Attitudes of Elements of the Academic Community in Regard to the Rapid Test of HIV/AIDS

Background: Knowing one’s own seropositivity status of HIV/AIDS is important. Seropositivity can be determined by a rapid HIV/AIDS test. Attitudes towards a rapid test of HIV/AIDS show a predisposition to perform the analysis.

. Attitudes of Elements of the Academic Community in Regard to the Rapid Test of HIV/AIDS

Background: Knowing one’s own seropositivity status of HIV/AIDS is important. Seropositivity can be determined by a rapid HIV/AIDS test. Attitudes towards a rapid test of HIV/AIDS show a predisposition to perform the analysis. Objective: This study investigated, the attitudes of students and staff in a Portuguese university toward rapid HIV/AIDS test. Methods: In a convenience sample, the data was collected on campus in three consecutive years. A selfadministered structured questionnaire was used for data collection. A validated scale for Portuguese students was applied. A sample of 947 (86.3%) students and 150 (13.7%) teaching and non-teaching staff participated. The average age was 24.30 years-old (SD=8.64). Non-parametric tests were applied. Results: Attitudes of professors and non-teaching staff are more favorable in relation to the rapid test of HIV/AIDS, compared to students. Attitudes are also more favorable in the first year in which the study was conducted with both employees and students. The male students express more traditional attitudes. Students of nursing polo have expressed more favorable attitudes to the rapid test of HIV/AIDS. Conclusion: The attitudes towards rapid test of HIV/AIDS are generally favorable. It is necessary to conduct further research considering professors and other university staff. Improving favorable attitudes toward rapid HIV/AIDS test must be a positive fact for health.

DNA barcoding: an effective tool to overcome morphological identification constraints in the assessment of the ecological quality

DNA barcoding has the potential to overcome taxonomic challenges in biological community assessments. However, fulfilling that potential requires successful amplification of a large and unbiased portion of the community. In this study, we attempted to identify mitochondrial gene cytochrome c oxidase I (COI) barcodes from 1024 benthic invertebrate specimens belonging to 54 taxa from low salinity environments of the Mira estuary and Torgal riverside (SW Portugal). Up to 17 primer pairs and several reaction conditions were attempted among specimens from all taxa, with amplification success defined as a single band of approximately 658 bp visualized on a pre-cast agarose gel, starting near the 5' end of the COI gene and suitable for sequencing. Amplification success was achieved for 99.6% of the 54 taxa, though no single primer was successful for more than 88.9% of the taxa. However, only 68.5% of the specimens within these taxa successfully amplified. Inhibition factors resulting from a non-purified DNA extracted and inexistence of species-specific primers for COI were pointed as the main reasons for an unsuccessful amplification. These results suggest that DNA barcoding can be an effective tool for application in low salinity environments where taxa such as chironomids and oligochaetes are challenging for morphological identification. Nevertheless, its implementation is not simple, as methods are still being standardized and multiple species
