Are expectations of labour and birth fulfilled? A qualitative investigation of first-time parents.

AIM: To describe if first-time parents' expectations of labour and birth, explored during the third trimester of pregnancy, were fulfilled or not when investigated 1 year following birth. DESIGN: Qualitative Husserlian phenomenological approach. METHODS: The sample comprises 10 parents (five couples), who participated in an online semi-structured audio-recorded individual interview conducted 1 year after birth, between September 2020 and October 2020. Parents' expectations of labour and birth, described throughout a focus group discussion on pregnancy, were compared with their experience explored 1 year after birth. A thematic analysis was adopted and member checking was used to validate participants' thoughts. RESULTS: Participants gave birth in a II level maternity unit and one-to-one midwifery care was provided. Although during the focus group conducted in pregnancy, women reported being aware of the unpredictable nature of childbirth, they expressed sadness and failure after experiencing some unexpected interventions. The midwife was a reassuring guide, as expected; however, sometimes, the communication was not effective, and women perceived lack of support. Some women partly blame themselves for not being prepared to manage labour pain, which hurt more than expected. Feeling of uncertainty about events were experienced in relation to seeking care at an early stage of labour, which confirmed the fears expressed during pregnancy. During the antenatal focus group discussion, fathers doubted they could be helpful for the labouring women. This negative emotion was confirmed after birth. However, they understood the importance to be present and to support their partner. CONCLUSIONS: One year after birth, participants had consistent memories of their birth experience. Professionals might identify fundamental components of quality maternity care that are meaningful for parents, with the potential to generate a long-term positive health impact on them. Respectful maternity care should be ensured through a family-centred approach, with the aim to promote satisfaction. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: The study highlights the importance of taking parents' expectations into account when providing antenatal care to tailor individualized support that addresses their distinct needs and preferences. Healthcare professionals might consider initiating a post-natal discussion with parents to assess whether their needs and perspectives have been addressed. This perspective may present valuable insights to achieve long-term positive outcomes, provide high-quality maternity care, address issues and make improvements. IMPACT: The study showed that 1 year after birth, parents can accurately recall their birth. They might also give significant insights into fundamental components of care that they value as crucial to shape a positive birthing experience. Professionals should use this information to build solutions, promoting long-term well-being for parents. Respectful interactions and trusting relationships emerged as key elements in parents' experience. A midwifery care focused on parents' needs may contribute to the achievement of positive birth memories. REPORTING METHOD: This study used the Standards for Reporting Qualitative Research checklist.

Midwives' stress and burnout during the Omicron wave in Italy: An observational survey.

AIM: To evaluate midwives' level of stress and burnout during the COVID-19 Omicron phase in Italy. Secondary aims were to explore the impact of the pandemic on midwives' personal dimensions and professional activities and potential supporting strategies. DESIGN: A mixed-methods study was undertaken from July to December 2022. METHODS: Data were collected using a national online observational survey. Descriptive and inferential analyses were performed to evaluate stress, burnout and the impact of the pandemic on personal and professional dimensions. A deductive qualitative approach was used to analyse open-ended responses, that were merged with quantitative data following a convergent mixed-methods approach. RESULTS: A total of 1944 midwives participated in the survey. The stress summary score mean was 10.34, and 562 midwives (28.91%) experienced burnout. The intention to reduce working hours was reported by 202 midwives (10.39%), with 60.40% (n = 122) of them experiencing burnout. The intention to leave clinical practice within the following 2 years was reported by 239 (12.29%), with 68.20% (n = 163) of them experiencing burnout. All the personal dimensions and professional activities considered were defined by more than half of midwives as being impacted 'Moderately' or 'To a great extent' by pandemic. Stress and burnout frequencies increased when the midwives' perception of the pandemic effects was higher. Potential supporting strategies described by midwives as the most important in increasing their ability to cope with the pandemic were 'Women's awareness of the midwives' role' (n = 1072; 55.14%) and 'Family and friends' emotional support' (n = 746; 38.38%). CONCLUSION: Our findings suggested strategies to support a positive and safe working environment for midwives during a pandemic emergency, with potential transferability to similar contexts when human resources are lacking. It is recommended that maternity services provide the necessary resources for a safe and supportive working environment to prevent high stress levels and chronic burnout. IMPACT: Studies conducted during the first COVID-19 pandemic wave showed an increased level of stress, anxiety, burnout, post-traumatic stress disorder and depression experienced by healthcare professionals; moreover, midwives experienced drastic changes in care pathways and policies with struggles identified when providing high-quality woman-centred care following pandemic restrictions. Although it is recommended, there is lack of knowledge about long-term psychological effects of COVID-19 for midwives. Our study highlights that during the Omicron wave midwives experienced a high level of stress and burnout with an impact on individual dimensions and professional activities. Their stress and burnout were influenced by several factors, including restrictions in place, lack of organizational acknowledgement, work overload and need for extra childcare cover. Maternity services should provide the necessary resources for a safe and supportive working environment to prevent high stress levels and chronic burnout. Recommendations on how to facilitate this are suggested. REPORTING METHOD: During the writing process, we referred to 'The Strengthening the Reporting of Observational Studies Epidemiology Statement', the guidelines for reporting observational studies from the Equator network. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution. WHAT DOES THIS PAPER CONTRIBUTE TO THE WIDER GLOBAL CLINICAL COMMUNITY?: Work overload conditions negatively impacted on the quality of maternity services. Improving organizational aspects, reducing working hours, promoting family and friends' emotional support and improving women's awareness of midwife's role were the main strategies reported by midwives. These suggestions for ensuring a positive and safe working environment for midwives during a pandemic emergency could potentially be applied to similar situations where human resources are lacking.

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.

Association of intrauterine growth restriction and low birth weight with acute kidney injury in preterm neonates.

BACKGROUND: Preterm birth alters nephrogenesis and reduces the total nephron number. Intrauterine growth restriction (IUGR) seems to worsen nephron loss, but only a few studies have investigated its role in neonatal kidney impairment. We investigated whether IUGR, defined as reduced estimated fetal growth and/or placental flow alterations and low birth weight z-score, increases the risk of developing acute kidney injury (AKI) in very preterm infants. METHODS: We performed a retrospective study including infants born with a birth weight (BW) ≤ 1500 g and/or gestational age (GA) ≤ 32 weeks admitted to our center between January 2016 and December 2021. Neonatal AKI was defined according to the neonatal KDIGO classification based on the decline of urine output and/or creatinine elevation. We used multivariable linear regressions to verify the association between AKI and GA, BW z-score, IUGR definition, and hemodynamically significant patent ductus arteriosus (PDA). RESULTS: We included 282 infants in the analysis, with a median (IQR) GA = 29.4 (27.4, 31.3) weeks, BW = 1150 (870, 1360) g, and BW z-score = - 0.57 (- 1.64, 0.25). AKI was diagnosed in 36 (13%) patients, and 58 (21%) had PDA. AKI was significantly associated with BW z-score (beta (std. error) = - 0.08 (0.03), p = 0.008) and severe IUGR (beta (std. error) = 0.21 (0.08), p = 0.009), after adjusting for GA and PDA. CONCLUSIONS: Our data suggest that low BW z-score and IUGR could represent adjunctive risk factors for kidney impairment in preterm babies.

Acute spontaneous non-hemorrhagic adrenal infarction in pregnancy: case-report and literature review.

Unilateral non-hemorrhagic adrenal infarction (NHAI) is a very uncommon cause of acute abdomen in pregnancy. Diagnosis is highly challenging due to its rarity, heterogeneity of clinical presentation, and inconclusiveness of the initial workup. Timely recognition is pivotal to ensuring optimal outcomes. Here we describe a case of spontaneous unilateral NHAI diagnosed in a singleton pregnant woman at 32 weeks' gestation at our centre and provide the findings of an extensive literature review on the topic. We identified 22 articles describing 31 NHAI cases in 30 obstetric patients: NHAI occurs more frequently on the right side and in the third trimester, and diagnosis is formulated more than 24 h after clinical presentation in 50% of cases; second-level imaging is always necessary to reach a definitive diagnosis and start appropriate treatment. A high degree of clinical suspicion is needed to promptly recognize NHAI in pregnancy, thus allowing appropriate multidisciplinary management and timely treatment initiation. Promotion of knowledge and awareness of NHAI as a potential cause of acute abdomen in pregnancy is mandatory to improve clinical practice and, ultimately, perinatal outcomes.

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.

Pregnancy and Delivery Outcomes in Women With Persistent Versus Resolved Low-Lying Placenta in the Late Third Trimester.

OBJECTIVES: The safest mode of delivery in low-lying placenta is debatable. Little is known about outcomes in low-lying placenta resolved during the late third trimester. We compare outcomes of women with persistent versus resolved low-lying placenta. METHODS: A retrospective analysis on a prospective cohort of women with low-lying placenta confirmed at 28-30 weeks sonography (01/2009 to 03/2018). Women were followed up serially every 2 to 3 weeks until delivery to assess the placental edge-to-internal os distance (IOD), and included if scan was performed within 28 days before delivery. RESULTS: There were 86 women: in 21 the low-lying placenta resolved, whereas in 65 persisted (n = 15 IOD 1-10 mm, n = 50 IOD 11-20 mm). Antepartum bleeding associated with higher rates of urgent cesarean delivery in 1-10 mm (P = .041) but not in 11-20 mm (P = 1.000) and >20 mm (P = .333). Among women with IOD >10 mm allowed to labor, vaginal delivery occurred in 76.7% (11-20 mm) and 94.1% (>20 mm) (P = .155), with no difference according to parity (70% and 80% in multiparas, P = .696; 60% and 72.7% in nulliparas, P = .698). Severe PPH (P = .922) and hemoglobin drop (P = .109) were similar among groups. Women with IOD 11-20 mm and >20 mm and vaginal delivery bled less than women with similarly located placenta and cesarean delivery (P = .009 and P = .048). CONCLUSIONS: Women with IOD >10 mm have high chances of deliver vaginally with no further increase of their hemorrhagic risk. Success of vaginal delivery is independent of parity and antepartum bleeding. Labor should be managed in an adequate hospital setting.

Zika Virus Targeting in the Developing Brain.

Zika virus (ZIKV), a positive-sense RNA flavivirus, has attracted considerable attention recently for its potential to cause serious neurological problems, including microcephaly, cortical thinning, and blindness during early development. Recent findings suggest that ZIKV infection of the brain can occur not only during very early stages of development, but also in later fetal/early neonatal stages of maturation. Surprisingly, after peripheral inoculation of immunocompetent mice on the day of birth, the first cells targeted throughout the brain were isolated astrocytes. At later stages, more neurons showed ZIKV immunoreactivity, in part potentially due to ZIKV release from infected astrocytes. In all developing mice studied, we detected infection of retinal neurons; in many mice, this was also associated with infection of the lateral geniculate, suprachiasmatic nuclei, and superior colliculus, suggesting a commonality for the virus to infect cells of the visual system. Interestingly, in mature mice lacking a Type 1 interferon response (IFNR-/-), after inoculation of the eye, the initial majority of infected cells in the visual system were glial cells along the optic tract. ZIKV microinjection into the somatosensory cortex on one side of the normal mouse brain resulted in mirror infection restricted to the contralateral somatosensory cortex without any infection of midline brain regions, indicating the virus can move by axonal transport to synaptically coupled brain loci. These data support the view that ZIKV shows considerable complexity in targeting the CNS and may target different cells at different stages of brain development.SIGNIFICANCE STATEMENT Zika virus (ZIKV) can cause substantial damage to the developing human brain. Here we examine a developmental mouse model of ZIKV infection in the newborn mouse in which the brain is developmentally similar to a second-trimester human fetus. After peripheral inoculation, the virus entered the CNS in all mice tested and initially targeted astrocytes throughout the brain. Infections of the retina were detected in all mice, and infection of CNS visual system nuclei in the brain was common. We find that ZIKV can be transported axonally, thereby enhancing virus spread within the brain. These data suggest that ZIKV infects multiple cell types within the brain and that astrocyte infection may play a more important role in initial infection than previously appreciated.

Valnoctamide Inhibits Cytomegalovirus Infection in Developing Brain and Attenuates Neurobehavioral Dysfunctions and Brain Abnormalities.

Cytomegalovirus (CMV) is the most common infectious cause of brain defects and neurological dysfunction in developing human babies. Due to the teratogenicity and toxicity of available CMV antiviral agents, treatment options during early development are markedly limited. Valnoctamide (VCD), a neuroactive mood stabilizer with no known teratogenic activity, was recently demonstrated to have anti-CMV potential. However, it is not known whether this can be translated into an efficacious therapeutic effect to improve CMV-induced adverse neurological outcomes. Using multiple models of CMV infection in the developing mouse brain, we show that subcutaneous low-dose VCD suppresses CMV by reducing the level of virus available for entry into the brain and by acting directly within the brain to block virus replication and dispersal. VCD during the first 3 weeks of life restored timely acquisition of neurological milestones in neonatal male and female mice and rescued long-term motor and behavioral outcomes in juvenile male mice. CMV-mediated brain defects, including decreased brain size, cerebellar hypoplasia, and neuronal loss, were substantially attenuated by VCD. No adverse side effects on neurodevelopment of uninfected control mice receiving VCD were detected. Treatment of CMV-infected human fetal astrocytes with VCD reduced both viral infectivity and replication by blocking viral particle attachment to the cell, a mechanism that differs from available anti-CMV drugs. These data suggest that VCD during critical periods of neurodevelopment can effectively suppress CMV replication in the brain and safely improve both immediate and long-term neurological outcomes.SIGNIFICANCE STATEMENT Cytomegalovirus (CMV) can irreversibly damage the developing brain. No anti-CMV drugs are available for use during fetal development, and treatment during the neonatal period has substantial limitations. We studied the anti-CMV actions of valnoctamide (VCD), a psychiatric sedative that appears to lack teratogenicity and toxicity, in the newborn mouse brain, a developmental period that parallels that of an early second-trimester human fetus. In infected mice, subcutaneous VCD reaches the brain and suppresses viral replication within the CNS, rescuing the animals from CMV-induced brain defects and neurological problems. Treatment of uninfected control animals exerts no detectable adverse effects. VCD also blocks CMV replication in human fetal brain cells.

Novel Therapy for the Treatment of Early-Onset Preeclampsia.

Preeclampsia is a multisystem disorder affecting 2% to 8% of pregnancies and a leading cause of maternal and perinatal morbidity and mortality worldwide. Recent investigations have improved our understanding of the pathogenesis of this potentially life-threatening disease, especially in its early-onset form of manifestation. Despite these advances, therapeutic options are still limited and no effective pharmacologic interventions are currently available. Ongoing lines of research indicate some potential novel treatments targeting specific pathogenic steps. In this article we provide an updated overview of the multiple therapeutic approaches under preclinical and clinical assessment for the treatment of early-onset preeclampsia.

PreImplantation Factor and Endocrinology of Implantation and Establishment of Early Pregnancy: A Contemporary View.

The earliest stages of pregnancy are marked by countless changes in the maternal environment. A specific coordination of activity is required for a successful pregnancy, starting early in the menstrual cycle. Early establishment of maternal-fetal crosstalk is critical for the progression of pregnancy. Many factors, both maternal and fetal derived, play specific and important roles immediately following fertilization, through implantation and beyond. Here we present a review of some of the key factors involved with a focus on PreImplantation Factor (PIF), a small peptide secreted only by competent embryos, which carries an important role required for pregnancy progression.

Recombinant Human Antithrombin in Pregnant Patients with Hereditary Antithrombin Deficiency: Integrated Analysis of Clinical Data.

OBJECTIVES: The purpose of this analysis was to evaluate the use of recombinant human antithrombin (rhAT) in preventing venous thromboembolism (VTE) in pregnant patients with hereditary AT deficiency (HATD). STUDY DESIGN: Data from two clinical trials were pooled. Dosing of rhAT was based on body weight and baseline AT activity, started up to 24 hours before scheduled induction or cesarean delivery, or at the onset of labor. RESULTS: A total of 21 pregnant HATD patients were enrolled. Mean rhAT therapy duration was 4.3 days and dose was 245.1 IU/kg/day. All patients achieved target mean AT activity (80-120% of normal) during rhAT therapy. There were no confirmed VTEs during rhAT treatment or within 7 ( ± 1) days after dosing. Two VTE events (one deep vein thrombosis and one pulmonary embolism) occurred 11 and 14 days after discontinuation of rhAT, in patients managed with prophylactic doses of heparin or low-molecular-weight heparin following delivery. CONCLUSION: rhAT was safe and effective in pregnant HATD patients when administered during the peripartum period, the period of highest VTE risk and a time when anticoagulation therapy is normally withheld. Pregnant HATD patients may benefit from therapeutic, rather than prophylactic, doses of anticoagulation after delivery to protect against postpartum VTE.

Thrombosis during pregnancy: Risks, prevention, and treatment for mother and fetus--harvesting the power of omic technology, biomarkers and in vitro or in vivo models to facilitate the treatment of thrombosis.

Maternal thromboembolism and a spectrum of placenta-mediated complications including the pre-eclampsia syndromes, fetal growth restriction, fetal loss, and abruption manifest a shared etiopathogenesis and predisposing risk factors. Furthermore, these maternal and fetal complications are often linked to subsequent maternal health consequences that comprise the metabolic syndrome, namely, thromboembolism, chronic hypertension, and type II diabetes. Traditionally, several lines of evidence have linked vasoconstriction, excessive thrombosis and inflammation, and impaired trophoblast invasion at the uteroplacental interface as hallmark features of the placental complications. "Omic" technologies and biomarker development have been largely based upon advances in vascular biology, improved understanding of the molecular basis and biochemical pathways responsible for the clinically relevant diseases, and increasingly robust large cohort and/or registry based studies. Advances in understanding of innate and adaptive immunity appear to play an important role in several pregnancy complications. Strategies aimed at improving prediction of these pregnancy complications are often incorporating hemodynamic blood flow data using non-invasive imaging technologies of the utero-placental and maternal circulations early in pregnancy. Some evidence suggests that a multiple marker approach will yield the best performing prediction tools, which may then in turn offer the possibility of early intervention to prevent or ameliorate these pregnancy complications. Prediction of maternal cardiovascular and non-cardiovascular consequences following pregnancy represents an important area of future research, which may have significant public health consequences not only for cardiovascular disease, but also for a variety of other disorders, such as autoimmune and neurodegenerative diseases.

Effect of access to antenatal care on risk of preterm birth among migrant women in Italy: A population-based cohort study.

Objective: To evaluate the association between maternal migration status and preterm birth, and whether a better adherence to antenatal care during pregnancy mitigates the risk of preterm birth. Design: Population-based cohort. Setting: Administrative databases of the Lombardy region, Italy. Population: First singleton births of women aged 15-55 years at 22-42 gestational weeks, between 2016 and 2021. Methods: Assessed the risk of preterm birth (<37 weeks). Main outcome measures: A multivariable logistic regression mediation model calculated the mediation effect of adherence to antenatal care in the association between maternal migrant status and preterm birth and the residual effect not mediated by it. Analyses were adjusted for the socio-demographic and pregnant characteristics of the women. Results: Of 349,753 births in the cohort, Italian nationality accounted for 71 %; 28.4 % were documented migrants and 0.4 % undocumented migrants. Among them, 5.3 %, 6.4 %, and 9.3 % had a preterm birth, respectively. Using deliveries of Italian citizens as referent, migrants had a significantly increased risk of preterm birth (adjusted relative risk: 1.22, 95 % confidence interval: 1.18-1.27). Adherence to antenatal care mediated the 62 % of such risk. We have calculated that adherence to antenatal pathways set to the highest level for the whole population could lead to a 37 % reduction in preterm birth risk. Conclusion: Part of the excess of preterm birth among documented and undocumented migrants in Italy can be explained by a lack of adherence to the antenatal care path despite equal access to National Health care. The adherence of all pregnant women to antenatal care would reduce the risk of preterm birth by about one-third.

Efficacy of antepartum fetal surveillance for stillbirth prevention.

OBJECTIVE: In 2019 the American College of Obstetricians and Gynecologists (ACOG) issued specific recommendations for performance of antepartum fetal surveillance (AFS) based on individual risk factors. As similar recommendations were already in place at our institution, we have evaluated the impact of AFS on stillbirth (SB) occurrence in a 5-year cohort. METHODS: Retrospective cohort study of all deliveries between 7/1/2013 and 6/30/2018. Excluded were multiples, anomalous fetuses or newborns, and deliveries before 32 0/7 weeks' gestation. AFS was conducted from 32 weeks with a modified biophysical profile, with a complete biophysical profile as back-up for non-reactive non-stress tests. All cases of SB were prospectively identified and individually reviewed to verify the presence of risk factors, the results of fetal testing if done, and calculate the interval between last fetal test and delivery. The electronic medical records during the study period were queried to identify women who underwent AFS and those who did not. Chi-square was used to compare the rates of SB between the two groups. RESULTS: 16,827 women fulfilled the study inclusion and exclusion criteria, 5711 (34%) had risk factors which prompted AFS; 37% had 2 or more risk factors. SB occurred in 1.8‰ of them (10/5711) (3 had 1 risk factor, 5 had 2, and 2 had 3 risk factors). Rates of SB at ≥32.0 weeks were similar between women who had AFS and those who did not (1.8 vs. 2.3‰, p = 0.51, OR = 0.75, 95%CI 0.36-1.55). The false-negative rate at <7 days of a reassuring AFS among compliant women was 1.4‰ (8/5711). Rates of preterm delivery were similar in the tested vs untested population (6.5 vs. 6.0%, p = 0.22). CONCLUSION: Implementation of AFS in women with risk factors similar to those recommended by the ACOG may lower the risk of SB from 32 weeks to that of low-risk pregnancies.

A vaginal birth is a cost-reduction strategy for women with a low-lying placenta.

BACKGROUND: Alongside health consequences, cesarean delivery (CD) has been associated with increased healthcare resource utilization (HCRU). A CD should be performed in case of placenta previa; in turn, the most appropriate mode of birth in women with a low-lying placenta (LLP) is still controversial. Since no previous data are available on the topic, the aim of this study was to evaluate the HCRU and economic impact on the Italian HC system of vaginal birth (VB) and CD in women with a LLP. METHODS: This retrospective study used patient-level real-world data of a cohort of women with a LLP confirmed at 28-30 weeks. A cost-minimization analysis (CMA) was conducted to compare VB and CD. Since Diagnosis-Related-Group payment may not reflect the actual use of hospital resources, a micro-costing analysis (MCA) was performed to more comprehensively evaluate the economic impact of VB and CD. RESULTS: The study included 86 women with a LLP at the third trimester scan, of which 49 (57%) had a VB and 37 (43%) underwent a CD. The CMA showed an economically marginal difference between VB and CD, especially when considering opportunity costs associated with the resources needed to look after women. However, the MCA identified charges for each VB being about half of those for each CD. CONCLUSIONS: The use of patient-level real-world data allowed to generate basic information to assess the value of available interventions in case of LLP. A VB should be promoted in women with LLP, avoiding further burden on the HC system's limited resources.

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.
