Tranexamic acid, as an adjunct to oxytocin prophylaxis, in the prevention of postpartum haemorrhage in women undergoing elective caesarean section: A single-centre double-blind randomised controlled trial.

OBJECTIVE: To evaluate the effectiveness of tranexamic acid (TXA) in reducing blood loss during elective caesarean sections in women with and without risk factors for postpartum haemorrhage (PPH). DESIGN: A double-blind, randomised placebo-controlled trial. SETTING: An academic tertiary referral centre in Singapore. POPULATION: Multiethnic women aged 21 years or older undergoing elective caesarean section. METHODS: Randomisation to intravenous TXA or normal saline (placebo) 10 minutes before skin incision. MAIN OUTCOME MEASURES: Calculated estimated blood loss (cEBL), derived from blood volume and haematocrit levels. RESULTS: Between June 2020 and October 2021, 200 women were randomised to the placebo or TXA groups. Women who received prophylactic TXA had a significantly lower mean cEBL compared with those receiving placebo (adjusted mean difference -126.4 mL, 95% CI -243.7 to -9.1, p = 0.035). The effect was greatest in those at high risk for PPH, with a reduction in cEBL (mean difference -279.6 mL, 95% CI -454.8 to -104.3, p = 0.002) and a lower risk of cEBL ≥500 mL (risk ratio [RR] 0.54, 95% CI 0.36-0.83, p = 0.007) and cEBL ≥1000 mL (RR 0.44, 95% CI 0.20-0.98, p = 0.016). Subgroup analysis showed benefit for women with preoperative haemoglobin <10.5 g/dL (mean difference -281.9 mL, 95% CI -515.0 to -48.8, p = 0.019). There was no significant difference in need for additional medical or surgical interventions. There were no maternal or neonatal adverse outcomes. CONCLUSION: Prophylactic TXA should be considered in women with risk factors for PPH, and those most likely to benefit are those with preoperative haemoglobin <10.5 g/dL.

Dinoprostone vaginal insert (DVI) versus adjunctive sweeping of membranes and DVI for term induction of labor.

AIM: To compare the efficacy and safety of dinoprostone vaginal insert (DVI) alone versus DVI with adjunctive sweeping of membranes (ASM) for induction of labor (IOL). METHODS: Single-center, prospective, randomized controlled trial; women with singleton term pregnancies, cervical dilation ≥1 and <3 cm, intact membranes allocated to either DVI or DVI with ASM. The primary outcome was vaginal delivery within 24 h of insertion. Secondary outcomes included mean time from insertion to delivery, tachysystole, operative delivery for non-reassuring fetal status (NRFS), tocolytics, fetal outcomes, pain information, and subject satisfaction. RESULTS: One hundred and four received DVI (Group 1) alone and 104 DVI with ASM (Group 2). The rate of vaginal delivery within 24 h was 53% versus 56%, cesarean rate 8.7% versus 10.6% in Groups 1 and 2 respectively. Although the duration of labor was similar in both groups, about 6% of women required additional ripening with dinoprostone vaginal tablets in Group 2 compared to 11.5% in Group 1 (p-value = 0.2). The frequency of hyperstimulation syndrome, failed induction, analgesic requirements, and fetal outcomes were comparable. The majority (83%-86%) in either cohort were satisfied with their labor experience. Multivariate logistic regression demonstrated a slightly better chance for vaginal delivery within 24 h (odds ratio [OR] 1.22 [95% confidence interval, CI 0.65-2.29]; p-value 0.53] for DVI with ASM, although statistically insignificant. Younger maternal age and multiparity (OR 10.36 [95% CI 4.88-23.67]; p-value <0.0001) contributed to successful IOL. CONCLUSION: DVI with ASM is at least as efficacious as DVI for cervical ripening with no increase in morbidity. Although DVI with ASM group less often needed additional dinoprostone tablets to complete the process of IOL (p-value = 0.2), adjunctive sweeping has not been shown to have a significant impact on the duration of labor or mode of delivery.

miRNA Regulatory Functions in Farm Animal Diseases, and Biomarker Potentials for Effective Therapies.

MicroRNAs (miRNAs) are small endogenous RNAs that regulate gene expression post-transcriptionally by targeting either the 3' untranslated or coding regions of genes. They have been reported to play key roles in a wide range of biological processes. The recent remarkable developments of transcriptomics technologies, especially next-generation sequencing technologies and advanced bioinformatics tools, allow more in-depth exploration of messenger RNAs (mRNAs) and non-coding RNAs (ncRNAs), including miRNAs. These technologies have offered great opportunities for a deeper exploration of miRNA involvement in farm animal diseases, as well as livestock productivity and welfare. In this review, we provide an overview of the current knowledge of miRNA roles in major farm animal diseases with a particular focus on diseases of economic importance. In addition, we discuss the steps and future perspectives of using miRNAs as biomarkers and molecular therapy for livestock disease management as well as the challenges and opportunities for understanding the regulatory mechanisms of miRNAs related to disease pathogenesis.

Use of Bakri balloon tamponade (BBT) for conservative management of postpartum haemorrhage: a tertiary referral centre case series.

The aim of this study was to investigate the efficacy of the Bakri balloon in the management of PPH. This was a retrospective review of 49 patients, who had Bakri balloon inserted for PPH in KK Hospital between April 2013 and December 2015. The main outcome measure was achievement of haemostasis by Bakri balloon tamponade (BBT). Our success rate was 81.6%. Out of the nine failures (18.0%), five (55.6%) had subtotal hysterectomies and four (44.4%) had total hysterectomies. The causes of PPH in these nine women were unsuspected or foci of placenta accreta (55.6%), uterine atony (33.3%) and retained products of conception (11.1%). Our study suggests that BBT is more likely to fail when bleeding is secondary to undiagnosed focal placenta accreta (p = .011) and when the estimated blood loss is more than 1.5 litres (p < .001). Our study adds to the growing body of evidence that BBT is not only effective for management of PPH in haemodynamically stable patients and in cases secondary to uterine atony and placenta praevia, but also in a small number of undiagnosed focal placenta accreta. Impact statement There is limited evidence regarding efficacy of BBT for PPH. Our study supports the use of BBT for PPH due to uterine atony and placenta praevia and in a small number of undiagnosed placenta accreta.

Coagulase gene polymorphism, enterotoxigenecity, biofilm production, and antibiotic resistance in Staphylococcus aureus isolated from bovine raw milk in North West India.

BACKGROUND: Staphylococcus aureus is the predominant bacterium responsible for various diseases in animals and humans. Preventive strategies could be better implemented by understanding the prevalence, genetic patterns, and the presence of enterotoxin and biofilm-producing genes along with the antibiotic susceptibility of this organism. This study was conducted in Rajasthan, the northwestern state of India, holding the largest population of cattle that makes it the second largest milk producer in India and no such prior information is available on these aspects. METHODS: A total of 368 individual quarter bovine raw milk samples were collected from 13 districts of Rajasthan, and screened for the presence of S. aureus. Microbiological and molecular approaches were followed for bacterial identification. Genetic diversity was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) of coagulase gene (coa), whereas enterotoxin and biofilm-producing genes were studied by PCR analysis. Antibiotic strips were employed to study the antibiotic resistance among strains. RESULTS: In all, 73 S. aureus strains were obtained from 368 bovine raw milk samples out of that only 30 showed the presence of coa. Nine types of coa patterns ranging from 730 to 1130 bp were observed among these isolates. PCR-RFLP of coa distinguished the isolates into 15 genotypic patterns, of which patterns I, IV, V, and VI were predominant. Of the isolates, 30% were positive for sec, 10% for sea, and 3.3% for seb; these genes are responsible for enterotoxin production, whereas all isolates were found positive for icaAD and eno. The prevalence rates of other biofilm-producing genes fnbA, clfB, ebpS, sasG, fnbB, sasC, cna, bap, fib and, bbp were 97, 93, 90, 80, 80, 77, 53, 27, 10, and 6.6%, respectively. Twenty-seven (90%) strains were multidrug resistant, of which 15 were methicillin resistant. Maximum sensitivity was reported for kanamycin and it could be considered as a drug of choice for controlling S. aureus mediated cattle infections in the studied regions. CONCLUSIONS: Overall, these strains could cause several diseases to humans, insisting the need for developing a stricter hygiene program for improving milking practices and animal health.

Prevalence, Virulence Potential, and Antibiotic Susceptibility Profile of Listeria monocytogenes Isolated From Bovine Raw Milk Samples Obtained From Rajasthan, India.

Listeriosis is a serious foodborne disease of a global concern, and can effectively be controlled by a continuous surveillance of the virulent and multidrug-resistant strains of Listeria monocytogenes. This study was planned to investigate prevalence of L. monocytogenes in bovine raw milk samples. A total of 457 raw milk samples collected from 15 major cities in Rajasthan, India, were analyzed for the presence of L. monocytogenes by using standard microbiological and molecular methods. Five of the 457 samples screen tested positive for L. monocytogenes. Multiplex serotyping showed that 3/5 strains belonged to serotype 4b followed by one strain each to 1/2a and to 1/2c. Further virulence potential assessment indicated that all strains possessed inlA and inlC internalins, and, in addition, two strains also possessed the gene for inlB. All strains were positive for Listeriolysin O (LLO) and showed phosphatidylinositol-specific phospholipase C (PI-PLC) activity on an in vitro agar medium with variations in production levels among the strains. A good correlation between the in vitro pathogenicity test and the chick embryo test was observed, as the strains showing higher LLO and PI-PLC activity were found to be lethal to fertilized chick embryos. All strains were resistant to the majority of antibiotics and were designated as multidrug-resistant strains. However, these strains were susceptible to 9 of the 22 tested antibiotics. The maximum zone of inhibition (mm) and acceptable minimum inhibitory concentration were observed with azithromycin, and thus it could be the first choice of a treatment. Overall, the presence of multidrug-resistant L. monocytogenes strains in the raw milk of Rajasthan region is an indicator of public health hazard and highlighting the need of consumer awareness in place and implementation of stricter food safety regulations at all levels of milk production.

Impact of 'fire drill' training and dedicated obstetric resuscitation code in improving fetomaternal outcome following cardiac arrest in a tertiary referral hospital setting in Singapore.

Cardiac arrest in pregnancy is a rare but catastrophic obstetric emergency, with a quoted incidence of 1:20,000 pregnancies. Speedy multidisciplinary interventions are crucial for good maternal and foetal outcomes. A perimortem caesarean section (PMCS) initiated within 4 min of onset of cardiac arrest to minimise the effect of aortocaval compression on cardiopulmonary resuscitation (CPR) has been recommended as a key intervention, which is likely to improve survival of both mother and foetus. Sudden collapse is uncommon in pregnant women and their management is more challenging than in a non-pregnant patient. This article aims to emphasise the significance of early identification and management of impending or established maternal cardiac arrest. We propose that a focus on effective and good-quality CPR, utilising key interventions such as early airway control, left uterine displacement and a timely decision for a PMCS with multidisciplinary input is more likely to result in good maternal and foetal survival and neurological outcomes. We also discuss the role of 'fire drill' obstetric training for key staff and the use of a dedicated hospital-wide resuscitation code for managing collapse in obstetric patients in improving survival and outcomes. We present four cases of maternal cardiac arrest managed with PMCS in our hospital, highlighting the evolution in management and with improved outcomes following changes to our resuscitation guidelines, training and workflows.

Multidisciplinary Obstetric Simulation Training: Experience at KK Women's and Children's Hospital (KKH), Singapore, a Tertiary Referral Centre.

Background Multidisciplinary simulation training in the management of acute obstetric emergencies has the potential to reduce both maternal and perinatal morbidity. It is a valuable tool that can be adapted for targeted audiences of different specialities at all experience levels from medical students to senior consultants. Methods In this study, pre- and post-course questionnaires of learners with varying levels of clinical experience from Obstetrics and Gynaecology (O&G), Anaesthesia, Neonatology, Emergency Medicine, midwifery, and nursing who undertook two simulation courses (namely the Combined Obstetrics Resuscitation Training course, CORE, and the CORE Lite), which comprised lectures and simulation drills with manikins and standardized patients, between 2015 and 2023 were compared. This also included a period when training was affected by the coronavirus disease 2019 (COVID-19) pandemic.  Results The results showed that both simulation courses increased confidence levels among all learners in the management of obstetric emergencies.  Pre-course, participants were most confident in the management of neonatal resuscitation and severe pre-eclampsia, followed by postpartum haemorrhage. They were least confident in the management of vaginal breech delivery, uterine inversion, and twin delivery. Post-course, participants were most confident in the management of neonatal resuscitation and shoulder dystocia, followed by postpartum haemorrhage. They were least confident in the management of uterine inversion and maternal sepsis, followed by vaginal breech delivery and twin delivery. Whilst we saw a huge improvement in confidence levels for all obstetric emergencies, the greatest improvement in confidence levels was noted in vaginal breech delivery, twin delivery, and uterine inversion. Conclusion The simulation courses were effective in improving the confidence in the management of obstetric emergencies. While it may be difficult to measure the improvement in clinical outcomes as a result of simulation courses alone, the increase in confidence levels of clinicians can be used as a surrogate in measuring their preparedness in facing these emergency scenarios.

Comparison of awareness, attitudes and knowledge on human papilloma virus vaccination in Singapore: 2019 versus 2013.

Introduction: This study aimed to assess the changes in the awareness, attitudes and knowledge regarding human papillomavirus (HPV) vaccination among the local population. The secondary aims were to identify barriers and to evaluate the effectiveness of national HPV vaccination campaigns over a six-year period in Singapore. Methods: We conducted and compared two cross-sectional surveys in 2013 and 2019 among female participants attending a general gynaecology clinic. Results: A total of 597 participants completed the survey in 2013 and 2019. The participants were comparable in their race, marital status, educational level, occupation and monthly household income. Knowledge scores for cervical cancer and HPV infection showed significant improvement from 2013 to 2019. There was no significant difference in knowledge scores for HPV vaccination, which resulted in similar uptake of the HPV vaccine. Age, educational level and knowledge of HPV vaccine were significant predictors of acceptance of the HPV vaccine. The top two reasons for declining the HPV vaccine were the lack of knowledge and cost, as noted in the 2019 survey. Conclusion: The Singapore government's efforts to improve cervical cancer awareness through national campaigns and policy changes have led to an improvement in knowledge of HPV infection. However, this has not translated into improvements in the vaccine acceptance rates. The decision for vaccine uptake is complex, and there are multiple factors to be addressed to ensure cost-effective implementation of the strategies. Our study highlights the need for effective dissemination of vaccine information, additional subsidies and consideration of a mandatory school-based vaccination programme.

Medical Management of Atypical Endometrial Hyperplasia: Oncological and Reproductive Outcomes at a Tertiary Center in Singapore.

Background Medical management of atypical endometrial hyperplasia (AEH) includes oral or intrauterine progestins. This study aims to evaluate the oncological and reproductive outcomes of these patients and the predictive factors for disease regression, as well as to compare the treatment efficacy of different forms of progestins. Methodology This retrospective study was conducted at KK Women's and Children's Hospital, Singapore. Women diagnosed with AEH on endometrial biopsy between January 2015 to October 2017 and treated with at least eight weeks of the same progestin were included for analysis. Results Of the 42 patients who met the inclusion criteria, 37 were treated with oral progestins and five with the levonorgestrel intrauterine device (LNG-IUS). In total, 28 (66.6%) patients achieved complete regression (CR), but eight recurred with AEH or endometrial carcinoma. Four (9.5%) progressed to grade 1 endometrioid adenocarcinoma. Patients under 39 years old were 9.75 times more likely (95% confidence interval (CI) = 1.12-85.16, p = 0.04) to achieve CR compared to those who were 40 years old and above. In multivariate analysis, older age and higher mean body mass index had a significantly lower chance of CR. The probability of CR plateaued at nine months at 0.63 (95% CI = 0.47-0.79). There was no significant difference in time to regression, chance of regression, and risk of recurrence between oral progestin and LNG-IUS. Nine patients were trying to conceive. The clinical pregnancy rate was 44.4% (n = 4), and the live birth rate was 22.2% (n = 2). Conclusions Younger patients, especially those below 39 years old, are more likely to achieve CR. The value of medical treatment beyond nine months needs to be re-evaluated. There was no difference in treatment outcomes between oral progestins and LNG-IUS.

Perceptions and acceptance of COVID-19 vaccine among pregnant and lactating women in Singapore: A pre-vaccine rollout cross-sectional study.

Introduction: Vaccination is critical in controlling the coronavirus disease 2019 (COVID-19) pandemic. However, vaccine perception and acceptance among pregnant and lactating women is unknown in Singapore. We aimed to determine the acceptance of COVID-19 vaccination among these two groups of women in Singapore and the factors associated with vaccine acceptance. Methods: We conducted an anonymous, online survey on the perceptions of the COVID-19 vaccine and its acceptance by pregnant and lactating women at a tertiary maternal and child hospital in Singapore from 1 March to 31 May 2021. Information on their demographics and knowledge was collected. These factors were assessed for their relationship with vaccine acceptance. Results: A total of 201 pregnant and 207 lactating women participated. Vaccine acceptance rates in pregnant and lactating women were 30.3% and 16.9%, respectively. Pregnant women who were unsure or unwilling to take the vaccine cited concerns about safety of the vaccine during pregnancy (92.9%), while lactating women were concerned about its potential long-term negative effects on the breastfeeding child (75.6%). Factors that were positively associated with vaccine acceptance included a lower monthly household income or education level, appropriate knowledge regarding vaccine mechanism and higher perceived maternal risk of COVID-19. Most pregnant (70.0%) and lactating women (83.7%) were willing to take the vaccine only when more safety data during pregnancy and breastfeeding were available. Conclusion: COVID-19 vaccine acceptance was low among pregnant and lactating women in Singapore. Addressing the safety concerns when more data are available and education on the mechanism of vaccine action will likely improve acceptance among these women.

Knowledge and Expectations of Perinatal Care Among Pregnant Women During the COVID-19 Pandemic.

Introduction: This study aimed to investigate the knowledge and expectations of pregnant women on perinatal care during the coronavirus disease 2019 (COVID-19) pandemic. Methods: A cross-sectional survey was conducted among pregnant women ≥21 years, without a history of confirmed COVID-19, attending antenatal clinics between August and September 2020 via a secure online platform. The survey consisted of 10 questions which evaluated the knowledge and expectations on perinatal and neonatal care during the current pandemic. Results: A total of 313 pregnant women completed the survey. The mean age of the participants was 30 years (SD 4; range 22-43 years). The median gestational age was 25 weeks (range 4-40 weeks). The participants were predominantly multiparous (54%) and almost all (98%) had completed secondary level education. Majority of participants were aware of the spread of COVID-19 by respiratory secretions and contact (90%), and the importance of prevention strategies (94%). Up to 72% agreed or strongly agreed that in-utero transmission of SARS-CoV-2 was possible. Most were unsure of the optimal mode of delivery (77%) and only 22% believed that breastfeeding was safe in a pregnant woman with active COVID-19. Although 46% were concerned about increased transmission risk with antenatal clinic visits, only 37% were agreeable to teleconferencing of clinic appointments. Maternal age >35 years was significantly associated with agreement with separation of mother-infant after birth [AOR 1.89 (95% CI 1.05, 3.39)], restrictions of visitors during the postnatal period [1.92 (1.05, 3.49)] and having their confinement practices were affected [2.3 (1.26, 4.17)]. Pregnant women who were multiparous disagreed that breastfeeding was safe in women with active COVID-19 [0.42 (0.23, 0.75)]. Conclusions: There was significant uncertainty about the optimal delivery method and safety of breastfeeding with COVID-19 among expectant mothers, along with variable agreement with alterations to routine perinatal care.

Rare case of obstetric cholestasis presenting in the first trimester following in vitro fertilisation.

Intrahepatic cholestasis of pregnancy (ICP) generally presents in the third trimester with pruritus without a rash, characterised by elevated bile acids, with or without transaminitis and hyperbilirubinaemia. Risk factors include a family history of cholestasis, South Asian ethnicity, multifetal gestation, in vitro fertilisation (IVF) and history of hepatitis or biliary disorders.IVF involves the use of high dose gonadotropin stimulation and human chorionic gonadotropin trigger. High doses of progesterone supplementation are additionally given after embryo transfer. The increase in oestrogen and progesterone levels early on in the pregnancy is a possible explanation for the development of ICP in IVF pregnancies at earlier gestations.We present a rare case of iatrogenic ICP presenting in the first trimester in a pregnancy conceived by IVF. Unlike other cases reported, our patient did not have recurrence of ICP in the third trimester, and also had no history of ICP in her first pregnancy.

Management of HIV-positive pregnant women: a Singapore experience.

INTRODUCTION: Perinatal transmission remains one of the important causes of transmission of the human immunodeficiency virus (HIV). Over the years, with better knowledge and awareness of HIV infection, the perinatal transmission rate has been significantly reduced. We previously reported on the pregnancy outcomes of HIV-positive mothers from 1997 to 2007 in our institution. This article aimed to review the standards of care of HIV-positive pregnant women since then. METHODS: A retrospective study reviewed 84 HIV-positive women who delivered in a tertiary centre from January 2008 to December 2015. Patient demographics and antenatal, intrapartum, postnatal and immediate neonatal data were analysed. RESULTS: A total of 97 deliveries with 98 neonates were recorded; 12 women delivered more than once, and there was one set of twins. The mean maternal age at diagnosis of HIV infection was 27.8 years. Of the study population, 63.1% of women were non-Singaporeans. 56 women were known to have HIV infection on presentation and 90.7% were on antiretroviral therapy during pregnancy. 88.7% of the women received intrapartum intravenous zidovudine, and 93.1% of women with detectable and 58.7% with undetectable viral load underwent Caesarean sections. All neonates were HIV-negative. CONCLUSION: The high standards of care for HIV-positive women have successfully reduced our perinatal transmission rate to zero.

A comparison of antenatal prediction models for vaginal birth after caesarean section.

INTRODUCTION: An antenatal scoring system for vaginal birth after caesarean section (VBAC) categorises patients into a low or high probability of successful vaginal delivery. It enables counselling and preparation before labour starts. The current study aims to evaluate the role of Grobman nomogram and the Kalok scoring system in predicting VBAC success in Singapore. METHODS: This is a retrospective study on patients of gestational age 37 weeks 0 day to 41 weeks 0 day who underwent a trial of labour after 1 caesarean section between September 2016 and September 2017 was conducted. Two scoring systems were used to predict VBAC success, a nomogram by Grobman et al. in 2007 and an additive model by Kalok et al. in 2017. RESULTS: A total of 190 patients underwent a trial of labour after caesarean section, of which 103 (54.2%) were successful. The Kalok scoring system (area under curve [AUC] 0.740) was a better predictive model than Grobman nomogram (AUC 0.664). Patient's age (odds ratio [OR] 0.915, 95% CI [confidence interval] 0.844-0.992), body mass index at booking (OR 0.902, 95% CI 0.845-0.962), and history of successful VBAC (OR 4.755, 95% CI 1.248-18.120) were important factors in predicting VBAC. CONCLUSION: Neither scoring system was perfect in predicting VBAC among local women. Further customisation of the scoring system to replace ethnicity with the 4 races of Singapore can be made to improve its sensitivity. The factors identified in this study serve as a foundation for developing a population-specific antenatal scoring system for Singapore women who wish to have a trial of VBAC.

Non-atypical endometrial hyperplasia: risk factors for occult endometrial atypia and malignancy in patients managed with hysterectomy.

OBJECTIVE: To determine the risk factors for occult endometrial atypia and malignancy in patients diagnosed with non-atypical endometrial hyperplasia (NEH) on endometrial biopsy. METHODS: All new cases of NEH diagnosed between April 2015 and March 2016 at KK Women's and Children's Hospital, who underwent hysterectomy as first-line treatment, were included in the study. Patients with a history of endometrial hyperplasia or malignancy were excluded from the study. Patient demographics (e.g., age, parity, body mass index [BMI]), medical history, and clinical presentation were obtained for analysis. RESULTS: In total, 262 patients were diagnosed with NEH, of which 18.3% (n=48) underwent hysterectomy as first-line management. The average time to surgery was 77.0±35.7 days. All cases were diagnosed by dilation and curettage, and hysteroscopy. The mean age was 51 years, and the mean BMI was 26.9±5.8 kg/m2. Histology from the hysterectomy specimen showed 9 (18.8%) patients with atypical hyperplasia and 2 (4.2%) with grade 1, stage 1A endometrioid adenocarcinoma. Patients with higher grade final pathology had significantly lower median parity (1 vs. 2, P=0.039), higher mean BMI (30.1±6.5 vs. 25.9±5.3 kg/m2, P=0.033), and BMI ≥30 kg/m2 (54.5% vs. 13.5%, P=0.008, odds ratio 7.68), compared to patients whose final histology showed NEH or no residual hyperplasia. CONCLUSION: Occult endometrial atypia and malignancy were found in 18.8% and 4.2% of patients with an initial diagnosis of NEH, respectively. High BMI and low parity were identified as significant risk factors for high-grade endometrial lesions in patients with NEH.

Perception and Feelings of Antenatal Women during COVID-19 Pandemic: A Cross-Sectional Survey.

INTRODUCTION: To assess the level of anxiety and knowledge regarding COVID-19 amongst antenatal women. MATERIALS AND METHODS: This cross-sectional survey was conducted in the antenatal clinics of KK Women's and Children's Hospital, Singapore, from 31 March to 25 April 2020 to assess pregnant women's knowledge of COVID-19, their perceptions of its impact upon pregnancy and psychological impact using the validated Depression, Anxiety, and Stress Scales (DASS-21). RESULTS: Of the 324 women who participated in the study, the mean age was 31.8 years (range, 20-45). The majority (53.7%) were multiparous with mean gestational age of 23.4 weeks (SD 10). The commonest sources of information were Internet-based social media platforms. A significant proportion were unaware, or associated COVID-19 infection during pregnancy with fetal distress (82.1%), intrauterine death (71.3%), fetal anomalies (69.8%), miscarriages (64.8%), preterm labour (67.9%) and rupture of membranes (61.4%). A total of 116 (35.8%) women screened positive for anxiety, 59 (18.2%) for depression, and 36 (11.1%) for stress. There was a significant association between household size and stress scores [B = 0.0454 (95% CI, 0.0035-0.0873)]. Women who associated COVID-19 infection with fetal anomalies and intrauterine fetal death had significantly higher anxiety scores [B = -0.395 (95% CI, -0.660 to -0.130) and B = -0.291 (95% CI, -0.562 to -0.021) respectively]. CONCLUSION: Our study highlights that a lack of timely and reliable information on the impact of COVID-19 on pregnancy and its outcomes results in increased levels of depression, anxiety and stress. The healthcare provider must address these issues urgently by providing evidence-based information using Internet-based resources and psychological support.

A Rare Case of Ovarian Follicular Lymphoma: Incidental Finding in a Woman With Postmenopausal Bleeding.

Ovarian lymphoma is an uncommon malignancy with the incidence of primary ovarian lymphoma being ever rarer. Majority of patients with ovarian lymphoma tend to present with symptoms of abdominal distension, abdominal pain, loss of weight or appetite, and are usually found to have an ovarian mass. Postmenopausal bleeding (PMB) is not a symptom that is usually associated with ovarian pathology. This case report gives an account of how the patient presented to us, and the investigations and treatments offered that led to the final outcome.

Undiagnosed Abdominal Term Pregnancy with Good Neonatal Outcome.

Abdominal pregnancy is a rare occurrence and it represents only 1% of ectopic pregnancy. We report a case of an abdominal pregnancy that resulted in a term live baby. Diagnosis is unsurprisingly difficult in advanced gestation. A high index of suspicion detailed clinical and imaging examinations are needed to make the diagnosis. Multidisciplinary team involvement is crucial in the management of abdominal pregnancy.

A sustainable model to improve maternal health and promote early obstetric care in resource-poor regions.

OBJECTIVE: To design and examine the feasibility of a sustainable training program to build local capacity and improve obstetric outcomes in Kampong Chhnang, Cambodia. METHODS: A "train-the-trainers" model was used to conduct an obstetrics course between 2012 and 2015, its aim to reduce maternal mortality and morbidity. All Cambodian healthcare providers trained by the program were included in the study. The obstetric outcomes of all patients under the care of the trained healthcare providers were analyzed retrospectively to assess the feasibility of the program. Data from all three hospitals and 42 health centers in the province that the trainees worked at were collected from case logs. RESULTS: There was a significant increased trend in recognition of cases of postpartum hemorrhage and pre-eclampsia, and occurrence of difficult deliveries and cesarean deliveries (P<0.001). The maternal mortality ratio decreased from 64.7 per 100 000 deliveries in 2012 to 40.8 per 100 000 deliveries in 2016. CONCLUSION: This sustainable model has the potential to positively impact obstetric education and maternal outcomes and could be adopted in other resource-poor countries, particularly in Southeast Asia.
