RESUMEN
INTRODUCTION: Patients with diabetes mellitus admitted to hospital with COVID-19 have poorer outcomes. However, the drivers of poorer outcomes are not fully elucidated. We performed detailed characterization of patients with COVID-19 to determine the clinical and biochemical factors that may be drivers of poorer outcomes. RESEARCH DESIGN AND METHODS: This is a retrospective cohort study of 889 consecutive inpatients diagnosed with COVID-19 between March 9 and April 22, 2020 in a large London National Health Service Trust. Unbiased multivariate logistic regression analysis was performed to determine variables that were independently and significantly associated with increased risk of death and/or intensive care unit (ICU) admission within 30 days of COVID-19 diagnosis. RESULTS: 62% of patients in our cohort were of non-white ethnic background and the prevalence of diabetes was 38%. 323 (36%) patients met the primary outcome of death/admission to the ICU within 30 days of COVID-19 diagnosis. Male gender, lower platelet count, advancing age and higher Clinical Frailty Scale (CFS) score (but not diabetes) independently predicted poor outcomes on multivariate analysis. Antiplatelet medication was associated with a lower risk of death/ICU admission. Factors that were significantly and independently associated with poorer outcomes in patients with diabetes were coexisting ischemic heart disease, increasing age and lower platelet count. CONCLUSIONS: In this large study of a diverse patient population, comorbidity (ie, diabetes with ischemic heart disease; increasing CFS score in older patients) was a major determinant of poor outcomes with COVID-19. Antiplatelet medication should be evaluated in randomized clinical trials among high-risk patient groups.

BACKGROUND: Over 6000 people are on the United Kingdom organ transplant waiting list, and approximately three people die each day due to a lack of donors. Social deprivation status has been shown to affect registration. The aim of this study was to evaluate the effectiveness of school level education at increasing awareness of the issues surrounding organ donation and organ donor registration, and the effect of socioeconomic deprivation and age has on these outcomes. METHODS: A 15-minute presentation about organ donation and the issues in transplantation was given to secondary school students from the United Kingdom. An optional questionnaire was then distributed. RESULTS: 1155 paper questionnaires were completed from nine schools. The average age was 15.5 (SD = 0.5) years. Before the presentation, 10% of students were on the ODR. Following the presentation, the number of students who were on the ODR or planned to join significantly increased to 56%, independent of age (P < 0.0001). Similarly, there was a significant increase in Likert scores for awareness of the issues in transplantation, independent of age (P < 0.0001). CONCLUSIONS: This early educational presentation significantly increased awareness of the issues in transplantation and planned organ donor registration, independent of age and deprivation.

The role of patient-specific (PS) technology in total hip arthroplasty remains relatively unexplored. We asked whether PS guides: (1) Reduced average surgical errors? (2) Reduced outlier error frequencies? (3) Could predict the size of implants used? A single surgeon implanted femurs using either standard or PS guides and was blinded to the pre-operative plans. There were significant differences in median leg length errors between standard (3.3 mm) and PS groups (1.4 mm), U = 110, z = -2.3, p = 0.02. In contrast to the PS group, the standard group had significantly more outlier errors and frequently undersized implants. PS guides improve hip arthroplasty surgical accuracy.Abbreviations: PS: patient specific; THA: total hip arthroplasty; LLD: leg length discrepancies; HRA: hip resurfacing arthroplasty.
