Association between prenatal mercury exposure and pediatric neurodevelopment: The Japan environment and children's study.

Mercury pollution, including from its use during gold mining and refining, remains an important problem worldwide. In particular, methylmercury, a microbial alteration of mercury released into the environment, is a major environmental neurotoxicant. Although there has been growing concern about the health hazards of exposure to low levels of mercury, the effects of prenatal mercury exposure on neurodevelopmental outcomes in children have remained controversial.

Association of phenol exposure during pregnancy and asthma development in children: The Japan Environment and Children's study.

Background: Alkylphenols can originate from numerous products containing alkylphenol ethoxylates, including cleaning products, household items, and cosmetics. Some phenols, such as nonylphenol, are known to be endocrine disruptors, and exposure to them is thought to have contributed to the recent increase in allergic diseases such as asthma. However, the impacts of prenatal phenol exposure on asthma development in children are still unclear.

Renal Failure Without Hemodialysis Is a Risk Factor for Postoperative Complications in Colorectal Cancer Surgery.

Background/aim: Surgical outcomes of colorectal cancer (CRC) in patients with renal failure (RF) remain to be clarified. The objective of this research was to investigate how RF impacts the surgical outcomes in patients with CRC.

Patients And Methods: A retrospective analysis was performed on clinical data from 633 patients who underwent colorectal resection for CRC between January 2017 and December 2021.

Sex steroid hormones and allergic diseases in children: a pilot birth cohort study in the Japan Environment and Children's Study cohort.

Background: Numerous studies suggest that sex steroids might play a role in sex disparity observed in allergic diseases in adults. However, whether sex hormones influence allergic diseases in children remains unclear. The aim of the present study was to examine the association of sex steroid hormones with allergic disease in Japanese children.

Relationship between the Mediterranean Diet Score in Pregnancy and the Incidence of Asthma at 4 Years of Age: The Japan Environment and Children's Study.

Several scoring methods for the Mediterranean diet, which is considered as a healthy diet, are available, but studies that have compared more than one of these scores are rare. In addition, the applicability of Mediterranean diet scoring has not been sufficiently examined outside of Mediterranean regions. We collected data on the Mediterranean diet during pregnancy and the incidence of type 1 allergies in offspring from the Japan Environment and Children's Study.
