Blood transfusion and neonate

INTRODUCTION: Non-immune hydrops fetalis (NIHF) is the most frequent etiology of hydrops fetalis (HF), accounting for around 95% of cases. It associates high perinatal mortality and morbidity rates. The aim of the study was firstly, to investigate etiology, prenatal management, and perinatal outcome in a large single center series of HF; secondly, to identify prenatal prognostic factors with impact on perinatal outcome. MATERIAL AND METHODS: Observational retrospective study of 80 HF diagnosed or referred to a single tertiary center between 2012 and 2021...

OBJECTIVE: To assess concordance between umbilical cord blood (UCB) and neonatal blood (NB) laboratory test results at birth. STUDY DESIGN: This retrospective study considered very preterm neonates (<32 weeks' gestational age) admitted to a tertiary neonatal intensive care unit from 2012 to 2023. Inclusion criteria required neonates with a complete blood count measured in both UCB and NB drawn within 2 hours after birth. Median hemoglobin (Hb) and hematocrit (Hct) concentrations were compared between UCB (venous samples) and NB (venous, arterial, or capillary samples)...

INTRODUCTION: We aimed to identify factors predictive of adverse maternal and neonatal outcomes in patients with placenta accreta spectrum (PAS) disorders using magnetic resonance imaging (MRI) and intravoxel incoherent motion (IVIM) parameters. METHOD: Fifty-six normal singleton pregnancies at 33-39 weeks of gestation underwent MRI examination at 1.5 T. The IVIM parameters were obtained from the placenta. The correlation between the f value and postpartum hemorrhage (PPH) and between the f value and transfused units of red blood cells (RBCs) was estimated by linear regression...

BACKGROUND: The goal was to develop a risk assessment model for predicting red blood cell (RBC) transfusion in neonatal patients to assist hospital blood supply departments in providing small portions of RBCs to those requiring RBC transfusion on time. METHODS: Clinical information was collected from 1,201 children admitted to the neonatal unit. Clinical factors associated with predicting RBC transfusion were screened, and prediction models were developed using stepwise and multifactorial logistic regression analyses, followed by the evaluation of prediction models using receiver operating characteristic curves, calibration curves, and decision curve analysis (DCA)...

BACKGROUND AND OBJECTIVES: National-level data on the incidence of red blood cell (RBC) transfusions and outcomes among very preterm infants (VPIs) are lacking in China. This study aims to describe the use and variation of RBC transfusion among VPIs in China. MATERIALS AND METHODS: This cohort study was conducted among 70 tertiary hospitals participating in the Chinese Neonatal Network (CHNN) from 2019 to 2020 across China. All VPIs admitted to the CHNN neonatal intensive care units (NICUs) were included...

OBJECTIVE: Infants who meet the screening guidelines for retinopathy of prematurity (ROP) based on birth weight and gestational age undergo serial ophthalmological examinations for its detection and treatment. However, <10% of patients require treatment, and less than half develop ROP. Poor postnatal weight gain has been reported to be a strong indicator of ROP development; however, the information regarding this is unclear. Therefore, this study aimed to determine the relationship between postnatal weight gain and ROP development in preterm infants...

PURPOSE: To compare the clinical characteristics, virus serotype, and outcome in cases of mild and severe enteroviral infection at a tertiary neonatal intensive care unit in China. METHODS: A retrospective analysis of cases hospitalized between June and August 2019. Samples (stool or throat swabs) were examined using reverse transcription polymerase chain reaction. Positive cases were divided into two groups: mild infection and severe infection. RESULTS: A total of 149 cases were assigned to one of two groups: mild infection (n = 104) and severe infection (n = 45)...

BACKGROUND: Placenta accreta syndrome (PAS) may led to heavy blood loss and maternal death. Here we analyzed the main risk factors of PAS+ pregnancies and its complications in a referral hospital in the north of Iran. METHODS: In a case control study, all pregnant women with PAS referred to our department during 2016 till 2021 were enrolled and divided in two groups case (PAS+) and control (PAS-) based on preoperative imaging, intraoperative findings, and pathological reports...

BACKGROUND: Standardization of procedures improves outcomes. Though systematic reviews have summarized the evidence-based steps (EBS) of cesarean delivery (CD), their bundled implementation has not been investigated. OBJECTIVE: In this pre- and post-implementation trial, we sought to ascertain if bundled EBS of CD, compared to surgeon's preference, improves outcomes. STUDY DESIGN: A StaRI (Standards for Reporting Implementation Studies) compliant, multi-center pre- and post-implementation trial at 4 teaching hospitals was conducted...

BACKGROUND AND OBJECTIVES: The isolation of neutrophils and subsequent detection of anti-human neutrophil antigens (HNA) antibodies are crucial in clinical medicine for the diagnosis of autoimmune neutropenia, neonatal alloimmune neutropenia (NAIN) and transfusion-related acute lung injury (TRALI). This study reports two cases of maternal anti-Fc-gamma-receptor-IIIb (FcγRIIIb) isoimmunization without NAIN symptoms and compares the efficiency of immunomagnetic negative selection (IMNS) with traditional dextran/Ficoll for neutrophil isolation in HNA serological assays...

The Rh blood grouping system is a critical standardized test in transfusion medicine, especially for the cases related to haemolytic transfusion reactions and neonatal haemolytic disease caused by clinical RhD blood group incompatibility. In the present case report, we presented two cases with the uncommon RHD gene variation RHD * DEL37 . The blood samples of the two subjects were mistakenly identified as RhD-negative through conventional serological testing. Firstly, both blood samples were tested negative for the RhD antigen using traditional tube test and gel microcolumn methods...

We present the first published case of simultaneous pneumonitis and immune thrombocytopenic purpura secondary to primary cytomegalovirus (CMV) infection in an immunocompetent patient. Treatment with oral valganciclovir for 2 weeks successfully led to complete clinical recovery. CMV is traditionally associated with infection in immunocompromised patients and neonates; however, evidence of severe CMV infections in immunocompetent hosts is emerging. It is important to highlight the broad range of clinical presentations of CMV infections to prevent diagnostic delay and associated morbidity and expense...

Hemolytic disease of the fetus and newborn (HDFN) may cause severe cholestasis with direct bilirubin concentrations reaching up to 50 times the upper limit of normal. This case report describes twins whose highest direct bilirubin concentrations were 32.2 mg/dL and 50.2 mg/dL, with no significant signs of hepatic impairment. The index pregnancy was complicated by Rhesus factor immunization with anti-D antibodies present in maternal serum, which caused fetal anemia requiring intrauterine blood transfusions. Complementary tests demonstrated Rhesus D alloimmunization as the sole cause of cholestasis...

BACKGROUND: Uterine rupture in pregnant women can lead to serious adverse outcomes. This study aimed to explore the clinical characteristics, treatment, and prognosis of patients with complete uterine rupture. METHODS: Data from 33 cases of surgically confirmed complete uterine rupture at Chenzhou No.1 People's Hospital between January 2015 and December 2022 were analyzed retrospectively. RESULTS: In total, 31,555 pregnant women delivered in our hospital during the study period...

BACKGROUND: Placental management strategies such as umbilical cord milking and delayed cord clamping may provide a range of benefits for the newborn. The aim of this review was to assess the effectiveness of umbilical cord milking and delayed cord clamping for the prevention of neonatal hypoglycaemia. METHODS: Three databases and five clinical trial registries were systematically reviewed to identify randomised controlled trials comparing umbilical cord milking or delayed cord clamping with control in term and preterm infants...

OBJECTIVE: To investigate the outcomes associated with the administration of maternal intravenous immunoglobulin (IVIG) in high-risk red blood cell (RBC) alloimmunized pregnancies. DATA SOURCES: We systematically searched Medline, Embase, and Cochrane Library until June 2023. STUDY ELIGIBILITY CRITERIA: We included studies reporting on pregnancies with severe RBC alloimmunization, defined as either a previous fetal or neonatal death or the need for IUT before 24 weeks in the previous pregnancy as a result of hemolytic disease of fetus and newborn (HDFN)...

BACKGROUND: In low-risk pregnancies, third trimester ultrasound examination is indicated if fundal height measurement and gestational age discrepancy is observed. Despite potential improvement in detection of ultrasound abnormality, prior trials to date on universal third trimester ultrasound examination in low-risk pregnancies, compared to indicated ultrasound examination, have not demonstrated improvement in neonatal or maternal adverse outcomes. OBJECTIVE: The primary objective was to determine if universal third trimester ultrasound examination in low-risk pregnancies could attenuate composite neonatal adverse outcome...

OBJECTIVE: To compare rates of adverse pregnancy outcomes in term pregnancies complicated by polyhydramnios between women who had induction of labor (IOB) versus women who had expectant management. METHODS: This multicenter retrospective study included term pregnancies complicated by isolated polyhydramnios. Patients who underwent IOB were compared with those who had expectant management. The primary outcome was defined as a composite adverse maternal outcome, and secondary outcomes were various maternal and neonatal adverse outcomes...
