Headache disorders are the most common disorders of the nervous system. The lifetime prevalence of headache disorders show that some individuals never experience headache. The etiology of complete freedom from headache is not known. To assess genetic variants associated with complete freedom from headache, we performed a genome-wide association study of individuals who have never experienced a headache. We included 63,992 individuals (2,998 individuals with complete freedom from headache and 60,994 controls) from the Danish Blood Donor Study Genomic Cohort. Participants were included in two rounds, from 2015 to 2018 and in 2020. We discovered a genome-wide significant association, with the lead variant rs7904615[G] in ADARB2 (EAF = 27%, OR = 1.20 [1.13-1.27], p = 3.92 × 10). The genomic locus was replicated in a non-overlapping cohort of 13,032 individuals (539 individuals with complete freedom from headache and 12,493 controls) from the Danish Blood Donor Study Genomic Cohort (p < 0.05, two-sided). Participants for the replication were included from 2015 to 2020. In conclusion, we show that complete freedom from headache has a genetic component, and we suggest that ADARB2 is involved in complete freedom from headache. The genomic locus was specific for complete freedom from headache and was not associated with any primary headache disorders.

Background: In patients with atrial fibrillation (AF) undergoing coronary artery bypass grafting (CABG) or aortic valve replacement (AVR), many surgeons are reluctant to open the left atrium for surgical ablation. However, especially in those with persistent AF, a box lesion isolating the entire posterior left atrial wall may be beneficial. Here, we describe our initial experience with a novel closed atrium bipolar radio-frequency left atrial box ablation technique.

Objective: Although outcomes of repair of complete atrioventricular septal defect (cAVSD) have improved in recent years, the burden of reoperation on the left atrioventricular valve (LAVV) remains high. We investigated predictors of LAVV reoperation on the intra-operative echocardiogram that may help guide surgical decision making.
Methods: All patients who underwent repair of cAVSD at the Royal Children's Hospital from 2010 to 2020 were included in the study.

Purpose: Diabetes has the most detrimental impact on the dietary freedom of people with type 2 diabetes (T2D), and it is important to facilitate dietary self-care behaviors in people with T2D without impairing quality of life (QOL). Autonomous motivation to perform dietary self-care behaviors could lessen their psychological burden and maintain their QOL. Therefore, the purpose of the study was to identify the relationship between autonomous motivation for dietary self-care behaviors and QOL in people with T2D by establishing a hypothetical model using competence and implementation levels of dietary self-care behaviors as mediating variables.

Background: The greatest advantage of robotic surgery is that it enables precise surgery through a magnified three-dimensional (3D) image effect, multi-degree-of-freedom forceps, and a stable surgical field. However, it has disadvantages such as lack of tactile sensation and the existence of blind spots and the possibility of organ damage is higher in comparison to open or laparoscopic surgery. To solve these two major problems, we developed BirdView™, a wide view camera system.

Objectives: To examine the effects of death education using a situational puzzle board game versus reflective writing on nursing students' death anxiety, self-esteem and sense of meaning in life.
Background: Pre-clinical nursing students often exhibit high death anxiety due to limited clinical experience, potentially compromising future palliative care quality. Game-based learning shows promise in nursing education, warranting investigation for death education.
