Internship, the transition period from medical student to junior doctor, is highly stressful for interns in the West; however, little is known about the experience of interns in coping with stress in Taiwan. This study aimed to develop a model for coping with stress among Taiwanese interns and to examine the relationship between stress and learning outcomes. For this qualitative study, we used grounded theory methodology with theoretical sampling. We collected data through in-depth interviews and participant observations. We employed the constant comparative method to analyse the data until data saturation was achieved. The study population was 124 medical interns in a teaching hospital in northern Taiwan; 21 interns (12 males) participated. Data analysis revealed that the interns encountered stressors (such as sense of responsibility, coping with uncertainty, and interpersonal relationships) resulting from their role transition from observer to practitioner. The participants used self-directed learning and avoidance as strategies to deal with their stress. A self-directed learning strategy can be beneficial for an intern’s motivation to learn as well as for patient welfare. However, avoiding stressors can result in less motivation to learn and hinder the quality of care. Understanding how interns experience and cope with stress and its related outcomes can help medical educators and policy makers improve the quality of medical education by encouraging interns’ self-directed learning strategy and discouraging the avoidance of stressors.

Purpose: During the coronavirus disease 2019 (COVID-19) pandemic, visits to emergency department (ED) have significantly declined worldwide. The purpose of this study was to identify the trend of visits to ED for different diseases at the peak and slack stages of the epidemic. Patients and Methods: This was a retrospective observational study conducted in a tertiary referral medical center in northern Taiwan. We recorded weekly ED visits for myocardial infarction with or without ST-elevation (STEMI or NSTEMI), out-of-hospital cardiac arrest (OHCA), acute stroke, and congestive heart failure from 2016 to 2021. We compared the local epidemic peak periods (calendar weeks 4– 18, 2020 and calendar weeks 21– 31, 2021) and its corresponding slack periods (calendar weeks 4– 18, 2021 and calendar weeks 21– 31, 2020) with the baseline period (2016– 2019) using Mann–Whitney test to identify the difference. Results: We observed a significant decline in ED visits (median [Q1, Q3]) during the epidemic for OHCA (6 [5, 7] and 5 [4, 6], p = 0.046, for baseline and peak period, respectively, in week 4– 18), acute stroke (41.5 [38, 47] and 35 [28, 39], p < 0.001, in week 4– 18, 40 [35, 45] and 35 [28, 40], p = 0.039, in week 21– 31) and CHF (28 [24.25, 33] and 19 [12, 23], p < 0.001, in week 4– 18, 18 [16, 23] and 13 [11, 16], p = 0.001, in week 21– 31). Significant difference was not observed in patients with NSTEMI and STEMI in both week 4– 18 and 21– 31, and cardiac arrest in week 21– 31. There was a rebound in ED visits in the slack period. Conclusion: This study revealed that ED visits significantly declined during the COVID-19 epidemic and rebounded in the slack period. The trend was significant for acute stroke and heart failure but was relatively less prominent effect for emergent events such as cardiac arrest or myocardial infarction.

Ketamine immunoassay urine drug screen (UDS) is commonly used in Taiwan. However, there was limited report about possible drug which may cause false positive results in ketamine screen test. We report two cases who used quetiapine showed positive in ketamine urine immunoassay screen initially, and found to be false positive in confirmation test. Clinicians should be aware of the false positive result of ketamine UDS caused by currently used medication.

Introduction: Sjogren’s syndrome is an autoimmune disease that commonly involves exocrinopathy. Although studies have reported psychiatric manifestations resulting from Sjogren’s syndrome, few studies have focused on such manifestations in pediatric patients. Herein, we present a case of an adolescent girl with depression and involuntary self-harm behaviors related to Sjogren’s syndrome with central nervous system involvement.Case presentation: A 15-year-old girl, with an underlying history of epilepsy, developed depressive symptoms of a year’s duration, accompanied by three seizure episodes and involuntary self-harm behaviors. The self-harm behaviors, which included head banging and arm scratching, were sudden onset, involuntary, and unable to be recalled afterwards. After admission to our ward, the patient was positive for serum antinuclear antibodies and Schirmer’s test. Moreover, 24-hour electroencephalography revealed epileptiform discharges during the mood swing episodes. Positive findings for antinuclear antibodies and anti-SSA antibodies in both serum and cerebrospinal fluid, suggested central nervous system involvement in Sjogren’s syndrome. After rituximab treatment, her mood became euthymic, and her involuntary self-harm behaviors ceased.Conclusion: Central nervous system involvement leading to psychiatric presentations has rarely been reported in adolescents with Sjogren’s syndrome. When treating adolescent patients with involuntary self-harm behaviors and neurological symptoms, it is crucial to consider autoimmune encephalitis related to Sjogren’s syndrome in the differential diagnosis.

Doujin (どうじん) is a Japanese term referring to a circle where people share the same interests, usually something that belongs to the Anime, Comics, and Games (ACG) subculture. Individuals who belong to it and create related works, known as ACG doujin creators, are usually described as socially awkward and at potential risk of isolation. In such a context, they may theoretically exhibit higher autistic traits and manifest camouflaging tendencies, which may consequently be associated with their mental health. Nonetheless, the impact of autistic traits and camouflaging on mental health in this subculture remains significantly underexplored. We recruited 183 Taiwanese ACG doujin creators (age ranges from 18 to 41, 146 female and 37 male) via social networking platforms. Participants completed Chinese online surveys assessing socio-demographic information, doujin activities, past psychiatric history, the 35-item Version of Autism-Spectrum Quotient (AQ-35), Chinese version Camouflaging Autistic Traits Questionnaire (CAT-Q-Ch), the General Anxiety Disorder-7 (GAD-7), and the Patient Health Questionnaire-9 (PHQ-9). Linear regression analysis was employed to examine the associations between the aforementioned scales. Our findings revealed that among ACG doujin creators, descriptively higher level of AQ-35 and CAT-Q-Ch than previous studies were found. Moreover, we observed a positive association between camouflaging behaviours and most AQ-35 subscales, with the exception of the mindreading subscale. Additionally, we identified that both camouflaging and autistic traits were significantly linked to higher PHQ-9 and GAD-7 scores. Through this study, we gained insight into the distinctive characteristics of autistic traits, camouflaging behaviours, and mental health among Taiwanese ACG doujin creators, as the associations between the factors mentioned above are divergent compared to previous research. This topic demonstrated that camouflaging is also associated with adverse mental health in a subculture group.

Objective Anxious depression is a prevalent characteristic observed in Asian psychiatric patients diagnosed with major depressive disorder (MDD). This study aims to investigate the prevalence and clinical presentation of anxious depression in Taiwanese individuals diagnosed with MDD.Methods We recruited psychiatric outpatients aged over 18 who had been diagnosed with MDD through clinical interviews. This recruitment took place at five hospitals located in northern Taiwan. We gathered baseline clinical and demographic information from the participants. Anxious depression was identified using a threshold of an anxiety/somatization factor score ≥7 on the 21-item Hamilton Rating Scale for Depression (HAM-D).Results In our study of 399 patients (84.21% female), 64.16% met the criteria for anxious depression. They tended to be older, married, less educated, with more children, and an older age of onset. Anxious depression patients had higher HAM-D and Clinical Global Impression–Severity scale score, more panic disorder (without agoraphobia), and exhibited symptoms like agitation, irritability, concentration difficulties, psychological and somatic anxiety, somatic complaints, hypochondriasis, weight loss, and increased insight. Surprisingly, their suicide rates did not significantly differ from non-anxious depression patients. This highlights the importance of recognizing and addressing these unique characteristics.Conclusion Our study findings unveiled that the prevalence of anxious depression among Taiwanese outpatients diagnosed with MDD was lower compared to inpatients but substantially higher than the reported rates in European countries and the United States. Furthermore, patients with anxious depression exhibited a greater occurrence of somatic symptoms.
