Aim: The Geriatric Nutritional Risk Index (GNRI) can predict nutritional risk. However, just a few studies have validated the optimal cut‐off value of GNRI for nutrition screening in older patients. Hence, this study aimed to determine the optimal value of GNRI to screen the risk of malnutrition among older patients. Methods: This retrospective cross‐sectional study was carried out with 5867 consecutive older adult patients who were admitted to an academic hospital in Japan. Receiver operating characteristic curve analyses were carried out to obtain the optimal cut‐off value of GNRI, and the results were compared against the Mini Nutritional Assessment – Short Form and Malnutrition Universal Screening Tool. The validation of the obtained cut‐off value was examined on the concordance rate of malnutrition diagnosis based on the European Society of Clinical Nutrition and Metabolism criteria. Results: The mean age of the patients was 76.0 ± 7.0 years. The optimal cut‐off value of GNRI for Mini Nutritional Assessment – Short Form ≤11 points was 95.92 (area under the curve 0.827 [0.817–0.838], P < 0.001), and that for Malnutrition Universal Screening Tool ≥1 point was 95.95 (area under the curve 0.788 [0.776–0.799], P < 0.001). By adapting GNRI <96 points as an initial screening cut‐off in the European Society of Clinical Nutrition and Metabolism‐defined malnutrition process, the concordance rates of comparisons were 98.5% and 98.5% for Mini Nutritional Assessment – Short Form‐based and MUST‐based diagnosis, respectively. Conclusions: The study showed GNRI <96 points as the optimal cut‐off value for nutritional screening. GNRI might be one of the easy‐to‐use tools for nutritional screening and for diagnosing malnutrition in older adults. Geriatr Gerontol Int 2020; 20: 811–816. [ABSTRACT FROM AUTHOR]

Background/Aims: The ability to readily diagnose sarcopenia and malnutrition in a clinical setting is essential. This study is aimed at clarifying the calf circumference (CC) cut-off values for decreased skeletal muscle mass (SMM), according to the Asian Work Group for Sarcopenia's criteria definition of sarcopenia, and those for European Society for Clinical Nutrition and Metabolism-defined malnutrition, in hospitalized Japanese patients. Methods: The study involved 1,164 patients aged ≥ 65 years. Predictive CC cut-off values were determined using receiver operating curve (ROC) analyses. The predictive validity of the cut-off values was confirmed against in-hospital mortality. Results: There were 654 females and 510 males (mean age, 83.5 ± 8.2 years). Decreased SMM and malnutrition were observed in 80.4 and 32.8% of all patients, respectively. ROC analyses identified CCs of ≤ 29 cm (female, area under the curve [AUC] 0.791) and ≤ 30 cm (male, AUC 0.832) as cut-off values for decreased SMM, and CCs of ≤ 26 cm (female, AUC 0.798) and ≤ 28 cm (male, AUC 0.837) for malnutrition. CC cut-off values for SMM and malnutrition were independently correlated with inhospital mortality. Conclusions: The study determined appropriate cut-off values for CC to identify decreased SMM and malnutrition according to the relevant guidelines. [ABSTRACT FROM AUTHOR]

Aim Sarcopenia can cause varying physical function disorders, including dysphagia. Malnutrition, a potential result of dysphagia, can also cause sarcopenia. However, the association between sarcopenia and dysphagia is not fully understood, despite evidence suggesting correlations between deglutition disorders and degenerative loss of muscle mass. The present study investigated the prevalence of dysphagia among patients with sarcopenia, and the association between the two conditions. Methods We included 224 older adults (mean age 82.5 ± 8.4 years; 37.9% men). Individuals who had a stroke or other diseases that could directly cause dysphagia were excluded. Logistic regression analyses were carried out after adjusting for potential causes of sarcopenia, including malnutrition, a low activity of daily living levels and aging, to investigate the relationship between the skeletal muscle index ( SMI), prevalence of sarcopenia diagnosed based on a low SMI and grip strength, and swallowing functions. The Mini-Nutritional Assessment short form was used to assess their nutritional status, and the Barthel Index was used to evaluate their activities of daily living. Results The prevalences of sarcopenia and dysphagia were 76.8% and 30.0%, respectively. Multivariate analysis showed that Barthel Index, SMI and presence of sarcopenia were significant independent factors for the prevalence of dysphagia, after adjusting for sex, age and nutritional status. Furthermore, subgroup analysis showed that SMI in males, and both hand-grip strength and SMI in females were lower in dysphagic subjects than in non-dysphagic subjects ( P ≤ 0.01). Conclusion Sarcopenia was an independent risk factor for dysphagia among older individuals. However, further studies are required to define causality. Geriatr Gerontol Int 2016; 16: 515-521.

This study aimed to clarify the association between texture-modified diets and poor appetite in older adults, as it is not fully understood. Cross-sectional study. We included 208 inpatients who were aged ≥65 years (mean age 78.9 ± 7.6 years, 57.7% female) and admitted to a rehabilitation unit with stroke, musculoskeletal disease, or hospital-associated deconditioning covered by the Japanese insurance system, between January 2019 and January 2020. Participants were divided into 2 groups according to their food texture level: International Dysphagia Diet Standardization Initiative (IDDSI) levels 3 to 5 for the texture-modified diet group and levels 6 and 7 for the normal diet group. Appetite was assessed using the Simplified Nutritional Appetite Questionnaire for the Japanese elderly, and a score ≤14 was defined as poor appetite. The relationship between IDDSI levels and poor appetite was analyzed using the Cochrane-Armitage trend test. Logistic regression analysis was used to investigate the relationship between the consumption of texture-modified diets and poor appetite. Statistical significance was set at P <.05. The numbers of participants on modified diets according to the IDDSI framework were as follows: 4, 11, 41, 76, and 76 in levels 3, 4, 5, 6, and 7, respectively. In total, 152 and 56 patients were classified into the regular diet group and texture-modified diet group, respectively. A significantly higher prevalence of poor appetite was observed with the consumption of texture-modified diets (P <.001 for trend). Logistic regression analysis showed that poor appetite was independently associated with the consumption of texture-modified diets (odds ratio 3.443, P =.011). These findings indicate that the consumption of texture-modified diets is associated with poor appetite. Further studies are required to verify whether a multimodal approach involving improvement in the appearance, taste, flavor, and nutrients of the food can improve poor appetite.

• We investigated the prevalence of postoperative dysphagia in older orthopedic patients. • The prevalence of dysphagia after orthopedic surgery was 16–32 %. • Factors related to postoperative dysphagia included being older, and sarcopenia. • Non-neurogenic dysphagia present in orthopedic patients, and sarcopenia may contribute. Oropharyngeal dysphagia is one of the most prevalent health complications in older adults. The prevalence of postoperative dysphagia is expected to rise with the increasing number of older patients undergoing orthopedic surgery; however, the specific prevalence and contributing factors remain unclear. This scoping review aimed to identify the prevalence and factors related to postoperative dysphagia in older orthopedic patients. This review included studies published up to September 2022 on postoperative patients aged ≥ 60 years who underwent orthopedic surgery. We searched MEDLINE, EMBASE, CINAHL, CENTRAL, Web of Science, and Ichushi-Web. In total, 21 of the 2158 identified studies were reviewed. The studies were classified into the three categories according to the surgical site: cervical spine disease (n = 12), hip fracture (n = 7), and others (n = 2). The estimated dysphagia prevalence rates [95 % confidence interval] of cervical spine disease, hip fractures, and others were 16 % [8–27], 32 % [15–54], and 6 % [4–8], respectively. Factors related to postoperative dysphagia included cervical alignment in cervical spine disease, being older within the cohort, preoperative health status, malnutrition, and sarcopenia in hip fractures. The prevalence of postoperative dysphagia after orthopedic surgery was highest for hip fractures, followed by cervical spine and others. These results suggest non-neurogenic dysphagia in older patients undergoing orthopedic surgery and indicate that sarcopenia may contribute to postoperative dysphagia in this population. Therefore, further research should clarify the trajectory of postoperative dysphagia and the effectiveness of rehabilitation for postoperative dysphagia after orthopedic surgery.
