PURPOSE: Although the prevalence rate of chronic diseases is rapidly increasing due to an unhealthy diet in Korea, nurses may not have enough nutritional knowledge to educate their patients. This study investigated the level of nurses' nutritional knowledge for chronic diseases as well as for strokes, and the needs for nurses' nutritional education. METHODS: This research is a descriptive research conducted from April to August of 2014, on 242 nurses who work with stroke patients, in two tertiary general hospitals in the city of Seoul, South Korea. RESULTS: The average nutritional knowledge score of our subjects was 19.9+/-2.51 (range 12-24). The correct response rate was 83% which was higher than expected. However, many nurses (31-66%) answered incorrectly on items such as 'Drinking low-fat milk is better than whole milk', and 'Seasoning with a large amount of soy sauce instead of salt can reduce sodium consumption'. We also found that nurses who received continuing education regarding nutrition scored higher than those who did not (p=.020). There was no correlation between nutritional knowledge and the need for nutritional education (r=.034, p=.601). CONCLUSION: The level of nutritional knowledge of the nurses was relatively low and irrelevant to the completion of nutrition courses during university or duration of experience. Rather, the relevance was higher when the nurse received nutrition-related training after graduating from university. Our results imply that continuous nutritional education is necessary for hospital nurses.

The present study is the first one to investigate the impacts of depression and somatization on the disease severity and quality of life (QoL) in patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). The Korean version of National Institutes of Health (NIH)- Chronic Prostatitis Symptom Index (CPSI) for severity of CP/CPPS. Korean version of Patient Health Questionnaire-9 (PHQ-9) for depression, Korean version of Patient Health Questionnaire-15 (PHQ-15) for somatization, and Korean version of EuroQol Questionnaire-5 Dimensions (EQ-5D)- [(EQ-5D utility index and visual analog scale (EQ-5D VAS)] for QoL, were administered. Eighty patients were enrolled. The NIH-CPSI total scores were significantly higher in those with depression (25.3%, p=0.01) or somatization (23.2%, p=0.03) than in those without. These trends toward significantly negative influence of depression and somatic symptoms on QoL were also observed. Our preliminary results indicate that depression and somatization may have negative influence on the symptom severity and QoL in patients with CP/CPPS. However, adequately-powered and more well-designed studies are mandatory to prove our results.

This is the first study to investigate the influence of depression, anxiety and somatization on the treatment response for lower urinary tract symptoms/benign prostatic hyperplasia (LUTS/BPH). The LUTS/BPH patients were evaluated with the Korean versions of the International Prostate Symptom Score (IPSS), the Patient Health Questionnaire-9 (PHQ-9), the 7-item Generalized Anxiety Disorder Scale (GAD-7) and the PHQ-15. The primary endpoint was a responder rate defined by the total score of IPSS (< or = 7) at the end of treatment. The LUTS/BPH severity was significantly higher in patients with depression (whole symptoms P = 0.024; storage sub-symptom P = 0.021) or somatization (P = 0.024) than in those without, while the quality of life (QOL) was significantly higher in patients with anxiety (P = 0.038) than in those without. Anxious patients showed significantly higher proportion of non-response (odds ratio [OR], 3.294, P = 0.022) than those without, while somatic patients had a trend toward having more non-responders (OR, 2.552, P = 0.067). Our exploratory results suggest that depression, anxiety and somatization may have some influences on the clinical manifestation of LUTS/BPH. Further, anxious patients had a lower response to treatment in patients with LUTS/BPH. Despite of limitations, the present study demonstrates that clinicians may need careful evaluation of psychiatric symptoms for proper management of patients with LUTS/BPH.

This study investigated the relationship of personality, depression, somatization, anxiety with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH). The LUTS/BPH patients were evaluated with the International Prostate Symptom Score (IPSS), 44-item Big Five Inventory (BFI), the Patient Health Questionnaire-9 (PHQ-9), the PHQ-15, and 7-item Generalized Anxiety Disorder Scale (GAD-7). The LUTS/BPH symptoms were more severe in patients with depression (p=0.046) and somatization (p=0.024), respectively. Neurotic patients were associated with greater levels of depression, anxiety and somatisation (p=0.0059, p=0.004 and p=0.0095, respectively). Patients with high extraversion showed significantly low depression (p=0.00481) and anxiety (p=0.035) than those with low extraversion. Our exploratory results suggest patients with LUTS/BPH may need careful evaluation of psychiatric problem including depression, anxiety and somatization. Additional studies with adequate power and improved designs are necessary to support the present exploratory findings.

Background: and Purpose: Growing evidence has shown that cognitive interventions can mitigate cognitive decline in patients with mild cognitive impairment (MCI). However, most previous cognitive interventions have been group-based programs. Due to their intrinsic limitations, group-based programs are not widely used in clinical practice. Therefore, we have developed a tablet-based cognitive intervention program. This preliminary study investigated the feasibility and effects of a 12-week structured tablet-based program on cognitive function in patients with MCI. Methods: We performed a single-arm study on 24 patients with MCI. The participants underwent a tablet-based cognitive intervention program 5 times a week over a 12-week period. The primary outcome was changes in cognitive function, measured using the Korean version of the Consortium to Establish a Registry for Alzheimer’s Disease Assessment Packet (CERAD-K). Outcomes were evaluated at baseline, within two weeks of the last program (post-intervention), and at the six-month follow-up session. Results: The completion rate of the tablet-based program was 83.3% in patients with MCI.The program improved cognitive function based on the CERAD-K total score (p=0.026), which was maintained for at least three months (p=0.004). There was also an improvement in the depression scale score (p=0.002), which persisted for three months (p=0.027). Conclusions Our 12-week structured tablet-based program is feasible for patients with MCI.Furthermore, although further studies with a double-arm design are required, the program appears to be an effective strategy to prevent cognitive decline in patients with MCI.

BACKGROUND: Stem cell-based transplantation therapy holds promise for peripheral nerve injury treatment, but adult availability is limited. A cell culture protocol utilizing a small-molecule cocktail effectively reprogrammed stem cells from apical papilla (SCAPs) into neural progenitor cells, subsequently differentiating into neuron-like cells. This study aims to evaluate neural-induced SCAPs, with and without small-molecule cocktail, for sciatic nerve repair potential. METHODS: A scaffold-free cell sheet technique was used to construct a three-dimensional cell sheet. Subsequently, this cell sheet was carefully rolled into a tube and seamlessly inserted into a collagen conduit, which was then transplanted into a 5 mm sciatic nerve injury rat model. Functional sciatic nerve regeneration was evaluated via toe spread test, walking track analysis and gastrocnemius muscle weight. Additionally, degree of sciatic nerve regeneration was determined based on total amount of myelinated fibers. RESULTS: Small-molecule cocktail induced SCAPs enhanced motor function recovery, evident in improved sciatic function index and gastrocnemius muscle retention. We also observed better host myelinated fiber retention than undifferentiated SCAPs or neural-induced SCAPs without small-molecule cocktail. However, clusters of neuron-like cell bodies (surrounded by sparse myelinated fibers) were found in all cell sheet-implanted groups in the implantation region. This suggests that while the implanted cells likely survived transplantation, integration was poor and would likely hinder longterm recovery by occupying the space needed for host nerve fibers to project through. CONCLUSION Neural-induced SCAPs with small-molecule cocktail demonstrated promising benefits for nerve repair; further research is needed to improve its integration and optimize its potential for long-term recovery.
