Objective

To analyze the Benefit of Modulated Masking (BMM) on hearing in young, adult and elderly normal-hearing individuals.

Methods

The sample included 60 normal-hearing individuals aged 18–75 years who underwent behavioral assessment (sentence recognition test in the presence of steady and modulated noise) and electrophysiological assessment (cortical Auditory Evoked Potential) to investigate BMM. The results were analyzed comparatively using the paired t-test and ANOVA for repeated measures, followed by the Bonferroni post-hoc test (p-value < 0.05).

Results

A decrease in latencies and an increase in amplitudes of cortical components (P1-N1-P2) was observed due to noise modulation in all age groups. Modulated noise generated better auditory threshold responses (electrophysiological and behavioral), compared to steady noise. The elderly presented a higher threshold in both hearing domains, compared to the other participants, as well as a lower BMM magnitude.

Conclusion

It was possible to conclude that the modulated noise generated less interference in the magnitude of the neural response (smaller latencies) and in the neural processing time (larger amplitudes) for the speech stimulus in all participants. The higher auditory thresholds (electrophysiological and behavioral) and the lower BMM magnitude observed in the elderly group, even in the face of noise modulation, suggest a lower temporal auditory performance in this population, and may indicate a deficit in the temporal resolution capacity, associated with the process of aging.

Objective

Observational studies have shown that Helicobacter pylori is related to some otolaryngological diseases. However, it is unclear if H. pylori infection causally affects these diseases. To elucidate H. pylori role in 12 common otolaryngological diseases, we conducted two-sample Mendelian randomization analysis.

Methods

Single-nucleotide polymorphisms associated with 7 H. pylori antibodies (IgG, CagA, Catalase, GroEL, OMP, UREA and Vac A) served as instrumental variables. We primarily employed random-effects inverse variance weighting for causal estimation, supplemented by MR Egger, weighted median, simple mode, and weighted mode. Sensitivity analyses, including heterogeneity, pleiotropy, and leave-one-out tests, validated robustness.

Results

MR analysis using inverse variance weighting (random effects) revealed genetically predicted H. pylori CagA antibodies correlated with increased risk of nonsuppurative otitis media (OR = 1.0778, 95% CI 1.0114–1.1487, p-value = 0.021). No causal relationship was observed between H. pylori antibodies and other common otolaryngological diseases. Sensitivity analyses found no pleiotropy or heterogeneity, affirming result reliability.

Conclusion

This study suggests that the levels of H. pylori CagA antibodies may contribute to the development of nonsuppurative otitis media. Further studies are needed in the future to elucidate the specific mechanism of H. pylori in this disease.

Objective

To evaluate the ability of the variables Muscle Mass percentage (%MM), Body Fat percentage (%BF), Phase Angle (PhA), and Standardized Phase Angle (SPhA) to predict overall survival rates in individuals with surgically treated HNC.

Methods

A prospective cohort study of surgically treated HNC patients was carried out between 2017 and 2022 at a cancer referral center in Feira de Santana, Bahia. All subjects were seen by an experienced dietitian the week before surgery. During this visit, patients had their sociodemographic and clinical data collected, as well as anthropometric measurements (weight and height) and BIA variables. In this study, postoperative overall 5-year survival was defined as the time in months between the date of surgery and the date of death, regardless of the cause of death. Patients were followed up after surgery until death.

Results

Seventy-eight older adult patients were consecutively included. Patients had a median age of 65.5-years, were mostly men (83.3%), and most had low education levels (62.3%) and low household income, ranging from zero (19.2%) to the minimum wage (60.2%). They were mostly alcohol drinkers (91%) and tobacco smokers (87.2%). Glottic cancer was diagnosed in 48.7% of patients, with 44.8% of cases with stage-IV disease. Forty (51.2%) deaths were recorded in the follow-up period, with a median survival time of 39 months. Variables %MM, %BF, and SPhA were not significantly different between groups (alive vs. dead patients). PhA was considered an independent predictor of overall survival, with an accuracy of 69% (95% CI 0.57‒0.80). When comparing survival curves, patients with a preoperative PhA < 6.8° were more than twice as likely to die during follow-up (HR = 2.38; p =  0.02; 95% CI 1.14‒4.97).

Conclusion

Out of the assessed BIA variables, preoperative PhA was considered a good predictor of overall survival after HNC surgery.

Objective

This study aimed to investigate the potential reduction of cardiovascular stress response caused by suspension laryngoscopic surgery through the application of lidocaine spray on the larynx and trachea.

Methods

A total of 68 patients scheduled for elective suspension laryngoscopic surgery were randomly assigned to either the lidocaine group (Group L, n = 34) or the control group (Group C, n = 33). In Group L, patients received a sprayed lidocaine dose of 2 mg/kg on the larynx and trachea after anesthesia induction, prior to intubation. In Group C, equal volumes of saline solution were administered. MAP and HR were recorded at various time points: before anesthesia (T0), 1-minute after intubation (T1), 1 and 3 min after suspension laryngoscopy (T2 and T3), at the end of the operation (T4), and at 1, 5, and 30 min after extubation (T5, T6, and T7). Arterial blood glucose, epinephrine, and norepinephrine levels were measured at T0, T2, T5, and T7. The occurrence of severe cough and sore throat at T6 and T7 after extubation was compared between the two groups.

Results

At T0 and T1, there were no statistically significant differences in mean arterial pressures, heart rate, and blood catecholamine levels between the two groups. However, from T2 to T7, the blood pressure and heart rate in Group L were lower compared to Group C, with significant differences observed at T2‒T6 (p < 0.05). Group L also showed less elevation in blood glucose at T2, T5, and T7 (p < 0.05). The changes in epinephrine and norepinephrine levels between the two groups were statistically significant at T2 and T5 (p < 0.05).

Conclusions

Administering lidocaine spray on the larynx and trachea during intubation for suspension laryngoscopic surgery can effectively alleviate the stress response.

Objective

To translate and validate the Facial Feminization Surgery Outcomes Evaluation in Brazilian Portuguese.

Methods

A standard back-translation method was applied to obtain the final Brazilian Portuguese language version. In total, 21 Brazilian native Portuguese speakers transgender women with surgical intent and 21 Brazilian native Portuguese speakers transgender women without surgical intent were included in the study. The FFSOE was administered to both groups and all patients underwent a test-retest two weeks later.

Results

The FFSOE showed a high internal consistency with Cronbach’s alpha greater than 0.8. The test-retest reliability was high with repeated measures being highly correlated in all items, except for item 3, where the difference was significant (p =  0.027).

Conclusion

The FFSOE showed reliability, internal consistency and reproducibility in the evaluations. It is easy to understand and quick to apply, making it a simple tool for pre- and post-operative assessment in facial feminization surgeries.

Objective

To investigate the efficacy of cluster nursing intervention based on Enhanced Recovery After Surgery (ERAS) for xerostomia in chronic rhinosinusitis after nasal endoscopic surgery.

Methods

A total of 80 patients with chronic rhinosinusitis who underwent functional nasal endoscopic surgery between January 2020 and December 2021 were selected and randomly divided into a control group (n = 40) and an experimental group (n = 40). Patients in the control group were treated with general nursing, while ERAS-based cluster nursing intervention was adopted for the experimental group, in addition to general nursing. Xerostomia stage and comfort level were observed at 2 h, 6 h, 24 h and 48 h after surgery; negative emotions before and after nursing were also observed.

Results

After the intervention, the xerostomia stage and comfort level at 6, 24 and 48 after surgery were higher in the experimental group (p < 0.05). Negative emotions in the experimental group were lower after nursing (p < 0.001). The self-rating depression scale and self-rating anxiety scale scores increased after nursing in both two groups (p < 0.05).

Conclusion

Enhanced recovery after surgery-based cluster nursing intervention can alleviate xerostomia, improve patients' comfort levels, reduce their negative emotions and accelerate postoperative recovery.

Objectives

Allergic diseases and Meniere's disease found to have a possible link in observational study. However, the potential causal relationship between the two is unclear. Therefore, we aimed to explore the causal relationship between allergic diseases and Meniere's disease using a new data analysis technique called bidirectional Mendelian randomization study.

Method

Summary-level statistics for Meniere's disease and three allergic diseases (asthma, allergic rhinitis, eczema/dermatitis) were obtained from large-scale genome-wide association studies. The inverse variance weighted method was used as the primary measure, supplemented by MR-Egger regression and the weighted median method. To ensure the reliability of the conclusions, Cochran's Q, MR-Egger intercept, MR-PRESSO test, leave-one-out test, and MR Steiger test were used.

Results

Inverse-variance weighted method showed asthma (p = 0.008, OR = 3.908, 95% CI 1.424–10.724, adjust_p = 0.024), allergic rhinitis (p = 0.026, OR = 24.714, 95% CI 1.479–412.827, adjust_p = 0.026) and eczema/dermatitis (p = 0.019, OR = 3725.954, 95% CI 3.795 to 3,658,399.580, adjust_p = 0.029) all had a significant effect on Meniere's disease. Reverse Mendelian randomization studies have shown that Meniere's disease does not increase the risk of three allergic diseases. Sensitivity analysis showed no horizontal pleiotropy and heterogeneity for each trait.

Conclusion

Our Mendelian randomization analysis supports a positive causal relationship between three allergic diseases (asthma, allergic rhinitis, eczema/dermatitis) and Meniere's disease. This suggests that physicians should pay more attention to the Meniere's patient's allergy history and consider allergy avoidance as part of their treatment plan.

Level of evidence

Mendelian Randomized (MR) studies are second only to randomized controlled trials in terms of the level of evidence.

Objective

To report the process of translation and cross-cultural adaptation of theYale Pharyngeal Residue Severity Rating Scale into Brazilian Portuguese.

Methods

Methodological study approved by the Ethics Committee of the Institution (nº 5.166.256). The English original scale was translated into Brazilian Portuguese following suggested in the literature guidelines and recommendations after authorization from the authors of the original instrument, and involved the following reported steps of (1) Translation, (2) Synthesis of translations, (3) Determination of the applicability of the translated version 4) Back-translation, (5) Synthesis of the back-translated versions, and (6) Final synthesis. The translations and back-translations were performed by two bilingual translators. The research committee constituted three specialists who considered whether the linguistic, semantics, conceptual, idiomatic, and contextual equivalence of the translations and back-translations were. In Step 3, the raters consisted of three Speech-Language Pathologists and five ENT physicians divided into two subgroups (less than 5 years of professional expertise, and more than 5 years of professional expertise).

Results

Step 1 was carried out properly by the translators, in Step 2 the translated version was prepared after minor adjustments. In Step 3, the raters reported that they found no difficulties in applying the scale. The Cronbach's Alpha coefficient was 0.995, demonstrating high internal consistency of the instrument, and the analysis of the Intraclass Correlation Coefficient (ICC) among the eight raters was 0.994 with a confidence interval between 0.990 and 0.998, demonstrating excellent agreement, regardless of experience. The research committee judged the last to be adequate and not to require adjustments.

Conclusion

The Brazilian Portuguese version of theYale Pharyngeal Residue Severity Rating Scale is presented in this study.

This is a methodological study – No level of evidence.
