Effects of Ponderal Index on Neonatal Mortality and Morbidities in Extremely Premature Infants.
To evaluate how intrauterine stress affects extremely premature infants in terms of intrauterine growth restriction. We hypothesized that extremely premature infants with mildly-low ponderal index (MPI) would have better neonatal outcomes. ⋯ The MPI and API groups had lower mortality, massive pulmonary hemorrhage, severe bronchopulmonary dysplasia or death, pulmonary hypertension and neonatal seizure rates than the SPI and/or HPI groups, while the MPI group showed a lower incidence of severe IVH than the other groups. We speculate that the lower incidence of neonatal morbidities and mortality in the MPI group indicating mild intrauterine stress might accelerate fetal maturation resulting in better outcomes in extremely premature infants.

Case ReportsTwo Case Reports of Life-Threatening Croup Caused by the SARS-CoV-2 Omicron BA.2 Variant in Pediatric Patients.
Croup is a common upper airway infection characterized by a barking cough, stridor, and hoarseness. It is usually caused by viral infection. A small number of croup caused by coronavirus disease 2019 (COVID-19) has been reported in children before the omicron variant surge. ⋯ Both patients were discharged without complications. To the best of our knowledge, this is the first report of life-threatening croup produced by the omicron BA.2 variant and confirmed by RT-PCR. We suggest that this SARS-CoV-2 variant may cause severe croup that may not improve with conventional treatment, even in children without underlying diseases.

Immunogenicity of COVID-19 Vaccination in Patients With End-Stage Renal Disease Undergoing Maintenance Hemodialysis: The Efficacy of a Mix-and-Match Strategy.
The objective of this study was to evaluate the immunogenicity of coronavirus disease 2019 (COVID-19) vaccination in patients with end-stage renal disease (ESRD) on hemodialysis. ⋯ ESRD patients on hemodialysis receiving the mix-and-match strategy (ChAdOx1-BNT162b2) have COVID-19 vaccine immunogenicity comparable to healthy individuals receiving two doses of ChAdOx1.
