ABSTRACT Objective: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). Materials and Methods: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. Results: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. Conclusion: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.

Food additives are chemical substances added to improve organoleptic characteristics, in this context, there are several synthetic dyes, such as sunset yellow, tartrazine, erioglaucine, allura red, indigo carmine, and new coccine, that can also be identified through different analytical techniques such as infrared spectroscopy, UV-Vis spectrophotometry, high performance liquid chromatography with diode array detector and mass spectrometry. Therefore, the objective of this work was to compare methods developed for different analytical techniques, in order to identify the one that presents greater efficiency in certain applications. For this, the patterns of the dyes were analyzed, as well as their mixtures and foods that had them. As a result, the CLAE-DAD presents excellent selectivity and linearity of the calibration curves, but it presents higher LD and LQ values when compared to the UV-Vis, in turn the infrared provides information regarding functional groups and bonds. Mass spectrometry showed great capabilities in identifying the molecular formula and better selectivity in the absence of the erioglaucine dye. It is not feasible to indicate the best or worst analytical approach, but it is possible to point out which one is more suitable for each application. Regarding the quantification capacity, chromatography and UV-Vis are good alternatives, but in mixtures containing more than one dye, CLAE-DAD is more suitable due to the better selectivity. Regarding the identification capacity, mass spectrometry, especially FT-ICR MS, is the most appropriate technique to propose molecular formulas due to its high resolution and mass accuracy. The advantage of FTIR was the easier sample preparation, being able to analyze the dyes in the solid state.

Abstract Background Management delays imply worse outcomes in rheumatoid arthritis (RA) and, therefore, should be minimized. We evaluated changes in diagnostic and treatment delays regarding RA in the last decades in Brazil. Methods Adults fulfilling the ACR/EULAR (2010) criteria for RA were assessed. Delays in diagnosis and treatment, and the frequencies of early management initiation within thresholds (windows of opportunity) of 3, 6, and 12 months from symptoms onset were evaluated. The Mann–Kendall trend test, chi-squared tests with Cramer’s V effect sizes and analysis of variance were conducted. Results We included 1116 patients: 89.4% female, 56.8% white, mean (SD) age 57.1 (11.5) years. A downward trend was found in diagnostic (tau = - 0.677, p < 0.001) and treatment (tau = - 0.695, p < 0.001) delays from 1990 to 2015. The frequency of early management increased throughout the period, with ascending effect sizes across the 3-, 6-, and 12-month windows (V = 0.120, 0.200 and 0.261, respectively). Despite all improvements, even in recent years (2011–2015) the diagnostic and treatment delays still remained unacceptably high [median (IQR): 8 (4–12) and 11 (5–17) months, respectively], with only 17.2% of the patients treated within the shortest, 3-month window. Conclusion The delays in diagnosis and treatment of RA decreased during the last decades in Brazil. Improvements (effect sizes) were greater at eliminating extreme delays (≥ 12 months) than in attaining really short management windows (≤ 3 months). Very early treatment was still an unrealistic goal for most patients with RA.

The study of the spectrum of light has increased its range of action in the field of chemistry, with the help of several advanced equipment and innovative techniques that have become a strong ally of analytical chemistry. However, the simplicity of obtaining results integrated with mobile devices appears as an interesting path to be taken in the field of chemical analysis. This work addresses the dissemination of an application called REDGIM for smartphones on the Android platform capable of working with multivariate image analysis using chemometric methods through the luminous intensities of photos and R (red), G (green) and B (blue) channels. In order to show the potential of REDGIM, we propose two applications using the partial least squares (PLS) regression method: 1) quantification of free chlorine in tap water; and 2) quantification of cannabinol, (CBN, a type of cannabinoid) in marijuana and hashish samples. The free chlorine concentration obtained for two investigated samples was 0.73 and 0.74 mg L-1 and 0.74 and 0.76 mg L-1 by the spectrophotometer and by the application (container: cuvette), respectively. For the quantification of CBN in marijuana and hashish samples, the mean concentration ranged from 6.137 to 8.823 mg mL-1. The results obtained by the application are compatible with results from traditional techniques, such as UV-Vis spectrophotometry, for example. Therefore, REDGIM was proved to be a simple and accessible technological tool for the scientific community, being viable for chemical tests of a multivariate nature.

Abstract Introduction: We investigated the clinical course and outcomes of patients submitted to cardiovascular surgery in Brazil and who had developed symptoms/signs of coronavirus disease 2019 (COVID-19) in the perioperative period. Methods: A retrospective multicenter study including 104 patients who were allocated in three groups according to time of positive real time reverse transcriptase-polymerase chain reaction (RT-PCR) for the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2): group 1, patients who underwent cardiac surgery > 10 days after positive RT-PCR; group 2, patients with a positive RT-PCR within 10 days before or after surgery; group 3, patients who presented positive RT-PCR > 10 days after surgery. The primary outcome was mortality and secondary outcomes were postoperative complications, intensive care unit (ICU) length of stay, and postoperative days of hospitalization. Results: The three groups were similar with respect to age, the European System of Cardiac Operative Risk Evaluation score, and comorbidities, except hypertension. Postoperative complications and death were significantly higher in groups 2 and 3 than in group 1, and no significant difference between groups 2 and 3 was seen. Group 2 showed a high prevalence of surgery performed as an urgent procedure. Although no significant differences were observed in ICU length of stay, total postoperative hospitalization time was significantly higher in group 3 than in groups 1 and 2. Conclusion: COVID-19 affecting the postoperative period of patients who underwent cardiovascular surgery is associated with a higher rate of morbidity and mortality. Delaying procedures in RT-PCR-positive patients may help reduce risks of perioperative complications and death.

Abstract Fusarium oxysporum f. sp. phaseoli (Fop) J.B. Kendrich & W.C. Snyder is the causal agent of Fusarium wilt of common bean (Phaseolus vulgaris L.). The objective of this study was to develop microsatellite markers (SSRs) to characterize the genetic diversity of Fop. Two libraries enriched with SSRs were developed and a total of 40 pairs of SSRs were characterized. Out of these, 15 SSRs were polymorphic for 42 Fop isolates. The number of alleles varied from two to ten, with an average of four alleles per locus and an average PIC (Polymorphic Information Content) of 0.38. The genetic diversity assessed by microsatellites for Fop was low, as expected for an asexual fungus, and not associated with geographic origin, but they were able to detect enough genetic variability among isolates in order to differentiate them. Microsatellites are a robust tool widely used for genetic fingerprinting and population structure analyses. SSRs for Fop may be an efficient tool for a better understanding of the ecology, epidemiology and evolution of this pathogen.

ABSTRACT Purpose To identify how the most frequently used parameters in daily clinical practice diagnosing bladder outlet obstruction (BOO) due to benign prostate hyperplasia (BPH) correlate to each other. Materials and methods The study included 452 patients with lower urinary tract symptoms (LUTS) of the UNICAMP urology outpatient clinic of LUTS. Inclusion criteria: patients with BOO due to BPH who agreed to participate in the study. Exclusion criteria: patients with urinary tract infection, neurological diseases that compromised the lower urinary tract, prior prostatic surgery, radiotherapy or urethral stenosis. Patient assessment: history, international prostate symptoms score (IPSS), nocturnal quality of life score (NQoL) questionnaires, physical and digital rectal examination (DRE), PSA, transabdominal ultrasound with intravesical prostate protrusion (IPP), post-mictional residue and free uroflowmetry. Results There was no strong Spearman correlation among the studied variables. The only moderate correlations occurred between IPSS and NQoL (p <0001; c=0.56) and between IPP and prostate volume (p <0001; c=0.57). Weak correlations between IPP and post-mictional residue (p <0001; c=0.31) and free uroflowmetry (p <0001; c=-0.26); and between IPSS and free uroflowmetry (p <0001, c=-0.21) were observed. Conclusion In this study, we found moderate, weak, very weak and absent correlation among the various parameters used in the diagnosis and management of BOO due to BPH. As the value of these tools is variable, the creation of a logical and objective algorithm was not possible and the treatment is based on the interpretation of clinical symptoms.

ABSTRACT Objective To verify the presence of variants in HNF1B in a sample of the Brazilian population selected according to the presence of renal cysts associated with hyperglycemia. Subjects and methods We evaluated 28 unrelated patients with clinical suspicion of HNF1B mutation because of the concomitant presence of diabetes mellitus (DM) or prediabetes and renal cysts. Genotyping was accomplished using Sanger sequencing or multiplex ligation-dependent probe amplification (MLPA). In positive cases, available relatives were recruited. Results We found two patients with HNF1B mutations. The first presented the variant p.Pro328Leufs*48(c.983delC) and had DM, renal cysts, and hypomagnesemia. The second presented a heterozygous whole gene deletion in HNF1B, DM, renal cysts, body and tail pancreatic agenesis, and hypomagnesemia; this alteration was also found in his two siblings and his father. Conclusion The recruitment of suspected cases of HNF1B gene mutations in Brazilians due to hyperglycemia and renal cysts presents two positive cases. Our cases contribute to the annotation of clinical and biochemical phenotypes of this rare form of maturity-onset diabetes of the young (MODY).

RESUMO: A cana-de-açúcar é um dos principais produtos agrícolas do País, sendo uma das culturas em que mais se utilizam herbicidas. Na safra de 2017/2018 a produção estimada é de 694,54 milhões de toneladas, e se estima um incremento de 0,9% na produtividade para a safra de 2017/2018. Com o objetivo de avaliar o uso de herbicidas nessa cultura no Estado de São Paulo durante cinco anos, foi realizado levantamento junto aos produtores do Estado. A utilização dos herbicidas aplicados isoladamente e em mistura formulada, de acordo com seu mecanismo de ação, foi avaliada entre os anos de 2010 e 2014. Os herbicidas inibidores do fotossistema II foram os mais usados neste período, e a quantidade total dos herbicidas de praticamente todos os mecanismos de ação, exceto inibidores do fotossistema I, aumentou entre os anos de 2010 e 2014. O uso de misturas formuladas de herbicidas também aumentou nesse período. A área tratada por herbicidas inibidores da biossíntese de carotenoides e fotossistema II foi a maior para o controle de espécies da classe das monocotiledôneas (Poaceae, Cyperaceae e Commelinaceae). Em relação à classe das dicotiledôneas, a área tratada por herbicidas inibidores da PROTOX foi a maior em todos os anos avaliados.

ABSTRACT: Sugarcane is one of the main agricultural cultivations of Brazil, and one of the crops in which herbicides are most applied. In the 2017/2018 season, the estimated sugarcane production was 694.54 million tons, with an estimated increase of 0.9% in yield for this season. In order to evaluate the use of herbicides in this crop in the São Paulo State during a five-year period, a survey was carried out with sugarcane farmers. The use of herbicides applied alone and in a formulated mixture, according to their mechanism of action, were evaluated from 2010 to 2014. Photosystem II inhibitor herbicides were the most used in this period and the total amount of herbicides of almost all mechanism of action increased from 2010 to 2014, except for photosystem I inhibitors herbicides. The use of formulated mixtures also increased during this period. The area treated with carotenoid biosynthesis and photosystem II inhibitor herbicides was the largest for the control of monocotyledonous species (Poaceae, Cyperaceae and Commelinaceae). In relation to the dicotyledonous species, the area treated with PROTOX inhibitor herbicides was the largest in all evaluated years.

RESUMO: Este estudo teve como objetivo analisar os casos de mastocitomas cutâneos em cães atendidos no Hospital Veterinário Governador Laudo Natel da Faculdade de Ciências Agrárias e Veterinárias (FCAV) Unesp Câmpus Jaboticabal, no período de 2005 a 2015, além de avaliar a ocorrência dessa neoplasia em relação à raça, sexo e idade; determinar as regiões corpóreas mais acometidas e as características neoplásicas observadas, assim como, os métodos de diagnóstico mais utilizados no setor, estabelecer os principais graus histológicos diagnosticados e os tratamentos preconizados, verificar alterações de tamanho em relação aos linfonodos, à taxa de recidiva, metástase e possíveis associações entre as variáveis consideradas. Foram avaliados 192 prontuários clínicos de pacientes e observou-se que os cães sem raça definida (SRD) (n=46, 23,96%) foram os mais acometidos, seguidos por cães da raça Boxer (n=40, 20,83%) e Pit bull (n=27, 14,06%). A maioria dos cães eram fêmeas (n=107, 55,7%), e com idade de 7 a 11 anos (n=120, 62,5%). Do total, 32 pacientes apresentaram (16,7%) tumores localizados em membro pélvico, seguidos por nódulos em membro torácico (10,4%, n=20). Sessenta e cinco animais possuíam nódulos ulcerados (33,9%), sendo 96 nódulos de consistência firme (50%). Setenta e seis animais apresentavam múltiplos nódulos (39,6%) e aqueles acima de três centímetros perfaziam 39,1% da amostra (n=75). O método mais utilizado para o diagnóstico foi a punção aspirativa por agulha fina associado à histopatologia (HT), totalizando 39,8% dos nódulos (n=66), seguido pela HT com 37,3% (n=62). Em relação às variáveis histológicas, 18 pacientes apresentaram grau I (11,8%), 112 com grau II (73,7%) e 22 com grau III (14,5%) de acordo com Patnaik et al. (1984). Segundo a classificação de Kiupel et al. (2011), 37 casos foram classificados como de alto grau (35,2%) e 68 como sendo de baixo grau (64,8%). Foi observada associação estatística quando se avaliou a presença de nódulos solitários/múltiplos e o grau histológico, segundo Patnaik et al. (1984) (p=0,008) e Kiupel et al. (2011) (p=0,004), sendo que nódulos com piores características prognósticas eram mais frequentes nos animais diagnosticados com múltiplos nódulos, independente da classificação histológica empregada. Também foi observada a associação entre a presença de nódulos múltiplos com estadio II ou IV (p<0,001) e com a presença de recidiva (p=0,001). Em relação à classificação histológica de Kiupel et al. (2011) foi possível observar associação estatística entre o grau histológico e o tamanho do tumor (p=0,001), a consistência (p=0,028) e a velocidade de crescimento do nódulo (p<0,001); aumento de linfonodo (p<0,001) e o tratamento empregado (p=0,002). Nódulos com tamanho superior a três centímetros (56,8%, n=21) e de crescimento rápido (52,9%, n=36%), eram mais frequentes nos tumores de alto grau. Aumento de linfonodo (80,6%, n=25) e tratamento quimioterápico (83,3%, n=5) também estavam associados a pacientes com alto grau histológico. Em relação à classificação de Patnaik et al. (1984), as variáveis raça e sexo diferiram proporcionalmente entre os grupos histológicos (p=0,008 e 0,040 respectivamente), sendo que o aumento do linfonodo e o crescimento rápido do tumor também tiveram associação com o grau histológico (p=0,002 e 0,001). Quase a metade dos pacientes (47,4%) foi submetidas ao tratamento cirúrgico e quimioterápico (n=91), sendo que em 31,3% (n=60) dos pacientes realizou-se apenas o procedimento cirúrgico. Sessenta e um animais (31,8%) apresentaram aumento de tamanho em linfonodos regionais (31,8%), sendo que 71,9% dos nódulos avaliados tiveram crescimento rápido. O tempo de evolução clínica do tumor foi menor ou igual a um ano, em 158 pacientes (82,3%), seguido por 25 pacientes (13%) com evolução de 1 a 2 anos. Foram observados 66 casos (40,5%) de recidiva e 16 (8,3%) de metástase à distância. Com este estudo, pode-se concluir que cães sem raça definida são os mais acometidos pelo mastocitoma cutâneo, na região de Jaboticabal, seguido por cães da raça Boxer, com idade variando entre 7 e 11 anos, não sendo observada predileção sexual; os nódulos encontrados eram predominantemente não ulcerados, solitários e menores que três centímetros; a maioria dos pacientes apresentou mastocitoma grau II, segundo Patnaik et al. (1984) e baixo grau segundo Kiupel et al. (2011); não se observou recidiva, em sua maioria, nem metástase em linfonodos e/ou a distância; o diagnóstico mais utilizado foi a punção aspirativa por agulha fina associada à histopatologia; a localização dos nódulos era mais prevalente nos membros pélvicos e torácicos, seguido por cabeça e pescoço. A consistência dos nódulos era de apresentação firme ou macia; e a metade dos pacientes foi submetida ao procedimento cirúrgico associado à quimioterapia antineoplásica.

ABSTRACT: This study analyzed the cases of cutaneous mastocytomas in dogs seen at the Governador Laudo Natel Veterinary Hospital of the College of Agrarian and Veterinary Sciences (FCAV), Unesp, in Jaboticabal, from 2005 to 2015. The objective was to determine the occurrence of this neoplasm regarding breed, sex, and age, the most affected body parts and observed neoplastic characteristics; the most widely used diagnosis methods, the main histological grades and recommended treatments, to evaluate size changes in relation to lymph nodes, recurrence rate, metastasis and to verify possible associations between the evaluated variables. The clinical files of 192 patients were evaluated. The most affected dogs were of mixed breed (n=46, 23.96%), followed by Boxer (n=40, 20.83%) and Pitbull (n=27, 14.06%). Most of the dogs were females (n=107, 55.7%), aged between 7 and 11 years old (n=120, 62.5%). Thirty-two patients had (16.7%) tumors located in the pelvic limb, followed by thoracic limbs (10.4% n=20). Sixty-five animals had ulcerated nodules (33.9%), of which 96 had firm consistency (50%). Seventy-six animals had multiple nodules (39.6%), and 39.1% of the sample (n=75) had nodules larger than three centimeters. The most used diagnosis method was fine needle aspiration together with histopathology (HT), totaling 39.8% of nodules (n=66), followed by HT in 37.3% of the patients (n=62). Regarding the histological variables, 18 patients had grade I (11.8%), 112 grade II (73.7%), and 22 grade III (14.5%) classified according to Patnaik et al. (1984). According to the classification of Kiupel et al. (2011) 37 cases were classified as high grade (35.2%) and 68 as low grade (64.8%). Statistical association was observed when the presence of solitary/multiple nodules and the histological grade were evaluated according to Patnaik et al. (1984) (P=0.008) and Kiupel et al. (2011) (P=0.004). The nodules with worse prognostic feature were more frequent in animals diagnosed with multiple nodules, regardless of the histological classification used. The presence of multiple nodules in stage II or IV (p<0.001) and recurrence of the disease (p=0.001) was also observed. Regarding the histological classification of Kiupel et al. (2011), there was a statistical association between histological grade and tumor size (p=0.001), consistency (p=0.028) and nodule growth rate (p<0.001), lymph node enlargement (p<0.001) and the treatment used (p=0.002). Nodules larger than three centimeters (56.8% n=21) and fast growing (52.9% n=36%) were more frequent in high-grade tumors. Lymph node enlargement (80.6% n=25) and chemotherapeutic treatment (83.3% n=5) were also associated with patients with this histological grade. According to the classification of Patnaik et al. (1984), breed and sex differed proportionally between the histological groups (p=0.008 and 0.040 respectively), and lymph node enlargement and rapid tumor growth were also associated with histological grade (p=0.002 and 0.001). Almost half of the patients (47.4%) underwent surgical and chemotherapeutic treatment (n=91) while only surgical procedure was performed in 31.3% (n=60) of the patients. Sixty-one animals (31.8%) had enlarged regional lymph nodes (31.8%), and 71.9% of the nodes evaluated had rapid growth. The clinical evolution time of the tumor was less than or equal to one year in 158 patients (82.3%), followed by 1 to 2 years in 25 patients (13%). There were 66 cases (40.5%) of recurrence and 16 (8.3%) of distant metastasis. With this study, it can be concluded that dogs with mixed breed are the most affected by cutaneous mastocytoma in Jaboticabal city, followed by Boxer dogs, with ages varying between 7 and 11 years, with no sexual predisposition observed. It was also concluded that nodules were predominantly non-ulcerated, solitary and smaller than 3 centimeters, that the majority of patients presented grade II mastocytoma according to Patnaik et al. (1984) and low grade according to Kiupel et al. (2011), not being observed in most of them recurrence, lymph node or distance metastasis. The most commonly used diagnosis was fine-needle aspiration associated with histopathology, and in relation to location, nodules were found predominantly in pelvic and thoracic limbs, followed by head and neck. The consistency of the nodules was both firm and soft, and half of the patients underwent the associated surgical procedure of antineoplastic chemotherapy.

Resumo: Paisagens antropicamente modificadas (HMLs) são compostas por fragmentos florestais pequenos, isolados e defaunados, imersos em áreas agrícolas e/ou urbanas. Informações sobre as espécies que habitam essas paisagens são importantes para o direcionamento de estratégias de conservação em escalas local e regional. Uma vez que as HMLs são as paisagens dominantes na Mata Atlântica, o objetivo deste trabalho foi avaliar a diversidade de mamíferos em uma HML do sudeste do Brasil e propor estratégias para sua conservação. Foram coletados dados de mamíferos terrestres (pequenos, médios e grandes) e voadores em três fragmentos florestais (10, 14 e 26 ha) e áreas adjacentes, entre 2003 e 2016, usando métodos complementares: busca ativa, armadilhamento fotográfico, armadilhas de captura e redes de neblina. Adicionalmente, foram utilizados dados de literatura para complementar a lista de espécies. Foram registradas 35 espécies de mamíferos nativos (6 de pequenos, 16 de médios e grandes e 13 de morcegos) e sete espécies exóticas. A assembleia de mamíferos registrada (terrestres e voadores), embora composta por espécies generalistas, apresentou três espécies de médio e grande porte ameaçadas de extinção nacionalmente (Leopardus guttulus, Puma concolor and Puma yagouaroundi) e duas deficientes em dados (Galictis cuja and Histiotus velatus), destacando a importância dessa HML para conservação e manutenção das populações de mamíferos. Embora inserida em uma paisagem extremamente modificada, a área de estudo abriga uma riqueza significativa de mamíferos de médio e grande porte, sendo um importante refúgio para a biodiversidade na região. Entretanto, essa biodiversidade está ameaçada pela baixa qualidade dos habitats, por atropelamentos e por abundantes populações de cães e gatos domésticos. Portanto, enfatizamos a necessidade de estratégias de conservação focadas nos mamíferos de médio e grande porte como grupo "guarda-chuva", o que pode beneficiar as demais espécies na paisagem. Recomendamos ações de conservação visando a restauração biológica, para melhorar a composição estrutural e conectividade dos fragmentos florestais, reduzir o número de atropelamentos e controlar as populações de cães e gatos domésticos, afim de manter e aumentar a diversidade local de mamíferos em longo prazo.

Abstract: Human-modified landscapes (HMLs) are composed by small, isolated and defaunated forest fragments, which are surrounded by agricultural and urban areas. Information on species that thrives in these HMLs is essential to direct conservation strategies in local and regional scales. Since HMLs are dominant in the Atlantic Forest, we aimed to assess the mammalian diversity in a HML in southeastern Brazil and to propose conservation strategies. We collected data of terrestrial (small-, medium- and large-sized) and volant mammals in three small forest fragments (10, 14 and 26 ha) and adjacent areas, between 2003 and 2016, using complementary methods: active search, camera trapping, live-traps, mist nets and occasional records (i.e., roadkills). In addition, we used secondary data to complement our species list. We recorded 35 native mammal species (6 small-sized, 16 medium- and large-sized, and 13 bats) and seven exotic species in the HML. The recorded mammal assemblage (non-volant and volant), although mainly composed of common and generalist species, includes three medium- and large-sized species nationally threatened (Leopardus guttulus, Puma concolor and Puma yagouaroundi) and two data deficient species (Galictis cuja and Histiotus velatus), highlighting the importance of this HML for the maintenance and conservation of mammal populations. Despite highly impacted by anthropogenic disturbances, the study area harbors a significant richness of medium- and large-sized mammals, being an important biodiversity refuge in the region. However, this biodiversity is threatened by the low quality of the habitats, roadkills and abundant populations of domestic cats and dogs. Therefore, we stress the need of conservation strategies focusing on the medium- and large-sized mammals as an umbrella group, which could benefit all biodiversity in the landscape. We recommend actions that promotes biological restoration, aiming to increase structural composition and connectivity of the forest fragments, reducing roadkills and controlling the domestic cats and dogs' populations, in order to maintain and improve the diversity of mammals in long-term.

ABSTRACT Rhodococcus equi is a facultative aerobic, intracellular, non-motile, non-spore-forming, Gram-positive, weakly acid-fast coccobacillus belonging to the group of nocardioform actinomycetes. R. equi infections are rare opportunistic illnesses in patients with Acquired Immunodeficiency Syndrome (AIDS), associated with a high mortality rate. The most common clinical presentation of R. equi infections is a chronic cavitary pneumonia. Due to its acid-fastness, R. equi can be mistaken for others acid-fast organisms, as Mycobacterium tuberculosis. In turn, R. equi is also a gram-positive pleomorphic bacteria and can be mistaken for diphtheroids or Micrococcus organisms, being accidentally disregarded as oral contaminants in sputum cultures. Therefore, in Brazil, a highly prevalent tuberculosis (TB) country, pulmonary infections caused by R. equi may mimic pulmonary TB and represent a diagnostic challenge. Here, we report on a case of chronic cavitary pneumonia by R. equi in a Human Immunodeficiency Virus (HIV)-infected patient, focusing on diagnostic aspects.

ABSTRACT Objective: To evaluate the overactive bladder (OAB) diagnosis using OAB-V8 and ICIQOAB questionnaires in women with different schooling and cultural levels. Materials and Methods: Three hundred and eighty six healthy women answered a clinical questionnaire filling out information about schooling, demographic and gynecological data. The OAB-V8 and ICIQ-OAB questionnaires were used to evaluate OAB diagnosis and symptoms; and the QS-F questionnaire, to determine the sexual function. All questionnaires were validated in Portuguese. Results: The mean age was 37.3 years-old. Regarding to schooling level, 23.1% had concluded primary education; 65.8%, secondary school; and 11.1% had higher education. Considering the OAB-V8 (score ≥8), 51.8% of evaluated women had OAB diagnosis. There was a positive linear correlation between the OAB-V8 and ICIQ-OAB questionnaires in its sections “a” (r=0.812, p<0.001) and “b” (r=759, p<0.001). There was a positive linear correlation between age and the amount of time used to answer the OAB-V8, ICIQ-OAB and QS-F questionnaires (p<0.001). The ICIQ-OAB was the hardest to answer for all schooling levels when compared to the other questionnaires. Women who had concluded primary and secondary education significantly demanded more help to answer all questionnaires than those with higher education (p<0.05). Furthermore, women with higher education took significantly less time answering all questionnaires when compared to their less educated counterparts (primary and secondary schooling), since they were quicker to answer each individual question. Conclusion: Educational level and ageing had an impact on women response using different questionnaires for OAB and sexual function evaluations.
