Background The B-MaP-C study aimed to determine alterations to breast cancer (BC) management during the peak transmission period of the UK COVID-19 pandemic and the potential impact of these treatment decisions.Methods This was a national cohort study of patients with early BC undergoing multidisciplinary team (MDT)-guided treatment recommendations during the pandemic, designated ‘standard’ or ‘COVID-altered’, in the preoperative, operative and post-operative setting.Findings Of 3776 patients (from 64 UK units) in the study, 2246 (59%) had ‘COVID-altered’ management. ‘Bridging’ endocrine therapy was used (n = 951) where theatre capacity was reduced. There was increasing access to COVID-19 low-risk theatres during the study period (59%). In line with national guidance, immediate breast reconstruction was avoided (n = 299). Where adjuvant chemotherapy was omitted (n = 81), the median benefit was only 3% (IQR 2–9%) using ‘NHS Predict’. There was the rapid adoption of new evidence-based hypofractionated radiotherapy (n = 781, from 46 units). Only 14 patients (1%) tested positive for SARS-CoV-2 during their treatment journey.Conclusions The majority of ‘COVID-altered’ management decisions were largely in line with pre-COVID evidence-based guidelines, implying that breast cancer survival outcomes are unlikely to be negatively impacted by the pandemic. However, in this study, the potential impact of delays to BC presentation or diagnosis remains unknown.Subject terms: Breast cancer, Surgical oncology, Health care economics, Quality of life, Health policy 相似文献

The commonly used technique to facilitate intracardiac exposure during transatrial repair of tetralogy of fallot involves considerable retraction of the tricuspid valve using retractors. We describe an alternative surgical technique in which it is possible to dispense away with the retractors. The advantages of such a technique are discussed. 相似文献

Raghib syndrome is a rare developmental complex consisting of termination of the left superior vena cava in the left atrium, absence of the coronary sinus, and an atrial septal defect commonly located at the posterior‐inferior angle of the atrial septum. This complex was considered unique to Raghib syndrome; however, cases with a normal atrial septum have been reported where the orifice of the unroofed coronary sinus functions as the inter‐atrial communication. Our patient demonstrated an isolated persistent left superior vena cava draining into the left atrium through unroofed coronary sinus and presence of ostium primum atrial septal defect. 相似文献

There continues to be controversy on the long‐term effects of a patent ductus arteriosus (PDA) and its management. However, the hemodynamic effects of a large PDA in a preterm infant are well known. This article aims to provide insight into the adaptive changes and remodeling effects of a PDA on the myocardium in preterm infants. 相似文献

Wound inflammation is a rapid and highly orchestrated process that significantly impacts the wound healing cascade. Consequent to injury, a series of events set off that include inflammatory, proliferation and maturation phases leading to wound closure and restoration of normal skin integrity. Stimuli causing stress to host immune system or induce inflammatory response include tissue damage and pathogenic microbial infection.Several evidences points towards the positive role of inflammation as it essential to fight against the attack of invading pathogens and to remove dead tissues from the site of injury. Besides its positive role, prolonged inflammation is injurious and may result in deregulated stages of the wound healing which may lead to excessive scarring. Achieving balance in inflammatory cascade is one of the challenging tasks for development of a wound healing drug.This review mainly focuses on the pharmacological control of inflammation by agents which critically balance the inflammatory cascade. However, none of the agent is available in the healthcare market which exclusively plays a role in wound repair. In this review we shall explore different factors or agents affecting inflammation in wound healing. This information might be helpful in designing and development new process, technologies or drugs for better management of wound care. In addition, understanding the effect of inflammation on the outcome of the healing process will serve as a significant milestone in the area of pathological tissue repair. 相似文献
