The Contribution of Hypertensive Disorders of Pregnancy to Neonatal Unit Admissions and Iatrogenic Preterm Delivery at < 34+0 Weeks' Gestation in the UK: A Population-Based Study Using the National Neonatal Research Database.

OBJECTIVES: The objectives of this study were to (i) quantify the contribution of maternal hypertensive disorders of pregnancy (HDP) to iatrogenic preterm birth (PTB) and neonatal unit (NNU) admissions < 34+0 weeks and (ii) describe short-term population-level outcomes for HDP infants, exploring ethnic disparities and comparing outcomes by HDP exposure. DESIGN: Retrospective population-based study using the National Neonatal Research Database. SETTING: England and Wales. POPULATION: Infants born < 34+0 weeks and admitted to NNU 2012-2020. METHODS: Descriptive statistics, linear and logistic regression models to compare outcomes between groups. MAIN OUTCOME MEASURES: Survival to discharge with/without comorbidity. RESULTS: 122 228 infants met inclusion criteria. Where collected, 49 839/114 164 (43.7%, 95% CI 43.4%-43.9%) of infants had an iatrogenic PTB. HDP was recorded in 16 510/122 228 (13.5%) of all infants and 13 560/49 839 (27.2%) of iatrogenic PTBs. HDP and/or foetal growth restriction (FGR) were recorded in 24 124/49 839 (48.4%) of iatrogenic PTBs. Singleton HDP infants < 10th BWC had ≥ 90% survival to discharge from 28 weeks' gestation, versus from 26 weeks' gestation for those born ≥ 10th BWC. In extreme preterm HDP infants (< 27 weeks), 27.3% of infants < 10th BWC died compared to 15.2% of those ≥ 10th BWC. Survival without comorbidity was ≥ 90% from 32 weeks' gestation in HDP infants across BWC. CONCLUSIONS: These contemporaneous population-level data show that almost one in two PTB < 34+0 weeks' gestation are iatrogenic, with HDP and/or FGR being the major contributors to iatrogenic prematurity. This has substantial implications for strategies to reduce preterm birth in the UK and internationally. The data further inform antenatal and at-birth counselling of HDP-exposed infants.

Evaluation of angiogenic factors in prediction of growth-related neonatal morbidity at term and comparison with competing-risks model.

OBJECTIVES: First, to describe the distribution of biomarkers of impaired placentation in small-for-gestational-age (SGA) pregnancies with neonatal morbidity; second, to examine the predictive performance for growth-related neonatal morbidity of a high soluble fms-like tyrosine kinase-1 (sFlt-1)/placental growth factor (PlGF) ratio or low PlGF; and, third, to compare the performance of a high sFlt-1/PlGF ratio or low PlGF with that of the competing-risks model for SGA in predicting growth-related neonatal morbidity. METHODS: This was a prospective observational study of women attending for a routine hospital visit at 35 + 0 to 36 + 6 weeks' gestation in two maternity hospitals in England. The visit included recording of maternal demographic characteristics and medical history, an ultrasound scan and measurement of serum PlGF and sFlt-1. The primary outcome was delivery within 4 weeks after assessment and at < 42 weeks' gestation of a SGA neonate with birth weight < 10th or < 3rd percentile, combined with neonatal unit (NNU) admission for ≥ 48 h or a composite of major neonatal morbidity. The detection rates in screening by PlGF < 10th percentile, sFlt-1/PlGF ratio > 90th percentile, sFlt-1/PlGF ratio > 38 and the competing-risks model for SGA, using combinations of maternal risk factors and Z-scores of estimated fetal weight (EFW) with multiples of the median values of uterine artery pulsatility index, PlGF and sFlt-1, were estimated. The detection rates by the different methods of screening were compared using McNemar's test. RESULTS: In the study population of 29 035 women, prediction of growth-related neonatal morbidity at term provided by the competing-risks model was superior to that of screening by low PlGF concentration or a high sFlt-1/PlGF concentration ratio. For example, at a screen-positive rate (SPR) of 13.1%, as defined by the sFlt-1/PlGF ratio > 38, the competing-risks model using maternal risk factors and EFW predicted 77.5% (95% CI, 71.7-83.3%) of SGA < 10th percentile and 89.3% (95% CI, 83.7-94.8%) of SGA < 3rd percentile with NNU admission for ≥ 48 h delivered within 4 weeks after assessment. The respective values for SGA with major neonatal morbidity were 71.4% (95% CI, 56.5-86.4%) and 90.0% (95% CI, 76.9-100%). These were significantly higher than the respective values of 41.0% (95% CI, 34.2-47.8%) (P < 0.0001), 48.8% (95% CI, 39.9-57.7%) (P < 0.0001), 37.1% (95% CI, 21.1-53.2%) (P = 0.003) and 55.0% (95% CI, 33.2-76.8%) (P = 0.035) achieved by the application of the sFlt-1/PlGF ratio > 38. At a SPR of 10.0%, as defined by PlGF < 10th percentile, the competing-risks model using maternal factors and EFW predicted 71.5% (95% CI, 65.2-77.8%) of SGA < 10th percentile and 84.3% (95% CI, 77.8-90.8%) of SGA < 3rd percentile with NNU admission for ≥ 48 h delivered within 4 weeks after assessment. The respective values for SGA with major neonatal morbidity were 68.6% (95% CI, 53.1-83.9%) and 85.0% (95% CI, 69.4-100%). These were significantly higher than the respective values of 36.5% (95% CI, 29.8-43.2%) (P < 0.0001), 46.3% (95% CI, 37.4-55.2%) (P < 0.0001), 37.1% (95% CI, 21.1-53.2%) (P = 0.003) and 55.0% (95% CI, 33.2-76.8%) (P = 0.021) achieved by the application of PlGF < 10th percentile. CONCLUSION: At 36 weeks' gestation, the prediction of growth-related neonatal morbidity by the competing-risks model for SGA, using maternal risk factors and EFW, is superior to that of a high sFlt-1/PlGF ratio or low PlGF. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Parents' and neonatal healthcare professionals' views on barriers and facilitators to parental presence in the neonatal unit: a qualitative study.

BACKGROUND: Parent and infant separation in the neonatal unit is associated with adverse health outcomes. Family-integrated care has several advantages and the potential to reduce these adverse outcomes but requires parental presence. This study aimed to explore the views of parents and neonatal healthcare professionals (nHCPs) on barriers and facilitators to parental presence in a Swiss neonatal unit and to identify possible differences between nHCPs and parents, and between mothers and fathers. METHODS: Data were collected through semi-structured interviews with parents and focus group discussions with nHCPs. Inductive content analysis was used to identify barriers and facilitators to parental presence in the neonatal unit. RESULTS: Twenty parents (10 mothers and 10 fathers) and 21 nHCPs (10 nurses and 11 physicians) participated in the study. Parents and nHCPs experienced barriers and facilitators related to: (1) Structural factors of the institution, such as infrastructure or travel and distance to the neonatal unit. (2) Organization and time management of parental presence, daily activities, and work. (3) Resources, which include factors related to the legal situation, support services, family, and friends. (4) Physical and psychological aspects, such as pain, which mainly affected mothers, and aspects of emotional distress, which affected both parents. Self-care was an important physical and psychological facilitator. (5) Parent-professional interaction. Parental presence was influenced by communication, relationship, and interaction in infant care; and (6) Cultural aspects and language. Some perspectives differed between mothers and fathers, while the overall views of parents and nHCPs provided complementary rather than conflicting insights. Using visit plans to support the organization, educating nHCPs in knowledge skills and available resources to improve encouragement and information to parents, strengthening parent self-care, and improving nHCPs' attitudes towards parental presence were seen as possible improvements. CONCLUSIONS: Multifactorial barriers and facilitators determine parental presence and experience in the neonatal unit. Parents and nHCPs made specific recommendations to improve parental presence.

Effects of liberalising visiting policy and staff education on parental visiting duration in the neonatal unit.

AIM: The effect of different neonatal unit access hour policies on parental visiting duration is unknown. Therefore, we analysed the effects of access hours policies and parental education on parental visiting duration. METHOD: This prospective longitudinal cohort study was carried out in a level III neonatal unit from October 2020 to May 2022. Three cohorts were compared. The baseline cohort included 51 preterm infants with restricted visiting hours (October 2020 to May 2021). Cohort 1 comprised 35 preterm infants after liberalisation of visiting hours (June 2021 to November 2021). Cohort 2 consisted of 26 preterm infants after an educational program was implemented (December 2021 to May 2022). The primary outcome was the mean daily parental visiting duration. RESULTS: Mean maternal visiting duration was 172 (standard deviation, SD ± 49.2), 195 (SD ± 64.4.), and 258 (SD ± 71.1) minutes/day at baseline and in cohorts 1 and 2 (significant increase from baseline and cohort 1 to cohort 2, p < 0.001). Mean paternal visiting duration did not change significantly across the cohorts: 133 (SD ± 47.2), 135 (SD ± 83.5), and 165 (SD ± 71.3) minutes/day. CONCLUSION: Liberalisation of access hours did not increase parental visiting duration. Parental and staff education significantly increased maternal but not paternal visiting duration.

Immigrant and minority parents' experiences in a neonatal intensive care unit: A meta-ethnography review.

AIMS: To examine immigrant and minority parents' experiences of having a newborn infant in the neonatal intensive care unit and explore healthcare professionals' experiences in delivering care to immigrant and minority families. DESIGN: A meta-ethnographic review informed by eMERGe guidelines. METHODS: We conducted a systematic literature review. Studies were included if they explored immigrant or minority parent experiences in neonatal intensive care units and health professional experiences delivering care to immigrant and minority families in neonatal intensive care. Reporting followed ENTREQ guidelines. DATA SOURCES: Database searches included CINAHL, MEDLINE, PubMed, PsycINFO, Scopus and Google Scholar. Boolean search strategies were used to identify qualitative studies. No limitations on commencement date; the end date was 23rd August 2022. PRISMA guidelines used for screening and article quality assessed using Joanna Briggs Institute criteria for qualitative studies. RESULTS: Initial search yielded 2468 articles, and nine articles met criteria for inclusion. Three overarching themes were identified: (1) Overwhelming Emotions, (subthemes: Overwhelming Inadequacy; Cultural Expressions of Guilt; Not Belonging), (2) Circles of Support, (subthemes: Individual Level-Spirituality; External Level-Connecting with Family; Structured Peer-to-Peer Support), (3) Negotiating Relationships with Healthcare Professionals (subthemes: Connecting; Disconnected; Linguistic Barriers). Interactions between healthcare professionals and immigrant and minority parents were the strongest recurring theme. CONCLUSIONS: There can be a mismatch between immigrant and minority families' needs and the service support provided, indicating improvements in neonatal intensive care are needed. Despite challenges, parents bring cultural and family strengths that support them through this time, and many neonatal intensive care staff provide culturally respectful care. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Professionals should be encouraged to identify and work with family strengths to ensure parents feel supported in the neonatal intensive care unit. Findings can inform policy and practice development to strengthen health professionals capabilities to support immigrant and minority families in neonatal units. REPORTING METHOD: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklists were used to report the screening process.

The effect of the separation of mother-preterm newborn infants hospitalized during the COVID-19 pandemic on maternal depression and stress levels, infant development, and bonding quality on Chilean dyads.

Early infant development is a maturation process critically depends on the infant's interaction with primary caregivers. Hence, neonatal units prioritize their proximity. In COVID-19, parental visitation hours were limited, reducing caregivers time with their infants. This follow-up study analyzes and compares levels of maternal depression and stress, infant development, and bonding quality in preterm mother-infant dyads hospitalized, before and during the pandemic. Out of 66 dyads participated, 36 were admitted before COVID-19, and 30 during COVID-19. The assessed was two video-call sessions in which mothers completed selected questionnaires. No significant differences between mothers' levels of depression and stress. However, low birth weight was associated with greater difficulties in children's communication and interpersonal relationships. Furthermore, infants hospitalized in COVID-19 had a higher risk of experiencing delayed communication. No significant differences were observed in bonding quality. Lower infant gestational age and longer breastfeeding time were associated with better bonding quality in both groups. Psychosocial intervention is considered a valuable tool, capable of preventing maternal mental health difficulties and protecting bonding in premature infants and in highly complex healthcare settings. Nevertheless, it is essential to more actively address the socio-affective needs of newborns during their hospital stay to promote adequate development.

El desarrollo infantil temprano es un proceso de maduracion que depende críticamente de la interacción del infante consus cuidadores primarios. Por tal razón, en las unidades neonatales priorizan su proximidad. Durante el COVID­19, se limitaron las horas de visitas de los progenitores, lo que redujo el tiempo que los cuidadores con sus bebés. Este estudio de seguimiento analiza y compara el nivel de depresión y estrés materno, el desarrollo infantil y la calidad del vínculo afectivo en díadas madre­bebé prematuro hospitalizado al nacer, antes y durante la pandemia. De las 66 díadas participantes, 36 fueron admitidas antes del COVID­199 y a 30 durante el COVID­19. Se realizaron dos sesiones de vídeo­llamada, en las que las madres completaron los cuestionarios seleccionados. No se encontró ninguna diferencia significativa entre los niveles de depresión y estrés en las madres. Sin embargo, un bajo peso al nacer se asoció con mayores dificultades en la comunicación y las relaciones interpersonales en los niños. Además, los infantes hospitalizados durante el COVID­19 presentaron mayor riesgo de experimentar retrasos en la comunicación. No se observaron diferencias significativas en la calidad del vínculo afectivo. Una menor edad gestacional del infante y mayor tiempo de lactancia materna se asociaron con una mejor calidad del vínculo afectivo en ambos grupos. Se considera la intervención psicosocial como una herramienta de valor, capaz de prevenir dificultades en la salud mental materna y de proteger el vínculo afectivo en infantes nacidos prematuramente y en entornos sanitarios altamente complejos. Sin embargo, es esencial abordarmás activamente las necesidades socioafectivas de los recién nacidos durante su estadía en el hospital para promover un desarrollo adecuado.

High Prevalence of Candida auris Colonization during Protracted Neonatal Unit Outbreak, South Africa.

One third of patients were colonized by Candida auris during a point-prevalence survey in a neonatal unit during an outbreak in South Africa. The sensitivity of a direct PCR for rapid colonization detection was 44% compared with culture. The infection incidence rate decreased by 85% after the survey and implementation of isolation/cohorting.

Prediction of adverse perinatal outcome at midgestation.

OBJECTIVES: First, to investigate the association between adverse neonatal outcomes and birth weight and gestational age at delivery. Second, to describe the distribution of adverse neonatal outcomes within different risk strata derived by a population stratification scheme based on the midgestation risk assessment for small-for-gestational-age (SGA) neonates using a competing-risks model. METHODS: This was a prospective observational cohort study in women with a singleton pregnancy attending a routine hospital visit at 19 + 0 to 23 + 6 weeks' gestation. The incidence of neonatal unit (NNU) admission for ≥ 48 h was evaluated within different birth-weight-percentile subgroups. The pregnancy-specific risk of delivery with SGA < 10th percentile at < 37 weeks was estimated by the competing-risks model for SGA, combining maternal factors and the likelihood functions of Z-score of sonographically estimated fetal weight and uterine artery pulsatility index multiples of the median. The population was stratified into six risk categories: > 1 in 4, > 1 in 10 to ≤ 1 in 4, > 1 in 30 to ≤ 1 in 10, > 1 in 50 to ≤ 1 in 30, > 1 in 100 to ≤ 1 in 50 and ≤ 1 in 100. The outcome measures were admission to the NNU for a minimum of 48 h, perinatal death and major neonatal morbidity. The incidence of each adverse outcome was estimated in each risk stratum. RESULTS: In the study population of 40 241 women, 0.8%, 2.5%, 10.8%, 10.2%, 19.0% and 56.7% were in the risk strata > 1 in 4, > 1 in 10 to ≤ 1 in 4, > 1 in 30 to ≤ 1 in 10, > 1 in 50 to ≤ 1 in 30, > 1 in 100 to ≤ 1 in 50 and ≤ 1 in 100, respectively. Women in higher-risk strata were more likely to deliver a baby that suffered an adverse outcome. The incidence of NNU admission for ≥ 48 h was highest in the > 1 in 4 risk stratum (31.9% (95% CI, 26.9-36.9%)) and it gradually decreased until the ≤ 1 in 100 risk stratum (5.6% (95% CI, 5.3-5.9%)). The mean gestational age at delivery in SGA cases with NNU admission for ≥ 48 h was 32.9 (95% CI, 32.2-33.7) weeks for risk stratum > 1 in 4 and progressively increased to 37.5 (95% CI, 36.8-38.2) weeks for risk stratum ≤ 1 in 100. The incidence of NNU admission for ≥ 48 h was highest for neonates with birth weight below the 1st percentile (25.7% (95% CI, 23.0-28.5%)) and decreased progressively until the 25th to < 75th percentile interval (5.4% (95% CI, 5.1-5.7%)). Preterm SGA neonates < 10th percentile had significantly higher incidence of NNU admission for ≥ 48 h compared with preterm non-SGA neonates (48.7% (95% CI, 45.0-52.4%) vs 40.9% (95% CI, 38.5-43.3%); P < 0.001). Similarly, term SGA neonates < 10th percentile had significantly higher incidence of NNU admission for ≥ 48 h compared with term non-SGA neonates (5.8% (95% CI, 5.1-6.5%) vs 4.2% (95% CI, 4.0-4.4%); P < 0.001). CONCLUSIONS: Birth weight has a continuous association with the incidence of adverse neonatal outcomes, which is affected by gestational age. Pregnancies at high risk of SGA, estimated at midgestation, are also at increased risk for adverse neonatal outcomes. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Comparison of competing-risks model with angiogenic factors in midgestation screening for preterm growth-related neonatal morbidity.

OBJECTIVES: First, to evaluate the predictive performance for preterm growth-related neonatal morbidity of high soluble fms-like tyrosine kinase-1 (sFLT-1) / placental growth factor (PlGF) ratio or low PlGF at mid-gestation, and second, to compare the performance of the high sFLT-1/PlGF ratio or low PlGF with that of the competing risks model for small for gestational age (SGA), utilizing a combination of maternal risk factors, sonographic estimated fetal weight (EFW) and uterine artery pulsatility index (UtA-PI). METHODS: This was a prospective observational study in women attending for a routine hospital visit at 19 to 24 weeks' gestation in two maternity hospitals in England. The visit included recording of maternal demographic characteristics and medical history, carrying out an ultrasound scan and measuring serum PlGF and sFLT-1. The primary outcome was delivery <32 and <37 weeks' gestation of SGA neonate with birth weight <10th or <3rd percentile for gestational age, combined with neonatal unit (NNU) admission for ≥48 hours or a composite of major neonatal morbidity. The detection rates in screening by either PlGF <10th percentile, sFLT-1/PlGF ratio >90th percentile and the competing risks model for SGA were estimated and they were compared using McNemar's test. RESULTS: In the study population of 40241 women prediction of preterm growth-related neonatal morbidity provided by the competing risks model for SGA was superior to that of screening by low PlGF concentration or high sFlt-1/PlGF concentration ratio. For example, at screen positive rate (SPR) of 10.0%, as defined by the sFLT-1/ PlGF ratio >90th percentile, the competing risks model predicted 70.1% (95% CI 61.0 - 79.2) of SGA <10th percentile and 76.9% (67.6-86.3) of SGA <3rd percentile with NNU admission for ≥48 hours delivered <32 weeks gestation and these were significantly higher than the respective values of 35.0% (25.6-44.6) and 35.9% (25.3 - 46.5), achieved by the application of the sFLT-1/ PlGF ratio >90th percentile (p<0.0001 for both). The respective values for SGA with major neonatal morbidity were 73.8% (64.4-83.2), 77.9% (68.0-87.8), 38.1% (27.7-48.5) and 39.7% (28.1-51.3) (Both p<0.0001). CONCLUSION: At mid-gestation, the prediction of growth-related neonatal morbidity by the competing risks model for SGA is superior to that of high sFlt-1/PlGF ratio or low PlGF.

Prevalence and risk factors for postnatal mental health problems in mothers of infants admitted to neonatal care: analysis of two population-based surveys in England.

BACKGROUND: Previous research suggests that mothers whose infants are admitted to neonatal units (NNU) experience higher rates of mental health problems compared to the general perinatal population. This study examined the prevalence and factors associated with postnatal depression, anxiety, post-traumatic stress (PTS), and comorbidity of these mental health problems for mothers of infants admitted to NNU, six months after childbirth. METHODS: This was a secondary analysis of two cross-sectional, population-based National Maternity Surveys in England in 2018 and 2020. Postnatal depression, anxiety, and PTS were assessed using standardised measures. Associations between sociodemographic, pregnancy- and birth-related factors and postnatal depression, anxiety, PTS, and comorbidity of these mental health problems were explored using modified Poisson regression and multinomial logistic regression. RESULTS: Eight thousand five hundred thirty-nine women were included in the analysis, of whom 935 were mothers of infants admitted to NNU. Prevalence of postnatal mental health problems among mothers of infants admitted to NNU was 23.7% (95%CI: 20.6-27.2) for depression, 16.0% (95%CI: 13.4-19.0) for anxiety, 14.6% (95%CI: 12.2-17.5) for PTS, 8.2% (95%CI: 6.5-10.3) for two comorbid mental health problems, and 7.5% (95%CI: 5.7-10.0) for three comorbid mental health problems six months after giving birth. These rates were consistently higher compared to mothers whose infants were not admitted to NNU (19.3% (95%CI: 18.3-20.4) for depression, 14.0% (95%CI: 13.1-15.0) for anxiety, 10.3% (95%CI: 9.5-11.1) for PTS, 8.5% (95%CI: 7.8-9.3) for two comorbid mental health problems, and 4.2% (95%CI: 3.6-4.8) for three comorbid mental health problems six months after giving birth. Among mothers of infants admitted to NNU (N = 935), the strongest risk factors for mental health problems were having a long-term mental health problem and antenatal anxiety, while social support and satisfaction with birth were protective. CONCLUSIONS: Prevalence of postnatal mental health problems was higher in mothers of infants admitted to NNU, compared to mothers of infants not admitted to NNU six months after giving birth. Experiencing previous mental health problems increased the risk of postnatal depression, anxiety, and PTS whereas social support and satisfaction with birth were protective. The findings highlight the importance of routine and repeated mental health assessments and ongoing support for mothers of infants admitted to NNU.

Association between second- and third-trimester maternal lipid profiles and adverse perinatal outcomes among women with GDM and non-GDM: a retrospective cohort study.

BACKGROUND: Lipid metabolism disorder during pregnancy has been reported in women with gestational diabetes mellitus (GDM). However, controversy remains regarding the relationship between maternal changes in lipid profiles and perinatal outcomes. This study investigated the association between maternal lipid levels and adverse perinatal outcomes in women with GDM and non-GDM. METHODS: In total, 1632 pregnant women with GDM and 9067 women with non-GDM who delivered between 2011-2021 were enrolled in this study. Serum samples were assayed for fasting total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) levels during the second and third trimesters of pregnancy. Adjusted odds ratios (AOR) and 95% confidence intervals (95% CI) were calculated via multivariable logistic regression analysis to determine the association of lipid levels with perinatal outcomes. RESULTS: The serum TC, TG, LDL, and HDL levels in the third trimester were significantly higher than those in the second trimester (p < 0.001). Women with GDM had significantly higher levels of TC and TG in the second and third trimesters than those with non-GDM in the same trimesters, while HDL levels decreased in women with GDM (all p < 0.001). After adjusting for confounding factors by multivariate logistic regression, every mmol/L elevation in TG levels of women with GDM in second and third trimesters was associated with a higher risk of caesarean section (AOR = 1.241, 95% CI: 1.103-1.396, p < 0.001; AOR = 1.716, 95% CI: 1.556-1.921, p < 0.001), large for gestational age infants (LGA) (AOR = 1.419, 95% CI: 1.173-2.453, p = 0.001; AOR = 2.011, 95% CI: 1.673-2.735, p < 0.001), macrosomia (AOR = 1.220, 95% CI: 1.133-1.643, p = 0.005; AOR = 1.891, 95% CI: 1.322-2.519, p < 0.001), and neonatal unit admission (NUD; AOR = 1.781, 95% CI: 1.267-2.143, p < 0.001; AOR = 2.052, 95% CI: 1.811-2.432, p < 0.001) cesarean delivery (AOR = 1.423, 95% CI: 1.215-1.679, p < 0.001; AOR = 1.834, 95% CI: 1.453-2.019, p < 0.001), LGA (AOR = 1.593, 95% CI: 1.235-2.518, p = 0.004; AOR = 2.326, 95% CI: 1.728-2.914, p < 0.001), macrosomia (AOR = 1.346, 95% CI: 1.209-1.735, p = 0.006; AOR = 2.032, 95% CI: 1.503-2.627, p < 0.001), and neonatal unit admission (NUD) (AOR = 1.936, 95% CI: 1.453-2.546, p < 0.001; AOR = 1.993, 95% CI: 1.724-2.517, p < 0.001), which were higher than the relative risk of these perinatal outcomes in women with non-GDM. Additionally, every mmol/L increase in second and third-trimester HDL levels of women with GDM was associated with decreased risk of LGA(AOR = 0.421, 95% CI: 0.353-0.712, p = 0.007; AOR = 0.525, 95% CI: 0.319-0.832, p = 0.017) and NUD (AOR = 0.532, 95% CI: 0.327-0.773, p = 0.011; AOR = 0.319, 95% CI: 0.193-0.508, p < 0.001), and the risk reduction was not strong than that of women with GDM. CONCLUSIONS: Among women with GDM, high maternal TG in the second and third trimesters was independently associated with an increased risk of cesarean section, LGA, macrosomia, and NUD. High maternal HDL during the second and third trimesters was significantly associated with decreased risk of LGA and NUD. These associations were stronger than those in women with non-GDM, suggesting the importance of monitoring second and third-trimester lipid profiles in improving clinical outcomes, especially in GDM pregnancies.

Understanding the current and future usage of donor human milk in hospitals: An online survey of UK neonatal units.

The use of donor human milk (DHM) where there is a shortfall of maternal milk can benefit both infant and maternal outcomes but DHM supply is not always assured. This study aimed to understand current DHM usage in UK neonatal units and potential future demand to inform service planning. An online survey was disseminated to all UK neonatal units using Smart Survey or by telephone between February and April 2022 after development alongside neonatal unit teams. Surveys were completed by 55.4% of units (108/195) from all 13 Operational Delivery Networks. Only four units reported not using DHM, and another two units only if infants are transferred on DHM feeds. There was marked diversity in DHM implementation and usage and unit protocols varied greatly. Five of six units with their own milk bank had needed to source milk from an external milk bank in the last year. Ninety units (84.9%) considered DHM was sometimes (n = 35) or always (n = 55) supportive of maternal breastfeeding, and three units (2.9%) responded that DHM was rarely supportive of breastfeeding. Usage was predicted to increase by 37 units (34.9%), and this drive was principally a result of parental preference, clinical trials and improved evidence. These findings support the assumption that UK hospital DHM demand will increase after updated recommendations from the World Health Organization (WHO) and the British Association of Perinatal Medicine. These data will assist service delivery planning, underpinned by an ongoing programme of implementation science and training development, to ensure future equity of access to DHM nationally.

Competing-risks model for pre-eclampsia and adverse pregnancy outcomes.

OBJECTIVE: The competing-risks model for assessment of risk for pre-eclampsia (PE) at 35-37 weeks' gestation identifies the majority of women who are at high risk of subsequent delivery with PE. We aimed to examine the incidence and relative risk of adverse pregnancy outcomes in patient groups stratified according to the estimated risk of delivery with PE. METHODS: This was a prospective non-interventional, observational study in women with a singleton pregnancy attending for a routine hospital visit at 35 + 0 to 36 + 6 weeks' gestation. The risk of delivery with PE for each patient in the study population was estimated using the competing-risks model, combining the prior distribution of gestational age at delivery with PE and the likelihood from multiples of the median values of mean arterial pressure, placental growth factor and soluble fms-like tyrosine kinase-1. The patients were assigned to one of the following five risk categories: Group A, ≥ 1 in 2; Group B, 1 in 5 to 1 in 3; Group C, 1 in 20 to 1 in 6; Group D, 1 in 50 to 1 in 21; and Group E, < 1 in 50. The outcome measures were delivery with PE, gestational hypertension (GH), small-for-gestational age (SGA) at birth, delivery by Cesarean section, stillbirth, neonatal death, perinatal death and admission to the neonatal unit (NNU) for at least 48 h. In each risk category, the proportion of women with each adverse outcome was determined and relative risks (RR) were calculated as compared with the lowest-risk Group E. RESULTS: In the study population of 29 035 women, 1.6%, 2.7%, 8.2%, 9.8% and 77.8% were categorized into Groups A, B, C, D and E, respectively. Compared with women in Group E, women in the higher-risk groups were more likely to have an adverse outcome. The RR of delivery with PE in Group A compared with Group E was 65.5 (95% CI, 54.1-79.1) and the respective values were 11.9 (95% CI, 9.1-15.5) for GH, 1.8 (95% CI, 1.5-2.1) for delivery by emergency Cesarean section, 1.5 (95% CI, 1.2-1.8) for delivery by elective Cesarean section, 8.9 (95% CI, 7.4-10.8) for SGA with birth weight < 3rd percentile, 4.8 (95% CI, 4.3-5.4) for SGA with birth weight < 10th percentile, 5.3 (95% CI, 1.4-20.5) for stillbirth and 3.4 (95% CI, 2.8-4.2) for NNU admission for ≥ 48 h. The RR for these pregnancy complications in higher-risk groups (vs Group E) was particularly high for cases with delivery within 2 weeks after assessment. In terms of SGA, both for birth weight < 10th and < 3rd percentiles, the trend in all cases was stronger than that observed when the analysis was confined to normotensive pregnancies. The rates of neonatal death were too small to allow meaningful comparisons between risk groups. CONCLUSION: Pregnant women identified by the competing-risks model to be at high risk of PE are also at increased risk of GH, Cesarean section, stillbirth, SGA and NNU admission for ≥ 48 h. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

COVID-19 restrictions and psychological well-being of fathers with infants admitted to NICU-An exploratory cross-sectional study.

AIM: To describe the impact of the COVID-19 restrictions on the caregiving activities and psychological well-being of fathers with infants admitted to neonatal units. METHODS: Cross-sectional study using adapted COPE-IS and COPE-IU tools. Participants' recruitment occurred online via social media and parents' associations. Online survey in English, French and Italian were distributed and promoted via websites and social media platforms of parent's associations. The study was undertaken across 12 countries in Asia, Australia, Africa and Europe. RESULTS: A total of 108 fathers of NICU infants completed the survey. COVID-19 related restrictions were categorised into 3 types: no restrictions, partial and severe restrictions. Fathers who experienced partial restrictions reported more involvement in caregiving activities but high levels of emotional difficulties and sleeping problems compared to those who experienced full or no restrictions. CONCLUSION: Given the impact on the psychological well-being of fathers, restrictions should be avoided as much as possible in the neonatal unit and fathers given free access to their infants if they follow appropriate infection control precautions.

Support needs of parents in neonatal intensive care unit: An integrative review.

BACKGROUND: Having an infant in the neonatal intensive care unit (NICU) is associated with intense emotional stress for both mothers and fathers. However, with the right support from staff, this stress can be reduced significantly. Although evidence on needs of parents in the neonatal unit exists, there is lack of a systematic integrative review on the support needs of parents in the neonatal unit. Current review evidence is needed to support busy neonatal unit clinicians in their practice. AIM AND OBJECTIVES: The purpose of this integrative review is to explore the current available evidence to describe and understand the support needs of parents of infants in the NICU. METHODS: The integrative review process of Whittemore and Knafl (2005) was used to guide this study. Six databases-MEDLINE, CINHAL, PubMed, Scopus, Google Scholar and PsycINFO-were searched for eligible studies using relevant keywords. Primary studies published in English language from 2010 to 2021 were reviewed following a pre-determined inclusion criteria. Studies that met the inclusion criteria were critically appraised using the Mixed Methods Appraisal Tool (MMAT). The review report is guided by the PRISMA 2020 checklist for systematic reviews. RESULTS: Overall, 24 primary qualitative, quantitative and mixed methods studies were included in the review. Analysis of included studies resulted in six themes that demonstrate the support needs of parents in the NICU; 1. Information needs; 2. Emotionally intelligent staff; 3. Hands-on support; 4. Targeted support; 5. Emotional needs; and 6. Practical needs. CONCLUSION: This review has presented the current evidence on the needs of parents from their own perspective. Healthcare workers' understanding and supporting these needs in the NICU is likely to increase parental satisfaction and improve health outcomes for parents, infants and their family. RELEVANCE TO CLINICAL PRACTICE: Parents of infants in the NICU require staff support to enhance their experiences, well-being, caring and parenting confidence during admission and post-discharge. As parents are in constant need for informational, emotional and practical support, continuing professional development for NICU staff should place emphasis on effective communication strategies, enhancing emotional intelligence and empathy among staff. NICU staff should build positive ongoing relationships with parents and provide targetted support for mothers and fathers.

Chronic hypertension in pregnancy stratified by first-trimester blood pressure control and adverse perinatal outcomes: A prospective observational study.

INTRODUCTION: The aim of this study was to assess perinatal outcomes in women with chronic hypertension (CH) stratified into four groups according to their blood pressure (BP) control in the first trimester of pregnancy. MATERIAL AND METHODS: This was a prospective cohort study between January 2011 and June 2017, based in a university hospital in London, UK. The population consisted of four groups: group 1 included women without history of CH, presenting in the first trimester with BP >140/90 mmHg (n = 100). Groups 2-4 had prepregnancy CH; group 2 had BP <140/90 mmHg without antihypertensives (n = 234), group 3 had BP <140/90 mmHg with antihypertensives (n = 272), and group 4 had BP ≥140/90 mmHg despite antihypertensives (n = 194). The main outcome measures were: fetal growth restriction, admission to neonatal (NNU) or neonatal intensive care unit (NICU) for ≥2 days, composite neonatal morbidity, and composite serious adverse neonatal outcome. Outcomes were collected from the hospital databases and for up to 6 weeks postnatally. Differences between groups were assessed using chi-squared test and multivariate logistic regression was used to assess the independent contribution of the four groups to the prediction of pertinent outcomes, after controlling for maternal characteristics. RESULTS: There was a higher incidence of fetal growth restriction in groups 3 (17.6%) and 4 (18.2%), compared with groups 1 (10.0%) and 2 (11.1%) (P = .04). There were more admissions to the NNU for ≥2 days in groups 3 (23.2%) and 4 (25.0%), compared with groups 1 (17.0%) and 2 (13.2%) (P = .008); and more admissions to NICU for ≥2 days in groups 3 (9.2%) and 4 (9.4%), compared with groups 1 (3.0%) and 2 (3.4%) (P = .01). Composite neonatal morbidity was higher in groups 3 (22.4%) and 4 (21.4%), compared with groups 1 (17.0%) and 2 (11.5%) (P = .009). Composite serious adverse postnatal outcome was higher in groups 3 (3.3%) and 4 (4.2%), compared with groups 1 (1.0%) and 2 (0.9%) but the difference did not reach statistical significance (P = .09). These results were also observed when values were adjusted for maternal characteristics. CONCLUSIONS: In CH adverse perinatal outcomes are worse in women who are known to have CH and need antihypertensives in the first trimester of pregnancy. Women with newly diagnosed CH in the first trimester have similar outcomes to those with known CH who have antihypertensive treatment discontinued.

The effects of education levels of developmental care in Australia: Perceptions and challenges.

BACKGROUND: Developmental care consists of a range of clinical, infant-focused, and family-focused interventions designed to modify the neonatal intensive care environment and caregiving practices to reduce stressors on the developing brain. Since the inception of developmental care in the early 1980s, it has been recommended and adopted globally as a component of routine practice for neonatal care. Despite its application for almost 40 y, little is known of the attitude of neonatal nurses in Australia towards the intervention. AIMS AND OBJECTIVES: The objective of this study was to establish Australian neonatal nurse perceptions of developmental care and explore associations between developmental care education levels of the nurses and personal beliefs in the application of developmental care. DESIGN: This involves a cross-sectional survey design. METHODS: An online questionnaire was completed by 171 neonatal nurses. Participants were members of the Australian College of Neonatal Nursing (n = 783). Covariate associations between key components of developmental care and respondents' geographical location, place of employment, professional qualifications, and developmental care education level were analysed. The reporting of this study is in accordance with the Enhancing the Quality and Transparency of Health Research Checklist for Reporting Results of Internet E-Surveys. RESULTS: Differences were observed between groups for geographical location, place of employment, and professional qualification level. Rural nurses were less likely to support the provision of skin-to-skin care (odds ratio [OR]: 0.6, 95% confidence interval [CI]: 0.2-1.8) than nurses in a metropolitsan unit. Nurses working in a neonatal intensive care unit and nurses with postgraduate qualifications were more likely to support parental involvement in care ([OR: 2.3, 95% CI: 0.9-6.2] and [OR: 2.1, 95% CI: 0.6-7.4], respectively). Rural respondents were more likely to have attended off-site education (OR: 3.6, 95% CI: 1.3-9.9) than metropolitan respondents. CONCLUSION: The application of developmental care in Australia may be influenced by inadequate resources and inequitable access to educational resources, and similar challenges have been reported in other countries. Overcoming the challenges requires a focused education strategy and support within and beyond the neonatal intensive care unit.

Outbreak report of investigation and control of an outbreak of Panton-Valentine Leukocidin-positive methicillin-sensitive Staphylococcus aureus (PVL-MSSA) infection in neonates and mothers.

BACKGROUND: In January 2011, there was an outbreak of Panton-Valentine Leukocidin-positive methicillin-sensitive Staphylococcus aureus (PVL-MSSA) infection in a neonatal unit (NNU). We describe the investigation and control of an outbreak of PVL-MSSA infection in neonates. SETTING: Neonatal unit in West London. METHODS: We performed descriptive and analytical (case-control study) epidemiological investigations. Microbiological investigations including screening of MSSA isolates by PCR for the presence of the luk-PV, mecA and mecC genes and comparison of isolate with Pulsed field gel electrophoresis (PFGE). Control measures were also introduced. RESULTS: Sixteen babies were infected/colonised with the outbreak strain. Of these, one baby developed blood stream infection, 12 developed skin pustules and four babies were colonised. Four mothers developed breast abscesses. Eighty-seven babies in the unit were screened and 16 were found to have same PVL-MSSA strain (spa type t005, belonging to MLST clonal complex 22). Multivariate analysis showed gestational age was significantly lower in cases compared to controls (mean gestational age: 31.7 weeks v 35.6 weeks; P = 0.006). Length of stay was significantly greater for cases, with a median of 25 days, compared to only 6 days for controls (P = 0.01). Most (88%) cases were born through caesarean section, compared to less than half of controls. (P = 0.002). No healthcare worker carriers and environmental source was identified. The outbreak was controlled by stopping new admissions to unit and reinforcing infection control precautions. The outbreak lasted for seven weeks. No further cases were reported in the following year. CONCLUSIONS: Infection control teams have to be vigilant for rising prevalence of particular S. aureus clones in their local community as they may cause outbreaks in vulnerable populations in healthcare settings such as NNUs.

Biomarkers of impaired placentation at 35-37 weeks' gestation in the prediction of adverse perinatal outcome.

OBJECTIVE: To investigate the potential value of uterine artery pulsatility index (UtA-PI) and serum levels of the angiogenic placental growth factor (PlGF) and the antiangiogenic factor soluble fms-like tyrosine kinase-1 (sFlt-1) in the prediction of adverse perinatal outcome in small-for-gestational-age (SGA) and non-SGA neonates at 35-37 weeks' gestation. METHODS: This was a prospective observational study of 19 209 singleton pregnancies attending for a routine hospital visit at 35 + 0 to 36 + 6 weeks' gestation. This visit included recording of maternal demographic characteristics and medical history, sonographic estimation of fetal weight, color Doppler ultrasound for measurement of mean UtA-PI, and measurement of serum concentrations of PlGF and sFlt-1. Multivariable logistic regression analysis was carried out to determine which of the factors from maternal or pregnancy characteristics and measurements of UtA-PI, PlGF and sFlt-1 provided a significant contribution in the prediction of each of four adverse outcome measures: first, stillbirth; second, Cesarean delivery for suspected fetal compromise in labor; third, neonatal death or hypoxic ischemic encephalopathy Grade 2 or 3; and, fourth, admission to the neonatal unit (NNU) for ≥ 48 h. Predicted probabilities from logistic regression analysis were used to construct receiver-operating characteristics curves to assess the performance of screening for these adverse outcomes. RESULTS: First, 83% of stillbirths, 82% of Cesarean sections for presumed fetal compromise in labor, 91% of cases of neonatal death or hypoxic ischemic encephalopathy and 86% of NNU admissions for ≥ 48 h occurred in pregnancies with a non-SGA neonate. Second, UtA-PI > 95th percentile, sFlt-1 > 95th percentile and PlGF < 5th percentile were associated with increased risk of Cesarean delivery for suspected fetal compromise in labor and NNU admission for ≥ 48 h; the number of stillbirths and cases of neonatal death or hypoxic ischemic encephalopathy was too small to demonstrate significance in the observed differences from cases without these adverse outcomes. Third, multivariable logistic regression analysis demonstrated that, in the prediction of Cesarean delivery for suspected fetal compromise in labor, there was no significant contribution from biomarkers; the prediction of NNU admission for ≥ 48 h by maternal demographic characteristics and medical history was only marginally improved by the addition of sFlt-1 or PlGF. Fourth, for each biomarker, the detection rate of adverse outcome was higher in SGA than in non-SGA neonates, but this increase was accompanied by an increase in false-positive rate. Fifth, the relative risk of UtA-PI > 95th , sFlt-1 > 95th and PlGF < 5th percentiles for most adverse outcomes was < 2.5 in both SGA and non-SGA neonates. CONCLUSIONS: In pregnancies undergoing routine antenatal assessment at 35-37 weeks' gestation, measurements of UtA-PI, sFlt-1 or PlGF provide poor prediction of adverse perinatal outcome in both SGA and non-SGA fetuses.

Antimicrobial stewardship in the neonatal unit reduces antibiotic exposure.

AIM: Antimicrobial stewardship plays an important role in ensuring that the appropriate drug, dose, route and duration are employed to provide adequate treatment while minimising the risks of unnecessary antibiotic use. Surveillance of antibiotic use with prescriber feedback is recommended as a high-impact stewardship intervention. The aim of this study was to reduce unnecessary antimicrobial use in a neonatal unit. METHODS: A prospective audit was performed to assess compliance with antimicrobial guidelines. Following this, educational interventions were applied, electronic prescribing was introduced to the neonatal unit, and re-audit was performed. The primary outcome was a reduction in days of therapy (DOT). RESULTS: There were 312 neonatal admissions. There was a significant overall reduction in the primary outcome of DOT/1000 patient days from 572 to 417 DOT. This represents a 27% reduction in total antibiotic use. Prolonged antibiotic treatment courses >36 hours in negative sepsis evaluations were reduced from 82 DOT to 7.5 DOT. Similarly, treatment courses greater than five days for culture-negative sepsis were reduced from 46.5 DOT to 7 DOT. CONCLUSION: Monitoring antibiotic prescribing data can provide useful insights into the trends of antibiotic use and also inform clinicians of potential areas where antibiotic use may be safely reduced.
