Trends in Volumes and Survival After Hematopoietic Cell Transplantation in Racial/Ethnic Minorities.

There has been an increase in volume as well as improvement in overall survival (OS) after hematopoietic cell transplantation (HCT) for hematologic disorders. It is unknown if these changes have impacted racial/ethnic minorities equally. In this observational study from Center for International Blood and Marrow Transplant Research of 79,904 autologous (auto) and 65,662 allogeneic (allo) HCTs, we examined the volume and rates of change of auto HCT and allo HCT over time and trends in OS in 4 racial/ethnic groups: Non-Hispanic Whites (NHWs), Non-Hispanic African Americans (NHAAs), Hispanics across five 2-year cohorts from 2009 to 2018. Rates of change were compared using Poisson model. Adjusted and unadjusted Cox proportional hazards models examined trends in mortality in the 4 racial/ethnic groups over 5 study time periods. The rates of increase in volume were significantly higher for Hispanics and NHAAs vs. NHW for both autoHCT and alloHCT. Adjusted overall mortality after autoHCT was comparable across all racial/ethnic groups. NHAA adults (HR 1.13; 95% CI 1.04-1.22; p=0.004) and pediatric patients (HR 1.62; 95% CI 1.3-2.03; p<0.001 had a higher risk of mortality after alloHCT compared to NHWs. Improvement in OS over time was seen in all 4 groups after both autoHCT and alloHCT.Our study shows the rate of change for the use of autoHCT and alloHCT is higher in NHAAs and Hispanics compared to NHWs. Survival after autoHCT and alloHCT improved over time, however NHAAs have worse OS after alloHCT which has persisted. Continued efforts are needed to mitigate disparities for patients requiring alloHCT.

Experiences of racial discrimination and adverse gene expression among black individuals in a level 1 trauma center sample.

Up to 40 % of individuals who sustain traumatic injuries are at risk for posttraumatic stress disorder (PTSD) and the conditional risk for developing PTSD is even higher for Black individuals. Exposure to racial discrimination, including at both interpersonal and structural levels, helps explain this health inequity. Yet, the relationship between racial discrimination and biological processes in the context of traumatic injury has yet to be fully explored. The current study examined whether racial discrimination is associated with a cumulative measure of biological stress, the gene expression profile conserved transcriptional response to adversity (CTRA), in Black trauma survivors. Two-weeks (T1) and six-months (T2) post-injury, Black participants (N = 94) provided a blood specimen and completed assessments of lifetime racial discrimination and PTSD symptoms. Mixed effect linear models evaluated the relationship between change in CTRA gene expression and racial discrimination while adjusting for age, gender, body mass index (BMI), smoking history, heavy alcohol use history, and trauma-related variables (mechanism of injury, lifetime trauma). Results revealed that for individuals exposed to higher levels of lifetime racial discrimination, CTRA significantly increased between T1 and T2. Conversely, CTRA did not increase significantly over time in individuals exposed to lower levels of lifetime racial discrimination. Thus, racial discrimination appeared to lead to a more sensitized biological profile which was further amplified by the effects of a recent traumatic injury. These findings replicate and extend previous research elucidating the processes by which racial discrimination targets biological systems.

Unfavorable transcriptome profiles and social disadvantage in hematopoietic cell transplantation: a CIBMTR analysis.

Patient-reported outcomes (PROs) capture subjective social determinants of health (SDOHs), which can affect health outcomes through the stress response pathway. The conserved transcriptional response to adversity (CTRA) is a stress-mediated proinflammatory transcriptomic pattern that has been linked to adverse hematopoietic cell transplant (HCT) outcomes. This study examined the association of pretransplant CTRA with patient-reported SDOHs in allogeneic HCT recipients. In this cross-sectional study, pre-HCT SDOH-related PROs included the 36-Item Short Form Health Survey and the Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT). CTRA was assessed by RNA sequencing of whole blood specimens, with mixed effects linear regression models relating CTRA expression to PRO scores while controlling for age, sex, race, disease, and performance status. Among 121 patients, the median age was 54 years, 42% were female, and 91% were White. CTRA was elevated in participants reporting lower scores on the FACT-BMT (P = .003), including the general (P = .003) and BMT-specific (P = .014) components. Effects were driven by the social well-being domain (P = .0001). This corresponded to an 8% to 15% difference in CTRA RNA expression across a 4 standard deviation range in patient-reported SDOHs. Ancillary bioinformatics analyses confirmed the association of well-being with reduced proinflammatory transcription pathway activity [cyclic AMP response element-binding protein, (CREB), NF-κB, and activating protein-1 (AP-1)]. In conclusion, HCT-treated patients who experience unfavorable social conditions show elevated CTRA expression in pretransplant blood samples. These data highlight the biologic sequelae of social well-being and community context and suggest a potential molecular mechanism for the impact of social gradients in HCT outcomes. Targeting this pathway could optimize outcomes in this high-risk population.

Racial and Socioeconomic Disparities in Long-Term Outcomes in ≥1 Year Allogeneic Hematopoietic Cell Transplantation Survivors: A CIBMTR Analysis.

Racial/ethnic minorities have demonstrated worse survival after allogeneic hematopoietic cell transplantation (HCT) compared to whites. Whether the racial disparity in HCT outcomes persists in long-term survivors and possibly may be even exacerbated in this population, which frequently transitions back from the transplant center to their local healthcare providers, is unknown. In the current study, we compared long-term outcomes among 1-year allogeneic HCT survivors by race/ethnicity and socioeconomic status (SES). The Center for International Blood and Marrow Transplant Research database was used to identify 5473 patients with acute myeloid leukemia, acute lymphocytic leukemia, chronic myeloid leukemia, or myelodysplastic syndromes who underwent their first allogeneic HCT between 2007 and 2017 and were alive and in remission for at least 1 year after transplantation. The study was restricted to patients who underwent HCT in the United States. SES was defined using patient neighborhood poverty level estimated from the recipient's ZIP code of residence; a ZIP code with ≥20% of persons below the federal poverty level was considered a high poverty area. The primary outcome was to evaluate the associations of race/ethnicity and neighborhood poverty level with overall survival (OS), relapse, and nonrelapse mortality (NRM). Cox regression models were used to determine associations of ethnicity/race and SES with OS, relapse, and NRM. Standardized mortality ratios were calculated to compare mortality rates of the study patients and their general population peers matched on race/ethnicity, age, and sex. The study cohort was predominately non-Hispanic white (n = 4385) and also included non-Hispanic black (n = 338), Hispanic (n = 516), and Asian (n = 234) patients. Overall, 729 patients (13%) resided in high-poverty areas. Significantly larger proportions of non-Hispanic black (37%) and Hispanic (26%) patients lived in high-poverty areas compared to non-Hispanic whites (10%) and Asians (10%) (P < .01). Multivariable analysis revealed no significant associations between OS, PFS, relapse, or NRM and race/ethnicity or poverty level when adjusted for patient-, disease- and transplantation-related covariates. Our retrospective cohort registry study shows that among adult allogeneic HCT recipients who survived at least 1 year in remission, there were no associations between race/ethnicity, neighborhood poverty level, and long-term outcomes.

Prevalence of Sleep Aid Medication Use in Patients Receiving a Hematopoietic Cell Transplant on an Inpatient Unit.

BACKGROUND AND OBJECTIVES: There is a lack of research regarding the use of sleep aids after hematopoietic stem cell transplantation (HCT). We describe the prevalence of sleep aid administration in the HCT unit and identify associations with patient or clinical characteristics. PATIENTS AND METHODS: In this retrospective analysis of sequential inpatient HCTs from July 1 to December 31, 2016 we describe whether and when patients were prescribed sleep aid medications. Chi-square tests determined significant differences between patient characteristics, sleep aid prescription, and time of prescription. RESULTS: Of the 225 patients identified, 193 (86%) were prescribed sleep aids. Significantly more women received prescriptions for sleep aids (90.4%) than men (81%; P = .047). One hundred patients (44%) received prescriptions exclusively while in the hospital. CONCLUSION: Findings show a high prevalence of sleep medication use in patients undergoing inpatient HCT, primarily during hospitalization. Future efforts toward standardized recommendations to optimize peri-transplant sleep would help clinicians and patients.

Inflammatory cytokines and depression symptoms following hematopoietic cell transplantation.

Increased synthesis and release of inflammatory signalling proteins is common among individuals with hematologic malignancies undergoing hematopoietic cell transplantation (HCT) due to intensive conditioning regimens and complications such as graft-versus-host-disease and infections. Prior research indicates that inflammatory responses can activate central nervous system pathways that evoke changes in mood. This study examined relationships between markers of inflammatory activity and depression symptoms following HCT. Individuals undergoing allogeneic (n = 84) and autologous (n = 155) HCT completed measures of depression symptoms pre-HCT and 1, 3, and 6 months post-HCT. Proinflammatory (IL-6, TNF-α) and regulatory (IL-10) cytokines were assessed by ELISA in peripheral blood plasma. Mixed-effects linear regression models indicated that patients with elevated IL-6 and IL-10 reported more severe depression symptoms at the post-HCT assessments. These findings were replicated when examining both allogeneic and autologous samples. Follow-up analyses clarified that relationships were strongest for neurovegetative, rather than cognitive or affective, symptoms of depression. These findings suggest that anti-inflammatory therapeutics targeting an inflammatory mediator of depression could improve quality of life of HCT recipients.

Mobile health (mHealth) interventions in prostate cancer survivorship: a scoping review.

PURPOSE: This scoping review explores the application of mHealth technology in prostate cancer (CaP) management along the survivorship continuum. METHODS: The scoping review was conducted using the five-step framework developed by Arksey and O'Malley. Using predefined criteria, we screened citations from Embase, EBSCOHost, Cochrane Library, PubMed, ProQuest, SCOPUS, and Web of Science for primary studies published before December 2021. We selected studies that explored the application of mHealth technology in CaP management and survivorship. Evidence from 14 eligible studies was summarized using narrative synthesis. RESULTS: Fourteen studies published between 2015 and 2021 were included. Ten mHealth apps were identified with only one still in use. Most apps were explored for their supportive care roles during radiotherapy (n = 9) and androgen deprivation therapy (ADT) (n = 1) treatment, mainly to assess outcomes (n = 1) and manage patient-reported symptoms (n = 5). One study deployed mHealth to facilitate recovery after surgery. Very few studies (n = 3) applied mHealth for lifestyle management (i.e., physical activity). Barriers to app usage included connectivity issues, end-user familiarity with the app, login hurdles, and time constraints. Facilitators of app usage included apps being downloaded for participants, devices provided for participants, and the ability to connect with providers through the platform. CONCLUSIONS AND IMPLICATIONS FOR CANCER SURVIVORS: The improving survival rates from CaP suggest that men are now living longer with unfavorable treatment side effects such as reduced sexual functioning, pain, and fatigue. Hence, mHealth represents new hope in men's illness trajectory. However, current application in patients' care pathways remains poor, particularly in the active phase of CaP management. Efforts must be accelerated to explore individual and healthcare-level drivers of mHealth use. The feasibility and descriptive nature of current studies point to a lack of attention to actual implementation and scale-up issues in research considering mHealth application in CaP, hence accounting partly for the gap in research/practice.

Targeting the ß2 -adrenergic receptor increases chemosensitivity in multiple myeloma by induction of apoptosis and modulating cancer cell metabolism.

While multi-drug combinations and continuous treatment have become standard for multiple myeloma, the disease remains incurable. Repurposing drugs that are currently used for other indications could provide a novel approach to improve the therapeutic efficacy of standard multiple myeloma treatments. Here, we assessed the anti-tumor effects of cardiac drugs called ß-blockers as a single agent and in combination with commonly used anti-myeloma therapies. Expression of the ß2 -adrenergic receptor correlated with poor survival outcomes in patients with multiple myeloma. Targeting the ß2 -adrenergic receptor (ß2 AR) using either selective or non-selective ß-blockers reduced multiple myeloma cell viability, and induced apoptosis and autophagy. Blockade of the ß2 AR modulated cancer cell metabolism by reducing the mitochondrial respiration as well as the glycolytic activity. These effects were not observed by blockade of ß1 -adrenergic receptors. Combining ß2 AR blockade with the chemotherapy drug melphalan or the proteasome inhibitor bortezomib significantly increased apoptosis in multiple myeloma cells. These data identify the therapeutic potential of ß2 AR-blockers as a complementary or additive approach in multiple myeloma treatment and support the future clinical evaluation of non-selective ß-blockers in a randomized controlled trial. © 2022 The Authors.

Abrupt onset of severe parkinsonism in a patient with metastatic gastrointestinal stromal tumor receiving treatment with avapritinib: A case report.

Gastrointestinal stromal tumors (GISTs) are tumors of the digestive tract. To date, there have been no neurological paraneoplastic syndromes or symptoms associated with metastatic GISTs. Tyrosine kinase inhibitors (TKIs) are the typical class of agents used in management of this malignancy. Avapritinib, a new TKI, has been associated with myriad neurological adverse events with fairly rapid resolution in clinical trials. Herein, we present the case of a patient with metastatic GIST who, after starting treatment with avapritinib, developed rapidly progressive and persisting severe neuropsychiatric symptoms, including profound parkinsonism and encephalopathy, while concurrently receiving therapy with the antipsychotic olanzapine. We posit that the patient could be conceptualized as having a relative vulnerability to medication effects in the setting of metastatic GIST - possibly driven by an immune-mediated process - and that the addition of avapritinib triggered an overtly evident, clinically significant cascade of neurological deterioration.

The Impact of Beta-Blocker Use at the Time of Hematopoietic Cell Transplantation on the Development of Acute and Chronic Graft-Versus-Host Disease.

Sympathetic nervous system activation plays a role in the development of acute and chronic graft-versus-host disease (GVHD) following allogeneic hematopoietic cell transplantation (HCT). The primary objective was to compare the cause-specific hazard of grade II-IV and III-IV acute GVHD (aGVHD) and chronic GVHD (cGVHD) in the context of ß-blocker use and type (selective vs. non-selective). Secondary objectives included overall survival (OS), relapse-free survival (RFS), and cumulative incidence of relapse, non-relapse mortality (NRM), and grade II-IV and III-IV aGVHD and cGVHD. The current study included 151 patients ages 18 and older diagnosed with hematological malignancies who underwent reduced intensity conditioning allogeneic HCT from HLA matched related or unrelated donors between January 2014 and 2017. 31 patients were on a ß-blocker of which 71% were on a selective ß-blocker. The incidence of aGVHD was not different among groups. Results show a non-significant trend in the association between ß-blocker use and reduction in the risk of developing cGVHD (cause-specific hazard ratio 0.49, p = 0.060), with no negative impact on survival or relapse. The current data are supportive of a potential ß-adrenergic influence on the pathogenesis of GVHD, consistent with the inflammatory etiology of GVHD and the anti-inflammatory effects of ß-adrenergic antagonists.

Biobehavioral Implications of Chimeric Antigen Receptor T-cell Therapy: Current State and Future Directions.

Chimeric antigen receptor (CAR) T-cell therapy has demonstrated remarkable clinical responses in hematologic malignancies. Recent advances in CAR T-cell therapy have expanded its application into other populations including older patients and those with central nervous system and solid tumors. Although its clinical efficacy has been excellent for some malignancies, CAR T-cell therapy is associated with severe and even life-threatening immune-mediated toxicities, including cytokine release syndrome and neurotoxicity. There is a strong body of scientific evidence highlighting the connection between immune activation and neurocognitive and psychological phenomena. To date, there has been limited investigation into this relationship in the context of immunotherapy. In this review, we present a biobehavioral framework to inform current and future cellular therapy research and contribute to improving the multidimensional outcomes of patients receiving CAR T-cell therapy.

New-onset hallucinations with amiodarone: a case report.

BACKGROUND: Amiodarone is a commonly used antiarrhythmic for the treatment of atrial fibrillation with a unique pharmacokinetic profile. While general side effects can be frequently associated with amiodarone, psychiatric adverse reactions to this medication are uncommon. The relationship between amiodarone and hallucinations independent of delirium has been rarely reported in the literature. CASE PRESENTATION: We report the case of a 63-year-old female with a history of estrogen and progesterone receptor positive invasive ductal carcinoma with osseous metastases to the ribs and skull, major depressive disorder, and unspecified anxiety. She was diagnosed with invasive ductal carcinoma 12 years prior and underwent a lumpectomy with axillary lymph node dissection and radiation, currently maintained on anastrozole and trastuzumab for the past 11 years. Her symptoms of major depressive disorder and anxiety have remained in remission on a regimen of bupropion extended release, duloxetine, and trazodone without recent dose changes. This patient presented to the emergency department with dyspnea and was admitted to the general medical floor with new-onset atrial fibrillation. She was subsequently started on amiodarone for rhythm control. Shortly after its initiation, the patient developed new onset auditory and visual hallucinations with an unremarkable extensive medical evaluation. Auditory hallucinations consisted of music and unintelligible conversations, while visual hallucinations were of a family member crying on the floor and a man carrying a gun. The differential diagnoses included depression with psychotic features, delirium, and amiodarone-induced hallucinations. Given the lack of current depressive symptoms, absence of altered cognition, and the temporal relationship between the initiation of amiodarone and the onset of hallucinations, amiodarone was suspected to be probable etiology of her hallucinations. For this reason, amiodarone was replaced with dronedarone. Visual and auditory hallucinations ceased within less than 3 days after the discontinuation of amiodarone. CONCLUSIONS: Psychiatric adverse events from amiodarone are uncommon, and associated isolated hallucinations have only been rarely reported in the literature. While the risk of visual and auditory hallucinations appears to be low with amiodarone initiation, clinicians should be aware of this potential side effect.

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.

The effect of tocilizumab on patient reported outcomes and inflammatory biomarkers in hematopoietic cell transplantation.

Inflammatory physiology has been linked to behavioral and emotional symptoms in a variety of contexts and experimental paradigms. Hematopoietic cell transplantation (HCT) represents an intersection of significant immune dysregulation and psychosocial stress, and this biobehavioral relationship can influence important clinical outcomes. For those undergoing HCT with inflammation-related neuropsychiatric symptoms, using targeted agents such as the IL-6 receptor antagonist tocilizumab may be an effective therapeutic approach. We conducted an observational cohort study to explore patient reported outcomes (PROs) and inflammatory biomarkers among allogeneic HCT recipients who received tocilizumab compared to those who did not. Individuals on a larger trial of tocilizumab for prevention of graft-versus-host disease received a single dose of tocilizumab 24 h prior to stem cell infusion. Measures of anxiety, depression, pain, fatigue, and sleep quality and parallel blood samples for inflammatory cytokines were collected from participants and an analogous comparison cohort at baseline and Day 28 after stem cell infusion. Demographic and medical characteristics were reported; an analysis of covariance regression model was fitted to evaluate differences in PROs and distance correlation t-tests assessed for associations between biomarkers and PRO measures. For n = 18 tocilizumab-treated and n = 22 comparison patients, there were no significant differences between patient demographics, but the tocilizumab cohort had a different distribution of primary diagnoses (p = 0.009) with more patients with leukemias and a higher proportion of patients in their first remission (64% vs 28%, p = 0.024). Depression was higher at Day 28 compared to baseline in both groups (comparison group: +5.1 [95% CI 0.14-10, p = 0.045], tocilizumab: +8.6 [95% CI 2.3-15, p = 0.011]), though the difference between groups did not reach statistical significance. The tocilizumab group had significantly increased circulating IL-6 and decreased CRP at Day 28 (all p < 0.05). There was an association between collective baseline biomarkers and PROs (distance correlation dCor = 0.110, p = 0.005), but this same association was not present at Day 28 (dCor = -0.001, p = 0.5). In univariate analyses, a 10-fold increase in plasma IL-6 was associated with a 3.6-point higher depression score (95% CI 1.0-6.2, p = 0.008). In this exploratory analysis of PROs and inflammatory biomarkers in patients undergoing HCT, tocilizumab was not associated with favorable patient-reported symptom profiles. This finding is aligned with our prior work in the HCT population but diverges from hypothesized therapeutic effects of tocilizumab on depressive symptoms, thus highlighting the need for larger prospective translational studies in biobehavioral HCT research.

Patient-reported outcomes and neurotoxicity markers in patients treated with bispecific LV20.19 CAR T cell therapy.

Background: With the rising number of chimeric antigen receptor (CAR) T cell treated patients, it is increasingly important to understand the treatment's impact on patient-reported outcomes (PROs) and, ideally, identify biomarkers of central nervous system (CNS) adverse effects. Methods: The purpose of this exploratory study was to assess short-term PROs and serum kynurenine metabolites for associated neurotoxicity among patients treated in an anti-CD20, anti-CD19 (LV20.19) CAR T cell phase I clinical trial (NCT03019055). Fifteen CAR T treated patients from the parent trial provided serum samples and self-report surveys 15 days before and 14, 28, and 90 days after treatment. Results: Blood kynurenine concentrations increased over time in patients with evidence of neurotoxicity (p = 0.004) and were increased in self-reported depression (r = 0.52, p = 0.002). Depression improved after CAR T infusion (p = 0.035). Elevated 3-hydroxyanthranilic acid (3HAA) concentrations prior to cell infusion were also predictive of neurotoxicity onset (p = 0.031), suggesting it is a biomarker of neurotoxicity following CAR T cell therapy. Conclusions: Elevated levels of kynurenine pathway metabolites among CAR T cell recipients are associated with depressed mood and neurotoxicity. Findings from this exploratory study are preliminary and warrant validation in a larger cohort.

This study examined the impact of chimeric antigen receptor (CAR) T cell therapy­a therapy that gets immune cells to fight cancer by changing them in the lab to find and destroy cancer cells­on blood markers associated with depression, anxiety, pain, fatigue, and poor sleep. Fifteen CAR T cell patients provided blood samples and completed surveys before and three timepoints after treatment. We found that the amount of kynurenine, a normal blood constituent, and related molecules was higher in patients who experienced significant CAR T cell side effects on the brain and in patients reporting more depression. These results identify the excessive elevation of blood constituents related to the mood that may also be associated with depression and brain dysfunction following CAR T. These blood constituents could potentially be used as markers and targeted with interventions to prevent brain dysfunction.

Biobehavioral Pathways and Cancer Progression: Insights for Improving Well-Being and Cancer Outcomes.

The relationship between psychosocial factors and cancer has intrigued people for centuries. In the last several decades there has been an expansion of mechanistic research that has revealed insights regarding how stress activates neuroendocrine stress-response systems to impact cancer progression. Here, we review emerging mechanistic findings on key pathways implicated in the effect of stress on cancer progression, including the cellular immune response, inflammation, angiogenesis, and metastasis, with a primary focus on the mediating role of the sympathetic nervous system. We discuss converging findings from preclinical and clinical cancer research that describe these pathways and research that reveals how these stress pathways may be targeted via pharmacological and mind-body based interventions. While further research is required, the body of work reviewed here highlights the need for and feasibility of an integrated approach to target stress pathways in cancer patients to achieve comprehensive cancer treatment.

Perceptions and Experiences of Hematopoietic Cell Transplantation Patients During the COVID-19 Pandemic.

OBJECTIVES: Since March 2020, the severe acute respiratory syndrome coronavirus-2 pandemic has affected the global community, but poses unique challenges for individuals with cancer. Patients diagnosed with hematologic malignancies undergo aggressive therapies followed by hematopoietic cell transplantation (HCT) as a potential curative treatment. HCT recipients can be immunocompromised for extended periods of time, and even pre-pandemic, transplant patients reported depression and anxiety due to restrictions and infection prevention measures they had to adhere to as part of transplant precautions. This study aimed to understand psychological distress and capture perspectives on coping strategies and access to healthcare in the HCT population during the COVID-19 pandemic. DATA SOURCES: Adult patients who received a transplant or were awaiting transplant and had a scheduled appointment at the transplant clinic were eligible to participate in this cross-sectional study. Participants completed an online survey that included questionnaires, clinical data and demographic information. CONCLUSION: Fifty-four participants completed the survey. HCT participants reported relatively high psychological distress during the initial phase of the COVID-19 pandemic, but indicated use of healthy coping mechanisms to deal with stress. IMPLICATION FOR NURSING PRACTICE: Study data informs healthcare providers that psychological distress and mental health warrants increased attention during periods of heightened stress. Education and resources on healthy, beneficial coping strategies should be provided to support HCT patients. Nurses and advanced nurse practitioners are well poised to interact with HCT patients and provide necessary support or appropriate referral during routine clinical interactions, preparing patients for prolonged effects of the pandemic and similar future events.

Rap1A, Rap1B, and ß-Adrenergic Signaling in Autologous HCT: A Randomized Controlled Trial of Propranolol.

Successful hematopoietic cell transplantation (HCT) depends on rapid engraftment of the progenitor and stem cells that will reestablish hematopoiesis. Rap1A and Rap1B are two closely related small GTPases that may affect platelet and neutrophil engraftment during HCT through their roles in cell adhesion and migration. ß-adrenergic signaling may regulate the participation of Rap1A and Rap1B in engraftment through their inhibition or activation. We conducted a correlative study of a randomized controlled trial evaluating the effects of the nonselective ß-antagonist propranolol on expression and prenylation of Rap1A and Rap1B during neutrophil and platelet engraftment in 25 individuals receiving an autologous HCT for multiple myeloma. Propranolol was administered for 1 week prior to and 4 weeks following HCT. Blood was collected 7 days (baseline) and 2 days (Day -2) before HCT, and 28 days after HCT (Day +28). Circulating polymorphonuclear cells (PMNC) were isolated and analyzed via immunoblotting to determine levels of prenylated and total Rap1A versus Rap1B. Twelve participants were randomized to the intervention and 13 to the control. Rap1A expression significantly correlated with Rap1B expression. Rap1B expression significantly correlated with slower platelet engraftment; however, this association was not observed in the propranolol-treated group. There were no significant associations between neutrophil engraftment and Rap1A or Rap1B expression. Post hoc exploratory analyses did not reveal an association between social health variables and Rap1A or Rap1B expression. This study identifies a greater regulatory role for Rap1B than Rap1A in platelet engraftment and suggests a possible role for ß-adrenergic signaling in modulating Rap1B function during HCT.
