ABSTRACT

Introdução: A leucemia é o tipo de neoplasia mais comumente diagnosticada em crianças no mundo, afetando-as em um período crítico do desenvolvimento neuropsicomotor. Estando diagnosticadas com uma doença ameaçadora da vida, essas crianças necessitam, concomitantemente aos cuidados curativos, de cuidados paliativos. Objetivo: Avaliar a funcionalidade de crianças com leucemia durante o tratamento quimioterápico e compará-la no início e depois de um ano de tratamento em curso. Método: Estudo de corte transversal, do tipo observacional analítico, com 37 crianças avaliadas por meio de entrevista com os pais, utilizando um formulário de pesquisa e o Inventário de Avaliação Pediátrica de Incapacidade (PEDI). A análise estatística foi realizada pelos testes t de Student e de Mann-Whitney. Resultados: Não foram encontradas diferenças estatisticamente significantes entre a funcionalidade de crianças no início e depois de um ano de tratamento, estando todas com a funcionalidade abaixo do esperado para a faixa etária. Conclusão: Como forma de evitar possíveis atrasos e/ou déficits irreversíveis no desenvolvimento dessas crianças, sugere-se a criação de um programa de reabilitação em cuidados paliativos nos serviços especializados para cuidar desse público desde o diagnóstico

ABSTRACT

L-Asparaginase catalysing the breakdown of L-Asparagine to L-Aspartate and ammonia is an enzyme of therapeutic importance in the treatment of cancer, especially the lymphomas and leukaemia. The present study describes the recombinant production, properties and anticancer potential of enzyme from a hyperthermophilic archaeon Pyrococcus abyssi. There are two genes coding for asparaginase in the genome of this organism. A 918 bp gene encoding 305 amino acids was PCR amplified and cloned in BL21 (DE3) strain of E. coli using pET28a (+) plasmid. The production of recombinant enzyme was induced under 0.5mM IPTG, purified by selective heat denaturation and ion exchange chromatography. Purified enzyme was analyzed for kinetics, in silico structure and anticancer properties. The recombinant enzyme has shown a molecular weight of 33 kDa, specific activity of 1175 U/mg, KM value 2.05mM, optimum temperature and pH 80°C and 8 respectively. No detectable enzyme activity found when L-Glutamine was used as the substrate. In silico studies have shown that the enzyme exists as a homodimer having Arg11, Ala87, Thr110, His112, Gln142, Leu172, and Lys232 being the putative active site residues. The free energy change calculated by molecular docking studies of enzyme and substrate was found as ∆G – 4.5 kJ/mole indicating the affinity of enzyme with the substrate. IC50 values of 5U/mL to 7.5U/mL were determined for FB, caco2 cells and HepG2 cells. A calculated amount of enzyme (5U/mL) exhibited 78% to 55% growth inhibition of caco2 and HepG2 cells. In conclusion, the recombinant enzyme produced and characterized in the present study offers a good candidate for the treatment of cancer. The procedures adopted in the present study can be prolonged for in vivo studies.


A L-asparaginase, que catalisa a degradação da L-asparagina em L-aspartato e amônia, é uma enzima de importância terapêutica no tratamento do câncer, especialmente dos linfomas e da leucemia. O presente estudo descreve a produção recombinante, propriedades e potencial anticancerígeno da enzima de Pyrococcus abyssi, um archaeon hipertermofílico. Existem dois genes que codificam para a asparaginase no genoma desse organismo. Um gene de 918 bp, que codifica 305 aminoácidos, foi amplificado por PCR e clonado na cepa BL21 (DE3) de E. coli usando o plasmídeo pET28a (+). A produção da enzima recombinante foi induzida sob 0,5mM de IPTG, purificada por desnaturação seletiva por calor e cromatografia de troca iônica. A enzima purificada foi analisada quanto à cinética, estrutura in silico e propriedades anticancerígenas. A enzima recombinante apresentou peso molecular de 33 kDa, atividade específica de 1.175 U / mg, valor de KM 2,05 mM, temperatura ótima de 80º C e pH 8. Nenhuma atividade enzimática detectável foi encontrada quando a L-glutamina foi usada como substrato. Estudos in silico mostraram que a enzima existe como um homodímero, com Arg11, Ala87, Thr110, His112, Gln142, Leu172 e Lys232 sendo os resíduos do local ativo putativo. A mudança de energia livre calculada por estudos de docking molecular da enzima e do substrato foi encontrada como ∆G – 4,5 kJ / mol, indicando a afinidade da enzima com o substrato. Valores de IC50 de 5U / mL a 7,5U / mL foram determinados para células FB, células caco2 e células HepG2. Uma quantidade de enzima (5U / mL) apresentou inibição de crescimento de 78% a 55% das células caco2 e HepG2, respectivamente. Em conclusão, a enzima recombinante produzida e caracterizada no presente estudo é uma boa possibilidade para o tratamento do câncer. Os procedimentos adotados na presente pesquisa podem ser aplicados para estudos in vivo.

ABSTRACT

RESUMO Objetivo Identificar a ocorrência de disfunções orofaciais em pacientes infantojuvenis com leucemia aguda, submetidos à quimioterapia de remissão. Métodos Em um período de 16 meses, 40 pacientes com leucemias agudas, entre 3 e 18 anos de idade, foram admitidos em um hemocentro no estado do Amazonas. Destes, 23 foram incluídos neste estudo transversal e submetidos à avaliação das funções orofaciais, por meio do Nordic Orofacial Test-Screening (NOT-S), entre o trigésimo (D30) e o trigésimo terceiro dia (D33) da fase de indução da remissão. A presença de manifestações orais também foi avaliada por meio de exame clínico. Resultados Disfunção orofacial foi observada em, aproximadamente, metade dos casos avaliados (n=11). Destes pacientes, todos tiveram o domínio Secura de Boca (VI) alterado e 81,8% (n=9) apresentaram alteração no domínio Mastigação e Deglutição (IV). Mucosites em lábios, língua, soalho e orofaringe foram as lesões orais mais encontradas após a fase de indução. Houve associação entre a ocorrência de lesões orais nos pacientes avaliados e a presença de disfunção orofacial, segundo o NOT-S (IC 95%, p-valor = 0,027). Conclusão Sugere-se que a disfunção orofacial seja frequente na fase de indução da remissão em pacientes infantojuvenis com leucemias agudas. Estudos sobre as disfunções orofaciais nessa população, bem como sua relação com as lesões orais são necessários para melhor esclarecimento e compreensão dos impactos funcionais.


ABSTRACT Purpose To Identify the occurrence of orofacial dysfunctions in young children and adolescents with acute leukemia who are undergoing remission chemotherapy. Methods Over a period of 16 months, 40 three to eighteen year -old patients with acute leukemia were admitted to the Amazonas State Hemocenter. Of these, 23 were included in the cross-sectional study and submitted to the evaluation of orofacial functions using the Nordic Orofacial Test-Screening, between D30 and D33 of the remission induction phase. The presence of oral manifestations was also evaluated via clinical examination. Results Orofacial dysfunction was observed in approximately half of the evaluated cases (n=11). Of these patients, all had alterations in the Dryness of the Mouth (VI) domain and 81.8% (n=9) showed alterations in the Chewing and Swallowing (IV) domain. Mucosites on lips, tongue, floor of the mouth and the oropharynx were the most commonly found oral lesions after the remission induction phase. According to the NOT-S, there was an association between the occurrence of oral lesions in the evaluated patients and the presence of orofacial dysfunction (95% CI, p-value = 0.027). Conclusion It is suggested that orofacial dysfunction is frequent in the remission induction phase in children and adolescents with acute leukemia. Studies regarding these orofacial dysfunctions in this population, as well as their relationship with oral lesions, are needed in order to fully understand their functional impact.

ABSTRACT

Introdução: O potencial de transformação maligna de células-tronco hematopoiéticas portadoras de mutações no gene glicosilfostatidilinositolclasse A (PIG-A) para leucemias agudas, embora raro, já é bem descrito na literatura. Objetivo: Neste estudo, porém, buscou-se evidenciar pela primeira vez na literatura o surgimento ou a manutenção de clones de hemoglobinúria paroxística noturna (HPN) em pacientes diagnosticados com leucemia aguda ou ainda após o início do tratamento quimioterápico. Método: A pesquisa de clones de HPN foi realizada por citometria de fluxo em blastos, hemácias, granulócitos ou monócitos de 47 amostras de sangue periférico e medula óssea de pacientes submetidos à investigação diagnóstica ou acompanhamento terapêutico, provenientes de dois hospitais oncológicos e públicos de Belém, no período de dezembro de 2017 a dezembro de 2018. Resultados: A presença de clones de HPN foi observada em 19/47 (40,4%) amostras de pacientes, em investigação diagnóstica ou acompanhamento terapêutico, que realizaram pelo menos um estudo de acompanhamento terapêutico e ainda tiveram o surgimento ou a manutenção do clone de HPN mesmo após iniciado o tratamento quimioterápico. Conclusão: Foi possível evidenciar, de forma primária, a presença de clones de HPN em pacientes diagnosticados com leucemia aguda tanto no período de investigação diagnóstica como durante o acompanhamento terapêutico, independentemente da ontogenia celular. Sem, porém, que se possa ainda avaliar a importância da presença desses clones de HPN para a evolução da doença primária, prognóstico ou necessidade de tratamento específico.


Introduction: The potential for malignant transformation of hematopoietic stem cells carrying mutations in theglycosylphosphatidylinositol class A (PIG-A) gene for acute leukemias, although rare, is already well described in the literature. Objective: In this study, however, it was attempted to show for the first time in the literature the emergence or maintenance of paroxysmal nocturnal hemoglobinuria (PNH) clones in patients diagnosed with acute leukemia or even after the beginning of the chemotherapy treatment. Method: The search of PNH clones was performed by flow cytometry in blasts, erythrocytes, granulocytes or monocytes of 47 samples of peripheral blood and bone marrow from patients undergoing diagnostic investigation or therapeutic follow-up in two oncological and public hospitals in Belém, from December 2017 to December 2018. Results: The presence of PNH clones was observed in 19/47 (40.4%) patient samples, in diagnostic investigation or therapeutic follow-up, who participated of at least one therapeutic follow-up study and still experience the appearance or maintenance of the PNH clone even after the beginning of the chemotherapy treatment. Conclusion: Primarily, it was possible to demonstrate the presence of PNH clones in patients diagnosed with acute leukemia both during the diagnostic investigation period and therapeutic follow-up, regardless of cell ontogeny. However, the importance of the presence of these PNH clones for the evolution of the primary disease, prognosis or need for specific treatment was not evaluated yet.

ABSTRACT

Oxidative stress is caused by the imbalance between the generation of free radicals/reactive oxygen species (ROS) and the antioxidant defense systems, which can activate various transcription factors and affect their transcriptional pathways. Oxidative stress plays an important role in the occurrence and development of leukemia and is closely related to the treatment and prognosis of leukemia. The standard chemotherapy strategies for the pre-treatment of leukemia have many drawbacks. Hence, the usage of antioxidants and oxidants in the treatment of leukemia is being explored and has been preliminarily applied. This article reviews the research progress of oxidative stress and leukemia. In addition, the application of antioxidants treatment in leukemia has been summarized.

Introdução: O estado nutricional em fase pré-tratamento pode estar relacionado a desfechos clínicos desfavoráveis em pacientes com câncer. Objetivo: Avaliar o estado nutricional de pacientes adultos e idosos com leucemia em fase de pré-tratamento oncológico. Método: Trata-se de um estudo transversal, retrospectivo, envolvendo pacientes com leucemia em fase pré-tratamento oncológico. Os critérios de inclusão foram ≥20 anos de idade; ambos os sexos; e matrícula no Instituto Nacional de Câncer José Alencar Gomes da Silva (INCA). Os critérios de exclusão foram não ter diagnóstico confirmado de leucemia; registro de avaliação do estado nutricional por meio da avaliação subjetiva global produzida pelo paciente; e não ter recebido tratamento oncológico prévio. Os testes qui-quadrado e t deStudent foram utilizados. Resultados: Foram avaliados 69 pacientes com leucemia em fase pré-tratamento oncológico, sendo em sua maioria homens (52,2%) com menos de 60 anos de idade (52,2%). A prevalência de desnutrição foi de 65,2%, sendo mais expressiva nos idosos (78,8%, p=0,023). A prevalência de risco nutricional apresentou a mesma frequência (65,2%), no entanto, foi maior em pacientes com comorbidades (80,8%, p=0,017) e história de tabagismo (90,9%, p=0,056). Conclusão: A maior parte dos pacientes com leucemia iniciou seu tratamento oncológico com o estado nutricional debilitado, o que se exacerbou entre aqueles com leucemia crônica, idosos, com comorbidades e história de tabagismo.


Introduction: The nutritional status in the pretreatment phase may be related to unfavorable clinical outcomes in cancer patients. Objective: To assess the nutritional status of adult and older adults patients with leukemia in the pretreatment cancer phase. Method: Cross-sectional, retrospective study, involving patients with leukemia in the pretreatment cancer phase. The inclusion criteria were: ≥20 years of age, both genders and enrollment at the National Cancer Institute José Alencar Gomes da Silva (INCA). The exclusion criteria were not having confirmed diagnosis of leukemia, registration of the Patient-Generated Subjective Global Assessment and not having submitted to previous cancer treatment. Chi-square and Student's t tests were used. Results: 69 patients were evaluated with leukemia in the pretreatment cancer phase, mostly men (52.2%) under 60 years of age (52.2%). The prevalence of malnutrition was 65.2%, being more expressive in the older adults (78.8%, p=0.023). The prevalence of nutritional risk had the same frequency (65.2%), however it was higher in patients with comorbidities (80.8%, p=0.017) and smoking history (90.9%, p=0.056). Conclusion: Most patients with leukemia started their cancer treatment with impaired nutritional status, which was exacerbated for those with chronic leukemia, older adults, with comorbidities and history of smoking.

ABSTRACT

Introdução: A manipulação de antineoplásicos para ajuste de dose, como partição de comprimidos, é comum no tratamento de leucemias agudas de crianças e adolescentes. Objetivo: Identificar a frequência e descrever a prática da partição domiciliar de comprimidos antineoplásicos utilizados no tratamento oral de crianças e adolescentes com leucemias agudas na fase de manutenção. Método: Trata-se de um estudo transversal descritivo, realizado em um hospital pertencente à rede de saúde pública do Distrito Federal com assistência especializada em pediatria. Foram incluídos no estudo crianças e adolescentes entre 1 e 18 anos, diagnosticados com leucemias agudas e em fase de manutenção do tratamento no período de estudo. Foi aplicado um questionário semiestruturado ao responsável principal pela administração dos medicamentos quimioterápicos via oral, podendo ser o cuidador ou a própria criança/adolescente. Foram coletadas variáveis sociodemográficas dos pacientes e cuidadores e variáveis sobre a prática de partição de medicamentos antineoplásicos no domicílio. Resultados: Todos os 48 entrevistados no período do estudo relataram ter partido comprimidos antineoplásicos ao longo do tratamento de leucemias agudas, sendo estes mercaptopurina (n=45 [93,75%]) e tioguanina (n=3 [6,25%]). Conclusão: A partição de comprimidos antineoplásicos foi uma prática unânime em virtude da necessidade referida de ajuste de dose individual para o tratamento de leucemias agudas de crianças e adolescentes, considerando a indisponibilidade de formulações adequadas. Os resultados reforçam a necessidade de a partição ser uniformizada e realizada de maneira a minimizar os riscos e a garantir a segurança para as crianças e adolescentes e seus cuidadores.


Introduction: Antineoplastic drug manipulation for dose adjustment, such as tablet splitting, is standard in acute leukemia treatment for children and adolescents. Objective: To identify the frequency and describe the practice of household splitting of antineoplastic tablet for oral treatment of children and adolescents with acute leukemias in the maintenance phase. Method: Cross-sectional descriptive study performed in a public health system hospital from Distrito Federal (Brazil) with specialized pediatric assistance. Children and teenagers between 1 and 18 years old, diagnosed with acute leukemia and in treatment maintenance phase during the study period were included. A semi-structured questionnaire was applied to the main responsible for administering oral chemotherapy drugs, which could be the caregiver or the child/adolescent themselves. Sociodemographic variables of patients and caregivers and variables on the practice of splitting antineoplastic drugs at home were collected. Results: All 48 interviewees in the study period reported having split antineoplastic tablets during the treatment for acute leukemias, such as mercaptopurine (n = 45 [93.75%]) and thioguanine (n = 3 [6.25%]). Conclusion: The splitting of antineoplastic tablets was a unanimous practice due to the reported need to adjust the individual dose for acute leukemia treatment in children and adolescents, considering the unavailability of adequate formulations. The results reinforce the need for splitting to be standardized and performed in a way that minimizes risks and ensures safety for patients and their caregivers


Introducción: La manipulación de fármacos antineoplásicos para el ajuste de dosis, como las particiones de comprimidos, es frecuente en el tratamiento de las leucemias agudas en niños y jóvenes. Objetivo: Identificar la frecuencia y describir la práctica de la división domiciliaria de medicamentos antineoplásicos utilizados en el tratamiento oral de niños y adolescentes con leucemias agudas en la fase de mantenimiento. Método: Se trata de un estudio transversal descriptivo realizado en un hospital de la red de salud pública del Distrito Federal (Brasil) con asistencia especializada en pediatría. El estudio incluyó a niños y jóvenes de entre 1 y 18 años de edad diagnosticados con leucemia aguda y en fase de mantenimiento del tratamiento en el período del estudio. Se aplicó un cuestionario semiestructurado a la persona principal responsable de la administración de fármacos quimioterapéuticos por vía oral, que puede ser el cuidador o el propio niño/joven. Fueron colectadas variables sociodemográficas de los pacientes y cuidadores y variables sobre la práctica de la división de los medicamentos antineoplásicos en domicílios. Resultados: Los 48 entrevistados en el período de estudio informaron haber roto las pastillas antineoplásicas durante el tratamiento de la leucemia aguda, siendo éstas mercaptopurina (n=45 [93,75%]) y tioguanina (n=3 [6,25%]). Conclusión: La partición de comprimidos antineoplásicos fue una práctica unánime debido a la necesidad mencionada de ajustar la dosis individual para el tratamiento de las leucemias agudas de niños y adolescentes, considerando la falta de formulaciones apropiadas. Los resultados refuerzan la necesidad de estandarizar y realizar la partición para minimizar los riesgos y garantizar la seguridad de los niños, jóvenes y sus cuidadores.

ABSTRACT

Resumen Introducción: Las neoplasias de células natural killer (NK) son poco frecuentes y representan <5% de todas las neoplasias linfoides. Comprometen diferentes entidades clínicas, como la leucemia de células NK, que es una neoplasia hematológica altamente agresiva con un pronóstico precario, que se presenta en hombres jóvenes y se observa con mayor frecuencia en ascendencia asiática. El virus de Epstein-Barr (VEB) parece estar relacionado con la patogenia de esta leucemia. Caso clínico: Se presenta el caso de un paciente de sexo masculino de 1 año y 7 meses de edad, quien inició su padecimiento con síndrome anémico, febril, infiltrativo e hiperleucocitosis. En el aspirado de médula ósea se detectaron blastos de morfología L2 (96%), inmunofenotipo CD56 (80.87%) y desoxinucleotidil transferasa terminal (84.11%). En la biopsia de médula ósea se identificó CD2+ membranoso, CD3+ citoplásmico y CD56+ membranoso; la serología para VEB fue positiva. El paciente recibió dos esquemas diferentes de quimioterapia basados en metotrexato, ifosfamida, etopósido, dexametasona y L-asparaginasa, y se documentó remisión parcial. Actualmente, se encuentra vivo con la enfermedad. Conclusiones: La leucemia de células NK es rara en adultos jóvenes, pero aún más en pacientes en edad pediátrica. Además, es de muy difícil tratamiento, ya que solo se cuenta con algunos reportes de casos, la sobrevida es de semanas a meses y las oportunidades de tratamiento se limitan. Recientemente, se ha evidenciado la utilidad del trasplante de médula ósea alogénico o células de cordón umbilical, y se ha logrado una sobrevida a 2 años. Las posibilidades terapéuticas en estos pacientes se encuentran en estudio. Se espera lograr en un futuro cercano la remisión completa y sobrevida a 5 años.


Abstract Background: Natural killer (NK) cell neoplasms are rare and represent <5% of all lymphoid neoplasms. They involve different clinical entities, of which one is NK cell leukemia, a highly aggressive hematologic neoplasm with poor prognosis that presents in young men and is more frequently seen in Asian descent. Epstein-Barr virus (EBV) seems to be related to the pathogenesis. Case report: A male patient of 1 year and 7 months of age, who began his condition with anemic, febrile, infiltrative syndrome and hyperleukocytosis is described. Bone marrow aspirate showed L2 morphology blasts (96%), CD56 (80.87%) and terminal deoxynucleotidyl transferase (84.11%) immunophenotype. Bone marrow biopsy showed membranous CD2+, cytoplasmic CD3+ and membranous CD56+; serology positive to EBV. The patient received two different chemotherapy schemes based on methotrexate, ifosfamide, etoposide, dexamethasone and L-asparaginase, which resulted in partial remission. Currently, the patient lives with the disease. Conclusions: NK cells leukemia is rare in young adults, but even more in pediatric patients, for which it is very difficult to treat because only a few cases have been reported in the literature, the survival varies from weeks to months and the chances of treatment are limited. Recently, the usefulness of allogeneic bone marrow transplantation or umbilical cord cells has been demonstrated, achieving a 2-year survival. The therapeutic possibilities in these patients are under study. In the near future, we hope to achieve the complete remission of the disease and a 5-year survival.

ABSTRACT

Type 2 diabetes mellitus and cancer are correlated with changes in insulin signaling, a pathway that is frequently upregulated in neoplastic tissue but impaired in tissues that are classically targeted by insulin in type 2 diabetes mellitus. Many antidiabetes treatments, particularly metformin, enhance insulin signaling, but this pathway can be inhibited by specific cancer treatments. The modulation of cancer growth by metformin and of insulin sensitivity by anticancer drugs is so common that this phenomenon is being studied in hundreds of clinical trials on cancer. Many meta-analyses have consistently shown a moderate but direct effect of body mass index on the incidence of multiple myeloma and lymphoma and the elevated risk of leukemia in adults. Moreover, new epidemiological and preclinical studies indicate metformin as a therapeutic agent in patients with leukemia, lymphomas, and multiple myeloma. In this article, we review current findings on the anticancer activities of metformin and the underlying mechanisms from preclinical and ongoing studies in hematologic malignancies.

ABSTRACT

Se realizó un estudio descriptivo y retrospectivo de 64 pacientes mayores de 60 años con leucemia aguda, atendidos en el Servicio de Hematología del Hospital General Docente "Dr. Juan Bruno Zayas Alfonso" de Santiago de Cuba, durante el quinquenio 2006-2011, para determinar las principales características clínicas y hematológicas en el momento del diagnóstico, así como la supervivencia global de los afectados, aunque los tratamientos administrados no tenían criterio curativo. La edad promedio de los ancianos fue de 70 años, en un rango etario de 60 a 90; en tanto, la variedad no linfoblástica representó 98,4 %, y todos los pacientes presentaron anemia y trombocitopenia como alteraciones hematológicas, con incremento en los requerimientos transfusionales. De igual forma, la presencia de blastos en la sangre periférica se demostró en 50 % y la hiperleucocitosis en 59,4 %, mientras las principales causas de muerte estuvieron relacionadas con la hemorragia cerebral y la progresión de la enfermedad con la infiltración multiorgánica, lo cual condujo a una supervivencia muy corta de los integrantes de la serie...


A descriptive and retrospective study of 64 patients older than 60 years with acute leukemia, assisted in the Hematology Service of "Dr. Juan Bruno Zayas Alfonso" Teaching General Hospital in Santiago de Cuba was carried out during the five year period 2006-2011, to determine the main clinical and hematological characteristics at the moment of diagnosis, as well as the global survival of those affected, although the administered treatments had no healing criterium. The average age of the elderly was 70 years, in an age range of 60 to 90; while the non lymphoblastic variety represented 98.4%, and all the patients presented anemia and thrombocytopenia hematological changes, with increment in the transfusional requirements. Likewise, the blastos presence in the peripheral blood was demonstrated in 50% and the hyperleucocytosis in 59.4%, while the main causes of death were related to the cerebral hemorrhage and the progression of the disease with the multiorganic infiltration, which led to a very short survival of the members of this series...

ABSTRACT

PURPOSE: The purpose of this study was to identify the factors relating to resilience for adolescents with leukemia and examine the relationship between these factors. METHODS: From June to September in 2014, 199 adolescents aged 11 to 21 participated in the study as they visited the out-patient clinic at C university hospital for follow-up care. To verify the predictors and the effects of resilience, uncertainty, symptom distress, perceived social support, spiritual perspective, defensive coping, courageous coping, hope, and self-transcendence were measured. Collected data were analyzed using hierarchical regression analysis with the SAS statistics program. RESULTS: The final regression model showed that courageous coping, hope, and self-transcendence were significant predictors related to resilience in adolescents with leukemia and explained for 63% of the variance in resilience. CONCLUSION: The findings indicate that adolescent-oriented intervention programs enhancing courageous coping, hope, and self-transcendence should be provide for adolescents with leukemia in order to overcome illness-related stress and support physical, psychological and social adjustment.

ABSTRACT

OBJECTIVE: The aim of this study was to assess the pulmonary function of children with acute leukemia. METHODS: Cross-sectional observational analytical study that enrolled 34 children divided into groups A (17 with acute leukemia in the maintenance phase of chemotherapy) and B (17 healthy children). The groups were matched for sex, age and height. Spirometry was measured using a spirometer Microloop Viasys(r) in accordance with American Thoracic Society and European Respiratory Society guidelines. Maximal respiratory pressures were measured with an MVD300 digital manometer (Globalmed(r)). Maximal inspiratory pressures and maximal expiratory pressures were measured from residual volume and total lung capacity, respectively. RESULTS: Group A showed a significant decrease in maximal inspiratory pressures when compared to group B. No significant difference was found between the spirometric values of the two groups, nor was there any difference between maximal inspiratory pressure and maximal expiratory pressure values in group A compared to the lower limit values proposed as reference. CONCLUSION: Children with acute leukemia, myeloid or lymphoid, during the maintenance phase of chemotherapy exhibited unchanged spirometric variables and maximal expiratory pressure; However, there was a decrease in inspiratory muscle strength...

ABSTRACT

Introduction: Febrile neutropenia (FN) is a common complication of patients undergoing chemotherapy (QMT). Clinical presentation is varied, from mild fever to severe sepsis with invasive bacterial infection (IBI) or invasive fungal infection (IFI), with great impact on prognosis and patient mortality. Patients and Methods: Prospective cohort study of FN episodes in adult patients with acute leukemia (AL) or lymphoma (L), diagnosed and treated at the Hospital Clínico Universidad Católica and Hospital Dr. Sótero del Río in Santiago from April 2010 to January 2012. Results: 130 patients were included with 105 episodes of NF, with an incidence of 0.65 per 100 days of observation, higher in AL than L (1.31 vs 0.25, p = 0.001). Etiology or clinical focus was documented in 67 (63.8%) episodes, with IBI in 33 (31.4%) and IFI in 21 (20%) cases. Mortality related to infection occurred in 4 (6.2%) patients. Conclusions: This study reports that the FN incidence and frequency of IBI and IFI during episodes are higher in AL vs. L. It is necessary to evaluate the impact of interventions to reduce its incidence, including the benefit and risk of using antibacterial and antifungal prophylaxis in high-risk subgroups.


Introducción: La neutropenia febril (NF) es una complicación frecuente de pacientes sometidos a quimioterapia (QMT). Su presentación clínica es amplia, desde cuadros leves a sepsis grave con infección bacteriana invasora (IBI) o infección fúngica invasora (IFI), con gran impacto en el pronóstico y mortalidad de los pacientes. Pacientes y Métodos: Estudio prospectivo de episodios de NF en cohorte de pacientes adultos con leucemia aguda (LA) o linfoma (L) diagnosticados y tratados en el Hospital Clínico Pontificia Universidad Católica de Chile y Hospital Dr. Sótero del Río en Santiago, desde abril de 2010 hasta enero de 2012. Resultados: Se reclutaron 130 pacientes que presentaron 105 episodios de NF, con incidencia de 0,65 por 100 días de observación, mayor en LA que en L (1,31 vs 0,25, p: 0,001), documentándose etiología o foco infeccioso en 67 (63,8%) de los episodios, con 33 (31,4%) IBI y 21 (20%) IFI. Hubo mortalidad relacionada a infección en 4 (6,2%) pacientes. Conclusiones: Se define la incidencia de NF (LA > L) y frecuencia de IBI e IFI durante el episodio (LA > L). Es necesario evaluar el impacto de intervenciones destinadas a disminuir la incidencia de NF, entre las que se debe incluir el beneficio y riesgo del uso sistemático de profilaxis antibacteriana y antifúngica en los subgrupos de mayor riesgo.

ABSTRACT

As narrativas surgem para ordenar a experiência humana alterada pela ruptura no seu estado canônico. Nesse sentido, uma doença como o câncer pode ser considerada uma experiência excepcional, que requer a narrativa para significá-la. Esse estudo investigou a construção de significados acerca do adoecimento e da morte nas narrativas de crianças com câncer em etapas distintas do tratamento. Para tanto, foram realizadas seis sessões de brincadeira com cada participante. A análise dos dados demonstrou que crianças com mais tempo de tratamento tendem a finalizar suas narrativas com a morte dos personagens e que crianças com menos tempo de tratamento apresentam narrativas relacionadas ao desconforto físico que o tratamento ocasiona e aos impedimentos que a doença acarreta em suas vidas. Esses resultados apontam para a necessidade de uma maior atenção à forma como as crianças falam do seu adoecimento e da subsequente possibilidade de morte no decorrer do tratamento oncológico, a fim de que possamos atentar para a diversidade dos momentos de tratamento, compreendendo que esses configuram diferentes relações subjetivas da criança para com sua doença e a morte.

Narratives come out to arrange the human experience altered by the disruption in its canonical status. In this sense, a disease like cancer can be considered an exceptional experience that requires the narrative to mean it. This study investigated the construction of meanings about the disease and death in the narratives of children with cancer in different stages of treatment. Thus, six sessions of play were performed with each child. Data analysis showed that children in longer treatment tend to conclude their narratives with the death of the characters and the children under shorter treatment time present narratives related both to physical discomfort to which the treatment leads to and impairments that the disease cause in their lives. The results indicate the need for greater attention on how children talk about the disease and the subsequent possibility of death during the course of cancer treatment, so that we can be aware of the diversity of treatment moments, understanding that they configure different subjective relationships about children's health problem and death.

ABSTRACT

Over the past few decades, L-asparaginase has emerged as an excellent anti-neoplastic agent. In present study, a new strain ITBHU02, isolated from soil site near degrading hospital waste, was investigated for the production of extracellular L-asparaginase. Further, it was renamed as Bacillus aryabhattai ITBHU02 based on its phenotypical features, biochemical characteristics, fatty acid methyl ester (FAME) profile and phylogenetic similarity of 16S rDNA sequences. The strain was found protease-deficient and its optimal growth occurred at 37 °C and pH 7.5. The strain was capable of producing enzyme L-asparaginase with maximum specific activity of 3.02±0.3 Umg-1 protein, when grown in un-optimized medium composition and physical parameters. In order to improve the production of L-asparaginase by the isolate, response surface methodology (RSM) and genetic algorithm (GA) based techniques were implemented. The data achieved through the statistical design matrix were used for regression analysis and analysis of variance studies. Furthermore, GA was implemented utilizing polynomial regression equation as a fitness function. Maximum average L-asparaginase productivity of 6.35 Umg-1 was found at GA optimized concentrations of 4.07, 0.82, 4.91, and 5.2 gL‑1 for KH2PO4, MgSO4.7H2O, L-asparagine, and glucose respectively. The GA optimized yield of the enzyme was 7.8% higher in comparison to the yield obtained through RSM based optimization.

ABSTRACT

Estudo descritivo, transversal desenvolvido com objetivo de associar aspectos socio demográficos e clínicos aos domínios de qualidade de vida relacionada à saúde (QVRS), para avaliar pacientes onco-hematológicos submetidos à quimioterapia. Na coleta de dados utilizou-se um instrumento sociodemográfico e clínico e o European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC) QLQ-C-30. A amostra foi constituída de 32 pacientes, sendo oito (25%) com diagnóstico de linfoma de Hodgkin, nove (28,12%) linfoma não Hodgkin e 15 (46,87%) leucemia. Os dados foram analisados pelo software Statistical Package for Social Science (SPSS). O QLQ-C-30 mostrou média das funções física, cognitiva, emocional, social e desempenho de papel de 54,81 a 41,18, demonstrando um nível pouco satisfatório. Nas escalas de sintomas, houve predomínio de fadiga média 64,57 seguida de insônia (56,90) e perda de apetite (50,71). Esses sintomas interferiram nas funções físicas, emocionais e cognitivas demonstrando que efeitos colaterais do tratamento influenciam negativamente na QVRS dos pacientes.


This descriptive and cross-sectional study aimed to examine the socio-demographic/clinical aspects of health-related quality of life (HRQoL) and assess the HRQoL of onco- hematological patients undergoing chemotherapy. The data collection instrument was a socio-demographic/clinical questionnaire, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC) QLQ-C-30. The sample consisted of 32 patients, eight of whom (25%) were diagnosed with Hodgkin's lymphoma; nine (28.12%), with non-Hodgkin's lymphoma; and 15 (46.87%), with leukemia. The data were analyzed using SPSS software. For the functional scales of the QLQ-C-30 (physical, cognitive, emotional, social and role performance), the mean scores ranged from 54.81 to 41.18, demonstrating an unsatisfactory level of functioning. In the symptom scales, there was a predominance of fatigue (64.57), insomnia (56.90) and loss of appetite (50.71). These symptoms interfered with the patients' physical functioning, demonstrating that the emotional and cognitive side effects of the treatment negatively influenced the HRQoL of the patients.

ABSTRACT

SUV39H1 is a histone 3 lysine 9 (H3K9)-specific methyltransferase that is important for heterochromatin formation and the regulation of gene expression. Chaetocin specifically inhibits SUV39H1, resulted in H3K9 methylation reduction as well as reactivation of silenced genes in cancer cells. Histone deacetylase (HDAC) inhibitors inhibit deacetylases and accumulate high levels of acetylation lead to cell cycle arrest and apoptosis. In this study, we demonstrated that treatment with chaetocin enhanced apoptosis in human leukemia HL60, KG1, Kasumi, K562, and THP1 cells. In addition, chaetocin induced the expression of cyclin-dependent kinase inhibitor 2B (p15), E-cadherin (CDH1) and frizzled family receptor 9 (FZD9) through depletion of SUV39H1 and reduced H3K9 methylation in their promoters. Co-treatment with chaetocin and HDAC inhibitor trichostatin A (TSA) dramatically increased apoptosis and produced greater activation of genes. Furthermore, this combined treatment significantly increased loss of SUV39H1 and reduced histone H3K9 trimethylation responses accompanied by increased acetylation. Importantly, co-treatment with chaetocin and TSA produced potent antileukemic effects in leukemia cells derived from patients. These in vitro findings suggest that combination therapy with SUV39H1 and HDAC inhibitors may be of potential value in the treatment of leukemia.
