ABSTRACT

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..

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

BACKGROUND: Toilet training is a significant developmental milestone for children. During the process of toilet training, voiding and defecation problems may develop, which have a major adverse impact on the child's quality of life (QoL). The aim of this study was to assess voiding and defecation problems in the process of toilet training and evaluate how these issues influenced the children's QoL. METHODS: The children included in the study were followed up at the Department of Social Pediatrics, Ankara University School of Medicine. Participants were surveyed via a questionnaire that included sociodemographic features, the toilet training process, and the Pediatric Quality of Life Inventory. RESULTS: The study included 177 children and their parents. There was no correlation between the parents' age, sociodemographic features, or the timing of the start of toilet training. Voiding problems were found in 55.6% and defecation problems in 23.6% of the children included in the study. Urinary retention during play and nocturnal enuresis were more frequent in the children toilet trained at 25-36 months of age. The self-reported QoL scores in children with voiding problems and with both voiding and defecation problems were lower than those in children did not have any problems. CONCLUSIONS: Even if a child has been toilet trained, it is essential to investigate daily urination and defecation habits at every follow-up visit and to discuss with families when a physician should be consulted.

ABSTRACT

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.

ABSTRACT

Objectives: To identify urinary catheter (UC)-associated urinary tract infections (CAUTI) incidence and risk factors (RF) in nine Middle Eastern countries. Methods: We conducted a prospective cohort study between 1 January 2014 and 2 December 2022 in 212 intensive care units (ICUs) of 67 hospitals in 38 cities in nine Middle Eastern countries (Bahrain, Egypt, Jordan, Kuwait, Lebanon, Morocco, Saudi Arabia, Turkey, and the UAE). To estimate CAUTI incidence, we used the number of UC days as denominator and the number of CAUTIs as numerator. To estimate CAUTI RFs, we analyzed the following 10 variables using multiple logistic regression: patient sex, age, length of stay (LOS) before CAUTI acquisition, UC-days before CAUTI acquisition, UC-device utilization (DU) ratio, hospitalization type, ICU type, facility-ownership, country income level classified by World Bank, and time period. Results: Among 50 637 patients hospitalized for 434 523 patient days, there were 580 cases of acquired CAUTIs. The pooled CAUTI rate per 1000 UC days was 1.84. The following variables were independently associated with CAUTI: age, rising risk 1.0% yearly (adjusted odds ratio [aOR] = 1.01, 95% CI: 1.01-1.02; p < 0.0001); female sex (aOR = 1.31, 95% CI: 1.09-1.56; p < 0.0001); LOS before CAUTI acquisition, rising risk 6.0% daily (aOR = 1.06, 95% CI: 1.05-1.06; p < 0.0001); and UC/DU ratio (aOR = 1.11, 95% CI: 1.06-1.14; p < 0.0001). Patients from lower-middle-income countries (aOR = 4.11, 95% CI: 2.49-6.76; p < 0.0001) had a similar CAUTI risk to the upper-middle countries (aOR = 3.75, 95% CI: 1.83-7.68; p < 0.0001). The type of ICU with the highest risk for CAUTI was neurologic ICU (aOR = 27.35, 95% CI: 23.03-33.12; p < 0.0001), followed by medical ICU (aOR = 6.18, 95% CI: 2.07-18.53; p < 0.0001) when compared to cardiothoracic ICU. The periods 2014-2016 (aOR = 7.36, 95% CI: 5.48-23.96; p < 0.001) and 2017-2019 (aOR = 1.15, 95% CI: 3.46-15.61; p < 0.001) had a similar risk to each other, but a higher risk compared to 2020-2022. Conclusions: The following CAUTI RFs are unlikely to change: age, sex, ICU type, and country income level. Based on these findings, it is suggested to focus on reducing LOS, UC/DU ratio, and implementing evidence-based CAUTI prevention recommendations.

ABSTRACT

Objective: Non-invasive respiratory support strategies are known to reduce the complications of invasive mechanical ventilation in preterm infants. Nasal continuous positive airway pressure (NCPAP) and nasal intermittent positive pressure ventilation (NIPPV) are commonly used ones. The recent meta-analyses indicated that early NIPPV did appear to be superior to NCPAP for decreasing respiratory failure and the need for intubation among preterm infants with respiratory distress syndrome (RDS). The aim of the study was to compare the short-term outcomes of extremely preterm infants who received NCPAP or NIPPV as an initial treatment of RDS. Methods: This retrospective study included infants born before 29 weeks' gestation between 1 January 2018 and 31 December 2021 who received non-invasive respiratory support with NCPAP or NIPPV. For every infant included in the cohort, only the first episode of NCPAP or NIPPV as initial treatment was evaluated. The primary outcome was the need for intubation within 72 h, and the secondary outcomes were the need for intubation within 7 days, administration of surfactant, prematurity-related morbidities, mortality, and death or bronchopulmonary dysplasia (BPD). Results: During the study period, there were 116 inborn admissions of preterm infants born <29 weeks' gestation and 60 of them met the inclusion criteria. Of these, 31 (52%) infants received NCPAP while 29 (48%) infants received NIPPV at the first hours after birth. There were no differences in the baseline demographics between the groups (p > 0.05). Blood gas parameters (pH, pCO2, HCO3, and lactate) at admission were not different. The need for intubation within 72 h as the primary outcome was similar between NCPAP and NIPPV groups (35.5 vs. 34.5%, p = 0.935). The rates of surfactant requirement, need for intubation within 7 days, prematurity-related morbidities, mortality, and death/BPD were similar among the groups (p > 0.05). Conclusion: Nasal intermittent positive pressure ventilation is non-inferior to NCPAP as an initial treatment in extremely preterm infants with RDS. Although the rate of intubation in the first week, mortality, and BPD did not differ between groups, additional studies are needed and the synchronization of NIPPV should be evaluated.
