Purpose: The aim of this study was to establish an association between grip strength and gait variability in the elderly. Methods: The participants in this experiment (n = 20) were aged 65 or older. Power grip and lateral pinch forces were obtained in grip strength tests, and spatiotemporal gait parameters were collected from IMU sensors during 6 min actual walking to test the gait of participants. The collected gait parameters were converted to coefficient of variation (CV) values. To confirm the association between grip strength and gait variability, a partial correlation analysis was conducted in which height, weight, and gait speed were input as controlling variables. Results: Grip power showed a significant negative correlation with the stride length CV (r = -0.52), and the lateral pinch force showed a significant negative correlation with the stance CV (r = -0.65) and swing CV (r = -0.63). Conclusion: This study reveals that gait variability decreases as grip strength increases, although height, weight, and gait speed were controlled. Thus, grip strength testing, a simple aging evaluation method, can help identify unstable gait in older adults at risk of falling, and grip strength can be utilized as a non-invasive measurement method for frailty management and prevention.

Purpose: Influenza is the most common seasonal infectious disease that causes permanent social, economic, and medical problems worldwide. Therefore, the most effective way to prevent influenza is through vaccines. The aim of this study is to identify the influence of factors that determine the refusal of influenza vaccine among three subjects groups. Materials and Methods: A survey was conducted amongst the three high-risk groups in 2018-2019 (Moscow, Russia). The survey involved 1,620 parents and pregnant women (group 1), 324 doctors (group 2), and 433 students (group 3). Poor vaccine uptake was observed among respondents in all three groups. Results: According to the survey results, only 22.2% of children and 13.8% of adults were vaccinated against influenza. Group 2 showed increased rates with 36.7% of vaccinated adults and 58.7% of children. The lowest adherence to annual vaccinations was recorded in group 3 (only 17.3%). There is also a negative correlation between adherence to vaccination and smoking (-0.66), unhealthy diet (-0.73), poor oral hygiene (-0.61), and insufficient awareness of the need for influenza vaccine as well (-0.81). Conclusion: Thus, a general lack of vaccination awareness has a fundamental role in forming a negative attitude toward influenza vaccine. It is necessary to conduct research to promote vaccination against influenza to improve vaccine uptake among high-risk groups, particularly students.

목적: 자궁내막암의 치료 후 루틴 추적관찰로써의 FDG-PET/ET의 유용성에 대해 알아보고자 하였다. 대상 및 방법: 자궁내막암으로 치료 받은 환자 중 2004년 1월 1일부터 2008년 1월 31일 사이에 FDG-PET/CT를 시행한 101명의 환자(25-79세, 평균 50.6세)를 대상으로 하였다. 모든 환자에서 종양표지 자와 다른 영상의학적 검사(CT, MR)에 대해서도 함께 검토하였다. FDG-PET/CT상 국소 FDG 섭취를 보인 병변을 benign, equivocal, malignant로 분류하였고, equivocal과 maliganat 병변에 대하여 조직학적 혹은 임상적으로 재발유무를 판정하였다. 결과: FDG-PET/CT상 강한 섭취를 보인 경우는 19명의 30개의 병변이었다. Malignant 섭취를 보인 환자는 14명이었고, 이중 11예가 재발로 확인되었다. Equivocal 병변을 보인 환자는 5명 이었고, 이중 1예가 재발로 확인되었다. 위음성을 보인 경우는 2예가 있었고, 모두 복강내 암종증 환자로 진단되었다. 이상의 결과를 종합하였을 때, 자궁내막암의 치료 후 재발의 평가에 대한 전반적인 결과는 예민도 86 %,특이도 92 %, 양성 예측도 63 %, 음성예측도 98 %, 그리고 정확도는 91 %였다. 결론: 자궁내막암의 치료 후 루틴 추적관찰로써 FDG-PET/ET를 시행할 경우 높은 예민도, 특이도로 재발의 진단에 도움이 될 뿐만 아니라 높은 음성 예측도로 인하여 FDG-PET/CT상 음성인 경우 불필요한 추가 검사를 피할 수 있을 것으로 기대된다.

Purpose : To investigate the relationship between breathing pattern disorder and joint position error (JPE) in patients with chronic low back pain (CLBP). Methods : Thirty nine patients with CLBP participated. End-tidal $CO_2$ and respiration rate (RR) were measured using a capnography. Breathing-hold time (BHT) and Nijmegen Questionnaire (NQ) were investigated. Thoracic excursion was measured with a cloth tape measurement technique. Joint position error were measured using a small laser point mounted on a lightweight headband. they were asked to relocate the head, after the neck movement on the horizontal plane. Pearson 's test was used for correlation analysis between respiratory variables and JPE in patients with CLBP. Independent t-test was used to verify the difference between thoracic and diaphragm breathing pattern in patients with CLBP. The significance level was set at 0.05. Results : There was a significant correlation between JPE (LR) and JPE (RR, EX) (r=.639, r=.813) (p<.001) and a low negative correlation with end-tidal $CO_2$ (r=-.357) (p<.05). There was a significant correlation between RR and JPE (EX) (r=.750) (p<.001). There was a low correlation between JPE (EX) and NQ (r=.333) (p<.05). There was a somewhat high negative correlation between NQ and thoracic excursion (r=-.528) (p<.001). There was a somewhat high negative correlation between thoracic excursion and JPE (LR, RR, EX) (r=-.470, r=-.484, r=-.602) (p<.001). There were no significant differences in the RR, BHT, NQ, and thoracic excursion between the thoracic and diaphragmatic breathing (p>.05). There was a significant difference in the JPE (EX), end - tidal $CO_2$, and VAS values between the thoracic and diaphragm breathing (p<.05). Conclusion : There was a correlation between JPE (EX) and NQ in patients with CLBP, and correlation between thoracic excursion and JPE (LR, RR, EX) and NQ. There was a significant difference in the JPE (EX), end-tidal $CO_2$ level, and VAS value in the comparison of thoracic breathing and diaphragm breathing. The results showed that breathing patterns and JPE were related to each other.

Purpose : The purpose of this study is to investigate the effects of sleep duration on stress and depression in college students. The results obtained will be used as a foundational framework for fostering a healthy sleep culture among college students and for formulating measures to improve the quality of their sleep. Ultimately, we intend to produce a publicity and educational material. Methods : For this study, a survey involving 100 college students was conducted, after which data based on a final total of 95 respondents were analyzed. The information on stress and depression were first analyzed in terms of general characteristics and then organized based on the data collected to investigate the effects of sleep duration on stress and depression. The participants were divided into the following groups: "less than 6 hours," "6 to 7 hours," and "7 to 8 hours." BEPSI-K (Brief encounter psychosocial instrument-Korean) was used for stress evaluation, while K-CESD-R (Korean version of center for epidemiologic studies depression scale-revised) was utilized for depression evaluation. Results : First, according to sleep duration, the BEPSI-K scores showed a statistically significant difference in each group (p<.01). In the post-hoc test, there was a difference among the "less than 6 hours" group, the "7 to 8 hours" group. A statistically significant difference was noted (p<.01). In addition, sleep duration had a statistically significant effect on the negative (-) direction of the BEPSI-K (p<.01). Second, the K-CESD-R score according to sleep duration showed a statistically significant difference in each group (p<.01). Notably, in the post-hoc test, the "less than 6 hours" group differed from the "6 to 7 hours" group, "7 to 8 hours" group. A statistically significant difference was noted (p<.01). In addition, sleep duration had a statistically significant effect on the negative (-) direction of the K-CESD-R (p<.01). Third, for the correlation between sleep duration and stress and depression, a negative (-) correlation was found between sleep duration and BEPSI-K and K-CESD-R. Meanwhile, a positive (+) correlation was found between BEPSI-K and K-CESD-R. Conclusion : Based on the findings of this study, the sleep duration of college students has an effect on stress and depression. The results of this study can be used as a foundational framework in formulating a plan for improving the quality of sleep of college students.

Recently, interferon gamma releasing assay has been recommended to compensate the tuberculin skin test (TST) for screening for latent tuberculosis infection (LTBI). Although it improved the detection of LTBI before treatment with tumor necrosis factor blocker, its application to immune suppressed patients is limited. We report a case of peritoneal tuberculosis (TB) developed in a patient who tested positive for TST and QuantiFERON-TB Gold (QFT-G) before infliximab therapy, to emphasize the importance of monitoring during treatment. A 52-year-old woman presented with abdominal distension. She had been diagnosed with seropositive rheumatoid arthritis six years ago. She had started taking infliximab six months ago. All screening tests for TB were performed and the results of all were negative. At admission, the results of repeated TST and QFT-G tests were positive. Histopathological examination confirmed peritoneal TB. The patient started anti-TB therapy and the symptoms were relieved.

Purpose : The purposes of this study were to investigate the age-related difference in balance ability in the elderly over 65 years and to verify the clinical usefulness of the functional reach test (FRT) for balance evaluation of the elderly through the sensory organization test (SOT). Methods : The subjects were forty-six community dwelling elderly people over 65 years old in order to verify the correlation of balance measures and to compare the balance ability. Balance was measured using the FRT and the six sub-equilibrium scores and the composite equilibrium score of the SOT. Pearson's product correlation coefficient was used to evaluate the relationships among these measurements of balance. Results : There was a significant difference in functional reach by age in the elderly (p<.01). There was a significant negative correlation between the FRT and the age of the elderly (r=-.396, p<.01). There was also significant high positive correlation between the FRT and the eye closed sway surface (EC/SS) (r=.789, p<.01), and composite equilibrium score (r=.548, p<.01) of the SOT. Conclusion : Thus, it is possible to use the FRT as a quantitative measure of balance, rather than the SOT, which is more expensive and complicated to evaluate elderly people. According to the results of this study, the use of the FRT is required clinically to objectively measure the balance of elderly people in the future.

Purpose: The aim of this retrospective cross-sectional study was to evaluate whether salivary findings of active matrix-metalloproteinase 8 (aMMP-8) chairside (point of care; POC) tests were associated with periodontal risk assessment parameters in patients receiving supportive periodontal therapy (SPT). Methods: A total of 125 patients receiving regular SPT were included, and their records were examined. The following inclusion criteria were used: a diagnosis of chronic periodontitis, at least 1 non-surgical periodontal treatment (scaling and root planning) with following regular SPT (minimum once a year), at least 6 remaining teeth, and clinical and aMMP-8 findings that were obtained at the same appointment. In addition to anamnestic factors (e.g., smoking and diabetes), oral hygiene indices (modified sulcus bleeding index [mSBI] and approximal plaque index), periodontal probing depth simultaneously with bleeding on probing, and dental findings (number of decayed, missing, and filled teeth) were recorded. Salivary aMMP-8 levels were tested using a commercial POC test system (Periomarker, Hager & Werken, Duisburg, Germany). Statistical analysis was performed using the t-test, Mann-Whitney U test, Fisher's exact test, and ${\chi}^2$ test, as appropriate (P<0.05). Results: Only the mSBI was significantly associated with positive salivary aMMP-8 findings (aMMP-8 positive: $27.8%{\pm}20.9%$ vs. aMMP-8 negative: $18.0%{\pm}14.5%$; P=0.017). No significant associations were found between aMMP-8 and smoking, diabetes, periodontal parameters, or parameters related to the maintenance interval (P>0.05). Conclusions: Salivary aMMP-8 chairside findings were not associated with common parameters used for periodontal risk assessment in patients receiving SPT. The diagnostic benefit of POC salivary aMMP-8 testing in risk assessment and maintenance interval adjustment during SPT remains unclear.

Purpose: This study was a systematic review and meta-analysis designed to investigate effects of psychoeducational intervention for cancer survivors. Methods: Ten databases were searched. Two reviewers independently performed the selection of the studies, data extraction and assessment. The risk of bias was assessed using Cochrane Collaboration's tool. To estimate the effect size, meta-analysis of the studies was performed using Comprehensive Meta-Analysis and RevMan programs. Results: Of 18,781 publications identified, 35 met inclusion criteria, and 25 studies were used to estimate effect size of psychoeducational intervention. Effect sizes (standardized mean difference [SMD]) were heterogeneous and random effects models were used in the analyses. Psychoeducational intervention was effective for quality of life (n=2,410, ES=0.23; 95% CI: 0.09~0.37), coping and self-efficacy (n=179, ES=0.68; 95% CI: 0.26~1.11), anxiety (n=1,786, ES=-0.26; 95% CI: -0.37~-0.15), depression (n=1,910, ES=-0.28; 95% CI: -0.37~-0.18), and psychological distress (n=2,242, ES=-0.31; 95% CI: -0.46~-0.17). Subgroup analysis showed that counseling was the most effective intervention for quality of life, and behavioral therapy was an effective intervention for all positive and negative outcomes. Publication bias was not detected except for psychological distress. Conclusion: Psychoeducational intervention appears to be effective in improving quality of life and coping and self-efficacy, and it is effective in reducing psychological symptoms in cancer survivors. Behavioral therapy, especially, is commonly effective in improving psychosocial outcomes. However, low-quality evidence, variability in the designs of existing studies, and publication bias suggest that additional high-quality trials should be conducted in the future.

Objective : This study was to find out whether there was a difference between parenting stress of parents with and without sensory defensiveness and level of the quality of life, to analyze the factors related with parenting stress of parents and quality of life and to develop intervention program to improve quality of life of parents that care children with problem on sensory process. Methods : The population of this study was consisted of 82 children aged from 3 to 7 years and was treated occupational therapy in clinics or welfare centers for disabled persons. Parenting stress was assessed with Parenting Stress Index and the quality of life scales used by Lee Jeong-Eun was used to assess the level of quality of life. Result : The difference between parenting stress with and without sensory defensiveness and level of quality of life was only shown in parenting stress, and the correlation between parenting stress with and without sensory defensiveness and quality of life indicated negative correlation in both sensory defensiveness and no sensory defensiveness group(r=-0.52, r=-0.65, p<0.05). This study found there was significant difference between quality of life factors affecting parenting stress of parents and parenting stress factors affecting quality of life in sensory defensiveness and no sensory defensiveness group. Conclusion : The study showed that clinicians must develop appropriative intervention program with sensory defensiveness or without sensory defensiveness for decreasing parenting stress and increasing quality of life for their parents.
