1.Novel functional roles of caspase-related genes in the regulation of apoptosis and autophagy.
The Korean Journal of Physiology and Pharmacology 2016;20(6):573-580
Caspases, a family of cysteine proteases, cleave substrates and play significant roles in apoptosis, autophagy, and development. Recently, our group identified 72 genes that interact with Death Caspase-1 (DCP-1) proteins in Drosophila by genetic screening of 15,000 EP lines. However, the cellular functions and molecular mechanisms of the screened genes, such as their involvement in apoptosis and autophagy, are poorly understood in mammalian cells. In order to study the functional characterizations of the genes in human cells, we investigated 16 full-length human genes in mammalian expression vectors and tested their effects on apoptosis and autophagy in human cell lines. Our studies revealed that ALFY, BIRC4, and TAK1 induced autophagy, while SEC61A2, N-PAC, BIRC4, WIPI1, and FALZ increased apoptotic cell death. BIRC4 was involved in both autophagy and apoptosis. Western blot analysis and luciferase reporter activity indicated that ALFY, BIRC4, PDGFA, and TAK1 act in a p53-dependent manner, whereas CPSF1, SEC61A2, N-PAC, and WIPI1 appear to be p53-independent. Overexpression of BIRC4 and TAK1 caused upregulation of p53 and accumulation of its target proteins as well as an increase in p53 mRNA levels, suggesting that these genes are involved in p53 transcription and expression of its target genes followed by p53 protein accumulation. In conclusion, apoptosis and/or autophagy mediated by BIRC4 and TAK1 may be regulated by p53 and caspase activity. These novel findings may provide valuable information that will aid in a better understanding of the roles of caspase-related genes in human cell lines and be useful for the process of drug discovery.

Osteogenesis imperfecta is a heterogeneous group of disorders that are characterized by connective tissue defects resulting in bone fragility, blue sclera, impaired hearing, defective dentition, and hyperlaxibility of the joints. The overall incidence of osteogenesis imperfecta is estimated at 1/25,000. We recently experienced a case of osteogenesis imperfecta type II diagnosed in uterus by ultrasonogram and confirmed after termination of pregnancy and autopsy. We report a case here with a brief review of the literature.

The prenatal diagnosis of spina bifida includes the combined use of maternal serum alpha-fetoprotein (MSAFP) screening and fetal sonography. On ultrasonogram, spina bifida is characterizd by visualization of the spinal defect and associated cranial abnomalities: the Lemon sign, the Banana sign, ventriculomegaly, small biparietal diameter, and obliteration of the cisterna magna. We should now be able to rely on ultrasound as the main technique for diagnosis of spina bifida when MSAFP is elevated. Recently, we have experienced three cases of spina bifida diagnosed with meningomyelocele, lemon sign, banana sign and ventriculomegaly on ultrasonogram at respectively 18+3, 18, and 18+6 weeks of gestation. We present these cases with a brief review of literatures.

OBJECTIVES:
This study explored socioeconomic disparities in Korea using health insurance type as a proxy during the ongoing coronavirus disease 2019 (COVID-19) pandemic.
METHODS:
We conducted a retrospective cohort study using Korea’s nationwide healthcare database, which contained all individuals who received a diagnostic test for COVID-19 (n=232,390) as of May 15, 2020. We classified our cohort by health insurance type into beneficiaries of the National Health Insurance (NHI) or Medicaid programs. Our study outcomes were infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and COVID-19-related outcomes, a composite of all-cause death, intensive care unit admission, and mechanical ventilation use. We estimated age-, sex-, and Charlson comorbidity index score–adjusted odds ratios (aORs) with 95% confidence intervals (CIs) using a multivariable logistic regression analysis.
RESULTS:
Of the 218,070 NHI and 14,320 Medicaid beneficiaries who received COVID-19 tests, 7,777 and 738 tested positive, respectively. The Medicaid beneficiaries were older (mean age, 57.5 vs. 47.8 years), more likely to be males (47.2 vs. 40.2%), and had a higher comorbidity burden (mean CCI, 2.0 vs. 1.7) than NHI beneficiaries. Compared to NHI beneficiaries, Medicaid beneficiaries had a 22% increased risk of SARS-CoV-2 infection (aOR, 1.22; 95% CI, 1.09 to 1.38), but had no significantly elevated risk of COVID-19-related outcomes (aOR 1.10, 95% CI 0.77 to 1.57); the individual events of the composite outcome yielded similar findings.
CONCLUSIONS
As socioeconomic factors, with health insurance as a proxy, could serve as determinants during the current pandemic, pre-emptive support is needed for high-risk groups to slow its spread.

In order to observe the arrhythmia which occured in early convalescent phase of acute myocardial infarction, a 24 hour ambulartory ECG monitiring was performed in 15 patients who is admitted at dept of Int Medicine, Ewha Womans University hospital from Aug. 1985 to Sept. 1986. during 7.5+/-3.4 days after admission. In all cases one or more of the following arrhythmias were observed;atrial premature beat, ventricular premature beat(VPB), transient paroxysmal ventricular thchycardia, atrial fibrillation, sinus arrest and junctional beat. Of 15 cases, 11(77.3%) had VPB's:Simple VPB's in 4 cases(26.7%) and complex VPB's(6.52+/-2.52)(P<0.05). But there were no difference of premature and abberancy index between complex VPB's and simple VPB's(P>0.1). In addition, we compaired the arrhythmias in CCU with those of early convalescent phase of acute myocardial infarction. But there was no correlation between them.

BACKGROUND: The purpose of this study was to evaluate the usefulness and safety of the anterosuperior deltoid splitting approach for fixation of displaced proximal humeral fractures by analyzing the surgical outcomes. METHODS: Twenty-three patients who could be followed-up for at least 8 months after the treatment of displaced proximal humeral fractures through the anterosuperior deltoid splitting approach were enrolled. We evaluated the reduction of the fractures and surgery-related complications at the last follow-up using X-ray results and clinical outcomes comprising the University of California at Los Angeles (UCLA) scoring system and the Korean Shoulder Society (KSS) score. RESULTS: At the last follow-up of patients treated using the anterosuperior deltoid splitting approach for internal fixation of proximal humeral fractures, we found 22 cases (95.6%) of bone union, a mean UCLA score of 28.3 (range, 15 to 34) and a mean KSS score of 82.1 (range, 67 to 95). Various surgery-related complications were noted; a case of varus malunion after fracture displacement, a case of nonunion, a case of delayed union, two cases of impingement, and a case of partial axillary nerve injury, which recovered completely through the follow-up. CONCLUSIONS: Plate fixation using the anterosuperior deltoid splitting approach could be another reliable option for treating displaced proximal humeral fractures.
