Publicación The Effects of Menopause on Vocal Folds’ Vibratory Characteristics of Female Professional Voice Users(Elsevier, 2025-05-31) Barro Fiuza, Mauro; Lã, Filipa M.B.; Coronado, Pluvio; Roberto, Magda SofiaIntroduction Menopause has been associated with changes in the vocal folds; however, whether these changes impact on vocal folds’ oscillation and collision patterns is still unknown. Materials and Methods Phonation and collision threshold pressures (PTP and CTP, respectively) were compared between premenopausal and postmenopausal female professional voice users (FPVUs), allocated into levels 1 and 2 according to professional use of their voice (ie, singers/singing teachers and schoolteachers, respectively). Audio, electroglottographic, and intraoral pressure signals were recorded while participants performed diminuendo sequences on the syllable /pa/ at pitches A3, E4, and A4. Hormonal profiles and self-perceived voice symptoms were also assessed. Results Voice-related menopausal symptoms were self-perceived as mild in postmenopausal FPVUs. No statistically significant differences in PTP and CTP were found between professional groups for the interaction between reproductive status (ie, premenopausal and postmenopause) and professional level (ie, singers/singing teachers and schoolteachers) for any of the analyzed pitches, despite significant differences in concentrations of pituitary hormones and estradiol. No significant correlations between hormones and voice metrics could be found. Conclusions The increasing numbers of menopausal FPVUs and the great individuality in degree of severity of menopause-related voice symptoms justify further investigations, including professional voice users, especially those complaining of more severe menopause-related voice symptoms.Publicación Contributions of music therapy and of prenatal singing to maternal mental health, maternal attachment, and neonatal behavior(Elsevier, 2025-04-10) Carvalho, E.; Justo, João Manuel Rosado De Miranda; Lã, Filipa M.B.; Queirós, A.; Panela, Ryan A.; Botelho, M.; Roberto, Magda S.Background Listening to music during pregnancy is associated with better neonatal behavior; however, contributions of prenatal singing to neonatal behavior are still unknown. Also, contributions of acoustic propagation of maternal humming inside the womb on fetal and neonatal behavior are still not understood. Methods Low obstetric risk pregnant women (N = 24) were sequentially allocated into three groups: 1) control group (CG) without prenatal singing; 2) music therapy group (MTG); and 3) vocal training group (VTG). Depression, Anxiety and Stress Scales (DASS) and Antenatal Maternal Attachment Scales were applied at 32 GW and also at 37 GW. DASS, Postnatal Maternal Attachment Scales, and Neonatal Behavioral Assessment Scale (NBAS) were applied between one week and one month after birth. Results For MTG: prenatal attachment was improved at 37 GW; newborns range of state was higher when compared with CG newborns; lower scores of anxiety and of stress assessed at 37 GW were associated with higher neonatal autonomic regulation; after birth, lower maternal levels of depression were associated with newborns' higher social orientation. For VTG: anxiety assessed at 37 GW associated negatively with social orientation; after birth, DASS total score associated negatively with autonomic regulation. Conclusion MTG seems to favor prenatal attachment, and neonatal range of state. Apparently prenatal singing (present at both MTG and VTG) improves the association between maternal mental health and newborns' social and self-regulatory competencies.
