Maternal and Cord Anti-SARS-CoV-2-Spike IgG following COVID-19 Vaccination versus Infection during Pregnancy: A Prospective Study, Israel October 2021-March 2022.

Objective: Defining how pregnant women respond to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and vaccination is critical to optimize vaccination strategies that protect mother and infant at the epidemic. This study aimed to compare anti-SARS-CoV-2-spike immunoglobulin G (IgG) of vaccinated versus infected women and to determine the optimal timing of maternal vaccination during pregnancy at the time of epidemic.

Study Design: We collected maternal/cord blood at delivery (October 2021-March 2022) and measured anti-SARS-CoV-2-spike IgG geometric mean concentrations (IgG-GMCs) using a quantitative immunoassay.

Compared perinatal outcomes of two prophylactic antibiotic regimens for preterm premature rupture of membranes: a randomized controlled trial.

Background: Prophylactic antibiotic use in preterm premature rupture of membranes is associated with significantly reduced intra-amniotic infection and improved neonatal outcome, although data are insufficient to determine the optimal antibiotic regimen. Ampicillin resistance has changed the epidemiology of neonatal sepsis.

Objective: This study aimed to determine the efficacy of two antibiotic regimens in prolonging the latency period in women with preterm premature rupture of membranes.

Vertical Transmission of Extended-Spectrum, Beta-Lactamase-Producing during Preterm Delivery: A Prospective Study.

Maternal carriage and vertical transmission of extended-spectrum, beta-lactamase-producing (ESBL-E), such as , hamper the treatment of infections, resulting in high morbidity. is the most frequent cause of early-onset neonatal sepsis (EOS) in preterm infants, where ESBL-E are more frequently isolated. In this prospective, case-controlled study, maternal rectovaginal ESBL-E colonization and vertical transmission to preterm infants were assessed in 160 women with preterm premature rupture of membranes (PPROM; 57.

A novel extended prophylactic antibiotic regimen in preterm pre-labor rupture of membranes: A randomized trial.

Objectives: Prophylactic antibiotic use in preterm pre-labor rupture of membranes (PPROM) is associated with a significant reduction in intra-amniotic infection and improved neonatal outcome. However, data is insufficient to determine the optimal antibiotic regimen. Considering the rise in Escherichia coli and Klebsiella pneumonia early-onset sepsis rate and the emergence of ampicillin resistance, our aim is to compare the efficiency of two antibiotic regimens in prolonging pregnancy and reducing infectious morbidity.

Newborn screening for cerebrotendinous xanthomatosis is the solution for early identification and treatment.

Cerebrotendinous xanthomatosis (CTX) is a progressive metabolic leukodystrophy. Early identification and treatment from birth onward effectively provides a functional cure, but diagnosis is often delayed. We conducted a pilot study using a two-tier test for CTX to screen archived newborn dried bloodspots (DBSs) or samples collected prospectively from a high-risk Israeli newborn population.

Two novel mutations identified in familial cases with Donohue syndrome.

Donohue syndrome (DS) is a rare and lethal autosomal recessive disease caused by mutations in the insulin receptor (INSR) gene, manifesting marked insulin resistance, severe growth retardation, hypertrichosis, and characteristic dysmorphic features. We report the clinical, molecular, and biochemical characterization of three new patients with DS, and address genotype-phenotype issues playing a role in the pathophysiology of DS. A female infant born to first-degree cousins Muslim Arab parents and two brothers born to first-degree cousins Druze parents presented classical features of DS with hypertrophic cardiomyopathy and died in infancy.

PNPO deficiency: an under diagnosed inborn error of pyridoxine metabolism.

The rare autosomal recessive disorder pyridoxine 5'-phosphate oxidase (PNPO) deficiency is a recently described cause of neonatal and infantile seizures. Clinical evaluation, and biochemical and genetic testing, were performed on a neonate with intractable seizures who did not respond to anticonvulsant drugs and pyridoxine. Sequencing of the PNPO gene revealed a novel homozygous c.

A cluster of early neonatal sepsis and pneumonia caused by nontypable Haemophilus influenzae.

Nine premature infants developed early onset sepsis and/or pneumonia with Haemophilus influenzae during a period of 53 months (January 2000 -May 2004). Their respiratory problems were pneumonia-like rather than classic respiratory distress syndrome. In 8 of the cases, the pathogen was a beta-lactamase-negative, nontypable H.
