Recording surgical video is not new in medicine. But not many surgical residency programs in India have this facility. The coronavirus disease (COVID) pandemic made us search for new ways to progress ahead in our surgical careers. We present a way to record surgical videos and live stream them to a select audience comprising surgical residents and faculty, wherever they may be. This may become a standard of teaching once adopted by all top surgical residency programs across the country.

In this study, we report the complete genome sequence of Lactiplantibacillus plantarum L55, a probiotic strain of lactic acid bacteria isolated from kimchi. The genome consists of one circular chromosome (2,077,416 base pair [bp]) with a guanine cytosine (GC) content of 44.5%, and two circular plasmid sequences (54,267 and 19,592 bp, respectively). We also conducted a comprehensive analysis of the genome, which identified the presence of functional genes, genomic islands, and antibiotic-resistance genes. The genome sequence data presented in this study provide insights into the genetic basis of L. plantarum L55, which could be beneficial for the future development of probiotic applications.

Selenium (Se) is an essential trace mineral that plays an important role in physiological processes by regulating the antioxidant defense system and enhancing immunity. Chromium is an essential mineral involved in carbohydrate and lipid metabolism and also plays a role in maintaining normal insulin function. Based on these advantages, we hypothesized that the addition of selenomethionine (SeMet) and organic chromium (OC) to broiler diets would increase Se deposition, antioxidant capacity and immune response in meat. Therefore, this study analyzed the effects of OC and SeMet on growh performance, nutrients digestibility, blood profiles, intestinal morphology, meat quality characteristics, and taxonomic analysis of broilers. A total of 168 one-day-old broiler chicken (Arbor Acres) were randomly allotted to 3 groups based on the initial body weight of 37.33 ± 0.24 g with 7 replicate per 8 birds (mixed sex). The experiments period was 28 days. Dietary treatments were folloewd: Basal diets based on corn-soybean meal (CON), basal diet supplemented with 0.2 ppm OC and 0.2 ppm SeMet (CS4), and basal diet supplemented with 0.4 ppm OC and 0.4 ppm SeMet (CS8). Supplementation of OC and SeMet did not affect on growth performance, nutrient digestibility. However, CS8 supplementation increased in duodenum villus height and villus height : crypt depth, and increased in breast meat Se deposition. In addition, CS8 group showed higher uric acid and total antioxidant status than CON group. Taxonomic analysis at phylum level revealed that Proteobacteria and Firmicutes of CS4 and CS8 were lower than CON group. In genus level, the relative abundance of fecal Lactobacillus and Enterococcus of CS4 and CS8 groups were higher than CON group. In short, 0.4 ppm OC and 0.4 ppm SeMet supplementation to broiler diet supporitng positive gut microbiome change, also enhancing antioxidant capacity, and Se deposition in breast meat.

The PANTHEON (Performance of Currently Available traNscaTHEter Aortic Valve Platforms in Inoperable Patients With Pure Aortic regurgitatiON of a native valve) study examined transcatheter aortic valve replacement in patients with severe pure native aortic valve regurgitation. With a real-world dataset from 16 centres in Europe and the USA, the study encompassed 201 patients. The major complications included valve embolization or migration in 12.4%, moderate to severe aortic regurgitation in 9.5% cases and need for permanent pacemaker in 22.3% cases. Self-expanding and balloon-expandable devices demonstrated similar outcomes. Those experiencing valve embolization or migration had higher 1-year adverse event rates.
