Abstract
PURPOSE To analyze the association between risk factors and severe intraventricular hemorrhage (grade II-IV) in PNB under 1500 g. METHODS Multicenter, retrospective, analytical, case-control study in PNB under 34 weeks and under 1500 g admitted to the NICU. CASE PNB with severe intraventricular hemorrhage (grade II-IV). Logistic regression analysis was used to adjust for IVH-associated variables and odds ratios (OR). RESULTS A total of 90 PNB files were analyzed, 45 cases and 45 controls. The highest risk factors for severe IVH were lower gestational age (OR 1.3, p < 0.001), perinatal asphyxia (OR 12, p < 0.001), Apgar < 6 at minute 1 and 5 (OR 6.3, p < 0.001). CONCLUSION Lower gestational age, birth asphyxia, Apgar score lower of 6, and respiratory-type factors are associated with increased risk for severe IVH.

Neurodevelopmental outcome in preterm infants with intraventricular hemorrhages: the potential of quantitative brainstem MRI. Cereb Cortex 2024; 34:bhae189. [PMID: 38715405 PMCID: PMC11077078 DOI: 10.1093/cercor/bhae189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 04/16/2024] [Accepted: 04/19/2024] [Indexed: 05/12/2024] Open
Abstract
OBJECTIVES This retrospective study aimed to identify quantitative magnetic resonance imaging markers in the brainstem of preterm neonates with intraventricular hemorrhages. It delves into the intricate associations between quantitative brainstem magnetic resonance imaging metrics and neurodevelopmental outcomes in preterm infants with intraventricular hemorrhage, aiming to elucidate potential relationships and their clinical implications. MATERIALS AND METHODS Neuroimaging was performed on preterm neonates with intraventricular hemorrhage using a multi-dynamic multi-echo sequence to determine T1 relaxation time, T2 relaxation time, and proton density in specific brainstem regions. Neonatal outcome scores were collected using the Bayley Scales of Infant and Toddler Development. Statistical analysis aimed to explore potential correlations between magnetic resonance imaging metrics and neurodevelopmental outcomes. RESULTS Sixty preterm neonates (mean gestational age at birth 26.26 ± 2.69 wk; n = 24 [40%] females) were included. The T2 relaxation time of the midbrain exhibited significant positive correlations with cognitive (r = 0.538, P < 0.0001, Pearson's correlation), motor (r = 0.530, P < 0.0001), and language (r = 0.449, P = 0.0008) composite scores at 1 yr of age. CONCLUSION Quantitative magnetic resonance imaging can provide valuable insights into neurodevelopmental outcomes after intraventricular hemorrhage, potentially aiding in identifying at-risk neonates. Multi-dynamic multi-echo sequence sequences hold promise as an adjunct to conventional sequences, enhancing the sensitivity of neonatal magnetic resonance neuroimaging and supporting clinical decision-making for these vulnerable patients.

Eur J Pediatr 2024; 183:1629-1636. [PMID: 38189914 PMCID: PMC11001706 DOI: 10.1007/s00431-023-05387-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Revised: 12/12/2023] [Accepted: 12/13/2023] [Indexed: 01/09/2024]
Abstract
The purpose of this study is to evaluate the association of Electrical Cardiometry (EC)-derived cardiac output indexed to weight (CO) and its changes during the first 48 h in relation to adverse short-term outcome in very preterm infants. In this prospective observational study of preterm infants < 32 weeks gestational age (GA), the combined adverse outcome was defined as mortality or abnormal cranial ultrasound (any grade intracranial hemorrhage (ICH) or periventricular leukomalacia) within the first 2 weeks postnatally. Logistic regression models were used to investigate the association between median CO and outcome and mixed-effects models for the time trajectory of CO. In the absence of device-specific thresholds for low or high CO, no thresholds were used in our analysis. Fifty-three infants (median (IQR) GA 29.0 (25.4-30.6) weeks, birthweight 1020 (745-1505) g) were included in the analysis. Median CO was 241 (197-275) mL/kg/min for the adverse outcome and 198 (175-227) mL/kg/min for normal outcome (odds ratio (OR) (95% confidence interval (95% CI)), 1.01 (1.00 to 1.03); p = 0.028). After adjustment for GA, the difference was not significant (adjusted OR (95% CI), 1.01 (0.99 to 1.02); p = 0.373). CO trajectory did not differ by outcome (p = 0.352). A post hoc analysis revealed an association between CO time trajectory and ICH ≥ grade 2. Conclusions: EC-derived CO estimates within 48 h postnatally were not independently associated with brain injury (any grade) or mortality in the first 14 days of life. CO time trajectory was found to be associated with ICH ≥ grade 2. What is Known: • Bioreactance-derived cardiac output indexed to bodyweight (CO) in the transitional period has been associated with adverse short-term outcome in preterm infants. What is New: • Electrical Cardiometry (EC)-derived CO measurements in very preterm infants during the transitional period are not independently associated with adverse outcome (death or ultrasound detected brain damage) within 2 weeks postnatally. • In the first 48 h EC-derived CO increases over time and is higher in extremely preterm infants compared to very preterm and differs from previously reported bioreactance-derived CO values.

Abstract
PURPOSE This study investigated the feasibility and effectiveness of a novel, evidence-based developmental care pathway to be used by health care providers and parents in the neonatal intensive care unit (NICU) setting. The i-Rainbow is based on current evidence and responds to individual infant health status. It is not based on infant age. METHODS After development and implementation of the i-Rainbow, pre- and postimplementation nurse and parent survey data were collected and pre- and post-developmental care rates were compared. RESULTS After i-Rainbow implementation, disagreement among providers on appropriate developmental care interventions significantly decreased, total minutes of daily developmental care and swaddled holding increased significantly, and parents reported that they would recommend the tool. CONCLUSION The i-Rainbow is a unique, parent-friendly, infant-based tool that guides sensory interventions in the NICU by staging infants based on cardiorespiratory status and physiologic maturity, not age. The i-Rainbow improved the delivery of developmental care activities in our unit and was well received by parents and nurses.

Abstract
BACKGROUND Guidelines on when to screen for neonatal hyperbilirubinemia apply to infants born at 35 weeks or later of gestation. It is unknown whether infants born earlier would benefit from similar guidelines. Our objective was to examine hyperbilirubinemia screening and phototherapy prescription among early preterm infants during the first 6 days of life. METHODS We reviewed the charts of 193 infants born prior to 35 weeks of gestation who were admitted to a tertiary care NICU in Southeastern Ontario in 2018-2019. Information on total serum bilirubin (TSB) measurements over each 12-hour interval during the first six days of life and the treatment decision (no treatment, initiate, continue, or stop phototherapy) was extracted. We also examined what proportion of infants were prescribed phototherapy during each 12-hour interval. RESULTS Of 1006 TSB measurements performed over the first 6 days of life, 605 were done to determine whether phototherapy should be initiated. Treatment was prescribed in 275 instances (45%). A higher proportion of infants born prior to 28 weeks of gestation required phototherapy in the first 12 hours of life (37%) compared to those born at 28-32 weeks (20%) and 33-34 weeks (5.7%). CONCLUSIONS Our results suggest that TSB measurements are often poorly timed to detect treatment need in infants born prior to 35 weeks of gestation. This unnecessarily increases the risk of complications from phlebotomy and is an ineffective use of health care resources. There is a need to develop guidelines to optimize hyperbilirubinemia screening among early preterm infants.

Abstract
Background Brain injury (BI) is prevalent in premature infants with twin-to-twin transfusion syndrome (TTTS), while risk factors of BI in these patients remains unknown. Our study aims to discern potential risk factors that contribute to BI in premature infants with TTTS. Methods We conducted a retrospective cohort and analyzed clinical data of premature infants diagnosed with TTTS at the Northwest Women's and Children's Hospital between January 1, 2015 and January 1, 2020. Data included the infants' perinatal information, key postnatal examinations, laboratory tests, and treatments. Results Of the 84 patients enrolled in the study, 22 (26.2%) were categorized in the BI group and 62 (73.8%) in the non-BI group, based on cranial imaging. No significant differences were found at baseline between the groups in relation to the proportion of males (40.9% vs. 35.5%, P=0.845), median gestational age (weeks) [31.9 (31.5, 33.4) vs. 34.2 (31.6, 35.4), P=0.061], average weight (g) (1,676.4±567.5 vs. 1,845.2±511.7, P=0.200), maternal age (years) [29.5 (26.0, 31.0) vs. 28.5 (27.8, 31.0), P=0.656], the proportion of in-vitro fertilization (9.1% vs. 16.1%, P=0.648), cesarean sections (86.4% vs. 93.5%, P=0.549) or TTTS donor infants (50.0% vs. 51.6%, P=0.897). Multivariate logistic regression analysis indicated that invasive mechanical ventilation [invasive mechanical ventilation (IMV); odds ratio (OR) =4.365; 95% confidence interval (CI): 1.066-17.870; P=0.040], [necrotizing enterocolitis (NEC); OR =8.632; 95% CI: 1.542-48.318; P=0.014], [single intrauterine fetal demise (sIUFD); OR =14.067; 95% CI: 1.298-224.421; P=0.031], and a 5-minute Apgar score <9 (OR =4.663; 95% CI: 1.015-21.419; P=0.048) were strongly associated with BI in TTTS premature infants. Conclusions Our study identifies IMV, NEC, sIUFD, and a 5-minute Apgar score <9 as independent risk factors for BI in premature infants with TTTS.

Abstract
BACKGROUND One of the most severe perinatal lesions of the central nervous system is intraventricular hemorrhage, which often, especially in prematurely born babies with low gestational age and body weight, is complicated by posthemorrhagic hydrocephalus, which requires good early diagnosis and timely treatment. The purpose of the article is to improve the methods of diagnosis and treatment of posthemorrhagic hydrocephalus in young children. METHODS The study was conducted between 2009 and 2018 in the neurosurgical department of the City Children's Hospital No. 2 in Astana. Three groups of patients from birth to age six months were studied. During the investigation the following research methods were used: clinical and anamnestic, laboratory, instrumental, and methods of mathematical statistics. Statistical analysis was performed using the program Statistica for Windows 13.0 (StatSoft Inc. No. JPZ804I382130ARCN10-J). Patients of the main and control groups underwent various surgical interventions to relieve posthemorrhagic occlusive hydrocephalus. RESULTS It was found that the maximum number of complications develop in newborns with low gestational age and low body weight. Repeated lumbar or ventricular punctures in patients with posthemorrhagic hydrocephalus followed by external drainage are characterized by the greatest number of complications, among which infection and catheter occlusion prevail. CONCLUSIONS It has been established that the proposed algorithm for the diagnosis and treatment of patients with posthemorrhagic hydrocephalus can significantly reduce the number of complications, shorten the duration of hospital stay, reduce the percentage of long-term complications, and improve the quality of life.

Abstract
Platelets are major regulators of haemostasis and coagulation. The primary role of platelets in coagulation is to form a stable clot and stop bleeding. Studies of platelet phenotype and function in neonates and children have been restricted by the large volumes required for many common platelet function tests such as platelet aggregometry. Developmental changes in platelets have not been as well described as developmental changes in plasma coagulation proteins, and overall, platelet phenotype and function in neonates and children has been understudied when compared to adults. Recent developments in more sensitive platelet function testing methods requiring smaller blood volumes such as flow cytometry has enabled recent studies to further investigate platelet phenotype and function in neonates and children. In this review we will provide an overview of recent advances from the past five years in platelets in the context of developmental haemostasis, as well as the role of platelets in neonatal paediatric disease.

Transfontanelle photoacoustic imaging of intraventricular brain hemorrhages in live sheep. PHOTOACOUSTICS 2023; 33:100549. [PMID: 37664559 PMCID: PMC10474607 DOI: 10.1016/j.pacs.2023.100549] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Revised: 08/22/2023] [Accepted: 08/23/2023] [Indexed: 09/05/2023]
Abstract
Intraventricular (IVH) and periventricular (PVH) hemorrhages in preterm neonates are common because the periventricular blood vessels are still developing up to 36 weeks and are fragile. Currently, transfontanelle ultrasound (US) imaging is utilized for screening for IVH and PVH, largely through the anterior fontanelle. However for mild hemorrhages, inconclusive diagnoses are common, leading to failure to detect IVH/PVH or, when other clinical symptoms are present, use of second stage neuroimaging modalities requiring transport of vulnerable patients. Yet even mild IVH/PVH increases the risk of moderate-severe neurodevelopmental impairment. Here, we demonstrate the capability of transfontanelle photoacoustic imaging (TFPAI) to detect IVH and PVH in-vivo in a large animal model. TFPAI was able to detect IVH/PVH as small as 0.3 mL in volume in the brain (p < 0.05). By contrast, US was able to detect hemorrhages as small as 0.5 mL. These preliminary results suggest TFPAI could be translated into a portable bedside imaging probe for improved diagnosis of clinically relevant brain hemorrhages in neonates.

Abstract
Premature infants with germinal matrix haemorrhage-intraventricular haemorrhage (GMH-IVH) suffer from neurobehavioural deficits as they enter childhood and adolescence. Yet the underlying mechanisms remain unclear. Impaired development and function of interneurons contribute to neuropsychiatric disorders. Therefore, we hypothesized that the occurrence of IVH would reduce interneuron neurogenesis in the medial ganglionic eminence and diminish the population of parvalbumin+ and somatostatin+ cortical interneurons. Because Sonic Hedgehog promotes the production of cortical interneurons, we also postulated that the activation of Sonic Hedgehog signalling might restore neurogenesis, cortical interneuron population, and neurobehavioural function in premature newborns with IVH. These hypotheses were tested in a preterm rabbit model of IVH and autopsy samples from human preterm infants. We compared premature newborns with and without IVH for intraneuronal progenitors, cortical interneurons, transcription factors regulating neurogenesis, single-cell transcriptome of medial ganglionic eminence and neurobehavioural functions. We treated premature rabbit kits with adenovirus expressing Sonic Hedgehog (Ad-Shh) or green fluorescence protein gene to determine the effect of Sonic Hedgehog activation on the interneuron production, cortical interneuron population and neurobehaviour. We discovered that IVH reduced the number of Nkx2.1+ and Dlx2+ progenitors in the medial ganglionic eminence of both humans and rabbits by attenuating their proliferation and inducing apoptosis. Moreover, IVH decreased the population of parvalbumin+ and somatostatin+ neurons in the frontal cortex of both preterm infants and kits relative to controls. Sonic Hedgehog expression and the downstream transcription factors, including Nkx2.1, Mash1, Lhx6 and Sox6, were also reduced in kits with IVH. Consistent with these findings, single-cell transcriptomic analyses of medial ganglionic eminence identified a distinct subpopulation of cells exhibiting perturbation in genes regulating neurogenesis, ciliogenesis, mitochondrial function and MAPK signalling in rabbits with IVH. More importantly, restoration of Sonic Hedgehog level by Ad-Shh treatment ameliorated neurogenesis, cortical interneuron population and neurobehavioural function in kits with IVH. Additionally, Sonic Hedgehog activation alleviated IVH-induced inflammation and several transcriptomic changes in the medial ganglionic eminence. Taken together, IVH reduced intraneuronal production and cortical interneuron population by downregulating Sonic Hedgehog signalling in both preterm rabbits and humans. Notably, activation of Sonic Hedgehog signalling restored interneuron neurogenesis, cortical interneurons and cognitive function in rabbit kits with IVH. These findings highlight disruption in cortical interneurons in IVH and identify a novel therapeutic strategy to restore cortical interneurons and cognitive function in infants with IVH. These studies can accelerate the development of new therapies to enhance the neurodevelopmental outcome of survivors with IVH.

Zhao Y, Zhang W, Tian X. Analysis of risk factors of early intraventricular hemorrhage in very-low-birth-weight premature infants: a single center retrospective study. BMC Pregnancy Childbirth 2022; 22:890.

Abstract
BACKGROUND This study aimed to determine the risk factors of early intraventricular hemorrhage (IVH) in very-low-birth-weight (VLBW) premature infants in China to guide early interventions and improve the survival and quality of life of these infants. METHODS Data on 421 VLBW premature infants admitted to the neonatal intensive care unit of Tianjin Central Hospital of Gynecology Obstetrics between July 2017 and July 2019 were retrospectively evaluated. Data on head ultrasound results, maternal pregnancy complications, and perinatal conditions were reviewed to evaluate the association between maternal and neonatal factors and the development and severity of IVH. RESULTS Univariate analysis showed that the incidence of early IVH was significantly higher in neonates with early gestational age, delivered after spontaneous labor, low birth weight, 5-minute Apgar score ≤ 7, invasive mechanical ventilation, and early onset sepsis (χ2 = 11.087, 16.868, 4.779, 11.170, 6.655, and 6.260, respectively; P < 0.05), but it was significantly lower in the presence of gestational hypertension (χ2 = 4.373, P = 0.037). In addition, severe IVH was significantly associated with early gestational age, low birth weight, 5-minute Apgar score ≤ 7, and neonatal sepsis (χ2 = 11.599, 8.263, 11.172, and 7.749, respectively; P < 0.05). Logistic regression analysis showed that antenatal glucocorticoid use was associated with significantly reduced incidence of severe IVH (OR = 0.095, 95% CI = 0.012-0.739, P = 0.024). CONCLUSION Appropriate mode of delivery may effectively reduce the incidence of IVH in VLBW premature infants. The antenatal glucocorticoid use may also protect against severe IVH. The focus on steroid prophylaxis, mode of delivery and prevention of perinatal asphyxia should be stressed in China.

Abstract
OBJECTIVE To identify the relationship between prophylactic indomethacin (PI) administration and incidence of intraventricular hemorrhage. STUDY DESIGN A retrospective analysis of extremely premature infants <27 weeks gestational age born between January 2014 and September 2020. RESULTS A total of 421 infants were included from three of Nationwide Children's Hospital delivery centers. Of those 255 (61%) received PI. After adjustment by inverse proportionality treatment weighting (IPTW), no differences were found in incidence of intraventricular hemorrhage (IVH) at the time of the first ultrasound, 31% vs. 33% in PI and control groups respectively (p = 0.68). The rate of rise of serum creatinine from baseline to day of life four was significantly higher in the PI group (0.14 mg/dl PI and 0.03 mg/dl control, p < 0.001). CONCLUSION PI was not associated with any benefit in prevention of IVH, but is associated with adverse effects including acute rise in creatinine.

Abstract
OBJECTIVE This study was aimed to assess the incidence of and risk factors for autism spectrum disorder (ASD) among preterm infants born <29 weeks' gestational age (GA). METHODS A retrospective cohort study of infants born <29 weeks' GA admitted to two tertiary neonatal intensive care units (2009 to 2017) and followed ≥18 months corrected age (CA) at a neonatal follow-up clinic. The primary outcome was ASD, diagnosed using standardized testing or provisional diagnosis at ≥18 months CA. Patient data and 18-month CA developmental outcomes were obtained from the local Canadian Neonatal Follow Up Network database and chart review. Stepwise logistic regression assessed factors associated with ASD. RESULTS Among 300 eligible infants, 26 (8.7%) were diagnosed with confirmed and 21 (7.0%) with provisional ASD for a combined incidence of 15.7% (95% confidence interval [CI] 11.7 to 20.3). The mean follow-up duration was 3.9 ± 1.4 years and the mean age of diagnosis was 3.7 ± 1.5 years. Male sex (adjusted odds ratio [aOR] 4.63, 95% CI 2.12 to 10.10), small for gestational age status (aOR 3.03, 95% CI 1.02 to 9.01), maternal age ≥35 years at delivery (aOR 2.22, 95% CI 1.08 to 4.57) and smoking during pregnancy (aOR 5.67, 95% CI 1.86 to 17.29) were significantly associated with ASD. Among ASD infants with a complete 18-month CA developmental assessment, 46% (19/41) had no neurodevelopmental impairment (Bayley-III<70, deafness, blindness, or cerebral palsy). CONCLUSIONS ASD is common among infants born <29 weeks' GA and possibly associated with identified risk factors. Such findings emphasize the importance of ASD evaluation among infants <29 weeks' GA and for continued reporting of developmental outcomes beyond 18-months of corrected age.

Abstract
The capability of photoacoustic (PA) imaging to measure oxygen saturation through a fontanelle has been demonstrated in large animals in-vivo. We called this method, transfontanelle photoacoustic imaging (TFPAI). A surgically induced 2.5 cm diameter cranial window was created in an adult sheep skull to model the human anterior fontanelle. The performance of the TFPAI has been evaluated by comparing the PA-based predicted results against the gold standard of blood gas analyzer measurements.

Abstract
OBJECTIVE To investigate differences and calculate pooled incidence of any intraventricular haemorrhage (IVH), severe IVH (Grade III/IV, sIVH) and ventriculoperitoneal shunt (VPS) placement in preterm infants across geographical, health and economic regions stratified by gestational age (GA). DESIGN MEDLINE, Embase, CINAHL and Web of Science were searched between 2010 and 2020. Studies reporting rates of preterm infants with any IVH, sIVH and VPS by GA subgroup were included. Meta-regression was performed to determine subgroup differences between study designs and across United Nations geographical regions, WHO mortality strata and World Bank lending regions. Incidence of any IVH, sIVH and VPS by GA subgroups<25, <28, 28-31, 32-33 and 34-36 weeks were calculated using random-effects meta-analysis. RESULTS Of 6273 publications, 97 met inclusion criteria. Incidence of any IVH (37 studies 87 993 patients) was: 44.7% (95% CI 40.9% to 48.5%) for GA <25 weeks, 34.3% (95% CI 31.2% to 37.6%) for GA <28 weeks, 17.4% (95% CI 13.8% to 21.6%) for GA 28-31 weeks, 11.3% (95% CI 7.3% to 17.0%) for GA32-33 weeks and 4.9% (95% CI 1.4% to 15.2%) for GA 34-36 weeks. Incidence of sIVH (49 studies 328 562 patients) was 23.7% (95% CI 20.9% to 26.7%) for GA <25 weeks, 15.0% (95% CI 13.1% to 17.2%) for GA <28 weeks, 4.6% (95% CI 3.5% to 6.1%) for GA 28-31 weeks, 3.3% (95% CI 2.1% to 5.1%) for GA 32-33 weeks and 1.8% (95% CI 1.2% to 2.8%) for GA 34-36 weeks. Europe had lower reported incidence of any IVH and sIVH relative to North America (p<0.05). Proportion of VPS across all GA groups was 8.4% (95% CI 4.7% to 14.7%) for any IVH and 17.2% (95% CI 12.2% to 26.2%) for sIVH. Heterogeneity was high (I2 >90%) but 64%-85% of the variance was explained by GA and study inclusion criteria. CONCLUSIONS We report the first pooled estimates of IVH of prematurity by GA subgroup. There was high heterogeneity across studies suggesting a need for standardised incidence reporting guidelines.

Caffeine Restores Neuronal Damage and Inflammatory Response in a Model of Intraventricular Hemorrhage of the Preterm Newborn. Front Cell Dev Biol 2022; 10:908045.

Abstract
Germinal matrix-intraventricular hemorrhage (GM-IVH) is the most frequent intracranial hemorrhage in the preterm infant (PT). Long-term GM-IVH-associated sequelae include cerebral palsy, sensory and motor impairment, learning disabilities, or neuropsychiatric disorders. The societal and health burden associated with GM-IVH is worsened by the fact that there is no successful treatment to limit or reduce brain damage and neurodevelopment disabilities. Caffeine (Caf) is a methylxanthine that binds to adenosine receptors, regularly used to treat the apnea of prematurity. While previous studies support the beneficial effects at the brain level of Caf in PT, there are no studies that specifically focus on the role of Caf in GM-IVH. Therefore, to further understand the role of Caf in GM-IVH, we have analyzed two doses of Caf (10 and 20 mg/kg) in a murine model of the disease. We have analyzed the short (P14) and long (P70) effects of the treatment on brain atrophy and neuron wellbeing, including density, curvature, and phospho-tau/total tau ratio. We have analyzed proliferation and neurogenesis, as well as microglia and hemorrhage burdens. We have also assessed the long-term effects of Caf treatment at cognitive level. To induce GM-IVH, we have administered intraventricular collagenase to P7 CD1 mice and have analyzed these animals in the short (P14) and long (P70) term. Caf showed a general neuroprotective effect in our model of GM-IVH of the PT. In our study, Caf administration diminishes brain atrophy and ventricle enlargement. Likewise, Caf limits neuronal damage, including neurite curvature and tau phosphorylation. It also contributes to maintaining neurogenesis in the subventricular zone, a neurogenic niche that is severely affected after GM-IVH. Furthermore, Caf ameliorates small vessel bleeding and inflammation in both the cortex and the subventricular zone. Observed mitigation of brain pathological features commonly associated with GM-IVH also results in a significant improvement of learning and memory abilities in the long term. Altogether, our data support the promising effects of Caf to reduce central nervous system complications associated with GM-IVH.

Abstract
BACKGROUND The increased survival rate among very low birth weight infants has resulted in a higher risk for developing neuro-complications such as intraventricular hemorrhage (IVH), periventricular leukomalacia (PVL), and adverse neurodevelopmental outcomes. PURPOSE We examined refractory hypotension experienced within a week of life in association with severe IVH (grades 3-4) among very low birth weight infants (VLBWIs). METHOD Between Jan 2014 and Dec 2017, the clinical data of 191 VLBWIs were retrospectively chart reviewed. Of a total of 191 VLBWIs, 71.2% (136/191) had IVH, and 28.7% (55/191) had severe IVH. RESULTS The VLBWI with severe IVH group (grade 3-4) presented with a significantly lower gestational age along with higher use of postnatal hydrocortisone for refractory hypotension within a week of life. Resuscitation at delivery, pulmonary hemorrhage, neonatal seizure, and PVL were significantly more frequent in the severe IVH group (P < .05). Higher mortality occurred in the VLBWI with severe IVH group (P < .001). The multivariable logistic regression analysis consistently showed that refractory hypotension within a week of life and neonatal seizures were significantly associated with severe IVH. Those in the severe IVH and refractory hypotension groups had significantly lower composite cognitive, language, motor scores in Bayley Scales of Infant and Toddler Development III scores at corrected 18-24 months. CONCLUSION Refractory hypotension within a week of life and seizures were consistently associated with severe IVH and developmental delay at corrected 18-24 months. VLBWI who experienced refractory hypotension within a week of life may indicate a more vulnerable clinical setting with a higher risk for developmental delay.

Abstract
BACKGROUND Intraventricular hemorrhage (IVH) is a serious problem in preterm infants. Brazilian national data are unknown. OBJECTIVE To evaluate the incidence and temporal trend of IVH in very low birth weight (VLBW) preterm infants of 18 centers of the Brazilian Network on Neonatal Research. STUDY DESIGN National prospective multicenter cohort study including inborn VLBW preterm infants aged 230/7- 336/7 weeks' gestation, admitted between 2013 and 2018. The center with the mean incidence rate was used as reference. We applied two adjustments models using perinatal variables, and perinatal + neonatal diseases. RESULTS Of 6,420 infants, 1951/30.4% (range 27.1-33.8%) had IVH and the disease showed a significant trend towards an overall increase in incidence over time (p = 0.003), especially in three centers. Severe IVH (grade III or IV) occurred in 32.2% (range 29.2-34.5%) of those affected by IVH, with a stable incidence. After adjustments for perinatal variables, the differences persisted among centers: for global IVH, 7 centers had significantly lower rates (OR ranging from 0.31 to 0.62), and 2 presented rates higher than the reference center (OR ranging from 2.00 to 12.46) for severe HIV. Considering perinatal and neonatal variables, 6 centers had significantly lower rates (OR ranging from 0.36 to 0.60) for global IVH than the reference center and 3 had statistically higher rates (OR 1.72, 1.86 and 11.78) for severe forms. CONCLUSION The incidence rate of IVH in this Brazilian cohort was high and it revealed an increasing trend towards over time. The severe IVH rate was also worrisome.

Abstract
Aim The aim of this study was to investigate the associations between sodium supply, fluid volume, sodium imbalances and severe intraventricular haemorrhage (IVH) in extremely preterm (EPT) infants. Methods We used data from the EXtremely PREterm infants in Sweden Study (EXPRESS) cohort consisting of all infants born at 22 to 26 gestational weeks from 2004 to 2007 and conducted a nested case–control study. For every infant with severe IVH (grade 3 or peri‐ventricular haemorrhagic infarction), one IVH‐free control infant with the birthday closest to the case infant and matched for hospital, sex, gestational age and birth weight was selected (n = 70 case–control pairs). Results Total sodium supply and fluid volume were higher in infants with severe IVH compared with controls [daily total sodium supply until postnatal Day 2: mean ± SD (mmol/kg/day): 5.49 ± 2.53 vs. 3.95 ± 1.91, p = 0.009]. These differences were accounted for by sodium and fluid from transfused blood products. High plasma sodium concentrations or large sodium fluctuations were not associated with severe IVH. Conclusion Our results suggest a relationship between sodium‐rich transfusions of blood products and severe IVH in EPT infants. It is unclear whether this is an effect of sodium load, volume load or some other transfusion‐related factor.

Abstract
BACKGROUND Platelet transfusions (PTxs) are often given to septic preterm neonates at high platelet count thresholds in an attempt to reduce bleeding risk. However, the largest randomized controlled trial (RCT) of neonatal transfusion thresholds found higher mortality and/or major bleeding in infants transfused at higher thresholds. Using a murine model, we investigated the effects of adult PTx on neonatal sepsis-induced mortality, systemic inflammation, and platelet consumption. STUDY DESIGN AND METHODS Polymicrobial sepsis was induced via intraperitoneal injection of cecal slurry preparations (CS1, 2, 3) into P10 pups. Two hours after infection, pups were transfused with washed adult Green Flourescent Protein (GFP+) platelets or control. Weights, platelet counts, and GFP% were measured before 4 and 24 h post-infection. At 24 h, blood was collected for quantification of plasma cytokines. RESULTS The CS batches varied in 24 h mortality (11%, 73%, and 30% in CS1, 2, and 3, respectively), due to differences in bacterial composition. PTx had differential effects on sepsis-induced mortality and systemic inflammatory cytokines, increasing both in mice infected with CS1 (low mortality) and decreasing both in mice infected with CS2 and 3. In a mathematical model of platelet kinetics, the consumption of transfused adult platelets was higher than that of endogenous neonatal platelets, regardless of CS batch. DISCUSSION Our findings support the hypothesis that transfused adult platelets are consumed faster than endogenous neonatal platelets in sepsis and demonstrate that PTx can enhance or attenuate neonatal inflammation and mortality in a model of murine polymicrobial sepsis, depending on the composition of the inoculum and/or the severity of sepsis.

Abstract
Peri-intraventricular hemorrhage (PIVH) is a serious condition for preterm infants, caused by traumatic or spontaneous rupture of the germinal matrix (GM) capillary network in the cerebral ventricles. It is a common source of morbidity and mortality in neonates, and risk correlates with earlier delivery, low birth weight, maternal-fetal infection, and vital sign derangements, among others. PIVH typically occurs in the first 72 h of life, and symptoms, when present, manifest most commonly within the first week of life. Prevention remains the primary goal in management, predominantly via prolonging of gestation. Current therapy protocols are center-dependent without consistent consensus guidelines, but infant positioning, homeostatic stabilization, and neuroprotection offer potential options. In this update of pharmacologic neuroprotective therapies for PIVH, we highlight commonly utilized therapies and review the investigative literature. Further multi-institutional clinical trials and basic research studies are required.

Abstract
OBJECTIVE Neonatal intraventricular hemorrhage (IVH) is a major cause of mortality and morbidity, particularly following premature birth. Even after the acute phase, posthemorrhagic hydrocephalus is a long-term complication, frequently requiring permanent ventriculoperitoneal shunt (VPS) placement. Currently, there are no risk classification methods integrating the constellation of clinical data to predict short- and long-term prognosis in neonatal IVH. To address this need, the authors developed a two-part machine learning approach for predicting short- and long-term outcomes after diagnosis of neonatal IVH. Integrating both maternal and neonatal characteristics, they developed a binary classifier to predict short-term mortality risk and a clinical scale to predict the long-term risk of VPS placement. METHODS Neonates with IVH were identified from the Optum Clinformatics Data Mart administrative claims database. Matched maternal and childbirth characteristics were obtained for all patients. The primary endpoints of interest were short-term (30 day) mortality and long-term VPS placement. Classification of short-term mortality risk was evaluated using 5 different machine learning approaches and the best-performing method was validated using a withheld validation subset. Prediction of long-term shunt risk was performed using a multivariable Cox regression model with stepwise variable selection, which was subsequently converted to an easily applied integer risk scale. RESULTS A total of 5926 neonates with IVH were identified. Most patients were born before 32 weeks' gestation (67.2%) and with low birth weight (81.2%). Empirical 30-day mortality risk was 10.9% across all IVH grades and highest among grade IV IVH (34.3%). Among the neonates who survived > 30 days, actuarial 12-month postdiagnosis risk of shunt placement was 5.4% across all IVH grades and 31.3% for grade IV IVH. The optimal short-term risk classifier was a random forest model achieving an area under the receiver operating characteristic curve of 0.882 with important predictors ranging from gestational age to diverse comorbid medical conditions. Selected features for long-term shunt risk stratification were IVH grade, respiratory distress syndrome, disseminated intravascular coagulation, and maternal preeclampsia or eclampsia. An integer risk scale, termed the Shunt Prediction After IVH in Neonates (SPAIN) scale, was developed from these 4 features, which, evaluated on withheld cases, demonstrated improved risk stratification compared with IVH grade alone (Harrell's concordance index 0.869 vs 0.852). CONCLUSIONS In a large cohort of neonates with IVH, the authors developed a two-pronged, integrated, risk classification approach to anticipate short-term mortality and long-term shunt risk. The application of such approaches may improve the prognostication of outcomes and identification of higher-risk individuals who warrant careful surveillance and early intervention.

Abstract
BACKGROUND Summary data indicate that it has increased attention to the study of the role of the folate cycle and the genes encoding its key components in the complicated course of the neonatal period in premature infants. Therefore, the aim of our study was to investigate the relationship of folate cycle gene variants with the features of the neonatal course in premature infants with severe intraventricular hemorrhages (IVH). METHODS The study included 24 preterm infants with with IVHs of 3d and 4th degree that received standard clinical, laboratory and instrumental examination. RESULTS Apgar scores at 1 and 5 minutes were significantly lower in patients with AA genotype according to variant A1298C of the MTHFR gene. The concentration of total protein on 6th day after birth was negatively correlated with the A66G variant of the MTRR gene. The mean concentration of ionized calcium in the first day after birth was higher in the subgroup of patients with the AA genotype (according to variant A1298C of the MTHFR gene). In the subgroup of patients requiring mechanical ventilation, the frequency of AA genotype according to variant A2756G of the MTR gene was significantly increased. The presence of respiratory disorders and oxygen dependence was negatively correlated with variant A1298C MTHFR. The day of surfactant administration was positively correlated with variant A1298C of the MTHFR gene. CONCLUSION The results of this study indicate that gene variants MTHFR (C677T, A1298C), MTRR (A66G), MTR (A2756G), RFC1 (G80A) may affect the neonatal course in premature infants with severe IVH.

Abstract
Germinal matrix hemorrhage-intraventricular hemorrhage (GMH-IVH) is a particular type of intracranial hemorrhage that affects the preterm population. GMH-IVH originates from bleeding within the highly vascular area near the center of the brain known as the germinal matrix. The pathogenesis of GMH-IVH is unclear; it is likely related to hemodynamic changes and fluctuations in cerebral blood flow within a fragile developing brain. Cranial ultrasound is the primary diagnostic test and reveals the degree of GMH-IVH based on a grading system. Management includes prevention of preterm delivery with meticulous antenatal and postnatal preventative strategies. This article discusses current evidence specific to the pathogenesis, risk factors, diagnosis, grading scales, and management approaches with GMH-IVH in preterm infants.

Abstract
OBJECTIVE To use cluster analysis to identify discrete phenotypic groups of extremely preterm infants. DESIGN Secondary analysis of a retrospective whole population study. SETTING All neonatal units in England between 2014 and 2019. PARTICIPANTS Infants live-born at less than 28 weeks of gestation and admitted to a neonatal unit. INTERVENTIONS K-means cluster analysis was performed with the gestational age, Apgar score at 5 min and duration of mechanical ventilation as input variables. PRIMARY AND SECONDARY OUTCOME MEASURES Bronchopulmonary dysplasia, discharge on home oxygen, intraventricular haemorrhage, death before discharge from neonatal care. RESULTS Ten thousand one hundred and ninety-seven infants (53% male) were classified into four clusters: Cluster 1 contained infants with intermediate gestation and duration of ventilation and had an intermediate mortality and incidence of bronchopulmonary dysplasia. Cluster 2 contained infants with the highest gestation, a shorter duration of ventilation and the lowest mortality. Cluster 3 contained infants with the lowest Apgar score and highest mortality and incidence of intraventricular haemorrhage. Cluster 4 contained infants with the lowest gestation, longest duration of ventilation and highest incidence of bronchopulmonary dysplasia. CONCLUSION Clinical parameters can classify extremely preterm infants into discrete phenotypic groups with differing subsequent neonatal outcomes.

Abstract
Very low birthweight (VLBW) infants are at risk of intraventricular haemorrhage (IVH) and delayed closure of ductus arteriosus. We investigated mean arterially recorded blood pressure (MAP) changes during the first day of life in VLBW infants as potential risk factors for a patent ductus arteriosus (PDA) and IVH. This retrospective cohort study exploring MAP changes during adaption and risk factors for a PDA and IVH comprised 844 VLBW infants admitted to the Helsinki University Children’s Hospital during 2005–2013. For each infant, we investigated 600 time-points of MAP recorded 4–24 hours after birth. Based on blood pressure patterns revealed by a data-driven method, we divided the infants into two groups. Group 1 (n = 327, mean birthweight = 1019 g, mean gestational age = 28 + 1/7 weeks) consisted of infants whose mean MAP was lower at 18–24 hours than at 4–10 hours after birth. Group 2 (n = 517, mean birthweight = 1070 g, mean gestational age = 28 + 5/7 weeks) included infants with a higher mean MAP at 18–24 hours than at 4–10 hours after birth. We used the group assignments, MAP, gestational age at birth, relative size for gestational age, surfactant administration, inotrope usage, invasive ventilation, presence of respiratory distress syndrome or sepsis, fluid intake, and administration of antenatal steroids to predict the occurrence of IVH and use of pharmacological or surgical therapy for a PDA before 42 weeks of gestational age. Infants whose mean MAP is lower at 18–24 hours than at 4–10 hours after birth are more likely to undergo surgical ligation of a PDA (odds ratio = 2.1; CI 1.14–3.89; p = 0.018) and to suffer from IVH (odds ratio = 1.83; CI 1.23–2.72; p = 0.003).

Post-Hemorrhagic Hydrocephalus and Outcomes Amongst Neonates With Intraventricular Hemorrhage: A Systematic Review and Pooled Analysis. Cureus 2021; 13:e18877. [PMID: 34804726 PMCID: PMC8599435 DOI: 10.7759/cureus.18877] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2020] [Accepted: 10/13/2021] [Indexed: 11/18/2022] Open
Abstract
Introduction Intraventricular hemorrhage (IVH) is a common cause of morbidity and mortality in preterm neonates. IVH leads to complications such as posthemorrhagic hydrocephalus (PHH), which commonly occurs in neonates with a more severe degree of IVH. Hence, we aimed to evaluate the characteristics and outcomes of PHH in neonates with IVH. Methods We performed a systematic review of cases reported from January 1978 to December 2020 through the PubMed database, using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the keywords 'intraventricular hemorrhage,' 'cerebral intraventricular hemorrhage,' and 'newborn.' A total of 79 articles were considered for analysis, and data on neonatal and maternal characteristics and outcomes were collected. The analysis was performed by using the χ2 test, Wilcoxon rank-sum test, and multivariate logistic regression model. Results We analyzed a total of 101 IVH cases, 54.5% were male and 62.4% preterm. Thirteen point nine percent (13.9%) presented with grade I, 35.6% grade II, and grade III respectively, and 8% grade IV IVH. Among the 59 (58.4%) neonates with PHH, 33.6% had resolved PHH and 24.8% had unresolved. In adjusted regression analysis, we found that neonates with resolved PHH have lower odds of having neurodevelopmental delay (OR:0.15, 95%CI:0.03-0.74; p=0.02) and death (OR:0.9;95%CI:0.01-0.99; p=0.049) as compared to unresolved PHH. Conclusion Our study showed that neonates with resolved PHH have a statistically significant lower risk of neurodevelopmental delay (NDD) and mortality. Future studies should be planned to evaluate the role of treatment and its effect on outcomes in IVH neonates with PHH as a complication.

Abstract
Germinal matrix hemorrhage-intraventricular hemorrhage (GMH-IVH) remains an important cause of brain injury in preterm infants, and is associated with high rates of mortality and adverse neurodevelopmental outcomes, despite the recent advances in perinatal care. Close neuroimaging is recommended for both the detection of GMH-IVH and for the follow-up of serious complications, such as post-hemorrhagic ventricular dilatation (PHVD). Although the question when best to treat PHVD remains a matter of debate, recent literature on this topic shows that later timing of interventions predicted higher rates of neurodevelopmental impairment, emphasizing the importance of a well-structured neuroimaging protocol and timely interventions. In this guideline, pathophysiologic mechanisms, preventive measures, and clinical presentations of GMH-IVH and PHVD will be presented, and a neuroimaging protocol as well as an optimal treatment approach will be proposed in light of the recent literature.

Abstract
Bronchopulmonary dysplasia is a chronic pulmonary disease with a high incidence in premature infants, and there is still no effective treatment. The purpose of our study was to analyze the association between the use of probiotics and BPD in premature infants. We retrospectively collected clinical data of infants with gestational age < 32 weeks admitted to the NICU of The First Hospital of Jilin University from January 1, 2019 to March 31, 2020. Demographic and clinicopathological data of the inclusion population were collected. The outcome was the incidence of BPD or death. The χ2 tests was used to compare the categorical variables. The t test and non-parametric Wilcoxon rank-sum test were used to compare the continuous data. Univariate and multivariate logistic regression were used to analyze the association between probiotics and BPD. A total of 318 newborns met the inclusion criteria, of which 94 received probiotics and 224 received no probiotics. There were 16 deaths and 115 newborns with BPD in the included population. The results of univariate analysis showed differences in the maternal diabetes, the proportion of systemic antibiotics given to mother within 24 h before birth, the receiving rate of invasive mechanical ventilation, the prevalence of BPD/death, PDA, RDS and Ivh between newborns with and without probiotics (p < 0.05); The results of unadjusted univariate logistic regression model showed that probiotic (OR 0.034, 95% CI 0.012-0.096) was the factor affecting BPD in preterm infants (p < 0.05). Multivariate logistic regression result (OR 0.037, 95% CI 0.013-0.105) was consistent with univariate analysis (P < 0.001). Probiotics are associated with a reduced risk of BPD in preterm infants < 32 weeks of age. More prospective studies with large samples are still needed.

Abstract
Cranial ultrasound examinations are routinely performed in very preterm neonates. There is no widespread agreement on the optimal timing of these examinations. This review examines screening protocols and recommendations available for the timing of cranial ultrasound examinations in preterm neonates born before 32 wk of gestation. A systematic search was performed to find published screening protocols, and 18 articles were included in the final review. The protocols varied in their recommendations on timing, although at least one examination in the first week of life was universally recommended. The recommended timing for a "late" or final ultrasound examination was variable, and included at 6 wks of postnatal age, term-equivalent age or hospital discharge. There was no agreement as to whether weekly or fortnightly sequential ultrasound imaging should be performed after the first week of life. Further studies are required to establish an optimal protocol for these very preterm neonates to improve detection and monitoring of brain injuries.

Abstract
OBJECTIVES The early detection of preterm infants (PI) at risk for intraventricular hemorrhage (IVH) and neurological sequelae still constitutes an unsolved issue. We aimed at validating the role of S100B protein in the early diagnosis and prognosis of IVH in PI by means of cerebral ultrasound (CUS) and magnetic resonance imaging (MRI) today considered standard of care procedures. METHODS We conducted an observational case-control study in 216 PI of whom 36 with IVH and 180 controls. Standard clinical, laboratory, radiological monitoring procedures and S100B urine measurement were performed at four time-points (first void, 24, 48, 96 h) after birth. Cerebral MRI was performed at 40-42 weeks of corrected gestational age. RESULTS Elevated (p<0.001, for all) S100B levels were observed in the IVH group at all monitoring time-point particularly at first void when standard monitoring procedures were still silent or unavailable. S100B measured at first void correlated (p<0.001) with the grade of hemorrhage by means of CUS and with the site and extension of neurological lesion (p<0.001, for all) as assessed by MRI. CONCLUSIONS The present results showing a correlation among S100B and CUS and MRI offer additional support to the inclusion of the protein in clinical daily management of cases at risk for IVH and adverse neurological outcome. The findings open the way to further investigations in PI aimed at validating new neurobiomarkers by means of S100B.

Abstract
OBJECTIVE To compare in-hospital outcomes after umbilical cord milking vs delayed cord clamping among infants <29 weeks of gestation. STUDY DESIGN Multicenter retrospective study of infants born <29 weeks of gestation from 2016 to 2018 without congenital anomalies who received active treatment at delivery and were exposed to umbilical cord milking or delayed cord clamping. The primary outcome was mortality or severe (grade III or IV) intraventricular hemorrhage (IVH) by 36 weeks of postmenstrual age (PMA). Secondary outcomes assessed at 36 weeks of PMA were mortality, severe IVH, any IVH or mortality, and a composite of mortality or major morbidity. Outcomes were assessed using multivariable regression, incorporating mortality risk factors identified a priori, confounders, and center. A prespecified, exploratory analysis evaluated severe IVH in 2 gestational age strata, 22-246/7 and 25-286/7 weeks. RESULTS Among 1834 infants, 23.6% were exposed to umbilical cord milking and 76.4% to delayed cord clamping. The primary outcome, mortality or severe IVH, occurred in 21.1% of infants: 28.3% exposed to umbilical cord milking and 19.1% exposed to delayed cord clamping, with an aOR that was similar between groups (aOR 1.45, 95% CI 0.93, 2.26). Infants exposed to umbilical cord milking had higher odds of severe IVH (19.8% umbilical cord milking vs 11.8% delayed cord clamping, aOR 1.70 95% CI 1.20, 2.43), as did the 25-286/7 week stratum (14.8% umbilical cord milking vs 7.4% delayed cord clamping, aOR 1.89 95% CI 1.22, 2.95). Other secondary outcomes were similar between groups. CONCLUSIONS This analysis of extremely preterm infants suggests that delayed cord clamping is the preferred practice for placental transfusion, as umbilical cord milking exposure was associated with an increase in the adverse outcome of severe IVH.

Abstract
OBJECTIVE Intraventricular hemorrhage (IVH) is a complication of prematurity. Grades III and IV IVH lead to significant morbidity, but mounting evidence shows low-grade IVH (grades I-II) may be associated with adverse sequelae. Head ultrasounds (HUS) are used to screen infants for IVH but may miss low-grade IVH. Our study compared the results of HUS around 7 days of age to susceptibility-weighted imaging (SWI) obtained at term-corrected age in infants born at <30 wGA. STUDY DESIGN Infants <30 weeks gestational age (GA) with an HUS and MRI at admission to UF Health were identified by a retrospective chart review. Images were re-read by a pediatric neuroradiologist. RESULTS Ninety-four infants with a mean GA of 25.8 weeks were identified. Of those with normal HUS, 50% had low-grade IVH on the term-corrected MRI. CONCLUSIONS HUS are effective for screening for high-grade IVH. SWI is more sensitive in identifying low-grade IVH.

Abstract
Germinal matrix-intraventricular hemorrhage (GM-IVH) is a common intracranial complication in preterm infants, especially those born before 32 weeks of gestation and very-low-birth-weight infants. Hemorrhage originates in the fragile capillary network of the subependymal germinal matrix of the developing brain and may disrupt the ependymal lining and progress into the lateral cerebral ventricle. GM-IVH is associated with increased mortality and abnormal neurodevelopmental outcomes such as posthemorrhagic hydrocephalus, cerebral palsy, epilepsy, severe cognitive impairment, and visual and hearing impairment. Most affected neonates are asymptomatic, and thus, diagnosis is usually made using real-time transfontanellar ultrasound. The present review provides a synopsis of the pathogenesis, grading, incidence, risk factors, and diagnosis of GM-IVH in preterm neonates. We explore brief literature related to outcomes, management interventions, and pharmacological and nonpharmacological prevention strategies for GM-IVH and posthemorrhagic hydrocephalus.

Abstract
OBJECTIVE Intra-ventricular hemorrhage (IVH) is the leading cause of mortality and disability in premature neonates. The present study aimed to determine the frequency of IVH and its risk factors in the premature newborns admitted to the Neonatal Intensive Care Unit (NICU)at Fatemieh Hospital in Hamadan, Iran, in 2016. METHODS & MATERIALS This retrospective cross-sectional study was conducted on178 neonates with a gestational age of ≤ 32 weeks admitted to Fatemieh Hospital affiliated to the Hamadan University of Medical Sciences, Hamadan, Iran, in 2016. The study population was selected using the census method. The newborns were subjected to cranial ultrasound on the seventh day of life, and they were assigned into two case and control groups (namely neonates with IVH and those without IVH, respectively). Intra- ventricular hemorrhage was classified into four grades regarding Papile classification. The patients' demographic specifications, including 1- and 5-minute Apgar scores, type of delivery, birth weight, use of mechanical ventilation, prenatal corticosteroid, gestational age, and some complications (e.g., Pneumothorax), were collected using a checklist. The data were analyzed using SPSS software version 16. RESULTS According to the results, the prevalence of IVH in premature infants admitted to NICU was approximately 20%, and 61.2% of the neonates were male. The participants' mean gestational age was 30.39 weeks. The comparison of delivery type between the case and control groups revealed no significant difference (P=0.197). Furthermore, there was a significant difference between the two groups in terms of their need for mechanical ventilation (P=0.03), Pneumothorax(P=0.001), and 5-minute Apgar scores (P=0.04). Moreover, the incidence of IVH had a significant relationship with the mean gestational age (P=0.001) and birth weight (P=0.04). CONCLUSION According to the findings, the premature newborns admitted to the NICU revealed a relatively high prevalence of IVH. The condition is aggravated in preterm neonates by some factors such as low birth weight, 5-minute Apgar score, gestational age, and the need for mechanical ventilation.

Abstract
BACKGROUND Intraventricular hemorrhage (IVH) is a common complication in preterm infants that has poor outcomes, especially in severe cases, and there are currently no widely accepted effective treatments. Erythropoietin has been shown to be neuroprotective in neonatal brain injury. OBJECTIVE The objective of this study was to evaluate the protective effect of repeated low-dose recombinant human erythropoietin (rhEPO) in preterm infants with IVH. METHODS This was a single-blinded prospective randomized controlled trial. Preterm infants ≤ 32 weeks gestational age who were diagnosed with IVH within 72 h after birth were randomized to receive rhEPO 500 IU/kg or placebo (equivalent volume of saline) every other day for 2 weeks. The primary outcome was death or neurological disability assessed at 18 months of corrected age. RESULTS A total of 316 eligible infants were included in the study, with 157 in the rhEPO group and 159 in the placebo group. Although no significant differences in mortality (p = 0.176) or incidence of neurological disability (p = 0.055) separately at 18 months of corrected age were seen between the rhEPO and placebo groups, significantly fewer infants had poor outcomes (death and neurological disability) in the rhEPO group: 14.9 vs. 26.4%; odds ratio (OR) 0.398; 95% confidence interval (CI) 0.199-0.796; p = 0.009. In addition, the incidence of Mental Development Index scores of < 70 was lower in the rhEPO group than in the placebo group: 7.2 vs. 15.3%; OR 0.326; 95% CI 0.122-0.875; p = 0.026. CONCLUSIONS Treatment with repeated low-dose rhEPO improved outcomes in preterm infants with IVH. TRIAL REGISTRATION The study was retrospectively registered on ClinicalTrials.gov on 16 April 2019 (NCT03914690).

Germinal Matrix-Intraventricular Hemorrhage of the Preterm Newborn and Preclinical Models: Inflammatory Considerations. Int J Mol Sci 2020; 21:ijms21218343. [PMID: 33172205 PMCID: PMC7664434 DOI: 10.3390/ijms21218343] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2020] [Revised: 10/28/2020] [Accepted: 10/30/2020] [Indexed: 12/14/2022] Open
Abstract
The germinal matrix-intraventricular hemorrhage (GM-IVH) is one of the most important complications of the preterm newborn. Since these children are born at a critical time in brain development, they can develop short and long term neurological, sensory, cognitive and motor disabilities depending on the severity of the GM-IVH. In addition, hemorrhage triggers a microglia-mediated inflammatory response that damages the tissue adjacent to the injury. Nevertheless, a neuroprotective and neuroreparative role of the microglia has also been described, suggesting that neonatal microglia may have unique functions. While the implication of the inflammatory process in GM-IVH is well established, the difficulty to access a very delicate population has lead to the development of animal models that resemble the pathological features of GM-IVH. Genetically modified models and lesions induced by local administration of glycerol, collagenase or blood have been used to study associated inflammatory mechanisms as well as therapeutic targets. In the present study we review the GM-IVH complications, with special interest in inflammatory response and the role of microglia, both in patients and animal models, and we analyze specific proteins and cytokines that are currently under study as feasible predictors of GM-IVH evolution and prognosis.

Abstract
Neuroimaging of the preterm infant is a common assessment performed in the NICU. Timely and focused studies can be used for diagnostic, therapeutic, and prognostic information. However, significant variability exists among neonatal units as to which modalities are used and when imaging studies are obtained. Appropriate timing and selection of neuroimaging studies can help identify neonates with brain injury who may require therapeutic intervention or who may be at risk for neurodevelopmental impairment. This clinical report reviews the different modalities of imaging broadly available to the clinician. Evidence-based indications for each modality, optimal timing of examinations, and prognostic value are discussed.

Abstract
OBJECTIVES Renal development is impaired in fetal growth restriction (FGR). Renal size can be considered a surrogate of renal function in childhood, and could be impaired in that condition. Our aim was to evaluate the ratio of total renal volume, measured by three-dimensional ultrasound, to estimated fetal weight (TRV/EFW) among fetuses with and without growth restriction. Furthermore, we correlated TRV/EFW with fetal Doppler velocimetry and renal vascularization indexes and evaluated the association of renal volume and vascular parameters with adverse neonatal events in growth-restricted fetuses. METHODS In a retrospective cohort, TRV and renal vascularization of growth-restricted and normal fetuses were evaluated by three-dimensional ultrasonography and VOCAL technique. Independent samples t-tests and Mann-Whitney test were used for comparisons between groups. Logistic regression model was applied to evaluate the association between renal characteristics and adverse neonatal events. RESULTS Seventy-one growth-restricted fetuses were compared to 194 controls. The TRV/EFW was lower in the growth-restricted group (P < .001). In our sample, this ratio did not correlate with Doppler velocimetry parameters, renal vascular indexes or any adverse neonatal events. CONCLUSION The TRV/EFW ratio is decreased in FGR. Further studies are needed to investigate the association of this ratio with long-term renal outcomes.

Abstract
Mesenchymal stromal cells (MSCs) can be derived from various tissue sources, such as the bone marrow (BMSCs), adipose tissue (ADSCs), umbilical cord (UC-MSCs) and umbilical cord blood (UCB-MSCs). Clinical trials have been conducted to investigate the potential of MSCs in ameliorating neonatal diseases, including bronchopulmonary dysplasia (BPD), intraventricular hemorrhage (IVH) and necrotizing enterocolitis (NEC). In preclinical studies, MSC therapy has been tested for the treatment of various neonatal diseases affecting the heart, eye, gut, and brain as well as sepsis. Up to date, the number of clinical trials using MSCs to treat neonatal diseases is still limited. The data reported thus far positioned MSC therapy as safe with positive outcomes. However, most of these trials are still preliminary and generally smaller in scale. Larger trials with more appropriate controls and a longer follow-up period need to be conducted to prove the safety and efficacy of the therapy more conclusively. This review discusses the current application of MSCs in treating neonatal diseases, its mechanism of action and future direction of this novel therapy, including the potential of using MSC-derived extracellular vesicles instead of the cells to treat various clinical conditions in the newborn.

Abstract
The purpose of this study was to evaluate the impact of implementing a care bundle for preventing peri-intraventricular hemorrhage (PIVH) in preterm newborns. A longitudinal, quantitative, quasi-experimental study was conducted with preterm newborns from a neonatal unit. The study was divided into 2 stages: the first consisted of a retrospective cohort of newborns (control group) not exposed to the bundle, and the second consisted of 5 practical steps of implementing a care bundle for preventing PIVH in eligible newborns. The results show that a significant reduction in PIVH occurred, from 34.8% before the intervention to 26.3% after application of the bundle. Also, after implementation of the bundle, there was a reduction in the severe forms of PIVH in the newborns who presented with hemorrhage compared with the control group. The study shows how the use of a low-cost and easy operationalization tool can contribute to the health of preterm newborns. It was found that the bundle is directly related to the decrease in the incidence of PIVH. The results may contribute to the improvement in care quality, thus promoting safe care for premature newborns.

Abstract
Objective: This study aims to analyze the effect of advanced maternal age (>35 years old) in maternal and perinatal outcomes of preeclampsia women. Materials and methods: This is a retrospective cross-sectional study involved all women who were diagnosed with preeclampsia at Universitas Airlangga Hospital (Surabaya, Indonesia) between January 2016 until May 2017. The participant was divided into two groups based on maternal ages: the first group was women older than 35 years old (advanced maternal age - AMA), and the other group was 20-34 years old (reproductive age - RA). The primary outcomes of this study were the maternal and perinatal outcome. Results: There were a total of 43 AMA preeclampsia women and 105 RA preeclampsia women. The AMA preeclampsia group had a higher proportion of poor maternal outcome (the occurence of any complication: pulmonary edema, HELLP syndrome, visual impairment, post partum hemorrhage, and eclampsia) compared to RA preeclampsia group (60,5% vs 33,3%, p = 0,002; OR 3,059, CI 1,469-6,371). There was no significant difference in the other maternal complications such as HELLP syndrome, pulmonary oedema, and eclampsia. The only difference was the occurrence of postpartum haemorrhage which was higher in the AMA group (16,3% vs 4,8%, p = 0,02; OR 3,889, CI 1,161-13,031). The prevalence of cesarean delivery was more common in AMA group (53,3% vs 28,6%, p = 0,004; OR 2.825, CI 1.380-5.988). The AMA preeclampsia women also had poorer perinatal outcomes compared to the RA group (81,4% vs 59%, p = 0,009; OR 3.034 CI 1.283-7.177). AMA women had a higher risk of perinatal complication such as prematurity (OR 3.266 CI 1.269-8.406), IUGR (OR 4.474 CI 1.019-19.634), asphyxia (OR 4.263 CI 2.004-9.069), and infection (OR 2.138 CI 1.040-4.393). Conclusion: Advanced maternal age increases the risk of poorer maternal and neonatal outcomes in preeclampsia patients. The addition of advanced maternal ages in preeclampsia should raise the awareness of the health provider, tighter monitoring, complete screening and early intervention if needed to minimize the risk of complications.

Abstract
Background Intraventricular hemorrhage (IVH) is a serious complication of premature (<32 weeks) deliveries, especially in very-low-birth-weight (VLBW; <1500 g) neonates. Infants developing severe IVH are more prone to long-term developmental disabilities. Although 62%–79% of women in Saudi Arabia receive antenatal steroids, IVH incidence remains high. We analyzed the risk factors for IVH in preterm VLBW neonates in the central region of Saudi Arabia. Methods We included premature infants with IVH (n = 108) and gestational age- and birth weight-matched control group infants (n = 108) admitted to our neonatal intensive care unit. Cases were divided into mild (grades I and II; n = 56) and severe (grades III and IV; n = 52) IVH groups. Association of IVH with risk factors in the first week of life was investigated. Results The following risk factors were associated with severe IVH: lack of antenatal steroid administration (P < .001), pulmonary hemorrhage (P = .023), inotrope use (P = .032), neonatal hydrocortisone administration (P = .001), and patent ductus arteriosus (PDA) (P = .005). Multivariable logistic regression analysis revealed the following to be significant: lack of antenatal dexamethasone (adjusted odds ratio [aOR]: 0.219, 95% confidence interval [95% CI] 0.087–0.546), neonatal hydrocortisone administration (aOR: 3.519, 95% CI 1.204–10.281), and PDA (aOR: 2.718, 95% CI 1.024–7.210). Low hematocrit in the first 3 days of life was significantly associated with severe IVH (all P < .01). Conclusions Failure to receive antenatal dexamethasone, PDA, hydrocortisone administration for neonatal hypotension, and low hematocrit in the first 3 days of life was associated with severe IVH in VLBW neonates. Clinicians and healthcare policy makers should consider these factors during decision-making.

Abstract
AIM To answer the clinical question 'In infants about to be delivered and admitted to neonatal units, what clinical practice strategies, compared to standard care, have been shown to decrease incidence rates of intraventricular haemorrhage (IVH)?' METHODS MEDLINE via Ovid (1943 to 5 January 2018), Embase via Ovid (1974 to 5 January 2018) and the Cochrane Library (5 January 2018) were searched for relevant articles. RESULTS A total of 478 articles, after the removal of duplicates, were found and screened by title and abstract. Forty full-text articles were subsequently reviewed, and 19 were included as relevant to the structured clinical question. An additional article was included based on expert advice. CONCLUSION There are various levels of research evidence for clinical practice strategies to decrease the incidence rates of IVH. Higher-quality evidence suggests that antenatal corticosteroids decrease the rates of IVH, and multiple evidence-based intervention bundles implemented in the neonatal unit are associated with decreased rates of IVH.

Abstract
Germinal matrix hemorrhage-intraventricular hemorrhage (IVH) is the most common form of brain injury in preterm infants. Although severe IVH has declined over the years, it still affects approximately 6% of infants born before 32 weeks of gestation. Most IVH cases are detectable by the first 24 hours after birth; therefore interventions to prevent IVH should focus on antenatal management for pregnant women and delivery room management. Obstetrical interventions, including antenatal corticosteroids, maternal rather than infant transport, and possibly elective cesarean delivery have been associated with a decreased risk of IVH. Neonatal interventions in the delivery room, including delayed cord clamping or umbilical cord milking, maintaining normothermia, avoiding fluctuations in cerebral blood flow, and optimal ventilation management are associated with a decreased risk of IVH. Multiple clinical trials are under way to further identify IVH risk factors, ability to monitor or predict IVH, and ideally prevent IVH altogether. This discussion will focus on reviewing current obstetric and neonatal management practices and their associations with germinal matrix hemorrhage-IVH.

Abstract
OBJECTIVE To determine differences in severe intraventricular hemorrhage (IVH) between very-low-birth-weight (≤1500 g, VLBW) infants born to mothers with and without hypertensive disorders (HD). DESIGN/METHODS Retrospective analysis from the Optum Neonatal Database. The primary outcome of interest was severe IVH (grade 3 or 4). Secondary outcomes included other neonatal morbidities, mortality, and length of hospitalization. Outcomes were compared between VLBW infants born to mothers with and without HD. RESULTS A total of 5456 infants met inclusion criteria. After multivariable regression analysis, risks of severe IVH and bronchopulmonary dysplasia (BPD) were lower ([OR 0.42, 95% CI 0.33-0.89, p = 0.01] and [OR 0.75, 95% CI 0.58-0.97, p = 0.03], respectively) and median length of hospitalization was decreased in the HD group (49 versus 61 days, p < 0.001). CONCLUSIONS VLBW infants born to mothers with HD have a decreased risk of severe IVH, BPD, and a shorter duration of hospitalization.

Abstract
PURPOSE Intraventricular hemorrhage is the most important adverse neurologic event for preterm and very low weight birth infants in the neonatal period. This pathology can lead to various delays in motor, language, and cognition development. The aim of this article is to give an overview of the knowledge in diagnosis, classification, and treatment options of this pathology. METHOD A systematic review has been made. RESULTS The cranial ultrasound can be used to identify the hemorrhage and grade it according to the modified Papile grading system. There is no standardized protocol of intervention as there are controversial results on which of the temporizing neurosurgical procedures is best and about the appropriate parameters to consider a conversion to ventriculoperitoneal shunt. However, it has been established that the most important prognosis factor is the involvement and damage of the white matter. CONCLUSION More evidence is required to create a standardized protocol that can ensure the best possible outcome for these patients.

Abstract
OBJECTIVE To investigate the risk factors for brain injury in preterm infants by a multicenter epidemiological investigation of brain injury in hospitalized preterm infants in Anhui, China. METHODS Preterm infants who were hospitalized in the department of neonatology in 9 hospitals of Anhui Neonatal Collaboration Network between January 2016 and January 2017 were enrolled as subjects. The data of maternal pregnancy and clinical data of preterm infants were collected, and the logistic regression model was used to analyze the risk factors for brain injury in preterm infants. RESULTS A total of 3 378 preterm infants were enrolled. Of the 3 378 preterm infants, 798 (23.56%) had periventricular-intraventricular hemorrhage (PVH-IVH), and 88 (2.60%) had periventricular leukomalacia (PVL). Intrauterine distress, anemia, hypoglycemia and necrotizing enterocolitis (NEC) were risk factors for PVH-IVH (OR=1.310, 1.591, 1.835, and 3.310 respectively; P<0.05), while a higher gestational age was a protective factor against PVH-IVH (OR=0.671, P<0.05). PVH-IVH, NEC and mechanical ventilation were risk factors for PVL (OR=4.017, 3.018, and 2.166 respectively; P<0.05), and female sex and use of pulmonary surfactant were protective factors against PVL (OR=0.514 and 0.418 respectively; P<0.05). CONCLUSIONS Asphyxia/anoxia, infection/inflammation, mechanical ventilation, anemia and hypoglycemia may increase the risk of brain injury in preterm infants.

Childs Nerv Syst 2019; 35:277-282. [PMID: 29978251 DOI: 10.1007/s00381-018-3872-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2018] [Accepted: 06/18/2018] [Indexed: 11/28/2022]
Abstract
PURPOSE The aim of this study was to assess the incidence and risk factors of intraventricular hemorrhage (IVH) as well as the role of cord blood erythropoietin (EPO) level in predicting the possibility of IVH in premature neonates. MATERIALS AND METHODS This prospective study included 140 preterm neonates born at hospitals affiliated to Shiraz University of Medical Sciences from May 2014 to April 2015. Complete blood count and cord blood EPO level was measured after birth. Brain ultrasonography was performed at 3 and 7-10 days after birth in these newborns. RESULTS Brain ultrasonography showed IVH in 8.57% (12/140) until the third day and 20% (28/140) at 7-10 days of life in premature neonates. Early gestational age, low birth weight, low Apgar score, and failure to give prenatal steroid were significant risk factors for developing IVH. The mean level of cord blood EPO was 20.95 ± 21.09 mIU/mL in premature newborns without IVH and 15.82 ± 17.11 mIU/mL with IVH. There was no correlation between the cord blood EPO and IVH in premature newborns. CONCLUSION Antenatal steroids therapy should be encouraged among women at risk of premature delivery. Our results showed that the cord blood EPO was not correlated with IVH in preterm neonates and further research is required to assess this relationship.
