Objective This study aims to observe whether Kryptonite Bone Cement combined with a standard Kirschner wire, instead of autogenous bone grafts, increases bone healing and mechanical strength in rats with tibia fractures. Methods The study included sixteen rats, which were divided into two groups as a control group (n=8) and an experimental group (n=8). After segmental fractures were made in both groups, intramedullary fixation of tibia procedures were conducted with the use of a Kirschner wire. No additional procedures were performed inthe control group, but Kryptonite Bone Cement was applied in the experimental group. The rats were evaluated clinically, radiologically and histologically4 times; immediately after the operation, and atthe 1st, 3rd, and 6thweeks following surgery. Results One rat from the experimental and one from the control group had both wound dehiscence and wound site infection. No recovery was observed in any rats either in the control or experimental group immediately after surgery. During week 1, callus formation was identified in 5 rats in the experimental group (p=0.0072), and during week 3, fracture lines disappeared in 4 rats in the experimental group (p=0.064); the differences between control and experimental groups were statistically significant. During week 6, no statistical significance was observed in radiological assessments for the control group and experimental group (p=0.71). The rate of non-union was higher in the control group (37.50%) than in the experimental one, while the rate of complete fusion was higher in the experimental group (87.50%) than that in the control group. Conclusion Osteoconductivity and ergonomic qualities of Kryptonite Bone Cement prove helpful in bone repair. Future studies to be conducted in a prospective and randomized manner will be effective on demonstrating the effectiveness of Kryptonite Bone Cement.

Abstract Background Many non-union animal models have been developed to explore the problems surrounding fracture healing. However, the existing models are not perfect and cannot satisfy all non-union studies. This study aimed to make a non-union model of the tibia in rats by cauterization of the posterior of 2 mm on both sides of the fracture end after open osteotomy of the tibia and fixing the fractured tibia with a Kirschner wire 0.8 mm in diameter. Methods For this study, 96 female adult Sprague-Dawley (SD) rats were used. The rats underwent surgery to produce a tibial open fracture and were fixed with a 0.8-mm diameter Kirschner wire. In 48 of the rats, the periosteum proximal and distal to the fracture end was cauterized. Results At 2, 4, 6, and 8 weeks after surgery, radiological and histological analysis showed typical physiological healing in the control group, and the healing rate was 100% at 6 weeks. But the non-union group was characterized by resorption of the fracture ends with few callus formations and no bridging callus formation, and the healing rate was 0% at 8 weeks. Conclusions This method represents a reproducible model to create atrophic non-unions. This model provides a new option for studying the basic healing mechanisms and evaluating new therapies for bone regeneration and treatment of non-unions.

The study aims at evaluating health-generating function of humor therapy in a hospital ward hosting children suffering from respiratory pathologies. The main scope of this study is to investigate possible positive effects of the presence of a clown on both the clinical evolution of the on-going disease, and on some physiological and pain parameters. Forty-three children with respiratory pathologies participated in the study: 21 of them belonged to the experimental group (EG) and 22 children to the control group (CG). During their hospitalization, the children of the EG interacted with two clowns who were experienced in the field of pediatric intervention. All participants were evaluated with respect to clinical progress and to a series of physiological and pain measures both before and after the clown interaction. When compared with the CG, EG children showed an earlier disappearance of the pathological symptoms. Moreover, the interaction of the clown with the children led to a statistically significant lowering of diastolic blood pressure, respiratory frequency and temperature in the EG as compared with the control group. The other two parameters of systolic pressure and heart frequency yielded results in the same direction, without reaching statistical significance. A similar health-inducing effect of clown presence was observed on pain parameters, both by self evaluation and assessment by nurses. Taken together, our data indicate that the presence of clowns in the ward has a possible health-inducing effect. Thus, humor can be seen as an easy-to-use, inexpensive and natural therapeutic modality to be used within different therapeutic settings.

This research attempted to explore the effects of divergent and convergent tasks on the successful reading of EFL students at the preparatory stage. To verify the analysis, the null hypothesis was established that states "There are no differences of statistical significance at the level of (0,05) among the mean of scores of the experimental group who study according to divergent and convergent task technique and the mean of the scores of the control group who study according to the regular method".  The experimental approach is used by designing two equivalent experimental groups of 32 students studying the technique proposed, and an 8-week (2019-2020) control group of 32 students, three classes each week using the Google Classroom Platform and Telegram. The present study utilized the platform Google Classroom (GC) and Telegram as an educational platform to assist students during their course learning process. The writing skills test was administered after checking with the experts. The results show that there are statistical differences at level (0,05) between the average of the experimental and control groups' reading skills and those of the experimental group. This difference is because the experimental group uses divergent and convergent tasks.

The aim of this study was to investigate the influence of 24-h sleep deprivation on the muscle strength of young, healthy and physically fit people. The research material consisted of physical education students. In total, 67 people participated in the study, including 38 women and 29 men. Respondents were divided into an experimental group “E” of 44 persons subjected to 24-h sleep deprivation and a control group “C” of 23 persons. Students completed the Epworth Sleepiness Scale (ESS) measuring daytime sleepiness. Students performed measurements of the maximum strength of knee joint extensor and flexor muscles. Measurements of muscle strength of flexors and extensors of the knee were taken on a UPR-02 A/S chair with Moment II by Sumer software. ANOVA (analysis of variance) was used to determine the significance of differences between experimental “E” and control “C” group. Statistical significance was defined at the level of p ≤ 0.05. Statistically significant differences were observed in the change of strength levels between groups at the strength moments of right (p < 0.05, η2p = 0.16) and left (p < 0.05, η2p = 0.08) knee muscles extensor. Changes in extensor muscle strength are significant for students with left dominant legs.

Wound dressing is a skill which must be able to be performed by all nurses. If the practical ability of a nurse is weak, it will affect the quality of patient care. The objective of this research is to study the effectiveness of the latex wound model for wound dressing training on wound dressing skills of the nursing student. The latex wound model is a device used in practice which is made from rubber. The samples are the 60 second-year nursing students. Simple random sampling was applied in the selection of samples to be an experimental group and a control group for 30 persons per group. The latex wound model was provided to the experimental group for wound dressing skill training at the dormitory for a seven day period. A personal data questionnaire, wet dressing skill evaluation form, and dry dressing skill evaluation form were used for data collection. The data were analyzed using descriptive statistics, Wilcoxon Signed Ranks Test and Mann-Whitney U Test. The results indicated that: 1) the mean score of wet dressing skill and dry dressing skill after the intervention were significantly higher than before the intervention (p < .05); 2) the mean score of wet dressing skill and dry dressing skill of the experimental group were higher than that of the control group, who was given the explanation of research procedures and the use of latex wound model, at statistical significance (p < .05). The findings imply that the use of the latex wound model for wound dressing training could enhance the wound dressing practical skill of the nursing students.
