Two-hundred pregnancies involving 100 women with essential thrombocythemia (ET) were accessed from Mayo Clinic databases (1990-2023). Median platelet count displayed a decline during pregnancy, nadiring at 48% of baseline, in the third trimester: 704-369 × 10/L. Live birth rate was 72%. Of 53 (27%) unintentional pregnancy losses, 48 (24%) occurred in the first trimester. Other fetal complications included preterm birth 3%, intrauterine growth retardation 3%, and stillbirth 1%. Maternal complications included major hemorrhage (7%), preeclampsia (6%), thrombosis (1%), and placental abruption (0.5%). Antepartum management included no specific therapy in 52 (26%), aspirin alone in 112 (56%), aspirin combined with cytoreductive drugs or systemic anticoagulants in 23 (12%), and other permutations in the remaining. Postpartum systemic anticoagulation was documented in 29 (15%) pregnancies. Unintentional first-trimester loss was predicted by prior fetal loss (43% vs. 18%; p < .01), diabetes mellitus (DM; 67% vs. 23%; p = .02), and absence of aspirin therapy (45% vs. 14%; p < .01); the salutary effect of aspirin therapy was independent of the other two risk factors and apparent in both high (presence of ≥1 risk factor; 33% vs. 61%; p = .07) and low (absence of both risk factors; 10% vs. 34%; p < .01) risk scenarios. The benefit of aspirin therapy, in preventing first-trimester loss, was significant in both JAK2-mutated (18% vs. 50%; p < .01) and CALR-mutated (8% vs. 43%; p < .01) cases. Aspirin use was also associated with a lower risk of venous thrombosis (0% vs. 3%; p = .03). By contrast, the use of systemic anticoagulation, antepartum or postpartum, did not influence fetal or maternal complication rates. CALR mutation and DM predicted maternal hemorrhage (13% vs. 4%; p = .05) and preeclampsia (33% vs. 5%; p = .03), respectively. The current study demonstrates the protective role of aspirin in preventing first-trimester loss in ET, independent of driver mutation status or other risk factors.

The Australian & New Zealand Journal of... Jun 2024To examine low birth weight (LBW) in First Nations babies born in a large metropolitan health service in Queensland, Australia.
AIM
To examine low birth weight (LBW) in First Nations babies born in a large metropolitan health service in Queensland, Australia.
MATERIALS AND METHODS
A retrospective population-based study using routinely collected data from administrative data sources. All singleton births in metropolitan health services, Queensland, Australia of ≥20 weeks gestation or at least 400 g birthweight and had information on First Nations status and born between 2019 and 2021 were included. The study measured birthweight and birthweight z-score, and also identified the predictors of LBW. Multivariate regression models were adjusted by demographic, socioeconomic and perinatal factors.
RESULTS
First Nations babies had higher rates of LBW (11.4% vs 6.9%, P < 0.001), with higher rates of preterm birth (13.9% vs 8.8%, P < 0.001). In all babies, the most important factors contributing to LBW were: maternal smoking after 20 weeks of gestation; maternal pre-pregnancy underweight (body mass index <18.5 kg/m); nulliparity; socioeconomic disadvantage; geographical remoteness; less frequent antenatal care; history of cannabis use; pre-existing cardiovascular disease; pre-eclampsia; antepartum haemorrhage; and birth outcomes including prematurity and female baby. After adjusting for all contributing factors, no difference in odds of LBW was observed between First Nations and non-First Nation babies.
CONCLUSIONS
First Nations status was not an independent factor influencing LBW in this cohort, after adjustment for identifiable factors. The disparity in LBW relates to modifiable risk factors, socioeconomic disadvantage, and prematurity. Upscaling culturally safe maternity care, focusing on modifiable risk factors is required to address LBW in Australian women.

Observational Study
BACKGROUND
Obstetric high-dependency care offers holistic care to critically ill obstetric patients while maintaining the potential for early mother-child bonding. Little is known about the obstetric high-dependency unit (HDU) in Ethiopia. Therefore, the objective of the study was to review the admission indications, initial diagnoses, interventions, and patient outcomes in the obstetric high-dependency unit at St.Paul's Hospital.
METHODS
A retrospective observational study was carried out at St. Paul's Hospital in Addis Ababa, Ethiopia, between September 2021 and September 2022, targeting patients in the obstetric high-dependency unit during pregnancy or with in 42 days of termination or delivery. A checklist was used to compile sociodemographic and clinical data. Epidata-4.2 for data entry and SPSS-26 for data analysis were employed. Chi-square tests yielded significant results at p < 0.05.
RESULT
Records of 370 obstetric patients were reviewed and analyzed. The study enlisted participants aged 18 to 40, with a mean age of 27.6 ± 5.9. The obstetric high-dependency unit received 3.5% (95% CI, 3.01-4.30) of all obstetric admissions. With the HDU in place, only 0.42% of obstetric patients necessitated adult intensive care unit (ICU) admission. The predominant motive behind HDU admissions (63.2%) was purely for observation. Hypertensive disorders of pregnancy (48.6%) and obstetric hemorrhage (18.9%) were the two top admission diagnoses. Ten pregnant mothers (2.7%) were admitted to HDU: 2 with antepartum hemorrhages, and 8 with cardiac diseases. Maternal mortality and transfer to the ICU were both 1.4 per 100 HDU patients.
CONCLUSION
Our study found that the most frequent indication for admission to the HDU was just for observational monitoring. Hypertensive disorders of pregnancy and obstetric hemorrhage were the two leading admission diagnoses. Expanding HDUs nationwide is key for mitigating the ICU burden from obstetric admissions. Strategies for early prenatal screening, predicting preeclampsia, and addressing postpartum hemorrhage should be reinforced. Future studies should focus on a broader array of factors affecting fetomaternal outcomes in such a unit.

BACKGROUND
Optimal management of fetuses diagnosed as small for gestational age based on an estimated fetal weight of <10th percentile represents a major clinical problem. The standard approach is to increase fetal surveillance with serial biometry and antepartum testing to assess fetal well-being and timing of delivery. Observational studies have indicated that maternal rest in the left lateral position improves maternal cardiac output and uterine blood flow. However, maternal bed rest has not been recommended based on the results of a randomized clinical trial that showed that maternal rest does not improve fetal growth in small-for-gestational-age fetuses. This study was conducted to revisit this question.
OBJECTIVE
This study aimed to determine whether maternal bed rest was associated with an increase in the fetal biometric parameters that reflect growth after the diagnosis of a small-for-gestational-age fetus.
STUDY DESIGN
A retrospective study was conducted on fetuses who were diagnosed as small for gestational age because of an estimated fetal weight of <10th percentile for gestational age. The mothers were asked to rest in the left lateral recumbent position. Fetal biometry was performed 2 weeks after the diagnosis. All fetuses before entry into the study had a previous ultrasound that demonstrated an estimated fetal weight of >10th percentile. To assess the response to bed rest, the change in fetal biometric parameters (estimated fetal weight, head circumference, abdominal circumference, and femur length) after the recommendation of bed rest was computed for 2 periods: (1) before the diagnosis of a weight of <10th percentile vs at the time of diagnosis of a weight of <10th percentile and (2) at the time of diagnosis of a weight of <10th percentile vs 2 weeks after maternal bed rest. For repeated measures, proportions were compared using the McNemar test, and percentile values were compared using the Kruskal-Wallis test. A P value of <.05 was considered significant. To describe changes in the estimated fetal weight without bed rest, 2 control groups in which the mothers were not placed on bed rest after the diagnosis of a small-for-gestational-age fetus were included.
RESULTS
A total of 265 fetuses were observed before and after maternal bed rest. The following were observed in this study: (1) after 2 weeks of maternal rest, 199 of 265 fetuses (75%) had a fetal weight of >10th percentile; (2) the median fetal weight percentile increased from 6.8 (interquartile range, 4.4-8.4) to 18.0 (interquartile range, 9.5-29.5) after 2 weeks of bed rest; (3) similar trends were noted for the head circumference, abdominal circumference, and femur length. In the groups of patients who were not asked to be on bed rest, a reassignment to a weight of >10th percentile at a follow-up examination only occurred in 7 of 37 patients (19%) in the Texas-Michigan group and 13 of 111 patients (12%) in the Colorado group compared with the bed rest group (199/265 [75%]) (P<.001).
CONCLUSION
Patients who were prescribed 2 weeks of bed rest after the diagnosis of a fetal weight of <10th percentile had an increase in weight of >10th percentile in 199 of 265 fetuses (75%). This increase in fetal weight was significantly higher than that in the 2 control groups in which bed rest was not prescribed. This observation suggests that bed rest improves fetal growth in a subset of patients.

Fertility and Sterility Jun 2024To determine whether obstetric outcomes differ between women with endometriosis and those without, where all women undergo first-trimester screening for endometriosis.
OBJECTIVE
To determine whether obstetric outcomes differ between women with endometriosis and those without, where all women undergo first-trimester screening for endometriosis.
DESIGN
A prospective observational cohort study.
SETTING
The Early Pregnancy Unit at University College London Hospital, United Kingdom.
PATIENTS
Women with a live pregnancy progressing beyond 12 weeks' gestation and concurrent endometriosis (n = 110) or no endometriosis (n = 393).
INTERVENTION
All women underwent a pelvic ultrasound examination in early pregnancy to examine for the presence of endometriosis and uterine abnormalities.
MAIN OUTCOME MEASURES
The primary outcome of interest was preterm birth, defined as delivery before 37 completed weeks' gestation. Secondary outcomes included late miscarriage, antepartum hemorrhage, placental site disorders, gestational diabetes, hypertensive disorders of pregnancy, neonates small for gestational age, mode of delivery, intrapartum sepsis, postpartum hemorrhage, and admission to the neonatal unit.
RESULTS
Women with a diagnosis of endometriosis did not have statistically significantly higher odds of preterm delivery (adjusted odds ratio [aOR] 1.85 [95% confidence interval {CI} 0.50-6.90]), but they did have higher odds of postpartum hemorrhage during cesarean section (aOR 3.64 [95% CI 2.07-6.35]) and admission of their newborn infant to the neonatal unit (aOR 3.24 [95% CI 1.08-9.73]). Women with persistent or recurrent deep endometriosis after surgery also had higher odds of placental site disorders (aOR 8.65 [95% CI 1.17-63.71]) and intrapartum sepsis (aOR 3.47 [95% CI 1.02-11.75]).
CONCLUSION
We observed that women with endometriosis do not have higher odds of preterm delivery, irrespective of their disease subtype. However, they do have higher odds of postpartum hemorrhage during the cesarean section and newborn admission to the neonatal unit.

Pre-eclampsia (PE) is a hypertensive disorder characterised by systemic vascular resistance and endothelial dysfunction. It is known to influence choroidal thickness (CT). No previous studies have explored the antepartum and postpartum changes in CT with respect to the protein-creatinine ratio (PCR), a measure of proteinuria that is a clinical hallmark of PE. This study evaluated the correlations between antepartum and postpartum CT and the PCR in patients with PE. In this retrospective study, sixty-six eyes (66 patients) were analysed. The patients were divided into two groups according to the median PCR value (2.36 mg/mg): low PCR group (< 2.36 mg/mg) and high PCR group (≥ 2.36 mg/mg). Ophthalmologic clinical data were collected and assessed. We observed higher antepartum CT and higher mean arterial pressure in high PCR group than in low PCR group. Moreover, postpartum CT decreased significantly in high PCR group. In the multivariate analysis, CT changes were correlated with antepartum CT and antepartum PCR after logarithm transformation. In conclusion, a greater decrease in CT was observed in high PCR group than in low PCR group. Further, the antepartum PCR showed a correlation with the extent of CT reduction.

Randomized Controlled Trial
Lactation relies on the secretion of two key hormones, prolactin and oxytocin. Studies have shown that yoga in the postpartum period can stimulate feelings of comfort and relaxation, which increases oxytocin production. The aim of this study was to evaluate the effect of yoga training on postpartum prolactin and oxytocin levels in a group of primipara women. This quasi-experimental study included 60 healthy primigravida, primipara women in their third trimester who attended antepartum and postpartum care at four primary healthcare centers in Kediri Regency. The participants were randomly allocated to an intervention group ( = 30) and a control ( = 30) group. The intervention group received health education and participated at eight yoga sessions with a duration of 60 min, from week 32 of gestation until the postpartum period. The control group received standard antepartum and postpartum care. Prolactin and oxytocin levels were measured in weeks 1 and 6 postpartum. Mean prolactin increment was significantly higher in the intervention group (176.8 ± 66.6 ng/ml) than the control group (24.8 ± 39.5 ng/ml). Similarly, mean oxytocin increment was significantly higher in the intervention group (58.6 ± 31.59 pg/ml) than the control group (14.6 ± 36.06 pg/ml). Our results suggest that yoga training in the third trimester until the postpartum period increases prolactin and oxytocin levels among primipara postpartum women.

Observational Study
OBJECTIVE
Endometriosis is associated with higher risk of ectopic pregnancy, premature delivery, miscarriage, and other adverse maternal and fetal complications. This study aimed to assess the impact of endometriosis on maternal and fetal outcomes of singleton pregnancies in a large nationally representative database.
MATERIALS AND METHODS
This population-based, retrospective observational study extracted the data of women aged 20-49 years with singleton, spontaneously conceived pregnancies from the US Nationwide Inpatient Sample (NIS) database from 2005 to 2018. Included subjects were divided into those with ICD codes for endometriosis and those without (non-endometriosis group). Data of maternal and fetal outcomes were compared between groups and analyzed using regression analysis.
RESULTS
After excluding 17,124 women who conceived with assisted reproductive technology (ART), 162,155 women with multiple pregnancies, and 27,847 with abnormal trend weight values (TRENDWT), a total of 8,584,269 women were eligible. After propensity score matching (PMS) case-control 1:4 by age, 45,560 remained (9112 (0.1%) with endometriosis, 36,448 without) and were included in the analysis. The mean age of women before matching was 28.7 years, and 30.5 years after matching. The most common comorbidity was chronic pulmonary disease (3.6%). Smoking frequency was higher in women with endometriosis compared to those without (4.8% vs. 2.4%). Multivariable analysis adjusted for confounders revealed that endometriosis was associated with significantly higher risk of maternal complications, including pre-eclampsia and eclampsia, antepartum hemorrhage, placenta previa, Cesarean delivery, post-partum hemorrhage, disseminated intravascular coagulation (DIC), transfusion, hemoperitoneum, and hospital stays ≥6 days. For fetal outcomes, endometriosis was associated with higher risk of intrauterine growth restriction (IUGR), premature birth, birth defects and abortion.
CONCLUSION
Endometriosis during pregnancy is associated with maternal and fetal complications. Study findings may serve as a benchmark for expanding medical assistance for endometriosis-affected pregnant women.

The vaginal tract comprises commensal microorganisms, which play an essential role in the health of the reproductive tract. Any dysbiosis in the vaginal microenvironment may lead to severe urinary tract infections or even infertility. This study aimed to evaluate the aerobic bacterial flora isolated from vaginal samples from 100 lactating bitches in the antepartum period ( = 3), postpartum period ( = 80), and with ( = 17). Before vaginal swabs, all the bitches went through a gynecology consult, along with milk and blood sampling. Standard microbiological techniques were used for bacterial isolation. Among the 100 vaginal samples analyzed, 82% had a positive microbiological outcome, while 18% were negative. The microbiologic profile listed 17 different genera. The main isolated bacterial families were Micrococcaceae, Staphylococcaceae, Morganellaceae, Bacillaceae, and Rhizobiaceae. At the same time, strains like , , , , , or were isolated for the first time from the vaginal secretion of lactating bitches. The microbiological data demonstrates that lactating bitches' vaginal discharge is heterogeneous and may be affected by coitus, sampling season, age, and reproductive status.
