- Four Years of Experience with the Sao Paulo University Medical School Community Garden(2018) DANTAS, Katia Cristina; ZEMBRUSKI, Paulo Sergio; KUBRUSLY, Marcia Saldanha; CARVALHO-OLIVEIRA, Regiani; MAUAD, ThaisThe School of Medicine, Sao Paulo University Community Garden (FMUSP Community Garden), formed in June 2013, occupies an area of 520 m(2). In the concreted area, vegetables and herbs are grown in large vessels (http://www.facebook.com/HortaDaFmusp). The garden runs on an agroecological basis using locally made compost (garden leaves and horse manure) and bio fertilizers provided by volunteers and the local restaurant (coffee powder). In the garden several herbs, medicinal plants, wild food plants and different types of seasonal vegetables are cultivated. The harvest is open for the entire community. Five medical students received financial support from the University to work 40 h per month to maintain the FMUSP Community Garden. Educational activities for the community include workshops (on medicinal herbs and wild food plants) and cooking events with students and volunteers including an elderly group, focused on healthy eating. In addition, a Ph.D. student conducted studies addressing the role of air pollution on urban gardens using the garden as an experimental site. In summary, the FMUSP Community Garden has provided sustainable, educational and research activities focused on sustainability and healthy eating in the medical campus, on a low budget, for the community. We believe this paper is important because it describes how this experience has benefited many health-related professionals and complements medical teaching. The FMUSP Community Garden has shown that agriculture in large urban centers is possible. The results were very promising, involving students, staff, patients and the surrounding community.
- Comparative analysis of diagnostic methods for the detection of Cryptococcus neoformans meningitis(2023) DANTAS, Katia Cristina; FREITAS-XAVIER, Roseli Santos de; LOMBARDI, Suzete Cleusa Ferreira Spina; MENDRONI JUNIOR, Alfredo; SILVA, Marcos Vinicius da; CRIADO, Paulo Ricardo; FREITAS, Vera Lucia Teixeira de; ALMEIDA, Terezinha Morato Bastos deAuthor summaryCryptococcal meningitis is an infectious disease of global importance with high morbidity and mortality, especially among individuals with HIV/AIDS. While there have been improvements in the last two decades in the diagnosis of Cryptococcus neoformans, the methods presently employed are problematic for public hospitals in Brazil and other locations due to their extreme cost. In this study, we present a low-cost option for detection and identification of C. neoformans in noninvasive serum sample in immunosuppressed individuals, including those with HIV/AIDS. A nested PCR (5.8SrDNA-ITS) associated with the latex agglutination test has high precision in detection of suspected Cryptococcus spp. BackgroundCryptococcosis is a devastating opportunistic infection in immunocompromised individuals, primarily in people living with HIV/AIDS. This study evaluated a protocol for the early diagnosis of meningitis due to C. neoformans, utilizing established molecular techniques from serum and CSF samples. MethodsThe 18S and 5.8S (rDNA-ITS) sequence-specific nested PCR assays were compared with direct India ink staining and the latex agglutination test for detection of C. neoformans in serum and cerebrospinal fluid (CSF) from 49 Brazilian suspected meningitis patients. Results were validated with samples obtained from 10 patients negative for cryptococcosis and HIV, and by analysis of standard C. neoformans strains. Principal findingsThe 5.8S DNA-ITS PCR was more sensitive (89-100%) and specific (100%) than the 18S rDNA PCR and conventional tests (India ink staining and latex agglutination) for identification of C. neoformans. While the 18S PCR exhibited a sensitivity (72%) similar to that of the latex agglutination assay in serum samples, it was superior to the latex agglutination assay when testing CSF, with a sensitivity of 84%. However, the latex agglutination was superior to the 18SrDNA PCR in specificity in CSF (92%). The 5.8S DNA-ITS PCR yielded the highest levels of accuracy (96-100%) of any test for detection (serological and mycological) of C. neoformans in both serum and CSF. ConclusionUse of the nested 5.8S PCR was superior to other techniques for the diagnosis of cryptococcosis. The possibility of using serum, a non-invasively collected material, in a targeted 5.8S PCR analysis to identify Cryptococcus spp. is recommended, especially in immunosuppressed patients. Our results indicate that nested 5.8S PCR can increase the diagnostic capability of cryptococcosis, and we suggest its use to monitor patients in the future.
