Background and Objectives: In this study, we investigated the effects of hearing loss on mental health and quality of life (QoL) using survey data in adults aged >40 years. Subjects and Methods: We obtained data from 10,921 individuals who responded to the fifth Korean National Health and Nutrition Examination Survey. Primary outcomes were measured using questionnaires that recorded stress perception, depressive mood, and suicidal ideation to evaluate mental health and motor ability, self-management, activities of daily living, pain or discomfort, and anxiety or depression to evaluate QoL. Results: On multivariate analysis, suicidal ideation was more prevalent among older adults with hearing loss than in older adults without hearing loss. Motor ability was lower in individuals with hearing loss of >20 dB than in older adults with normal hearing. Categorization of the EuroQol-5 Dimension (EQ-5D) health state into upper and lower groups showed that the EQ-5D values were lower in the moderate-tosevere hearing loss group than in the mild hearing loss group. Conclusions: Among adults aged >40 years, those with hearing loss experienced more suicidal ideation, had lower motor ability, and lower overall QoL compared with these variables in older adults with normal hearing. Additionally, QoL scores were low in individuals with poor hearing. [ABSTRACT FROM AUTHOR]

Objective: To investigate the long‐term educational and occupational status of prelingually bilateral deaf children who received a cochlear implant (CI) before the age of 7, and to identify factors that influence these outcomes. Study Design: Retrospective chart review. Setting: Single tertiary care center. Methods: Seventy‐one children who underwent CI surgery from 2000 to 2007 were included. The latest education and occupation status and word recognition score (WRS) were analyzed. Results: The mean age at the time of surgery and the current age was 3.9 and 22.4 years. The age at CI showed a negative correlation with WRS. All subjects had graduated from high school or obtained an equivalent educational qualification. General high school graduates showed a higher WRS than those who attended a special education high school. The college entrance rate of CI patients (74.6% %) was comparable to that of the general population (72.5%). Subjects who went to college had a significantly better WRS than those who did not (51.4% vs 19.3%). Excluding 30 subjects currently enrolled in college, 26 (62%) of the remaining 41 were currently employed and engaged in various vocational activities, of which most (21 out of 26, 81%) were employed through vocational training institutes, or via special recruitment policy for the disabled. Conclusion: The long‐term use of CI in prelingually deaf children enables not only speech perception but also produces comparable levels of education and employment to those of the general population. A good WRS and supportive policy were related to these successful outcomes. [ABSTRACT FROM AUTHOR]

Background and purpose: Although body weight variability has been associated with mortality, cardiovascular disease, and dementia, the relationship between body weight variability and Parkinson disease (PD) has rarely been studied. We aimed to investigate the longitudinal association between body weight variability and PD incidence. Methods: A nationwide population‐based, cohort study was conducted using the database from the Health Insurance Review and Assessment Service of the whole Korean population. We analyzed 2,815,135 participants (≥40 years old, mean age = 51.7 ± 8.6 years, 66.8% men) without a previous PD diagnosis. We determined individual body weight variability from baseline weight and follow‐up visits. We used Cox proportional hazards regression models. Results: The highest quartile group was associated with increased PD incidence compared with the lowest quartile group after adjustment for confounding factors (hazard ratio [HR] = 1.18, 95% confidence interval [CI] = 1.08–1.29). In contrast, baseline body mass index, baseline waist circumference, and waist circumference variability were not associated with increased PD incidence. In the body weight loss group, individuals within the quartile of the highest variation in body weight showed a higher HR of PD risk than those within other quartiles (HR = 1.41, 95% CI = 1.18–1.68). Conclusions: Body weight variability, especially weight loss, was associated with higher PD incidence. This finding has important implications for clinicians and supports the need for preventative measures and surveillance for PD in individuals with fluctuating body weight. [ABSTRACT FROM AUTHOR]

Objectives/Hypothesis: There may be an interobserver variation in the diagnosis of laryngeal disease based on laryngoscopic images according to clinical experience. Therefore, this study is aimed to perform computer‐assisted diagnosis for common laryngeal diseases using deep learning‐based disease classification models. Study Design: Experimental study with retrospective data Methods: A total of 4106 images (cysts, nodules, polyps, leukoplakia, papillomas, Reinke's edema, granulomas, palsies, and normal cases) were analyzed. After equal distribution of diseases into ninefolds, stratified eightfold cross‐validation was performed for training, validation process and remaining onefold was used as a test dataset. A trained model was applied to test sets, and model performance was assessed for precision (positive predictive value), recall (sensitivity), accuracy, F1 score, precision–recall (PR) curve, and PR‐area under the receiver operating characteristic curve (PR‐AUC). Outcomes were compared to those of visual assessments by four trainees. Results: The trained deep neural networks (DNNs) outperformed trainees' visual assessments in discriminating cysts, granulomas, nodules, normal cases, palsies, papillomas, and polyps according to the PR‐AUC and F1 score. The lowest F1 score and PR‐AUC of DNNs were estimated for Reinke's edema (0.720, 0.800) and nodules (0.730, 0.780) but were comparable to the mean of the two trainees' F1 score with the best performances (0.765 and 0.675, respectively). In discriminating papillomas, the F1 score was much higher for DNNs (0.870) than for trainees (0.685). Overall, DNNs outperformed all trainees (micro‐average PR‐AUC = 0.95; macro‐average PR‐AUC = 0.91). Conclusions: DNN technology could be applied to laryngoscopy to supplement clinical assessment of examiners by providing additional diagnostic clues and having a role as a reference of diagnosis.

This study aims to analyse the volumetric changes in brain MRI after cochlear implantation (CI), focusing on the speech perception in postlingually deaf adults. We conducted a prospective cohort study with 16 patients who had bilateral hearing loss and received unilateral CI. Based on the surgical side, patients were categorized into left and right CI groups. Volumetric T1-weighted brain MRI were obtained before and one year after the surgery. To overcome the artifact caused by the internal device in post-CI scan, image reconstruction method was newly devised and applied using the contralateral hemisphere of the pre-CI MRI data, to run FreeSurfer. We conducted within-subject template estimation for unbiased longitudinal image analysis, based on the linear mixed effect models. When analyzing the contralateral cerebral hemisphere before and after CI, a substantial increase in superior frontal gyrus and superior temporal gyrus (STG) volumes was observed in the left CI group. A positive correlation was observed in the STG and post-CI word recognition score in both groups. As far as we know, this is the first study attempting longitudinal brain volumetry based on post-CI MRI scans. We demonstrate that better auditory performance after CI is associated with structural restoration in central auditory structures., (© 2024. The Author(s).)

Background: Endoscopic ear surgery is a promising technique for removing congenital cholesteatoma in children. It can provide greater visual access to hidden areas of the middle ear and facilitate middle-ear manipulation. This study compares a single-center experience in manag- ing congenital cholesteatoma with an endoscopic approach with that in managing congenital cholesteatoma with a conventional microscopic approach., Methods: Records of consecutive patients aged under 8 with congenital cholesteatoma confined to the middle ear at our tertiary referral hospital from January 2013 to December 2018 were retrospectively reviewed. Operation time, hospital stay, postoperative complications, and recurrence/residue of congenital cholesteatoma were compared between patients receiving microscopic versus endoscopic surgery., Results: A total of 33 pediatric patients aged from 19 months to 7 years were enrolled; 12 children underwent microscopic surgery, and 21 received an endoscopic approach for removing congenital cholesteatoma. The mean operative time was 1.61 hours for the microscopic group and 1.49 hours for the endoscopic group without statistical difference. No postoperative sensorineural hearing loss and complications were reported. Four cases of recurrence/residue were observed on the follow-up endoscopic exam or computed tomography, and no differences were shown between the 2 groups. Of the total patients, 94.7% (n=11) in the microscopic group and 90.5% (n=19) in the endoscopic group demonstrated an intact tympanic membrane without perforation or retraction after surgery. No audiological differences were reported between the 2 groups., Conclusion: Endoscopic ear surgery can effectively and safely remove congenital cholesteatoma in children and is not inferior to conventional microscopic approaches.
