Dysphagia among geriatric trauma patients: A population-based study

Comprehensive assessment and treatment strategies for dysphagia in the elderly population: Current status and prospects

As the population ages, the prevalence of dysphagia among older adults is a growing concern. Age-related declines in physiological function, coupled with neurological disorders and structural changes in the pharynx associated with aging, can result in weakened tongue propulsion, a prolonged reaction time of the submental muscles, delayed closure of the laryngeal vestibule, and delayed opening of the upper esophageal sphincter (UES), increasing the risk of dysphagia. Dysphagia impacts the physical health of the elderly, leading to serious complications such as dehydration, aspiration pneumonia, malnutrition, and even life-threatening conditions, and it also detrimentally affects their psychological and social well-being. There is a significant correlation between frailty, sarcopenia, and dysphagia in the elderly population. Therefore, older adults should be screened for dysphagia to identify both frailty and sarcopenia. A reasonable diagnostic approach for dysphagia involves screening, clinical assessment, and instrumental diagnosis. In terms of treatment, multidisciplinary collaboration, rehabilitation training, and the utilization of new technologies are essential. Future research will continue to concentrate on these areas to enhance the diagnosis and treatment of dysphagia, with the ultimate aim of enhancing the quality of life of the elderly population.

Effects of Cerebellar Repetitive Transcranial Magnetic Stimulation in the Treatment of Post-Stroke Dysphagia: A Meta-Analysis and Systematic Review of Randomized Controlled Trials

INTRODUCTION

This study aimed to comprehensively evaluate the therapeutic efficacy of cerebellar repetitive transcranial magnetic stimulation (rTMS) in the rehabilitation of post-stroke dysphagia (PSD).

METHODS

Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we systematically searched PubMed, Cochrane Library, Embase, and Web of Science to identify relevant randomized controlled trials (RCTs) investigating the application of cerebellar rTMS in the treatment of PSD. Inclusion and exclusion criteria were rigorously applied during the screening process, and pertinent characteristics of the included RCTs were meticulously extracted. The I2 statistic was employed to assess heterogeneity, and meta-analysis was conducted using Stata 17 software. The Cochrane Risk of Bias 2 tool and PEDro scale were utilized to evaluate bias risk and literature quality.

RESULTS

Our analysis encompassed a total of 5 RCTs involving 673 patients with dysphagia who met the inclusion criteria. The findings indicated a significant positive impact of cerebellar rTMS when combined with traditional swallowing exercises on PSD, demonstrating superior efficacy compared to conventional swallowing exercises in isolation. Furthermore, the study revealed no statistically significant differences based on stimulation site (unilateral vs. bilateral cerebellum), stimulation mode (rTMS vs. intermittent theta-burst stimulation), and stimulation frequency (5 Hz vs. 10 Hz).

CONCLUSION

The amalgamation of cerebellar rTMS with conventional swallowing exercises demonstrates notable efficacy, surpassing the outcomes achievable with traditional exercises alone. The sustained effectiveness observed underscores the potential of cerebellar rTMS as an innovative avenue in the field of neurorehabilitation for PSD. This study contributes valuable insights into the prospect of utilizing cerebellar rTMS as an adjunctive therapeutic strategy in the management of PSD, emphasizing its relevance for further exploration and clinical application.

Assessing Knowledge, Usage, and Perceptions of the Frazier Free Water Protocol: A Pilot Study

INTRODUCTION

Dysphagia is very common among hospitalized patients and is associated with increased length of hospital stay, morbidity, and mortality. Diet restrictions for dysphagia cause dehydration and discontent. The Frazier Free Water Protocol (FFWP) was developed to improve hydration and quality of life in dysphagia patients by establishing the safety of allowing sips of water between meals. Despite these potential benefits, we hypothesized that the FFWP is not widely utilized. We sought to determine barriers to utilization by assessing the familiarity, usage, and perceptions of the FFWP among health-care providers at our institution.

METHODS

We distributed an anonymous questionnaire to a convenience sample of nurses in the hospital during daily huddles. The questionnaire was adapted from a validated framework to assess provider acceptability of health-care interventions.

RESULTS

Of the 66 surveys distributed, we had 58 completed (88%). Only 10 nurses (17%) had heard of the "FFWP" by name. For those that were familiar with the indications, benefits, and risks of giving free water to patients with dysphagia (n = 18), less than half (39%) reported doing so. No nurses that had less than 10 y of patient care experience gave water to dysphagia patients, even if they knew the indications, benefits, and risks. Similarly, less than a fifth (19%) of all nurses surveyed were comfortable giving water to dysphagia patients, but comfort increased for some if the protocol was recommended by a speech-language pathologist (33%) or physician (13%). Nursing experience of >10 y or in intensive care settings did not yield significant differences in knowledge, usage, or comfort level than those with less years or nonintensive care experience, respectively.

CONCLUSIONS

Nurses are essential to the implementation of the FFWP, yet many are unfamiliar and uncomfortable with utilizing it. Education about the protocol is necessary to improve patient outcomes and quality of life. We plan to provide targeted education about the FFWP as well as assess other members of the health-care team, in an attempt to increase utilization of the protocol and improve dysphagia management.

Evaluating the effectiveness of video-game based swallowing function training in patients with dysphagia: study protocol for a randomized controlled trial

BACKGROUND

Dysphagia can lead to serious complications such as aspiration and aspiration pneumonia, timely and effective rehabilitation training can improve the swallowing function of patients. However, the conventional rehabilitation training methods used in clinical settings have shortcomings such as poor adherence of patients. We present the study design of a randomized controlled trial that evaluated whether video-game based swallowing rehabilitation training can effectively improve swallowing in patients with dysphagia and whether it has additional benefits compared with conventional training methods to improve swallowing function and training compliance among patients with dysphagia.

METHODS

A randomized controlled trial with 4 weeks of intervention and 4 weeks of follow-up will be conducted in a rehabilitation center in Beijing, China. We will enroll 78 patients aged 18-80 years with dysphagia. Participants will be randomly assigned to the experimental group (video-game based swallowing function training) and the control group (conventional swallowing function training). All participants will receive 30 min of training per day, 5 times per week, for a total of 4 weeks. The primary outcome is swallowing function. Secondary outcomes include patients' quality of life, training compliance, and training satisfaction. Outcomes are assessed at baseline (pre-treatment), 4 weeks of treatment (post-treatment), and 8 weeks (follow-up), and the assessor is not aware of the participants' grouping.

DISCUSSION

The protocol describes a new rehabilitation training method for dysphagia, which involves participant eligibility recruitment, recruitment strategies, and data analysis plan. The results of the study will inform the rehabilitation training and clinical care management of swallowing function in patients with dysphagia.

Benefits and harms of oral anticoagulants for atrial fibrillation in nursing home residents with advanced dementia

BACKGROUND

Approximately 20% of older persons with dementia have atrial fibrillation (AF). Nearly all have stroke risks that exceed the guideline-recommended threshold for anticoagulation. Although individuals with dementia develop profound impairments and die from the disease, little evidence exists to guide anticoagulant discontinuation, and almost one-third of nursing home residents with advanced dementia and AF remain anticoagulated in the last 6 months of life. We aimed to quantify the benefits and harms of anticoagulation in this population.

METHODS

Using Minimum Data Set and Medicare claims, we conducted a retrospective cohort study with 14,877 long-stay nursing home residents aged ≥66 between 2013 and 2018 who had advanced dementia and AF. We excluded individuals with venous thromboembolism and valvular heart disease. We measured anticoagulant exposure quarterly, using Medicare Part D claims. The primary outcome was all-cause mortality; secondary outcomes were ischemic stroke and serious bleeding. We performed survival analyses with multivariable adjustment and inverse probability of treatment (IPT) weighting.

RESULTS

In the study sample, 72.0% were female, 82.7% were aged ≥80 years, and 13.5% were nonwhite. Mean CHA2 DS2 VASC score was 6.19 ± 1.58. In multivariable survival analysis, anticoagulation was associated with decreased risk of death (HR 0.71, 95% CI 0.67-0.75) and increased bleeding risk (HR 1.15, 95% CI 1.02-1.29); the association with stroke risk was not significant (HR 1.08, 95% CI 0.80-1.46). Results were similar in models with IPT weighting. While >50% of patients in both groups died within a year, median weighted survival was 76 days longer for anticoagulated individuals.

CONCLUSION

Persons with advanced dementia and AF derive clinically modest life prolongation from anticoagulation, at the cost of elevated risk of bleeding. The relevance of this benefit is unclear in a group with high dementia-related mortality and for whom the primary goal is often comfort.

The role of pH-impedance monitoring in swallowing disorders

PURPOSE OF REVIEW

To review the current evidence about the usefulness and the place of pH study in the management of patients with swallowing disorders.

RECENT FINDINGS

Gastroesophageal reflux disease (GERD) and laryngopharyngeal reflux (LPR) are found in approximately 30% of patients with esophageal or oropharyngeal dysphagia. Patients with suspected GERD may benefit from gastrointestinal endoscopy and proton pump inhibitors according to guidelines. The diagnosis of LPR in patients with oropharyngeal dysphagia is more controversial because there are no gold standard and diagnostic guidelines. The clinical diagnosis based on empirical therapeutic trial is a reasonable first-line strategy, but many dysphagic patients should not respond to treatment. These patients require hypopharyngeal-esophageal multichannel intraluminal impedance-pH monitoring (HEMII-pH), which is the most effective examination providing important information on GERD and LPR features. At the HEMII-pH, GERD patients often report upright (daytime) and supine (nighttime) liquid acid esophageal events with significant esophageal distal acid exposure time. LPR patients have more frequently upright (daytime) gaseous weakly acid or nonacid pharyngeal reflux events without distal esophageal acid exposure abnormalities in many times. The features of reflux at the HEMII-pH may indicate a personalized treatment for dysphagic patients combining proton pump inhibitors, alginate/magaldrate or gastroprokinetic in cases of esophageal dysmotility.

SUMMARY

GERD and LPR are prevalent causes of dysphagia. The large number of reflux patients who do not respond to empirical treatment makes important the awareness of otolaryngologists about pH-impedance monitoring indication, features, and interpretation.
