PURPOSE: Hypothermia at admission is associated with increased mortality and morbidity in preterm infants. We performed a quality improvement (QI) effort to determine the impact of a decrease in admission hypothermia in preterm infants. METHODS: The study enrolled very low birth weight (VLBW) infants born at Gangnam Severance Hospital between January 2013 and December 2016. This multidisciplinary QI effort included the use of occlusive wraps, warm blankets, and caps; the delivery room temperature was maintained above 23.0℃, and a check-list was used for feedback. RESULTS: Among 259 preterm infants, the incidence of hypothermia (defined as body temperature <36.0℃) decreased significantly from 68% to 41%, and the mean body temperature on neonatal intensive care unit admission increased significantly from 35.5℃ to 36.0℃. In subgroup analysis of VLBW infants, admission hypothermia and neonatal outcomes were compared between the pre-QI (n=55) and post-QI groups (n=75). Body temperature on admission increased significantly from 35.4℃ to 35.9℃ and the number of infants with hypothermia decreased significantly from 71% to 45%. There were no cases of neonatal hyperthermia. The incidence of pulmonary hemorrhage was significantly decreased (P=0.017). Interaction analysis showed that birth weight and gestational age were not correlated with hypothermia following implementation of the protocol. CONCLUSION: Our study demonstrated a significant reduction in admission hypothermia following the introduction of a standardized protocol in our QI effort. This resulted in an effective reduction in the incidence of massive pulmonary hemorrhage.

PURPOSE: Salvage operation is performed to improve the functional deficit of vascular access. This study is planned to evaluate the utility of the hybrid surgery through a comparative analysis between the results of surgical thrombectomy and those of hybrid surgery, combining surgical methods and endovascular treatments. METHODS: From January 2007 to December 2008, surgical thrombectomy had been done to 55 patients, whereas hybrid surgery had been done to 111 patients from January 2009 to December 2011. We have done a comparative analysis on the patency rate after the salvage operation for each group, retrospectively. Medical records were reviewed for patient information and radiographic data was used for checking the stenosis site in the hybrid surgery group. RESULTS: There were no statistically significant differences between the two groups, including age, gender, diabetes status, hypertension, and vascular access site or type. The primary patency rate was significantly higher in arteriovenous fistulas (65%) compared with arteriovenous grafts group (55%), at 12 months (P<0.01). At one year after the salvage operation, the secondary patency rate was higher in the hybrid surgery group compared to the surgical thrombectomy group (43.8% vs. 23.7%, P<0.01). CONCLUSION: This study shows that hybrid surgery combining surgical methods and endovascular treatments can be more useful for the salvaging of thrombosed vascular access than performing only surgical thrombectomy.

As North Korea’s healthcare sector loses functionality under the collapsing socialist system, the gap in medical care between North and South Korea is widening. As a result, we expect that the social safety network will disintegrate in the medical field after unification, and in view of this, our study analyzes the infants and mothers who are likely to be most affected at this time to establish a direction for the promotion of unification in the future. Maternal health in North and South Korea was analyzed by the prevalence of anemia, maternal mortality ratio, prenatal and postpartum visits, and child health was analyzed by chronic malnutrition, vaccination penetration rate, and infant mortality rate to evaluate North Korea's poor nutritional conditions and medical system. The introduction of the legal system related to maternal and child health in North and South Korea includes prenatal and postpartum management and labor. Under this legal system, North Korea includes accessibility to hospitals and children's nutrition management issues, and South Korea includes subfertility treatment and postpartum care centers. As a countermeasure to the low birth rate problem emerging in both countries, the governments are providing work leave and economic support. In order to make effective use of the maternal health indicators from a unified scientific perspective, they should be calculated and codeveloped by both North and South Korea, and a multifaceted approach is needed through the setting of additional indicators such as the perinatal mortality rate.

Patient blood management is an evidence-based concept that seeks to minimize blood loss by maintaining adequate hemoglobin levels and optimizing hemostasis during surgery. Since the coronavirus disease 2019 pandemic, patient blood management has gained significance due to fewer blood donations and reduced amounts of blood stored for transfusion. Recently, the prevalence of postpartum hemorrhage (PPH), as well as the frequency of PPH-associated transfusions, has steadily increased. Therefore, proper blood transfusion is required to minimize PPH-associated complications while saving the patient’s life. Several guidelines have attempted to apply this concept to minimize anemia during pregnancy and bleeding during delivery, prevent bleeding after delivery, and optimize recovery methods from anemia. This study systematically reviewed various guidelines to determine blood loss management in pregnant women.

Background: Discontinuing growth hormone (GH) treatment during the transition to adulthood has been associated with adverse health outcomes in patients with childhood-onset growth hormone deficiency (CO-GHD). This study investigated the metabolic changes associated with interrupting GH treatment in adolescents with CO-GHD during the transition period. Methods: This study included 187 patients with CO-GHD who were confirmed to have adult GHD and were treated at six academic centers in Korea. Data on clinical parameters, including anthropometric measurements, metabolic profiles, and bone mineral density (BMD) at the end of childhood GH treatment, were collected at the time of re-evaluation for GHD and 1 year after treatment resumption. Results: Most patients (n=182, 97.3%) had organic GHD. The median age at treatment discontinuation and re-evaluation was 15.6 and 18.7 years, respectively. The median duration of treatment interruption was 2.8 years. During treatment discontinuation, body mass index Z-scores and total cholesterol, low-density lipoprotein, and non-high-density lipoprotein (HDL) cholesterol levels increased, whereas fasting glucose levels decreased. One year after GH treatment resumption, fasting glucose levels, HDL cholesterol levels, and femoral neck BMD increased significantly. Longer GH interruption (>2 years, 60.4%) resulted in worse lipid profiles at re-evaluation. The duration of interruption was positively correlated with fasting glucose and non-HDL cholesterol levels after adjusting for covariates. Conclusion GH treatment interruption during the transition period resulted in worse metabolic parameters, and a longer interruption period was correlated with poorer outcomes. GH treatment should be resumed early in patients with CO-GHD during the transition period.

A thirty-nine year old woman was consulted because of personality change, agitation and memory disturbance. She received chemotherapy and oral steroids because of carcinoma within the bronchus. She had a high serum osmolarity caused by hyperglycemia and hypernatremia, and it was corrected rapidly. Her brain MRI showed EPM (extrapontine myelinolysis). Brain SPECT showed hypoperfusion in the bilateral orbitofrontal regions. We report a patient with EPM with typical frontal lobe dysfunction as an initial manifestation and bilateral orbitofrontal hypoperfusion.

Viral shedding lasted 31 and 19 days from symptom onset in two patients with east respiratory syndrome coronavirus (MERS-CoV) pneumonia, respectively. Environmental real-time RT-PCR was weakly positive for bed guardrail and monitors. Even after cleaning the monitors with 70% alcohol-based disinfectant, RT-PCR was still weakly positive, and converted to negative only after wiping with diluted sodium chlorite. Further studies are required to clarify the appropriate methods to clean environments during and after treatment of patients with MERS-CoV infection.

PURPOSE: The purpose of this study was to examine the effect of black soybean (CJ-3) testa extracts on lipid profiles in streptozotocin (STZ)-induced diabetic rats. METHODS: One control group and four STZ-induced diabetic groups with different doses of black soybean (CJ-3) testa extracts treatment [0 mg/kg (diabetic control, EX), 250 mg/kg (EX-250), 500 mg/kg (EX-500), 1,000 mg/kg (EX-1000)] were orally administered for 4 weeks. RESULTS: All CJ-3 treatment groups had remarkably lower serum triglyceride (TG) levels than that of EX group (p < 0.05) whereas hepatic TG contents did not show any differences. Results from serum total cholesterol (TC) concentrations of EX-250 and EX-1000 groups were decreased compared to EX group (p < 0.05). Furthermore, protein levels of 3-hydroxy-3-methyl-glutaryl-Coenzyme A (HMG-CoA) reductase from the liver decreased in all treatment groups (p < 0.05). However, significant differences were not observed in serum glucose and insulin, and glucose transporter 4 (GLUT-4) protein expression in skeletal muscle tissue. CONCLUSION: These results suggest that black soybean testa extracts could be useful for improvement of hyperlipidemia and hypercholesteremia in diabetes.
