AI Article Synopsis

  • * Out of 82,972 participants, various conditions such as type 1 and type 2 diabetes, gestational diabetes, and dyslipidemia were identified, noting changes in biomarkers like cholesterol levels and triglycerides in relation to body mass index during pregnancy.
  • * The findings highlight that metabolic biomarkers are influenced by the timing of blood sampling and existing metabolic diseases, suggesting future studies will explore how these factors affect the health and development of children born to these mothers.

Article Abstract

Aims/introduction: We aimed to evaluate the metabolic status of pregnant women by assessing metabolic biomarkers of participants in the Japan Environment and Children's Study, a nationwide, multicenter, pregnancy and birth cohort.

Materials And Methods: Pregnant women aged 14-50 years were studied in 15 centers across Japan. Clinical information was obtained using self-administered questionnaires. Blood samples were taken during the first two trimesters to measure metabolic biomarkers. Samples were divided into seven groups according to the weeks of pregnancy.

Results: Among 82,972 pregnant women, 43 had only type 1 diabetes, 78 had only type 2 diabetes, 2,315 had only gestational diabetes and 354 had only dyslipidemia. Glycated hemoglobin, total cholesterol, low-density lipoprotein cholesterol and triglyceride across all the percentiles increased as prepregnancy body mass index increased, whereas high-density lipoprotein cholesterol levels across all the percentiles decreased as body mass index increased. Glycated hemoglobin was high in participants with type 1 diabetes or type 2 diabetes only, but not in those with gestational diabetes or hyperlipidemia only. Participants with type 2 diabetes or dyslipidemia only had high triglyceride in the first trimester, which then decreased in the second trimester. Participants with type 2 diabetes only also showed low high-density lipoprotein cholesterol, whereas participants with dyslipidemia only showed high total cholesterol and low-density lipoprotein cholesterol throughout.

Conclusions: Metabolic biomarkers were affected by blood sample timing and underlying metabolic disease. The Japan Environment and Children's Study will clarify the influences of metabolic status during pregnancy on the health and development of the offspring in future studies.

Assessing the impact of e-cigarettes on human barrier systems: a systematic review.

Transl Res

January 2025

Occupational Medicine, Department of Clinical and Experimental Medicine, University of Catania, 95124 Catania, Italy. Electronic address:

The use of e-cigarettes has grown rapidly in recent years, raising concerns about their impact on human health, particularly on critical physiological barriers such as the blood-brain barrier (BBB), alveolar-capillary barrier, and vascular systems. This systematic review evaluates the current literature on the effects of e-cigarette exposure on these barrier systems. E-cigarettes, regardless of nicotine content, have been shown to induce oxidative stress, inflammation, and disruption of tight junction proteins, leading to impaired barrier function.

Sporadic early miscarriages occur primarily due to embryonic aneuploidy. There is no evidence showing that stress is a direct cause of miscarriage. Yet, despite this, a national US survey and a Japanese survey found that many people mistakenly attributed miscarriage to the mental state or behavior of the women.

Objective: To evaluate whether there is an association between maternal mental health, purchase of psychotropic drugs, socioeconomic status and major congenital anomalies in offspring.

Methods: A register-based cohort study of 6189 Finnish primiparous women who had a singleton delivery between 2009 and 2015. Data on pregnancy and delivery outcomes, psychiatric diagnosis, prescription drug purchases and offspring congenital anomalies were obtained from Finnish national registers.

Background: Cardiovascular (CV) disease is a leading cause of death in pregnant women globally, especially in low- and middle-income countries including Latin America (LATAM), where there is lack of data on how cardiologists are trained in cardio-obstetrics (CO) and the practice patterns in the care of pregnant patients.

Objectives: The authors aimed to identify CO competency and practice patterns among LATAM general cardiologists.

Methods: An anonymous cross-sectional Google-based electronic survey was sent via email to clinical cardiologists through local American College of Cardiology chapters and CV societies.

Background: Cardiovascular diseases are the primary cause of nonobstetric morbidity and mortality in pregnant women worldwide. Pakistan's high maternal and neonatal mortality rates underscore the need for effective screening protocols to detect cardiovascular diseases during pregnancy.

Objectives: The objective of this study was to assess the prevalence and factors associated with structural heart disease among pregnant women without active cardiorespiratory symptoms (no symptoms or symptoms attributed to pregnancy) attending routine antenatal appointments.
