Embryo freezing for IVF appears linked to blood pressure problems in pregnancy

A large cohort study drawn from the national IVF registry of France, which included almost 70,000 pregnancies delivered after 22 weeks gestation between 2013 and 2018, has found a higher risk of pre-eclampsia and hypertension in pregnancies derived from frozen-thawed embryos. This risk was found significantly greater in those treatments in which the uterus was prepared for implantation with hormone replacement therapies. The results confirm with real-life data what has been observed in sub-groups of patients in other studies.

Depression in youth, between the ages of 10 and 24 years, is both a leading cause of stress and a possible risk factor for future diseases and impairment. Now, a study confirms that depression in childhood or adolescence is associated with higher levels of adult anxiety and substance use disorders, worse health and social functioning, less financial and educational achievement, and increased criminality.
