RESUMO
BACKGROUND: The predictive ability of the early determination of sex steroids and the total testosterone:estradiol ratio for the risk of severe coronavirus disease 2019 or the potential existence of a biological gradient in this relationship has not been evaluated. OBJECTIVES: To assess the relationship of sex steroid levels and the total testosterone:estradiol ratio with the risk of severe acute respiratory syndrome coronavirus 2 infection in men, defined as the need for intensive care unit admission or death, and the predictive ability of each biomarker. MATERIALS AND METHODS: This was a prospective observational study. We included all consecutive adult men with severe acute respiratory syndrome coronavirus 2 infections in a single center admitted to a general hospital ward or to the intensive care unit. Sex steroids were evaluated at the centralized laboratory of our hospital. RESULTS: We recruited 98 patients, 54 (55.1%) of whom developed severe coronavirus disease in 2019. Compared to patients with nonsevere coronavirus disease 2019, patients with severe coronavirus disease 2019 had significantly lower serum levels of total testosterone (111 ± 89 vs. 191 ± 143 ng/dL; p < 0.001), dehydroepiandrosterone (1.69 ± 1.26 vs. 2.96 ± 2.64 ng/mL; p < 0.001), and dehydroepiandrosterone sulfate (91.72 ± 76.20 vs. 134.28 ± 98.261 µg/dL; p = 0.009), significantly higher levels of estradiol (64.61 ± 59.35 vs. 33.78 ± 13.78 pg/mL; p = 0.001), and significantly lower total testosterone:estradiol ratio (0.28 ± 0.31 vs. 0.70 ± 0.75; p < 0.001). The lower the serum level of androgen and the lower the total testosterone:estradiol ratio values, the higher the likelihood of developing severe coronavirus disease 2019, with the linear trend in the adjusted analyses being statistically significant for all parameters except for androstenedione (p = 0.064). In the receiver operating characteristic analysis, better predictive performance was shown by the total testosterone:estradiol ratio, with an area under the curve of 0.77 (95% confidence interval 0.68-0.87; p < 0.001). DISCUSSION AND CONCLUSION: Our results suggest that men with severe acute respiratory syndrome coronavirus 2 infection, decreased androgen levels and increased estradiol levels have a higher likelihood of developing an unfavorable outcome. The total testosterone:estradiol ratio showed the best predictive ability.

BACKGROUND: CNS ganglioneuroblastoma in an extremely rare embryonal tumour, specifically in the pediatric population. Bad prognosis is documented due to aggressiveness and absence of protocolized treatment at the moment. CLINICAL DESCRIPTION: We present the case of a 5-year-old boy who presented with sudden loss of consciousness. CT scan was performed showing a large posterior fossa lesion with several intraventricular focal lesions, suggesting metastases, the largest one located inside the III ventricle. The patient underwent a posterior fossa resection of the lesion and a subtotal resection of the III ventricle lesion, with adjuvant chemotherapy. The evolution was poor and the patient finally died 3 months after diagnosis. CONCLUSION: Ganglioneuroblastoma is extremely likely to recur quickly and extensively. There is little knowledge about treatment options but is documented that gross total resection followed by adjuvant radiotherapy and chemotherapy is the best management in these patients.
RESUMO
Neuroblastoma is the most common extracranial solid tumor in infants, arising from developmentally stalled neural crest-derived cells. Driving tumor differentiation is a promising therapeutic approach for this devastating disease. Here, we show that the CDK4/6 inhibitor palbociclib not only inhibits proliferation but induces extensive neuronal differentiation of adrenergic neuroblastoma cells. Palbociclib-mediated differentiation is manifested by extensive phenotypic and transcriptional changes accompanied by the establishment of an epigenetic program driving expression of mature neuronal features. In vivo palbociclib significantly inhibits tumor growth in mouse neuroblastoma models. Furthermore, dual treatment with retinoic acid resets the oncogenic adrenergic core regulatory circuit of neuroblastoma cells, further suppresses proliferation, and can enhance differentiation, altering gene expression in ways that significantly correlate with improved patient survival. We therefore identify palbociclib as a therapeutic approach to dramatically enhance neuroblastoma differentiation efficacy that could be used in combination with retinoic acid to improve patient outcomes.

A hanseníase é uma doença crônica e infectocontagiosa causada pelo Mycobacterium leprae (M. leprae). Apresenta alta infectividade e baixa patogenicidade. O estudo teve como objetivo relatar a identificação de um paciente com hanseníase multibacilar através do teste sorológico (LID) em ação de busca ativa. Paciente do sexo masculino, 54 anos, residente em Governador Valadares, Minas Gerais, Brasil, proveniente da busca ativa do Núcleo de Pesquisa em Hansenologia (NuPqHans/UFJF-GV), apresentou teste sorológico positivo para proteínas recombinantes do bacilo (ML0405/ML2331). Encaminhado ao Centro de Referência de Doenças Endêmicas e Programas Especiais (CREDENPES), queixando-se de lesões na pele e nódulos pelo corpo, relatou histórico de traumas na cabeça, tonturas ocasionais, dormência nos pés e sangramento nasal. O paciente apresentou resultados de baciloscopia e biopsia positivos, concluindo o diagnóstico de hanseníase multibacilar, recebendo poliquimioterapia indicada. Após três meses de tratamento observou-se redução na área/diâmetro das lesões do abdômen, indicando a eficácia do tratamento. O resultado positivo do teste sorológico, permitiu a identificação de um paciente multibacilar, até então sem diagnóstico de hanseníase. Ademais, a utilização do teste sorológico LID nas atividades de busca ativa em áreas endêmicas para realização do diagnóstico precoce pode contribuir para o conceito zero hanseníase estipulado pela Organização Mundial da Saúde.

Leprosy is a chronic and infectious disease caused by Mycobacterium leprae (M. leprae). It has high infectivity and low pathogenicity. The aim of this study was to report the identification of a patient with multibacillary leprosy using the serological test (LID) during an active search. A 54-year-old male patient, living in Governador Valadares, Minas Gerais, Brazil, from the active search of the Leprosy Research Center (NuPqHans/UFJF-GV), presented a positive serological test for recombinant bacillus proteins (ML0405/ML2331). He was referred to the Reference Center for Endemic Diseases and Special Programs (CREDENPES), complaining of skin lesions and nodules all over his body, and reported a history of head trauma, occasional dizziness, numbness in his feet, and nosebleeds. The patient presented positive bacilloscopy and biopsy results, concluding the diagnosis of multibacillary leprosy and receiving the indicated multidrug therapy. After three months of treatment, there was a reduction in the area/diameter of the lesions on the abdomen, indicating the effectiveness of the treatment. The positive result of the serological test (LID) allowed the identification of a multibacillary patient, who until then had not been diagnosed with leprosy. In addition, the use of the LID serological test in active search activities in endemic areas for early diagnosis can contribute to the zero-leprosy concept stipulated by the World Health Organization.

RESUMO
INTRODUCTION/OBJECTIVES: Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by ongoing inflammation and degradation of synovial joints. The oral JAK inhibitor, upadacitinib, is approved for RA. We conducted an integrated safety analysis of upadacitinib 15 mg once daily (QD) in patients from Latin America (LATAM) versus the rest of the world (RoW). METHODS: Treatment-emergent adverse events (AEs) and laboratory data from six phase 3, randomized controlled trials, adjusted for upadacitinib 15 mg QD use in RA, were analyzed. RESULTS: Overall, 3209 patients received upadacitinib 15 mg QD for 7024 patient-years (PY). LATAM patients (n = 725) had a mean upadacitinib exposure of 1518 PY. Baseline characteristics were generally similar between LATAM and RoW populations. AE rates (including serious/opportunistic infections, tuberculosis, and herpes zoster) and deaths were comparable between populations. LATAM patients had lower serious AE rates per 100 PY (9.4 vs 14.0 E/100 PY) and discontinuation-related AEs (3.9 vs 6.0 E/100 PY) versus RoW. Rates of cardiovascular events were low (≤ 0.5 E/100 PY) and similar between populations. Malignancies, excluding non-melanoma skin cancer, were less common in the LATAM population versus RoW (0.2 vs 1.0 E/100 PY). Laboratory abnormalities were similar between populations, with decreases in hemoglobin, lymphocyte, and neutrophil counts, and elevations in liver enzymes and creatine phosphokinase. Mean change from baseline in low- and high-density lipoprotein cholesterol was generally comparable between LATAM and RoW populations. CONCLUSION: Upadacitinib 15 mg QD demonstrated a consistent safety profile across LATAM and RoW patient populations, with no new safety risks observed.

Ventriculo-gallbladder shunt is described as an effective alternative procedure in the treatment of hydrocephalus. We present the case of a 19-year-old patient diagnosed with suprasellar arachnoid cyst since his childhood and hydrocephalus, with a double shunt; ventriculo peritoneal and peritoneal cyst shunt. After several replacements due to peritoneal failure, he underwent ventriculoatrial shunt, with associated complications and subsequent repositioning to the peritoneum. After new valve dysfunction due to peritoneal complications, ventriculo-gallbladder shunt was proposed as an alternative treatment for this patient, which was safe and effective in resolving the patient's symptoms, and the patient was discharged, maintaining clinical stability in the follow-up more than 2 years later.

Neuroblastoma is believed to arise from sympathetic neuroblast precursors that fail to engage the neuronal differentiation programme, but instead become locked in a pro-proliferative developmental state. Achaete-scute homolog 1 (ASCL1) is a proneural master regulator of transcription which modulates both proliferation and differentiation of sympathetic neuroblast precursor cells during development, while its expression has been implicated in the maintenance of an oncogenic programme in MYCN-amplified neuroblastoma. However, the role of ASCL1 expression in neuroblastoma is not clear, especially as its levels vary considerably in different neuroblastoma cell lines. Here, we have investigated the role of ASCL1 in maintaining proliferation and controlling differentiation in both MYCN amplified and Anaplastic Lymphoma Kinase (ALK)-driven neuroblastoma cells. Using CRISPR deletion, we generated neuroblastoma cell lines lacking ASCL1 expression, and these grew more slowly than parental cells, indicating that ASCL1 contributes to rapid proliferation of MYCN amplified and non-amplified neuroblastoma cells. Genome-wide analysis after ASCL1 deletion revealed reduced expression of genes associated with neuronal differentiation, while chromatin accessibility at regulatory regions associated with differentiation genes was also attenuated by ASCL1 knock-out. In neuroblastoma, ASCL1 has been described as part of a core regulatory circuit of developmental regulators whose high expression is maintained by mutual cross-activation of a network of super enhancers and is further augmented by the activity of MYC/MYCN. Surprisingly, ASCL1 deletion had little effect on the transcription of CRC gene transcripts in these neuroblastoma cell lines, but the ability of MYC/MYCN and CRC component proteins, PHOX2B and GATA3, to bind to chromatin was compromised. Taken together, our results demonstrate several roles for endogenous ASCL1 in neuroblastoma cells: maintaining a highly proliferative phenotype, regulating DNA binding of the core regulatory circuit genes to chromatin, while also controlling accessibility and transcription of differentiation targets. Thus, we propose a model where ASCL1, a key developmental regulator of sympathetic neurogenesis, plays a pivotal role in maintaining proliferation while simultaneously priming cells for differentiation in neuroblastoma.
RESUMO
BACKGROUND: The pro-neural transcription factor ASCL1 is a master regulator of neurogenesis and a key factor necessary for the reprogramming of permissive cell types to neurons. Endogenously, ASCL1 expression is often associated with neuroblast stem-ness. Moreover, ASCL1-mediated reprogramming of fibroblasts to differentiated neurons is commonly achieved using artificially high levels of ASCL1 protein, where ASCL1 acts as an "on-target" pioneer factor. However, the genome-wide effects of enhancing ASCL1 activity in a permissive neurogenic environment has not been thoroughly investigated. Here, we overexpressed ASCL1 in the neuronally-permissive context of neuroblastoma (NB) cells where modest endogenous ASCL1 supports the neuroblast programme. RESULTS: Increasing ASCL1 in neuroblastoma cells both enhances binding at existing ASCL1 sites and also leads to creation of numerous additional, lower affinity binding sites. These extensive genome-wide changes in ASCL1 binding result in significant reprogramming of the NB transcriptome, redirecting it from a proliferative neuroblastic state towards one favouring neuronal differentiation. Mechanistically, ASCL1-mediated cell cycle exit and differentiation can be increased further by preventing its multi-site phosphorylation, which is associated with additional changes in genome-wide binding and gene activation profiles. CONCLUSIONS: Our findings show that enhancing ASCL1 activity in a neurogenic environment both increases binding at endogenous ASCL1 sites and also results in additional binding to new low affinity sites that favours neuronal differentiation over the proliferating neuroblast programme supported by the endogenous protein. These findings have important implications for controlling processes of neurogenesis in cancer and cellular reprogramming.

Introdução: A associação de leucemia linfocítica crônica (LLC) e melanoma tem sido estudada nos últimos anos. Acredita-se que a imunossupressão causada pelo tratamento da doença seja o fator de risco mais importante para o aumento da susceptibilidade ao desenvolvimento e disseminação do câncer de pele. Relato de Caso: Este relato de caso descreve homem de 53 anos, em tratamento de leucemia linfocítica crônica desde 2018, já submetido a diversos ciclos de quimioterapia com fludarabina. Apresentou histórico de exérese de melanoma nodular epitelioide no couro cabeludo em 2019, removido com margens livres. Um ano após a cirurgia, paciente evoluiu com piora do estado geral com necessidade de hospitalização. Investigação adicional revelou focos de metástase em pulmões, fígado, rins, estômago, sistema nervoso central e linfonodos. Análise histopatológica foi positiva para melanoma. A possibilidade de tratamento foi descartada pela equipe de oncologia, que sugeriu cuidados paliativos. Discussão: Um dos mecanismos mais discutidos para explicar esta associação de neoplasias é a imunossupressão resultante do tratamento da LLC, que deixa o paciente suscetível ao desenvolvimento e à disseminação do melanoma. Além disso, a fludarabina, quimioterápico geralmente usado para remissão da LLC, é conhecida por depletar células T-helper e tem sido descrita como cofator deste processo. A associação de leucemia e melanoma cutâneo têm sido descrita nos últimos anos, porém não há nenhum protocolo de tratamento para esta condição.
BACKGROUND: The association of Chronic Lymphocytic Leukemia (CLL) and melanoma have been studied in the last years. The immunosuppression caused by the treatment of CLL seems to be the major factor of increasing patients' susceptibility to the development and spread of skin cancer. CASE REPORT: This case report describes a 53-year-old male patient, in CLL treatment since 2018, already submitted to many cycles of chemotherapy with fludarabine. History of an exeresis of epithelioid nodular melanoma of the scalp in 2019, which was removed with a clear margin. One year later, he presented with a poor general condition with hospitalization indication. Additional investigation revealed metastatic lesions in lungs, liver, kidneys, stomach, central nervous system, and lymph nodes. Histopathologic analysis positive for melanoma. The possibility of treatment was discarded by the Oncology team, which suggested palliative care. DISCUSSION: One of the most discussed mechanisms to explain this cancer association is the immunosuppression developed during the treatment of CLL, increasing patients' susceptibility to the development and spread of melanoma. In addition, the use of fludarabine, a chemotherapy commonly used in relapsed CLL, is known to deplete T-helper cells and has been described as a cofactor of this process. The association of leukemia and cutaneous melanoma has been reported in the last years, yet there is no surveillance protocol.

Pediatric cancers often resemble trapped developmental intermediate states that fail to engage the normal differentiation program, typified by high-risk neuroblastoma arising from the developing sympathetic nervous system. Neuroblastoma cells resemble arrested neuroblasts trapped by a stable but aberrant epigenetic program controlled by sustained expression of a core transcriptional circuit of developmental regulators in conjunction with elevated MYCN or MYC (MYC). The transcription factor ASCL1 is a key master regulator in neuroblastoma and has oncogenic and tumor-suppressive activities in several other tumor types. Using functional mutational approaches, we find that preventing CDK-dependent phosphorylation of ASCL1 in neuroblastoma cells drives coordinated suppression of the MYC-driven core circuit supporting neuroblast identity and proliferation, while simultaneously activating an enduring gene program driving mitotic exit and neuronal differentiation. IMPLICATIONS: These findings indicate that targeting phosphorylation of ASCL1 may offer a new approach to development of differentiation therapies in neuroblastoma.

Hereditary Angioedema (HEA), a disease caused by a mutation in the gene that encodes for the production of the fraction C1 in the complement (C1-INH), is a rare pathology (1/50.000) that causes swelling of the skin and submucosa in various organs, either naturally triggered or provoked by physical and psychological traumas, infections, or by the use of nonsteroidal anti-inflammatory drugs (NSAIDs) and angiotensin-converting enzyme inhibitors (ACEIs). Surgical trauma may spur the HEA crisis, leading to complications such as the swelling of the respiratory tracts and hemodynamic instability. Thus, the pre-surgical approach to HEA patients requires a specific plan that ensures short term prophylaxis, careful intra-operative management, rescue therapy and intensive post-surgery care. We present a report on a video-laparoscopic cholecystectomy approach for a 28-year-old woman diagnosed with asthma and HEA with symptomatic choledocholithiasis. We opted for short-term prophylaxis and immunology with the intravenous application of C1-INH. Ultrasonography imaging showed arterial wall oedema, which could correspond to a manifestation of C1-INH deficiency in the wall of the manipulated arteries during ultrasonography-guided puncture. Once the patient recovered consciousness, she was transferred to the intensive care unit and was discharged on the 6th day of hospitalisation.
RESUMO
Objetivo: investigar a resistência de união por cisalhamento de diferentes soluções contendo silano e primer na superfície de Dissilicato de Lítio (IPS e.maxCAD, Ivoclar-Vivadent). Metodologia: 78 blocos cerâmicos foram incluídos em resina acrílica, polidos e lavados em ultra-som por 10 minutos. Os espécimes foram divididos em dois grupos de acordo com tratamento de superfície: Superfície Polida (PS); Ácido Hidro-Fluorídrico 9,5% - 20s (HF). Cada grupo foi dividido em três subgrupos (n = 13), de acordo com o tipo de silano: silano tradicional (Porcelain Prime, Inc. Bisco); mistura de silano e resina (KerrSilane, Kerr); mistura de silano e adesivo universal (Single-bond Universal, 3M Espe). Os espécimes foram montados em um dispositivo padrão para teste de cisalhamento (UltradentBonding Assembly), cimentados com cimento resinoso dual (Duolink Universal™, Bisco Inc.) e foto-polimerizados por 20s. As amostras foram testadas após 24 horas e 90 dias de armazenamento em água destilada a 47°C. Os dados foram analisados por 2-Way Anova e Teste de Tukey (α=5%). Resultados: em geral, os valores de resistência adesiva do silano tradicional foram, estatisticamente, mais elevados do que os outros tipos de silanos. O armazenamento afetou, significativamente, a força de adesão para a maioria dos grupos (p <0,001). O grupo PS apresentou menores valores de resistência adesiva, independentemente da variável (silano vs armazenamento). Conclusões: adequada resistência adesiva pode ser obtida com silanos tradicionais após o pré-tratamento de superfície com ácido HF
Objective: To investigate the efficacy of "new silanes / primer" in the Lithium Disilicate surface (IPS e.maxCAD, IvoclarVivadent-) by means of adhesive shear bond strength test. Methodology: A total of 78 ceramic blocks were embedded in acrylic resin, polished and washed in ultrasound for 10 minutes. The specimens were divided into two groups according to surface treatment: Polished Surface (PS); Hydrofluoric acid 9,5% - 20s (HF). Each group was divided into three sub-groups (n = 13) according to the type of silane used: traditional silane (Porcelain Prime Bisco, Inc.); mixture of silane and resin (Kerr Silane, Kerr); mixture of silane and universal adhesive (Single-bond Universal, 3M Espe). The specimens were mounted on a standard device for shear test (Ultradent Bonding Assembly), cemented with dual resin cement (Duolink Universal ™, Bisco Inc.) and photo-polymerised for 20s. The samples were tested after 24 hours and 90 days of storage in distilled water at 47°C. Data were analyzed by 2-way ANOVA and Tukey Test (α = 5%). Results: In general, the adhesive strength value of traditional silanewas significantly higher than other types of silanes. The storage significantly affects the bond strength (bond) for most groups (p <0.001). The PS group showed lower bond strength values, independent of the variable (silane vs. storage). Conclusions: Suitable adhesive strength can be obtained with traditional silanes, combined with the pre-treatment surface with HF acid.
