Objective To investigate the early neonatal outcomes of very-low-birth-weight (VLBW) infants discharged home from neonatal intensive care units (NICUs) in Turkey. Material and methods A prospective cohort study was performed between April 1, 2016 and April 30, 2017. The study included VLBW infants admitted to level III NICUs. Perinatal and neonatal data of all infants born with a birth weight of.1500 g were collected for infants who survived. Results Data from 69 NICUs were obtained. The mean birth weight and gestational age were 1137 +/- 245 g and 29 +/- 2.4 weeks, respectively. During the study period, 78\% of VLBW infants survived to discharge and 48\% of survived infants had no major neonatal morbidity. VLBW infants who survived were evaluated in terms of major morbidities: bronchopulmonary dysplasia was detected in 23.7\% of infants, necrotizing enterocolitis in 9.1\%, blood culture proven late-onset sepsis (LOS) in 21.1\%, blood culture negative LOS in 21.3\%, severe intraventricular hemorrhage in 5.4\% and severe retinopathy of prematurity in 11.1\%. Hemodynamically significant patent ductus arteriosus was diagnosed in 24.8\% of infants. Antenatal steroids were administered to 42.9\% of mothers. Conclusion The present investigation is the first multicenter study to include epidemiological information on VLBW infants in Turkey. Morbidity rate in VLBW infants is a serious concern and higher than those in developed countries. Implementation of oxygen therapy with appropriate monitoring, better antenatal and neonatal care and control of sepsis may reduce the prevalence of neonatal morbidities. Therefore, monitoring standards of neonatal care and implementing quality improvement projects across the country are essential for improving neonatal outcomes in Turkish NICUs.
Epidemiologic and clinical characteristics of neonates with late-onset COVID-19: 1-year data of Turkish Neonatal Society

The literature on neonates with SARS-CoV-2 is mainly concerned with perinatal cases, and scanty data are available about environmentally infected neonates. To fill knowledge gaps on the course and prognosis of neonatal cases, we analyzed 1-year data from the Turkish Neonatal Society in this prospective cohort study of neonates with postnatal transmission. Data from 44 neonatal intensive care units (NICUs), of neonates with positive RT-PCR results at days 5-28 of life, were extracted from the online registry system and analyzed. Of 176 cases, most were term infants with normal birth weight. Fever was the most common symptom (64.2\%), followed by feeding intolerance (25.6\%), and cough (21.6\%). The median length of hospitalization was 9 days, with approximately one quarter of infants receiving some type of ventilatory support. Myocarditis (5.7\%) was the most common complication during follow-up. Among the clinical findings, cough (odds ratio {[}OR]: 9.52, 95\% confidence interval {[}CI]: 4.17-21.71), tachypnea (OR: 26.5, 95\% CI: 9.59-73.19), and chest retractions (OR: 27.5, 95\% CI: 5.96-126.96) were associated with more severe clinical disease. Also, there were significant differences in the C-reactive protein level, prothrombin time (PT), partial thromboplastin time, international normalized ratio, and days in the NICU (p = 0.002, p = 0.012, p = 0.034, p = 0.008, and p < 0.001, respectively) between patients with mild-moderate and severe-critical presentations. A PT above 14 s was a significant predictor of severe/critical cases, with a sensitivity of 64\% and specificity of 73\%. Conclusions: Our data showed that late-onset COVID-19 infection in neonates who need hospitalization can be severe, showing associations with high rates of ventilatory support and myocarditis. Cough, tachypnea, and retractions on admission suggest a severe disease course.

R.-R.O.P. Study
Background To evaluate the prevalence, risk factors and treatment of retinopathy of prematurity (ROP) in Turkey and to establish screening criteria for this condition. Methods A prospective cohort study (TR-ROP) was performed between 1 April 2016 and 30 April 2017 in 69 neonatal intensive care units (NICUs). Infants with a birth weight (BW)=1500 g or gestational age (GA)<= 32 weeks and those with a BW> 1500 g or GA> 32 weeks with an unstable clinical course were included in the study. Predictors for the development of ROP were determined by logistic regression analyses. Results The TR-ROP study included 6115 infants: 4964 (81\%) with a GA <= 32 weeks and 1151 (19\%) with a GA>32 weeks. Overall, 27\% had any stage of ROP and 6.7\% had severe ROP. A lower BW, smaller GA, total days on oxygen, late-onset sepsis, frequency of red blood cell transfusions and relative weight gain were identified as independent risk factors for severe ROP in infants with a BW=1500 g. Of all infants, 414 needed treatment and 395 (95.4\%) of the treated infants had a BW <= 1500 g. Sixty-six (16\%) of the treated infants did not fulfil the Early Treatment for Retinopathy of Prematurity requirements for treatment. Conclusions Screening of infants with a GA <= 34 weeks or a BW<1700 g appears to be appropriate in Turkey. Monitoring standards of neonatal care and conducting quality improvement projects across the country are recommended to improve neonatal outcomes in Turkish NICUs.

Background: Healthcare-acquired infections (HAIs) in the neonatal period cause substantial morbidity, mortality, and healthcare costs. Our purpose was to determine the prevalence of HAIs, antimicrobial susceptibility of causative agents, and the adaptivity of the Centres for Disease Control and Prevention (CDC) criteria in neonatal HAI diagnosis. Methods: A HAI point prevalence survey was conducted in the neonatal intensive care units (NICUs) of 31 hospitals from different geographic regions in Turkey. Results: The Point HAI prevalence was 7.6\%. Ventilator-associated pneumonia (VAP) and central line-associated bloodstream infections (CLABSI) and late onset sepsis were predominant. The point prevalence of VAP was 2.1\%, and the point prevalence of CLABSI was 1.2\% in our study. The most common causative agents in HAIs were Gram-negative rods (43.0\%), and the most common agent was Klebsiella spp (24.6\%)
