Congenital heart defects in children born after assisted reproductive technology: a CoNARTaS study.

Background And Aims: Children born after assisted reproductive technology (ART) have worse perinatal outcomes compared with spontaneously conceived children. This study investigates whether children conceived after ART have a higher risk of congenital heart defects (CHDs) compared with children born after spontaneous conception (SC).

Methods: All 7 747 637 liveborn children in Denmark (1994-2014), Finland (1990-2014), Norway (1984-2015), and Sweden (1987-2015), where 171 735 children were conceived after ART, were included.

The risk of Type 1 diabetes in children born after ART: a Nordic cohort study from the CoNARTaS group.

Study Question: Do children born after ART have a higher risk of developing Type 1 diabetes (DM1) than children conceived without ART?

Summary Answer: The risk of DM1 was similar for children conceived with and without ART, and there were no clear differences in risk according to method of fertility treatment.

What Is Known Already: ART is associated with a higher risk of adverse perinatal outcomes, and the risk depends on the method of ART. The Developmental Origins of Health and Disease theory proposes that prenatal stress can provoke changes in endocrine processes which impact health later in life.

Assessment of the intrasinusidal volume before and after maxillary sinus augmentation using mri - a pilot study of eight patients.

Purpose: The purpose of this study was to evaluate the suitability, accuracy, and reliability of a non-invasive 3-Tesla magnetic resonance imaging technique (3 T-MRI) for the visualization of maxillary sinus grafts in comparison to conventional, X-ray-based, established standard imaging techniques.

Methods: A total of eight patients with alveolar bone atrophy who required surgical sinus floor augmentation in the course of dental implantation were included in this pilot study. Alongside pre-operative cone-beam computed tomography (CBCT), 3 T-MRI was performed before and 6 months after sinus floor augmentation.

Osseointegration of titanium implants after surface treatment with ultraviolet light or cold atmospheric plasma in vivo.

Purpose: To determine the histological effects of ultraviolet light and cold atmospheric plasma treatment on the osseointegration of titanium implants in vivo.

Materials And Methods: Six juvenile pigs were divided into three groups of two animals each. A total of 54 titanium implants were placed randomly in the pigs' calvarial bone (nine implants per pig).
