Investigating the prognostic impact of NY-ESO-1 expression and HLA subtypes in metastatic synovial sarcoma.

Background: To better understand the importance of the New York esophageal squamous cell carcinoma 1 (NY-ESO-1) and human leukocyte antigen (HLA) subtypes in treatment decision-making, further investigation of their prevalence and prognostic impact among patients with metastatic synovial sarcoma (mSS) is needed.

Patients And Methods: This was a retrospective clinico-biological cohort study of adults with mSS. Patient data were collected from the French Sarcoma Group NetSARC database and supplemented by electronic medical records.

Successful pregnancy after 10 consecutive failures in a liver transplant patient with advanced kidney failure.

We report a successful, albeit complicated pregnancy with a live-born healthy baby at 28 weeks' gestation, after 10 pregnancy failures, in a 39-year-old patient with a history of liver transplantation and chronic kidney disease with hypertension and proteinuria. Multidisciplinary management (obstetrician, nephrologist and hepatology transplant specialist) allowed close monitoring, adaptation of immunosuppressive treatments and strict control of fetal growth. The onset of preeclampsia at 28 weeks' gestation led to a cesarean section, resulting in the birth of a healthy 830 g boy, with subsequent normal development.

Pathogenic variants in HGF give rise to childhood-to-late onset primary lymphoedema by loss of function.

Developmental and functional defects in the lymphatic system are responsible for primary lymphoedema (PL). PL is a chronic debilitating disease caused by increased accumulation of interstitial fluid, predisposing to inflammation, infections and fibrosis. There is no cure, only symptomatic treatment is available.

Development and validation of a composite score to predict severe forms of ischemic colitis.

Objective: To develop a simple scoring system in order to predict the risk of severe (death and/or surgery) ischemic colitis METHODS: In this retrospective study, 205 patients diagnosed with ischemic colitis in a tertiary hospital were consecutively included over a 6-year period. The study sample was sequentially divided into a training cohort (n = 103) and a validation cohort (n = 102). In the training cohort, multivariable analysis was used to identify clinical, biological, and CT variables associated with poor outcome and to build a risk scoring system.

Efficacy and Safety of a Hyaluronic Acid-Containing Cream in the Treatment of Chronic, Venous, or Mixed-Origin Leg Ulcers: A Prospective, Multicenter Randomized Controlled Trial.

Introduction: Topical applications of hyaluronic acid (HA)-containing formulations, based on the complex and vital role of HA in all stages of the wound-healing process, are routinely used with standard therapy to promote faster healing of chronic wounds. However, evidence to guide clinical decisions on the use of topical HA in the healing of vascular leg ulcers is limited.

Objective: This study compared the efficacy and safety of topical application of a hyaluronic acid cream vs a neutral comparator (identical cream without HA) in treating subjects with chronic leg ulcers of vascular origin.

Short-term Outcomes After Spleen-preserving Minimally Invasive Distal Pancreatectomy With or Without Preservation of Splenic Vessels: A Pan-European Retrospective Study in High-volume Centers.

Objective: To compare short-term clinical outcomes after Kimura and Warshaw MIDP.

Background: Spleen preservation during distal pancreatectomy can be achieved by either preservation (Kimura) or resection (Warshaw) of the splenic vessels. Multicenter studies reporting outcomes of Kimura and Warshaw spleen-preserving MIDP are scarce.

Antibodies to the Caspr1/contactin-1 complex in chronic inflammatory demyelinating polyradiculoneuropathy.

Previous studies have described the clinical, serological and pathological features of patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and antibodies directed against the paranodal proteins neurofascin-155, contactin-1 (CNTN1), contactin-associated protein-1 (Caspr1), or nodal forms of neurofascin. Such antibodies are useful for diagnosis and potentially treatment selection. However, antibodies targeting Caspr1 only or the Caspr1/CNTN1 complex have been reported in few patients with CIDP.

Efficacy and Safety of a Hyaluronic Acid-Containing Gauze Pad in the Treatment of Chronic Venous or Mixed-Origin Leg Ulcers: A Prospective, Multicenter, Randomized Controlled Trial.

Introduction: Hyaluronic acid (HA)-containing formulations routinely are utilized along with standard therapy to promote faster healing of chronic wounds; evidence to guide clinical decisions on the use of topical HA in the healing of vascular leg ulcers is limited.

Objective: This study compared the efficacy and safety of an HA-impregnated gauze pad with an identical gauze pad without HA in the treatment of chronic leg ulcers of vascular origin.

Materials And Methods: A prospective, multicenter, multinational, parallel-group, randomized, double-blind, clinical study was conducted between June 13, 2017, and December 31, 2018.

Can We Predict Individual Concentrations of Tacrolimus After Liver Transplantation? Application and Tweaking of a Published Population Pharmacokinetic Model in Clinical Practice.

Background: Various population pharmacokinetic models have been developed to describe the pharmacokinetics of tacrolimus in adult liver transplantation. However, their extrapolated predictive performance remains unclear in clinical practice. The purpose of this study was to predict concentrations using a selected literature model and to improve these predictions by tweaking the model with a subset of the target population.

Identification of factors associated with aggressive end-of-life antitumour treatment: retrospective study of 1282 patients with cancer.

Objective: Antitumour treatment in the last 2 weeks of death (ATT-W2) and a new regimen of ATT within 30 days of death (NATT-M1) are considered as aggressive end-of-life (EOL) care. We aimed to assess factors associated with inappropriate use of antitumour treatment (ATT) at EOL.

Methods: Data of patients with cancer who died in 2013, 2015, 2017 and 2019 in a single for-profit cancer centre were retrospectively analysed.

Assessing pain in critically ill brain-injured patients: a psychometric comparison of 3 pain scales and videopupillometry.

Three clinical scales (the Nociception Coma Scale adapted for Intubated patients [NCS-I], its Revised version [NCS-R-I], and the Behavioral Pain Scale [BPS]) and videopupillometry were compared for measuring pain in intubated, noncommunicating, critically ill, brain-injured patients. Pain assessment was performed before, during, just after, and 5 minutes after 3 procedures: the reference non-nociceptive procedure (assessment of the Richmond Agitation Sedation Scale) and 2 nociceptive procedures (turning and tracheal suctioning). The primary endpoint was construct validity (discriminant and criterion validation), determined by comparing pain measurements between different times/procedures.

[Free flaps use in chronic wounds: Retrospective study about 91 cases].

Introduction: Chronic wounds represent a major health challenge with no current standardized surgical treatment. The use of free flaps is little discussed in the literature, with a supposed propensity to failure given unfavorable local conditions and land often debility. We present here the analysis of our monocentric experience of the use of free flaps in the curative treatment of chronic wounds.

Induced Pluripotent Stem Cells for Primary Ciliary Dyskinesia Modeling and Personalized Medicine.

Primary ciliary dyskinesia (PCD) is a rare and heterogeneous genetic disorder that affects the structure and function of motile cilia. In the airway epithelium, impaired ciliary motion results in reduced or absent mucociliary clearance that leads to the appearance of chronic airway infection, sinusitis, and bronchiectasis. Currently, there is no effective treatment for PCD, and research is limited by the lack of convenient models to study this disease and investigate innovative therapies.

Haplotypes Are Differentially Associated with Asthmatic Features.

Human leukocyte antigen (HLA)-G, a HLA class Ib molecule, interacts with receptors on lymphocytes such as T cells, B cells, and natural killer cells to influence immune responses. Unlike classical HLA molecules, HLA-G expression is not found on all somatic cells, but restricted to tissue sites, including human bronchial epithelium cells (HBEC). Individual variation in HLA-G expression is linked to its genetic polymorphism and has been associated with many pathological situations such as asthma, which is characterized by epithelium abnormalities and inflammatory cell activation.

Concise Review: Assessing the Genome Integrity of Human Induced Pluripotent Stem Cells: What Quality Control Metrics?

Human induced pluripotent stem cells (hiPSCs) have the potential to differentiate virtually into any cell type in unlimited quantities. Therefore, they are ideal for in vitro tissue modeling or to produce cells for clinical use. Importantly, and differently from immortalized and cancer cell lines, the hiPSC genome scrupulously reproduces that of the cell from which they were derived.

Epidermal Growth Factor Represses Constitutive Androstane Receptor Expression in Primary Human Hepatocytes and Favors Regulation by Pregnane X Receptor.

Growth factors have key roles in liver physiology and pathology, particularly by promoting cell proliferation and growth. Recently, it has been shown that in mouse hepatocytes, epidermal growth factor receptor (EGFR) plays a crucial role in the activation of the xenosensor constitutive androstane receptor (CAR) by the antiepileptic drug phenobarbital. Due to the species selectivity of CAR signaling, here we investigated epidermal growth factor (EGF) role in CAR signaling in primary human hepatocytes.

Lung development, regeneration and plasticity: From disease physiopathology to drug design using induced pluripotent stem cells.

Lungs have a complex structure composed of different cell types that form approximately 17 million airway branches of gas-delivering bronchioles connected to 500 million gas-exchanging alveoli. Airways and alveoli are lined by epithelial cells that display a low rate of turnover at steady-state, but can regenerate the epithelium in response to injuries. Here, we review the key points of lung development, homeostasis and epithelial cell plasticity in response to injury and disease, because this knowledge is required to develop new lung disease treatments.

Polymorphisms Associated with Rheumatoid Arthritis Susceptibility in Tunisian and French Female Populations: Influence of Geographic Origin.

Polymorphisms have been identified in the Xq28 locus as risk loci for rheumatoid arthritis (RA). Here, we investigated the association between three polymorphisms in the Xq28 region containing and (rs13397, rs1059703, and rs1059702) in two unstudied populations: Tunisian and French. The rs13397 G and rs1059703 T major alleles were significantly increased in RA patients ( = 408) compared with age-matched controls ( = 471) in both Tunisian and French women.

Laparoscopic surgery for pancreatic neoplasms: the European association for endoscopic surgery clinical consensus conference.

Background: Introduced more than 20 years ago, laparoscopic pancreatic surgery (LAPS) has not reached a uniform acceptance among HPB surgeons. As a result, there is no consensus regarding its use in patients with pancreatic neoplasms. This study, organized by the European Association for Endoscopic Surgery (EAES), aimed to develop consensus statements and clinical recommendations on the application of LAPS in these patients.

Tuning a cellular lipid kinase activity adapts hepatitis C virus to replication in cell culture.

With a single exception, all isolates of hepatitis C virus (HCV) require adaptive mutations to replicate efficiently in cell culture. Here, we show that a major class of adaptive mutations regulates the activity of a cellular lipid kinase, phosphatidylinositol 4-kinase IIIα (PI4KA). HCV needs to stimulate PI4KA to create a permissive phosphatidylinositol 4-phosphate-enriched membrane microenvironment in the liver and in primary human hepatocytes (PHHs).
