Objectives: The purpose of this study was to identify the effects of general and oral health status on dementia. Methods: Questionnaires were used for the KDSQ-C (Korean Dementia Screening Questionnaires-Cognition) and to investigate the oral health status of the participants. An independent t-test was conducted to analyze the differences between general health and oral health status depending on the normal and suspected dementia groups. Logistic regression analysis was performed to assess the effects of general and oral health status on dementia. Results: Regarding the health status of the subjects assessed by the KDSQ-C, the higher the current health status and the higher the exercise status, the lower was the dementia level (p<0.05). During the assessment of oral health conditions in KDSQ-C subjects, dementia was more suspected in subjects with dental decay and periodontal disease than in those without dental decay (p<0.05). Conclusions: Dementia has been confirmed to be closely related to general and oral health conditions. Therefore, oral health-related programs are essential for dementia prevention programs. Since dental hygienists are best suited for providing oral care to older adults with dementia, it is considered essential to reflect their occupation in future national policies.
In this study, the authors surveyed the dietary habits of all elementary school students registered with the Busan Metropolitan City Office of Education using an online questionnaire called the Dietary Screening Test (DST). The DST consists of 36 items, and these were divided into 5 factors: life rhythm, meal quality, eating development, eating temperament characteristics, and eating habit characteristics. Data were collected from 153,017 students attending 304 schools in Busan, and the responses of 4,020 were included in the analysis. The study was undertaken to document growth and development and diagnose nutrition and dietary problems to provide basic data for the development of customized nutrition education and counseling programs. Results showed that 13.5% and 14.3% of participants were classified as overweight or required weight management for obesity, respectively; 6.7% were underweight. Additionally, 37.0% and 9.5% of children required parental attention at bedtime and sleeping hours, and 14.2% ate too quickly or too slowly. Furthermore, food group consumptions were unbalanced, 25.0% and 64.4% of participants ate grains and protein less than twice a day, respectively, and 72.3% and 74.5% ate kimchi and vegetables less than twice a day, respectively. In contrast, 28.8% of respondents consumed sweet snacks daily or 5~6 times weekly. These findings highlight the need for a standardized school nutrition counseling manual and individually customized nutrition counseling programs to address the nutrition and dietary problems of elementary school students in Busan.

Aggregates of disease-causing proteins dysregulate cellular functions, thereby causing neuronal cell loss in diverse neurodegenerative diseases. Although many in vitro or in vivo studies of protein aggregate inhibitors have been performed, a therapeutic strategy to control aggregate toxicity has not been earnestly pursued, partly due to the limitations of available aggregate models. In this study, we established a tetracycline (Tet)-inducible nuclear aggregate (${\beta}23$) expression model to screen potential lead compounds inhibiting ${\beta}23$-induced toxicity. High-throughput screening identified several natural compounds as nuclear ${\beta}23$ inhibitors, including peucedanocoumarin III (PCIII). Interestingly, PCIII accelerates disaggregation and proteasomal clearance of both nuclear and cytosolic ${\beta}23$ aggregates and protects SH-SY5Y cells from toxicity induced by ${\beta}23$ expression. Of translational relevance, PCIII disassembled fibrils and enhanced clearance of cytosolic and nuclear protein aggregates in cellular models of huntingtin and ${\alpha}$-synuclein aggregation. Moreover, cellular toxicity was diminished with PCIII treatment for polyglutamine (PolyQ)-huntingtin expression and ${\alpha}$-synuclein expression in conjunction with 6-hydroxydopamine (6-OHDA) treatment. Importantly, PCIII not only inhibited ${\alpha}$-synuclein aggregation but also disaggregated preformed ${\alpha}$-synuclein fibrils in vitro. Taken together, our results suggest that a Tet-Off ${\beta}23$ cell model could serve as a robust platform for screening effective lead compounds inhibiting nuclear or cytosolic protein aggregates. Brain-permeable PCIII or its derivatives could be beneficial for eliminating established protein aggregates.

Background: Colon cancer screening (CRCS) uptake is markedly affected by public awareness of the disease. This study was conducted to assess levels of knowledge of CRC, to explore the pattern of CRCS uptake and identify possible barriers to screening among Saudis older than 50 years of age and primary care providers (PCPs) in Al Hassa region, Saudi Arabia. Materials and Methods: This cross-sectional study was conducted in randomly selected primary health care (PHC) centers, 884 Saudis and 39 PCPs being enrolled for data collection. Structured interviews were conducted to obtain information regarding socio-demographic characteristics, personal information relevant to CRC, awareness about early signs/symptoms and risk factors, and barriers to CRCS. Also, a self- administered data collection form was used to assess barriers to CRCS from the physicians' perspectives. Results: More than 66% of participants were lacking knowledge about CRC. Participants with higher educational levels, having ever heard about CRC, and having relatives with CRC had a significantly higher awareness of the disease. The rate of reported CRCS was low (8.6%). After conducting a logistic regression analysis, it was observed that female gender (OR=0.28; 95% CI=0.14-0.57; P=0.001), being unmarried (OR=0.11; 95% CI=0.10-0.23; P=0.001), lower levels of education (OR=0.36; 95% CI=0.16-0.82; P=0.015), and having no relatives with CRC (OR=0.30; 95% CI=0.17-0.56; P=0.001) were significantly associated with a lower CRCS uptake. There was a significant difference between most of the perceived barriers to CRCS and gender. Exploratory factor analysis showed that personal fear (especially fear of the screening results and shyness) was the major factor that hindered CRCS with high loading Eigen value of 2.951, explaining 34.8% of the barriers of the included sample toward utilization of CRCS, followed by lack of awareness of both person and providers (high Eigen value of 2.132, and explaining 23.7% of the barriers). The most frequently cited barriers to CRCS from the physicians' perspectives were lack of public awareness, lack of symptoms and signs, and fear of painful procedures. Conclusions: Poor levels of knowledge about CRC were found among older Saudis attending PHC centers in Al Hassa, Saudi Arabia. It is crucial to implement an organized national screening program in Saudi Arabia to increase public awareness.
This study intended to identify the factors of breast and cervical cancer screening behaviors in married female immigrants and provide information for the development of intervention programs to promote the behaviors. Pender's Health Promotion Model was the conceptual framework of this study. The subjects of this study were 157 female immigrants living in Daegu and Gyeongbuk area. It was found that 33.1% of subjects had mammography, 22.9% of them did breast self-examination, and 51% of them had cervical cancer screening test. The breast cancer screening behavior increased 1.25 times as the score of social support increased one point, 1.13 times as the score of perceived benefit increased one point, 3.58 times when the subjects had experiences of breast and cervical cancer education, and 1.24 times as the score of action plan increased one point. The cervical cancer screening behavior increased 2.89 times when the subjects had experiences of breast and cervical cancer education, and 1.23 times as the score of social support increased one point. However, the cervical cancer screening behavior decreased 0.82 times as the score of perceived barriers increased one point.
Population screening of newborns is an extremely important and informative diagnostic approach that allows early identification of babies who are predisposed to the development of a number of serious diseases. Some of these diseases are known and have effective treatment methods. Neonatal screening enables the early diagnosis and subsequent timely initiation of therapy. This helps to prevent serious complications and reduce the percentage of disability and deaths among newborns and young children. Primary immunodeficiency diseases and primary immunodeficiency syndrome (PIDS) are a heterogeneous group of diseases and conditions based on impaired immune system function associated with developmental defects and characterized by various combinations of recurrent infections, development of autoimmune and lymphoproliferative syndromes (genetic defects in apoptosis, gene mutation Fas receptor or ligand), granulomatous process, and malignant neoplasms. Most of these diseases manifest in infancy and lead to serious illness, disability, and high mortality rates. Until recently, it was impossible to identify children with PIDS before the onset of the first clinical symptoms, which are usually accompanied by complications in the form of severe coinfections of a viral-bacterial-fungal etiology. Modern advances in medical laboratory technology have allowed the identification of children with severe PIDS, manifested by T- and/or B-cell lymphopenia and other disorders of the immune system. This review discusses the main existing strategies and directions used in PIDS screening programs for newborns, including approaches to screening based on excision of T-cell receptors and kappa-recombination excision circles, as well as the potential role and place of next-generation sequencing technology to increase the diagnostic accuracy of these diseases.
Objective : The objective of this study was to present the components of frailty by organizing the definitions of frail elderly and analyzing the tools used to screen them. Methods : This study searched for articles at involved frailty screening assessments in the elderly. Databases including CINAHL, Embase, Medline Complete, and PubMed were searched. The search terms were "assess" AND "frailty" AND "screening" AND ("frail elderly" OR "elderly"). Results : A total of 539 articles were identified by the search and 11 articles were selected. Frailty occurs due to the depressed function of multidimensional factors, and a frail elderly person is defined as one at high risk of health degeneration, functional impairment, and occurrence of disability, and having a high level of threat to life. Seven tools were selected from 11 articles. The most frequently used tool was the frailty phenotype, which was used in five articles (45.4%). The identified components of frailty were physical, activity participation, nutrition, psychological, social, overall health, and age. Conclusion : The results confirmed the definition and components of frailty. This study is expected to contribute to the future development of standardized evaluation tools for screening frail elderly individuals and intervention programs for the management of the frail elderly.
Purpose: Screening of delirium using delirium assessment tools could promote delirium detection, however, there is lack of report about regular delirium assessment in Korea. This study was intended to describe the prevalence and related risk factors of delirium in intensive care unit (ICU). Methods: The Confusion Assessment Method for the ICU (CAM-ICU) data which were evaluated by nurses in ICUs was obtained through retrospective chart review. Data were analyzed using descriptive statistics, Chi-square test, t-test, Mann-Whitney U test, and stepwise logistic regression. Results: Delirium was evaluated in 125 patients. The incidence rate of delirium was 27.2% with a high prevalence of hypoactive delirium compared to hyperactive delirium (61.8 vs. 38.2%). Those with delirium were older, had hypertension, stayed longer in hospital, receiving ventilator support, had more number of catheters, had low serum protein and albumin level. Delirium incidence also varied according to diagnosis. Age, diagnosis of gastrointestinal disease, and application of ventilator were the significant risk factors for the incidence of delirium. Conclusion: Routine delirium screening is important for early detection of delirium. Identification of high-risk group and running delirium prevention programs could improve early recognition of delirium in ICU.
Recently, there is a worldwide concern that a great number of man-made chemicals have a hormone-like action both in humans and in animals. EPA and OECD are developing screening programs using validated test systems to determine whether certain substances may have an effect on humans. In the present study, the establishment of in vivo short-term test system for pubertal female assay with thyroid to detect endocrine disrupting chemicals was tried using a model substance, methoxychlor (MC), a chlorinated hydrocarbon insencticide. Forty female rats were assigned to four groups. MC was administered at dose levels of 0, 8, 40 and 200mg/kg by gavage to female rats from day 21 post partum to the completion of vaginal opening. We evaluated body weight change, age at vaginal opening, onset of estrous cyclicity, age at first esturs, ovary weight, and serum concentrations of thyroxine and thyroid stimulating hormone in female rats. The age at vaginal opening of females receiving 40 200mg/kg was significantly younger than control. The onset of estrus cyclicity and age at first estrus of females receiving 200mg/kg was also younger than controls. There was no effect of treatment on body weight, ovary weight, and hormone concentration. Based on these results, it can be concluded that application of MC at dose level of 40mg/kg affects the vaginal opening and application of MC at dose level of 200mg/kg accelerates the vaginal opening and the onset of estrus cylicity.

Screening with low-dose spiral computed tomography (LDCT) has been shown to reduce lung cancer mortality by about 20% when compared to standard chest radiography. One of the problems arising from screening programs is that large amounts of CT image data must be interpreted by radiologists. To solve this problem, automated detection of pulmonary nodules is necessary; however, this is a challenging task because of the high number of false positive results. Here we demonstrate detection of pulmonary nodules using six off-the-shelf convolutional neural network (CNN) models after modification of the input/output layers and end-to-end training based on publicly databases for comparative evaluation. We used the well-known CNN models, LeNet-5, VGG-16, GoogLeNet Inception V3, ResNet-152, DensNet-201, and NASNet. Most of the CNN models provided superior results to those of obtained using customized CNN models. It is more desirable to modify the proven off-the-shelf network model than to customize the network model to detect the pulmonary nodules.
