Diffusion-weighted MRI of the liver: issues plus some solutions for the quantification involving evident diffusion coefficient and intravoxel incoherent movement.
0 ± 6.5 vs. 6.2 ± 2.6 μ/mL, respectively; P = 0.023) and also significantly higher in patients who achieved HR compared to those who did not (17.9 ± 5.3 vs. 6.8 ± 2.5 μ/mL, respectively; P = 0.02). The optimal TL for predicting MH was 8.76 μ/mL. CONCLUSION Serum ADL TLs at 16 weeks were significantly higher in pediatric patients with CD who achieved MH and HR, respectively. TDM may guide in optimizing treatment efficacy and better target MH in the era of treat-to-target. © 2020 The Korean Academy of Medical Sciences.BACKGROUND Anesthesia during pregnancy for non-obstetric surgery is generally known to have a negative impact on maternal and fetal outcomes. We assessed the risk of adverse outcomes in fetuses and mothers associated with non-obstetric surgery. METHODS This retrospective study analyzed clinical data on pregnant women who received non-obstetric surgeries at a tertiary university hospital. We reviewed maternity admissions using hospital administrative data during the last 16 years. The outcome assessment included the presence of preterm labor, premature birth, abortion, or stillbirth and the data of newborns. Statistical analyses were performed using the t-test, χ² test, and multiple logistic regression was used for risk analysis. RESULTS The incidence of non-obstetric surgery during pregnancy was 0.96%. Gestational age at or above 20 weeks increased the risk of all adverse events 4.5 fold when it was compared to gestational age less than 20 weeks, although the events were only preterm labor or premature birth and no fetal loss. All fetal loss cases occurred in patients at less than 20 weeks of pregnancy. The risk of adverse outcome increased by 2% for every 1 minute increase in anesthesia time. Babies of the mothers who had the adverse outcome event showed lower birth weight and higher neonatal intensive care unit admission rate than those of babies of the mothers without any adverse event after the surgery. CONCLUSION Physicians should acknowledge and prepare for common possible adverse events at the stage of pregnancy after non-obstetric surgery, and effort to shorten the duration of surgery and anesthesia is needed. © 2020 The Korean Academy of Medical Sciences.BACKGROUND Patients who achieve a return of spontaneous circulation (ROSC) with prolonged cardiac arrest have been recognized to have a poor prognosis. This might lead to reluctance in the provision of post-resuscitation care. Hence, we evaluated the impact of cardiac arrest time on neurologic outcomes in out-of-hospital cardiac arrest (OHCA) patients. METHODS This cross-sectional study used a hospital-based nationwide registry of OHCAs in Korea between 2012 and 2016. All witnessed OHCA patients aged ≥ 15 years and treated with targeted temperature management were included. We collected the time from collapse to sustained ROSC, which was defined as the downtime. The primary outcome was a favorable neurological outcome at hospital discharge. A multiple logistic regression analysis was conducted to determine independent factors for primary outcome in patients with downtime > 30 minutes. RESULTS Overall, neurologically favorable outcome rates were 30.5% in 1,963 patients. When the downtime was stratified into categories of 0-10, 11-20, 21-30, 31-40, 41-50, 51-60, and > 60 minutes according to 10-minute intervals, neurologically favorable outcome rates were 58.2%, 52.3%, 37.3%, 24.6%, 14.1%, 17.4%, and 16.7%, respectively (P 30 minutes, age 51-70 years (odds ratio [OR], 5.35; 95% confidence interval [CI], 2.50-11.49), age ≤ 50 years (OR, 13.16; 95% CI, 6.06-28.57), shockable rhythm (OR, 3.92; 95% CI, 2.71-5.68), bystander resuscitation (OR, 1.80; 95% CI, 1.27-2.55), cardiac cause (OR, 3.50; 95% CI, 1.69-7.25), percutaneous coronary intervention (OR, 1.82; 95% CI, 1.18-2.81), and downtime ≤ 40 minutes (OR, 2.02; 95% CI, 1.42-2.88) were associated with favorable neurological outcomes. CONCLUSION In patients with prolonged downtime, predicting favorable neurologic outcome may be multifactorial. The cutoff value for downtime is not the only determining factor to provide post-resuscitation care. © 2020 The Korean Academy of Medical Sciences.BACKGROUND Despite improvements in palliative care for critically ill children, the characteristics of end-of-life care for pediatric patients with advanced heart disease are not well-known. We investigated these characteristics among hospitalized children with advanced heart disease in a tertiary referral center in Korea. METHODS We retrospectively reviewed the records of 136 patients with advanced heart disease who died in our pediatric department from January 2006 through December 2013. RESULTS The median age of patients at death was 10.0 months (range 1 day-28.3 years). The median duration of the final hospitalization was 16.5 days (range 1-690 days). Most patients (94.1%) died in the intensive care unit and had received mechanical ventilation (89.7%) and inotropic agents (91.2%) within 24 hours of death. The parents of 74 patients (54.4%) had an end-of-life care discussion with their physician, and the length of stay of these patients in the intensive care unit and in hospital was longer. Of the 90 patients who had been hospitalized for 7 days or more, the parents of 54 patients (60%) had a documented end-of-life care discussion. The time interval from the end-of-life care discussion to death was 3 days or less for 25 patients. Eliglustat clinical trial CONCLUSION Children dying of advanced heart disease receive intensive treatment at the end of life. Discussions regarding end-of-life issues are often postponed until immediately prior to death. A pediatric palliative care program must be implemented to improve the quality of death in pediatric patients with heart disease. © 2020 The Korean Academy of Medical Sciences.BACKGROUND Previous studies on inter-rater reliability of pediatric triage systems have compared triage levels classified by two or more triage providers using the same information about individual patients. This overlooks the fact that the evaluator can decide whether or not to use the information provided. The authors therefore aimed to analyze the differences in the use of vital signs for triage modification in pediatric triage. METHODS This was an observational cross-sectional study of national registry data collected in real time from all emergency medical services beyond the local emergency medical centers (EMCs) throughout Korea. Data from patients under the age of 15 who visited EMC nationwide from January 2016 to December 2016 were analyzed. Depending on whether triage modifications were made using respiratory rate or heart rate beyond the normal range by age during the pediatric triage process, they were divided into down-triage and non-down-triage groups. The proportions in the down-triage group were analyzed according to the triage provider's profession, mental status, arrival mode, presence of trauma, and the EMC class.
