Sigla em inglês utilizada pelos próprios transexuais e também na literatura médica para designar o que tenho chamado de 'homem trans'. Literalmente significa female-to-male, feminino para masculino'. Resumo Apresentação Apresentação Apresentação Apresentação ApresentaçãoElegi discutir o que percebi como recorrente em meio à diversidade do microcosmo de 'homens trans' a que tenho tido acesso, também ele marcado por dissidências e conformações, como sugere o título deste dossiê.Para efeito deste artigo, considero como equivalentes as categorias empíricas "homem transexual", "homem trans", "transhomem", "transman", "FTM" 1 ou "transexual masculino". Dessa forma, para evitar o uso de múltiplas expressões, utilizarei o termo "homem trans" no esforço de condensar a experiência da 'transexualidade masculina'. Tomo a autodenominação a partir das categorias acima, como critério de nomeação.

The emergence of less common fungal pathogens has been increasingly reported in the last decade. We describe 25 cases of Rhodotorula spp. isolated from blood cultures at a large Brazilian tertiary teaching hospital from 1996-2004. We also investigated the in vitro activity of four antifungal drugs, using a standardized method. The median age of patients was 43 years. The majority of patients (88%) had a central venous catheter (CVC) and 10 (40%) were recipients of a bone marrow transplant. The episode was classified as a bloodstream infection (BSI) in 80% of the patients. Amphotericin B deoxycholate was the most common antifungal used and CVC was removed in 89.5% of the patients. Death occurred in four patients (17.4%), all classified as BSI. All strains were identified as R. mucilaginosa by conventional methods. Misidentification of the species was observed in 20% and 5% of the strains with the Vitek Yeast Biochemical Card and API 20C AUX systems, respectively. Amphotericin B demonstrated good in vitro activity (MIC50/90, 0.5 microg/ml) and the MICs for fluconazole were high for all strains (MIC50/90, >64 microg/ml).

The pathophysiology of oropharyngeal candidiasis in patients infected with human immunodeficiency virus (HIV) type 1 is poorly understood. Association between oropharyngeal yeast carriage and various clinical factors in HIV-1-infected patients was studied in 83 patients with no clinical evidence of thrush and no recent antifungal use. Of the clinical factors measured, the only correlate of yeast colonization was with plasma HIV-1 RNA levels (P=.001), whereas the correlation with CD4 cell count was poor (P=.36). By multivariable regression modeling, plasma HIV-1 RNA was the only parameter that correlated with the extent of colonization with Candida infection (P=.003). These data indicate that the presence and amount of asymptomatic oropharyngeal yeast carriage in persons with HIV-1 infection is more significantly correlated with plasma HIV-1 RNA levels than with CD4 cell count. Further studies on the effect of HIV-1 on oropharyngeal yeast colonization, infection, and local immunity are warranted.

Rhodotorula spp. are emergent opportunistic pathogens, particularly in immunocompromised individuals. They have been associated with endocarditis, peritonitis, meningitis endophthalmitis and catheter-associated fungemia. The aim of this study was to review all cases of central venous catheter-related fungemia due to Rhodotorula spp. reported in the literature in order to determine the best management of this uncommon infection. All patients but one in the 88 cases examined had some form of underlying disease including sixty-nine (78.4%) who had cancer. Rhodotorula mucilaginosa was the species most frequently recovered (75%), followed by Rhodotorula glutinis (6%). Amphotericin B deoxycholate was the most common antifungal agent used as treatment and the overall mortality was 9.1% in this review. This fungemia is a rare disease which can be found in immunocompromised and in the intensive care patients. The use of specific antifungal therapy may be associated with an increase in the survival. It should be noted that Rhodotorula spp. is resistant to fluconazole.

Introduction: Although the spectrum of fungi causing bloodstream fungal infections continues to expand, Candida spp. remains responsible for the majority of these cases. Objective: The purpose of this study was to characterize the candidemia epidemiology, species distribution and antifungal susceptibility patterns at a Brazilian tertiary teaching public hospital with 2,500 beds. Methods: Records from the microbiology laboratory were used to identify patients with positive blood cultures during 2006. The in vitro activity of amphotericin B, caspofungin, itraconazole, fluconazole, voricanozole, and posaconazole were determined using the Etest method. Results: One hundred and thirty-six cases of candidemia were identified and 100 strains were available for antifungal susceptibility testing. The overall incidence of candidemia was 1.87 cases/1.000 admissions and 0.27 cases/1.000 patient-days. Among the patients, 58.1% were male, and the median age was 40 years old. C. albicans was the most common species (52.2%), followed by C. parapsilosis (22.1%), C. tropicalis (14.8%), and C. glabrata (6.6%). All strains were susceptible to amphotericin B with a MIC 90 of 0.5 µg/mL. Overall susceptibility for voriconozole, fluconazole, and caspofungin was ≥ 97% with a MIC 90 of 0.064, 4.0 and 1.0 µg/mL, respectively. For itracona-zole the susceptibility rate was 81% with a MIC 90 of 0.5 µg/mL. Posaconazole also demonstrated good in vitro activity with a MIC 90 of 0.25 µg/mL. Conclusion: This is the first antifungal susceptibility report in our institution.

A produção acadêmica motivada pela epidemia de HIV e Aids impulsionou as pesquisas relativas à sexualidade, configurando novos campos de investigação, em especial sobre os "gays". No entanto, não é significativa no Brasil a produção acadêmica que aborde a vulnerabilidade às DSTs a partir da identidade "lésbica". A saúde sexual das mulheres presumidamente heterossexuais tendeu a permanecer subsumida à exclusiva preocupação com a reprodução ao longo da trajetória das políticas de atenção à saúde das mulheres, mesmo frente à Aids. De forma ainda mais acentuada que a sexualidade feminina heterossexual, a homossexualidade feminina tendeu à invisibilidade na sociedade brasileira e frente ao discurso médico-ginecológico. O advento da epidemia contribuiu para a manutenção desta invisibilidade, por força da crença de que o "corpo lésbico" seria o único corpo infenso à infecção pela via sexual. A hipótese que norteou o presente trabalho está calcada na ideia de que a vulnerabilidade das lésbicas é o "passaporte" para a afirmação/inclusão de um dado marco identitário na agenda de políticas públicas.

Polyhalite (PH) is a hydrated sulfate evaporite mineral containing potassium, calcium, magnesium, and sulfur, nutrients all required in significant quantities by crops, but has limited evaluation as a fertilizer for potato (Solanum tuberosum L.). Fertilizer source and application rate field trials were conducted to evaluate PH as a fertilizer for potato production in the weathered tropical soils in Brazil. We selected two locations in the potato producing region of Southeast Brazil in 2015–16, one trial was conducted during the wet season at Tapira in São Paulo and the other during the winter season at Casa Branca in Minas Gerais. A common blend, 4–14–8, was made with either muriate of potash (MOP), sulfate of potash (SOP), or PH as the K source; with kieserite and gypsum added to the SOP to make a synthetic PH with similar composition; P either as single super phosphate (SSP) for the MOP blend or mono ammonium phosphate (MAP) for the PH and SOP blends; and N as urea adjusted for the N in MAP. All blends were applied at four application rates of 62, 125, 187, and 249 kg K/ha. A control was also included consisting of N and P as urea and MAP but no K, Ca, Mg, or S. Total and marketable yields as well as potato quality including dry matter, starch, soluble solids, hardness, and crunchiness were measured at harvest using standard techniques. At Tapira, potato yields increased linearly with increasing K application rate from 22.4 t·ha−1 for the control to the highest yield of 29.2 t·ha−1 and were higher for PH and SOP than MOP (28.8, 29.2, and 25.3 t·ha−1, respectively). At Casa Branca, yields increased from 31.5 t·ha−1 for the control to 42.4 kg·ha−1 at the 62 kg K/ha application rate with no further increases at higher rates and no differences among fertilizer blends at any application rate. Polyhalite blend increased dry matter and starch at the higher application rates compared with MOP and SOP at Tapira and increased potato hardness and crunchiness at the optimum 62 kg K/ha application rate at Casa Branca. Yield response was similar for PH and SOP but quality differences between these two fertilizer blends were observed even though they were similar in composition. Differences between PH and MOP may be related either to Cl or lack of Mg in the MOP blend. PH performed well as a fertilizer for potatoes as it produced equal or higher yields and provided benefits to potato quality when compared with MOP or SOP as a K source in a common fertilizer blend.
