RESUMEN

BACKGROUND: The maternal cardiovascular profile of patients who develop late fetal growth restriction has yet to be well characterized, however, a subclinical impairment in maternal hemodynamics and cardiac function may be present before pregnancy and may become evident because of the hemodynamic alterations associated with pregnancy. OBJECTIVE: This study aimed to investigate if maternal hemodynamics and the cardiovascular profile might be different in the preclinical stages (22-24 weeks' gestation) in cases of early and late fetal growth restriction in normotensive patients. STUDY DESIGN: This was a prospective echocardiographic study of 1152 normotensive nulliparous pregnant women at 22 to 24 weeks' gestation. The echocardiographic evaluation included morphologic parameters (left ventricular mass index and relative wall thickness, left atrial volume index) and systolic and diastolic maternal left ventricular function (ejection fraction, left ventricular global longitudinal strain, E/A ratio, and E/e' ratio). Patients were followed until the end of pregnancy to note the development of normotensive early or late fetal growth restriction. RESULTS: Of the study cohort, 1049 patients had no complications, 73 were classified as having late fetal growth restriction, and 30 were classified as having early fetal growth restriction. In terms of left ventricular morphology, the left ventricular end-diastolic diameter was greater in uneventful pregnancies (4.84±0.28 cm) than in late (4.67±0.26 cm) and in early (4.55±0.26 cm) (P<.001) fetal growth restriction cases, whereas left ventricular end-systolic diameter was smaller in uneventful pregnancies (2.66±0.39 cm) than in late (2.83±0.40 cm) and in early (2.82±0.38 cm) (P<.001) fetal growth restriction cases. The relative wall thickness was slightly higher in early (0.34±0.05) and late (0.35±0.04) fetal growth restriction cases than in uneventful pregnancies (0.32±0.05) (P<.05). In terms of systolic left ventricular function, at 22 to 24 weeks' gestation, cardiac output was higher in uneventful pregnancies (6.58±1.07 L/min) than in late (5.40±0.97 L/min) and in early (4.76±1.05 L/min) (P<.001) fetal growth restriction cases with the lowest values in the early-onset group. Left ventricular global longitudinal strain was lower in appropriate for gestational age neonates (-21.6%±2.0%) and progressively higher in late (-20.1%±2.2%) and early (-18.5%±2.3%) (P<.001) fetal growth restriction cases. In terms of diastolic left ventricular function, the E/e' ratio showed intermediate values in the late fetal growth restriction group (7.90±2.73) when compared with the appropriate for gestational age group (7.24±2.43) and with the early fetal growth restriction group (10.76±3.25) (P<.001). The total peripheral vascular resistance was also intermediate in the late fetal growth restriction group (1300±199 dyne·s·cm-5) when compared with the appropriate for gestational age group (993±175 dyne·s·cm-5) and the early fetal growth restriction group (1488±255 dyne.s.cm-5) (P<.001). CONCLUSION: Early and late fetal growth restriction share similar maternal hemodynamic and cardiovascular profiles with a different degree of expression. These features are already present at 22 to 24 weeks' gestation and are characterized by a hypodynamic state. The degree of these cardiovascular changes may influence the timing of the manifestation of the disease; a hypovolemic, high resistance, low cardiac output state might be associated with early-onset fetal growth restriction, whereas a milder hypovolemic state seems to favor the development of the disease in the final stages of pregnancy.

RESUMEN

OBJECTIVE: The Italian Association of Preeclampsia (AIPE) and the Italian Society of Perinatal Medicine (SIMP) developed clinical questions on maternal hemodynamics state of the art. STUDY DESIGN: AIPE and SIMP experts were divided in small groups and were invited to propose an overview of the existing literature on specific topics related to the clinical questions proposed, developing, wherever possible, clinical and/or research recommendations based on available evidence, expert opinion, and clinical importance. Draft recommendations with a clinical rationale were submitted to 8th AIPE and SIMP Consensus Expert Panel for consideration and approval, with at least 75% agreement required for individual recommendations to be included in the final version. RESULTS: More and more evidence in literature underlines the relationship between maternal and fetal hemodynamics, as well as the relationship between maternal cardiovascular profile and fetal-maternal adverse outcomes such as fetal growth restriction and hypertensive disorders of pregnancy. Experts agreed on proposing a classification of pregnancy hypertension, complications, and cardiovascular states based on three different hemodynamic profiles depending on total peripheral vascular resistance values: hypodynamic (>1,300 dynes·s·cm-5), normo-dynamic, and hyperdynamic (<800 dynes·s·cm-5) circulation. This differentiation implies different therapeutical strategies, based drugs' characteristics, and maternal cardiovascular profile. Finally, the cardiovascular characteristics of the women may be useful for a rational approach to an appropriate follow-up, due to the increased cardiovascular risk later in life. CONCLUSION: Although the evidence might not be conclusive, given the lack of large randomized trials, maternal hemodynamics might have great importance in helping clinicians in understanding the pathophysiology and chose a rational treatment of patients with or at risk for pregnancy complications. KEY POINTS: · Altered maternal hemodynamics is associated to fetal growth restriction.. · Altered maternal hemodynamics is associated to complicated hypertensive disorders of pregnancy.. · Maternal hemodynamics might help choosing a rational treatment during hypertensive disorders..

RESUMEN

BACKGROUND: The functional maternal-fetal hemodynamic unit includes fetal umbilical vein flow and maternal peripheral vascular resistance. OBJECTIVE: This study investigated the relationships between maternal and fetal hemodynamics in a population with suspected fetal growth restriction. STUDY DESIGN: This was a prospective study of normotensive pregnancies referred to our outpatient clinic for a suspected fetal growth restriction. Maternal hemodynamics measurement was performed, using a noninvasive device (USCOM-1A) and a fetal ultrasound evaluation to assess fetal biometry and velocimetry Doppler parameters. Comparisons among groups were performed with 1-way analysis of variance with Student-Newman-Keuls correction for multiple comparisons and with Kruskal-Wallis test where appropriate. The Spearman rank coefficient was used to assess the correlation between maternal and fetal hemodynamics. Pregnancies were observed until delivery. RESULTS: A total of 182 normotensive pregnancies were included. After the evaluation, 54 fetuses were classified as growth restricted, 42 as small for gestational age, and 86 as adequate for gestational age. The fetus with fetal growth restriction had significantly lower umbilical vein diameter (P<.0001), umbilical vein velocity (P=.02), umbilical vein flow (P<.0001), and umbilical vein flow corrected for fetal weight (P<.01) than adequate-for-gestational-age and small-for-gestational-age fetuses. The maternal hemodynamic profile in fetal growth restriction was characterized by elevated systemic vascular resistance and reduced cardiac output. The umbilical vein diameter was positively correlated to maternal cardiac output (rs=0.261), whereas there was a negative correlation between maternal systemic vascular resistance (rs=-0.338) and maternal potential energy-to-kinetic energy ratio (rs=-0267). The fetal umbilical vein time averaged max velocity was positively correlated to maternal cardiac output (rs=0.189) and maternal inotropy index (rs=0.162), whereas there was a negative correlation with maternal systemic vascular resistance (rs=-0.264) and maternal potential energy-to-kinetic energy ratio (rs=-0.171). The fetal umbilical vein flow and the flow corrected for estimated fetal weight were positively correlated with maternal cardiac output (rs=0.339 and rs=0.297) and maternal inotropy index (rs=0.217 and r=0.336), whereas there was a negative correlation between maternal systemic vascular resistance (rs=-0.461 and rs=-0.409) and maternal potential energy-to-kinetic energy ratio (rs=-0.336 and rs=-0.408). CONCLUSION: Maternal and fetal hemodynamic parameters were different in the 3 groups of fetuses: fetal growth restriction, small for gestational age, and adequate for gestational age. Maternal hemodynamic parameters were closely and continuously correlated with fetal hemodynamic features. In particular, a maternal hemodynamic profile with high systemic vascular resistance, low cardiac output, reduced inotropism, and hypodynamic circulation was correlated with a reduced umbilical vein flow and increased umbilical artery pulsatility index. The mother, placenta, and fetus should be considered as a single cardiac-fetal-placental unit. The correlations of systemic vascular resistance, cardiac output, and inotropy index with umbilical artery impedance indicate the key role of these 3 parameters in placental vascular tree development. The umbilical vein flow rate and, therefore, the placental perfusion seems to be influenced not only by these three parameters but also by the maternal cardiovascular kinetic energy.

RESUMEN

The opinion on the mechanisms underlying the pathogenesis of preeclampsia still divides scientists and clinicians. This common complication of pregnancy has long been viewed as a disorder linked primarily to placental dysfunction, which is caused by abnormal trophoblast invasion, however, evidence from the previous two decades has triggered and supported a major shift in viewing preeclampsia as a condition that is caused by inherent maternal cardiovascular dysfunction, perhaps entirely independent of the placenta. In fact, abnormalities in the arterial and cardiac functions are evident from the early subclinical stages of preeclampsia and even before conception. Moving away from simply observing the peripheral blood pressure changes, studies on the central hemodynamics reveal two different mechanisms of cardiovascular dysfunction thought to be reflective of the early-onset and late-onset phenotypes of preeclampsia. More recent evidence identified that the underlying cardiovascular dysfunction in these phenotypes can be categorized according to the presence of coexisting fetal growth restriction instead of according to the gestational period at onset, the former being far more common at early gestational ages. The purpose of this review is to summarize the hemodynamic research observations for the two phenotypes of preeclampsia. We delineate the physiological hemodynamic changes that occur in normal pregnancy and those that are observed with the pathologic processes associated with preeclampsia. From this, we propose how the two phenotypes of preeclampsia could be managed to mitigate or redress the hemodynamic dysfunction, and we consider the implications for future research based on the current evidence. Maternal hemodynamic modifications throughout pregnancy can be recorded with simple-to-use, noninvasive devices in obstetrical settings, which require only basic training. This review includes a brief overview of the methodologies and techniques used to study hemodynamics and arterial function, specifically the noninvasive techniques that have been utilized in preeclampsia research.

RESUMEN

This study reviewed the literature about the diagnosis, antepartum surveillance, and time of delivery of fetuses suspected to be small for gestational age or growth restricted. Several guidelines have been issued by major professional organizations, including the International Society of Ultrasound in Obstetrics and Gynecology and the Society for Maternal-Fetal Medicine. The differences in recommendations, in particular about Doppler velocimetry of the ductus venosus and middle cerebral artery, have created confusion among clinicians, and this review has intended to clarify and highlight the available evidence that is pertinent to clinical management. A fetus who is small for gestational age is frequently defined as one with an estimated fetal weight of <10th percentile. This condition has been considered syndromic and has been frequently attributed to fetal growth restriction, a constitutionally small fetus, congenital infections, chromosomal abnormalities, or genetic conditions. Small for gestational age is not synonymous with fetal growth restriction, which is defined by deceleration of fetal growth determined by a change in fetal growth velocity. An abnormal umbilical artery Doppler pulsatility index reflects an increased impedance to flow in the umbilical circulation and is considered to be an indicator of placental disease. The combined finding of an estimated fetal weight of <10th percentile and abnormal umbilical artery Doppler velocimetry has been widely accepted as indicative of fetal growth restriction. Clinical studies have shown that the gestational age at diagnosis can be used to subclassify suspected fetal growth restriction into early and late, depending on whether the condition is diagnosed before or after 32 weeks of gestation. The early type is associated with umbilical artery Doppler abnormalities, whereas the late type is often associated with a low pulsatility index in the middle cerebral artery. A large randomized clinical trial indicated that in the context of early suspected fetal growth restriction, the combination of computerized cardiotocography and fetal ductus venosus Doppler improves outcomes, such that 95% of surviving infants have a normal neurodevelopmental outcome at 2 years of age. A low middle cerebral artery pulsatility index is associated with an adverse perinatal outcome in late fetal growth restriction; however, there is no evidence supporting its use to determine the time of delivery. Nonetheless, an abnormality in middle cerebral artery Doppler could be valuable to increase the surveillance of the fetus at risk. We propose that fetal size, growth rate, uteroplacental Doppler indices, cardiotocography, and maternal conditions (ie, hypertension) according to gestational age are important factors in optimizing the outcome of suspected fetal growth restriction.

RESUMEN

Pregnancy has an important impact on the thyroid gland and its function. Thyroid activity changes as a consequence of the novel physiological state of pregnancy and requires a complex hormonal and metabolic adaptation, which is possible only in the presence of a perfectly functioning thyroid gland. In fact, thyroid function is crucial for the success of the implantation and the progression of pregnancy. Abnormal thyroid function is very common among childbearing age women, explaining the high incidence of thyroid diseases that occur during pregnancy. Aim of this work is to analyze the adaptive events that characterize the thyroid function during pregnancy, exploring their hormonal, metabolic and molecular mechanisms. Moreover, the interpretation of the laboratory data necessary to monitor the thyroid functioning during normal pregnancy or in the presence of thyroid abnormalities will be discussed.

RESUMEN

AIM: The aim of the study was to evaluate the impact of SARS-CoV-2 vaccination on quality of life, psychological aspect and sexual life in a group of Italian postmenopausal women during the COVID-19 pandemic. METHODS: The study was a prospective, observational analysis of postmenopausal women before and after the COVID-19 vaccination. The population previously answered different questionnaires, such as the Female Sexual Function Index (FSFI), the Female Sexual Distress Scale (FSDS), the 36-Item Short Form Survey (SF-36) and the Hospital Anxiety and Depression Scale (HADS). Twelve weeks after the end of the vaccine cycle, these women were invited to complete the same questionnaires by e-mail to evaluate if vaccination coverage could positively impact the quality of life of postmenopausal women. The Patient Impression of Global Improvement (PGI-I) after three months of treatment was also calculated. RESULTS: A total of 114 patients were reported. The median age was 60.96 (52-66) years. Mean sexual intercourses/month increased from 1.28 ± 1.23 to 4.21 ± 1.80 (p = 0.001). The FSFI increased (19.22 ± 3.31 vs 29.24 ± 4.21, p < 0.0001) and the FSDS decreased significantly (20.12 ± 5.23 vs 9.32 ± 5.55, p < 0.0001) 12 weeks after vaccination coverage. The SF-36 increased from 64.23 ± 11.76 to 82.21 ± 10.24 (p < .0001) and the HADS questionnaire improved significantly from 9.3 ± 2.73 to 5.1 ± 1.34 after the COVID-19 vaccine execution (p<.0001). CONCLUSIONS: The spread of COVID-19 vaccine coverage positively influenced sexual function, quality of life and psychological aspect in postmenopausal women.

RESUMEN

Introduction: The number of pregnancies obtained through in vitro fertilization (IVF) techniques are increasing, and only few studies have investigated hemodynamic variations in women undergoing IVF techniques. The aim of this study was to evaluate the hemodynamic parameters in women undergoing IVF, to assess a possible correlation between hemodynamics and embryo implantation.Methods: 45 normotensive non-obese women, age ≤ 43 years, with idiopathic or tubal infertility, referred to the Reproductive Physiopathology and Andrology Unit, Sandro Pertini Hospital, Rome, during the period 2020/2021, underwent IVF techniques. All women were evaluated with Ultra Sonic Cardiac Output Monitor (USCOM) to detect hemodynamic parameters at two different stages: at the mid-luteal phase, before the beginning of IVF, and at the day of embryo transfer (dET). All demographics and hormonal parameters in both groups were comparable. The hemodynamic parameters were compared between women with a positive ß-HCG test vs. those testing negative.Results: 11 out of 45 (24,5%) women obtained positive ß-HCG test. All demographics and hormonal parameters were comparable in both groups. Women with a positive ß-HCG test showed statistically lower systemic vascular resistance (SVR) at mid-luteal phase (868.61 ± 100.1 vs. 1009 ± 168.4) and dET (818,9 ± 104.5 vs 1038.52 ± 150.82 dynes × s/cm5).Conclusions: Hemodynamic assessment can identify a more favorable pre-pregnancy cardiovascular adaptation. Embryo implantation might be positively influenced by the hemodynamic parameters, e.g. lower SVR, before the beginning of IVF techniques, and during the window of implantation.

RESUMEN

PURPOSE: The aim of the study is to compare maternal hemodynamic adaptations in gestational diabetes (GDM) versus healthy pregnancies. METHODS: A prospective case-control study was conducted, comparing 69 singleton pregnancies with GDM and 128 controls, recruited between September 2018 and April 2019 in Maternal-Fetal Medicine Unit, Careggi University Hospital, Florence, Italy. Hemodynamic assessment by UltraSonic Cardiac Output Monitor (USCOM) was performed in both groups in four gestational age intervals: 17-20 weeks (only in early GDM cases), 26-30 weeks, 32-35 weeks and 36-39 weeks. We evaluated six hemodynamic parameters comparing GDM cases versus controls: cardiac output (CO), cardiac index (CI), stroke volume (SV), total vascular resistance (TVR), inotropy index (INO) and potential to kinetic energy ratio (PKR). RESULTS: GDM group had significantly lower values of CO and SV than controls from the early third trimester (26-30 weeks) until term (p < 0.001). CI is significantly lower in GDM women already at the first evaluation (p = 0.002), whereas TVR and PKR were significantly higher in GDM (p < 0.001). GDM women showed also lower INO values than controls in all assessments. CONCLUSIONS: A hemodynamic maternal maladaptation to pregnancy can be detected in GDM women. The effect of hyperglycemia on vascular system or a poor pre-pregnancy cardiovascular (CV) reserve could explain this hemodynamic maladaptation. The abnormal CV response to pregnancy in GDM women may reveal a predisposition to develop CV disease later in life and might help in identifying patients who need a CV follow-up.

RESUMEN

BACKGROUND: Chronic hypertension complicates around 3% of all pregnancies and is associated with an increased risk for pregnancy complications such as superimposed preeclampsia, fetal growth restriction, preterm delivery, and stillbirth, reaching a rate of complications of up to 25-28%. OBJECTIVE: We performed an echocardiographic study to evaluate pre-pregnancy cardiac geometry and function, along with the hemodynamic features of treated chronic hypertension patients, searching for a possible correlation with the development of feto-maternal complications and with pre-pregnancy therapy. MATERIALS AND METHODS: This was a prospective observational cohort study of 192 consecutive patients receiving treatment for chronic hypertension (calcium channel blockers, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, ß-blockers, α1-adrenoceptor antagonists, and/or diuretics). Patients underwent echocardiography before pregnancy, assessing left ventricular morphology and function, cardiac output, and total vascular resistance. Pre-pregnancy therapy was noted, patients were shifted to α-methyldopa right before pregnancy, and were followed until delivery, noting major early (<34weeks' gestation) and late (≥34 weeks' gestation) complications. Comparisons among the 3 groups (ie, those with no complications, early complications, and late complications) were performed with 1-way analysis of variance with Student-Newman-Keuls correction for multiple comparisons. The Mann-Whitney U test was used for non-normally distributed data. Comparison of proportions was used as appropriate. Receiver operating characteristic curve analysis was used to identify cutoff values of diastolic dysfunction in this population using the E/e' ratio, and separate cutoff of values for total vascular resistance for the prediction of early and late complications of pregnancy. Binary univariate and multivariate logistic regression as well as Cox proportional hazards regression were used to evaluate the possible correlation among angiotensin-converting enzyme inhibitor/angiotensin receptor blocker and/or calcium channel blocker pre-pregnancy therapy, cardiovascular features, and the risk for subsequent early and late complications of pregnancy. RESULTS: Of 192 patients, 141 had no complications, and 51 had a complicated pregnancy (24 had early complications and 27 had late complications). Concentric geometry was more frequent in those women with early versus late and no complications (50% vs 13.5% and 11.1%, respectively; P < .05), whereas eccentric hypertrophy was more represented in women with late versus early and no complications (32% versus 12.5% and 1.4%, respectively; P < .05). The receiver operating characteristic curve showed an E/e' ratio value >7.65 (sensitivity, 59.6%; specificity, 68.6%) as a predictor of subsequent complications of pregnancy, whereas total vascular resistance <1048 (sensitivity, 83.7%; specificity, 55.6%) was predictive for late complications and total vascular resistance >1498 (sensitivity, 87.5%; specificity, 78.0%) for the early complications of pregnancy. Univariate analysis showed that the following parameters were predictive for complications of pregnancy: altered geometry of the left ventricle (odds ratio, 5.94; 95% confidence interval, 2.90-12.19), diastolic dysfunction (odds ratio, 3.22; 95% confidence interval, 1.63-6.37), altered total vascular resistance (odds ratio, 3.52; 95% confidence interval, 1.78-6.97), and pre-pregnancy therapy without calcium channel blockers/angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (odds ratio, 2.73; 95% confidence interval, 1.37-5.42). These parameters, except for altered total vascular resistance, were independent predictors in the multivariate analysis corrected for body mass index, heart rate, parity, and mean arterial pressure. CONCLUSION: Chronic hypertension patients with pre-pregnancy cardiac remodeling and dysfunction more often develop early and late complications of pregnancy. Pre-pregnancy therapy for chronic hypertension patients with calcium channel blockers and/or angiotensin-converting enzyme inhibitors/angiotensin receptor blockers may positively influence cardiac profiles and the outcome of a future pregnancy with a reduced rate of complications.

RESUMEN

The recent demonstration of the effectiveness of low-dose aspirin administered from the first trimester in the prevention of preeclampsia will probably lead to establishing and radicating the "inverted pyramid" screening model for preeclampsia. Such a multiparametric approach for the screening of preeclampsia in the first trimester, albeit highly sensitive in identifying early-onset disease, is poor at screening the forms of preeclampsia occurring close to term. Late-onset preeclampsia is 3 to 6 times more common than early-onset preeclampsia and currently represents the major determinant of maternal morbidity related to hypertensive disorders of the pregnancy. On this ground, we discuss our idea to construct a second "screening checkpoint" in the third trimester with the aim of reassessing the risk of preeclampsia of those women who screened negative in the first trimester. If implemented, the sequential screening model we propose would convert the "inverted pyramid model" into an "arrow model" for the antenatal care of preeclampsia.

RESUMEN

BACKGROUND: Inducing labor by ensuring a good maternal-fetal outcome is a challenge. The aim of the study was to evaluate the success rate, safeness, and time to delivery after the induction of labor (IOL), with the alternately first use of dinoprostone or Foley balloon, in high-risk pregnancy nulliparous women with unfavorable Bishop Score (BS). METHODS: This is a retrospective study of high-risk nulliparous women who underwent the IOL, either with dinoprostone or the Foley balloon method. In the former case, if the labor has not started after dinoprostone removal, oxytocin infusion started. In Foley group, the BS was re-evaluated after Foley removal, and IOL continued with the use of dinoprostone (if BS<6) or oxytocin (if BS>6). Here, too, if no labor occurred after dinoprostone removal, Oxytocin was administered. Delivery mode, fetal and maternal complications were recorded. The time to delivery was tracked. RESULTS: A total of 261 women were enrolled in the study. The CS rate was similar between groups (37.56% vs. 35.93%; P=0.81). Time to delivery was statistically lower in dinoprostone group (26.82h), as opposed to Foley (47.4h) (P<0.0001). Body Mass Index (BMI) of women who underwent Cesarean section (CS) was significantly higher than women who gave birth by vaginal delivery (VD), 26.80 vs. 27.40, P=0.012. CONCLUSIONS: IOL in high-risk pregnancy nulliparous women resulted in equal rate of CS between the two groups. Dinoprostone first use resulted in a shorter time to delivery, with no maternal-fetal side effects. There is then no need to prolong IOL and raise maternal stress, as this will not yield better outcomes.

RESUMEN

INTRODUCTION: To evaluate the maternal and fetal hemodynamic effects of treatment with a nitric oxide donor and oral fluid in pregnancies complicated by fetal growth restriction. METHODS: 30 normotensive participants with early fetal growth restriction were enrolled. 15 participants were treated until delivery with transdermal glyceryl trinitrate and oral fluid intake (Treated group), and 15 comprised the untreated group. All women underwent non-invasive assessment of fetal and maternal hemodynamics and repeat evaluation 2 weeks later. RESULTS: In the treated group, maternal hemodynamics improved significantly after two weeks of therapy compared to untreated participants. Fetal hemodynamics in the treated group showed an increase in umbilical vein diameter by 18.87 % (p < 0.01), in umbilical vein blood flow by 48.16 % (p < 0.01) and in umbilical vein blood flow corrected for estimated fetal weight by 30.03 % (p < 0.01). In the untreated group, the characteristics of the umbilical vein were unchanged compared to baseline. At the same time, the cerebro-placental ratio increased in the treated group, while it was reduced in the untreated group, compared to baseline values. The treated group showed a higher birthweight centile (p = 0.03) and a lower preeclampsia rate (p = 0.04) compared to the untreated group. DISCUSSION: The combined therapeutic approach with nitric oxide donor and oral fluid intake in fetal growth restriction improves maternal hemodynamics, which becomes more hyperdynamic (volume-dominant). At the same time, in the fetal circuit, umbilical vein flow increased and fetal brain sparing improved. Although a modest sample size, there was less preeclampsia and a higher birthweight suggesting beneficial maternal and fetal characteristics of treatment.

RESUMEN

A new Italian intersociety position statement on the prevention of ophthalmia neonatorum was published in 2023. In this document, attention was paid to the indications for the screening of gonococcal and chlamydial infections during pregnancy according to the international and national guidelines for the prevention of sexually transmitted infections (STIs). We conducted an observational retrospective study to assess whether the current guidelines for the prevention of STIs are being followed correctly. From February to August 2022, 2507 women nearing childbirth were enrolled. Among them, 42.4% received a swab for Chlamydia and only 0.5% for gonococcus. Concerning the geographical area of origin, most of the screened women came from Western Europe. None of the women who received gonococcal swabs and only 105 women out of 1062 screened for Chlamydia were under 25 years of age. Overall, only seven swabs were positive for Chlamydia, while none were positive for gonococcus. Concerning the age, geographical area of origin, and medical history of the women with a positive screening for Chlamydia, all were over 25 years old, six were from Western Europe, one was from South America, and none had other STIs. Although monocentric in nature, this study shows that the guidelines are not being followed correctly.

RESUMEN

BACKGROUND: The aim of this study was to analyze how antepartum pelvic floor muscle training (PFMT) plus perineal massage associated with postpartum PFMT have a significant impact on pelvic floor health during pregnancy and after delivery. METHODS: One thousand two hundred thirty-three women were enrolled from January 2019 to December 2021. They were divided into two groups: 786 women underwent postpartum PFMT only, 447 women experienced both prepartum perineal massage and PFMT and postpartum PFMT. The primary endpoint was to evaluate prepartum perineal massage and PFMT's impact on delivery. The second endpoint was the evaluation of Quality of Life and sexual function at 3- and 12-months follow-up after delivery. RESULTS: Women who underwent prepartum PFMT experienced significantly lower percentage of episiotomy, high-grade obstetric tear or instrumental delivery and higher percentage of intact perineum. Furthermore, prepartum PFMT appeared to improve sexual function at 3 months follow-up, and it was associated with an earlier first sexual intercourse after childbirth. The incidence of stress urinary incontinence was significantly higher in women who experienced PFMT only in postpartum, both at 3- and 12-months follow-up, while the other examined clinical parameters did not show a significant difference. CONCLUSIONS: Prepartum PFMT has a role in preventing obstetric traumas and on improving Sexual Function and Quality of Live in the immediate postpartum. Moreover, prepartum PFMT in association with postpartum PFMT reduces the incidence of stress urinary incontinence in a higher percentage than postpartum PFMT only.

RESUMEN

OBJECTIVE: To assess the prevalence of adenomyosis at pathologic examination, and its association with obstetric complications, peripartum maternal clinical characteristics and neonatal birth weight in patients undergoing postpartum hysterectomy due to postpartum hemorrhage (PPH). METHODS: A multicenter, observational, retrospective, cohort study was carried out including all women who underwent postpartum hysterectomy due to PPH at gestational week 23+0 or later, between January 2010 and May 2023. Patients were categorized into two groups based on the presence of adenomyosis at pathologic examination, and were compared for obstetric complications, peripartum maternal clinical characteristics, and neonatal birth weight. RESULTS: The histologically-based prevalence of adenomyosis in patients undergoing postpartum hysterectomy due to PPH was 39.4%. Adenomyosis was associated with a longer hospitalization time (regression coefficient: 4.43 days, 95% CI: 0.34-8.52, P = 0.034) and a higher risk of hypertensive disorders (OR: 5.82, 95% CI: 1.38-24.46, P = 0.016), threatened preterm labor (OR: 3.34, 95% CI: 1.08-10.31, P = 0.036), urgent/emergency C-section (OR: 24.15, 95% CI: 2.60-223.96, P = 0.005), postpartum maternal complications (OR: 4.96, 95% CI: 1.48-16.67, P = 0.012), maternal intensive care unit admission (OR: 3.56, 95% CI: 1.05-12.05, P = 0.041), and low birth weight neonates (OR: 3.8, 95% CI: 1.32-11.02, P = 0.013). CONCLUSION: In patients undergoing postpartum hysterectomy due to PPH, adenomyosis is a highly prevalent condition among, and is associated with adverse obstetric, maternal, and neonatal outcomes.
