DreamTel; Diabetes risk evaluation and management tele-monitoring study protocol.

BACKGROUND: The rising prevalence of type 2 diabetes underlines the importance of secondary strategies for the prevention of target organ damage. While access to diabetes education centers and diabetes intensification management has been shown to improve blood glucose control, these services are not available to all that require them, particularly in rural and northern areas. The provision of these services through the Home Care team is an advance that can overcome these barriers. Transfer of blood glucose data electronically from the home to the health care provider may improve diabetes management. METHODS AND DESIGN: The study population will consist of patients with type 2 diabetes with uncontrolled A1c levels living on reserve in the Battlefords region of Saskatchewan, Canada. This pilot study will take place over three phases. In the first phase over three months the impact of the introduction of the Bluetooth enabled glucose monitor will be assessed. In the second phase over three months, the development of guidelines based treatment algorithms for diabetes intensification will be completed. In the third phase lasting 18 months, study subjects will have diabetes intensification according to the algorithms developed. DISCUSSION: The first phase will determine if the use of the Bluetooth enabled blood glucose devices which can transmit results electronically will lead to changes in A1c levels. It will also determine the feasibility of recruiting subjects to use this technology. The rest of the Diabetes Risk Evaluation and Management Tele-monitoring (DreamTel) study will determine if the delivery of a diabetes intensification management program by the Home Care team supported by the Bluetooth enabled glucose meters leads to improvements in diabetes management. TRIAL REGISTRATION: Protocol NCT00325624.

Helping behavior in a rural and an urban setting: professional and casual attire.

This study assessed differences in helping behavior in a rural versus an urban location when directed toward either a professionally or a casually dressed woman. Convenience samples included 40 men and 40 women (10 people of each sex assigned to each condition: rural and professional, rural and casual, urban and professional, and urban and casual). A 21-yr.-old female confederate dropped an envelope near each target helper individually and recorded number of seconds for the target helper to retrieve or point out the dropped item. Analysis indicated significantly faster helping occurred in the rural than in the urban location and that men helped the confederate more often than women. No difference in frequencey of help was related to kind of attire.

Vegetable acceptance by infants: effects of formula flavors.

Individual differences in acceptance patterns are evident as early as the child's first experiences with a particular food. To test hypothesis that the flavor of formula fed to infants modifies their acceptance of some foods, we conducted a within- and between-subjects design study in which two groups of 6- to 11-month-old infants were tested on two separate days. One group was currently feeding a milk-based formula whereas the other was feeding a protein hydrolysate formula, a particularly unpleasant tasting formula to adults that contains similar flavor notes (e.g., sulfur volatiles) with Brassica vegetables such as broccoli. In counterbalanced order, acceptance of pureed broccoli/cauliflower was determined during one test session and pureed carrots on the other. Although there were no group differences in the amount of carrots consumed, hydrolysate infants consumed significantly less broccoli/cauliflower relative to carrots when compared to those who were currently fed milk based formulas (F(1,72 df)=4.43; p=0.04). The mothers of hydrolysate infants were significantly more likely to report that their infants did not enjoy feeding the broccoli/cauliflower (54.2%) when compared to mothers of infants being fed milk-based formulas (28.0%; Chi-Square (1 df)=4.79; p=0.03). Such findings are consistent with prior research that demonstrated a sensory specific satiety following repeated exposure to a particular flavor in milk. We hypothesize that when infants are experiencing a flavor in milk or formula, in the short term, the preference that develops is specific to the context it is experienced in (e.g., milk). Over the longer term, the preference may generalize to other contexts such as solid foods. Hydrolysate infants were also significantly more likely to be judged by their mothers as being more active (F(1,69 df)=3.95; p=0.05) and hesitant (F(1,69 df)=6.55; p=0.01) when compared to those infants who were feeding milk-based formulas, a finding that further supports the hypothesis that mother-child dynamics surrounding early feeding impacts upon mothers' perception of their children's temperament.
