Mixtures of serum concentrations of organochlorine pesticides and breastfeeding duration.

The relationship between breastfeeding duration and maternal mixtures of organochlorine pesticides (OCP) biological concentrations has not been documented. For that reason, our objective was to evaluate the association between lactation duration and mixtures of OCP serum concentrations and their principal metabolites, as well as to identify the primary contributors within these mixtures. Consequently, we conducted a secondary analysis of 878 women over 18 years old who had at least one living child and served as controls in a population-based study from 2007 to 2011 in Northern Mexico.

Association between exposure to organophosphate pesticides and cytokine levels in a population of flower workers in Mexico.

The ability of organophosphate pesticides to disturb immune function has been demonstrated by in vivo and in vitro studies, but evidence of such effects on humans remains scarce. To assess the association between organophosphate pesticides exposure and cytokine levels in Mexican flower workers, a cross-sectional study was carried out. A questionnaire was provided to 121 male flower workers, and urine and blood samples were collected.

Leveraging Generative AI Models in Urban Science.

Since the late 2000s, cities have emerged as the primary human habitat across the globe, and this trend is anticipated to continue strengthening in the coming decades. As we increasingly inhabit human-designed urban spaces, it becomes crucial to understanding better how these environments influence human behavior and how individuals perceive the city. In this chapter, we begin by examining the interplay between urban form and social behavior, highlighting key indicators of urban morphology, and presenting state-of-the-art methodologies for data collection.

Breast cancer immunophenotypes and serum organochlorine pesticides in Mexican women: Mixture exposure approach.

Epidemiological studies on associations between breast cancer (BC) and organochlorine pesticides (OCP) are inconclusive. The majority of studies have evaluated the effect of single compounds without considering multiple OCP exposures and immunophenotypes of BC. We aimed to evaluate the association between BC immunophenotypes and serum OCP mixtures, and identify the main contributors within mixtures.

Diabetes mellitus and serum organochlorine pesticides mixtures in Mexican women.

Background: Very recently, it has been reported that exposure to different mixtures of organochlorine pesticides (OCP) is associated with the development of diabetes mellitus (DM). In Mexico, DM is a public health problem that might be related to the historical intense use of OCP. We aimed to evaluate, the association between DM and serum concentrations of OCP mixtures, and identify the main contributors within them.
