Objectives: The purpose of the study was to investigate the factors affecting unmet dental care needs among elderly living alone. Methods: The study subjects were 19,019 elderly living by themselves, who participated in the Korea Community Health Survey 2018 (KCHS, 2018). The data were analyzed using frequency analysis, Rao-Scott chi-square test, t-test, and binary logistic regression analysis, using the SAS 9.4 software. Results: Results from the multiple logistic regression analysis revealed a higher odds ratio (OR) for unmet dental care needs among those with a monthly household income below KRW 1,000,000 (OR=1.64, 95% confidence interval, 95%CI=1.39-1.92), compared to those with an income of above KRW 2,000,000. With regards to stress levels, unmet dental care needs were more prevalent among participants in the “stress moderate” (OR=1.19, 95% CI=1.06-1.33) and “stress” groups (OR=1.68 95% CI=1.48-1.92), compared to the “no stress” group. Furthermore, the OR for unmet dental care needs was significantly higher among participants in the “depression” group (OR=1.84, 95% CI=1.61-2.11) than the “no depression” group. Conclusions Higher unmet dental care needs were found among participants in the low monthly household income, stress, and depression groups. Further study is needed to analyze the association between factors and needs related to unmet dental care.

Purpose: The purpose of this study was to evaluate the validity and reliability of the Korean version of the Apathy Evaluation Scale Short Form (K AES-10) for people with dementia. Methods: Participants in this study were 198 patients with dementia resident in two hospitals in the Republic of Korea. The AES-10 was translated into Korean through the translation and adaptation of instruments process developed by the World Health Organization. This process was carried out by three bilingual nursing professionals. Validity and reliability, such as construct validity, convergent validity, Cronbach's ⍺, inter-rater reliability, and test-retest reliability, were evaluated. IBM SPSS Statistics 25.0 and AMOS 26.0 programs were used for the data analysis. Results: A uni-dimensional model was proposed in the explanatory factor analysis; a single factor accounted for 68.0% of total variances. The confirmatory factor analysis supported the validity of the Korean version of the AES-10. The scale had a Cronbach's ⍺ of .95, inter-rater reliability of .66 (p<.001), and a test-retest reliability of .81 (p<.001). Conclusion The findings show that the Korean version of the AES-10 is both valid and reliable for measuring apathy among people diagnosed with dementia in the Republic of Korea.

Purpose: To present a case of post-traumatic dislocation of the WIOL-CF® accommodating intraocular lens (IOL), composed of hydrogel material and featuring a full-optic body design, in a vitrectomized eye, highlighting considerations for surgical correction.Case summary: A 54-year-old man with a history of left-eye WIOL-CF® implantation and vitrectomy experienced sudden onset of vision deterioration in the left eye following trauma. The IOL was dislocated due to posterior capsule rupture, with the anterior capsulorhexis margin intact. The support-less circular design and material properties made it challenging to grasp the dislocated IOL in one attempt, and there was a risk of tearing when using intraocular forceps and an extrusion needle. Conclusions The case of WIOL-CF® dislocation without the capsular bag emphasizes the importance of considering the structural vulnerability and propensity for fragmentation of the IOL during removal. Adequate corneal incision size, active utilization of perfluorocarbon liquid to approximate the IOL to the anterior chamber, and gentle removal in one attempt without applying excessive force are crucial steps in the removal of a dislocated IOL.

The epithelial-mesenchymal transition (EMT) is important for embryonic development and the formation of various tissues or organs. However, EMT dysfunction in normal cells leads to diseases, such as cancer or fibrosis. During the EMT, epithelial cells are converted into more invasive and active mesenchymal cells. E-box-binding proteins, including Snail, ZEB and helix-loop-helix family members, serve as EMT-activating transcription factors. These transcription factors repress the expression of epithelial markers, for example, E-cadherin, rearrange the cytoskeleton and promote the expression of mesenchymal markers, such as vimentin, fibronectin and other EMT-activating transcription factors. Signaling pathways that induce EMT, including transforming growth factor-beta, Wnt/glycogen synthase kinase-3beta, Notch and receptor tyrosine kinase signaling pathways, interact with each other for the regulation of this process. Although the mechanism(s) underlying EMT in cancer or embryonic development have been identified, the mechanism(s) in embryonic stem cells (ESCs) remain unclear. In this review, we describe the underlying mechanisms of important EMT factors, indicating a precise role for EMT in ESCs, and characterize the relationship between EMT and ESCs.

Objectives: This study investigated the effects of mouthwashes containing cetylpyridinium chloride and zinc acetate on oral health. Methods: A total of 60 participants were included in the study. Fifty-three participants (27 and 26 participants in the experimental and control groups, respectively) were retained, excluding seven candidates who dropped out. The mouthwash used for the study was spat out after 10-15 ml of mouth-washing for 3 s in the oral cavity after breakfast, lunch, and dinner. Oral examination indices included the gingival (gingival index, PMA index), the patient hygiene performance (PHP index, Turesky plaque index), and the bad breath (BB checker, Oral chroma) indices. Five measurements were taken after 2, 4, 6, 8, and 12 weeks and compared. Results: Measurements of the gingival index showed a statistically significant difference between the experimental and the control groups after 4 weeks, and the PMA index from eight weeks (P<0.05). Measurements of the PHP and Turesky plaque indices showed a significant difference in the experimental and control groups after 4 weeks (P<0.05). Compared to the PHP index before the experiment, that of the experimental group showed a significant index decrease after 2 weeks (P<0.05). Results of measuring bad breath through a BB checker showed a statistically significant difference between the experimental and control groups after 4 weeks (P<0.05). Conclusions Oral mouthwash products containing cetylpyridinium chloride and zinc acetate relieves gingivitis, removes bacterial plaque, and reduces bad breath.

Autonomic dysfunction is a common manifestation in Guillain-Barre syndrome (GBS), but it rarely persists. We report a case involving a 22-year-old man who presented with glove-and-stocking type sensory loss, symmetric weakness, urinary distension, orthostatic hypotension, decreased perspiration, and the syndrome of inappropriate secretion of antidiuretic hormone. He was subsequently diagnosed as having GBS with autonomic failure that persisted for more than six months, despite regaining muscle strength. Orthostatic hypotension progressively improved after rehabilitation and administration of midodrine and fludrocortisone. Extensive evaluation and management should be performed in patients with GBS because severe autonomic dysfunction is a major source of disability.

PURPOSE: Although benign episodic mydriasis has been rarely reported worldwide, most of the reports so far have occurred in unilaterally. To report an unusual case of benign episodic bilateral mydriasis. CASE SUMMARY: Nineteen-year-old woman who presented with intermittent dilation of both pupils two months ago. She had difficulty on reading and doing tasks because of her visual blur. This symptom usually lasted for 1–2 hours, occurred once every 2–3 days, most frequently during stressful situations. Headaches and dizziness accompanied the eye symptoms, and her pupils were both 5 mm in a lighted room and both 7 mm in a dark room. All tests, including brain magnetic resonance imaging, showed no abnormal findings. We diagnosed her as benign episodic bilateral mydriasis. The frequency of her symptoms decreased during the university vacation period. CONCLUSIONS: In the absence of ophthalmologic or neurologic abnormalities other than headaches in patients with transient mydriasis, benign episodic mydriasis should be considered as a differential diagnosis. Although benign episodic bilateral mydriasis has a unilateral predominance, for the first time the authors report that benign episodic mydriasis may occur in both eyes during same episode.
