Heart failure with reduced ejection fraction (HFrEF) is associated with an increased risk of thrombotic events. We compared the safety and efficacy of different antithrombotic strategies for HFrEF and sinus rhythm. PubMed and Embase were searched through January 2020 for studies comparing oral anticoagulants versus antiplatelet agents or placebo in HFrEF and sinus rhythm to include in this network meta-analysis. We identified 5 randomized controlled trials with a total of 9,390 patients randomized to low dose rivaroxaban, vitamin K antagonist (VKA), antiplatelets, or placebo. Low dose rivaroxaban and VKA did not show a significant decrease in stroke compared with placebo but were associated with an increased risk of major bleeding (risk ratio [RR] 6.86, 95% confidence interval [CI] 1.16 to 40.7; RR 8.62, 95% CI 1.52 to 48.9, respectively). When compared with antiplatelets, low dose rivaroxaban and VKA were associated with a significantly decreased risk of stroke (RR 0.67, 95% CI 0.47 to 0.96; RR 0.50, 95% CI 0.33 to 0.76, respectively), but with a significantly increased risk of major bleeding (RR 1.65, 95% CI 1.16 to 2.33; RR 2.07, 95% CI 1.51 to 2.84, respectively). There was no significant difference in these outcomes between low dose rivaroxaban versus VKA and antiplatelets versus placebo. There were no significant differences in all-cause mortality, myocardial infarction, or rehospitalization for heart failure among each treatment. In conclusion, in patient with HFrEF and sinus rhythm, use of oral anticoagulation with or without antiplatelet agents increases the risk of bleeding without substantial effects on the risk of ischemic stroke.

Hepatotoxicity is a major immune-related adverse event that may become life-threatening. The impact of adding immune checkpoint blockade (ICB) to systemic therapy on the incidence of hepatotoxicity remains unknown. We performed a systematic review and meta-analysis to compare the incidence of hepatotoxicity among patients with cancer who received therapy with and without addition of ICB. PubMed, Embase, Web of Science, and Cochrane Library were searched to select phase 3 randomized controlled trials (RCTs) evaluating the effect of adding ICB to systemic therapy, placebo, or supportive care. The odds ratio (OR) of any grade and grade 3-5 hepatitis, elevations in aspartate aminotransferase (AST), and alanine aminotransferase (ALT) was pooled for meta-analysis. 43 RCTs with 28,905 participants were analyzed. Addition of ICB increased the incidence of hepatitis (any grade: OR, 2.13, 95% confidence interval [CI] 1.52-2.97, grade 3-5: OR, 2.66, 95% CI 1.72-4.11), elevated AST (any grade: OR, 2.16, 95% CI 1.73-2.70, grade 3-5: OR, 2.72, 95% CI 1.86-3.99), and elevated ALT (any grade: OR, 2.01, 95% CI 1.59-2.54, grade 3-5: OR, 2.40, 95% CI 1.62-3.55). Subgroup analysis based on the ICB mechanism revealed no significant heterogeneity among each mechanism for hepatitis (any Grade: I

OBJECTIVES Hemoptysis is a complication in cystic fibrosis (CF) patients, and is associated with pulmonary exacerbations and hospitalizations. Pancreatic insufficiency is common in CF patients, and therefore these patients may benefit from the use of vitamin K therapy. METHODS This was an observational study conducted in adult CF patients aiming to describe the utilization of vitamin K therapy in the setting of hemoptysis during an acute CF pulmonary exacerbation. An evaluation of hospital length of stay, time until the next pulmonary exacerbation, and 30-day re-admission rates were evaluated in CF patients who presented with hemoptysis and received vitamin K therapy. RESULTS The average dose of vitamin K therapy was 10 mg for an average duration of 4.9 ± 0.55 days for 38 adult CF patients included in this cohort. The median length of stay among patients who received vitamin K therapy was 8 days (IQR: 6-12 days). The median time until next hospital admission was 127 days (95% CI: 71.4 to 182.6 days), and the 30-day readmission rates were 7.89%. Two patients developed a thromboembolism after receiving vitamin K therapy. CONCLUSIONS Evidence for the use of vitamin K therapy in the setting of CF-related hemoptysis remains unclear, and warrants further safety and efficacy evaluation. Further prospective studies are needed to determine the appropriateness of dosing and duration of vitamin K therapy, as well as determining its role in the setting of the varying levels of hemoptysis during a pulmonary CF exacerbation.

The aim of this study was to assess the impact of aortic valve replacement (AVR) on survival in patients with each subclass of low-gradient (LG) aortic stenosis (AS) and to compare outcomes following surgical AVR (SAVR) and transcatheter AVR (TAVR).LG severe AS encompasses a wide variety of pathophysiology, including classical low-flow, LG (LF-LG), paradoxical LF-LG, and normal-flow, LG (NF-LG) AS, and uncertainty exists regarding the impact of AVR on each subclass of LG AS.PubMed and Embase were queried through October 2020 to identify studies comparing survival with different management strategies (SAVR, TAVR, and conservative) in patients with LG AS. Pairwise meta-analysis comparing AVR versus conservative management and network meta-analysis comparing SAVR versus TAVR versus conservative management were performed.Thirty-two studies with a total of 6,515 patients and a median follow-up time of 24.2 months (interquartile range: 36.5 months) were included. AVR was associated with a significant decrease in all-cause mortality in classical LF-LG (hazard ratio [HR]: 0.42; 95% confidence interval [CI]: 0.36 to 0.48), paradoxical LF-LG (HR: 0.41; 95% CI: 0.29 to 0.57), and NF-LG (HR: 0.41; 95% CI: 0.27 to 0.62) AS compared with conservative management. SAVR and TAVR were each associated with a decrease in all-cause mortality in classical LF-LG (HR: 0.46 [95% CI: 0.38 to 0.55] and 0.49 [95% CI: 0.37 to 0.64], respectively), paradoxical LF-LG (HR: 0.42 [95% CI: 0.28 to 0.65] and 0.42 [95% CI: 0.25 to 0.72], respectively), and NF-LG (HR: 0.40 [95% CI: 0.21 to 0.77] and 0.46 [95% CI: 0.26 to 0.84], respectively) AS compared with conservative management. No significant difference was observed between SAVR and TAVR.In all subclasses of LG AS, AVR was associated with a significant decrease in all-cause mortality regardless of surgical or transcatheter approach.

New York City emerged as an epicenter of the coronavirus disease 2019 (COVID-19) pandemic. To describe the clinical characteristics and risk factors associated with mortality in a large patient population in the USA. Retrospective cohort study. 6493 patients who had laboratory-confirmed COVID-19 with clinical outcomes between March 13 and April 17, 2020, who were seen in one of the 8 hospitals and/or over 400 ambulatory practices in the New York City metropolitan area Clinical characteristics and risk factors associated with in-hospital mortality. A total of 858 of 6493 (13.2%) patients in our total cohort died: 52/2785 (1.9%) ambulatory patients and 806/3708 (21.7%) hospitalized patients. Cox proportional hazard regression modeling showed an increased risk of in-hospital mortality associated with age older than 50 years (hazard ratio [HR] 2.34, CI 1.47–3.71), systolic blood pressure less than 90 mmHg (HR 1.38, CI 1.06–1.80), a respiratory rate greater than 24 per min (HR 1.43, CI 1.13–1.83), peripheral oxygen saturation less than 92% (HR 2.12, CI 1.56–2.88), estimated glomerular filtration rate less than 60 mL/min/1.73m2 (HR 1.80, CI 1.60–2.02), IL-6 greater than 100 pg/mL (HR 1.50, CI 1.12–2.03), D-dimer greater than 2 mcg/mL (HR 1.19, CI 1.02–1.39), and troponin greater than 0.03 ng/mL (HR 1.40, CI 1.23–1.62). Decreased risk of in-hospital mortality was associated with female sex (HR 0.84, CI 0.77–0.90), African American race (HR 0.78 CI 0.65–0.95), and hydroxychloroquine use (HR 0.53, CI 0.41–0.67). Among patients with COVID-19, older age, male sex, hypotension, tachypnea, hypoxia, impaired renal function, elevated D-dimer, and elevated troponin were associated with increased in-hospital mortality and hydroxychloroquine use was associated with decreased in-hospital mortality.

We present a case of reverse takotsubo syndrome (rTS) in a 68-year-old woman who presented with acute chest pain and flu-like symptoms. She was found to have elevated troponin and abnormal ECG. Urgent coronary angiogram revealed non-obstructive mild coronary artery disease of the left anterior descending artery. Left ventriculography demonstrated hypokinesis of the left ventricular base with sparing of the mid-ventricle and apex. Nasal viral PCR was positive for Influenza A. The diagnosis was confirmed with repeat echocardiogram 2 weeks later revealing resolution of regional wall motion abnormalities. rTS is a type of TS, mimicking acute coronary syndrome. It is seen in younger patients and often occurs with intense emotional and physical stress. Though many triggers have been reported, rTS associated with influenza A has not been previously documented.

We present a case of pyeloduodenal fistula in an 89-year-old woman with history of nephrolithiasis and recurrent urinary tract infection (UTI) who presented to the emergency department with back pain. CT revealed a malrotated right kidney with a large renal stone and possible fistulous connection between the second portion of the duodenum and the right renal collecting system. Technetium-99m scintigraphy confirmed presence of the fistula. The patient declined intervention and was discharged from the hospital with oral antibiotic suppressive therapy. The patient remained clinically stable at time of follow-up 3 months later. Spontaneous pyeloduodenal fistula is an aetiology of recurrent upper or lower UTIs or persistent bacteriuria though uncommonly recognised. Diagnosis may be achieved using several modalities, including technetium-99m scintigraphy. Nephrectomy and primary fistula closure has traditionally been the treatment of choice for this condition; however, conservative management is an option for patients with intact renal function.
