Interventional radiology is performed under real-time fluoroscopy, and patients are exposed to a wide range of exposures for a long period of time depending on the examination and procedure. However, studies on radiation protection for patients during an intervention are insufficient. This study aims to evaluate the doses exposed during the intervention and the applicability of 3D printing materials. The organ dose for each intervention site was evaluated using a monte carlo simulatio. Also, the dose reduction effect of the critical organs was calculated when using a shielding device using 3D printing materials. As a result, the organ dose distribution for each intervention site showed a lower dose distribution for organs located far from the x-ray tube. It was analyzed that the influence of scattered rays was higher in the superficial organs of the back of the human body where x-rays were incident. The dose reduction effect on the critical organ using the 3D printing shield showed the highest testis among the gonads, and in the case of other organs, the dose reduction effect gradually decreased in the order of the eye, thyroid, breast, and ovary. Accordingly, it is judged that the 3D printed shield will be sufficiently usable as a shielding device for the radiation protection of critical organs.

Purpose : This study investigated factors affecting the knowledge and attitude of organ procurement from brain dead patients in nurse clinicians. Methods : A survey was conducted with 160 clinical nurses from a university hospital in Seoul. Descriptive statistics, t-tests, an ANOVA, $Scheff{\acute{e}}^{\prime}s$ test, Pearson's correlation coefficient, and a multiple regression analysis were used. Results : The mean score for knowledge of organ procurement from brain dead patients was $12.41{\pm}2.16$ (mean correct answers = 62.1). Factors influencing the knowledge of organ procurement among nurse clinicians were working department (${\beta}=.454$, p < .001), a recent family death (${\beta}=.187$, p = .014), experience recognizing potential brain dead patients (${\beta}=.182$, p = .033), and experience referring to potential brain dead patients (${\beta}=-.192$, p = .048). Conclusion : To ensure effective organ procurement from brain dead patients, it is necessary to continually educate nurse clinicians to improve their attitude and knowledge concerning organ donation.

Chyloperitoneum or chylous ascite after trauma is a rare condition. It can develop after direct injuries of lymphatic vessels or cisterna chyli. Though isolated chyle duct injury has sometimes been reported, chyloperitoneum is generally accompanied by various kinds of damage to other intraabdominal organs. There's still no established therapeutic protocol regarding the treatment of chyloperitoneum when it is accompanied by the serious injuries of intraabdominal organs. We describe a 66-year-old male with serious intraabdominal organ injuries after blunt trauma. In our case, chyloperitoneum developed due to the injuries to the mesenteric lymph vessels and compression of cisterna chyli by hematoma around aorta.

중재방사선을 이용한 의료적 시술이나 진단은 꾸준히 증가하고 있다. 특히 환자에 근접하여 이루어지는 중재방사선시술의 특성상 시술자에 대한 직무피폭의 관리 및 감시가 중요하다. 개인선량계를 통해 측정되는 방사선 방호 실용량인 심부선량은 중재방사선시술의 경우 균질한 방사선장에 의해 전신에 고르게 노출되는 경우가 아니므로 유효선량을 항상 대표할 수는 없다. 따라서 본 연구에서는 C-arm을 이용한 대표적인 중재방사선시술에 대해 수학적 모의피폭체와 몬테카를로 방법을 이용한 계산과 개인선량계를 이용한 실측을 통해 개인선량당량과 장기별 선량을 평가하고자 하였다. 주요 장기별 선량평가 결과는 개인선량계로 측정된 선량 값보다 낮았으나, 갑상선과 같은 장기는 전신 연조직 선량보다 상당히 높은 것으로 평가되었다. 중재방사선시술자에 대한 적절한 방사선방호를 위해 납치마의 착용과 같은 전신 방호와 더불어 갑상선 방호와 같은 추가적인 방호조치가 고려되어야 할 것이다.

Acute fulminant myocarditis (AFM) occurs as an inflammatory response to an initial myocardial insult. Its rapid and deadly progression calls for prompt diagnosis with aggressive treatment measures. The demonstration of its excellent recovery potential has led to increasing use of mechanical circulatory support, especially extracorporeal membrane oxygenation (ECMO). Arrhythmias, organ failure, elevated cardiac biomarkers, and decreased ventricular function at presentation predict requirement for ECMO. In these patients, ECMO should be considered earlier as the clinical course of AFM can be unpredictable and can lead to rapid haemodynamic collapse. Key uncertainties that clinicians face when managing children with AFM such as timing of initiation of ECMO and left ventricular decompression need further investigation.

Liver ischemia-reperfusion injury (IRI) is the main cause of organ dysfunction and failure after liver surgeries including organ transplantation. The mechanism of liver IRI is complex and numerous signals are involved but cellular metabolic disturbances, oxidative stress, and inflammation are considered the major contributors to liver IRI. In addition, the activation of inflammatory signals exacerbates liver IRI by recruiting macrophages, dendritic cells, and neutrophils, and activating NK cells, NKT cells, and cytotoxic T cells. Technological advances enable us to understand the role of specific immune cells during liver IRI. Accordingly, therapeutic strategies to prevent or treat liver IRI have been proposed but no definitive and effective therapies exist yet. This review summarizes the current update on the immune cell functions and discusses therapeutic potentials in liver IRI. A better understanding of this complex and highly dynamic process may allow for the development of innovative therapeutic approaches and optimize patient outcomes.

Bone marrow is a hematological and immunological organ that provides multiple immune cells, including B lymphocytes, and thus plays a critical role in the efficacy of vaccine. We previously demonstrated that Bordetella (B.) bronchiseptica antigen has high immunogenicity in spleen cells, a peripheral immune organ. In this study, we investigated the immunogenicity of B. bronchiseptica antigen in bone marrow cells, a central immune organ. B. bronchiseptica antigen increased the cellular activity of bone marrow cells and significantly enhanced the production of nitric oxide, IL-6, and TNF-${\alpha}$. Bone marrow cells primed with B. bronchiseptica antigen in vivo were harvested and stimulated with the same antigen in vitro. The stimulation of B. bronchiseptica antigen significantly increased the cellular activity and proliferation rate of the primed cells. B. bronchiseptica antigen also greatly induced the production of antigen-specific antibody in the primed cells. Taken together, the present study demonstrated that B. bronchiseptica antigen can stimulate bone marrow cells, a central immune organ, and recall the immune response of the primed bone marrow cells.

Optimal nutrition serves to maintain normal organ function and to preserve body energy stores to guarantee survival during times of shortage of food. Adequate nutrition of intensive care unit (ICU) patients improves outcome, while malnutrition is strongly associated with increased morbidity and mortality rates among critically ill patients. Previously published researches showed that trials of nutritional support in critical illness rarely fulfill basic quality requirements. Nutrition support plays a vital role in the prevention and treatment of nutritional deficiencies in at-risk, critically ill patients. This paper reviewed the challenges in determining critically ill patients' nutrition requirements including nutrition assessment, determination of caloric requirements then providing them with adequate nutrition support while in the ICU with the guidelines published by Society of Critical Care Medicine and American Society for Parenteral and Enteral Nutrition. Nutrition support can be effectively enhanced by using the guidelines.
