ABSTRACT Objective: To determine the period during which we should avoid cholecystectomy after endoscopic retrograde cholangiopancreatography. Methods: A retrospective analysis of electronic medical charts of 532 patients undergoing endoscopic retrograde cholangiopancreatography, between March 2013 and December 2017. Results: Approximately one-third of patients underwent the procedure between 4 and 30 days after endoscopic retrograde cholangiopancreatography. The conversion rate was 3.8%. The need for abdominal drainage and the finding of biliary tract injury after surgery were observed in 15.1% and 1.9% of […]

ABSTRACT Objective To follow the expansion of mesenchymal stem cells from umbilical cords by two classic senescence markers, p16 (INK4A) and p21 (CDKN1A), using practical, fast, and less expensive methods than the gold standard Western blotting technique, to evaluate its applicability in the laboratory. Methods Mesenchymal stem cells from umbilical cords were isolated from Wharton’s jelly and, after quality control, morphological and immunophenotypic characterization by flow cytometry, were expanded in culture until coming close to cell cycle arrest (replicative senescence). […]

ABSTRACT Objective To propose a predictive model for the length of stay risk among children admitted to a pediatric intensive care unit based on demographic and clinical characteristics upon admission. Methods This was a retrospective cohort study conducted at a private and general hospital located in the municipality of Sao Paulo, Brazil. We used internal validation procedures and obtained an area under ROC curve for the to build of the predictive model. Results The mean hospital stay was 2 days. […]

ABSTRACT Objective To investigate the possible genes that may be related to the mechanisms that modulate heparanase-1. Methods The analysis was conducted at Universidade Federal de São Paulo, on the data provided by: The Cancer Genome Atlas, University of California Santa Cruz Genome Browser, Kyoto Encyclopedia of Genes and Genomes Pathway Database, Database for Annotation, Visualization and Integrated Discovery Bioinformatics Database and the softwares cBioPortal and Ingenuity Pathway Analysis. Results Using messenger RNA expression pattern of different molecular subtypes of […]

ABSTRACT Objective To translate and make cross-cultural adaptation of NECPAL CCOMS-ICO© tool to Portuguese, and to analyze its semantic validity. Methods A methodological research about NECPAL CCOMS-ICO© tool cross-cultural adaptation, translated from Spanish into Portuguese and measurement of semantic validity. The cross-cultural adaptation process was conducted according to Beaton recommendations, including translation, translation synthesis, back-translation, and analysis of semantic, idiomatic, conceptual, and cultural equivalence of translated and back-translated tool versions, resulting in a pre-final version, which was submitted to a […]

ABSTRACT Objective To characterize the processes of brain death diagnosis and organ donation in a reference trauma center. Methods Observational and cross-sectional study with patients notified with brain death at a reference trauma center. Data were obtained through the collection of medical records and brain death declaration forms. Results One hundred fity-nine patients were notified with brain death, mostly male (82.6%), young adults (97.61%) and victims of brain traumatic injury (93.7%). Median of the total time interval for the diagnosis […]

ABSTRACT Objective To evaluate improvement in quality of life, reduction of uterine volume, and the correlation between these two variables after uterine fibroid embolization. Methods Data on quality of life before and after uterine fibroid embolization were collected from 60 patients using the Uterine Fibroid Symptom – Quality of Life questionnaire. In 40 of these patients, uterine volume information on magnetic resonance imaging examinations performed before and after uterine fibroid embolization was collected, and compared using the nonparametric Wilcoxon test […]

ABSTRACT Objective To develop an informative manual on venous thromboembolism prevention for the lay population and to estimate evidences of content and face validity. Methods A methodological study conducted in three stages. The first stage was the preparation of the manual, followed by content validation with cardiovascular specialists who judged clarity, theoretical relevance and practical pertinence on a 4-point Likert scale. Items with a content validity index ≤0.75 were revised and re-evaluated. The last stage was the face validation by […]

ABSTRACT Objective To assess the level of knowledge of emergency pediatricians on red blood cell transfusions and their reactions. Methods Written survey with emergency pediatricians from a pediatric hospital. Results Less than 20% of pediatricians showed appropriate knowledge on prescribing red blood cells and recognition of transfusion reactions. There was no significant statistical regarding time since graduation and blood transfusion classes in undergraduate studies or during medical residency. Conclusion Pediatricians have insufficient knowledge about red blood cell transfusions and recognition […]

ABSTRACT Objective To investigate the prevalence of palliative sedation use and related factors. Methods An observational study based on data collected via electronic questionnaire comprising 23 close-ended questions and sent to physicians living and working in the state of São Paulo. Demographic data, prevalence and frequency of palliative sedation use, participant’s familiarity with the practice and related motivating factors were analyzed. In order to minimize memory bias, questions addressing use frequency and motivating factors were limited to the last year […]
