Diabetes should maintain normal blood glucose through the self-management to show the progression of complications, and prevention of diabetes complications. So far, self-monitoring of blood glucose (SMBG) has been the most basic elements of self-management of diabetes. Through SMBG, it is possible for diabetes to monitor the variation of the amount and type they eat, exercise and stress. However, the patient is not easy to apply and interpret the result of the self-measured blood glucose control. It requires appropriate feedback from professional but feedback is not completed because of the constraints of time and space. This inhibitory factor was now enable interactive communication between the practitioner and the patient regardless of time and place with the development of information and communication. The mobile app makes it easier to analyze and interpret SMBG data patterns. Now mobile diabetes apps based on smartphone apps are evolving as an essential tool, not as an aid to help improve the selfmanagement of people with diabetes. Diabetes educators should be interested in developing content for mobile diabetes apps and provide professional monitoring and feedback.

Purpose: For this study the effect of skin disinfection according to the disinfection frequency in peripheral intravenous therapy was examined. Methods: One hundred and twenty skin disinfections, three sections on the right forearm and three sections on the left forearm, were performed on each of 20 seniors in the school of nursing, and 240 microbial cultures were performed before and after the skin disinfection at each site. Single-use sterile packaged 83% alcohol cotton was used to disinfect. The skin was disinfected once, twice, or three times for 5 seconds per session and then allowed to dry for one minute. The data were analyzed using the Kruskal-Wallis test and the Generalized Estimation Equation (GEE). Results: There was no significant difference in the number of microbial colonies by the number of disinfections (p=.599) as well as the number of microbial colonies among those disinfected the same number of times (p=.440). However, the number of microbial colonies after disinfection was significantly lower than that before disinfection (p<.001). The interaction effect, which was the difference in the decrease of microbial colonies by the number of disinfections, was not significant (p=.101). Conclusion Prior to peripheral intravenous injection, disinfecting the skin once for five seconds with an 83% alcohol swab was as effective as disinfecting it twice for 10 seconds or three times for 15 seconds. Therefore, disinfecting the skin thoroughly for 5 seconds or more with an 83% alcohol cotton swab is sufficient for peripheral vein injections in the clinical field.

OBJECTIVES: Maintaining the constant exposure to hydrophobic organic compouds in acute toxicity tests is one of the most difficult issues in the evaluation of their toxicity and corresponding risks. Passive dosing is an emerging tool to keep constant aqueous concentration because of the overwhelming mass loaded in the dosing phase. The primary objectives of this study were to develop the constant exposure condition for an acute mortality test and to compare the performance of the passive dosing method with the conventional spiking with co-solvent. METHODS: A custom cut polydimethylsiloxane (PDMS) tubing loaded with benzyl butyl phthalate (BBP) was placed in each well of a 24-well plate containing assay medium. The rate of the release of BBP from PDMS was evaluated by measuring the change in the concentration of BBP in the assay medium. The efficiency of maintaining constant exposure condition was also evaluated using a simple two-compartment mass transport model employing a film-diffusion theory. An acute mortality test using 10 C. elegans in each well was conducted for the evaluation of the validity of passive dosing and the comparative evaluation of the passive dosing method and the conventional spiking method. RESULTS: Free concentration in the assay medium reached 95% steady state value within 2.2 hours without test organisms, indicating that this passive dosing method is useful for an acute toxicity test in 24 hours. The measured concentration after the mortality test agreed well with the estimated values from partitioning between PDMS and the assay medium. However, the difference between the nominal and the free concentration became larger as the spiked concentration approached water solubility, indicating the instability of the conventional spiking with a co-solvent. CONCLUSIONS: The results in this study support that passive dosing provides a stable exposure condition for an acute toxicity test. Thus, it is likely that more reliable toxicity assessment can be made for hydrophobic chemicals using passive dosing.

Percutaneous device closure for secundum atrial septal defects (ASDs) has been performed commonly and safely with high success rates. However, it is still challenging to close ASDs that are surrounded with deficient or hypermobile rims and could be compromised with an unexpected migration of device. We report a case of percutaneous Amplazter Septal Occluder (ASO; St. Jude Medical Inc., St. Paul, Minnesota, USA) device closure for an ASD with a thin and floppy interatrial septum, which immediately migrated into the right atrium and was not pulled back into the delivery sheath. To our knowledge, this is the first report on a successful percutaneous retrieval and redeployment of the device in such a situation, preventing any vascular injury or unplanned emergency open heart surgery.

PURPOSE: Homeless patients usually live outside and are therefore frequently exposed to injury and tetanus infection. Thus, after visits to an emergency department (ED) due to injury, homeless patients need to be vaccinated for the prevention of tetanus infection with tetanus immunoglobulin regardless of tetanus antibody titer or previous vaccination history. Because the exact history of previous tetanus vaccination in homeless patients is unclear, the tetanus antibody titer between homeless patients and general patients was assessed. METHODS: Subjects who visited the ED after injury from October 2008 to February 2010 were enrolled. All participants answered questions on age, gender, previous vaccination or prophylaxis history, and military service. The Tetanus Immunoglobulin G ELISA (Enzyme-linked immunosorbent assay) method was used for the analysis of serum samples. Propensity score-matched analysis was used to control for age, gender, previous vaccination or prophylaxis history, and military service. RESULTS: A total of 1325 samples were analyzed. There was 83 samples from homeless patients and 1242 samples from general patients. After matched analysis using the propensity score, 56 subjects were matched. The geometric mean titer of tetanus antibody was 0.204+/-0.392 IU/mL in homeless patients and 0.105+/-0.143 IU/mL in general patients (p=0.078). The proportion of patients with a safe tetanus antibody titer was 66.1 percent of homeless patients and 23.2 percent of general patients (p<0.001). CONCLUSION: Homeless patients had a higher mean titer and a statistically higher proportion had a safe titer compared to general patients.

BACKGROUND: The purpose of this study is to investigate family caregivers' opinions about out-of-pocket payment for long-term care (LTC) facilities, and find the differences in the opinions for family caregivers of all different levels of income. METHODS: We used the data of the study on out-of-pocket payment in national long-term care insurance, including 1,552 family caregivers with the elderly in long-term care facilities. RESULTS: The average out-of-pocket payment per month was 511,635 Korean won and distributed from 230,750 to 1,365,570 Korean won. The amount of out-of-pocket payment might be affected by not co-payment but the cost of non-covered service. There were differences in them for family caregivers of all different levels of income. Opinions were surveyed about 5 issues. By levels of income, there were differences in their opinions about 3 issues, the financial burden on LTC, the necessity of reducing out-of-pocket payments, and to be willing to pay more for a high quality service. But there were not different opinions about the interruption of LTC service and staying with LTC facilities. CONCLUSION: These findings suggest that the range of out-of-pocket payment for LTC facility is wide and it can be a burden to lower income group. It should be to prepare the policies to ease the financial burden and support the appropriate LTC use.

This study was undertaken to examine effects of dietary intake of garcinia cambogia extract, soy peptide and L-carnitine mixture on body weight gain and obesity-related bio-markers in rats fed high-fat diet for 9 weeks with or without regular treadmill exercise. Forty 5-week-old male Sprague-Dawley rats were randomly divided into four groups; sedentary control group (SC), exercised control group (EC), sedentary formula-fed group (SF), and exercised formula-fed group (EF). The SC and EC rats were fed high-fat control diet (fat comprises 40% of total caloris), and SF and EF rats were fed high-fat formula (composed of garcinia cambogia, soy peptide and L-carnitine) supplemented diet. Statistical analyses by two-way ANOVA indicated that the regular treadmill exercise significantly lowered cumulative body weight gain, total visceral fat mass, and epididymal, perirenal and retroperitoneal fat pad weights, and serum concentrations of total cholesterol and LDL + VLDL cholesterol, insulin, c-peptide and leptin. Feeding the formula also resulted in significant reductions in cumulative body weight gain and visceral fat pad weights, along with other related parameters including serum total and LDL + VLDL cholesterol levels, and hepatic enzyme activities involved in fatty acid synthesis. Statistical analyses by one-way ANOVA revealed that the formula consumption significantly improved body weight gain (18% reduction), total visceral fat weight (20% reductions), and serum total (43% reduction) and LDL + VLDL cholesterol (54% reduction) levels, as well as serum levels of insulin (49% reduction), and c-peptide (41% reduction) in sedentary rats, but failed to exhibit significant reductions in these indices in animals under treadmill exercise program. Taken together, these results suggest that the treadmill exercise per se exhibited significant improvements in body fat reduction and other related bio-markers, and so the formula consumption did not achieve a further significant reductions in these bio-markers in exercised rats. Nevertheless, animals fed the formula with regular exercise showed the most efficient weight reduction compared to other groups either fed formula without exercise or received regular exercise without dietary supplementation.

Background/Aims: Studies have reported an association between fecal occult blood and increased all-cause, non-colorectal cancer (CRC) as well as CRC mortality. This study aimed to determine whether positive fecal immunochemistry test (FIT) results are associated with death from various causes in the South Korean population. Methods: Using the Korean National Cancer Screening Program database, we collected data on patients who underwent FIT between 2009 and 2011. Results: Of the 5,932,544 participants, 380,789 (6.4%) had positive FIT results. FIT-positive participants had a higher mortality rate than FIT-negative participants from CRC (1.33 and 0.21 per 1,000 person-years, p < 0.001, respectively) and non-CRC causes (10.40 and 7.50 per 1,000 person-years, p < 0.001, respectively). Despite adjusting for age, sex, smoking status, alcohol consumption habits, body mass index, comorbidity, and aspirin use, FIT positivity was associated with an increased risk of dying from all non-CRC causes (adjusted hazard ratio [aHR], 1.17; 95% confidence interval [CI], 1.15 to 1.18) and CRC (aHR, 5.61; 95% CI, 5.40 to 5.84). Additionally, FIT positivity was significantly associated with increased mortality from circulatory disease (aHR, 1.14; 95% CI, 1.11 to 1.17), respiratory disease (aHR, 1.14; 95% CI, 1.09 to 1.19), digestive disease (aHR, 1.57; 95% CI, 1.48 to 1.66), neuropsychological disease (aHR, 1.08; 95% CI, 1.01 to 1.16), blood and endocrine diseases (aHR, 1.10; 95% CI, 1.04 to 1.17), and external factors (aHR, 1.16; 95% CI, 1.11 to 1.20). Conclusions Positive FIT results are associated with an increased risk of mortality from CRC and various other chronic diseases, suggesting that it could be a predictor of mortality independent of its association with CRC.

Background/Aims: Annual fecal immunochemical tests (FITs) are often repeated within the recommended colonoscopy surveillance intervals. However, it remains unclear whether interval FITs are useful. To answer this question, we assessed the risk of colorectal cancer (CRC) according to the interval from the last colonoscopy to an FIT. Methods: Using the Korean National Cancer Screening Program database, we collected data on patients who underwent FITs in 2011. Patients with positive FIT results were classified into three groups according to their previous colonoscopy interval: 0.5 to 5 years (group 1), 5 to 10 years (group 2), and ≥ 10 years or no colonoscopy (group 3). CRC incidence was defined as CRC diagnosed within 1 year after an FIT. Results: Among 177,660 patients with positive FIT results, the incidence of CRC in groups 1, 2, and 3 was 0.72% (n = 214/29,575), 1.28% (n = 116/9,083), and 3.88% (n = 5,387/139,002), respectively. The age- and sex-adjusted risk for CRC was higher in groups 2 (odds ratio [OR], 1.79; 95% confidence interval [CI], 1.43 to 2.25) and 3 (OR, 5.56; 95% CI, 4.85 to 6.38) than in group 1. Among patients who did and did not undergo a polypectomy during the previous colonoscopy, those in group 2 had a higher rate of CRC than those in group 1 (without polypectomy: 1.15% vs. 0.63%; OR, 1.79; 95% CI, 1.37 to 2.34) (with polypectomy: 2.37% vs. 0.93 %; OR, 2.30; 95% CI, 1.44 to 3.69). Conclusion In patients with positive FIT results who had undergone a colonoscopy within the past 5 years, the risk of CRC is very low, regardless of whether a polypectomy was performed, suggesting that interval FITs are not useful.
