    Abstract Visceral leishmaniasis (VL) requires diagnostic assays to complement clinical suspicion. However, there is no standardization of a diagnostic flow using available assays. This study aimed to evaluate the performance of parasitological, molecular, and serological assays for diagnosing VL and propose a diagnostic flow based on performance, practicality, and invasiveness. We conducted a study of 10-year (2010-2020) routine diagnoses of VL at the Brazilian National Reference Laboratory. We propose a diagnostic flow where individuals suspected of VL are initially screened for antibodies using an immunochromatographic test (ICT) with rK39 antigen on the nitrocellulose membrane. This is followed by a blood polymerase chain reaction (PCR) for Leishmania sp. kDNA and direct parasitological exam and/or PCR in bone marrow aspirate. A positive result in any of these assays can define a VL case. If clinical suspicion persists in negative individuals, the diagnostic flow should be repeated. The proposed flow has the potential to standardize and improve the diagnosis of VL. It reduces the need for invasive tests without compromising diagnostic accuracy.

    Abstract Background: Waste pickers are considered a vulnerable population at risk for potential health damage. Taking into account the risk of hepatitis B or C infection in this population, the aim of this study was to show the prevalence of these diseases in waste pickers from South America, through a systematic review.
    Methods: The search covered publications until February 2020, accessed through Google Scholar database. Epidemiological studies on hepatitis B or C focused on waste pickers in South America were included. All selected papers were evaluated for quality.
    Results: Six studies composed this systematic review, all conducted in Brazil and using cross-sectional study. The prevalence of all makers (HBsAg or anti-HBc) for hepatitis B varied from 4.3 to 33.4% while for hepatitis C varied from 1.6 to 12.4%.
    Conclusion: The lack of results showed the requirement for more research about hepatitis including this informal workers group. High prevalences of hepatitis B and C in waste pickers highlighted the need of increase preventive health protection as vaccination against hepatitis B; training on working conditions; and the use of individual protection.

    Abstract Wastes generated in healthcare facilities have been discussed and the World Health Organization has proposed a guideline for controlling the spread of the virus that causes Coronavirus Disease 2019 (COVID-19). However, waste management outside the generating facility should be discussed in more detail, taking into account factors such as virus resistance, differences in waste management systems and the climatic conditions in each affected region. Patients infected by human coronavirus being treated at home are generating infected waste possibly discarded as domestic waste, which can pose risks to workers and the environment, depending on the conditions of transport and disposal. In particular, the spread of the coronavirus may be increased by inadequate waste management, highlighting poor handling conditions associated with inappropriate use of personal protective equipment and other unfavourable conditions presented mainly in developing countries.

    Title translation Adequate solid waste management as a protection factor against dengue casesGestión adecuada de los residuos sólidos como factor de protección contra los casos de dengue.
    Abstract Objective: To investigate whether solid waste management and municipal socioeconomic indicators are associated with incidence rates of dengue, Zika, and Chikungunya in municipalities located in the state of Minas Gerais, Brazil.
    Methods: This exploratory, quantitative, cross-sectional study included all the 853 municipalities of Minas Gerais. Only secondary data were used, collected and grouped according to planning regions. Independent variables included regular urban solid waste collection, separated waste collection, and urban solid waste mass, in addition to a quality indicator of final waste disposal, municipal human development and Gini indices, monthly
    Results: Solid waste management was not associated with incidence of Zika or Chikungunya. In turn, the incidence of dengue was associated with solid waste management and had a significant inverse association with percent population vulnerable to poverty. A direct association was also observed with Gini index, suggesting that the higher the incidence of dengue from 2007 to 2016, the higher the municipal Gini coefficient and thus social inequality. Selective waste collection was inversely and significantly correlated with dengue cases, suggesting that the lower the coverage by regular separated waste collection, the higher the number of dengue cases.
    Conclusions: Solid waste management may influence the occurrence of dengue cases, and therefore should be considered in the planning of public health actions.

    Abstract Surfactants are substances that when in aquatic environments can cause negative impacts. Hospital effluents carry numerous chemicals daily, including surfactants, used in sanitization and disinfection procedures. These chemicals are found in the effluents and reach water bodies due to a lack of proper removal in the wastewater treatment plants. The present study investigated data about wastewater monitored from healthcare facilities located in the city of Belo Horizonte, Brazil, focusing on anionic surfactants. The results showed 72 establishments monitoring this parameter, resulting in a median concentration of 1 mg L

    Abstract Background: Ocular toxoplasmosis is the leading cause of infectious posterior uveitis worldwide, accounting for 30-50% of all cases in immunocompetent patients. Conventional treatment is associated with adverse effects and does not prevent recurrence. Intravitreal drug administration can improve disease outcomes and reduce side effects. Herein, we conducted a systematic review and meta-analysis on the efficacy of intravitreal injections for treating ocular toxoplasmosis.
    Methods: The systematic search was conducted using PubMed, SciELO, and Google Scholar with the descriptors "ocular toxoplasmosis" AND "intravitreal". We analyzed studies that met the inclusion criteria, i.e., experimental cases in patients treated intravitreally for ocular toxoplasmosis. Considering the systematic review, we focused on the number of intravitreal injections, the therapeutic drug class, and the presence of preexisting conditions. To assess the efficacy of intravitreal injections, a meta-analysis was performed using visual acuity, side effects, disease recurrence, and inflammatory responses as variables.
    Results: Intravitreal injection-induced side effects were rarely observed (0.49% [0.00, 1.51%] ). The use of antiparasitic and anti-inflammatory drugs afforded improved visual acuity (99.81% [98.60, 100.00%]) and marked effectiveness in treating ocular toxoplasmosis.
    Conclusions: Intravitreal injections may facilitate the successful treatment of ocular toxoplasmosis. However, clinicians should carefully evaluate the presence of preexisting conditions for ocular toxoplasmosis or previous diseases, as these can impact the decision to administer intravitreal injections.

    Abstract 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.

    Abstract Tenofovir disoproxil fumarate (TDF) is a drug used in HIV treatment, and several studies have detected its presence in surface water. Furthermore, more information on its environmental impact is needed in the scientific literature. Thus, due to the lack of data on the impact of this drug, and its presence in different waters of the world, this work aimed to evaluate the potential toxicological effects of TDF on the mollusk Biomphalaria glabrata in vivo and in vitro. For in vitro analysis, hemocytes were exposed to different drug concentrations for 1 h and evaluated for feasibility, and phagocytic and metabolic activity. The in vivo analysis consisted of the exposure of groups of five mollusks, in triplicate, at the same drug concentrations for 72 h and 21 days, evaluating mortality, and mollusk and hemolymph behavior. Although the exposure of the mollusk to TDF did not reduce its survival, however it was toxic to its hemocytes. Even if toxicity was identified on the mollusk and its hemocytes initially, further studies should be conducted to understand the effects of this residue on the environment and different life stages of the mollusk because, per the Globally Harmonized System of Classification and Labeling of Chemicals, for aquatic ecosystems, the results obtained were classified as toxic (EC50% 2.65 [1.98; 5.29] mg/L) and could cause unfeasibility in hemocytes at concentrations below 10 mg/l.
