Has PD-1 blockade changed the standard of care for cHL?

The treatment paradigm for classic Hodgkin lymphoma (CHL) continues to evolve, particularly in light of the incorporation of programmed cell death protein 1 (PD-1) inhibitors into a variety of therapeutic settings. PD-1 inhibitors have demonstrated high efficacy and a favorable toxicity profile when added to a doxorubicin, vinblastine, dacarbazine chemotherapy backbone in patients with untreated CHL. PD-1 inhibitors are also effective treatment options in the relapsed/refractory setting.

Managing common toxicities associated with checkpoint inhibitor and chemotherapy combinations for untreated classic Hodgkin lymphoma.

Combination checkpoint inhibitor (CPI) and chemotherapy is an effective and safe treatment strategy for patients with untreated classic Hodgkin lymphoma. Recent studies of programmed cell death protein 1 inhibitors combined with doxorubicin, vinblastine and dacarbazine have demonstrated high overall and complete response rates. This combination has a unique toxicity profile that should be managed appropriately so as not to compromise treatment efficacy.

Depression in patients with hematologic malignancies: The current landscape and future directions.

Patients with hematologic malignancies experience high rates of depression. These patients are vulnerable to depression throughout the disease trajectory, from diagnosis to survivorship, and at the end of life. In addition to the distressing nature of depression, it has substantial downstream effects including poor quality of life, increased risk of treatment complications, and worse survival.

Mortality among patients with diffuse large B-cell lymphoma and mental disorders: a population-based study.

Background: Mental disorders have been reported in patients with diffuse large B-cell lymphoma (DLBCL), but studies examining their association with mortality are lacking.

Methods: We conducted a population-based study using linked administrative health-care databases from Ontario, Canada. All patients with DLBCL 18 years of age or older treated with rituximab-based therapy between January 1, 2005, and December 31, 2017, were identified and followed until March 1, 2020.

Mental health disorders and survival among older patients with diffuse large B-cell lymphoma in the USA: a population-based study.

Background: Mental health disorders can potentially decrease quality of life and survival in patients with cancer. Little is known about the survival implications of mental health disorders in patients with diffuse large B-cell lymphoma (DLBCL). We aimed to evaluate the effect of pre-existing depression, anxiety, or both on survival in a US cohort of older patients with DLBCL.

Precancer and cancer-associated depression and anxiety among older adults with blood cancers in the United States.

For patients with blood cancers, comorbid mental health disorders at diagnosis likely affect the entire disease trajectory, as they can interfere with disease information processing, lead to poor coping, and even cause delays in care. We aimed to characterize the prevalence of depression and anxiety in patients with blood cancers. Using the Surveillance, Epidemiology, and End Results-Medicare database, we identified patients ≥67 years old diagnosed with lymphoma, myeloma, leukemia, or myelodysplastic syndromes between 2000 and 2015.

Impact of cryopreservation and transit times of allogeneic grafts on hematopoietic and immune reconstitution.

We sought to evaluate the impact of cryopreservation of unrelated donor (URD) peripheral blood stem cell (PBSC) grafts on engraftment, chimerism, and immune reconstitution in the context of the COVID-19 pandemic. We reviewed stem cell product characteristics and clinical outcomes in 101 patients receiving cryopreserved PBSCs from URDs between January 1, 2019 and 31 December, 2020, compared with 203 patients receiving fresh URD PBSCs. We observed no differences in 6-month overall survival, progression-free survival, or nonrelapse mortality.

Goal of a "Good Death" in End-of-Life Care for Patients with Hematologic Malignancies-Are We Close?

Purpose Of Review: The medical field has a critical role not only in prolonging life but also in helping patients achieve a good death. Early studies assessing end-of-life quality indicators to capture if a good death occurred demonstrated low rates of hospice use and high rates of intensive healthcare utilization near death among patients with hematologic malignancies, raising concerns about the quality of death. In this review, we examine trends in end-of-life care for patients with hematologic malignancies to determine if we are close to the goal of a good death.

Medical history of chemotherapy or immunosuppressive drug treatment and risk of amyotrophic lateral sclerosis (ALS).

A recent population-based analysis demonstrated lower risk of the lethal degenerative neuromuscular disease, amyotrophic lateral sclerosis (ALS) associated with history of the use of 'antineoplastic agents' and 'immunosuppressants'. To see if this finding was generalizable to other ALS cohorts, we examined associations between use of these agents and ALS risk in an independent case-control study of n = 414 ALS patients and n = 361 controls in an Eastern US population. Controls were sampled from the general population and among non-neurodegenerative disease patients.

How do Medical Societies Select Science for Conference Presentation? How Should They?

Introduction: Nothing has been published to describe the practices of medical societies in choosing abstracts for presentations at their annual meetings. We surveyed medical societies to determine their practices, and also present a theoretical analysis of the topic.

Methods: We contacted a convenience sample of large U.

MannDB - a microbial database of automated protein sequence analyses and evidence integration for protein characterization.

Background: MannDB was created to meet a need for rapid, comprehensive automated protein sequence analyses to support selection of proteins suitable as targets for driving the development of reagents for pathogen or protein toxin detection. Because a large number of open-source tools were needed, it was necessary to produce a software system to scale the computations for whole-proteome analysis. Thus, we built a fully automated system for executing software tools and for storage, integration, and display of automated protein sequence analysis and annotation data.

System to assess genome sequencing needs for viral protein diagnostics and therapeutics.

Computational analyses of genome sequences may elucidate protein signatures unique to a target pathogen. We constructed a Protein Signature Pipeline to guide the selection of short peptide sequences to serve as targets for detection and therapeutics. In silico identification of good target peptides that are conserved among strains and unique compared to other species generates a list of peptides.

Limitations of TaqMan PCR for detecting divergent viral pathogens illustrated by hepatitis A, B, C, and E viruses and human immunodeficiency virus.

Recent events illustrate the imperative to rapidly and accurately detect and identify pathogens during disease outbreaks, whether they are natural or engineered. Particularly for our primary goal of detecting bioterrorist releases, detection techniques must be both species-wide (capable of detecting all known strains of a given species) and species specific. Due to classification restrictions on the publication of data for species that may pose a bioterror threat, we illustrate the challenges of finding such assays using five nonthreat organisms that are nevertheless of public health concern: human immunodeficiency virus (HIV) and four species of hepatitis viruses.

High-density microarray of small-subunit ribosomal DNA probes.

Ribosomal DNA sequence analysis, originally conceived as a way to provide a universal phylogeny for life forms, has proven useful in many areas of biological research. Some of the most promising applications of this approach are presently limited by the rate at which sequences can be analyzed. As a step toward overcoming this limitation, we have investigated the use of photolithography chip technology to perform sequence analyses on amplified small-subunit rRNA genes.
