The increasing geographical spread and disease incidence of arboviral infections are among the greatest public health concerns in Americas. region has observed an trend dengue last decades, evolving from low to hyperendemicity. Yellow fever also intensified this period, expanding sylvatic-restricted activity urban outbreaks. Chikungunya started spreading pandemically 2005 at unprecedented pace, reaching Americas 2013. following year, Zika emerged with explosive outbreak, carrying devastating...
In a multicenter study, hepatitis A virus (HAV) seroprevalence was surveyed in six countries Latin America which 12,000 subjects were stratified for age. The highest rates of recorded the Dominican Republic (89.0%) and Mexico (81.0%), with lower Brazil (64.7%), Chile (58.1%), Venezuela (55.7%), Argentina (55.0%). HAV children between 1 5 years age less than 50%, except Republic. 5-10-year-old group, have also decreased compared previous reports. This suggests that epidemiology is shifting...
Abstract Background Malnutrition in children can be a consequence of unfavourable socioeconomic conditions. However, some families maintain adequate nutritional status their despite living poverty. The aim this study was to ascertain whether family-related factors are determinants stunting young Mexican extreme poverty, and these differ between rural or urban contexts. Methods A case-control conducted one poverty level areas Mexico. Cases comprised stunted aged 6 23 months. Controls were...
Seventy-six children < or =2 years old were prospectively followed for 1 year in a peri-urban community of Mexico City to determine asymptomatic infection and acute diarrhea associated with diarrheagenic Escherichia coli pathotypes (DEPs). By use pathogen-specific multiplex PCR, DEPs sought 795 stool samples, which 125 (16%) positive DEP; these, 4 represented shedding episodes parasite coinfections. Most single-DEP infections (85/117) (P 0.001), the 32 DEP episodes, 41% atypical...
Project control is a crucial phase within project management aimed at ensuring —in an integrated manner— that the objectives are met according to plan. Earned Value Management —along with its various refinements— most popular and widespread method for top-down control. For under uncertainty, Monte Carlo simulation statistical/machine learning models extend earned value framework by allowing analysis of deviations, expected times costs during progress. Recent advances in explainable machine...
A child with infant botulism became apneic and died while receiving ampicillin gentamicin therapy. As aminoglycosides have been implicated in the induction and/or exacerbation of neuromuscular blockade, we used an animal model to test hypothesis that potentiate blockade botulinum toxin. In range aminoglycoside doses utilized these experiments, both tobramycin enhance impairment death toxin-exposed mice. These results support recently published clinical observations may weakness caused by...
OBJECTIVE. Gastrointestinal parasites continue to be an important cause of morbidity and stunting among children in developing countries. We evaluated the effect vitamin A zinc supplementation on infections by Giardia lamblia, Ascaris lumbricoides, Entamoeba histolytica. METHODS. randomized, double-blind, placebo-controlled trial was conducted 707 who were 6 15 months age from periurban areas Mexico City, Mexico, between January 2000 May 2002. Children, assigned receive either every 2...
ABSTRACT The identification of immune response mechanisms that contribute to the control diarrheal disease in developing countries remains an important priority. We addressed role fecal chemokines and cytokines resolution Escherichia coli Giardia lamblia infections. Stools collected from 127 Mexican children 5 15 months age enrolled a randomized, double-blind, placebo-controlled, vitamin A supplementation trial were screened for enteropathogenic (EPEC), enterotoxigenic E. (ETEC), . Fecal...
The seroprevalence of hepatitis B was investigated in over 12 000 subjects six countries Latin America: Argentina, Brazil, Chile, the Dominican Republic, Mexico, and Venezuela. Each study population stratified according to age, gender, socioeconomic status. Antibodies against core antigen (anti-HBc) were measured order determine infection. highest overall found Republic (21.4%), followed by Brazil (7.9%), Venezuela (3.2%), Argentina (2.1%), Mexico (1.4%), Chile (0.6%). In all an increase...
ABSTRACT Sixty-three children in periurban Mexico City were examined for the occurrence of asymptomatic norovirus (NoV) infection from June to August 1998. NoV was detected 48 161 stool specimens (29.8%), with 31 (49.2%) having at least one positive stool. Asymptomatic occurred commonly during summertime a Mexican pediatric population.

Using an indirect immunofluorescence assay on stool samples, we found a 6.4% prevalence of cryptosporidiosis among 403 children less than five years age with acute diarrhea in Mexico City over one-year period. The was highest (11.4%) during the rainy summer months. Most Cryptosporidium parvum cases occurred infants one year age. more common malnourished (P < 0.05) and nonbreast-fed six months 0.01). Neither dwelling characteristics nor presence domestic animals at home were associated C....
