ABSTRACT Background The second consensus criteria for the diagnosis of multiple system atrophy (MSA) are widely recognized as the reference standard for clinical research, but lack sensitivity to diagnose the disease at early stages. Objective To develop novel Movement Disorder Society (MDS) criteria for MSA diagnosis using an evidence‐based and consensus‐based methodology. Methods We identified shortcomings of the second consensus criteria for MSA diagnosis and conducted a systematic literature review to answer predefined questions on clinical presentation and diagnostic tools relevant for MSA diagnosis. The criteria were developed and later optimized using two Delphi rounds within the MSA Criteria Revision Task Force, a survey for MDS membership, and a virtual Consensus Conference. Results The criteria for neuropathologically established MSA remain unchanged. For a clinical MSA diagnosis a new category of clinically established MSA is introduced, aiming for maximum specificity with acceptable sensitivity. A category of clinically probable MSA is defined to enhance sensitivity while maintaining specificity. A research category of possible prodromal MSA is designed to capture patients in the earliest stages when symptoms and signs are present, but do not meet the threshold for clinically established or clinically probable MSA. Brain magnetic resonance imaging markers suggestive of MSA are required for the diagnosis of clinically established MSA. The number of research biomarkers that support all clinical diagnostic categories will likely grow. Conclusions This set of MDS MSA diagnostic criteria aims at improving the diagnostic accuracy, particularly in early disease stages. It requires validation in a prospective clinical and a clinicopathological study. © 2022 The Authors.

Introduction Insulin resistance (IR) plays a key role in the pathogenesis and clinical course of patients with multiple metabolic diseases and diabetes. This study aimed to explore the effect of trimetazidine (TMZ) on skeletal muscle IR in mice fed a high-fat diet (HFD) and explore the possible underlying mechanism. Research design and methods In vivo, a HFD mouse IR model was adopted and TMZ and exercise were used to intervene. Postintervention the following were determined: blood levels of glucose and insulin, homeostasis model assessment of IR index, expression of skeletal muscle insulin signaling-related proteins phosphorylated insulin receptor substrate 1 (p-IRS1/IRS1) and phosphorylated protein kinase B (p-AKT/AKT), nuclear factor erythroid 2 related factor 2 (Nrf2) signaling pathway, and oxidative stress. In vitro, a palmitate-treated C2C12 myotube IR model was constructed. Cellular glucose uptake, p-IRS1/IRS1, and p-AKT/AKT were determined, and reactive oxygen species (ROS) production was analyzed based on treatments with specific small interfering RNA of Nrf2 with or without TMZ. Western blot was used to obtain the protein expression level and ROS production by functional analysis kits. Results In vivo, TMZ and exercise decreased the blood glucose and insulin levels and homeostasis model assessment of IR index, increased skeletal muscle insulin signaling-related protein ratios of p-IRS1/IRS1 and p-AKT/AKT, and both interventions activated Nrf2 signaling and reduced oxidative stress production in HFD mice. In vitro, TMZ reduced the oxidative stress reaction, increased the ratios of p-AKT/AKT and p-IRS1/IRS1, and attenuated the insulin stimulation of PA-induced glucose uptake. However, in the absence of Nrf2, TMZ failed to resist the effects of IR. Conclusions This study showed that TMZ, like exercise, brought about marked improvements to HFD-induced skeletal muscle IR through TMZ, a common pathway with exercise in the form of Nrf2, regulating oxidative stress. We provide new evidence to support the use of TMZ for diabetes treatment.

Background In participants with concomitant chronic coronary disease and advanced chronic kidney disease (CKD), the effect of treatment strategies on the timing of dialysis initiation is not well characterized. Methods and Results In ISCHEMIA‐CKD (International Study of Comparative Health Effectiveness With Medical and Invasive Approaches–Chronic Kidney Disease), 777 participants with advanced CKD and moderate or severe ischemia were randomized to either an initial invasive or conservative management strategy. Herein, we compare the proportion of randomized participants with non–dialysis‐requiring CKD at baseline (n=362) who initiated dialysis and compare the time to dialysis initiation between invasive versus conservative management arms. Using multivariable Cox regression analysis, we also sought to identify the effect of invasive versus conservative chronic coronary disease management strategies on dialysis initiation. At a median follow‐up of 23 months (25th–75th interquartile range, 14–32 months), dialysis was initiated in 18.9% of participants (36/190) in the invasive strategy and 16.9% of participants (29/172) in the conservative strategy (P= 0.22). The median time to dialysis initiation was 6.0 months (interquartile range, 3.0–16.0 months) in the invasive group and 18.2 months (interquartile range, 12.2–25.0 months) in the conservative group (P= 0.004), with no difference in procedural acute kidney injury rates between the groups (7.8% versus 5.4%; P =0.26). Baseline clinical factors associated with earlier dialysis initiation were lower baseline estimated glomerular filtration rate (hazard ratio [HR] associated with 5‐unit decrease, 2.08 [95% CI, 1.72–2.56]; P <0.001), diabetes (HR, 2.30 [95% CI, 1.28–4.13]; P =0.005), hypertension (HR, 7.97 [95% CI, 1.09–58.21]; P =0.041), and Hispanic ethnicity (HR, 2.34 [95% CI, 1.22–4.47]; P =0.010). Conclusions In participants with non–dialysis‐requiring CKD in ISCHEMIA‐CKD, randomization to an invasive chronic coronary disease management strategy (relative to a conservative chronic coronary disease management strategy) is associated with an accelerated time to initiation of maintenance dialysis for kidney failure.

Abstract Background: Quality of life (QOL) in breast cancer patients (pts) can be greatly impacted by initial treatment and ongoing therapy, particularly if side effects and symptoms are not well tolerated. The PALLAS trial investigated whether the addition of 2 years of palbociclib (palbo) to adjuvant endocrine therapy (ET) improved invasive disease-free survival (iDFS) over adjuvant ET alone. We report on the main patient-reported outcome (PRO) quality of life (QOL) and symptom severity results of this trial by treatment arm. Methods: PALLAS is an ongoing multicenter, open label phase 3 trial that enrolled hormone receptor positive, HER2-negative, stage II-III breast cancer patients at 406 cancer centers across 21 countries. Patients were randomly assigned (1:1) to either 2 years of palbo (125mg/day, 3 weeks on 1 week off) plus ongoing provider or patient-choice adjuvant ET (palbo+ET) versus ongoing ET alone. The primary study endpoint was iDFS. Treatment with palbo in all pts stopped at the time of the second interim analysis (5/2020) due to futility; all pts then moved to follow up. The PRO analyses were triggered for completion after awareness of the pre-specified 469 iDFS cases in November 2020. Eight PRO endpoints were measured serially (i.e., day 1 of each monthly cycle for the first 3 months, then every 3 months for the first 2 years, and once at year 3). The endpoints were the EORTC QLQ-C30 global health status/QOL score, the Brief Fatigue Inventory score, the modified Brief Pain Inventory severity and pain interference scores, the EORTC QLQ-BR23 alopecia score, and the Breast Cancer Prevention Trial hot flash symptoms, vaginal problems, and musculoskeletal pain scores. Linear mixed models compared the average difference between arms across time points during the initial 2-year treatment period adjusting for cycle 1 day 1 (C1D1) PRO scores, demographic and clinical variables. The average differences between arms (palbo+ET vs ET alone) and the two-sided (1-[0.05/8]) x 100% confidence intervals, adjusted for multiple comparisons, were calculated. Analysis of covariance compared the average between-arm differences by endpoint at 3 years. Results: The PRO intention to collect population included 4688 (81%) of the overall trial pts, and was clinically and demographically representative of the remaining 1073 pts. Each analysis population, with measures at C1D1 and at least 1 post-C1D1 assessment for each PRO endpoint, comprised ≥ 89% of the 4688 pts and the proportions were similar between arms. After adjustment for baseline covariates, on average, no clinically important differences between arms were observed for any of the eight endpoints over the 2 year treatment period (Table 1). All effect sizes were below the pre-specified 0.2 threshold. These PRO results were similar at the 3 year time point. Conclusions: No clinically significant differences in either patient-reported QOL or symptom severity were found, on average, between participants in the two PALLAS treatment arms while either taking palbo+ET or ET alone, or after study-wide termination of palbo. In general, the addition of palbociclib in the adjuvant breast cancer setting did not contribute to increased symptom burden within this survivorship population. Further analyses will examine the relationship between PROs and treatment discontinuation by arm and study time point.

Abstract Stroke represents a considerable burden of disease for both men and women. However, a growing body of literature suggests clinically relevant sex differences in the underlying causes, presentations and outcomes of acute ischaemic stroke. In a recent study, we reported sex divergences in lesion topographies: specific to women, acute stroke severity was linked to lesions in the left-hemispheric posterior circulation. We here determined whether these sex-specific brain manifestations also affect long-term outcomes. We relied on 822 acute ischaemic patients [age: 64.7 (15.0) years, 39% women] originating from the multi-centre MRI-GENIE study to model unfavourable outcomes (modified Rankin Scale &gt;2) based on acute neuroimaging data in a Bayesian hierarchical framework. Lesions encompassing bilateral subcortical nuclei and left-lateralized regions in proximity to the insula explained outcomes across men and women (area under the curve = 0.81). A pattern of left-hemispheric posterior circulation brain regions, combining left hippocampus, precuneus, fusiform and lingual gyrus, occipital pole and latero-occipital cortex, showed a substantially higher relevance in explaining functional outcomes in women compared to men [mean difference of Bayesian posterior distributions (men – women) = −0.295 (90% highest posterior density interval = −0.556 to −0.068)]. Once validated in prospective studies, our findings may motivate a sex-specific approach to clinical stroke management and hold the promise of enhancing outcomes on a population level.

Abstract Idasanutlin, an MDM2 antagonist, showed clinical activity and a rapid reduction in JAK2 V617F allele burden in patients with polycythemia vera (PV) in a phase 1 study. This open-label phase 2 study evaluated idasanutlin in patients with hydroxyurea (HU)-resistant/-intolerant PV, per the European LeukemiaNet criteria, and phlebotomy dependence; prior ruxolitinib exposure was permitted. Idasanutlin was administered once daily on days 1 through 5 of each 28-day cycle. The primary end point was composite response (hematocrit control and spleen volume reduction &gt; 35%) in patients with splenomegaly and hematocrit control in patients without splenomegaly at week 32. Key secondary end points included safety, complete hematologic response (CHR), patient-reported outcomes, and molecular responses. All patients (n = 27) received idasanutlin; 16 had response assessment (week 32). Among responders with baseline splenomegaly (n = 13), 9 (69%) attained any spleen volume reduction, and 1 achieved composite response. Nine patients (56%) achieved hematocrit control, and 8 patients (50%) achieved CHR. Overall, 43% of evaluable patients (6/14) showed a ≥50% reduction in the Myeloproliferative Neoplasm Symptom Assessment Form Total Symptom Score (week 32). Nausea (93%), diarrhea (78%), and vomiting (41%) were the most common adverse events, with grade ≥ 3 nausea or vomiting experienced by 3 patients (11%) and 1 patient (4%), respectively. Reduced JAK2 V617F allele burden occurred early (after 3 cycles), with a median reduction of 76%, and was associated with achieving CHR and hematocrit control. Overall, the idasanutlin dosing regimen showed clinical activity and rapidly reduced JAK2 allele burden in patients with HU-resistant/- intolerant PV but was associated with low-grade gastrointestinal toxicity, leading to poor long-term tolerability. This trial was registered at www.clinincaltrials.gov as #NCT03287245.

The NCCN Guidelines for Squamous Cell Skin Cancer provide recommendations for diagnostic workup, clinical stage, and treatment options for patients with cutaneous squamous cell carcinoma. The NCCN panel meets annually to discuss updates to the guidelines based on comments from panel members and the Institutional Review, as well as submissions from within NCCN and external organizations. These NCCN Guidelines Insights focus on the introduction of a new surgical recommendation terminology (peripheral and deep en face margin assessment), as well as recent updates on topical prophylaxis, immunotherapy for regional and metastatic disease, and radiation therapy.

Abstract Background: Pts with previously treated R/R aggressive LBCL have compromised health-related QOL (HRQOL). Liso-cel is an autologous, CD19-directed, defined composition, 4-1BB CAR T cell product administered at equal target doses of CD8 + and CD4 + CAR + T cells. In a prespecified interim analysis of TRANSFORM (NCT03575351), a randomized, open-label, pivotal trial, liso-cel demonstrated statistically significant and clinically meaningful improvement in the primary endpoint of event-free survival and key secondary endpoints (complete response rate and progression-free survival) in adults with R/R LBCL after failure of first-line (1L) immunochemotherapy compared with SOC, with no new safety signals. Here we present results of the pt-reported outcomes (PRO) analysis from TRANSFORM. Methods: Adults (age ≤ 75 yrs) with R/R LBCL (≤ 12 mo after 1L therapy), who were eligible for autologous stem cell transplantation (ASCT), were randomized to receive either SOC (3 cycles of salvage chemotherapy [CT] and BEAM + ASCT for responding pts) or liso-cel after lymphodepletion. Crossover to receive liso-cel was allowed in the SOC arm for pts who failed treatment. The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire - 30 items (EORTC QLQ-C30) and the Functional Assessment of Cancer Therapy - Lymphoma Subscale (FACT-LymS) were administered at randomization (baseline) and on Days 29 (infusion of liso-cel or 2 cycles of salvage CT), 64 (1 mo post liso-cel or completion of CT), 126 (3 mos post liso-cel or 2 mos post ASCT), and Mo 6 and other prespecified timepoints up to Mo 36 or end of study. No PRO data were collected after crossover. The analysis was based on the PRO-evaluable population (pts with a baseline and ≥ 1 post-baseline assessment). Predefined thresholds determined clinically meaningful changes. Global health/QOL (GH/QOL), physical functioning, cognitive functioning, fatigue, pain, and FACT-LymS were the primary domains of interest based on their relevance to the study population and treatment. A linear mixed model for repeated measures (MMRM) analysis was performed to assess the between-treatment difference in overall least squares (LS) mean change from baseline for each primary domain, using data collected up to Day 126 for visits with a sample size per arm ≥ 10. Proportions of pts with meaningful change from baseline were assessed for each primary domain up to Mo 6. All analyses were descriptive only. Results: Of 184 randomized pts, 90 (49%) and 85 (46%), respectively, were included in the PRO-evaluable population for the EORTC QLQ-C30 (SOC vs liso-cel n=43 vs 47) and FACT-LymS (n=40 vs 45, respectively). The PRO assessment completion rate from baseline up to Mo 6 was ≥ 45%, which was lower than expected primarily due to operational challenges during the COVID-19 pandemic but was comparable for both arms. In the MMRM analysis, the liso-cel arm had more favorable overall LS mean changes from baseline to Day 126 than the SOC arm in most of the EORTC QLQ-C30 domains and FACT-LymS. In particular, the between-treatment differences for cognitive functioning (−2.09 vs 2.21) and fatigue (3.75 vs −1.95) for SOC versus liso-cel, respectively, exceeded the prespecified minimal important difference threshold (Table); in those domains, the SOC arm deteriorated while the liso-cel arm improved. In individual-level analyses, the proportion of pts with meaningful improvement for fatigue and GH/QOL was higher, while deterioration was lower, in the liso-cel arm versus SOC arm from baseline up to Mo 6 (Figure). At Mo 6, a higher proportion of pts experienced worsened fatigue (71% vs 18%) and a lower proportion experienced improved fatigue (29% vs 47%) in the SOC arm compared with the liso-cel arm; for GH/QOL, a higher proportion of pts worsened (57% vs 18%) and lower proportion improved (14% vs 53%), respectively. For the other primary domains, the proportions of pts with improvement or deterioration favored liso-cel or were similar between arms. Conclusions: Compared with SOC, liso-cel showed favorable improvement in most primary PRO domains, particularly EORTC QLQ-C30 cognitive functioning and fatigue and more pts showed PRO improvements and fewer showed deterioration by Mo 6 with liso-cel. The results were achieved despite only responders remaining in the SOC arm after salvage CT. HRQOL was either improved or maintained after liso-cel treatment in pts with R/R LBCL after failure of 1L therapy. Figure 1 Figure 1.

Histiocytic neoplasms are rare hematologic disorders accounting for less than 1% of cancers of the soft tissue and lymph nodes. Clinical presentation and prognosis of these disorders can be highly variable, leading to challenges for diagnosis and optimal management of these patients. Treatment often consists of systemic therapy, and recent studies support use of targeted therapies for patients with these disorders. Observation (“watch and wait”) may be sufficient for select patients with mild disease. These NCCN Guidelines for Histiocytic Neoplasms include recommendations for diagnosis and treatment of adults with the most common histiocytic disorders: Langerhans cell histiocytosis, Erdheim-Chester disease, and Rosai-Dorfman disease.
