Sleep disruption in hematopoietic cell transplantation recipients: prevalence, severity, and clinical management

Psychoneuroimmunology in multiple myeloma and autologous hematopoietic stem cell transplant: Opportunities for research among patients and caregivers

Multiple myeloma (MM) is an incurable cancer and is the leading indication for autologous hematopoietic stem cell transplantation (HSCT). To be eligible for HSCT, a patient must have a caregiver, as caregivers play a central role in HSCT preparation and recovery. MM patients remain on treatment indefinitely, and thus patients and their caregivers face long-term challenges including the intensity of HSCT and perpetual therapy after transplant. Importantly, both patients and their caregivers show heightened depressive and anxiety symptoms, with dyadic correspondence evidenced and caregivers' distress often exceeding that of patients. An extensive psychoneuroimmunology (PNI) literature links distress with health via immune and neuroendocrine dysregulation as well as biological aging. However, data on PNI in the context of multiple myeloma - in patients or caregivers - are remarkably limited. Distress in MM patients has been associated with poorer outcomes including higher inflammation, greater one year post-HSCT hospital readmissions, and worse overall survival. Further, anxiety and depression are linked to biological aging and may contribute to the poor long-term health of both patients and caregivers. Because MM generally affects older adults, individual differences in biological aging may represent an important modifier of MM biology and HSCT treatment outcomes. There are a number of clinical scenarios in which biologically younger people could be prescribed more intensive therapies, with potential for greater benefit, by using a personalized cancer therapy approach based on the quantification of physiologic reserve. Further, despite considerable psychological demands, the effects of distress on health among MM caregivers is largely unexamined. Within this context, the current critical review highlights gaps in knowledge at the intersection of HSCT, inflammation, and biological aging in the context of MM. Research in this area hold promise for opportunities for novel and impactful psychoneuroimmunology (PNI) research to enhance health outcomes, quality of life, and longevity among both MM patients and their caregivers.

Sleep Quality in Patients With Ocular Graft-Versus-Host Disease After Allogeneic Hematopoietic Stem Cell Transplantation

OBJECTIVES

To investigate the sleep quality in patients with ocular graft-versus-host disease (oGVHD) compared with patients without oGVHD after allogeneic hematopoietic stem cell transplantation (alloHCT) and healthy controls.

METHODS

This cross-sectional study analyzed 142 patients after alloHCT including 94 patients with oGVHD and 48 without. Fifty healthy controls were also enrolled. oGVHD was diagnosed according to International Chronic Ocular GVHD Consensus Group (ICOGCG) criteria. Sleep quality was assessed by the Chinese version of the Pittsburgh Sleep Quality Index (CPSQI). Poor sleep quality was defined as CPQSI score greater than 6.

RESULTS

Patients after alloHCT demonstrated a significantly higher CPQSI score than those of controls {7.0 [interquartile range (IQR) 5.0-10.0] vs. 5.5 [IQR 4.8-7.0], P =0.002}, especially in the oGVHD subgroup (7.5 [IQR 5.0-11.0] vs. 6.0 [IQR 5.0-8.0], P =0.04) with nearly double prevalence of poor sleep quality (58 [62%] vs. 18 [37%], P =0.006). Poor sleep quality was strikingly correlated with oGVHD diagnosis (adjusted odds ratio [OR]=2.55, 95% confidence interval [CI]: 1.02-6.34, P =0.04) and systemic immunosuppressants (adjusted OR=2.61, 95% CI: 1.32-5.71, P =0.02). Among the ocular parameters, poor sleep quality was significantly associated with higher ICOGCG score (adjusted OR=1.20, 95% CI: 1.03-1.39, P =0.02) and lower tear film break-up time (adjusted OR=0.85, 95% CI: 0.74-0.99, P =0.05).

CONCLUSIONS

Poor sleep quality was associated with an increased severity of oGVHD and tear film instability in the long-term alloHCT survivorship.

Acupuncture improves certain aspects of sleep in hematopoietic stem cell transplantation patients: a secondary analysis of a randomized controlled trial

BACKGROUND

High-dose chemotherapy followed by hematopoietic stem cell transplantation (HSCT) is associated with a high symptom burden including sleep disturbance. Here we present the results of a secondary analysis of a randomized, sham-controlled trial assessing the effect of acupuncture on sleep quality during HSCT.

METHODS

Adult multiple myeloma patients undergoing inpatient and outpatient autologous HSCT were randomized and blinded to receive either true or sham acupuncture (by licensed acupuncturists) once daily for 5 days starting the day after chemotherapy. Sleep onset, total sleep time, sleep efficiency percentage and sleep-onset latency time were assessed using an actigraphy-based sleep monitor. A multivariate regression analysis was conducted to compare the average area-under-the-curve of five acupuncture intervention days for each sleep outcome between groups, adjusted by baseline score and inpatient or outpatient chemotherapy stratum.

RESULTS

Over 32 months, 63 patients were enrolled. Participants undergoing true acupuncture experienced a significant improvement in sleep efficiency when compared to sham (-6.70, 95% CI -13.15, -0.25, p = 0.042). Subgroup analysis showed that the improvement was more prominent in the inpatient setting (-9.62, 95% CI -18.76, -0.47; p = 0.040). True acupuncture tended to improve wake time after sleep onset (WASO; -10.95, p = 0.054). Between-group differences in other sleep related variables were not statistically significant.

CONCLUSION

Our data suggest that true acupuncture may improve certain aspects of sleep, including sleep efficiency and possibly WASO, in multiple myeloma patients undergoing HSCT. By studying patient reported outcomes in future larger scale studies, acupuncture's role in improving sleep quality during HSCT treatment could be further elucidated.

Returning to employment following allogeneic hematopoietic stem cell transplant: A major problem among survivors

Quality of life (QoL) is an important aspect of cancer survivorship. One of the most acute problems that impact survivors in many aspects of activities of daily living and compromise their QoL is the inability to return to employment following successful cancer therapy. This is most prominent among survivors after allogeneic hematopoietic stem cell transplant (allo-HSCT). More than 50% of the survivors following allo-HSCT remain unemployed one year after the procedure. This problem extends beyond the initial few years; unemployment rates among those who underwent allo-HSCT during their childhoods or adolescence have remained high. The inability to return to employment imposes a financial burden. Survivors following allo-HSCT also experience a multitude of chronic psychosocial complications that may be both contributing and consequential to the inability to return to employment. However, many transplant programs and cancer centers do not have return-to-employment programs. In this review paper, we discuss the prevalence of unemployment following allo-HSCT. We examine the psychosocial symptoms experienced by survivors and how they may affect survivors' ability to return to employment. Finally, we propose a multi-disciplinary multi-pronged occupation-focused approach to address the complex and inter-related psychosocial symptoms to help alleviate the problem.

Developing a supportive and palliative care intervention for patients with allogeneic stem cell transplantation: protocol of a multicentre mixed-methods study (allo-PaS)

INTRODUCTION

Although allogeneic stem cell transplantation (allo-SCT) is a curative treatment for many haematological malignancies, it is often associated with a high morbidity and mortality. Yet, little is known about the needs for supportive and palliative care among allo-SCT recipients. Moreover, targeted interventions that reduce symptom burden and suffering are still lacking. The present study aims to inform a supportive-palliative care intervention for patients with allo-SCT and their informal carers by exploring their experience and assessing their needs, especially their existential concerns, regarding four research topics: symptom burden and quality of life; coexistence of a chance for cure and a relevant risk of dying; change in goals of care; dying phase.

METHODS AND ANALYSIS

This is a descriptive mixed-methods study in progress with a convergent parallel design. Data on the four research topics will be collected and analysed separately in three steps: (1) qualitative semi-structured interviews among 20 patients, 20 informal carers and 12 healthcare providers (HCPs) and focus groups among 12-24 HCPs; (2) a quantitative cross-sectional survey with validated questionnaires and self-developed questions among 100 patients, 100 informal carers and 50 HCPs; (3) a retrospective case analysis of all deceased patients who underwent an allo-SCT between 2010 and 2019, with collection of quantitative and qualitative data. The qualitative and quantitative data sets will be finally merged for comparison and interpretation. Results will serve to develop a supportive-palliative care intervention.

ETHICS AND DISSEMINATION

The Ethics Commission of the Faculty of Medicine of the University of Cologne approved this study (20-1370_2). The study results will be published in peer-review journals, be presented at congresses and will be translated into clinical practice through the development of the palliative-supportive care intervention.

Correlates of quality of life in South Korean patients undergoing hematopoietic stem cell transplantation based on the symptom management model

While hematopoietic stem cell transplantation (HSCT) has led to higher survival rates, the number of patients experiencing adverse reactions is also increasing. Based on the symptom management model, we aimed to analyze the relationships between symptom experience, symptom management strategies, self-management behavior, and quality of life among patients undergoing HSCT in South Korea and to identify the factors affecting their quality of life. The data of 67 conveniently sampled patients undergoing HSCT at a university-affiliated hospital, for the period from March 23 to June 7, 2016, were collected using a self-reported structured questionnaire. Data were analyzed using Pearson's correlations and multiple regression analysis. Quality of life showed a significant negative correlation with symptom experience and significant positive correlations with symptom management strategies. Factors influencing quality of life included symptom distress, symptom management strategies, and self-management behavior; these explained 39.4% of the variance. To improve quality of life in patients undergoing HSCT, the efficient management of multiple co-existing symptoms is important. There is a need for tailored nursing interventions based on a patient-focused and person-centered approach for patients undergoing HSCT.

Sleep-wake Disturbance following Allogeneic Hematopoietic Stem Cell Transplantation: Trajectory and Correlates.. [DOI: 10.21203/rs.3.rs-2055018/v1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0]

Adults undergoing allogeneic hematopoietic stem-cell transplant (HSCT) experience progressive physical and psychosocial distress in early stages post-HSCT, including sleep-wake disturbance (SWD), psychological distress, and fatigue. We conducted a longitudinal feasibility study to determine severity/trajectory of SWDs and investigated relationships among actigraphic sleep parameters, sleepiness, insomnia severity, fear of cancer recurrence (FCR), anxiety, depression, and fatigue at 100 (T1), 150 (T2), and 180 days (T3) post-HSCT. Eight adults enrolled. Median total sleep time (TST) at T1–T3 days was adequate (7.24, 7.17, and 7.09 hours), but sleep efficiency (SE) was suboptimal (78.9%, 78.5%, 83.67%). Median Epworth Sleepiness Scale (ESS) and Insomnia Severity Index (ISI) scores indicated minimal drowsiness and subclinical insomnia at T1–T3. Median FCR Inventory (FCRI) scores indicate diminishing FCR over time. Median scores across time for anxiety (48.05, 50.2, and 44.1) and depression (44.9, 41, and 41) suggest moderate–mild distress with slight fluctuations. Surprisingly, fatigue scores increased from T1–T3 (46, 50.9, and 52.1). Increases in ISI and FCRI scores were associated with modest increases in anxiety. Findings suggest the need to evaluate and address sleep, psychological distress, and fatigue in HSCT recipients. Larger studies to confirm prevalence of SWD and association with psychological factors are warranted.

Biobehavioral Implications of Covid-19 for Transplantation and Cellular Therapy Recipients

A growing body of literature has emphasized the importance of biobehavioral processes - defined as the interaction of behavior, psychology, socioenvironmental factors, and biological processes - for clinical outcomes among transplantation and cellular therapy (TCT) patients. TCT recipients are especially vulnerable to distress associated with pandemic conditions and represent a notably immunocompromised group at greater risk for SARS-CoV-2 infection with substantially worse outcomes. The summation of both the immunologic and psychologic vulnerability of TCT patients renders them particularly susceptible to adverse biobehavioral sequelae associated with the Covid-19 pandemic. Stress and adverse psychosocial factors alter neural and endocrine pathways through sympathetic nervous system and hypothalamic-pituitary-adrenal axis signaling that ultimately affect gene regulation in immune cells. Reciprocally, global inflammation and immune dysregulation related to TCT contribute to dysregulation of neuroendocrine and central nervous system function, resulting in the symptom profile of depression, fatigue, sleep disturbance, and cognitive dysfunction. In this article, we draw upon literature on immunology, psychology, neuroscience, hematology and oncology, Covid-19 pathophysiology, and TCT processes to discuss how they may intersect to influence TCT outcomes, with the goal of providing an overview of the significance of biobehavioral factors in understanding the relationship between Covid-19 and TCT, now and for the future. We discuss the roles of depression, anxiety, fatigue, sleep, social isolation and loneliness, and neurocognitive impairment, as well as specific implications for sub-populations of interest, including pediatrics, caregivers, and TCT donors. Finally, we address protective psychological processes that may optimize biobehavioral outcomes affected by Covid-19.

Long-term patient-reported neurocognitive outcomes in adult survivors of hematopoietic cell transplant

Long-term adult HCT survivors reported average cognitive quality of life compared with the general population.

Survivors with hearing issues and sleep impairments were more likely to report lower quality of life and impaired neurocognitive function.

Survivors of hematopoietic cell transplant (HCT) are at risk for neurocognitive impairments, which can negatively affect quality of life. Given limited studies, we aimed to describe the neurocognitive outcomes in a cohort of long-term adult HCT survivors. Eligible survivors (age ≥21 years at HCT and alive ≥2 years following HCT) completed a 60-question survey of neurocognitive function and quality of life, which included the Neuro-Quality of Life Cognitive Function Short Form (Neuro-QoL) and the Childhood Cancer Survivor Study Neurocognitive Questionnaire (NCQ). Analyses of risk factors included univariate comparisons and multivariable logistic regression. Survivors (n = 1861, 47.7% female, 65.6% allogeneic HCT) were surveyed at a median age of 64.2 years (interquartile range [IQR], 56.8-70.5) and a median 12.0 years (IQR, 6.0-21.0) from HCT. Survivors reported average Neuro-QoL scores (50.0 allogeneic; 49.2 autologous survivors) compared with an expected mean of 50 in the general population. On the NCQ, 17.4% to 31.2% of survivors reported impairments (Z-score >1.28) in task efficiency, memory, emotional regulation, or organization, compared with an expected 10% in the general population (all P < .01). In multivariable regression analyses, impaired Neuro-QoL (T-score <40) was independently associated with hearing issues (odds ratio [OR], 2.13; 95% confidence interval [CI], 1.46-3.10) and sleep impairment (OR, 4.41; 95% CI, 2.80-6.94) among allogeneic survivors, with comparable associations in autologous survivors. Overall, long-term adult HCT survivors reported average cognitive quality of life compared with the general population. Subsets of survivors with hearing issues and sleep impairments were more likely to report lower quality of life and impaired neurocognitive function, which may facilitate targeted monitoring or interventions following HCT.

Comparison of objective and subjective sleep time and quality in hospitalized recipients of hematopoietic stem cell transplantation

Objective

In this study, the sleep time and efficiency of recipients of hematopoietic stem cell transplantation (HSCT) were investigated throughout treatment and compared objective measurements with subjective self-reported data.

Methods

Sleep time and efficiency were measured using both objective and subjective methods throughout the treatment period in inpatients receiving HSCT. The participants were recruited among HSCT inpatients at a tertiary hospital in Seoul, South Korea, between August 2019 and August 2020. Actigraphy was used to measure objective sleep time and efficiency. Subjective sleep time and quality were measured using the sleep diary and Insomnia Severity Index. Measurement data from 40 patients were analyzed. Repeated-measures analysis of variance was used to compare the differences between objective and subjective values in total sleep time and sleep efficiency.

Results

The total sleep time was the lowest during the administration of anticancer drugs before stem cell transplantation. The total sleep time of patients with HSCT differed significantly over time when offsetting the difference in the measurement method. There were no significant differences between subjective and objective results for sleep time, and the interaction between the two methods over time was not significant. However, meaningful differences were found among the groups in sleep efficiency throughout the treatment period and between objective and subjective methods, as well as a statistically significant interaction between the two methods over time.

Conclusions

Actigraphy misclassified patients’ low-energy state with little movement due to immune system impairment during treatment as sleep, resulting in high measured sleep efficiency, whereas their self-reported sleep efficiency was very low. Therefore, subjective measures might be more accurate for measuring sleep efficiency in HSCT patients.

Insomnia in Post-Hematopoietic Stem-Cell Transplant Patients in Jordan: Prevalence and Associated Factors

Background and Objective Insomnia is a common symptom that is experienced by the patients post hematopoietic stem cell transplant that interfere with recovery outcomes and patients’ quality of life. Little is known about insomnia among post hematopoietic stem cell transplant in Jordan and in other Arab countries. The purpose of the current study was to identify the levels of insomnia and the related factors in post hematopoietic stem cell transplant.Methods A descriptive cross-sectional correlational design was used to guide this study. Data was collected from 163 patients by the Arabic version of the Insomnia Severity Index (ISI).Results The participant’s average ISI was 14.06 ± 7.71 indicating sub-threshold insomnia. Regarding the insomnia levels, 23.9% of the participants reported no insomnia, 27.6% had subthreshold insomnia, 31.3% had moderate clinical insomnia, and 17.2% had severe clinical insomnia. A significant difference in insomnia levels in some related factors was reported including the higher educated patients (t = 2.40, p = 0.018), patients who received allogeneic transplants (t = -2.932, p = 0.004), and patients within a 30 days’ post-transplant (F (160, 2) = 61.03, p < 0.001).Conclusions In conclusion, the overall prevalence of insomnia among post HSCT patients was 48.5% (n = 79) that suggested clinical insomnia, and it was affected by several clinical variables. Further studies are needed to provide appropriate interventions to decrease insomnia levels among patients.

Sleep Disruption, Fatigue, and Depression as Predictors of 6-Year Clinical Outcomes Following Allogeneic Hematopoietic Cell Transplantation

BACKGROUND

Allogeneic hematopoietic cell transplantation (HCT) is a widely used treatment for hematologic cancers, with survival rates ranging from 25% to 78%. Known risk factors for chronic graft-versus-host disease (cGVHD), a serious and common long-term complication, disease relapse, and mortality following HCT have been identified, but much of the variability in HCT outcomes is unexplained. Biobehavioral symptoms including depression, sleep disruption, and fatigue are some of the most prevalent and distressing for patients; yet research on biobehavioral risk factors for HCT outcomes is limited. This study evaluated patient-reported depression, sleep disruption, and fatigue as risk factors for cGVHD, disease relapse, and mortality.

METHODS

Adults receiving allogeneic HCT for a hematologic malignancy (N = 241) completed self-report measures of depression symptoms, sleep quality, and fatigue (severity, interference) pre-HCT and 100 days post-HCT. Clinical outcomes were monitored for up to 6 years.

RESULTS

Cox proportional hazard models (2-tailed) adjusting for patient demographic and medical characteristics revealed that high pre-HCT sleep disruption (Pittsburgh Sleep Quality Index >9; hazard ratio [HR] = 2.74, 95% confidence interval [CI] = 1.27 to 5.92) and greater post-HCT fatigue interference (HR = 1.32, 95% CI = 1.05 to 1.66) uniquely predicted increased risk of mortality. Moderate pre-HCT sleep disruption (Pittsburgh Sleep Quality Index 6-9) predicted increased risk of relapse (HR = 1.99, 95% CI = 1.02 to 3.87). Biobehavioral symptoms did not predict cGVHD incidence.

CONCLUSIONS

Biobehavioral symptoms, particularly sleep disruption and fatigue interference, predicted an increased risk for 6-year relapse and mortality after HCT. Because these symptoms are amenable to treatment, they offer specific targets for intervention to improve HCT outcomes.

Neurocognitive Impairment After Hematopoietic Stem Cell Transplant for Hematologic Malignancies: Phenotype and Mechanisms

Hematopoietic stem cell transplant (HSCT) plays a central role in the treatment of hematologic cancers. With the increasing survival of patients after HSCT, survivorship issues experienced by this population have become an important outcome. Cognitive impairment is an established sequela of HSCT, with studies to date establishing its presence, associated risk factors, and clinical phenotype. There are multiple potential contributors to cognitive impairment after HSCT. Efforts are ongoing to further characterize its clinical phenotype, associated biomarkers, and biologic underpinnings. A fundamental knowledge of post-HSCT cognitive impairment is of value for all clinicians who interface with this population, and further academic efforts are needed to more fully understand the impact of this cancer treatment on brain health. IMPLICATIONS FOR PRACTICE: As survival outcomes after hematopoietic stem cell transplant (HSCT) improve, an awareness of the post-treatment challenges faced by this population has become central to its care. HSCT can have a sustained and broad impact on brain health, causing cognitive dysfunction, fatigue, disturbed mood, and sleep. In affected patients, autonomy, return to work, relationships, and quality of life may all be affected. A fundamental fluency in this area is important for clinicians interfacing with HSCT survivors, facilitating the identification and management of cognitive dysfunction and concurrent symptom clusters, and stimulating interest in these sequelae as areas for future clinical research.

Biobehavioral Research and Hematopoietic Stem Cell Transplantation: Expert Review from the Biobehavioral Research Special Interest Group of the American Society for Transplantation and Cellular Therapy

Hematopoietic stem cell transplantation (HCT) is a potentially curative treatment for many hematologic conditions. Despite advances in conditioning and supportive measures, however, there remain significant comorbidities that threaten survivorship. Adverse effects of stress-related biobehavioral processes-defined here as the interactions of behavioral, psychological, and socioenvironmental factors with biology-impact immune recovery and function and are particularly salient in the HCT context, given the importance of immune reconstitution for improved survivorship. However, biobehavioral processes have been underinvestigated in this vulnerable group compared with other cancer populations. Here the Biobehavioral Research Special Interest Group (SIG) of the American Society for Transplantation and Cellular Therapy provides an expert review to inform research directions explicating the biological correlates of behavioral symptoms and evaluate the impact of these on HCT outcomes. The goal of this expert review is to provide a foundation for advancing science that effectively integrates behavioral and biological processes to optimize quality of life and improve clinical outcomes for HCT recipients.

What is known about palliative care in adult patients with allogeneic stem cell transplantation (allo-SCT)?

Patients undergoing allogeneic stem cell transplantation (allo-SCT) are given a real chance of cure, but at the same time are confronted with a considerable risk of mortality and of severe long-term impediments. This narrative, non-systematic literature review aims to describe the supportive and palliative care needs of allo-SCT recipients, including long-term survivors or those relapsing or dying after transplantation. It also evaluates the feasibility and effectivity of integrating palliative care early in transplant procedures. In this appraisal of available literature, the main findings relate to symptoms like fatigue and psychological distress, which appear to be very common in the whole allo-SCT trajectory and might even persist many years post-transplantation. Chronic GvHD has a major negative impact on quality of life. Overall, there is a paucity of research on further issues in the context of allo-SCT, like the distress related to the frequently unpredictable post-transplant trajectory and prognosis, as well as the end-of-life phase. First randomized controlled results support the effectiveness of early integration of specialized palliative care expertise into transplant algorithms. Barriers to this implementation are discussed.

Association Between Blood Heavy Metal Concentrations and Dyslipidemia in the Elderly

Our objective was to evaluate the relationship of blood metal levels including strontium, cadmium, lead, vanadium, aluminum, cobalt, and manganese with dyslipidemia in the elderly Chinese population. In this study, stratified cluster sampling was adopted in the elderly in two communities of Lu'an City from June to September 2016, and 1013 participants were finally included. The inductively coupled plasma mass spectrometry (ICP-MS) was used to measure the metals' concentrations in whole blood. After multivariable adjustment, the odds ratios (95% confidence interval [CI]) of dyslipidemia associated with the highest quartile of metal concentrations were 1.32 (0.89 ~ 1.96), 1.28 (0.83 ~ 1.97), 1.86 (1.23 ~ 2.80), 0.80 (0.55 ~ 1.16), 0.76 (0.51 ~ 1.13), 0.76 (0.53 ~ 1.11), and 1.14 (0.78 ~ 1.67) for strontium, cadmium, lead, vanadium, aluminum, cobalt, and manganese, respectively, compared with the lowest quartile. After reducing the dimensionality of metal elements by principal component analysis, we found that the combined exposure of aluminum, cobalt, and vanadium was the protective factor of non-dyslipidemia, while the combined exposure of cadmium, strontium, and lead was the risk factor of dyslipidemia.

Pediatric hematopoietic cell transplantation: Longitudinal trends in body mass index and outcomes

Pediatric recipients of HCT may have a high susceptibility for overweight and obesity, and obesity may negatively impact post-transplant mortality and survival. This is a single-center retrospective analysis of 297 pediatric patients who received HCT between 2005 and 2018. Patients were classified as UW, NW, OW, or OB based on age-adjusted BMI. A mixed-effects linear regression model controlling for patient, disease, and transplant-related characteristics was used to trend weight longitudinally. Comparisons were made between weight category and post-transplant outcomes. In the pretransplant period, 5.4%, 54.5%, 22.2%, and 17.8% of patients were UW, NW, OW, and OB, respectively. Five years post-transplantation, those numbers were 10.6%, 48.2%, 16.5%, and 24.7%. Overall, BMI increased 0.00094 ± 0.0001 kg/m² each day post-transplant (P < .001), with older individuals demonstrating greater rates of increase. Further, there was a larger BMI increase in patients without TBI compared with those who received TBI (1.29 ± 0.49, P = .008). Rates of acute GVHD, chronic GVHD, and viral infections, in addition to time to platelet and neutrophil engraftment and 5-year survival estimates, were not significantly different based on pretransplant BMI. Overweight and obese individuals had poorer 5-year survival based on 100-day post-transplant BMI (P = .02). Overall, pediatric HCT recipients are at risk of developing obesity, which is associated with decreased survival. Adolescents and young adults demonstrate the highest risk of weight gain, representing a vulnerable population that requires close monitoring, additional interventions, and further research.

Prevalence of decisional regret among patients who underwent allogeneic hematopoietic stem cell transplantation and associations with quality of life and clinical outcomes

BACKGROUND

Allogeneic hematopoietic stem cell transplantation (alloHCT) is potentially curative but with known negative effects on quality of life. In the current study, the authors investigated whether patients expressed regret after undergoing HCT and the relationships between clinical outcomes and quality of life.

METHODS

Center for International Blood and Marrow Transplant Research data from 184 adults who completed the Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT) before undergoing alloHCT and at day 100 were used. Additional time points were 6 months and 12 months. Regret was measured using a FACT-BMT item not included in scoring: "I regret having the bone marrow transplant." The authors evaluated FACT-BMT scores and regret using Student t-tests. Covariance pattern models were used to determine predictors of regret over time, including baseline characteristics and post-alloHCT outcomes (acute or chronic graft-versus-host-disease, disease recurrence).

RESULTS

At 100 days, 6 months, and 12 months, approximately 6% to 8% of patients expressed regret; a total of 15% expressed regret at any time point. Regret was found to be associated with lower FACT-BMT scores at 6 months and 12 months (P < .001). Higher baseline FACT-BMT and social well-being scores were associated with a reduced risk of expressing regret. The risk of regretting transplantation was 17.5 percentage points (95% confidence interval, 5.5-29.7 percentage points) greater in patients who developed disease recurrence after HCT compared with patients who did not.

CONCLUSIONS

Among patients who underwent alloHCT and lived to 100 days, the majority did not report regretting their transplantation. Regret was found to be related to disease recurrence. Social connectedness may serve as a protective factor against later regret. Future work should explore regret in other patient groups and use qualitative methods to inform best practices for reducing regret.

Patients’ quality of life: Validation of the functional assessment of cancer therapy-bone marrow transplant (FACT-BMT) instrument for the Mexican population

Objective

The functional assessment of cancer therapy-bone marrow transplant (FACT-BMT) is a widely used instrument to assess quality of life (QOL) in hematopoietic stem cell transplant (HSCT) patients, but there is little evidence of its validity in Latin American populations. This study evaluated the psychometric properties of the Spanish language version of the FACT-BMT in Mexican patients.

Method

First, the original version was piloted with 15 HSCT patients to obtain an adequate cultural version, resulting in the adaptation of one item. After that, the new version was completed by 139 HSCT patients.

Results

The results showed a FACT factor structure that explains 70.84% of the total variance, a factor structure similar to the original FACT structure, and with a high internal consistency (Cronbach's alpha = 0.867). For the BMT subscale, the best factor structure included 17 items which explain 61.65% of the total variance with an adequate internal consistency (Cronbach's alpha = 0.696).

Significance of the results

The FACT-BMT was found to be a valid and reliable instrument to evaluate QOL in Mexican patients. Our results constitute new FACT-BMT empirical evidence that supports its clinical and research uses.

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.

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.

Positive psychological experiences in allogeneic hematopoietic stem cell transplantation

OBJECTIVE

Positive psychological constructs (e.g., optimism and hope) have been associated with superior health outcomes in the recovery from hematopoietic stem cell transplantation (HSCT) in prior work. However, such studies have not examined a broad range of positive psychological constructs, their sources or evolution over time, or their connections with key health behaviors. We used semistructured qualitative interviews in 25 HSCT patients to explore the nature and sources of positive psychological experiences during the first 100 days after transplantation.

METHODS

Participants completed interviews during their HSCT hospitalization and approximately 100 days after transplantation. Transcribed interviews were organized and analyzed using NVivo 12 software by two coders (κ = 0.92). Interviews focused on the breadth of positive psychological experiences, their sources and evolution during the 100 days, and participants' perceived impact of positive constructs on health behaviors.

RESULTS

Several positive psychological constructs especially gratitude, determination, and optimism were frequently expressed. Family support and deliberate participation in pleasant and meaningful activities were the two primary sources of positive psychological experiences after HSCT. At baseline, participants consistently reported gratitude for their donors while follow-up was consistently characterized by hope for cure and return to baseline level of functioning. Additionally, participants related bidirectional relationships between positive psychological well-being experiences and completion of health behaviors over time.

CONCLUSIONS

As one of the first qualitative studies characterizing the breadth, sources, and evolution of positive psychological experiences in HSCT patients, these findings add to the literature aimed at understanding psychological well-being in this complex and growing patient population.

Psychological Considerations in Hematopoietic Stem Cell Transplantation

BACKGROUND

In recent decades, advances in transplantation medicine, and improved posttransplant care have reduced morbidity and mortality from hematopoietic stem cell transplantations (HSCTs). However, patients undergoing HSCT report a high prevalence of psychological distress, which can negatively impact recovery, function, and health outcomes, including mortality and higher risk of graft vs. host disease. Appropriate assessment and management of these psychological symptoms lead to better engagement with treatment and a variety of superior health outcomes.

OBJECTIVE

We provide a narrative review of the psychological challenges that accompany HSCT and suggest management approaches to equip psychiatric consultants involved in the care of this patient population.

METHODS

We reviewed published work in PubMed, PsycInfo, and Scopus electronic databases on the common psychological challenges in HSCT, their vulnerability factors, as well as practical interventions for managing these challenges.

RESULTS

We outline the phases of the HSCT hospitalization and discuss common psychological challenges, such as depression, delirium, and post-traumatic stress reactions that accompany HSCT. We suggest an approach to psychiatric consults during the HSCT hospitalization and discuss practical interventions for managing psychological challenges in this population.

CONCLUSIONS

Though pharmacological and behavioral interventions have been successfully used to treat psychosocial challenges in HSCT, further research is needed to understand the optimal psychiatric assessment tools, treatment strategies, and the long-term psychiatric care needed to address psychiatric comorbidities in this growing patient population.

Cancer survivors in the workplace: sleep disturbance mediates the impact of cancer on healthcare expenditures and work absenteeism

PURPOSE

History of cancer is significantly associated with increases in healthcare costs, worse work performance, and higher absenteeism in the workplace. This is particularly important as most cancer survivors return to employment. Sleep disturbance is a largely overlooked potential contributor to these changes.

METHODS

Data from 9488 state employees participating in the Kansas State employee wellness program were used to assess cancer history, sleep disturbance, healthcare expenditures, work performance ratings, and absenteeism. Participants were categorized as having had no history of breast or prostate cancer, a past history only with no current cancer treatment, or current treatment for breast or prostate cancer. Indirect mediation analyses determined whether sleep disturbance mediated the influence of cancer status on outcomes.

RESULTS

Employees receiving treatment for breast or prostate cancer had significantly greater healthcare expenditures and absenteeism than those with a past history or no history of cancer (ps < .0001). Sleep disturbance significantly mediated the impact of cancer on healthcare expenditures and absenteeism (ps < .05), accounting for 2 and 8% of the impact of cancer on healthcare expenditure and missed full days of work, respectively.

CONCLUSIONS

The worse outcomes observed among employees receiving treatment for breast and prostate cancer, the most common forms of cancer among women and men, were partially explained by the impacts of cancer and treatment for cancer on sleep disturbance. These findings suggest that preventing or addressing sleep disturbance may result in economic benefits in addition to improvements in health and quality of life.

Actigraphy assessment of sleep quality among patients with acute myeloid leukaemia during induction chemotherapy

Objectives

Patients receiving induction chemotherapy for acute myeloid leukaemia (AML) anecdotally describe poor sleep, but sleep disturbances have not been well-characterised in this population. We aimed to test the feasibility of measuring sleep quality in AML inpatients using a wearable actigraphy device.

Methods

Using the Actigraph GT3X ‘watch’, we assessed the total sleep time, sleep onset latency, wake after sleep onset, number of awakenings after sleep onset and sleep efficiency for inpatients with AML receiving induction chemotherapy. We assessed patient self-reported sleep quality using the Pittsburgh Sleep Quality Index (PSQI).

Results

Of the 12 patients enrolled, 11 completed all actigraphy and PSQI assessments, demonstrating feasibility. Patients wore the Actigraph device for a mean (SD) of 15.92 (8.3) days, and actigraphy measures suggested poor sleep. Patients had a median average awakening length of 6.92 min, a median number of awakenings after sleep onset of 4 and a median sleep onset latency of 10.8 min. Actual median sleep efficiency (0.91) was high, suggesting that patients’ poor sleep was not due to insomnia but perhaps due to interruptions, such as administration of medications, lab draws and vital sign measurements.

Conclusions

Collection of sleep quality data among inpatients with AML via a wearable actigraphy device is feasible. AML inpatients appear to have poor sleep quality and quantity, suggesting that sleep issues represent an area of unmet supportive care needs in AML. Further research in this areas is needed to inform the development of interventions to improve sleep duration and quality in hospitalised patients with AML.

Severity, course, and predictors of sleep disruption following hematopoietic cell transplantation: a secondary data analysis from the BMT CTN 0902 trial

Sleep disruption has received little attention in hematopoietic cell transplantation (HCT). The goal of this study was to describe severity, course, and predictors of sleep disruption following HCT. A secondary data analysis was conducted of the Blood and Marrow Transplantation Clinical Trials Network (BMT CTN) 0902 study. Participants completed a modified version of the Pittsburgh Sleep Quality Index prior to transplant and 100 and 180 days post-transplant. Growth mixture models were used to characterize subgroups of patients based on baseline sleep disruption and change over time. A total of 570 patients (mean age 55, 42% female) were included in the current analyses. Patients could be grouped into four distinct classes based on sleep disruption: 1) clinically significant sleep disruption at baseline that did not improve over time (20%); 2) clinically significant sleep disruption at baseline that improved over time (22%); 3) sleep disruption that did not reach clinical significance at baseline and did not improve over time (45%); and 4) no sleep disruption at baseline or over time (13%). These data provide a more comprehensive understanding of sleep disruption that can be used to develop interventions to improve sleep in HCT recipients.

Palliative care during and following allogeneic hematopoietic stem cell transplantation

PURPOSE OF REVIEW

The purpose of this review is to synthesize recent literature regarding the provision of palliative care to patients during and following allogeneic hematopoietic stem cell transplantation (HSCT), highlighting factors which mediate impairments in health-related quality of life in this patient population, and the intervention approaches and models of care delivery that clinicians can consider to address unmet needs for palliative care and to strengthen patient and family resiliency.

RECENT FINDINGS

Provision of palliative care simultaneous with the delivery of treatment directed at the underlying malignancy has emerged as a recommended practice for patients with advanced cancer and high-symptom burden, and a recent randomized trial demonstrates the effectiveness of early palliative care in reducing some of the symptom burden and mood disturbances associated with HSCT. Although more research is needed, there is an expanding body of research-tested interventions to ameliorate the physical and psychological morbidity of HSCT across the transplant trajectory.

SUMMARY

Palliative care interventions delivered by an interdisciplinary team that includes transplant clinicians and palliative care across the HSCT trajectory can alleviate physical and psychological morbidity, thereby improving the patient and family experience of HSCT.

Sleep disruption among cancer patients following autologous hematopoietic cell transplantation

Despite a high prevalence of sleep disruption among hematopoietic cell transplant (HCT) recipients, relatively little research has investigated its relationships with modifiable cognitive or behavioral factors or used actigraphy to characterize sleep disruption in this population. Autologous HCT recipients who were 6 to 18 months post-transplant completed self-report measures of cancer-related distress, fear of cancer recurrence, dysfunctional sleep cognitions, and inhibitory sleep behaviors upon enrollment. Patients then wore an actigraph for seven days and completed a self-report measure of sleep disruption on day seven of the study. Among the 84 participants (age M=60, 45% female), 41% reported clinically-relevant sleep disruption. Examination of actigraph data confirmed that, on average, sleep was disrupted (wake after sleep onset M=66 minutes) and sleep efficiency was less than recommended (sleep efficiency M=78%). Cancer-related distress, fear of recurrence, dysfunctional sleep cognitions, and inhibitory sleep behaviors were related to self-reported sleep disruption (p’s < .05) but not objective sleep indices. Results suggest that many HCT recipients experience sleep disruption after transplant. Cancer-related distress, fear of recurrence, dysfunctional sleep cognitions, and maladaptive sleep behaviors are related to self-reported sleep disruption and should be considered targets for cognitive behavioral intervention in this population.

Efficacy and Safety of the Traditional Herbal Medicine, Gamiguibi-tang, in Patients With Cancer-Related Sleep Disturbance: A Prospective, Randomized, Wait-List-Controlled, Pilot Study

Background: Sleep disturbance is the second most bothersome symptom in patients with cancer, and it can significantly impair their quality of life. The aim of this study was to investigate the efficacy and safety of the traditional herbal medicine Gamiguibi-tang (GGBT) in patients with cancer-related sleep disturbance. Methods: We conducted a prospective, randomized, wait-list-controlled, open-label pilot clinical trial on cancer-related sleep disturbance. Patients with cancer experiencing poor sleep quality with a Pittsburgh Sleep Quality Index of at least 6 were randomly assigned to the GGBT and wait-list groups to receive GGBT and conventional care, respectively, for 2 weeks. The primary endpoint was the Insomnia Severity Index (ISI) score. Fatigue, depression, and cognitive impairment were assessed as the secondary endpoints by using the Brief Fatigue Inventory (BFI), Beck Depression Inventory (BDI), and Montreal Cognitive Assessment (MoCA). Results: Thirty participants who met the eligibility criteria were enrolled. Sleep disturbance assessed using the ISI improved significantly more in the GGBT group than in the wait-list group (−5.5 ± 4.4 vs 0.1 ± 1.1, P < .001). Fatigue level determined using the BFI also improved significantly more in the GGBT group than in the wait-list group (−0.8 ± 0.8 vs 0.0 ± 0.3, P = .002). The BDI and MoCA scores showed no significant changes. Adverse events were reported in two patients in the GGBT group and consisted of mild dyspepsia and mild edema. Conclusion: GGBT may be a potential treatment option for cancer-related sleep disturbance. Further research is needed to investigate the efficacy and safety of GGBT.

National Institutes of Health Hematopoietic Cell Transplantation Late Effects Initiative: The Patient-Centered Outcomes Working Group Report

In 2015, the National Institutes of Health convened six working groups to address the research needs and best practices for late effects of hematopoietic stem cell transplantation survivors. The Patient-Centered Outcomes Working Group, charged with summarizing the HRQOL evidence base, used a scoping review approach to efficiently survey the large body of literature in adult and pediatric HCT survivors over 1 year after transplantation. The goals of this paper are to (1) summarize the current literature describing patient-centered outcomes in survivors, including the various dimensions of health-related quality of life affected by HCT, and describe interventions tested to improve these outcomes; (2) highlight areas with sufficient evidence allowing for integration into standard practice; (3) address methodological issues that restrict progress in this field; (4) identify major gaps to guide future research; and (5) specify priority research recommendations. Patient-centered outcomes were summarized within physical, psychological, social, and environmental domains, as well as for adherence to treatment, and health behaviors. Interventions to improve outcomes were evaluated for evidence of efficacy, although few interventions have been tested in long-term HCT survivors. Methodologic issues defined included lack of consistency in the selection of patient-centered outcome measures, along with the absence of a standard for timing, frequency, and mode of administration. Recommendations for HCT survivorship care included integration of annual screening of patient-centered outcomes, use of evidence-based practice guidelines, and provision of treatment summaries and survivorship care plans after HCT. Three priority research recommendations included the following: (1) design and test risk-targeted interventions with dose-intensity modulation matching the needs of HCT survivors with priority domains, including sexual dysfunction, fatigue, sleep disruption, nonadherence to medications and recommended health care, health behaviors including physical inactivity and healthy eating, and psychological dysfunction, with particular consideration of novel technologies to reach HCT survivors distant from their transplantation centers; (2) design a consensus-based methodologic framework for outcomes evaluation; and (3) evaluate and compare existing practices for integrating patient-centered outcome screening and interventions across HCT survivorship programs.

Cognitive problems following hematopoietic stem cell transplant: relationships with sleep, depression and fatigue

Cognitive problems are a significant, persistent concern for patients undergoing hematopoietic stem cell transplant (HSCT). Sleep is important for many cognitive tasks; however, the relationship between sleep and cognitive problems for HSCT patients is unknown. This study examined the relationship between sleep and cognitive problems for HSCT patients from pre to post transplant. Patients undergoing HSCT (N=138) completed questionnaires at pre-transplant and during the 12 months following transplant. Questionnaires assessed sleep and cognitive problems as well as commonly co-occurring symptoms: depressive symptoms, fatigue and pain. Post hoc analyses examined the relationship of specific sleep problems with cognitive problems. Sleep problems covaried with cognitive problems even after controlling for depressive symptoms, fatigue and pain. Depressive symptoms and fatigue were also uniquely related to cognitive problems. Post hoc analyses suggest that sleep somnolence, shortness of breath, snoring and perceptions of inadequate sleep may contribute to the association found between sleep and cognitive problems. Findings suggest that sleep problems are associated with and may contribute to cognitive problems for HSCT patients. However, sleep problems are rarely screened for or discussed during clinic visits. Assessing and treating specific sleep problems in addition to depressive symptoms and fatigue may have implications for improving cognitive problems for HSCT patients.

The Quest for Mindful Sleep: A Critical Synthesis of the Impact of Mindfulness-Based Interventions for Insomnia

Mindfulness-Based Interventions (MBIs) for insomnia and sleep disturbances are receiving increasing clinical and research attention. This paper provides a critical appraisal of this growing area investigating the application of MBIs for people with insomnia and sleep disturbance. First, we discuss the theoretical justification for how mindfulness meditation practice may affect sleep processes. Second, we provide a focused review of literature published between January 1, 2012 and April 1, 2016 examining the impact of MBIs on sleep, broken down by whether insomnia or sleep disturbance was a primary or secondary outcome. Recommendations for future research are discussed.

The Value of Patient Reported Outcomes and Other Patient-Generated Health Data in Clinical Hematology

With cures and long-term survival rates increasing in hematologic malignancies, increased focus has been placed on gaining a better understanding of the patient experience from disease and treatment effects. This has been the basis for the utilization of patient reported outcomes (PRO) and other patient-generated health data (PGHD) in efforts to improve long-term health-related quality of life (HRQOL). This review will summarize the impact PROs have had on the evolving standard of care for patients with hematologic malignant conditions and will conclude with a template for the integration of PRO and PGHD to enhance the patient experience, using stem cell transplantation as an example.

Emerging uses of patient generated health data in clinical research

Recent advancements in consumer directed personal computing technology have led to the generation of biomedically-relevant data streams with potential health applications. This has catalyzed international interest in Patient Generated Health Data (PGHD), defined as "health-related data - including health history, symptoms, biometric data, treatment history, lifestyle choices, and other information-created, recorded, gathered, or inferred by or from patients or their designees (i.e. care partners or those who assist them) to help address a health concern."(Shapiro et al., 2012) PGHD offers several opportunities to improve the efficiency and output of clinical trials, particularly within oncology. These range from using PGHD to understand mechanisms of action of therapeutic strategies, to understanding and predicting treatment-related toxicity, to designing interventions to improve adherence and clinical outcomes. To facilitate the optimal use of PGHD, methodological research around considerations related to feasibility, validation, measure selection, and modeling of PGHD streams is needed. With successful integration, PGHD can catalyze the application of "big data" to cancer clinical research, creating both "n of 1" and population-level observations, and generating new insights into the nature of health and disease.

National Institutes of Health Consensus Development Project on Criteria for Clinical Trials in Chronic Graft-versus-Host Disease: V. The 2014 Ancillary Therapy and Supportive Care Working Group Report

The 2006 National Institutes of Health (NIH) Consensus paper presented recommendations by the Ancillary Therapy and Supportive Care Working Group to support clinical research trials in chronic graft-versus-host disease (GVHD). Topics covered in that inaugural effort included the prevention and management of infections and common complications of chronic GVHD, as well as recommendations for patient education and appropriate follow-up. Given the new literature that has emerged during the past 8 years, we made further organ-specific refinements to these guidelines. Minimum frequencies are suggested for monitoring key parameters relevant to chronic GVHD during systemic immunosuppressive therapy and, thereafter, referral to existing late effects consensus guidelines is advised. Using the framework of the prior consensus, the 2014 NIH recommendations are organized by organ or other relevant systems and graded according to the strength and quality of supporting evidence.
