Meal Service and Nutritional Management for Dysphagia: A Nationwide Hospital Survey / 대한연하장애학회지

Objective@#This study enrolls diverse hospitals and analyzes the differences in meal provision and nutrition management services for patients with dysphagia. @*Methods@#A nationwide survey was conducted by mail and mobile for 850 medical institutions, and data were collected from 217 hospitals. We analyzed the status of the dysphagia diet and nutrition management by considering the type of hospital. @*Results@#Among the hospitals surveyed, 167 (77%) provided texture-modified diets for dysphagia patients. The status of providing dysphagia diets and nutrition management for dysphagia differed depending on the institution. In particular, nutrition services for dysphagia patients in long-term care hospitals were poor. Difficulties in providing a dysphagia diet included the complexity of the cooking process, difficulty maintaining constant viscosity, difficulty in hygiene management, and low meal bills. Using commercial thickeners in cooking accounted for 72.5%, and only 41.9% of hospitals provided a commercial thickener with meals. Compared to the regular diet, the additional food cost to provide a single dysphagia diet meal was estimated to be 500-1,000 won. Based on a 5-point scale, we determined that the average scores for the importance and performance of nutrition management in patients with dysphagia were 4.29 and 3.19 points, respectively. Regardless of the type of hospital, performances of all the steps in the nutrition care process were significantly lower than their importance. @*Conclusion@#Several difficulties are encountered in meal provision and nutrition management for patients with dysphagia, including the burden of expenses and human resources. Thus, the medical fees for a dysphagia diet need to be reasonably increased. Moreover, national health insurance should additionally cover nutrition education for dysphagia patients.

A Position Statement of the Utilization and Support Status of Continuous Glucose Monitoring in Korea / 임상당뇨병

The accuracy and convenience of continuous glucose monitoring (CGM), which efficiently evaluates glycemic variability and hypoglycemia, are improving. There are two types of CGM: professional CGM and personal CGM. Personal CGM is subdivided into real-time CGM (rt-CGM) and intermittently scanned CGM (isCGM). CGM is being emphasized in both domestic and foreign diabetes management guidelines. Regardless of age or type of diabetes, CGM is useful for diabetic patients undergoing multiple insulin injection therapy or using an insulin pump. rt-CGM is recommended for all adults with type 1 diabetes (T1D), and can also be used in type 2 diabetes (T2D) treatments using multiple insulin injections. In some cases, short-term or intermittent use of CGM may be helpful for patients with T2D who use insulin therapy other than multiple insulin injections and/or oral hypoglycemic agents. CGM can help to achieve A1C targets in diabetes patients during pregnancy. CGM is a safe and cost-effective alternative to self-monitoring blood glucose in T1D and some T2D patients. CGM used in diabetes management works optimally with proper education, training, and follow up. To achieve the activation of CGM and its associated benefits, it is necessary to secure sufficient repetitive training and time for data analysis, management, and education. Various supports such as compensation, insurance coverage expansion, and reimbursement are required to increase the effectiveness of CGM while considering the scale of benefit recipients, policy priorities, and financial requirements.

Dietary Assessment of Korean Non-dialysis Chronic Kidney Disease Patients with or without Diabetes

Background@#Dietary intervention at the early stage of chronic kidney disease (CKD) is important for preventing progression to the end-stage renal disease (ESRD). However, few studies have investigated dietary intake of CKD patients in non-dialysis stage. Therefore, we investigated the dietary intake of Korean non-dialysis CKD patients and aimed to establish baseline data for the development of dietary education and intervention strategies for CKD patients. @*Methods@#Three hundred fifty CKD patients who visited Seoul National University Hospital outpatient clinic from February 2016 to January 2017 were recruited for this cross-sectional study. Subjects on dialysis and those who had undergone kidney transplantation were excluded. Dietary intake, demographic information, and biochemical characteristics of 256 subjects who completed three-day dietary records were analyzed. Subjects were divided into four groups based on diabetes mellitus (DM) (DM-CKD and Non-DM-CKD groups) and kidney function (Early-CKD and Late-CKD groups). @*Results@#Total energy intake was lower in the Late-CKD group compared with the Early-CKD group. In men, carbohydrate intake was higher and protein and fat intakes tended to be lower in the Late-CKD group compared with the Early-CKD group. In women, carbohydrate intake tended to be lower in the DM-CKD group than the Non-DM-CKD group. Protein intake tended to be higher in the DM-CKD groups. Phosphorus and sodium intakes were higher in the DM-CKD groups compared with the Non-DM-CKD groups in women, and tended to be higher in the DM-CKD groups in men. @*Conclusion@#DM and kidney function affected energy and nutrient intakes. Subjects in the Late-CKD group consumed less energy than those in the Early-CKD group. Non-DM subjects seemed to restrict protein intake starting from the Early-CKD stage than subjects with DM. Subjects in this study had low energy and high sodium intakes compared with recommended levels. Protein intake was lower in advanced CKD patients, but their intake level was still higher than the recommendation. Dietary intervention strategies for non-dialysis CKD patients need to be customized depending on the presence of DM and kidney function.

Revision of an iodine database for Korean foods and evaluation of dietary iodine and urinary iodine in Korean adults using 2013–2015 Korea National Health and Nutrition Examination Survey / 한국영양학회지

Purpose@#Variations in the iodine contents of foods is critical for estimating the iodine intake. This study aimed to update the iodine database of common Korean foods and evaluated the iodine intake in Korean adults. @*Methods@#A list of 855 Korean foods was selected for the updated iodine database. The updated database was established with Version 1 and 2 by applying an average or minimum value for the imputed values. The iodine intake was estimated in 5,927 Korean adults using the data from the 2013–2015 Korea National Health and Nutrition Examination Survey. @*Results@#The analytical values in the updated database were 166 (19.4%), followed in order by 318 (37.2%), 247 (28.9%), and 124 (14.5%) for the adapted, imputed, and missing values, respectively. The median of dietary iodine intake was 352.1 μg/day (± 2,166.1) and 343.4 μg/day (± 2,161.9) in Version 1 and 2 among the total population. The contribution rates of each food group to the iodine intake were 55.7% for seaweeds, which showed a similar trend in Version 2. When subjects were divided by consumption of seaweeds, the median iodine intake was 495.7 μg in the consumer group, which was almost double (241.2 μg) that of the non-consumer group. The proportion of subjects who consumed below the Estimated Average Requirement of iodine was 11.0% in the non-consumer group. In contrast, 11.6% in the consumer group of seaweed consumed above the Upper Level of iodine. When the dietary iodine and urinary iodine were examined, the regression coefficient was 0.11718 in Version 1 and 0.11512 in Version 2 after adjusting for age and sex. @*Conclusion@#This study presented the variation of iodine intake in Korean adults by applying different versions of the iodine database. As the iodine intake can vary due to the highly variable concentrations in the major food sources, an iodine database is necessary to be monitored, and caution should be taken when the database is used in research.

Effects of Maternal Iodine Status during Pregnancy and Lactation on Maternal Thyroid Function and Offspring Growth and Development: A Prospective Study Protocol for the Ideal Breast Milk Cohort

BACKGROUND: Iodine is an intrinsic element of thyroid hormone, which is essential for childhood growth and development. The Ideal Breast Milk (IBM) cohort study aims to evaluate the effects of maternal iodine status during pregnancy and lactation on maternal thyroid function, offspring growth and development, and offspring thyroid function. METHODS: The IBM cohort study recruited pregnant women from Seoul National University Hospital between June 2016 and August 2017, followed by enrollment of their offspring after delivery. For the maternal participants, iodine status is evaluated by urinary iodine concentration (UIC) and dietary records in the third trimester and at 3 to 4 weeks and 12 to 15 months postpartum. For the child participants, cord blood sampling and UIC measurements are performed at birth. At 3 to 4 weeks of age, UIC and breastmilk iodine concentrations are measured. At 12 to 15 months of age, growth and development are assessed and measurements of UIC, a thyroid function test, and ultrasonography are performed. RESULTS: A total of 198 pregnant women in their third trimester were recruited. Their mean age was 35.1±3.5 years, and 78 (39.4%) of them were pregnant with twins. Thirty-three (16.7%) of them had a previous history of thyroid disease. CONCLUSION: Korea is an iodine-replete area. In particular, lactating women in Korea are commonly exposed to excess iodine due to the traditional practice of consuming brown seaweed soup postpartum. The study of the IBM cohort is expected to contribute to developing guidelines for optimal iodine nutrition in pregnant or lactating women.

Applicability Evaluation of Job Standards for Diabetes Nutritional Management by Clinical Dietitian

This study was conducted to evaluate applicability of job standards for diabetes nutrition management by hospital clinical dietitians. In order to promote the clinical nutrition services, it is necessary to present job standards of clinical dietitian and to actively apply these standardized tasks to the medical institution sites. The job standard of clinical dietitians for diabetic nutrition management was distributed to hospitals over 300 beds. Questionnaire was collected from 96 clinical dietitians of 40 tertiary hospitals, 47 general hospitals, and 9 hospitals. Based on each 5-point scale, the importance of overall duty was 4.4 ± 0.5, performance was 3.6 ± 0.8, and difficulty was 3.1 ± 0.7. ‘Nutrition intervention’ was 4.5 ± 0.5 for task importance, ‘nutrition assessment’ was 4.0 ± 0.7 for performance, and ‘nutrition diagnosis’ was 3.4 ± 0.9 for difficulty. These 3 items were high in each category. Based on the grid diagram, the tasks of both high importance and high performance were ‘checking basic information,’‘checking medical history and therapy plan,’‘decision of nutritional needs,’‘supply of foods and nutrients,’ and ‘education of nutrition and self-management.’ The tasks with high importance but low performance were ‘derivation of nutrition diagnosis,’‘planning of nutrition intervention,’‘monitoring of nutrition intervention process.’ The tasks of both high importance and high difficulty were ‘derivation of nutrition diagnosis,’‘planning of nutrition intervention,’‘supply of foods and nutrients,’‘education of nutrition and self-management,’ and ‘monitoring of nutrition intervention process.’ The tasks of both high performance and high difficulty were ‘documentation of nutrition assessment,’‘supply of foods and nutrients,’ and ‘education of nutrition and self-management.’

Intensive Nutrition Management in a Patient with Short Bowel Syndrome Who Underwent Bariatric Surgery

Many individuals with short bowel syndrome (SBS) require long-term parenteral nutrition (PN) to maintain adequate nutritional status. Herein, we report a successful intestinal adaptation of a patient with SBS through 13 times intensive nutritional support team (NST) managements. A thirty-five-year-old woman who could not eat due to intestinal discontinuity visited Seoul National University Hospital for reconstruction of the bowel. She received laparoscopic Roux-en-Y gastric bypass (RYGB) due to morbid obesity in Jan 2013 at a certain hospital and successfully reduced her weight from 110 kg to 68 kg. However, after a delivery of the second baby by cesarean section in Jul 2016, most of small bowel was herniated through Peterson’s defect, and emergent massive small bowel resection was performed. Thereafter, she visited our hospital for the purpose of intestinal reconstruction. In Sep 2016, she received side–to-side gastrogastrostomy and revision of double barrel enterostomy. The remaining small bowel included whole duodenum, 30 cm of proximal jejunum, and 10 cm of terminal ileum. Pylorus and ileocecal valves were intact. The patient given only PN after surgery was provided rice-based soft fluid diet after 10 day of operation. Through intensive nutritional management care, she could start solid meals, and finally stop the PN and eat only orally at 45 days postoperatively. Three nutritional interventions were conducted over 2 months after the patient was discharged. She did not require PN during this period, and maintained her weight within the normal weight range. Similar interventions could be used for other patients with malabsorption problems similar to SBS.

In-depth Medical Nutrition Therapy for a Woman with Diabetes: From Pregnancy to Delivery

Diabetes in pregnancy is associated with higher rates of miscarriage, pre-eclampsia, preterm labor, and fetal malformation. To prevent these obstetric and perinatal complications, women with diabetes have to control levels of blood sugar, both prior to and during pregnancy. Thus, individualized medical nutrition therapy for each stage of pregnancy is essential. We provided in-depth medical nutrition therapy to a 38-year-old pregnant woman with diabetes at all stages of pregnancy up to delivery. She underwent radiation therapy after surgery for breast cancer and was diagnosed with diabetes. At the time of diagnosis, her glycated hemoglobin level was 8.3% and she was planning her pregnancy. She started taking an oral hypoglycemic agent and received education regarding the management of diabetes and preconception care. She became pregnant while maintaining a glycated hemoglobin level of less than 6%. We provided education program for diabetes management during the pregnancy, together with insulin therapy. She experienced weight loss and ketones were detected; furthermore, she was taking in less than the recommended amount of foods for the regulation of blood sugar levels. By giving emotional support, we continued the counseling and achieved not only glycemic control but also instilled an appreciation of the importance of appropriate weight gain and coping with difficulties. Through careful diabetes management, the woman had a successful outcome for her pregnancy, other than entering preterm labor at 34 weeks. This study implicated that the important things in medical nutrition therapy for pregnant women with diabetes are frequent follow-up care and emotional approach through the pregnancy process.

Nutritional Screening Tool for In-Hospital Patients

Malnutrition is a common problem in hospital settings. A poor nutritional status has been associated with higher rates of infection, poor wound healing, longer hospital stays, and higher hospital costs. Therefore, early recognition and timely treatment of malnutrition is vital. To identify malnourished individuals or those at risk of becoming malnourished, selecting and validated a uniform screening tool is clearly an important issue. Both the Nutritional Risk Screening-2002 (NRS-2002) and Malnutrition Universal Screening Tool (MUST) are recommended by the European Society for Parenteral and Enteral Nutrition (ESPEN) for a hospital setting. For older patients, the Mini Nutritional Assessment (MNA) is the recommended tool. Short Nutrition Assessment Questionnaire (SNAQ) and Malnutrition Screening Tools (MST) are brief and simple screening tools that use self-reported queries of variables that include weight loss and poor appetite. On the other hand, many of those require considerable time and labor to administer and may not be highly applicable to a Korean population. In Korea, most hospitals use a computerized nutritional screening system with a self-developed nutrition screening index. The variables for the tools, which are based on each hospital setting, include the objective data available in the patient's medical records and limited information collected from the nursing admission questionnaire. The application of different tools hampers any comparison of the malnutrition prevalence between different settings and patients groups. In addition, the absence of a widely accepted malnutrition screening tool hinders both effective recognition and the treatment of malnutrition. Therefore, the development of uniform and valid screening tools and effective nutritional support programs for Korean malnourished patients is needed.

Characteristics and Clinical Course of Patients Who Received Enteral or Parenteral Nutrition in Tertiary Referral Hospitals in Korea

PURPOSE: The purposes of this study are to evaluate clinical characteristics of malnourished patients who received nutritional therapy and to compare their clinical courses according to nutritional support team (NST) consultation in tertiary referral hospital in Korea. METHODS: From June 2014 to May 2015, 43,954 admitted patients who were more than 18 years old were retrospectively investigated. Characteristics of patients who received enteral nutrition (EN) or parenteral nutrition (PN) for more than 3 days (nutritional therapy group) were compared to the patients without nutritional therapy (control group). In addition, clinical courses according to NST consultation (NST group and non-NST group) were compared through propensity score matching (PSM). RESULTS: EN or PN was applied in 4,599 patients for more than 3 days (nutritional therapy group: 10.5%). For characteristics, there were significant differences between two groups (nutritional therapy group vs. control group) with age, male proportion, body weight, body mass index. All laboratory data at admission were significantly worse in nutritional therapy group. And for clinical courses, there were significant differences in length of stay (LOS), rate of intensive care unit (ICU) admission, LOS in ICU, Acute Physiology and Chronic Health Enquiry (APACHE II) score, days of nutritional therapy, mortality rate. NST consultation was made in 39% of nutritional therapy group. Among departments, Thoracic Surgery showed the highest rate of NST consultation (68.5%) otherwise Neurosurgery showed the lowest rate (18.7%). When PSM between NST group vs. non-NST group were made, significant differences was shown only in the rate of ICU admission, EN or PN support days, cholesterol at discharge. CONCLUSION: In tertiary referral hospital in Korea, more than 10% of patients still needed active nutritional therapy. NST consultation rate varies among departments. We failed to find significant differences between NST group and non-NST group.

Dietary evaluation of a low-iodine diet in Korean thyroid cancer patients preparing for radioactive iodine therapy in an iodine-rich region

BACKGROUND/OBJECTIVES: Despite the importance of a low-iodine diet (LID) for thyroid cancer patients preparing for radioactive iodine (RAI) therapy, few studies have evaluated dietary intake during LID. This study evaluated the amount of dietary iodine intake and its major food sources during a typical diet and during LID periods for thyroid cancer patients preparing for RAI therapy, and examined how the type of nutrition education of LID affects iodine intake. SUBJECTS/METHODS: A total of 92 differentiated thyroid cancer patients with total thyroidectomy were enrolled from Seoul National University Hospital. All subjects completed three days of dietary records during usual and low-iodine diets before 131I administration. RESULTS: The median iodine intake was 290 µg/day on the usual diet and 63.2 µg/day on the LID. The major food groups during the usual diet were seaweed, salted vegetables, fish, milk, and dairy products and the consumption of these foods decreased significantly during LID. The mean energy intake on the LID was 1,325 kcal, which was 446 kcal lower than on the usual diet (1,771 kcal). By avoiding iodine, the intake of most other nutrients, including sodium, was significantly reduced during LID (P < 0.005). Regarding nutritional education, intensive education was more effective than a simple education at reducing iodine intake. CONCLUSION: Iodine intake for thyroid cancer patients was significantly reduced during LID and was within the recommended amount. However, the intake of most other nutrients and calories was also reduced. Future studies are needed to develop a practical dietary protocol for a LID in Korean patients.

The Efficacy and Safety of Non-Nutritive Sweeteners / 임상당뇨병

High intake of added sugars increases the risk for obesity, type 2 diabetes, and cardiovascular disease. Non-nutritive sweeteners (NNS) are widely used in many beverages and food products to reduce calories and sugar content. NNS have higher intensity of sweetness per gram than caloric sweeteners such as sucrose, corn syrup, and fruit juice concentrates. NNS approved for use have been tested and determined to be safe at levels that are within acceptable daily intake by the Joint Food Agriculture Organization/World Health Organization Expert Committee on Food Additives. The eight items of sweeteners are regulated as food additives in Korea. Dietary intake of the sweeteners was suggested as safety level by the ministry of Food and Drug Safety in 2012. If substituted for caloric sweeteners without intake of additional calories from other food sources, NNS may help consumers limit carbohydrate and energy intake as a strategy to manage blood glucose and weight. Dietitians can provide guidance on the use of NNS that give the desired results in food preparation and use at the table.

Development of Job Standards of Clinical Dietitian for the Clinical Nutrition Therapy to Cancer Patients in Hospitals

The present study was conducted to provide the basis for improvement of clinical nutrition services through development of job standards of clinical dietitian for the clinical nutrition therapy to cancer patients in hospitals. Developing A Curriculum (DACUM) method was used for job analysis and development of job standards for clinical dietitians for cancer care. Based on DACUM analysis, information about duties, tasks, and task elements of clinical dietitians for cancer care was collected. Developed job standards were applied to clinical nutrition care for cancer patients in hospitals for evaluation. Based on DACUM analysis, consultations from professionals, and field application tests, the final job standards were composed of four duties, 18 tasks, and 56 task elements. The duties consisted of nutritional assessment, nutrition diagnosis, nutrition intervention, and nutrition monitoring.evaluation. For cancer nutrition care, 109 work activities were developed. They were composed of 75 basic and 34 recommended work activities. The application of developed job standards for clinical dietitians for cancer care at 10 hospitals showed a performance rate of 72.3%. In conclusion, job standards for clinical dietitians for cancer care developed in this study might be effectively used as guidelines for providing clinical nutrition services for cancer patients in hospitals.

The Impact of Low Adherence to the Low-iodine Diet on the Efficacy of the Radioactive Iodine Ablation Therapy

To improve the efficacy of radioactive iodine (RAI) therapy for differentiated thyroid cancer patients, a low-iodine diet (LID) prior to the therapy is recommended. In iodine-rich areas such as Korea, however, a strict LID is very difficult to maintain. We experienced the cases of three patients showing low adherence to the LID before initial RAI therapy, and analyzed the main food source supplying iodine during the LID, and examined the influence of the poorly maintained LID on the efficacy of RAI therapy. The dietary intake during the LID periods were assessed using three-day dietary records and remnant thyroid activity after the second RAI administration was also evaluated. All patients' mean daily iodine intake during two-week LID periods exceeded the 100 microg guideline set by the Korean Thyroid Association (median 110.9 microg, ranges 100.4-117.0 microg). Although the typical food sources of iodine intake are seaweeds in Korea, salted vegetables were the main contributor to the patients' iodine intake during the LID periods. Remnant thyroid activity was shown on a follow-up scan in all of 3 patients suggesting low efficacy of RAI therapy. In summary, the patients with low adherence to the LID guideline showed unsuccessful remnant ablation, and the main food source of iodine was salted vegetables. Further studies are necessary to examine the relationship between adherence of the LID and RAI efficacy according to dietary iodine intake levels, as well as food sources that cause low adherence to the LID. These data can then be used to develop more practical LID guidelines.

Development of Job Standards for Clinical Nutrition Therapy for Dyslipidemia Patients

Dyslipidemia has significantly contributed to the increase of death and morbidity rates related to cardiovascular diseases. Clinical nutrition service provided by dietitians has been reported to have a positive effect on relief of medical symptoms or reducing the further medical costs. However, there is a lack of researches to identify key competencies and job standard for clinical dietitians to care patients with dyslipidemia. Therefore, the purpose of this study was to analyze the job components of clinical dietitian and develop the standard for professional practice to provide effective nutrition management for dyslipidemia patients. The current status of clinical nutrition therapy for dyslipidemia patients in hospitals with 300 or more beds was studied. After duty tasks and task elements of nutrition care process for dyslipidemia clinical dietitians were developed by developing a curriculum (DACUM) analysis method. The developed job standards were pretested in order to evaluate job performance, difficulty, and job standards. As a result, the job standard included four jobs, 18 tasks, and 53 task elements, and specific job description includes 73 basic services and 26 recommended services. When clinical dietitians managing dyslipidemia patients performed their practice according to this job standard for 30 patients the job performance rate was 68.3%. Therefore, the job standards of clinical dietitians for clinical nutrition service for dyslipidemia patients proposed in this study can be effectively used by hospitals.

Development of Job Standards for Clinical Dietitians Administering Clinical Nutrition Therapy to Diabetic Patients in Hospitals

This study was conducted to develop job standards for clinical dietitian administering clinical nutrition therapy to diabetic patients in hospitals. Based on DACUM (Developing A Curriculum) analysis of 17 members including clinical dietitians, professors majoring in clinical nutrition and researchers, information on duties, tasks and task elements of clinical dietitians for diabetes care were derived and applied to diabetes mellitus-specific clinical nutrition care in hospitals for evaluation. The final developed job standards for clinical dietitians for diabetes care included four duties, 19 tasks and 56 task elements. The duties consisted of nutrition assessment, nutrition diagnosis, nutrition intervention, and nutrition monitoring . evaluation. For application of diabetes mellitus-specific job standards in clinical nutrition care, 108 work activities were developed and classified into 90 basic and 18 recommended types. Performance rates of standardized jobs were 80.2% at nutrition assessment, 99.6% at nutrition diagnosis, 78.5% at nutrition intervention, and 32.9% at nutrition monitoring . evaluation. These results can be applied as guidelines to implement jobs for diabetes mellitus-specific clinical nutrition services in clinical settings. In addition, they would be useful for education standards in educational institutions for education and training of clinical dietitian.

An Iodine Database for Common Korean Foods and the Association between Iodine Intake and Thyroid Disease in Korean Adults

BACKGROUND AND OBJECTIVES: Iodine is essential for thyroid hormone production and the iodine intake of Koreans is high. Few studies have examined the association between iodine intake and thyroid disease in the Korean population due to the lack of an iodine database. Therefore, this study established an iodine database, evaluated iodine intake levels, and explored the association between iodine intake and thyroid disease. MATERIALS AND METHODS: We obtained data for 9998 subjects who had both biochemical and dietary data from the 2007-2009 Korea National Health and Nutrition Examination Survey. RESULTS: An iodine database was established for 667 food items. The median iodine intake in the population was 375.4 microg per day. The iodine contribution by food group was 65.6% from seaweed, 18.0% from salted vegetables, and 4.8% from fish. When subjects were divided into five groups across quintiles of iodine intake per 1000 kcal, excluding extreme subjects who consumed above the upper limit, age, sex, income, education, drinking, and smoking differed across the groups. While the energy and fat intakes decreased, other nutrients increased across the quintile groups. The consumption of seaweeds, fish, eggs, and salted vegetables increased across the quintile groups. After adjusting for all potential confounding variables, the odds ratio for thyroid disease in the highest quintile was 1.63 compared to that in the lowest quintile (p for trend=0.0352). CONCLUSION: The iodine intake of the Korean population is high, with high consumption of seaweeds, salted vegetables, and fish positively associated with thyroid disease.

A Prospective Observational Study Evaluating the Change of Nutritional Status and the Incidence of Dumping Syndrome after Gastrectomy

PURPOSE: The aim of this study was to investigate the change of nutritional status and the incidence of dumping syndrome after gastrectomy for gastric cancer. METHODS: From January 2013 to May 2014, 36 patients who underwent gastrectomy for gastric cancer were prospectively investigated in terms of nutritional status by body weight, anthropometric measurements, biochemical data, and Patient-Generated Subjective Global Assessment (PG-SGA). Dumping syndrome was assessed using a newly developed questionnaire based on the Japanese Society of Gastroenterological Surgery survey and Sigstad's scoring system. RESULTS: Body weight losses were 4.6%, 8.1%, and 6.9% at discharge, six months, and one year after discharge, respectively. Triceps skinfold thickness had no significance, however, mid-arm muscle circumference showed significant loss after gastrectomy. A part of the biochemical data showed significant change after gastrectomy, but almost indicated a restoring tendency within two months after discharge. In terms of PG-SGA, 33 patients (91.7%) were classified as A (well-nourished) before surgery, however, the number of well-nourished patients showed a sharp decrease to 1 (2.8%) at two weeks after discharge, and then gradually increased to 25 (69.4%) at one year. The main obstacles against diet intake were reported as 'early satiety' and 'anxiety'. The number of patients who had experience in at least one dumping syndrome related symptom was 21 (58.3%) at discharge, 26 (72.2%) at two months after discharge, and 11 (30.6%) at one year after discharge. CONCLUSION: Nutritional deficit as well as dumping syndrome is encountered in a large number of gastric cancer patients after gastrectomy. Postoperative nutritional support and personalized education seem to be very important during the postoperative period.

Nutritional Considerations for Diabetic Patients on Diabetes Medication / 임상당뇨병

Individuals who have diabetes should receive individualized medical nutrition therapy (MNT) based on an assessment of the individual's current eating patterns, preferences, and metabolic goals. The dietician should be able to coordinate food choices with the type of diabetes medicine being taken. Knowledge of the actions, side effects, and contraindication of diabetes medicine can help the dietician coordinate appropriate MNT and physical activity, to assist the individual with diabetes to achieve optimal glycemic control without unwanted effects. Carbohydrate consistency is important for diabetic patients on oral diabetes medications. The primary side effects with initial treatment of biguanides, alpha-glucosidase inhibitors, and incretin mimetics include gastrointestinal discomfort, which can be minimized by taking the medication with food, starting at a low dosage, and increasing the dosage slowly. Common side effects from use of insulin and insulin secretagogues (sulfonylureas and meglitinides) are hypoglycemia and weight gain. Consistent meal times and carbohydrate consistency are important to reduce risk of hypoglycemia. Energy restriction, reduced fat intake, regular physical activity, and avoidance of frequent hypoglycemia can be beneficial in preventing or limiting weight gain. The insulin regimen should be fitted to the meal plan and adjusted over time based on the results of blood glucose monitoring.

Early Postoperative 24-Hour Continuous Jejunostomy Feeding in Esophagectomy Patients

Esophagectomy can result in various postoperative nutrition-related complications that may impair the nutritional status of the patient. In our institution, we usually initiate 16-hour continuous jejunostomy feeding using an enteral feeding pump on postoperative day 2 as a routine protocol after esophagectomy. The target calorie intake was achieved in 6-7 days with this protocol, which is longer than that required with other recently reported feeding protocols. Accordingly, early jejunostomy feeding protocol, which starts on postoperative day 1 and continues for 24 hours was attempted. In the present report, we described 3 cases of early 24-hour continuous jejunostomy feeding after esophagectomy. The use of this new protocol reduced the duration required to achieve the target calorie intake as less than 5 days without any enteral feeding-related complications.
