Article Synopsis
- Mediation analysis is a valuable tool in neuroscience for understanding how intermediary variables from neuroimaging data influence outcomes, often using structural equation models (SEMs) that assume linear relationships.
- However, there's a gap in research regarding the use of shape space-derived mediators in SEMs, and the linear assumption can reduce accuracy in practical applications.
- The new framework developed for shape mediation analysis addresses these issues by introducing a two-layer shape regression model, allowing for better exploration of relationships between genetic factors, clinical outcomes, and shape-related variables, showing improved accuracy in simulations and real data compared to traditional methods.
Neighborhood Deprivation and Unmet Health Care Needs: A Multilevel Analysis of Older Individuals in South Korea.

October 2019
Objectives: In this study the relationship between neighborhood deprivation and the unmet health care needs of elderly individuals (≥ 65 years) was examined. Some previous studies suggested that neighborhood characteristics affect access to health care, yet research on the unmet needs of older individuals is limited.
Methods: Multilevel logistic regression analysis was used to assess the relationship of neighborhood-level factors with unmet health care needs due to costs, adjusting for individual-level factors, in individuals ≥ 65 years in the 2017 Korean Community Health Survey ( = 63,388).
Objectives: During the outbreak of the Middle East Respiratory Syndrome (MERS) in Korea in 2015, the Korea Centers for Disease Control and Prevention (KCDC) confirmed a case of MERS in a healthcare worker in Daejeon, South Korea. To verify the precise route of infection for the case, we conducted an in-depth epidemiological investigation in cooperation with the KCDC.
Methods: We reviewed the MERS outbreak investigation report of the KCDC, and interviewed the healthcare worker who had recovered from MERS.
Article Synopsis
- Between May and July 2015, 26 cases of Middle East Respiratory Syndrome (MERS) were reported in two hospitals in Daejeon, South Korea, involving one initial case and 25 secondary cases.
- The median incubation period for the virus was 6.1 days, with variations between the two hospitals, and the overall attack rate was 3.7%, particularly higher among inpatients (12.3%) and caregivers (22.5%).
- The case-fatality rate was alarmingly high at 44%, and although cohort quarantine may have reduced wider community spread, further transmission occurred within the quarantined groups, indicating caregivers potentially played a role in spreading the infection.
Objectives: To explore the epidemiological and clinical factors predictive of the case fatality rate (CFR) of Middle East respiratory syndrome-coronavirus (MERS-CoV) infection in an outbreak in Daejeon, the Republic of Korea.
Methods: We reviewed the outbreak investigation reports and medical records of 1 index case and 25 additional MERS cases in hospitals A (14 cases) and B (11 cases), and conducted an in-depth interview with the index case.
Results: The CFR in hospital B was higher than that in hospital A (63.
Objectives: The objective of this study is to investigate associations between contextual characteristics and unmet healthcare needs in South Korea after accounting for individual factors.
Methods: The present study used data from the 2012 Korean Community Health Survey (KCHS) of 228 902 adults residing within 253 municipal districts in South Korea. A multilevel analysis was conducted to investigate how contextual characteristics, defined by variables that describe the regional deprivation, degree of urbanity, and healthcare supply, are associated with unmet needs after controlling for individual-level variables.
