Objective To evaluate the clinical effectiveness of the routine first-trimester screening for preeclampsia (PE) after being implemented in six Catalan maternities. Methods Participants in the reference group were recruited prospectively between October 2015 and September 2017. Participants in the study group were recruited retrospectively between November 2018 and May 2019, after implementing the screening program. PE risk was assessed between 11 + 0 and 13 + 6 weeks of gestation using the Gaussian algorithm combining maternal characteristics, mean arterial blood pressure, uterine artery pulsatility index, and maternal serum pregnancy-associated plasma protein-A. Women with a risk >= 1/137 were prescribed daily salicylic acid (150 mg) until 36 weeks of gestation. Results Preterm PE occurred in 30 of 2641 participants (1.14%) in the reference group, as compared with 18 of 2848 participants (0.63%) in the study group (OR: 0.55; 95% CI, 0.31-0.99; P = 0.045). In the reference group, 37 participants (1.40%) were admitted to ICU, as compared with 23 participants (0.81%) in the study group (OR: 0.57; 95% CI, 0.34-0.96; P = 0.035). Conclusion The routine first-trimester PE screening can be implemented in a public healthcare setting, leading to a significant reduction in the incidence of preterm PE and of maternal ICU admission.

BACKGROUND Previous studies have reported an association between maternal zinc deficiency and increased risk of nonsyndromic cleft lip with or without cleft palate (NSCL/P) in offspring. A high prevalence of zinc deficiency and a high prevalence of NSCL/P have been reported in Ecuador. We postulated that mothers of infants with NSCL/P may have lower serum zinc levels than women from the general population. METHODS A case series study was conducted from November 2013 to July 2016. Thirty-five healthy mothers of infants with NSCL/P were selected during surgical missions conducted by Operacion Sonrisa Ecuador. A single blood sample along with pertinent medical history was collected during personal interviews after 3.6 months postpartum. The prevalence of plasma zinc concentration (PZn) deficiency among the participants was determined and analyzed along with the prevalence of PZn deficiency in Ecuadorian women of reproductive age from the general population. RESULTS The mean PZn was 11.47 µmol/dm3 . The prevalence of PZn deficiency among the participants was 31.4% (95% CI: 17.1-48.6) and differed significantly from the prevalence of zinc deficiency observed among women from the general population (G2 = 8.66; p

Zinc is an important mineral for biological and physiological processes. Zinc deficiency (ZD) is one of the most common micronutrient deficiencies worldwide and a crucial determinant of pregnancy outcomes and childhood development. Zinc levels and the zinc supplementation rate among lactating women have not been assessed neither in Ecuador nor in the Andean region. We conducted a pilot study including 64 mothers of infants between eight days to seven months old from a primary care center located in Conocoto, a peri-urban community of Quito, Ecuador. The mothers were interviewed and a fasting blood sample was taken to determine plasma zinc levels. The prevalence of ZD was calculated and compared with the prevalence of ZD among Ecuadorian non-pregnant non-lactating women, and the sample was analysed considering zinc supplementation during pregnancy. The prevalence of ZD among the participants was 81.3% (95% CI: 71.7–90.9), higher than the reported among non-pregnant non-lactating women (G2 = 18.2; p < 0.05). Zinc supplementation rate was 31.2%. No significant differences were found comparing the groups considering zinc supplementation. The insights obtained from this study encourage extending studies to document zinc levels and its interactions among breastfeeding women in areas with a high prevalence of ZD in order to determine the need of zinc supplementation.
