OBJECTIVE: The mGluR1 (metabotropic glutamate receptor 1) gene, a G protein–coupled receptor, is known to mediate perceptions of umami tastes. Genetic variation in taste receptors may influence dietary intake, and in turn have an impact on nutritional status and risk of chronic disease. We investigated the association of mGluR1 rs2814863 polymorphism with lipid profiles and cardiovascular disease (CVD) risk, together with their modulation by macronutrient intake in Korean adults. METHODS: The subjects consisted of 8,380 Koreans aged 40-69 years participating in the Anseong and Ansan Cohort Study, which was a part of the Korean Genome Epidemiology Study (KoGES). Data was collected using self-administered questionnaires, anthropometric measurements, and blood chemical analysis. RESULTS: Carriers of C allele at mGluR1 rs2814863 was associated with decreased high density lipoprotein cholesterol (HDL-C) and increased triglyceride as compared to carriers of TT. Also, carriers of the C allele showed higher fat intake and lower carbohydrate intake than those with carriers of TT. After adjustment for multiple testing using false-discovery rate method, the significant difference of HDL-C, triglyceride, dietary fat, and carbohydrate across genotypes disappeared. Gene-diet interaction effects between rs2814863 and macronutrients intake were not significantly associated with HDL-C and triglyceride levels. However, carriers of C allele demonstrated significantly higher odds of CVD {odds ratio=1.13, 95% CI=1.02-1.25} compared with carriers of TT. CONCLUSIONS: Our findings support significant associations between the mGluR1 rs2814863 genotype and CVD-related variables in Korean adults. However, these associations are not modified by macronutrient intake.

Eosinophilic cellulitis is a rare, recurrent dermatosis which was first described by Wells in 1971. The etiology and pathogenesis of eosinophilic cellulitis are currently unknown, but a type IV hypersensitivity to various antigens followed by vascular damage seems to play a role in the pathogenesis of eosinophilic cellulitis. Most cases of eosinophilic cellulitis occur in adults. Only 29 cases have been reported in children. Generally, pediatric cases are recurrent but show good response to systemic steroids. We present a case of eosinophilic cellulitis in an 8-year-old boy. Who presented with acute onset of erythematous plaques on both thighs. These lesions were pruritic but not painful. A skin biopsy specimen showed dense mixed inflammatory infiltrations that consisted mostly of eosinophils, lymphocytes and histiocytes. Flame figures surrounded by eosinophils and histocytes and foci of degenerated collagen bundles were observed in the dermis. The lesions resolved rapidly after the initiation of oral steroid therapy. After 6 months, the patient has not experienced recurrence of the disease.

This study was conducted in order to investigate body awareness and dietary life according to gender. Subjects of the study were 120 men and 127 women aged 20 to 30 years, who exercise regularly at a fitness center in Seoul. The subjects were asked to fill out a questionnaire on body awareness, reason for regular exercise, dietary behaviors, and nutrition knowledge. The percentage of overweight and obesity was 69.2% in men, and 25.2% in women. The percentage of subjects who considered themselves as overweight was 38.3% in men and 59.8% in women. Intake of protein in men was higher than the recommended nutrient intake (RNI). Intake of energy in women was lower than the estimated energy requirement (EER). Men who considered themselves as overweight showed lower energy intake than men who considered their body weight as under and normal, whereas no difference in energy intake was observed between women who considered themselves as overweight and women who considered their body weight as under and normal.

Very rare and unique tumors of infants, fibrous hamartomas were first described by Reye in 1956 as a subdermal fibromatous tumor of infancy. The tumors can occur at birth and are usually diagnosed within the first 2 years of life. The oldest patient reported in the literature was an 11-year-old child. The common sites of involvement are the axillae, upper arms, and upper trunk. Although the lesion is not distinctive clinically, it has a characteristic microscopic appearance of fibrous tissue forming trabeculae, small, round cells that represent primitive mesenchyme, and mature adipose tissue. Herein, we report a case of fibrous hamartoma of infancy in a 26-year-old man, on the uncommon site of a lower extremity.

PURPOSE: Enteral feeding remains controversial in patients receiving extracorporeal membrane oxygenation (ECMO), particularly in those treated with a high-dose vasopressor. This study examined the safety and feasibility of enteral nutritional support for patients undergoing ECMO in a cardiac care unit (CCU). METHODS: Adult patients admitted to the CCU undergoing ECMO from January 2014 to May 2015 were included. Patients with <48 hours of support, undergoing ECMO at another hospital, and inaccurate medical records were excluded. RESULTS: Among the 14 patients undergoing ECMO in the CCU, 2 patients were diagnosed with malnutrition and the others were in the normal state in the initial assessment. On the other hand, they had the malnutrition risk factors (anorexia, weight loss, fluid retention, and hypermetabolic state). Thirteen patients received enteral nutrition and 1 patient had possible oral intake. The average initiation day of enteral nutrition was 2.0±1.6 days on ECMO. The mean duration of enteral nutrition was 5.2±4.9 days and the target goal was achieved within 3 days. There were no serious adverse effects for enteral nutrition but 3 patients had gastrointestinal problems (diarrhea and anorexia), and gastrointestinal bleeding occurred in 1 patient. In 1 case, enteral nutrition had to be stopped due to the prone position. Overall, 5 patients were cured, 3 patients recovered through heart transplantation, and 6 patients died. CONCLUSION: Most CCU patients receiving ECMO were well nourished but had the malnutrition risk factors in progress. These results suggest that enteral feeding might be safe and feasible in patients treated with ECMO but there were minor side effects.

Purpose: The purpose of this study was to reveal the clinicopathological characteristics and prognostic implications associated with fibroblast growth factor receptor 1 (FGFR1) amplification in colorectal cancers (CRCs). Materials and Methods: We measured the copy number of FGFR1 by droplet digital polymerase chain reaction (ddPCR), and analyzed the FGFR1 expression by immunohistochemistry, in 764 surgically resected CRCs (SNUH2007 dataset, 384 CRCs; SNUH Folfox dataset, 380 CRCs). Results: CRCs with ≥ 3.3 copies of the FGFR1 gene were classified as FGFR1 amplified. FGFR1 amplification was found in 10 of the 384 CRCs (2.6%) in the SNUH2007 dataset, and in 28 of the 380 CRCs (7.4%) in the SNUH Folfox dataset. In the SNUH2007 dataset, there was no association between the FGFR1 copy number status and sex, gross appearance, stage, or differentiation. High FGFR1 expression was associated with female sex and KRAS mutation. At the molecular level, FGFR1 amplification was mutually exclusive with BRAF mutation, microsatellite instability, and MLH1 methylation, in both SNUH2007 and SNUH Folfox datasets. Survival analysis revealed that FGFR1 amplification was associated with significantly worse clinical outcome compared with no FGFR1 amplification, in both SNUH2007 and SNUH Folfox datasets. Within the SNUH2007 dataset, CRC patients with high FGFR1 expression had an inferior progression-free survival compared with those with low FGFR1 expression. The FGFR inhibitor, PD173074, repressed the proliferation of a CRC cell line overexpressing FGFR1, but not of cells with FGFR1 amplification. Conclusion FGFR1 amplification measured by ddPCR can be a prognostic indicator of poor clinical outcome in patients with CRCs.

The first edition of ‘A Standardized Pathology Report for Gastric Cancer’ was initiated by the Gastrointestinal Pathology Study Group of the Korean Society of Pathologists and published 17 years ago. Since then, significant advances have been made in the pathologic diagnosis, molecular genetics, and management of gastric cancer (GC). To reflect those changes, a committee for publishing a second edition of the report was formed within the Gastrointestinal Pathology Study Group of the Korean Society of Pathologists. This second edition consists of two parts: standard data elements and conditional data elements.The standard data elements contain the basic pathologic findings and items necessary to predict the prognosis of GC patients, and they are adequate for routine surgical pathology service. Other diagnostic and prognostic factors relevant to adjuvant therapy, including molecular biomarkers, are classified as conditional data elements to allow each pathologist to selectively choose items appropriate to the environment in their institution. We trust that the standardized pathology report will be helpful for GC diagnosis and facilitate large-scale multidisciplinary collaborative studies.

Gastric cancer is one of the most common cancers in Korea and the world. Since 2004, this is the 4th gastric cancer guideline published in Korea which is the revised version of previous evidence-based approach in 2018. Current guideline is a collaborative work of the interdisciplinary working group including experts in the field of gastric surgery, gastroenterology, endoscopy, medical oncology, abdominal radiology, pathology, nuclear medicine, radiation oncology and guideline development methodology. Total of 33 key questions were updated or proposed after a collaborative review by the working group and 40 statements were developed according to the systematic review using the MEDLINE, Embase, Cochrane Library and KoreaMed database. The level of evidence and the grading of recommendations were categorized according to the Grading of Recommendations, Assessment, Development and Evaluation proposition. Evidence level, benefit, harm, and clinical applicability was considered as the significant factors for recommendation. The working group reviewed recommendations and discussed for consensus. In the earlier part, general consideration discusses screening, diagnosis and staging of endoscopy, pathology, radiology, and nuclear medicine. Flowchart is depicted with statements which is supported by meta-analysis and references. Since clinical trial and systematic review was not suitable for postoperative oncologic and nutritional follow-up, working group agreed to conduct a nationwide survey investigating the clinical practice of all tertiary or general hospitals in Korea. The purpose of this survey was to provide baseline information on follow up. Herein we present a multidisciplinary-evidence based gastric cancer guideline.
