Prevalence of voice problems and associated risk factors in electronic sports players
(Springer Nature, 2026) Birol, Namık Yücel; Yaşar Gündüz, Esra; Tutuş, Zübeyir
Background Electronic sports (esports) has rapidly emerged as a global phenomenon, engaging millions of players and viewers. Previous research has extensively examined health concerns in this population, including musculoskeletal disorders, ocular fatigue, sleep disturbances, and cardiometabolic risks. However, despite the intensive and prolonged vocal use required during team-based gaming communication, voice disorders have not been investigated in esports players. This study aimed to examine the prevalence of voice problems and associated risk factors in this population. Methods A cross-sectional survey was conducted with 87 esports players aged 18–32 years in Türkiye. Data were collected using a researcher-developed questionnaire that addressed vocal symptoms, phonotraumatic behaviors, lifestyle, and health-related factors. In addition, the Voice Handicap Index-10 (VHI-10-TR) was administered. A cutoff score of ≥ 7 on the VHI-10-TR was used to identify players at risk for voice disorders. Descriptive statistics, chi-square tests, and logistic regression analyses were performed. Results Based on the VHI-10-TR cutoff score (≥ 7), 20.7% of the participants were classified as having voice problems. Significant associations were found between voice problems and longer daily speaking time during gameplay (p = .009) as well as weekly gaming hours exceeding 21 (p = .009). Commonly reported symptoms included throat dryness (49.4%), vocal fatigue (35.6%), and throat discomfort (26.4%). Poor air quality in gaming environments (p = .036) and frequent consumption of spicy/fatty foods (p = .037) were significant lifestyle-related risk factors. Difficulty hearing conversational speech was also associated with increased likelihood of voice problems (p = .045). Logistic regression indicated that unadjusted odds of reporting voice problems were three to five times higher in relation to these factors, though none remained significant in the adjusted model. Conclusions Approximately one in five esports players reported voice problems, highlighting their potential vulnerability as a risk group. Environmental and lifestyle conditions, alongside prolonged gaming and communication, contribute to vocal strain. Preventive strategies focusing on vocal hygiene, gaming environment improvement, and early screening may help safeguard vocal health in this population.

Noise-induced hearing loss in firefighters: an audiological evaluation
(SPRINGER, 13 January 2026) Osmanoğlu, Hülya; Bayrak, Nevruz Nur; Köroğlu Koçyiğit, Azize Arzu; Altun, Eymen; Hüyüktepe, Veli Can
Abstract Background The aim of this study was to evaluate the hearing thresholds, speech understanding abilities, and otoa coustic emissions tests of firefighters to determine the effects of occupational noise exposure on auditory health. This descriptive study consisted of 25 firefighters and 25 healthy individuals with normal hearing as the control group. Fire f ighters exposed to noise outside of working hours, those using ototoxic medications, or those with other health risk factors were excluded from the study. Hearing functions of all participants were assessed using pure-tone and high frequency audiometry, speech tests, and otoacoustic emissions measurements. Results Firefighters’ pure-tone hearing thresholds were significantly higher compared to the control group, and hearing loss was observed, particularly at high frequencies (4000 Hz and above). In the speech test results, SRT thresholds were also found to be statistically significantly higher in the study group (p<0.05). Dynamic range was found to be narrower in the study group. DPOAE and TEOAE results showed that firefighters exposed to noise at certain frequencies had significantly lower SNRs. Conclusions These findings support similar studies in the literature, demonstrating that long-term noise exposure has potential negative effects on hearing health in firefighters, particularly high frequencies indicate that hearing thresholds can be affected. Keywords Occupational noise, Noise pollution, Vulnerable occupations, Workplace exposures

Functional and sensory properties of legume-derived aquafaba in angel cakes
(05.01.2026) Sarı Gençağ, Burcu; Turhan, Gülşah
This study evaluated aquafaba obtained from four legumes: chickpea (CP), mung bean (MB), green lentil (GL), and dermason/white bean (WB) as a complete egg-white substitute in angel cake. Functional properties (foaming capacity and stability; emulsion stability) and cake quality (pH, protein, ash, moisture, colour, baking loss, volume index, and sensory evaluation, n=25) were assessed. The egg-white control (C) showed the highest foaming capacity (608.52%) and stability (92.04%). Among aquafaba samples, CP, MB, and GL exhibited comparable foaming performance (≈145–148% capacity; ≈76–78% stability), whereas WB was significantly lower (116.59%; 56.37%) (p < 0.05). Cakes with aquafaba had lower pH and generally lower protein than the con- trol, with GL the lowest; moisture was highest in MB and WB, while ash showed no difference. Colour analysis revealed darker crumbs with reduced lightness and yellowness. Baking loss in- creased with aquafaba (MB and WB highest), while volume index decreased; CP retained the most significant volume among the aquafaba groups. Sensory results showed no significant differences among C, CP, and GL, while MB and WB scored lower. Overall, CP and to some extent GL provided the most favourable technological and sensory performance, emphasising legume type as a key factor for successful egg replacement in cakes.

The effects of Pilates training combined with whole-body vibration on balance and mobility in people with multiple sclerosis: A single-blind randomized controlled clinical trial
(Bayçınar Tıbbi Yayıncılık, 2026) Salamci, Mustafacan; Ozkul, Çağla; Yücesan, Canan; Güçlü Gündüz, Arzu
Objectives: This study aims to investigate the effects of Pilates training combined with whole-body vibration (WBV) on balance, functional mobility, core muscle endurance and power, lower extremity strength, upper extremity performance, and fatigue in people with multiple sclerosis. Patients and methods: This randomized controlled trial was conducted between December 2023 and September 2024. Thirty-four participants (9 males, 25 females; mean age: 36.65 ± 12.24 years; range 20 to 65 years) were included in the study and randomized into two groups: Pilates-WBV (n=17) and Pilates (n=17). The Pilates-WBV group received both Pilates and WBV training, while the Pilates group received only Pilates training. Both groups received training twice a week for six weeks. The primary outcomes included posturography, the Activities-Specific Balance Confidence Scale, core muscle endurance and power tests, the five times sit-to-stand test, the timed up-and-go test, and the 6-min walk test. The secondary outcomes included the nine-hole peg test, the Fatigue Severity Scale, and the Fatigue Impact Scale. Assessments were conducted at baseline and after intervention. Results: Both groups showed significant improvements in single-leg stance stability, limits of stability, balance confidence, core muscle endurance and power, functional mobility, upper extremity performance, and fatigue (p<0.05). Double-leg stance stability and walking distance improved only in the Pilates-WBV group (p<0.05). The Pilates-WBV group also showed greater improvements in trunk flexor endurance and core power (modified push-up test) compared to the Pilates group. Conclusion: Pilates training combined with WBV improved core stability, walking endurance, and physical performance more than Pilates training alone in people with multiple sclerosis.

Experiences of International Speech–Language Pathology Students: A Phenomenological Study
(3 October 2025) Cankuvvet, Nurdan; Selvi-Balo, Semra; Yaşar-Gündüz, Esra; Yırtık, Havva Nur
Background International students often encounter systemic and individual challenges, especially in language-intensive fields like Speech–Language Pathology (SLP). Although their experiences are documented in well-established contexts, little is known about newer host countries such as Türkiye, where enrolments have recently risen. Understanding this is crucial for identifying barriers and support needs, impacting outcomes, and the internationalisation of SLP education. Aim This study explores the educational experiences of international undergraduates in the Speech–Language Pathology program at Anadolu University, Türkiye. Methods and Procedures Using a phenomenological design, data were collected through focus group interviews with nine female students and were analysed thematically. Conclusions and Implications International SLP students in Türkiye encountered familiar challenges—language barriers, uneven preparation, and integration difficulties—amplified by diverse entry pathways and local dynamics. Nevertheless, they demonstrated resilience by developing self-discipline and valuing educational quality despite mismatched expectations. The findings emphasise the need for institutional support: clearer communication of norms, structured orientation, and culturally responsive supervision could help reduce systemic barriers, while mentoring and buddy systems might further aid integration and clinical readiness, benefiting both students and the profession.
