Efficacy of CycloMesh™+Ropivacaine in the treatment of uncomplicated inguinal hernia after the Lichtenstein procedure: Results of a prospective multicentric double-blind study.

Background: Twenty to 30% of patients undergoing inguinal hernia surgery (20 million patients per year worldwide) present early postoperative pain. The aim of this study was to assess the interest of a mesh (CycloMesh™, Cousin Biotech) soaked with ropivacaine for managing early postoperative pain.

Materials And Methods: This was a randomized, phase III, comparative superiority, double-blind, international multicenter study.

Comparison of surgical management and outcomes of acute right colic and sigmoid diverticulitis: a French national retrospective cohort study.

Background: Acute right colic diverticulitis (ARD) is less frequent in Western countries than acute sigmoid diverticulitis (ASD). We aimed to compare the management of ARD and ASD operated on in emergency.

Methods: All consecutive patients who had emergency surgery for ASD and ARD (2010-2021) were included in a retrospective, multicenter, cohort study.

Stabilization of the open conformation οf insulin-regulated aminopeptidase by a novel substrate-selective small-molecule inhibitor.

Insulin-regulated aminopeptidase (IRAP) is an enzyme with important biological functions and the target of drug-discovery efforts. We combined in silico screening with a medicinal chemistry optimization campaign to discover a nanomolar inhibitor of IRAP based on a pyrazolylpyrimidine scaffold. This compound displays an excellent selectivity profile versus homologous aminopeptidases, and kinetic analysis suggests it utilizes an uncompetitive mechanism of action when inhibiting the cleavage of a typical dipeptidic substrate.

Stenosis of the colorectal anastomosis after surgery for diverticulitis: A national retrospective cohort study.

Aim: The aim of this work was to investigate the association between early postoperative anastomotic leakage or pelvic abscess (AL/PA) and symptomatic anastomotic stenosis (SAS) in patients after surgery for left colonic diverticulitis.

Method: This is a retrospective study based on a national cohort of diverticulitis surgery patients carried out by the Association Française de Chirurgie. The assessment was performed using path analyses.

Islet cell stress induced by insulin-degrading enzyme deficiency promotes regeneration and protection from autoimmune diabetes.

Tuning of protein homeostasis through mobilization of the unfolded protein response (UPR) is key to the capacity of pancreatic beta cells to cope with variable demand for insulin. Here, we asked how insulin-degrading enzyme (IDE) affects beta cell adaptation to metabolic and immune stress. C57BL/6 and autoimmune non-obese diabetic (NOD) mice lacking IDE were exposed to proteotoxic, metabolic, and immune stress.

Risk factors for emergency surgery for diverticulitis: A retrospective multicentric French study at 41 hospitals.

Background: The observed increase in the incidence of complicated diverticulitis may lead to the performance of more emergency surgeries. This study aimed to assess the rate and risk factors of emergency surgery for sigmoid diverticulitis.

Method: The primary outcomes were the rate of emergency surgery for sigmoid diverticulitis and its associated risk factors.

Risk factors for severe morbidity and definitive stoma after elective surgery for sigmoid diverticulitis: a multicenter national cohort study.

Background: In the decision to perform elective surgery, it is of great interest to have data about the outcomes of surgery to individualize patients who could safely undergo sigmoid resection. The aim of this study was to provide information on the outcomes of elective sigmoid resection for sigmoid diverticular disease (SDD) at a national level.

Methods: All consecutive patients who had elective surgery for SDD (2010-2021) were included in this retrospective, multicenter, cohort study.

Right portal vein ligation is still relevant for left hemi-liver hypertrophy: results of a comparative study using a propensity score between right portal vein ligation and embolization.

Background: In two-stage hepatectomy for bilobar liver metastases from colorectal cancer, future liver remnant (FLR) growth can be achieved using several techniques, such as right portal vein ligation (RPVL) or right portal vein embolization (RPVE). A few heterogeneous studies have compared these two techniques with contradictory results concerning FLR growth. The objective of this study was to compare FLR hypertrophy of the left hemi-liver after RPVL and RPVE.

Real-life data comparing the efficacy of vigabatrin and oral steroids given sequentially or combined for infantile epileptic spasms syndrome.

Aims: The prognosis of Infantile epileptic spasm syndrome (IESS), relates to the underlying etiology and delay in controlling epileptic spasms. Based on the spasm-free rate, a randomized controlled trial has demonstrated the superiority of combining oral steroids and vigabatrin over oral steroids alone but confirmation in real-life conditions is mandatory.

Methods: We compared two real-life IESS cohorts: a multicenter, retrospective cohort of 40 infants treated with vigabatrin followed by a sequential (ST) addition of steroids, and a prospective, single-center cohort of 58 infants treated with an immediate combination of vigabatrin and steroids (CT).

Impact of the first wave of COVID-19 epidemy on the surgical management of sigmoid diverticular disease in France: National French retrospective study.

Objective: To analyze the surgical management of sigmoid diverticular disease (SDD) before, during, and after the first containment rules (CR) for the first wave of COVID-19.

Methods: From the French Surgical Association multicenter series, this study included all patients operated on between January 2018 and September 2021. Three groups were compared: A (before CR period: 01/01/18-03/16/20), B (CR period: 03/17/20-05/03/20), and C (post CR period: 05/04/20-09/30/21).

Pancreatic islet cell stress induced by insulin-degrading enzyme deficiency promotes islet regeneration and protection from autoimmune diabetes.

Appropriate tuning of protein homeostasis through mobilization of the unfolded protein response (UPR) is key to the capacity of pancreatic beta cells to cope with highly variable demand for insulin synthesis. An efficient UPR ensures a sufficient beta cell mass and secretory output but can also affect beta cell resilience to autoimmune aggression. The factors regulating protein homeostasis in the face of metabolic and immune challenges are insufficiently understood.

Cross-presentation by the others.

The critical role of conventional dendritic cells in physiological cross-priming of immune responses to tumors and pathogens is widely documented and beyond doubt. However, there is ample evidence that a wide range of other cell types can also acquire the capacity to cross-present. These include not only other myeloid cells such as plasmacytoid dendritic cells, macrophages and neutrophils, but also lymphoid populations, endothelial and epithelial cells and stromal cells including fibroblasts.

Benefit of a flash dose of corticosteroids in digestive surgical oncology: a multicenter, randomized, double blind, placebo-controlled trial (CORTIFRENCH).

Background: The modulation of perioperative inflammation seems crucial to improve postoperative morbidity and cancer-related outcomes in patients undergoing oncological surgery. Data from the literature suggest that perioperative corticosteroids decrease inflammatory markers and might be associated with fewer complications in esophageal, liver, pancreatic and colorectal surgery. Their benefit on cancer-related outcomes has not been assessed.

Role of protective stoma after primary anastomosis for generalized peritonitis due to perforated diverticulitis-DIVERTI 2 (a prospective multicenter randomized trial): rationale and design (nct04604730).

Background: Traditionally, patients with peritonitis Hinchey III and IV due to perforated diverticulitis were treated with Hartmann's procedure. In the past decade, resection and primary anastomosis have gained popularity over Hartmann's procedure and recent guidelines recommend Hartmann's procedure in two situations only: critically ill patients and in selected patients with multiple comorbidity (at high risk of complications). The protective stoma (PS) is recommended after resection with primary anastomosis, however its interest has never been studied.

Feasibility and Effectiveness of an Enhanced Recovery Program after Early Cholecystectomy for Acute Calculous Cholecystitis: A 2-Step Study.

Background: Enhanced recovery programs (ERPs) are associated with a lower morbidity rate and a shorter length of stay. The present study's objective was to determine whether an ERP is feasible and effective for patients undergoing early cholecystectomy for grade I or II acute calculous cholecystitis.

Study Design: A 2-step multicenter study was performed.

Impact of a procalcitonin-based algorithm on the quality of management of patients with uncomplicated adhesion-related small bowel obstruction assessed by a textbook outcome: a multicenter cluster-randomized open-label controlled trial.

Background: Acute adhesion-related small bowel obstruction (ASBO) is a common digestive emergency, accounting for 1 to 3% of all digestive emergencies. The efficacy of conservative management in this setting is a subject of debate, as it may delay the decision to perform surgery and increase the frequency of bowel resection (e.g.

Compromised mitochondrial quality control triggers lipin1-related rhabdomyolysis.

mutations are responsible for inherited recurrent rhabdomyolysis, a life-threatening condition with no efficient therapeutic intervention. Here, we conduct a bedside-to-bench-and-back investigation to study the pathophysiology of lipin1 deficiency. We find that lipin1-deficient myoblasts exhibit a reduction in phosphatidylinositol-3-phosphate close to autophagosomes and late endosomes that prevents the recruitment of the GTPase Armus, locks Rab7 in the active state, inhibits vesicle clearance by fusion with lysosomes, and alters their positioning and function.

Long-term outcomes of Hartmann's procedure versus primary anastomosis for generalized peritonitis due to perforated diverticulitis: follow-up of a prospective multicenter randomized trial (DIVERTI).

Background: Surgical management of Hinchey III and IV diverticulitis involves Hartmann's procedure (HP) or primary resection anastomosis (PRA) with or without fecal diversion. These procedures were evaluated in four randomized controlled trials. Early results from these trials demonstrated similar rates of complications but higher rates of colonic restoration after PRA than HP.

Are colorectal cancer patients at risk for COVID-19 infection during the postoperative period? The Covid-GRECCAR study.

Introduction: During the COVID-19 pandemic, cancer patients have been regarded as having a high risk of severe events if they are infected with SARS-CoV-2, particularly those under medical or surgical treatment. The aim of this study was to assess the posttreatment risk of infection by SARS-CoV-2 in a population of patients operated on for colorectal cancer 3 months before the COVID-19 outbreak and who after hospitalization returned to an environment where the virus was circulating.

Materials And Methods: This French, multicenter cohort study included consecutive patients undergoing elective surgery for colorectal cancer between January 1 and March 31, 2020, at 19 GRECCAR hospitals.

IRAP Endosomes Control Phagosomal Maturation in Dendritic Cells.

Dendritic cells (DCs) contribute to the immune surveillance by sampling their environment through phagocytosis and endocytosis. We have previously reported that, rapidly following uptake of extracellular antigen into phagosomes or endosomes in DCs, a specialized population of storage endosomes marked by Rab14 and insulin-regulated aminopeptidase (IRAP) is recruited to the nascent antigen-containing compartment, thereby regulating its maturation and ultimately antigen cross-presentation to CD8 T lymphocytes. Here, using IRAP DCs, we explored how IRAP modulates phagosome maturation dynamics and cross-presentation.
