ABSTRACT The Scientists of Tomorrow/ Cientistas do Amanhã project is an immersive science training program developed by the Program of Post-Graduation in Health Sciences at Hospital Israelita Albert Einstein. This program was conducted in partnership with Volunteering and Escola Municipal de Ensino Fundamental Professor Paulo Freire in Paraisópolis, São Paulo, Brazil. The Scientists of Tomorrow Program comprised a short training period conducted in May 2022 involving 37 students, and a long training period from August to December 2022, which included 15 students. It aimed to popularize science through practical activities; transfer knowledge to young students; sensitize and guide them to pursue academic-scientific careers; reduce stereotypes about scientific work and scientists; and help students understand the social, political, and ethical roles of science within society. All activities were led by postgraduate students and professors from our postgraduate program, physicians, nurses, physiotherapists, biomedicals, and veterinarians from Hospital Israelita Albert Einstein, as well as medical students from Faculdade Israelita de Ciências da Saúde Albert Einstein . Activities in the short training included lectures on cinema and science, strategies to combat fake news, non-violent communication, innovation, design-thinking framework, and developing a scientific project. During the long training period, discussions were focused on nanotechnology, animal research, big data, bioinformatics, meditation, blood and bone marrow donation, telemedicine, sex and sexually-transmitted infections, rehabilitation, career opportunities, and scientific integrity. In addition, practical activities were further expanded using optical and confocal microscopy, cytometry, and basic concepts regarding the structure and function of living cells. The program also included the launching of the open-air outreach Education E-natureza activity, which turned students into ambassadors of nature. In conclusion, the Scientists of Tomorrow Program was innovative and enabled young students to learn that science is a collective activity that can enhance public health.

ABSTRACT Background: Carbapenem-resistant Acinetobacter baumannii (CRAB) is a growing threat to public health. Methods: A 3-year retrospective study was conducted to evaluate the prevalence and lethality of multidrug-resistant (MDR) A. baumannii isolated from Brazilian patients. Results: In this study, 219 Acinetobacter baumannii isolates were identified, of which 70.8% (155/219) were isolated from patients hospitalized in intensive care units. Of these, 57.4% (n = 89/155) were assessed, of which 92.1% (82/89) were carbapenem-resistant, and 49 were classified as infected. The lethality rate was 79.6% (39/49). Conclusions: We highlight the need of an effective epidemiological surveillance measure to contain the dissemination of CRAB in the hospital environment.

ABSTRACT The present study proposes to characterize the parasites isolated during the initial phase of production in fish farms located in Mato Grosso do Sul in the central-western region of Brazil, using histopathology analysis and molecular techniques. A total of 340 hybrid surubim fish (Pseudoplatystoma reticulatum × P. corruscans) from four farms were examined during the co-feeding phase. Histopathology analysis showed that 10.9% (n = 37) of the fish were infected with parasites. Branchitis, lifting epithelium, hypertrophy of epithelial cells, lamellar fusion, aneurisms and infection in the bone tissue of the gill filament was observed. The parasite species was determined by amplification of the 18S rRNA gene followed by sequencing. The phylogenetic analysis of nucleotide sequences indicates a close relationship (99.6%) with Henneguya pseudoplatystoma reported to be infecting the hybrid Pseudoplatystoma. This study demonstrates the occurrence of H. pseudoplatystoma in hybrid surubim (P. reticulatum × P. corruscans) during the co-feeding phase in fish farms in Mato Grosso do Sul. Also, molecular techniques provide a faster and sensitive method to identify fish parasites, and may assist in the development of new management techniques aimed at improving the sanitary conditions contributing to the reduction of mortality rates in these animals.

Abstract INTRODUCTION: The increase in the prevalence of multidrug-resistant Acinetobacter baumannii infections in hospital settings has rapidly emerged worldwide as a serious health problem. METHODS: This review synthetizes the epidemiology of multidrug-resistant A. baumannii, highlighting resistance mechanisms. CONCLUSIONS: Understanding the genetic mechanisms of resistance as well as the associated risk factors is critical to develop and implement adequate measures to control and prevent acquisition of nosocomial infections, especially in an intensive care unit setting.
