OBJECTIVE: The primary objective of this study was to examine the validity and reliability of a semi-quantitative food frequency questionnaire (FFQ) among Chinese children aged 12-17 years. METHODS: A semi-quantitative 72-food item FFQ was developed for children aged 12-17 years. The reliability and validity of this FFQ were evaluated against 24-h dietary recalls (24 h DRs) to measure the consumption of foods and nutrients. We administered two FFQs and three DRs to children (N = 160) over a period of 1 month to evaluate the reliability and validity. Reliability was examined by quartile agreement and intraclass correlation coefficients (ICCs), and validity was examined by quartile agreement, Bland-Altman plots and correlation with DRs. RESULTS: For reliability, the ICCs between the two FFQs ranged from 0.21 to 0.76 for foods and nutrients, and the quartile agreement ranged from 70.0% to 95.0% in the same or adjacent quartiles. Spearman's correlation coefficients of foods and nutrients between the second FFQ and the 24 h DRs ranged from -0.04 to 0.59. The Bland-Altman plots demonstrated good agreement across the range of intakes among nutrients. The quartile agreement ranged from 50.0% to 100.0%, with infrequent misclassification. CONCLUSION The FFQ assessment of dietary intakes demonstrated acceptable relative validity and high reproducibility for Chinese children aged 12-17 years.

BACKGROUND/OBJECTIVES: This study investigated nutritional status of the elderly with dementia in a care facility with the aim of improving the meal quality of the facility. SUBJECTS/METHODS: Data were collected from 30 dementia patients aged more than 65 years in a long-term care facility in Hongseong. The data were obtained from questionnaires and medical records. The food intake data was obtained using food photographs and the nutrient intakes were calculated using the CAN-Pro 5.0. The data were compared with the dietary reference intakes for Koreans (KDRIs). The nutrient density, diet quality such as nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ), as well as dietary diversity score (DDS) were evaluated. The data were analyzed using SPSS statistical programs. RESULTS: The average daily energy intakes for men and women were much lower than the estimated energy requirements of the KDRIs. The average intakes of energy and most nutrients in the general diet group were significantly higher than those of the other two groups. Significant differences in diet quality and diet diversity were observed according to the meal type groups. The NARs of some minerals (calcium, iron, and zinc) and vitamins (vitamin B6 and folic acid) were less than 0.5 in all study groups. The NARs of protein, iron and MAR of the general diet group were significantly higher than those of the liquid diet group. The DDS scores of meats, fruits and diary food group were very low in all meal type groups, meaning that the diet qualities of the study subjects were not appropriate in all meal type groups. CONCLUSIONS: The food intakes of the study groups showed some limitations by a direct comparison with KDRIs because of the very low physical activities of the study subjects. The diet quality and diet diversity indices suggest the need for improvements in the nutritional quality in all types of diet. Overall, new intervention strategies targeting facility residents with dementia in Korea are needed as soon as possible.

PURPOSE: To evaluate clinical characteristics of pediatric nontraumaitc chylothorax and to suggest appropriate therapeutic managements. METHODS: We retrospectively reviewed medical records of 22 patients with nontraumatic chylothorax from January 2005 to December 2018 in the Children's Hospital of Seoul National University. We analyze their etiology, treatment, complications and outcome. RESULTS: Of the 22 patients, 16 were diagnosed before 1 year old and 6 after 1 year old. The causes of chylothorax under 1-year-old children were related to congenital factors (n=9), unknown causes (n=5), and high central venous pressure (n=2). The causes of chylothorax over 1-year-old children were related to congenital factors (n=3), unknown causes (n=1), high venous pressure (n=1), and lymphoma (n=1). All patients had dietary modification. Eight of them were cured by dietary modification, but there was no improvement in over 1-year-old children. Medication was added to patients refractory to dietary modification. Four patients with medication were improved and 5 were improved by surgical management. Nutritional, immunological and other complications occurred in many patients. Five death cases were reported. Four patients were under 1 year old and 1 was over 1 year old. The causes of nontraumatic chylothorax in dead patients were high central venous pressure (n=3), congenital (n=1), and unknown (n=1). CONCLUSION: Nontraumatic chylothorax more frequently occurs in under 1-year-old children. The most common cause is congenital factors. Stepwise management is effective in many patients, but specific treatment is needed in some cases. The prognosis is related to the onset of age and underlying diseases.

OBJECTIVE: To examine the clinical factors and brain lesion locations related to the patterns of dysphagia in stroke patients in a rehabilitation hospital. METHODS: The medical records of 116 stroke patients who underwent a videofluoroscopic swallowing study (VFSS) between January 2010 and January 2015 in a rehabilitation hospital were reviewed retrospectively. The swallowing-related parameters were assessed using a VFSS. The brain lesion locations were classified as the cortex, basal ganglia, thalamus, midbrain, pons, medulla, cerebellum, and others (subarachnoid or intraventricular hemorrhage). The ambulation ability was assessed using functional ambulation categories (FACs). The independence in the activities of daily living and the degree of cognitive impairment were assessed using the Korean versions of the modified Barthel index (K-MBI) and Mini-Mental State Examination (K-MMSE), respectively. After adjusting for the potential confounding factors in multivariate analysis, the odds ratios and confidence intervals of the stroke brain lesions were calculated and the clinical factors for predicting the VFSS findings were determined. RESULTS: Among the 116 patients, 35 (27%) had an impaired oral stage and 58 (50%) had aspiration. The impaired oral stage was associated significantly with the onset time, basal ganglia stroke, dietary and fluid intake methods at the time of the VFSS, symptoms of dysphagia, FACs, K-MBI, and K-MMSE. Aspiration was correlated with a pontine stroke, methods of dietary and fluid intakes at the time of the VFSS, symptoms of dysphagia, FACs, and K-MBI. Multivariate analysis showed that the pontine stroke and methods of dietary and fluid intake at the time of VFSS predicted aspiration after adjusting for the potential confounding factors. In subgroup analysis of the diet type, the liquid and semisolid aspirations were correlated with the dietary and fluid intake methods and pontine stroke, respectively. CONCLUSION: Patients with a pons lesion stroke, who are on a modified diet (fluid thickening and tube feeding), have higher risks of aspiration. This provides evidence for precise clinical reasoning in this specific patient group.

BACKGROUND: Elimination diets are used to treat eosinophilic esophagitis (EoE), with success (remission) defined at endoscopy and oesophageal biopsy as fewer than 15 eosinophils per high power field (HPF). Response is assessed after 6 weeks of treatment by convention, but we have observed that this period of time may be insufficient. OBJECTIVE: To characterise a subset of patients with EoE who require prolonged (>6 weeks) of dietary therapy to achieve histologic remission. METHODS: A retrospective search of electronic medical records of 2 cohorts with EoE attending the Department of Gastroenterology, University of Chapel Hill North Carolina, and Eastern Health, Melbourne Australia. Patients who underwent elimination diet, had esophageal biopsy after 6 or more weeks of dietary restriction that demonstrated ongoing esophageal inflammation (>15 eosinophils per HPF), and who then continued dietary therapy followed by repeat endoscopy demonstrating remission (<15 eosinophils per HPF) were included. RESULTS: Seven patients met inclusion criteria, average esophageal eosinophil counts prior to diet was 38.5 (range, 15–65). Following the initial period of diet (mean of 6 weeks and 4 days) eosinophil count decreased (average, 21.5/HPF; range 15–40/HPF). After extended dietary elimination (mean, 13 weeks; range, 7–22 weeks), histological resolution was achieved (average peak eosinophil count of 5.2; range, 0–14) in all cases. Endoscopic appearance and symptoms both improved following the initial period of dietary elimination, thereby preceding the histological resolution, and were sustained. CONCLUSION: A subset of patients has full histologic response to prolonged elimination diet, that lags initial symptomatic and endoscopic improvement.

PURPOSE: This study was implemented to develop and validate the semi-quantitative food frequency questionnaire (SQ-FFQ) to assess energy, carbohydrates, fat, protein, minerals, and vitamins as well as fatty acids and alcohol in Korean adults. METHODS: The SQ-FFQ consisted of 88 food items, and 12 food groups were selected based on information of frequently consumed foods from the Korean Health and Nutrition Examination survey. Each portion size was categorized as one of three amounts: small (0.5 times), medium (1 time), and large (1.5 times). A total of 111 subjects finished 3-day diet records and the SQ-FFQ. The relative validity of SQ-FFQ was assessed by comparison with the 3-day diet records. RESULTS: The mean nutrient intakes obtained from the SQ-FFQ were estimated to be greater than those of the two 3-day dietary records. Spearman's correlation coefficient between the two methods was the highest for energy (r = 0.583; p < 0.001) and lowest for saturated fatty acid (r = 0.121). Correlation coefficients were energy (r = 0.583; p < 0.001), carbohydrates (r = 0.500; p < 0.001), protein (r = 0.466; p < 0.001), fat (r = 0.411; p < 0.001), dietary fiber (r = 0.467; p < 0.001), alcohol (r = 0.527; p < 0.001), calcium (r = 0.409; p < 0.001), phosphorus (r = 0.499; p < 0.001), potassium (r = 0.418; p < 0.001), magnesium (r = 0.427; p < 0.001), and zinc (r = 0.464; p < 0.001), respectively, for all subjects. CONCLUSION: The developed SQ-FFQ in this study seems to be useful for estimating nutritional status, particularly energy, carbohydrates, protein, fat, dietary fiber, alcohol, calcium, phosphorus, potassium, magnesium, and zinc of Korean adults.

BACKGROUND: The eating habits of Jeju Island natives are quite different from those of the mainland people because of geographic isolation. Diet is a main factor affecting gallstone disease. We investigated the prevalence of gallstone disease in both Jeju Island natives and migrants and studied the risk factors affecting gallstone disease in the Jeju Island people. METHODS: A total of 20,763 subjects who underwent medical checkups at the Health Promotion Center of Jeju National University Hospital in Korea from January 2003 to December 2015 were enrolled in the study. Ultrasonography was used to determine the presence of gallbladder stones. Body mass index and biochemical parameters, including liver function test results, lipid profiles, and fasting blood glucose levels, were verified, and data on age, birthplace, and sex were collected from medical records. Univariate and multivariate analyses were performed to identify risk factors affecting gallstone disease. RESULTS: The prevalence of gallstone disease in the Jeju Island people was 4.0%: Jeju Island natives, 3.8% and migrants, 4.4% (P=0.047). After multivariate logistic regression analysis, the independent risk factors were older age, Jeju migrants, higher fasting blood glucose and alanine aminotransferase levels, and lower high-density lipoprotein cholesterol levels. CONCLUSION: The prevalence of gallstone disease was significantly lower in natives than in migrants from Jeju Island. Older age, Jeju migrants, higher fasting blood glucose and alanine aminotransferase levels, and lower high-density lipoprotein cholesterol levels contributed to gallstone disease prevalence in the Jeju Island people.

PURPOSE: Laparoscopic adhesiolysis is increasingly used to treat patients with small bowel obstruction (SBO), however, its safety of laparoscopic surgery(LS) with bowel resection in SBO is unclear. The purpose of the present study was to compare the perioperative outcomes of LS with those of open surgery (OS) for SBO and to evaluate the risk factors of 30-day postoperative morbidity and recurrence. METHODS: We retrospectively reviewed medical records of patients who had been diagnosed with SBO and underwent surgery at four Hallym-University-affiliated hospitals between January 2013 and December 2016. The rates of 30-day postoperative complications and recurrence were compared between groups using univariate and multivariate analysis. Propensity score matching was performed to compare the outcome. RESULTS: A total of 117 patients with SBO were included in the present study, of which 86 underwent OS and 31 underwent LS. Time to water intake, time to soft diet, and postoperative hospital stay were significantly shorter in the LS group (p=0.002, 0.003, and 0.027, respectively). The complication (p=0.249) and recurrence rate (p=0.679) were similar between the two group. Propensity score matching analysis demonstrated that laparoscopic surgery showed quicker recovery and similar complication and recurrence rate. In multivariate analysis, LS was not associated with either complications (p=0.806) or recurrence (p=0.956). CONCLUSION: LS is associated with several perioperative advantages for the treatment of SBO without affecting the risk of 30-day postoperative complications or recurrence. Therefore LS can be a safe and feasible option for treating SBO.

OBJECTIVEUndernutrition is highly prevalent among older people. The aim of this study was to estimate the prevalence of undernutrition in elderly Chinese residents and explore the relationship between undernutrition and dietary factors.

METHODSData were collected from 2,552 elderly people aged 75 years and over from the Chinese Nutrition and Health Surveillance during 2010-2012 using questionnaires, anthropometric measurement, and individual consecutive 3-day 24-hour dietary records.

RESULTSThe present study showed that 10.5% of participants had undernutrition. The prevalence was higher among the population living in rural areas, those living in the South region, those who smoked, and those with low income levels. Most participants failed to meet the Chinese Dietary Reference Intakes for energy (66.1%) and protein (72.1%). When comparing quartiles of food intake, high rice consumption [odds ratio (OR) = 2.44, 95% confidence interval (CI): 1.35-4.40)], animal oil intake (OR = 1.60, 95% CI: 1.18-2.17), and high fat intake from animal sources (OR = 1.56, 95% CI: 1.06-2.31) were positively associated with underweight whereas high wheat consumption (OR = 0.44, 95% CI: 0.26-0.74), a proper proportion (24%-32%) of energy intake from fat (OR = 0.54, 95% CI: 0.35-0.83), and high fat intake from plant sources (OR = 0.67, 95% CI: 0.46-0.99) were inversely related.

CONCLUSIONThe prevalence of undernutrition was high among elderly Chinese people, especially in rural areas. Dietary factors, such as high consumption of rice, were associated with undernutrition.

Intensive care units (ICUs) provides intensive treatment medicine to avoid complications such as malnutrition, infection and even death. As very little is currently known about the nutritional practices in Iranian ICUs, this study attempted to assess the various aspects of current nutrition support practices in Iranian ICUs. We conducted a cross-sectional study on 150 critically ill patients at 18 ICUs in 12 hospitals located in 2 provinces of Iran from February 2015 to March 2016. Data were collected through interview with supervisors of ICUs, medical record reviews and direct observation of patients during feeding. Our study showed that hospital-prepared enteral tube feeding formulas are the main formulas used in Iranian hospitals. None of the dietitians worked exclusively an ICU and only 30% of patients received diet counselling. Regular monitoring of nutritional status, daily energy and protein intake were not recorded in any of the participating ICUs. Patients were not monitored for anthropometric measurements such as mid-arm circumference (MAC) and electrolyte status. The nasogastric tube was not switched to percutaneous endoscopic gastrostomy or jejunostomy (PEG/PEGJ) in approximately 85% of patients receiving long-term enteral nutrition (EN) support. Our findings demonstrated that the quality of nutritional care was inappropriate in Iranian ICUs and improvement of nutritional care services within Iranian ICUs is necessary.
