Background: COVID-19 is an emerging global pandemic with potential adverse effects during pregnancy. This study aimed to determine the adverse maternal and foetal outcomes due to COVID-19 infection. We also compared maternal and neonatal outcomes with regard to the timing of diagnosis (first and second trimester vs. third and fourth trimester); early COVID-19 (stage I and II) vs. severe-stage COVID-19 (III, IV, and V); and lastly, women who were partially vaccinated vs. unvaccinated. Methods: This was a retrospective study conducted in HCTM from January 2021 to January 2022. All pregnant women admitted for COVID-19 infections were recruited. The patients’ records were traced. Adverse maternal and neonatal outcomes were documented and analysed. Results: There were 172 pregnant women recruited into this study. We excluded twenty-four patients with incomplete data and nine women who delivered elsewhere. The final 139 patients were available for data analysis. The majority of women were in their third trimester of pregnancy (87.8%); however, only 5.0% and 7.2% were in the first and second trimesters, respectively. The study population had a median BMI of 29.1 kg/m2 and almost half of them had never received a COVID-19 vaccination. A sub-analysis of data concerning adverse maternal and foetal outcomes comparing early vs. severe stages of COVID-19 infection showed that severe-stage disease increased the risk of preterm birth (54.5% vs. 15.4%, p < 0.001) and preterm birth before 34 weeks (31.9% vs. 2.6%, p < 0.001) significantly. The severe-stage disease also increased NICU admission (40.9% vs. 15.4%, p = 0.017) with lower birth weight (2995 g vs. 2770 g, p = 0.017). The unvaccinated mothers had an increased risk of preterm birth before 34 weeks and this was statistically significant (11.6% vs. 2.9%, p = 0.048). Conclusions: Adverse pregnancy outcomes such as ICU admission or patient death could occur; however, the clinical course of COVID-19 in most women was not severe and the infection did not significantly influence the pregnancy. The risk of preterm birth before 34 weeks was higher in a more severe-stage disease and unvaccinated mother. The findings from this study can guide and enhance antenatal counselling of women with COVID-19 infection, although they should be interpreted with caution in view of the very small number of included cases of patients in the first and second trimesters.

To investigate factors associated with outcome of second twin during labour. 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. 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. 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.

We investigated if vitamin D is independently associated with hyperglycaemia in gestational diabetes mellitus (GDM). Serum 25 hydroxy vitamin D (25OHD), fasting blood glucose (FBG), HbA1c, fructosamine, insulin sensitivity (QUICKI equation), body mass index, clothing style and outdoor activity were measured in 58 pregnant women with GDM during the third trimester. 25OHD was also measured in 20 women with normal pregnancies. There was no significant difference in mean 25OHD concentrations between GDM (14.43 ± 5.27 ng/ml) and normal (15.45 ± 5.29 ng/ml) pregnancies, p =.354. However, a higher percentage of GDM subjects had 25OHD concentration <19.8 ng/ml (86 versus 65%, p =.003). 25OHD did not correlate with FBG, HbA1c, fructosamine, insulin sensitivity or insulin dosage (p >.05). On multivariate analysis, only ethnicity (p =.006) and outdoor activity (p =.004) were associated with 25OHD. We conclude that the lower 25OHD levels in our GDM patients were related to ethnicity and outdoor activity (Study FF-2017-111, National University of Malaysia, 16 March 2017). What is already known on this subject? Vitamin D deficiency in pregnancy is widespread and particularly in certain ethnic groups. Low vitamin D levels may be an aetiological factor for gestational diabetes mellitus (GDM) but previous studies provide conflicting results perhaps due to confounding factors. What do the results of this study add? In this study of pregnant women with GDM from different ethnic backgrounds, we analysed serum 25-hydroxy vitamin D (25OHD) levels together with other confounding factors, that is, body mass index, ethnicity and sunlight exposure. Furthermore, instead of using consensus values, we determined cut-offs for different vitamin D status from normal pregnancies matched for gestational age and ethnicity. We found that a higher percentage of GDM subjects had lower vitamin D status but there was no correlation with hyperglycaemia or insulin sensitivity. The study showed that lower vitamin D levels in GDM was associated with ethnicity and less outdoor activity. What the implications are of these findings for clinical practice and/or further research? In GDM patients, low vitamin D levels may be modifiable by supplementation or lifestyle change. Longitudinal studies are needed to determine whether this would impact on the occurrence of GDM.

This study was to assess the relationship between late pregnancy haemoglobin A1C (HbA1C) at 29-30 weeks of gestation and adverse pregnancy outcomes (APOs) in 272 pregnant women with pre-existing diabetes. HbA1C ≥6.1% was associated with significantly increased risk of preterm delivery, Caesarean section, large for gestational age (LGA), neonatal respiratory distress, neonatal hypoglycaemia, and composite adverse neonatal outcome (p < .05). The risk of pre-eclampsia increased significantly at the lower HbA1C cut-off of > 5.6% (p = .039). Reduction of HbA1C cut-off from 6.1% to 5.6% improved the sensitivity but reduced the specificity for prediction of APOs. Overall, the receiver operating characteristic (ROC) curves demonstrated the moderate predictive value of late pregnancy HbA1C for APOs. In conclusion, elevated late pregnancy HbA1C levels at 29-30 gestational weeks had a negative impact on APOs in pregnant women with pre-existing diabetes. However, HbA1C cut-off levels of neither ≥6.1% nor >5.6% were ideal for predicting APOs. Impact statement: What is already known on this subject: Poorly controlled diabetes is associated with adverse pregnancy outcomes (APOs). Periconceptual haemoglobin A1C (HbA1C) correlates well with the risk of foetal anomaly but is not predictive of APOs at time of delivery. New evidence suggested that late pregnancy HbA1C is predictive of APOs but the definitions of a late pregnancy gestational week and target HbA1C cutpoint remain in doubt. What the results of this study add: This study investigated the relationship between late pregnancy HbA1C levels at 29-30 weeks of gestation and the APOs among pregnant women with pre-existing diabetes. Late pregnancy HbA1C ≥ 6.1% correlated with the risk of APOs but the increased risk of pre-eclampsia only became significant at the lower cut-off of >5.6%. Reducing HbA1C cut-off from 6.1% to 5.6% improved the sensitivity but reduced the specificity for prediction of APOs. Overall, late pregnancy HbA1C had a moderate predictive value for APOs. What the implications are of these findings for clinical practice and/or further research: HbA1C cut-off levels of neither ≥6.1% nor >5.6% were ideal in predicting APOs among pregnant women with pre-existing diabetes. As HbA1C levels tend to drop in pregnancy, caution should be taken when interpreting HbA1C in pregnancy. More multi-centred studies are required to explore the respective glycaemic target for each APO and to determine the ideal timing for late pregnancy HbA1C measurement. [ABSTRACT FROM AUTHOR]

This was a prospective observational study to determine the predictive factors for a successful vaginal birth after caesarean section (VBAC) and to develop a relevant antenatal scoring system. Patients with one previous caesarean section were included in this study. All data including maternal demographics, obstetric history, pregnancy progress and outcomes were collected and analysed. A total of 142 out of the 186 women (76.3%) had successful VBAC. History of previous vaginal delivery and non-recurrent indications for previous caesarean section were the significant predictive factors for a successful VBAC. Five variables for our scoring tool were selected. By using a proposed mean score of 4 out of 7, the scoring system had a sensitivity of 81.0%, specificity of 52.3% and a positive predictive value of 84.6%. VBAC antenatal scoring system was potentially a useful predictive tool in antenatal counselling. Impact statement What is already known on this subject: Planned vaginal birth after caesarean section (VBAC) is an important strategy to limit the overall caesarean section rate, which is related to maternal morbidities. However, trial of vaginal delivery does involve potential complications including scar dehiscence, postpartum haemorrhage and emergency hysterectomy. What the results of this study add: Clinical predictors of a successful VBAC include non-recurrent indications for the previous caesarean section, previous vaginal delivery, spontaneous onset of labour and birthweight less than 4kg. There were multiple screening tools developed to predict the likelihood of successful VBAC. These scoring systems involved various variables such as age, ethnicity, Bishop's score and previous caesarean indication. We had prospectively developed an antenatal scoring system based on five variables. Our result showed that patient with a score of four and above will have around 85% chance of successful VBAC. What the implications are of these findings for clinical practice and/or further research: We have also found that, estimated foetal weight based on ultrasound scan is a potential predictor for successful VBAC. This simple scoring method will be useful in-patient counselling regarding mode of delivery after one previous caesarean section. A multicentre study involving large cohort of patients is ideal to validate our scoring system. [ABSTRACT FROM AUTHOR]

Introduction: It is well known that preterm birth (PTB) contributes to perinatal mortality and long-term morbidity. Elevated serum ferritin levels have been frequently reported in PTB compared to term births; however, most studies had blood samples taken during the peripartum period. We aim to evaluate the relationship between antenatal serum ferritin levels and PTB. Methods: A retrospective study of pregnant women delivered at our hospital between January 2013 and December 2020 was conducted. Demographic data, medical history, gestation, and blood ferritin results were retrieved from the hospital and laboratory information system. Patients with maternal serum ferritin measured antenatally who were not documented to have chronic diseases, infection, iron disorders, multiple gestations, and uterine or cervical anomalies were included in the analysis. We compared the preterm and term groups' ferritin levels and other risk factors. Results: Among 202 recruited women, 27 (14.4%) had spontaneous PTB. Most ferritin measurements (80%) were taken during the third trimester. There was no significant difference in the median ferritin levels between PTBs (15.81µg/L, IQR 10.09 - 32.41 µg/L) and term births (16.11µg/L, IQR 9.09 - 34.38 µg/L), P=0.801. However, ferritin levels in the second trimester nearly doubled that in the first trimester in the PTB group. PTB was associated with more cases of preeclampsia (P=0.003), a history of antepartum haemorrhage (p=0.040) and premature rupture of membrane status (P<0.001). Conclusion: Despite the elevation of ferritin levels in the second trimester, there is no significant association between maternal antenatal ferritin levels and PTB. [ABSTRACT FROM AUTHOR]

Introduction Gestational diabetes mellitus (GDM) poses a significant health concern due to the numerous risks it presents to both the mother and fetus. While serum ferritin typically declines in cases of iron deficiency anemia, which is common during pregnancy, it may increase in the presence of inflammation. This study aims to evaluate the significance of serum ferritin in the context of GDM, considering its multifaceted role in these interconnected conditions. Methodology This cross-sectional study included pregnant women attending an obstetrics clinic for an oral glucose tolerance test at Hospital Canselor Tuanku Muhriz in Kuala Lumpur, Malaysia. With consent, demographic data, risk factors for GDM, and blood samples were collected. Blood samples were analyzed for serum ferritin, fasting blood glucose, two-hour post-glucose levels, and full blood count. The assessment of risk factors for GDM and the diagnosis of GDM adhered to Malaysian guidelines. The Mann-Whitney U test was employed to compare variables between the GDM and non-gestational diabetes mellitus (non-GDM) groups. Additionally, univariate and multivariate regression analyses were conducted to investigate the role of serum ferritin in GDM. All analyses were performed using IBM SPSS Statistics for Windows, Version 28.0 (Released 2021; IBM Corp., Armonk, NY, USA), with statistical significance set at p < 0.05. Results Among 172 pregnant women with an average gestational age of 23.6 weeks, the incidence of GDM was higher in those with risk factors (84.8%) compared to non-GDM participants (75.5%). Women with GDM had a slightly higher mean serum ferritin level (50.24 ± 29.00 ng/mL) than those without GDM (45.00 ± 58.69 ng/mL). However, ferritin levels did not significantly differ between the GDM and non-GDM groups (p = 0.669) or between those with and without risk factors (p = 0.374). While a higher BMI (OR: 0.832, p = 0.017) and ferritin (OR: 1.022, p = 0.031) levels independently predicted GDM, the predictive value of ferritin was borderline significant when combined with glucose tests (area under the curve = 0.689, p = 0.051). Conclusions Higher maternal serum ferritin levels in the mid-trimester are associated with increased BMI and GDM. However, maternal serum ferritin is most effective at predicting the incidence of GDM when used alongside standard glucose measurements, especially in women with elevated BMI., Competing Interests: Human subjects: Consent for treatment and open access publication was obtained or waived by all participants in this study.

Cerebral arteriovenous malformation (AVM) is a rare entity with an estimated prevalence of 0.01-0.05% in the general population. We reviewed hospital obstetric records during 2010-2017 and reported a case series of six patients with cerebral AVM in pregnancy, of which five patients had successful pregnancy, and one maternal mortality., (© 2019 The Author(s).

Purpose: To determine the maternal and fetal outcomes of successful external cephalic version (ECV) as well as factors predicting vaginal birth., Methods: The ECV data over a period of three years at Universiti Kebangsaan Malaysia Medical Centre (UKMMC) between 1 September 2008 and 30 September 2010 was reviewed. Sixty-seven patients who had successful ECV were studied and reviewed for maternal, fetal, and labour outcomes. The control group comprised patients with cephalic singletons of matching parity who delivered following the index cases., Results: The mean gestational age at ECV was 263 ± 6.52 days (37.5 weeks ± 6.52 days). Spontaneous labour and transient cardiotocographic (CTG) changes were the commonest early adverse effects following ECV. The reversion rate was 7.46%. The mean gestational age at delivery of the two groups was significantly different (P = 0.000) with 277.9 ± 8.91 days and 269.9 ± 9.68 days in the study group and control groups, respectively. The study group needed significantly more inductions of labour. They required more operative deliveries, had more blood loss at delivery, a higher incidence of meconium-stained liquor, and more cord around the neck. Previous flexed breeches had a threefold increase in caesarean section rate compared to previous extended breeches (44.1% versus 15.2%, P = 0.010). On the contrary, an amniotic fluid index (AFI) of 13 or more is significantly associated with a higher rate of vaginal birth (86.8% versus 48.3%, P = 0.001)., Conclusions: Patients with successful ECV were at higher risk of carrying the pregnancy beyond 40 weeks and needing induction of labour, with a higher rate of caesarean section and higher rates of obstetrics complications. Extended breech and AFI 13 or more were significantly more likely to deliver vaginally postsuccessful ECV. This additional information may be useful to caution a patient with breech that ECV does not bring them to behave exactly like a normal cephalic, so that they have more realistic expectations. However, these predictive factors needed further confirmation and hopefully, in the future, they would be able to further enhance counselling prior to ECV.

Purpose: Malaysia a dengue endemic country with dengue infections in pregnancy on the rise. The present study was aimed at determining dengue seroprevalence (IgG or IgM) during pregnancy and its neonatal transmission in dengue seropositive women., Methods: Maternal with paired cord blood samples were tested for dengue antibodies (IgG and IgM) using an enzyme-linked immunosorbent assay (ELISA). Maternal age, parity, occupation, ethnic group, and gestational age were recorded. Data on neonatal Apgar score and admissions to the Neonatal Intensive Care Unit (NICU) were analyzed., Results: Out of 358 women recruited, about 128 (35.8%) patients were seropositive. Twelve patients (3.4%) had recent infections (IgM positive) and another 116 women (32.4%) were with past infections (IgG positive). All babies born to seropositive mothers had positive IgG paired cord blood; however, no IgM seropositivity was observed. All neonates had good Apgar scores and did not require NICU admission., Conclusion: In this study, 35.8% pregnant women were found to be dengue seropositive. However, transplacental transfer of IgG antibodies had no detrimental effect on the neonatal outcomes.

Pheochromocytoma during pregnancy is potentially disastrous to the mother and fetus. Its ambiguous presentation is often mistaken for pre-eclampsia, although it may imitate other problems during pregnancy. Early diagnosis and timely, appropriate management reduces possible maternal and fetal complications. We identified a case of pheochromocytoma during pregnancy; the condition was initially diagnosed as pre-eclampsia complicated with gestational diabetes. Surgical intervention via left adrenalectomy was successfully performed in the second trimester. After surgery, all of the patient's medical problems nearly subsided and she did not require further treatment. However, her fetus displayed restricted intrauterine growth, and the patient eventually had premature delivery via a caesarean section. A multidisciplinary team to identify and treat pheochromocytoma is mandatory to ensure optimal conditions for tumour removal and to anticipate any possible catastrophic events.
