A tale of three pumps and a mechanical heart.

Temporary mechanical circulatory support device (tMCS) failure could qualify patients with advanced heart failure to receive a long-term solution. We report on a patient who presented with cardiorespiratory arrest that required a tMCS and developed acute type A aortic dissection. Data Sources: our case adds further evidence regarding the support of a patient with a second (or more) incidence of tMCS.

Bonding interface affects the load-bearing capacity of bilayered composites.

This study evaluated the effect of material type, thickness and composite-composite interfacial adhesion on the load-bearing capacity of the bilayered composite structures. Bilayered cylindrical specimens (diameter=7 mm, height=5 mm) were prepared having three surface-layer thicknesses (1, 1.5, 2 mm) of Gænial Posterior to overlay base-composites [everX Posterior or Smart Dentin Replacement (SDR)].

Effect of interface surface design on the fracture behavior of bilayered composites.

This study aimed to evaluate the effect of different interface designs on the load-bearing capacity of bilayered composite structures (BLS). Cylindrical specimens of BLS were prepared from base composite of 3.5 mm thickness and surface composite of 1.

Bilateral Paravertebral Block versus Thoracic Epidural Analgesia for Pain Control Post-Cardiac Surgery: A Randomized Controlled Trial.

Background: Adequate pain control after cardiac surgery is essential. Paravertebral block is a simple technique and avoids the potential complications of epidural catheters. The objective of this study is to compare the effect of ultrasound-guided bilateral thoracic paravertebral block with thoracic epidural block on pain control after cardiac surgery.

Influence of increment thickness on dentin bond strength and light transmission of composite base materials.

Objectives: Bulk-fill resin composites (BFCs) are gaining popularity in restorative dentistry due to the reduced chair time and ease of application. This study aimed to evaluate the influence of increment thickness on dentin bond strength and light transmission of different BFCs and a new discontinuous fiber-reinforced composite.

Materials And Methods: One hundred eighty extracted sound human molars were prepared for a shear bond strength (SBS) test.

The effect of rubber dam on atmospheric bacterial aerosols during restorative dentistry.

Rotatory dental instruments generate atmospheric aerosols that settle on various surfaces, including the dentist's head. The aim of this study was to quantitatively assess bacterial contamination of the dentist's head and to evaluate whether it is affected by using a rubber dam. Senior dental students (n=52) were asked to wear autoclaved headscarves as collection media while performing restorative dental treatment with and without a rubber dam.
