Filter by:Randomized clinical study with a control group for assessing the decrease in the incidence of pneumonia, in a 12-month follow-up, in older people with cognitive impairment, risk of bronchial aspiration, risk of malnutrition and dependence to perform basic activities of daily living, through the design and implementation of an educational program. to the caregivers of these patients.
Oropharyngeal sensory impairments are a potential target for treatment of oropharyngeal dysphagia (OD) in older patients. We previously found acute administration of TRP sensory stimulants improved VFS signs and swallow response. We hypothesized that sub-acute administration of TRP pharyngeal sensory stimulants, would improve cortical neuroplasticity and will lead into a faster and stronger swallow response, however desensitization of TRP receptors may occur. Therefore, the aim of the present study was to assess the biomechanical (Videofluoroscopy) and neurophysiological (pharyngeal sensory evoked potentials -PSEPs- and motor-evoked potentials (MEPs)) effect of 2 week treatment with TRP agonists in older patients with OD. Design: 150 older (>70yr) patients with OD will be included in a Randomized Control Trial assessing the effect of oral administration of either: a) capsaicin (TRPV1); b) piperine (TRPV1/TRPA1) c) cinnamaldehyde (TRPA1); d) citric acid (ASIC3); e) capsaicin+citric acid (TRPV1/ASIC3); and f) placebo (Control). Measurements: 1) VFS signs of safety and efficacy of swallow and timing and extent of swallow response; 2) Latency, amplitude and cortical representation of PSEP and MEP; 3) Substance P concentration in saliva by ELISA as a marker of peripheral stimulation. Results from this study might help to develop new and effective pharmacological treatments for older dysphagic patients, from compensation to recovery of swallow function.
Background: Oropharyngeal dysphagia (OD) is a common complication in/post ICU patients that have been with intubation/mechanical ventilation or with tracheotomies or NG tubes, in patients with acute respiratory infection/pneumonia/respiratory insufficiency with a severe disease needing high concentration of oxygen or noninvasive mechanical ventilation and also in patients discharged from acute hospitals to rehabilitation centers, nursing homes or other facilities. All these situations are common for COVID-19 patients that are currently filling our hospitals due to the pandemic expansion of SARS-CoV-2. OD is associated to prolonged hospitalization, dehydration and severe nutritional and respiratory complications -aspiration pneumonia-, hospital readmissions and mortality. Aim: to assess the prevalence of OD and nutritional risk in these patients and to know their needs of compensatory treatment following the application of an early intervention, and to assess whether OD and malnutrition are indicators of poor prognosis for COVID-19 patients. Methods: prospective study in which we will use the volume-viscosity swallowing test (V-VST) to assess the prevalence of OD, and NRS2002 to assess the nutritional risk in admitted patients with confirmed COVID-19 at the Consorci Sanitari del Maresme, Catalonia, Spain. We will register also results of the EAT-10, nutritional status, the needs of compensatory treatments of these patients following an early intervention with fluid and nutritional adaptation and use of nutritional supplements. We will also collect other clinical variables from medical history of the patient related to hospitalization and we will follow the clinical complications and nutritional status at 3 and 6 months follow up.
Investigator initiated prospective study to determine whether use of Continuous Positive Airway Pressure (CPAP) can improve the swallow function in patients who underwent total laryngectomy and are experiencing difficulty swallowing
This clinical trial aims to test the validity of a two-item swallowing screen and to examine the effects of the Swallowing and Oral-Care (SOC) Program on resumption of oral intake, incidence of penetration and aspiration, and incidence of pneumonia in adult patients who successfully extubated after ≥ 48 hours of endotracheal intubation.
The study is designed to explore the effectiveness of non-invasive cerebellar stimulation to enhance motor plasticity in the cortex after stroke. The investigators have shown that the human cerebellum is strongly activated during the act of swallowing and when stimulated with single TMS pulses can strongly facilitate the corticobulbar projection to the pharynx in humans. More recently the investigators have identified the most relevant frequency of stimulation of the cerebellum that can produce longer term excitation in the human swallowing motor system. The investigators therefore believe that the potential for cerebellar stimulation in improving swallowing is much greater than other methods for two reasons. Firstly, previous work has shown that unlike successful recovery of hand/arm function which relies on restoring activity in the stroke hemisphere, recovery of swallowing function relies on increased excitability in intact projections from the non-stroke hemisphere. The investigators believe that methods that can enhance these undamaged pathways have a greater chance of inducing recovery in the human swallowing system in unilateral stroke. Additionally cerebellar stimulation produces very high levels of corticobulbar excitation it may also have the advantage of improving dysphagia in posterior fossa strokes. Second, the human cerebellum is relatively easy to target and stimulate and has reduced risk of inducing unwanted effects (such as seizures) which as a consequence makes cerebellar stimulation a more pragmatic method for delivering therapeutic neurorehabilitation to dysphagic stroke patients compared to other more complex/riskier methods. A final factor is that the investigators have developed a "virtual lesion" model of swallowing dysfunction in healthy volunteers which can be reversed quite successfully with other neuro-stimulation protocols. The investigators can therefore use this model to test the effectiveness of cerebellar stimulation protocols (ipsilateral and contralateral cerebellar sites) before choosing the most effective side to apply stimulation in a proof of principle trial/study in a small group of sub-acute dysphagic patients. The hypotheses are that cerebellar TMS will: i. Reverse the brain inhibition and behavioural dysfunction following a virtual lesion model of disrupted swallowing in healthy brain (phase 1); ii. Reduce the degree of aspiration in acute dysphagia after a stroke (phase 2).
The purpose of this trial is to design, implement and evaluate the effect of a nutritional intervention in patients with Oropharyngeal Dysphagia on body composition and oral intake of energy and protein.
The purpose of this study is to apply a minimal-massive intervention (minimal recommendations to maximal number of patients) to elderly (>70 years) hospitalized patients with oropharyngeal dysphagia (OD). The intervention will consist of early screening and assessment of OD, malnutrition and oral hygiene. Patients will be given recommendations for adaptation of volume and viscosity of fluids, nutritional support and good oral hygiene practices and followed at 3, 6, 9 and 12 months after discharge. In every point of the follow-up period, patients will be re-evaluated to adjust recommendations and to verify their compliance with the treatment. The objectives of the intervention are to have an impact on complications related to OD (avoid impaired safety alterations and improve nutritional and oral health status and reduce) and to reduce readmissions, readmissions for pneumonia and morbimortality.
Swallowing is a complex phenomenon that allows oral feeding while protecting the airway. It involves many brain areas, including primary motor and sensory areas. Its dysfunction, called oropharyngeal dysphagia is present in approximately 60% of patients with a stroke. In this case, it is conventionally translated by a swallow response time delay of the swallowing reflex. Pathophysiology of dysphagia is explained by impairment of the dominant swallowing, function that representation center is bi-hemispheric but asymmetric (Hamdy, 1997). Half of patients with a stroke supra-tentoriel with oropharyngeal dysphagia (about 55 % of strokes) regain normal swallowing in a few weeks ( Barer, 1989). Mechanisms that determine the recovery appear to be related to a reorganization of the motor cortex intact. Patients who retain disorders are those who have not cortical reorganization. With this in mind a team used different methods known to modulate brain plasticity, which electrotherapy with an application endo- pharyngeal sensory threshold. This stimulation increases the excitability of the cortico- bulbar reflex, which improves swallowing function in the clinical application. The hypothesis of this work is that the transcutaneous electrical stimulation applied submental, noninvasive technique, would also have an impact on cortical plasticity may explain the improved coordination of swallowing observed in earlier studies (Verin , 2011) ( Gallas , 2010).
The aim of this study is to test the hypothesis that rTMS on the dominant swallowing hemisphere is able to modify swallowing coordination.
