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.

Importance: Facial synkinesis refers to pathologic cocontraction and baseline hypertonicity of muscles innervated by the facial nerve, commonly attributed to the aberrant regeneration of nerve fibers following injury. The pathomechanism and optimal treatment of facial synkinesis remain unclear. The goal of this review is to highlight current understanding of the epidemiology, pathophysiology, clinical presentation, assessment, and treatment of facial synkinesis.

Observations: Research into the epidemiology and risk factors of facial synkinesis is limited due to a lack of large databases tracking patients with facial palsy, inherent selection bias, and the wide range of symptom severity. Misguided nerve regeneration, polyneuronal innervation, and cortical changes are implicated in the development of synkinesis, and a better understanding of these mechanisms is required to develop new treatments. The clinical presentation of facial synkinesis varies considerably among patients, and important prognostic questions regarding timing of onset and progression of symptoms remain incompletely answered. Current management options for facial synkinesis include noninvasive modalities, chemodenervation, myectomy, and selective neurectomy. Potential new treatments for facial synkinesis are being investigated in animal models, but few have been tested in humans.

Conclusions and relevance: The treatment of facial synkinesis is currently hindered by limitations in clinical research and understanding of pathomechanism. Current studies predominantly yield level 4 evidence or lower. The development of large datasets of patients with facial palsy and the translation of basic science evidence to humans will facilitate the advancement of new treatments.

Importance: The benefit of adenoidectomy on otologic outcomes after tympanostomy tube (TT) insertion is unclear. Results from prior work are challenging to interpret due to small sample sizes, heterogeneous study designs, and varying outcome measures.

Objective: To evaluate the association between adenoidectomy and otologic outcomes using a US population-level sample of children who received TTs, producing generalizable results for widespread clinical application.

Design, setting, and participants: A matched cohort study was conducted using claims data from the Merative MarketScan Research Databases. The study included 601 848 children who received TTs between January 1, 2007, and December 31, 2021. Children who received adenoidectomy and TTs simultaneously (Ad+TT) were identified irrespective of the number of prior TTs. Control participants who received TTs without adenoidectomy were matched based on sex, age at the time of the procedure, and the number of prior TT procedures.

Exposures: Adenoidectomy without tonsillectomy was the primary exposure.

Main outcomes and measures: The primary outcomes were repeat TT insertion and subsequent oral antibiotic prescriptions after TT insertions. Multivariable logistic regression was used to quantify the effects of adenoidectomy and covariates on each outcome. Stratified analyses were performed in children younger than 4 years and 4 years or older.

Results: Overall, 601 848 children (median [IQR] age, 2 [1-4] years; range, 0-11 years; 351 078 [58.3%] male) who received TTs were identified. The Ad+TT cohort included 201 932 children, with an equal number in the matched cohort. In children younger than 4 years, Ad+TT was common and was associated with lower odds of subsequent oral antibiotics (odds ratio [OR], 0.59; 95% CI, 0.58-0.60) but higher odds of repeat TT insertions (OR, 1.24; 95% CI, 1.22-1.27). In children 4 years or older, Ad+TT was associated with lower odds of repeat TT insertions (OR, 0.78; 95% CI, 0.75-0.81) and subsequent oral antibiotics (OR, 0.63; 95% CI, 0.62-0.65).

Conclusions and relevance: This study found that in children younger than 4 years, Ad+TT was commonly performed and may have had a secondary benefit of reducing subsequent oral antibiotic courses; however, it was not associated with a reduction in the risks of repeat TT insertions. In children 4 years or older, Ad+TT was associated with a reduction in the risk of repeat TT insertions and subsequent oral antibiotics. Given these findings, Ad+TT may be offered in children 4 years or older to improve otologic outcomes.
