Safety and feasibility of robotic assisted percutaneous coronary intervention compared to standard percutaneous coronary intervention- a systematic review and meta-analysis.

OBJECTIVE: Robotically assisted PCI offers a great alternative to S-PCI. This has gained even more relevance during the COVID-19 pandemic era however safety of R-PCI compared to S-PCI has not been studied well. This study explores the safety and efficacy of robotically assisted PCI (R-PCI) compared to standard PCI (S-PCI) for the treatment of coronary artery disease (CAD). METHODS: PubMed, Scopus, Ovid, and Google scholar databases were searched for studies comparing R-PCI to S-PCI. Outcomes included clinical success, procedure time, fluoroscopy time, contrast use and radiation exposure. RESULTS: Theauthors included 5 studies comprising 1555 patients in this meta-analysis. Clinical success was comparable in both arms (p = 0.91). Procedure time was significantly longer in R-PCI group (risk ratio: 5.52, 95% confidence interval: 1.85 to 9.91, p = 0.003). Compared to S-PCI, patients in R-PCI group had lower contrast use (meandifference: -19.88, 95% confidence interval: -21.43 to -18.33, p < 0.001), fluoroscopy time (mean difference:-1.82, 95% confidence interval: -3.64 to -0.00, p = 0.05) and radiation exposure (mean difference:-457.8, 95% confidence interval: -707.14 to -208.14, p < 0.001). CONCLUSION: R-PCI can achieve similar success as S-PCI at the expense of longer procedural times. However, radiation exposure and contrast exposure were lower in the R-PCI arm.

Emerging challenges of air pollution and particulate matter in China, India, and Pakistan and mitigating solutions.

This study examines point and non-point sources of air pollution and particulate matter and their associated socioeconomic and health impacts in South Asian countries, primarily India, China, and Pakistan. The legislative frameworks, policy gaps, and targeted solutions are also scrutinized. The major cities in these countries have surpassed the permissible limits defined by WHO for sulfur dioxide, carbon monoxide, particulate matter, and nitrogen dioxide. As a result, they are facing widespread health problems, disabilities, and causalities at extreme events. Populations in these countries are comparatively more prone to air pollution effects because they spend more time in the open air, increasing their likelihood of exposure to air pollutants. The elevated level of air pollutants and their long-term exposure increases the susceptibility to several chronic/acute diseases, i.e., obstructive pulmonary diseases, acute respiratory distress, chronic bronchitis, and emphysema. More in-depth spatial-temporal air pollution monitoring studies in China, India, and Pakistan are recommended. The study findings suggest that policymakers at the local, national, and regional levels should devise targeted policies by considering all the relevant parameters, including the country's economic status, local meteorological conditions, industrial interests, public lifestyle, and national literacy rate. This approach will also help design and implement more efficient policies which are less likely to fail when brought into practice.
