Results of the ADHERE upper airway stimulation registry and predictors of therapy efficacy.
OBJECTIVE/HYPOTHESIS: The ADHERE Registry is a multicenter prospective observational study following outcomes of upper airway stimulation (UAS) therapy in patients who have failed continuous positive airway pressure therapy for obstructive sleep apnea (OSA). The aim of this registry and purpose of this article were to examine the outcomes of patients receiving UAS for treatment of OSA.
STUDY DESIGN: Cohort Study.
METHODS: Demographic and sleep study data collection occurred at baseline, implantation visit, post-titration (6 months), and final visit (12 months). Patient and physician reported outcomes were also collected. Post hoc univariate and multivariate analysis was used to identify predictors of therapy response, defined as ≥50% decrease in Apnea-Hypopnea Index (AHI) and AHI ≤20 at the 12-month visit.
RESULTS: The registry has enrolled 1,017 patients from October 2016 through February 2019. Thus far, 640 patients have completed their 6-month follow-up and 382 have completed the 12-month follow-up. After 12 months, median AHI was reduced from 32.8 (interquartile range [IQR], 23.6-45.0) to 9.5 (IQR, 4.0-18.5); mean, 35.8 ± 15.4 to 14.2 ± 15.0, P \u3c .0001. Epworth Sleepiness Scale was similarly improved from 11.0 (IQR, 7-16) to 7.0 (IQR, 4-11); mean, 11.4 ± 5.6 to 7.2 ± 4.8, P \u3c .0001. Therapy usage was 5.6 ± 2.1 hours per night after 12 months. In a multivariate model, only female sex and lower baseline body mass index remained as significant predictors of therapy response.
CONCLUSIONS: Across a multi-institutional study, UAS therapy continues to show significant improvement in subjective and objective OSA outcomes. This analysis shows that the therapy effect is durable and adherence is high.

Salivary Glucose Oxidase from Caterpillars Mediates the Induction of Rapid and Delayed-Induced Defenses in the Tomato Plant
Caterpillars produce oral secretions that may serve as cues to elicit plant defenses, but in other cases these secretions have been shown to suppress plant defenses. Ongoing work in our laboratory has focused on the salivary secretions of the tomato fruitworm, Helicoverpa zea. In previous studies we have shown that saliva and its principal component glucose oxidase acts as an effector by suppressing defenses in tobacco. In this current study, we report that saliva elicits a burst of jasmonic acid (JA) and the induction of late responding defense genes such as proteinase inhibitor 2 (Pin2). Transcripts encoding early response genes associated with the JA pathway were not affected by saliva. We also observed a delayed response to saliva with increased densities of Type VI glandular trichomes in newly emerged leaves. Proteomic analysis of saliva revealed glucose oxidase (GOX) was the most abundant protein identified and we confirmed that it plays a primary role in the induction of defenses in tomato. These results suggest that the recognition of GOX in tomato may represent a case for effector-triggered immunity. Examination of saliva from other caterpillar species indicates that saliva from the noctuids Spodoptera exigua and Heliothis virescens also induced Pin2 transcripts

Hypoglossal nerve stimulation for obstructive sleep apnea: A review of the literature
Objective: To review the indications and clinical evidence supporting hypoglossal nerve stimulation (HNS) therapy for the treatment of moderate-to-severe obstructive sleep apnea (OSA). Methods: Peer reviewed literature on hypoglossal nerve stimulation therapy for obstructive sleep apnea from 2001 to 2016. Results: The only currently FDA-approved HNS device for the treatment of moderate-to-severe OSA is produced by Inspire Medical Systems, which recently published its 36-month outcomes data from its Stimulation Therapy for Apnea Reduction (STAR) trial. HNS therapy is currently indicated for moderate-to-severe OSA patients who are CPAP-intolerant, have a body mass index <32, apnea-hypopnea index <50, and without a concentric pattern of upper airway collapse on sleep endoscopy. Conclusions: Data from the STAR trial suggests that a subset of OSA patients can achieve a significant therapeutic response from hypoglossal nerve stimulation. However, these results may be limited in their generalizability to the broader OSA population.

Wound odor: current methods of treatment and need for objective measures
Chronic wounds are an enormous burden to society, costing billions of dollars annually in the USA alone. Despite the extensive research into methods to heal chronic wounds, many remain unhealed for months to years. There is a need to focus on patient reported outcomes to improve quality of life in patients with non-healing wounds. Wound odor has a significant impact on patient quality of life; however, relatively little information is available on the management of wound odor. We review the current data available on wound odor and discuss the need for standardized objective measures of odor to improve research quality. An independent search of the PubMed and Embase databases was conducted using combinations of the following words or phrases: "wounds," "chronic wounds," "diabetic ulcers," "venous leg ulcers (VLUs)," "malignant ulcers," "odor," "odour," "smell," "malodor," "artificial olfaction," "electronic nose," and "e-nose." Article references were also searched for significance. There are few overall studies on wound odor, and fewer randomized controlled trials. Current trials on odor have consistent weaknesses such as subjective measures and poor methodology. No single odor treatment modality has been demonstrated to be widely effective for wound odor or superior to other methods. Future research should incorporate objective measures of odor such as electronic noses into clinical trials

Hearing results after posterior fossa vestibular neurectomy
The effect of posterior fossa vestibular neurectomy on postoperative hearing levels of 172 patients was studied at 1 week, 1 month, 1 year, and 18 to 24 months. According to the 1985 American Academy of Otolaryngology - Head and Neck Surgery guidelines for reporting treatment outcome, 66% of patients had improved or unchanged hearing at 18 to 24 months. One-week postoperative hearing was poorer than at 1 month or later follow-up. Permanent profound hearing loss occurred in 4.7% of patients. In patients who had worse than 80 dB pure-tone average and 20% speech discrimination score hearing loss before surgery, 68% improved above this hearing level, and 16% improved to better than 50 dB pure-tone average and 50% speech discrimination after surgery. This suggests that it may be worthwhile to preserve the cochlear nerve in certain patients who may otherwise be candidates for labyrinthectomy. These hearing results are comparable with other treatment modalities including endolymphatic sac surgery.

Gender analysis of the top classic papers in otolaryngology head and neck surgery
Abstract Objective The aim of this study was to identify and analyze the gender breakdown of first authorship contributing to the most‐cited papers in the field of otolaryngology, with a goal of identifying trends in gender representation in publishing. Methods The top 150 most‐cited papers were identified using the Science Citation Index of the Institute for Scientific Information. Among the first authors, gender, h‐index, percentage of first, last, and corresponding authorship positions, total publications, and citations were analyzed. Results The majority of papers were in the English language, from the United States, of clinical nature, and on otologic topics. Eighty‐one percent of papers (n = 122) had men who were first authors, although there was no difference in h‐index score, authorship position, number of publications, citations, and average citations/year between men and women first authors. Upon subgroup analysis by decade (1950s–2010s), there was no difference in the number of articles by women first authors (P = 0.11); however, there was a statistically significant increase in the percentage of women authors (P = 0.001) in papers published later compared to those published earlier. Conclusions While a promising number of women otolaryngologists are publishing high‐powered articles, future initiatives to promote academic inclusivity of women should be considered
