Meta-Analysis
PURPOSE
Background noise and voice problems among teachers can degrade listening conditions in classrooms. The aim of this literature review is to understand how these acoustic degradations affect spoken language processing in 6- to 18-year-old children.
METHOD
In a narrative report and meta-analysis, we systematically review studies that examined the effects of noise and/or impaired voice on children's response accuracy and response time (RT) in listening tasks. We propose the Speech Processing under Acoustic DEgradations (SPADE) framework to classify relevant findings according to three processing dimensions-speech perception, listening comprehension, and auditory working memory-and highlight potential moderators.
RESULTS
Thirty-one studies are included in this systematic review. Our meta-analysis shows that noise can impede children's accuracy in listening tasks across all processing dimensions (Cohen's between -0.67 and -2.65, depending on signal-to-noise ratio) and that impaired voice lowers children's accuracy in listening comprehension tasks ( = -0.35). A handful of studies assessed RT, but results are inconclusive. The impact of noise and impaired voice can be moderated by listener, task, environmental, and exposure factors. The interaction between noise and impaired voice remains underinvestigated.
CONCLUSIONS
Overall, this review suggests that children have more trouble perceiving speech, processing verbal messages, and recalling verbal information when listening to speech in noise or to a speaker with dysphonia. Impoverished speech input could impede pupils' motivation and academic performance at school.

Meta-Analysis Review
Laryngeal ultrasound (US) is becoming widely accepted for assessing true vocal fold immobility (TVFI), a potential complication of laryngeal and thyroid surgery. The objective of this project is to perform a systematic review and meta-analysis of pooled evidence surrounding laryngeal US as a modality for diagnosing TVFI in adults at risk for the condition in comparison to laryngoscopy as a gold standard. Medical subject heading terms were used to search MEDLINE, Embase, Google Scholar, Web of Science, and the Cochrane Library for relevant citations from January 1, 2000, to June 30, 2020. Studies were included if they involved patients 16 years and older, where laryngeal US was compared to laryngoscopy for TVFI. Studies were excluded if there were insufficient data to compute a sensitivity/specificity table after attempting to contact the authors. Case reports, and case series were also excluded. The initial search returned 1357 citations. Of these, 109 were selected for review utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Thirty citations describing 6033 patients were included in the final meta-analysis. A bivariate random effects meta-analysis was performed, revealing a pooled sensitivity for laryngeal US of 0.95 (95% confidence interval [CI] 0.88-0.98), a specificity of 0.99 (95% CI 0.97-0.99), and a diagnostic odds ratio of 1328.2 (95% CI 294.0-5996.5). The area under the curve of the hierarchical summary receiver operating characteristic curve was 0.99 (95% CI 0.98-1.00). Laryngeal US demonstrates high sensitivity and specificity for detecting VFI in the hands of clinicians directly providing care to patients.

Review
PURPOSE
This paper's purpose is to provide a resource for clinicians and researchers of select voice-related patient-reported outcome measures (PROMs) available in the English language.
METHOD
A systematic search for voice-related PROMs was conducted between September 2020 and July 17, 2021. Databases included APA PsychInfo, Nursing and Allied Health Source, MEDLINE via the EBSCO interface, and Science Direct. Reference lists for PROMs-related articles were mined for reference to PROMs protocols.
RESULTS
Thirty voice-related PROMs were identified and categorized as either developed primarily for use in the clinic (n = 12), developed primarily for use in a specific research study (n = 6), or translated into English for publication (n = 12). Twelve PROMs were summarized: Aging Voice Index, Disease Specific Self-Efficacy in Spasmodic Dysphonia, Evaluation of the Ability to Sing Easily, Evaluating Voice Disability - Quality of Life Questionnaire, Glottal Function Index, Linear Analog Scale of Assessment of Voice Quality, Quality of Life in Recurrent Respiratory Papillomatosis, Speech Disability Questionnaire, Trans Woman Voice Questionnaire, Vocal Cord Dysfunction Questionnaire, Vocal Fatigue Index, and the Vocal Tract Discomfort Scale.
CONCLUSION
The PROMs can be categorized into English-language voice-related PROMs developed primarily for clinical use, English-language PROMs developed primarily for research use, and English-language PROMs translated into English. The extent of reliability and validity testing completed varies in the PROMs developed primarily for clinical use. A PROM's psychometric properties as well as the language in which the PROM was tested, should guide clinicians and researchers as they consider which instrument(s) to use.

Review
INTRODUCTION
In recent years, a number of clinical trials have been published comparing transcutaneous electrical nerve stimulation (TENS) and traditional speech therapy treatment of voice and swallowing functions, but results have been conflicting.
OBJECTIVE
Assess the methodological quality of studies and determine whether TENS is an efficient therapeutic strategy for speech therapy treatment of healthy adults or those with dysphonia and/or dysphagia.
METHODS
The databases used were Medical Literature Analysis and Retrieval System Online (MedLine), Biblioteca Virtual em Saúde (BVS), Cochrane Library and Web of Science (ISI Web of Knowledge). The study was conducted between May 2018 and January 2019, in line with Cochrane Handbook guidelines, and included studies on the use of TENS in healthy adults or those with compromised voice and/or swallowing function.
RESULTS
After the search and extraction of studies, the following were identified: TENS + VOICE: 7 articles; TENS + SWALLOWING: 5 articles. The studies exhibited medium quality and are heterogeneous, making it difficult to determine their effectiveness and the parameters to be used in future research. There were no statistically significant differences between the use of TENS alone or associated with another therapeutic technique for voice. For swallowing function, one study proved better results in cases of associated techniques - TENS + traditional therapy.
DISCUSSION
Speech therapy should increase the number of studies published and improve their methodological quality, reassessing methodological criteria. Current clinical practice is not grounded in evidence-based science. CLINICAL MESSAGE: the studies analyzed exhibited medium methodological quality; there are variations in the time, number and periodicity of the therapeutic sessions for TENS; there were no statistically significant differences between the use of TENS alone or associated with another therapeutic technique in voice; there were statistically significant differences between the use of TENS associated with traditional therapeutic in swallowing function.

STUDY DESIGN
Systematic review. Surgical decompression for degenerative cervical myelopathy (DCM) is associated with perioperative complications, including difficulty or discomfort with swallowing (dysphagia) as well as changes in sound production (dysphonia). This systematic review aims to (1) outline how dysphagia and dysphonia are defined in the literature and (2) assess the quality of definitions using a novel 4-point rating system.
METHODS
An electronic database search was conducted for studies that reported on dysphagia, dysphonia or other related complications of DCM surgery. Data extracted included study design, surgical details, as well as definitions and rates of surgical complications. A 4-point rating scale was developed to assess the quality of definitions for each complication.
RESULTS
Our search yielded 2,673 unique citations, 11 of which met eligibility criteria and were summarized in this review. Defined complications included odynophagia (n = 1), dysphagia (n = 11), dysphonia (n = 2), perioperative swelling complications (n = 2), and soft tissue swelling (n = 3). Rates of dysphagia varied substantially (0.0%-50.0%) depending on whether this complication was patient-reported (4.4%); patient-reported using a modified Swallowing Quality of Life questionnaire (43.1%) or the Bazaz criteria (8.8%-50.0%); or diagnosed using an extensive protocol consisting of clinical assessment, a bedside swallowing test, evaluation by a speech and language pathologist and a modified barium swallowing test/fiberoptic endoscopy (42.9%). The reported incidences of dysphonia also ranged significantly from 0.6% to 38.0%.
CONCLUSION
There is substantial variability in reported rates of dysphagia and dysphonia due to differences in data collection methods, diagnostic strategies, and definitions. Consolidation of nomenclature will improve evaluation of the overall safety of surgery.

Meta-Analysis Review
Hyposalivation is a condition represented by a reduced salivary flow and may include symptoms such as mouth dryness (xerostomia), loss of taste, pain, dysphagia, and dysphonia, all of which greatly affect an individual's quality of life.The aim of the present study was to systematically review the effects of low-level light therapy irradiation (photobiomodulation) on salivary gland function in patients with hyposalivation.The main question of the systematic review was: "Does low-level light irradiation therapy of the salivary glands affect salivary flow rate or indicators of salivary function (ion and protein concentrations) in patients with xerostomia or hyposalivation?" The question was based on the PICO (participant, intervention, control, outcome) principle and followed the PRISMA guidelines. Databases were explored and papers published between the years 1997 and 2020 were reviewed for the following Mesh-term keywords and their corresponding entry terms in different combinations: "Low-level light therapy," "Xerostomia," "Saliva," "Salivary glands," "Salivation."The initial sample consisted of 220 articles. Of those, 47 articles were used for full-text analysis and 18 were used for a systematic review, 14 were used in meta-analysis. According to their individual quality, most articles were classified as high quality of evidence according to the GRADE score. Meta-analysis of the evidence observed increase of unstimulated salivary flow 0.51 SMD compared to placebo (95% CI: 0.16-0.86), I = 50%, p = 0.005.The findings of our review revealed evidence of a beneficial effect of photobiomodulation therapy on salivary gland function. The therapy alleviates xerostomia and hyposalivation. However, these effects are reported short term only and did not induce lasting effects of photobiomodulation therapy on patients' quality of life.

Meta-Analysis Review
BACKGROUND
Dysphonia is a disorder characterized by an alteration in the overall quality of the voice which reduces quality of life. Therefore, we assessed the effectiveness of SOVTEs in the management of dysfunctional and organic dysphonia for acoustic, perceptual-auditive, aerodynamic parameters and self-perception of the disease.
METHODS
a systematic review and meta-analysis were conducted. Findings were reported according to the PRISMA statement. Five databases were searched for RCTs and non- or quasi-RCTs. Studies were independently assessed using the Cochrane Risk of bias (RoB) and ROBINS-I tools. Effect sizes (ES) were calculated only at post-treatment. GRADE criteria were used to assess the quality of evidence.
RESULTS
eight articles were included. Studies investigated several SOVTEs, alone or in combination. None of the study was completely judged at low RoB. The quality of evidence resulted very low for each analysis. SOVTEs revealed to be statistically more effective than control interventions in improving F0 (ES: -14.42; CI 95%: -27.16, -1.69); P = 0.03), whereas shimmer did not change significantly (ES: -0.43; CI 95%:-02.02, 1.15; P = 0.59). Not significant changes in favor of control groups were found for jitter (ES: 0.13; CI 95%: -0.14, 0.40; P = 0.34) and overall gravity in the perceptual-auditory evaluation (ES: 0.13 CI 95%: -0.50, 0.77; P = 0. 68). Among secondary outcomes, evidence suggested that SOVTEs are more effective than control interventions in Psub reduction (ES: -1.47; CI 95%: -2.84, -0.10; P = 0.03); self-assessment resulted not significantly in favor of SOVTEs (VHI/VRQoL: ES -0.23; CI 95% -1.14, 0.69; P = 0.63 and VTDS/VDSI: ES -4.85, CI 95% -25.13, 15.42; P = 0.64).
CONCLUSION
results obtained showed that voice therapy based on SOVTEs is not to consider significantly superior if compared to other treatments, even if a favorable trend was detected and should be taken into consideration. Further high-quality RCTs on specific SOVTEs are recommended to produce better-quality evidence.

UNLABELLED
Benign vocal fold lesions cause dysphonia by preventing vocal fold closure, causing irregular vibration and increasing compensatory muscle tension. Voice therapy delivered in addition to phonosurgery may improve voice and quality of life outcomes but the evidence base is lacking and what constitutes voice therapy for this population is not defined. The purpose of this systematic review is to critically evaluate the evidence for pre and post-operative voice therapy to inform the development of an evidence based intervention.
STUDY DESIGN
Systematic Review.
METHODS
Electronic databases were searched using key terms including dysphonia, phonosurgery, voice therapy and outcomes. Eligible articles were extracted and reviewed by the authors for risk of bias and for information regarding the content, timing and intensity of any pre and post-operative voice therapy intervention.
RESULTS
Of the 432 articles identified, 35 met the inclusion criteria and were included in the review. 5 were RCTs, 2 were individual cohort studies, 1 was a case control study and 26 were case series. There was considerable heterogeneity in participant characteristics. Information was frequently lacking regarding the content timing and intensity of the reported voice therapy intervention, and where present, interventions were highly variable.
CONCLUSION
Reporting in relevant literature is limited in all aspects of content, timing and intensity of intervention. Further intervention development work is required to develop a robust voice therapy treatment intervention for this population, before effectiveness work can commence.

Review
Inhaled corticosteroids (ICSs) are indicated for the prevention of exacerbations in COPD; however, a significant proportion of patients at low risk of exacerbations are treated with ICSs. We conducted a systematic review including a diversity of types of study designs and safety outcomes with the objective of describing the risk of adverse effects associated with the long-term use of ICSs in patients with COPD.A total of 90 references corresponding to 83 studies were included, including 26 randomised clinical trials (RCTs), 33 cohort studies, and 24 nested case-control (NCC) studies. Analysis of 19 RCTs showed that exposure to ICSs for ≥1 year increased the risk of pneumonia by 41% (risk ratio 1.41, 95% CI 1.23-1.61). Additionally, cohort and NCC studies showed an association between ICSs and risk of tuberculosis and mycobacterial disease. There was a strong association between ICS use and local disorders such as oral candidiasis and dysphonia. The association between ICSs and the risk of diabetes and fractures was less clear and appeared significant only at high doses of ICSs.Since most patients with COPD are elderly and with frequent comorbidities, an adequate risk-benefit balance is crucial for the indication of ICSs.

Review
INTRODUCTION
Hyperkinetic dysarthria is characterized by atypical involuntary movements within the speech mechanism that may affect the respiratory, laryngeal, pharyngeal-oral, or velopharyngeal-nasal subsystems and may alter speech production. Although articulatory impairments are commonly considered in hyperkinetic dysarthria, speakers with hyperkinetic dysarthria may also present with changes in voice quality, pitch, and loudness. In approximately 70% of speakers with hyperkinetic dysarthria, these voice alterations are associated with tremor or dystonia. The purpose of this systematic review was to investigate the association between behavioral therapy for tremor or dystonia affecting voice in speakers with hyperkinetic dysarthria and improvement in the functional, perceptual, acoustical, aerodynamic, or endoscopic characteristics of voice.
METHOD
MEDLINE (PubMed), Embase, PsycINFO, and ClinicalTrials.gov online databases were searched in August 2017, December 2018, and April 2020 for relevant studies. The searches provided 4,921 unique records, and six additional unique records were added from other sources. Twelve studies met the criteria for inclusion in the systematic review. Participants who received concurrent medical treatment were included in this review to ensure that the search was inclusive of all relevant studies and informative for typical clinical scenarios.
RESULTS
The most commonly administered treatment ingredient was relaxation training, which was investigated in three of the four studies on tremor and three of the eight studies on dystonia. Of these six studies, only one used an experimental design and administered relaxation training as the only behavioral approach. This single-case experiment reported a significant reduction in participant ratings of tremor severity and interference with activities of daily living, although the speaking subscale reportedly did not improve and oral medications were administered concurrently. In two group studies that tested potential behavioral therapy targets, production of a low pitch improved acoustical measures for participants with essential tremor and improved auditory-perceptual judgments for participants with laryngeal dystonia. Behavioral therapy improved functional, acoustical, and aerodynamic outcomes in participants with laryngeal dystonia who were also receiving botulinum toxin injections in a randomized cross-over study and a non-randomized controlled study. Because one study employed easy onset and breathing exercises, while the other employed loud voice exercises, the mechanism of action for improvement in voice associated with behavioral therapy requires further investigation.
CONCLUSION
This systematic review describes the current evidence for treatment of tremor and dystonia affecting voice in speakers with hyperkinetic dysarthria and highlights the need for future research on behavioral therapy for these disorders.
