PurposeThe COVID-19 pandemic has impacted healthcare systems globally, little is known about the trauma patterns during a national lockdown. The aim of this study is to delineate the trauma patterns and outcomes at Aintree University Teaching Hospital level 1 Major Trauma Centre (MTC) during the COVID-19 lockdown imposed by the U.K. government.MethodsA retrospective cohort study data from the Merseyside and Cheshire Trauma Audit and Research Network database were analysed. The 7-week ‘lockdown period’ was compared to a 7-week period prior to the lockdown and also to an equivalent 7-week period corresponding to the previous year.ResultsA total of 488 patients were included in the study. Overall, there was 37.6% and 30.0% reduction in the number of traumatic injuries during lockdown. Road traffic collisions (RTC) reduced by 42.6% and 46.6%. RTC involving a car significantly reduced during lockdown, conversely, bike-related RTC significantly increased. No significant changes were noted in deliberate self-harm, trauma severity and crude mortality during lockdown. There was 1 mortality from COVID-19 infection in the lockdown cohort.ConclusionTrauma continues during lockdown, our MTC has continued to provide a full service during lockdown. However, trauma patterns have changed and departments should adapt to balance these alongside the COVID-19 pandemic. As the U.K. starts its cautious transition out of lockdown, trauma services are required to be flexible during changes in national social restrictions and changing trauma patterns. COVID-19 and lockdown state were found to have no significant impact on survival outcomes for trauma.

Acute pancreatitis (AP) is a debilitating, sometimes fatal disease, marked by local injury and systemic inflammation. Mitochondrial dysfunction is a central feature of pancreatic damage in AP, however, its involvement in circulating blood cell subtypes is unknown. This study compared mitochondrial bioenergetics in circulating leukocytes from AP patients and healthy volunteers: 15 patients with mild to severe AP were compared to 10 healthy controls. Monocytes, lymphocytes and neutrophils were isolated using magnetic activated cell sorting and mitochondrial bioenergetics profiles of the cell populations determined using a Seahorse XF24 flux analyser. Rates of oxygen consumption (OCR) and extracellular acidification (ECAR) under conditions of electron transport chain (ETC) inhibition (“stress” test) informed respiratory and glycolytic parameters, respectively. Phorbol ester stimulation was used to trigger the oxidative burst. Basal OCR in all blood cell subtypes was similar in AP patients and controls. However, maximal respiration and spare respiratory capacity of AP patient lymphocytes were decreased, indicating impairment of functional capacity. A diminished oxidative burst occurred in neutrophils from AP patients, compared to controls, whereas this was enhanced in both monocytes and lymphocytes. The data demonstrate important early alterations of bioenergetics in blood cell sub-populations from AP patients, which imply functional alterations linked to clinical disease progression.

In 1996, AT&T Corp. closed the sale AT&T Capital Corp. to management and Hercules Holding Ltd. The acquisition was followed, 2 weeks later, by the issue of approximately $3.2 billion of equipment-lease-backed-notes, approximately $1.2 billion of which was used to finance the acquisition. The transaction was unique in that it marked the first time a company has used proceeds from an asset-backed securitization to fund an acquisition or merger on such a large scale. The transaction's success also provided AT&T Capital with a new, large-scale financing alternative and is likely to have made equipment leasing a future mainstay of the asset-backed securitization market.
