OBJECTIVES
To validate a method in detecting SARS-CoV-2 via RT-qPCR in pregnant and non-pregnant samples other than nasopharyngeal swabs and/or oropharyngeal swabs such as cervical, rectal, amniotic fluid, placental, umbilical cord blood, and breastmilk.
METHODSWe performed a validation experiment using MGI easy extraction kits and BGI PCR kits on non-conventional specimens, including cervical, rectal, amniotic fluid, placental, umbilical cord blood, and breastmilk to detect and confirm the presence of SARS-CoV-2. In addition, we tested the validated method on 572 purposively sampled field-collected non-conventional specimens from a cohort of 109 unvaccinated pregnant and 47 unvaccinated non-pregnant women to assess which candidate non-conventional maternal- and fetal-associated specimens may contribute to maternal-fetal viral vertical transmission.
RESULTSPositive detection of SARS-CoV-2 viral RNA in non-conventional specimens was demonstrated and verified. Of the 572 non-conventional samples tested, 1.8% (10/572) were positively validated by RT-qPCR for SARS-CoV-2 in the maternal-associated specimens particularly the rectal (5), placental (1), and cervical (4) swabs among six pregnant and four non-pregnant individuals. In contrast, no SARS-CoV-2 viral RNA was detected in fetal-associated specimens.
CONCLUSIONThe results of the validation study may serve as an additional diagnostic screening layer to support maternal-child care. Furthermore, viral detection in these non-conventional maternal specimens may also be utilized to provide guidance in the clinical management of neonates, and pregnant women during delivery.

Protein S deficiency causing arterial ischemic stroke during pregnancy is uncommon. Delay or omission of treatment with perfusion therapies may worsen outcomes for both the mother and the fetus. In this paper, we report a case of an early pregnant woman with protein S deficiency and multiple history of chronic cerebrovascular disease who underwent successful thrombolysis and mechanical thrombectomy. The patient is a 35-year-old woman, eight weeks pregnant, with a history of protein S deficiency and chronic cerebrovascular disease, presenting with rightsided weakness and aphasia. Initial National Institutes of Health Stroke Scale was 10 with cranial magnetic resonance imaging findings of acute infarcts on the left caudate, lentiform nucleus, insula, and frontal lobe with a large vessel occlusion on the proximal M1 segment of the left middle cerebral artery. Intravenous thrombolysis and mechanical thrombectomy were performed with complete recanalization. The patient improved and delivered without any complications after 8 months. Protein S deficiency can contribute to arterial thrombosis including ischemic stroke. Arterial ischemic stroke and large vessel occlusion can cause significant disability if not treated appropriately. Reperfusion therapies in pregnant women show favorable outcomes and should be performed if the benefits outweigh the risks.

Pregnancy is a critical period in every woman's life. The health of both the mother and her unborn child is at stake, with poor access to needed prenatal care services. Obtaining prenatal care is affected by the pregnancy literacy of the expectant mother. However, the assessment tool for health literacy among Filipino pregnant women is limited. This paper aimed to examine existing maternal health literacy instruments. Hopefully, an adopted tool can be found for assessing prenatal health literacy. After examining existing maternal health literacy tools, 18 questions were suggested that can be further modified before they are used for Filipino pregnant women to assess their prenatal health literacy.

OBJECTIVE:
This study explored whether thyroglobulin and thyroid disease prevalence rates were higher in pregnant Chinese women with a median urinary iodine concentration of 100-149 µg/L, compared with those with a median urinary iodine concentration of 150-249 μg/L maintained through sustainable universal salt iodization.
METHODS:
This was a cross-sectional study in which 812 healthy pregnant women were enrolled to collect samples of their household edible salt, urine, and blood during their routine antenatal care in the 18 counties in Fujian Province, China. The levels of salt iodine concentration, urinary iodine concentration (UIC), free triiodothyronine (FT3), free thyroid hormone (FT4), thyroid-stimulating hormone (TSH), thyroglobulin (Tg), thyroid peroxidase antibody and thyroglobulin antibody were assessed during the routine antenatal care visits.
RESULTS:
The median UIC (mUIC) in pregnant women was 130.8 μg/L (interquartile range = 91.5-198.1 μg/L) in the counties with an mUIC of 100-149 μg/L (Group I), and 172.0 μg/L (interquartile range = 123.5-244.4 μg/L) in the counties with an mUIC of 150-249 μg/L (Group II). Goiter prevalence and thyroid nodule detection rates showed no difference between Group I and Group II ( P > 0.05). Except for FT4 values, the TSH, FT4, FT3, Tg and Tg values > 40 (μg/L) and the thyroid diseases prevalence rate (TDR) showed no significant differences between Group I and Group II ( P > 0.05), whether or not iodine supplementation measures were taken.
CONCLUSION
Compared with an mUIC of 150-249 μg/L, not only there was no difference in thyroid morphology, but also the Tg value, rate of Tg values > 40 µg/L, and TDR were not higher in pregnant women in the counties with an mUIC of 100-149 μg/L achieved through sustainable universal salt iodization in Fujian Province, China.

Objective: Exploring the mediating effect of perceived social support between the maternal personality traits and pregnancy-related anxiety. Methods: Singleton pregnant women who underwent antenatal checkups in the obstetrics department of general hospital affiliated to Ningxia Medical University from July to December 2021 were enrolled in this study to investigate perceived social support, pregnancy-related anxiety and conscious personality traits. Pearson correlation analysis was used to analyze the association between the maternal personality traits, perceived social support, and pregnancy-related anxiety, and the mediating effect of perceived social support was analyzed using Bootstrap method. Results: A total of 1 259 subjects were included in the study, of which 170 (13.50%) pregnant women felt introverted. The total score of perceived social support was (46.37±8.38), and 31.45% of pregnant women had high perceived social support. The total score of pregnancy-related anxiety was (21.48±5.53). The score of worry about fetal health was (10.09±3.24), and 368 (29.23%) of pregnant women had pregnancy-related anxiety. Maternal personality traits and pregnancy-related anxiety were negatively correlated (r=-0.076, P<0.05) and positively correlated with perceived social support during pregnancy (r= 0.127, P<0.05). Perceived social support during pregnancy and pregnancy-related anxiety were negatively correlated (r=-0.236, P<0.05). Perceived social support partially mediated the relationship between the maternal personality traits and pregnancy-related anxiety, with a relative effect value of 37.50%. Conclusion: The maternal personality traits, level of perceived social support and pregnancy-related anxiety are all related. Perceived social support could mediate the relationship between the maternal personality traits and pregnancy-related anxiety.

OBJECTIVE:
To carry out genetic testing and prenatal diagnosis for a woman featuring moderate intellectual disability (ID).
METHODS:
The patient had presented at the First Affiliated Hospital of Zhengzhou University on April 28, 2021. With informed consent, peripheral blood and amniotic fluid samples were collected for the extraction of genomic DNA. Pathogenic copy number variations (CNVs) were detected with CNV-seq, and single gene variants were detected by whole exome sequencing (WES) and Sanger sequencing. Candidate variant was verified by Sanger sequencing, and CNV-seq and multiplex ligation-dependent probe amplification (MLPA) were used to detect fetal CNVs.
RESULTS:
The 23-year-old woman had moderate ID, sideway walking, and unstable holding. Ultrasonography at 18+3 weeks' gestation had revealed no fetal abnormality. No pathogenic CNV was detected in the woman by CNV-Seq, while WES revealed that she has harbored a heterozygous c.1675C>T (p.Arg559*) variant of the DLG4 gene, which was verified by Sanger sequencing. Based on guidelines from the American College of Medical Genetics and Genomics, the variant was predicted to be likely pathogenic (PVS1+PM2_supporting). Sanger sequencing has confirmed that the fetus has inherited this variant, and CNV-Seq also revealed that that fetus has harbored a 0.1 Mb heterozygous deletion at Xp21.1, which has encompassed the DMD gene, and the result was verified by MLPA.
CONCLUSION
The heterozygous c.1675C>T variant of the DLG4 gene probably underlay the mental retardation in this woman, and her fetus was found to harbor the same variant in addition with deletion of the DMD gene, which may predispose to ID type 62.

OBJECTIVE:
This study aimed to evaluate the effects of a mindfulness-based psychosomatic intervention on depression, anxiety, fear of childbirth (FOC), and life satisfaction of pregnant women in China.
METHODS:
Women experiencing first-time pregnancy ( n = 104) were randomly allocated to the intervention group or a parallel active control group. We collected data at baseline (T0), post-intervention (T1), 3 days after delivery (T2), and 42 days after delivery (T3). The participants completed questionnaires for the assessment of the levels of depression, anxiety, FOC, life satisfaction, and mindfulness. Differences between the two groups and changes within the same group were analyzed at four time points using repeated-measures analysis of variance.
RESULTS:
Compared with the active control group, the intervention group reported lower depression levels at T2 ( P = 0.038) and T3 ( P = 0.013); reduced anxiety at T1 ( P = 0.001) and T2 ( P = 0.003); reduced FOC at T1 ( P < 0.001) and T2 ( P = 0.04); increased life satisfaction at T1 ( P < 0.001) and T3 ( P = 0.015); and increased mindfulness at T1 ( P = 0.01) and T2 ( P = 0.006).
CONCLUSION
The mindfulness-based psychosomatic intervention effectively increased life satisfaction and reduced perinatal depression, anxiety, and FOC.

Systemic lupus erythematosus (SLE) is an autoimmune connective tissue disease that affects multiple organs and systems. It is more common in women of childbearing age. Compared with the general population, pregnant women with SLE are at a significantly increased risk of adverse perinatal outcomes such as preterm birth and intrauterine growth restriction. In addition, the offspring of SLE patients may also be adversely affected by in utero exposure to maternal autoantibodies, cytokines, and drugs. This article summarizes the long-term developmental outcomes of offspring of pregnant women with SLE in terms of the blood system, circulatory system, nervous system, and immune system.

OBJECTIVES:
Pregnancy stress is the psychological confusion or threat caused by various stress events and adverse factors during pregnancy. Pregnant women exposed to many stressors, they will be easy to produce bad mood and prenatal depression if they cannot adapt to their own changes. Prenatal depression is one of the major global public health problems, with a higher incidence in developing countries and a negative impact on the health of pregnant women and fetus. Resilience refers to pregnant women using their own positive psychological capital, can self-emotional adjustment and improve their ability to adapt to the response state. A better level of resilience can enable pregnant women to face various negative and adaptive problems positively. This study aims to investigate the relationship between pregnancy stress, resilience and prenatal depression through a mental health survey of pregnant women.
METHODS:
A total of 750 pregnant women in a Grade A tertiary hospital in Urumqi were investigated by self-designed demographic questionnaire, Pregnancy Pressure Scale (PPS) and Patient Health Questionnaire-9 (PHQ-9), Connor-Davidson Resilience Scale (CD-RISC), and the levels of stress during pregnancy, prenatal depression and resilience were analyzed. Pearson correlation analysis was used to explore the correlation between the three. Bootstrap mediation effect test was used to test the mediation effect relationship among the three. If the mediation effect was confirmed, AMOS software was used to establish the mediation effect structural equation model to analyze the mediation effect among the three.
RESULTS:
Among 750 respondents, 709 (94.53%) had mild or above pregnancy pressure, 459 (61.20%) had mild or above depressive symptoms and 241 (32.13%) had a good or above level of resilience. Pearson correlation analysis showed that prenatal depression was significantly positively correlated with pregnancy stress (P<0.01), prenatal depression and pregnancy stress were significantly negatively correlated with resilience (all P<0.01). Mediation effect test analysis showed that all the pathways were statistically significant (P<0.01). Mediation effect of resilience between pregnancy stress and prenatal depression was significantly found (95% CI 0.022-0.068, P<0.001). Pregnancy pressure negatively affected resilience (β=-0.38, P<0.01), and resilience negatively affected prenatal depression (β=-0.10, P<0.01). The mediation effect of resilience was 6.5%.
CONCLUSIONS
Pregnant women's pregnancy pressure, resilience and prenatal depression are significantly correlated, and the mediation variable resilience plays a partial mediating role in the impact of pregnancy pressure on prenatal depression. Pregnant women can reduce the incidence of prenatal depression and promote their physical and mental health by exercising their resilience.

Aims:
Due to the world's direction of alternative medicine and herbal medication, tea leaves have been employed to inhibit certain bacteria that cause urinary tract infections (UTIs). This study aimed to evaluate the effect of green, red and black tea as antibacterial against UTIs in pregnant women and changes in blood pressure and iron level in the blood of their women.
Methodology and results:
Forty-eight isolates were isolated from 50 women suffering from urinary tract infections, Staphylococcus aureus (18) 37.5%, Escherichia coli (15) 31.25%, Pseudomonas aeruginosa (8) 16.6%, Klebsiella sp. (5) 10.4% and Enterobacter sp. (2) 4.16%. The sensitivity of bacteria to the antibiotics Amikacin, Amoxicillin/Clavulanic, Ampicillin/Sulbactam, Cefixime, Ceftriaxone, Ciprofloxacin, Imipenem, Nitrofurantion, Penicillin and Tetracycline were tested, while E. coli and P. aeruginosa (8), Enterobacter sp. were resistance for Ceftriaxone and Amoxicillin /Clavulanic (100%). While Enterobacter sp. is sensitive to Nitrofurantoin and Imipenem (100%). The ability of the isolates to form biofilms was tested using the Congo red agar method and the micro titrations plate method. The results showed that not all isolates have the ability to produce biofilms and red tea is the most powerful antibacterial under study. Drinking green tea for two weeks regularly in pregnant women who suffer from high blood pressure showed an improvement in blood pressure, as it became normal 118/78 and with the normal iron level in the blood at a rate of hemoglobin = 11.8, while drinking red tea did not change blood pressure measurements in pregnant women with high blood pressure.
Conclusion, significance and impact of study
The effect of red tea extract was stronger than other teas used in the study as an antibacterial against urinary tract bacteria. Regular consumed of green tea helps regulate blood pressure, especially for pregnant women who are at risk of hypertension during pregnancy.
