RESUMO

Importance: Cognitive dysfunction is common after traumatic brain injury (TBI), with a well-established dose-response relationship between TBI severity and likelihood or magnitude of persistent cognitive impairment. However, patterns of cognitive dysfunction in the long-term (eg, 6-month) recovery period are less well known. Objective: To characterize the prevalence of cognitive dysfunction within and across cognitive domains (processing speed, memory, and executive functioning) 6 months after injury in patients with TBI seen at level I trauma centers. Design, Setting, and Participants: This prospective longitudinal cohort study used data from Transforming Research and Clinical Knowledge in TBI (TRACK-TBI) and included patients aged 17 years or older presenting at 18 US level I trauma center emergency departments or inpatient units within 24 hours of head injury, control individuals with orthopedic injury recruited from the same centers, and uninjured friend and family controls. Participants were enrolled between March 2, 2014, and July 27, 2018. Data were analyzed from March 5, 2020, through October 3, 2023. Exposures: Traumatic brain injury (Glasgow Coma Scale score of 3-15) or orthopedic injury. Main Outcomes and Measures: Performance on standard neuropsychological tests, including premorbid cognitive ability (National Institutes of Health Toolbox Picture Vocabulary Test), verbal memory (Rey Auditory Verbal Learning Test), processing speed (Wechsler Adult Intelligence Scale [4th edition] Processing Speed Index), and executive functioning (Trail Making Test). Results: The sample included 1057 persons with TBI (mean [SD] age, 39.3 [16.4] years; 705 [67%] male) and 327 controls without TBI (mean [SD] age, 38.4 [15.1] years; 222 [68%] male). Most persons with TBI demonstrated performance within 1.5 SDs or better of the control group (49.3% [95% CI, 39.5%-59.2%] to 67.5% [95% CI, 63.7%-71.2%] showed no evidence of impairment). Similarly, 64.4% (95% CI, 54.5%-73.4%) to 78.8% (95% CI, 75.4%-81.9%) of participants demonstrated no evidence of cognitive decline (defined as performance within 1.5 SDs of estimated premorbid ability). For individuals with evidence of either cognitive impairment or decline, diverse profiles of impairment across memory, speed, and executive functioning domains were observed (ie, the prevalence was >0 in each of the 7 combinations of impairment across these 3 cognitive domains for most TBI subgroups). Conclusions and Relevance: In this cohort study of patients seen at level I trauma centers 6 months after TBI, many patients with TBI demonstrated no cognitive impairment. Impairment was more prevalent in persons with more severe TBI and manifested in variable ways across individuals. The findings may guide future research and treatment recommendations.

RESUMO

OBJECTIVE: To determine the feasibility and acceptability of an mHealth, home-based exercise intervention among stage II-III colorectal cancer (CRC) survivors within 5-years post-resection and adjuvant therapy. METHODS: This pilot randomized controlled trial of a 12-week mHealth, home-based exercise intervention, randomly assigned CRC survivors to a high-intensity interval training (HIIT) or moderate-intensity continuous exercise (MICE) prescription. The following assessments were carried out at baseline and end-of-study (EOS): handgrip strength, short physical performance battery (SPPB), PROMIS physical function, neuropathy total symptom score-6 (NTSS-6), Utah early neuropathy scale (UENS), cardiopulmonary exercise testing, anthropometrics, and body composition via BOD POD, modified Godin leisure-time activity questionnaire. Feasibility, as defined by number of completed prescribed workouts and rate of adherence to individualized heart rate (HR) training zones, was evaluated at EOS. Acceptability was assessed by open-ended surveys at EOS. Descriptive statistics were generated for participant characteristics and assessment data. RESULTS: Seven participants were included in this pilot study (MICE: n = 5, HIIT: n = 2). Median age was 39 years (1st quartile: 36, 3rd quartile: 50). BMI was 27.4 kg/m2 (1st quartile: 24.5, 3rd quartile: 29.7). Most participants had stage III CRC (71%, n = 5). We observed an 88.6% workout completion rate, 100% retention rate, no adverse events, and qualitative data indicating improved quality of life and positive feedback related to ease of use, accountability, motivation, and autonomy. Mean adherence to HR training zones was 95.7% in MICE, and 28.9% for the high-intensity intervals and 51.0% for the active recovery intervals in HIIT; qualitative results revealed that participants wanted to do more/work-out harder. CONCLUSION: An mHealth, home-based delivered exercise intervention, including a HIIT prescription, among stage II-III CRC survivors' post-resection and adjuvant therapy was tolerable and showed trends towards acceptability.

RESUMO

PURPOSE: To assess the impact of the Personal Optimism With Exercise Recovery (POWER) program on cancer treatment-related side effects among rural cancer survivors. METHODS: In this retrospective study of data collected between 2016 and 2019, we assessed change in cardiorespiratory fitness, whole-body muscular endurance, physical function and strength, anthropometrics, fatigue, and quality of life (QoL), after participation in POWER. Descriptive statistics were calculated for demographic and clinical variables. Univariate analysis of variance was carried out with age and BMI at initial assessment as covariates. RESULTS: A total of 239 survivors, 78% rural residents, completed a follow-up assessment. Among rural cancer survivors, the most prevalent cancer sites were breast (42.5%), prostate (12.4%), and lymphoma (5.9%). The majority of survivors were female (70%), non-Hispanic (94.6%), and white (93.5%), with average age and BMI of 62.1 ± 13.2 years and 28.4 ± 6.7 kg/m2, respectively. Rural cancer survivors with cancer stages I-III exhibited significant improvements in fitness (+ 3.07 ml/kg/min, 95% CI 1.93, 4.21; + 0.88 METS, 95% CI 0.55, 1.20), physical function (30-s chair stand: + 2.2 repetitions, 95% CI 1.3, 3.1), muscular endurance (10-repetition maximum: chest press + 4.1 kg, 95% CI 2.0, 6.3; lateral pulldown + 6.6 kg, 95% CI 4.4, 8.9), self-reported fatigue (FACIT-Fatigue score: + 4.9, 95% CI 1.6, 8.1), and QoL (FACT-G7 score + 2.1, 95% CI, 0.9, 3.4). Among stage IV rural and urban cancer survivors, significant improvements were observed in muscular endurance and physical function. CONCLUSION: Participation in POWER was associated with attenuation of cancer treatment-related side effects and may serve as a model exercise oncology program for rural cancer survivors.
