Regulatory B-Cells Are Associated Negatively With Regulatory T-Cells and Positively With Cytokines in Peripheral Blood of Pregnant Women.

Problem: Regulatory B-cells (Bregs, CD19CD24CD38) are a specialized B-cell subset that suppresses immune responses and potentially contribute to the maintenance of an immune-privileged environment for fetal development during pregnancy. However, little is known about the surrounding immunological environment of Bregs in gestational physiology. The relationship of regulatory T-cells (Tregs, CD4CD25CD127FoxP3) to Bregs in coordinating immunoregulation during pregnancy is unknown.

Performance-Based Outcome Measures After Hip or Knee Arthroplasty: A Systematic Review and Content Analysis Using the International Classification of Functioning, Disability and Health (ICF).

Rational: One of the important considerations to select the appropriate outcome measures is determining if the tool is relevant to patients. Despite the availability of various performance-based tests to objectively assess function, it is unknown which performance-based tests best capture important aspects of function after hip or knee arthroplasty.

Aims And Objectives: Our systematic review aimed to identify the existing performance-based tests used in hip or knee arthroplasty and link the activity component of each test to the modified International Classification of Functioning, Disability and Health (ICF) core set for osteoarthritis (OA).

A phase 2 basket study of talabostat, a small-molecule inhibitor of dipeptidyl peptidases, administered in combination with pembrolizumab in patients with advanced solid cancers.

Background: Talabostat, an oral small molecule inhibitor of dipeptidyl peptidases (DPP4 and DPP8/9), has shown synergistic activity with immune checkpoint inhibitors in preclinical studies. This open label, phase 2 basket trial assessed the antitumor activity of combining talabostat and pembrolizumab (anti-programmed death-1 antibody) in advanced solid tumor patients.

Methods: The primary objective was assessment of dose-limiting toxicity (DLT) rates in the first six patients (lead-in stage) and response rate (efficacy stage; included cohort A [checkpoint inhibitor (ICI) naive] and cohort B [ICI pretreated]) for the study treatment using the Response Evaluation Criteria in Solid Tumors (RECIST) v1.

Nutraceuticals and Headache 2024: Riboflavin, Coenzyme Q10, Feverfew, Magnesium, Melatonin, and Butterbur.

Nutraceuticals are not regulated by the US Food and Drug Administration, so a careful literature review is essential to make clinical decisions. Riboflavin or vitamin B2 can be recommended for migraine prevention in adults, but pediatric use is not proven. Adverse events are minimal.

Proximal remote sensing: an essential tool for bridging the gap between high-resolution ecosystem monitoring and global ecology.

A new proliferation of optical instruments that can be attached to towers over or within ecosystems, or 'proximal' remote sensing, enables a comprehensive characterization of terrestrial ecosystem structure, function, and fluxes of energy, water, and carbon. Proximal remote sensing can bridge the gap between individual plants, site-level eddy-covariance fluxes, and airborne and spaceborne remote sensing by providing continuous data at a high-spatiotemporal resolution. Here, we review recent advances in proximal remote sensing for improving our mechanistic understanding of plant and ecosystem processes, model development, and validation of current and upcoming satellite missions.

The impact of imprecise case definitions in electronic health record research: a melanoma case-study from the Million Veteran Program.

Cases for a disease can be defined broadly using diagnostic codes, or narrowly using gold-standard confirmation that often is not available in large administrative datasets. These different definitions can have significant impacts on the results and conclusions of studies. We conducted this study to assess how using melanoma phecodes versus histologic confirmation for invasive or in situ melanoma impacts the results of a genome-wide association study (GWAS) using the Million Veteran Program.

The family medicine accelerated track at Texas Tech University Health Sciences Center: results from a 10-year program to bend the primary care curve.

Background: Texas is one of the states with the lowest access to usual sources of primary care; most critically, family medicine (FM) has been projected to have the greatest physician shortage increase between 2018 and 2032. Texas Tech University Health Sciences Center (TTUHSC) School of Medicine developed the Family Medicine Accelerated Track (FMAT), a 3-year curriculum that culminates in the MD degree and links medical students to FM residency programs at TTUHSC campuses in Lubbock, Amarillo or the Permian Basin. This article reflects on 10 years of experience with the program, and particularly its impact on the primary care physician workforce in Texas.

Absolute quantification of amine metabolites in human cerebrospinal fluid via MS1-centric isotopic N,N-dimethyl leucine (iDiLeu) labeling.

Quantitative measurement of metabolites is essential to understand biological and disease processes. Absolute quantification by spiking heavy isotope-labeled internal standards and analyzing on mass spectrometry (MS) platform is a key method to determine the concentration of metabolites in biological samples. However, MS-based absolute quantification is often challenged by the commercial availability and high costs of isotope-labeled internal standards.

Clinical use of measurable residual disease in adult ALL: recommendations from a panel of U.S. experts.

Measurable residual disease (MRD) is a powerful predictor of clinical outcomes in acute lymphoblastic leukemia (ALL). In addition to its clear prognostic importance, MRD information is increasingly used in clinical decision algorithms to guide therapeutic interventions. While it is well-established that achievement of MRD-negative remission is an important endpoint of ALL therapy, the prognostic and therapeutic implications of MRD in an individual patient are influenced by both disease-related factors (e.

Different PD-L1 Assays Reveal Distinct Immunobiology and Clinical Outcomes in Urothelial Cancer.

Testing for PD-L1 expression by immunohistochemistry (IHC) is used to predict immune checkpoint blockade (ICB) benefit but has performed inconsistently in urothelial cancer (UC) clinical trials. Different approaches are used for PD-L1 IHC. We analyzed paired PD-L1 IHC data on UC samples using the SP142 and 22C3 assays from the phase 3 IMvigor130 trial and found discordant findings summarized by four phenotypes: PD-L1 positive by both assays (PD-L1 double positive; PD-L1DP), PD-L1 positive by the SP142 assay only (SP142 single positive; SP142SP), PD-L1 positive by the 22C3 assay only (22C3 single positive; 22C3SP), and PD-L1 negative by both assays double negative (PD-L1 double negative; PD-L1DN).

Optimized genetic tools for neuroanatomical and functional mapping of the Aedes aegypti olfactory system.

The mosquito Aedes aegypti is an emerging model insect for invertebrate neurobiology. We detail the application of a dual transgenesis marker system that reports the nature of transgene integration with circular donor template for CRISPR-Cas9-mediated homology-directed repair at target mosquito chemoreceptor genes. Employing this approach, we demonstrate the establishment of cell-type-specific T2A-QF2 driver lines for the A.

TP53 Mutant Variant Allele Frequency and Cytogenetics Determine Prognostic Groups in MDS/AML for Transplantation.

Results following hematopoietic stem cell transplantation (HSCT) for TP53-mutated myeloid malignancies are disappointing. Several HSCT centers decline to perform HSCT for patients with TP53 mutation because of poor outcomes. In this study, we analyzed 240 patients with TP53-mutated myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) that underwent HSCT.

Accumulation of CD38 in Hybrid Epithelial/Mesenchymal Cells Promotes Immune Remodeling and Metastasis in Breast Cancer.

Triple-negative breast cancer (TNBC) is a highly metastatic subtype of breast cancer. The epithelial-to-mesenchymal transition is a nonbinary process in the metastatic cascade that generates tumor cells with both epithelial and mesenchymal traits known as hybrid EM cells. Recent studies have elucidated the enhanced metastatic potential of cancers featuring the hybrid EM phenotype, highlighting the need to uncover molecular drivers and targetable vulnerabilities of the hybrid EM state.
