Effectiveness of enfuvirtide in a cohort of highly antiretroviral-experienced HIV-1-infected patients in Mexico.

Background: Treatments in patients with multidrug resistance often involve the use of multiple agents with partial antiviral activity and overlapping metabolic toxicities. Enfuvirtide is therefore a welcome addition to the antiretroviral management of patients with multiclass resistant virus, given the low risk of systemic toxicities and novel mechanism of action relative to existing drug classes. The aim of this study was to evaluate the effectiveness of ENF plus optimized background regimen (OBR) in a Mexican cohort of highly HIV-1 ARV-experienced patients.

Recreational physical activity is inversely associated with asymptomatic gallstones in adult Mexican women.

Background And Rationale: Epidemiologic research suggests that physical activity (PA) reduces the risk of chronic diseases including gallstones.

Objective: This study explores the association between recreational physical activity (RPA) and risk of asymptomatic gallstones (AG) in adult Mexican women.

Material And Methods: We performed a cross-sectional analysis of women from the Health Workers Cohort Study.

[Percutaneous closure of the patent ductus arteriosus in children with the Amplatzer Duct Occluder II].

Introduction: In the last decades, several devices have been used for the percutaneous closure of patent ductus arteriosus, with its own limitations and risks. The Amplatzer Duct Occluder II has been designed to overcome those limitations and reduce risks.

Objective: We described our initial series of patients who underwent percutaneous closure of patent ductus arteriosus with the Amplatzer Duct Occluder II, emphasis on the technical aspects of the procedure.

Protumor activities of the immune response: insights in the mechanisms of immunological shift, oncotraining, and oncopromotion.

Experimental and clinical studies indicate that cells of the innate and adaptive immune system have both anti- and pro-tumor activities. This dual role of the immune system has led to a conceptual shift in the role of the immune system's regulation of cancer, in which immune-tumor cell interactions are understood as a dynamic process that comprises at least five phases: immunosurveillance, immunoselection, immunoescape, oncotraining, and oncopromotion. The tumor microenvironment shifts immune cells to perform functions more in tune with the tumor needs (oncotraining); these functions are related to chronic inflammation and tissue remodeling activities.

[The pediatric patient at the end-of-life. A challenge for its identification and treatment. A survey in pediatricians and medical residents].

Background: Identification of pediatric patients at the end-of-life is not easy because criteria used are based on adults' criteria.

Objectives: In this survey we explore the children end-of-life definition pediatricians have, as well as to determine which interventions they use when caring a patient at end-of-life.

Setting: Tertiary referral pediatric hospital.

Activation of TLR2 and TLR4 by minimally modified low-density lipoprotein in human macrophages and monocytes triggers the inflammatory response.

Oxidized low-density lipoproteins and Toll-like receptors (TLR) 2 and 4 are involved in the development of atherosclerosis. The TLR are important in the pro-inflammatory response. The aim of this research was to analyze the activation of CD14, TLR4, and TLR2 in response to minimally modified low-density lipoprotein (mmLDL).

Transcatheter closure of patent ductus arteriosus using the amplatzer duct occluder in infants under one year of age.

Introduction And Objectives: Percutaneous closure of patent ductus arteriosus (PDA) is a well-established technique. We evaluated the usefulness of the Amplatzer duct occluder for the percutaneous closure of patent ductus arteriosus in 29 children under 1 year of age.

Methods: The patients' mean age was 8.

Periodicity and patterns of Entamoeba histolytica and E. dispar infection in HIV+/AIDS patients in Mexico.

In a 12-month longitudinal study, a cohort of Mexican HIV+/AIDS patients was checked several times for Entamoeba infection, with the parasites identified, as E. histolytica or E. dispar, using PCR.

Improvement in accuracy of gamma-glutamyl transferase for differential diagnosis of biliary atresia by correlation with age.

In order to determine the accuracy of serum gamma-glutamyl transferase (GGT) as a test for biliary atresia, we reviewed the charts of 29 infants with cholestatic jaundice less than one year of age. All patients underwent liver biopsy or laparotomy with cholangiogram to establish neonatal hepatitis (NH) or extrahepatic biliary atresia (EHBA). We also gathered information from 176 patients from published studies.

Effect of low-dose cyclosporine A in the treatment of refractory proteinuria in childhood-onset lupus nephritis.

We performed a prospective study to evaluate the efficacy and safety of low-dose cyclosporine A (CSA) treatment in paediatric lupus nephritis refractory to conventional therapy. Seven children with biopsy-proven Class III-IV lupus nephritis were treated with CSA (2-4 mg/kg/day) combined with low-dose prednisone for one year. All patients had failed to achieve sustained proteinuria remission with corticosteroids and cytotoxic drugs.

Epidemiology of cancer in children under one year of age in Mexico City.

In this work, the epidemiology of cancer in children under one year of age in Mexico City is described.
