There is scarce evidence on sociodemographic and lifestyle characteristics that may explain adherence to different dietary patterns (DPs) during pregnancy. Our aims were to identify dietary patterns in a sample of pregnant Mexican women and to describe their association with selected sociodemographic and lifestyle characteristics. This is a secondary cross-sectional analysis of 252 mothers of children that participated as controls in a hospital-based case-control study of childhood leukemia.

Background: A heterogeneous geographic distribution of childhood acute lymphoblastic leukemia (ALL) cases has been described, possibly, related to the presence of different environmental factors. The aim of the present study was to explore the geographical distribution of childhood ALL cases in Greater Mexico City (GMC).

Methods: A population-based case-control study was conducted.

Article Synopsis
  • Childhood cancer, especially acute leukemia, is the leading cause of disease-related deaths in children aged 5-14 in Mexico, highlighting the need for understanding dietary influences during pregnancy.
  • A hospital-based study compared dietary habits of mothers of 109 infants with acute leukemia to those of 152 healthy controls, showing that overall maternal dietary patterns can significantly impact infant health.
  • The findings indicate that a "Balanced & Vegetable-Rich" diet during pregnancy is associated with a lower risk of acute leukemia in infants, particularly for mothers of girls, emphasizing the role of maternal nutrition in disease prevention.

Introduction: Maternal dietary consumption during pregnancy has been inconclusively associated with acute leukemia (AL) in infants, probably because epidemiological evidence has emerged mainly from the analysis of one-by-one nutrient, which is not a real-life scenario. Our objective was to evaluate the association between AL in Mexican children under 2 years of age and their mothers' nutrients concomitant intake during pregnancy, as well as to explore whether there are differences between girls and boys.

Methods: We conducted a study of 110 cases of AL and 252 hospital-based controls in the Mexico City Metropolitan area from 2010 to 2019.

Article Synopsis
  • - The study aimed to explore the relationship between parental age at conception and the risk of childhood acute leukaemia (AL) among Mexican children, given the high incidence of the disease in that population.
  • - A multicenter case-control approach was used, comparing children diagnosed with AL to matched controls, and applying statistical analysis to investigate the impacts of maternal and paternal ages on this risk.
  • - The findings revealed minimal associations between parental ages and childhood AL, though a higher risk for acute myeloid leukaemia (AML) was noted when mothers were 20-24 years old, and some association for acute lymphoblastic leukaemia (ALL) with younger mothers and fathers.

In Mexico, due to the high rates of diabetes, overweight, and obesity, there has also been noted an increased newborn weight, which may be contributing to the elevated incidence rate of childhood acute leukemia (AL). We conducted a case-control study in public hospitals of Mexico City aimed to know whether a greater weight at birth is associated with a higher risk of developing leukemia. We included incident cases with acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) diagnosed between 2010 and 2015.

Background: Postsurgical complications in patients with esophageal atresia have remained unchanged during the last three decades. This study was aimed at investigating certain risk factors for small-sized esophageal anastomosis and to assess the probable relationship between esophageal length and body weight in rabbit.

Methods: Six groups of 10 adult rabbits were subjected to section or 1-cm segmental resection of thoracic esophagus followed by end-to-end anastomosis.
