To verify the advantages of Virtual Fixtures (VFs) by comparing the result of guide plate navigation (GPN) and VFs in robot-assisted osteotomy. Robot-assisted surgery has been extensively applied in traditional orthopedic surgeries. It fundamentally improves surgeries' cutting accuracy. In addition, many key techniques have been applied in bone cutting to increase the procedure's safety in various ways. In this paper, two robot-assisted osteotomy methods are proposed. Three operators with no osteotomy experience performed plane cutting with the assistance of a robot. GPN and VFs were applied to assist the Sawbones cutting. Each operator has five attempts using each method to perform bone cutting, distance errors and angular errors were recorded. The advantage of Sawbones is that there is no influence from soft tissues and blood. It can give a more precise measurement. The results show that both methods have high accuracy with the robot's assistance. VFs have higher accuracy in comparison with GPN. With GPN, the mean distance and angular error of the three operators were 2.974 ± 0.282 mm and 4.737 ± 0.254°. With VFs, the mean range and angular error of the three operators were 1.857 ± 0.349 mm and 2.24 ± 0.123°, respectively. VFs limited the robot's end in the planned area, increasing the accuracy and safety of robot-assisted osteotomy. [ABSTRACT FROM AUTHOR]

Objective: At present, the use of particular radial hemostatic devices after coronary angiography (CAG) or percutaneous coronary intervention (PCI) has become the primary method of hemostasis. Most control studies are based on the products already on the market, while only a few studies are on the new hemostatic devices. The aim of this study is to compare a new radial artery hemostasis device which is transformed based on the invention patent (Application number: CN201510275446) with TR Band (Terumo Medical) to evaluate its clinical effects.Methods: In a prospective randomized clinical trial, 60 patients after CAG or PCI were randomly divided into two groups, patients in the trial group (CD group) using a new radial artery hemostasis device to stop bleeding and the control group (TR group) using the TR Band. The method is to collect relevant data of the two groups and compare the differences in hemostasis, local complications, and patient discomfort between the two groups.Results: The hemostatic devices in both groups achieved adequate hemostasis, and there was no failure to stop bleeding. The new radial artery hemostasis device was better than the TR band in pain and swelling (P < 0.05). There were no significant differences in bleeding, hematoma, ecchymosis, skin damage, and local infection between the two groups (P > 0.05).Conclusions: The sample of the new radial artery hemostasis device can stop bleeding effectively at the puncture site after CAG or PCI and is not inferior to the TR Band balloon hemostatic device in safety and is better in comfort.

Objective: The previous meta-analysis has assessed that distal transradial access (dTRA) in anatomical snuffbox is safe and effective for coronary angiography and intervention and can reduce radial artery occlusion. However, since the publication of the previous meta-analysis, several observational studies have been added, so we performed an updated meta-analysis to include more eligible studies to compare distal transradial access in anatomical snuffbox with conventional transradial access (cTRA).Method: Pubmed, Embase, and Cochrane Library databases were searched for relevant studies from the literature published until 5 January 2021 to evaluate catheterization/puncture failure, hematoma, radial artery spasm, radial artery occlusion (RAO), access time, fluoroscopy time, radiation dose area product, total procedure time, and hemostatic device removal time. The pooled odds ratio (OR), weighted mean difference (WMD), and standardized mean difference (SMD) with 95% confidence interval (95% CI) were calculated for dichotomous and continuous variables, respectively.Results: A total of 9,054 patients from 14 studies were included in the meta-analysis, and we found no significant difference in catheterization/puncture failure (OR = 1.94, 95CI [0.97, 3.86], P=0.06), hematoma (OR = 0.97, 95CI [0.55, 1.73], P=0.926), radial artery spasm (OR = 0.76, 95CI [0.43, 1.36], P=0.354), total procedure time (SMD = 0.23, 95CI [-0.21, 0.68], P=0.308), or radiation dose area product (WMD = 216.88 Gy/cm2, 95CI [-126.24, 560.00], P=0.215), but dTRA had a lower incidence of RAO (OR = 0.39, 95CI [0.23, 0.66], P < 0.001), shorter hemostatic device removal time (WMD = -66.62 min, 95CI [-76.68, -56.56], P < 0.001), longer access time (SMD = 0.32, 95CI [0.08, 0.56], P=0.008), and longer fluoroscopy time (SMD = 0.16, 95CI [-0.00, 0.33], P=0.05) than cTRA.Conclusion: Compared with the cTRA, the dTRA has a lower incidence of radial artery occlusion and shorter hemostatic device removal time, which is worthy of further evaluation in clinical practice.

Objective: This study aimed to investigate the time course of cardiac rupture (CR) after acute myocardial infarction (AMI) and the differences among different rupture types., Method: We retrospectively analyzed 145 patients with CR after AMI at Shanxi Cardiovascular Hospital from June 2016 to September 2022. Firstly, according to the time from onset of chest pain to CR, the patients were divided into early CR (≤24 h) ( n  = 61 patients) and late CR (>24 h) ( n  = 75 patients) to explore the difference between early CR and late CR. Secondly, according to the type of CR, the patients were divided into free wall rupture (FWR) ( n  = 55) and ventricular septal rupture (VSR) ( n  = 90) to explore the difference between FWR and VSR., Results: Multivariate logistic regression analysis showed that high white blood cell count (OR = 1.134, 95% CI: 1.019-1.260, P  = 0.021), low creatinine (OR = 0.991, 95% CI: 0.982-0.999, P  = 0.026) were independently associated with early CR. In addition, rapid heart rate (OR = 1.035, 95% CI: 1.009-1.061, P  = 0.009), low systolic blood pressure (OR = 0.981, 95% CI: 0.962-1.000, P  = 0.048), and anterior myocardial infarction (OR = 5.989, 95% CI: 1.978-18.136, P  = 0.002) were independently associated with VSR., Conclusion: In patients with CR, high white blood cell count and low creatinine were independently associated with early CR, rapid heart rate, low systolic blood pressure, and anterior myocardial infarction were independently associated with VSR., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Objective: Since the World Health Organization (WHO) announced coronavirus disease 2019 (COVID-19) had become a global pandemic on March 11, 2020, the number of infections has been increasing. The purpose of this meta-analysis was to investigate the prognosis of COVID-19 in patients with coronary heart disease., Method: Pubmed, Embase, and Cochrane Library databases were searched to collect the literature concerning coronary heart disease and COVID-19. The retrieval time was from inception to Nov 20, 2020, using Stata version 14.0 for meta-analysis., Results: A total of 22,148 patients from 40 studies were included. The meta-analysis revealed that coronary heart disease was associated with poor prognosis of COVID-19 (OR=3.42, 95%CI [2.83, 4.13], P  < 0.001). After subgroup analysis, coronary heart disease was found to be related to mortality (OR = 3.75, 95%CI [2.91, 4.82], P  < 0.001), severe/critical COVID-19 (OR = 3.23, 95%CI [2.19, 4.77], P  < 0.001), ICU admission (OR = 2.25, 95%CI [1.34, 3.79], P  = 0.002), disease progression (OR = 3.01, 95%CI [1.46, 6.22], P  = 0.003); Meta-regression showed that the association between coronary heart disease and poor prognosis of COVID-19 was affected by hypertension ( P  = 0.004), and subgroup analysis showed that compared with the proportion of hypertension >30% (OR = 2.85, 95%CI [2.33, 3.49]), the proportion of hypertension <30% (OR = 4.78, 95%CI [3.50, 6.51]) had a higher risk of poor prognosis., Conclusion: Coronary heart disease is a risk factor for poor prognosis in patients with COVID-19., (© 2021 Elsevier España, S.L.U.
