Efficacy of tailored messages to improve behavioral intent to accept HPV vaccination among mothers may be moderated by sociodemographics.

We assessed differences in response to a tailored recommendation intervention for HPV vaccine by participants' sociodemographic characteristics in this exploratory sub-analysis of a larger web-based, randomized-controlled trial on tailored messaging among mothers with low intent to vaccinate their 11-14-year-old child against HPV. The intervention consisted of pre-recorded video messages tailored to 1-5 common concerns about HPV vaccine. In these exploratory analyses, we used generalized linear models to assess differences in post-intervention intent across intervention arms, stratified by sociodemographic characteristics among 496 trial participants. We found significantly higher post-intervention intent in the intervention participants versus the control group among mothers: 1) with younger children; 2) with white vs. black children; 3) with Non-Hispanic children; 4) who were younger; 5) with some college or vocational training; with household incomes of ≥$100,000; and 7) with 1-2 children. Our findings of effect modification by certain sociodemographic factors such as age, race/ethnicity, and household income should be considered when designing similar tailored messaging interventions.

Pelvic radiation therapy with volumetric modulated arc therapy and intensity-modulated radiotherapy after renal transplant: A report of 3 cases.

AIM: Describe characteristics and outcomes of three patients treated with pelvic radiation therapy after kidney transplant. BACKGROUND: The incidence of pelvic cancers in kidney transplant (KT) recipients is rising. Currently it is the leading cause of death. Moreover, treatment is challenging because anatomical variants, comorbidities, and associated treatments, which raises the concern of using radiotherapy (RT). RT has been discouraged due to the increased risk of urethral/ureteral stricture and KT dysfunction. MATERIALS AND METHODS: We reviewed the electronic health records and digital planning system of patients treated with pelvic RT between December 2013 and December 2018 to identify patients with previous KT. CASES DESCRIPTION: We describe three successful cases of KT patients in which modern techniques allowed full standard RT for pelvic malignances (2 prostate and 1 vaginal cancer) with or without elective pelvic nodal RT, without allograft toxicity at short and long follow-up (up to 60 months). CONCLUSION: When needed, RT modern techniques remain a valid option with excellent oncologic results and acceptable toxicity. Physicians should give special considerations to accomplish all OAR dose constraints in the patient's specific setting. Recent publications recommend KT mean dose <4 Gy, but graft proximity to CTV makes this unfeasible. We present 2 cases where dose constraint was not achieved, and to a short follow-up of 20 months renal toxicity has not been documented. We recommend the lowest possible mean dose to the KT, but never compromising the CTV coverage, since morbimortality from recurrent or progressive cancer disease outweighs the risk of graft injury.

Anal cancer screening in a high-risk behavior group: A local picture / Rastreamento de câncer anal em um grupo de comportamento de alto risco: uma imagem local

ABSTRACT Study objectives To perform anal lesion and anal cancer screening in men living with HIV/AIDS. Methods This is a descriptive, observational, cross-sectional study. Data were obtained from the Specialized Assistance Service (SAE) in Divinópolis, Minas Gerais. A sociodemographic, epidemiological, and sexual behavior questionnaire was applied; material was collected for cytology, high-resolution anoscopy (AAR) was performed, and an acceptability questionnaire applied. Main results Of the 50 men living with HIV/AIDS invited to participate in this study, 6% were excluded because they were illiterate, 40% refused to participate, and 54% participated in the survey. Among these, all answered the self-administered questionnaire. However, ten (37.0%) underwent proctological examination and anal cytology. Of these, two did not respond to the acceptability questionnaire. No anal lesions were identified during AAR and no biopsy was required. A 10% change in anal cytology was found. Conclusions Through the study it was possible to construct a flow of referrals from the SAE to the UFSJ Coloproctology outpatient clinic. Moreover, the existence of internal stigmas on the part of the participants regarding the proctological examination and the lack of information about anal cancer screening are challenges to be overcome.

RESUMO Objetivos do estudo Realizar o rastreamento de lesões anais e câncer anal em homens vivendo com HIV/AIDS. Métodos Trata-se de estudo descritivo observacional transversal, cujos dados foram obtidos no Serviço de Assistência Especializada (SAE) em Divinópolis, Minas Gerais. Foi aplicado questionário sociodemográfico, epidemiológico e de comportamento sexual; realizada coleta de material para citologia, Anuscopia de Alta Resolução (AAR) e aplicado questionário de aceitabilidade do exame. Principais resultados Dos 50 homens vivendo com HIV/AIDS convidados a participar do presente estudo, 6% foram excluídos por serem analfabetos, 40% se recusaram a participar e 54% participaram da pesquisa. Entre estes, todos responderam o questionário autoaplicado. Entretanto, 10 (37.0%) realizaram o exame proctológico e a citologia anal. Desses, dois não responderam ao questionário de aceitabilidade. Não foram identificadas lesões anais durante a AAR, não sendo necessária a realização de biópsia. Foi encontrado 10% de alteração à citologia anal. Conclusões Por meio do estudo foi possível construir um fluxo de encaminhamentos do SAE para o ambulatório de Coloproctologia da UFSJ. Ademais, a existência de estigmas internos por parte dos participantes no que concerne à realização do exame proctológico e a falta de informação a respeito do rastreamento do câncer anal são desafios a serem vencidos.

Hand warts among butchers in a supermarket in São Paulo.

BACKGROUND: Butchers are exposed to biological hazards as a function of their continuous handling of meat containing blood, fat and fluids. Biological hazards include contamination with viruses, such as the papillomavirus (HPV), especially HPV type 7, which is associated with the so-called "butcher's wart." OBJECTIVE: To investigate wart-like lesions among meat handlers. METHOD: Cross-sectional descriptive study conducted at a supermarket in São Paulo in 2017. Twenty-four employees allocated to the meat handling section were interviewed and subjected to skin visual examination; lesions were photographed. RESULTS: Most participants were male (87.5%) and half of them (50.0%) were within age range 31 to 40 years old. Only one employee had started working in this section less than 2 years earlier. Wart-like lesions or scars with black dots on their center were found on the hands of 11 butchers (45.8%). CONCLUSION: Almost half of the participants had history of hand warts. Most of the participants with lesions were male, aged up to 40, right-handed and had worked as meat handlers for 2 years at least. We might infer we found cases of wart-like occupational dermatosis among butchers at a supermarket in São Paulo.

INTRODUÇÃO: A profissão de açougueiro é descrita como exposta a agentes de risco biológico, devido à manipulação constante de carne com sangue, gorduras e fluidos. Entre os riscos biológicos, podemos encontrar contaminação por agentes virais como o papilomavírus (HPV), mais predominantemente o HPV de subtipo 7, caracterizado como "verruga do açougueiro". OBJETIVO: O objetivo do estudo é avaliar a presença de lesões verrucosas em trabalhadores do setor de açougue. MÉTODO: Este estudo transversal descritivo foi realizado em um supermercado na cidade de São Paulo durante o ano de 2017. Participaram 24 trabalhadores do setor de açougue: todos responderam a uma entrevista e foram submetidos à inspeção da pele, e as lesões encontradas foram documentadas por foto. RESULTADOS: A maioria dos participantes é homem (87,5%) e metade deles (50,0%) estava na faixa etária de 31 a 40 anos. Apenas um funcionário iniciou no setor há menos de dois anos (4,2%). Lesões como verrugas ou cicatrizes de lesões com ponto preto em região central foram encontradas nas mãos de 11 açougueiros (45,8%). CONCLUSÃO: Quase metade dos participantes apresentavam sinais de história de verrugas em mãos. O grupo de lesionados tinha maioria do sexo masculino, idade até 40 anos, eram destros e trabalhavam no açougue há pelo menos dois anos. Podemos sugerir que foram detectados casos de dermatoses ocupacionais de verrugas em trabalhadores no açougue de supermercado na cidade de São Paulo.

Immunogenicity assessment of HPV16/18 vaccine using the glutathione S-transferase L1 multiplex serology assay.

The glutathione S-transferase (GST)-L1 multiplex serology assay has favorable properties for use in clinical trials and epidemiologic studies, including low cost, high throughput capacity, and low serum volume requirement. Therefore, we evaluated the GST-L1 assay as a measure of HPV16/18 vaccine immunogenicity. Our study population included 65 women selected from the Costa Rica Vaccine Trial who received the bivalent HPV16/18 virus-like particle (VLP) vaccine at the recommended 0/1/6-month schedule. We tested replicate serum samples from months 0/1/12 (i.e., after 0/1/3 doses) by GST-L1 and 3 other commonly used serology assays, VLP-ELISA, SEAP-NA, and cLIA. We calculated the percentage of women seropositive by GST-L1 by time point and HPV type (14 HPV types), and compared GST-L1 to other assays using Spearman rank correlation coefficients. After 1 vaccine dose, seropositivity by GST-L1 was 40% each for HPV16 and HPV18, increasing to 100% and 98%, respectively, after 3 doses. Seropositivity after 3 doses ranged from 32% to 69% for HPV types 31/33/45, for which partial vaccine efficacy is reported, though increases also occurred for types with no evidence for cross-protection (e.g., HPV77). GST-L1 correlated best after 3 doses with VLP-ELISA (HPV16 and HPV18 each ρ = 0.72) and SEAP-NA (HPV16 ρ = 0.65, HPV18 ρ = 0.71) (all P < 0.001); correlation was lower with cLIA. The GST-L1 is suitable for evaluating HPV16/18 vaccine immunogenicity after 3 vaccine doses, although in contrast to other assays it may classify some samples as HPV16/18 seronegative. The assay's utility is limited for lower antibody levels such as after receipt of 1 dose.

Systematic review of the cost-effectiveness of the vaccination against HPV in Brazil.

In Brazil, almost 16,000 new cases of cervical cancer (CC), the type of neoplasia that claims the more lives of young women than any other, are expected in 2014. Although the vaccine against HPV has been developed, the application of this strategies to large populations is costly, and its use in Brazil is limited. Studies of the economic implications of new preventive technologies for CC may support rational and evidence-based decisions in public health. A systematic search of articles published between 2000 and 2014 was conducted using MEDLINE, EMBASE, the Cochrane Collaboration of Systematic Reviews, and LILACS. The aim of this search was the identification of original articles that evaluated the cost-effectiveness of vaccination against HPV in Brazil. A total of 6 articles are included in this review, evaluating the addition of a vaccine against HPV in comparison to population screening. Although the vaccine against HPV increases the cost of preventing cervical cancer, this new preventive technology presents favorable cost-effectiveness profiles in the case of Brazil. Failure to utilize the newly available preventative technologies against CC can lead to misguided and perverse consequences in a country in which programs based on the Papanicolaou test have been only partially successful.
