The purpose of this study was to develop the framework for the relapse prevention program. The study examined interventional needs for a relapse prevention program among adult substance abusers. The total of 107 adult substance abusers were surveyed and asked about their interventional needs for the relapse prevention program. The questionnaire was developed by the researcher on the basis of several theories such as problem behavior theory, ecologica1-developmental theory, social support theory, and coping theory. Results showed that admit substance abusers wanted the program to deal with such issues related with individual, family, social skills, and drugs. The implications of study findings were discussed.

Background: Epidermal growth factor-like domain multiple 7 (EGFL7), recently identified as a secreted protein regulated by oxygen exposure, plays a critical role in promoting metastasis of hepatocellular carcinoma (HCC). Transcatheter arterial embolization (TAE) is widely used for treatment of HCC, resulting in hypoxia in tumors and surrounding liver tissues. Accordingly, we proposed the hypothesis that there could be a relationship between expression of EGFL7 and response to TAE. Materials and Methods: We established a rabbit VX2 liver tumor model using percutaneous puncture technique guided by computed tomography. TAE and sham embolization were performed and the results were confirmed by MRI 3 weeks after inoculation. We investigated the EGFL7 expression of the two groups at 6h and 3 days after intervention by means of immunohistochemistry and Western blotting. Results: Immunohistochemical staining demonstrated that the levels of EGFL7 protein significantly increased in the TAE-treated tumors compared with the control group at 6 hours (P=0.031) and 3 days (P=0.020) after intervention. Meanwhile, the relative EGFL7 protein detected in TAE group also up-regulated compared with the control group at 6 hours (P=0.020) and 3 days (P=0.024) after intervention. Conclusions: This study reveals an increase of EGFL7 expression in rabbit VX2 liver tumors after TAE. The role of EGFL7 in HCC, especially its biological behavior after TAE, needs further investigation.

Thyroid radiology practice is a medical practice in which thyroid diseases are diagnosed using imaging modality and treated by imaging-based interventional techniques, and the primary care target is thyroid nodular disease. Diagnosis of thyroid nodules is primarily done by ultrasound imaging and biopsy; thyroid nodules can be treated by non-surgical interventional treatment and thyroidectomy. Ethanol ablation is the first-line treatment for cystic benign nodules, and radiofrequency ablation is used for the treatment of benign solid nodules and recurrent thyroid cancers. Thyroid radiology practice has an essential clinical role in diagnosis and nonsurgical treatment of thyroid nodular diseases, and treatment should be performed based on standard care guidelines for proper patient care. In order to provide the best care to patients with thyroid nodular disease, it is desirable to treat patients in the radiology outpatient clinic. Thyroid radiology practice centered on outpatient clinic practice needs to be expanded.

Purpose: The Hybrid care environment, combining interventional procedures and surgeries in one space, is crucial for managing complex diseases, responding to emergencies, and reducing recovery times and pain. This study provides foundational data for creating architectural guidelines for a Hybrid Operating Unit in a general hospital's surgical department, focusing on cardiovascular care. Methods: The study analyzed the spatial and configuration types of the Vascular Angiography Unit and the Cardiac Operating Unit, which are the basic components of the Hybrid Operating Unit, through a literature review. Based on the initial research findings, interviews with experts were conducted. Results: In the Hybrid Operating Process, the study proposed spatial configuration alternatives that consider the positioning of medical staff and the types and arrangement changes of equipment, including Angiography, Heart-lung machines, and other surgical tools and instruments. Implications: The integration of the two units leads to increased diversity and demand for medical staff, equipment, and supplies during surgical and interventional procedures. Therefore, strategic spatial configurations and equipment placement are necessary to effectively respond to these needs.

Remote control intervention surgery robotic system improves treatment effect on cardiovascular patients and reduces X-ray exposure. However, at the time of the first procedure, CT (computerized tomography) and other ultrasound diagnostic equipment should be used because the operator must insert the cannula directly into the patient's leg. Improvements to this have been un-met-needs of hospitals. In this paper, we developed a system that can insert the cannula intuitively and quickly by displaying blood vessels at a glance through the system using smart wearable glasses. The core development method is as follows. In order to project augmented reality onto the surgical image, CT scan angiography image is extracted and processed. In the process, three CT-Markers are used to create a coordinate system of blood vessel images. Additionally, a reference marker is photographed on a single camera to obtain a camera coordinate system. Since the CT marker and the reference marker are in the same position, 3D registration is performed. In the text, a detailed explanation will be given.

Acute myocardial infarction due to coronary occlusion by emboli originating from the prosthetic valve thrombosis is very rare but fatal disease which needs immediate diagnosis and urgent treatment. We report a case of acute myocardial infarction after left anterior descending embolic occlusion in whom had previous mitral valve replacement. Redo valve replacement following the interventional catheterization and anti platelet therapy lead to successful results.

The application of ultrasound (US) in pain medicine has been a rapidly growing field since the 2000s. Musculoskeletal injections, peripheral nerve blocks, and neuraxial injections under US guidance have been acknowledged for managing chronic pain. Although many studies on US-guided pain procedures have been published, there needs to be a classification system to evaluate which image device, the US or fluoroscopy, is clinically and technically better in various pain interventions. Therefore, this narrative review introduces the classification system for the US-guided pain procedures according to their clinical and technical outcomes and designates US-guided pain procedures into one of the four categories by reviewing previous prospective randomized comparative trials.

Background: Recently, cancer immunotherapy has become standard for cancer treatment. Immunotherapy not only treats primary tumors, but also prevents metastasis and recurrence, representing a major advantage over conventional cancer treatments. However, existing cancer immunotherapies have limited clinical benefits because cancer antigens are often not effectively delivered to immune cells. Furthermore, unlike lymphoma, solid tumors evade anti-cancer immunity by forming an immune-suppressive tumor microenvironment (TME). One approach for overcoming these limitations of cancer immunotherapy involves nanoparticles based on biomaterials. Main body: Here, we review in detail recent trends in the use of nanoparticles in cancer immunotherapy. First, to illustrate the unmet needs for nanoparticles in this field, we describe the mechanisms underlying cancer immunotherapy. We then explain the role of nanoparticles in the delivery of cancer antigens and adjuvants. Next, we discuss how nanoparticles can be helpful within the immune-suppressive TME. Finally, we summarize current and future uses of nanoparticles with image-guided interventional techniques in cancer immunotherapy. Conclusion: Recently developed approaches for using nanoparticles in cancer immunotherapy have enormous potential for improving cancer treatment. Cancer immunotherapy based on nanoparticles is anticipated not only to overcome the limitations of existing immunotherapy, but also to generate synergistic effects via cooperation between nanoparticles and immune cells.

Pulmonary atresia with intact ventricular septum (PAIVS) is rare, less than 1% of congenital heart disease. It needs a therapeutic approach according to its individual morphologic feature. Surgical treatment of valvotomy and modified Blalock-Taussig shunt or non-surgical interventional catheter balloon valvuloplasty can be used for mild to moderate hypoplasia of right ventricle. Fontan operation can be considered for less optimum morphological substrate of two ventricular repair. A 3-day-old male neonate was admitted with cyanosis and cardiac murmur. On echocardiogram, he had membranous pulmonary atresia with intact ventricular septum, normal sized tripartite right ventricle, large atrial septal defect with right-to-left shunt, small sized patent ductus arteriosus, and moderate tricuspid regurgitation. He was treated with intravenous continuous infusion of prostaglandin $E_1$ ($PGE_1$) at once. On the third day of hospitalization, Balloon valvuloplasty was performed. After insertion of patent ductus arteriosus stent on the tenth day, $PGE_1$ infusion was discontinued. On the fifteenth day, he was discharged. Now, he is 9 months old and has nearly normal cardiac structure and function with 97% of percutaneous oxygen saturation.

Objective : The purpose of this study is to develop educational goals, training content, and training methods for the intervention course of the Korean Academy of Sensory Integration (KASI) and to conduct competency-based intervention courses based on the competency model for sensory integration intervention. Methods : This study was conducted on work therapists who participated in the 2019 intervention course of KASI. In the first phase, educational needs were analyzed to set goals for the interventional course. In the second phase, a meeting of researchers drafted the intervention course education program and the methods of education, and the intervention course was conducted. In the third phase, the changes in educational satisfaction and performance level pre- and post-intervention course for each competency index were investigated. Results : The educational goals of "learning and applying the clinical reasoning process of sensory integration intervention" and "intervention by applying the principle of sensory integration intervention" were set after reflecting on the results of the analysis of the educational requirements. The length of the competency-based intervention course was 42 hours. The average education satisfaction level of participants in the arbitration process was 4.48±0.73, and the average education satisfaction level of the supervisor was 3.92±0.71. In both groups, the most satisfying curriculums were the data-driven decision-making process and the intervention goal-setting lecture. But the satisfaction level of was the lowest. Before and after the intervention course, there were significant changes in the performance of the two behavioral indicators of the analytic skills in the expertise competency cluster of the competency model. Conclusion : This study is meaningful in that it conducted a survey of educational needs, the development and implementation of an educational curriculum, and an education satisfaction survey through systematic courses necessary for education development.
