RESUMEN
Background/Aims@#The pathophysiology of lean nonalcoholic fatty liver disease (NAFLD) is unclear but has been shown to be associated with more diverse pathogenic mechanisms than that of obese NAFLD. We investigated the characteristics of genetic or metabolic lean NAFLD in a health checkup cohort. @*Methods@#This retrospective cross-sectional study analyzed single nucleotide polymorphism data for 6,939 health examinees. Lean individuals were categorized according to a body mass index cutoff of 23 kg/m 2 . Single nucleotide polymorphisms were analyzed using genotyping arrays. @*Results@#The prevalence of lean NAFLD was 21.6% among all participants with NAFLD, and the proportion of lean NAFLD was 18.5% among lean participants. The prevalence of metabolic syndrome and diabetes among lean patients with NAFLD was 12.4% and 10.4%, respectively.Lean NAFLD appeared to be metabolic-associated in approximately 20.1% of patients. The homozygous minor allele (GG) of PNPLA3 (rs738409) and heterozygous minor alleles (CT, TT) of TM6SF2 (rs58542926) were associated with lean NAFLD. However, the prevalence of fatty liver was not associated with the genetic variants MBOAT7 (rs641738), HSD17B13 (rs72613567), MARC1 (rs2642438), or AGXT2 (rs2291702) in lean individuals. Lean NAFLD appeared to be associated with PNPLA3 or TM6SF2 genetic variation in approximately 32.1% of cases. Multivariate risk factor analysis showed that metabolic risk factors, genetic risk variants, and waist circumference were independent risk factors for lean NAFLD. @*Conclusions@#In a considerable number of patients, lean NAFLD did not appear to be associated with known genetic or metabolic risk factors. Further studies are required to investigate additional risk factors and gain a more comprehensive understanding of lean NAFLD.

Background@#Little is known about the adverse events (AEs) associated with coronavirus disease 2019 (COVID-19) vaccination in patients with type 2 diabetes mellitus (T2DM). @*Methods@#This study used vaccine AE reporting system data to investigate severe AEs among vaccinated patients with T2DM. A natural language processing algorithm was applied to identify people with and without diabetes. After 1:3 matching, we collected data for 6,829 patients with T2DM and 20,487 healthy controls. Multiple logistic regression analysis was used to calculate the odds ratio for severe AEs. @*Results@#After COVID-19 vaccination, patients with T2DM were more likely to experience eight severe AEs than controls: cerebral venous sinus thrombosis, encephalitis myelitis encephalomyelitis, Bell’s palsy, lymphadenopathy, ischemic stroke, deep vein thrombosis (DVT), thrombocytopenia (TP), and pulmonary embolism (PE). Moreover, patients with T2DM vaccinated with BNT162b2 and mRNA-1273 were more vulnerable to DVT and TP than those vaccinated with JNJ-78436735. Among patients with T2DM administered mRNA vaccines, mRNA-1273 was safer than BNT162b2 in terms of the risk of DVT and PE. @*Conclusion@#Careful monitoring of severe AEs in patients with T2DM may be necessary, especially for those related to thrombotic events and neurological dysfunctions after COVID-19 vaccination.
RESUMEN
Background and Objectives@#Recurrent epistaxis requiring emergency department (ED) visits results in increased morbidity in the elderly and associated with high health care costs. This study is to analyze the frequency and characteristics of epistaxis patients in the elderly and to find out the risk factors and effective treatment for recurrent epistaxis. Subjects and Method We studied retrospectively the clinical cases of 977 emergency patients and 155 patients, aged over 65, for the treatment of epistaxis during the last 10 years from January 2008 to January 2018. The group A, comprised of 95 patients (68.29%), was treated with an initial treatment. The group B, which comprised of 60 patients (38.71%), visited for re-bleeding following an initial treatment. @*Results@#Patients made 2 to 10 ED visits due to re-bleeding and 32 of the 60 patients (53.5%) visited twice. The electrocauterization was the most common (61.7%) for treatment method during rebleeding, followed by posterior packing (18.3%). The factors that increases the risk of recurrent epistaxis are anticoagulants, posterior epistaxis, anterior packing, inefficient ED packing. There was no correlation between comorbidities and rebleeding. @*Conclusion@#Accurate medical history taking of anticoagulants may enable personnel to provide more effective management of these patients. The most important factors in the failure of primary care were not being able to find the precise area of bleeding and ineffective packing during the initial treatment. Therefore, it is important that we must carefully check the areas using the endoscope to decrease the failure of initial treatment of epistaxis.
RESUMEN
Although surgery was the standard treatment for early gastrointestinal cancers, endoscopic resection is now a standard treatment for early gastrointestinal cancers without regional lymph node metastasis. High-definition white light endoscopy, chromoendoscopy, and image-enhanced endoscopy such as narrow band imaging are performed to assess the edge and depth of early gastrointestinal cancers for delineation of resection boundaries and prediction of the possibility of lymph node metastasis before the decision of endoscopic resection. Endoscopic mucosal resection and/or endoscopic submucosal dissection can be performed to remove early gastrointestinal cancers completely by en bloc fashion. Histopathological evaluation should be carefully made to investigate the presence of risk factors for lymph node metastasis such as depth of cancer invasion and lymphovascular invasion. Additional treatment such as radical surgery with regional lymphadenectomy should be considered if the endoscopically resected specimen shows risk factors for lymph node metastasis. This is the first Korean clinical practice guideline for endoscopic resection of early gastrointestinal cancer. This guideline was developed by using mainly de novo methods and encompasses endoscopic management of superficial esophageal squamous cell carcinoma, early gastric cancer, and early colorectal cancer. This guideline will be revised as new data on early gastrointestinal cancer are collected.

RESUMEN
Central skull base osteomyelitis (CSBO) is a rare, fatal condition seen mostly in elderly diabetic or immunocompromised patients; it mainly involves the sphenoid or occipital bones and diagnosis is often delayed. A 72-year-old male with diabetes was referred to our department with severe pain in the maxillary gingiva. Endoscopic biopsy of the pterygoid bone confirmed the presence of mucormycosis combined with Klebsiella pneumoniae infection. Sinus surgery was performed with bilateral alveolar bone sequestrectomy. Long-term intravenous broad-spectrum antibiotic therapy using meropenem and ampicillin/sulbactam and antifungal therapy using amphotericin B (100 mg/day) was administered; an oral antifungal agent, posaconazole (800 mg/day), was also prescribed for 11 weeks. At the 6-month follow-up visit, there were no complications and no progression of the CSBO lesion was observed. Timely diagnosis and multidisciplinary treatment including endoscopic surgery, alveolar bone sequestrectomy, and combined antifungal and antibiotic therapy can reduce mortality and minimize complications associated with CSBO.
RESUMEN
Purpose@#The purpose of this study was to provide high-quality rehabilitation nursing through the analysis of academic big data in domestic rehabilitation nursing and to provide basic data for preparing a plan for supporting families who perform rehabilitation nursing. @*Methods@#This study is a literature review to explore research trends in rehabilitation nursing. We collected quantitative and qualitative data in the educational and academic information database (RISS) defined as the big data, and extracted keywords by the 'rehabilitation', and 'rehabilitation nursing'. The data were analyzed by’R’ Program. Word cloud and social network analysis were performed. @*Results@#In the field of domestic rehabilitation nursing study, the main keywords were patient, stroke, family, old man, depression, stress, and quality of life. As a result of sentiment analysis with the main keywords in domestic rehabilitation nursing, negative emotional words appeared 6 times higher than positive emotional words. @*Conclusion@#We suggested that it is also necessary to prepare emotional support plans for patients, family and nurses who are targeted for rehabilitation nursing.
