Purpose This study explored the role of auditory feedback in the regulation of oral–nasal balance in speech. Method Twenty typical female speakers wore a Nasometer 6450 (KayPentax) headset and headphones while continuously repeating a sentence with oral and nasal sounds. Oral–nasal balance was quantified with nasalance scores. The signals from 2 additional oral and nasal microphones were played back to the participants through the headphones. The relative loudness of the nasal channel in the mix was gradually changed so that the speakers heard themselves as more or less nasal. An additional amplitude control group of 9 female speakers completed the same task while hearing themselves louder or softer in the headphones. Results A repeated-measures analysis of variance of the mean nasalance scores of the stimulus sentence at baseline, minimum, and maximum nasal feedback conditions demonstrated a significant effect of the nasal feedback condition. Post hoc analyses found that the mean nasalance scores were lowest for the maximum nasal feedback condition. The scores of the minimum nasal feedback condition were significantly higher than 2 of the 3 baseline feedback conditions. The amplitude control group did not show any effects of volume changes on nasalance scores. Conclusions Increased nasal feedback led to a compensatory adjustment in the opposite direction, confirming that oral–nasal balance is regulated by auditory feedback. However, a lack of nasal feedback did not lead to a consistent compensatory response of similar magnitude.

Purpose This study explored the role of auditory feedback in the regulation of oral–nasal balance in speakers of Brazilian Portuguese. Method Twenty typical speakers of Brazilian Portuguese (10 male, 10 female) wore a Nasometer headset and headphones while continuously repeating stimuli with oral and nasal sounds. Oral–nasal balance was quantified with nasalance scores. The signals from 2 additional oral and nasal microphones were played back to the participants through the headphones. The relative loudness of the nasal channel in the mix was gradually changed, so that the speakers heard themselves as more or less nasal. Results A repeated-measures analysis of variance of the mean nasalance scores of the stimuli at baseline, minimum, and maximum nasal feedback conditions demonstrated significant effects of nasal feedback condition ( p < .0001) and stimuli ( p < .0001). Post hoc analyses demonstrated that the mean nasalance scores were lowest for the maximum nasal feedback condition. The scores of the minimum nasal feedback condition were significantly higher than 2 of 3 baseline feedback conditions. The speaking amplitude of the participants did not change between the nasal feedback conditions. Conclusions Increased nasal signal level feedback led to a compensatory adjustment in the opposite direction, confirming that oral–nasal balance is regulated by auditory feedback. However, reduced nasal signal level feedback resulted in a compensatory response that was lower in magnitude. This suggests that, even in Brazilian Portuguese, a language with phonetic and phonological vowel nasalization, decreased nasality was not perceived as critically as increased nasality by the speakers.

INTRODUCTION: The enhancement of nurses’ risk perception plays a significant role in their preparedness during disasters and emergencies. Therefore, this study aimed to investigate the effect of educational workshops on disaster risk perception in nurses METHODS: This randomized controlled field trial study included 62 nurses working at Razi Hospital, Birjand, Iran. The participants were divided into intervention and control groups. The intervention group was then requested to participate in a one-day intensive educational workshop based on the current national standards. The workshop content included a combination of lecturing methods, round-table exercises, and film display. The data were collected using the demographic characteristic form and researcher-made questionnaires measuring the nurses’ risk perception during disasters and emergencies. Subsequently, the data were analyzed using independent t-test, repeated measures analysis, and Bonferroni post hoc tests. FINDINGS: The mean total score of risk perception were significantly higher in the intervention group before, immediately, and two months after the workshop session, compared to those in the control group (P˂0.001). CONCLUSION: The implementation of nurses’ national preparation program during disasters and emergencies can result in an increase in the nurses’ risk perception during these events. Therefore, regarding the importance of nurses’ preparedness in confrontation with disasters and emergencies, it seems necessary to integrate the National Preparedness Program into the educational programs immediately after recruitment and in the form of in-service courses.

BackgroundPain is a common complication after laparoscopic surgery. This study aimed to examine the effect of an early mobilisation programme on postoperative pain intensity after laparoscopic surgery.MethodsA randomised controlled clinical trial was conducted on 80 patients who underwent laparoscopic surgery in Shahid Beheshti Hospital in Kashan, Iran. The patients were randomly allocated to intervention (n=40) and a control (n=40) group. In the intervention group, an early mobilisation programme was implemented in two rounds. The patient’s perceived pain was assessed using a Visual Analogue Scale 15 min before and 30 min after each round of early mobilisation. Data were analysed through the independent samples t, χ2 and Fisher’s exact tests and the repeated measures analysis.ResultsThe repeated measures analysis showed that the mean pain scores have been decreased over time (F=98.88, p<0.001). Considering the observed interaction between time and the intervention, the t test was used for pairwise comparisons and showed that the mean pain score was not significantly different between the two groups in 15 min before the first round of early mobilisation (p=0.95). However, the mean pain in the intervention group was significantly less than the control group in all subsequent measurements (p<0.05).ConclusionEarly mobilisation programmes such as the one implemented in the current study are easy and inexpensive and can be implemented safely for the reduction of pain after laparoscopic surgeries.

The purpose of this study was to evaluate the effect of metal orthodontic brackets on the accuracy of electronic apex locator (EAL). The actual canal lengths (ACL) of 40 mandibular incisor teeth were determined. Then, the teeth were randomly divided into two groups ( n = 20 ). Orthodontic metal brackets were applied in the first group, and no brackets, in the second group. The working length of each tooth was measured with an EAL under 3 test conditions according to the distance between the lip clip and sample tooth. Data were analyzed using one-way repeated measures analysis of variance and Tukey’s post hoc tests ( p = 0.05 ). In the bracketed samples, when the lip clip was located at 1 cm and 2 cm from the samples. The mean differences between the EAL measurements and ACLs were statistically higher than those when the samples were located 3 cm from the lip clip ( p < 0.05 ). There were also statistically significant differences between EAL measurements and ACLs in the bracketed samples located 1 and 2 cm from the lip clip ( p < 0.05 ). In the nonbracketed group, the differences between EAL measurements and ACLs were not statistically significant in the samples located 1, 2, and 3 cm from the lip clip ( p > 0.05 ). Use of orthodontic metal brackets can negatively influence the accuracy of the electronic apex locator when the distance between the lip clip and bracket was short. A minimum of 3 cm distance should be kept between the lip clip and tooth in order to make consistent electronic measurements.

The aim of this study was to evaluate eight methods for aligning the orientation of two different local coordinate systems. Alignment is very important when combining two different systems of motion analysis. Two of the methods were developed specifically for biomechanical studies, and because there have been at least three decades of algorithm development in robotics, it was decided to include six methods from this field. To compare these methods, an Xsens sensor and two Optotrak clusters were attached to a Plexiglas plate. The first optical marker cluster was fixed on the sensor and 20 trials were recorded. The error of alignment was calculated for each trial, and the mean, the standard deviation, and the maximum values of this error over all trials were reported. One-way repeated measures analysis of variance revealed that the alignment error differed significantly across the eight methods. Post-hoc tests showed that the alignment error from the methods based on angular velocities was significantly lower than for the other methods. The method using angular velocities performed the best, with an average error of 0.17 ± 0.08 deg. We therefore recommend this method, which is easy to perform and provides accurate alignment.

Maintaining stable physiological responses may be important for the growth and development of preterm infants. The purpose of our study was to evaluate the effects of olfactory stimulation with maternal breast milk on the occurrence of abnormal physiological responses in preterm infants. With a non-equivalent control group pretest-posttest design, 13 preterm infants in the experimental group and 18 preterm infants in the control group completed the intervention. The intervention was implemented three times a day for 5 days in a row with 2 hours of administration per intervention. The frequency of abnormal physiological responses was assessed over 6 days (one day before intervention administration and 5 days during intervention administration). With repeated-measures analysis of variance, the experimental group showed a significantly lower frequency of apnea than the control group ( p = .021). Olfactory stimulation with maternal breast milk may be an effective nursing intervention for reducing apnea episodes in preterm infants.

Background: Wet cupping, furthermore mentioned cupping, decreases blood pressures through the level of negative air pressures added by hydrostatics filtration pressure to reinforce the power of fluids filtration in capillaries. However, an appropriate negative air pressure to decrease blood pressure remains an uncertainty.Purpose: This study aimed to analyze negative air pressure differences on cupping in decreasing blood pressures in hypertensive patients.Methods: This is a quasi-experimental design conducted in three Community Health Centers in Langsa City, Aceh, Indonesia. The samples were 36 hypertensive males with age from 45 to 55, who were randomly stratified into two groups with cupping pressures 400 mbar (n=18) as the control group; and 540 mbar (n=18) as the intervention group. The cupping session was performed to each group on T1 (alkahil) point and in the middle line of both shoulders blade points. The systolic blood pressure (SBP) and diastolic blood pressures (DBP) were measured by validated automatic sphygmomanometer. The follow-up periods were one week and two weeks. The data were then analyzed by repeated measures ANOVA.Results: Cupping pressure of 400 mbar decreased the mean of SBP and DPB with a p-value of 0.450 and 0.026, respectively after two weeks of intervention. Meanwhile, cupping pressure of 540 mbar decreased the mean of SBP and DBP with a p-value of 0.006 and 0.057, respectively. Tests of within-subjects resulted in the p-value of 0.250 (SBP) and 0.176 (DBP) after two weeks of intervention. There were no significant differences in SBP and DBP between the intervention group and the control group.Conclusion: The cupping pressure between 400 mbar and 540 mbar could reduce blood pressure; however, the cupping pressure of 540 mbar yielded greater effect in decreasing blood pressure than the 400 mbar. Negative air vacuum pressure loads on cupping to decrease blood pressure should be considered between 400 to 540 mbar, and further studies are needed.

Objective: The present study aimed to investigate the effectiveness of emotionally-focused couple therapy (EFCT) and acceptance and commitment therapy (ACT) in the quality of interpersonal relationships among couples with marital conflicts. Materials and Methods: This was a quasi-experimental study with a pretest-posttest design and delayed follow-up. The study population consisted of 39 couples with marital conflicts referring to Behzisti counseling centers in Tayebad, Iran, within the second half of 2018 and first half of 2019. The participants, including 13 couples receiving EFCT, 13 couples receiving ACT, and 13 couples as the control group, were selected using convenience sampling. For the experimental groups, nine EFCT sessions and eight ACT sessions were held, and the control group was not subjected to any intervention. The research tools were Sanaeichr('39')s Marital Conflicts Questionnaire and Pierce’s Quality of Interpersonal Relationships Questionnaire that the couples of the three groups completed in three stages, namely pretest, posttest, and follow-up. Repeated measures analysis of variance, Bonferroni test, and SPSS statistical software (version 23) were used to analyze the data. Results: Repeated measures analysis of variance showed that ACT was more effective in the quality of interpersonal relationships among couples with marital conflicts than EFCT (P<0.001). Conclusion: The obtained results of the present study revealed that ACT was more effective than EFCT in the improvement of the quality of interpersonal relationships among couples with marital conflicts.

Objective: To verify the effect of recreational soccer on bone mineral density and sarcopenia in the elderly. Methods: Fourteen elderly people aged 65.9 ± 3.4 years were selected. They were separated into two groups: the intervention group and the control group; the intervention group played recreational soccer for 12 weeks on two days of the week. Assessments were performed for bone mineral density and body muscle mass before and after the intervention. For statistical analysis, the repeated measures ANOVA with Bonferroni’s post hoc test was used. Results: After 12 weeks, there was a significant change in bone mineral density in the region of the total femur (p = 0.020). Analyzing the participants’ sarcopenia, no significant results were found after the intervention period. Conclusion: Playing recreational soccer causes a significant improvement in the total femur and maintains bone regions in the spine, whole body, and femoral neck. Also, it promotes a removal from the threshold for sarcopenia screening in the elderly.
