This is the first study to report an increased HR for subsequent periodontitis among CD patients when compared to matched comparison subjects without IBD. The protective effect of some pharmaceuticals may suggest that treatment of CD protects against periodontitis.

The topic of suicide has long been an important socioeconomic issue studied in many countries. Suicides inject an atmosphere of unrest into society, and media attention furthers that social uneasiness. From the viewpoint of economics and management, suicide is a waste of human resource: it decreases the labor force in society and deteriorates human capital. This paper provides a series of analyses of suicide rate based on theoretical reasoning and empirical approaches. Aggregate data from G7 countries are obtained and stacked into panel data for analysis. Data are collected for different age groups. Even though suicide issues have been extensively discussed in the past, newly developed econometric tools are applied to her. Beyond previously recognized relationships between economic factors and suicide rates findings include that unemployment strikes men more than women in terms of psychological pressure: for middle age or older women, unemployment may even be positive for the entire family; and female labor force participation exerts pressure on male counterparts and increases its suicide rate. As a result, a low income family with an unemployed man and an employed woman is at high risk for adult male suicide.

Cervical cancer is one of the leading causes of cancer deaths in Taiwan. To investigate the disease cost and then raise awareness of the importance of screening for cervical cancer and promote early detection, this paper employs contingent valuation and willingness to pay (WTP) method to study how health-related quality of life, disease severity, and after-treatment disease status affect patients' WTP for a complete remission of the disease. The inclusive criteria for the study were primary case outpatients at least 3 months after they had received therapy at the time of our study period. Face-to-face interviews were conducted for the retrospective format of the survey. The result of the study indicates a lifetime WTP of $US21 221.96 for Taiwanese cervical cancer patients, which is significantly higher than the cost of screening for early detection. Disease stages do not show a consistent pattern in influencing WTP, but patients with surgery are willing to pay a significantly higher amount for a complete remission from the disease than patients without. In addition, mental health, positive attitudes toward life, and quality of life also are key factors that influence WTP.
