RESUMEN

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. In Brief Rangel et al. enumerated the Scientists of Tomorrow/Cientistas do Amanhã program, an immersive science initiative conducted in collaboration with a public school. The program, which involved 15 students, aimed to promote science, share knowledge, inspire academic paths, and underscore societal impacts. Led by postgraduates, professors, and healthcare experts, the program included diverse lectures and practical laboratory activities. Highlights Every research endeavor commences with a fundamental question. Sharing of findings by researchers and students contributes toward the expansion of knowledge. Teaching scientific methodology is a pivotal step in nurturing critical thinking skills. Science permeates our daily lives and plays a crucial role in addressing societal issues.

RESUMEN

Specific virulence factors that likely influence C. acnes invasion into deep tissues remain to be elucidated. Herein, we describe the frequency of C. acnes identification in deep tissue specimens of patients undergoing clean shoulder surgery and assess its phenotypic and genetic traits associated with virulence and antibiotic resistance patterns, compared with isolates from the skin of healthy volunteers. Multiple deep tissue specimens from the bone fragments, tendons, and bursa of 84 otherwise healthy patients undergoing primary clean-open and arthroscopic shoulder surgeries were aseptically collected. The overall yield of tissue sample cultures was 21.5% (55/255), with 11.8% (30/255) identified as C. acnes in 27.3% (23/84) of patients. Antibiotic resistance rates were low, with most strains expressing susceptibility to first-line antibiotics, while a few were resistant to penicillin and rifampicin. Phylotypes IB (73.3%) and II (23.3%) were predominant in deep tissue samples. Genomic analysis demonstrated differences in the pangenome of the isolates from the same clade. Even though strains displayed a range of pathogenic markers, such as biofilm formation, patients did not evolve to infection during the 1-year follow-up. This suggests that the presence of polyclonal C. acnes in multiple deep tissue samples does not necessarily indicate infection.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Pseudomonas aeruginosa is an important opportunistic pathogen in hospitals, responsible for various infections that are difficult to treat due to intrinsic and acquired antibiotic resistance. Here, 20 epidemiologically unrelated strains isolated from patients in a general hospital over a time period of two decades were analyzed using whole genome sequencing. The genomes were compared in order to assess the presence of a predominant clone or sequence type (ST). No clonal structure was identified, but core genome-based single nucleotide polymorphism (SNP) analysis distinguished two major, previously identified phylogenetic groups. Interestingly, most of the older strains isolated between 1994 and 1998 harbored exoU, encoding a cytotoxic phospholipase. In contrast, most strains isolated between 2011 and 2016 were exoU-negative and phylogenetically very distinct from the older strains, suggesting a population shift of nosocomial P. aeruginosa over time. Three out of 20 strains were ST235 strains, a global high-risk clonal lineage; these carried several additional resistance determinants including aac(6')Ib-cr encoding an aminoglycoside N-acetyltransferase that confers resistance to fluoroquinolones. Core genome comparison with ST235 strains from other parts of the world showed that the three strains clustered together with other Brazilian/Argentinean isolates. Despite this regional relatedness, the individuality of each of the three ST235 strains was revealed by core genome-based SNPs and the presence of genomic islands in the accessory genome. Similarly, strain-specific characteristics were detected for the remaining strains, indicative of individual evolutionary histories and elevated genome plasticity.
