Background:Gardnerella vaginalis (GV) is most frequently associated with bacterial vaginosis and is the second most common etiology causing intrauterine infection after Ureaplasma urealyticum. Intrauterine GV infection adversely affects pregnancy outcomes, resulting in preterm birth, fetal growth restriction, and neonatal pneumonia. The knowledge of how GV exerts its effects is limited. We developed an in vivo animal model to study its effects on fetal development. Materials and Methods: A survival mini-laparotomy was conducted on New Zealand rabbits on gestational day 21 (28 weeks of human pregnancy). In each dam, fetuses in the right uterine horn received intra-amniotic 0.5 × 102 colony-forming units of GV injections each, while their littermate controls in the left horn received sterile saline injections. A second laparotomy was performed seven days later. Assessment of the fetal pups, histopathology of the placenta and histomorphometric examination of the fetal lung tissues was done. Results: Three dams with a combined total of 12 fetuses were exposed to intra-amniotic GV, and 9 fetuses were unexposed. The weights of fetuses, placenta, and fetal lung were significantly lower in the GV group than the saline-inoculated control group [mean gross weight, GV (19.8 ± 3.8 g) vs. control (27.9 ± 1.7 g), p < 0.001; mean placenta weight, GV (5.5 ± 1.0 g) vs. control (6.5 ± 0.7 g), p = 0.027; mean fetal lung weight, GV (0.59 ± 0.11 g) vs. control (0.91 ± 0.08 g), p = 0.002. There was a two-fold increase in the multinucleated syncytiotrophoblasts in the placenta of the GV group than their littermate controls (82.9 ± 14.9 vs. 41.6 ± 13.4, p < 0.001). The mean alveolar septae of GV fetuses was significantly thicker than the control (14.8 ± 2.8 μm vs. 12.4 ± 3.8 μm, p = 0.007). Correspondingly, the proliferative index in the interalveolar septum was 1.8-fold higher in the GV group than controls (24.9 ± 6.6% vs. 14.2 ± 2.9%, p = 0.011). The number of alveoli and alveolar surface area did not vary between groups. Discussion: Low-dose intra-amniotic GV injection induces fetal growth restriction, increased placental multinucleated syncytiotrophoblasts and fetal lung re-modeling characterized by alveolar septal hypertrophy with cellular proliferative changes. Conclusion: This intra-amniotic model could be utilized in future studies to elucidate the acute and chronic effects of GV intrauterine infections.
OBJECTIVE: This was to determine HOMA-IR score as well as to assess its association in fetal and maternal outcomes among pregnant women with diabetes risks.
METHODS: A prospective cohort study of pregnant women with diabetes risks was done. GDM was diagnosed using modified glucose tolerance test. Serum insulin was taken and measured by an electrochemiluminescence immunoassay method. Plasma glucose was measured by enzymatic reference method with hexokinase. HOMA-IR score was calculated for each patient. Maternal and fetal outcomes were analyzed.
RESULTS: From 279 women recruited, 22.6% had GDM with higher HOMA-IR score (4.07 ± 2.44 versus 2.08 ± 1.12; p = 0.001) and fasting insulin (16.76 ± 8.63 µIU/L versus 10.15 ± 5.07 µIU/L; p = 0.001). Area under ROC curve for HOMA-IR score was 0.79 (95% confidence interval, 0.74-0.84) with optimum cut-off value of 2.92 (sensitivity = 63.5%; specificity = 89.8%), higher than recommended by IDF (2.38). This point showed significant association with neonatal hypoglycemia (p = 0.02) and Cesarean section (p = 0.04) in GDM mothers.
CONCLUSIONS: HOMA-IR score and insulin resistance levels were higher in GDM women in our population. With the cut-off HOMA-IR value of 2.92, neonatal hypoglycemia and Cesarean section were significant complications in GDM mothers. This can be used in anticipation of maternal and fetal morbidities.
Hb Adana [HBA2: c179G>A (or HBA1); p.Gly60Asp] is a rare hemoglobin (Hb) variant due to a mutation at codon 59 of the α2- or α1-globin gene resulting in a glycine to aspartic acid substitution. Two siblings with a unique coinheritance of Hb Adana and Hb Constant Spring (Hb CS, α142, Term→Gln, TAA>CAA; HBA2: c.427 T>C) (α(codon 59)α/α(CS)α), were compared phenotypically with another two siblings carrying the Hb Adana mutation and a 3.7 kb deletion (α(codon 59)α/-α(3.7)). Although they all had α-thalassemia intermedia (α-TI), the former were clinically more severe than the latter. The first pair of siblings presented at a much younger age than the second pair and showed lower Hb levels and significant extramedullay hemopoiesis. Another case of a hydropic fetus as a result of Hb H/Hb Adana is also described. Their clinical phenotypes and hematological parameters are all presented for comparison.
Endometriosis is a disease known to be detrimental to fertility. Women with endometriosis, and the presence of endometrioma, may require artificial reproductive techniques (ART) to achieve a pregnancy. The specific impact of endometrioma alone and the impact of surgical intervention for endometrioma on the reproductive outcome of women undergoing IVF/ICSI are areas that require further clarification. The objectives of this review were as follows: (i) to determine the impact of endometrioma on IVF/ICSI outcomes, (ii) to determine the impact of surgery for endometrioma on IVF/ICSI outcome and (iii) to determine the effect of different surgical techniques on IVF/ICSI outcomes.
An episode of clinically recovered acute kidney injury (r-AKI) has been identified as a risk factor for future hypertension and cardiovascular disease. Our objective was to assess whether r-AKI was associated with future preeclampsia and other adverse pregnancy outcomes and to identify whether severity of AKI or time interval between AKI and pregnancy was associated with pregnancy complications. We conducted a retrospective cohort study of women who delivered infants between 1998 and 2016 at Massachusetts General Hospital. AKI was defined using the 2012 Kidney Disease Improving Global Outcomes laboratory criteria with subsequent clinical recovery (estimate glomerular filtration rate, >90 mL/min per 1.73 m2 before conception). AKI was further classified by severity (Kidney Disease Improving Global Outcomes stages 1-3) and time interval between AKI episode and the start of pregnancy. Women with r-AKI had an increased rate of preeclampsia compared with women without previous r-AKI (22% versus 9%; P<0.001). Infants of women with r-AKI were born earlier (gestational age, 38.2±3.0 versus 39.0±2.2 weeks; P<0.001) and were more likely to be small for gestational age (9% versus 5%; P=0.002). Increasing severity of r-AKI was associated with increased risk of preeclampsia for stages 2 and 3 AKI (adjusted odds ratio, 3.5; 95% confidence interval, 2.1-5.7 and adjusted odds ratio, 6.5; 95% confidence interval, 3.5-12.0, respectively), but not for stage 1 (adjusted odds ratio, 1.7; 95% confidence interval, 0.9-3.2). A history of AKI before pregnancy, despite apparent full recovery, was associated with increased risk of pregnancy complications. Severity and timing of the AKI episode modified the risk.
Background: Oral disease in association of pregnancy outcome has been long researched.
Most pregnant women perceived that oral disease in pregnancy are expected and considered
to be normal. Objective: This study aims to evaluate the knowledge of pregnant women and
their practices towards oral disease. Methods: 296 pregnant mothers were recruited from
government clinics in Kuantan, Malaysia. A validated and self -administered questionnaire
assessing knowledge, attitudes and practices towards oral health was used. Results were
analysed by descriptive analysis, chi square test and multiple logistic regression. Results:
Most respondents showed poor knowledge on oral health problem with its pregnancy
outcome (66.6%) and poor attitude about dental health during pregnancy (53.4%). Half of
them had good practice on oral health. Tooth cavity (46.3%) and gum bleeding (29.4%) were
the commonest problem reported by them. Only one third of the mothers utilize dental
service. Higher level of education was associated with better oral health practice [OR:0.02 CI
(1.12,3.92)] Conclusions: Knowledge on the relationship between oral health and pregnancy
outcome is still low among pregnant mothers. Utilization of dental service was also low. High
level of education is proven to give better oral health care.
Introduction In Malaysia although mortality rate among women of reproductive ages has
reduced over the years, the reduction has been stagnant for the past ten years.
In order to achieve the 5th Millennium Development Goal, several measures
need to be taken including a proper implementation of pre-pregnancy
services in this country. This study explores the awareness, intention and
usage of pre-pregnancy care (PPC) services and its determinant among
women of reproductive ages in Kedah, Malaysia.
Methods This is a qualitative study, which consisted of a focus group discussion
(FGD) among women in the ages of 18 to 45 years old from all ethnic groups
who attended four government clinics in the state of Kedah. The mothers
were chosen through purposive sampling from twelve districts that were
selected through a multistage random sampling. A semi-structured
questionnaire was utilized during the FGD. The results from the FGD were
recorded verbatim and thematic analysis was finalized once saturation of
information from respondents was achieved.
Results These are two themes was identified, namely personal reasons and reasons of
service and there are several subthemes under two main themes. Under the
Personal reason themes, the subthemes including awareness and intention to
used the services, knowledge, perception, social support and history of
medical illness. While under pre-pregnancy care services themes, the
subthemes including the promotion of the services, the communication
relationship with the health staff, the waiting time and also the accessibility
of the service.
Conclusions As a conclusion, there is still part of society who was unaware of prepregnancy
services and its importance in reducing maternal mortality rate as
well as producing good pregnancy outcome. Information and knowledge on
pre-pregnancy care services should be disseminated among community
members through various means including roadshows and pre wedding
workshops.
Objective: The aim of this study is to evaluate the outcome of pregnancy in prenatal and postnatal period of pregnancy complicated with thick nuchal translucency but normal karyotype. Methods: This is a retrospective study of 119 singleton pregnancies with increased NT (NT > 2.5mm) but a normal karyotype over a 3 year period. The records of ultrasound at 18-20 and 25-26 weeks’, antenatal and postnatal details were reviewed. The developmental and health outcomes of the surviving children were obtained through telephone conversation with the family. Adverse outcome such as miscarriages, termination of pregnancy, intrauterine death, structural anomalies and neurodevelopment delay were analysed. Results: Out of 119 foetuses with increased NT but normal karyotype, 11.8% of pregnancies ended with miscarriages, termination of pregnancy and intrauterine death. 89.9% foetuses were structurally normal. 12.9% presented with structural anomalies in the second-trimester ultrasound scan. 81.8% showed major malformations, out of which 44% consisted of heart defects. 1% of foetuses were syndromic and 1.9% had developmental delay. 96.8% of foetuses with NT equal to or greater than the 95th percentile (3.4mm) and 80% with NT equal to or greater than the 99 percentile (5.5mm) had a normal outcome. 50% of foetuses with thickened nuchal fold had a poor outcome. Postnatal follow-up was established for all infants and toddlers, and abnormalities were observed in 5.6% of them. Chances of having a live and healthy infant decreases with increased NT, corresponding to 80% for NT equal to or greater than 5.5mm. Conclusion: We have provided data that may help in the counselling of parents and increasing their confidence on a favourable pregnancy outcome. In cases with increased nuchal translucency but normal karyotype, the chances of normal pregnancy success rate is 89.9%. Parents can be reassured that thickened nuchal translucency with a normal karyotype and normal targeted ultrasound between 20-22 weeks gestation, the risk of adverse perinatal outcome and postnatal developmental delay is not increased in comparison with that of the general population. This seems to be the case for all degrees of increased nuchal translucency.
Introduction: To review the gestational age at diagnosis, method of diagnosis, pregnancy outcome and
maternal complications of prenatally diagnosed lethal foetal anomalies. Methods: Retrospective review of 25
women who had aborted or delivered foetuses with lethal anomalies in a tertiary hospital in 2011 based on
patient medical records. Results: There were a total of 10,088 deliveries, in which 25 (0.24%) women were
found to have conceived foetuses with lethal anomalies. All of them were diagnosed by prenatal ultrasound
and only 7 (28.0%) had both prenatal ultrasound and genetic study done. The women’s mean age was 29.9
years old. The mean gestational age at diagnosis of lethal foetal anomalies was 25.5 weeks (SD=12.5) and
mean gestational age at termination of pregnancy (TOP) or delivery was 28.5 weeks (SD=12.5). Seven (28%)
women had early counseling and TOP at the gestation of < 22 weeks. Beyond 22 weeks of gestation, eight
(32%) women had TOP and ten (40%) women had spontaneous delivery. Twenty (80%) women delivered or
aborted vaginally, three (12%) women with assisted breech delivery and two (8%) women with abdominal
delivery which were performed due to transverse foetal lie in labour and a failed induction, leading to
emergency hysterotomy complicated by hysterectomy due to intraoperative finding of ruptured uterus.
Overall, the associated post-partum adverse events included post-partum haemorrhage (12%), retained
placenta (12%), blood transfusion (8%), uterine rupture (4%) and endometritis (4%). Mean duration of hospital
stay was 6.6 days (SD 3.7 days). Conclusion: Late diagnosis of lethal foetal anomalies leads to various
maternal morbidities, in this case series , which could have been prevented if they were diagnosed and
terminated at early trimester. A new direction is needed in our local practice.
Monoamniotic twin pregnancy is a rare type of twin pregnancy which poses risk of cord entanglement and
sudden death of either one or both fetuses. The role of antenatal surveillance by Ultrasound Doppler for
umbilical cord and ultrasonic evidence of cord entanglement or knotting may predict the pregnancy outcome
but yet unavoidable. The discussion will include antenatal surveillance in this rare type of pregnancy.
Objective: To assess the adequacy of antenatal care (ANC) and its association with pregnancy outcomes using an approach that includes adequacy of both utilization and content.
Design: Retrospective cohort study.
Setting and Participants: Women attending ANC at public-funded primary health clinics where data were extracted from individual records.
Methods: Adequacy of utilization assessment was based on the concept of Adequacy of Prenatal Care Utilization index; adequacy of content assessed the recommended routine care received by the women according to local guidelines. Association between adequacy and pregnancy outcomes was examined using binary logistic regression.
Main Outcome Measures: Pregnancy outcomes included preterm birth and low birth weight.
Results: Sixty-three percent of women showed higher than recommended ANC utilization; 52% had <80% of recommended routine care content. Although not statistically significant, the odds of preterm birth was lower among women with adequate level of utilization compared with inadequate (adjusted odds ratios (aOR) = 2.34, 95% confidence interval (CI) 0.45-12.16) and intensive levels (aOR = 3.27, 95% CI 0.73-14.60). Regarding adequacy of content, women who received inadequate level of care content were associated with higher prevalence of preterm birth (aOR = 3.69, 95% CI 1.60-8.55).
Conclusion: The study shows inadequate content is associated with higher prevalence of preterm birth and suggests that inadequate utilization increases the risk of preterm birth. It demonstrates the relevance of using both utilization and content assessment in evaluating quality of ANC. Further studies are encouraged to review the methods used.
The treatment of heart failure in pregnant women is more difficult than in non-pregnant women, and should always involve a multidisciplinary team approach. Knowledge required includes hemodynamic changes in pregnancy and the resultant effect on women with pre-existing or pregnancy-related cardiovascular disease, cardiovascular drugs in pregnancy, ethical issues and challenges regarding saving mother and baby. In addition, women having high risk cardiac lesions should be counselled strongly against pregnancy and followed up regularly. Pregnancy with heart failure is an important issue, demanding more comprehensive studies.
Peripartum cardiomyopathy (PPCM) is an uncommon form of congestive heart failure, afflicting obstetric patients around the time of delivery. The epidemiology of PPCM is infrequently reported. To the best of our knowledge, there has been no report from Asia.
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.
Information on the role of 25-hydroxyvitamin D (25(OH)D) in preventing adverse pregnancy/neonatal outcomes is limited in Malaysia. This study aims to determine the relationship between the level of maternal 25(OH)D in the first trimester of pregnant women and their pregnancy/neonatal outcomes. A total of 60 pregnant women in the first trimester were recruited and followed until the end of their pregnancy. The occurrence of any antenatal, delivery, and neonatal complications was recorded. Their blood was collected in the first trimester for total serum 25(OH)D determination using enzyme-linked immunosorbent assay. Overall, 10% of the women had vitamin D deficiency, while 57% had vitamin D insufficiency in their first trimester. No statistically significant difference in 25(OH)D level/status was observed between women with or without antenatal and delivery complications (p > 0.05). No difference in maternal serum 25(OH)D level and vitamin D status was observed between neonates with or without complications (p > 0.05). In conclusion, there is a high prevalence of vitamin D insufficiency among Malaysian pregnant women, but it is not associated with adverse maternal and neonatal outcomes. More comprehensive studies should be planned to verify this relationship.
The association between maternal COVID-19 infection, placental histomorphology and perinatal outcomes is uncertain. The published studies on how placental structure is affected after SARS-CoV-2 virus in COVID-19-infected pregnant women are lacking. We investigated the effects of maternal SARS-CoV-2 infection on placental histomorphology and pregnancy outcomes. A retrospective cohort study on 47 pregnant women with confirmed SARS-CoV-2 infection, matched with non-infected controls, was conducted. Relevant clinicopathological data and primary birth outcomes were recorded. Histomorphology and SARS-CoV-2 immunohistochemistry analyses of placental tissues were performed. Only 1 of 47 cases showed SARS-CoV-2 immunoreactivity in the syncytiotrophoblasts. Histologically, decidual vasculopathy (n = 22/47, p = 0.004), maternal vascular thrombosis (n = 9/47, p = 0.015) and chronic histiocytic intervillositis (n = 10/47, p = 0.027) were significantly higher in the COVID-19-infected placentas when compared to the control group. Maternal vascular thrombosis was a significant feature in the active COVID-19 group. A significant lower gestational age (p < 0.001)) at delivery and a higher caesarean section rate (p = 0.007) were observed in the active SARS-CoV-2-infected cases, resulting in a significant lower fetal-placental weight ratio (p = 0.022) and poorer Apgar score (p < 0.001). Notably, active (p = 0.027), symptomatic (p = 0.039), severe-critical (p = 0.002) maternal COVID-19 infection and placental inflammation (p = 0.011) were associated with an increased risk of preterm delivery. Altered placental villous maturation and severe-critical maternal COVID-19 infection were associated with an elevated risk of poor Apgar scores at birth (p = 0.018) and maternal mortality (p = 0.023), respectively.
This review aims to evaluate the effectiveness of low glycemic index (GI) dietary intervention for the treatment of gestational diabetes mellitus (GDM), specifically from the Asian perspective. A systematic review of the literature using multiple databases without time restriction was conducted. Three studies were retrieved based upon a priori inclusion criteria. While there was a trend towards improvement, no significant differences were observed in overall glycemic control and pregnancy outcomes in GDM women. However, a tendency for lower birth weight and birth centile if the intervention began earlier was noted. Low GI diets were well accepted and had identical macro-micronutrient compositions as the control diets. However, due to genetic, environment and especially food pattern discrepancies between Western countries and Asians, these results may not be contributed to Asian context. Clearly, there are limited studies focusing on the effect of low GI dietary intervention in women with GDM, particularly in Asia.
OBJECTIVE: To assess the outcomes and risk factors of adolescent pregnancies in 2 major hospitals in Malaysia.
METHODS: We conducted a case-control study of pregnant girls aged 10 through 19 years. The controls were women aged 20 through 35 years who did not become pregnant in their adolescence. Cases and controls were matched for parity and place of delivery. Data were collected from questionnaires and the hospitals' medical records.
RESULTS: The study included 102 cases and 102 controls. There were significant associations between adolescent pregnancy and low education level, low socioeconomic status, being raised by a single parent, not engaging in extracurricular school activities, engaging in unsupervised activities with peers after school, and substance abuse (P<0.05 for all); being anemic, being unsure of the expected delivery date, and having few antenatal visits and a late delivery booking; and low Apgar scores and perinatal complications.
CONCLUSION: Adolescent pregnancies are high-risk pregnancies. Better sexual health strategies are required to address the associated complications.
OBJECTIVE:
To evaluate the 50-g glucose challenge test (GCT) on pregnancy outcome in a multiethnic Asian population at high risk for gestational diabetes (GDM).
METHODS:
GCT was positive if the 1-hour plasma glucose level was >or=7.2 mmol/L. GDM was diagnosed by a 75-g glucose tolerance test using WHO (1999) criteria. Of the 1368 women enrolled in the study, 892 were GCT negative, 308 were GCT false-positive, and 168 had GDM. Pregnancy outcomes were extracted from hospital records. Multivariable logistic regression analysis was performed with GCT negative women as the reference group.
RESULTS:
GCT false-positive status was associated with preterm birth (adjusted odds ratio [AOR] 2.1; 95% CI, 1.2-3.7) and postpartum hemorrhage (AOR 1.7; 95% CI, 1.0-2.7). GDM was associated with labor induction (AOR 5.0; 95% CI, 3.3-7.5), cesarean delivery (AOR 2.2; 95% CI, 1.6-3.2), postpartum hemorrhage (AOR 2.1; 95% CI, 1.2-3.7), and neonatal macrosomia (AOR 2.5; 95% CI, 1.0-6.0).
CONCLUSION:
GCT false-positive women had an increased likelihood of an adverse pregnancy outcome. The role and threshold of the GCT needs re-evaluation.
