Biomechanical and biochemical properties of the thoracic aorta in warmblood horses, Friesian horses, and Friesians with aortic rupture
Background: Thoracic aortic rupture and aortopulmonary fistulation are rare conditions in horses. It mainly affects Friesian horses. Intrinsic differences in biomechanical properties of the aortic wall might predispose this breed. The biomechanical and biochemical properties of the thoracic aorta were characterized in warmblood horses, unaffected Friesian horses and Friesians with aortic rupture in an attempt to unravel the underlying pathogenesis of aortic rupture in Friesian horses. Samples of the thoracic aorta at the ligamentum arteriosum (LA), mid thoracic aorta (T1) and distal thoracic aorta (T2) were obtained from Friesian horses with aortic rupture (A), nonaffected Friesian (NA) and warmblood horses (WB). The biomechanical properties of these samples were determined using uniaxial tensile and rupture assays. The percentages of collagen and elastin (mg/mg dry weight) were quantified.
Results: Data revealed no significant biomechanical nor biochemical differences among the different groups of horses. The distal thoracic aorta displayed an increased stiffness associated with a higher collagen percentage in this area and a higher load-bearing capacity compared to the more proximal segments.
Conclusions: Our findings match reported findings in other animal species. Study results did not provide evidence that the predisposition of the Friesian horse breed for aortic rupture can be attributed to altered biomechanical properties of the aortic wall
Vocal characteristics of middle-aged premenopausal women
Aging influences the laryngeal anatomy and physiology, leading to altered vocal quality. In middle-aged women, the voice is affected by a combination of aging and menopausal transition. However, in many studies about vocal aging, the menopausal transition is not taken into account. The purpose of this study was to measure and describe the effect of aging on the vocal characteristics by comparing young women (between 20 and 28 years) and middle-aged premenopausal women (between 45 and 52 years). To determine the vocal characteristics in both groups, objective (aerodynamic measurements, vocal performance measurements, acoustic analysis, and a determination of the Dysphonia Severity Index) and subjective assessment techniques (perceptual evaluation, videostroboscopic evaluation, and Voice Handicap Index) were used. The middle-aged premenopausal women showed a smaller frequency and intensity range, a lower habitual fundamental frequency, and a higher soft phonation index compared with the young women. The results of this study are important when studying the voices of middle-aged women. Vocal characteristics of middle-aged women differ from young women, and these changes cannot only be because of hormonal changes during the menopause
Corrigendum on: White paper on European patient needs and suggestions on chronic type 2 inflammation of airways and skin by EUFOREA
Background: Type 2 inflammation underlies the chronicity of disease in subgroups of patients with asthma, chronic rhinosinusitis with nasal polyps (CRSwNP) and atopic dermatitis (AD), that often co-exist. Although several studies have investigated the unmet needs of asthma, AD and CRSwNP as such, little is known about the similarities and differences in experiences and perspectives of the current management of patients with comorbid Type 2 inflammatory diseases.
Aims: To improve insight into the common and organ-specific needs of patients with Type 2 inflammation and comorbidities, allowing the formulation of recommendations to better address these needs in the future.
Methodology: This qualitative study was conducted between July 2021 and December 2021 using semi-structured face-to-face or telephone interviews with patients suffering from year-long severe chronic Type 2 inflammation and at least one co-morbid inflammatory condition. Seven participating academic centers in Europe interviewed asthma (Copenhagen and Leuven), CRSwNP (London, Amsterdam and Crete) and/or AD (Oldenburg and Zurich) patients on patient characteristics, disease severity, shortcomings of current care pathways and suggestions for improvement of care. Transcripts were analyzed using an inductive thematic analysis approach.
Results: Eighty-one patients with severe Type 2 inflammation and comorbidities were interviewed. Similar needs were recognized by patients with Type 2 inflammation, with both a lack of coordination in care and a lack of a real cure reported as being most frustrating. However, several needs are specific to asthma, CRSwNP and AD. Suggestions for improvement of care were generic across diseases, such as the implementation of a multidisciplinary approach, the improved facilitation of access to better treatments, the increase of general awareness on disease burden, and better educational programs for healthcare providers and patients. Of note, patients with CRSwNP also stated the need for alternatives to sinus surgery, whereas patients with asthma requested better medical care to prevent exacerbations and patients with AD would warmly welcome the reimbursement of emollients.
Conclusion: Patients with asthma, CRSwNP and AD have shared unmet needs that need to be addressed by physicians, the academic community and health policy makers. This survey provides unique recommendations made by patients for the implementation of better care

The impact of hormone therapy on vocal quality in postmenopausal women
Objectives : The main purpose of this study was to investigate the impact of hormone therapy (HT) on vocal characteristics in postmenopausal women by comparing postmenopausal women with HT (n = 59) and postmenopausal women without HT (n = 46). The second purpose was to investigate the differences in vocal characteristics between two types of HT: estrogen therapy (ET) and estrogen-progestogen therapy (E-PT).
Methods : To determine the vocal characteristics in both groups, objective (aerodynamic measurements, vocal range measurements, acoustic analysis, and a determination of the dysphonia severity index) and subjective assessment techniques (perceptual evaluation, videostroboscopic evaluation, and voice handicap index) were used.
Results : The postmenopausal women without HT showed a significantly lower speaking fundamental frequency and were able to phonate lower compared with postmenopausal women with HT. No differences in vocal characteristics were found between postmenopausal women with ET and postmenopausal women with E-PT.
Conclusion : HT seems to counteract the vocal changes caused by menopause. The type of HT did not affect the outcome in this study
The impact of vocal warm-up exercises on the objective vocal quality in female students training to be speech language pathologists
The Impact of Vocal Warm-Up Exercises on the Objective Vocal Quality in Female Students Training to be Speech Language Pathologists
Purpose. the purpose of this study was to determine the impact of a specific vocal warm-up (WU) program-focused on the improvement of the dynamics of the extrinsic and intrinsic laryngeal muscles-on the objective vocal quality in Dutch female students who are getting trained to be speech language pathologists (SLPs). Hypothetically, one can assume that the objective vocal quality will increase after vocal WU exercises in SLPs in comparison with the matched control group that receives no WU program.Methods. This was a pretest-posttest control group design study, in which 45 female future SLPs were randomly assigned into two groups. the experimental group received a well-defined vocal WU program, whereas the control group took 30 minutes of vocal rest. Objective assessment techniques (aerodynamic, vocal range, acoustic measurements, and Dysphonia Severity Index [DSI]) were used.Results. After vocal WU, a significant increased DSI value, increased vocal performance (with lower intensity and higher frequency), and increased fundamental frequency (F-0) were measured.Conclusions. Clinically, there is clear evidence that warming up the vocal mechanism is beneficial to the objective vocal quality and the vocal performance in future SLPs. To what extent the repetition of these vocal WU exercises has the possibility to maintain increased objective vocal quality in these future professional voice users is subject to further research.Ghent Univ Hosp, Dept ENT & Head & Neck Surg, B-9000 Ghent, BelgiumUniv Antwerp Hosp, Dept ENT & Head & Neck Surg, Antwerp, BelgiumFed Univ São Paulo UNIFESP EPM, Ctr Voice Studies, Grad Program Human Commun Disorders, São Paulo, BrazilFed Univ São Paulo UNIFESP EPM, Ctr Voice Studies, Grad Program Human Commun Disorders, São Paulo, BrazilWeb of Scienc
The impact of a voice counseling procedure to select students with normal vocal characteristics for starting a master program in speech language pathology: a pilot study
Objective. The purpose of this study is to determine objective vocal quality, vocal characteristics, and vocal habits in future speech language pathology (SLP) students and to evaluate the possible impact of a provided vocal counseling procedure. A comparison of vocal data was done in SLP students who had and who had not undergone vocal counseling procedure. It is hypothesized that counseling results in good vocal quality, adequate vocal performance, and appropriate vocal hygiene.
Study Design. Randomized controlled study design.
Methods. To determine the vocal quality, questionnaires (Voice Handicap Index [VHI]), subjective (videostroboscopic and perceptual evaluations), and instrumental assessment techniques (aerodynamic, vocal range, acoustic measurements, Dysphonia Severity Index [DSI]) were used. Identical voice assessments were made in 71 students who followed and have not (n = 83) followed the vocal counseling procedure.
Results. The VHI showed the absence of a psychosocial impact of the vocal quality. Thirty percentage of the subjects mentioned hoarseness as the most common vocal complain. Videostroboscopic evaluations revealed normal vocal anatomy and physiology. A significant difference regarding the DSI value was found between the students with (+3.3, 83%) and without (+1.8, 68%) a followed voice counseling procedure.
Conclusion. This vocal counseling procedure is added as a standard procedure when future students gain information about the SLP master program. To what extent the presence and content of the vocal education strategy can influence the choice of the profession as an SLP is subject for further research
