The Effect of Yoga on Early Clinical Outcomes and Pulmonary Functions in Patients Scheduled for Bariatric Surgery: a Randomized Controlled Study.

PURPOSE: The present research was undertaken to investigate the effect of yoga on pulmonary function and early clinical outcomes in patients scheduled for bariatric surgery. MATERIALS AND METHODS: This research with a randomized control group was performed on patients scheduled for bariatric surgery between October 2021 and June 2022 in the General Surgery Clinic of a University Hospital in Eastern Turkey. The sample consists of 100 randomized patients who received yoga breathing exercises and routine care. Pulmonary function test (PFT), posteroanterior chest X-rays (CXR), 6-min walk test, and oxygen saturation (SpO2) were applied as a pretest. The researcher practiced yoga for 40 min every day of the week. Post-test measurements were performed at the end of the yoga practice. Control group patients underwent the tests at the same intervals without any modifications to the standard clinical protocol. RESULTS: The difference between the control and experimental groups was significant in terms of post-test PFT measurements (p < 0.001). In the CXR of the patients, a statistically significant improvement was determined in 61.5% of the patients with yoga breathing practice (p < 0.001). Also, there was a significant increase in the 6-min walk test and SpO2 values in the experimental group (p < 0.05). CONCLUSION: Yoga practice positively affected the pulmonary function values of the patients.

The Effect of Ozonated Olive Oil on Neovascularization in an Experimental Skin Flap Model.

OBJECTIVE: Angiogenesis is an important factor for flap viability. It has been reported that ozonated oil contributed to improved neovascularization in an acute cutaneous wound healing model. This study was undertaken to evaluate the effect of ozonated olive oil on vascular endothelial growth factor (VEGF)-mediated neovascularization of skin flaps in rats. STUDY DESIGN: A skin flap model was established in 21 rats and evaluated within 3 groups. No treatment was given to the rats in group 1. Olive oil and ozonated olive oil were topically applied (twice daily) to the flap surface for 7 days in groups 2 and 3, respectively. Immunohistochemical staining was performed to analyze the expressions of VEGF and CD34. RESULTS: The mean numbers of VEGF- and CD34-positive staining microvascular structures were 8.86 (SD, 1.35) and 10.29 (SD, 1.80) in group 1, 15.00 (SD, 1.41) and 15.57 (SD, 1.72) in group 2, and 25.14 (SD, 2.41) and 25.00 (SD, 2.16) in group 3. The VEGF and CD34 expressions in group 3 were significantly higher than those in group 2 (P < .001). Their expressions in group 2 were significantly higher than those in group 1 (P < .001). CONCLUSIONS: Both ozonated olive oil and olive oil improved neovascularization when they were topically applied on skin flaps. The effect of ozone was more prominent.
