Item Anticholinergic Exposure During Rehabilitation: Cognitive and Physical Function Outcomes in Patients with Delirium Superimposed on Dementia(Elsevier, 2015-12) Kolanowski, Ann; Mogle, Jacqueline; Fick, Donna M.; Campbell, Noll; Hill, Nikki; Mulhall, Paula; Behrens, Liza; Colancecco, Elise; Boustani, Malaz; Clare, Linda; Department of Medicine, IU School of MedicineOBJECTIVES: We examined the association between anticholinergic medication exposure and subsequent cognitive and physical function in patients with delirium superimposed on dementia during rehabilitation. We also examined length of stay and discharge disposition by anticholinergic medication exposure. DESIGN: In this secondary analysis we used control group data from an ongoing randomized clinical trial. SETTING/PARTICIPANTS: Participants with delirium and dementia were enrolled at admission to post-acute care. These 99 participants had a mean age of 86.11 (±6.83) years; 67.6% were women; 98% were Caucasian; and 33% were positive for at least one APOE e4 allele. MEASURES: We obtained daily measures of cognitive and physical function using: Digit Span; memory, orientation and attention items from the Montreal Cognitive Assessment; CLOX; the Confusion Assessment Method; and the Barthel Index. Anticholinergic medication exposure was measured weekly using the Anticholinergic Cognitive Burden Scale. RESULTS: Using multilevel models for time we found that greater use of clinically relevant anticholinergic medications in the previous week reduced cognitive and physical function, as measured by Digit Span Backwards and the Barthel index, in the current week. There was no effect of anticholinergic medication use on delirium severity, and APOE status did not moderate any outcomes. Greater use of clinically relevant anticholinergic medications was related to longer length of stay but not discharge disposition. CONCLUSIONS: For vulnerable older adults, anticholinergic exposure represents a potentially modifiable risk factor for poor attention, working memory, physical function, and greater length of stay during rehabilitation.Item Association between Cognitive Function and Physical Function, Frailty, and Quality of Life in Older Breast Cancer Survivors(MDPI, 2024-07-31) Von Ah, Diane; Rio, Carielle Joy; Carter, Allie; Perkins, Susan M.; Stevens, Erin; Rosko, Ashley; Davenport, Ashley; Kalady, Mathew; Noonan, Anne M.; Crouch, Adele; Storey, Susan; Overcash, Janine; Han, Claire J.; Yang, Yesol; Li, Haiying; Saligan, Leorey N.; Biostatistics and Health Data Science, Richard M. Fairbanks School of Public HealthBackground: Older cancer survivors in general are at greater risk for cancer-related cognitive impairment (CRCI), yet few studies have explored its association with health outcomes. This study examined the association between subjective and objective measures of cognitive function and physical function, frailty, and quality of life (QoL) among older breast cancer survivors. Materials and methods: Older breast cancer survivors who reported cognitive concerns completed surveys on patient-reported cognitive function, physical function, frailty, and QoL as well as objective tests of visuospatial working memory and sustained attention. Data were analyzed using descriptive statistics and separate linear regression models. Results: A total of 219 female breast cancer survivors completed the study. Perceived cognitive abilities were associated with better physical function, frailty, and QoL (p ≤ 0.001) while cognitive concerns were negatively related with these metrics (p ≤ 0.001). Poorer visuospatial working memory and sustained attention were linked to increased frailty (p ≤ 0.001-0.01), whereas poorer sustained attention was associated with poorer physical function (p < 0.01). Conclusions: Older breast cancer survivors with perceived cognitive impairment and poorer cognitive performance reported poorer physical functioning, increased frailty, and poorer QoL. These findings underscore the importance of assessing cognitive concerns and their associated outcomes in older breast cancer survivors.Item Comorbidity, cognitive dysfunction, physical functioning, and quality of life in older breast cancer survivors(Springer, 2022-01) Crouch, Adele; Champion, Victoria L.; Von Ah, Diane; School of NursingPurpose: Older breast cancer survivors (BCS) may be at greater risk for cognitive dysfunction and other comorbidities; both of which may be associated with physical and emotional well-being. This study will seek to understand these relationships by examining the association between objective and subjective cognitive dysfunction and physical functioning and quality of life (QoL) and moderated by comorbidities in older BCS. Methods: A secondary data analysis was conducted on data from 335 BCS (stages I-IIIA) who were ≥ 60 years of age, received chemotherapy, and were 3-8 years post-diagnosis. BCS completed a one-time questionnaire and neuropsychological tests of learning, delayed recall, attention, working memory, and verbal fluency. Descriptive statistics and separate linear regression analyses testing the relationship of each cognitive assessment on physical functioning and QoL controlling for comorbidities were conducted. Results: BCS were on average 69.79 (SD = 3.34) years old and 5.95 (SD = 1.48) years post-diagnosis. Most were stage II (67.7%) at diagnosis, White (93.4%), had at least some college education (51.6%), and reported on average 3 (SD = 1.81) comorbidities. All 6 physical functioning models were significant (p < .001), with more comorbidities and worse subjective attention identified as significantly related to decreased physical functioning. One model found worse subjective attention was related to poorer QoL (p < .001). Objective cognitive function measures were not significantly related to physical functioning or QoL. Conclusions: A greater number of comorbidities and poorer subjective attention were related to poorer outcomes and should be integrated into research seeking to determine predictors of physical functioning and QoL in breast cancer survivors.Item Comorbidity, Physical Function, and Quality of Life in Older Adults with Acute Myeloid Leukemia(Springer, 2017-12) Storey, Susan; Gray, Tamryn Fowler; Bryant, Ashley Leak; School of NursingPurpose of review: To describe the pathology, impact of comorbidities, functional limitations, symptoms, and quality of life (QOL) related to treatment of acute myeloid leukemia (AML) in older adults. Recent findings: AML is a rare aggressive hematologic disease that occurs most often in older adults. The prognosis for older patients with AML is markedly worse due to genetic mutations and patient characteristics such as comorbidities and functional limitations. Patient characteristics may influence treatment decisions, as well as impact symptoms, functional ability, health-related outcomes and (QOL). Summary: As the population continues to age, the number of people diagnosed with AML is expected to increase. Better management of comorbidities is imperative to improving QOL and other treatment related outcomes. Prospective, longitudinal and multi-site studies are warranted to further understand the interaction between these characteristics on symptoms, outcomes and QOL.Item Effects of Qigong Exercise on Physical and Psychological Health among African Americans(Sage, 2021-06) Chang, Pei-Shiun; Lu, Yvonne; Nguyen, Chi Mai; Suh, Youngnok; Luciani, Mary; Ofner, Susan; Powell, Savannah; School of NursingInterventions are needed to address physical and psychological health in middle-aged and older African Americans (AAs). The purpose of this pilot study was to evaluate the feasibility and potential benefits of an eight-week Qigong exercise on physical ability and function, balance, frailty, depression and anxiety, and spiritual well-being in AAs using a single-group design. Fifteen AAs with a mean age of 64 years received Qigong exercise over 16 semi-weekly, one-hour sessions. The majority were female (93.3%) and college-level educated (53.3%). Repeat chair stands, physical function, and spiritual well-being improved significantly (p < .05) with effect sizes ranging from .45 to .87. Over 52% of participants showed improved depression scores, fast gait speed, and standing balance. Nearly 42% demonstrated some frailty improvement over baseline. No adverse events were reported. Qigong exercise potentially improves the physical ability and function, and spiritual well-being of AAs and needs further testing in a randomized clinical trial.Item Epigenetic Aging in Older Breast Cancer Survivors and Non-Cancer Controls: Preliminary Findings from the Thinking and Living with Cancer (TLC) Study(Wiley, 2023) Rentscher, Kelly E.; Bethea, Traci N.; Zhai, Wanting; Small, Brent J.; Zhou, Xingtao; Ahles, Tim A.; Ahn, Jaeil; Breen, Elizabeth C.; Cohen, Harvey Jay; Extermann, Martine; Graham, Deena M. A.; Jim, Heather S. L.; McDonald, Brenna C.; Nakamura, Zev M.; Patel, Sunita K.; Root, James C.; Saykin, Andrew J.; Van Dyk, Kathleen; Mandelblatt, Jeanne S.; Carroll, Judith E.; Radiology and Imaging Sciences, School of MedicineBackground: Cancer and its treatments may accelerate aging in survivors; however, research has not examined epigenetic markers of aging in longer term breast cancer survivors. This study examined whether older breast cancer survivors showed greater epigenetic aging than noncancer controls and whether epigenetic aging related to functional outcomes. Methods: Nonmetastatic breast cancer survivors (n = 89) enrolled prior to systemic therapy and frequency-matched controls (n = 101) ages 62 to 84 years provided two blood samples to derive epigenetic aging measures (Horvath, Extrinsic Epigenetic Age [EEA], PhenoAge, GrimAge, Dunedin Pace of Aging) and completed cognitive (Functional Assessment of Cancer Therapy-Cognitive Function) and physical (Medical Outcomes Study Short Form-12) function assessments at approximately 24 to 36 and 60 months after enrollment. Mixed-effects models tested survivor-control differences in epigenetic aging, adjusting for age and comorbidities; models for functional outcomes also adjusted for racial group, site, and cognitive reserve. Results: Survivors were 1.04 to 2.22 years biologically older than controls on Horvath, EEA, GrimAge, and DunedinPACE measures (p = .001-.04) at approximately 24 to 36 months after enrollment. Survivors exposed to chemotherapy were 1.97 to 2.71 years older (p = .001-.04), and among this group, an older EEA related to worse self-reported cognition (p = .047) relative to controls. An older epigenetic age related to worse physical function in all women (p < .001-.01). Survivors and controls showed similar epigenetic aging over time, but Black survivors showed accelerated aging over time relative to non-Hispanic White survivors. Conclusion: Older breast cancer survivors, particularly those exposed to chemotherapy, showed greater epigenetic aging than controls that may relate to worse outcomes. If replicated, measurement of biological aging could complement geriatric assessments to guide cancer care for older women.Item Experience and participation implications of daily enhancement meaningful activity in persons with mild cognitive impairment(2016-04-01) Ellis, Jennifer L.; Arnold, Brent Lee; Lu, Yvonne Yueh-Feng; Altenburger, Peter Andrew; Munk, NikiBackground: Persons with Mild Cognitive Impairment (PwMCI) battle progressive disengagement from personally meaningful activities that results in functional decline. Little is known about PwMCI experience of engaging in meaningful activities and relationships among MCI stage, confidence, depressive symptoms, and function. Daily Engagement of Meaningful Activity (DEMA) is a multicomponent, family-focused, tailored intervention designed to benefit PwMCI and their caregivers by facilitating goal identification, preserve engagement, and support adjustments to cognitive and functional changes. Objectives: The aims of this secondary analysis were to: (i) describe PwMCI experience of engagement in DEMA, (ii) evaluate for potential relationship among MCI stage, confidence, depressive symptoms, activity type, activity performance, physical function and (iii) evaluate ability of select outcomes to predict change in depressive symptoms and physical function, (iv) determine difference between participants when sub-grouped by ICF level. Methods: Mixed methodology was used to conduct a secondary analysis from the parent study. The parent study used a two-group randomized trial involving PwMCI and informal caregivers participating in the Indiana Alzheimer Disease Center DEMA program. Quantitative analysis (dyads: DEMA N=20, Information Support N = 20) examined outcomes at baseline, posttest and follow-up. Analysis employed: (i) Colaizzi's Method of empirical phenomenology to describe PwMCI experience of engagement in activity intervention related to perceptions of changes in confidence, activity performance, and physical function; (ii) Pearson's and Spearman's correlation to ascertain relationship; (iii) Linear regression to model the relationship between explanatory and dependent variables; (iv) Independent t-test to determine significant difference in activities and physical function. Results: Qualitative themes confirm improved awareness, adjustment, problem-solving, confidence and optimized function. Significant correlations were found at baseline and posttest for MCI stage, depressive symptoms, activity type and physical function. At posttest, change in self-rated performance predicted change in depressive symptoms. Additionally, those who engaged in activity at the ICF level of participation demonstrated a significant increase in confidence and physical function. Conclusion: Qualitative themes and quantitative results clearly indicate the positive impact of DEMA. Future research should employ a larger, randomized controlled longitudinal trial to ascertain DEMA impact on physical function, reduction of participation restriction and improved QOL.Item Kinesiophobia Predicts Physical Function and Physical Activity Levels in Chronic Pain-Free Older Adults(Frontiers Media, 2022-04-27) Naugle, Kelly M.; Blythe, Corinthian; Naugle, Keith E.; Keith, NiCole; Riley, Zachary A.; Kinesiology, School of Health and Human SciencesAdvanced aging is associated with a general decline in physical function and physical activity. The current evidence suggests that pain-related fear of movement (i.e., kinesiophobia) is increased in the general older adult population and impacts physical activity levels in patients with chronic pain. However, whether kinesiophobia could impact physical activity and function in relatively healthy, chronic pain-free older adults remain unclear. Thus, the purpose of this study was to examine whether fear of movement due to pain predicted self-reported and objective levels of physical function and physical activity in healthy older adults without chronic pain. Fifty-two older adults were enrolled in this study. The participants completed the International Physical Activity Questionnaire (IPAQ) and wore an accelerometer on the hip for 7 days to measure physical activity. Measures of sedentary time, light physical activity, and moderate to vigorous physical activity were obtained from the accelerometer. Measures of physical function included the Physical Functioning subscale of the Short Form-36, Short Physical Performance Battery (SPPB), the 30-s Chair Stand test, and a maximal isometric hand-grip. The Tampa Scale of Kinesiophobia (TSK) was used to measure fear of movement or re-injury associated with pain. Potential covariates included self-reported activity-related pain and demographics. Hierarchical linear regressions were conducted to determine the relationship of kinesiophobia with levels of physical activity and physical function while controlling for activity-related pain and demographics. TSK scores did not predict self-reported physical activity on the IPAQ. However, TSK scores predicted self-reported physical function (Beta = -0.291, p = 0.015), 30-s Chair Stand test scores (Beta = -0.447, p = 0.001), measures from the SPPB (Gait speed time: Beta = 0.486, p < 0.001; Chair stand time: Beta = 0.423, p = 0.003), percentage of time spent in sedentary time (Beta = 0.420, p = 0.002) and light physical activity (Beta = -0.350, p = 0.008), and moderate to vigorous physical activity (Beta = -0.271, p = 0.044), even after controlling for significant covariates. These results suggest that greater pain-related fear of movement/re-injury is associated with lower levels of light and moderate to vigorous physical activity, greater sedentary behavior, and worse physical function in healthy, chronic pain-free older adults. These findings elucidate the potential negative impact of kinesiophobia in older adults who don't report chronic pain.Item Mobility Impairment in Patients New to Dialysis(Karger, 2020) Moorthi, Ranjani N.; Fadel, William F.; Cranor, Alissa; Hindi, Judy; Avin, Keith G.; Lane, Kathleen A.; Thadhani, Ravi I.; Moe, Sharon M.; Medicine, School of MedicineBackground: Impaired mobility is associated with functional dependence, frailty, and mortality in prevalent patients undergoing dialysis. We investigated risk factors for mobility impairment, (poor gait speed) in patients incident to dialysis, and changes in gait speed over time in a 2-year longitudinal study. Methods: One hundred eighty-three patients enrolled within 6 months of dialysis initiation were followed up 6, 12, and 24 months later. Grip strength, health-related quality of life, and comorbidities were assessed at baseline. Outcomes were (a) baseline gait speed and (b) change in gait speed over time. Gait speed was assessed by 4-meter walk. Multivariate linear regression was used to identify risk factors for low gait speed at baseline. For longitudinal analyses, linear mixed effects modeling with gait speed modeled over time was used as the outcome. Results: Participants were 54.7 ± 12.8 years old, 52.5% men, 73.9% black with mean dialysis vintage of 100.1 ± 46.9 days and median gait speed 0.78 (0.64-0.094) m/s. Lower health utility and grip strength, diabetic nephropathy, and walking aids were associated with lower baseline gait speed. Loss of 0.1 m/s gait speed occurred in 24% of subjects at 1 year. In multivariate mixed effects models, only age, walking aid use, lower health utility, and lower handgrip strength were significantly associated with gait speed loss. Conclusions: In our cohort of incident dialysis patients, overall gait speed is very low and 54.2% of the subjects continue to lose gait speed over 2 years. Older age, lower handgrip strength, and quality of life are risk factors for slowness. Patients at highest risk of poor gait speed can be identified at dialysis initiation to allow targeted implementation of therapeutic options.Item Prevalence, Severity, and Co-Occurrence of SPPADE Symptoms in 31,866 Patients with Cancer(Elsevier, 2023) Kroenke, Kurt; Lam, Veronica; Ruddy, Kathryn J.; Pachman, Deirdre R.; Herrin, Jeph; Rahman, Parvez A.; Griffin, Joan M.; Cheville, Andrea L.; Medicine, School of MedicineObjectives: To examine the prevalence, severity, and co-occurrence of SPPADE symptoms as well as their association with cancer type and patient characteristics. Background: The SPPADE symptoms (sleep disturbance, pain, physical function impairment, anxiety, depression, and low energy /fatigue) are prevalent, co-occurring, and undertreated in oncology and other clinical populations. Methods: Baseline SPPADE symptom data were analyzed from the E2C2 study, a stepped wedge pragmatic, population-level, cluster randomized clinical trial designed to evaluate a guideline-informed symptom management model targeting the six SPPADE symptoms. Symptom prevalence and severity were measured with a 0-10 numeric rating (NRS) scale for each of the six symptoms. Prevalence of severe (NRS ≥ 7) and potential clinically relevant (NRS ≥ 5) symptoms as well as co-occurrence of clinical symptoms were determined. Distribution-based methods were used to estimate the minimally important difference (MID). Associations of cancer type and patient characteristics with a SPPADE composite score were analyzed. Results: A total of 31,886 patients were assessed for SPPADE symptoms prior to, during, or soon after an outpatient medical oncology encounter. The proportion of patients with a potential clinically relevant symptom ranged from 17.5% for depression to 33.4% for fatigue. Co-occurrence of symptoms was high, with the proportion of patients with three or more additional clinically relevant symptoms ranging from 45.2% for fatigue to 68.6% for depression. The summed SPPADE composite score demonstrated good internal reliability (Cronbach's alpha of 0.86), with preliminary MID estimates of 4.1-4.3. Symptom burden differed across several types of cancer but was generally similar across most sociodemographic characteristics. Conclusion: The high prevalence and co-occurrence of SPPADE symptoms in patients with all types of cancer warrants clinical approaches that optimize detection and management.
