Capelini, Maria V.;Riccetto, Cassio L.;Dambros, Miriam;Tamanini, Jose T.;Herrmann, Viviane;Muller, Virginia;
International braz j urol , 2006, DOI: 10.1590/S1677-55382006000400015
Abstract: objective: prospective study to objectively evaluate the benefits of pelvic floor strengthening exercises associated to biofeedback for the treatment of stress urinary incontinence. materials and methods: fourteen patients diagnosed with stress urinary incontinence (sui) were selected for this study. all patients underwent a pelvic floor training associated to biofeedback for 12 consecutive weeks. urodynamic tests, pad test and bladder diary were analyzed at the beginning of the study, at the end and after 3 months. the king's health questionnaire (khq) was applied before and after treatment to assess the impact in the quality of life. results: there was a significant reduction in the pad weight (from 14.21 g to 1 g), number of urinary leakage episodes (from 8.14 per day to 2.57 per day) and daytime frequency (from 7.93 per day to 5.85 per day). at urodynamics the authors observed a significant increase in valsalva leak-point pressure (from 103.93 cm h2o to 139.14 cm h2o), cistometric capacity (from 249.29 ml to 336.43 ml, p = 0.0015) and bladder volume at first desire to void (from 145 ml to 215.71 ml). those differences were kept during the first 3 months of follow up. the khq revealed significant differences except in the case of "general health perception", which covers health in general and not exclusively urinary incontinence. conclusion: treatment of sui with pelvic floor exercises associated to biofeedback caused significant changes in the parameters analyzed, with maintenance of good results 3 months after treatment.

Abstract: INTRODUCTION: SAFYRE is a readjustable and minimally invasive sling for the treatment of stress urinary incontinence (SUI). It is as a pubovaginal sling placed in the medial third of the urethra. The initial experience is described. MATERIALS AND METHODS: Forty-five patients (mean age = 59 years) underwent a SAFYRE implant to treat SUI. Physical examination and urodynamic study were performed before surgery. All patients presented symptoms of SUI and 20% also reported mild urgency. Approximately 60% of this group had a previously failed anti-incontinence procedure. Urethral hypermobility was diagnosed in 40% of the patients and intrinsic sphincter deficiency (ISD) in 60% of the cases. RESULTS: The average follow up period was 10 months. The mean operative time was 20 minutes. Dystopia repair was performed whenever necessary, during the same procedure. The average hospital stay was 24 hours. In 11% of the implants, bladder perforation occurred. During the postoperative period, 9 patients (20%) developed transient urgency symptoms. During the initial follow up period, 90% were found to be continent, 3% reported an improvement and 7% were unchanged. CONCLUSION: SAFYRE is a safe and quick procedure that allows postoperative readjustment. This technique may be an attractive alternative in the management of SUI, should the good result obtained so far prove to be long lasting.

Physics , 2013, DOI: 10.1088/2041-8205/777/2/L34
Abstract: Planetary transits are commonly observed at visible wavelengths. Here we investigate the shape of a planetary transit observed at radio wavelengths. Solar maps of the Sun at 17 GHz are used as a proxy for the stellar eclipse by several sizes of planets from Super-Earths to Hot Jupiters. The relative depth at mid transit is the same as observed at visible wavelengths, but the limb brightening of the stellar disk at 17 GHz is clearly seen in the shape of the transit light curve. Moreover, when the planet occults an active region the depth of the transit decreases even further, depending on the brightness of the active region relative to the surrounding disk. For intense active region, with 50 times the brightness temperature of the surrounding disk, the decrease can supersede the unperturbed transit depth depending on the size of the eclipsing planet. For a Super-Earth (R_p=0.02 R_s) crossing, the decrease in intensity is 0.04%, increasing to 0.86% in the case when a strong active region is present. On the other hand, for a hot Jupiter with R_p=0.17 R_s, the unperturbed transit depth is 3% increasing to 4.7% when covering this strong active region. This kind of behavior can be verified with observation of planetary transits with the ALMA radio interferometer.

Abstract: background: this study evaluated the efficacy of 24-week, group-based, behavioral therapy in improving quality of life (qol) among men treated for localized prostate carcinoma (pc) by means of radical prostatectomy (rp) who presented treatment-related dysfunctions: urinary incontinence (ui) and erectile dysfunction (ed). patients and methods: thirty men were assigned to 24-week behavioral group therapy. the intervention was designed to improve qol by helping participants to identify and effectively manage stressful experiences. it focused on treatment-related sequelae from pc. differences in variables were compared between the beginning and end of the study by means of student?s t test for paired samples. multiple analysis was carried out by stepwise multiple linear regression following bivariate pearson?s correlation analysis. this was achieved for all predictors (i.e. general health perception, ed and ui impact) and relevant covariates (i.e. age, work/retirement status, alcohol addiction, attitude towards cancer and surgery, sexual satisfaction, and future plans). results: in all patients the time elapsed from surgery to attending the behavioral group therapy exceeded 24 months. there was no significant correlation between this time and the predictor variables. general health perception scores decreased by the end of the study (p=0.000), as did the ui impact score (p=0.023), thus denoting improvement in both factors. the difference in ui impact scores correlated negatively and significantly with both age (p=0.04) and work/retirement (p=0.05). multiple stepwise regression showed that age was the most important variable (r2=26.0%). considering age and work/retirement simultaneously, there was an increase of 10.3% (r2=36.3%). ed increased by the end of the study (p=0.000), and the difference between the ed scores correlated positively and significantly with sexual satisfaction alone (p=0.029), which signifies that previous sexual satisfaction had a positive influence
A Survey of Extended H$_2$ Emission from Massive YSOs

Physics , 2015, DOI: 10.1093/mnras/stv914
Abstract: We present the results from a survey, designed to investigate the accretion process of massive young stellar objects (MYSOs) through near infrared narrow band imaging using the H$_2$ $\nu$=1-0 S(1) transition filter. A sample of 353 Massive Young Stellar Object (MYSO) candidates was selected from the Red MSX Source survey using photometric criteria at longer wavelengths (infrared and submillimeter) and chosen with positions throughout the Galactic Plane. Our survey was carried out at the SOAR Telescope in Chile and CFHT in Hawaii covering both hemispheres. The data reveal that extended H$_2$ emission is a good tracer of outflow activity, which is a signpost of accretion process on young massive stars. Almost half of the sample exhibit extended H$_2$ emission and 74 sources (21\%) have polar morphology, suggesting collimated outflows. The polar-like structures are more likely to appear on radio-quiet sources, indicating these structures occur during the pre-UCHII phase. We also found an important fraction of sources associated with fluorescent H$_2$ diffuse emission that could be due to a more evolved phase. The images also indicate only $\sim$23\% (80) of the sample is associated with extant (young) stellar clusters. These results support the scenario in which massive stars are formed by accretion disks, since the merging of low mass stars would not produce outflow structures.

Abstract: introduction: the present study aims to evaluate the association between nocturia and falls in a group of community-living elderly men in the city of s?o paulo (brazil). material and methods: under the coordination of the pan american health organization and world health organization, a multicenter study named health, welfare and aging (sabe study) is being conducted to evaluate the living and health conditions of older people in latin america and caribbean. in brazil, this study is evaluating the elderly population (60 years or more) in s?o paulo since 2000. the presence of nocturia was taken as the response "yes" to the question "do you need to void three times or more at night?". the presence of falls was also taken as the response "yes" to the question "did you have any fall during the last 12 months?" the intergroup analysis used was the logistic regression. results: total of 865 men was interviewed, mean age 68 years. it was observed high prevalence of nocturia and falls in all groups, with higher prevalence of both in the eldest group (p<0.001), however, the association of nocturia and falls was not statistically significant in any of the groups (p=0.45). conclusion: this is one of the pioneering studies that assess only the male population, showing that nocturia was not significantly associated with falls. nocturia and falls are highly prevalent conditions in the elderly, but no association was found between both, so that these variables may be correlated to age and other clinical conditions.

International braz j urol , 2004,
Abstract: PURPOSE: We have evaluated the clinical and urodynamic effects of intravesical instillation of resiniferatoxin in patients with idiopathic detrusor instability refractory to anticholinergics. MATERIALS AND METHODS: There were 30 women, median age 56 years old with detrusor instability for over 6 months and a history of anticholinergic use with no response or intolerable collateral effects. A 50 nM solution of resiniferatoxin was prepared for intravesical instillation. All patients were evaluated for urinary symptoms, as well as for urodynamic assessments before and 30 days after instillation. Tolerability was analyzed during the instillation. RESULTS: A clinical improvement was observed in 30% of the patients with urinary urgency and in 33% of the patients with urge-incontinence. The mean maximum cystometric capacity before application was 303.9 ± 78.9 and after application 341 ± 84.6. No significant difference was observed (p = 0.585). The mean maximum amplitude of the contractions diminished from 47.86 ± 29.64 to 38.72 ± 30.77 (p = 0.002). CONCLUSIONS: Resiniferatoxin, in this concentration, proved to be useful in a small percentage of patients regarding clinical detrusor instability. Maximum amplitude of the involuntary contractions was significantly reduced and in 33% patients the involuntary contractions disappeared. Further studies with different concentrations are recommended.

Grinberg, Cassio
Sess?es do Imaginário , 2007,
Abstract: O artigo discute aspectos da comunica o presentes na chamada ‘Trilogia da América’ do escritor americano Philip Roth. Composta pelos romances Pastoral Americana (1997), Casei com um comunista (1998) e A marca humana (2000), a trilogia possibilita por meio da estrutura da trama e do comportamento dos personagens um paralelo com fen menos da comunica o social relacionados à proximidade, ao espetáculo e à moral. Ao final, uma perspectiva histórica ajuda a explicar o porquê da escolha desses temas por parte do autor. The paper explores communicational aspects related with the American writer Philip Roth’s ‘American Trilogy’. Presented by the novels American pastoral (1997), I married a communist (1998) and The human stain (2000), the trilogy makes possible through the structure of the plot and the behavior of the characters a parallel with social communicational phenomena related to proximity, spectacle and moral. At the end, a historical perspective helps to explain the reasons why the author chooses such themes.
