Cancer prevention programmes in Mexico: are we doing enough?

Cancer has increased in all the countries of the world and Mexico is no exception. The recognised risk factors for the main types of cancer are reviewed and searched through the Mexican government web pages and cancer prevention programmes to tackle the risk factors in the population. The Mexican government, a member of the World Health Organization, shows that the main approach is an early diagnosis rather than prevention, forgetting that an ounce of prevention is better than a pound of cure.

[Effect of a four-week vitamin and mineral supplementation on the nutritional status and urinary excretion of arsenic in adolescents].

Introduction: adequate nutrition in adolescence is important for growth and development. There are environmental factors that cannot be avoided, such as exposure to heavy metals through natural sources such as water. Arsenic is a metalloid that can cause damage to health (alterations in nutritional status, diabetes, cancer) and it has been found in concentrations higher than those allowed in drinking water.

Parameters of lung inflammation in asthmatic as compared to healthy children in a contaminated city.

Background: The impact of air pollution on the respiratory system has been estimated on the basis of respiratory symptoms and lung function. However; few studies have compared lung inflammation in healthy and asthmatics children exposed to high levels of air pollution. The aim of the study was to elucidate the modulatory effect of air pollution on Cysteinyl-leukotrienes (Cys-LTs) levels in exhaled breath condensate (EBC) among healthy and asthmatic children.

[Pre-anesthetic medication with intranasal dexmedetomidine and oral midazolam as an anxiolytic. A clinical trial].

Introduction: Dexmedetomidine is a pharmacological option for sedation in children. In this study, the efficacy of intranasal dexmedetomidine to reduce preoperative anxiety in pediatric patients is compared with that of oral midazolam.

Material And Methods: A prospective, randomized, double-blind, controlled trial was conducted on children 2-12 years of age, randomly assigned to one of the following two groups: group A received premedication with oral midazolam and intranasal placebo, group B received intranasal dexmedetomidine and oral placebo.

In vitro and in vivo biocompatibility of apatite-coated magnetite nanoparticles for cancer therapy.

The aim of this study was to determine the biocompatibility and potential toxicity of apatite-coated magnetite nanoparticles. The in vitro biocompatibility with human red blood cells was evaluated, not hemolytic effects were found at concentrations lower than 3 mg/ml. For the in vivo study, Balb/c mice were used.

Effect of glycine on lead mobilization, lead-induced oxidative stress, and hepatic toxicity in rats.

The effectiveness of glycine in treating experimental lead intoxication was examined in rats. Male Wistar rats were exposed to 3 g/L lead acetate in drinking water for 5 weeks and treated thereafter with glycine (100 and 500 mg/kg, orally) once daily for 5 days or glycine (1000 mg/kg, orally) once daily for 28 days. The effect of these treatments on parameters indicative of oxidative stress (glutathione and malondialdehyde levels), the activity of blood δ-aminolevulinic acid dehydratase, and lead concentration in blood, liver, kidney, brain, and bone were investigated.
