However, the information on the type of anxiety disorder and its prevalence in persons with T2DM is limited. Aims To assess the prevalence and correlates of anxiety disorder in people with type 2 diabetes in different countries. Methods People aged 18-65 years with diabetes and treated in outpatient settings were recruited in 15 countries and underwent a psychiatric interview with the Mini-International Neuropsychiatric Interview. Demographic and medical record data were collected. Results A total of 3170 people with type 2 diabetes (56.2% women;with mean (SD) duration of diabetes 10.01 (7.0) years) participated. The overall prevalence of anxiety disorders in type 2 diabetic persons was 18%;however, 2.8% of the study population had more than one type of anxiety disorder. The most prevalent anxiety disorders were generalised anxiety disorder (8.1%) and panic disorder (5.1%). Female gender, presence of diabetic complications, longer duration of diabetes and poorer glycaemic control (HbA1c levels) were significantly associated with comorbid anxiety disorder. A higher prevalence of anxiety disorders was observed in Ukraine, Saudi Arabia and Argentina with a lower prevalence in Bangladesh and India. Conclusions Our international study shows that people with type 2 diabetes have a high prevalence of anxiety disorders, especially women, those with diabetic complications, those with a longer duration of diabetes and poorer glycaemic control. Early identification and appropriate timely care of psychiatric problems of people with type 2 diabetes is warranted.展开更多

OBJECTIVE: To observe the changes of anxiety related behaviors in rats after single administration of different doses of MDMA. DESIGN: A randomized control study. SETTING: Laboratory of Psychopharmacology of the Mental Health Center, West China Hospital of Sichuan University. MATERIALS: Thirty male adult Wistar rats, weighing (251.3±18.34) g, were used. MDMA were obtained from the National Institute for the Control of Pharmaceutical and Biological Products, and dissolved in saline. All the doses of the drug were administered in a volume of 1 mg/kg. METHODS: The experiment was carried out in the Laboratory of Psychopharmacology of the Mental Health Center, West China Hospital of Sichuan University in July 2003. ①The rats were randomly divided into control group (n=6) and experimental group (n=24), and then those in the latter were randomly assigned into four subgroups of MDMA 3, 5, 10 and 20 mg/kg groups, with 6 rats in each, which were administrated by single intraperitoneal injection of MDMA 3, 5, 10 and 20 mg/kg respectively, and those in the control group were administrated by single intraperitoneal injection of saline of the same volume. ② The open field test, elevated plus-maze test and social interaction test were performed immediately after administration. For the open field test, the apparatus was situated in a darkened room, illuminated by a single 60 W white light bulb located approximately 60 cm above the center of the open field. Before administration, all the rats were placed into the open field to be familiar with the open field for 5 minutes. They were observed for 45 minutes after administration. The locomotion (number of squares the rat passes), rearing response, time spent in central squares and defecation were observed, 1 minute for each time for a total of 9 times. For the elevated plus-maze test, the maze was situated in a quiet darkened room, illuminated by a single 60 W white light bulb located approximately 50 cm above the center of the maze. Arm entries were only counted when all the four paws had entered either a closed or an open arm within 5 minutes, and the time spent in the arms were observed. For the social interaction test, the matched rats were put into the arena head-to-head in opposite direction, and aggressive-type behaviors, avoidance, passive and exploration were observed. ③ The one-way analysis of variance was performed with the SPSS 10.0 software. MAIN OUTCOME MEASURES: The results of open field test, elevated plus-maze test and social interaction test were observed. RESULTS: All the 30 rats were involved in the analysis of results. ① Results of open field test: After single administration of MDMA of 5, 10 and 20 mg/kg, the dose-dependent locomotors (number of squares the rat passes) in the experimental groups were obviously higher than those in the control group [(21.67±17.55), (34.44±19.47), (33.48±23.34), (7.31±6.02) s; P < 0.05], and the rearing responses were markedly lower than those in the control group [(0.70±1.71), (0.96±1.68), (0.39±0.88), (1.37±1.59) s, P < 0.05]. ② Results of the elevated plus-maze test: After acute administration of MDMA, there were no differences between the MDMA subgroups and saline group in the number of open-arms entries, the open-arms time, the percent of number of open arm entries/total arm entries, and the percent of time spent on the open arms/total time (P > 0.05). ③ Results of the social international test: After acute administration of MDMA, there were no differences between the MDMA subgroups and saline group in the aggressive-type behaviors, avoidance, passive, exploration and total time of interaction (P > 0.05) CONCLUSION: The acute administration of MDMA has no obvious influence on the anxiety-related behaviors of rats.展开更多
