RESUMO

Traumatic brain injury (TBI) is a neurotrauma with a complex pathophysiology caused by an external mechanical force. This global public health problem is a leading cause of death and disability in young adults. In this scenario, many models were developed to try to simulate human TBI. The weight drop model allows the investigation of the pathophysiological cascades of TBI without surgical interference. In this protocol, a new closed-head weight-drop rat model consisting of a 48.5g weight projectile that free falls from 1.10m high onto the skull of the animals was built. We classify the present TBI model performed as moderately severe due to its mortality rate. Animals from TBI and Control (Sham) groups underwent weight for 7 days and temperature assessments within 1 hour after TBI and for 7 days. Results demonstrated that the TBI group showed less body weight gain in the days after the injury. Temperature oscillations within the first-hour post-injury and on the 3rd day after injury were observed. As the results of this study demonstrated similarity to human TBI vital parameters, this new adaptation of the Weight-drop model injury can be a suitable candidate for translational studies.•We developed a novel closed head focal traumatic brain injury using a projectile.•This TBI model does not require surgical intervention.•The validation of this method demonstrates that the vital parameters of the injured rats exhibit similarities with those of TBI patients.

RESUMO

Epidemiological studies show a strong correlation between diabetes and the increased risk of developing different cancers, including melanoma. In the present study, we investigated the impact of a streptozotocin (STZ)-induced hyperglycemic environment on B16F10-Nex2 murine melanoma development. Hyperglycemic male C57Bl/6 mice showed increased subcutaneous tumor development, partially inhibited by metformin. Tumors showed increased infiltrating macrophages, and augmented IL-10 and nitric oxide (NO) concentrations. In vivo neutralization of IL-10, NO synthase inhibition, and depletion of macrophages reduced tumor development. STZ-treated TLR4 KO animals showed delayed tumor development; the transfer of hyperglycemic C57Bl/6 macrophages to TLR4 KO reversed this effect. Increased concentrations of IL-10 present in tumor homogenates of hyperglycemic mice induced a higher number of pre-angiogenic structures in vitro, and B16F10-Nex2 cells incubated with different glucose concentrations in vitro produced increased levels of IL-10. In summary, our findings show that a hyperglycemic environment stimulates murine melanoma B16F10-Nex2 primary tumor growth, and this effect is dependent on tumor cell stimulation, increased numbers of macrophages, and augmented IL-10 and NO concentrations. These findings show the involvement of tumor cells and other components of the tumor microenvironment in the development of subcutaneous melanoma under hyperglycemic conditions, defining novel targets for melanoma control in diabetic patients.

RESUMO

This study evaluated clinical features of individuals with long COVID (5-8 months after diagnosis) who reported sleep and memory problems (62 cases) compared to those without (52 controls). Both groups had a similar mean age (41 vs. 39 years). Around 86% of the participants were non-hospitalized at the time of infection, and none of them were vaccinated at that point. Subsequently, both cases and controls received the vaccine; however, the vaccination rates differed significantly between the groups (30.7% vs. 51.0%). Cases and controls had similar rates of symptoms at acute COVID phase. However, cases were more likely to experience coryza, dyspnea, headache, and nausea/vomiting during long COVID. Regarding new-onset symptoms in long COVID, 12.9% of cases had dyspnea, and 14.5% experienced nausea/vomiting, whereas in the control group there were only 1.9% and 0.0%, respectively. Cases also had a significantly higher prevalence of persistent headache (22.6% vs. 7.7%), and dyspnea (12.9% vs. 0.0). In addition, cases also showed an increased rate of mental health complaints: disability in daily activities (45.2% vs. 9.6%; P < 0.001); concentration/sustained attention difficulties (74.2% vs. 9.6%; P < 0.001); anxiety-Generalized Anxiety Disorder 2-item scale (GAD-2) ≥ 3 (66.1% vs. 34.6%; P = 0.0013); and "post-COVID sadness" (82.3% vs. 40.4%; P < 0.001). We observed a significant correlation between sadness and anxiety in cases, which was not observed in controls (P=0.0212; Spearman correlation test). Furthermore, the frequency of concomitant sadness and anxiety was markedly higher in cases compared to controls (59.7% vs. 19.2%) (P < 0.0001; Mann-Whitney test). These findings highlight a noteworthy association between sadness and anxiety specifically in cases. In conclusion, our data identified concurrent psychological phenotypes in individuals experiencing sleep and memory disturbances during long COVID. This strengthens the existing evidence that SARS-CoV-2 causes widespread brain pathology with interconnected phenotypic clusters. This finding highlights the need for comprehensive medical attention to address these complex issues, as well as major investments in testing strategies capable of preventing the development of long COVID sequelae, such as vaccination.

RESUMO

Leprosy is a chronic infectious disease caused by the intracellular bacillus Mycobacterium leprae (M. leprae), which is known to infect skin macrophages and Schwann cells. Although adipose tissue is a recognized site of Mycobacterium tuberculosis infection, its role in the histopathology of leprosy was, until now, unknown. We analyzed the M. leprae capacity to infect and persist inside adipocytes, characterizing the induction of a lipolytic phenotype in adipocytes, as well as the effect of these infected cells on macrophage recruitment. We evaluated 3T3-L1-derived adipocytes, inguinal adipose tissue of SWR/J mice, and subcutaneous adipose tissue biopsies of leprosy patients. M. leprae was able to infect 3T3-L1-derived adipocytes in vitro, presenting a strong lipolytic profile after infection, followed by significant cholesterol efflux. This lipolytic phenotype was replicated in vivo by M. leprae injection into mice inguinal adipose tissue. Furthermore, M. leprae was detected inside crown-like structures in the subcutaneous adipose tissue of multibacillary patients. These data indicate that subcutaneous adipose tissue could be an important site of infection, and probably persistence, for M. leprae, being involved in the modulation of the innate immune control in leprosy via the release of cholesterol, MCP-1, and adiponectin.

RESUMO

Severe traumatic brain injury (sTBI) is an important cause of disability and mortality and affects people of all ages. Current scientific evidence indicates that motor dysfunction and cognitive impairment are the main limiting factors in patients with sTBI. Transcranial direct current stimulation (tDCS) seems to be a good therapeutic option, but when it comes to patients with sTBI, the results are inconclusive, and some protocols have not yet been tested. In addition, there is still a lack of information on tDCS-related physiological mechanisms, especially during the acute phase. In the present study, based on current evidence on tDCS mechanisms of action, we hypothesized that performing tDCS sessions in individuals with sTBI, especially in the acute and subacute phases, together with conventional therapy sessions, could improve cognition and motor function in this population. This hypothesis presents a new possibility for treating sTBI, seeking to elucidate the extent to which early tDCS may affect long-term clinical outcomes.

RESUMO

Introduction: traumatic brain injury is a global public health problem due to its severity and high rates of morbimortality worldwide. Identifying predictors associated with increased mortality and unfavorable functional outcomes after the traumatic brain injury event is crucial for minimizing morbidity and mortality rates. Therefore, this study aims to establish a protocol to investigate the predictors of mortality and functional recovery after severe traumatic brain injury in Brazil.Methods: The study will include all patients admitted for severe traumatic brain injury (Glasgow Coma Scale ≤ 8) at the State Hospital of Urgency and Emergency, which is the referral trauma hospital of Espirito Santo. The outcomes of interest are hospital mortality and functional recovery 24 months after hospital discharge. Subjects will be followed up at seventy-two hours, three months, six months, twelve months, and twenty-four months after the trauma. Morbidity will be determined by assessing: 1) the level of motor and cognitive disability, 2) functional impairment and quality of life, and 3) aspects of rehabilitation treatment. Additionally, the traumatic brain injury load, estimated by the years of life lost, will be calculated. Discussion: the results of this study will help identify variables that can predict morbidity and mortality, as well as diagnostic and therapeutic targets for patients with severe traumatic brain injury. Furthermore, the findings will have practical implications for: 1) the development of public policies, 2) investments in hospital infrastructure 3) understanding the socioeconomic impact of functional loss in the individuals.Study registration: the study received approval from the Ethics Committee of the Federal University of Espirito Santo under protocol number 4.222.002 on August 18, 2020.


Introdução: traumatismo cranioencefálico é um problema global de saúde pública devido à sua gravidade e altas taxas de morbimortalidade em todo o mundo. Identificar preditores associados ao aumento da mortalidade e desfechos funcionais desfavoráveis após o evento do traumatismo craniencefálico é primordial para minimizar as taxas de morbidade e mortalidade. Portanto, este estudo tem como objetivo estabelecer um protocolo para investigar os preditores de mortalidade e recuperação funcional após traumatismo cranioencefálico grave no Brasil. Métodos: este estudo tem como objetivo investigar os preditores de mortalidade e recuperação funcional em pacientes com traumatismo cranioencefálico, além de fornecer uma visão geral do traumatismo cranioencefálico no estado do Espírito Santo. O estudo abrangerá todos os pacientes internados por traumatismo cranioencefálico grave (Escala de Coma de Glasgow ≤ 8) no Hospital Estadual de Urgência e Emergência, o hospital de referência para traumas no Espírito Santo. Os desfechos de interesse incluem mortalidade hospitalar e recuperação funcional após 24 meses da alta hospitalar. Os participantes serão acompanhados em setenta e duas horas, três meses, seis meses, doze meses e vinte e quatro meses após o trauma. A morbidade será determinada pela avaliação de: 1) nível de incapacidade motora e cognitiva, 2) comprometimento funcional e qualidade de vida, e 3) aspectos do tratamento e reabilitação. Além disso, a carga de traumatismo cranioencefálico, estimada em anos de vida perdidos, será calculada. Discussão: os resultados deste estudo ajudarão a identificar variáveis que podem predizer a morbidade e a mortalidade após traumatismo cranioencefálico grave. Além disso, as descobertas terão implicações práticas para: 1) o desenvolvimento de políticas públicas, 2) investimentos em infraestrutura hospitalar e 3) compreensão do impacto socioeconômico da perda funcional nesses indivíduos. Registro do estudo: o estudo recebeu aprovação do Comitê de Ética da Universidade Federal do Espírito Santo sob o número de protocolo 4.222.002 em 18 de agosto de 2020

RESUMO

BACKGROUND: Rapid demographic, epidemiological, technological, cultural/behavioural, and educational transitions, as they become more complex, demand new integrated and complementary professional skills and abilities. Interprofessional Education (IPE) is a promising alternative to deal with these changes, especially in courses in the health area. This systematic review was to explore the potentialities and limitations of IPE, from the perspective of undergraduate students, through a thematic synthesis of qualitative studies. METHODS: A thematic synthesis of qualitative studies was conducted. The question elaborated for this review was: "What is the impact of interprofessional education on the teaching and learning of students in the health area inserted in Higher Education Institutions?". The search strategy was performed in the electronic databases PubMed, Latin American and Caribbean Literature in Health Sciences (LILACS), Cochrane Library, and Scientific Electronic Library Online (SciELO). In addition, searches were carried out in grey literature on the ERIC platforms, ProQuest Disserts and Theses, and Academic Google. The assessment of the quality of the studies was carried out using the Critical Appraisal Skills Programme tool. Data were summarized through thematic synthesis. From the databases, 8,793 studies were identified. After standardized filters procedures, critical summaries, and assessment of relevance to the eligibility criteria, 14 articles were included. RESULTS: The synthesis of the studies revealed the potential of this teaching approach, arranged in three analytical themes: learning from each other and about them; the value of education and interprofessional practice; patient-centred health care. On the other hand, some limitations were also identified, such as barriers related to EIP; the difficulties related to teaching methodologies. CONCLUSION: Overcoming the identified limitations can enhance the results of the IPE, in view of its impact on the education of students and on the health care of the population.

RESUMO

Introdução: A perda parcial ou total de um membro causa inúmeros desafios físicos e psicossociais, incluindo redução na qualidade de vida, bem como limitações e restrições na participação social do indivíduo. Objetivos: Este estudo teve como objetivo descrever o perfil epidemiológico, coletar dados da amputação e da reabilitação dos pacientes atendidos no Centro de Reabilitação Física do Espírito Santo (CREFES). Métodos: Trata-se de um estudo retrospectivo e descritivo que consistiu na análise de 509 prontuários devidamente preenchidos de pacientes amputados atendidos na Unidade de Trabalho de Órteses e Próteses do CREFES de 2012 a 2018. Resultados: Observou-se predomínio de amputados do sexo masculino (72%), maiores de 60 anos (36%) e de amputações de membro inferior (94,4%). A principal etiologia das amputações foi a vascular (59%), seguida de acidentes de trânsito (23%). O tempo de início de reabilitação foi em média 27 meses e 34,97% chegaram de fato à protetização. Conclusão: As principais etiologias de amputação são de natureza preveníveis. Consiste, portanto, em um problema de saúde pública que requer atenção de uma equipe multidisciplinar.

RESUMO

OBJECTIVE: This systematic review aimed to examine the effects of home-based exercises in comparison with centre-based exercises for improving the paretic upper limb after stroke. DATA SOURCES: AMED, MEDLINE, EMBASE CINAHL, Cochrane, PsycINFO, and PEDro databases. REVIEW METHODS: Only randomized clinical trials were included. Participants in the reviewed studies were adults at any time after stroke. The experimental intervention was home-based exercises compared with centre-based exercises. Outcome data related to strength, motor recovery, dexterity, activity, and participation were extracted from the eligible trials and combined in meta-analyses. The quality of included trials was assessed by the PEDro scores. The quality of evidence was determined according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. RESULTS: Eight trials, involving 488 participants, were included. Most trials (63%) delivered semi-supervised interventions (amount of supervision 3-43%), and three trials provided full supervision. Random-effects meta-analyses provided moderate- to high-quality evidence that home- and centre-based exercises provide similar effects on motor recovery (MD 1.4 points; 95% CI -0.9 to 3.8), dexterity (MD -0.01 pegs/s; 95% CI -0.04 to 0.05), upper limb activity performance (SMD -0.04; 95% CI -0.25 to 0.18), and quality of movement (0.1 points; 95% CI -0.2 to 0.4). Effects on strength were also similar but the quality of the evidence was rated as low. No trials examined effects on participation. CONCLUSION: Effects of home-based prescribed exercises on upper limb motor recovery, dexterity, and activity are likely to be similar to improvements obtained by centre-based exercises after stroke.

RESUMO

Astrocytoma is the most common and aggressive tumor of the central nervous system. Genetic and environmental factors, bacterial infection, and several other factors are known to be involved in gliomagenesis, although the complete underlying molecular mechanism is not fully understood. Tumorigenesis is a multistep process involving initiation, promotion, and progression. We present a human model of malignant astrocyte transformation established by subjecting primary astrocytes from healthy adults to four sequential cycles of forced anchorage impediment (deadhesion). After limiting dilution of the surviving cells obtained after the fourth deadhesion/readhesion cycle, three clones were randomly selected, and exhibited malignant characteristics, including increased proliferation rate and capacity for colony formation, migration, and anchorage-independent growth in soft agar. Functional assay results for these clonal cells, including response to temozolomide, were comparable to U87MG-a human glioblastoma-derived cell lineage-reinforcing malignant cell transformation. RNA-Seq analysis by next-generation sequencing of the transformed clones relative to the primary astrocytes revealed upregulation of genes involved in the PI3K/AKT and Wnt/ß-catenin signaling pathways, in addition to upregulation of genes related to epithelial-mesenchymal transition, and downregulation of genes related to aerobic respiration. These findings, at a molecular level, corroborate the change in cell behavior towards mesenchymal-like cell dedifferentiation. This linear progressive model of malignant human astrocyte transformation is unique in that neither genetic manipulation nor treatment with carcinogens are used, representing a promising tool for testing combined therapeutic strategies for glioblastoma patients, and furthering knowledge of astrocytoma transformation and progression.

RESUMO

The current research aims to perform a comparative evaluation of vegetable matter involved lesions with oral parasitic infections found in oral mucosa, presenting histochemical methods to differentiate their microscopic similarities. Eight cases were selected out of a sample of 1.975 reports from a single Oral and Maxillofacial Pathology Service of the author's institution from 2012 to 2019. Specimens were examined by hematoxylin and eosin staining (HE), periodic acid-Schiff (PAS) staining, Gomori-Grocott staining, Ziehl-Neelsen staining, Giemsa, and mucicarmine staining. Microscopic analysis included fluorescence, polarized light, and confocal microscopy. Microscopically, in HE coloration, hookworm eggs showed as eosinophilic. Inflammatory multinucleated giant cells and lymphocytes, were usually related to the nematode eggs, forming an intense inflammatory infiltrate. Biofluorescent properties of eggs and larvae revealed to be sensitive in the detection of parasitic structures contrasting with the inflamed connective tissue. Vegetable presence was confirmed by polarized light microscopy and it was found to be associated with microbial biofilms. Confocal microscopy has showed to be an excellent method for morphotype differentiation of parasitic eggs. Parasitic infection and vegetable matter displayed similarities in the inflammatory response, but the latter can rot and agglomerate biofilms. The microscopic diagnosis of such infections requires the interpretation of challenging morphological features since the parasites are usually sectioned and mixed with an inflammatory reaction. These histochemical approaches proved to be excellent to distinguish both lesions.

RESUMO

The present study was carried out to evaluate the substitution of synthetic performance enhancers by ethanolic propolis extract (EPE) in the diet of broilers and their effects on performance, carcass yield, noble cuts, viscera and bed quality. A completely randomized design was used, with four treatments and six replicates each, totaling 24 experimental plots with 20 birds each. The experimental treatments were: negative control, without the inclusion of performance improvement and EPE-free; positive control, containing avilamycin performance enhancer; Inclusion of 0.1% of EPE and; Inclusion of 0.2% EPE. The analyzed data were submitted to analysis of variance and applied the SNK test at 5% probability. There was no effect of the inclusion of additives on feed intake and feed conversion in the periods from 1 to 7, 1 to 21, and from 1 to 42 days of age. Weight gain was lower in birds receiving feed with the inclusion of 0.1% EPE in the period from 1 to 7 days, not differing from the other treatments in the other evaluation periods. Carcass characteristics, cuts, and viscera and bed moisture were not influenced by the treatments used. The inclusion of ethanol extract from propolis as a performance enhancer up to 42 days of age provided similar results to the use of performance enhancers based on avilamycin, thus being an efficient substitute in poultry production.
