Importance: Intraoperative nerve monitoring (IONM) is not considered standard of care during thyroidectomy, and guidelines are vague about its use in the absence of strong evidence of superiority over visualization of the recurrent laryngeal nerve (RLN) alone.

Objective: To characterize patterns of IONM use during thyroidectomy in the US and evaluate the association of IONM with postoperative outcomes.

Design, setting, and participants: This cohort study used the National Surgical Quality Improvement Program (NSQIP) thyroidectomy data from January 1, 2016, to December 31, 2022. A nationally representative sample included adult patients without poorly differentiated thyroid cancer who underwent thyroidectomy at multiple centers. Data were collected from the time of surgery until 30 postoperative days through January 31, 2023.

Exposure: IONM during thyroidectomy.

Main outcomes and measures: Prevalence of IONM during thyroidectomy and postoperative outcomes including RLN injury, hypocalcemia, and neck hematoma.

Results: A total of 44 265 patients undergoing thyroidectomy were included (77.2% female; mean [SD] age, 51.8 [15.2] years), with 30 633 (69.2%) using IONM. Common indications for surgery in the cohort were goiter (35.3%) and a single nodule or neoplasm (39.2%). The prevalence of IONM increased from 62.5% in 2016 to 75.9% in 2022. RLN injury occurred in 6.0% of cases. On propensity score-matched analyses, IONM was associated with decreased odds of RLN injury overall (adjusted odds ratio [AOR], 0.98; 95% CI, 0.97-0.99) and decreased odds among patients with differentiated thyroid cancer (AOR, 0.96; 95% CI, 0.94-0.99). IONM was not associated with postoperative hypocalcemia (AOR, 0.99; 95% CI, 0.99-1.00) or neck hematoma (AOR, 1.00; 95% CI, 0.99-1.00).

Conclusions and relevance: This cohort study found that IONM during thyroidectomy has become routine, and use has increased over the last 7 years. IONM was associated with a slightly decreased odds of RLN injury, but no difference in hypocalcemia or neck hematoma. Although IONM use is widespread, further research is needed to identify patients who would benefit the most from this technology.

Importance: Cochlear implants enable improvements in speech perception, but music perception outcomes remain variable. Image-guided cochlear implant programming has emerged as a potential programming strategy for increasing the quality of spectral information delivered through the cochlear implant to improve outcomes.

Objectives: To perform 2 experiments, the first of which modeled the variance in music perception scores as a function of electrode positioning factors, and the second of which evaluated image-guided cochlear implant programming as a strategy to improve music perception with a cochlear implant.

Design, setting, and participants: This single-center, prospective study recruited 50 adult patients with at least 6 months of cochlear implant listening experience and normal cochlear anatomy to participate in experiment 1 from 2013 to 2023. Data analysis was conducted from January to February 2024. Thirty-four of the 50 patients from experiment 1 also completed experiment 2.

Interventions: Cochlear implant programming using a computed tomography-guided electrode selection strategy.

Main outcomes and measures: University of Washington Clinical Assessment of Music score, including subtests of pitch discrimination thresholds, isochronous familiar melody recognition, and timbre recognition.

Results: Of 50 participants, 20 (40%) were female, and the mean (SD) age was 57.7 (16.4) years. Experiment 1 suggested that better music perception abilities in the 50 participants were associated with patients who were younger and had a postlingual onset of deafness, as well as electrode arrays with a full scala tympani insertion, higher modiolar distance, and shallower insertion depth. Experiment 2 suggested improvements in melody recognition in the 34 participants using the image-guided cochlear implant programming strategy. Patients with apical electrodes that were deactivated were more likely to demonstrate an improvement in their pitch perception thresholds with the image-guided strategy, likely due to the low-frequency stimuli used in the University of Washington Clinical Assessment of Music.

Conclusions and relevance: This study identified patient and device factors that were associated with music perception outcomes with a cochlear implant. These findings suggest that a personalized, image-guided approach to programming may improve music perception abilities for patients with cochlear implants.

Importance: Noise exposure is a major modifiable risk factor for hearing loss, yet it is not known whether it affects the rate of hearing decline in aging.

Objective: To determine the association of noise exposure history with the rate of pure-tone threshold change per year.

Design, setting, and participants: This longitudinal cohort study was conducted in the ongoing community-based Medical University of South Carolina Longitudinal Cohort Study of Age-Related Hearing Loss (1988 to present with the sample based in Charleston, South Carolina, and surrounding area). Following a comprehensive baseline examination, participants attended annual examinations, during which audiometric data were collected. Participants with audiometric data from at least 2 examinations and noise exposure history data were included in the study. Data were analyzed between September 2023 and July 2024.

Exposure: Noise exposure history, determined by a self-reported questionnaire and history of military service, was categorized as no/little, some, or high exposure.

Main outcomes and measures: Outcome measures were individual audiometric thresholds (0.25 kHz to 8.0 kHz) and pure-tone average (PTA) of thresholds at frequencies 0.5 kHz, 1.0 kHz, 2.0 kHz, and 4.0 kHz, averaged bilaterally. Linear mixed regression models were used to estimate the association of age (per every 1 additional year) with the rate of threshold change at each frequency and PTA, for each noise exposure category. The association of noise exposure with the rate of annual threshold change was determined by an interaction term of age (longitudinal time variable) and noise exposure in regression models.

Results: Of 1347 participants, the mean (SD) baseline age was 63 (14) years, and 772 (57%) were female. The mean (SD) follow-up time was 5.1 (5.7) years. Compared to the no/little noise exposure group, groups with some and high noise exposure had significantly higher baseline thresholds from 2.0 kHz to 8.0 kHz and PTA, and 1.0 kHz to 8.0 kHz and PTA, respectively. Those with high noise exposure (vs no/little) showed higher rates of threshold change per year at 1.0 kHz and 2.0 kHz. Participants with some and high noise exposure showed lower rates of change per year at 3.0 kHz to 8.0 kHz and 4.0 kHz to 8.0 kHz, respectively, where hearing loss had already occurred. The rate of PTA change per year did not differ across noise exposure groups.

Conclusions and relevance: In this cohort study, noise exposure was associated with poorer baseline hearing and higher rates of annual decline at some midfrequencies. Noise exposure can have immediate and potentially long-term negative impacts on hearing.

Importance: Investigating rural-urban and regional differences in the association between dual sensory loss (concurrent hearing and vision loss) and depression may highlight gaps in sensory loss research and health care services, and by socioeconomic status. Whether urbanicity and region may modify associations between sensory loss and depression is unknown.

Objective: To describe the rural-urban and regional differences in the association of dual sensory loss with depression among older adults.

Design, setting, and participants: This cross-sectional study used data from wave 1 (April 2017-December 2019) of the population-based Longitudinal Aging Study in India (LASI). Participants were recruited from 35 states and union territories in India. LASI incorporated a multistage stratified area probability cluster sampling design to recruit participants 45 years and older and their spouses; 31 447 eligible participants 60 years of age or older were interviewed. Data analyses were conducted from May 17, 2022, to November 11, 2023.

Exposures: Sensory loss (no sensory loss, hearing loss only, vision loss only, and dual sensory loss) was determined by respondents' self-reported perceived difficulty regarding hearing and vision function.

Main outcomes and measures: The Composite International Diagnostic Interview (CIDI-SF) scale was used to identify major episodic depression. Logistic regression was used to estimate the odds ratios (ORs) and 95% CIs of depression comparing participants with vs without sensory loss, adjusting for demographic and clinical covariates. Rural-urban and regional differences were assessed by including interaction terms between these variables and sensory loss.

Results: The study analysis included 27 927 participants (mean [SD] age, 68.0 [7.2] years; 14 477 [51%] females and 13 450 [49%] males). The fully adjusted models showed that the odds of depression with dual sensory loss (vs no loss) was higher in urban (OR, 3.16; 95% CI, 2.00-4.99) vs rural (OR, 1.73; 95% CI, 1.31-2.29) residents and among residents in the West (OR, 5.10; 95% CI, 1.74-14.97) vs North (OR, 1.38; 95% CI, 0.81-2.35) regions.

Conclusions and relevance: These findings indicate that sensory loss is associated with depression in older adults, with differences by urbanicity and region. Adults with sensory loss across multiple systems may be an important group to target for intervention.
