RESUMO

Artemia is a brine shrimp genus adapted to extreme habitats like ranges salinity from 5-25 g/L and in temperatures from 9 to 35 °C. It is widely distributed and used as an environmental quality biomarker. Artemia franciscana and Artemia salina species are commonly used in ecotoxicological studies and genotoxicity assays due to their short life cycle, high fecundity rate, easy culture, and availability. Thus, considering the importance of these tests in ecotoxicological studies, the present study aimed to present Artemia genus as a biological model in genotoxicity research. To this end, we reviewed the literature, analyzing data published until July 2023 in the Web of Science, SCOPUS, Embase, and PubMed databases. After screening, we selected 34 studies in which the genotoxicity of Artemia for various substances. This review presents the variability of the experimental planning of assays and biomarkers in genotoxicity using Artemia genus as a biological model for ecotoxicological studies and show the possibility of monitoring biochemical alterations and genetic damage effects. Also highlight innovative technologies such as transcriptomic and metabolomic analysis, as well as studies over successive generations to identify changes in DNA and consequently in gene expression.

RESUMO

Individual satisfaction is associated with increased retention in HIV/AIDS care services and adherence to treatment. This study assessed factors associated with individual satisfaction at the initiation of antiretroviral therapy and compared the proportions of satisfaction at the initiation of antiretroviral therapy and after three months of follow-up. Face-to-face interviews were carried out among 398 individuals of three HIV/ AIDS healthcare services in Belo Horizonte, Brazil. Variables included sociodemographic and clinical characteristics, perception about healthcare services, and domains of quality of life. Individuals that rated the quality of healthcare services as good or very good were classified as satisfied. A logistic regression analysis of the association between independent variables and individual satisfaction was performed. The proportion of individual satisfaction with healthcare services was 95.5% at the initiation of antiretroviral therapy and 96.7% after three months and these changes were not statistically significant (p = 0.472). The physical domain of quality of life was found to be associated with satisfaction at the initiation of antiretroviral therapy (OR = 1.38; CI = 1.11-1.71; p = 0.003). Training and supervision of health professionals for addressing the needs of individuals with lower levels of physical domain of quality of life may improve satisfaction with HIV/ AIDS care.

RESUMO

OBJECTIVE: To measure the incidence of neuropsychiatric adverse drug reactions (ADRs) in individuals living with HIV who initiated antiretroviral therapy (ART) with first-line regimens containing dolutegravir (DTG) or efavirenz (EFV) and associated factors. METHODS: Prospective cohort study with individuals living with HIV who started ART with DTG or EFV associated with tenofovir disoproxil and lamivudine in Belo Horizonte, Brazil. Sociodemographic, clinical, and laboratory data were collected from September 2015 to October 2018 in three specialized HIV care services through interviews, clinical records, and computerized systems. We analysed the frequency of neuropsychiatric ADRs recorded in clinical records 12 months after starting antiretroviral use, and the associated factors were investigated using binary logistic regression. RESULTS: A total of 152 (35.1%) of the 433 individuals included had neuropsychiatric ADRs. The incidence density was 35.3/100 person-years. The subjects mainly had sleep disorders and disturbances (21.3%), neurological disorders (13.9%), headaches (8.1%), and anxiety disorders and symptoms (3.0%), more frequently in individuals using EFV. A lower likelihood of neuropsychiatric ADRs was associated with using a DTG-based antiretroviral regimen (OR = 0.24; 95% CI = 0.14-0.40) and anxiety or depression signs and symptoms at the onset of treatment (OR = 0.57; 95% CI = 0.37-0.89). CONCLUSION: The incidence of neuropsychiatric ADRs was high in individuals starting ART with a lower likelihood of using a DTG-based regimen. The DTG-based regimen had a better safety profile for neuropsychiatric ADRs than the EFV-based regimen.

RESUMO

Over time, a growing increase in human pollutants in the aquatic environment has been observed. The global presence of residues in water bodies reinforces the need to develop improved methods to detect them and evaluate their ecotoxicological effects in aquatic environments. Thus, this study aimed to present the main assays using Biomphalaria glabrata as a biological model for ecotoxicological studies. We performed a systematic literature review with data published up to June 2022 on the Web of Science, SCOPUS, Science Direct, PubMed, and SciELO databases. Thirty studies were selected for this review after screening. Biomphalaria glabrata has been studied as an ecotoxicological model for different substances through toxicity, embryotoxicity, cytotoxicity, genotoxicity, and bioaccumulation assays. Studies evaluating the impact of B. glabrata exposure to several substances have reported effects on their offspring, as well as toxicity and behavioral and reproductive effects. This review presents various assays using B. glabrata as a biological model for ecotoxicological studies. The use of a representative species of ecosystems from tropical regions is a necessary tool for tropical environmental monitoring. It was observed that the freshwater snail B. glabrata was effective for the evaluation of the ecotoxicity of several types of chemical substances, but further studies are needed to standardize the model.

RESUMO

A quantitative descriptive study based on Brazilian Active Pharmacovigilance of Dolutegravir (DTG) Project was performed to describe the adverse drug reactions (ADRs) to DTG reported and to evaluate the noncompleteness of data from DTG active pharmacovigilance in Brazil. ADRs and clinical and individual data were obtained from information from the Pharmacovigilance Questionnaire from April 2017 to August 2019. The reported ADRs were classified using the Medical Dictionary for Regulatory Activities (MedDRA). In the evaluated period, 249,066 individuals using DTG participated in the active pharmacovigilance of DTG, with 3472 (1.39%) reporting ADRs at least once. A total of 6312 ADRs were reported, of which 57.56% were persistent and 81.46% were not serious according to the individuals' reports. Most of the reported ADRs were gastrointestinal, neurological and psychiatric. ADRs related to neural tube defects and serious neuropsychiatric ADRs have been reported. Completion of more than half of the fields in the Pharmacovigilance Questionnaire was excellent. The frequency of ADR was low in relation to the number of people living with HIV (PLHIV) using DTG in Brazil, which suggests good tolerability and safety of DTG. The DTG active pharmacovigilance database in Brazil showed good data completeness.

RESUMO

Levels of adherence to antiretroviral therapy (ART) can affect the likelihood of viral suppression differentially among ART regimens. In this prospective cohort conducted in Belo Horizonte, Brazil, we included 354 individuals who initiated ART containing tenofovir disoproxil fumarate/lamivudine/efavirenz in fixed-dose combination (TDF/3TC/EFV) or tenofovir disoproxil fumarate/lamivudine associated with dolutegravir (TDF/3TC + DTG). Viral suppression (viral load <50 copies/mL) was evaluated within six months of follow-up at different adherence levels and by therapeutic regimen. Adherence was measured by the Proportion of Days Covered (PDC) and classified into low (≤84%), intermediate (85-89%) or high (≥90%). The association between viral suppression, adherence levels, and other explanatory variables was analyzed using chi-square and multivariable logistic regression. Viral suppression was achieved by 76.0% of individuals and was more frequent among those who achieved higher levels of adherence (high adherence: 79.3%, intermediate: 71.4% and low: 45.2%), those on TDF/3TC + DTG, and those who had viral load ≤100,000 copies/mL at the onset of treatment (p < 0.05). Moreover, individuals on TDF/3TC + DTG had an approximately 90% probability of achieving viral suppression at intermediate adherence levels. These results add new insights on the possibility of lower adherence levels for contemporary antiretroviral regimens currently used as first-line therapy worldwide.

RESUMO

We examined trends in the prevalence of post-exposure prophylaxis following sexual exposure (PEPSE) per million population (2011-2019) and the proportion of repeated PEPSE within 365 days of the first PEPSE dispensing (2011-2018) in Brazil. We also compared the prevalence of repeated PEPSE according to patient and health services characteristics in 2018. The prevalence of PEPSE increased 55.5% from 2011 to 2019. Repeated PEPSE increased 11.8%, reaching 8.4% among people with their first dispensing in 2018. The prevalence of repeated PEPSE was higher in cis men or trans women (versus cisgender women); homosexuals (versus heterosexuals); and people aged 25-29 years (versus other age groups). We also observed greater prevalence of repeated PEPSE in HIV services in populous cities or services with elevated caseloads. Our findings highlight the need for strategies to reduce repeated PEPSE and promote other HIV-prevention technologies, particularly among young adults, cisgender men, transgender women, and homosexuals.

RESUMEN: Examinamos las tendencias de la prevalencia de uso de la profilaxis posterior a la exposición sexual (PEPSE) por millón de población (2011­2019) y la proporción de PEPSE repetida dentro de los 365 días de la primera dispensación de PEPSE (2011­2018) en Brasil. También comparamos la prevalencia de PEPSE repetida según las características del paciente y de los servicios de salud en 2018. La prevalencia de PEPSE aumentó un 55,5% de 2011 a 2019. La PEPSE repetida aumentó un 11,8%, alcanzando el 8,4% entre las personas con su primera dispensación en 2018. La prevalencia de PEPSE repetida fue mayor en hombres cis o mujeres trans (versus mujeres cisgénero); homosexuales (versus heterosexuales); y personas de 25 a 29 años (versus otros grupos de edad). También observamos una mayor prevalencia de repetición en los servicios de VIH de las ciudades más pobladas o con un elevado número de clientes. Nuestros hallazgos ponen de manifiesto la necesidad de estrategias para reducir la repetición de la PEPSE y promover otras tecnologías de prevención del VIH entre los adultos jóvenes, especialmente los hombres, las trans y los homosexuales.

RESUMO

OBJECTIVE: To evaluate the prevalence and factors associated with HIV/syphilis co-infection in people initiating antiretroviral therapy in Belo Horizonte, capital of the state of Minas Gerais. METHODS: A sectional section of a prospective cohort study was carried out with people living with HIV, treatment-naive, initiating antiretroviral therapy, older than 16 years, and in follow-up treatment at specialized HIV/Aids care services in Belo Horizonte. Sociodemographic, behavioral, clinical, laboratory and pharmacological treatment-related data were obtained through interviews, medical records, and information systems for logistical control of antiretroviral medications and laboratory tests. The dependent variable was the first episode of active syphilis, recorded by the physician in clinical records, within 12 months after beginning of the antiretroviral therapy. Factors associated with HIV/syphilis co-infection were assessed using binary multiple logistic regression. RESULTS: Among the 459 individuals included, a prevalence of 19.5% (n = 90) of sexually transmitted infections (STI) was observed, with syphilis (n = 49) being the most frequent STI in these individuals. The prevalence of HIV/syphilis co-infection was 10.6% (n = 49), and the associated independent factors were alcohol use (OR = 2.30; 95%CI: 1.01-5.26), and having a diagnosis of other sexually transmitted infections (OR = 3.33; 95%CI: 1.24-8.95). CONCLUSIONS: There was a high prevalence of HIV/syphilis co-infection in people living with HIV initiating antiretroviral therapy in Belo Horizonte. HIV/syphilis co-infection was associated with behavioral and clinical factors, such as alcohol use and diagnosis of other sexually transmitted infections. Prior knowledge about the factors associated with this co-infection may support the decisions of health professionals engaged in the care to people living with HIV, with regard to timely diagnosis, guidance, follow-up and adequate treatment, both for syphilis and HIV.

RESUMO

Visceral leishmaniasis (VL) is a public health problem with a high prevalence and lethality in Brazil. This study aims to estimate the lethality and associated factors in individuals with VL and assess survival time, emphasizing VL/HIV coinfection. This retrospective study has 37,583 individuals notified and confirmed with VL in the Sistema de Informação de Agravos de Notificação (SINAN) between 2007 and 2018 (Brazil). Lethality was evaluated considering VL deaths, deaths from other causes (OC), and non-deaths. We performed a multinomial logistic regression, with non-death as the benchmark category. We conducted a survival analysis (Kaplan-Meier method), emphasizing VL/HIV coinfection. Most individuals were young, male, mixed race, low schooling level, and urban dwellers. The lethality rate was 10.2% (VL and OC deaths) and 7.8% (VL deaths). The prevalence of HIV infection was 8.81%. A higher likelihood of VL and OC deaths was observed in older age groups, females, and with a higher number of symptoms. A higher likelihood of OC deaths was identified in individuals with HIV. A lower likelihood of VL and OC deaths was observed for individuals on VL therapy. The mean survival time was longer for VL/HIV individuals, who had a lower survival rate than those with VL. The data point to the need for attention to the timely diagnosis of VL and HIV and adequate pharmacological treatment in this population.

RESUMO OBJETIVO Avaliar a prevalência e os fatores associados à coinfecção HIV/sífilis em pessoas no início da terapia antirretroviral no município de Belo Horizonte, Minas Gerais. MÉTODOS Foi realizado um corte seccional de um estudo de coorte prospectivo, com pessoas vivendo com HIV, sem tratamento prévio da infecção, em início da terapia antirretroviral, maiores de 16 anos e em acompanhamento em serviços de assistência especializada em HIV/aids de Belo Horizonte. Dados sociodemográficos, comportamentais, clínicos, laboratoriais e relacionados ao tratamento farmacológico foram obtidos por meio de entrevistas, coleta em prontuários clínicos e nos sistemas de informação de controle de medicamentos antirretrovirais e exames laboratoriais. A variável dependente foi o primeiro episódio de sífilis ativa, registrado pelo médico em prontuário clínico, em um período de 12 meses após início da terapia antirretroviral. Os fatores associados à coinfecção HIV/sífilis foram avaliados por meio de regressão logística binária múltipla. RESULTADOS Dentre os 459 indivíduos avaliados, observou-se uma prevalência de 19,5% (n = 90) de infecções sexualmente transmissíveis, sendo a sífilis (n = 49) a infecção sexualmente transmissível mais frequente nesses indivíduos. A prevalência da coinfecção HIV/sífilis foi de 10,6% (n = 49) e os fatores independentes associados foram o uso de álcool (OR = 2,30; IC95% 1,01-5,26) e ter diagnóstico de outras infecções sexualmente transmissíveis (OR = 3,33; IC95% 1,24-8,95). CONCLUSÕES Houve alta prevalência de coinfecção HIV/sífilis em pessoas vivendo com HIV em início de terapia antirretroviral em Belo Horizonte. A coinfecção HIV/sífilis foi associada a fatores comportamentais e clínicos, como uso de álcool e diagnóstico de outras infecções sexualmente transmissíveis. O conhecimento prévio sobre os fatores associados à essa coinfecção pode subsidiar as decisões dos profissionais de saúde inseridos no cuidado às pessoas vivendo com HIV, no que diz respeito ao diagnóstico oportuno, orientações, acompanhamento e tratamento adequado, tanto da sífilis quanto do HIV.
