Hepatitis E Virus Infection and Butchers: A Case-Control Seroprevalence Study.

Background: Very few case-control studies to assess the risk of hepatitis E virus (HEV) infection in meat workers have been published. Therefore, we sought to determine: 1) the association of HEV IgG seropositivity and the occupation of butcher; and 2) the sociodemographic, work, clinical and behavioral characteristics of butchers associated with HEV exposure.

Methods: We performed a case-control seroprevalence study of 101 butchers (mean age: 38.

Hepatitis E virus infection and waste pickers: A case-control seroprevalence study.

Whether waste pickers are a risk group for hepatitis E virus (HEV) infection is largely unknown. This study aimed to determine the association between HEV exposure and the occupation of waste pickers and the work characteristics of waste pickers. An age-and gender-matched case-control seroprevalence study of 86 waste pickers and 86 control subjects of the general population was performed.

A Quest for New Cancer Diagnosis, Prognosis and Prediction Biomarkers and Their Use in Biosensors Development.

Traditional techniques for cancer diagnosis, such as nuclear magnetic resonance, ultrasound and tissue analysis, require sophisticated devices and highly trained personnel, which are characterized by elevated operation costs. The use of biomarkers has emerged as an alternative for cancer diagnosis, prognosis and prediction because their measurement in tissues or fluids, such as blood, urine or saliva, is characterized by shorter processing times. However, the biomarkers used currently, and the techniques used for their measurement, including ELISA, western-blot, polymerase chain reaction (PCR) or immunohistochemistry, possess low sensitivity and specificity.

Low prevalence of anti-hepatitis E virus IgG antibodies in Tepehuanos in Mexico.

Introduction And Objective: The epidemiology of infection with hepatitis E virus (HEV) in Tepehuanos (a Mexican ethnic group living in rural areas) is largely unknown. This study aimed to determine the seroprevalence of and risk factors associated with HEV infection in Tepehuanos in Durango, Mexico, and to compare this seroprevalence with that in non-Tepehuanos.

Materials And Methods: Through a case-control seroprevalence study, we studied 146 Tepehuanos and 146 age- and gender-matched control subjects of the general population from rural settings.

Association between Toxoplasma gondii infection and thyroid dysfunction: a case-control seroprevalence study.

Background: The association between Toxoplasma gondii infection and thyroid disease has been poorly studied. Therefore, we sought to determine the association between T. gondii seropositivity and thyroid dysfunction.

exposure and epilepsy: A matched case-control study in a public hospital in northern Mexico.

Objectives: This study aimed to determine the association between infection with and epilepsy in patients attended to in a public hospital in the northern Mexican city of Durango.

Methods: We performed an age- and gender-matched case-control study of 99 patients suffering from epilepsy and 99 without epilepsy. Sera of participants were analyzed for anti- IgG and IgM antibodies using commercially available enzyme-linked immunoassays.

Infection and Headache: A Matched Case-Control Study in a Public Hospital in Durango City, Mexico.

Background: () can disseminate to brain in infected hosts. Little is known about the magnitude of the association between this infection and headache. Therefore, we sought to determine the association of seropositivity and headache in patients attending neurological consultations in a public hospital in Durango City, Mexico.

Seroprevalence of selected viral, bacterial and parasitic infections among inpatients of a public psychiatric hospital of Mexico.

We sought to determine the frequency of serological markers of selected infections in a population of psychiatric patients in Durango City, Mexico, and to determine whether there are any epidemiological characteristics of the subjects associated with the infections. One hundred and five inpatients of a public psychiatric hospital of Durango were examined for HBsAg, anti-HCV antibodies, anti-HIV antibodies, anti-Brucella antibodies, rapid plasma reagin and anti-Cysticercus antibodies by commercially available assays. Anti-Cysticercus antibodies were confirmed by Western blot and HBsAg by neutralization assay.
