Abstract
The Drosophila polarity protein Crumbs is essential for the establishment and growth of the apical domain in epithelial cells. The protein Yurt limits the ability of Crumbs to promote apical membrane growth, thereby defining proper apical/lateral membrane ratio that is crucial for forming and maintaining complex epithelial structures such as tubes or acini. Here, we show that Yurt also increases Myosin-dependent cortical tension downstream of Crumbs. Yurt overexpression thus induces apical constriction in epithelial cells. The kinase aPKC phosphorylates Yurt, thereby dislodging the latter from the apical domain and releasing apical tension. In contrast, the kinase Pak1 promotes Yurt dephosphorylation through activation of the phosphatase PP2A. The Pak1–PP2A module thus opposes aPKC function and supports Yurt-induced apical constriction. Hence, the complex interplay between Yurt, aPKC, Pak1, and PP2A contributes to the functional plasticity of Crumbs. Overall, our data increase our understanding of how proteins sustaining epithelial cell polarization and Myosin-dependent cell contractility interact with one another to control epithelial tissue architecture.

Abstract
STUDY DESIGN A process evaluation of a clinical trial. OBJECTIVES To describe the roles fulfilled by peer health coaches (PHCs) with spinal cord injury (SCI) during a randomized controlled trial research study called 'My Care My Call', a novel telephone-based, peer-led self-management intervention for adults with chronic SCI 1+ years after injury. SETTING Connecticut and Greater Boston Area, MA, USA. METHODS Directed content analysis was used to qualitatively examine information from 504 tele-coaching calls, conducted with 42 participants with SCI, by two trained SCI PHCs. Self-management was the focus of each 6-month PHC-peer relationship. PHCs documented how and when they used the communication tools (CTs) and information delivery strategies (IDSs) they developed for the intervention. Interaction data were coded and analyzed to determine PHC roles in relation to CT and IDS utilization and application. RESULTS PHCs performed three principal roles: Role Model, Supporter, and Advisor. Role Model interactions included CTs and IDSs that allowed PHCs to share personal experiences of managing and living with an SCI, including sharing their opinions and advice when appropriate. As Supporters, PHCs used CTs and IDSs to build credible relationships based on dependability and reassuring encouragement. PHCs fulfilled the unique role of Advisor using CTs and IDSs to teach and strategize with peers about SCI self-management. CONCLUSION The SCI PHC performs a powerful, flexible role in promoting SCI self-management among peers. Analysis of PHC roles can inform the design of peer-led interventions and highlights the importance for the provision of peer mentor training.

Abstract
Sarcopenia and frailty often co-exist and both have physical function impairment as a core component. Yet despite the urgency of the problem, the development of pharmaceutical therapies for sarcopenia and frailty has lagged, in part because of the lack of consensus definitions for the two conditions. A task force of clinical and basic researchers, leaders from the pharmaceutical and nutritional industries, and representatives from non-profit organizations was established in 2012 with the aim of addressing specific issues affecting research and clinical activities on frailty and sarcopenia. The task force came together on April 22, 2015 in Boston, Massachusetts, prior to the International Conference on Frailty and Sarcopenia Research (ICFSR). The theme of this meeting was to discuss challenges related to drugs designed to target the biology of frailty and sarcopenia as well as more general questions about designing efficient drug trials for these conditions. The present article reports the results of the task force's deliberations based on available evidence and preliminary results of ongoing activities. Overall, the lack of a consensus definition for sarcopenia and frailty was felt as still present and severely limiting advancements in the field. However, agreement appears to be emerging that low mass alone provides insufficient clinical relevance if not combined with muscle weakness and/or functional impairment. In the next future, it will be important to build consensus on clinically meaningful functional outcomes and test/validate them in long-term observational studies.

Abstract
OBJECTIVES The Home Care Satisfaction Measure (HCSM) is an easy to administer, psychometrically sound instrument based on consumer-defined notions of satisfaction, including perspectives of ethnic minorities. The HCSM provides an overall home care satisfaction score and subscale scores for 5 common services, all on a 0-100 scale. METHODS Focus groups with African American, Hispanic, and non-Hispanic White older adults were audiotaped. Tapes were transcribed and analyzed with grounded theory methods. Correlational and common factor analyses were conducted to select items, and the instrument was field tested with 228 frail, low-income, older home care recipients. RESULTS Test-retest reliabilities ranged from .68 to .88, with high internal consistency reliabilities. Substantial concurrent validity was achieved for subscale and overall HCSM scores. Home care satisfaction was not related to gender, age or race but was negatively associated with physical disability. Significant social desirability effects were found. DISCUSSION In the increasingly important area of home care, the HCSM is the first measure developed on the basis of the views of older consumers that also meets standard psychometric criteria. The HCSM provides a consumer-based indicator of quality and can be used to examine changes in satisfaction over time and differences among providers or within a single agency.

Abstract
BACKGROUND AND PURPOSE Simple, practical and reliable clinical balance outcome measures are needed to assess baseline status and response to treatment in older people. The reliability of the clinical measures used in this testing protocol had not been determined for this population. This study assessed the inter-rater reliability of three commonly used clinical measures of balance: one leg standing, tandem gait and functional reach. METHOD Two samples of older people were used: (1) non-disabled and (2) disabled community dwellers. All testing was performed in a single session by two trained examiners according to a standardized protocol. Intra-class correlations were calculated comparing the means of each clinical balance test for Examiner 1 with Examiner 2. RESULTS Reliability coefficients were 0.75 for one leg standing, 0.73 for functional reach, and 0.31 for tandem gait for the non-disabled sample. Reliability coefficients were 0.85 for one leg standing, 0.79 for functional reach, and 0.62 for tandem gait for the disabled sample. CONCLUSIONS These findings for the one leg standing and functional reach testing protocols in disabled and non-disabled older people can be used as outcome measures. Further study should be directed towards improving the reliability of the tandem gait test for use with older people.

Abstract
A randomized, single-blind controlled trial was conducted to test the efficacy of a community-based group intervention to reduce fear of falling and associated restrictions in activity levels among older adults. A sample of 434 persons age 60+ years, who reported fear of falling and associated activity restriction, was recruited from 40 senior housing sites in the Boston metropolitan area. Data were collected at baseline, and at 6-week, 6-month, and 12-month follow-ups. Compared with contact control subjects, intervention subjects reported increased levels of intended activity (p < .05) and greater mobility control (p < .05) immediately after the intervention. Effects at 12 months included improved social function (p < .05) and mobility range (p < .05). The intervention had immediate but modest beneficial effects that diminished over time in the setting with no booster intervention.

Abstract
With a sample survey (N = 266) of elderly adults residing in six housing developments in Massachusetts, we used logistic regression to: (a) identify covariates of fear of falling among all subjects and (b) identify covariates of activity curtailment among the subset of subjects who were afraid of falling. Fifty-five percent of respondents were afraid of falling; of those who were afraid, 56% had curtailed activity due to this fear. Factors associated with fear of falling were: being female, having had previous falls, and having fewer social contacts. Factors associated with activity curtailment among those who were afraid were: not communicating about falls; having less social support; and knowing someone who had fallen. Falls history appears an important contributor to fear of falling, whereas the impact of this fear on activities appears more a function of social support. These findings suggest different strategies for the primary and secondary prevention of fear of falling.

Abstract
A new instrument was developed to assess the role of fear of falling in activity restriction. The instrument assesses fear of falling during performance of 11 activities, and gathers information about participation in these activities as well as the extent to which fear is a source of activity restriction. The instrument demonstrated good internal consistency reliability and showed convergent validity with other fear of falling measures. Concurrent (empirical) validity was demonstrated in that the scale was effective in differentiating among those who were expected to be afraid vs. not afraid of falling. Criterion validity was examined in relation to quality of life variables. Fear of falling was shown to be related to lower quality of life, even when controlling for related background factors. One advantage of this measure over existing measures is the possibility for differentiating fear of falling that leads to activity restriction from fear of falling that accompanies activity. This may provide useful information for those interested in treating fear of falling of promoting activity among the elderly.

Abstract
OBJECTIVE The analyses presented in this article were intended to seek more fine-grained impairment-specific dimensions beyond the motor and cognitive dimensions of the Functional Independence Measure (FIMSM). DESIGN The study used factor analysis within 20 categories of impairment to test the hypotheses that FIM items can be grouped according to functional areas of the body and that these item groupings differ depending on the patient's impairment. PATIENTS Data from 93,829 patients discharged in 1992 from 252 free-standing rehabilitation hospitals and units were obtained from the Uniform Data System for Medical Rehabilitation. RESULTS In 18 of 20 impairment categories, factor analyses of patients admission FIM scores showed impairment-specific FIM dimensions. Four impairments had a 3-dimensional factor structure, and 14 had a 4-dimensional structure. The impairment-specific dimensions were always nested within the motor-FIM subscale. Reliability coefficients for subscales based on these dimensions ranged from .74 to .97. The subscales appear to cluster FIM items by the area of body involved, neurological level, or relative energy consumption. CONCLUSION The FIM can be viewed as a multilayered multidimensional measure of human function. The impairment-specific dimensions, at an intermediate layer, provide insight about the causal linkage between the impairment and resultant patterns of disability. Impairment-specific subscales are relevant to those clinical or research applications where the type of disability needs to be more closely related to impairment.

Abstract
BACKGROUND In accordance with the U.S. Preventive Services Task Force recommendations, the current pilot study tests the feasibility and efficacy of a physician-delivered physical activity counseling intervention. METHODS A sequential comparison group design was used to examine change in self-reported physical activity between experimental (counseling and self-help materials) and control (usual care) patients at base-line and 6 weeks after the initial office visit. Patients in both groups were contacted by telephone 2 weeks after their office visit and asked about the physical activity counseling at their most recent physician visit. Experimental patients also received a follow-up appointment to discuss physical activity with their physician 4 weeks after their initial visit. RESULTS Counseling was feasible for physicians to do and produced short-term increases in physical activity levels. Both groups increased their physical activity, but the increase in physical activity was greater for patients who reported receiving a greater number of counseling messages. CONCLUSIONS Physician-delivered physical activity interventions may be an effective way to achieve wide-spread improvements in the physical activity of middle-aged and older adults.

Abstract
OBJECTIVE The analysis presented here evaluated the psychometric properties of the Functional Independence Measure (FIM) as a summated rating scale within context of the 20 impairment categories of the FIM-Function Related Group (FIM-FRG) system. DESIGN This study involved a cross-sectional analysis of patient records, utilizing factor analysis and techniques of multitrait scaling to verify the summative properties of the motor and cognitive dimensions of the FIM and to study the statistical properties of admission FIM scores. PATIENTS Included were a total of 93.829 patients discharged from 252 freestanding rehabilitation hospitals and units during calendar year 1992. Cases were excluded that had missing or out-of-range values or atypical lengths of stay. These criteria were developed previously in conjunction with an expert clinical panel and confirmed through statistical analyses. RESULTS Factor analyses supported the motor and cognitive dimensions across all 20 impairment categories. The resulting subscales exceeded minimum criteria for item internal consistency in 96.9% of tests and item discriminant validity in 100% of tests. Reliability coefficients for each impairment category for both subscales ranged from .86 to .97. There were no major ceiling effects, but patients in certain impairment categories were unable to climb stairs at admission. CONCLUSION The psychometric properties of the summated FIM compare favorably to most standardized health measures used in medical practice. Findings provide support for the motor and cognitive subscales as used in the FIM-FRGs. As a unidimensional scale, the FIM quantifies care burden. Split into the motor and cognitive (as used in the FIM-FRGs) it distinguishes physical disabilities from those arising from communication or cognitive difficulties.

Abstract
OBJECTIVES Increased tooth retention coupled with increased numbers of older adults means that the actual number of teeth at risk to dental disease will increase sharply. Whether this increase in the number of teeth will translate into more disease and utilization in unknown. The purpose of this study was to test this "more teeth, therefore more dental disease" theory using cross-sectional data. METHODS In-home personal interview and oral examination data were obtained on a probability sample of elders aged 70 years and older living in the six New England states using the Medicare beneficiary list as a sampling frame. Data on dental utilization, number of teeth, dental caries, and periodontal disease were included in the current analysis. RESULTS Analysis of variance on subjects with 1-10 (Group 1), 11-24 (Group 2), and 25-32 (Group 3) teeth show that the extent of bleeding on probing, pocket depth, and loss of attachment all increase as numbers of teeth increase. Similarly, a greater number of restored coronal and root surfaces were found in Group 3 relative to the other two groups. Mean numbers of decayed and filled coronal surfaces were 8.4 in Group 1.33.0 in Group 2, and 50.3 in Group 3. In contrast, unrestored coronal and root surface were significantly higher in Group 1 (mean root DS = 1.3) than Group 3 (mean root DS = 0.3). Utilization patterns of those with successful aging dentitions (Group 3) show that they are visiting dentists more frequently than the compromised group (Group 1). CONCLUSIONS These cross-sectional data obtained from a probability sample of New England elders show that subjects who retained higher numbers of teeth have more periodontal disease and dental caries experience, and visit the dentist more frequently.

Abstract
This study was conducted to evaluate the effect of automated telephone patient monitoring and counseling on patient adherence to antihypertensive medications and on blood pressure control. A randomized controlled trial was conducted in 29 greater Boston communities. The study subjects were 267 patients recruited from community sites who were >or= 60 years of age, on antihypertensive medication, with a systolic blood pressure (SBP) of >or= 160 mm Hg and/or a diastolic blood pressure (DBP) of >or= 90 mm Hg. The study compared subjects who received usual medical care with those who used a computer-controlled telephone system in addition to their usual medical care during a period of 6 months. Weekly, subjects in the telephone group reported self-measured blood pressures, knowledge and adherence to antihypertensive medication regimens, and medication side-effects. This information was sent to their physicians regularly. The main study outcome measures were change in antihypertensive medication adherence, SBP and DBP during 6 months, satisfaction of patient users, perceived utility for physicians, and cost-effectiveness. The mean age of the study population was 76.0 years; 77% were women; 11% were black. Mean antihypertensive medication adherence improved 17.7% for telephone system users and 11.7% for controls (P = .03). Mean DBP decreased 5.2 mm Hg in users compared to 0.8 mm Hg in controls (P = .02). Among nonadherent subjects, mean DBP decreased 6.0 mm Hg for telephone users, but increased 2.8 mm Hg for controls (P = .01). For telephone system users, mean DBP decreased more if their medication adherence improved (P = .03). The majority of telephone system users were satisfied with the system. Most physicians integrated it into their practices. The system was cost-effective, especially for nonadherent patient users. Therefore, weekly use of an automated telephone system improved medication adherence and blood pressure control in hypertension patients. This system can be used to monitor patients with hypertension or with other chronic diseases, and is likely to improve health outcomes and reduce health services utilization and costs.

Abstract
BACKGROUND To better define nutritional risk among older Americans, a cross-sectional study of nutrition and health status was carried out in a probability sample of 1,156 free-living elders, 70 years and older, from 67 communities representing urban and rural areas of the six New England states. METHOD All participants completed telephone interviews concerning demographic and health characteristics. A subsample of 1,156 individuals underwent in-home assessments of oral health, anthropometrics, and nutritional risk, including a 24-hour dietary recall. RESULTS Nutrition-related problems were common and diverse among New England elders. Some 41.5% were overweight (BMI > 27 kg/m2), and mean dietary lipid intakes were considerably above recommended levels (Healthy People 2000 (National Health Promotion and Disease Prevention Objectives). Some 16% were underweight (BMI < 22 kg/m2), mean dietary calcium levels were low, and about 28% of older individuals failed to consume adequate levels (> 75% the Recommended Dietary Allowance for persons 51 years and older) for three or more key nutrients. Persons of advanced age or who smoked were more likely to have high dietary lipid intakes or less than adequate nutrient intake. Higher dietary lipid levels were also more common among men and individuals who lived with others. Low nutrient intake was more prevalent in those with lower educational attainment and dental problems. CONCLUSION Nutrition policies and multidisciplinary interventions for older Americans need to emphasize the spectrum of nutritional problems in the elderly, including dietary excesses and potential nutrient deficiencies. The demographic and life-style characteristics that place older individuals at high nutritional risk need to be considered, particularly advanced age, gender, living situation, smoking, dietary behavior, educational attainment, and dental health.

Abstract
An in-home examination of a probability sample of elders aged 70 and older living in the six New England states was conducted to estimate the prevalence and extent of root caries. Oral examinations were conducted by the visual-tactile method using a portable lamp, explorer, and a mouth mirror. Fifty-two percent of the study participants showed root caries experience and 22 percent had untreated root caries. In contrast to previous studies, this analysis showed that buccal root surfaces were no more likely than proximal surfaces to be affected by root caries. Logistic regression analysis showed that gingival recession and number of teeth were positively associated with root caries, while better oral hygiene maintenance and regular dental visits were negatively associated with root caries lesions (all factors: P < .05). The prevalence of root caries was found to increase with higher numbers of teeth except for a minority subgroup--i.e., those who retained 25 or more teeth. This study provides much-needed data on prevalence and extent of root caries in a probability sample of the oldest old in an entire region of the United States.

Abstract
A computerized dental data recording system (DDRS) was developed for the New England Elder Dental Study to improve data quality and increase field staff efficiency. The DDRS displays video screens similar to traditional paper forms to record data on coronal and root caries, dentate and denture status, subacute bacterial endocarditis screening, gingival bleeding, calculus, and periodontal attachment level. DDRS provides facilities for date and exam-component time tracking, on-line contextual comments, random record retrieval, editing, data backup, and data output in various data formats. This study compared the DDRS with a paper-form system for data entry accuracy. Dental caries and periodontal disease measurement data from 38 subjects were recorded on paper forms and independently entered using DDRS. The DDRS identified 150 illogical data errors, 39 inconsistent data errors, 7 invalid data and 34 miscellaneous data errors. Four technicians with field experience using both paper forms and DDRS reported time savings using DDRS in the field. DDRS has the potential for additional time savings by minimizing the time for data coding, cleaning, and management. Results demonstrate that DDRS could improve the quality of oral epidemiologic data by mandating strict adherence to protocols, preventing errors, and increasing field efficiency.

Abstract
The structure and function of a newly created interdisciplinary Geriatric Consultation Team (GCT) are described. The GCT was introduced on a single medical unit, where consultations were given to 46 consecutive patients aged 75 years and over. The GCT patients had, on the average, 5.5 illnesses and were receiving 3.7 medications. Anemia (50 per cent), were hypoalbuminemia (65 per cent), and elevated blood urea nitrogen (BUN) (58 per cent) were frequent. Functional assessment showed frequent dependence on others for assistance with ambulation (59 per cent), transfers (54 per cent), and dressing (52 per cent); cognitive impairment was found in 52 per cent and clinical depression in 11 per cent of the patients. In comparison with control units, the GCT increased use of physical therapy by 357 per cent, occupational therapy by 390 per cent, and speech therapy by 300 per cent without increasing length of stay. In comparison with control subjects, GCT patients had no decrease in hospital readmission rates (43 per cent) over 10.5 months of follow up. It was concluded that a GCT in an acute-care hospital promotes geriatrics, teaches interdisciplinary teamwork, improves awareness of functional problems of patients, and increases use of rehabilitative services, but does not decrease the high rate of readmission of hospitalized geriatric patients.

Abstract
Providing appropriate health services to the elderly is emerging as one of the major challenges of this decade. Using the theoretical framework developed by Andersen and Aday, this study attempts to improve our understanding of those factors which inhibit or facilitate elders' use of health services. The data come from a 1974 statewide random probability sample of 1,625 noninstitutionalized elders 65 years of age or older living in Massachusetts. Regression analysis is used to study the effects of predisposing, enabling, and need characteristics on the use of five health services: hospitals, physicians, dentists, home care, and ambulatory care. The model explains from 5% to 27% of the variance in health service utilization. Need characteristics, in general, account for most of the explained variance.

Abstract
This study examines the validity of a system of measuring functional status, an important determinant of quality of life. With a group of elderly people who suffer from arthritis, we found that scores in the dimensions of dependence, difficulty, and pain on performance of Activities of Daily Living (ADL) are positively correlated with client reports of joint conditions, ability to deal with their arthritis and attendant problems, and numbers of "good days." Instrument scores do not correlate with professional assessments of clients' joint condition or of their ability to deal with arthritis, although the two professional assessments correlate with each other. Thus it appears that client and professional definitions of joint condition differ; only the clients' definition relates to our measure of functional status.
