Background: Metabolic syndrome (MetS) is reportedly a crucial risk factor for coronavirus disease 2019 (COVID-19). Since the epidemiological studies that examine this association are few and include small samples, we investigated the relationship between MetS and COVID-19 severity and death using a larger sample in the Republic of Korea. Methods: We analyzed 66,321 patients, 4,066 of whom had COVID-19. We used chi-square tests to examine patients’ characteristics. We performed logistic regression analysis to analyze differences in COVID-19 infection and clinical outcomes according to the presence of MetS. Results: Although MetS was not significantly associated with COVID-19 risk, acquiring MetS was significantly associated with the risk of severe COVID-19 outcomes (odds ratio [OR], 1.97; 95% confidence interval [CI], 1.34 to 2.91; P=0.001). The mortality risk was significantly higher in COVID-19 patients with MetS (OR, 1.74; 95% CI, 1.17 to 2.59; P=0.006). Patients with abnormal waist circumference were approximately 2.07 times more likely to develop severe COVID-19 (P<0.001), and high-density lipoprotein cholesterol (HDL-C) levels were significantly associated with COVID-19; the mortality risk due to COVID-19 was 1.74 times higher in men with an HDL-C level of <40 mg/dL and in women with an HDL-C level of <50 mg/dL (P=0.012). Conclusion COVID-19 is likely associated with severity and death in patients with MetS or in patients with MetS risk factors. Therefore, patients with MetS or those with abnormal waist circumference and HDL-C levels need to be treated with caution.

Background: Based on the reports of low prevalence and severity of pediatric severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections, the Korean government has released new SARS-CoV-2 infection response and treatment guidelines for children under the age of 12 years. The government has further directed school reopening under strict preventive measures. However, there is still considerable concern on the impact of school reopening on community transmission of Coronavirus disease 2019 (COVID-19). In the present study, we aimed to evaluate the appropriateness of these directives and the severity of SARS-CoV-2 infections in children as compared to adults using sufficient national sample data. Methods: In the present study, we evaluated the severity of SARS-CoV-2 infection in pediatric patients as compared to adults by analyzing the length of hospital stays (LOS), medical expenses, and hospital and intensive care unit (ICU) admission rates. A multivariate linear regression analysis was carried out to examine the effects of COVID-19 patients that the characteristics on the LOS and medical expenses, and multivariate logistic regression analysis were performed to identify COVID-19 characteristics that affect hospital and ICU admission rates and to prove the low SARS-CoV-2 infection severity in pediatric patients. Results: The hospitalization period for children aged 0–9 was 37% shorter and that of patients aged 10–19 years was 31% shorter than those of older age groups (P < 0.001). The analysis of the medical expenses by age showed that on average, medical expenses for children were approximately 4,900 USD lower for children than for patients over 80 years of age. The linear regression analysis also showed that patients who were 0–9 years old spent 87% and those aged 10–19 118% less on medical expenses than those aged 70 and over, even after the correction of other variables (P < 0.001). The probability of hospitalization was the lowest at 10–19 years old (odds ratio [OR], 0.05; 95% confidence interval [CI], 0.03–0.09), and their ICU admission rate was also the lowest at 0.14 (OR, 0.14; 95% CI, 0.08–0.24). On the other hand, the likelihood of hospitalization and ICU admission was the highest in children aged 0–9 years, and among patients under the age of 50 years in general. Conclusion This study demonstrated the low severity of SARS-CoV-2 infection in younger patients (0–19 years) by analyzing the LOS, medical expenses, hospital, and intensive care unit admission rates as outcome variables. As the possibility to develop severe infection of coronavirus at the age of 10–19 was the lowest, a mitigation policy is also required for middle and high school students. In addition, children with underlying diseases need to be protected from high-risk infection environments.

PURPOSE: Nutritional therapy (NT), such as enteral nutrition (EN) or parenteral nutrition (PN), is essential for the malnourished patients. Although the complications related to NT has been well described, multicenter data on symptoms in the patients with receiving NT during hospitalization are still lacking. METHODS: Nutrition support team (NST) consultations, on which NT-related complications were described, were collected retrospectively for one year. The inclusion criteria were patients who were (1) older than 18 years, (2) hospitalized, and (3) receiving EN or PN at the time of NST consultation. The patients' demographics (age, sex, body mass index [BMI]), type of NT and type of complication were collected. To compare the severity of each complication, the intensive care unit (ICU) admission, hospital stay, and type of discharge were also collected. RESULTS: A total of 14,600 NT-related complications were collected from 13,418 cases from 27 hospitals in Korea. The mean age and BMI were 65.4 years and 21.8 kg/m2. The complications according to the type of NT, calorie deficiency (32.4%, n=1,229) and diarrhea (21.6%, n=820) were most common in EN. Similarly, calorie deficiency (56.8%, n=4,030) and GI problem except for diarrhea (8.6%, n=611) were most common in PN. Regarding the clinical outcomes, 18.7% (n=2,158) finally expired, 58.1% (n=7,027) were admitted to ICU, and the mean hospital days after NT-related complication were 31.3 days. Volume overload (odds ratio [OR]=3.48) and renal abnormality (OR=2.50) were closely associated with hospital death; hyperammonemia (OR=3.09) and renal abnormality (OR=2.77) were associated with ICU admission; “micronutrient and vitamin deficiency” (geometric mean [GM]=2.23) and volume overload (GM=1.61) were associated with a longer hospital stay. CONCLUSION: NT may induce or be associated with several complications, and some of them may seriously affect the patient's outcome. NST personnel in each hospital should be aware of each problem during nutritional support.

Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) is a subtype of dominantly inherited leukoencephalopathies caused by novel CSF1R gene mutation predominantly affecting the cerebral white matter. High signal lesions on diffusion weighted image (DWI) are characteristic. Herein, we describe a patent with ALSP with a novel mutation. The patient had persistent DWI lesions, worsening white matter changes associated with rapidly progressive clinical symptoms.

PURPOSE: To analyze postoperative complications for gastric cancer patients undergoing laparoscopic gastrectomy in single institution over long period of time. METHODS: The data of 1332 consecutive patients undergoing laparoscopic gastrectomy for gastric cancer at a single institution from January 2007 to December 2015 were reviewed. The patients were classified into the early or late surgery group; the initial 100 cases were classified as the initial group. We compared between the two groups and analyzed risk factors for postoperative complications. RESULTS: A total of 265 postoperative complications occurred in 223 patients (16.7%). Major complications occurred in 38 patients (2.9%) including 1 death (0.1%). Operative time and hospital stay were significantly shorter in the late group. Blood loss was greater in the initial group. Sex, comorbidity, tumor location, D2 LND, operative method, non B-I anastomosis, co-resection, long operative time, and blood loss were significant risk factors for overall postoperative complication. In the multivariate analysis, male sex, comorbidity, D2 lymph node dissection, total or proximal gastrectomy, non B-I anastomosis, co-resection, operative time and blood loss were associated with postoperative overall complications. CONCLUSION: Sex, co-morbidity, D2 LND, operative method, co-resection, operative time and blood loss revealed as the risk factor of overall postoperative complication. And there was no significant differences of risk factor related to postoperative complication between initial and maturation surgical period. This suggests that beginners also can safely perform laparoscopic gastrectomy through the appropriate patient selection.
