Evaluation of volitional and reflexive swallowing in elderly patients with a history of pneumonia

Effects of Olfactory Stimulation on Swallowing Function in Taiwanese Older Adults

This pretest-posttest pilot study was to examine the effects of how olfactory stimulation (OS) influenced swallowing function in older adults. Forty-four community-dwelling older residents (24 OS & 20 control) from southern Taiwan were recruited. Participants in the intervention group administered pre-meal OS using odor and flavor inhalation. The study found that physiological responses for different food textures significantly differed between groups at post-test (p ≤ .02). Within the experimental group, swallowing function, and individual satisfaction showed significant differences before and after the odor inhalation over time (p < .01, ηp2 = 0.16–0.33). An individual’s satisfaction to their own swallowing capacity was largely enhanced by the significant interaction between time and group (F[1, 42] = 11.34, p = .002, ηp2 = 0.21), but not for physiological response to OS and swallowing function. The results suggest OS may be advantageous to improving physiological response to OS, swallowing function and satisfaction with swallowing capacity in older adults.

Feasibility of balloon endoscope-assisted endoscopic retrograde cholangiopancreatography for the elderly

Background and study aims  Endoscopic retrograde cholangiopancreatography (ERCP) for patients with surgically altered anatomy is challenging. Recently, balloon endoscopy has been shown to facilitate ERCP for this population with a high technical success rate, but adverse events (AEs) are not uncommon. Compared to non-elderly patients, elderly patients may be at higher risk of AEs due to underlying comorbidities. The current study aimed to evaluate the feasibility of balloon endoscope-assisted ERCP (BE-ERCP) for the elderly. Patients and methods  We retrospectively identified patients who underwent BE-ERCP between January 2010 and September 2019. For patients who underwent multiple procedures during the study period, the first session was analyzed. Early AEs associated with BE-ERCP were compared between elderly (≥ 75 years) and non-elderly patients. Results  A total of 1,363 BE-ERCP procedures were performed, and 568 patients (211 elderly and 357 non-elderly) were included for the analyses. Technical success rates were high in both the elderly and non-elderly groups (80 % vs. 80 %, respectively). The rates of early AEs were similar between the groups (12 % vs. 9.0 % in the elderly and non-elderly group, respectively; P  = 0.31). The mltivariable-adjusted odds ratio for early AEs comparing elderly to non-elderly patients was 1.36 (95 % confidence interval, 0.74-2.51; P  = 0.32). Specifically, we did not observe between-group differences in rates of gastrointestinal perforation (2.4 % vs. 2.8 % in elderly and non-elderly groups, respectively; P  = 0.99) and aspiration pneumonia (1.9 % vs. 0.6 %, P  = 0.20). Conclusions  BE-ERCP is a feasible procedure for elderly individuals with surgically altered anatomy.
