Objective: To describe the intrapartum and postpartum use of non-study antibiotics in low- and middle-income countries (LMICs) during the double-blinded NICHD Global Network Azithromycin in Labor (A-PLUS) trial.

Design: The antibiotic use sub-study was a planned prospective, observational sub-study of the A-PLUS trial.

Settings: The study was carried out in hospitals or health centres affiliated with eight sites of the Global Network for Women's and Children's Health Research (Global Network) in seven countries: Bangladesh, Pakistan, India (two sites), Kenya, Zambia, The Democratic Republic of the Congo (DRC) and Guatemala.

Population: Totally, 29 278 pregnant women enrolled in the A-PLUS trial.

Methods: We collected data on 29 278 pregnant women admitted to a facility for delivery related to non-study antibiotic use overall and during three time periods: (1) in the facility prior to delivery, (2) after delivery until facility discharge and (3) after discharge to 42 days post-partum.

Main outcome measures: Non-study antibiotic use overall and for treatment or prophylaxis by the site during the three time periods.

Results: Of the 29 278 women in the study, 5020 (17.1%; 95% CI 16.7%-17.6%) received non-study antibiotics in the facility prior to delivery, 11 956 (40.8%; 95% CI 40.3%-41.4%) received non-study antibiotics in the facility after delivery, and 13 390 (47.6%; 95% CI 47.0%-48.2%) women received non-study antibiotics after delivery and after facility discharge. Antibiotics were prescribed more often among women in the Asian and Guatemalan sites than in the African sites. In the three time-periods, among those receiving antibiotics, prophylaxis was the indication in 82.3%, 97.7% and 90.7% of the cases, respectively. The type of antibiotics used varied substantially by time-period and site, but generally, penicillin-type drugs, cephalosporin-type drugs and metronidazole were used more frequently than other types.

Conclusions: Across the eight sites of the Global Network, in the facility before delivery, and in the post-partum periods before and after facility discharge, antibiotics were used frequently, but use was highly variable by site and time-period.

Objective: To correlate the clinical history with imaging findings of women with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome.

Design: Retrospective cohort study.

Setting: A UK IOTA and ESGO-certified tertiary referral centre for disorders of reproductive development.

Population: All patients with a diagnosis of MRKH and who had undergone an MRI pelvis between 1 January 2011 and 31 April 2021 were included.

Methods: MRI images were analysed by specialist gynaecological radiologists. Clinical data was extracted from an electronic patient record system. Statistical analysis was computed in R (version 4.1.2), R base stats package and ggstatsplot (v0.5.0).

Main outcome measures: Clinical history and predefined imaging features.

Results: One hundred and thirty-four patients were included. Median age at MRI was 18 years (10-64 years). Half (48.2%) of women presenting had a history of pain, most often abdominal (84.6%) or vaginal (9.2%). Remnants were identified in 91.8% of women (n = 123). 4.5% of women had imaging features of endometriosis (n = 6). Women with a functional remnants were significantly more likely to experience pain (p < 0.001). Pain history was not strongly associated with ectopic ovarian position. Common gynaecological pathology such as endometriosis, ovarian cysts and fibroids were also identified.

Conclusions: We identify that majority of women with MRKH will have uterine remnants with a connecting fibrous band, and an ectopic ovarian position 44.0% of cases. Abdominal pain was significantly associated with functional remnants on MRI. Further work is required to identify how other gynaecological pathology impacts women with MRKH.

Objectives: Accurate assessment of gestational age (GA) is important at both individual and population levels. The most accurate way to estimate GA in women who book late in pregnancy is unknown. The aim of this study was to externally validate the accuracy of equations for GA estimation in late pregnancy and to identify the best equation for estimating GA in women who do not receive an ultrasound scan until the second or third trimester.

Design: This was a prospective, observational cross-sectional study.

Setting: 57 prenatal care centres, France.

Participants: Women with a singleton pregnancy and a previous 11-14-week dating scan that gave the observed GA were recruited over an 8-week period. They underwent a standardised ultrasound examination at one time point during the pregnancy (15-43 weeks), measuring 12 foetal biometric parameters that have previously been identified as useful for GA estimation.

Main outcome measures: A total of 189 equations that estimate GA based on foetal biometry were examined and compared with GA estimation based on foetal CRL. Comparisons between the observed GA and the estimated GA were made using R², calibration slope and intercept. RMSE, mean difference and 95% range of error were also calculated.

Results: A total of 2741 pregnant women were examined. After exclusions, 2339 participants were included. In the 20 best performing equations, the intercept ranged from -0.22 to 0.30, the calibration slope from 0.96 to 1.03 and the RSME from 0.67 to 0.87. Overall, multiparameter models outperformed single-parameter models. Both the 95% range of error and mean difference increased with gestation. Commonly used models based on measurement of the head circumference alone were not amongst the best performing models and were associated with higher 95% error and mean difference.

Conclusions: We provide strong evidence that GA-specific equations based on multiparameter models should be used to estimate GA in late pregnancy. However, as all methods of GA assessment in late pregnancy are associated with large prediction intervals, efforts to improve access to early antenatal ultrasound must remain a priority.

Trial registration: The proposal for this study and the corresponding methodological review was registered on PROSPERO international register of systematic reviews (registration number: CRD4201913776).

Objective: Globally, obstetric fistula is a tragic outcome following obstructed labour. Failure of complex repair and post-operative incontinence are common. We describe an innovative surgical technique incorporating the rectus abdominus flap at the time of fistula repair.

Design: Retrospective case series.

Setting: Malawi, Fistula Care Centre.

Methods: Patients were followed for 3 months after discharge to determine continence and healing.

Results: Five of six patients were continent at 3 months and one was lost to follow-up by dry at a one month post-operative phone call. There were no major complications.

Conclusions: The rectus abdominus flap may be a useful adjunct to repair of complex obstetric fistula.
