Long-term outcome following liver transplantation of patients with ACLF grade 3.

Background & Aims: Utility, a major principle for allocation in the context of transplantation, is questioned in patients with acute-on-chronic liver failure grade 3 (ACLF-3) who undergo liver transplantation (LT). We aimed to explore long-term outcomes of patients included in a three-centre retrospective French study published in 2017.

Method: All patients with ACLF-3 (n = 73), as well as their transplanted matched controls with ACLF-2 (n = 145), 1 (n = 119) and no ACLF (n = 292), who participated in the Princeps study published in 2017 were included.

Screening for hepatitis C virus at the time of mammography using rapid diagnostic tests in women aged between 50 and 74 years (Mamm'OC NCT05067374).

Chronic hepatitis C Virus (HCV) infection presents a global health challenge, with significant morbidity and mortality worldwide. Despite remarkable progress in treatment options, achieving elimination targets by 2030, as set by the World Health Organization, remains elusive. Our study aimed to address this gap by integrating HCV screening into a national breast cancer screening program.

Abdominal surgery in patients with chronic noncirrhotic extrahepatic portal vein obstruction: A multicenter retrospective study.

Background And Aims: In patients with noncirrhotic chronic extrahepatic portal vein obstruction (EHPVO), data on the morbimortality of abdominal surgery are scarce.

Approach And Results: We retrospectively analyzed the charts of 76 patients (78 interventions) with EHPVO undergoing abdominal surgery within the Vascular Disease Interest Group network. Fourteen percent of the patients had ≥1 major bleeding (unrelated to portal hypertension) and 21% had ≥1 Dindo-Clavien grade ≥3 postoperative complications within 1 month after surgery.

The role and evolution of partial splenic embolization over three decades: A multicentric retrospective single cohort study of 90 patients from French nationwide experience.

Background: Partial splenic embolization (PSE) has been proposed to treat the consequences of hypersplenism in the context of portal hypertension, especially thrombocytopenia. However, a high morbidity/mortality rate has made this technique unpopular. We conducted a multicenter retrospective nationwide French study to reevaluate efficacy and tolerance.

Adaptative Strategy of Immunosuppressive Drugs Dosage Adjustments When Combined With Nirmatrelvir/Ritonavir in Solid Organ Transplant Recipients With COVID-19.

Nirmatrelvir/ritonavir is a promising option for preventing severe COVID-19 in solid organ transplant recipients with SARS-CoV-2 infection. However, concerns have arisen regarding potential drug interactions with calcineurin inhibitors (CNI). This two-phase multicentre retrospective study, involving 113 patients on tacrolimus and 13 on cyclosporine A, aimed to assess the feasibility and outcomes of recommendations issued by The French societies of transplantation (SFT) and pharmacology (SFPT) for CNI management in this context.

Targeting of M2 macrophages with IL-13-functionalized liposomal prednisolone inhibits melanoma angiogenesis .

The intricate cooperation between cancer cells and nontumor stromal cells within melanoma microenvironment (MME) enables tumor progression and metastasis. We previously demonstrated that the interplay between tumor-associated macrophages (TAMs) and melanoma cells can be disrupted by using long-circulating liposomes (LCLs) encapsulating prednisolone phosphate (PLP) (LCL-PLP) that inhibited tumor angiogenesis coordinated by TAMs. In this study, our goal was to improve LCL specificity for protumor macrophages (M2-like (i.

Lab-on-a-chip models of the blood-brain barrier: evolution, problems, perspectives.

A great progress has been made in the development and use of lab-on-a-chip devices to model and study the blood-brain barrier (BBB) in the last decade. We present the main types of BBB-on-chip models and their use for the investigation of BBB physiology, drug and nanoparticle transport, toxicology and pathology. The selection of the appropriate cell types to be integrated into BBB-on-chip devices is discussed, as this greatly impacts the physiological relevance and translatability of findings.

Formation of Precipitation Ellipsoidal Disks and Spheres in the Wake of a Planar Diffusion Front.

Pattern formation is one of the examples of self-organization. In the generation of patterns, the coupling between the mass transport of the chemical species and their chemical reactions plays an important role. Periodic precipitation (Liesegang phenomenon) is a type of pattern formation in which layered precipitation structures form in the wake of the diffusion front.

Liver disease in germline mutations of telomere-related genes: Prevalence, clinical, radiological, pathological features, outcome, and risk factors.

Background And Aim: Germline mutations of telomere-related genes (TRG) induce multiorgan dysfunction, and liver-specific manifestations have not been clearly outlined. We aimed to describe TRG mutations-associated liver diseases.

Approach And Results: Retrospective multicenter analysis of liver disease (transaminases > 30 IU/L and/or abnormal liver imaging) in patients with TRG mutations.

Nursing Training for Early Clinical Deterioration Risk Assessment: Protocol for an Implementation Study.

Background: During the hospitalization period, it is possible to observe considerable changes in the vital parameters of patients, which may require emergency interventions or intensive treatment. The alteration of signs and symptoms that lead to physiological instability that can worsen the clinical picture with progression to shock, respiratory failure, or cardiorespiratory arrest is currently defined as clinical deterioration. Identifying signs of clinical deterioration at an early stage can lead to substantial decreases in mortality rates, the need for emergency interventions, and unscheduled treatments in intensive care units.

Integrating an addiction team into the management of patients transplanted for alcohol-associated liver disease reduces the risk of severe relapse.

Background & Aims: Liver transplantation (LT) is a last resort treatment for patients at high risk of mortality from end-stage liver disease. Over the past years, alcohol-associated liver disease has become the most frequent indication for LT in the world. The outcomes of LT for alcohol-associated liver disease are good, but return to alcohol use is detrimental for medium-term survival because of cancer development, cardiovascular events, and recurrent alcohol-associated cirrhosis.

Time Spent with Saturation below 80% versus 90% in Patients with Obstructive Sleep Apnoea.

Background: Nocturnal hypoxaemia measured as the percentage of total sleep time spent with saturation below 90% (TST90%) may better predict cardiovascular consequences of obstructive sleep apnoea (OSA) than the number of obstructive respiratory events measured with the apnoea-hypopnea index (AHI). Deeper hypoxaemia may potentially induce more severe pathophysiological consequences. However, the additional value of the percentage of total sleep time spent with saturation below 80% (TST80%) to TST90% is not fully explored.

Treatment of donor-specific anti-HLA antibodies-mediated rejection after liver transplantation: A French nationwide retrospective study.

The deleterious effect of donor-specific anti-HLA antibodies (DSA) after liver transplantation (LT) has been increasingly recognized during the past decade. Antibody-mediated rejection (AMR) represents a rare but severe complication in the presence of DSA. However, little is known concerning the treatment of AMR after LT.

The link between the sphingolipid rheostat and obstructive sleep apnea.

Chronic inflammation induced by hypoxia during sleep is an important mechanism of microvascular damage in OSA patients. In this study, we investigated the role of the sphingosine rheostat, which has diverse inflammatory effects. Thirty-seven healthy subjects and 31 patients with OSA were recruited.

Effect of spring nitrogen fertilization on bearing and branching behaviors of young apple trees.

The total aboveground biomass production, nutritional status, bearing and branching behaviors of the central leader and one year old shoots of young apple trees have been analyzed. The shoots were further characterized according to the length, shoot demography, and the production of terminal and lateral flowers. All the characteristics are described in connection with nitrogen supply and cultivar.

Risk of infection in elderly patients with inflammatory bowel disease under biologics: A prospective, multicenter, observational, one-year follow-up comparative study.

Objectives: The emergence of biologics has improved the course of inflammatory bowel diseases (IBD) in the elderly population despite a potential higher risk of infections. We conducted a one-year, prospective, multicenter, observational study to determine the frequency of occurrence of at least one infectious event in elderly IBD patients under anti-TNF therapy compared with that in elderly patients under vedolizumab or ustekinumab therapies.

Methods: All IBD patients over 65 years exposed to anti-TNF, vedolizumab or ustekinumab therapies were included.

Effects of Acute Hypoxia on Heart Rate Variability in Patients with Pulmonary Vascular Disease.

Pulmonary vascular diseases (PVDs), defined as arterial or chronic thromboembolic pulmonary hypertension, are associated with autonomic cardiovascular dysregulation. Resting heart rate variability (HRV) is commonly used to assess autonomic function. Hypoxia is associated with sympathetic overactivation and patients with PVD might be particularly vulnerable to hypoxia-induced autonomic dysregulation.

Targeting Human Endothelial Cells with Glutathione and Alanine Increases the Crossing of a Polypeptide Nanocarrier through a Blood-Brain Barrier Model and Entry to Human Brain Organoids.

Nanoparticles (NPs) are the focus of research efforts that aim to develop successful drug delivery systems for the brain. Polypeptide nanocarriers are versatile platforms and combine high functionality with good biocompatibility and biodegradability. The key to the efficient brain delivery of NPs is the specific targeting of cerebral endothelial cells that form the blood-brain barrier (BBB).

Effects of Hydroxypropyl-Beta-Cyclodextrin on Cultured Brain Endothelial Cells.

The application of 2-hydroxypropyl-beta-cyclodextrin (HPBCD) in the treatment of the rare cholesterol and lipid storage disorder Niemann-Pick disease type C opened new perspectives in the development of an efficient therapy. Even if the systemic administration of HPBCD was found to be effective, its low permeability across the blood-brain barrier (BBB) limited the positive neurological effects. Nevertheless, the cellular interactions of HPBCD with brain capillary endothelial cells have not been investigated in detail.
