Levosimendan protects human hepatocytes from ischemia-reperfusion injury.
2017
Background Ischemia-reperfusion injury (IRI) is a major challenge in liver transplantation. The mitochondrial pathway plays a pivotal role in hepatic IRI. Levosimendan, a calcium channel sensitizer, was shown to attenuate apoptosis after IRI in animal livers. The aim of this study was to investigate the effect of levosimendan on apoptosis in human hepatocytes. Methods Primary human hepatocytes were either exposed to hypoxia or cultured under normoxic conditions. After the hypoxic phase, reoxygenation was implemented and cells were treated with different concentrations of levosimendan (10ng/ml, 100ng/ml, 1000ng/ml). The overall metabolic activity of the cells was measured using 3-(4,5-dimeth…
Hepatoceliac Lymph Node Involvement in Advanced Ovarian Cancer Patients: Prognostic Role and Clinical Considerations.
2017
Background: The study aimed too investigate the rate of hepatoceliac lymph node (HCLN) involvement, as well as its association with clinicopathologic features, together with morbidity of HCLN resection and the prognostic impact of metastatic HCLN status on patients with advanced ovarian cancer (OC) undergoing cytoreductive surgery. Methods: All consecutive patients with stages 3c to 4 epithelial OC who underwent HCLN surgery from January 2010 to September 2016 were analyzed for surgical procedures, pathology, and oncologic outcomes. Results: During the study period, 85 patients underwent HCLN resection. Absence of visible tumor at the end of surgery was documented for 73 of the patients (85…
M-TRAP: Safety and performance of metastatic tumor cell trap device in advanced ovarian cancer patients
2021
Objective. Despite radical surgery and chemotherapy, most patients with ovarian cancer die due to disease progression. M-Trap is an implantable medical device designed to capture peritoneal disseminated tumor cells with the aim to focalize the disease. This trial analyzed the safety and performance of the device. Methods. This first-in-human prospective, multi-center, non-blinded, single-arm study enrolled 23 women with high-grade serous advanced ovarian cancer. After primary or interval debulking surgery, 3 M-Trap devices were placed in the peritoneum of the abdominal cavity. 18-months post-implantation or at disease progression, devices were initially removed by laparoscopy. The primary s…
Neoadjuvant eribulin mesylate following anthracycline and taxane in triple negative breast cancer: Results from the HOPE study
2019
BackgroundEribulin mesylate (E) is indicated for metastatic breast cancer patients previously treated with anthracycline and taxane. We argued that E could also benefit patients eligible for neoadjuvant chemotherapy.MethodsPatients with primary triple negative breast cancer ≥2 cm received doxorubicin 60 mg/m2 and paclitaxel 200 mg/m2 x 4 cycles (AT) followed by E 1.4 mg/m2 x 4 cycles. Primary endpoint was pathological complete response (pCR) rate; secondary and explorative endpoints included clinical/metabolic response rates and safety, and biomarker analysis, respectively. Using a two-stage Simon design, 43 patients were to be included provided that 4 of 13 patients had achieved pCR in the…
Impact of Donor Activating KIR Genes on HSCT Outcome in C1-Ligand Negative Myeloid Disease Patients Transplanted with Unrelated Donors-A Retrospectiv…
2017
Natural Killer cells (NK) are lymphocytes with the potential to recognize and lyse cells which escaped T-cell mediated lysis due to their aberrant HLA expression profiles. Killer cell immunoglobulin-like receptors (KIR) influence NK-cell activity by mediation of activating or inhibitory signals upon interaction with HLA-C (C1, C2) ligands. Therefore, absence of ligands for donor inhibitory KIRs following hematopoietic stem cell transplantation (HSCT) may have an influence on its outcome. Previous studies showed that C1 negative patients have a decreased HSCT outcome. Our study, based on a cohort of 200 C1-negative patients, confirmed these findings for the endpoints: overall survival (OS: H…
Non-invasive Biomarkers of Acute Rejection in Kidney Transplantation: Novel Targets and Strategies
2019
Abstract: Kidney transplantation is considered the favored treatment for patients suffering from end-stage renal disease, since successful transplantation is associated with longer survival and improved quality of life compared to dialysis. Alloreactive immune responses against the donor kidney may lead to acute rejection of the transplant. The current diagnosis of renal allograft rejection mainly relies on clinical monitoring, including serum creatinine, proteinuria, and confirmation by histopathologic assessment in the kidney transplant biopsy. These parameters have their limitations. Identification and validation of biomarkers, which correlate with or predict the presence of acute reject…
Population pharmacokinetic meta-analysis of individual data to design the first randomized efficacy trial of vancomycin in neonates and young infants.
2019
Abstract Objectives In the absence of consensus, the present meta-analysis was performed to determine an optimal dosing regimen of vancomycin for neonates. Methods A ‘meta-model’ with 4894 concentrations from 1631 neonates was built using NONMEM, and Monte Carlo simulations were performed to design an optimal intermittent infusion, aiming to reach a target AUC0–24 of 400 mg·h/L at steady-state in at least 80% of neonates. Results A two-compartment model best fitted the data. Current weight, postmenstrual age (PMA) and serum creatinine were the significant covariates for CL. After model validation, simulations showed that a loading dose (25 mg/kg) and a maintenance dose (15 mg/kg q12h if <…
A conditional inducible JAK2V617F transgenic mouse model reveals myeloproliferative disease that is reversible upon switching off transgene expressio…
2019
Aberrant activation of the JAK/STAT pathway is thought to be the critical event in the pathogenesis of the chronic myeloproliferative neoplasms, polycythemia vera, essential thrombocythemia and primary myelofibrosis. The most frequent genetic alteration in these pathologies is the activating JAK2V617F mutation, and expression of the mutant gene in mouse models was shown to cause a phenotype resembling the human diseases. Given the body of genetic evidence, it has come as a sobering finding that JAK inhibitor therapy only modestly suppresses the JAK2V617F allele burden, despite showing clear benefits in terms of reducing splenomegaly and constitutional symptoms in patients. To gain a better …
The morphogenetically active polymer, inorganic polyphosphate complexed with GdCl 3 , as an inducer of hydroxyapatite formation in vitro
2015
Inorganic polyphosphate (polyP) is a physiological polymer composed of tens to hundreds of phosphate units linked together via phosphoanhydride bonds. Here we compared the biological activity of polyP (chain length of 40 phosphate units), complexed with Gd(3+) (polyP·Gd), with the one caused by polyP (as calcium salt) and by GdCl3 alone, regarding their potencies to induce hydroxyapatite (HA) formation in SaOS-2 cells in vitro. The three compounds, GdCl3, polyP and polyP·Gd were found to be non-toxic at concentrations up to at least 30μM. Selecting a low, 5μM, concentration it was found that polyP·Gd significantly induced HA formation, as determined by Alizarin Red S staining and by quantit…
Physical fitness assessment in Goalball: A scoping review of the literature
2020
Background Goalball is a Paralympic sport for visually impaired athletes. Although it is widely practiced, a great variety of tests are adopted to evaluate athletes' physical fitness. Therefore, the objective was to identify the physical fitness tests adopted in this sport to find the common aspects between them and, eventually, to propose a standard operating procedure. Methods The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines were adopted. The studies were extracted from PubMed, Web of Science, and Scopus. A selection process by title, abstract, and full-text, according to the inclusion and exclusion criteria, was …
