In dysphagia, food or water cannot be delivered safely through the oral cavity to the stomach; both are treated using texture-modified food and thickened fluid. Before, each country had its own diet modifications and texture measurement standards. In 2012, the International Dysphagia Diet Standardisation Initiative (IDDSI) was developed by several countries. Owing to cultural differences, it was necessary to determine whether the IDDSI could well be applied to clinicians and patients without difficulties in East Asia countries. To evaluate the IDDSI scale to find out the difficulties applying this scale in East Asia countries to educate the clinicians and patients. In May 2021, we enrolled physicians, nurses, nutritionists, and swallowing therapists involved in dysphagia treatment at a single center in Seoul. To evaluate the degree of understanding and difficulties of adapting IDDSI to clinicians in East Asia countries, we used the 17-item questionnaire with IDDSI sample foods and foods in Asian countries. In first 7 items, we compared IDDSI with the previously used scale based on the National Dysphagia Diet (NDD). In the next 10 questions, only the IDDSI levels were answered, and the absolute values of the answer-response differences were calculated. The IDDSI showed a significantly high intraclass correlation with the previously used NDD-based scale; the coefficient was higher for the nutritionists (0.988) and swallowing therapists (0.991). When evaluating whether the IDDSI could applied well in East Asia countries, the absolute values of the answer-response differences were lower than 0.5 in majority of levels, except for Level 4. Because the IDDSI framework might successfully be applied universally regardless of food culture, a worldwide standard for food rheology in dysphagia treatment might be possible.

Objective To investigate the association between sarcopenia, sarcopenic obesity (SO), metabolic syndrome (MetS), and occupational history. Methods Using data from the Korea National Health and Nutrition Examination Survey, men more than or equal to 65 years of age (n = 679) were grouped according to occupation. Results Mean skeletal muscle mass index was higher and mean body fat mass was lower in agribusiness and low-level (AL) workers than white-collar (WC), blue-collar (BC), and pink-collar (PC) workers. The risk of sarcopenia was highest in BC, followed by WC, PC, and AL. The risk of SO was higher in WC than AL and MetS was higher in WC and BC than AL. Conclusions The development of sarcopenia, SO, and MetS is related to lifetime occupation, with BC workers being most affected by sarcopenia and WC workers being most affected by SO and MetS.

Supplemental Digital Content is available in the text, Background: Previous systemic reviews have examined the efficacy of individual therapeutic agents, but which type of treatment is superior to another has not been pooled or analyzed. The objective of the current study was to compare the clinical effectiveness of epidural steroid injection (ESI) versus conservative treatment for patients with lumbosacral radicular pain. Methods: A systematic search was conducted with MEDLINE, EMBASE, and CENTRAL databases with a double-extraction technique for relevant studies published between 2000 and January 10, 2019. The randomized controlled trials which directly compared the efficacy of ESI with conservative treatment in patients with lumbosacral radicular pain were included. Outcomes included visual analog scale, numeric rating scale, Oswetry disability index, or successful events. Two reviewers extracted data and evaluated the methodological quality of papers using the Cochrane Collaboration Handbook. A meta-analysis was performed using Revman 5.2 software. The heterogeneity of the meta-analysis was also assessed. Results: Of 1071 titles initially identified, 6 randomized controlled trials (249 patients with ESI and 241 patients with conservative treatment) were identified and included in this meta-analysis. The outcome of the pooled analysis showed that ESI was beneficial for pain relief at short-term and intermediate-term follow-up when compared with conservative treatment, but this effect was not maintained at long-term follow-up. Successful event rates were significantly higher in patients who received ESI than in patients who received conservative treatment. There were no statistically significant differences in functional improvement after ESI and conservative treatment at short-term and intermediate-term follow-up. The limitations of this meta-analysis resulted from the variation in types of interventions and small sample size. Conclusions: According to the results of this meta-analysis, the use of ESI is more effective for alleviating lumbosacral radicular pain than conservative treatments in terms of short-term and intermediate-term. Patients also reported more successful outcomes after receiving ESI when compared to conservative treatment. However, this effect was not maintained at long-term follow-up. This meta-analysis will help guide clinicians in making decisions for the treatment of patients with lumbosacral radicular pain, including the use of ESI, particularly in the management of pain at short-term.

To determine the diagnostic value of voice analysis to screen for patients with high risk of clinically significant aspiration.A total of 93 patients referred for a videofluoroscopic swallowing study were included in the study. Voice analyses were performed before and after videofluoroscopic swallowing study, and five acoustic variables were measured, including average fundamental frequency, relative average perturbation, shimmer percentage, noise-to-harmonic ratio, and voice turbulence index. The patients were divided into two groups based on the results of the videofluoroscopic swallowing study: a high-risk group with patients who had the ingested materials on or below the vocal cords and a low-risk group with patients who did not have the ingested materials on or below the vocal cords. The changes of each acoustic variable before and after the videofluoroscopic swallowing study were compared between the two groups.Relative average perturbation, shimmer percentage, noise-to-harmonic ratio, and voice turbulence index were significantly increased after videofluoroscopic swallowing study in the high-risk group as compared with the low-risk group (P0.05). The change of average fundamental frequency, however, was not significantly different between the two groups (P0.05). According to the receiver operating characteristics curve, the sensitivity of these acoustic variables in detecting aspiration or penetration ranged from 68.9% to 91.1% and specificity ranged from 68.8% to 97.9%. Relative average perturbation was the most accurate variable, with a sensitivity of 91.1% and a specificity of 97.9% in predicting aspiration or penetration. The combination of relative average perturbation and noise-to-harmonic ratio increased the sensitivity to 100% but reduced the specificity to 77.1%.Voice analysis is a safe, noninvasive, and reliable screening tool for patients with dysphagia and can detect patients at high risk of clinically significant aspiration, thereby augmenting clinical bedside examination.
