Sleep is critical to athlete health and sport performance. Purpose To evaluate the relationship between objective sleep data and next-day basketball game performance. Methods Collegiate men basketball athletes (n = 4) wore smart ring sleep trackers the night before games (n = 22). Sleep variables included hours of total sleep (TS), rapid eye movement sleep duration (RM), deep sleep duration (DS), and heart rate variability (HRV). Game performance was evaluated using field goal percentage (FG%) and player efficiency (EFF). Results TS, RM, DS, and HRV demonstrated very weak relationships with FG% ( p > 0.05) and EFF ( p > 0.05). Individual player analysis revealed one athlete exhibited strong to moderate correlations for TS-EFF (r = 0.67), RS-EFF (r = 0.41), TS-FG% (r = 0.51), and RM-FG% (r = 0.67) ( p < 0.05). Sleep metrics had no effect on FG% (R 2 = 0.025) and EFF (R 2 = 0.053) ( p > 0.05). Conclusions Results suggest a lack of group-level associations between smart ring-measured sleep variables and next-day game performance. This highlights the need for individualized sleep monitoring rather than relying solely on objective metrics.

Purpose: This study examined if vertical bladder excursion during pelvic floor muscle (PFM) contraction, measured with transabdominal ultrasound (TAUS), improved following a single training session 0-5 days postpartum. It also assessed patient satisfaction with the training. Methods: 75 healthy, female volunteers within 0-5 days post-vaginal delivery were recruited during their inpatient postpartum stay. Participants completed one in-person session involving a standardized bladder filling protocol, TAUS imaging during PFM contractions, a PFM training session using TAUS as visual biofeedback, and a two-question post intervention survey. Vertical bladder base excursions were compared pre- and post- training between two groups: those whose bladder bases descended and those whose ascended during baseline contractions. A mixed model ANOVA with one between-group factor (baseline descenders vs. ascenders) and one within-group factor (pre- vs. post-training) analyzed the change in bladder lift. Patient satisfaction was assessed with Likert scales. Results: Mean vertical excursion increased from 0.12 cm (SD = 0.48) to 0.32 cm (SD = 0.33) post-training, which was statistically significant (p <.001, Cohens d = 0.767). Greater improvements were noted in those with a bladder base descent at baseline. All participants reported the experience to be helpful or very helpful and were satisfied or very satisfied. Discussion: Participants increased vertical bladder excursion during PFM contraction with TAUS biofeedback within a single session, especially those with baseline paradoxical bladder excursion and perineal trauma during delivery. Participants found the experience helpful and satisfying, suggesting TAUS biofeedback may be a useful tool in early postpartum PFM rehabilitation.

Abstract Background and Aims Classification and risk stratification in aortic (AR), mitral (MR), and tricuspid regurgitation (TR) remains a significant clinical challenge. This study aimed to develop an artificial intelligence (AI) system to assess valvular regurgitation and stratify MR-progression risk. Methods Using transthoracic echocardiograms (TTEs) at two sites (internal development/test, external test), the DELINEATE-Regurgitation system was developed to classify AR, MR, and TR severity using colour Doppler videos. Methods of summating video-level classifications into study-level predictions were tested, comparing single-view with multiview approaches integrating predictions across multiple videos. Model agreement with cardiologists was assessed by weighted kappa. A separate AI system (DELINEATE-MR-Progression) analysing colour Doppler videos was developed to predict which patients with mild, mild–moderate, and moderate MR were most likely to progress to moderate–severe or severe MR with analysis by Kaplan–Meier and Cox proportional hazards models. Results A total of 71 660 TTEs with 1 203 980 colour Doppler videos were included. The weighted kappa in internal/external test sets for regurgitation classification was 0.81/0.76 for AR, 0.76/0.72 for MR, and 0.73/0.64 for TR using a multiview approach taking all colour Doppler videos in a study, demonstrating substantial agreement with cardiologist interpretation with superiority of multiview over single view approaches. In the progression analysis, the AI score stratified MR-progression risk even when controlled for clinical factors known to be associated with MR progression [internal test set hazard ratio 4.1 (95% confidence interval 2.5–6.6)]. Conclusions An AI system can accurately classify AR, MR, and TR and predict MR progression beyond currently known risk factors.

Abstract This retrospective analysis aimed to provide evidence-based risk stratification of TP53-mutated (TP53mut) myeloid neoplasms (MNs). Of 580 MNs harboring TP53mut with variant allele frequency (VAF) ≥2%, 219 (37.8%), 194 (33.4%), 92 (15.9%), and 75 (12.9%) were classified as acute myeloid leukemia (AML), myelodysplastic syndrome (MDS) with low blasts (MDS-LB), MDS with excess blasts (MDS-EB)-2, and -EB1 according to the revised fourth edition of the World Health Organization (WHO) classification, respectively. Hierarchical analysis identified the following 4 risk groups with distinct survival: (1) MDS-LB, (2) MDS-EB1/EB2/AML VAF &lt;10%, (3) MDS-EB1/EB2 VAF ≥10%, and (4) AML VAF ≥10%. We next evaluated the impact of allelic status, VAF, and complex karyotype (CK). In our cohort, the significance of biallelic status was limited to MDS with &lt;5% blasts and not for blasts 5% to 9%, as proposed by the International Consensus Classification (ICC), or 5% to 19%, as proposed by the fifth edition of the WHO (WHO-5). MDS-EB1 and -EB2 with VAF ≥10% had comparable survival (9.6 vs 7.2 months; P = .12), regardless of allelic status. Contrary to the ICC proposal, MDS-EB1/EB2 with VAF &lt;10% and CK had poor survival compared with those without CK, comparable to MDS-EB1/EB2 with VAF ≥10% (5.6 vs 26.2 vs 6.3 months; P = .003). Survival of TP53mut AML was poor (median 3.9 months) regardless of allelic/CK status. Thus, using ICC or WHO-5 may underestimate prognosis of MDS with blasts 5% to 19% and 5% to 9%, respectively. Collectively, the hierarchical model acknowledges poor survival of 91.9% TP53mut MDS and AML compared with 36.5% and 80.7% by WHO-5 and ICC, respectively.

Peroxisomes are vital but often overlooked metabolic organelles. We found that excessive interferon signaling remodeled macrophage peroxisomes. This loss of peroxisomes impaired inflammation resolution and lung repair during severe respiratory viral infections. Peroxisomes were found to modulate lipid metabolism and mitochondrial health in a macrophage type-specific manner and enhanced alveolar macrophage-mediated tissue repair and alveolar regeneration after viral infection. Peroxisomes also prevented excessive macrophage inflammasome activation and IL-1β release, limiting accumulation of KRT8 high dysplastic epithelial progenitors following viral injury. Pharmacologically enhancing peroxisome biogenesis mitigated both acute symptoms and post-acute sequelae of COVID-19 (PASC) in animal models. Thus, macrophage peroxisome dysfunction contributes to chronic lung pathology and fibrosis after severe acute respiratory syndrome coronavirus 2 infection.

PURPOSE In patients with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL), brentuximab vedotin (BV) as monotherapy or combined with either lenalidomide (Len) or rituximab (R) has demonstrated efficacy with acceptable safety. We evaluated the efficacy and safety of BV + Len + R versus placebo + Len + R in patients with R/R DLBCL. METHODS ECHELON-3 is a randomized, double-blind, placebo-controlled, multicenter, phase 3 trial comparing BV + Len + R with placebo + Len + R in patients with R/R DLBCL. Patients received BV or placebo once every 3 weeks, Len once daily, and R once every 3 weeks. The primary end point was overall survival (OS), and secondary end points included investigator-assessed progression-free survival (PFS) and objective response rate (ORR). A prespecified interim analysis was performed after 134 OS events, with two-sided P = .0232 as the efficacy boundary. RESULTS Patients (N = 230) were randomly assigned to receive BV + Len + R (n = 112) or placebo + Len + R (n = 118). Two patients in the placebo arm did not receive treatment. With a median follow-up of 16.4 months, the median OS was 13.8 months with BV + Len + R versus 8.5 months with placebo + Len + R (hazard ratio, 0.63 [95% CI, 0.45 to 0.89]; two-sided P = .009). The median PFS was 4.2 months with BV + Len + R versus 2.6 months with placebo + Len + R (hazard ratio, 0.53 [95% CI, 0.38 to 0.73]; two-sided P < .001). The ORR was 64% ([95% CI, 55 to 73]; two-sided P < .001) with BV + Len + R and 42% (95% CI, 33 to 51) with placebo + Len + R; complete response rates were 40% and 19%, respectively. Treatment-emergent adverse events (AEs) occurred in 97% of patients in both arms. In both arms, the most common treatment-emergent AEs were neutropenia, thrombocytopenia, diarrhea, and anemia. CONCLUSION BV + Len + R demonstrated a statistically significant survival benefit with a manageable safety profile in heavily pretreated patients with R/R DLBCL.

Introduction Age correlates with survival in patients (pts) with DLBCL, which has a median age at diagnosis of 67 y. Recent therapeutic advances, including bispecifics and cell therapy, have promising efficacy, but safety and accessibility continue to be limited for older pts. The randomized, global, phase 3 ECHELON-3 study (NCT04404283) demonstrated a statistically significant and clinically meaningful improvement in overall survival (OS), progression-free survival (PFS), and overall response rate (ORR) with brentuximab vedotin (BV) + lenalidomide (Len) + rituximab (R; BV+Len+R) vs placebo+Len+R in pts with R/R DLBCL after ≥ 2 prior systemic therapies who were ineligible for hematopoietic stem cell transplant and/or chimeric antigen receptor (CAR) T-cell therapy. Here, we present safety and efficacy in pts aged ≥65 y. Methods In ECHELON-3, pts were randomized 1:1 to receive BV (1.2 mg/kg) or placebo every 3 weeks (q3w), in combination with R (375 mg/m2) q3w and Len (20 mg) once daily. Granulocyte colony-stimulating factor was required in all cycles. Efficacy was assessed by investigators per Lugano 2014 classification. The primary endpoint was OS, with key secondary endpoints of PFS and ORR. Other secondary endpoints included detailed safety and tolerability. This subgroup analysis comprises pts aged ≥65 y. P values are descriptive. Results A total of 155 pts aged ≥65 y were enrolled from April 2021 to November 2023 and randomized to BV+Len+R (n=79) or placebo+Len+R (n=76). The median age was 75 y (range, 65-89 y); 54% of pts were male, 59% were White, and 19% were Asian. Twenty-three percent and 54% had Ann Arbor stage III and IV disease, respectively, and 64% had high-intermediate or high International Prognostic Index scores (3-5) at enrollment. The most common DLBCL subtype was DLBCL not otherwise specified (58%). Twenty-nine percent of pts had transformed DLBCL. Approximately half (49%) of pts had primary refractory disease, and 81% had disease refractory to their most recent prior line of therapy. Seventy percent of pts had &lt;1% CD30 expression via IHC; 48% of cases had germinal center B-cell origin. Prior CAR-T was reported in 21.9% of pts. At a median follow-up of 16.8 mo (95% CI, 14.3-19.5 mo), median OS was 15.9 mo (95% CI, 11.7 mo-not estimable [NE]) with BV+Len+R vs 8.5 mo (95% CI, 5.5-11.5 mo) with placebo+Len+R (hazard ratio [HR], 0.540; 95% CI, 0.351-0.830; P=.0043). Median PFS was 5.7 mo (95% CI, 4.1-12.7 mo) with BV+Len+R vs 2.8 mo (95% CI, 1.9-4.1 mo) with placebo+Len+R (HR, 0.478; 95% CI, 0.318-0.718; P=.0003). ORR was 70.9% (95% CI, 59.6%-80.6%) with BV+Len+R vs 46.1% (95% CI, 34.5%-57.9%) with placebo+Len+R (P=.0020); complete response (CR) rate was 45.6% vs 19.7%, respectively. Median time to CR was 1.61 mo with both BV+Len+R and placebo+Len+R (range, 1.2-7.3 vs 0.7-4.6 mo, respectively). Median duration of CR was 18.9 mo (95% CI, 12.4 mo-NE) with BV+Len+R vs 5.4 mo (95% CI, 2.8 mo-NE) with placebo+Len+R (HR, 0.416; 95% CI, 0.139-1.250). In total, 154 pts were evaluable for safety analysis (75 pts in placebo+Len+R group). The median number of cycles was 5 (range, 1-34) vs 3 (range, 1-31) in the BV+Len+R and placebo+Len+R groups, respectively. The percentage of pts with any treatment-emergent adverse event (TEAE) was similar between groups (97% with BV+Len+R and 99% with placebo+Len+R); grade ≥3 TEAEs occurred in 89% of pts in the BV+Len+R group and 76% in the placebo+Len+R group. Serious TEAEs and TEAEs leading to death were reported more frequently in the BV+Len+R group (62% and 13%, respectively) than the placebo+Len+R group (47% and 8%, respectively). More pts discontinued study treatment due to TEAEs in the BV+Len+R group than the placebo+Len+R group (20% vs 8%). In total, 39% of pts on BV+Len+R had a peripheral neuropathy event vs 27% of pts on placebo+Len+R; however, the majority of cases were grade 1 (22% and 17%, respectively). Additional information on older pts will be presented. Conclusions BV+Len+R demonstrated a clinically meaningful improvement in all key efficacy outcomes in pts aged ≥65 y, which is consistent with the overall ECHELON-3 population (median age 74 y; 70.5% of pts aged ≥65 y in BV+Len+R group). Differences in some safety endpoints are likely attributable to longer duration of treatment in the BV+Len+R group. No clinically meaningful safety trends in pts aged ≥65 y were identified. These results suggest that BV+Len+R may be an effective treatment option in older pts with R/R DLBCL.

Introduction Patients (pts) with progressive disease after ≥2 prior lines of systemic therapy are unlikely to derive additional benefit from current salvage immunochemotherapies, and survival declines significantly with each subsequent treatment. Pts with refractory disease following second-line therapy have worse outcomes, with reported overall response rates (ORRs) of 1% to 14% and overall survival (OS) of 5 months (Blood. 2017;130[16]:1800-1808). While chimeric antigen receptor (CAR) T-cell therapy has become a preferred strategy in the second- and third-line settings, pts with R/R disease following CAR-T experience dismal survival, with progression-free survival (PFS) and OS as low as 3 and 5 months, respectively, and no agreed standard of care post CAR-T (Blood. 2022;140[24]:2527-2529). The randomized, global, phase 3 ECHELON-3 study (NCT04404283) was conducted in pts with R/R DLBCL after ≥2 prior therapies who were ineligible for hematopoietic stem cell transplant and/or CAR-T. Here, we present subgroup analyses in pts with 2 prior lines of therapy, refractory disease, or prior CAR-T. Methods In these subgroup analyses of ECHELON-3, eligible pts had 2 prior lines of systemic therapy, disease refractory to the last prior therapy, or prior exposure to CAR-T. Pts could qualify for ≥1 subgroup and were analyzed separately. Refractory disease was defined as stable or progressive disease as best overall response to last line of treatment or relapse ≤6 months from the end of treatment. Pts were randomized 1:1 to receive brentuximab vedotin (BV; 1.2 mg/kg) or placebo every 3 weeks (q3w), in combination with rituximab (R; 375 mg/m2) q3w and lenalidomide (Len; 20 mg) once daily. Efficacy was assessed by investigators per Lugano 2014 classification. The primary endpoint was OS, with key secondary endpoints of PFS and ORR. P values are descriptive. Results In total, 230 pts were enrolled in ECHELON-3 from April 2021 to November 2023, with a median follow-up of 16.4 months (range, 0.1-31.5 months). Overall, 94 pts with 2 prior lines of systemic therapy were enrolled and randomized to BV+Len+R (n=48) or placebo+Len+R (n=46). Median OS was 16.3 months (95% CI, 12.6 months-not estimable) with BV+Len+R vs 8.5 months (95% CI, 4.1-15.8 months) with placebo+Len+R (hazard ratio [HR], 0.557; 95% CI, 0.317-0.977; P=.0388). Median PFS was 7.1 months (95% CI, 3.6-12.6 months) with BV+Len+R vs 2.7 months (95% CI, 1.4-4.0 months) with placebo+Len+R (HR, 0.462; 95% CI, 0.279-0.764; P=.0020). ORR was 68.8% (95% CI, 53.7%-81.3%) with BV+Len+R vs 43.5% with placebo+Len+R (95% CI, 28.9%-58.9%; P=.0216); complete response (CR) rate was 52.1% vs 13.0%, respectively. Additional data for pts by lines of therapy received will be presented. In total, 194 pts with disease refractory to the most recent systemic therapy were enrolled and randomized to BV+Len+R (n=98) and placebo+Len+R (n=96). Median OS was 11.7 months (95% CI, 8.8-16.3 months) with BV+Len+R vs 5.5 months (95% CI, 3.7-8.5 months) with placebo+Len+R (HR, 0.566; 95% CI, 0.396-0.808; P=.0015). Median PFS was 4.1 months (95% CI, 2.8-5.4 months) with BV+Len+R vs 1.5 months (95% CI, 1.4-2.6 months) with placebo+Len+R (HR, 0.508; 95% CI, 0.363-0.712; P&lt;.0001). ORR was 59.2% (95% CI, 48.8%-69.0%) with BV+Len+R vs 29.2% (95% CI, 20.3%-39.3%) with placebo+Len+R (P&lt;.0001); CR rate was 34.7% vs 11.5%, respectively. Overall, 67 pts who received prior CAR-T were enrolled and randomized to BV+Len+R (n=32) and placebo+Len+R (n=35). Median OS was 15.6 months with BV+Len+R vs 4.4 months with placebo+Len+R (HR, 0.38; 95% CI, 0.2-0.75). Median PFS was 3.0 months with BV+Len+R vs 1.4 months with placebo+Len+R (HR, 0.41; 95% CI, 0.22-0.76). ORR was 65.6% (95% CI, 46.8%-81.4%) with BV+Len+R vs 25.7% (95% CI, 12.5%-43.3%) with placebo+Len+R (P=.0014); CR rate was 37.5% vs 11.4%, respectively. Conclusions BV+Len+R demonstrated a clinically meaningful improvement in all key efficacy outcomes, including CR and OS, in pts with 2 prior lines of therapy, disease refractory to prior treatment, or prior CAR-T. This treatment benefit was generally consistent with that observed in the overall ECHELON-3 study population. Therefore, BV+Len+R has the potential to address an unmet need for effective and tolerable therapy in heavily pretreated pts, as described above.

Introduction Relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) is very aggressive, with a historically low complete response (CR) rate (Blood. 2017; 130[16]:1800-1808). Recent research has focused on achieving complete and durable responses in this population, which translate to improvements in overall survival (OS) and progression-free survival (PFS). Results from the randomized, global, phase 3 ECHELON-3 study (NCT04404283) demonstrated a statistically significant and clinically meaningful improvement in OS, PFS, and objective response rate with brentuximab vedotin (BV) combined with lenalidomide (Len) and rituximab (R; BV+Len+R) vs placebo+Len+R in patients (pts) with R/R DLBCL after ≥2 prior systemic therapies. Here, we present subgroup analyses in pts with a best overall response (BOR) of CR (n=67). Methods Pts in the study were randomized (1:1) to receive BV (1.2 mg/kg) or placebo every 3 weeks, in combination with R (375 mg/m2) and Len (20 mg) once daily. In these subgroup analyses, eligible pts had a BOR of CR and some ended study treatment and received any subsequent anticancer therapy. BOR was assessed by investigators according to the Lugano 2014 classification. Duration of response was defined as the time from the start of the first documented CR to the first documented tumor progression per Lugano 2014 or death. Pts who initiated a subsequent nonpalliative anticancer therapy were censored at the most recent prior response assessment. Subsequent nonpalliative anticancer therapies were defined as any systemic therapy received after the end of study treatment. P values are descriptive. Results Of the 112 pts in the BV+Len+R group, 45 (40.2%) had a BOR of CR. Of the 118 pts in the placebo+Len+R group, 22 (18.6%) had a BOR of CR. The median duration of CR was 18.9 months (95% CI, 11.1 months-not estimable [NE]) with BV+Len+R vs not reached (NR) with placebo+Len+R (hazard ratio [HR], 0.527; 95% CI, 0.200-1.389; P=.1891). The median time to CR was 1.58 months (range, 1.2-7.3 months) with BV+Len+R and 1.61 months (range, 0.7-4.6 months) with placebo+Len+R. With a median follow-up of 14.3 months, the median OS in pts with a BOR of CR was 31.5 months (95% CI, 20.3 months-NE) in the BV+Len+R group vs NR in the placebo+Len+R group (HR, 1.044; 95% CI, 0.331-3.298; P=.9407). Median PFS in pts with a BOR of CR was 21.5 months (95% CI, 12.6 months-NE) in the BV+Len+R group vs NR (95% CI, 5.4 months-NE) in the placebo+Len+R group (HR, 0.6333; 95% CI, 0.256-1.567; P=.3198). Results of NR in the placebo+Len+R group are likely attributable to limited follow-up and small sample size. Additional data on baseline characteristics of pts who had CR will be presented. Of the 45 pts with CR in the BV+Len+R group, 42 (93.3%) received no subsequent anticancer therapy. Of the 22 pts with CR in the placebo+Len+R group, 17 (77.3%) received no subsequent anticancer therapy. Conclusions BV doubled the CR rate in pts with R/R DLBCL compared with placebo, and outcomes in pts with CR were durable, with only 6.7% of pts treated with BV+Len+R receiving subsequent systemic anticancer therapy, compared with 22.7% of pts treated with placebo+Len+R receiving subsequent therapy. Overall, BV+Len+R demonstrated a survival benefit in the ECHELON-3 study and is a promising option to achieve complete and durable responses in third- or later-line therapy for pts with R/R DLBCL.
