Background & Aims: Prenatal folate exposure may alter epigenetic marks in the offspring. We aimed to evaluate associations between prenatal exposure to folic acid (FA) in preconception and in utero with cord blood DNA methylation in long interspersed nuclear element 1 (LINE-1) and Alu short interspersed nuclear elements (SINEs) as markers of global DNA methylation levels.
Methods: Data come from 325 mother-child pairs participating in the Nutrition in Early Life and Asthma (NELA) birth cohort (2015-2018).
Background: Cystic fibrosis (CF) has a vast and heterogeneous mutational spectrum in Europe. This variability has also been described in Spain, and there are numerous studies linking CFTR variants with the symptoms of the disease. Most of the studies analysed determinate clinical manifestations or specific sequence variants in patients from clinical units.

Design: Case-control study of 276 women between 20 and 35 years old from the Murcia region of Spain. Cases (n = 121) attended the Department of Gynaecology and Obstetrics of the University Clinical Hospital and were diagnosed with PCOS using Rotterdam criteria. Controls (n = 155) were women without PCOS attending the gynaecological outpatient clinic for routine gynaecological examinations.
