Objectives: The objective of this study was to determine the effect of atrial fibrillation (AF) on the risk of dementia in the Korean elderly. Methods: A 10-year retrospective cohort study was conducted using the National Health Insurance Service-Senior Cohort database. We excluded those who were under 65 years of age as of January 2006 (n=46 113), those who were diagnosed with dementia between 2002 and 2005 (n=9086), and those with a history of stroke prior to AF diagnosis (n=8392). We used a Cox proportional hazards model with a time-varying covariate to determine whether AF is associated with the risk of dementia after adjusting for potential confounders. Results: In univariable Cox regression, the hazard ratio (HR) of dementia according to AF status was 1.28 (95% confidence interval [CI], 1.23 to 1.33). After adjusting for potential confounders, AF was found to increase the risk of dementia (HR, 1.12; 95% CI, 1.07 to 1.17), Alzheimer dementia (HR, 1.12; 95% CI, 1.07 to 1.17), and vascular dementia (HR, 1.10; 95% CI, 1.03 to 1.18). In patients diagnosed with AF, the incidence of dementia was lower (HR, 0.50; 95% CI, 0.47 to 0.52) in patients who were treated with oral anticoagulants. Conclusions Investigating the potential risk factors of dementia in an aged society is important. We found a slightly higher risk of dementia in those with AF than in those without AF, and we therefore concluded that AF is a potential risk factor for dementia.

OBJECTIVE: The purpose of this study was to describe and understand self-care status of the aged diabetic patients with noncompliance after hospital discharge. METHODS: A qualitative research method was used for the study design. The participants were 15 diabetic patients aged 65 or older who had been admitted more than two times for hyperglycemia in the past 1 year in a general hospital in Daegu. Data were collected from November 1 2015 to March 1 2016 through in-depth personal interview. RESULTS: Patients' knowledge level on causes and symptoms of diabetes was low. Most participants rarely and irregularly checked blood sugar at home. They were under a lot of stress from their family. Due to old age and illness they did not have sufficient physical activity and they have had rarely regular meals. They considered the self-care education program unnecessary and there was limitations of accessibility for education. CONCLUSIONS: The aged diabetic patients who had the repeat admission did not perform self-care activities properly and had problems especially in blood glucose check, support from their family, and health education after returning home. More personalized and community-based self-management education programs will be necessary.

BACKGROUND/AIMS: The aim of this study is to evaluate defecographic and anorectal manometric findings in patients with rectocele and to identify associated pelvic floor findings. METHODS: We reviewed defecography in 90 patients (all females;mean age, 44.7 years) with rectocele, who were collected from 427 patients who underwent defecography. We also reviewed a colon transit time study, and an anorectal manometry examination. 56 healthy volunteers (mean age 36.5, female 30, male 26) were studied. RESULTS: In the patient group, the depth of rectocele was 2.92+/-0.89 cm, while in the control group, it was 1.62+/- 0.66 cm (p value < 0.001). The mean rest, squeezing, and straining centroid anorectal angle(degrees) in both groups were: 99.7+/-19.3 vs. 126.2+/-19.3; 120.4+/-15.8 vs. 111.5+/-18.9; 132.2+/-14.6 vs. 141.0+/-15.7 (p < 0.05). The mean pelvic floor descent(cm) during rest, squeezing and straining were: 5.90+/-1.26 vs. 5.08+/-1.28 (p < 0.01); 4.89+/- 1.17 vs. 3.65+/-1.13(p < 0.01); 8.61+/-1.6 vs. 7.27+/-1.39(p < 0,001). In 60 of the 90 patients with rectocele, the mean barium trap was 32.7% after defecation. The mean maximal anal resting pressure and squeezing pressure(mmHg) in both groups were: 85.8+/-25.3 vs 47.1+/-9.3(p < 0.01); 138.9+/-35.14 vs. 92.7+/-28.1(p < 0.01). The mean anal canal was opened to 2.52cm in patients with rectocele and to 2.47cm in control subjects during defecation. Associated findings were a pelvic spastic syndrome in 16, pelvic descent syndrome in 37, rectoanal intussusception in 37 and rectal prolapse in 4 of the patients. Colon transit time was more prolonged in the patient group than the control group. CONCLUSIONS: Rectocele may be associated with various pelvic floor diseases. Careful preoperative investigations are important before surgical treatment of rectocele.
