Maternal Pathologies Associated with Admission to the Intensive Care Unit

Introduction: Maternal health is a global concern due to its significant impact on mothers and newborns. In developing countries, obstetric complications often lead to ICU admissions.Objective: To determine the prevalence of maternal pathologies associated with admission to the Intensive Care Unit (ICU) at the Instituto Ecuatoriano de Seguridad Social (IESS) in Manta, during the period from August 2022 to August 2023.Methods: A descriptive cross-sectional study was conducted with 13 patients admitted to the ICU for maternal pathologies. Variables analyzed included age, type of delivery, maternal pathology, and length of hospital stay.Results: Women aged 25 to 30 years represented 30.77% of ICU admissions. 76.92% of deliveries were by cesarean section. The main pathologies identified were severe preeclampsia (31.03%) and sepsis (20.69%). The duration of hospital stay ranged from three to five days in most cases.Conclusions: Adolescent women and those aged 25 to 30 are most likely to require intensive care. Severe preeclampsia and sepsis are the primary causes of ICU admission.

Placenta Extracellular Vesicles: Messengers Connecting Maternal and Fetal Systems.

The placenta operates during gestation as the primary communication organ between the mother and fetus. It is essential for gas, nutrient exchange, and fetal waste transfer. The placenta also produces a wide range of hormones and other factors that influence maternal physiology, including survival and activity of the corpus luteum of the ovary, but the means whereby the placenta shapes fetal development remain less clear, although the fetal brain is thought to be dependent upon the placenta for factors that play roles in its early differentiation and growth, giving rise to the term "placenta-brain axis". Placental hormones transit via the maternal and fetal vasculature, but smaller placental molecules require protection from fetal and maternal metabolism. Such biomolecules include small RNA, mRNA, peptides, lipids, and catecholamines that include serotonin and dopamine. These compounds presumably shuttle to maternal and fetal systems via protective extracellular vesicles (EVs). Placental EVs (pEVs) and their components, in particular miRNA (miRs), are known to play important roles in regulating maternal systems, such as immune, cardiovascular, and reproductive functions. A scant amount is known about how pEVs affect fetal cells and tissues. The composition of pEVs can be influenced by gestational diseases. This review will provide critical insight into the roles of pEVs as the intermediary link between maternal and fetal systems, the impact of maternal pathologies on pEV cargo contents, and how an understanding of biomolecular changes within pEVs in health and disease might be utilized to design early diagnostic and mitigation strategies to prevent gestational diseases and later offspring disorders.

A case of severe combined pathology in a late premature infant with hypoxic-ischemic damage to the central nervous system

A clinical observation of severe combined pathology in a late premature infant with hypoxic-ischemic damage to the central nervous system is presented. The extremely unfavorable effect of maternal pathology, in particular diabetes mellitus, on the intrauterine condition of the fetus has been demonstrated, which led to the birth of a premature baby, with the subsequent development of hypoxic-ischemic damage to the central nervous system, intraventricular non-traumatic hemorrhages, diabetic fetopathy, hyperbilirubinemia and the implementation of the infectious process. This case demonstrates that a late premature infant has a combined pathology, which is the basis for using a multidisciplinary approach in their management. Despite the fact that late premature newborns at the time of birth have anthropometric data comparable to full-term ones, they have higher morbidity rates in the early neonatal period. Neonatologists must be wary of this group of children in order to timely determine the scope of the complex of therapeutic measures.

Embryos from Prepubertal Hyperglycemic Female Mice Respond Differentially to Oxygen Tension In Vitro.

Reduced oxygen during embryo culture in human ART prevents embryo oxidative stress. Oxidative stress is also the major mechanism by which maternal diabetes impairs embryonic development. This study employed induced hyperglycemia prepubertal mice to mimic childhood diabetes to understand the effects of varying oxygen tension during in vitro embryonic development. The oocytes were fertilized and cultured at low (≈5%) oxygen (LOT) or atmospheric (≈20%) oxygen tension (HOT) for up to 96 h. Embryo development, apoptosis in blastocysts, inner cell mass (ICM) outgrowth proliferation, and Hif1α expression were assessed. Though the oocyte quality and meiotic spindle were not affected, the fertilization rate (94.86 ± 1.18 vs. 85.17 ± 2.81), blastocyst rate (80.92 ± 2.92 vs. 69.32 ± 2.54), and ICM proliferation ability (51.04 ± 9.22 vs. 17.08 ± 3.05) of the hyperglycemic embryos were significantly higher in the LOT compared to the HOT group. On the other hand, blastocysts from the hyperglycemic group, cultured at HOT, had a 1.5-fold increase in apoptotic cells compared to the control and lower Hif1α transcripts in ICM outgrowths compared to the LOT. Increased susceptibility of embryos from hyperglycemic mice to higher oxygen tension warrants the need to individualize the conditions for embryo culture systems in ART clinics, particularly when an endogenous maternal pathology affects the ovarian environment.

A newborn Screening Programme for Inborn errors of metabolism in Galicia: 22 years of evaluation and follow-up

BackgroundThere is a notable lack of harmonisation in newborn screening (NBS) programmes worldwide. The Galician programme for early detection of inborn errors of metabolism (IEM) was one of the first NBS programmes in Europe to incorporate mass spectrometry (July 2000). This programme currently screens for 26 IEMs in dried blood and urine samples collected 24–72 h after birth.ResultsIn its 22-year history, this programme has analysed samples from 440,723 neonates and identified 326 cases of IEM with a prevalence of 1:1351. The most prevalent IEMs were hyperphenylalaninaemia (n = 118), followed by medium chain acyl-CoA dehydrogenase deficiency (MCADD, n = 26), galactosaemia (n = 20), and cystinurias (n = 43). Sixty-one false positives and 18 conditions related to maternal pathologies were detected. Urine samples have been identified as a useful secondary sample to reduce the rate of false positives and identify new defects. There were 5 false negatives. The overall positive value was 84.23%. The fatality rate over a median of 12.1 years of follow-up was 2.76%. The intelligence quotient of patients was normal in 95.7% of cases, and school performance was largely optimal, with pedagogic special needs assistance required in < 10% of cases. Clinical onset of disease preceded diagnosis in 4% of cases. The age at which first NBS report is performed was reduced by 4 days since 2021.ConclusionsThis study highlights the benefits of collecting urine samples, reduce NBS reporting time and expanding the number of IEMs included in NBS programmes.

Preterm birth and stillbirth during COVID-19 pandemic in Bihor County/Romania.

International studies have reported conflicting data about the effects of COVID-19 pandemic policy measures on maternal and neonatal health. A major impact was reported on stillbirth and prematurity. The published literature suggests that the economic setting influenced the effects of imposed mitigation measures with a more severe effect in low-income countries. Our objective is to compare pregnancy outcomes at the only tertiary Maternity Hospital in Bihor County-Romania before and during the COVID-19 pandemic. This study aims to observe and document differences in perinatal outcomes across these periods, without inferring direct causation related to the pandemic or its associated restrictions. We used data from the registries of Public Health Services Bihor to conduct a retrospective cohort analysis of preterm births and stillbirths during the COVID-19 pandemic in Bihor County, Romania. Pregnancy outcomes were compared between the pandemic period (March 2020-February 2022) to the corresponding historical pre-COVID-19 period (March 2018-February 2020). Maternal socio-demographic variables and neonatal characteristics of these periods were also examined. The COVID-19 pandemic period was associated with an increase in the stillbirth rate (RR: 1.53, 95% CI, 1.05-2.23). Preterm birth was significantly impacted during this period and showed changes when analyzing gestational age (RR: 0.88, 95% CI, 0.79-0.96) or birth weight (RR: 0.91, 95% CI, 0.82-1.00). The main cause of stillbirth was intrauterine asphyxia due to placental causes (67.6%) or cord pathology (12.6%), the most frequently encountered maternal pathology was cardiovascular (28.3%) or infectious (21.7%). Our study revealed no significant changes in terms of maternal and neonatal characteristics during the two-year pandemic period. Lockdown restrictions in Bihor County, Romania were associated with an increase in stillbirths, whilst preterm birth rate decreased. This raises concerns about whether pandemic policy measures may have led to a failure in identifying and offering proper care for pregnant women who were more likely to experience an antepartum loss. Further studies across the globe are needed in order to integrate comparable data that will help develop adequate protocols and policies for protecting maternal and child health during the next pandemic that will follow.

Prenatal diagnosis of Fetal Cardiac Rhabdomyoma associated with Familial Tuberous Sclerosis

Introduction: Of the fetal heart tumors, the most common are rhabdomyomas. Its prevalence is based on 11,000 autopsies performed on children and is 0.027%.1 Its diagnosis in the prenatal stage is a challenge, however, it has been reported in the second and third trimesters of gestation.Clinical case: 19-year-old female patient with a history of presenting with lipothymia at 2 years of age. Given these manifestations, she underwent different studies, including Cranial Magnetic Resonance (MRI), which concluded as a diagnosis of Tuberous Sclerosis. In its current state of gestation, at week 33, a finding is seen that corresponds to unilateral pulmonary agenesis; at 35 weeks, liver and kidney ultrasounds are performed on the mother and fetal ultrasound. Serial ultrasound findings revealed maternal hepatic and renal hemangiolipoma. Fetal biventicular rhabdomyoma with probable transposition of the great vessels and pulmonary artery stenosis.Discussion: Rhabdomyomas are the most common fetal cardiac tumors. In our clinical case, the pregnant woman had a history of Bourneville Tuberous Sclerosis. The definitive diagnosis of maternal pathologies was made in the 3rd trimester. It was complicated to manage due to suspicion of additional heart disease of the Classical Transposition of the Great Vessels type, evidenced by imaging studies. He was subsequently referred to a more complex center for better follow-up and definitive treatment.Conclusions: Fetal rhabdomyoma diagnosed prenatally is complex, requiring serial imaging studies and multidisciplinary follow-up. It is important to monitor the hemodynamic status and any cardiovascular repercussions of the pregnant woman. In addition, fetal structures including the central nervous system, heart and renal parenchyma must be carefully evaluated to avoid significant sequelae in those affected.

Características de los casos de óbito fetal en un hospital público de Perú: estudio descriptivo

Objective: To describe the characteristics of fetal death cases reported between 2017 and 2021 in a public hospital in Peru. Methods: Descriptive and cross-sectional study, which was conducted in confirmed cases of fetal death in mothers with gestational age greater than 22 weeks presented at the Vitarte Hospital in Lima, Peru. The sample consisted of 137 cases during the period from 2017 to 2021. Frequencies and percentages were presented. Results: Fetal death had a rate of 14,8 per 1000 live births. Most of the women were between 20 and 24 years old (27%), in addition, 70,1% were cohabiting, 92% were housewives and 83,2% studied up to high school. On the other hand, 50,4% were multigestational and 29,9% had a history of abortion and 16,7% had a history of cesarean section. Prenatal service attendance was the most frequent (67,2%) and 29,2% were overweight. Regarding maternal pathologies, 38% had urinary tract infection, 17,5% had preeclampsia without signs of safety and 2,9% had gestational diabetes. Congenital malformations were present in 19% of cases; in addition, 23,4% of fetal deaths had a maternal cause. Conclusions: The rate of fetal death is high. The cases were characterized mostly by mothers with qualities of social vulnerability, in addition to presenting characteristics of higher obstetric risk. Maternal causes of fetal death were the most frequent. Keywords: Fetal death, pregnancy, delivery, risk factors.

Pregnancy-Associated Cancer: A Case Report of a Gastric Cancer Diagnosis in the III Trimester of Pregnancy and Subsequent Management

The co-occurrence of gastric carcinoma and pregnancy is very rare event. Diagnosis is often delayed, frequently at an advanced stage due to the nonspecific symptomatology, which can be confused with the normal physiological symptoms of pregnancy. Therefore, a multidisciplinary approach is essential to initiate the treatment of maternal pathology as early as possible, with the goal of delivering at a moderately preterm gestation age to ensure favorable neonatal outcome. We present a case of gastric carcinoma diagnosed during the third trimester, where the earliest presentation included liver metastases, and the primary tumor’s location was unknown. Throughout our observation period, we conduced clinical-laboratory monitoring, a preliminary radiological staging of the illness (considering the limitations imposed by pregnancy), and a histological diagnosis with biopsy sampling. An elective cesarean section was performed in the moderately preterm period, following the completion of Respiratory Distress Syndrome (RDS) prophylaxis.

Algerian postcaesarean surgical site infections: A cross-sectional investigation of the epidemiology, bacteriology, and antibiotic resistance profile

Surgical site infections (SSIs) are one of the most common health care-associated infections in low and middle-income countries. The aims of this cross-sectional descriptive study were to estimate the frequency of postcaesarean infection with associated clinical characteristics and the antibiotic resistance profile of bacterial isolates. Patients who underwent a cesarean section at the obstetrics and gynecology department of the hospital in Annaba, Algeria were included. Each woman was followed postoperatively for 30 days and sociodemographic data were collected. Culture-based microbiological methods were used to identify the causative bacteria and determine their antibiotic resistance phenotype and molecular characterization. Among 1,810 patients, we recorded 36 (1.9%) SSIs. Most patients had undergone an emergency delivery (75%) and low educational level (72.2%). The most frequent maternal pathologies were Body Mass Index≥30 (63.9%), scarred uteri (58.3%), anemia (55.6%), and an American Society of Anaesthesiologists score between II and III (33.3%). Of the 43 bacteria isolated, Enterobacteriaceae were the most frequent (62.8%), predominated by Escherichia coli strains (43.5%), a majority of which were extended-spectrum β-lactamases carriers (62.9%). Although gram-positive cocci were less frequent (37.2%), a majority of Enterococcus faecalis (56.2%) were observed and 2 strains of vancomycin-resistant Enterococcus faecium harboring the vanA gene were identified. Extensive surveillance of at-risk populations should be integrated to prevent the occurrence of SSIs.

Placenta as an important component of the «mother-placenta-fetus» medical-biological system: A literature review

Relevance: To date, there is no single approach between clinicians and morphologists in assessing the role of placental insufficiency in the development of fetal and maternal pathology. This situation is due, firstly, to the complexity of the histological assessment of the degree of compensatory reaction of placental tissue, and secondly, to the assessment of the degree of its maturity and the level of circulatory disorders that affect the features of intrauterine development of the child.The study aimed to review the placenta examination as an essential component of objective diagnostics to identify prenatal risks for the baby.Materials and Methods: A comprehensive search was performed in the databases e-Library, Pubmed, Web of Science, Scopus, and Embase to identify relevant articles on the topic published over the past decade. A total of 78 publications were analyzed, of which 47 articles corresponded to the purpose of the study.Results: By the nature of the structural state of the placenta, it is possible to diagnose vascular and dystrophic changes and verify inflammatory processes of nonspecific and specific genesis. Since the placenta serves as a mirror image of the infectious pathology of the mother, their children are at risk of infection.Conclusion: Thus, the assessment of the nature of morphological changes in the placenta, both in the relatively physiological course of pregnancy and the presence of pathology of pregnancy and childbirth, with somatic or infectious pathology of the mother, makes it possible to make a prognosis about the condition of the child, both during intrauterine development, and to give a prognostic assessment during the newborn and postnatal period.

Fetal Pulmonary Venous Return: From Basic Research to the Clinical Value of Doppler Assessment.

The fetal pulmonary circulation represents less than 25% of the fetal cardiac output. In comparison with the pulmonary arteries, studies on pulmonary veins are few and limited, and many questions remain to be answered. The literature reports that pulmonary veins play an important role in regulating vascular flow, forming an active segment of the pulmonary circulation. The development of more sophisticated ultrasonography technology has allowed the investigation of the extraparenchymal pulmonary veins and their waveform. The recognition of the pulmonary vein anatomy in echocardiography is important for the diagnosis of anomalous pulmonary venous connections, with a significant impact on prognosis. On the other hand, the identification of the normal pulmonary vein waveform seems to be a reliable way to study left heart function, with potential applicability in fetal and maternal pathology. Thus, the goal of this narrative review was to provide a clinically oriented perspective of the available literature on this topic.

Epidemioclinical and Therapeutic Study of Caesarean Sections at the Markala Reference Health Centre

This was a retrospective study conducted at the Markala referral health centre from 2019 to 2022. The general objective was to study caesarean section at CS Réf in Markala. During our study period from 2019 to 2022, we recorded 1244 caesarean sections, i.e. a frequency of 28.29% of all deliveries. Parturients were evacuated in 51.6% of cases. Only 14.23% of our parturients were well monitored. The most frequent indication for caesarean section was SFA in 30.1%, i.e. 375 cases. The surgical procedure most frequently associated with caesarean section was LRT. Maternal mortality was 0.3%, mainly due to haemorrhage and pregnancy-related maternal pathologies. Maternal morbidity was dominated by infections, severe anaemia and haemorrhage. Fetal mortality was 11.9%, mainly due to severe fetal distress. Resuscitation was required for 23.5% of our caesarean section babies. Improving these results requires the support of all sectors of society.

Antenatal risk factors for retinopathy of premature

This literature review presents the antenatal risk factors for the development of retinopathy of prematurity (ROP). Despite advances in antenatal and neonatal therapeutic interventions, screening, and follow-up, ROP remains a potentially vision-threatening retinopathy that requires careful monitoring and timely intervention to prevent the progression of adverse visual impairment or blindness. ROP is a multifactorial disease. The main risk factors are low gestational age and low birth weight. Recent experimental and clinical data support the hypothesis that multiple antenatal factors are involved in the etiology and progression of ROP. These factors include the age of the mother, maternal diseases, pregnancy-associated maternal pathologies, use of drugs to correct these conditions, and inflammatory process. Their roles are ambiguous and often contradictory. The physiology of the mother and placenta can significantly influence the risk of ROP development in preterm infants. The placenta connects the mothers body and the fetus, and it functions in the exchange of nutrients and oxygen between the mother and the fetus. Therefore, any pathological changes in the mothers body entail changes in the placenta, which this directly affects the fetus. A sudden loss of placental support is detrimental to the development of infants in the immediate postnatal period. Thus, these factors should be taken into account when assessing the risk of ROP development to predict and prevent poor vision in children.

Analysis of congenital pneumonia incidence in newborns from high-risk mothers

Objective. To detect the incidence of congenital pneumonia in newborns from mothers with placental insufficiency in combination with premature amniotic fluid discharge&#x0D; Materials and methods. A retrospective analysis of 57 stories of newborn infants and their mothers was carried out. The newborns were divided into 3 groups: group 1 37 newborns from mothers with placental insufficiency and premature amniotic fluid discharge, group 2 9 infants from mothers with premature amniotic fluid discharge, group 3 11 infants born from mothers with placental insufficiency. The obstetric and gynecological history, the presence of extragenital pathology, the peculiarities of the course of pregnancy and childbirth, and the outcomes for newborns were analyzed.&#x0D; Results. Congenital pneumonia was more common in newborns from mothers with placental insufficiency and premature amniotic fluid discharge. In newborn infants of the first group, severe asphyxia occurred more often, being a risk factor. At the same time, the identification of markers of the systemic inflammatory reaction did not always reflect the presence of infectious-inflammatory pathology in newborns. In addition, in the presence of inflammation of the fetal part of placenta, in a large number of newborns pathological microflora is detected during microbiological examination.&#x0D; Conclusions. As a result of the study, the role of maternal pathology on the development of intrauterine infection and implementation of infection in the early neonatal period was revealed. The obtained data justify the need for pregravid preparation and prevention of perinatal complications in women with placental insufficiency.

Determinants of Neonatal Morbidity And Mortality In The Suburbs of Dakar in Senegal

Introduction: Neonatal morbidity and mortality is a major public health problem in developing countries such as Senegal. The objective of our study was to study the determinants of neonatal morbidity and mortality in a hospital located in the suburbs of Dakar in Senegal. Materials and methods: We conducted a retrospective, descriptive and analytical study over the period from 1 January to 31 December 2019 (1 year). Results: Of the 1198 children hospitalized in the ward, all 500 were newborns. (incidence=41.7%). The sex ratio was 1.29. The most common maternal pathologies were hypertension, preeclampsia and diabetes. The notion of urogenital infection was reported in 21% of cases MPR was greater than 12 hours in 60% of cases. More than a quarter (27%) of newborns had not screamed at birth and 74% were resuscitated. Almost half of newborns (43%) were preterm infants. Hypotrophs accounted for 48% (n=202). Diagnoses on admission were dominated by infections neonatal, inhalation of amniotic fluid, hyaline membrane disease and perinatal asphyxia. The mortality rate was 19% (n=95). The most frequently found causes of death were related to prematurity (48.4%), respiratory distress (82%) and nosocomial infections (20%). Conclusion: Despite initiatives undertaken at the national level, statistics remain alarming and call for more efforts to be made to achieve the Sustainable Development Goals (SDGs) by 2030.

Does time heal all wounds? How is children's exposure to intimate partner violence related to their current internalizing symptoms?

The effects of time and the longitudinal course of the children's internalizing symptoms following Intimate Partner Violence Exposure (IPVE) are still of great interest today. This study aimed to analyze the effect of the frequency of IPVE, adverse experiences after the cessation of the IPVE and the time elapsed since the termination of the violent relation on the prevalence of anxiety and depression among children. Participants were 107 children and their mothers who had been victims of IPV and had existing judicial protection and restraining orders. Hierarchical logistic regression models were estimated to analyze children's adjustment, considering the effect of the time elapsed since the termination, frequency of IPVE, experiences of revictimization, maternal pathology, and anxious anticipation of the mother at the prospect of future harm. Exposure to multiple events of violence at the hands of multiple ex-partners and higher scores in the mother's anxious anticipation were significant predictors of children's pathological depression and anxiety. Our results emphasize the need for early psychological evaluation of women and children's victims of IPV to provide timely interventions that avoid symptoms from becoming chronic. Strategies to bring support and emotional security to the victims after the end of the violent relationship are desirable.

The Insight into Obstetric Care near the Front Line in Kharkiv.

The invasion of Russian troops into independent Ukraine has changed the humanitarian situation in the Kharkiv region. The paper is focused on the peculiarities and issues of the management of labor and delivery near the front line. Totally 2030 patients were enrolled in the study. 1410 women who delivered in the second half of 2021 were enrolled in Group I. 620 women who delivered in the first half of 2022 were observed in Group II. Some patients from Group II were used for the investigation of the comparative situation during first months of 2022. 85 women who delivered in January were included in Subgroup IIA. 94 women who have completed their pregnancies and delivered in February were observed in Subgroup IIB. 67 case histories of deliveries which occurred during March were united in Subgroup IIC. The level of anemia, uterine contractile activity in labor abnormalities, and episiotomies were surprisingly lower during wartime in March. The obtained results showed an almost similar level of obstetric complications, maternal comorbidities, and interventions during labor and delivery in all groups. The stressed environment was a possible reason for the elevation of cardiovascular disease and endocrine disorders. The study did not reveal any significant changes in the structure of maternal pathologies and obstetric complications during the first months of wartime near the front line. But later the levels of cardiovascular disease and endocrine disorders were found to be elevated.

Relação entre a educação pré-natal para o aleitamento materno e a técnica de amamentação

Abstract Objectives: compare the evaluation of breastfeeding technique between binomials who did or did not receive prenatal education orientation. Methods: original study based on the application of breastfeeding evaluation form on binomials in joint accommodation (JA) composing of twenty (20) Yes/No questions and the collection of bi categorized independent variables between August/2017-October/2018. Prenatal educational activities with nominal listing of those present and thus creation of the variable was: Prenatal Class Yes/No. Multivariate analysis by Logistic regression were performed with confdence interval at 95%. Results: 180 binomials were included, of which 13 (7%) were exposed to prenatal activities and 167 (93%) were not exposed. In the exposed group, there was a predominance of married and multiparous women (p&lt;0.05), in addition to lower educational level and higher rate of maternal pathologies and low birth weight (p&lt;0.05). Regarding the breastfeeding evaluation, of the 20 questions observed, the exposed group was superior in 12 of them. Among the 4 questions about the Newborn’s grip, the exposed group was superior in 3 (baby’s mouth wide open, lip lowered and chin touching the breast), and the unexposed group was superior in the areola visualization above the upper lip with p&lt;0.05. The limitation found in the study was attributed to quantitative and qualitative heterogeneity between groups. Conclusions: prenatal education for breastfeeding did not alternate significantly the performance of binomials on the breastfeeding technique in this study.

Pathophysiological Role of Genetic Factors Associated With Gestational Diabetes Mellitus

Gestational Diabetes Mellitus (GDM) is a highly prevalent maternal pathology characterized by maternal glucose intolerance during pregnancy that is, associated with severe complications for both mother and offspring. Several risk factors have been related to GDM; one of the most important among them is genetic predisposition. Numerous single nucleotide polymorphisms (SNPs) in genes that act at different levels on various tissues, could cause changes in the expression levels and activity of proteins, which result in glucose and insulin metabolism dysfunction. In this review, we describe various SNPs; which according to literature, increase the risk of developing GDM. These SNPs include: (1) those associated with transcription factors that regulate insulin production and excretion, such as rs7903146 (TCF7L2) and rs5015480 (HHEX); (2) others that cause a decrease in protective hormones against insulin resistance such as rs2241766 (ADIPOQ) and rs6257 (SHBG); (3) SNPs that cause modifications in membrane proteins, generating dysfunction in insulin signaling or cell transport in the case of rs5443 (GNB3) and rs2237892 (KCNQ1); (4) those associated with enzymes such as rs225014 (DIO2) and rs9939609 (FTO) which cause an impaired metabolism, resulting in an insulin resistance state; and (5) other polymorphisms, those are associated with growth factors such as rs2146323 (VEGFA) and rs755622 (MIF) which could cause changes in the expression levels of these proteins, producing endothelial dysfunction and an increase of pro-inflammatory cytokines, characteristic on GDM. While the pathophysiological mechanism is unclear, this review describes various potential effects of these polymorphisms on the predisposition to develop GDM.
