Background: Shift work is associated with obesity and metabolic syndrome. However, this association in the normal-weight population remains unclear. This study aimed to investigate whether shift work is associated with normal-weight obesity (NWO). Methods: From the nationally representative Korea National Health and Nutrition Examination Survey (KNHANES) dataset (2008 to 2011), 3,800 full-time workers aged ≥19 years with a body mass index (BMI) ≤25 kg/m2 were analysed. We defined NWO as BMI ≤25 kg/m2 and body fat percentage ≥25% in men and ≥37% in women. Working patterns were classified into “daytime,” “other than daytime,” and “shift.” Multivariable logistic regression analysis was performed to evaluate the relationship between shift work and NWO. Results: Shift work was associated with higher odds of NWO than daytime work (adjusted odds ratio [aOR], 1.47; 95% confidence interval [CI], 1.04 to 2.09) and night/evening work (aOR, 1.87; 95% CI, 1.11 to 3.14) after adjustment for type of work, working hours, age, sex, BMI, 25-hydroxyvitamin D levels, homeostatic model assessment for insulin resistance, and other sociodemographic factors. In subgroup analyses, the association between shift work and NWO was more robust in those aged ≥60 years and those working ≥56 hours/week. Conclusion Shift work was associated with NWO in community-dwelling Korean adults, independent of age, sex, BMI, and other covariates.

BACKGROUND/AIMS: Little information is available on whether the speed of eating differs between individuals with and without dyspepsia, mainly because controlled studies are usually not feasible. METHODS: A survey was applied to 89 individuals with relatively controlled eating patterns, using questionnaires that assessed eating time and functional dyspepsia (FD) based on the Rome III criteria. RESULTS: The prevalence of FD was 12% (11 of 89 participants), and 7% (6 of 89) were diagnosed with gastroesophageal reflux disease (GERD). The proportion of individuals reporting that they ate their meals rapidly was higher for those with FD than for those without FD or GERD (control) (46% vs 17%, p=0.043), as was the reported eating speed (7.1+/-1.5 vs 5.8+/-2.0 [mean+/-SD], p=0.045; visual analog scale on which a higher score indicated faster eating). However, the measured eating time did not differ significantly between FD and controls (11.0+/-2.8 vs 12.8+/-3.3 minutes, p=0.098). The proportion of individuals who ate their meals within 13 minutes was significantly higher for those with FD than for controls (91% vs 51%, p=0.020). CONCLUSIONS: The results of this study suggest that eating speed affects dyspepsia. Further studies are warranted.

BACKGROUND AND OBJECTIVES: The efficiency of second harmonic generation at 532 nm is high when a pulsed Nd : YAG laseris used as a pump source of fundamental waves. The pulse durations of 532 nm-irradiation can be varied from 10 ns to 1000 ns by changing the pumping method. The purpose of this study was to compare the macroscopic and micropscopic changes in the muscle and skin after irradiation by 532 nm Flash lamp pumped solid state (FPSS) laser and Diode pumped solid state (DPSS) laser, whose pulse durations are 600 ns and 100 ns, respectively. MATERIALS AND METHOD: Two experiments were conducted on the muscle and skin of guinea pig. First, the guinea pig muscle and skin were irradiated by the 532 nm FPSS and DPSS lasers with various intensities and time duration. Macroscopic examinations were performed on the muscle lesions and immediate histopathologic examinations on the skin were carried out. RESULTS: The volume of vaporization and necrosis of the guinea pig muscle by the FPSS laser was larger than that by the DPSS laser. The vaporization and necrosis reaction of skin by the FPSS was significantly stronger than that by the DPSS laser. CONCLUSION: It appears that the DPSS laser system would be superior over the FPSS laser system in providing more accurate and precise surgery with less intense injury on the surrounding tissue.

Neurenteric cysts are developmental cysts derived from embryonic endodermal layers. Fewer than 100 have been reported in which there were no associated bone or soft-tissue malformations and only six among those cases showed intramedullary location in the literatures. The authors report a 16-year-old young man with a thoracic intramedullary neurenteric cyst which presented with symptoms of axillary pain and paraparesis. The magnetic resonance imaging showed intramedullary mass extended from level of T3 to T7. There was no associated bone or soft-tissue anomaly. This cyst was partially excised and marupialized into subarachnoid space. The pathological findings were compatible with neurenteric cyst. Nine months later, the cyst recurred and at second operation, cyst wall was removed completely.

OBJECTIVES: The aim of this study was to investigate whether a medium to high degree of total physical activity and indoor physical activity were associated with reduced all-cause and cardiovascular mortality among elderly Korean women. METHODS: A prospective cohort study was done to evaluate the association between physical activity and mortality. The cohort was made up of elderly (> or =65 years of age) subjects. Baseline information was collected with a self-administered questionnaire and linked to death certificates retrieved from a database. Cox proportional hazard models were used to estimate the hazard ratios (HRs) with 95% confidence interval (CI) levels. RESULTS: Women who did not suffer from stroke, cancer, or ischemic heart disease were followed for a median of 8 years (n=5079). A total of 1798 all-cause deaths were recorded, of which 607 (33.8%) were due to cardiovascular disease. The group with the highest level of total physical activity and indoor physical activity was significantly associated to a reduced all-cause mortality (HR, 0.60; 95% CI, 0.51 to 0.71 and HR, 0.58; 95% CI, 0.50 to 0.67, respectively) compared to the group with the lowest level of total physical activity and indoor physical activity. Additionally, the group with the highest level of total physical activity and indoor physical activity was significantly associated to a lower cardiovascular disease mortality (HR, 0.53; 95% CI, 0.40 to 0.71 and HR, 0.51; 95% CI, 0.39 to 0.67, respectively) compared to the group with the lowest level of total physical activity and indoor physical activity. CONCLUSIONS: Our study showed that regular indoor physical activity among elderly Korean women has healthy benefits.
