Prose Learning

A pretest-posttest design was used to determine the effects of auditory input, visual input, auditory-visual input, and no input on prose learning. The principal result of a multivariate analysis of covariance combined with a multiple-comparison test was a significant difference in favor of auditory input. This difference seemed to be confined to definition items which were the substance of the input as opposed to application items which were not involved explicitly in the input. A difference between the present study and earlier ones was that a shorter exposure of stimuli was employed in the present study, which may have led to results favoring auditory input in contrast to earlier findings favoring visual input.

ABSTRACT Objective: To assess the degree of facial asymmetry associated with subjects with unilateral functional crossbite (CB) in the primary, early/intermediate, and late mixed dentition phases in comparison with a group of subjects without CB. Subjects and Methods: A group of 234 white subjects, 78 with CB (42 girls and 36 boys) and 156 without CB (73 girls and 83 boys), aged 3.9–11.9, grouped according to the dentition phase, were included. Three-dimensional laser scans of the subjects' faces were used to assess facial asymmetry. For each part of the face two-way multivariate analysis of covariance was performed to assess differences among the subjects, and an independent sample t-test was used to assess the significance of the differences between data sets. Results: Within all dentition phases, the subjects with CB had statistically significantly greater facial asymmetry of the whole face than the subjects without CB, with the greatest values in the lower part of the face (P < .05). In the middle part of the face a significant difference was observed in the mixed dentition phases. Conclusions: Children with unilateral functional CB exhibited a greater facial asymmetry than children without this malocclusion in all the dentition phases herein investigated. The greatest differences were seen for the lower part of the face. Further, facial asymmetry in the middle part of the face became clinically relevant in combination with the transition from primary to mixed dentition phase.

Background: One challenging area in psychological pathology pertains to the comorbidity of the psychological disorders. Bipolar disorder can be pointed out among the most critical psychological diseases featuring common psychiatric comorbidity. The purpose of this study is to compare different kinds of memory in Bipolar Disorder with or without obsessive-compulsive disorder (OCD) comorbidity. Methods: Sixty samples selected in 3 groups: 20 bipolar patients, 20 bipolar disorder with OCD comorbidity, and 20 healthy volunteers. Samples were selected using the available sampling method. Data collection tool included 3 questionnaires: Demographic Information Questionnaire, Comprehensive International Diagnostic Interview (CIDI), Wechsler’s Memory Scale. Data analyzed by multivariate analysis of covariance and descriptive statistics. Results: The results of multivariate analysis of variance analysis showed that at the level of 0.001, there was a significant difference at least regarding one of the memory variables, between the subjects of the 3 groups of bipolar/OCD, bipolar disorder and healthy. According to the mean of the groups, the weakest function is related to patients with bipolar/OCD. Conclusion: The results of the study showed that memory damage is more common in the bipolar/ OCD group, which should consider the treatment processes of these patients.

Effect Of Age

Background: Prior concussion studies have shown that objective neurophysiological measures are sensitive to detecting concussive and subconcussive impairments in youth ice-hockey. These studies monitored brain vital signs at rink-side using a within-subjects design to demonstrate significant changes from pre-season baseline scans. However, practical clinical implementation must overcome inherent challenges related to any dependence on a baseline. This requires establishing the start of normative reference data sets.Methods: The current study collected specific reference data for N = 58 elite, youth, male ice-hockey players and compared these with a general reference dataset from N = 135 of males and females across the lifespan. The elite hockey players were recruited to a select training camp through CAA Hockey, a management agency for players drafted to leagues such as the National Hockey League (NHL). The statistical analysis included a test-retest comparison to establish reliability, and a multivariate analysis of covariance to evaluate differences in brain vital signs between groups with age as a covariate.Findings: Test-retest assessments for brain vital signs evoked potentials showed moderate-to-good reliability (Cronbach’s Alpha > 0.7, Intraclass correlation coefficient > 0.5) in five out of six measures. The multivariate analysis of covariance showed no overall effect for group (p = 0.105), and a significant effect of age as a covariate was observed (p < 0.001). Adjusting for the effect of age, a significant difference was observed in the measure of N100 latency (p = 0.022) between elite hockey players and the heterogeneous control group.Interpretation: The findings support the concept that normative physiological data can be used in brain vital signs evaluation in athletes, and should additionally be stratified for age, skill level, and experience. These can be combined with general norms and/or individual baseline assessments where appropriate and/or possible. The current results allow for brain vital sign evaluation independent of baseline assessment, therefore enabling objective neurophysiological evaluation of concussion management and cognitive performance optimization in ice-hockey.

Abstract Objectives The aim of the present study was to compare the accuracy of the conventional illumination method (CONV) and the fluorescence-aided identification technique (FIT) for distinguishing between composite restorations and intact teeth using different fluorescence-inducing devices commonly used for FIT. Materials and methods Six groups of six dentists equipped with one of six different FIT systems each independently attempted to identify composite restorations and intact teeth on a full-mouth model with 22 composite restorations using CONV and, 1 h later, FIT. The entire procedure was repeated 1 week later. Sensitivity, specificity, and positive (PPV) and negative (NPV) predictive values, including 95% confidence intervals (CI), were calculated for CONV and FIT overall and for each device. The influence of examiner age, method, and device on each parameter was assessed by multivariate analysis of variance. Results The sensitivity (84%, CI 81–86%), specificity (94%, CI 93–96%), PPV (92%, CI 90–94%), and NPV (90%, CI 88–91%) of FIT was significantly higher than that of CONV (47%, CI 44–50%; 82%, CI 79–84%; 66%, CI 62–69%, and 69%, CI 68–71%, respectively; p<0.001). The differences between CONV and FIT were significant for all parameters and FIT systems except VistaCam, which achieved no significant difference in specificity. Examiners younger than 40 years attained significantly higher sensitivity and negative predictive values than older examiners. Conclusions FIT is more reliable for detecting composite restorations than the conventional illumination method. Clinical relevance FIT can be considered an additional or alternative tool for improving the detection of composite restorations.

Abstract Communication and interactions are an integral part of care in long-term care settings. Resident variables, such as race and gender, shape communication and interaction between staff and residents. The Quality of Interactions Schedule (QuIS) was developed to measure the quality of verbal and nonverbal interactions among nursing staff and older adults initially for those in acute care and later used as well in a variety of long term care settings. A quantified measurement of the quality of interactions between residents and staff was created to quantify the QuIS. The purpose of this study was to describe the gender and racial differences in scored quality of interactions. Data for the present study was based on baseline data from the Evidence Integration Triangle for Behavioral and Psychological Symptoms of Dementia (EIT-4-BPSD) implementation study. A total of 535 residents from 55 settings were included in the analyses. An analysis of covariance was conducted to determine a difference in QuIS scores between males and females while controlling for age. The second model tested for differences in QuIS scores between blacks and whites while controlling for age and gender. There was not a statistically significant difference in QuIS scores between male and female residents. There was a significant difference in QuIS scores between those who were black versus white, such that those who were black received more positive interactions from staff than those who were white. Future work should focus on a deeper examination of resident factors and staff factors that may influence these interactions.

Physical Activity Patterns

The aim of this study was to assess the physical activity (PA) patterns of youth with intellectual disabilities (ID). PA was monitored for 7 days in 70 participants, 5–15 years old, using accelerometers. There were 32 participants included in the final analysis. Habitual PA and the number of continuous bouts accrued for a range of bout lengths (5–600 s) for light (LPA), moderate (MPA), and vigorous (VPA) PA were calculated. Multivariate analysis of covariance was used to assess differences in the number of continuous bouts by sex, age, and ID group and between week and weekend days. Participants exhibited short sporadic bursts of activity. The number of continuous bouts decreased as the intensity and duration increased. Few differences in PA patterns were reported by sex, ID group, and age group and between week and weekend days, possibly due to the generally low PA levels in this population.

This study is a reinvestigation of the effectiveness of the Trail Making Test in discriminating between brain-damaged ( n = 51) and pseudoneurologic ( n = 72) subjects. All subjects were hospitalized male veterans at the Allen Park Veterans Administration Hospital. An analysis of covariance showed that the pseudoneurologic subjects performed at a significantly higher level than the brain-damaged subjects. Further analysis with two different cutoff scores exhibited unequal discriminatory power throughout the whole range of Trail Making Test scores. These results suggested diagnosing only when the scores were 9 or lower and 13 or higher. This use of extreme scores resulted in an over-all hit rate of 87% in the study. Comparisons with five major subgroupings of the pseudoneurologic subjects yielded only one significant difference: more accurate discrimination with the 12 cut-off score between 10 general-medical and peripheral nerve-damaged subjects (100% correct) and 18 psychotic subjects (39% accuracy).

AbstractIt is generally well known that speech perception is often improved with integrated audiovisual input whether in quiet or in noise. In many health-care environments, however, conventional surgical masks block visual access to the mouth and obscure other potential facial cues. In addition, these environments can be noisy. Although these masks may not alter the acoustic properties, the presence of noise in addition to the lack of visual input can have a deleterious effect on speech understanding. A transparent (“see-through”) surgical mask may help to overcome this issue.To compare the effect of noise and various visual input conditions on speech understanding for listeners with normal hearing (NH) and hearing impairment using different surgical masks.Participants were assigned to one of three groups based on hearing sensitivity in this quasi-experimental, cross-sectional study.A total of 31 adults participated in this study: one talker, ten listeners with NH, ten listeners with moderate sensorineural hearing loss, and ten listeners with severe-to-profound hearing loss.Selected lists from the Connected Speech Test were digitally recorded with and without surgical masks and then presented to the listeners at 65 dB HL in five conditions against a background of four-talker babble (+10 dB SNR): without a mask (auditory only), without a mask (auditory and visual), with a transparent mask (auditory only), with a transparent mask (auditory and visual), and with a paper mask (auditory only).A significant difference was found in the spectral analyses of the speech stimuli with and without the masks; however, no more than ∼2 dB root mean square. Listeners with NH performed consistently well across all conditions. Both groups of listeners with hearing impairment benefitted from visual input from the transparent mask. The magnitude of improvement in speech perception in noise was greatest for the severe-to-profound group.Findings confirm improved speech perception performance in noise for listeners with hearing impairment when visual input is provided using a transparent surgical mask. Most importantly, the use of the transparent mask did not negatively affect speech perception performance in noise.

Background: Infertility can cause low marital satisfaction. Marital satisfaction has an important effect on infertile couples’ health. Objective: This study aimed to assess the effect of relationship enrichment training on improving the marital satisfaction of infertile couples. Methods: This randomized clinical trial was conducted on 50 infertile couples in the infertility center of Fatemieh Hospital in Hamadan, Iran in 2018. Participants were matched for demographic characteristics and randomly assigned to intervention and control groups (each group had 25 couples). Informed consent was obtained from all participants. The Enrich Marital Satisfaction questionnaire and demographic information were used to collect data before the study and two months after the intervention. Two trained midwifery students taught only the intervention group the relationship enrichment topics in seven sessions (each session = 90 minutes). The data were analyzed by SPSS Statistics version 21 using analysis of covariance, independent t-test, chi-square, and Mann–Whitney. The significance level was set at p ≤ 0.05. Results: There was no significant difference in demographic and obstetric information between the two groups (p >0.05). The mean of marital satisfaction in the intervention group significantly increased among women and men from 151.00 ±28.61 to 154.88 ±22.62 and from 152.56 ±27.33 to 159.24 ±22.14, respectively, (p <0.001). Conversely, the mean of marital satisfaction decreased among women and men from 158.13 ±13.86 to 146.25 ±19.53 and from 164.25 ±17.00 to 153.17 ±27.50 in the control group (p=0.02). Conclusion: Relationship enrichment training can be effective in promoting the marital satisfaction of infertile couples.
