BACKGROUND: This study quantitatively and qualitatively analyzed the characteristics and trends of papers published in the Journal of the Korean Geriatrics Society. METHODS: Original articles, case reports, review articles published from 2006 to 2013 were retrospectively examined. All of the article research topics, paper-specific corresponding author's affiliations and number of authors were investigated. Original articles were separated and grouped according to research designs. Using the Korean Citation Index, impact factor of this journal was examined and compared with four related journals. RESULTS: Of the 276 articles analyzed, 159 (57.6%) were original articles, 145 (91.2%) were analytic studies, and 36 (22.6%) were experimental studies. The proportion of original articles accounted for about 60% until 2007 but decreased to 41.0% in 2013. By clinical study topics, 37 studies (13.4%) addressed the understanding of geriatric diseases and 45 studies (16.3%) were focused on nervous system diseases. The median number of authors for the 276 studies was 6. Internal medicine accounted for the largest proportion of corresponding author's affiliation (109 studies, 39.5%) studies. Impact factor of the journal increased from 0.05 (4th position) in 2009 to 0.48 (3rd position) in 2011. CONCLUSION: Articles published in the Journal of the Korean Geriatrics Society increasingly included experimental studies based on evidence-centered medicine, with the proportion of original articles decreasing. The impact factor increased annually along with the journal ranking, compared with other journals. Journal of the Korean Geriatrics Society is judged to be qualitatively improving.

PURPOSE: The purpose of this study was to develop a multi-disciplinary self-management intervention based on empowerment theory and to evaluate the effectiveness of the intervention for older adults with chronic illness. METHODS: A randomized controlled trial design was used with 43 Korean older adults with chronic illness (Experimental group=22, Control group=21). The intervention consisted of two phases: (1) 8-week multi-disciplinary, team guided, group-based health education, exercise session, and individual empowerment counseling, (2) 16-week self-help group activities including weekly exercise and group discussion to maintain acquired self-management skills and problem-solving skills. Baseline, 8-week, and 24-week assessments measured health empowerment, exercise self-efficacy, physical activity, and physical function. RESULTS: Health empowerment, physical activity, and physical function in the experimental group increased significantly compared to the control group over time. Exercise self-efficacy significantly increased in experimental group over time but there was no significant difference between the two groups. CONCLUSION: The self-management program based on empowerment theory improved health empowerment, physical activity, and physical function in older adults. The study finding suggests that a health empowerment strategy may be an effective approach for older adults with multiple chronic illnesses in terms of achieving a sense of control over their chronic illness and actively engaging self-management.

Objective: The chest compression depth recommended in the current guidelines for average adult cardiopulmonary resuscitation is approximately 1/4-1/5 depth of the external chest anteroposterior (AP) diameter and at least 50 mm but less than 60 mm. The purpose of this study was to determine the proper compression depth in patients with amyotrophic lateral sclerosis (ALS). Methods: A retrospective analysis of the chest computed tomography scans obtained between January 2014 and December 2018 was performed, and the chest anatomical parameters, such as external, internal chest, and heart AP diameters, were measured. The primary outcomes were a 1/4 and 1/5 depth of an external chest AP diameter. Based on the values of these parameters, the heart compression fractures (HCF) and over compression depth (OCD) from 40 to 60 mm depths with every 5 mm interval were calculated. All outcomes in the two groups were compared. Results: Ninety three of 108 ALS and 93 of 17,150 healthy individuals were selected randomly from a database and analyzed. The mean±standard deviations of 1/4 and 1/5 depth of the external chest AP diameter in ALS were significantly lower than in healthy individuals (48.57±4.60 mm vs. 53.43±4.93 mm, 38.86±3.68 mm vs. 42.75±3.94 mm, respectively, all P<0.001). The HCF values were similar in the two groups. The number of OCD with 55 and 60 mm in the ALS group were increased (all P<0.05, univariate analysis) Conclusion An approximately 50 mm depth of chest compression could be appropriate, but an excessive depth greater than 55 mm is more likely to cause complications for ALS patients.

BACKGROUND: Osteoporosis and osteopenia are characterized by reduced bone mineral density (BMD) and increased fracture risk. Although the risk of fractures is higher in underweight people than in overweight people, the accumulation of body fat (especially abdominal fat) can increase the risk of bone loss. This study aimed to evaluate the association between body fat percentage and BMD in normal-weight middle-aged Koreans. METHODS: This study included 1,992 adults (mean age, 48.7 years; 52.9% women). BMD and body fat were measured using dual-energy X-ray absorptiometry. Multiple linear regression analyses and analysis of covariance were used to assess the association between BMD and body fat. Body fat percentage was grouped by cut-off values. The cut-off values were 20.6% and 25.7% for men with a body mass index of 18.5–22.9 kg/m2, while the cut-off values were 33.4% and 36% for women. RESULTS: Body fat percentage tended to be negatively associated with BMD. Increased body fat percentage was associated with reduced BMD in normal-weight middle-aged adults. The effects of body fat percentage on BMD in normal-weight individuals were more pronounced in men than in women. CONCLUSION: There was a negative correlation between BMD and body fat percentage in middle-aged Korean men and women with normal body weight. This association was stronger in men than in women.

A low-dose chest CT is performed for early detection of lung cancer, but the CT scan frequently shows several incidental abnormalities. Identification of the incidental findings may enable early detection of diseases other than lung cancer, thereby improving the survival of the individual undergoing screening. However, insignificant incidental abnormalities may cause unnecessary additional examination and costs. It is crucial for radiologists to appropriately comprehend and report significant incidental abnormalities other than lung cancer for successful implementation of the national lung cancer screening program in Korea.
