ABSTRACT

OBJECTIVE: Age-related cognitive decline involves a complex set of factors. Among these factors, hearing loss is considered to have a significant impact, but the effect of hearing aid use remains unresolved. The purpose of this study was to evaluate the effects of hearing aid use by simultaneously assessing various factors not only cognitive function but also frailty, anxiety, depression, and quality of life (QOL) in patients with hearing loss. METHODS: The cross-sectional study at the Hearing Aid (HA) Center was conducted between 2020 and 2021. Initially, associations with cognitive function, QOL, frailty, and mental state among patients with hearing loss were examined, irrespective of whether they wore a hearing aid or not. Next, these patients were divided into HA users (using HA for more than 1 year) and non-users (no prior use of HA) with 42 patients in each group. The average age and 6-frequency pure tone audiometry (PTA) was 74.5 ± 6.5 years and 50.6 ± 12.1 dB, respectively. All participants filled out the questionnaire about their life style, medical condition. Mini-Mental State Examination (MMSE) for cognitive function, Hospital Anxiety and Depression Scale for mental state, Short Form 36 version 2 (SF-36v2) for QOL, and Kihon Checklist for frailty were compared between HA users and non-users and correlated with the auditory data (PTA and speech discrimination). RESULTS: Among 84 patients, 40 had an MMSE score ≦26. All eight scores and three components of SF-36v2 were lower than those of the control group. The patients with hypertension were significantly more in HA user than in non-HA user, whereas there was no difference in diabetes, heart attack, stroke and education. Although HA users were older and showed hypertension more their PTA was worse than that of non-users, MMSE scores were not different between the groups. MMSE scores correlated with both PTA and speech discrimination in non-users but not in HA users. However, a multivariate analysis of the effect of HA use on MMSE scores adjusting for age, hypertension, and hearing loss, could not be revealed. The vitality and mental component summary of the SF-36v2 was better in HA users than in non-users. CONCLUSION: Elderly patients with hearing loss were cognitively impaired and had low QOL. HA users showed better QOL score than non-HA user, especially about the mental condition. The absence of a correlation between MMSE scores and hearing loss in HA users suggests the potential use of HA in preventing cognitive decline.

ABSTRACT

BACKGROUND: Skeletal muscle metabolism is a major determinant of resting energy expenditure (REE). Although the severe muscle loss that characterizes Duchenne muscular dystrophy (DMD) may alter REE, this has not been extensively investigated. METHODS: We studied REE in 77 patients with DMD ranging in age from 10 to 37 years using a portable indirect calorimeter, together with several clinical parameters (age, height, body weight (BW), body mass index (BMI), vital capacity (VC), creatine kinase, creatinine, albumin, cholinesterase, prealbumin), and assessed their influence on REE. In addition, in 12 patients maintaining a stable body weight, the ratio of energy intake to REE was calculated and defined as an alternative index for the physical activity level (aPAL). RESULTS: REE (kcal/day, mean±SD) in DMD patients was 1123 (10-11 years), 1186±188 (12-14 years), 1146±214 (15-17 years), 1006±136 (18-29 years) and 1023±97 (≥30 years), each of these values being significantly lower than the corresponding control (p<0.0001). VC (p<0.001) was the parameter most strongly associated with REE, followed by BMI (p<0.01) and BW (p<0.05). The calculated aPAL values were 1.61 (10-11 years), 1.19 (12-14 years), 1.16 (15-17 years), and 1.57 (18-29 years). CONCLUSION: The REE in DMD patients was significantly lower than the normal value in every age group, and strongly associated with VC. Both the low REE and PAL values during the early teens, resulting in a low energy requirement, might be related to the obesity that frequently occurs in this age group. In contrast, the high PAL value in the late stage of the disease, possibly due to the presence of respiratory failure, may lead to a high energy requirement, and thus become one of the risk factors for development of malnutrition.

ABSTRACT

We report a case of endolymphatic sac tumor (ELST). A 48-year-old female had recurrent and slowly progressive hearing loss, accompanied with dizziness like Meniere's disease. A tumor was located around the semicircular canals, and was detected on CT and MRI. The patient underwent total removal of the tumor using a transmastoid approach. Histopathological examinations agreed with features of an ELST. The tumor was highly suspected to have originated from the rugose portion of the endolymphatic sac or the endolymphatic duct, based on surgical and imaging studies. Structure of the membranous labyrinth was preserved regardless of the existence of the tumor around semicircular canals with bone destruction. ELSTs seem to have an osteolytic or osteophilic nature, by examining patterns of tumor infiltration.
