    OBJECTIVE: To evaluate immediate compared with on-demand full maternal oral feeding after caesarean delivery STUDY DESIGN: A randomised trial.

    SETTING: Obstetric unit of a university hospital in Kuala Lumpur, Malaysia.

    POPULATION: Women admitted for a planned caesarean under spinal anaesthesia.

    METHODS: Participants were randomised to a sandwich meal served immediately on return to the ward or on-demand.

    MAIN OUTCOME MEASURES: Primary outcomes were patient satisfaction VAS (visual analog scale of 100 mm) on the feeding regimen and vomiting at 24 hours.

    RESULTS: 453 women were initially enrolled, 395 were randomised and available for analysis. Median (full range) patient satisfaction VAS scores were 82 (15-100) versus 84 (0-100) mm, P = 0.88 and vomiting rates were 1/197 (0.5%) versus 2/198 (1.0%), P > 0.99 for immediate compared with on-demand feeding, respectively. The immediate versus on-demand arms first ate at a median of 105 (35-210) versus 165 (45-385) minutes, P

    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.

    PURPOSE: To compare 3 consecutive days of hyperglycemic response following antenatal dexamethasone regimens of 12-mg or 6-mg doses 12 hourly in diet-controlled gestational diabetes.

    METHODS: A randomized controlled trial was carried out in a university hospital in Malaysia. Women with lifestyle-controlled gestational diabetes scheduled to receive clinically indicated antenatal corticosteroids (dexamethasone) were randomized to 12-mg 12 hourly for one day (2 × 12-mg) or 6-mg 12-hourly for two days (4 × 6-mg). 6-point (pre and 2-h postprandial) daily self-monitoring of capillary blood sugar profile for up to 3 consecutive days was started after the first dexamethasone injection. Hyperglycemia is defined as blood glucose pre-meal ≥ 5.3 or 2 h postprandial ≥ 6.7 mmol/L. The primary outcome was a number of hyperglycemic episodes in Day-1 (first 6 BSP points). A sample size of 30 per group (N = 60) was planned.

    RESULTS: Median [interquartile range] hyperglycemic episodes 4 [2.5-5] vs. 4 [3-5] p = 0.3 in the first day, 3 [2-4] vs. 1 [0-3] p = 0.01 on the second day, 0 [0-1] vs. 0 [0-1] p = 0.6 on the third day and over the entire 3 trial days 7 [6-9] vs. 6 [4-8] p = 0.17 for 6-mg vs. 12-mg arms, respectively. 2/30 (7%) in each arm received an anti-glycemic agent during the 3-day trial period (capillary glucose exceeded 11 mmol/L). Mean birth weight (2.89 vs. 2.49 kg p

    OBJECTIVE: To evaluate the combined effect of massage and warm compress to the perineum (MassComp) compared with standard "hands-off" in the second stage of labor.

    METHODS: A randomized trial was conducted in a University hospital in Malaysia. Nulliparous women at term who were about to start pushing were randomized to massage during pushing and warm compress to the perineum in between pushes or to standard "hands-off" care. Primary outcome was suturing for perineal injury (episiotomy or tear).

    RESULTS: A total of 156 participants were analyzed based on intention to treat. Perineal repair rates were 53/79 (67%) for MassComp versus 70/77 (91%) for control (relative risk [RR] 0.72, 95% confidence interval [CI] 0.61-0.98, number needed to treat for an additional beneficial outcome [NNTb ] 5, 95% CI 2.83-8.62, P

    OBJECTIVE: To evaluate immediate oxytocin and early amniotomy compared with delayed amniotomy after Foley catheter cervical ripening in nulliparous women on intervention-to-delivery interval.

    METHODS: A randomized trial was conducted from September 2020 to March 2021. A total of 140 term nulliparas (70 early amniotomy, 70 delayed amniotomy) with Foley catheter-ripened cervices (dilatation ≥3 cm achieved), singleton fetus, cephalic presentation with intact membranes, and reassuring fetal heart rate tracing were recruited. Women were randomized to immediate titrated intravenous oxytocin infusion and early amniotomy or delayed amniotomy (after 4 h of oxytocin). The primary outcome was intervention (oxytocin)-to-delivery interval (h).

    RESULTS: Intervention-to-delivery intervals (h) were mean ± standard deviation 9.0 ± 3.6 versus 10.6 ± 3.5 h (mean difference of 1.4 h) (P = 0.004) for the early versus delayed amniotomy arms, respectively. Birth rates at 6 h after oxytocin infusion were 19 of 70 (27.1%) versus 8 of 70 (11.4%) (relative risk, 2.38 [95% confidence interval (CI), 1.11-5.06]; number needed to treat: 7 [95% CI, 3.5-34.4]) (P = 0.03), cesarean delivery rates were 29 of 70 (41.4%) versus 33 of 70 (47.1%) (relative risk, 0.88; 95% CI, 0.61-1.28) (P = 0.50), and maternal satisfaction on birth process were a median of 7 (interquartile range, 7-8) versus 7 (interquartile range, 7-8) (P = 0.40) for the early versus delayed amniotomy arms, respectively.

    CONCLUSION: In term nulliparas with cervices ripened by Foley catheter, immediate oxytocin and early amniotomy compared with a planned 4-h delay to amniotomy shortened the intervention-to-delivery interval but did not significantly reduce the cesarean delivery rate.

    INTRODUCTION: Multiparous labor inductions are typically successful, and the process can be rapid, starting from a ripened cervix with a predictable response to amniotomy and oxytocin infusion. Outpatient Foley catheter labor induction in multiparas with unripe cervixes is a feasible option as the mechanical process of ripening is usually without significant uterine contractions and well tolerated. Labor contractions can be initiated by amniotomy and titrated oxytocin infusion in the hospital for well-timed births during working hours as night birth are associated with adverse events. We sought to evaluate outpatient compared with inpatient Foley catheter induction of labor in multiparas for births during working hours and maternal satisfaction.

    MATERIAL AND METHODS: A randomized trial was conducted in the University of Malaya Medical Center. A total of 163 term multiparas (no dropouts) with unripe cervixes (Bishop score ≤5) scheduled for labor induction were randomized to outpatient or inpatient Foley catheter. Primary outcomes were delivery during "working hours" 08:00-18:00 h and maternal satisfaction on allocated care (assessed by 11-point visual numerical rating score 0-10, with higher score indicating more satisfied).

    CLINICAL TRIAL REGISTRATION: ISRCTN13534944.

    RESULTS: Comparing outpatient and inpatient arms, delivery during working hours were 54/82 (65.9%) vs. 48/81 (59.3%) (relative risk 1.1, 95% CI 0.9-1.4, p = 0.421) and median maternal satisfaction visual numerical rating score was 9 (interquartile range 9-9) vs. 9 (interquartile range 8-9, p = 0.134), repectively. Duration of hospital stay and membrane rupture to delivery interval were significantly shorter in the outpatient arm: 35.8 ± 20.2 vs. 45.2 ± 16.2 h (p = 0.001) and 4.1 ± 2.9 vs. 5.3 ± 3.6 h (p = 0.020), respectively. Other maternal and neonatal secondary outcomes were not significantly different.

    CONCLUSIONS: The trial failed to demonstrate the anticipated increase in births during working hours with outpatient compared with inpatient induction of labor with Foley catheter in parous women with an unripe cervix. Hospital stay and membrane rupture to delivery interval were significantly shortened in the outpatient group. The rate of maternal satisfaction was high in both groups and no significant differences were found.

    PURPOSE: To evaluate Foley catheter and controlled release dinoprostone insert compared to foley catheter alone on induction to delivery interval and maternal satisfaction.

    METHODS: A randomized trial was conducted in a university hospital in Malaysia from December 2018 to May 2019. Term nulliparas with unfavorable cervix (Bishop score ≤ 5) scheduled for labor induction were randomized to Foley catheter and controlled release dinoprostone insert simultaneously or Foley catheter alone. Primary outcomes were induction to delivery interval (hours) and maternal satisfaction on birth experience (assessed by 11-point Visual Numerical Rating Scale VNRS 0-10, higher score more satisfied).

    RESULTS: Induction to vaginal delivery intervals was mean ± standard deviation 22.5 ± 10.4 vs. 35.1 ± 14.9 h, P =

    AIM: To explore digital insertion in dorsal recumbent position of 16F, 22F, or 28F catheter bores on insertion failure, duration, and pain in unripe cervix labor induction.

    METHODS: A randomized trial was performed in a University hospital in Malaysia. Term women scheduled for labor induction, Bishop score ≤ 5, singleton, cephalic presentation, intact membrane, and reassuring pre-induction fetal heart rate tracing were recruited. Women with known gross fetal anomaly, allergy to latex and inability to consent or language difficulty were excluded. Participants were randomized to 16F, 22F, or 28F Foley catheter. Primary outcome was insertion failure and main secondary outcomes were insertion duration and pain (assessed by a Visual Numerical Rating Scale [VNRS] 0-10, higher score more pain). Analysis is done by analysis of variance (ANOVA), Kruskal-Wallis, and chi square test across the three arms and by t test and Mann-Whitney U test for pair wise comparisons.

    RESULTS: One hundred twenty-seven participants' data were analyzed. The insertion failure 7/43(16%) versus 4/42(10%) versus 5/42(12%), p = 0.64, insertion duration median [IQR] 2.8 [1.8-4.8] versus 2.8 [1.7-3.7] versus 2.8 [1.7-4.3] min, p = 0.68 and insertion pain VNRS mean {SD} 4.2 {2.5} versus 3.4 {2.3} versus 3.6 {2.2}, p = 0.26, insertion to delivery interval 26.0 {9.7} versus 25.6 {9.1} versus 22.8 {7.4} h, p = 0.45, and spontaneous vaginal delivery 20/43 (45%) versus 23/42(55%) versus 25/42(60%), p = 0.48 for 16F versus 22F versus 28F arms, respectively. Pairwise comparisons were not different.

    CONCLUSION: Foley catheter 16F versus 22F versus 28F resulted in similar digital insertion performance in the dorsal recumbent position for unripe cervix labor induction.

    PURPOSE: To assess the association of serum leptin and its receptor (SLeptinR) with the risk of gestational diabetes mellitus (GDM) and to evaluate the longitudinal circulation of these peptides in pregnancy.

    METHODS: This study consisted of 53 subjects diagnosed with GDM and 43 normal glucose tolerance (NGT) pregnant women. Serum leptin and SLeptinR were measured at 24-28 weeks, prior and after delivery, and post-puerperium.

    RESULTS: Lower levels of leptin and SLeptinR were observed in GDM compared to NGT. Leptin [OR 0.97 (95% CI 0.94-1.0)] and SLeptinR [OR 0.86 (95% CI 0.79-0.93]) were inversely associated with GDM. Participants in the lowest tertile for leptin and SLeptinR had a 2.8-fold (95% CI 1.0-7.6) and a 5.7-fold (95% CI 1.9-17.3) higher risk of developing GDM compared with the highest tertile, respectively. These relationships were attenuated after adjustment for covariates. In both the groups, peak leptin was observed at 24-28 weeks, decreasing continuously during pregnancy (p > 0.05) and after delivery (p

    OBJECTIVE: To evaluate immediate oxytocin and early amniotomy compared with delayed amniotomy after Foley catheter cervical ripening in multiparous women on intervention-to-delivery interval.

    METHODS: This randomized trial was conducted in Malaysia in 232 term multiparous women with balloon catheter-ripened cervixes (dilatation ≥3 cm), singleton fetus, cephalic presentation with intact membranes, and reassuring fetal heart rate tracing. They were randomized to immediate titrated intravenous oxytocin infusion and early amniotomy (116) or delayed amniotomy after 4 h of oxytocin (116). Primary outcome was intervention (oxytocin initiation)-to-delivery interval.

    RESULTS: Oxytocin-to-delivery intervals were a median of 4.99 h (interquartile range [IQR], 3.21-7.82 h) versus 6.23 h (IQR, 4.50-8.45 h) (P

    Beta-thalassemia is the most-common genetic disorder of hemoglobin synthesis in Malaysia, and about 4.5% of the population are heterozygous carriers of the disorder. Prenatal diagnosis was performed for 96 couples using the Amplification Refractory Mutation System and Gap-Polymerase Chain Reaction. We identified 17 beta-globin defects-initiation codon for translation (T-G), -29 (A-G), -28 (A-G), CAP +1 (A-C), CD 8/9 (+G), CD 15 (G-A), CD 17 (A-T), CD 19 (A-G), Hb E (G-A), IVS1-1 (G-T), IVS1-5 (G-C), CD 41/42 (-CTTT), CD 71-72 (+A), IVS2-654 (CT), poly A(A-G), 100-kb Ggamma(Agammadeltabeta) degrees and 45-kb Filipino deletions. The 192 beta-alleles studied comprised Chinese (151 patients), Malay (21), Orang Asli from East Malaysia (15), Filipino (1), Indian (1), Indonesian Chinese (2), and Thai (1). In the Chinese, 2 beta-globin defects at CD 41/42 and IVS2-654 were responsible for 74% of beta-thalassemia. beta-mutations at CD 19, IVS1-1 (G-T), IVS1-5, poly A, and hemoglobin E caused 76% of the hemoglobin disorders in the Malays. The Filipino 45-kb deletion caused 73.3% of bthalassemia in the Orang Asli. Using genomic sequencing, the rare Chinese beta-mutation at CD 43 (G-T) was confirmed in 2 Chinese, and the Mediterranean mutation IVS1-1 (G-A) was observed in a Malay beta-thalassemia carrier. The beta-globin mutations confirmed in this prenatal diagnosis study were heterogenous and 65 (68%) couples showed a different globin defect from each other. The use of specific molecular protocols has allowed rapid and successful prenatal diagnosis of beta-thalassemia in Malaysia.

    OBJECTIVE: To compare Foley catheter and controlled-release dinoprostone vaginal insert on induction-to-delivery interval and maternal satisfaction in women with one previous cesarean delivery.

    METHODS: This randomized controlled trial was conducted at the University Malaya Medical Center, Kuala Lumpur, Malaysia, from December 12, 2018, to May 28, 2019. A total of 78 term women scheduled for labor induction with one previous cesarean delivery who had ripe cervixes, singleton gestation, cephalic presentation, intact membranes, and reassuring cardiotocogram were randomized to Foley catheter or dinoprostone insert. The primary outcome was induction-to-delivery interval (in hours) and the secondary outcomes included maternal satisfaction on birth experience (assessed by 100-mm visual analog scale).

    RESULTS: Induction-to-delivery intervals were as follows: median 33.5 h (interquartile range [IQR], 26.1-36.2 h) versus 23.5 h (IQR, 12.7-34.5 h) (P = 0.004), and maternal satisfaction on birth process 100-mm visual analog scale was 80 mm (IQR, 64-88 mm) versus 82 mm (IQR, 67-88 mm) (P = 0.919) for the Foley and controlled-release dinoprostone arms, respectively. Cesarean delivery rates were 23 of 39 (59%) versus 20 of 39 (51%) (relative risk, 1.15 [95% confidence interval, 0.77-1.72]) (P = 0.496) and trial device insertion to removal time mean ± standard deviation was 20.1 ± 7.1 h versus 14.2 ± 7.3 h (P = 0.001) for Foley versus controlled-release dinoprostone, respectively.

    CONCLUSION: In term women after one previous cesarean delivery with unripe cervixes, controlled-release dinoprostone vaginal insert compared with Foley catheter shortens the induction-to-delivery interval but maternal satisfaction was not significantly increased.

    CLINICAL TRIAL REGISTRATION: This study was registered with ISRCTN on November 30, 2018, with trial identification number: ISRCTN16957529 (https://doi.org/10.1186/ISRCTN16957529). The first participant was recruited on December 12, 2018.

    BACKGROUND: A prolonged second stage of labor increases the risk of severe perineal laceration, postpartum hemorrhage, operative delivery, and poor Apgar score. The second stage is longer in nulliparas. Maternal pushing during the second stage of labor is an important contributor to the involuntary expulsive force developed by uterine contraction to deliver the fetus. Preliminary data indicate that visual biofeedback during the active second stage hastens birth.

    OBJECTIVE: This study aimed to evaluate if visual feedback focusing on the perineum reduced the length of the active second stage of labor in comparison with the control.

    STUDY DESIGN: A randomized controlled trial was conducted in the University Malaya Medical Centre from December 2021 to August 2022. Nulliparous women about to commence the active second stage, at term, with singleton gestation, reassuring fetal status, and no contraindication for vaginal delivery were randomized to live viewing of the maternal introitus (intervention) or maternal face (sham/placebo control) as visual biofeedback during their pushing. A video camera Bluetooth-linked to a tablet computer display screen was used; in the intervention arm, the camera was focused on the introitus, and in the control arm, on the maternal face. Participants were instructed to watch the display screen during their pushing. The primary outcomes were the intervention-to-delivery interval and maternal satisfaction with the pushing experience assessed using a 0-to-10 visual numerical rating scale. Secondary outcomes included mode of delivery, perineal injury, delivery blood loss, birthweight, umbilical cord arterial blood pH and base excess at birth, Apgar score at 1 and 5 minutes, and neonatal intensive care unit admission. Data were analyzed with the t test, Mann-Whitney U test, chi-square test, and Fisher exact test, as appropriate.

    RESULTS: A total of 230 women were randomized (115 to intervention and 115 to control arm). The active second stage duration (intervention-to-delivery interval) was a median (interquartile range) of 16 (11-23) and 17 (12-31) minutes (P=.289), and maternal satisfaction with the pushing experience was 9 (8-10) and 7 (6-7) (P

    BACKGROUND: Induction of labor in women with 1 previous cesarean delivery and unripe cervices is a high-risk process, carrying an increased risk of uterine rupture and the need for cesarean delivery. Balloon ripening is often chosen as prostaglandin use is associated with an appreciable risk of uterine rupture in vaginal birth after cesarean delivery. A shorter duration of placement of the balloon typically expedites delivery; however, this has not been evaluated in induction of labor after 1 previous cesarean delivery.

    OBJECTIVE: This study aimed to compare Foley balloon catheter placement for 6 vs 12 hours in induction of labor after 1 previous cesarean delivery.

    STUDY DESIGN: A randomized controlled trial was conducted in a university hospital in Malaysia from January 2022 to February 2023. Eligible women with 1 previous cesarean delivery admitted for induction of labor were enrolled. Participants were randomized after balloon catheter insertion for 6 or 12 hours of passive ripening before balloon deflation and removal to check cervical status for amniotomy. The primary outcome was the induction of labor to delivery interval. The secondary outcomes were largely derived from the core outcome set for trials on induction of labor (Core Outcomes in Women's and Newborn Health [CROWN]). The Student t test, Mann-Whitney U test, chi-square test, and Fisher exact test were used as appropriate for the data.

    RESULTS: Overall, 126 women were randomized, 63 to each intervention. The mean induction of labor to delivery intervals were 23.0 (standard deviation, ±8.9) in the 6-hour arm and 26.6 (standard deviation, ±7.1) in the 12-hour arm (mean difference, -3.5 hours; 95% confidence interval, -6.4 to -0.7; P=.02). The median induction of labor (Foley balloon catheter insertion) to Foley balloon catheter removal intervals were 6.0 hours (interquartile range, 6.0-6.3) in the 6-hour arm and 12.0 hours (interquartile range, 12.0-12.5) in the 12-hour arm (P

    BACKGROUND: A majority of pregnant women experience sleep disruption during pregnancy, especially in the third trimester. Lack of sleep is associated with preterm birth, prolonged labor and higher cesarean section rate. Six or less hours of night sleep in the last month of pregnancy is associated with a higher rate of caesarean births. Eye-masks and earplugs compared to headband improve night sleep by 30 or more minutes. We sought to evaluate eye-mask and earplugs compared to sham/placebo headbands on spontaneous vaginal delivery.

    METHODS: This randomized trial was conducted from December 2019-June 2020. 234 nulliparas, 34-36 weeks' gestation with self-reported night sleep

    OBJECTIVE: To evaluate 4-point per day self-monitoring of blood glucose (SMBG) every 2 weeks compared with every week.

    METHODS: A total of 104 patients with lifestyle-controlled gestational diabetes (GDMA1) were randomized to 2-weekly or weekly 4-point per day (fasting on awakening and 2-h post-meals) SMBG. Primary outcome was the change in glycated hemoglobin (HbA1c) level from enrollment to 36 weeks of pregnancy across trial arms. The non-inferiority margin was an HbA1c increase of 0.2%.

    RESULTS: The mean difference for change in HbA1c from enrollment to 36 weeks was 0.003% (95% confidence interval [CI] -0.098% to +0.093%), within the 0.2% non-inferiority margin. The change in HbA1c level increased significantly within both trial arms-0.275% ± 0.241% (P
