Right and Left Coronary and Conus Arteries Originating from Three Separate Ostia in the Right Valsalva Sinus in a Japanese Cadaver: A Case Study with Literature Review.

A rare case of an anomalous location of the orifice of the coronary artery was found in a 99-year-old male cadaver undergoing routine dissection. The presence of the right coronary artery (RCA), left coronary artery (LCA), and conus artery (conus branch) originating from the right Valsalva sinus are the characteristic findings of this case. Then, the LCA passed through the aorta and the pulmonary artery.

Comparative analysis of dental trauma in contact and non-contact sports: A systematic review.

Dental traumas in sports are common and have physical, social, psychological, and economic impacts. The aim of this study was to determine, through a systematic review, the prevalence of dental trauma in contact and non-contact sports. This review was submitted to PROSPERO (CRD42023421206).

Challenges to implementing planning processes in Brazilian health regions.

Objective: To recognize elements that facilitated or hindered the PlanificaSUS implementation stages.

Methods: A multiple case study was carried out in four pre-selected health regions in Brazil-Belo Jardim (PE), Fronteira Oeste (RS), Sul-Mato-Grossense (MT) and Valença (BA) using systemic arterial hypertension and maternal and child care as tracer conditions.
