Association of a Skin Dressing Made With the Organic Part of Marine Sponges and Photobiomodulation on the Wound Healing in an Animal Model.

The present study aims to characterize and to evaluate the biological effects of a skin dressing manufactured with the organic part of the Chondrilla caribensis marine sponge (called spongin-like collagen (SC)) associated or not to photobiomodulation (PBM) on the skin wound healing of rats. Skin dressings were manufactured with SC and it was characterized using scanning electron microscopy (SEM) and a tensile assay. In order to evaluate its biological effects, an experimental model of cutaneous wounds was surgically performed. Eighteen rats were randomly distributed into three experimental groups: control group (CG): animals with skin wounds but without any treatment; marine collagen dressing group (DG): animals with skin wounds treated with marine collagen dressing; and the marine collagen dressing + PBM group (DPG): animals with skin wounds treated with marine collagen dressing and PBM. Histopathological, histomorphometric, and immunohistochemical evaluations (qualitative and semiquantitative) of COX2, TGFß, FGF, and VEGF were done. SEM demonstrates that the marine collagen dressing presented pores and interconnected fibers and adequate mechanical strength. Furthermore, in the microscopic analysis, an incomplete reepithelialization and the presence of granulation tissue with inflammatory infiltrate were observed in all experimental groups. In addition, foreign body was identified in the DG and DPG. COX2, TGFß, FGF, and VEGF immunostaining was observed predominantly in the wound area of all experimental groups, with a statistically significant difference for FGF immunostaining score of DPG in relation to CG. The marine collagen dressing presented adequate physical characteristics and its association with PBM presented favorable biological effects to the skin repair process.

Post-parotidectomy facial nerve rehabilitation outcomes: Comparison between benign and malignant neoplasms.

BACKGROUND: Facial nerve dysfunction can be a devastating trouble for post-parotidectomy patients. OBJECTIVE: To assess rehabilitation outcomes concerning patients with post-parotidectomy facial nerve dysfunction, comparing benign versus malignant neoplasms. METHODS: Prospective study enrolling adults who underwent parotidectomy with facial nerve sparing between 2016 and 2020. The Modified Sunnybrook System (mS-FGS) was used for facial assessments. Physiotherapy began on the first post-operative day with a tailored program of facial exercises based on Neuromuscular Retraining, to be performed at home 3 times/day. From the first outpatient consultation, Proprioceptive Neuromuscular Facilitation was added to the treatment of cases with moderate or severe facial dysfunctions. RESULTS: Benign and malignant groups had a statistically significant improvement in mS-FGS (p < 0.001 and p = 0.005, respectively). There was no significant difference between groups regarding treatment duration or number of physiotherapy sessions performed. The history of previous parotidectomy resulted in more severe initial dysfunctions and worse outcome. Age over 60 years and initially more severe dysfunctions impacted the outcome. CONCLUSION: Patients with benign and malignant parotid neoplasms had significant and equivalent improvement in postoperative facial dysfunction following an early tailored physiotherapy program, with no significant difference in the final facial score, treatment duration, or number of sessions required.

Study of the degradation in an ultisol of alginate-chitosan complex and its stability and applicability as a soil conditioner.

The present work describes the process of degradation of a polyelectrolytic complex (PEC) based on sodium alginate (ALG) and chitosan (CHI), buried for different time intervals, in a clayey soil (ultisol) collected from the municipality of Campos dos Goytacazes, in the northern region of the state of Rio de Janeiro, Brazil. The influence of PEC on soil moisture was also investigated. The results showed that soil moisture increased with the presence of PEC after 7 days of testing, and remained high until the end of the study. FTIR and Raman spectra showed that the breaking of the glycosidic bond (C-O-C) was responsible for the PEC degradation. Thermogravimetry results revealed that alginate was possibly degraded faster than chitosan. Microscopic analysis of the PEC revealed a fragile and fragmented surface of the samples that were buried, in comparison with those not buried. The microbiological assays of the soil confirmed the biodegradation of the polysaccharides. Chemical analysis of soil indicated that PEC did not significantly influence soil fertility. Therefore, we conclude that the PEC (ALG: CHI), formed only by electrostatic interaction, buried in clayey soil, even being biodegraded, can be a promising soil conditioner for agricultural applications.

Post-parotidectomy facial nerve function: comparison between original and modified Sunnybrook Facial Grading Systems.

BACKGROUND: Facial nerve dysfunction is the principal postoperative complication related to parotidectomy. OBJECTIVE: To test the hypothesis that the modified Sunnybrook Facial Grading System (mS-FGS) is superior to the original S-FGS in the assessment of facial nerve function following parotidectomy. METHODS: Prospective, longitudinal study evaluating patients with primary or metastatic parotid neoplasms undergoing parotidectomy with facial nerve-sparing between 2016 and 2020. The subjects were assessed twice, on the first postoperative day and at the first outpatient evaluation, 20-30 days post-surgery. Facial assessments were performed using the original and modified (plus showing the lower teeth) versions of the Sunnybrook System and documented by pictures and video recordings. Intra- and inter-rater agreements regarding the assessment of the new expression were analyzed. RESULTS: 101 patients were enrolled. In both steps, the results from the mS-FGS were significantly lower (p < 0.001). Subjects with a history of previous parotidectomy and those who underwent neck dissection had more severe facial nerve impairment. The mandibular marginal branch was the most frequently injured, affecting 68.3% of the patients on the first postoperative day and 52.5% on the first outpatient evaluation. Twenty patients (19.8%) presented an exclusive marginal mandibular branch lesion. The inter-rater agreement of the new expression assessment ranged from substantial to almost perfect. The intra-rater agreement was almost perfect (wk = 0.951). CONCLUSION: The adoption of the Modified Sunnybrook System, which includes evaluation of the mandibular marginal branch, increases the accuracy of post-parotidectomy facial nerve dysfunction appraisal.

ANTECEDENTES: A disfunção do nervo facial é a principal complicação pós-operatória relacionada à parotidectomia. OBJETIVO: Testar a hipótese de que o sistema Sunnybrook de graduação facial modificado (mS-FGS) é superior ao S-FGS original na avaliação da função do nervo facial após parotidectomia. MéTODOS:: Estudo longitudinal prospectivo avaliando o pós-operatório de pacientes com neoplasias parotídeas primárias ou metastáticas, submetidos à parotidectomia com preservação do nervo facial, entre 2016 e 2020. Os indivíduos foram avaliados duas vezes, no primeiro dia de pós-operatório e na primeira avaliação ambulatorial, 20-30 dias após a cirurgia. As avaliações faciais foram realizadas usando as versões original e modificada (que incluem mostrar os dentes inferiores) do sistema Sunnybrook e documentadas por fotos e vídeos. Foram adicionalmente analisadas as concordâncias intra e interexaminadoras da avaliação da nova expressão. RESULTADOS: Cento e um pacientes foram incluídos. Em ambas as etapas, os resultados do mS-FGS foram significativamente menores (p < 0,001). Indivíduos com história de parotidectomia prévia e aqueles submetidos ao esvaziamento cervical apresentaram comprometimento mais grave do nervo facial. O ramo marginal mandibular foi o mais afetado, acometendo 68,3% dos pacientes no primeiro dia de pós-operatório e 52,5% na primeira avaliação ambulatorial. Vinte pacientes (19,8%) apresentaram lesão exclusiva do ramo marginal mandibular. A concordância interexaminadores da avaliação da nova expressão variou de substancial a quase perfeita. A concordância intraexaminador foi quase perfeita (wk = 0,951). CONCLUSãO:: A adoção do sistema Sunnybrook modificado, que inclui a análise do ramo marginal mandibular, aumenta a precisão da avaliação da disfunção do nervo facial pós-parotidectomia.

Development of a cell-free screening assay for the identification of direct PERK activators.

The activation of the unfolded protein response, particularly via the PERK pathway, has been suggested as a promising therapeutic approach in tauopathies, a group of neurodegenerative disorders characterized by the abnormal phosphorylation and aggregation of tau protein. So far, a shortage of available direct PERK activators has been limiting the progresses in this field. Our study aimed at the development of a cell-free screening assay enabling the detection of novel direct PERK activators. By applying the catalytic domain of recombinant human PERK, we initially determined ideal conditions of the kinase assay reaction, including parameters such as optimal kinase concentration, temperature, and reaction time. Instead of using PERK's natural substrate proteins, eIF2α and NRF2, we applied SMAD3 as phosphorylation-accepting protein and successfully detected cell-free PERK activation and inhibition by selected modulators (e.g., calcineurin-B, GSK2606414). The developed assay revealed to be sufficiently stable and robust to assess an activating EC50-value. Additionally, our results suggested that PERK activation may take place independent of the active site which can be blocked by a kinase inhibitor. Finally, we confirmed the applicability of the assay by measuring PERK activation by MK-28, a recently described PERK activator. Overall, our data show that a cell-free luciferase-based assay with the recombinant human PERK kinase domain and SMAD3 as substrate protein is capable of detecting PERK activation, which enables to screen large compound libraries for direct PERK activators, in a high-throughput-based approach. These activators will be useful for deepening our understanding of the PERK signaling pathway, and may also lead to the identification of new therapeutic drug candidates for neurodegenerative tauopathies.

SECOND BRAZILIAN CONSENSUS ON THE MANAGEMENT OF ULCERATIVE COLITIS IN ADULTS: A CONSENSUS OF THE BRAZILIAN ORGANIZATION FOR CROHN'S DISEASE AND COLITIS (GEDIIB).

BACKGROUND: Inflammatory bowel diseases are immune-mediated disorders that include Crohn's disease (CD) and ulcerative colitis (UC). UC is a progressive disease that affects the colorectal mucosa causing debilitating symptoms leading to high morbidity and work disability. As a consequence of chronic colonic inflammation, UC is also associated with an increased risk of colorectal cancer. OBJECTIVE: This consensus aims to provide guidance on the most effective medical management of adult patients with UC. METHODS: A consensus statement was developed by stakeholders representing Brazilian gastroenterologists and colorectal surgeons (Brazilian Organization for Crohn's Disease and Colitis [GEDIIB]). A systematic review including the most recent evidence was conducted to support the recommendations and statements. All recommendations/statements were endorsed using a modified Delphi Panel by the stakeholders/experts in inflammatory bowel disease with at least 80% or greater consensus. RESULTS AND CONCLUSION: The medical recommendations (pharmacological and non-pharmacological) were mapped according to the stage of treatment and severity of the disease onto three domains: management and treatment (drug and surgical interventions), criteria for evaluating the effectiveness of medical treatment, and follow-up/patient monitoring after initial treatment. The consensus targeted general practitioners, gastroenterologists and surgeons who manage patients with UC, and supports decision-making processes by health insurance companies, regulatory agencies, health institutional leaders, and administrators.

SECOND BRAZILIAN CONSENSUS ON THE MANAGEMENT OF CROHN'S DISEASE IN ADULTS: A CONSENSUS OF THE BRAZILIAN ORGANIZATION FOR CROHN'S DISEASE AND COLITIS (GEDIIB).

BACKGROUND: Inflammatory bowel disease (IBD) is an immune-mediated disorder that includes Crohn's disease (CD) and ulcerative colitis. CD is characterized by a transmural intestinal involvement from the mouth to the anus with recurrent and remitting symptoms that can lead to progressive bowel damage and disability over time. OBJECTIVE: To guide the safest and effective medical treatments of adults with CD. METHODS: This consensus was developed by stakeholders representing Brazilian gastroenterologists and colorectal surgeons (Brazilian Organization for Crohn's disease and Colitis (GEDIIB)). A systematic review of the most recent evidence was conducted to support the recommendations/statements. All included recommendations and statements were endorsed in a modified Delphi panel by the stakeholders and experts in IBD with an agreement of at least 80% or greater consensus rate. RESULTS AND CONCLUSION: The medical recommendations (pharmacological and non-pharmacological interventions) were mapped according to the stage of treatment and severity of the disease in three domains: management and treatment (drug and surgical interventions), criteria for evaluating the effectiveness of medical treatment, and follow-up/patient monitoring after initial treatment. The consensus is targeted towards general practitioners, gastroenterologists, and surgeons interested in treating and managing adults with CD and supports the decision-making of health insurance companies, regulatory agencies, and health institutional leaders or administrators.

Influence of neoprene ankle orthoses on dynamic balance during a vertical jump in healthy individuals and with sprain history: A cross-sectional study.

INTRODUCTION: A sprain describes an excessive amount of force or strain on a ligament, which may or may not lead to its rupture. Orthoses are among the most common modalities prescribed as a conservative treatment for ankle instability and sprain. OBJECTIVE: We aimed to analyse the effect of neoprene orthosis on the balance and functionality of healthy individuals and volunteers with lateral ankle sprains METHODS: We evaluated 12 healthy volunteers (control group) and 12 volunteers diagnosed with a sprain and/or instability (patient group). A total of 14 men and 10 women participated in the study, with an average age of 26.15 (± 4.40) years. The volunteers' tasks consisted of performing vertical bipodal and unipodal jumps on a force platform, which were recorded in a video from the lateral view of the lower limb for posterior evaluation of the knee and ankle angles. Mann-Whitney and Wilcoxon tests were used for comparisons, considering p < 0.05 level of significance. RESULTS: The control group presented a decrease in ground reaction force when using Orthosis during the bipodal jump (p < 0.05). A decrease in anteroposterior force displacement was also observed in the left unipodal jump (p < 0.01). The patient group presented an increase in force and moment of medial-lateral displacement for both bipodal (p < 0.02) and left unipodal jumps with Orthosis (p < 0.02). A kinematic analysis showed that the control group presented the smallest knee flexion angle (p < 0.01), while the patient group presented the smallest dorsiflexion ankle angle in the bipodal jump when using orthosis (p < 0.01). CONCLUSION: We concluded that orthosis had influence on individuals' balance and joint angles. In healthy individuals presented better balance with and without orthosis and greater flexion with orthosis in the bipodal jump, regarding to the patient group presented smaller oscillations in the unipodal jump with orthosis and showed smaller knee flexion and ankle dorsiflexion.

Red LED light therapy associated with epidermal growth factor on wound repair process in rats.

Epidermal growth factor (EGF) and light-emitting diode (LED) are currently deployed as promissory treatments for skin repair; however, the mechanisms of their association are not yet evidenced. Thus, the present study aimed to evaluate the effects of combined treatment with EGF and red LED on the wound healing processes in rats. Adult Wistar rats were randomized in control group (CG) wounds without treatment; wounds submitted to EGF treatment (EGF); wounds submitted to LED treatment (LED); wounds submitted to EGF associated with LED treatments (EGF/LED). Treatments were performed immediately after the surgical procedure and each 24 h, totaling 8 sessions. Moreover, LED was applied before EGF treatment at a single point in the center of the wound. Morphological characteristics and the immunoexpression of COX-2, VEGF, and TGF-ß were measured. The results demonstrated that EGF/LED group presented a higher wound healing index. Additionally, all experimental groups presented similar findings in the histological evaluation, the degree of inflammation, and the area of dermis-like tissue. However, for EGF-treated animals (with or without LED), neoepithelial length was higher. Furthermore, all the treated groups decreased COX-2 and increased VEGF immunoexpression, and only EGF/LED group enhanced the TGF-ß protein expression when compared to the untreated group. This research shows that EGF and LED modulate inflammatory process and increase the vascularity. In addition, treatment of EGF associated with LED promoted a more evident positive effect for increasing TGF-ß expression and may be promising resources in the clinical treatment of cutaneous wounds.

Pesquisa IṢẸ́: contribuições da terapia ocupacional afrorreferenciada nos processos de formação e restituição das subjetividades negras / Pesquisa IṢẸ́: contributions of afro-referenced Occupational Therapy in the processes of formation and restitution of black subjectivities

Resumo Historicamente, na diáspora brasileira, a formação, as práticas profissionais e a produção de conhecimento pouco têm priorizado epistemologias, saberes e fazeres ancestrais negros, negligenciando direitos, singularidades e necessidades inerentes às pessoas negras. Estatisticamente configurada como maioria no Brasil, esta população deve ser alvo de ações políticas, acadêmicas e práticas que contemplem seus singulares modos de ser e estar no mundo, revertendo lógicas universais. Este manuscrito tem como objetivo apresentar de que forma a Pesquisa Iṣẹ́: construção de abordagens clínicas, culturais e educacionais voltadas para a população negra, vinculada ao Lab-Iṣẹ́/UFRJ, tem contribuído nos processos de formação e de restituição das subjetividades negras no Brasil. Caracteriza-se com um método de pesquisa qualitativa de abordagem cartográfica. A proposta é realizar a cartografia das bases teóricas e conceituais negras nas produções científicas, clínicas, culturais e educacionais nos cursos de graduação do país. Para este artigo, o recorte se deu para o curso de graduação em Terapia Ocupacional da UFRJ, mais especificamente no Lab-Iṣẹ́, por ser o primeiro Laboratório de Terapia Ocupacional do Brasil dedicado à temática da população negra. Além do levantamento e análise de materiais teóricos e documentais, as narrativas da equipe do laboratório possibilitaram considerar como resultado o quanto a terapia ocupacional afrorreferenciada tem sido uma importante construção condutora dos processos de formação e subjetivação das pessoas negras envolvidas nas ações do Laboratório. Espera-se que este trabalho inspire o campo para a reformulação de suas práticas embranquecidas.

Abstract Historically, in the Brazilian diaspora, training, professional practices, and the production of knowledge have not prioritized epistemologies, knowledge, and ancestral black practices, neglecting rights, singularities and needs inherent to black people. Statistically configured as the majority in Brazil, this population should be the target of political, academic, and practical actions that contemplate their unique ways of being in the world, reversing universal logics. This manuscript aims to present how the Iṣẹ́ Research: construction of clinical, cultural and educational approaches aimed at the black population, linked to the Lab-Iṣẹ́/UFRJ, has contributed to the processes of formation and restitution of black subjectivities in Brazil. The research method is qualitative with a cartographic approach. The proposal is to carry out the mapping of black theoretical and conceptual bases in scientific, clinical, cultural, and educational productions in undergraduate courses in the country. For this article, the focus was on the occupational therapy undergrad course at UFRJ, more specifically at Lab-Iṣẹ́, as it is the first occupational therapy laboratory in Brazil dedicated to the black population. In addition to the survey and analysis of theoretical and documentary materials, the narratives of the laboratory team made it possible to consider as a result how much afro-referenced occupational therapy has been an important construction leading to the processes of formation and subjectivation of black people involved in the actions of the Laboratory. It is hoped that this work will inspire the entire field for the reformulation of its whitened practices.

The database chosen for the selection of papers was PUBMED, using the following search strategy: "superior mesenteric artery syndrome"[title] AND (treatment[title] OR surgical[title]). Papers published between the years 2018 and 2023 were considered for review. Results: Initially, 13 papers were identified that met the previously established search strategy. After reading the titles and abstracts, 4 were excluded for not discussing the proposed theme, leaving 9 papers for review. Conclusion: The surgical modalities available for SMA treatment were considered safe, with low recurrence rates, and effective in symptom control and management of the syndrome.

As concepções de integralidade na saúde frente à pandemia da covid-19

Objetivo: Diante da complexa consolidação das concepções da integralidade no sistema de saúde, agravada pelos desafios conjunturais oriundos da pandemia, propomos analisar os impactos e desafios da implementação da integralidade no contexto da Covid-19. Método: trata-se de revisão narrativa a partir do levantamento de literatura das bases Medline e o Lilacs, adotando as palavras-chave "integralidade" e "saúde", e da análise de banco de dados do SUS (Datasus), de maneira a avaliar o impacto da pandemia nas concepções de integralidade na saúde. Resultados: a pandemia Covid-19 agravou ainda mais as fragilidades estruturais e os pontos de estrangulamento do SUS, notando-se redução da assistência médica aos usuários a nível ambulatorial e hospitalar, com um aumento expressivo de 2.538.59% no número de internações no subgrupo de "doenças virais" comparando 2019 e 2020, impactando na concepção organizacional do sistema. Na concepção holística, a integralidade durante o período de pandemia trouxe prejuízos econômicos e psicossociais a inúmeros brasileiros, com taxas de desemprego de aproximadamente 13% no ano de 2020. Conclusão: o contexto psicossocial e econômico ocasionados pela pandemia da Covid-19, fizeram com que profissionais de saúde se defrontassem com o desafio de garantir a atenção e cuidado integral aos indivíduos em meio a um cenário de morbimortalidade elevada e escassez de recursos. Diante disso, ações de saúde interdisciplinares, envolvendo diversos setores da sociedade civil, governos e comunidades, tornam-se essenciais para o enfrentamento da pandemia e para o fortalecimento do SUS.

Cytoreductive Surgical Treatment of Pleural Mesothelioma in a Porcine Model Using Magnetic-Resonance-Guided Focused Ultrasound Surgery (MRgFUS) and Radiofrequency Ablation (RFA).

A combination of surgery and chemotherapy is the most effective treatment available for Malignant Pleural Mesothelioma (MPM). However, both cause significant collateral damage and cannot eliminate residual microscopic disease. This investigation aimed to compare and determine the feasibility of utilizing Radiofrequency Ablation (RFA) and Magnetic-Resonance-guided Focused Ultrasound Surgery (MRgFUS) as alternative treatments for MPM. A large animal tumor model was developed in 13 Yorkshire female pigs using the MSTO211H cell line. Two pigs were initially used to determine the cyclosporine dose required for immunosuppression and tumor development. Subsequently, 11 other pigs underwent tumor development. Of these 11, 2 died during cell inoculation. Small tumor masses and adhesions were present in the other 9, indicating mesothelioma development. Five pigs then received RFA treatment, and 4 pigs received MRgFUS treatment. Tumor model development and effect of the two treatments were examined using MRI and by necropsy. RFA and MRgFUS both successfully ablated approximately the same sized area in the same treatment time. This study demonstrates that RFA and MRgFUS are feasible for tumor debulking, and while MRgFUS requires more pretreatment planning compared to RFA, MRgFUS is a completely noninvasive procedure.
