Voice fundamental frequency (VFF), phonation time, and duration characteristics were analyzed for 15 female and 18 male esophageal speakers to determine whether acoustic differences existed as a function of speaker sex. A significant difference was found between the mean fundamental frequency of esophageal speech produced by men and that produced by women. The average VFF of women was approximately seven semitones higher than that established for men. Without regard to speaker sex, the average voice fundamental frequency for the total sample of 33 talkers was 24.9 semitones (69 Hz). Mean fundamental frequencies for individual speakers ranged from 12.9–43.7 semitones (33–200 Hz). No significant sex differences were found for VFF variability, phonation time, and duration measures. The findings highlight the need for investigators to control for acoustic differences between male and female esophageal speakers.

ObjectiveTo evaluate the Sex differences in Sport-related Concussion in Japan.BackgroundWe dont't have the knowledge about the sex differences in SRC in Japan.Design/MethodsThe study design was retrospective study. Facility is Toho University Ohashi Medical Center Neurosurgery Sports-related head injury clinic. The search period is April 2017 to February 2018. Inclusion criteria were as follows: 1) Sports-related head injury cases, 2) Physician-diagnosed Sports-related concussion, 3) Underwent evaluation by the same neurosurgeon, 4) More than 28 days continued follow-up. The following items were compared male and female. The examination items were as follows: 1) Age/sex, 2) competition item, 3) prior concussion, 4) Migraine history, 5) persistent post concussive symptoms. Statistical analysis used t test.ResultsThe 140 selected cases were 114 male (Group M: GM) and 26 female (Group F: GF). The mean Age of both GM and GF was 20 years. The most majority competition item of GM was Rugby football. On the other hand, GF was lacrosse. 42 cases of GM and 9 cases of GF suffered prior concussion (p > 0.05, no significant). 19 cases of GM and 6 cases of GF had migraine history (p > 0.05, no significant). 37 cases of GM and 16 cases of GF had PPCS (p < 0.05).ConclusionsOur result suggests that female players explain the significant difference in the prevalence of PPCS in Japan.

Abstract Introduction: Hyperphosphatemia is associated with unfavorable outcomes, and the percentage of patients presenting with this condition in hemodialysis (HD) in kidney foundation units in the state of Santa Catarina (SC) is historically higher than that of patients in the state of Tocantins (TO). Objective: To assess the frequency of consumption of the main dietary sources of phosphorus and to compare them between the two states. Methodology: A cross-sectional study was carried out involving 123 patients, 66 of SC and 57 of TO: 52% were men, average age was 46.9 ± 15.7 years, and mean HD time 48 (57-71) months. A food frequency questionnaire (FFQ) with 33 items that are dietary sources of phosphorus was applied. A consumption score was calculated for sources of organic, inorganic, and total phosphorus, and the six-month average of phosphatemia was obtained. Results: The mean phosphatemia of SC patients was higher (6.2 ± 1.5 vs 4.7 ± 1.3 mg/dL, p <0001) than TO patients, as well as the prevalence of hyperphosphatemia (62% vs 28%; p <10001). In the total sample, the foods most frequently consumed were milk and beans. Comparing the frequency of consumption between the two states, a significant difference was found in 17 items. In TO, beef and beans were the foods most frequently consumed, and in SC, fourteen other items of the FFQ (pork, sausages, dairy products, etc.) were the most frequently consumed. Phosphatemia correlated with the frequency of consumption of inorganic phosphorus sources. Conclusion: the frequency of consumption of several items was different between the states, and this explains the differences in phosphatemia between the two regions.

Spontaneous speech samples of 27 children with trisomy-21 type Down’s syndrome and 66 normal children were tape-recorded and analyzed for mean fundamental frequency, standard deviation, and range. Results indicate that the mean speaking fundamental frequency (SFF) level for the sample of children with mongolism was significantly higher than the mean SFF level for the control sample. Approximately 50% of the children with mongolism had mean SFF levels exceeding the highest mean SFF level of their matched controls. In only two cases did the mean SFF for a child with mongolism fall below the mean SFF level for control children of the same age and sex. No child with mongolism exhibited a mean SFF level below the lowest mean SFF for any control subject. The subject in question is the clinical observation that children with mongolism typically have low voice fundamental frequency levels.

The purpose of this study was to compare the male and female medical students’ perceptions of the flipped classroom (FC) using the Zoom online platform during the COVID-19 pandemic. A mixedmodality study proceeded for first-year undergraduate medical students (n = 149). Three topics (learning how to learn, stress management and doctor-patient communication) were flipped using the Zoom platform. Following the flipping, relevant videos and PowerPoint slides were sent to the students. Home assignments were done through the online classroom. The students were then made to answer a questionnaire on their perceptions of FC consisting of 5-point Likert items. In addition, a focus group discussion (FGD) was carried out with voluntary participation (n = 13) for an in-depth discussion of flipped teaching. The quantitative data were analysed using the independent t-test, and Atlas.ti was used to analyse the qualitative data. For most of the Likert statements, there was no significant difference (p > 0.05) between the mean results obtained by the male and female students. For example, for the item “The learning material was available before class time”, both the male (mean [SD] = 1.857 [0.443]) and female (mean [SD] = 1.966 [0.365]) respondents confirmed the learning material’s availability before class time (p = 0.121). However, the mean result obtained by the male respondents for the variable “I understood the topics in lesser time compared to the traditional lecture method” was higher than the mean result obtained by the female participants by 0.236, which was statistically significant (95% CI [0.373, –0.100], p = 0.001). Modified FC teaching for the “learning skills” course is thus an effective teaching method. The male students took significantly lesser time understanding the three included topics compared to the female students.

The aim of our study was to evaluate the morphogenetic variability as a marker of smoking dependency in adult smokers versus controls and to investigate the presence and the degree of morphogenetic variability difference between male and female smokers versus same gender controls. The cross-sectional study evaluated 241 smokers and 185 nonsmoker individuals as controls. We analyzed 17 homozygous recessive characteristics (HRC). There was a significant difference in the individual variations of 17 HRCs between the controls and smokers (??2=61.400, p<0.001; for females ??2=79.440, p<0.001; for males ??2=84.972, p<0.001). The mean values of HRCs significantly differed between smokers and controls (MV?SEM(Controls) -4.79?0.13, MV?SEM(Smokers) -5.70?0.12; p<0.001). For males, presence of 6/17 (35.29% genetic homozygosity) HRCs (OR=6.12) was to the certain degree predictor for smoking dependency. Higher degree of genetic homozygosity, changed variability and male gender, might be some among potential numerous factors that could have impact on smoking development and dependence.

This paper presents the results of Open Quotient measurements in EGG signals of young (18 to 30 year old) and elderly (59 to 82 year old) male and female speakers. The paper further presents quantitative results on the relation between the OQ and the perception of a speaker's age. Higgins & Saxman (1991) found a decreased OQEGG with increasing age for females, whereas the OQEGG in sustained vowel material increased for males as the speakers age increased. In Linville (2002), however, the spectral amplitudes in the region of F0 (obtained by LTAS-measurements of read speech material) increased with increasing age independent of gender; this could be interpreted indirectly as an increasing OQ. We measured the OQEGG not only for sustained vowels, but also in vowels taken from isolated words. In order to analyse the relation between breathiness in terms of an increased OQ and the mean perceived age per stimulus a perception test was carried out in which listeners were asked to estimate speaker's age based on sustained /a/-vowel stimuli varying in vocal effort (soft - normal - loud) during production. The results indicated the following: (i) The decreased OQ for elderly females originally found by Higgins & Saxman is not apparent in our data for sustained /a/-vowels. For our female speakers no significant difference between the OQ of young and old speakers was found; for elderly males, however, we also found an increasing OQ with increasing age.(ii) In addition, a statistically significant increased OQEGG occurs for the group of the elderly males for the vowels from the word material. (iii) Our results show a strong positive relation between perceived age and OQ in male voices. Regarding (i) and (ii), at least the male speaker's voice becomes more breathy as age increases. Considering (iii), increased breathiness may contribute to the listener’s perception of increased age.
