What is the influence of maternal weight gain in different gestational clinical conditions on the prole weight in pre-school age?

The aim of the current study was to assess the influence of maternal weight gain in different clinical gestational conditions on the child's weight at pre-school age. This was a longitudinal observational study of a prospective and controlled multiple cohort of 372 mother-child pairs with four causal groups of different adverse intrauterine environments (smoking, diabetic, hypertensive and intrauterine growth-restricted pregnant women) and a control group, in the period of, from 2011 to 2016 in three hospitals in Porto Alegre (Brazil). Sociodemographic, prenatal and perinatal data were analysed.

Defect-Rich CuZn Nanoparticles for Model Catalysis Produced by Femtosecond Laser Ablation.

Femtosecond laser ablation of CuZn targets in ethanol led to the formation of periodic surface nanostructures and crystalline CuZn alloy nanoparticles with defects, low-coordinated surface sites, and, controlled by the applied laser fluence, different sizes and elemental composition. The Cu/Zn ratio of the nanoparticles was determined by energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, and selected area electron diffraction. The CuZn nanoparticles were about 2-3 nm in size, and Cu-rich, varying between 70 and 95%.

Environmental exposure to metal(loid)s and hypertensive disorders of pregnancy: A systematic review.

Background: Environmental exposure to metal(loid)s has been associated with adverse effects on human health, but the systemic repercussion of these elements on the development of hypertensive disorders of pregnancy (HDP) is still poorly understood.

Objective: To summarize evidence published about the influence of environmental exposure to aluminum, arsenic, barium, cadmium, lead, strontium and mercury on the development of HDP.

Methods: We conducted a systematic literature review according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses.

Mother-infant bonding: The role of postpartum depression, violence, and bonding established with one's own mother during childhood.

Mother-infant bonding is influenced by several risk and protective factors, and the literature has investigated the relationships between these factors independently. This study aimed to verify the interrelationships of some of these factors and how they influence mother-infant bonding in Brazil. In this study, 361 mothers participated, and the outcome variable of mother-infant bonding was assessed using the Postpartum Bonding Questionnaire (PBQ).
