Adherence to antiretroviral treatment and quality of life among transgender women living with HIV/AIDS in São Paulo, Brazil.

This study focused on factors associated with antiretroviral therapy (ART) adherence and quality of life among transgenderwomen in Sao Paulo, Brazil, using univariable and adjusted analysis. Adherence was evaluated with a self-report tool and with HIV viral load (VL) measurement. PROQOL-HIV was used to assess quality of life. 106 TGW with median 41 years old were included; most were white (56%) and had >10 years of education (57%). Median time since HIV/AIDS diagnosis was 10 years. Overall, participants had high T CD4+ counts (median 659 cells/mm3) and most (75%) had undetectable HIV VL. 85% were considered adherent using self-report (95%CI 77-91), whereas 72% (95%CI 62-80) were considered adherent when self-report and undetectable HIV VL were analyzed jointly. Older age was associated with higher ART adherence; each year increase in age was associated with 5% higher odds of adherence (p = 0.021). Quality of life ranged from good-excellent in 5 of 8 domains. Younger age, lower education, higher time since HIV diagnosis, comorbidities, illicit drugs use and depression were associated with lower PROQOL scores in specific domains in univariable analysis, while depression was also associated with lower total PROQOL score even after adjustment for age, comorbidities and time since HIV diagnosis (p = 0.048).

Hemodialysis and Kidney Transplantation as Predisposing Conditions to Onychomycosis.

BACKGROUND/AIM: Onychomycosis (OM) is one of the commonest superficial fungal infections. Patients undergoing hemodialysis (HD) treatment and kidney transplant recipients (KTR) are considered at risk of contracting fungal infections, but the few published data do not reach the conclusion of whether they are predisposed to OM. This study aimed to determine the prevalence and etiology of OM in these patients and to determine the antifungal susceptibility profile of the isolated fungal species. METHODS: We recruited 149 HD patients, 187 KTR, and a control group comprising 174 patients attending an internal medicine service with other diseases than renal diseases. All patients underwent an examination of all toenails to check for the presence of OM. Antifungal susceptibility tests were performed following the Clinical and Laboratory Standards Institute (CLSI) recommendations. RESULTS: The prevalence rates of OM in HD patients (23.4%) and KTR (23.0%) were significantly higher than those in age- and sex-matched control groups (13.2%). In HD patients, OM was associated with diabetes but not with the duration of dialysis. In KTR, OM was more prevalent in those without diabetes and likely also in those using mycophenolate mofetil or azathioprine but was not associated with the duration of transplantation. Trichophyton rubrum was the most prevalent species (45.9%) followed by T. mentagrophytes (24.5%) and Candida parapsilosis (18.0%). Fluconazole, itraconazole, voriconazole, and terbinafine were all efficient against the isolates of dermatophyte, with terbinafine showing the lowest and fluconazole the highest minimal inhibitory concentrations. All isolates of C. parapsilosis were sensitive to the antifungals according to the CLSI criteria. CONCLUSION: We found a high prevalence of OM in HD and KTR patients and suggest that these conditions should be considered a risk factor of OM. All 4 antifungals evaluated in the study showed good in vitro activity against the etiologic agents.

Polymorphisms in the p27kip-1 and prohibitin genes denote novel genes associated with melanoma risk in Brazil, a high ultraviolet index region.

Ultraviolet (UV) radiation is a major environmental risk factor to the development of cutaneous melanoma as it induces pyrimidine dimers in DNA. Genes that exert their function by arresting the cell cycle are critical to avoid carcinogenic mutations, allowing the processing of DNA repair systems. This study was carried out to evaluate the role of polymorphisms in cell cycle genes such as TP53, p27, CDKN2A, prohibitin, and GADD153 in melanoma risk as well as their influence on known risk factors in a high UV index region. A hospital-based case-control study was carried out in Brazil to evaluate the contribution of polymorphisms in cell cycle genes toward melanoma risk. The study comprised 202 melanoma patients and 210 controls. The polymorphisms analyzed were TP53 Arg72Pro, p27 Val109Gly, GADD153 Phe10Phe (rs697221), CDKN2A 3'UTR C540G, and prohibitin 3'UTR C1703T. As regards, p27 Val109Gly, both heterozygous and homozygous Gly genotypes were shown to be protective genotypes on calculating both crude and adjusted odds ratios (ORs) for age, sex, and educational level [OR 0.37; 95% confidence interval (CI) 0.16-0.87; P<0.05]. Similarly, the prohibitin TT genotype increased melanoma risk in the crude and adjusted analyses (OR 2.40; 95% CI 1.10-5.26; P<0.05). The p27 Gly protective genotype decreased the risk for melanoma in a stratified analysis of the known risk factors such as hair and eye color, sunburns, pigmented lesions, and European ancestry. The prohibitin TT genotype increased the risk of melanoma by such host factors. Our results showed for the first time that polymorphisms in p27 Val109Gly and in prohibitin 3'UTR C1703T genotypes modulate the risk to melanoma in a high UV index region.

Ethnicity and cutaneous melanoma in the city of Sao Paulo, Brazil: a case-control study.

BACKGROUND: Over the last century the incidence of cutaneous melanoma has increased worldwide, a trend that has also been observed in Brazil. The identified risk factors for melanoma include the pattern of sun exposure, family history, and certain phenotypic features. In addition, the incidence of melanoma might be influenced by ethnicity. Like many countries, Brazil has high immigration rates and consequently a heterogeneous population. However, Brazil is unique among such countries in that the ethnic heterogeneity of its population is primarily attributable to admixture. This study aimed to evaluate the contribution of European ethnicity to the risk of cutaneous melanoma in Brazil. METHODOLOGY/PRINCIPAL FINDINGS: We carried out a hospital-based case-control study in the metropolitan area of Sao Paulo, Brazil. We evaluated 424 hospitalized patients (202 melanoma patients and 222 control patients) regarding phenotypic features, sun exposure, and number of grandparents born in Europe. Through multivariate logistic regression analysis, we found the following variables to be independently associated with melanoma: grandparents born in Europe-Spain (OR = 3.01, 95% CI: 1.03-8.77), Italy (OR = 3.47, 95% CI: 1.41-8.57), a Germanic/Slavic country (OR = 3.06, 95% CI: 1.05-8.93), or ≥ 2 European countries (OR = 2.82, 95% CI: 1.06-7.47); eye color-light brown (OR = 1.99, 95% CI: 1.14-3.84) and green/blue (OR = 4.62; 95% CI 2.22-9.58); pigmented lesion removal (OR = 3.78; 95% CI: 2.21-6.49); no lifetime sunscreen use (OR = 3.08; 95% CI: 1.03-9.22); and lifetime severe sunburn (OR = 1.81; 95% CI: 1.03-3.19). CONCLUSIONS: Our results indicate that European ancestry is a risk factor for cutaneous melanoma. Such risk appears to be related not only to skin type, eye color, and tanning capacity but also to others specific characteristics of European populations introduced in the New World by European immigrants.

European ancestry and polymorphisms in DNA repair genes modify the risk of melanoma: a case-control study in a high UV index region in Brazil.

BACKGROUND: UV radiation is the major environmental factor related to development of cutaneous melanoma. Besides sun exposure and the influence of latitude, some host characteristics such as skin phototype and hair and eye color are also risk factors for melanoma. Polymorphisms in DNA repair genes could be good candidates for susceptibility genes, mainly in geographical regions exposed to high solar radiation. OBJECTIVE: Evaluate the role of host characteristics and DNA repair polymorphism in melanoma risk in Brazil. METHODS: We carried out a hospital-based case-control study in Brazil to evaluate the contribution of host factors and polymorphisms in DNA repair to melanoma risk. A total of 412 patients (202 with melanoma and 210 controls) were analyzed regarding host characteristics for melanoma risk as well as for 11 polymorphisms in DNA repair genes. RESULTS: We found an association of host characteristics with melanoma development, such as eye and hair color, fair skin, history of pigmented lesions removed, sunburns in childhood and adolescence, and also European ancestry. Regarding DNA repair gene polymorphisms, we found protection for the XPG 1104 His/His genotype (OR 0.32; 95% CI 0.13-0.75), and increased risk for three polymorphisms in the XPC gene (PAT+; IV-6A and 939Gln), which represent a haplotype for XPC. Melanoma risk was higher in individuals carrying the complete XPC haplotype than each individual polymorphism (OR 3.64; 95% CI 1.77-7.48). CONCLUSIONS: Our data indicate that the host factors European ancestry and XPC polymorphisms contributed to melanoma risk in a region exposed to high sun radiation.

O programa de saúde da família e a gravidez na adolescência em São Bernardo do Campo / The family health program and the teenage pregnancy in São Bernardo do Campo

O PSF/IPACS (Programa Saúde da Família) foi criado em 1994 quando se formaram as primeiras equipes de saúde da família com o propósito de reorganizar a prática da atenção à saúde. Dentre as atuações do PSF/PACS está a prevenção da gravidez na adolescência. A gravidez na adolescência é motivo de preocupação das organizações de saúde nacionais e internacionais pelas repercussões físicas, psicológicas e sociais deste fenômeno na sociedade atual. O objetivo do presente trabalho foi comparar a proporção de gravidez na adolescência entre a população total de São Bernardo do Campo e a população coberta pelo PSF/PACS na mesma cidade. A população menor de 20 anos coberta pelo PSF/PACS de São Bernardo do Campo apresentou uma porcentagem de gravidez na adolescência significativamente menor que na população de São Bernardo sem assistência do PSF/PACS nos anos de 1999 a 2002. Isso indica que possivelmente o PSF/PACS através de seus mecanismos de prevenção da gravidez na adolescência esteja obtendo resultados positivos. No entanto, faz-se necessário acompanhamento prolongado para uma conclusão mais definitiva.
