The spatial organization of cDC1 with CD8+ T cells is critical for the response to immune checkpoint inhibitors in melanoma patients.

Dendritic cells (DCs) are promising targets for cancer immunotherapies because of their central role in the initiation and control of immune responses. The rare cDC1 population is of particular interest because of its remarkable ability to cross-present antigens (Ag) to CD8+ T cells, to promote Th1 cell polarization and NK cell activation and recruitment. However, the spatial organization and specific functions of cDC1s in response to immunotherapy remain to be clearly characterized in human tumors.

Circulating Endocannabinoids Are Associated with Mental Alertness During Ultra-Endurance Exercise.

Ultra-endurance exercise events result in central fatigue, impacting on mental alertness and decision making. Endocannabinoids are typically elevated during endurance exercise and have been implicated in central processes such as learning and memory, but their role in central fatigue has never been studied. Twenty-four recreational male ultrarunners participated in a 100-km trail run, and 18 of them completed at least 60 km and were included in the analyses.

When to stop immunotherapy for advanced melanoma: the emulated target trials.

Background: Immune checkpoint inhibitors (ICIs) have demonstrated their efficacy with a 7.5-year overall survival (OS) close to 50% for advanced stages. The design of clinical trials provides for treatment until progression or toxicity, or for a maximum duration of two years.

Three-Year Overall Survival With Nivolumab Plus Relatlimab in Advanced Melanoma From RELATIVITY-047.

Nivolumab plus relatlimab demonstrated a statistically significant improvement in progression-free survival (PFS), along with a clinically meaningful, but not statistically significant improvement in overall survival (OS) and a numerically higher objective response rate (ORR) compared with nivolumab in the RELATIVITY-047 trial (ClinicalTrials.gov identifier: NCT03470922). We report updated descriptive efficacy and safety results from RELATIVITY-047 with a median follow-up of 33.

Methods of nivolumab administration in advanced melanoma: A comparison of patients' clinical outcomes treated with flat dose or weight-adjusted dose, a multicenter observational study.

Background: Nivolumab obtained approval in advanced melanoma (AM) with weight-adjusted dose (WAD) administration (3 mg/kg/2 weeks). In 2018, the dosage regimen was changed to flat dose (FD) administration (240 mg/2 weeks or 480 mg/4 weeks) based on a modeling study, without clinical data.

Methods: AM patients have been prospectively included in the French national multicenter MelBase database since 2013.

The CB1 antagonist Rimonabant improves muscle regeneration and remodels the inflammatory and endocannabinoid profile upon injury in male mice.

Skeletal muscle regeneration upon injury requires timely activation of inflammatory, myogenic, fibrotic, apoptotic and anabolic systems. Optimization of these features might improve the recovery process. Whereas recent data indicate that the endocannabinoid system, and more particularly cannabinoid receptor 1 (CB1) antagonism, is involved in the regulation of inflammatory, myogenic, fibrotic, apoptotic and anabolic pathways, it was never studied whether CB1 antagonism can improve muscle regeneration.

[Acute kidney injury in cancer patients receiving immune checkpoint inhibitor therapy-shared guidelines of FITC/SFNDT].

Cancer treatments have been dramatically modified by the introduction and the development of immunological checkpoint inhibitors (ICI). These treatments have many side effects, including acute kidney injury (AKI). Their combination with other treatments makes the diagnosis complex.

The efficacy and safety of first-line metastatic melanoma treatment with ipilimumab + nivolumab versus nivolumab in a real-world setting.

Background: The Checkmate 067 randomized controlled trial, published in 2015, demonstrated improved progression-free survival and numerically, although not statistically, superior overall survival for ipilimumab + nivolumab. The objective of this study was to compare the efficacy and safety of nivolumab to ipilimumab + nivolumab as first-line treatment for metastatic melanoma in a real-world setting.

Methods: Patients were prospectively included in the French Melbase cohort from 2013 to 2022.

Real-World Pattern-of-Care Analysis of Primary Cutaneous Lymphomas Radiation Therapy Among European Organisation for Research and Treatment of Cancer Members.

Purpose: We aim to determine the current treatment patterns and recommendations among physicians for cutaneous lymphomas and to identify the types of skin lymphomas for which existing radiation regimens need improvement.

Methods And Materials: A questionnaire from the European Organisation for Research and Treatment of Cancer was distributed to all members of the Cutaneous Lymphoma Tumour Group and Radiation Oncology Scientific Council. This online survey included 13 questions regarding treatment practices for patients with cutaneous lymphoma.

Synergistic effect between denosumab and immune checkpoint inhibitors (ICI)? A retrospective study of 268 patients with ICI and bone metastases.

Background: Bone metastasis is a significant concern in advanced solid tumors, contributing to diminished patient survival and quality of life due to skeletal-related events (SREs). Denosumab (DMAB), a monoclonal antibody targeting the receptor activator of nuclear factor kappa-B ligand (RANKL), is used to prevent SREs in such cases. The RANK/RANKL axis, crucial in immunological processes, has garnered attention, especially with the expanding use of immune checkpoint inhibitors (ICI) in modern oncology.

CITROBACTER KOSERI SKIN AND SOFT TISSUE INFECTION COMPLICATED BY ABSCESS FORMATION: A CASE REPORT AND A REVIEW OF LITERATURE.

Citrobacter koseri (C. koseri) can lead to severe infections in the neonates, elderly and immunocompromised patients. We describe the first reported case of an axillary abscess due to C.

The molecular signature of the peripheral cannabinoid receptor 1 antagonist AM6545 in adipose, liver and muscle tissue.

The endocannabinoid system plays an important role in the regulation of metabolism, growth and regeneration of peripheral tissues, including liver, adipose and muscle tissue. Studies in cells, rodents and humans showed that cannabinoid receptor 1 (CB) antagonist treatment is an effective strategy to improve features of metabolic health such as substrate metabolism, at least in models of metabolic dysregulation. However, acute signaling events that might induce these metabolic adaptations are not understood.

Adjuvant pembrolizumab versus placebo in resected stage III melanoma (EORTC 1325-MG/KEYNOTE-054): long-term, health-related quality-of-life results from a double-blind, randomised, controlled, phase 3 trial.

Background: In the European Organisation for Research and Treatment of Cancer (EORTC) 1325-MG/KEYNOTE-054 study, adjuvant pembrolizumab improved recurrence-free survival and distant-metastasis-free survival in patients with resected stage III melanoma. Earlier results showed no effect of pembrolizumab on health-related quality of life (HRQOL). Little is known about HRQOL after completion of treatment with pembrolizumab, an important research area concerning patients who are likely to become long-term survivors.

Pustular mycosis fungoides has a poor outcome: a multicentric clinicopathological and molecular case series.

Background: Mycosis fungoides (MF) usually has an indolent course. However, some patients develop more aggressive disease and few prognostic parameters have been identified. Isolated cases of pustular MF (pMF) suggest an unfavourable prognosis.

Receptors and Signaling Pathways Controlling Beta-Cell Function and Survival as Targets for Anti-Diabetic Therapeutic Strategies.

Preserving the function and survival of pancreatic beta-cells, in order to achieve long-term glycemic control and prevent complications, is an essential feature for an innovative drug to have clinical value in the treatment of diabetes. Innovative research is developing therapeutic strategies to prevent pathogenic mechanisms and protect beta-cells from the deleterious effects of inflammation and/or chronic hyperglycemia over time. A better understanding of receptors and signaling pathways, and of how they interact with each other in beta-cells, remains crucial and is a prerequisite for any strategy to develop therapeutic tools aimed at modulating beta-cell function and/or mass.

Outcomes With Postrecurrence Systemic Therapy Following Adjuvant Checkpoint Inhibitor Treatment for Resected Melanoma in CheckMate 238.

Purpose: In phase III CheckMate 238, adjuvant nivolumab significantly improved recurrence-free survival compared with ipilimumab in patients with resected stage IIIB-C/IV melanoma without a significant difference in overall survival (OS). Here, we investigate progression-free survival (PFS) and OS after postrecurrence systemic therapy.

Patients And Methods: Patients 15 years or older with resected stage IIIB-C/IV melanoma were stratified by stage and tumor PD-L1 status and randomly assigned to receive nivolumab 3 mg/kg every 2 weeks, or ipilimumab 10 mg/kg every 3 weeks for four doses and then every 12 weeks for 1 year or until disease recurrence, unacceptable toxicity, or withdrawal of consent.

Palmitoylethanolamide Does Not Affect Recovery from Exercise-Induced Muscle Damage in Healthy Males.

Introduction: Strenuous eccentric exercise (EE) induces microstructural muscle damage, which decreases muscle performance. Palmitoylethanolamide (PEA) exerts analgesic and anti-inflammatory effects in clinical pain conditions and preclinical models of experimentally induced inflammation. This might hold clues for improved recovery from EE.
