Clinical Characteristics, Cytogenetic Risks, and Prognoses of Young Multiple Myeloma Patients in the Era of Novel Therapies.

In recent years, there have been significant advances in the understanding and treatment of multiple myeloma (MM). Despite this progress, there is still limited information on the disease in patients aged 50 or younger, including the impact of young age on disease characteristics, treatment, and outcome. In this retrospective study, we analyzed 68 newly diagnosed MM patients aged ≤ 50 years (y) who had undergone at least one peripheral blood stem cell transplantation (PBSCT).

Digest: Habitat associations shape a hybrid zone in killifish.

Hybrid zones provide valuable opportunities to interrogate the processes that drive speciation. In a new study, Hardy et al. (2024) demonstrate that the dominant vegetation type in patchy cordgrass salt marshes and mangrove swamps drives a mosaic hybrid zone between two species of killifish.

Rearrangements of viral and human genomes at human papillomavirus integration events and their allele-specific impacts on cancer genome regulation.

Human papillomavirus (HPV) integration has been implicated in transforming HPV infection into cancer. To resolve genome dysregulation associated with HPV integration, we performed Oxford Nanopore long-read sequencing on 72 cervical cancer genomes from an Ugandan dataset that was previously characterized using short-read sequencing. We found recurrent structural rearrangement patterns at HPV integration events, which we categorized as: del(etion)-like, dup(lication)-like, translocation, multibreakpoint, or repeat region integrations.

Temperature affects conspecific and heterospecific mating rates in .

Behavioral mating choices and mating success are important factors in the development of reproductive isolation during speciation. Environmental conditions, especially temperature, can affect these key traits. Environmental conditions can vary across, and frequently delimit species' geographic ranges.

Immunohistochemistry in the Differential Diagnosis of Triple Negative Breast Carcinoma and High-grade Serous Carcinoma: Old and New Markers.

Distinction of metastasis to the breast from a breast primary, particularly high-grade triple-negative breast cancer (TNBC), can be challenging due to nonspecific morphology and immunohistochemical (IHC) profiles. Among metastases to the breast, high-grade serous carcinoma (HGSC) of müllerian origin is most likely to be misdiagnosed as TNBC. We assessed breast and müllerian markers on TNBC and HGSC, including keratin 7, keratin 20, GATA3, GCDFP15, mammaglobin, p53, PAX8 (MRQ50 and BC12 clones), TRPS1, SOX10, and WT1.

Optimizing individualized therapy decision-making in multiple myeloma (MM): integration and impact of the Revised Myeloma Comorbidity Index in the MM-tumor board.

Multiple Myeloma (MM) is a hematological disease predominantly affecting elderly patients. The complexity of current treatment necessitates individualized approaches. Therein, functional assessment (FA) tools, such as the Revised Comorbidity Index (R-MCI) at our University- and Comprehensive Cancer Center Freiburg, play a crucial role.

Deciphering the divergent transcriptomic landscapes of cervical cancer cells grown in 3D and 2D cell culture systems.

Cervical cancer remains a significant health challenge for women worldwide, with a disproportionate impact on developing regions like sub-Saharan Africa. Taking advantage of recent advancements in developing suitable preclinical models to study cell proliferation, differentiation, and gene expression, we used RNA sequencing to compare the transcriptomic profiles of SiHa cervical cancer cells grown in 3D versus 2D culture systems. Pathway analysis of 3D cultures revealed upregulation of immune activation, angiogenesis, and tissue remodeling pathways.

Turkey vultures tune their airspeed to changing air density.

Animals must tune their physical performance to changing environmental conditions, and the breadth of environmental tolerance may contribute to delineating the geographic range of a species. A common environmental challenge that flying animals face is the reduction of air density at high elevation and the reduction in the effectiveness of lift production that accompanies it. As a species, turkey vultures (Cathartes aura) inhabit a >3000 m elevation range, and fly considerably higher, necessitating that they accommodate for a 27% change in air density (0.

Physical activity and exercise motivation of multiple myeloma patients: a prospective cross-sectional study.

Background: Multiple myeloma (MM) is the second most common hematological malignancy with its prevalence increasing. Patients with symptomatic MM can show numerous comorbidities, affecting their quality of life (QoL). Physical activity (PA) may improve QoL but is not a standardized intervention of comprehensive cancer centers (CCCs).

Landscape of potential germline pathogenic variants in select cancer susceptibility genes in patients with adult-type ovarian granulosa cell tumors.

Objective: The objective of this study was to assess the frequency of potential germline pathogenic variants that may contribute to risk of development of adult granulosa cell tumors (AGCT) given the paucity of germline testing guidelines for these patients.

Methods: This was a retrospective cross-sectional study analyzing comprehensive genomic profiling (CGP) results of AGCT with the FOXL2 p.C134W mutation submitted to Foundation Medicine between 2012 and 2022.

Humidity and temperature preference in two Neotropical species of sand flies.

Background: Arthropods vector a multitude of human disease-causing organisms, and their geographic ranges are shifting rapidly in response to changing climatic conditions. This is, in turn, altering the landscape of disease risk for human populations that are brought into novel contact with the vectors and the diseases they carry. Sand flies in the genera Lutzomyia and Pintomyia are vectors of serious disease-causing agents such as Leishmania (the etiological agent of leishmaniasis) and may be expanding their range in the face of climate change.

Phenotypic characterization of cryptic species in the fungal pathogen .

Histoplasmosis is an endemic mycosis that often presents as a respiratory infection in immunocompromised patients. Hundreds of thousands of new infections are reported annually around the world. The etiological agent of the disease, is a dimorphic fungus commonly found in the soil where it grows as mycelia.

Clinicopathologic Characteristics of a Single-institution Cohort of Ovarian Adult Granulosa Cell Tumors, With Biomarker and Therapeutic Implications Utilizing the Detection of Androgen, Estrogen, and Progesterone Hormone Receptor Expression by Immunohistochemistry.

Adult granulosa cell tumors (AGCTs) are rare ovarian tumors with generally good prognosis after surgical resection; however, they do have recurrence potential. Therapeutic and management options for recurrences are currently limited, and the need for expanded adjuvant therapies is increasingly recognized. Anti-hormonal therapy is being explored as an option, which relies on the detection and assessment of hormone receptor expression (androgen, estrogen, and progesterone receptors) as a biomarker and therapeutic target.

Carboplatin, paclitaxel, and pembrolizumab followed by pembrolizumab maintenance for primary treatment of incompletely resected epithelial ovarian cancer.

Objective: Incompletely resected epithelial ovarian cancer represents a poor prognostic subset of patients. Novel treatment strategies are needed to improve outcomes for this population. We evaluated a treatment strategy combining platinum-based chemotherapy with pembrolizumab followed by pembrolizumab maintenance therapy in the first-line treatment after incomplete resection of epithelial ovarian cancer patients.

The spread of Aedes albopictus (Diptera: Culicidae) in the islands of São Tomé and Príncipe.

The mosquito Aedes albopictus (Diptera: Culicidae) is a vector species of the causal agents of Dengue, yellow fever, and Zika among other diseases pathogens. The species originated in Southeast Asia and has spread widely and rapidly in the last century. The species has been reported in localities from the Gulf of Guinea since the early 2000s, but systematic sampling has been scant.

Morphological evolution of bird wings follows a mechanical sensitivity gradient determined by the aerodynamics of flapping flight.

The physical principles that govern the function of biological structures also mediate their evolution, but the evolutionary drivers of morphological traits within complex structures can be difficult to predict. Here, we use morphological traits measured from 1096 3-dimensional bird wing scans from 178 species to test the interaction of two frameworks for relating morphology to evolution. We examine whether the evolutionary rate (σ) and mode is dominated by the modular organization of the wing into handwing and armwing regions, and/or the relationship between trait morphology and functional output (i.

PhyloMatcher: a tool for resolving conflicts in taxonomic nomenclature.

Summary: Large-scale comparative studies rely on the application of both phylogenetic trees and phenotypic data, both of which come from a variety of sources, but due to the changing nature of phylogenetic classification over time, many taxon names in comparative datasets do not match the nomenclature in phylogenetic trees. Manual curation of taxonomic synonyms in large comparative datasets can be daunting. To address this issue, we introduce PhyloMatcher, a tool which allows for programmatic querying of the National Center for Biotechnology Information Taxonomy and Global Biodiversity Information Facility databases to find associated synonyms with given target species names.

Isotopic niches do not follow the expectations of niche conservatism in the bird genus Cinclodes.

Phenotypic traits are expected to be more similar among closely related species than among species that diverged long ago (all else being equal). This pattern, known as phylogenetic niche conservatism, also applies to traits that are important to determine the niche of species. To test this hypothesis on ecological niches, we analysed isotopic data from 254 museum study skins from 12 of the 16 species of the bird genus Cinclodes and measured stable isotope ratios for four different elements: carbon, nitrogen, hydrogen and oxygen.

Digest: A new tool will illuminate patterns of morphological integration.

Morphological integration is the result of natural selection influencing the evolution of multiple morphological traits simultaneously. Understanding how and why morphological traits covary is fundamental to uncovering the processes that drive phenotypic diversity. In a new study, Conaway and Adams (2022) review the utility of several methods for quantifying morphological integration and provide a new metric that will facilitate broad, novel comparisons of morphological integration among taxa and between different morphological features.

A case series of triplet anti-hormonal therapy in androgen receptor-positive recurrent adult ovarian granulosa cell tumor.

Therapeutic options for recurrent adult granulosa cell tumors (AGCT) are limited. After examining the hormonal pathways involved in -mutated granulosa cell tumor development, a novel treatment regimen was utilized for recurrent AGCT: a combination of an androgen receptor antagonist, a gonadotropin-releasing hormone receptor agonist, and an aromatase inhibitor for hormonal blockade. In this case series, seven patients at our institution were treated with bicalutamide 50 mg orally once daily, Leuprolide acetate 7.
