Objective: To better evaluate the relationships between training, demographics, and injury, this study sought to define race-related injury risk factors for half- and full-marathon runners. Design: This 3-year, observational cross-sectional study included adults who participated in a half or full marathon. Prerace and 2-week postrace surveys collected data on demographics, training factors, and injuries. Setting: This study took place during a nationally recognized marathon affiliated with a local hospital. Participants: Runners were recruited during the Expo in the days before the race. Postrace surveys were returned by 1043 half marathoners and 624 full marathoners (response rate, 83%). Interventions: This was an observational study; independent variables included demographic data and race year. Main Outcome Measure: The primary outcome was race-related injury that occurred during the race or within 2 weeks after the race. Results: Race-related injuries were reported by 24% of half marathoners and 30% of full marathoners. For half and full marathoners, respectively, significant factors for injuries were previous injury, lower peak weekly training mileage, and lower weekly mileage before race training. Factors significant for only half-marathon injuries were younger age, female sex, shorter distance of longest training run, and no formal training program. Factors significant for only full-marathon injuries were higher body mass index, fewer days running per week, and fewer years of running experience. Conclusions: Previous running injuries, undertraining, and inexperience increased race-related injury risk; women had higher risk than men. Decreased risk of injury was associated with training loads of greater than 23 miles/week for half marathoners and 40 miles/week for full marathoners.

Purpose The purpose of this study was to investigate associations between performance on a clinical speech-in-noise measure with a comprehensive neurocognitive battery of tests. Method A group of older adults ( N = 250, M age = 77 years, age range: 67.3–89.1 years) enrolled in the Atherosclerosis Risk in Communities Neurocognitive Study took part in the hearing pilot study (2013) that included testing for audiometric thresholds and speech-in-noise performance (Quick Speech-in-Noise Test; Killion, Niquette, Gudmundsen, Revit, & Banerjee, 2004). This research study analyzed the associations between domain-specific cognitive function and speech-in-noise performance after adjusting for hearing thresholds and other demographic and cardiovascular factors. Results Multivariable-adjusted associations were found between all cognitive domains and speech-in-noise performance in the full sample, but the observed associations varied when participants with varying levels of moderate to moderately severe hearing loss were excluded from the analysis. Conclusions The findings are discussed in terms considering the cognitive status of older adults in relation to their speech-in-noise performance during audiological evaluation and implications for aural rehabilitation.

AbstractIntroductionConventional Z‐scores are generated by subtracting the mean and dividing by the standard deviation. More recent methods linearly correct for age, sex, and education, so that these “adjusted” Z‐scores better represent whether an individual's cognitive performance is abnormal. Extreme negative Z‐scores for individuals relative to this normative distribution are considered indicative of cognitive deficiency.MethodsIn this article, we consider nonlinear shape constrained additive models accounting for age, sex, and education (correcting for nonlinearity). Additional shape constrained additive models account for varying standard deviation of the cognitive scores with age (correcting for heterogeneity of variance).ResultsCorrected Z‐scores based on nonlinear shape constrained additive models provide improved adjustment for age, sex, and education, as indicated by higher adjusted‐R2.DiscussionNonlinearly corrected Z‐scores with respect to age, sex, and education with age‐varying residual standard deviation allow for improved detection of non‐normative extreme cognitive scores.

Introduction: Medical schools have an enduring need to provide ongoing faculty development and to foster educational alliances between teachers and learners, so that feedback provided to learners is both frequent and of high quality. We hypothesized that medical students trained as academic detailers with a mission to increase the emphasis on feedback could serve in this role during our clerkship, while still being evaluated as students in our clerkship rotation. Methods: The family medicine clerkship at Mayo Clinic School of Medicine launched a revised curriculum in 2016 in which students were taught how they might build an educational alliance with preceptors, were taught characteristics of high-quality feedback, and practiced requesting more useful feedback when initial quality was poor. After utilizing a clerkship-specific curriculum with small group sessions on receiving feedback, and training students and preceptors on the SNAPPs model, students were then directed to request feedback from their preceptors and model successful feedback conversations for preceptors. The study evaluated the medical students’ summative evaluations to compare the rate from the preintervention year (2015-2016) and the intervention year (2016-2017) at which preceptors added comments on students’ use of feedback. Results: Preceptors’ written comments about students seeking feedback increased at about a four-fold rate (74.4% vs 18.8%, P<.001) after implementing a suite of changes to our clerkship curriculum. Conclusions: Using medical students to change preceptor behaviors was an important part of our suite of interventions. This intervention directed preceptor attention toward our instructional goal of increased medical student feedback.

Although scholars have long studied circumstances that shape prejudice, inquiry into factors associated with long-term prejudice reduction has been more limited. Using a 6-year longitudinal study of non-Black physicians in training ( N = 3,134), we examined the effect of three medical-school factors—interracial contact, medical-school environment, and diversity training—on explicit and implicit racial bias measured during medical residency. When accounting for all three factors, previous contact, and baseline bias, we found that quality of contact continued to predict lower explicit and implicit bias, although the effects were very small. Racial climate, modeling of bias, and hours of diversity training in medical school were not consistently related to less explicit or implicit bias during residency. These results highlight the benefits of interracial contact during an impactful experience such as medical school. Ultimately, professional institutions can play a role in reducing anti-Black bias by encouraging more frequent, and especially more favorable, interracial contact.

Abstract Introduction. CLL primarily affects elderly individuals who frequently have comorbid health conditions. It is typically assumed non-CLL-related etiologies will be the ultimate cause of death for most CLL patients, particularly those with comorbid conditions at diagnosis. Methods. Between 9/2002 and 11/2014, 1174 patients with newly diagnosed CLL were enrolled in a prospective cohort study evaluating the natural history of CLL. Comorbidities were prospectively recorded at the time of diagnosis. Comorbidities arising during the course of disease were not considered for this analysis. Standardized longitudinal follow-up was performed in all patients every 6 months for the first 3 years after diagnosis and annually thereafter through 04/2015. Internal and external medical records, death certificates, and information from next of kin were centrally reviewed to determine cause of death, using a standardized protocol. Categorical and continuous variables were evaluated using the c2 or Fisher exact tests and the Mann-Whitney test, as appropriate. Results. Baseline characteristics at time of CLL diagnosis are shown in the Table. Over 80% of patients had 2 or more comorbidities at diagnosis (median 3, range 0-11). After a median follow up of 5 years, 224 (19%) patients have died. The cause of death could be accurately determined in 183 (82%) of these patients. The cause of death was due to CLL in 135 (74%), including 84 (46%) CLL progressions, 14 (8%) infections, and 37 (20%) other cancers. Death was due to non-CLL-related causes (such as congestive heart failure, stroke or chronic obstructive pulmonary disease) in the remaining 48 (26%) patients. On univariable analysis, age and number of comorbid health conditions were not related to whether or not the cause of death was related/unrelated to CLL. The only specific co-morbid condition at diagnosis that predicted for non-CLL related death was stroke (8% vs 1%, p=0.04). Unmutated IGHV was the only prognostic factor thatpredicted greater likelihood of CLL-related death (70% vs 50%, p=0.03). Conclusions. The majority of patients with CLL have multiple comorbidities at time of diagnosis. Despite this fact, CLL progression and/or CLL-related complications are the primary cause of death. The number and type of comorbidities at diagnosis have minimal relationship to whether or not the ultimate cause of death was CLL-related. In contrast, the CLL-specific characteristic IGHV status (but interestingly not FISH defects) correlates with cause of death. Collectively, these findings illustrate the need for more effective CLL therapy, particularly treatments that can be tolerated by patients with comorbid health conditions. It is hoped the signaling inhibitors may help address this unmet need. Table.

Abstract Background: Phlebotomy is a common and established treatment in patients diagnosed with polycythemia vera (PV) to reduce the risk of thromboembolic events, in both acute and chronic settings. However, phlebotomy may not alleviate all PV-related symptoms and its frequent application can cause moderate to profound iron deficiency, which may worsen PV-related symptoms. This analysis of MPN Landmark survey data examined patient-reported quality of life (QoL) and productivity outcomes in patients with PV based on phlebotomy treatment history. Methods: Patients who were diagnosed with a myeloproliferative neoplasm (MPN) were recruited to participate in the MPN Landmark survey in the US (fielded May - July 2014). This analysis describes responses from patients with PV on questions regarding PV-related symptom burden, QoL, and productivity. Patient responses were analyzed based on phlebotomy treatment history and included patients who were actively receiving phlebotomy within the last 3 months (≥1 per month, every other month, and every 3 months or longer), had discontinued phlebotomy, or were phlebotomy-naive. Descriptive statistical analyses were used to evaluate these outcomes based on phlebotomy frequency, as appropriate. Results: Overall, 813 patients completed the Landmark survey, and 274 out of the 380 patients with PV who completed the survey were evaluable for this analysis. Mean age ranged from 61.6-65.4 years among phlebotomy subgroups (Table 1). The average duration of PV was longest among patients with PV who had discontinued phlebotomy (12.0 years) compared with phlebotomy-naive patients (6.3 years) and patients actively treated with phlebotomy (5.9-8.9 years). The percentage of patients diagnosed within 1 year of the survey ranged from 4.1% to 11.5% among the patients who had been treated with phlebotomy and was 15.4% in the phlebotomy-naive subgroup. Most patients reported PV-related symptoms; symptom burden was similar in all phlebotomy subgroups. Fatigue was the most common symptom reported in all subgroups (range, 71.4%-80.8%). QoL measures were generally worse with higher phlebotomy frequency (Table 1). Similarly, more frequent phlebotomy procedures was found to be associated with reduced productivity: patients who received ≥1 phlebotomy per month had the highest mean number (in the preceding 30 days) of sick days (among patients employed), days spent in bed, and days with plans canceled. Of note, approximately one third of patients receiving more frequent phlebotomy procedures were also receiving concomitant hydroxyurea to manage their PV (≥1 per month, 38.5%; every other month, 36.4%). Conclusion: Patients with PV may experience disease-related symptoms and reductions in QoL and work productivity. Frequent phlebotomy procedures were associated with increasingly worsened QoL and decreased work productivity. Further research is needed to better understand the impact of phlebotomy on patient-reported outcomes in patients with PV.

Abstract Background: Single autologous stem cell transplant (ASCT) is considered the standard of care for younger multiple myeloma (MM) patients (pts). However, it is not curative and virtually all patients will ultimately relapse. As more options, such as biological therapy, are available to treat relapsed disease, the role of a second ASCT as salvage therapy is unclear. Method: Retrospective review of all MM pts who received a 2nd ASCT as salvage therapy at Princess Margaret Hospital. Results: Between February 1997 and June 2007, 61 MM pts received a second ASCT for relapsed MM at our institution. Median age was 56 yrs (range 35–71) at second transplant. 37 pts (61%) were male. Immunoglobulin subtype included IgG (36), IgA (14), light chain (6), nonsecretory (3), IgM(1) and IgD (1). Transplant conditioning regimen for first transplant was high dose melphalan (MEL) 140–200 mg/m2 in 51, MEL/etoposide(E)/TBI in 4, and MELl/TBI in 2. 2nd ASCT conditioning consisted of MEL + TBI +/− E in 2, MEL alone in 58 and Busulfan/Cyclophosphomide in 1. The median time from diagnosis to first transplant was 9.7 months (2.0–74.2). The median time to relapse after the first transplant was 32.6 months (9.7–85.6), with a median interval between transplants of 45.1 months (19.7– 115). Two transplant-related deaths occurred (3%). Response to first transplant was 4 CR (8%), 34 PR (68%), 2 MR (4%) and 10 SD (20%). Nineteen pts went on to maintenance therapy between transplants. Response to second transplant was 4 CR (8%), 41 PR (80%), 5 SD (10%) and 1 PD (2%). Median progression-free survival (PFS) was 15.8 months (0–63.8) while median overall survival (OS) was 4.2 years (0–7.0) after 2nd ASCT. The relationship between progression-free interval after 1st ASCT and the outcome of the 2nd ASCT is summarized Table 1. Patients can be stratified into two groups, those with a disease free interval of less than or greater than 24 months. The use of maintenance therapy did not differ between the two groups, 6 (40%) in patients with PFS ≤24 months and 13 (28%) in patients with PFS >24 months. Conclusions: 2nd ASCT is a feasible and safe salvage therapy in patients with relapsed MM. 2nd ASCT is effective in providing a median progression free survival of 1.25 years and median overall survival of 4.2 years after 2nd ASCT - results that compare favourably with other salvage approaches. Patients with a longer disease free interval after 1st ASCT experience a better progression free survival and overall survival after 2nd ASCT. It is reasonable, therefore, to consider a 2nd ASCT if the time to progression is greater than 2 years after first ASCT.

Introduction: Despite advances in treatment strategy, multiple myeloma (MM) remains a challenging, incurable disease as patients (pts) often relapse. Here we describe preclinical data of a novel cereblon (CRBN) E3 ligase modulatory compound (CELMoD), iberdomide (IBER; CC-220), as well as clinical and translational data from a current phase 1/2 clinical trial (NCT02773030). These data support a differentiated profile for IBER from immunomodulatory agents (IMiD agents), and development of IBER as a foundation of combination therapy for the treatment of relapsed/refractory MM (RRMM). Methods: Preclinical analyses were performed on pomalidomide (POM)-sensitive and acquired-resistant MM cell lines and peripheral blood mononuclear cells from healthy volunteers. Eligible pts enrolled on the clinical trial had RRMM and had received ≥ 2 prior regimens, containing at least an IMiD agent and proteasome inhibitor (PI), and had experienced disease progression within 60 days of last MM therapy. Escalating doses of IBER were given on Days 1-21, in combination with dexamethasone (DEX; 40 mg; 20 mg in pts aged > 75 years) on Days 1, 8, 15, and 22, of each 28-day cycle. Immunohistochemistry (IHC) data on CRBN, Ikaros, Aiolos, and ZFP91 expression was obtained from pt bone marrow specimens at screening and at Cycle 2, Day 15. Immune profiling was evaluated by flow cytometry of peripheral blood at Cycle 1, Day 1 and Cycle 2, Day 15. Primary objectives were to evaluate maximum tolerated dose (MTD), recommended phase 2 dose (RP2D), safety, and preliminary efficacy. Results: Preclinically, IBER exhibited potent tumoricidal anti-MM and immunostimulatory activity. IBER was more potent than lenalidomide (LEN) or POM in overcoming the immunosuppressive activity of bortezomib (BORT), inducing a more than twofold increase in T cell proliferation in the presence of BORT. IBER also enhanced the antibody-dependent cell-mediated cytotoxicity and complement-dependent cytotoxicity of daratumumab (DARA), leading to deeper responses than combinations with LEN or POM. Further differentiating from both LEN and POM, IBER showed activity alone and in combination with BORT or DARA in POM-resistant MM cell lines. As of June 28, 2019, 69 pts with RRMM had received IBER + DEX. Median age was 65 years (range 33-80), and median number of prior regimens was 5 (range 2-12). Prior therapies included autologous stem cell transplantation (80%), LEN (100%), POM (70%), PIs (100%), DARA (71%) and anti-BCMA (6%), including CAR T cells. Clinical activity was observed across all dose levels with an overall response rate (ORR) of 29%, clinical benefit rate of 45%, and disease control rate of 80%. ORR was 30%, 28% and 29% in IMiD agent-refractory, DARA-refractory and Quad-class (IMiD agents/PIs/steroids/CD-38 antibodies)-refractory pts, respectively. IBER + DEX showed a favorable safety profile, with grade 3-4 neutropenia, infections, and thrombocytopenia, occurring in 29%, 25%, and 12% of pts, respectively. To date, IBER doses range from 0.3 to 1.3 mg and the MTD/RP2D has not yet been reached. Pharmacodynamic immunophenotyping changes were dose-dependent. Treatment with IBER (at doses > 0.75mg) + DEX doubled the percentage of proliferating T cells and NK cells (P < 0.001 for each) and increased activated and effector memory CD8+ and CD4+ T cells by > 50% (P < 0.01 for each subset). Pharmacodynamic changes in pt bone marrow by quantitative IHC scoring showed significant degradation of substrates (Ikaros, P = 0.006; Aiolos, P < 0.001; ZFP91, P < 0.001) and downregulation of c-myc (P = 0.027), including in pts refractory to POM and with low CRBN expression. Conclusions: IBER + DEX has shown notable clinical activity and favorable tolerability in heavily pretreated pts with RRMM, including pts refractory to prior IMiD therapy. Preclinical and translational data suggest a differentiated profile of IBER from IMiD agents in regard to activity in POM-resistant models, potency in combination with BORT and DARA, and by inducing changes in CD4+ T cells that were not observed in pts treated with POM from prior studies. Taken together, these data support a differentiated profile for IBER from IMiD agents, and the clinical development of IBER as a foundation of combination therapy for the treatment of RRMM. This study is ongoing, and includes cohorts evaluating the combinations of IBER + DEX with DARA, BORT, and carfilzomib. Updated results will be presented at the meeting.
