Early Hum Dev 2024; 197:106100. [PMID: 39180798 DOI: 10.1016/j.earlhumdev.2024.106100] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2024] [Revised: 08/14/2024] [Accepted: 08/14/2024] [Indexed: 08/27/2024]
Abstract
OBJECTIVE To investigate the association between prolonged oligohydramnios and a composite outcome of death or severe neurodevelopmental impairment (NDI) at 3 years of age. METHODS This single-center retrospective cohort study enrolled infants born at 22-29 weeks of gestational age without major congenital anomalies. The patients were classified into three groups depending on the existence and duration of oligohydramnios: no/non-prolonged oligohydramnios (no or 0-7 days of oligohydramnios), prolonged oligohydramnios (8-14 days), and very prolonged oligohydramnios (> 14 days). The primary outcome was a composite of death or severe NDI, which was defined as severe cerebral palsy, developmental delay, severe visual impairment, or deafness at age 3. RESULTS Out of the 843 patients, 784 (93 %), 30 (3.6 %), and 29 (3.4 %) were classified into the no/non-prolonged, prolonged, and very prolonged oligohydramnios groups, respectively. After excluding patients lost to follow-up, the adverse composite outcome at 3 years of age was observed in 194/662 (29 %), 7/26 (27 %), and 8/23 (35 %) in the corresponding groups. The composite outcome showed no significant trend with the duration of oligohydramnios (P = 0.70). In a logistic regression model controlling the known predictors of gestational age, birth weight, small-for-gestational-age, male sex, multiple pregnancy, hypertensive disorders of pregnancy, antenatal corticosteroids, and the number of family-social risk factors, the duration of oligohydramnios was not independently associated with the composite outcome; odds ratio 1.3 (95 % confidence interval, 0.78-2.0). CONCLUSION Prolonged oligohydramnios was not associated with the composite outcome of death or severe NDI at 3 years of age.

Abstract
BACKGROUND To investigate association of prenatal risk factors and neonatal outcomes of preterm infants with pulmonary hypertension (PH). METHODS A prospective cohort study of very-low-birth-weight infants born at 22-29 weeks' gestation who received PH-specific treatment during hospitalization. Infants were classified using a two-step cluster analysis based on gestational age (GA), small-for-gestational-age (SGA), exposure to antenatal corticosteroids (ACS), histologic chorioamnionitis (HCA), and oligohydramnios. RESULTS Among 910 infants, six clusters were identified: cluster A (HCA, n = 240), cluster B (oligohydramnios, n = 79), cluster C (SGA, n = 74), cluster D (no-ACS, n = 109), cluster E (no dominant parameter, n = 287), and cluster F (HCA and oligohydroamnios, n = 121). Cluster A was used as a reference group for comparisons among clusters. Compared to cluster A, cluster C (aHR: 1.63 [95% CI: 1.17-2.26]) had higher risk of overall in-hospital mortality. Clusters B (aHR: 1.52 [95% CI: 1.09-2.11]), D (aHR: 1.71 [95% CI: 1.28-2.30]), and F (aHR: 1.51 [95% CI: 1.12-2.03]) had higher risks of receiving PH-specific treatment within the first week of birth compared to cluster A. CONCLUSION These findings may provide a better understanding of prenatal risk factors contributing to the development of PH. IMPACT Pulmonary hypertension (PH), presenting as hypoxic respiratory failure, has complex etiologies in preterm infants. Although multifactorial risks for the development of PH in preterm infants are known, few studies have classified infants with similar etiologies for PH. Each cluster has distinct patterns of prenatal condition and neonatal outcome.

Abstract
Fetal lower urinary tract obstruction (LUTO) is associated with high mortality and postnatal morbidity caused by lung hypoplasia and impaired kidney function. Specific diagnostic features that can guide clinical approach and decisions are lacking; thus, the European Reference Network for Rare Kidney Diseases established a work group to develop recommendations regarding the clinical definition, diagnosis and management of prenatally detected LUTO. The work group recommends the use of antero-posterior diameter of renal pelvis as the most reliable parameter for suspecting obstructive uropathies and for suspecting prenatal LUTO in the presence of fetal megacystis. Regarding prenatal and postnatal prognosis of fetuses with LUTO, the risk of fetal and neonatal death depends on the presence of oligohydramnios or anhydramnios before 20 weeks' gestation, whereas the risk of kidney replacement therapy cannot be reliably foreseen before birth. Parents of fetuses with LUTO must be referred to a tertiary obstetric centre with multidisciplinary expertise in prenatal and postnatal management of obstructive uropathies, and vesico-amniotic shunt placement should be offered in selected instances, as it increases perinatal survival of fetuses with LUTO.

Abstract
PURPOSE Fetal megacystis (MC) can be severe and is mainly caused by fetal lower urinary tract obstruction (LUTO). Mortality of fetal LUTO can be high as a result of pulmonary hypoplasia and/or (chronic) renal insufficiency. Several technical procedures for vesicoamniotic shunting (VAS) were developed to improve fetal MC outcomes. MATERIAL AND METHODS We present the outcome of nine fetuses with MC who received VAS in the prenatal period (14 + 6 to 27 + 6 weeks GA) using the Somatex® intrauterine shunt system. MC was defined as an increased longitudinal measurement of the bladder >15 mm. The median follow-up time after birth was 18 months. RESULTS Eight Fetuses had uncomplicated VAS intervention. One case developed PPROM 24 h after VAS leading to abortion. Pregnancy was later terminated in further two cases. All six live-born infants received intensive care treatment. Invasive-mechanical ventilation was necessary in one case who died 24 h post-partum of severe cardiac depression. Five infants who survived the follow-up time developed chronic renal insufficiency (CRI), with one infant developing end-stage renal failure requiring peritoneal dialysis. CONCLUSION Overall, 5 of 9 LUTO fetuses (55%) undergoing VAS with the Somatex® intrauterine shunt system showed long-term survival beyond the neonatal period of 28 d (5/9; 55%) with varying morbidity.

Predicting previable preterm premature rupture of membranes (pPPROM) before 24 weeks: maternal and fetal/neonatal risk factors for survival. J OBSTET GYNAECOL 2021; 42:597-606. [PMID: 34382497 DOI: 10.1080/01443615.2021.1935818] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 10/20/2022]
Abstract
We sought to compare maternal and neonatal risk factors in cases with previable premature rupture of membranes (pPPROM, between 14-24 weeks) for optimal counselling. Therefore, 192 pregnancies of 485 cases which met selection criteria and agreed to follow-up were retrospectively analysed. Mean gestational age at pPPROM was 20.45 weeks. Live births occurred in 171 cases, but 67 (39.2%) of them died in the neonatal period (neonatal death group) and 104 cases (60.8%) constituted surviving neonate group. Of the surviving neonates, 37 (33.7%) experienced at least one complication. Most seen maternal complications were chorioamnionitis (24.48%) and placental abruption (8.33%). Although amniotic fluid volume, length of pPPROM period, completing antibiotherapy and CRP values were significant, amniotic fluid volume and length of pPPROM showed also significance for multivariate regression analysis for maternal risk factors. Risk factors for birth were gestational age at pPPROM, gestational age at birth, new-born weight at birth, 1st and 5th minute Apgar scores, umbilical cord pH value and need for neonatal resuscitation. Furthermore, development of respiratory distress syndrome, necrotising enterocolitis, intraventricular haemorrhage and retinopathy of premature were additional risk factors for neonate. Of them, gestational age at birth, new-born weight at birth, respiratory distress syndrome and retinopathy of prematurity were also significant in multivariate regression analysis.Impact StatementWhat is already known on this subject? Management of previable premature rupture of membranes is controversial and there is no definite consensus on the approach. The factor that best predicts neonatal survival is the gestational age at birth (Deutsch et al. 2010).What do the results of this study add? Appropriate counselling for pPPROM cases is important especially during antenatal period (maternal factors) and postpartum period (neonatal factors). Maternal infection risk is increased with an increased latency period of PPROM. As the gestational age at birth increases, the survival rate increases and neonatal complication rates decrease. Other important determinants of neonatal survival and well-being are the presence of oligo-anhydramnios and latency period of previable PPROM to delivery.What are the implications of these findings for clinical practice and/or further research? Counselling the patient with previable PPROM about pregnancy complications and paediatric outcome is challenging because of the small size, different gestational age ranges, and retrospective nature of the multiple studies on this subject. The most important feature of our study was the relatively high number of patients compared to other series. Thus, we can counsel pregnant women with PPROM prior to 24 weeks of gestation about the maternal antenatal factors and neonatal postnatal factors with related outcomes and help make an informed decision regarding termination or conservative follow-up. Nevertheless, there is a need for larger multicentric prospective studies to validate our data and to establish the prognosis of previable PPROM for both mother and foetus.

Abstract
Background Determination of the optimal timing for termination of pregnancy in cases of preterm premature rupture of membranes (pPROM) during the extremely preterm period is still difficult. Bronchopulmonary dysplasia (BPD) is a major disease widely taken into account when determining the prognosis of respiratory disorders in a neonate. Many aspects of this disease remain unclear. With the aim of further improving the prognosis of neonates born to mothers with pPROM, this study examined cases who were diagnosed with pPROM before 28 weeks of gestation. The study analysed risk factors for neonatal BPD. Methods This study included 73 subjects with singleton pregnancy, diagnosed with pPROM during the gestational period from 22 weeks and 0 days to 27 weeks and 6 days. The following factors were retrospectively examined: the gestational week at which pPROM was diagnosed, the gestational week at which delivery occurred, the period for which the volume of amniotic fluid was maintained, and neonatal BPD as a complication. Receiver operating characteristic (ROC) curve analyses were conducted to analyse the relationship of the onset of BPD with the duration of oligohydramnios and the gestational weeks of delivery. Results The mean gestational week at which a diagnosis of amniorrhexis was made was 24.5 ± 1.9 weeks (mean ± SD), and that at which delivery occurred was 27.0 ± 3.0 weeks. Fifty-seven cases (78.1%) were diagnosed with oligohydramnios, the mean duration of which was 17.4 ± 20.5 days. The mean birth weight of neonates was 1000 ± 455 g, of which 49 (67.1%) were diagnosed with BPD following birth. No neonates died in this study. The ROC curve indicated that the cut-off values for the duration of oligohydramnios and gestational age at delivery were 4 days and 24.1 weeks, respectively. Multivariate analysis indicated that the duration of oligohydramnios for more than 4 days before delivery and preterm delivery at less than 24.1 weeks were risk factors for the onset of BPD. Conclusions Our findings suggest that duration of oligohydramnios for more than 4 days before delivery and preterm delivery less than 24.1 weeks are risk factors for BPD in cases who are diagnosed with pPROM before 28 weeks of gestation.

Abstract
Background: Respiratory diseases in newborns are considered major causes of neonatal morbidity and mortality especially in developing countries. Its causes are diverse and require early detection and management. This study aimed for detection of the prevalence and risk factors of respiratory diseases in addition to outcome among neonates admitted in neonatal intensive care unit. Methods: Our study was a prospective observational study that was undertaken at the neonatal intensive care unit of Qena University Hospital, Egypt from July 2017 to July 2018. Demographic and clinical data of newborns and their mothers were evaluated and tabulated. Results: In this period, 312 neonates were admitted to the neonatal intensive care unit, out of them 145 suffered respiratory diseases giving a prevalence of (46.5%), and (55.9%) were males. The mean neonatal age at admission was 4.33 ± 7.19 days and mean gestational age was 34.49 ± 3.31 weeks. The most common detected respiratory diseases were respiratory distress syndrome (RDS; 49.6%), transient tachypnea of newborn (TTN; 22%), neonatal pneumonia (17.2%) and meconium aspiration syndrome (MAS; 6.21%). Premature rupture of membrane (PROM), maternal diabetes and fetal prematurity had the highest risk factors for respiratory diseases occurrence in neonates. Neonatal mortality rate was 26.2%, mainly due to hyaline membrane disease and pneumonia. Conclusion: Respiratory diseases constitute major part of total admission in neonatal intensive care unit especially RDS, TTN, pneumonia and MAS. Prematurity and maternal diabetes were the most important risk factors associated with respiratory diseases. Respiratory distress syndrome carried the highest risk of mortality and TTN carried the highest survival rate.

Abstract
Background Premature preterm rupture of membranes (PPROM) is reported to be associated with high rates of neonatal mortality and morbidity. Sildenafil has been used in infants with persistent pulmonary hypertension of newborn (PPHN) due to congenital diaphragmatic hernia (CDH) and bronchopulmonary dysplasia (BPD). Recently, Sildenafil has been evaluated as an alternative or adjunctive pulmonary vasodilator. This case report illustrates the use of early sildenafil for PPHN and right ventricular dysfunction in an unusual setting of lung and renal hypoplasia. Case presentation A male infant was born at 37 weeks with a birth weight of 2840 g. Rupture of membranes developed at approximately 24 weeks of gestational age (GA). Bilateral small kidneys (< 2 standard deviations below average) were detected on ultrasound (US) examination at 30 weeks of gestation. The baby developed pneumothorax and pulmonary hypertensive crisis towards the end of the first day. An echocardiogram showed a dilated right ventricle, moderate right ventricular systolic dysfunction, hypoplastic pulmonary arteries and a large patent ductus arteriosus with bidirectional flow. The patient was sedated, paralyzed, and inhaled nitric oxide was administered to decrease the pulmonary resistance. In anticipation of persistent pulmonary hypertension due to the hypoplastic lungs and small calibre of pulmonary arteries, sildenafil was started on day of life (DOL) 5 at a dosage of 0.25 mg/kg/dose Q8H and gradually increased to 2 mg/kg/dose Q8H on DOL 9. The patient was finally extubated on DOL 7 and weaned off of non-invasive respiratory support on DOL 26. Sildenafil was gradually weaned beginning on DOL 21 and discontinued on DOL 48. Repeat echocardiogram assessment at 3 months showed complete resolution of PHT and right ventricular dilatation. Conclusions We describe the early use of sildenafil in treating pulmonary hypertension associated with lung and renal hypoplasia in a non-CDH patient. Following this treatment the patient made a full recovery from right ventricular dysfunction.

Abstract
OBJECTIVE To assess the effectiveness of amnioinfusion in women with second-trimester preterm prelabor rupture of membranes. METHODS We performed a nationwide, multicenter, open-label, randomized controlled trial, the PPROM: Expectant Management versus Induction of Labor-III (PPROMEXIL-III) trial, in women with singleton pregnancies and preterm prelabor rupture of membranes at 16 0/7 to 24 0/7 weeks of gestation with oligohydramnios (single deepest pocket less than 20 mm). Participants were allocated to transabdominal amnioinfusion or no intervention in a one-to-one ratio by a web-based system. If the single deepest pocket was less than 20 mm on follow-up visits, amnioinfusion was repeated weekly until 28 0/7 weeks of gestation. The primary outcome was perinatal mortality. We needed 56 women to show a reduction in perinatal mortality from 70% to 35% (β error 0.20, two-sided α error 0.05). RESULTS Between June 15, 2012, and January 13, 2016, we randomized 28 women to amnioinfusion and 28 to no intervention. One woman was enrolled before the trial registration date (June 19, 2012). Perinatal mortality rates were 18 of 28 (64%) in the amnioinfusion group vs 21 of 28 (75%) in the no intervention group (relative risk 0.86, 95% CI 0.60-1.22, P=.39). CONCLUSION In women with second-trimester preterm prelabor rupture of membranes and oligohydramnios, we found no reduction in perinatal mortality after amnioinfusion.

Abstract
Objective: To elucidate the efficacy of continuous amnioinfusion on perinatal outcome in women with preterm premature rupture of membranes (PPROM) at periviable gestational ages.Methods: A database was reviewed to identify women with singleton pregnancies who were admitted to the Japanese Red Cross Nagoya Daiichi Hospital due to PPROM before 26 + 0-week gestation between July 2009 and July 2017.Results: A total of 81 women met the criteria for inclusion in this study including 70 and 11 women with and without amnioinfusion, respectively. The latency period between PPROM and delivery was significantly longer in women who underwent amnioinfusion compared with women without amnioinfusion (median: 13 versus 4 days, p < .001). In the survival analysis, the number of women who remained undelivered was significantly higher in the amnioinfusion group than in the non-amnioinfusion group for each gestational age after PPROM (p < .001). Cox's proportional hazards analysis with stepwise backward selection showed that both white blood cell counts on admission and amnioinfusion finally remained as variables that affected the time interval between PPROM and delivery [hazard ratio (95% confidence interval): 1.12 (1.06-1.18) and 0.34 (0.12-0.98), respectively].Conclusions: Continuous amnioinfusion in women with PPROM at periviable gestational ages resulted in significant prolongation of pregnancy and may help improve neonatal outcomes.

Outcomes of hypoxic respiratory failure at birth associated with previable rupture of membranes. J Perinatol 2018; 38:1087-1092.

Abstract
OBJECTIVE To characterize clinical outcomes of infants born after previable rupture of membranes (pROM, < 23 weeks gestation and latency period ≥ 2 weeks) in relation to refractory hypoxic respiratory failure (rHRF). STUDY DESIGN pROM neonates categorized as rHRF (FiO2 > 0.6 for ≥ 2 h) and treated (high frequency ventilation + inhaled nitric oxide) were compared with no rHRF group. Primary outcome was survival until discharge. Factors associated with rHRF and mortality were identified. RESULT Overall, mortality and disability rates were 28% and 22%, respectively. Treated rHRF group (n = 32) had longer period of ROM, mortality was (31% vs. 14%; p = 0.20), with similar survival-without-disability (54% vs. 47%; p = 0.67). Higher gestational age at birth [1.57 (1.03,2.39)] and cesarean delivery [12.6 (1.22,125)] were associated with increased survival. CONCLUSION Birth after pROM is associated with high rates of adverse outcomes, independent of latency period. Following treatment, rHRF infants may have similar long-term outcomes as those without rHRF.

Abstract
OBJECTIVE To describe survival rate after preterm premature rupture of membranes (PPROM) before 25 weeks of gestation and compare neonatal morbidity and mortality among those born alive with a control group of infants born at a similar gestational age without premature rupture of membranes. METHODS We conducted a retrospective single-centre study at Port-Royal maternity, from 2007 to 2015, comparing neonatal outcomes between liveborninfants exposed to PPROM prior to 25 weeks of gestation (WG) and a control group not exposed to premature rupture of the membranes. For each live-born child, the next child born after spontaneous labor without PPROM was matched for gestational age at birth, sex, and whether or not they received antenatal corticosteroid therapy. The primary endpoint was severe neonatal complications assessed by a composite endpoint including neonatal deaths, grade 3-4 HIV, bronchopulmonary dysplasia, leukomalacia and stade 3-4 retinopathies. RESULTS Among 77 cases of very premature rupture of the membranes, 55 children were born alive. Among these, the average gestational age at birth was 28 WG and 1 day. The rate of severe neonatal complications did not differ between the two groups (43.6% in the PPROM group vs. 36.4%, P=0.44) and the survival rate at discharge was also similar in the two groups (85.5% vs. 83.6%, P=0.98). CONCLUSIONS In our cohort and among livebirths after 24 WG, PPROM before 25 WG was not associated with an increased risk of morbidity and mortality compared to children born at the same gestational age after a spontaneous labor with intact membranes.

Abstract
OBJECTIVE To evaluate the effect on perinatal and postnatal survival of vesicoamniotic shunt (VAS) as treatment for fetal lower urinary tract obstruction (LUTO). METHODS An electronic search of Ovid MEDLINE, Ovid EMBASE, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews and Scopus using relevant search terms was conducted from inception to June 2015 to identify studies comparing outcomes of VAS vs conservative management for treatment of LUTO. Cohort studies and clinical trials were considered eligible. Single-arm studies and studies that did not report survival were excluded. Sample size and language were not criteria for exclusion. Two reviewers extracted independently data in a standardized form, including study characteristics and results. Primary outcomes were perinatal and postnatal survival. Secondary outcome was postnatal renal function. Data on fetal survival were expressed as odds ratio (OR) and 95% CI. RESULTS Of the 423 abstracts retrieved, nine studies were eligible for inclusion. These studies included 112 fetuses treated with VAS and 134 that were managed conservatively. There was heterogeneity in study design. Although the data demonstrated a difference in effect estimates between the study arms in terms of perinatal survival (OR, 2.54 (95% CI, 1.14-5.67)), there was no difference in 6-12-month survival (OR, 1.77 (95% CI, 0.25-12.71)) or 2-year survival (OR, 1.81 (95% CI, 0.09-38.03)). In addition, there was no difference in effect on postnatal renal function between fetuses that underwent intervention and those that did not (OR, 2.09 (95% CI, 0.74-5.94)). CONCLUSIONS Available data seem to support an advantage for perinatal survival in fetuses treated with VAS compared with conservative management. However, 1-2-year survival and outcome of renal function after VAS procedure remain uncertain. Further studies are necessary to evaluate the effectiveness of fetal intervention for LUTO based on different severity of the disease, due to the very low quality of the studies according to GRADE guidelines.

Abstract
OBJECTIVE To determine the hospital outcomes of liveborn infants at 23-31 weeks following prelabour preterm rupture of membranes (PPROM). METHOD A regional retrospective cohort study of 4454 infants of 23-31 weeks' gestation admitted to a tertiary neonatal network between 2007 and 2011. Primary outcome was the composite chronic lung disease (CLD) or mortality at discharge. RESULTS 225 (5%) neonates had a history of PPROM occurring prior to 24+0 weeks (Early-PPROM), 829 (19%) had a history of PPROM at or after 24+0 weeks' gestation (Late-PPROM) and 3400 (76%) had no history of PPROM (No-PPROM). In comparison to No-PPROM, Early-PPROM group had higher CLD/mortality in infants born at 23-27 weeks (OR 1.95; 95% CI 1.34 to 2.85) and 28-31 weeks (OR 4.98; 95% CI 2.99 to 8.28). Within Early-PPROM group, the latency of PPROM >14 days had lower CLD/mortality in comparison to latency ≤14 days (57.6% vs 77%, OR 0.40; 95% CI 0.21 to 0.76). Late-PPROM group had significantly lower CLD/mortality in comparison to No-PPROM group at 23-27 weeks (OR 0.50; 95% CI 0.37 to 0.69) and 28-31 weeks (OR 0.50; 95% CI 0.36 to 0.71). Within Late-PPROM group, latency >14 days was associated with an increased CLD/mortality in 28-31 weeks (14.1% vs 5.4%, OR 2.88; 95% CI 1.31 to 6.38). CONCLUSIONS Early-PPROM prior to 24 weeks' gestation had high incidence of CLD/mortality even after correcting for gestational age. Late-PPROM at or after 24 weeks had lower CLD/mortality compared with No-PPROM. Latency >14 days in Late-PPROM group at 28-31 week group increased the odds of CLD/mortality.

Abstract
OBJECTIVE It was the aim of our study to evaluate the independent effect of preterm prelabor rupture of membranes (PPROM) as a cause of preterm delivery on mortality during primary hospital stay and significant morbidities in very-low-birth-weight (VLBW) infants < 32 weeks of gestation. DESIGN Observational, epidemiological study design. SETTING Population-based cohort, German Neonatal Network (GNN). POPULATION 6102 VLBW infants were enrolled in GNN from 2009-2012, n=4120 fulfilled criteria for primary analysis (< 32 gestational weeks, no pre-eclampsia, HELLP (highly elevated liver enzymes and low platelets syndrome) or placental abruption as cause of preterm birth). METHODS Multivariable logistic regression analyses included PPROM as potential risk factors for adverse outcomes and well established items such as gestational age in weeks, birth weight, antenatal steroids, center, inborn delivery, multiple birth, gender and being small-for-gestational-age. RESULTS PPROM as cause of preterm delivery had no independent effect on the risk of early-onset sepsis, clinical sepsis and blood-culture proven sepsis, while gestational age proved to be the most important contributor to sepsis risk. The diagnosis of PPROM was associated with an increased risk for bronchopulmonary dysplasia (BPD; OR: 1.25, 95% CI: 1.02-1.55, p=0.03) but not with other major outcomes. CONCLUSIONS The diagnosis of PPROM per se is not associated with adverse outcome in VLBW infants < 32 weeks apart from a moderately increased risk for BPD. Randomized controlled trials with primary neonatal outcomes are needed to determine which subgroup of VLBW infants benefit from expectant or intentional management of PPROM.

Abstract
OBJECTIVE To evaluate neonatal survival after prolonged preterm premature rupture of membranes (PROM) in the era of antenatal corticosteroids, surfactant, and inhaled nitric oxide. METHODS A single-center retrospective cohort study of neonates born from 2002-2011 after prolonged (1 week or more) preterm (less than 24 weeks of gestation) rupture of membranes was performed. The primary outcome was survival to discharge. Neonates whose membranes ruptured less than 24 hours before delivery (n=116) were matched (2:1) on gestational age at birth, sex, and antenatal corticosteroid exposure with neonates whose membranes ruptured 1 week or more before delivery (n=58). Analysis used conditional logistic regression for categorical data and Wilcoxon signed rank test for continuous data. RESULTS The prolonged preterm PROM exposed and unexposed cohorts had survival rates of 90% and 95%, respectively, although underpowered to assess the statistical significance (P=.313). Exposed neonates were more likely have pulmonary hypoplasia (26/58 exposed, 1/114 unexposed, P<.001), pulmonary hypertension (21/56 exposed, 10/112 unexposed, P<.001), and pulmonary air leak (21/58 exposed, 14/114 unexposed, P<.001). Gestational age at rupture (20.4 weeks exposed, 22.3 weeks unexposed, P=.189), length of rupture (3.7 weeks exposed, 6.4 weeks unexposed, P=.717), and lowest maximal vertical pocket before 24 weeks of gestation (0 cm exposed, 1.4 cm unexposed, P=.114) did not discriminate between survivors and nonsurvivors after exposure to prolonged preterm PROM. CONCLUSION With antenatal steroid exposure and aggressive pulmonary management, survival to discharge after prolonged preterm PROM was 90%. Pulmonary morbidities were common. Of note, the data were limited to women who remained pregnant 1 week or longer after rupture of membranes.

Abstract
Respiratory distress presents as tachypnea, nasal flaring, retractions, and grunting and may progress to respiratory failure if not readily recognized and managed. Causes of respiratory distress vary and may not lie within the lung. A thorough history, physical examination, and radiographic and laboratory findings will aid in the differential diagnosis. Common causes include transient tachypnea of the newborn, neonatal pneumonia, respiratory distress syndrome (RDS), and meconium aspiration syndrome (MAS). Strong evidence reveals an inverse relationship between gestational age and respiratory morbidity. (1)(2)(9)(25)(26) Expert opinion recommends careful consideration about elective delivery without labor at less than 39 weeks’ gestation. Extensive evidence, including randomized control trials, cohort studies, and expert opinion, supports maternal group B streptococcus screening, intrapartum antibiotic prophylaxis, and appropriate followup of high-risk newborns according to guidelines established by the Centers for Disease Control and Prevention. (4)(29)(31)(32)(34) Following these best-practice strategies is effective in preventing neonatal pneumonia and its complications. (31)(32)(34). On the basis of strong evidence, including randomized control trials and Cochrane Reviews, administration of antenatal corticosteroids (5) and postnatal surfactant (6) decrease respiratory morbidity associated with RDS. Trends in perinatal management strategies to prevent MAS have changed. There is strong evidence that amnioinfusion, (49) oropharyngeal and nasopharyngeal suctioning at the perineum, (45) or intubation and endotracheal suctioning of vigorous infants (46)(47) do not decrease MAS or its complications. Some research and expert opinion supports endotracheal suctioning of nonvigorous meconium-stained infants (8) and induction of labor at 41 weeks’ gestation (7) to prevent MAS.

Abstract
BACKGROUND Preterm prelabour rupture of membranes (PPROM) before 26 weeks can delay lung development and can cause pulmonary hypoplasia, as a result of oligohydramnios. Restoring the amniotic fluid volume by transabdominal amnioinfusion might prevent abnormal lung development and might have a protective effect for neurological complications, fetal deformities and neonatal sepsis. OBJECTIVES To assess the effectiveness of transabdominal amnioinfusion in improving perinatal outcome in women with oligohydramnios secondary to rupture of fetal membranes before 26 weeks. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 April 2013). SELECTION CRITERIA All randomised controlled trials comparing transabdominal amnioinfusion with no transabdominal amnioinfusion. Cluster- or quasi-randomised trials were not eligible for inclusion. In cases where only an abstract was available, we attempted to find the full articles. DATA COLLECTION AND ANALYSIS Two review authors assessed trials for inclusion. No eligible trials were identified. MAIN RESULTS There are no included studies. AUTHORS' CONCLUSIONS There is currently no evidence to evaluate the use of transabdominal amnioinfusion in women with oligohydramnios secondary to rupture of fetal membranes before 26 weeks for improving perinatal outcome. Further research examining the effects of this intervention is needed. Two randomised controlled trials are ongoing but final data have not yet been published.

Abstract
In recent years, translational research with various animal models has been helpful to answer basic questions about the effect of antenatal inflammation on maturation and development of the fetal lung and immune system. The fetal lung and immune systems are very plastic and their development can be conditioned and influenced by both endogenous and/or exogenous factors. Antenatal inflammation can induce pulmonary inflammation, leading to lung injury and remodeling in the fetal lung. Exposure to antenatal inflammation can induce interleukin-1α production, which enhances surfactant protein and lipid synthesis thereby promoting lung maturation. Interleukin-1α is therefore a candidate for the link between lung inflammation and lung maturation, preventing respiratory distress syndrome in preterm infants. Antenatal inflammation can, however, cause structural changes in the fetal lung and affect the expression of growth factors, such as transforming growth factor-beta, connective tissue growth factor, fibroblast growth factor-10, or bone morphogenetic protein-4, which are essential for branching morphogenesis. These alterations cause alveolar and microvascular simplification resembling the histology of bronchopulmonary dysplasia. Antenatal inflammation may also affect neonatal outcome by modulating the responsiveness of the immune system. Lipopolysaccharide-tolerance (endotoxin hyporesponsiveness/immunoparalysis), induced by exposure to inflammation in utero, may prevent fetal lung damage, but increases susceptibility to postnatal infections. Moreover, prenatal exposure to inflammation appears to be a predisposition for the development of adverse neonatal outcomes, like bronchopulmonary dysplasia, if the preterm infant is exposed to a second postnatal hit, such as mechanical ventilation oxygen exposure, infections, or steroids.

Abstract
Whereas structural fetal abnormalities are relatively frequent occurrences, many of these do not impact measurably on future life and/or are amenable to postnatal therapy. A small minority are considered to be potentially lethal or life-limiting. Examples include specific skeletal dysplasias, urinary tract abnormalities - typically those which lead to anhydramnios and pulmonary hypoplasia, some disorders of the central nervous system and trisomies 13 and 18. Without seeking to compile an exhaustive list of such conditions, we discuss the principles and new considerations in relation to antenatal diagnosis and perinatal management of such disorders.

Abstract
BACKGROUND Improved neonatal survival data have been reported following early preterm prelabour rupture of membranes (PPROM) prior to 25 weeks gestation with a prolonged latency to delivery and persistent oligohydramnios. However, data regarding long-term respiratory and neurological morbidity are lacking. AIMS To evaluate the respiratory and neurological outcome data at two years of age in a cohort of infants born following PPROM prior to 25 weeks with a prolonged latency (14 days) to delivery and compare the data to an aged matched group of infants. METHODS Retrospective case note analysis over a 43-month period at Saint Luc University Hospital, Brussels. RESULTS 15 surviving infants born following PPROM were matched to a group of 30 control infants. Although there was no significant difference in the incidence of BPD between the groups (33% vs 27%, p=0.24), the length of hospitalisation, duration of respiratory support and number of hospital readmissions for respiratory indications were all significantly higher for infants born following a prolonged period of oligohydramnios. There were no major anomalies on cranial ultrasound in the PPROM group and Baileys developmental assessment at 20-24 months corrected gestational age showed no difference between the two groups (Mental development index 93.9 vs 94.4 and Psychomotor development index 95.5 vs 95.8 respectively p = ns). CONCLUSION Neurodevelopmental outcome appears encouraging in this cohort although these infants are at high risk of prolonged initial hospitalisation and significant respiratory morbidity in the first two-years of life.
