  • Oral cancer is a global health burden with high mortality and morbidity. Advances in treatment have failed to improve the relatively poor survival rate due to late-stage diagnosis. Early detection and screening have been shown to be effective in reducing mortality and morbidity of most common cancers. Several studies have evaluated the effectiveness of oral cancer screening programs but clear results were not obtained. This narrative commentary aimed to give a critical insight into the dilemma of oral cancer screening and to suggest recommendations for future trends. Conventional oral examination still constitutes the gold standard screening tool for potentially malignant oral lesions and cancer. Interestingly, the findings of the most lasting (15-year) randomized controlled trial on oral cancer screening using visual examination (Kerala) supported the introduction of a screening program in high-risk individuals. Several screening adjuncts exist but are still not at the introduction stage. Further research to find an appropriate adjunct reliable tool for oral cancer screening is needed. In conclusion, oral cancer fulfills most of the essential principles of cancer screening but still many points need to be clarified. Therefore, there is a striking need to establish a global consortium on oral cancer screening that will oversee research and provide recommendations for health authorities at regular intervals.

  • Purpose: This study was conducted to investigate factors affecting the dementia screening test based on the health belief model. Methods: The survey was conducted with structured questionnaires assessing the knowledge of dementia, health beliefs, self-efficacy and cue to action for dementia screening. Study participants were 156 older adults and data from 121 respondents were analyzed. Descriptive statistics, frequency percentage, chi-squared (${\chi}^2$) test, t-test and logistic regression analysis were conducted using SPSS version 23.0. Results: Factors influencing the dementia screening test were found to be gender, self-efficacy on dementia screening, and the presence of family or friends who underwent dementia screening. Older adults who were female (OR=4.92, p=.003), showed an increasing average score of self-efficacy for dementia screening (OR=2.85, p=.002), and had family members or friends who underwent dementia screening (OR=4.60, p=.003) were more likely to receive dementia screening. Conclusion: This study showed that education and programs enhancing self-efficacy associated with the dementia screening test, as well as utilizing the network of family or friends are necessary to increase the rate of dementia screening.

  • Purpose: This study is to determine knowledge about early detection and risk perception of cancer according to taking cancer screening tests in the general population. Methods: The participants were 151 people aged 40 years or older. A questionnaire consisted of knowledge about early detection (warning signs, cancer screening methods, general knowledge for early detection), cancer risk perception and history of cancer screening during past 2 years. Results: The percentages of correct answers were 64.7% in knowledge about warning signs, 73.7% in knowledge of cancer screening tests and 80.1% in general knowledge for early detection. Participants had the highest knowledge about screening methods for stomach cancer and the lowest for liver and colon cancer. The level of risk perception was medium. The participants who participated in cancer screening showed lower risk perception than those who did not. There was no significant relationship between knowledge and performance of cancer screening. The primary reason for not participating in cancer screening was patient's perception of their own health. Conclusion: These results suggest that cancer risk perception can affect the performance of cancer screening and we need to study how to handle this problem. Additionally screening programs should focus on liver cancer and colon cancer.

  • This study was aimed at preparing basic data required for establishment of a cancer screening program by examining the status of cancer screenings performed by women in a city and the factors that had an influence on cervical and breast cancers screening behavior of women. In order to find out the status of cervical and breast cancers screening and the factors having an influence on cervical and breast cancers screening behavior, 1,113 women were selected as study area and subjects by a random cluster sampling method, and the subjects were answered by questionnaires. The major results were as follows: 1. In the cases of the breast and the cervical cancers, 16.7% and 55.7% of the subjects turned out to have had one or more screenings respectively in their life-time. Also the rate of screening group of cervical and breast cancers was 16.7%, the rate of screening group of only cervical cancer was 38.9%, and the rate of non-screening group was 44.4%. 2. As to the screening pattern of cervical and breast cancer, there were significantly for age, income, occupation, married status, spouse, the factors associated with health promotion (doctor visiting, exercising), married age, number of children, and breast feeding(p〈0.05). 3. The factors associated with screening behaviors for cervical and breast cancers were age, income, occupation, married status, doctor visiting, exercising, married age, number of children, and breast feeding(p〈0.05). Based on the above-mentioned results obtained by this study, it was anticipated that this study may be playa vital role as basic data for the development and execution of cervical and breast cancers screening program for women in a community. And the analysis, done on the basis of the status of the cancer screening, of the influence factors on cervical and breast cancers screening behavior showed that for the development of a cancer screening program, the factors like age, social-economic class, married status, health promotion behavior, and reproductive characteristics should be considered.

  • Purpose: Nutrition screening is vital to ensure patients are appropriately managed in hospital. In paediatrics there is currently no universally accepted nutrition screening tool. The Nutrition Evaluation Screening Tool (NEST) was developed as an easy to use and practical screening tool for hospitalised children. We aim to evaluate compliance of the NEST and assess agreement of the NEST with the already validated nutrition screening tools, Screening Tool for Risk on Nutritional Status and Growth (STRONGkids), Screening Tool for the Assessment of Malnutrition in Paediatrics (STAMP) and the Subjective Global Nutritional Assessment (SGNA) tool. Methods: Retrospective review of 102 patient episodes at the Evelina London Children's Hospital. Electronic records were used to assess NEST compliance and to complete the nutrition tools for each patient episode. Cohen's kappa was used to determine the level of agreement between each nutrition tool. Results: There was moderate agreement between the NEST and the two screening tools, STRONGkids (κ=0.472) and STAMP (κ=0.416) for patients on initial screening at admission. 87.2% of patient episodes were NEST compliant within 24 hours of admission to hospital. Conclusion: The moderate agreement between these two already validated screening tools enhances the NEST's validity as a paediatric screening tool. The NEST had the strongest correlation with the SGNA tool compared to other screening tools. The NEST is user friendly screening tool for hospitalised children.

  • When the nature of measuring a performance variable is destructive or very expensive, it is attractive to use a surrogate variable which is highly correlated with the performance variable and less expensive to measure. In this paper, we propose rectifying screening procedures using the performance and surrogate variables. Two screening procedures are considered; a statistically-based screening procedure to reduce the current proportion of nonconforming items to a specified lower value after screening, and an economically-based screening procedure where the screening limit is determined so that the expected cost is minimized. It is assumed that the surrogate variable given the performance variable is normally distributed with known mean and standard deviation. For two screening procedures, methods of finding the optimal solutions are presented and numerical examples are also given.

  • This paper considers the problem of determining the optimum proccss mean value of the quality characteristic of interest, and the screening limit for two correlated variables under single-stage screening. In the single-stage screening, inspection is performed on two correlated variables which are correlated with the quality characteristic of interest. Model is constructed which involves selling price, production, inspection, and penalty costs. Method for finding the optimum process mean and screening limit are presented when the quality characteristic of interest and the correlated variables are assumed to be jointly normally distributed. A numerical example is presented and numerical analysis is performed to compare the proposed screening based on two screening variables with screening based on one screening variable.

  • This paper considers the problem of determining the optimal process mean and screening specification limits of a surrogate variable associated with product quality under two-stage screening procedure. In two-stage screening, the surrogate variable is inspected first to decide whether an item should be accepted, rejected or additional observations should be taken. If additional observations are required, the performance variable of interest is then observed to classify the undecided items. Assuming that the performance variable and the surrogate variable are jointly normally distributed, the optimal process mean and the screening limits are obtained by maximizing the expected profit which includes selling price, production, reprocessing, inspection and penalty costs. A numerical example is presented and numerical studies are performed to compare the proposed two-stage screening procedure with single-stage screening procedures.

  • As the demand for health screening increases, there is a need for efficient design of screening items. We build machine learning models for health screening and recommend screening items to provide personalized health care service. When offline, a synthetic data set is generated based on guidelines and clinical results from institutions, and a machine learning model for each screening item is generated. When online, the recommendation server provides a recommendation list of screening items in real time using the customer's health condition and machine learning models. As a result of the performance analysis, the accuracy of the learning model was close to 100%, and server response time was less than 1 second to serve 1,000 users simultaneously. This paper provides an adaptive and automatic recommendation in response to changes in the new screening environment.
