Hearing thresholds at conventional and extended high frequencies in young personal listening devices' users: A pilot study.

<b>Introduction:</b> The exposure to unsafe sound levels is considered a risk factor for developing noise-induced hearing loss (NIHL). Personal listening devices (PLDs) represent a common source of recreational noise among young adults. First changes of NIHL could be detected at extended high frequencies (EHFs).

Assessment of sensory impairment in older adults with dementia.

Background: Over 55 million people worldwide are living with dementia. The rate of cognitive decline increases with age, and loss of senses may be a contributing factor.

Objectives: This study aimed to analyze hearing, olfactory function, and color vision in patients with dementia.

Extended High-frequency Audiometry in the Elderly: A Narrative Review.

Extended high-frequency audiometry (HFA) is considered an important tool in the detection of hearing loss. However, the values at extended high frequencies (EHF) in older adults (in both men and women) are associated with considerable uncertainty due to limited reference data. The presented review aimed to analyze hearing thresholds at EHF in adults older than 60 years.

The comparison between intratympanic gentamicin prehabilitation and postoperative virtual reality exposure to standard vestibular training in patients with vestibular schwannoma.

Objective: Resection of the vestibular schwannoma causes acute peripheral vestibular loss. The process of central compensation starts immediately afterward. The rehabilitation goal is to support this process and restore the quality of life.

The relationship between atherosclerosis and dementia.

Objective: The main objective is to confirm a hypothesis that atherosclerosis, through various mechanisms, considerably influences cognitive impairment and significantly increases the risk for developing dementia. Complete sample should be 920 individuals. The present study aimed to analyse epidemiological data from a questionnaire survey.

Cognitive impairment, neurodegenerative disorders, and olfactory impairment: A literature review.

Does vestibular function correlate with objective MRI findings after vestibular schwannoma surgery?

Objective: Vestibular schwannoma surgery leads to acute unilateral vestibular loss. In some patients, however, the process of post-operatively initiated central compensation proceeds more rapidly than in others. This study aimed to evaluate post-operative vestibular function and correlate it with morphological findings of MRI scans.

Receiver Operating Characteristic Curve Analysis of the Somatosensory Organization Test, Berg Balance Scale, and Fall Efficacy Scale-International for Predicting Falls in Discharged Stroke Patients.

Background: Although fall prevention in patients after stroke is crucial, the clinical validity of fall risk assessment tools is underresearched in this population. The study aim was to determine the cut-off scores and clinical validity of the Sensory Organization Test (SOT), the Berg Balance Scale (BBS), and the Fall Efficacy Scale-International (FES-I) in patients after stroke.

Methods: In this prospective cross-sectional study, we analyzed data for patients admitted to a rehabilitation unit after stroke from 2018 through 2021.

Influence of Rehabilitation Aid with Biofeedback on the Rehabilitation Process during Remote Home-Based Rehabilitation.

Ensuring the regularity and correctness of rehabilitation exercises in the home environment is a prerequisite for successful treatment. This clinical study compares balance therapy in the home environment on a conventional balance mat and an instrumented wobble board, with biofeedback supported by a rehabilitation scheme realized as web-based software that controls the course of rehabilitation remotely. The study included 55 patients with knee injuries.

The Importance of Screening for Hearing Loss in the Elderly.

<b>Aim:</b> The aim was to compare hearing loss between men and women over 65 in pure tone audiometry and to evaluate the sensitivity of the abbreviated version of the Hearing Handicap Inventory (HHIE-S). This questionnaire highlights hearing handicaps in understanding speech. </br></br><b> Materials and Methods:</b> The data was collected in the years 2011-2015 from respondents above 18 years of age using a standar-dized HHIE-S questionnaire and specialized tests.

High-Frequency Audiometry in Women with and without Exposure to Workplace Noise.

For this study, high-frequency audiometry was used to compare the hearing thresholds, with respect to age, among women exposed to noise in their working environment, as well as those not exposed to such noise. The cohort comprised 243 women (average age 36.2 years), of which 88 women were employed in a noisy (L 85-105 dB) workplace, while 155 women did not experience noise.

Residual vestibular function after vestibular schwannoma surgery.

Objectives: This study aimed to assess vestibular function in 39 patients who underwent neurectomy for vestibular schwannoma.

Method: Semicircular canal reactivity was measured by video head-impulse test using high-frequency passive head acceleration. Response gain was calculated as a ratio between the areas under the eye-velocity curve and the head-velocity curve.

Comparing results from vestibular caloric stimulation and vHIT from a specialised outpatient clinic.

Background: Until recently, vestibular caloric stimulation was the only objective diagnostic method for isolating the function of the lateral semi-circular canals responsible for maintaining balance. Since 2014, the Video Head Impulse Test (vHIT) has been applied in the Czech Republic to investigate the function of all semi-circular canals. Studies conducted so far have shown that the results of these two methods do not often agree.

A study evaluating noise levels at selected schools in the Czech Republic.

Objective: Worldwide, primary schools are the most important segment of childhood education. The main disturbing source of noise in schools is human speech, the primary component of the learning process. School noise has a negative impact on information processing, teachers and pupils, and communication in the classroom.

Fatal delayed hemopericardium and hemothorax following blunt chest trauma.

Cardiac injury following blunt chest trauma is common in motor vehicle accidents due to a crush or blast injury. Severe cardiac trauma is associated with a very high mortality. If a cardiac injury develops several weeks after non-penetrating chest trauma, establishing a causal link between the traumatic event and the cardiac injury becomes complicated.

Genetic Aetiology of Nonsyndromic Hearing Loss in Moravia-Silesia.

Hydration-induced changes of structure and vibrational frequencies of methylphosphocholine studied as a model of biomembrane lipids.

The chemical characteristics of the polar parts of phospholipids as the main components of biological membranes were investigated by using infrared (IR) spectroscopy and theoretical calculations with water as a probe molecule. The logical key molecule used in this study is methylphosphocholine (MePC) as it is not only a representative model for a polar lipid headgroup but itself has biological significance. Isolated MePC forms a compact (folded) structure which is essentially stabilized by two intramolecular C-H.

Lipid hydration: headgroup CH moieties are involved in water binding.

To explore the interaction potential of phospholipids, we have studied the hydration of diacyl phosphatidylcholine (PC) and methylphosphocholine (MePC), a pertinent model compound, by ir spectroscopy. Related ab initio Hartree-Fock calculations were performed for MePC. Water is considered ideal as a relevant probe molecule.
