BACKGROUND
Dietary fiber (DF) consumption was reported to improve insulin sensitivity, change the tryptophan metabolism, and alter the gut microbiota. Herein, this study aimed to investigate the effects of DF consumption on insulin sensitivity, tryptophan metabolism, and gut microbiota composition in sows during late pregnancy, and explore the relationship between tryptophan metabolites and insulin sensitivity regulated by DF supplementation.
RESULTS
Twelve sows were randomly assigned to two dietary treatment groups (six/group): the low-fiber (LF) group, which was fed a basal diet, and the high-fiber (HF) group, which was fed the basal diet supplemented with 22.60 g/kg inulin and 181.60 g/kg cellulose. During late pregnancy, meal test, glucose tolerance test, and insulin challenge test were used to investigate the insulin sensitivity of sows, using the percutaneous brachiocephalic vein catheterization technique. High DF consumption resulted in improved insulin sensitivity, especially during the second and third trimesters, and promoted serotonin production from tryptophan. Additionally, plasma serotonin concentration was positively correlated with the insulin sensitivity index during late pregnancy. Moreover, DF consumption elevated fecal short-chain fatty acid (SCFA) concentrations, altered fecal microbial diversity, and increased the abundances of Rikenellaceae_RC9_gut_group, Alloprevotella, Parabacteroides, Roseburia, and Sphaerochaeta, which were positively correlated to plasma serotonin concentration.
CONCLUSIONS
DF consumption improved insulin sensitivity during late pregnancy in sows, which improved microbial diversity in fecal samples and increased fecal SCFA concentrations, resulting in a positive correlation with plasma serotonin level.

BACKGROUND
Premutations in the Fragile X Messenger Ribonucleoprotein 1 (FMR1) gene, defined as between 55 and 200 CGGs, have been implicated in fragile X-associated primary ovarian insufficiency (FXPOI). Only 20% of female premutation carriers develop early ovulatory dysfunction, the reason for this incomplete penetrance is unknown. This study validated the mathematical model in premutation alleles, after assigning each allele a score representing allelic complexity. Subsequently, allelic scores were used to investigate the impact of allele complexity on age at amenorrhea for 58 premutation cases (116 alleles) previously published.
METHODS
The allelic score was determined using a formula previously described by our group. The impact of each allelic score on age at amenorrhea was analyzed using Pearson's test and a contour plot generated to visualize the effect.
RESULTS
Correlation of allelic score revealed two distinct complexity behaviors in premutation alleles. No significant correlation was observed between the allelic score of premutation alleles and age at amenorrhea. The same lack of significant correlation was observed regarding normal-sized alleles, despite a nearly significant trend.
CONCLUSIONS
Our results suggest that the use of allelic scores combination have the potential to explain female infertility, namely the development of FXPOI, or ovarian dysfunction, despite the lack of correlation with age at amenorrhea. Such a finding is of great clinical significance for early identification of females at risk of ovulatory dysfunction, enhancement of fertility preservation techniques, and increasing the probability for a successful pregnancy in females with premutations. Additional investigation is necessary to validate this hypothesis.

Observational Study
BACKGROUND
Experiencing childbirth as traumatic is common and can have long-lasting negative consequences for women's mental health. However, fostering a sense of social identity has been shown to protect psychological wellbeing and mental health during life transitions, such as entering parenthood. This study therefore investigated the relationship between traumatic childbirth and first-time mothers' social identity and their psychological wellbeing, and more specifically whether strength of identity as a first-time mother protected psychological wellbeing following traumatic childbirth.
METHOD
Women over the age of 18 who were living in the UK and had given birth to their first child in the past nine months were recruited to the study from clinical and community settings. They completed digital self-report questionnaires about their birth experience, social identity, mental health, and psychological wellbeing. Women who perceived themselves to have had a traumatic birth (the trauma group; N = 84) were compared to women who did not perceive themselves to have had a traumatic birth (the control group, N = 39). T-tests and chi square tests assessed preliminary group differences before multivariate analyses of covariance controlled for covariates. Post-hoc tests identified the direction of differences. Multiple regression and moderation analyses analysed interaction effects.
RESULTS
The trauma group had significantly lower psychological wellbeing (mean = 41.5, 95% CI [39.4-43.7], p = .008, partial η = 0.059), compared to the control group (mean = 48.4, 95% CI [45.3-51.5]), but the two groups did not differ in the strength of their first-time mother identity, which was high across both groups. Strength of identity did not moderate the relationship between traumatic childbirth and psychological wellbeing. Giving birth by caesarean section independently reduced the strength of the first-time mother identity (p = .017, partial η = 0.049). All analyses controlled for emotional and practical support, perceptions of healthcare staff, and mode of birth.
CONCLUSIONS
Having a traumatic birth was associated with lower psychological wellbeing, and the strength of first-time mother identity does not appear to moderate this relationship. Factors such as mode of birth may be more important. Further research, including longitudinal designs, is needed to understand the relationship between these constructs and identify more effective ways of protecting first-time mothers' mental health.

Observational Study
Preeclampsia (PE) is a serious condition that threatens pregnancy with severe sequelae on both the mother and infant. Early detection of PE will lead to favorable outcomes, and using readily available markers like hematological indices is an attractive choice. Examine the diagnostic utility of hematological indices in pregnant women to predict preeclampsia and its severity. In a retrospective case-control study that included 252 women, all had their complete blood picture evaluated during their first and third trimesters as part of their outpatient antenatal care during their pregnancy. They were also divided into 3 groups: healthy pregnant women (control), non-severe PE, and severe PE, each involving 84 women. The changes in platelet to lymphocyte ratio (PLR) between 1st and 3rd trimesters showed an excellent ability to differentiate between severe PE and control (area under the curve = 0.954, cutoff ≤ -5.45%) and a good ability to differentiate between severe PE and non-severe PE (area under the curve = 0.841, cutoff ≤ -7.89%). Neutrophil to lymphocyte ratio showed a good to excellent ability to differentiate between severe PE and non-severe PE compared to control in the first and third trimesters and the percentage change between them. Changes in neutrophil to lymphocyte ratio and PLR strongly predict preeclampsia and its severity since they offer more predictive values than measuring NLP and PLR at different stages of pregnancy individually.

Observational Study
In China, the implementation of 2-child policy since 2015 entitles increasing number of advanced maternal age. Recently, Chinese hypertensive disorders of pregnancy (HDP) in advanced-age women have attracted significant clinical and epidemiological research interest. Previous studies have shown an association between serum uric acid (SUA) levels and low birth weight (LBW) in children. Several studies have reported that advanced maternal age is a risk factor for many complications in pregnancy, including LBW. However, it remains unclear whether SUA affects LBW risk in advanced maternal age mothers with hypertensive diseases. The study was observational in nature. A total of 692 advanced maternal age with hypertension were enrolled in our study. A variety of demographic and vital sign data, laboratory test results, and pregnancy outcomes were collected. Children born with LBW served as the clinical endpoint. On admission, blood samples were taken, and women with advanced maternal ages were divided into 2 groups based on their SUA levels. In order to investigate the association between SUA and LBW, a logistic regression model was used. E-value analysis was used to determine the residual unmeasured confounding. The mean SUA level was increased in advanced maternal age patients with HDP. Of 692 newborns, 244 (35.26%) have LBW. With possible confounders adjusted, high SUA levels were independent risk factors for LBW (odds ratio [OR]2.88, 95% confidence intervals [CI]1.22-6.81), multivariate logistic regression analysis using SUA as a continuous variable recapitulated the pattern (OR 1.01, 95% CI 1.00-1.01). In addition, SUA levels in women with advanced maternal age and hypertension were linearly related to LBW incidence. According to this study, SUA levels in patients with advanced maternal age and HDP are associated with LBW incidence.

Observational Study
The study aimed to determine the characteristics of comorbidities, association between comorbidities and coronavirus disease 2019 (COVID-19), as well as characteristics of COVID-19 severity among pregnant women at a tertiary hospital in Bandung. We conducted a cross-sectional study by taking secondary data between January 2020 and December 2021 involving 278 pregnant women aged 16 to 45 years that confirmedly diagnosed with COVID-19 via RT-PCR. We collected information from the medical record on severity and comorbidities. The admission C-reactive protein (CRP) profiles were compared between the severe and nonsevere COVID-19 patients. This study employed bivariate analysis, t test, and multivariate analysis with logistic regression models. Of the 278 data included in this study, 120 cases had comorbidities. Most patients were asymptomatic (82%). Obesity was the most common comorbid proportion. Only hypertension as comorbid showed a significant association with symptomatic or asymptomatic COVID-19 (<0.05). Pregnant women with hypertension were 6 times more likely to show symptoms than those without hypertension (OR = 6.092; 95% CI 3.103-11.962). Pregnant women with comorbidities were at higher risk of cesarean sections and stillbirth. The CRP levels which were found to have statistically significant association with COVID-19 severity (<0.05). The domination of asymptomatic COVID-19 in pregnant women was found in this study. Hypertension comorbid has a significant association with COVID-19 symptoms. Maternal and neonatal outcomes appear to be influenced by maternal comorbidities. Moreover, the CRP levels were found to be significant risk factors for COVID-19 severity in pregnant women that might have association with comorbidities.

BACKGROUND
Early detection and intervention of hearing issues in newborns are crucial for their auditory and speech development, necessitating newborn hearing screenings. This study aimed to investigate the impact of delivery methods, specifically natural delivery and cesarean section, on newborn hearing screening outcomes.
METHODS AND MATERIAL
A retrospective analysis was conducted on data from 600 newborns delivered at The First Affiliated Hospital of Shaoyang University between January 2020 and January 2023. The initial hearing screenings used the AccuScreen otoacoustic emission instrument. The study examined the influence of delivery method on the pass rates of newborns' first hearing screenings within and beyond 48 h postbirth.
RESULTS
The pass rates for the initial hearing screenings, conducted within and after 48 h of birth, were significantly higher in the natural delivery group compared to the cesarean section group (P < 0.05). Furthermore, multivariate analysis identified the delivery method as a significant factor influencing the pass rates of newborns' first hearing screenings.
CONCLUSIONS
The mode of delivery appears to affect the results of the initial hearing screenings of newborns, though further research is needed to validate these findings.

Meta-Analysis
BACKGROUND
Sudden sensorineural hearing loss (SSNHL) during pregnancy is a rare condition and has not been much studied. The study aimed to perform a systematic review and meta-analysis of the risk factors, complications, and treatment modalities for SSNHL in pregnant women.
MATERIALS AND METHODS
PubMed, Web of Science, Scopus, ProQuest, and Google Scholar were used for the literature search. The Cochrane technique for assessing risk of bias was used for the article quality appraisal, and RevMan 5.4 was used for conducting the meta-analysis. Standard mean difference (SMD) and odds ratios with a 95% confidence interval (95% CI) were utilized. Heterogeneity and publication bias were assessed using the I-square (I2) test statistic and the Egger's test, respectively.
RESULTS AND DISCUSSION
The seven primary studies employed prospective and retrospective study designs. The meta-analysis showed that there were fewer risk variables for SSNHL in the experimental group compared with those in the control group (SMD = -0.45 to 3.24, 95% CI = -3.063.63 to 2.16-2.85), indicating that the analysis revealed an insignificant difference. However, the treated patients presented hearing improvement, suggesting a significant analysis (SMD = -0.6710.20, 95% CI = -1.2713.51 to -0.066.88). Furthermore, after therapy, substantial differences were observed in SMD between the two groups (SMD = -0.7415.18, 95% CI = -1.2423.85 to -0.256.40) in favor of the experimental group patients, based on the analysis results of four included studies. However, the I2-value of 0% showed that the heterogeneity was low.
CONCLUSION
SSNHL during pregnancy is a notably rare condition with an unknown cause. However, hormonal fluctuations, particularly increased levels of estrogen and progesterone during pregnancy, have been frequently implicated as potential triggers for SSNHL.

BACKGROUND
To the best of our knowledge, numerous observational studies have linked pregnancy complications to increased risks of diabetes and cardiovascular disease (CVD), causal evidence remains lacking. Our aim was to estimate the association of adverse pregnancy outcomes with diabetes and cardiovascular diseases.
METHODS
A two-sample Mendelian randomization (MR) analysis was employed, which is not subject to potential reverse causality. Data for pregnancy complications were obtained from the FinnGen consortium. For primary analysis, outcome data on diabetes, related traits, stroke, and coronary heart disease (CHD) were extracted from the GWAS Catalog, MAGIC, MEGASTROKE, and CARDIoGRAMplusC4D consortium. The MAGIC and UKB consortium datasets were used for replication and meta-analysis. Causal effects were appraised using inverse variance weighted (IVW), weighted median (WM), and MR-Egger. Sensitivity analyses were implemented with Cochran's Q test, MR-Egger intercept test, MR-PRESSO, leave-one-out (LOO) analysis and the funnel plot.
RESULTS
Genetically predicted gestational diabetes mellitus (GDM) was causally associated with an increased diabetes risk (OR=1.01, 95% CI=1-1.01, <0.0001), yet correlated with lower 2-hour post-challenge glucose levels (OR=0.89, 95% CI=0.82-0.97, =0.006). Genetic liability for pregnancy with abortive outcomes indicated decreased fasting insulin levels (OR=0.97, 95% CI=0.95-0.99, =0.02), but potentially elevated glycated hemoglobin levels (OR=1.02, 95% CI=1.01-1.04, =0.01). Additionally, hypertensive disorders in pregnancy was tentatively linked to increased risks of stroke (OR=1.11, 95% CI=1.04-1.18, =0.002) and CHD (OR=1.3, 95% CI=1.2-1.4, =3.11E-11). Gestational hypertension might have a potential causal association with CHD (OR=1.11, 95% CI=1.01-1.22, =0.04). No causal associations were observed between preterm birth and diabetes, stroke, or CHD.
CONCLUSION
The findings of this study provide genetic evidence that gestational diabetes, pregnancy with abortive outcomes, and hypertensive disorders in pregnancy may serve as early indicators for metabolic and cardiovascular risks. These insights are pivotal for the development of targeted screening and preventive strategies.

Introduction Domestic violence (DV) in the form of verbal abuse is very common among women, especially pregnant women, posing as a serious public health issue that could lead to complications in pregnancy and threaten maternal and fetal outcomes. Studies have determined that domestic verbal abuse (DVA) in pregnancy was more common in women less than 25 years of age as well as in those with low education levels. This study determined the overall prevalence of verbal abuse in pregnant women, in a semi-urban population and is unique in that the verbal abuse in pregnant women with a previous girl child was also determined. This study helps healthcare providers identify the potential causes of DVA in pregnancy and provide timely interventions in the form of counseling for pregnant women and families. Objective This observational study was carried out to assess the prevalence of DVA among pregnant women, to determine the trimester of occurrence of DVA among pregnant women, and to explore the associations of DVA with age, employment status, parity gestational age, and birth weight. Materials and methods This was a six-month hospital-based observational study conducted at Dr D. Y. Patil Medical College's in-patient department (IPD) of Obstetrics and Gynecology in Pimpri, Pune. Consent was obtained from 200 pregnant women who received admission for delivery and provided a validated modified copy of a DV assessment screening questionnaire. A statistical analysis was performed using GraphPad Prism 10. A Chi-square test was employed wherever required, and a p-value of less than 0.05 was considered significant. Results The study included 200 pregnant women, who were admitted to the hospital for delivery. The prevalence of DV in the form of verbal abuse was noted to be 74 out of 200 (37%). The working status of the woman showed an influence on DVA. There was also a significant increase in verbal abuse (68%) among the age group between 18 and 23 years. The previous delivery of a female child also had a significant impact on DVA, which turned out to be more prevalent, particularly if two female children were born previously (80%). The study also noted higher rates of preterm deliveries in pregnant women with DVA being 57%. Conclusion The study demonstrates that women, even in modern times, experience DVA during pregnancy, especially among the younger age group. It has also been found that it is more common among women who are financially dependent due to maternal unemployment. As a result, there is a need to routinely screen pregnant women for DVA to avoid potentially detrimental pregnancy outcomes and to prevent ongoing abuse.
