Clinical use of polymerase chain reaction performed on peripheral blood and bone marrow samples for the diagnosis and monitoring of visceral leishman…

2007

Background To overcome some of the limitations of conventional microbiologic techniques, polymerase chain reaction (PCR)-based assays are proposed as useful tools for the diagnosis of visceral leishmaniasis. Patients and methods A comparative study using conventional microbiologic techniques (i.e., serologic testing, microscopic examination, and culture) and a Leishmania species-specific PCR assay, using peripheral blood and bone marrow aspirate samples as templates, was conducted during an 8-year period. The study cohort consisted of 594 Italian immunocompetent (adult and pediatric) and immunocompromised (adult) patients experiencing febrile syndromes associated with hematologic alteration…

Recent acquired STD and the use of HAART in the Italian Cohort of Naive for Antiretrovirals (I.Co.N.A): analysis of the incidence of newly acquired h…

2008

Objective: To estimate the incidence of newly acquired syphilis (n-syphilis) and hepatitis B infection (n-hepatitis B) in I.Co.N.A. and to evaluate the impact of HAART, calendar date and risk group. Methods: Cohort study: Incidence was calculated by person-years analyses. Poisson regression was used for the multivariate model. Results: The rate of n-syphilis was 23.4/1,000 PYFU and it increased over time; HIV transmission risk was the most important predictor: men who have sex with men (MSM) had a considerable higher risk (RR 5.92, 95% CI 2.95-12.13 vs IDU/exIDU, p < 0.0001). The rate of n-hepatitis B was 12.2/1,000 PYFU; it declined in recent years and halved per 10 years age. Patients wit…

Producción científica, colaboración y ámbitos de investigación en Enfermedades Infecciosas y Microbiología Clínica (2003–2007)

2010

Introduction: Collaboration is essential for biomedical research. The Carlos III Health Institute (the Spanish national public organization responsible for promoting biomedical research) has encouraged scientific collaboration by promoting Thematic Networks and Cooperative Research Centres. Scientific collaboration in Enfermedades Infecciosas y Microbiologia Clinica journal is investigated. Methods: Papers published in Enfermedades Infecciosas y Microbiologia Clinica in the period 2002-2007 have been identified. Bibliometrics and Social Network Analysis methods have been carried out in order to quantify and characterise scientific collaboration and research areas. Results: A total of 805 pa…

Diagnosis of human immunodeficiency virus (HIV) infection: multicenter evaluation of a newly developed anti-HIV 1 and 2 enzyme immunoassay.

1994

A new anti-human immunodeficiency virus type 1 and 2 (anti-HIV 1 and 2) test is described. It uses recombinant p24 and peptides covering gp32, gp41, and gp120 to identify HIV-1 and HIV-2 infections. This test has been shown to be specific (99.5%) and sensitive (99.8%). In this respect, the assay was equal or superior to anti-HIV 1 and 2 tests run as references. The test was able to discriminate sera from patients with HIV infections from those from uninfected individuals with excellence; it also exerted high intra- and interassay precisions. The "modular" concept of the test allows the use of single components (gp32 or gp41) to separate between HIV-2 and HIV-1 infections, respectively.

Value of morphotyping for the characterization of Candida albicans clinical isolates

2005

Until recently, morphotyping, a method evaluating fringe and surface characteristics of streak colonies grown on malt agar, has been recommended as a simple and unexpensive typing method for Candida albicans isolates. The discriminatory power and reproducibility of Hunter's modified scheme of Phongpaichit's morphotyping has been evaluated on 28 C. albicans isolates recovered from the oral cavity of asymptomatic human immunodeficiency virus-positive subjects, and compared to two molecular typing methods: randomly amplified polymorphic DNA (RAPD) fingerprinting, and contour clamped homogeneous electric field (CHEF) electrophoretic karyotyping. Morphological features of streak colonies allowed…

Human Immunodeficiency Virus Infection and Diverse Physical Health Outcomes: An Umbrella Review of Meta-analyses of Observational Studies.

2019

Abstract Background Our aim was to assess both the credibility and strength of evidence arising from systematic reviews with meta-analyses of observational studies and physical health outcomes associated with human immunodeficiency virus (HIV) but not acquired immunodeficiency syndrome. Methods We performed an umbrella review of observational studies. Evidence was graded as convincing, highly suggestive, suggestive, weak, or nonsignificant. Results From 3413 studies returned, 20 were included, covering 55 health outcomes. Median number of participants was 18 743 (range 403–225 000 000). Overall, 45 (81.8%) of the 55 unique outcomes reported nominally significant summary results (P < .05). O…

Miti mediterranei: un viaggio millenario

2020

Ha osservato Sebastiano Tusa: «Al di là delle immense e svariate risorse materiali che il mare ha offerto ed offre all’uomo, ve ne sono altre che attengono alla sfera sovrastrutturale che hanno nei millenni rifornito ed animato l’immensa enciclopedia dei miti, delle leggende e dei culti ad esso ispirati o, comunque, connessi». Distesa senza confini e abisso insondabile, il mare, con le sue repentine mutazioni di stato, le sue furiose tempeste e le sue mortifere bonacce, si è sempre imposto a chi lo solcava per raggiungere altri luoghi o per ricavarne da vivere come spazio del pericolo e del mistero, generando e sostenendo un ampio e polimorfo immaginario e divenendo attore e scenario al con…
