Öğe Differences in Possible Risk Factors, Treatment Strategies, and Outcomes of Neonatal Pneumothorax in Preterm and Term Infants(Aves, 2024) Tandircioglu, Umit Ayse; Koral, Umran; Guzoglu, Nilufer; Alan, Serdar; Aliefendioglu, DidemObjective: The study aimed to compare the risk factors, treatment strategies, and early outcomes of symptomatic neonatal pneumothorax (NP) between preterm and term newborns. Materials and Methods: This retrospective cross-sectional study was conducted in a neonatal intensive care unit between 2015 and 2022, consisting of hospitalized neonates with symptomatic NP. The cases were divided into three groups according to their gestational ages: <34(0/7 )(group 1), 34(0/7)-36(6/7) (group 2), and >= 37(0/7) weeks (group 3). Risk factors, treatment strategies, and mortality rates of the study groups were compared using Kruskal-Wallis analysis. Results: Fifty-nine infants with a diagnosis of symptomatic NP were included in the study. The number of participants was as follows: 25 (42.3%) in group 1, 18 (30.5%) in group 2, and 16 (27.1%) in group 3. The need of delivery room (DR) resuscitation was significantly higher in group 1 (40%, P = .003). The surfactant administration rate was significantly higher in group 1 when compared to group 2 and group 3 (68% vs. 22% and 19%, respectively), P < .001. Similarly, the invasive mechanical ventilation percentage was significantly higher in group 1 than group 2 and group 3, P = .014. However, compared to group 3 (63%), the percentage of chest drain insertion (CDI) need was significantly higher in group 1 (96%) and group 2 (89%) (P = .014). Conclusion: Exposure to DR resuscitation and the need for surfactant are the most common risk factors for NP in preterm infants. Although oxygen and/or needle aspiration treatments are less invasive in symptomatic NP, the improvement rate without CDI is very low in preterm infants born before 34 weeks of gestational age.Öğe Direct Effect of Caffeine on Diaphragmatic Muscles in Preterm Babies Through Ultrasonographic Examination(Aves, 2024) Kayki, Gozdem; Celik, Hasan Tolga; Ayaz, Ercan; Tandircioglu, Umit Ayse; Oguz, Berna; Yigit, Sule; Yurdakok, MuratObjective: Caffeine is frequently used for the treatment of apnea in preterm babies. Its mechanism of action includes not only antagonism of adenosine receptors on central nervous system but also an increase in electrical activity of the diaphragm. Caffeine's direct effect on diaphragm was investigated via electromyography, but ultrasound has not been used to show visible changes in muscles after the treatment before. Therefore, we aimed to assess the effect of caffeine on diaphragmatic function through ultrasonographic examination. Materials and Methods: It was a prospective observational study. Fifty-six participants receiving nasal continuous positive airway pressure with less than or equal to 32 weeks' gestational age born were enrolled. Diaphragmatic thickness, amplitude of excursion, and velocity of movement were measured before and within 5 minutes after caffeine loading dose and compared to each other. The protocol was registered with ClinicalTrials.gov Identifier NCT04483492. Results: Diaphragmatic thicknesses and diaphragmatic velocity of movement did not differ after the treatment. However, amplitude of excursion of the diaphragm was found significantly higher after caffeine loading dose (8.7 mm, 10mm, respectively, P < .05). Conclusion: Diaphragm excursion increased after caffeine treatment in preterm babies, and this finding was potentially supported the direct effect of the caffeine on diaphragm. Another important finding of this study is that it reinforces the utility of ultrasonography in assessing diaphragmatic function in preterm infants.Öğe How reliable is the statistical evaluation using the 'mean' in an abnormally distributed dataset?(Springer Science and Business Media Deutschland GmbH, 2024) Tandircioglu, Umit Ayse; Ates, Can; Alan, Serdar[No abstract available]Öğe Influence of Intensive Care Unit Enlightenment on Premature Infants on Functional Brain Maturation Assessed by Amplitude-Integrated Electroencephalograph(Thieme Medical Publ Inc, 2021) Tandircioglu, Umit Ayse; Guzoglu, Nilufer; Gucuyener, Kivilcim; Aliefendioglu, DidemObjective Amplitude-integrated electroencephalograph (aEEG) presents a valuable tool for functional brain maturation of preterm infants. However, the effect of enlightenment on functional brain maturation of premature infants has not been investigated. We aimed to do this with aEEG. Study Design A total of 32 infants, 30 to 35 gestational weeks, were involved in the study. They were randomly distributed into three groups in which different lighting protocols were applied. In group 1, the infants' incubators were covered for 24 hours. In group 2, the infants' incubators were open for 24 hours. In group 3, the infants' incubators were covered for 12 hours and open for another 12 hours. The infants are evaluated with aEEG recordings done on the 3rd (first measurement) and 10th days (second measurement) along with the Burdjalov scoring. Analysis of aEEG recordings was performed, based on sleep-wake cycles (SWCs), upper and lower margin amplitudes, narrowband and broadband of SWC, and bandwidth of SWC. Results At first, the narrowband lower amplitudes in group 1 were higher than those of the other groups (p = 0.042), but the difference was not significant in the second measurement (p = 0.110). The Burdjalov scores were higher in group 1 and group 3 on 10th day, though not statistically significant (p = 0.871). When the infants were reevaluated according to the gestational weeks, the Burdjalov scores of the two groups less than 34 weeks (30-31 and 32-33 weeks) were similar, whereas 34 to 35 weeks were higher when compared with those of the two groups. Conclusion The difference observed between groups in terms of narrowband lower amplitude in the first measurement may reflect the effect of intrauterine environment rather than enlightenment at the same gestational age because it was made on the third day. However, the fact that all groups have similar results on day 10 suggests that other factors in the intensive care setting may diminish the effect of enlightenment. Burdjalov scores are associated with maturation, and high scores found in the 34- to 35-week group suggest that the 34-week maturation might be a threshold for SWC and development in our group sample.Öğe Management of hyperbilirubinemia in preterm infants in Turkey(Tubitak Scientific & Technical Research Council Turkey, 2016) Guzoglu, Nilufer; Tandircioglu, Umit Ayse; Aliefendioglu, DidemBackground/aim: Prematurity is a significant risk factor for developing unconjugated hyperbilirubinemia. This study investigated the current approach to managing hyperbilirubinemia in preterm newborns in Turkey. Materials and methods: A study-specific questionnaire on the management of jaundice in preterm infants was sent to 100 level III neonatal intensive care units in Turkey. Results: Responses were obtained from 84 centers from all regions of Turkey. Of the centers, 75.3% used the Turkish Neonatology Society guidelines for deciding to start phototherapy, and 24.7% used different guidelines. The monitoring of bilirubin varied among the participants. Of the participants, 53.6% believed that prophylactic phototherapy was necessary if the infant's birth weight was below 1000 g. The participants reported 6 cases of kernicterus in preterm infants in recent years. Conclusion: There is no single standard approach for managing neonatal hyperbilirubinemia in preterm infants in Turkey. Prophylactic phototherapy for extremely low birth-weight infants might be added to the guidelines for Turkey.Öğe Prospective Evaluation of the Correlation of Lung Ultrasonography Score and Blood Gas Parameters in Neonates With Respiratory Distress(Springernature, 2023) Tandircioglu, Umit Ayse; Melekoglu, Nuriye AsliIntroduction Lung ultrasonography (LUS) has become frequently used in neonatal intensive care units (NICU) because it is diagnostic, useful, harmless, radiation-free, and practical for bedside use due to its portability.Objective This study aimed to evaluate the association between lung ultrasound (LUS) scores and diagnoses of neonates hospitalized for respiratory distress and determine the value of the combined use of laboratory and imaging methods in patient evaluation by looking at the correlation between blood gas parameters and LUS score. Materials and methods Between March and July 2022, a total of 55 patients who were born term or premature and admitted due to respiratory distress in the NICU of Malatya Training and Research Hospital were included in the study. In this observational, prospective study, demographic information such as birth weights, gestational weeks, mode of delivery, Apgar scores, blood gas sample results, LUS results and scores, ventilation types, and discharge time were recorded during hospitalization in our unit. According to the newborns' clinical, laboratory, and radiologic evaluations, the diagnoses of respiratory distress syndrome (RDS), transient tachypnea of the newborn (TTN), or congenital pneumonia were made, and the relationship between the diagnoses and LUS scores was evaluated. The pH value and PCO2 value in the venous blood gas obtained on the day of LUS were recorded. Correlation analysis was performed between the LUS score and pH value, LUS score and PCO2 value.Results Twenty-seven newborns were diagnosed with TTN, 18 with RDS, and 10 with congenital pneumonia. There was a statistical difference between LUS scores and diagnoses (p<0.001). According to Spearman correlation analysis, a significant negative moderate correlation was found between LUS scores and venous blood gas pH value (p<0.001, r:-0.49). There was also a significant positive low, moderate correlation with venous blood gas PCO2 value (p<0.001, r:0.36).Conclusion This study demonstrates that LUS scoring has a role in determining the severity of disease and making diagnoses in patients hospitalized for respiratory distress. When LUS is widely used, it will be informative about the severity and prognosis of the disease, together with laboratory evaluation.Öğe Widespread eruption after blood transfusion during phototherapy in a newborn(Wiley, 2024) Tandircioglu, Umit Ayse; Alan, Serdar[Abstract No tAvailable]
