Digitizing Survivorship Care Plans Through the POST-Treatment Health Outcomes of Cancer Survivors (POSTHOC) Mobile App: Protocol for a Phase II Randomized Controlled Trial.

BACKGROUND: Survivorship care plans (SCPs) are provided at the completion of cancer treatment to aid in the transition from active treatment to long-term survivorship. They describe the details of a patient's diagnosis and treatment and offer recommendations for follow-up appointments, referrals, and healthy behaviors. The plans are currently paper-based and become outdated as soon as a patient's health status changes. There is a need to digitize these plans to improve their accessibility, modifiability, and longevity. With current technology, SCPs can be linked to mobile devices and activity trackers so that patients can track health behaviors and compare them to their clinical goals, taking charge of their own health. OBJECTIVE: A mobile app, POSTHOC (POST-Treatment Health Outcomes of Cancer Survivors), that digitizes the SCP was developed, with goals of integrating it with wearable technologies and electronic medical records. Herein, we are conducting a randomized controlled trial that evaluates the POSTHOC app versus the traditional SCP on total symptom burden in the early posttreatment period. METHODS: We will recruit 54 patients who have recently completed curative therapy for cancer (any type) in person and remotely. They will be randomized 2:1, POSTHOC:usual care (unblinded). Those randomized to the POSTHOC group will receive their SCP via the app and will choose to focus on nutrition or exercise for the duration of the study based on their individual plan and personal preferences. Those randomized to the control group will get a paper-based plan. At baseline, 6 weeks, and 12 weeks, we will evaluate patient-reported outcomes, including total symptom burden (web-based questionnaire), diet (24-hour Automated Self-Administered [ASA24]), and physical activity (Fitbit Charge 6 [Google LLC]). We will also collect quantitative and qualitative feedback on the usability of the app from those in the POSTHOC arm to improve the app for future implementation studies, with a specific focus on patient-provider communication. For feasibility, we will calculate the percentage of patients who used the POSTHOC app at least 3 times per week. We will use linear mixed models to evaluate the effects of the POSTHOC app versus those of usual care on other outcomes at weeks 6 and 12. RESULTS: This trial is open to accrual in the University of Maryland Medical System as of March 2024, and as of July 3, 2024, a total of 20 participants have consented. CONCLUSIONS: This study is among the first to digitize the SCP in a mobile app and test the effects of a mobile health-delivered behavioral health intervention on symptom burden in cancer survivors. Our results will provide evidence about the effects of health self-management on symptoms. This knowledge will be integral to larger randomized controlled studies, integration with the electronic medical record, and nationwide implementation.

Transport and transformations of cadmium in water-biofilm-sediment phases as affected by hydrodynamic conditions.

Hydrodynamic conditions play a crucial role in governing the fate, transport, and risks of metal elements. However, the contribution of hydrodynamic conditions to the fate and transport of heavy metals among water, sediment, and biofilm phases is poorly understood. In our study, we conducted experiments in controlled hydrodynamic conditions using a total of 6 two-phase and 9 three-phase mesocosms consisting of water, biofilm, and sediment. We also measured Cd (cadmium) specification in different phases to assess how hydrodynamic forces control Cd bioavailability. We found that turbulent flow destroyed the surface morphology of the biofilm and significantly decreased the content of extracellular polymeric substances (p < 0.05). This led to a decrease in the biofilm's adsorption capacity for Cd, with the maximum adsorption capacity (0.124 mg/g) being one-tenth of that under static conditions (1.256 mg/g). The Cd chemical forms in the biofilm and sediment were significantly different, with the highest amount of Cd in the biofilm being acid-exchangeable, accounting for up to 95.1% of the total Cd content. Cd was more easily released in the biofilm due to its weak binding state, while Cd in the sediment existed in more stable chemical forms. Hydrodynamic conditions altered the migration behavior and distribution characteristics of Cd in the system by changing the adsorption capacity of the biofilm and sediment for Cd. Cd mobility increased in laminar flow but decreased in turbulent flow. These results enhance our understanding of the underlying mechanisms that control the mobility and bioavailability of metals in aquatic environments with varying hydrodynamic conditions.

Sulfidated nanoscale zero-valent iron derived from iron sludge for tetracycline removal: Role of sulfur and iron in reactivity and mechanisms.

Iron sludge, produced during the drinking water treatment process, can be recycled as potential iron resource to create environmental functional material. In this study, sulfur-iron composites derived from iron sludge (S-Fe composites) was synthesized through sulfidation and carbonization, and used for the tetracycline (TC) removal under aerobic and anoxic conditions. The reactivities of these as-prepared products were strongly depended on pyrolysis temperatures. In particular, sulfidated nanoscale zero-valent iron loaded on carbon (S-nFe0@CIS) carbonized at 800 °C exhibited the highest TC removal efficiency with 86.6% within 30 min at circumneutral pH compared with other S-Fe composites. The crystalline structure of α-Fe0, FeSx and S0 as main active sites in S-nFe0@CIS promoted the degradation of TC. Moreover, the Fe/S molar ratios significantly affected the TC removal rates, which reached the best value as the optimal S/Fe of 0.27. The results illustrated that the optimized extent of sulfidation could facilitate electron transfer from nFe0 towards contaminants and accelerate Fe(III)/Fe(II) cycle in reaction system compared to bared nFe0@CIS. We revealed that removal of TC by S-nFe0@CIS in the presence of dissolved oxygen (DO) is mainly attributed to oxidation, adsorption and reduction pathways. Their contribution to TC removal were 31.6%, 25.2% and 28.8%, respectively. Furthermore, this adsorption-oxygenation with the formation of S-nFe0@CIS-TC* complexes was a surface-mediated process, in which DO was transformed by the structural FeSx on complex surface to •OH with the generation of H2O2 intermediate. The intermediates of TC and toxicity analysis indicate that less toxicity products generated through degradation process. This study provides a new reclamation of iron sludge and offers a new insight into the TC removal by S-nFe0@CIS under aerobic conditions.

Preliminary evaluation of novel Bodily Attention Task to assess the role of the brain in chemotherapy-induced peripheral neurotoxicity (CIPN).

Chemotherapy-induced peripheral neurotoxicity (CIPN) is a common, sometimes dose-limiting side effect of neurotoxic chemotherapy. Treatment is limited because its pathophysiology is poorly understood. Compared to research on peripheral mechanisms, the role of the brain in CIPN is understudied and it may be important to develop better treatments. We propose a novel task that assesses brain activation associated with attention to bodily sensations (interoception), without the use of painful stimulation, to understand how CIPN symptoms may be processed in the brain. The goals of this preliminary study were to assess, 1) feasibility of the task, 2) sensitivity to changes in brain activity, and 3) suitability for assessing relationships between brain activation and CIPN severity. Eleven participants with varying types of cancer completed a brain fMRI scan and rated CIPN severity (CIPN-20) before and/or 12 weeks after starting neurotoxic chemotherapy. The Bodily Attention Task is a 7.5-min long fMRI task involving attentional focus on the left fingertips, the heart, or a flashing word "target" for visual attention (reference condition). Feasibility was confirmed, as 73% of all data collected were usable and participants reported feeling or focus during 75% of the trials. Regarding brain activity, finger attention increased activation in somatosensory regions (primary sensory cortex, insula) and sensory integration regions (precuneus, dorsolateral prefrontal cortex). Exploratory analyses suggested that brain activation may be associated with CIPN severity. A larger sample size and accounting of confounding factors is needed to test for replication and to identify brain and interoceptive biomarkers to help improve the prediction, prevention, and treatment of CIPN.

Spirituality moderates the relationship between cancer caregiver burden and depression.

OBJECTIVES: Cancer has become a chronic disease that requires a considerable amount of informal caregiving, often quite burdensome to family caregivers. However, the influence of spirituality on the caregivers' burden and mental health outcomes has been understudied. This study was to examine how caregiver burden, spirituality, and depression change during cancer treatment and investigate the moderating role of spirituality in the relationship between caregiver burden and depression for a sample of caregivers of persons with cancer. METHODS: This secondary analysis used a longitudinal design employing 3 waves of data collection (at baseline, 3 months, and 6 months). Family caregivers completed the Caregiver Reaction Assessment, Spiritual Perspective Scale, and the PROMIS® depression measure. Linear mixed model analyses were used, controlling for pertinent covariates. RESULTS: Spirituality, total caregiver burden, and depression remained stable over 6 months. More than 30% of the caregivers had mild to severe depressive symptoms at 3 time points. There was evidence of overall burden influencing depression. Of note was a protective effect of caregivers' spirituality on the relationship between depression and caregiver burden over time (b = -1.35, p = .015). The lower the spirituality, the stronger the relationship between depression and burden, especially regarding subscales of schedule burden, financial burden, and lack of family support. SIGNIFICANCE OF RESULTS: Spirituality was a significant resource for coping with caregiving challenges. This study suggests that comprehensive screening and spiritual care for cancer caregivers may improve their cancer caregiving experience and possibly influence the care recipients' health.

Dietary Composition, Meal Timing, and Cancer-Related Fatigue: Insights From the Women's Healthy Eating and Living Study.

BACKGROUND: Cancer-related fatigue is difficult to treat, and dietary interventions are promising yet underused. OBJECTIVE: We explored associations between dietary patterns and fatigue, and the effect of a dietary intervention versus control on fatigue using Women's Healthy Eating and Living study data, plus mediators and moderators of the intervention effect. METHODS: The Women's Healthy Eating and Living study was a randomized controlled trial among early-stage breast cancer survivors. The 4-year intervention encouraged fruits, vegetables, fiber, and 15% to 20% calories from fat. Fatigue outcomes included a 9-item energy scale and a single-item tiredness question. Dietary quality was estimated using a modified Healthy Eating Index (24-hour dietary recall) and serum carotenoid concentrations. Nutrient timing was obtained from 4-day food logs. RESULTS: Among 2914 total participants, lower body mass index was associated with less tiredness and more energy at baseline (P < .001 for both). Earlier start and end times for daily eating windows were associated with less tiredness (P = .014 and P = .027, respectively) and greater energy (P = .006 and P = .102, respectively). The intervention did not lead to improvements in fatigue on average (P > .125). However, the intervention was more effective for participants who were younger, had fewer comorbidities, and did not have radiation treatment. Mediators included increases in serum carotenoids, increases in the modified Healthy Eating Index, and weight loss/maintenance. CONCLUSION: Diet quality and earlier eating windows were associated with less fatigue. IMPLICATIONS FOR PRACTICE: Programs that encourage high diet quality and a morning meal and discourage nighttime eating should be tested for efficacy in reducing cancer-related fatigue in survivorship.

Psychotropic Medication Use and Changes During Hospitalization for Older Adults Living With Dementia.

To describe the use of psychotropic medications among older hospitalized patients. This was a descriptive study using baseline data from the first 308 older patients in a function focused care intervention study. Age, gender, race, comorbidities, admitting diagnosis, and medications (antidepressants, antianxiety medications, anticonvulsants, dementia drugs, antipsychotics, sedative-hypnotics, and opioids) were obtained at baseline and discharge. To compare change over time, generalized estimating equations were used. Participants were mostly female (63%) and White (69%) and were 83.1 years old on average. Antidepressant, antianxiety, anticonvulsant, dementia medication, sedative-hypnotic, and opioid use remained essentially unchanged between admission and discharge. Antipsychotic medication use increased significantly from 16% to 21% at discharge. There was persistent use of psychotropic medication among hospitalized older adults living with dementia and little evidence of deprescribing. There was some indication of changes made during hospitalization that may be appropriate, even without a focused deprescribing initiative.

Heavy metal fraction, pollution, and source-oriented risk assessment in biofilms on a river system polluted by mining activities.

The Lanping Pb-Zn mine is the largest source of Pb and Zn ores in China, thus posing a great threat to local ecosystems and human health. A total of seven heavy metals (Zn, Pb, Ni, Cu, Cr, Cd, and As) in the Bijiang River near the Pb-Zn mine were measured in winter and summer to assess their spatial-temporal enrichment, ecological risk, and source-oriented health risk in periphytic biofilms. Positive matrix factorization (PMF) receptor model and clustering analysis were used to quantitatively identify pollution sources. The results of PMF were then imported into the health risk assessment to further determine the carcinogenic and noncarcinogenic risks of various pollution sources. The results indicated distinct seasonal patterns in metal concentrations, with much higher concentrations in winter. Sites near the Pb-Zn mine tailing reservoir exhibited higher metal contamination levels than other sites. A strong correlation between the enrichment factor and the levels of nonresidual fraction suggested that anthropogenic inputs were the main source of these metals. Mining industries (Cd, Zn, and Pb), natural sources (As, Ni, and Cu), and agricultural activities (Cr) were the primary sources of heavy metal pollution in biofilms, accounting for 44.43%, 33.32%, and 22.26% of the total metal accumulation, respectively. Moreover, the carcinogenic and noncarcinogenic risks via dermal contact of the studied elements in biofilms were typically acceptable. Notably, as concentration was the main factor influencing these risks in children and adults. This study provides evidence that natural epilithic periphyton may be a potential metal biomonitor in aquatic systems and provide supporting information for effective source regulation.

Intersectionality of Socioecological Factors Associated With Cognitive Function Among Older Women With HIV in the United States: A Structural Equation Model Analysis Using Data From the Women's Interagency HIV Study.

ABSTRACT: Increased life expectancy of people with HIV has health implications including the intersection of the long-term use of antiretroviral treatment, inflammatory events, and age-related immunosenescence. In a cross-sectional study utilizing using the Socio-Eecological Model, we identified pathways of cognitive function (CF) among 448 women with HIV, 50 years and older. A structural equation model showed the direct effects of mood (ß = -0.25, p < .01), comorbidities (ß = --0.13, p < .05), race (ß = --0.13, p < .05), and abuse (ß = 0.27, p < .001) on the latent variable CF. Substance and alcohol use, depressive symptoms, cigarette smoking, and the number of comorbidities are important considerations when designing interventions utilizing using a multi-level and intersectional lens to maximize positive CF outcomes.

Source apportionment and risk assessment of metal pollution in natural biofilms and surface water along the Lancang River, China.

Herein, surface water and periphytic biofilm samples were collected from 16 sites along the Lancang River, China, to assess the spatial distribution, enrichment factor (EF), potential ecological risk index (RI), and associated source-oriented health risks of heavy metal elements (As, Cd, Co, Cr, Cu, Ni, Pb, V, and Zn) in the samples. Results showed that the levels of heavy metals were significantly lower in the surface water samples than in the biofilm samples (one-way analysis of variance, p < 0.001). Moreover, 37.50 % of the biofilm samples were significantly polluted by these heavy metals with a mean EF of >5. As and V were the highest polluting metals, and the enrichment of Co and Ni were attributed to natural sources. RI assessment results showed a consistent ecological risk of As. Based on principal component analysis with multiple linear regression (PCA-MLR) and positive matrix factorization (PMF) models, the presence of heavy metal ions in the biofilm samples was largely attributed to industrial activities (PCA-MLR: 68.89 %; PMF: 76.39 %), followed by a mixed source of natural and agricultural activities (PCA-MLR: 18.12 %; PMF: 13.56 %), and traffic emissions (PCA-MLR: 12.99 %; PMF: 10.05 %). Both carcinogenic and noncarcinogenic risks for adults were negligible even though adults tended to be exposed to greater risk through ingestion. Source-specific risk evaluations indicated that industrial pollution was the most important source of health risks. Our findings highlight the potential threat of biofilms to the ecological and human health.

Older Adults' Perception on and Use of Patient Portals: A Comparative Analysis of Two Samples.

Older adults can benefit from using patient portals. Little is known whether perception of and use of patient portals differ among older adults in diverse healthcare contexts. This study analyzed the difference in perceived usability, self-efficacy, and use of patient portals between older adults recruited from a healthcare system (n = 174) and older adults recruited from nationwide communities (n = 126). A secondary data analysis was conducted using the data sets of two independent studies. A series of linear and ordinal logistic regression analyses were performed. The healthcare system sample had more health issues, higher levels of perceived usability and self-efficacy, and frequent use of patient portals compared with the community sample. This study indicates that efforts to improve usability of patient portals and self-efficacy are essential for all older adult users. The association between perceived usability and patient portal use was stronger in the community sample than in the healthcare system sample, suggesting that approaches to support older adults' efficient use of patient portals should be tailored to their health status and care needs. Future studies may include inpatient and outpatient portals and investigate the impact on health outcomes of older adults across care settings.

Dietary Consumption Among Youth with Antipsychotic-Induced Weight Gain and Changes Following Healthy Lifestyle Education.

Background: Youth treated with antipsychotic medications are high risk for weight gain, increased lipids/glucose, and development of metabolic syndrome. Little is known about the dietary intake/nutritional adequacy in this vulnerable population, and effect on weight gain. This secondary data analysis describes the baseline intake and changes in diet after receiving healthy lifestyle education/counseling over 6 months, in a sample of youth with antipsychotic-induced weight gain. Methods: The U.S. Department of Agriculture (USDA) Automated Multiple-Pass Method 24-hour dietary recall was administered to 117 youth at baseline, 3 months, and 6 months. Parent/child received personalized healthy lifestyle education sessions over 6 months. Baseline intake was compared with the USDA Recommended Daily Allowance using independent samples t-tests. Individual dietary covariates were examined for change over 6 months using longitudinal linear mixed modeling. Influence of each on body mass index (BMI) z-score change was tested in a pooled group analysis and then compared by treatment group. Results: Pooled analysis revealed baseline consumption high in carbohydrates, fat, protein, sugar, and refined grains, while low in fruit/vegetables, whole grains, fiber, and water. Change over 6 months demonstrated a statistically significant decrease in daily calories (p = 0.002), carbohydrates (p = 0.003), fat (p = 0.012), protein (p = 0.025), sugar (p = 0.008), refined grains (p = 0.008), total dairy (p = 0.049), and cheese (p = 0.027). Small increases in fruits/vegetables were not statistically significant, although the Healthy Eating Index subscores for total vegetables (p = 0.013) and dark green/orange vegetables (p = 0.034) were. No dietary covariates were predictors of change in BMI z-score. Nondietary predictors were parent weight/BMI and treatment group, with the metformin and switch groups experiencing significant decreases in BMI z-score. Conclusions: Further pediatric studies are necessary to assess the effects of antipsychotic medications on dietary intake, and test efficacy of healthy lifestyle interventions on change in nutrition. The relationship of nutrition to cardiometabolic health in this population must be further investigated. Clinical Trial Registration number: NCT02877823.

Caregiver burden and related factors during active cancer treatment: A latent growth curve analysis.

PURPOSE: Caregiver burden is frequently studied cross-sectionally, but longitudinal studies on family caregiver burden during active cancer treatment are lacking. The goals of this study were to characterize trajectories of caregivers' burden during a 6-month active treatment period, and to examine which predictors are associated with their burden. METHOD: This study was a secondary analysis of data from a prospective study. A sample of 112 family caregivers of patients receiving cancer treatment were assessed at three time points (the initiation of new treatment regimen, 3-, and 6-month follow-up). Caregivers completed measures: Caregiver Reaction Assessment and Mutuality Scale of the Family Care Inventory. Data were analyzed using latent growth curve modeling. RESULTS: The two highest burdens were subdomains related to disrupted schedule and financial problems. Models showed a decline in schedule burden over time, yet total burden and other subscales (financial problems, health problems, and lack of family support and self-esteem) remained relatively stable. In multivariate analysis, mutuality, the relationship quality between patients and caregivers was inversely related to burden at baseline. Being a spouse, a sole caregiver and lower income were related to higher burden over time. CONCLUSIONS: Our findings confirmed significant determinants of caregiver burden over the course of active treatment. It is important for health care providers to be attentive to vulnerable caregivers who are at higher risk of elevated burden over time. Considering the multidimensional nature of caregiver burden, early assessment and tailored support programs may be effective by focusing on patient-caregiver relationships, caregiving roles, and income.

Remission from nicotine dependence among people with severe mental illness who received help/services for tobacco/nicotine use.

OBJECTIVES: A growing body of evidence supports pharmacological interventions to assist smoking cessation in people with severe mental illness (SMI); that is, lifetime major depressive disorder, bipolar disorders, or schizophrenia. Little is known about whether behavioral services are also associated with high probability of remission from nicotine dependence as compared to other types of help/services received (pharmacological, behavioral, or both). METHODS: A sample of 726 American lifetime adult smokers with SMI and a history of nicotine dependence, who received help/services for tobacco/nicotine use, were identified. These data came from a limited public use dataset, the 2012-2013 NESARC-III. Survival analysis was used to compare the probability of remission from nicotine dependence and the time needed for full remission from nicotine dependence by type of help/services received for tobacco/nicotine use. RESULTS: Remission was more frequent among those who received behavioral services. In addition, the average time from onset of nicotine dependence until full remission from nicotine dependence was shorter among those who received behavioral services. CONCLUSIONS: The current study suggests a clinical need for behavioral interventions to promote the probability of remission from nicotine dependence among smokers with SMI. Health care providers could play a role in educating and encouraging smokers with SMI to seek and utilize behavioral services.

Spirituality among family caregivers of cancer patients: The Spiritual Perspective Scale.

Spirituality is a critical resource for family caregivers of patients with cancer. However, studies on spirituality are hampered because measures of spirituality lack consistency and have not been validated in cancer caregivers. This study examined the validity of the Spiritual Perspective Scale (SPS) among cancer caregivers and explored whether measurement bias may influence differences in spirituality across caregiver and patient characteristics. In this secondary analysis, 124 caregivers of cancer patients were used to evaluate the validity of the 10-item SPS. A multiple indicators multiple causes model was applied to explore differences in the association between a latent spirituality factor and characteristics of caregivers and patients. Overall reliability of the SPS was adequate (Cronbach's α = .95). The SPS scores were predictive of higher meaning and purpose (r = .32, p = .004) and lower depression (r = -.22, p = .046) at 3-month follow-up. Construct validity of the SPS with a single-factor structure was supported in cancer caregivers. Adjusting for a direct effect of race did not alter the pattern of results, and caregivers who were older, female, ethnic minorities, less-educated, affiliated with a religion, and who provided care to another individual in addition to the patient had greater levels of spirituality. This study provides evidence for psychometric validation of the SPS in cancer caregivers. Understanding differences in caregivers' spirituality by using the SPS with psychometrically acceptable properties and minimal measurement bias deserves more attention to optimize spirituality assessment and support in cancer caregiving.

Circadian activity rhythms and fatigue of adolescent cancer survivors and healthy controls: a pilot study.

STUDY OBJECTIVES: The primary objective of this study was to compare circadian activity rhythms (CARs) of adolescents within 5 years of completing cancer treatment (survivors) with that of healthy adolescent controls. Secondary objectives were to explore differences in the relationship of CARs and fatigue between survivors and controls and between early survivors (<12 months posttreatment) and late survivors (≥12 months posttreatment). METHODS: Twenty-nine survivors and 30 controls, aged 13-18 years, participated in this prospective, descriptive pilot study. Adolescents and their parents completed a baseline measure of adolescents' fatigue. Adolescents wore a wrist actigraph continuously for 7 days and concurrently kept a sleep diary. Activity data recorded by actigraphy were fitted to an extended cosine model to calculate six CAR variables: acrophase, amplitude, midline estimating statistic of rhythm (MESOR), up-MESOR, down-MESOR, and F-statistic. Linear mixed models explored the relationship between CARs and fatigue. RESULTS: There were no group differences on CAR or fatigue measures. Among survivors, earlier down-MESOR was associated with greater parent-reported fatigue (P = .020), and earlier acrophase (P = .023) and up-MESOR (P = .025) were associated with greater adolescent-reported fatigue. Significant CAR-by-time posttreatment interaction effects were found on fatigue between early and late survivors. Among controls, greater parent-reported fatigue was associated with greater MESOR (P = .0495). CONCLUSIONS: Survivors within the first 5 years posttreatment were similar to controls in CARs and fatigue, suggesting robust recovery of circadian rhythms posttreatment. Different CAR characteristics were associated with fatigue in survivors and controls. Time posttreatment influenced the relationship between CARs and fatigue for survivors, with significant effects only for early survivors.

Relationship between circadian activity rhythms and fatigue in hospitalized children with CNS cancers receiving high-dose chemotherapy.

PURPOSE: Robust circadian rhythms are increasingly recognized as essential to good health. Adult cancer patients with dysregulated circadian activity rhythms (CAR) experience greater fatigue, lower responsiveness to chemotherapy, and shorter time to relapse. There is scant research describing circadian rhythms and associated outcomes in children with cancer. As part of a larger study examining whether a cognitive-behavioral intervention could preserve sleep in children and adolescents with central nervous system cancers hospitalized for high-dose chemotherapy (HDCT), this study aimed to compare CAR of these children to published values and to investigate the relationship between CAR and fatigue. METHODS: Participants aged 4-19 years wore an actigraph throughout their hospitalization (5 days). From activity counts recorded by actigraphy, six CAR variables were calculated: amplitude, 24-h autocorrelation (r24), dichotomy index (I < O), interdaily stability (IS), intradaily variability (IV), and acrophase. Parent-reported child fatigue and child/adolescent self-reported fatigue measures were collected daily. RESULTS: Thirty-three participants were included. Three CAR variables (amplitude, r24, and I < O) showed dysregulation compared to published values. Older age was significantly associated with later acrophase and greater dysregulation of all other CAR variables. Controlling for age, more dysregulated amplitude (p = 0.001), r24 (p = 0.003), IS (p = 0.017), and IV (p = 0.001) were associated with higher parent-reported fatigue; more dysregulated IV (p = 0.003) was associated with higher child-reported fatigue. CONCLUSIONS: Participants demonstrated dysregulated CAR during hospitalization for HDCT. Greater dysregulation was associated with greater fatigue. Research on circadian dysregulation and its relationship to health-related outcomes in children with cancer, and interventions to support circadian rhythmicity, is urgently needed.

Testing the Impact of a Cancer Survivorship Patient Engagement Toolkit on Selected Health Outcomes.

OBJECTIVES: To evaluate an interactive electronic Cancer Survivorship Patient Engagement Toolkit (CaS-PET) using a single-group pre-/post-test design. SAMPLE & SETTING: 30 cancer survivors with a mean age of 56.5 years (SD = 13.6) were recruited from the University of Maryland Medical Center in Baltimore. METHODS & VARIABLES: CaS-PET was designed to deliver survivorship care plans (SCPs) with multifactorial support and comprised of SCPs, biweekly follow-up using patient portal e-messages, and online resources. Outcomes included health-related quality of life, symptom burden, impact of cancer, fear of recurrence, physical activities, dietary behavior, patient-provider communication, adherence to treatment, and e-health literacy. RESULTS: At three months, there was a significant improvement in quality of life, physical symptom burden, and total symptom burden. IMPLICATIONS FOR NURSING: Findings suggest an excellent potential for using CaS-PET for survivors who are in transition from treatment to survivorship.

A pilot randomized controlled trial to improve sleep and fatigue in children with central nervous system tumors hospitalized for high-dose chemotherapy.

OBJECTIVES: To determine whether a sleep intervention compared with standard of care (SOC) was successful in preserving nighttime sleep in children with central nervous system cancers hospitalized for high-dose chemotherapy (HDCT) and autologous stem cell rescue, and to explore associations between sleep and fatigue during treatment. METHODS: An unblinded, randomized, controlled, multicomponent intervention (NCT00666614) including evidence-based cognitive and behavioral strategies to improve sleep was implemented in 33 children (age 4-12 years) and adolescents (age 13-19 years) during hospitalization. Children wore an actigraph to measure sleep and wake, and reported fatigue scores daily. Parents concurrently kept a sleep diary and reported fatigue scores for their children. RESULTS: The mean age was 9.5 ± 3.9 years, 81.8% were white, and 60.6% were male. Sleep in all children was seriously disturbed throughout the study. Children in the intervention group maintained their longest nighttime sleep across the study, while it declined in children receiving SOC (P = 0.009 for interaction). There were few other differences in sleep between groups. Controlling for age and baseline fatigue, higher nighttime activity score, and lower percent sleep were significantly associated with higher next-day adolescent-reported fatigue (P < 0.05); longest sleep was significantly positively associated with next-day child-reported fatigue (P = 0.018). CONCLUSION: In this sample of children undergoing HDCT, a multicomponent sleep intervention modestly preserved nighttime sleep duration, although overall sleep was poor in both groups. Sleep is an integral component of health, and may influence outcomes of children receiving HDCT. Further investigation into methods of preserving sleep in children undergoing intensive cancer therapy is warranted.

The worksite heart health improvement project's impact on behavioral risk factors for cardiovascular disease in long-term care: A randomized control trial.

BACKGROUND: Long-term care workers are at high risk for cardiovascular disease, in part because of their poor health habits. OBJECTIVE: The purpose of this study is to test the impact of the Worksite Heart Health Improvement Project (WHHIP) on subjective behavioral cardiovascular risk factors over time among long-term care staff. DESIGN: The WHHIP was a 12-month cluster randomized control trial conducted in four long-term care facilities. The exercise, nutrition, and stress management intervention lasted 9-months and was implemented during paid work time. SETTING AND PARTICIPANTS: Ninety-eight long-term care workers consented to participate in the study. METHODS: Survey data included: mood, dietary salt intake, dietary fat intake, sleep quality, and sleep duration. RESULTS: A significant positive short-term intervention effect at 9-month (p = .037) and long-term effect at 12-month for mood (p = .039) was found, signifying reduction in mood symptoms in the treatment group over time. The intervention group also showed longer sleep time (p = .016) and better sleep quality (p = .046) at 12-months. The intervention group had less dietary sodium intake at 9-months (p = .036); yet, this was not maintained over time. CONCLUSION: The WHHIP demonstrated the ability to improve participants' mood, sleep and sodium intake over time. Lessons learned particularly the challenges faced implementing the WHHIP and the solutions recommended provide critical insights to strengthen future programs with this population.
