Perspectives of East Asian patients and physicians on complementary and alternative medicine use for inflammatory bowel disease: results of a cross-sectional, multinational study

Background/Aims@#Complementary and alternative medicine (CAM) is prevalent in East Asia. However, information on CAM in East Asian patients with inflammatory bowel disease (IBD) is scarce. We aimed to profile the prevalence and pattern of CAM use among East Asian IBD patients and to identify factors associated with CAM use. We also compared physicians’ perspectives on CAM. @*Methods@#Patients with IBD from China, Japan, and South Korea were invited to complete questionnaires on CAM use. Patient demographic and clinical data were collected. Logistic regression analysis was applied for predictors of CAM use. Physicians from each country were asked about their opinion on CAM services or products. @*Results@#Overall, 905 patients with IBD participated in this study (China 232, Japan 255, and South Korea 418). Approximately 8.6% of patients with IBD used CAM services for their disease, while 29.7% of patients sought at least 1 kind of CAM product. Current active disease and Chinese or South Korean nationality over Japanese were independent predictors of CAM use. Chinese doctors were more likely to consider CAM helpful for patients with IBD than were Japanese and South Korean doctors. @*Conclusions@#In 8.6% and 29.7% of East Asian patients with IBD used CAM services and products, respectively, which does not differ from the prevalence in their Western counterparts. There is a significant gap regarding CAM usage among different Asian countries, not only from the patients’ perspective but also from the physicians’ point of view.

Estimation of vitamin K intake in Koreans and determination of the primary vitamin K-containing food sources based on the fifth Korean National Health and Nutrition Examination Survey (2010-2011)

There is little information on dietary vitamin K intake and nutritional status of daily requirements of vitamin K in Korea. The objective of this study was to investigate the vitamin K intake and major food sources of Vitamin K in Koreans. The survey data from the 2010-2011 Korean National Health and Nutrition Examination Survey of 7,792 subjects (aged 19-64 years) were examined. Total vitamin K intake was calculated from 24-hour dietary recall using a vitamin K food database, Computer Aided Nutritional analysis Program and the United States Department of Agriculture database. The geometric mean of vitamin K was estimated as 322.40 +/- 6.33 ug/day for men and 271.20 +/- 4.92 ug/day for women. Daily vitamin K intake increased significantly with age (p for trend < 0.001). The main food source of vitamin K was vegetables (72.84%), including cabbage kimchi (19.26%), spinach (17.38%), sesame leaves (7.11%), radish leaves (6.65%), spring onions (6.28%), and laver (4.82%), followed by seaweed, seasonings, and fat and oils. We observed that the vitamin K intake of Koreans was relatively higher than that reported by other studies in Western countries and differed depending on age.

Alterations of Colonic Contractility in Long-term Diabetic Rat Model

BACKGROUND/AIMS: Dysfunction of the gastrointestinal tract occurs in about 76% of patients who are diabetic for more than 10 years. Although diabetes-related dysfunctions of the stomach such as gastroparesis have been extensively studied over the recent years, studies about the mechanism underlying colonic symptoms in long-term diabetes models are rare. Therefore, the goal of our study was to clarify the nature of colonic dysfunction in a long-term diabetic rat model. METHODS: The characteristics of colonic smooth muscle were investigated in Otsuka Long-Evans Tokushima Fatty (OLETF) rats, an animal model of type 2 diabetes. These results were compared to those obtained from Long-Evans Tokushima Otsuka (LETO) control rats. RESULTS: Spontaneous contractility of the proximal colon was significantly decreased in the diabetic rats compared to the controls, while the spontaneous contractility of the distal colon was not. The number of interstitial cells of Cajal networks in the proximal colon was greatly decreased in diabetic rats compared to the controls. Contractility of the proximal colon in response to carbachol, an acetylcholine receptor agonist, was significantly weaker in the diabetic rats. In addition, the degree of relaxation in response to nitric oxide in the proximal colon of diabetic rats also appeared to be attenuated. CONCLUSIONS: The results from our study suggest that the decrease of interstitial cells of Cajal network, cholinergic receptors, and neuronal nitric oxide synthase in the proximal colon plays important roles in diabetes-related dysfunction of colon.

Clinical Characteristics of Gastroesophageal Reflux Disease with Esophageal Injury in Korean: Focusing on Risk Factors / 대한소화기학회지

BACKGROUND/AIMS: Recent studies suggest that the prevalence of gastroesophageal reflux disease (GERD) is increasing in Korea. However, studies on risk factors for GERD have yielded inconsistent results. The aims of this study were to compare clinical features between symptomatic syndromes without esophageal injury (=non-erosive disease [NED]) and syndromes with esophageal injury (=erosive disease [ED]), and to determine risk factors associated ED. METHODS: A total of 450 subjects who visited gastroenterology clinics of six training hospitals in Daegu from March 2008 to April 2010 were consecutively enrolled. The subjects were asked to complete a questionnaire which inquired about gastroesophageal reflux symptoms. The questionnaire also included questions about smoking, alcohol drinking, consumption of coffee, use of drugs, exercise, and other medical history. The subjects were subdivided into NED and ED groups. RESULTS: The proportion of subjects in each NED and ED group was 172 (38.2%) and 278 (61.8%). Male gender, smoking, alcohol drinking, consumption of coffee, large waist circumference, infrequent medication of antacids, aspirin and NSAIDs, infrequent and mild GERD symptoms were all significantly associated with ED on univariate analysis. Age, hiatal hernia, diabetes mellitus, body mass index, change in weight during 1 year, and number of typical GERD symptoms were not independent risk factors for ED. However, the association between ED and alcohol drinking, infrequent medication of antacids, mild typical GERD symptoms remained as strong risk factors after adjustments on multivariate logistic analysis. CONCLUSIONS: Independent risk factors associated with ED were alcohol drinking, infrequent medication of antacids and mild typical GERD symptoms.

The Changes of BIS and Hemodynamic Variables during Pediatric Open Heart Surgery with Sevoflurane or Midazolam / 대한마취과학회지

BACKGROUND: The bispectral index (BIS) has been shown to be useful for monitoring the degree of hypnosis in anesthetized adults. Although several studies have been performed to evaluate BIS in pediatric patients, it is unclear whether a BIS monitor can be applied in infants. This study was designed to evaluate changes of BIS, mean arterial pressure and heart rate during anesthesia with sevoflurane or midazolam in pediatric open heart surgery patients. METHODS: Eighteen patients under 3 years of age scheduled for an elective cardiac surgery were studied. Group S (n = 9) received sevoflurane-fentanyl, group M (n = 9) received midazolam-fentanyl. BIS, mean arterial pressure, heart rate, temperature, and end-tidal sevoflurane concentrations were obtained during anesthesia and surgery including cardiopulmonary bypass. The amount of fentanyl injected on an as needed base, total mechanical ventilation duration and intensive care unit stay were compared. RESULTS: A significant overall association between BIS and temperature was observed (Group S; R2 = 0.309, Group M; R2 = 0.225). There were no correlation between BIS and mean arterial pressure, heart rate, end-tidal sevoflurane concentration, and were no difference in the BIS scores of the groups. The mean arterial pressure of the M group from incision to CPB and post CPB 30 minutes were greater than those of the S group. The dose of fantanyl injected as needed during operation was greater in the M group than in the S group. No significant differences in the perisod of ventilation care and ICU stay. CONCLUSIONS: BIS decreased in both groups of patients as temperature decreased. Midazolam and fentanyl anesthesia in congenital heart disease may cause insufficient anesthesia regardless of BIS scores.

A Case of Iatrogenic Wernicke's Encephalopathy Following Chemotherapy and Total Parenteral Nutrition / 대한혈액학회지

Wernicke's encephalopathy is a neuropsychiatric condition generally caused by acute thiamine deficiency. Although it is common in the severe alcoholics, several other causes also have been identified, such as total parenteral nutrition (TPN) use, persistent vomiting, hyperemesis gravidarum, anorexia nervosa and malnutrition. The classic triad of Wernicke's encephalopathy are ataxia, altered mentation and ophthalmoplegia. A 19-year-old boy had been treated with high dose Ara-C and mitoxantrone for acute myelogenous leukemia and intravenous hyperalimentation due to persistent vomiting. He suddenly complained of diplopia, gait disturbance and generalized weakness at 36th day after chemotherapy. Physical examinations showed disorientated mentality, oculomotor palsy and horizental nystagmus. The diagnosis of Wernicke's encephalopathy was made with classical brain MRI and decreased thiamine level. The patient was successfully treated with vitamin B1. We presented a case of acute Wernicke's encephalopathy developed after high dose Ara-C chemotherapy followed by intravenous hyperalimentation in a patient with acute myelogenous leukemia.
