    Purpose: To analyze the influence of urethral mobility and Valsalva leak point pressure on postoperative outcomes of transobturator sling (TOT) for female stress urinary incontinence. Materials and Methods: A prospective cohort was conducted including 66 patients submitted to TOT from March 2006 to May 2009. Urethral hypermobility was defined as mobility ≥ 30º on Q-tip test, and Valsalva leak point pressure (VLPP) was classified as greater than 60 cmH 2 O or 60 and less on preoperative urodynamics. These parameters were compared through well defined postoperative objective and subjective success criteria. Intensity of urinary leakage and quality of life was analysed by ICIQ-SF. Statistical analysis was accomplished and the results rendered significant if p < 0.05. Results: Mean follow up was 10 months (3 to 28). Mean age was 55 years (33 to 80), 70% were white and 30% African descendent, mean body mass index was 27 (21 to 38), average vaginal and abdominal deliveries were 2.8 and 0.5 respectively. A quarter had prior stress incontinence surgery. Patients with urethral hypermobility had higher objective success rates (98% versus 81.25%, p = 0.04). The subjective success rate was also greater in the hypermobility group (84% versus 62.5%), but statistical significance was not reached (p = 0.07). VLPP had no influence on either objective or subjective postoperative success rates (p = 0.17 and 0.34, respectively). In the subgroup analysis, those with low mobility and high VLPP had worse objective success rates in comparison to the group with hypermobility and low VLPP (p = 0.04) and also in relation to the remaining of the studied population. Other possible prognostic factors (previous surgery, mixed incontinence, gestational status) had no influence on success rates. Conclusions: High urethral mobility, regardless of the sphincteric status indicated by VLPP, is a favorable prognostic factor for tension-free transobturator tape procedure. No relationship was demonstrated between postoperative success rates and VLPP

To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050.

    Abstract INTRODUCTION: This study aimed to identify the prevalence of urodynamic changes with an associated risk of developing upper urinary tract damage in neuroschistosomiasis patients. METHODS: A prospective study was conducted, wherein68 patients were admitted for analysis of urodynamics, urea and creatinine levels, and uroculture. RESULTS: Blood test results did not indicate kidney failure. There were cases of asymptomatic bacteriuria. Common symptoms were frequent nocturia and detrusor overactivity. Results of low compliance and low cystometric capacity were both statistically significant (p = 0.001 and p = 0.002, respectively). CONCLUSIONS: A high prevalence of negative urodynamic changes were found in neuroschistosomiasis patients

    ABSTRACT Surgical correction is the most efficient treatment for stress urinary incontinence (SUI), and transobturator sling (TO) has optimal results. The high cost of commercially available sling kits makes it difficult the access in most Brazilian public health services. Hand-made polypropylene slings, on the other hand, have been previously reported. The aim of the present study was to compare the effectiveness and safety of commercial vs. hand-made polypropylene mesh slings. Data from 57 women who underwent consecutive TO sling surgery to treat SUI were pros- pectively collected between 2012 and 2014, and divided in two groups for further compa- rison. In Group-1, 31 women underwent surgery with commercial slings. In Group-2, 26 women underwent hand-made polypropylene slings. Women were compared according to epidemiological data, perioperative evaluation, quality of life, urodynamic study, cure and complication rates. Results were objectively (stress test with Valsalva maneuver, with at least 200mL vesical repletion) and subjectively evaluated by the Patient Global Impression of Improvement(PGI-I), Visual Analog Scale (VAS) and ICIQ-SF. Success was defined as PGI-I, VAS and negative stress test. Group-1 (n=31) and Group-2 (n=26) had a mean age of 60 vs. 58years (p=0.386). All de- mographic data were similar. The mean VLPP was 75.6cmH2O vs. 76.6cmH2O (p=0.88). The mean follow-up was 24.3 vs. 21.5months (p=0.96). Success rates were 74.2% vs. 80.2% (p=0.556), with ICIQ-SF variation of 12.6 vs.15.5 (p=0.139) and PGI-I of 71% vs. 80% (p=0.225). There was only one major complication (urethrovaginal fistula in Group-1). In conclusion, handmade and commercial slings have similar effectiveness and safety. The manufacture technique has important key-points stated in the present manuscript

    ATLANTIC BIRD TRAITS: a data set of bird morphological traits from the Atlantic forests of South America

    Scientists have long been trying to understand why the Neotropical region holds the highest diversity of birds on Earth. Recently, there has been increased interest in morphological variation between and within species, and in how climate, topography, and anthropogenic pressures may explain and affect phenotypic variation. Because morphological data are not always available for many species at the local or regional scale, we are limited in our understanding of intra- and interspecies spatial morphological variation. Here, we present the ATLANTIC BIRD TRAITS, a data set that includes measurements of up to 44 morphological traits in 67,197 bird records from 2,790 populations distributed throughout the Atlantic forests of South America. This data set comprises information, compiled over two centuries (1820–2018), for 711 bird species, which represent 80% of all known bird diversity in the Atlantic Forest. Among the most commonly reported traits are sex (n = 65,717), age (n = 63,852), body mass (n = 58,768), flight molt presence (n = 44,941), molt presence (n = 44,847), body molt presence (n = 44,606), tail length (n = 43,005), reproductive stage (n = 42,588), bill length (n = 37,409), body length (n = 28,394), right wing length (n = 21,950), tarsus length (n = 20,342), and wing length (n = 18,071). The most frequently recorded species are Chiroxiphia caudata (n = 1,837), Turdus albicollis (n = 1,658), Trichothraupis melanops (n = 1,468), Turdus leucomelas (n = 1,436), and Basileuterus culicivorus (n = 1,384). The species recorded in the greatest number of sampling localities are Basileuterus culicivorus (n = 243), Trichothraupis melanops (n = 242), Chiroxiphia caudata (n = 210), Platyrinchus mystaceus (n = 208), and Turdus rufiventris (n = 191). ATLANTIC BIRD TRAITS (ABT) is the most comprehensive data set on measurements of bird morphological traits found in a biodiversity hotspot; it provides data for basic and applied research at multiple scales, from individual to community, and from the local to the macroecological perspectives.
