Introduction: The diagnosis of small renal masses and the endophytic tumor approach have become challenging. This study aims to describe exclusively robot-assisted surgery as an alternative nephron-sparing approach for renal intraparenchymal tumors. Patients and Methods: We retrospectively analyzed all patients with completely endophytic tumors undergoing robot-assisted partial nephrectomy, treated under the Da Vinci System®, aided by intraoperative ultrasound. The patients’ demographic characteristics, perioperative and oncological outcomes were assessed. Results: From a total of 13 partial nephrectomies performed between 06/2010 and 10/2021, all patients underwent nephrotomy. The patients’ mean age was 52 years and the tumor measured mean 2.6 cm. Warm ischemia time was 24 minutes and histopathological analysis revealed that 12 patients had renal cell carcinoma. In a mean 36-month follow-up, no significant renal function alterations were found and no local or systemic recurrences occurred. Conclusion: Robot-assisted access is a safe and effective option for the nephron-sparing technique in completely intraparenchymal renal tumors.

Parrots are among the most popular pets in the world and they are also some of the most illegally traded, particularly in Brazil. Some computational tools were recently developed by researchers based on molecular databases for taxonomy support, forensic identification and conservation purposes. In this study, the DNA Surveillance platform was used to build an online database tool for molecular identification of Brazilian Psittacids using DNA sequences of six mitochondrial genes. To illustrate possible taxonomic issues of the online tool due to interspecific hybridization or unresolved taxonomy, we focused on Amazona aestiva that is considered as one of the most common parrots in Brazil, commonly bred as pets, and considered to be part of a species complex with Amazona ochrocephala from South America. We provide three curated sequence databases, which allow the species identification of individuals or tissue samples of birds of the Psittacidae family using mitochondrial DNA markers, and a comprehensive description of a taxonomic issue involving the A. ochrocephala complex. The results obtained corroborate previous studies suggesting that these species are not reciprocally monophyletic, due to either an ancient hybridization in central Brazil, or, they maybe just are morpho-varieties of the same species. Alternatively, if A. aestiva and A. ochrocephala were considered as sister species, the data could be interpreted either as a result of secondary contact or incipient speciation. Beyond the use of mtDNA for species identification, the high mtDNA haplotype diversity observed in A. aestiva indicates its potential use in discrimination of lineages that could be an important auxiliary tool to certify the captive origin of legally commercialized parrots.

The understanding of unsaturated flow in heterogeneous formations is a prerequisite to the understanding of pollutant transfer in the vadose zone and the proper management of infiltration basins settled over such heterogeneous formations. This study addresses the effect of lithological heterogeneity of a glaciofluvial deposit on flow in the vadose zone underneath an infiltration basin settled in the Lyon suburbs. The basin had already been the subject of several previous studies, some of which demonstrated the impact of soil heterogeneity. But all of them were only based on the sedimentological study of a trench and no study addressed the potential spatial variability of results due to the spatial variability of soil heterogeneity. In this study, we model flow in the vadose zone for several case studies, including drainage, water infiltration during a rainfall event, and a complete meteorological chronic. These calculations were conducted for several sections, previously characterized in the basin using GPR and sedimentological study and compared with a blank (homogeneous section). The results clearly show that heterogeneity impacts unsaturated flow and that these impacts depend upon the section considered. Some geometrical architectural and textural parameters were proposed to explain the spatial variability and effect of the soil heterogeneity on unsaturated flow, thus establishing the first step towards modeling unsaturated flow in the basin at the meso-scale.

The provision of care by health professionals seems to be related to cultural patterns in which these workers are inserted. The relationship between culture and care becomes a challenge for the provision of health care to homosexual and bisexual population. Thus, this study aimed to identify the perception of Gays, Lesbians, Bisexuals and Transgenders in relation to the care received from health professionals, in the light of Cross-Cultural Theory. This is a qualitative, ethnographic study, conducted with 30 members of sexual minorities in Juazeiro do Norte, Brazil. The data analysis lead to the elaboration of five categories based on of the Theory of Cultural Care Diversity and Universality. The participants emphasized the constant violation of their rights to universal and equitable access to the National Health System, stating that they have suffered from prejudice and exclusion, as result of a heteronormative culture. They highlighted that homophobia and dehumanization of care have a strong relation to sexual orientation. The transvestites are the most prone to humiliation and pejorative attitudes of professionals and such condition is a barrier to accessing services.

Purpose: The aim of this study was to isolate and identify potentially pathogenic airborne fungi from Hospital das Clínicas Samuel Libanio in the city of Pouso Alegre-MG and evaluate their susceptibility to natural and industrial products. Methods: The air collection was performed by passive sedimentation in the morning during the autumn and winter seasons. Petri dishes were open as the location of air conditioning. The isolates were subjected to pathogenicity test. The identification of the fungi was performed according to the macroscopic evaluation and micromorphology. Potentially pathogenic isolates were susceptibility tested by disc diffusion method. The agents used were insecticides and industrial cleaning products and essential oils of citronella plants, lemon grass, eucalyptus and Melaleuca extracted by steam distillation method. Results: We obtained a total of 356 fungal isolates. The inside door environments were 126 (35.39%) and the outside environments were 230 (64.6%) isolates. The 22 (6.18%) isolates from the inside and 25 (6.18%) outside the hospital showed pathogenic potential. This isolates were identified as Acremonium spp., A. niger, A. terreus, A. versicolor, Curvularia sp., Penicillium sp. and Scopulariopsis sp. Susceptibility testing it was observed that most of the isolates were susceptible to the principle product containing sodium hypochlorite. Citronella oil showed enormous potential inhibition against all isolates. Already lemon grass oil was effective only against isolates of Penicillium spp. Conclusions: All genres identified are significant allergens, which can cause respiratory disease in both immunocompromised individuals such as asthmatics and people with any immune deficit. The monitoring of environmental sources should be performed, especially in special areas with immunocompromised patients. Despite efforts to try to reduce fungal infections hospital there are still flaws in the strategies employed.

The main goals for urinary stone treatment are to preserve renal function, reduce or avoid complications related to calculi, and to render the patient free of calculi as soon as possible. Anatrophic nephrolithotomy(ANL) is a valid and useful alternative for conventional staghorn calculi excision. Although excellent stone free rates can be achieved with ANL there are some drawbacks that may be of concern. Morbidity related to intraoperative and postoperative complications isone of them. Another, great concern is the possibility of reduction on renal function related to the procedure itself. This may be related to nephron injury during nephrotomy and parenchymal closure or to ischemic injury. In this review we assess functional results after anatrophic nephrolithotomy.

In the scenery of the oil industry, the remaining resources associated with light oils have an increasingly smaller share in the natural energy resources available to man, and in return the importance of resources associated with heavy oils has increased significantly. One of the drawbacks of this type of oil is associated with its low mobility due to the high viscosity in reservoir conditions, making the transport in pipelines very difficult, especially through pumping methods that require high powers. Thus, the development of new techniques and optimization of some existing technologies, aiming at the commercial use of heavy oil accumulations plays an important role. A viable technique that has been used is the core annular flow, in which small amounts of water are injected close to the pipe wall, lubricating the oil core, reducing friction and decreasing the pressure drop during the flow. In this sense, this work aims to perform, numerically, an energetic and hydrodynamic analysis of a heavy oil-water two-phase flow, using the core-flow technique, in curved pipes, in the Ansys CFX software. Results of the velocity, pressure, and volume fraction distribution of the involved phases are presented and analyzed. It was observed that the proposed mathematical model was able to accurately represent the analyzed phenomena and that a reduction factor in the pressure drop of 28.4 was obtained as compared to the heavy oil single-phase flow.
