ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2022; 60:604-611. [PMID: 35656849 PMCID: PMC9828663 DOI: 10.1002/uog.24967] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/06/2022] [Revised: 05/02/2022] [Accepted: 05/25/2022] [Indexed: 05/27/2023]
Abstract
OBJECTIVES To evaluate and compare the diagnostic test accuracy (DTA) of three-dimensional transvaginal ultrasound (3D-TVS) and magnetic resonance imaging (MRI) for deep myometrial infiltration (DMI) and cervical invasion for preoperative staging and surgery planning in patients with endometrial cancer (EC). METHODS This systematic review and meta-analysis investigated the DTA of MRI and 3D-TVS for DMI and cervical invasion in patients with EC. A literature search was performed using MEDLINE, Scopus, EMBASE, ScienceDirect, The Cochrane library, ClinicalTrials.gov, Cochrane Central Register of Controlled Trials, EU Clinical Trials Register and World Health Organization International Clinical Trials Registry Platform to identify relevant studies published between January 2000 and December 2021. Study quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool. RESULTS Five studies, including a total of 450 patients, were included in the systematic review. All five studies compared the DTA of 3D-TVS vs MRI for DMI, and three studies compared the DTA of 3D-TVS vs MRI for cervical invasion. Pooled sensitivity, positive likelihood ratio and negative likelihood ratio for detecting DMI using 3D-TVS were 77% (95% CI, 66-85%), 4.57 and 0.31, respectively. The respective values for detecting DMI on MRI were 80% (95% CI, 73-86%), 4.22 and 0.24. Bivariate metaregression indicated a similar DTA of 3D-TVS and MRI (P = 0.80) for the correct identification of DMI. Pooled ln diagnostic odds ratio for detecting cervical invasion was 3.11 (95% CI, 2.09-4.14) for 3D-TVS and 2.36 (95% CI, 0.90-3.83) for MRI. The risk of bias was low for most of the four domains assessed in QUADAS-2. CONCLUSION 3D-TVS demonstrated good diagnostic accuracy in terms of sensitivity and specificity for the evaluation of DMI and cervical invasion, with results comparable with those of MRI. Thus, we confirmed the potential role of 3D-TVS in the preoperative staging and surgery planning in patients with EC. © 2022 The Authors.

Abstract
Abstract
Study question
How does the septate uterus and his metroplasty influence pregnancy rate (PR), live birth rate (LBR), spontaneous abortion rates (SA) and preterm labour rates (PL)?
Summary answer
Uterine septum is associated with a poor reproductive outcome. Metroplasty reduce the rate of SA but non-conclusive evidence can be extrapolated about PR and PL.
What is known already
Different studies evaluated the correlation between uterine septum and reproductive outcomes. On one hand, studies reported its association with poor obstetrics outcomes. On the other hand, recent studies raised doubts about the effectiveness of septum metroplasty to improve reproductive outcomes, although recent position papers continue to propose metroplasty in patients with a septate uterus and a history of infertility or miscarriages. Debate is still ongoing on reproductive outcomes of uterine septum on infertile patients and especially on patients with recurrent miscarriage, leading to an unanswered question whether or not these women should be treated.
Study design, size, duration
Systematic review and meta-analysis of published studies that evaluated the clinical impact of uterine septum and its metroplasty on reproductive and obstetrics outcomes. The meta-analysis included study with infertile patients or patients with a history of recurrent miscarriage.
Searches were conducted using the following search terms: uterine septum, septate uterus, metroplasty, pregnancy rate, live birth rate, spontaneous miscarriage, infertility, preterm delivery. Primary outcomes were PR and LBR. Secondary outcomes were SA and PL.
Participants/materials, setting, methods
The meta-analysis was written following the PRISMA guidelines. Fifty-nine full-text articles were preselected based on title and abstract. Endpoints were evaluated in three subgroups: 1) infertile/recurrent miscarriage patients with septum versus no septum 2) infertile/recurrent miscarriage patients with treated versus untreated septum 3) infertile/recurrent miscarriage patients before-after septum removal. Odds-ratios (OR) with 95% confidence intervals (CI) were calculated for outcome measures. Random-effect meta-analysis was performed and a p-value less than 0.05 was considered statistically significant.
Main results and the role of chance
Data from 37 articles were extracted. In the first subgroup (10 studies), a lower PR and LBR were associated with septate uterus vs. controls, respectively (OR 0.39, 95% CI 0.26 to 0.58; p < 0.000; low-heterogeneity and OR 0.21, 95% CI 0.12 to 0.39; p < 0.0001; small-heterogeneity) and a higher proportion of SA and PL was associated with septate uterus vs. controls, respectively (OR 4.17, 95% CI 2.83 to 6.15; p < 0.000; moderate-heterogeneity and OR 2.18, 95% CI 1.27 to 3.76; p = 0.005; low-heterogeneity). In the second subgroup (8 studies), PR and PL were not different in removed vs. unremoved septum, respectively (OR 1.10, 95% CI 0.49 to 2.49; p = 0.82; moderate heterogeneity and OR 0.44, 95% CI 0.18 to 1.08; p = 0.08;low-heterogeneity) and a lower proportion of SA was associated with removed vs. unremoved septum (OR 0.40, 95% CI 0.17 to 0.95; p = 0.001; substantial-heterogeneity). In the third subgroup (19 studies), the proportion of LBR was higher after the removal of septum (OR 49.58, 95% CI 29.93 to 82.13; p < 0.0001; moderate-heterogeneity) and the proportion of SA and PL was lower after the removal of septum, respectively (OR 0.02, 95% CI 0.02 to 0.04; p < 0.000; moderate-heterogeneity and OR 0.05, 95% CI 0.03 to 0.08; p = <0.000; low-heterogeneity).
Limitations, reasons for caution
The present meta-analysis is limited by the observational design of included studies because, in literature, there are no prospective randomized controlled trials (RCTs). In the second and third subgroup of analysis clinical heterogeneity within and between studies represents another limitation.
Wider implications of the findings
The results of this meta-analysis confirm the detrimental effect of uterine septum on PR, LBR, SA and PL. Its treatment seems to reduce the rate of SA. Metroplasty should still be considered as good clinical practice in patients with a history of infertility and recurrent abortion.

Abstract
Hypoxic-ischemic encephalopathy, also referred as HIE, is a type of brain injury or damage that is caused by a lack of oxygen to the brain during neonatal period. The incidence is approximately 1.5 cases per 1000 live births in developed countries. In low and middle-income countries, the incidence is much higher (10‒20 per 1000 live births). The treatment for neonatal HIE is hypothermia that is only partially effective (not more than 50% of the neonates treated achieve an improved outcome). HIE pathophysiology involves oxidative stress, mitochondrial energy production failure, glutaminergic excitotoxicity, and apoptosis. So, in the last years, many studies have focused on peptides that act somewhere in the pathway activated by severe anoxic injury leading to HIE. This review describes the pathophysiology of perinatal HIE and the mechanisms that could be the target of innovative HIE treatments.

Abstract
Endometrial glands represent an important source of nutrients for the conceptus during the first trimester. Their secretions are enriched with carbohydrates, and glycogen accumulates within the syncytiotrophoblast of the placenta. It has been assumed that fetal and placental metabolism follow adult pathways, although it is now appreciated that early development occurs in a low-oxygen environment. In past decades, a novel family of putative insulin mediators, inositol phosphoglycans (IPGs), was discovered. These molecules act as allosteric activators and/or inhibitors of enzymes and transduction proteins involved in the control of cell signalling and metabolic pathways, and determine the specificity of responses after activation of the insulin receptor. One member, IPG P-type, activates pyruvate dehydrogenase phosphatase (PDH-Pase), glycogen synthase phosphatase, and glycerol-3-phosphate acyltransferase. Activation of key phosphatases play a major role in the regulation of glucose disposal by oxidative metabolism via PDH, and the non-oxidative storage by glycogen synthesis, both pathways classically known to be regulated by insulin. High concentrations of IPG P-type in amniotic fluid suggest a role in the regulation of carbohydrate metabolism in the fetal-placental unit. Glycogen accumulation in the syncytiotrophoblast also occurs in preeclamptic pregnancies, and is consistently associated with higher placental levels of IPG P-type. Here, we explore the relationship between nutrients provided by the endometrial glands during early pregnancy, IPG P-type and fetal metabolic requirements. We also discuss whether a disconnect between the placental/fetal metabolic state and oxygen tension could lead to a preeclamptic-type syndrome via leakage of Warburg/IPG mediators into the maternal circulation.

Abstract
AIM Severe endometriosis represents one of the most challenging clinical and surgical cases in gynecology. Preoperative assessment of the extension of the disease is of key relevance to opt for medical or surgical therapy and, sometimes, to plan a multidisciplinary approach. METHODS A systematic diagnostic approach is proposed and evaluated in a tertiary referral centre. It is based on an initial clinical evaluation and a second level ultrasound of the pelvis. Further exams, whenever required, have to be aimed at demonstrating specific involvements of organs other than ovaries and peritoneum such as bowel, urinary tract and nerves. RESULTS The application of the proposed protocol has led to a reduction of the number of non-radical surgical procedures due to incomplete consent associated with missed diagnosis over the years (P<0.001). CONCLUSION Our findings support the efficacy of a systematic diagnostic approach to endometriosis. This allows a correct planning of therapy with a multidisciplinary approach when necessary.

Abstract
BACKGROUND The purpose of the study was to determine the influence of bowel endometriosis on fertility, and to study whether its removal improves fecundity in women with endometriosis-associated infertility. METHODS Three groups of infertile patients were included in the study. Group A (60 women) consisted of patients who underwent surgery for endometriosis with colorectal segmental resection. In group B, 40 patients with evidence of bowel endometriosis underwent endometriosis removal without bowel resection. Group C consisted of 55 women who underwent surgery for moderate or severe endometriosis with at least one endometrioma and deep infiltrating endometriosis but without bowel involvement. The women were clinically evaluated before laparoscopy and then at 1 month, at 6 months and at each year up to 4 years after surgery. Main outcome measures were surgical complications as well as post-operative pregnancy rate, time to conception and monthly fecundity rate. RESULTS The monthly fecundity rates (MFR) in groups A, B and C were 2.3, 0.84 and 3.95%, respectively. The difference in the MFR between groups was significant (P < 0.05). CONCLUSIONS The presence of bowel infiltration by endometriosis seems to negatively influence the reproductive outcome in women with endometriosis-associated infertility. The complete removal of endometriosis with bowel segmental resection seems to offer better results in terms of post-operative fertility.

Social determinants of the increasing caesarean section rate in Italy. MINERVA GINECOLOGICA 2008; 60:115-120. [PMID: 18487961] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 05/26/2023]
Abstract
AIM Consistent modifications of socio-economic factors may represent crucial non-clinical determinants for the rising rate of caesarean section among primiparae. This increasing trend has been reported in many countries and its relationship with social modifications is widely accepted, though poorly supported by published data. METHODS Population-based social and economic data were analyzed between two study periods 30 years apart (1971 vs 2001). RESULTS The number of births dropped dramatically within the study period (about -40%). Italian women tend to delay childbearing (25.1 vs 28.8 years of age at first delivery) to pursue a career and a later marriage and motherhood lead to a contraction of the number of members of the family. Older mothers are at higher risk of caesarean (treble over 40 years of age), especially those with high career position. Health expenditures increased significantly between 1971 and 2001. A progressive contraction of the number of women in reproductive age is expected in the next 50 years in Italy. CONCLUSION Many determinants are involved in the choice of a caesarean section and most of these are not strictly medical. The rapidly mounting number of legal claims may indeed lead to defensive practices. Given these data, a reduction of caesarean section rate seems unlikely to be achieved at present.

Abstract
OBJECTIVE The accuracy of current formulae for the sonographic estimation of fetal weight (EFW) is compromised by significant intra- and interobserver variability of biometrical measurements, particularly circumferences. The aim of this study was to assess the reliability of the linear measurement of mid-thigh soft-tissue thickness (STT) and to derive a novel formula for EFW. METHODS This was a prospective study involving 388 singleton uncomplicated pregnancies. There were three consecutive phases: (1) to verify the relationship between STT and birth weight, (2) to derive a novel formula for EFW using femur length and STT only, and (3) to test the accuracy of the new equation. Only the 290 patients who delivered within 48 h of measurement were considered for the analysis. A comparison with other formulae was performed. RESULTS STT was significantly correlated with both abdominal circumference and birth weight (r(2) = 0.36 and 0.46, respectively; P < 0.001). Both intra- and interobserver variability were satisfactory (0.44 +/- 0.27 and 0.57 +/- 0.35 mm, respectively). The equation for EFW was developed using multiple stepwise regression analysis (EFW = - 1687.47 + (54.1 x femur length) + (76.68 x STT)) and tested prospectively on 69 patients. The new formula yielded results (r = 0.79) that were slightly better in accuracy than two other published equations, and had an absolute mean error of < 15% in 97% of cases. CONCLUSIONS Our findings confirm the potential of the linear measurement of mid-thigh STT as a valuable parameter for the sonographic assessment of fetal growth and EFW. Our new equation is apparently at least as reliable as the most widely used formulae for EFW.

Abstract
OBJECTIVE The mechanisms underlying insulin resistance during normal pregnancy, and its further exacerbation in pregnancies complicated by gestational diabetes mellitus (GDM), are generally unknown. Inositolphosphoglycan P-type (P-IPG), a putative second messenger of insulin, correlates with the degree of insulin resistance in diabetic subjects. An increase during normal pregnancy, in maternal and fetal compartments, has recently been reported. METHODS A cross-sectional study was carried out in 48 women with GDM and 23 healthy pregnant women. Urinary levels of P-IPG were assessed spectrophotometrically by the activation of pyruvate dehydrogenase phosphatase in urinary specimens and correlated with clinical parameters. RESULTS Urinary excretion of P-IPG was higher in GDM than in control women (312.1 +/- 151.0 vs. 210.6 +/- 82.7 nmol NADH/min/mg creatinine, P < 0.01) with values increasing throughout pregnancy in control subjects (r2 = 0.34, P < 0.01). P-IPG correlated with blood glucose levels (r(2) = 0.39, P < 0.01 for postprandial glycaemia and r2 = 0.18 P < 0.01 for mean glycaemia) and birthweight in the diabetic group (r2 = 0.14, P < 0.01). CONCLUSIONS Increased P-IPG urinary excretion occurs in GDM and positively correlates with blood glucose levels. P-IPG may play a role in maternal glycaemic control and, possibly, fetal growth in GDM.

Abstract
OBJECTIVE To assess differences in adipose deposition in fetuses from normal pregnancies and women with diabetes. RESEARCH DESIGN AND METHODS The study group consisted of 15 well controlled insulin-dependent women with diabetes and 16 controls with a normal glucose. Ultrasound measurements were taken of subcuticular tissue thickness at the abdominal and suprascapular level at 31 and 37 weeks gestation. Triceps and subscapular skinfold thickness were also measured at birth. RESULTS Gestational age at delivery and birthweights were not significantly different. At 31 weeks, fasting glucose levels were 5.0 +/- 1 mmol/l for diabetic vs. 3.3 +/- 0.3 mmol/l for controls (P < 0.01), post-prandial 5.6 +/- 0.4 vs. 5.1 +/- 0.3 mmol/l (P < 0.01). At 37 weeks, they were 4.6 +/- 0.2 mmol/l vs. 3.8 +/- 1.1 mmol/l (P < 0.01) and 6.0 +/- 0.6 mmol/l vs. 5.3 +/- 0.3 mmol/l (P < 0.01). Abdominal and suprascapular subcuticular thickness were 4.4 +/- 0.1 mm vs. 3.7 +/- 0.1 mm (P < 0.05) and 4.3 +/- 0.2 mm vs. 3.5 +/- 0.2 mm (P < 0.05) at 31; 5.6 +/- 0.2 mm vs. 4.8 +/- 0.1 mm (P < 0.05) and 5.4 +/- 0.2 mm vs. 4.4 +/- 0.1 mm (P < 0.05) at 37 weeks. At birth, triceps and suprascapular skinfolds were 4.7 +/- 0.1 mm vs. 4.1 +/- 0.1 mm (P < 0.05) and 4.7 +/- 0.2 mm vs. 3.8 +/- 0.1 mm (P < 0.01). CONCLUSION Adipose tissue disposition is increased in fetuses of women with well-controlled diabetes. This may be a reflection of higher maternal glucose levels in these women and may explain why even well-controlled diabetic pregnancies are at risk of macrosomia.

Abstract
AIM Prostaglandin analogues provide an effective method for induction of abortion in the second trimester of pregnancy. The clinical outcome and the risk of complications were evaluated in a group of women having a medical termination of pregnancy with gemeprost. METHODS Three-hundred and six women undergoing second trimester termination of pregnancy, between January 1998 and July 2002 in our center, were studied. All women were given 1 mg vaginal gemeprost every 3 h up to a maximum of 3 doses in the first 24 hours. If the abortion did not occur within the first 24 hours after initiation of treatment, they were given a 2(nd) course of gemeprost. Outcome measures included failure of the 1st course of gemeprost, length of hospital stay after expulsion of conceptus, heavy blood loss with or without necessity of uterine packing or blood transfusion, and failure of induction. RESULTS There was a significant difference, with better results in women with previous deliveries (vaginal or abdominal), as to the failure to abort after the 1(st) course of PG (P<0.01). Length of hospital stay, complications and failure of induction were independent from parity. Twelve (3.9%) women failed to abort with gemeprost and required other methods for abortion. CONCLUSIONS The study confirms the efficacy of gemeprost for mid-trimester termination of pregnancy, although it is a risky and costly procedure, requiring hospitalisation and is associated with higher complication rate than the first trimester surgical abortion.

Abstract
OBJECTIVE To evaluate the efficacy of ultra short-term antimicrobial prophylaxis with ceftazidime in patients undergoing radical gynecologic surgery. PATIENTS AND METHODS Two hundred patients undergoing surgery for a malignant disease of the female genital tract were enrolled in a prospective trial to receive 2.0 g ceftazidime as a single dose, 30 minutes before induction of anaesthesia. After surgery, each patient was assessed to confirm febrile status and the presence of infections at the surgical site, urinary tract and respiratory tract. RESULTS Postoperative morbidity occurred in 23 patients (11, 5%). Ten patients (5%) developed febrile morbidity, five (2, 5%) vaginal cuff infections, four asymptomatic bacteriuria and two each wound infiltration and urinary tract infection. Twelve patients had microbiological evidence of infection and Staphylococccus aureus was the most common pathogen isolated. Univariate analysis demonstrated that pre-existing systemic disease, extensive blood loss (more than 500 ml) and long duration of surgery (more than 150 minutes) were the only factors associated with a significant increase in postoperative febrile morbidity. CONCLUSIONS Ultra short-term antimicrobial prophylaxis with ceftazidime is safe and effective in patients undergoing surgery for gynecologic cancer.

Abstract
OBJECT To assess whether transvaginal ultrasound is helpful in predicting the post-term onset of labor (> or = 1 weeks). SETTING Antenatal clinic of a University hospital and referral center. SUBJECT AND MEHODS: One hundred and twenty singleton uncomplicated pregnancies in primiparous women were enrolled at 37 weeks of gestation. Ultrasound examination of the cervical length by a transvaginal probe was performed at recruitment and at weekly intervals until 40 completed weeks. Subjects were divided into Group A (those with spontaneous onset of labor < or = 1 completed weeks) and Group B (those not in labor by that date). RESULTS Eighty women delivered < or = 41 completed weeks, forty were not in labor by that date. The cervix was significantly shorter at 39 and 40 weeks in group A, but no particular cervical length was predictive of post-term delivery. DISCUSSION There is a significant difference in cervical length in women delivering at term compared with those due to have a post-term delivery. This difference is significant from 39 weeks of gestation onwards. We speculate that targeted transvaginal ultrasound may be useful in predicting the post-term onset of labor and possibly in assisting its active management.

Abstract
The insulin-like growth factors (IGFs) and their receptors are implicated in pre- and postnatal growth and development. It is believed that the alteration in their activity may contribute to intrauterine growth restriction (IUGR). The aim of this experimental study was to relate some metabolic alterations, involving insulin-like growth factor pathway, in the placenta of pregnancies complicated by intrauterine growth restriction. Placental samples were obtained from six uncomplicated pregnancies and four pregnancies complicated by IUGR. These samples were then stained by immunohistochemical technique, using monoclonal antibodies. Our data have not shown a significant difference in the IR, the Shc isoforms and Akt levels between normal and IUGR placentas. The IUGR placentas had significantly lower levels of IRS-2 expression and higher levels of p85 transcription. IGF-I receptor binds to its ligand and activates two intracellular processes mainly a Shc-mediated pro-mitotic pathway and an anti-apoptotic pathway mediated by IRS and Akt. The diminished activity of one of the two pathways may alter the mitosis/apoptosis balance. Because of the low number of samples and the knowledge about the enzymatic pathways, we have not been able to associate our data to any biological consequence. We can only demonstrate that the enzymatic differences between IUGR and controls tend to the pro-apoptotic processes. It seems to be an other in vivo aspect in favour of the placental role in the IUGR pathogenesis.

Abstract
OBJECTIVE To evaluate the perception of "Defensive Medicine" by hospital based obstetricians and the influence of this attitude on the choice of cesarean delivery. SUBJECTS AND METHODS Questionnaire sent by mail to a sample (76) of obstetricians of general district, teaching and university hospitals in a region of southern Italy (Puglia). Doctors were selected as the head, the most senior and the most junior specialist of each department. Independent variables of the study were considered as demographic data of the subjects, years of service, interest in private practice, size of the hospital, background cesarean section rate, personal and site of work exposure to legal claims. Outcome measures were experience and confidence in training for operative vaginal and breech delivery, use of the partogram in labor, opinion about a trial of labor after a previous cesarean section and about cesarean section on request, personal perception of defensive medicine. Univariate and multivariate analysis of data were performed. RESULTS The response rate was 83%. According to our data, seniority in service meant confidence in and request of more teaching of obstetrics manoeuvres, size of hospitals was positively related to a more rationale approach of the diagnosis of dystocia, heads of units were keener to accept the patient's wish for a cesarean section. Doctors with large private practices were less likely to be sued and the perception of legal pressure was directly related to the rate of cesarean section in each unit. DISCUSSION Defensive Medicine is a reality that encompasses all categories of doctors in this survey. The only differences were in the rate of perception of legal pressure. We believe that residential programs should be modified in order to improve specialists' understanding of malpractice problems and that the patient-doctor relationship should be ameliorated in public hospitals.
