Objective: The aim of this study was to evaluate the reduction in bacterial loading using 2% chlorhexidine gluconate as an irrigating solution in pulpectomized primary teeth. Study design: A randomized, controlled clinical trial was performed that included primary teeth with pulp necrosis. Forty necrotic teeth were included, 20 irrigated with 2% chlorhexidine gluconate (experimental group) and 20 with sterile saline solution (control group); in all cases, 2 microbiological samples from within the canals were taken with sterile paper points, the first after the canal opening and before the first irrigation, and the second after instrumentation and final irrigation, before filling. All samples were evaluated by McFarland's scale. Results: The results were statistically analyzed by the Mann-Whitney U test. After analyzing samples before and after irrigation in the control group (saline), we found a significant decrease of bacterial load (P <0.0002). The same occurred in the chlorhexidine group samples (P <0.0001). When both groups were compared postirrigation,a statistically significant difference was observed in favor of 2% chlorhexidine gluconate.Conclusion: Two percent chlorhexidine gluconate showed a greater reduction of intracanal bacterial loading compared with that observed with sterile saline solution. This irrigating solution is suggested as an alternative for pulpectomy of necrotic primary teeth.

Objective: The aim of the present study was to evaluate the reduction in bacterial loading uing MTAD as an irrigating solution in pulpectomized primary teeth. Study design: A randomized, controlled clinical trial was performed that included primary teeth with pulp necrosis. Sixty necrotic canals were included, 30 irrigated with MTAD (experimental group) and 30 with 1% Na0Cl solution (control group); in all cases, 2 microbiological samples from within the canals were taken with sterile paper points, the first after the canal opening and before the first irrigation, and the second after instrumentation and final irrigation, before obturation. All samples were evaluated by Agar plate method. Results: The results were statistically analyzed by student ‘t’ test. After analyzing samples before and after irrigation in the control group (NaOCl), we found a significant decrease of bacterial load ( p = < 0.001). The same occurred in the MTAD group samples ( p = < 0.001). When both groups were compared post irrigation, a statistically significant difference was observed in favor of MTAD. Conclusion: MTAD can be suggested as an alternative irrigant for pulpectomy of necrotic teeth.

Objective: The aim of this study was to evaluate the effectiveness of oxidative potential water (OPW) as an irrigating solution in reducing bacterial loading in necrotic pulpectomized primary teeth. Study design: Forty necrotic teeth were included, 20 irrigated with OPW (experimental group) and 20 with 1% NaOCl (control group); in both groups, 2 microbiological samples from within the canals were taken with a sterile paper point, the first before irrigation (immediately before opening the crown), and the second after instrumentation and final irrigation (before filling). All samples were evaluated by McFarland's scale. Results: After the samples were analyzed before and after irrigation in the control group, there was a significant decrease in bacterial load, as in the experimental group (P < 0.0001). When both groups were compared post irrigation, no significant difference was observed (P = 0.1519). Conclusion: The OPW was as effective as the NaOCl and is suggested as an alternative for irrigating after pulpectomy of necrotic primary teeth.

The aim of this study is to examine the effects of 6-week Zumba exercises on flexibility, leg strength, back strength and muscular endurance parameters in women aged 25-45. The research group consists of a total of (n=20) women, (n=10) in the experimental group and (n=10) in the control group, between the ages of 25-45 living in Istanbul. The participants in the experimental group were given 60 minutes of Zumba exercises 3 days a week for 6 weeks, and sit-reach, 1-minute sit-up and strength test measurements were made to the participants before and after the exercise program. Participants in the control group were not included in any exercise program. As a result of the analysis, it was determined that there was a statistically significant difference between the participants' flexibility, leg strength, back strength and muscular endurance values between the pre-test and post-test within the group (p< 0.05). In addition, there was no significant difference between the pre-test and post-test values between the groups (p< 0.05). In conclusion; It was determined that zumba exercises applied to the experimental group did not have a significant effect on flexibility, muscular endurance and back strength. In the leg strength parameter, the effect of zumba exercises applied to the experimental group on leg strength was found to be significant at a rate of 34%. In the light of these data, it was concluded that zumba exercises performed in sedentary women have a positive effect on lower extremity strength.

Background/Objectives: This study examined the effects of introducing programming as a technological tool for teachers’ Technological Pedagogical Content Knowledge (TPACK) development.Methods/Statistical Analysis: Thirty-two teachers were divided into two groups, completing different types of TPACK educational programs. The control group’s TPACK training program was based on information and communication technology (ICT), while that of the experimental group was based on programming. To verify the effectiveness of the TPACK training program, tests were administered before and after the educational program. A statistical analysis of questionnaire results also investigated changes resulting from TPACK.Findings: Both the control and experimental groups showed statistically significant improvements in the post-test compared with the pre-test. However, in the detailed areas of TPACK by group, the improvements in the two groups differed. Unlike the control group, the experimental group showed a statistically significant improvement in the knowledge related to technology. This result illustrated that programming is effective in solving the problem of integrating technology into the classroom. In contrast, there was no significant difference in the post-test, as this was applied in the short term. However, programming has been shown to affect Technological Pedagogical Knowledge (TPK), Technological Content Knowledge (TCK), and TPACK. In summary, the results showed that a TPACK educational program based on programming is effective for teachers’ TPACK development. Keywords: TPACK, In-service teacher, Programming, TPACK-P, Educational program

Background: Fan therapy is often suggested for relieving the symptom of dyspnea in patients with advanced cancer, but relevant literature among Asians is limited. Objective: Phase 2 clinical trial to assess the clinical feasibility and outcome of using an electric fan to alleviate the symptom of dyspnea in Chinese patients with advanced cancer. Methods: Thirty patients with advanced cancer having unresolved breathlessness were recruited from Hospice and Palliative Care Centre of Kiang Wu Hospital in Macau. Participants were randomly and equally allocated to the experimental group and the control group, respectively. Outcome Measures: Verbal numerical rating scale (NRS) of breathlessness, respiratory rate (RR), and saturation of peripheral oxygen (SpO2) was collected before and after the intervention. Results: T test was used to analyze the data collected. There was a significant difference in the NRS scores of the experimental group ( P < .01), indicating a significant reduction in the patients’ sensation of breathlessness after fan therapy, whereas no significant difference was found in the objective statistic results of RR and SpO2. No significant difference ( P > .05) was found in the control group for all the 3 variables before and after routine treatment. Conclusion: The results of the study suggested that fan therapy could be effective in alleviating dyspnea in Chinese patients with advanced cancer. It should be considered as one of the nonpharmacological treatment option. Future large-scale phase 3 clinical trials are warranted.

Background: The diagnosis and the treatment for cancer are significant stressors for the patients. It can affect physical as well as psychological well-being. Variations in salivary amylase indicate physiological responses to the stressful experience during chemotherapy. Music therapy is witnessed to decrease psychosocial distress in the oncology setting. Listening to music can positively benefit neurophysiologic and emotional responses as well as promote relaxation, especially beneficial for cancer patients undergoing painful and anxiety-inducing chemotherapy. It is, therefore nurses, who are so familiar with this environment, not only to be aware of this anxiety-producing process but to cope with it and to alleviate it for the patient as much as possible. Objective: The objective of the study was to determine the salivary amylase levels in patients undergoing chemotherapy before and after listening to preferred music. Design: Quasi-experimental repeated measure design. Setting; Experimental and control group were recruited from two oncology units of selected multispecialty hospitals. Participants: Purposive sampling techniques were used to select the study participants. Patients of age group eighteen and above, undergoing first time chemotherapy treatment and the chemotherapy infusion lasts for minimum of 3 hours duration was the inclusion criteria whereas Patients who were unable to listen to music due to hearing problems, those who were with head and neck cancer, diabetes, hypertension, and thyroid problems were excluded from the study. 168 eligible participants were recruited among which 8 were unable to continue. Methods: Saliva was collected from both the study groups before and after the chemotherapy administration. The patient preferred instrumental music intervention was administered for the duration of 3 hours during chemotherapy with the help of mp3 player and musical pillow in the experimental group where the control group had a routine oncology unit care and they were rested on a bed during the chemotherapy administration. The post-tests were done on day 3 and day 5. Results: Significant changes in mean salivary amylase were observed in the experimental group compared to the control group (p˂0.05). Repeated measure ANOVA also showed a significant difference (p˂0.05) in the experimental group at different time points of observation. There was a significant association between the baseline amylase level and stage of cancer in both the experimental and control group (p˂0.05). Conclusion: Music was effective in patients undergoing chemotherapy in terms of reduction in salivary amylase level.

Background: Burning is one of the worst accidents that people may now experience in modern society. One of the most critical problems of burn patients is the anxiety caused by medical treatments such as burn dressing. The present study aimed to determine the effect of rhythmic breathing on the anxiety of dressing change in burn patients. Materials and Methods: This experimental clinical trial was done on 60 burn hospitalized patients in Ayatollah Mousavi educational-therapeutic hospital of Zanjan province in 2017. The sampling was performed continuously and the samples were randomly assigned to control and experimental groups (30 subjects in each group). The data collection tool included a demographic questionnaire and numerical anxiety scale. First, the demographic characteristics questionnaire was completed by the samples. Then, the rhythmic breathing was taught to the experimental group for 20 minutes until complete learning, and they were asked to perform the rhythmic breathing during dressing. Before and after dressing, anxiety was evaluated in the experimental and control groups for 3 consecutive days. After collecting data and entering them into SPSS 20, data were analyzed using descriptive statistics, chi-square test, independent and dependent t test, and Friedman test. Results: Based on the findings of the study, both groups were homogeneous in terms of age, gender, education, percentage and the degree of burn, and there was no statistically significant difference. The results of the Friedman test showed that the anxiety severity had a statistically significant difference in both control and experimental groups before and after the intervention (P<0.001). However, the severity of anxiety after the intervention further reduced in the experimental group compared to the control group, and this reduction was statistically significant in the experimental group (P<0.001). Conclusion: In general, rhythmic breathing is effective in reducing anxiety caused by a dressing change in burn patients. Thus, this method can be used to decrease the anxiety of dressing.
