The FBXO45-GEF-H1 axis controls germinal center formation and B-cell lymphomagenesis.

The role of ubiquitin-mediated degradation mechanisms in the pathogenesis of diffuse large B cell (DLBCL) and follicular lymphoma (FL) is not completely understood. We show that conditional deletion of the E3 ubiquitin ligase Fbxo45 in germinal center B-cells results in B-cell lymphomagenesis in homozygous (100%) and heterozygous (48%) mice. Mechanistically, FBXO45 targets the RHO guanine exchange factor ARHGEF2/GEF-H1 for ubiquitin-mediated degradation.

Household needs among wildfire survivors in the 2017 Northern California wildfires.

Wildfires are impacting communities globally, with California wildfires often breaking records of size and destructiveness. Knowing how communities are affected by these wildfires is vital to understanding recovery. We sought to identify impacted communities' post-wildfire needs and characterize how those needs change over time.

Multi-omic biomarker panel in pancreatic cyst fluid and serum predicts patients at a high risk of pancreatic cancer development.

Integration of multi-omic data for the purposes of biomarker discovery can provide novel and robust panels across multiple biological compartments. Appropriate analytical methods are key to ensuring accurate and meaningful outputs in the multi-omic setting. Here, we extensively profile the proteome and transcriptome of patient pancreatic cyst fluid (PCF) (n = 32) and serum (n = 68), before integrating matched omic and biofluid data, to identify biomarkers of pancreatic cancer risk.

Updates on pancreatic cancer treatment - invited special issue.

Despite an increased understanding of the underlying biology of the disease, pancreatic ductal adenocarcinoma (PDAC) remains a challenging condition with poor outcomes and a 5-year survival rate, even at an early stage, of less than 10%. This dismal prognosis is due in part to biological aggressiveness, the lack of early diagnosis, suboptimal surgical selection, and the need for effective neoadjuvant and adjuvant therapies. However, progress is being made with significant advancements in the diagnosis, staging, and treatment of PDAC, with a focus on precision therapy, improved surgical care, and supportive care, coupled with a deeper understanding of PDAC's biology.

Methods: A retrospective observational cohort study was conducted on all adult patients (> 18 years age) diagnosed with adrenal myelolipoma from January 1, 2014, to December 30, 2022.

Screening for undiagnosed pancreatic exocrine insufficiency (PEI) in a cohort of diabetic patients using faecal elastase testing and PEI scoring system.

Introduction: Type 1 and type 2 diabetes mellitus (DM) are often accompanied by mild forms of pancreatic exocrine insufficiency (PEI). The prevalence rates of PEI in diabetic patients are unclear and variable depending on the testing modality and the studies published. The clinical consequences of PEI in diabetics are also not well defined.

Global producer responsibility for plastic pollution.

Brand names can be used to hold plastic companies accountable for their items found polluting the environment. We used data from a 5-year (2018-2022) worldwide (84 countries) program to identify brands found on plastic items in the environment through 1576 audit events. We found that 50% of items were unbranded, calling for mandated producer reporting.

A RETROSPECTIVE EVALUATION OF MORBIDITY AND MORTALITY IN ASSOCIATION WITH INFESTATION BY THE MITE IN AN AVIARY-HOUSED POPULATION OF GOULDIAN FINCHES ().

The Rhynonyssid mesostigmatic mite, , is a well-documented endoparasitic hematophagous arthropod of the respiratory tracts of multiple avian species, particularly Estrildid finches and canaries. In this retrospective study, 175 medical and 278 pathology records for the Gouldian finch () population (N = 377) at the San Diego Zoo between 2013 and 2021 were analyzed to evaluate the effectiveness of ivermectin-based prophylaxis. A multivariable negative binomial regression model was constructed to evaluate the population effects of monthly treatments on morbidity or mortality associated with respiratory mites.

Health and equity implications of individual adaptation to air pollution in a changing climate.

Future climate change can cause more days with poor air quality. This could trigger more alerts telling people to stay inside to protect themselves, with potential consequences for health and health equity. Here, we study the change in US air quality alerts over this century due to fine particulate matter (PM), who they may affect, and how they may respond.

Surgery versus Endoscopy for the Management of Painful Chronic Pancreatitis: A Systematic Review and Meta-Analysis of Randomized Trials.

Background: Debate exists regarding the optimal treatment for painful chronic pancreatitis (CP). This meta-analysis aims to determine the outcomes of surgical intervention as compared to endoscopy in patients with painful CP.

Methods: A systematic review and meta-analysis including studies from PubMed, Embase, Web of Science, and Cochrane Databases (1995 onwards) was done by two independent reviewers using PRISMA guidelines.

First-in-human phase I/Ib study of NIZ985, a recombinant heterodimer of IL-15 and IL-15Rα, as a single agent and in combination with spartalizumab in patients with advanced and metastatic solid tumors.

Background: Preclinically, interleukin-15 (IL-15) monotherapy promotes antitumor immune responses, which are enhanced when IL-15 is used in combination with immune checkpoint inhibitors (ICIs). This first-in-human study investigated NIZ985, a recombinant heterodimer comprising physiologically active IL-15 and IL-15 receptor α, as monotherapy and in combination with spartalizumab, an anti-programmed cell death protein-1 (anti-PD-1) monoclonal antibody, in patients with advanced solid tumors.

Methods: This phase I/Ib study had two dose-escalation arms: single-agent NIZ985 administered subcutaneously thrice weekly (TIW, 2 weeks on/2 weeks off) or once weekly (QW, 3 weeks on/1 week off), and NIZ985 TIW or QW administered subcutaneously plus spartalizumab (400 mg intravenously every 4 weeks (Q4W)).

Obesity, Sarcopenia and Myosteatosis: Impact on Clinical Outcomes in the Operative Management of Crohn's Disease.

Background: Obesity, sarcopenia, and myosteatosis in inflammatory bowel disease may confer negative outcomes, but their prevalence and impact among patients with Crohn's disease (CD) have not been systematically studied. The aim of this study was to assess nutritional status and body composition among patients undergoing resectional surgery for CD and determine impact on operative outcomes.

Methods: Consecutive patients with CD undergoing resection from 2000 to 2018 were studied.

RORγt-Raftlin1 complex regulates the pathogenicity of Th17 cells and colonic inflammation.

Th17 cells that produce Interleukin IL-17 are pathogenic in many human diseases, including inflammatory bowel disease, but are, paradoxically, essential for maintaining the integrity of the intestinal barrier in a non-inflammatory state. However, the intracellular mechanisms that regulate distinct transcriptional profiles and functional diversity of Th17 cells remain unclear. Here we show Raftlin1, a lipid raft protein, specifically upregulates and forms a complex with RORγt in pathogenic Th17 cells.
