Clinical Practices and Opinions toward Gastrostomy Use in Patients with Atypical Parkinsonian Syndromes: A National Survey in the UK.

Background: Severe dysphagia poses a significant challenge for clinicians regarding feeding tube choices, practices, and timing due to a lack of evidence-based guidance.

Objectives: To assess national clinical practices and opinions on gastrostomy use in patients with atypical parkinsonian syndromes (APS) across the UK.

Methods: Online survey was administered to clinicians and allied health professionals regarding availability of services, current use, perceived advantages, and problems associated with gastrostomy insertion.

Frequency and outcomes of gastrostomy insertion in a longitudinal cohort study of atypical parkinsonism.

Background: Multiple system atrophy (MSA), progressive supranuclear palsy (PSP) and corticobasal syndrome (CBS) show a high prevalence and rapid progression of dysphagia, which is associated with reduced survival. Despite this, the evidence base for gastrostomy is poor, and the optimal frequency and outcomes of this intervention are not known. We aimed to characterise the prevalence and outcomes of gastrostomy in patients with these three atypical parkinsonian disorders.

Worth a try or a last resort: Healthcare professionals' experiences and opinions of above cuff vocalisation.

Background: Above cuff vocalisation (ACV) involves the application of an external flow of air via the subglottic port of a tracheostomy. ACV can facilitate vocalisation and may improve swallowing and quality of life for patients with a tracheostomy. A recent systematic review highlighted the limited evidence available for the acceptability, effectiveness, safety or optimal implementation of ACV.

Detecting Minor Symptoms of Parkinson's Disease in the Wild Using Bi-LSTM with Attention Mechanism.

Parkinson's disease (PD) is a neurodegenerative disorder characterized by motor and nonmotor impairment with various implications on patients' quality of life. Since currently available therapies are only symptomatic, identifying individuals with prodromal, preclinical, or early-stage PD is crucial, as they would be ideal candidates for future disease-modifying therapies. Our analysis aims to develop a robust model for accurate PD detection using accelerometer data collected from PD and non-PD individuals with mild or no tremor during phone conversations.

The assessment of dysphagia after stroke: state of the art and future directions.

Dysphagia is a major complication following an acute stroke that affects the majority of patients. Clinically, dysphagia after stroke is associated with increased risk of aspiration pneumonia, malnutrition, mortality, and other adverse functional outcomes. Pathophysiologically, dysphagia after stroke is caused by disruption of an extensive cortical and subcortical swallowing network.

Developmental Feeding Stages and Their Impact on Child Feeding Behavior.

Objectives: Previous research has shown that critical periods of feeding skills development exist and feeding problems can arise in children due to delays in attaining feeding developmental milestones. This study aims to delineate the transitional process of feeding development in healthy children and children with gastrointestinal diseases (GIDs) and to examine the relationship between feeding milestones and the appearance of later feeding problems.

Methods: A cross-sectional case-control study among 711 healthy Greek children and 119 children with GID, aged 2-7 years.

The adaptation of the Leeds Post-Extubation Dysphagia Screen: Lessons learned during the COVID-19 pandemic.

Introduction: Post-extubation dysphagia (PED) can have serious consequences for critically unwell patients. COVID-19 has resulted in an increasing need for a PED screen in order to effectively identify patients and mitigate risk, whilst balancing under-resourced services. Online training provides the advantage of reducing time pressures on staff and supporting social distancing.

A feasibility pilot study of the effects of neurostimulation on swallowing function in Parkinson's Disease [version 2; peer review: 1 approved, 3 approved with reservations, 1 not approved].

Introduction: Dysphagia often occurs during Parkinson's disease (PD) and can have severe consequences. Recently, neuromodulatory techniques have been used to treat neurogenic dysphagia. Here we aimed to compare the neurophysiological and swallowing effects of three different types of neurostimulation, 5 Hertz (Hz) repetitive transcranial magnetic stimulation (rTMS), 1 Hz rTMS and pharyngeal electrical stimulation (PES) in patients with PD.

Reliability of the Penetration-Aspiration Scale and Temporal and Clearance Measures in Poststroke Dysphagia: Videofluoroscopic Analysis From the Swallowing Treatment using Electrical Pharyngeal Stimulation Trial.

Purpose: Information on reliability of outcome measures used to assess the effectiveness of interventions in dysphagia rehabilitation is lacking, particularly when used by different research groups. Here, we report on reliability of the penetration-aspiration scale (PAS) and temporal and clearance measures, determined using videofluoroscopy.

Method: Secondary analysis used videofluoroscopies from the Swallowing Treatment using Electrical Pharyngeal Stimulation trial in subacute stroke.

European Stroke Organisation and European Society for Swallowing Disorders guideline for the diagnosis and treatment of post-stroke dysphagia.

Post-stroke dysphagia (PSD) is present in more than 50% of acute stroke patients, increases the risk of complications, in particular aspiration pneumonia, malnutrition and dehydration, and is linked to poor outcome and mortality. The aim of this guideline is to assist all members of the multidisciplinary team in their management of patients with PSD. These guidelines were developed based on the European Stroke Organisation (ESO) standard operating procedure and followed the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach.

Falls risk is predictive of dysphagia in Parkinson's disease.

Objective: Evaluate the relationship between falls, freezing of gait, and swallowing disturbance in Parkinson's disease (PD).

Background: Dysphagia is a common symptom in PD, and is often thought of as an axial feature along with falls and gait disturbance. It is of interest to examine the relationship between these symptoms in PD, given the possibility of shared pathophysiology due to non-dopaminergic and extranigral dysfunction.

Reversal of the effects of focal suppression on pharyngeal corticobulbar tracts by chemesthesis coupled with repeated swallowing.

Background: Previous reports suggested the potential benefit of chemesthesis in the form of carbonated water (CW) integrated within dysphagia rehabilitation protocols. Here, we examined the effects of CW within a repeated swallowing protocol following focal suppression to pharyngeal cortical representation as a prelude to its application in dysphagic patients.

Methods: Fourteen healthy volunteers participated in a 3-arm study.

Consensus on the treatment of dysphagia in Parkinson's disease.

Background: Dysphagia is common in Parkinson's disease (PD). The effects of antiparkinsonian drugs on dysphagia are controversial. Several treatments for dysphagia are available but there is no consensus on their efficacy in PD.

Determining the Prevalence, Implementation Approaches, and Opinions of Above Cuff Vocalization: A Survey of Health Care Professionals.

Objective: To conduct an international survey to investigate the use of above cuff vocalization (ACV) and how practice and opinion differs.

Design: Observational, cross-sectional online survey.

Setting: Critical care, acute, rehabilitation, long-term care, and community.

A multinational consensus on dysphagia in Parkinson's disease: screening, diagnosis and prognostic value.

Background: Parkinson's disease (PD) is a neurodegenerative disorder characterized by a combination of motor and non-motor dysfunction. Dysphagia is a common symptom in PD, though it is still too frequently underdiagnosed. Consensus is lacking on screening, diagnosis, and prognosis of dysphagia in PD.

Effects of Pharyngeal Electrical Stimulation on Swallow Timings, Clearance and Safety in Post-Stroke Dysphagia: Analysis from the Swallowing Treatment Using Electrical Pharyngeal Stimulation (STEPS) Trial.

Swallowing impairment (dysphagia) post-stroke results in poorer outcomes. Pharyngeal electrical stimulation (PES) is a potential treatment for post-stroke dysphagia. In a post hoc analysis, we investigated PES using videofluoroscopy swallow studies (VFSS) from the STEPS trial incorporating multiple measures of safety (penetration aspiration scale-PAS), speed and duration (timing), and efficiency (clearance), as opposed to the original trial which only measured PAS scores.

Evidence for Above Cuff Vocalization in Patients With a Tracheostomy: A Systematic Review.

Objectives/hypothesis: To determine how above cuff vocalization (ACV) is implemented in clinical practice, to identify what evidence exists on the effectiveness and safety of ACV, and to evaluate the acceptability of ACV.

Study Design: Systematic review.

Methods: A literature search was conducted in eight databases (MEDLINE, Embase, AMED, CINAHL, Cochrane Library, PsycINFO, Scopus, and Web of Science) in May 2019 and updated in June 2020.

ESSD Commentary on Dysphagia Management During COVID Pandemia.

Since the World Health Organization declared the COVID-19 pandemic a Global Public Health Emergency, experts in swallowing are seeking guidance on service delivery and clinical procedures. The European Society for Swallowing Disorders provides considerations to support experts in swallowing disorders in clinical practice. During the COVID-19 pandemic, assessment and treatment of patients with oropharyngeal dysphagia should be provided, while at the same time balancing risk of oropharyngeal complications with that of infection of patients and healthcare professionals involved in their management.

Pathophysiology of Swallowing Dysfunction in Parkinson Disease and Lack of Dopaminergic Impact on the Swallow Function and on the Effect of Thickening Agents.

(1) Background: The effect of dopaminergic treatment on swallowing response in patients with Parkinson's disease (PD) suffering oropharyngeal dysphagia (OD) is not understood. Aim: To characterize OD pathophysiology in PD and to assess whether dopaminergic states affect swallow function and the effect of thickeners. (2) Methods: Fifty patients with PD (40 evaluated in OFF/ON states) and 12 healthy volunteers (HVs) were evaluated with videofluoroscopy (VFS) to assess the swallowing biomechanics and kinematics of the swallowing response at three different shear-viscosities (<50, 120, and 4000 mPa·s); (3) Results: Patients presented a mean age of 70.

Short-term neurophysiological effects of sensory pathway neurorehabilitation strategies on chronic poststroke oropharyngeal dysphagia.

Background: Neurorehabilitation strategies for chronic poststroke (PS) oropharyngeal dysphagia (OD) have been mainly focused on the neurostimulation of the pharyngeal motor cortex with only marginal effects. In contrast, treatments targeting the PS oropharyngeal sensory pathway dysfunction offer very promising results, but there is little knowledge on the underlying mechanisms. We aimed to explore the neurophysiological mechanisms behind the effect of three sensory neurostimulation strategies.

Psychometric assessment and validation of the dysphagia severity rating scale in stroke patients.

Post stroke dysphagia (PSD) is common and associated with poor outcome. The Dysphagia Severity Rating Scale (DSRS), which grades how severe dysphagia is based on fluid and diet modification and supervision requirements for feeding, is used for clinical research but has limited published validation information. Multiple approaches were taken to validate the DSRS, including concurrent- and predictive criterion validity, internal consistency, inter- and intra-rater reliability and sensitivity to change.
