Purpose: : This study aimed to investigate the effects of oropharyngeal sensory stimulation using low-temperature capsaicin on dysphagia, dietary level, aspiration pneumonia, and nutritional status in acute stroke patients with dysphagia admitted to a stroke intensive care unit. Methods: : This study used a randomized controlled trial design and 43 participants were randomly assigned to the experimental group (n=21) or control group (n=22). An oropharyngeal sensory stimulation intervention program was constructed based on previous studies. The intervention was provided before meals twice a day for seven days and started with the first meal after hospitalization. In the control group, a solution was made using only bottled water without adding capsaicin solution, and the intervention was provided at the same time, method, and number of times as the experimental group. Results: : As a result of the study, dysphagia and dietary level improved in the experimental group that received oropharyngeal sensory stimulation using capsaicin. There were no effects on the nutritional status or aspiration pneumonia. Conclusion : This study provides basic data for the development of an intervention program for patients with dysphagia by presenting a theoretical basis that oropharyngeal sensory stimulation intervention using capsaicin improves dysphagia and dietary levels.

Purpose: This study was conducted to establish whether an ethanol extract of Lycium barbarum leaves (LLE) and an ethanol extract of Lycium barbarum leaves from which chlorophyll has been removed, denoted as LLE(Ch−), have a protective effect against hepatic fat accumulation. Methods: The inhibitory effects of LLE and LLE(Ch−) on liver fat accumulation were examined in C57BL/6 mice with non-alcoholic fatty liver disease (NAFLD) induced by an methionine and choline deficient diet and in HepG2 cells with palmitic acid-induced fat accumulation. Results: The plasma triglyceride, aspartate aminotransferase, and alanine aminotransferase levels were lower in the LLE(Ch−) group, whereas the plasma ALT activity decreased significantly in the LLE group. In both the LLE and the LLE(Ch−) groups, the triglyceride and cholesterol contents in the hepatic tissue were significantly reduced. A greater inhibitory effect on tissue fat accumulation was observed in the LLE(Ch−) group than in the LLE group. In HepG2 cells, LLE and LLE(Ch−) were non-toxic up to a concentration of 1,000 µg/mL. Compared to the control group, intracellular fat accumulation in the LLE and LLE(Ch−) groups were significantly reduced at concentrations of 200 µg/mL and 500 µg/mL, respectively. The expression of phosphorylated adenosine monophosphate-activated protein kinase and phosphorylated acetyl-CoA carboxylase in both LLE groups increased at the concentrations of 100 μg/mL and 500 μg/mL. The fatty acid synthase expression was suppressed in a concentration-dependent manner at 10 μg/mL. Conclusion The examined two ethanol extracts of LLE inhibit hepatic fat accumulation in NAFLD. This effect was more pronounced in the LLE(Ch−) group. Therefore, these 2 extracts have an anti-steatosis effect and can be used for NAFLD treatment.

Purpose: Natural medicinal plant extracts have recently attracted attention as health beneficial foods and potential therapeutic agents for prevention of various diseases. This study was undertaken to measure the anti-inflammatory effect of the ethanol-water fraction obtained from the above-ground portion of Spiraea prunifolia var. simpliciflora, a wild-growing plant in Korea. The final fraction used in this study was the H 2 O-EtOH (40:60) fraction (SP60), which had the highest antioxidant activity, as determined in previous studies. Methods: The amounts of nitric oxide (NO), tumor necrosis factor (TNF)-α, interleukin (IL)-6 and IL-1β production were measured in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells exposed to SP60. Western blot was performed to measure the expressions of inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2, and the activation of nuclear factor (NF)-κB. Results: SP60 exerted no cytotoxicity up to concentrations of 125 μg/mL. The levels of inflammatory cytokines, such as NO, TNF-α, IL-6, and IL-1β, were significantly decreased in LPS-stimulated RAW264.7 cells exposed to SP60. In addition, the expression levels of iNOS, COX-2, and phosphorylated p65 showed a concentration-dependent decrease subsequent to SP60 treatment. These results indicate that SP60 inhibits the LPS-induced production of inflammatory cytokines, iNOS, and COX-2, by inhibiting the activation of NF-κB, which is responsible for the expression of inflammatory mediators. Conclusion The results presented in this study indicate that the H 2 O-EtOH (40:60) fraction (SP60) extracted from the above-ground portion of Spiraea prunifolia var. simpliciflora has

Purpose: As introduced, multimodal pain management bundle for ileostomy reversal may be considered to reduce postoperative pain and hospital stay. The aim of this study was to evaluate clinical efficacy of perioperative multimodal pain bundle for ileostomy. Methods: Medical records of patients who underwent ileostomy reversal after rectal cancer surgery from April 2017 to March 2020 were analyzed. Sixty-seven patients received multimodal pain bundle protocol with ileostomy reversal (group A) and 41 patients underwent closure of ileostomy with conventional pain management (group B). Results: Baseline characteristics, including age, sex, body mass index, American Society of Anesthesiologists classification, diabetes mellitus, and smoking history, were not significantly different between the groups. The pain score on postoperative day 1 was significant lower in group A (visual analog scale, 2.6 ± 1.3 vs. 3.2 ± 1.2; P = 0.013). Overall consumption of opioid in group A was significant less than group B (9.7 ± 9.5 vs. 21.2 ± 8.8, P < 0.001). Hospital stay was significantly shorter in group A (2.3 ± 1.5 days vs. 4.1 ± 1.5 days, P < 0.001). There were no significant differences between the groups in postoperative complication rate. Conclusion Multimodal pain protocol for ileostomy reversal could reduce postoperative pain, usage of opioid and hospital stay compared to conventional pain management.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is the fifth leading cause of death worldwide. The awareness and treatment rate of the disease are low despite its relatively high prevalence. With the added data, this study aimed to identify changes in prevalence and risk factors of COPD using the data from the 5th KNHNES. METHODS: The subjects of this study were 8,969 individuals aged 40 and older who satisfied suitability and reproducibility for pulmonary function tests. The prevalence, awareness and risk factors of COPD were predicted based on the questionnaires on gender, age, educational level, income level, smoking history, body mass index (BMI) and other COPD related questions. RESULTS: Diagnosis of COPD was based on the airflow limitation (forced expiratory volume in one second/forced vital capacity <0.7) of the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria. The prevalence of COPD from 2010 to 2012 was 13.7%, of which 23.3% was men and 6.5% women. The prevalence was on the rise, with 12.2% in 2010, 13.2% in 2011, and 15.5% in 2012. In GOLD stage 1, the percentages of those who had cough or sputum and smoking history were 12.1% and 75.5%, respectively, but only 0.1% was diagnosed with COPD. Even after adjusting for asthma and tuberculosis, men, old age, larger amount of smoking were linked with a higher prevalence of COPD, and obese and higher educational level were associated with a lower prevalence of COPD. CONCLUSION: The prevalence of COPD in Korea has been increasing every year, and a higher prevalence was associated with male, older age, more amount of smoking, lower educational level and lower BMI.
