ABSTRACT
Advances in Brazilian science made the country reach the 13th position in the world scientific production, and, in 2020, o Brazil was responsible for 2.39% of the world scientific production, reaching the 11th position among the countries that most published about COVID-19. The aim of this study was to contribute to and reflect on the issue of health researchers and graduate students in the scenario of COVID-19 pandemic. This pandemic highlighted the importance of science in the outcome of public policies and the fragility of the research system in Brazil, where the workforce is mainly composed of graduate students, who often do not have ideal working conditions and are not included in the response plans to global public health emergencies. This text brings a reflection and a questioning on the role of health researchers and graduate students and reinforces the importance of discussing the work of researchers/scientists in a period of great uncertainty in society.

Os avanços na ciência brasileira alcançaram a 13ª posição na produção científica mundial, e, em 2020, o Brasil foi responsável por 2,39% da produção científica mundial, alcançando a 11a posição entre os países que mais publicaram sobre a COVID-19. O objetivo deste trabalho foi contribuir e refletir sobre o debate dos pesquisadores e pós-graduandos da área de saúde no cenário pandêmico da COVID-19. A pandemia da COVID-19 evidenciou a importância da ciência no desfecho de políticas públicas e a fragilidade do sistema de pesquisa no Brasil, em que a maior força de trabalho se concentra em pós-graduandos, que muitas vezes não possuem condições ideais de trabalho e não estão inseridos nos planos de resposta às emergências globais de saúde pública. Este texto traz uma reflexão e problematização sobre o papel dos pesquisadores e pós-graduandos em saúde e reforça a importância de discutir a atuação de pesquisadores/cientistas em um período de grandes incertezas na sociedade.
ABSTRACT
A 30-year-old female patient presented with multiple sores in the oral cavity and facial skin associated with pain. Clinical examination revealed an ulcerative lesion associated with nondetachable white plaques on the bilateral buccal mucosa, soft palate, bilateral retromolar trigone, upper lip frenum, and lingual ventral surface and borders. The gingival mucosa showed erythema and desquamative epithelium positive for Nikolsky's sign and dryness of the mucosa. The patient tested negative for COVID-19. The differential diagnosis included pemphigus vulgaris, lichen planus, and lupus erythematosus. After incisional biopsy, the histopathologic analysis confirmed the diagnosis of pemphigus vulgaris. The patient was treated with systemic immunosuppressive drugs and photobiomodulation. After 2 months of treatment, the patient presented regression of ulcerations, maintaining white plaques on the retromolar trigone bilaterally and upper lip frenum, erythema on the right soft palate, absence of pain and burning mouth, at 10-month follow-up. Photobiomodulation was an excellent adjuvant for pain control and remission of oral lesions.
ABSTRACT
This prospective cohort study aims to analyze the surveillance of COVID-19 at a single hematopoietic stem cell transplantation (HSCT) center in Brazil, in 29 patients undergoing allogeneic HSCT and 57 healthcare workers (nurses and dentists), through viral shedding of SARS-CoV-2 in saliva and plasma and seroprevalence of anti-SARS-CoV-2 IgG. In addition, we report two cases with prolonged persistent detection of SARS-CoV-2 without seroconversion. The sample collection was performed seven times for patients and five times for healthcare workers. Only two patients tested positive for SARS-CoV-2 in their saliva and plasma samples (6.9%) without seroconversion. All healthcare workers were asymptomatic and none tested positive. Two patients (6.9%) and four nurses (8%) had positive serology. No dentists had positive viral detection or positive serology. Our results reflect a low prevalence of positive RT-PCR and seroprevalence of SARS-CoV-2 in patients and healthcare workers at a single HSCT center. Results have also corroborated how the rigorous protocols adopted in transplant centers were even more strengthened in this pandemic scenario.
