Prevalence, Outcome, and Prevention of Congenital Cytomegalovirus Infection in Neonates Born to Women With Preconception Immunity (CHILd Study).

BACKGROUND: Human cytomegalovirus (HCMV) is the leading infectious cause of congenital disabilities. We designed a prospective study to investigate the rate, outcome, and risk factors of congenital CMV (cCMV) infection in neonates born to immune women, and the potential need and effectiveness of hygiene recommendations in this population. METHODS: The study was composed of 2 sequential parts: an epidemiology (part 1) and a prevention (part 2) study. Performance of part 2 depended upon a cCMV rate >0.4%. Women enrolled in part 1 did not receive hygiene recommendations. Newborns were screened by HCMV DNA testing in saliva and cCMV was confirmed by urine testing. RESULTS: Saliva swabs were positive for HCMV DNA in 45/9661 newborns and cCMV was confirmed in 18 cases. The rate of cCMV was .19% (95% confidence interval [CI]: .11-.29%), and 3 out of 18 infants with cCMV had symptoms of CMV at birth. Age, nationality, occupation, and contact with children were similar between mothers of infected and noninfected newborns. Twin pregnancy (odds ratio [OR]: 7.2; 95% CI: 1.7-32.2; P = .037) and maternal medical conditions (OR: 3.9; 95% CI: 1.5-10.1; P = .003) appeared associated with cCMV. Given the rate of cCMV was lower than expected, the prevention part of the study was cancelled. CONCLUSIONS: Newborns from women with preconception immunity have a low rate of cCMV, which appears to be mostly due to reactivation of the latent virus. Therefore, serological screening in childbearing age would be pivotal to identify HCMV-seropositive women, whose newborns have a low risk of cCMV.

Endometriosis-related spontaneous hemoperitoneum in pregnancy: A case series.

Endometriosis can be associated with adverse pregnancy outcomes. We report six cases of endometriosis-related spontaneous hemoperitoneum diagnosed in pregnant and postpartum women over 13 years. Spontaneous hemoperitoneum in pregnancy mainly occurred in the second half of gestation. All women presented with acute abdominal pain; four of them needed an emergent surgery, two were managed expectantly. The median estimated blood loss was 4250 ml, four women required massive transfusion. Three out of six women had a known history of endometriosis, all of them had histologically confirmed endometriosis after surgery. No maternal or perinatal deaths occurred. In one case, reticence to perform a computed tomography scan led to delayed diagnosis. Since delay can lead to lethal consequences, high levels of suspicion for spontaneous hemoperitoneum should be maintained in cases of severe abdominal pain, even with a woman's negative history of endometriosis. Improved knowledge and regular interdisciplinary meetings are pivotal to ameliorate outcomes.

Scientometric analysis and literature synthesis of 60 years of science on the Atlantic goliath grouper (Epinephelus itajara).

Here, the authors investigate the evolution of scientific literature on the Atlantic goliath grouper (Epinephelus itajara), the largest grouper species in the Atlantic. This species was considered threatened according to the IUCN for nearly three decades due to overfishing and has been protected from fishing in a large part of its range. For the purpose of evaluating the scientific production on an endangered species banned from fishing, the authors present a scientometry and synthesis review analysing the literature produced in the timeline and the content of their studies. To this end, they set up an almost 60-year literary database through the Scopus, Web of Science and Google Scholar platforms. They analyse the publication and knowledge area patterns over the time in the world and in Brazil. They also feature the main areas, locations, ecosystems and types of those research studies and briefly describe the main records found in each decade. An increase in the number of publications was observed from the 1990s onwards worldwide, and particularly in Brazil from the 2000s, coinciding with the pioneering legislations for species protection. Most of the studies were classified within ecology and conservation and took place in countries that implemented moratoriums and had extensive areas of mangroves. Thus, fishing moratorium, classification as endangered, mangroves distribution and conservation all play a role in the studies distribution and contribute positively to the knowledge, as well as support conservation strategies for the species and its ecosystems of occurrence.

Development and validation of a predictive model to identify the active phase of labor.

BACKGROUND: The diagnosis of the active phase of labor is a crucial clinical decision, thus requiring an accurate assessment. This study aimed to build and to validate a predictive model, based on maternal signs and symptoms to identify a cervical dilatation ≥4 cm. METHODS: A prospective study was conducted from May to September 2018 in a II Level Maternity Unit (development data), and from May to September 2019 in a I Level Maternity Unit (validation data). Women with singleton, term pregnancy, cephalic presentation and presence of contractions were consecutively enrolled during the initial assessment to diagnose the stage of labor. Women < 18 years old, with language barrier or induction of labor were excluded. A nomogram for the calculation of the predictions of cervical dilatation ≥4 cm on the ground of 11 maternal signs and symptoms was obtained from a multivariate logistic model. The predictive performance of the model was investigated by internal and external validation. RESULTS: A total of 288 assessments were analyzed. All maternal signs and symptoms showed a significant impact on increasing the probability of cervical dilatation ≥4 cm. In the final logistic model, "Rhythm" (OR 6.26), "Duration" (OR 8.15) of contractions and "Show" (OR 4.29) confirmed their significance while, unexpectedly, "Frequency" of contractions had no impact. The area under the ROC curve in the model of the uterine activity was 0.865 (development data) and 0.927 (validation data), with an increment to 0.905 and 0.956, respectively, when adding maternal signs. The Brier Score error in the model of the uterine activity was 0.140 (development data) and 0.097 (validation data), with a decrement to 0.121 and 0.092, respectively, when adding maternal signs. CONCLUSION: Our predictive model showed a good performance. The introduction of a non-invasive tool might assist midwives in the decision-making process, avoiding interventions and thus offering an evidenced-base care.

Screening for Low-Tract Genital Infections in Women with Threatened Preterm Labor: Which Role?

OBJECTIVES: The aim of this study was to evaluate the possible relationship between cultural specimens and preterm birth in women admitted for threatened preterm labor. Preterm birth is the leading cause of neonatal mortality and antenatal hospitalization; several risk factors including intrauterine infections have been identified, but its real causes remain poorly understood. DESIGN: This is a retrospective, multicenter, cohort study including 250 women admitted for threatened preterm labor. Methods, Participants/Materials, Setting: All women admitted for threatened preterm labor, i.e., presenting with cervical changes and uterine activity before 37 weeks at the obstetrics unit of the hospitals of Modena, Monza, Carate, and Vimercate were included in the study. We excluded twin pregnancies and cases with preterm premature rupture of membranes at admission. Data about maternal history, pregnancy complications, cervical length, vaginal swabs, and urine culture at admission and gestational age at delivery were collected from clinical records in order to compare the incidence of preterm birth according to some known risk factors, cervical length, and microbiological test at admission. RESULTS: 250 women were included in the study; preterm birth at less than 37 weeks occurred in 44.4% women admitted for threatened preterm labor. The incidence of preterm birth was not different between those with a positive or a negative vaginal swab (48.3 vs. 38.4%, p = 0.22) or positive versus negative urine culture (31.8 vs. 42.1%, p = 0.23) at admission. A shorter cervical length at admission was found in women with subsequent preterm birth (17 vs. 19.5 mm, p = 0.03). Cervical length <15 mm (OR 1.82, 95% CI: 1.03-3.23, p = 0.039) predicted the risk of preterm birth. Furthermore, only the history of a previous preterm birth (p = 0.02) and a previous uterine curettage (p = 0.045) was associated with preterm birth. LIMITATIONS: The observational and retrospective nature of the study and its small sample size are important limitations of the study. Moreover, women were not systematically or randomly assigned to the screening for vaginal or urinary infections. CONCLUSIONS: There is no evidence that the search for vaginal or urinary infections in women admitted for threatened preterm labor is helpful to identify those at increased risk of preterm birth. Although several studies have explored the role of screening for bacterial vaginosis in asymptomatic women and some studies evaluated vaginal or urinary infections in women with preterm birth, none of them focused on the possible role of microbiological specimens as a predictive tool in women admitted for threatened PTL. No association was found in our study, but prospective randomized controlled trials are required to confirm the results of this observation.

Misleading meta-analyses of observational studies may generate unjustified alarms: The case of medications for nausea and vomiting in pregnancy.

OBJECTIVES: Because observational studies often use imperfect measurements, results are prone to misclassification errors. We used as a motivating example the possible teratogenic risks of antiemetic agents in pregnancy since a large observational study recently showed that first-trimester exposure to doxylamine-pyridoxine was associated with significantly increased risk of congenital malformations as a whole, as well as central nervous system defects, and previous observational studies did not show such associations. A meta-analysis on this issue was carried out with the aim to illustrate how differential exposure and outcome misclassifications may lead to uncertain conclusions. METHODS: Medline, searched to October 2019 for full text papers in English. Summary Odds Ratios (ORs) with confidence intervals (CIs) were calculated using random-effect models. Probabilistic sensitivity analyses were performed for evaluating the extension of differential misclassification required to account for the exposure-outcome association. RESULTS: Summary ORs were 1.02 (95 % CI, 0.92-1.15), 0.99 (0.82-1.19) and 1.25 (1.08-1.44) for overall congenital, cardiocirculatory, and central nervous system malformations respectively. By assuming exposure and outcome bias factor respectively of 0.95 (i.e., newborns with congenital defects had exposure specificity 5% lower than healthy newborns) and 1.12 (i.e., exposed newborns had outcome sensitivity 12 % higher than unexposed newborns), summary OR of central nervous system defects became 1.13 (95 % CI, 0.99-1.29) and 1.17 (95 % CI, 0.99-1.38). CONCLUSION: Observational investigations and meta-analyses of observational studies need cautious interpretations. Their susceptibility to several, often sneaky, sources of bias should be carefully evaluated.

Validation and factor structure of the Italian version of the Birth Satisfaction Scale-Revised (BSS-R).

OBJECTIVE: To validate the Italian-language version of the Birth Satisfaction Scale-Revised (BSS-R) and report key measurement properties of the tool. To evaluate the impact of antenatal class attendance on BSS-R assessed birth satisfaction. BACKGROUND: Maternal satisfaction is one of the standards of care defined by the World Health Organisation (WHO) to improve the quality of services. The BSS-R is a multi-dimensional self-report measure of the experience of labour and birth. METHODS: Cross-sectional instrument evaluation design examining factor structure and key aspects of validity and reliability. Embedded between-subjects design to examine known-group discriminant validity and the impact of antenatal class attendance on BSS-R sub-scale and total scores as dependent variables. After giving birth, 297 women provided data for analysis. RESULTS: The Italian version of the BSS-R (I-BSS-R) was the key study measure. The established three-factor and bi-factor models of the BSS-R were found to offer an excellent fit to the data. Comparison of the tri-dimensional measurement model and the bi-factor model of the BSS-R found no significant differences between models. Women who attended antenatal classes had significantly lower stress experienced during childbearing sub-scale scores (I-BSS-R SE), compared to those who did not. Good convergent, divergent validity and known-groups discriminant validity were established for the I-BSS-R. Internal consistency observations were found to be sub-optimal in this population. CONCLUSIONS: On all key psychometric indices, with the exception of internal consistency that requires further investigation, the I-BSS-R was found to be a valid translation of the original BSS-R. The impact of antenatal classes on birth satisfaction warrants further research.

Association of adverse perinatal outcomes of intrahepatic cholestasis of pregnancy with biochemical markers: results of aggregate and individual patient data meta-analyses.

BACKGROUND: Intrahepatic cholestasis of pregnancy is associated with adverse perinatal outcomes, but the association with the concentration of specific biochemical markers is unclear. We aimed to quantify the adverse perinatal effects of intrahepatic cholestasis of pregnancy in women with increased serum bile acid concentrations and determine whether elevated bile acid concentrations were associated with the risk of stillbirth and preterm birth. METHODS: We did a systematic review by searching PubMed, Web of Science, and Embase databases for studies published from database inception to June 1, 2018, reporting perinatal outcomes for women with intrahepatic cholestasis of pregnancy when serum bile acid concentrations were available. Inclusion criteria were studies defining intrahepatic cholestasis of pregnancy based upon pruritus and elevated serum bile acid concentrations, with or without raised liver aminotransferase concentrations. Eligible studies were case-control, cohort, and population-based studies, and randomised controlled trials, with at least 30 participants, and that reported bile acid concentrations and perinatal outcomes. Studies at potential higher risk of reporter bias were excluded, including case reports, studies not comprising cohorts, or successive cases seen in a unit; we also excluded studies with high risk of bias from groups selected (eg, a subgroup of babies with poor outcomes were explicitly excluded), conference abstracts, and Letters to the Editor without clear peer review. We also included unpublished data from two UK hospitals. We did a random effects meta-analysis to determine risk of adverse perinatal outcomes. Aggregate data for maternal and perinatal outcomes were extracted from case-control studies, and individual patient data (IPD) were requested from study authors for all types of study (as no control group was required for the IPD analysis) to assess associations between biochemical markers and adverse outcomes using logistic and stepwise logistic regression. This study is registered with PROSPERO, number CRD42017069134. FINDINGS: We assessed 109 full-text articles, of which 23 studies were eligible for the aggregate data meta-analysis (5557 intrahepatic cholestasis of pregnancy cases and 165 136 controls), and 27 provided IPD (5269 intrahepatic cholestasis of pregnancy cases). Stillbirth occurred in 45 (0·83%) of 4936 intrahepatic cholestasis of pregnancy cases and 519 (0·32%) of 163 947 control pregnancies (odds ratio [OR] 1·46 [95% CI 0·73-2·89]; I2=59·8%). In singleton pregnancies, stillbirth was associated with maximum total bile acid concentration (area under the receiver operating characteristic curve [ROC AUC]) 0·83 [95% CI 0·74-0·92]), but not alanine aminotransferase (ROC AUC 0·46 [0·35-0·57]). For singleton pregnancies, the prevalence of stillbirth was three (0·13%; 95% CI 0·02-0·38) of 2310 intrahepatic cholestasis of pregnancy cases in women with serum total bile acids of less than 40 µmol/L versus four (0·28%; 0·08-0·72) of 1412 cases with total bile acids of 40-99 µmol/L (hazard ratio [HR] 2·35 [95% CI 0·52-10·50]; p=0·26), and versus 18 (3·44%; 2·05-5·37) of 524 cases for bile acids of 100 µmol/L or more (HR 30·50 [8·83-105·30]; p<0·0001). INTERPRETATION: The risk of stillbirth is increased in women with intrahepatic cholestasis of pregnancy and singleton pregnancies when serum bile acids concentrations are of 100 µmol/L or more. Because most women with intrahepatic cholestasis of pregnancy have bile acids below this concentration, they can probably be reassured that the risk of stillbirth is similar to that of pregnant women in the general population, provided repeat bile acid testing is done until delivery.

Is perinatal asphyxia predictable?

BACKGROUND: The objective of our study was to evaluate the association between perinatal asphyxia and hypoxic-ischemic encephalopathy (HIE) with the presence of ante and intrapartum risk factors and/or abnormal fetal heart rate (FHR) findings, in order to improve maternal and neonatal management. METHODS: We did a prospective observational cohort study from a network of four hospitals (one Hub center with neonatal intensive care unit and three level I Spoke centers) between 2014 and 2016. Neonates of gestational age ≥ 35 weeks, birthweight ≥1800 g, without lethal malformations were included if diagnosed with perinatal asphyxia, defined as pH ≤7.0 or Base Excess (BE) ≤ - 12 mMol/L in Umbical Artery (UA) or within 1 h, 10 min Apgar < 5, or need for resuscitation > 10 min. FHR monitoring was classified in three categories according to the American College of Obstetricians and Gynecologists (ACOG). Pregnancies were divided into four classes: 1) low risk; 2) antepartum risk; 3) intrapartum risk; 4) and both ante and intrapartum risk. In the first six hours of life asphyxiated neonates were evaluated using the Thomson score (TS): if TS ≥ 5 neonates were transferred to Hub for further assessment; if TS ≥ 7 hypothermia was indicated. RESULTS: Perinatal asphyxia occurred in 21.5‰ cases (321/14,896) and HIE in 1.1‰ (16/14,896). The total study population was composed of 281 asphyxiated neonates: 68/5152 (1.3%) born at Hub and 213/9744 (2.2%) at Spokes (p < 0.001, OR 0.59, 95% CI 0.45-0.79). 32/213 (15%) neonates were transferred from Spokes to Hub. Overall, 12/281 were treated with hypothermia. HIE occurred in 16/281 (5.7%) neonates: four grade I, eight grade II and four grade III. Incidence of HIE was not different between Hub and Spokes. Pregnancies resulting in asphyxiated neonates were classified as class 1) 1.1%, 2) 52.3%, 3) 3.2%, and 4) 43.4%. Sentinel events occurred in 23.5% of the cases and FHR was category II or III in 50.5% of the cases. 40.2% cases of asphyxia and 18.8% cases of HIE were not preceded by sentinel events or abnormal FHR. CONCLUSIONS: We identified at least one risk factor associated with all cases of HIE and with most cases of perinatal asphyxia. In absence of risk factors, the probability of developing perinatal asphyxia resulted extremely low. FHR monitoring alone is not a reliable tool for detecting the probability of eventual asphyxia.

Umbilical cord management strategies at cesarean section.

AIM: To evaluate the effect of different strategies to improve placental transfusion in cesarean section (CS). METHODS: Retrospective analysis of all singleton term pregnancies that underwent CS over 6 months. Delayed umbilical cord clamping (dUCC) was defined as one done at least 60 s after birth. Umbilical cord milking (UCM) was an option when waiting 60 s was deemed unsafe. The two strategies were compared against early (<60 s) umbilical cord clamping (eUCC) without milking. Neonatal hematocrit (Hct) at 48 h was the main outcome variable. RESULTS: Of the 223 CS in the cohort, 100 were performed in labor and 123 were elective. dUCC was performed in 137, eUCC without milking in 53 and UCM in 33 cases. Neonatal Hct was higher in CS carried out in labor versus in elective CS (59.76% ± 6.17 vs 56.91% ± 5.95, P = 0.001). At multivariate analysis, CS performed in labor (coefficient [coeff.] 3.44, confidence interval [CI] 1.75-5.13, P < 0.001), UCM (coeff. 3.88, CI 1.61-6.14, P = 0.001) and birth weight (coeff. -0.003, CI -0.005 to -0.001, P = 0.001) were the only variables independently associated with neonatal Hct. In elective CS, UCM led to higher neonatal Hct (61.5% ± 5.5) compared to eUCC without milking (55.1% ± 5.5) and dUCC (56.4% ± 5.7, P = 0.001), while in CS performed in labor there were no significant differences among the placental transfusion strategies. CONCLUSION: In term CS, neonatal Hct is significantly higher when the CS is performed in labor or with UCM. In elective CS, UCM could be a valid option to favor placental transfusion.

Cesarean delivery rates and obstetric culture - an Italian register-based study.

INTRODUCTION: Cesarean delivery rates are rising due to multiple factors, including less use of operative vaginal delivery and vaginal birth after cesarean delivery, which often reflect local obstetric practices. Objectives of the study were to analyze the relations between cesarean delivery, these practices, and perinatal outcomes. MATERIAL AND METHODS: We included all deliveries in the 72 hospitals of Lombardia, a region in northern Italy, during the year 2013. The delivery certificate was used as data source. Pearson's correlation coefficient and logistic regression were used for statistical analysis. RESULTS: We included 87 896 deliveries. The number of deliveries per hospital ranged from 140 to 6123. The rate of cesarean delivery was 28.3% (range 9.9-86.4%), operative vaginal delivery 4.7% (range 0.2-10.0%), and vaginal birth after cesarean 17.3% (range 0-79.2%). We found a significant inverse correlation between rates of overall cesarean delivery and operative vaginal delivery (r = -0.25, p = 0.04). The correlation between rate of overall cesarean delivery and vaginal birth after cesarean was also inverse and significant (r = -0.57, p < 0.001). There was no association between overall cesarean delivery rate and the rates of Apgar score at 5 min <7 in term and late preterm neonates (r = -0.92, p = 0.46) and of perinatal mortality (r = -0.19, p = 0.13), respectively. The associations were independent of hospital volume of activity. CONCLUSIONS: An obstetric practice that encourages vaginal instrumental delivery in delayed second stage of labor or vaginal birth after previous cesarean delivery, could reduce the rising cesarean delivery rate. This will require a change in obstetric culture, continuing education of healthcare providers, and leadership.

Neonatal complications in vacuum-assisted vaginal delivery: are they associated with number of pulls, cup detachments, and duration of vacuum application?

PURPOSE: To explore whether the characteristics of vacuum delivery are associated with the occurrence of head injury and neonatal complications. METHODS: Retrospectively cohort study of vacuum-assisted attempted vaginal deliveries of singletons. We studied the association of total duration of vacuum application and number of pulls and cup dislodgement with (1) primary outcome: the occurrence of major (subgaleal hemorrhage, skull fracture, and intracranial hemorrhage) or minor (cephalohematoma, scalp laceration more extensive than simple abrasions) neonatal head injuries and (2) secondary outcome: the occurrence of neonatal complications, including 5-min Apgar score <7, umbilical artery pH < 7.10, shoulder dystocia, or need for neonatal intensive care unit admission. Logistic regression analysis was used to control for confounders. RESULTS: Vacuum-assisted delivery was attempted in 555 women. It was successful in 515 cases, and it failed in 40 (7.2 %). Head injury occurred in 32 (6.2 %) of vaginally delivered neonates, and it was related to duration of vacuum application (P = 0.004) and birth weight (P = 0.048). However, the associations lost a statistical significance at the multivariate analysis. Neonatal complications occurred in 25 cases (5 %), and they were associated with meconium-stained amniotic fluid (P < 0.001) and duration of vacuum application (P = 0.03) at the multivariate analysis. However, most of the complications were actually associated with the need for vacuum delivery rather than the procedure itself. CONCLUSION: Neonatal head injury after vacuum application is not independently related to total duration of vacuum application, number of pulls, or cup dislodgements.

Trial of labor after myomectomy and uterine rupture: a systematic review.

INTRODUCTION: There is concern about the risk of uterine rupture in the subsequent pregnancy after myomectomy. This risk is reported in literature to be around 0.7-1%. The aim of this study was to evaluate the incidence of uterine rupture and associated risk factors in women who had a trial of labor after prior myomectomy. MATERIAL AND METHODS: A systematic review of the literature was performed including all cohort studies with at least five cases reporting outcomes of pregnancies after prior myomectomy. The terms "myomectomy", "pregnancy", "trial of labor" and "uterine rupture" were used in PubMed and EMBASE searches for identification purposes. Every reference was reviewed for possible inclusion and all eligible cases of uterine rupture were considered. RESULTS: Twenty-three studies with at least five cases of pregnancy after myomectomy were identified, with an overall incidence of uterine rupture of 0.6% (0.3-1.1%) (n = 11/1825). Of these 23 studies, 11 studies reported detailed data about trial of labor after myomectomy and related pregnancy outcomes, including 1034 pregnancies and 756 viable (≥24 weeks) deliveries. The overall incidence of uterine rupture after myomectomy in the included studies was 0.93% (0.45-1.92%) (n = 7/756); specifically, it was 0.47% (0.13-1.70%) (n = 2/426) in women undergoing trial of labor after myomectomy, and 1.52% (0.65-3.51%) (n = 5/330) in women before the onset of labor. Of the seven uterine ruptures, five (71%) occurred within 36 weeks (range 24-40 weeks). CONCLUSIONS: Trial of labor after myomectomy is associated with a 0.47% risk of uterine rupture. There were no identified risk factors among the variables studied. The present systematic review of the literature revealed that uterine rupture after prior myomectomy occurred mainly before 36 weeks and before labor.

Fetal hydronephrosis: natural history and risk factors for postnatal surgery.

BACKGROUND: The objective of this study was to assess the ability of prenatal ultrasound to predict an unfavorable outcome and the need for postnatal surgery in cases of fetal hydronephrosis (HY). METHODS: Antenatal HY was classified according to the renal pelvis anteroposterior (AP) diameter in the third trimester. Postnatal outcome was considered favorable in the presence of spontaneous resolution or postnatal diagnosis of HY <20 mm, and unfavorable in the presence of postnatal diagnosis of >20 mm HY or urinary tract pathologies. RESULTS: Prenatal diagnosis of HY was made in 120 fetuses (for a total of 161 abnormal renal units). The rates of postnatal urinary tract pathology were 14, 27 and 53% for antenatal HY of ≤7, 8-15 and >15 mm, respectively. An AP diameter ≥7 mm in the third trimester had a sensitivity of 100% and a specificity of 23% to predict unfavorable outcome. A formula inclusive of AP diameter and presence or absence of urinary tract anomalies can predict the need for postnatal surgery. CONCLUSIONS: The majority of infants with congenital HY have a favorable postnatal outcome. Risk of unfavorable outcome increases with the degree of dilatation of the renal pelvis and the presence of urinary tract anomalies. An AP diameter ≥7 mm in the third trimester warrants postnatal follow-up.

Non-invasively collected amniotic fluid as a source of possible biomarkers for premature rupture of membranes investigated by proteomic approach.

PURPOSE: Preterm delivery is one of the main causes of perinatal morbidity and mortality and it accounts for 75 % of perinatal mortality and more than half of the long-term morbidity. We applied a proteomic approach based on mass spectrometry (MS) for biomarkers discovery of preterm premature rupture of membranes (pPROM) by investigating amniotic fluid (AF) invasively and non-invasively collected. METHODS: Amniotic fluid was obtained from vagina of women with pPROM (group 1), PROM at term (group 2) and by genetic amniocentesis (group 3). Pre-fractionated AF proteome was analyzed through matrix assisted laser desorption ionization-time of flight (MALDI-TOF) MS. The characterization of proteins/peptides of interest was obtained by high performance liquid chromatography-electrospray tandem MS. RESULTS: Three peptides overexpressed in pPROM and able to discriminate the groups 1 and 2 were detected. One peptide was identified as the fragment Gly452LAVPDGPLGLPPKPro466 of the protein KIAA1522, expressed by fetal brain and liver. This peptide was overexpressed in a patient of the group 3, completely asymptomatic at the time of the amniocentesis, who later developed pPROM. CONCLUSION: Amniotic fluid invasively and non-invasively collected can be analyzed by MALDI-TOF MS to obtain proteomic profiles. Proteomic analysis identified a peptide with promising diagnostic capability for pPROM.

Diffuse peritonitis secondary to urachal cyst abscess in a postpartum patient.

INTRODUCTION AND IMPORTANCE: Urachal cyst infections during pregnancy are exceptionally rare, posing diagnostic challenges. This case report contributes to the limited literature, emphasizing the rarity, diagnostic difficulties, and the need for heightened healthcare provider awareness for timely intervention. PRESENTATION OF CASE: A 32-year-old pregnant woman with persistent pelvic pain, fever, and urinary symptoms sought care with inconclusive initial diagnoses despite multiple ER visits. Labor revealed a palpable mass, and postpartum, a CT scan identified a urachal cyst abscess. Urgent laparoscopy confirmed peritonitis, leading to cyst removal, antibiotics, and a subsequent laparotomy. Histology confirmed an abscessed urachal cyst. DISCUSSION: Urachal cyst infections in pregnancy, exceptionally rare and diagnostically challenging, highlight the importance of considering them in abdominal pain differentials. Diagnostic tools, such as ultrasound and CT scans, can be misleading, emphasizing the necessity for a multidisciplinary approach. CONCLUSION: This case report underscores the challenges in diagnosing and managing an infected urachal cyst during pregnancy, stressing the need for awareness and a comprehensive diagnostic approach for optimal outcomes. The rarity of such cases warrants increased attention within the medical community.

Side effects from epidural analgesia in laboring women and risk of cesarean delivery.

BACKGROUND: Epidural analgesia may cause maternal hypotension and changes in the fetal heart rate. The implications of such side effects on the course of labor and delivery are incompletely understood. OBJECTIVE: This study aimed to assess whether the occurrence of maternal or fetal side effects associated with labor epidural analgesia increased the risk for cesarean delivery. STUDY DESIGN: This was a cohort study of all women who underwent epidural analgesia during labor for the period October 1, 2020 to December 31, 2020. Excluded were cases of multiples, fetal death, noncephalic presentation, and gestational age at birth <37.0 weeks. Maternal vital signs and fetal heart rate tracings for the 1 hour before and 1 hour after epidural analgesia was administered were reviewed. The occurrence of maternal hypotension, defined as a continuous variable and dichotomized into a decrease in maternal systolic blood pressure to <90 mm Hg or a drop in systolic blood pressure by >20% below the last value before epidural analgesia was administered, was related to changes in the fetal heart rate category. The principal outcome was cesarean delivery rate; binary logistic regression analysis was used to control for confounders, and mediation model analysis was used to quantify the extent to which significant variables participated in the causation pathway to cesarean delivery (SPSS version 28 was used for the analyses). RESULTS: A total of 439 women met the study criteria. Significant adverse reactions owing to epidural occurred in 184 of 439 women (41.9%) and included severe maternal hypotension in 159 of 439 participants (36.2%) and worsening fetal heart rate category in 50 of 439 participants (11.4%). The logistic regression analysis revealed that cervical dilation at epidural (P=.03), the duration of labor after epidural (P<.001), and worsening fetal heart rate category within 60 minutes of epidural administration (P=.01) were independently associated with recourse to cesarean delivery. The mediation analysis showed that both cervical dilatation at epidural administration and worsening fetal heart rate category had significant direct and indirect effects in the pathway to cesarean delivery. CONCLUSION: Worsening fetal heart rate category related to labor epidural independently increased the risk for cesarean delivery.

Intrapartum Quality of Care among Healthy Women: A Population-Based Cohort Study in an Italian Region.

Although the quality of care during childbirth is a maternity service's goal, less is known about the impact of the birth setting dimension on provision of care, defined as evidence-based intrapartum midwifery practices. This study's aim was to investigate the impact of hospital birth volume (≥1000 vs. <1000 births/year) on intrapartum midwifery care and perinatal outcomes. We conducted a population-based cohort study on healthy pregnant women who gave birth between 2018 and 2022 in Lombardy, Italy. A total of 145,224 (41.14%) women were selected from nationally linked databases. To achieve the primary aim, log-binomial regression models were constructed. More than 70% of healthy pregnant women gave birth in hospitals (≥1000 births/year) where there was lower use of nonpharmacological coping strategies, higher likelihood of epidural analgesia, episiotomy, birth companion's presence at birth, skin-to-skin contact, and first breastfeeding within 1 h (p-value < 0.001). Midwives attended almost all the births regardless of birth volume (98.80%), while gynecologists and pediatricians were more frequently present in smaller hospitals. There were no significant differences in perinatal outcomes. Our findings highlighted the impact of the birth setting dimension on the provision of care to healthy pregnant women.

Prenatal use of indomethacin for preterm labor and renal function among very low birth weight infants.

BACKGROUND: Indomethacin is administered as a tocolytic agent for threatening preterm labor <28weeks of gestation. Only a few, not conclusive, studies have investigated its nephrotoxicity in very low birth weight (VLBW) infants. We investigated whether indomethacin increases the incidence of acute kidney injury (AKI) among VLBW infants. METHODS: This is a retrospective study including all VLBW infants born at our center between January 1, 2005, and December 31, 2013. Indomethacin was administered to women with preterm labor and intact membranes. Neonatal AKI was defined according to KDIGO classification. Univariate analyses were performed comparing VLBW infants exposed to and not exposed to indomethacin. In the multivariable model, the association of indomethacin and AKI was adjusted for patent ductus arteriosus, use of nephrotoxic medications, birth weight, and gestational age. RESULTS: Five hundred seventy-five VLBW infants were included, 49 (8.5%) of whom were exposed to indomethacin in utero. The univariate analysis showed that infants exposed to indomethacin had lower birth weight, lower gestational age, and higher incidence of AKI than infants not exposed. The multivariable model adjusted for confounding factors confirmed an increased risk of AKI in relation to gestational age at birth <27 weeks, but not to indomethacin. CONCLUSIONS: Our data suggest that extreme prematurity, but not the use of indomethacin, is associated with AKI.
