The development of reliable methods to diagnose acute kidney injury is essential to allow the adoption of early therapeutic interventions and evaluate their effectiveness. Based on the fact that kidney injury molecule-1 (KIM-1) expression levels in kidneys are markedly upregulated early after a damage event, here we developed a noninvasive KIM- 1-based molecular imaging technique to detect kidney injury. First, we took advantage of a phage-display platform to select small peptides demonstrating a specific high binding affinity to KIM-1. The promising candidate was conjugated with fluorescent probes, and its imaging potential was validated in vitro and in vivo. This peptide, with the sequence CNRRRA, not only showed a high imaging potential in vitro, allowing a strong detection of KIM-1 expressing cells by microscopy and flow cytometry but also generated a strong kidney-specific signal in live-imaging in vivo experiments in the context of a drug-induced kidney-injury mouse model. Our data overall suggest that the CNRRRA peptide is a promising probe to use in the context of in vivo imaging for the detection of KIM-1 overexpression in damaged kidneys.

Background: Micafungin, a potent inhibitor of 1,3-β-D-glucan synthase, is a novel antifungal agent of the echinocandin class. In vitro study showed that micafungin was effective against Aspergillus species as well as Candida species, but clinical data on the prophylactic efficacy against invasive fungal infections (IFIs) other than candidiasis are still lacking. Materials and Methods: We identified 60 consecutive adult hematopoietic stem cell transplantation (HSCT) recipients who received at least 3 doses of micafungin during neutropenic period. Micafungin was started as an alternative in patients who were intolerant or had adverse events (AEs) to primary prophylactic antifungal agents. We retrospectively reviewed the medical records and analyzed the efficacy and safety of micafungin for prophylaxis against IFIs. Results: The patients either had autologous (n=9) or allogeneic (n=51: 1 syngeneic, 24 sibling, 26 unrelated donor) HSCT. Itraconazole oral solution (n=58) was the most frequently used first line antifungal agent for prophylaxis and was administered for median 11 days. The most frequent cause of switch to micafungin was vomiting (n=42). The duration of neutropenia and micafungin administration was median 13 and 12 days, respectively. A successful outcome was achieved in 45 (75%) patients. Empirical antifungal therapy was initiated in 13 (22%) patients. There were 2 cases (3.3%) of breakthrough fungal infections which comprised a probable invasive pulmonary aspergillosis and a possible invasive fungal sinusitis. There was no case of invasive candidiasis. A total of 53 (88%) patients experienced at least one AE regardless of causality during micafungin administration. The most frequent AEs were hypokalemia, vomiting, diarrhea, and elevated serum aspartate aminotransferase or alanine aminotransferase. Among the aforementioned AEs, only 1 case of diarrhea could be classified as a probable relation with micafungin when causality was assessed. There was no AEs that caused discontinuation of micafungin. Conclusions: Micafungin seems to be a safe and effective agent for prophylaxis of IFIs including aspergillosis as well as candidiasis in HSCT recipients. However, further large, prospective, and randomized comparative studies are warranted for aspergillosis.

Background : Gastric cancer is the most common malignant tumor in Korea. surgical operation is one of the major treatment modalities for gastric cancer patients. Therefore, gastrectomy is one of the most common procedures in General Surgery. There were variation in length of hospital stay and medical treatment for gastrectomy between three surgeons at Asan Medical Center. Clinical pathways have received considerable attention as a tool for recucing the medical practice variation, increasing the efficiency of care process, and improving the quality of care. The aim of this study was to evaluate the effect of a clinical pathway for gastrectomy in gastric cancer patients. Methods : The clinical pathway for gastrectomy was developed and implemented by a multidisciplinary group in Asan Medical Center. A computerized clinical pathway program was developed and revised after a pilot test. A total of 145 patients underwent gastrectomy by three surgeons at Asan Medical Center. We compared the length of hospital stay, patient satisfaction, and unplanned readmission rate between the pre-pathway group(n=67) and the post-pathway group(n=78). We also investigated the degree of satisfaction among the physicians and nurses who were main end-users of the clinical pathway. Results : The clinical pathway was applied to all target patients. The average length of hospital stay was shortened from 12.7days to 10.6days(p<0.01). The degree of patient satisfaction with the care process changed from 90.3% to 89.2% after the implementation of the clinical pathway, but the difference was of satistically significant(p=0.761). Unplanned readmission rate was 2.9% in the pre-pathway group. More than 90% of physicians and nurses answered that the clinical pathway had been a useful tool in their medical practice. Conclusions : The findings of the study demonstrated that implementation of the clinical pathway for gastrectomy produced substantial reduction in the length of hospital stay while improving the quality of patient outcomes. The computerized clinical pathway program can be used as one of the powerful patient management tools for reducing the practice variations and increasing the efficiency of care process in Korea hospital settings.

Objectives : The purpose of this study was to examine the prevalence of personality disorders between normal control group and hospitalized methamphetamine abuse or dependent patients and, among the latter, the influence of comorbid personality disorder on their global assesment function and general characteristics. Methods : Subjects were 50 non-methamphetamine abuse or dependent persons in the general population group and 50 methamphetamine abuse or dependent patients admitted to the psychiatric hospital. Methamphetamine abuse or dependence and the global assesment function were diagnosed according to DSM-Ⅳ, and the presence of personality disorder was assessed with the PDQ-4+. Results : In the normal control group, 34% of subjects had at least one personality disorder and the average number of personality disorder was 3.94 per person. In the methamphetamine abuse or dependent group, 64% of the patients had at least one personality disorder and the average number .of personality disorder was 4.72 per patient. The presence of comorbid personality disorder were not associated with onset age, use dosage and the number of admission or arrest among the methamphetamine abuse or dependent group. But, when methamphetamine abuse or dependent patients had more than three personality disorders, the global assessment function was impaired. Conclusion : In our study, substance use disorder patients had the higher possibility of comorbid personality disorder in Korea, and among substance use disorder patients, those with comorbid personality disorders were associated with the greater global impairment.
