<P>Patients undergoing treatment for cancer have reported a variety of work-related problems. The aim of this study was to investigate the impact of a cancer diagnosis on employment status, and to identify relevant associated factors. This prospective cohort study was conducted at the National Cancer Center in Korea. Male patients newly diagnosed with stomach, liver, or colorectal cancers were recruited. Patients were interviewed and asked to complete an employment questionnaire every 3 months for 24 months. Clinical, sociodemographic and work-related factors were assessed. There were 305 male patients who had a primary diagnosis of cancer and underwent appropriate treatment. Of the 305 male patients who were employed at the time of diagnosis, 53% lost their job, and of these 23% later reemployed. In a multivariate Cox regression analysis, job loss was significantly associated with years of education, job characteristics and disease stage. Reemployment was significantly associated with disease stage and cancer site. Change of employment was common among cancer patients in Korea. With an understanding of the factors involved, it should be possible to reduce unnecessary work cessation, and increase the rate of employment of cancer survivors.

Medical mushroom, Phellinus linteus and Phellinus baumii called as “Sanghwang” have cultivated in Korea. PL has been studied extensively for its extraordinary capacity of suppressing cancer or enhancing body immunity. The mycelial materials of PL have mainly been used as research samples worldwide because fruiting bodies was difficult to be artificially cultivated. Alternatively, P. baumii (variety, ‘Jangsu’) have been cultivated in Korea. However, fruiting body morphology of P. baumii is clearly different to that of PL. Generally, Phellinus spp. including P. linteus slowly grow on artificial medium such as Potato Dextrose Agar (PDA). In contrast, P. baumii strains were rapidly grown on the artificial media when compared to other Phellinus spp. and thus it was considerable that its mycelial growing ability can be acted as a factor for producing fruiting bodies. This study aimed to find Phellinus isolates having high mycelial growth rate. Five Phellinus isolates that show rapid growth rate on YGM medium were selected from 36 Phellinus isolates collected in Korea. They were identified on nucleotide sequences of rDNA-ITS region. Phellinus linteus strain and Phellinus spp. showing mycelial growth rate comparing to P. baumii were characterized on cultural and bioactive characteristics (antioxidant activity and immune activation).

Background: This study aimed to investigate the effects of shift work on abdominal obesity among young and middle-aged female nurses during a 5-year retrospective study. Methods: This retrospective study included female nurses (20–39 years old) who worked at a university hospital in Korea and had available health screening results from 2010–2015. Among 2,611 employees, 934 healthy 20–39-year-old female nurses were identified, and data regarding their demographic information (age and date of employment), waist circumferences (WC), and lifestyle factors (alcohol and exercise) were obtained. Abdominal obesity was defined as a WC of ≥80 cm, based on the World Health Organization’s Asia-West Pacific standard in 2000. The mean WC change from baseline was analyzed using the paired t test, and the association between shift work and abdominal obesity was analyzed using the generalized estimating equation. Results: Compared to all day workers (both age groups), the 20–29-year-old nurses did not exhibit significant changes in WC at each follow-up. However, among the 30–39-year-old nurses, shift workers exhibited a significant change in WC (vs. baseline) during years 4 and 5, compared to day workers. After adjusting for effective confounders and stratifying the participants according to age, the 20–29-year-old nurses exhibited an odds ratio of 3.21 (95 % confidence interval: 1.29–7.98) for shift work-associated obesity, although the odds ratio for the 30–39-year-old nurses was not statistically significant. Conclusion: In the study population, shift work was associated with a significant change in mean WC among 30–39-yearold nurses, and the shift work-associated risk of abdominal obesity was significant among 20–29-year-old nurses. These results indicate that shift work may influence abdominal obesity differently in 20–29-year-old and 30–39-year-old female nurses.
