Aims/Introduction: To evaluate the effect of probiotic supplements on insulin resistance in pregnant women with diet‐controlled gestational diabetes mellitus.Materials and Methods: A randomized, double‐blind, placebo‐controlled trial was carried out between June 2016 and February 2017. Pregnant women with diet‐controlled gestational diabetes mellitus were enrolled in the study at 24–28 weeks‐of‐gestation and randomized to receive either probiotic supplements containing Bifidobacterium and Lactobacillus or a placebo daily for four consecutive weeks. Primary outcomes were mean differences in insulin resistance (homeostatic model assessment for insulin resistance), fasting insulin and fasting plasma glucose between the two groups. Secondary outcomes were changes in maternal weight after the intervention.Results: Data from 28 patients in the probiotic group and 29 in the placebo group were analyzed. The changes in metabolic parameters after randomization showed significant improvement in glucose metabolism in the probiotic group compared with the placebo group, including fasting plasma glucose (0.68 ± 5.88 vs 4.620 ± 7.78 mg/dL, mean difference −3.94 mg/dL, 95% confidence interval −7.62, −0.27, P = 0.034), fasting plasma insulin (1.11 ± 1.71 vs 3.77 ± 1.70 mIU/L, mean difference −2.67 mIU/L, 95% confidence interval −3.57, −1.76, P = 0.001) and homeostatic model assessment for insulin resistance (0.25 ± 0.37 vs 0.89 ± 0.46, mean difference −0.63, 95% confidence interval −0.86, −0.41, P = 0.001). Weight gain during randomization was similar between the two groups.Conclusions: Four weeks of probiotic supplements in women with diet‐controlled gestational diabetes in the late second and early third trimester lowered fasting glucose and increased insulin sensitivity. Probiotic supplements may be considered as an adjunct treatment for glycemic control in these patients.

Newborn screening (NBS) is a public health service that is used to screen for treatable conditions in many countries, including Thailand. Several reports have revealed low levels of parental awareness and knowledge about NBS. Because of limited data on parental perspectives toward NBS in Asia and the differences in socio-cultural and economic contexts between Western and Asian countries, we conducted a study to explore parental perspectives on NBS in Thailand. A Thai questionnaire to assess awareness, knowledge, and attitudes regarding NBS was constructed. The final questionnaire was distributed to pregnant women, with or without their spouses, and to parents of children aged up to one year who visited the study sites in 2022. A total of 717 participants were enrolled. Up to 60% of parents were identified as having good awareness, which was significantly associated with gender, age, and occupation. Only 10% of parents were classified as having good knowledge relative to their education level and occupation. Providing appropriate NBS education should be initiated during antenatal care, focusing on both parents. This study noted a positive attitude toward expanded NBS for treatable inborn metabolic diseases, incurable disorders, and adult-onset diseases. However, modernized NBS should be holistically evaluated by multiple stakeholders in each country because of different socio-cultural and economic contexts.

The rate of termination of pregnancy (TOP) for fetal anomalies and the factors affecting TOP vary among different populations. Optimisation of prenatal care and counselling requires understanding the factors influencing parental decisions in the relevant population. This study aimed to evaluate the rate of TOP after diagnoses of major fetal anomalies and assess factors associated with TOP-related decisions at a university hospital in Thailand. A retrospective chart review was conducted at the Fetal Anomaly Clinic of Ramathibodi Hospital, Bangkok, Thailand. Medical records of all women with singleton pregnancies prenatally diagnosed with major fetal anomalies before 24 gestational weeks between 2010 and 2020 were reviewed. During the study period, 461 cases of major fetal anomalies were diagnosed, and 264 (57.3%) of these pregnancies were terminated. Three factors influencing parental TOP decisions were lethal anomalies (odds ratio [OR], 197.39; 95% confidence interval [CI], 49.95–779.95; p < 0.001), presence of genetic abnormalities (OR, 10.19; 95% CI, 4.17–24.87; p < 0.001) and gestational age at diagnosis (OR, 0.74; 95% CI, 0.65–0.84; p < 0.001). Over half of the pregnant women whose records were reviewed and who were prenatally diagnosed with major fetal anomalies terminated their pregnancies. Fetal factors, particularly lethality, genetic abnormalities and early gestational age at diagnosis, showed the most powerful associations with parental TOP decisions. Other maternal background factors were not key considerations.

Noonan syndro me is a rare autosomal dominant congenital abnormality associated with a gene defect located on the short arm of chromosome 12. It is characterized by dysmorphic facies, webbed neck, short stature, lymphatic obstruction, cardiac anomalies, and intellectual disability. Prenatal diagnosis of Noonan syndrome is rare because there are no pathognomonic sonographic signs. Studies on the prenatal sonographic features of Noonan syndrome have been reported in very limited numbers. This case series of severe fetal Noonan syndrome, together with a literature review, was conducted to establish prenatal sonographic features highly suggestive of Noonan syndrome to facilitate early detection by clinicians. This study reveals that Noonan syndrome has a relatively specific pattern, which facilitates prenatal molecular genetic diagnosis. Increased nuchal translucency (NT) in the late first trimester and fluid collection in the early second trimester could be warning signs for follow-up, prompting further investigation to detect late-onset features and leading to molecular genetic confirmation. Most structural abnormalities appear in the second trimester, with progressive changes noted throughout gestation. This review better characterizes the sonographic features of fetal Noonan syndrome based on a larger sample size, illustrating a wider spectrum of prenatal phenotypes, including lymphatic drainage disorders, cardiac abnormalities, polyhydramnios, and absent ductus venosus.

Background: In developing countries, pregnant women have insufficient knowledge about cell-free DNA screening. Reports from developed countries have found that various tools in prenatal genetic counseling can improve the knowledge of pregnant women who undergo cell-free DNA screening. Data are limited from developing countries where women have different baseline socio-educational backgrounds. The objective of this study was to compare the effects of an animated educational video combined with traditional counseling versus traditional counseling alone in changing pregnant women’s knowledge of cell-free DNA screening. Methods: This study was a randomized control trial at an antenatal clinic. Eligible subjects who were Thai pregnant women, were randomized to either view or not view the 4-minute animated educational video explaining cell-free DNA screening. Both groups received traditional counseling. The women were asked to complete a Thai questionnaire assessing knowledge of the screening before and after intervention. The questionnaire consisted of three sections: demographic data of the research participants and their existing awareness about cell-free DNA testing; performance and limitations of cell-free DNA screening; and participants’ attitudes toward the positive screening. Primary outcome was the change in knowledge scores. Secondary outcomes were attitudes toward positive screening test, levels of satisfaction with counseling, and screening acceptance rates. Results: Data from 83 women in the video group and 82 in the non-video group were analyzed. The knowledge score (range 0–18) change after counseling was significantly higher in the video group than the non-video group (+ 7.1 ± 3.3 vs + 4.2 ± 2.5; p = 0.03). There were no significant differences in attitudes toward positive screening test (p = 0.83), levels of satisfaction (p = 0.24), or screening acceptance rates (p = 0.15) between the groups. Conclusions: Adding the video to traditional counseling was better than traditional counseling alone in improving pregnant women’s knowledge about cell-free DNA screening. Trial registration: The study was retrospectively registered with the Thai Clinical Trials Registry (TCTR20210917001, 17/09/2021).
