Campylobacteriosis has become common cause of diarrhea in humans and is associated with Guillain-Barre Syndrome, Reactive Arthritis and Irritable Bowel Syndrome is caused mainly by contaminated food and water intake in which the majority occurs from manipulation, preparation and consumption of poultry meat. The aim of this study was to estimate the prevalence of Campylobacter in chicken carcasses from slaughterhouses located in the states of Parana, Santa Catarina and Rio Grande do Sul in the South of Brazil. The samples were analyzed for Campylobacter enumeration using the ISO method 10272-2 and the species C. jejuni and C. coli, important for public health, were identified through Maldi-TOF mass spectrometry. From July 2017 to July 2018, 816 samples were analyzed, indicating the prevalence of 35.84%, with higher occurrence of C. jejuni (78.47%). No difference in prevalence was observed in relation to the size of the slaughterhouses. However, significant differences were noted among the three states in the southern region of the country, with the lowest prevalence being observed in Parana. The results reinforce the need to advance in the implementation of strategies to control this pathogen in the country, in order to safeguard consumer's health and contribute for the maintenance of Brazil's position in the international poultry meat market.

Brucellosis is a relevant zoonotic disease for which the most important tool for control is vaccination of susceptible animals. Assessment of vaccine efficacy in natural hosts is based on prevention of abortion and Brucella infection in organs of immunized animals. A meta-analysis of experimental vaccination of Brucella spp. natural hosts was performed, including 45 PubMed and/or Scopus-indexed publications, representing 116 individual experiments. Difference of risk was calculated as an indicator of protection, and a temporal analysis (1980-2016) demonstrated that experimental vaccines tested on natural hosts provided levels of protection that were stable over the past decades. The meta-regression model developed in this study included different vaccine categories (attenuated, inactivated, mutant, subunit, and vectored) considering the difference of risk as the dependent variable. The subcutaneous route of vaccination provided better protection when compared to the intramuscular and oral routes of vaccination. Surprisingly, inactivated vaccines provided better protection than live naturally attenuated vaccine strains (spontaneous mutations) that were considered the reference, whereas subunit vaccines provided lower levels of protection. This is the first meta-analysis of Brucella vaccinology in the natural hosts. These results are useful for the development of new vaccination protocols for controlling animal brucellosis. RESUMO: Brucelose é uma doença zoonótica relevante, para a qual a vacinação de animais susceptíveis é a ferramenta mais importante de controle. Avaliação da eficácia vacinal em hospedeiros naturais é baseada na prevenção de aborto e da colonização de órgãos pela Brucella spp. em animais imunizados. Foi realizada meta-análise de estudos de vacinação experimental de Brucella spp. em hospedeiros naturais, incluindo 45 publicações indexadas pela PubMed e/ou Scopus, representando 116 experimentos individuais. Diferença de risco foi calculada como indicador de proteção e uma análise temporal (1980-2016) demonstrou que vacinas experimentais testadas em hospedeiros naturais promoveram níveis de proteção que foram estáveis ao longo das últimas décadas. O modelo de meta-regressão desenvolvido neste estudo incluiu diferentes categorias de vacinas (atenuada, inativada, mutante, subunidade e vetorial) considerando a diferença de risco como variável dependente. A via de vacinação subcutânea promoveu melhor proteção quando comparada às vias intramuscular e oral. Surpreendentemente, vacinas inativadas promoveram melhor proteção que vacinas vivas atenuadas (com mutações espontâneas) que foram consideradas como referência, enquanto vacinas de subunidades promoveram menor proteção. Este é o primeiro estudo de meta-análise da vacinologia de Brucella em hospedeiros naturais. Estes resultados são úteis para o desenvolvimento de novos protocolos vacinais para controle de brucelose animal.

This cross-sectional study evaluated epidemiological and nutritional aspects as well as the microbial groups isolated from head and neck cancer patients, in the presence of oral mucositis. Three samplings were performed at baseline (jugal mucosa), on the 20 th radiotherapy session and on the last day of treatment, over oral mucositis lesions, if present. The sample was composed of 22 patients, mostly men (81.8%) and with a median age of 58.1(±12.7) years, 95% of them had concomitant smoking and drinking habits and 40.9% were edentulous. Body mass index values decreased during treatment and were statistically significant over time. During the study, there was a decline in Gram-positive cocci and an increase in Gram-negative rods. The recovery of yeast species increased along the study period. Isolation of multidrug-resistant microorganisms (44.3%) and those related to nosocomial infections (50.0%) was observed. Our findings suggested that there was a reduction in the indigenous oral microbiota and an increase in opportunistic species. The understanding of the microbial content of oral mucositis lesions as well as the clinical and nutritional aspects of head and neck cancer patients may contribute to a better oriented treatment.

Objective: Evaluate the impact of the instrument of the “Stratification by Degree of Clinical Severity and Abandonment Risk of Tuberculosis Treatment” (SRTB) on the tuberculosis outcome. Methods: This study was a pragmatic clinical trial involving patients with a confirmed diagnosis of tuberculosis treated at one of the 152 primary health care units in the city of Belo Horizonte, Brazil, between May of 2016 and April of 2017. Cluster areas for tuberculosis were identified, and the units and their respective patients were divided into intervention (use of SRTB) and nonintervention groups. Results: The total sample comprised 432 participants, 223 and 209 of whom being allocated to the nonintervention and intervention groups, respectively. The risk of treatment abandonment in the nonintervention group was significantly higher than was that in the intervention group (OR = 15.010; p < 0.001), regardless of the number of risk factors identified. Kaplan-Meier curves showed a hazard ratio of 0.0753 (p < 0.001). Conclusions: The SRTB instrument was effective in reducing abandonment of tuberculosis treatment, regardless of the number of risk factors for that. This instrument is rapid and easy to use, and can be adapted to different realities. Its application showed characteristics predisposing to a non-adherence to the treatment and established bases to mitigate its impact.

O risco de abandono do tratamento no grupo não intervenção foi significativamente maior do que no grupo intervenção (OR = 15,010; p < 0,001), independentemente do número de fatores de risco identificados. As curvas de Kaplan-Meier mostraram uma razão de risco de 0,0753 (p < 0,001). Conclusões: O instrumento ERTB foi eficaz em reduzir o abandono do tratamento da tuberculose, independentemente do número de fatores de risco identificados. Esse instrumento é rápido e fácil de utilizar e pode ser adaptado a diferentes realidades.

INTRODUCTION: The concomitant use of antituberculosis and antiretroviral drugs, as well as drugs to treat other diseases, can cause drug-drug interactions. This study aimed to describe potential drug-drug interactions (pDDI) in patients with TB and HIV/AIDS co-infection, as well as to analyze possible associated factors. METHODS: This study was performed in a reference hospital for infectious and contagious diseases in the southeastern region of Brazil and evaluated adult patients co-infected with tuberculosis and HIV/AIDS. A cross-sectional study was conducted in which sociodemographic, clinical, and pharmacotherapeutic characteristics were assessed. The pDDI were identified using the Drug-Reax software. Association analysis was performed using either a chi-squared test or a Fisher’s exact test. Correlation analysis was performed using the Spearman’s coefficient. RESULTS: The study included 81 patients, of whom 77 (95.1%) were exposed to pDDI. The most frequent interactions were between antituberculosis and antiretroviral drugs, which can cause therapeutic ineffectiveness and major adverse reactions. A positive correlation was established between the number of associated diseases, the number of drugs used, and the number of pDDI. An association was identified between contraindicated and moderate pDDI with excessive polypharmacy and hospitalization. CONCLUSIONS: We found a high frequency of pDDI, especially among those hospitalized and those with excessive polypharmacy. These findings highlight the importance of pharmacists in the pharmacotherapeutic monitoring in these patients.

Objective: To evaluate the risk factors for the development of tuberculosis and multidrug-resistant tuberculosis (MDR-TB) in patients treated at a tertiary referral hospital. Methods: This was a cross-sectional study based on data obtained from patients treated at the Júlia Kubitschek Hospital, located in the city of Belo Horizonte, Brazil, between October of 2012 and October of 2014. We evaluated sociodemographic, behavioral, clinical, and radiological variables. The outcome considered to identify associations between tuberculosis and the explanatory variables was the treatment prescribed. To evaluate the associations between MDR-TB and the same explanatory variables, the change in MDR-TB treatment was considered. Results: The factors associated with tuberculosis were alcoholism, comorbidities, pulmonary cavitations, and a radiological pattern suggestive of tuberculosis. Cavitation and previous treatment for tuberculosis were associated with MDR-TB. Conclusions: Despite the significant progress made in the fight against tuberculosis, there is a need for coordinated actions that include social protection measures and patient support. RESUMO Objetivo: Avaliar os fatores de risco de pacientes atendidos em um hospital de referência terciária para o desenvolvimento de tuberculose e tuberculose multirresistente (TBMR). Métodos: Estudo transversal baseado em dados obtidos de pacientes atendidos no Hospital Júlia Kubitschek, na cidade de Belo Horizonte (MG), entre outubro de 2012 e outubro de 2014. As variáveis utilizadas foram agrupadas em características sociodemográficas, comportamentais, clínicas e radiológicas. O desfecho considerado para verificar associações entre tuberculose e variáveis explicativas foi o tratamento prescrito para tuberculose. Para avaliar a associação entre a tuberculose resistente e as mesmas variáveis explicativas considerou-se a mudança de tratamento para TBMR. Resultados: Alcoolismo, padrão radiológico sugestivo de tuberculose, presença de comorbidades e presença de cavitações pulmonares foram fatores associados à tuberculose. A TBMR foi associada a tratamento prévio para tuberculose e presença de cavitações. Conclusões: Apesar dos importantes progressos na luta contra a tuberculose, é necessário um conjunto de ações articuladas que incluam medidas de proteção social e suporte aos pacientes.

Background: Tuberculosis (TB) remains an important cause of morbidity, the leading cause of death in patients with human immunodeficiency virus (HIV) infection, and a challenge to global public health. This study aimed to analyze the predictors associated with mortality among individuals coinfected with TB/HIV at a reference center in southeastern Brazil. Method: This retrospective cohort study used the data obtained from clinical records and information systems from 2007 to 2014. The data were analyzed using Cox proportional hazards model to identify the independent predictors. Results: Among the 924 individuals studied, 72.7 % were men. The median age was 38 years (range: 16–78 years). The mortality rate was 21.6%. The predictors associated with mortality were as follows: age over 50 years (Adjusted Hazard Ratio [AHR] : 2.52, 95% confidence interval [CI]: 1.39–4.59), CD4+ T lymphocyte count ≤200 cells/mm3 [AHR]: 1.40, 95% [CI]: 0.86–2.27), detectable viral load [AHR]: 1.73, 95% [CI]: 0.98–3.01), and non-use of antiretroviral therapy [AHR]: 2.91, 95% [CI]: 1.71–4.93). Conclusion: Results demonstrated that patients coinfected with TB/HIV have high mortality rates. Therefore, it is necessary to address the social determinants of health to provide every individual an equal opportunity to gain access to healthcare to cope with TB/HIV coinfection. Key words: Tuberculosis/HIV, Mortality, Retrospective cohort, Brazil.

This study examined neutrophil and monocyte functions and the blood lymphocyte profile of naturally BLV-infected cows with or without persistent lymphocytosis (PL). The percentage of neutrophils and monocytes that phagocytosed Staphylococcus aureus was lower in BLV-infected dairy cows, particularly those with PL. The relative percentage of CD44+ monocytes and neutrophils and CD11b expression by neutrophils was also lower in BLV-infected dairy cows with PL. A correlation between the percentage of CD11b+ neutrophils and that produced reactive oxygen species (ROS) was found. Furthermore, the percentage of CD44+ monocytes was positively correlated with the percentage of monocytes that phagocytosed S. aureus and the same phenomenon was observed for neutrophils. In BLV-infected dairy cows, particularly those with PL, inhibition of monocyte and neutrophil apoptosis was observed. Additionally, the percentage of neutrophils producing ROS was lower in BLV-infected cows with PL, in contrast to higher intensity of intracellular production of ROS by monocytes. The result from the lymphocyte immunophenotyping of BLV-infected cows with PL was an increase in B cells, mainly B CD5+ CD11b+, due to the apoptosis inhibition. In conclusion, this study provides novel insight into the implications of BLV infection for cattle, which can include the dysfunction of blood monocytes and neutrophils.

As a zoonotic disease, it poses a risk to human health, especially for veterinarians and breeders who handle materials potentially contaminated with Brucella canis. However, canine brucellosis is a neglected and underestimated disease given the difficulties in establishing a definitive diagnosis. We evaluated the frequency of detection of B. canis in 5 breeding kennels by using various serologic methods and PCR. Circulation of B. canis in these kennels was confirmed by bacterial isolation. The frequency of positive serologic results varied from 6.3% by AGID to 16.5% by dot-ELISA. There was no positive serology for smooth Brucella. PCR testing was positive in 13.9% of samples. The only detection tests with reasonable agreement were PCR and 2ME-MAT. The diagnosis of canine brucellosis remains challenging. The use of a single laboratory method, or even the use of different laboratory methods, may not be sufficient to reach a definitive diagnosis.

RESUMO Na representação da pecuária municipal do Brasil, o uso de indicadores com valoração absoluta ou relativa pode gerar subestimação ou superestimação da produção. O tipo de dado utilizado pode ser influenciado por fatores quantitativos produtivos associados ao tamanho das áreas e não ao maior desenvolvimento da atividade. O presente estudo comparou três tipos de dados para a representação do perfil produtivo da pecuária leiteira: o percentual produtivo, a densidade produtiva e a eficiência quantitativa. Os municípios que lideraram a produção no percentual produtivo foram os de maior tamanho (52.460ha em pastagem) com alto número de vacas pouco produtivas; opostamente, na densidade produtiva, foram agrupados os de menor tamanho (8.084ha em pastagem) com poucas vacas de alta produção. A melhor representação foi para a eficiência quantitativa que agrupou municípios de tamanho intermediário (23.234ha em pastagem) com alto número de vacas de alta produção. A eficiência quantitativa constitui uma nova abordagem na representação da pecuária leiteira, sua aplicação integra os critérios quantidade e eficiência e reduz os problemas gerados pela alta variação no tamanho das áreas municipais. ABSTRACT In the municipality's livestock product representation in Brazil, the use of indicators with absolute or relative valuation can generate problems such as underestimation or overestimation. The type of data used can be influenced by the quantitative productive factors associated to the area's size and not to the further development of the activity. The present study compared three types of data for the representation of the productive profile of the dairy livestock in Brazil: the productive percentage, the productive density, and quantitative efficiency. The municipalities that led the production in the productive percentage were larger (52,460 ha in pasture), with a high number of low production cows; on the other hand, the productive density grouped the smaller (8,084 ha in pasture) with few high production cows. The best representation was for the quantitative efficiency that grouped municipalities of intermediate size (23,234 ha in pasture) with a high number of cows with high production. The quantitative efficiency constitutes a new approach for the representation of dairy farming, its application integrates the criteria quantity and efficiency, and reduces problems caused by the high variation in the size of the municipal areas.

Sporotrichosis is a subcutaneous granulomatous disease caused by the fungus Sporothrix spp. In Brazil, S. brasiliensis is reported in regions of outbreaks and epidemics in the zoonotic form of the disease where cats play an important role in the transmission of the disease to humans. Therefore, it is important to assess how the presence of infected cats impacts the risk for sporotrichosis in humans. The objective of this study was to analyze the spatial association of sporotrichosis in cats and in humans from Belo Horizonte, a Brazilian city where an epidemics of sporotrichosis occurs since the first human case register in 2015, through an inhomogeneous Poisson process model. Feline and human cases of sporotrichosis recorded between January 2016 and June 2019 were georeferenced by address and spatial point patterns were generated. Feline case intensity and human demographic density were calculated using a kernel smoothed estimate. The distance to the nearest feline case was also compute. Model parameters were estimated by Maximum Likelihood Estimate. The model validation was performed by the evaluation of partial residual, leverage and influence measure. There were 343 cases of cats and 135 human cases of sporotrichosis. The average incidence of human sporotrichosis in the period was 1.343 per 100 thousand inhabitants, which is relatively low in relation to the population, but higher than that observed in other regions in zoonotic outbreak of the disease. The southern region of the municipality has a higher intensity of feline cases. According to the fitted model, the risk for human sporotrichosis is greater when at distances very close to a feline case, with a virtually stable effect for distances greater than 1 km. Regarding the intensity of feline cases there is a gradual increase in risk as the intensity of cases increases. From the leverage analysis it was observed that the model was particularly sensitive to the occurrence of human cases in the south and east regions, places with extreme values ​​of covariates. Poisson point process model seems to be a reasonable approach in spatial epidemiology when multiple sources of infection are involved, and there is a low incidence of the disease as long as it is reasonable to assume independence between cases. Interventions for disease prevention and control in humans are suggested to encompass disease control in cats and the search for feline cases, focused on diagnosis and control, close to reported human cases.

This report describes the network of live cattle exports from Brazil using Microsoft Office Excel® files, Terraview®, Maporama®, Pajek® and Google Maps® softwares. The database contains estimates obtained from the Ministry of Agriculture, Livestock and Food Supply (MAPA) and underwent descriptive, spatial and flow network. The network of live cattle exports from Brazil was determined using data from 27,517 Animal Transit Certificates (ATC) and 579 Veterinary Certificate for International Trade. International departure points, municipalities and states of origin, destination countries, purpose of export and compliance with sanitary requirements for exports, cattle movement and the main transportation corridors were showed through flow network. The states that exported live cattle were Para, Rio Grande do Sul, Tocantins, Sao Paulo, Minas Gerais and Maranhao. Vila do Conde Port, located in Barcarena municipality in the state of Para, was the main international departure point of animals, which were intended mostly for immediate slaughter in the importing country. The internal cattle transportation corridors of the main counties and farms that provide animals for exports in 2009 were mapped.

Neosporosis in cattle herds is associated with large economic losses, with abortion being the only clinical sign perceptible to the producer. Losses are estimated at over one billion dollars worldwide. This study aimed to estimate the abortion risk difference in seropositive animals using specific data for dairy herds in Brazil. Differences in the risk of abortion between seropositive and seronegative animals were calculated through a meta-analysis of previous data from several Brazilian states, and an increase of 10.04% (0.091 to 0.118) in the specific risk was identified. This finding indicates that more than 474,000 abortions caused by neosporosis may be occurring only in dairy cattle herds in Brazil, causing a major economic loss in the milk production chain. The use of this specific measure for Brazilian herds opens the possibility of developing cost-benefit analysis for neosporosis in Brazil using data that are more reliable A neosporose está relacionada a grandes perdas econômicas em rebanhos bovinos, tendo o abortamento como único sinal clínico perceptível ao produtor, com prejuízos estimados em mais de um bilhão de dólares em todo o mundo. O presente trabalho teve como objetivo estimar a diferença no risco de aborto em animais soropositivos, especificamente com dados procedentes de rebanhos leiteiros do Brasil. A diferença do risco de aborto foi calculada através de uma meta-análise, com dados precedentes de vários estados brasileiros, tendo como resultado um aumento de 10,04% (0,091-0,118) no risco específico. Este resultado demonstra que podem estar ocorrendo mais de 474 mil abortamentos no Brasil, devido à neosporose, apenas em rebanhos bovinos leiteiros, causando grandes perdas econômicas para cadeia produtora de leite. A utilização dessa medida específica de rebanhos brasileiros abre a possibilidade de modelagem econômica do custo da doença no Brasil com dados mais fidedignos

An important question about intramammary infections that is still debated in the literature is the independence or interdependence of the quarters of dairy cows. The present study sought to explore milk neutrophil function and the milk lymphocyte profile of uninfected quarters from uninfected and infected (one infected quarter per cow) udders to evaluate interdependence of the quarters. Thus, 32 (8 cows) and 18 (6 cows) uninfected quarters from uninfected and infected udders were used, respectively. Using flow cytometry, we evaluated the percentage of milk neutrophils and their expression of adhesion molecules L-selectin (CD62L), β2-integrin (CD11b), and an endothelial-selectin ligand (CD44); levels of intracellular reactive oxygen species (ROS); phagocytosis of Staphylococcus aureus by milk neutrophils; and neutrophil viability. Furthermore, we assessed the percentage of B-cell (CD21(+)) and T-lymphocyte subsets (CD3(+)/CD4(+)/CD8(-), CD3(+)/CD8(+)/CD4(-), CD3(+)/CD4(+)/CD25(-), CD3(+)/CD4(+)/CD25(+), and CD3(+)/CD4(-)/CD25(-)) using flow cytometry with monoclonal antibodies. The infected quarter did not affect somatic cell count or the percentage of neutrophils in the neighboring uninfected quarters. Furthermore, the infected quarter did not influence neutrophil viability, intracellular reactive oxygen species production, or phagocytosis of S. aureus by milk neutrophils. Conversely, the expression of adhesion molecules CD11b, CD62L, and CD44 by milk neutrophils differed between uninfected quarters from infected versus uninfected udders. The lymphocyte subsets did not differ between groups, except for a higher percentage of B cells in uninfected quarters from infected udders than in those from uninfected udders. Thus, our study strongly supports the hypothesis of interdependence of quarters based on the influence of infection on both the percentage of B cells and the expression of adhesion molecules by milk neutrophils in the neighboring uninfected quarters.

O conhecimento da fauna mantida ilegal é ferramenta importante para a conservação dos animais silvestres, pois permite o aprimoramento da educação ambiental e das ações fiscalizadoras. Objetivou-se diagnosticar as espécies da fauna silvestre apreendidas ou entregues voluntariamente no CETAS-BH e analisar espacialmente sua distribuição. As espécies foram identificadas e classificadas de acordo com a chave taxonômica e o risco de extinção. Na análise descritiva espacial, foram identificadas as coordenadas geográficas dos municípios dos animais para a construção dos mapas de distribuição e de densidade de Kernel. No ano de 2011, foram recebidos 7.426 animais vivos, dos quais 91,5% eram aves, 7% répteis e 1,5% mamíferos. Verificou-se ampla variedade de espécies (166), correspondendo às aves a maioria (79,5%). As espécies mais recebidas foram Sicalis flaveola e Saltator similis. Do total de espécies recebidas, 15% estavam ameaçadas de extinção. A principal procedência foi apreensão (82,7%) e, delas, 79% foram realizadas pela Polícia Militar do Meio Ambiente. Os animais eram de 94 municípios de MG. A análise espacial identificou a Região Metropolitana de BH como o local de maior concentração de ocorrências. A partir dos resultados obtidos, espera-se o aprimoramento e a intensificação das ações de educação ambiental e de fiscalização para essas áreas específicas The wildlife rehabilitation center in Belo Horizonte (CETAS - BH) is one of the responsible for the receipt of wild animals in Minas Gerais (MG). The knowledge about the animals traffic is an important instrument for the wild species conservation as it allows the improvement of environmental education and the enforcement actions. The research aimed to diagnose the species of wildlife seized or voluntarily surrendered in CETAS-BH and analyze their spatial distribution. The species were identified and classified according to the taxonomic key and the risk of extinction. Descriptive spatial analysis identified the geographic coordinates of the cities where the animals were found to make maps showing their spatial distribution and the Kernel density. In 2011 were received 7426 live animals, 91.5 % of these birds, 7% reptiles and 1.5% mammals. It was found a range of species (166), most of them birds (79.5%). The most received species were Sicalis flaveola and Saltator similis. Fifteen percent of the species were endangered. The main category of receiving was the seizure (82.7%), and 79% of them were conducted by Environment Police. The animals were from 94 cities in the state of Minas Gerais. The spatial analysis identified the Belo Horizonte Metropolitan Region as the region with the highest concentration of occurrences. In this context, this study suggests the improvement and intensification of environmental education and supervision in those specific areas

To demonstrate the utility of oral fluid (OF) for indirect diagnostic detection of Lawsonia intracellularis (Li), 15 pig farms were studied. Serum and fecal samples were collected from 20 animals from five different age groups on each farm. OF samples were collected from animals in two pens of the same age groups. Serum and OF samples were analyzed in an immunoperoxidase in monolayer assay (IPMA) for the detection of anti-Li immunoglobulin G (IgG) and A (IgA). Compatible results were found between PCR and IgG in OF in four of the five ages evaluated. Simultaneous detection of IgG in serum and OF was mainly observed on farms showing clinical signs suggestive of porcine proliferative enteropathy (PPE). These findings demonstrate the potential usefulness of OF in detecting anti-Li antibodies as a diagnostic tool that can be used to monitor PPE in herds with clinical signs compatible with the disease.

Objetivo: analisar a qualidade de vida relacionada à saúde dos usuários da atenção primária em saúde do Sistema Único de Saúde e fatores a ela associados. Métodos: estudo transversal com dados da Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015. A coleta de dados foi por meio de questionário que incluiu o instrumento Euroqol 5 Dimensions. Foram entrevistados usuários das cinco regiões do Brasil. Regressão linear múltipla foi utilizada para analisar a qualidade de vida relacionada à saúde e fatores associados. Resultados: do total de 8.590 usuários, as dimensões com maior frequência foram dor/mal-estar (50,7%) e ansiedade/depressão (38,8%). Cerca de 10% dos usuários reportaram problemas extremos nessas dimensões. Os fatores significantemente associados à pior qualidade de vida foram: ser do sexo feminino; ter artrite, artrose ou reumatismo; acidente vascular encefálico; doenças do coração; depressão; relatar autopercepção de saúde ruim/muito ruim; usar bebida alcoólica uma vez ou mais por mês; fazer dietas para perder peso, evitar o consumo de sal e reduzir o consumo de gordura. Foi observada associação significante entre uma melhor qualidade de vida e: residir no Norte e Sudeste; praticar atividades físicas e nível educacional mais alto. Não foi observada associação com fatores relacionados aos serviços de saúde. Conclusões: a qualidade de vida relacionada à saúde dos usuários foi influenciada por fatores demográficos, socioeconômicos, relacionados às condições de saúde e ao estilo de vida, sendo útil para nortear ações específicas de promoção da saúde e cuidado integral à saúde dos usuários do Sistema Único de Saúde. Objective: to analyze the Health-Related Quality of Life (HRQoL) of patients of the primary health care of the Brazilian Unified Health System (SUS) and its associated factors. Methods: this is a cross-sectional study with data from the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015 (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines – Services, 2015). Data were collected with a questionnaire that included the EuroQol 5 Dimensions (EQ-5D) instrument. Patients from the five regions of Brazil were interviewed. Multiple linear regression was used to analyze their Health-Related Quality of Life and its associated factors. Results: of the total of 8,590 patients, the most frequent dimensions were pain/discomfort (50.7%) and anxiety/depression (38.8%). About 10% of the patients reported extreme problems in these dimensions. The following factors were significantly associated with a worse quality of life: being female; having arthritis, osteoarthritis, or rheumatism; cerebrovascular accident; heart disease; depression; health self-assessment as poor or very poor; drinking alcoholic beverages once or more per month; dieting to lose weight, avoiding salt consumption, and reducing fat intake. Significant association was observed between a better quality of life and: living in the North and Southeast regions of Brazil; practicing physical activities; and having a higher educational level. No association was observed with factors related to the health services. Conclusions: the Health-Related Quality of Life of patients was influenced by demographic and socioeconomic factors that were related to health conditions and lifestyle, being useful to guide specific actions for promoting health and the integral care to patients of the Brazilian Unified Health System.

Veterinary drug residues in bulk tank milk are important to all sectors of the dairy chain because they are one of the major factors which determine the safety of the final product. This study attempted to identify milk quality parameters that are associated with the occurrence of veterinary drug residues using multivariate principal component analysis (PCA). A total of 132 raw milk samples were collected from 45 dairy farms in the state of Minas Gerais - Brazil and analyzed for 42 analytes, including pyrethroids, macrocyclic lactones and antibacterials, using liquid chromatography coupled with mass spectrometry in tandem mode and gas chromatography with electron capture detection. Out of the 132 milk samples, 40 samples tested positive for at least one analyte (above the detection limit). The milk parameters associated with the antimicrobial residues by confirmatory tests were lactose and nonfat concentrations, as revealed by PCA. This analysis showed that fat and total solid concentrations, as well as the somatic cell and total bacteria counts were associated with macrocyclic lactone residues in bulk tank milk. A PCA assessing pyrethroid residues in bulk tank milk revealed that the lactose and nonfat solid concentrations and titratable acidity were inversely associated with these residues. Thus, the data analysis indicated that the veterinary drug residues were associated with certain milk quality parameters that can be used to target farms at higher risk of veterinary drug residue contamination for testing programs in combination with incentives, education and training programs to improve mammary health, milk hygiene and safety.
