Background: Management of healthcare workers’ job stress is critical for improve- ment of health care service. There are many studies concerning healthcare workers’
job stress, but research about endoscopy unit workers is minimal. The aim of this study is to estimate the job stress and job satisfaction among endoscopy unit workers for improvement of medical services.
Methods: We surveyed doctors, nurses and nurse assistants at the endoscopy unit of three medical centers in Korea (n=60). The questionnaire included demographic char- acteristics, job stress questionnaire (KOSS; Korean Occupational Stress Scale) and job satisfaction questionnaire. Data was analyzed by IBM SPSS 20.
Results: Average total job stress score of endoscopy unit workers was signifi cantly lower compared to average Korean occupational stress (Fig 1). Job stress and job sat- isfaction were signifi cantly different among job positions (p=0.006 and p<0.001 for each), and nurse group showed signifi cant higher stress level to professors or fellows (Fig 2). Correlation analysis showed job stress and job satisfaction are signifi cantly correlated with each other (r=-0.585, p<0.001).
Conclusions: Job stress score was signifi cantly different among job positions, and ‘in- suffi cient job control’ and ‘organizational system’ were the troublesome stress factors.
Possible solutions could be open discussion with nurses for decision making and fair personnel management policy. In addition, we could fi nd out the unique difference of stress quality of endoscopy unit workers compared to Korean average occupations.
Regular examination of job stress is essential for quality assurance and quality im- provement of healthcare services in endoscopy unit.

Background: Capsule endoscopy is essential examination for diagnosis of small bowel bleeding. But diagnostic yield of capsule endoscopy is 38% to 83% in obscure overt GI bleeding. For an accurate diagnosis of cause of obscure GI bleeding, the time to per- form capsule endoscopy is the most important factor. This study is to investigate the diagnostic yield, rate of therapeutic intervention and prognosis according to timing of capsule endoscopy in the obscure overt GI bleeding patients.
Methods: We conducted a single center, retrospective study from April 2008 to April 2013. Patients who were negative result of initial upper endoscopy and colonoscopy were enrolled. We divided the patients into two groups: those who had performed capsule endoscopy within 2 days of last overt GI bleeding (=2-day group) and after 2 days of last overt GI bleeding(>2-day group). We compared the diagnostic yield, rate of therapeutic intervention, hospital day and rate of re-bleeding between the two groups. We defi ned positive fi nding as active bleeding or any cause of small bowel bleeding.
Results: 102 capsule endoscopies were performed to evaluate obscure overt GI bleed- ing during the period. Among them, 81 patients were included and 21 patients who lacked of medical records were excluded. Diagnostic yield was 75% in =2-day group and 45% in >2-day group (p=0.022). Therapeutic intervention was done in 45% of the=2-day group and 14% of >2-day group (p=0.006). The average day of hospital stay was 5.7 days in =2-day group and 7.9 days in >2-day group (p=0.021). Re-bleed- ing rate between the =2-day group and >2-day group was not signifi cantly different.
Conclusions: Early capsule endoscopic examination within 2 days of last overt GI bleeding may improve the diagnostic yield and rate of therapeutic intervention and length of hospital day.

Background: Hypothalamus-pituitary-adrenal-axis activity is suggested to be involved in the pathophysiology of the metabolic syndrome, which may be induced by feeding high fat diet. The purpose of this study is to elucidate whether high fat food has an effect on the chronic variable stress induced behavioral and neurochemical changes in male and female rats.
Methods: Fifty-two male and fi fty four female rats, aging about eight weeks, were divided into 4 groups respectively : ① control (reg-con), ② no stress with high fat diet feeding (fat-con), ③ chronic variable stress with regular food (reg-str), ④ chronic variable stress with high fat diet (fat-str). The weight of body, adrenal gland and fat, and the levels of the plasma adrenocorticotropic hormone(ACTH) and corticosterone were measured. Plasma levels of pro- and anti-infl ammatory cytokines (TGF(trans- forming growth factor)-ß, IL(interleukin)-12, IL-2 and interferon-γ) were also investi- gated.
Results: All stress groups showed signifi cantly increase in the relative adrenal gland weight compared to the control group. There was signifi cant increase in the plasma corticosterone concentration in reg-str group in both male and female rats. However, there were no signifi cant differences in the levels of the plasma ACTH concentration in all groups. In the open fi eld test, only female rats undergone stress (reg-str & fat-str) were shown the increased activity. In Western blotting assays, IL-12 and interferon-γ, were signifi cantly increased in high fat diet group (fat-con & fat-str).
Conclusions: These results suggest that there is a different behavioral response under the non-adaptable chronic stress between male and female rats. In addition, the high fat diet possibly contributes to the reduction of corticosterone, but might be induced the production of the pro-infl ammatory cytokines.
