We have previously shown significant pathology in the heart and kidney of murine hematopoietic-acute radiation syndrome (H-ARS) survivors of 8.7-9.0 Gy total-body irradiation (TBI). The goal of this study was to determine temporal relationships in the development of vasculopathy and the progression of renal and cardiovascular delayed effects of acute radiation exposure (DEARE) at TBI doses less than 9 Gy and to elucidate the potential roles of senescence, inflammation and oxidative stress. Our results show significant loss of endothelial cells in coronary arteries by 4 months post-TBI (8.53 or 8.72 Gy of gamma radiation). This loss precedes renal dysfunction and interstitial fibrosis and progresses to abnormalities in the arterial media and adventitia and loss of coronary arterioles. Major differences in radiation-induced pathobiology exist between the heart and kidney in terms of vasculopathy progression and also in indices of inflammation, senescence and oxidative imbalance. The results of this work suggest a need for different medical countermeasures for multiple targets in different organs and at various times after acute radiation injury to prevent the progression of DEARE.

BackgroundThe COVID-19 pandemic has impacted GPs immensely. Work patterns have changed, risk stratification has been proposed, and the mental health of clinicians has been adversely affected. The COVID-19 prevalence among GPs is unknown. This study focuses on assessing the impact of COVID-19 on GPs in Leicestershire, the first UK city to lock down locally.AimThis survey assessed the prevalence of COVID-19 in GPs and explored GP work patterns in comparison with national guidance. It used a validated perceived stress tool to evaluate the impact of COVID-19 on GP stress perception.Design & settingThe cross-sectional retrospective survey was sent to all the GPs in Leicestershire.MethodA total of 111 GPs in Leicestershire took part voluntarily in an anonymised questionnaire-based study. A 29-item survey using SmartSurvey software was designed with multiple choice and Likert response scale questions.ResultsCOVID-19 prevalence in GPs in Leicestershire was 8.1%; 70.3% of GPs were of Black, Asian, and minority ethnic (BAME) origin; 91.9% of GPs had undergone risk stratification; and 79.3% of GPs felt supported by their practice, but only 59.5% felt supported with mental health. GPs described feeling more stressed during the COVID-19 pandemic than they had been previously.ConclusionThis is the first study evaluating COVID-19 prevalence among GPs in Leicestershire. Despite government interventions, GPs felt less supported with their mental health compared with pre-COVID-19 times. Thus, the NHS in England should focus on GP stress and wellbeing as they work towards the restoration and recovery of primary care while battling the second wave.

The birth of the COVID-19 pandemic has transformed working lives of British Asian general practitioners (GPs), such as one of the authors. The effects of the national lockdown and the subsequent loneliness have impacted every aspect of our lives and increased mental health problems. The added social isolation of local lockdowns, such as in Leicester, will undoubtedly exacerbate some health problems due to a lack of patient willingness to attend healthcare services and the postponement of some appointments. The lack of culturally competent support is likely to add to the isolation in non-English-speaking people. Thus, we should preempt these issues in a culturally effective manner. To prepare for subsequent waves, GPs are risk-stratifying patients for COVID-19 and have commenced ReSPECT care-plan conversations with higher-risk patients. But with the increased risk from COVID-19 to Black, Asian and minority ethnic patients, should this and other groups of patients also have a ReSPECT care plan? Is now the time to consider community-hospice settings for our palliative COVID-19 patients? This pandemic has uncovered a training need for healthcare professionals to feel more comfortable in discussing end of life as an integral consultation component. We should focus our efforts in alleviating suffering by achieving 'shared understanding' and 'negotiating management' of our ReSPECT conversations.
