title: Is moderate hypofractionation accepted as a new standard of care in north america for prostate cancer patients treated with external beam radiotherapy? Survey of genitourinary expert radiation oncologists

description: ABSTRACT  Introduction: Several recent randomized clinical trials have evaluated hypofractionated regimens against conventionally fractionated EBRT and shown similar effectiveness with conflicting toxicity results. The current view regarding hypofractionation compared to conventional EBRT among North American genitourinary experts for management of prostate cancer has not been investigated.  Materials and Methods: A survey was distributed to 88 practicing North American GU physicians serving on decision - making committees of cooperative group research organizations. Questions pertained to opinions regarding the default EBRT dose and fractionation for a hypothetical example of a favorable intermediate - risk prostate cancer (Gleason 3 + 4). Treatment recommendations were correlated with practice patterns using Fisher's exact test.  Results: Forty - two respondents (48%) completed the survey. We excluded from analysis two respondents who selected radical hypofractionation with 5 – 12 fractions as a preferred treatment modality. Among the 40 analyzed respondents, 23 (57.5%) recommend conventional fractionation and 17 (42.5%) recommended moderate hypofractionation. No demographic factors were found to be associated with preference for a fractionation regimen. Support for brachytherapy as a first choice treatment modality for low - risk prostate cancer was borderline significantly associated with support for moderate hypofractionated EBRT treatment modality (p = 0.089).  Conclusions: There is an almost equal split among North American GU expert radiation oncologists regarding the appropriateness to consider moderately hypofractionated EBRT as a new standard of care in management of patients with prostate cancer. Physicians who embrace brachytherapy may be more inclined to support moderate hypofractionated regimen for EBRT. It is unclear whether reports with longer follow-ups will impact this balance, or whether national care and reimbursement policies will drive the clinical decisions. In the day and age of patient - centered care delivery, patients should receive an objective recommendation based on available clinical evidence. The stark division among GU experts may influence the design of future clinical trials utilizing EBRT for patients with prostate cancer.

title: Clinical Features and Management of Women with Borderline Ovarian Tumors in a Single Center in Brazil

description: Abstract  Objective  The aim of the present study was to describe and analyze data of 57 women with borderline ovarian tumors (BOTs) regarding histological characteristics, clinical features and treatment management at the Department of Obstetrics and Gynecology of the Universidade Estadual de Campinas (Unicamp, in the Portuguese acronym).  Methods  The present retrospective study analyzed data obtained from clinical and histopathological reports of women with BOTs treated in a single cancer center between 2010 and 2018.  Results  A total of 57 women were included, with a mean age of 48.42 years old (15.43- 80.77), of which 30 (52.63%) were postmenopausal, and 18 (31.58%) were &lt; 40 years old. All of the women underwent surgery. A total of 37 women (64.91%) were submitted to complete surgical staging for BOT, and none (0/57) were submitted to pelvic or paraortic lymphadenectomy. Chemotherapy was administered for two patients who recurred. The final histological diagnoses were: serous in 20 (35.09%) cases, mucinous in 26 (45.61%), seromucinous in 10 (17.54%), and endometrioid in 1 (1.75%) case. Intraoperative analyses of frozen sections were obtained in 42 (73.68%) women, of which 28 (66.67%) matched with the final diagnosis. The mean follow-up was of 42.79 months (range: 2.03-104.87 months). Regard ingthe current status of the women, 45(78.95%) are alive without disease, 2(3.51%) arealive with disease, 9 (15.79%) had their last follow-up visit &gt; 1 year beforethe performanceof the present study but arealive, and 1 patient(1.75%) died of another cause.  Conclusion  Women in the present study were treated according to the current guidelines and only two patients recurred.

title: Variables Associated with Endometriosis-related Pain: A Pilot Study using a Visual Analogue Scale

description: Abstract  Objective  Endometriosis is a complex disease, and pain is an important component of the syndrome. One of the most used methods to assess pain is the visual analogue scale (VAS). The aim of the present research was to study the pain experienced by patients who referred to our unit for endometriosis, using the VAS to understand the variables that could influence it.  Methods  We have conducted a prospective study from February 2012 to December 2016, enrolling 388 patients who referred to a university hospital, in Florence, Italy. We have included in the present study patients during their follow-up for endometriosis; we have also included patients who underwent surgery with a histological diagnosis of endometriosis. We have collected sociodemographic and clinical information regarding age, body mass index (BMI), smoking habit, number of pregnancies, and endometriosis staging. Finally, we have administered the VAS for several symptoms.  Results  Dysmenorrhea was the symptom associated with the highest perception of pain (mean VAS score of 5.76). The logistic regression showed that the stage of endometriosis could influence the pain associated to constipation and to dysuria. The linear regression showed that age couldinfluencethe pain associated to constipation, to dyspareunia,and to dysmenorrhea. A positive correlation was found between dysmenorrhea and chronic pelvic pain(CPP), between dysmenorrhea and dyspareunia, and between constipation and dysuria.  Conclusion  Using a validated method, the VAS, we have studied the pain experienced by a group of patients with a history of endometriosis and observed that smoking habit and BMI did not influence the VAS scores, and that dysmenorrhea was associated with the highest perception of pain.

title: The impact of long-term consumption of diets enriched with olive, cottonseed or sesame oils on kidney morphology: A stereological study

description: Abstract: To date, most of studies have only focused on metabolic effects of dietary oils while recent evidence proposes that they can influence kidneys structure. Therefore, the aim of this study was to evaluate the impact of long-term consumption of olive, cottonseed and sesame oils on renal morphology in rats. 70 male Wistar rats randomly assigned into seven equal groups and treated with standard diet (control), the standard diet enriched with 10% or 20% (W/W) of either olive oil (OLI10%, OLI20%), cottonseed oil (COT10%, COT20%) or sesame oil (SES10%, SES20%) for 5 months. Quantitative features of the kidney including kidney and cortex volumes and the number of glomeruli were analyzed stereologically. Moreover, kidney sections histologically were evaluated. All of the studied oils in low concentration had no devastating effects on renal morphology and also its pathological features. However, only in SES20% group, kidney volume as well as, cortical volume was higher than the control group. Besides, accumulation of carbohydrate macromolecules and renal fibrosis were markedly increased in SES20% group compared to the control. The results suggest that sesame oil, especially at high concentration, may lead to renal deformities as a result of histopathological changes such as dilatation, fibrosis, and tubular defects.

title: Ingestion of a drink containing carbohydrate increases the number of bench press repetitions

description: ABSTRACT  Objective The aim of this study was to analyze the effects of carbohydrate ingestion prior to exercise on the number of bench press repetitions.  Methods Eight male physically active (21.3±2.7 years, 176±5cm, 73.12±6.12kg), with a minimum experience of at least one year exercising regularly, visited the laboratory at three moments. During the first visit, candidates went through their anthropometric evaluation and the application of their maximum number of bench press repetitions. The experimental tests were performed during their second and third visits in a crossover and blind study. The participants performed the maximum number of repetitions with an intensity of 70% of their maximum repetition strength. One hour before the experimental trials, participants randomly ingested a solution containing either carbohydrate or a placebo.  Results The ingestion of carbohydrate increases muscle resistance in relation to placebo (p=0.014; effect size=0.71). This is evidenced by the increase in the number of repetitions (12.9±2.4 and 11.3±1.9, respectively). The individual’s perception of effort is higher in the carbohydrate group than in the placebo group after exhaustion (4±0.93 and 3.1±0.64, respectively, p=0.006, effect size=0.89).  Conclusion It is concluded that a previous intake of carbohydrate is useful in improving performance in resistance exercises, providing an increase in the individual’s perception of effort.

title: A Procedure for Assessment of the Reducing Capacity of Plants-Derived Beverages Based on the Formation of the FeII/2,2’-Bipyridine Complex

description: An alternative spectrophotometric ferric reducing activity power (FRAP) method for quantification of total reducing capacity (TRC) was developed. The method is based on the reduction of FeIII to FeII by antioxidant compounds containing 2,2’-bipyridine (bipy) in aqueous solution. Absorbance values recorded at 521 nm, characteristic of the Fe(bipy)32+ complex formed, were used to determine the TRC of some plants-derived beverages. For the teas samples, the TRC values obtained with the proposed method and cupric reducing antioxidant capacity (CUPRAC) reagent had an excellent agreement (adjusted correlation coefficient (r2) = 0.951). Concerning herbs samples, the TRC values obtained with the proposed FRAP method correlated very well with values obtained using the 2,2’-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS•+) method (adjusted r2 = 0.975). It can be inferred from these results that other beverages derived from plants (e.g., beers, wines, and fruits juices) could also be analyzed with this new FRAP assay. In addition, the reducing capacity of 21 phenolic derivatives was determined with the proposed method in order to elucidate their structure-reactivity relationship. As expected, the phenolic derivative structure changes greatly the TRC values obtained with this proposed FRAP assay.

title: Relationship between periodontal outcomes and serum biomarkers changes after non-surgical periodontal therapy

description: Abstract: The systemic effect of chronic periodontitis (CP) has been suggested by several studies as an etiologic factor and modulator of diseases based on the changes in the inflammatory marker levels. This study aimed to investigate the relationship between the changes in clinical periodontal outcomes and serum biomarkers (CRP, IL-6, albumin and percentage of leukocytes) after non-surgical periodontal therapy in systemically healthy adults. An interventional study was conducted with a sample of 29 individuals without CP (control group) and 33 with CP (CP group). Periodontal clinical variables were recorded, and the serum levels of inflammatory markers were measured. Statistical analysis included the chi-square and Student’s t-tests and Pearson’s correlation analysis. After 90 days of non-surgical periodontal treatment, a reduction of periodontal parameters and IL-6 in both groups could be observed (P &lt; 0.001). The correlation analysis revealed a directly proportional correlation between changes in the probing depth (r = 0.349, P = 0.049) and clinical attachment level (r = 0.374, P = 0.034) with CRP in the CP group. The findings suggest a reduction of IL-6 serum concentration and periodontal clinical measures 90 days after periodontal therapy in both groups.

title: Mapping Study on the Use of Digital Games for Persons with Disabilities in Upper Members

description: Abstract: Digital games are no longer seen as a form of entertainment detrimental to health. They have become an important tool to improve the treatment of patients, ranging from those who are experiencing a serious illness, such as cancer, to those requiring milder procedures such as physiotherapy. However, there are people who are physically disabled and have difficulty playing digital games. In this line of reasoning, this work presents a systematic review on the use of digital games for people with physical disabilities in the upper limbs. The sources of research were the following indexed databases: IEEE Xplore, Portal of Periodicals of the Coordination of Improvement of Personnel of Higher Level (CAPES), PubMed, Scielo, Science Direct, Scopus and Web of Science. It should be noted that the application of Systematic Mapping in the elaboration of a bibliographical review allowed to identify the main gaps for the development of new research, and to redirect to the main publications related to the study. Finally, the results shows that it is an area that is constantly expanding.

title: Assessment of Anti-inflammatory and Antioxidant Properties of Safranal on CCI4-Induced Oxidative Stress and Inflammation in Rats

description: Abstract: The present study aimed to determine the antioxidative and anti-inflammatory effects of safranal on damage induced by CCl4. Experimental animals were divided into five groups. The first group was determined as the control group and no treatment was conducted. Second group rats were administered 1 mL/kg-day CCI4 during the experiment. Rats in Groups 3, 4 and 5 were administered 1 mL/kg-day CCI4 and 25 mg/kg, 50 mg/kg; 100 mg/kg safranal, respectively via gavage. Oxidative-antioxidant parameters, liver function enzymes and inflammatory cytokine levels were determined in liver samples obtained from the rats. Data analysis demonstrated that oxidative stress and inflammation markers were significantly higher in CCI4 administered groups (p&lt;0.05). Antioxidant parameters in high-dose safranal administered groups were not different when compared to the control group. Safranal had ameliorating effects on the increased liver function enzymes activities in CCI4 administered groups. In conclusion, it was observed that CCI4 administration led to hepatic damage and increased oxidative stress and inflammatory cytokine levels. It was observed that particularly high-dose administration of safranal promoted the antioxidant system. Safranal administration was not effective on IL-1β levels. However, high-dose (100 mg/kg) safranal was found to be inflammatory against TNF-α and IL-6 cytokines. In conclusion, it can be said that safranal has an anti-inflammatory potential and has a strong antioxidative effect.

title: Prostate brachytherapy with iodine-125 seeds: analysis of a single institutional cohort

description: ABSTRACT  Objectives: Brachytherapy (BT) with iodine-125 seeds placement is a consolidated treatment for prostate cancer. The objective of this study was to assess the clinical outcomes in patients with prostate cancer who underwent low-dose-rate (LDR) -BT alone in a single Brazilian institution.  Materials and Methods: Patients treated with iodine-125 BT were retrospectively assessed after at least 5 years of follow-up. Patients who received combination therapy (External beam radiation therapy-EBRT and BT) and salvage BT were not included.  Results: 406 men were included in the study (65.5% low-risk, 30% intermediate-risk, and 4.5% high-risk patients). After a median follow-up of 87.5 months, 61 (15.0%) patients developed biochemical recurrence. The actuarial biochemical failure-free survival (BFFS) at 5 and 10 years were 90.6% and 82.2%, respectively. A PSA nadir ≥ 1 ng / mL was associated with a higher risk of biochemical failure (HR = 5.81; 95% CI: 3.39 to 9.94; p ≤ 0.001). The actuarial metastasis-free survival (MFS) at 5 and 10 years were 98.3% and 94%, respectively. The actuarial overall survival (OS) at 5 and 10 years were 96.2% and 85.1%, respectively. Acute and late grade 2 and 3 gastrointestinal toxicities were observed in 5.6%, 0.5%, 4.6% and 0.5% of cases, respectively. For genitourinary the observed acute and late grade 2 and 3 toxicities rates were 57.3%, 3.6%, 28% and 3.1%, respectively. No grade 4 and 5 were observed.  Conclusions: BT was effective as a definitive treatment modality for prostate cancer, and its endpoints and toxicities were comparable to those of the main series in the literature.

title: African star grass response to postemergence herbicides

description: ABSTRACT Cynodon nlemfuensis Vanderyst, commonly called African star grass, is excellent forage in pasture formation and herd feeding. However, little information is available regarding weed management in areas of star grasses. Two field experiments were carried out in 2017 and 2018 to evaluate the response of African star grass to postemergence herbicides. The treatments applied were as follows: 2,4-D (1,340.0 g ae ha-1); 2,4-D + picloram (720.0 +192.0 g ae ha-1 + 0.3% v/v nonionic surfactant); fluroxypyr + picloram (80.0 + 80.0 g ae ha-1 + 0.3% v/v mineral oil); fluroxypyr + aminopyralid (160.0 + 80.0 g ae ha-1 + 0.3% v/v mineral oil); fluroxypyr + triclopyr (320.0 + 960.0 g ae ha-1 + 0.3% v/v mineral oil); bentazon (720.0 g ai ha-1 + 0.5% v/v mineral oil); imazapyr (25.0 g ai ha-1); monosodium methyl arsenate (MSMA) (1,440.0 g ai ha-1 + 0.1% v/v nonionic surfactant); atrazine + S-metolachlor (1,480.0 + 1,160.0 g ai ha-1); atrazine + tembotrione (1,000.0 + 100.8 g ai ha-1 + 0.3% v/v mineral oil) and a control without herbicide application. The most phytotoxic treatments for the African star grass plants were fluroxypyr + amininopyralid, fluroxypyr + triclopyr and atrazine + tembotrione. The dry matter yield of star grass plants was not reduced by the applications of 2,4-D, 2,4-D + picloram, bentazon, imazapyr, MSMA and atrazine + S-metolachlor. These herbicides can be considered potential practices in African star grass crop management.
