RESUMO

BACKGROUND: The use of cerebral oximetry monitoring in the care of extremely preterm infants is increasing. However, evidence that its use improves clinical outcomes is lacking. METHODS: In this randomized, phase 3 trial conducted at 70 sites in 17 countries, we assigned extremely preterm infants (gestational age, <28 weeks), within 6 hours after birth, to receive treatment guided by cerebral oximetry monitoring for the first 72 hours after birth or to receive usual care. The primary outcome was a composite of death or severe brain injury on cerebral ultrasonography at 36 weeks' postmenstrual age. Serious adverse events that were assessed were death, severe brain injury, bronchopulmonary dysplasia, retinopathy of prematurity, necrotizing enterocolitis, and late-onset sepsis. RESULTS: A total of 1601 infants underwent randomization and 1579 (98.6%) were evaluated for the primary outcome. At 36 weeks' postmenstrual age, death or severe brain injury had occurred in 272 of 772 infants (35.2%) in the cerebral oximetry group, as compared with 274 of 807 infants (34.0%) in the usual-care group (relative risk with cerebral oximetry, 1.03; 95% confidence interval, 0.90 to 1.18; P = 0.64). The incidence of serious adverse events did not differ between the two groups. CONCLUSIONS: In extremely preterm infants, treatment guided by cerebral oximetry monitoring for the first 72 hours after birth was not associated with a lower incidence of death or severe brain injury at 36 weeks' postmenstrual age than usual care.

RESUMO

BACKGROUND: Povidone-iodine (10%; PI) and 2% chlorhexidine in 70% isopropyl alcohol (CHG-IA) solutions are among the most widely used disinfectants in the neonatal intensive care units. This study compares the use of these disinfectants and helps decide which is superior to the other for neonatal use. METHODS: All term and preterm infants born and hospitalized in Bursa Uludag University Hospital between July 2018-March 2020 were included. The infants were randomized into two disinfectant groups before birth. The application site was cleaned with the assigned disinfectant before intervention. The infants were screened for rates of neonatal sepsis, thyroid-stimulating hormone (TSH) levels, free thyroxine (fT4) levels, skin reactions to the assigned solution, and acute neurological side effects. RESULTS: We enrolled 208 term and preterm infants (PI:104 vs. CHG-IA: 104) in the study. The prematurity rates were identical (PI: 74.0%; CHG-IA: 72.1%; p = 0.755). Neonatal sepsis rates among these groups were not statistically different (PI: 8.7%; CHG-IA: 4.8%; p = 0.406). The median TSH value of the PI group was high (4.05 mIU/L) in comparison with that of the CHG-IA group (3.09 mIU/L; p = 0.016). No cutaneous or neurological side effects were recorded in patients treated with CHG-IA solution. CONCLUSIONS: Although these two solutions were equally protective against infections, the CHG-IA solution was a better alternative to PI for neonatal use. Considering that the PI solution may be responsible for impaired thyroid function, the CHG-IA solution is a good alternative because it provides sufficient protection with a safer adverse effect profile.

RESUMO

OBJECTIVE: Caffeine treatment is routinely used in premature infants to prevent development of apnea and bronchopulmonary dysplasia. Although a limited number of studies have reported that early caffeine treatment may cause development of necrotizing enterocolitis (NEC) by reducing mesenteric blood flow, this issue is still under discussion. The aim of this study is to investigate the possible effect of different onset times of early caffeine treatment on mesenteric tissue oxygen saturation and NEC development in premature infants. STUDY DESIGN: A total of 87 preterm infants with ≤1,250-g birth weight (BW) was included in this prospective study. The cases were randomized as group 1 (first 24 hours) and group 2 (72nd hour) caffeine treatment groups and monitored by near-infrared spectroscopy (NIRS) for 72 hours from the time of admission until cerebral, renal, and mesenteric tissue oxygen saturations (rSO2) were recorded. The cases were followed-up to the 40th week in terms of NEC and other neonatal morbidities. RESULTS: A total of 87 infants were included in the study, including 45 in group 1 and 42 in group 2. The groups were similar in terms of demographic characteristics. The incidence of NEC in group 1 (20%) was higher in comparison to group 2 (9%). The mesenteric rSO2 values in the first 72 hours of group 1 were lower than those of group 2. Low gestational week, BW, and late onset of enteral feeding were found to be other significant risk factors for NEC. CONCLUSION: In this study, mesenteric tissue oxygenation was lower, and NEC was higher in group 1. Mesenteric rSO2 measurements may be useful in predicting the development of NEC in patients receiving early caffeine therapy. KEY POINTS: · Onset time of early caffeine treatment may effect on mesenteric tissue oxygen saturation.. · Caffeine treatment that onset in the first 24 hours may be associated with NEC development.. · Mesenteric rSO2 measurements may be useful in patients receiving early caffeine therapy..

RESUMO

OBJECTIVE: Portable X-rays remain one of the most frequently used diagnostic procedures in neonatal intensive care units (NICU). Premature infants are more sensitive to radiation-induced harmful effects. Dangers from diagnostic radiation can occur with stochastic effects. We aimed to determine the radiation exposure in premature infants and staff and determine the scattering during X-ray examinations in the NICU. STUDY DESIGN: In this prospective study, dosimeters were placed on premature infants who were ≤1,250 g at birth and ≤30 weeks of gestational age who stayed in the NICU for at least 4 weeks. The doses were measured at each X-ray examination during their stay. The measurements of the nurses and the doctors in the NICU were also performed with dosimeters over the 1-month period. Other dosimeters were placed in certain areas outside the incubator and the results were obtained after 1 month. RESULTS: The mean radiation exposure of the 10 premature infants, monitored with dosimeters, was 3.65 ± 2.44 mGy. The mean skin dose of the six staff was 0.087 ± 0.0998 mSV. The mean scattered dose was 67.9 ± 26.5 µGy. CONCLUSION: Relatively high exposures were observed in 90% of the patients and two staff. The radiation exposure levels of premature infants and staff may need to be monitored continuously. KEY POINTS: · The premature infants are exposed to radiation due to the bedside X-rays.. · The radiation exposure levels of premature infants and staff may need to be monitored continuously.. · Measures and alternative methods to reduce radiation exposure should be encouraged..

RESUMO

Importance: The long-term effects of surfactant administration via a thin catheter (minimally invasive surfactant therapy [MIST]) in preterm infants with respiratory distress syndrome remain to be definitively clarified. Objective: To examine the effect of MIST on death or neurodevelopmental disability (NDD) at 2 years' corrected age. Design, Setting, and Participants: Follow-up study of a randomized clinical trial with blinding of clinicians and outcome assessors conducted in 33 tertiary-level neonatal intensive care units in 11 countries. The trial included 486 infants with a gestational age of 25 to 28 weeks supported with continuous positive airway pressure (CPAP). Collection of follow-up data at 2 years' corrected age was completed on December 9, 2022. Interventions: Infants assigned to MIST (n = 242) received exogenous surfactant (200 mg/kg poractant alfa) via a thin catheter; those assigned to the control group (n = 244) received sham treatment. Main Outcomes and Measures: The key secondary outcome of death or moderate to severe NDD was assessed at 2 years' corrected age. Other secondary outcomes included components of this composite outcome, as well as hospitalizations for respiratory illness and parent-reported wheezing or breathing difficulty in the first 2 years. Results: Among the 486 infants randomized, 453 had follow-up data available (median gestation, 27.3 weeks; 228 females [50.3%]); data on the key secondary outcome were available in 434 infants. Death or NDD occurred in 78 infants (36.3%) in the MIST group and 79 (36.1%) in the control group (risk difference, 0% [95% CI, -7.6% to 7.7%]; relative risk [RR], 1.0 [95% CI, 0.81-1.24]); components of this outcome did not differ significantly between groups. Secondary respiratory outcomes favored the MIST group. Hospitalization with respiratory illness occurred in 49 infants (25.1%) in the MIST group vs 78 (38.2%) in the control group (RR, 0.66 [95% CI, 0.54-0.81]) and parent-reported wheezing or breathing difficulty in 73 (40.6%) vs 104 (53.6%), respectively (RR, 0.76 [95% CI, 0.63-0.90]). Conclusions and Relevance: In this follow-up study of a randomized clinical trial of preterm infants with respiratory distress syndrome supported with CPAP, MIST compared with sham treatment did not reduce the incidence of death or NDD by 2 years of age. However, infants who received MIST had lower rates of adverse respiratory outcomes during their first 2 years of life. Trial Registration: anzctr.org.au Identifier: ACTRN12611000916943.

RESUMO

PURPOSE: This study aimed to assess the written language skills of children with auditory brainstem implants (ABI). METHODS: In this study, 15 children (from second to eighth grades) with ABI were evaluated for their written language abilities using a written expression skill assessment form. Five different features of written expression points were scored and analyzed, yielding a composite score for written expression skills. RESULTS: This study showed that all children with ABI needed more verbal cues than spontaneously written samples. Moreover, these children used short and simple sentences with limited vocabulary and repeated words and sentences. Furthermore, these children were deficient in writing an introduction, the body, and the conclusion paragraphs and could not write events in a logical sequence. CONCLUSIONS: The written language skills of children with ABI depend on age at implantation, duration of implant use, and additional handicaps. Written expression skills in children with ABI are highly complex skills. The findings highlight the importance of ABI during the critical language development period and the enhancement of training programs for written language skills in children who underwent ABI.

RESUMO

INTRODUCTION: Children with cleft palate exhibit differences in the 4 temporal components of nasalization (nasal onset and offset intervals, nasal consonant duration, and total speech duration), with various patterns having been noted based on different languages. Thus, the current study aimed to examine the temporal aspects of velopharyngeal closure in children with and without cleft palate; this is the first study to do so in the Turkish language. METHODS: This study evaluated and compared the 4 temporal characteristics of velopharyngeal closure in children (aged 6-10 years) with (n = 28) and without (n = 28) cleft palate using nonword consonant and vowel speech samples, including the bilabial nasal-to-stop combination /mp/ and the velar nasal-to-stop combination /ηk/. Acoustic data were recorded using a nasometer, after which acoustic waveforms were examined to determine the 4 temporal components of nasalization. Flexible nasoendoscopy was then used to evaluate velopharyngeal closure patterns. RESULTS: With regard to the 4 closure patterns, significant differences in the nasal offset interval (F4-25 = 10.213, p = 0.04; p < 0.05) and the nasal consonant duration ratio (F4-25 = 12.987, p = 0.02; p < 0.05) were observed for only /ampa/. The coronal closure pattern showed the longest closure duration (0.74 s). Children with cleft palate showed prolonged temporal parameters in all 4 characteristics, reflecting oral-nasal resonance imbalances. In particular, the low vowel sound /a/ was significantly more prolonged than the high vowel sounds /i/ and /u/. CONCLUSIONS: The examined temporal parameters offer more accurate characterizations of velopharygeal closure, thereby allowing more accurate clinical assessments and more appropriate treatment procedures. Children with cleft palate showed longer nasalization durations compared to those without the same. Thus, the degree of hypernasality in children with cleft palate may affect the temporal aspects of nasalization.

RESUMO

BACKGROUND: Decreased renal blood flow plays a vital role in the etiology of acute kidney injury (AKI). In this study, we aim to investigate the role of renal regional oxygen saturation (rSO2 ) reductions in predicting AKI in the first 24 h of life. METHODS: One hundred premature babies with a gestational age of ≤32 weeks were included. Renal and cerebral rSO2 s were monitored for 24 h by near-infrared spectroscopy. Infants were followed up for the first 7 days for the diagnosis of AKI. RESULTS: Infants' median gestational age was 29 (23-32) weeks, and their birthweight was 1,192 ± 355 g. It was found that the renal rSO2 values were lower in the first 24 h of life in patients who developed AKI, and this decrease was statistically significant in the first 6 h of life. CONCLUSIONS: The low renal rSO2 values in the early hours of life in premature babies may have a role in predicting AKI.

RESUMO

OBJECTIVE: Respiratory syncytial virus (RSV) is one of the most prevalent causes of lower respiratory tract infection (LRTI). The primary objective of this study is to provide the risk modelling of confirmed RSV infection in children who were born preterm at 29 to 35 weeks of gestational age and presented with LRTI. STUDY DESIGN: This prospective, multicenter study was performed between October 2015 and March 2017. Premature infants born with gestational age between 29 and 35 weeks that were ≤2 years of age at the beginning of the RSV season and admitted to the hospital with clinical findings of LRTI during the season were included. RSV-positive and -negative infants were compared in terms of demographic features, risk factors, and requirement of hospitalization. RESULTS: RSV positive group was lower than RSV negative group and ratio of ≤3 months age at admission was significant higher in RSV (+) group. RSV-positive infants were found to be significantly born during or 3 months prior to RSV season. The rate and duration of hospitalization and need for mechanical ventilation were significantly higher in RSV positive infants. The rate and duration of hospitalization in RSV positive patients was related to the chronological age. CONCLUSION: This study showed that preterm infants with RSV-associated LRTI significantly needed more hospitalization, intensive care admission, and mechanical ventilation. In addition need of hospitalization and duration of hospitalization were significant higher in ≤3 months of age. Therefore, we suggest the importance of palivizumab prophylaxis in infants ≤ 3 months chronological age, especially during the RSV season.

RESUMO

Importance: The benefits of surfactant administration via a thin catheter (minimally invasive surfactant therapy [MIST]) in preterm infants with respiratory distress syndrome are uncertain. Objective: To examine the effect of selective application of MIST at a low fraction of inspired oxygen threshold on survival without bronchopulmonary dysplasia (BPD). Design, Setting, and Participants: Randomized clinical trial including 485 preterm infants with a gestational age of 25 to 28 weeks who were supported with continuous positive airway pressure (CPAP) and required a fraction of inspired oxygen of 0.30 or greater within 6 hours of birth. The trial was conducted at 33 tertiary-level neonatal intensive care units around the world, with blinding of the clinicians and outcome assessors. Enrollment took place between December 16, 2011, and March 26, 2020; follow-up was completed on December 2, 2020. Interventions: Infants were randomized to the MIST group (n = 241) and received exogenous surfactant (200 mg/kg of poractant alfa) via a thin catheter or to the control group (n = 244) and received a sham (control) treatment; CPAP was continued thereafter in both groups unless specified intubation criteria were met. Main Outcomes and Measures: The primary outcome was the composite of death or physiological BPD assessed at 36 weeks' postmenstrual age. The components of the primary outcome (death prior to 36 weeks' postmenstrual age and BPD at 36 weeks' postmenstrual age) also were considered separately. Results: Among the 485 infants randomized (median gestational age, 27.3 weeks; 241 [49.7%] female), all completed follow-up. Death or BPD occurred in 105 infants (43.6%) in the MIST group and 121 (49.6%) in the control group (risk difference [RD], -6.3% [95% CI, -14.2% to 1.6%]; relative risk [RR], 0.87 [95% CI, 0.74 to 1.03]; P = .10). Incidence of death before 36 weeks' postmenstrual age did not differ significantly between groups (24 [10.0%] in MIST vs 19 [7.8%] in control; RD, 2.1% [95% CI, -3.6% to 7.8%]; RR, 1.27 [95% CI, 0.63 to 2.57]; P = .51), but incidence of BPD in survivors to 36 weeks' postmenstrual age was lower in the MIST group (81/217 [37.3%] vs 102/225 [45.3%] in the control group; RD, -7.8% [95% CI, -14.9% to -0.7%]; RR, 0.83 [95% CI, 0.70 to 0.98]; P = .03). Serious adverse events occurred in 10.3% of infants in the MIST group and 11.1% in the control group. Conclusions and Relevance: Among preterm infants with respiratory distress syndrome supported with CPAP, minimally invasive surfactant therapy compared with sham (control) treatment did not significantly reduce the incidence of the composite outcome of death or bronchopulmonary dysplasia at 36 weeks' postmenstrual age. However, given the statistical uncertainty reflected in the 95% CI, a clinically important effect cannot be excluded. Trial Registration: anzctr.org.au Identifier: ACTRN12611000916943.

RESUMO

BACKGROUND AND OBJECTIVE: Inner ear malformations (IEMs) are common in children with hearing loss. The different types of IEMs form a unique subgroup of cochlear implant (CI) candidates. We aimed to evaluate the auditory perception outcomes of CI in children with different types of IEMs and compare them with CI users without IEMs. METHODS: The study included 274 CI users with and without IEMs as two groups (n = 137, each). Both groups' chronological age at implantation and duration of CI usage was matched (± 8 months). All subjects were evaluated pre-operatively and post-operatively by the Ling's sound test and the auditory perception test battery, which includes the Meaningful Auditory Integration Scale (MAIS), closed-set Pattern Perception Test (PPT) and open-set Sentence Recognition Test (SRT). Besides, children with IEMs were assessed for language development. RESULTS: Progress in the IEMs' group differed according to the type of ear anomaly. CI users with enlarged vestibular aqueduct had the highest scores, while users with common cavity had the lowest. Children with IEMs performed well on the closed-set test while having difficulty with the open-set test. CONCLUSION: Cochlear implantation outcomes are favourable in IEMs' patients with a cochlear nerve visible on magnetic resonance imaging. Our results indicate that it is critical to take the anatomical differences into account during follow-up and rehabilitation programmes. Each CI user should be evaluated according to his or her individual needs.

RESUMO

IntroductionWe investigated the association between low 25-hydroxyvitamin D (25-OHD) levels and late-onset sepsis (LOS) in preterm infants (<37 weeks). Methods: Infants with culture-proven LOS were the study group, infants without LOS were the controls. 25-OHD levels were compared between these groups. Low vitamin D was defined as 25-OHD ≤15 ng/ml. Maternal 25-OHD levels were compared to their infant's level. Results: 108 infants were included. The study group was significantly younger (p = 0.02) with significantly lower 25-OHD levels (p < 0.001). Multivariable logistic regression analyses revealed that infants with low 25-OHD levels were 7.159 (95%CI: 1.402-36.553, p = 0.018) times more likely to develop LOS. A positive correlation was detected between maternal and neonatal 25-OHD levels for both study and control groups (r = 0.425, p = 0.009; r = 0.739, p < 0.001, respectively). Conclusions: Low 25-OHD levels are associated with an increased risk of developing LOS development in preterm infants.

RESUMO

OBJECTIVE: To determine audiological outcomes of children who use a cochlear implant (CI) in one ear and an auditory brainstem implant (ABI) in the contralateral ear. DESIGN: Retrospective case review. SETTING: Tertiary referral hospital. PARTICIPANTS: Twelve children followed with CI and contralateral auditory brainstem implant (ABI) by Hacettepe University Department of Otorhinolaryngology and Audiology in Turkey. All children were diagnosed with different inner ear malformations with cochlear nerve aplasia/hypoplasia. CI was planned in the ear with better sound detection during behavioural testing with inserted ear phones and with better CN as seen on MRI. Due to the limited auditory and speech progress with the cochlear implant, ABI was performed on the contralateral ear in all subjects. MAIN OUTCOME MEASURES: Audiological performance and auditory perception skills of children with cochlear nerve deficiency (CND) who use bimodal electrical stimulation with CI and contralateral ABI. RESULTS: Mean age of the subjects was 84.00 ± 33.94 months. Age at CI surgery and ABI surgery was 25.00 ± 10.98 months and 41.50 ± 16.14 months, respectively. However, hearing thresholds only with CI and only with ABI did not reveal significant difference, and auditory perception scores improved with bimodal stimulation. The MAIS scores were significantly improved from unilateral CI to bimodal stimulation (P = .002). Pattern perception and word recognition scores were significantly higher with the bimodal condition when compared to CI only and ABI only conditions. CONCLUSION: Children with CND showed better performance with CI and contralateral ABI combined. Depending on the audiological and radiological results, bimodal stimulation should be advised for children with CND.

RESUMO

Introduction: This study aimed to determine the association between serum mannose-binding lectin (MBL) levels, gene polymorphisms and late-onset sepsis (LOS) in preterm infants. Methods: Infants with <37 gestational weeks were categorized into two groups according to the presence of LOS during their hospitalization. An MBL level <700 ng/ml was defined as deficiency, <400 ng/ml as severe deficiency. Codon 54 and 57 polymorphisms of MBL2 gene were analyzed. Results: Overall, 153 preterm infants were included. MBL deficiency was found to be more common in the LOS group (p = 0.02). The rate of Gram-negative sepsis was higher in MBL2 variant-type (p = 0.01). In the logistic regression analysis, MBL levels <700 ng/ml were found to have a significant effect on LOS development (odds ratio: 2.692, 95% confidence interval 1.196-5.8, p = 0.02). Conclusions: MBL deficiency is an important risk factor for the development of LOS. Furthermore, there is an association between MBL2 gene polymorphism and Gram-negative sepsis.

RESUMO

Micafungin is recommended especially in patients with liver and kidney failure and in the presence of other side effects due to antifungals apart from its known priority indications such as invasive candidiasis. The aim of this study was to evaluate the children who have received micafungin treatment. In the study, 125 children who were hospitalized in the pediatric wards and intensive care units of our hospital and had used micafungin between November 2016 and January 2019 were analyzed retrospectively. Clinical data, micafungin indication, blood values on the first and fourth days of the treatment, side effects of the drug and efficacy were evaluated. Sixty percent (75/125) of the patients were male and the mean age of all the patients were 58 ± 67 (0-215, 30) months. Approximately half of the cases (48%) had malignancy and 13% of them were premature. Sixty-two percent (n= 37) of the malignencies were hematological (27 acute lymphocytic leukemia, nine acute myeloid leukemia, one myelodysplastic syndrome) and 38% (n= 23) were oncological (six neuroblastoma, four Hodgkin lymphoma, two Non-Hodgkin's lymphoma, five sarcomas, one hepatoblastoma, five others) malignencies. The major cause of hospitalization was sepsis (53%). The patients had several risk factors like immunosuppressive therapy (n= 68, 54%), neutropenia (n= 61, 49%), central venous catheter (n= 102, 82%), nasogastric tube (n= 63, 50%), endotracheal intubation tube (n= 49, 39%), urinary catheter (n= 14, 11%) and total parenteral nutrition (n= 81, 65%). Thirteen percent (n= 16) of the cases were post-operative patients. Candida species were cultivated in 97 clinical specimens (blood, endotracheal aspirate, sputum, urine, etc.) among 23 (18%) of the patients. Thirteen (10%) of the patients had candidemia and 62% of them were non-albicans strains. In all candidemias, strains were echinocandin susceptible, and blood cultures were negative within four days. When all the patients (n= 125) were evaluated, a significant decrease in C-reactive protein, an increase in sodium, and a decrease in alanine aminotransferase were observed on the fourth day of micafungin treatment (p<0.05). A total of 39 (31%) patients underwent various antifungal treatments for median seven (1-60) days prior to micafungin treatment. Fourteen (36%) of these 39 patients, had elevated liver function tests (LFT), 10 (26%) of them had hypokalemia, and five (13%) of them had elevated renal function tests. Ten (26%) patients had antifungal-induced hypokalemia previously; and potassium levels were normalized after micafungin treatment (p= 0.0001). The patients for which micafungin treatment was chosen due to elevated liver function tests (n= 47, 38%), whether the antifungalinduced or not; alanine aminotransferase and aspartate aminotransferase levels were decreased after micafungin treatment (p= 0.0001 and p= 0.0001, respectively). Nineteen (15%) of the patients have died within the first 30 days of micafungin treatment and one of them had candidemia. No micafungin treatment related significant side effects were observed in any of the patients. Our study showed that micafungin could be a safe and effective option in pediatric cases including newborns with high liver and kidney function tests.

RESUMO

OBJECTIVE: To investigate the effects of maternal preeclampsia on inflammatory cytokines and neonatal outcomes in premature infants. METHODS: The study included preterm infants born at gestational age ≤32 weeks in a tertiary university hospital between January 2016 and January 2017. The study group consisted of infants born from mothers with preeclampsia (Group-1), and the control group consisted of infants born from normotensive mothers (Group-2). Demographic characteristics and clinical outcomes of the infants were recorded. IL-6, IL-8, IL-10, and TNF-α cytokine levels were measured from umbilical cord blood samples. RESULTS: A total of 108 infants were included in the study, of which 34 were in the Group-1 and 74 in the Group-2. Gestational ages (29 vs 30 weeks) of the infants in both groups were similar. There was no significant difference between the cytokine levels of infants with and without preeclampsia. The rate of small for gestational age, retinopathy of prematurity, intraventricular hemorrhage, necrotizing enterocolitis, neutropenia, and thrombocytopenia were significantly higher at the infants with preeclampsia. CONCLUSION: Maternal preeclampsia leads to an increase at the neonatal morbidities in premature infants without causing a significant alteration at the cytokine levels in cord blood.

RESUMO

BACKGROUND: Parenteral nutrition (PN) has been widely used in preterm infants. The lipid solutions used for PN, however, are associated with oxidative stress and morbidity. The aim of this study was to compare the effectiveness of a new-generation lipid emulsion (SMOFLipid) and olive-oil based lipid emulsion for prevention of PN-associated oxidative damage. METHODS: Preterm infants < 32 weeks of gestational age were included in this prospective randomized study. All infants were randomized to SMOFlipid or olive-oil based lipid emulsion (ClinOleic). Lipid peroxidation products were evaluated in all infants. In addition, total antioxidant capacity (TAC), and both pro- and anti-inflammatory cytokines were studied at days 0, 7 and 14. RESULTS: A total of 89 infants (SMOFlipid, n = 42; ClinOleic, n = 47) were enrolled. TAC was higher in the SMOFlipid group compared with the ClinOleic group at all time points, and the difference on day 7 was statistically significant. Although the anti-inflammatory cytokine interleukin-10 was higher in the SMOFlipid group, this difference was not significant. Bronchopulmonary dysplasia (BPD) was lower in the SMOFlipid group (14.1%) than in the ClinOleic group (31.2%), but this finding was non-significant p > 0.05. The rate of severe BPD was significantly lower in the SMOFlipid group. CONCLUSION: To our best of knowledge, this is the first study to suggest that SMOFlipid might decrease oxidative damage and oxidative-stress-associated morbidity compared with olive oil-based emulsion in preterm infants.

RESUMO

Invasive candidiasis is a common and serious infection in premature newborns. Preventing and treating fungal infections is very important to improve the prognosis of premature infants. Fluconazole and amphotericin B are used as the first choice in the treatment of invasive fungal infections of the newborns. In some cases, fluconazole and amphotericin B cannot be used due to nephrotoxicity, hepatotoxicity or resistant strains. Micafungin, which is among recently developed echinocandins, is the drug of choice in these cases. The use of micafungin in newborns is new and there is a limited experience about the effect of high dose usage in the central nervous system. The aim of this study was to evaluate the electronic files of patients who used micafungin for the treatment of culture-proven or possible invasive fungal infection during their hospital stay in the neonatal intensive care unit during a 24-month period (2016-2017) in the third-level intensive care unit. A total of 15 patients (10 premature and 5 term babies) were included in the study. The mean birth weight of the patients was 1732 ± 999 g and the mean gestational age was 32.2 ± 5.8 weeks. All patients had long-term intensive care and increased risk of invasive candidiasis infection. Central venous catheterization and multiple antibiotics usage were the most common risk factors in these patients. The other risk factors included intubation, total parenteral nutritional use and surgical procedure application. Candida species were isolated from the cultures of four patients. Candida species isolated from patients were Candida albicans, Candida glabrata, Candida catenulata, Candida parapsilosis. The mean time for onset of micafungin was 29.9 ± 16.6 days. Mean duration of micafungin therapy was 22.4 ± 11.2 days. Eight patients received amphotericin B, three patients received fluconazole therapy and four patients did not receive any antifungal therapy before the onset of micafungin. None of these patients had an abnormal kidney or liver function tests due to micafungin use. As a conclusion, high dose (10 mg/kg/day) micafungin is a safe and effective treatment choice both in the treatment of neonatal culture proven or probable invasive candida infections that were caused by refractory Candida strains, and in the case of nephrotoxicity and hepatotoxicity.

RESUMO

OBJECTIVE: To assess the short- and long-term effects of the adjustable fortification (ADJ) regimen on growth parameters in premature infants and to evaluate the amount of protein supplements given to reach the targeted blood urea nitrogen (BUN) levels. METHODS: In this retrospective study, preterm babies who were born at ≤32 weeks gestational age and fed with human milk, were evaluated in two groups. Infants in Group-I were fed only standard fortification (STD). Infants in Group-II were fed the ADJ regimen. The study was conducted between 2011 and 2016. RESULTS: There were 123 infants in the STD group and 119 in the ADJ group. The mean gestational age of the patients in Group-I was 29.7±1.8 weeks, and mean birth weight was 1266.1±347.1 g. The mean gestational age of the patients in Group-II was 29.5±1.9 weeks, and the mean birth weight was 1217.5±345.5 g. The daily increase in weight and weekly increase in HC were significantly higher in the ADJ group infants. Weight and HC of infants in the ADJ group were significantly higher at 40 weeks. At one year corrected age, weight, length, and HC measurements of both groups were similar. In Group-II, 63% of patients required additional protein supplementation up to 1.6 g/day to achieve the target BUN levels. CONCLUSION: A higher protein intake through the ADJ regimen improves the physical growth rate of premature infants in the NICU and after discharge. However, sometimes, the targeted growth and BUN values cannot be achieved despite the administration of protein at the recommended increased doses. Increasing protein supplementation up to 1.6 g/day is safe, feasible, and beneficial for these infants.

RESUMO

Background & Objective: Preterm infants need nutritional and medical requirements in accordance with the physiologic maturity at birth and maintaining optimal postnatal corporal and cerebral growth is one of the main targets of medical caregivers. However, only a few strategies exist to improve the outcomes of infants in a pathogen-rich and nutrient-poor neonatal intensive care unit environment. In this pilot study, we hypothesize that synbiotics may enhance brain growth, which is reflected indirectly by an increase in head circumference through several signalling molecules. Methods: A pilot study was conducted in preterm infants with a gestational age of ≤32 weeks and a birth weight of ≤1500 grams at neonatal intensive care unit of Uludag Univeristy Medical Faculty (NICU) for one-year period. Following the randomization of the infants, a prepared commercial synbiotic solution containing multi-combined probiotics and prebiotics was administered enterally to the study group. Results: The odds of a patient having a lower body weight and head circumference below the 10th percentile were significantly lower in the probiotic group (p=0.001, p=0.03, respectively). Moreover, the infants in the synbiotics group had a more optimal head circumference (between the 50th and 90th percentiles, p=0.001). Conclusions: Our results show that if we can maintain optimal gut microbiota, we might achieve better neuro-development via the beneficial effects of synbiotics on cytokines, neurotransmitters, and the cellular immunity of the nervous system. Further investigational models are needed to demonstrate the beneficial effects of synbiotics on the central nervous system.
