Abstract Objective To explore the decisional process of people living with human immunodeficiency virus (HIV) currently enrolled in antiretroviral clinical trials. Method Cross-sectional retrospective study. Outcome variables were reasons to participate, perceived decisional role (Control Preference Scale), the Decisional Conflict Scale and the Decisional Regret Scale. Descriptive statistics were calculated, and associations among these variables and with sociodemographic and clinical characteristics were analyzed with non-parametric techniques. Results Main reasons to participate were gratitude towards Fundación Huesped (47%), the doctor's recommendation (32%), and perceived difficulty to access treatment in a public hospital (28%). Most patients thought that they made their decision alone (54.8%) or collaboratively with the physician (43%). Decisional conflict was low, with only some conflict in the support subscale (median=16.67). Education was the only significant correlate of the total decisional conflict score (higher in less educated patients; p=0.018), whereas education, recent diagnosis, living alone, lower age, being man and doctor's recommendation to go to Fundación Huésped related to higher conflict in different subscales. Nobody regretted to participate. Conclusions The decision making regarding participation in HIV trials, from the perspective of participants, was made respecting their autonomy and with very low decisional conflict. Currently, patients show no signs of regret. However, even in this favorable context, results highlight the necessity of enhancing the decision support in more vulnerable patients (e.g., less educated, recently diagnosed or with less social support), thus warranting equity in the quality of the decision making process.

Resumen Objetivo Explorar el proceso de decisión de las personas que viven con el virus de la inmunodeficiencia humana (VIH) y participan en ensayos clínicos de antirretrovirales. Método Estudio retrospectivo transversal. Las variables de resultado fueron los motivos para participar, el rol de participación percibido (Escala de preferencia de control), la Escala de conflicto decisional y la Escala de arrepentimiento decisional. Se realizó una estadística descriptiva y se establecieron asociaciones entre estas variables con variables sociodemográficas y clínicas usando técnicas no paramétricas. Resultados Las razones para participar fueron la gratitud hacia la Fundación Huésped (47%), la recomendación del médico (32%) y la dificultad percibida para acceder al tratamiento en un hospital público (28%). Los pacientes opinan que tomaron su decisión solos (54,8%) o en colaboración con el médico (43%). El conflicto en la decisión fue bajo, aunque hubo cierto conflicto en la subescala de apoyo (mediana=16,67). La educación se relacionó con el conflicto en la decisión (mayor en pacientes con menor nivel educativo; p=0.018), mientras que la educación, el diagnóstico reciente, vivir solo, la menor edad y la recomendación del médico de ir a la Fundación Huésped se relacionaron con un mayor conflicto en diferentes subescalas. Nadie se arrepintió de su participación. Conclusiones Desde la perspectiva de los participantes, en el proceso de toma de decisiones se respetó su autonomía, hubo poco conflicto decisional y no aparecen signos de arrepentimiento. A pesar de este contexto favorable, los resultados destacan la necesidad de mejorar el apoyo a las decisiones en las personas más vulnerables (con menos educación, de diagnóstico reciente o con menos apoyo social) para garantizar la equidad en la calidad del proceso de decisión.

Neutralization with alkaline compounds is one of the most common adulterations in milk. The rosolic acid method is a classical test widely used in different countries for detection of neutralizers in milk. The official and a modified version were validated in a single laboratory validation process considering four adulterants: sodium bicarbonate(BI), sodium carbonate(CA), sodium hydroxide(HY) and sodium citrate(CI). The modified version, which presented better performance was selected for interlaboratory validation. In this process, samples of raw milk with acidities of 0.19% were neutralized with different concentrations of BI, CA, HY and C and tested for homogeneity and stability. Eight laboratories, which represented different sectors of the milk production chain, received and analysed these samples. The collaborative trial results confirmed the method performance, although sensitivity and precision were inferior to those obtained in the intralaboratory process, demonstrating its applications and limitations.

Resumo Um paciente de 24 anos do sexo masculino, previamente hígido, apresentou-se com uma história de dois meses de dor epigástrica, náuseas, vômitos, fadiga e mal-estar. Ele relatava abuso de diferentes substâncias, incluindo um composto vitamínico veterinário injetável contendo altas doses de vitamina A, D e E, e um veículo oleoso que induz edema local com aumento de volume muscular. A creatinina sérica estava 3,1 mg/dL, alanina transaminase 160 mg/dL, aspartato transaminase 11 mg/dL, testosterona total 23 ng/dL, 25-OH-vitamina D > 150 ng/mL (toxicidade > 100), 1,25-OH-vitamina D 80 pg/mL, vitamina A 0,7 mg/dL, paratormônio < 3 pg/mL, cálcio total 13,6 mg/dL, cálcio urinário de 24h 635 mg/24h (VR 42-353). Uma ultrassonografia do trato urinário demonstrou sinais de nefropatia parenquimatosa. O diagnóstico foi hipercalcemia e insuficiência renal aguda secundária a intoxicação por vitamina D. Ele foi tratado inicialmente com hidratação intravenosa, furosemida e prednisona. No quinto dia de hospitalização uma dose de pamidronato dissódico foi adicionada. O paciente evoluiu com normalização do cálcio sérico e da função renal. Trinta dias depois ele apresentou testes clínicos e laboratoriais normais, exceto a 25-OH-vitamina D que estava persistentemente elevada (107 ng/mL), já que ela pode demorar vários meses para normalizar. Este relato de caso é um alerta aos riscos relacionados ao uso de substâncias veterinárias para fins estéticos.

Abstract A previously healthy 24 yo male presented with a two-month history of epigastric pain, nausea, vomiting, fatigue and malaise. He reported abuse of different substances, including an injectable veterinary vitamin compound, which contains high doses of vitamin A, D and E, and an oily vehicle that induces local edema and enhances muscle volume. Serum creatinine was 3.1 mg/dL, alanine transaminase 160 mg/dL, aspartate transaminase 11 mg/dL, total testosterone 23 ng/dL, 25-OH-vitamin D >150 ng/mL (toxicity >100), 1,25-OH-vitamin D 80 pg/mL, vitamin A 0.7 mg/dL, parathormone <3 pg/mL, total calcium 13.6 mg/dL, 24-hour urinary calcium 635 mg/24h (RV 42-353). A urinary tract ultrasound demonstrated signs of parenchymal nephropathy. The diagnosis was hypercalcemia and acute renal failure secondary to vitamin D intoxication. He was initially treated with intravenous hydration, furosemide and prednisone. On the fifth day of hospitalization a dose of pamidronate disodium was added. The patient evolved with serum calcium and renal function normalization. Thirty days later he presented normal clinical and laboratory tests, except 25-OH-vitamin D that was persistently increased (107 ng/mL), as it may take several months to normalize. This case report is a warning of the risks related to the use of veterinary substances for aesthetics purposes.

ABSTRACT Objective To determine rates of retention, antiretroviral therapy (ART) use, and viral suppression in an adult cohort from a public tertiary referral hospital in the city of Buenos Aires, Argentina. Methods HIV-positive ART-naïve patients ≥ 18 years old starting care 2011-2013 contributed data until the end of 2014. Three outcomes were assessed in 2014: retention in care, ART use, and viral suppression. Patient characteristics associated with each outcome were assessed through logistic regression. Results A total of 1 031 patients were included. By the end of 2014, 1.5% had died and 14.8% were transferred to a different center. Of the remaining 859 patients, 563 (65.5%) were retained in 2014. Among those retained, 459 (81.5%) were on ART in 2014. Of those 459 on ART, 270 (58.8%) were virologically suppressed. Younger age was associated with lower retention (OR (odds ratio): 0.67; 95% CI (confidence interval): 0.44-0.92 for ≥ 35 vs. < 35 years), but unrelated with ART use or viral suppression. Low CD4 count at first visit was associated with ART use (OR: 35.72 for CD4 < 200, 7.13 for CD4 200-499 vs. ≥ 500, P < 0.001) and with virologic suppression (OR: 2.17 for CD4 < 200, 2.46 for CD4 200-499 vs. ≥ 500, P: 0.023). Conclusions Our hospital in Buenos Aires is still below the recommended 90-90-90 targets of the Joint United Nations Programme on HIV/AIDS (UNAIDS) for ART use and viral suppression. We found a major gap in retention in care. Identifying younger age as being associated with worse retention will help in the design of targeted interventions.

RESUMEN Objetivo Determinar las tasas de retención, uso de tratamiento antirretroviral (TAR) y supresión viral en una cohorte adulta de un hospital público de referencia de atención terciaria en la ciudad de Buenos Aires (Argentina). Métodos Pacientes de 18 años de edad o mayores seropositivos al VIH que no habían recibido tratamiento con antirretrovirales y que comenzaron a ser atendidos entre el 2011 y el 2013 aportaron datos hasta finales del 2014. En el 2014 se evaluaron tres resultados: la retención de los pacientes en los servicios de atención, el uso de TAR y la supresión viral. Se usó la regresión logística para evaluar las características de los pacientes asociadas con cada resultado. Resultados Se estudió a 1 031 pacientes. A finales del 2014, 1,5% habían fallecido y 14,8% fueron transferidos a otro centro. De los 859 pacientes restantes, en el 2014 se retuvieron en los servicios a 563 (65,5%). Entre los que siguieron asistiendo a los servicios, 459 (81,5%) recibieron tratamiento antirretroviral ese año. De esos 459 que recibieron tratamiento antirretroviral, se alcanzó la supresión viral en 270 (58,8%). Se determinó que una menor edad estaba asociada a una menor tasa de retención (razón de posibilidades (OR): 0,67; intervalo de confianza de 95% (IC): 0,44-0,92 para ≥ 35 frente a < 35 años), pero no con el uso de tratamiento antirretroviral o la supresión viral. También se determinó que un bajo nivel de CD4 en la primera consulta estaba asociado al uso de tratamiento antirretroviral (OR: 35,72 para CD4 < 200, 7,13 para CD4 200-499 frente a ≥ 500, P < 0,001) y a la supresión viral (OR: 2,17 para CD4 < 200, 2,46 para CD4 200-499 frente a ≥ 500, P: 0,023). Conclusiones Nuestro hospital en Buenos Aires todavía está por debajo de las metas 90‑90‑90 recomendadas por el Programa Conjunto de las Naciones Unidas sobre el VIH/SIDA (ONUSIDA) para el uso de terapia antirretroviral y la supresión viral. Encontramos una brecha importante en la retención de los pacientes en los servicios de atención. La asociación de una menor edad con peores tasas de retención será útil en el diseño de intervenciones destinadas a poblaciones específicas.

AbstractObjective To determine the prevalence of adequate monitoring and the costs of measuring CD4+ T-lymphocytes (CD4+ cell) and human immunodeficiency virus (HIV) viral load in people receiving antiretroviral therapy (ART) in seven countries in the WHO Region of the Americas. Methods We obtained retrospective, longitudinal data for 14 476 adults who started a first ART regimen at seven HIV clinics in Argentina, Brazil, Chile, Haiti, Honduras, Mexico and Peru between 2000 and 2011. We estimated the proportion of 180-day periods with adequate monitoring, which we defined as at least one CD4+ cell count and one viral load measurement. Factors associated with adequate monitoring were analysed using regression methods. The costs of the tests were estimated.Findings The median follow-up time was 50.4 months; the proportion of 180-day periods with adequate CD4+ cell counts was 69% while the proportion with adequate monitoring was 62%. Adequate monitoring was more likely in participants who were older, who started ART more recently, whose first regimen included a non-nucleoside reverse transcriptase inhibitor or who had a CD4+ cell count less than 200 cells/µl at ART initiation. The cost of one CD4+ cell count ranged from 7.37 United States dollars (US$) in Argentina to US$ 64.09 in Chile; the cost of one viral load measurement ranged from US$ 20.34 in Brazil to US$ 186.28 in Haiti.Conclusion In HIV-infected participants receiving ART in the WHO Region of the Americas, CD4+ cell count and viral load monitoring was often carried out less frequently than regional guidelines recommend. The laboratory costs of monitoring varied greatly.

ResumenObjetivo: Determinar la prevalencia de un monitoreo adecuado y los costes de medición de los linfocitos T CD4+ (célula CD4+) y la carga viral del virus de inmunodeficiencia humana (VIH) en personas que reciben terapia antirretroviral (TAR) en siete países de la Región de las Américas de la OMS.Métodos: Se obtuvieron datos retrospectivos y longitudinales de 14.476 adultos que comenzaban un primer régimen de TAR en siete clínicas de VIH en Argentina, Brasil, Chile, Haití, Honduras, México y Perú entre 2000 y 2011. Se estimó la proporción de periodos de 180 días con un monitoreo adecuado, lo que se definió como al menos un recuento de células CD4+ y una medición de la carga viral. Se analizaron factores relacionados con un monitoreo adecuado mediante la utilización de métodos de regresión. Se estimaron los costes de las pruebas.Resultados: La mediana de tiempo de monitoreo fue de 50,4 meses; la proporción de periodos de 180 días con recuentos de células CD4+ adecuados fue del 69%, mientras que la proporción de un monitoreo adecuado fue del 62%. Un monitoreo adecuado era más propenso en participantes mayores, que habían comenzado el TAR más recientemente, cuyo primer régimen incluía un inhibidor de la transcriptasa inversa no nucleósido o que tenían un recuento de células CD4+ menor de 200 células/μl en el inicio del TAR. El coste de un recuento de células CD4+ comprendía desde los 7,37 dólares de los Estados Unidos (USD) en Argentina a los 64,09 USD en Chile; el coste de una medición de la carga viral comprendía desde los 20,34 USD en Brasil a los 186,28 USD en Haití.Conclusión: Entre los participantes infectados por el VIH que recibían el TAR en la Región, el recuento de células CD4+ y la medición de la carga viral eran a menudo realizadas con menor frecuencia que la recomendada por las directrices regionales. Los costes de laboratorio del monitoreo variaban considerablemente.

Estudo descritivo, transversal, correlacional, que objetivou verificar a associação entre a presença de ansiedade e depressão após a alta hospitalar em pacientes submetidos à intervenção coronária percutânea (ICP), segundo o sexo. Foram avaliados 59 pacientes submetidos à ICP e em acompanhamento ambulatorial nos primeiros sete meses após a alta hospitalar. Para avaliação de sintomas de ansiedade e de depressão foi utilizada a Escala Hospitalar de Ansiedade e Depressão (HADS). Para testar as possíveis associações entre as variáveis ansiedade, depressão e sexo foi utilizado o teste de qui-quadrado, com nível de significância de 5%. Os resultados indicaram maior número de mulheres com depressão, sendo que a associação entre as variáveis sexo e depressão mostrou-se estatisticamente significativa. Em relação à ansiedade, os casos foram mais frequentes no sexo masculino e a associação entre as variáveis sexo e ansiedade não foi estatisticamente significativa.

A descriptive, cross-sectional, correlational study aimed to investigate the association of sex and the presence of anxiety and depression after hospital discharge in patients who underwent percutaneous coronary intervention (PCI). Fifty-nine patients undergoing PCI and receiving outpatient treatment in the first seven months after hospital discharge were evaluated. To assess the symptoms of anxiety and depression the Hospital Anxiety and Depression Scale (HADS) was used. To test the possible associations between the variables anxiety, depression and sex the Chi-square test was used with a significance level of 5%. The results indicated a greater number of women with depression and the association between the variables sex and depression was statistically significant. In relation to anxiety, cases were more frequent in males and the association between the variables sex and anxiety was not statistically significant.

Existem diversos ingredientes que podem substituir aqueles que são comumente utilizados na produção das dietas animais com o intuito de reduzir os custos de produção, como o resíduo da filetagem de tilápia. No entanto, em se tratando de resíduos, estudos adicionais são necessários para avaliar os seus exatos efeitos sobre o produto final. Assim, um experimento foi desenvolvido para avaliar os efeitos da inclusão de cinco diferentes níveis (0%, 2%, 4%, 6% e 8%) de resíduo da filetagem de tilápia (Oreochromis niloticus) (FT) nas dietas de frangos de corte sobre o rendimento de carcaça e características sensoriais da carne. Foram utilizados 480 pintos de um dia, da linhagem Cobb, distribuídos num delineamento experimental inteiramente casualizado, com cinco tratamentos, seis repetições e 16 aves por unidade experimental. Ao final do período experimental (42 dias), os parâmetros de rendimento de carcaça, peito, coxa, sobrecoxa, asa, peso relativo do fígado e percentual de gordura abdominal foram mensurados. A análise sensorial da carne foi realizada por 45 provadores não treinados. As amostras foram avaliadas utilizando a escala hedônica estruturada, composta por nove pontos para as seguintes características: aroma, sabor, cor, textura e qualidade global. Considerando o período total (1 a 42 dias) pode-se incluir 8% de FT nas rações de frangos de corte, sem prejuízo para os parâmetros de rendimento e qualidade sensorial da carne.

There are several ingredients that can replace those commonly used in the manufacture of animal ration in order to reduce production costs, as tilapia by products meal. However, as byproducts, more studies should be done to achieve the exact effects over the final product. An experiment was carried out aiming at evaluate the effects of the inclusion of five different levels (0%, 2%, 4%, 6% and 8%) of tilapia (Oreochromis niloticus) byproducts meal (TM) on poultry diets on carcass yield and sensory characteristics of broiler chicken meat. 480 one day old chicks, Cobb strain, were used to set the experiment with five treatments arranged in completely randomized design, with six replicates, and 16 birds per experimental unit. At the end of the experiment (42 days), the carcass yield parameters, breasts, drumsticks, thighs, wings, relative weight of the liver, and percent of abdominal fat were evaluated. A sensorial test of the meat was performed by 45 non-trained testers. The samples were evaluated using a structured hedonic scale, comprising nine steps to characterize the following senses: aroma, flavor, color, texture and whole quality. The addition of 8% TM to the diet fed to broiler chickens during total rearing period (1 to 42 days) is feasible without altering yield and sensorial quality of the meat.

This study was carried out to evaluate the effect of supplementation of probiotics (Lactobacillus acidophilus, Enterococcus faecium and Bifidubacterium bifidum) and antibiotics (flavomicina and staquinol) on diets for broilers from 1 to 42 days of age, reared in clean (new litter) and challenged (reused litter) environments. A total of 768 one-day-old male broilers of the Cobb 500 strain were distributed in a completely randomized design in a 2 × 4 factorial arrangement (2 litter types × 4 diets), totaling eight treatments with eight replications and 16 poultry per experimental unit. The results of performance and carcass characteristics were submitted to analysis of variance using the Studen Newman Keuls test at 0.05 probability. In the period of 1-21 days of age, the supplementation with probiotics for poultry raised in the new litter reduced feed intake, whereas in those raised in reused litter, the diet free of growth promoter showed a lower consumption. Poultry from 1 to 42 days raised in new litter had lower feed intake when supplemented with probiotics. Other results of performance and carcass yield were not affected. For the poultry raised in reused litter, the use of probiotics resulted in lower thigh yield and higher liver yield. The use of different growth promoters in feed for broilers does not influence the performance of poultry raised in new or reused litter. The use of probiotic promotes lower feed intake without compromising the performance, regardless of the type of litter used, demonstrating the feasibility of using this product as substitute for antibiotics.

O objetivo deste estudo foi identificar os fatores individuais e ambientais associados ao uso de parques e praças por adultos de Curitiba-PR. Estudo transversal realizado em 2008, no qual 749 participantes (59,9% homens) foram intencionalmente selecionados em áreas destinadas para a prática de atividade física (AF) em quatro parques e quatro praças. A regressão de Poisson foi utilizada para verificar a associação entre variáveis sociodemográficas (sexo, idade, escolaridade), de saúde (índice de massa corporal, percepção de saúde), companhia para uso do parque/praça, acesso (percepção de distância, acesso e deslocamento até o local) e prática de AF de lazer (caminhada e AF moderada/vigorosa - AFMV) com a frequência habitual aos locais (>1 vez/sem). O uso de parques e praças foi de 68% e fatores como a companhia (RP: 0,74; IC95%: 0,62-0,89) e maiores níveis de caminhada (RP: 1,30; IC95%: 1,03-1,64) e AFMV (RP: 1,39; IC95%: 1,07-1,80) apresentaram associação com o uso dos locais. Estes resultados devem guiar intervenções para disponibilizar serviços e estruturas para a prática de AF em parques e praças.

The aim of this study was to identify individual and environmental factors associated with park and plaza use in adults from Curitiba, state of Paraná, Brazil. A cross-sectional study was conducted in 2008 with 749 participants (59.9% men) selected in areas for physical activity (PA) in four parks and four plazas. Poisson regression was used to examine the associations of sociodemographic (sex, age, education) and health (body mass index, perceived health) variables, company for park/plaza use, access (perception of distance, access and commuting to the places), and leisure time PA (walking and moderate/vigorous PA - MVPA) with frequent use of parks and plazas (>1 time/wk). The percentage of park and plaza use was 68%, and company (PR: 0.74; CI95%: 0.62-0.89) and higher levels of walking (PR: 1.30; CI95%: 1.03-1.64) and MVPA (PR: 1.39, CI95%: 1.07-1.80) were associated with the use of the places. These results can be used to guide interventions aimed at providing services and facilities for PA practice in parks and plazas.
