tDCS for Dysphagia Associated to Brainstem Stroke

The aim of the study is to investigate the effect of anodal transcranial direct current stimulation applied over the pharyngeal motor area in 60 dysphagic patients with acute isolated brainstem stroke. Thirty patients will undergo stimulation on the pharyngeal area contralateral to the side of brainstem lesion, and 30 patients will receive sham stimulation over the contralateral area, for 4 consecutive days. Patients will be re-evaluated after 4 consecutive days of stimulation. Primary outcome: The Penetration/Aspiration Scale after 4 consecutive days of stimulation. Secondary outcomes: changes in electromyographic parameters and pharyngeal cortical motor evoked potentials, changes in the Dysphagia Severity Rating Scale (DSRS), in the Functional Oral Intake Scale (FOIS), and in the "Dysphagia Limit Test", after 4 consecutive days of stimulation.

Detection of Neuromuscular Complications in Critically Ill Patients

Dysphagia and the intensive care unit-acquired weakness (ICU-AW) are common and outcome-relevant neuromuscular complications in critically ill patients, especially after prolonged mechanical ventilation, sepsis and multi-organ failure. However, the impact of these two complications on the clinical course of critically ill patients needs further investigation. Furthermore, the standard diagnostic procedure to detect and grade the acquired dysphagia using the fiberoptic endoscopic evaluation of swallowing (FEES) and the Medical Research Council sum score (MRC-ss) to detect ICU-AW are time-consuming and strongly dependent on patient compliance. An early and easy-to-use detection of these neuromuscular complications is currently difficult to be achieved in this patient population. Neuromuscular ultrasound (NMUS) and the measurement of neuromuscular damage blood biomarkers became increasingly interesting for clinical researchers in the recent years due to their broad availability and their simple and non-invasive application. However, the value of these new diagnostic tests to evaluate dysphagia and ICU-AW needs to be verified.

Non-invasive Markers of Esophageal Function in Adults

The investigator proposes to study electrical activity reflective of esophageal motility in adults noninvasively by the use of multichannel electroesophagogram (EESG) and magnetoesophagogram (MESG) recordings.

Comparison of Zenker's Diverticulum Treatment Using Peroral Endoscopic Myotomy and Flexible Endoscopy Septotomy.

The Zenker's or pharyngo-esophageal diverticulum is an acquired sac-like outpouching of the mucosa and submucosa layers located dorsally at the pharyngoesophageal junction through Killian's dehiscence. It is the most common type of oesophageal diverticula and typically occurs in middle-aged and elderly patients. Patients have a significantly reduced quality of life index and numerous complications. Treatment is recommended for symptomatic patients and considering the aetiopathogenesis of the disease demands myotomy of the cricopharyngeal muscle. Myotomy may be pursued through either open surgical or endoscopic techniques. There is a novel technique, called the peroral endoscopic myotomy (Z-POEM) for treatment of Zenker's diverticulum. The ZIPPY trial designed as prospective, international, multicenter, double-blind, randomized study which will be carried out by experienced endoscopists. The aim of this study will be to evaluate the results of Zenker's diverticulum treatment using peroral endoscopic myotomy and to compare its efficacy and safety to flexible endoscopy septotomy. Patients at least 18 years old with symptomatic Zenker's diverticulum diagnosed on the basis of endoscopic and radiological examinations will be enrolled.

Slow-Stream Expiratory Muscle Strength Training for Veterans With Dysphagia Living in Long-term Care

Sunnybrook Veterans Centre (VC) is a long-term care (LTC) facility with many elderly residents living with swallowing disorders who are at high risk of developing pneumonia from aspirating food/liquid into their lungs. Expiratory muscle strength training (EMST) using a hand-held resistance device over a four week intensive program has been shown to have promising results in improving cough function and reducing aspiration during swallowing in older, community-dwelling adults. The purpose of this study is to explore whether a modified slow-stream protocol of EMST over eight weeks is an effective therapy for improving swallowing safety and lung clearance in elderly VC residents with swallowing disorders. Before and after the eight week therapy program, we will measure participants' cough under spirometry, swallowing under videofluoroscopy, and their swallowing-related quality of life and diet texture modification. A three month follow-up visit will measure swallowing-related quality of life again, as well as record incidence of respiratory tract infections requiring antibiotics in the last three months, to be compared with broader institutional data.

The Relative Effectiveness of BOLUS Versus Continuous Nasogastric Feeding After Stroke: a Proof of Principal Study

Patients with severe strokes are often unable to be take oral diet food and fluids safely because they cannot swallow effectively. Therefore, patients need to be fed via a tube placed through the nose into the stomach (nasogastric tube). Tube feeding can be given by the intermittent (bolus) method, whereby the feed is given over a short time (15 to 30 minutes), or by the continuous feeding method, where the feed is given continuously over 10-16 hours. Nasogastric feeding can be complicated by vomiting or reflux of the feed into the oesophagus causing aspiration of gastric contents into the lung and pneumonia. Nasogastric feeds can be given continuously or as bolus feeds. Healthy people eating normally take their diet in discrete meals. The human digestive system is adapted to intermittent food intake and is likely to work best if food is provided in this pattern, but the larger volume of the feed by this method may cause vomiting and aspiration. It is unclear which method is better for allowing normal digestive processes and reducing pneumonia due to aspirated feeds. There are no trials comparing these two feeding methods in patients with acute stroke. The aim of this small study is to determine if a trial comparing the two treatment approaches is feasible in patients with acute stroke, and to collect information on the effects on feed tolerance and digestion. In this study we will compare the effect of the bolus and intermittent nasogastric tube feeding on digestion and feed tolerance in 20 patients who need nasogastric feeding within 36 hours of a stroke. Patients will be randomly allocated to be given the feeds either by the bolus or by the continuous method for 7 days. During this time they will be examined every day. The study will examine how effectively food is digested by measuring the amount of feed given and the metabolic responses of the body by looking at changes in the level of blood sugar and digestive hormones. The investigators will also monitor complications such as vomiting, diarrhoea, and pneumonia. Patients will be randomly allocated to be given the feeds either by the bolus or by the continuous method for 7 days. This will provide information which will allow the investigators to design a larger definitive study to conclusively prove which method is more appropriate.

Prediction of Functional Health Status and Aspiration Using Multiple Dysphagia Scales Over 6 Months After Acute Stroke

In order to discover dysphagia scales, which shows meaningful predictability of aspiration and functional health status in patients with acute stroke, authors plan to find out more predictable indicators than existing penetration-aspiration scale (PAS) to validate their predictions and their internal and external validity over 6 months following stroke .
