- ItemFeasibility and effectiveness of an automated bilingual text message intervention for weight loss: pilot study.(2013-11-08) Kolodziejczyk, Julia K; Norman, Gregory J; Barrera-Ng, Angelica; Dillon, Lindsay; Marshall, Simon; Arredondo, Elva; Rock, Cheryl L; Raab, Fred; Griswold, William G; Sullivan, Mark; Patrick, KevinBACKGROUND Little is known about the feasibility and acceptability of tailored text message based weight loss programs for English and Spanish language speakers OBJECTIVE This pilot study evaluated the feasibility acceptability and estimated impact of a tailored text message based weight loss program for English and Spanish language speakers The purpose of this pilot study was to inform the development of a full scale randomized trial METHODS There were 20 overweight or obese participants mean age 40 10 SD 8 05 8 20 40 male 9 20 45 Spanish speakers that were recruited in San Diego California from March to May 2011 and evaluated in a one group pre post clinical trial For 8 weeks participants received and responded to 3 5 text messages daily sent from a fully automated text messaging system They also received printed weight loss materials and brief 10 15 minute weekly counseling calls To estimate the impact of the program the primary outcome was weight kg measured during face to face measurement visits by trained research staff Pre and post differences in weight were analyzed with a one way repeated measures analysis of variance Differences by language preference at both time points were analyzed with t tests Body mass index and weight management behaviors also were examined Feasibility and acceptability were determined by recruitment success adherence ie percentage of replies to interactive text messages and attrition and participant satisfaction RESULTS Participants who completed the final assessment N 18 decreased body weight by 1 85 kg F1 17 10 80 P 004 CI 0 66 3 03 2 0 39 At both time points there were no differences in weight by language preference Participants responded to 88 04 986 1120 of interactive text messages attrition rate was 10 2 20 and 94 19 20 of participants reported satisfaction with the program CONCLUSIONS This fully automated text message based weight program was feasible with English and Spanish speakers and may have promoted modest weight loss over an 8 week period TRIAL REGISTRATION Clinicaltrials gov NCT01171586 http clinicaltrials gov ct2 show NCT01171586 Archived by WebCite at http www webcitation org 6Ksr6dl7n

- ItemRealityFlythrough: enhancing situational awareness for medical response to disasters using ubiquitous video.(2006-06-16) McCurdy, Neil J; Griswold, William G; Lenert, Leslie AThe first moments at a disaster scene are chaotic The command center initially operates with little knowledge of hazards geography and casualties building up knowledge of the event slowly as information trickles in by voice radio channels RealityFlythrough is a tele presence system that stitches together live video feeds in real time using the principle of visual closure to give command center personnel the illusion of being able to explore the scene interactively by moving smoothly between the video feeds Using RealityFlythrough medical fire law enforcement hazardous materials and engineering experts may be able to achieve situational awareness earlier and better manage scarce resources The RealityFlythrough system is composed of camera units with off the shelf GPS and orientation systems and a server viewing station that offers access to images collected by the camera units in real time by position orientation In initial field testing using an experimental mesh 802 11 wireless network two camera unit operators were able to create an interactive image of a simulated disaster scene in about five minutes
- ItemA text message-based intervention for weight loss: randomized controlled trial.(2009-01-14) Patrick, Kevin; Raab, Fred; Adams, Marc A; Dillon, Lindsay; Zabinski, Marian; Rock, Cheryl L; Griswold, William G; Norman, Gregory JBACKGROUND To our knowledge no studies have evaluated whether weight loss can be promoted in overweight adults through the use of an intervention that is largely based on daily SMS Short Message Service text and MMS Multimedia Message Service small picture messages transmitted via mobile phones OBJECTIVE This paper describes the development and evaluation of a text message based intervention designed to help individuals lose or maintain weight over 4 months METHODS The study was a randomized controlled trial with participants being exposed to one of the following two conditions lasting 16 weeks 1 receipt of monthly printed materials about weight control 2 an intervention that included personalized SMS and MMS messages sent two to five times daily printed materials and brief monthly phone calls from a health counselor The primary outcome was weight at the end of the intervention A mixed model repeated measures analysis compared the effect of the intervention group to the comparison group on weight status over the 4 month intervention period Analysis of covariance ANCOVA models examined weight change between baseline and 4 months after adjusting for baseline weight sex and age RESULTS A total of 75 overweight men and women were randomized into one of the two groups and 65 signed the consent form completed the baseline questionnaire and were included in the analysis At the end of 4 months the intervention group n 33 lost more weight than the comparison group 1 97 kg difference 95 CI 0 34 to 3 60 kg P 02 after adjusting for sex and age Intervention participants adjusted average weight loss was 2 88 kg 3 16 At the end of the study 22 of 24 92 intervention participants stated that they would recommend the intervention for weight control to friends and family CONCLUSIONS Text messages might prove to be a productive channel of communication to promote behaviors that support weight loss in overweight adults
- ItemA wireless first responder handheld device for rapid triage, patient assessment and documentation during mass casualty incidents.(2007-01-22) Killeen, James P; Chan, Theodore C; Buono, Colleen; Griswold, William G; Lenert, Leslie AMedical care at mass casualty incidents and disasters requires rapid patient triage and assessment acute care and disposition often in the setting of overwhelming numbers of victims limited time and little resources Current systems rely on a paper triage tag on which rescuers and medical providers mark the patient s triage status and record limited information on injuries and treatments administered in the field In this manuscript we describe the design development and deployment of a wireless handheld device with an electronic medical record EMR for use by rescuers responding to mass casualty incidents MCIs and disasters The components of this device the WIISARD First Responder WFR includes a personal digital assistant PDA with 802 11 wireless transmission capabilities microprocessor and non volatile memory and a unique EMR software that replicates the rapidity and ease of use of the standard paper triage tag WFR also expands its functionality by recording real time medical data electronically for simultaneous access by rescuers mid level providers and incident commanders on and off the disaster site WFR is a part of the Wireless Information System for Medical Response in Disasters WIISARD architecture
