Abstract Objective Endometrial cancer (EC) is a heterogeneous disease with recurrence rates ranging from 15 to 20%. The discrimination of cases with a worse prognosis aims, in part, to reduce the length of surgical staging in cases with a better prognosis. This study aimed to evaluate the association between Insulin-like growth factor II mRNA-binding protein 3 (IMP3) expression and prognostic and morphological factors in EC. Methods This retrospective, cross-sectional, analytical study included 79 EC patients - 70 endometrioid carcinoma (EEC) and 9 serous carcinoma (SC) - and 74 benign endometrium controls. IMP3 expression was evaluated by immunohistochemistry-based TMA (Tissue Microarray), and the results were associated with morphological and prognostic factors, including claudins 3 and 4, estrogen and progesterone receptors, TP53, and KI67. Results IMP3 expression was significantly higher in SC compared to EEC in both extent (p<0.001) and intensity (p=0.044). It was also significantly associated with worse prognostic factors, including degree of differentiation (p=0.024, p<0.001), staging (p<0.001; p<0.001) and metastasis (p=0.002; p<0.001). IMP3 expression was also significant in extent (p=0.002) in endometrial tumors compared with controls. In addition, protein TP53 and KI67 showed significant associations in extent and intensity, respectively. Conclusion IMP3 expression was associated with worse prognostic factors studied. These findings suggest that IMP3 may be a potential biomarker for EC poorer prognosis.

A evasão é um tema de interesse mundial na área da educação, contudo o entendimento atual sobre o fenômeno é ainda insuficiente, sobretudo quando o objetivo é avaliar políticas efetivas de evasão. Neste artigo o percentual anual de evasão da Unesp é avaliado com base na adoção da política de reserva de vagas. Existem três possibilidades de ingresso - sistema universal (SU), quota por ter estudado em escola pública (EP) e quota por ser PPI (pretos, pardos, indígenas). Os dados foram segmentados por curso e ano de ingresso. A Unesp tem campus em 24 cidades, que reúnem 34 unidades e abrigam 136 diferentes cursos de Graduação. O ingresso para estes cursos é realizado por meio de vestibular com 186 diferentes opções em 63 carreiras. Uma comparação das taxas de evasão permite observar que elas podem depender do modo de ingresso, mas isso ocorre de forma variada ao longo do tempo e depende da área do curso, não sendo significativo. Verificou-se um decréscimo consistente da taxa de evasão global e por categoria de ingresso.

Student dropout is a topic of worldwide interest in the field of education research; however, current understanding of the phenomenon remains insufficient, particularly when the objective is to evaluate effective retention policies. The annual dropout rate at UNESP was evaluated based on the admission selection policy. There are three admission categories: the universal exam system; a selection quota for students who studied in public schools; and a selection quota for students who are Black, Brown or Indigenous. The data was classified by course and admittance year. UNESP has campuses in 24 towns, divided into 34 campuses that provide 136 different undergraduate courses. Admission to these courses is conducted by an entrance exam with 186 different options in 63 careers. A comparison of dropout rates shows that these may depend on the admission category, but it varies over time and depends on the course subject. The data also reveal a consistent decrease in the annual dropout rates, according to the admission category.

▪ ABSTRACT Introduction: Aiming to obtain autogenous and injectable lipografts from resected tissues in dermolipectomies, this study proposes a new method for harvesting and processing adipose tissue through a specific fragmenting device. The main objective was to establish a comparative analysis of the quality and viability characteristics of the new lipofragmentation technique and those of the well-known liposuction technique, widely accepted as a viable source of fat grafting. In vivo and in vitro assays were designed to evaluate the biological behavior of the samples to guide new and possible human studies with clinical applications. Methods: A post-bariatric patient who underwent abdominal dermolipectomy had her surgical specimen resected, which was divided into four parts that underwent liposuction and lipofragmentation, with and without prior infiltration. All samples were centrifuged and distributed for assays with assessments involving histological analysis, immunohistochemistry, flow cytometry, cell culture, and xenograft injection on the back of 10 Wistar rats, which was evaluated after six weeks for mass, volume, and histological features. Results: The structural characteristics and biological behaviors of fragmented, dry, and infiltrated fat samples were similar to those of liposuction samples. Conclusions: Fat fragmentation transformed the subcutaneous cellular tissue of dermolipectomies into a new, viable injectable lipograft variant, with biological characteristics similar to those of traditional liposuction. Although still preliminary, our results support further investigations to optimize the technique and improve fat grafting and its possible applications in regenerative medicine.

▪ RESUMO Introdução: Com o objetivo de obter lipoenxerto autógeno e injetável de tecido ressecado em dermolipectomias, este estudo propõe um novo método para colheita e processamento do tecido adiposo, através de um dispositivo fragmentador específico. O principal objetivo foi estabelecer uma análise comparativa das características de qualidade e viabilidade do novo lipofragmentado em relação ao já conhecido lipoaspirado, amplamente aceito como fonte viável de lipoenxerto. Ensaios in vivo e in vitro foram delineados para avaliar o comportamento biológico das amostras, a fim de orientar novos e possíveis estudos em humanos com aplicações clínicas. Métodos: Uma paciente pós-bariátrica que foi submetida a dermolipectomia abdominal teve sua peça cirúrgica ressecada e dividida em quatro partes que foram submetidas a Lipoaspiração e Lipofragmentação, sem e com infiltração prévia. Todas as amostras foram submetidas a centrifugação e então distribuídas para os ensaios que envolveram avaliação histológica, imunohistoquímica, citometria de fluxo, cultura celular e ainda a injeção de xenoenxerto no dorso de 10 ratos Wistar, retirados após seis semanas para avaliação de massa, volume e características histológicas. Resultados: As amostras de gordura fragmentada, seca e infiltrada, mostraram características estruturais e comportamento biológico semelhantes aos das amostras de lipoaspirado. Conclusões: A fragmentação da gordura transformou o tecido celular subcutâneo das dermolipectomias em uma nova variante de lipoenxerto injetável e viável, com características biológicas semelhantes àquelas do lipoaspirado tradicional. Embora ainda preliminares, nossos resultados embasam a realização de novas investigações buscando otimizar a técnica com vistas ao aprimoramento da enxertia gordurosa e suas possíveis aplicações na medicina regenerativa.

Abstract Purpose To assess Cyclosporine A (CsA) therapy at an intraperitoneal dose of 15 mg.kg -1 in a rodent model of non-septic renal ischemia. Methods Twenty male Wistar rats were randomized to receive CsA therapy or none therapy before undergoing 30 minutes of renal ischemia followed by reperfusion. Additionally, 10 rats were randomized to undergo the same surgical procedure of the aforementioned animals with neither ischemia nor CsA therapy. Twelve hours after kidney ischemia, the left kidneys were evaluated for histological injury according to Park’s criteria. Serum creatinine (Cr), urea nitrogen (Ur) and sodium levels were obtained at different times of the experimental protocol. Results Rodents in the CsA group showed negative results (p<0.05) in serum variables (Cr: 0.41±0.05mg/dL vs . 4.17±1.25mg/dL; Ur: 40.90±3.98mg/dL vs . 187.70±22.93mg/dL) even the non CsA or control group (Cr: 0.35±0.07mg/dL vs . 3.80±1.20mg/dL; Ur: 40.10±4.70mg/dL vs . 184.50±49.80mg/dL). The negative results were also verified in histological evaluation, CsA group had 50% in the very severe grade of lesion, 10% in the severe and 40% in the moderate to severe whereas the control group had 90% in the very severe grade. Conclusion CsA was incapable of preventing the deleterious effects of ischemia-reperfusion injury in rat kidneys.

PURPOSE: To evaluate the effect of parecoxib (an NSAID) on renal function by measuring plasma NGAL (serum neutrophil gelatinase-associated lipocalin) levels in an induced-ischemia rat model.METHODS: Forty male Wistar rats were randomly assigned to one of four groups: Ischemia (I), Ischemia/parecoxib (IP), No-ischemia (NI), and No-ischemia/parecoxib (NIP). Body weight, mean arterial pressure, heart rate, body temperature, NGAL levels, and renal histology were compared across groups.RESULTS: The Ischemia (I) group, which did not receive parecoxib, showed the highest NGAL levels (p=0.001), while the IP group, which received the medication, had NGAL levels similar to those of the non-ischemic (NI and NIP) groups.CONCLUSION:Parecoxib resulted in renal protection in this experimental model.

PURPOSE: To investigate the effects of exposure to cigarette and alcohol on immunohistochemical disorders caused by these attacks to respiratory system of rats.METHODS:Sixty male Wistar rats in four groups: control, cigarette smoke, alcohol and cigarette smoke + alcohol during 260 days. Immunohistochemistry was performed by researching survivin and protein P53 expressions and apoptotic index in parenchymal lung and trachea using TUNEL technique.RESULTS: There was body growth impairment in all experimental groups. Both smoker groups animals had higher trachea survivin expression and bronchial higher apoptotic index. The trachea apoptotic index was also higher in the cigarette smoke group as well as in the alveoli in the cigarette smoke + alcohol group. The three experimental groups showed negative immunoexpression for P53.CONCLUSIONS: this model resulted in immunohistochemical changes caused mainly by exposure to cigarette smoke. There was a synergistic action between alcohol and tobacco in the growth impairment in animals as well as in the cellular apoptotic index. The positive immunoexpression for tracheal survivin in animals from both groups exposed to tobacco smoke and associated with a negative P53 immunoexpression suggests that despite the aggression, carcinogenesis has not happened yet. In addition, the bronchial higher apoptotic index in smokers may be responsible for emphysema.

PURPOSE:To investigate whether allopurinol exerts a protective effect on kidneys by measuring new kidney injury biomarkers (NGALp, NGALu, KIM 1 and IL 18) and analysing the renal function and histology in uninephrectomised rats subjected to ischaemia-reperfusion injury.METHODS: Thirty two Wistar rats were randomly allocated to four groups: Sham (S): laparotomy; Control (C): laparotomy and ischaemia-reperfusion in the left kidney; Control Allopurinol (CA): laparotomy and allopurinol at a dose of 100mg·kg1·d 1; and Allopurinol (A): laparotomy ischaemia-reperfusion in the left kidney and allopurinol at a dose of 100mg·kg 1·d1. The NGALp, NGALu, KIM 1, IL 18 and creatinine levels and the kidney histology were analysed. The significance level was established as p<0.05.RESULTS:Creatinine level increased in all the groups, with A ≈ C > S ≈ CA. The NGALp, NGALu and IL 18 levels exhibited similar behaviour in all the groups. KIM 1 was higher in group A than C and showed intermediate values in groups S and CA. Severity of injury in the left kidney was greater in groups C and A compared to S and CA.CONCLUSION:Allopurinol did not exert protective or damaging effects on the kidneys of rats subjected to ischaemia-reperfusion injury.

PURPOSE: To investigate and compare the biocompatibility of two types of Ferrara intracorneal ring segment: with and without chondroitin sulfate coating by clinical and histopathological evaluation. METHODS: A randomized experimental study was carried out on thirty right-eye corneas from 30 Norfolk albino rabbits allocated into two experimental groups: Group G1 - implanted with Ferrara intracorneal ring segment without coating (FICRS) and Group G2 - implanted with Ferrara intracorneal ring segment with chondroitin sulfate coating (FICRS-CS). Left eyes formed the control group. Clinical parameters analyzed were: presence of edema, vascularization, infection and ring extrusion one, 30, and 60 days after surgery. Histopathological parameters analyzed were: number of corneal epithelial layers over and adjacent to the ring, presence of spongiosis, hydropic degeneration, basement membrane thinning, inflammatory cells, neovascularization and pseudocapsule formation. RESULTS: At clinical examination 60 days after implant, edema, vascularization and extrusion were observed respectively in 20%, 26.7%, 6.7% of FICRS corneas and in 6.7%, 6.7%, and 0% of FICRS-CS corneas. Histopathological evaluation showed epithelial-layer reduction from 5 (5;6) to 3 (3;3) with FICRS and from 5 (5;5) to 4 (3;5) with FICRS-CS in the region over the ring. Epithelial spongiosis, hydropic degeneration, and basement membrane thinning were present in 69.2%, 53.8%, and 69.2% of FICRS and in 73.3%, 73.3%, and 46.7% with FICRS-CS, respectively. Vascularization was present in 38.5% of FICRS and 13.3% with FICRS-CS, inflammatory cells in 75% of FICRS and 33.3% with FICRS-CS, and pseudocapsule in 66.7% of FICRS and 93.3% with FICRS-CS. Giant cells occurred only in the FICRS-CS group (20%). CONCLUSION: Ferrara intracorneal rings coated with chondroitin sulfate (FICRS-CS) caused lower frequency of clinical and histopathological alterations than Ferrara intracorneal rings without the coating (FICRS), demonstrating higher biocompatibility of the FICRS-CS.

PURPOSE: To compare fluid replacement therapy with Hydroxyethyl starch 6% (HES) versus Ringer's lactate (RL) in a rodent model of non-septic renal ischemia. METHODS: Forty male Wistar rats were randomized to receive HES 2 ml.kg-1.hr-1or RL 5 ml. kg-1.hr-1 that underwent 30 minutes of renal ischemia followed by reperfusion. Twelve hours after kidney ischemia, the kidneys were evaluated for histological changes. Serum NGAL levels were obtained at different times of the experimental protocol. RESULTS: Rodents in the HES group had a median (IQR) grade of renal injury 3 (3 to 5) compared to 2 (2 to 4) in the RL group (p=0.03). NGAL levels were not associated with the severity of kidney injury. CONCLUSION: Hydroxyethyl starch administration caused more kidney injury than Ringer's lactate in a non-infectious model of renal hypoperfusion.

A hemofagocitose reativa ou síndrome de ativação macrofágica (SAM) é uma complicação das doenças inflamatórias sistêmicas, causada por expansão de células T e macrófagos, com produção maciça de citocinas pró-inflamatórias, ocorrendo mais freqüentemente na artrite idiopática juvenil sistêmica e raramente no lúpus eritematoso sistêmico juvenil (LESJ). OBJETIVO: Relatar um caso de LESJ que evoluiu com SAM precipitada por infecção e infarto esplênico, com desfecho fatal. RELATO DE CASO: Uma menina de 7 anos, com diagnóstico de LESJ desde os 5 anos, evoluiu com artrite em atividade, alopecia intensa, citopenias, cefaléia, infecções respiratórias recorrentes e elevação intermitente de transaminases. Os anticorpos anti-DNA e anticardiolipina IgG e IgM foram identificados e a biópsia renal evidenciou glomerulonefrite lúpica de classe III. A paciente foi tratada com pulso de metilprednisolona, prednisona, azatioprina e hidroxicloroquina. Após dois anos, na vigência de pneumonia apresentou abdome agudo e convulsões, evoluindo para o choque hemorrágico fatal após esplenectomia, que evidenciou infarto esplênico e infiltração maciça por macrófagos hemofagocíticos CD163+. CONCLUSÃO: A revisão do desfecho sugere a SAM precipitada por infecção e sobreposta a atividade inflamatória do lúpus com febre persistente, citopenias, disfunção hepática, hepatomegalia e esplenomegalia, como efeitos do excesso de produção de citocinas. Os anticorpos anticardiolipina podem ter tido papel precipitante na coagulopatia, que resultou infarto esplênico e choque hemorrágico.

Reactive haemophagocytosis or macrophage activation syndrome (MAS) is a complication of systemic inflammatory disorders, caused by expansion of T cells and haemophagocytic macrophages, with cytokine overproduction. It has been described most often in systemic juvenile idiopathic arthritis and rarely in juvenile systemic lupus erythematosus (JSLE). OBJECTIVE: To report a JSLE case who developed MAS in association with spleen infarct triggered by infection, with fatal outcome. CASE REPORT: A 7-year old-girl diagnosed with lupus since age 5-y developed several episodes of arthritis flare, cytopenias, severe alopecia, headaches and recurrent episodes of respiratory infections with intermittently increased serum transaminases. Anti-DNA and anti-cardiolipin IgG and IgM were identified and Class III lupus glomerulonephritis was diagnosed by renal biopsy. The patient was treated with methylprednisolone pulses, prednisone, azatioprine and hydroxychloroquine. Last admitted due to pneumonia, she evolved into abdominal crisis and seizures, undergoing splenectomy and evolving into haemorragic shock with fatal outcome. A spleen infarct was found and anti-CD163 antibodies staining disclosed intense haemophagocytic macrophage infiltration. CONCLUSION: This outcome suggests infection-triggered MAS overlapping lupus flare with persistent fever, cytopenia, liver dysfunction, hepatomegaly and splenomegaly as cytokine excess driven effect. Anti-cardiolipin antibodies may also had a coagulopathy precipiting role.
