Revisión de la literatura científica de la radio universitaria como instrumento de educación mediática

Esta investigación tiene como objetivo realizar una revisión bibliométrica de la radio universitaria desde una perspectiva educomunicativa, tanto en el ámbito nacional como internacional. Como metodología, se han analizado el contenido de un total de 276 registros del repositorio Web of Science. El análisis de la información se clasificó en cuatro categorías temáticas: primeros estudios científicos de la radio en la universidad; tipologías de los programas radiofónicos en la universidad; países con mayor interés en los estudios sobre la radio universitaria y la radio universitaria y sus programas en las universidades españolas. Tras la revisión de los artículos llegamos a la conclusión de que las publicaciones analizadas plantean el interés de profundizar en la radio como instrumento educomunicativo, con el fin de mejorar la competencia mediática de los universitarios. This research aims to conduct a bibliometric review of university radio from an educommunicative perspective, both nationally and internationally. As a methodology, the contents of a total of 276 records of the Web of Science repository have been analyzed. The information analysis was classified into four thematic categories: first scientific studies of radio in the university; typologies of radio programs in the university; countries with greater interest in studies on university radio and university radio and its programs in Spanish universities. After reviewing the articles we conclude that the analyzed publications raise the interest of deepening in the radio as an educonununicative tool, in order to improve the media competence of university students

Withdrawal of maintenance therapy for cytomegalovirus retinitis in AIDS patients exhibiting immunological response to HAART

BACKGROUND: Before the introduction of highly active antiretroviral therapy (HAART), CMV retinitis was a common complication in patients with advanced HIV disease and the therapy was well established; it consisted of an induction phase to control the infection with ganciclovir, followed by a lifelong maintenance phase to avoid or delay relapses. METHODS: To determine the safety of CMV maintenance therapy withdrawal in patients with immune recovery after HAART, 35 patients with treated CMV retinitis, on maintenance therapy, with CD4+ cell count greater than 100 cells/mm³ for at least three months, but almost all patients presented these values for more than six months and viral load < 30000 copies/mL, were prospectively evaluated for the recurrence of CMV disease. Maintenance therapy was withdrawal at inclusion, and patients were monitored for at least 48 weeks by clinical and ophthalmologic evaluations, and by determination of CMV viremia markers (antigenemia-pp65), CD4+/CD8+ counts and plasma HIV RNA levels. Lymphoproliferative assays were performed on 26/35 patients. RESULTS: From 35 patients included, only one had confirmed reactivation of CMV retinitis, at day 120 of follow-up. No patient returned positive antigenemia tests. No correlation between lymphoproliferative assays and CD4+ counts was observed. CONCLUSION: CMV retinitis maintenance therapy discontinuation is safe for those patients with quantitative immune recovery after HAART

Clinical and epidemiological aspects of HTLV-II infection in São Paulo, Brazil: presence of Tropical Spastic Paraparesis/HTLV-Associated Myelopathy (TSP/HAM) simile diagnosis in HIV-1-co-infected subjects Aspectos clínicos e epidemiológicos da infecção pelo vírus linfotrópico de células T humanas do tipo 2 (HTLV-II) em São Paulo, Brasil: presença de paraparesia espástica tropical/mielopatia associada ao HTLV em pacientes co-infectados pelo HIV-1

In this study, the epidemiological and clinical features observed in solely HTLV-II-infected individuals were compared to those in patients co-infected with HIV-1. A total of 380 subjects attended at the HTLV Out-Patient Clinic in the Institute of Infectious Diseases "Emilio Ribas" (IIER), São Paulo, Brazil, were evaluated every 3-6 months for the last seven years by infectious disease specialists and neurologists. Using a testing algorithm that employs the enzyme immuno assay, Western Blot and polymerase chain reaction, it was found that 201 (53%) were HTLV-I positive and 50 (13%) were infected with HTLV-II. Thirty-seven (74%) of the HTLV-II reactors were co-infected with HIV-1. Of the 13 (26%) solely HTLV-II-infected subjects, urinary tract infection was diagnosed in three (23%), one case of skin vasculitis (8%) and two cases of lumbar pain and erectile dysfunction (15%), but none myelopathy case was observed. Among 37 co-infected with HIV-1, four cases (10%) presented with tropical spastic paraparesis/HTLV-associated myelopathy (TSP/HAM) simile. Two patients showed paraparesis as the initial symptom, two cases first presented with vesical and erectile disturbances, peripheral neuropathies were observed in other five patients (13%), and seven (19%) patients showed some neurological signal or symptoms, most of them with lumbar pain (five cases). The results obtained suggest that neurological manifestations may be more frequent in HTLV-II/HIV-1-infected subjects than those infected with HTLV-II only.<br>Neste estudo, as características epidemiológicas e clínicas observadas nos indivíduos infectados pelo HTLV-II foram comparadas com os pacientes co-infectados com HIV-1. Um total de 380 indivíduos atendidos na clínica do Ambulatório HTLV do Instituto de Infectologia "Emilio Ribas" (IIER), São Paulo, Brasil, foram avaliados a cada 3-6 meses nos últimos sete anos por especialistas em doenças infecciosas e neurologistas. Usando um algoritmo que emprega ensaio imunoenzimático, Western Blot e reação em cadeia de polimerase, foram incluídos 201 (53%) pacientes infectados pelo HTLV-I e 50 (13%) infectados pelo HTLV-II. Trinta e sete (74%) eram co-infectados pelo HTLV-II e HIV-1. Dos 13 (26%) indivíduos unicamente infectados pelo HTLV-II, infecção do trato urinário foi diagnosticada em três, um com vasculite e em dois casos dor lombar e disfunção erétil mas nenhum caso de mielopatia foi observado. Entre 37 pacientes co-infectados com HIV-1, quatro (10%) casos apresentaram com paraparesia espástica tropical/mielopatia associada ao HTLV similar. Dois casos mostraram paraparesia como sintoma inicial, dois outros casos se apresentaram primeiramente com distúrbios vesical e erétil e as neuropatias periféricas foram observadas em cinco pacientes (13%). Outros sete (19%) pacientes mostraram algum sinal ou sintoma neurológico, a maioria deles com dor lombar (cinco casos). Os resultados sugerem que as manifestações neurológicas podem ser mais freqüentes em indivíduos co-infectados pelo HTLV-II/HIV-1 do que nos indivíduos infectados somente pelo HTLV-II
