ABSTRACT

The free acidity of bracatinga honeydew honey (BHH) was monthly monitored over short-term storage (four months) until all the samples exceeded 50 mEq kg-1 - the maximum value allowed by the international regulatory honey standards. In addition, BHH quality was also investigated through moisture content, water activity, electrical conductivity, pH, 5-hydroxymethylfurfural, and aliphatic organic acids (AOA) analyses. According to our results, most of the parameters investigated presented significant differences during the short storage period studied; however, the quality parameters (except acidity) did not exceed the limits established by the international regulatory honey standards. Therefore, the high free acidity observed in the BHH samples did not affect its quality. Moreover, the total AOA concentration decreased as the free acidity increased, indicating that the high acidity is not related to postharvest fermentation. Since all BHH samples exceeded the established limit of 50 mEq kg-1 after four months of storage (up to 62.7 mEq kg-1), this data corroborates that this type of honey does not comply with the regulatory honey standards, which represents an obstacle to its commercialization. Therefore, our data reinforce the need for a future reassessment of the international regulatory honey standards regarding the free acidity limit for BHH. In this sense, taking together all the studies developed by our research group since 2014, a new free acidity value of 65 mEq kg-1 is proposed, which may discourage fraud practices and negative impacts on the BHH beekeeping chain.

ABSTRACT

OBJECTIVE: To analyze the characteristics of public health services related to radical prostatectomy, according to hospital volume of surgeries and stratified as academic and non-academic 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 intermediate-volume 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.

ABSTRACT

INTRODUCTION: treating benign (hormonally active or nonfunctional) and malignant adrenal cancer includes adrenalectomy. The expertise of surgeons and surgery performed by high-volume surgeons were associated with fewer complications and lower cost. We aimed to describe and compare the number of surgeries, mortality rate, and length of hospital stay for adrenalectomies performed between 2008 and 2019 in the public health system of São Paulo. METHODS: this was an ecological study. The data were collected using the TabNet Platform of the Unified Health System Department of Informatics. Outcomes analyzed included the number of surgeries performed, mortality rate during hospital stay, and length of hospital stay. Public hospitals in Sao Paulo were divided into three subgroups according to the surgical volume of adrenalectomies performed as well as hospitals with and without a residency program in Urology, and the results were compared among them. RESULTS: a total of 943 adrenalectomies were performed in Sao Paulo between 2008 and 2019. Mortality rates during hospital stay according to hospital surgical volume were no reported deaths in low-volume, 0.015% in intermediate-volume, and 0.004% in high-volume hospitals. The average length of the ICU stay was 1.03 days in low-volume, 2.8 in intermediate-volume, and 1.12 in high-volume hospitals (analysis between intermediate and high volume centers with statistical significance, p=0.016). CONCLUSIONS: despite no statistically significant differences among the groups analyzed, mortality rates were very low in all groups. ICU stay was shorter in high-volume centers than in intermediate-volume centers.

ABSTRACT

OBJECTIVE: The aim of this study was to describe and compare the outcomes and indirect costs of oncological radical (RN) and partial nephrectomies (PN) in hospitals from the São Paulo public health system, Brazil. MATERIALS AND METHODS: An ecologic retrospective study was performed from 2008 to 2019, using the TabNet Platform of the Brazilian Unified Health System Department of Informatics. Hospitals were classified according to volume of surgeries (low and high-volume, and also into four quartiles according to volume of surgeries), and with or without medical residency program in urology. The results were compared between groups. RESULTS: In the period analyzed were performed 2.606 RN in 16 hospitals. Data available for PN ranged only from 2013-2019 and included 1.223 surgeries comprising 15 hospitals. Overall mortality rates were 0.41% for PN and 2.87% for RN. The length of hospital stay was significantly higher in low-volume hospitals for both RN and PN (8.97 vs. 5.62 days, p = 0.001, and 7.75 vs. 4.37 days, p = 0.001, respectively), and also for the RN in hospitals without residency program in Urology (9.37 vs. 6.54 days, p = 0.03). When the volume of surgeries was divided into four quartiles, the length of hospital stay and ICU hospitalization days were significantly higher in the first quartile hospitals for RN (p = 0.016) and PN (p = 0.009), respectively. The mortality rates and indirect costs were not different considering PN and RN in the different types of hospitals. CONCLUSIONS: The length of hospital stay was significantly lower for both PN and RN in high-volume hospitals, and also for RN in hospitals with residency program in Urology.

ABSTRACT

BACKGROUND: Active surveillance (AS) is the preferred treatment for patients with very low-and low-risk prostate cancer (PCa), but it is underperformed worldwide. This study aimed to report knowledge, attitudes, and practices (KAP) of AS for PCa among urologists in Brazil. METHODS: This cross-sectional study used a questionnaire with 50 questions divided into participant characteristics, knowledge regarding inclusion criteria for AS, follow-up, intervention triggers, acceptance, and practice for an index patient. Data analysis comprises absolute and relative frequencies of the variables. After that, a logistic regression was performed in order to verify possible patterns of answers provided by the respondents in the index patient questionnaire. RESULTS: Questionnaires were sent through the SurveyMonkey® platform to 5,015 urologists using email addresses and through social media. A total of 600 (12%) questionnaires returned and 413 (8.2%) were completed and included in the analysis. Only 53% of urologists adopt AS for low- and very-low-risk PCa. Inclusion criteria were patients with age > 50 years (32.2%), prostate specific antigen (PSA) < 10 ng/mL (87.2%), T1 clinical stage (80.4%), Biopsy Gleason score ≤ 6, positive cores ≤ 2 (44.3%), positive core involvement < 50% (45.3%), and magnetic resonance imaging findings (38.7%). The PSA doubling time was still used by 60.3%. Confirmatory biopsy (55.9%), PSA level (36.6%), and digital rectal examination (34.4%) were considered by most urologists for follow-ups. Patient preference (85.7%), upgrade of Gleason score (73.4%), and increased number of positive cores (66.8%) were associated with conversion to definitive treatment. In an index patient, non-acceptance and active treatment request were the most cited reasons for not performing AS. CONCLUSION: There is significant variability in the KAP of AS in Brazil, which indicates the need to reinforce AS, its inclusion and follow-up criteria, and the benefits for physicians and the general population. TRIAL REGISTRATION: Not applicable.

ABSTRACT

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.

ABSTRACT

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 (68Ga-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 68Ga-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 68Ga-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 68Ga-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 68Ga-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 68Ga-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.

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.

ABSTRACT

PURPOSE OF REVIEW: To compare laparoscopic partial nephrectomy (LPN) and robot-assisted partial nephrectomy (RAPN) performed in two European tertiary centers using the classic optimal surgical definition - "MIC" - and a new optimal surgical definition: the "Novel TRIFECTA" (NT) concept. We sought to strengthen the PN evidence and to test the NT's performance. RECENT FINDINGS: The study population comprehended 505 cases of localized kidney cancer from two tertiary centers between 2012 and 2019. The NT achievement was higher in the RAPN group when compared to LPN (70.5 vs. 87.4%; p = 0.004), while no differences were found when considering the MIC criteria. Also, a similar high-grade complications rate (Clavien-Dindo > III) and operative time (105 min vs. 100 min; p = NS) were found. In the multivariable regression, the RAPN approach was a predictor of NT achievement (OR 2.45; p = 0.008). NT achievement was higher in the RAPN group, while similar results were found when evaluating the MIC criteria. The NT definition could be more sensitive to the individual-specific responses related to the PN.

ABSTRACT

BACKGROUND: The Expanded Prostate Index Composite for Clinical Practice (EPIC-CP) is a short version of the original EPIC, developed to facilitate the instrument's use in routine care. This study aimed to validate the EPIC-CP Portuguese version, and evaluate its role in presenting early functional outcomes of surgically treated prostate cancer patients at a Latin American referral center. METHODS: The EPIC-CP was self-administered prospectively and individually by all localized prostate cancer patients, before and after robotic-assisted radical prostatectomy, from March 2017 to June 2018 at a single institution. For validation, we used the Cronbach's alpha coefficient to evaluate internal consistency. The EPIC-CP domains were compared before surgery, and 6 months and 12 months after surgery. Statistical analyses were performed using the student's t test, and Wilcoxon and Friedman tests, with p values < 0.05 considered significant. RESULTS: One hundred and fifty two patients answered the EPIC-CP. The patients had a median age of 62.7 (± 8.5) years and prostate specific antigen level of 6.3 (± 4.6) ng/ml. The Cronbach's alpha varied from 0.75 to 0.77 for all domains with good internal consistency, except for the "vitality/hormonal" domain, which had a score of 0.35. The domain evolution for the preoperative and 6-month postoperative groups revealed that the domains related to urinary continence and bowel worsened, and were increased during the first 6 months; however, this variation had no obvious clinical implications, and the irritative symptoms improved. Regarding the sexual domain, the scores worsened, and also increased over the first 6 months. The results of the confirmatory factor analysis were robust, with an explained variance of 0.951 and covariance of 0.929. CONCLUSIONS: The Portuguese version of the EPIC-CP is a reliable and valid questionnaire for postoperative patients, and very useful to improve the knowledge of the early functional outcomes of men treated for prostate cancer.

ABSTRACT

INTRODUCTION: To evaluate the clinical dilemma of men with surgical indication due to benign prostatic enlargement (BPE) and concomitant elevated PSA, we analysed if multiparametric magnetic resonance imaging (mpMRI) could safely prescind the prostate biopsy. METHODS: Forty men with surgical indication due to BPE and concomitantly elevated PSA levels were prospectively enrolled and retrospectively analysed. All patients underwent 1.5 Tesla mpMRI prior to TRUS-guided biopsies. In cases where mpMRI was PIRADS 3 with focal lesions, PIRADS 4 or PIRADS 5, additional fragments were obtained with the fusion guided technique. Biopsy histopathological results were used as the standard of reference. Two scenarios were evaluated: scenario 1, considering mpMRI PIRADS 1 and 2 as negative; and scenario 2, considering PIRADS 1, 2 and 3 as negative. Clinically significant prostate cancer (CsPCa) was defined as ISUP ≥ 2. RESULTS: Median age was 68 years, median PSA was 9.41 (6.40-19.54) and median prostatic volume was 116.5 cc (IQR 86.5-155). Scenario 1 mpMRI sensitivity, specificity, PPV, NPV and accuracy for any prostate cancer on prostate biopsy was 76.9%, 63%, 50%, 85% and 67.5%. For csPCa, they were 87.5%, 59.4%, 35%, 95% and 65%, respectively, for the same measures. Scenario 2 the sensitivity, specificity, PPV, NPV and accuracy of mpMRI for any prostate cancer on prostate biopsy was 53.8%, 96.3%, 87.5%, 81.3% and 82.5%. For csPCa, they were 75%, 93.8%, 75%, 93.8% and 90%, respectively, for the same measures. CONCLUSION: Prostate mpMRI may prevent unnecessary biopsies in patients with elevated PSA and surgical indications due to BPE, given its high negative predictive value.

ABSTRACT

INTRODUCTION AND OBJECTIVE: This study aims to evaluate safety and efficacy of different endoscopic enucleation of the prostate (EEP) techniques, by comparing laser (L-EEP) and non-laser (NL-EEP) procedures; and EEP versus other endoscopic non-enucleation (ENE) surgeries for benign prostatic enlargement (BPE). METHODS: A systematic literature review was performed for randomized clinical trials (RCT) that compared different endoscopic treatments for BPE, between 1982 and 2018. Two analyses were performed: (1) EEP versus ENE; and (2) L-EEP versus NL-EEP. Efficacy was assessed using perioperative data (removed tissue volume, operation time (OT), catheterization time, length of hospital stay); and functional outcomes [IPSS, IIEF-5, maximum flow rate (Qmax), postvoid residual volume (PVR), quality of life (QoL)]. Safety was assessed through complications (Hb and sodium decrease, transfusion rate). Meta-analyses were performed using RevMan® 5.3. RESULTS: Out of 35 RCTs (4066 patients), 31 (3909 patients) evaluated EEP versus ENE, and 4 (327 patients) evaluated L-EEP versus NL-EEP. EEP presented greater Qmax. Also, EEP presented less catheterization time, length of hospital stay, Hb decrease, transfusion rate. OT and bladder injury were greater with EEP. There were no significant differences between other items. L-EEP removed more tissue volume, with a smaller drop in serum Hb. There were no significant differences in other perioperative data, functional outcomes, complications. CONCLUSIONS: EEP and ENE are effective and safe for treating BPE. Perioperative data favors EEP. Statistical differences, with questionable clinical significance in functional outcomes and complication rates were encountered. L-EEP provides greater tissue removal and smaller Hb decrease then NL-EEP, with similar functional profiles.
