Differences in gustatory sensitivity, nutritional habits, circulating levels of modulators, anthropometric measures, and metabolic assays may be involved in overweight (OW) development. The present study aimed at evaluating the differences in these aspects between 39 OW (19 female; mean age = 53.51 ± 11.17), 18 stage I (11 female; mean age = 54.3 ± 13.1 years), and 20 II (10 female; mean age = 54.5 ± 11.9) obesity participants when compared with 60 lean subjects (LS; 29 female; mean age = 54.04 ± 10.27). Participants were evaluated based on taste function scores, nutritional habits, levels of modulators (leptin, insulin, ghrelin, and glucose), and bioelectrical impedance analysis measurements. Significant reductions in total and subtests taste scores were found between LS and stage I and II obesity participants. Significant reductions in total and all subtests taste scores were found between OW and stage II obesity participants. Together with the progressive increase in plasmatic leptin levels, insulin, and serum glucose, decrease in plasmatic ghrelin levels, and changes in anthropometric measures and nutritional habits along with body mass index, these data for the first time demonstrated that taste sensitivity, biochemical regulators, and food habits play a parallel, concurring role along the stages evolving to obesity.

Background: Unilateral vestibular hypofunction (UVH) may lead to modifications on metabolism and body composition. Vestibular rehabilitation (VR) demonstrated its effectiveness in ameliorating balance function and several other daily-living aspects. Objectives: The aim of this study was to evaluate metabolic composition, by means of bioelectrical impedance analysis (BIA) and daily activity, with the use of a wrist-worn movement tracker, in UVH participants before and after VR, and to compare data with a healthy control group (CG) of adults. Methods: 46 UVH and 60 CG participants underwent otoneurological testing, self-report and performance questionnaires, BIA, and wore a device tracking daily movement and energy expenditure for one full day; this was performed before and after VR. Results: UVH participants demonstrated a significant (p = 0.008) increase in muscle mass after VR, and, when compared to CG, no differences were present with respect to visceral fat and muscle mass. UVH adults reported a significant increase in energy expenditure spent in movement (p = 0.008) and during the day (p = 0.009), daily number of strides (p = 0.009) and calories spent in sweeping (p = 0.009) and stairing (p = 0.008). Conclusions: Results from this study show that VR provided an improvement of metabolic function and body composition of people with UVH, possibly by contrasting structural modifications in neural pathways stemming from the vestibular nuclei and connected to autonomous function.

Objective: To evaluate the differences in olfactory sensitivity, nutritional habits, levels of modulators of feeding and smell, bioelectrical impedance analysis (BIA) measures and metabolic assays between two groups of participants with stage I and II obesity and reciprocal relationships between these parameters.Methods: Eighteen participants with stage I (11 female; mean age = 54.3 ± 13.1 years) and 20 participants with stage II (10 female; mean age = 54.5 ± 11.9) obesity underwent a food frequency questionnaire and Sniffin' Sticks® test battery, anthropometric parameters, and BIA measurements as well as metabolic assays (including plasma levels of leptin, insulin, ghrelin, glucose, insulin-like growth factor-1 [IGF-1] and usual laboratory parameters).Results: The stage II obesity participants demonstrated significant higher levels of insulin and leptin and lower levels of ghrelin and IGF-1, a reduction in odor identification (OI) and in total olfactory score, and an increase in visceral and total fat percentage. Among a mosaic of multiple correlations, ghrelin was found to positively correlate with OI and leptin negatively with odor discrimination.Conclusion: The present study expands the notions positing the olfactory perception - and its connections with metabolic cues, foods habits and BIA measures - changes across the two most important obesity stages. This could ameliorate clinical and research deepening of obesity-related olfactory behavior with possible consequences on diagnosis, treatment and prevention of onset and development of obesity, thus opening possible future strategies involving multidisciplinary contributions.Level Of Evidence: 3 Laryngoscope, 132:2028-2035, 2022.

BACKGROUND: Posturography power spectra (PS) implementation has been proven to discriminate between sensory inputs detriment of vestibular and proprioceptive origin. OBJECTIVE: To deepen the role of posturography testing in the diagnostic route of dizzy conditions, by comparing two groups of patients –93 affected by cervicogenic dizziness (CGD) and 72 by unilateral vestibular hypofunction (UVH) –with a group of 98 age- and gender-matched healthy subjects, serving as control group (CON). METHODS: All participants underwent otoneurological testing including video head impulse test (vHIT) and posturography testing with PS analysis. They also filled in Dizziness Handicap Inventory (DHI), Tampa Scale for Kinesiophobia and Hospital Anxiety and Depression Scale questionnaires. RESULTS: UVH and CGD patients were found to have significant increase in vestibular- and proprioceptive-related PS values when compared with CON. Receiver operating characteristic curves found PS values to reliably discriminate both groups from CON. Positive and negative correlations were respectively found between vestibular-/proprioceptive-related PS domain and DHI in both groups and between PS and vHIT scores in UVH patients. CONCLUSIONS: PS analysis demonstrated to be useful in differentiating CGD and UVH patients each other and when compared to CON, to objectively represent perceived symptoms filled along the DHI scale and to corroborate the rate of vestibular deficit in UVH patients.

Objective: To evaluate sleep behavior and its relation to otoneurological parameters in a group of patients with chronic unilateral vestibular hypofunction (UVH) without self‐reported sleep disturbances when compared with healthy subjects serving as a control group (CG). Methods: Fifty‐one patients affected by UVH underwent a retrospective clinical and instrumental otoneurological examination, a 1‐week actigraphy sleep analysis, and a series of self‐report and performance measures (SRM/PM). A CG of 60 gender‐ and age‐matched healthy subjects was also enrolled. A between‐group analysis of variance was performed for each variable, while correlation analysis was performed in UVH patients between otoneurological, SRM/PM, and actigraphy measure scores. Results: When compared with CG subjects, UVH patients were found to be spending less time sleeping and taking more time to go from being fully awake to asleep, based on actigraphy‐based sleep analysis. Also, SRM/PM depicted UVH patients to have poor sleep quality and to be more prone to an evening‐type behavior. Correlations were found between vestibular‐related functionality indexes and subjective sleep quality, as well as between longer disease duration and reduced sleep time. Conclusion: For the first time, a multiparametric sleep analysis was performed on a large population‐based sample of chronic UVH patients. While a different pattern in sleep behavior was found, the cause is still unclear. Further research is needed to expand the extent of knowledge about sleep disruption in vestibular disorders.

To evaluate posturography measurements, and their association with other clinical tests used for cervicogenic dizziness diagnosis, in a cohort of subjects suffering from cervicogenic dizziness, compared with healthy subjects. Ninety-three cervicogenic dizziness patients and 98 age- and gender-matched healthy subjects underwent video-Head impulse test, posturography testing, evaluation of cervical spine movements by means of cervical range of motion goniometer and self-report and performance measures, including Dizziness Handicap Inventory, Neck Disability Index, Neck Pain Intensity, Tampa Scale for Kinesiophobia and Hospital Anxiety and Depression Scale. Cervicogenic dizziness patients demonstrated significant increases in classical posturography parameters (i.e., surface and length) and in power spectra values within middle and high-frequency interval depicting balance control alterations especially due to proprioceptive integration changes. Furthermore, decreases in degrees of cervical range of motion and increases of self-report and performance measures – highlighting significant complaints of subjective feeling of dizziness – were found in these patients when compared with healthy subjects. Multiple correlations were found between posturography testing and cervical range of motion and Dizziness Handicap Inventory as well as between different self-report and performance measures in cervicogenic dizziness patients. The implementation of posturography – including power spectra analysis - coupled with appropriate exclusion of other disorders, may represent a useful tool in improving cervicogenic dizziness assessment in terms of cost, time consumption and correlation with other measurements. Uncertainties in diagnostic assessment of cervicogenic dizziness reflect doubts regarding the causes underpinning the symptoms of imbalance, unsteadiness, and disorientation. Posturography measurement is a low-cost, time-sparing technique and its implementations have proven to be useful in detecting significant alterations in body sway during perturbating situations. Implementation of power spectra analysis on posturography testing may represent a useful tool in improving cervicogenic dizziness assessment also in terms of rehabilitative treatment follow-up.

The aim of this study was to outline an age-dependent range of posturography measures obtained from healthy children. One hundred and fifty healthy 4-18-year-old children underwent video Head Impulse Test and static posturography testing. Surface, length and power spectra values were compared between each group of pupils and 32 healthy adults. As well as a significant (p < 0.025) increase in surface and length, when compared to healthy adults, increased values within the low/middle frequency domain and within the high frequency domain were also observed in 4-13 and 4-7-year-old children, respectively. In conclusion, although the nature of postural control development remains largely undetermined, this study represents a first attempt to outline an age-dependent normal range of the relative contribution of inputs in typically developing children.

The aim of the present scoping review was to evaluate the impact of experimental meal loads or observational diet changes/habits on taste tests in both healthy subjects and patients. A systematic search performed in PubMed, Scopus, and Institute for Scientific Information (ISI) Web of Science electronic databases retrieved, respectively 2981, 6258, and 7555 articles from January 2000 to December 2020. A total of 17 articles were included for full-text review. Literature results were stratified according to the observational/interventional approach, the involvement of healthy subjects or patients, the taste test, and the meal/dietary changes. The present scoping review reinforced the notions postulating that certain taste tests (for example focusing on fatty acid, salt, or sugar) might be specifically influenced by the nutritional intervention and that other ones might be susceptible to a wide span of changes beyond the extent of tastant included in the specific food changes. This could also depend on the inhomogeneity of literature trend: The short duration of the intervention or the random type of meal load, unsuitability of the taste test chosen, and the presence of underlying disorders. Future studies for a better comprehension of taste tests reliability in relation to specific food changes are thus to be fostered. [ABSTRACT FROM AUTHOR]

• Vestibular deficits and cognitive decline share many central pathways. • Degree of cognitive decline may limit vestibular rehabilitation outcomes. • Implementation of head-mounted displays may support vestibular rehabilitation. Due to the gap in the knowledge in the field of vestibular rehabilitation the purpose of this randomized study is to highlight the outcomes of head-mounted display (HMD) implementation in older adults and patients with mild cognitive impairment (MCI), suffering from unilateral vestibular hypofunction (UVH). Vestibulo-ocular reflex (VOR) gain, postural sway examination and dizziness-related and quality of life scores were collected in 12 UVH elderly and 12 UVH subjects suffering from MCI only undergoing vestibular rehabilitation and in 11 UVH elderly and 12 UVH subjects suffering from MCI undergoing a home-based HMD + vestibular rehabilitation protocol. Although the within-subjects analysis found in all groups a significant (p < 0.05) improvement in posturography parameters and dizziness-related and quality of life scores and no changes in VOR gain, implementation of HMD demonstrated a significant (p < 0.05) increase in post-treatment between-group comparisons in the same tests and VOR gain with respect to those older adults and participants with MCI only undergoing vestibular rehabilitation. Positive correlations were discovered between Mini-Mental Score Exam values and pre-/post-treatment differences in (i) power spectra values in the low-frequency interval (r = 0.72) and in (ii) Dynamic Gait Index scores (r = 0.76). This study demonstrates that the implementation of a home-based virtual reality protocol may be a safe option in order to ameliorate VOR, postural control and the quality of life also in the vestibular impaired patients in whom the presence of cognitive decline could hinder the achievement of the goal of rehabilitation.
