Results Paired comparison of pre and post-HBCR using Wilcoxon signed-rank test revealed a statistically significant difference in the pre and post-HBCR scores for DASI, DASI-Mets, and SF-36 physical functioning (p values 0.05, 0.034, and 0.016, respectively), suggesting an improvement in the patients' physical functioning after participating in the HBCR program. Conclusions In conclusion, our pilot study offers novel insight into the role of HBCR in improving physical health and well-being in post-TAVR patients while eliminating the barriers of transportation and access to cardiac rehabilitation programs.The ongoing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has profoundly impacted all fields of medicine. Infection with SARS-CoV-2 and the resulting coronavirus of 2019 (COVID-19) syndrome has multiorgan effects. The pandemic has united researchers from bench to bedside in attempts to understand the pathophysiology of the disease and define optimal treatment strategies. Cardiovascular disease is highly prevalent and a leading cause of death across gender, race, and ethnic groups. As the pandemic spreads, there is increasing concern about the cardiovascular effects of the viral infection and the interaction of infection with existing cardiovascular disease. Additionally, there are concerns about the cardiac effects of the numerous treatment agents under study. It will be essential for cardiologists to understand the interplay between underlying cardiac comorbidities, acute cardiovascular effects of COVID-19 disease, and adverse effects of new treatments. Here we describe emerging evidence of the epidemiology of SARS-CoV-2 infection and underlying cardiovascular disease, the evidence for direct myocardial injury in SARS-CoV-2 infection, the specific presentations of cardiovascular involvement by SARS-CoV-2, and the cardiac effects of emerging treatments.Purpose The aim of this study is to compare the long-term follow-up outcomes of traditional and accelerated corneal cross-linking (CXL) for keratoconus. Methods This retrospective comparative cohort study included patients with keratoconus who underwent corneal cross-linking (CXL) between August 2008 and December 2016. Patients treated before August 2013 underwent the traditional Dresden protocol, and those treated subsequently received the accelerated protocol, i.e., 0.1% riboflavin soaking for 10 min, followed by pulsed UV-A irradiation at 30 mW/cm2 for 8 min, and a total irradiation power of 7.2 J/cm2. The primary outcome was the success rate in halting the disease progression. The postoperative changes in visual acuity, keratometry readings, endothelial cell count and complications following accelerated CXL and conventional CXL were compared. ABBV-075 mw Results This study evaluated 113 eyes over a mean follow-up period of 37.61 ± 16.34 months. It was found that 89.6% and 95.7% of the eyes were successfully treated with the traditional and accelerated protocols, respectively (p = 0.239). The corrected-distance visual acuity improved in both groups, but it was significantly better following the accelerated protocol (p = 0.037). Traditional protocol group had more postoperative complications than the accelerated group (8.9% versus 2%), although not reaching statistically significant difference (p = 0.142). There were no significant differences in the topographic (p = 0.122) and refractive (p = 0.570) outcomes. Conclusion Accelerated CXL and conventional CXL are both safe and effective, and the long-term follow-up showed that the accelerated protocol was similar to the standard one in terms of halting keratoconus and achieving visual outcomes. Because of its potential benefits, the accelerated protocol may be considered for the treatment of progressive keratoconus.Purpose To evaluate one-year visual, refractive, and topographic outcomes of 58 eyes of 53 keratoconus patients who underwent surgery with a progressive thickness intrastromal corneal ring segment (ICRS). Methods This multi-center, retrospective, observational study evaluates the one-year effects of progressive thickness ICRS implanted in keratoconus patients meeting the inclusion criteria. One or two progressive ICRS were implanted in the selected eyes after creating an intrastromal tunnel with a femtosecond laser. Pre- and postoperative uncorrected distance visual acuity, best-corrected distance visual acuity, manifest refraction (both spherical equivalent and cylindrical refractions), corneal astigmatism, maximum keratometry, corneal thickness, and corneal topography measurements and indices were evaluated. Results In this retrospective case series, 58 eyes of 53 keratoconus patients were included with a follow-up of 12 months. The mean age was 30.89 ± 11.90 years. There were improvements postoperatively in mean values of visual acuities, both uncorrected from 0.71 (preoperatively) to 0.28 (log MAR), and best-corrected from 0.28 to 0.10 (log MAR), mean cylindrical refraction from - 2.35 ± 1.51 to - 4.15 ± 2.23 D, and mean spherical equivalent from - 2.10 ± 2.25 to - 4.64 ± 3.2 D. There was also a reduction in maximal keratometry from 54.21 D preoperatively to 50.93 D postoperatively. Conclusion The implantation of the progressive thickness ICRS is an effective and safe method to improve the vision of keratoconic eyes. Corneal stability was maintained at the 12-month mark.Purpose MTA apical plug approach is considered the gold standard in managing immature teeth with necrotic pulp tissues but does not increase root dimensions. Regenerative Endodontic Therapy (RET) has been advocated as an alternative technique for management of these teeth. This study aimed to assess the knowledge, experience and the opinions of dentists treating paediatric patients in the European and Arabian regions on RET. Methods A cross-sectional, pre-piloted 23-item self-administered questionnaire survey was distributed electronically using the Bristol Online Survey tool through the mailing list of the European Academy of Paediatric Dentistry, the Arabian Academy of Paediatric Dentistry's and the Egyptian Society of Paediatric Dentistry. Results 308 respondents completed the survey. Approximately half practised RET (N = 158; 51.3%), which was most frequently used to manage non-vital traumatized teeth. Majority of RET practitioners worked in university or dental institute practices. Protocol differences with deviation from the current published RET guidelines were observed.
