Multiple-dose versus single-dose ivermectin for Strongyloides stercoralis infection (Strong Treat 1 to 4): a multicentre, open-label, phase 3, randomised controlled superiority trial.

Background: Strongyloides stercoralis infection is a neglected condition that places people who are immunocompromised at risk of hyperinfection and death. Ivermectin is the drug of choice for the treatment of S stercoralis infection, but there is no definitive evidence on the optimal dose. This trial aimed to assess whether multiple doses of ivermectin were superior to a single dose for the treatment of non-disseminated strongyloidiasis.

Formal calculation of exchange correlation effects on annihilation lifetimes of positronium confined in small cavities.

Positronium atoms (Ps) are widely used as a probe to characterize voids or vacancies in non-metallic materials. The annihilation lifetime of trapped Ps is strongly modified by pickoff, depending on the cavity size and on the appropriate external electron density. The connection between these material characteristics and Ps annihilation lifetimes is usually based on models that do not consider the requirements of full electron indistinguishability, that must be taken into account for a correct description of pickoff annihilation processes.

Italian recommendations for influenza and pneumococcal vaccination in adult patients with autoimmune rheumatic diseases.

Objectives: To provide evidence-based recommendations for vaccination against influenza virus and S. pneumoniae in patients with autoimmune rheumatic diseases (ARDs).

Methods: A Consensus Committee including physicians with expertise in rheumatic and infectious diseases was established by two Italian scientific societies, Società Italiana di Reumatologia (SIR) and Società Italiana di Malattie Infettive e Tropicali (SIMIT).

Non-typhoidal Salmonella aortitis.

Non-typhoidal Salmonella (NTS) spp. causes about 40% of all infective aortitis and it is characterized by high morbidity and mortality. Human infection occurs by fecal-oral transmission through ingestion of contaminated food, milk, or water (inter-human or zoonotic transmission).

Disengagement and reengagement of HIV continuum of care in a single center cohort in northern Italy.

Despite the progress in HIV care, adherence to follow up remains critical. Disengagement impairs the benefit of HIV care and the increasing number of data that associates failed retention with worse outcomes has led public health institutions to consider retention in care as a new tool to fight against HIV pandemic. The aim of this retrospective, observational study was to estimate the burden of disengagement and reengagement in care in our HIV cohort and to identify the characteristics of our LTFU and reengaged patients.

Very high pre-therapy viral load is a predictor of virological rebound in HIV-1-infected patients starting a modern first-line regimen.

Background: Pre-cART (combined antiretroviral therapy) plasma viral load >500,000 copies/ml has been associated with a lower probability of achieving virological suppression, while few data about its role on maintenance of virological suppression are available. In this study we aimed to clarify whether high levels of pre-cART viraemia are associated with virological rebound (VR) after virological suppression.

Methods: HIV-infected individuals who achieved virological suppression after first-line cART were included.

Infectious diseases at different stages of migration: an expert review.

Background: Human migration is increasing in magnitude and scope. The majority of migrants arriving in high-income countries originate from countries with a high prevalence of infectious diseases. The risk and burden of infectious diseases are not equally distributed among migrant groups and vary with migration stage.

Migration Medicine.

Migration is increasing and practitioners need to be aware of the unique health needs of this population. The prevalence of infectious diseases among migrants varies and generally mirrors that of their countries of origin, but is modified by the circumstance of migration, the presence of pre-arrival screening programs and post arrival access to health care. To optimize the health of migrants practitioners; (1) should take all opportunities to screen migrants at risk for latent infections such as tuberculosis, chronic hepatitis B and C, HIV, strongyloidiasis, schistosomiasis and Chagas disease, (2) update routine vaccines in all age groups and, (3) be aware of "rare and tropical infections" related to migration and return travel.

The diagnosis and treatment of urogenital schistosomiasis in Italy in a retrospective cohort of immigrants from Sub-Saharan Africa.

Objectives: To evaluate ultrasound and praziquantel to, respectively, assess and reduce urogenital schistosomiasis (UGS)-associated morbidity in migrants from Sub-Saharan Africa (SSA).

Methods: Migrants from SSA with UGS attending three Italian centres for tropical diseases during 2011-2016 were retrospectively enrolled. Data on clinical symptoms, routine laboratory, parasitological tests, and ultrasound reported as per the WHO-Niamey protocol were collected at baseline and at available follow-up visits after treatment with praziquantel 40 mg/kg/day for 3 days.

Anthropomorphizing without Social Cues Requires the Basolateral Amygdala.

Anthropomorphism, the attribution of distinctively human mental characteristics to nonhuman animals and objects, illustrates the human propensity for extending social cognition beyond typical social targets. Yet, its processing components remain challenging to study because they are typically all engaged simultaneously. Across one pilot study and one focal study, we tested three rare people with basolateral amygdala lesions to dissociate two specific processing components: those triggered by attention to social cues (e.

Differential Scanning Calorimetry Analyses of Idebenone-Loaded Solid Lipid Nanoparticles Interactions with a Model of Bio-Membrane: A Comparison with In Vitro Skin Permeation Data.

Differential scanning calorimetry (DSC) has emerged as a helpful technique both to characterize drug delivery systems and to study their interactions with bio-membranes. In this work, we compared idebenone (IDE)-loaded solid lipid nanoparticle (SLN) interactions with bio-membranes assessed by DSC with previous in vitro skin penetration data to evaluate the feasibility of predicting IDE skin penetration using DSC analyses. In vitro interactions experiments were performed using multi-lamellar liposomes as a model of bio-membrane.

Effectiveness and safety of switching to entecavir hepatitis B patients developing kidney dysfunction during tenofovir.

Background And Aims: Tenofovir disoproxil fumarate (TDF) is recommended for chronic hepatitis B (CHB) treatment, but it may induce kidney dysfunction whose management is not yet known. This Italian, multicentre, retrospective study aimed to assess the efficacy and safety of switching to entecavir (ETV) patients who developed TDF-associated glomerular and/or tubular dysfunction.

Methods: A total of 103 TDF-treated patients were included as follows: age 64 years, 83% male, 49% cirrhotics, 98% with undetectable HBV DNA, 47% with previous lamivudine resistance (LMV-R) and 71% previously treated with adefovir.

A COPD Case-Finding Program in a Large Cohort of HIV-Infected Persons.

Background: COPD screening guidelines in patients with HIV are lacking, and data about its under-diagnosis are still limited. This study aimed to determinate the feasibility of a case-finding program and the prevalence of COPD under-diagnosis in a large cohort of HIV-infected subjects.

Methods: All out-patients attending their routine visit for HIV monitoring at Spedali Civili General Hospital in Brescia, Italy, from February 2015 to January 2016, were enrolled.

Anomalous interaction of tri-acyl ester derivatives of uridine nucleoside with a l-α-dimyristoylphosphatidylcholine biomembrane model: a differential scanning calorimetry study.

Objectives: Uridine was conjugated with fatty acids to improve the drug lipophilicity and the interaction with phospholipid bilayers.

Methods: The esterification reaction using carbodiimides compounds as coupling agents and a nucleophilic catalyst allowed us to synthesize tri-acyl ester derivatives of uridine with fatty acids. Analysis of molecular interactions between these tri-acyl ester derivatives and l-α-dimyristoylphosphatidylcholine (DMPC) multilamellar vesicles (MLV) - as a mammalian cell membrane model - have been performed by differential scanning calorimetry (DSC).

Dolutegravir-rilpivirine: first 2-drug regimen for HIV-positive adults.

New strategies for HIV treatment are being investigated to reduce drug-exposure, toxicities, and costs. Dolutegravir (DTG) 50 mg/rilpivirine (RPV) 25 mg was approved in November 2017 by FDA and in May 2018 by the European Medicines Agency (EMA). It is indicated as a complete regimen for HIV-1 infected adults with undetectable plasmatic HIV-RNA for at least 6 months on their current HIV treatment combination.

Immune components of early breastmilk: Association with maternal factors and with reported food allergy in childhood.

Background: Breastmilk (BM) may participate in driving gut barrier function and immunity in the neonate. We analyzed immune and growth factor concentrations in early BM and their association with maternal/environmental characteristics and with food allergy (FA) in childhood.

Methods: One BM sample was collected in maternity from some mothers in the EDEN birth cohort (n = 2002 mother-child dyads).

Screening for active and latent tuberculosis among asylum seekers in Italy: A retrospective cohort analysis.

Background: The World Health Organization conditionally recommends systematic screening of tuberculosis (TB) and Latent Tuberculosis Infection (LTBI) among asylum seekers (AS) from high-burden countries, but the effectiveness of different screening approaches is controversial.

Methods: We report the results of a retrospective cohort analysis of TB and LTBI screening among consecutive AS in Brescia, Italy during 2015-2016. TB screening was based on symptoms, LTBI screening on the tuberculin skin test (TST).

A Novel Subfamily of Bacterial AAT-Fold Basic Amino Acid Decarboxylases and Functional Characterization of Its First Representative: Pseudomonas aeruginosa LdcA.

Polyamines are small amino-acid derived polycations capable of binding negatively charged macromolecules. Bacterial polyamines are structurally and functionally diverse, and are mainly produced biosynthetically by pyridoxal-5-phosphate-dependent amino acid decarboxylases referred to as Lysine-Arginine-Ornithine decarboxylases (LAOdcs). In a phylogenetically limited group of bacteria, LAOdcs are also induced in response to acid stress.
