BACKGROUND: Although there are articles and studies that associate postural changes with changes in vocal quality, to the best of our knowledge, this was the first study investigating the association between balance disorders and voice. OBJECTIVE: This study aimed to determine whether patients with balance disorders present any clinical, acoustic, or endoscopic vocal changes, and if the correction of balance impairments, such as through vestibular rehabilitation, lead to improvement in vocal quality. METHODS: This was a prospective cohort study that analyzed vocal differences (clinical, videoendostroboscopic, audio-perceptual, and acoustic vocal parameters) in a sample of 43 patients with vestibular dysfunction at three different time points (pre-treatment, post-treatment, and 3 months’ post-treatment) diagnosed by videonystagmography with changes in computerized dynamic posturography who were treated with vestibular rehabilitation. RESULTS: In pre-treatment, all of the patients presented supraglottic hyperfunction during videoendoscopic examination and abnormal values in the audio-perceptual scale. After treatment for balance disorders, there was a statistically significant improvement in some parameters of the videoendoscopic and audio-perceptual measures. These improvements were detected immediately after treatment and remained present until at least three months after treatment. CONCLUSIONS: The results suggested that the treatment for balance disorders results in changes in posture and consequently in voice quality.

Although the pathophysiology of nasal polyposis is incompletely understood, rhinologists have seldom studied it with rhinomanometry or peak nasal inspiratory flow (PNIF) due to technical limitations and the perception that polyp size might impair reproducibility and the usefulness of recordings. The objective of this study is to assess how measures of rhinomanometry and PNIF relate to disease activity. Nineteen patients with polyps, 15 patients with chronic sinusitis without polyps and 11 negative controls were evaluated with active anterior rhinomanometry and PNIF. Sinusitis and polyp patients were re-evaluated after medical treatment. Polyp patients had the highest median Lund-Mackay score (14) and a median Johansen score of 1. PNIF and its variation after treatment were also lowest in this group (median 90 L/min before and after treatment; median variation of 0 L/min). Nasal resistance was similar between groups, and only correlated with Johansen score (Spearman = 0.517, p = 0.048) after treatment. Our study suggests that evaluating polyp patients using rhinomanometry and PNIF may provide useful and reproducible data. Several findings considered together suggest that polyp size is not the main determinant of nasal functional changes in these patients, warranting further studies to verify whether PNIF changes reflect sinus inflammation or merely airway obstruction.

Background: The association between voice and body posture is consensual across the scientific literature and seems to be established both ways. Any changes in normal posture can influence the mechanisms of vocal production; on the other hand, vocal rehabilitation can influence posture. Objectives: This study aimed to evaluate the postural pattern in subjects with organic voice disorders before and after speech rehabilitation, using computerised dynamic posturography (CDP). Methods: In this prospective cohort study, 21 patients affected by dysphonia caused by benign vocal fold lesions, never treated with speech therapy/vocal training, were submitted to a posturographic analysis using CDP before and after vocal rehabilitation/therapy. Each patient underwent an accurate voice and ear, nose, and throat (ENT) anamnesis, a general ENT examination, a rigid and flexible laryngoscopy, a videolaryngostroboscopy, an acoustic voice analysis including aerodynamic evaluation, and a perceptual evaluation of voice using the Grade, Roughness, Breathiness, Asthenia, and Strain (GRBAS) scale and the Voice Handicap Index (VHI) questionnaire, before and after vocal therapy. Fifteen healthy age- and sex-matched volunteers were also submitted to a posturographic analysis on the day of recruitment and 4 weeks later. Results: All patients showed an improvement in voice quality after vocal training. The VHI decreased in all subjects, and the GRBAS scale showed a decrease in all parameters in each vowel (/a/, /i/, /e/) and in spontaneous speech (p < 0.001 for all). Posturographic results showed an improvement in equilibrium score, in conditions 2–6 and composite score. Strategic analysis results showed an improvement in conditions 1–6. Conclusions: The posturographic analysis showed a significant difference in the visual, vestibular, and proprioceptive component of posture after voice therapy. These results showed that dysphonic patients changed their postural patterns after an effective voice treatment, with an improvement in postural performance. It seems like modifications of breathing pattern and voice production techniques led to objective and measurable postural changes.

Background Despite all efforts, the demand for organs increases. New and better strategies are still needed, critical in a crisis like pandemics. Methodology A mathematical approach that integrates need, Opportunity , and Accessibility to kidney transplantation, was created. NOA method, corresponds to the lateral surface area of a trigonal pyramid with the need, Opportunity , and Accessibility as axis, resulting in an intuitional chart output (NOA chart) and a percentage score (NOA score). Higher NOA scores are associated with larger NOA chart areas. Method Application We found some natural variability among the European Member States regarding Need, Opportunity , and Accessibility to kidney transplantation, concomitant with NOA scores. In 2019, in the European Union, 129 patients pmp on the waiting list for a kidney transplant were registered, 47 kidneys pmp were procured, and 36 kidneys pmp were transplanted, corresponding to 25% of kidney transplantation's response capacity. Conclusion Transplantation is frequently the better treatment for end-stage kidney failure. NOA method may be, in the future, an indicator for evaluating the overall transplantation performance regarding the need for it and a tool for policy definition. With NOA method we seek to contribute for: A transplantation overall performance normalizing score; Transplantation response capacity evaluation.

Sjögren's Syndrome (SjS) is a chronic systemic immune-mediated inflammatory disease characterized by lymphocytic infiltration and consequent lesion of exocrine glands. SjS diagnosis and classification remains a challenge, especially at SjS onset, when patients may have milder phenotypes of the disease or uncommon presentations. New biomarkers are needed for the classification of SjS, thus, we aimed to evaluate the added-value of lymphocyte subpopulations in discriminating SjS and non-Sjögren Sicca patients. Lymphocyte subsets from 62 SjS and 63 Sicca patients were characterized by flow cytometry. The 2002 AECG and the 2016 ACR/EULAR SjS classification criteria were compared with clinical diagnosis. The added discriminative ability of joining lymphocytic populations to classification criteria was assessed by the area under the Receiver-Operating-Characteristic Curve (AUC). Considering clinical diagnosis as the gold-standard, we obtained an AUC = 0.952 (95% CI: 0.916–0.989) for AECG and an AUC = 0.921 (95% CI: 0.875–0.966) for ACR/EULAR criteria. Adding Tfh and Bm1 subsets to AECG criteria, performance increased, attaining an AUC = 0.985 (95% CI: 0.968–1.000) (p = 0.021). Th1/Breg-like CD24hiCD27+ and switched-memory B-cells maximized the AUC of ACR/EULAR criteria to 0.953 (95% CI: 0.916–0.990) (p = 0.043). Our exploratory study supports the potential use of lymphocyte subpopulations, such as unswitched memory B cells, to improve the performance of classification criteria, since their discriminative ability increases when specific subsets are added to the criteria.
