A new nairo-like virus associated with human febrile illness in China

3 weeks 4 days ago
ABSTRACTSeveral nairo-like viruses have been discovered in ticks in recent years, but their relevance to public health remains unknown. Here, we found a patient who had a history of tick bite and suffered from a febrile illness was infected with a previously discovered RNA virus, Beiji nairovirus (BJNV), in the nairo-like virus group of the order Bunyavirales. We isolated the virus by cell culture assay. BJNV could induce cytopathic effects in the baby hamster kidney and human hepatocellular...

A single dose of aminophylline administration during therapeutic hypothermia; does it make a difference in glomerular filtration rate?

3 weeks 4 days ago
Aminophylline has been demonstrated to be effective in improving renal functions of the infants suffering from acute kidney injury (AKI) due to perinatal asphyxia. We aimed to evaluate the effect of a single-dose aminophylline on estimated glomerular filtration rate (eGFR), urine output (UO), and incidence and severity of AKI according to the pediatric-modified RIFLE and neonatal RIFLE criteria in newborns with perinatal asphyxia under therapeutic hypothermia. This was a single-center,...

TARP syndrome associated with renal malformation and optic nerve atrophy

4 weeks ago
Talipes equinovarus, atrial septal defect, Robin sequence and persistent left superior vena cava (TARP) syndrome is a congenital disease caused by mutations in the RBBM10 gene. It has a low prevalence and a high rate of mortality in the neonatal stage. In this case report, we present a case of a 32-week gestational age preterm newborn with a prenatal diagnosis of intrauterine growth restriction, with a persistent left superior vena cava, interatrial communication and a horseshoe kidney....

Abnormal neonatal sodium handling in skin precedes hypertension in the SAME rat

4 weeks 1 day ago
We discovered high Na^(+) and water content in the skin of newborn Sprague-Dawley rats, which reduced ~ 2.5-fold by 7 days of age, indicating rapid changes in extracellular volume (ECV). Equivalent changes in ECV post birth were also observed in C57Bl/6 J mice, with a fourfold reduction over 7 days, to approximately adult levels. This established the generality of increased ECV at birth. We investigated early sodium and water handling in neonates from a second rat strain, Fischer, and an...

Diuretic therapy and acute kidney injury in preterm neonates and infants

1 month ago
CONCLUSIONS: Preterm infants with AKI diagnosis were frequently treated with diuretics. Moreover, infants with younger GA and smaller birth weight were more likely to receive diuretics. Worse survival in infants with older GA who received diuretics could be the result of more underlying severe illness in these infants and not the cause of more severe illness. Prospective studies are needed to best determine patient safety and outcomes with diuretic treatment in preterm infants with AKI. A higher...

Non-Human Glycans Can Regulate Anti-FVIII Antibody Formation in Mice

1 month ago
Recombinant Factor VIII (FVIII) products represent a life-saving intervention for patients with hemophilia A. However, patients can develop antibodies against FVIII that prevent FVIII function and directly increase morbidity and mortality. The development of anti-FVIII antibodies varies depending on the type of recombinant product employed, with previous studies suggesting that 2nd generation baby hamster kidney (BHK)-derived FVIII products display greater immunogenicity than 3rd generation...

Infant presenting with pyloric stenosis and autosomal recessive polycystic kidney disease at 36 weeks' postmenstrual age (PMA)

1 month ago
This case report describes a premature male infant born after a pregnancy complicated by oligohydramnios of unknown aetiology but otherwise unremarkable prenatal scans. He had sudden onset of projectile emesis and severe hypertension in the third week of life, and further investigations revealed both pyloric stenosis and polycystic kidneys, at just 36 weeks' postmenstrual age (PMA). His course thereafter was complicated by severe refractory hypertension requiring multiple antihypertensive agents...

Valsartan exposure in pregnancy with resultant anhydramnios and chronic kidney disease in a late preterm infant

1 month ago
In utero exposure to angiotensin II receptor blockers (ARBs) has fetotoxic effects including renal failure, oligohydramnios and lung hypoplasia. We present the case of a 24-year-old woman who presented to the maternity services in the 34th week of her first pregnancy. She was taking valsartan for hypertension. Ultrasound showed a structurally normal fetus with anhydramnios. The patient was admitted and valsartan was discontinued. She had spontaneous preterm delivery at 35 weeks' gestation of a...

Impact of Acute Kidney Injury on Critically Ill Children and Neonates

1 month 1 week ago
Acute kidney injury (AKI) is a clinical syndrome that manifests as an abrupt impairment of kidney function. AKI is common in critically ill pediatric patients admitted to the pediatric intensive care units. AKI is a deleterious complication in critically ill children as it is associated with increased morbidity and mortality. This review provides an overview of the incidence, morbidity, and mortality of AKI in critically ill children in general and specific cohorts such as post-cardiac...

Human Liver Stem Cells: A Liver-Derived Mesenchymal Stromal Cell-Like Population With Pro-regenerative Properties

1 month 1 week ago
Human liver stem cells (HLSCs) were described for the first time in 2006 as a new stem cell population derived from healthy human livers. Like mesenchymal stromal cells, HLSCs exhibit multipotent and immunomodulatory properties. HLSCs can differentiate into several lineages under defined in vitro conditions, such as mature hepatocytes, osteocytes, endothelial cells, and islet-like cell organoids. Over the years, HLSCs have been shown to contribute to tissue repair and regeneration in different...

Serum Creatinine and Serum Cystatin C are Both Relevant Renal Markers to Estimate Vancomycin Clearance in Critically Ill Neonates

1 month 1 week ago
Purpose: Serum creatinine (SCr) is used as a marker of kidney function to guide dosing of renally eliminated drugs. Serum Cystatin C (S-CysC) has been suggested as a more reliable kidney marker than SCr in adults and children. Purpose of this study was to investigate S-CysC as alternative renal marker to SCr for estimating vancomycin clearance in neonates undergoing intensive care. Methods: Vancomycin pharmacokinetics (PK), SCr and S-CysC data were collected in patients undergoing vancomycin...

Fluid Balance in the Critically Ill Child Section: "How Bad Is Fluid in Neonates?"

1 month 2 weeks ago
Fluid overload (FO) in neonates is understudied, and its management requires nuanced care and an understanding of the complexity of neonatal fluid dynamics. Recent studies suggest neonates are susceptible to developing FO, and neonatal fluid balance is impacted by multiple factors including functional renal immaturity in the newborn period, physiologic postnatal diuresis and weight loss, and pathologies that require fluid administration. FO also has a deleterious impact on other organ systems,...
