Staphylococcus aureus is an important cause of human infections, and it is also a commensal that colonizes the nose, axillae, vagina, throat, or skin surfaces. S. aureus has increasingly been recognized as a cause of severe invasive illness, and individuals colonized with this pathogen are subsequently at increased risk of its infections. S. aureus infection is a major cause of skin, soft tissue, respiratory, bone, joint, and endovascular disorders, and staphylococcal bacteremia may cause abscess, endocarditis, pneumonia, metastatic infection, foreign body infection, or sepsis. The authors describe a case of a fisherman who died of sepsis on a fishing boat during sailing out for fish. The autopsy shows paravertebral abscess, pus in the pericardial sac, infective endocarditis with vegetation on the aortic valve cusp, myocarditis, pneumonia and nephritis with bacterial colonization, and also liver cirrhosis and multiple gastric ulcerations.

BACKGROUND: The object of this study was to assess the validity and reliability of the Korean versions of chronic obstructive pulmonary disease assessment test (CAT) and Dyspnea-12 Questionnaire for patients with chronic pulmonary obstructive disease (COPD). METHODS: For the 127 COPD patients, we obtained the Korean versions of the 3 questionnaires being tested: St George's Respiratory Questionnaire (SGRQ), CAT, and Dyspnea-12 with spirometric measurements. To assess the validity of CAT and Dyspnea-12, their correlation with SGRQ was evaluated. To assess the reliability of CAT and Dyspnea-12, Cronbach's alpha coefficient was evaluated. RESULTS: The mean age of patient participants was 68.6+/-7.5 years; 97.6% were male. The SGRQ score was correlated with the scores of the Korean version of CAT (r=0.71, p<0.0001) and Dyspnea-12 (r=0.73, p<0.0001). The Cronbach's alpha coefficient for the CAT and Dyspnea-12 were 0.77 and 0.78, respectively. CONCLUSION: The Korean versions of CAT and Dyspnea-12 were shown to be valid and reliable for the Korean COPD patients.

In addition to cellular damage, ischemia-reperfusion (IR) injury induces substantial damage to the mitochondria and endoplasmic reticulum. In this study, we sought to determine whether impaired mitochondrial function owing to IR could be restored by transplanting mitochondria into the heart under ex vivo IR states. Additionally, we aimed to provide preliminary results to inform therapeutic options for ischemic heart disease (IHD). Healthy mitochondria isolated from autologous gluteus maximus muscle were transplanted into the hearts of Sprague–Dawley rats damaged by IR using the Langendorff system, and the heart rate and oxygen consumption capacity of the mitochondria were measured to confirm whether heart function was restored. In addition, relative expression levels were measured to identify the genes related to IR injury. Mitochondrial oxygen consumption capacity was found to be lower in the IR group than in the group that underwent mitochondrial transplantation after IR injury (p < 0.05), and the control group showed a tendency toward increased oxygen consumption capacity compared with the IR group. Among the genes related to fatty acid metabolism, Cpt1b (p < 0.05) and Fads1 (p < 0.01) showed significant expression in the following order: IR group, IR + transplantation group, and control group. These results suggest that mitochondrial transplantation protects the heart from IR damage and may be feasible as a therapeutic option for IHD.
