Objective: To investigate the feasibility of a public health center-based aerobic and resistance training program for primary prevention of cardiovascular disease in people with visual, auditory, or physical/brain impairments. Methods: The study included 25 adults aged >40 years who lived in Cheorwon-gun in South Korea, had a disability registered for visual, auditory, or physical/brain impairments under the Disability Welfare Act, and had either known cardiovascular disease or two or more risk factors for cardiovascular disease. The program comprised four education sessions and 12 weeks of customized aerobic and strengthening exercises performed twice a week at moderate intensity, with each exercise session lasting for 1 hour. The body mass index (BMI), percent body fat, 6-minute walk distance (6MWD), and 30-second sit-to-stand test results were measured at baseline and on program completion. Results: Seventeen subjects (68%) completed the program. There were significant decreases in BMI and percent body fat (both p<0.05), with a significant increase in 30-second sit-to-stand strength (p<0.05) but no changes in the 6MWD. In subjects with visual or auditory impairments, BMI and percent body fat were significantly decreased after the program; however, there was no significant change in the results of the 30-second sit-to-stand strength test or the 6MWD. Conclusion In people with disabilities, a 3-month community-based exercise program can decrease body mass index and percent body fat and increase sit-to-stand strength. The 30-second sit-to-stand test may be a useful measure of the strength and endurance of the lower extremities in people with disabilities.

This review summarizes 1) the general characteristics of the reviewed literature (authors, year of publication, research method, research subjects), 2) the characteristics of the identified rehabilitation nursing interventions (interventionist, intervention type, period, measurement tool), 3) the effects of the rehabilitation nursing interventions, and the academic and clinical implications. Conclusion This scoping review provides theoretical basis for the future development of rehabilitation nursing interventions for stroke patients with hemiplegia.

We report the case of a 64-year-old male with persistent atrial fibrillation (AF) terminated by ethanol infusion into vein of Marshall as add-on therapy. Three-dimensional automated complex fractionated atrial electrogram (CFAE) during AF revealed clustering of CFAE at perimitral isthmus (PMI) and its unipolar mapping showed rotor-like activation, which was suggested to be critical in the perpetuation of AF. AF was organized to atrial tachycardia (AT) by 100% ethanol infusion in the vein of Marshall. Adjunctive radiofrequency ablation at PMI successfully terminated AT and led to bidirectional block of PMI.

BACKGROUND/AIMS: Obscure gastrointestinal bleeding (OGIB) accounts for 5% of all gastrointestinal (GI) bleeding cases. Dynamic contrast-enhanced multidetector-row CT (DCE-MDCT) is not generally recommended in OGIB patients due to its low sensitivity. However, it can be used to quickly and simply diagnose OGIB according to some guidelines. The aim of this study was to evaluate the clinical efficacy of DCE-MDCT in OGIB patients. METHODS: We retrospectively analyzed the medical records of 362 patients who underwent DCE-MDCT between March 2009 and January 2014. A total of 45 patients diagnosed with OGIB were included in this study. Their baseline characteristics and treatment procedure were analyzed retrospectively. The positive rates of DCE-MDCT for the detection of bleeding and associated factors were assessed. RESULTS: The mean age of the patients was 59 years, and males represented 51.1%. Melena was the most common symptom (44.4%). Positive rate of DCE-MDCT findings was 20.0% (9/45). Among these patients, intraluminal contrast extravasation was found in 5 patients (55.6%) and intraluminal hematoma or mass lesions were found in 2 patients each (22.2%). Thirty nine patients (86.7%) underwent conservative management, and 6 patients (13.3%) underwent specific treatment, such as endoscopic treatment, embolization, or surgery. Patients who showed positivity in DCE-MDCT more frequently received specific treatment compared with those who were negative (44.4% vs. 5.6%, p=0.010). CONCLUSIONS: Although DCE-MDCT showed a low positive rate (20.0%), positive findings of DCE-MDCT could lead to specific treatment. Positive DCE-MDCT findings play a useful role in the management of patients with OGIB.

Candida species is indigenous fungus of healthy individuals, and frequently found in sputum culture. Candida isolation from the respiratory tract is not generally considered as a marker of lung infection, and definitive diagnosis of Candida pneumonia is confirmed by tissue biopsy. A few cases of Candida pneumonia pathologically confirmed by transthoracic needle aspiration of mycetoma have been reported. In Korea, a case of Candida pneumonia diagnosed by bronchial washing and blood culture was reported, but there is no case report diagnosed by biopsy. We report a case of Candida pneumonia diagnosed by endobronchial biopsy, and antifungal therapy resulted in successful resolution of the pneumonia.

CTHRC1 (collagen triple-helix repeat-containing 1), a protein secreted during the tissue-repair process, is highly expressed in several malignant tumors, including pancreatic cancer. We recently showed that CTHRC1 has an important role in the progression and metastasis of pancreatic cancer. Although CTHRC1 secretion affects tumor cells, how it promotes tumorigenesis in the context of the microenvironment is largely unknown. Here we identified a novel role of CTHRC1 as a potent endothelial activator that promotes angiogenesis by recruiting bone marrow-derived cells to the tumor microenvironment during tumorigenesis. Recombinant CTHRC1 (rCTHRC1) enhanced endothelial cell (EC) proliferation, migration and capillary-like tube formation, which was consistent with the observed increases in neovascularization in vivo. Moreover, rCTHRC1 upregulated angiopoietin-2 (Ang-2), a Tie2 receptor ligand, through ERK-dependent activation of AP-1 in ECs, resulting in recruitment of Tie2-expressing monocytes (TEMs) to CTHRC1-overexpressing tumor tissues. Treatment with a CTHRC1-neutralizing antibody-abrogated Ang-2 expression in the ECs in vitro. Moreover, administration of a CTHRC1-neutralizing antibody to a xenograft mouse model reduced the tumor burden and infiltration of TEMs in the tumor tissues, indicating that blocking the CTHRC1/Ang-2/TEM axis during angiogenesis inhibits tumorigenesis. Collectively, our findings support the hypothesis that CTHRC1 induction of the Ang-2/Tie2 axis mediates the recruitment of TEMs, which are important for tumorigenesis and can be targeted to achieve effective antitumor responses in pancreatic cancers.

Many bone-related diseases such as osteoporosis, rheumatoid arthritis are occurred by excessive bone resorbing activity of osteoclasts. Recently, many studies have been proceeded to find out the new therapeutic materials from natural products of plants. Phlomis umbrosa Turcz, one of the natural products of plants has been known to improve bone health. However, the precise effects and treatment mechanisms of Phlomis umbrosa Turcz about bone diseases has been unknown. So, we examined the effects of Phlomis umbrosa Turcz on expression of receptor activator of nuclear factor-kappaB ligand (RANKL)-induced osteoclast differentiation in bone marrow-derived macrophages (BMMs) and bone resorption. Also, we investigated the treatment mechanisms of Phlomis umbrosa Turcz relating to osteoclast differentiation. Here, we showed that Phlomis umbrosa Turcz significantly suppressed RANKL-induced osteoclast differentiation and bone resportion. Furthermore, Phlomis umbrosa Turcz suppressed the activation of NF-kappaB in bone marrow macrophage treated RANKL and M-CSF. The mRNA expression of c-Fos, nuclear factor of activated T-cells (NFAT)c1, osteoclast-associated receptor (OSCAR), tartrate-resistant acid phosphatase (TRAP) in BMMs was inhibited by Phlomis umbrosa Turcz. Integrin alphanu, beta3 relating to cell adhesion and dendritic cell-specific transmembrane protein (DC-STAMP) relating to the structure of filamentous actin (F-actin) ring and cathepsin K relating to bone resorbing activity are disrupted too. These results suggest that Phlomis umbrosa Turcz will be a good materials to treat bone diseases like osteoporosis.

It is important to identify therapeutic compounds with no adverse effects for use in the chemotherapy of patients with bone-related diseases. The aim of this study was to identify a new compound that inhibits osteoclast differentiation and bone resorption. Herein, we examined the effects of 1',2'-dihydrorotenone on osteoclast differentiation and bone resorption in vitro and in vivo. 1',2'-dihydrorotenone inhibited receptor activator of NF-kappaB ligand (RANKL)-induced osteoclast differentiation of cultured bone marrow macrophages (BMMs) in a dose-dependent manner. However, 1',2'-dihydrorotenone did not exert cytotoxic effect on BMMs. 1',2'-dihydrorotenone suppressed the expression of c-fos and NFATc1 as well as osteoclast-specific genes in BMMs treated with RANKL. Treatment with RANKL inhibited the expression of inhibitors of differentiation/DNA binding (Id)1, 2, and 3; however, in the presence of 1',2'-dihydrorotenone, RANKL did not suppress the expression of Id1, 2, and 3. Furthermore, 1',2'-dihydrorotenone inhibited bone resorption and considerably attenuated the erosion of trabecular bone induced by lipopolysaccharide treatment. Taken together, these results suggest that 1',2'-dihydrorotenone has the potential to be applied in therapies for bone-related diseases.

BACKGROUND: The increasing rate of drug-resistant tuberculosis (TB) is a threat to the public health and TB control. In Korea, about 75~80% of TB patients are treated in private hospitals and the rate has been continuously increasing since 2000. METHODS: On a retrospective basis, we enrolled 170 newly diagnosed with or retreated for multidrug-resistant TB (MDR-TB) in 2004 from 21 private hospitals. We extracted the following demographics and treatment history from patient medical records: initial treatment outcomes, cumulative survival rates, treatment outcomes, and prognostic factors. RESULTS: Of the 170 patients, the majority were male (64.1%), the mean age was 44.5 years old, and mean body-mass-index was 20.2 kg/m2. None of the patients tested positive for HIV. Eleven (6.5%) were confirmed to have extensively drug-resistant TB (XDR-TB) at treatment initiation. Treatment success rates were not different between XDR-TB (36.4%, 4/11) and non-XDR MDR-TB (51.6%, 82/159). Default rate was high, 21.8% (37/170). Far advanced disease on X-ray was a significant negative predictor of treatment success; advanced disease and low BMI were risk factors for all-cause mortality. CONCLUSION: In private hospitals in Korea, the proportion of XDR-TB in MDR-TB was comparable to previous data. The treatment success rate of MDR-/XDR-TB remains poor and the failure rate was quite high. Adequate TB control policies should be strengthened to prevent the further development and spread of MDR-/XDR-TB in Korea.
