Effect of Reminiscence Training on Professional Communication Skills in Pediatric Nursing Staff

Introduction: The main way to improve the quality of care, especially for children, is to improve nursing communication skills. Objective: The purpose of this study was to determine the effect of reminiscence training on professional relationship communication skills in pediatric nursing staff. Materials and Methods: This study was a quasi-experimental design that consisted of all babies and infants’ nursing staff working in an educational hospital of Bushehr City, Iran, in 2019. A total of 84 nurses (41 cases were obtained for the experimental group and 43 cases for the control group) took part in the study. The samples were randomly assigned to the experimental and control groups. In this study, the questionnaires of nurses’ professional communication skills and nurses’ communication skills with hospitalized infant mothers were used. The validity and reliability of the questionnaires were confirmed. First, the pre-test was taken from the experimental and control groups. The experimental group received 8 hours reminiscence training session. Post-test was taken from both groups immediately and one month after the intervention. To analyze data, descriptive indices, the Chi-square test, independent t-test, and repeated measures ANOVA were used. Results: Comparison of demographic data in two groups showed no significant difference between them in terms of scores of both instruments before the intervention. The independent t-test showed that the mean scores of communication with mothers and communication with colleagues one month after the intervention were significantly different (P=0.001) between the experimental and control groups. The results of repeated measures ANOVA showed that the interaction effect between group and time was statistically significant, and the trend of mean scores changes in nursing staff professional relationships with colleagues (P=0.03) and mothers (P=0.001) during the study period (before, immediately after, one month after intervention) were different between the experimental and control groups. Conclusion: Training based on reminiscence effectively improves nurses’ professional communication. So we suggest that this training be included in nurses’ educational programs.

Addendum to: Murre (2021). The Godden and Baddeley (1975) experiment on context-dependent memory on land and underwater: a replication

The analysis in Murre (2021) should have been done with a repeated measures ANOVA with an order effect as a between-subjects covariate. A reanalysis reinforces the conclusion that this study was not a successful replication of Godden & Baddeley (1975).

Five-year Randomized Clinical Trial on the Performance of Two Etch-and-rinse Adhesives in Noncarious Cervical Lesions

SUMMARY Objectives: To evaluate the 5-year clinical performance of two-step etch-and-rinse adhesives in noncarious cervical lesions (NCCL). Methods and Materials: The sample comprised 35 adults with at least two similar-sized NCCL. Seventy restorations were placed, according to one of the following groups: Adper Single Bond 2 (SB) and Ambar (AM). The restorations were placed incrementally using a resin composite (Opallis). The restorations were evaluated at baseline and after 6 and 18 months and 5 years using some items of the FDI criteria. The differences in the ratings of the two materials after 6 months, 18 months, and 5 years were performed with Friedman repeated measures ANOVA by rank and McNemar test for significance in each pair (α=0.05). Results: Five patients did not attend the 60-month recall. No significant differences were observed between the materials for any criteria evaluated. Twenty-one restorations failed (12 for SB and 9 for AM) after 60 months. Thus, the retention rate for SB at 60 months were 55.6% for SB and 71% for AM (p=0.32). After 60 months, 12 restorations (6 for SB and 6 AM) showed some loss of marginal adaptation (p=1.0). Slight marginal discoloration was observed in 10 restorations (6 for SB and 4 AM; p=0.91). Five restorations (2 for SB and 3 for AM) showed recurrences of caries (p=1.0). Conclusions: Both two-step etch-and-rinse adhesives—Adper Single Bond 2, a polyalkenoic acid-containing adhesive, and Ambar, a 10-methacryloyloxydecyl dihydrogen phosphate (MDP)-containing adhesive—showed acceptable clinical performance after 60 months.

Students Engagement and Development of Generic Skills in Gamified Hybrid Service-Learning Course

Hybrid Service-Learning, an emerging trend of combining co-curriculum course embedded with service-learning instructional strategies in online settings, has increasingly gained popularity, as many service-learning educators are moving into online platforms. The ongoing COVID-19 pandemic has accentuated its needs, thus forcing education systems worldwide to find alternatives to face-to-face instructions, one of them being Hybrid Service-Learning. This has prompted many researchers to attempt utilising gamification in online courses to increase students’ engagement. The purpose of this research was to report a gamified Hybrid Service-Learning (GAMYSEL) through students’ level of engagement proposed by Schlechty, used as a data classification to compare students’ scorings in their earning of points, badges, level and leaderboards. The results of the study indicated that, the students’ levels of engagement were relatively high through Advocacy Hybrid-Service Learning approach, where majority of them achieved the Strategic Compliance and Optimal Engagement categories. The students’ generic skills were further analysed with one-way repeated measures ANOVA and it was discovered that, GAMYSEL had positive impacts in developing these skills in five stages of service-learning. Both of these findings suggest that student’s engagement and generic skills had a significant effect on students learning after the use of GAMYSEL.

Enhancing the differentiation of walking and standing via the ratio of plantar pressures

Differentiation of standing and walking based on plantar pressures is helpful in developing strategies to reduce health risks in the workplace. In order to improve the differentiation ability, the paper proposes a new metric for posture differentiation, that is, the pressure ratio on the two anatomical plantar regions. The plantar pressures were collected from 30 persons during walking and standing. After verifying the normal distribution of the pressure ratio by the Monte Carlo method, two-way repeated-measures ANOVA was conducted for the pressure ratios. The advantage of the pressure ratio over two conventional pressure metrics (the average pressure and the peak pressure) is demonstrated by its much larger size effect. Furthermore, the pressure ratio permits to establish value ranges corresponding to walking and standing, which are less influenced by specific person factors, thus facilitating the design of a standardized posture recognition system. The underlying mechanism underlying the pressure ratio is discussed from the aspect of biomechanics of movement.

Microhardness evaluation of root dentin after using resin sealer solvents

Background. This study aimed to assess the effects of methyl ethyl ketone (MEK) and ethyl acetate (EA) on dentin microhardness, used as resin sealer solvents. Methods. Eighty halves of single-rooted teeth were randomly divided into four groups to apply MEK, EA, chloroform, or saline solution. Vickers hardness values were measured for three root levels before and after the direct application of solvents for 5 and 15 minutes or a 1-minute application with ultrasonic agitation. The results were analyzed using repeated-measures ANOVA, and adjustments were made for comparisons with Bonferroni tests. Results. The dentin microhardness decreased in all the solvent groups (P<0.05). The changes in microhardness increased with prolonged exposure times, except for the saline solution group. Chloroform exhibited the most significant decrease in value. Furthermore, ultrasonic agitation elicited a more substantial decline in values. Conclusion. MEK and EA might be preferred over chloroform as a solvent for resin sealers because they offer an attenuated decrease in dentin microhardness and do not have gutta-percha-dissolving properties.

The ability of a submaximal cycle ergometer test to detect longitudinal changes in VO2max

Background The purpose of the present study was to examine the ability of a submaximal cycling test to detect longitudinal changes in maximal oxygen uptake (VO2max) and examine the conformity between changes in measured and estimated VO2max over a time span of 5–8 years. Methods A total of 35 participants (21 men and 14 women), aged 29 to 63 years, performed the Ekblom-Bak (EB) submaximal cycle test for estimation of VO2max and a maximal treadmill running test for direct measurement of VO2max. The baseline tests were conducted between 2009 and 2012, and the follow-up tests were completed 5 to 8 years later. Pearson’s coefficient of correlation (r) and paired sample t-test were used to analyse the association between change in measured and estimated VO2max. Random and systematic errors between the measured and estimated VO2max were evaluated using Bland-Altman plots. Repeated measures ANOVA were used to test differences between changes over time. Results There was no significant change in mean measured VO2max between baseline and follow-up (p = 0.91), however large individual variations were noted (− 0.78 to 0.61 L/min). The correlation between individual change in measured and estimated VO2max was r = 0.75 (p < 0.05), and the unstandardised B-coefficient from linear regression modelling was 0.88 (95% CI 0.61 to 1.15), i.e., for each litre of change in estimated VO2max, the measured value had changed 0.88 L. The correlation between baseline and follow-up errors (the difference between estimated-measured VO2max at each occasion) was r = 0.84 (p < 0.05). With regard to the testing procedure, repeated measures ANOVA revealed that there was no significant difference between the group who exercised at the same work rates at baseline and follow-up (n = 25), and those who required a change in work rate (n = 10). Conclusions The EB test detected a change in VO2max with reasonably good precision over a time span of 5–8 years. Further studies are needed to evaluate if the test can be used in clinical populations and in subjects with different medications.

Changing maladaptive beliefs among individuals with coronary heart disease using video information

Many individuals with coronary heart disease (CHD) have maladaptive beliefs which might increase anxiety and depression. This study investigates the impact of using video information to convey facts and correct misconceptions about CHD in individuals. 150 individuals with CHD were assigned to either the control group or one of two experimental groups. The participants completed the York Cardiac Beliefs Questionnaire in the baseline measure immediately after first viewing the video (time 1), and after viewing the video for six times within two weeks (time 2). The Beck Anxiety Inventory and Beck Depression Inventory II were completed in the baseline and at time 2. Multiple repeated measures anova shows that after the intervention, participants’ maladaptive beliefs, anxiety and depression were reduced in both experimental groups. Yet, it did not happen in the control group. It indicates that the video information corrects maladaptive beliefs, and reduces anxiety and depression levels in individuals with CHD.

Color and translucency stability of CAD/CAM restorative materials

Aim: This study assessed the color and translucency stability of a polymer infiltrated ceramic network (PICN) and compared it with a resin composite (RC) and a feldspathic ceramic (FEL). Methods: Disc-shaped samples of a PICN (Vita Enamic), a feldspathic ceramic (Vitablocks Mark II), and a resin composite (Brava block) were prepared from CAD/CAM blocks. PICN and RC surfaces were finished with a sequence of polishing discs and diamond paste. FEL samples received a glaze layer. The samples were subjected to 30-min immersions in red wine twice a day for 30 days. CIEL*a*b* coordinates were assessed with a spectrophotometer at baseline and after 15 and 30 days of immersion. Color alteration (ΔE00) and translucency parameter (TP00) were calculated with CIEDE2000. Average roughness was measured before the staining procedures. Color difference and translucency data were analyzed with repeated-measures ANOVA and Tukey’s tests. Roughness was analyzed with the Kruskal-Wallis test. Results: Roughness was similar among the experimental groups. All materials had their color alteration significantly increased from 15 to 30 days of staining. PICN reached an intermediate ΔE00 between FEL and RC at 15 days. PICN revealed a color alteration as high as the composite after 30 days. No statistical difference was observed regarding translucency. Conclusion: PICN was not as color stable as the feldspathic ceramic at the end of the study. Its color alteration was comparable to the resin composite when exposed to red wine. However, the translucency of the tested materials was stable throughout the 30-day staining.

The effects of a sled push at different loads on 20 metre sprint time in well-trained soccer players

This study determined the effects of a single sled push at different loads on sprint performance in competitive male soccer players. Twenty male competitive outfield soccer players (age 19.6±1.3y, body mass 73.6±8.2kg) were split into experimental (n=10) and control groups. In the experimental group, 20m linear sprint time was measured immediately before and 5, 6 and 7minutes after the sled push with either 50 or 100% body mass. The control group performed the 20m sprints only. A repeated measures ANOVA comparing control and experimental groups revealed no effects of time, group or time by group interaction for either experimental condition (all P>0.05). The repeated measures ANOVA compared the experimental conditions revealed effects of time (P=0.034) and group (P=0.002), but not time by group (P>0.05). The effects sizes demonstrated within group effects on sprint time that were small to moderate (-0.26 to 0.71) and trivial to small (-0.31 to 0.09) for the 50% and 100% body mass condition, respectively. These findings demonstrate that a sled push has no significant effect on 20 m sprint time in competitive footballers. If coaches continue to prescribed a sled push before sprinting, a single 15 m push with 50% body mass could have positive benefits.
