Second twin outcome at birth: retrospective analysis in a single tertiary centre in Malaysia.

OBJECTIVES: To investigate factors associated with outcome of second twin during labour. METHODS: The study was a retrospective cohort study in a single tertiary centre in Malaysia from 2014 until 2018 involving all twin pregnancies delivered at or more than 24 weeks of gestation. RESULTS: Total of 409 twin pregnancies were included. Dichorionic twin comprises of 54.5 % (n=223) and 45.5 % (n=186) are monochorionic. Women with dichorionic pregnancies are significantly older (p<0.001), have more pre-existing medical disorders (p=0.011) and fetal structural anomalies (p=0.009). Monochorionic pregnancies are significantly more amongst Malay (p=0.01) and conceived spontaneously (p<0.001). There are significantly more fetuses both in cephalic presentation (p=0.026), birthweight discrepancy more than 20 % (p=0.038) and shorter mean inter-twin delivery duration (p=0.048) in monochorionic pregnancies. Second twin delivered with Apgar score <7 is significantly more in dichorionic pregnancies (p=0.006). The second twin is associated with lower birthweight, small for gestational age and arterial cord pH<7.25. Within the group of women who delivered both fetuses vaginally, there was significantly more second twins with intertwin delivery duration less than 30 min who were delivered vaginally without instrumentation (p=0.018). There was significantly more second twin with intertwin delivery duration of 30 min and more with arterial cord pH<7.25 (p=0.045). Those who delivered spontaneously had inter-twin delivery duration within 15-29 min. The outcome of second twin is not influenced by type of twin, gestational age at delivery, inter-twin delivery duration, mode of delivery and presentation at birth. CONCLUSIONS: The neonatal outcome for the second twin at birth is not influenced by type of twin, gestational age at delivery, inter-twin delivery duration, mode of delivery and presentation at birth in a cohort managed with non-active management of the second twin in Malaysia.

Comparison of Pregnancy Outcome between 4 and 6 cm Cervical os Dilatation to Demarcate Active Phase of Labour: A Cross-Sectional Study.

This is a cross-sectional study comparing pregnancy outcomes between participants with 4 and 6 cm of cervical os dilatation at the diagnosis of the active phase of labour. It was conducted in a single tertiary centre involving low-risk singleton pregnancies at or beyond 37 weeks with spontaneous onset of labour. A total of 155 participants were recruited, 101 in group 1 (4 cm) and 54 in group 2 (6 cm). Both groups were similar in mean maternal age, mean gestational age at delivery, ethnicity, median haemoglobin level at delivery, body mass index, and parity. There were significantly more participants in group 1 who needed oxytocin augmentation (p < 0.001) for the longer mean duration (p = 0.015), use of analgesia (p < 0.001), and caesarean section rate (p = 0.002). None of the women had a postpartum haemorrhage or a third- or fourth-degree perineal tear, and none of the neonates required admission to the neonatal intensive care unit. There were significantly more nulliparas who had a caesarean section as compared to multiparas. A cervical os dilatation of 6 cm reduces the risk of caesarean section by 11% (95% CI, 0.01-0.9) and increases three times more the need for analgesia (AOR = 3.44, 95% CI, 1.2-9.4). In conclusion, the demarcation of the active phase of labour at a cervical os dilatation of 6 cm is feasible without an increase in maternal or neonatal complications.

Cervical dilatation at diagnosis of active phase of labour determines the mode of delivery and peripartum outcomes: a retrospective study in a single tertiary centre in Malaysia.

BACKGROUND: There is an increasing trend of Caesarean section rate in Malaysia. Limited evidence demonstrated the benefits of changing the demarcation of the active phase of labour. METHODS: This was a retrospective study of 3980 singletons, term pregnancy, spontaneous labouring women between 2015 and 2019 comparing outcomes between those with cervical dilation of 4 versus 6 cm at diagnosis of the active phase of labour. RESULTS: A total of 3403 (85.5%) women had cervical dilatation of 4 cm, and 577 (14.5%) at 6 cm upon diagnosis of the active phase of labour. Women in 4 cm group were significantly heavier at delivery (p = 0.015) but significantly more multiparous women were in 6 cm group (p < 0.001). There were significantly fewer women in the 6 cm group who needed oxytocin infusion (p < 0.001) and epidural analgesia (p < 0.001) with significantly lower caesarean section rate (p < 0.001) done for fetal distress and poor progress (p < 0.001 both). The mean duration from diagnosis of the active phase of labour until delivery was significantly shorter in the 6 cm group (p < 0.001) with lighter mean birth weight (p = 0.019) and fewer neonates with arterial cord pH < 7.20 (p = 0.047) requiring neonatal intensive care unit admissions (p = 0.01). Multiparity (AOR = 0.488, p < 0.001), oxytocin augmentation (AOR = 0.487, p < 0.001) and active phase of labour diagnosed at 6 cm (AOR = 0.337, p < 0.001) reduced the risk of caesarean delivery. Caesarean delivery increased the risk of neonatal intensive care admission by 27% (AOR = 1.73, p < 0.001). CONCLUSIONS: Active phase of labour at 6 cm cervical dilatation is associated with reduced primary caesarean delivery rate, labour intervention, shorter labour duration and fewer neonatal complications.

Amniotomy and early oxytocin infusion vs amniotomy and delayed oxytocin infusion for labour augmentation amongst nulliparous women at term: A randomised controlled trial.

OBJECTIVE: to compare the effect of amniotomy with early vs delayed oxytocin infusion on successful vaginal delivery. DESIGN: randomised controlled trial of nulliparous women with spontaneous labour at term. SETTING: labour suite of a university teaching hospital in Kuala Lumpur, Malaysia. PARTICIPANTS: 240 women were included (120 randomised into two arms). INTERVENTIONS: the randomisation sequence was generated using a computer randomisation program in two blocks: oxytocin infused early following amniotomy; and oxytocin infused 2 h after amniotomy. MEASUREMENTS AND FINDINGS: labour duration, mode of delivery, oxytocin dosage used, uterine hyperstimulation, postpartum haemorrhage, Apgar score and admission to the neonatal intensive care unit were recorded. No differences in vaginal delivery rate (62.9% vs 70.9%; p = 0.248) and second-stage labour were found between the early and delayed oxytocin infusion groups (21.2 ± 18.3 min vs 25.5 ± 19.9 min; p = 0.220). The mean interval from amniotomy to vaginal delivery was significantly shorter for the early group (5.8 ± 1.7 h vs 7.0 ± 1.9 h; p = 0.001), and more women in the early group delivered during/before the planned review at 4 h after amniotomy (53.6% vs 10.6%; p<0.001). Maximum oxytocin usage was lower in the early group (5.6 ± 4.4 mL/hour vs 6.8 ± 5.3 mL/hour; p = 0.104). KEY CONCLUSIONS: early oxytocin augmentation following amniotomy could be employed in low-risk primigravida, given that it is associated with a shorter labour duration without jeopardising maternal or neonatal outcomes. IMPLICATIONS FOR PRACTICE: low-risk primigravida benefit from early oxytocin infusion following amniotomy, and this can be offered as an additional practice in labour room care.

Use of the Arabin pessary in women at high risk for preterm birth: long-term experience at a single tertiary center in Malaysia.

BACKGROUND: Spontaneous preterm birth is a global issue that contributed to perinatal morbidities and mortalities worldwide. The study aimed to describe the experience at UKM Medical Center in managing women at high risk for spontaneous preterm birth using the Arabin pessary. METHODS: This is a retrospective observational study involving 58 pregnancies from 1st January 2013 to 31st December 2019. Inclusion criteria were previous mid-trimester miscarriage and/or preterm birth, previous cervical surgery or short cervical length on routine sonogram. The demographic data, characteristics of each pregnancy and details of outcomes and management were described. RESULTS: The majority of women were Malay with mean age and body mass index of 32.9 ± 4.2 years and 27.1 ± 6.3 kg/m2 respectively. The most frequent indications for Arabin pessary insertion were previous mid-trimester miscarriage (46.4%) and early preterm birth (17.2%). A total of 73.4% of these women had the pessary inserted electively at a mean cervical length of 31.6 ± 9.1 mm at median gestation of 15.0 weeks. They were managed as outpatient (56.9%), inpatient (24.1%) or mixed (19.0%) with combination of progestogen (81.0%) and 53.4% received antenatal corticosteroids. Spontaneous preterm birth at or more than 34 weeks gestation occurred in 74.1% with birthweight at or more than 2000 g (82.4%). Despite cervical funneling in 12 women (20.7%), 66.7% delivered at or later than 34 weeks gestation and 2 (16.7%) resulted in miscarriage. CONCLUSIONS: Insertion of the Arabin pessary is beneficial to prevent spontaneous preterm birth in pregnant women who are at high risk. In particular, early insertion and close monitoring allows the best possible outcomes. TRIAL REGISTRATION: This study was retrospectively registered with ClinicalTrials.gov ( NCT04638023 ) on 20/11/2020.

Correlation between Oral Glucose Tolerance Test Abnormalities and Adverse Pregnancy Outcomes in Gestational Diabetes: A Cross-Sectional Study.

Gestational diabetes mellitus (GDM) is associated with maternal and neonatal complications. We aimed to evaluate the relationship between the abnormalities of the oral glucose tolerance test (OGTT) and adverse pregnancy outcomes. This was a retrospective study of GDM patients over a five-year period in a Malaysian tertiary center. The diagnosis of GDM was based on the National Institute for Health and Care Excellence (NICE) guideline. The data on patients' demographics, OGTT results, GDM treatment, and pregnancy outcomes were analyzed. A total of 1105 women were included in the final analysis. The percentage of women with isolated abnormal fasting glucose, isolated two-hour abnormality, and both abnormal values were 4.8%, 87.1%, and 8.1%, respectively. Women with both OGTT abnormalities had a higher risk of preeclampsia (odds ratio (OR) 4.73; 95% confidence interval (CI) 1.45-15.41) and neonatal hypoglycemia (OR 8.78; 95% CI 1.93-39.88). Isolated postprandial abnormality was associated with an 80% lesser risk of neonatal hypoglycemia (OR 0.19; 95% CI 0.04-0.87). Both isolated fasting and multiple OGTT abnormalities were associated with insulin therapy. Multiple OGTT abnormalities were a positive predictor of adverse pregnancy outcomes, while isolated postprandial abnormality was associated with a lesser risk of neonatal complication. Further prospective study is essential to validate these findings.

Vaccine hesitancy towards childhood immunisation amongst urban pregnant mothers in Malaysia.

BACKGROUND: Vaccine hesitancy is a complex behaviour which involves various degrees of indecision about specific vaccines or vaccination uptake. Access to antenatal care had been associated with positive vaccine behavior. OBJECTIVE: To determine the prevalence of vaccine hesitancy towards childhood immunisation amongst urban pregnant mothers and the associated socio-demographic factors. METHODS: A cross-sectional study was conducted among 1081 women who received antenatal care at a teaching hospital in Kuala Lumpur. Vaccine hesitancy was assessed using the Parent Attitudes about Childhood Vaccines (PACV) Survey in both English and validated Malay versions. The sociodemographic data of the mothers and their partners, source of vaccine information and reasons for hesitancy were analysed. RESULTS: Eighty-six (8.0%) pregnant mothers were vaccine hesitant. Ethnicity, religion, number of children, educational level and employment status were significantly associated with vaccine hesitancy. Multivariable analysis showed that a low level of education was the most significant risk factor (p < 0.001), followed by religion (p = 0.03). Health professionals was the main source of information about vaccine. The non-vaccine hesitant women were more likely to seek information from health professionals, and health books and magazine. Fear of adverse side effects of vaccines was the predominant concern for all participants (58%) whilst fear of vaccination pain, preference for alternative medicine and lack of trust in the pharmaceutical industry were significant reasons given by the vaccine hesitant group. Partners' ethnicity, a low educational level and a low income were significantly associated with vaccine hesitancy amongst pregnant mothers. CONCLUSION: Prevalence of vaccine hesitancy amongst urban Malaysian pregnant women was relatively low. Muslim mothers are less likely to be vaccine hesitant. Educational level of mothers and their partners are the common determinant of vaccine hesitancy amongst antenatal mothers.

Management of bleeding irregularities among etonogestrel implant users: Is combined oral contraceptives pills or nonsteroidal anti-inflammatory drugs the better option?

AIM: This study is to evaluate whether unacceptable bleeding among the etonogestrel implant user could be better alleviated using combined oral contraceptive pills (COCP) or nonsteroidal anti-inflammation drugs (NSAID). METHODS: This is a prospective randomized study for evaluation of 84 etonogestrel implant (Implanon) users with prolonged or frequent bleeding. They were assigned to either receiving a COCP containing 20 mcg ethinyl estradiol/150 mg desogestrel for two continuous cycle or NSAID; mefenamic acid 500 mg TDS for 5 days, 21 days apart for two cycles. Bleeding pattern during the treatment was recorded and analyzed. RESULTS: A total of 32 women (76.2%) in COCP group and 15 women (35.7%) in NSAID group stop bleeding within 7 days after the initiation of treatment which was statistically significant (P < 0.05). The mean duration of bleeding and spotting days in women treated with COCP was significantly lesser compared to NSAID group (7.29 ± 3.16 vs 10.57 ± 4.14 days (P < 0.05). CONCLUSION: We conclude that COCP is more efficient compared to NSAID in managing bleeding irregularities among etonogestrel implant users.

5-Year review on amniocentesis and its maternal fetal complications.

Background Amniocentesis is a well-known invasive procedure which is commonly carried out in the second trimester. The indication for amniocentesis varies throughout countries and centers. Despite providing significant prenatal diagnosis; many maternal and fetal complications have been reported from previous studies. Materials and methods This retrospective study aimed to determine the maternal and fetal complications following amniocentesis. This study involved all patients who underwent amniocentesis from January 2012 until June 2017 in a tertiary centre. Maternal age, parity, premorbid medical conditions, amniocentesis indications, gestational age during amniocentesis, karyotyping results, complications during and post procedure and the fetal outcomes were reviewed and analyzed. Results One hundred and fourteen patients' medical records were reviewed and the majority of patients (50.9%) ranged in age from age 30 to 39 years old with mean age of 34.29 years. Amniocentesis was performed during the second trimester in the majority of patients (71.1%). The indications for amniocentesis in this study were polyhydramnios (7.9%), advanced maternal age (9.6%), risk of Down's syndrome (31.6%), increased risk of Patau syndrome (6.1%), increased risk of Edward's syndrome (4.4%) and abnormal fetal ultrasonography (70.2%). Cytogenetics results of amniocentesis were normal in 82 patients (71.9%). The majority of patients (86.0%) had no complications. Two patients (12.5%) had intrauterine death presumed to be procedural related. Conclusion This 5-year retrospective study on amniocentesis procedure showed that the majority of amniocentesis were safe as 86.0% of the patients were free from any complications. Anticipating its complication is important as there is always a risk even though it is a safe procedure in general.

Congenital complete heart block in pregnancy.

Complete heart block (CHB) is infrequently encountered during pregnancy. Its management requires a multidisciplinary approach involving the obstetrician, cardiologist, anesthetist and neonatologist. It varies from conservative, temporary or permanent pacemaker (PPM) insertion (either during the antenatal, intrapartum or postpartum period). We present the case of a 30-year-old, gravida 2 para 1 at the 36-week period of amenorrhea (POA) with congenital CHB. She was asymptomatic throughout her pregnancy despite having a pulse rate between 40 and 50 beats per minute. She delivered a healthy boy via cesarean section due to breech presentation after a failed external cephalic version. A temporary pacemaker was inserted prior to delivery. However, she required permanent insertion of pacemaker during the postpartum period.

Predictors of postpartum weight retention among urban Malaysian mothers: A prospective cohort study.

BACKGROUND: Women of childbearing age are predisposed to becoming overweight or obese. This study determines the mean, prevalence and factors associated with 6 months postpartum weight retention among urban Malaysian mothers. METHODS: A prospective cohort study was conducted at baseline (after delivery), 2, 4 and 6 months postpartum. From 638 eligible mothers initially recruited, 420 completed until 6 months. Dependent variable was weight retention, defined as difference between weight at 6 months postpartum and pre-pregnancy weight, and weight retention ≥5kg was considered excessive. Independent variables included socio-demographic, history of pregnancy and delivery, lifestyle, practices and traditional postpartum practices. RESULTS: Average age was 29.61±4.71years, majority (83.3%) were Malays, 58.8% (low education), 70.0% (employed), 65.2% (middle income family), 33.8% (primiparous) and 66.7% (normal/instrumental delivery). Average gestational weight gain was 12.90±5.18kg. Mean postpartum weight retention was 3.12±4.76kg, 33.8% retaining ≥5kg. Bivariable analysis showed low income, primiparity, gestational weight gain ≥12kg, less active physically, higher energy, protein, carbohydrate and fat intake in diet, never using hot stone compression and not continuing breastfeeding were significantly associated with higher 6 months postpartum weight retention. From multivariable linear regression analysis, less active physically, higher energy intake in diet, gestational weight gain ≥12kg, not continuing breastfeeding 6 months postpartum and never using hot stone compression could explain 55.1% variation in 6 months postpartum weight retention. CONCLUSION: Women need to control gestational weight gain, remain physically active, reduce energy intake, breastfeed for at least 6 months and use hot stone compression to prevent high postpartum weight retention.

The World Health Organization (WHO) versus The International Association of Diabetes and Pregnancy Study Group (IADPSG) diagnostic criteria of gestational diabetes mellitus (GDM) and their associated maternal and neonatal outcomes.

Background Gestational diabetes mellitus (GDM) is a common medical complication in pregnancy. The aim of this study was to compare the prevalence of GDM using the World Health Organization (WHO) criteria and the International Association of Diabetes and Pregnancy Study Group (IADPSG) criteria in our population. We further compared the incidence of adverse maternal and neonatal outcomes in women diagnosed with GDM using these criteria and determined whether the IADPSG criteria is suitable in our population. Methods This randomized controlled trial was conducted at our antenatal clinic involving 520 patients from 1st February 2015 until 30th September 2017. They were randomized into the WHO and the IADPSG groups. All eligible women underwent a standard oral glucose tolerance test with 75 g glucose, their fasting and 2 h post prandial glucose levels were taken. The primary outcome was the prevalence of GDM. The secondary outcomes were the incidence of primary cesarean section, gestational hypertension or preeclampsia, preterm delivery <37 weeks, fetal macrosomia, neonatal hypoglycemia and shoulder dystocia or birth injury. Results The prevalence of GDM in both groups were similar (37.9% vs. 38.6%). GDM women in the WHO group had a significantly higher incidence of gestational hypertension or preeclampsia (p = 0.004) and neonatal hypoglycemia (p = 0.042). In contrast, GDM women in the IADPSG group had a significantly higher incidence of fetal macrosomia (p = 0.027) and cesarean section (p = 0.012). Conclusion The IADPSG diagnostic criteria for GDM may not be suitable for use in our population as it resulted in women being diagnosed later and being undertreated, thus leading to adverse maternal and neonatal outcomes.

Antenatal calcium intake in Malaysia.

AIM: To determine the adequacy of antenatal calcium intake in Malaysia, and the influencing factors. METHODS: A cross-sectional study was conducted among postnatal women who delivered in two tertiary hospitals. Data were collected from antenatal cards, hospital documents and diet recall on daily milk and calcium intake during pregnancy. SPSS version 19.0 was used for statistical analyses. RESULTS: A total of 150 women were studied. The total daily calcium intake was 834 ± 43 mg (mean ± standard error of the mean), but the calcium intake distribution curve was skewed to the right with a median intake of 725 mg daily. When calcium intake from milk and calcium supplements was excluded, the daily dietary calcium intake was only 478 ± 25 mg. Even with inclusion of milk and calcium supplements, more than a third (n=55 or 36.7%) of the women consumed less than 600 mg calcium in their daily diet. The adequacy of daily calcium intake was not influenced by maternal age, ethnicity, income or maternal job or educational status as well as parity. CONCLUSION: The daily dietary calcium intake of the Malaysian antenatal population is far from adequate without the addition of calcium supplements and milk.

A randomized control trial evaluating the prevalence of obstetrical anal sphincter injuries in primigravida in routine versus selective mediolateral episiotomy.

OBJECTIVE: To evaluate the prevalence of obstetrical anal sphincter injuries (OASIS), which include third and fourth degree perineal tears in primigravida in routine versus selective mediolateral episiotomy. Secondly, to determine the rate of episiotomy in local settings. METHODS: This randomized control trial was carried out in the labor ward of a tertiary hospital of the Universiti Kebangsaan Malaysia Medical Center, Kuala Lumpur, Malaysia between May and October 2009. The trial included 171 primigravida beyond 38 weeks gestation who achieved vaginal delivery, and randomly assigned to selective and routine episiotomy groups. The type of perineal injuries following childbirth among 171 women were evaluated. RESULTS: The overall episiotomy rate from both groups was 76.6%. The prevalence of third degree perineal tears was 3.7% in the routine compared with selective mediolateral episiotomy at 1.1%. There was no occurrence of fourth degree tears in both groups. However, selective mediolateral episiotomy was associated with an increased risk of periurethral and labial injury compared with the routine group (4.5% versus 0%). CONCLUSION: Routine mediolateral episiotomy in primigravida is associated with a higher prevalence of obstetrical anal sphincter injuries. As anal sphincter injuries are known to have morbidities, selective mediolateral episiotomy in primigravida is therefore recommended in the implementation of new delivery practice, and in an attempt to reduce our high episiotomy rate.

Complete mole with a coexistent normal fetus: a case report.

BACKGROUND: The incidence of a coexistent normal fetus is quoted in literature as 1 in 22,000 to 100,000 pregnancies and may be associated with multiple complications including persistent trophoblastic neoplasia. CASE: A 35-year-old woman with a complete mole and a coexistent normal fetus presented with multiple complications but was successfully managed until 30 weeks' gestation and gave birth to a healthy, normal female fetus. After delivery the mother recovered completely with no evidence of persistent trophoblastic disease. CONCLUSION: Although termination of pregnancy is an option chosen by most patients, continuing the pregnancy while optimizing the maternal condition by appropriate management of complications can result in a successful outcome.

Utero-cutaneous fistula after caesarean section secondary to red degeneration of intramural fibroid.

A 33 year-old woman had an emergency caesarean section for retained second twin which was complicated by utero-cutaneous fistula due to red degeneration of intramural fibroid. The utero-cutaneous communication was demonstrated by an examination under anaesthesia using dye test. She then underwent excision of the fistula tract and myomectomy. She recovered well following the surgery. This is the first case of utero-cutaneous fistula where the communication is between the endometrial cavity and skin lesion via a necrotic intramural fibroid following caesarean section. Fistulogram might fail to demonstrate the communication. In highly suspected case, other modalities of investigations could be utilised.

Gestational diabetes mellitus in primigravidae: a mild disease.

This prospective observational study was done to analyse the prevalence of gestational diabetes mellitus (GDM) among primigravidae and its outcome. All healthy primigravidae with singleton pregnancies were offered universal glucose tolerance testing between 16 and 28 weeks gestation. GDM and non GDM groups were managed according to hospital protocol. The antenatal features and pregnancy outcomes were analysed. Out of 616 primigravidae, 113 (18.34%) were GDM with slightly older (27.9 +/- 4.2 versus 26.32 +/- 3.3, p < 0.001) age. The mean fasting and two hours postprandial blood glucose in both groups were 4.99 +/- 1.08 mmol/l, 8.86 +/- 1.41 mmol/l(GDM) and 4.36 +/- 0.43 mmol/l, 5.71 +/- 1.11 mmol/l (Non GDM), respectively. Maternal family history of diabetes mellitus, weight exceeding 80 Kg, polyhydramnios (2.65% versus 0.2%, p = 0.028) and neonatal hyperbilirubinaemia (9.73% versus 2.98%, p = 0.01) occurred significantly more frequent in the GDM group compared to normal. There was no significant difference in other pregnancy outcomes and complications between the two groups. In conclusion GDM in primigravidae was detected at a relatively young age with more frequent maternal family history of DM, weight exceeding 80 Kg, polyhydromnions and neonatal hyperbilirubinaemia. The degree of disease was mild and treatment led to no significant complication.

Advanced abdominal pregnancy resulting from late uterine rupture.

BACKGROUND: Advanced abdominal pregnancy is rare, and one that occurs after uterine rupture with delivery of a viable fetus is exceptional. CASE: A multiparous patient was admitted at 29 weeks of gestation for conservative management of placenta previa. She complained of intermittent abdominal pain, but repeated assessment suggested that both the patient and the fetus were doing well. At 36 weeks, an abdominal pregnancy was diagnosed with radiological features suggestive of uterine rupture. Laparotomy was performed and a healthy infant was delivered. CONCLUSION: Fetal viability was achieved in this case of abdominal pregnancy secondary to uterine rupture after close maternal and fetal surveillance.
