Intensive salvage chemotherapy with VDTPACE or mCBAD followed by hematopoietic stem-cell support for refractory/relapsed multiple myeloma.

INTRODUCTION: Triple- and quad-refractory multiple myeloma patients usually have an aggressive course and a poor prognosis. Available therapeutic options are scarce. METHODS: The objective of the current study was to evaluate responses and toxicities of VDTPACE or mCBAD with hematopoietic stem-cell support as a bridge to subsequent therapies in patients with refractory/relapsed multiple myeloma. RESULTS: Thirteen patients were included (11 mCBAD, 2 VDTPACE), and 21 cycles of chemotherapy with hematopoietic stem-cell support were delivered. Mean number of previous therapies was 4.8. Stem cells were infused on a median day 9.9 after chemotherapy. Mean time to neutrophil recovery was 18.2 days in patients receiving the first cycle and 15.9 following subsequent cycles. Before therapy, most patients were in PD (77%), PR (15%), or VGPR (8%). Following treatment, the best responses achieved were PR (46%), VGPR (46%), and CR (8%). Median overall and progression-free survivals were 17 and 9 months. There has been no case of non-relapse mortality. In the 21 cycles, the main complications were infectious. CONCLUSION: Intensive chemotherapy can decrease disease burden in patients with relapsed/refractory MM, and stem-cell support can successfully decrease toxicities and treatment-related mortality associated with these regimens and may be a good bridging option.

Molecular profile of patients with myelofibrosis: a 10-year experience.

OBJECTIVE: To analyze the karyotype test and myeloid panel with next-generation sequencing findings in patients with myelofibrosis, and to compare transplant characteristics in patients referred for bone marrow transplantation. METHODS: Retrospective, single-center study with patients diagnosed with myelofibrosis treated at Hospital Israelita Albert Einstein between 2010 and 2020. RESULTS: A total of 104 patients with myelofibrosis were examined. Patients who had not been submitted to tests in our service were excluded. The final sample comprised 69 patients. Of these 69, 56 were submitted to karyotyping and 22 to myeloid panel with next-generation sequencing. Karyotype was normal in 60% of the patients and altered in 40%. The prevalence of high-risk molecular mutations was higher in patients referred for bone marrow transplantation (100% versus 50%). The median follow-up of transplant patients was 2.4 years and the overall survival at 2 years was 80% (95%CI: 62-100%). CONCLUSION: The molecular analysis enables estimating the patient's risk and thus instituting more aggressive treatment such as bone marrow transplant for patients at higher risk, being a relevant tool to guide therapy. Given the significance of molecular analysis for therapeutic decision-making in myelofibrosis, collection and disclosure of data on the prevalence of cytogenetic changes and findings of next-generation sequencing in affected patients is important.

Patulin in tomatoes and the inhibitory capacity of their phenolic extracts against Penicillium expansum.

This study aimed to determine Patulin (PAT) in samples of organically and conventionally grown tomato varieties, to correlate it with their phenolic profile and at evaluating effects of phenolic extracts of tomato samples against the Penicillium expansum CCT 7549 strain. Four varieties of tomatoes (Cherry, Khaki, Italian and Long Life) subject to conventional and organic management were collected in markets in the south of Brazil. PAT was determined in samples by validated method Matrix Solid Phase Dispersion (MSPD) with detection in HPLC-PDA. Titratable acidity, phenolic profile and antifungal activity (minimum inhibitory concentration - MIC and minimum fungicidal concentration - MFC) against P. expansum were determined. In most tomatoes PAT was found at levels that were below the Maximum Recommended Level (MRL = 50 µg/kg). Samples of conventionally grown Cherry tomato showed high acidity and PAT contamination, whose correlation was confirmed by the Principal Component Analysis (PCA). Phenolic extracts of tomatoes subject to conventional management were more efficient to inhibit P. expansum, a fact that may be explained by the content of caffeic acid. However, since PAT production was not inhibited in fruit, it is recommended that PAT should be monitored and a new management strategy should be investigated.

A simple quinoline salt derivative is active in vitro against Plasmodiumfalciparum asexual blood stages and inhibits the development of cerebral malaria in murine model.

Chloroquine (CQ) was the most effective and widely used drug for the prophylaxis and treatment of severe and non-severe malaria. Although its prophylactic use has led to resistance to P. falciparum in all endemic countries, CQ still remains the drug of choice for the treatment of vivax malaria. Otherwise, the speed in which parasite resistance to available antimalarials rises and spreads in endemic regions points to the urgent need for the development of new antimalarials. Quinoline derivatives have been used as a tool in the search for new drugs and were investigated in the present study in an attempt to produce a HIT compound to avoid the cerebral malarial (CM). Seven compounds were synthesized, including three quinoline derivate salts. The cytotoxicity and antiplasmodial activity were assayed in vitro, highlighting compound 3 as a HIT, which also showed interaction with ferriprotoporphyrin IX similarly to CQ. Physicochemical and pharmacokinetic properties of absorption were found to be favorable when analyzed in silico. The in vivo assays, using the experimental cerebral malaria (ECM) model, showed important values of parasite growth inhibition on the 7th day-post infection (Q15 15 mg/kg: 76.9%, Q30 30 mg/kg: 90,1% and Q50 50 mg/kg: 92,9%). Compound 3 also showed significant protection against the development of CM, besides hepatic and renal parameters better than CQ. In conclusion, this quinoline derivative demonstrated promising activity for the treatment of malaria and was able to avoid the development of severe malaria in mice.

Ectasia vascular do antro gástrico (estômago em melancia) ­ um relato de caso / Gastric antral vascular ectasia (watermelon stomach) ­ a case report

A Ectasia Vascular do Antro Gástrico (EVAG) é uma condição rara associada à hemorragia digestiva e anemia significativa. Acomete principalmente idosos e mulheres. É considerada uma anormalidade adquirida, resultando em ectasia da mucosa e da microvasculatura gástrica e é identificada na endoscopia digestiva alta (EDA). O diagnóstico pode se tornar complexo, pois a sua aparência endoscópica assemelha-se à gastropatia portal hipertensiva (GPH) ou à gastrite antral¹ , ². Este estudo tem como objetivo relatar um caso de EVAG e notificar a importância do conhecimento desta patologia, bem como a inclusão no diagnóstico diferencial à doenças como GPH e gastrite antral, para conduzir ao tratamento apropriado, pois apresenta bom prognóstico. Trata-se de um estudo descritivo, no qual foi relatado caso de paciente masculino, 76 anos, que procurou atendimento médico por acentuada anemia e melena. O paciente apresentava quadro anêmico há 6 meses, associado à fadiga, palidez e histórico de múltiplas transfusões sanguíneas. Foi requisitado EDA, o qual apresentou colunas vermelhas longitudinais no antro gástrico, possibilitando a associação com a clínica e seu diagnóstico. O paciente foi conduzido para terapêutica com o Coagulador de Plasma de Argônio e apresentou boa evolução4 . Pacientes idosos que apresentam anemia crônica sem causa aparente e/ou hemorragia digestiva alta, associada com a sintomatologia citada, devem ser endoscopicamente investigados para EVAG³. O diagnóstico desta patologia é muitas vezes dificultado, já que existem outras causas mais comuns de hemorragia digestiva, que mascaram o diagnóstico. Desta forma, destaca-se a importância do conhecimento dessa enfermidade, pois o tratamento adequado apresenta-se eficaz.

Gastric Antral Vascular Ectasia (GAVE) is a rare condition associated with digestive hemorrhage and significant anemia. It mainly affects elderly and women. It is considered an acquired abnormality, resulting in mucosal ectasia and gastric microvasculature and is identified in upper digestive endoscopy (EDA). The diagnosis can become complex, since its endoscopic appearance resembles hypertensive portal gastropathy (GPH) or antral gastritis¹, ². This study aims to report a case of GAVE and to notify the importance of the knowledge of this pathology, as well as the inclusion in the differential diagnosis to diseases such as GPH and antral gastritis, to lead to appropriate treatment, since it presents a good prognosis. This is a descriptive study, in which a case of a 76-year-old male patient who sought medical care for marked anemia and mane was reported. The patient presented an anemic condition for 6 months, associated with fatigue, pallor and history of multiple blood transfusions. EDA was requested, which presented longitudinal red columns in the gastric antrum, making possible the association with the clinic and its diagnosis. The patient was submitted to therapy with the Argon Plasma Coagulator and showed good evolution4. Elderly patients presenting with unexplained chronic anemia and / or upper gastrointestinal bleeding, associated with the mentioned symptomatology, should be endoscopically investigated for GAVE³. The diagnosis of this pathology is often difficult, since there are other more common causes of digestive hemorrhage, which mask the diagnosis. In this way, the importance of the knowledge of this disease is highlighted, since the appropriate treatment is effective.

Complete inventory of soybean NAC transcription factors: sequence conservation and expression analysis uncover their distinct roles in stress response.

We performed an inventory of soybean NAC transcription factors, in which 101 NAC domain-containing proteins were annotated into 15 different subgroups, showing a clear relationship between structure and function. The six previously described GmNAC proteins (GmNAC1 to GmNAC6) were located in the nucleus and a transactivation assay in yeast confirmed that GmNAC2, GmNAC3, GmNAC4 and GmNAC5 function as transactivators. We also analyzed the expression of the six NAC genes in response to a variety of stress conditions. GmNAC2, GmNAC3 and GmNAC4 were strongly induced by osmotic stress. GmNAC3 and GmNAC4 were also induced by ABA, JA and salinity but differed in their response to cold. Consistent with an involvement in cell death programs, the transient expression of GmNAC1, GmNAC5 and GmNAC6 in tobacco leaves resulted in cell death and enhanced expression of senescence markers. Our results indicate that the described soybean NACs are functionally non-redundant transcription factors involved in response to abiotic stresses and in cell death events in soybean.

Risk and protective factors for leprosy development determined by epidemiological surveillance of household contacts.

Household contacts of leprosy patients are the group with the highest risk of developing the disease, and although many risk or prevention factors have been identified, they have not been employed in leprosy-monitoring programs. This investigation aimed to establish the relative risks or the preventive effects of the presence of BCG vaccination, the Mitsuda test, and the ML-Flow assay. Household contacts (1,396) were monitored for a 5-year period. Twenty-eight contacts (2%) developed leprosy and had their clinical and operational classifications established. All immunological tests were performed, and intradermal BCG vaccination was given after the BCG scar count. Of the affected contacts, 75% developed the disease in the first year, and 71.4% were classified as having paucibacillary forms. Contacts of lepromatous leprosy patients presented a 3.8-fold-higher risk of developing leprosy. BCG vaccination and the Mitsuda test showed a protective effect against leprosy of 0.27 (at least one scar) and 0.16 (>7 mm), respectively, and the positive ML-Flow test indicated a relative risk approximately sixfold higher for occurrence of the disease. All unfavorable combinations of two and three assays generated significant risk values that ranged from 5.76 to 24.47, with the highest risk given by the combination of no BCG scar, negative Mitsuda test, and positive ML-Flow test. We suggest that the BCG vaccination may be given to stimulate Mitsuda test positivity, reducing the patient's risk of developing multibacillary forms. The high significance of these tests may have a great impact on programs to monitor contacts and should be used to improve early detection and treatment.

Obesidade e risco cardiometabólico / Obesity and Cardiometabolic Risk

A obesidade, mais do que simples desconforto estético, delimitou-senas últimas décadas como ressonante fator de risco associado a diversas doenças , estando entre os mais graves problemas de saúde pública. Sua prevalência está em franco crescimento , inclusive nos países em desenvolvimento , conferindo-lhe a condição de pandemia. Acredita-se que a adoção do estilo de vida "conteporâneo" , baseado em maior aporte calórico alimentar e sedentarismo atuando sobre carga de genes suscetíveis, seja o determinante principal do crescimento da obesidade no mundo. Esse fenômeno de transição comportamental e epidemiológica implica o incremento exponencial das taxas de mortalidade e morbidade decorrentes de doenças relacionadas à obesidade , particularmente as cardiovasculares e as cerebrovasculares. O excesso de peso e a obesidade abdominal provocam alterações orgânicas diversas e significativas, como resistência à ação da insulina , hipertensão arterial sistêmica, diabetes melito e dislipidemia, além de serem fatores de risco independente associados a doenças cardiovasculares. Investigações recentes demonstraram que as células de gordura são mais do que simplesmente repositórios de energia, constituindo-se em estruturas endócrinas metabolicaente ativas , secretoras de substâncias que podem influenciar a carga hemodinâmica, alterar a função endotelial, elevar níveis de marcadores inflamatórios e promover estado pró-trombótico. Diante desses novos conceitos e da existência de dados epidemiológicos exepressivos, torna-se imperativa...

Cognitive decline in temporal lobe epilepsy due to unilateral hippocampal sclerosis.

OBJECTIVE: We assessed the cognitive performance of patients with temporal lobe epilepsy (TLE) caused by unilateral hippocampal sclerosis (HS), in comparison with that of matched, healthy controls. We report the relationship between cognitive measures and duration of epilepsy, correlating with hippocampal volumes, and the impact of educational level on cognitive decline. METHODS: This study involved 61 outpatients (40 with < or = 8 years and 21 with >8 years of formal education) with unilateral HS and 61 controls. Volumetric MRI was performed on all patients and 10 controls. The results (mean, SD) of the neuropsychological tests of healthy subjects and patients were compared using the Student t and Mann-Whitney tests. RESULTS: Patients performed worse than controls in the neuropsychological evaluation. When adjusted z scores were used to calculate the impairment index, patients had a greater percentage of abnormal tests compared with controls. The cognitive decline, assessed through the impairment index, correlated with duration of epilepsy. Higher level of education did not protect against this decline, thus not supporting the hypothesis of cerebral reserve in this population. A significant correlation between hippocampal volumetric measures and duration of epilepsy was observed only in patients with left HS. CONCLUSION: Patients with TLE caused by HS present with cognitive morbidity that extends beyond memory deficits. Cognitive decline is associated with duration of epilepsy, and in patients with left-sided HS, duration may correlate with volumetric hippocampal loss.

Validity and reliability of the Portuguese version of the quality of life in epilepsy inventory (QOLIE-31) for Brazil.

PURPOSE: We report the cultural adaptation and psychometric properties of the Quality of Life in Epilepsy-31 Inventory (QOLIE-31) for the Portuguese language and Brazilian culture. METHODS: This study involved 150 outpatients: 50 presurgical patients with refractory temporal lobe epilepsy (TLE) related to mesial temporal sclerosis (MTS), 50 patients with juvenile myoclonic epilepsy (JME), and 50 seizure-free patients with TLE. They completed the QOLIE-31, Nottingham Health Profile (NHP), Beck Depression Inventory (BDI), and Adverse Events Profile (AEP) and underwent a neuropsychological evaluation (NE). Internal consistency reliability, interrater and test-retest reliability, and construct validity were assessed. RESULTS: QOLIE-31 mean scores were 33.1 (Social Function), 68.9 (Overall Quality of Life), 56.5 (Seizure Worry), 64.1 (Emotional Well-Being), 63.7 (Energy/Fatigue), 38.9 (Cognitive Function), and 49.7 (Medication Effects). Internal consistency was high (Cronbach's alpha), as were the associations between QOLIE-31 and the BDI, NHP, AEP, and NE. CONCLUSION: The Portuguese/Brazilian version of the QOLIE-31 inventory showed good reliability, validity, and construct validity.
