Item Are Burns a Chronic Condition? Examining Patient Reported Outcomes up to 20 Years after Burn Injury – A Burn Model System National Database Investigation(Wolters Kluwer, 2022) Abouzeid, Cailin A.; Wolfe, Audrey E.; Ni, Pengsheng; Carrougher, Gretchen J.; Gibran, Nicole S.; Hammond, Flora M.; Holavanahalli, Radha; McMullen, Kara A.; Roaten, Kimberly; Suman, Oscar; Stewart, Barclay T.; Wolf, Steven; Zafonte, Ross; Kazis, Lewis E.; Ryan, Colleen M.; Schneider, Jeffrey C.; Physical Medicine and Rehabilitation, School of MedicineBackground: People living with burn injury often face long-term physical and psychological sequelae associated with their injuries. Few studies have examined the impacts of burn injuries on long-term health and function, life satisfaction, and community integration beyond 5 years postinjury. The purpose of this study was to examine these outcomes up to 20 years after burn injury. Methods: Data from the Burn Model System National Longitudinal Database (1993-2020) were analyzed. Patient-reported outcome measures were collected at discharge (preinjury status recall) and 5 years, 10 years, 15 years, and 20 years after injury. Outcomes examined were the SF-12/VR-12 Physical Component Summary and Mental Component Summary, Satisfaction with Life Scale, and Community Integration Questionnaire. Trajectories were developed using linear mixed models with repeated measures of outcome scores over time, controlling for demographic and clinical variables. Results: The study population included 421 adult burn survivors with a mean age of 42.4 years. Lower Physical Component Summary scores (worse health) were associated with longer length of hospital stay, older age at injury and greater time since injury. Similarly, lower Mental Component Summary scores were associated with longer length of hospital stay, female sex, and greater time since injury. Satisfaction with Life Scale scores decrease negatively over time. Lower Community Integration Questionnaire scores were associated with burn size and Hispanic/Latino ethnicity. Conclusion: Burn survivors' physical and mental health and satisfaction with life worsened over time up to 20 years after injury. Results strongly suggest that future studies should focus on long-term follow-up where clinical interventions may be necessary.Item Cognitive Dysfunction in Older Breast Cancer Survivors: An Integrative Review(Wolters Kluwer, 2022) Crouch, Adele; Champion, Victoria; Von Ah, Diane; School of NursingBackground: Approximately 60% of the more than 3.8 million breast cancer survivors (BCSs) living in the United States are 60 years or older. Breast cancer survivors experience many symptoms including cognitive dysfunction; however, little is known regarding how age affects these symptoms. Objective: This integrative review was conducted to synthesize the literature on cognitive dysfunction in older BCSs. The purpose was to (1) describe the prevalence of objective and subjective cognitive dysfunctions and (2) examine factors associated with cognitive dysfunction in older BCSs. Methods: Whittemore and Knafl's integrative review methodology was used to examine cognitive dysfunction in BCSs 60 years or older. Results: Twelve quantitative studies were included. Up to 41% of older BCSs experienced cognitive dysfunction on neuropsychological examination, and up to 64% reported cognitive dysfunction on subjective measures pretreatment. Approximately half of older BCSs experienced cognitive decline from pretreatment to posttreatment regardless of cognitive measure. The domains most impacted were memory, executive functioning, and processing speed. Objective and subjective cognitive dysfunctions were associated with age, comorbidities, chemotherapy receipt, sleep, neuropsychological symptom cluster, frailty, and quality of life. Conclusions: Cognitive dysfunction among older BCSs was common both prior to and following treatment. Cognitive dysfunction was associated with multiple factors that are compounded in the aging population and could be detrimental to quality of life and independent living. Implications to practice: Early assessment and intervention by healthcare providers, including nurses, for cognitive dysfunction in older BCSs are essential. Future research should focus on evidence-based interventions for cognitive dysfunction incorporating the unique needs of older BCSs.Item Deficit Accumulation Frailty Trajectories of Older Breast Cancer Survivors and Non-Cancer Controls: The Thinking and Living With Cancer Study(Oxford University Press, 2021) Mandelblatt, Jeanne S.; Zhou, Xingtao; Small, Brent J.; Ahn, Jaeil; Zhai, Wanting; Ahles, Tim; Extermann, Martine; Graham, Deena; Jacobsen, Paul B.; Jim, Heather; McDonald, Brenna C.; Patel, Sunita J.; Root, James C.; Saykin, Andrew J.; Cohen, Harvey Jay; Carroll, Judith E.; Radiology and Imaging Sciences, School of MedicineBackground: We evaluated deficit accumulation and how deficits affected cognition and physical activity among breast cancer survivors and non-cancer controls. Methods: Newly diagnosed nonmetastatic survivors (n = 353) and matched non-cancer controls (n = 355) ages 60-98 years without neurological impairments were assessed presystemic therapy (or at enrollment for controls) from August 2010 to December 2016 and followed for 36 months. Scores on a 42-item index were analyzed in growth-mixture models to determine deficit accumulation trajectories separately and combined for survivors and controls. Multilevel models tested associations between trajectory and cognition (FACT-Cog and neuropsychological tests) and physical activity (IPAQ-SF) for survivors and controls. Results: Deficit accumulation scores were in the robust range, but survivors had higher scores (95% confidence intervals [CI]) than controls at 36 months (0.18, 95% CI = 0.16 to 0.19, vs 0.16, 95% CI = 0.14 to 0.17; P = .001), and averages included diverse deficit trajectories. Survivors who were robust but became frailer (8.8%) had similar baseline characteristics to those remaining robust (76.2%) but experienced a 9.6-point decline self-reported cognition (decline of 9.6 vs 3.2 points; P = .04) and a 769 MET minutes per week decline in physical activity (P < .001). Survivors who started and remained prefrail (15.0%) had self-reported and objective cognitive problems. At baseline, frail controls (9.5%) differed from robust controls (83.7%) on deficits and self-reported cognition (P < .001). Within combined trajectories, frail survivors had more sleep disturbances than frail controls (48.6% [SD = 17.4%] vs 25.0% [SD = 8.2%]; P = .05). Conclusions: Most survivors and controls remained robust, and there were similar proportions on a frail trajectory. However, there were differences in deficit patterns between survivors and controls. Survivor deficit accumulation trajectory was associated with patient-reported outcomes. Additional research is needed to understand how breast cancer and its treatments affect deficit accumulation.Item Group variable selection via convex log-exp-sum penalty with application to a breast cancer survivor study(Wiley Blackwell (Blackwell Publishing), 2015-03) Geng, Zhigeng; Wang, Sijian; Yu, Menggang; Monahan, Patrick O.; Champion, Victoria; Wahba, Grace; Biostatistics, School of Public HealthIn many scientific and engineering applications, covariates are naturally grouped. When the group structures are available among covariates, people are usually interested in identifying both important groups and important variables within the selected groups. Among existing successful group variable selection methods, some methods fail to conduct the within group selection. Some methods are able to conduct both group and within group selection, but the corresponding objective functions are non-convex. Such a non-convexity may require extra numerical effort. In this article, we propose a novel Log-Exp-Sum(LES) penalty for group variable selection. The LES penalty is strictly convex. It can identify important groups as well as select important variables within the group. We develop an efficient group-level coordinate descent algorithm to fit the model. We also derive non-asymptotic error bounds and asymptotic group selection consistency for our method in the high-dimensional setting where the number of covariates can be much larger than the sample size. Numerical results demonstrate the good performance of our method in both variable selection and prediction. We applied the proposed method to an American Cancer Society breast cancer survivor dataset. The findings are clinically meaningful and may help design intervention programs to improve the qualify of life for breast cancer survivors.Item Impact of pain and adverse health outcomes on long-term US testicular cancer survivors(Oxford University Press, 2024) Dinh, Paul C., Jr.; Monahan, Patrick O.; Fosså, Sophie D.; Sesso, Howard D.; Feldman, Darren R.; Dolan, M. Eileen; Nevel, Kathryn; Kincaid, John; Vaughn, David J.; Martin, Neil E.; Sanchez, Victoria A.; Einhorn, Lawrence H.; Frisina, Robert; Fung, Chunkit; Kroenke, Kurt; Travis, Lois B.; Medicine, School of MedicineBackground: No study has quantified the impact of pain and other adverse health outcomes on global physical and mental health in long-term US testicular cancer survivors or evaluated patient-reported functional impairment due to pain. Methods: Testicular cancer survivors given cisplatin-based chemotherapy completed validated surveys, including Patient-Reported Outcomes Measurement Information System v1.2 global physical and mental health, Patient-Reported Outcomes Measurement Information System pain questionnaires, and others. Multivariable linear regression examined relationships between 25 adverse health outcomes with global physical and mental health and pain-interference scores. Adverse health outcomes with a β^ of more than 2 are clinically important and reported below. Results: Among 358 testicular cancer survivors (median age = 46 years, interquartile range [IQR] = 38-53 years; median time since chemotherapy = 10.7 years, IQR = 7.2-16.0 years), median adverse health outcomes number was 5 (IQR = 3-7). A total of 12% testicular cancer survivors had 10 or more adverse health outcomes, and 19% reported chemotherapy-induced neuropathic pain. Increasing adverse health outcome numbers were associated with decreases in physical and mental health (P < .0001 each). In multivariable analyses, chemotherapy-induced neuropathic pain (β^ = -3.72; P = .001), diabetes (β^ = -4.41; P = .037), obesity (β^ = -2.01; P = .036), and fatigue (β^ = -8.58; P < .0001) were associated with worse global mental health, while being married or living as married benefited global mental health (β^ = 3.63; P = .0006). Risk factors for pain-related functional impairment included lower extremity location (β^ = 2.15; P = .04) and concomitant peripheral artery disease (β^ = 4.68; P < .001). Global physical health score reductions were associated with diabetes (β^ = -3.81; P = .012), balance or equilibrium problems (β^ = -3.82; P = .003), cognitive dysfunction (β^ = -4.43; P < .0001), obesity (β^ = -3.09; P < .0001), peripheral neuropathy score (β^ = -2.12; P < .0001), and depression (β^ = -3.17; P < .0001). Conclusions: Testicular cancer survivors suffer adverse health outcomes that negatively impact long-term global mental health, global physical health, and pain-related functional status. Clinically important factors associated with worse physical and mental health identify testicular cancer survivors requiring closer monitoring, counseling, and interventions. Chemotherapy-induced neuropathic pain must be addressed, given its detrimental impact on patient-reported functional status and mental health 10 or more years after treatment.Item Long-term Outcomes of the FRESH START Trial: Exploring the Role of Self-efficacy in Cancer Survivors’ Maintenance of Dietary Practices and Physical Activity(Wiley, 2013-04) Mosher, Catherine E.; Lipkus, Isaac; Sloane, Richard; Snyder, Denise C.; Lobach, David F.; Demark-Wahnefried, WendyBackground: This study examined whether changes in self-efficacy explain the effects of a mailed print intervention on long-term dietary practices of breast and prostate cancer survivors. The relationship between change in self-efficacy and long-term physical activity (PA) also was examined. Methods: Breast and prostate cancer survivors (N = 543) from 39 US states and two Canadian provinces participated in the FRESH START intervention trial. Participants were randomly assigned to receive a 10-month program of mailed print materials on diet and PA available in the public domain or a 10-month program of tailored materials designed to increase fruit and vegetable (F&V) intake, decrease fat intake, and/or increase PA. Changes in self-efficacy for F&V intake and fat restriction were analyzed as potential mediators of the intervention's effects on diet at 2-year follow-up. Because we previously found that change in self-efficacy for PA did not vary by group assignment, the relationship between change in self-efficacy and PA at 2-year follow-up was examined across study conditions. Results: Results suggest that change in self-efficacy for fat restriction partially explained the intervention's effect on fat intake (mean indirect effect = -0.28), and change in self-efficacy for F&V consumption partially explained the intervention's effect on daily F&V intake (mean indirect effect = .11). Change in self-efficacy for fat restriction partially accounted for the intervention's impact on overall diet quality among men only (mean indirect effect = 0.60). Finally, change in self-efficacy for PA predicted PA at 2-year follow-up. Conclusions: Findings suggest that self-efficacy may influence long-term maintenance of healthy lifestyle practices among cancer survivors.Item Long-term survival after traumatic brain injury: a population-based analysis controlled for nonhead trauma(Ovid Technologies (Wolters Kluwer) - Lippincott Williams & Wilkins, 2014-01) Brown, Allen W.; Leibson, Cynthia L.; Mandrekar, Jay; Ransom, Jeanine E.; Malec, James F.; Department of Physical Medicine and Rehabilitation, IU School of MedicineOBJECTIVE: To examine the contribution of co-occurring nonhead injuries to hazard of death after traumatic brain injury (TBI). PARTICIPANTS: A random sample of Olmsted County, Minnesota, residents with confirmed TBI from 1987 through 1999 was identified. DESIGN: Each case was assigned an age- and sex-matched, non-TBI "regular control" from the population. For "special cases" with accompanying nonhead injuries, 2 matched "special controls" with nonhead injuries of similar severity were assigned. MEASURES: Vital status was followed from baseline (ie, injury date for cases, comparable dates for controls) through 2008. Cases were compared first with regular controls and second with regular or special controls, depending on case type. RESULTS: In total, 1257 cases were identified (including 221 special cases). For both cases versus regular controls and cases versus regular or special controls, the hazard ratio was increased from baseline to 6 months (10.82 [2.86-40.89] and 7.13 [3.10-16.39], respectively) and from baseline through study end (2.92 [1.74-4.91] and 1.48 [1.09-2.02], respectively). Among 6-month survivors, the hazard ratio was increased for cases versus regular controls (1.43 [1.06-2.15]) but not for cases versus regular or special controls (1.05 [0.80-1.38]). CONCLUSIONS: Among 6-month survivors, accounting for nonhead injuries resulted in a nonsignificant effect of TBI on long-term mortality.Item Minimizing Post–Intensive Care Syndrome to Improve Outcomes for Intensive Care Unit Survivors(American Association of Critical-Care Nurses, 2022) Mulkey, Malissa A.; Beacham, Pamela; McCormick, Megan A.; Everhart, D. Erik; Khan, Babar; Medicine, School of MedicineTopic: Post-intensive care syndrome is a collection of symptoms that more than half of patients who survive a critical illness, and their family caregivers, experience after the illness. Those symptoms include weakness/ fatigue, sleep disturbances/insomnia, cognitive dysfunction, posttraumatic stress disorder, other mental health conditions, and a lack of effective coping strategies. Clinical relevance: To minimize the risk of a patient developing post-intensive care syndrome, intensive care unit nurses must adopt practices that reduce the severity of disability and optimize patient outcomes. They must also advocate for patients who need additional expert care. Purpose: To describe interventions that critical care nurses can implement to minimize a patient's risk for post-intensive care syndrome. Content covered: This article describes patients who have a high risk of developing post-intensive care syndrome and interventions that are within nurses' purview.Item Neighborhood Disadvantage and Neural Correlates of Threat and Reward Processing in Survivors of Recent Trauma(American Medical Association, 2023-09-05) Webb, E. Kate; Ely, Timothy D.; Rowland, Grace E.; Lebois, Lauren A. M.; van Rooij, Sanne J. H.; Bruce, Steven E.; Jovanovic, Tanja; House, Stacey L.; Beaudoin, Francesca L.; An, Xinming; Neylan, Thomas C.; Clifford, Gari D.; Linnstaedt, Sarah D.; Germine, Laura T.; Bollen, Kenneth A.; Rauch, Scott L.; Haran, John P.; Storrow, Alan B.; Lewandowski, Christopher; Musey, Paul I., Jr.; Hendry, Phyllis L.; Sheikh, Sophia; Jones, Christopher W.; Punches, Brittany E.; Swor, Robert A.; Pascual, Jose L.; Seamon, Mark J.; Datner, Elizabeth M.; Pearson, Claire; Peak, David A.; Merchant, Roland C.; Domeier, Robert M.; Rathlev, Niels K.; Sergot, Paulina; Sanchez, Leon D.; Kessler, Ronald C.; Koenen, Karestan C.; McLean, Samuel A.; Stevens, Jennifer S.; Ressler, Kerry J.; Harnett, Nathaniel G.; Emergency Medicine, School of MedicineImportance: Differences in neighborhood socioeconomic characteristics are important considerations in understanding differences in risk vs resilience in mental health. Neighborhood disadvantage is associated with alterations in the function and structure of threat neurocircuitry. Objective: To investigate associations of neighborhood disadvantage with white and gray matter and neural reactivity to positive and negative stimuli in the context of trauma exposure. Design, setting, and participants: In this cross-sectional study, survivors of trauma who completed sociodemographic and posttraumatic symptom assessments and neuroimaging were recruited as part of the Advancing Understanding of Recovery After Trauma (AURORA) study between September 2017 and June 2021. Data analysis was performed from October 25, 2022, to February 15, 2023. Exposure: Neighborhood disadvantage was measured with the Area Deprivation Index (ADI) for each participant home address. Main outcomes and measures: Participants completed separate threat and reward tasks during functional magnetic resonance imaging. Diffusion-weighted and high-resolution structural images were also collected. Linear models assessed the association of ADI with reactivity, microstructure, and macrostructure of a priori regions of interest after adjusting for income, lifetime trauma, sex at birth, and age. A moderated-mediation model tested whether ADI was associated with neural activity via microstructural changes and if this was modulated by PTSD symptoms. Results: A total of 280 participants (183 females [65.4%]; mean [SD] age, 35.39 [13.29] years) completed the threat task and 244 participants (156 females [63.9%]; mean [SD] age, 35.10 [13.26] years) completed the reward task. Higher ADI (per 1-unit increase) was associated with greater insula (t274 = 3.20; β = 0.20; corrected P = .008) and anterior cingulate cortex (ACC; t274 = 2.56; β = 0.16; corrected P = .04) threat-related activity after considering covariates, but ADI was not associated with reward reactivity. Greater disadvantage was also associated with altered microstructure of the cingulum bundle (t274 = 3.48; β = 0.21; corrected P = .001) and gray matter morphology of the ACC (cortical thickness: t273 = -2.29; β = -0.13; corrected P = .02; surface area: t273 = 2.53; β = 0.13; corrected P = .02). The moderated-mediation model revealed that ADI was associated with ACC threat reactivity via cingulum microstructural changes (index of moderated mediation = -0.02). However, this mediation was only present in individuals with greater PTSD symptom severity (at the mean: β = -0.17; standard error = 0.06, t= -2.28; P = .007; at 1 SD above the mean: β = -0.28; standard error = 0.08; t = -3.35; P < .001). Conclusions and relevance: In this study, neighborhood disadvantage was associated with neurobiology that supports threat processing, revealing associations of neighborhood disadvantage with neural susceptibility for PTSD and suggesting how altered structure-function associations may complicate symptoms. Future work should investigate specific components of neighborhood disadvantage that may be associated with these outcomes.Item A Personalized, Dynamic Physical Activity Intervention Is Feasible and Improves Energetic Capacity, Energy Expenditure, and Quality of Life in Breast Cancer Survivors(Frontiers Media, 2021-04-12) Ballinger, Tarah J.; Althouse, Sandra K.; Olsen, Timothy P.; Miller, Kathy D.; Sledge, Jeffrey S.; Medicine, School of MedicinePurpose: Despite survival and quality of life benefits associated with physical activity, many breast cancer survivors remain inactive. Effective, sustainable interventions must account for individual differences in capability, motivation, and environment. Here, we evaluate the feasibility, mechanics, and efficacy of delivering an individualized, dynamic intervention to increase energetic capacity and energy expenditure. Methods: Stage 0-III breast cancer patients who had completed primary treatment were enrolled. Prior to the intervention, detailed movement data was collected with a wearable GPS and accelerometer for 3 weeks to establish baseline activity. Movement data was collected continuously throughout the 12-week intervention, during which patients received electronically delivered, tailored, dynamic activity "prescriptions", adjusted based on demonstrated individual capability, daily movement in their environment, and progress. Results: Of 66 enrolled, 57 participants began and completed the intervention. The intervention resulted in significant improvements in average steps (+558 steps/day, p = 0.01), energetic capacity measured by power generation on a stationary bicycle (1.76 to 1.99 W/kg lean mass, p < 0.01), and quality of life (FACT-B TOI, 72.8 to 74.8, p = 0.02). The greatest improvement in functional energetic capacity was seen in the lowest performing tertile at baseline (0.76 to 1.12 W/kg, p < 0.01). Discussion: Wearable technology delivery of personalized activity prescriptions based on individual capability and movement behaviors demonstrates feasibility and early effectiveness. The high variability seen in baseline activity and function, as well as in response to the intervention, supports the need for future work in precision approaches to physical activity (NCT03158519).
