Contemporary management of phyllodes tumours of the breast: proposal for recommendations from the UK Association of Breast Surgery.

Phyllodes tumours of the breast are rare fibroepithelial neoplasms classified histologically into benign, borderline, or malignant; each requiring different treatment strategies. The infrequency of presentation can result in diagnostic and management variability. The aim is to provide evidence-based or expert consensus recommendations for multidisciplinary teams managing patients with phyllodes tumours.

Direct-acting oral anticoagulant removal by intraoperative hemoadsorption in CABG and/or single valve surgery: interim analysis of the International Safe and Timely Antithrombotic Removal (STAR) registry.

Objective: Patients on direct-acting oral anticoagulants (DOACs) are at high risk of perioperative bleeding complications. Intraoperative hemoadsorption is a novel strategy to reduce perioperative bleeding in patients on DOACs undergoing non-deferable cardiac surgery. The international STAR-registry reports real-world clinical outcomes associated with this application.

Study protocol: multi-centre, randomised controlled clinical trial exploring stromal targeting in locally advanced pancreatic cancer; STARPAC2.

Background: Pancreatic cancer (PDAC: pancreatic ductal adenocarcinoma, the commonest form), a lethal disease, is best treated with surgical excision but is feasible in less than a fifth of patients. Around a third of patients presentlocally advanced, inoperable, non-metastatic (laPDAC), whose stadrd of care is palliative chemotherapy; a small minority are down-sized sufficiently to enable surgical excision. We propose a phase II clinical trial to test whether a combination of standard chemotherapy (gemcitabine & nab-Paclitaxel: GEM-NABP) and repurposing All Trans Retinoic Acid (ATRA) to target the stroma may extend progression-free survival and enable successful surgical resection for patients with laPDAC, since data from phase IB clinical trial demonstrate safety of GEM-NABP-ATRA combination to patients with advanced PDAC with potential therapeutic benefit.

Physiochemical and functional evaluation of the first-in-class anti-cancer IgE antibody drug, MOv18, through process development and good manufacturing practice production.

Antibodies used for cancer therapy are monoclonal IgGs, but tumor-targeting IgE antibodies have shown enhanced effector cell potency against cancer in preclinical models. Research-grade recombinant IgE antibodies have been generated and studied for several decades. The recent Phase 1 clinical trial of the first-in-class MOv18 IgE, however, necessitated the inaugural process development and scaled manufacture of a recombinant IgE to clinical quality standards.

Global linear accelerator requirements and personalised country recommendations: a cross-sectional, population-based study.

Background: The Linear Accelerator Shortage Index (LSI) is a practical tool for prioritising the deployment of linear accelerators (LINACs) in various regions within a country. The LSI reflects the ratio of LINAC demand to current availability. The aim of this study was to use the LSI to predict global LINAC needs and classify countries according to the degree of radiotherapy shortage (LINAC shortage grade).

Assessment of complications and success rates of Percutaneous nephrolithotomy: single tract . multi tract approaches.

Purpose: The objective of this study was to assess the success and complication rates of single-tract access . multi-tract percutaneous nephrolithotomy (PNL).

Material And Methods: The medical records of consecutive patients who underwent PNL for staghorn, partial staghorn, and complex kidney stones between 2014 and 2022 were retrospectively reviewed.

Structural changes in troponin during activation of skeletal and heart muscle determined in situ by polarised fluorescence.

Calcium binding to troponin triggers the contraction of skeletal and heart muscle through structural changes in the thin filaments that allow myosin motors from the thick filaments to bind to actin and drive filament sliding. Here, we review studies in which those changes were determined in demembranated fibres of skeletal and heart muscle using fluorescence for in situ structure (FISS), which determines domain orientations using polarised fluorescence from bifunctional rhodamine attached to cysteine pairs in the target domain. We describe the changes in the orientations of the N-terminal lobe of troponin C (TnC) and the troponin IT arm in skeletal and cardiac muscle cells associated with contraction and compare the orientations with those determined in isolated cardiac thin filaments by cryo-electron microscopy.

IL-25 Enhances B Cell Responses in Type 2 Inflammation Through IL-17RB Receptor.

Background: Alarmin cytokine IL-25 promotes type 2 inflammatory responses in disorders such as asthma and chronic rhinosinusitis with nasal polyps (CRSwNP) and known targets include ILC2 and Th2 cells. However, other cellular targets for IL-25 remain poorly defined.

Objective: To investigate induction and expression of IL-25 receptor (IL-17RB) by B cells and evaluate responsiveness of IL-17RB-expressing B cells to IL-25 in vitro.

Acute kidney injury.

Acute kidney injury (AKI) is a common, heterogeneous, multifactorial condition, which is part of the overarching syndrome of acute kidney diseases and disorders. This condition's incidence highest in low-income and middle-income countries. In the short term, AKI is associated with increased mortality, an increased risk of complications, extended stays in hospital, and high health-care costs.

International Expert-Based Consensus Definition, Classification Criteria, and Minimum Data Elements for Osteoradionecrosis of the Jaw: An Inter-Disciplinary Modified Delphi Study.

Purpose: Osteoradionecrosis of the jaw (ORNJ) is a severe iatrogenic disease characterized by bone death after radiation therapy (RT) to the head and neck. With over 9 published definitions and at least 16 classification systems, the true incidence and severity of ORNJ are obscured by lack of a standard for disease definition and severity assessment, leading to inaccurate estimation of incidence, reporting ambiguity, and likely under-diagnosis worldwide. This study aimed to achieve consensus on an explicit definition and phenotype of ORNJ and related precursor states through data standardization to facilitate effective diagnosis, monitoring, and multidisciplinary management of ORNJ.

Bi-allelic KICS2 mutations impair KICSTOR complex-mediated mTORC1 regulation, causing intellectual disability and epilepsy.

Nutrient-dependent mTORC1 regulation upon amino acid deprivation is mediated by the KICSTOR complex, comprising SZT2, KPTN, ITFG2, and KICS2, recruiting GATOR1 to lysosomes. Previously, pathogenic SZT2 and KPTN variants have been associated with autosomal recessive intellectual disability and epileptic encephalopathy. We identified bi-allelic KICS2 variants in eleven affected individuals presenting with intellectual disability and epilepsy.

Programming of synthetic regulatory DNA for cell-type targeting in humans.

In a recent study in Nature, Gosai et al. introduce a framework to engineer and validate synthetic DNA regulatory elements showing cell-type-specific activity in human cell lines, closing the distance to the machine-driven design of functional regulatory sequences with therapeutic applications in humans.

Large-scale evaluation of outcomes after a genetic diagnosis in children with severe developmental disorders.

Purpose: We sought to evaluate outcomes for clinical management after a genetic diagnosis from the Deciphering Developmental Disorders study.

Methods: Individuals in the Deciphering Developmental Disorders study who had a pathogenic/likely pathogenic genotype in the DECIPHER database were selected for inclusion ( = 5010). Clinical notes from regional clinical genetics services notes were reviewed to assess predefined clinical outcomes relating to interventions, prenatal choices, and information provision.

Current and novel biomarkers in cardiogenic shock.

Cardiogenic shock (CS) carries a 30-50% in-hospital mortality rate, with little improvement in outcomes in the last decade. Challenges in improving outcomes are closely linked to the frequent late presentation or diagnosis of CS where the 'point of no return' has often passed, leading to haemodynamic dysregulation, progressive myocardial depression, hypotension, and a downward spiral of hypoperfusion, organ dysfunction and decreasing myocardial function, driven by inflammation and metabolic derangements. Novel therapeutic interventions may have varying efficacy depending on the type and stage of shock in which they are applied.

Compact and cGMP-compliant automated synthesis of [F]FSPG on the Trasis AllinOne™.

Background: (S)-4-(3-F-Fluoropropyl)-ʟ-glutamic acid ([F]FSPG) is a positron emission tomography radiotracer used to image system x, an antiporter that is upregulated in several cancers. Not only does imaging system x with [F]FSPG identify tumours, but it can also provide an early readout of response and resistance to therapy. Unfortunately, the clinical production of [F]FSPG has been hampered by a lack of robust, cGMP-compliant methods.
