Affecting over 50% of stroke patients, dysphagia is still challenging to diagnose and manage due to its complex multifactorial nature and can be the result of disruptions in the coordination of cortical and subcortical neural activity as reflected in electroencephalographic (EEG) signal patterns. Sample Entropy (SampEn), a signal complexity or predictability measure, could serve as a tool to identify any abnormalities associated with dysphagia. The present study aimed to identify quantitative dysphagia biomarkers using SampEn from EEG recordings in post-stroke patients. Sample entropy was calculated in the theta, alpha, and beta bands of EEG recordings in a repetitive swallowing task performed by three groups: 22 stroke patients without dysphagia (controls), 36 stroke patients with dysphagia, and 21 healthy age-matched individuals. Post-stroke patients, both with and without dysphagia, exhibited significant differences in SampEn compared to healthy subjects in the alpha and theta bands, suggesting widespread alterations in brain dynamics. These changes likely reflect impairments in sensorimotor integration and cognitive control mechanisms essential for effective swallowing. A significant cluster was identified in the left parietal region during swallowing in the beta band, where dysphagic patients showed higher entropy compared to healthy individuals and controls. This finding suggests altered neural dynamics in a region crucial for sensorimotor integration, potentially reflecting disrupted cortical coordination associated with dysphagia. The precise quantification of these neurophysiological alterations offers a robust and objective biomarker for diagnosing neurogenic dysphagia and monitoring therapeutic interventions by means of EEG, a non-invasive and cost-efficient technique.

Background/Objectives: Infants admitted to neonatal intensive care units (NICUs) face challenges in achieving successful oral feedings. During oral feedings, these infants commonly present with suck–swallow–breathe incoordination, with approximately 30% developing dysphagia, leading to feeding aversion, prolonged hospitalization, and increased parental stress. Cold liquid feeding has demonstrated benefits in improving feeding safety in adults with dysphagia; however, its application in neonates is relatively limited. This study aimed to examine global neonatal feeding practices, with a specific emphasis on cold milk feeding as an intervention for dysphagia. Methods: A cross-sectional global electronic survey was distributed via professional society listservs and closed online professional group forums targeting neonatal providers and feeding therapists from June 2023 to June 2024. The survey assessed institutional feeding protocols, oral feeding practices, and the use of cold milk for infants with dysphagia. Responses were analyzed descriptively. Results: A total of 210 complete responses were received from level IV (51%), level III (42%), and level II (5%) NICUs. While 30% of the respondents were aware of cold milk feeding as a dysphagia intervention, only 15% of the total respondents reported using it in practice. Among the 32 institutions implementing cold milk practices, only one had an established protocol. Additionally, 72% reported having a feeding protocol in place, often incorporating cue-based tools. Most respondents (87.5%) did not allow oral feeding during nasal continuous positive airway pressure (nCPAP), whereas 78% permitted it during high-flow nasal cannula (HFNC) support. Conclusions: Although the awareness of cold milk feeding in neonates is increasing, its implementation remains limited and lacks standardization. Significant variability exists in oral feeding practices, particularly regarding feeding during respiratory support. This underscores the need for further research and evidence-based guidelines to ensure safe and consistent care for preterm infants. Full article

(1) Background: Biofeedback and neurofeedback are gaining attention as non-invasive rehabilitation strategies in Parkinson’s disease (PD) treatment, aiming to modulate motor and non-motor symptoms through the self-regulation of physiological signals. (2) Objective: This review explores the application of biofeedback techniques, electromyographic (EMG) biofeedback, heart rate variability (HRV) biofeedback, and electroencephalographic (EEG) neurofeedback in PD rehabilitation, analyzing their impacts on motor control, autonomic function, and cognitive performance. (3) Methods: This review critically examined 15 studies investigating the efficacy of electromyographic (EMG), heart rate variability (HRV), and electroencephalographic (EEG) feedback interventions in PD. Studies were selected through a systematic search of peer-reviewed literature and analyzed in terms of design, sample characteristics, feedback modality, outcomes, and clinical feasibility. (4) Results: EMG biofeedback demonstrated improvements in muscle activation, gait, postural stability, and dysphagia management. HRV biofeedback showed positive effects on autonomic regulation, emotional control, and cardiovascular stability. EEG neurofeedback targeted abnormal cortical oscillations, such as beta-band overactivity and reduced frontal theta, and was associated with improvements in motor initiation, executive functioning, and cognitive flexibility. However, the reviewed studies were heterogeneous in design and outcome measures, limiting generalizability. Subgroup trends suggested modality-specific benefits across motor, autonomic, and cognitive domains. (5) Conclusions: While EMG and HRV systems are more accessible for clinical or home-based use, EEG neurofeedback remains technically demanding. Standardization of protocols and further randomized controlled trials are needed. Future directions include AI-driven personalization, wearable technologies, and multimodal integration to enhance accessibility and long-term adherence. Biofeedback presents a promising adjunct to conventional PD therapies, supporting personalized, patient-centered rehabilitation models. Full article

Background: Quality of life (QoL) is a critical indicator in assessing the success of oncological treatments for head and neck malignancies, reflecting their impact on physiological functions and psychosocial well-being beyond mere survival. Treatments (surgery, radiotherapy, chemotherapy) pose multiple functional and emotional challenges, and recent advancements underscore the necessity of evaluating post-treatment QoL. Objective: This literature review investigates the impact of oncological treatment on the QoL of patients with malignant head and neck cancers (oral, oropharyngeal, hypopharyngeal, laryngeal) and identifies factors influencing their QoL index. Methodology: Using a PICO framework, studies from PubMed Central were analyzed, selected based on inclusion (English publications, full text, PROM results) and exclusion criteria. The last research was conducted on 6 April 2025. From 231 identified studies, 49 were included after applying filters (MeSH: “Quality of Life,” “laryngeal cancer,” “oral cavity cancer,” etc.). Data were organized in Excel, and the methodology adhered to PRISMA standards. Results: Treatment Impact: Oncological treatments significantly affect QoL, with acute post-treatment declines in functions such as speech, swallowing, and emotional well-being (anxiety, depression). Partial recovery depends on rehabilitative interventions. Influencing Factors: Treatment type, disease stage, socioeconomic, and demographic contexts influence QoL. De-escalated treatments and prompt rehabilitation improve recovery, while complications like trismus, dysphagia, or persistent hearing issues reduce long-term QoL. Assessment Tools: Standardized PROM questionnaires (EORTC QLQ-C30, QLQ-H&N35, MDADI, HADS) highlighted QoL variations. Studies from Europe, North America, and Asia indicate regional differences in outcomes. Limitations: Retrospective designs, small sample sizes, and PROM variability limit generalizability. Multicentric studies with extended follow-up are recommended. Conclusions: Oncological treatments for head and neck malignancies have a complex impact on QoL, necessitating personalized and multidisciplinary strategies. De-escalated therapies, early rehabilitation, and continuous monitoring are essential for optimizing functional and psychosocial outcomes. Methodological gaps highlight the need for standardized research. Full article

Objectives: The present study examined cross-sectional and longitudinal associations between dysphagia and a variety of health-related parameters, including physical performance, cognitive function, malnutrition, sarcopenia, disability, frailty, falls, hospitalization, and mortality in a cohort of octogenarians living in the mountainous Sirente region of Central Italy. Methods: Dysphagia was operationalized as the need to modify the diet to facilitate swallowing and/or the exclusive consumption of specific food consistencies due to swallowing difficulties. Physical performance, cognitive function, malnutrition, disability, falls, and hospitalizations were assessed via the Minimum Data Set for Home Care. Sarcopenia was defined as the coexistence of low muscle mass and dynapenia, while frailty was operationalized according to Fried’s phenotype. History of falls and incident falls, as well as disability, were tracked over two years, while survival status was followed for up to ten years. Results: Data of 362 older adults (men age: 85.9 ± 4.8; body mass index: 25.6 ± 4.53; women: 66.9%; multimorbidity: 21.5%; dysphagia: 6.6%) were analyzed. The results indicated that dysphagia was significantly and cross-sectionally associated with poor physical performance and reduced cognitive function. In contrast, no longitudinal associations were observed. Conclusions: Dysphagia appears to be linked to deficits in physical and cognitive domains, underscoring the value of comprehensive geriatric assessment and the development of multidomain intervention strategies.

Dysphagia is a serious complication following cardiac surgery, associated with increased morbidity, prolonged hospitalization, and higher healthcare costs. Variability in the incidence and risk factors highlights the need for consolidated evidence. This scoping review aimed to analyze the incidence of dysphagia after cardiac surgery and identify the associated risk factors. A search was conducted in the PubMed, Embase, Web of Sciences, and PEDro databases for observational studies reporting dysphagia incidence and risk factors in adult cardiac surgery patients. The Newcastle–Ottawa Scale was used to assess the studies’ quality and out of 2920 studies identified, 15 met the inclusion criteria for inclusion in this review. Dysphagia incidence ranged from 2.7% to 60%, with higher rates observed when objective assessments such as FEES or VFSS were employed. Key risk factors included advanced age, prolonged intubation, cerebrovascular events, and complex operative procedures. Post-operative dysphagia was linked to complications like aspiration pneumonia, prolonged ICU/hospital stays, and increased healthcare costs. In conclusion, dysphagia is a significant but under-recognized complication of cardiac surgery. Advanced age, prolonged intubation, and surgical complexity are major risk factors. Standardized assessment protocols and early interventions are crucial to mitigating its impact and improving patient clinical outcomes. Full article

Background: Children with Down syndrome (DS) are at high risk for a broad spectrum of otorhinolaryngologic (ENT) disorders, including hearing impairment, obstructive sleep apnea (OSA), dysphagia, and language delay. These conditions often coexist and interact with the neurodevelopmental and anatomical features of DS, requiring early identification and coordinated management. Despite the clinical burden, ENT involvement in DS remains under-characterized and inconsistently addressed in care pathways. Methods: A narrative review was conducted to provide an integrative overview of ENT manifestations in pediatric patients with DS. A literature search was performed in PubMed, Scopus, and Web of Science, covering studies published between 1979 and 2025. Articles were included if they addressed ENT disorders in children with DS and met clinical relevance criteria. A total of 45 studies were selected and analysed by study design, focus, and contribution to diagnostic or therapeutic frameworks. Results: The majority of included studies were observational in nature, covering key domains such as conductive hearing loss, chronic otitis media with effusion, sleep-disordered breathing, and feeding/swallowing dysfunction. Several articles emphasized the importance of early audiologic and polysomnographic screening. Gaps in standardization and accessibility of multidisciplinary ENT care were consistently reported. A proposed framework for integrated evaluation is discussed. Conclusions: ENT manifestations in pediatric DS are frequent, multifactorial, and clinically impactful. A multidisciplinary, anticipatory model of care is essential for timely diagnosis and targeted intervention. This review highlights the need to formalize ENT pathways within comprehensive care protocols for children with DS. Full article

Eosinophilic esophagitis (EoE) is a chronic, immune-mediated disease characterized by esophageal eosinophilic infiltration, leading to symptoms such as dysphagia and food impaction. Endoscopy is central to both diagnosis and management, allowing for the direct visualization of characteristic features, biopsy collection, and therapeutic interventions. Despite its diagnostic value, up to one-third of patients may present with a normal-appearing esophagus, highlighting the importance of standardized scoring systems and a systematic biopsy approach. This review explores the evolving role of endoscopy in EoE, from traditional diagnostic methods to emerging technologies such as EndoFlip™ for assessing esophageal distensibility, transnasal endoscopy for non-sedated monitoring, and novel dilation techniques for fibrostenotic disease. Additionally, non-invasive biomarkers and minimally invasive tools are reshaping disease monitoring. By integrating endoscopic, histologic, and molecular approaches, future advancements may enhance diagnostic accuracy and optimize personalized treatment strategies for EoE. Full article

Background: Pharyngeal stenosis (PS) is a common sequela of a total laryngectomy (TL), and the most common cause of postoperative dysphagia. Its exact incidence is not known. A greater understanding of this clinical complication could serve to better inform patients considering a laryngectomy. Objective: Pharyngeal stenosis (PS) is a common sequela of a total laryngectomy (TL) and causes dysphagia. This systematic review aims to characterize PS as a sequela of a TL, specifically the incidence of dysphagia requiring dilation, and the frequency/timing of dilation interventions. Data Sources: We used PubMed. Review Methods: A search of all studies from PubMed published from conception to January 2024 was conducted. Cohort studies reporting PS requiring dilation following a TL were included. Data were collected on the incidence, recurrence, median time from TL to dilation, TL indication, and reconstructive approach. Two evaluators independently performed the study screening and data collection; all the differences were resolved by a third evaluator. Results: Eleven studies met the inclusion criteria. A total of 1421 patients underwent a TL, of which 659 (46.4%) were salvage, 286 (20.1%) were the primary treatment, and 153 (10.8%) were the primary with an adjuvant treatment. A total of 255 patients underwent reconstruction, among whom 86 (33.7%) had regional and 169 (66.3%) had free flaps. The mean age at the time of the TL was 64.1 (range 20–87) years, with a male-to-female ratio of 3.4:1. The overall incidence of dysphagia after a TL requiring dilation was 26%. Of the 370 patients who required dilation, 69.4% required multiple procedures. The median time to the first dilation post-TL ranged from 9 to 24 months. The overall complication rate was 4.3%, including perforation, infection, and diminished tracheoesophageal voice quality. Conclusions: Approximately one in four patients developed stenosis requiring dilation after a TL, of which two out of three required repeat dilations. Major complications, though rare, were predominantly observed during the first few dilation procedures. Full article

Background/Objectives: Oropharyngeal dysphagia (OD) is a prevalent symptom in patients with neuromuscular diseases (NMDs) and increases the risk of aspiration and malnutrition. Malnutrition is frequent in these patients and is not only related to dysphagia, but also generates a vicious circle that may result in worsening muscle atrophy and weakness. Texture modification is required to ensure safe and efficient swallowing. This study evaluates the acceptability of a ready-to-mix oral nutritional supplement (ONS) containing high-quality protein and a xanthan-based thickener in patients with OD and NMDs. Methods: This cross-sectional study includes adult patients with NMDs and OD who received a xanthan gum-based protein ONS. Patients completed a questionnaire to rate their satisfaction with the ONS. Results: Seventy-two patients were included (median age = 56 years; 51% were males). The percentage of patients with moderate-to-severe OD who rated the taste, consistency, and product quality as acceptable-to-very-satisfactory (score 3–5) were 76%, 80%, and 84%, respectively. After three months, 93% of patients continued consuming the ONS. Conclusions: Our findings support that the use of protein xanthan gum-based ONS can be as a palatable and an effective nutritional intervention, given their high satisfaction and acceptance rates among patients with NMDs and OD.

The human papillomavirus type 16 (HPV 16) is a high-risk human papillomavirus strain commonly associated with oropharyngeal cancers, including lymph node involvement. The treatment for HPV 16-related tonsil cancer, commonly involving surgery, radiation, and chemotherapy, presents significant challenges. Complications such as oral mucositis, xerostomia, dysphagia, dysgeusia, hypogeusia, impaired gustatory function, and significant weight loss frequently arise, leading to reduced nutritional intake, impaired healing, and recovery progression. These challenges underscore the need for supportive interventions to enhance rehabilitation and the post-recovery period, improve treatment tolerance, and maintain quality of life. Objective: This single-subject study examines a 67-year-old male patient diagnosed with a T1N3b (small primary tumor with advanced lump node involvement) associated with HPV 16 positivity, indicating a virus-associated oncogenesis. Methods: The patient underwent radiation therapy and chemotherapy, leading to treatment-associated side effects. After having dietary drinks for daily nourishment, the patient routinely incorporated oral bio extra virgin olive oil (BEVOO) to cope with indicated challenges. Results: Body composition and metabolic parameters showed treatment-induced declines, followed by substantial but not complete recovery during follow-up examination. Visual Analog Scale (VAS) scores reflected gradual improvements in dysphagia, xerostomia, mucositis, and subtle but ongoing enhancement of the dysgeusia, gustatory perception, and oral palatability. The BEVOO supplementation and mindfulness were associated with positive recovery trends. Additional variables could have impacted the outcomes, preceding and throughout treatment, including the patient’s cognitive and somatic health, environmental conditions, dietary habits, individual attitudes toward recovery, physical activity, and patient way of life. Conclusions: These results emphasize the need for additional research employing a comprehensive, multi-factorial framework that accounts for the complex interplay of physiological, psycho-social, and environmental contributors. More extensive, more diverse studies are essential to confirm these observations and substantiate the role of BEVOO as a supportive intervention in cancer recovery. Full article

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder characterized by the progressive degeneration of upper and lower motor neurons, leading to muscle atrophy, paralysis, and respiratory failure. This comprehensive review synthesizes the current knowledge on ALS pathophysiology, clinical heterogeneity, diagnostic frameworks, and evolving therapeutic strategies. Mechanistically, ALS arises from complex interactions between genetic mutations (e.g., in C9orf72, SOD1, TARDBP (TDP-43), and FUS) and dysregulated cellular pathways, including impaired RNA metabolism, protein misfolding, nucleocytoplasmic transport defects, and prion-like propagation of toxic aggregates. Phenotypic heterogeneity, manifesting as bulbar-, spinal-, or respiratory-onset variants, complicates its early diagnosis, which thus necessitates the rigorous application of the revised El Escorial criteria and emerging biomarkers such as neurofilament light chain. Clinically, ALS intersects with frontotemporal dementia (FTD) in up to 50% of the cases, driven by shared TDP-43 pathology and C9orf72 hexanucleotide expansions. Epidemiological studies have revealed a lifetime risk of 1:350, with male predominance (1.5:1) and peak onset between 50 and 70 years. Disease progression varies widely, with a median survival of 2–4 years post-diagnosis, underscoring the urgency for early intervention. Approved therapies, including riluzole (glutamate modulation), edaravone (antioxidant), and tofersen (antisense oligonucleotide), offer modest survival benefits, while dextromethorphan/quinidine alleviates the pseudobulbar affect. Non-pharmacological treatment advances, such as non-invasive ventilation (NIV), prolong survival by 13 months and improve quality of life, particularly in bulb-involved patients. Multidisciplinary care—integrating physical therapy, respiratory support, nutritional management, and cognitive assessments—is critical to addressing motor and non-motor symptoms (e.g., dysphagia, spasticity, sleep disturbances). Emerging therapies show promise in preclinical models. However, challenges persist in translating genetic insights into universally effective treatments. Ethical considerations, including euthanasia and end-of-life decision-making, further highlight the need for patient-centered communication and palliative strategies. Full article

Background/Objectives: Pontine cavernomas are rare and challenging vascular malformations, representing a critical subset of brainstem lesions due to their deep location and proximity to essential neural structures. When hemorrhagic, these lesions can cause rapid neurological deterioration, posing life-threatening risks. Management requires a delicate balance between aggressive intervention and preserving vital functions. This case report presents the successful surgical treatment of a giant hemorrhagic pontine cavernoma, highlighting the integration of advanced imaging, precision surgical techniques, and multidisciplinary care to achieve an exceptional patient outcome. Methods: A 47-year-old female presented with acute neurological deterioration, including severe right-sided hemiparesis, dysphagia, and obnubilation. High-resolution MRI, including susceptibility-weighted imaging, confirmed a giant hemorrhagic pontine cavernoma causing brainstem compression. An urgent left-sided pterional craniotomy with a transsylvian approach was performed to access the lesion. Subtotal resection and hematoma evacuation were carried out to relieve brainstem compression while preserving critical structures. Postoperative recovery and lesion stability were evaluated through clinical assessments and imaging after three months. Results: Postoperatively, the patient exhibited marked neurological recovery, with near-complete resolution of hemiparesis, restored swallowing function, and significant functional improvement. Follow-up imaging confirmed a stable residual lesion, no recurrence of hemorrhage, and a well-preserved ventricular system. The combination of early intervention and tailored surgical strategies resulted in a highly favorable outcome. Conclusions: This case underscores the complexity of managing giant hemorrhagic pontine cavernomas and demonstrates that carefully planned surgical intervention, combined with advanced imaging and patient-focused care, can yield remarkable outcomes. It highlights the critical importance of early diagnosis, meticulous surgical planning, and future innovations in neurovascular surgery to improve outcomes in these rare but high-stakes cases.

Background: Over the last two decades, therapy for benign esophageal strictures has shifted from empirical dilatations and surgery to evidence-based and complex endoscopic and surgical procedures, aiming to achieve long-term esophageal patency. Aim: The purpose of our study is to provide descriptive evidence regarding the appropriate tailored medical, endoscopic, and surgical management of benign esophageal strictures. Methods: This retrospective study includes patients with benign esophageal strictures; the data collected encompass the complete patient profiles, detailed etiologic and anatomic workups of the strictures, comprehensive imaging, as well as management and follow-up details. Technical and clinical success rates, adverse events, stricture patency, and the need for additional therapy have been evaluated. Results: Most of the strictures (80.2%) were complex, requiring advanced techniques for management. The primary treatment involved endoscopic dilation, performed with Savary-Gillard bougie dilators in 76.7% of cases and pneumatic balloon dilators in 23.3% of cases. Clinical success was achieved in 95.3% of patients, with a significant improvement in the Ogilvie dysphagia score. Patients with caustic strictures required repeated dilations over the years, compared to shorter intervals for peptic strictures. Adverse events were minimal (e.g., perforation 2.3% and bleeding 4.7%) and managed predominantly endoscopically. Refractory strictures (16.3%) required advanced interventions, including fully covered self-expandable metallic stents (fc-SEMS) and corticosteroid injections. Conclusions: Both our data and the current literature support the use of tailored endoscopic strategies as the first-choice options for managing benign esophageal strictures. Our results strongly suggest against one-size-fits-all therapeutic alternatives. Full article

Background: This pilot investigation aimed to evaluate the efficacy of Global Intensive Feeding Therapy (GIFT) on feeding and swallowing abilities in children with CHARGE Syndrome (CS). GIFT is a novel rehabilitation program designed to leverage the principles of neuroplasticity, intensity, individualized treatment, and ecological validity. The program comprises 15 sessions conducted over one week, with sessions delivered three times per day. Methods: GIFT was preliminarily implemented in a cohort of seven children diagnosed with CS. To assess the risk of dysphagia, the Pediatric Screening–Priority Evaluation Dysphagia (PS-PED) was administered. The effectiveness of the intervention was evaluated using three instruments: the Karaduman Chewing Performance Scale (KCPS) for chewing performance, the American Speech-Language-Hearing Association National Outcome Measurement System (ASHA NOMS) for overall feeding abilities, and the Feeding Assessment Scale (FAS) to capture parents’ perceptions. Data were collected at baseline (T0), immediately post-intervention (T1), and at a six-month follow-up (T2). The Wilcoxon signed-rank test was employed for statistical analysis, and effect sizes for specific outcomes were determined using Kendall’s W. Results: The findings indicated that children with CS were at a high risk of dysphagia as measured by the PS-PED at baseline. Statistically significant improvements in chewing performance were observed at the six-month follow-up (p < 0.05). Feeding abilities, as measured by the ASHA NOMS, showed significant enhancement immediately post-intervention (p = 0.02) and at the follow-up (p = 0.03). Similarly, parents reported significant improvements in their children’s feeding abilities at both post-intervention and follow-up assessments (p = 0.02), further corroborating the clinical benefits of the intervention. Conclusions: These preliminary results suggest that GIFT may be an effective rehabilitation program for addressing feeding and swallowing disorders in children with CS. Further studies with larger sample sizes and controlled designs are warranted to substantiate these findings and refine the intervention protocol. Full article
