Oncogenic Functions of Alternatively Spliced Isoform in Retroperitoneal Liposarcoma.

Retroperitoneal liposarcoma (RPLPS) is one of the most common histologic subtypes of soft tissue sarcoma (STS). Complete surgical resection remains the mainstay treatment, while the high rate of locoregional recurrence constitutes the predominant cause of mortality. Well-differentiated (WDLPS) and dedifferentiated (DDLPS) liposarcoma are the most frequent subtypes of RPLPS and present amplified MDM2 gene as a hallmark.

Three-dimensional models: from cell culture to Patient-Derived Organoid and its application to future liposarcoma research.

Liposarcoma is one of the most common soft tissue sarcomas, however, its occurrence rate is still rare compared to other cancers. Due to its rarity, experiments are an essential approach to elucidate liposarcoma pathobiology. Conventional cell culture-based research (2D cell culture) is still playing a pivotal role, while several shortcomings have been recently under discussion.

Prevention of G-Induced Effects on Vision and Consciousness During Simulated Suborbital Spaceflight.

Introduction: During centrifuge-simulated suborbital spaceplane flights, launch and re-entry frequently cause visual symptoms, and G-induced loss of consciousness can occur. G-related effects may be more prominent during re-entry from microgravity on actual flights. A modified anti-G maneuver that does not involve a breath strain and is suitable for members of the public may be effective against these effects.

Evaluating the cost-utility of ferric derisomaltose versus ferric carboxymaltose in patients with inflammatory bowel disease and iron deficiency anaemia in Norway.

Aims: Iron deficiency anemia (IDA) is among the most common extraintestinal sequelae of inflammatory bowel disease (IBD). Intravenous iron is often the preferred treatment in patients with active inflammation with or without active bleeding, iron malabsorption, or intolerance to oral iron. The aim of the present study was to evaluate the cost-utility of ferric derisomaltose (FDI) versus ferric carboyxymaltose (FCM) in patients with IBD and IDA in Norway.

Targeted transcriptomic analysis of well-differentiated and dedifferentiated liposarcoma reveals multiple dysregulated pathways including glucose metabolism, TGF-β, and HIF-1 signaling.

Liposarcoma is the most prevalent sarcoma in adults representing 20% of all sarcomas with well-differentiated/dedifferentiated among the most common subtypes represented. Despite multimodality treatment approaches, there has not been any appreciable change in survival benefit in the past 10 years. The future of targeted therapy for WD/DDLPS is promising with the intention to spare multi-visceral removal due to radical surgical resection.

Cost-Utility of Real-Time Continuous Glucose Monitoring versus Self-Monitoring of Blood Glucose in People with Insulin-Treated Type 2 Diabetes in Spain.

Objective: Management of advanced type 2 diabetes (T2D) typically involves daily insulin therapy alongside frequent blood glucose monitoring, as treatments such as oral antidiabetic agents are therapeutically insufficient. Real-time continuous glucose monitoring (rt-CGM) has been shown to facilitate greater reductions in glycated hemoglobin (HbA1c) levels and improvements in patient satisfaction relative to self-monitoring of blood glucose (SMBG). This study aimed to investigate the cost-utility of rt-CGM versus SMBG in Spanish patients with insulin-treated T2D.

Association of adverse events and quality of life in patients with unresectable hepatocellular carcinoma.

Purpose: Hepatocellular carcinoma (HCC) is the third-leading cause of cancer-related deaths globally. Patients are often diagnosed with advanced disease, in which systemic and locoregional therapies are commonly used as first-line treatment. Such treatments can cause adverse events (AEs) that negatively affect quality of life (QoL), which is particularly undesirable where prognosis is poor.

The Impact of Unrelated Future Medical Costs on Economic Evaluation Outcomes for Different Models of Diabetes.

Objective: This study leveraged data from 11 independent international diabetes models to evaluate the impact of unrelated future medical costs on the outcomes of health economic evaluations in diabetes mellitus.

Methods: Eleven models simulated the progression of diabetes and occurrence of its complications in hypothetical cohorts of individuals with type 1 (T1D) or type 2 (T2D) diabetes over the remaining lifetime of the patients to evaluate the cost effectiveness of three hypothetical glucose improvement interventions versus a hypothetical control intervention. All models used the same set of costs associated with diabetes complications and interventions, using a United Kingdom healthcare system perspective.

Lessons for Flying Astronauts with Disabilities Drawn from Experience in Aviation.

Accessible spaceflight may seem a distant concept. As part of a diverse European Space Agency funded Topical Team, we are working on the physiological feasibility of space missions being undertaken by people with physical disabilities. Here, the first activity of this team is presented in the form of key lessons learned from aviation to inform new work on space missions.

Use of neoadjuvant paclitaxel in breast angiosarcoma-Impact on surgical resection and response rates.

Objective: Breast angiosarcoma is a tumor that can arise as a primary breast tumor or in association with prior radiation therapy. Angiosarcomas are uniquely sensitive to paclitaxel. This study evaluated the impact neoadjuvant paclitaxel (NAC) therapy has on surgical outcomes, tumor recurrence, and survival in breast angiosarcomas.

Mechanical property estimation of sarcoma-relevant extracellular vesicles using transmission electron microscopy.

Analysis of single extracellular vesicles (EVs) has the potential to yield valuable label-free information on their morphological structure, biomarkers and therapeutic targets, though such analysis is hindered by the lack of reliable and quantitative measurements of the mechanical properties of these compliant nanoscale particles. The technical challenge in mechanical property measurements arises from the existing tools and methods that offer limited throughput, and the reported elastic moduli range over several orders of magnitude. Here, we report on a flow-based method complemented by transmission electron microscopy (TEM) imaging to provide a high throughput, whole EV deformation analysis for estimating the mechanical properties of liposarcoma-derived EVs as a function of their size.

ISG15 mediates the function of extracellular vesicles in promoting ovarian cancer progression and metastasis.

The interferon stimulated gene 15 (ISG15), a ubiquitin like protein and its conjugates have been implicated in various human malignancies. However, its role in ovarian cancer progression and metastasis is largely unknown. In high grade serous ovarian cancer (HGSOC), ascites is the major contributor to peritoneal metastasis.

Systematic Literature Review of Studies Reporting Measures of Functional Outcome or Quality of Life in People with Negative Symptoms of Schizophrenia.

Aim: Negative symptoms of schizophrenia (NSS) have been linked with poor functional outcomes. A literature review was performed to identify instruments used to assess functional outcomes and quality of life in clinical trials and observational studies conducted in groups of people with NSS.

Methods: Literature search strings were designed using Medical Subject Headings combined with free-text terms and searches were performed using the PubMed, Embase and the Cochrane Library databases.

Modelling the Costs of Sublingual Immunotherapy versus Subcutaneous Immunotherapy Based on Clinical Appointments and Impacts of Patient Travel in Sweden.

Aim: In Sweden, allergy immunotherapy (AIT) is available as either subcutaneous immunotherapy (SCIT) injections or sublingual immunotherapy (SLIT) tablets and is used to treat moderate-severe allergic rhinitis (AR). This study sought to determine direct and indirect annual costs stemming from treatment-related travel, appointments, waiting times and medication costs, before exploring likely CO emission-related cost-savings for 20,330 patients receiving SCIT or SLIT-tablets in Sweden.

Methods: A model was developed in Python to capture each category of costs in the target patient population.

Hypophosphatemia attenuates improvements in vitality after intravenous iron treatment in patients with inflammatory bowel disease.

Purpose: Iron deficiency anemia is common in people with inflammatory bowel disease (IBD), causing deterioration in quality of life, which can be reversed by treatment that increases iron stores and hemoglobin levels. The present post hoc analyses estimate health state utility values for patients with IBD after treatment with ferric derisomaltose or ferric carboxymaltose and evaluate the health domains driving the changes.

Methods: SF-36v2 responses were recorded at baseline and day 14, 35, 49, and 70 from 97 patients enrolled in the randomized, double-blind, PHOSPHARE-IBD trial (ClinicalTrials.

Extracellular Vesicle - MDM2-DNA as a Potential Liquid Biopsy Biomarker for Disease Identification in Retroperitoneal Liposarcoma.

Objective: We aimed to assess the levels of MDM2-DNA within extracellular vesicles (EVs) isolated from the serum of retroperitoneal liposarcoma (RLS) patients versus healthy donors, as well as within the same patients at the time of surgery versus post-operative surveillance visits. To determine whether EV-MDM2 may serve as a possible first-ever biomarker of liposarcoma recurrence.

Background: A hallmark of well-differentiated and de-differentiated (WD/DD) retroperitoneal liposarcoma is elevated MDM2 due to genome amplification, with recurrence rates of >50% even after complete resection.

Comparison of three-dimensional cell culture techniques of dedifferentiated liposarcoma and their integration with future research.

Dedifferentiated liposarcoma is a formidable sarcoma subtype due to its high local recurrence rate and resistance to medical treatment. While 2D cell cultures are still commonly used, 3D cell culture systems have emerged as a promising alternative, particularly scaffold-based techniques that enable the creation of 3D models with more accurate cell-stroma interactions. To investigate how 3D structures with or without the scaffold existence would affect liposarcoma cell lines growth morphologically and biologically.

Radiation therapy for retroperitoneal sarcoma: practice patterns in North America.

Background: The addition of radiation therapy (RT) to surgery in retroperitoneal sarcoma (RPS) remains controversial. We examined practice patterns in the use of RT for patients with RPS over time in a large, national cohort.

Methods: Patients in the National Cancer Database (2004-2017) who underwent resection of RPS were included.
