RESUMO

PURPOSE: The Dysphonia Severity Index (DSI) is an objective multiparameter index of voice quality that measures and describes overall voice quality. Some studies have suggested that the reliability of devices for DSI measurement should be examined. We explored the feasibility of DSI measurements using the Dr. Speech (DRS) device, verified its effectiveness for clinical voice measurements and intradevice reliability, and examined the correlation between the DSI and self-evaluations of voice problems. METHODS: Seventy adult participants (including individuals with voice problems and healthy adults) underwent objective and subjective voice assessments. These data were then used to establish a DSIDRS model and test the intradevice (DRS device and Praat software) reliability. The clinical validation of the DSIDRS was conducted by measuring the DSI of six other participants and comparing the observed and predicted perceived voice quality as expressed by the G score (of the GRBAS scale). Moreover, the relationship between the DSI measurements and participants' self-evaluations of voice problems was investigated by analyzing the correlation between the DSI and the Voice Handicap Index (VHI). RESULTS: The DSIDRS discriminated 80% of participants' voice quality ratings. There were strong correlations between the DSI and variables measured by the DRS device and Praat software. Furthermore, there was no significant correlation between the DSIDRS and VHI. CONCLUSION: The DRS device can perform DSI measurements. Objective voice measurements and perceptual voice ratings reflected different aspects of vocal function and its effects. These factors should be considered in clinical practice settings.

RESUMO

In the Korean Peninsula's southern estuaries, the distributive characteristics of epilithic diatoms and the important environmental factors predicting species occurrence were examined. The collection of diatoms and measurements of water quality and land-use were performed every May between 2009 and 2016, with no influence from the Asian monsoon and snow. Throughout the study, 564 diatoms were classified with first and second dominant species of Nitzschia inconspicua and N. perminuta. Based on diatom appearance and standing crops, the 512 sampling stations were divided into four groups by cluster analysis, and two regions, namely the West and East Sea. Geographically, G1, G2, G3, and G4 were located in the East Sea, Southeast Sea, West Sea, and Southwest Sea, respectively. Canonical correspondence analysis (CCA) results indicated that environmental factors, such as turbidity, electric conductivity (EC), and total phosphorus (TP), significantly influenced the distribution of epilithic diatoms. A random forest model showed that major environmental factors influencing the diatom species appearance included EC, salinity, turbidity, and total nitrogen. This study demonstrated that the spatial distribution of epilithic diatoms in the southern estuaries of the Korean Peninsula was determined by several factors, including a geographically higher tidal current-driven turbidity increase and higher industrial or anthropogenic nutrient-loading.

RESUMO

Dysphonia Severity Index (DSI) is an objective multi-parametric measurement of voice quality, which has been widely used in different countries. Studies indicate that DSI may be influenced by vocal pathology, age and geographical factors, whereas gender does not significantly affect DSI. The purpose of this study was to investigate the effects of gender and age on the DSI and related parameters in a Shanghainese population. The present study measured the DSI and the parameters maximum phonation time (MPT), highest fundamental frequency (HF0), lowest intensity (LI) and Jitter in 187 Shanghainese subjects, including 106 young adults aged 18-23 years (52 males and 54 females) and 81 children aged 7-9 years (44 boys and 37 girls). Two-way analysis of variance indicated that HF0 was significantly higher in female subjects than in male subjects, in both young adults and children. Gender was not significantly associated with MPT, LI, jitter or DSI. With regard to age, MPT and DSI were significantly higher in young adults than in children, and HF0 and LI were significantly lower. No significant associations between age and jitter were detected. In terms of clinic significance, the results of this study may contribute to the establishment of a normal reference range for Shanghainese DSI values, and the influence of gender and age on DSI and its separate components.

RESUMO

Sexuality is often bound together with sexual function in contemporary sexual health literature; however, sexuality is a multidimensional phenomenon that has a broader historical concept and cultural meaning. In addition to a significant global decline in sexual function, women may experience decline in emotional satisfaction and physical pleasure up to 4.5 years after giving birth. Midwives have an important role in raising conversations about sexuality on a regular basis during antenatal visits, and informing couples about the decline of libido, desire and orgasm, which may lead to reduction in sexual intercourse frequency, particularly in the last trimester and puerperium.

RESUMO

The purpose of this study was to determine whether there are dialectal and gender related differences in nasalance of main Mandarin vowels and three sentences in 400 Chinese normal adults. The mean nasalance score difference for dialect and gender was significant (p < .001) in all speech materials. For different dialects, the average nasalance scores show that Chongqing > Beijing > Shanghai > Guangzhou for the nasal sentence, oro-nasal sentence, /a/, /i/ and /u/. In addition, the average nasalance scores of females were higher than those of males for all speech materials in all dialects. The clinical significance of this study can be helpful in making nasalance clinical decisions for Chinese people with cleft palate, hearing disorders and dysarthria with resonance disorders. It also shows the theoretical and socio-cultural features for linguists considering dialects and gender.

RESUMO

To improve the water quality of Shingal Reservoir, a eutrophic lake in South Korea, field tests were performed to assess the influence of water temperature on water quality improvement (WQI) ability of domestic plant-mineral composites (PMCs). Interestingly, Cyanobacterium was found to be dominant even in low-temperature seasons, especially winter leading to more effective for diatom growth. Factors such as phytoplankton, biological oxygen demand (BOD) and phosphorous showed high WQI over 70% at 20 degrees C, but declined to 40% at temperatures above 25 degrees C. WQI for Cyanobacteria decreased with increasing water temperature, whereas for diatoms WQI was 90% regardless of water temperature. Additionally, bacterial density and total nitrogen showed very low WQI without water temperature. Collectively, the results indicate that high water temperature decreased WQI ability of a PMC to control phytoplankton (Microcystis aeruginosa) and increased their ability to control diatoms.

RESUMO

Coblation devices are now widely used in arthroscopic surgery and they show a very low incidence of intraoperative complications. We experienced a case where the tip of the wand separated and migrated into the posterior knee compartment in an arthrofibrotic knee. The free wand tip was identified and then extricated from the popliteal hiatus of the knee with using C-arm fluoroscopic control. To the best of our knowledge, this is the first report of its kind involving coblation wands. We describe this complication to show that the use of coblation devices can lead to unexpected problems and it is imperative to inspect all instruments before and after each surgical use.
