Idiographic Self-Monitoring Instruments to Empower Client Participation and Evaluate Outcome in Intensive Family Preservation Services

Intensive Family Preservation Services seek to reflect the values of focusing on client strengths and viewing clients as colleagues. To promote those values, Intensive Family Preservation Programs should include a systematic form of client self monitoring in their packages of outcome measures. This paper presents a model of idiographic self-monitoring used in time series, single system research design developed for Family Partners, a family preservation program of the School for Contemporary Education in Annandale, Virginia. The evaluation model provides a means of empowering client families to utilize their strengths and promote their status as colleague in determining their own goals, participating in the change process, and measuring their own progress.

THE ISOLATION AND IDENTIFICATION OF O-ACETYLATED SIALIC ACIDS ON HUMAN CELLS (NEURAMINIC ACIDS, PAPER CHROMATOGRAPHY, HUMAN MALIGNANCY, BIOSYNTHETIC LABELING)

Unlike most carbohydrates, sialic acids have a restricted distribution in nature, being present in higher animals and in certain bacteriae. Unfortunately, most studies have not taken into account the fact that the parent sialic acid molecules, N-acetyl(or N-glycolyl)-neuraminic acid can be O-substituted at the 4, 7, 8 and 9 positions, generating many compounds and isomers. The approach and results of this research study demonstrates that proportions of non-, mono-, di-, and tri-O-acetylated sialic acids can be identified and quantitated on normal and malignant human cells. This was accomplished using a paper chromatographic technique to isolate and resolve individual species of non and O-substituted sialic acids. The chemical nature of these O-substituents, as an acetyl ester, was determined on the basis of chemical degradation, enzymatic and fast atom bombardment-mass spectrometry analysis.^ The working hypothesis of this study, that O-acetylated sialic acids are expressed in a restricted manner on normal and malignant cells, was confirmed using the above experimental approach; which identified mono-, di-, and tri-O-acetylated sialic acids on a variety of normal and malignant human cells. These O-acetylated sialic acids were expressed in restricted manner on subpopulations and subcellular fractions of PHL melanoma cells. Aberrant expression of O-acetylated sialic acids was associated with adenocarcinoma of the colon, leading to a nearly complete loss of di- and tri-O-acetylated sialic acids.^ Thus, the ability to isolate and identify biosynthetically radiolabeled O-acetylated sialic acids offers an efficient method of monitoring the expression of O-acetylated sialic acids in biochemical and cellular interactions. Furthermore, the ability to identify abnormal ratios of O-acetylated sialic acids in the human colon, represents a possible diagnostic tool to evaluate and identify patients who may be genetically or culturally predisposed to the development of adenocarcinoma of the colon. ^

The Choosing Healthy Options of Starches (CHOOS) diet and dietary intake self-monitoring for weight loss among adolescent females

Previous research has shown dietary intake self-monitoring, and culturally tailored weight loss interventions to be effective tools for weight loss. Technology can be used to tailor weight loss interventions to better suit adolescents. There is a lack of research to date on the use of personal digital assistants (PDAs) to self-monitor dietary intake among adolescents. The objective of this study was to determine the difference in dietary intake self-monitoring frequency between using a Personal Digital Assistant (PDA) or paper logs as a diet diary in obese adolescent females; and to describe differences in diet adherence, as well as changes in body size and self-efficacy to resist eating. We hypothesized dietary intake self-monitoring frequency would be greater during PDA use than during paper log use. This study was a randomized crossover trial. Participants recorded their diet for 4 weeks: 2 weeks on a PDA and 2 weeks on paper logs. Thirty-four obese females ages 12-20 were recruited for participation. Thirty were included in analyses. Participants recorded more entries/day while using the paper logs (4.10 entries/day ± 0.63) than while using the PDA (3.01 entries/day ±0.75) (p<0.001). Significantly more meals and snacks were skipped during paper log use (0.81/day ± 0.65) than during PDA use (0.23/day ± 0.22) (p=0.011). Changes in body size (BMI, weight, and waist circumference) and self-efficacy to resist eating did not differ significantly between PDA and paper log use. When compared to paper logs, participants felt the PDA was more convenient (p=0.020), looked forward to using the PDA more (p=0.008), and would rather continue using the PDA than the paper logs (p=0.020). The findings of this study indicate use of a PDA as a dietary intake self-monitoring tool among adolescents would not result in increased dietary intake self-monitoring to aid in weight loss. Use of paper logs would result in greater data returned to clinicians, though use of PDAs would likely get adolescents more excited about adhering to recommendations to record their diet. Future research should look at updated communication devices, such as cell phones and other PDAs with additional features, and the role they can play in increasing dietary intake self-monitoring among adolescents.^
