Severe sepsis and septic shock are the main causes of death in critically ill patients. Early detection and appropriate treatment according to guidelines are crucial for achieving favorable outcomes. Endotoxin is considered to be a main element in the pathogenic induction of gram-negative bacterial sepsis. Polymyxin B hemoperfusion can remove endotoxin and is reported to improve clinical outcomes in patients with intra-abdominal septic shock, but its clinical efficacy for pneumonic septic shock remains unclear. Here, we report a case of a 51-year-old man with pneumonic septic shock caused by Pseudomonas aeruginosa, who recovered through polymyxin B hemoperfusion.

Methods: Self-report questionnaires were distributed during October 2017. Results: Based on a multiple regression analysis, the significant factors found to affect the wellness of bus drivers were physical activity (β=.48,p<.001), subjective happiness (β=.25, p=.001), and job stress (β=-.17, p=.025). The total explanatory power of the study variables for wellness was 45.7% (F=33.04, p<.001). Conclusion These findings highlight a need to develop workplace wellness programs to reduce job stress and improve physical activity and subjective happiness among bus drivers.

STATEMENT OF PROBLEM: The role of calcium sulfate in stimulating the growth of gingival soft tissue has been reported in few studies. Such a unique property of calcium sulfate could serve as a trouble-solving broker in compensating for the lack of soft tissues in various oral surgeries. PURPOSE: The purpose of this study was to compare the proliferating activities of human gingival fibroblasts seeded on various bone graft barrier materials of calcium sulfate, collagen, and polytetrafluorethylene (PTFE). MATERIAL AND METHODS: Two calcium sulfates (CAPSET(R) and CalForma(R), Lifecore Biomedical Inc., St. Paul, Minnesota, USA), a resorbable natural collagen (Bio-Gide(R), Geistlich Pharma Ag., Wolhusen, Switzerland), and a non-resorbable PTFE (TefGen-FD(R), Lifecore Biomedical Inc., St. Paul, Minnesota, USA) served as the human gingival fibroblasts'substrates and comprised the four experimental groups, whereas the untreated floors of culture plastics were used in the control group, in this study. Cells were trypsinized, seeded, and incubated for 48 h. The proliferating activities of fibroblasts were determined by XTT and SRB assay and absorbance (optical density, OD) was measured. One-way ANOVA was used to analyze the differences in the mean OD values between the groups of CAPSET, CalForma, Bio-Gide, TefGen, and the control (p<0.05). RESULTS: From the XTT assay, the mean OD value of the control group, the highest, was significantly greater than that of any of the four experimental groups followed by CalForma, CAPSET, TefGen, and Bio-Gide. Further, the mean OD value of CalForma, was significantly greater compared to that of Bio-Gide. From the SRB assay, Calforma showed the highest mean OD value, which was significantly greater than that of any other groups, followed by the control, CAPSET, Bio-Gide, and TefGen. The mean OD values of both the control and CAPSET were significantly greater compared to that of TefGen (p<0.05). CONCLUSION: Assessment of the viability and proliferation of cultured fibroblasts seeded and incubated for 48 h on various barrier-material substrates using XTT and SRB assay showed that calcium sulfate CalForma(R) promotes the proliferating activity of human gingival fibroblasts.

PURPOSE: The purpose of this study was to evaluate the effectiveness of a health promotion program utilizing action planning strategy for young adults. METHODS: A non-equivalent control group pre-post-test design was used. One hundred three university students participated in the study. Participants in the experimental group (n=51) were provided the health promotion program utilizing action planning strategy for five weeks. The program consisted of weekly sessions that included action planning and group feedback. The control group (n=52) was provided with health information every week for 5 weeks. Program outcomes, including self-efficacy, physical activity health behaviors, total exercise time per week, daily cigarette consumption, frequency of alcohol drinking per month, nutritional health behaviors, and subjective health status, were assessed at baseline and at follow-up after 5 weeks. RESULTS: The participants in the experimental group demonstrated significant increases in self-efficacy, physical activity health behaviors, weekly exercise time, and nutritional health behaviors and significant decreases in daily cigarette consumption than those in the control group. CONCLUSION: The health promotion program utilizing action planning strategy is a brief and effective intervention to promote health behaviors among young adults. Further investigation is warranted to assess the program's effectiveness among other age groups and populations at high risk for chronic illness.

Mitral ring motion and indices of left ventricular diastolic filling were measured by M-mode and Doppler echocardiography in apical 4 chamber view in 11 dilated cardiomyopathy patients and 9 normal subjects without clinical evidence of heart disease. The mean age of patients was 52 years and average heart rate was 76 beats/min. The parameters of mitral annulus motion include earley relaxation amplitude(ER), late atrial contraction amplitude(AC) and A2-peak excursion(A2-PE). Transmitral flow velocity parameters include peak flow velocity of early diastolic flow velocity(PFVE), peak flow velocity of late atrial contraction(PFVA), the ratio between early and late peak flow velocity(PFVE/PFVA), Acceleration rate of early diastolic peak flow(AR), deceleration rate of early diastolic peak flow(DR), time velocity integral of early diastolic flow velocity(TVIE), time velocity integral of late atrial contraction flow velocity(TVIA) and ratio between early diastolic and late atrial flow velocity integral(TVIE/TVIA). In patients with dilated cardiomyopathy, ER(4.5+/-2.3mm) and AC(2.3+/-1.6mm) were significantly decreased than normal(10.7+/-2.6mm, 6.6+/-1.6mm, p<0.01, p<0.01, respectively), whereas ER/AC(1.7+/-0.7) was not significantly different than normal subjects(1.6+/-0.5). A2-PE(100+/-80 msec) was significantly delayed in dilated cardiomyopathy patients than normal subjects(35+/-25 msec, p<0.01). In analysis of transmitral flow velocities, PFVE, PFVA and PFVE/PFVA, etc were not significantly different compared to normal subjects in patients with dilated cardiomyopathy. Mitral ring motion amplitude was decreased and A2-peak excursion time interval(A2-PE) was delayed in patients with dilated cardiomyopathy, but transmitral flow velocities were not significantly different from normal subjects in patients with dilated cardiomyopathy. These results reflect the facts that early diastolic relaxation amplitude is decreased by the change of compliance of LV and late atrial contractin amplitude is decreased by decrease of atrial contractility and increased stiffness of LA and LV. Despite of decreased mitral ring motion, transmitral flow velocity is not significantly different compared to normal subjects in patients with dilated cardiomyopathy. From these evidences, not only transmitral flow velocity affected by multiple factors but also mitral ring motion affected by LA and LV function are considered in assessment of LV diastolic dysfuction.

Spinal neurenteric cyst results from the persistence of an abnormal communication between endodermal and neuroectodermal layer. It is a rare malformation that lead to spinal cord compression. The patient is a 22-month-old boy with sudden, progressive left side motor weakness. Preoperative magnetic resonance image revealed intradural extramedullary cyst in C4-C5 level that compressed the spinal cord on the left side. After the resection of the cyst, motor weakness of the left side was partially improved, and his motor power was completely recovered after rehabilitation. Histologic examination revealed a ciliated columnar epithelial neurenteric cyst. The pre- and postoperative clinical features of the case of neurenteric cyst is described with the review of literature.

PURPOSE: To determine the usefulness of compression standard JPEG2000 for compression of mammographic images. MATERIALS AND METHODS: Image of a mammographic phantom was compressed using JPEG2000 at ratios of 10:1, 20:1, 30:1, 40:1, 50:1 and 60:1. The sizes of the images were compared, and scores were recorded by counting the numbers of fibers, groups of specks and masses seen in each phantom image. More than four fibers, three groups of specks and three masses and a total score of 10 were considered acceptable. RESULTS: The size of a DICOM image was 17,042 KB, a TIFF image was 8,324 KB, the original JPEG image was 1,506 KB and the most compressed image (50:1) above an acceptable total score of 10 was 43 KB. In each category, the compression image of fiber was acceptable up to compression ratio of 50:1 (score of 5), groups of specks was acceptable up to 60:1 (score of 3) and mass was acceptable up to 50:1 (score of 3.5). The total score, which was acquired by adding up the individual scores of all three categories, for a compression ratio of 50:1 was 12 and was acceptable, but the total score for 60:1 was 8 and was not acceptable. CONCLUSION: The compression standard JPEG2000 is an efficient means for compressing mammographic images at high ratios without compromising diagnostic value.
