RESUMEN
BACKGROUND: Echocardiography (ECHO) is a nonprocedure that causes acute stress in children. Fear, anxiety, and fluctuations in children's blood pressure and heart rate can potentially lead to alterations in echocardiographic measurements. The insufficient research on virtual reality pediatric preparation applications, particularly in the context of echocardiographic procedures, underscores the necessity for additional studies focusing on pediatric patients. This study sought to assess the impact of virtual reality applications tailored explicitly for ECHO on children's oxidative stress levels. METHODS: This was a prospective, randomized, controlled experimental study. Forty-eight children (experimental/24, control/24) aged 7 to 12 years who had an ECHO appointment in the pediatric cardiology outpatient clinic in the 3 months from June to August 2019 participated in the study. Participants whose blood analyses showed hemolysis were eliminated, and the study was completed with 37 children in total: 16 children in the experiment and 21 children in the control. Post hoc power analysis was performed for sample adequacy, and the power of the study was found to be 0.99. A 3D film was prepared for the research and applied to the experimental group before the procedure. All children's oxidative stress levels (cortisol, malondialdehyde, nitric oxide) and glutathione levels were checked after ECHO. RESULTS: The stress hormone cortisol and malondialdehyde levels were lower in the 3D-applied experimental group than in the control group. As another crucial anti-stress antioxidant factor, glutathione level increased in the experimental group compared to the control group (Pâ <â .05). CONCLUSION: The research revealed that the 3D film used to prepare ECHO reduces the stress parameters associated with heart risk and may affect the ECHO measurements. At the same time, the study also proved the positive effect of 3D film preparation by increasing the anti-stress factor.

BACKGROUND: With the Virtual Reality (VR) technique, 3D movies can be made for refugee children for pre-operative stress. The study aims to reveal the oxidative responses of the VR technique in pre-operative anxiety in elective surgery in children aged 5-12 years. METHODS: The Study was designed according to the CONSORT checklist with a randomized controlled parallel design. The whole sample (n = 23), VR experimental group (n = 12), and control group (n = 11) were determined according to the total count method prospectively in 6 months. Oxidative stress parameters (Cortisol, Malondialdehyde, Nitric oxide, Glutathione) were measured in blood samples from the first hospitalization (beginning) and before the intervention (pre-operative) in the experimental and control groups. FINDINGS: MDA, NO, and cortisol levels (p < 0.05), which indicate the stress level, are high in all groups. In pre-operative measurements, oxidative parameters were lower in the VR experimental group than in the control group. At the same time, the anti-stress antioxidant factor Glutathione was higher in the VR experimental group in pre-operative measurements. DISCUSSION: The application of 3D film as a VR technique reduces stress parameters in pre-operative stress, and its antioxidant system activating effect has been determined. APPLICATION TO PRACTICE: It can be applied to refugee child groups for pre-operative stress by shooting 3D movies in different languages.

AIM: This study aims to investigate the effects of pure olive oil on mucosal atrophy of the distal colon in rats. <br/><br/>Material and methods: The study included 28 male albino Wistar rats weighing 300-350 g. A total of 28 animals were randomly allocated to four groups: group 1: control group (n = 6); group 2: ostomy group (n = 6); group 3: ostomy + saline group (n = 8); group 4: ostomy + olive oil group (n = 8). By definition, group 1 did not undergo any procedure. The same surgical procedure was performed for groups 2, 3, and 4 as described below. In all animals from these groups, a two-centimeter-long mid-line incision was made and the colon was divided into 5 cm sections, measured from the distal colon to the caecum. Proximal and distal stomas were created 2 cm apart in the midline with the use of single-layer interrupted sutures. All rats were kept under close daily observation until they were terminated postoperatively after the 1st month. Animals from group 2 did not undergo any additional procedures, while those fromgroups 3 and 4 were given 2 mL of saline and olive oil twice a day, respectively. At the end of the 1st month, the rats were re-operated through the same approach. Biopsies were taken from the proximal and distal stomas of all rats in the same manner for further histopathological analysis. <br/><br/>Results: Group 1 showed no significant differences in terms of mucosal thickness, muscular thickness, wall thickness or colonic lumen diameter between the proximal and distal segments of the colon. Although there were significant differences between the proximal and distal colostomies for each parameter in groups 2, 3, and 4, the mucosal thickness, muscular thickness, wall thickness, and colonic lumen diameter differences for proximal and distal ostomies were very small in group 4 when compared to groups 2 and 3. <br/><br/>Conclusion: The administration of pure olive oil through the distal colon before colostomy closure may reduce the difference in diameter between the proximal and distal intestinal segments. As a result, a more straightforward surgical procedure may be achieved.

Due to the increased interest shown in kefir, the present study examined its effects on some developmental characteristics in Drosophila. To compare the results related to kefir, another fermented product, i.e., yogurt, and the raw material of kefir, i.e., milk, were included in the experiment. All three foods were fed to Drosophila by addition to the medium. The results showed that the three foods delayed development in generations F1 and F2. In both generations, the number of adults was lower than that of the control group, but the comparison of the foods among themselves showed no significant difference. Moreover, the negative effect continued in generation F2. Phenotypically abnormal individuals were observed in the experiments, but there was no significant difference. Furthermore, the sex ratio changed in all the groups, including the control group. In the experimental group fed kefir, the sex ratio changed in favor of females, whereas in the other groups, it changed in favor of males. Whether the milk and milk products were fermented did not change the effect on Drosophila, but unexpectedly it delayed development, reduced the number of adults, and changed the sex ratio. It can be concluded that the three foods delayed development and altered the sex ratio in Drosophila.

In the present study, the effect of ascorbic acid (5 mM) on some physiological parameters and three hormones (auxin, abscisic acid, salicylic acid) was determined under heat stress (40 °C) in maize tolerant cv. (MAY 69) and sensitive cv. SHEMAL (SH) at 0 h, 4 h and 8 h. Heat stress reduced total chlorophyll content (CHL), relative water content (RWC) and stomatal conductance (gs) in SH but did not lead to changes in MAY 69 at 4 h and 8 h. However, pretreatment with ascorbic acid increased (CHL), (RWC) and (gs) in SH under heat stress while it reduced MDA content significantly in both cv. We also observed that heat stress led to a reduction in SA level but increased ABA and IAA levels in SH, whereas it increased SA and IAA levels but did not change ABA level in MAY 69 at 4 h. Furthermore, in SH, ASC application under heat stress increased SA level and decreased IAA and ABA levels at 4 h, but it had no effect on SA and ABA at 8 h.

OBJECTIVE: This cross-sectional and descriptive study analysed complementary and alternative medicine (CAM) practices of patients with cancer diagnoses and influencing factors. METHODS: The subjects consisted of 55 cancer patients hospitalized in Canakkale State Hospital between November 2008 and March 2009 and who were willing to participate in the study. Research data were collected using a sociodemographic characteristics form regarding CAM practices of cancer patients and the Beck Hopelessness Scale (total points 20, rising with the degree of hopelessness). Written consent from the head physician of Canakkale State Hospital and verbal consents of the patients were obtained in order for the research to be performed. The data were analysed using the SPSS 13.0 program (numbers and percentages, chi-squared and Mann Whitney U tests). FINDINGS: Of the patients (49.1% female and 50.9% male) 78.2% had been living with a cancer diagnosis for more than two years. Of the 23.6% of patients with breast cancer and 21.8% with lung cancer, 87.2% uses CAM (72.7% received alternative treatment and 65.5% complementary treatment). Alternative treatments apply herbal treatments concomitantly such as honey, garlic; balsam apple, iscum album, tar oil and 29.1% of them only use stinging nettle. As a complementary treatment; 60% of patients pray for healing and 16.4% of them have massage regularly. Patients explained that they were using the alternative medicine in order to mitigate effects of the disease, to prevent its recurrence, to increase blood values, to feel psychologically relieved; and they were using complementary medicine just to feel psychologically relieved. Of 60% patients chose not to share their CAM practice with doctors and nurses. 36.4% of them use CAM on friend advice, 20% under media influence, 36.4% on their own initiative and 21.8% under family influence. The satisfaction from CAM is 61.1%. The rate of those who find alternative medicine expensive is 21.8%. There is statistically no correlation between CAM practice and age, gender, marital status, location they live for a long time, education and financial status of patients (p>0.05). The average of total hopelessness score of patients is 8.09 +/- 2.59, there is no statistically meaningful correlation between hopelessness score average of patients who use CAM and who do not use (p>0.05). CONCLUSION: The cancer patients in the study who live in Canakkale province and in its districts use CAM. CAM practice does not vary by selected sociodemographic characteristics and the hope level. It is important that the health care professionals (nurses, doctors, etc) should be conscious of CAM-drug interactions and notify the patients about the risk.
