RESUMO

Clitoromegaly can be congenital or acquired, and it is usually associated with exposure to androgen excess. Pathophysiological mechanisms responsible for transient clitoromegaly in premature female infants have not been fully elucidated. Herein, we present the case of an extremely premature female twin infant, with an extensive web of skin on the back of the left leg, hypoplastic left labia majora, and normal clitoris appearance at birth. At the age of 48 days, clitoral enlargement was observed. Significantly elevated levels of gonadotropins, testosterone, and dehydroepiandrosterone sulphate (DHEAS) were recorded. 17-hydroxyprogesterone (17OHP) was unremarkable, and anti-Müllerian hormone (AMH) was low, in accordance with normal female karyotype. Ovaries were not visualised ultrasonographically. During the following weeks, gradual normalisation of gonadotropin, testosterone, and DHEAS levels was accompanied by regression of clitoromegaly. As described in this case, transient clitoral enlargement may appear in extremely premature female infants due to transitory elevated androgens of ovarian and adrenal origin.

RESUMO

BACKGROUND: Necrotizing enterocolitis (NEC) is the most devastating gastrointestinal (GI) emergency in preterm neonates. Untargeted metabolomics may allow the identification of biomarkers involved in NEC pathophysiology. METHODS: We conducted a prospective study including preterm infants born at < 34 gestational weeks (GWs) whose urine was longitudinally collected at birth (< 48 h, T0) and at 14 (T1) and 28 days (T2). Neonates were followed for their development of NEC, spontaneous intestinal perforation (SIP), or other GI conditions and compared to those of matched healthy controls. Urine samples were investigated by untargeted metabolomic analysis based on mass-spectrometry. RESULTS: Thirty-five patients with NEC, 5 patients with SIP, 14 patients with other GI diseases and 113 controls were enrolled and selected for metabolomic analysis on the basis of their clinical characteristics and available samples. Considering urine samples at T0, the one-class classification approach was able to correctly classify 16/20 subjects (80%) who developed NEC, 3/3 (100%) who developed SIP and 5/7 subjects (71.4%) with other GI pathologies as not belonging to the control group. Neonates with surgical NEC had higher N-acetylaspartic acid, butyrylcarnitine and propionylcarnitine levels than did those with medical NEC. Considering the time evolution of the urinary metabolome, the NEC and control groups showed differences independently of the time point. CONCLUSIONS: The urinary metabolome is closely associated with the underlying GI disease from birth. Urinary metabolic features characterize NEC patients from healthy controls until 28 days of life. The early urinary metabolome has the potential to predict surgical NEC. Future studies are needed to validate our results.

RESUMO

Ambroxol, a commonly used mucolytic agent, has been extensively studied for its clinical effectiveness in managing respiratory conditions in pediatric and adult patients. The existing body of research on ambroxol demonstrates its safety and efficacy. However, its potential role in preventing and treating neonatal diseases still needs to be explored. This scoping review aims to shed light on the unexplored potential of ambroxol, particularly its applications in perinatal and neonatal care. We aim to offer valuable insights for healthcare professionals, researchers, and academics, thus presenting a positive perspective. Key scientific databases such as Google Scholar, PubMed, Cochrane Library, and Europe PMC were meticulously searched for relevant literature on ambroxol in perinatal and neonatal medicine. Gray literature was also surveyed, and the search encompassed all study designs and languages up to June 2024. Furthermore, citations and reference lists of relevant articles were scrutinized to identify additional pertinent literature. Ambroxol has demonstrated promising effects in preventing and managing respiratory distress syndrome (RDS). It can enter the placental circulation and rapidly build up in human lung tissue to a much greater extent than in plasma. It promotes fetal lung maturation, surfactant production, and alveolar expansion. Numerous studies have demonstrated the efficacy of antenatal and postnatal ambroxol in the prevention and treatment of RDS. Ambroxol has the potential to be administered intravenously or through nebulization, offering the hopeful possibility of reducing the high failure rate typically associated with non-invasive ventilation in extremely preterm infants, instilling a sense of hope and optimism about the potential of ambroxol. It also shows potential in treating bronchopulmonary dysplasia, meconium aspiration syndrome, and neonatal infections. Ambroxol has been observed to assist in the closure of patent ductus arteriosus in preterm infants by inhibiting vasodilator agents such as nitric oxide and exerting vasoconstrictive properties. However, these biological actions may raise concerns regarding the potential induction of pulmonary hypertension and an increased risk of necrotizing enterocolitis. The present scoping review also examines the clinical evidence and the potential of ambroxol in reducing the incidence of intraventricular hemorrhage in preterm infants. Ambroxol may have potential analgesic properties in managing neonatal pain, and as it can penetrate the blood-brain barrier, it suggests potential neuroprotective properties. These properties may encompass the modulation of microglial activation and the antagonistic impact on glutamate receptors. Ambroxol's attributes could contribute to a decreased susceptibility to neurological complications and have demonstrated anticonvulsant effects in preclinical studies. While low-to-moderate-quality evidence indicates potential applications of ambroxol in neonatal care, further research is needed to determine the drug's optimal dosing, timing, and safety profiles in this patient population. We need to investigate ambroxol's potential synergistic effects with antenatal steroids. Exploration is required to assess ambroxol's potential in reducing the high failure rate associated with non-invasive respiratory support for RDS. Lastly, comprehensive studies on the long-term neurodevelopmental outcomes of neonates exposed to ambroxol are essential.

RESUMO

BACKGROUND: Preterm birth is the leading cause of neonatal mortality accounting for 35% of all neonatal deaths worldwide, and the second most frequent cause of death for under five children. Despite different efforts, preterm neonatal mortality is still persistently high in Ethiopia. Little is known about death and its predictors among preterm neonates in the study area. OBJECTIVE: This study is aimed at estimating the incidence of mortality and its predictors among preterm neonates admitted to the NICU of NEMMCSH. METHODS AND MATERIALS: A hospital-based prospective follow-up study was conducted from January to November 2022. A total of 197 preterm neonates were selected consecutively and followed. The Kaplan-Meier survival and failure curves were used to describe the proportion of deaths over time and to compare groups. The independent effects of covariates on the hazard of death were analyzed using a multivariable Cox proportional hazard model. RESULTS: Preterm neonates were followed for 1840 person-days. The mean time to death was 5.68 days (SD = 5.54). The incidence of mortality was 26.08 (95% CI: 19.65, 34.61) per 1000 person days. Preterm neonates of mothers with eclamsia (AHR = 3.03), preterm neonates who have not received KMC (AHR = 2.26), and preterm neonates who have not exclusively breastfed (AHR = 4.4) had higher hazards of death as compared to their counterparts. CONCLUSION AND RECOMMENDATION: The mean time to death was 5.68 days (SD = 5.54). The incidence of mortality was 26.08 per 1000 person days. Eclamsia, KMC, and exclusive breastfeeding were significant predictors of death among preterm neonates. The role of KMC in reducing mortality rates and improving outcomes has to be emphasized for mothers and families. Caregivers have to ensure that mothers and families receive adequate support and resources to facilitate KMC, including access to lactation support, counseling, and assistance with practical aspects of caregiving. Counseling and practical support to enhance exclusive breastfeeding initiation and continuation have to be strengthened. Special attention has to be given to the preterm neonates of mothers with eclampsia.

RESUMO

Microbiota plays a crucial role in intestinal maturation in preterm newborns. The clinical manifestation of the immaturity of the gastro-intestinal tract is called feeding intolerance (FI). This condition may resolve spontaneously or dramatically evolve into necrotizing enterocolitis. One of the most challenging tasks for the neonatologist is to identify those neonates that will develop the disease early in order to adequately provide nutrition to these patients, from the very first hours of life. A close interplay between the maturity of the gastro-intestinal tract and gut microbiota has been described; however, in preterm neonates, this relationship is still undefined. We analyzed the bacterial composition of stool samples, collected early in life, from 30 preterm newborns classified as intolerant or tolerant according to the degree of readiness of the gastro-intestinal tract to receive enteral nutrition. The Pielou evenness index was significantly increased in intolerant compared with tolerant newborns. Data corrected for confounding variables confirmed that the occurrence of gut maturation was independently influenced by Pielou evenness at birth. A lower bacterial diversity very early in life is associated with improved feeding tolerance in preterm newborns. The abundance analysis showed that neonates not ready to receive enteral nutrition for feeding intolerance show, after birth, an increased abundance of Proteobacteria, Lachnospiracae, Enterobacter and Acinetobacter. We can argue that those are the taxa that prevent the establishment of pioneer bacteria. A lower alpha-diversity, in the first days of life, may facilitate the seeding of beneficial pioneer bacteria that, in turn, drive healthy microbial colonization during neonatal life.

RESUMO

An indirect inguinal hernia is a commonly seen congenital condition that can impact infants within their first year of life. An inguinal hernia arises when a portion of the intestines, omentum, or reproductive structures herniate into the scrotal sac or labia through the patent processus vaginalis. These hernias occur more frequently in preterm newborns. The contents of a hernia often consist of the small bowel, colon, omentum, and either the ovary or testicle. The occurrence of a uterus in a herniated sac is uncommon. The presence of a uterus, ovary, and fallopian tube is exceptionally rare, with only a few cases reported in the literature. We present a unique case of a 10-day-old female neonate who was delivered at 37 weeks of gestation and brought to the Paediatric Outpatient Department with swelling in the left inguinal region that had been present for the past five days. During the clinical examination, an irreducible mass was found in the left inguinal region. The ultrasound scan showed the uterus, ovary, fallopian tube, and minimal free fluid in the herniated sac. Colour Doppler evaluation of the uterus and ovaries revealed good vascularity. A diagnosis of a left inguinal hernia containing the uterus, left ovary, and fallopian tube, with no signs of ovarian torsion, was established. We performed a surgical procedure in which the likelihood of adhesions was taken into consideration, and the organs were removed from the hernial sac. We conducted the reintegration of the organs back into the pelvis, ligation of the high sac, and further repair of the internal inguinal ring to prevent the recurrence of the hernia. The surgical procedure was successful, and the postoperative period was without any complications. After the surgery, the patient was advised to have clinical and radiological follow-up for a period of one year. We recommend that a high-resolution ultrasound (HRUS) scan be routinely performed in neonates with an asymptomatic or symptomatic palpable mass in the inguinal region for early diagnosis and characterization of the herniated structures, as well as to assess their viability.

RESUMO

Introduction: The high neonatal mortality rate in low- and middle-income countries (LMICs) such as Nigeria has lasted for more than 30 years to date with associated nursing fatigue. Despite prominent hard work, technological improvements, and many publications released from the country since 1990, the problem has persisted, perhaps due to a lack of intervention scale-up. Could there be neglected discoveries unwittingly abandoned by Nigerian policymakers over the years, perhaps locked up in previous publications? A careful review may reveal these insights to alert policymakers, inspire researchers, and refocus in-country research efforts towards impactful directions for improving neonatal survival rates. The focus was to determine the prevailed effectiveness of LMIC medical academia in creating solutions to end the high neonatal mortality rate. Methods: An unconventional systematic review protocol structure following the PRISMA 2020 checklist was designed and registered at INPLASY (registration number: INPLASY202380096, doi: 10.37766/inplasy2023.8.0096). A jury of paediatricians was assembled and observed by a team of legal professionals. The jury searched the literature from 1990 to the end of 2022, extracted newborn-related articles about Nigeria, and assessed and debated them against expected criteria for solution creation, translation, scale-up, sustainability, and national coverage. Each juror used preset criteria to produce a verdict on the possibility of a published novel idea being a potential game-changer for improving the survival rate of Nigerian neonates. Results: A summation of the results showed that 19 out of 4,286 publications were assessed to possess potential strategies or interventions to reduce neonatal mortality. Fourteen were fully developed but not appropriately scaled up across the country, hence denying neonates proper access to these interventions. Conclusion: Nigeria may already have the required game-changing ideas to strategically scale up across the nation to accelerate neonatal survival. Therefore, LMIC healthcare systems may have to look inward to strengthen what they already possess. Systematic Review Registration: https://inplasy.com/, identifier (INPLASY202380096).

RESUMO

Postoperative acute kidney injury (AKI) is a common complication that is associated with chronic kidney disease, early postsurgical mortality, and prolonged hospital stays. Preterm neonates who undergo surgery are at risk factors for AKI due to underdeveloped kidneys. To date, little is known about the incidence and perioperative risk factors for AKI in preterm neonates undergoing noncardiac surgery. Preterm neonates who underwent noncardiac surgery between January May 1, 2020, and February 28, 2023, were enrolled in the trial according to the inclusion criteria. Both multivariable and logistic regression analyses were used to analyze the associations between characteristic data and AKI. In total, 106 preterm neonates met the inclusion criteria, and 25 preterm neonates (23.6%) developed postoperative AKI. Multivariate analysis revealed that the factors associated with AKI were gestational age < 32 weeks [OR: 4.88; 95% CI (1.23-19.42)], preoperative sepsis [OR: 3.98; 95% CI (1.29-12.28)], and intraoperative hypotension [OR: 3.75; 95% CI (1.26-11.15)]. Preterm neonates who developed AKI were more likely to have longer hospital length of stays (38 [18,69] days vs. 21[12,46]) and higher medical costs (93,181.6 [620450.0,173,219.0] ï¿¥ vs. 58,134.6 [31015.1,97,224,1) ï¿¥ than neonates who did not develop AKI. Preterm neonates who underwent noncardiac surgery had a high incidence of AKI. Independent risk factors for AKI in preterm neonates who underwent noncardiac surgery were low gestational age, preoperative sepsis, and intraoperative hypotension. Preterm neonates who developed AKI were more likely to have longer hospital stays and higher medical costs.

RESUMO

Umbilical venous catheterization is a common procedure in the neonatal care unit. Although it is an easy procedure, insertion under suboptimal techniques may have devastating effects on the newborn. We present a rare case of umbilical venous catheter (UVC) malposition complicated with respiratory distress, pleural effusion, and acute kidney injury.

RESUMO

Introduction Hypoglycemia is a critical concern in neonatal care, particularly among preterm infants. This study aims to investigate the frequency of hypoglycemia within the first 24 hours of life in preterm neonates, considering factors such as gestational age (GA), birth weight, and gender. Materials and methods A cross-sectional study was conducted from February to August 2021. The sample comprised 186 preterm infants selected through consecutive sampling. Data collection involved demographic information, glucose level monitoring, and symptom assessment. Results Of the 186 preterm neonates, 31.7% (n=59) experienced hypoglycemia within the first 24 hours, with feeding refusal being the predominant symptom. There was a significant difference in hypoglycemia occurrence between infants born before and after 32 weeks of gestation (p<0.05). Males were slightly more affected than females, although not statistically significant. Infants weighing less than 2 kg showed a higher susceptibility to hypoglycemia. Conclusion The early detection and management of hypoglycemia are crucial in preterm neonatal care. Close monitoring, especially in the initial four hours, is essential to prevent complications. Larger studies are warranted to confirm these findings and improve understanding and management strategies for hypoglycemia in preterm neonates, particularly within the first 24 hours of life.

RESUMO

BACKGROUND: Imperforate hymen is the most common congenital defect of the female urogenital tract. The spectrum of clinical manifestations is broad, ranging from mild cases undiagnosed until adolescence to severe cases of giant intraabdominal masses. The most common complication of hydrocolpos is bladder compression, resulting in obstructive uropathy and hydronephrosis. CASE PRESENTATION: We present here the case of a preterm neonate who was admitted to the surgical neonatal intensive care unit for bowel obstruction. The baby did not appear septic or unwell, a small amount of meconium passed frequently, and no bilious gastric residuals occurred. Based on these findings, acute abdominal obstruction was doubtful, and the surgeon chose a conservative (watch and wait) approach. Subsequently, we performed abdominal ultrasound and magnetic resonance imaging based on unclear information about a suspicious abdominal mass raised by the gynecologist shortly before the emergency C-section. The final diagnosis was congenital hydrocolpos due to imperforate hymen. The pediatric gynecologist indicated an incision of the imperforate hymen under general anesthesia. The incision resolved abdominal distention as well as the bowel obstruction. CONCLUSION: The presentation of hydrocolpos was not typical (no bulging in the vaginal introitus) in our case, and clinical symptoms implied acute bowel obstruction shortly after birth. The surgeon chose a conservative (watch and wait) approach as the baby did not appear unwell on the second day of life. Fortunately, diagnostic laparotomy was not required as the next step in bowel obstruction management. All clinical symptoms resolved after a minor surgical procedure.

RESUMO

Neonatal brain injury (NBI) is a critical condition for preterm neonates with potential long-term adverse neurodevelopmental outcomes. This prospective longitudinal case-control study aimed at investigating the levels and prognostic value of serum neuron-specific enolase (NSE) during the first 3 days of life in preterm neonates (<34 weeks) that later developed brain injury in the form of either periventricular leukomalacia (PVL) or intraventricular hemorrhage (IVH) during their hospitalization. Participants were recruited from one neonatal intensive care unit, and on the basis of birth weight and gestational age, we matched each case (n = 29) with a neonate who had a normal head ultrasound scan (n = 29). We report that serum NSE levels during the first three days of life do not differ significantly between control and preterm neonates with NBI. Nevertheless, subgroup analysis revealed that neonates with IVH had significantly higher concentrations of serum NSE in comparison to controls and neonates with PVL on the third day of life (p = 0.014 and p = 0.033, respectively). The same pattern on the levels of NSE on the third day of life was also observed between (a) neonates with IVH and all other neonates (PVL and control; p = 0.003), (b) neonates with II-IV degree IVH and all other neonates (p = 0.003), and (c) between control and the five (n = 5) neonates that died from the case group (p = 0.023). We conclude that NSE could be an effective and useful biomarker on the third day of life for the identification of preterm neonates at high risk of developing severe forms of IVH.

RESUMO

Background Bronchopulmonary dysplasia (BPD) is a significant complication in extremely preterm infants. Therefore, early diagnosis of BPD is important for planning treatment strategies. In this study, we aimed to assess the predictive efficacy of the Respiratory Severity Score (RSS) in determining severe BPD or death outcomes in very preterm infants. Methodology This retrospective study included preterm infants born with a gestational age of ≤30 weeks. The inclusion criteria comprised individuals who were mechanically ventilated (<1 week) during the first four weeks of life. Any patients who died during the first seven days of life were excluded. RSS values were recorded on days 3, 14, 21, and 28 of life. Multivariate logistic regression was used to identify a correlation between RSS and patient outcomes. Results A total of 154 infants were included in the analysis, of whom 82 (53.24%) developed severe BPD and 38 (24.67%) died. RSS was higher in patients who either died or developed severe BPD compared to those who survived. The multivariate logistic regression analysis revealed that RSSs at postnatal day 14 (odds ratio (OR) = 3.970; 95% confidence interval (CI) = 1.114-14.147; p < 0.05), day 21 (OR = 6.201; 95% CI = 1.937-19.851; p < 0.05), and day 28 (OR = 8.925; 95% CI = 3.331-28.383; p < 0.05) was significantly associated with a higher risk of death or severe BPD. Conclusions The findings of the present study revealed that RSS can help predict the risk of severe BPD in very preterm infants.

RESUMO

BACKGROUND: To find the obstetrical and delivery associated risk factors of antenatal and postnatal grade III intraventricular hemorrhage (IVH) or periventricular hemorrhagic infarction (PVHI) in preterm neonates. METHODS: A retrospective study of obstetric and delivery associated risk factors included neonates (<35 gestational weeks) with severe IVH/PVHI (n = 120) and a prospectively collected control group (n = 50). The children were divided into: (1) antenatal onset group (n = 27) with insult visible on cerebral ultrasonography within the first 12 hours of birth or periventricular cystic changes visible in PVHI within the first 3 days; (2) neonatal onset group (n = 70) with insult diagnosed after initial normal findings or I-II grade IVH, and (3) unknown time-onset group (n = 23) with insult visible at > 12 h of age. RESULTS: The mothers of the antenatal onset group had significantly more bacterial infections before delivery compared to the neonatal onset group: 20/27 (74.1%) versus 23/69 (33.3%), (odds ratio (OR) 5.7 [95% confidence interval 2.1-16]; p = 0.0008) or compared to the control group (11/50 (22%); OR 11 [2.8-42]; p = 0.0005). Placental histology revealed chorioamnionitis more often in the antenatal compared to the neonatal onset group (14/21 (66.7%) versus 16/42 (38.1%), respectively; OR 3.7 [1.18-11]; p = 0.025). Neonates with neonatal development of severe IVH/PVHI had significantly more complications during delivery or intensive care. CONCLUSIONS: Bacterial infection during pregnancy is an important risk factor for development of antenatal onset severe IVH or PVHI. In neonates born to mothers with severe bacterial infection during pregnancy, cerebral ultrasonography is indicated for early detection of severe IVH or PVHI.

RESUMO

OBJECTIVES: Critical hyperbilirubinemia in preterm neonates, a condition requiring greater attention, is treated with phototherapy or exchange transfusion when bilirubin results exceed gestational age and age-specific medical decision levels (MDLs) to prevent bilirubin-induced neurologic damage. Conventional evaluation involves multiple manual steps and is poised to inconsistencies and delays. METHODS: We designed and implemented an electronic clinical decision support (CDS) tool to identify and alert neonatal intensive care unit clinicians of critical hyperbilirubinemia with a SmartZone alert. We evaluated the performance of our manual evaluation workflow, the accuracy of the electronic CDS tool, and the outcome of the electronic CDS tool to reduce the time to place orders for interventions. RESULTS: Among the 22 patients who met the criteria to have phototherapy ordered before implementing the electronic CDS tool, 20 (90%) had phototherapy ordered. Fourteen (70%) phototherapy orders were placed less than 24 hours, 4 phototherapy orders were placed 24 to 72 hours, and 2 orders were placed more than 72 hours after bilirubin results exceeded the corresponding MDLs. Among the 15 patients who met the criteria to have phototherapy ordered after implementing the electronic CDS tool, all (100%) received phototherapy orders, with 14 (93%) placed less than 24 hours and 1 order placed less than 48 hours. The electronic CDS tool identified all eligible patients correctly. The proportion of phototherapy ordered less than 24 hours increased from 70% to 93% after the implementation of the electronic CDS tool. CONCLUSIONS: The electronic CDS tool promoted more appropriate and timely intervention orders to manage critical hyperbilirubinemia in preterm neonates.

RESUMO

BACKGROUND: Neonatal serum creatinine (n-sCr) concentrations during the first few days of life have been reported to correlate with the maternal serum Cr (m-sCr) concentrations. We aimed to derive a regression equation to describe the relationship between n-sCr within 24 h of birth in preterm neonates and m-sCr before delivery, and to perform multiple regression analysis to identify factors related to n-sCr and the difference between n-sCr and m-sCr. METHODS: We recruited preterm neonates who were treated at the University of the Ryukyus Hospital between March 2012 and October 2022. Patients with underlying diseases or conditions that might affect hemodynamics were excluded, as were patients whose n-sCr and m-sCr were not measured in pairs. A total of 278 cases were included in the analysis. RESULTS: The median (interquartile range) gestational age, birth weight, n-sCr, and m-sCr were 33.9 weeks (32.0-35.1 weeks), 1901 g (1579-2284 g), 0.55 mg/dL (0.48-0.64 mg/dL), and 0.47 mg/dL (0.42-0.57 mg/dL), respectively. The regression equation derived was n-sCr = 0.092 + 0.970 × m-sCr (R2 = 0.768, p < 0.001). The multiple regression analysis showed that m-sCr was the most potent influencer of n-sCr, and the ratio of placental weight to birth weight (PW/BW ratio) was the most potent influencer of the difference between n-sCr and m-sCr. CONCLUSIONS: We have obtained an approximate equation of n-sCr = 0.1 + m-sCr for preterm neonates. In addition, the high PW/BW ration may reduce the difference between n-sCr and m-sCr.

RESUMO

Intraventricular hemorrhage (IVH) is a type of bleeding that occurs through the germinal matrix and comes through the ependymal cells into the ventricular cavity. It is mostly seen in preterm neonates but can also be seen sometimes in term neonates. Various factors predispose to preterm delivery; it can be spontaneous or medically induced. Spontaneous IVH occurs in cases of intrauterine infections in the mother, and it can be induced in cases of medical emergencies such as preeclampsia and eclampsia. The brain of a preterm newborn is not fully developed as it does not have pericytes and proteins, so it can bleed very quickly, which can cause IVH. Also, the vessels supplying the germinal matrix are immature and highly vascularized. IVH has four grades based on findings detected on cranial ultrasound and MRI. Management includes medical and surgical management; medical management includes phenobarbitone used for seizures and prophylaxis. Surgical management includes drainage, irrigation, and fibrinolytic therapy (DRIFT), and neuro-endoscopic lavage. IVH causes various short-term and long-term neurodevelopmental consequences. Long-term complications include cerebral palsy and intellectual disability, which hamper the life of the child. It mainly presents with seizures, flaccidity, decerebrate posture, etc. Various preventive measures can be taken to tackle IVH in newborns. First of all, preterm delivery should be avoided, and intrauterine infections in mothers should be treated. The administration of corticosteroids should be done for all preterm deliveries as it helps in the maturation of organs. The administration of magnesium sulfate should be done as it is neuroprotective and reduces cerebral palsy in the future. Delayed cord clamping is to be done to reduce recurrent blood transfusions and decrease the risk of IVH. This article explains the pathogenesis, management, prevention, and future outcomes of IVH.

RESUMO

Neonates with absent-or-reversed umbilical artery end-diastolic flow (AREDF) are at an increased risk of feeding problems. In this retrospective study, authors evaluated the incidence of feed intolerance in 213 preterm neonates (January 2017-May 2022) with AREDF. The median (IQR) gestation and birth weight were 32 (30, 33) wk and 1120 (840, 1425) g, respectively. Of 213 neonates, 103 (48.4%; 95% CI 41.5%, 55.3%) neonates developed feed intolerance. Twelve of 213 neonates developed any stage necrotizing enterocolitis (NEC) (5.6%; 95% CI 2.9%, 9.6%) at a median age of 10 d. On multivariate regression, gestation was the only independent predictor of feed intolerance (OR 1.48; 95% CI 1.28, 1.70; for every 1 wk decrease below 36 wk). Almost 50% of preterm neonates with AREDF develop feed intolerance. Alternative feeding strategies warrant exploration to optimise nutrition in these neonates.

RESUMO

BACKGROUND: Hypoglycemia in neonates is common and contributes to 4.0-5.8% of neonatal intensive care unit (NICU) admissions. In utero nicotine exposure is underexplored as a potential contributor to neonatal hypoglycemia. Rat models have shown that in utero nicotine exposure can be associated with a reduction in pancreatic beta cell mass, leading to glucose dysregulation. The primary aim of this work is to study the risk of developing hypoglycemia after birth in a population of in utero nicotine-exposed neonates. METHODS: We conducted a retrospective matched cohort study that augmented an existing dataset of neonates admitted to a level IV NICU with household-based in utero nicotine exposure (N = 335). Neonates in the control group parents denied household smoking (N = 325), were born within a 6-month timeframe, and were within a birthweight of 50 grams of a nicotine-exposed neonate. Data reviewed included gestational age, growth parameters, maternal history of diabetes, and glucose levels within the first three hours of life per unit protocol. RESULTS: 660 neonates were included in the analysis. In utero nicotine exposure demonstrated a 94.3% posterior probability (PP) for greater hypoglycemia risk (RR = 1.185, 95% CrI = [0.953, 1.445]). A 94.6% PP was demonstrated when neonates who were small for gestational age, intrauterine growth-restricted, and born to diabetic mothers were excluded (n = 482; RR = 1.271, 95% CrI = [0.946, 1.669]). CONCLUSION: Nicotine exposure in utero was found to be a potential risk factor for developing hypoglycemia after birth. Mechanisms of action should be explored, and additional research on in utero nicotine exposure risks should follow.

RESUMO

AIM: Preterm children are highly vulnerable to sensorial impairments through Retinopathy Of Prematurity (ROP). The objective was to determine whether some cases of ROP requiring surgery could be secondary to deficiencies in care pathways. METHODS: Descriptive study of neonatal characteristics and the screening/treatment pathways of children treated for stage ≥4A ROP from 2009 to 2020 in a referral unit in France. RESULTS: Twenty-five preterm children (44 eyes) were included: median gestational age was 25 weeks, and median birthweight was 700 grams. Eighty-four per cent had received at least one fundus examination, 50% of which were completed on time. At the time of retinal detachment diagnosis, only 36% of the children had received laser or anti-vascular endothelial growth factor (VEGF) intra-vitreal injection. ROP stage was only reported in 8%, and the zone or type was reported in 16% of the files. CONCLUSION: The risk of blindness and the effectiveness of laser or anti-VEGF treatment highlight the need to enhance screening and treatment practices in France.
