Abstract
Hereditary hemochromatosis is an autosomal recessive disorder characterized by severe iron overload. It is usually associated with homozygosity for the HFE gene mutation c.845G > A; p.C282Y. However, in some cases, another HFE mutation (c.187C > G; p.H63D) seems to be associated with the disease. Its penetrance is very low, suggesting the possibility of other iron genetic modulators being involved. In this work, we have screened for HAMP promoter polymorphisms in 409 individuals presenting normal or increased serum ferritin levels together with normal or H63D-mutated HFE genotypes. Our results show that the hepcidin gene promoter TG haplotype, originated by linkage of the nc.-1010C > T and nc.-582A > G polymorphisms, is more frequent in the HFE_H63D individuals presenting serum ferritin levels higher than 300 μg/L than in those presenting the HFE_H63D mutation but with normal serum ferritin levels or in the normal control group.Moreover, it was observed that the TG haplotype was associated to increased serum ferritin levels in the overall pool of HFE_H63D individuals. Thus, our data suggest that screening for these polymorphisms could be of interest in order to explain the phenotype. However, this genetic condition seems to have no clinical significance.

Abstract
In addition to cognitive decline, Alzheimer's disease (AD) patients also exhibit an unexplained weight loss that correlates with disease progression. In young and middle-aged AD patients, large amounts of amyloid-β (Aβ) deposits were observed in the hypothalamus, a brain region involved in the control of feeding and body weight through the action of peripheral metabolic peptides, which have recently been shown to have neuroprotective effects. Moreover, levels of peripheral metabolic peptides, such as leptin and ghrelin, are changed in AD patients. The present study aimed to investigate the role of Aβ peptide in the survival of hypothalamic cells and to explore the receptor-mediated protective effect of leptin and ghrelin against Aβ-induced toxicity in these cells. Using the mHypoE-N42 cell line, we demonstrated for the first time that oligomeric Aβ is toxic to hypothalamic cells, leading to cell death. It was also demonstrated that leptin and ghrelin protect these cells against AβO-induced cell death through the activation of the leptin and ghrelin receptors, respectively. Furthermore, ghrelin and leptin prevented superoxide production, calcium rise and mitochondrial dysfunction triggered by AβO. Taken together, these results suggest that peripheral metabolic peptides, in particular leptin and ghrelin, might be considered as preventive strategies for ameliorating hypothalamic alterations in AD.

Abstract
Background: Prostate cancer mortality has been decreasing in several high income countries and previous studies analysed the trends mostly according to geographical criteria. We aimed to identify patterns in the time trends of prostate cancer mortality across countries using a model-based approach. Methods: Model-based clustering was used to identify patterns of variation in prostate cancer mortality (1980–2010) across 37 European, five non-European high-income countries and four leading emerging economies. We characterised the patterns observed regarding the geographical distribution and gross national income of the countries, as well as the trends observed in mortality/incidence ratios. Results: We identified three clusters of countries with similar variation in prostate cancer mortality: pattern 1 (‘no mortality decline'), characterised by a continued increase throughout the whole period; patterns 2 (‘later mortality decline') and 3 (‘earlier mortality decline') depict mortality declines, starting in the late and early 1990s, respectively. These clusters are also homogeneous regarding the variation in the prostate cancer mortality/incidence ratios, while are heterogeneous with reference to the geographical region of the countries and distribution of the gross national income. Conclusion: We provide a general model for the description and interpretation of the trends in prostate cancer mortality worldwide, based on three main patterns.

Abstract
INTRODUCTION The prevalence of malnutrition in ambulatory patients with heart failure is difficult to determine, depending on the timing and methodology. OBJECTIVE To determine the nutritional status of outpatients with systolic heart failure with the Mini Nutritional Assessment (MNA) full and short-form versions, and evaluate its relationship with the short-term prognosis, biomarkers and quality of life. METHODS Fifty consecutive (70% male), geriatric (74.3+ 6.2years old) stable outpatient with heart failure (NYHA class II 68%, III 32%) and left ventricular ejection fraction of 26.7 +11.5% were included and followed during 12 months. At a routine visit to the heart failure clinic, the MNA, the Minnesota Living with Heart Failure questionnaire (MLHFQ) were applied. According to the MNA screening score the nutritional status was classified using the MNA full (MNA-F) and the short-form (MNA-F) versions of the questionnaire. The recorded events were death and hospitalization. STATISTICS The survival and hospitalizations curves were evaluated with the Log-Rank test and Cox Regression analysis. The association between parameters was analyzed with the Pearson and Spearmann correlation coefficient. RESULTS (1) The mortality and hospitalization rates were 12% and 42%, respectively. (2) With the MNA-SF 7.6% of the patients had malnutrition and 20% were at risk of malnutrition. There was a good agreement (90%) between the MNA-SF and the MNA-F classifications. (3) There was a significant relationship between the MNA screening score and the MLHFQ (rs= -0.592 p<0.001), Nt-ProBNP (rs= -0.49 p<0.001) and total plasma protein (r= 0.672 p=0.006); (3) The MNA-SF nutritional classification was associated with the 12 months survival (Log-Rank p=0.044) and hospitalization (Log-Rank p=0.005) curves. (4) Those patients with malnutrition by the MNA-SF were at greater risk of death (HR= 8.0 p=0.059) and hospitalization (HR 8.1 p=0.008). CONCLUSION The MNA is useful for the evaluation of the nutritional status of elderly outpatients with systolic heart failure. It is a good predictor of the short-term outcome and is also associated with the quality of life and Nt-ProBNP.

Abstract
AIM To evaluate in vivo the performance of the iPex and Root ZX electronic apex locators (EALs) in the presence of several irrigant solutions: 2.5% sodium hypochlorite (NaOCl) and 2% chlorhexidine (CHX). METHODOLOGY Thirty-two single-rooted human teeth that were scheduled for extraction were selected. Teeth with metallic restorations, fractures, root resorption, pulp necrosis or open apices were not included The working length (WL) was determined electronically for the root canals with the iPex and Root ZX EALs in the presence of two different irrigant solutions, 2.5% NaOCl and 2% CHX. After the teeth had been extracted, a size 10 K-file was used to determine the reference working length (RWL), which was established at 0.5 mm short of the major foramen. In each case, the RWL was subtracted from the electronic measurements. Positive values indicated electronic measurements that exceeded the RWL (long measurements), whereas negative values indicated measurements that were short of the RWL. The values obtained with the different irrigants and EALs were compared using the paired t-test. Significance was set at P < 0.05. RESULTS The accuracy of the iPex nor Root ZX EAL was not affected by 2.5% NaOCl or 2% CHX (P > 0.05). However, significant differences were observed between the readings of the iPex and Root ZX, irrespective of whether 2.5% NaOCl or 2% CHX was used as the irrigant (P < 0.05). The iPex was less accurate than the Root ZX in determining the RWL. CONCLUSIONS The accuracy of neither the iPex nor Root ZX EAL was affected by the irrigant used. However, the iPex was less accurate than the Root ZX in determining the RWL both for 2.5% NaOCl and for 2% CHX.
