Comprehensive genomic profiling by liquid biopsy captures tumor heterogeneity and identifies cancer vulnerabilities in patients with RAS/BRAF wild-type metastatic colorectal cancer in the CAPRI 2-GOIM trial.

Background: Emerging evidence supports tumor tissue-based comprehensive genomic profiling (CGP) in metastatic colorectal cancer (mCRC). Data on liquid biopsy-based circulating tumor DNA (ctDNA) CGP are scarce and mainly retrospective. Prospective comparison between the two tests is not currently available.

Resistance to immune checkpoint inhibitors in colorectal cancer with deficient mismatch repair/microsatellite instability: misdiagnosis, pseudoprogression and/or tumor heterogeneity?

Colorectal carcinoma (CRC) with deficiency of the deficient mismatch repair (dMMR) pathway/microsatellite instability (MSI) is characterized by a high mutation load and infiltration of immune cells in the tumor microenvironment. In agreement with these findings, clinical trials have demonstrated a significant activity of immune checkpoint inhibitors (ICIs) in dMMR/MSI metastatic CRC (mCRC) patients and, more recently, in CRC patients with early disease undergoing neoadjuvant therapy. However, despite high response rates and durable clinical benefits, a fraction of mCRC patients, up to 30%, showed progressive disease when treated with single agent anti-programmed cell death 1 (PD-1) antibody.

Advances in the understanding of the pathophysiology of schizophrenia and bipolar disorder through induced pluripotent stem cell models.

The pathophysiology of schizophrenia and bipolar disorder involves a complex interaction between genetic and environmental factors that begins in the early stages of neurodevelopment. Recent advancements in the field of induced pluripotent stem cells (iPSCs) offer a promising tool for understanding the neurobiological alterations involved in these disorders and, potentially, for developing new treatment options. In this review, we summarize the results of iPSC-based research on schizophrenia and bipolar disorder, showing disturbances in neurodevelopmental processes, imbalance in glutamatergic-GABAergic transmission and neuromorphological alterations.

The role of anti-EGFR therapies in EGFR-TKI-resistant advanced non-small cell lung cancer.

Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are the current recommended option for the first-line treatment of patients with EGFR-mutant non-small cell lung cancer (NSCLC). Resistance to first-generation TKIs led to the development of second- and third-generation TKIs with improved clinical outcomes. However, sequential administration of TKIs has led to the emergence of new EGFR resistance mutations and persistent tumor cell survival.

Evidence of an anti-inflammatory effect of PCSK9 inhibitors within the human atherosclerotic plaque.

Background And Aims: Preclinical evidence suggests that proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors hold anti-inflammatory properties independently of their ability to lower LDL-cholesterol (C). However, whether PCSK9 inhibitors exert anti-inflammatory effects within the atherosclerotic plaque in humans is unknown. We explored the impact of PCSK9 inhibitors, used as monotherapy, compared with other lipid-lowering drugs (oLLD) on the expression of inflammatory markers within the plaque, assessing also the subsequent incidence of cardiovascular events.

The cloud of unknowing: Cognitive dedifferentiation in whole-body perceptual deprivation.

An altered sensory environment, especially a homogeneous one like a ganzfeld, can induce a wide range of experiences in people immersed in it. The ganzfeld of our current focus is the OVO Whole-Body Perceptual Deprivation chamber (OVO-WBPD). Previous literature has found this specific immersive environment to be capable of softening and dissolving perception of boundaries across time and sensory modalities, among other domains.

Bivalent second booster dose of the COVID-19 vaccine: Eligible populations' reasons for receiving in Italy.

The Italian Ministry of Health recommended the administration of the bivalent second booster dose of the new available mRNA COVID-19 vaccine for subjects aged 60 y and over, aged 12 y and over with high frailty motivated by concomitant/preexisting conditions, and health-care workers. The purposes of this cross-sectional survey were to investigate the reasons for receiving the bivalent second booster dose of the COVID-19 vaccine and associated influencing factors among the eligible population attending two immunization centers randomly selected in the city of Naples, Italy. A total of 535 subjects participated.

Midwives' Knowledge, Attitudes, and Practice Regarding COVID-19 Vaccination for Pregnant Women: A Nationwide Web-Based Survey in Italy.

This cross-sectional survey investigated the knowledge, attitudes, and practices concerning the COVID-19 vaccination for pregnant women among midwives in Italy and the associated factors. Midwives with at least five years of midwifery education and who had received information about the COVID-19 vaccination from official government organizations or scientific journals were more likely to know in which trimester this vaccine can be administered. A higher perceived utility of this vaccination was observed among midwives working in the public sector, in those concerned by being infected by SARS-CoV-2, who have received at least one dose of this vaccination, in those who considered COVID-19 a severe disease for pregnant women and their fetus, and who believed that the vaccination is safe.

Introduction: We present the results of a phase 2a trial of first-line avelumab (anti-programmed death-ligand 1 antibody) plus cetuximab (anti-EGFR antibody) in patients with advanced squamous NSCLC.

Methods: Patients with recurrent or metastatic squamous NSCLC received avelumab 800 mg (d 1 and 8), cetuximab 250 mg/m (d 1) and 500 mg/m (d 8), cisplatin 75 mg/m (d 1), and gemcitabine 1250 mg/m (d 1 and 8) for four 3-week cycles, followed by avelumab 800 mg and cetuximab 500 mg/m every 2 weeks. The primary end point was the best overall response; the secondary end points were progression-free survival, duration of response, overall survival, and safety.

SIRT3 mediates the effects of PCSK9 inhibitors on inflammation, autophagy, and oxidative stress in endothelial cells.

: Proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors (i) are a class of lipid-lowering drugs suggested to hold a plethora of beneficial effects independent of their LDL cholesterol-lowering properties. However, the mechanism underlying such observations is debated. : Human aortic endothelial cells (TeloHAEC) were pre-treated with 100 µg/mL of the PCSK9i evolocumab and then exposed to 20 ng/mL of IL-6, a major driver of cardiovascular diseases (CVD), in both naïve state and after siRNA-mediated suppression of the NAD-dependent deacetylase sirtuin-3 (SIRT3).

COVID-19 Vaccination among a Population Experiencing Homelessness: A Survey in Italy.

The purposes of this cross-sectional study were to determine the knowledge, attitudes, and behaviors about COVID-19 and its vaccination among 313 individuals experiencing homelessness in Italy and to identify the associated factors. A total of 20.5% identified the virus as a causative agent for COVID-19 and 44.

Hyperuricemia and Endothelial Function: Is It a Simple Association or Do Gender Differences Play a Role in This Binomial?

The endothelium plays a fundamental role in the biological processes that ensure physiological vessel integrity, synthesizing numerous substances that are capable of modulating the tone of vessels, inflammation and the immune system, and platelet function. Endothelial dysfunction refers to an anomaly that develops at the level of the tunica that lines the internal surface of arterial and venous vessels, or, more precisely, an alteration to normal endothelial function, which involves the loss of some structural and/or functional characteristics. Studies on sex differences in endothelial function are conflicting, with some showing an earlier decline in endothelial function in men compared to women, while others show a similar age of onset between the sexes.

Parents' reasons to vaccinate their children aged 5-11 years against COVID-19 in Italy.

Objectives: The aims of this cross-sectional study were to investigate why parents decide to vaccinate, as well as the determinants, their children aged 5-11 years against COVID-19 in Italy.

Methods: The survey was conducted from January through May 2022. All parents/guardians who came in randomly selected days to immunization centers for the administration of the first dose of the COVID-19 vaccine to their child were asked to complete a questionnaire about socio-demographic characteristics, attitudes toward COVID-19 infection and vaccination, reason(s) regarding their decision to vaccinate their child, and source(s) of information.

Glycated ACE2 reduces anti-remodeling effects of renin-angiotensin system inhibition in human diabetic hearts.

Background: High glycated-hemoglobin (HbA1c) levels correlated with an elevated risk of adverse cardiovascular outcomes despite renin-angiotensin system (RAS) inhibition in type-2 diabetic (T2DM) patients with reduced ejection fraction. Using the routine biopsies of non-T2DM heart transplanted (HTX) in T2DM recipients, we evaluated whether the diabetic milieu modulates glycosylated ACE2 (GlycACE2) levels in cardiomyocytes, known to be affected by non-enzymatic glycosylation, and the relationship with glycemic control.

Objectives: We investigated the possible effects of GlycACE2 on the anti-remodeling pathways of the RAS inhibitors by evaluating the levels of Angiotensin (Ang) 1-9, Ang 1-7, and Mas receptor (MasR), Nuclear-factor of activated T-cells (NFAT), and fibrosis in human hearts.
