Association between adverse childhood experiences and health related quality of life in adult cancer survivors in the United States.

PURPOSE: The impact of adverse childhood experiences (ACEs) on health-related quality of life (HRQOL) is increasingly recognized, however, this has not been studied in cancer survivors in the United States. This study investigates if ACEs are associated with HRQOL in cancer survivors. METHODS: We conducted a cross-sectional analysis of the 2020 Behavioral Risk Factor Surveillance System from states that administered ACEs and Cancer Survivorship modules. Eligibility criteria included being a cancer survivor and not currently receiving cancer treatment. Primary exposure was number of ACEs (categorized as 0, 1-2, 3, or ≥ 4). Primary outcomes were self-reported measures of HRQOL including worse overall health and ≥ 14 unhealthy days (mentally or physically) per month. Mantel-Haenszel stratified analyses were performed and prevalence ratios were adjusted for age. RESULTS: Of 5,780 participants, 62.0% were female and 67.8% were ≥ 65 years. Prevalence of worse overall health was 22.5% for individuals with no ACEs compared to 30.2% for 2-3 ACEs (aPR = 1.4, 95% CI 1.2, 1.5) and 38.5% for ≥ 4 ACEs (aPR = 1.7, 95% CI 1.5, 2.0). Prevalence of ≥ 14 unhealthy days was 18.1% with no ACEs compared to 21.0% for 1 ACE (aPR = 1.3, 95% CI 1, 1.3), 29.0% for 2-3 ACEs (aPR = 1.6, 95% CI 1.4, 1.8), and 44.8% for ≥ 4 ACEs (aPR = 2.2, 95% CI 2.0, 2.5). CONCLUSIONS: Our study provides novel evidence of the association of multiple ACEs with higher prevalence of poor HRQOL in cancer survivors. IMPLICATIONS FOR CANCER SURVIVORS: Screening for ACEs is warranted in all patients to guide targeted interventions to improve HRQOL and mitigate the impact of ACEs on HRQoL in cancer survivors.

The impact of low-mode symmetry on inertial fusion energy output in the burning plasma state.

Indirect Drive Inertial Confinement Fusion Experiments on the National Ignition Facility (NIF) have achieved a burning plasma state with neutron yields exceeding 170 kJ, roughly 3 times the prior record and a necessary stage for igniting plasmas. The results are achieved despite multiple sources of degradations that lead to high variability in performance. Results shown here, for the first time, include an empirical correction factor for mode-2 asymmetry in the burning plasma regime in addition to previously determined corrections for radiative mix and mode-1. Analysis shows that including these three corrections alone accounts for the measured fusion performance variability in the two highest performing experimental campaigns on the NIF to within error. Here we quantify the performance sensitivity to mode-2 symmetry in the burning plasma regime and apply the results, in the form of an empirical correction to a 1D performance model. Furthermore, we find the sensitivity to mode-2 determined through a series of integrated 2D radiation hydrodynamic simulations to be consistent with the experimentally determined sensitivity only when including alpha-heating.

Design of the first fusion experiment to achieve target energy gain G>1.

In this work we present the design of the first controlled fusion laboratory experiment to reach target gain G>1 N221204 (5 December 2022) [Phys. Rev. Lett. 132, 065102 (2024)10.1103/PhysRevLett.132.065102], performed at the National Ignition Facility, where the fusion energy produced (3.15 MJ) exceeded the amount of laser energy required to drive the target (2.05 MJ). Following the demonstration of ignition according to the Lawson criterion N210808, experiments were impacted by nonideal experimental fielding conditions, such as increased (known) target defects that seeded hydrodynamic instabilities or unintentional low-mode asymmetries from nonuniformities in the target or laser delivery, which led to reduced fusion yields less than 1 MJ. This Letter details design changes, including using an extended higher-energy laser pulse to drive a thicker high-density carbon (also known as diamond) capsule, that led to increased fusion energy output compared to N210808 as well as improved robustness for achieving high fusion energies (greater than 1 MJ) in the presence of significant low-mode asymmetries. For this design, the burnup fraction of the deuterium and tritium (DT) fuel was increased (approximately 4% fuel burnup and a target gain of approximately 1.5 compared to approximately 2% fuel burnup and target gain approximately 0.7 for N210808) as a result of increased total (DT plus capsule) areal density at maximum compression compared to N210808. Radiation-hydrodynamic simulations of this design predicted achieving target gain greater than 1 and also the magnitude of increase in fusion energy produced compared to N210808. The plasma conditions and hotspot power balance (fusion power produced vs input power and power losses) using these simulations are presented. Since the drafting of this manuscript, the results of this paper have been replicated and exceeded (N230729) in this design, together with a higher-quality diamond capsule, setting a new record of approximately 3.88MJ of fusion energy and fusion energy target gain of approximately 1.9.

Observations and properties of the first laboratory fusion experiment to exceed a target gain of unity.

An indirect-drive inertial fusion experiment on the National Ignition Facility was driven using 2.05 MJ of laser light at a wavelength of 351 nm and produced 3.1±0.16 MJ of total fusion yield, producing a target gain G=1.5±0.1 exceeding unity for the first time in a laboratory experiment [Phys. Rev. E 109, 025204 (2024)10.1103/PhysRevE.109.025204]. Herein we describe the experimental evidence for the increased drive on the capsule using additional laser energy and control over known degradation mechanisms, which are critical to achieving high performance. Improved fuel compression relative to previous megajoule-yield experiments is observed. Novel signatures of the ignition and burn propagation to high yield can now be studied in the laboratory for the first time.

Concurrent use of two dual-combination drenches containing monepantel/abamectin and oxfendazole/levamisole in sheep: effect on marker residues 21 and 28 days after administration.

AIMS: To determine the concentration, in comparison with the maximum residue limit (MRL), of anthelmintic marker residues in the target tissues (liver and fat) of sheep treated concurrently with two oral drenches, one containing monepantel and abamectin and the other oxfendazole and levamisole. METHODS: On day 0 of the study, 12 sheep (six male and six female; 8-9-months old) were dosed according to individual body weight determined the day prior. Zolvix Plus (dual-active oral drench containing 25 g/L monepantel and 2 g/L abamectin) was administered to all animals prior to administration of Scanda (dual-active oral drench containing 80 g/L levamisole hydrochloride and 45.3 g/L oxfendazole). Six sheep (three male and three female) were slaughtered 21 and 28 days after treatment and renal fat and liver samples were collected.Using validated methods, analyses for monepantel sulfone, abamectin, levamisole and oxfendazole (expressed as total fenbendazole sulfone following conversion of the combined concentrations of oxfendazole, fenbendazole and fenbendazole sulfone) were performed on liver samples while renal fat specimens were analysed for monepantel sulfone and abamectin residues only. Detected concentrations were compared to the established MRL in sheep for each analyte determined by the Ministry for Primary Industries. RESULTS: All residues detected in samples of liver and fat collected 21 and 28 days after treatment were below the MRL for each analyte. All liver samples collected on day 21 had detectable monepantel sulfone (mean 232 (min 110, max 388) µg/kg) and oxfendazole (mean 98.7 (min 51.3, max 165) µg/kg) residues below the MRL (5,000 and 500 µg/kg, respectively). Monepantel sulfone (mean 644 (min 242, max 1,119) µg/kg; MRL 7,000 µg/kg) residues were detected in 6/6 renal fat samples. Levamisole residues were detected in 3/6 livers (mean 40.0 (min 14.3, max 78.3) µg/kg; MRL 100 µg/kg), and abamectin residues in 1/6 livers (0.795 µg/kg; MRL 25 µg/kg) and 2/6 fat samples, (mean 0.987 (min 0.514, max 1.46) µg/kg; MRL 50 µg/kg) 21 days after treatment. CONCLUSION AND CLINICAL RELEVANCE: These results suggest that concurrent administration of Zolvix Plus and Scanda to sheep is unlikely to result in an extended residue profile for any of the active ingredients, with all analytes measured being under the approved New Zealand MRL 21 days after treatment. This work was not completed in line with guidance for establishing official residue profiles, nor is it sufficient to propose a new withholding period.

International Recommendations for Screening and Preventative Practices for Long-Term Survivors of Transplantation and Cellular Therapy: A 2023 Update.

As hematopoietic cell transplantation (HCT) and cellular therapy expand to new indications and international access improves, the number of HCTs performed annually continues to rise. Parallel improvements in HCT techniques and supportive care entails more patients surviving long term, creating further emphasis on survivorship needs. Survivors are at risk for developing late complications secondary to pretransplantation, peritransplantation, and post-transplantation exposures and other underlying risk factors. Guidelines for screening and preventive practices for HCT survivors were originally published in 2006 and then updated in 2012. An international group of experts was convened to review the contemporary literature and update the recommendations while considering the changing practices of HCT and cellular therapy. This review provides updated pediatric and adult survivorship guidelines for HCT and cellular therapy. The contributory role of chronic graft-versus-host disease (cGVHD) to the development of late effects is discussed, but cGVHD management is not covered in detail. These guidelines emphasize the special needs of patients with distinct underlying HCT indications or comorbidities (eg, hemoglobinopathies, older adults) but do not replace more detailed group-, disease-, or condition-specific guidelines. Although these recommendations should be applicable to the vast majority of HCT recipients, resource constraints may limit their implementation in some settings.

Return to school practices after hematopoietic cell transplantation: a survey of transplant centers in the United States.

To understand transplant center recommendations on return-to-school timing and related support for hematopoietic cell transplant (HCT) survivors, we conducted a two-phase, cross-sectional, web-based survey: In Phase I, medical directors of pediatric HCT centers from the National Marrow Donor Program/ Be The Match Registry were asked regarding the availability of a return to school standardized operating procedure (SOP). In Phase II, HCT physician members of the Pediatric Transplantation and Cellular Therapy Consortium were approached to study inter-physician practice variability regarding return to school post-HCT, factors affecting their decision-making, and support provided by HCT centers for return to school. Out of 46 respondents in Phase I (55% response rate), 28 (61%) reported having a SOP. Wide variations in recommendations were noted in 12 received SOPs. In Phase II, 122 physicians (60 centers) responded (30.6% response rate). The majority (60%) recommended autologous HCT recipients return to school within 6 months post-HCT but 65% recommended allogeneic HCT recipients return to school after 6 months or once off immunosuppression. Our findings indicate a lack of consensus within and across HCT centers regarding recommended return to school timing and underscore need for a guideline to standardize this process to ensure patient safety and re-integration into school.

Ancient and modern DNA track temporal and spatial population dynamics in the European fallow deer since the Eemian interglacial.

Anthropogenic factors have impacted the diversity and evolutionary trajectory of various species. This can be through factors such as pressure on population size or range, habitat fragmentation, or extensive manipulation and translocation. Here we use time-calibrated data to better understand the pattern and processes of evolution in the heavily manipulated European fallow deer (Dama dama). During the Pleistocene, fallow deer had a broad distribution across Europe and were found as far north as Britain during the Eemian interglacial. The last glacial period saw fallow deer retreat to southern refugia and they did not disperse north afterwards. Their recolonisation was mediated by people and, from northern Europe and the British Isles, fallow deer were transported around the world. We use ancient and modern mitochondrial DNA (mtDNA) and mitogenomic data from Eemian Britain to assess the pattern of change in distribution and lineage structure across Europe over time. We find founder effects and mixed lineages in the northern populations, and stability over time for populations in southern Europe. The Eemian sample was most similar to a lineage currently in Italy, suggesting an early establishment of the relevant refuge. We consider the implications for the integration of anthropogenic and natural processes towards a better understanding of the evolution of fallow deer in Europe.

International recommendations for screening and preventative practices for long-term survivors of transplantation and cellular therapy: a 2023 update.

As hematopoietic cell transplantation (HCT) and cellular therapy expand to new indications and international access improves, the volume of HCT performed annually continues to rise. Parallel improvements in HCT techniques and supportive care entails more patients surviving long-term, creating further emphasis on survivorship needs. Survivors are at risk for developing late complications secondary to pre-, peri- and post-transplant exposures and other underlying risk-factors. Guidelines for screening and preventive practices for HCT survivors were originally published in 2006 and updated in 2012. To review contemporary literature and update the recommendations while considering the changing practice of HCT and cellular therapy, an international group of experts was again convened. This review provides updated pediatric and adult survivorship guidelines for HCT and cellular therapy. The contributory role of chronic graft-versus-host disease (cGVHD) to the development of late effects is discussed but cGVHD management is not covered in detail. These guidelines emphasize special needs of patients with distinct underlying HCT indications or comorbidities (e.g., hemoglobinopathies, older adults) but do not replace more detailed group, disease, or condition specific guidelines.

Standardizing Randomized Controlled Trials in Celiac Disease: An International Multidisciplinary Appropriateness Study.

BACKGROUND & AIMS: There is a need to develop safe and effective pharmacologic options for the treatment of celiac disease (CeD); however, consensus on the appropriate design and configuration of randomized controlled trials (RCTs) in this population is lacking. METHODS: A 2-round modified Research and Development/University of California Los Angeles Appropriateness Method study was conducted. Eighteen gastroenterologists (adult and pediatric) and gastrointestinal pathologists voted on statements pertaining to the configuration of CeD RCTs, inclusion and exclusion criteria, gluten challenge, and trial outcomes. Two RCT designs were considered, representing the following distinct clinical scenarios for which pharmacotherapy may be used: trials incorporating a gluten challenge to simulate exposure; and trials evaluating reversal of histologic changes, despite attempted adherence to a gluten-free diet. Each statement was rated as appropriate, uncertain, or inappropriate, using a 9-point Likert scale. RESULTS: For trials evaluating prevention of relapse after gluten challenge, participants adherent to a gluten-free diet for 12 months or more with normal or near-normal-sized villi should be enrolled. Gluten challenge should be FODMAPS (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) free, and efficacy evaluated using histology with a secondary patient-reported outcome measure. For trials evaluating reversal of villus atrophy, the panel voted it appropriate to enroll participants with a baseline villus height to crypt depth ratio ≤2 and measure efficacy using a primary histologic end point. Guidance for measuring histologic, endoscopic, and patient-reported outcomes in adult and pediatric patients with CeD are provided, along with recommendations regarding the merits and limitations of different end points. CONCLUSIONS: We developed standardized recommendations for clinical trial design, eligibility criteria, outcome measures, gluten challenge, and disease evaluations for RCTs in patients with CeD.

Impact of Hematopoietic Cell Transplantation on Cardiovascular Risk Factors and Insulin Sensitivity.

The use of hematopoietic cell transplantation (HCT) for treating malignant conditions in children has increased over the past five decades, leading to a growing population of long-term survivors.This population of childhood HCT survivors faces increased risks of adverse medical effects due to cancer treatments, including adverse cardiovascular disease (CVD) risk factors such as metabolic syndrome, insulin resistance. but the impact of exposure to HCT preparative conditioning regimen has not been clearly delineated. These risk factors, including obesity, dyslipidemia, hypertension, and insulin resistance (IR), are significant contributors to premature cardiovascular disease and represent a leading cause of non-relapse deaths in childhood cancer and HCT survivors. This study aimed to assess the early development of CVD risk factors and their relationship to insulin resistance in a large population of pediatric and young adult HCT survivors of childhood hematologic malignancies. The study compared their cardiovascular risk profiles, insulin resistance (measured by euglycemic hyperinsulinemic clamp studies), and body composition (determined by dual X-ray absorptiometry - DXA) with a cohort of sibling controls. We enrolled 151 HCT recipients (26.36 ±0.90 years at study enrollment; time since HCT of 2.6-31.5 years) and 92 sibling controls to complete at cardiovascular risk assessment including insulin sensitivity by hyperinsulinemic euglycemic clamp, anthropometry, body composition by dual X-ray absorptiometry, blood pressure, and serum biomarkers. We used linear models to test for mean differences in all continuous outcomes between survivors and siblings, accounting for intra-family correlations with generalized estimating equations. Recipients of HCT were found to have lower insulin sensitivity and more likely to have adverse CVD risk factors in comparison to their healthy siblings. Significantly higher percent fat mass and visceral adipose tissue, and significantly lower lean body mass were noted in HCT recipients than sibling controls despite having a similar body mass index between the two groups. Total body irradiation in the conditioning regimen was one of the strongest factors associated with lower insulin sensitivity, dyslipidemia and abnormal body composition leading to sarcopenic obesity. This study reveals that pediatric and young adult HCT survivors are more insulin resistant and have a higher prevalence of adverse cardiovascular risk factors compared to sibling controls. The presence of cardiovascular risk factors at a relatively young age raises concerns about an escalating trajectory of cardiovascular disease in this population. Therefore, regular monitoring of HCT survivors for cardiometabolic risk factors and early intervention will be crucial for preventing cardiovascular-related complications in the future. The findings underscore the importance of survivorship care for pediatric and young adult HCT survivors, with a focus on managing cardiovascular risk factors and promoting a healthy lifestyle to mitigate long-term adverse effects. Early identification and targeted interventions can significantly improve the long-term health outcomes of this vulnerable population, reducing the burden of cardiovascular disease and related complications.

Developmental changes in functional connectivity between the prefrontal cortex and amygdala following fear extinction.

The amygdala and prefrontal cortex (PFC) undergo dramatic changes in structure, function, and regional connectivity in early life, ultimately stabilizing in early adulthood. Pathways between these two structures underlie many forms of emotional learning, including the extinction of conditioned fear. Here we sought to characterize changes in extinction-related medial PFC (mPFC) â†’ amygdala functional connectivity across development that might explain adolescent impairments in extinction. The retrograde tracer Fluorogold was infused into the amygdala of postnatal day (P)22-23 (juvenile), P31-32 (adolescent), or ≥ P69 (adult) rats, which were then exposed to fear conditioning and extinction training. Brains were collected following extinction or context exposure and processed for expression of pMAPK (as a marker of learning-dependent plasticity) in prelimbic (PL) and infralimbic (IL) amygdala-projecting neurons. Consistent with previous findings, amygdala-projecting mPFC neurons were located primarily in layers (L)II/III and V of the mPFC. We noted that mPFC LII/III projected predominantly to the ipsilateral basolateral amygdala, whereas LV projected bilaterally and targeted multiple amygdalar nuclei. Extinction was not associated with changes in extinction-related plasticity in the PL-amygdala pathways in any age group. No changes were seen in LII/III of the IL, but extinction-related plasticity in LV amygdala-projecting IL neurons decreased linearly across development. These findings suggest that extinction-related functional connectivity between the IL and the amygdala undergoes fundamental changes across development that may contribute to alterations in fear suppression across development.

The presence of busulfan metabolites and pharmacometabolomics in plasma drawn immediately before allograft infusion in hematopoietic cell transplant recipients.

Busulfan is hepatically metabolized through glutathione (GSH) conjugation; in vitro, this process depletes hepatocyte GSH stores and generates the cytotoxic metabolite γ-glutamyldehydroalanylglycine, which is too unstable to be quantitated in vivo. We sought to evaluate if pre-graft (i.e., immediately before allograft infusion) concentrations of busulfan metabolites' and of endogenous metabolomic compounds (EMCs) representing the glutathione pathway were associated with clinical outcomes in hematopoietic cell transplant (HCT) recipients receiving busulfan. The clinical outcomes evaluated were relapse, acute graft versus host disease (GVHD), chronic GVHD, non-relapse mortality, and neutrophil nadir. In pre-graft samples obtained from patients immediately before allograft infusion, our objectives were to evaluate for: (1) the presence of busulfan and its metabolites tetrahydrothiophenium ion (THT+), tetrahydrothiophene 1-oxide, sulfolane, and 3-hydroxysulfolane (N = 124); (2) EMCs using a global metabolomics assay (N = 77); and (3) the association of the busulfan metabolites and the EMCs with clinical outcomes. In the pre-graft samples, busulfan and THT+ could not be detected. THT 1-oxide, sulfolane, and 3-hydroxysulfolane were quantitated in 9.6%, 26%, and 58% of pre-graft samples; their concentrations were not associated with clinical outcomes. Four pre-graft EMCs were statistically significantly associated with the neutrophil nadir. The pre-graft EMCs were not associated with the other clinical outcomes. In conclusion, busulfan's metabolites are present in patients' plasma immediately before allograft infusion; the neutrophil nadir is associated with pre-graft EMCs. Future research should investigate the association of clinical outcomes with the concentrations of busulfan's metabolites and EMCs in the pre-graft plasma from allogeneic HCT recipients.

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.

Dynamics and Power Balance of Near Unity Target Gain Inertial Confinement Fusion Implosions.

The change in the power balance, temporal dynamics, emission weighted size, temperature, mass, and areal density of inertially confined fusion plasmas have been quantified for experiments that reach target gains up to 0.72. It is observed that as the target gain rises, increased rates of self-heating initially overcome expansion power losses. This leads to reacting plasmas that reach peak fusion production at later times with increased size, temperature, mass and with lower emission weighted areal densities. Analytic models are consistent with the observations and inferences for how these quantities evolve as the rate of fusion self-heating, fusion yield, and target gain increase. At peak fusion production, it is found that as temperatures and target gains rise, the expansion power loss increases to a near constant ratio of the fusion self-heating power. This is consistent with models that indicate that the expansion losses dominate the dynamics in this regime.

Alemtuzumab and CXCL9 levels predict likelihood of sustained engraftment after reduced-intensity conditioning HCT.

Overall survival after reduced-intensity conditioning (RIC) allogeneic hematopoietic cell transplantation (HCT) using alemtuzumab, fludarabine, and melphalan is associated with high rates of mixed chimerism (MC) and secondary graft failure (GF). We hypothesized that peritransplantation alemtuzumab levels or specific patterns of inflammation would predict these risks. We assessed samples from the Bone Marrow Transplant Clinical Trials Network 1204 (NCT01998633) to study the impact of alemtuzumab levels and cytokine patterns on MC and impending or established secondary GF (defined as donor chimerism <5% after initial engraftment and/or requirement of cellular intervention). Thirty-three patients with hemophagocytic lymphohistiocytosis (n = 25) and other IEIs (n = 8) who underwent HCTs with T-cell-replete grafts were included. Patients with day 0 alemtuzumab levels ≤0.32 µg/mL had a markedly lower incidence of MC, 14.3%, vs 90.9% in patients with levels >0.32 µg/mL (P = .008). Impending or established secondary GF was only observed in patients with day 0 alemtuzumab levels >0.32 µg/mL (P = .08). Unexpectedly, patients with impending or established secondary GF had lower CXCL9 levels. The cumulative incidence of impending or established secondary GF in patients with a day 14+ CXCL9 level ≤2394 pg/mL (day 14+ median) was 73.6% vs 0% in patients with a level >2394 pg/mL (P = .002). CXCL9 levels inversely correlated with alemtuzumab levels. These data suggest a model in which higher levels of alemtuzumab at day 0 deplete donor T cells, inhibit the graft-versus-marrow reaction (thereby suppressing CXCL9 levels), and adversely affect sustained engraftment in the nonmyeloablative HCT setting. This trial was registered at www.clinicaltrials.gov as #NCT01998633.

Patient-Reported Outcomes in Long-Term Survivors of Autologous Hematopoietic Cell Transplantation in Multiple Myeloma.

The overall survival in patients with transplantation-eligible multiple myeloma has tripled over the past 2 decades, leading to a growing population of myeloma survivors. However, there is a paucity of data on health-related quality of life (HRQoL), distress, and health behaviors in long-term myeloma survivors who are in stable remission after autologous hematopoietic cell transplantation (AHCT). In this cross-sectional study using data from 2 randomized controlled trials of survivorship care plans and internet-based self-management intervention in transplantation survivors, the primary objective was to measure HRQoL (using the Short Form-12, version 2.0 [SF-12 v2]), distress (using the Cancer- and Treatment-Related Distress [CTXD] instrument), and health behaviors of myeloma survivors in stable remission after AHCT. A total of 345 patients at a median of 4 years (range, 1.4 to 11 years) post-AHCT were included. The mean SF-12 v2 Physical Component Summary (PCS) score was 45.5 ± 10.5, and the mean Mental Component Summary (MCS) score was 51.3 ± 10.1, compared with US population norms of 50 ± 10 for both (P < .001 and P = .021 for PCS and MCS comparisons, respectively). Notably, neither reached the threshold for a minimal clinically important difference. Approximately one-third of the patients had clinically significant distress based on the CTXD total score, with distress reported by 53% of the patients in the Health Burden domain, by 46% in the Uncertainty domain, by 33% in the Finances domain, by 31% in the Family Strain domain, by 21% in the Identity domain, and by 15% in the Medical Demands domain. Preventive care guidelines were adhered to by 81% of the myeloma survivors; however, adherence to exercise and diet guidelines were relatively low, at 33% and 13%, respectively. Myeloma AHCT survivors in stable remission have no clinically meaningful worsening in physical functioning compared with the general population. Survivorship programs should address ongoing distress due to health burden, uncertainty, and finances in myeloma survivors, along with evidence-based targeted interventions for modifiable health behaviors, such as nutrition and exercise.

Idiopathic Pneumonitis Syndrome After Total Body Irradiation in Pediatric Patients Undergoing Myeloablative Hematopoietic Stem Cell Transplantation: A PENTEC Comprehensive Review.

PURPOSE: Pulmonary complications, especially idiopathic pneumonitis syndrome (IPS), are potentially life altering or fatal sequelae of hematopoietic cell transplantation (HCT). Total body irradiation (TBI) as part of the conditioning regimen has been implicated in IPS. A comprehensive PENTEC (Pediatric Normal Tissues in the Clinic) review was performed to increase our understanding of the role of TBI in the development of acute, noninfectious IPS. METHODS AND MATERIALS: A systematic literature search was conducted using the MEDLINE, PubMed, and Cochrane library databases for articles describing pulmonary toxicity in children treated with HCT. Data pertaining to TBI and pulmonary endpoints were extracted. Risk of IPS was analyzed in relation to patient age, TBI dose, fractionation, dose rate, lung shielding, timing, and type of transplant, with the goal to better understand factors associated with this complication in children undergoing HCT. A logistic regression model was developed using a subset of studies with comparable transplant regimens and sufficient TBI data. RESULTS: Six studies met criteria for modeling of the correlation of TBI parameters with IPS; all consisted of pediatric patients undergoing allogeneic HCT with a cyclophosphamide-based chemotherapy regimen. IPS was variably defined, but all studies that reported IPS were included in this analysis. The mean incidence of post-HCT IPS was 16% (range, 4%-41%). Mortality from IPS, when it occurred, was high (median, 50%; range, 45%-100%). Fractionated TBI prescription doses encompassed a narrow range of 9 to 14 Gy. Many differing TBI methods were reported, and there was an absence of 3-dimensional dose analysis of lung blocking techniques. Thus, a univariate correlation between IPS and total TBI dose, dose fractionation, dose rate, or TBI technique could not be made. However, a model, built from these studies based on prescribed dose using a normalized dose parameter of equivalent dose in 2-Gy fractions (EQD2), adjusted for dose rate, suggested correlation with the development of IPS (P = .0004). The model-predicted odds ratio for IPS was 24.3 Gy-1 (95% confidence interval, 7.0-84.3). Use of TBI lung dose metrics (eg, midlung point dose) could not be successfully modeled, potentially because of dosimetric uncertainties in the actual delivered volumetric lung dose and imperfections in our modeling process. CONCLUSIONS: This PENTEC report is a comprehensive review of IPS in pediatric patients receiving fractionated TBI regimens for allogenic HCT. IPS was not clearly associated with 1 single TBI factor. Modeling using dose-rate adjusted EQD2 showed a response with IPS for allogeneic HCT using a cyclophosphamide-based chemotherapy regimen. Therefore, this model suggests IPS mitigation strategies can focus on not just the dose and dose per fraction but also the dose rate used in TBI. More data are needed to confirm this model and to determine the influence of chemotherapy regimens and contribution from graft-versus-host disease. The presence of confounding variables (eg, systemic chemotherapies) that affect risk, the narrow range of fractionated TBI doses found in the literature, and limitations of other reported data (eg, lung point dose) may have prevented a more straightforward link between IPS and total dose from being observed.

Socioeconomic Factors and Adherence to Health Care Recommendations in Adolescent and Young Adult Cancer Survivors.

Purpose: The majority of adolescent and young adult (AYA) cancer survivors do not receive recommended health care surveillance after therapy. We used cross-sectional survey data to evaluate the impact of income, education, marital status, and insurance on health care adherence among AYA survivors. Methods: Eligible survivors were 18-39 years at diagnosis with invasive malignancy, 1-5 years from therapy completion. Online surveys assessed sociodemographic factors and self-report of completion of recommended health care services. Diagnosis and treatment data were abstracted from medical records. Multivariable logistic regression calculated odds ratios (ORs) and 95% confidence intervals (CIs) for adherence in relation to socioeconomic status and support. Results: Of 344 participants, 36% were adherent to at least 80% of recommendations. Adherence varied by cancer type: 34% for breast cancer, 52% for leukemia/lymphoma, 23% for other tumors. Adherence rates were similar among White, Asian, and Hispanic/Latinx patients. Lower adherence was associated with lower education (OR: 0.43; 95% CI: 0.23-0.80 for <4-year college degree) and lower annual income (OR: 0.51; 95% CI: 0.28-0.95 for $41,000-$80,000; OR: 0.40; 95% CI: 0.19-0.86 for ≤$40,000). Adherence decreased with decreasing income levels among those who were 1 to less than 3 years after diagnosis (OR: 0.25; 95% CI: 0.07-0.93 for $81,000-$120,000; OR: 0.24; 95% CI: 0.07-0.84 for $41,000-$80,000; OR: 0.13; 95% CI: 0.03-0.60 for ≤$40,000). Conclusion: Risk of nonadherence to health care guidelines was associated with lower income and lower education among AYA cancer survivors. Identification of these risks and related barriers to adherence in AYA survivors will inform interventions designed to meet needs of these high-risk groups, particularly during the first years after diagnosis.
