Venous Thromboembolism Incidence and Risk Factors in Patients Undergoing Hematopoietic Stem Cell Transplantation.

Malignancy is a well-known risk factor for venous thromboembolism (VTE), and the Khorana risk score is effective for screening patients with solid tumors. However, there is a lack of validated screening tools and established risk factors for patients undergoing hematopoietic stem cell transplantation (HCT). Current literature reports a 2.

Cannabis Use and Cannabidiol Modulate HIV-Induced Alterations in TREM2 Expression: Implications for Age-Related Neuropathogenesis.

Triggering receptor expressed on myeloid cells 2 (TREM2) is involved in neuroinflammation and HIV-associated neurocognitive impairment (NCI). People with HIV (PWH) using cannabis exhibit lower inflammation and neurological disorders. We hypothesized that TREM2 dysfunction mediates HIV neuropathogenesis and can be reversed by cannabinoids.

Biologically Randomized Comparison of Haploidentical Versus Human Leukocyte Antigen-Matched Related Donor Reduced-Intensity Conditioning Hematopoietic Cell Transplantation.

Using haploidentical donors for allogeneic hematopoietic cell transplantation (HCT) broadens transplant accessibility to a growing number of patients with hematologic disorders. Moreover, haploidentical HCT with post-transplant cyclophosphamide (PTCy) has become widespread practice due to accumulating evidence demonstrating favorable rates of survival and graft-versus-host disease (GvHD). Most studies comparing outcomes by donor sources have been confounded by variability in conditioning regimens, graft type (peripheral blood [PB] or bone marrow), and post-transplant GvHD prophylaxis (PTCy or non-PTCy), making it difficult to define the effect of donor source on outcomes.

Real-World Analysis of Barriers to Timely Administration of Chimeric Antigen Receptor T Cell (CAR T) Therapy in Diffuse Large B-cell Lymphoma.

The implementation of chimeric antigen receptor T (CAR T) therapy in the real-world setting is hindered by logistical and financial barriers, impacting timely access to this life-saving treatment. Clinical trials have reported the time from leukapheresis to CAR T cell infusion (vein-to-vein time) but not the time from CAR T referral to infusion (decision-to-vein time). Herein, we report the barriers to CAR T therapy in a real-world setting.

Hereditary chronic neutrophilic leukemia in a four-generation family without transformation to acute leukemia.

Chronic neutrophilic leukemia (CNL) is a rare myeloproliferative neoplasm (MPN) characterized by peripheral blood neutrophilia, marrow granulocyte hyperplasia, hepatosplenomegaly, and driver mutations in the colony-stimulating factor 3 receptor (CSF3R). Designation of activating CSF3R mutations as a defining genomic abnormality for CNL has led to increased recognition of the disease. However, the natural history of CNL remains poorly understood with most patients reported being of older age, lacking germline data, and having poor survival, in part due to transformation to acute leukemia.

Prognostic significance of myeloid-derived suppressor cells and systemic inflammation in newly diagnosed diffuse large B cell lymphoma treated with chemoimmunotherapy.

The revised International Prognostic Index (R-IPI) is an important prognostic tool in diffuse large B cell lymphoma (DLBCL); however, outcomes can vary markedly within R-IPI groups, and additional prognostic markers are needed. We conducted a prospective observational study to evaluate the circulating immature myeloid (IM) cell subsets and cytokine profiles of 31 patients with newly diagnosed DLBCL before and after chemoimmunotherapy. Among circulating IM cells, myeloid-derived suppressor cells (MDSCs) were the predominant cell type (73.

Pharmacogenetic and clinical predictors of voriconazole concentration in hematopoietic stem cell transplant recipients receiving CYP2C19-guided dosing.

CYP2C19-guided voriconazole dosing reduces pharmacokinetic variability, but many patients remain subtherapeutic. The aim of this study was to evaluate the effect of candidate genes and a novel CYP2C haplotype on voriconazole trough concentrations in patients receiving CYP2C19-guided dosing. This is a retrospective candidate gene study in allogeneic hematopoietic cell transplant (HCT) patients receiving CYP2C19-guided voriconazole dosing.

A Sexually Dimorphic Role for Intestinal Cannabinoid Receptor Subtype-1 in the Behavioral Expression of Anxiety.

Increasing evidence suggests that the endocannabinoid system (ECS) in the brain controls anxiety and may be a therapeutic target for the treatment of anxiety disorders. For example, both pharmacological and genetic disruption of cannabinoid receptor subtype-1 (CBR) signaling in the central nervous system is associated with increased anxiety-like behaviors in rodents, while activating the system is anxiolytic. Sex is also a critical factor that controls the behavioral expression of anxiety; however, roles for the ECS in the gut in these processes and possible differences between sexes are largely unknown.

Increased body weight in mice with fragile X messenger ribonucleoprotein 1 (Fmr1) gene mutation is associated with hypothalamic dysfunction.

Mutations in the Fragile X Messenger Ribonucleoprotein 1 (FMR1) gene are linked to Fragile X Syndrome, the most common monogenic cause of intellectual disability and autism. People affected with mutations in FMR1 have higher incidence of obesity, but the mechanisms are largely unknown. In the current study, we determined that male Fmr1 knockout mice (KO, Fmr1), but not female Fmr1, exhibit increased weight when compared to wild-type controls, similarly to humans with FMR1 mutations.

Discursive, Communal, and Individual Coping Strategies: How U.S. Adults Co-constructed Coping During Preliminary COVID-19 Stressors.

This interpretive research study explores U.S. adults' lived experiences during the beginning months of the COVID-19 global pandemic.

UPLC-MS/MS Method for Analysis of Endocannabinoid and Related Lipid Metabolism in Mouse Mucosal Tissue.

The endocannabinoid system is expressed in cells throughout the body and controls a variety of physiological and pathophysiological functions. We describe robust and reproducible UPLC-MS/MS-based methods for analyzing metabolism of the endocannabinoids, 2-arachidonoyl--glycerol and arachidonoyl ethanolamide, and related monoacylglycerols (MAGs) and fatty acid ethanolamides (FAEs), respectively, in mouse mucosal tissues (i.e.

Equal access to care and nurse navigation leads to equitable outcomes for minorities with aggressive large B-cell lymphoma.

Background: Aggressive large B-cell lymphomas (LBCLs) are curable, but previous studies have shown inferior outcomes in minorities. Nurse navigation programs can improve patient outcomes by providing patient support. This study presents the outcomes of White and minority patients with aggressive LBCL at an institution with an active nurse navigation program.

Collective Emotion During Collective Trauma: A Metaphor Analysis of the COVID-19 Pandemic.

This study provides insight into lived experiences of the COVID-19 pandemic in the United States. Participant metaphors of the pandemic were collected by conducting in-depth semi-structured interviews ( = 44). Participants were asked to compare the pandemic with an animal and with a color, and to provide contextual sensemaking about their metaphors.

Cost saving, patient centered algorithm for progenitor cell mobilization for autologous hematopoietic cell transplantation.

Administration of plerixafor with granulocyte-colony stimulating factor (G-CSF) mobilizes CD34+ cells much more effectively than G-CSF alone, but cost generally limits plerixafor use to patients at high risk of insufficient CD34+ cell collection based on low peripheral blood (PB) CD34+ counts following 4 days of G-CSF. We analyzed costs associated with administering plerixafor to patients with higher day 4 CD34+ cell counts to decrease apheresis days and explored the use of a fixed split dose of plerixafor instead of weight-based dosing. We analyzed 235 patients with plasma cell disorders or non-Hodgkin's lymphoma who underwent progenitor cell mobilization and autologous hematopoietic cell transplantation (AHCT) between March 2014 and December 2017.

Heterozygous germ line CSF3R variants as risk alleles for development of hematologic malignancies.

Colony-stimulating factor 3 receptor (CSF3R) encodes the receptor for granulocyte colony-stimulating factor (G-CSF), a cytokine vital for granulocyte proliferation and differentiation. Acquired activating heterozygous variants in CSF3R are the main cause of chronic neutrophilic leukemia, a hyperproliferative disorder. In contrast, biallelic germ line hypomorphic variants in CSF3R are a rare cause of severe congenital neutropenia, a hypoproliferative condition.

Momentary task-values and expectations predict engagement in science among Finnish and Chilean secondary school students.

While expectancy-value-cost theory predicts that students' task values play an important part in academic engagement, these associations have rarely been tested in science education and are even less studied in authentic classroom situations. The present study examined to what extent momentary task-values, expectations and costs are associated with students' momentary academic engagement in science classes. Momentary academic engagement was operationalised as energy (give up), dedication (grit) and absorption (flow) components of engagement.

Cannabinoid CB Receptors in the Intestinal Epithelium Are Required for Acute Western-Diet Preferences in Mice.

The endocannabinoid system plays an important role in the intake of palatable food. For example, endocannabinoid signaling in the upper small-intestinal epithelium is increased (i) in rats after tasting dietary fats, which promotes intake of fats, and (ii) in a mouse model of diet-induced obesity, which promotes overeating via impaired nutrient-induced gut-brain satiation signaling. We now utilized a combination of genetic, pharmacological, and behavioral approaches to identify roles for cannabinoid CBRs in upper small-intestinal epithelium in preferences for a western-style diet (WD, high-fat/sucrose) versus a standard rodent diet (SD, low-fat/no sucrose).

Survival following allogeneic transplant in patients with myelofibrosis.

Allogeneic hematopoietic cell transplantation (HCT) is the only curative therapy for myelofibrosis (MF). In this large multicenter retrospective study, overall survival (OS) in MF patients treated with allogeneic HCT (551 patients) and without HCT (non-HCT) (1377 patients) was analyzed with Cox proportional hazards model. Survival analysis stratified by the Dynamic International Prognostic Scoring System (DIPSS) revealed that the first year of treatment arm assignment, due to upfront risk of transplant-related mortality (TRM), HCT was associated with inferior OS compared with non-HCT (non-HCT vs HCT: DIPSS intermediate 1 [Int-1]: hazard ratio [HR] = 0.
