RESUMEN

OBJECTIVE: Magnesium sulfate (MgSO4) provides effective fetal neuroprotection. However, there is conflicting evidence regarding the association between antenatal MgSO4 exposure and patent ductus arteriosus (PDA). Thus, herein, we aimed to evaluate the association between antenatal MgSO4 exposure and PDA. STUDY DESIGN: Preterm infants born between 240/7 and 316/7 weeks of gestation were included in this retrospective study. Infants who died within the first 72 hours of life and those with significant congenital anomalies were excluded from the study. Echocardiographic and clinical assessment parameters were used to define PDA and hemodynamically significant PDA (hsPDA). Treatments were planned according to the standard protocols of the unit. The following data were collected from hospital medical records: perinatal characteristics, neonatal outcomes, detailed PDA follow-up findings, and maternal characteristics including MgSO4 exposure and doses. RESULTS: Of the 300 included infants, 98 (32.6%) were exposed to antenatal MgSO4. hsPDA rates were similar in the infants exposed and not exposed to antenatal MgSO4, when adjusted for antenatal steroid administration, gestational age, and birth weight (OR: 1.6, 95% CI: 0.849-3.118, p = 0.146). The rates of PDA ligation and open PDA at discharge were similar between the groups. A cumulative MgSO4 dose of >20 g was associated with an increased risk of hsPDA (crude OR: 2.476, 95% CI: 0.893-6.864, p = 0.076; adjusted OR: 3.829, 95% CI: 1.068-13.728, p = 0.039). However, the cumulative dose had no effect on the rates of PDA ligation or open PDA at discharge. Rates of prematurity-related morbidities and mortality were similar between the groups. CONCLUSION: Although antenatal MgSO4 exposure may increase the incidence of hsPDA, it may not affect the rates of PDA ligation or open PDA at discharge. Further studies are required to better evaluate the dose-dependent outcomes and identify the MgSO4 dose that not only provides neuroprotection but also has the lowest risk of adverse effects. KEY POINTS: · Antenatal exposure of MgSO4 may cause PDA.. · Antenatal MgSO4 exposure may not increase the rates of PDA ligation or open PDA at discharge.. · Further studies are required to better evaluate the dose-dependent outcomes and optimal MgSO4 dose..

RESUMEN

INTRODUCTION: We aimed to evaluate the use of "Neonatal Sequential Organ Failure Assessment" (nSOFA) scoring in predicting mortality, to compare the accuracy of nSOFA scores at different time points in very preterm infants with late-onset sepsis (LOS), and to investigate other possible parameters that would improve the prediction. METHODS: This single-center, retrospective study included preterm infants born atS<32 weeks' gestation with culture-proven LOS. The nSOFA scores of non-fatal and fatal episodes were compared at nine time points. RESULTS: Of 120 culture-proven LOS episodes in 106 infants, 90 (75%) episodes were non-fatal and 30 (25%) episodes were fatal. The mean birth weight (BW) of the infants who died was lower than that of survivors (p=0.038). In the fatal LOS episodes, median nSOFA scores were higher at all time points measured before sepsis evaluation, at the time of evaluation, and at all time points measured after the evaluation (p<0.001). nSOFA scores before death and at 48 hours were higher in the fatal episodes (p<0.001). At the time of sepsis assessment, nSOFA score>4 was associated with a 7- to 16-fold increased risk of mortality. Adjustment for BW, lymphocyte and monocyte counts increased the risk to 9- to 18-fold. CONCLUSION: This study demonstrated that the use of nSOFA to predict mortality and morbidity in extremely preterm infants seems feasible. The scoring system could be improved by evaluating the other parameters.

RESUMEN

Continuous kidney replacement therapy (CKRT) use has increased in recent years, but anticoagulation is a challenge for neonates. Regional citrate anticoagulation (RCA) is rarely preferred in neonates because of citrate accumulation (CA) and metabolic complications. We aimed to demonstrate the efficacy and safety of RCA in neonates. We retrospectively analyzed the medical records of 11 neonates treated with RCA-CKRT between 2018 and 2023. The initial dose of RCA was 2.1-3 mmol/l, and then, its dose was increased according to the level of ionized calcium (iCa+2) in the circuit and patients. The total/iCa+2 ratio after-treatment > 2.5 was indicated as CA. We evaluated to citrate dose, CA, circuit lifespan, and dialysis effectivity. The median gestational age was 39 (36.4-41.5) weeks, the median body weight (BW) was 3200 (2400-4000) grams, and the mean postnatal age was 4 (2-24) days. The most common indication for CKRT was hyperammonemia (73%). All neonates had metabolic acidosis and hypocalcemia during CKRT. Other common metabolic complications were hypophosphatemia (90%), hypokalemia (81%), and hypomagnesemia (63%). High dialysate rates with a median of 5765 ml/h/1.73 m2 allowed for a rapid decrease in ammonia levels to normal. Four patients (36.3%) had CA, and seven (63.7%) did not (non-citrate accumulation, NCA). Mean BW, median postnatal age, biochemical parameters, coagulation tests, and ammonia levels were similar between the CA and NCA groups. Low pH, low HCO3, high lactate, and SNAPPE-II scores could be associated with a higher T/iCa ratio. CONCLUSION:  RCA was an efficient and safe anticoagulation for neonates requiring CKRT. Metabolic complications may occur, but they could be managed with adequate supplementation. WHAT IS KNOWN: • Continuous kidney replacement therapy (CKRT) has become popular in recent years due to its successful treatment of fluid overload, electrolyte imbalance, metabolic acidosis, multi-organ failure, and hyperleucinemia/hyperammonemia associated with inborn errors of metabolism. • The need for anticoagulation is the major difficulty in neonatal CKRT. In adult and pediatric patients, regional citrate anticoagulation has been shown to be effective. WHAT IS NEW: • RCA is an effective and safe anticoagulation method for neonates who require CKRT. • Electrolyte imbalances and metabolic acidosis could be managed with adequate supplementation and appropriate treatment parameters such as citrate dose, blood flow rate, and dialysate flow rate.

RESUMEN

We aimed to compare the definitions of National Institute of Child Health and Human Development (NICHD) for bronchopulmonary dysplasia (BPD) for determining the incidences, and predicting late death and respiratory outcome. This retrospective cohort study included infants born at<32 weeks' gestation who survived up to 36 weeks' postmenstrual age (PMA). Infants were classified as having BPD or no BPD per thedefinitions of NICHD 2001 and 2018. The incidences of BPD were 49 and 32% according to the 2001 and 2018 NICHD definitions. Gestational age, birth weight and intubation after birth were associated with BPD by both definitions. The NICHD 2018 definition displayed similar sensitivity (100%) and negative predictive value (100%), and higher specificity (70 vs. 52%) for predicting death after 36 weeks' PMA; a higher specificity (72 vs. 53%), comparable negative predictive value (77 vs.76%), but lower sensitivity for predicting adverse respiratory outcome within 12 months corrected age compared with the NICHD 2001 definition. The NICHD 2018 definition is as powerful as the 2001 definition for predicting late death and seems to be a better indicator for long-term respiratory outcome. The use of supplemental oxygen or oxygen plus respiratory support should be considered while predicting both late death and long-term respiratory outcome.

RESUMEN

INTRODUCTION: Neonatal appendicitis is a very rare surgical entity. Non-specific symptoms such as feeding intolerance, abdominal distension, vomiting, increased gastric residue, lethargy, and fever may be present. The majority of reported cases could not be identified early. In this report, we present an extremely low-birth-weight preterm neonate who has been diagnosed with appendicitis. CASE PRESENTATION: A 980-gram preterm baby girl was born at 31 1/7 weeks of gestation. The physical examination was normal at birth. Her initial clinical course was uneventful. On the 7th day of life, she developed abdominal distention and tenderness. She had an episode of bloody stools and bilious vomiting. An abdominal X-ray suggested localized perforation in the cecum with an air-fluid level in the right lower quadrant. The clinical findings suggested necrotizing enterocolitis and perforation, and a diagnostic laparotomy was performed. The bowel was found to be normal with a necrotic appendix. The appendectomy was performed. She was discharged from the neonatal intensive care unit with no complications. CONCLUSION: Appendicitis is extremely rare in the neonatal period. It is quite challenging to evaluate the presentation accurately, which causes a delay in diagnosis. However, if an atypical NEC or peritonitis is present, appendicitis should be considered. Early diagnosis and timely surgical intervention improve the prognosis of neonatal appendicitis.

RESUMEN

BACKGROUND: We aimed to assess symptoms, laboratory findings, and radiological abnormalities in patients diagnosed with inherited metabolic disorders (IMDs) in the neonatal intensive care unit. METHODS: A total of 6,150 newborns treated in a third-level neonatal intensive care unit between 2012 and 2020 in Turkey were screened, of which 195 consulted with a suspicion of metabolic disease based on their clinical, laboratory, or radiological findings were included in the present study. RESULTS: The prevalence of IMDs in the patients was 1:94.6. Those consulted in the department of pediatric metabolism were divided into two groups, with the 65 diagnosed with IMDs assigned as Group I, and the 130 patients who were not diagnosed with IMDs as Group II. The most common IMDs were organic acidemias (29.23%) and urea cycle disorders (UCDs) (26.15%). The rates of consanguinity marriage (75.3% vs 37.6%, P < 0.001), siblings diagnosed with an IMD (27.6% vs 3.8%, P < 0.001), and sibling death (56.9% vs 14.6%, P < 0.001) were higher in Group I than in Group II. Hyperammonemia (61.5% vs 18.4%, P < 0.001) was the most common laboratory finding in Group I, and anemia (Group I 60.0% vs 43.0% P = 0.033), metabolic acidosis (53.8% vs 36.9%, P = 0.028) and respiratory alkalosis (16.9% vs 1.5%, P < 0.001) were all higher in Group I. CONCLUSIONS: This retrospective study found that the results of clinical findings and basic laboratory tests could be strong indicators of IMDs, although extensive newborn screening tests and advanced biochemical and genetic tests should be carried out for the diagnosis of IMDs in newborns.

RESUMEN

Background/aim: Continuous renal replacement therapy (CRRT) has significant benefits in the treatment of critically ill children. The objective of this study is to describe the treatment indications, methods, demographics, and outcome of the patients who received CRRT in our pediatric intensive care unit and neonatal care unit, and, according to these results, we also aim to make improvements in our unit-based interventions. Material and methods: In this single-centered study, we retrospectively evaluated medical charts of the patients admitted to our intensive care units and received CRRT between February 2010 and November 2015. Results: Fifty of 60 patients were included in this study. Newborns made up 28% (n = 14) of the patients. The mean body weight was 18.4 kg (2.3-98 kg). CRRT indications were fluid overload (30%), acute kidney injury (40%), metabolic disease (24%), electrolyte impairment (4%), and drug intoxication (2%). The most common method of CRRT was continuous venovenous hemodiafiltration (CVVHDF) (72%). The mean duration of CRRT was 135 hours (1-864) and totally 143 filters, polyarylethersulfon (n = 23.46%) and polyacrylonitrile (n = 27.54%) were used. Overall survival was 42%. The survival rate of newborns was significantly higher (P = 0.046). Conclusion: CRRT is a lifesaving method that can be applied to critically ill children with acute kidney injury and fluid overload at any age and weight by experienced teams.

RESUMEN

Background/aim: Most inborn metabolic diseases are diagnosed during the neonatal period. The accumulation of toxic metabolites may cause acute metabolic crisis with long-term neurological dysfunction and death. Renal replacement therapy (RRT) modalities allow the efficient removal of toxic metabolites. In this study, we reviewed our experience with continuous venovenous hemodiafiltration (CVVHDF) as RRT for newborns with an inborn metabolic disease. Materials and methods: Patients diagnosed with an inborn metabolic disease and who received CVVHDF treatment at our neonatal intensive care unit between January 2014 and December 2017 were included in this study. Their demographic and clinical data were collected, and the efficacy and safety of CVVHDF was evaluated. Results: A total of nine continuous RRT (CRRT) sessions as CVVHDF were performed in eight newborns with a diagnosis of urea cycle defect (n = 5), maple syrup urine disease (n = 2), or methylmalonic acidemia (n = 1). The mean age at admission was 10 ± 8.6 days (range: 3­28 days). The mean plasma levels of ammonium were 1120 ± 512.6 mg/dL and 227.5 ± 141.6 mg/dL before and at the end of the treatment, respectively. Plasma levels of leucine were 2053.5 ± 1282 µmol/L and 473.5 ± 7.8 µmol/L before and at the end of the treatment, respectively. The CVVHDF duration was 32.3 ± 11.1 h (median: 37 h; range: 16­44 h), and the mean length of hospitalization was 14.6 ± 12.9 days. The mean duration of CVVHDF was 32.3 ± 11.1 h (range: 16­44 h). Circuit clotting was the most common observed complication (37.5%) and the survival rate was 50%. Among surviving patients, two developed severe and two developed mild mental and motor retardation. Conclusion: CVVHDF is a CRRT modality that can be used to treat newborns with an inborn metabolic disease. Early diagnosis, commencement of specific medical therapy, diet, and extracorporeal support, if needed, are likely to result in improved short and long- term outcomes.

RESUMEN

OBJECTIVE: This study aims to evaluate the effect of the prophylactic continuous positive airway pressure (CPAP) administration in the delivery room to newborns who were delivered by elective cesarean section (CS). STUDY DESIGN: Inborn infants with gestational age between 34(0/7) to 38(6/7) and born by elective CS were prospectively randomized to receive either prophylactic CPAP for 20 minutes via face mask or standardized care without CPAP in the delivery room. Primary outcomes were the incidence of transient tachypnea of the newborn (TTN) and neonatal intensive care unit (NICU) admission due to respiratory distress. RESULTS: A total of 259 infants with a mean gestational age of 37.7 ± 0.8 weeks and birth weight of 3,244 ± 477 g were included. A total of 134 infants received prophylactic CPAP and 125 received control standard care. The rate of NICU admission was significantly lower in prophylactic CPAP group (p = 0.045). Although the rate of TTN was lower in the prophylactic CPAP group, the difference was not statistically significant (p = 0.059). The rate of NICU admission due to respiratory distress was significantly higher in late-preterm cohort than early-term cohort (p < 0.0001). CONCLUSION: Prophylactic CPAP administration decreases the rate of NICU admission without any side effect in late-preterm and early-term infants delivered by elective CS.

RESUMEN

BACKGROUND: Soluble urokinase plasminogen activator receptor (suPAR) has been studied in a variety of diseases. The aim of the study is to investigate the levels of suPAR in neonates with sepsis. METHODS: The infants enrolled to this prospective study were classified into four groups. Group 1, 2, and 3 were referred as the patient groups (40 infants), and group 4 was referred as control group (26 infants). Blood samples for whole blood count, C-reactive protein (CRP), suPAR and blood culture were obtained before initiating antimicrobial therapy, and two further samples were obtained on day 3 and at the end of the treatment for CRP and suPAR. RESULTS: The mean gestational ages of patient and control groups was similar. The median level of initial suPAR was 18.8 ng/mL (range 6.8-30.1 ng/mL) in the patient groups, and 6.0 ng/mL (range 3.7-10.8 ng/mL) in the control group (P < 0.001). A significant decrease in suPAR level was observed from the inclusion to the third day and end of the treatment (P < 0.001). The area under the curve (AUC) for suPAR is 0.959 (95% Cl: 0.919-0.999) and for CRP is 0.782 (95% Cl: 0.669-0.895). At a cut-off value of 11.3 ng/mL for suPAR the specificity was 100%, and the sensitivity was 82.5%. There was a positive correlation between laboratory values of CRP and suPAR (r: 0.359, P = 0.003). CONCLUSION: This is the first study that investigated the levels of suPAR in neonates and our results demonstrate that suPAR is a powerful marker of inflammation in infants with sepsis.

RESUMEN

OBJECTIVE: The aim of this study was to evaluate the effects of umbilical cord milking (UCM) on the need for packed red blood cell (PRBC) transfusion and hematologic and hemodynamic parameters in very-low-birth-weight infants. METHODS: The infants were randomized into 2 groups: group 1 (UCM) and group 2 (control). The primary outcome was the number of PRBC transfusions during the first 35 days of life. The secondary outcome measures were the hemodynamic variables during the first 24 hours of life. RESULTS: A total of 44 infants were included with 22 infants in each group. Two of 21 infants in group 1 and 4 of 21 infants in group 2 received transfusion in the first 3 days of life (P=0.384). The number and volume of PRBC transfusions were similar in both groups. However, the levels of hemoglobin (Hb) at the first and 24th hour of life were significantly higher in group 1. Phlebotomy volume was found as a statistically significant risk factor for the need for PRBC transfusion (P=0.005). CONCLUSIONS: UCM in delivery room results in a higher Hb level in the first day of life. In these groups of infants, phlebotomy losses may impact the transfusion need.

RESUMEN

BACKGROUND: Device-associated healthcare-acquired infections (DA-HAI) pose a threat to patient safety, particularly in the intensive care unit (ICU). We report the results of the International Infection Control Consortium (INICC) study conducted in Turkey from August 2003 through October 2012. METHODS: A DA-HAI surveillance study in 63 adult, paediatric ICUs and neonatal ICUs (NICUs) from 29 hospitals, in 19 cities using the methods and definitions of the U.S. NHSN and INICC methods. RESULTS: We collected prospective data from 94,498 ICU patients for 647,316 bed days. Pooled DA-HAI rates for adult and paediatric ICUs were 11.1 central line-associated bloodstream infections (CLABSIs) per 1000 central line (CL)-days, 21.4 ventilator-associated pneumonias (VAPs) per 1000 mechanical ventilator (MV)-days and 7.5 catheter-associated urinary tract infections (CAUTIs) per 1000 urinary catheter-days. Pooled DA-HAI rates for NICUs were 30 CLABSIs per 1000 CL-days, and 15.8 VAPs per 1000 MV-days. Extra length of stay (LOS) in adult and paediatric ICUs was 19.4 for CLABSI, 8.7 for VAP and 10.1 for CAUTI. Extra LOS in NICUs was 13.1 for patients with CLABSI and 16.2 for patients with VAP. Extra crude mortality was 12% for CLABSI, 19.4% for VAP and 10.5% for CAUTI in ICUs, and 15.4% for CLABSI and 10.5% for VAP in NICUs. Pooled device use (DU) ratios for adult and paediatric ICUs were 0.54 for MV, 0.65 for CL and 0.88 for UC, and 0.12 for MV, and 0.09 for CL in NICUs. The CLABSI rate was 8.5 per 1,000 CL days in the Medical Surgical ICUs included in this study, which is higher than the INICC report rate of 4.9, and more than eight times higher than the NHSN rate of 0.9. Similarly, the VAP and CAUTI rates were higher compared with U.S. NHSN (22.3 vs. 1.1 for VAP; 7.9 vs. 1.2 for CAUTI) and with the INICC report (22.3 vs. 16.5 in VAP; 7.9 vs. 5.3 in CAUTI). CONCLUSIONS: DA-HAI rates and DU ratios in our ICUs were higher than those reported in the INICC global report and in the US NHSN report.

RESUMEN

OBJECTIVE: Lactoferrin (LF) is effective in the prevention of sepsis in very low birth weight (VLBW) neonates. T-regulatory cells (Tregs) are important subsets of T lymphocytes that control pathogen-specific immune responses and are essential for intestinal immune homoeostasis. The aim of the present study is to determine whether oral LF at a dosage of 200 mg/d reduces nosocomial sepsis episodes and necrotizing enterocolitis (NEC) in premature infants and to evaluate the possible effects of LF on Treg levels. STUDY DESIGN: In this prospective, placebo-controlled, double-blind, randomized trial, infants either VLBW or born before 32 weeks were assigned to receive either placebo (n = 25), or 200 mg LF (n = 25) daily throughout hospitalization. Episodes of culture proven nosocomial sepsis and NEC were recorded. The level of FOXP3 + CD4 + CD25hi lymphocytes was studied by flow cytometry at birth and discharge. A third comparison was made with healthy term neonates (n = 16). RESULTS: Fewer sepsis episodes were observed in LF-treated infants (4.4 vs. 17.3/1,000 patient days, p = 0.007) with none developing NEC, without statistical significance. Treg levels at birth and discharge were similar, while preterm infants showed significantly lower levels than term controls. However, individual increases in Treg levels were higher in the LF group. CONCLUSION: LF prophylaxis reduced nosocomial sepsis episodes. Treg levels in preterm infants were lower than in term infants and an increase of Treg levels under LF prophylaxis was observed. Increase in Treg levels can be the mechanism for protective effects of LF on nosocomial sepsis.

RESUMEN

OBJECTIVES: To describe the efficacy of intravenous colistin on clinical and microbiological outcomes in preterm infants with nosocomial sepsis in neonatal intensive care unit (NICU) and define adverse events observed with this treatment. METHODS: The records of preterm infants who received colistin with or without positive cultures in the NICU were retrospectively reviewed. Patients were evaluated for response to therapy and side effects. RESULTS: A total of 21 preterm infants with medians of 28 weeks (23-36) gestational age and 870 g (620-2,650) birth weight were included. The median duration and dose of colistin therapy were 9 days (3-26) and 3 mg/kg/d (2-5). Recovery rate in patients including all with/without positive culture was 81% (17/21). Microbiological clearance by colistin was 69% (9/13). The major side effect observed was acute kidney injury (19%). At least 24% of infants required electrolyte supplementation during the colistin therapy. Magnesium levels were significantly lower at the end of the colistin therapy (p < 0.001). Acute kidney injury and electrolyte disturbances including hypomagnesemia were reversible in all surviving patients. CONCLUSION: We suggest that renal function tests and serum electrolytes should be monitored closely and replaced in case of any need during the colistin therapy in preterm infants.

RESUMEN

This study aimed to investigate the influence of prothrombotic risk factors on long-term outcomes of patients with perinatal arterial ischemic stroke. The study was conducted through an analysis of monitoring results that were regularly maintained for approximately 20 years at a tertiary stroke-monitoring center. The study assessed prothrombotic risk factors, radiological area of involvement, clinical presentation, treatments, clinical outcomes, and long-term outcomes of the 48 patients included in the study, with a mean monitoring time of 77.6 ± 45.7 months (range: 6-204). Our results showed that the presence of prothrombotic risk factors did not affect long-term outcomes. However, patients with middle cerebral artery infarction had the highest risk of developing cerebral palsy, whereas those with presumed stroke had the highest risk of developing epilepsy. This study suggests that prothrombotic risk factors should not be evaluated during the acute stage unless there is a strong suspicion of the patient's history, and prevention or early diagnosis of presumed stroke patients will positively impact their long-term prognosis.

RESUMEN

Acquired Bartter-like syndrome (BLS), characterized by hypokalemic metabolic alkalosis, hypomagnesemia, hypocalcemia, and normal kidney function, can be induced by diuretics or antibiotics. It is a very rare condition and only anecdotal cases mostly in adults were reported. Although tubulopathy associated with colistin was reported in adults, to the best of our knowledge, colistin-associated BLS neither in adults nor in children has been reported in the literature. We here report a-28-week, 740 g female preterm infant who developed BLS just after colistin treatment for Acinetobacter baumannii infection and recovered few days after the drug cessation, and discuss the possible association of colistin and tubulopathy. More research on colistin pharmacokinetics and pharmacodynamics in critically ill patients and preterm infants is needed to guide adequate colistin dosing at the least toxicity.

RESUMEN

Streptococcus pneumoniae infections which are relatively unusual in the neonates, are associated with substantial morbidity and mortality. Although S.pneumoniae has more than 90 serotypes, invasive disease is more common with certain serotypes. Pneumococcal polysaccharide and conjugate vaccines are developed against the serotypes that cause invasive disease. Until now invasive pneumococcal diseases have been defined due to various serotypes in the neonatal period. Here we present a neonate with an invasive pneumococcal disease due to S.pneumoniae serotype 7F which has not yet been reported in the literature. A 3180 g infant was born to a healthy 31 year old primigravida by normal vaginal delivery at 39 weeks gestation. Since the infant developed uneasiness, decreased sucking reflex and respiratory difficulty at postnatal 10th hour, he was admitted to the neonatal intensive care unit. Upon admission to intensive care unit mechanical ventilation, fluid replacement and empirical penicillin G and netilmycin had been initiated since the patient had hypotension, hypothermia and tachycardia. The infant later developed severe metabolic acidosis and had anemia, leukocytosis and high CRP values. CSF culture revealed no bacterial growth, however, S.pneumoniae was grown in the blood culture. The isolate was identified as serotype 7F by capsule swelling reaction. The vaginal specimen taken from the mother for the determination of the infectious foci revealed no pathogen growth. The patient's general condition improved after the second day of supportive treatment and antibiotherapy. Since the isolate was penicillin susceptible, the treatment continued with penicillin G and netilmycin for 14 days and the case was discharged with cure. This case was presented to emphasize that S.pneumoniae serotype 7F might lead to invasive disease not only during childhood but also during early neonatal period.

RESUMEN

INTRODUCTION: Accurate assessment of the risk for bronchopulmonary dysplasia (BPD) is critical to determine the prognosis and identify infants who will benefit from preventive therapies. Clinical prediction models can support the identification of high-risk patients. In this study, we investigated the potential risk factors for BPD and compared machine learning models for predicting the outcome of BPD/death on days 1, 7, 14, and 28 in preterm infants. We also developed a local BPD estimator. METHODS: This study involved 124 infants. We evaluated the composite outcome of BPD/death at a postmenstrual age of 36 weeks and identified risk factors that would improve BPD/death prediction. SPSS for Windows Version 11.5 and Weka 3.9 software were used for the data analysis. RESULTS: To evaluate the combined effect of all variables, all risk factors were taken into consideration. Gestational age, birth weight, mode of respiratory support, intraventricular hemorrhage, necrotizing enterocolitis, surfactant requirement, and late-onset sepsis were risk factors on postnatal days 7, 14, and 28. In a comparison of four different time points (postnatal days 1, 7, 14, and 28), the day 7 model provided the best prediction. According to this model, when a patient was diagnosed with BPD/death, the accuracy rate was 89.5%. CONCLUSION: The postnatal day 7 model was the best predictor of BPD or death. Future validation studies will help identify infants who may benefit from preventive therapies and develop individualized care.

RESUMEN

In the neonatal intensive care units (NICU), epicutaneo-caval catheters (ECCs) are common alternative vascular routes. Pericardial effusion (PCE) and cardiac tamponade (CT) are rare but serious complications in infants with ECCs. It may be asymptomatic or present with a variety of significant clinical signs, including dyspnea, bradycardia, sudden asystole, and hypotension. If untreated, PCE can be fatal. This report presents, three cases of ECC-associated PCE/CT during NICU stay. All three patients were born before 30 weeks of gestation and weighed less than 1500 g. Echocardiography was used for diagnosis all patients. PCE/CT was detected incidentally in one patient and after hemodynamic deterioration in the other two. In one patient, CT was developed due to catheter malposition, and the other two patient, the catheter tip was found in the right atrium. PCE did not recur in any of the patients after pericardial fluid was drained and the catheters were removed. No PCE/CT-related deaths were observed. In all three patients, X-ray was used to evaluate the location of the catheter tips. However, after clinical deterioration, echocardiography showed that in the first two cases the tips were actually in the right atrium. Real-time ultrasound was suggested with strong evidence to evaluate the location of the catheter tip and to detect secondary malapposition. PCE/CT should be considered in the presence of unexplained and refractory respiratory distress, abnormal heart rate and blood pressure, and metabolic acidosis in a neonate with ECC. Early diagnosis and prompt pericardiocentesis are essential to reduce mortality and improve prognosis. Prospective studies with educational interventions should be designed to demonstrate that the use of point-of-care ultrasound (POCUS) can be easily acquired and may reduce complications.
