Seroprevalence and coprological prevalence of liver fluke Fasciola hepatica in cattle and sheep from Santander department, Colombia.

Fasciola hepatica is a parasite with a worldwide distribution that affects several mammals, including humans, and is considered a public health problem. Therefore, the aim of this study was to determine the prevalence of Fasciola hepatica in humans, cattle and sheep, as well as to evaluate factors associated with the prevalence. A total of 185 serum samples from sheep, 290 from cattle, and 114 from humans were collected and processed using an in-house developed ELISA to detect IgG antibodies against F.

The Characterization of Cardiac Explants Reveals Unique Fibrosis Patterns and a Predominance of CD8+ T Cell Subpopulations in Patients with Chronic Chagas Cardiomyopathy.

Aim: The present study aimed to characterize the histopathological findings and the phenotype of inflammatory cells in the myocardial tissue of patients with end-stage heart failure (ESHF) secondary to CCC in comparison with ESHF secondary to non-Chagas cardiomyopathies (NCC).

Methods: A total of 32 explanted hearts were collected from transplanted patients between 2014 and 2017. Of these, 21 were classified as CCC and 11 as other NCC.

[Clinical evolution of dengue in hospitalized patients].

Introduction: Dengue hemorrhagic fever has extended to every tropical and subtropical area of the world, resulting in a half million hospitalizations every year. This disease appears to affect increasing numbers of adolescents and young adults.

Objective: The clinical characteristics were described for adult and pediatric dengue inpatients to establish risk factors associated with bad prognosis.

[Clinical criteria to diagnose dengue in its early stages].

Introduction: Clinical differentiation of dengue from other diseases with similar symptoms is difficult. The case definition of the World Health Organization (WHO) has high sensitivity but its specificity is very low.

Objective: A diagnostic scale was formulated for early clinical diagnosis of dengue that provided greater accuracy than that of the WHO definition.

[Evaluation of the World Health Organization clinical definition of dengue].

Introduction: The distinction between dengue and other acute febrile diseases is difficult when based solely on symptoms.

Objective: An attempt was made to evaluate usefulness of dengue diagnoses in an endemic area (Bucaramanga, Colombia), based on the definitions recommended by the World Health Organization.

Materials And Methods: In a cohort >12 years of age with indications of acute febrile illness, the sensitivity, the specificity and the predictive values were determined based on the WHO dengue definition.
