The rapid advancement of digital dentistry has enabled the integration of digital technologies into full-mouth rehabilitation, improving communication between clinicians and dental technicians while greatly enhancing treatment efficiency.This case report details the treatment of a patient with severe tooth erosion and wear, where full-mouth rehabilitation with an increase in vertical dimension was planned. Four digital tools‒an intraoral scanner, facial scanner, T-scan, and Jaw Motion Analyzer‒were used to collect and integrate data, which were then utilized to create a virtual patient through CAD software for the design and fabrication of the prosthesis. The effective use of these digital technologies supported the achievement of a stable occlusion and resulted in both functional and esthetic outcomes. This case demonstrates the effectiveness of a digital workflow in enhancing the accuracy and efficiency of the treatment process, producing clinically satisfactory results.

Background: Though accumulating evidence suggests an association between childhood trauma and anhedonia, further analysis is needed to consider specific traumatic dimensions, both traits and state anhedonia, and the role of circulating proteins. Therefore, this study investigated the association between different types of childhood traumas and their influence on anhedonia-related symptoms, and to evaluate the influence of anhedonia traits and plasma proteins as mediators. Methods: This study included 170 patients with schizophrenia, bipolar disorder, major depressive disorder, and healthy controls aged 19–65 years. Multiple reaction monitoring was performed to quantify plasma proteins, and 464 proteins were analyzed. The association between childhood trauma dimensions, anhedonic traits, and related symptoms was analyzed with linear regression. A series of mediation analyses was performed to determine whether anhedonic traits and plasma proteins mediated the association between childhood trauma and anhedonia-related symptoms. Results: Childhood emotional neglect was significantly associated with anhedonic traits and anhedonia-related symptoms. Mediation analysis revealed that the indirect effect of anhedonic traits for childhood emotional neglect on anhedonia-related symptoms (effect = 0.037; bias-corrected CI, 0.009 to 0.070) was statistically significant. The indirect effect of plasma TNR5 for anhedonic traits on anhedonia-related symptoms was statistically significant (effect = −0.011; bias-corrected CI, −0.026 to −0.002). Serial mediation analysis revealed that the indirect effect of childhood emotional neglect on anhedonia-related symptoms via anhedonic traits and TNR5 was statistically significant (effect = 0.007; biascorrected CI, 0.001 to 0.017). Conclusion Anhedonic traits and plasma TNR5 protein levels serially mediated the association between childhood emotional neglect and anhedonia-related symptoms.The study highlights the importance of considering both psychopathological traits and biological correlates when investigating the association between childhood trauma and psychopathological symptoms.

Purpose: The living arrangements of elderly persons can play a crucial role in their health.This study evaluated the association between living arrangements and frailty among elderly Korean men. Methods: The cross-sectional data from the Korea National Health and Nutrition Examination Survey (2014–2019) were used. A total of 3,198 men aged 65 years or older were divided into a living alone group (LA, n = 393) and a not living alone group (NLA, n = 2,805). The dietary intake data was obtained from a single 24-hour recall. The food variety score (FVS) was defined as the number of foods items consumed in one day. Frailty was defined as the presence of three or more of the modified Fried frailty phenotype criteria. The association between living arrangements and frailty was analyzed by multiple nominal logistic regression. Results: The LA group showed significantly lower FVSs than the NLA group. The intakes of fruit, vegetables, fish and shellfish, fiber, and key antioxidant nutrients such as vitamins A and C, were lower in LA than in NLA. Multiple nominal logistic regression revealed a higher odds ratio (OR) for frailty in the LA group compared to the NLA group (OR [95% confidence interval], 2.05 [1.12–3.74]; p = 0.019). Conclusion These findings suggest that the increased risk of frailty among elderly men living alone may be partially associated with their lower dietary variety, particularly reduced intake of essential nutrients from fruit, vegetables, fish, and shellfish, highlighting their vulnerability to suboptimal nutrition. Thus, increasing diversity in food intake could be a useful dietary strategy to prevent the frailty of the living alone elderly.

Background: Polycyclic aromatic hydrocarbons are generated from the incomplete combustion of organic materials such as fossil fuels and wood. These compounds, often inhaled, cause respiratory issues like asthma and chronic obstructive pulmonary disease due to oxidative stress and inflammation. Pohang, South Korea’s iron and steel hub, experiences significant polycyclic aromatic hydrocarbons emissions from extensive industrial activities and heavy truck movements. This study investigates the link between urinary polycyclic aromatic hydrocarbons metabolites and respiratory diseases among Pohang residents, considering their cumulative exposure and duration of residency. Methods: Utilizing data from the National Environmental Research Institute’s health impact assessment conducted between 2012 and 2015, this study included 1,189 participants from Pohang. Urinary concentrations of polycyclic aromatic hydrocarbons metabolites served as exposure indicators. The study assessed the correlation between these metabolite levels and self-reported respiratory diseases, considering variables such as duration of residence, smoking status, and occupational exposures. Statistical analyses involved logistic regression and fixed-effect meta-analysis. Results: The findings indicate a significant association between elevated levels of polycyclic aromatic hydrocarbons metabolites and an increased risk of respiratory diseases, particularly among those in the highest exposure quartile. The study also found a notable dose-response relationship, emphasizing the heightened risk with longer residency durations near the industrial complex. Despite yearly fluctuations, the trend suggests a persistent risk associated with high polycyclic aromatic hydrocarbons exposure. Conclusions Elevated exposure to polycyclic aromatic hydrocarbons near industrial areas such as the Pohang Industrial Complex is significantly associated with an increased prevalence of respiratory diseases. The study underscores the importance of implementing public health strategies to reduce polycyclic aromatic hydrocarbons exposure, especially in industrial regions. Future research should broaden the scope of polycyclic aromatic hydrocarbons metabolites analyzed and consider comprehensive exposure histories to better understand the relationship between polycyclic aromatic hydrocarbons exposure and respiratory health outcomes.

Secondary dyslipidemia, characterized by elevated blood cholesterol and triglycerides, arises from various underlying conditions. The identification and appropriate handling of these causes is crucial for effective treatment. Major contributors include unhealthy diets, diseases impacting lipid metabolism, and medication side effects. Prioritizing the correction of secondary causes before initiating conventional lipid-lowering therapies is essential. Subsequent lipid profiles guide the selection of appropriate guideline-based lipid-lowering interventions.
