PURPOSE: This study aimed to investigate nutritional risk, physical activity, and quality of life (QoL) and the interaction of these factors in colorectal cancer patients. METHODS: Participants were colorectal cancer patients receiving follow-up treatment at the colorectal cancer outpatient clinic of Severance Hospital in Seoul. Participants were recruited from October 25 to November 30, 2010. The survey questionnaire consisted of Nutritional Risk Score (NRS), International Physical Activity Questionnaire (IPAQ) and Functional Assessment of Cancer Therapy - scales for Colorectal Cancer (FACT-C). RESULTS: NRSs were significantly higher in patients with low BMI (F=18.63, p<.001) and those who were underwent colorectal surgery within 1 month (F=5.96, p<.001). Physical activity level of the participants was 28.96METs. Lower nutritional risk was associated with a higher QoL (r= - .34, p<.001). In a multiple regression analysis, the predictors of QoL were the age, economic status, and nutritional risk of the patient (R2=40.0%). CONCLUSIONS: Targeted tailored nursing interventions are needed to assess nutritional risks in order to improve colorectal cancer patients' QoL.

Objective To investigate the characteristics and distribution of human eehinococcosis in Hobukesar Mongolian Autonomous County (HMAC) in Xinjiang. Methods Using cluster sampling methods, the 2 counties (Tiebukenwusa and Narenhebuke) in HMAC were chosen as focusing areas for investigation. A survey of human echinococcosis including questionnaire, serological test and abdominal ultrasonic scan was carried out. Results The prevalence of human echinococcosis was 9.0% (64/712) by ultrasound and surgical history, including 8.7% (62/712) for cystic eehinococcosis(CE), 0.3%(2/712) for alveolar echinococcosis(AE) and 15.6%(111/712) for total of serological positives in HMAC. CE prevalence rate of different occupations, age, family slaughtering livestock and drinking water source had significant differences(P<0.05). Herdsmen as the highest risk group showed a CE prevalence of the 13.4% (27/201) in comparison with other occupations. The ages between 20 to<40 year-old were at the highest risk stage with 12.8% incidence. But CE prevalence rate of different gender, ethnic and education groups had not significant differences(P>0.05). Conclusions HMAC could be considered as a high endemic human CE region in Xinjiang. The current study reported the main risk factors may include occupations, age difference and drinking water source.

OBJECTIVETo evaluate the spiral CT and its reconstruction techniques in diagnosis and localization of gastrointestinal stromal tumor originated in the small intestine.
METHODSThe data of spiral CT scan and MPR, STS-MIP of 24 patients with gastrointestinal stromal tumor in the small intestine confirmed pathologically were analyzed retrospectrvely.
RESULTSOf 24 cases, 1 had multiple tumor, while the other 23 had single one. Seventeen of these tumors were benign and 7 malignant, with 2 in the duodenum, 12 in the jejunum and 10 in the ileum. The range of tumor diameters was from 2.5 to 12 cm. The main clinical characters of the tumors on the CT image: (1) The tumor of 15 cases located outside of the enteric cavity, 7 inside of the enteric cavity or presented as thicken bowel wall and 2 showed as niche sign. (2) The tumor shape of 19 cases were round-like, and 5 lobulated or irregular. (3) The tumor density of 12 cases was homegeneous, 7 heterogeneous and 5 map-like in the center. (4) The tumor enhancement style in 19 cases were homegeneous in dynamic enhanced scan, and 16 were slightly or mildly heterogeneous in the artery phase but apparently enhanced in the venous and equilibrium phase, with 5 showed as fast-in fast-out enhanced mode. Of those, one showed obvious enhancement in artery phase, while 2 did not. (5) The tumor of 2 cases had no clear margin and had invaded the surrounding tissue. (6) The arteries supplying tumors in 20 cases were demonstrated by multiple planar reconstruction (MPR), sliding thin slab-maximum intensity projection (STS-MIP). The accuracy of diagnosis and localization of gastrointestinal stromal tumor in the small intestine by spiral CT scan combined with MPR, STS-MIP were 91.7% (22/24) and 95.8% (23/24), respectively.
CONCLUSIONSpiral CT and its reconstruction techniques (MPR, STS-MIP) can play an important role in the differential diagnosis and localization of gastrointestinal stromal tumor originated in the small intestine.

OBJECTIVETo compare the efficacy of nuclear microarray combined with fluorescence in situ hybridization (FISH) and immunohistochemistry in detecting ALK gene translocation and ALK fusion protein in anaplastic large cell lymphoma (ALCL).
METHODSALK gene translocation and ALK fusion protein in 17 paraffin-embedded ALCL specimens were detected using nuclear microarray combined with FISH and immunohistochemical straining, respectively.
RESULTSThe expression of ALK fusion protein was detected immunohistochemically with ALK antibody in 8 of the 17 specimens of systemic ALCL, including 4 with both nuclear and cytoplasmic positivity and 4 with only cytoplasmic positivity. Dual-color FISH identified 6 positive specimens, including the 4 specimens with both nuclear and cytoplasmic positivity as identified immunohistochemically, and 2 with immunohistochemical cytoplasmic positivity. FISH yielded negative results for the 2 specimens with immunohistochemical cytoplasmic positivity.
CONCLUSIONNuclear microarray combined with FISH eliminated the cytoplasmic interference of the results of conventional FISH and provides a high-throughput platform for clinical detection with greater specificity than immunohistochemistry.

OBJECTIVES: Controlling blood pressure is a key step in reducing cardiovascular mortality in older adults. Gender differences in patients' attitudes after disease diagnosis and their management of the disease have been identified. However, it is unclear whether gender differences exist in hypertension management among older adults. We hypothesized that gender differences would exist among factors associated with hypertension diagnosis and control among community-dwelling, older adults. METHODS: This cross-sectional study analyzed data from 653 Koreans aged > or =60 years who participated in the Korean Social Life, Health, and Aging Project. Multiple logistic regression was used to compare several variables between undiagnosed and diagnosed hypertension, and between uncontrolled and controlled hypertension. RESULTS: Diabetes was more prevalent in men and women who had uncontrolled hypertension than those with controlled hypertension or undiagnosed hypertension. High body mass index was significantly associated with uncontrolled hypertension only in men. Multiple logistic regression analysis indicated that in women, awareness of one's blood pressure level (odds ratio [OR], 2.86; p=0.003) and the number of blood pressure checkups over the previous year (OR, 1.06; p=0.011) might influence the likelihood of being diagnosed with hypertension. More highly educated women were more likely to have controlled hypertension than non-educated women (OR, 5.23; p=0.013). CONCLUSIONS: This study suggests that gender differences exist among factors associated with hypertension diagnosis and control in the study population of community-dwelling, older adults. Education-based health promotion strategies for hypertension control might be more effective in elderly women than in elderly men. Gender-specific approaches may be required to effectively control hypertension among older adults.
