Abstract Introduction The Acute Leukemia-European Society for Blood and Marrow Transplantation (AL-EBMT) risk score was recently developed and validated by Shouval et al. Objective To assess the ability of this score in predicting the 2-year overall survival (OS-2), leukemia-free survival (LFS-2) and transplant-related mortality (TRM) in acute leukemia (AL) adult patients undergoing a first allogeneic hematopoietic stem cell transplant (HSCT) at a transplant center in Brazil. Methods In this prospective, cohort study, we used the formula published by Shouval et al. to calculate the AL-EBMT score and stratify patients into three risk categories. Results A total of 79 patients transplanted between 2008 and 2018 were analyzed. The median age was 38 years. Acute myeloid leukemia was the most common diagnosis (68%). Almost a quarter of the cases were at an advanced stage. All hematopoietic stem cell transplantations (HSCTs) were human leukocyte antigen-matched (HLA-matched) and the majority used familial donors (77%). Myeloablative conditioning was used in 92% of the cases. Stratification according to the AL-EBMT score into low-, intermediate- and high-risk groups yielded the following results: 40%, 12% and 47% of the cases, respectively. The high scoring group was associated with a hazard ratio of 2.1 (p= 0.007), 2.1 (p= 0.009) and 2.47 (p= 0.01) for the 2-year OS, LFS and TRM, respectively. Conclusion This study supports the ability of the AL-EBMT score to reasonably predict the 2-year post-transplant OS, LFS and TRM and to discriminate between risk categories in adult patients with AL, thus confirming its usefulness in clinical decision-making in this setting. Larger, multicenter studies may further help confirm these findings.

Abstract Background ABO blood group incompatibility between donor and recipient is associated with a number of immunohematological complications, but is not considered a major contraindication to allogeneic hematopoietic stem cell transplantation. However, available evidence from the literature seems to be conflicting as to the impact of incompatibility on overall survival, event-free survival, transplant-related mortality, graft-versus-host disease, and time to neutrophil and platelet engraftment. Methods This single-center, prospective, cohort study included patients with hematological malignancies who underwent a first allogeneic hematopoietic stem cell transplantation between 2008 and 2014. Patients receiving umbilical cord blood as the stem cell source were excluded from this analysis. The impact of ABO incompatibility was evaluated in respect to overall survival, event-free survival, transplant-related mortality, acute graft-versus-host disease and engraftment. Results A total of 130 patients were included of whom 78 (60%) were males. The median age at transplant was 36 (range: 2–65) years, 44 (33%) presented ABO incompatibility, 75 (58%) had acute leukemia, 111 (85%) had a related donor, 100 (77%) received peripheral blood hematopoietic stem cells as graft source and 99 (76%) underwent a myeloablative conditioning regimen. There was no statistically significant association between ABO incompatibility and overall survival, event-free survival, transplant-related mortality, grade II–IV acute graft-versus-host disease, neutrophil or platelet engraftment in multivariate analysis. Conclusion These results show that ABO incompatibility does not seem to influence these parameters in patients undergoing allogeneic hematopoietic stem cell transplantation.

OBJECTIVE: The aim of this study was to analyze the characteristics and infectious complications of neutropenic patients in a referral hospital. METHODS: A cross-sectional study was carried out between April and September 2008, which enrolled all neutropenic patients identified by daily blood counts in the Universidade Federal de Minas Gerais. Demographic data and information on infections were obtained from the Hospital Infection Control Committee. Statistical analysis was performed using the Statistical Package for Social Sciences. RESULTS: One hundred and sixteen patients were followed up during 129 hospitalizations. The patients had a mean age of 48.7 years old. Sixty-four (55.2%) patients were male and 25 (21.6%) died during the follow-up. In 97 (75.2%) of the hospitalizations, patients had episodes of febrile neutropenia. Patients classified as low-riskhad a mortality rate of 16.2% (n = 12) vs. 39.1% (n = 9) among high-risk patients (p-value = 0.02). The death rate of the patients who had been submitted to hematopoietic stem cell transplantation was 13.5% (n = 5)vs. 26.7% (n = 16) among patients not submitted to transplantation (p-value = 0.13). Of the 155 infections diagnosed, 45.5% were defined as clinically documented. The etiological agent most frequently isolated was Escherichia coli and the main topography reported was bloodstream infections. The most used antimicrobial agents were cefepime, vancomycin and fluconazole. Approximately 24% of patients evolved with impaired renal function during hospitalization. CONCLUSION: Most reported infections in neutropenic patients were defined as clinically documented, which shows the importance of suspicion in patients without specific signs and symptoms for early diagnosis and the need for the classification of risk for timely interventions.

The Intensive Care Units represent an important and indispensable part of the modern medicine, for offering services to critically sick patients, using specialized human resources and advanced technology. In this study it was aimed to determine the incidence of the nosocomial infection, its possible relationship with the occurrence of the colonization by resistant microorganisms, the main agents of that colonization, and the mortality rate in that unit. It was a prospective and descriptive study, from August 2005 to July 2006. The data were collected from medical records and consultation to the microbiologic database. The global infection rate was 23,8%, the colonization for resistant microorganisms contributed to the development of infection (RR=6,8 [4,8-9,6], p <0,05), the resistant pathogens more prevalent were Pseudomonas aeruginosa and Acinetobacter baumannii. The mortality rate was 10,8%, and of these, 23 patients (37,1%) died after the diagnosis of nosocomial infection. Those results reinforce the need of efforts addressed to the control of the infection and of the bacterial resistance, subsidizing reflections in front of the adoption of measures such as the use of individual protection equipments, the invasive procedures, the handwashing, and the permanent education of the multiprofissional assistance team.

Os Centros de Terapia Intensiva representam uma importante e indispensável parte da medicina moderna, por prestar atendimento a pacientes criticamente enfermos utilizando recursos humanos especializados e tecnologia avançada. Objetivou-se neste estudo determinar a incidência da infecção hospitalar, sua possível relação com a ocorrência da colonização por microrganismos resistentes, os principais agentes dessa colonização e a taxa de mortalidade nesta unidade. Tratou-se de um estudo prospectivo e descritivo entre agosto de 2005 a julho de 2006. Para a coleta de dados realizou-se a leitura de prontuários e consulta ao banco de dados microbiológicos, entre outros. A taxa global de infecção foi de 23,8%, a colonização por microrganismos resistentes contribuiu para o desenvolvimento de infecção (RR=6,8 [4,8-9,6], p<0,05), cujos patógenos resistentes mais prevalentes foram Pseudomonas aeruginosa e Acinetobacter baumannii. A taxa de mortalidade foi de 10,8% e destes, 23 pacientes (37,1%) faleceram após o diagnóstico de infecção hospitalar. Tais resultados reafirmam a necessidade de esforços direcionados ao controle da infecção e da resistência bacteriana subsidiando reflexões frente à adoção de medidas tais como uso de equipamentos de proteção individual, procedimentos invasivos, higienização das mãos e educação permanente da equipe assistencial multiprofissional.

OBJETIVO: A infecção do sítio cirúrgico constitui um grave problema dentre as infecções hospitalares por sua incidência, morbidade e mortalidade. Devido ao curto período de internação, a maioria dessas infecções se manifesta após a alta hospitalar, sendo subnotificada quando não há o seguimento do paciente cirúrgico. Programas de vigilância específicos do paciente após a alta são considerados fundamentais para controlar as infecções. O objetivo do estudo foi determinar a incidência de infecção do sítio cirúrgico e comparar sua freqüência durante a internação e após a alta. MÉTODOS: Realizou-se um estudo epidemiológico, tipo coorte, em um hospital universitário, com acompanhamento durante o período de internação e no seguimento pós-alta hospitalar, de 504 pacientes que se submeteram à cirurgia do aparelho digestivo no primeiro semestre de 2000. RESULTADOS: Das 504 cirurgias realizadas no período do estudo, 398 (79,0%) dos pacientes retornaram ao ambulatório de egressos. Do total de infecções do sítio cirúrgico diagnosticadas, a maioria (62,9%) foi notificada no ambulatório de egressos, sendo 88,0% superficiais, e 67,0% notificadas até o sétimo dia após a alta. CONCLUSÕES: Comprovou-se a importância do seguimento pós-alta para a obtenção de dados fidedignos sobre as infecções do sítio cirúrgico devido à manifestação tardia na maioria dos casos, levando a subnotificação quando o seguimento do paciente é realizado somente durante a internação.

OBJECTIVE: Surgical wound infection (SWI) is a serious hospital infection due to its incidence, morbidity and mortality. Because of the short hospital stay, the majority of SWI appears post-discharge, and its incidence is often underreported when there is no follow-up of the surgical patient post discharge. The need of a surveillance system for surgical patient after discharge is critical for infection control. The study objective was to determine the incidence of SWI in surgical patients and to compare the frequency of SWI diagnosed in-hospital and after discharge. METHODS: A prospective cohort study was carried out in a university hospital. Patients admitted to the general surgery unit (504) and underwent digestive tract surgery in the first semester of the year 2000 were followed up during their hospital stay and after discharge. RESULTS: Of 504 surgical patients, 398 (79.0%) returned to follow up in the post discharge outpatient clinic. Of the total surgical wound infections diagnosed, most (62.9%) was detected in the post discharge outpatient clinic, and 88% of SWI diagnosed were classified as superficial, and 67% reported up to day 7 after discharge. CONCLUSIONS: This study showed the importance of following up surgical patients after discharge to achieve reliable incidence data on surgical wound infection because of the late occurrence of infection in the majority of cases, which results in underreporting when the patient is followed up only during the hospital stay.
