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.

Anterior cervical hyperostosis may be a cause of dysphagia. For anterior cervical hyperostosis, medical or surgical treatments can be adhibited in view of the causative mechanisms and intensities of dysphagia. We report 3 cases of cervical hyperostosis-derived progressive dysphagia that underwent operation. Radiologic diagnosis and Video Fluoroscopic Swallowing Study were performed on the three patients for evaluation. One had history of recurrent aspiration pneumonia accompanied by weight loss, another complained of dysphagia only when swallowing pills, and the third experienced recurrence symptom with reossification. All patients reported gradual improvement of dysphagia immediately after their cervical osteophytes were resected through the anterior approach. In relation to postoperative improvement, however, they expressed different degrees of satisfaction according to severity of symptoms. Surgical treatment, performed for the anterior cervical hyperostosis-derived dysphagia, can immediately relieve symptoms of difficulty in swallowing. This might especially be considered as an appropriate treatment option for severe dysphagia.

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.

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.

Purpose: Bone age (BA) is needed to assess developmental status and growth disorders. We evaluated the clinical performance of a deep-learning-based BA software to estimate the chronological age (CA) of healthy Korean children. Methods: This retrospective study included 371 healthy children (217 boys, 154 girls), aged between 4 and 17 years, who visited the Department of Pediatrics for health check-ups between January 2017 and December 2018. A total of 553 left-hand radiographs from 371 healthy Korean children were evaluated using a commercial deep-learning-based BA software (BoneAge, Vuno, Seoul, Korea). The clinical performance of the deep learning (DL) software was determined using the concordance rate and Bland-Altman analysis via comparison with the CA. Results: A 2-sample t-test (P<0.001) and Fisher exact test (P=0.011) showed a significant difference between the normal CA and the BA estimated by the DL software. There was good correlation between the 2 variables (r=0.96, P<0.001); however, the root mean square error was 15.4 months. With a 12-month cutoff, the concordance rate was 58.8%. The Bland-Altman plot showed that the DL software tended to underestimate the BA compared with the CA, especially in children under the age of 8.3 years. Conclusion The DL-based BA software showed a low concordance rate and a tendency to underestimate the BA in healthy Korean children.

Purpose: Melanoma is a potentially fatal cutaneous malignancy and regional lymph node (LN) metastases are the most important predictors of mortality. This study aimed to analyze clinical features and risk factors of complications associated with inguinal LN dissection (LND) to establish treatment protocols. Methods: This single-center retrospective study (2000 to 2018) consisted of patients who underwent inguinal area sentinel LN biopsy (SLNB) or LND due to malignant melanoma. Risk factors and outcomes were analyzed. Results: One hundred patients underwent SLNB alone (n=67; patients with negative SLNB), complete LND (CLND) after positive SLNB (n=19), or radical LND without SLNB (n=14). Five-year overall survival and disease-free survival rates among these groups were 87.3%, 57.4%, and 61.9%, and 59.0%, 22.7%, and 28.1%, respectively. The complication rate in the SLNB alone group was lower than the other groups (22.4% vs. 47.4% and 35.7%, respectively; P=0.048). Seroma was the most common complication in the SLNB alone group (15.0%); lymphedema was most common in the CLND after SLNB group (21.1%). Multivariate analysis of risk factors for postoperative complications found the hazard ratio for body mass index >28 kg/m2 was 4.376 (95% confidence interval [CI], 1.243–15.401; P=0.022). The hazard ratio for LND (including CLND after SLNB and radical LND without SLNB) was 3.263 (95% CI, 1.248–8.529; P=0.016). Conclusion Inguinal LND is a higher risk procedure compared to SLNB and other sites for postoperative complications, irrespective of meticulous surgical techniques. More studies are needed to establish treatment protocols (e.g., observation vs. CLND after a positive SLNB result) and the risks and benefits in Asian populations.
