A Survey on Public Perceptions of Low Fertility: A Social Research Panel Study.
It was reported that South Korea showed the greatest decline in the fertility rate among the entire OECD countries over the last 30 years with the total fertility rate (TFR) of 0.84 persons in 2020. Despite the efforts of the Korean government, the TFR has decreased constantly. This study intended to analyze the perception of Koreans toward pregnancy and childbirth regarding the low fertility rate in South Korea for understanding the causes of constantly decreased low fertility. ⋯ This study found that a decrease in the TFR was affected mainly by the negative perception of women in their 20s and 30s toward marriage, childbirth, and the necessity of children. Therefore, further research should be conducted to develop policies that focus on these significant variables to overcome the worsening low fertility problem.

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.

Impact of COVID-19 on Clinicopathological Spectrum of Pityriasis Rosea in Korea.
Pityriasis rosea (PR) is a papulosquamous eruption with generally unknown origin but suspected to be related to viral etiologies. The clinicopathological spectrum of several disorders with viral etiologies has been altered after the coronavirus disease 2019 (COVID-19) pandemic. The author group could experience coherent histological alterations in PR after the COVID-19 pandemic. This study aimed to investigate how the clinicopathological findings of PR were changed after the COVID-19 pandemic. ⋯ In conclusion, PR demonstrated a significant histopathological alteration with more frequent pruritus during the COVID-19 pandemic. The comparative results about clinicopathological findings of PR will provide a useful reference for dermatologists in the diagnostic process of PR in the COVID-19 pandemic.

The Changes in Epidemiology of Imipenem-Resistant Acinetobacter baumannii Bacteremia in a Pediatric Intensive Care Unit for 17 Years.
Acinetobacter baumannii infections cause high morbidity and mortality in intensive care unit (ICU) patients. However, there are limited data on the changes of long-term epidemiology of imipenem resistance in A. baumannii bacteremia among pediatric ICU (PICU) patients. ⋯ IRAB bacteremia causes serious threat in patients in PICU. Proactive infection control measures and antimicrobial stewardship are crucial for managing IRAB infection in PICU.
