TNF-alpha gene promoter polymorphisms and risk of venous thromboembolism in gastrointestinal cancer patients undergoing chemotherapy
2013
Abstract Background TNF-α has been proposed as a predictive factor for venous thromboembolism (VTE). Genetic polymorphisms could regulate TNF-α production. However, the relationship between TNFA gene variants and VTE is not clarified. This study aims to investigate the predictive role of five different TNFA gene promoter SNPs, or their haplotype combination(s), for a first VTE episode in gastrointestinal cancer out-patients treated with chemotherapy. Patients and methods Serum TNF-α levels and TNFA -863C/A, -857C/T, -376G/A, -308G/A and -238G/A gene promoter polymorphisms were retrospectively evaluated in 314 subjects, including 157 controls and 157 Caucasian patients with histologically di…
Oxidative stress in patients with Alzheimer's disease: Effect of extracts of fermented papaya powder
2015
Brain tissue is particularly susceptible to oxidative stress (OS). Increased production of reactive oxygen species (ROS), reduced antioxidant systems, and decreased efficiency in repairing mechanisms have been linked to Alzheimer’s disease (AD). Postmortem studies in AD patients’ brains have shown oxidative damage markers (i.e., lipid peroxidation, protein oxidative damage, and glycoxidation). Fermented papaya (FPP, a product ofCarica papaya Linnfermentation with yeast) is a nutraceutical supplement with favorable effects on immunological, hematological, inflammatory, and OS parameters in chronic/degenerative diseases. We studied 40 patients (age 78.2 ± 1.1 years), 28 AD patients, and 12 co…
Janus -faced liposomes enhance antimicrobial innate immune response in Mycobacterium tuberculosis infection
2012
We have generated unique asymmetric liposomes with phosphatidylserine (PS) distributed at the outer membrane surface to resemble apoptotic bodies and phosphatidic acid (PA) at the inner layer as a strategy to enhance innate antimycobacterial activity in phagocytes while limiting the inflammatory response. Results show that these apoptotic body-like liposomes carrying PA (ABL/PA) ( i ) are more efficiently internalized by human macrophages than by nonprofessional phagocytes, ( ii ) induce cytosolic Ca 2+ influx, ( iii ) promote Ca 2+ -dependent maturation of phagolysosomes containing Mycobacterium tuberculosis (MTB), ( iv ) induce Ca 2+ -dependent reactive oxygen species (ROS) production, (…
Comments on "Real-world re-treatment outcomes of direct-acting antiviral therapy failure in patients with chronic hepatitis C".
2022
Dear Editor, Elhence et al.1 assessed the retreatment outcomes of direct‐ acting antivirals (DAAs) therapy failure in a cohort of 40 patients with chronic hepatitis C (HCV) and previous virological failure (VF) to DAAs. The results were remarkable, with an overall sustained virologic response (SVR) of 100% in patients who completed retreatment with sofosbuvir and velpatasvir (with/without ribavirin). We compared these results with our experience in the multicenter HCV‐ Surveillance Cohort Long‐Term Toxicity Antivirals (HCV‐SCOLTA) cohort, an active pharmacovigilance system supported by the CISAI group (Italian Coordinators for the Study of Allergies and HIV Infection). Since 2012, Italian i…
Apoe genotypes and brain imaging classes in normal cognition, mild cognitive impairment, and alzheimer’s disease: A longitudinal study
2020
Objective: To evaluate in 419 stroke-free cognitively normal subjects (CN) aged 45-82 years covering during a long prospective study (11.54 ± 1.47 years) the preclinical to dementia spectrum: 1) the distribution of small vessel disease (V) and brain atrophy (A) aggregated as following: V−/A−, V−/A+, V+/A−, V+/A+; 2) the relationship of these imaging classes with individual apolipoprotein E (APOE) genotypes; 3) the risk of progression to Alzheimer Disease (AD) of the individual APOE genotypes. Methods: Participants underwent one baseline (t0), and 4 clinical and neuropsychological assessments (t1,t2,t3, and t4). Brain MRI was performed in all subjects at t0, t2, t3 and t4.. White matter hyp…
Genetic discontinuity between local hunter-gatherers and central Europe's first farmers.
2009
Cultivating Farmers Were the ancestors of modern Europeans the local hunter-gatherers who assimilated farming practices from neighboring cultures, or were they farmers who migrated from the Near East in the early Neolithic? By analyzing ancient hunter-gatherer skeletal DNA from 2300 to 13,400 B.C.E. Bramanti et al. (p. 137 , published online 3 September) investigated the genetic relationship of European Ice Age hunter-gatherers, the first farmers of Europe, and modern Europeans. The results reject the hypothesis of direct continuity between hunter-gatherers and early farmers and between hunter-gatherers and modern Europeans. Major parts of central and northern Europe were colonized by incom…

Guideline on management of the acute asthma attack in children by Italian Society of Pediatrics
2018
Abstract Background Acute asthma attack is a frequent condition in children. It is one of the most common reasons for emergency department (ED) visit and hospitalization. Appropriate care is fundamental, considering both the high prevalence of asthma in children, and its life-threatening risks. Italian Society of Pediatrics recently issued a guideline on the management of acute asthma attack in children over age 2, in ambulatory and emergency department settings. Methods The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology was adopted. A literature search was performed using the Cochrane Library and Medline/PubMed databases, retrieving studies in Englis…

Molecular epidemiology and whole genome sequencing analysis of clinical Mycobacterium bovis from Ghana
2019
[Background]: Bovine tuberculosis (bTB) caused by Mycobacterium bovis is a re-emerging problem in both livestock and humans. The association of some M. bovis strains with hyper-virulence, MDR-TB and disseminated disease makes it imperative to understand the biology of the pathogen.
