When the Clock Strikes A-fib.

Within the broad spectrum of atrial fibrillation (AF) symptomatology, there is a striking subset of patients with predominant or even solitary nocturnal onset of the arrhythmia. This review covers AF with nocturnal onset, with the aim of defining this distinctive subgroup among patients with AF. A periodicity analysis is provided showing a clear increased onset between 10:00 pm and 7:00 am. Multiple interacting mechanisms are discussed, such as circadian modulation of electrophysiological properties, vagal tone, and sleep disorders, as well as the potential interaction and synergism between these factors, to provide a better understanding of this clinical entity. Lastly, potential therapeutic targets for AF with nocturnal onset are addressed such as upstream therapy for underlying comorbidities, type of drug and timing of drug administration and pulmonary vein isolation, ablation of the ganglionated plexus, and autonomic nervous system modulation. Understanding the underlying AF mechanisms in the individual patient with nocturnal onset will contribute to patient-specific therapy.

Challenges of Positive Airway Pressure Treatment for Patients With Obstructive Sleep Apnea at a Veterans Medical Center.

OBJECTIVE: Positive airway pressure (PAP) compliance is important in treating obstructive sleep apnea. Previous studies have suggested that patients with economic burdens, discomfort using machines, and insufficient education have difficulty tolerating PAP machines. This study explored the factors affecting short-term adherence to PAP in a veterans medical center. METHODS: The medical records of patients who underwent polysomnography at the Veterans Health Service Medical Center, Seoul, Republic of Korea, between July 2018 and January 2021 were reviewed retrospectively. Patients with an apnea-hypopnea index (AHI) ≥15 were included (n=579). PAP adherence was defined as continuous use for ≥21 days for ≥4 hours daily for 30 consecutive days for 90 days from the date of PAP prescription. RESULTS: The PAP-adherent group (n=265, age 66.16±11.28 years) was younger and had more years of education, higher body mass indices, and lower scores in the Insomnia Severity Index and Beck Depression Inventory-II (BDI-II) than those of the PAP-nonadherent group (n=314, age 68.93±10.91 years). Patients who tolerated PAP had a higher AHI, longer duration of oxygen desaturation (less than 90%), and less dream enactment behavior (DEB) than that in those who did not. After adjusting for age, years of education, BDI-II, duration of oxygen desaturation, and presence of DEB, there were more patients with National Health Insurance (NHI) in the PAP-adherent group than in the PAP-nonadherent group (p<0.001). CONCLUSION: We showed that patients with NHI recorded significantly higher adherence compared to that in patients without NHI, among other factors.

The Association of Obstructive Sleep Apnea with Urological Cancer Incidence and Mortality-A Systematic Review and Meta-analysis.

BACKGROUND AND OBJECTIVE: While obstructive sleep apnea (OSA) and urological cancer are both strongly associated with hypoxia, controversy exists regarding their association with each other. This study aims to summarize and synthesize evidence to clarify the association between OSA and urological cancer incidence and mortality. METHODS: According to a prespecified protocol, PubMed, Embase, Cochrane Library, and Scopus were searched from inception to November 16, 2023, for observational and randomized studies reporting the association of OSA with urological cancer incidence or mortality. We pooled maximally covariate-adjusted hazard ratios (HRs) using a random-effects inverse variance-weighted model. Two reviewers independently assessed the quality of evidence using the Newcastle-Ottawa Scale and the Grading of Recommendations, Assessment, Development and Evaluation framework. KEY FINDINGS AND LIMITATIONS: From 1814 records, we included 12 studies comprising 9 290 818 participants in total, of which nine studies were analyzed quantitatively. OSA patients had an increased risk of kidney (HR: 1.75, 95% confidence interval [CI]: 1.21-2.53) and bladder (HR: 1.76, 95% CI: 1.05-2.96) cancer. However, OSA was not associated with prostate cancer incidence (HR: 1.29, 95% CI: 0.82-2.04). We systematically reviewed evidence surrounding OSA and testicular cancer incidence and urological cancer mortality. CONCLUSIONS AND CLINICAL IMPLICATIONS: OSA may be associated with a higher risk of kidney and bladder cancer, but not prostate cancer. Future work may help clarify the possibility of a dose-response relationship between OSA and urological cancer, and the effect of OSA treatment on urological cancer incidence or progression. PATIENT SUMMARY: This research highlights a potential longitudinal association between OSA and kidney and bladder cancer, but not prostate cancer.

GDF11 (Protein of Juvenility) and GDF15 (Protein of Senility) in the Plasma of Patients with Sleep Apnea Syndrome: a Pilot Study.

We performed a matched-pair analysis of the content of GDF11 and GDF15 proteins in the plasma of patients (56 middle-aged men) with obstructive sleep apnea syndrome (OSAS) and healthy volunteers (27 men with no complaints of sleep disorders). The groups were comparable in terms of age and presence of chronic diseases. No statistically significant differences in GDF11 content in the studied groups were revealed, while the content of GDF15 in the OSAS group was 1.3 times higher. These results require further research from the viewpoint of geriatric somnology and molecular biology.

A Common CHAT Gene Mutation of Congenital Myasthenic Syndrome Found in Kadazandusun Children.

Congenital myasthenic syndrome (CMS) is an uncommon inherited neuromuscular junction disease. The clinical presentation of this disorder is diverse. Typically patients with this disorder present with early-onset swallowing difficulty and apnea in infancy, fluctuating ocular palsies and fatigable proximal muscle weakness during childhood, and late-onset form involving progressive weakness in adulthood. Difficulty in performing neurophysiology studies in children and the absence of a pathognomonic investigation marker increase the challenges in diagnosis of this disorder. The emergence of next-generation sequencing technology has circumvented these challenges somewhat, and has contributed to the discovery of novel mutations. We present here diagnostic odyssey of three CMS patients from two unrelated Kadazandusun kinships and their follow-up treatment. A rare homozygous mutation c.916G > C (p.Val306Leu) in CHAT gene was found in two siblings born of a consanguineous marriage. Third patient had compound heterozygous mutations c.406G > A (p.Val136Met) and c.916G > C (p.Val306Leu) in CHAT gene. We postulate that p.Val306Leu may be a founder mutation in the Kadazandusuns, an indigenous ethnic minority of Borneo Island.

Novel Susceptibility Genes and Biomarkers for Obstructive Sleep Apnea: Insights from Genetic and Inflammatory Proteins.

STUDY OBJECTIVES: Numerous observational studies link obstructive sleep apnea (OSA) to inflammatory proteins, yet the directionality of these associations remains ambiguous. Therefore, we aimed to clarify the potential associations of gene-predicted inflammatory proteins with OSA. METHODS: Based on genome-wide association study data, we applied Mendelian randomization (MR) to explore potential connections between circulating inflammatory proteins and OSA, primarily using the inverse variance weighting method for robustness. Cochran's Q test, MR‒Egger intercept test, MR-PRESSO, and leave-one-out method were used to perform sensitivity tests for pleiotropy and heterogeneity. Replication analyses and meta-analyses were performed using other independent data. Steiger tests and multivariate MR assessed the independent effects of exposure factors, and the functional mapping and annotation (FUMA) platform was used to identify key genes to enhance the understanding of genetics. RESULTS: Our investigation revealed 21 circulating inflammatory proteins significantly associated with OSA-related phenotypes. Notably, IL-10RA, IL-18R1, TNFSF14, CCL23, ADA, and SLAMF1 had significant effects on multiple phenotypes. After FDR correction, IL-18R1, SLAMF1, IL-10RA, and IL-17C were identified as important candidates for OSA, and multivariate MR analysis strengthened the independent heritability of 20 inflammatory factors. The FUMA platform revealed seven overlapping genes: ROBO1, PRIM1, NACA, SHBG, HSD17B6, RBMS2, and WWOX. All reverse MR analyses and sensitivity analyses confirmed the robustness of these associations. CONCLUSIONS: Our results underscore crucial associations between inflammatory proteins and OSA pathogenesis, revealing new correlates and susceptibility genes. These findings advance biomarker identification for OSA risk and highlight the importance of genetic and inflammatory profiles in OSA management.

Obstructive sleep apnea and hypertension; critical overview.

Obstructive sleep apnea (OSA) and hypertension are two important modifiable risk factors for cardiovascular disease and mortality. Numerous studies have highlighted the interplay between these two conditions. We provide a critical review of the current literature on the role of the OSA as a risk factor for hypertension and its effect on blood pressure (BP). We discuss several key topics: the effect of OSA on nocturnal BP, BP response to continuous positive airway pressure (CPAP) treatment, CPAP effect on BP in refractory hypertension, the role of OSA in BP variability (BPV), and maladaptive cardiac remodeling mediated by OSA's effect on BP. Finally, we discuss the unique aspects of ethnicity and social determinants of health on OSA with a focus on Asian populations and the disparity in BP control and cardiovascular outcomes.

Supine or non-supine sleep apnea events: which can be treated better with Barbed Pharyngoplasty?

PURPOSE: Among the treatment options for Obstructive Sleep Apnea (OSA), intrapharyngeal surgery has undergone significant changes and received solid scientific support. However, it is crucial to identify the best candidate. This study aims to present the results of the modified Alianza technique in our clinic to show the differences in the impact of surgery on supine and non-supine apnea levels in moderate-severe OSA patients. METHODS: Adult patients affected by moderate-severe OSA (Apnea-Hypopnea Index (AHI) > 15), having circular palatal collapse, and candidates for modified Alianza Tecnique were retrospectively enrolled. Each subject performed polysomnography pre- and post-operatively, and the follow-up check was performed after at least six months. RESULTS: This study enrolled 24 patients who underwent the Modified Alianza technique for sleep apnea. We found significant reductions in both supine and non-supine AH) after surgery. Non-supine AHI showed a greater reduction (from 20.89 to 11.64 episodes/hour, p = 0.0001) than supine AHI (from 42.51 to 25.93, p = 0.0003). We subsequently divided the patients into two groups based on whether they were affected by positional OSA before surgery. There was a lower percentage decrease in non-supine AHI compared to supine AHI after surgery in patients who were positional before surgery, but this difference was not statistically significant. Conversely, in the non-positional patient group, there was a higher decrease in non-supine AHI compared to supine AHI, although this was not statistically significant. CONCLUSION: The Modified Alianza Tecnique leads to notable enhancement in AHI among patients with OSA. Non-supine apneas exhibit a more favorable response to the surgery than supine apneas.

A meta-analysis of the correlation between obstructive sleep apnea syndrome and renal injury.

OBJECTIVE: To conduct a meta-analysis on the correlation between obstructive sleep apnea syndrome (OSAS) and renal injury. METHODS: Literature search was carried out in PubMed, Embase and Ovid-Medline databases between the date of database establishment and June 30th 2024. The keywords included obstructive sleep apnea hypopnea syndrome, sleep apnea hypopnea syndrome, renal injury, and correlation. Two researchers 1st independently screened the titles and abstracts based on the eligibility criteria, then extracted the data and evaluated the quality, and used Review Manager 5.3 for data processing. All analysis methods were based on PRISMA. RESULTS: Finally, 8 studies that matched the inclusion criteria were included, and the relationship between obstructive sleep apnea syndrome and serum cystatin C was analyzed. The homogeneity test showed (P < 0.01, I2 = 98%), and from the meta-analysis results, it could be known that the level of serum cystatin C in sufferers with OSAS was obviously greater than the control one (OR = 1.12, 95% CI 0.96-1.28, P < 0.01). The relationship between OSAS and serum creatinine was analyzed, and homogeneity test showed (P < 0.01, I2 = 96%). From the meta analysis result, it could be known that the serum creatinine level of obstructive sleep apnea syndrome was obviously greater than the control one (OR = 1.01, 95% CI 0.85 ~ 1.17, P < 0.01). The relationship between obstructive sleep apnea syndrome with serum urea nitrogen was analyzed, and homogeneity test showed (P < 0.01, I2 = 91%). From the meta-analysis results, it could be known that serum urea nitrogen of OSAS was obviously greater than the control one (OR = 1.38, 95% CI 01.17 ~ 1.59, P < 0.01). CONCLUSIONS: Eight articles have been included to determine the correlation between obstructive sleep apnea syndrome and renal injury, and it has been found that obstructive sleep apnea syndrome is closely related to renal injury, and the two may be risk factors for each other.

Characterisation of sleep apneas and respiratory circuitry in mice lacking CDKL5.

CDKL5 deficiency disorder is a rare genetic disease caused by mutations in the CDKL5 gene. Central apneas during wakefulness have been reported in patients with CDKL5 deficiency disorder. Studies on CDKL5-knockout mice, a CDKL5 deficiency disorder model, reported sleep apneas, but it is still unclear whether these events are central (central sleep apnea) or obstructive (obstructive sleep apnea) and may be related to alterations of brain circuits that modulate breathing rhythm. This study aimed to discriminate central sleep apnea and obstructive sleep apnea in CDKL5-knockout mice, and explore changes in the somatostatin neurons expressing high levels of neurokinin-1 receptors within the preBötzinger complex. Ten adult male wild-type and 12 CDKL5-knockout mice underwent electrode implantation for sleep stage discrimination and diaphragmatic activity recording, and were studied using whole-body plethysmography for 7 hr during the light (resting) period. Sleep apneas were categorised as central sleep apnea or obstructive sleep apnea based on the recorded signals. The number of somatostatin neurons in the preBötzinger complex and their neurokinin-1 receptors expression were assessed through immunohistochemistry in a sub-group of animals. CDKL5-knockout mice exhibited a higher apnea occurrence rate and a greater prevalence of obstructive sleep apnea during rapid eye movement sleep, compared with wild-type, whereas no significant difference was observed for central sleep apnea. Moreover, CDKL5-knockout mice showed a reduced number of somatostatin neurons in the preBötzinger complex, and these neurons expressed a lower level of neurokinin-1 receptors compared with wild-type controls. These findings underscore the pivotal role of CDKL5 in regulating normal breathing, suggesting its potential involvement in shaping preBötzinger complex neural circuitry and controlling respiratory muscles during sleep.

Feasibility and usability of three consecutive nights with self-applied, home polysomnography.

In-laboratory polysomnography, the gold-standard for diagnosing sleep disorders, is resource-demanding and not conducive to multiple night evaluations. Ambulatory polysomnography, especially when self-applied, could be a viable alternative. This study aimed to assess the feasibility and reliability of self-applied polysomnography over three consecutive nights in untrained participants, assessing: technical success rate; comparing sleep diagnostic variables from single and multiple nights; and evaluating participants' subjective experience. Data were collected from 78 participants (55.1% females) invited to test a self-applicable polysomnography device for three consecutive nights at home. The technical success rate for valid sleep recordings was 82.5% out of 234 planned study nights, with 87.2% of participants obtaining at least two valid nights. Misclassification of obstructive sleep apnea severity was higher in participants with mild OSA (21.4%) compared with those with moderate-to-severe obstructive sleep apnea or no obstructive sleep apnea. Sleep efficiency and wake after sleep onset showed improvement from Night 1 to Night 3 (p < 0.001), and the mean polysomnography set-up time decreased significantly over this period. Participants reported moderate-to-high satisfaction with the device (System Usability Scale score 71.2 ± 12.4). The findings suggest that self-applied polysomnography is a feasible diagnostic method for untrained individuals at risk for sleep disorders, and that multiple night assessments can improve diagnostic precision for mild obstructive sleep apnea cases.

Establishment and validation of a prediction model for apnea on bronchiolitis.

Objective: The objective of this study is to examine the risk factors associated with apnea in hospitalized patients diagnosed with bronchiolitis and to develop a nomogram prediction model for the early identification of patients who are at risk of developing apnea. Methods: The clinical data of patients diagnosed with acute bronchiolitis and hospitalized at the Children's Hospital of Nanjing Medical University between February 2018 and May 2021 were retrospectively analyzed. LASSO regression and logistic regression analysis were used to determine the risk factors for apnea in these patients. A nomogram was constructed based on variables selected through multivariable logistic regression analysis. Receiver operating characteristic (ROC) curve and calibration curve were used to assess the accuracy and discriminative ability of the nomogram model, and decision curve analysis (DCA) was performed to evaluate the model's performance and clinical effectiveness. Results: A retrospective analysis was conducted on 613 children hospitalized with bronchiolitis, among whom 53 (8.6%) experienced apnea. The results of Lasso regression and Logistic regression analyses showed that underlying diseases, feeding difficulties, tachypnea, WBC count, and lung consolidation were independent risk factors for apnea. A nomogram prediction model was constructed based on the five predictors mentioned above. After internal validation, the nomogram model demonstrated an AUC of 0.969 (95% CI 0.951-0.987), indicating strong predictive performance for apnea in bronchiolitis. Calibration curve analysis confirmed that the nomogram prediction model had good calibration, and the clinical decision curve analysis (DCA) indicated that the nomogram was clinically useful in estimating the net benefit to patients. Conclusion: In this study, a nomogram model was developed to predict the risk of apnea in hospitalized children with bronchiolitis. The model showed good predictive performance and clinical applicability, allowing for timely identification and intensified monitoring and treatment of high-risk patients to improve overall clinical prognosis.

Gender medicine and sleep disorders: from basic science to clinical research.

Several pivotal differences in sleep and sleep disorders are recognized between women and men. This is not only due to changes in hormonal balance during women's reproductive life, such as in pregnancy and menopause. Women are more likely to report insomnia and non-specific symptoms of apneas, such as fatigue or mood disturbance, compared to men. Thus, it is important for clinicians and researchers to take sex and gender differences into account when addressing sleep disorders in order to acknowledge the biology unique to women. We present a narrative review that delves into the primary sleep disorders, starting from basic science, to explore the impact of gender differences on sleep and the current status of research on women's sleep health.

The Causal Association Between Obstructive Sleep Apnea and Child-Onset Asthma Come to Light: A Mendelian Randomization Study.

Purpose: Obstructive sleep apnea (OSA) had been associated with asthma in observational studies, but the effect of OSA on the onset of asthma in childhood or adulthood remains unclear, and the causal inferences have not been confirmed. This study aims to investigate the potential causal association between OSA with asthma, including different age-of-onset subtypes, providing reliable basis for the clinical treatment of OSA and asthma. Patients and Methods: Causality between OSA and asthma was assessed using a two-sample bi-directional Mendelian randomization (MR) analysis. OSA data were obtained from the FinnGen consortium R9, while asthma and its subtypes (adult-onset asthma, child-onset asthma, and moderate-to-severe asthma) were sourced from the IEU OpenGWAS project. The inverse-variance weighted (IVW) method was chosen as the primary analysis and was complemented by various sensitivity analyses. The MR-PRESSO outlier test was employed to systematically identify and remove outlier variants, mitigating heterogeneity and potential effects of horizontal pleiotropy. Results: The MR analyses provided evidence of genetically predicted OSA having a promoting effect on child-onset asthma (OR,1.49; 95% CI, 1.05-2.11; P=0.025) and moderate-to-severe asthma (OR,1.03; 95% CI, 1.00-1.06; P=0.046). However, no causal association between OSA with asthma and adult-onset asthma was observed. Conclusion: Our study revealed a causal association between OSA and child asthma, but not in adults. Moderate-to-severe asthma may have a potential promoting effect on OSA. These findings underscore the importance of age-specific considerations in managing asthma and suggests the need for personalized approaches in clinical practice.

Associations Between Obstructive Sleep Apnea Syndrome, Dry Eye Disease, and CPAP Usage Among Taiwanese Patients: A Retrospective Analysis.

Study Objectives: To evaluate the association between obstructive sleep apnea (OSA) and dry eye disease (DED) and analyze the impact of Continuous Positive Airway Pressure (CPAP) on DED. Methods: This is a retrospective population-based case-control study. Patients who underwent polysomnography in Taiwan from March 1, 2009, to March 1, 2020, were identified from the database of a sleep center. Patients who were diagnosed with keratoconjunctivitis sicca or tear film insufficiency were included. Patients without data from Schirmer's test, lacking tear break-up time values, or with a history of refractive surgery, Sjögren's syndrome, ocular injuries, or a disability in eyelid closure were excluded. All patients with DED enrolled had DED in both eyes. OSA severity between patients with and without DED was compared. Results: In total, 86 patients with DED and 86 age-matched patients without DED were enrolled. Significant differences in apnea-hypopnea index values (patients with DED: 29.1 ± 23.4, patients without DED: 17.9 ± 20.2, P < 0.001), OSA severity (P < 0.001), and lowest oxygen saturation (P = 0.040) between patients with and without DED were observed. A multivariate logistic regression model indicated that the use of CPAP was independently associated with DED after adjustments for OSA severity. Patients undergoing CPAP were at greater risk of developing DED than those not undergoing CPAP (Odds ratio: 3.93, 95% confidence interval: 1.47-10.49, P = 0.006). Conclusion: OSA severity is associated with DED and might be attributed to the use of CPAP.

Multiple Allergic Rhinitis Single Nucleotide Polymorphism Variants are Associated with Sleep-Breathing Parameters in Men with Obstructive Sleep Apnea: A Large-Scale Study.

Background: Sleep-disordered breathing is more prevalent in individuals with allergic rhinitis (AR) than in those without AR. In addition to increased risk for sleep-disordered breathing, AR is associated with greater severity of obstructive sleep apnea (OSA) symptoms. The aim of this research study was to evaluate the association of multiple single nucleotide polymorphism (SNP) variations in AR with sleep- and breathing-related parameters in men with OSA. Methods: Men who had complained of snoring were consecutively enrolled in the Shanghai Sleep Health Study of Shanghai Sixth People's Hospital from 2007 to 2018. After rigorous screening, 5322 men were included in the analysis. Anthropometric, fasting biochemical, and polysomnographic parameters, along with 27 AR-associated SNPs were analyzed. The associations between AR-related genetic polymorphisms and OSA were determined via linear, binary, and multinomial logistic regression analyses. Results: Rs12509403 had significantly positive associations with most sleep-breathing parameters. While the risk for OSA was increased by rs12509403, it was decreased by rs7717955 [odds ratio (OR) = 1.341, 95% confidence interval [CI] = 1.039-1.732, P = 0.024; OR = 0.829, 95% CI = 0.715-0.961, P = 0.013, respectively]. A graded increase in the risk of being in the highest quartile (Q4) vs the reference category (Q1) for sleep breathing indicators, especially REM-AHI and NREM-AHI, was identified by rs12509403 (OR = 1.496, 95% CI = 1.175-1.904, P = 0.001; OR = 1.471, 95% CI = 1.151-1.879, P < 0.001, respectively). Conclusion: The association of multiple AR SNPs with OSA-related hypoxia and sleep indices provides a genetic explanation for the higher AR susceptibility of OSA patients. Understanding the AR-related genetic underpinnings of OSA may lead to more personalized treatment approaches.

Small airway resistance in obese and nonobese patients with obstructive sleep apnea syndrome using impulse oscillometry.

Background/aim: There is limited information on the pathologic changes in the small airways among obese and nonobese patients with obstructive sleep apnea syndrome (OSAS). Impulse oscillometry (IOS) measures airway resistance and reactance independently of patient effort. This study aimed to compare airway resistance in small airways using IOS between obese and nonobese patients with OSAS. Materials and methods: In this real-life cross-sectional study, demographic information was collected from obese and nonobese subjects diagnosed with moderate and severe OSAS without any other underlying diseases. Spirometry and IOS measurements were conducted, and the values of both groups were statistically analyzed. Results: The nonobese group had a mean age of 45.6 ± 11.7 years (median 45), while the obese group had a mean age of 48.4 ± 9.5 years (median 47.5). The mean body mass index (BMI) for the nonobese group was 26.2 ± 2.1 kg/m2 (median 27 kg/m2), and for the obese group, it was 35.6 ± 6.4 kg/m2 (median 33 kg/m2). Statistically significant differences were observed between the two groups in R5 - R20 percentage, reactance area (AX), and resonant frequency (Fres) values (p < 0.05). Conclusion: Among obese OSAS patients, there is an increase in resistance in small airways as indicated by IOS values. IOS shows promise as a potential screening tool for diagnosing OSAS.

Food insecurity and the risk of sleep disorders in people living with HIV/AIDS as a neglected health concern: A national survey in Iran.

Food insecurity (FI) and sleep problems are major modifiable health issues among people living with HIV/AIDS (PLWH), and there is limited knowledge about their prevalence among this underrepresented population. Our study aimed to assess the relationship between FI and sleep problems as important environmental factors affecting PLWH in Iran. The national survey was conducted on 1185 confirmed HIV-positive patients who attended consulting centers in 15 geographically diverse provinces in Iran, during 2021-2022. Standard questionnaires were used to measure FI and sleep problems (Insomnia, Obstructive Sleep apnea (OSA), Excessive Daytime Sleepiness (EDS), and Poor sleep quality), and a logistic regression model was used to assess the association between FI and the odds of experiencing sleep problems. About 764 (The prevalence of FI = 64.47 %) of the participants had insecure status, with a mean score of 11.73 (SE = 0.34). Those with FI had a higher prevalence of insomnia, EDS, and poor sleep quality (54.84 %, 31.79 %, and 55.17 %, respectively) compared to those without FI (30.69 %, 17.03 %, and 40.42 %, respectively). FI increased the odds of being at risk for Insomnia (OR = 2.39, 95 % CI: 1.81-3.15), EDS (OR = 1.44, 95 % CI: 1.04-2.01), and poor sleep quality (OR = 1.79, 95 % CI: 1.29-2.48) in the multiple regression model. The results highlight the strong association between FI and a broad range of sleep problems in PLWH. Considering the impact of FI and impaired sleep health on PLWH, more attention is needed for at-risk groups for screening and intervention purposes.

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.

Comparative analysis of pain outcomes in hypoglossal nerve stimulation: Avoiding the digastric tendon.

OBJECTIVE: Upper airway stimulation effectively treats patients with obstructive sleep apnea, especially among those with low long-term compliance with continuous positive airway pressure. Traditional methods to implant the hypoglossal nerve stimulator involve retraction of the digastric tendon to identify the nerve and improve exposure for stimulator implantation. Transient submental pain and discomfort are known side effects of the procedure. Placement without retraction provides an alternative approach to minimize postoperative pain. This study compares post-operative pain outcomes of patients in whom the digastric tendon was and was not retracted. METHODS: Retrospective chart review of patients who received the hypoglossal nerve stimulation implant at a single institution between 2017 and 2021. A combination of descriptive and qualitative data, including age, gender, comorbidities, and postoperative symptoms are analyzed to characterize patient outcomes resulting from this intraoperative technique. The categorical and continuous variables were analyzed using chi-squared tests and independent t-tests, respectively. RESULTS: Patients report overall satisfaction after implantation and titration. A total of 108 patients underwent HGNS implantation between September 2017 and January 2021 using the aforementioned techniques. 1.69 % of patients experienced postoperative submental pain as compared to 18.37 % prior to the change in technique (p < 0.01). CONCLUSION: Avoidance of digastric tendon retraction in the implantation of the stimulating lead is a safe and effective technique that reduces postoperative pain and discomfort. Our institution has demonstrated an alternative technique for hypoglossal stimulator implantation which improves perioperative outcomes. LAY SUMMARY: Upper airway stimulation is an effective treatment for obstructive sleep apnea. During surgery, the digastric tendon is often moved to identify the nerve and improve access. This study shows that avoiding digastric tendon movement safely reduces postoperative pain and discomfort. LEVEL OF EVIDENCE: III.
