A Social-Ecological Model Exploring Gestational Diabetes Mellitus Screening Practices Among Antenatal Health Care Providers.

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.

Impact of Antenatal Care Modifications on Gestational Diabetes Outcomes During the COVID-19 Pandemic.

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.

The femtech revolution-A new approach to pregnancy management: Digital transformation of maternity care-The hybrid e-health perinatal clinic addressing the unmet needs of low- and middle-income countries.

Prenatal care and infant mortality rates are crucial indicators of healthcare quality. However, millions of women in low-income countries lack access to adequate care. Factors such as high-risk pregnancies and unmanaged diet increase the risk of developing complications during pregnancy, highlighting the need for continuous monitoring of maternal health. The increasing burden of non-communicable diseases represents a significant threat to fragile health systems. The lack of access to appropriate prenatal care and poor maternal and newborn health outcomes are major concerns in low- and middle-income countries (LMICs). It emphasizes the need for innovative, integrative approaches to healthcare delivery, especially in pregnant women. The health services need to be reorganized holistically and effectively, focusing on factors that directly impact maternal, neonatal, and infant mortality, resulting in improved access to maternity services and survival of "at-risk" mothers and their offspring in many LMICs. Based on the FIGO (the International Federation of Gynecology & Obstetrics) recommendations of extending preconception care to the postpartum stage, the authors of this review have developed a new model of care-PregCare-based on the triple-intervention-based holistic and multidisciplinary maternal and fetal medicine model for low-risk pregnancies. This model will help transform the traditional model's high visitation frequency into a safe and reduced office visit, while increasing virtual connections, point of care and self-care with doctors, nurses, and community-based providers of self-care. This shall be based on a sophisticated central PregCare call center powered by innovative technologies combined with experienced personnel in perinatal management (doctors and nurses/midwives).

Trends in obstetric anal sphincter injury in spontaneous vaginal delivery versus operative vaginal delivery over a 10-year period: Lessons learned.

OBJECTIVE: To evaluate trends in the incidence of women with obstetric anal sphincter injuries (OASIS) over a 10-year period comparing spontaneous vaginal delivery (SVD) and operative vaginal delivery (OVD). METHODS: A retrospective study was performed in which all women who underwent vaginal delivery over a 10-year period (n = 86 242, 2009-2018) at the Rotunda Hospital were reviewed. The overall incidence of OASIS was compared with incidence rates stratified by parity and type of vaginal birth. RESULTS: The 10-year vaginal delivery rate was 69% (n = 59 187) where 24 580 women (42%) were primiparous and 34 607 women (58%) were multiparous. SVD rate was 74% and OVD rate was 26%. The overall incidence of OASIS was 2.9%. The incidence of OASIS in OVD was 5.5% and the incidence in SVD was 2%. Of 498 multipara who sustained OASIS, 366 (73%) had an SVD without episiotomy compared with 14 (3%) who had an episiotomy. There was a significant reduction of OASIS over the 10-year period in primipara who had an OVD but no reduction in the other groups. CONCLUSION: The primiparous OVD group had a significant reduction of OASIS. Continued education around perineal protection and episiotomy at SVD could positively impact further reduction in OASIS, particularly in the SVD groups.

Maternal age and pregnancy outcomes in twin compared with singleton gestations.

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.

Trends in instrument preference for operative vaginal delivery in a tertiary referral center: 2008-2021.

OBJECTIVE: To examine temporal trends in operative vaginal deliveries as well as the ratio between vacuum and forceps deliveries over 15 years in a large tertiary hospital. METHODS: This retrospective study assessed prospectively collected data from 2008 to 2021. Women with greater than 37 weeks of gestation who underwent an operative vaginal delivery were included. The rate and ratio of instrumental deliveries and perineal trauma were recorded. RESULTS: From 2008 to 2021 there was a total of 109 230 term deliveries, of which 20 151 were an operative vaginal delivery. The rate of operative vaginal delivery as a proportion of all term deliveries decreased from 21.9% (1547 of 7069) in 2008 to 17.1% in 2021 (1428 of 8338, P < 0.001). The ratio between vacuum and forceps-assisted deliveries decreased significantly over the study period, from 7.06 in 2008 to 2.39 in 2021 (P < 0.001). Perineal trauma remained unchanged during the study period. CONCLUSION: Operative vaginal delivery rates declined over the 15-year study period. While vacuum-assisted vaginal deliveries remain the favored instrument, forceps-assisted deliveries are becoming more prevalent. The cause for this change in practice is unclear but is likely multifactorial.

Exploring patients' perspectives of gestational diabetes mellitus screening and counselling in Ontario: A grounded theory study.

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.

Obstetric rectal buttonhole tears: A case series and literature review.

INTRODUCTION: Isolated rectal buttonhole tears are a rare obstetric complication and so there is a lack of consensus for their management. The current case series reviews the published literature on obstetric rectal buttonhole injuries and provides further cases from our institution. METHODS: A literature review was performed and all results were reviewed. Rectal buttonhole tears following vaginal delivery between 2012 and 2022 in our institution were identified. Repair technique and postoperative management were recorded. RESULTS: There were 14 published case reports. Seven case reports described a two-layer closure, and seven reports described a three-layer closure. Four cases were repaired in collaboration with colorectal surgeons. Twelve cases were asymptomatic after 6 weeks. One woman had a defunctioning stoma following a wound breakdown and one woman was readmitted with a rectal hemorrhage. We identified two women in our institution with buttonhole tears. Three-layer repairs were performed in both cases and each woman made an uneventful recovery. CONCLUSION: Repair techniques of rectal buttonhole tears vary among institutions. Despite this variance, most women experience no short-term morbidity following these injuries. This review adds to the current literature with examples of different repair techniques and outcomes.

Dynamic growth changes in fetal growth restriction using serial ultrasonographic biometry and umbilical artery doppler: The multicenter PORTO study.

OBJECTIVE: To describe the growth dynamics of fetuses with initial fetal growth restriction (FGR) later outgrowing the 10th centile for estimated fetal weight with respect to perinatal outcomes and maternal factors. METHODS: A multicenter prospective study recruited 1116 patients for ultrasound surveillance between 2010 and 2012. All pregnancies were growth-restricted singleton gestations between 24 + 0 and 36 + 0 weeks. Biometry and Doppler analysis were carried out, and delivery and adverse perinatal outcomes were recorded. RESULTS: A total of 193 (17%) fetuses outgrew their diagnosis of initial FGR (surpassed the 10th centile) on their last sonogram before delivery. These fetuses were termed "growers," to compare with the true FGR group. The mothers of "growers" were less likely to be smokers (14% vs 25%, P = 0.0001) or affected by hypertensive pregnancy complications (5.2% vs 15%, P = 0.001). Of the growers, 49 (25%) had an abnormal umbilical artery Doppler; however, in most cases (33/49, 67%), this was a single episode of raised umbilical artery pulsatility index, which subsequently normalized. CONCLUSION: There were dynamic growth changes in FGR fetuses, with 17% outgrowing their original diagnosis. Positive growth spurts more commonly occurred in healthy mothers. Once a fetus had outgrown the 10th centile, antenatal surveillance could be decreased.

Placental pathology and neonatal encephalopathy.

Neonatal encephalopathy (NE) is an important cause of neonatal morbidity and mortality worldwide; however, there remain gaps in our knowledge about its pathogenesis. The placenta has been implicated in the pathogenesis of this disease but conclusive evidence related to the placental factors that influence it is sparse. This review aims to outline the current knowledge on the role of the placenta with particular attention to its role in NE as a consequence of hypoxia-ischemia. A total of 26 original articles/review papers were used to compile this review. Three themes were identified from these publications: fetal vascular malperfusion including umbilical cord pathology, inflammatory changes in the placenta, and maternal vascular malperfusion including placental weight. These features were identified as being significant in the development of NE. Advancing our understanding of this relationship between placental pathology and NE may facilitate the development of additional antenatal screening to better identify at-risk fetuses. We highlight areas for further research through antenatal screening and placental histology.

The surgical destabilization of the abductor muscle leads to development of instability-associated hip osteoarthritis in mice.

Osteoarthritis (OA) of the hip is a common and debilitating painful joint disease. However, there is paucity of surgically induced hip OA models in small animals that allow scientists to study the onset and progression of the disease. A growing body of evidence indicates a positive association between periarticular myotendinous pathology and the development of hip OA. Thus, in the current study, we aimed to establish a novel mouse instability-associated hip OA model via selective injury of the abductor complex around the hip joint. C57BL6/J mice were randomized to sham surgery or abductor injury, in which the myotendinous insertion at the third trochanter and greater trochanter were surgically detached. Mice were allowed free active movement until they were sacrificed at either 3 weeks or 20 weeks post-injury. Histologic analyses and immunohistochemical staining of the femoral head articular cartilage were performed, along with microCT (µCT) analysis to assess subchondral bone remodeling. We observed that mice receiving abductor injury exhibited significantly increased instability-associated OA severity with loss of proteoglycan and type II collagen staining compared to sham control mice at 20 weeks post-surgery, while comparable matrix metalloproteinase 13 expression was observed between injury and sham groups. No significant differences in subchondral bone remodeling were found after 3 or 20 weeks following injury. Our study further supports the link between abductor dysfunction and the development of instability-associated hip OA. Importantly, this novel surgically induced hip OA mouse model may provide a valuable tool for future investigations into the pathogenesis and treatment of hip OA.
