Development and Evaluation of the Life Respect Enhancement Program for Nursing Officers

Purpose@#The present study was conducted to develop the Life Respect Enhancement Program and test its effectiveness on suicide knowledge, suicide intervention skills, self-efficacy in suicide prevention, and gatekeeper behaviors among nursing officers. @*Methods@#The program was developed according to the ADDIE model and finalized after practical need analysis, expert verification, and a preliminary study.The present study used a concurrent embedded mixed-method research design. To compare the effects of the Program and the control group on the outcome variables, a quantitative study was conducted using a nonequivalent control group with a pretest-posttest design.Quantitative data were analyzed using c 2 -tests, t-tests, and RM-ANOVA. A qualitative study was conducted using FGI with six members of the experimental group 3 months after intervention completion. @*Results@#In total, 56 nursing officers participated in the 3-month follow-up test. Compared to the control group, the experimental group showed significant improvements in suicide knowledge, suicide intervention skills, and self-efficacy in suicide prevention scores at post-test. The significant group differences in suicide knowledge and suicide intervention skills were maintained at 3 months. The gatekeeper behavior scores of the experimental group were also significantly higher than those of the control group at 3 months. Qualitative analysis of the participants’ experiences with the Program yielded two themes and seven sub-themes. @*Conclusion@#The newly developed Life Respect Enhancement Program demonstrates significant effects on suicide knowledge, suicide intervention skills, and gatekeeper behaviors. Thus, this program is recommended to promote suicide prevention competencies among nursing officers in military clinical settings.

A Systematic Review of Suicide Prevention Programs for Healthcare Personnel / 정신간호학회지

PURPOSE: The purpose of this study was to systematically review the suicide prevention programs for healthcare personnel to identify contents, formats, and strategies essential for effective suicide prevention programs. METHODS: A systematic search using key words in English and Korean was conducted using 10 electronic databases, including EMBASE, MEDLINE, and RISS. Of 794 publications identified, 9 studies were finally included in this systematic review. The Scottish Intercollegiate Guidelines Network (SIGN) was used for the quality assessment. RESULTS: Of the nine experimental studies, seven studies used randomized controlled trials (RCTs), and two used quasi-experimental designs. Overall, suicide prevention programs were found to be effective in improving competencies (e.g., knowledge, communication skills, and attitudes) of healthcare personnel working in diverse settings. Limitations of these studies included a lack of rigorous research designs and reliable and universal outcome measures. Paradoxically, none of the studies were conducted in South Korea, which consistently has the highest suicide rate of all OECD countries. CONCLUSION: Suicide prevention programs for health personnel can be an effective way to improve competency of healthcare personnel in preventing suicide. These findings will serve as a foundation for the development of suicide prevention programs by Korean healthcare personnel.

Suicide Risk Assessments: Which Suicide Risk Factors Psychiatric Residents Consider Significant?

OBJECTIVE: Patients visiting the emergency department (ED) after a suicide attempt are generally assessed for suicide risk by psychiatric residents. Psychiatric residents' competence in evaluating the risk posed by the patients who attempted suicide is critical to preventing suicide. METHODS: We investigated factors considered important by psychiatric residents when evaluating suicide risk. This study included 140 patients admitted to the ED after attempting suicide. Psychiatric residents rated patients' severity of current and future suicide risk as low/moderate/high using the Brief Emergency Room Suicide Risk Assessment (BESRA). The association between each BESRA variable and level of suicide risk was analyzed. RESULTS: Many factors were commonly considered important in evaluating the severity of current and future suicide risk. However, the following factors were only associated with future suicide risk: female gender, having no religion, family psychiatric history, history of axis I disorders, having a will, harboring no regrets, and social isolation. CONCLUSION: Psychiatric residents use diverse factors when assessing suicide risk. Psychiatric residents might put more emphasis on non-modifiable demographic and clinical factors, concrete evidence showing suicide determination, and social isolation to assess the risk of future suicide.

Amelioration of Cerebral Ischemic Injury by a Synthetic Seco-nucleoside LMT497

Recently, we reported that the A3 adenosine receptor (A3AR) agonist LJ529 (2-chloro-N6-(3-iodobnzyl)-5'-N-methylcarbamoyl-4'-thioadenosine) reduces cerebral ischemic injury via inhibition of recruitment of peripheral inflammatory cells into ischemic brain lesion. A3AR agonists, however, are known to possess anti-platelet activity, which may deter the combination therapy with tissue plasminogen activator for the therapy of cerebral ischemic stroke. Thus, the present study investigates the neuroprotective/anti-ischemic effect of a synthetic seco-nucleoside, LMT497 ((S)-2-((R)-1-(2-chloro-6-(3-iodobenzylamino)-9H-purin-9-yl)-2-hydroxyethoxy)-3-hydroxy-N-methylpropanamide) with little anti-platelet activity. LMT497 neither showed A3AR binding activity nor anti-platelet activity. In our present study LMT497 significantly attenuated the injury/death of cortical neurons exposed to oxygen-glucose deprivation (OGD) followed by re-oxygenation (R). LMT497 significantly reduced the ascending cellular level of reactive oxygen species under ischemic conditions by increasing the superoxide dismutase (SOD) levels. LMT497 also inhibited the migration of microglia which mediates inflammatory responses in ischemia. In rats subjected to middle cerebral artery occlusion (MCAO, 1.5 h) followed by reperfusion, LMT497 largely reduced brain infarction volume, and edema, and improved neurological score. Therapeutic efficacy of LMT497 was obtained by twice treatments even at 10 h and 18 h after the onset of ischemia. Collectively, LMT497 could be a therapeutic drug candidate with a wide therapeutic time window for the treatment of cerebral ischemic stroke.

Neurocognitive Deficits in Patients with Schizophrenia and Unaffected First-Degree Relatives

OBJECTIVES: This study aimed to identify the differences and the profiles of cognitive deficits in remitted patients with schizophrenia and first-degree relatives of schizophrenic probands. METHODS: A total of 26 remitted states of schizophrenia patients were included in the study and the same number of unaffected first-degree relatives of schizophrenic probands and healthy controls were matched for age, sex, years of education. Cognitive function of all participants was measured by using the Digit span test, the Continuous performance test, the Rey auditory & visual learning test, the Complex figure test, the Verbal fluency test, the Wisconsin card sorting test and the Finger tapping test. The effects of subsyndromal symptomatology and general intelligence score were controlled. RESULTS: Schizophrenia patients' group showed more significant impairment than other groups in verbal memory (learning, immediate recall, delayed recall), visual memory (copy, immediate recall, delayed recall) and cognitive flexibility domains. The family group and the patient group commonly performed significantly worse than healthy controls in working memory and verbal fluency (category) tests. There were no differences in sustained attention, psychomotor performance. CONCLUSIONS: Our research shows that the deficit in working memory and verbal fluency could be strong candidates of endophenotypic marker in schizophrenia.

Characteristics of Drug Overdose in Young Suicide Attempters

OBJECTIVE: Few studies have focused on the characteristic features of drug overdose in children and adolescents who have attempted suicide in Korea. The present study examined the characteristics of drug overdose in children and adolescents who visited the emergency room following drug ingestion for a suicide attempt. METHODS: The medical records of 28 patients who were treated in the emergency room following a drug overdose from January 2008 to March 2011 were analyzed. Demographic and clinical variables related to the suicide attempts were examined. RESULTS: The mean age of the patients was 16.6+/-1.7 years (range 11-19 years), and 20 of the patients (71.4%) were female. Most of the patients (n=23, 82.1%) overdosed on a single drug; acetaminophen-containing analgesics were the most common (n=12, 42.9%). Depression was the most common psychiatric disorder (n=22, 78.6%), and interpersonal conflict was the most common precipitating factor of the suicide attempts (n=11, 39.3%). This was the first suicide attempt for approximately 80% of the patients. About one fourth of the patients (n=7, 25%) had follow-up visits at the psychiatric outpatient clinic. CONCLUSION: Early screening and psychiatric intervention for depression may be an important factor in preventing childhood and adolescent suicide attempts. Developing coping strategies to manage interpersonal conflicts may also be helpful. Moreover, policies restricting the amount and kind of drugs purchased by teenagers may be necessary to prevent drug overdose in this age group.
