Introduction: NPM1-mutated (NPM1mut) myeloid neoplasms (MNs) with < 20% bone marrow (BM) blasts (NPM1mut MNs< 20) are uncommon, and their classification remains inconsistent.
Methods: The clinicopathologic features of 54 patients with NPM1mut MNs < 20 were evaluated and compared with wild-type NPM1 MNs < 20 and NPM1mut MNs≥20, respectively.
Results: NPM1mut MNs had similar features regardless of blast percentage, except for higher IDH2 (29% vs 7%, p = .023) and FLT3 (70% vs 11%, p < .001) frequency in patients with ≥20% BM blasts. Thirty-three (61%) patients with NPM1mut MNs < 20 received low-intensity chemotherapy (LIC) and 12 (22%) received intensive chemotherapy (IC). Higher complete remission rates (75% vs 27%, p = .006) and median overall survival (mOS) (not reached vs 30.4 months, p = .06) were observed with IC compared to LIC. Young patients (age < 60 years) did not reach mOS either when treated with LIC or IC. Stem cell transplant was associated with increased survival only in patients treated with LIC (HR, 0.24; p = .025). No differences in mOS were observed by BM blast strata (32.2 months, not reached and 46.9 months for < 10%, 10%-19%, and ≥20% blasts, p = .700) regardless of treatment modality (LIC: p = .900; IC: p = .360). Twenty-three patients (43%) with NPM1mut MNs < 20 had marrow blast progression to ≥20%.
Conclusions: Overall, NPM1mut MNs define a unique entity independent of BM blast percentage.

Biallelic loss of cyclin-dependent kinase 12 (CDK12) defines a metastatic castration-resistant prostate cancer (mCRPC) subtype. It remains unclear, however, whether CDK12 loss drives prostate cancer (PCa) development or uncovers pharmacologic vulnerabilities. Here, we show Cdk12 ablation in murine prostate epithelium is sufficient to induce preneoplastic lesions with lymphocytic infiltration. In allograft-based CRISPR screening, Cdk12 loss associates positively with Trp53 inactivation but negatively with Pten inactivation. Moreover, concurrent Cdk12/Trp53 ablation promotes proliferation of prostate-derived organoids, while Cdk12 knockout in Pten-null mice abrogates prostate tumor growth. In syngeneic systems, Cdk12/Trp53-null allografts exhibit luminal morphology and immune checkpoint blockade sensitivity. Mechanistically, Cdk12 inactivation …

ATP-grasp superfamily enzymes contain a hand-like ATP-binding fold and catalyze a variety of reactions using a similar catalytic mechanism. More than 30 protein families are categorized in this superfamily, and they are involved in a plethora of cellular processes and human diseases. Here, we identify C12orf29 (RLIG1) as an atypical ATP-grasp enzyme that ligates RNA. Human RLIG1 and its homologs autoadenylate on an active site Lys residue as part of a reaction intermediate that specifically ligates RNA halves containing a 5’-phosphate and a 3’-hydroxyl. RLIG1 binds tRNA in cells and can ligate tRNA within the anticodon loop in vitro. Transcriptomic …

We develop a machine learning (ML) model using electrocardiography (ECG) to predict myocardial blood flow reserve (MFR) and assess its prognostic value for major adverse cardiovascular events (MACEs). Using 3,639 ECG-positron emission tomography (PET) and 17,649 ECG-single-photon emission computed tomography (SPECT) data pairs, the ML model is trained with a swarm intelligence approach and support vector regression (SVR). The model achieves a receiver-operator curve (ROC) area under the curve (AUC) of 0.83, with a sensitivity and specificity of 0.75. An ECG-MFR value below 2 is significantly associated with MACE, with hazard ratios (HRs) of 3.85 and 3.70 in the discovery …

Purpose: Large cell neuroendocrine carcinoma (LCNEC) is a high-grade neuroendocrine malignancy that, like small cell lung cancer (SCLC), is associated with the absence of druggable oncogenic drivers and dismal prognosis. In contrast to SCLC, however, there is little evidence to guide optimal treatment strategies, which are often adapted from SCLC and non-small cell lung cancer approaches.
Experimental design: To better define the biology of LCNEC, we analyzed cell line and patient genomic data and performed IHC and single-cell RNA sequencing of core needle biopsies from patients with LCNEC and preclinical models.
Results: In this study, we demonstrate that the presence …

Single-cell RNA sequencing is a powerful tool to investigate the cellular makeup of tumor samples. However, due to the sparse data and the complex tumor microenvironment, it can be challenging to identify neoplastic cells that play important roles in tumor growth and disease progression. This is especially relevant for blood cancers, where neoplastic cells may be highly similar to normal cells. To address this challenge, we have developed partCNV and partCNVH, two methods for rapid and accurate detection of aneuploid cells with local copy number deletion or amplification. PartCNV uses an expectation-maximization (EM) algorithm with mixtures of Poisson distributions and …

Purpose: Survival analyses of novel agents with long-term responders often exhibit differential hazard rates over time. Such proportional hazards violations (PHV) may reduce the power of the log-rank test and lead to misinterpretation of trial results. We aimed to characterize the incidence and study attributes associated with PHVs in phase III oncology trials and assess the utility of restricted mean survival time and maximum combination test as additional analyses.
Experimental design: Clinicaltrials.gov and PubMed were searched to identify two-arm, randomized, phase III superiority-design cancer trials with time-to-event primary endpoints and published results through 2020. Patient-level data were reconstructed from published …

Ice wedges / pseudomorphs (IWPs) are key indicators of cold-climate (periglacial) frozen ground conditions. Their occurrence within the sedimentary sequences of lacustrine landforms can provide important evidence about palaeoenvironmental and palaeoclimatic change. However, research using lake sediments in a geomorphological context to investigate climate change is limited. Here, we use newly discovered IWPs developed within lake sediment sequences to explore climate-related lake-level fluctuations in the Dali Lake region, a key area of the East Asian summer monsoon (EASM) system that drives Quaternary hydroclimate variability across East Asia. The IWPs penetrate down through clay-silt lake sediments and are overlain by coarser-fossiliferous, …

Cardiac cellular fate transition holds remarkable promise for the treatment of ischemic heart disease. We report that overexpressing two transcription factors, Sall4 and Gata4, which play distinct and overlapping roles in both pluripotent stem cell reprogramming and embryonic heart development, induces a fraction of stem-like cells in rodent cardiac fibroblasts that exhibit unlimited ex vivo expandability with clonogenicity. Transcriptomic and phenotypic analyses reveal that around 32 ± 6.4% of the expanding cells express Nkx2.5, while 13 ± 3.6% express Oct4. Activated signaling pathways like PI3K/Akt, Hippo, Wnt, and multiple epigenetic modification enzymes are also detected. Under suitable conditions, these cells …

A novel method for creating “golden” 3D center-out radial MRI sampling trajectories was developed and analyzed. This method, called ELECTRO (ELECTRic potential energy Optimized), uses repulsive forces to minimize electric potential energy. An objective function , the electric potential energies of all subsets of consecutive readouts in a 3D radial trajectory, and its reduced form were minimized using a multi-stage optimization strategy. A metric called normalized mean nearest neighbor angular distance (NMNA) was proposed for describing distributions of points on a sphere. ELECTRO and other relevant golden trajectories were compared in silico using NMNA and point spread function analysis. Consecutive …

EN 196-1 states that the compressive strength result of testing of standard mortar specimens corresponds to the average of the six individual measurements. If one of the six individual measurements varies more than ±10 % from the average, it must be excluded, and a new average is calculated with the five remaining values. This methodology might be interesting for quality control or characterization of cement; however, it may not be the best approach for research or scientific purposes. Applying EN 196-1 to non-standard cement-based mortars with multiple and even unconventional supplementary cementitious materials may induce even more variation in the …

Pre-clinical murine and in vitro models have demonstrated that exercise suppresses tumour and cancer cell growth. These anti-oncogenic effects of exercise were associated with the exercise-mediated release of myokines such as interleukin (IL)-15. However, no study has quantified the acute IL-15 response in human cancer survivors, and whether physiological adaptations to exercise training (i.e. body composition and cardiorespiratory fitness) influence this response. In the present study breast, prostate and colorectal cancer survivors (n = 14) completed a single bout of high-intensity interval exercise (HIIE) [4×4 min at 85–95% heart rate (HR) peak, 3 min at 50–70% HR peak] before and …

Introduction: The adverse effects of social isolation and loneliness (SI/L) have been documented among older adults in rural communities and contribute to poor health outcomes, premature disability and mortality, and increased burden on the healthcare system. The identification of factors contributing to SI/L among older adults can build the foundation for rural policymakers and leaders to allocate resources and develop tailored strategies more efficiently. The purpose of this article is to describe findings from a needs assessment designed to understand local factors that contribute to SI/L among rural older adults in a county in Northeast Tennessee. Findings from the needs …

Purpose: Barriers to communication and inaccurate provider assumptions about patient priorities limit the delivery of comprehensive, high-quality, patient-centered care (PCC) to people with Parkinson’s (PWP). This study aimed to analyze priorities of PWP using a qualitative, unstructured single-question survey and to test associations with validated quality of life (QOL) measures.
Methods: During appointments at a subspecialty, interdisciplinary clinic, PWP (n = 139) provided written responses to the prompt: “What is important for your care team to know about you?” Patient Health Questionnaire, Montreal Cognitive Assessment, and Hoehn and Yahr scales were obtained through retrospective chart review. Key qualitative themes were …

Levan had been extracted, purified, and characterized from Lactobacillus gasseri. Levan characterization had been carried out using "thin-layer chromatography (TLC)", 1HNuclear-MagneticsResonances (HNMR), and Fouriere-transforms infrared spectroscopies (FTIR). Characterization demonstrated that pure levan is a homopolysaccharide with just fructose and atypical for carbohydrate bond area of 868 cm-1. The maximum water solubility index (WSI) percentage was 90% at a conc. of 100 mg/5 ml, while the highest water holding capacity value had been 252 at a conc. of 50 mg/5 ml. The wound dressings were prepared using purified levan from L.gasseri and its blend with polyvinyl alcohol (PVA) polymer, and the …

People with disabilities experience inequitable exposure to social determinants of health (SDOH) that contribute to disparate health outcomes, including psychological distress. There is little research examining which SDOH have the strongest effect on psychological distress among people with disabilities. This leaves healthcare providers and policy makers with insufficient information to make well-informed treatment decisions or allocate resources effectively. We explored the association between SDOH and disability and which factors may moderate the association between disability and psychological distress. Using data from the US Census Bureau's Household Pulse Survey (Phase 3.5), we examined SDOH among people with and without disability (

Anthropogenic Impacts On Aquatic Organisms, Alexis Khursigara
Sustainability Seminar Series
Aquatic environments are often dynamic, experiencing shifts in a multitude of anthropogenic stressors related to climate change and contaminant loads. Aquatic organisms, such as fish and invertebrates, must cope with these changes that can be rapid or gradual, acute or chronic, and often co-occurring. Understanding how well aquatic organisms tolerate these shifts is imperative for management practices. In this presentation, Dr. Khursigara will discuss how different anthropogenic stressors alter the physiology and behavior of multiple fish and aquatic invertebrate species.
