Objectives: This study aimed to examine the association between anticholinergic burden, cognitive function, and clinical severity in elderly patients with schizophrenia to suggest safer medication treatment strategies. Methods: A cross-sectional study was conducted with 60 patients aged 60-90 years diagnosed with schizophrenia according to Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria at the National Center for Mental Health. Participants with Clinical Global Impression-Severity (CGS-S) scores ≤4 were included. The Korean Version of the Consortium to Establish a Registry for Alzheimer’s Disease assessment Packet, the 2nd Edition (CERAD-K), CGI-S, and total Anticholinergic Cognitive Burden (ACB) scores were assessed. Statistical analyses included Mann-Whitney tests, Bootstrap analysis of covariance, and Spearman correlations. Results: The mean age was 69.52±6.33 years, with 66.67% female participants. The mean total ACB score was 4.30±2.42, with 80% of patients having scores ≥3. High ACB group (n=48) showed significantly higher CGI-S scores (3.13±0.73 vs. 2.67±0.49, p=0.030) and lower performance in Word List Memory, Constructional Praxis, and Constructional Recall domains. After adjusting for education year, age, and sex, high ACB group showed significantly lower CERAD-K total score I than the low ACB group (F=5.947, p=0.018). Total ACB score also showed significant negative correlations with CERAD-K total score I (r=-0.32, p=0.011). Conclusion High anticholinergic burden in elderly schizophrenia patients was significantly associated with cognitive impairment and symptom severity. These findings suggest the need for careful medication adjustment in this population.

Background: An airway assessment is usually best performed before an elective operation. But in an emergency operation, proper airway assessment can often be difficult. Fiberoptic intubation is a powerful and safe technique to deal with airway difficulty, but it requires a lot of training to be able to perform correctly. There are various specialized oral airways for fiberoptic intubation, but none of them have perfect functionality.CaseA 75-year-old male (body weight 71.6 kg, height 159.3 cm, body mass index 28.22 kg/m2) was diagnosed with acute appendicitis, and it was decided to do a laparoscopic appendectomy. After the induction of general anesthesia, it was impossible to insert the direct laryngoscope deep enough for vocal cord visualization without damaging the teeth because of limited mouth opening. We successfully performed fiberoptic intubation with a newly modified Guedel airway via a longitudinal channel on the convex side and a distal opened lingual end. Conclusions Our modified Guedel airway can be useful in assisting fiberoptic intubation in unexpectedly difficult airway situations.

BACKGROUND: The suicide rate in Korea has been the highest among the Organization for Economic Cooperation and Development countries since 2003. However, there is a lack of in-depth data regarding the characteristics of suicide attempters. Understanding the intent of suicide attempters will help improve the effectiveness of suicide prevention strategies. Therefore, to provide a resource for developing the necessary interventions, this study aimed to examine the differences in suicide-related and clinical variables according to the strength of suicidal intent. METHODS: The subjects were 328 suicide attempters admitted to emergency departments at 5 university hospitals in Daegu-Gyeongbuk province between 2011 and 2014. We used various scales to examine suicide-related and clinical variables and a structured questionnaire to explore psychosocial characteristics. We evaluated suicidal intent using the Pierce Suicide Intent Scale and a clinician-rated scale that measured suicidal authenticity. RESULTS: Individuals with high suicidal intent were significantly older, had higher Hamilton Depression Rating Scale (HDRS) scores, higher rates of premeditation, and sustained suicidal ideation. Furthermore, suicide methods, timing, and psychiatric treatment histories differed by the strength of subjects' suicidal intent. Moreover, multiple logistic regression showed that depressed mood as a reason for attempting suicide, premeditation, and higher HDRS scores were significantly associated with higher suicidal intent. CONCLUSION: Depression, premeditation, older age, and sustained suicidal ideation were characteristics of individuals with high suicidal intent, and it is necessary to evaluate and monitor these factors to prevent repeated suicide attempts.
