Suicidal Ideation, Suicidal Plan and Suicidal Attempts Among Those with Major Depressive Disorder

Abstract Introduction: The aims of the study were to identify the prevalence and sociodemographic and clinical correlates of suicidal behaviours using data from a cross-sectional survey among those with major depressive disorder (MDD) in Singapore. Materials and Methods: The Singapore Mental Health Study (SMHS) was a cross-sectional epidemiological study that surveyed Singapore residents (Singapore citizens and permanent residents) aged 18 years and above. The assessment of mental disorders was established using version 3.0 of the Composite International Diagnostic Interview (CIDI 3.0). For the purposes of this study, suicidal behaviour was assessed by questions which were asked to respondents who answered positively to the screening questions in the CIDI 3.0 "Depression" module. Results: The prevalence of suicidal ideation, plan and attempt among those with lifetime MDD was 43.6%, 13.7% and 12.3%, respectively. We found that suicidal ideation, plan and attempt were signifi cantly associated with ethnicity, education and income. The rate of those who had sought some professional help was higher among those with suicidal plan (71.7%) and attempt (72.3%) as compared to those with suicidal ideation (48.7%) and those with MDD but no suicidal behaviour (29%). Conclusion: Individuals with MDD and suicidal behaviour do differ from their non-suicidal counterparts as they have a different sociodemographic and clinical profi le. There is a need for more research and a better understanding of this population which in turn could lead to the development and implementation of relevant interventions

A Crossed Screw Patellar Reconstruction Technique for the Treatment of the Severely Deficient Scaphoid Shaped Patella in Total Knee Arthroplasty

One of the contraindications to patella resurfacing in total knee arthroplasty is a thin and severely eroded ‘deficient’ patella. However, such patients often present with severe patellofemoral joint arthritis, patellar lateral subluxation, and patella maltracking, which can only be treated effectively with resurfacing. While various treatments have been proposed, options remain limited.Here we introduce a method of patella reconstruction using four 2.7-mm titanium cortical screws crossing each other into the inner shell of the patella. This provides a scaffold onto which bone cement and any standard polyethylene patellar component can be fixed. Postoperatively, the patient had no anterior knee pain, no patella maltracking, and no component loosening.Advantages of this technique include minimization of extensor disruption, low costs, easy accessibility, reproducibility, and improved mechanical strength

Socio-demographic Correlates of Positive Mental Health and Differences by Depression and Anxiety in an Asian Community Sample

Abstract Introduction: Positive Mental Health (PMH) instrument is a self-administered multidimensional measure that is validated in the adult multi-ethnic Asian population in Singapore and comprises General Coping (GC), Emotional Support (ES), Spirituality, Interpersonal Skills (IS), Personal Growth and Autonomy (PGA) and Global Affect (GA) domains. This paper aimed to (i) examine socio-demographic differences and identify correlates for the total PMH and domain-specifi c scores in the sample, and (ii) compare the PMH total score for respondents with and without depression or anxiety. Materials and Methods: Singapore residents aged 21 to 65 years, of Chinese, Malay or Indian ethnicity and residing in households across Singapore (n = 404) completed the 47-item PMH instrument in an anonymous survey. Socio-demographic information was obtained during the survey and respondents also completed the Patient Health Questionnaire (PHQ)-8 and Generalised Anxiety Disorder (GAD)-7 scale to establish depression and anxiety. Descriptive analyses were conducted to examine for differences in PMH scores by socio-demographic groups and between those with and without depression and anxiety. Results: The total PMH score was signifi cantly different across ethnicity and marital status in the bivariate analysis. After multivariate analysis, ethnicity remained a signifi cant correlate for total PMH and the 6 domain-specifi c PMH scores, marital status correlated with Spirituality, educational level was associated with IS; while gender was associated with ES and PGA. Signifi cantly lower PMH total scores were observed for those with depression and anxiety as compared to those without. Conclusion: Socio-demographic correlates of PMH were identifi ed in an Asian community sample. PMH scores were signifi cantly lower among those with depression and anxiety
