Purpose
This study aimed to synthesize evidence for the association of psychological stress with Telomere Length (TL)-a potential biomarker of cellular aging. Methods: A systematic literature search was conducted to identify eligible studies in the Cochrane Library, PubMed, Embase, and CINHAL. In this review, we included all papers published since the initiative's inception and summarized results as of March 2022. Studies that investigated subjective stress using questionnaires and objective stress using biomarkers of adults (aged≥18 years) were included. Ultimately, 20 studies met our selection criteria. The risk of bias was assessed using the Newcastle-Ottawa Scale. Results: Fifteen of the twenty studies (75.0%) reported that individuals with higher psychological stress levels had shorter TL. Eleven of sixteen studies (68.8%) measuring subjective stress and five of eight studies (62.5%) measuring objective stress showed significant associations of psychological stress with TL. However, five studies reported no association between psychological stress and TL shortening. Although the heterogeneous studies limited the ability to draw clear conclusions, it is suggested that psychological stress might accelerate the erosion of telomere ends.
Conclusion
Our findings indicate that TL could be a useful emerging biomarker for measuring stress-related health outcomes in nursing. Further large-scale longitudinal studies using TL as a genetic biomarker with multidimensional stress measurements are needed to investigate the association between psychological stress and cellular senescence.

PURPOSE
This study aimed to investigate the improvement in lifestyle of patients with Colorectal Cancer (CRC) by examining their lifestyle before and after diagnosis, and to identify the factors influencing lifestyle improvement to prevent the recurrence of CRC.
METHODS
The participants were 125 patients with CRC who visited the outpatient clinic of Kyungpook National University Chilgok Hospital in Daegu from December 2017 to March 2018. Questionnaires consisted of items on CRC-related lifestyle, knowledge of lifestyle risks for CRC, beliefs of lifestyle improvement (perceived benefits and barriers), self-efficacy, and fear of cancer recurrence. Lifestyle improvement referred to the score given to the improved lifestyle through the score difference in the measure of lifestyle related to CRC before and after diagnosis. The collected data were analyzed using SPSS/WIN 21.0 program.
RESULTS
The factors influencing lifestyle improvement were gender (β=.46, p<.001), age (β=.31, p<.001), knowledge of lifestyle risks for CRC (β=.20, p=.005), perceived benefits of lifestyle improvement (β=.19, p=.008), and number of discomforts(symptoms) that impede lifestyle improvement (β=.17, p=.016). These variables explained 38% of CRC patients' lifestyle improvement.
CONCLUSION
These findings suggest that we need to find ways to provide knowledge of the lifestyle risks for CRC to patients with CRC and improve their perceptions of the benefits of lifestyle improvement to promote lifestyle improvement and help prevent the recurrence of CRC after CRC diagnosis.

PURPOSE
The purpose of this study was to identify factors associated with insomnia in college students with Irritable Bowel Syndrome (IBS).
METHODS
College students with IBS (n=259) were recruited in 4 universities in Daegu city and Ulsan city, South Korea. Participants completed questionnaires measuring the following variables: insomnia (Insomnia Severity Index [ISI]), dysfunctional beliefs and attitudes about sleep (Dysfunctional Beliefs and Attitudes about Sleep Scale-16 [DBAS-16]), pre-sleep arousal (Pre-Sleep Arousal Scale [PSAS]), gastrointestinal symptoms during sleep (Gastrointestinal Symptoms during Sleep), sleep hygiene (Sleep Hygiene Practices Scale [SHPS]), psychological distress (Brief Symptom Inventory-18 [BSI-18]), and IBS symptom severity(IBS Severity Scoring System [IBS-SSS]).
RESULTS
In our participants, 53.3%(n=138) reported having insomnia (ISI score ≥10). Compared to the non-insomnia group (n=121), the insomnia group reported significantly higher scores in DBAS-16, PSAS, gastrointestinal symptoms during sleep, IBS-SSS, SHPS, and BSI-18 (p < .001 for all). Multiple logistic regression analysis revealed that gastrointestinal symptoms during sleep (Odds Ratio [OR]=2.77, 95% Confidence Interval [CI]: 1.29~5.96), dysfunctional beliefs and attitudes about sleep (OR=1.04, 95% CI: 1.03~1.06), cognitive arousal before sleep (OR=1.10, 95% CI: 1.05~1.17), and somatization (OR=1.12, 95% CI: 1.02~1.23) were associated with insomnia in this sample.
CONCLUSION
Our findings indicate that insomnia is a serious problem for college students with IBS and that gastrointestinal symptoms during sleep and sleep related dysfunctional cognitions should be managed to improve insomnia of them.

PURPOSE
The purpose of this study was to investigate the effects of knowledge, attitude, and self-efficacy of cardiopulmonary resuscitation (CPR) and the willingness of family members to perform the CPR to their loved one with heart disease.
METHODS
226 participants whose family member is hospitalized with heart disease were recruited from two hospitals in Daegu city. Data were collected by using questionnaires which included demographic characteristics, factors including knowledge, attitude, and self-efficacy and the willingness to perform CPR.
RESULTS
Participants reported on their level of knowledge, attitude, and self-efficacy of CPR at the following levels: 9.16±2.66, 35.55±5.56, and 63.83±19.37 respectively. Only 53% of the participants reported prior CPR training, and 67.7% indicated that they would be willing to perform CPR to their family member with heart disease. Of the participants without prior CPR training, 34% reported that they did not recognize the importance of CPR training. Participants reported attitude (p=.002) and self-efficacy (p=.040) predicted willingness to perform CPR. Age (p < .001), gender (p=.004), educational level (p < .001), occupation (p < .001), prior CPR training (p < .001) were related to willingness to perform CPR.
CONCLUSION
This study findings suggest that it is necessary to develop educational programs for public to improve competent CPR performance.
