Systematic Review of 3D-Printed Ultrasound-able Models in Graduate Medical Education.

This systematic review aimed to identify studies that have created ultrasound-able models for resident procedural training by means of 3D-printing techniques and examine their tissue specific properties. There were 456 articles identified from 3 databases, of which, 35 studies were assessed for eligibility, and 11 total studies were included. All qualitative studies showed improvements in procedural skills and 89% of the quantitative studies showed significant results.

Enhancing the Longitudinal Compressive Strength of Freeform 3D-Printed Continuous Carbon Fiber-Reinforced Polymer Composite Laminate Using Magnetic Compaction Force and Nanofiber Z-Threads.

Low fiber-direction compressive strength is a well-recognized weakness of carbon fiber-reinforced polymer (CFRP) composites. When a CFRP is produced using 3D printing, the compressive strength is further degraded. To solve this issue, in this paper, a novel magnetic compaction force-assisted additive manufacturing (MCFA-AM) method is used to print CFRP laminates reinforced with carbon nanofiber (CNF) z-threads (i.

Investigating the status of whole-body donation across the United States of America.

Dissection of human body donors is a valuable part of anatomical education, research, and clinical training. In the United States, deceased human bodies are predominantly sourced through whole-body donation programs (BDPs) housed by academic institutions. Due to the lack of information regarding BDPs, the aim of this study was to gather information from US BDPs through a survey to better understand the donation process and standard operating procedures of these programs.

Human body donors at academic institutions in the United States of America: An investigative study.

Work with deceased human bodies to enhance anatomical education was first documented in the 3rd century BCE. However, the development of body donation programs provided many new opportunities for medical education. The aim of this study was to investigate the work supported by human body donors at academic institutions in the United States and to evaluate the ethical oversight process and the preparation methods used.

The Push and Pull of Network Mobility: How Those High in Trait-Level Neuroticism Can Come to Occupy Peripheral Network Positions.

Field research shows that people's network positions are determined, at least in part, by their traits. For instance, over time, actors higher in trait-level neuroticism move out to the network periphery. What is unknown is how this happens.

Trends in breast and colorectal cancer screening among U.S. adults by race, healthcare coverage, and SES before, during, and after the great recession.

The aim of this study is examine trends in breast and colorectal cancer screening in the U.S. by race, healthcare coverage, and socio-economic status (SES) before the Great Recession (2003-2005), during the recession (2007-2009), and post-recession/Affordable Care Act (ACA) period (2010 - 2012).

Trends in smoking and obesity among US adults before, during, and after the great recession and Affordable Care Act roll-out.

This study examined trends in smoking and overweight/obesity rates among United States (US) adults ages 40years and older by race and socio-economic status (SES) across three study periods; pre-recession (2003-2005), recession (2007-2009), and post-recession/Affordable Care Act (2010-2012). Data was obtained from the Behavioral Risk Factor Surveillance System (BRFSS), and multivariable regression analysis was used to examine changes in overweight/obesity, smoking, physical activity and smoking cessation rates over the study periods. There were 2,805,957 adults included in the analysis; 65.
