Prevalence of Gestational Diabetes Mellitus and Its Associated Risk Factors in Boo-Ali Hospital, Tehran

Does Second Trimester Maternal Serum Zonulin Level Predict Gestational Diabetes Mellitus?

Zonulin, a protein that regulates intestinal permeability, has attracted attention as a potential biomarker for GDM. Therefore, this study aims to investigate whether there are differences in zonulin levels between the GDM group and control groups, especially between those receiving different treatments (diet and insulin). Based on this idea, we included 90 patients with a gestational age between 24 and 28 weeks in our study. While GDM was not detected in 33 of these patients, as a result of OGTT, 57 patients were diagnosed with GDM and these patients were followed throughout their pregnancy. Gestational diabetes was diagnosed by an OGTT performed between 24 and 28 weeks of gestation according to American Diabetes Association (ADA) standards. During follow-up, GDM patients were divided into two groups according to whether they required insulin treatment. Plasma zonulin levels were determined using enzyme-linked immunosorbent assay (ELISA) techniques. The GDM group had significantly higher plasma zonulin levels than the control group (p < 0.005). According to our research, zonulin may be a non-invasive biomarker involved in the etiology of GDM. Large-scale research on this topic is still needed.

Prioritizing the Psychosocial Support Needs of Mothers with Gestational Diabetes: A Delphi Study

Background

Gestational diabetes is the most common medical complication in pregnancy, and the psychosocial health of women suffering from this condition affects their adherence to treatment and self-efficacy. However, since it is not possible to design interventions dealing with all of these needs, the aim of this study was to prioritize the psychosocial supportive needs of women with gestational diabetes.

Materials and Methods

This was a modified Delphi design study involving 22 experts who were selected using purposive and snowball sampling methods. The study was conducted between April 2021 and June 2021. First, the psychosocial needs of diabetic pregnant women were extracted through a qualitative study involving interviews with multidisciplinary specialists and diabetic pregnant mothers (22 participants) and a systematic review of reputable scientific databases. Throughout the two Delphi stages, the questionnaire was classified, quantified, and analyzed.

Results

Based on the results of this study, the following are the top priorities when addressing the psychosocial needs of mothers with gestational diabetes: paying attention to and identifying the mother's worries and anxiety, husband and family support for diabetic pregnant women, the inclusion of specialized nutrition counseling services in mothers' treatment plan, timely education of mothers about diabetes and its complications, and proper nutrition for diabetic mothers.

Conclusions

The priorities of the supportive needs obtained in this study can be used to design interventions aimed at promoting psychosocial health, reducing stress and anxiety, and improving medication adherence in women with gestational diabetes.

Obstetrical and neonatal outcomes of cardio-facio-cutaneous syndrome: Prenatal consequences of Ras/MAPK dysregulation

We systematically delineated the prenatal phenotype, and obstetrical and neonatal outcomes of the RASopathy cardio-facio-cutaneous (CFC) syndrome. A comprehensive, retrospective medical history survey was distributed to parents of children with confirmed CFC in collaboration with CFC International, Inc. Data were collected on CFC gene variant, maternal characteristics, pregnancy course, delivery, and neonatal outcomes with the support of medical records. We identified 43 individuals with pathogenic variants in BRAF (81%), MEK1 (14%), or MEK2 (5%) genes. The median age was 8.5 years. Hyperemesis gravidarum, gestational diabetes, gestational hypertension, and preeclampsia occurred in 5/43 (12%), 4/43 (9%), 3/43 (7%), and 3/43 (7%) of pregnancies, respectively. Second and third trimester ultrasound abnormalities included polyhydramnios, macrocephaly, macrosomia, and renal and cardiac abnormalities. Delivery occurred via spontaneous vaginal, operative vaginal, or cesarean delivery in 15/42 (36%), 7/42 (16%), and 20/42 (48%), respectively. Median gestational age at delivery was 37 weeks and median birth weight was 3501 grams. Germline pathogenic vaiants had mutiple congenital consequences including polyhydramnios, renal and cardiac abnormalities, macrosomia, and macrocephaly on second and third trimester ultrasound. Elevated rates of operative delivery and neonatal complications were also noted. Understanding and defining a prenatal phenotype may improve prenatal prognostic counseling and outcomes.

Perceived social support in pregnant women with gestational diabetes attending hospitals in western Iran compared to healthy controls and its relationship with perceived anxiety

Background/purpose

Due to the importance of social support in pregnant women, especially those with gestational diabetes that cause anxiety and stress in them and requires effective and enough attention, this study aims to assess perceived social support of pregnant women with gestational diabetes in western Iran compared to healthy controls and its relationship with their perceived anxiety.

Methods

This is a descriptive/analytical study with a cross-sectional design conducted on 180 pregnant women with gestational diabetes (n = 89) and without gestational diabetes (n = 91) referred to the obstetrics and gynecology clinics of two hospitals (Asalian and Shahid Rahimi) in Khorramabad, western Iran. Data collection tools were a demographic checklist, the Multidimensional Scale of Perceived Social Support (MSPSS), and the Beck Anxiety Inventory (BAI). Collected data were analyzed in SPSS v.20 software using chi square test, independent t-test, one-way ANOVA, and Pearson correlation test.

Results

The difference between the two groups was significant in terms of perceived support from family (p = 0.001), perceived support from friends (p = 0.006), and anxiety (p = 0.047). Pearson correlation test results showed a significant negative relationship between the scores of MSPSS and BAI in patients (r= -0.329, p = 0.001) and controls (r=-0.204, p = 0.006). There was a significant difference in the MSPSS score among diabetic women in terms of having fetal macrosomia (p = 0.005), occupation (p = 0.003), education (p = 0.001), and frequency of pregnancy (p = 0.010).

Conclusions

The perceived social support level is higher in diabetic pregnant women compared to healthy peers in western Iran. Improvement of social support from family and friends can reduce the anxiety of pregnant women with/without diabetes.

Vitamin D Status and Gestational Diabetes in Russian Pregnant Women in the Period between 2012 and 2021: A Nested Case-Control Study

Several meta-analyses found an association between low maternal serum 25-hydroxyvitamin D (25(OH)D) level and gestational diabetes mellitus (GDM). However, some of them reported significant heterogeneity. We examined the association of serum 25(OH)D concentration measured in the first and in the second halves of pregnancy with the development of GDM in Russian women surveyed in the periods of 2012−2014 and 2018−2021. We conducted a case−control study (including 318 pregnant women) nested on two previous studies. In 2012−2014, a total of 214 women (83 GDM and 131 controls) were enrolled before 15 weeks of gestation and maternal serum 25(OH)D concentrations were measured twice: at 8th−14th week of gestation and simultaneously with two-hour 75 g oral glucose tolerance test (OGTT) at 24th−32nd week of gestation. In the period of 2018−2021, 104 women (56 GDM and 48 controls) were included after OGTT and 25(OH)D concentrations were measured at 24th−32nd week of gestation. Median 25(OH)D levels were 20.0 [15.1−25.7] vs. 20.5 [14.5−27.5] ng/mL (p = 0.565) in GDM and control group in the first half of pregnancy and 25.3 [19.8−33.0] vs. 26.7 [20.8−36.8] ng/mL (p = 0.471) in the second half of pregnancy, respectively. The prevalence rates for vitamin D deficiency (25(OH)D levels < 20 ng/mL) were 49.4% and 45.8% (p = 0.608) in the first half of pregnancy and 26.2% vs. 22.1% (p = 0.516) in the second half of pregnancy in women who developed GDM and in women without GDM, respectively. The frequency of vitamin D supplements intake during pregnancy increased in 2018−2021 compared to 2012−2014 (p = 0.001). However, the third trimester 25(OH)D levels and prevalence of vitamin D deficiency (25.5 vs. 23.1, p = 0.744) did not differ in women examined in the periods of 2012−2014 and 2018−2021. To conclude, there was no association between gestational diabetes risk and maternal 25(OH)D measured both in the first and in the second halves of pregnancy. The increased prevalence of vitamin D supplements intake during pregnancy by 2018−2021 did not lead to higher levels of 25(OH)D.
