Factors Associated with the Effectiveness of Regimens for the Treatment of Tuberculosis in Patients Coinfected with HIV/AIDS: Cohort 2015 to 2019.

(1) Background: Infection with the Human Immunodeficiency Virus (HIV) is a significant challenge for tuberculosis (TB) control, with increasing mortality rates worldwide. Moreover, the loss to follow-up is very high, with low adherence to treatment, resulting in unfavorable endpoints. This study aimed to analyze the effectiveness of TB treatment in patients coinfected with HIV/AIDS and its associated factors. (2) Methods: Patients coinfected with TB and HIV/AIDS at a Reference Hospital for infectious diseases were followed up for a maximum of one year from the start of TB treatment until cure or censorship (death, abandonment, and transfer) from 2015 to 2019. The Cox proportional model was used to identify risk factors for effectiveness. (3) Results: Of the 244 patients included in the cohort, 58.2% (142/244) had no treatment effectiveness, 12.3% (30/244) died, and 11.1% (27/244) abandoned treatment. Viral suppression at the onset of TB treatment (HR = 1.961, CI = 1.123-3.422), previous use of Antiretroviral Therapy (HR = 1.676, CI = 1.060-2.651), new cases (HR = 2.407, CI = 1.197-3.501), not using illicit drugs (HR = 1.763, CI = 1.141-2.723), and using the basic TB regimen (HR = 1.864, CI = 1.084-3.205) were significant variables per the multivariate Cox regression analysis. (4) Conclusion: TB treatment for most TB patients coinfected with HIV/AIDS was not effective. This study identified that an undetectable viral load at the beginning of the disease, previous use of ART, not using illicit drugs and not having previously taken anti-TB treatment are factors associated with successful TB treatment.

Evidence of cross-contamination of waste workers and transmission of antimicrobial resistance genes by coagulase-negative Staphylococcus isolated from dental solid waste: an intriguing study.

The aim of this study was to phenotypically and genotypically identify coagulase-negative Staphylococcus (CoNS) recovered from the nostrils of waste workers and from dental waste; 135 strains were recovered and S. epidermidis was the prevailing species. Genetic similarity (100%) was observed between the two S. epidermidis isolated from different employees on the same shift and 85% similarity between the S. epidermidis recovered from an employee's nostril and from waste. The mecA gene was found in 20 CoNS, and 20% were also found to possess the vanA gene. The blaZ gene was detected in 46.7%, and the icaA (34.8%), B and C genes (11.8% each). Our findings emphasized the biological risk to which waste workers are exposed and unprecedently confirms that it was possible to recover genetically identical bacterial species from waste and from workers' nostrils. It is important to highlight that this risk is raised by the detection of relevant antimicrobial resistance genes. The results also suggest that effective measures to correctly manage waste and promote the rational use of antimicrobials should be adopted.

The impact of the stratification by degree of clinical severity and abandonment risk of tuberculosis 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.

Assessment of factors associated with potential drug-drug interactions in patients with tuberculosis and HIV/AIDS.

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.

Prevalence of Campylobacter spp. in Chicken Carcasses in Slaughterhouses from South of Brazil.

Campylobacteriosis has become common cause of diarrhea in humans and is associated with Guillain-Barré 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.

Spatial association between sporotrichosis in cats and in human during a Brazilian epidemics.

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.

Factors associated with tuberculosis and multidrug-resistant tuberculosis in patients treated at a tertiary referral hospital in the state of Minas Gerais, Brazil.

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.

Drug therapy problems for patients with tuberculosis and HIV/AIDS at a reference hospital.

OBJECTIVE: To determine the frequency of drug therapy problem in the treatment of patients with tuberculosis and HIV/AIDS. METHODS: Data were obtained through a cross-sectional study conducted between September 2015 and December 2016 at a reference hospital in infectious diseases in Belo Horizonte (MG), Brazil. Sociodemographic, clinical, behavioral and pharmacotherapeutic variables were evaluated through a semi-structured questionnaire. Drug-related problems of pharmaceutical care were classified using the Pharmacotherapy Workup method. Factors associated with indication, effectiveness, safety and compliance drug therapy problem were assessed through multiple logistic regression. RESULTS: We evaluated 81 patients, and 80% presented at least one drug therapy problem, with indication and adherence drug therapy problem being the most frequent. The factors associated with drug therapy problem were age, marital status, new case, ethnicity, time of HIV diagnosis and time to treat tuberculosis. CONCLUSION: The frequency of drug therapy problem in coinfected patients was high and the identification of the main drug therapy problem and associated factors may lead the multiprofessional health team to ensure the use of the most indicated, effective, safe and convenient medicines for the patients clinical condition. Tuberculosis and HIV/AIDS coinfected individuals aged over 40 years are more likely to have drug therapy problems during treatment; in that, the most frequente are those that signal toward need of medication for an untreated health condition and non-compliance to treatment. Thus, older patients, unmarried or married, who have treated tuberculosis before, with a shorter time to tuberculosis treatment and longer time to diagnose HIV/AIDS, should receive special attention and be better followed by a multiprofessional health team because they indicate a higher chance of presenting Problems related to the use of non-adherent drugs.

RESUMO Objetivo: Determinar a frequência de problemas relacionados ao uso de medicamentos no tratamento de pacientes com tuberculose e HIV/AIDS. Métodos: Os dados foram obtidos por estudo transversal realizado entre setembro de 2015 e dezembro de 2016 em hospital referência em doenças infectocontagiosas de Belo Horizonte (MG), Brasil. As variáveis sociodemográficas, clínicas, comportamentais e farmacoterapêuticas foram avaliadas por questionário semiestruturado. Classificaram-se os problemas relacionados ao uso de medicamento empregando o método Pharmacotherapy Workup de atenção farmacêutica. Os fatores associados aos problemas relacionados ao uso de medicamentos de indicação, efetividade, segurança e adesão foram avaliados pela regressão logística múltipla. Resultados: Foram avaliados 81 pacientes, e 80% apresentaram pelo menos um problema relacionado ao uso de medicamentos, sendo os mais frequentes ligados à problemas relacionados ao uso de medicamentos de indicação e adesão. Os fatores associados aos problemas relacionados ao uso de medicamentos foram idade, estado civil, caso novo, etnia, tempo de diagnóstico do HIV e tempo de tratamento da tuberculose. Conclusão: A frequência de problemas relacionados ao uso de medicamentos em pacientes coinfectados foi alta, e a identificação dos principais problemas relacionados ao uso de medicamentos e dos fatores associados aos mesmos pode direcionar a equipe multiprofissional de saúde, para garantir o uso dos medicamentos mais indicados, efetivos, seguros e convenientes para a condição clínica dos pacientes. Os indivíduos coinfectados com tuberculose e HIV/AIDS maiores de 40 anos possuem maior chance de apresentarem problemas relacionados ao uso de medicamentos durante o tratamento, sendo os mais frequentes os que indicam a necessidade de medicamento para condição de saúde não tratada e não adesão ao tratamento. Pacientes mais idosos, solteiros ou não, que já trataram a tuberculose antes, com menor tempo de tratamento de tuberculose e maior tempo de diagnóstico de HIV/AIDS devem ter atenção especial no acompanhamento por uma equipe multiprofissional de saúde por indicarem maior chance de apresentar Problemas Relacionados ao uso de Medicamentos de não adesão à terapia.

Health-related quality of life of patients of Brazilian primary health care.

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.

Blood and milk polymorphonuclear leukocyte and monocyte/macrophage functions in naturally caprine arthritis encephalitis virus infection in dairy goats.

The exact influence of caprine arthritis encephalitis virus (CAEV) infection on blood and milk polymorphonuclear leukocytes (PMNLs) and monocyte/macrophages of goats remains unclear. Thus, the present study sought to explore the blood and milk PMNL and monocyte/macrophage functions in naturally CAEV-infected goats. The present study used 18 healthy Saanen goats that were segregated according to sera test outcomes into serologically CAEV negative (n=8; 14 halves) and positive (n=10; 14 halves) groups. All milk samples from mammary halves with milk bacteriologically positive outcomes, somatic cell count ≥2×106cellsmL-1, and abnormal secretions in the strip cup test were excluded. We evaluated the percentage of blood and milk PMNLs and monocyte/macrophages, the viability of PMNLs and monocyte/macrophages, the levels of intracellular reactive oxygen species (ROS) and the nonopsonized phagocytosis of Staphylococcus aureus and Escherichia coli by flow cytometry. In the present study, a higher percentage of milk macrophages (CD14+) and milk polymorphonuclear leukocytes undergoing late apoptosis or necrosis (Annexin-V+/Propidium iodide+) was observed in CAEV-infected goats; we did not find any further alterations in blood and milk PMNL and monocyte/macrophage functions. Thus, regarding our results, the goats naturally infected with CAEV did not reveal pronounced dysfunctions in blood and milk polymorphonuclear leukocytes and monocytes/macrophages.

Prevalence and risk factors associated with anti-Neospora caninum antibodies in dairy herds in the central region of Minas Gerais State, Brazil.

Neospora caninum is one of the parasites that frequently causes reproductive loses in cattle herds all over the world. Surveys have shown a high prevalence of the parasite in herds; in certain locations, 90% to 100% of dairy holdings are positives according serological tests. The aim of this study was to estimate the prevalence and risk factors associated with the increased number of seropositive dairy cattle in the central region of Minas Gerais, the largest milk producer state in Brazil. Samples were collected from 151 dairy herds and from 2915 lactating cows, and were evaluated by an indirect ELISA assay. According to results, animal prevalence was 21.9% (CI 95%: 18.9 to 24.9%), while the herd prevalence it was 98.5% (CI 95%: 97.0 to 99.9%). Poisson regression estimate the herd risk factors associated with the increased number of cases. An increased number of positive animals was related to the previous history of abortion and the presence of dogs. The use of individual natural colostrum feeding and reproductive techniques such as embryo transfer and in vitro fertilization are associated with a reduced number of seropositive animals in the herd. In conclusion, Neospora caninum is overspread across the dairy herds of the region, and it may be causing major economic losses for dairy farmers. The use of reproduction techniques, the access of dogs to the herds and the management of calf colostrum are important issues to be considered in the control of the disease.

Health-related quality of life of patients of Brazilian primary health care / Qualidade de vida relacionada à saúde dos usuários da atenção primária no Brasil

ABSTRACT 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.

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.

Serological profile, seroprevalence and risk factors related to Lawsonia intracellularis infection in swine herds from Minas Gerais State, Brazil.

BACKGROUND: Lawsonia intracellularis is the etiologic agent of proliferative enteropathy, which causes diarrhea in several animal species, including swine. Serology can be used both to determine the prevalence of antibodies against a specific pathogen in a herd and to obtain the serological profile, which is used to determine the dynamics of infection in the herd. The objective of this study was to determine the serological profile and seroprevalence of anti-L. intracellularis antibodies in swine herds from intensive production regions of Minas Gerais, Brazil, and to identify the risk factors related to the herd-level seropositivity. RESULTS: A total of 2999 serum samples were collected for this cross-sectional study in the four major regions of intensive swine production in Minas Gerais, Brazil. To obtain better estimates and increase the external validity of the seroprevalence, the sample data were weighted based on the pig population of each herd, the stratum in which the herd was classified and the swine population of the region where each herd was located. A questionnaire was used to identify potential risk factors related to this herd-level seropositivity. The overall weighted prevalence in Minas Gerais was 34.7% (95% confidence interval: 32.12 - 37.20%), and there was no significant difference among the sampled regions, with the seroprevalence rates ranging between 32.06 and 37.66%. Finishing pigs were the most prevalent among the sampled categories. Among the evaluated risk factors, "cleaning before disinfecting" had a negative impact in the seroprevalence (p < 0.05) and was considered a protective factor. CONCLUSIONS: The anti-L. intracellularis antibodies were detected in all of the investigated herds in Minas Gerais, which indicated a wide distribution of the agent in the state. The predominant serological profile was consistent with the dynamics of infection previously observed in pig herds in other countries with similar antimicrobial usage, in which the nursery pigs usually show the lowest seroprevalence and the finishing pigs exhibit the highest. Herds that adopt the practice of "cleaning before disinfection" can decrease their L. intracellularis antibody seropositivity.

Estimating the abortion risk difference in Neospora caninum seropositive dairy cattle in Brazil / Estimativa da diferença do risco de aborto em vacas leiteiras soropositivas para Neospora caninum no Brasil

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
