Abstract
Background Preterm birth before 37th wk of gestation is called premature birth. Corticotropin-releasing hormone (CRH) and CRH-binding protein (BP) act on various maternal and fetal tissues during pregnancy, such as the myometrium, which regulates the transition from the dormant phase of the uterus to the active phase. Studies have shown that mir-200c and mir-181a interact with CRH and CRH-BP. Objective The present study aimed to investigate the expression of mir-200c, mir-181a, CRH, and CRH-BP in women with a history of preterm birth. Materials and Methods In this case-control study, the gene expression level of mir-200c, mir-181a, CRH, and CRH-BP in placental tissue samples obtained from 48 women with a history of preterm labor was assessed in the Mojibian hospital of Yazd, Iran, from January to March 2023. Differences between mir-200c, mir-181a CRH, and CRH-BP gene expressions among cases and controls were assessed. Results The outcomes indicated that the expression of CRH increased with going on to the regular parturition time (p < 0.001). While outcomes indicated, CRH-BP decreased with going on to the regular parturition time (p < 0.001). In addition, the results showed that the expression of mir-181a increased and mir-200c decreased with approaching the normal delivery time (p < 0.001). Conclusion In conclusion, the expressions of mir-200c, mir-181a, CRH, and CRH-BP were dissimilar in different weeks of gestation. It could be proposed to use mir-200c, mir-181a, CRH, and CRH-BP as biomarkers to weigh the exact delivery time, which could minimize the side effects of preterm labor for the mother and fetus.

Abstract
Background: Intrauterine growth restriction (IUGR) refers to fetuses with an estimated ultrasonography weight below the 10% percentile. Hypoglycemia is a major concern in neonates with IUGR.
Objective: To investigate the relationship between umbilical artery (UA) Doppler ultrasonography and neonate hypoglycemia and IUGR.
Materials and Methods: This was a longitudinal follow-up study consisting of 114 neonates (gestational age of 28-40 wk) born with IUGR in the third trimester of pregnancy at Shahid Sadoughi Hospital, Yazd, Iran between May 2016 and October 2017. The neonates were assigned into three subgroups of normal UA Doppler, absent end-diastolic flow (EDF) in UA Doppler, and reverse EDF in UA Doppler. The blood glucose of the neonates was checked one, two, three, six, 12, 24 and 48 hr after birth, and the neonates were placed in the hypoglycemia or euglycemia groups according to guidelines.
Results: Out of the 114 neonates included in the study, 75 (65.8%) had normal UA Doppler, 29 (25.4%) had absent EDF in UA Doppler, and 10 (8.8%) had reverse EDF in UA Doppler. There was a significant difference in the mean blood glucose in the first hr between the normal UA Doppler group and the reverse EDF in UA Doppler group (p < 0.01).
Conclusion: Postnatal hypoglycemia in neonates with IUGR is associated with the result of UA Doppler ultrasonography during pregnancy.
Key words: Growth restriction, Hypoglycemia, Ultrasonography Doppler, Umbilical artery.

Abstract
Cell-based therapy with CD4+ FOXP3+ regulatory T cells (Tregs) is a promising strategy to limit organ rejection and graft-vs-host disease. Ongoing clinical applications have yet to consider how human Tregs could be modified to direct their migration to specific inflammation sites and/or tissues for more targeted immunosuppression. We show here that stable, homing-receptor-tailored human Tregs can be generated from thymic Tregs isolated from pediatric thymus or adult blood. To direct migration to Th1-inflammatory sites, addition of interferon-γ and IL-12 during Treg expansion produced suppressive, epigenetically stable CXCR3+ TBET+ FOXP3+ T helper (Th)1-Tregs. CXCR3 remained expressed after injection in vivo and Th1-Tregs migrated efficiently towards CXCL10 in vitro. To induce tissue-specific migration, addition of retinoic acid (RA) during Treg expansion induced expression of the gut-homing receptors α4β7-integrin and CCR9. FOXP3+ RA-Tregs had elevated expression of the functional markers latency-associated peptide and glycoprotein A repetitions predominant, increased suppressive capacity in vitro and migrated efficiently to healthy and inflamed intestine after injection into mice. Homing-receptor-tailored Tregs were epigenetically stable even after long-term exposure to inflammatory conditions, suppressive in vivo and characterized by Th1- or gut-homing-specific transcriptomes. Tailoring human thymic Treg homing during in vitro expansion offers a new and clinically applicable approach to improving the potency and specificity of Treg therapy.

Abstract
Quince (Cydonia oblonga Mill) is a popular medicinal herb in different traditional medicines. Concentrated quince fruit extract, also known as quince sauce (QS), is traditionally used for the treatment of a variety of gastrointestinal disorders. The aim of this study was to compare the efficacy of QS versus ranitidine on gastroesophageal reflux disease (GERD) in pregnant women. We compared the efficacy of 4 weeks of ranitidine (150 mg, twice daily) with the efficacy of QS (10 mg, after meals) on 137 pregnant women with GERD. Their General Symptom Score (GSS) and Major Symptom Score (MSS) were compared at the baseline, 2 weeks and 4 weeks after intervention. After 2 weeks of the study, the mean GSS score of the QS group was significantly lower compared with the ranitidine group (p = .036). Although, the GSS value at the end of the study had no difference between groups (p = .074). However, the MSS of the different symptoms of the two groups at 2 weeks and 4 weeks had no significant differences. It seems that the efficacy of QS for the management of pregnancy-related GERD is similar to ranitidine. Impact statement What is already known on this subject? Quince is a traditional gastric tonic, an appetiser, and a remedy for nausea/vomiting and epigastric pain. Also, there are several previous positive experiences about quince products for GERD treatment. What do the results of this study add? It seems that the efficacy of QS for the management of pregnancy-related GERD is similar to ranitidine. What are the implications of these findings for clinical practice and/or further research? QS can be suggested as an alternative medicine for pregnant patients with GERD.

Abstract
BACKGROUND Elevated serum ferritin concentration is associated with insulin resistance and diabetes. Recently it has also been described in gestational diabetes mellitus (GDM). OBJECTIVE A prospective study was done to determine whether there was a relationship between serum ferritin concentration in early pregnancy and the risk of GDM. MATERIALS AND METHODS A study was performed on 1,384 pregnant women with gestational age of 12-16 weeks. A blood sample was obtained for measurement of ferritin in the first trimester. Diagnosis of GDM was done by 75 gr oral glucose tolerance test between 24-28 wk. RESULTS Women who developed GDM had a higher concentration of serum ferritin than women who did not develop GDM (p=0.01). A ferritin concentration of 45 ng/ml was calculated to be the 75th percentile for healthy pregnant women. Considering this level 32% in the GDM group and 25.2%of normal subjects exhibited high ferritin levels (p=0.01). The risk of GDM with these high levels of ferritin was 1.4-fold higher than that for subjects with lower concentrations. The Odds Ratio was 1.4 (95% CI= 1-1.87) (p=0.01). After adjusted for age Odds Ratio was 1.38 (95% CI=1.02-1.86) (p=0.03) and after adjustment for pre-pregnancy Body Mass index, the adjusted odds ratio was 1.31 (CI= 0.96-1.79) (p=0.08). After multivariable adjustment (age and body mass index), the adjusted odds ratio was 1.3 (0.95-1.8) (p=0.09). CONCLUSION High serum ferritin can be regarded as a significant risk factor for the development of gestational diabetes.

Abstract
BACKGROUND Vitamin D supplementation during pregnancy has been supposed to defend against adverse gestational outcomes. OBJECTIVE This randomized clinical trial study was conducted to assess the effects of 50,000 IU of vitamin D every two weeks supplementation on the incidence of gestational diabetes (GDM), gestational hypertension, preeclampsia and preterm labor, vitamin D status at term and neonatal outcomes contrasted with pregnant women that received 400 IU vitamin D daily. MATERIALS AND METHODS 500 women with gestational age 12-16 weeks and serum 25 hydroxy vitamin D (25 (OH) D ) less than 30 ng/ml randomly categorized in two groups. Group A received 400 IU vitamin D daily and group B 50,000 IU vitamin D every 2 weeks orally until delivery. Maternal and Neonatal outcomes were assessed in two groups. RESULTS The incidence of GDM in group B was significantly lower than group A (6.7% versus 13.4%) and odds ratio (95% Confidence interval) was 0.46 (0.24-0.87) (P=0.01). The mean ± SD level of 25 (OH) D at the time of delivery in mothers in group B was significantly higher than A (37.9 ± 19.8 versus 27.2 ± 18.8 ng/ml, respectively) (P=0.001). There were no differences in the incidence of preeclampsia, gestational hypertension, preterm labor, and low birth weight between two groups. The mean level of 25 (OH) D in cord blood of group B was significantly higher than group A (37.9 ± 18 versus 29.7 ± 19ng/ml, respectively). Anthropometric measures between neonates were not significantly different. CONCLUSION Our study showed 50,000 IU vitamin D every 2 weeks decreased the incidence of GDM.

Abstract
Low serum vitamin D levels are correlated with insulin resistance during pregnancy. We have assessed the effects of different doses of vitamin D on insulin resistance during pregnancy. A randomized clinical trial was done on 120 women with a gestational age of less than 12 weeks. The women were divided into three groups randomly. Group A received 200 IU vitamin D daily, group B 50,000 IU vitamin D monthly and group C 50,000 IU vitamin D every 2 weeks from 12 weeks of pregnancy until delivery. The serum levels of fasting blood sugar (FBS), insulin, calcium and 25-hydroxyvitamin D were measured before and after intervention. We used the homeostatic model assessment of insulin resistance (HOMA-IR) as a surrogate measure of insulin resistance. The mean ± standard deviation of serum 25-hydroxyvitamin D increased in group C from 7.3 ± 5.9 to 34.1 ± 11.5 ng/ml and in group B it increased from 7.3 ± 5.3 to 27.23 ± 10.7 ng/ml, but the level of vitamin D in group A increased from 8.3 ± 7.8 to 17.7 ± 9.3 ng/ml (p < 0.001). The mean differences of insulin and HOMA-IR before and after intervention in groups A and C were significant (p = 0.01, p = 0.02). This study has shown that supplementation of pregnant women with 50 000 IU vitamin D every 2 weeks improved insulin resistance significantly.

Abstract
Early diagnosis of GDM is necessary to reduce maternal and fetal morbidity and mortality. As all approaches to diagnosis of GDM are costly and difficult, we meant to find an appropriate and simple way to perform this test. One-thousand six-hundred and fifty-three pregnant women were screened for GDM at 24-28 weeks of gestation. Initial screening was done by a glucose challenge test with 50 g glucose. If the 1-h blood glucose level exceeded 130 mg/dl, then a 3-h oral glucose tolerance test (OGTT) with 100 g glucose was performed, and diagnosis was established according to ADA criteria. For determining which plasma glucose level is the best test for diagnosis of GDM, we used receiver operative characteristic cures (ROC) by plotting sensitivity versus one minus specificity at different times of plasma glucose levels in OGTT. In 732 pregnant women with a positive GCT, a 2-h plasma glucose level above 150 mg/dl was the most powerful test for detecting GDM, which revealed a sensitivity and specificity of 0.84 (0.81-0.86) and 0.94 (CI: 0.92-0.96), respectively. The results of this study suggest that 2-h 100 g OGTT could be an appropriate approach to diagnose GDM, which is cost-effective and could reduce laboratory workload.

Abstract
AIMS To determine whether Glo-3A, (formerly referred to as homologue of Glb1 or Glb1) antibodies are associated with islet autoimmunity (IA) in children at increased risk for type 1 diabetes (T1D) and to investigate their relation with environmental correlates of T1D. METHODS We selected a sample from the Diabetes Autoimmunity Study in the Young (DAISY), a prospective study of children at increased risk for T1D. Cases were positive for insulin, glutamic acid decarboxylase (GAD), or insulinoma-associated antigen-2 (IA-2) autoantibodies on two consecutive visits and either diagnosed with diabetes mellitus or still autoantibody positive when selected. Controls were from the same increased risk group, of similar age as the cases but negative for autoantibodies. Sera from 91 IA cases and 82 controls were analyzed in a blinded manner for immunoglobulin G (IgG) antibodies to Glo-3A by ELISA. RESULTS Adjusting for family history of T1D and human leukocyte antigen (HLA)-DR4 positivity, Glo-3A antibodies were not associated with IA case status (OR: 1.01, 95% CI: 0.99-1.03). Adjusting for age, family history of T1D, and HLA-DR4 positivity, Glo-3A antibody levels were inversely associated with breast-feeding duration (beta = -0.08, p = 0.001) and directly associated with current intake of foods containing gluten (beta = 0.24, p = 0.007) in IA cases but not in controls. Zonulin, a biomarker of gut permeability, was directly associated with Glo-3A antibody levels in cases (beta = 0.73, p = 0.003) but not in controls. CONCLUSION Differing correlates of Glo-3A antibodies in IA cases and controls suggest an underlying difference in mucosal immune response.

Abstract
AIM Adiponectin is an insulin sensitizing protein. Because gestational diabetes mellitus is associated with insulin resistance, we compared serum adiponectin levels in women with gestational diabetes mellitus and healthy pregnant women. STUDY DESIGN Twenty-nine women with gestational diabetes and 26 women with impaired glucose tolerance were compared with 27 normal pregnant women in control group. Controls were matched for gestational age, age and body mass index (BMI) before pregnancy with two other groups. At 28 weeks of gestation serum concentration of adiponectin, insulin and insulin resistance (calculated by the homeostasis model assessment) were measured in three groups. MAIN FINDINGS The serum adiponectin level in gestational diabetes (6379.31 + or - 1934.90 ng/ml), was significantly lower than the impaired glucose tolerance test (7384.61 + or - 1626.70 ng/ml) and control groups (7962.96 + or - 2667.20 ng/ml),(p = 0.02). Serum level of insulin and HOMA index in gestational diabetes were higher than the normal group (p > 0.05). In patients with gestational diabetes, there was a significant correlation between serum adiponectin level and BMI before pregnancy (r = -0.531, p = 0.013). Also, the correlation between maternal serum adiponectin levels and neonatal birth weight was not significant (r = -0.07, p value = 0.73). CONCLUSION Our data show that serum adiponectin level was significantly lower in gestational diabetes in comparison with healthy pregnant women.
