Developing and Testing a Smartphone Application to Enhance Adherence to Voice Therapy: A Pilot Study

The present study aimed to develop a smartphone application (app) that addressed identified barriers to success in voice therapy; accessibility, and poor adherence to home practice. The study objectives were (1) to investigate if app use enhanced adherence to the home practice of voice therapy and (2) to test app usability. Maximizing the effectiveness of voice therapy is vital as voice disorders are detrimental to personal and professional quality of life. A single-blinded randomized clinical trial was completed for the first objective. Participants included normophonic individuals randomly assigned to the app group or the traditional group. The primary outcome measure was adherence measured as the number of missed home practice tasks. The second objective was completed through usability testing and a focus group discussion. The app group (n = 12) missed approximately 50% less home practice tasks as compared to the traditional group (n = 13) and these results were statistically significant (p = 0.04). Dropout rates were comparable between the two groups. Usability results were positive for good usability with high perceived usefulness and perceived ease of use. App use resulted in improved adherence to home practice tasks. App usability results were positive, and participants provided specific areas of improvement which are achievable. Areas for improvement include app engagement and willingness to pay.

Dysphagic disorder in a cohort of COVID-19 patients: Evaluation and evolution

Background

COVID-19 is a multisystem disease complicated by respiratory failure requiring sustanined mechanical ventilation (MV). Prolongued oro-tracheal intubation is associated to an increased risk of dysphagia and bronchial aspiration. Purpose of this study was to investigate swallowing disorders in critically ill COVID-19 patients.

Material and methods

This was a retrospective study analysing a consecutive cohort of COVID-19 patients admitted to the Intensive Care Unit (ICU) of our hospital. Data concerning dysphagia were collected according to the Gugging Swallowing Screen (GUSS) and related to demographic characteristics, clinical data, ICU Length-Of-Stay (LOS) and MV parameters.

Results

From March 2 to April 30, 2020, 31 consecutive critically ill COVID-19 patients admitted to ICU were evaluated by speech and language therapists (SLT). Twenty-five of them were on MV (61% through endotracheal tube and 19% through tracheostomy); median MV length was 11 days. Seventeen (54.8%) patients presented dysphagia; a correlation was found between first GUSS severity stratification and MV days (p < 0.001), ICU LOS (p < 0.001), age (p = 0.03) and tracheostomy (p = 0.042). No other correlations were found. At 16 days, 90% of patients had fully recovered; a significant improvement was registered especially during the first week (p < 0.001).

Conclusion

Compared to non-COVID-19 patiens, a higher rate of dysphagia was reported in COVID-19 patients, with a more rapid and complete recovery. A systematic early SLT evaluation of COVID-19 patients on MV may thus be useful to prevent dysphagia-related complications.

Multimodal Evaluation of Voice Outcome in Early Glottic Cancers Treated With Definitive Radiotherapy

BACKGROUND/AIM

We employed a multimodal evaluation of voice outcome (MEVO) model to assess long-term voice outcome in early glottic cancer (EGC) patients treated with primary radiotherapy (RT). The model consisted of objective and subjective vocal evaluation during follow-up, by a dedicated Speech Pathologist and Speech Therapist.

PATIENTS AND METHODS

MEVO methodology includes Self-perception Voice Handicap Index (VHI-30), evaluation of parameters Grade (G), Roughness (R), Breathiness (B), Asthenia (A) and Strain (S) according to GRBAS scale, objective analysis and aerodynamics using the PRAAT software and laryngeal evaluation with videostroboscope (VS).

RESULTS

The MEVO methodology was described and tested on a sample of 10 EGCs submitted to definitive RT (total dose 66-70 Gy). Mean follow-up was 48.9 months (range=9-115). VHI was mild-moderate in 90% of patients; overall voice function (GRBAS) was normal-mildly impaired in 70% of patients; VS evaluation showed normal vocal cord motion in 90% of patients, but complete glottic closure in 60%. PRAAT scores confirmed these findings.

CONCLUSION

A multidimensional voice evaluation is time consuming, but useful to objectify vocal impact of radiotherapy. The MEVO model allowed to quantify vocal dysfunction, showing a good objective vocal outcome.

Clinical analysis of EBRT vs TLM in the treatment of early (T1-T2N0) glottic laryngeal cancer

Objective: To analyze the clinical efficacy of external beam radiation therapy (EBRT) vs transoral laser microsurgery (TLM) in patients with early glottic laryngeal carcinoma (T1-T2N0) and the effect of treatment choice on vocal function.

Methods: A retrospective analysis of patients with T1-T2N0 glottic laryngeal carcinoma who underwent EBRT or TLM between January 2012 and December 2018 in PUMCH. The Kaplan-Meier method was used to analyze local control, progression-free survival and overall survival, and the VHI-30 scale was used to evaluate the effects of EBRT and TLM on vocal function.

Results: A total of 185 patients, all with pathologically confirmed squamous cell carcinoma, were enrolled. The median age was 62 years (38-88). N0 disease was confirmed by imaging: 142/185 (76.76%) patients had T1N0 disease, and 43/185 patients (23.24%) had T2/N0 disease. A total of 91/195 (49.19%) patients received an EBRT dose of 66-70 Gy/30-35f, at 2.0-2.3 Gy/f. 94/185 (50.81%) patients received TLM. The median follow-up time was 42 months (12-92), and the 3-year LC, PFS, and OS rates for the EBRT and TLM groups were 96.9% vs 94.1%(p=0.750), 95.3% vs 93.1%(p=0.993) and 93.3% vs 95.4%(p=0.467), respectively. The VHI-30 scales were used at the baseline showed no significant difference between the two groups 19.20±3.324 vs 21.65±9.80 (p=0.250), but the EBRT group had a low voice handicap after treatment, 10.24±6.093 vs 19.45±5.112 (p=0.001) (6 months) and 9.45±5.112 vs 14.97±7.741 (12 months). No CTCAE grade 3 or above side effects were observed in the EBRT group, but 3 cases of vocal cord stenosis were observed in the TLM group.

Conclusion: The application of EBRT for early glottic laryngeal carcinoma (T1-T2N0) had an obvious curative effect with high LC and OS rates, no serious side effects, and a low voice handicap rate.

Efficacy of Voice Therapy in Improving Vocal Function in Adults Irradiated for Laryngeal Cancers: A Pilot Study

BACKGROUND

Radiation therapy (XRT) for laryngeal cancers causes acute and chronic vocal dysfunction. Although these deleterious effects of XRT are well-established, there is a dearth of research with respect to effective voice rehabilitation following XRT for laryngeal cancers.

OBJECTIVE

To obtain preliminary data on the efficacy of voice rehabilitation, using vocal function exercises (VFEs) in improving vocal function in adults irradiated for laryngeal cancer. The comparison treatment group (VH) received vocal hygiene counseling.

STUDY DESIGN

Randomized clinical trial.

METHODS

Participants were randomized to the VFE + VH or VH group. Both interventions lasted 6 weeks. The primary outcome measure was improvement in VHI scores. Secondary outcome measures included auditory-perceptual assessments, acoustic and aerodynamic measures, and laryngeal imaging.

RESULTS

Ten participants were recruited for the study. The VFE + VH (n = 6) group demonstrated a statistically significant improvement in the primary outcome measure (P = 0.03), as well as select parameters of all secondary outcome measures. The VH (n = 4) group did not demonstrate a statistically significant improvement in primary or secondary outcome measures.

CONCLUSIONS

This study offers preliminary data for the utility of VFEs in the irradiated laryngeal cancer population. However, findings in the VFE + VH group lack generalizability, secondary to sample heterogeneity, and limited sample size.

Voice rehabilitation for laryngeal cancer after radiotherapy: a systematic review and meta-analysis

PURPOSE

We aimed to determine whether voice rehabilitation after radiotherapy improves the quality of life (QOL), voice function, and self-rated voice function in patients with laryngeal cancer.

METHODS

We searched CENTRAL, MEDLINE, EMBASE, PEDro, and World Health Organization International Clinical Trials Registry Platform for randomized controlled trials published between inception and October 2018. The primary outcome was QOL, adverse events and mortality. Secondary outcomes included voice function and self-rated voice function. The quality of evidence was determined using the Grading of Recommendations Assessment, Development, and Evaluation approach.

RESULTS

Three trials (enrolling 122 patients) compared voice rehabilitation to usual care or no intervention after radiotherapy. Voice rehabilitation did not significantly improve any QOL scores. Data on adverse events and mortality were not available in any of the trials. Voice rehabilitation did not improve any voice function scores, such as jitter (mean difference: - 0.48 [- 1.27 to 0.32]), shimmer (mean difference: - 0.04 [- 0.27 to 0.19]), maximum phonation time (mean difference: 1.54 [- 1.13 to 4.22]), and the grade, roughness, breathiness, asthenia, and strain scale (mean difference: - 0.39 [- 2.59 to 1.80]). Voice rehabilitation also did not improve the voice handicap index, which was used as a self-rated voice function score (mean difference: 5.54 [- 2.07 to 13.16]). The certainty of the evidence was graded as low for primary and secondary outcomes.

CONCLUSION

Voice rehabilitation for patients with laryngeal cancer after radiotherapy might not improve QOL, voice function, and self-rated voice function. Pre-specified voice rehabilitation programs may not be necessary for all patients with laryngeal cancer after radiotherapy.

Oral health related quality of life and determinant factors in patients with head and neck cancer

Background

The present study aimed to measure the impact of oral health on the quality of life of patients with head and neck cancer.

Material and Methods

A cross-sectional study was conducted with 130 patients diagnosed with head and neck cancer at two medical centers. Participants answered a sociodemographic questionnaire and the Oral Health Impact Profile - 14 (OHIP-14). Clinical aspects, cancer staging, and treatment approach were also investigated. Mann-Whitney and Kruskal-Wallis non-parametric tests were used for statistical analysis, followed by Poisson regression analysis (with robust error variance), to associate the OHIP-14 scores with independent variables.

Results

The OHIP-14 presented good internal consistency (Cronbach’s Alpha = 0.861). The mean score obtained was 19.52 (±11.79). Physical pain (3.70±2.44), physical disability (3.26±2.62) and functional limitation (3.24±2.45) were ranked as the main factors affecting the quality of life. Patients non-Caucasians (PR = 1.30; IC 95% = 1.07-1.58; p = 0.009), widowers (PR = 1.36; IC 95% = 1.13-1.64; p = 0.001), diagnosed with squamous cell carcinoma (PR = 1.28; IC 95% = 1.05-1.58; p = 0.017) and with temporomandibular pain (PR = 1.31; IC 95% = 1.08-1.60; p = 0.007) were more likely to exhibit lower rates of quality of life.

Conclusions

The results showed a high impact of the oral health in the quality of life of patients with head and neck cancer was observed. Sociodemographic and clinical characteristics can exert influence on the quality of life of patients with head and neck cancer.

Voice Quality in Laryngeal Cancer Patients: A Randomized Controlled Study of the Effect of Voice Rehabilitation

OBJECTIVES

The study aimed to investigate the short-term and long-term effects of voice rehabilitation in patients treated with radiotherapy for laryngeal cancer as measured by both the acoustic measure smoothed cepstral peak prominence (CPPS) and perceptual measures. A secondary aim was to investigate the relationship between acoustic and perceptual measures.

METHODS

In total, 37 patients received voice rehabilitation post-radiotherapy and 37 patients constituted the irradiated control group. Outcome measures were mean CPPS for connected speech and ratings with the auditory-perceptual Grade, Roughness, Breathiness, Asthenia and Strain (GRBAS) scale. Outcome measures were analyzed 1 (baseline), 6, 12, and 24 months post-radiotherapy, where voice rehabilitation was conducted between the first two time-points. Additional recordings were acquired from vocally healthy participants for comparison.

RESULTS

CPPS values of the voice rehabilitation group and vocally healthy group were not significantly different at 24 months post-radiotherapy. Ten out of 19 patients who received voice rehabilitation yielded a CPPS value above the threshold for normal voice 24 months post-radiotherapy, compared to 11 out of 26 in the irradiated control group. No statistically significant correlations were found between CPPS and perceptual parameters of GRBAS.

CONCLUSION

Voice rehabilitation for irradiated laryngeal cancer patients may have positive effects on voice quality up to 24 months post-radiotherapy. The relationship between CPPS and GRBAS as well as the applicability of CPPS for evaluation over several points of measurement needs to be studied further.

Vocal activity profile and dysphonia coping strategies in subjects with laryngeal cancer treated with radiotherapy

ABSTRACT Purpose: to verify the vocal activity participation and the dysphonia coping strategies of subjects with laryngeal cancer treated with radiotherapy. Methods: a cross-sectional trial involving 17 individuals with laryngeal cancer treated only by radiotherapy with vocal complaints after radiotherapy management. A sociodemographic questionnaire, the Brazilian versions of Voice Activity and Participation Profile and Voice Disability Coping Questionnaire protocols were applied. Results: there was a prevalence of male participants (n=16) and the mean age was 62 years. All were former smokers and 15 were former drinkers. Voice Activity and Participation Profile in mean scores was: overall,141.2, self-perception of vocal problem, 6.2, effect at work, 19.1, effects on daily communication, 60.5, effects on media, 20.1, and effects on their emotional, 36.7. In Voice Disability Coping Questionnaire mean scores were: overall,71.7, focusing on problem, 33, and focusing on emotion, 38.9. Conclusion: the participants had high Voice Activity and Participation Profile scores as compared to the literature scores considered for dysphonic individuals in general, and activity with effects on daily communication was the most affected. Voice Disability Coping Questionnaire demonstrates that these patients adopt dysphonia coping strategies with greater focus on emotion.
