Evaluation of three recombinant proteins for the development of ELISA and immun...
Santos, Anna Raquel Ribeiro dos; Serufo, Ângela Vieira; Figueiredo, Maria Marta; Godoi, Lara Carvalho; Vitório, Jéssica Gardone; Marcelino, Andreza PainBACKGROUND Visceral Leishmaniasis (VL) is an infectious disease that is a significant cause of death among infants aged under 1 year and the elderly in Brazil. Serodiagnosis is a mainstay of VL elimination programs; however, it has significant limitations due to low accuracy. OBJECTIVE This study aimed to evaluate three recombinant Leishmania infantum proteins (rFc, rC9, and rA2) selected from previous proteomi...
Prevalence of schistosomiasis mansoni in indigenous Maxakali villages, Minas Ge...
Nacife, Maria Beatriz Pena e Silva Leite; Siqueira, Liliane Maria Vidal; Martins, Rafael; Vianna, Valeska Natiely; Barbosa, Keila FurbinoIntestinal parasitic infections are a common health problem among Amerindian populations and schistosomiasis represents one of the most prevalent diseases in Maxakali people. The Kato-Katz is the diagnostic method recommended by WHO for epidemiological studies; however, one of the technique’s limitations is the failure to detect parasites in individuals with low parasite load. The aim of this study was to estab...

Contributions of mean and shape of blood pressure distribution to worldwide tre...
Coelho, George Luiz Lins Machado; Ezzati, MajidBackground Change in the prevalence of raised blood pressure could be due to both shifts in the entire distribution of blood pressure (representing the combined effects of public health interventions and secular trends) and changes in its high-blood-pressure tail (representing successful clinical interventions to control blood pressure in the hypertensive population). Our aim was to quantify the contributions o...
Prevalence of intestinal parasites among children 13-and-under residents in the...
Siqueira, Gabriela Lanna de Carvalho; Bakolis, Ioannis; Marinho, Carolina Coimbra; Vieira, Edivá de Paula; Pena, João Luiz; Rodrigues, Laura CunhaIntroduction: This study reports the prevalence of intestinal parasite infections in Xakriabá indigenous children living in the southeastern region of Brazil. Methodology: Stool samples of 2973 children 13-and-under were analyzed. Associations between environment factors and parasites were evaluated by multivariate Poisson regression model. Results: The prevalence of protozoa was high (Entamoeba histolytica/dis...
Hypovitaminosis D is associated with visceral adiposity, high levels of low-den...
Batista, Aline Priscila; Ambrosim, Ticiana Vazzoler; Nascimento Neto, Raimundo Marques do; Pimenta, Fausto Aloísio PedrosaBackground: Studies suggest that there is a strong association between low vitamin D levels and cardiovascular disease (CVD) and its risk factors (RFs). Hypovitaminosis D (25(OH)D < 30 ng/mL or 75 nmol/L) is a recent public health problem that has reached different populations. The objective of the study was to investigate whether hypovitaminosis D is an additional mechanism to explain the disturbances in the l...
