ABSTRACT
Background: This study aimed to investigate the effectiveness of intranasal dexmedetomidine in reducing pain scores during retinopathy of prematurity (ROP) screening examinations in preterm infants. Methods: Infants born at ≤32 weeks of gestational age, undergoing routine ROP examinations in the neonatal intensive care unit, were included in the study and divided into two groups: the standard protocol group (n = 43) and the dexmedetomidine group (n = 56), over a 1-year period. Both groups received standard procedural preparation including swaddling, oral dextrose, and topical anesthesia with proparacaine. The dexmedetomidine group additionally received intranasal dexmedetomidine at a dose of 1â mcg/kg before the procedure. Pain scores (PIPP score), heart rate, respiratory rate, blood pressure, and oxygen saturation were compared at baseline, 1-min, and 5-min during the procedure. Results: There were no significant differences between the groups regarding descriptive and pre-procedure characteristics. In the dexmedetomidine group, the median (25-75p) PIPP score, heart rate, systolic blood pressure and mean (±SD) respiratory rate measured at the 1st minute of the procedure were significantly lower than those in the standard group [PIPP score 10 (8-13) vs. 14 (10-16), p < 0.001; heart rate 165 (153-176) beats/min vs. 182 (17-190) beats/min, p < 0.001; respiratory rate 60 (±7) breaths/min vs. 65(±9) breaths/min, p = 0.002; systolic blood pressure 78 (70-92) mmHg vs. 87 (78-96) mmHg, p = 0.024; respectively] whereas the saturation value was significantly higher (88% (81-95) vs. 84% (70-92), p = 0.036; respectively). By the 5th minute of the procedure, the median (25-75p) PIPP score [4 (2-6) vs. 6 (4-10), p < 0.001], heart rate [148 (143-166) beats/min vs. 162 (152-180) beats/min, p = 0.001] and respiratory rate [56 (54-58) breaths/min vs. 58 (54-62) breaths/min, p = 0.034] were significantly lower, and the saturation level was significantly higher [96% (94-97) vs. 93% (91-96), p = 0.003] in the dexmedetomidine group. Additionally, the frequency of adverse effects was significantly lower in the dexmedetomidine group compared to the standard protocol group (11% vs. 47%, p = 0.001). Conclusion: Administering intranasal dexmedetomidine before ROP screening examinations was associated with a decrease in pain scores among preterm infants. This suggests its potential as an effective and well-tolerated method for pain management during ROP screenings.
ABSTRACT
BACKGROUND: Perilipin 2 (PLIN2) is a protein that contributes to the formation and stability of lipid droplets. It has been associated with the development of several diseases, particularly related to glucose and lipid metabolism. In infants of diabetic mother (IDM), fetal hyperinsulinaemia leads to increased adipose tissue and macrosomia. The aim of this study was to investigate the relationship between PLIN2 levels and anthropometric measurements in the IDM and to investigate the relationship between PLIN2 levels and IGF-1, IGF-2 and leptin levels. METHODS: The study group consisted of IDMs, while the control group consisted of infants born to non-diabetic mother, matched for gestational week and gender. Cord blood samples were collected from all patients to determine PLIN2, IGF-1, IGF-2 and leptin levels. Anthropometric measurements were taken for all patients at birth. RESULTS: There were no differences between the groups in birth weight, birth length, head circumference and body mass index (BMI), but middle arm circumference, triceps, biceps, subscapular and suprailiac skinfold thickness were significantly higher in the IDM. While PLIN2, IGF-1, IGF-2 and leptin levels were similar between groups, there was a strong correlation between PLIN2 levels and IGF-2 and leptin levels. CONCLUSIONS: Even if IDMs were not macrosomic, the presence of high subcutaneous adipose tissue was not associated with PLIN2.
ABSTRACT
BACKGROUND: This study aimed to examine early clinical and laboratory findings in infants born to mothers who had organ transplants and received immunosuppressive treatment. METHODS: Between 2016 and 2023, the study examined infants of mothers who underwent organ transplantation and were receiving immunosuppressive treatment, and followed at the Department of Neonatology at Akdeniz University. Demographic, clinical, and laboratory characteristics of mothers and infants were recorded. On the first day of life, complete blood count values were examined, as well as potassium levels on the first, third, and seventh days, and creatinine levels on the third and seventh days. The tacrolimus blood level was calculated by taking the average of the tacrolimus blood values of the mother measured during the pregnancy. The infants were evaluated for any potential morbidities caused by intrauterine immunosuppressive drug exposure. RESULTS: The study included 21 mothers (some with multiple pregnancies) and 27 infants. According to the findings of this study, 74% of these infants were born premature, 67% had low birth weight, and all were delivered via cesarean section. Prematurity was associated with the morbidities found in the infants. In the early period, lymphopenia was detected in 37%, neutropenia in 25.9%, thrombocytopenia in 11.1%, hyperkalemia in 18.5%, and creatinine elevation in 7.4%, all of which returned to normal within a few days. There was no significant relationship between maternal tacrolimus blood levels and infant potassium and creatinine levels. CONCLUSION: Apart from an increased risk of prematurity, low birth weight, and cesarean delivery, no effects were observed in these infants during the early period. However, long-term follow-up is necessary to monitor for any potential morbidities.

Objetivo. Investigar la frecuencia de la enterocolitis necrosante (ECN) en prematuros y evaluar los factores de riesgo asociados con su aparición y progresión a perforación intestinal.Métodos. Cohorte retrospectiva de prematuros hospitalizados entre 2015 y 2018. Las características perinatales, clínicas, nutricionales y de laboratorio se analizaron con SPSS-23, y los factores de riesgo mediante una regresión logística.Resultados. En 1428 neonatos, la tasa de ECN fue del 18,28 %. La concepción por reproducción asistida, la cesárea y los corticoesteroides posnatales se asociaron con ECN (OR: 4,056; IC del 95 %: 2,810-5,854; OR: 1,961; IC del 95 %: 1,321-2,910; OR: 6,422; IC del 95 %: 4,327-9,530). El momento de la primera alimentación enteral se asoció con ECN, pero no con perforación intestinal (p < 0,001; p = 0,604). De 261 pacientes con ECN, 47 (18 %) tuvieron perforación intestinal. El momento de la primera alimentación enteral y el ductus persistente con repercusión hemodinámica fueron factores predisponentes para ECN, y el puntaje de Apgar bajo al minuto 5 para perforación intestinal. (OR: 6,515; IC del 95 %: 5,011-8,470; OR: 4,715; IC del 95 %: 2,717-8,183; OR: 2,748; IC del 95 %: 1,100-6,866). La mortalidad fue del 9 %. La ECN aumentó el riesgo de mortalidad 2,192 veces (IC del 95 %: 1,469-3,271); en perforación intestinal, el riesgo aumentó 11,527 veces (IC del 95 %: 6,293-21,115).Conclusión. El conducto arterial persistente y el retraso en la primera nutrición enteral fueron factores predisponentes para ECN, y el puntaje de Apgar bajo al minuto 5 para perforación intestinal.
Aim. To investigate NEC frequency in premature infants and assess risk factors associated with disease-onset and progression to intestinal perforation.Methods. Retrospective cohort in preterm neonates hospitalized between 2015 and 2018. Perinatal characteristics, clinical features, nutritional data and laboratory outcome were analyzed using SPSS-23 statistical package. Logistic regression was performed to analyze associated risk factors.Results. In 1428 neonates, the rate of developing NEC was 18.28 %. Conception with assisted reproductive technology, cesearean section and postnatal-steroids were associated with NEC (OR: 4.056, 95 % CI: 2.810-5.854, OR: 1.961, 95 % CI: 1.321-2.910, OR: 6.422; 95 % CI: 4.327-9.530).Timing of first enteral feeding was associated to developing NEC, but not to intestinal perforation (p < 0.001, p = 0.604). Forty-seven of 261 NEC patients (18 %) have developed intestinal perforation. Antenatal steroids showed to reduce severe consequences (p = 0.001). Timing of first enteral feeding and hemodynamically significant PDA were predisposing factors for NEC and low 5-minutes Apgar score for intestinal perforation. (OR: 6.515; 95 % CI: 5.011-8.470; OR: 4.715; 95 % CI: 2.717-8.183; OR: 2.748; 95 % CI: 1.100-6.866).Mortality was 9 %. Developing NEC increased risk of mortality by 2.192 times (95 % CI: 1.469-3.271); in intestinal perforation, mortality risk increased to 11.527 (95 % CI: 6.293-21.115).Conclusion. NEC frequency was 18.28 %. Intestinal perforation occurred in 18 % of NEC patients. PDA and delay in first enteral nutrition were predisposing factors for acquiring NEC and low 5-minutes Apgar scores for intestinal perforation
