Laryngeal and oropharyngeal adenocarcinoma with pulmonary metastases in a common raven (Corvus corax).

A captive 15-year-old male common raven () was presented for post-mortem examination. It had been previously presented to a local veterinarian due to a 3-4 weeks long history of abnormal respiratory sounds. Upon admission, the bird demonstrated severe dyspnea and a massive amount of mucous in the oropharynx.

Low-cost PM sensors can help identify driving factors of poor air quality and benefit communities.

Air quality is critical for public health. Residents rely chiefly on government agencies such as the Environmental Protection Agency (EPA) in the United States to establish standards for the measurement of harmful contaminants including ozone, sulfur dioxide, carbon monoxide, volatile organic chemicals (VOCs), and fine particulate matter at or below 2.5 μm.

Bendamustine/Rituximab Plus Cytarabine/Rituximab, With or Without Acalabrutinib, for the Initial Treatment of Transplant-Eligible Mantle Cell Lymphoma Patients: Pooled Data From Two Pilot Studies.

Introduction: Mantle cell lymphoma (MCL) is a moderately aggressive lymphoma subtype, generally viewed as incurable. For younger, fit patients, the standard of care remains various high-dose cytarabine-based induction regimens followed by autologous hematopoietic cell transplant and 3 years of rituximab maintenance. Despite reasonably good outcomes, with median progression-free survival in the range of 7 to 9 years, most patients eventually relapse, indicating a need to improve the safety and tolerability of remission induction strategies.

Phospholipid Profiles for Phenotypic Characterization of Adipose-Derived Multipotent Mesenchymal Stromal Cells.

Multipotent mesenchymal stromal cells (MSC) have emerged as therapeutic tools for a wide range of pathological conditions. Yet, the still existing deficits regarding MSC phenotype characterization and the resulting heterogeneity of MSC used in different preclinical and clinical studies hamper the translational success. In search for novel MSC characterization approaches to complement the traditional trilineage differentiation and immunophenotyping assays reliably across species and culture conditions, this study explored the applicability of lipid phenotyping for MSC characterization and discrimination.

A phase I trial evaluating the effects of plerixafor, G-CSF, and azacitidine for the treatment of myelodysplastic syndromes.

Interactions between the bone marrow microenvironment and MDS tumor clones play a role in pathogenesis and response to treatment. We hypothesized G-CSF and plerixafor may enhance sensitivity to azacitidine in MDS. Twenty-eight patients with MDS were treated with plerixafor, G-CSF and azacitidine with a standard 3 + 3 design.

Engraftment of rare, pathogenic donor hematopoietic mutations in unrelated hematopoietic stem cell transplantation.

Clonal hematopoiesis is associated with various age-related morbidities. Error-corrected sequencing (ECS) of human blood samples, with a limit of detection of ≥0.0001, has demonstrated that nearly every healthy individual >50 years old harbors rare hematopoietic clones below the detection limit of standard high-throughput sequencing.

Diffusion basis spectrum imaging provides insights into MS pathology.

Objective: To use diffusion basis spectrum imaging (DBSI) to assess how damage to normal-appearing white matter (NAWM) in the corpus callosum (CC) influences neurologic impairment in people with MS (pwMS).

Methods: Using standard MRI, the primary pathologies in MS of axonal injury/loss, demyelination, and inflammation are not differentiated well. DBSI has been shown in animal models, phantoms, and in biopsied and autopsied human CNS tissues to distinguish these pathologies.

Cutaneous graft-versus-host disease incidence is similar in haploidentical and matched unrelated hematopoietic transplant recipients: A retrospective cohort study.

Background: Cutaneous graft-versus-host disease (GVHD) is common after hematopoietic cell transplants. Haploidentical transplants (Haplo) have historically higher rates of GVHD with overall outcomes improved with the use of posttransplant cyclophosphamide. Specific cutaneous outcomes have not been explored in haploidentical versus matched unrelated donor (MUD) transplants.

Implication of Rituximab Infusion Reactions on Clinical Outcomes in Patients With Diffuse Large B-cell Lymphoma: A Single Institution Experience.

Background: The addition of the anti-CD20 monoclonal antibody rituximab to chemotherapy for diffuse large B-cell lymphoma (DLBCL) has led to improvements in progression-free survival and overall survival, although the exact mechanism of rituximab is not known. Rituximab administration often results in transient, non-life-threatening infusion reactions (IRs). We report a retrospective cohort of patients with DLBCL who received rituximab to determine the significance of IRs on clinical outcomes.

Diffusion basis spectrum imaging for identifying pathologies in MS subtypes.

Diffusion basis spectrum imaging (DBSI) combines discrete anisotropic diffusion tensors and the spectrum of isotropic diffusion tensors to model the underlying multiple sclerosis (MS) pathologies. We used clinical MS subtypes as a surrogate of underlying pathologies to assess DBSI as a biomarker of pathology in 55 individuals with MS. Restricted isotropic fraction (reflecting cellularity) and fiber fraction (representing apparent axonal density) were the most important DBSI metrics to classify MS using brain white matter lesions.

Prevalence of Ototoxicity Following Hematopoietic Stem Cell Transplantation in Pediatric Patients.

The use of hematopoietic stem cell transplantation (HSCT) is increasing for a variety of diseases. Ototoxicity from this procedure has not been extensively studied. A retrospective chart review examined 275 patients from this institution who underwent HSCT between January 1, 2007, and April 30, 2017.

Gene expression analysis to detect disseminated tumor cells in the bone marrow of triple-negative breast cancer patients predicts metastatic relapse.

Purpose: Disseminated tumor cells (DTCs) in the BM of breast cancer patients predict early disease relapse, but the molecular heterogeneity of these cells is less well characterized. Expression of a 46-gene panel was used to detect DTCs and classify patient BM samples to determine whether a composite set of biomarkers could better predict metastatic relapse.

Methods: Using a high-throughput qRT-PCR assay platform, BM specimens collected from 70 breast cancer patients prior to neoadjuvant therapy were analyzed for the expression of 46 gene transcripts.

Palbociclib and cetuximab in platinum-resistant and in cetuximab-resistant human papillomavirus-unrelated head and neck cancer: a multicentre, multigroup, phase 2 trial.

Background: Most head and neck squamous-cell carcinomas (HNSCCs) are driven by p16 inactivation and cyclin D1 overexpression that results in hyperactivation of cyclin-dependent kinase 4 and 6 (CDK4/6), rather than by the human papillomavirus (HPV). Deregulated cyclin D1 expression also causes resistance to EGFR inhibitors. We previously reported that palbociclib (a selective CDK4/6 inhibitor) given with cetuximab (an EGFR inhibitor) was safe.

Threat sensitivity is associated with the healthcare source used most often: doctor's office, emergency room, or none at all.

A significant proportion of American adults do not have a regular source of healthcare and the reasons for this shortfall are not fully understood. The objective of this study was to examine the relationship between individual differences in threat sensitivity and healthcare utilization in a survey of 483 African American men. Demographics, psychological characteristics, and health behaviors were assessed.

Phase II trial of levocetirizine with capecitabine and bevacizumab to overcome the resistance of antiangiogenic therapies in refractory metastatic colorectal cancer.

Background: Despite the clinical success of vascular endothelial growth factor (VEGF) blockade in metastatic colorectal cancers (mCRC), resistance to anti-angiogenic drugs invariably develops. IL-8 and other cytokines have been implicated in development of resistance to anti-angiogenic therapy. Levocetirizine is a second generation H1 antihistamine with anti-inflammatory and IL-8 suppression properties.

Giving Voice to Black Men: Guidance for Increasing the Likelihood of Having a Usual Source of Care.

Black men suffer inequalities in health and health-care outcomes relative to other racial/ethnic groups, requiring well-informed efforts for health promotion. Fewer Black men have a usual source of health care, which may be a contributor to these disparities. Increasing access to and the likelihood of a usual source of care among Black men are important to address health and health-care disparities.

Impact on Health-Related Quality of Life of Induction Chemotherapy Compared With Concurrent Cisplatin and Radiation Therapy in Patients With Head and Neck Cancer.

Aims: Organ preservation, an important goal in the treatment of head and neck squamous cell carcinoma (HNSCC), may include induction chemotherapy and cisplatin with radiation therapy (CRT). To our knowledge, no reports have directly compared the impact of induction chemotherapy with that of CRT on health-related quality of life (HRQOL).

Materials And Methods: In a phase II trial, we assessed the HRQOL of patients treated with induction chemotherapy followed by CRT.

Bone marrow dendritic cells regulate hematopoietic stem/progenitor cell trafficking.

A resident population of dendritic cells (DCs) has been identified in murine bone marrow, but its contribution to the regulation of hematopoiesis and establishment of the stem cell niche is largely unknown. Here, we show that murine bone marrow DCs are perivascular and have a type 2 conventional DC (cDC2) immunophenotype. RNA expression analysis of sorted bone marrow DCs shows that expression of many chemokines and chemokine receptors is distinct from that observed in splenic cDC2s, suggesting that bone marrow DCs may represent a unique DC population.

Geriatric Assessment in Older Adults with Multiple Myeloma.

Background/objectives: The incidence of myeloma in older adults is increasing, yet little is known about geriatric impairments in these patients. We aimed to examine the prevalence of geriatric impairments in older adults with myeloma and the association between geriatric assessment and autologous stem cell transplant eligibility.

Design: Prospective cohort study.

Effects of a Pasty Bone Cement Containing Brain-Derived Neurotrophic Factor-Functionalized Mesoporous Bioactive Glass Particles on Metaphyseal Healing in a New Murine Osteoporotic Fracture Model.

The development of new and better implant materials adapted to osteoporotic bone is still urgently required. Therefore, osteoporotic muscarinic acetylcholine receptor M3 (M3 mAChR) knockout (KO) and corresponding wild type (WT) mice underwent osteotomy in the distal femoral metaphysis. Fracture gaps were filled with a pasty α-tricalcium phosphate (α-TCP)-based hydroxyapatite (HA)-forming bone cement containing mesoporous bioactive CaP-SiO₂ glass particles (cement/MBG composite) with or without Brain-Derived Neurotrophic Factor (BDNF) and healing analyzed after 35 days.

Asymmetric sensorineural hearing loss is a risk factor for late-onset hearing loss in pediatric cancer survivors following cisplatin treatment.

Background: Ototoxicity is a significant complication of cisplatin treatment. Hearing loss can be symmetric or asymmetric, and may decline after therapy. This study examined the risks of asymmetric and late-onset hearing loss (LOHL) in cisplatin-treated pediatric patients with cancer.
