Emergency cancer diagnosis in Paris: A cross-sectional study using AP-HP data.

Many cancer patients are diagnosed following an emergency hospital admission in the 30 days preceding their diagnosis ('emergency presentation') and these patients have worse outcomes. Despite multiple international studies, there is only sparse evidence on emergency diagnosis of cancer in France. We examined the frequency of emergency presentation and its association with survival in patients with breast, lung, colon, rectal and pancreatic cancer, using data from the Paris Region University Hospitals (Assistance Publique Hôpitaux de Paris, AP-HP).

Clinical Safety and Efficacy of Hyaluronic Acid-Niacinamide-Tranexamic Acid Injectable Hydrogel for Multifactorial Facial Skin Quality Enhancement with Dark Skin Lightening.

Facial aging is a complex process manifesting as skin hyperpigmentation, textural irregularities, and a diminished elasticity, hydration, and evenness of tone. The escalating demand for minimally invasive aesthetic interventions has driven the development of advanced hydrogel-based injectable formulations. This clinical study assessed the safety and efficacy of Hydragel A1, an injectable hydrogel containing hyaluronic acid (HA), niacinamide, and tranexamic acid (TXA), designed to simultaneously address multiple facets of facial skin aging.

Hartmann's procedure versus primary anastomosis for Hinchey III or IV sigmoid diverticulitis: a propensity score analysis of a retrospective national cohort study.

Introduction:  Primary anastomosis with a diverting stoma (PA) has been evaluated relative to Hartmann's procedure (HP) for Hinchey III/IV peritonitis in four randomized trials, all of which lacked power. We aimed to evaluate the safety of PA for this indication in real-life settings.

Patients And Methods:  Patients who underwent surgery for Hinchey III/IV diverticulitis at 43 French centers from 2010 to 2021 were included in this retrospective multicenter study.

Minimally Invasive Spleen-Preserving Distal Pancreatectomy in Obese Patients: Factors Related to Clinically Relevant Pancreatic Fistula.

Background: Minimally invasive spleen-preserving distal pancreatectomy (MI-SPDP) provides superior outcomes compared with open surgery, with robotic techniques showing better short-term results than laparoscopic techniques, particularly in obese patients. This study aimed to evaluate the impact of the surgical approach on postoperative pancreatic fistula (POPF) incidence in obese patients undergoing MI-SPDP.

Methods: A retrospective analysis of obese patients from 16 international centres compared robotic (R-SPDP) and laparoscopic (L-SPDP) approaches.

Bicomponent Cutaneous Cell Therapy for Early Burn Care: Manufacturing Homogeneity and Epidermis-Structuring Functions of Clinical Grade FE002-SK2 Allogeneic Dermal Progenitor Fibroblasts.

The extracellular matrix (ECM), primarily composed of collagen and elastin synthesized by dermal fibroblasts, is critical for mesenchymal tissue integrity. Fibroblast phenotypes vary significantly with the anatomical location and developmental stage. Fetal skin, particularly prior to 14 weeks of gestation, exhibits a simplified structure compared to adult skin, characterized by a thin, loose dermal matrix and a single-layered epithelium.

Background: Studies evaluating the impact of the American Society of Anesthesiologists Physical status (ASA-PS) score on outcomes after liver resection (LR) are currently lacking. The aim was to evaluate the value of ASA-PS score on perioperative outcomes for laparoscopic liver resection (LLR).

Methods: This is a retrospective analysis of patients who underwent LLR from 1996 to 2018 at 29 French medical centers.

In Vitro Evaluation and Clinical Effects of a Regenerative Complex with Non-Cross-Linked Hyaluronic Acid and a High-Molecular-Weight Polynucleotide for Periorbital Treatment.

Skin aging is a complex and multifactorial process influenced by both intrinsic and extrinsic factors. The periorbital area of the face is particularly susceptible to premature aging signs due to its delicate skin structure, and is a major concern for many individuals. While hyaluronic acid (HA)-based dermal filler products are commonly used for periorbital rejuvenation, novel approaches to effectively locally address the visible signs of aging are available.

Objectives: To identify risk factors for conversion, develop a predictive Conversion Risk Score (CRS), and assess the association between conversion and severe postoperative complications.

Background: Conversion occurs in 15-30% of minimally invasive left pancreatectomies (MILP). Risk factors and potential negative impacts on postoperative outcomes are poorly described.

From Polydeoxyribonucleotides (PDRNs) to Polynucleotides (PNs): Bridging the Gap Between Scientific Definitions, Molecular Insights, and Clinical Applications of Multifunctional Biomolecules.

Polydeoxyribonucleotides (PDRNs) and polynucleotides (PNs) are similar DNA-derived biopolymers that have garnered significant scientific attention since the 1990s for their potential applications in wound healing and skin rejuvenation. These biopolymers exhibit a broad molecular weight (MW) range, typically spanning from 50 to 1500 kDa. However, recent studies have expanded this range to encompass fragments as small as 1 kDa and as large as 10,000 kDa.

Optimization and Standardization of Stable De-Epidermized Dermis (DED) Models for Functional Evaluation of Cutaneous Cell Therapies.

The human skin is a remarkable organ capable of extensive regeneration, especially after severe injuries such as burns and related wounds. The de-epidermized dermis (DED) model has become a valuable in vitro tool for skin regeneration studies, particularly for testing the mechanism of action and the efficacy of clinical cutaneous cell therapies. To further improve the quality and robustness of these applications, our study focused on optimizing and standardizing DED tissue preparation and storage, enhancing its effectiveness for clinical testing.

Sustainable Primary Cell Banking for Topical Compound Cytotoxicity Assays: Protocol Validation on Novel Biocides and Antifungals for Optimized Burn Wound Care.

Thorough biological safety testing of topical therapeutic compounds and antimicrobials is a critical prerequisite for appropriate cutaneous wound care. Increasing pathogen resistance rates to traditional antibiotics and antifungals are driving the development and registration of novel chemical entities. Although they are notably useful for animal testing reduction, the gold standard in vitro cytotoxicity assays in continuous cell lines (HaCaT keratinocytes, 3T3 fibroblasts) may be discussed from a translational relevance standpoint.

Conversion to open surgery in obese patients undergoing minimally invasive distal pancreatectomy: results from a multicenter analysis.

Background: Although minimally invasive distal pancreatectomy (MIDP) is considered a standard approach it still presents a non-negligible rate of conversion to open that is mainly related to some difficulty factors, as obesity. The aim of this study is to analyze the preoperative factors associated with conversion in obese patients with MIDP.

Methods: In this multicenter study, all obese patients who underwent MIDP at 18 international expert centers were included.
