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.

갑상선 영상의학 진료란 갑상선 질환 환자를 영상의학적 방법을 활용하여 질병 진단과 중재적 치료를 하는 의료 행위로 정의될 수 있으며 주요 진료 대상은 갑상선 결절 질환 환자들이다. 갑상선 결절의 진단은 일차적으로 초음파 영상진단과 생검에 의해서 이루어지고 결절의 치료는 비수술적 중재적 치료와 갑상선절제술이다. 갑상선 낭종 혹은 낭성우세 양성 결절에서는 에탄올절제술이 일차적 치료법이고 고주파절제술은 고형 혹은 고형우세 양성 결절과 갑상선 재발암 치료에 적용되고 있다. 갑상선 영상의학 진료는 갑상선 결절 질환 환자의 진단 및 비수술적 치료의 대부분을 담당하는 중요한 임상적 역할을 가지고 있으며, 적절한 환자 진료를 위해서는 표준적 진료 지침에 근거하여 진료가 수행되어야 한다. 환자에게 최적의 갑상선 영상의학 진료를 제공하기 위해서는 영상의학과 외래에서 환자를 진료하는 것이 바람직하며 외래 중심의 갑상선 영상의학 진료를 확대하도록 함께 노력해야 할 시점이다.

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.

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.

목적 : 본 연구의 목적은 작업치료사가 감각통합 중재를 실행하는데 필요한 역량을 기반으로 중재 과정 교육 커리큘럼 개발하고, 중재과정 실시 및 교육만족도 확인을 통하여 대한감각통합치료학회의 역량기반 중재 교육과정을 제시하는데 있다. 연구방법 : 본 연구는 대한감각통합치료학회의 2019년 중재과정에 참여한 작업치료사 9명과 강사 3명을 대상으로 하였다. 중재과정의 교육목표 설정은 참여자 설문조사 방법을 통하여 교육요구 분석방법을 사용하였다. 중재과정의 역량기반 교육 프로그램 초안 및 교육 방법은 강사회의를 통하여 결정하였다. 중재교육과정은 실행계획에 따라 5일간 실시하였으며, 교육 만족도와 각 역량지표에 대한 중재과정 전후의 수행도 변화를 조사하였다. 결과 : 교육목표는 교육요구 분석 결과를 반영하여 '감각통합중재의 임상추론 과정을 학습 하고 적용한다'와 '감각통합중재 원칙을 적용하여 중재한다'로 하였다. 역량기반 중재과정 교육커리큘럼은 교육목표에 따라 Data driven decision making process 및 Ayres Sensory Integration에 관한 강의, 워크샵, 토의, 그리고 사례 중재 등으로 구성하여 총 42시간 교육을 실시하였다. 중재과정 참여자의 교육 만족도는 평균 4.48±0.73이었고, 수퍼바이저의 교육 만족도는 평균 3.92±0.71이었다. 두 집단 모두에서 Data driven decision making process 강의와 중재 목표 수립 강의의 만족도가 가장 높았고, 그룹 활동 및 토의에 대한 만족도가 가장 낮았다. 중재과정 전후, 역량모델의 전문가 역량군에 포함된 분석기술 역량의 두 가지 행동지표가 수행도에서 유의미한 변화를 보였다. 결론 : 본 연구는 교육 개발에 필요한 체계적 과정을 거쳐 교육요구 조사, 교육 커리큘럼 개발과 실시, 교육 만족도 조사를 실행하였다는 점에서 의의가 있다. 대한감각통합치료학회 내의 다른 교육커리큘럼 개발 시 기초자료로 사용될 수 있을 것으로 생각된다.
