Development of a Real-Time Smartphone Solution for the Management of Women With or at High Risk of Gestational Diabetes

Gestational diabetes mellitus (GDM) is defined as new onset or recognition of glucose intolerance in pregnancy. Evidence supports tight blood glucose regulation to prevent adverse maternal and fetal outcomes. Finger-prick blood glucose (BG) testing with frequent clinic review remains the most common method of managing diabetes in pregnancy. The prevalence of GDM is rising globally, pressuring resource-limited services. We have developed an intuitive, interactive, reliable, and accurate management system to record BG measurements and deliver management of GDM remotely. Following an initial scoping phase, a prototype software application was developed using an Android smartphone with BG meter linkage via Bluetooth. A custom website was built for clinician review of the data transmitted by the smartphone. After system refinement, further evaluation was undertaken for usability and reliability in a 48-patient service development project. Women used the system for an average of 13.1 weeks. In all, 19 686 BG measures were transmitted, 98.6% of which had a meal tag. A total of 466 text messages were transmitted. A mean of 30 BG readings per woman per week were transmitted, and 85% of women submitted the minimum requirement of 18 readings per week. We have developed a novel, real-time, smartphone-based BG monitoring management system that allows clinician review of real-time patient-annotated BG results. Results indicate high usage and excellent compliance by women. Robust clinical, economic, and satisfaction evaluations are required. To address these requirements, we are currently conducting a randomized controlled pilot trial.     

Ethnic and cultural determinants influence risk assessment for hepatitis C acquisition

BACKGROUND AND AIM: In the developed world hepatitis C virus (HCV) infection is predominantly associated with sharing contaminated equipment between injecting drug users (IDU). In developing countries inadequately sterilized medical equipment, transmission of infected blood and cultural practices have been implicated. Accurate risk factor assessment is essential for education targeted at risk reduction in culturally diverse populations. METHODS: Ninety Australian-born Caucasians and 72 South-east Asian (SEA) HCV patients attending a Melbourne hospital liver clinic completed a questionnaire which assessed risk factor profile, perceived risk factors, knowledge of risk factors and methods to minimize transmission. Medical records were audited to identify doctor assessment of risk factors. RESULTS: Risk factors in Caucasians were IDU, body piercing and tattooing (89%, 47% and 32%, respectively). Risk factors in SEA patients were injection therapy, dental therapy and surgery (89%, 70% and 38%, respectively). Most Caucasian patients (94%) correctly identified their mode of acquisition compared with 33% of SEA patients (P < 0.0001). Accurate risk factor documentation in medical records was more common in Caucasians (96 vs 32%; P < 0.0001). The majority of patients identified blood-to-blood and sexual/vertical transmission as important modes of acquisition. However, 33% of SEA patients believed transmission occurred through food, water and poor hygiene and 80% did not identify therapeutic injection or traditional medical practices as risk factors. Education provided to SEA patients did not address less well established routes of transmission. CONCLUSIONS: Ethnicity influences perception and knowledge of risk factors. Improved assessment of risk factors in high-risk ethnic groups is needed. Education should be culturally appropriate and address the concerns of all populations with HCV.     

Secretin Provocation: Gastrin Results in Various Clinical Situations

Our previous secretin provocation studies in normal volunteers and unoperated duodenal ulcer patients suggested that the gastrin rise in gastrinoma may be an exaggeration of the normal response rather than paradoxical. We report further studies in various clinical settings having normogastrinemia (normal, n = 17; unoperated duodenal ulcer, n = 13; primary hyperparathyroidism, n = 7) and hypergastrinemia (postvagotomy, n = 5; hypochlorhydria, n = 7; achlorhydria, n = 10; chronic renal failure, n = 10; gastrinoma, n = 5). Under all nongastrinoma conditions, there were similar gastrin rises of 9-19% between 2 and 5 min after bolus intravenous GIH secretin (2 CU/kg), which fell to baseline by 8 min, except for chronic renal failure. In chronic renal failure, gastrin remained elevated from 7 to 30 min and was significantly different (p less than 0.05) at 10-30 min compared to all other nongastrinoma conditions except hyperparathyroidism. Peak rises occurred within 5 min in all entities, but only three gastrinoma patients had positive secretin provocation tests by the predefined criterion of a gastrin rise greater than 200 pg/ml. The results of secretin provocation in various clinical entities with and without hypergastrinemia further support the hypothesis that the gastrin rise in gastrinoma is an exaggeration of the normal response. The prolonged gastrin rise seen in chronic renal failure may be due to altered renal clearance, inasmuch as other hypergastrinemic states had responses similar to normal and duodenal ulcer.

Reactivation of silent rRNA genes by simian virus 40 in human-mouse hybrid cells.

Mouse-human hybrid cells were used to study the ability of simian virus 40 to regulate the expression of rRNA genes in vivo. In these hybrid cells, only the rRNA genes of the dominant species are expressed; the genes for the rRNA of the recessive species are silent. Simian virus 40 infection of these hybrids led to the production of two distinct 28S rRNA species as analyzed by agarose/2.4% polyacrylamide gel electrophoresis. These species were identified as human and mouse rRNAs. This result was confirmed by histochemical studies which indicated that the nucleolus organizer regions of both mouse and human chromosomes were actively synthesizing rRNA in the virus-infected hybrid cells. These results indicate that simian virus 40 infection can induce the expression of otherwise silent rRNA genes.
