Abstract
Abstract
Background
Studies assessing whether heart failure (HF) is associated with an excess risk of cancer and cancer–related mortality yielded conflicting results. Here, we assessed the incidence and mortality of cancer according to the presence of HF in a community–based cohort.
Methods
By reviewing the health care records of the Puglia region in Italy, we first selected the individuals ≥50–year–old, with no history of cancer within 3 years before the baseline evaluation and ≥5 years of follow–up, during the period from January 1st, 2005 to December 31st, 2013. Next, we matched 1:1 104,020 subjects with HF at baseline and 104,020 controls based on age, sex, Drug–Derived Complexity Index, and follow–up duration. Cancer incidence and mortality were analyzed by Kaplan–Meier method and Cox regression models. Fine and Grey’s regression model was also used to compare cancer–specific mortality while taking into account the competing risk of non–cancer death.
Results
Overall, the mean age of the study population was 76±10 years and the mean follow–up was 5.7 years. The incidence rate of cancer in HF patients and controls was 21.36 (95%CI, 20.98–21.74) and 12.42 (95%CI, 12.14–12.72) per 1000 person/years, respectively, corresponding to a 76% higher risk of incident cancer in HF patients (HR, 1.76; 95%CI, 1.71–1.81). HF patients also died from cancer more frequently than controls (HR 4.11; 95%CI, 3.86–4.38; Figure 1). This excess mortality was highest when age was <70 years (HR 7.54, 95%CI 6.33–8.98), and declined in subjects aged 70–79 years (HR 3.80, 95%CI 3.44–4.19) and ≥80 years (HR 3.10, 95%CI 2.81–3.43). The association of HF with cancer mortality was confirmed in the competing risk analysis (subdistribution HR 3.48, 95%CI 3.27–3.72), as well as the interaction with age: <70 years of age: SHR 6.65, 95%CI 5.60–7.94; 70–80 years: SHR 3.14, 95%CI 2.84–3.48; and ≥80 years: SHR 2.81, 95%CI 2.55–3.10. The HF–related risk applied to the majority of cancer types. Interestingly, among HF patients a high consumption of loop diuretic (≥80 mg/d of furosemide equivalents for ≥30 days in the year before the index date) was associated with a higher mortality for cancer (HR 1.35, 95%CI 1.19–1.53 vs. ≤37.5 mg/d).
Conclusions
The analysis of this large community–based sample suggests that HF does portend an increased risk of cancer and cancer–related mortality, which is blunted, yet remains substantial, with increasing age and competing risk of dying from other causes.

The HF-related risk applied to the majority of cancer types, with the exception of neoplasm of the male reproductive system. Interestingly, among HF patients a high consumption of loop diuretic (>37.5 mg/d of furosemide) was associated with a higher mortality for cancer (HR 1.34, 95% CI 1.26–1.42 vs. ≤37.5 mg/d).
Conclusions
The analysis of this large community-based sample suggests that HF does portend an increased risk of cancer and cancer-related mortality, which is blunted, yet remains substantial, with increasing age and competing risk of dying from other causes. The risk of cancer may be heightened when HF is poorly compensated.

Abstract
Abstract
Background
Conflicting data exist regarding the risk of cancer in patients with heart failure (HF). It was first reported that incident cancer is more common among patients with than without HF, whereas more recent studies indicate that this association is primarily driven by comorbidities. HF, cancer, and comorbidities, such as chronic kidney disease (CKD) and chronic obstructive pulmonary disease (COPD), share numerous risk factors, including a state of chronic low-grade inflammation reflected by elevated circulating levels of pro-inflammatory cytokines. The objective of this analysis was to assess whether chronic low-grade inflammation, as measured by levels of high-sensitivity C-reactive protein (hsCRP), and comorbidities mediate the association of HF with incident cancer.
Methods
We used data from the 3rd wave of the Nord-Trøndelag Health Study (HUNT3), a population-based study that enrolled 50,803 individuals ≥18-year-old between October 2006 and June 2008 in the Nord-Trøndelag County (Norway), from the Cancer Registry of Norway and from the administrative health care records of the same region. Associations between baseline characteristics and the development of cancer were assessed using Cox proportional hazards regression models, using time from HUNT3 enrollment as the time scale. Analyses were performed using R statistical software, version 4.0.2.
Results
In HUNT3, hsCRP was measured in 47,571 individuals at the time of enrollment. Of these, we excluded 2,308 patients because of missing information, leaving a cohort of 45,263 subjects. Figure 1 shows the characteristics of the study population at baseline stratified by hsCRP tertiles. The prevalence of cardiovascular disease, comorbidities, and obesity was progressively higher with increasing concentrations of hsCRP.
During a median follow-up of 12 years, there were 66/408 cases of incident cancer in patients with HF at baseline and 5,024/47,163 in subjects without HF, with a more than 2-fold (HR 2.30; 95% CI 1.80–2.93; p<0.001) increase in risk of developing cancer. After adjusting for age and sex, the excess risk decreased to 43% (HR 1.43; 95% CI 1.12–1.82). When including hsCRP in the model, the HF-related risk of cancer was 33% (HR 1.33; CI 1.04–1.70; p=0.022). Furthermore, when body mass index, CKD, COPD, and smoking and drinking habits were included in the model, the risk of cancer in HF patients compared to individuals without HF was no longer significant (HR 1.23; 95% CI 0.94–1.60; p=0.127). Age, male sex, hsCRP, COPD, obesity, and smoking habits were all associated with an increased risk of cancer (Figure 2).
Conclusions
The increased risk of cancer in HF patients compared with the general population is at least in part explained by concomitant inflammation and comorbidities.

Multiscale Analysis of Metal Oxide Nanoparticles in Tissue: Insights into Biodistribution and Biotransformation. ADVANCED SCIENCE (WEINHEIM, BADEN-WURTTEMBERG, GERMANY) 2020; 7:2000912. [PMID: 32775166 PMCID: PMC7404155 DOI: 10.1002/advs.202000912] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/31/2020] [Revised: 04/22/2020] [Indexed: 05/05/2023]
Abstract
Metal oxide nanoparticles have emerged as exceptionally potent biomedical sensors and actuators due to their unique physicochemical features. Despite fascinating achievements, the current limited understanding of the molecular interplay between nanoparticles and the surrounding tissue remains a major obstacle in the rationalized development of nanomedicines, which is reflected in their poor clinical approval rate. This work reports on the nanoscopic characterization of inorganic nanoparticles in tissue by the example of complex metal oxide nanoparticle hybrids consisting of crystalline cerium oxide and the biodegradable ceramic bioglass. A validated analytical method based on semiquantitative X-ray fluorescence and inductively coupled plasma spectrometry is used to assess nanoparticle biodistribution following intravenous and topical application. Then, a correlative multiscale analytical cascade based on a combination of microscopy and spectroscopy techniques shows that the topically applied hybrid nanoparticles remain at the initial site and are preferentially taken up into macrophages, form apatite on their surface, and lead to increased accumulation of lipids in their surroundings. Taken together, this work displays how modern analytical techniques can be harnessed to gain unprecedented insights into the biodistribution and biotransformation of complex inorganic nanoparticles. Such nanoscopic characterization is imperative for the rationalized engineering of safe and efficacious nanoparticle-based systems.

'Green' Cr(iii)-glycine electrolyte for the production of FeCrNi coatings: electrodeposition mechanisms and role of by-products in terms of coating composition and microstructure. RSC Adv 2019; 9:25762-25775. [PMID: 35530084 PMCID: PMC9070400 DOI: 10.1039/c9ra04262h] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2019] [Accepted: 08/02/2019] [Indexed: 11/21/2022] Open
Abstract
The electrodeposition of stainless steel-like FeCrNi alloys for miniaturised devices is appealing as it would allow combining excellent material properties (e.g. corrosion resistance, hardness, biocompatibility) at low-cost. However, conventional baths often contain hazardous hexavalent chromium. Cr-based alloys electrodeposited from environmentally friendly trivalent chromium electrolytes are crucial for industrial application for facilitating the transition towards sustainable and ecological production and processing. Nevertheless, this process has not been comprehensively studied or understood in depth: especially the role of organic agents (common additives for improving Cr(iii)-based plating; e.g. glycine) in terms of material properties of the electrodeposits. The aim of this work was to investigate the electrodeposition of FeCrNi coatings from a ‘green’ Cr(iii)–glycine electrolyte. Novel information was attained by analysing films developed under various conditions and characterising them using a combination of advanced techniques. The evolution of microstructure (from amorphous to nanocrystalline) in correlation with film composition (i.e. metals ratio and presence of impurities) and elemental 3D spatial distribution was achieved for coatings produced from different anode materials and thermal post-treatment. The influence of Cr(iii) and glycine in terms of coating atomic contents (i.e. Fe–Cr–Ni–O–C–N–H) was evaluated for films in which both the applied current density and electrolyte composition were varied. These results, together with a thorough analysis on metals speciation/complexation allowed us to propose various Cr(iii)-based electroreduction mechanisms, and to observe, upon annealing, segregation and distribution of impurities, as well as of oxides and metals with respect to microstructure variation, providing an explanation for the amorphisation process. Electrodeposition mechanisms of a ‘green’ FeCrNi Cr(iii)–glycine electrolyte and their correlation with coatings' composition (metals/impurities), microstructure and elemental distribution variations.![]()

Abstract
Brazilian patients with benign prostatic hyperplasia were randomised in a 12-week, double-blind, double-dummy study to receive doxazosin gastrointestinal therapeutic system (GITS) 4 mg q.i.d. (n = 82) or tamsulosin 0.4 q.i.d. (n = 83). Primary endpoints were the absolute and percentage change from baseline in symptoms measured by International Prostate Symptom Score (IPSS). Secondary endpoints included IPSS, quality-of-life (QOL) question from the IPSS, and questions 6 and 7 of the Sexual Function Abbreviated Questionnaire (SFAQ) at weeks 4 and 12. Doxazosin GITS and tamsulosin improved IPSS with no significant differences between groups at week 12. During weeks 4-8, tamsulosin-treated patients demonstrated a slower improvement (p < 0.001) in IPSS than doxazosin GITS-treated patients. The proportion of satisfied patients was observed earlier with doxazosin GITS (p = 0.006) vs. tamsulosin. At week 12, the proportion of patients with little or no difficulty at ejaculation (Q6 of SFAQ) was higher in the doxazosin GITS group (p = 0.019). Both treatments were well tolerated.

Abstract
A 12-week, double-blind, placebo-controlled, multicenter study evaluated the efficacy and safety of flexible-dose sildenafil citrate (Viagra) treatment (25, 50 or 100 mg) in Brazilian and Mexican men with erectile dysfunction (ED) of broad-spectrum etiology. Efficacy was assessed on the basis of responses to the 15-item International Index of Erectile Function (IIEF) questionnaire, completed at baseline and after 12 weeks of treatment. At end point, mean scores for all IIEF domains of sexual function (erectile function, orgasmic function, sexual desire, intercourse satisfaction and overall satisfaction) were significantly (P<0.0001) higher in the sildenafil group (n=109) than in the placebo group (n=105). These findings confirm the significant increases in frequency of penetration and frequency of maintained erections reported previously. Sildenafil treatment was well tolerated. The most common adverse events were headache and flushing. In conclusion, sildenafil is a well-tolerated and effective treatment for ED of broad-spectrum etiology in Latin American men.
