RESUMEN
INTRODUCTION: Advance care planning (ACP) has been widely endorsed and recommended for its many potential benefits, including improved end-of-life (EOL) care, enhanced satisfaction with care, and reduced anxiety and depression. However, little is known about the ACP completion rates and factors affecting ACP among older adults with cancer. This study's purpose was to examine biological, psychological, and social factors affecting ACP in this population. MATERIALS AND METHODS: Data from the 2002 to 2016 waves of exit interviews from the national longitudinal Health and Retirement Study were analyzed. The sample included 1088 decedents, aged 55 and over, who had a diagnosis of cancer. The exit interviews were completed by a proxy respondent (usually the next of kin of the decedents). ACP outcomes included: having EOL care discussion, durable power of attorney (DPOA), and advance directives (ADs). Multiple logistic regression models were conducted to examine the relationships between predictor variables and each of the three ACP outcome variables. RESULTS: Approximately 65% of the sample had ever discussed EOL care, 61.9% had an assigned DPOA, and 54.1% had ADs. Regression results showed that higher age, Black race, high school and above education, being widowed/never married, higher multimorbidity, and more limitations in activities of daily living and instrumental activities of daily living were significantly associated with the three ACP variables. Surprisingly, Black race was associated with higher odds of ever discussing EOL care and having ADs; high school and above education was associated with lower odds of all three ACP components. DISCUSSION: The majority of participants in this study had discussed EOL care, had an assigned DPOA, and had ADs. However, most participants were White/Caucasian and had completed high school education. Future research that includes more diverse and minoritized participants is needed. Also, the contrasting association of Black race and higher educational status with ACP outcomes warrant further exploration in future studies.
RESUMEN
OBJECTIVES: To gather feasibility and preliminary data comparing two virtual delivery methods for providing Emerging From the Haze™ (Haze) to cancer survivors compared to waitlist control (WLC). SAMPLE & SETTING: Eligible participants (N = 93) reported cancer-related cognitive impairment following chemotherapy for stage I-III solid tumors, Hodgkin lymphoma, or non-Hodgkin lymphoma. METHODS & VARIABLES: A three-arm randomized design was used to compare virtual live group presentation of Haze sessions, virtual prerecorded Haze group sessions, and WLC. Data were collected at baseline, week 10, and week 14. RESULTS: Feasibility was demonstrated. Significant cognitive function improvement at week 10 versus WLC was reported for the live group, and clinical improvement was reported for the prerecorded group. The prerecorded group reported significant improvement at week 14 versus WLC in physical activity, sleep, and health-related quality of life. IMPLICATIONS FOR NURSING: Additional pilot and feasibility evidence for cognitive rehabilitation interventions was demonstrated. Prerecorded Haze delivery shows potential for clinical effectiveness and scalability. Future multisite research is warranted.

PURPOSE: Oncology advanced practice providers (APPs), including nurse practitioners, clinical nurse specialists, physician assistants, and clinical pharmacists, contribute significantly to quality cancer care. Understanding the research-related roles of APPs in the National Cancer Institute's (NCI) Community Oncology Research Program (NCORP) could lead to enhanced protocol development, trial conduct, and accrual. METHODS: The 2022 NCORP Landscape Assessment Survey asked two questions about the utilization and roles of APPs in the NCORP. RESULTS: A total of 271 practice groups completed the 2022 survey, with a response rate of 90%. Of the 259 nonpediatric exclusive practice groups analyzed in this study, 92% used APPs for clinical care activities and 73% used APPs for research activities. APPs most often provided clinical care for patients enrolled in trials (97%), followed by assistance with coordination (65%), presenting/explaining clinical trials (59%), screening patients (49%), ordering investigational drugs (37%), and consenting participants (24%). Some groups reported APPs as an enrolling investigator (18%) and/or participating in institutional oversight/selection of trials (15%). Only 5% of NCORP sites reported APPs as a site primary investigator for trials, and very few (3%) reported APPs participating in protocol development. CONCLUSION: Practice groups report involving APPs in clinical research within the NCORP network; however, opportunities for growth exists. As team-based care has enhanced clinical practice in oncology, this same approach can be used to enhance successful research. Suggested strategies include supporting APP research-related time, recognition, and education. The findings of this survey and subsequent recommendations may be applied to all adult oncology practices that participate in clinical research.

BACKGROUND: Androgen deprivation therapy (ADT) for prostate cancer is associated with cardiovascular comorbidities and numerous adverse effects decreasing health-related quality of life. Both exercise and dietary interventions have shown promise in reducing ADT-related negative sequelae. However, feasibility for personalized combined exercise/nutrition/education interventions is not well established. OBJECTIVE: The purpose of this randomized, controlled, mixed-methods pilot study was to evaluate the feasibility of a nurse-led, telephone-delivered education, exercise, and nutrition intervention, Staying Strong & Healthy, to minimize ADT-related cardiovascular/metabolic risks and symptoms. METHODS: Staying Strong & Healthy involves individually tailored education, exercise (aerobic and resistance), and nutrition intervention delivered over 6 months and was compared with attention control. The primary quantitative outcome measure was change from baseline in low-density lipoprotein. Secondary outcomes included change in lipid levels (total cholesterol, high-density lipoprotein, low-density lipoprotein, and triglycerides), fasting blood glucose, hemoglobin A 1c , health-related quality of life, and diet quality. Assessments were performed at baseline, 6 months, and 12 months. RESULTS: Feasibility was demonstrated by low attrition rates and high participant satisfaction. No between-group differences were demonstrated in the cardiovascular/metabolic outcomes. Significant within-group improvements were noted for high-density lipoprotein and hemoglobin A 1c in the intervention group. CONCLUSION: The study results indicate that participation in a personalized, nurse-delivered exercise, nutrition, and educational intervention is feasible and acceptable to men with prostate cancer receiving ADT. IMPLICATIONS FOR PRACTICE: Future randomized controlled research powered to detect significant differences is needed to confirm the impact of the Staying Strong & Healthy intervention on reduction of the cardiovascular/metabolic impact of ADT for men with prostate cancer.

Introduction: Patients receiving cancer treatment are at high risk for falls. No current guidelines or standards of care exist for assessment and prevention of outpatient oncology falls. This quality improvement project's purpose was to 1) describe and evaluate outpatient oncology falls data to determine root cause(s), and develop, implement, and evaluate intervention strategies for future policy refinement, and 2) compare fall rates pre/post implementation of a system-wide Ambulatory Fall Risk Bundle. Methods: Retrospective data were used to describe and categorize fall incidence for the University of Kansas Cancer Center over 12 months. Further analyses were conducted to describe fall rates per 10,000 kept appointments pre/post implementation of an Ambulatory Fall Risk Bundle protocol. Semi-structured interviews were conducted with medical assistants and nurse managers to evaluate the initiative's impact, staff satisfaction, and recommendations for refinement. Results: The initial 12-month assessment yielded 58 patient falls retained for further analyses. Most patients were receiving chemotherapy (46, 79%). Common contributing symptoms included dizziness/ faintness and weakness (25, 43%). Tripping/falling over a hazard (12, 24%) and falls during transfer (10, 5.8%) also were cited. Subsequent analyses of fall rates indicated no change. Recommendations resulting from the qualitative interviews included: orthostatic vital sign protocol implementation, redesign of the electronic medical record fall risk alert, stakeholder involvement in protocol development, staff training, and related patient education strategies, and the procurement of additional assistive devices/equipment. Conclusions: System-related policy and culture change, investment in physical and human resource enhancements, and evidence-based protocols are needed to improve outpatient oncology fall rates.
RESUMEN
BACKGROUND: Patients prefer medical communication including both hopefulness and realism, though health-care professional (HCPs) struggle to balance these. Providers could thus benefit from a detailed personal understanding of hope, allowing them to model and convey it to patients. Additionally, given that hope is associated with lower levels of burnout, HCPs may benefit from tools designed to enhance their own personal hopefulness. Several investigators have proposed offering HCPs interventions to augment hope. We developed an online workshop for this purpose. METHODS: Feasibility and acceptability of the workshop were assessed in members of the SWOG Cancer Research Network. Three measures were used: the Was-It-Worth-It scale, a survey based on the Kirkpatrick Training Evaluation Model, and a single item prompting participants to rate the degree to which they believe concepts from the workshop should be integrated into SWOG studies. RESULTS: Twenty-nine individuals signed up for the intervention, which consisted of a single 2-hour session, and 23 completed measures. Results from Was-It-Worth-It items indicate that nearly all participants found the intervention relevant, engaging, and helpful. Mean ratings for Kirkpatrick Training Evaluation Model items were high, ranging from 6.91 to 7.70 on 8-point scales. Finally, participants provided a mean rating of 4.44 on a 5-point scale to the item "To what degree do you believe it may be useful to integrate concepts from this workshop into SWOG trials/studies?" CONCLUSIONS: An online workshop to enhance hopefulness is feasible and acceptable to oncology HCPs. The tool will be integrated into SWOG studies evaluating provider and patient well-being.

Approximately 40% of patients with cancer are eligible for check-point inhibitor (CPI) therapy. Little research has examined the potential cognitive impact of CPIs. First-line CPI therapy offers a unique research opportunity without chemotherapy-related confounders. The purpose of this prospective, observational pilot was to (1) demonstrate the feasibility of prospective recruitment, retention, and neurocognitive assessment for older adults receiving first-line CPI(s) and (2) provide preliminary evidence of changes in cognitive function associated with CPI(s). Patients receiving first-line CPI(s) (CPI Group) were assessed at baseline (n = 20) and 6 months (n = 13) for self-report of cognitive function and neurocognitive test performance. Results were compared to age-matched controls without cognitive impairment assessed annually by the Alzheimer's Disease Research Center (ADRC). Plasma biomarkers were measured at baseline and 6 months for the CPI Group. Estimated differences for CPI Group scores prior to initiating CPIs (baseline) trended to lower performance on the Montreal Cognitive Assessment-Blind (MOCA-Blind) test compared to the ADRC controls (p = 0.066). Controlling for age, the CPI Group's 6-months MOCA-Blind performance was lower than the ADRC control group's 12-months performance (p = 0.011). No significant differences in biomarkers were detected between baseline and 6 months, although significant correlations were noted for biomarker change and cognitive performance at 6 months. IFNγ, IL-1ß, IL-2, FGF2, and VEGF were inversely associated with Craft Story Recall performance (p < 0.05), e.g., higher levels correlated with poorer memory performance. Higher IGF-1 and VEGF correlated with better letter-number sequencing and digit-span backwards performance, respectively. Unexpected inverse correlation was noted between IL-1α and Oral Trail-Making Test B completion time. CPI(s) may have a negative impact on some neurocognitive domains and warrant further investigation. A multi-site study design may be crucial to fully powering prospective investigation of the cognitive impact of CPIs. Establishment of a multi-site observational registry from collaborating cancer centers and ADRCs is recommended.
RESUMEN
PURPOSE: The purpose of this study was to investigate the association between loneliness and cancer-related cognitive impairment (CRCI) in a cohort of breast cancer survivors. METHODS: Female breast cancer survivors (stage I-III) reporting cognitive impairments 2 months to 5 years after chemotherapy (n = 61) participated in a prospective, nonblinded, waitlist-controlled pilot study. The intervention was a tailored cognitive rehabilitation program. Data were collected pre-/post-intervention. Loneliness was measured using the UCLA Loneliness Scale. Perceived cognitive function was measured using two subscales of the FACT-Cog and two PROMIS - Applied Cognition short forms. Spearman correlation coefficients were calculated to determine the relationship between loneliness and perceived cognitive function (PCF). RESULTS: Participants' loneliness severity was correlated with diminished PCF across all cognitive measures (Spearman r= -0.63 FACT-Cog Perceived Cognitive Impairment, p < 0.0001; r= -0.6 FACT-Cog Perceived Cognitive Abilities, p < 0.0001; r= -0.49 PROMIS Cognitive Ability, p = 0.0002; r = 0.50 PROMIS General Concerns, p = 0.0002). Loneliness scores significantly decreased following participation in the cognitive rehabilitation program in intervention participants as compared to wait-list controls [-5.0 ± 7.24, 95% CI (-8.06, -1.94), p = 0.0025]. CONCLUSIONS: Perceived loneliness was significantly and consistently correlated with PCF. The intervention may have served a dual purpose in both addressing cognitive deficits and loneliness. Additional research dedicated to understanding the association between loneliness and cognitive function, as well as screening for and addressing loneliness in clinical oncology settings, may be warranted. IMPLICATIONS FOR REHABILITATIONScreening for and addressing loneliness in oncology rehabilitation settings is warranted.Rehabilitation professionals are well-positioned to screen for and address loneliness during clinic visits as part of routine cancer rehabilitation care.Group settings may be appropriate for addressing cancer-related cognitive impairment in rehabilitation, as these groups may serve the dual purpose of addressing cognitive impairment and loneliness simultaneously.

BACKGROUND: Men receiving androgen deprivation therapy (ADT) for prostate cancer (PC) are at risk for cardiovascular comorbidities and cognitive changes. Interventional research involves in-person assessment of physical fitness/activity and cognitive function, which has been negatively affected by the COVID-19 pandemic. Androgen deprivation therapy-related hot flashes and nocturia increase risk for insomnia. Insomnia is associated with fatigue and may exacerbate ADT-related cognitive changes. OBJECTIVES: The purpose of this mixed-methods pilot was to (1) determine feasibility/acceptability of remotely assessing physical fitness/activity, cognitive function, and sleep; (2) deliver telehealth cognitive behavioral training for insomnia (teleCBT-I) to improve sleep; and (3) garner qualitative feedback to refine remote procedures and teleCBT-I content. METHODS: Fifteen men with PC receiving ADT completed a 4-week teleCBT-I intervention. Videoconferencing was used to complete study assessments and deliver the weekly teleCBT-I intervention. RESULTS: Self-report of sleep quality improved ( P < .001) as did hot flash frequency ( P = .04) and bother ( P = .025). Minimal clinically important differences were detected for changes in insomnia severity and sleep quality. All sleep logs indicated improvement in sleep efficiency. Remote assessment of fitness/cognitive function was demonstrated for 100% of participants. Sufficient actigraph wear time allowed physical activity/sleep assessment for 80%. Sleep actigraphy did not demonstrate significant changes. CONCLUSIONS: Remote monitoring and teleCBT-I are feasible/acceptable to men with PC on ADT. Further research to confirm teleCBT-I efficacy is warranted in this population. IMPLICATIONS FOR PRACTICE: Preliminary efficacy for teleCBT-I interventions was demonstrated. Remote assessments of physical fitness/activity, sleep, and cognitive function may enhance clinical trial access for rural or economically disadvantaged PC survivors.

BACKGROUND: Interventions that increase neuroprotective factors and/or decrease inflammatory biomarkers may be effective in improving cognitive function for cancer survivors. Concurrent investigation of potential mechanism(s) to fully understand and refine effective interventions is needed. OBJECTIVE: This correlative prospective substudy was conducted to investigate biomarkers related to potential mechanism(s) for a combined exercise and game-based brain training intervention designed to improve cognitive function in breast cancer survivors. INTERVENTIONS/METHODS: Fingerstick bloodspot samples were collected at 3 time points during the randomized, wait-list controlled interventional parent study. Samples were analyzed for neuroprotective factors and inflammatory biomarker levels. RESULTS: Insulinlike growth factor 1 (IGF-1) levels significantly increased (P < .01) for the intervention group from baseline to 4 and 16 weeks postintervention. Insulinlike growth factor 1 levels correlated with neurocognitive test performace improvement for Trail Making Test B (r = 0.31, P = .02). This association was not significant in the mixed model. No significant correlation was seen between IGF-1 levels and changes in self-report of cognitive function, activity level, or intervention dose. CONCLUSIONS: Further investigation of IGF-1 levels is warranted as related to potential mechanisms for the Combined Exercise and Game-based Cognitive Training intervention. Future investigations should involve a larger sample cohort and incorporate objective measures of physical activity and prescribed sampling time in relationship to the most recent performance of the intervention. IMPLICATIONS FOR PRACTICE: Fingerstick bloodspot sample collection is feasible, acceptable, and effective for conducting biomarker research. This methodology minimizes participant burden and discomfort; increases clinical trial access for home, off-site, or rural settings; and facilitates research efforts during times of pandemic restrictions.
RESUMEN
Aim: Stakeholder engagement is central to comparative effectiveness research yet there are gaps in definitions of success. We used a framework developed by Lavallee et al. defining effective engagement criteria to evaluate stakeholder engagement during a pragmatic cluster-randomized trial. Methods: Semi-structured interviews were developed from the framework and completed to learn about members' experiences. Interviews were analyzed in a deductive approach for themes related to the effective engagement criteria. Results: Thirteen members participated and described: respect for ideas, time to achieve consensus, access to information and continuous feedback as areas of effective engagement. The primary criticism was lack of diversity. Discussion: Feedback was positive, particularly among themes of respect, trust and competence, and led to development of a list of best practices for engagement. The framework was successful for evaluating engagement. Conclusion: Standardized frameworks allow studies to formally evaluate their stakeholder engagement approach and develop best practices for future research.
What is this article about? This article is about the evaluation of how effective the stakeholder engagement was in a comparative effectiveness research (CER) study funded by the Patient Centered Outcomes Research Institute (PCORI). The research team found a framework (developed by Lavalle et al.) that defined six different criteria for effective stakeholder engagement, and used that criteria to complete semi-structured interviews with the stakeholders involved with our study. These interviews were reviewed to determine what stakeholder engagement processes were successful and helped provide a list of best practices for stakeholder engagement for other researchers doing CER. What were the results? Stakeholders highlighted respect for their ideas, time to achieve consensus, easy access to information and a continuous feedback loop between study team and stakeholders as effective engagement processes. What do the results mean? These results can help other researchers doing CER learn best practices to implement from the outset of a study to best engage stakeholders in their research. The results also show that having a standardized framework to evaluate stakeholder engagement is important and allows for research teams to formally evaluate their engagement approach and learn what was successful and where there are areas for improvement in future studies.

INTRODUCTION: Type 2 diabetes mellitus (T2DM) is a prevalent metabolic disorder characterized by hyperglycemia of varying degrees. Genetic and lifestyle variations are known to influence the onset and severity of T2DM. Among the genetic variations reported to confer susceptibility to the disease are certain single nucleotide polymorphisms (SNPs). Here, we report the analysis of 18 such SNPs in a military community cohort of 716 subjects, comprising 477 diabetic and 239 control subjects. The population studied included active-duty military personnel, veterans, and their families. The SNPs analyzed in this work occur in nine different genes, comprising six interleukin (IL) genes (IL1A, IL1B, IL4, IL6, IL10, and IL18), fatty acid amide hydrolase (FAAH) gene, and cannabinoid receptors 1 and 2 genes (CNR1, CNR2). The products of these genes are players in different conditions, including inflammation, a process linked with diabetes. MATERIALS AND METHODS: The T2DM and control (no diabetes) DNA samples were acquired from an archived sample repository (Center for Advanced Molecular Detection, 59th Medical Wing, U.S. Air Force, Joint Base San Antonio [JBSA]-Lackland, TX). The blood samples had been previously collected from gender- and race-mixed cohorts under a protocol approved by the 59th Medical Wing Institutional Review Board. Single nucleotide polymorphism (SNP) genotyping was done by real-time Polymerase Chain Reaction (PCR) using TaqMan assay reagents. The statistical analysis software 9.3 (SAS 9.3) was used for statistical analyses to reveal associations between the SNP genotypes and T2DM. RESULTS: Out of the 18 SNPs analyzed, six showed statistically significant association with T2DM in the overall cohort (P < .05). The odds ratio for these associations varied from 1.57 to 3.16. The rs16944 T/T homozygous genotype (IL1B) showed the strongest association with T2DM, with P = .005. In the White cohort, five of these six SNPs and one other, rs806368 (cannabinoid receptor 1), associate with T2DM. However, the gender-specific analysis of the White cohort revealed only two SNP associations with T2DM in the female cohort, rs16944 (IL1B) and rs2295632 (FAAH), both also showing association in the overall mixed cohort. Likewise, four SNPs showed T2DM association in the White male cohort, with rs187238 (IL18) being uniquely significant in this group. CONCLUSIONS: The IL1B SNP rs16944 showed consistent statistically significant association with T2DM and therefore is likely a promising biomarker for T2DM. We note, however, that this association in a generic sense may be with the inflammatory process that accompanies T2DM and not per se with T2DM.
RESUMEN
OBJECTIVES: To gather preliminary data on correlations among psycholinguistic measures, self-report of cognitive function, and performance on neurocognitive tests in breast cancer survivors. SAMPLE & SETTING: Participants were breast cancer survivors who reported issues with cognitive function after completion of chemotherapy. This secondary analysis used data from participants in parent studies at two National Cancer Institute-designated cancer centers. METHODS & VARIABLES: Qualitative interview transcripts (N = 52) underwent psycholinguistic analyses for grammatical and semantic complexity. Relationships among six psycholinguistic variables, self-report of cognitive function, and performance on neurocognitive tests were examined. RESULTS: Three grammatical complexity variables had a significant positive correlation to self-report of cognitive function. One semantic complexity variable had a significant positive correlation to delayed recall neurocognitive tests. IMPLICATIONS FOR NURSING: Results suggest that psycholinguistic analysis may be used to assess cognitive function among breast cancer survivors. Confirmatory studies are needed to establish the correlation between psycholinguistic measures, self-report of cognitive function, and domain-specific tests of neurocognitive performance, as well as to evaluate longitudinal sensitivity to change.

Objective: Cancer-related cognitive impairments experienced by cancer survivors cause many to seek non-pharmacological intereventions to manage these symptoms. The aim of this systematic review was to evaluate the effects of one such intervention, mindbody exercise (MBE), on cognitive function in cancer survivors. Design: Searches for relevant studies were conducted in four electronic databases, including PubMed, Embase, Scopus, and Web of Science. The Joanna Briggs Institute and Jadad scales were utilized to evaluate the quality of the selected studies. Results: Eleven studies including 1,032 participants, published between 2006 and 2019, were selected for review based on specific inclusion criteria. Our results indicated that interventions including, yoga, tai chi, and qigong may improve objective and subjective cognitive function in cancer survivors. Conclusion: Cancer survivors experiencing cognitive symptoms may benefit from participation in MBE. Adequately powered randomized controlled trials are required to establish the short- and long-term effects of MBE on cognitive functioning.
RESUMEN
BACKGROUND: Administration of four to six consecutive monthly doses of 24 µg/kg moxidectin alone shows high effectiveness in preventing the maturation of macrocyclic lactone (ML)-resistant heartworm strains, Dirofilaria immitis JYD-34 and ZoeLA. This laboratory study evaluated the efficacy of six consecutive monthly oral doses of Simparica Trio® (moxidectin/sarolaner/pyrantel) compared to six monthly doses of either Heartgard® Plus (ivermectin/pyrantel) or Interceptor® Plus (milbemycin oxime/praziquantel) against ML-resistant D. immitis ZoeLA strain. METHODS: Beagle dogs were inoculated with 50 third-stage (L3) D. immitis larvae (ZoeLA) 30 days prior to the first treatment. Dogs were randomized to treatment (six animals in each group) with six monthly oral doses of placebo, Simparica Trio, Heartgard Plus, or Interceptor Plus at their respective label doses. Microfilaria (MF) and antigen tests were conducted periodically, and efficacy was evaluated by necropsy for adult heartworms approximately 9 months after L3 inoculation. RESULTS: Adult heartworms were recovered from all six placebo dogs, with a geometric mean of 35.5 worms (range, 23-48). Five of the six dogs treated with Simparica Trio were infected with a geometric mean of 1.0 worms (range, 0-3), and all remained MF-negative. All Heartgard Plus-treated dogs (six) were infected with a geometric mean of 32.5 worms (range, 22-38); five of these dogs were MF-positive at day 236. All Interceptor Plus-treated dogs (six) were infected with a geometric mean of 22.8 worms (range, 10-34); five of these dogs were MF-positive at day 236. The efficacy of six consecutive doses with Simparica Trio, Heartgard Plus, and Interceptor Plus against ZoeLA was 97.2, 8.5, and 35.9%, respectively. Adult worm counts for the Simparica Trio-treated group were significantly lower (P < 0.0001) than placebo control, Heartgard Plus, and Interceptor Plus-treated groups. Adult worm counts for Heartgard Plus and Interceptor Plus were not significantly different from placebo (P > 0.05). CONCLUSIONS: Simparica Trio prevented microfilaremia in all dogs and was highly effective (97.2%) and significantly better than either Heartgard Plus (8.5%) or Interceptor Plus (35.9%) in preventing the development of the ZoeLA ML-resistant heartworm strain when administered for six consecutive months in this comparative laboratory efficacy study.

OBJECTIVES: To prospectively assess cognitive function, anthropomorphic measures, and bone mineral density in men receiving androgen deprivation therapy (ADT) for prostate cancer; explore relationships between cognitive function and central adiposity; and gather preliminary data from a personalized education, exercise, and nutrition intervention. SAMPLE & SETTING: 33 participants consented from a randomized controlled intervention trial. METHODS & VARIABLES: Neurocognitive performance and self-report of cognitive function were assessed at baseline and 6 and 12 months. Dual-energy x-ray absorptiometry (DEXA) scans were obtained at baseline and 6 months. RESULTS: No between-group differences in cognitive function were demonstrated. Increased visceral adiposity was not associated with decrements in visuospatial abilities. Significant increases in fat mass without increases in body mass index or waist-hip ratio provided further evidence for DEXA as the preferred central adiposity measure. IMPLICATIONS FOR NURSING: Well-powered prospective research is needed to fully characterize the effects of ADT on cognitive function and the potential benefits of exercise and nutrition-based interventions.

OBJECTIVES: Many cancer survivors report issues with cognitive function following diagnosis and treatment. The purpose of this single-arm pilot study was to test the feasibility and acceptability of virtual delivery of a cognitive rehabilitation intervention for participants in virtual groups. SAMPLE & SETTING: 37 adult cancer survivors reporting impaired cognitive function following primary treatment were enrolled from Cedars-Sinai Medical Center and affiliates, the University of Kansas Cancer Center, and the Masonic Cancer Alliance. METHODS & VARIABLES: Two cohorts attended six weekly virtual sessions and completed pre- and postintervention patient-reported outcome questionnaires designed to measure perceived cognitive function, loneliness, and determinants of behavior change for exercise, sleep, and mindfulness. RESULTS: Postintervention scores for perceived cognitive function, determinants of behavior change, and loneliness ratings significantly improved. IMPLICATIONS FOR NURSING: Evidence continues to build in support of cognitive rehabilitation interventions for cancer survivors. Nurses play an important role in terms of patient identification, participation, and facilitation.

BACKGROUND: Frunevetmab, a felinized antinerve growth factor monoclonal antibody, effectively decreases osteoarthritis (OA) pain in cats. OBJECTIVE: To evaluate the efficacy of frunevetmab given at monthly intervals in a randomized, placebo-controlled, parallel-group, double-blind superiority study. ANIMALS: Two hundred seventy-five client-owned cats with naturally-occurring OA pain and associated mobility impairment and disability. METHODS: Randomized, placebo-controlled, parallel-group, double-blind, superiority study. Following screening, cats received frunevetmab (nominal dose of 1.0 mg/kg, SC [effective dose range of 1.0-2.8 mg/kg]) or placebo on days 0, 28, and 56. Outcome measures were owner questionnaires and veterinary physical and orthopedic evaluations at days 28, 56, and 84. Success/failure rates (and numbers needed treat, NNT) and change in scores (and standardized effect size, ES) were analyzed. RESULTS: Frunevetmab (182) and placebo (93) treated cats were enrolled and received at least 1 treatment. Significant improvement with frunevetmab over placebo occurred at days 28 and 56 for the client specific outcome measures (CSOM) questionnaire (success rates and total scores [NNT of 9 and ES of 0.3 at day 56]); at days 28 and 56 for owner-assessed global treatment response; and at days 56 and 84 for veterinarian-assessed joint pain (ES of 0.18 at day 56). Adverse events did not differ between groups, except skin disorders which collectively occurred significantly more frequently in frunevetmab treated (32/182 cats) vs placebo (8/93 cats). CONCLUSIONS AND CLINICAL IMPORTANCE: Frunevetmab has the potential to address a critical gap in the treatment of pain because of osteoarthritis in cats.
