Review
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.
OBJECTIVE
To conduct a systematic review of the literature and to define consensus statements on the treatment of dysphagia in PD and related nutritional management.
METHODS
A multinational group of experts in the field of neurogenic dysphagia and/or Parkinson's disease conducted a systematic evaluation of the literature and reported the results according to PRISMA guidelines. The evidence from the retrieved studies was analyzed and discussed in a consensus conference organized in Pavia, Italy, and the consensus statements were drafted. The final version of statements was subsequently achieved by e-mail consensus.
RESULTS
The literature review retrieved 64 papers on treatment and nutrition of patients with PD and dysphagia, mainly of Class IV quality. Based on the literature and expert opinion in cases where the evidence was limited or lacking, 26 statements were developed.
CONCLUSIONS
The statements developed by the Consensus panel provide a guidance for a multi-disciplinary treatment of dysphagia in patients with PD, involving neurologists, otorhinolaryngologists, gastroenterologists, phoniatricians, speech-language pathologists, dieticians, and clinical nutritionists.

Review
Oropharyngeal dysphagia is common post-stroke and can have serious consequences for patients. Understanding dysphagia recovery is critically important to inform prognostication and support patients and professionals with care planning. This systematic review was undertaken to identify clinical predictors of dysphagia recovery post-stroke. Online databases (EMBASE, Scopus, Web of Science, PubMed, CINAHL, and Cochrane) were searched for studies reporting longitudinal swallowing recovery in adults post-stroke. Dysphagia recovery was defined as improvement measured on a clinical swallowing scale or upgrade in oral and/or enteral feeding status by the end of the follow-up period. The search strategy returned 6598 studies from which 87 studies went through full-text screening, and 19 studies were included that met the eligibility criteria. Age, airway compromise identified on instrumental assessment, dysphagia severity, bilateral lesions, and stroke severity were identified as predictors of persistent dysphagia and negative recovery in multiple logistic regression analysis. The available literature was predominated by retrospective data, and comparison of outcomes was limited by methodological differences across the studies in terms of the choice of assessment, measure of recovery, and period of follow-up. Future prospective research is warranted with increased representation of haemorrhagic strokes and uniform use of standardized scales of swallowing function.

Review
PURPOSE
Community-acquired pneumonia (CAP) is highly common across the world. It is reported that over 90% of CAP in older adults may be due to aspiration. However, the diagnostic criteria for aspiration pneumonia (AP) have not been widely agreed. Is there a consensus on how to diagnose AP? What are the clinical features of patients being diagnosed with AP? We conducted a systematic review to answer these questions.
METHODS
We performed a literature search in MEDLINE, EMBASE, CINHAL, and Cochrane to review the steps taken toward diagnosing AP. Search terms for "aspiration pneumonia" and "aged" were used. Inclusion criteria were: original research, community-acquired AP, age ≥ 75 years old, acute hospital admission.
RESULTS
A total of 10,716 reports were found. Following the removal of duplicates, 7601 were screened, 95 underwent full-text review, and 9 reports were included in the final analysis. Pneumonia was diagnosed using a combination of symptoms, inflammatory markers, and chest imaging findings in most studies. AP was defined as pneumonia with some relation to aspiration or dysphagia. Aspiration was inferred if there was witnessed or prior presumed aspiration, episodes of coughing on food or liquids, relevant underlying conditions, abnormalities on videofluoroscopy or water swallow test, and gravity-dependent distribution of shadows on chest imaging. Patients with AP were older, more frailer, and had more comorbidities than in non-AP.
CONCLUSION
There is a broad consensus on the clinical criteria to diagnose AP. It is a presumptive diagnosis with regards to patients' general frailty rather than in relation to swallowing function itself.

Review
BACKGROUND
Stroke can affect people's ability to swallow, resulting in passage of some food and drink into the airway. This can cause choking, chest infection, malnutrition and dehydration, reduced rehabilitation, increased risk of anxiety and depression, longer hospital stay, increased likelihood of discharge to a care home, and increased risk of death. Early identification and management of disordered swallowing reduces risk of these difficulties.
OBJECTIVES
Primary objective • To determine the diagnostic accuracy and the sensitivity and specificity of bedside screening tests for detecting risk of aspiration associated with dysphagia in people with acute stroke Secondary objectives • To assess the influence of the following sources of heterogeneity on the diagnostic accuracy of bedside screening tools for dysphagia - Patient demographics (e.g. age, gender) - Time post stroke that the study was conducted (from admission to 48 hours) to ensure only hyperacute and acute stroke swallow screening tools are identified - Definition of dysphagia used by the study - Level of training of nursing staff (both grade and training in the screening tool) - Low-quality studies identified from the methodological quality checklist - Type and threshold of index test - Type of reference test SEARCH METHODS: In June 2017 and December 2019, we searched CENTRAL, MEDLINE, Embase, CINAHL, and the Health Technology Assessment (HTA) database via the Centre for Reviews and Dissemination; the reference lists of included studies; and grey literature sources. We contacted experts in the field to identify any ongoing studies and those potentially missed by the search strategy.
SELECTION CRITERIA
We included studies that were single-gate or two-gate studies comparing a bedside screening tool administered by nurses or other healthcare professionals (HCPs) with expert or instrumental assessment for detection of aspiration associated with dysphagia in adults with acute stroke admitted to hospital.
DATA COLLECTION AND ANALYSIS
Two review authors independently screened each study using the eligibility criteria and then extracted data, including the sensitivity and specificity of each index test against the reference test. A third review author was available at each stage to settle disagreements. The methodological quality of each study was assessed using the Quality Assessment of Studies of Diagnostic Accuracy (QUADAS-2) tool. We identified insufficient studies for each index test, so we performed no meta-analysis. Diagnostic accuracy data were presented as sensitivities and specificities for the index tests.
MAIN RESULTS
Overall, we included 25 studies in the review, four of which we included as narratives (with no accuracy statistics reported). The included studies involved 3953 participants and 37 screening tests. Of these, 24 screening tests used water only, six used water and other consistencies, and seven used other methods. For index tests using water only, sensitivity and specificity ranged from 46% to 100% and from 43% to 100%, respectively; for those using water and other consistencies, sensitivity and specificity ranged from 75% to 100% and from 69% to 90%, respectively; and for those using other methods, sensitivity and specificity ranged from 29% to 100% and from 39% to 86%, respectively. Twenty screening tests used expert assessment or the Mann Assessment of Swallowing Ability (MASA) as the reference, six used fibreoptic endoscopic evaluation of swallowing (FEES), and 11 used videofluoroscopy (VF). Fifteen screening tools had an outcome of aspiration risk, 20 screening tools had an outcome of dysphagia, and two narrative papers did not report the outcome. Twenty-one screening tests were carried out by nurses, and 16 were carried out by other HCPs (not including speech and language therapists (SLTs)). We assessed a total of six studies as low risk across all four QUADAS-2 risk of bias domains, and we rated 15 studies as low concern across all three applicability domains. No single study demonstrated 100% sensitivity and specificity with low risk of bias for all domains. The best performing combined water swallow and instrumental tool was the Bedside Aspiration test (n = 50), the best performing water plus other consistencies tool was the Gugging Swallowing Screen (GUSS; n = 30), and the best water only swallow screening tool was the Toronto Bedside Swallowing Screening Test (TOR-BSST; n = 24). All tools demonstrated combined highest sensitivity and specificity and low risk of bias for all domains. However, clinicians should be cautious in their interpretation of these findings, as these tests are based on single studies with small sample sizes, which limits the estimates of reliability of screening tests.
AUTHORS' CONCLUSIONS
We were unable to identify a single swallow screening tool with high and precisely estimated sensitivity and specificity based on at least one trial with low risk of bias. However, we were able to offer recommendations for further high-quality studies that are needed to improve the accuracy and clinical utility of bedside screening tools.

AIM
The cause-effect relationship between anterior open bite and atypical swallowing, two frequently associated conditions, is currently not completely understood. These conditions are often accompanied by speech disorders and represent a problem for both young patients and untreated adult patients. Treatment of these complex cases may be orthodontic, logopedic therapy or both. The purpose of this review is to compare the various types of treatment to determine their effectiveness in improving skeletal condition, normalisation of muscle activity, and temporal stability.
METHODS
The present systematic review was conducted following the Preferred Reporting Items for Systematic reviews and Meta-Analyzes (PRISMA) guidelines. In order to find the most appropriate articles for inclusion, an electronic and manual search was performed using PubMed and The Cochrane Library on May 23, 2021. No language restrictions or time limits were applied. Only human studies describing cases of patients in the developmental stage of dentition, i.e., deciduous dentition or mixed dentition with an anterior open bite related to a type of swallowing with tongue interposition between the arches, undergoing three different types of treatment (orthodontic only, myofunctional/logopedic only, combined) were included.
CONCLUSION
The most effective treatment in cases of anterior open bite associated with atypical swallowing is a combination of the traditional orthodontic therapy and myofunctional therapy. Further studies are needed to devise an effective and universal logopaedic protocol to be followed in these cases.

Meta-Analysis Review
BACKGROUND
Oropharyngeal dysphagia (OD) refers to any abnormality in the physiology of swallowing in the upper gastrointestinal tract, which leads to the related clinical complications, such as malnutrition, dehydration, and sever complication, such as aspiration pneumonia, suffocation, and eventually, premature death. The previous studies indicated a various range of prevalence of OD. The present systematic review and meta-analysis aimed to standardize the global prevalence of OD in different populations.
METHODS
A systematic literature review was conducted using Embase, Scopus, PubMed, Web of Science (WoS) databases, and Google Scholar motor engine using related MeSH/Emtree and Free Text words, with no time limitation until November 2021. The heterogeneity among studies was quantified using I index and the random effects model was used, due to the high heterogeneity among the results of studies included in the meta-analysis.
RESULTS
The systematic literature search retrieved 2092 studies. After excluding the irrelevant studies, ultimately 27 articles with a sample size of 9841 were included in the meta-analysis. After combining the studies, the overall estimate of the global prevalence rate of OD was 43.8% (95% CI 33.3-54.9%) and the highest prevalence rate was estimated in Africa with 64.2% (95% CI 53.2-73.9%). Given the subgroup analysis based on the study population, the highest prevalence of OD was related to Dementia with 72.4% (95% CI 26.7-95.0%). The results of meta-regression indicated that the prevalence of OD has an increasing trend with the enhancement of year of publication and mean age.
CONCLUSION
The results of the present systematic review and meta-analysis revealed that the prevalence of OD is high in different populations and its trend has been increasing in recent years. Therefore, the appropriate strategies should be applied to reduce the prevalence of OD by finding its causation and monitoring at all levels, as well as providing feedback to hospitals.

Meta-Analysis Review
PURPOSE
To determine the effectiveness of dysphagia interventions compared to standard care in improving oral intake and reducing aspiration for adults in acute and critical care.
METHODS
We searched electronic literature for randomised and quasi-randomised trials and bibliography lists of included studies to March 2020. Study screening, data extraction, risk of bias and quality assessments were conducted independently by two reviewers. Meta-analysis used fixed effects modelling. The systematic review protocol is registered and published.
RESULTS
We identified 22 studies (19 stroke, 2 intensive care stroke and 1 general intensive care) testing 9 interventions and representing 1700 patients. Swallowing treatment showed no evidence of a difference in the time to return to oral intake (n = 33, MD (days) - 4.5, 95% CI - 10.6 to 1.6, 1 study, P = 0.15) (very low certainty) or in aspiration following treatment (n = 113, RR 0.79, 95% CI 0.44 to 1.45, 4 studies, I = 0%, P = 0.45) (low certainty). Swallowing treatment showed evidence of a reduced risk of pneumonia (n = 719, RR 0.71, 95% CI 0.56 to 0.89, 8 studies, I = 15%, P = 0.004) (low certainty) but no evidence of a difference in swallowing quality of life scores (n = 239, MD - 11.38, 95% CI - 23.83 to 1.08, I = 78%, P = 0.07) (very low certainty).
CONCLUSION
There is limited evidence for the effectiveness of swallowing treatments in the acute and critical care setting. Clinical trials consistently measuring patient-centred outcomes are needed.

Review
BACKGROUND
Dysphagia is highly prevalent condition in older adults living in nursing homes. There is also evidence indicating that aspiration is one of the major health risks for these older adults, which is more likely to result in respiratory infections, aspiration pneumonia and sudden bolus death. Evidence syntheses have demonstrated the effectiveness of interventions for prevention of aspiration among hospitalized older people. The aim of this scoping review is to describe the current spread of interventions to prevent or reduce aspiration in older adults with dysphagia with a specific focus on those who reside in nursing homes.
METHODS
The Joanna Briggs Institute methods and PRISMA-ScR guidelines were used to inform this review. MEDLINE, CINAHL, EMBASE, Cochrane Library, Joanna Briggs Institute EBP Database and Web of Science were searched for related articles from 2010 to 2020 as well as Chinese databases (CNKI, WANFANG DATA and VIP) and databases for unpublished material. A three-step search strategy was utilized, including the use of citation software to manage search results and de-duplication, abstract review and full-text review by two reviewers. Details of included studies were then extracted using a prepared data extraction tool. The resulting map was displayed in tabular form along with a narrative summary.
RESULTS
Although 637 articles were located, 19 papers were included in the final analysis. Interventions to prevent aspiration in older adults with dysphagia living in nursing homes included: more bedside evaluation, modification of dietary, creating an appropriate environment for swallowing, providing appropriate feeding assistance, appropriate posture or maneuver for swallowing, appropriate rehabilitation program, medication treatment, and stimulation treatment.
CONCLUSION
Nursing homes, particularly those in developing countries, require more support for staff training and necessary equipment. Professional interventions provided by speech and language therapists are still limited in the setting of nursing homes. Modification of dietary was the most frequently used intervention to prevent or reduce aspiration. Multi-disciplinary interventions had the best results for aspiration management, but for many nursing homes, access to such teams is limited. Nursing home residents respond well to person-centered interventions that have a comprehensive consideration of their degree of aspiration risk, health condition, individual feelings and cognitive state.

Meta-Analysis Review
Studies investigating the associations of oral function and dysphagia with frailty and sarcopenia in community-dwelling older adults are increasing; however, they have not been systematically summarized. We conducted a systematic review to investigate these associations. We searched electronic databases and synthesized relevant data using conventional (frequentist-style) and Bayesian meta-analyses. Twenty-four studies were found to be eligible for our review, including 20 cross-sectional and four prospective cohort studies. Older adults with frailty or sarcopenia had lower tongue pressure, according to the results of conventional meta-analysis (mean difference [95% confidence interval or credible interval]: -6.80 kPa [-10.22 to -3.38] for frailty and -5.40 kPa [-6.62 to -4.17] for sarcopenia) and Bayesian meta-analysis (-6.90 kPa [-9.0 to -4.8] for frailty, -5.35 kPa [-6.78 to -3.89] for sarcopenia). People with frailty had a higher odds ratio (OR) for dysphagia according to the results of conventional meta-analysis (3.99 [2.17 to 7.32]) and Bayesian meta-analysis (1.38 [0.77 to 1.98]). However, the results were inconclusive for people with sarcopenia. A prospective association could not be determined because of the lack of information and the limited number of studies. Decreased oral function and dysphagia can be important characteristics of frailty and sarcopenia in community-dwelling older adults.

Second update of a systematic review and evidence-based recommendations on texture modified foods and thickened liquids for adults (above 17 years) with oropharyngeal dysphagia.
BACKGROUND & AIMS
It is well known that oropharyngeal dysphagia (OD) challenges eating, drinking, and swallowing by penetration to the airway. In clinical practice, thickening agents in liquid and texture modified diets are used to reduce pneumonia and secure nutritional status. The scientific evidence on this OD management is, however, limited. In 2016 we updated an original clinical guideline on OD in adults. Based on the strength of the evidence of two randomized control trials (RCTs), we provided a weak clinical recommendation against the use of thickening agents for liquid and none for diet. In the hope of finding new scientific evidence, we aimed to update the clinical guideline by examining the evidence if thickening of liquid and diet 1) improve survival and quality of life, 2) reduce the occurrence of aspiration risk and pneumonia, 3) improve dehydration, nutritional status, and mealtime performance, and 4) relate to patient preferences and intervention adherence.
METHODS
We performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. We first searched systematic reviews and meta-analyses, and secondly, the primary literature of RCTs. We undertook the search in PubMed, Embase, CINAHL, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials from January 1, 2015, to May 19, 2021. The quality of the evidence was evaluated using the revised Cochrane risk-of-bias tool and the GRADE (Grading of Recommendations: Assessment, Development and Evaluation) approach.
RESULTS
One new study was included, resulting in a total of three RCTs, of which two were already included in our former guideline. The three studies focused on the thickening of liquid, but no change of the former weak recommendation against the thickening of liquid could be made due to the quality of evidence evaluation.
CONCLUSION
There is no convincing evidence that thickened liquid or texture modified diet prevents death or pneumonia nor improves the quality of life, nutritional status, or oral intake in individuals with OD. There is a need for future studies to examine the effect and discuss outcome measures in OD management with thickening agents.
