ObjectiveThe nursing workload consists of the time spent by the nursing staff to perform the activities for which they are responsible, whether directly or indirectly related to patient care. The aim of this study was to evaluate the nursing workload in an adult intensive care unit at a university hospital using the Nursing Activities Score (NAS) instrument.MethodsA longitudinal, prospective study that involved the patients admitted to the intensive care unit of a university hospital between March and December 2008. The data were collected daily to calculate the NAS, the Acute Physiology and Chronic Health Evaluation (APACHE II), the Sequential Organ Failure Assessment (SOFA) and the Therapeutic Intervention Scoring System (TISS-28) of patients until they left the adult intensive care unit or after 90 days of hospitalization. The level of significance was set at 5%.ResultsIn total, 437 patients were evaluated, which resulted in an NAS of 74.4%. The type of admission, length of stay in the intensive care unit and the patients’ condition when leaving the intensive care unit and hospital were variables associated with differences in the nursing workload. There was a moderate correlation between the mean NAS and APACHE II severity score (r=0.329), the mean organic dysfunction SOFA score (r=0.506) and the mean TISS-28 score (r=0.600).ConclusionWe observed a high nursing workload in this study. These results can assist in planning the size of the staff required. The workload was influenced by clinical characteristics, including an increased workload required for emergency surgical patients and patients who died.
Background: Prostate cancer (PCa) is a heterogeneous disease that lends itself toward numerous therapeutic options depending on its risk stratification. One of the greatest challenges in PCa urologic practice is to select patients who should be referred for biopsy and, for those patients who are diagnosed with cancer, to differentiate between patients with indolent disease from those with an unfavorable prognosis and, to determine ideal patient management and avoid unnecessary interventions. Accordingly, there is a growing body of literature reporting immunohistochemical studies with the objective of determining a prostate cancer prognosis. Among the most frequent biomarkers studied are Ki-67, p53, PTEN, MYC, and ERG. Based on these findings, we systematically reviewed articles that assessed the role of these main prognostic markers in prostate cancer.Methods: Consistent with PRISMA guidelines, we performed a systematic literature search throughout the Web of Science and PubMed Medline databases. We considered all types of studies evaluating the role of Ki-67, p53, PTEN, MYC, and ERG immunohistochemical analysis in prostate cancer until July 2017.Results: We identified 361 articles, 44 of which were summarized in this review. Diagnostically, no single immunohistochemical marker was able to define a tumor as benign or malignant. Prognostically, Ki-67, p53, and MYC were related to the tumor grade given by Gleason score and to the tumor stage (higher levels related to higher tumor grade). Furthermore, Ki-67 was also related to higher PSA levels, shorter disease-free intervals and shorter tumor-specific survival; the latter was also related to p53. The loss of PTEN protein expression showed a higher association with biochemical recurrence and with a worse prognosis, beyond that predicted by the Gleason score and tumor stage. ERG staining also showed a strong association with biochemical recurrence.Conclusion: There are several studies relating immunohistochemical markers with clinical-laboratorial outcomes in prostate cancer, the most frequent being Ki-67, p53, ERG, PTEN, and MYC. However, none of these markers have been validated by literary consensus to be routinely applied in medical practice.
Prostate cancer presents itself in a heterogeneous way with both aggressive and indolent forms. Despite the controversy surrounding its use, prostate-specific antigen screening ultimately leads to a greater number of diagnosed patients. One of the biggest challenges in clinical practice is to select the right patients for biopsy and, among diagnosed patients, to differentiate tumors with an indolent course from those with an unfavorable prognosis, in order to determine the best therapeutic decision for each case, avoiding unnecessary interventions. Currently, several types of biomarkers are available for clinical use in patients with prostate cancer, which include blood-based (prostate-specific antigen, Prostate Health Index®, 4K score®); urine sample-based (PCA3, SelectMDx®, ExoDx Prostate IntelliScore®); and biopsy, transurethral resection, or radical prostatectomy tissue-based (ConfirmMDx®, Oncotype®, Prolaris®, Decipher®). The aim of this review is to provide an overview of the current state of evidence and to highlight recent advances in the evaluation and diagnosis of prostate cancer, with emphasis on biomarkers related to diagnosis and to prognostic evaluation of localized prostate cancer.
Objective: To evaluate the predictive value of positron emission computed tomography or magnetic resonance (PET-CT and PET-MRI) using gallium-68-labeled prostate-specific membrane antigen ( 68 Ga-PSMA) in lymph node involvement in prostate cancer. Methods: A retrospective study comprising 91 patients diagnosed with prostate cancer between 2016 to 2020, who underwent 68 Ga-PSMA PET-CT or PET-MRI for staging before prostatectomy. The patients were divided into Group 1, with 65 patients with satisfactory pathological lymph node analysis, and Group 2, with 91 patients representing the sum of patients with pathological lymph node analysis and those with postoperative prostate-specific antigen within 60 days after surgery. Receiver Operating Characteristic curves were used to assess accuracy of predictive capacity of imaging exams for lymph node involvement. Results: Regarding local clinical staging, the groups showed similar results, and 50% were classified as staging T2a. The accuracy of 68 Ga-PSMA PET-CT for prostate cancer lymph node staging was 86.5% (95%CI 0.74-0.94; p=0.06), with a sensitivity of 58.3% and specificity of 95%. The accuracy of 68 Ga-PSMA PET-MRI was 84.6% (95%CI 0.69-0.94; p=0.09), with a sensitivity of 40% and specificity of 100%. Considering both 68 Ga-PSMA PET-CT and PET-MRI, the accuracy was 85.7% (95%CI 0.76-0.92; p=0.015), with sensitivity of 50% and specificity of 97%. Conclusion: The imaging tests 68 Ga-PSMA PET-CT and PET-MRI were highly accurate to detect preoperative lymph node involvement, and could be useful tools to indicate the need for extended lymph node dissection during radical prostatectomy.
Objective: To describe and compare the number of surgeries, mortality rate, length of hospital stay, and costs of transurethral resection of the prostate and open prostatectomy for the treatment of benign prostatic hyperplasia, between 2008 and 2018, in the Public Health System in São Paulo, Brazil. Methods: Ecological and retrospective study using data from the informatics department of the Brazilian Public Health System database. Procedure codes were "open prostatectomy" and "transurethral resection of the prostate." The outcomes analyzed were compared between transurethral resection of the prostate and open prostatectomy according to the hospital surgical volume and presence or absence of a residency program. Results: A total of 18,874 surgeries were analyzed (77% transurethral resection of the prostate) and overall mortality was not statistically different between procedures. Intermediate and high-volume centers had shorter length of hospital stay than low-volume centers for transurethral resection of the prostate (3.28, 3.02, and 6.58 days, respectively, p=0.01 and p=0.004). Length of hospital stay was also shorter for open prostatectomy in high-volume compared to low-volume centers (4.86 versus 10.76 days, p=0.036). Intrahospital mortality was inversely associated with surgical volume for transurethral resection of the prostate. Centers with residency program had shorter length of hospital stay considering open prostatectomy and less mortality regarding transurethral resection of the prostate. Open prostatectomy was 64% more expensive than transurethral resection of the prostate. Conclusion: The findings suggest the importance of investing in specialized centers, which could be potential referral centers for surgical cases.
RESUMO Introdução: o tratamento do câncer de adrenal benigno (hormonalmente ativo ou não funcional) e maligno inclui a adrenalectomia. A experiência dos cirurgiões e a cirurgia realizada por cirurgiões de alto volume foram associadas a menos complicações e menor custo. O objetivo do estudo foi descrever e comparar o número de cirurgias, a taxa de mortalidade e o tempo de internação para adrenalectomias realizadas entre 2008 e 2019 na rede pública de saúde de São Paulo. Métodos: trata-se de um estudo ecológico. Os dados foram coletados da Plataforma TabNet do Departamento de Informática do Sistema Único de Saúde. Os hospitais foram divididos em três subgrupos de acordo com o volume cirúrgico e hospitais com e sem programa de residência médica em Urologia. Os resultados foram comparados entre os grupos. Resultados: no período estudado, 943 adrenalectomias foram realizadas em São Paulo. As taxas de mortalidade durante a internação de acordo com o volume cirúrgico hospitalar foram: não foram relatados óbitos em hospitais de baixo volume; 0,015% em hospitais de volume intermediário e 0,004% em alto volume. O tempo médio de permanência na UTI foi de 1,03 dias nos hospitais de baixo volume; 2,8 nos de médio volume e 1,12 nos de alto volume (análise entre centros de médio e alto volume com significância estatística, p=0,016). Conclusão: as taxas de mortalidade foram muito baixas em todos os grupos. A permanência na UTI foi menor em centros de alto volume do que em centros de volume intermediário.
Objective:To analyze the characteristics of public health services related to radical prostatectomy, according to hospital volume of surgeries and stratified as academic and nonacademic centers. Methods: An ecological study was conducted using a database available in TabNet platform of the Unified Health System Department of Informatics. Number of surgeries, length of hospital stay, length of stay in intensive care unit, in-hospital mortality rate, and cost of hospitalization were evaluated. The hospitals were divided into three subgroups according to surgery volume (tercile), and results were compared. The same comparisons were made among academic and non-academic centers. We considered academic centers those providing Urology residency program. Results: A total of 11,259 radical prostatectomies were performed in the city of São Paulo between 2008 and 2018. We observed a significant trend of increase in radical prostatectomies for treating prostate cancer over the years (p=0.007). The length of stay in intensive care unit, and number of deaths were not statistically different among centers with diverse surgery volume, nor between academic and non-academic centers. However, length of hospital stay was significantly shorter in academic centers (p=0.043), while cost of hospitalization was significantly higher in high-volume center compared to low-(p<0.001) and intermediatevolume centers (p<0.001). Conclusion: Length of hospital stay for radical prostatectomies performed in public services in the city of São Paulo was shorter in academic centers, whereas hospitals with a high volume of surgeries showed greater cost of hospitalization.
