Abstract
To evaluate the possible variations of adenosine receptor (AR) profile together with TNF-α and IL-6 mRNA in cardiac tissue of obese Zucker rats (OZR) during fasting conditions (fc) and during the induction of acute hyperglycemia (AH). OZR (O, n=21) and age-matched lean control rats (CO, n=18) were studied during fc (COfc, n=8; Ofc, n=13) and during the induction of AH (COAH, n=10; OAH, n=8). The histopathologic analysis performed on O and CO heart samples did not show abnormalities of myocardial structure. The AR transcriptomic profile was analyzed in O and CO by real-time polymerase chain reaction (PCR) and a significantly lower mRNA expression was observed for A2AR in O with respect to CO (p=0.047), while a significant upregulation was observed for A3R in O with respect to CO (p=0.002). No significant differences between O and CO were observed for TNF-α or IL-6. Correlations were found between glycemia and A1R (p=0.03) and A2BR (p=0.002); total cholesterol and A2BR (p=0.02) and A3R (p=0.0002), as well as between IL-6 and A1R (p=0.05) and TNF-α and A2AR (p<0.0001). The modulation of ARs in these settings could represent a promising approach to pharmacological treatment, which must be supported by diet restrictions and physical exercise.

Abstract
Background In end-stage heart failure (HF), the implantation of a left ventricular assist device (LVAD) is able to induce reverse remodeling. Cellular proteases, such as cathepsins, are involved in the progression of HF. The aim of this study was to evaluate the role of cathepsin system in HF patients supported by LVAD, in order to determine their involvement in cardiac remodeling. Methods The expression of cysteine (CatB, CatK, CatL, CatS) and serine cathepsin (CatG), and relative inhibitors (Cystatin B, C and SerpinA3, respectively) was determined in cardiac biopsies of 22 patients submitted to LVAD (pre-LVAD) and compared with: 1) control stable chronic HF patients on medical therapy at the moment of heart transplantation without prior LVAD (HT, n = 7); 2) patients supported by LVAD at the moment of transplantation (post-LVAD, n = 6). Results The expression of cathepsins and their inhibitors was significantly higher in pre-LVAD compared to the HT group and LVAD induced a further increase in the cathepsin system. Significant positive correlations were observed between cardiac expression of cathepsins and their inhibitors as well as inflammatory cytokines. In the pre-LVAD group, a relationship of cathepsins with dilatative etiology and length of hospitalization was found. Conclusions A parallel activation of cathepsins and their inhibitors was observed after LVAD support. The possible clinical importance of these modifications is confirmed by their relation with patients’ outcome. A better discovery of these pathways could add more insights into the cardiac remodeling during HF.

Abstract
BACKGROUND In left ventricular assist device (LVAD) recipients, plasma levels of interleukin (IL)-6 are associated with Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) profiles, reflecting post-operative risk. However, it is not clear how the cardiac level of IL-6, detectable on the tissue samples at the time of implantation, can contribute to predict the post-operative outcome. METHODS In 40 LVAD recipients, blood and myocardial samples from LV-apex were collected at the time of implantation to assess plasma and cardiac IL-6 levels. Serum C-reactive protein (CRP) levels were considered as inflammatory variable routinely used in LVAD-based therapy. RESULTS Cardiac IL-6 levels did not correlate with either plasma IL-6 levels (R=0.296, p=0.063) and tissue IL-6 mRNA expression (R=-0.013, p=0.954). Contrary to what happened for the plasma IL-6 and CRP, no differences were observed in cardiac IL-6 levels with respect to INTERMACS profiles (p=0.090). Furthermore, cardiac IL-6 concentrations, unlike IL-6 and CRP circulating levels, were not correlated with the length of intensive care unit stay and hospitalization. CONCLUSIONS Cardiac IL-6 levels do not contribute to improve risk profile of LVAD recipients in relation to clinical inpatient post-implantation. Instead, plasma IL-6 and serum CRP concentrations are more effective in predicting the severity of the clinical course in the early phase of LVAD therapy.

Abstract
BACKGROUND AND AIMS The deregulation of neurohormonal systems, including the natriuretic peptide (NP) and endothelin (ET) systems, may increase the possibility of developing obesity-related risk. The aim of our paper was to evaluate ET system mRNA variation in heart of the Zucker rat model together with the simultaneous evaluation of the NP system transcriptomic profile. In order to analyze the link between the ET-1 system and the inflammatory process, the cardiac expression of interleukin (IL)-6 and tumor necrosis factor (TNF)-α was also measured. METHODS AND RESULTS Zucker rats of 11-13 weeks were subdivided into obese rats (O, n = 20) and controls (CO, n = 20): half of them were studied under fasting conditions (CO(fc)-O(fc)) and the remainder after the induction of acute hyperglycemia (CO(AH)-O(AH)). Cardiac mRNA expression of TNF-α, IL-6, and NP/ET-1 systems was evaluated by Real-Time polymerase chain reaction. No significant difference for pre-proET-1, ET-A, and ET-B mRNA expression was detected between O and CO, whereas significantly lower mRNA levels of the ECE-1 were observed in O (p = 0.02). Regarding NPs, only BNP mRNA expression decreased significantly in O with respect to CO (p = 0.01). A down-regulation of NPR-B and NPR-C and an up-regulation of NPR-A were observed in O. No significant difference for IL-6 and TNF-α mRNA was revealed. Subdividing into fasting and hyperglycemic rats, many of the genes studied maintained their mRNA expression pattern almost unchanged. CONCLUSIONS The modulation of ET-1/NP systems in obesity could be a useful starting point for future studies aimed at identifying new therapeutic strategies for the treatment of cardiometabolic syndrome.

Abstract
BACKGROUND Caspase (Casp)-1 has been indicated as a molecular target capable of preventing the progression of cardiovascular diseases, including heart failure (HF), due to its central role in promoting inflammation and cardiomyocyte loss. The aim of this study was to assess whether Left Ventricular Assist Device (LVAD) implantation modifies the inflammatory and apoptotic profile in the heart through the modulation of Casp-1 expression level. METHODS Cardiac tissue was collected from end-stage HF patients before LVAD implant (pre-LVAD group, n=22) and at LVAD removal (post-LVAD, n=6), and from stable HF patients on medical therapy without prior circulatory support (HTx, n=7) at heart transplantation, as control. The cardiac expression of Casp-1, of its inhibitors caspase recruitment domain (CARD) only protein (COP) and CARD family, member 18 (ICEBERG), was evaluated by real-time PCR in the three groups of patients. RESULTS Casp-1 was increased in the pre-LVAD group compared to HTx (p=0.006), while on the contrary the ICEBERG level was significantly decreased in pre-LVAD with respect to HTx patients (p<0.001); no difference in COP expression level was found. CONCLUSIONS This study describes a specific pattern of the Casp-1 system associated with inflammation and apoptosis markers in patients who require LVAD insertion. The inflammation could be the key process regulating, in a negative loop, Casp-1 signaling and its down-stream effects, apoptosis included.

Abstract
BACKGROUND To evaluate the efficacy of prostate cancer (PCa) detection by the electronic nose (EN) on human urine samples. METHODS Urine samples were obtained from candidates of prostate biopsy (PB). Exclusion criteria were a history of urothelial carcinoma or other malignant disease, urine infection, fasting for <12 h before PB or ingestion of alcohol or foods that might alter the urine smell in the last 24 h. The initial part of the voided urine and the midstream were collected separately in two sterile containers. Both samples were analyzed by the EN immediately after the collection. All patients underwent a standard transperineal, transrectal-ultrasound-guided PB. The pathological results were compared with the outcomes of the EN. Sensitivity and specificity of EN were assessed. RESULTS Forty-one men were included in the study. Fourteen out of the 41 patients were positive for PCa. Midstream urine did not correlate significantly neither with a positive nor with a negative PB. Instead, significantly different results on the initial part of the urine stream between positive and negative PBs were obtained. The EN correctly recognized 10 out of the 14 cases (that is, sensitivity 71.4% (confidence interval (CI) 42-92%)) of PCa while four were false negatives. Moreover, the device recognized as negative 25 out of the 27 (that is, specificity 92.6% (CI 76-99%)) samples of negative PBs, with only two false positives. CONCLUSIONS We believe this is the first demonstration of an olfactory imprinting of the initial part of the urine stream in patients with PCa that was revealed by an EN, with high specificity.

Abstract
Cardiovascular disease (CVD) is the leading cause of death worldwide and the prevalence of obesity and diabetes are increasing. In obesity, adipose tissue increases the secretion of bioactive mediators (adipokines) that may represent a key mechanism linking obesity to CVD. Adiponectin, extensively studied in metabolic diseases, exerts anti-diabetic, anti-atherogenic and anti-inflammatory activities. Due to these positive actions, the role of adiponectin in cardiovascular protection has been evaluated in recent years. In particular, for its potential therapeutic benefits in humans, adiponectin has become the subject of intense preclinical research. In the cardiovascular context, understanding of the cellular and molecular mechanisms underlying the adiponectin system, throughout its secretion, regulation and signaling, is critical for designing new drugs that target adiponectin system molecules. This review focused on recent advances regarding molecular mechanisms related to protective effects of the adiponectin system on both cardiac and vascular compartments and its potential use as a target for therapeutic intervention of CVD.

Abstract
BACKGROUND The determination of matrix metalloproteases (MMPs) is relevant in many pathophysiological conditions, especially if associated with extracellular matrix remodeling; however, the results obtained are closely linked to the method used and are not directly comparable. The aim of this study was to perform a reappraisal of quantitative gel zymography technique for MMPs in human plasma, to use for comparison with commercially available ELISA and in those experimental conditions where the MMP active form needs to be revealed. METHODS The critical methodological parameters of zymography were checked and a comparison with a routinely used ELISA was performed. RESULTS Sensitivity and reproducibility levels of zymography are suitable for detection of MMP-9 in human plasma, providing results closely related to those obtained by ELISA. CONCLUSIONS Analytical parameters of zymography were suitable for detection of MMPs in human plasma. Quantitative zymography for MMPs is an alternative method for comparing the results of ELISA widely employed for MMP determination, thus reducing the discrepancies between laboratories regarding gelatinase assay.

Abstract
Patients with estrogen-receptor-positive advanced breast cancer are treated with endocrine therapy. The majority of breast cancer localizations show 18F-fluorodeoxyglucose (FDG) uptake at positron emission tomography (PET) examination. In these patients, the metabolic flare after therapy is common and was proposed as an index of therapy efficacy. Nevertheless, prolonged persistence of flare can lead to misinterpretation. We describe a case of a patient with invasive ductal breast cancer with bone metastases at bone scintigraphy and FDG PET scan and with expression of estrogen receptors. Initially, the patient underwent endocrine therapy in addition to a biphosfonate. Owing to progression observed in a bone scan, Tamoxifen was substituted with aromatase inhibitors. Successive bone scan examinations showed stabilization with a marked clinical improvement. A second FDG PET was performed 28 months after the first examination and showed a metabolic flare phenomenon with concomitant partial calcification of osteolitic lesions. This is an unusual case of prolonged metabolic flare.

Abstract
The aim of this prospective longitudinal multi centric study was to evaluate the correlation between the Hammersmith Functional Motor Scale and the 20 item version of the Motor Function Measure in non ambulant SMA children and adults at baseline and over a 12 month period. Seventy-four non-ambulant patients performed both measures at baseline and 49 also had an assessment 12 month later. At baseline the scores ranged between 0 and 40 on the Hammersmith Motor function Scale and between 3 and 45 on the Motor Function Measure 20. The correlation between the two scales was 0.733. The 12 month changes ranged between -11 and 4 for the Hammersmith and between -11 and 7 for the Motor Function Measure 20. The correlation between changes was 0.48. Our results suggest that both scales provide useful information although they appeared to work differently at the two extremes of the spectrum of abilities. The Hammersmith Motor Function Scale appeared to be more suitable in strong non ambulant patients, while the Motor Function Measures appeared to be more sensitive to capture activities and possible changes in the very weak patients, including more items capturing axial and upper limb activities. The choice of these measures in clinical trials should therefore depend on inclusion criteria and magnitude of expected changes.

Abstract
Meningioma is one of the most common spinal extramedullary tumors, largely intradural. An extradural localization is possible but less frequent. There are two morphologically different types of meningioma: one is round, and the other is the "en-plaque" form, that grows along the dura mater like a sheet. The "en-plaque" form, is unusual. We report on an unusual case of epidural and extraspinal "en-plaque" meningioma, describing the MRI and CT features and discussing the possible principal differential diagnosis (neurolymphomatosis, plexiform neurofibromas/schwannomas and metastasis).

Abstract
The aim of our longitudinal multicentric study was to establish the changes on the 6min walk test (6MWT) in ambulant SMA type III children and adults over a 12month period. Thirty-eight ambulant type III patients performed the 6MWT at baseline and 12months after baseline. The distance covered in 6min ranged between 75 and 510m (mean 294.91, SD 127) at baseline and between 50 and 611m (mean 293.41m, SD 141) at 12months. The mean change in distance between baseline and 12months was -1.46 (SD 50.1; range: -183 to 131.8m). The changes were not correlated with age or baseline values (p>.05) even though younger patients reaching puberty, had a relatively higher risk of showing deterioration of more than 30m compared to older patients. Our findings provide the first longitudinal data using the 6MWT in ambulant SMA patients.

D'Amico A, Fattori F, Bellacchio E, Catteruccia M, Servidei S, Bertini E. A new de novo missense mutation in MYH2 expands clinical and genetic findings in hereditary myosin myopathies. Neuromuscul Disord 2013; 23:437-40. [PMID: 23489661 PMCID: PMC3639366 DOI: 10.1016/j.nmd.2013.02.011] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2012] [Revised: 02/06/2013] [Accepted: 02/11/2013] [Indexed: 11/30/2022]
Abstract
Congenital myopathy related to mutations in myosin MyHC IIa gene (MYH2) is a rare neuromuscular disease. A single dominant missense mutation has been reported so far in a family in which the affected members had congenital joint contractures at birth, external ophthalmoplegia and proximal muscle weakness. Afterward only additional 4 recessive mutations have been identified in 5 patients presenting a mild non-progressive early-onset myopathy associated with ophthalmoparesis. We report a new de novo MYH2 missense mutation in a baby affected by a congenital myopathy characterized by severe dysphagia, respiratory distress at birth and external ophthalmoplegia. We describe clinical, histopathological and muscle imaging findings expanding the clinical and genetic spectrum of MYH2-related myopathy.
