Objective: Preterm infants have high zinc (Zn) requirements and are generally believed to be in a negative Zn balance in the early period of life. In this study, we aimed to investigate the effect of high-dose Zn supplementation in very low birth weight (VLBW: infants with birth weight < 1.5 kg) infants on feeding intolerance and development of mortality and/or morbidities including necrotizing enterocolitis (NEC) and late-onset sepsis (LOS)., Study Design: This is a prospective randomized trial. VLBW preterm infants with gestational age of <32 weeks were randomly allocated on the seventh day of life to receive extra amount of supplemental Zn along with the enteral feedings (9 + 3 mg), besides regular low-dose supplementation (3 mg), from enrollment until discharge. Outcome measures were feeding intolerance, NEC (stage ≥ 2), LOS, and mortality., Results: A total of 195 infants (97 from study group and 98 from control group) were analyzed. A total of 46 (47.4%) infants in the study group and 64 (65.3%) infants in the control group ended up with feeding intolerance ( p  = 0.012). NEC was observed in 11 infants (11.2%) in the control group and only 1 infant (1%) in the study group ( p  = 0.003). There was a negative correlation between high-dose Zn supplementation and number of culture-proven LOS episodes ( p  = 0.041). This significance was also present for clinical sepsis, being higher in the control group ( p  = 0.029). No relationship between high-dose Zn supplementation and mortality and other morbidities (hemodynamically significant patent ductus arteriosus, bronchopulmonary dysplasia, retinopathy of prematurity, and severe intraventricular hemorrhage) was observed., Conclusion: Zn supplementation for VLBW infants is found to be effective to decrease feeding intolerance, NEC, and LOS episodes in this vulnerable population. Current data support the supplementation of VLBW infants with higher than regular dose of Zn., Key Points: · Higher dose of Zn supplementation is shown to be a beneficial intervention in VLBW infants.. · Zn may decrease feeding intolerance, sepsis or NEC.. · Higher than regular dose of Zn seems to be safe.., Competing Interests: None declared., (Thieme.

Background: The transition to full enteral feeding is important for ensuring adequate growth in preterm infants., Aims: The aim of this study was to investigate the effects of two different intermittent feeding methods on the transition to full enteral feeding in preterm infants., Study Design: A prospective, randomized controlled study was conducted in a neonatology and perinatology center., Subjects: Preterm infants with a gestational age between 24 + 0/7 and 31 + 6/7 were included in this study. They were divided into two groups: the SIF (slow infusion feeding) group and the IBF (intermittent bolus feeding) group. In the SIF group, feed volumes were administered over one hour using an infusion pump through an orogastric tube, with feeding occurring every three hours. The IBF group received enteral feeding using a gravity-based technique with a syringe through an orogastric tube, completed within 10 to 30 min., Outcome Measures: The primary outcome was the achievement of full enteral feeding and the occurrence of feeding intolerance., Results: A total of 103 infants were enrolled in the study (50 in SIF and 53 in IBF). The time to achieve full enteral feeding did not differ significantly between the two groups ( p = 0.20). The SIF group had significantly fewer occurrences in which gastric residual volume exceeded 50% ( p = 0.01). Moreover, the SIF group had a significantly shorter duration of non-per-oral (NPO) status than the IBF group ( p = 0.03)., Conclusions: It is our contention that the use of the SIF method as an alternative feeding method is appropriate for infants with feeding intolerance and those at high risk of feeding intolerance.

Introduction: Caffeine is one of the most used drugs in the neonatal intensive care units (NICUs). It is widely regarded as beneficial in preventing many morbidities by reducing apnea of prematurity and improving respiratory functions., Methods: Premature infants with gestational ages >25 and <32 weeks who were hospitalized in the NICU between 2008 and 2013 and survived up to discharge were retrospectively analyzed. Infants treated with prophylactic caffeine were compared with historical controls born in 2008 and did not receive caffeine treatment. Maternal and neonatal characteristics and common neonatal morbidities were recorded., Results: A total of 475 patients were analyzed. The patients receiving caffeine were classified as Group 1 ( n  = 355), and the patients not receiving caffeine were classified as Group 2 ( n  = 120). Despite the higher incidence of respiratory distress syndrome requiring surfactant therapy and a longer duration of respiratory support in Group 2, the rates of bronchopulmonary dysplasia (BPD) and most other common morbidities were quite comparable. The frequency of apnea was statistically lower in the group that received caffeine prophylaxis ( p  < 0.01)., Conclusion: In this retrospective cohort analysis, we found that caffeine prophylaxis significantly decreased apnea attacks however does not prevent respiratory morbidity such as BPD., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Yavanoglu Atay, Kanmaz Kutman, Bidev, Bozkurt Kalyoncu and Oğuz.)

Objective: Urinary tract infection (UTI) is a disease that can cause significant complications in the neonatal period. The thiol-disulfide homeostasis is one of the important antioxidant defense mechanisms. The purpose of this study is to show the relationship between UTI and thiol-disulfide homeostasis in newborns., Study Design: In this prospective study, 40 newborns with UTI and 40 healthy controls were included. Thiol-disulfide tests (disulfide, native thiol, and total thiol levels) and septic screening tests were performed before and after antibiotherapy in UTI group. The control group was selected from healthy newborns who applied to the outpatient clinic., Results: The C-reactive protein and interleukin-6 levels were higher, while native thiol and native thiol/total thiol ratio were significantly lower in pretreatment group compared with posttreatment and control group. Also, the levels of disulfide, ischemia modified albumin, disulfide/native thiol ratio, and disulfide/total thiol ratio were higher in pretreatment group compared with posttreatment group., Conclusion: The thiol-disulfide homeostasis is an important indicator of oxidative stress during infections. It is valuable to be detected with small amounts of serum in newborns. These molecules can be used to support the diagnosis of UTI in the newborn. Further studies are needed to define the role of thiol-disulfide homeostasis in the UTI of newborn., Key Points: · The thiol-disulfide homeostasis can be an important indicator of oxidative stress during infections such as UTI.. · The thiol-disulfide homeostasis of newborn is valuable to be detected with small amounts of serum in neonatal period.. · Laboratory tests such as white blood cell count, erythrocyte sedimentation rate, and C-reactive protein are not significantly different in UTIs.., Competing Interests: None declared., (Thieme.

Objective: To determine the effect of two different feeding strategies on time to achieve full enteral feeding and the incidence of feeding intolerance in preterm infants with birth weight ≤1250 g., Methods: A prospective randomized trial (NCT02913677) conducted at a tertiary level neonatal intensive care unit. Preterm infants with birth weight ≤1250 g were randomly allocated to either prolonged minimal enteral nutrition (MEN) in which feed volumes were not increased for five days or early feeding advancement groups in which feed volumes were advanced by 20-25 ml/kg/d until 150 ml/kg/d feed volume was achieved. The primary outcomes were time to reach full enteral feeding sustained for 72 h and incidence of feeding intolerance., Results: A total of 199 infants (99 in prolonged MEN and 100 in early feeding advancement groups) were involved in the study. No statistically significant differences were observed in time to achieve full enteral feeding and feeding intolerance. Daily weight gain (19 versus 16 g; p  < .001) was significantly higher in prolonged MEN group. There were no significant differences in weight percentiles and z -scores at discharge. Duration of hospitalization was comparable between the groups. The overall incidence of late onset sepsis and culture proven sepsis was similar in both groups ( p  = .92 and p  = .22, respectively). Incidence of necrotizing enterocolitis (NEC) was 5% in early feeding advancement group, whereas no case of NEC was observed in prolonged MEN group ( p  = .06)., Conclusions: Prolonged MEN is not associated with a delay in time to achieve full enteral feedings. It may even provide an advantage for development of NEC in extremely low birth weight infants., Trial Registration: Clinical Trials.gov: NCT02913677.

Nemaline myopathy (NM) is a heterogeneous disorder defined by the presence of rod-shaped structures known as nemaline bodies or rods. The diagnosis is based on muscle weakness, combined with visualization of nemaline bodies on muscle biopsy. There is no curative treatment for nemaline myopathy. Therapeutic strategies for this condition are symptomatic and empirical. Herein, we present a newborn with severe respiratory failure and generalized muscle weakness, who was diagnosed as NM by muscle biopsy. The patient experienced remarkable decrease in sialorrhea and improvement of spontaneous movements after L-tyrosine treatment. This case is presented to emphasize the importance of muscle biopsy in the differential diagnosis of severe hypotonia during neonatal period and a possible benefit of L-tyrosine supplementation for decreasing sialorrhea and restoring muscle strength., Competing Interests: The authors report no conflicts of interest in this work., (Sociedad Argentina de Pediatría.)

Fryns anophthalmia-plus syndrome is a rare syndrome with clinical diversity primarily including anophthalmia/microphthalmia, facial clefts, cleft lip/palate, ear and nasal deformities. Here we present two different cases of APS with anopthalmia/microphthalmia, cleft palate, low set ears, ventriculomegaly and one of which had intestinal non-fixation anomaly not described in the literature before.

Purpose: Protecting patients from the acute and/or chronic toxicity of antineoplastic therapy has become a major concern of oncology centers around the world. Glutamine has been used as a multisystemic protective agent to minimize the side effects arising from the treatment of childhood cancers. In this study, the effect of intravenous glutamine supplementation was investigated in children receiving chemotherapy for non-Hodgkin lymphoma., Methods: Twelve children, of 48 to 120 months of age, and who had non-Hodgkin lymphoma were enrolled in the study. Thirty chemotherapy courses were given in combination with glutamine, and 31 chemotherapy courses were given without glutamine. Glutamine was given intravenously for 7 days, at a dose of 0.4 g/kg/d. Patients were evaluated in each course with regard to gastrointestinal, mucosal, and hematological toxicities., Results: There were no significant differences in the hematological parameters between the 2 groups. The requirements for red blood cells and platelets during the chemotherapy courses were similar in both groups (P=0.64 and 0.40, respectively). Patients supplemented with glutamine developed mucositis in 21 of 30 courses (70%) and patients without glutamine supplements developed mucositis in 23 of 31 courses (74%). The mean duration of mucositis and the mean mucositis score in each course were similar between the 2 groups. In addition, gastrointestinal system and hepatic toxicity did not differ between groups. The mean duration of febrile neutropenia and the length of hospitalization were also similar in both groups (P=0.09 and 0.13, respectively)., Conclusions: Parenteral glutamine supplementation has no effect on mucositis, fever and febrile neutropenia, length of hospitalization, red blood cell, and platelet requirements, and hematological, gastrointestinal, and hepatic toxicities in children receiving severe chemotherapy.
