PCOS and vitamin D: a clinical appraisal.

PURPOSE: Polycystic ovary syndrome (PCOS) is the most common endocrine-reproductive disease linked not just to infertility but also to serious comorbidities. There is a reported association between low vitamin D levels and multiple health conditions including PCOS. This narrative review aims to analyze the role of vitamin D in PCOS development, use of the vitamin D in the treatment of PCOS, and the molecular basis of these observations. METHODS: A Medline and PubMed research was performed, during the years 1990-2023, using a combination of keywords on such topic. According to the author's evaluation and target, papers were identified and included for a narrative review. RESULTS: There are associations between lower levels of vitamin D and PCOS, as well as with insulin resistance, metabolic syndrome, hyperandrogenemia, metabolic and endocrine disorders as well as the onset of oxidative stress and pro-inflammatory milieu, in PCOS women. CONCLUSION: Vitamin D has a role in pathologic changes linked to PCOS. Molecular and clinical investigations which give new information about the role of vitamin D in the development of PCOS and related endocrine and metabolic disturbance are further needed.

Reflections on Postpartum Hysterectomy as a Possible Complication of Cesarean Myomectomy: A Long Debate.

Uterine fibroids are common benign tumors found in fertile women. Numerous obstetrical issues, such as dystocia during labor, fetal hypotrophy, a ruptured amniotic sac, early labor, low-birth-weight newborns, etc., are associated with fibrous pregnant uteri. Cesarean myomectomy is not a common procedure because of the possibility of postpartum hysterectomy or a potentially lethal hemorrhage. For the chosen topic, we present two instances of emergency postpartum hysterectomies following cesarean myomectomy. After a cesarean myomectomy, two women experienced a perioperative hemorrhage that required a postpartum hysterectomy without a salpingo-oophorectomy. A postpartum hysterectomy was required in every instance due to the failure of additional hemostatic techniques to control the bleeding after the cesarean myomectomy. In every case, the location and number of fibroids-rather than their size-were the primary factors leading to the postpartum hysterectomy. In order to ensure that the patient is safe and that the advantages outweigh the dangers, the current trends in cesarean myomectomy include aiming to conduct the procedure either electively or when it offers an opportunity. The treatment is still up for debate because it is unknown how dangerous a second hysterectomy is for people who have had a cesarean myomectomy.

Cesarean Myomectomy: Reflections on Clinical and Surgical Controversies between a New Trans-Decidual Technique vs. Traditional Method.

Up to 70-80% of women of reproductive age may be affected with the most common uterine tumors, known as fibroids or myomas. These benign tumors are the second most prevalent cause of surgery among premenopausal women. Predictions show that the occurrence of myomas in pregnancy will increase, and that the risk of having myomas during pregnancy increases with advanced maternal age. Although most women with fibroids do not experience any symptoms during pregnancy, up to 30% of women experience problems during pregnancy, childbirth, and the puerperium. The viability of myoma excision during cesarean surgery (CS) is a contentious issue raised by the rising incidence of myomas in pregnancy and CS rates. A new surgical procedure for removing fibroids using a trans-endometrial approach, which involves making an incision through the decidua itself, has put into doubt the long-standing practice of cesarean myomectomy (CM) with a trans-serosal approach. Some authors have recently advocated for this last approach, highlighting its advantages and potential uses in real-world situations. The purpose of this paper is to critique the present approach to cesarean myomectomy by analyzing the clinical and surgical distinctions between the two approaches and providing illustrations of the CM methods.

Myomectomy in adult women of reproductive age: a propensity score-matched study for pregnancy rates.

PURPOSE: To study whether it is better to perform or not a myomectomy, in terms of surgical and reproductive outcomes in patients of advanced reproductive age, by an observational prospective study in university-affiliated and Community Hospitals. MATERIALS AND METHODS: 40 years and older patients affected by non-submucous symptomatic uterine fibroids and desiring future fertility were enrolled and treated by laparoscopic intracapsular myomectomy by (LIM) or by open laparotomy (OIM), or by a non-surgical management as control group, while attempting to conceive. The primary outcome measures were fibroid characteristics, pre- and post-surgical parameters, pregnancy achievement; the secondary outcome measures were the spontaneous or ART pregnancy outcomes, eventual week of abortion and type of delivery. Propensity scores have been calculated with logistic regression for binary and continuous variables. RESULTS: 202 patients completed the study: 112 operated by LIM, 40 by OIM and 50 patients as control group. Patients undergoing OIM have a worse surgical outcome than LIM. No difference was seen in pregnancy either after myomectomy or control group during follow-up. In the LIM group, there were 44 pregnancies (39.2%), and in the OIM group, there were 9 (22.5%) and 16 in the control group (32%). The weeks of delivery were statistically greater for the control group versus the surgical groups, with no difference in Apgar score between the 3 groups. CONCLUSION: Patients aged over 40 years did not show substantial differences in reproductive outcome, whether operated or not. Myomectomy in over 40-year-old patients has no detrimental effect on future pregnancy rates and over when compared to expectant management.

Uterine Aging and Reproduction: Dealing with a Puzzle Biologic Topic.

Uterine aging is the process of the senescence of uterine tissue, observed in all middle-aged mammals. Since the aging-related changes in the uterus are associated with infertility and poor pregnancy outcomes, with a lack of studies discussing uterine aging, authors reviewed uterine aging and its consequences on reproduction. MEDLINE, Scopus, and PubMed searches during the years 1990-2023 were performed using a combination of keywords and terms on such topics. According to the author's evaluation, articles were identified, selected, and included in this narrative review. The aging process has an unfavorable impact on the uterus of mammals. There are different and selected molecular pathways related to uterine aging in humans and animals. Uterine aging impairs the function of the uterine myometrium, neurofibers of the human uterus, and human endometrium. These biological pathways modulate oxidative stress, anti-inflammatory response, inflammation, mitochondrial function, DNA damage repair, etc. All these dysregulations have a role in poorer reproductive performance and pregnancy outcomes in older mammals. The most recent data suggest that uterine aging is accompanied by genetic, epigenetic, metabolic, and immunological changes. Uterine aging has a negative impact on the reproductive performance in mammalian species, but it could be potentially modulated by pharmacological agents, such as quercetin and dasatinib.

Molecular Insights in Uterine Leiomyosarcoma: A Systematic Review.

Uterine fibroids (UFs) are the most common benign tumors of female genital diseases, unlike uterine leiomyosarcoma (LMS), a rare and aggressive uterine cancer. This narrative review aims to discuss the biology and diagnosis of LMS and, at the same time, their differential diagnosis, in order to distinguish the biological and molecular origins. The authors performed a Medline and PubMed search for the years 1990-2022 using a combination of keywords on the topics to highlight the many genes and proteins involved in the pathogenesis of LMS. The mutation of these genes, in addition to the altered expression and functions of their enzymes, are potentially biomarkers of uterine LMS. Thus, the use of this molecular and protein information could favor differential diagnosis and personalized therapy based on the molecular characteristics of LMS tissue, leading to timely diagnoses and potential better outcomes for patients.

Long-term quality of life assessment after excisional treatment for cervical dysplasia.

We evaluated factors influencing long-term health-related quality of life (HRQoL) after excisional treatments of low- and high grade squamous intraepithelial cervical lesions (SIL) in three groups of women (n = 160): nulliparas interested in reproduction (A), parous women interested in reproduction (B) and women without pregnancy desire (C). The HRQoL was assessed using the disease-specific FACIT-CD and the generic SF36v2 questionnaires. Anxiety and depression were evaluated by Beck's inventories. After median follow-up of 5 (2-18) years, FACIT-CD total score and the score for Emotional Well-Being (EWB) were significantly lower in group A. The total, EWB and REL (Relationships) scores of FACIT-CD were the highest in group B. Women operated for HSIL demonstrated lower REL quality in comparison to those with LSIL. Neither SF36v2 nor FACIT-CD total scores differed in relation to SIL grade or type of excision. 'SF36v2 Mental Component Summary Score' and 'being parous and interested in fertility' were independent predictors of disease-specific FACIT-CD score.Impact StatementWhat is already known on this subject? Long-term consequences of excisional treatments for cervical dysplasia on health-related quality of life (HRQoL) are not well reported.What do the results of this study add? Our study provides data on HRQoL in women treated with large loop excision of the transformation zone (LLETZ) or cold knife conization (CKC) obtained during the longest (median 5 years) follow-up as reported to date. We were able to show that having children and planning further pregnancies positively influenced HRQoL in these patients. In addition, we identified nulliparas with pregnancy desire as psychologically the most vulnerable group within the studied cohort.What are the implications of these findings for clinical practice and/or further research? Even several years after LLETZ or CKC, women may suffer from impaired Emotional Well-Being and reduced HRQoL. Awareness and assessment of these long-term consequences should be part of surveillance after excisional treatments for cervical dysplasia.

Do Changes in Body Shape Due to Pregnancy Lead to Cosmetic Surgery? A Cross-Sectional Study.

OBJECTIVE: Pregnants and puerperas show different perceptions of their body image and appearance, so authors investigated their perceptions related to pregnancy and puerperium, evaluating their views on cosmetic surgery, by a cross-sectional study. MATERIALS AND METHODS: 5-item questionnaires were administrated to women at first pregnancy and puerperas. Patients were submitted also to Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI) and Body Image Inventory (BII) analysis, indicating the level of anxiety, depression and body dissatisfaction for somatic changes during pregnancy and after childbirth. RESULTS: 186 healthy women, aged between 25-35 years, equally divided in pregnancy and puerperium, were compared in terms of body image, with no significant difference between groups. Analyzing the item "cosmetic surgery is required after all pregnancies", there was a significant difference in puerperas and the item "cosmetic surgery is necessary for postpartum" was the principal. The comparison of BII, BDI, BAI values between pregnants and puerperas showed a significant difference between groups (p<0.00), with higher scores in postpartum patients. CONCLUSION: Body shape and physical dissatisfaction during pregnancy is linked with increased risk of depression in pregnancy and puerperium, pushing women to opt for cosmetic surgery, especially in puerperium.

Neurological outcomes of antenatal corticosteroid therapy.

AIM OF THE STUDY: The aim of the study was to investigate whether antenatal corticosteroid therapy (ACST) could impact neurological condition, as assessed through muscular tone, of prematurely born infants. METHODS: All 82 patients at risk of preterm delivery treated and delivered over 12 months were divided into two equal groups regarding the use of ACST. The investigated parameters were pregnancy complications, biophysical profile, Apgar score, gestational age of delivery and all postpartum complications. Neurological development and muscular tone were evaluated at the 1st, 3rd, 6th and 12th months of life using Vojta's method, which classifies muscular tone as good, hypotonic or hypertonic. RESULTS: After therapy, infants from the treated and control groups differed in biophysical profile, Apgar score, length of intensive care, occurrence of respiratory distress syndrome and intraventricular haemorrhage. During the follow-up, significantly more infants from the ACST group had good muscular tone when compared with those from the control group. Regression analysis showed that ASCT can significantly impact an infant's muscular tone. Still, the week of delivery and the complications such as diabetes mellitus, intrauterine growth restriction and respiratory distress syndrome, could change the association of ACST and infants' muscular tone. CONCLUSION: ACST was associated with the positive neurological outcomes of prematurely born infants when assessed through their muscular tone.

Predictors of IVF/ICSI success following treatment of endometriosis as the cause of primary infertility.

OBJECTIVES: Treatment of endometriosis prior to IVF/ICSI could be followed by the significant reduction of ovarian reserve. The aim is to identify potential markers of the IVF/ICSI outcome in patients with endometriosis associated infertility and to evaluate their clinical significance. MATERIAL AND METHODS: The prospective cohort study included 73 patients with primary infertility caused by endometriosis that were subjected to 77 IVF/ICSI cycles. Patients were classified into two groups. In the first group some type of treatment had previously been applied, and in the second group patients were immediately subjected to the IVF/ICSI procedures. RESULTS: When pregnancy was achieved, there were significantly more patients under 35 years of age, more patients with primary infertility duration up to 3 years, and more patients with endometriosis that was previously treated (77.4%) (p < 0.039). In the cases of the successful outcome Endometriosis Fertility Index > 7, lower basal FSH and FSH/LH ratio were found, as well as significantly higher basal E2, basal P4 and AMH. Significantly lower doses of gonadotropins were needed in cases of the successful outcome, and long protocol with agonists was more frequently used. Multivariate logistic regres-sion analysis showed that previous therapy of endometriosis, P4 ≥ 0.7 ng/mL, AMH ≥ 0.9 ng/mL, A class of embryos, and the use of long protocol with agonists were predictors of the successful IVF/ICSI outcome. CONCLUSIONS: Therapy for endometriosis, AMH and P4 levels appeared to be predictors for the successful IVF/ICSI outcome and the use of long protocol with agonists could be advised in these cycles.

Cesarean myomectomy in modern obstetrics: More light and fewer shadows.

The study aim was to evaluate management of myomas during cesarean section, the pro and cons and the outcomes of cesarean myomectomy. Moreover, we tried to investigate the long-term outcomes of cesarean myomectomy. The authors conducted a literature review using scientific databases, focusing on the benefits and outcomes of cesarean myomectomy and the recent trends regarding this topic, and identified relevant articles, related references and other papers citing them. Despite the demonstrated advantages of cesarean myomectomy, postponed myomectomy after cesarean section was recommended in some instances. Apart from recent reports on the safety and feasibility of cesarean myomectomy, the current literature also describes serious complications of cesarean myomectomy, including even maternal death. This poses a question about the reported rate of complications: whether it is underestimated in common practice. Although some studies strongly suggest the safety of cesarean myomectomy, data on the long-term outcomes of cesarean myomectomy in women are lacking. The risk-benefit ratio of cesarean myomectomy should be re-evaluated in the new century, given the increasing patient age, incidence of myoma in pregnancy, and the wide use of assisted reproductive techniques.

Cesarean myomectomy and possible risk factors for admission to intensive care unit - a retrospective study.

OBJECTIVES: Cesarean myomectomy (CM) allows to remove fibroids and to restore uterine anatomy during delivery combining two operations in one. It was opposed in the past due to surgical risks, although many reports showed that CM was not associated with increased morbidity The risk for admission to an intensive care unit (ICU) following CM - as an objective indicator of maternal morbidity potentially resulting in greater morbidity for patients, increased length of hospital stay and higher hospital costs - has been poorly evaluated in the literature. The aim of our investigation is to estimate risk factors for ICU admission after CM. MATERIAL AND METHODS: The patients were subdivided into two groups: 57 women who were postoperatively admitted to the ICU (study group), and 45 women not treated in the ICU (control group). The p-value of <0.05 was considered as statistically significant. RESULTS: Data showed no statistically significant differences with regard to demographic factors, comorbidity and indications for cesarean section, as well as experience of the surgeon, number of hysterotomies, and incidence of emergency CS between the two groups. The most common reason for admission to the ICU was intraoperative hemorrhage (61.40%). As for the surgical characteristics, the study group showed significant increase in the rates of intraoperative transfusion (p=0.000) and intraoperative hemorrhage (p=0.000), as well as prolongation of surgical time (p=0.002). Myoma type and size were also significantly different between the groups (p=0.003 and p=0.000, respectively). CONCLUSIONS: The most important factor contributing to ICU admission after CM is intraoperative hemorrhage in case of bigger myomas and prolonged surgeries.

Analysis of clinical, biological and obstetric factors influencing the decision to perform cesarean myomectomy.

OBJECTIVES: Myomas in pregnancy are associated with a significantly higher risk for cesarean section (CS). Cesarean myomectomy (CM), i.e. myomectomy during cesarean section, has been the source of much debate and was considered relatively contraindicated for many years. However, some authors advise to perform routine myomectomy during CS. The aim of our study was to determine factors influencing the intraoperative decision to perform CM. MATERIAL AND METHODS: A total of 185 patients with uterine myomas, who delivered by caesarean section during a 5-year period, were included in the study--102 patients underwent CM (study group) and 83 women underwent CS without myomectomy (control group). Clinical and obstetric data were recorded and processed for analysis. Using non-parametric correlation methods, we investigated the influence of different variables on the decision to perform CM. RESULTS: No differences were recorded between the two groups in terms of parity fetal presentation, gestational age, number of previous laparotomies, and previous myomectomy presence of diabetes and hypertension, indications and type of CS. Significant differences were detected in type and location of the myomas, contrary to their number and size, where no significant differences were registered. CONCLUSIONS: The most significant predictors of CM included age, surgical experience and type of myomas. CM is generally performed by experienced surgeons and in younger women. Also, it is more often performed in patients affected by pedunculated and subserosal myomas, and less frequent in case of intramural and multiple myomas.

Literature review, surgical decision making algorithm, and AGREE II-S comparison of national and international recommendations and guidelines in pelvic organ prolapse surgery.

The average lifespan has increased over time due to improvements in quality of life, leading to an aging population that stays healthy for longer. Pelvic organ prolapse (POP), whether uterine or vaginal, is a problem that severely impairs quality of life and imposes significant restrictions. The present study provides the reader with a summary of the many surgical techniques used in POP surgery, comparing international guidelines, offering an algorithm that is simple to understand, and allows the reader to quickly choose the table that includes the best surgical therapy for each individual. Using relevant keywords, the writers searched the PubMed and Scopus databases for relevant publications from 2000 to April 2023. Studies with cases of oncologic disorders or prior hysterectomy performed for another reason were not included in the analysis. Ten distinct international guidelines are highlighted and examined in the present study. We used the Appraisal of Guidelines for Research and Evaluation II-S (AGREE II-S) method to assess their quality, and incorporated the results into the conclusion. Worldwide, anterior colporrhaphy is the preferred method of treating anterior compartment abnormalities, and mesh is virtually always used when recurrence occurs (which happens in about half of the cases). Worldwide, posterior colporrhaphy is commonly used to repair posterior compartment abnormalities. Only a few national guidelines (the Iranian guideline, Acta Obstetricia et Gynecologica Scandinavica [AOGS], and the German-speaking countries) permit the use of mesh or xenograft in cases of recurrence. There is agreement on the abdominal approach (sacrocolpopexy) with mesh for treating apical deformities. Sacrospinous-hysteropexy is the standard method used to guide the vaginal approach; mesh is typically used to aid in this process. There are just three recommendations that do not include vaginal operations: HSE, AOGS, and Iran. Of obliteration techniques, colpocleisis is unquestionably the best. In conclusion, our analysis highlights the significance of customized methods in POP surgery, taking into account the requirements and preferences of each patient. To choose the best surgical therapy, criteria and patient features must be carefully considered.

Adenomyosis and fertility-sparing surgery: A literature appraisal.

Adenomyosis is an intricate pathological condition that negatively impacts the uterus. It is closely related to the more well-known endometriosis, with which it shares parallels in terms of diagnosis, therapy, and both microscopic and macroscopic features. The purpose of this narrative review is to give a clear univocal definition and outlook on the different, patient-adapted, surgical treatments. MEDLINE and PubMed searches on these topics were conducted from 1990 to 2022 using a mix of selected keywords. Papers and articles were identified and included in this narrative review after authors' revision and evaluation. From the literature analysis, authors reported the following surgical techniques: laparoscopic double/triple-flap method, laparotomic wedge resection of the uterine wall, laparotomic transverse H-incision of the uterine wall, laparotomic wedge-shaped excision, and laparotomic complete debulking excision by asymmetric dissection technique. Each of these techniques has strengths and weaknesses, but the literature data on the pregnancy rate are somewhat limited. The only certain information is the risk of uterine rupture up to 6.0% after surgical treatment for uterine adenomyosis. Over the years, the surgical approach continued to reach a positive result by minimally invasive treatment, with less hospitalization, less postoperative pain, and less blood loss. Over the years, the gynecological surgeon has gained the skills, training and increasingly sophisticated surgical techniques to target effective therapy. That's why a hysterectomy is no longer the only surgical resource to treat adenomyosis, but in patients who wish to preserve the fertility, there is a wide variety of surgical alternatives.

Insulin-sensitizing agents for infertility treatment in woman with polycystic ovary syndrome: a narrative review of current clinical practice.

PURPOSE: Polycystic ovary syndrome (PCOS) is an endocrine, metabolic, and reproductive disorder which, according to the Rotterdam criteria, affects up to 24% of women of childbearing age. Although the prevalence of infertility in this subpopulation of women is high, the optimal treatment has not been fully established yet. Insulin resistance is considered to be an important mechanism involved in the development of PCOS; hence, the aim of this narrative review is to present an overview of the current pharmacological insulin-sensitizing treatment modalities for infertile women with PCOS. METHODS: A MEDLINE and PubMed search for the years 1990-2023 was performed using a combination of keywords. Clinical trials with insulin sensitizers used for infertility treatment as well as analyses of systematic reviews and meta-analyses were evaluated. When deemed necessary, additional articles referenced in the retrieved papers were included in this narrative review. RESULTS: Several insulin-sensitizing compounds and various therapeutical protocols are available for infertility treatment of women with PCOS. Metformin is the most common adjuvant medication to induce ovulation in infertile women with PCOS and is more frequently administered in combination with clomiphene citrate than on its own. Recently, inositol and glucagon-like peptide-1 (GLP-1) receptor agonists have emerged as possible options for infertility treatment in PCOS. CONCLUSION: The future of medical treatment of PCOS women with infertility lies in a personalized pharmacological approach, which involves various compounds with different mechanisms of action that could modify ovarian function and endometrial receptivity, ultimately leading to better overall reproductive outcomes in these women.

Inevitable cesarean myomectomy following delivery through posterior hysterotomy in a case of uterine torsion.

BACKGROUND: Torsion of the pregnant uterus at term is a very infrequent obstetric event. It is usually associated with the presence of myoma or congenital deformities. Maternal prognosis is good after surgical treatment; however, prenatal mortality is high. CASE REPORT: We report a case of posterior low transverse hysterectomy in a case of uterine torsion at 38 weeks' gestation, due to a large myoma. At presentation, her cervix was unfavorable and cardiotocography showed spontaneous deceleration demanding delivery by cesarean section. Following delivery, it was realized that the incision had been made on the posterior wall of the uterus and that the uterus was axially rotated by 180 degrees. The mother recovered uneventfully and both mother and the baby were discharged on the fifth postoperative day. CONCLUSION: Obstetricians must have uterine torsion in mind when performing a cesarean section in patients with myomas.

Unraveling the Puzzle: Oocyte Maturation Abnormalities (OMAS).

Oocyte maturation abnormalities (OMAS) are a poorly understood area of reproductive medicine. Much remains to be understood about how OMAS occur. However, current knowledge has provided some insight into the mechanistic and genetic origins of this syndrome. In this study, current classifications of OMAS syndromes are discussed and areas of inadequacy are highlighted. We explain why empty follicle syndrome, dysmorphic oocytes, some types of premature ovarian insufficiency and resistant ovary syndrome can cause OMAS. We discuss live births in different types of OMAS and when subjects can be offered treatment with autologous oocytes. As such, we present this review of the mechanism and understanding of OMAS to better lead the clinician in understanding this difficult-to-treat diagnosis.

Fibroid Removal after Myomectomy: An Overview on the Problems of Power Morcellation.

The authors reviewed uterine fibroid (UF) morcellation and its potential consequences, notably a hypothetical spread and dissemination of occult uterine leiomyosarcoma (LMS) tissue, evaluating the effect of laparoscopic versus open myomectomies with and without morcellation on patients' outcomes, as well as related medical-legal issues. MEDLINE and PubMed search was performed for the years 1990-2021, using a combination of keywords on this topic. Relevant articles were identified and included in this narrative review. There is an individual risk, for all patients, for LMS diagnosis after myomectomy. However, the risk for occult LMS diagnosis during a laparoscopic myomectomy is generally reduced when the guidelines of scientific societies are followed, with an overall benefit from the laparoscopic approach with morcellation in appropriate cases. Gynecological societies do not ban morcellation and laparoscopic hysterectomy/myomectomy per se, but recommend their use on the basis of the patients' clinical characteristics. It is suggested for gynecologists to provide detailed information to patients when obtaining an informed consent for open or laparoscopic hysterectomy/myomectomy. A detailed preoperative assessment of patients and the risk benefit ratio of laparoscopic morcellation of uterine mass could overcome the "a priori" banning of the morcellation technique.

Gestational Diabetes Mellitus and Antenatal Corticosteroid Therapy-A Narrative Review of Fetal and Neonatal Outcomes.

BACKGROUND: There, we review the pathogenesis of gestational diabetes mellitus (GDM), its influence on fetal physiology, and neonatal outcomes, as well as the usage of antenatal corticosteroid therapy (ACST) in pregnancies complicated by GDM. METHODS: MEDLINE and PubMed search was performed for the years 1990-2022, using a combination of keywords on such topics. According to the aim of the investigation, appropriate articles were identified and included in this narrative review. RESULTS: GDM is a multifactorial disease related to unwanted pregnancy course and outcomes. Although GDM has an influence on the fetal cardiovascular and nervous system, especially in preterm neonates, the usage of ACST in pregnancy must be considered taking into account maternal and fetal characteristics. CONCLUSIONS: GDM has no influence on neonatal outcomes after ACST introduction. The ACST usage must be personalized and considered according to its gestational age-specific effects on the developing fetus.
