Impacts of Deep Brain Stimulation of the Globus Pallidus Internus on Swallowing: A Retrospective, Cross-Sectional Study.

Deep brain stimulation (DBS) is a common treatment for motor symptoms of Parkinson disease (PD), a condition associated with increased risk of dysphagia. The effect of DBS on swallowing function has not been comprehensively evaluated using gold-standard imaging techniques, particularly for globus pallidus internus (GPi) DBS. The objective of this retrospective, cross-sectional study was to identify differences in swallowing safety and timing kinematics among PD subjects with and without GPi DBS. We investigated the effects of unilateral and bilateral GPi DBS as well as the relationship between swallowing safety and DBS stimulation parameters, using retrospective analysis of videofluoroscopy recordings (71 recordings from 36 subjects) from electronic medical records. Outcomes were analyzed by surgical status (pre-surgical, unilateral DBS, bilateral DBS). The primary outcome was percent of thin-liquid bolus trials rated as unsafe, with Penetration-Aspiration Scale scores of 3 or higher. Secondary analyses included swallowing timing measures, relationships between swallowing safety and DBS stimulation parameters, and Dynamic Imaging Grade of Swallowing Toxicity ratings. Most subjects swallowed all boluses safely (19/29 in the pre-surgical, 16/26 in the unilateral DBS, and 10/16 in the bilateral DBS conditions). Swallowing safety impairment did not differ among stimulation groups. There was no main effect of stimulation condition on timing metrics, though main effects were found for sex and bolus type. Stimulation parameters were not correlated with swallowing safety. Swallowing efficiency and overall impairment did not differ among conditions. These results provide evidence that GPi DBS does not affect pharyngeal swallowing function. Further, prospective, investigations are needed.

Cough Correlates of Functional Swallow Outcomes in Atypical Parkinsonism.

Swallow and cough impairments lead to aspiration and reduced clearance of aspirate material. Both behaviors are impaired in Parkinson's disease, but it is unknown whether a similar relationship of dysfunction exists in forms of atypical Parkinsonism (APD). Elucidating this association in APD may lead to early, comprehensive airway protection treatment. We tested the hypotheses that swallow deficits in APD are associated with impaired cough and that airway protective dysfunction is associated with longer disease duration. Swallowing difficulty was described by 11 participants with APD. Penetration-Aspiration Scale (PAS) and DIGEST scores for thin liquid trials were extracted from medical records of videofluoroscopic swallow study reports. Voluntary and capsaicin induced-reflex cough measures of flow, volume, and timing were analyzed. While most participants did not have post-swallow residue, ~80% received abnormal PAS scores and reported swallowing difficulty. Those with abnormal PAS scores had lower voluntary cough expired volume (P = 0.037; mean rank difference = 5.0); lower reflex inspiratory flow rate (P = 0.034; mean rank difference = 5.5); and longer reflex expiratory flow rise time (P = 0.034; mean rank difference = 5.5). Higher PAS scores and reduced reflex cough volume acceleration were significantly correlated (r = -0.63; P = 0.04) and longer disease duration predicted larger voluntary cough expired volume (R2 = 0.72) and longer flow rise times (R2 = 0.47). As swallow safety worsens, so might the ability to clear the airways with effective cough in in APD; particularly with longer disease duration. Assessing cough in conjunction with swallowing is important for informing airway protection treatment plans in APD.

Investigating Parkinson's disease with dual high resolution pharyngeal manometry with impedance and videofluoroscopy.

To characterize pharyngeal function in people with Parkinson's Disease using both high resolution impedance manometry (HRIM) and videofluoroscopy (VFSS) and to explore correlations between VFSS and HRIM metrics. All participants received both VFSS and HRIM within 24 h-time window. A standard VFSS protocol (IDDSI 0: 1 mL, 3 mL, 20 mL, and 100 mL) was performed. A solid-state unidirectional catheter (36 pressure sensors) was used to acquire manometric data for triplicate swallows (IDDSI 0: 5 mL, 10 mL, 20 mL), quantitative swallow analysis was completed through Swallowtail™ and SwallowGateway™. Parameters were compared to published norms and statistical tests explored correlational associations (p < 0.05). Twenty-one participants (76% male; mean age 70 years, SD7.16) with mild-moderate severity PD were recruited with 73% reporting Eating Assessment Tool (EAT-10) scores ≥3 indicating swallow impairment. Compared to normal metrics, one third of participants had abnormally elevated hypopharyngeal contractile integral (HPCI), hypopharyngeal peak pressure, upper esophageal sphincter (UES) integrated relaxation pressure (UES IRP), and reduced UES maximum admittance. Five participants showed compromised swallow safety (Penetration-Aspiration Scale score ≥6). One third of participants had abnormal VFSS values for pharyngoesophageal segment (PES) opening duration, maximum PES opening distance, and maximum hyoid displacement measures. Some HRIM metrics had a strong correlation with pharyngeal VFSS measures (r > 0.60, p < 0.05). This study identifies early manometric signs of pharyngeal dysfunction in people with PD. The congruence of the VFSS and HRIM measures confirms the hypothesis of insidious early decline in swallow function in PD despite maintenance of airway safety (i.e., low aspiration rates).

Hemodynamic signal changes during volitional swallowing in dysphagia patients with different unilateral hemispheric stroke and brainstem stroke: A near-infrared spectroscopy study

Background and objectivesStrokes will result in decreased in cortical excitability and changed in the balance between the affected and unaffected hemispheres. Previous studies have focused on cortical changes in healthy subjects during swallowing, while they remain unknown in patients with stroke at different locations. Thus, the purpose of this study was to research cortical activation patterns of swallowing in patients with dysphagia and healthy subjects by the functional near-infrared spectroscopy (fNIRS). We also focus on the comparability of brain activation areas associated with swallowing between patients with different stroke locations and healthy subjects. Methodstotal of 104 participants were invited to our study, involving 86 patients with dysphagic unilateral hemispheric stroke and 18 age and sex matched healthy controls. The stroke patients were categorized into patients with left unilateral stroke lesions (n = 30), patients with right unilateral stroke lesions (n = 32) and patients with brainstem injury (n = 24) according to different stroke sites. All patients underwent a series of clinical swallowing function assessments, such as the Fiberoptic endoscopic dysphagia severity scale (FEDSS), penetration-aspiration scale (PAS) of Rosenbek, the gugging swallowing screen (GUSS) and the functional oral Intake scale (FOIS) after informed consent has been signed. All participants received the fNIRS system assessment. ResultsThe results showed that extensive areas of the cerebral cortex activated during the swallowing tasks in healthy participants (P < FDR 0.05). For patients with left unilateral stroke lesions, the HbO concentration were strongest over the right hemisphere (P < FDR 0.05). In addition, a less severe activation was also observed in the left hemisphere. Comparable to patients with left unilateral stroke lesions, the strongest activation during swallowing task were found in the left hemisphere in patients with right unilateral stroke lesions (P < FDR 0.05). Similarly, the right hemisphere also has activated less. In contrast, patients with brain stem injury showed more bilaterally activation patterns. ConclusionOur finding states that cortical activation areas differ between patients with different stroke locations and healthy subjects during swallowing. There was a more bilateral activation in healthy participants and patients with lesions in the brainstem while more cortical activation in unaffected hemisphere in patients with unilateral hemispheric stroke. It also provides a basis for the future treatment of dysphagia after stroke.

Longitudinal association between oral function and underweight onset among community-dwelling older adults: Role of regular self-weighing.

Regular self-weighing is effective in weight management and may help to mitigate the risk of underweight among older adults. We examined which factors of oral function are associated with a risk for underweight among community-dwelling older adults and whether regular self-weighing can mitigate that risk. This was a cohort study. Self-administered questionnaires were mailed to 7665 older adults in March 2019 (response rate 74.3%) and 7591 in March 2020 (response rate 74.7%). Among those who responded to both surveys, 3594 older adults who were not underweight in March 2019 were included (follow-up rate: 59.2%). We examined the association between dysphagia, poor masticatory function, and dry mouth and the development of underweight, and whether regular self-weighing reduced the risk for underweight. The average age±standard deviation of participants was 71.1±3.4 years. There was a significant association between swallowing difficulty and the occurrence of underweight (odds ratio=1.65, p=.012). However, this relationship did not differ significantly with regular self-weighing (p=.477). These study findings suggest that to prevent underweight among community-dwelling older adults, it is important to focus on those with poor swallowing function.

Analysis of swallowing and voice-related quality of life in patients after supracricoid partial laryngectomy

ObjectiveThis study evaluated the swallowing and voice function of laryngeal cancer patients after Supracricoid Partial Laryngectomy(SCPL), and its influence on quality of life to provide a reference for the selection of surgical methods for laryngeal cancer patients.MethodsTwenty-one patients who received SCPL between April 2015 and November 2021 were included. Each patient’s swallowing function and quality of life were assessed through fiberoptic endoscopic examination of swallowing (FEES) and the M.D. Anderson Dysphagia Inventory (MDADI). Fundamental, jitter, shimmer, maximum phonation time (MPT), and voice handicap index-10 (VHI-10) were performed to assess voice function and voice-related quality of life.ResultsThe results of the FEES of the 21 patients were as follows: the rates of pharyngeal residue after swallowing solid, semiliquid, and liquid food were 0%, 28.57%, and 38.09%, respectively; the rates of laryngeal infiltration after swallowing solid, semiliquid, and liquid food were 0%, 28.57%, and 4.76%, respectively; and aspiration did not occur in any of the patients. In the evaluation of swallowing quality of life, the mean total MDADI score was 92.6 ± 6.32. The voice function evaluation showed that the mean F0, jitter, shimmer, and MPT values were 156.01 ± 120.87 (HZ), 11.57 ± 6.21 (%), 35.37 ± 14.16 (%) and 7.85 ± 6.08 (s), respectively. The mean total VHI-10 score was 7.14 ± 4.84.ConclusionSCPL provides patients with satisfactory swallowing and voice function. The patients in this study were satisfied with their quality of life in terms of swallowing and voice. SCPL can be used as a surgical method to preserve laryngeal function in patients with laryngeal cancer.

Significant enhancement of swallowing function and oral hygiene following multidisciplinary team nursing in tongue cancer patients after radical resection.

To determine the effects of multidisciplinary team (MDT) nursing mode on the swallowing function and oral hygiene in patients after radical resection of tongue cancer (TC). The data of 88 patients with TC treated in West China School/Hospital of Stomatology, Sichuan University were analyzed retrospectively. Among them, 42 patients who received routine nursing between February 2019 and February 2020 were assigned to a control group, and 46 patients who received MDT nursing between March 2020 and February 2022 were assigned to an observation group. The two groups were compared in the changes of postoperative swallowing function and oral hygiene, postoperative swallowing-related quality of life (QoL), and the survival rate for myocutaneous flap. The risk factors affecting swallowing function were analyzed through Logistic regression. After one month of nursing, the score of swallowing function decreased notably in both groups, with notably lower score in the observation group than that in the control group (P < 0.05). The control group exhibited notably lower oral cleanliness than the observation group after nursing (P < 0.05). Additionally, a notably lower survival rate of myocutaneous flap was found in the control group than that in the observation group (P < 0.05). The QoL scores of the two groups increased notably after nursing, and the observation group had notably higher QoL score than the control group (P < 0.05). The extent of glossectomy and nursing plan were independent risk factors impacting the recovery of swallowing function (P < 0.05). MDT nursing have a positive impact on oral hygiene as well as the swallowing function of patients after radical resection of TC, and MDT is a protective factor for swallowing function in the patients after radical resection.

Effects of Huoxue Qufeng Decoction combined with Tongguan Liquefying Acupoint Penetration therapy on swallowing function and quality of life in patients with ischemic stroke.

To analyze the effects of Huoxue Qufeng Decoction combined with Tongguan Liquefying Acupoint Penetration therapy on swallowing function and quality of life in patients with ischemic stroke. A total of 145 patients with post-stroke dysphagia admitted to Dingxi People's Hospital from January 2019 to May 2022 were selected with 65 patients in the control group and 80 patients in the observation group. The control group received Huoxue Qufeng Decoction alone, while the observation group received additional Tongguan Liquefying Acupoint Penetration therapy. Clinical efficacy, NIH Stroke Scale (NIHSS) score, Water Swallow Test, Swallowing Function Assessment (SSA) score, MD Anderson Dysphagia Inventory (MDADI) score, overall incidence of adverse events, and Swallowing Quality of Life (SWAL-QOL) score were compared between the two groups. The total response rate in the observation group was higher than that in the control group, with a statistically significant difference (P<0.01). After treatment, the SSA score and NIHSS score were statistically lower in the observation group than in the control group (P<0.01). The MDADI and SWAL-QOL scores were higher in the observation group than in the control group, with a statistically significant difference (both P<0.01). The total effective rate reflected by the Water Swallow Test was significantly higher in the observation group than in the control group (P<0.05). There was no significant difference in the incidence of adverse events between the two groups (P>0.05). Univariate analysis revealed that age and treatment plan were factors influencing the recovery of swallowing function. Logistic multivariate regression analysis further identified age and treatment plan as independent risk factors affecting patient prognosis (P<0.05). Huoxue Qufeng Decoction combined with Tongguan Liquefying Acupoint Penetration has a significant effect on post-stroke dysphagia, effectively improving swallowing function and enhancing quality of life.

Intervenções da Fonoaudiologia nas áreas de respiração, mastigação, deglutição e fala: uma revisão de escopo

ABSTRACT There are several types of approaches that can be used to achieve therapeutic goals in disorders related to the functions of mastication, swallowing, speech, and breathing. However, the literature lacks evidence to support their use in speech-language clinical practice. The objective of this review was to map the syntheses of evidence on speech-language pathology intervention in the areas of breathing, mastication, swallowing and speech in adults and the elderly. Only studies classified by their authors as a systematic review, studies that addressed therapy for orofacial disorders in individuals over 18 years of age were included. The procedures performed included: electronic and manual search; selection of studies; data extraction; evaluation of the quality of studies and data analysis. It was possible to observe different types of interventions mainly aimed at the swallowing function, ranging from traditional therapy to the use of devices. However, due to the limitations of the studies, the data must be interpreted with caution.

Adhesion Reduction Agent Guardix-SG® Versus MegaShield® for Postoperative Swallowing Function Analysis in Thyroidectomy Patients.

Antiadhesion products are essential for postoperative care in patients after thyroidectomy by providing a physical barrier to cover the exposed tissue and thus preventing abnormal adhesion of adjacent tissues. Since thyroidectomy may result in swallowing difficulties arising from damage or inflammation of the surrounding tissues, the use of antiadhesion agents such as MegaShield® or Guardix-SG® will help reduce scar formation. This may thus improve postoperative swallowing function in patients. Patients were enrolled and followed up between October 4, 2018, and March 26, 2020. Patients during the postoperative follow-up sessions were randomly allocated to the standard care with Guardix-SG® and clinical trial medical device application group with MegaShield® (test group) in a 1:1 ratio by the permuted block randomization method. Patient performance on penetration aspiration scale (PAS), National Institutes of Health-Swallow Safety Scale (NIH-SSS), videofluoroscopic dysphagia scale (VDS), Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) based on Videofluoroscopic swallowing study (VFSS) were collected. Nonadhesion-reducing agent patient data were used as a control group. No statistical significance was shown (P > .05) between the 2 groups of MegaShield® and Guardix-SG® in various phases from thick semisolid, thin semisolid to liquid for both PAS and NIH-SSS. Several statistical significances were reported in the results comparing various criteria of PAS, NIH-SSS, VDS at different oral and pharyngeal phases, and DIGEST in all 3 stages among MegaShield®, Guardix-SG®, and nonadhesion-reducing agent group. These results prove the noninferiority of MegaShield® compared with Guardix-SG® as an antiadhesion agent in postthyroidectomy care.

The influence of parenteral nutrition on the condition of the oral cavity: literature review.

Oral health plays a pivotal role in the overall well-being of patients. This article delves into the intricate interplay between oral health and systemic health outcomes in various patient populations, including those undergoing parenteral nutrition in childhood, individuals with impaired swallowing function, and those reliant on long-term enteral or parenteral nutrition. Through a comprehensive review of existing literature, the multifaceted role of oral health maintenance in optimizing nutritional therapy outcomes and enhancing overall quality of life is explored. Alternative forms of nutrition have a profound impact on Oral microbiota, which in turn is reflected in general health and wellbeing. Despite its significance, the importance of systematic oral health assessments and nurse involvement in providing holistic care to patients with complex medical needs has been underestimated. By elucidating critical connections between oral health and systemic health outcomes, this article aims to underscore the significance of oral health in comprehensive patient care and stimulate further research to advance our understanding of this crucial aspect of healthcare management.

Ab. No. 24 Role of Physical Rehabilitation Strategies Used in Dysphagia Management in Head and Neck Cancer Survivors- A Systematic Review

Introduction: Dysphagia is a common complication in head and neck cancer (HNC) patients who have undergone cancer treatment. Such patients have disrupted swallowing problems with decreased swallowing function even after 5 years post treatment. Rehabilitation strategies have been designed to enhance the mechanics of swallowing to achieve long lasting improvements. To quantitatively assess the previous research studies and to derive conclusion about various physical rehabilitation strategies focusing in decreasing dysphagia problems and improving Quality of Life (QOL) in Cancer survivors. Relevance: Systematic review shall help summarize existing research and contribute to informed, efficient, and reliable knowledge synthesis which will guide evidence-based decision-making in clinical practice, and research prioritization. Materials and Methods: Electronic search was conducted in Scopus, PubMed, PEDro, and COCHRANE databases. Studies that met the inclusion criteria were evaluated using PEDro scale and Modified McMaster Critical review form for quality appraisal. A descriptive synthesis was undertaken due to heterogeneity of the included studies. Analysis and Results: Total of 17 studies were assessed for Risk of Bias which comprised of 15 clinical trials, 1 Case Series, 1 Case Report that applied swallowing exercises, manoeuvres, Neuromuscular Electrical stimulation (NMES), to the HNC survivors. The outcomes highlighted improvement in swallowing, the oral intake status and QOL as assessed by various swallow/oral intake scales, radiographic examination and QOL scales. Conclusion: The review recommends application of swallowing exercises, manoeuvres, to HNC survivors however, authors speculate diminished use of NMES in such cases. It’s recommended that a well-designed larger sample size with randomization and double blinding would generate better evidence for combined utilization of NMES along with swallowing exercise for HNC survivors. Implications: This systematic review helps to know the lacunae in treatment and how we could strengthen the evidence.

Technology acceptance of the video game-based swallowing function training system among healthcare providers and dysphagia patients: A qualitative study.

Dysphagia is highly prevalent worldwide, causing serious complications. Video-game based rehabilitation training can increase dysphagia patient motivation and adherence. However, the acceptance of video game systems by patients and healthcare providers is still not fully explored. This study aimed to explore the acceptance of the video game swallowing training system among potential users. The in-depth interviews were conducted face-to-face between July and October 2023 at a rehabilitation center in China, with a sample size based on the principle of information saturation. Interviews were audio-recorded and transcribed verbatim, and the data were analyzed using theory-driven thematic analysis methods based on the technology acceptance model. A total of 19 participants participated in the interviews, which included 11 hospitalized dysphagia patients, three rehabilitation therapists, one doctor, and four nurses. Three themes and seven subthemes were identified. Sufficient training content, interesting interaction between the game and the rehabilitation training, intuitive page design, and efficient training modes were related to the usefulness of the system; user-friendly page design and simple interface could make it easier for participants to use the system. Overall, the availability of the video game system for use without geographical or time limitations led to a high level of participant intention to use the system, but it is still challenging to use it in the real world. The results of the study showed that participants were generally accepted and willing to use the video game system for dysphagia rehabilitation training. The video game-based swallowing function training system can be helpful in assisting with dysphagia rehabilitation.

Impact of low pharyngeal/esophageal pressure associated with sarcopenia on postendoscopic submucosal dissection pneumonia in patients with superficial esophageal cancer.

The aging population, including patients with superficial esophageal cancer, encounters critical dysphagia- and postoperative pneumonia-related issues. Although endoscopic submucosal dissection (ESD) provides advantages over other modalities, older patients are at higher risk of postoperative pneumonia. Furthermore, the etiologies of pneumonia are complex and include patient- (such as sarcopenia) and treatment- (including ESD) related factors. Therefore, this study evaluated swallowing function in patients with superficial esophageal cancer and identified post-ESD pneumonia-associated factors. Comprehensive swallowing function and sarcopenia were evaluated in patients pre-ESD and 2 months post-ESD using high-resolution manometry and several swallowing studies by multiple experts. The effects of mucosal resection and sarcopenia on swallowing function changes post-ESD, the relationship between preoperative swallowing function and sarcopenia, and the factors influencing postoperative pneumonia were investigated. Twenty patients were included in the study. Patients with preoperative sarcopenia had significantly lower pharyngeal/upper esophageal sphincter and tongue pressures than those without sarcopenia. However, ESD did not worsen pharyngeal or upper esophageal pressure. Post-ESD pneumonia incidence tended to be higher in patients with sarcopenia than in those without sarcopenia. The lower upper esophageal sphincter-integrated relaxation pressure (UES-IRP) was a significant factor in pneumonia development. Furthermore, the receiver operating characteristic curve for UES-IRP in pneumonia yielded an area under the curve of 0.82. Sarcopenia is associated with preoperative dysphagia, which increases post-ESD pneumonia risk. Therefore, postoperative pneumonia incidence is expected to increase with an aging population, making preoperative sarcopenia and swallowing function evaluation crucial.

Implementing flexible endoscopic evaluation of swallow screening within annual cancer surveillance appointments to monitor for late-stage radiation-induced dysphagia: A feasibility study.

Late-stage progressive decline of swallowing function after radiotherapy for head and neck cancer (HNC) is often difficult to monitor. This study examined the feasibility and clinical outcomes of speech-language pathology implementing flexible endoscopic evaluation of swallow (FEES) screening during annual cancer surveillance visits to monitor late-stage swallowing function. Patients >2 years post treatment who attended routine oncological visits underwent FEES screening. Feasibility (service data, stakeholder survey) and swallowing outcomes (oral intake, secretions, internal lymphedema, penetration-aspiration, and residue) were collected. Screening was completed with 70% (50/71) of eligible patients. Medical staff and speech-language pathologists indicated the protocol was worthwhile and achievable to incorporate into practice. Almost all patients were willing to complete the protocol annually. FEES outcomes identified 84% with dysphagia versus only 26% self-reported dysphagia. Findings indicate FEES screening incorporated into annual oncological reviews is feasible and effective at monitoring late-stage swallowing function following HNC.

Impact of sarcopenia and malnutrition on swallowing function utilizing ultrasonography in patients with acute heart failure: A retrospective cohort study

This study aimed to determine the impact of sarcopenia and nutritional risk on swallowing-related muscles by ultrasonography and dysphagia occurrence in older patients with acute heart failure (AHF) during hospitalization. Patients with AHF aged ≥65 years without dysphagia (Food Intake LEVEL Scale [FILS] score ≥9) before admission were classified into four groups at admission: robust group, sarcopenia group (Asian Working Group for Sarcopenia 2019), nutritional risk group (geriatric nutritional risk index <92), and complicated group (with both sarcopenia and nutritional risk). Swallowing function (maximal hyoid displacement, geniohyoid muscle area and brightness, and maximal tongue pressure) and FILS were investigated from the medical records. In total, 131 patients with AHF (mean age 82.8±7.1 years, 71 males) were enrolled during the study period; 33, 58, 5, and 35 were classified into the robust, sarcopenia, nutritional risk, and complicated groups, respectively. In the covariance analysis adjusted for age, sex, comorbidities, and cardiac function, the complicated group had significantly worse swallowing function than the sarcopenia and robust groups (P<0.05). In the Cox proportional hazards model, in which event occurrence was defined as the first-time FILS score of ≥9 obtained during hospitalization, the sarcopenia group (hazard ratio [HR]: 0.83, 95% confidence interval [CI]: 0.51-1.34, P=0.438) and nutritional risk group (HR: 0.77, 95% CI:0.25-2.32, P=0.637) were not significantly different, but the complicated group (HR: 0.54, 95% CI: 0.31-0.95, P=0.033) had significantly lower cumulative event rates with the robust group as the reference. Sarcopenia and nutritional risk in older patients with AHF are risk factors for decreased swallowing function.

Pharyngeal Cavity Electrical Stimulation-Assisted Swallowing for Post-stroke Dysphagia: A Systematic Review and Meta-analysis of Randomized Controlled Studies.

Stroke is the leading cause of death and disability among adults. The incidence of stroke per 100, 000 patient-years was 2875. As many as 37% to 78% of patients with acute strokes suffer dysphagia. Dysphagia can easily lead to inhalation pneumonia, dehydration, malnutrition, and other serious complications, affecting the quality of life of stroke patients and increasing their mortality. Effective prevention and treatment of post-stroke dysphagia are of great significance to improving the prognosis and quality of life of patients. Some studies have shown that Pharyngeal cavity electrical stimulation-assisted swallowing (PCES-assisted swallowing) has a positive effect on patients with post-stroke dysphagia. This study will evaluate the effects of PCES-assisted swallowing on post-stroke dysphagia, including swallowing function, withdrawal rate of nasal feeding tubes, duration of hospitalization, and so on. Randomized controlled trials (RCTs) of PCES-assisted swallowing in the treatment of post-stroke dysphagia were searched in eight databases, including Cochrane Library, Embase, PubMed, Web of Science, Chinese Biomedical Literature Database, VIP Information Resource System, CNKI, and Wanfang Medical Science. The retrieval time was from the database establishment to June 2022. Rayyan was used to screen the retrieved literature risk of bias for included studies and was calculated using ROB2.0. The RevMan 5.3 software was used for the meta-analysis with the standard mean difference (SMD) and 95% confidence interval (CI). The model type was a random effect model, The risk ratio (RR) was used as the effect size for the two categorical variables. The swallowing function scores, withdrawal rate of nasal feeding tubes, and Length of stay (LOS) of the intervention and control groups were extracted, and the results of the meta-analysis were presented using a forest plot. Six studies from 2010 to 2018 with a total of 341 people were included in the meta-analysis. All studies reported quantitative outcome measures for the severity of dysphagia, and some reported the withdrawal rate of nasal feeding tubes, LOS, and penetration-aspiration-scale (PAS). The overall swallowing function of the PCES group was better than that of the control group (SMD = -0.20, 95%CI -0.38 to -0.03, P = 0.02). In terms of the severity of dysphagia, there was a statistically significant difference in the Dysphagia Severity Rating scale (DSRS) between the Pharyngeal cavity electrical stimulation (PCES) group and the control group (SMD = -0.24, 95%CI -0.48 to 0, P = 0.05). The PCES group nasal feeding withdrawal rate of nasal feeding tubes was higher than the control group (RR = 2.88, 95% CI 1.15 to 7.26, P = 0.02). There was no significant difference in the LOS between the PCES group and the control group (SMD = -0.19, 95%CI -0.44 to 0.07, P = 0.15). This systematic review and meta-analysis provide reasonably reliable evidence that PCES-assisted swallowing can improve nasogastric feeding swallowing function and the withdrawal rate of nasal feeding tubes in patients with post-stroke dysphagia. However, the evidence for reducing oral feeding, aspiration, and length of hospitalization stay is lacking, and further studies are needed.

ENHANCING ORTHODONTIC TREATMENT FOR PATIENTS WITH SWALLOWING AND SPEECH DISORDERS

Introduction. At the modern level, disorders of the functions of the tongue are considered by scientists in close relationship with the condition of the cranio-mandibular structures, posturological changes and various general somatic disorders of the human body.&#x0D; The purpose of this study was to improve the effectiveness of orthodontic treatment outcomes for patients with disorders of tongue functions based on data obtained from the systematic review of revelant literature and own clinical experience.&#x0D; Materials and Methods. The research involved an analysis of contemporary national and international literature spanning from 2000 to the present. Additionally, the study summarized the clinical experience gained from examining and treating 1024 patients with swallowing and speech disorders over the past 8 years.&#x0D; Results. The "Algorithm for investigating the state and position of the tongue during swallowing and speech functions" has been formulated. This algorithm encompasses stages of clinical and paraclinical analysis, evaluating factors such as the tongue position, the condition of supra- and sublingual spaces, pharyngeal airways, hyoid bone position, as well as using techniques such as photopalatography, electropalatography, and electromyography. The corrective method we offer for addressing improper tongue positioning during swallowing and speech involves enhancing the patient's overall somatic condition through recommendations for a healthy diet, an active lifestyle, and specific myogymnastics. It further focuses on normalizing the myodynamic balance between the external and internal muscle circles of the dento-jaw area. Controlled myogymnastics for the tongue is facilitated using a specially designed device.&#x0D; Conclusion. The developed algorithm for studying the condition and position of the tongue during swallowing and speech functions, along with the proposed corrective method, promises to enhance the effectiveness of diagnosing malocclusion associated with or caused by tongue function disorders. This approach contributes to the objectification of results in orthodontic treatment.

Relationship between the jaw-closing force and dietary form in older adults without occlusal support requiring nursing care

In clinical practice, we encounter cases wherein older adults lacking occlusal support consume foods requiring mastication and adequate swallowing function. This study investigated the relationship between jaw-closing force (JCF) and dietary form in older adults without occlusal support requiring nursing care. This prospective cross-sectional study included 123 older adults requiring nursing care who lost their molar occlusal support and consumed food orally without dentures. JCF was defined as the force required for crushing food with the edentulous ridges or with the tooth and edentulous ridge while closing the mouth. Participants were classified into four groups based on the International Dysphagia Diet Standardization Initiative framework for recommended dietary forms. Basic information was collected, and tongue pressure and JCF were measured. Differences in JCF were analyzed using one-way analysis of variance, while factors related to dietary form were evaluated using ordinal logistic regression analysis. Significant differences in JCF were observed among the four groups. Factors such as the Barthel Index, tongue pressure, and JCF were dietary form-related. Our findings suggest that older adults requiring nursing care tend to have higher JCF when consuming meals requiring mastication. Therefore, JCF could serve as an index for determining appropriate dietary forms in this population.
