PURPOSE: The aim of this study was to design optimized food intake patterns that meet the nutritional recommendations with minimal changes from the current food intake patterns among Korean adults using linear programming. METHODS: Data of a one day 24-hour dietary recall from the 2010~2014 Korea National Health and Nutrition Survey were used to quantify the food items that Korean adults usually consumed. These food items were categorized into seven groups and 24 subgroups. The mean intakes and intake distributions of the food groups and the food subgroups were calculated for eight age (19~29, 30~49, 50~64, and over 65 years old) and gender (male and female) groups. A linear programming model was constructed to minimize the difference between the optimized and mean intakes of the food subgroups while meeting the Dietary Reference Intakes for Koreans (KDRIs) for energy and 13 nutrients, and not exceeding the typical quantities of each food subgroup consumed by the respective age and gender groups. RESULTS: The optimized food intake patterns, which were a set of quantities of 24 food subgroups, were obtained mathematically for eight age and gender groups. Overall, major modifications of current diet were required to increase the intake of vegetables and milk/dairy products and decrease the Kimchi intake. The optimized intake of seasonings, including salt, was calculated to be 0 g for all the age and gender groups. CONCLUSION: The optimized food intake patterns designed using linear programming in this study lack feasibility because they suggest a seasoning consumption of 0 g. Modification of intake goal for sodium is needed to obtain optimized food intake patterns with improved feasibility.

Korean Journal of Community Nutrition 2020;25(3):204-213
Objectives:
This study examined the dietary characteristics and needs for community kitchens among young adults of single-person households in Seoul according to the cooking attitude.
Methods:
During April 2018, an online survey was conducted on young adults of singleperson households in their 20s and 30s residing in Seoul. The respondents were classified into the more positive cooking attitude group (More Positive Group; n=152, mean=4.11) and the less positive cooking attitude group (Less Positive Group; n=190, mean=3.03) based on the mean score (3.51) of the 4-item 5-point Likert scales measuring the cooking attitude. The responses of the two groups were compared.
Results:
Approximately 90% of the More Positive Group had the cooking ability to prepare ordinary meals or more advanced cooking skills, whereas only 61% of the Less Positive Group had such skills. Approximately a half of the More Positive Group cooked at home three times a week or more; only 30% of the Less Positive Group did so, and more than 30% of the group seldom cooked. The More Positive Group had higher mean scores in the levels of satisfaction with dietary life and care for food safety and nutrition than the Less Positive Group. Approximately 30% of all the respondents expressed their needs for community kitchens. The most frequently answered reason for such needs was “being able to have a meal with others”.
Conclusions
The young adults of single-person households with a more positive cooking attitude possessed a higher cooking ability, cooked more often, and cared more about food safety and nutrition than those with a less positive cooking attitude. There were moderate needs for community kitchens among young adults of single-person households living in Seoul. Therefore, societal efforts to improve their cooking attitude would be meaningful for improving their quality of dietary life. Cooking lessons or social dining programs based on community kitchens could be an option.

Large microbial communities reside in the gut as an endogenous organ and interact with the host physiology through symbiotic relationships, affecting health. Recent advances in high-throughput sequencing techniques have made it possible to better understand these complex microbial communities and their effects on hosts. Animal and clinical studies have provided considerable evidence to show that the microbiota plays an important role in chronic kidney disease, acute kidney injury, nephrolithiasis, and kidney transplantation by altering the functions of the intestinal barrier, regulating local and systemic inflammation, controlling production of metabolic components, and affecting immune responses. Although the exact mechanism underlying the microbial shift and its impact on disease progression remains uncertain, the kidney-gut interaction clearly plays a significant role in onset and progression of kidney disease and, therefore, holds promise as a therapeutic target. Here, we review recent literature pertaining to the bidirectional relationship between microbes and humans in various kidney diseases and discuss the future direction of microbial research in nephrology.

Purpose:
This study describes the development and implementation of a mechanical ventilation education program with a blended learning method for nursing students.
Methods:
Sixty-five nursing students were recruited either to the experimental group (n=33) or to the control group (n=32) in May 2020. This program was developed based on the analysis, design, development, implementation, and evaluation model. The analysis phase consisted of a literature review, expert consultations, and target group survey. In addition, learning objectives and a structure were designed, and an online program was developed. In the implementation phase, the program was conducted over the course of 2 weeks. The evaluation phase involved verification of the effects of the program on knowledge of mechanical ventilation, self-confidence, and ventilator nursing skills performance, as well as an assessment of satisfaction with the program.
Results:
The experimental group had significantly higher scores on knowledge of mechanical ventilation (t=4.29, p<.001), self-confidence (t=2.31, p=.024), and ventilator nursing skills performance (t=4.65, p<.001) than the control group.
Conclusion
The results indicate that this mechanical ventilation education program with blended learning was effective in meeting the needs of nursing students and can be widely used in this context.

Early postoperative anastomotic obstruction after colorectal surgery rarely develops. Herein, we present a case of a 50-year-old healthy woman who had an early postoperative anastomotic obstruction which was revealed caused by a blood clot and successfully managed by endoscopic approach. The patient was discharged after laparoscopic anterior resection and visited the emergency department one day after because of abdominal pain. Computed tomography showed that the anastomosis site was obstructed with low-density material. Intraoperative endoscopy was performed under general anesthesia and blood clot filling the lumen were identified. As the scope was advanced to the blood clot with air inflation, the blood clot was evacuated. The anastomosis site could be obstructed by blot clot with mucous debris albeit it is a rare condition. An endoscopic approach seems to be the first option in the diagnosis and treatment of postoperative obstruction at the anastomosis site and it could prevent unnecessary laparotomy.

Large fetal neck masses can cause life threatening airway obstructions after delivery. The ex utero intrapartum treatment (EXIT) can be used to obtain a fetal airway while feto-maternal circulation is preserved. The relationship of neck mass to airway structures can be defined prenatally with ultrasound and magnetic resonance imaging (MRI). We present a successful EXIT case in which prenatally a large fetal neck mass was diagnosed on ultrasound and MRI at 35 weeks of gestation in 30 year-old paturient.

PURPOSE: This study examined and compared the associations of the iron status and food intake with the blood lead, mercury, and cadmium concentrations among Korean adolescent girls, premenopausal women, and postmenopausal women. METHODS: The data from the 2010~2011 Korea National Health and Nutrition Examination Survey (KNHANES) was used. The subjects were classified into three groups: adolescent girls (n = 268), premenopausal women (n = 1,157), and postmenopausal women (n = 446). The iron status was assessed by hemoglobin, hematocrit, serum ferritin, and iron concentrations, as well as the total iron binding capacity (TIBC). The food intake was estimated by a food frequency questionnaire. RESULTS: The blood heavy metal concentrations and poisoning rate in postmenopausal women were higher than in the other groups. The iron status in the adolescent girls and postmenopausal women was higher than that in the premenopausal women. In the adolescent girls, the iron status was inversely associated with the blood cadmium concentration. The dairy food intake was inversely related to the blood lead and cadmium concentrations. In premenopausal women, the iron status was inversely associated with the cadmium concentrations. The fish and shellfish food intakes were positively associated with the mercury concentrations. In postmenopausal women, the iron status was positively associated with the mercury and cadmium concentrations. Fast foods and fried foods were inversely associated with the lead concentration. CONCLUSION: The premenopausal women showed a lower iron status than the adolescent girls and postmenopausal women. The associations of the iron status with the blood heavy metal concentrations were different among the adolescent girls, premenopausal women, and postmenopausal women. In addition, the relationships of the food intakes with the blood heavy metal concentrations differed among adolescent girls, premenopausal women, and postmenopausal women. Further studies will be needed to confirm these findings.

PURPOSE: A retrospective study was conducted to review the treatment and outcomes of mainly melanomas in acral location in a single institution in Korea, and to evaluate the prognostic significance of anatomic locations of the tumor. MATERIALS AND METHODS: A retrospective review was completed on 40 patients between 2001 and 2006 to obtain pertinent demographic data, tumor data, treatment characteristics, and follow-up data. RESULTS: Forty melanoma patients were identified and analyzed. Of these, 18 were male and 22 were female patients and the mean age at the time of diagnosis was 55.9 years. Of the tumors, 65% were located on the hands and feet with acral lentiginous melanoma being the most common histological subtype. Univariate analysis for the overall melanoma survival revealed that the thickness of the tumor and the clinical stage have prognostic significances. The most significant factor as analyzed by a multivariate analysis was shown to be the advanced clinical stage. Acral melanomas did not show statistically significant differences in the age at diagnosis, thickness of the tumor, stage, ulceration, and survival rates compared to non-acral melanomas. There was also no significant difference in the survival rate between the patients treated by amputation versus wide local excision in acral melanomas. CONCLUSION: In Korean melanoma patients, thickness and advanced stages are significant factors for poorer prognosis. However, the location of melanoma did not have a significant prognostic value. In treating the melanomas in acral location, local wide excisions resulted in a similar prognosis compared to amputations.
