Abstract
Impaired pharyngo-laryngeal sensory function is a critical mechanism for oropharyngeal dysphagia (OD). Discovery of the TRP family in sensory nerves opens a window for new active treatments for OD. To summarize our experience of the action mechanism and therapeutic effects of pharyngeal sensory stimulation by TRPV1, TRPA1 and TRPM8 agonists in older patients with OD. Summary of our studies on location and expression of TRP in the human oropharynx and larynx, and clinical trials with acute and after 2 weeks of treatment with TRP agonists in older patients with OD. (1) TRP receptors are widely expressed in the human oropharynx and larynx: TRPV1 was localized in epithelial cells and TRPV1, TRPA1 and TRPM8 in sensory fibers mainly below the basal lamina. (2) Older people present a decline in pharyngeal sensory function, more severe in patients with OD associated with delayed swallow response, impaired airway protection and reduced spontaneous swallowing frequency. (3) Acute stimulation with TRP agonists improved the biomechanics and neurophysiology of swallowing in older patients with OD TRPV1 = TRPA1 > TRPM8. (4) After 2 weeks of treatment, TRPV1 agonists induced cortical changes that correlated with improvements in swallowing biomechanics. TRP agonists are well tolerated and do not induce any major adverse events. TRP receptors are widely expressed in the human oropharynx and larynx with specific patterns. Acute oropharyngeal sensory stimulation with TRP agonists improved neurophysiology, biomechanics of swallow response, and safety of swallowing. Subacute stimulation promotes brain plasticity further improving swallow function in older people with OD.

Abstract
INTRODUCTION Degenerative cervical myelopathy (DCM) is a common and disabling condition of symptomatic cervical spinal cord compression secondary to degenerative changes in spinal structures leading to a mechanical stress injury of the spinal cord. RECEDE-Myelopathy aims to test the disease-modulating activity of the phosphodiesterase 3/phosphodiesterase 4 inhibitor Ibudilast as an adjuvant to surgical decompression in DCM. METHODS AND ANALYSIS RECEDE-Myelopathy is a multicentre, double-blind, randomised, placebo-controlled trial. Participants will be randomised to receive either 60-100 mg Ibudilast or placebo starting within 10 weeks prior to surgery and continuing for 24 weeks after surgery for a maximum of 34 weeks. Adults with DCM, who have a modified Japanese Orthopaedic Association (mJOA) score 8-14 inclusive and are scheduled for their first decompressive surgery are eligible for inclusion. The coprimary endpoints are pain measured on a visual analogue scale and physical function measured by the mJOA score at 6 months after surgery. Clinical assessments will be undertaken preoperatively, postoperatively and 3, 6 and 12 months after surgery. We hypothesise that adjuvant therapy with Ibudilast leads to a meaningful and additional improvement in either pain or function, as compared with standard routine care. STUDY DESIGN Clinical trial protocol V.2.2 October 2020. ETHICS AND DISSEMINATION Ethical approval has been obtained from HRA-Wales.The results will be presented at an international and national scientific conferences and in a peer-reviewed journals. TRIAL REGISTRATION NUMBER ISRCTN Number: ISRCTN16682024.

Abstract
Fluid thickening is the main compensatory strategy for patients with oropharyngeal dysphagia (OD) associated with aging or neurological diseases, and there is still no pharmacological treatment. We aimed to compare the effects of increasing bolus viscosity with that of acute stimulation with TRPV1, TRPA1 or TRPM8 agonists on the biomechanics and neurophysiology of swallow response in patients with OD. We retrospectively analyzed seven studies from our laboratory on 329 patients with OD. The effect of increasing shear viscosity up to 3682 mPa·s was compared by videofluoroscopy and pharyngeal sensory evoked potentials (pSEP) with that of adding to the bolus: capsaicin (TRPV1, 150 μM/10 μM), piperine (TRPA1/V1, 1 mM/150 μM), menthol (TRPM8, 1 mM/10 mM), cinnamaldehyde-zinc (TRPA1, 100 ppm−70 mM), citral (TRPA1, 250 ppm) or citral-isopulegol (TRPA1-TRPM8, 250 ppm−200 ppm). Fluid thickening improved the safety of swallow by 80% (p < 0.0001) by delaying bolus velocity by 20.7 ± 7.0% and time to laryngeal vestibule closure (LVC) by 23.1 ± 3.7%. Capsaicin 150μM or piperine 1 mM significantly improved safety of swallow by 50% (p < 0.01) and 57.1% (p < 0.01) by speeding time to LVC by 27.6% (p < 0.001) and 19.5% (p < 0.01) and bolus velocity by 24.8% (p < 0.01) and 16.9% (p < 0.05), respectively. Cinnamaldehyde-zinc shortened the P2 latency of pSEPs by 11.0% (p < 0.01) and reduced N2-P2 amplitude by 35% (p < 0.01). In conclusion, TRPV1 and TRPV1/A1 agonists are optimal candidates to develop new pharmacological strategies to promote the recovery of brain and swallow function in patients with chronic OD.

Abstract
BACKGROUND Oropharyngeal dysphagia (OD) treatment is moving away from compensatory strategies toward active treatments that improve swallowing function. The aim of this study was to assess the acute therapeutic effect of TRPA1/M8 agonists in improving swallowing function in OD patients. METHODS Fifty-eight patients with OD caused by aging, stroke, or neurodegenerative disease were included in a three-arm, quadruple-blind, randomized clinical trial (NCT02193438). Swallowing safety and efficacy and the kinematics of the swallow response were assessed by videofluoroscopy (VFS) during the swallow of 182 ± 2 mPa·s viscosity (nectar) boluses of a xanthan gum thickener supplemented with (a) 756.6 μmol/L cinnamaldehyde and 70 μmol/L zinc (CIN-Zn) (TRPA1 agonists), (b) 1.6 mmol/L citral (CIT) (TRPA1 agonist), or (c) 1.6 mmol/L citral and 1.3 mmol/L isopulegol (CIT-ISO) (TRPA1 and TRPM8 agonists). The effects on pharyngeal event-related potentials (ERP) were assessed by electroencephalography. KEY RESULTS TRPA1 stimulation with either CIN-Zn or CIT reduced time to laryngeal vestibule closure (CIN-Zn P = .002, CIT P = .023) and upper esophageal sphincter opening (CIN-Zn P = .007, CIT P = .035). In addition, CIN-Zn reduced the penetration-aspiration scale score (P = .009), increased the prevalence of safe swallows (P = .041), and reduced the latency of the P2 peak of the ERP. CIT-ISO had no positive effect on biomechanics or neurophysiology. No significant adverse events were observed. CONCLUSIONS AND INFERENCES TRPA1 stimulation with CIN-Zn or CIT improves the swallow response which, in the case of CIN-Zn, is associated with a significant improvement in cortical activation and safety of swallow. These results provide the basis for the development of new active treatments for OD using TRPA1 agonists.

Abstract
BACKGROUND Oropharyngeal dysphagia (OD) is a prevalent disease with poor prognosis among older people and has no pharmacological treatment. Polymodal sensory receptors like the TRP or ASIC family receptors are potential targets to treat OD. TRPM8 agonists and acidic solutions can improve the swallow response in patients with OD, but little is known about the expression of TRPM8, ASIC1, and ASIC3 in the human oropharynx. The aim of this study was to assess the expression and localization of TRPM8, ASIC1, and ASIC3 in human samples of the oropharynx to lay the basis for new pharmacological treatments for OD. METHODS Pathology-free samples from oropharyngeal regions innervated by cranial nerves V, IX, and X were obtained during major ENT surgery and processed to obtain mRNA (20 patients) or to be used in immunohistochemical assays (12 patients). TRPM8, ASIC1, and ASIC3 expression and localization were studied with RT-qPCR and fluorescent immunohistochemistry. KEY RESULTS ASIC3 was expressed in the 3 regions studied with similar levels and was localized on sensory fibers innervating the mucosa below the basal lamina of all studied regions. TRPM8 was also co-localized on the sensory fibers innervating the mucosa below the basal lamina of all studied regions. In contrast, ASIC1 was only found in the nerves innervating the tongue muscular fibers. CONCLUSIONS & INFERENCES TRPM8 and ASIC3 are found on submucosal sensory nerves in the human oropharynx. Our study lays the basis to use oropharyngeal TRPM8 and ASIC3 receptors as therapeutic targets to develop new active pharmacological treatments for OD patients.

Abstract
BACKGROUND Oropharyngeal dysphagia (OD) is a prevalent poststroke condition with severe complications and increased mortality. Poststroke OD prevalence varies among studies and there is little evidence of its related risk factors and associated complications. OBJECTIVE to evaluate the prevalence of OD after stroke and the risk factors and associated complications. METHODS We performed a prospective longitudinal study of stroke patients consecutively admitted to a general hospital. OD was diagnosed with the volume-viscosity swallow test (V-VST). Demographic, functional status and topographical and clinical variables of stroke were collected to assess risk factors for OD. We evaluated functional status, mortality, respiratory infections, and readmissions 3 and 12 months after stroke. A multivariate regression analysis determined associated risk factors for OD and for each outcome variable. KEY RESULTS We included 395 stroke patients with a 45.06% prevalence of OD on admission. OD was independently associated with age (OR = 1.05; CI = 1.02-1.08), previous stroke (OR = 2.40; CI = 1.00-5.79), severity using the National Institute of Health Stroke Scale (OR = 3.52; CI = 1.57-7.87) and volume of the lesion (OR = 1.02; CI = 1.01-1.03). OD after stroke was an independent risk factor for prolonged hospital stay (P = .049; β = 0.938) and institutionalization after discharge (OR = 0.47; CI = 0.24-0.92); OD was an independent risk factor for poorer functional capacity (OR = 3.00; CI = 1.58-5.68) and increased mortality (HR = 6.90; CI = 1.57-30.34) 3 months after stroke. CONCLUSIONS & INFERENCES Poststroke OD is prevalent and associated with poor short and long term prognosis. Stroke severity and patient status before stroke were more relevant to OD than lesion location. Systematic screening programs and early OD management could significantly improve poststroke patient outcome.

Abstract
BACKGROUND Oropharyngeal sensory impairment is a potential target to treat swallowing dysfunction in patients with oropharyngeal dysphagia (OD). AIM To assess the therapeutic effect of stimulating oropharyngeal sensory afferents with TRPV1, TRPA1, or TRPM8 agonists vs increasing bolus viscosity in older and neurologic patients with OD by comparing four studies of similar experimental design. METHODS Swallow function of 142 older patients with impaired safety of swallow at nectar ([50-350] mPa·s) viscosity was evaluated with videofluoroscopy (VFS) while treated with TRPV1 (150 μmol/L), TRPV1/A1 (150 μmol/L and 1 mmol/L), or TRPM8 (1 mmol/L or 10 mmol/L) agonists or modified starch (MS) at spoon thick viscosity (>1750 mPa·s). RESULTS TRPV1 stimulation with capsaicinoids reduced penetrations by 50%, pharyngeal residue by 80%, and LVC time by 24.38% and increased bolus velocity by 36.51%. TRPV1/A1 stimulation with piperine reduced penetrations by 56.32%, LVC time by 25.55% and increased bolus velocity by 23.63%. TRPM8 stimulation with menthol 1 mmol/L reduced penetrations by 37.5% while 10 mmol/L reduced LVC time by 18.44%. Thickeners reduced penetrations by 77.11%, but increased pharyngeal residue by 19.89%, delayed LVC by 41.73%, and reduced bolus velocity by 13.44%. CONCLUSION Natural capsaicinoids have a stronger therapeutic effect on VFS signs and swallow response by stimulating TRPV1 than TRPV1/A1 or TRPM8 agonists. While TRP stimulants increased bolus velocity and reduced swallow response times, thickeners reduced bolus velocity and further delayed the swallow response. This study sets the bases to develop new pharmacologic strategies for older patients with OD, moving away from compensation toward the recovery of swallow function.

Abstract
BACKGROUND Previous studies have found that TRPV1 and TRPA1 receptor agonists improve swallow response in patients with oropharyngeal dysphagia (OD), but little is known about the expression of these receptors in the human oropharynx. The aim of this study was to assess the expression and localization of TRPV1 and TRPA1 in human samples from the oropharynx of healthy patients, to provide the basis for new pharmacological treatments for OD. METHODS Samples from oropharyngeal regions innervated by cranial nerves V, IX, and X (tongue, pharynx, and epiglottis) were obtained during ENT surgery and processed either for mRNA (21 patients) or for immunohistochemical assays (seven patients). The expression analysis was performed with RT-qPCR using ACTBh as reference gene. Hemotoxylin and eosin staining was used to study the histology; the immunohistochemical assay used (i) neuron-specific enolase to detect nerve fibers or (ii) fluorescent probes to locate TRPV1 and TRPA1. RESULTS TRPV1 was expressed in the three studied regions, with higher levels in CN V region (tongue) than in CN X region (epiglottis; p < 0.05), and was localized at epithelial cells and nociceptive fibers in all studied regions. TRPA1 was also expressed in all studied regions, but was always localized below the basal lamina. No immunoreactivity for TRPA1 was found on epithelial cells. CONCLUSIONS & INFERENCES TRPV1 and TRPA1 are widely expressed in the human oropharynx with two distinct patterns. Our study further confirms that TRPV1/A1 receptors are promising therapeutic targets to develop active treatments for OD patients.

Abstract
BACKGROUND Colonic samples from asymptomatic diverticulosis (DS) patients presented enhanced electrical field stimulation (EFS)-contractions, in an earlier study of ours, suggesting increased endogenous responses. The aim of this study was to explore changes in excitatory neuromuscular transmission and to assess the pharmacodynamics of spasmolytic agents in DS. METHODS Circular muscle strips from sigmoid colon of DS patients (n = 30; 69.5 ± 14.8 years) and controls (n = 32; 64.7 ± 16.2 years) were studied using organ baths to evaluate the direct effect of excitatory agonists (carbachol, neurokinin A [NKA] and substance P [SP]), and the effect of antagonists (atropine and NK2 antagonist GR94800) and spasmolytic drugs (otilonium bromide [OB] and N-butyl-hyoscine) on the contractions induced by EFS-stimulation of excitatory motorneurons. qRT-PCR was also performed to compare mRNA expression of M2 , M3 , NK2 receptors and L-type calcium channels. KEY RESULTS Contractions to carbachol (Emax : 663.7 ± 305.6% control vs 2698.0 ± 439.5% DS; p < 0.0005) and NKA (Emax : 387.8 ± 35.6% vs 1102.0 ± 190.1%; p < 0.0005) were higher in DS group, without differences for SP. Higher potency for DS patients was observed in the concentration-response curves for atropine (pIC50 = 8.56 ± 0.15 control vs pIC50 = 9.95 ± 0.18 DS group; p < 0.005) and slightly higher for GR94800 (pIC50 = 7.21 ± 0.18 control vs pIC50 = 7.97 ± 0.32 group; p < 0.0001). Lower efficacy (Emax ) and potency (pIC50 ) was observed for spasmolytic drugs in DS, whereas no differences were found regarding the relative expression of the receptors evaluated between groups. CONCLUSIONS & INFERENCES The greater response to cholinergic and tachykinergic agonists and greater potency for muscarinic and NK2 antagonists observed in DS might play a role in the spasticity found in diverticular disease.
