Objective: To identify neurocognitive predictors of medical decision-making capacity (MDC) in participants with mild and moderate/severe traumatic brain injury (TBI). Setting: Academic medical center. Participants: Sixty adult controls and 104 adults with TBI (49 mild, 55 moderate/severe) evaluated within 6 weeks of injury. Design: Prospective cross-sectional study. Main Measures: Participants completed the Capacity to Consent to Treatment Instrument to assess MDC and a neuropsychological test battery. We used factor analysis to reduce the battery test measures into 4 cognitive composite scores (verbal memory, verbal fluency, academic skills, and processing speed/executive function). We identified cognitive predictors of the 3 most clinically relevant Capacity to Consent to Treatment Instrument consent standards (appreciation, reasoning, and understanding). Results: In controls, academic skills (word reading, arithmetic) and verbal memory predicted understanding; verbal fluency predicted reasoning; and no predictors emerged for appreciation. In the mild TBI group, verbal memory predicted understanding and reasoning, whereas academic skills predicted appreciation. In the moderate/severe TBI group, verbal memory and academic skills predicted understanding; academic skills predicted reasoning; and academic skills and verbal fluency predicted appreciation. Conclusions: Verbal memory was a predictor of MDC in controls and persons with mild and moderate/severe TBI. In clinical practice, impaired verbal memory could serve as a "red flag" for diminished consent capacity in persons with recent TBI. © 2016 Wolters Kluwer Health, Inc.

Objectives. Using a large, national sample, this study examined perceived caregiving strain and other caregiving factors in relation to all-cause mortality. Method. The REasons for Geographic and Racial Differences in Stroke (REGARDS) study is a population-based cohort of men and women aged 45 years and older. Approximately 12% (n = 3,710) reported that they were providing ongoing care to a family member with a chronic illness or disability. Proportional hazards models were used for this subsample to examine the effects of caregiving status measures on all-cause mortality over the subsequent 5-year period, both before and after covariate adjustment. Results. Caregivers who reported high caregiving strain had significantly higher adjusted mortality rates than both no strain (hazard ratio [HR] = 1.55, p = .02) and some strain (HR = 1.83, p = .001) caregivers. The mortality effects of caregiving strain were not found to differ by race, sex, or the type of caregiving relationship (i.e., spouse, parent, child, sibling, and other). Discussion. High perceived caregiving strain is associated with increased all-cause mortality after controlling for appropriate covariates. High caregiving strain constitutes a significant health concern and these caregivers should be targeted for appropriate interventions. © The Author 2012.

Objective: Older adults receiving Medicare home health services who experience undernutrition may be at increased risk of experiencing adverse outcomes. We sought to identify the association between baseline nutritional status and subsequent health service utilization and mortality over a 1-year period in older adults receiving Medicare home health services. Design: This was a longitudinal study using questionnaires and anthropometric measures designed to assess nutritional status (Mini-Nutritional Assessment) at baseline and health services utilization and mortality status at 6-month and 1-year follow-ups. Setting: Participants were evaluated in their homes. Participants: A total of 198 older adults who were receiving Medicare home health services. Results: Based on Mini-Nutritional Assessment, 12.0% of patients were malnourished, 51.0% were at risk for malnourishment, and 36.9% had normal nutritional status. Based on body mass index, 8.1% of participants were underweight, 37.9% were normal weight, 25.3% were overweight, and 28.8% were obese. Using multivariate binary logistic regression analyses, participants who were malnourished or at risk for malnourishment were more likely to experience subsequent hospitalization, emergency room visit, home health aide use, and mortality for the entire sample and hospitalization and nursing home stay for overweight and obese participants. Conclusions: Experiencing undernutrition at the time of receipt of Medicare home health services was associated with increased health services utilization and mortality for the entire sample, and with increased health services utilization only for the overweight and obese subsample. Opportunities exist to address risk of undernutrition in patients receiving home health services, including those who are overweight or obese, to prevent subsequent adverse health outcomes. © 2011 American Medical Directors Association.

Background: Patients with head and neck cancers (HNCs) are at increased risk of experiencing malnutrition, which is associated with poor outcomes. Advances in the treatment of HNCs have resulted in improved outcomes that are associated with severe toxic oral side effects, placing patients at an even greater risk of malnutrition. Prophylactic placement of percutaneous endoscopic gastrostomy (PEG) tubes before treatment may be beneficial in patients with HNC, especially those undergoing more intense treatment regimens. PEG tube placement, however, is not without risks. Methods: A comprehensive review of the literature was conducted. Results: Systematic evidence assessing both the benefits and harm associated with prophylactic PEG tube placement in patients undergoing treatment for HNC is weak, and benefits and harm have not been established. Conclusions: More research is necessary to inform physician behavior on whether prophylactic PEG tube placement is warranted in the treatment of HNC. © 2011 American Society for Parenteral and Enteral Nutrition.

Background. Nutritional risk and low BMI are common among community-dwelling older adults, but it is unclear what associations these factors have with health services utilization and mortality over long-term follow-up. The aim of this study was to assess prospective associations of nutritional risk and BMI with all-cause, nonsurgical, and surgical hospitalization; nursing home admission; and mortality over 8.5 years. Methods. Data are from 1,000 participants in the University of Alabama at Birmingham Study of Aging, a longitudinal, observational study of older black and white residents of Alabama aged 65 and older. Nutritional risk was assessed using questions associated with the DETERMINE checklist. BMI was categorized as underweight (<18.5), normal weight (18.5-24.9), overweight (25.0-29.9), class I obese (30.0-34.9), and classes II and III obese (≥35.0). Cox proportional hazards models were fit to assess risk of all-cause, nonsurgical, and surgical hospitalization; nursing home admission; and mortality. Covariates included social support, social isolation, comorbidities, and demographic measures. Results. In adjusted models, persons with high nutritional risk had 51% greater risk of all-cause hospitalization (95% confidence interval: 1.14-2.00) and 50% greater risk of nonsurgical hospitalizations (95% confidence interval: 1.11-2.01; referent: low nutritional risk). Persons with moderate nutritional risk had 54% greater risk of death (95% confidence interval: 1.19-1.99). BMI was not associated with any outcomes in adjusted models. Conclusions. Nutritional risk was associated with all-cause hospitalizations, nonsurgical hospitalizations, and mortality. Nutritional risk may affect the disablement process that leads to health services utilization and death. These findings point to the need for more attention on nutritional assessment, interventions, and services for community-dwelling older adults. © The Author 2014.
