Abstract Background: Many studies have shown that vancomycin is inferior to β-lactam antibiotics in terms of effectiveness in the treatment of methicillin-susceptible Staphylococcus aureus (MSSA) bacteremia. However, limited data are available regarding the comparison of clinical outcomes between patients receiving initial teicoplanin and those receiving β-lactam antibiotics for MSSA bacteremia.Methods: Eighty-four adults with MSSA bacteremia were included: initial teicoplanin treatment group (n=28) and β-lactam treatment group (n=56). The two groups were further stratified based on propensity score matching according to the outcome analysis using a logistic regression model. We investigated the clinical outcomes between the groups before and after propensity score matching after treatment completion.Results: Pittsburgh bacteremia score ≥4 (odds ratio, 60.6; 95%CI, 7.4–496.8) was an independent risk factor for unfavorable outcome. After propensity score matching, the initial teicoplanin treatment group and the β-lactam treatment group consisted of 28 patients each. No statistically significant differences were observed in the proportions of patients with favorable outcomes and 30-day overall mortality rates between the groups before and after propensity score matching after the completion of teicoplanin or β-lactam treatment. The Kaplan-Meier 30-day survival curve also showed no significant difference between the patients receiving initial teicoplanin treatment and those receiving β-lactam treatment before and after matching (hazard ratio, 1.84, 95%CI, 0.60–5.64; and 3.12, 95%CI, 0.98–9.99, respectively).Conclusions: There were no significant difference in clinical outcomes between initial teicoplanin treatment and β-lactam treatment among patients with MSSA bacteremia. Pittsburgh bacteremia score ≥4 was a significant risk factor for mortality.

Introduction: There are no randomized controlled trials that compared the outcomes of leadless pacemaker (L-PPM) implantation with transvenous pacemaker (TV-PPM) and there is scarcity of data on real world outcomes. Methods: We queried National Inpatient Sample to identify all adult patients who had primary discharge diagnosis of conduction disorders or tachy-arrhythmias and excluded patients who had a concomitant procedure for valve replacement, coronary artery bypass grafting, ablation and/or cardiac implantable electronic device removal so that complications can be attributed to the pacemaker implantation. We included only procedures from November 2016 to December 2017 as Micra was the only available L-PPM during that period. For the comparison cohort we selected patients, during the same time period, who had a procedure code for single chamber pacemaker implantation in conjunction with right ventricular lead placement. We performed 1:1 propensity score matching and the variables used for matching are marked with asterisk in Table 1. All the codes used to identify complications has been previously validated from the Micra Post-approval registry and Coverage with Evidence Study. Results: Total of 1,305 patients for L-PPM and 13,905 patients in the TV-PPM group were included. Baseline characteristics with standardized mean difference before and after matching are shown in Table 1. Briefly, patients in L-PPM group were younger but had higher co-morbidities compared to TV-PPM group. The complications before and after matching are shown in Table 2. Conclusions: In conclusion, we found no significant difference between in-hospital complications after propensity score matching, with the exception of deep venous thrombosis. There was no difference between length of stay but cost for L-PPM was significantly higher. In this real-world analysis, we found that the leadless PPM implantation is safe in comparison to transvenous PPM.

Abstract Background Oral switch to linezolid is a promising alternative to standard parenteral therapy (SPT) in Staphylococcus aureus bacteremia (SAB). Methods We conducted a prospective cohort study of all adult cases of SAB between 2013 and 2017 in a Spanish university hospital. We compared the efficacy, safety, and length of hospital stay of patients receiving SPT and those where SPT was switched to oral linezolid between days 3 and 9 of treatment until completion. We excluded complicated SAB and osteoarticular infections. A k-nearest neighbor algorithm was used for propensity score matching with a 2:1 ratio. Results After propensity score matching, we included 45 patients from the linezolid group and 90 patients from the SPT group. Leading SAB sources were catheter related (49.6%), unknown origin (20.0%), and skin and soft tissue (17.0%). We observed no difference in 90-day relapse between the linezolid group and the SPT group (2.2% vs 4.4% respectively; P = .87). No statistically significant difference was observed in 30-day all-cause mortality between the linezolid group and the SPT group (2.2% vs 13.3%; P = .08). The median length of hospital stay after onset was 8 days in the linezolid group and 19 days in the SPT group (P < .01). No drug-related events leading to discontinuation were noted in the linezolid group. Conclusions Treatment of SAB in selected low-risk patients with an oral switch to linezolid between days 3 and 9 of treatment until completion yielded similar clinical outcomes as SPT, allowing earlier discharge from the hospital.

Abstract Background Percutaneous coronary intervention (PCI) for coronary chronic total occlusions (CTOs) remains among the biggest challenges in interventional cardiology. However, limited data exist regarding the clinical outcomes of the three potential therapeutic strategies of PCI, coronary artery bypass grafting (CABG), and medical therapy (MT). Aims The aim of this study was to compare the clinical outcomes of CTO patients according to the initial treatment strategy. Methods and results Consecutive patients with at least one coronary CTO from January 2007 to December 2016 in our center were included and categorized as managed either by PCI, CABG, or MT. Propensity-score matching was also performed to adjust for baseline characteristics. The primary outcome was a major adverse cardiac event (MACE), such as cardiac death, myocardial infarction (MI), or target vessel revascularization (TVR). A total of 1655 patients with 1944 CTOs were enrolled in this study. The overall CTO prevalence was 10.5%. A CTO was treated by MT in 800 (48.3%) patients and PCI in 734 (44.4%), while 121 (7.3%) underwent CABG. The median overall follow-up duration was 3.6 (interquartile range = 2.1 to 5.0) years. Patients referred for MT had a higher incidence of MACE (28.0% vs. 17.3% and 12.4%, respectively; all p<0.001) and TVR (16.9% vs. 10.6% and vs. 7.4%, respectively; p<0.001 and = 0.005, respectively) than those managed by PCI and CABG. After propensity-score matching analysis, the rate of PCI was lower than that of MACE (19.2% vs. 28.9%, hazard ratio [HR] = 0.62, 95% confidence interval [CI] = 0.45–0.85, p=0.003) and TVR (HR = 0.53, 95% CI = 0.35–0.79, p=0.002) when compared with MT. There was no significant difference in the prevalence of MACE (18.5% vs. 23.1%, HR = 0.76, 95% CI = 0.53–1.09, p=0.126) or cardiac death (0.51; 0.23–1.15, 0.098) between the successful PCI and MT groups. Conclusions As an initial management strategy for patients with CTOs, PCI or CABG reduced the risk of MACE (driven by TVR), as compared with MT alone on follow-up. However, successful PCI did not reduce the long-term risk of MACE or cardiac death, as compared with MT alone.

Abstract Background To explore the correlation between the preoperative systemic immune inflammation index (SII) and the prognosis of patients with gastric carcinoma (GC). Methods The clinical data of 771 GC patients surgically treated in the Department of Gastrointestinal Surgery, Qinghai University Affiliated Hospital from June 2010 to June 2015 were retrospectively analyzed, and their preoperative SII was calculated. The optimal cut-off value of preoperative SII was determined using the receiver operating characteristic (ROC) curve, the confounding factors between the two groups were eliminated using the propensity score matching (PSM) method, and the correlation between preoperative SII and clinicopathological characteristics was assessed by chi-square test. Moreover, the overall survival was calculated using Kaplan-Meier method, the survival curve was plotted, and log-rank test was performed for the significance analysis between the curves. Univariate and multivariate analyses were also conducted using the Cox proportional hazards model. Results It was determined by the ROC curve that the optimal cut-off value of preoperative SII was 489.52, based on which 771 GC patients were divided into high SII (H-SII) group and low SII (L-SII) group, followed by PSM in the two groups. The results of Kaplan-Meier analysis showed that before and after PSM, the postoperative 1-, 3-, and 5-year survival rates in L-SII group were superior to those in H-SII group, and the overall survival rate had a statistically significant difference between the two groups (P < 0.05). Before PSM, preoperative SII [hazard ratio (HR) = 2.707, 95% confidence interval (CI) 2.074-3.533, P < 0.001] was an independent risk factor for the prognosis of GC patients. After 1:1 PSM, preoperative SII (HR = 2.669, 95%CI 1.881–3.788, P < 0.001) was still an independent risk factor for the prognosis of GC patients. Conclusions Preoperative SII is an independent risk factor for the prognosis of GC patients. The increase in preoperative SII in peripheral blood indicates a worse prognosis.

OBJECTIVEHealthcare costs continue to escalate. Approaches to care that have comparable outcomes and complications are increasingly assessed for quality improvement and, when possible, cost containment. Efforts to identify components of care to reduce length of stay (LOS) have been ongoing. Spinal anesthesia (SA), for select lumbar spine procedures, has garnered interest as an alternative to general anesthesia (GA) that might reduce cost and in-hospital LOS and accelerate recovery. While clinical outcomes with SA or GA have been studied extensively, few authors have looked at the cost-analysis in relation to clinical outcomes. The authors’ objectives were to compare the clinical perioperative outcomes of patients who received SA and GA, as well as the direct costs associated with each modality of care, and to determine which, in a retrospective analysis, can serve as a dominant procedural approach.METHODSThe authors retrospectively analyzed a homogeneous surgical population of 550 patients who underwent hemilaminotomy for disc herniation and who received either SA (n = 91) or GA (n = 459). All clinical and billing data were obtained via each patient’s chart and the hospital’s billing database, respectively. Additionally, the authors prospectively assessed patient-reported outcome measures for a subgroup of consecutively treated patients (n = 75) and compared quality-adjusted life year (QALY) gains between the two cohorts. Furthermore, the authors performed a propensity score–matching analysis to compare the two cohorts (n = 180).RESULTSDirect hospital costs for patients receiving SA were 40% higher, in the hundreds of dollars, than for patients who received GA (p < 0.0001). Furthermore, there was a significant difference with regard to LOS (p < 0.0001), where patients receiving SA had a considerably longer hospital LOS (27.6% increase in hours). Patients undergoing SA had more comorbidities (p = 0.0053), specifically diabetes and hypertension. However, metrics of complications, including readmission (p = 0.3038) and emergency department (ED) visits at 30 days (p = 1.0), were no different. Furthermore, in a small pilot group, QALY gains were statistically no different (n = 75, p = 0.6708). Propensity score–matching analysis demonstrated similar results as the univariate analysis: there was no difference between the cohorts regarding 30-day readmission (p = 1.0000); ED within 30 days could not be analyzed as there were no patients in the SA group; and total direct costs and LOS were significantly different between the two cohorts (p < 0.0001 and p = 0.0126, respectively).CONCLUSIONSBoth SA and GA exhibit the qualities of a good anesthetic, and the utilization of these modalities for lumbar spine surgery is safe and effective. However, this work suggests that SA is associated with increased LOS and higher direct costs, although these differences may not be clinically or fiscally meaningful.

Objective To investigate if the use of therapeutic agents for dysuria is a risk factor for the primary recurrence of non-muscle invasive bladder cancer (NMIBC). Methods First, patients with NMIBC were divided into two groups: the non-recurrence group and the recurrence group. Patient characteristics were compared between both groups. The risk factors of recurrence that were statistically different between the two groups were identified by multivariate analysis. Second, we divided the patients into risk and non-risk groups, and differences in the recurrence-free survival (RFS) between the two groups were analyzed before and after propensity score matching (PSM). Results A total of 162 patients were included, with 84 patients in the non-recurrence group and 78 patients in the recurrence group. In the multivariate analysis, the intake of dysuria agents and bacillus Calmette–Guérin (BCG) therapy were independent factors. The RFS results in terms of the intake of dysuria agents were statistically significant before and after PSM analysis, but no factors were significantly different between the BCG and non-BCG groups after PSM. Conclusions Therapeutic agents for dysuria might be at an independent risk factor for NMIBC recurrence. This trial is registered with the UMIN Clinical Trials Registry under the number UMIN000036097 ( https://upload.umin.ac.jp/cgi-open-bin/ctr/ctr_view.cgi?recptno = R000041122 ).

Objectives This study aimed to compare the mid-term clinical outcomes of intravascular ultrasound (IVUS)-calcified nodules between percutaneous coronary intervention (PCI) with and without rotational atherectomy (RA). Background There has been a debate whether to use RA for the revascularization of calcified nodule. Although RA can ablate the calcified structure within calcified nodule and may facilitate adequate stent expansion, RA may provoke severe coronary perforation, because calcified nodule typically shows eccentric calcification. Methods We included 204 lesions with IVUS-calcified nodule, and divided into 73 lesions treated with RA (RA group) and 131 lesions without RA (non-RA group). After propensity-score matching, 42 lesions with RA (matched RA group) and 42 lesions without RA (matched non-RA group) were selected. We compared the clinical characteristics and outcomes between the 2 groups before and after propensity-score matching. The primary endpoint was ischemia-driven target vessel revascularization (TVR) within 1 year. Results Acute lumen area gain on IVUS was comparable between the matched RA group and matched non-RA group (3.9 ± 2.1 mm2 vs. 3.4 ± 1.6 mm2, p = 0.18). The stent malapposition at calcified nodules was frequently observed in both groups. The ischemia-driven TVR was not different between the 2 groups before (p = 0.82) and after propensity score-matching (p = 0.87). Conclusions The use of RA could not reduce the incidence of ischemia-driven TVR in lesions with IVUS-calcified nodule. Our results do not support the routine use of RA for lesions with IVUS-calcified nodule.

Abstract Background Mortality rates from Staphylococcus aureus bacteremia are high and have only modestly improved in recent decades. We compared the efficacies of a β-lactam in combination with daptomycin (BL/D-C) and β-lactam monotherapy (BL-M) in improving clinical outcomes in methicillin-susceptible S. aureus (MSSA) bacteremia. Methods A retrospective cohort study of MSSA bacteremia was performed in a tertiary hospital from January 2011 to December 2017. Patients receiving BL/D-C and BL-M were compared to assess 7-, 30-, and 90-day mortality rates. A 1:2 propensity score matching analysis was performed. Differences were assessed using Cox regression models. Results Of the 514 patients with MSSA bacteremia, 164 were excluded as they had received combination therapies other than BL/D-C, had pneumonia, or died within 48 hours of admission. Of the remaining 350 patients, 136 and 214 received BL/D-C and BL-M, respectively. BL/D-C patients had higher Pitt scores and persistent bacteremia more often than BL-M patients. In the raw analysis, there were no differences in mortality rates between groups. After propensity score matching, there were no significant differences between the BL/D-C (110 patients) and BL-M (168 patients) groups for all-cause mortality rates at 7 days (8.18% vs 7.74%; P = 1.000), 30 days (17.3% vs 16.1%; P = .922), and 90 days (22.7% vs 23.2%; P = 1.000), even in a subanalysis of patients with high-risk source of infection and in a subgroup excluding catheter-related bacteremia. Conclusions BL/D-C failed to reduce mortality rates in patients with MSSA bacteremia. Treatment strategies to improve survival in MSSA bacteremia are urgently needed.
