RESUMO
Biosurfactants (BSFs) are molecules produced by microorganisms from various carbon sources, with applications in bioremediation and petroleum recovery. However, the production cost limits large-scale applications. This study optimized BSFs production by Bacillus velezensis (strain MO13) using residual glycerin as a substrate. The spherical quadratic central composite design (CCD) model was used to standardize carbon source concentration (30 g/L), temperature (34 °C), pH (7.2), stirring (239 rpm), and aeration (0.775 vvm) in a 5-L bioreactor. Maximum BSFs production reached 1527.6 mg/L of surfactins and 176.88 mg/L of iturins, a threefold increase through optimization. Microbial development, substrate consumption, concentration of BSFs, and surface tension were also evaluated on the bioprocess dynamics. Mass spectrometry Q-TOF-MS identified five surfactin and two iturin isoforms produced by B. velezensis MO13. This study demonstrates significant progress on BSF production using industrial waste as a microbial substrate, surpassing reported concentrations in the literature.
RESUMO
INTRODUCTION AND HYPOTHESIS: The objective was to assess whether telemedicine-based follow-up is equivalent to office-based follow-up in the early postoperative period after routine synthetic midurethral sling placement. METHODS: This is a prospective, international, multi-institutional, randomized controlled trial. Patients undergoing synthetic midurethral sling placement were randomized to 3-week postoperative telemedicine versus office-based follow-up. The primary outcome was the rate of unplanned events. Secondary outcomes included patient satisfaction, crossover from telemedicine to office-based follow-up, and compliance with 3- to 5-month office follow-up. RESULTS: We included 238 patients (telemedicine: 121 vs office: 117). No differences in demographics or medical comorbidities were noted between the study groups (p = 0.09-1.0). No differences were noted in unplanned events: hospital admission, emergency department visit, or unplanned office visit or call (14% vs 12.9%, p = 0.85) or complications (9.9% vs 8.6%, p = 0.82). Both groups were equally "very satisfied" with their surgical outcomes (71.1% vs 69%, p = 0.2). Telemedicine patients were more compliant with 3- to 5-month office follow-up (90.1% vs 79.3%, p = 0.04). CONCLUSIONS: After synthetic midurethral sling placement, telemedicine follow-up is a safe patient communication option in the early postoperative period. Telemedicine patients reported no difference in satisfaction compared with office-based follow-up but had greater compliance with 3- to 5-month follow-up.

The mainstays of treatment for colorectal liver metastases (CRLMs) are surgery and chemotherapy. Chemotherapeutic benefits of tumor shrinkage and systemic control of micrometastases are in part counterbalanced by chemotoxicity that can modify the liver parenchyma, jeopardizing the detection of CRLM. This review addresses the clinical decision-making process in the context of radiographic and pathologic responses, the preoperative imaging workup, and the approaches to the liver for CRLM, which disappear after systemic chemotherapy.

OBJECTIVE: This study assessed the possible existence of genotype by environment interactions for milk, fat and protein yields in Holstein cattle raised in one of the most important milk production basins in Brazil. METHODS: Changes in the genetic parameters and breeding values were evaluated for 57,967 animals from three distinct regions of southern Brazil, divided according to differences in climate. The genotype by environment interaction was determined by genetic correlations between regions, estimated by the restricted maximum likelihood, considering the animal model. Bull rankings were investigated to verify the ratio of coincident selected animals between regions for each trait. RESULTS: The estimates of heritability coefficients were similar between two regions, but were lower in the third evaluated area, for all traits. Genetic correlations between regions were high, ranging from 0.91 to 0.99 for milk, fat and protein yields, representing the absence of a genotype by environment interaction for productive traits. The percentage of selection error between regions for the top 10% of animals ranged from 0.88% to 2.07% for milk yield, 0.99% to 2.46% for fat yield and 0.59% to 3.15% for protein yield. CONCLUSION: A slight change in genotype between areas was expected since no significant genotype by environment interactions were identified, facilitating the process of selecting Holstein cattle in southern Brazil.
RESUMO
BACKGROUND: Overall survival (OS) is a critical endpoint in adjuvant trials but requires long durations to events and significant patient resources. In the current study, the authors assessed whether disease-free survival (DFS) can be an early clinical surrogate for OS in the adjuvant setting for localized renal cell carcinoma (RCC). METHODS: Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, the authors performed a systematic literature review of PubMed and the American Society of Clinical Oncology, European Society for Medical Oncology, and ClinicalTrial.gov Web sites (1996-2016). Inclusion in the current study required randomized controlled trials (RCTs) of adjuvant systemic therapy for localized RCC after nephrectomy with ≥3 years of outcomes data. Data regarding hazard ratios (HRs) and 5-year event-free rates from Kaplan-Meier estimates were extracted. A trial-level meta-analysis correlated estimates of 5-year DFS and 5-year OS as well as treatment effects (HRs) on these endpoints, weighted by the number of DFS events. R-squared ≥ 0.7 was prespecified as being indicative of a strong correlation and the potential for surrogacy. RESULTS: Thirteen RCTs encompassing 6473 patients who were treated with a variety of systemic therapies met eligibility. Only a modest correlation was observed between 5-year DFS and 5-year OS rates (R-squared, 0.48; 95% confidence interval, 0.14-0.67) and between treatment effects as measured by DFS and OS HRs (R-squared, 0.44; 95% confidence interval, 0.00-0.69). CONCLUSIONS: Across RCTs of adjuvant systemic therapy for localized RCC, there was no strong correlation noted between 5-year DFS and 5-year OS rates or between treatment effects on these endpoints. These results highlight the need to identify alternative and more rapid clinical or biologic endpoints to hasten drug development and improve clinical outcomes.

BACKGROUND: To the authors' knowledge, outcomes and prognostic tools have yet to be clearly defined in patients with metastatic renal cell carcinoma (mRCC) who are treated with immuno-oncology (IO) checkpoint inhibitors (programmed death-ligand 1 [PD-L1] inhibitors). In the current study, the authors aimed to establish IO efficacy benchmarks in patients with mRCC and update patient outcomes in each International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) prognostic class. METHODS: A retrospective analysis was performed using the IMDC database with data from 38 centers. It included patients with mRCC who were treated with ≥1 line of IO. Overall response rates (ORRs), duration of treatment (DOT), and overall survival (OS) were calculated. Patients were stratified using IMDC prognostic factors. RESULTS: A total of 687 patients (90% with clear cell and 10% with non-clear cell) were included. The ORR was 27% in evaluable patients (461 patients). In patients treated with first-line nivolumab and ipilimumab (49 patients), the combination of PD-L1 inhibitor and vascular endothelial growth factor inhibitor (72 patients), and PD-L1 inhibitor (51 patients), the ORR was 31%, 39%, and 40%, respectively, and the median DOT was 8.3 months, 14.7 months, and 8.3 months, respectively. The ORR for second-line, third-line, and fourth-line nivolumab was 22%, 24%, and 26%, respectively. The median DOT was 5.7 months, 6.2 months, and 8.3 months, respectively, in the second-line, third-line, and fourth-line settings. When segregated into IMDC favorable-risk, intermediate-risk, and poor-risk groups, the median OS rates for the first-line, second-line, third-line, and fourth-line treatment settings were not reached (NR), NR, and NR, respectively (P = .163); NR, 26.7 months, and 7.4 months, respectively (P < 0. 0001); 36.1 months, 28.2 months, and 11.1 months, respectively (P = .016); and NR, NR, and 6.7 months, respectively (P = .047). CONCLUSIONS: The ORR was not found to deteriorate from the first-line to the fourth-line of IO therapy. In the second line through fourth line, the IMDC criteria appropriately stratified patients into favorable-risk, intermediate-risk, and poor-risk groups for OS.

Treatment of orbital fractures involves restoration of lost bone anatomy and orbital volume. Among the materials used for this purpose, the titanium mesh is widely used due to its effectiveness and low complication rate related to distortion especially in non-traumatic events. This study shows an atypical and late complication involving the deformation of the titanium mesh used during reconstruction of the orbital floor in a patient with orbital zygomatic complex fracture 5 months after the procedure and without traumatic etiology.

Necrotizing fasciitis (NF) is a severe bacterial infection with rapid and aggressive progression. The infection generally affects individuals with comorbid conditions that lead to immunologic and microvascular deficiencies. It is characterized by necrosis of tissues, mainly in the extremities, trunk, and perineum, and is rarely found in the head and neck. This case report describes the course of NF in a 55-year-old man, highlighting diagnosis, surgical treatment, drug therapy, and supportive measures. The patient, who had chronic alcoholism, systemic arterial hypertension, a smoking habit, and decompensated diabetes (glucose level of 490 mg/dL), was admitted to the hospital with a volume increase in the cervical and thoracic areas with a duration of about 7 days. He presented with fever, dyspnea, and inflammatory signs bilaterally in the submandibular, submental, and superior thoracic regions as well as severe trismus. The patient underwent a surgical procedure to drain the infectious process and to place drains. The patient developed cutaneous necrosis in the cervical and superior thoracic regions, diagnosed as NF. Surgical debridement of all affected tissue was performed. After resolution of the infection, the patient underwent skin grafting with a satisfactory outcome.

Endodontic treatment in severely calcified canals is always a challenging task because it can result in accidents such as deviations or perforations. Recently, guided endodontics has become an alternative approach for pulp canal calcification, facilitating the location of root canals more predictably through the combined use of cone-beam computed tomographic imaging, oral scanning, and endodontic access guides. Although several reports have shown that guided endodontics is safer, faster and can be performed without an operating microscope and by less experienced operators, the technique has limitations, and iatrogenesis may occur. This article describes the limitations of static-guided endodontics and possible causes of failures. In the present case, not fixing the guide to the bone and inaccuracies generated by manually performing mesh merger software led to root perforation. Endodontic microsurgery was effective in resolving this case and should be considered the treatment of choice when guided endodontics cannot be used safely or when it fails.

PURPOSE: The Palliative Prognostic Index (PPI) was developed to improve survival prediction for advanced cancer patients. However, there is limited data about the PPI application in a real-world scenario. This study aimed to assess the accuracy of PPI > 6 in predicting survival of cancer inpatients. METHODS: A prospective observational cohort in an inpatient palliative care service at a tertiary hospital in São Paulo-SP, Brazil, between May 2011 and December 2018. RESULTS: We included 1,376 critically ill cancer inpatients. Patients were divided into three PPI subgroups: PPI ≤ 4, PPI 4-6, and PPI ≥ 6. Their respective medium overall survival values were 44 days (95% confidence interval [CI] 35.52-52.47), 20 days (95% CI 15.40-24.59), and 8 days (95% CI 7.02-8.98), (p < 0.001). PPI ≥ 6 predicted survival of <3 weeks with a positive predictive value (PPV) of 72% and an negative predictive value (NPV) of 68% (sensitivity 67%, specificity 72%). PPI > 4 predicted survival of <6 weeks with a PPV of 88% and an NPV of 36% (sensitivity 74%, specificity 59%). When PPI was <4, the mortality rate over 3 weeks was 39% with a relative risk (RR) of 0.15 (95% CI 0.11-0.20; p < 0.001), and the 6-week mortality rate was 63% with a RR of 0.18 (95% CI 0.13-0.25; p < 0.001) compared to PPI ≥ 4. CONCLUSIONS: PPI was a good discriminator of survival among critically ill cancer inpatients and could assist in hospital discharge decision. PPI may help healthcare policymakers and professionals in offering high-quality palliative care to patients.
RESUMO
BACKGROUND: The incidence of brain metastases (BM) in patients with renal cell carcinoma (RCC) is hypothesized to have increased in the last 2 decades. OBJECTIVE: To define incidence trends according to patient and clinical characteristics, to identify risk factors, and to describe outcomes of patients with BM for RCC. DESIGN, SETTING, AND PARTICIPANTS: Patients diagnosed with RCC between the years 2010 and 2013 within the Surveillance, Epidemiology, and End Results database. An external validation was also considered using patients diagnosed with RCC between 2010 and 2012 within the National Cancer Database. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Incidence proportions of BM were calculated. Risk factors correlated with BM at diagnosis were identified via a 1000-bootstrap corrected multivariable logistic regression model. A risk model was then developed and evaluated using measures of predictive accuracy. Overall survival was examined using Cox regression analyses. RESULTS AND LIMITATIONS: The overall incidence proportions of BM at RCC diagnosis was 1.51% (95% confidence interval: 1.39-1.64%). White/other race, clear cell histology, and sarcomatoid differentiation, T2-4 disease, tumor dimension >10â¯cm, and N+ disease were significantly associated with BM at RCC diagnosis, and retained within the final prediction model. A risk score was created based on these variables (c-index: 0.803). BM at RCC diagnosis occurred in 0.5%, 3.6%, and 7.7% of patients categorized as low risk, intermediate risk, and high risk. Patients with BM were more likely to succumb to any death than those without BM at diagnosis (median overall survival: 6.4 mo vs not reached, respectively, adjusted hazard ratio: 1.87, 95% confidence interval: 1.67-2.08, pâ¯<â¯0.001). The real incidence of BM at RCC diagnosis is likely underestimated given that the observed rate likely reflects patients who presented with symptoms. CONCLUSIONS: Patients with BM at RCC have poor oncological outcomes. We have characterized the epidemiology of BM at RCC diagnosis and developed a clinical risk model for the purpose of predicting the development of BMs in patients diagnosed with a cortical renal mass. PATIENT SUMMARY: In this report we examined recent proportions of patients with brain metastases at kidney cancer diagnosis in a large community database originating from the US. We developed a model that may be used during routine clinical practice to predict brain metastases. The urologic-oncological community may consider baseline imaging for brain metastases in patients without any symptoms but at high risk of having brain metastases according to the risk model. However, the proposed model certainly needs further testing and validation in the clinical setting. Future studies on brain metastases survival and treatment options are also needed.

INTRODUCTION: Observational studies have suggested that metformin use is associated with favorable outcomes in several cancers. For renal cell carcinoma (RCC), data have been limited. Therefore, we investigated the effect of metformin on survival in metastatic RCC (mRCC) using a large clinical trial database. PATIENTS AND METHODS: We conducted a retrospective analysis of patients with mRCC in phase II and III clinical trials. The overall survival (OS) in metformin users was compared with that of users of other antidiabetic agents and those not using antidiabetic agents. Progression-free survival, objective response rate, and adverse events were secondary endpoints. Subgroup analyses were conducted after stratifying by class of therapy, type of vascular endothelial growth factor tyrosine kinase inhibitors, and International Metastatic RCC Database Consortium (IMDC) risk groups. RESULTS: We identified 4736 patients with mRCC, including 486 with diabetes, of whom 218 (4.6%) were taking metformin. Metformin use did not affect OS when compared with users of other antidiabetic agents or those without diabetes. Furthermore, metformin use did not confer an OS advantage when stratified by class of therapy and IMDC risk group. However, in diabetic patients receiving sunitinib (n = 128), metformin use was associated with an improvement in OS compared with users of other antidiabetic agents (29.3 vs. 20.9 months, respectively; hazard ratio, 0.051; 95% confidence interval, 0.009-0.292; P = .0008). CONCLUSION: In the present study, we found a survival benefit for metformin use in mRCC patients treated with sunitinib. Clinical and preclinical studies are warranted to validate our results and guide the use of metformin in the clinic.

BACKGROUND: Spontaneous regression of metastatic melanoma and delayed responses more than one year after treatment with ipilimumab are rarely seen. CASE PRESENTATION: Here, we present the case of a patient with in transit metastases from cutaneous melanoma on his right lower extremity who achieved complete regression of all metastatic lesions 13 months after the first of two consecutive palliative resections of dominant masses and more than two years after treatment with ipilimumab. CONCLUSION: The exact cause of our patient's sudden onset of tumor regression remains speculative. We hypothesize that the operative trauma followed by the postoperative infections augmented an innate immune response.

BACKGROUND: Abiraterone and enzalutamide are currently approved for mCRPC patients. Both drugs have distinct mechanisms of action and may have different toxicity profile. There are limited data comparing the side effects of abiraterone and enzalutamide. We performed a meta-analysis of randomized controlled trials (RCT) to better characterize the risk of adverse events associated with both drugs. METHODS: We performed a literature search on MEDLINE for studies reporting abiraterone and enzalutamide side effects from January 1966 to July 31, 2015. Abstracts presented at ASCO meetings from 2004 to 2015 were selected manually. Phase III RCT were included in analysis. We assessed the risk of adverse events reported in RCT by performing two meta-analyses: abiraterone-prednisone vs. placebo-prednisone (2,283 pts) and enzalutamide vs. placebo (2,914 pts). Summary of incidence, relative-risks (RR), and 95% confidence intervals (CI) were calculated using random-effects or fixed-effects models based on the heterogeneity of included studies. RESULTS: Overall, enzalutamide was not associated with all-grade (RR 1.06 - 95% CI 0.67-1.65) or grade ≥3 (RR 0.81 - 95% CI 0.28-2.33) cardiovascular events, but was associated with increased risk of all-grade fatigue (RR 1.29 - 95% CI 1.15-1.44). On the other hand, abiraterone was associated with increased risk of all-grade (RR 1.28 - 95% CI 1.06-1.55) and grade ≥3 (RR 1.76 - 95% CI 1.12-2.75) cardiovascular events, but was not associated with all-grade (RR 0.85 - 95% CI 0.58-1.23) or grade ≥3 (RR 1.07 - 95% CI 0.97-1.19) fatigue. CONCLUSIONS: In this meta-analysis, abiraterone was associated with an increased risk of cardiovascular events, while enzalutamide was associated with an increased risk of fatigue.
RESUMO
Immune-related adverse events (irAE) have been described with immune checkpoint inhibitors (ICI), but the incidence and relative risk (RR) of irAEs associated with these drugs remains unclear. We selected five key irAEs from treatments with approved cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), programmed cell death 1 (PD-1), and programmed death ligand 1 (PD-L1) inhibitors (ipilimumab, nivolumab, or pembrolizumab, and atezolizumab, respectively) to better characterize their safety profile. We performed a meta-analysis of randomized phase II/III immunotherapy trials, with non-ICI control arms, conducted between 1996 and 2016. We calculated the incidence and RR of selected all-grade and high-grade gastrointestinal, liver, skin, endocrine, and pulmonary irAEs across the trials using random-effect models. Twenty-one trials were included, totaling 11,454 patients, of whom 6,528 received an ICI (nivolumab, 1,534; pembrolizumab, 1,522; atezolizumab, 751; and ipilimumab, 2,721) and 4,926 had not. Compared with non-ICI arms, ICIs were associated with more all-grade colitis (RR 7.66, P < 0.001), aspartate aminotransferase (AST) elevation (RR 1.80; P = 0.020), rash (RR 2.50; P = 0.001), hypothyroidism (RR 6.81; P < 0.001), and pneumonitis (RR 4.14; P = 0.012). Rates of high-grade colitis (RR 5.85; P < 0.001) and AST elevation (RR 2.79; P = 0.014) were higher in the ICI arms. Ipilimumab was associated with a higher risk of all-grade rash (P = 0.006) and high-grade colitis (P = 0.021) compared with PD-1/PD-L1 ICIs. Incidence of fatal irAE was < 1%. This meta-analysis offers substantial evidence that ICIs are associated with a small but significant increase in risk of selected all-grade irAEs and high-grade gastrointestinal and liver toxicities. Although fatal irAEs remain rare, AEs should be recognized promptly as early interventions may alleviate future complications. Cancer Immunol Res; 5(4); 312-8. ©2017 AACR.
RESUMO
PURPOSE: To evaluate the copaiba oil effect on urea and creatinine levels in rats submitted to kidney ischemia and reperfusion syndrome. METHODS: Eighteen Wistar rats (Rattus norvegicus albinus), aged between 90 and 120 days, weight between 200 g and 250 g, were allocated in 2 groups (n=9) and submitted to 50 minutes of renal ischemia and reperfusion and treated or not with copaiba oil (0.63 ml/kg daily seven days before ischemia). The nitrogen excrements were assessed at 24, 48 and 72 hours after ischemia period. RESULTS: The urea serum level was smaller (p d" 0,05) at 24 and 48 hours, and the creatinine serum level was smaller at 48 hours in animals treated with copaiba oil (GIRC) than the GIR. CONCLUSION: The copaiba oil decreased significantly the urea serum level at 24 and 48 hours and the creatinine level at 48 hours after kidney ischemia and reperfusion in rats.

BACKGROUND: A considerable number of patients with metastatic colorectal cancer progress after exhausting all approved standard therapies but maintain an adequate performance status and could be candidates for further treatment. We aim at reviewing our experience with sorafenib treatment of a patient with FLT3 mutation in refractory metastatic colorectal cancer. METHODS: Treatment with sorafenib of a patient with metastatic colorectal cancer and FLT3 translocation who had previously been heavily treated. RESULTS: The patient with metastatic colorectal cancer, aged 51 years, showed significant symptomatic and laboratory improvement with sorafenib treatment (400 mg twice daily). CONCLUSION: The presented case illustrates how an aggressive and refractory colorectal tumor may respond well to targeted therapy.
RESUMO
Cross-cultural adaptation and validation of the Impact Questionnaire of Urinary Incontinence (IIQ-7) and Urogenital Distress Inventory (UDI-6) - short scale - in the Brazilian population with multiple sclerosis. The IIQ-7 and UDI-6 were translated into Portuguese, called IIQ-7-BR and UDI-6-BR. The questionnaires were administered in 211 individuals selected randomly. Of these, 140 had MS according to McDonald criteria and 71 were included in the control group. In both questionnaires, the Cronbach's alpha coefficient was above 0.7. The IIQ-7-BR showed 94.31% concordance between the evaluated studies and UDI-6-BR, 93.33%. Thus, the instruments of this study were presented according to the standards proposed by the Instrument Review Criteria, reliability, validity and sensitivity, maintaining the original scales characteristics.

Descending necrotizing mediastinitis is a rare type of deep infection of the soft tissues of the face, originating from cervical and oral infections, typically dental infections. It is associated with high mortality, due to its high invasive potential and the fact that the diagnosis is often delayed. We report the case of a 42-year-old female patient presenting with severe trismus, fever, purulent intraoral drainage, dysphagia, and dysphonia, accompanied by edema and redness in the cervical region. She was diagnosed with necrotizing descending mediastinitis secondary to a dental infection after the extraction of a mandibular third molar. The patient underwent surgical drainage and intravenous antibiotic therapy. Despite the development of septicemia, the evolution was favorable and the patient was discharged on post-admission day 20. Early and accurate diagnosis, together with prompt treatment, is imperative for better outcomes in this rare condition.
