Impacts of residual 3D printing metal powders on immunological response and bone regeneration: an in vivo study.

Residual powder is a defect in powder bed fusion-based additive manufacturing (3D printing), and it is difficult to completely remove it from as-printed materials. In addition, it is not necessary to apply 3D printed implants with residual powder in the clinic. The immunological response triggered by the residual powder is an important area of study in medical research.

Association of Office and Ambulatory Blood Pressure with Left Ventricular Structure and Function in Hypertensive Patients.

Objective: The current study was to evaluate the association of office blood pressure (OBP) and 24h ambulatory blood pressure (ABP) with left ventricular (LV) structure and function in hypertensive patients. Whether the association was modified by sex was also evaluated.

Methods: A total of 694 hypertensive patients without cardiovascular disease were retrospectively included from the inpatient clinic.
