Parental occupational exposure to anticancer drugs and radiation: Risk of fetal loss and physical abnormalities in The Japan Environment and Children's Study.

Background: Many studies have indicated an association between maternal occupational exposure to hazardous agents, such as anticancer drugs and ionizing radiation, and an increased risk of adverse pregnancy outcomes, including stillbirths or miscarriages and physical abnormalities in offspring. However, the effects of recent advancements in protective measures to reduce these risks have not been clarified. Aim To investigate the current impact of parental occupational exposure to anticancer drugs and ionizing radiation on stillbirths or miscarriages as well as physical abnormalities under the circumstances of the developed safety protocols.

Infants' early recovery from sleep disturbance is associated with a lower risk of developmental delay in the Japan Environment and Children's Study.

To examine whether patterns, such as the timings of onset or recovery from sleep disturbance, are associated with later developmental problems, including autism spectrum disorder (ASD). Mothers participating in the Japan Environment and Children's Study with a child aged 3 years were included in the analyses. Children were assessed for short sleep and frequent awakenings at 1 month, 6 months, and 1 year of age.

Effectiveness of the Abdominal Thrust Maneuver for Airway Obstruction Removal: Analysis of Data from the National Emergency Medical Services Information System.

Background: Foreign body airway obstruction (FBAO) is a life-threatening emergency. Abdominal thrusts are recommended as first aid, but the success rate for this technique is unclear. Using information from a large database of emergency medical services (EMS) data in the United States, we evaluated the success rate of abdominal thrusts and identified patient characteristics that were associated with the success of the technique.

[Efficacy of Anamorelin for the Treatment of Cancer Cachexia and Factors Associated with Weight Gain].

Cancer cachexia causes anorexia and metabolic disorders, eventually leading to sarcopenia, which in turn contributes to the development of functional disabilities. Although anamorelin hydrochloride tablets are marketed to treat cancer cachexia, their efficacy varies significantly among patients. Here, we investigated the efficacy of anamorelin and the factors associated with weight gain.

Association of placental weight at birth with maternal whole blood concentration of heavy metals (cadmium, lead, mercury, selenium, and manganese): The Japan Environment and Children's Study (JECS).

Background: Lifelong health is dependent on prenatal growth and development, influenced by the placental intrauterine environment. Charged with dual functions--exchange of oxygen and nutrients as well as a barrier against toxins--the placenta itself is susceptible to environmental exposure to heavy metals.

Objective: To examine the use of placenta weight as a biomarker for heavy metal exposure using a large Japanese cohort of pregnant women.
