RESUMEN

OBJECTIVES: There is controversial evidence that acidification of vaginal pH may increase the efficacy of vaginal prostaglandins in labor induction, with research being mainly focused on misoprostol. This study aims to evaluate the impact of this intervention on the progress of labor induction with dinoprostone (PGE2) vaginal tablet. METHODS: This double-blind, parallel-group, randomized study was conducted between October 2021 and December 2022 at Alexandra General Hospital, Athens, Greece. A total of 230 women with singleton, full term pregnancy that were scheduled for labor induction were randomly divided into two groups: Group A, who received acidic vaginal wash (5 % acetic acid) and Group B, who received a normal saline vaginal wash. Afterwards, participants received a vaginal tablet of 3 mg dinoprostone every 6 h (maximum two doses). RESULTS: There were no statistically significant differences in mode of delivery, duration of different labor stages, Bishop score changes and possible complications. Participants in the acidification group needed less often labor augmentation with oxytocin and epidural anesthesia (p=0.03). CONCLUSIONS: Vaginal acidification seems to have no effect on the efficacy of the dinoprostone vaginal tablet. Even though it may reduce the need for oxytocin augmentation, there is no apparent benefit on clinical outcomes, such as reduction in cesarean section rates or shorter labor duration. Future research is necessary in order to validate these findings.

RESUMEN

OBJECTIVES: Diaphragmatic stripping is a standard procedure that is performed in a significant proportion of patients undergoing surgical cytoreduction for advanced ovarian cancer. The objective of the present study is to evaluate morbidity and survival outcomes among patients offered diaphragmatic surgery for primary diagnosed optimally resected ovarian cancer. STUDY DESIGN: We conducted a retrospective cohort study, identifying patients that were offered surgery between 2016 and 2021 for primary diagnosis of ovarian cancer. Cases that had diaphragmatic stripping or partial diaphragmatic resection were selected and compared to cases that did not require this procedure. Kaplan-Meier and Cox-regression analyses were applied to evaluate survival outcomes. RESULTS: Overall, 61 patients that had diaphragmatic stripping were identified. Severe postoperative complications (Clavien-Dindo 3 + ) were noted in 19 patients (31 %). Survival analyses denoted that the stage of the disease at the time of diagnosis, as well as the timing of the surgical procedure (PDS vs IDS) and the completion of tumor debulking were factors that significantly affected the recurrence free and overall survival of patients. Severe postoperative morbidity was a significant predictor of the overall survival. Multivariate cox-regression analysis that was adjusted for the stage of the disease revealed that preoperative pleural effusion, optimal (compared to complete) tumor resection and the occurrence of postoperative complications significantly affected the overall survival of patients. Compared to patients that did not have diaphragmatic surgery, patients submitted to diaphragmatic stripping or resection had improved progression free and overall survival rates, irrespective of the stage of the disease at diagnosis or the adequacy of resection status. CONCLUSIONS: Diaphragmatic surgery is feasible in advanced ovarian cancer patients with acceptable morbidity that mainly refers to postoperative pleural effusion. Its positive impact on patients' survival requires further investigation.

RESUMEN

Cervical cancer represents a global health issue as it is mostly encountered in women of reproductive age, while at the same time, survival outcomes seem to have remained constant during the last two decades. The need to implement fertility-sparing strategies as well as to decrease the morbidity that accompanies radical treatment has been extensively studied. During the last decade, several randomized clinical trials have been released, resulting in significant advances in the surgical treatment of early-stage disease. At the same time, evidence about the surgical treatment of advanced-stage disease as well as recurrent disease has gradually appeared and seems to be promising, thus leading the point forward towards personalized medicine that will remove the surgical barriers that seem concrete in our era. Nevertheless, the discrepancies in perioperative morbidity and survival outcomes that were observed among published studies raise several questions. In the present article, we chose to review the gray fields in the surgical treatment of early-stage and advanced-stage cervical cancer. Studies that are based on strong evidence that support current clinical practice are compared to smaller cohorts that present novel data that may form the basis for future research, and issues that remain poorly explored are discussed in an effort to help establish a consensus for future research development.

RESUMEN

An association between thrombocytosis and cancer progression and decreased survival has been observed for various forms of cancer. The aim of this study was to evaluate the impact of pre-treatment thrombocytosis on ovarian cancer survival. Medline, Scopus, Clinicaltrials.gov, Cochrane Central Register of Controlled Trials CENTRAL and Google Scholar were searched systematically for studies that compared survival outcomes of patients with ovarian cancer who had pre-treatment thrombocytosis with survival outcomes of patients with normal platelet counts. Fourteen articles were retrieved, with a total of 5414 patients with ovarian cancer. The methodological quality of included studies ranged between moderate and high. Patients with advanced stage disease were more likely to have pre-treatment thrombocytosis, and this was associated with lower rates of optimal debulking. Thrombocytosis was also associated with increased likelihood of recurrence of ovarian cancer [hazard ratio (HR) 2.01, 95 % confidence interval (CI) 1.34-3.01] and increased risk of death from ovarian cancer (HR 2.29, 95 % CI 1.35-3.90). The incidence of deep vein thrombosis was comparable in both groups (odds ratio 1.62, 95 % CI 0.48-5.46). Considering these findings, it is evident that pre-treatment thrombocytosis in patients with ovarian cancer is associated with increased risk of recurrence and death. Pre-treatment thrombocytosis is a potential sign of advanced stage disease, and may be predictive of suboptimal tumour debulking during surgery. Its association with other factors that affect survival, including platinum resistance and response to targeted therapy, remains poorly explored, although preliminary data suggest a potential correlation.

RESUMEN

Background and Objectives: The impact of positive peritoneal cytology has been a matter of controversy in early-stage endometrial cancer for several years. The latest staging systems do not take into consideration its presence; however, emerging evidence about its potential harmful effect on patient survival outcomes suggests otherwise. In the present systematic review and meta-analysis, we sought to accumulate current evidence. Materials and Methods: Medline, Scopus, the Cochrane Central Register of Controlled Trials CENTRAL, Google Scholar and Clinicaltrials.gov databases were searched for relevant articles. Effect sizes were calculated in Rstudio using the meta function. A sensitivity analysis was carried out to evaluate the possibility of small-study effects and p-hacking. Trial sequential analysis was used to evaluate the adequacy of the sample size. The methodological quality of the included studies was assessed using the Newcastle-Ottawa scale. Results: Fifteen articles were finally included in the present systematic review that involved 19,255 women with early-stage endometrial cancer. The Newcastle-Ottawa scale indicated that the majority of included studies had a moderate risk of bias in their selection of participants, a moderate risk of bias in terms of the comparability of groups (positive peritoneal cytology vs. negative peritoneal cytology) and a low risk of bias concerning the assessment of the outcome. The results of the meta-analysis indicated that women with early-stage endometrial cancer and positive peritoneal cytology had significantly lower 5-year recurrence-free survival (RFS) (hazards ratio (HR) 0.26, 95% CI 0.09, 0.71). As a result of the decreased recurrence-free survival, patients with positive peritoneal cytology also exhibited reduced 5-year overall survival outcomes (HR 0.50, 95% CI 0.27, 0.92). The overall survival of the included patients was considerably higher among those that did not have positive peritoneal cytology (HR 12.76, 95% CI 2.78, 58.51). Conclusions: Positive peritoneal cytology seems to be a negative prognostic indicator of survival outcomes of patients with endometrial cancer. Considering the absence of data related to the molecular profile of patients, further research is needed to evaluate if this factor should be reinstituted in future staging systems.

RESUMEN

INTRODUCTION: Patient awareness of postoperative lymphedema in the field of gynecologic oncology has been poorly documented in the international literature. We wished to capture and document the awareness among gynecological cancer survivors about postoperative lymphedema, including aspects such as the adequacy of perioperative counseling, management, and quality of life. METHODS: A web-based survey comprising 25 multiple-choice questions was distributed to gynecological cancer advocacy groups within the European Network of Gynecological Cancer Advocacy Groups (ENGAGe) group. The survey was validated in a pilot group of gynecological patients prior to distribution. RESULTS: Overall, 386 women from 20 countries completed the questionnaire. Only half of the patients (n = 211) knew what lymphedema is, whereas 52% of the respondents stated that they were never informed at their pre-operative assessment about the potential risk of developing lymphedema. Fifty-three percent of those women who were informed about the risk and management of lymphedema received information through self-initiative, connecting mainly with patient groups or online. Approximately 84% of patients with lymphedema reported that they informed their doctor about their symptoms. Ninety-four patients (55.3%, which is not 55% of the 386) were treated for lymphedema. Forty-five women out of 136 reported that lymphedema significantly affected their everyday lives. DISCUSSION: We report a large lack of awareness and a significant gap of knowledge about the risks and treatment options related to postoperative lymphedema among gynecological cancer survivors. Institutional practice routines and awareness among professionals need to be urgently recalled and adapted to adequately inform and support gynecological cancer patients.

RESUMEN

Background: Assessing fetal growth constitutes a fundamental aim within the realm of prenatal care. Impaired prenatal growth increases the risk of perinatal mortality, morbidity, and poor newborn outcomes. Growth restriction increases the risk of premature birth problems, as well as the risk of poor neurodevelopmental outcomes and future non-communicable disorders such as hypertension and metabolic syndrome as adults. The objective of this systematic review is to accumulate current literature evidence to assess the patterns of serum adipokine levels among women with growth-restricted fetuses and assess their potential alterations in those high-risk pregnancies. Methods: Medline, Scopus, CENTRAL, Clinicaltrials.gov, and Google Scholar databases were systematically searched from inception until 31 March 2023. All observational studies reporting serum adipokine values among women with appropriately grown and growth-restricted fetuses were held eligible. Results: The current systematic review encompassed a total of 20 studies, incorporating a patient population of 1850 individuals. Maternal blood leptin emerged as the adipokine most investigated, as evidenced by 13 studies encompassing a collective sample size of 1081 patients, all of which explored its potential correlation with intrauterine growth restriction. Elevated levels of leptin were detected in fetuses with intrauterine growth restriction, although the observed difference did not reach statistical significance. Furthermore, regarding adiponectin, the meta-analysis conducted indicated that there were not any statistically significant differences observed in the mean values of adiponectin. The available data on the remaining three adipokines were extremely limited, making it difficult for any solid conclusions to be extracted. Conclusions: Though limited and inconsistent, the existing data suggest that fetal growth restriction is not linked to leptin, adiponectin, visfatin, resistin, or RBP4. More substantial prospective studies are needed to comprehend the importance of established and novel adipokines.

RESUMEN

OBJECTIVE: The chemotherapy response score (CRS) has been widely adopted as a predictive tool for ovarian cancer survival. In the present study, we seek to define differences in survival rates among patients grouped in the traditionally established three-tiered system and those who have not been offered debulking surgery. STUDY DESIGN: We designed a retrospective cohort study involving women treated with chemotherapy and offered interval or late debulking surgery for ovarian cancer. Twenty-eight women were not considered for a debulking procedure for various reasons. Of the 89 women who were finally offered interval debulking or late debulking surgery, 28 had a CRS 1 score, 34 had a CRS 2 score and 27 had a CRS 3 score. RESULTS: Significant differences were noted in the progression-free survival (PFS) and overall survival (OS) of patients based on the CRS stratification, although survival rates were considerably longer for all three groups compared to those of patients who were not offered surgery. Cox regression univariate analysis revealed that suboptimal debulking and CRS 1 or no surgery had a significant negative impact on PFS and OS rates. The binary stratification of CRS (CRS 1-2 vs CRS 3) revealed comparable differences in the PFS and OS to those in the groups that were stratified as platinum resistant and platinum sensitive. CONCLUSION: The chemotherapy response score is a significant determinant of ovarian cancer survival that helps evaluate the risk of early disease relapse and death and may soon be useful in guiding patient-tailored treatment.

RESUMEN

PURPOSE: To evaluate the awareness and existing knowledge of a portion of the Greek population about prevention, screening, and HPV vaccination. METHODS: A questionnaire designed in Google forms has been distributed through social media between June 2021 and December 2021 in men and women aged > 16 years old. Statistical analysis was performed using the SPSS 20.0 program. Inferential analysis was performed to evaluate differences in responses among men and women. RESULTS: We enrolled 2685 participants. Of those, 2285 were women, 386 were men, while 14 respondents chose not to respond to this question. Various age groups were detected with those aged between 26 and 30 years old being the predominant one. Participants with a higher education constituted 36.5% of the population. Most respondents were married (59.8%). In socioeconomic terms 75.5% of participants were employed whereas, monthly income ranged between 1000 and 1500 euros in the predominant group (36.8%). Only 40% of females and 3.9% of males were vaccinated against HPV. Adolescent immunization, acceptability rates reached 92.7% among female and 82.1% among male responders. Although, only a small proportion of the participants were not aware of the existence of HPV, 24.1% of males and 23.4% of females had the impression that condom use may provide absolute immunity to HPV and only 51.6% of males and 60.4% of females were aware about the high prevalence of HPV in the general population. Logistic regression analysis indicated that male participants as well as those aged > 50 years and those choosing to reject vaccination had decreased knowledge of the basic pathophysiology of HPV infection, as well as knowledge related to the existence and use of HPV DNA as a screening tool and the existence and efficacy of HPV vaccination. CONCLUSION: Our results indicate that although awareness of the existence of HPV infection is high in Greek general population, the actual perception of the pathophysiology of transmission and importance of HPV testing and vaccination is low. Targeting specific population groups is essential to help increase HPV coverage and screening.

RESUMEN

BACKGROUND: Despite the considerable progress made in recent years in fetal assessment, the etiology of fetal growth disturbances is not as yet well understood. In an effort to enhance our knowledge in this area, we investigated the associations of the amniotic fluid angiotensinogen of the renin-angiotensin system with fetal growth abnormalities. METHODS: We collected amniotic fluid samples from 70 pregnant women who underwent amniocentesis during their early second trimester. Birth weight was documented upon delivery, after which the embryos corresponding to the respective amniotic fluid samples were categorized into three groups as follows: small for gestational age (SGA), appropriate for gestational age (AGA), and large for gestational age (LGA). Amniotic fluid angiotensinogen levels were determined by using ELISA kits. RESULTS: Mean angiotensinogen values were 3885 ng/mL (range: 1625-5375 ng/mL), 4885 ng/mL (range: 1580-8460 ng/mL), and 4670 ng/mL (range: 1995-7250 ng/mL) in the SGA, LGA, and AGA fetuses, respectively. The concentrations in the three groups were not statistically significantly different. Although there were wide discrepancies between the mean values of the subgroups, the large confidence intervals in the three groups negatively affected the statistical analysis. However, multiple regression analysis revealed a statistically significant negative correlation between the angiotensinogen levels and gestational age and a statistically significant positive correlation between the birth weight and angiotensinogen levels. DISCUSSION: Our findings suggest that fetal growth abnormalities did not correlate with differences in the amniotic fluid levels of angiotensinogen in early second trimester pregnancies. However, increased angiotensinogen levels were found to be consistent with a smaller gestational age at birth and increased BMI of neonates.

RESUMEN

Objective: Maternal obesity has been previously linked to increased risk of preterm birth; however, the actual pathophysiology behind this observation remains unknown. Cervical length seems to differentiate among overweight, obese and extremely obese patients, compared to normal weight women. However, to date the actual association between body mass index and cervical length remains unknown. In this systematic review, accumulated evidence is presented to help establish clinical implementations and research perspectives. Methods: We searched Medline, Scopus, the Cochrane Central Register of Controlled Trials CENTRAL, Google Scholar, and Clinicaltrials.gov databases from inception till February 2023. Observational studies that reported on women undergone ultrasound assessment of their cervical length during pregnancy were included, when there was data regarding their body mass index. Statistical meta-analysis was performed with RStudio. The quality of the included studies was assessed using the Newcastle-Ottawa Quality Assessment Scale (NOS). Results: Overall, 20 studies were included in this systematic review and 12 in the meta-analysis. Compared to women with normal weight, underweight women were not associated with increased risk of CL < 15 mm or < 30 mm and their mean CL was comparable (MD -1.51; 95% CI -3.07, 0.05). Overweight women were found to have greater cervical length compared to women with normal weight (MD 1.87; 95% CI 0.52, 3.23) and had a lower risk of CL < 30 mm (OR 0.65; 95% CI 0.47, 0.90). Conclusion: Further research into whether BMI is associated with cervical length in pregnant women is deemed necessary, with large, well-designed, prospective cohort studies with matched control group.

RESUMEN

Malnutrition significantly impacts the post-operative process of gynecological cancer patients. A prominent variable for determining perioperative morbidity is the Prognostic Nutritional Index (PNI). To investigate PNI's predictive value on the risk of post-operative infections, we conducted a prospective cohort study involving women who underwent surgery for gynecological malignancies. Out of the 208 patients enrolled, 28 (13.5%) were malnourished and post-operative infections occurred in 43 patients. Notably, there was a significant difference in PNI between patients who developed infections and those who did not (p = 0.027), as well as between malnourished patients and those with normal nutritional status (p = 0.043). Univariate analysis showed that preoperative PNI predicts the risk of post-operative infections better than post-operative white blood cell count (AUC of 0.562 vs 0.375). However, the most accurate diagnostic results in the multivariate analysis were obtained from random forest and classification tree models (AUC of 0.987 and 0.977, respectively). Essentially, PNI and post-operative white blood cell count provided the best information gain according to rank probabilities. In conclusion, PNI appears to be a critical parameter that merits further investigation during the preoperative evaluation of gynecological malignancies.

RESUMEN

INTRODUCTION: A splenectomy is frequently performed during debulking surgery for advanced ovarian cancer. Its impact on perioperative and survival outcomes remains questionable as current evidence is conflicting. In the present study, we sought to determine the factors that affect survival rates in ovarian cancer patients that undergo a splenectomy as part of maximal-effort cytoreduction. PATIENTS AND METHODS: A retrospective chart review was conducted that included all epithelial ovarian cancer patients that had surgical cytoreduction for advanced epithelial ovarian cancer. Differences among splenectomized and non splenectomized patients were evaluated as well as the impact of known risk factors on survival outcomes of splenectomized patients. RESULTS: Overall, 245 patients were identified and 223 were included in the present series, of whom 91 had a splenectomy. Recurrence rates as well as death rates were comparable among splenectomized and non-splenectomized patients; however, both the disease-free survival (log-rank = 0.001), as well as the overall survival of splenectomized patients (log-rank = 0.006), was shorter. Thrombotic events as well as rates of pulmonary embolism were comparable. Sepsis was more common among splenectomized patients. The site of splenic metastases did not influence patients' survival. Among splenectomized patients, those offered primary debulking had longer progression-free survival (log-rank = 0.042), although their overall survival did not differ compared to patients submitted to interval debulking. Complete debulking significantly improved the overall survival compared to optimal debulking (log-rank = 0.047). Splenectomized patients that developed sepsis had worse overall survival (log-rank = 0.005). DISCUSSION: The findings of our study support the feasibility of splenectomy in advanced epithelial ovarian cancer; however, its impact on patients' survival is considerable. Therefore, every effort should be made to avoid splenic injury which will result in unintended splenectomy for non-oncological reasons.

RESUMEN

PURPOSE: Magnesium sulfate (MgSO4) has been widely used in obstetrics as a mean to help decrease maternal and neonatal morbidity in various antenatal pathology. As a factor, it seems to regulate immunity and can, thus, predispose to infectious morbidity. To date, it remains unknown if its administration can increase the risk of chorioamnionitis. In the present meta-analysis, we sought to accumulate the available evidence. METHODS: We systematically searched Medline, Scopus, Clinicaltrials.gov, EMBASE, Cochrane Central Register of Controlled Trials CENTRAL, and Google Scholar databases in our primary search along with the reference lists of electronically retrieved full-text papers. RESULTS: Eight studies were included that investigated the incidence of chorioamnionitis among parturient that received MgSO4 and control patients. Magnesium sulfate was administered in 3229 women and 3330 women served as controls as they did not receive MgSO4. The meta-analysis of data revealed that there was no association between the administration of magnesium sulfate and the incidence of chorioamnionitis (OR 0.98, 95% CI 0.73, 1.32). Rucker's analysis revealed that small studies did not significantly influence the statistical significance of this finding (OR 1.12, 95% CI 0.82, 1.53). Trial sequential analysis revealed that the required number to safely interpret the primary outcome was not reached. Two studies evaluated the impact of MgSO4 in neonates delivered in the setting of chorioamnionitis. Neither of these indicated the presence of a beneficial effect in neonatal morbidity, including the risk of cerebral palsy, intraventricular hemorrhage, necrotizing enterocolitis, bronchopulmonary dysplasia, sepsis, stillbirth, or neonatal death. CONCLUSION: Current evidence indicates that magnesium sulfate is not associated with an increased risk of maternal chorioamnionitis. However, it should be noted that its effect on neonatal outcomes of offspring born in the setting of chorioamnionitis might be subtle if any, although the available evidence is very limited.

RESUMEN

Ovarian cancer is a deadly disease that affects thousands of women worldwide. Integrins, transmembrane receptors that mediate cell adhesion and signaling, play important roles in ovarian cancer progression, metastasis, and drug resistance. Dysregulated expression of integrins is implicated in various cellular processes, such as cell migration, invasion, and proliferation. Emerging evidence suggests that microRNAs (miRNAs) can regulate integrin expression and function, thus affecting various physiological and pathological processes, including ovarian cancer. In this article, we review the current understanding of integrin-mediated cellular processes in ovarian cancer and the roles of miRNAs in regulating integrins. We also discuss the therapeutic potential of targeting miRNAs that regulate integrins for the treatment of ovarian cancer. Targeting miRNAs that regulate integrins or downstream signaling pathways of integrins may provide novel therapeutic strategies for inhibiting integrin-mediated ovarian cancer progression.

RESUMEN

BACKGROUND: Emerging evidence suggests the clinical utility of N terminal pro B type natriuretic peptide (NT-proBNP) in multiple cardiac and pulmonary abnormalities both in adult and pediatric populations. To date, however, there is no consensus regarding its efficacy for the prediction and severity of bronchopulmonary dysplasia in premature neonates. The objective of the present meta-analysis was to determine differences in NT-proBNP among neonates that develop BPD or die from BPD and to evaluate if there is relative information on the diagnostic accuracy of the method. METHODS: We conducted a systematic search according to the PRISMA guidelines and looked into Medline (1966-2023), Scopus (2004-2023), Clinicaltrials.gov (2008-2023), EMBASE (1980-2023), Cochrane Central Register of Controlled Trials CENTRAL (1999-2022) and Google Scholar (2004-2023) together with the reference lists from included studies. The potential risk of bias encountered in our study was evaluated using the QUADAS -2 tool. Finally, a total of 9 studies met the eligibility criteria, comprising 1319 newborns, from which 397 developed BPD and 922 were unaffected controls. RESULTS: The results retrieved from our meta-analysis showed that newborns suffering from BPD had notably elevated NT-proBNP levels after birth when compared with healthy neonates (SMD 2.57, 95% CI 0.41, 4.72). The summary effect of the AUC meta-analysis showed that NT-proBNP was very accurate in detecting neonates at risk of developing severe BPD or dying from the disease (AUC -0.16, 95% CI -0.23, -0.08). No studies reported data relevant to the sensitivity and/or specificity of the method in diagnosing BPD. CONCLUSION: Serum NT-proBNP levels represent a potential future biomarker with great diagnostic validity for the prediction of BPD complicating preterm deliveries. The limited amount of studies included and the significant variations in cutoff values and timing of measurement still restrict the application of NT-proBNP as an established clinical biomarker for BPD. The design of larger prospective studies will provide a more representative number of participants and will address the discrepancies in existing literature.

RESUMEN

Bladder malignancy represents the fourth most common cancer in men and the eighth in women in the western world. Women under 75 years of age have a risk of 0.5-1% of developing bladder cancer. The diagnosis usually occurs between 65 and 70 years of age, whereas the mortality rate for women varies from 0.5 to 4 per 100,000 every year. Nulliparous women present a greater risk than women who have given birth. The risk is further decreased when parity increases. Theoretically, hormonal changes occurring during pregnancy play a protective role. Smoking and occupational exposure to specific chemicals are the most common risk factors of bladder cancer. Other risk factors such as chronic urinary tract inflammation, cyclophosphamide, radiotherapy, and familial correlation have been reported. The aim of this review is to highlight a rare combination, which is the co-existence of bladder malignancy and pregnancy. We present thirteen different cases of women who were diagnosed with malignant bladder tumors during their pregnancy. A review of the literature was conducted, focusing on the unspecific symptoms, possible diagnostic tools, and suitable treatment modalities. The management of bladder cancer in pregnancy is a challenging process. The fragile balance between the possible complications of pregnancy and maternal health is yet to be discussed.

RESUMEN

Maternal health during gestational period is undoubtedly critical in shaping optimal fetal development and future health of the offspring. Gestational diabetes mellitus is a metabolic disorder occurring in pregnancy with an alarming increasing incidence worldwide during recent years. Over the years, there is a growing body of evidence that uncontrolled maternal hyperglycaemia during pregnancy can potentially have detrimental effect on the neurodevelopment of the offspring. Both human and animal data have linked maternal diabetes with motor and cognitive impairment, as well as autism spectrum disorders, attention deficit hyperactivity disorder, learning abilities and psychiatric disorders. This review presents the available data from current literature investigating the relationship between maternal diabetes and offspring neurodevelopmental impairment. Moreover, possible mechanisms accounting for the detrimental effects of maternal diabetes on fetal brain like fetal neuroinflammation, iron deficiency, epigenetic alterations, disordered lipid metabolism and structural brain abnormalities are also highlighted. On the basis of the evidence demonstrated in the literature, it is mandatory that hyperglycaemia during pregnancy will be optimally controlled and the impact of maternal diabetes on offspring neurodevelopment will be more thoroughly investigated.

RESUMEN

Twin pregnancies demonstrate a 2-3-fold higher chance of developing PE compared to singletons, and recent evidence has demonstrated that the sFLT1/PIGF ratio is strongly associated with PE, adverse pregnancy outcomes, as well as imminent deliveries due to PE complications. The primary objective of this systematic review was to summarise the available data on the levels of sFLT1, PlGF and their ratios in twin pregnancies and to investigate their association with the development of PE, adverse pregnancy outcomes and the timing of the delivery. A systematic search of Ovid Embase, Web of Science, Science Direct, PubMed, Ovid Medline, Google Scholar and CINAHL was carried out. sFLT1 levels and the sFLT1/PIGF ratio appeared higher in twins compared to singleton pregnancies, especially in the third trimester, while PlGF levels appeared higher up until the third trimester, with their values showing no difference or being even lower than in singletons thereafter. The sFLT1/PIGF ratio has been reported to be an independent marker of adverse outcomes related to pre-eclampsia and is associated with the mean time until delivery in an inverse manner. Further research is required in order to establish the optimal sFLT1/PIGF cut-off values and to stratify the risk of adverse outcomes in twin pregnancies.

RESUMEN

BACKGROUND: Abnormal fetal growth is associated with adverse perinatal and long-term outcomes. The pathophysiological mechanisms underlying these conditions are still to be clarified. Nerve growth factor (NGF) and neurotrophin-3 (NT-3) are two neurotrophins that are mainly involved in the neuroprotection process, namely promotion of growth and differentiation, maintenance, and survival of neurons. During pregnancy, they have been correlated with placental development and fetal growth. In this study, we aimed to determine the early 2nd trimester amniotic fluid levels of NGF and NT-3 and to investigate their association with fetal growth. METHODS: This is a prospective observational study. A total of 51 amniotic fluid samples were collected from women undergoing amniocentesis early in the second trimester and were stored at -80 °C. Pregnancies were followed up until delivery and birth weight was recorded. Based on birth weight, the amniotic fluid samples were divided into three groups: appropriate for gestational age (AGA), small for gestational age (SGA), and large for gestational age (LGA). NGF and NT-3 levels were determined by using Elisa kits. RESULTS: NGF concentrations were similar between the studied groups; median values were 10.15 pg/mL, 10.15 pg/mL, and 9.14 pg/mL in SGA, LGA, and AGA fetuses, respectively. Regarding NT-3, a trend was observed towards increased NT-3 levels as fetal growth velocity decreased; median concentrations were 11.87 pg/mL, 15.9 pg/mL, and 23.5 pg/mL in SGA, AGA, and LGA fetuses, respectively, although the differences among the three groups were not statistically significant. CONCLUSIONS: Our findings suggest that fetal growth disturbances do not induce increased or decreased production of NGF and NT-3 in early second trimester amniotic fluid. The trend observed towards increased NT-3 levels as fetal growth velocity decreased shows that there may be a compensatory mechanism in place that operates in conjunction with the brain-sparing effect. Further associations between these two neurotrophins and fetal growth disturbances are discussed.
