Inaccuracy of brachial blood pressure and its potential impact on treatment and aortic blood pressure estimation.

Objective: Although brachial cuff SBP is universally used to guide hypertension management, it can differ significantly from intraarterial SBP. We examine the potential impacts of cuff-to-intraarterial brachial SBP (bSBP) mismatch on hypertension treatment and accuracy towards central SBP.

Methods: In 303 individuals, cuff bSBP (CUFF-bSBP) and central SBP were measured using a Mobil-o-Graph simultaneously to intraarterial bSBP (IA-bSBP) and aortic SBP.

Ultrasound guidance versus anatomical landmark approach for femoral artery access in coronary angiography: A randomized controlled trial and a meta-analysis.

Objectives: The objective was to assess the effect of ultrasound (US)-guidance compared to the anatomical landmark (AL) approach in patients requiring femoral artery (FA) access for coronary angiography/percutaneous coronary interventions (PCI).

Background: US-guidance has been proposed as a strategy to optimize FA access, potentially leading to decreased vascular complications.

Methods: Patients requiring FA access for coronary angiography/PCI were randomized to the US-guided or AL approaches.

Development and in vitro validation of a simplified numerical model for the design of a biomimetic femoral stem.

Background: Dense and stiff metallic femoral stems implanted into femurs for total hip arthroplasties produce a stress shielding effect since they modify the original load sharing path in the bony structure. Consequently, in the long term, the strain adaptive nature of bones leads to bone resorption, implant loosening, and the need for arthroplasty revision. The design of new cementless femoral stems integrating open porous structures can reduce the global stiffness of the stems, allowing them a better match with that of bones and provide their firm fixation via bone ingrowth, and, thus reduce the risk of implantation failure.

Femoral stem incorporating a diamond cubic lattice structure: Design, manufacture and testing.

Background: The current total hip prostheses with dense femoral stems are considerably stiffer than the host bones, which leads to such long-term complications as aseptic loosening, and eventually, the need for a revision. Consequently, the lifetime of the implantation does not match the lifetime expectation of young patients.

Method: A femoral stem design featuring a porous structure is proposed to lower its stiffness and allow bone tissue ingrowth.

Median sternotomy: comparative testing of braided superelastic and monofilament stainless steel sternal sutures.

A new device to reduce the risk of post-operative complications following median sternotomy is proposed, made of a superelastic shape memory alloy and called a braided tubular superelastic (BTS) suture. This study compares the viability of the BTS suture with that of the standard monofilament stainless steel (MSS) suture. A custom test bench was developed to perform comparative testing of the two sternal closure systems.
