    OBJECTIVE: To evaluate the superficial surgical site infection (SSI) rate to 28 days and patient satisfaction with wound coverage management when their transverse suprapubic caesarean wound is left exposed compared with dressed after skin closure.

    DESIGN: Randomised trial.

    SETTING: University Hospital, Malaysia: April 2016-October 2016.

    POPULATION: 331 women delivered by caesarean section.

    METHOD: Participants were randomised to leaving their wound entirely exposed (n = 165) or dressed (n = 166) with a low adhesive dressing (next day removal).

    MAIN OUTCOME MEASURES: Primary outcomes were superficial SSI rate (assessed by provider inspection up to hospital discharge and telephone questionnaires on days 14 and 28) and patient satisfaction with wound coverage management before hospital discharge.

    RESULTS: The superficial SSI rates were 2/153 (1.3%) versus 5/157 (3.2%) (relative risk [RR] 0.4, 95% CI 0.1-2.1; P = 0.45) and patient satisfaction with wound management was 7 [5-8] versus 7 [5-8] (P = 0.81) in exposed compared with dressed study groups, respectively. In the wound-exposed patients, stated preference for wound exposure significantly increased from 35.5 to 57.5%, whereas in the wound-dressed patients, the stated preference for a dressed wound fell from 48.5 to 34.4% when assessed at recruitment (pre-randomisation) to day 28. There were no significant differences in inpatient additional dressing or gauze use for wound care, post-hospital discharge self-reported wound issues of infection, antibiotics, redness and inflammation, swollen, painful, and fluid leakage to day 28 across trial groups.

    CONCLUSION: The trial is underpowered as SSI rates were lower than expected. Nevertheless, leaving caesarean wounds exposed does not appear to have detrimental effects, provided patient counselling to manage expectations is undertaken.

    TWEETABLE ABSTRACT: An exposed compared with a dressed caesarean wound has a similar superficial surgical site infection rate, patient satisfaction and appearance.

    OBJECTIVE: To evaluate fasting for 12 hours compared with expedited oral feeding in hospitalised women with hyperemesis gravidarum (HG).

    DESIGN: Randomised trial.

    SETTING: University Hospital, Malaysia: April 2016-April 2017.

    POPULATION: One hundred and sixty women hospitalised for HG.

    METHOD: Women were randomised upon admission to fasting for 12 hours or expedited oral feeding. Standard HG care was instituted.

    MAIN OUTCOME MEASURE: Primary outcome was satisfaction score with overall treatment at 24 hours (0-10 Visual Numerical Rating Scale VNRS), vomiting episodes within 24 hours and nausea VNRS score at enrolment, and at 8, 16 and 24 hours.

    RESULTS: Satisfaction score, median (interquartile range) 8 (5-9) versus 8 (7-9) (P = 0.08) and 24-hour vomiting episodes were 1 (0-4) versus 1 (0-5) (P = 0.24) for 12-hour fasting versus expedited feeding, respectively. Repeated measures analysis of variance of nausea scores over 24 hours showed no difference (P = 0.11) between trial arms. Participants randomised to 12-hour fasting compared with expedited feeding were less likely to prefer their feeding regimen in future hospitalisation (41% versus 65%, P = 0.001), to recommend to a friend (65% versus 84%, P = 0.01; RR 0.8, 95% CI 0.6-0.9) and to adhere to protocol (85% versus 95%, P = 0.04; RR 0.9, 95% CI 0.8-1.0). Symptoms profile, ketonuria status at 24 hours and length of hospital stay were not different.

    CONCLUSION: Advisory of 12-hour fasting compared with immediate oral feeding resulted in a non-significant difference in satisfaction score but adherence to protocol and fidelity to and recommendation of immediate oral feeding to a friend were lower. The 24-hour nausea scores and vomiting episodes were similar.

    TWEETABLE ABSTRACT: Women hospitalised for hyperemesis gravidarum could feed as soon, as much and as often as can be tolerated compared with initial fasting.

    OBJECTIVE: Vaginal childbirth has a substantial effect on pelvic organ supports, which may be mediated by levator ani (LA) avulsion or hiatal overdistension. Although the impact of a first vaginal delivery on the hiatus has been investigated, little is known about the effect of subsequent births. This study was designed to evaluate the association between vaginal parity and hiatal dimension.

    DESIGN: Retrospective observational study.

    SETTING: A tertiary urogynaecological unit in Australia.

    POPULATION: A total of 780 archived data sets of women seen for symptoms of lower urinary tract and pelvic floor dysfunction.

    METHODS: Standardised in-house interview and assessment using the International Continence Society (ICS) pelvic organ prolapse quantification (POP-Q), and four-dimensional translabial ultrasound. Offline analysis for hiatal dimensions was undertaken blinded to history and clinical examination.

    MAIN OUTCOME MEASURES: Hiatal area on maximum Valsalva.

    RESULTS: Of 780 women, 64 were excluded because of missing ultrasound volumes, leaving 716 for analysis: 96% (n = 686) were parous, with a median parity of three (interquartile range, IQR 2-3), and 91.2% (n = 653) were vaginally parous. Levator avulsion was found in 21% (n = 148). The mean hiatal area on Valsalva was 29 cm(2) (SD 9.4 cm(2) ). On one-way anova, vaginal parity was significantly associated with hiatal area (P < 0.001). Most of the effect seems to occur with the first delivery. Subsequent deliveries do not seem to have any significant effect on hiatal dimensions. This remained true after controlling for potential confounding factors using multivariate regression analysis (P = 0.0123).

    CONCLUSIONS: Vaginal parity was strongly associated with hiatal area on Valsalva. Most of this effect seems to be associated with the first vaginal delivery.

    OBJECTIVE: To examine the contribution of preterm birth and size-for-gestational age in stillbirths using six 'newborn types'.

    DESIGN: Population-based multi-country analyses.

    SETTING: Births collected through routine data systems in 13 countries.

    SAMPLE: 125 419 255 total births from 22+0 to 44+6 weeks' gestation identified from 2000 to 2020.

    METHODS: We included 635 107 stillbirths from 22+0  weeks' gestation from 13 countries. We classified all births, including stillbirths, into six 'newborn types' based on gestational age information (preterm, PT, <37+0  weeks versus term, T, ≥37+0  weeks) and size-for-gestational age defined as small (SGA, <10th centile), appropriate (AGA, 10th-90th centiles) or large (LGA, >90th centile) for gestational age, according to the international newborn size for gestational age and sex INTERGROWTH-21st standards.

    MAIN OUTCOME MEASURES: Distribution of stillbirths, stillbirth rates and rate ratios according to six newborn types.

    RESULTS: 635 107 (0.5%) of the 125 419 255 total births resulted in stillbirth after 22+0  weeks. Most stillbirths (74.3%) were preterm. Around 21.2% were SGA types (PT + SGA [16.2%], PT + AGA [48.3%], T + SGA [5.0%]) and 14.1% were LGA types (PT + LGA [9.9%], T + LGA [4.2%]). The median rate ratio (RR) for stillbirth was highest in PT + SGA babies (RR 81.1, interquartile range [IQR], 68.8-118.8) followed by PT + AGA (RR 25.0, IQR, 20.0-34.3), PT + LGA (RR 25.9, IQR, 13.8-28.7) and T + SGA (RR 5.6, IQR, 5.1-6.0) compared with T + AGA. Stillbirth rate ratios were similar for T + LGA versus T + AGA (RR 0.7, IQR, 0.7-1.1). At the population level, 25% of stillbirths were attributable to small-for-gestational-age.

    CONCLUSIONS: In these high-quality data from high/middle income countries, almost three-quarters of stillbirths were born preterm and a fifth small-for-gestational age, with the highest stillbirth rates associated with the coexistence of preterm and SGA. Further analyses are needed to better understand patterns of gestation-specific risk in these populations, as well as patterns in lower-income contexts, especially those with higher rates of intrapartum stillbirth and SGA.

    OBJECTIVE: To assess the utility of placental growth factor (PlGF) levels and the soluble fms-like tyrosine kinase-1/placental growth factor (sFlt-1/PlGF) ratio to predict preterm birth (PTB) for infants with fetal growth restriction (FGR) and those appropriate for gestational age (AGA).

    DESIGN: Prospective, observational cohort study.

    SETTING: Tertiary maternity hospital in Australia.

    POPULATION: There were 320 singleton pregnancies: 141 (44.1%) AGA, 83 (25.9%) early FGR (<32+0  weeks) and 109 (30.0%) late FGR (≥32+0  weeks).

    METHODS: Maternal serum PlGF and sFlt-1/PlGF ratio were measured at 4-weekly intervals from recruitment to delivery. Low maternal PlGF levels and elevated sFlt-1/PlGF ratio were defined as <100 ng/L and >5.78 if <28 weeks and >38 if ≥28 weeks respectively. Cox proportional hazards models were used. The analysis period was defined as the time from the first measurement of PlGF and sFlt-1/PlGF ratio to the time of birth or censoring.

    MAIN OUTCOME MEASURES: The primary study outcome was overall PTB. The relative risks (RR) of birth within 1, 2 and 3 weeks and for medically indicated and spontaneous PTB were also ascertained.

    RESULTS: The early FGR cohort had lower median PlGF levels (54 versus 229 ng/L, p

    AIM: To develop evidence-based clinical algorithms for management of common intrapartum urinary abnormalities.

    POPULATION: Women with singleton, term pregnancies in active labour and immediate postnatal period, at low risk of complications.

    SETTING: Healthcare facilities in low- and middle-income countries.

    SEARCH STRATEGY: A systematic search and review were conducted on the current guidelines from WHO, NICE, ACOG and RCOG. Additional search was done on PubMed and The Cochrane Database of Systematic Reviews up to May 2020.

    CASE SCENARIOS: Four common intrapartum urinary abnormalities were selected: proteinuria, ketonuria, glycosuria and oliguria. Using reagent strip testing, glycosuria was defined as ≥2+ on one occasion or of ≥1+ on two or more occasions. Proteinuria was defined as ≥2+ and presence of ketone indicated ketonuria. Oliguria was defined as hourly urine output ≤30 ml. Thorough initial assessment using history, physical examination and basic investigations helped differentiate most of the underlying causes, which include diabetes mellitus, dehydration, sepsis, pre-eclampsia, shock, anaemia, obstructed labour, underlying cardiac or renal problems. A clinical algorithm was developed for each urinary abnormality to facilitate intrapartum management and referral of complicated cases for specialised care.

    CONCLUSIONS: Four simple, user-friendly and evidence-based clinical algorithms were developed to enhance intrapartum care of commonly encountered maternal urine abnormalities. These algorithms may be used to support healthcare professionals in clinical decision-making when handling normal and potentially complicated labour, especially in low resource countries.

    TWEETABLE ABSTRACT: Evidence-based clinical algorithms developed to guide intrapartum management of commonly encountered urinary abnormalities.
