ABSTRACT
Background: The COVID-19 pandemic has demonstrated the need for medical students to be prepared to make adequate decisions during unique challenges presented during pandemics. Objective: This review aims to provide a comprehensive look into the current global literature that discusses medical curricula on clinical ethical issues during a pandemic. Methods: The scoping review methodology was divided into three stages. Phase 1, planning, involved identifying key terms, selecting databases, creating a search criterion, and deciding on inclusion and exclusion criteria. Phase 2, study selection and data extraction, included screening the title and abstract, reviewing the complete text, and extracting data. Phase 3, analysis and write-up, comprised analyzing the extracted information and composing the review. Results: 10 studies were included and underwent data extraction as part of the review. The studies varied by country, study design, institution, education setting, and course titles. Ethical issues identified while reviewing the curriculums were resource allocation, healthcare worker obligations, personal protective equipment, disease control, communication, management protocols, and patient care. Conclusion: This review revealed a lack of literature regarding the curriculum for medical students on ethical issues during a pandemic. This indicates a need for reform in medical education to cover pandemic preparedness and ethical concerns during a pandemic. If medical schools do not address this gap, future physicians may encounter the same issues healthcare workers faced during the COVID-19 pandemic.
ABSTRACT
OBJECTIVE: Trichotillomania (TTM) is a mental health disorder characterized by repetitive urges to pull out one's hair. Cognitive deficits have been reported in people with TTM compared to controls; however, the current literature is sparse and inconclusive about affected domains. We aimed to synthesize research on cognitive functioning in TTM and investigate which cognitive domains are impaired. METHODS: After preregistration on the International Prospective Register of Systematic Reviews (PROSPERO), we conducted a comprehensive literature search for papers examining cognition in people with TTM versus controls using validated tests. A total of 793 papers were screened using preestablished inclusion/exclusion criteria, yielding 15 eligible studies. Random-effects meta-analysis was conducted for 12 cognitive domains. RESULTS: Meta-analysis demonstrated significant deficits in motor inhibition and extradimensional (ED) shifting in people with TTM versus controls as measured by the stop-signal task (SST) (Hedge's g = 0.45, [CI: 0.14, 0.75], p = .004) and ED set-shift task (g = 0.38, [CI: 0.13, 0.62], p = .003), respectively. There were no significant between-group differences in the other cognitive domains tested: verbal learning, intradimensional (ID) shifting, road map spatial ability, pattern recognition, nonverbal memory, executive planning, spatial span length, Stroop inhibition, Wisconsin card sorting, and visuospatial functioning. Findings were not significantly moderated by study quality scores. CONCLUSIONS: Motor inhibition and ED set-shifting appear impaired in TTM. However, a cautious interpretation of results is necessary as samples were relatively small and frequently included comorbidities. Treatment interventions seeking to improve inhibitory control and cognitive flexibility merit exploration for TTM.
