Ischemic stroke and Alzheimer's disease (AD) are representative geriatric diseases with a rapidly increasing prevalence worldwide. Recent studies have reported an association between ischemic stroke neuropathology and AD neuropathology. Ischemic stroke shares some similar characteristics with AD, such as glia activation-induced neuroinflammation, amyloid beta accumulation, and neuronal cell loss, as well as some common risk factors with AD progression. Although there are considerable similarities in neuropathology between ischemic stroke and AD, no studies have ever compared specific genetic changes of brain cortex between ischemic stroke and AD. Therefore, in this study, I compared the cerebral cortex transcriptome profile of 5xFAD mice, an AD mouse model, with those of middle cerebral artery occlusion (MCAO) mice, an ischemic stroke mouse model. The data showed that the expression of many genes with important functional implications in MCAO mouse brain cortex were related to synaptic dysfunction and neuronal cell death in 5xFAD mouse model. In addition, changes in various protein-coding RNAs involved in synaptic plasticity, amyloid beta accumulation, neurogenesis, neuronal differentiation, glial activation, inflammation and neurite outgrowth were observed. The findings could serve as an important basis for further studies to elucidate the pathophysiology of AD in patients with ischemic stroke.

This study examined two differences in physical and psychological recovery patterns after surgery in the elderly. The sample consisted of 40 patients with abdominal surgery In five large hospitals in Seoul. The data for this study were collected from Apr. 20 to Nov. 26 by structured questionnaire, chart review and call. Physical recovery was assessed by ADL, a Cantril Ladder Scale and a Visual Analogue Scale. Psychological recovery was measured by the Geriatric depression Scale and a Cantril Ladder Scale. The data were analyzed using frequency, percentage, Pearson Correlation Coefficient, and MANOVA by SPSS/WIN. The result are as follows : 1. Physical recovery indicated significant improvement over time with the exception of ADL(F=.812 p=.449). Perceived physical health were significantly improved(F=6.189 p=.004). Pain & discomfort was significantly decreased(F=3.927 p=.025). 2. Perceived psychological health was significantly improved over time(F=20.648 p=.000), but depression showed no statistical significance improvement over time(F=1.393 p=.256). 3. There were no significant effects of sex, age, complication and combined chronic diseases on physical and psychological recovery patterns. 4. There were significant correlations between operation time and pain(r=-.331 p=.020), recovery time and perceived psychological health(r=-.320 p=.024), recovery time and pain(r=.404 p=.005). There were significant correlations between admision period and ADL(r=-.418 p=.004), perceived physical health(r=-.354 p=.014), depression(r=.280 p=.042), and perceived psychological health(r=-.447 p=.002). BRAS showed significant correlation with ADL(r=-.458 p=.002). 5. With an increase in the degree of perceived health(physical and psychological), ADL was significantly increased. With an increased in the degree of depression and pain, ADL and perceived health(physical and psychological) were significantly decreased. In conclusion, the elderly patient recovered significantly over time with the exception of ADL and depression. It these we suggested to considered when planning care for elderly patients.

Background: The risk factors of nocturia in older adults remain unclear. We aimed to investigate factors associated with nocturia using the National Health and Nutrition Examination Survey (NHANES) data. Methods: Among 40,790 participants, 4,698 participants aged ${\geq}65$ years were included from the NHANES dataset between 2005 and 2012. A multivariate logistic regression analysis was performed to determine the odds ratio (OR) for nocturia. A subgroup analysis was conducted based on sex and underlying diseases. Results: In the multivariate logistic regression model, obesity (OR, 1.46; 95% confidence interval [CI], 1.28-1.68), hypertension (OR, 1.28; 95% CI, 1.07-1.52), and diabetes mellitus (DM) (OR, 1.27; 95% CI, 1.11-1.45) were significantly associated with nocturia. These factors were associated with nocturia regardless of sex. In a subgroup of participants with hypertension, obesity (OR, 1.44; 95% CI, 1.25-1.67) and DM (OR, 1.26; 95% CI, 1.09-1.45) were associated with nocturia. In the additional analysis on patients with DM, nocturia was associated with obesity (OR, 1.33; 95% CI, 1.06-1.67) and duration of DM (OR, 1.02; 95% CI, 1.01-1.03). Conclusion: This study demonstrated that hypertension, DM, and obesity were significantly associated with the prevalence of nocturia in older adult patients regardless of sex. In particular, obesity was associated with nocturia in every subgroup analysis.

Background: The number of elderly people with comorbidities who experience dysphagia associated with geriatric disorders, such as stroke, Parkinson's disease, and Alzheimer's dementia, is increasing. Consequently, the demand for long-term prescriptions of powdered medications is expected to rise. Most patients procure repackaged prescription medications from pharmacies; however, the guidelines regarding their expiration dates are unclear. Objectives: The aim of this study was to assess awareness among adults regarding the expiration dates and drug stability issues associated with repackaged prescription medications, including powdered medications. Methods: A questionnaire with 16 components was designed and distributed online (August 1-September 1, 2019) to adults aged 19 years or older. Statistical analyses, including descriptive analysis and chi-square test, were conducted on the obtained data. A p-value <0.05 was considered significant. Results: Data from 254 respondents were analyzed; 191 (75.20%) respondents worked in non-healthcare-related fields. A significant number of healthcare workers recognized the stability issues associated with powdered medications (p<0.001). However, a large proportion of healthcare workers were not aware of the expiration dates (p>0.05). Conclusions: More than half of the total respondents, including healthcare workers, were not familiar with the appropriate expiration dates of repackaged prescription medications. The establishment of evidence-based guidelines regarding drug expiration dates and the dissemination of awareness among patients are required. Furthermore, clinical practices including repackaging or pulverizing medications for long-term prescriptions should be avoided owing to the associated drug stability issues.

Purpose : This study examined the effect of locomotive syndrome on stress index and lifestyle patterns among elderly Koreans aged 65 years and older, and analyzed its correlation with stress index and lifestyle patterns. The purpose of this study was to provide basic data for the management and prevention of locomotive syndrome in the elderly. Methods : Using the "25-Question Geriatric Locomotive Function Scale (GLFS-25)", the study evaluated locomotive syndrome in 123 elderly Koreans aged 65 years and older. Of them, 85 patients were assigned to the locomotive syndrome group and 38 patients were assigned to the normal group. The questionnaire measured and investigated the participants' stress index and lifestyle patterns. Statistical analysis was performed using SPSS 22.0 ver. Results : Results showed the locomotive syndrome group displayed a higher stress index than the normal group, with a statistically significant difference between the two groups. The group also scored lower in the lifestyle pattern survey than the normal group did, with a statistically significant difference in high-intensity work performance ratio and average daily performance time between them. The GLFS-25 score showed a significant positive correlation with the stress index and sitting and lying down time, and a significant negative correlation with medium-intensity working time, walking, and cycling time. Conclusion : In conclusion, Locomotive syndrome in elderly Koreans is closely related to stress and lifestyle patterns, especially high-intensity work. We recommend active prevention and management of locomotive syndrome and further research into the effects of various lifestyle factors on the illness.

With increasing global life expectancy, the significance of geriatric assessment parameters has increased. Sarcopenia is a crucial assessment parameter and is defined as the age-related loss of muscle mass and strength. Sarcopenia is widely acknowledged as a risk factor for postoperative complications in diverse advanced malignancies and has a detrimental effect on the long-term prognosis. While most studies have primarily concentrated on the correlation between sarcopenia and advanced cancer, more recent investigations have focused on the relationship between sarcopenia and early-stage cancer. Endoscopic submucosal dissection (ESD), which is less invasive than surgical intervention, is extensively employed in the management of early-stage cancer, although it is associated with complications such as bleeding and perforation. In recent years, several reports have revealed the adverse consequences of sarcopenia in patients with early-stage cancer undergoing ESD. This literature review briefly summarizes the recent studies on the association between sarcopenia and ESD.

Objectives: Cognitive impairment in restless legs syndrome (RLS) patients can be affected by sleep deprivation, anxiety and depression, which are common in RLS. The objective of this study is to investigate relationship between cognitive impairment and RLS in the non-medicated Korean elderly with controlling for psychiatric conditions. Method: The study sample for this study comprised 25 non-medicated Korean elderly RLS patients and 50 age-, sex-, and education- matched controls. All subjects were evaluated with comprehensive cognitive function assessment tools- including the Korean version of Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet (CERAD-K), severe cognitive impairment rating scale (SCIRS), frontal assessment battery (FAB), and clock drawing test (CLOX). Sleep quality and depression were also assessed with Pittsburgh sleep quality index (PSQI) and geriatric depression scale (GDS). Results: PSQI and GDS score showed no difference between RLS and control group. There was no significant difference between two groups in nearly all the cognitive function except in constructional recognition test, in which subjects with RLS showed lower performance than control group (t=-2.384, p=0.02). Subjects with depression ($GDS{\geq}10$) showed significant cognitive impairment compared to control in verbal fluency, Korean version of Mini Mental Status Examination in the CERAD-K (MMSE-KC), word list memory, trail making test, and frontal assessment battery (FAB). In contrast, no difference was observed between subjects who have low sleep quality (PSQI>5) and control group. Conclusions: At the exclusion of the impact of insomnia and depression, cognitive function was found to be relatively preserved in RLS patients compared to control. Impairment of visual recognition in RLS patients can be explained in terms of dopaminergic dysfunction in RLS.

Purpose : The purpose of this study was to find out cognitive function of the patients with subjective memory complaint. Material and Methods : From March 1st 2005 to May 31st 2009, 155 normal individuals without any medical illness who visited Yeungnam University Hospital to undergo medical checkup with neurocognitive test was enrolled, and checked by using Cognitive Assessment & Reference Diagnostic System. Results : 107 of the patients had normal cognitive function, 21 patients (about 15%) were diagnosed with dementia, and 10 patients (about 7%) were diagnosed with considerable psychiatric illness, such as depression, anxiety disorder, adjustment disorder. In amnesia, agnosia, aphasia, attention, calculation, dysexecution, Dementia group and Psychiatric illness group has worse score than Normal individuals group. But, in apraxia, Dementia group has worse score than Psychiatric illness group and Normal individual group. Conclusion : Because the patients with subjective memory complaint can be diagnosed as any psychiatric illness as well as dementia, sensitive screening test and early psychiatric approach is needed.

Purpose: This study analyzes occupational therapy interventions to improve activities of daily living (ADL) in dementia patients and the instruments used to verify their effects through a systematic review and attempts to use the results as preliminary data in selecting further interventions and instruments. Method: The databases searched included NDSL, DBpia, RISS, KISS and National Assembly Library with search words including 'Alzheimer's disease', 'Alzheimer', 'daily living' and 'ADL.' The subjects of analysis were a total of 7 studies, and a frequency analysis was used for the usage count of the interventions used in each study. In order to provide evidence, PICO Method was used for sorting. Result: As a result of this study, there were 7 occupational therapy interventions applied to improve ADL in dementia patients, which were used 7 times total. As for the instruments used to validate the effects of the interventions for the ADL, it turned out that '3 studies used AMPS (42.9%),' which was the most, followed by 'Allen Cognitive Level Screen' (ACLS) and Functional Independence Measure' (FIM), respectively used in 2 studies (28.6%); and 'Modified Barthel Index' (MBI) and 'Philadelphia Geriatric Center IADL' (PGC IADL), respectively used in 1 study. Regarding the qualitative level of evidence, it turned out that 4 studies were Level III (57.1%), followed by 2 studies at Level IV (28.6%) and 1 study at Level I (14.3%). Conclusion: This study suggested the kinds and frequencies of usage of the interventions and instruments of occupational therapy for the improvement of ADL in dementia patients, and the studies of evidence were presented by the PICO Method. It is judged that the results of this study can be used as preliminary data in selecting interventions and instruments to improve the ADL in dementia patients. In the future, studies should be carried out on the ADL in other areas related to dementia.

Delirium is among the most common mental disorders encountered in patients with a temporary cognitive impairment such as consciousness disorder, attention disorder, and poor speech, particularly among those who are older. Delirium is distressing for patients and families, can interfere with the management of symptoms such as pain, and is associated with increased elderly mortality. The purpose of this paper is to generate useful clinical knowledge that can be used to distinguish the outcomes of patients with delirium in long-term care facilities. For this purpose, we extracted the clinical classification knowledge associated with delirium using a local covering rule acquisition approach with the rough lower approximation region. The clinical applicability of the proposed method was verified using data collected from a prospective cohort study. From the results of this study, we found six useful clinical pieces of evidence that the duration of delirium could more than 12 days. Also, we confirmed eight factors such as BMI, Charlson Comorbidity Index, hospitalization path, nutrition deficiency, infection, sleep disturbance, bed scores, and diaper use are important in distinguishing the outcomes of delirium patients. The classification performance of the proposed method was verified by comparison with three benchmarking models, ANN, SVM with RBF kernel, and Random Forest, using a statistical five-fold cross-validation method. The proposed method showed an improved average performance of 0.6% and 2.7% in both accuracy and AUC criteria when compared with the SVM model with the highest classification performance of the three models respectively.
