Catheter-related bloodstream infection (CRBSI) with hemodialysis catheters are associated with increased mortality, morbidity and pose significant financial burden on healthcare. Antibiotic and antimicrobial locking solutions are effective in reducing risk of CRBSI. From inception to April 2020, we looked for relevant clinical controlled trials throughout the following databases: EBSCO, PubMed, Cochrane CENTRAL, MEDLINE, EMBASE, clinicaltrial.gov, and Google Scholar performing a metanalysis comparing antibiotic and antimicrobial lock solutions to heparin. Twenty-six studies with 4,967 patients reported the incidence of catheter-related bacteremia (CRB). The overall pooled risk ratio (RR) showed that the intervention group was associated with a significantly lower incidence of CRB by 30% compared with heparin (RR = 0.30, 95% confidence interval [CI] [0.25, 0.36], p < 0.001). Subgroup analysis showed that administration of antibiotic regimens led to a decreased risk of CRB episodes by 28% compared with the heparin group (RR = 0.28, 95% CI [0.21, 0.37], p < 0.0001). Antimicrobial solutions was associated with reduced risk of CRB by 32% compared with patients of the control group (RR = 0.32, 95% CI [0.25, 0.41], p < 0.0001). A test of subgroup differences was revealed no significant favoring of any of the two interventions. Both antibiotic and antimicrobial solutions are effective in reducing CRBSI.

SUMMARY Background This study aimed to determine the incidence, as well as evaluate risk factors, and impact of gastrointestinal bleeding on outcomes and resource use in patients admitted for salicylate poisoning. Methods We used the National Inpatient Sample to construct a cohort of patients hospitalized primarily for salicylate poisoning from 2003 to 2014. We compared clinical characteristics, in-hospital treatments, outcomes and resource use between salicylate poisoning patients with and without gastrointestinal bleeding. Results Of 13 805 hospital admissions for salicylate poisoning, gastrointestinal bleeding occurred in 482 (3.5%) admissions. The risk factors for gastrointestinal bleeding included older age, history of atrial fibrillation and cirrhosis. After adjusting for difference in baseline characteristics, patients with gastrointestinal bleeding required more gastric lavage, gastrointestinal endoscopy, invasive mechanical ventilation and red blood cell transfusion. Gastrointestinal bleeding was significantly associated with increased risk of anemia, circulatory, liver and hematological failure but was not significantly associated with increased in-hospital mortality. The length of hospital stay and hospitalization cost was significantly higher in patients with gastrointestinal bleeding. Conclusion Gastrointestinal bleeding occurred in about 4% of patients admitted for salicylate poisoning. Gastrointestinal bleeding was associated with higher morbidity and resource use but not mortality.

Abstract Background: Cardiac dyssynchronization is the proposed mechanism for pacemaker-induced cardiomyopathy. The standard of treatment is biventricular pacing. Left bundle branch pacing and His bundle pacing are novel interventions that imitate the natural conductionof the heart with, theoretically, less interventricular dysynchrony. One of the surrogate markers of interventricular synchrony is QRS duration. Our study aimed to compare the change of QRS duration before and after implantation between types of cardiac implantable electronic device (CIED): left bundle branch pacing versus His bundle pacing versus biventricular pacing and conventional right ventricular pacing. Methods: A literature search for studies that reported an interval change of QRS duration after CIED implantation was conducted utilizing the MEDLINE, EMBASE, and Cochrane databases. All relevant work through September 2020 from these databases was included in this analysis. A random-effects model network meta-analysis was used to analyze QRS duration changes (i.e., electrical cardiac synchronization) across different CIED implantations. Results: The mean study sample size, from 16 included studies, was 185 subjects. According to SUCRA analysis for the studies analyzed, the His bundle pacing intervention resulted in the most dramatic decline in QRS duration (mean difference -53 ms, 95% CI -67, -39), followed by left bundle branch pacing (mean difference -46 ms, 95% CI -60, -33) and biventricular pacing (mean difference -19 ms, 95% CI -37, -1.8), when compared to conventional right ventricle apical lead placement. Conclusion: Our network meta-analysis found that His bundle branch pacing devices have the greatest effect on QRS duration reduction after implantation, followed by left bundle branch pacing. Physiologic pacing interventions result in improved electrocardiography markers of cardiac synchronicity, narrower QRS duration, and might lower electromechanical dyssynchrony.

Introduction As percutaneous coronary intervention (PCI) technologies have been far improved, we hence conducted an updated systemic review and meta-analysis to determine the comparability between coronary artery bypass graft (CABG) and PCI with drug-eluting stent (DES) in ESRD patients. Methods We comprehensively searched the databases of MEDLINE, EMBASE, PUBMED and the Cochrane from inception to January 2020. Included studies were published observational studies that compared the risk of cardiovascular outcomes among dialysis patients with CABG and DES. Data from each study were combined using the random-effects, generic inverse variance method of DerSimonian and Laird to calculate risk ratios and 95% confidence intervals. Subgroup analyses and meta-regression were performed to explore heterogeneity. Results Thirteen studies were included in this analysis, involving total 56 422 (CABG 21 740 and PCI 34 682). Compared with DES, our study demonstrated CABG had higher 30-day mortality [odds ratio (OR) 3.85, P = 0.009] but lower cardiac mortality (OR 0.78, P < 0.001), myocardial infarction (OR 0.5, P < 0.001) and repeat revascularization (OR 0.35, P < 0.001). No statistical differences were found between CABG and DES for long-term mortality (OR 0.92, P = 0.055), composite outcomes (OR 0.88, P = 0.112) and stroke (OR 1.49, P = 0.457). Meta-regression suggested diabetes and the presence of left main coronary artery disease as an effect modifier of long-term mortality. Conclusion PCI with DES shared similar long-term mortality, composite outcomes and stroke outcomes to CABG among dialysis patients but still was associated with an improved 30-day survival . However, CABG had better rates of myocardial infarction, repeat revascularization and cardiac mortality.

Background: This study aimed to evaluate the risk factors for circulatory shock and its impact on outcomes in patients hospitalized for salicylate intoxication. Methods: We used the National Inpatient Sample to identify patients hospitalized primarily for salicylate intoxication from 2003–2014. Circulatory shock was identified based on hospital diagnosis code for any type of shock or hypotension. We compared clinical characteristics, in-hospital treatments, outcomes, and resource use between patients with and without circulatory shock associated with salicylate intoxication. Results: Of 13,805 hospital admissions for salicylate intoxication, circulatory shock developed in 484 (4%) admissions. Risk factors for development of circulatory shock included older age, female sex, concurrent psychotropic medication overdose, anemia, congestive heart failure, volume depletion, rhabdomyolysis, seizure, gastrointestinal bleeding, and sepsis. Circulatory shock was significantly associated with increased odds of any organ failure and in-hospital mortality. Length of hospital stay and hospitalization cost was significantly higher in patients with circulatory shock. Conclusion: Approximately 4% of patients admitted for salicylate intoxication developed circulatory shock. Circulatory shock was associated with worse clinical outcomes and increased resource use.

Background There are limited contemporary data prevalence and outcomes of acute ischemic stroke (AIS) complicating acute myocardial infarction (AMI). Methods and Results Adult (>18 years) AMI admissions using the National Inpatient Sample database (2000–2017) were evaluated for in‐hospital AIS. Outcomes of interest included in‐hospital mortality, hospitalization costs, length of stay, discharge disposition, and use of tracheostomy and percutaneous endoscopic gastrostomy. The discharge destination was used to classify survivors into good and poor outcomes. Of a total 11 622 528 AMI admissions, 183 896 (1.6%) had concomitant AIS. As compared with 2000, in 2017, AIS rates increased slightly among ST‐segment–elevation AMI (adjusted odds ratio, 1.10 [95% CI, 1.04–1.15]) and decreased in non–ST‐segment–elevation AMI (adjusted odds ratio, 0.47 [95% CI, 0.46–0.49]) admissions ( P <0.001). Compared with those without, the AIS cohort was on average older, female, of non‐White race, with greater comorbidities, and higher rates of arrhythmias. The AMI‐AIS admissions received less frequent coronary angiography (46.9% versus 63.8%) and percutaneous coronary intervention (22.7% versus 41.8%) ( P <0.001). The AIS cohort had higher in‐hospital mortality (16.4% versus 6.0%; adjusted odds ratio, 1.75 [95% CI, 1.72–1.78]; P <0.001), longer hospital length of stay, higher hospitalization costs, greater use of tracheostomy and percutaneous endoscopic gastrostomy, and less frequent discharges to home (all P <0.001). Among AMI‐AIS survivors (N=153 318), 57.3% had a poor functional outcome at discharge with relatively stable temporal trends. Conclusions AIS is associated with significantly higher in‐hospital mortality and poor functional outcomes in AMI admissions.

Background: This study aimed to evaluate thrombotic microangiopathy’s (TMA) incidence, risk factors, and impact on outcomes and resource use in hospitalized patients with systemic lupus erythematosus (SLE). Methods: We used the National Inpatient Sample to construct a cohort of hospitalized patients with SLE from 2003–2014. We compared clinical characteristics, in-hospital treatments, outcomes, and resource use between SLE patients with and without TMA. Results: Of 35,745 hospital admissions for SLE, TMA concurrently presented or developed in 188 (0.5%) admissions. Multivariable analysis showed that age ≥ 40 years and Hispanics were significantly associated with decreased risk of TMA, whereas Asian/Pacific Islanders and history of chronic kidney disease were significantly associated with increased risk of TMA. TMA patients required more kidney biopsy, plasmapheresis, mechanical ventilation, and renal replacement therapy. TMA was significantly associated with increased risk of in-hospital mortality and acute conditions including hemoptysis, glomerulonephritis, encephalitis/myelitis/encephalopathy, hemolytic anemia, pneumonia, urinary tract infection, sepsis, ischemic stroke, seizure, and acute kidney injury. The length of hospital stays and hospitalization cost was also significantly higher in SLE with TMA patients. Conclusion: TMA infrequently occurred in less than 1% of patients admitted for SLE, but it was significantly associated with higher morbidity, mortality, and resource use.

Background: Fabry disease (FD) is a rare X-linked lysosomal storage disorder with progressive systemic deposition of globotriaosylceramide, leading to life-threatening cardiac, central nervous system, and kidney disease. Current therapy involves symptomatic medical management, enzyme replacement therapy (ERT), dialysis, kidney transplantation, and, more recently, gene therapy. The aim of this systematic review was to assess outcomes of kidney transplantation among patients with FD. Methods: A comprehensive literature review was conducted utilizing MEDLINE, EMBASE, and Cochrane Database, from inception through to 28 February 2020, to identify studies that evaluate outcomes of kidney transplantation including patient and allograft survival among kidney transplant patients with FD. Effect estimates from each study were extracted and combined using the random-effects generic inverse variance method of DerSimonian and Laird. Results: In total, 11 studies, including 424 kidney transplant recipients with FD, were enrolled. The post-transplant median follow-up time ranged from 3 to 11.5 years. Overall, the pooled estimated rates of all-cause graft failure, graft failure before death, and allograft rejection were 32.5% (95%CI: 23.9%–42.5%), 14.5% (95%CI: 8.4%–23.7%), and 20.2% (95%CI: 15.4%–25.9%), respectively. In the sensitivity analysis, limited only to the recent studies (year 2001 or newer when ERT became available), the pooled estimated rates of all-cause graft failure, graft failure before death, and allograft rejection were 28.1% (95%CI: 20.5%–37.3%), 11.7% (95%CI: 8.4%–16.0%), and 20.2% (95%CI: 15.5%–26.0%), respectively. The pooled estimated rate of biopsy proven FD recurrence was 11.1% (95%CI: 3.6%–29.4%), respectively. There are no significant differences in the risks of all-cause graft failure (p = 0.10) or mortality (0.48) among recipients with vs. without FD. Conclusions: Despite possible FD recurrence after transplantation of 11.1%, allograft and patient survival are comparable among kidney transplant recipients with vs. without FD.

Background: The objective of this study was to report the incidence of in-hospital serum ionized calcium derangement and its impact on mortality. Methods: We included 12,599 non-dialytic adult patients hospitalized at a tertiary medical center from January 2009 to December 2013 with normal serum ionized calcium at admission and at least 2 in-hospital serum ionized calcium values. Using serum ionized calcium of 4.60–5.40 mg/dL as the normal reference range, in-hospital serum ionized calcium levels were categorized based on the presence of hypocalcemia and hypercalcemia in hospital. We performed logistic regression to assess the relationship of in-hospital serum ionized calcium derangement with mortality. Results: Fifty-four percent of patients developed new serum ionized calcium derangements: 42% had in-hospital hypocalcemia only, 4% had in-hospital hypercalcemia only, and 8% had both in-hospital hypocalcemia and hypercalcemia. In-hospital hypocalcemia only (OR 1.28; 95% CI 1.01–1.64), in-hospital hypercalcemia only (OR 1.64; 95% CI 1.02–2.68), and both in-hospital hypocalcemia and hypercalcemia (OR 1.73; 95% CI 1.14–2.62) were all significantly associated with increased in-hospital mortality, compared with persistently normal serum ionized calcium levels. Conclusions: In-hospital serum ionized calcium derangements affect more than half of hospitalized patients and are associated with increased in-hospital mortality.
