Family Problems. Debates over Coupling, Marriage, and Family within the Italian Lesbian Community, 1990s

In the European context, Italy is currently an anomaly. It has no legislative instrument with which to regulate same sex relationship , despite the fact that in the last twenty-five years the Italian LGBTIQ movement (at least in its mainstream manifestation) has continued to call for a law on the subject (civil partnerships, regulation of de facto cohabitation, PACS, and marriage, are a handful of the solutions that have been proposed). In the political elaboration of certain radical sectors of the movement there has been an attempt to critique, or at least question, the imaginaries produced by the investment in the gay family. There has never been a stage of the Italian LGBTIQ movement in which positions regarding the concept of the family were homogeneous. Instead often it was precisely regarding this issue that the radical or reformist dialectic contrasted

Predictive Echocardiography

In this thesis multiple echocardiographic approaches and techniques to predict clinical and functional outcome were evaluated. The value of high-dose dobutamine stress echocardiography for the prediction of longterm cardiac events was evaluated in various clinical settings in patients with known or suspected coronary artery disease. Low-dose dobutamine stress echocardiography and tissue Doppler imaging were used to evaluate myocardial viability and left ventricular remodelling in patients with ischemic cardiomyopathy who underwent myocardial revascularization or percutaneous transplantation of skeletal myoblasts. The value of myocardial contrast echocardiography was studied to predict functional recovery in patients with acute myocardial infarction who underwent primary coronary intervention. Next, resting 2-D echocardiography was used to predict the onset of dilated-hypokinetic evolution and cardiovascular events in patients with hypertrophic cardiomyopathy. Finally, the role of intracardiac echocardiography was investigated for prediction of the infarct area in patients with obstructive hypertrophic cardiomyopathy who underwent percutaneous septal myocardial ablation

Neuroactive Peptides as Putative Mediators of Antiepileptic Ketogenic Diets

Various ketogenic diet (KD) therapies, including classic KD, medium chain triglyceride administration, low glycemic index treatment, and a modified Atkins diet, have been suggested as useful in patients affected by pharmacoresistant epilepsy. A common goal of these approaches is to achieve an adequate decrease in the plasma glucose level combined with ketogenesis, in order to mimic the metabolic state of fasting. Although several metabolic hypotheses have been advanced to explain the anticonvulsant effect of KDs, including changes in the plasma levels of ketone bodies, polyunsaturated fatty acids, and brain pH, direct modulation of neurotransmitter release, especially purinergic (i.e., adenosine) and γ-aminobutyric acidergic neurotransmission, was also postulated. Neuropeptides and peptide hormones are potent modulators of synaptic activity, and their levels are regulated by metabolic states. This is the case for neuroactive peptides such as neuropeptide Y, galanin, cholecystokinin and peptide hormones such as leptin, adiponectin, and growth hormone-releasing peptides (GHRPs). In particular, the GHRP ghrelin and its related peptide des-acyl ghrelin are well-known controllers of energy homeostasis, food intake, and lipid metabolism. Notably, ghrelin has also been shown to regulate the neuronal excitability and epileptic activation of neuronal networks. Several lines of evidence suggest that GHRPs are upregulated in response to starvation and, particularly, in patients affected by anorexia and cachexia, all conditions in which also ketone bodies are upregulated. Moreover, starvation and anorexia nervosa are accompanied by changes in other peptide hormones such as adiponectin, which has received less attention. Adipocytokines such as adiponectin have also been involved in modulating epileptic activity. Thus, neuroactive peptides whose plasma levels and activity change in the presence of ketogenesis might be potential candidates for elucidating the neurohormonal mechanisms involved in the beneficial effects of KDs. In this review, we summarize the current evidence for altered regulation of the synthesis of neuropeptides and peripheral hormones in response to KDs, and we try to define a possible role for specific neuroactive peptides in mediating the antiepileptic properties of diet-induced ketogenesis

Restrictive cardiomyopathy and hypertrophic cardiomyopathy overlap: the importance of the phenotype

Restrictive cardiomyopathy (RCM) is defined on the basis of the haemodynamic finding of restrictive ventricular physiology. However, restrictive ventricular pathophysiology is also a feature of other subtypes of cardiomyopathy, including hypertrophic cardiomyopathy (HCM). Clinically and aetiologically, there is an overlap between RCM and HCM with restrictive physiology. However, the clinical distinction between these two entities can be an important pointer towards the underlying aetiology. This review highlights the importance of the recognition of the clinical phenotype as the first step in the classification of cardiomyopathies

Antithrombotic Management during Percutaneous Mitral Valve Repair with the Mitraclip System in a Patient with Heparin-Induced Thrombocytopenia

Interventional cardiology procedures require full anticoagulation to prevent thrombus formation on catheters and devices with potential development of embolic complications. Bivalirudin, a short half-life direct thrombin inhibitor, has been largely used during percutaneous coronary interventions and represents the preferred alternative to heparin in patients with heparin-induced thrombocytopenia (HIT). However, few data are available about intraprocedural use of bivalirudin during transcatheter structural heart disease interventions. Activated clotting time (ACT) monitoring during bivalirudin infusion pre- sents some limitations and it is not mandatory. We report a case of bivalirudin use in a patient with type-2 HIT during percutaneous mitral valve repair with the Mitraclip system (Abbott, Abbott Park, Illinois, United States). Despite use of standard bivalirudin dose (0.75 mg/kg bolus and 1.4 mg/kg/min infusion—reduced infusion rate was motivated by a glomerular filtration rate of 37 mL/min), the patient developed a large thrombus on the second clip during its orientation toward the mitral orifice. ACT was measured at that time and was suboptimal (240 seconds). The case was successfully managed with clip and thrombus retrieval, adjunctive 0.3 mg/kg bivalirudin bolus and increased infusion rate, and clip repositioning with ACT monitoring. This report makes the case for mandatory ACT checking and drug titration during high-risk catheter–based structural heart disease interventions, even when thromboprophylaxis is performed with bivalirudin. Additional coagulation tests may be useful to monitor bivalirudin response in similar cases

Dilated-Hypokinetic Evolution of Hypertrophic Cardiomyopathy Prevalence, Incidence, Risk Factors, and Prognostic Implications in Pediatric and Adult Patients

ObjectivesThis study sought to investigate the incidence, risk factors, and prognosis of dilated-hypokinetic evolution in a large cohort of patients with hypertrophic cardiomyopathy (HCM) followed up at a cardiology center serving both the pediatric and the adult population.BackgroundThe available data on this evolution of HCM mainly regards prevalence (rather than incidence) in adults, with very little being known about the pediatric population.MethodsA total of 222 consecutive HCM patients (65% men, 19% ≤18 years old) were prospectively evaluated for a mean follow-up of 11 ± 9 years.ResultsA diagnosis of dilated-hypokinetic HCM was made in 12 patients at first evaluation (11 without previous septal myectomy surgery; prevalence, 4.9%). Twelve of the 210 patients with classic HCM at first evaluation underwent dilated-hypokinetic evolution (incidence, 5.3/1,000 patient-years). Patients with prevalent/incident dilated-hypokinetic evolution were younger at first evaluation (32 ± 14 years vs. 41 ± 21 years, p = 0.04) and more often had a family history of HCM (61% vs. 26%, p = 0.002) or sudden death (43% vs. 19%, p = 0.01) with respect to patients who maintained classic HCM. Moreover, they showed greater interventricular septum (23 ± 3 mm vs. 19 ± 6 mm, p = 0.004) and posterior wall (15 ± 3 mm vs. 13 ± 4 mm, p = 0.006) thickness. Cardiovascular death-free survival was lower among patients with dilated-hypokinetic HCM (p < 0.04). Cox proportional hazards regression analysis identified left ventricular wall thickness (hazard ratio [HR] = 1.07; 95% confidence interval [CI], 1.01 to 1.14; p = 0.03) and end-diastolic diameter (HR = 1.08; 95% CI 1.04 to 1.11; p = 0.0001) as independent predictors of cardiovascular death.ConclusionsDilated-hypokinetic evolution is rare but not exceptional in HCM. Young age at diagnosis, family history of HCM, and greater wall thickness are incremental risk factors for dilated-hypokinetic HCM, which carries an ominous prognosis

A cost-effectiveness analysis of hypertrophic cardiomyopathy sudden cardiac death risk algorithms for implantable cardioverter defibrillator decision-making

AIMS: To conduct a contemporary cost-effectiveness analysis examining the use of implantable cardioverter defibrillators (ICD) for primary prevention in patients with hypertrophic cardiomyopathy (HCM). METHODS: A discrete-time Markov model was used to determine the cost-effectiveness of different ICD decision-making rules for implantation. Several scenarios were investigated including the reference scenario of implantation rates according to observed real world practice. A 12-year time horizon with an annual cycle length was used. Transition probabilities used in the model were obtained using Bayesian analysis. The study has been reported according to the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist. RESULTS: Using a 5-year SCD risk threshold of 6% was cheaper than current practice and has marginally better total quality adjusted life years (QALYs). This is the most cost-effective of the options considered, with an incremental cost effectiveness ratio of £834 per QALY. Sensitivity analyses highlighted that this decision is largely driven by what health related quality of life (HRQL) is attributed to ICD patients and time horizon. CONCLUSION: We present a timely new perspective on HCM ICD cost-effectiveness, using methods reflecting real-world practice. While we have shown that a 6% 5-year SCD risk cut-off provides the best cohort stratification to aid ICD decision-making, this will also be influenced by the particular values of costs and HRQL for subgroups or at a local level. The process of explicitly demonstrating the main factors which drive conclusions from such an analysis will help to inform shared decision-making in this complex area for all stakeholders concerned
