Introduction. The pre-analytical phase is a vital component of the clinical analysis algorithm. This involves a series of steps and procedures. Objective. To describe the level of compliance with the preanalytical indicators in the areas of chemistry and haematology ofthe clinical laboratory at a local Hospital in Caaguazú. Materiales y método. Anon-experimental design and a mixed cross-sectional approach were applied. Three biochemists and one hundred patients were includer. Results. Our data was obtained by structured observation to patients and semi-structured interviews tothree biochemists. The level of performance of the biochemists about the pre-analytical indicators presents both positive and negative aspects, of which the positive aspect stands out in 61% and 39% corresponds to aspects considered as deficient. The existing difficulties are the correct identification of the patient and the communication between the treating physician and/or technician, most of whom are unaware ofthe conditions in which they should present themselves for a medical examination. Conclusion. The correct performance, as well as their quality, in the pre-analytical phase, is directly related to the results obtained, which the requesting professionals will later use for decision-making, so it is an initial link that affects the entire subsequent process and must always be considered essential.

Analysis of the clinical characteristics of acute myeloid leukemia related to the treatment of hematological and solid tumors / 中华肿瘤杂志

Objective: To compare and analyze the clinical characteristics of acute myeloid leukemia (AML) related to the treatment of hematological tumors and solid tumors. Methods: The laboratory and clinical data of 41 patients with treatment-related AML (t-AML) in the Department of Hematology, Henan Cancer Hospital from January 2014 to December 2021 were retrospectively analyzed, and they were divided into hematological tumor group and solid tumor group. Survival analysis was performed using the Kaplan-Meier method and Log rank test. Results: The median interval from the first tumor diagnosis to t-AML in 41 patients was 21.0 (16.5-46.0) months; 24 (58.5%) had abnormal expression of lymphoid antigen, 28 (68.3%) had abnormal karyotype, 18 cases (43.9%) were positive for fusion gene, and 28 cases (68.3%) were positive for gene mutation; the median recurrence-free survival (RFS) was 11.0 months, and the median overall survival (OS) was 11.5 months. The proportion of acute promyelocytic leukemia ([APL], 0.0, 0/13), complete response ([CR],18.2%, 2/11), median OS (4.5 months) and median RFS (2.5 months) of t-AML patients in the hematological tumor group were significantly lower than those in the solid tumor group (35.7%, 10/28; 68.0%, 17/25; not reach; not reach), but the proportion of M4 /M5 (93.2%,12/13) was significantly higher than that in the solid tumor group (53.6%,15/18; all P values<0.05). Through subgroup analysis, the proportion of patients with positive PML-RARa and good prognosis karyotypes in the solid tumor group (35.7%, 10/28; 46.4%, 13/28) was significantly higher than that in the hematological tumor group (0.0, 0/13; 0.0, 0/13; P<0.05), while the proportion of patients with intermediate karyotypes (42.9%, 12/28) was significantly lower than that in the hematological tumor group (84.6%, 11/13; P<0.05), the difference was statistically significant. The CR rate (90.0%, 9/10), median OS (not reach) and median RFS (not reach) in the t-APL group were higher than those in the t-AML (without t-APL) group (38.5%, 10/26; 6 months; 8 months; P<0.05). After excluding the effect of t-APL patients, there was no significant difference in the CR rate, median OS and median RFS between the solid tumor group (8; 9 months; not reach) and the hematological tumor group (2; 4 months; 2 months; P>0.05). Univariate analysis showed that the primary tumor belongs to hematological tumor was a common risk factor for OS and RFS in t-AML patients (P<0.10). Conclusions: Compared with patients with t-AML secondary to solid tumors, patients with t-AML secondary to hematological tumors have poorer treatment effects and poorer prognosis. After excluding the effect of t-APL patients, there are no significant differences in the treatment efficacy and prognosis between the two types of t-AML patients.

Consensus of the Brazilian association of hematology, hemotherapy and cellular therapy on patient blood management: Preoperative Clinical and Laboratory Assessment of the Patient

Abstract The preoperative clinical and laboratory evaluations of the patient is an essential step to ensure the safety and success of any surgical procedure. This assessment aims to identify any underlying medical conditions and risk factors and determine suitability for surgery. With this step, the medical team can adapt the care plan to meet each patient's specific needs, increasing the chances of a successful procedure. Good clinical assessment and comprehensive laboratory testing, when integrated into a Patient Blood Management approach, are invaluable in promoting safety of care, reducing transfusion risks, improving surgical outcomes, and optimizing resource utilization. This approach not only elevates the quality of care, but is also aligned with evidence-based practice and patient-centered principles, making it an essential component of the perioperative process.

Dental care for children in a tertiary hospital

Aim: To evaluate the profile of pediatric onco-hematological patients and the outpatient dental care provided to these individuals from January 2016 to December 2019 by the Pediatric Dentistry division of the Dentistry and Stomatology Service of a tertiary hospital. Methods: Data were collected from the medical records of 179 pediatric patients undergoing treatment for onco-hematological diseases, aged between 0 and 19 years, regarding their profile and the outpatient dental care provided by the Pediatric Dentistry Service of the Dentistry and Stomatology Service of a tertiary hospital. Data were tabulated and subjected to descriptive statistical analysis. Results: The majority of the patients were male, with a mean age of 12. Anemia and leukemia were the most prevalent diseases in this study. During the evaluation period, 1548 dental appointments were performed, 696 of which were clinical evaluations. The remaining appointments involved various dental procedures. The most common procedures included the topical application of fluoride and dental prophylaxis, followed by extractions, laser therapy, tooth decay removal, and restorations/sealants. Conclusion: Assessing patient profiles and the dental care provided are important tools for improving dental care protocols and enhancing the quality of life for pediatric onco-hematological patients

A Doença Renal Crônica (DRC) é uma importante redução da função renal que causa alterações no metabolismo dos indivíduos. Para acompanhar a progressão da DRC e prevenir possíveis complicações, foi realizada uma pesquisa para avaliar o perfil sociodemográfico, bioquímico e hematológico de pacientes com Insuficiência Renal Crônica (IRC) submetidos a hemodiálise. Esta pesquisa foi quantitativa, descritiva e transversal de caráter retrospectivo, realizada por meio da análise de dados secundários contidos nos prontuários dos pacientes. A coleta de dados ocorreu no Centro de Hemodiálise da cidade de Russas, no Ceará. A amostra foi constituída por 161 pacientes com DRC, sendo 63,35% do sexo masculino e 85,71% pardos, com uma idade média de 54,39 anos. Desses, 63,97% tinham entre 2 e 10 anos de tratamento e 57,76% possuíam ensino fundamental incompleto. 19,25% residiam em Russas. Resultados: Após a hemodiálise, os resultados mostraram 44 mg/dL de Ureia, 48,44% dos pacientes com valores normais. A hemoglobina e hematócrito médios foram 11,8 g/dL e 33,7%, respectivamente, sendo que 63,35% tiveram valores reduzidos. 85,10% dos pacientes tiveram contagem de plaquetas normal, 72,04% níveis adequados de ferro e albumina, 52,79% tiveram níveis elevados de ferritina, 23,61% redução de transferrina e níveis lipídicos satisfatórios. 79,50% apresentaram níveis séricos de potássio dentro da normalidade, 12,42% de fósforo acima do normal, 85,09% de cálcio dentro dos valores normais, 39,13% de PTHi normais e 86,33% de glicose dentro dos valores considerados normais. Com base nos resultados, concluiu-se que todos os pacientes em tratamento hemodialítico apresentam diversas alterações em decorrência da DRC e do próprio processo de tratamento. Portanto, a realização de exames para avaliar ou monitorar possíveis complicações da IRC é essencial para criar estratégias e intervenções mais eficazes, que melhorem a assistência prestada a esses pacientes e, consequentemente, da qualidade e expectativa de vida dos mesmos.

Chronic Kidney Disease (CKD) is an important reduction in kidney function that causes changes in the metabolism of individuals. To monitor the progression of CKD and prevent possible complications, a survey was carried out to assess the sociodemographic, biochemical and hematological profile of patients with Chronic Renal Failure (CRF) undergoing hemodialysis. This research was quantitative, descriptive and cross-sectional with a retrospective character, carried out through the analysis of secondary data contained in the patients' medical records. Data collection took place at the Hemodialysis Center in the city of Russas, Ceará. The sample consisted of 161 patients with CKD, 63.35% male and 85.71% brown, with an average age of 54.39 years. Of these, 63.97% had between 2 and 10 years of treatment and 57.76% had incomplete primary education. 19.25% resided in Russas. Results: After hemodialysis, the results showed 44 mg/dL of Urea, 48.44% of patients with normal values. Average hemoglobin and hematocrit were 11.8 g/dL and 33.7%, respectively, with 63.35% having reduced values. 85.10% of the patients had normal platelet counts, 72.04% had adequate levels of iron and albumin, 52.79% had high levels of ferritin, 23.61% had reduced transferrin and satisfactory lipid levels. 79.50% had serum levels of potassium within the normal range, 12.42% of phosphorus above normal, 85.09% of calcium within normal values, 39.13% of PTHi normal and 86.33% of glucose within the values considered normal. Based on the results, it was concluded that all patients on hemodialysis have several changes due to CKD and the treatment process itself. Therefore, carrying out tests to assess or monitor possible complications of CRF is essential to create more effective strategies and interventions that improve the care provided to these patients and, consequently, their quality and life expectancy.

Para monitorizar la evolución de la ERC y prevenir posibles complicaciones, se realizó una encuesta para evaluar el perfil sociodemográfico, bioquímico y hematológico de los pacientes con Insuficiencia Renal Crónica (IRC) en hemodiálisis. Esta investigación fue cuantitativa, descriptiva y transversal con carácter retrospectivo, realizada a través del análisis de datos secundarios contenidos en las historias clínicas de los pacientes. La recolección de datos ocurrió en el Centro de Hemodiálisis de la ciudad de Russas, Ceará. La muestra estuvo constituida por 161 pacientes con ERC, 63,35% del sexo masculino y 85,71% pardos, con una edad media de 54,39 años. De estos, 63,97% tenían entre 2 y 10 años de tratamiento y 57,76% tenían primaria incompleta. El 19,25% residía en Russas. Resultados: Posterior a la hemodiálisis los resultados arrojaron 44 mg/dL de Urea, 48,44% de los pacientes con valores normales. La hemoglobina y el hematocrito medios fueron 11,8 g/dl y 33,7 %, respectivamente, con un 63,35 % con valores reducidos. El 85,10% de los pacientes presentaba plaquetas normales, el 72,04% presentaba niveles adecuados de hierro y albúmina, el 52,79% presentaba niveles elevados de ferritina, el 23,61% presentaba transferrina reducida y niveles satisfactorios de lípidos. El 79,50% presentaba niveles séricos de potasio dentro de la normalidad, el 12,42% de fósforo por encima de lo normal, el 85,09% de calcio dentro de los valores normales, el 39,13% de PTHi normal y el 86,33% de glucosa dentro de los valores considerados normales. Con base en los resultados, se concluyó que todos los pacientes en hemodiálisis tienen varios cambios debido a la ERC y al propio proceso de tratamiento. Por tanto, la realización de pruebas para evaluar o monitorizar las posibles complicaciones de la IRC es fundamental para crear estrategias e intervenciones más eficaces que mejoren la atención a estos pacientes y, en consecuencia, su calidad y esperanza de vida.

Career paths and workforce diversity in hematology: A cross-sectional study of a 35-year alumni cohort from an academic residency program in Brazil

ABSTRACT Introduction: Although not mandatory, medical residency has become a sine qua non condition for practicing in most medical specialties in Brazil. Residency programs are hosted mainly by university accredited academic centers and hospitals in the national public healthcare system, under guidance and accreditation by a national commission. Despite the importance of these programs for the development of the hematology workforce, few studies have addressed their characteristics and impact on society. Methods: We performed a comprehensive cross-sectional survey of a 35-year alumni cohort from a hematology academic residency program in Brazil. Results: In total, 86/98 (87.8%) responded to the survey. The mean age at residency completion was 28.5 years, 60.5% of the alumni were women and sixty-four (74.4%) self-declared their skin color as white. Higher rates of parental education attainment and low rates of trainee financial dependence were observed and these patterns were stable over time. While the proportion of trainees from other states increased steadily, the number of hematologists practicing in other states remained stable. Approximately half of the alumni worked both in the private and public sectors, mainly in malignant hematology and in outpatient clinics. Twenty-five percent of the alumni reported prior leadership and teaching positions, mainly as directors of transfusion services. Conclusion: Our results provide data that can be potentially useful for policymakers and curricular development in the planning of strategies concerning the future workforce of hematologists.

VIH/SIDA en embarazadas: evaluación hematológica e inmunológica y peso de sus neonatos / HIV/AIDS in pregnant women: hematological and immunological evaluation and weight of their neonates

Objetivo: Determinar la incidencia de infección por virus de inmunodeficiencia humana y el efectos sobre el peso del neonato, en embarazadas que acuden al Hospital Universitario de Caracas. Métodos: Se incluyeron las gestantes seropositivas para infección por virus de inmunodeficiencia humana. Se practicó Elisa para infección por virus de inmunodeficiencia humana, Webstern blot, hematología y química, linfocitos CD3, CD4 y CD8 por citometría, carga viral, se registró el peso de 204 neonatos y el esquema de tratamiento recibido. Resultados: La frecuencia de infección por virus de inmunodeficiencia humana en gestantes aumentó desde el año 2000; la mayoría ocurre durante el tercer trimestre. El 68,55 % de las gestantes en segundo y tercer trimestre presentaron hemoglobina mayor a 11 g y el 31,45 % tuvo hemoglobina de 7 a 10 g. La relación CD4/CD8 estuvo disminuida. Los niveles de CD4 del segundo trimestre fueron más bajos en pacientes con hemoglobina entre 7 y 10 gramos. Esta relación no se vio en el tercer trimestre, quizás por el grado de supresión viral por el tratamiento; las madres del 95,7 % de los neonatos con bajo peso al nacer recibieron terapia antirretroviral combinada, no hubo neonatos con bajo peso al nacer hijos de madres que recibieron monoterapia. Conclusión: La prevalencia de infección por virus de inmunodeficiencia humana fue 1,6 %. La prevalencia de anemia fue de 31,45 %. La relación CD4/CD8 estaba disminuida. Hubo 11,3 % de neonatos con bajo peso al nacer, en 95,7 % las madres recibieron terapia antirretroviral combinada(AU)

Objective: To determine the incidence of infection by human immunodeficiency virus and the effects on the weight of the newborn, in pregnant women who attend the University Hospital of Caracas. Methods: Seropositive pregnant women for human immunodeficiency virus infection were included. Elisa was performed for human immunodeficiency virus infection, Websternblot, hematology and chemistry, CD3, CD4 and CD8 lymphocytes by cytometry, viral load, the weight of 204 neonates and the treatment scheme received were recorded. Results: The frequency of infection by human immunodeficiency virus in pregnant women has increased since the year 2000; most occur during the third trimester. 68.55% of pregnant women in the second and third trimester had hemoglobin greater than 11 g and 31.45% had hemoglobin between 7 and 10 g. The CD4/CD8 ratio was decreased. Second trimester CD4 counts were lowest in patients with hemoglobin between 7 and 10 grams. This relationship was not seen in the third trimester, perhaps because of the degree of viral suppression by treatment; mothers of 95.7% of low birth weight infants received combination antiretroviral therapy, there were no low birth weight infants born to mothers who received monotherapy. Conclusion: The prevalence of human immunodeficiency virus infection was 1.6%. The prevalence of anemia was 31.45%. The CD4/CD8 ratio was decreased. There were 11.3% of neonates with low birth weight, in 95.7% the mothers received combination antiretroviral therapy(AU)

Evaluation of RET-He values as an early indicator of iron deficiency anemia in pregnant women

Abstract Introduction During pregnancy, women are at an increased risk of developing iron-deficiency anemia. Objective The objective of this study was to assess the diagnostic performance of the reticulocyte hemoglobin equivalent (RET-He) in the early detection of iron-deficiency anemia in a group of pregnant women and to establish a reference range for this parameter in a group of control individuals. Method: A total of 60 patients and 130 control subjects were included in the study. Blood samples collected from the subjects were submitted to a complete blood count and a serum ferritin test and the data were analyzed by comparing the groups and ROC curves. Results The reference range found for the RET-He was between 29.75pg and 38.24pg, with a median of 35pg. The receiver operating characteristic (ROC) curve analysis for the ferritin parameter showed an area under the curve of 0.732 for the RET-He, 0.586 for hemoglobin, 0.551 for the mean corpuscular hemoglobin concentration and 0.482 for the mean corpuscular volume. Conclusion Early diagnosis of iron deficiency anemia in pregnancy is essential to prevent damage to both maternal and fetal health. The RET-He presents an excellent potential as an auxiliary tool for the diagnosis of iron deficiency in pregnant women.

Alternative therapy improves hematological profiles of captive snakes from northeastern Brazil / Efeitos positivos de uma terapia alternativa nos perfis hematológicos de serpentes cativas no nordeste brasileiro

Objective: Evaluate the effects of alternative therapy on the hematological profiles of different families of captive snakes. Methodology: Captive snakes at NUROF-UFC were submitted to a clinical and hematological evaluation before and after applying an alternative treatment, including systematic sunbathing and hydration by soaking bathes twice a week for five weeks. The biometric, clinical, and hematological data were compared by multivariate analysis of variance and investigated for possible causal relationships by general linear models. Results: A significant difference was observed between erythrograms and global leukograms in the three families of snakes evaluated before and after treatment. The significant reduction in the heterophil: lymphocyte ratio in the Family Colubridae after treatment was noteworthy. Discussion: The results were most likely due to stress level reduction by improving thermoregulation and conversion of vitamin D during sunbathing, oral rehydration and refreshing in soaking baths, and general metabolic rates due to physical exercise. Conclusion: The results confirm the initial hypothesis, assuming that a simple but systematic treatment that included sunlight exposure and immersion hydration was efficient in reducing stress rates.

Objetivo: Avaliar a influência de banhos de sol e de imersão em água nos perfis hematológicos de serpentes cativas, antes e após a aplicação deste tratamento alternativo. Metodologia: Serpentes cativas no NUROF-UFC foram submetidas à avaliação clínica e hematológica, depois submetidas ao tratamento alternativo por cinco semanas, sendo novamente avaliadas após. Os dados obtidos foram submetidos à análise estatística multivariada (NPMANOVA e GLM) para investigação de possíveis relações causais entre o tratamento e os perfis hematológicos. Resultados: Foi observada diferença significativa entre os eritrogramas e leucogramas nas três famílias de serpentes avaliadas antes e após o tratamento. Ressalta-se a redução significativa na razão heterófilos:linfócitos na Família Colubridae após o tratamento. Discussão: A diferença estatística deveu-se provavelmente à redução nos níveis de estresse, possibilitada por aquecimento e aumento de conversão da vitamina D durante a exposição solar; reidratação oral e refrescância nos banhos de imersão, e ao recondicionamento pelo exercício físico. Conclusão: Os resultados confirmaram a hipótese inicial, admitindo que um tratamento alternativo, simples mas aplicado sistematicamente, que incluiu exposição à luz solar e hidratação por imersão em água foi eficiente em reduzir as taxas de estresse em serpentes cativas.

Distribution and Drug Sensitivity Analysis of Pathogenic Bacteria Isolated from Patients in Hematology Department / 中国实验血液学杂志

OBJECTIVE@#To investigate the distribution and drug sensitivity of pathogenic bacteria isolated from patients in hematology department, in order to provide evidence for rational use of antibiotics in clinic.@*METHODS@#The distribution of pathogenic bacteria and drug sensitivity data of patients in the hematology department of The First Affiliated Hospital of Nanjing Medical University from 2015 to 2020 were retrospectively analyzed, and the pathogens isolated from different specimen types were compared.@*RESULTS@#A total of 2 029 strains of pathogenic bacteria were isolated from 1 501 patients in the hematology department from 2015 to 2020, and 62.2% of which were Gram-negative bacilli, mainly Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Stenotrophomonas maltophilia and Acinetobacter baumannii. Gram-positive coccus accounted for 18.8%, mainly Coagulase-negative staphylococcus (CoNS) and Staphylococcus aureus. Fungi (17.4%) were mainly candida. The 2 029 strains were mainly isolated from respiratory tract (35.1%), blood (31.8%) and urine (19.2%) specimens. Gram-negative bacilli were the main pathogenic bacteria in different specimen types (>60%). K. pneumoniae, S. maltophilia and A. baumannii were the most common pathogens in respiratory specimens, E. coli, CoNS, K. pneumoniae and P. aeruginosa were common in blood samples, and E. coli and Enterococcus were most common in urine samples. Enterobacteriaceae had the highest susceptibility to amikacin and carbapenems (>90.0%), followed by piperacillin/tazobactam. P. aeruginosa strains had high sensitivity to antibiotics except aztreonam (<50.0%). The susceptibility of A. baumannii to multiple antibiotics was less than 70.0%. The antimicrobial resistance rates of E. coli and K. pneumoniae in respiratory tract specimens were higher than those in blood specimens and urine specimens.@*CONCLUSION@#Gram-negative bacilli are the main pathogenic bacteria isolated from patients in hematology department. The distribution of pathogens is different in different types of specimens, and the sensitivity of each strain to antibiotics is different. The rational use of antibiotics should be based on different parts of infection to prevent the occurrence of drug resistance.

Baseline complete blood count and cell population data as prognostic markers for in-hospital mortality among COVID-19 patients admitted at the Philippine General Hospital from March 2020 to January 2022

INTRODUCTION@#Complete blood count (CBC) and cell population data (CPD) are hematologic parameters used in several clinical scenarios including infection and neoplastic processes. In the setting of COVID-19 infection, there is relative paucity of data in their use as possible prognostic markers.@*OBJECTIVE@#We aim to evaluate the utility of the baseline CBC and CPD as prognostic markers for in-hospital mortality among COVID-19 patients admitted in Philippine General Hospital from March 2020 to January 2022.@*METHODOLOGY@#This is a case-control study. Expired patients served as cases, and recovered patients served as controls. Data from eligible patients including age, sex, admitting COVID diagnosis with severity, final disposition, baseline CBC and CPD results were collected from the hospital medical records and hematology section of the Department of Laboratories. Statistical analyses were done to determine the prognostic value of these parameters for in-hospital mortality.@*RESULTS@#Among the different CBC and CPD parameters, the study shows total white blood cell (WBC) count, absolute neutrophil count (ANC), absolute eosinophil count (AEC), and neutrophil-lymphocyte ratio (NLR) were statistically significant predictors for in-hospital mortality. For total WBC count, at a cut off 9.9 x 10 9 /L, the sensitivity and specificity is 70.9% and 66.2%, respectively. For ANC, at a cut off of 7.3 x 10 9 /L, the specificity is 76.4% and the specificity is 68.2%. At a cut off of 7.62, the NLR shows a sensitivity of 76.4% and specificity of 70.1%. For AEC, at a cut off of 0.006 x 10 9 /L, the sensitivity is 53.3% and the specificity is 87.3%. AEC predicts towards the direction of survival rather than to the direction of in-hospital mortality.@*CONCLUSION@#The total WBC count, ANC, and NLR were statistically significant predictors for in-hospital mortality, while AEC predicts towards the direction of survival. The sensitivities and specificities of the cut off for these parameters were less than ideal. Correlation with clinical and other laboratory parameters is still recommended. For future studies, the authors recommend monitoring CBC and CPD parameters at different time points during the patients’ hospital course.

Profiling of genetic mutations among adult Filipino patients diagnosed with Acute Myeloid Leukemia using fluorescence in situ hybridization from 2014 to 2021: A single-institution study

INTRODUCTION@#Among patients with Acute Myeloid Leukemia (AML), the karyotype at diagnosis is an important prognostic indicator for predicting outcomes. Several studies have been done to identify the most common cytogenetic abnormalities seen in patients in other countries, however, limited studies have been done in our setting.@*OBJECTIVE@#The study aims to determine the most common abnormalities present among patients with AML referred for Fluorescence in situ Hybridization (FISH) at the National Kidney and Transplant Institute.@*METHODOLOGY@#The study included 131 adult patients with a mean age o 46. Fluorescence in situ Hybridization was used to identify the following cytogenetic abnormalities: t(8;21), 11q23 (MLL), 16q22 (CBFB-MYH11), t(15;17) (PML/RARA), t(9;22) (BCR/ABL), 7q31 deletion, and Monosomy 7.@*RESULTS@#FISH was negative in 40% (n=53) of patients. 7q31 deletion is the most frequently identified cytogenetic abnormality among patients with a single abnormality (n=17, 13%) present and is the most frequently identified abnormality among patients with multiple abnormalities (n=26). 7q31 deletion is more frequently observed among patients between the ages 51 to 60 years old and among patients with AML with monocytic differentiation. 22% (n=29) of patients have multiple abnormalities, with the most common abnormalities to occur together are 7q31 deletion and t(8;21) (n=20, 15%). Patients with negative results and patients with multiple cytogenetic abnormalities are commonly seen within the 41 to 50 age group.@*CONCLUSION@# The current study provides a single-institution view of the cytogenetic abnormalities among adult Filipino patients with AML using FISH. Further investigation on the clinical history of these patients, with correlation with other methods, as well as epidemiologic studies are needed to better understand the similarities and differences seen from previously reported incidences.

Hematological and coagulation parameters as predictors of death by Coronavirus disease in hospitalized patients: a Brazilian follow-up study

Abstract This study aimed to evaluate the hematological and coagulation parameters according to the clinical outcomes of coronavirus disease (COVID-19). We analyzed the hematological and coagulation parameters of hospitalized patients with COVID-19 at admission, and two and three weeks during hospitalization. To assess the performance of these parameters in predicting poor outcomes, receiver operating characteristic (ROC) curves were created. We studied 128 patients with COVID-19 (59.2±17.7 years, 56% male). Non-survivors (n=54, 42%) presented significant alterations in hematological and coagulation parameters at admission, such as increased in white blood cells (WBC), neutrophil, and band cell counts, as well as elevated prothrombin time (PT), activated partial thromboplastin time, and D-dimer levels. During follow-up, the same group presented a gradual increase in D-dimer and PT levels, accompanied by a reduction in PT activity, hemoglobin, and red blood cell count (RBC). ROC curves showed that WBC, neutrophil, and band cell counts presented the best area under the curve (AUC) values with sensitivity and specificity of >70%; however, a logistic regression model combining all the parameters, except for RBC, presented an AUC of 0.89, sensitivity of 84.84%, and specificity of 77.41%. Our study shows that significant alterations in hematological and coagulation tests at admission could be useful predictors of disease severity and mortality in COVID-19.

Early integration of palliative care in hematology: an urgency for patients, a challenge for physicians

ABSTRACT Introduction: Early integration between palliative care and other medical specialties in the care of patients with serious illnesses is consolidating itself as good medical practice, based on scientific and ethical evidence. Despite this, palliative care is still not part of the routine care of patients with hematological diseases, even in specialized centers. Objective and method: In this article, we review the benefits and the main barriers described in the literature for early integration of hematology and palliative care. We also point out the challenges encountered in clinical practice, such as end-of-life prognosis assessment in patients with hematological diseases and management of the most common symptoms in hematology. Finally, we review models of integration between palliative care and oncology centers in outpatient and inpatient settings. Results and conclusion: Patients with hematological diseases can greatly benefit from early integration with palliative care, with improvement in symptom control, quality of life, reduction of emotional distress and the development of advanced care directives. It is necessary to make hematologists aware of the benefits of palliative care, provide adequate training for multidisciplinary teams and encourage specific studies of palliative care in patients with hematological diseases.

Relation between anemia and hospitalized older adults' nutritional status / Relação entre anemia e estado nutricional de idosos hospitalizados / Relación entre anemia y estado nutricional de los adultos mayores hospitalizados

Background and Objectives: Malnutrition is frequent in hospitalized older adults, favoring nutritional deficiencies, such as anemia. Several studies have associated anemia with reduced performance in daily activities, which may increase morbidity and mortality. This study aimed to assess the relation between anemia and older adults' nutritional status. Methods: This is a cross-sectional study with hospitalized older adults. Anemia was investigated via hemoglobin. The chosen outcome variables were anemia and hemoglobin and the exposure variables gender, age group, skin color, marital status, education, and nutritional status. Variables were described in absolute and relative frequencies. For statistical analysis, the Chi-square and ANOVA tests were used. Results: Overall, we evaluated 272 hospitalized older adults and fund a 65.1% prevalence of anemia. We associated anemia with age group, malnutrition, and decreased muscle mass. Hemoglobin levels decreased as participants' nutritional status worsened, with malnutrition showing the lowest average. Conclusion: Anemia was associated with nutritional status by the evaluated instruments and we observed a reduction in hemoglobin levels as volunteers' nutritional status worsened. Therefore, research must understand the factors associated with anemia, and healthcare providers should investigate anemic older adults' clinical history anemic to search for its basic cause.(AU)

Justificativa e Objetivos: A desnutrição é frequente em idosos hospitalizados, favorecendo deficiências nutricionais, como a anemia. Diversos estudos associaram a anemia com a redução do desempenho nas atividades diárias, podendo aumentar a morbidade e mortalidade. Este estudo objetivou avaliar a relação entre anemia e estado nutricional de idosos hospitalizados. Métodos: Estudo transversal com idosos hospitalizados. A anemia foi investigada através da hemoglobina. As variáveis desfecho foram a anemia e a hemoglobina; e as variáveis de exposição foram: gênero, faixa etária, cor da pele, situação conjugal, escolaridade e estado nutricional. As variáveis foram descritas em frequência absoluta e relativa. Para análise estatística, utilizou-se os Testes Qui-quadrado e Anova. Resultados: Foram avaliados 272 idosos hospitalizados, nos quais a prevalência de anemia foi de 65,1%. Verificou-se associação dessa condição com a faixa etária, desnutrição e massa muscular diminuída. Os níveis de hemoglobina diminuíram conforme a piora do estado nutricional, sendo que os desnutridos tiveram a menor média. Conclusão: A anemia foi associada com o estado nutricional pelos instrumentos avaliados, também se observou a redução dos níveis de hemoglobina conforme a piora do estado nutricional. Portanto, a compreensão dos fatores associados à anemia é necessária, sendo fundamental que os profissionais de saúde investiguem a história clínica do idoso anêmico em busca de sua causa básica.(AU)
