Aims Anaemia and iron deficiency are constituents of the cardio-renal syndrome in chronic heart failure (CHF). We investigated the effects of i.v. iron in iron-deficient CHF patients on renal function, and the efficacy and safety of this therapy in patients with renal dysfunction. Methods and results The FAIR-HF trial randomized 459 CHF patients with iron deficiency (ferritin <100 μg/L, or between 100 and 299 μg/L if transferrin saturation was <20%): 304 to i.v. ferric carboxymaltose (FCM) and 155 to placebo, and followed-up for 24 weeks. Renal function was assessed at baseline and at weeks 4, 12, and 24, using the estimated glomerular filtration rate (eGFR, mL/min/1.73 m2), calculated from the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula. At baseline, renal function was similar between groups (62.4 ± 20.6 vs. 62.9 ± 23.4 mL/min/1.73 m2, FCM vs. placebo). Compared with placebo, treatment with FCM was associated with an increase in eGFR [treatment effect: week 4, 2.11 ± 1.21 (P = 0.082); week 12, 2.41 ± 1.33 (P = 0.070); and week 24, 2.98 ± 1.44 mL/min/1.73 m2 (P = 0.039)]. This effect was seen in all pre-specified subgroups (P > 0.20 for interactions). No interaction between the favourable effects of FCM and baseline renal function was seen for the primary endpoints [improvement in Patient Global Assessment (P = 0.43) and NYHA class (P = 0.37) at 24 weeks]. Safety and adverse event profiles were similar in patients with baseline eGFR <60 and ≥60 mL/min/1.73 m2. Conclusions Treatment of iron deficiency in CHF patients with i.v. FCM was associated with an improvement in renal function. FCM therapy was effective and safe in CHF patients with renal dysfunction. © 2015 The Authors.

Background Previous evidence suggests that 25-hydroxyvitamin D3 [25(OH)D3] protects against several cancers. However, little is known regarding urothelial bladder cancer (UBC). We analyzed the association between plasma 25(OH)D3 and overall risk of UBC, as well as according to stage and FGFR3 molecular subphenotypes. Methods Plasma concentrations of 25(OH)D3 in 1125 cases with UBC and 1028 control subjects were determined by a chemiluminescence immunoassay. FGFR3 mutational status and expression in tumor tissue were assessed. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by logistic regression adjusting for potential confounders. Analyses were further stratified by tumor invasiveness and grade, FGFR3 expression, and smoking status. Cell proliferation was measured in human UBC cell lines cultured with 1α,25-dihydroxyvitamin D3. ResultsA statistically significantly increased risk of UBC was observed among subjects presenting the lowest concentrations of 25(OH)D3 (OR adj = 1.83; 95% CI = 1.19 to 2.82; P =. 006), showing a dose-response effect (Ptrend =. 004). The association was stronger for patients with muscle-invasive tumors, especially among low-FGFR3 expressers (OR adj = 5.94; 95% CI = 1.72 to 20.45; P =. 005). The biological plausibility of these associations is supported by the fact that, in vitro, 1α,25-dihydroxyvitamin D3 upregulates FGFR3 expression in UBC cell lines with low levels of wild-type FGFR3.ConclusionThese findings support a role of vitamin D in the pathogenesis of UBC and show that 25(OH)D3 levels are associated with FGFR3 expression in the tumor. Because FGFR3 mutation and overexpression are markers of better outcome, our findings suggest that individuals with low levels of plasma 25(OH)D3 may be at high risk of more aggressive forms of UBC. © 2012 The Author.

Fluoroscopy-induced chronic radiation dermatitis resulting from prolonged exposure to ionizing radiation during interventional procedures has been documented in the medical literature. However, this condition often requires a high clinical suspicion in order to establish a correct diagnosis. In this report, the development of deep scalp ulceration with bone exposure following the endovascular coiling of an anterior communicating artery aneurysm 8 years before is described. A skin biopsy specimen demonstrated changes consistent with chronic radiation dermatitis and ruled out malignancy. This case report expands the clinical manifestation spectrum of fluoroscopy-induced chronic radiation skin injury and highlights the importance of recognizing these lesions early to prevent morbidity related to radiation-induced skin damage.

In spite of recent advances in the treatment of metastatic breast cancer, this disease remains essentially incurable. Anthracyclines and taxanes have been widely demonstrated to be the most active cytotoxic drugs for the treatment of breast cancer. Paclitaxel and docetaxel are both hydrophobic drugs that need to be administered with detergent-like substances as solvents. In contrast, nanoparticle albumin-bound (nab) paclitaxel uses the natural characteristics of albumin to reversibly bind paclitaxel, transport it across endothelial cells and concentrate the active ingredient within the tumor. Several trials have demonstrated that nab-paclitaxel results in superior efficacy, with more complete responses, prolonged time to recurrence and survival, than paclitaxel and docetaxel in MBC. As second-line treatment, the novel formulation has almost doubled overall response rate, increased time to progression and overall survival in comparison with paclitaxel. Due to these results, to date nab-paclitaxel stands out as a promising treatment of metastatic breast cancer. © 2013.

Background: Borderline ovarian tumors (BOTs) are a subset of epithelial ovarian tumors with low malignant potential but significant risk of relapse (10% to 30%). Unfortunately, surgical prognostic factors for BOT relapse have not been clearly identified, probably due to the use of heterogeneous surgical definitions and limited follow-up. The aim of this study was to assess potential relapse risk factors using standard surgical definitions and long follow-up.Methods: All patients diagnosed with BOT for a period of more than 10 years in a single institution were included in the analysis. Complete surgical staging was defined as the set of procedures that follow standard guidelines for staging surgery (except lymphadenectomy), performed either with one or two interventions. Fertility-sparing surgeries that preserved one ovary and the uterus but included all the remaining procedures were classified as complete staging. The relationship between potential risk factors and time to BOT relapse was assessed by log-rank tests corrected for multiple comparisons and Cox regression.Results: Forty-six patients with a median follow-up of 5.4 years were included, of whom 91.3% had been diagnosed as FIGO stage I disease and 45.7% had received complete staging surgery. Five relapses were detected (10.9%), all of them in women who had been diagnosed with stage I disease and had received incomplete staging surgery. Log-rank tests confirmed the association between incomplete staging surgery and shorter time to BOT relapse.Conclusions: Complete staging surgery should be considered a cornerstone of BOT treatment in order to minimize the risk of relapse. © 2013 Romeo et al.; licensee BioMed Central Ltd.
