- Both hyperkalemia and hypokalemia may be related to heart failure (HF) therapy and are associated with adverse outcomes. Abnormalities in serum potassium levels in hospitalized patients with HF and reduced ejection fraction (EF) have not been previously investigated. A post hoc analysis was performed in 1,907 hospitalized patients with worsening HF and reduced EF in the placebo arm of the Efficacy of Vasopressin Antagonism in HF Outcome Study with Tolvaptan (EVEREST) trial. Serum potassium was measured at randomization and at discharge or day 7. The co-primary end points were all-cause mortality (ACM) and cardiovascular mortality or the first HF hospitalization (CVM + HFH). The association between inhospital change in potassium levels and time to outcomes was evaluated using multivariate Cox regression models. Study participants had a mean age of 65.6 +/- 12.0 years and were on optimal guideline-directed medical therapies, including beta blockers (77%), angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (85%), and aldosterone antagonists (55%). Baseline potassium concentration was 4.3 +/- 0.6 mEq/l, and hyperkalemia or hypokalemia was seen in 6.5% of the participants. On average, serum potassium level increased by 0.21 +/- 0.66 mEq/l, p < 0.0001, during hospitalization. Inhospital potassium change was not associated with either the primary or the secondary end point over a median follow-up of 9.9 months. In conclusion, in patients with reduced EF hospitalized for worsening HF, serum potassium abnormalities are common at baseline (within 48 hours of admission) and potassium levels increase during hospitalization, despite aggressive diuretic therapy. However, they are not associated with all-cause or CVM or HFH. Inhospital changes in potassium may limit the implementation of evidence-based therapies such as mineralocorticoid receptor antagonists.

- BACKGROUND: Anemia has been associated with worse outcomes in patients with chronic heart failure (HF). We aimed to characterize the clinical profile and postdischarge outcomes of hospitalized HF patients with anemia at admission or discharge. METHODS AND RESULTS: An analysis was performed on 3731 (90%) of 4133 hospitalized HF patients with ejection fraction 100 days) on adjusted analysis (both P>0.1). CONCLUSIONS: Among hospitalized HF patients with reduced ejection fraction, modest anemia at discharge but not baseline was associated with increased all-cause mortality and short-term cardiovascular mortality plus HF hospitalization.

- AIMS: We evaluated the impact of diabetes mellitus (DM) and diabetic therapy on outcomes in patients with reduced ejection fraction (EF) after hospitalization for heart failure (HF). DM is prevalent in patients hospitalized with HF, yet inconclusive data exist on the post-discharge outcomes of this patient population. METHODS AND RESULTS: Post-hoc analysis was performed on the EVEREST (Efficacy of Vasopressin Antagonism in Heart Failure Outcome Study with Tolvaptan) study, a randomized trial of patients hospitalized with HF (n = 4133) with median follow-up of 9.9 months. DM status was determined from intake questionnaires and cross-verified by medication history. Univariate relationships were examined using chi(2) test, t-test, and Wilcoxon tests. The two primary outcomes of (i) all-cause mortality (ACM) and (ii) cardiovascular mortality or HF hospitalization (CVM + HFH) were assessed for those with and without DM and by diabetic treatment strategy using log rank tests and multivariable Cox regression models. DM was present in 40% of participants. Patients with DM were more likely to have hypertension, coronary artery disease, and chronic kidney disease. Diabetes was associated with ACM and CVM + HFH (both P < 0.001). Following multivariate risk adjustment, DM was associated with ACM, but this estimate was imprecise [hazard ratio (HR) 1.16; 95% confidence interval (CI) 1.00-1.34] and remained associated with CVM or HFH (HR 1.17; 95% CI 1.04-1.31). Diabetic control strategy did not independently affect outcomes. CONCLUSION: Diabetes is common in patients hospitalized for heart failure with a reduced EF. These patients have a higher post-discharge CVM and higher HF hospitalizations compared with patients with no diabetes. Different diabetic treatment regimens did not appear to influence post-discharge outcomes.

- Background—Low lymphocyte count has been shown to be an independent prognostic marker in heart failure (HF) in the outpatient setting. Limited data exist regarding whether relative lymphocyte count correlates with postdischarge outcomes in patients hospitalized for HF. Methods and Results—We performed a post hoc analysis of the Efficacy of Vasopressin Antagonism in Heart Failure Outcome Study with Tolvaptan (EVEREST) trial, which randomized 4133 patients hospitalized for worsening HF with an ejection fraction ≤40% within 48 hours of admission to tolvaptan or placebo for a median follow-up of 9.9 months. The primary end points of all-cause mortality and cardiovascular mortality or HF hospitalization were analyzed in patients with available baseline complete blood counts (n=3717). Lymphocyte percentage was analyzed as a continuous variable. Times to events were compared using log-rank tests and multivariable Cox regression models. Patients with low lymphocyte percentage tended to be older and had higher rates of comorbid disease (diabetes mellitus, atrial fibrillation, and renal insufficiency). Low lymphocyte counts were associated with wide QRS duration, high natriuretic peptides, and low ejection fraction, blood pressure, and serum sodium. These patients were less likely to receive evidence-based HF medications. After adjusting for 22 known clinical risk factors, a 10% decrease in lymphocytes was associated with an increased hazard of all-cause mortality (adjusted hazard ratio 1.31 [95% CI: 1.14–1.150], P<0.001) and cardiovascular mortality or HF hospitalization (adjusted hazard ratio 1.14 [95% CI: 1.04–1.25], P=0.007) in the first 100 days postdischarge. Lymphopenia during hospitalization normalizes in majority of patients in the early postdischarge period. Conclusions—Low relative lymphocyte count during hospitalization for HF is an independent predictor of poor outcomes in the early postdischarge period, beyond traditional prognostic indicators.

- © 2019 Elsevier B.V. A complementary multi-analytical in-situ approach has been adopted for the investigation of a corpus of ten paintings dating from 1889 and 1940 by the Venetian painter Alessandro Milesi (1856–1945), from the collection of the International Gallery of Modern Art Ca’ Pesaro in Venice. Analyses were performed in situ with digital imaging, elemental and spectroscopic analysis. The analysis of pigments and binding media and their possible deterioration patterns were studied with a combination of X-Ray Fluorescence (XRF) Spectroscopy, External Reflection- Fourier Transform Infrared Spectroscopy (ER-FTIR) and Raman Spectroscopy. These analytical methods provide information regarding the evolution of the artist's palette and the painting techniques adopted in painting. Data suggest the widespread detection of zinc carboxylates, with implications for conservation and display.
