Reducing device-related pressure injuries in high-risk neonates receiving nasal continuous positive airway pressure: a quality improvement study.

Objective: Neonates requiring Non-InVasive respiratory Support (NIVS) are at high risk of device-related pressure injury (DRPI), with incidence rates of 20%-60% in extremely premature infants. Over a 4-year period, our team undertook a Quality Improvement Project to review aspects of the clinical management of NIVS: types of interfaces, introduction of hydrocolloid dressing and the development and implementation of nasal injury care plan (NICP) to reduce DRPI in high-risk neonates.

Design: A prospective descriptive study was completed in three stages: trial of nCPAP interfaces, preintroduction NICP (2016-2018), post-NICP (2018-2020) and (2021-2022) to measure sustainability of implementation.

Using Serum Cystatin C to Predict Acute Kidney Injury Following Infant Cardiac Surgery.

Acute kidney injury (AKI) following cardiopulmonary bypass (CPB) is associated with increased morbidity and mortality. Serum Cystatin C (CysC) is a novel biomarker synthesized by all nucleated cells that may act as an early indicator of AKI following infant CPB. Prospective observational study of infants (< 1 year) requiring CPB during cardiac surgery.

Neonatal hypoxic ischemic encephalopathy increases acute kidney injury urinary biomarkers in a rat model.

Hypoxic ischemic encephalopathy (HIE) is associated with acute kidney injury (AKI) in neonates with birth asphyxia. This study aimed to utilize urinary biomarkers to characterize AKI in an established neonatal rat model of HIE. Day 7 Sprague-Dawley rat pups underwent HIE using the Rice-Vannucci model (unilateral carotid ligation followed by 120 mins of 8% oxygen).

Humidification Practices of Extremely Preterm Neonates: A Clinical Survey.

Extremely preterm neonates are at risk of morbidity and mortality related to their underdeveloped skin barrier. Humidified incubators are typically used in their care, but there is a paucity of literature to inform the standardization of specific evidence-based humidification practices in the NICU. A brief, voluntary, anonymous survey was distributed to our home institution and numerous national and international external institutions.

Fluid Homeostasis and Diuretic Therapy in the Neonate.

Understanding physiologic water balance and homeostasis mechanisms in the neonate is critical for clinicians in the NICU as pathologic fluid accumulation increases the risk for morbidity and mortality. In addition, once this process occurs, treatment is limited. In this review, we will cover fluid homeostasis in the neonate, explain the implications of prematurity on this process, discuss the complexity of fluid accumulation and the development of fluid overload, identify mitigation strategies, and review treatment options.

Maternal Hypertension Disorders and Neonatal Acute Kidney Injury: Results from the AWAKEN Study.

Objective: This study aimed to examine the association between maternal hypertension (HTN) exposure and neonatal acute kidney injury (AKI).

Study Design: Retrospective cohort study of 2,162 neonates admitted to 24 neonatal intensive care units (NICUs). Neonates were classified into the following exposure groups: any maternal HTN, chronic maternal HTN, preeclampsia/eclampsia, both, or neither.

Impact of introducing a lactation consultant into a neonatal unit.

Aim: Benefits of mothers' own milk (MOM) for premature and sick neonates are well documented. To increase access, many neonatal units have a lactation consultant (LC) on staff. This study aimed to assess the impact of a permanent LC on (i) maternal access to LC support; (ii) staff confidence in providing Breast Feeding (BF) education and (iii) provision of MOM.

Advances in Neonatal Acute Kidney Injury.

In this state-of-the-art review, we highlight the major advances over the last 5 years in neonatal acute kidney injury (AKI). Large multicenter studies reveal that neonatal AKI is common and independently associated with increased morbidity and mortality. The natural course of neonatal AKI, along with the risk factors, mitigation strategies, and the role of AKI on short- and long-term outcomes, is becoming clearer.

Neonatal Acute Kidney Injury: Understanding of the Impact on the Smallest Patients.

The study of neonatal acute kidney injury (AKI) has transitioned from small, single-center studies to the development of a large, multicenter cohort. The scope of research has expanded from assessment of incidence and mortality to analysis of more specific risk factors, novel urinary biomarkers, interplay between AKI and other organ systems, impact of fluid overload, and quality improvement efforts. The intensification has occurred through collaboration between the neonatology and nephrology communities.

'Turning the tide' on hyperglycemia in pregnancy: insights from multiscale dynamic simulation modeling.

Introduction: Hyperglycemia in pregnancy (HIP, including gestational diabetes and pre-existing type 1 and type 2 diabetes) is increasing, with associated risks to the health of women and their babies. Strategies to manage and prevent this condition are contested. Dynamic simulation models (DSM) can test policy and program scenarios before implementation in the real world.

The Effect of Preterm Birth on Renal Development and Renal Health Outcome.

Preterm birth is associated with adverse renal health outcomes including hypertension, chronic kidney disease, and an increased rate of progression to end-stage renal failure. This review explores the antenatal, perinatal, and postnatal factors that affect the functional nephron mass of an individual and contribute to long-term kidney outcome. Health-care professionals have opportunities to increase their awareness of the risks to kidney health in this population.

Incidence and Risk Factors of Early Onset Neonatal AKI.

Background And Objectives: Neonatal AKI is associated with poor short- and long-term outcomes. The objective of this study was to describe the risk factors and outcomes of neonatal AKI in the first postnatal week.

Design, Setting, Participants, & Measurements: The international retrospective observational cohort study, Assessment of Worldwide AKI Epidemiology in Neonates (AWAKEN), included neonates admitted to a neonatal intensive care unit who received at least 48 hours of intravenous fluids.

Uncertainty over implications of placental histopathological findings: A survey of Australian and New Zealand neonatologists.

Aim: Placental examination is known to provide useful information following an adverse pregnancy outcome. Despite existing literature and guidelines for placental examination; current workplace practices, attitudes towards the value of placental examination and the knowledge of perinatal clinicians regarding placental lesions of significance are unknown. The aim of the study is to explore the current knowledge of neonatologists and maternal fetal medicine specialists on placental histopathological findings and clinical management based on placental pathology.

Renal dysfunction is already evident within the first month of life in Australian Indigenous infants born preterm.

Antecedents of the high rates of chronic kidney disease in Australian Indigenous peoples may originate early in life. Fourteen percent of Australian Indigenous infants are born preterm (under 37 weeks gestation) and, therefore, at risk. Here, our observational cohort study sought to determine the impact of preterm birth on renal function in Australian Indigenous and non-Indigenous infants.

A pilot randomised clinical trial of 670 nm red light for reducing retinopathy of prematurity.

Background: Photobiomodulation by 670 nm red light in animal models reduced severity of ROP and improved survival. This pilot randomised controlled trial aimed to provide data on 670 nm red light exposure for prevention of ROP and survival for a larger randomised trial.

Methods: Neonates <30 weeks gestation or <1150 g at birth were randomised to receive 670 nm for 15 min (9 J/cm) daily until 34 weeks corrected age.

Perceptions of Australian and New Zealand clinicians caring for neonates born at the borderline of viability have changed since the 2005 consensus guideline.

Aim: To determine whether clinician and consumer considerations have changed regarding the resuscitation and support of neonates born at the borderlines of viability since the 2005 New South Wales (NSW) and Australian Capital Territory (ACT) consensus guidelines were developed.

Methods: A prospective survey based on the hypotheses and scenarios developed in the original NSW and ACT consensus workshop on perinatal care at the borderlines of viability was sent to neonatologists, fetal medicine specialists, clinical midwife and clinical neonatal consultants and consumer representatives in Australia and New Zealand. Four scenarios and 16 questions were used to explore the respondent's views towards different aspects of the management of neonates born at the borderlines of viability.

Late onset neonatal acute kidney injury: results from the AWAKEN Study.

Background: Most studies of neonatal acute kidney injury (AKI) have focused on the first week following birth. Here, we determined the outcomes and risk factors for late AKI (>7d).

Neonatal hypertension: an educational review.

Hypertension is encountered in up to 3% of neonates and occurs more frequently in neonates requiring hospitalization in the neonatal intensive care unit (NICU) than in neonates in newborn nurseries or outpatient clinics. Former NICU neonates are at higher risk of hypertension secondary to invasive procedures and disease-related comorbidities. Accurate measurement of blood pressure (BP) remains challenging, but new standardized methods result in less measurement error.

Incidence of neonatal hypertension from a large multicenter study [Assessment of Worldwide Acute Kidney Injury Epidemiology in Neonates-AWAKEN].

Background: Hypertension occurs in up to 3% of neonates admitted to the Neonatal Intensive Care Unit (NICU), and is a potentially under-recognized condition. The aim of this study was to examine the incidence of documented and undiagnosed hypertension from the 24-center Assessment of Worldwide Acute Kidney Injury Epidemiology in Neonates (AWAKEN) database, and to assess risk factors for hypertension according to gestational age.

Methods: Diagnosed hypertension was documented if an infant had a discharge diagnosis of hypertension and/or discharged on antihypertensive medications.

Development of the Human Fetal Kidney from Mid to Late Gestation in Male and Female Infants.

Background: During normal human kidney development, nephrogenesis (the formation of nephrons) is complete by term birth, with the majority of nephrons formed late in gestation. The aim of this study was to morphologically examine nephrogenesis in fetal human kidneys from 20 to 41weeks of gestation.

Methods: Kidney samples were obtained at autopsy from 71 infants that died acutely in utero or within 24h after birth.
