregnancy.
RESUMEN
Introduction: Point of Care Ultrasound (POCUS) is used globally in obstetrics to conduct real time bedside ultrasound scans to answer a clinical question, and it may be conducted by a non-sonography healthcare practitioner. The College of Midwives of Ontario expanded the scope of practice in 2018 to allow registered midwives to perform POCUS during clinical assessments. In response, a POCUS training curriculum for practicing midwives was developed. This paper reports on the perceptions of learners about the impact of this training on their clinical practice. Methods: We conducted a mixed-methods study to understand learner perceptions. Data collection included surveys at four time points over a year, and semi-structured interviews. Quantitative data were analyzed through descriptive statistics, and qualitative analyses used a constructivist approach to grounded theory. Results: The frequency of POCUS use within antenatal care increased among learners, with common applications including assessment of fetal presentation and confirmation of viability. POCUS was seen to holistically aid practitioners care by providing additional skills and knowledge to improve care quality and access to care, particularly for remote areas where ultrasounds are not easily available. However, participants articulated a need for clearer regulatory guidelines outlining how this technology should be applied in midwifery. Equipment purchasing and maintaining costs were a barrier for many midwives. Conclusions: Participants who had access to a device are continuing to use sonography within their clinics to provide comprehensive midwifery care informed by real-time ultrasound assessments. POCUS scans were seen to offer many benefits to improve patient care.
RESUMEN
Gestational diabetes mellitus (GDM) is associated with adverse health outcomes for the pregnant individual and their baby. Screening approaches for GDM have undergone several iterations, introducing variability in practice among healthcare providers. As such, our study aimed to explore the views of antenatal providers regarding their practices of, and counseling experiences on the topic of, GDM screening in Ontario. We conducted a qualitative, grounded theory study. The study population included antenatal providers (midwives, family physicians, and obstetricians) practicing in Hamilton, Ottawa, or Sudbury, Ontario. Semi-structured telephone interviews were conducted and transcribed verbatim. Transcripts were analyzed using inductive coding upon which codes, categories, and themes were developed to generate a theory grounded in the data. Twenty-two participants were interviewed. Using the social-ecological theory, we created a model outlining four contextual levels that shaped the experiences of GDM counseling and screening: Intrapersonal factors included beliefs, knowledge, and skills; interpersonal factors characterized the patient-provider interactions; organizational strengths and challenges shaped collaboration and health services infrastructure; and finally, guidelines and policies were identified as systemic barriers to health care access and delivery. A focus on patient-centered care was a guiding principle for all care providers and permeated all four levels of the model. Patient-centered care and close attention to barriers and facilitators across intrapersonal, interpersonal, organizational, and policy domains can minimize the impact of variations in GDM screening guidelines. Among care providers, there is a desire for additional skill development related to GDM counseling, and for national consensus on optimal screening guidelines.
RESUMEN
BACKGROUND: Many of the adverse outcomes of gestational diabetes mellitus (GDM) are linked to excessive fetal growth, which is strongly mediated by the adequacy of maternal glycemic management. The COVID-19 pandemic led to a rapid adoption of virtual care models. We aimed to compare glycemic management, fetal growth, and perinatal outcomes before and during the COVID-19 pandemic. METHODS: A retrospective cohort study was conducted between 2017 and 2020. Singleton pregnancies complicated by GDM were included in the study. The cohort was stratified into "before" and "during" COVID-19 subgroups, using March 11, 2020, as the demarcation time point. Women who began their GDM follow-up starting March 11, 2020, and thereafter were allocated to the COVID-19 era, whereas women who delivered before the demarcation point served as the pre-COVID-19 era. The primary outcome was the rate of large-for-gestational-age (LGA) neonates. Secondary outcomes included select maternal and neonatal adverse outcomes. RESULTS: Seven hundred seventy-five women were included in the analysis, of which 187 (24.13%) were followed during the COVID-19 era and 588 (75.87%) before the COVID-19 era. One hundred seventy-one of the 187 women (91.44%) followed during COVID-19 had at least 1 virtual follow-up visit. No virtual follow-up visits occurred before the COVID-19 era. There was no difference in the rate of LGA neonates between groups on both univariate (5.90% vs 7.30%, p=0.5) and multivariate analyses, controlling for age, ethnicity, parity, body mass index, gestational weight gain, chronic hypertension, smoking, and hypertensive disorders in pregnancy (adjusted odds ratio [aOR] 1.11, 95% confidence interval [CI] 0.49 to 2.51, p=0.80). In the multivariate analysis, there was no difference in composite neonatal outcome between groups (GDM diet: aOR 1.40, 95% CI 0.81 to 2.43, p=0.23; GDM medical treatment: aOR 1.20, 95% CI 0.63 to 2.43, p=0.5). CONCLUSIONS: After adjusting for differences in baseline variables, the combined virtual mode of care was not associated with a higher rate of LGA neonates or other adverse perinatal outcomes in women with GDM. Larger studies are needed to better understand the specific impact of virtual care on less common outcomes in pregnancies with GDM.

BACKGROUND: Maternal serum markers used for trisomy 21 screening are associated with placenta-mediated complications. Recently, there has been a transition from the traditional first-trimester screening (FTS) that included PAPP-A (pregnancy-associated plasma protein-A) and beta-hCG (human chorionic gonadotropin), to the enhanced FTS test, which added first-trimester AFP (alpha-fetoprotein) and PlGF (placental growth factor). However, whether elevated first-trimester AFP has a similar association with placenta-mediated complications to that observed for elevated second-trimester AFP remains unclear. Our objective was to estimate the association of first-trimester AFP with placenta-mediated complications and compare it with the corresponding associations of second-trimester AFP and other first-trimester serum markers. METHODS: Retrospective population-based cohort study of women who underwent trisomy 21 screening in Ontario, Canada (2013-2019). The association of first-trimester AFP with placenta-mediated complications was estimated and compared with that of the traditional serum markers. The primary outcome was a composite of stillbirth or preterm placental complications (preeclampsia, birthweight less than third centile, or placental abruption). RESULTS: A total of 244â 990 and 96â 167 women underwent FTS and enhanced FTS test screening, respectively. All markers were associated with the primary outcome, but the association for elevated first-trimester AFP (adjusted relative risk [aRR], 1.57 [95% CI, 1.37-1.81]) was weaker than that observed for low PAPP-A (aRR, 2.48 [95% CI, 2.2-2.8]), low PlGF (aRR, 2.28 [95% CI, 1.97-2.64]), and elevated second-trimester AFP (aRR, 1.97 [95% CI, 1.81-2.15]). When the models were adjusted for all 4 enhanced FTS test markers, elevated first-trimester AFP was no longer associated with the primary outcome (aRR, 0.77 [95% CI, 0.58-1.02]). CONCLUSIONS: Unlike second-trimester AFP, elevated first-trimester AFP is not an independent risk factor for placenta-mediated complications.

BACKGROUND: Globally, midwifery-led birthing units are associated with excellent maternal and neonatal outcomes, and positive childbirth experiences. However, little is known about what aspects of midwife-led units contribute to favorable experiences and overall satisfaction. Our aim was to explore and describe midwifery service user experiences at Canada's first Alongside Midwifery Unit (AMU). METHODS: We used a qualitative, grounded theory approach using semi-structured interviews with recipients of midwifery care at the AMU. FINDINGS: Data were collected from twenty-eight participants between September 2018 and March 2020. Our generated theory explains how birth experiences and satisfaction were influenced by how well the AMU aligned with expectations or desired experiences related to the following four themes: (1) maintaining the midwifery model of care, (2) emphasizing control and choice, (3) facilitating interprofessional relationships, and (4) appreciating the unique AMU birthing environment. CONCLUSION: Canada's first AMU met or exceeded service-user expectations, resulting in high levels of satisfaction with their birth experience. Maintaining core elements of the midwifery model of care, promoting high levels of autonomy, and facilitating positive interprofessional interactions are crucial elements contributing to childbirth satisfaction in the AMU environment.

OBJECTIVE: To estimate the association of advanced maternal age with pregnancy complications in twin pregnancies and compare it with that observed in singleton pregnancies. METHODS: A population-based retrospective cohort study of all patients with a singleton or twin hospital birth in Ontario, Canada, between 2012 and 2019. The primary outcome was preterm birth (PTB) less than 34 weeks. Pregnancy outcomes were stratified by maternal age groups in twin pregnancies and, separately, in singleton pregnancies. RESULTS: A total of 935 378 patients met the study criteria: 920503 (98.4%) had a singleton pregnancy and 14 875 (1.6%) had twins. In singletons, the rate of PTB less than 34 weeks increased progressively with increasing maternal age and was highest for patients aged 45 years or more (3.4%; adjusted risk ratio [aRR] 1.56, 95% confidence interval [CI] 1.05-2.33). By contrast, in twins, although the rate of PTB less than 34 was highest patients under 20 years of age (25.3%) and was lowest among patients aged 35-39 years (11.7%), the associations between maternal age group and the risk of PTB were not statistically significant in the adjusted analysis. CONCLUSION: Although the absolute rates of pregnancy complications are higher in twin pregnancies, there are considerable differences in the relationship between maternal age and the risk of certain complications between twin and singleton pregnancies.

INTRODUCTION: Gestational diabetes mellitus (GDM) is associated with adverse perinatal outcomes. Approaches to screening for GDM continue to evolve, introducing potential variability of care. This study explored the impact of these variations on GDM counselling and screening from the perspectives of pregnant individuals. METHODS: Following a Corbin and Strauss approach to qualitative, grounded theory we recruited 28 individuals from three cities in Ontario, Canada who had a singleton pregnancy under the care of either a midwife, family physician or obstetrician. Convenience and purposive sampling techniques were used. Semi-structured telephone interviews were conducted and transcribed verbatim between March and December 2020. Transcripts were analysed inductively resulting in codes, categories and themes. RESULTS: Three themes were derived from the data about GDM screening and counselling: 'informing oneself', 'deciding' and 'screening'. All participants, regardless of geographical region, or antenatal care provider, moved through these three steps during the GDM counselling and screening process. Differences in counselling approaches between pregnancy care providers were noted throughout the 'informing' and 'deciding' stages of care. Factors influencing these differences included communication, healthcare autonomy and patient motivation to engage with health services. No differences were noted within care provider groups across the three geographic regions. Participant experiences of GDM screening were influenced by logistical challenges and personal preferences towards testing. CONCLUSION: Informing oneself about GDM may be a crucial step for facilitating decision-making and screening uptake, with an emphasis on information provision to facilitate patient autonomy and motivation. PATIENT OR PUBLIC CONTRIBUTION: Participants of our study included patients and service users. Participants were actively involved in the study design due to the qualitative, patient-centred nature of the research methods employed. Analysis of results was structured according to the emergent themes of the data which were grounded in patient perspectives and experiences.

BACKGROUND: Canada's first alongside midwifery unit (AMU) was intentionally informed by evidence-based birth environment design principals, building on the growing evidence that the built environment can shape experiences, satisfaction, and birth outcomes. OBJECTIVES: To assess the impact of the built environment of the AMU for both service users and midwives. This study aimed to explore the meanings that individuals attribute to the built environment and how the built environment impacted people's experiences. METHODS: We conducted a mixed-methods study using a grounded theory methodology for data collection and analysis. Our research question and data collection tools were underpinned by a sociospatial conceptual approach. All midwives and all those who received midwifery care at the unit were eligible to participate. Data were collected through a structured online survey, interviews, and focus group. RESULTS: Fifty-nine participants completed the survey, and interviews or focus group were completed with 28 service users and 14 midwives. Our findings demonstrate high levels of satisfaction with the birth environment. We developed a theoretical model, where "making space" for midwifery in the hospital contributed to positive birth experiences and overall satisfaction with the built environment. The core elements of this model include creating domestic space in an institutional setting, shifting the technological approach, and shared ownership of the unit. CONCLUSIONS: Our model for creating, shifting, and sharing as a way to make space for midwifery can serve as a template for how intentional design can be used to promote favorable outcomes and user satisfaction.

BACKGROUND: Both gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP) are common, and each are associated with adverse maternal and perinatal outcomes. Midwives may be the first point of care when these conditions arise. This study evaluated the experiences of midwives when providing care to women and people with pregnancies complicated by GDM or HDP. METHODS: A mixed methods study was completed in Ontario, Canada, using a sequential, explanatory approach. A total of 144 online surveys were completed by midwives, followed by 20 semi-structured interviews that were audio recorded and transcribed verbatim. Survey data were analysed using descriptive statistics. Thematic analysis was used to generate codes from the interview data, which were mapped to the Theoretical Domains Framework (TDF), to elucidate factors that might influence management. RESULTS: Most of the midwives' clinical behaviours relating to GDM or HDP were in keeping with guidelines and regulatory standards set by existing provincial standards. Six theoretical domains from the TDF appeared to influence midwives'care pathway: "Internal influences" included knowledge, skills and beliefs about capabilities; while "external influences" included social/professional role and identity, environmental context, and social influences. Interprofessional collaboration emerged as a significant factor on both the internal and external levels of influence. CONCLUSIONS: We identified barriers and facilitators that may improve the experiences of midwives and clients when GDM or HDP newly arises in a pregnancy, necessitating further consultation or management by another health care provider.

CONTEXT: The optimal 50 g-glucose challenge test (GCT) cutoff for the diagnosis of gestational diabetes mellitus (GDM) in twin pregnancies is unknown. OBJECTIVE: This work aimed to explore the screening accuracy of the 50 g-GCT and its correlation with the risk of large for gestational age (LGA) newborn in twin compared to singleton pregnancies. A population-based retrospective cohort study (2007-2017) was conducted in Ontario, Canada. Participants included patients with a singleton (nâ =â 546â 892 [98.4%]) or twin (nâ =â 8832 [1.6%]) birth who underwent screening for GDM using the 50 g-GCT. METHODS: We compared the screening accuracy, risk of GDM, and risk of LGA between twin and singleton pregnancies using various 50 g-GCT cutoffs. RESULTS: For any given 50 g-GCT result, the probability of GDM was higher (Pâ =â .0.007), whereas the probability of LGA was considerably lower in the twin compared with the singleton group, even when a twin-specific growth chart was used to diagnose LGA in the twin group (Pâ <â .001). The estimated false-positive rate (FPR) for GDM was higher in twin compared with singleton pregnancies irrespective of the 50 g-GCT cutoff used. The cutoff of 8.2 mmol/L (148 mg/dL) in twin pregnancies was associated with an estimated FPR (10.7%-11.1%) that was similar to the FPR associated with the cutoff of 7.8 mmol/L (140 mg/dL) in singleton pregnancies (10.8%). CONCLUSION: The screening performance of the 50 g-GCT for GDM and its correlation with LGA differ between twin and singleton pregnancies.

AIM: To determine the prognostic value of the antepartum 75g-oral glucose tolerance test (OGTT) for future type 2 diabetes mellitus (T2DM) in nulliparous pregnant women who tested negative for GDM. METHODS: A population-based retrospective cohort study of nulliparous pregnant women who underwent testing for GDM using a 75g-OGTT in Ontario, Canada (2007-2017). The overwhelming majority of women in Ontario undergo screening using the preferred 2-step approach where the 75g-OGTT is performed following an abnormal non-fasting 1 h 50g-glucose challenge test. The relationship between the 75g-OGTT results in women who tested negative for GDM (defined as normal glucose at fasting, 1 and 2 h post 75g-glucose load) and future T2DM (as recorded in the Ontario Diabetes Database by the end date of follow up period) was explored. FINDINGS: Of the 162,622 women who underwent 75g-OGTT during the study period, there were 41,507 (75.0%) who met the study criteria. In women without GDM, the adjusted hazard ratios (aHR) for T2DM were-At fasting 2.82 (95%-CI 2.18-3.64), at 1 h 1.26 (1.15-1.37), at 2 h 1.14 (1.04-1.25) for a 1 mmol/L increase in glucose. A model that combined all 3 OGTT values and clinical characteristics could detect 43% (42.6%-43.4%) of those who developed T2DM at 5-years post the index pregnancy for a false-positive rate of 20%. INTERPRETATION: The results of the antepartum OGTT can be used to refine the future risk of T2DM even in nulliparous pregnant women who tested negative for GDM.

OBJECTIVE: Globally, midwife-led units are associated with improved clinical outcomes and childbirth satisfaction, but little is known about the impact of the model on health professionals themselves and interprofessional collaboration. The aim of this research was to describe the experiences of health professionals providing care in Canada's first Alongside Midwifery Unit. DESIGN: A mixed-methods evaluation exploring healthcare provider's experiences using an online survey and qualitative semi-structured interviews and focus groups. SETTING: Canada's first Alongside Midwifery Unit, opened at X in 2018. In the Ontario context, the model reorganizes the way in which midwifery services are integrated in the hospital. PARTICIPANTS: Midwives, obstetricians, nurses, pediatricians, anesthetists, and other healthcare providers participated. MEASUREMENTS & FINDINGS: 82 online surveys, 17 semi-structured interviews and one focus group were completed. Providers agreed that they perceived the Alongside Midwifery Unit was a success (89%) and perceived satisfaction among those receiving care on the unit(93%). The majority of providers were satisfied working on the unit (82%) and reported greater role clarity in the new model (85%) compared to the traditional model of midwifery services. Four main themes emerged from the health professionals' perspectives regarding how the unit impacted care: promoting safety, clarifying roles, facilitating collaboration, and managing change. IMPLICATIONS FOR PRACTICE: Overall, healthcare professionals had positive experiences working on the AMU, including improved role clarity and interprofessional relationships, and they perceived high levels of satisfaction among those giving birth on the unit. Our findings indicate the Alongside Midwifery Unit model can be beneficial for health professionals, women and birthing people.

INTRODUCTION: Rates of perinatal cannabis use are rising, despite clinical evidence about the potential for harm. Accordingly, pregnant and lactating people who perceive a benefit from cannabis use may have a difficult time making informed decisions about cannabis use. METHODS: We conducted a systematic review of mixed-methods research to synthesize existing knowledge on the perspectives of pregnant people and their partners about cannabis use in pregnancy. Six health and social science databases were searched up until May 30, 2021. There were no methodological, time, or geographic limits applied. We employed a convergent integrative approach to the inductive analysis of findings from all studies. RESULTS: We identified 26 studies describing views of 17,781 pregnant and postpartum people about cannabis use in pregnancy. No studies describing the views of partners were identified, and only one study specifically addressed the perspectives of lactating people. Comparative analysis revealed that whether cannabis was studied alone or grouped with other substances resulted in significant diversity in descriptions of participant decision-making priorities and perceptions of risks and benefits. Studies of cannabis alone demonstrated a complex decision-making process whereby perceived benefits are balanced against the available information about risk, which is often unclear and uncertain. Clear and helpful information was difficult to identify, and health care providers were not described as a helpful and trusted resource for decision-making. DISCUSSION: Decision-making about cannabis use is difficult for pregnant and lactating people who perceive a benefit from this use, although this decisional difficulty is seldom reflected in studies that examine cannabis as one of multiple substances that pregnant or lactating people may use. Our review suggests several approaches clinicians may take to encourage open and supportive conversations to facilitate informed decisions about cannabis use during the perinatal period.

INTRODUCTION: Severe maternal morbidity (SMM)-an unexpected pregnancy-associated maternal outcome resulting in severe illness, prolonged hospitalisation or long-term disability-is recognised by many, as the preferred indicator of the quality of maternity care, especially in high-income countries. Obtaining comprehensive details on events and circumstances leading to SMM, obtained through maternity units, could complement data from large epidemiological studies and enable targeted interventions to improve maternal health. The aim of this study is to assess the feasibility of gathering such data from maternity units across Canadian provinces and territories, with the goal of establishing a national obstetric survey system for SMM in Canada. METHODS AND ANALYSIS: We propose a sequential explanatory mixed-methods study. We will first distribute a cross-sectional survey to leads of all maternity units across Canada to gather information on (1) Whether the unit has a system for reviewing SMM and the nature and format of this system, (2) Willingness to share anonymised data on SMM by direct entry using a web-based platform and (3) Respondents' perception on the definition and leading causes of SMM at a local level. This will be followed by semistructured interviews with respondent groups defined a priori, to identify barriers and facilitators for data sharing. We will perform an integrated analysis to determine feasibility outcomes, a narrative description of barriers and facilitators for data-sharing and resource implications for data acquisition on an annual basis, and variations in top-5 causes of SMM. ETHICS AND DISSEMINATION: The study has been approved by the Mount Sinai and Hamilton Integrated Research Ethics Boards. The study findings will be presented at annual scientific meetings of the Society of Obstetricians and Gynaecologists of Canada, North American Society of Obstetric Medicine, and International Network of Obstetric Survey Systems and published in an open-access peer-reviewed Obstetrics and Gynaecology or General Internal Medicine journal.

OBJECTIVE: Excess gestational weight gain (GWG) is associated with adverse long and short-term outcomes for both woman and child, yet evidence demonstrates pregnant women are frequently not engaging in healthy behaviours linked to appropriate weight gain. The purpose of the current study was to explore women's values and beliefs related to weight, nutrition and physical activity during pregnancy and to describe how these beliefs influence their behaviours. METHODS: As part of a larger randomized controlled trial, we conducted 20 focus groups with 66 pregnant women between 16 and 24-weeks gestation using a semi-structured interview guide. Focus groups were recorded and transcribed verbatim and analyzed using a grounded theory approach. RESULTS: Three personal health schemas emerged from the findings which illustrated women's diverging beliefs about their health behaviours in pregnancy. 'Interconnected health' described beliefs regarding the impact their health had on that of their growing baby and awareness of risks associated with inappropriate weight gain. 'Gestational weight gain as an indicator of health' illustrated perceptions regarding how GWG impacted health and the utility of guidelines. Finally, 'Control in pregnancy' described the sense of agency over one's body and health. CONCLUSIONS FOR PRACTICE: Our results showed that health-related behaviours in pregnancy are driven by personal health schemas which are often discordant with clinical evidence. Interventions and health care provider advice aimed at behaviour modification would benefit from first understanding and addressing these schemas. Tackling the conflict between beliefs and behaviour may improve health outcomes associated with appropriate weight gain in pregnancy.

OBJECTIVES: Cerebro-placental ratio (CPR) is a doppler tool contributes to clinical decision-making in pregnancies affected by small for gestational age weight (SGA). Pregnancies affected by gestational diabetes mellitus (GDM) tend to have higher newborn weight, but greater risk of adverse perinatal outcomes. We hypothesized that in GDM-complicated-pregnancies CPR will be associated with adverse perinatal outcomes even in the absence of SGA. METHODS: This prospective single-center cohort study included non-anomalous singleton pregnancies in women with GDM. Those with pre-pregnancy diabetes mellitus, hypertensive disorder or suspected SGA were excluded. Routine fetal sonographic assessment included CPR-defined as middle cerebral artery pulsatilty index/umbilical artery pulsatilty index. Masked CPR measurement closest to birth was used, classified as >10th (normal) or ≤10th centile (low). Primary outcome was a composite, consisting of stillbirth, Caesarean birth due to abnormal fetal heart rate pattern, 5-minute Apgar <7, cord arterial pH < 7.0, hypoxic ischemic encephalopathy, or NICU admission >24 hours. RESULTS: Of 281 participants, 24 (8.5%) had low CPR, at a mean gestational age of 36.3 weeks (IQR 34.0-37.4). Birthweight percentile was significantly lower among the low CPR group (35th [IQR 16-31] versus 60th [IQR 31-82]; P = .002). There was no statistically difference in the primary composite outcome between the groups (8.3% versus 7.0%, P = .68). Low CPR was significantly associated with a higher risk of neonatal hypoglycemia (adjusted odds ratio 3.2, 95% CI 1.2-8.3). CONCLUSION: In pregnancies affected by GDM, CPR ≤10th percentile was not associated with adverse perinatal outcome but was associated with neonatal hypoglycemia.

OBJECTIVE: The growing prevalence of obesity is a concern for midwives. In Canada, the absence of regulatory standards, varying protocols and consultant preferences shape clinical decision making for the midwife and may lead to inconsistent practice. Our aim was to understand the barriers, enablers, and knowledge gaps that influenced experiences of midwives in Ontario, Canada when providing care to clients impacted by obesity. METHODS: Mixed methods design using a sequential, explanatory approach. Surveys conducted with midwives were administered using an online platform, followed by semi-structured interviews to understand the perspectives elicited in the survey in greater detail. Interviews were audio recorded and transcribed verbatim. Survey data were analyzed using descriptive statistics, and thematic analysis was used for generating codes, categories and themes from the interview data. RESULTS: 144 midwives completed the survey and 20 participated in an interview. The participants described their clinical management when caring for those with obesity which included considerations regarding additional tests/investigations, consultation and transfer of care, and place of birth. Up to 93% of surveyed midwives believed that clients with obesity were appropriate for midwifery-led care however there was less certainty about suitability as BMI increased to higher ranges such as > 45). The care management was influenced by beliefs and attitudes, knowledge, and system-level factors. Midwives experienced barriers such as inconsistent practices and role confusion, and felt ill equipped to care for pregnancies affected by obesity due to unclear guidelines. CONCLUSIONS: Overall, midwives believe clients with obesity are suitable for midwifery-led care due to its individualized, non-judgmental approach to care. Additional training for midwives and other obstetric care providers would be beneficial to help overcome barriers in providing effective care to pregnancies affected by obesity.
