Management of Patients with Ischemic Heart Disease in Spine Surgery.

In ischemic heart disease (IHD), the myocardium does not receive enough blood and oxygen. Although the IHD-related mortality rate is decreasing, the risk remains and is a major predictor of cardiac complications following noncardiac surgery. Given the increase in the older population, the number of patients with spinal diseases requiring surgery is increasing.

Complications and recovery patterns after blunt splenic injury: Recommended duration and follow-up methods.

Background: Splenic artery embolization (SAE) is commonly employed as a non-operative management technique for splenic injury. Nonetheless, information on follow-up duration and methods, and the natural course of splenic infarction after SAE is limited. Thus, this study is aimed to analyze the patterns of complications and recovery of splenic infarction after SAE and to determine the appropriate follow-up duration and method.

The influence of different hinge position on PTS during HTO: comparison between open-wedge and closed-wedge HTO.

Purpose: The purpose of this study was to determine the significance of hinge position through comparison between open-wedge and closed-wedge high tibial osteotomy (HTO) and to determine the ideal hinge position to minimize the effect of HTO on the posterior tibial slope (PTS) and medial proximal tibial angle (MPTA).

Methods: Procedures were performed on 32 cadaveric knees using open-wedge HTO with the standard hinge position or a low hinge position or closed-wedge HTO with the standard hinge position or a low hinge position. To define the standard hinge position in open wedge HTO, we drew a line 3-cm inferior to the medial tibial plateau toward the fibular head and located the intersection of this line with a longitudinal line 1-cm medial to fibular shaft.

Material And Methods: This retrospective study included 110 patients who underwent non-ECG-gated high-pitch CTA (group 1) or hybrid ECG-gated CTA (group 2) of the entire aorta.

A roadmap to improve usage items to enhance the operational effectiveness of occupational safety and health management expense in Korean construction.

Occupational safety and health management expense (OSHE) in construction industry is a statutory expense used for the purpose of preventing occupational accident and health disorders for construction workers, and the detailed usage standard is stipulated in the law and regulations governed by the Ministry of Employment and Labor in Korea. Previous studies focused on improvement of the accounting rate of OSHE and institutional improvement to secure usage transparency, but analysis showed that the review of improvement directions for usage items was insufficient. Considering recent trends, such as the increase in industrial demand to improve existing usage items and the introduction of various smart safety products incorporating the Fourth Industrial Revolution technology, it is expected that it will be necessary to review ways to improve the usage items to enhance the operational efficiency of OSHE.
