Abstract
OBJECTIVE Bronchopulmonary dysplasia (BPD) is a leading cause of morbidity and mortality in neonatal intensive care units. Our aim was to evaluate association between packed red blood cell transfusion and the development of BPD in very preterm infants. STUDY DESIGN This retrospective study of very preterm infants (mean gestational age: 27.1 ± 2.4 weeks, birth weight: 970 ± 271 g) was conducted at Biruni University (Turkey) between July 2016 and December 2020. RESULTS BPD developed in 107 of the 246 enrolled neonates, including 47 (43.9%), 27 (25.3%), and 33 (30.8%) diagnosed with mild, moderate, and severe BPD, respectively. A total of 728 transfusions were administered. The increased number (4 transfusions [2-7] vs. 1 [1-3], p = 0.001) and volume of transfusions (75 mL/kg volume [40-130] vs. 20 [15-43], p = 0.001) were significantly higher in infants with BPD compared to those without BPD. The transfusion volume cut-off for the prediction of BPD by receiver operating characteristic curve analysis was 42 mL/kg (sensitivity 73.6%; specificity 75%; area under the receiver-operating characteristic curve: 0.82). In multivariate analysis, multiple transfusions and larger transfusion volume were independent risk factors for moderate-severe BPD. CONCLUSION The increased number and volume of transfusions were associated with BPD in very preterm infants. A packed red blood cell transfusion volume ≥42 mL/kg was a statistically significant predictor of the development of BPD at a postmenstrual age of 36 weeks. KEY POINTS · Transfusions were found to be an important risk factor for BPD development in very premature infants.. · Number and volume of transfusion were associated with the severity of BPD.. · Optimal cut point volume of transfusion for prediction of BPD was 42 mL/kg body weight..

Epidemiology, risk factors, clinical presentation and complications of late-onset neonatal sepsis among preterm neonates in Cyprus: a prospective case-control study. BMC Pediatr 2024; 24:50. [PMID: 38229029 DOI: 10.1186/s12887-023-04359-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2022] [Accepted: 10/12/2023] [Indexed: 01/18/2024] Open
Abstract
BACKGROUND Late-onset neonatal sepsis (LOS) is common in preterm neonates, with increasing incidence in recent years. In the present study, we examined the epidemiology, clinical presentation, and complications of LOS in Cyprus and quantified possible risk factors for the development of this condition. METHODS The study subjects were preterm neonates admitted in the Neonatal Intensive Care Unit (NICU) of Archbishop Makarios III Hospital, the only neonatal tertiary centre in Cyprus. A prospective, case-control study was designed, and carried out between April 2017-October 2018. Depending on blood culture results, preterm neonates were classified as "Confirmed LOS": positive blood culture - microorganism isolated and LOS symptoms, "Unconfirmed LOS": negative blood culture and LOS symptoms, and "Controls" group: negative blood culture and absence of LOS symptoms. Comparisons between the 3 groups were performed and the associations between demographic, clinical and treatment characteristics with the likelihood of LOS were assessed using univariate and multivariate logistic regression. RESULTS A total of 350 preterm neonates were included in the study and the incidence of LOS was 41.1%. 79 (22.6%) and 65 (18.6%) neonates were classified as "Confirmed LOS", and "unconfirmed LOS" cases respectively while 206 (58.9%) served as controls. The rate of confirmed LOS ranged from 12.2% in moderate to late preterm neonates to 78.6% in extremely preterm neonates. In the multivariate model, we demonstrated an independent association between LOS and duration of hospitalization (OR: 1.06, 95%CI: 1.01-1.10), duration of ventilation (OR: 1.23, 95%CI: 1.07-1.43) and necrotising enterocolitis (OR: 3.41, 95%CI: 1.13-10.25). CONCLUSIONS The present study highlights the epidemiology of LOS in preterm neonates in Cyprus and its association with the duration of ventilation and hospitalization as well as with necrotizing enterocolitis. Establishment of protocols for the prevention of nosocomial infections during hospitalization in the NICUs and mechanical ventilation of preterm neonates is recommended.

Abstract
Different CE techniques have been used to analyze erythropoietin. These techniques have been shown to be effective in differentiating and quantifying erythropoietin isoforms, including natural and recombinant origins. This review provides a comprehensive overview of various capillary electrophoresis-based techniques used for the analysis of erythropoietin isoforms. The importance of erythropoietin in clinical practice and the necessity for the accurate analysis of its isoforms are first discussed. Various techniques that have been used for erythropoietin isoform analysis are then described. The main body of the review focuses on the different capillary electrophoresis-based methods that have been developed for erythropoietin isoform analysis, including capillary zone electrophoresis and capillary isoelectric focusing. The advantages and drawbacks of each method as well as their applications are discussed. Suggestions into the future directions of the area are also described.

Abstract
BACKGROUND Blood centers play a critical role in supporting neonatal and pediatric transfusions. We aim to study the variation in pediatric/neonatal transfusion policies and practices for blood centers in India. STUDY DESIGN AND METHODS This is a survey-based (45 question) cross-sectional assessment of blood centers in India supporting pediatric/neonatal transfusions. RESULTS One hundred three centers responded to the survey (response rate 51.2%; 103/201). As a part of pretransfusion testing, use of "microtainers" was reported by 58.4% (59/101) centers and only 57.4% (58/101) centers provide antibody screening. In case of absence of maternal sample, type O negative blood is most commonly used (48.5%; 49/101), and in case of ABO incompatibility, 68.3% (69/101) use units compatible with both mother and newborn. Leukoreduced RBCs are provided by 89% (90/101) centers and irradiated products are provided by 48.5% (49/101). 82% (83/101) of centers reported not receiving requests for CMV negative units considering the high incidence of CMV-seropositivity in donors. Fresh units are defined as <7 days old by 44.5% (45/101) and <5 days old by 31.6% (32/101) centers. 97% centers reported SAGM suspended RBCs in inventory but only 67.3% (68/101) use them for top-up transfusions to neonates. Overall >80% centers use the buffy-coat method for platelet concentrates preparation. Volume-based (ml/kg) aliquots preparation is done by 88% (89/101), mainly using the sterile connecting device (84.6%; 83/98). CONCLUSION This survey shows heterogeneity and lack of standardization in practices across blood centers in India and highlights the need for more studies to establish best practices for this vulnerable age group.

Transfusion prevention using erythropoietin, parenteral sucrose iron, and fewer phlebotomies in infants born at ≤30 weeks gestation at a high altitude center: a 10-year experience. J Perinatol 2021; 41:1403-1411. [PMID: 33568772 DOI: 10.1038/s41372-021-00945-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2020] [Revised: 11/11/2020] [Accepted: 01/19/2021] [Indexed: 01/31/2023]
Abstract
INTRODUCTION Red blood cell transfusions in infants born at ≤30 weeks gestation are frequent. Erythropoietin therapy reduces transfusions. An increase in hematocrit is an adaptive response at high altitudes but a guaranteed source of iron is necessary for adequate erythropoiesis. METHODS A retrospective cohort study was done to compare red blood cell transfusion practices of the 2019 EpicLatino (EPIC) Latin America network database with a single unit at 2650 m above sea level (LOCAL). The data from LOCAL for three time periods were compared over 10 years based on changes in erythropoietin dose and fewer phlebotomies. The number of cases that received transfusions and the total number of transfusions required were compared. Adjustments were made for known risk factors using a multivariate regression analysis. RESULTS Two hundred and twenty-one cases in LOCAL and 382 cases from EPIC were included. Overall basic demographic characteristics were similar. In EPIC a significantly higher rate of infection (28% vs. 15%) and outborn (10% vs. 1%) was found, but less necrotizing enterocolitis (9% vs. 15%) and use of prenatal steroids (62% vs. 93%) than LOCAL (p < 0.05). EPIC patients received more transfusions (2.6 ± 3 vs. 0.6 ± 1 times) than LOCAL (p < 0.001) and received them significantly more frequently (61% vs. 25%). Within the LOCAL time periods, no statistically significant differences were found other than the need for transfusions (1st 32%, 2nd 28%, 3rd 9%, p = 0.005) and the average number of transfusions (1st 0.8 ± 1.6, 2nd 0.7 ± 1.3, 3rd 0.1 ± 0.3, p = 0.004). These differences remained significant after multivariate regression analysis and adjusting for risk variables. CONCLUSION The combination of erythropoietin, parenteral sucrose iron, fewer phlebotomies during the first 72 h, and delayed umbilical cord clamping seem to reduce red blood cell transfusion needs. This can be extremely important in high altitude units where higher hematocrit is desirable but may also be valuable at sea level.
