Smart City Project Implementations: A Case Study of a Smart Water Metering System in Cary, NC

Smart cities utilize both technology and social coordination to improve a variety of municipal functions. Current research surrounding the success of smart cities and smart city project implementations have produced sets of factors that determine a city’s potential for success. In this case study, these factors are compared to the unique case of the Town of Cary, NC’s implementation of a smart water metering system. By conducting interviews with municipal employees, this research determined that some of these success factors defined in the literature may be over-generalized. Further, this research suggests that more research may be needed on the subject of managing and sustaining the data collected by smart cities in order to maximize the potential data use. This study hopes to lay a foundation for future research in defining smart city success factors and properly managing smart city data use.Master of Science in Information Scienc

Glargine and degludec: solution behaviour of higher dose synthetic insulins

Single, double and triple doses of the synthetic insulins glargine and degludec currently used in patient therapy are characterised using macromolecular hydrodynamic techniques (dynamic light scattering and analytical ultracentrifugation) in an attempt to provide the basis for improved personalised insulin profiling in patients with diabetes. Using dynamic light scattering and sedimentation velocity in the analytical ultracentrifuge glargine was shown to be primarily dimeric under solvent conditions used in current formulations whereas degludec behaved as a dihexamer with evidence of further association of the hexamers (“multi-hexamerisation”). Further analysis by sedimentation equilibrium showed that degludec exhibited reversible interaction between mono- and-di-hexamer forms. Unlike glargine, degludec showed strong thermodynamic non-ideality, but this was suppressed by the addition of salt. With such large injectable doses of synthetic insulins remaining in the physiological system for extended periods of time, in some case 24–40 hours, double and triple dose insulins may impact adversely on personalised insulin profiling in patients with diabetes

Infection grave à Moraxella glucidolytica chez un Chat (aperçu du rôle pathogène des moraxella en Polynésie française)

A l’occasion d’un cas très démonstratif de péritonite subaiguë à Moraxella glucidolytica chez un Chat, ont été étudiées les infections humaines relativement nombreuses dues au même germe en Polynésie Française. En raison du parallélisme de ces infections chez l’homme et chez l’animal, on peut évoquer l’hypothèse d’interférences entre la maladie animale et la maladie humaine et le rôle possible des animaux dans la diffusion du germe

Prevalence and risk factors for vaginal Candida colonization in women with type 1 and type 2 diabetes

BACKGROUND: Diabetes mellitus increases the rate of vaginal colonization and infection with Candida species METHODS: We surveyed women with diabetes receiving care at either an urban or suburban diabetes clinic to examine the relationship between vaginal Candida colonization, diabetes type and duration, and HbA(1c) level. 101 participants completed the self-administered questionnaire and self-collected a vaginal swab for Candida culture. Candida colonization was similar by age and race. RESULTS: Type 1 diabetics were three times as likely as type 2 diabetics to be colonized with any Candida species (OR = 3.4; 95% CI: 1.03, 11.41; p = 0.04); even after adjusting for abnormal HbA(1c), which had an independent effect (OR = 1.4; 95% CI: 1.04, 1.76; p = 0.02). Recent antibiotic use (OR = 4.5; 95% CI: 1.18, 16.79; p = 0.03), lifetime history of chlamydia (OR = 5.8; 95% CI: 1.09, 30.54; p = 0.04), and performing oral sex during the past 2 weeks (OR = 4.9; 95% CI:0.84, 28.27; p = 0.08) were also associated with Candida carriage after adjusting for diabetic type and abnormal HbA(1c). C. albicans was isolated from the majority of colonized type 1 participants (56%), while C. glabrata was the most common isolate among colonized type 2 participants (54%). CONCLUSIONS: Improving glucose control and possibly modifying sexual behavior may reduce risk of Candida colonization, and potentially symptomatic infection, among women with diabetes

A Decrease in Glucose Variability Does Not Reduce Cardiovascular Event Rates in Type 2 Diabetic Patients After Acute Myocardial Infarction: A reanalysis of the HEART2D study

To assess the effect of intraday glucose variability (GV) on cardiovascular outcomes in a reanalysis of Hyperglycemia and Its Effect After Acute Myocardial Infarction on Cardiovascular Outcomes in Patients With Type 2 Diabetes Mellitus (HEART2D) study data. Type 2 diabetic patients after acute myocardial infarction were randomized to an insulin treatment strategy targeting postprandial (PRANDIAL; n = 557) or fasting/interprandial (BASAL; n = 558) hyperglycemia. GV was calculated as mean amplitude of glycemic excursions (MAGE), mean absolute glucose (MAG) change, and SD. The PRANDIAL strategy resulted in an 18% lower MAG than BASAL (mean [SEM] difference 0.09 [0.04] mmol/L/h, P = 0.02). In addition, MAGE and SD were lower in the PRANDIAL group, however, not significantly. HbA(1c) levels and cardiovascular event rates were comparable between groups. A PRANDIAL strategy demonstrated lower intraday GV vs. a BASAL strategy with similar overall glycemic control but did not result in a reduction in cardiovascular outcomes. This does not support the hypothesis that targeting GV would be beneficial in reducing subsequent secondary cardiovascular event

Profile of patients in private home care who developed ventilator-associated pneumonia

ABSTRACT Objectives: to analyze the profile and clinical outcomes of patients who developed Ventilator-Associated Pneumonia (VAP) in private home care and to compare the incidence with national data. Methods: this was a retrospective study with data collected from July 2021 to June 2022 from patient records at a private clinic. Patients using intermittent ventilation or without ventilatory support were excluded. Results: the utilization rate of mechanical ventilation was 15.9%. The incidence density of pneumonia in pediatrics was 2.2 cases per 1000 ventilation-days and in adults was 1.7 cases per 1000 ventilation-days, figures lower than those reported by the National Health Surveillance Agency. There were 101 episodes of pneumonia in 73 patients, predominantly male (65.8%), adults (53.4%), and those with neurological diseases (57.5%). The treatment regimen predominantly took place at home (80.2%), and there was one death. Conclusions: patients in home care showed a low incidence and mortality rate from ventilator-associated pneumonia

Effects of Prandial Versus Fasting Glycemia on Cardiovascular Outcomes in Type 2 Diabetes: The HEART2D trial

OBJECTIVE—Hyperglycemia and Its Effect After Acute Myocardial Infarction on Cardiovascular Outcomes in Patients With Type 2 Diabetes Mellitus (HEART2D) is a multinational, randomized, controlled trial designed to compare the effects of prandial versus fasting glycemic control on risk for cardiovascular outcomes in patients with type 2 diabetes after acute myocardial infarction (AMI)

Severe hypoglycemia during pregnancy: Its frequency and predisposing factors in diabetic women

Severe hypoglycemic episodes, as defined as altered consciousness to the extent that self treatment is impossible, were sought prospectively in pregnant diabetic women. One or more episodes were found in none of 21 gestational onset, insulin-requiring women during their 28 pregnancies but were present in 19 (33%) of the 57 already insulin dependent (Type 1) women during 26 (36%) of their 72 pregnancies. The most common predisposing factors included strict glucose control, anorexia, early morning hours (1200-0900), lack of an adrenergic response and time shortly before the next anticipated meal.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/26085/1/0000161.pd
