Background: Suicide is a leading cause of death worldwide. This is the first study in Bangladesh to find out the psychiatric morbidity profile and suicidal behavior. The study was aimed to delineate the types of suicidal behavior and the psychiatric morbidity profile, and sociodemographic status of patients. Methods: A descriptive cross-sectional study was done in Depatrment of Psychiatry, Cumilla Medical College, Cumilla from October 2015 to March 2017. A total 120 patient aged 9 to 40 years who fulfilled the enrolment criteria included in the study. The Composite International Diagnostic Interview (CIDI) module was used to assess the suicidal behavior. DSM-5 was used to diagnose the psychiatric disorders. Semi structural questionnaire were used for collecting information about the risk factors for psychiatric morbidity and sociodemographic information. Result: Of 120 suicidal behavior patients' psychiatric disorders was 65%. Among suicidal behavior patients neurotic disorders was 19%, psychotic disorders was 15%, personality disorders was 39% and others disorder was 27%. Among 78 psychiatric patients borderline personality disorder was 25.64%, adjustment disorders were 15.38%, mood disorders were 11.53%, psychotic disorder was 7.69%, multiple personality disorder and oppositional defiant disorder were 6.42%, hystrionic personality disorder and substance use disorder were 3.84%, antisocial personality disorder, conduct disorder and anxiety disorder were 2.57%, and composite disorder was 11.53%. Among suicidal behavior in psychiatric patients suicidal ideation was 54, suicidal plan was 13, suicidal attempt was 45, ideators only proceeded to plan was 17, ideation to attempt was 59. Among suicidal behavior in total 120 participants suicidal ideation was 84, suicidal plan was 19, suicidal attempt was 56, ideators only proceeded to plan was 26, ideation to attempt was 76, planned attempt was 14 and impulsive attempt was 62. Most of the suicidal behavior participants were female (77.5%) and age group of <24 years (60%). Conclusions: Psychiatric disorders are important risk factors for the onset and persistence of suicidal behaviour, with this risk being the greatest in childhood, and early adult.

Background: Minimal Hepatic Encephalopathy, the mildest from of Hepatic Encephalopathy is characterized by subtle motor and cognitive deficits and impairs health related quality of life. Though the prevalence of Minimal Hepatic Encephalopathy in cirrhotic patient is high but awareness regarding MHE is yet not satisfactory. Moreover diagnosis of MHE, the cut off normative value for psychometric test is yet not established in Bangladesh. This is the first study in Bangladesh to find out the normative value for psychometric test and see the prevalence of Minimal Hepatic Encephalopathy in cirrhotic patient. Methods: Cross sectional study done in Department of Hepatology, BSMMU, Dhaka from July 2012 to June 2014. Total 150 patient of which 50 patient with cirrhosis and remaining 100 healthy individual were included in the study. By doing number connection test, Serial dotting test and line tracing test in healthy individual, first normative values for psychometric test was detected then these test was done on cirrhotic patient, whose 2 psychometric test result among 3 above normal value were enrolled as a case of Minimal Hepatic Encephalopathy. None of the patient previously diagnosed as any type of Hepatic Encephalopathy. Results: Cut off normative value for NCT, SDT, LTT is 52 seconds, 52 seconds and 84 seconds respectively (Mean+2SD). Prevalence of Minimal Hepatic Encephalopathy in this study was 66% and it is more prevalent in advanced cirrhosis. Conclusion: MHE is frequent in patient with liver cirrhosis, manifested even in patient with child pugh A liver cirrhosis. Every attention should be given to detect Minimal Hepatic Encephalopathy in patient with cirrhosis of liver well before the development of overt Hepatic Encephalopathy. [ABSTRACT FROM AUTHOR]

A new low-cost smaller unit-cell planar electromagnetic bandgap (EBG) structure operating at the lower GHz frequencies (below 6 GHz) is proposed. EBG structures based on this new geometry are designed on a number of commonly available substrates. Characteristics of such structures, such as bandgap and reflection phase profile are analyzed. A simple empirical model is proposed to predict the surface wave stopband frequency of the proposed EBG structure. Finally, a low-profile dipole antenna is designed and tested for operation on the EBG structure. [ABSTRACT FROM AUTHOR]
