The impact of virtual reality on pain management during normal labor: A systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: To evaluate the impact of virtual reality on pain management during normal labor. METHODS: A systematic search was performed in September 2021 through PubMed, Cochrane Library, Scopus, and ISI web of science. We selected randomized clinical trials (RCTs) that compared virtual reality in the intervention group versus placebo or no intervention in the control group among laboring women during their normal delivery. Revman software was used for performing our meta-analysis. Our primary outcome was the pain score evaluated during the labor process by the Visual Analog Scale (VAS). Our secondary outcomes were anxiety and satisfaction scores during childbirth in addition to the duration of the first and second stages of labor. RESULTS: Eight RCTs met our inclusion criteria with a total number of 466 patients. We found virtual reality was linked to a significant reduction in the VAS pain score during labor compared to the control group (MD = -1.40, 95% CI [-1.83, -0.96], p < 0.001). The anxiety score during labor was significantly reduced among the virtual reality group (SMD = -1.15, 95% CI [-2.18, -0.12], p = 0.03). Moreover, virtual reality significantly improved the satisfaction score during labor (MD = 15.58, 95% CI [4.93, 26.22], p = 0.004). However, there were no significant differences between virtual reality and control groups regarding the duration of the first and second stages of labor. CONCLUSIONS: Virtual reality is an effective technique for reducing anxiety, increasing satisfaction, and improving pain management during normal labor.

Improvement of Coronary Calcium Scores After Bariatric Surgery in People with Severe Obesity.

BACKGROUND: Obesity is an independent risk factor for cardiovascular diseases. Coronary artery calcium (CAC) is a direct measure of coronary atherosclerosis. The study investigated the effect of bariatric surgery on CAC scores in people with severe obesity subjected to laparoscopic sleeve gastrectomy (LSG). METHODS: This prospective study included 129 people with severe obesity in two groups; the LSG group (n=74) subjected to surgery and the diet group (n=55), managed by a diet regimen and lifestyle modification. Cardiovascular risk was assessed by Framingham risk score (FRS) and coronary calcium score (CCS) measured by computed tomography initially and after 3 years. RESULTS: The two groups had a comparable CAD risk before treatment according to FRS or CCS. After treatment, CCS improved significantly in the LSG group (p=0.008) but not in the diet group (p=0.149). There was no correlation between FRS and CCS (r=0.005, p=0.952). Treatment resulted in significant weight reduction and improved fasting blood glucose and lipid profile in the two groups. The change of weight, blood glucose, and HDL, and remission of diabetes mellitus (DM) were significantly higher in the LSG group compared to the diet group. CONCLUSION: LSG may reduce the risk of developing future cardiovascular comorbidities evidenced by reducing CAC scores. Significant weight reduction and improvement of cardiovascular risk factors may recommend LSG as a cardioprotective procedure in people with severe obesity.
