ABSTRACT
Purpose@#Despite the high prevalence of visual impairment caused by diabetic retinopathy and nutritional problems among older adults with diabetes, evidence regarding factors related to nutritional risk in this population is limited. Therefore, this study aimed to identify the correlates of nutritional risk among older adults with diabetes, focusing on visual impairment. @*Methods@#This study was a secondary data analysis of the 2020 National Survey of Older Koreans aged 65 years and above. The sample comprised 2,376 older adults with diabetes, and complex sample ANOVA and Rao–Scott chi-square tests were used to compare the groups according to visual impairment. Complex-sample logistic regression analyses were conducted to verify the association between visual impairment and nutritional risk. @*Results@#Older adults with diabetes, who also have severe visual impairment, are more likely to have nutritional risk status than those without impairment after controlling for covariates (odds ratio [OR] = 2.44, 95% confidence interval [CI] 1.16~5.13). Among the covariates, depression (OR = 3.58, 95% CI 2.60~4.94), dependent activities of daily living status (OR = 2.79, 95% CI 1.60~4.86), and experience of hospitalization during the past year (OR = 2.51, 95% CI 1.57~4.03) were strongly associated with nutritional risk. @*Conclusion@#Severe visual impairment increases the nutritional risk among older adults with diabetes. Therefore, it is essential to prevent visual impairment due to exacerbation of diabetes through appropriate management. Additionally, tailored nutritional interventions for visually impaired older adults with diabetes that consider visual characteristics are required.
ABSTRACT
Purpose@#: The aim of this study was to propose appropriate nurse staffing of adult intensive care units considering patients’ nursing care needs according to the Workload Management System for Critical Care Nurses (WMSCN). @*Methods@#: In a cross-sectional survey conducted in September 2017, 1,786 patients’ WMSCN scores, surveys from 2,145 nurses, and administrative data from 118 units in 41 hospitals were analyzed. The means (standard deviations) of the aforementioned scores and nursing hours per patient day were presented. Nurse-to-patient ratios and nurse-to bed ratios for staffing to meet patients’ nursing care needs were calculated. @*Results@#: The mean WMSCN scores were 109.50±17.17 in tertiary hospitals and 96.38±19.26 in general hospitals. Nursing hours per patient day were 12.47±2.80 in tertiary hospitals and 11.01±2.45 in general hospitals. Nursing hours per patient day correlated with WMSCN scores. Nurse-to-bed ratios required for the provision of ICU nursing care ranged from 1: 0.36 to 1: 0.48. @*Conclusion@#: Our findings provide evidence that current ICU nurse staffing is insufficient for meeting patients’ nursing care needs. We suggest adjusting the legal standards for adequate nurse staffing considering these needs.

ABSTRACT
Purpose@#This study aimed to understand and describe the diabetes self-management experience of visually impaired people with diabetes. @*Methods@#Ten participants were recruited through a website used by the visually impaired from February to March 2020. Data were collected through two focus group interviews conducted in June 2020; each group consisted of five participants. All interviews were recorded with the consent of the participants and transcribed verbatim. The transcribed data were analyzed using qualitative content analysis. @*Results@#Seven categories were as follows; a two-faced, lifelong companion, an unprepared encounter, struggle to live, love-hate relationship with family, strategies to adapt, lessening attention to self-management, the desire to learn properly. @*Conclusion@#It can be concluded that the visually impaired have fewer opportunities for receiving diabetes self-management education than general diabetic patients. Consequently, plans to improve the education available to such patients are required. Additionally, psychological counseling and diabetes education for patients’ families are necessary, and improving the perception of medical workers regarding the visually impaired will be prove useful.
ABSTRACT
Objective: To investigate the anti-inflammatory effects of Jeju seaweeds on macrophage RAW 264.7 cells under lipopolysaccharide (LPS) stimulation.Methods:Ethyl acetate fractions were prepared from five different types of Jeju seaweeds, Dictyopteris divaricata (D. divaricata), Dictyopteris prolifera (D. prolifera), Prionitis cornea (P. cornea), Grateloupia lanceolata (G. lanceolata), and Grateloupia filicina (G. filicina). They were screened for inhibitory effects on proinflammatory mediators and cytokines such as nitric oxide (NO), prostaglandin E2, tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6).Results:Our results revealed that D. divaricata, D. prolifera, P. cornea, G. lanceolata, and G. filicina potently inhibited LPS-stimulated NO production (IC50 values were 18.0, 38.36, 38.43, 32.81 and 37.14 μg/mL, respectively). Consistent with these findings, D. divaricata, D. prolifera, P. cornea, and G. filicina also reduced the LPS-induced and prostaglandin E2 production in a concentration-dependent manner. Expectedly, they suppressed the expression of inducible NO synthase and cyclooxygenase-2 at the protein level in a dose-dependent manner in the RAW 264.7 cells, as determined by western blotting. In addition, the levels of TNF-α and IL-6, released into the medium, were also reduced by D. divaricata, D. prolifera, P. cornea, G. lanceolata, andG. filicina in a dose-dependent manner (IC 50 values for TNF-α were 16.11, 28.21, 84.27, 45.52 and 74.75 μg/mL, respectively; IC50 values for IL-6 were 37.35, 80.08, 103.28, 62.53 and 84.28 μg/mL, respectively). The total phlorotannin content was measured by the Folin-Ciocalteu method and expressed as phloroglucinol equivalents. The content was 92.0 μg/mg for D. divaricata, 151.8 μg/mg for D. prolifera, 57.2 μg/mg for P. cornea, 53.0 μg/mg for G. lanceolata, and 40.2 μg/mg for G.filicina. Conclusions: Thus, these findings suggest that Jeju seaweed extracts have potential therapeutic applications for inflammatory responses.
