Summary: This study aimed to assess the relationship between tongue pressure and swallowing function, and found that dysphagia patients with sarcopenia have weaker pharyngeal contractility and UES dysfunction. However, there was no significant correlation between HRM parameters and tongue pressure as well as sarcopenia-related factors. Further research is needed to clinically apply tongue pressure in evaluating sarcopenic dysphagia.

Summary: This study evaluated the diagnostic yield of high-resolution manometry in Thai patients, finding the highest yield in dysphagia patients. However, the test was not as beneficial in detecting clinically relevant esophageal motor disorders in patients presenting with non-dysphagia symptoms.

Summary: This study examined the effect of topical nasal anesthetic (TNA) on swallowing and tolerability during high-resolution impedance manometry (HRIM) with a 4.2-mm catheter. The results showed that TNA did not improve comfort or significantly affect swallowing behavior during the procedure.

Summary: The study aimed to investigate the effects of bolus volume and viscosity on pharyngeal swallow using circumferential pressure sensor technology and found that larger volumes increased intrabolus pressure and all upper esophageal sphincter metrics, while thicker viscosity decreased UES relaxation time and flow timing metrics. The use of this technology provides consistent results with previous reports, offering insights into aberrant pharyngo-esophageal motor responses over time.

Summary: There is a growing interest in developing inexpensive and portable methods for accurately assessing swallowing during dysphagia treatment. High-resolution cervical auscultation (HRCA) is a novel method using acoustic and vibratory signals from non-invasive sensors to quantify swallowing physiology. The study found that HRCA can accurately differentiate between non-effortful and effortful swallows, but there were no differences in Modified Barium Swallow Impairment Profile (MBSImP) scores between the two types of swallows.

Summary: This study investigated the effect of different body positions on esophageal motility using high-resolution manometry. Results showed stronger esophageal contractions in the bridge position compared to upright, with shorter peristaltic breaks and longer distal latency. Further research is needed to examine the effectiveness of swallowing in the bridge position.

Summary: Establishing reference values for temporal kinematic swallow events in healthy adults and annotating these events using HRCA showed some measurements aligned with previous studies, but others differed, highlighting the need for further standardization. Machine learning algorithms using HRCA signal features demonstrated promising accuracy in annotating key swallow events, suggesting potential for noninvasive dysphagia screening cutoffs.

Summary: This study investigated the operation of VFS clinics in the UK and found limited translation of VFS guidelines into practice, which may impact the quality of assessment and analysis. Collaboration with radiology, strengthening of guidelines, and greater uptake of specialist training are deemed essential.

Summary: The study found that patients prefer atomized lidocaine for increased comfort during pharyngeal high-resolution manometry procedures. While no significant differences were detected in pharyngeal pressure measurements between the two groups, the use of atomized lidocaine did not affect measurement outcomes.

Summary: This study aimed to investigate the clinical characteristics of patients with possible and probable sarcopenic dysphagia, categorizing patients based on tongue pressure into probable and possible groups. The results showed that patients with probable sarcopenic dysphagia exhibited poorer swallowing ability and activities of daily living compared to those with possible sarcopenic dysphagia.

Summary: This study compared two methods of measuring upper esophageal sphincter (UES) relaxation and determined their diagnostic value in UES relaxation impairment. The results showed that VFSS and HRM have complementary ability in evaluating UES relaxation duration in patients with oropharyngeal dysphagia.

Summary: Pharyngeal tongue base augmentation therapy can improve dysphagia post head and neck cancer treatment by increasing pharyngeal pressures during swallowing, resulting in improved swallow symptoms.

Summary: This study investigated and described the clinical practice patterns related to videofluoroscopic swallowing studies (VFSS) assessments among Speech-Language Pathologists (SLPs) in India. The findings showed variability in the responses of the participants and a lack of radiation safety measures. The results suggest a need for increased awareness and training among Indian SLPs in the technical and procedural aspects of VFSS, as well as more emphasis on radiation safety. The establishment of uniform nationwide practices in VFSS should be considered.
