OBJECTIVES: This study aims to investigate the risk of posttraumatic stress disorder (PTSD) and its related factors among firefighters dispatched to the rescue sites after the Great Japanese Earthquake in 2011. METHODS: Among 104 male firefighters dispatched to rescue sites after the Great Japanese Earthquake, 73 firefighters were assessed. The 73 firefighters completed questionnaires, which include general characteristics, an impact of event scale-revised Korean version (IES-R-K), a coping checklist, a scale of perceived social support, and a post-traumatic stress diagnostic scale (PDS). The data was analyzed to find factors related to PTSD risk. RESULTS: The mean value of age and work tenure in this study were 38.6 years (SD=5.7) and 11.6 years (SD=6.0), respectively. The number and rate of the PTSD high-risk group in dispatched firefighters in this study was 7 cases and 9.6% using IES-R-K, with an over 25-point cutoff score. The mean rank of tenure, 53.5 in the PTSD high-risk group (n=7), was significantly higher than that of 32.2 in the PTSD low-risk group (n=66). The mean rank of assessable support, 20.2 in the PTSD high-risk group was significantly lower than that of 38.7 in the PTSD low-risk group. In logistic analysis of model 1 including PDS in independent variables, were associated with being a PTSD high-risk group as in the following: higher PDS score (OR 2.18, 95% CI: 1.07~4.46), longer tenure (OR 3.42, 95% CI: 1.01~11.89), more using coping method (OR 1.35, 95% CI: 1.00~1.81), and lower perceptions of social support (OR 0.84, 95% CI: 0.72~0.97). In logistic analysis of model 2 without PDS in independent variables, more using coping method (OR 1.14, 95% CI: 1.01~1.28) and lower perceptions of social support (OR 0.95, 95% CI: 0.91~0.98) were associated with being a PTSD high-risk group. CONCLUSION: The PTSD high-risk group in dispatched firefighters indicated that their odds ratios were increased when they used more coping methods under specific stress conditions and had lower perceptions of social support. Therefore, for those, who might be dispatched to overseas, the psychological support approach should be considered to produce effective coping methods against traumatic events and to be aware of abundant resources for social support regarding the problem.

Stent fracture is a complication following implantation of drug eluting stents and is recognized as one of the risk factors for in-stent restenosis. We present the first case of successfully managing a stent fracture and subsequent migration of the fractured stent into the ascending aorta that occurred during repeat revascularization for in-stent restenosis of an ostium of saphenous vein graft after implantation of a zotarolimus-eluting stent. Although the fractured stent segment had migrated into the ascending aorta with a pulled balloon catheter, it was successfully repositioned in the saphenous vein graft using an inflated balloon catheter. Then, the fractured stent segment was successfully connected to the residual segment of the zotarolimus-eluting stent by covering it with an additional sirolimuseluting stent.

An 80-year old woman suffered from sudden onset of chest pain and dyspnea, and visited the emergency room. She received stent implantation with a biolimus A9-eluting stent (Nobori(R) 3.0x24 mm) at a the mid-portion of the left anterior descending artery 5 months prior to admission. The emergency 5-month follow-up angiogram was performed under the impression of late stent thrombosis. The follow-up angiogram showed subtotal occlusion at the mid-portion of the left anterior descending artery, which was the same segment of previous stent implantation 5 months ago. Immediately after thrombus aspiration with the thrombus aspiration catheter, the optical coherence tomography showed layered appearance of neointimal hyperplasia and neointimal rupture within the previously stented segment. Thus, neointimal rupture within accelerated growth of neointimal tissue was observed within a relatively shorter period (i.e., about 5 months) after stent implantation.

BACKGROUND/AIMS: Human immunodeficiency virus-associated pulmonary arterial hypertension (HIV-PAH) is a complication of HIV infection. Due to improvements in HIV survival rates following the introduction of highly active antiretroviral therapy, HIV-PAH has become an important cause of HIV-related morbidity. Thus, the objective of this study was to explore the prevalence and characteristics of HIV-PAH. METHODS: Ninety-two patients were enrolled in the study from March to August 2010. We investigated clinical characteristics and performed echocardiography. HIV-PAH was defined as having a mean pulmonary arterial pressure (mPAP) > or = 25 mmHg based on Mahan's equation, without lung disease or heart disease. The HIV-PAH-possible group was defined as having a tricuspid regurgitation velocity (TRV) of 2.9-3.4 m/s and a pulmonary arterial systolic pressure (PASP) of 37-50 mmHg. RESULTS: Fifteen patients (16.3%) met the criteria of HIV-PAH based on mPAP. With respect to TRV, six patients met the criteria of the HIV-PAH-possible group. Based on the criteria of mPAP, the duration of HIV infection was not different with or without HIV-PAH. HIV RNA titers and CD4 T cell counts tended to be higher in HIV-PAH patients (8,607 +/- 11 vs. 1,067 +/- 64 copies/mL, p = 0.371; 471 +/- 148 vs. 499 +/- 252 cells/mm3, p = 0.680, respectively). Echocardiographic indices of the right ventricle were significantly deteriorated in the HIV-PAH group as compared with the non-HIV-PAH group (TASPE: 20.52 vs. 23.2, p = 0.001; Tei index: 0.42 vs. 0.39, p = 0.037). In a multivariate regression analysis, HIV activity factors (HIV duration, HIV RNA titer, and CD4 cell count) were not associated with echocardiographic indices of PAH (mPAP, PASP, and pulmonary vascular resistance). CONCLUSIONS: In this study, the prevalence of HIV-PAH was comparable to that of previous studies.

OBJECTIVES: This study developed an information and communication technology (ICT)-based comprehensive health and social-needs assessment (CHSNA) system based on the International Classification of Functioning, Disability, and Health (ICF) with the aim of enhancing person-centered community care for community residents and supporting healthcare professionals and social workers who provide healthcare and social services in the community. METHODS: Items related to a CHSNA tool were developed and mapped with ICF codes. Experts validated the CHSNA system design and process using the Delphi method, and a pilot test of the initial version of the system was conducted. RESULTS: The following three steps of CHSNA were embedded in the system, which had a user-friendly screen and images: basic health assessment, life and activity assessment, and in-depth health assessment. The assessment results for the community residents were presented with visualized health profiles, including images, graphs, and an ICF model. CONCLUSIONS: The developed CHSNA system can be used by healthcare professionals, social workers, and community residents to evaluate the reasoning underlying health and social needs, to facilitate the identification of more appropriate healthcare plans, and to guide community residents to receive the best healthcare services. A CHSNA system can improve the implementation of standardized terminology utilizing the ICF and the accuracy of needs assessments of community residents.

Immunotherapy has revolutionized and opened a new paradigm for cancer treatment. In the era of immunotherapy and molecular targeted therapy, precision medicine has gained emphasis, and an early response assessment is a key element of this approach. Treatment response assessment for immunotherapy is challenging for radiologists because of the rapid development of immunotherapeutic agents, from immune checkpoint inhibitors to chimeric antigen receptor-T cells, with which many radiologists may not be familiar, and the atypical responses to therapy, such as pseudoprogression and hyperprogression.Therefore, new response assessment methods such as immune response assessment, functional/molecular imaging biomarkers, and artificial intelligence (including radiomics and machine learning approaches) have been developed and investigated.Radiologists should be aware of recent trends in immunotherapy development and new response assessment methods.
