Coronavirus Disease 2019 and Catheterisation Laboratory Considerations: “Looking for Essentials”
The current coronavirus disease 2019 (COVID-19) outbreak is a significant health crisis that impacts every healthcare system worldwide, and has led to a dramatic change in dealing with different diseases during the pandemic. Interventional cardiologists are frontline workers who deal with many cardiovascular emergencies, either in patients with proven COVID-19 or in suspected cases. Many heart associations worldwide are currently setting appropriate recommendations for the management of emergency cardiac interventions. In this expert opinion, the authors highlight the essential requirements in the cardiac catheterisation laboratory during the COVID-19 pandemic

Photosynthetic Parameters and Oxidative Stress during Acclimation of Crepe-Myrtle (Lagerstroemia speciosa (L.) Pers.) in a meta-Topolin-Based Micropropagation System and Genetic Fidelity of Regenerated Plants
An improved and stable micropropagation system using the cytokinin, meta-Topolin (N6 (3-hydroxybenzylamino purine—mT), with nodal explants in Lagerstroemia speciosa L. was established. Among the different doses of mT, the maximum number of shoots with the highest shoot length was obtained using Murashige and Skoog’s (MS) medium supplemented with 5.0 µM mT. The results were consistent throughout the proliferation period, when recorded at week 4, 8, and 12 of being cultured, with an average of 16.4 shoots per nodal explant, and having a mean length of 4.10 cm at week 8. Shoot proliferation rates could be further improved by a combination of 5.0 µM mT with 0.5 µM α-naphthalene acetic acid in MS medium; nodal explants produced an average of 24.3 shoots with a mean length of 5.74 cm after 8 weeks of being cultured. Among the five different concentrations of three auxins tested for the rooting of microshoots in MS medium, a 1.0 µM indole-3-butyric acid treatment was the best, with an average of 10.3 roots per microshoot at an average length of 3.56 cm in 93% of microshoots within 4 weeks of being transferred to this medium. A significant reduction of both chlorophyll a and b in leaves during the first week of acclimation corresponded with a high accumulation of malondialdehyde (MDH), indicating that lipid peroxidation affected chlorophyll pigments. From the second week of acclimation, photosynthetic pigment content significantly increased and MDH content decreased. The net photosynthetic rate and leaf carotenoid content showed almost linear increases throughout the acclimation period. Activity of antioxidant enzymes, namely, superoxide dismutase, catalase, and peroxidases, consistently increased throughout the acclimation period, corresponding with the accumulation of photosynthetic pigments, thus demonstrating the role of the improved antioxidant enzymatic defense system during acclimation. A comparison of parent plant DNA with that of the greenhouse acclimated plants using random amplified polymorphic DNA and inter-simple sequence repeat markers showed a monomorphic pattern indicating genetic stability and the suitability of the method for micropropagation of L. speciosa

Women leaders in Cardiology. Contemporary profile of the WHO European region
AIMS: Women’s participation is steadily growing in medical schools, but they are still not sufficiently represented in cardiology, particularly in cardiology leadership positions. We present the contemporary distribution of women leaders in cardiology departments in the World Health Organization European region. METHODS AND RESULTS: Between August and December 2020, we applied purposive sampling to collect data and analyse gender distribution of heads of cardiology department in university/third level hospitals in 23 countries: Austria, Azerbaijan, Belgium, Bosnia-Herzegovina, Croatia, France, Germany, Greece, Italy, North Macedonia, Morocco, Poland, Portugal, Russia, Serbia, Slovakia, Slovenia, Spain, Switzerland, Tunisia, Turkey, Ukraine, and the UK. Age, cardiology subspecialty, and number of scientific publications were recorded for a subgroup of cardiology leaders for whom data were available. A total of 849 cardiology departments were analysed. Women leaders were only 30% (254/849) and were younger than their men counterpart (♀ 52.2 ± 7.7 years old vs. ♂ 58.1 ± 7.6 years old, P = 0.00001). Most women leaders were non-interventional experts (♀ 82% vs. ♂ 46%, P < 0.00001) and had significantly fewer scientific publications than men {♀ 16 [interquartile range (IQR) 2–41] publications vs. ♂ 44 (IQR 9–175) publications, P < 0.00001}. CONCLUSION: Across the World Health Organization European region, there is a significant gender disparity in cardiology leadership positions. Fostering a diverse and inclusive workplace is a priority to achieve the full potential and leverage the full talents of both women and men
