nsive sets of data.Chronic graft-versus-host disease (GVHD) commonly occurs after allogeneic hematopoietic cell transplantation (HCT) despite standard prophylactic immune suppression. Intensified universal prophylaxis approaches are effective but risk possible overtreatment and may interfere with the graft-versus-malignancy immune response. Here we summarize conceptual and practical considerations regarding preemptive therapy of chronic GVHD, namely interventions applied after HCT based on evidence that the risk of developing chronic GVHD is higher than previously appreciated. This risk may be anticipated by clinical factors or risk assignment biomarkers or may be indicated by early signs and symptoms of chronic GVHD that do not fully meet National Institutes of Health diagnostic criteria. However, truly preemptive, individualized, and targeted chronic GVHD therapies currently do not exist. In this report, we (1) review current knowledge regarding clinical risk factors for chronic GVHD, (2) review what is known about chronic GVHD risk assignment biomarkers, (3) examine how chronic GVHD pathogenesis intersects with available targeted therapeutic agents, and (4) summarize considerations for preemptive therapy for chronic GVHD, emphasizing trial development, including trial design and statistical considerations. We conclude that robust risk assignment models that accurately predict chronic GVHD after HCT and early-phase preemptive therapy trials represent the most urgent priorities for advancing this novel area of research.Despite continuing increases in the use of allogeneic hematopoietic cell transplantation (alloHCT) in older adults, no standardized geriatric assessment (GA) has been established to risk stratify for transplantation-related morbidity. We conducted a survey of transplant physicians to determine perceptions of the impact of older age (≥60 years) on alloHCT candidacy, and utilization of tools to gauge candidacy. This 23-item online cross-sectional survey was distributed to HCT physicians caring for adults in the United States between May and July 2019. Of the 770 invited HCT physicians, 175 (22.7%) completed the survey. The majority of respondents were age 41 to 60 years and male and practiced in a higher-volume teaching hospital. When considering regimen intensity, 29 physicians (17%) stated they would consider a myeloablative regimen for patients age ≥70 years, and 141 (82%) would consider reduced-intensity/nonmyeloablative conditioning for patients age ≥70 years. Almost all (90%) endorsed the need for a specialized assessment of pre-HCT vulnerabilities to guide candidacy decisions for older adults. Most physicians reported that their centers rarely (33%) or never (46%) use a dedicated geriatrician/geriatric-oncologist to assess alloHCT candidates age ≥60 years. Common barriers to performing a GA included uncertainty about which tools to use, lack of knowledge and training, and lack of appropriate clinical support staff. Many alloHCT physicians will consider alloHCT in patients up to age 75 years and not uncommonly in patients older than that. However, the application of tools and domains to assess candidacy in older adults varies widely. Incorporation of a standardized pretransplantation health assessment tool for risk stratification is a significant unmet need.Patients undergoing allogeneic hematopoietic cell transplantation (HCT) are at risk for high morbidity and mortality. Advance directives (AD) allow patients to express wishes regarding their care at the end of life, but these are not completed in the majority of patients undergoing HCT, with only 44% of deceased allogeneic HCT recipients at this institution completing an AD in the past decade. Increasing the AD completion rate can improve the quality of care for allogeneic HCT recipients. Our objective was to evaluate whether an alternative AD instrument can increase AD completion rate and patient satisfaction. We conducted a prospective, randomized controlled study of the traditional California AD versus a novel Letter AD, the Stanford What Matters Most Letter, in adult allogeneic HCT recipients. Patients age ≥18 years undergoing first allogeneic HCT at Stanford University were eligible. Prior to HCT conditioning, enrolled patients were assigned at random to complete either the traditional AD or the Letter Aicantly differ based on AD version.Progressive resistance training (PRT) combined with weight-bearing impact exercise are recommended to optimize bone health, but the optimal frequency and dose of training remains uncertain. This study, which is a secondary analysis of an 18-month intervention in men aged 50-79 years, examined the association between exercise frequency and the volume of training with changes in DXA and QCT-derived femoral neck (FN) and lumbar spine (LS) bone outcomes, respectively. Men were allocated to either thrice-weekly PRT plus impact exercise training (n = 87) or a non-exercising (n = 85) group. Average weekly exercise frequency (ExFreq) and training volume per session [PRT volume (weight lifted, kg), number of weight-bearing impacts (jumps completed) and total training volume] over the 18-months were calculated from the participants' exercise cards. Regression analysis showed that average weekly ExFreq and training volume per session were positively associated with the 18-month changes in FN BMD and LS trabecular volumetric BMD. Men completing on average 1 to less then 2 and ≥2 sessions/week had a 1.6 to 2.2% greater net gain in FN BMD relative to non-exercising men, while those completing ≥2 sessions/week had 3.9 to 5.2% net gain in LS trabecular vBMD compared to non-exercising men and those completing less then 1 session/week. Further analysis showed that the average number of impact loads per session, but not the average PRT weight-lifted, was positively associated with changes in BMD. selleck kinase inhibitor Every 10 impact loads per session over 18 months was associated with a 0.3% and 1.3% increase in FN BMD and LS trabecular vBMD, respectively. In conclusion, this study indicates that exercise frequency and training volume were predictors of the changes in hip and spine BMD following a multi-component exercise program, and that the number of impact loads rather than PRT weight lifted per session was more important for eliciting positive skeletal responses in middle-aged and older men.
