Antibody response to human cytomegalovirus (HCMV) glycoprotein B (gB) in AIDS patients with HCMV end-organ disease

1998

Human cytomegalovirus (HCMV)-specific antibody responses in HIV-1 infected individuals either with or without HCMV end-organ disease were examined to determine the whether development of HCMV disease was associated with a particular deficit in the antibody response. Antiwhole HCMV, anti-glycoprotein B (gB), and neutralizing antibody levels were higher in HIV-1 infected individuals than in healthy immunocompetent subjects, particularly in patients with AIDS either with or without HCMV-associated disease. Irrespective of location and spread of HCMV disease, patients who had received anti-HCMV therapy prior to sampling exhibited significantly higher anti-gB and neutralizing antibody titers tha…

A Passive-Marker-Based Optical System for Computer-Aided Surgery in Otorhinolaryngology: Development and First Clinical Experiences

1999

Objectives: To develop a new type of optical computer-aided surgery (CAS) device that overcomes some of the restrictions of common systems and to examine its accuracy and usability under laboratory and intraoperative conditions. Study Design: Prospective study using laboratory experiments and intraoperative data collection. Methods: An optical CAS system applying passive optical markers for coordinate determination was developed. Laboratory accuracy measurements were obtained on a Plexiglas model with known coordinates of fiducial markers, before and after predefined table movements. Intraoperative accuracy measurements were recorded from 24 patients undergoing endonasal surgery of the para…

Validation of the Spanish version of the Problem Areas in Diabetes (PAID-SP) Scale

2014

This study aimed to assess the psychometric properties of the Spanish version of the Problem Areas in Diabetes (PAID-SP) Scale. Data were collected from patients with type 1 and type 2 diabetes. The findings suggested that the PAID-SP is a reliable and valid measure of diabetes-specific emotional problems.

Detection of Mycoplasma sp. in bronchoalveolar lavage of AIDS patients with pulmonary infiltrates.

1996

We examined 486 bronchoalveolar lavages (BAL) including 32 from AIDS patients with pulmonary infiltrates and 20 from patients with leukemia or after transplantation. Mycoplasmas were found in 4/32 (12.5%) HIV-positive patients compared to 4/454 (0.9%) HIV-negative patients (p0.001). All of these four HIV-positive patients suffered from advanced infection (CD4 counts100/microL) and developed complications (Pcp, n = 2, recurrent bacterial pneumonia, n = 1, pulmonary Kaposi sarcoma, n = 1). No mycoplasmas were detected in 20 immunosuppressed patients with leukemia or after transplantation. Our data indicate that AIDS patients may be more often colonised or infected by mycoplasmas than HIV-nega…

Peer-Led or Expert-Led Intervention in HIV Prevention Efficacy? A Randomized Control Trial Among Spanish Young People to Evaluate Their Role

2017

HIV new infections still affect young people around the world. In this context, behavioral interventions seem to be effective in promoting safe sex although some conditions are still inconclusive in different regions. For example, there is insufficient evidence about who may be the best facilitator. For this reason, this study evaluates the effectiveness of peer and expert facilitators for HIV prevention aimed at Spanish young people. For this purpose 225 Spanish college students, aged between 18 and 25 (74.20% women and 25.80% men), were involved in an experimental design to evaluate the facilitators’ effect in a brief intervention for HIV prevention. Participants’ results were measured b…

Detection of human immunodeficiency virus-1 DNA, RNA and antibody, and occult blood in inactivated saliva: Availability of the filter paper disk meth…

1996

Eighty three samples of saliva were collected from 60 subjects who were asymptomatic carriers of AIDS related complex (ARC) and AIDS. They included hemophiliacs, homosexuals and heterosexuals. Occult blood, human immunodeficiency virus-1 (HIV-1) antibody and DNA were assayed after heat treatment at 56 degrees C by strip method, particle agglutination and polymerase chain reaction (PCR), respectively. HIV-1 RNA was assayed by reverse transcription (RT)-PCR after heat treatment at 56 degrees C or 90 degrees C, or after application to filter paper disks with drying and heat treatment at 90 degrees C. Positive results were found in 53% (occult blood), 73% (HIV-1 antibody), 23% (HIV-1 DNA, 56 de…

BYOTYPES AND RANDOMLY AMPLIFIED POLYMORPHIC DNA (RAPD) PROFILES OF SUBGINGIVAL CANDIDA ALBICANS ISOLATES IN HIV INFECTION

2005

ABSTRACT: A group of subgingival isolates of C. albicans recovered from Italian HIV-positive (HIV+) subjects were characterized both phenotypically and genotypically. Phenotyping of the isolates was carried out by a biotyping method based on the enzyme profiles, carbohydrate assimilation patterns and boric acid resistance of the yeasts. Genotyping was performed through randomly amplified polymorphic DNA (RAPD) analysis. Five biotypes were found among the 29 subgingival C. albicans strains examined. The predominant biotypes were A1R (55.17%), A1S (24.14%), and A2R (13.79%), while the biotypes A11R and A13R were represented by a single isolate each. RAPD profiles identified 15 genotypes among…

Relationship Between Human Leucocyte Antigen Class I and Class II and Chronic Idiopathic Urticaria Associated With Aspirin and/or NSAIDs Hypersensiti…

2006

Background. HLA genes play a role in the predisposition of several diseases. The aim was to analyze the prevalence of HLA class I phenotypes and HLA-DRB1*genotype in patients with CIU associated with ASA and NSAIDs hypersensitivity (AICU).Methods. 69 patients with AICU, and 200 healthy subjects.Results. Subjects with HLA-B44 and HLA-Cw5 antigens were more represented in patients with AICU than in control group. Subjects with HLA-A11, HLA-B13, HLACw4, and HLA-Cw7 antigen were more represented in control group than in patients with AICU. Multiple logistic regression demonstrated an association of HLA-Cw4 and HLA-Cw7 with a lower risk of AICU, whereas carriers of HLA-B44 phenotype had a higher…

Supporting Reporting: On the Positive Effects of Text- and Video-Based Awareness Material on Responsible Journalistic Suicide News Writing.

2016

Suicide is a global public health problem. Media impact on suicide is well confirmed and there are several recommendations on how media should and should not report on suicide to minimize the risk of copycat behavior. Those media guidelines have been developed to improve responsible reporting on suicide (RRS). Although such guidelines are used in several countries, we lack empirical evidence on their causal effect on actual journalistic news writing. We conducted an experiment with journalism students (N = 78) in Germany in which we tested whether exposure to awareness material promoting RRS influences news writing. As a supplement to the widely used text-based material, we tested the impac…
