Mechanical stresses numerical simulations had shown different corneal behaviours in term of shape deformity, apical raise and corneal applanation between healthy and KC stages models. Apical rise ranged from 0.122 to 0.389 mm for an applied intraocular pressure that equals to 15 mmHg. A normal stress of 5 kPa provoked a corneal applanation that ranged from 0.27 mm in healthy cases to 1.173 mm in severe stages of the disease. The application of 2.5 kPa biaxial stress had resulted normal and tangential applanations that successively ranged from 0.152 and 0.173 mm in healthy corneas to 0.446 mm and 0.458 mm in severe KC stages. An adopted prognosis algorithm was able to predict the current stage of the disease and to estimate the remaining number of eye rubbing cycles before failure. CONCLUSION Eye rubbing was proven to be a considerable contributing factor in KC patient's corneal degeneration. The progression of this pathology could be decreased or halted by stopping eye rubbing at early stages.Speckle tracking echocardiography (STE) is a second-level echocardiographic technique which has gradually gained relevance in the last years. It allows semi-automatic quantification of myocardial deformation and function, overcoming most of the limitations characterizing basic echocardiography and providing an early detection of cardiac impairment. Today, its feasibility and usefulness are highly supported by literature. In particular, several studies demonstrated that STE could provide additional prognostic information beyond conventional echocardiographic and traditional clinical parameters. Moreover, a recent standardization of speckle tracking analysis regarding all cardiac chambers paved the way for the integration of STE in diagnostic and prognostic protocols for particular clinical settings. The aim of this review is to describe the prognostic role of STE in different clinical scenarios basing on currently available evidence.Inflammation has long been known to play a role in heart failure (HF). Earlier studies demonstrated that inflammation contributes to the pathogenesis of HF with reduced ejection fraction (HFrEF), and the knowledge about molecules and cell types specifically involved in inflammatory events has been constantly increased ever since. However, conflicting results of several trials with anti-inflammatory treatments led to the conclusions that inflammation does participate in the progression of HFrEF, but more likely it is not the primary event. Conversely, it has been suggested that inflammation drives the development of HF with preserved ejection fraction (HFpEF). Recently the pharmacological blockade of interleukin-1 has been shown to prevent HF hospitalization and mortality in patients with prior myocardial infarction, lending renewed support to the hypothesis that inflammation is a promising therapeutic target in HF. Inflammation has also been proposed to underlie both HF and commonly associated conditions, such as chronic kidney disease or cancer. Within this last paradigm, an emergent role has been ascribed to clonal hematopoiesis of indeterminate potential. Pexidartinib order Here, we summarize the recent evidence about the role of inflammation in HF, highlighting the similarities and differences in HFrEF vs. HFpEF, and discuss the diagnostic and therapeutic opportunities raised by antinflammatory-based approaches.BACKGROUND Acute kidney injury (AKI) is a frequent complication of severe acute pancreatitis (SAP). Ferroptosis is involved in a range of diseases. However, the role of ferroptosis in SAP-induced AKI has yet to be elucidated. AIMS We aimed to investigate whether ferroptosis is induced in the kidney after SAP and whether inhibition of ferroptosis ameliorates AKI in a rat model of SAP. METHODS Sodium taurocholate (5%) was retrogradely perfused into the biliopancreatic duct to establish a model of SAP with AKI in rats. The levels of serum amylase, lipase, tumor necrosis factor (TNF)-α, interleukin (IL)-6, creatinine (Cr) and blood urea nitrogen (BUN) in rats were measured. We also determined the biochemical and morphological changes associated with ferroptosis in renal tissue, including iron accumulation, lipid peroxidation assays, and mitochondrial shrinkage. H&E staining was used to assess pancreatic and renal histological changes. Western blot analysis, RT-PCR, and immunofluorescence staining were performed to analyze the expression of ferroptosis-related proteins and genes. RESULTS SAP-induced AKI was followed by iron accumulation, increased lipid peroxidation, and upregulation of ferroptosis-related proteins and genes. Twenty-four hours after SAP, TEM confirmed the presence of typical shrunken mitochondria. Furthermore, treatment with liproxstatin-1 lowered the levels of serum amylase, TNF-α, IL-6, Cr and BUN, decreased kidney lipid peroxidation and alleviated pancreatic and renal histopathology injury in SAP rats. CONCLUSION Our findings are the first to demonstrate the involvement of ferroptosis in SAP-associated renal damage and present ferroptosis as a therapeutic target for effective treatment of SAP-induced AKI.BACKGROUND Many patients are not candidates for liver transplant for non-tumor-related reasons including medical comorbidities and non-adherence. The prognosis of patients with hepatocellular carcinoma (HCC) who are not liver transplant candidates in the era of locoregional therapy (LRT) including y90 is not well defined. AIMS This study seeks to evaluate outcomes and the natural history of early-stage HCC in patients who were denied liver transplant listing due to non-tumor reasons and instead were treated with LRT. METHODS A retrospective evaluation was performed for all patients who completed liver transplant evaluation with their tumor within Milan criteria but were denied due to non-tumor reasons and were treated with LRT at a single tertiary referral center. RESULTS The 61 patients included had a favorable overall survival, with a median survival 60.3 months (86.9% at 1 year and 52.7% at 5 years). Patients with Child-Pugh A cirrhosis (n = 34) had significantly longer overall survival compared to those with Child-Pugh B/C cirrhosis (median survival of 70.
