These touchstones can help guide us in selecting patients who might benefit from the advanced imaging and invasive procedures that present enormous logistical challenges in the current context. Lacking a robust evidence base, pathophysiologic reasoning can help guide our choices of therapy for individual clinical scenarios. We must exercise caution and extreme humility, as often plausible interventions fail when tested rigorously. But act today we must, and understanding the multiplicity of mechanisms of myocardial injury in COVID-19 infection will help us meet our mission unsupported by the comfort of strong data. © 2020 Published by Elsevier on behalf of the American College of Cardiology Foundation.Introduction Breast radiotherapy accounts for a significant proportion of patient volume in contemporary radiation oncology practice. In the setting of anticipated resource constraints and widespread community infection with SARS-CoV-2 during the COVID-19 pandemic, measures for balancing both infectious and oncologic risk among patients and providers must be carefully considered. Here, we present evidence-based guidelines for omitting or abbreviating breast cancer radiotherapy, where appropriate, in an effort to mitigate risk to patients and optimize resource utilization. Methods Multidisciplinary breast cancer experts at a high-volume comprehensive cancer center convened contingency planning meetings over the early days of the COVID-19 pandemic to review the relevant literature and establish recommendations for the application of hypofractionated and abbreviated breast radiation regimens. Results Substantial evidence exists to support omitting radiation among certain favorable risk subgroups of breast cancer patients and for abbreviating or accelerating regimens among others. For those who require either whole-breast or post-mastectomy radiation, with or without coverage of the regional lymph nodes, a growing body of literature supports various hypofractionated approaches that appear safe and effective. Conclusion In the setting of a public health emergency with the potential to strain critical healthcare resources and place patients at infection risk, the parsimonious application of breast radiotherapy may alleviate a significant clinical burden without compromising long term oncologic outcomes. The judicious and personalized use of immature study data may be warranted in the setting of a competing mortality risk from this widespread pandemic. © 2020 The Author(s).Purpose During a global pandemic the benefit of routine visits and treatment of cancer patients must be weighed against the risks to patients, staff, and society. Prostate cancer is one of the most common cancers Radiation Oncology departments treat, and efficient resource utilization is essential in the setting of a pandemic. Herein, we aim to establish recommendations and a framework by which to evaluate prostate radiotherapy management decisions. Patients and Methods Radiation Oncologists from the United States and United Kingdom rapidly conducted a systematic review and agreed upon recommendations to safely manage prostate cancer patients during the COVID-19 pandemic. this website A RADS framework was created Remote visits, and Avoidance, Deferment, and Shortening of radiotherapy was applied to determine appropriate approaches. Results Recommendations are provided by National Comprehensive Cancer Network (NCCN) risk group, including clinical node positive, post-prostatectomy, oligometastatic, and low volume M1 diseasein a global pandemic. © 2020 The Author(s).Starting from Wuhan, China, SARS-CoV-2 has been a catastrophic epidemic involving many countries worldwide. After China, Italy has been heavily affected and severe measures to limit the spread have been taken in the last weeks. Radiation Oncology departments must guarantee optimal cancer treatments even in such a challenging scenario of an ongoing aggressive epidemic. Adopted preventive measures and recommendations are highlighted for patients, professionals and clinical operations to minimize the risk of infection while safely treating cancer patients. © 2020 The Authors.

Methods DMEK surgeries performed at two centers using a standardized technique were reviewed retrospectively for the occurrence of intraoperative fibrin formation. Cases were assessed for recipient medical history, donor age, best spectacle-corrected visual acuity (BSCVA), intraoperative unscrolling time, 6-month endothelial cell loss (ECL), and the course of the mate donor cornea. Results In this review of 868 cases of standardized DMEK surgery with surgical peripheral iridotomy, 32 eyes of 29 patients (3.7%) were complicated by the formation of intraoperative fibrin formation, including 3 patients that developed fibrin in both eyes. Three of the 32 grafts failed (9.4%). None of the mate corneas transplanted (n = 27) developed complications related to fibrin. The donor age ranged from 51 to 75 years and recipient age ranged from 49 to 82 years (median, 66 years). Unscrolling time ranged from 1 to 105 min (median, 15 min). Nine eyes required one rebubble procedure. No eyes had vision-limiting comorbidities, and the 6-month BSCVA was ≥20/40 in all eyes. Six-month ECL ranged from 19% to 73% (median, 44%). Conclusions We conclude that fibrin formation during DMEK surgery is an uncommon but important complication that can make graft manipulation more difficult, and may have deleterious effects on endothelial cell density and graft survival. © 2020 Published by Elsevier Inc.Purpose To present the case of a patient with Toric Lentis Mplus intraocular lens (IOL) (Oculentis, Berlin, Germany) opacification after vitrectomy and his follow-up. Observations A 44-year-old man with high myopia and right optic neuritis history complained of visual impairment due to cataract in the right eye. We performed uneventful phacoemulsification and implanted a Toric Lentis Mplus IOL in his right eye. Six months later, he came to us with a retinal detachment in the nasal area of the right eye. We performed a 25-gauge vitrectomy with gas tamponade and endolaser treatment. Ten months after the vitrectomy, he complained of blurred vision in the right eye again. On slit-lamp examination, we observed a wide opacification localized to the anterior surface of the IOL. We explanted the IOL from the right eye and replaced it with a Clareon IOL (Alcon, Fort Worth, TX). The explanted IOL was examined under light microscopy and scanning electron microscopy. Conclusions and importance We described a case of postoperative opacification of Toric Lentis Mplus IOL after vitrectomy.
