Immune checkpoint inhibitors (ICI) have become a key component of therapy for several solid tumours. In patients diagnosed with advanced clear cell renal cell carcinoma (ccRCC), immunotherapy has always been considered as a treatment option, and anti-PD-1-based therapies are approved in both the frontline and refractory settings. Response to PD-1 blockade has been associated with numerous tumour-intrinsic and microenvironment features. Genetic characterisation of ccRCC has significantly contributed to the knowledge of tumour biology and the mechanisms of disease progression, but the interplay of genomic alterations with patterns of immune infiltration in response to PD-1 blockade remains un…

The aryl hydrocarbon receptor (AhR) in the regulation of cell–cell contact and tumor growth

2010

The aryl hydrocarbon receptor (AhR) is a ligand-dependent transcription factor, which is activated by a large group of environmental pollutants including polycyclic aromatic hydrocarbons, dioxins and planar polychlorinated biphenyls. Ligand binding leads to dimerization of the AhR with aryl hydrocarbon receptor nuclear translocator and transcriptional activation of several xenobiotic phase I and phase II metabolizing enzymes, such as cytochrome P4501A1 and glutathione- S -transferase, respectively. Since phase I enzymes convert inert carcinogens to active genotoxins, the AhR plays a key role in tumor initiation. Besides this classical route, the AhR mediates tumor promotion and recent evide…

Do not stress, just differentiate: role of stress proteins in hematopoiesis

2015

Hematopoiesis permits the constant regeneration of the blood system and is a permanent example of cell differentiation. Defects in its tight regulation can lead to either cell death or abnormal proliferation and may translate into multiple types of blood disorders, including leukemia. Heat shock proteins (HSPs), the expression of which is controlled by heat shock factors (HSFs, currently four known members),1 are a set of highly conserved proteins induced in response to a wide variety of physiological and environmental stress. HSP/HSF overexpression or mislocalization has been described in many cancers, particularly in hematology, and other diseases. Therefore, the involvement of HSFs/HSPs …

The full publication in Lancet Oncology of the Stockholm III trial helps us to understand that short-course radiotherapy in patients with localised rectal cancer could also be followed by delayed surgery.1 During more than 14 years, more than 800 patients with rectal cancer not showing unresectable features were randomised in a two-arm versus three-arm study with a non-inferiority design. Patients could be randomised to short-course radiotherapy (5×5 Gy) and immediate (within a week) versus delayed (4–8 weeks) surgery. In the three-arm randomisation patients could also be allocated to a long course of concurrent chemoradiation (25×2 Gy), with surgery performed 6–8 weeks thereafter. Time to …

Radiotherapy as single modality was considered the standard of care for low-grade gliomas, a mixed population of low proliferative tumours including oligodendrogliomas, oligoastrocytomas and grade 2 astrocytomas. However, a recently reported trial in the New England Journal of Medicine indicates1 that the addition of procarbacine, lomustine (CCNU) and vincristine, a combination known by its acronym, PCV, significantly prolongs survival in patients with low-grade glioma. When this trial was initially reported in 2012, after a median follow-up of almost 6 years, according to the estimated number of events needed to analyse the results, a significant difference in progression-free survival (PF…

From molecular mechanisms to clinical management of antineoplastic drug-induced cardiovascular toxicity: A translational overview

2019

Significance: Antineoplastic therapies have significantly improved the prognosis of oncology patients. However, these treatments can bring to a higher incidence of side-effects, including the worrying cardiovascular toxicity (CTX). Recent Advances: Substantial evidence indicates multiple mechanisms of CTX, with redox mechanisms playing a key role. Recent data singled out mitochondria as key targets for antineoplastic drug-induced CTX; understanding the underlying mechanisms is, therefore, crucial for effective cardioprotection, without compromising the efficacy of anti-cancer treatments. Critical Issues: CTX can occur within a few days or many years after treatment. Type I CTX is associated…

Hospital and outpatient models for Hematopoietic Stem Cell Transplantation: A systematic review of comparative studies for health outcomes, experienc…

2021

The number of Hematopoietic Stem Cell Transplantations has risen in the past 20 years. The practice of outpatient Hematopoietic Stem Cell Transplantation programs is increasing in an attempt to improve the quality of patient care and reduce the demand for hospital admission. A systematic review of 29 comparative studies between in-hospital and outpatient treatment of Hematopoietic Stem Cell Transplantation, with no restriction by outpatient regime was conducted. This study aims to analyse the current evidence on the effects of the outpatient model on patient-centred outcomes, comparing both in-hospital and outpatient models for autologous and allogeneic HSCT using the Triple Aim framework: …

The effects of lasers on bond strength to ceramic materials: A systematic review and meta-analysis

2018

Lasers have recently been introduced as an alternative means of conditioning dental ceramic surfaces in order to enhance their adhesive strength to cements and other materials. The present systematic review and meta-analysis aimed to review and quantitatively analyze the available literature in order to determine which bond protocols and laser types are the most effective. A search was conducted in the Pubmed, Embase and Scopus databases for papers published up to April 2017. PRISMA guidelines for systematic review and meta-analysis were followed. Fifty-two papers were eligible for inclusion in the review. Twenty-five studies were synthesized quantitatively. Lasers were found to increase bo…

Exploring hospital certification processes from the certification body’s perspective – a qualitative study

2020

Abstract Background Hospital certification is an external assessment mechanism to assure quality and safety systems. Auditors representing the certification body play a key role in certification processes, as they perform the assessment activities and interact with the involved healthcare organizations. There is limited knowledge about the approaches and methods that auditors use, such as role repertoire, conduct, and assessment practice. The purpose of this study was to explore auditors’ practice in hospital certification processes, guided by the following research questions: What styles do auditors apply in hospital certification processes, and how do auditors perceive their role in hospi…
