Objective: Safety and efficacy of ECG-guided PICC insertion using a new silicon catheter with a conductive tip was evaluated in daily practice. Methods: A retrospective study was conducted on 1659 patients who accepted successful tip-conductive PICC placement and clinically followed-up until the catheter removal between January 2018 and April 2019. Baseline of patient characteristics, catheter placement characteristics, date of dressing changes as well as records of catheter-related complications were extracted from a special designed mobile APP. Results: The first-attempt success (success of placing catheter tip to the ideal position by primary indwelling operation) rate of PICC placement was 99.3%. The average duration of PICC placement was 128.7 ± 39.5 days and 1535 patients (92.5%) reached the therapy end-point without any complications and removed the catheter normally. The cumulative rates of total complications were 7.5%, including exit site infection (2.5%), phlebitis (0.9%), DVT (1.0%), catheter malposition (1.1%), catheter breakage (0.1%), and liquid extravasation (1.8%). In multivariable logistic regression analyses, hyperlipidemia, diabetes mellitus, lung cancer, stomach cancer, and lymphoma were significantly associated with increased risk of complications, as the independent risk factors. Conclusions: This retrospective clinical study demonstrates that ECG-guided insertion of a new tip-conductive PICC is associated with a high rate of first-attempt success and low rate of catheter related complications.

Abstract Background Mycobacterium septicum is a rapidly growing non-tuberculous mycobacterium. It is a ubiquitous organism capable of causing infections in both healthy and immunocompromised individuals. Only a few cases have been reported to date, and standard therapeutic regimens, and optimal treatment duration have not been defined. Methods We conducted a retrospective chart review of all patients seen at Mayo Clinic in Rochester, MN from July 2014 to March 2020 from whom Mycobacterium septicum was isolated in culture by our clinical microbiology laboratory. Results There were 12 patients identified with M. septicum infection – 7 males and 5 females. The average age was 67 years, with an age range of 48 to 80 years. Seven of 12 isolates obtained were from sputum samples. Only one patient was on immunosuppressive medication. Three cases were considered clinically significant infections for which directed anti-mycobacterial therapy was instituted. In two of these three cases, co-infection with Mycobacterium avium complex (MAC) was seen. Underlying structural lung disease was present in the two cases of pulmonary infections. Peritoneal dialysis catheter-related peritonitis was seen in the third case. All the isolates were susceptible to amikacin, ciprofloxacin, imipenem, linezolid, moxifloxacin, and trimethoprim-sulfamethoxazole (TMP-SMX). The isolates were resistant to clarithromycin and doxycycline. Patient Characteristics, Associated M. septicum Illness, and Therapy Provided Antimicrobial Susceptibility Profiles of the Mycobacterium septicum Isolates, MIC (mcg/mL) and Interpretation Patient Demographics and Specimen Source of Mycobacerium septicum Isolates Conclusion M. septicum is an unusual cause of non-tuberculous mycobacterial infection. The presence of a foreign body may increase the risk of infection. Individuals with underlying structural lung disease are also likely to be at increased risk of developing pulmonary infection. Generalized treatment recommendations are limited by the lack of prospective controlled trials; hence, optimal antibiotic regimen and treatment duration have not been firmly established. Susceptibility testing should be performed to guide treatment selection, but the use of combination therapy with potentially empiric agents like amikacin, ciprofloxacin, imipenem, linezolid, moxifloxacin, and TMP-SMX as demonstrated in this small study, can be considered. A high rate of macrolide resistance was noted in our study. Disclosures All Authors: No reported disclosures

Clavicle Fractures

Abstract Introduction Due to an increased risk of complications, lateral clavicle fractures are usually managed operatively. Unfortunately, there is no consensus on the optimal method of fixation. Method We assessed practice in our regional trauma unit by retrospectively identifying patients who underwent fixation of a lateral clavicle fracture between 1st August 2014 and 31st July 2019. Data was extracted from electronic care records and imaging systems. Results 44 patients were included, with the following demographics: mean age 26 years, 63.6% male, 65.9% high energy injury, and 68.2% Neer II fracture. The following operations were performed; hook plate fixation (HPF) = 10, locking plate fixation (LPF) = 16, coracoclavicular ligament reconstruction (CCLR) = 12, and LPF + CCLR = 6. Patients having LPF had a significantly larger post-operative coracoclavicular distance (7.6mm vs 13.5mm, p < 0.01), and a trend towards incomplete acromioclavicular joint reduction (50.0% vs 89.3%, p = 0.11). There was a significantly higher re-operation rate after HPF (100% vs 23.5%, p < 0.01). Conclusions In our unit there is no favoured method of fixation of lateral clavicle fractures. When LPF is used, there should be consideration of concomitant CCLR. The high rate of re-operation after HPF must be considered.

Background: Circulating progenitor cells (CPCs) and endothelial progenitor cells (EPCs) are immature cells involved in vascular repair and related to many aspects of macro and microvascular disease. <p> Objective: We aimed to review studies reporting the prognostic role of CPCs/EPCs measurement on development of cardiovascular disease and microangiopathy. <p> Methods and Results: We reviewed the English language literature for prospective observational studies reporting the future development of cardiovascular disease or microangiopathy in patients having a baseline determination of CPCs/EPCs. We retrieved 34 studied reporting on cardiovascular outcomes and 2 studies reporting on microvascular outcomes. Overall, a reduced baseline level of CPCs/EPCs was associated with a significant increased risk of cardiovascular events, all-cause death, and onset/progression of microangiopathy. The most predictive phenotypes were CD34+ and CD34+CD133+. The main limitation was related to the high heterogeneity among studies in terms of patient characteristics and cell phenotypes. <p> Conclusion: The present review shows that a reduced level of circulating progenitor cells is a risk factor for the development of future cardiovascular events and death. In addition, low CPCs/EPCs levels predict the onset or worsening of microalbuminuria and retinopathy in diabetic patients.

Abstract Background The incidence, characteristics, determinants, and prognostic impact of recurrent syncope are largely unknown, causing uncertainty for both patients and physicians. Methods We characterized recurrent syncope including sex-specific aspects and its impact on death and major adverse cardiovascular events (MACE) in a large prospective international multicenter study enrolling patients ≥40 years presenting with syncope to the emergency department (ED). Syncope etiology was centrally adjudicated by two independent and blinded cardiologists using all information becoming available during syncope work-up and 12-month follow-up. MACE were defined as a composite of all-cause death, acute myocardial infarction, surgical or percutaneous coronary intervention, life-threatening arrhythmia including cardiac arrest, pacemaker or implantable cardioverter defibrillator implantation, valve intervention, heart-failure, gastrointestinal bleeding or other bleeding requiring transfusion, intracranial hemorrhage, ischemic stroke or transient ischemic attack, sepsis and pulmonary embolism. Results Incidence of recurrent syncope among 1790 patients was 20% (95%-confidence interval (CI) 18% to 22%) within 24 months. Patients with an adjudicated final diagnosis of cardiac syncope (hazard ratio (HR) 1.50, 95%-CI 1.11 to 2.01) or syncope of unknown etiology even after central adjudication (HR 2.11, 95%-CI 1.54 to 2.89) had an increased risk for syncope recurrence (Figure). LASSO regression fit on all patient information available early in the ED identified more than three previous episodes of syncope as the only independent predictor for recurrent syncope (HR 2.13, 95%-CI 1.64 to 2.75). Recurrent syncope within the first 12 months after the index event carried an increased risk for all-cause death (HR 1.59, 95%-CI 1.06 to 2.38) and MACE (HR 2.24, 95%-CI 1.67 to 3.01), whereas recurrences after 12 months did not have a significant impact on outcome measures. Conclusion Recurrence rates of syncope are substantial and vary depending on syncope etiology. There seem to be no reliable patient characteristics available early on the ED that allow for the prediction of recurrent syncope with only a history of more than three previous syncope being associated with a higher risk for future recurrences. Importantly, recurrent syncope within the first 12 months carries an increased risk for death and MACE.

Purpose: To understand the association between biomarkers and exacerbations of severe asthma in adult patients in Taiwan. Materials and Methods: Demographic, clinical characteristics and biomarkers were retrospectively collected from the medical charts of severe asthma patients in six hospitals in Taiwan. Exacerbations were defined as those requiring asthma-specific emergency department visits/hospitalizations, or systemic steroids. Enrolled patients were divided into: (1) those with no exacerbations (non-exacerbators) and (2) those with one or more exacerbations (exacerbators). Receiver operating characteristic curves were used to determine the optimal cut-off value for biomarkers. Generalized linear models evaluated the association between exacerbation and biomarkers. Results: 132 patients were enrolled in the study with 80 non-exacerbators and 52 exacerbators. There was no significant difference in demographic and clinical characteristics between the two groups. Exacerbators had significantly higher eosinophils (EOS) counts (367.8 ± 357.18 vs. 210.05 ± 175.24, p = 0.0043) compared to non-exacerbators. The optimal cut-off values were 292 for EOS counts and 19 for the Fractional exhaled Nitric Oxide (FeNO) measure. Patients with an EOS count ≥ 300 (RR = 1.88; 95% CI, 1.26–2.81; p = 0.002) or FeNO measure ≥ 20 (RR = 2.10; 95% CI, 1.05–4.18; p = 0.0356) had a significantly higher risk of exacerbation. Moreover, patients with both an EOS count ≥ 300 and FeNO measure ≥ 20 had a significantly higher risk of exacerbation than those with lower EOS count or lower FeNO measure (RR = 2.16; 95% CI, 1.47–3.18; p = < 0.0001). Conclusions: Higher EOS counts and FeNO measures were associated with increased risk of exacerbation. These biomarkers may help physicians identify patients at risk of exacerbations and personalize treatment for asthma patients.
