Objective: We intended to verify the syndemic effect of psychosocial health conditions on suicidal ideation among men who have sex with men (MSM) in Shanghai, China; design a comprehensive framework for the identification of the MSM with suicidal ideation; and provide suggestion for suicidality intervention among MSM. Method: A cross-sectional study was conducted among 547 MSM in 4 districts in Shanghai. Sociodemographic, psychosocial, and suicidal ideation information of the participants was collected. Logistic regressions were performed to assess the relationship between psychosocial variables and suicidal ideation and to verify the syndemic effect of psychosocial factors. Results: Of the MSM sample, 10.6% reported suicidal thoughts in the past year. In univariate analysis, depression, anxiety, loneliness, impulsivity, involuntary subordination (IS), social support, and risky sex were associated with suicidal ideation. Multivariate analysis found that IS (ORm = 2.92, 95% confidence interval [CI] = 1.55-5.51) and risky sex (ORm = 3.79, 95% CI = 1.44 -9.97) remained significant. The MSM with more than 5 psychosocial health problems were nearly 4 times more likely (adjusted odds ratio = 4.68, 95% CI = 2.23-9.80) to have had suicidal ideation in the past year. Conclusions: The study confirmed the syndemic effect of psychosocial health problems in magnifying the risk of suicidality among MSM. More integrated and holistic approaches in the identification of high-risk groups and intervention of suicidality among MSM are needed. © 2015 American Psychological Association. Source

Capacity is one fundamental problem in wireless Ad hoc networks. Deploying directional antennas to wireless networks can reduce interference among concurrent transmissions and increase spatial reuse, while the technology of multi-channel can separate concurrent transmissions. Therefore, combining these two technologies into one wireless network is capable of great improvement on the network capacity. Recent studies proposed a multi-channel network architecture that equips each wireless node with multiple directional antennas, which is called MC-MDA network. The capacity in MC-MDA network is derived under arbitrary and random placements. However, they only used a simplified directional antenna model. For approaching the more accurate capacity in real scenario, we consider a hybrid antenna model, which takes the effect of side lobe into account. We derive the capacity upper-bounds of MC-MDA networks in arbitrary and random network with the hybrid model to find the effect of side lobe. We show that the network capacity is closely related to the ratio of the radiuses of side lobe to main lobe. The capacity decreases when the ratio increases. Moreover, we compare the network capacity of MC-MDA using the simplified antenna model with our results. Source

The study analyzed the status of diabetes education at community in a developed city. A community with sixteen health clinics was enrolled in the study. Questionnaires were used and qualitative interview applied to four clinics and their physicians in the area. Investigation focused on the plan, educator, program, costs, evaluation, obstacles, and satisfaction in diabetes education. The survey was based on the National Diabetes Education Practice Survey (AADE 2008) and Chinese Diabetes Prevention and Care Guideline (CDA 2004). In the survey community, there were inconsistencies in the diabetes educator training curriculum, education method and evaluation. The frequency of education and the percentage of educated patients with diabetes differed depending on the staff to patient ratio. No dietician enrolled in diabetes education at community. The education courses were mainly developed by clinic with different method. The sessions mainly included basic information of disease, nutrition, treatment and complications, but little emphasis on behavioral supporting. Investment of financial and human resource for diabetes education still is a major challenge at community. The results indicate the areas for improvement of diabetes education at community in China, especially in evaluation and standardization. It is an important and necessary step to promote the effect of diabetes control for China in the future. Source

Diagnostic biomarkers for early detection of renal cell carcinoma (RCC) are in great need. In the present study, we compared the serum protein profiles of patients with small RCC to those of healthy individuals to identify the differentially expressed proteins with potential to serve as biomarkers. Serum samples were collected from 10 patients with small RCC and 10 healthy individuals. The serum protein expression profiles were analyzed by two-dimensional (2-D) gel electrophoresis. Twenty-seven proteins with differences in expression levels between RCC patients and healthy volunteers were identified. Of these, 19 were expressed at different levels and eight were expressed in serum from the RCC group, but not from the control group. Six differentially expressed proteins identified by using mass spectrometry included coagulation factor XIII B, complement C3 and its precursor, misato homolog 1 (isoform CRA_b), hemopexin, and alpha-1-Bglycoprotein. Some of these serum proteins are known regulators of tumor progression in human malignancies. In conclusion, we successfully applied 2-D gel electrophoresis and identified six serum proteins differentially expressed between patients with small RCC and healthy volunteers. These proteins may provide novel biomarkers for early detection and diagnosis of human RCC. © 2010, National Institute of Science Communication and Information Resources (NISCAIR).
