The current landscape of stereotactic body radiation therapy for metastatic castration-resistant prostate cancer.

Background: The onset of castration-resistance is associated with dismal outcomes in patients with prostate cancer (PCa). Metastasis directed therapy has been investigated in multiple disease settings and may improve outcomes in selected patients. Our systematic review aims to summarize evidence with stereotactic body radiotherapy (SBRT) in castration-resistant prostate cancer (CRPC).

Reconstruction of the anterior chest wall using the internal mammary artery perforator flap (IMAP): About a series of 23 cases.

Background: The advent of propeller flaps has permitted new and less invasive coverage solutions for thoracic defects compared to conventional flaps. Through a retrospective analysis of our cases, we would like to show the advantages of the internal mammary artery perforator (IMAP) flap for anterior chest wall reconstruction.

Methods: We included patients who underwent anterior chest wall reconstruction with an IMAP propeller flap in the Toulouse University Hospital's plastic surgery department from January 2019 to December 2022.

Long-Term Pharmacokinetic Follow-Up of Abiraterone Acetate in Patients with Metastatic Castration-Resistant Prostate Cancer.

This ABIGENE pharmacokinetic (PK) study sought mainly to characterize the unchanged drug PK during long-term abiraterone acetate (AA) administration in advanced prostate cancer patients (81 patients). It was observed that individual AA concentrations remained constant over treatment time, with no noticeable changes during repeated long-term drug administration for up to 120 days. There was no correlation between AA concentrations and survival outcomes.

Restoring the Preoperative Phenotype According to the Coronal Plane Alignment of the Knee Classification After Total Knee Arthroplasty Leads to Better Functional Results.

Background: Mechanical alignment after total knee arthroplasty (TKA) is still widely used in the surgical community, but the alignment finally obtained by conventional techniques remains uncertain. The recent Coronal Plane Alignment of the Knee (CPAK) classification distinguishes 9 knee phenotypes according to constitutional alignment and joint line obliquity (JLO). The aim of this study was to assess the phenotypes of osteoarthritic patients before and after TKA using mechanical alignment and to analyze the influence of CPAK restoration on functional outcomes.

Assessment of the current and emerging criteria for the histopathological classification of lung neuroendocrine tumours in the lungNENomics project.

Background: Six thoracic pathologists reviewed 259 lung neuroendocrine tumours (LNETs) from the lungNENomics project, with 171 of them having associated survival data. This cohort presents a unique opportunity to assess the strengths and limitations of current World Health Organization (WHO) classification criteria and to evaluate the utility of emerging markers.

Patients And Methods: Patients were diagnosed based on the 2021 WHO criteria, with atypical carcinoids (ACs) defined by the presence of focal necrosis and/or 2-10 mitoses per 2 mm.

Internal mammary artery perforator flap for repair of an upper thoracic tracheo-oesophageal fistula.

Tracheoesophageal fistulas (TOF) following esophagectomy for esophageal cancer are rare but potentially fatal. There is no consensus on treatment between stenting and surgical repair, although the latter is associated with better distant survival. In surgical repair, the interposition of a flap improves healing by providing well-vascularized tissue and reinforcing the repair zone.

A rare case report of a primary lung cancer comprising adenocarcinoma and atypical carcinoid tumor, with the carcinoid component harboring rearrangement.

Background: The occurrence of pulmonary adenocarcinoma coexisting with atypical carcinoid tumors is a rare phenomenon. The presence of fusion in an atypical carcinoid component of a histologically mixed tumor is even more uncommon. Due to their infrequency, the origin and pathogenesis of these mixed tumors remain largely unknown.

Preictal dysfunctions of inhibitory interneurons paradoxically lead to their rebound hyperactivity and to low-voltage-fast onset seizures in Dravet syndrome.

Epilepsies have numerous specific mechanisms. The understanding of neural dynamics leading to seizures is important for disclosing pathological mechanisms and developing therapeutic approaches. We investigated electrographic activities and neural dynamics leading to convulsive seizures in patients and mouse models of Dravet syndrome (DS), a developmental and epileptic encephalopathy in which hypoexcitability of GABAergic neurons is considered to be the main dysfunction.

Exploring Iodide and Hydrogen Sulfide as ROS Scavengers to Delay Acute Rejection in MHC-Defined Vascularized Composite Allografts.

Vascularized composite allografts (VCA) face ischemic challenges due to their limited availability. Reperfusion following ischemia triggers oxidative stress and immune reactions, and scavenger molecules could mitigate ischemia-reperfusion injuries and, therefore, immune rejection. We compared two scavengers in a myocutaneous flap VCA model.

Feasibility of perforator flaps in Day surgery. A retrospective study through a two-years' experience.

Background: Day surgery is developing and its popularity is increasing for a variety of reasons: economic constraints, changes in professional practices, a greater adhesion of the patient. In an era of progress in surgical procedures, pedicled-perforator flaps reducing donor site morbidity and avoiding micro-anastomosis could take their place in Day surgery if planned and managed by an experienced team.

Methods: In the period January 2019 to January 2021, we performed perforator flaps for soft tissue coverage in ambulatory setting.

Adapted EXTREME regimen in the first-line treatment of fit, older patients with recurrent or metastatic head and neck squamous cell carcinoma (ELAN-FIT): a multicentre, single-arm, phase 2 trial.

Background: A standard treatment for fit, older patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) is yet to be established. In the previous EXTREME trial, few older patients were included. We aimed to evaluate the efficacy and tolerance of an adapted EXTREME regimen in fit, older patients with recurrent or metastatic HNSCC.

Secukinumab in adult patients with lichen planus: efficacy and safety results from the randomized placebo-controlled proof-of-concept PRELUDE study.

Background: Patients with lichen planus (LP) refractory to available therapies often experience a high disease burden, representing a population with a clear unmet need for new treatments.

Objectives: To evaluate the efficacy and safety of secukinumab 300 mg over 32 weeks in adult patients with biopsy-proven cutaneous LP (CLP), mucosal LP (MLP) or lichen planopilaris (LPP) that is inadequately controlled by topical corticosteroids.

Methods: PRELUDE was a randomized double-blind placebo-controlled phase II proof-of-concept study that enrolled patients with CLP, MLP or LPP.

Long-term Outcome of Risankizumab in Crohn's Disease: a Real-world GETAID Study.

Background & Aims: The aim of this study was to assess the long-term effectiveness and safety of risankizumab maintenance treatment in a large real-world cohort of patients with Crohn's Disease (CD).

Methods: From May 2021 to August 2023, all consecutive patients with CD treated with risankizumab in 25 GETAID centers have been retrospectively included. The primary endpoint was steroid-free clinical remission (Harvey Bradshaw Index [HBI] <5) at 52 weeks.

Neutrophil extracellular traps modulate chemotherapy efficacy and its adverse side effects.

Neutrophils, major regulator of innate immunity have recently emerged as key components of the tumor microenvironment. The role of neutrophils in cancer has been linked to their ability to form neutrophil extracellular traps (NETs), structures composed of decondensed DNA decorated with enzymes that are released into the extracellular space. Here, we discuss the pivotal roles of NETs, in influencing responses to chemotherapy and its severe adverse effect.

Efficacy of ferric carboxymaltose on haemoglobin response among older patients with gastrointestinal bleeding: a randomised clinical trial.

Background: Acute gastrointestinal bleeding (AGIB) is common in older patients but the use of iron in this context remains understudied.

Aims: This study aimed to evaluate prospectively the efficacy of ferric carboxymaltose to treat anaemia in older patients after AGIB.

Methods: This randomised double-blinded placebo-controlled clinical trial was conducted in 10 French centres.

Effect of a graded running race on lower limb muscle damage, jump performance and muscle soreness in men and women.

Purpose: Delayed structural and functional recovery after a 20 km graded running race was analyzed with respect to the sex effect.

Methods: Thirteen female and 14 male recreational runners completed the race and three test sessions: one before (PRE) and two after, once on Day 1 or 2 (D1-2) and then on Day 3 or 4 (D3-4). Muscle damage was assessed indirectly using ultrasonography to quantify changes in cross-sectional area (CSA) of 10 lower-limb muscles.

Whole-exome sequencing reveals an association of rs112065068 in TGOLN2 gene with distant metastasis of non-small cell lung cancer.

Early prediction and prevention of recurring illness is critical for improving the survival rates of patients with non-small cell lung cancer (NSCLC). Previously, we demonstrated that the presence of premalignant epithelial changes in the small bronchi distant to the primary tumor is associated with NSCLC progression: isolated basal cell hyperplasia (iBCH) indicates a high risk of distant metastasis, BCH combined with squamous metaplasia (BCH) - a high risk of locoregional recurrence. Here, we aimed to identify germline single nucleotide variants (SNVs) and insertions and deletions (InDels) associated with distant metastasis and locoregional recurrence in cases with iBCH and BCH using whole-exome sequencing of 172 NSCLC patients.

NETscape or NEThance: tailoring anti-cancer therapy.

Neutrophils, major regulators of innate immunity, have recently emerged as key components of the tumor microenvironment. The role of neutrophils in cancer has been linked to their ability to form neutrophil extracellular traps (NETs), structures composed of decondensed DNA decorated with enzymes that are released into the extracellular space. Here, we discuss the pivotal roles of NETs in influencing responses to anticancer therapies such as chemotherapy, radiotherapy, immunotherapy, and targeted therapy.

Revealing the Ferroptotic Phenotype of Medulloblastoma.

The interaction of iron and oxygen is an integral part of the development of life on Earth. Nonetheless, this unique chemistry continues to fascinate and puzzle, leading to new biological ventures. In 2012, a Columbia University group recognized this interaction as a central event leading to a new type of regulated cell death named "ferroptosis.

Sports and Immunity, from the recreational to the elite athlete.

The pivotal role of the immune system in physical activity is well-established. While interactions are complex, they tend to constitute discrete immune responses. Moderate intensity exercise causes leukocytosis with a mild anti-inflammatory cytokine profile and immunoenhancement.

The accessory vascularization of the tensor fasciae latae muscle: towards a new classification?

Purpose: The tensor fasciae latae (TFL) muscle is supplied by the lateral femoral circumflex artery (LCFA), arising from the deep femoral artery. However, it has been noted that there is also a consistent vascular anastomotic network. The aim of this study was to describe the accessory vascularization of the TFL muscle through a descriptive anatomical study, in order to hypothesize the feasibility of harvesting a TFL flap in the event of an injury to the main pedicle.
