Neonatal Birth Weight With Daily Compared With Every-Other-Day Glucose Monitoring in Gestational Diabetes Mellitus: A Randomized Controlled Trial.

OBJECTIVE: To assess whether universal use of every-other-day glucose monitoring in patients with gestational diabetes mellitus (GDM) resulted in similar birth weights and medication use and was preferred by the patient compared with traditional daily glucose monitoring. METHODS: This was a noninferiority randomized controlled trial conducted at a single New York City hospital between April 2021 and May 2022. Patients with singleton pregnancies who were diagnosed with GDM after 20 weeks of gestation and had a minimum of 7 days of previous daily blood glucose testing were randomly assigned to test blood glucose values daily or every other day. The primary outcome was neonatal birth weight. We calculated a total sample size of 196 participants needed for noninferiority to be tested, assuming the mean birth weight in the every-other-day group, compared with the daily group, was no higher than the predefined noninferiority margin of 200 g (80% power and one-sided alpha of 0.05). Postrandomization characteristics, including blood glucose values and medication initiation and timing, were recorded. Satisfaction with treatment group was assessed using the validated Oxford Maternity Diabetes Treatment Satisfaction Questionnaire. RESULTS: A total of 197 patients were randomized: 98 in the daily group and 99 in the every-other-day group. Baseline characteristics were similar between groups. The mean neonatal birth weight was similar between groups (mean±SD 3,090±418 g among newborns in the daily group compared with 3,181±482 g among newborns in the every-other-day group). For the primary outcome, the every-other-day group was found to be noninferior to the daily group with an upper confidence limit for the mean difference in mean birth weight of 197 g, which was below the noninferiority margin of 200 g (P=.046). Postrandomization, there were no significant differences in the number of patients who required medication, the gestational age at which medication was started, or the type of medication used. Average fasting and postprandial glucose values were similar between groups. There was an increase in adherence to treatment group in those randomized to every-other-day blood sugars, but no difference in patient satisfaction. CONCLUSION: In patients with GDM, testing blood glucose values every other day was as effective as testing daily, without apparent effects on birth weight, medication initiation, or glucose control. Reduced frequency of blood glucose monitoring might help decrease the emotional, physical, and financial burden experienced by patients with GDM.

Transient elastography and controlled attenuation parameter to evaluate hepatic steatosis and liver stiffness in postpartum patients.

INTRODUCTION: Nonalcoholic fatty liver disease (NAFLD) affects 30% of adults in the United States. Transient elastography (TE) (Fibroscan, Echosens, Paris, France) with controlled attenuation parameter (CAP) is a noninvasive way to evaluate liver steatosis and liver stiffness. The primary objective of this study was to assess prevalence of elevated liver stiffness and steatosis immediately postpartum. Furthermore, we sought to evaluate whether there were differences in rates of metabolic disorders of pregnancy (gestational diabetes mellitus (GDM), gestational hypertension, and preeclampsia) and pre-pregnancy conditions (type 2 diabetes mellitus (DM), chronic hypertension, and obesity) in those with elevated postpartum liver steatosis/liver stiffness. METHODS: IRB approved prospective cross-sectional study in which TE and liver function tests were performed 1-2 days postpartum. CAP ≥300 dB/m was classified as significant steatosis. Increased liver stiffness was defined as ≥7 kPa. Prevalence was determined by proportion of individuals undergoing TE/CAP who met criteria. Chi-square analysis was used to compare differences between groups. RESULTS: Eighty-nine patients were included: 20 (22%) had GDM, 13 (15%) had gestational hypertension, and 15 (17%) had preeclampsia. Women with kPa ≥7 were more likely to have ALT ≥25, type 2 diabetes, and preeclampsia (p < .05). Pre-gravid BMI, BMI at delivery, and GDM were not associated with increased kPa. Pregravid BMI ≥25 and chronic hypertension were associated with CAP ≥ 300 dB/m (p < .05). GDM, preeclampsia, and gestational hypertension were not associated with CAP ≥300 dB/m. CONCLUSIONS: Patients with preeclampsia, type 2 diabetes, and elevated ALT were more likely to have elevated postpartum liver stiffness. Pregravid BMI ≥25 and ≥30 were associated with increased liver steatosis, although did not impact liver stiffness. GDM was not associated with increased liver stiffness or steatosis. Consideration should be made for screening pregnant patients with preeclampsia, type 2 DM and overweight or obese BMI for liver disease in the postpartum period with potential for lifestyle intervention.

Incidentally Found Midtrimester Shortened Cervical Length: Practice Patterns among American Maternal-Fetal Medicine Specialists.

OBJECTIVE: The management of incidentally found short cervical length (CL) without prior spontaneous preterm birth (PTB) can vary. While most agree on starting vaginal progesterone, management after CL shortens <10 mm varies. The purpose of this study was to elucidate current practice patterns amongst maternal-fetal medicine (MFM) specialists. STUDY DESIGN: We conducted an online survey of MFM attending physicians and fellows in the United States from May 2019 to April 2020. The primary outcome was management of varying CL based on gestational age. Variations in management were assessed descriptively. RESULTS: There were 236 respondents out of 400 eligible surveyed, with a response rate of 59.2%. Universal CL screening was reported by 93.6% (49.6% abdominal and 44.1% transvaginal). Management of short CL varied based on CL measurement, rather than gestational age at presentation. At CL <10 mm, management included cerclage (17.4-18.7%), vaginal progesterone (41.3-41.7%), or cerclage plus vaginal progesterone (43.4%). Between CL of 10 to 20 mm, the majority (77.4-91.9%) would start vaginal progesterone. At CL 21 to 25 mm, management varied between expectant management (45.5-48.5%) or vaginal progesterone (51.1-52.8%). Suture material used was ethylene terephthalate (47.4%) or polypropelene (31.2). Preoperative antibiotic use was reported by 22.3%, while 45.5% used them only if the amniotic membranes were exposed, and 32.2% reported no antibiotic use. Postoperative tocolytic use varied with 19.3% reporting no use, 32.6% using it always, 8.2% only after significant cervical manipulation, 22.7% after the patient is experiencing symptoms, and 17.6% using it only if the cervix is dilated on exam. After cerclage placement, 44.5% continued CL surveillance. CONCLUSION: Substantial differences of opinion exist among MFM physicians regarding management of incidentally found short CL in patients without history of PTB. The differences in responses obtained highlight the need for evidence-based guidelines for managing this clinical scenario. KEY POINTS: · There is lack of consensus on the management of incidentally found shortened CL.. · The purpose of this study was to elucidate current trends in CL screening and management.. · Substantial differences of opinion exist regarding management of incidentally found short CL..
