Abstract Background Ceftriaxone (CTX) and penicillin G (PCN G) are considered reasonable treatment options for viridans group streptococci (VGS) bloodstream infections, but comparisons between these agents are limited. We evaluated clinical outcomes amongst patients treated with these agents for complicated VGS bacteremia. Methods This was a single-center, retrospective study of adult patients with ≥1 positive VGS blood culture who were treated with either CTX or PCN G/ampicillin (both included in PCN arm) between January 2013 and June 2019. The primary outcome was a composite of safety endpoints, including hospital readmission due to VGS bacteremia or adverse events (AE) from therapy, Clostridioides difficile infections, treatment modification or discontinuation due to AE from therapy, and development of extended-spectrum beta-lactamase resistance. Secondary outcomes included individual safety endpoints, VGS bacteremia recurrence, hospital readmission, and all-cause mortality. Results Of 328 patients screened, 94 met eligibility criteria (CTX n= 64, PCN n=30). Streptococcus mitis was the most common isolate and infective endocarditis was the predominant source of infection. CTX was not significantly associated with increased risk of the primary composite safety outcome (CTX 14% vs. PCN 27%; P= 0.139). The driver of the composite outcome was hospital readmission due to VGS bacteremia or therapy complications. No secondary endpoints differed significantly between groups. On multivariate analysis, source removal was a protective factor of the primary composite safety outcome. Conclusions Despite potential safety concerns with the prolonged use of CTX in complicated VGS bacteremia, this study did not demonstrate higher rates of treatment failure, adverse events, or resistance.

Abstract Background Viridans group streptococci (VGS) is an infrequent yet significant cause of bloodstream infections, and complicated cases may require prolonged antibiotic therapy. Ceftriaxone (CTX) and penicillin G (PCN G) are both considered first line options for VGS infections, but comparisons between these agents are limited. We evaluated the clinical outcomes amongst patients treated with CTX and PCN G for complicated VGS bacteremia. Methods This was a single-center, retrospective study of adult patients with ≥1 positive VGS blood culture who were treated with either CTX or PCN G/ampicillin (both included in PCN G arm) between January 2013 and June 2019. The primary outcome was a composite of safety endpoints, including hospital readmission due to VGS or an adverse event (AE) from therapy, Clostridioides difficile infections, treatment modification or discontinuation due to an antibiotic-related AE, and development of extended-spectrum beta lactamase resistance. Secondary outcomes included the individual safety endpoints, VGS bacteremia recurrence, hospital readmission, and all-cause mortality. Results Of 328 patients screened for inclusion, 94 patients met eligibility criteria (CTX n= 64, PCN G n=34). Median age was 68 years (IQR 56–81) and 68% were male. Study patients did not present with critical illness, as reflected by a median Pitt bacteremia score of 0 in the CTX and 1 in the PCN G arms, P=0.764. Streptococcus mitis was the most common VGS isolate and infective endocarditis (IE) was the predominant source of infection. CTX was not significantly associated with increased risk of the primary outcome (14% vs. 27%; P= 0.139). The driver of the composite outcome was hospital readmission due to VGS bacteremia or therapy complications. Results were similar in the subgroup of patients with IE (12.5% vs. 23.5%). No secondary endpoints differed significantly between groups. On multivariate analysis, source removal was a protective factor of the primary outcome (OR 0.1; 95% CI 0.020–0.6771; P= 0.017). Conclusion Despite potential safety concerns with the prolonged use of CTX in complicated VGS bacteremia, this study did not demonstrate a higher rate of treatment failure, adverse events, or resistance. These findings warrant further exploration. Disclosures All Authors: No reported disclosures

Abstract Background Shorter durations have shown similar clinical outcomes as longer durations for uncomplicated (source-controlled) Gram-negative bloodstream infections (BSI). There is limited data on the outcomes of patients with non-pneumococcal streptococcal BSI receiving shorter durations of therapy compared to usual durations. Methods This was a retrospective, multicenter study of adults hospitalized between January 2018 and March 2019 with ≥ 1 blood culture positive for Streptococcus spp. Exposed patients were those who received ≤ 10 days of antibiotics (i.e., short course therapy) and unexposed patients were those who received 11-21 days of antibiotics (i.e., prolonged course therapy). Patients were excluded if they had S. pneumoniae BSI, suspected contamination, did not receive or complete therapy, or treated for > 21 days. The primary outcome was a composite of recurrent bacteremia with the same pathogen, hospital readmission, or all-cause mortality, all within 30 days from completing therapy. The odds of achieving the primary outcome was compared between exposed and unexposed patients using multivariable logistic regression analysis. Results A total of 176 patients met eligibility criteria. 35 (20%) received a short course (median 8 days) and 141 (80%) received a prolonged course (median 15 days) of antibiotic therapy. Baseline characteristics were similar between short and long course groups. The most common pathogens were viridans group streptococci (22%) and S. agalactiae (23%). The most common BSI source was skin and soft tissue infection (SSTI) (40%). The primary outcome occurred in 26% (9/35) and 23% (33/141) of patients in the short course and prolonged course groups, respectively (p = 0.774). The proportion of patients in the short course and prolonged course groups who experienced recurrent BSI, hospital readmission, or all-cause mortality were also non-significant. After adjusting for receipt of an infectious diseases consult, Pitt bacteremia score, and SSTI source, the adjusted odds of meeting the composite outcome remained unchanged (aOR 1.41, 95% CI 0.55 – 3.61, p = 0.466).

Outcomes Conclusion Approximately a week of antibiotic therapy may be associated with similar clinical outcomes as longer antibiotics courses in patients with uncomplicated streptococcal BSI.

Abstract Background The relationship between sarcopenia and clinical outcomes outside of the post-operative setting has not been well-studied in IBD patients. We aimed to characterize the prevalence of sarcopenia and its association with adverse events and clinical response in IBD patients starting on new biologic medications. Methods We identified a retrospective cohort of adult (≥18 years old) IBD patients at the University of Minnesota with an abdominal CT or MRI within 6 months prior to or one month after starting a new biologic medication. Baseline demographics, disease severity (based on Physician’s Global Assessment from GI encounters), laboratory values and clinical outcomes for one year after the start of medications were obtained from chart review. The primary endpoint was incidence of adverse events (defined as infection, need for surgery, or hospitalization) within one year after medication start. The secondary outcome was clinical response as assessed based on clinical, endoscopic, and radiographic follow-up. Skeletal muscle index (SMI) measures were obtained from CT/MRI images at the L3 vertebral level. Published cut-offs (SMI of 38.5 cm2/m2 for women and 52.4 cm2/m2 for men) were used to determine the presence of sarcopenia. Associations between sarcopenia and outcomes were analyzed using logistic regression and age stratification was performed. Results Ninety-four patients (74 CD, 20 UC, 47% male, mean age 38 years) were included in the analysis. The majority of patients had moderate disease severity or worse (83%) at the time of medication start, and 75% were started on anti-TNF medications. Overall prevalence of sarcopenia was 57% (57% CD, 60% UC). In the entire cohort, sarcopenia was not associated with increased rates of adverse events (OR = 0.516, 95% CI 0.217–1.225; p= 0.1334). However, in patients ≥ 50 years of age (n=23), those with sarcopenia had higher risk of infection at 1 year compared to those without sarcopenia (85% vs. 20%; OR = 21.99, 95% CI 3.086–262.515; p = 0.0051). The majority of infections were those that required antibiotics or antivirals, but not hospitalization. Examples included sinusitis, upper respiratory infections, periodontitis, urinary tract infection, herpes simplex, and two cases of C. difficile. Furthermore, when controlling for disease duration and concomitant steroid use, the association between sarcopenia and infection remained significant. In this age subgroup, there was no association between sarcopenia and clinical response to therapy. Conclusions In our cohort, sarcopenia was present in the majority of adult IBD patients starting new biologic medications. In patients ≥ 50 years old, sarcopenia was associated with an increased risk of infections. Further work is needed to validate these findings and to understand which patients may benefit from sarcopenia assessment prior to biologic start.

Abstract Aims The aim of this study was to establish whether patients with multiple comorbidities may be at elevated risk of hyperkalaemia (HK), a potentially life-threatening electrolyte imbalance, and the associated adverse clinical outcomes. Methods and results This was a retrospective, observational cohort study using UK primary and secondary care data. Adult patients with at least one of: resistant hypertension, chronic kidney disease stage 3+, dialysis, heart failure (HF), and diabetes, were eligible for inclusion. According to their diagnoses, patients were grouped into overlapping cohorts that were updated as multimorbidity progressed. Outcomes of interest were incident HK, all-cause mortality (ACM), and major adverse cardiovascular events (MACE). A total of 673 686 patients met the eligibility criteria, 36.3% of whom developed multimorbidity during the study period. A consistent U-shaped association was observed between serum K+ level and adjusted incidence of ACM and MACE. Hyperkalaemia was progressively more common with increasing Charlson Comorbidity Index (CCI). Relative to a CCI <3, scores of ≥3 to <6, and ≥6 were associated with 2.9- and 6.2-fold increases, respectively, in crude HK (serum K+ ≥5.0 mmol/L) incidence rate. In all condition-based cohorts except for HF, there was a clear correlation between increasing CCI and the risk of ACM and MACE associated with hypokalaemia and HK. Conclusion Patients with a higher CCI are at an increased risk of developing HK and appear more prone to adverse clinical outcomes associated with abnormal serum K+ levels, warranting additional routine clinical monitoring.

Abstract Funding Acknowledgements Type of funding sources: Foundation. Main funding source(s): Beijing Municipal Health Commission (Grant number: 2020-1-4032). Background Whether the underlying risk of high bleeding risk (HBR) influences the relationship of high ischemic risk (HIR) features with adverse events after drug-eluting stent implantation remains unclear. The purpose of this study was to evaluate (1) the prognostic effect of ESC guideline-endorsed HIR features on long-term clinical outcomes and (2) whether the outcomes of HIR versus non-HIR features vary by HBR status. Methods Ten thousand one hundred sixty-seven consecutive patients who underwent percutaneous coronary intervention between January 2013 and December 2013 were prospectively enrolled in Fuwai PCI Registry. Patients who are at HIR were defined as: diffuse multivessel disease in diabetic patients, chronic kidney disease, at least three stents implanted, at least three stents lesions treated, bifurcation with two stents implanted, total stent length > 60 mm, or treatment of chronic total occlusion. The definition of HBR was based on the Academic Research Consortium (ARC) for HBR criteria. The primary ischemic outcome was major adverse cardiac event (MACE), a composite of cardiac death, myocardial infarction, target vessel revascularization and stent thrombosis. The primary bleeding outcome was clinically relevant bleeding, defined according to Bleeding Academic Research Consortium (BARC) type 2, 3 or 5 bleeding. Results With a 2.4-year median follow-up, 4430 patients (43.6%) having HIR experienced a significantly higher risk of MACE (hazard ratio [HR] adjust : 1.56, 95% confidence interval [CI]: 1.34–1.82; P < 0.001) and device-oriented composite endpoint (composite of cardiac death, target-vessel MI, and target lesion revascularization) (HRadjust : 1.52 [1.27–1.83]; P < 0.001), compared to those having non-HIR. The risk of clinically relevant bleeding did not differ between groups (HRadjust : 0.85 [0.66–1.08]; P = 0.174). Associations between HIR and adverse events were similar in HBR and non-HBR groups, without evidence of interaction (all P interaction > 0.05); however, adverse event rates were highest among subjects with both HIR and HBR. Conclusions ESC guideline-endorsed HIR was associated with significantly increased risk of MACE without any significant differences in clinically relevant bleeding. The presence of ARC-HBR does not emerge as a modifier of cardiovascular risk for patients at HIR, suggesting more potent and longer antiplatelet therapy may be beneficial for this patient population.

Abstract Background Apolipoproteins (Apo) are known atherogenic factors that play important roles in many mechanisms related to coronary heart disease (CHD). However, it is unclear whether the apoB/apoA1 ratio is an equal or a better predictor than the Framingham Risk Score or TC/HDL-c for predicting clinical outcomes in patients undergoing percutaneous coronary intervention. Methods We investigated the association between Apolipoprotein B/A1 ratio and cardiovascular risk factors as well as the severity of CHD in 2256 Han Chinese patients. The potential of Apolipoprotein B/A1 ratio, Framingham Risk Score and TC/HDL-c were assessed as a marker to predict cardiovascular adverse events in a prospective subgroup of 1639 CHD patients during a 5-year follow-up. Results In the multivariate model, adjusted odds ratios (ORs) were significant for 3-VD vs. 1-VD (OR = 2.36; 95% CI: 1.65–3.38, for the fourth vs. first quartile; Ptrend < 0.001). The subgroup analysis showed that patients with a higher ApoB/ApoA1 ratio had an increased risk of developing multi-branch lesions and potentially suffer more cardiovascular adverse events (anginas, myocardial infarctions, heart failures, strokes, and cardiac deaths) in the future (adjusted HR =1.92; 95% CI: 1.10–3.13, for the fourth vs. first quartile). In the ROC analysis, the AUC for ApoB/A1 ratio was larger than that of Framingham Risk Score (0.604 vs. 0.543, p = 0.01) and TC/HDL-c (0.604 vs. 0.525, p < 0.01). Conclusion Our results suggest a significant association between ApoB/ApoA1 ratio and CHD severity and cardiovascular outcomes among patients with existing CHD and ApoB/A1 ratio demonstrated a better predictive accuracy for clinical outcomes compared with Framingham Risk Score and TC/HDL-c.

ABSTRACTAcinetobacter baumanniihas become a leading cause of bloodstream infections (BSI) in health care settings. Although the incidence of infection with carbapenem- and ampicillin-sulbactam-resistant (CASR)A. baumanniihas increased, there is a scarcity of studies which investigate BSI caused by CASRA. baumannii. A retrospective cohort study was conducted on adult patients with BSI caused byA. baumanniiand who were admitted to the Detroit Medical Center between January 2006 and April 2009. Medical records were queried for patients' demographics, antimicrobial exposures, comorbidities, hospital stay, and clinical outcomes. Bivariate analyses and logistic regression were employed in the study. Two hundred seventy-four patients with BSI caused byA. baumanniiwere included in the study: 68 (25%) caused by CASRA. baumanniiand 206 (75%) caused by non-CASRA. baumannii. In multivariate analysis, factors associated with BSI caused by CASRA. baumanniiincluded admission with a rapidly fatal condition (odds ratio [OR] = 2.83, 95% confidence interval [CI] = 1.27 to 6.32,Pvalue = 0.01) and prior use of antimicrobials (OR = 2.83, 95% CI = 1.18 to 6.78,Pvalue = 0.02). In-hospital mortality rates for BSI caused by CASRA. baumanniiwere significantly higher than those for non-CASRA. baumannii-induced BSI (43% versus 20%; OR = 3.0, 95% CI = 1.60 to 5.23,Pvalue < 0.001). However, after adjusting for potential confounders, the association between BSI caused by CASRA. baumanniiand increased risk of in-hospital mortality was not significant (OR = 1.15, 95% CI = 0.51 to 2.63,Pvalue = 0.74). This study demonstrated that CASRA. baumanniihad a distinct epidemiology compared to more susceptibleA. baumanniistrains; however, clinical outcomes were similar for the two groups. Admission with a rapidly fatal condition was an independent predictor for both CASRA. baumanniiand in-hospital mortality.

Background: Environmental enrichment involves organisation of the environment and provision of equipment to facilitate engagement in physical, cognitive and social activity. In animals with stroke, it promotes brain plasticity and recovery. Aims: To assess the feasibility and safety of a patient-driven model of environmental enrichment incorporating access to communal and individual environmental enrichment. Methods: A non-randomised cluster trial with blinded measurement involving people with stroke (n=193) in 4 rehabilitation units was carried out. Feasibility was operationalised as activity 10 days after admission to rehabilitation and availability of environmental enrichment. Safety was measured as falls and serious adverse events. Benefit was measured as clinical outcomes at 3 months, by an assessor blinded to group. Results: The experimental group (n=91) spent 7% (95% CI -14 to 0) less time inactive, 9% (95% CI 0 to 19) more time physically, and 6% (95% CI 2 to 10) more time socially active than the control group (n=102). Communal environmental enrichment was available 100% of the time, but individual environmental enrichment was rarely within reach (24%) or sight (39%). There were no between-group differences in serious adverse events or falls at discharge or 3 months nor in clinical outcomes at 3 months. Conclusions: This patient-driven model of environmental enrichment was feasible and safe. However, the very modest increase in activity by people with stroke, and the lack of benefit in clinical outcomes 3 months after stroke do not provide justification for an efficacy trial.

ObjectiveThe aim of this paper is to describe evolution, epidemiology and clinical outcomes of COVID-19 in subjects tested at or admitted to hospitals in North West London.DesignObservational cohort study.SettingLondon North West Healthcare NHS Trust (LNWH).ParticipantsPatients tested and/or admitted for COVID-19 at LNWH during March and April 2020Main outcome measuresDescriptive and analytical epidemiology of demographic and clinical outcomes (intensive care unit (ICU) admission, mechanical ventilation and mortality) of those who tested positive for COVID-19.ResultsThe outbreak began in the first week of March 2020 and reached a peak by the end of March and first week of April. In the study period, 6183 tests were performed in on 4981 people. Of the 2086 laboratory confirmed COVID-19 cases, 1901 were admitted to hospital. Older age group, men and those of black or Asian minority ethnic (BAME) group were predominantly affected (p<0.05). These groups also had more severe infection resulting in ICU admission and need for mechanical ventilation (p<0.05). However, in a multivariate analysis, only increasing age was independently associated with increased risk of death (p<0.05). Mortality rate was 26.9% in hospitalised patients.ConclusionThe findings confirm that men, BAME and older population were most commonly and severely affected groups. Only older age was independently associated with mortality.
