The aim of this study is to determine whether levels of circulating free DNA (cfDNA) increase according to cancer progression, whether they are restored after surgical resection, and to evaluate cfDNA in gastric cancer patients as a useful biomarker. A case-control study design was used. Thirty gastric cancer patients and 34 healthy subjects were enrolled from two hospitals in South Korea. The plasma cfDNA of patients with gastric cancer were obtained before surgery and 24 hours after surgery, and then analyzed by a quantitative, real-time polymerase chain reaction. Plasma samples were also obtained from the control group. The mean levels of cfDNA in the healthy control group, patients with early gastric cancer, and with advanced gastric cancer were 79.78 ± 8.12 ng/mL, 106.88 ± 12.40 ng/mL, and 120.23 ± 10.08 ng/mL, respectively (P < 0.01). Sensitivity was 96.67% and specificity was 94.11% when the cutoff value was 90 ng/mL. Variables representing the tumor burden such as tumor size, T stage, TNM stage, and curative resection are also associated with the levels of cfDNA. The levels of cfDNA in the 24-hour-after-surgery group decreased significantly (112.17 ± 13.42 ng/mL vs. 77.93 ± 5.94 ng/mL, P < 0.001) compared to the levels of cfDNA in the preoperation group. The changes in the levels of cfDNA can act as reliable biomarkers to detect cancer early, to predict tumor burden, estimate curative resection and even prognosis.

Background: Palliative care is a patient-centred, integrated approach for improving quality of life for both patients facing life-threatening illnesses and for their families. Although there has been increased interest in palliative care for non-cancer patients, the palliative care competency of nurses who care for non-cancer patients has rarely been investigated. This study described the palliative care knowledge, attitude, confidence, and educational needs in nurses who care for patients with congestive heart failure, stroke, end-stage renal disease, and end-stage liver disease; explored the relationships between those variables; and identified factors affecting nurses’ palliative care confidence. Methods: A cross-sectional, descriptive, correlational design was employed; data collection was conducted at a tertiary hospital in Seoul, Korea. Nurses who were working in general wards and intensive care units (N = 102) completed valid and reliable self-administered questionnaires. Descriptive statistics, frequencies, independent t-tests, one-way ANOVA, Pearson’s correlations, and multiple regression were conducted to analyse the data. Results: Nurses’ palliative care knowledge level was low (9.73 ± 2.10; range = 0–20) and their attitude toward palliative care was moderate (87.97 ± 6.93, range: 30–120). Knowledge was significantly correlated with attitude (r = .29, p = .003). Nurses were highly confident in pain and symptom management but demonstrated high educational needs for managing human and material resources to provide palliative care. Previous training in hospice, palliative, and EOL care was a significant and modifiable factor that affected nurses’ confidence (std. β = 0.25, p = .010). Conclusions: To facilitate high-quality palliative care for non-cancer patients and families, nursing education programs should be developed to address nurses’ knowledge level, confidence level, and educational needs. This study provides relevant information that can be utilised to develop palliative care educational programs for nurses who care for non-cancer patients.

Background: Digital care has become an essential component of health care. Interventions for patients with cancer need to be effective and safe, and digital health interventions must adhere to the same requirements. Objective: The purpose of this study was to identify currently available digital health interventions developed and evaluated in randomized controlled trials (RCTs) targeting adult patients with cancer. Methods: A scoping review using the JBI methodology was conducted. The participants were adult patients with cancer, and the concept was digital health interventions. The context was open, and sources were limited to RCT effectiveness studies. The PubMed, CINAHL, Embase, Cochrane Library, Research Information Sharing Service, and KoreaMed databases were searched. Data were extracted and analyzed to achieve summarized results about the participants, types, functions, and outcomes of digital health interventions. Results: A total of 231 studies were reviewed. Digital health interventions were used mostly at home (187/231, 81%), and the web-based intervention was the most frequently used intervention modality (116/231, 50.2%). Interventions consisting of multiple functional components were most frequently identified (69/231, 29.9%), followed by those with the self-manage function (67/231, 29%). Web-based interventions targeting symptoms with the self-manage and multiple functions and web-based interventions to treat cognitive function and fear of cancer recurrence consistently achieved positive outcomes. More studies supported the positive effects of web-based interventions to inform decision-making and knowledge. The effectiveness of digital health interventions targeting anxiety, depression, distress, fatigue, health-related quality of life or quality of life, pain, physical activity, and sleep was subject to their type and function. A relatively small number of digital health interventions specifically targeted older adults (6/231, 2.6%) or patients with advanced or metastatic cancer (22/231, 9.5%). Conclusions: This scoping review summarized digital health interventions developed and evaluated in RCTs involving adult patients with cancer. Systematic reviews of the identified digital interventions are strongly recommended to integrate digital health interventions into clinical practice. The identified gaps in digital health interventions for cancer care need to be reflected in future digital health research.

The purpose of this study was to describe Korean nurses' knowledge of hospice and palliative care and to identify the effect of an End-of-Life Nursing Education Consortium course on Korean nurses' palliative care knowledge. The study used a pretest and posttest design. A Korean version of the Palliative Care Quiz for Nursing was administered to 111 Korean nurses who had attended the course. To analyze the data, paired t tests and repeated-measures analysis of variance were conducted. The average level of Korean nurses' knowledge of hospice and palliative care was 12.5/20 points at the beginning of the course. Nurses with hospice certification scored higher than those who were not certified. Nurses with associate degrees scored significantly lower than those with master's and doctoral degrees. After attending the course, the knowledge of hospice and palliative care increased among all groups, especially significantly higher for the group of nurses never certified in hospice and palliative nursing. Overall, the End-of-Life Nursing Education Consortium course was effective for Korean nurses in increasing the knowledge on hospice and palliative care. Recommendations include continuous evaluation of the course with an instrument sensitive to Korean culture.

Palliative care is an important element of holistic care but has received little attention in cardiac disease patients. The purpose of the paper is (a) to investigate nurses’ knowledge of palliative care, attitudes toward care of the dying, coping with death, and preparedness to practice palliative care for those with heart failure, and (b) to evaluate influencing factors on preparedness to practice on palliative care. A cross-sectional descriptive design employed a structured questionnaire that tested nurses’ knowledge, attitude, coping, and preparedness to practice on palliative care for patients with heart failure. Ninety nurses in two tertiary university hospitals in South Korea participated in the survey. Data were analyzed with descriptive statistics, correlation, and multiple regression. Results showed low levels of knowledge reported (an average of 48.3% correct answers), attitude (134.8±110.1), coping (117.2±24.3), and preparedness to practice (17.3±4.7) relating to palliative care. The extent of knowledge was related to both attitudes and coping. These attitudes and coping skills were related to preparedness to practice. The multiple regression analysis showed that preparedness to practice was explained by coping and attitude (R² =0.46, F=6.1, p<0.001). Palliative care training is urgently needed to improve knowledge, attitude, coping, and preparedness to practice. Guidance to assist healthcare professionals involved in palliative care for those with cardiac disease needs to be developed and provided.

Background: Non-cancer patients experience the chronic process of disease that increases the patients’ suffering as well as families’ care burden. Although two-thirds of deaths are caused by non-cancer diseases, there is a lack of studies on palliative care for non-cancer patients. This study identified the palliative care needs and satisfaction, anxiety and depression, and health-related quality of life (HRQOL) of non-cancer patients and identified the factors influencing their HRQOL. Methods: A cross-sectional survey design was employed. Participants were 114 non-cancer patients with chronic heart failure, stroke, end-stage renal disease, or end-stage liver disease who were admitted to the general ward of a tertiary hospital in South Korea. Measures included the Palliative Care Needs and Satisfaction Scale, the Hospital Anxiety and Depression Scale, and the Medical Outcome Study 36-items Short Form Health Survey version 2. Data were analysed with descriptive statistics, independent t-tests, analyses of variance, Pearson’s correlations, and multiple linear regression analyses. Results: The average score of palliative care needs was 3.66 ± 0.62, which falls between ‘moderate’ and ‘necessary’. Among the four domains, the average score of palliative care needs in the psychosocial domain was the highest: 3.83 ± 0.67. Anxiety was nearly in the normal range (7.48 ± 3.60; normal range = 0–7) but depression was higher than normal (9.17 ± 3.71; normal range = 0–7). Similar to patients with cancer, physical HRQOL (38.89 ± 8.69) and mental HRQOL (40.43 ± 11.19) were about 80% of the general population’s score (50 points). Duration of disease and physical performance were significant factors associated with physical HRQOL, whereas physical performance, anxiety, and depression were significant factors associated with mental HRQOL. Conclusion: It is necessary to maintain non-cancer patients’ physical performance and assess and manage their mental health in advance for effective palliative care. This study provides relevant information that can be used to develop a tailored palliative care model for non-cancer patients.
