Objectives To investigate the association between loss of muscle mass and aspiration pneumonia ( AP). Design Prospective observational cohort. Setting Acute geriatric hospital. Participants Individuals admitted to the hospital for AP (N = 151; mean age 85.9; 49.7% male). Measurements Appendicular skeletal muscle index ( ASMI; appendicular skeletal muscle mass divided by height squared) was used to evaluate muscle mass. Data on age, sex, body mass index, Mini Nutritional Assessment-Short Form score, Barthel Index score, Charlson Comorbidity Index score, and pneumonia severity (Japanese version of the CURB-65 (C (confusion), U (blood urea nitrogen ≥20 mg/ dL), R (respiratory rate ≥30 breaths/min), B (systolic blood pressure <90 mmHg or diastolic blood pressure ≤60 mmHg), 65 (aged ≥65) severity score (A- DROP)) were obtained. Outcomes included 30- and 90-day mortality. Results Mild, moderate, severe, and extremely severe AP were observed in 1.3%, 70.2%, 25.8%, and 2.6% of participants, respectively. On Kaplan-Meier analysis, participants in the lowest ASMI quartile for each sex were more likely to die than those in the other quartiles (log-lank test P = .005). Multivariate logistic analyses showed that ASMI and A- DROP were independent predictors of 90-day mortality; only A- DROP was a significant predictor of 30-day mortality ( P < .001). Cox regression analysis also showed that the first ASMI quartile was independently associated with mortality (hazard ratio = 2.19; 95% confidence interval = 1.06-4.52; P = .03). Conclusion Low muscle mass is a potential predictor of long-term mortality in individuals with AP. Prospectively preventing muscle mass deterioration may be beneficial for recovery from AP in older adults. [ABSTRACT FROM AUTHOR]

Objectives To verify the reliability and validity and develop an English version of an instrument (Kuchi-Kara Taberu Index ( KT Index)) to comprehensively assess and intervene in problems with eating and swallowing. Design Multicenter cross-sectional study. Setting Nursing homes. Participants Individuals aged 65 and older (mean age 88.3 ± 6.8; 80.0% female) who had lived in a nursing home for longer than 1 month (N = 115). Measurements The KT index consisted of 13 items: desire to eat, overall condition, respiratory condition, oral condition, cognitive function while eating, oral preparatory and propulsive phases, dysphagia severity, position and endurance while eating, eating, daily life, food intake level, food modification, and nutrition. Weighted kappa coefficients, Cronbach alpha, and Spearman rank correlation coefficients were determined. Results Weighted kappa values in the inter- and intrarater reliability tests ranged from 0.54 to 0.96 and 0.68 to 0.98, respectively. Cronbach alpha was 0.892. Spearman rank correlation coefficients (r) between the total KT index and external criteria were determined (Functional Oral Intake Scale, r = 0.790; Barthel Index, r = 0.830; Mini Nutritional Assessment Short Form, r = 0.582; Cognitive Performance Scale, r = −0.673; all P < .001). Similar correlations were observed when some items related to each external criterion were removed from the total KT index. Translation-retranslation procedures were conducted to develop an English version of the KT index. Conclusion The study provided evidence of the reliability and validity of the KT index and developed an English version. Future studies regarding validation of health-related quality of life indices and their effect on clinical courses of eating and swallowing conditions are needed. [ABSTRACT FROM AUTHOR]
