A systematic review and meta-analysis of the relationship between heavy smoking and probability discounting.

BACKGROUND AND OBJECTIVES: Probability discounting (PD), which refers to the process of adjusting the value of future probabilities when making decisions, is a method of measuring impulsive decision-making; however, the relationship between PD and nicotine remains unclear. The current study aimed at investigating the significance of PD in individuals who smoke. METHODS: According to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we searched the PubMed, Embase, PsycINFO, and Web of Science databases for articles comparing individuals who smoke and their tobacco-naïve controls using PD task as outcome measure from inception to May 2023. The main outcome was an overall difference in PD function, while subgroup analysis and meta-regression were conducted to examine the analysis methods and the moderators of PD. RESULTS: Fourteen studies in total involving 384 individuals who smoke and 493 controls (mean age = 24.32 years, range = 15.1-38.05 years) were analyzed. The effect of smoking on PD was significant (g = 0.51, p = .02). The discounting parameter from the equation, compared to the area under the curve, was more sensitive to estimating PD function (p = .01). Regression analysis showed positive correlations of PD with female percentage, age, and the number of probability options (all p < .04), but not with the number of choices at each probability and maximum reward magnitude (all p > .07). There was no significant publication bias across the eligible studies (p = .09). CONCLUSION AND SCIENTIFIC SIGNIFICANCE: Our findings, which are the first to demonstrate a smaller PD (i.e., prone to risk-taking) in individuals who smoke, shed light on the appropriate analysis method, gender effect, age, and probability options on the PD function.

Quality of Life Among Geriatric Community Members Following the Kaohsiung Gas Explosion: A 5-Year Cross-Sectional Study.

OBJECTIVE: The aim was to conduct a follow-up study of the quality of life (QoL) and to measure lifestyle factors among the aging survivors of a petrochemical gas explosion in Taiwan 5 years after the event. METHODS: A community-based survey with cross-sectional assessments was conducted with residents of a community who experienced a petrochemical gas explosion 5 years after the disaster. Short Form 12v2 (SF-12v2) was used to survey a representative sample of participants. RESULTS: The risk factors for different QoL subscales were stressors and chronic physical illness, and the protective factors were higher income and better diet and exercise habits. The elderly participants had better diet and exercise habits than the younger participants in this survey. Aging had a negative impact on the physical QoL subscales [physical functioning (PF), bodily pain (BP), general health (GH), Physical Component Summary (PCS)] but a positive impact on psychological QoL subscales [vitality (VT), social functioning (SF), emotional problems (RE), mental health (MH), Mental Health Component Summary (MCS)]. CONCLUSIONS: While participants' psychiatric status had improved after 5 years, their QoL continued to be affected, especially in those with stress and physical illness. The elderly groups maintained a relatively acceptable QoL in terms of psychological aspects. Postdisaster treatment and follow-up should be addressed to a greater degree, especially in victims with mental illness or chronic illness and those with fewer socioeconomic resources.

Characteristics of children and adolescents presenting to the emergency department with self-inflicted injury: Retrospective analysis of two teaching hospitals.

BACKGROUND: Data on Taiwanese adolescents with self-inflicted injuries are limited. We describe the epidemiology of children and adolescents visiting the emergency department for self-inflicted injuries in two geographically distinct teaching hospitals. METHODS: Medical records of children 0-18 years old who visited the emergency department of Taipei Tzu Chi Hospital and Chi Mei Medical Center, Tainan between 2016 and 2019 coded with relevant diagnoses were reviewed. Visits with documented self-inflicted injury were included. RESULTS: During the 4-year period, 62 children made 74 emergency visits for self-inflicted injury. A total of 88% of visits were made by children with a psychiatric diagnosis, with depressive disorders being the most common (57%). Interpersonal relationship issue was cited as a trigger for self-harm in 49% of visits. Adjusted for annual visit volumes, self-harm visits per 10,000 pediatric emergency visits increased nearly 5 fold between 2016 and 2019, with the most prominent increase in the final year. Poisoning was the most common mechanism of injury and was frequently used by females, as compared to males who tended to jump from heights. Up to 96% of adolescents with previous self-harm seen at the emergency department had sought psychiatric help in the past year. Urban-rural inequity in mental health resource utilization was observed. CONCLUSIONS: Visits to the emergency department for self-inflicted injuries among children and adolescents increased, most remarkably in 2019, for both hospitals. Intentional poisoning with prescription and over-the-counter medications was the most common method. There was a high prevalence of psychiatric disorders in our study population. As the emergency department is likely the first point of medical contact for such visits, emergency personnel should be trained appropriately on managing such patients.

Translation and Validation of a Chinese Version of the Cleveland Adolescent Sleepiness Questionnaire.

PURPOSE: The Cleveland Adolescent Sleepiness Questionnaire was originally developed and published in English and has served as a valid and effective tool for the assessment of adolescents' experiences with sleepiness in a variety of situations. To allow for comparisons between sleepiness in adolescents from different cultures, and with different linguistic backgrounds, reliable and valid measurement tools are necessary. The purpose of this study was to translate and validate a Chinese version of the Cleveland Adolescent Sleepiness Questionnaire (C-CASQ). MATERIALS AND METHODS: Sensitivity, specificity, internal consistency, and criterion validity data for the C-CASQ were tested using 458 adolescents in Taiwan. Data from 191 participants were used to establish internal consistency reliability and conduct exploratory factor analysis (EFA), while data from 267 participants were used to establish criterion validity and conduct confirmatory factor analysis (CFA). Initial criterion validity was established through a comparison of the C-CASQ with scores from the Chinese version of the Morningness-Eveningness Scale for Children, a measure of chronotype. RESULTS: EFA resulted in four factors, consistent with the original English version of the CASQ, while CFA established goodness of fit. The scale demonstrated acceptable to good internal consistency (α = 0.77~0.86). Initial criterion validity was evident as the total score and each of the subscale scores on the C-CASQ was significantly higher (greater sleepiness) in evening-types. CONCLUSION: The C-CASQ appears to be a psychometrically sound measure to evaluate sleepiness in Chinese-speaking adolescents.

A Community Survey of Quality of Life and Psychiatric Disorders among Residents Following the Kaohsiung Gas Explosion: a 5-Year Cross-Sectional Follow-Up Study.

To investigate factors associated with quality of life (QoL) and disaster-related psychiatric disorders, including posttraumatic stress disorder (PTSD) and major depressive episode (MDE), in the survivors of a gas explosion in Taiwan 5 years after the event. A community-based cross-sectional study of residents from an area that experienced a gas explosion was conducted 5 years after the event. The Short Form 12v2 (SF-12v2) was used to screen 2511 participants. The Disaster-Related Psychological Screening Test (DRPST) was used to assess probable MDE and PTSD. A total of 2511 participants, including 604 males and 1907 females, completed the QoL survey. The average age was 56.02 ± 16.78 years, and most participants were in the ≧65 age group (39.7%). The males had better QoL in the physical dimensions. Lifestyle was significantly positively associated with QoL. A total of 894 participants completed the DRPST, which showed some individuals with probable MDE (n = 93, 10.4%), probable PTSD (n = 22, 2.5%), or probable MDE and PTSD (n = 49, 5.5%); most people had no MDE or PTSD (n = 730, 81.7%). Those in the probable PTSD or MDE groups were significantly more likely to be female or to be experiencing stressors (p < 0.001). The participants continued to be affected by the disaster based on their QoL, even 5 years later. Females had a higher risk of probable psychiatric disorders and poorer QoL in the physical dimensions. Long-term follow-up, interventions and investigations after a disaster are needed.
