This study aimed to evaluate the accuracy of the HOSPITAL Score (Haemoglobin level at discharge, Oncology at discharge, Sodium level at discharge, Procedure during hospitalization, Index admission, number of hospital admissions, Length of stay) LACE index (Length of stay, Acute/emergent admission, Charlson comorbidy index score, Emerency department visits in previous 6 months) and LACE+ index in predicting 30-day readmission in patients with diastolic dysfunction. Heart failure remains one of the most common hospital readmissions in adults, leading to significant morbidity and mortality. Different models have been used to predict 30-day hospital readmissions. All adult medical patients discharged from the SIU School of Medicine Hospitalist service from 12 June 2016 to 12 June 2018 with an International Classification of Disease, 10th Revision, Clinical Modification diagnosis of diastolic heart failure were studied retrospectively to evaluate the performance of the HOSPITAL Score, LACE index and LACE+ index readmission risk prediction tools in this patient population. Of the 730 patient discharges with a diagnosis of heart failure with preserved ejection fraction (HFpEF), 692 discharges met the inclusion criteria. Of these discharges, 189 (27%) were readmitted to the same hospital within 30 days. A receiver operating characteristic evaluation showed C-statistic values to be 0.595 (95% CI 0.549 to 0.641) for the HOSPITAL Score, 0.551 (95% CI 0.503 to 0.598) for the LACE index and 0.568 (95% CI 0.522 to 0.615) for the LACE+ index, indicating poor specificity in predicting 30-day readmission. The result of this study demonstrates that the HOSPITAL Score, LACE index and LACE+ index are not effective predictors of 30-day readmission for patients with HFpEF. Further analysis and development of new prediction models are needed to better estimate the 30-day readmission rates in this patient population.
Purple urine bag syndrome (PUBS) is a rare condition in which there is purple discoloration of the urine with its collecting bag and associated tubing occurs. It is considered a benign condition. We report an unusual case of PUBS in an 87-year-old female from nursing home who had a history of recurrent UTI. She also had a history of ureteral obstruction requiring left nephrostomy tube. She was brought to emergency department with altered mental status which developed five days after the occurrence of purple discoloration of the urinary bag. Her urine culture grew vancomycin-resistant Enterococci (VRE) and Pseudomonas aeruginosa. She died within three days of hospitalization despite intensive care in tertiary center. This case highlights that PUBS may not always be benign and should be approached on a case-by-case basis because it may signal the underlying UTI which might be very difficult to treat. Failure of recognition of this peculiar color early could delay the appropriate intervention leading to fatal complication. This case also represents the rare occurrence of PUBS in the setting of nephrostomy tube.
Nivolumab is a checkpoint inhibiting immunotherapeutic agent prescribed for the treatment of resistant cancers. Many immune-related adverse effects including neurological effects have been described, but central nervous system (CNS) toxicities are rarely reported. We present a 59-year-old Caucasian woman with a history of treatment-resistant, progressive, laryngeal squamous cell carcinoma. She received nivolumab and presented with gradual weakness, confusion, and progressive dyspnea. Magnetic resonance imaging of the head showed multifocal cerebral demyelination, primarily involving the parietal lobe. The diagnosis of acute demyelinating encephalitis was made. She improved dramatically after stopping nivolumab and receiving treatment with high-dose intravenous steroid and immunoglobin therapy. We conclude, from this case and literature review, that immune checkpoint inhibitor treatment requires more investigation to determine if autoimmune encephalitis with demyelination can occur as a severe form of immune-related adverse events. CNS toxicity appears to be reversible with prompt cessation of immunotherapy followed by treatment with high doses of steroid with or without intravenous immunoglobulin therapy.
IMPORTANCEThe cardiovascular outcome in selected populations when sodium-glucose cotransporter 2 inhibitors (SGLT2-Is) are emerging as standard therapy is not clearly understood. It is important to learn the magnitude of cardiovascular benefit using SGLT2-Is across the select subgroups that include both sexes and multiple age and racial and ethnic groups. OBJECTIVESTo evaluate the association between use of SGLT2-Is and cardiovascular benefits in a prespecified group in a larger sample size using data obtained from randomized clinical trials. DATA SOURCESSearch of electronic databases PubMed, Google Scholar, Web of Science, and Cochrane from inception to January 10, 2021, with additional studies identified through conference papers and meeting presentations, ClinicalTrials.gov, and reference lists of published studies. STUDY SELECTION Placebo-controlled randomized clinical trials in which participants had atherosclerotic cardiovascular disease (ASCVD) or risk factors for ASCVD, diabetes, or heart failure and which reported the primary outcome were included in this study. Multicenter observational and nonobservational studies and those with different outcomes of interest were excluded. DATA EXTRACTION AND SYNTHESIS Medical Subject Heading search terms included SGLT2-I and multiple cardiovascular outcomes in different combinations. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. The analysis of all outcomes was performed using a Mantel-Haenszel equation and the randomeffects model. MAIN OUTCOMES AND MEASURES Six efficacy outcomes of SGLT2-I use (cardiovascular deathand hospitalization for heart failure [HHF] as the primary outcome and major adverse cardiovascular event, HHF, cardiovascular death, acute myocardial infarction, and all-cause mortality as secondary outcomes), were evaluated. Subgroup analysis was performed for the primary outcome of cardiovascular death or HHF. Odds ratios (ORs) and 95% CIs were used to compare 2 interventions. RESULTSTen studies with 71 553 participants were included, among whom 39 053 received SGLT2-Is; among studies that reported these data, 28 809 were men and 15 655 were women (mean age, 65.2 [range, 61.9-70.0] years). Race and ethnicity were defined in the original trials and were categorized as Asian, Black, or other (6900 participants) and White (26 646 participants) for the purposes of this analysis (the category "other" was not specified consistently). In terms of age, 16 793 were younger than 65 years and 17 087 were 65 years or older. At a mean follow-up 2.3 (range, (continued) Key Points Question What is the updated magnitude of benefit associated with sodium-glucose cotransporter 2 inhibitors (SGLT2-Is) on outcome of cardiovascular death or hospitalization for heart failure (HHF) in different select subgroups of patients? Findings This meta-analysis of 10 highquality randomized clinical trials (71 553 participants) found that use of SGLT2-Is was associated with lower occurrence of cardiovascular death...
Background: Pulmonary vein isolation (PVI) is the cornerstone of atrial fibrillation (AF) ablation but the recurrence rate remains relatively high in persistent patients with AF. Therefore, posterior wall isolation (PWI) in addition to PVI has been proposed to increase freedom from AF.Objective: To evaluate the success of adjunctive PWI in persistent AF. Methods:We searched electronic database using specific terms. The primary outcomes are recurrence rate of AF and recurrence of atrial arrhythmias. The secondary outcomes were atrial flutter/tachycardia (AFL/AT), procedure time, fluoroscopy time, and procedure related complications. Estimated risk ratios (RRs) and 95% confidence intervals (CIs) were evaluated.Results: Six studies were included (1334 patients with persistent AF). Adjunctive PWI resulted in a significant reduction in the recurrence rate of AF compared with patients who had PVI only (19.8% vs 29.1%; RR, 0.64; 95% CI, 0.42-0.97; P < .04; I 2 = 76%). There was a significant reduction in the recurrence rate of all atrial arrhythmia (30.8% vs 41.1%; RR, 0.75; 95% CI, 0.60-0.94; P < .01; I 2 = 60%). Compared with PVI only, adjunctive PWI did not increase the rate of AFL or AT (11.6% vs 13.9%; RR, 0.85; 95% CI, 0.54-1.32; P < .46; I 2 = 47%) or the rate of procedure related complications (4.6% vs 3.6%; RR, 1.25; 95% CI, 0.72-2.17; P < .44; I 2 = 0%). Conclusion:In patients with persistent AF, adjunctive PWI was associated with decreased recurrence of AF and atrial arrhythmias compared with PVI alone without an increased risk of AFL or AT or procedure related complications. K E Y W O R D Satrial fibrillation, atrial flutter, meta-analysis, posterior wall isolation, pulmonary vein isolation 1 | BACKGROUND Atrial fibrillation (AF) is the most common arrhythmia, with a prevalence of 0.5% to 1% of the population, 1 and is expected to rise even more over the next decades. 2 Historically management of AF has been geared toward rate control, or rhythm control with antiarrhythmic drugs. Over the last two decades, catheter ablation has emerged as an alternative for rhythm control with medications and is now a recognized first line therapy for the treatment of AF in select populations. This is emphasized for instance in the recent American College of Cardiology updated guidelines, which states that catheter ablation may be used in selected patients with symptomatic AF and heart failure with low ejection fraction based on data to support reduced hospitalization and potentially even reduce mortality. 3
