inSPIRE: An Open-Source Tool for Increased Mass Spectrometry Identification Rates Using Prosit Spectral Prediction.

Rescoring of mass spectrometry (MS) search results using spectral predictors can strongly increase peptide spectrum match (PSM) identification rates. This approach is particularly effective when aiming to search MS data against large databases, for example, when dealing with nonspecific cleavage in immunopeptidomics or inflation of the reference database for noncanonical peptide identification. Here, we present inSPIRE (in silico Spectral Predictor Informed REscoring), a flexible and performant open-source rescoring pipeline built on Prosit MS spectral prediction, which is compatible with common database search engines. inSPIRE allows large-scale rescoring with data from multiple MS search files, increases sensitivity to minor differences in amino acid residue position, and can be applied to various MS sample types, including tryptic proteome digestions and immunopeptidomes. inSPIRE boosts PSM identification rates in immunopeptidomics, leading to better performance than the original Prosit rescoring pipeline, as confirmed by benchmarking of inSPIRE performance on ground truth datasets. The integration of various features in the inSPIRE backbone further boosts the PSM identification in immunopeptidomics, with a potential benefit for the identification of noncanonical peptides.

Addressing the gaps: What social media tells us about patient experiences with hypoglossal nerve stimulation.

PURPOSE: Hypoglossal nerve stimulation (HNS) can be an effective treatment for moderate to severe obstructive sleep apnea (OSA) in positive airway pressure (PAP) intolerant patients. To better understand patient perceptions of HNS therapy, we explored three Facebook groups pertaining to HNS therapy. MATERIALS AND METHODS: A retrospective analysis of Facebook posts from three HNS-related Facebook groups, from October 1, 2022 to October 1, 2023, was performed. Posts were analyzed for author attitude, content (adverse events, inquiries, or sharing information), and the inclusion of media within the post. RESULTS: From 737 Facebook posts, 752 events were identified, predominantly authored by patients or family (99.5 %). Few posts included media attachments (7.3 %), primarily photos (85.5 %). Post tone was mainly neutral (79.4 %), rather than positive (12.9 %) or negative (7.7 %). Most posts (53.6 %) were queries to the Facebook group, as opposed to sharing information (28.9 %) or detailing adverse events (17.6 %). Notably queries posed by Facebook group members included those pertaining to the postoperative recovery course (10.17 %), physical activity restrictions (6.20 %), HNS therapy eligibility (4.71 %), financial considerations (4.22 %), and more. CONCLUSION: Overall, Facebook group members reported a predominantly neutral tone, typically posting queries to the group rather than sharing information or detailing adverse events. These findings illustrate how diverse data sources, such as social media, can enhance our understanding of patient experiences and identify gaps in patient education with HNS therapy.

Cost-Effectiveness of Endovascular Thrombectomy in M2 Occlusion Stroke: Real-World Experience Versus Clinical Trials.

OBJECTIVES: This study sought to establish the cost-effectiveness of endovascular thrombectomy (EVT) in M2 occlusions compared with patients who did not have EVT using both real-world and clinical trial evidence. METHODS: The effectiveness of EVT in M2 occlusions was informed by the International Stroke Perfusion Imaging Registry (INSPIRE, real-world data for a wide range of strokes) and HERMES collaboration, trial data. Patients who received EVT and non-EVT treatment from INSPIRE were matched according to baseline characteristics. A Markov model with 7 health states defined by the 3-month modified Rankin scale (mRS) was constructed. Endovascular thrombectomy and non-EVT-treated patients in real-world, and clinical trials were run through the Markov model separately to generate the results from a limited societal perspective. National statistics and published literature informed the long-term probability of recurrent stroke, mortality, costs of management post-stroke, non-medical care, and nursing home care. RESULTS: A total of 83 (42 EVT and 41 non-EVT) patients were matched of 278 (45 EVT and 233 non-EVT) patients in INSPIRE who had M2 occlusion stroke at presentation. The long-term simulation estimated that offering EVT to M2 occlusion stroke patients was associated with greater benefits (5.48 EVT vs 5.24 non-EVT quality-adjusted life year [QALY]) and higher costs (A$133 457 EVT vs A$126 127 non-EVT) compared with non-EVT treatment in real-world from a limited societal perspective. The incremental cost-effectiveness ratio (ICER) of EVT in real-world was A$29 981 (€19 488)/QALY. The analysis using the data from HERMES collaboration yielded consistent results for the EVT patients. Comparison with real-world cost-effectiveness analyses of EVT in internal carotid artery/middle cerebral artery-M1 (ICA/MCA-M1) occlusion suggested a potential reduced QALY gains and increased ICER in M2 occlusions. CONCLUSIONS: Our study suggested that the benefits gained from EVT in M2 occlusion stroke in the real-world were similar to that derived from the clinical trials. The clinical and cost benefits from EVT appeared to be reduced in M2 compared with that from the ICA/MCA-M1 occlusions. CLINICAL IMPACT: Our study has provided valuable insights into the clinical significance of endovascular therapy (EVT) in the context of M2 occlusion stroke within a real-world setting. It is noteworthy that our findings indicate that the benefits obtained from EVT in M2 occlusion stroke closely align with those observed in controlled clinical trials. However, it is essential to recognize that there is a reduction in the clinical and cost-related advantages when comparing M2 occlusions to more proximal ICA/MCA-M1 occlusions.

The effect of velar collapse patterns on unilateral upper airway stimulation therapy.

PURPOSE: Hypoglossal nerve stimulation is a promising alternative therapy for patients with obstructive sleep apnea with continuous positive airway pressure intolerance or failure. Previous studies concluded that a velar complete concentric collapse might prohibit a good therapeutic outcome. However, certain patients have an upper velar anteroposterior collapse and a lower velar complete concentric collapse. The effect of this velar collapse pattern is unknown, preventing evidence-based decision-making for these patients. This study aimed to compare the results of upper airway stimulation therapy in these patients to patients with a pure anteroposterior velar collapse. METHODS: A retrospective single-center cohort study was performed. Patients were included who were implanted with an upper airway stimulation device and had a 1-year follow-up. RESULTS: Of 66 patients, 10 had an upper velar anteroposterior collapse and lower velar complete concentric collapse. Fifty-six patients had a complete or partial velar anteroposterior collapse. At follow-up, all respiratory outcomes were similarly changed between the two groups. The mean apnea and hypopnea index reduced equally (26.9 events/hour vs. 23.9 events/hour, 95% CI (-5.0, 11.0), p = 0.46). A similar decrease in the oxygen desaturation index of ≥ 4% was observed (12.0/hour versus 11.5/hour, 95% CI (-8.7, 9.7) p = 0.92) CONCLUSION: Patients with an upper velar anteroposterior collapse and a lower velar complete concentric collapse are suitable candidates for upper airway stimulation therapy. In these patients, the lower velum may represent a transition zone between the anteroposterior collapse of the upper velum and the lateral collapse of the oropharynx, instead of being a real concentric collapse.

The prognostic utility of soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PIGF) biomarkers for predicting preeclampsia: a secondary analysis of data from the INSPIRE trial.

OBJECTIVE: To compare the prognostic performance of biomarkers soluble fms-like tyrosine kinase-1 (sFlt-1), Placental Growth Factor (PIGF), and sFlt-1/PIGF ratio as continuous values or as a binary cut-off of 38 for predicting preeclampsia (PE) within 7 days. DESIGN: Secondary analysis of a randomised clinical trial. SETTING: Oxford University Hospitals, Oxford, United Kingdom (UK). POPULATION: Pregnant women between 24+0 to 37+0 weeks of gestation with a clinical suspicion of preeclampsia. MAIN OUTCOME: Onset of preeclampsia within 7 days of the initial biomarker test. METHODS: Logistic regression model for onset of preeclampsia using: (i) sFlt-1 (ii) PIGF, (iii) sFlt-1/PIGF ratio (continuous), and (iv) sFlt-1/PIGF ratio as a cut-off above or below 38. RESULTS: Of the total 370 women, 42 (11.3%) developed PE within 7 days of screening. Models with sFlt-1 and sFlt-1/PIGF ratio (continuous) had greater overall performance than models with PIGF or with sFlt-1/PIGF ratio as a cut-off at 38 (R2: sFlt-1 = 55%, PIGF = 38%, sFlt-1/PIGF ratio = 57%, sFlt-1/PIGF ratio as cut-off at 38 model = 46%). The discrimination performance was the highest in sFlt-1 and sFlt-1/PIGF ratio (continuous) (c-statistic, sFlt-1 = 0.94, sFlt-1/PIGF ratio (continuous) = 0.94) models compared to PIGF or sFlt-1/PIGF cut-off models (c-statistic, PIGF = 0.87, sFlt-1/PIGF cut-off = 0.89). CONCLUSION: Models using continuous values of sFlt-1 only or sFlt-1/PIGF ratio had better predictive performance compared to a PIGF only or the model with sFlt-1/PIGF ratio as a cut-off at 38. Further studies based on a larger sample size are warranted to substantiate this finding.

Fuzzy Representation of Principal's Preferences in Inspire Negotiation Support System.

We consider the negotiation problem, in which an agent negotiates on behalf of a principal. Our considerations are focused on the Inspire negotiation support system in which the principal's preferences are visualised by circles. In this way, the principal describes the importance of each negotiation issue and the relative utility of each considered option. The paper proposes how this preference information may be implemented by the agent for determining a scoring function used to support decisions throughout the negotiation process. The starting point of our considerations is a discussion regarding the visualisation of the principal's preferences. We assume here that the importance of each issue and the utility of each option increases with the size of the circle representing them. The imprecise meaning of the notion of "circle size" implies that in a considered case, the utility of an option should be evaluated by a fuzzy number. The proposed utility fuzzification is justified by a simple analysis of results obtained from the empirical prenegotiation experiment. A novel method is proposed to determine trapezoidal fuzzy numbers, which evaluates an option's utility using a series of answers given by the participants of the experiment. The utilities obtained this way are applied to determine the fuzzy scoring function for an agent. By determining such a common generalised fuzzy scoring system, our approach helps agents handle the differences in human cognitive processes associated with understanding the principal's preferences. This work is the first approach to fuzzification of the preferences in the Inspire negotiation support system.

Adverse events associated with the Inspire implantable hypoglossal nerve stimulator: A MAUDE database review.

BACKGROUND: Implantable hypoglossal nerve stimulation (HNS) has been found to be a safe and effective therapy for patients with obstructive sleep apnea, and patient adherence to treatment has been found to be as high as 86% after 12 months of therapy. OBJECTIVE: The purpose of this study is to review the medical device reports (MDRs) submitted to the Food and Drug Administration's (FDA) Manufacturer and User Device Facility Experience (MAUDE) database to identify adverse events related to HNS therapy that could hinder compliance. METHODS: A search of the FDA MAUDE database was conducted using the product code "MNQ" for "Inspire stimulator for sleep apnea." Reports of adverse events associated with Inspire for sleep apnea from January 2000 to May 2020 were included for analysis. From these included reports, event variables were collected, including event setting, adverse event to patient, iatrogenic injury, device malfunction, interventions, and root causes. Results were compiled and reviewed. RESULTS: The search query yielded 180 reports that met inclusion criteria, containing a total of 196 adverse events. The most commonly reported adverse events to patients were infection (n = 50, 34.2%), neuropraxia (n = 22, 15.1%) and hematoma/seroma (n = 17, 11.6%). A total of 83 adverse events (42.3%) required reoperation. The most common reoperations performed for adverse events to patients were explantation (n = 30, 46.2%) and device repositioning/lead revision (n = 24, 36.9%), while the most common reoperation performed for device malfunctions was device replacement (n = 10, 55.6%). CONCLUSION: In attempting to further improve patient compliance, understanding these device malfunctions and adverse events related to HNS implantation or usage is crucial for the identification of potential causes of patient non-adherence.

The practicality of a two-incision surgical approach for hypoglossal nerve stimulator implantation.

INTRODUCTION: Determine the feasibility of a two-incision surgical approach to hypoglossal nerve stimulator implantation based on anatomic considerations. METHODS: Upper airway stimulation (UAS) using the Inspire system uses three implanted devices-the implantable pulse generator (IPG), stimulation lead and sensing chest wall lead. The traditional surgical approach requires three skin incisions located on the submandibular neck, anterosuperior chest wall and inferolateral chest wall. Our surgical team sought to determine the anatomic considerations of combining the two chest wall incisions into one. In order to minimize morbidity and reduce operative time, the chest wall sensing lead was placed posterolateral to the IPG site via the same incision. RESULTS: Using an adult cadaver for anatomical analysis, access to the third and fourth intercostal spaces was made more difficult by the pectoralis major humeral head and upper arm. The intercostal space was narrower, the musculature along the anterior axillary line and anterior chest wall was devoid of the innermost intercostal muscle group found more laterally. Furthermore, there were much thinner external and internal intercostal muscle components as they transitioned to a membranous layer anteriorly in comparison to the inferolateral chest wall. CONCLUSION: Lack of the innermost intercostal muscle and thinning of the external and internal intercostal muscles lateral to the IPG site leaves little barrier between the thoracic musculature and parietal pleural increasing the risk of complications such as pleurisy and pneumothorax. Given the anatomical findings, a two-incision surgical approach for UAS therapy is at higher risk for complications.

Necitumumab for the treatment of advanced non-small-cell lung cancer.

Personalized patient-precise medicine is being gradually incorporated into clinical practice for the treatment of non-small-cell lung cancer (NSCLC). The EGFR pathway has been explored as a druggable target with monoclonal antibodies such as cetuximab or necitumumab. Necitumumab is a humanized IgG1 anti-EGFR. In the Phase III SQUIRE trial, necitumumab used as first-line therapy in combination with cisplatin and gemcitabine showed a reduction in risk-of-death and a better disease control rate in advanced squamous NSCLC. Thus, necitumumab is now a new first-line treatment option in squamous NSCLC. However, further biomarker research is needed to improve patient selection. Moreover, necitumumab associated with other immunotherapy and targeted agents is currently an important area of research that may yield better outcomes for NSCLC patients.

Electroconvulsive therapy for depression in a patient with an Inspire hypoglossal nerve stimulator device for obstructive sleep apnea: A case report.

OUTCOME OBJECTIVES: METHODS: This is a case report of a patient who underwent placement and initiation of a hypoglossal nerve stimulator device in the context of receiving electroconvulsive therapy for bipolar depression between February and September 2016. To our knowledge, this has not yet been reported in the literature. Outcome measurements included successful device activation and successful device use throughout electroconvulsive therapy. RESULTS: The patient underwent successful device implantation, activation, and use without disruption throughout electroconvulsive therapy sessions. No special device deactivation was required during electroconvulsive therapy sessions. CONCLUSION: Obstructive sleep apnea is a common disorder that causes significant reduction in quality of life and is an independent risk factor for multiple comorbidities. Electroconvulsive therapy is an established treatment for medication-refractory depression with minimal risk in most patient populations. This is the first report in the literature of a patient undergoing ECT for bipolar depression with recent activation of Inspire hypoglossal nerve stimulator who had no disruption in the function of his implanted device.

Hypoglossal nerve stimulator generator migration: INSPIRE device reimplantation with parallels to cardiac implantable electronic devices.

Implantation rates of hypoglossal nerve stimulators, such as INSPIRE, are increasing. The device is still in its early stages of complication reporting, which to date includes implant related infection requiring device removal, and stimulation lead cuff dislodgement requiring replacement. Here we present a 48-year-old female who experienced generator migration and stimulator lead tension requiring an additional operation in order to resecure the generator device. This proved unsuccessful and a second surgery was performed with complete relocation of the device generator to inhibit device migration. This is the first documented case of INSPIRE migration to date, though the implant generator has comparable likeness to cardiovascular implantable electronic devices (CIEDs) where migration risk factors are better studied. Given our patient's case, we identify obesity and abundant breast tissue as potential risk factors for device migration. We believe such factors can be identified prior to initial device implantation to avoid migration and the need for surgical revision. Superior positioning of the generator proved successful, and can be a solution in those with similar body habitus as TYRX pouching and additional security sutures were ineffective. Also, for revisions requiring tunneling of the stimulation lead as in this case we recommend the use of zero degree endoscope for ease of adhesion lysis.

An In-Vitro Study Comparing the GME Handling of Two Contemporary Oxygenators.

Gaseous microemboli (GME) are a potential complication of cardiopulmonary bypass (CPB). Though it is difficult to prove that GME is the only major cause of neurological deficits, it may increase the chance of post-operative cognitive dysfunction if not removed. The objectives of this research were to compare LivaNova-Sorin Inspire (Inspire) oxygenator with a Medtronic arterial filter to the Medtronic Fusion (Fusion) oxygenator with and without a Medtronic arterial filter based on each system's ability to handle GME. The Inspire and Fusion systems were evaluated in vitro. GME handling was observed by introducing air in the sampling manifold connected to the venous return at a 60 mL bolus or 1 liter per minute (LPM). The emboli detection and classification (EDAC) system measured GME preand post-oxygenator/arterial filter. The Inspire with a filter was able to remove a statistically significant greater amount of total emboli per second during the 60 mL bolus and 1 LPM tests than the Fusion with and without an arterial filter. The Inspire with an arterial filter was more efficient in removing GME during a 60 mL bolus and 1 LPM than the Fusion and Fusion with an arterial filter. However, the Fusion with an arterial filtered performed better than the Fusion system without the arterial filter.

Next Generation Air Quality Platform: Openness and Interoperability for the Internet of Things.

The widespread diffusion of sensors, mobile devices, social media and open data are reconfiguring the way data underpinning policy and science are being produced and consumed. This in turn is creating both opportunities and challenges for policy-making and science. There can be major benefits from the deployment of the IoT in smart cities and environmental monitoring, but to realize such benefits, and reduce potential risks, there is an urgent need to address current limitations, including the interoperability of sensors, data quality, security of access and new methods for spatio-temporal analysis. Within this context, the manuscript provides an overview of the AirSensEUR project, which establishes an affordable open software/hardware multi-sensor platform, which is nonetheless able to monitor air pollution at low concentration levels. AirSensEUR is described from the perspective of interoperable data management with emphasis on possible use case scenarios, where reliable and timely air quality data would be essential.

Evaluating the INSPIRE measure of staff support for personal recovery in a Swedish psychiatric context.

BACKGROUND: Recovery is understood to be an individual process that cannot be controlled, but can be supported and facilitated at the individual, organizational and system levels. Standardized measures of recovery may play a critical role in contributing to the development of a recovery-oriented system. The INSPIRE measure is a 28-item service user-rated measure of recovery support. INSPIRE assesses both the individual preferences of the user in the recovery process and their experience of support from staff. AIM: The aim of this study was to evaluate the psychometric properties of the Swedish version of the INSPIRE measure, for potential use in Swedish mental health services and in order to promote recovery in mental illness. METHOD: The sample consisted of 85 participants from six community mental health services targeting people with a diagnosis of psychosis in a municipality in Sweden. For the test-retest evaluation, 78 participants completed the questionnaire 2 weeks later. RESULTS: The results in the present study indicate that the Swedish version of the INSPIRE measure had good face and content validity, satisfactory internal consistency and some level of instability in test-retest reliability. CONCLUSIONS: While further studies that test the instrument in a larger and more diverse clinical context are needed, INSPIRE can be considered a relevant and feasible instrument to utilize in supporting the development of a recovery-oriented system in Sweden.

Palate shape is associated with Unilateral Hypoglossal Nerve Stimulation Outcomes.

OBJECTIVE: The aim was to determine the potential association between palate shape and unilateral hypoglossal nerve stimulation (HNS) outcomes. METHODS: Preoperative drug-induced sleep endoscopy (DISE) videos were reviewed and scored by 3 blinded reviewers to determine airway narrowing at the hard-soft palate junction (HP), soft palate genu, and inferior velum, as described by Woodson (2014). Scoring was as follows: 1-open airway, 2-narrow, 3-severe narrowing. Overall palate shape (oblique, intermediate, or vertical) was determined based on prior criteria. Successful surgical treatment was defined by the HNS titration polysomnogram as a reduction of ≥50% in the apnea-hypopnea index (AHI) to <15 events/h. RESULTS: Of 332 adults, the majority was male (77%) with an average BMI of 29.2 ± 3.6 kg/m2 . Overall success rate was 73%. Success rate was lower in patients with vertical palate shape compared with the other shapes (56% vs. 75%, p = 0.029). HP score 3 compared with scores 2 and 1 was associated with lower success rates (60% vs. 76%, p = 0.028), but genu and velum scores were not associated with outcomes. Patients with both HP score 3 and complete oropharyngeal lateral wall-related obstruction had notably worse outcomes (22% vs. 74%, p = 0.026). HP score 3 (OR 0.45, 95%CI 0.22-0.92) and vertical palate shape (OR 0.33, 95%CI 0.15-0.78) were independently associated with lower odds of surgical response after adjustment for DISE findings, age, gender, and BMI. CONCLUSION: Vertical palate shape and narrowing at the hard-soft palate junction are independently associated with lower HNS surgical success rates.

Investigation of integrated time nanosecond pulse irreversible electroporation against spontaneous equine melanoma.

Introduction: Integrated time nanosecond pulse irreversible electroporation (INSPIRE) is a novel tumor ablation modality that employs high voltage, alternating polarity waveforms to induce cell death in a well-defined volume while sparing the underlying tissue. This study aimed to demonstrate the in vivo efficacy of INSPIRE against spontaneous melanoma in standing, awake horses. Methods: A custom applicator and a pulse generation system were utilized in a pilot study to treat horses presenting with spontaneous melanoma. INSPIRE treatments were administered to 32 tumors across 6 horses and an additional 13 tumors were followed to act as untreated controls. Tumors were tracked over a 43-85 day period following a single INSPIRE treatment. Pulse widths of 500ns and 2000ns with voltages between 1000 V and 2000 V were investigated to determine the effect of these variables on treatment outcomes. Results: Treatments administered at the lowest voltage (1000 V) reduced tumor volumes by 11 to 15%. Higher voltage (2000 V) treatments reduced tumor volumes by 84 to 88% and eliminated 33% and 80% of tumors when 500 ns and 2000 ns pulses were administered, respectively. Discussion: Promising results were achieved without the use of chemotherapeutics, the use of general anesthesia, or the need for surgical resection in regions which are challenging to keep sterile. This novel therapeutic approach has the potential to expand the role of pulsed electric fields in veterinary patients, especially when general anesthesia is contraindicated, and warrants future studies to demonstrate the efficacy of INSPIRE as a solid tumor treatment.

A Protocolized Approach to Awake Endoscopy With Advanced Programming to Optimize Hypoglossal Nerve Stimulation.

Hypoglossal nerve stimulation is a treatment option for patients with obstructive sleep apnea who are intolerant to positive airway pressure therapy. In the post-implant period, awake endoscopy with advanced programming (AEAP) can be employed to optimize apnea-hypopnea index reduction and/or patient comfort and usage. The report herein describes awake endoscopy with AEAP as a guide to providers involved in post-implant care. The first 5 consecutive patients were reviewed to provide general understanding of outcomes and safety when implementing such a protocolized approach.

Scalability, test-retest reliability and validity of the Brief INSPIRE-O measure of personal recovery in psychiatric services.

Introduction: Mental health services have transitioned from treating symptoms to emphasizing personal recovery. Despite its importance, integrating personal recovery into clinical practice remains work in progress. This study evaluates the psychometric qualities of the Brief INSPIRE-O, a five-item patient-reported outcome measure assessing personal recovery. Method: The study collected data from 2018 to 2020 at the Mental Health Services, Capital Region of Denmark, using an internet-based system examining 8,192 non-psychotic patients - receiving outpatient treatment. Materials: This study evaluated the Brief INSPIRE-O and used measures of symptomatology (SCL-10), well-being (WHO-5), and social functioning (modified SDS). Results: The study population comprised 76.8% females with a mean age of 32.9 years, and diagnoses included anxiety (28%), depression (34%), and personality disorder (19%). The mean Brief INSPIRE-O score (39.9) was lower than the general population norm (71.1). The Brief INSPIRE-O showed acceptable test-retest reliability (0.75), scalability (0.39), and internal consistency (0.73). Correlations with other mental health criteria were in the expected direction for symptomatology (-0.46), well-being (0.60), and social functioning (-0.43) and remained consistent across diagnoses. Discussion: The Brief INSPIRE-O demonstrated strong psychometric qualities and could be recommended as a measure of personal recovery for use in both research and clinical practice. Its strong theoretical basis and short completion time make it suitable for use for research. Incorporating Brief INSPIRE-O into clinical assessment will further support the process of mental health systems re-orientating towards personal recovery.

Treatment of Residual Palatal Collapse in Hypoglossal Nerve Stimulation Using a Palatal Device.

Hypoglossal nerve stimulation (HNS) has increasingly become an alternative therapy for obstructive sleep apnea patients with CPAP intolerance. Stimulation of the hypoglossal nerve during sleep enhances airway patency and alleviates collapse. Suboptimal responses to HNS often stem from insufficient palatal coupling and residual velar collapse. Combining palatal devices, such as Velumount®, with HNS represents a simple and cost-effective strategy to treat residual palatal collapse. Patients desiring conservative treatment for residual palatal obstruction under HNS may consider this combined approach. Laryngoscope, 134:3412-3414, 2024.

Snoring Patterns During Hypoglossal Nerve Stimulation Therapy Up-Titration.

Longitudinal snoring changes can be captured using a mobile phone application. During hypoglossal nerve stimulator (HNS) therapy up-titration, increasing stimulation voltage was associated with reduced snoring frequency and intensity in this case series of six patients.
