Article Synopsis
  • This study analyzes a large cohort of over 1.6 million children in Korea born between 2009 and 2015 to examine the protective effects of breastfeeding against hospital admissions.
  • Findings reveal that children who were exclusively breastfed had a 15% lower hospital admission rate compared to those who were fully formula-fed, while partially breastfed children had a 12% lower admission rate.
  • The protective benefits of breastfeeding appear to decrease as children age, highlighting the importance of promoting breastfeeding, especially for at least the first 6 months, as a key public health strategy.

Childhood-onset polyarteritis nodosa (PAN) is a rare and systemic necrotising vasculitis in children affecting small- to medium-sized arteries. To date, there have been only a few reports because of its rarity. Thus, we aimed to investigate the clinical manifestations, laboratory findings, treatment, and long-term outcomes in patients with childhood-onset PAN and to evaluate the usefulness of the paediatric vasculitis activity score (PVAS).

Fibrolamellar hepatocellular carcinoma (FLHCC) is a rare liver cancer affecting adolescents and young adults without any pre existing liver disease. Hyperammonemic encephalopathy (HAE) is a serious paraneoplastic syndrome, and several cases of HAE have been reported in patients with FLHCC. This condition is rare; hence, there are currently no management guidelines for cancer-related HAE.

Purpose: Adverse drug events (ADEs) are associated with high health and financial costs and have increased as more elderly patients treated with multiple medications emerge in an aging society. It has thus become challenging for physicians to identify drugs causing adverse events. This study proposes a novel approach that can improve clinical decision making with recommendations on ADE causative drugs based on patient information, drug information, and previous ADE cases.

The CAG repeat length of the androgen receptor (AR) gene, which exhibits an inverse relationship to AR sensitivity, might influence the development of the pubarche along with hyperandrogenemia. There are ethnic differences in the AR CAG repeat length, however, no Asian studies on premature pubarche (PP) have been reported, including Korea. Our objectives were to examine the hormone levels and AR CAG repeat length, and to assess their contributions to PP in Korean girls.

Article Synopsis
  • - The study examined the characteristics of regulatory T cells (Tregs) in young patients with Turner syndrome (TS) who have a 45,X karyotype, comparing them to age-matched healthy controls to see if their frequency and function were altered.
  • - TS patients, regardless of thyroid autoimmunity status, had a lower overall frequency of CD4+ T cells but a higher frequency of FOXP3+ Tregs compared to controls; however, their ability to suppress other T cells was significantly impaired.
  • - Both TS groups showed a decreased presence of naïve T cells and an increased presence of effector memory T cells, indicating dysfunctional immune responses despite a higher quantity of Tregs.

Background: Patients with ALS may be exposed to variable degrees of chronic intermittent hypoxia. However, all previous experimental studies on the effects of hypoxia in ALS have only used a sustained hypoxia model and it is possible that chronic intermittent hypoxia exerts effects via a different molecular mechanism from that of sustained hypoxia. No study has yet shown that hypoxia (either chronic intermittent or sustained) can affect the loss of motor neurons or cognitive function in an in vivo model of ALS.

Aggregation of misfolded protein and resultant intracellular inclusion body formation are common hallmarks of mutant superoxide dismutase (mSOD1)-linked familial amyotrophic lateral sclerosis (FALS) and have been associated with the selective neuronal death. Protein disulfide isomerase (PDI) represents a family of enzymatic chaperones that can fold nascent and aberrant proteins in the endoplasmic reticulum (ER) lumen. Recently, our group found that S-nitrosylated PDI could contribute to protein misfolding and subsequent neuronal cell death.

Article Synopsis
  • - Cu/Zn-superoxide dismutase (SOD1) is found in various parts of human cells, and over 114 genetic variants of SOD1 are linked to familial amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease.
  • - This study focuses on how SOD1 aggregates form and their cytotoxic effects, using methods like spectroscopy and electron microscopy, and finds that structural instability in SOD1 leads to aggregation, especially when the protein loses its metal ions (demetallated form).
  • - The research suggests that lipid molecules enhance the aggregation of SOD1 proteins, particularly the amorphous aggregates formed from demetallated SOD1, and this process may

Hereditary spastic paraplegia with thin corpus callosum (HSP-TCC) is one of the most common complicated forms of autosomal recessive hereditary spastic paraplegia (HSP). Mutation in SPG11 gene, which is mapped to chromosome 15q21, was recently found to be a major cause of this variant form of HSP. The aim of this study is to investigate SPG11 mutations and clinical manifestations in two Korean families with HSP-TCC.
