Article Synopsis
  • The study investigates how cancer cells influence the fitness of surrounding tumor microenvironment (TME) cells through a mechanism involving a long non-coding RNA called Tu-Stroma, which alters the expression of Flower isoforms, impacting their growth advantage.
  • The expression of Flower Win isoforms in cancer cells enhances their dominance over TME cells that express Flower Lose isoforms, leading to reduced fitness in the TME.
  • Targeting Flower proteins with a humanized monoclonal antibody in mice has shown promising results, significantly reducing cancer growth and metastasis while improving survival rates and protecting organs from potential lesions.

Background: Animal-assisted interventions (AAI) can provide psychological support to critical care patients during their intensive care unit (ICU) admission. However, there are currently no data on AAI services across UK ICUs. The current study therefore aims to (i) determine how many ICUs in the UK offer services, (ii) characterise available services and (iii) explore and review local documentation for service oversight.

Objective: National approaches to the routine assessment of palliative care patients improve patient outcomes. However, validated tools and a national methodology for this are lacking in Mainland China. The Australian Palliative Care Outcomes Collaboration (PCOC) model is a well-established national program aimed at improving the quality of palliative care based on point-of-care outcomes assessment.

Coccidiomycosis is a regional disease with global importance, with both an expanding endemic area and population, as well as increasing travel. Although unusual, it should be considered in patients with a travel history to endemic areas, even when immunocompetent and outside the usual incubation period. We present a case of isolated ankle septic arthritis which required an aggressive multidisciplinary surgical approach as well as antibiotic therapy.

Article Synopsis
  • - Airway macrophages (AM) are key immune cells in the lungs that help protect against infections, making them important for targeted therapies aimed at enhancing immune responses.
  • - The study investigates how different types of macrophages respond to signaling molecules (IFN-γ and IL-4) that represent immune responses in the lungs, finding that AM rely heavily on glycolysis for their functions, especially in cytokine production.
  • - Results show that AM exhibit unique metabolic responses and functional plasticity compared to monocyte-derived macrophages (MDM), suggesting that AM could be effective targets for new inhaled treatments for lung diseases.

We hypothesized that phenotyping patients using a combination of resting peripheral venous pressure (PVP) and N-terminal pro-brain natriuretic peptide (NT-proBNP) would predict invasive Fontan haemodynamics. Accordingly, 35 adults with a history of Fontan palliation were categorized into 3 groups according to PVP and NT-proBNP values: normal, ↑NT-proBNP (≥300 pg/dL) or ↑PVP (≥15 mm Hg), and ↑PVP+↑NT-proBNP. Those in the normal values group universally had normal resting pulmonary artery wedge and Fontan pressures, with a single patient having abnormal exercise values; conversely, all patients in the ↑PVP+↑NT-proBNP group had increased resting Fontan or pulmonary artery wedge pressures, with those in the ↑NT-proBNP or ↑PVP group constituting an intermediate group.

In this paper, we explore the usage of decision aids, patient information leaflets (PILs), videos, social media and modern technology to empower patients and enable shared decision-making (SDM). It explores the role of enhanced consent processes in urology. A re-evaluation of the conventional consent process is required towards more patient-centred care and SDM, which prioritises patient education and understanding of their medical conditions and treatment pathways.

Introduction: With the implementation of low-dose computed tomography screening, multiple pulmonary tumor nodules are diagnosed with increasing frequency and the selection of surgical treatments versus systemic therapies has become challenging on a daily basis in clinical practice. In the presence of multiple carcinomas, especially adenocarcinomas, pathologically determined to be of pulmonary origin, the distinction between separate primary lung carcinomas (SPLCs) and intrapulmonary metastases (IPMs) is important for staging, management, and prognostication.

Methods: We systemically reviewed various means that aid in the differentiation between SPLCs and IPMs explored by histopathologic evaluation and molecular profiling, the latter includes DNA microsatellite analysis, array comparative genomic hybridization, TP53 and oncogenic driver mutation testing and, more recently, with promising effectiveness, next-generation sequencing comprising small- or large-scale multi-gene panels.

Pilot study on the in-vitro effect of radiation therapy on bending stiffness of intramedullary photodynamic implants.

J Orthop Surg Res

November 2024

Division of Orthopaedic Oncology, Department of Orthopaedic Surgery, Massachusetts General Hospital, Harvard Medical School, Boston, MA, USA.

Photodynamic implants are an increasingly popular minimally invasive option for the surgical treatment of metastatic bone disease. Following surgery, adjuvant radiation therapy (RT) is frequently administered to achieve better disease control and improve patient quality of life, but the role of RT in implant failures associated with photodynamic implants remains unclear. The aim of this study is to determine if the therapeutic RT range of 10-50 Gy affects the biomechanical properties of photodynamic implants.

Public health practitioners rely on timely surveillance data for planning and decision-making; however, surveillance data are often subject to delays. Epidemic trend categories, based on time-varying effective reproductive number (R) estimates that use nowcasting methods, can mitigate reporting lags in surveillance data and detect changes in community transmission before reporting is completed. CDC analyzed the performance of epidemic trend categories for COVID-19 during summer 2024 in the United States and at the state level in New Mexico.

Background: In BRAF-mutated high-risk melanoma, targeted therapy (BRAF/MEK inhibitors) and checkpoint inhibitor (CPI) immunotherapy have durable benefits as first-line (1L) adjuvant therapy. Based on differing action mechanisms of BRAF/MEK inhibitors and CPI immunotherapies, there is interest in evaluating the activity of 2L adjuvant targeted therapy in decreasing the risk of subsequent recurrence after repeat resection following relapse on/after 1L adjuvant CPI.

Patients And Methods: This was a retrospective review of BRAF V600-mutated resected stage III/IV melanoma patients in the United States, Australia, and The Netherlands who received 1L adjuvant CPI immunotherapy, relapsed locoregionally/distantly, were again resected to no evidence of disease, and received dabrafenib/trametinib (dab/tram) as 2L adjuvant therapy.
