Disrupted uromodulin trafficking is rescued by targeting TMED cargo receptors.

The trafficking dynamics of uromodulin (UMOD), the most abundant protein in human urine, play a critical role in the pathogenesis of kidney disease. Monoallelic mutations in the UMOD gene cause autosomal dominant tubulointerstitial kidney disease (ADTKD-UMOD), an incurable genetic disorder that leads to kidney failure. The disease is caused by the intracellular entrapment of mutant UMOD in kidney epithelial cells, but the precise mechanisms mediating disrupted UMOD trafficking remain elusive.

Design of a pragmatic trial integrating human papillomavirus (HPV) self-sampling into primary care to reduce cervical cancer screening disparities in Somali American individuals: The Isbaar project.

Background: Somali American individuals have lower cervical cancer screening rates than the U.S. general population.

Doxorubicin, Paclitaxel, and Cisplatin (ATP) for Relapsed/Refractory Germ Cell Tumors.

Patients with relapsed/refractory germ cell tumors (GCT) have limited treatment options and poor survival outcomes. We describe our institutional experience with doxorubicin, paclitaxel, and cisplatin (ATP) as an outpatient regimen for 35 patients with relapsed/refractory GCT between 2017 and 2022. Twenty-four patients received nonpalliative intent ATP, with a median of 2 lines of prior therapy, 23 (96%) having received at least 1 cisplatin-based regimen and 1 (4%) with a prior stem cell transplant.

Artificial intelligence for diagnosing exudative age-related macular degeneration.

Background: Age-related macular degeneration (AMD) is a retinal disorder characterized by central retinal (macular) damage. Approximately 10% to 20% of non-exudative AMD cases progress to the exudative form, which may result in rapid deterioration of central vision. Individuals with exudative AMD (eAMD) need prompt consultation with retinal specialists to minimize the risk and extent of vision loss.

Real-time genomic characterization of pediatric acute leukemia using adaptive sampling.

Effective treatment of pediatric acute leukemia is dependent on accurate genomic classification, typically derived from a combination of multiple time-consuming and costly techniques such as flow cytometry, fluorescence hybridization (FISH), karyotype analysis, targeted PCR, and microarrays (Arber et al., 2016; Iacobucci & Mullighan, 2017; Narayanan & Weinberg, 2020). We investigated the feasibility of a comprehensive single-assay classification approach using long-read sequencing, with real-time genome target enrichment, to classify chromosomal abnormalities and structural variants characteristic of acute leukemia.

A PD-1-targeted, receptor-masked IL-2 immunocytokine that engages IL-2Rα strengthens T cell-mediated anti-tumor therapies.

The clinical use of interleukin-2 (IL-2) for cancer immunotherapy is limited by severe toxicity. Emerging IL-2 therapies with reduced IL-2 receptor alpha (IL-2Rα) binding aim to mitigate toxicity and regulatory T cell (Treg) expansion but have had limited clinical success. Here, we show that IL-2Rα engagement is critical for the anti-tumor activity of systemic IL-2 therapy.

Selective optogenetic inhibition of Gα or Gα signaling by minimal RGS domains disrupts circuit functionality and circuit formation.

Optogenetic techniques provide genetically targeted, spatially and temporally precise approaches to correlate cellular activities and physiological outcomes. In the nervous system, G protein-coupled receptors (GPCRs) have essential neuromodulatory functions through binding extracellular ligands to induce intracellular signaling cascades. In this work, we develop and validate an optogenetic tool that disrupts Gα signaling through membrane recruitment of a minimal regulator of G protein signaling (RGS) domain.

LTβR Agonism Promotes Antitumor Immune Responses via Modulation of the Tumor Microenvironment.

The presence of high endothelial venules (HEV) and tertiary lymphoid structures (TLS) in solid tumors is correlated with favorable prognosis and better responses to immune checkpoint blockade in many cancer types. Elucidation of the molecular mechanisms underlying intratumoral HEV and TLS formation and their contribution to antitumor responses may facilitate the development of improved treatment strategies. Lymphotoxin β receptor (LTβR) signaling is a critical regulator of lymph node organogenesis and can cooperate with antiangiogenic and immune checkpoint blockade treatment to augment tumor-associated HEV formation.

Vaccine effectiveness against anal HPV among men who have sex with men aged 18-45 years attending sexual health clinics in three United States cities, 2018-2023.

Background: We assessed human papillomavirus (HPV) vaccine effectiveness (VE) against anal HPV among men who have sex with men (MSM) in 2018-2023.

Methods: Residual anal specimens from MSM without HIV ages 18-45 years were tested for HPV. We calculated adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) for associations between vaccination (≥1 dose) and quadrivalent vaccine (4vHPV)-type prevalence adjusting for city, race/ethnicity, and non-vaccine-type HPV prevalence, stratified by age group (18-26, 27-45).

Risk factors for prolonged infection and secondary infection in pediatric severe sepsis.

Purpose: Sepsis causes significant worldwide morbidity and mortality. Inability to clear an infection and secondary infections are known complications in severe sepsis and likely result in worsened outcomes. We sought to characterize risk factors of these complications.

A Tetravalent Bispecific Antibody Selectively Inhibits Diverse FGFR3 Oncogenic Variants.

The receptor tyrosine kinase FGFR3 is frequently mutated in bladder cancer and is a validated therapeutic target. Although pan-FGFR tyrosine kinase inhibitors (TKI) have shown clinical efficacy, toxicity and acquired resistance limit the benefit of these agents. While antibody-based therapeutics can offer superior selectivity than TKIs, conventional ligand-blocking antibodies are usually ineffective inhibitors of constitutively active receptor tyrosine kinases.

Evidence-Based Practices for Interviewing Graduate Medical Education Applicants: A Systematic Review.

Although the selection interview is a standard admission practice for graduate medical education (GME) programs in the United States, there is a dearth of recent reviews on optimizing the trainee interview process, which has low reliability, high cost, and major risk of bias. To investigate the evidence base for different selection interview practices in GME. We searched 4 literature databases from inception through September 2022.

Gene Electrotransfer via Conductivity-Clamped Electric Field Focusing Pivots Sensori-Motor DNA Therapeutics: "A Spoonful of Sugar Helps the Medicine Go Down".

Viral vectors and lipofection-based gene therapies have dispersion-dependent transduction/transfection profiles that thwart precise targeting. The study describes the development of focused close-field gene electrotransfer (GET) technology, refining spatial control of gene expression. Integration of fluidics for precise delivery of "naked" plasmid deoxyribonucleic acid (DNA) in sucrose carrier within the focused electric field enables negative biasing of near-field conductivity ("conductivity-clamping"-CC), increasing the efficiency of plasma membrane molecular translocation.

Adherence and Correlates of Cervical Cancer Screening Among East African Immigrant Women in Washington State.

Introduction: Cervical cancer screening (CCS) among East African immigrants (EAI) in the USA is under explored. This study aimed to investigate adherence to CCS and its correlates among EAI.

Methods: We identified 1664 EAI women (25-65 years) with ≥ 1 primary care clinic visit(s) between 2017 and 2018, using University of Washington (UW) Medicine electronic health record data.

Methylation markers for anal cancer screening: A repeated cross-sectional analysis of people living with HIV, 2015-2016.

People living with HIV (PLWH) are at highest risk of anal cancer and will benefit from optimized screening for early disease detection. We compared host DNA methylation markers in high-grade squamous intraepithelial lesions (HSIL) versus samples negative for intraepithelial lesions (NILM) or low-grade intraepithelial lesions (LSIL) in PLWH. We recruited PLWH identifying as male aged ≥18 years undergoing high-resolution anoscopy (HRA) in Seattle, Washington, 2015-2016.
