    The neonatal period is being recognized as an important period for the development of patterns of interaction between mother and infant, and infant state has been shown to have a significant impact on mother--infant interactions. A major dimension of infant state, with implications for this interaction and for the development of later behaviour disorders, is the infant's irritability. Research with Navajo, Malay, Chinese and Tamil mothers and infants showed that normal variation in maternal blood pressure during pregnancy was related to newborn irritability as assessed with the Brazelton Scale. This relationship is discussed in terms of possible underlying mechanisms.

    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.

  4. Fulltext Serum Glucose-Dependent Insulinotropic Polypeptide (GIP) and Glucagon-Like Peptide-1 (GLP-1) in association with the Risk of Gestational Diabetes: A Prospective Case-Control Study
    Mosavat M, Omar SZ, Jamalpour S, Tan PC
    J Diabetes Res, 2020;2020:9072492.
    PMID: 32090124 DOI: 10.1155/2020/9072492
    Background: Defects in incretin have been shown to be related to the pathogenesis of type 2 diabetes. Whether such a deficiency happens in gestational diabetes mellitus (GDM) remains to be confirmed. We assessed the association of fasting glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) with GDM. We also studied the longitudinal circulation of these peptides during pregnancy and afterwards.

    Methods: 53 women with GDM (30 managed with diet only (GDM-diet) and 23 treated with insulin (GDM-insulin)) and 43 pregnant women with normal glucose tolerance (NGDM) were studied, with GIP and GLP-1 levels measured at 24-28 weeks (E1), prior (E2) and after (E3) delivery, and postpuerperium (E4).

    Results: Basal GIP was shown to be low in GDM groups compared to NGDM in E1, and in E4 for GDM-diet. GLP-1 was low in GDM groups during pregnancy and afterwards. At E1, serum GIP and GLP-1 were inversely associated with GDM and participants with lower levels of GIP (<0.23 ng/mL) and GLP-1 (<0.38 ng/mL) had a 6 (95% CI 2.5-14.5)- and 7.6 (95% CI 3.0-19.1)-fold higher risk of developing GDM compared with the higher level, respectively. In the postpuerperium, when there is a drop in β-cell function, participants with previous GDM (pGDM) presented lower GLP-1 (in both GDM subgroups) and lower GIP in GDM-diet subgroup compared to controls.

    Conclusion: There is an independent, inverse association between fasting incretins and higher risk of GDM. Furthermore, lowered levels of these peptides may play an important role in the abnormality of glucose regulation following pregnancy.

    PMID: 17000504
    Gemeprost (Cervagem) has been used widely compared with Misoprostol (Cytotec) alone in second trimester pregnancy termination. This prospective randomised trial was to evaluate the efficacy of intravaginal Misoprostol (alone) and Gemeprost in second trimester termination of pregnancy. A total of 54 women with 27 on each arm were involved. A total of 25 patients (92.6%) in the Misoprostol group and 22 patients (81.5%) in the Gemeprost group delivered within 48 h. The Misoprostol group delivered earlier, although average number of tablets required were similar. The side-effects were not significant between the two groups in fact, but there was more pyrexia in the Gemeprost group (p = 0.004). Misoprostol in second trimester termination of pregnancy is clinically as effective and less costly than the standard regimen of Gemeprost.

    Threatened miscarriage is a common complication of pregnancy. Despite initial viability confirmation by ultrasound scan, some of these patients had further spontaneous abortion. A highly sensitive and specific biomarker would be useful to determine the outcome of pregnancy and to prevent emotional impact to these women. A prospective 14-month cohort study was conducted in the Obstetrics and Gynaecology Department of Universiti Kebangsaan Malaysia Medical Centre to determine whether low serum levels of pregnancy-associated plasma protein A (PAPP-A) measured in early pregnancy can predict the outcome of threatened abortion. 42 pregnant women between 6 to 22 weeks of gestation with threatened abortion and 40 controls were enrolled. Serum samples were collected at presentation and PAPP-A was assayed by electrochemiluminescent immunoassay technique. Pregnancies were followed-up until 22 weeks of gestations and the outcome documented. Nine patients (11%) developed spontaneous abortion and 73 patients (89%) had successful pregnancy. The median PAPP-A level was significantly lower in patients with spontaneous abortion compared to those who had successful pregnancies in the threatened abortion group: 0.78 MoM (0.41-1.00 MoM) vs 1.00 MoM (1.00-2.0 MoM) respectively (p < 0.05). The best sensitivity of 44% and specificity of 93% were obtained at the cut of value of 0.66 MoM (95% CI, 0.561-0.773). In conclusion, low PAPP-A value in threatened abortion women is associated with pregnancy failure, although the use of PAPP-A as a one-time single marker has limited value.

    Ong BB, Wong KT
    Malays J Pathol, 1996 Dec;18(2):121-3.
    PMID: 10879233
    A rare case of a 22-week-old foetus with unilateral adrenal cytomegaly and left diaphragmatic hernia is reported. Typical cytomegalic cells were found focally in the left adrenal but the right adrenal was normal. There was no stigmata of the Beckwith-Wiedermann syndrome. The association of adrenal cytomegaly with various congenital malformations, the significance and possible pathogenesis of this condition is discussed.

  8. Maternal adiposity and blood pressure in pregnancy: varying relations by ethnicity and gestational diabetes
    Lim WY, Kwek K, Chong YS, Lee YS, Yap F, Chan YH, et al.
    J Hypertens, 2014 Apr;32(4):857-64.
    PMID: 24390251 DOI: 10.1097/HJH.0000000000000096
    OBJECTIVE: Greater maternal adiposity is a potentially modifiable risk factor for elevated blood pressure during pregnancy; however, the association has been little studied in Asian populations, and no study has evaluated potential differences in the adiposity-blood pressure relation between ethnic groups or interaction with gestational diabetes.

    METHODS: We performed a cross-sectional evaluation of a Singapore mother-offspring cohort comprising 799 pregnant Chinese, Malay and Indian women. Data on body weight, height, skinfold thickness and glycaemia (oral glucose tolerance test) were collected during the 2nd trimester; peripheral SBP and DBP were measured using an oscillometric device and central pressures by noninvasive radial applanation tonometry. The associations between adiposity measures BMI and sum of skinfold thickness and blood pressure outcomes were examined by linear regression with adjustment for potential confounders.

    RESULTS: Higher maternal BMI was associated with elevated peripheral and central pressures: the increases in pressure (mmHg) for each kg/m(2) increase in BMI were 1.19 (95% confidence interval, 1.03-1.36) for peripheral SBP, 0.76 (0.63-0.89) for peripheral DBP, 1.02 (0.87-1.17) for central systolic pressure and 0.26 (0.16-0.37) for central pulse pressure. The associations were generally stronger in Chinese women (P-interaction = 0.03 for central pulse pressure) and individuals with gestational diabetes (P-interaction = 0.03 for DBP and P-interaction = 0.046 for central systolic pressure). Similar patterns of results were found when using skinfold thickness as the measure of adiposity.

    CONCLUSION: Maternal adiposity is associated with higher peripheral and central blood pressures during pregnancy. Stronger associations in Chinese women and individuals with gestational diabetes warrant further investigation.

  9. Highly potent stem cells from full-term amniotic fluid: A realistic perspective
    Hamid AA, Joharry MK, Mun-Fun H, Hamzah SN, Rejali Z, Yazid MN, et al.
    Reprod Biol, 2017 Mar;17(1):9-18.
    PMID: 28262444 DOI: 10.1016/j.repbio.2017.02.001
    Amniotic fluid (AF) is now known to harbor highly potent stem cells, making it an excellent source for cell therapy. However, most of the stem cells isolated are from AF of mid-term pregnancies in which the collection procedure involves an invasive technique termed amniocentesis. This has limited the access in getting the fluid as the technique imposes certain level of risks to the mother as well as to the fetus. Alternatively, getting AF from full-term pregnancies or during deliveries would be a better resolution. Unfortunately, very few studies have isolated stem cells from AF at this stage of gestation, the fluid that is merely discarded. The question remains whether full-term AF harbors stem cells of similar potency as of the stem cells of mid-term AF. Here, we aim to review the prospect of having this type of stem cells by first looking at the origin and contents of AF particularly during different gestation period. We will then discuss the possibility that the AF, at full term, contains a population of highly potent stem cells. These stem cells are distinct from, and probably more potent than the AF mesenchymal stem cells (AF-MSCs) isolated from full-term AF. By comparing the studies on stem cells isolated from mid-term versus full-term AF from various species, we intend to address the prospect of having highly potent amniotic fluid stem cells from AF of full-term pregnancies in human and animals.

    Yong HY, Shariff ZM, Mohd Yusof BN, Rejali Z, Bindels J, Tee YYS, et al.
    Nutr Res Pract, 2019 Jun;13(3):230-239.
    PMID: 31214291 DOI: 10.4162/nrp.2019.13.3.230
    BACKGROUND/OBJECTIVES: Little is known about the dietary patterns (DPs) of women during pregnancy. The present study aimed to identify the DPs of pregnant Malaysian women and their associations with socio-demographic, obstetric, and anthropometric characteristics.
    SUBJECTS AND METHODS: This prospective cohort study included 737 participants enrolled in Seremban Cohort Study between 2013 and 2015. Food consumption was assessed using a validated 126-food item semi-quantitative food frequency questionnaire (SFFQ) at four time-points, namely, pre-pregnancy and at each trimester (first, second, and third). Principal component analysis (PCA) was used to identify DPs.
    RESULTS: Three DPs were identified at each time point and designated DP 1-3 (pre-pregnancy), DP 4-6 (first trimester), DP 7-9 (second trimester) and DP 10-12 (third trimester). DP 1, 4, and 7 appeared to be more prudent diets, characterized by higher intakes of nuts, seeds & legumes, green leafy vegetables, other vegetables, eggs, fruits, and milk & dairy products. DP 2, 5, 8, and 11 had greater loadings of condiments & spices, sugar, spreads & creamer, though DP 2 had additional sweet foods, DP 5 and 8 had additional oils & fats, and DP 11 had additional tea & coffee, respectively. DP 3 and 6 were characterized by high protein (poultry, meat, processed, dairy, eggs, and fish), sugars (mainly as beverages and sweet foods), and energy (bread, cereal & cereal products, rice, noodles & pasta) intakes. DP 9 had additional fruits. However, DP 12 had greater loadings of energy foods (bread, cereal & cereal products, rice, noodles & pasta), sugars (mainly as beverages, and sweet foods), and good protein sources (eggs, nuts, seeds & legumes). Malays were more likely to have lower adherence (LA) for DP 1 and 10 than non-Malays. DP 2, 8, and 11 were more prevalent among Malays than non-Malays. Women with a higher education were more likely to have LA for DP 10, and women with a greater waist circumference at first prenatal visit were more likely to show LA for DP 11.
    CONCLUSIONS: DPs observed in the present study were substantially different from those reported in Western populations. Information concerning associations between ethnicity, waist circumference and education with specific DPs before and throughout pregnancy could facilitate efforts to promote healthy dietary behavior and the overall health and well-being of pregnant women.

  11. Profiles of women presenting for abortions in Singapore: focus on teenage abortions and late abortions
    Lim L, Wong H, Yong E, Singh K
    Eur J Obstet Gynecol Reprod Biol, 2012 Feb;160(2):219-22.
    PMID: 22137571 DOI: 10.1016/j.ejogrb.2011.11.017
    OBJECTIVE: Teenage abortions predispose women to adverse pregnancy outcomes in subsequent pregnancies such as anemia, stillbirths, preterm deliveries and low birth weight babies. We aim to profile the women presenting for abortions in our institution and determine risk factors for late presentation for abortions.
    STUDY DESIGN: In this retrospective cohort study, all women who underwent an abortion at the National University Hospital, Singapore, from 2005 to 2009 were recruited. Data was obtained from a prepared questionnaire during the mandatory pre-abortion counseling sessions. Profiles of women aged <20 years were compared with those ≥ 20 years old using Chi-square test if the assumptions for Chi-square test were met; otherwise, Fisher's exact test was carried out. Logistic regression was used to investigate the risk factors for second trimester termination of pregnancy.
    RESULTS: 2109 women presented for induced abortions, of which 1998 had single abortion throughout the course of the study. The mean age of women with single abortion was 29.1 years (sd 7). In the group of women with single abortion, 182 (9.1%) were teenage abortions. In contrast to women ≥ 20 years of age, pregnant teenagers were more likely not to have used any contraception (51.1% vs. 25.2%) and more likely to present late for abortions (39.6% vs. 15.9%). Other risk factors for late presentation for abortions include Malay ethnicity, singlehood, nulliparity and lack of prior usage of contraception.
    CONCLUSION: Teenagers are more likely to have no prior contraceptive usage and to present late for abortions. Lack of proper sexual education and awareness of contraceptive measures may have a major contributory factor to such a trend in teenage abortions. Recommendations have been made in order to curb this societal problem.

    PMID: 19145718
    OBJECTIVES: Maternal periodontitis has been suggested as one of the risk factors for low birth weight (LBW) infants. The objective of this study was to determine the association between maternal periodontitis and LBW infants among Malay women.

    METHODS: Screening periodontal examinations were carried out on all eligible Malay pregnant women in the second trimester of pregnancy attending two randomly selected community maternal and child health clinics in Kota Bharu, Kelantan. Patients with four or more sites with pocket depth 4 mm or higher, and clinical attachment loss 3 mm or higher at the same site with presence of bleeding on probing were diagnosed as having periodontitis in this study. Using this definition, systematic random sampling was utilized for selection of 250 subjects for each exposed and non-exposed group. Of 500 subjects enrolled in the study, 28 (5.6%) were either dropped or lost to follow-up. Of the remaining 472 subjects, 232 with periodontitis were in the exposed group and 240 with healthy periodontium were in the nonexposed group.

    RESULTS: The incidence of LBW was 14.2% (95% CI: 9.70-18.75) in women with periodontitis, and 3.3% (95% CI: 1.05-5.62) in women without periodontitis. The relative risk of having LBW infants was 4.27 times higher for women with periodontitis compared with those without periodontitis (95% CI: 2.01-9.04). After adjustment for potential confounders using multiple logistic regression analysis, significant association was found between maternal periodontitis and LBW (OR = 3.84; 95% CI: 1.34-11.05).

    CONCLUSION: The results of this study provide additional evidence that pregnant women with periodontitis are at a significantly higher risk of delivering LBW infants.

    PMID: 12069143 DOI: 10.1111/j.0004-8666.2002.00164.x
    OBJECTIVES: The objectives of this study were to investigate the prevalence of factor V Leiden mutation in Malay women with recurrent spontaneous abortion and to clarify the contribution of the factor V Leiden mutation to recurrent miscarriages in these women.

    DESIGN: A prospective case control study between June 1999 and April 2000.

    SETTING: Hospital University Science of Malaysia, Kubang Kerian, Kelantan, and Maternal and Child Health Clinic, Pasir Mas, Kelantan, Malaysia.

    SAMPLES: A total of 46 Malay women with a history of three or more first or second trimester miscarriages were studied. The control group consisted of 46 parous women without obstetric complications.

    METHODS: Diagnosis of factor V Leiden mutation was made by examination of factor V Leiden allele product following Mnl I digestion of factor V Leiden alleles amplified by polymerase chain reaction.

    RESULTS: None of the 46 women with recurrent spontaneous abortion carried the mutation. Also, we found no subject carrying the factor V Leiden alleles in the control group.

    CONCLUSION: These results suggest that that there is no association between the factor V Leiden mutation and recurrent spontaneous abortion in the Malay population.

    PMID: 9325520
    This prospective, randomized study compared the efficacy of intravaginal misoprostol (Cytotec) and gemeprost (Cervagem) as an abortifacient for intrauterine deaths in second trimester pregnancy. Side-effects, complications and the cost-effectiveness associated with each drug were assessed. 21 out of 25 patients (84%) in the misoprostol group aborted whereas only 17 out of 25 patients (68%) in the gemeprost group aborted within 24 hours after the initiation of therapy. In the misoprostol group, the abortion rate was influenced by the gestational age with 100% abortion rate for those > 17 weeks' gestation compared to 67% for those with a gestational age of 13-16 weeks. Side-effects were rare in either group and no major complications were reported in either group. Misoprostol was definitely more cost-effective compared to gemeprost as the mean cost of inducing an abortion using misoprostol was RM 1.08 whereas that of gemeprost was RM 105. We thus concluded that misoprostol was at least as effective as gemeprost as an abortifacient for intrauterine death in second trimester pregnancy. Moreover, it was less costly, with very few side-effects.

  15. Fulltext Associations of gestational cardiovascular health with pregnancy outcomes: the Hyperglycemia and Adverse Pregnancy Outcome study
    Perak AM, Lancki N, Kuang A, Labarthe DR, Allen NB, Shah SH, et al.
    Am J Obstet Gynecol, 2021 02;224(2):210.e1-210.e17.
    PMID: 32768430 DOI: 10.1016/j.ajog.2020.07.053
    BACKGROUND: The American Heart Association's formal characterization of cardiovascular health combines several metrics in a health-oriented, rather than disease-oriented, framework. Although cardiovascular health assessment during pregnancy has been recommended, its significance for pregnancy outcomes is unknown.

    OBJECTIVE: The purpose of this study was to examine the association of gestational cardiovascular health-formally characterized by a combination of 5 metrics-with adverse maternal and newborn outcomes.

    STUDY DESIGN: We analyzed data from the Hyperglycemia and Adverse Pregnancy Outcome study, including 2304 mother-newborn dyads from 6 countries. Maternal cardiovascular health was defined by the combination of the following 5 metrics measured at a mean of 28 (24-32) weeks' gestation: body mass index, blood pressure, lipids, glucose, and smoking. Levels of each metric were categorized using pregnancy guidelines, and the total cardiovascular health was scored (0-10 points, where 10 was the most favorable). Cord blood was collected at delivery, newborn anthropometrics were measured within 72 hours, and medical records were abstracted for obstetrical outcomes. Modified Poisson and multinomial logistic regression were used to test the associations of gestational cardiovascular health with pregnancy outcomes, adjusted for center and maternal and newborn characteristics.

    RESULTS: The average age of women at study exam was 29.6 years old, and they delivered at a mean gestational age of 39.8 weeks. The mean total gestational cardiovascular health score was 8.6 (of 10); 36.3% had all ideal metrics and 7.5% had 2+ poor metrics. In fully adjusted models, each 1 point higher (more favorable) cardiovascular health score was associated with lower risks for preeclampsia (relative risk, 0.67 [95% confidence interval, 0.61-0.73]), unplanned primary cesarean delivery (0.88 [0.82-0.95]), newborn birthweight >90th percentile (0.81 [0.75-0.87]), sum of skinfolds >90th percentile (0.84 [0.77-0.92]), and insulin sensitivity <10th percentile (0.83 [0.77-0.90]). Cardiovascular health categories demonstrated graded associations with outcomes; for example, relative risks (95% confidence intervals) for preeclampsia were 3.13 (1.39-7.06), 5.34 (2.44-11.70), and 9.30 (3.95-21.86) for women with ≥1 intermediate, 1 poor, or ≥2 poor (vs all ideal) metrics, respectively.

    CONCLUSION: More favorable cardiovascular health at 24 to 32 weeks' gestation was associated with lower risks for several adverse pregnancy outcomes in a multinational cohort.
