Autogene cevumeran with or without atezolizumab in advanced solid tumors: a phase 1 trial.

Effective targeting of somatic cancer mutations to enhance the efficacy of cancer immunotherapy requires an individualized approach. Autogene cevumeran is a uridine messenger RNA lipoplex-based individualized neoantigen-specific immunotherapy designed from tumor-specific somatic mutation data obtained from tumor tissue of each individual patient to stimulate T cell responses against up to 20 neoantigens. This ongoing phase 1 study evaluated autogene cevumeran as monotherapy (n = 30) and in combination with atezolizumab (n = 183) in pretreated patients with advanced solid tumors.

F-FLT PET and Blood-based Biomarkers for Identifying Gastrointestinal Graft versus Host Disease after Allogeneic Cell Transplantation.

Purpose To determine whether fluorine 18 (F) fluorothymidine (FLT) PET imaging alone or combined with Mount Sinai Acute GVHD International Consortium (MAGIC) biomarkers could help identify subclinical gastrointestinal graft versus host disease (GI-GVHD) by day 100 following hematopoietic stem cell transplantation (HSCT). Materials and Methods F-FLT PET imaging was analyzed in a prospective pilot study (ClinicalTrials.gov identifier no.

Dietary restriction impacts health and lifespan of genetically diverse mice.

Caloric restriction extends healthy lifespan in multiple species. Intermittent fasting, an alternative form of dietary restriction, is potentially more sustainable in humans, but its effectiveness remains largely unexplored. Identifying the most efficacious forms of dietary restriction is key for developing interventions to improve human health and longevity.

Steering research on mRNA splicing in cancer towards clinical translation.

Splicing factors are affected by recurrent somatic mutations and copy number variations in several types of haematologic and solid malignancies, which is often seen as prima facie evidence that splicing aberrations can drive cancer initiation and progression. However, numerous spliceosome components also 'moonlight' in DNA repair and other cellular processes, making their precise role in cancer difficult to pinpoint. Still, few would deny that dysregulated mRNA splicing is a pervasive feature of most cancers.

Fingerprinting Tertiary Structure in Complex RNAs Using Single-Molecule Correlated Chemical Probing.

Single-molecule correlated chemical probing (smCCP) is an experimentally concise strategy for characterizing higher-order structural interactions in RNA. smCCP data yield rich, but complex, information about base pairing, conformational ensembles, and tertiary interactions. To date, through-space communication specifically measuring RNA tertiary structure has been difficult to isolate from structural communication reflective of other interactions.

Are new pediatric trauma centers located close to the high-risk populations? A geolocation study.

Background: Higher rates of injury occur in children who live in low socioeconomic areas. Since 2010, the number of verified Level I and Level II pediatric trauma centers (PTCs) has doubled. The purpose of this study is to look at the location of new verified PTC in relation to children living in high-risk areas.

Intraoperative factors associated with unplanned return to the operating room after emergent hemorrhage control surgery.

Background: Unplanned return to the operating room (uROR) is associated with worse outcomes and increased mortality. Little is known regarding intraoperative factors associated with uROR after emergent surgery in trauma patients. The objective of this study was to identify intraoperative factors associated with uROR after emergent hemorrhage control procedures in bleeding trauma patients.

Factors affecting discrepancies in disease activity evaluation between patients and physicians in systemic lupus erythematosus-The importance of symptoms such as fatigue.

Objectives: There are often discrepancies in the evaluation of disease activity between patients and physicians in systemic lupus erythematosus (SLE). In this study, we examined the factors that affect those evaluations.

Methods: Physician visual analogue scale (Ph-VAS), patient VAS (Pt-VAS), Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2k), glucocorticoid (GC) usage and dose, age, Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index, and three patient-reported outcomes (SLE symptom checklist [SSC], short-form 36 questionnaire [SF-36], and LupusPRO) were obtained from a study performed in 2019 using 225 SLE outpatients of the Kyoto Lupus Cohort at Kyoto University Hospital.

Ophthalmic Immune-Related Adverse Events and Association with Survival: Results From a Real-World Database.

Purpose: Assessing immune-related ocular toxicities from immune checkpoint inhibitors (ICIs) is crucial, though rare. This study, utilizing real-world data, examines the occurrence of ophthalmic immune-related adverse events (irAEs) after ICI treatment and their impact on overall survival.

Design: A retrospective cohort study.

Methylated DNA Markers in Voided Urine for the Identification of Clinically Significant Prostate Cancer.

Introduction: Non-invasive assays are needed to better discriminate patients with prostate cancer (PCa) to avoid over-treatment of indolent disease. We analyzed 14 methylated DNA markers (MDMs) from urine samples of patients with biopsy-proven PCa relative to healthy controls and further studied discrimination of clinically significant PCa (csPCa) from healthy controls and Gleason 6 cancers.

Methods: To evaluate the panel, urine from 24 healthy male volunteers with no clinical suspicion for PCa and 24 men with biopsy-confirmed disease across all Gleason scores was collected.

Impact of Obstructive Sleep Apnea on Diabetic Retinopathy Progression and Systemic Complications.

Purpose: To evaluate the risk of diabetic retinopathy progression and systemic vascular events, including death, in patients with nonproliferative diabetic retinopathy (NPDR) with obstructive sleep apnea (OSA).

Design: Retrospective cohort study.

Methods: Electronic chart query using TriNetX, an electronic health records network comprising data from over 124 million patients.

Visualizing RNA structure ensembles by single-molecule correlated chemical probing.

RNA molecules fold to form complex internal structures. Many of these RNA structures populate ensembles with rheostat-like properties, with each state having a distinct function. Until recently, analysis of RNA structures, especially within cells, was limited to modeling either a single averaged structure or computationally-modeled ensembles.

Molecular Analysis of Persistent and Recurrent Barrett's Esophagus in the Setting of Endoscopic Therapy.

Introduction: Early neoplastic progression of Barrett's esophagus (BE) is often treated with endoscopic therapy. Although effective, some patients are refractory to therapy or recur after apparent eradication of the BE. The goal of this study was to determine whether genomic alterations within the treated BE may be associated with persistent or recurrent disease.

Scaffold-enabled high-resolution cryo-EM structure determination of RNA.

Cryo-EM structure determination of protein-free RNAs has remained difficult with most attempts yielding low to moderate resolution and lacking nucleotide-level detail. These difficulties are compounded for small RNAs as cryo-EM is inherently more difficult for lower molecular weight macromolecules. Here we present a strategy for fusing small RNAs to a group II intron that yields high resolution structures of the appended RNA, which we demonstrate with the 86-nucleotide thiamine pyrophosphate (TPP) riboswitch, and visualizing the riboswitch ligand binding pocket at 2.

TGF-β signalling limits effector function capacity of NK cell anti-tumour immunity in human bladder cancer.

Background: Natural killer (NK) cells are important innate immunity players and have unique abilities to recognize and eliminate cancer cells, particularly in settings of antibody-opsonization and antibody-dependant cellular cytotoxicity (ADCC). However, NK cell-based responses in bladder cancers to therapeutic antibodies are typically immunosuppressed, and these immunosuppressive mechanisms are largely unknown.

Methods: Single cell RNA sequencing (scRNA-seq) and high-dimensional flow cytometry were used to investigate the phenotype of tumour-infiltrating NK cells in patients with bladder cancer.

Deleting the mitochondrial respiration negative regulator MCJ enhances the efficacy of CD8 T cell adoptive therapies in pre-clinical studies.

Mitochondrial respiration is essential for the survival and function of T cells used in adoptive cellular therapies. However, strategies that specifically enhance mitochondrial respiration to promote T cell function remain limited. Here, we investigate methylation-controlled J protein (MCJ), an endogenous negative regulator of mitochondrial complex I expressed in CD8 cells, as a target for improving the efficacy of adoptive T cell therapies.
