Glycogen drives tumour initiation and progression in lung adenocarcinoma.

Lung adenocarcinoma (LUAD) is an aggressive cancer defined by oncogenic drivers and metabolic reprogramming. Here we leverage next-generation spatial screens to identify glycogen as a critical and previously underexplored oncogenic metabolite. High-throughput spatial analysis of human LUAD samples revealed that glycogen accumulation correlates with increased tumour grade and poor survival.

Induced breeding failure alters movements, migratory phenology, and opportunities for pathogen spread in an urban gull population.

Background: Annual-cycle movements of wildlife are driven by a combination of intrinsic and extrinsic factors. In urban systems, management strategies to reduce human-wildlife interactions could also alter wildlife movement and distribution, with potential effects on key ecological processes such as pathogen spread.

Methods: To better understand how management actions interact with existing spatial dynamics to mediate wildlife movement patterns, we experimentally subjected urban-nesting yellow-legged gulls to induced breeding failure via egg-oiling.

Circulating causal protein networks linked to future risk of myocardial infarction.

Variations in blood protein levels have been associated with a broad spectrum of complex diseases, including atherosclerotic cardiovascular disease (ACVD). These associations highlight the intricate interplay between local (e.g.

The Risk of Postoperative Periprosthetic Femoral Fracture After Total Hip Arthroplasty Depends More on Stem Design Than Cement Use: An Analysis of National Health Data from England.

Background: In this study, we estimated the risk of surgically treated postoperative periprosthetic femoral fractures (POPFFs) associated with femoral implants frequently used for total hip arthroplasty (THA).

Methods: In this cohort study of patients who underwent primary THA in England between January 1, 2004, and December 31, 2020, POPFFs were identified from prospectively collected revision records and national hospital records. POPFF incidence rates, adjusting for potential confounders, were estimated for common stems.

Pro-inflammatory effects of inhaled Great Salt Lake dust particles.

Background: Climate change and human activities have caused the drying of marine environments around the world. An example is the Great Salt Lake in Utah, USA which is at a near record low water level. Adverse health effects have been associated with exposure to windblown dust originating from dried lakebed sediments, but mechanistic studies evaluating the health effects of these dusts are limited.

Evidence for microbially-mediated tradeoffs between growth and defense throughout coral evolution.

Background: Evolutionary tradeoffs between life-history strategies are important in animal evolution. Because microbes can influence multiple aspects of host physiology, including growth rate and susceptibility to disease or stress, changes in animal-microbial symbioses have the potential to mediate life-history tradeoffs. Scleractinian corals provide a biodiverse, data-rich, and ecologically-relevant host system to explore this idea.

The determinants of handwashing in humanitarian crisis setting during the COVID-19 pandemic: a multi-country analysis.

The Wash'Em process was developed to improve the design of handwashing behaviour change programmes during outbreaks and humanitarian crises. It aims to rapidly create evidence-based, contextualized handwashing programmes. Wash'Em was widely used during the COVID-19 pandemic.

Seagrass ecosystems reduce disease risk and economic loss in marine farming production.

Seaweed farming comprises over half of global coastal and marine aquaculture production by mass; however, the future of the industry is increasingly threatened by disease outbreaks. Nature-based solutions provided by enhancing functions of coinciding species or ecosystems offer an opportunity to increase yields by reducing disease outbreaks while conserving biodiversity. Seagrass ecosystems can reduce the abundance of marine bacterial pathogens, although it remains unknown whether this service can extend to reducing disease risk in a marine resource.

Genetic Architecture of Idiopathic Inflammatory Myopathies From Meta-Analyses.

Objective: Idiopathic inflammatory myopathies (IIMs, myositis) are rare systemic autoimmune disorders that lead to muscle inflammation, weakness, and extramuscular manifestations, with a strong genetic component influencing disease development and progression. Previous genome-wide association studies identified loci associated with IIMs. In this study, we imputed data from two prior genome-wide myositis studies and analyzed the largest myositis data set to date to identify novel risk loci and susceptibility genes associated with IIMs and its clinical subtypes.

A High-Resolution Microscopy System for Biological Studies of Cold-Adapted Species Under Physiological Conditions.

The Antarctic seabed harbors significant biodiversity, and almost 90% of oceanic environments are permanently below 5 °C (i.e., deep sea and polar regions).

Clinical stage IA non-small cell lung cancer with occult pathologic N1 and N2 disease after segmentectomy: does a completion lobectomy justify?

Objectives: When final pathology shows pathologic N1 or N2 disease after a pulmonary segmentectomy for early stage non-small cell lung cancer (NSCLC), completion of lobectomy could be considered and recommended as an option for treatment. We explored outcomes after segmentectomy for clinical stage IA NSCLC with occult pN1 or pN2 disease.

Methods: We identified clinical stage IA NSCLC undergoing segmentectomy or lobectomy from the National Cancer Database (NCDB) between 2010 and 2020.

Neurologic Outcomes in People With Multiple Sclerosis Treated With Immune Checkpoint Inhibitors for Oncologic Indications.

Background And Objectives: Immune checkpoint inhibitors (ICIs) are increasingly used against various cancers but are associated with immune-related adverse events (irAEs). Risk of irAEs may be higher in patients with certain preexisting autoimmune diseases, and these patients may also experience exacerbation of the underlying autoimmune disease following ICI initiation. People with multiple sclerosis (MS) have mostly been excluded from clinical trials of ICIs, so data on the safety of ICIs in MS are limited.

Magnetic Resonance Imaging Versus Computed Tomography Guidance for Stereotactic Body Radiotherapy in Prostate Cancer: 2-year Outcomes from the MIRAGE Randomized Clinical Trial.

It has been shown that magnetic resonance imaging (MRI) guidance versus computed tomography (CT) guidance for aggressive margin-reduction (AMR) for stereotactic body radiotherapy (SBRT) in prostate cancer reduces acute toxicity, but the longer-term benefits are unknown. We performed a secondary analysis of MIRAGE, a phase 3 randomized clinical trial of MRI-guided SBRT for prostate cancer, to determine whether AMR with MRI guidance significantly reduced 2-yr physician-scored or patient-reported toxic effects in comparison to CT guidance. The cumulative incidence of 2-yr physician-scored toxicity, defined as grade ≥2 genitourinary (GU) and gastrointestinal (GI) toxic effects according to Common Terminology Criteria for Adverse Events v4.

'This is PEEP' participatory qualitative study: learning from a provincial consultation and advisory group of people with lived and living experience of substance use in British Columbia, Canada.

Objectives: To summarise PEEP's (Professionals for Ethical Engagement of Peers-a group of consultants with lived and living experience of substance use) outputs and gain insights into PEEP's impact and suggestions for the future.

Design: Included an environmental scan to collate PEEP activities and outputs and a participatory qualitative design using thematic analysis.

Setting: British Columbia, Canada.

Anti-Sp4 and Anti-CCAR1 autoantibodies in UK vs. US patients with adult and juvenile-onset anti-TIF1ƴ-positive myositis.

Objectives: Anti-TIF1γ autoantibodies are associated with malignancy in adult-onset idiopathic inflammatory myopathy (IIM) and this risk is attenuated if patients are also positive for anti-specificity protein 4 (Sp4) or anti-cell division cycle apoptosis regulator protein 1 (CCAR1). In anti-TIF1γ positive US dermatomyositis (DM) patients, anti-Sp4 and anti-CCAR1 autoantibody frequencies are reported as 32% and 43% in adults and 9% and 19% in juveniles, respectively. This study aims to identify the frequency of anti-Sp4 and anti-CCAR1 in adult and juvenile UK anti-TIF1ƴ-positive myositis populations and report clinical associations.

Preferential occurrence of fast radio bursts in massive star-forming galaxies.

Fast radio bursts (FRBs) are millisecond-duration events detected from beyond the Milky Way. FRB emission characteristics favour highly magnetized neutron stars, or magnetars, as the sources, as evidenced by FRB-like bursts from a galactic magnetar, and the star-forming nature of FRB host galaxies. However, the processes that produce FRB sources remain unknown.

Enzyme-Responsive DNA Condensates.

Membrane-less compartments and organelles are widely acknowledged for their role in regulating cellular processes, and there is an urgent need to harness their full potential as both structural and functional elements of synthetic cells. Despite rapid progress, synthetically recapitulating the nonequilibrium, spatially distributed responses of natural membrane-less organelles remains elusive. Here, we demonstrate that the activity of nucleic-acid cleaving enzymes can be localized within DNA-based membrane-less compartments by sequestering the respective DNA or RNA substrates.

The incidence of postoperative periprosthetic femoral fracture following total hip replacement: An analysis of UK National Joint Registry and Hospital Episodes statistics data.

Background: Postoperative periprosthetic femoral fracture (POPFF) after total hip replacement (THR) requires complex surgery and is associated with a high morbidity, mortality, and cost. Although the United Kingdom based National Joint Registry (NJR) captures over 95% of THRs treated with revision, before June 2023 it did not capture POPFF treated with fixation. We aimed to estimate the incidence and epidemiology of POPFF treated with either surgery in England.

Tracheobronchoplasty for severe tracheobronchomalacia: a case-series of patients with acute and chronic critical comorbidities.

Objectives: There are little data within the literature regarding tracheobronchoplasty in the setting of the acute and chronically ill, morbidly obese or ventilator-dependent patients with tracheobronchomalacia. Short- and long-term outcomes are studied.

Methods: The series represents 12 tracheobronchomalacia patients with American Society of Anesthesiologists (ASA) physical status scores of 3-5.
