The relationship between childhood trauma and romantic relationship satisfaction
Attachment mediated the relationship between childhood trauma and romantic relationship satisfaction, while social support moderated the relationship between childhood trauma and attachment. These findings suggest that interventions should focus on improving attachment styles and strengthening social support to mitigate the negative effects of childhood trauma on romantic relationships
Exploring the cultivation of psychological resilience in medical students from the perspective of doctor–patient relationship
The current medical model has transitioned from the original biomedical treatment model to a bio-psycho-social model, where patients now have higher demands for service awareness. Consequently, doctor-patient relationships have become a crucial aspect of the contemporary medical process. Currently, psychological resilience among medical students in China tends to be at a moderately lower level. Medical students often exhibit poor psychological qu…
Effectiveness and Reflection

Dental care use and other population characteristics of older Americans with self‐reported chronic conditions in the health and retirement study
These cross-sectional findings establish the relative strength of relationships between dental care use, oral health status, and other population characteristics and eight diagnosed conditions. Further work beyond the scope of this paper is needed to confirm these results as either attributes of those with the disease or causal risk factors for the onset of the condition
Evaluation of Single and Joint Toxicity of Perfluorinated Carboxylic Acids and Copper to Metal-Resistant Arthrobacter Strains
Perfluorocarboxylic acid compounds (PFCAs) and copper have been regarded as ubiquitous environmental contaminants in aquatic ecosystems worldwide. However, data on their possible joint toxic effects on microorganisms are still lacking. To study the combined effects of four PFCAs with different carbon chain lengths and copper, a series of experiments were conducted to explore the acute toxicity of these PFCAs in the absence and presence of copper …
Diversity in the use of specialized dental services by older adults in the United States
Our study identifies diversity in the use of specialized dental services among an older adult population and suggests that more widespread use of routine dental services could potentially improve oral health and limit the need for expensive specialized dental care for this population

We analyzed data for civilian, noninstitutionalized US individuals older than 50 years from the 2006 and 2008 waves of the Health and Retirement Study. We estimated multinomial logistic models of persistent and intermittent use of physician, inpatient hospital, home health, and outpatient surgery over the 2004–2008 sur…
Dental usage under changing economic conditions
Older Americans' dental care utilization appeared to be fairly resilient to changes in household finances; only when wealth fell by 50 percent or more did individuals decrease dental use. This finding might extend to other health-care services that are preventive, routine, and relatively inexpensive
Wealth effect and dental care utilization in the United States
Relative to those living in the wealthiest US households, the likelihood of utilizing dental care appears to decrease with a decline in wealth. The likelihood of utilizing dental care also appears to decrease with a decline in income as well
The influence of comorbidity and other health measures on dental and medical care use among Medicare beneficiaries 2002
Comorbidities and other health status measures are theorized to play either a predisposing or need role in determining health care utilization. The study's findings confirm the dominant role of these measures as predisposing factors limiting access to dental care for Medicare beneficiaries and as need factors producing higher levels of inpatient hospital and other medical care for Medicare beneficiaries
The Influence of Changes in Dental Care Coverage on Dental Care Utilization Among Retirees and Near-Retirees in the United States, 2004–2006
Objectives. We examined dental care utilization transition dynamics between 2004 and 2006 in the context of changing dental coverage status. Methods. We used data from the Health and Retirement Study for persons aged 51 years and older to estimate a multivariable model of dental care use transitions with controls for dental coverage and retirement transitions and other potentially confounding covariates. Results. We found that Americans aged 51 y…

Dental care coverage and retirement
Dental care, generally not covered in Medicare, is an important factor in the decision to seek dental care. It is important to understand the relationship between retirement and dental coverage in order to identify the best ways of improving oral health and access to care among older Americans
Dental care utilization and retirement
The authors conclude from this study that full retirement accompanied by reduced income and dental insurance coverage produces lower utilization of dental services. However, they also show that retirement acts as an independent variable, whereas income, coverage, and free time (unobserved) act as intervening variables
Dental care expenditures and retirement
Although having dental coverage is a key determinant of the level of OOP expenditures on dental care; spending is higher among those without coverage than those who have dental insurance. We also found that while retirement has no independent effect on OOP dental expenditures once controlling for coverage, dental coverage rates are much lower among retirees
