Background Although oncology clinical practice guidelines recognize the need and benefits of exercise, the implementation of these services into cancer care delivery remains limited. We developed and evaluated the impact of a clinically integrated 8‐week exercise and education program (CaRE@ELLICSR). Methods We conducted a mixed methods, prospective cohort study to examine the effects of the program. Each week, participants attended a 1‐h exercise class, followed by a 1.5‐h education session. Questionnaires, 6‐min walk tests (6MWT), and grip strength were completed at baseline (T0), 8 weeks (T1), and 20 weeks (T2). Semi‐structured interviews were conducted with a sub‐sample of participants about their experience with the program. Results Between September 2017 and February 2020, 277 patients enrolled in the program and 210 consented to participate in the research study. The mean …

BackgroundLimited data exist regarding the role of multimodal prehabilitation during neoadjuvant chemotherapy (NACT) for breast cancer. Determining large trial feasibility and identifying signals of prehabilitation benefit are needed.Patients and MethodsWe conducted a randomized controlled feasibility trial of multimodal prehabilitation versus usual care during NACT among women diagnosed with non-metastatic breast cancer. Intervention participants received an individualized exercise program, dietetic support, and stress management counseling during NACT. The trial assessed feasibility via rates of recruitment, attrition, adherence, and study-related adverse events. Physical fitness (Six Minute Walk Test, grip strength, anthropometrics) and patient-reported outcomes were assessed at baseline, after NACT completion, and 6 months after surgery as exploratory outcomes, and analyzed using linear mixed …

Background Allogeneic blood and marrow transplantation (alloBMT) is a curative treatment for blood cancers associated with various treatment-related adverse events and morbidities. Current rehabilitation programs are limited for patients undergoing alloBMT and research is urgently needed to test the acceptability and effectiveness of these programs. In response, we developed a 6-month multidimensional longitudinal rehabilitation program that spans from pre transplant to 3 months post transplant discharge (CaRE-4-alloBMT). Methods This study is a phase II randomized controlled trial (RCT) conducted at the Princess Margaret Cancer Centre in patients undergoing alloBMT. A total of 80 patients stratified by frailty score will be randomized to receive usual care (n = 40) or CaRE-4-alloBMT plus usual care (n = 40). The CaRE-4-alloBMT program includes individualized exercise prescriptions, access to online education through a dedicated self-management platform, wearable technology for remote monitoring, and remote tailored clinical support. Feasibility will be assessed by examining the recruitment and retention rates and adherence to the intervention. Safety events will be monitored. Acceptability of the intervention will be assessed through qualitative interviews. Secondary clinical outcomes will be collected through questionnaires and physiological assessments at baseline (T0, 2–6 weeks pre-transplant), transplant hospital admission (T1), hospital discharge (T2), and 3 months post-discharge (T3). Conclusion This pilot RCT study will determine the feasibility and acceptability of the intervention and study design and will inform full …

Background Cancer-related cognitive impairment (CRCI) is a common, persistent quality of life complaint among breast cancer survivors (BCS), however there remain no proven treatments. There is emerging evidence that aerobic exercise and yoga may improve CRCI. There remains limited research on the safety and feasibility of virtually-supervised, remotely-delivered yoga interventions among cancer survivors, and no yoga studies to date have assessed cognitive function as a primary outcome in BCS. The purpose of this study was to explore the feasibility of an 8-week, remotely-delivered yoga intervention and examine its impact on cognitive function, fatigue, and exercise levels in BCS using a concurrent mixed-methods design. Methods Participants completed objective and self-report cognitive function measures (NIH Toolbox remote cognitive battery, PsyToolkit Task Switch test, Functional Assessment of Cancer Therapy-Cognitive Function [FACT-Cog3]); fatigue (Revised-Piper Fatigue Scale); and exercise activity level (modified Godin Leisure Time Exercise Questionnaire) before and after the yoga intervention. Semi-structured qualitative interviews were conducted post-intervention to understand participants' experiences with the yoga intervention, CRCI, and fatigue. Results The intervention surpassed a priori feasibility indicators (adherence rate = 83.7%, attrition rate = 5.4%, no adverse events). Participants (n = 18, Mage= 52.2 ± 10.1) had significant improvements in objective memory, fatigue, and weekly minutes of moderate-to-vigorous exercise post-intervention. Qualitative themes indicated that participants found the remote …

Beginning in 2014, the JINS student reviewer mentorship program was initiated. The following list comprises students who conducted manuscript reviews in 2022 under the tutelage of their mentor (listed in parentheses):

Perception of bistable stimuli is influenced by prior context. In some cases, the interpretation matches with how the preceding stimulus was perceived; in others, it tends to be the opposite of the previous stimulus percept. We measured high-density electroencephalography (EEG) while participants were presented with a sequence of vowels that varied in formant transition, promoting the perception of one or two auditory streams followed by an ambiguous bistable sequence. For the bistable sequence, participants were more likely to report hearing the opposite percept of the one heard immediately before. This auditory contrast effect coincided with changes in alpha power localized in the left angular gyrus and left sensorimotor and right sensorimotor/supramarginal areas. The latter correlated with participants' perception. These results suggest that the contrast effect for a bistable sequence of vowels may be related to …

IntroductionPeople treated with systemic therapies for cancer may exhibit changes in neurocognitive functioning over time, affecting domains such as memory, processing speed, and executive functioning. There is a need for prospective data regarding neurocognitive outcomes among patients treated with Chimeric Antigen Receptor T-Cell (CAR T) therapy. The purpose of this study was to investigate the trajectory of neurocognitive performance and self-reported cognitive functioning over the first 3 months of CAR T therapy.MethodsAs part of a larger cohort study of patients treated with CAR T, neurocognitive outcomes were assessed prior to starting CAR T and again at 1- and 3- months post-CAR T. Neurocognitive performance was measured using standardized neuropsychological tests including measures of verbal memory (Hopkins Verbal Learning Test-Revised (HVLT-R) - immediate recall, delayed recall …

Background In addition to poor survival rates, individuals with glioblastoma (GBM) are at risk of neurocognitive impairment due to multiple factors. This study aimed to characterize neurocognitive impairment, neurobehavioral symptoms, fatigue, sleep disturbance, and depressive symptoms in newly diagnosed GBM patients; and to examine whether neurobehavioral symptoms, fatigue, sleep, and depressive symptoms influence neurocognitive performance. Methods This study was part of a prospective, inception cohort, single-arm exercise intervention in which GBM patients underwent a neuropsychological assessment shortly after diagnosis (median 4 weeks; ie, baseline) and 3, 6, 12, and 18 months later, or until tumor progression. Here, we present baseline data. Forty-five GBM patients (mean age = 55 years) completed objective neurocognitive tests, and self-report measures …

Background:Meta-analyses have demonstrated that brief interventions can address fear of cancer recurrence (FCR), but their mechanisms of action are largely unknown. Our goal was to identify the mediators of treatment efficacy of the Fear Of Recurrence Therapy (FORT) intervention using data from a multisite randomized controlled trial targeting FCR. That randomized controlled trial compared a 6-week cognitive-existential group intervention with an active control group.Methods:Participants (n= 135) were women diagnosed with stage I-III breast or gynecological cancer who were assessed at 4 time points (pretherapy, post-therapy, 3-month, and 6-month follow-up). The primary outcome, changes in FCR at 6 months, was measured with the Fear of Cancer Recurrence Inventory. We examined 6 mediators based on our theoretical model of FCR: perceived risk of recurrence, uncertainty in illness, intolerance of …

Background: Some levothyroxine (LT4)-treated hypothyroid patients report a constellation of persistent and distressing cognitive symptoms that has been termed brain fog. This narrative review focuses on attempts to define and measure hypothyroid-associated brain fog, summarize possible etiologies and contributing factors, present treatment options, and propose avenues for future research. Methods: Published literature was reviewed to summarize available information on patient-reported symptoms associated with brain fog in hypothyroidism, as well as objective evidence of impairment based on neurocognitive testing and functional imaging studies. Given the limited information specific for hypothyroid-associated brain fog, relevant data from other medical conditions associated with brain fog were also reviewed and incorporated into recommendations for clinical care and future research areas. Results …

Cancer patients and survivors frequently experience cognitive deficits, including problems with attention and memory. These symptoms, referred to as cancer-related cognitive dysfunction (CRCD), are associated with distress. Learning about CRCD and self-management strategies may improve functioning and quality of life in cancer survivors. This study describes the development and evaluation of a CRCD resource for cancer patients. An educational booklet was developed in accordance with multiple evidence-based guidelines for cancer patient education. Cancer patients on chemotherapy (N = 113; 34% men; median age 55, range 19–85) reviewed the booklet and self-reported CRCD knowledge before and after reading the booklet. They also gave ratings on general impressions of the booklet. Seventy-five percent of participants reported that the resource increased their self-reported CRCD knowledge. A …

IntroductionEosinophilic Esophagitis (EoE) is a chronic immune mediated disorder involving eosinophils leading to esophageal dysfunction. In this retrospective multi-center study, we investigated the incidence and risk factors for comorbid autoimmune diseases (AiD) in children using Cerner Health Facts, a national longitudinal database representing approximately 69 million patients.MethodsAll patients under 18 years of age with EoE were included in our analysis. Patient characteristics were evaluated as potential risk factors for comorbid AiD using multivariable regression built using all variables with p<0.05 on univariable analysis.ResultsWe identified 6,285 patients with EoE. Mean age was 9.41±5.04 years, 32.04% (2,014) were female. In terms of race, 75.27% (4,731) were white and 11.81% (742) were African American. Overall, 7.0% (440/6,285) of children with EoE had at least one comorbid AiD. The most …

The perception of concurrent sound sources depends on processes (i.e., auditory scene analysis) that fuse and segregate acoustic features according to harmonic relations, temporal coherence, and binaural cues (encompass dichotic pitch, location difference, simulated echo). The object-related negativity (ORN) and P400 are electrophysiological indices of concurrent sound perception. Here, we review the different paradigms used to study concurrent sound perception and the brain responses obtained from these paradigms. Recommendations regarding the design and recording parameters of the ORN and P400 are made, and their clinical applications in assessing central auditory processing ability in different populations are discussed.

PurposeThe contributory effects of radiation dose to different brain regions on neurocognitive performance after radiation therapy (RT) for primary brain tumors is not well known.Methods and MaterialsIn this retrospective cohort study, 30 patients with brain tumors treated with photon RT were identified, and radiation dosimetric parameters across brain regions were calculated. All patients had longitudinal neurocognitive evaluations at baseline and after treatment. Generalized estimating equations were used to model each neurocognitive endpoint over time in a multivariable analysis, while adjusted for multiple comparisons of brain regions.ResultsMedian follow-up from RT to last assessment was 4.1 years. Fewer years of formal education and older age at the time of RT were associated with lower scores in language, verbal memory, and working memory, after adjustment for baseline scores in multivariable …

Prompt services and work-focused support systems are needed to aid cancer survivors returning to work or finding work. Purpose This knowledge translation and implementation project focused on the knowledge users' experience and need for refinement of three work-focused tools to support return to work and maintain work following cancer through their participation in a hands-on workshop. The tools assessed for their utility are a Job Analysis Tool (JAT), a Return to Work (RTW) tool, and a bilingual Canadian website on Cancer and Work. Methods Four workshops took place in three Canadian cities. Participants included cancer survivors, healthcare professionals, and employer representatives. Following an overview of the website and tools, workshop participants (N = 28) completed qualitative and quantitative satisfaction and usability questionnaires using the System Usability Scale and open-ended …

Adults with non-central nervous system (CNS) cancers frequently report problems in attention, memory and executive function during or after chemotherapy, referred to as cancer-related cognitive dysfunction (CRCD). Despite numerous studies investigating CRCD, there is no consensus regarding the brain areas implicated. We sought to determine if there are brain areas that consistently show either hyper- or hypo-activation in people treated with chemotherapy for non-CNS cancer (Chemo+). Using activation likelihood estimation on brain coordinates from 14 fMRI studies yielding 25 contrasts from 375 Chemo+ and 429 chemotherapy-naive controls while they performed cognitive tasks, the meta-analysis yielded two significant clusters which are part of the frontoparietal attention network, both showing lower activation in Chemo+. One cluster peaked in the left superior parietal cortex, extending into precuneus …

ObjectivesSexual health problems have been identified as an unmet need in head and neck cancer (HNC) survivors. In particular, little is known about such outcomes in survivors of nasopharyngeal cancer (NPC).Materials and methodsA cross-sectional study of NPC survivors with ≥4y follow-up was undertaken. Sexual satisfaction was assessed using the optional “I am satisfied with my sex life” item of the FACT-H&N. Other patient-reported outcomes measures were also captured including fatigue (FACIT-F), HNC symptom burden (MDASI-HN), emotional distress (HADS) and frontal function (FrSBE). Univariate and multivariate analyses were performed to determine factors influencing sexual satisfaction.ResultsThe sexual satisfaction item was answered by 85/103 (83%) enrollees. Female (p < 0.001) and non-partnered (p = 0.0045) patients were more likely to abstain from answering. The distribution of …

Background Although facility-based cancer rehabilitation and exercise programs exist, patients are often unable to attend due to distance, cost, and other competing obligations. There is a need for scalable remote interventions that can reach and serve a larger population. Methods We conducted a mixed methods pilot study to assess the feasibility, acceptability and impact of CaRE@Home: an 8-week online multidimensional cancer rehabilitation and exercise program. Feasibility and acceptability data were captured by attendance and adherence metrics and through qualitative interviews. Preliminary estimates of the effects of CaRE@Home on patient-reported and physically measured outcomes were calculated. Results A total of n = 35 participated in the study. Recruitment (64%), retention (83%), and adherence (80%) rates, along with qualitative findings, support the feasibility of the CaRE@Home intervention. Acceptability was also high, and participants provided useful feedback for program improvements. Disability (WHODAS 2.0) scores significantly decreased from baseline (T1) to immediately post-intervention (T2) and three months post-intervention (T3) (p = 0.03 and p = 0.008). Physical activity (GSLTPAQ) levels significantly increased for both Total LSI (p = 0.007 and p = 0.0002) and moderate to strenuous LSI (p = 0.003 and p = 0.002) from baseline to T2 and T3. Work productivity (iPCQ) increased from T1 to T3 (p = 0.026). There was a significant increase in six minute walk distance from baseline to T2 and T3 (p < 0.001 and p = 0.010) and in grip strength from baseline to T2 and T3 (p = 0.003 and p < 0.001).
