Hemophagocytic lymphohistiocytosis (HLH) is a rare, life-threatening hyperinflammatory syndrome characterized by uncontrolled activation and proliferation of proinflammatory cytokines. Initial presentation commonly includes fever, hepatosplenomegaly, and pancytopenia; 6 to 65% of cases also have a concurrent cutaneous eruption. We present the case of a 6-day-old premature infant boy with congenital severe thrombocytopenia, anemia, and hepatosplenomegaly who presented with several cutaneous violaceous papules and nodules and was found to have HLH...

OBJECTIVE: To investigate the importance of breastfeeding in preterm infants with various gestational ages. METHODS: A total of 639 preterm infants with a gestational age of 28(+3)-36(+6) weeks were enrolled, and according to the feeding pattern, they were divided into exclusive breastfeeding group (n=237) and formula milk feeding group (fed with liquid milk for preterm infants; n=402). These two feeding patterns were compared in terms of their effects on weight gain, laboratory markers including albumin (Alb) and alkaline phosphatase (ALP), incidence rate of feeding intolerance, and incidence rates of complications including necrotizing enterocolitis (NEC) and retinopathy of prematurity (ROP)...

AbstractPregnant women and their developing fetuses are vulnerable to multiple environmental insults, including exposure to aflatoxin, a mycotoxin that may contaminate as much as 25% of the world food supply. We reviewed and integrated findings from studies of aflatoxin exposure during pregnancy and evaluated potential links to adverse pregnancy outcomes. We identified 27 studies (10 human cross-sectional studies and 17 animal studies) assessing the relationship between aflatoxin exposure and adverse birth outcomes or anemia...

Background: Female survivors of childhood cancer treated with abdominal radiotherapy who manage to conceive are at risk of delivering premature and low-birthweight offspring, but little is known about whether abdominal radiotherapy may also be associated with additional complications during pregnancy and labor. We investigated the risk of developing pregnancy and labor complications among female survivors of childhood cancer in the British Childhood Cancer Survivor Study (BCCSS). Methods: Pregnancy and labor complications were identified by linking the BCCSS cohort (n = 17 980) to the Hospital Episode Statistics (HES) for England...

BACKGROUND: Phlebotomy-induced anemia (PIA) is common in premature infants and affects neurodevelopment. PIA alters hippocampal metabolism in neonatal mice through tissue hypoxia and iron deficiency. The mammalian target of rapamycin (mTOR) pathway senses the status of critical metabolites (e.g., oxygen, iron), thereby regulating hippocampal growth and function. We determined the effect of PIA and recombinant human erythropoietin (rHuEpo) treatment on mTOR signaling and expression of genes related to mTOR pathway functions...

BACKGROUND: Anemia is a common problem in premature infants and its most rapid and effective therapy is erythrocyte transfusion. However, owing to inherent risks of transfusion in this population, transfusions should be administered only when adequate oxygen delivery to tissues is impaired. The aim of this study was to determine tissue acid levels using Stewart method in an attempt to evaluate the tissue oxygenation level and thereby the accuracy of transfusion timing. METHODS: This study included 47 infants delivered at gestational age below 34 weeks who required erythrocyte transfusion for premature anemia...

Congenital erythropoietic porphyria (CEP) is an inborn error of heme biosynthesis characterized by uroporphyrinogen III synthase (UROS) deficiency resulting in deleterious porphyrin accumulation in blood cells responsible for hemolytic anemia and cutaneous photosensitivity. We analyzed here the molecular basis of UROS impairment associated with twenty nine UROS missense mutations actually described in CEP patients. Using a computational and biophysical joint approach we predicted that most disease-causing mutations would affect UROS folding and stability...

The physical growth of young children in low- and middle-income countries is reduced compared to international standards. The deviations in growth in both weight and height are greatest in the first 2 years of life and this has serious consequences for child mortality, development, adult stature, and health. The determinants of these patterns of growth faltering include intergenerational factors, such as maternal height, short birth interval, and conditions in pregnancy, including maternal underweight and anemia...

We report the case of severe retinopathy of prematurity (ROP) in the donor twin with twin anemia-polycythemia sequence managed with the novel treatment of intrauterine blood transfusions. The fellow polycythemic twin was managed with intrauterine venesection and developed only mild ROP. Thus, despite intrauterine improvement of the twins' hemodynamic conditions, the risk of developing severe ROP remained in the donor twin.

BACKGROUND AND OBJECTIVES: The pathogenesis of anemia in hemodialysis (HD) patients is dependent on multiple factors, with decreased red blood cell life span (RBCLS) being a significant contributor. Although the impact of reduced RBCLS on anemia is recognized, it is still a subject that is not well researched. The objective of this study was to investigate the relationship between RBCLS and inflammatory biomarkers in chronic HD patients. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS: RBCLS was calculated from alveolar carbon monoxide concentrations measured by gas chromatography...
