Selected AbstractsComparisons between a mixing ability test and masticatory performance tests using a brittle or an elastic test foodJOURNAL OF ORAL REHABILITATION, Issue 3 2009T. SUGIURA Summary, A variety of chewing tests and test items have been utilized to evaluate masticatory function. The purpose of this study was to compare a mixing ability test with masticatory performance tests using peanuts or gummy jelly as test foods. Thirty-two completely dentate subjects (Dentate group, mean age: 25·1 years) and 40 removable partial denture wearers (RPD group, mean age: 65·5 years) participated in this study. The subjects were asked to chew a two-coloured paraffin wax cube as a test item for 10 strokes. Mixing Ability Index (MAI) was determined from the colour mixture and shape of the chewed cube. Subjects were asked to chew 3 g portions of peanuts and a piece of gummy jelly for 20 strokes, respectively. Median particle size of chewed peanuts was determined using a multiple-sieving method. Concentration of dissolved glucose from the surface of the chewed gummy jelly was measured using a blood glucose meter. Pearson's correlation coefficient was used to test the relationships between the MAI, median particle size and the concentration of dissolved glucose. Mixing Ability Index was significantly related to median particle size (Dentate group: r = ,0·56, P < 0·001, RPD group: r = ,0·70, P < 0·001), but not significantly related to glucose concentration (Dentate group: r = 0·12, RPD group: r = 0·21, P > 0·05). It seems that ability of mixing the bolus is more strongly related to the ability of comminuting brittle food than elastic food.

King ABSTRACT The cutaneous delivery pathway through the lymphatics of a novel transdermal lipid-based delivery system (biphasic vesicles), which was previously shown to deliver sustained physiological levels of basal insulin in a pain-free manner across the skin, was evaluated in a diabetic rat model. Transdermal patches (one per rat) containing insulin in biphasic vesicles (1,10 mg recombinant human insulin dose) were applied to the shaved abdominal skin of streptozotocin-induced diabetic rats for 73 h. Blood glucose was monitored approximately every 2,10 h using a Lifescan glucose meter. Inguinal lymph node insulin levels were analysed by ELISA. Insulin in the lymph nodes increased in a dose- and time-dependent manner. Maximal transdermal insulin concentrations in the lymph nodes were observed with both 140 IU (5 mg: 43.0 + 18.0 ,IU mg,1 (mean + s.e.m., n = 4)) and 280 IU (10 mg: 48.0 + 19.6 ,IU mg,1 (mean + s.e.m., n = 4)) doses of recombinant insulin at t = 73 h. The level of insulin in the lymph nodes after subcutaneous injection of 1 mg insulin at the peak blood glucose response was 35.8 ,IU mg,1 (n = 2), before falling to 0.35 ,IU mg,1 by t = 48 h (n = 2). The lymphatics is involved in the transdermal insulin delivery by biphasic vesicles. This is the first report on the lymphatic transport of a protein after non-invasive topical application on the skin. [source] Evaluation of a Novel Real-Time Continuous Glucose-Monitoring System for Use in CatsJOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 1 2010S. Moretti Background: The Guardian REAL-Time is a continuous glucose-monitoring system (CGMS) recently developed to provide instantaneous interstitial glucose concentrations; the system does not require a monitor being fixed to the animal. Hypothesis: The CGMS provides accurate and reproducible real-time readings of glucose concentration in cats. Animals: Thirty-two diabetic cats, 2 cats with suspected insulinoma, and 5 healthy cats. Methods: Prospective, observational study. CGMS accuracy was compared with a reference glucose meter at normal, high, and low blood glucose concentrations using error grid analysis. Reading variability of 2 simultaneously used CGMS was determined in diabetic cats by calculating correlation and percentage of concordance of paired data at different glycemic ranges. The time interval between increasing glycemia and a rise in interstitial fluid glucose measured by the CGMS was assessed in healthy cats receiving glucose IV; the time point of maximal increase in interstitial glucose concentrations was calculated. Results: The CGMS was 100, 96.1, and 91.0% accurate at normal, high, and low blood glucose concentrations. Measurements deviated from reference by ,12.7 ± 70.5 mg/dL at normal, ,12.1 ± 141.5 mg/dL at high, and ,1.9 ± 40.9 mg/dL at low glucose concentrations. Overall, paired CGMS readings correlated significantly (r= 0.95, P < .0001) and concordance was 95.7%. The median delay after IV administration of glucose to an increase in interstitial glucose was 11.4 minutes (range: 8.8,19.7 minutes). Conclusions and Clinical Importance: Although some readings substantially deviated from reference values, the CGMS yields reproducible results, is clinically accurate in cats with hyperglycemia and euglycemia, and is slightly less accurate if blood glucose concentrations are low. Rapidly increasing interstitial glucose after a glycemic rise suggests that the CGMS is suitable for real-time measurement under clinical conditions. [source] Extreme altitude mountaineering and Type 1 diabetes; the Diabetes Federation of Ireland Kilimanjaro ExpeditionDIABETIC MEDICINE, Issue 9 2001K. Moore Abstract Aims To examine the effects of extreme altitude mountaineering on glycaemic control in Type 1 diabetes, and to establish whether diabetes predisposes to acute mountain sickness (AMS). Methods Fifteen people with Type 1 diabetes and 22 nondiabetic controls were studied during the Diabetes Federation of Ireland Expedition to Kilimanjaro. Daily insulin requirements, blood glucose estimations and hypoglycaemic attacks were recorded in diaries by the people with diabetes. The performance of blood glucose meters at altitude was assessed using standard glucose solutions. Symptoms of acute mountain sickness were recorded daily by people with diabetes and by the nondiabetic controls using the Lake Louise Scoring Charts. The expedition medical team recorded the incidence of complications of altitude and of diabetes. The final height attained for each individual was recorded by the expedition medical team and verified by the expedition guides. Results The final altitude ascended was lower in the diabetic than the nondiabetic group (5187 ± 514 vs. 5654 ± 307 m, P= 0.001). The mean daily insulin dose was reduced from 67.1 ± 28.3,32.9 ± 11.8 units (P < 0.001), but only 50% of recorded blood glucose readings were within the target range of 6,14 mmol/L. There were few hypoglycaemic attacks after the first two days of climbing. Both blood glucose meters tested showed readings as low as 60% of standard glucose concentrations at high altitude and low temperatures. The Lake Louise questionnaires showed that symptoms of AMS occurred equally in the diabetic and nondiabetic groups. There were two episodes of mild diabetic ketoacidosis; two of the diabetic group and three of the nondiabetic group developed retinal haemorrhages. Conclusions People with Type 1 diabetes can participate in extreme altitude mountaineering. However, there are significant risks associated with this activity, including hypoglycaemia, ketoacidosis and retinal haemorrhage, with the additional difficulties in assessing glycaemic control due to meter inaccuracy at high altitude. People with Type 1 diabetes must be carefully counselled before attempting extreme altitude mountaineering. Diabet. Med. 18, 749,755 (2001) [source] Ethnic and Sex Differences in Ownership of Preventive Health Equipment Among Rural Older Adults With DiabetesTHE JOURNAL OF RURAL HEALTH, Issue 4 2007Ronny A. Bell PhD ABSTRACT:,Context:Diabetes self-management is important for achieving successful health outcomes. Different levels of self-management have been reported among various populations, though little is known about ownership of equipment that can enhance accomplishment of these tasks.Purpose:This study examined diabetes self-management equipment ownership among rural older adults.Methods:Participants included African American, American Indian, and white men and women 65 years of age and older. Data included equipment ownership overall and by ethnicity and sex across diabetes self-management domains (glucose monitoring, foot care, medication adherence, exercise, and diet). Associations between equipment ownership and demographic and health characteristics were assessed using logistic regression.Findings:Equipment ownership ranged from 85.0% for blood glucose meters to less than 11% for special socks, modified dishes, and various forms of home exercise equipment. Equipment ownership was associated with ethnicity, living arrangements, mobility, poverty status, and formal education.Conclusions:Rural older adults with diabetes are at risk because they lack equipment to perform some self-management tasks. Providers should be sensitive to and assist patients in overcoming this barrier. [source] | ||||||||||
