Selected AbstractsThe Relationship Between Glycemic Control and Falls in Older AdultsJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 12 2007Joan M. Nelson RN OBJECTIVES: To determine whether glycemic control contributes to fall risk in frail and nonfrail elderly adults with diabetes mellitus. DESIGN: Retrospective, case-controlled design. SETTING: Health maintenance organization in the Denver, Colorado, metropolitan area. PARTICIPANTS: One hundred eleven community-dwelling adults aged 75 and older who receive care through Kaiser Permanente of Colorado. All subjects had been diagnosed with diabetes mellitus, had at least one hemoglobin A1C (HbA1c) measurement in the previous 12 months, and were using oral hypoglycemic medication or insulin to control their diabetes mellitus. MEASUREMENTS: Measurements of risk factors (Vulnerable Elders Survey (VES-13) with a cutpoint of 3 to determine frailty status, self-reported number of falls over the prior 12-month period, HbA1c, fasting low-density lipoprotein cholesterol, average blood pressure, and other factors related to fall risk) were obtained through telephone interview and medical chart review. The outcome measure was falls. RESULTS: Bivariate analyses to assess correlations between falls and risk factors determined that only HbA1c, frailty, and peripheral neuropathy were significantly associated with falls. A stepwise logistic regression determined that fall risk markedly increased when HbA1c was 7 or below, regardless of frailty status. CONCLUSION: In this retrospective study of a convenience sample of frail older adults with diabetes mellitus, tighter glycemic control was associated with greater risk of falling. Prospective studies that further evaluate the risks and benefits of relaxed glucose control in high-risk older adults are needed to confirm this finding.

ABSTRACT This study examined the relative contribution of two dimensions of interior features functional and personal meaning,as predictors of place attachment and self-esteem for ninety-two new retirement community residents housed in independent living apartments or cottages of a recently opened continuing care retirement community (CCRC). Residents were interviewed and facilities observed as part of a multi-disciplinary, collaborative study. Stepwise regression determined which subsets of function and meaning variables respectively operated as the most important, independent predictors for place attachment and self-esteem. Hierarchical regression equations then examined the relationship between function and meaning variables in predicting place attachment and self-esteem, asking: exceeding the effects of function, does meaning add to a feeling of place attachment and self-esteem? For both place attachment and self-esteem, significantly more variance is accounted for when meaning variables are added to function variables. Once functional needs are met, both place attachment and self-esteem are elevated by interior features that have personal meaning. These findings expand the concept of hominess widely used in the design of residential caregiving settings.

Shultz Abstract This study aimed to determine whether absolute sex hormone concentrations predict the magnitude of knee joint laxity changes across the menstrual cycle. Twenty-two females (18,30 years, body mass index ,30), who reported normal menstrual cycles for the previous 6 months were tested daily across one complete menstrual cycle for serum levels of estradiol (E,=,pg/mL), progesterone (P,=,ng/mL), and testosterone (T,=,ng/dL), and knee joint laxity (KLax,=,mm displacement at 134N) measured with a standard knee arthrometer. The change in KLax across the cycle (maximum,minimum), and minimum (early follicular) and peak (postovulatory) hormone concentrations were recorded for each subject. A stepwise linear regression determined if the minimum, peak, or absolute change in hormone concentrations would predict the magnitude of change in KLax across the cycle. KLax changed on average 3.2,±,1.1 mm across the menstrual cycle (range, 1.5,5.3 mm). Minimum levels of E (39.9,±,11.8 pg/mL) and P (0.61,±,0.27 ng/mL), coupled with peak concentrations of E (199.6,±,54.9 pg/mL) and T (22.5,±,10.5 ng/dL) explained 57.6% of the change in KLax across the cycle. Greater absolute changes in KLax were observed in response to peak E and T levels when minimum E concentrations were lower and minimum P concentrations were higher in the early follicular phase. The absolute minimum concentrations of E and P in the early follicular phase appear to be important factors in determining the sensitivity of the knee joint's response to changing hormone levels. © 2005 Orthopaedic Research Society.

Lawrence Abstract,,, Objectives:, To describe oral health-related quality of life (OHRQoL) among New Zealand adults and assess the relationship between clinical measures of oral health status and a well-established OHRQoL measure, controlling for sex, socioeconomic status (SES) and use of dental services. Methods:, A birth cohort of 924 dentate adults (participants in the Dunedin Multidisciplinary Health and Development Study) was systematically examined for dental caries, tooth loss, and periodontal attachment loss (CAL) at age 32 years. OHRQoL was measured using the 14-item Oral Health Impact Profile questionnaire (OHIP-14). The questionnaire also collected data on each study member's occupation, self-rated oral health and reasons for seeing a dental care provider. SES was determined from each individual's occupation at age 32 years. Results:, The mean total OHIP-14 score was 8.0 (SD 8.1); 23.4% of the cohort reported one or more OHIP problems ,fairly often' or ,very often'. When the prevalence of impacts ,fairly/very often' was modeled using logistic regression, having untreated caries, two or more sites with CAL of 4+ mm and 1 or more teeth missing by age 32 years remained significantly associated with OHRQoL, after adjusting for sex and ,episodic' dental care. Multivariate analysis using Poisson regression determined that being in the low SES group was also associated with the mean number of impacts (extent) and the rated severity of impacts. Conclusions:, OHIP-14 scores were significantly associated with clinical oral health status indicators, independently of sex and socioeconomic inequalities in oral health. The prevalence of impacts (23.4%) in the cohort was significantly greater than age- and sex-standardized estimates from Australia (18.2%) and the UK (15.9%). [source] | ||||||||||
