I piani settoriali a scala urbana

Il contributo propone un focus su alcuni strumenti di settore che affrontano specifiche tematiche alla scala urbana, con particolare riferimento agli strumenti per la tutela della qualità ambientale e per il governo della mobilità. Si evidenziano, in entrambi i casi, le significative interrelazioni tra problematiche ambientali e scelte relative all’evoluzione/trasformazione dei contesti urbani e al governo della mobilità e la conseguente necessità di una più stretta integrazione tra strumenti generali e settoriali, difficilmente conseguibile attraverso il solo coordinamento a posteriori tra strumenti elaborati separatamente e sulla base di approcci settoriali

Clinical Trials with Mesenchymal Stem Cells: An Update:

In the last year, the promising features of mesenchymal stem cells (MSCs), including their regenerative properties and ability to differentiate into diverse cell lineages, have generated great interest among researchers whose work has offered intriguing perspectives on cell-based therapies for various diseases. Currently the most commonly used adult stem cells in regenerative medicine, MSCs, can be isolated from several tissues, exhibit a strong capacity for replication in vitro, and can differentiate into osteoblasts, chondrocytes, and adipocytes. However, heterogeneous procedures for isolating and cultivating MSCs among laboratories have prompted the International Society for Cellular Therapy (ISCT) to issue criteria for identifying unique populations of these cells. Consequently, the isolation of MSCs according to ISCT criteria has produced heterogeneous, nonclonal cultures of stromal cells containing stem cells with different multipotent properties, committed progenitors, and differentiated cells. Though the nature and functions of MSCs remain unclear, nonclonal stromal cultures obtained from bone marrow and other tissues currently serve as sources of putative MSCs for therapeutic purposes, and several findings underscore their effectiveness in treating different diseases. To date, 493 MSC-based clinical trials, either complete or ongoing, appear in the database of the US National Institutes of Health. In the present article, we provide a comprehensive review of MSC-based clinical trials conducted worldwide that scrutinizes biological properties of MSCs, elucidates recent clinical findings and clinical trial phases of investigation, highlights therapeutic effects of MSCs, and identifies principal criticisms of the use of these cells. In particular, we analyze clinical trials using MSCs for representative diseases, including hematological disease, graft-versus-host disease, organ transplantation, diabetes, inflammatory diseases, and diseases in the liver, kidney, and lung, as well as cardiovascular, bone and cartilage, neurological, and autoimmune diseases

Diastolic dysfunction and diastolic heart failure: diagnostic, prognostic and therapeutic aspects

Left ventricular (LV) diastolic dysfunction (DD) and diastolic heart failure (HF), that is symptomatic DD, are due to alterations of myocardial diastolic properties. These alterations involve relaxation and/or filling and/or distensibility. Arterial hypertension associated to LV concentric remodelling is the main determinant of DD but several other cardiac diseases, including myocardial ischemia, and extra-cardiac pathologies involving the heart are other possible causes. In the majority of the studies, isolated diastolic HF has been made equal to HF with preserved systolic function (= normal ejection fraction) but the true definition of this condition needs a quantitative estimation of LV diastolic properties. According to the position of the European Society of Cardiology and subsequent research refinements the use of Doppler echocardiography (transmitral inflow and pulmonary venous flow) and the new ultrasound tools has to be encouraged for diagnosis of DD. In relation to uncertain definitions, both prevalence and prognosis of diastolic heart failure are very variable. Despite an apparent lower death rate in comparison with LV systolic HF, long-term follow-up (more than 5 years) show similar mortality between the two kinds of HF. Recent studies performed by Doppler diastolic indexes have identified the prognostic power of both transmitral E/A ratio < 1 (pattern of abnormal relaxation) and > 1.5 (restrictive patterns). The therapy of LV DD and HF is not well established but ACE-inhibitors, angiotensin inhibitors, aldosterone antagonists and β-blockers show potential beneficial effect on diastolic properties. Several trials, completed or ongoing, have been planned to treat DD and diastolic HF

S14-01 Cognitive deficits in first episode schizophrenia

Cognitive deficits are increasingly recognized as key features of schizophrenia, important determinants of poor psychosocial outcome and targets for treatment strategies. The huge literature on the topic made it clear that cognitive impairment is present in the majority of subjects with schizophrenia, is not an epiphenomenon of symptoms, is a risk factor for psychotic disorders and seems to contribute to poor functional outcome more than symptoms. However, relationships of cognitive impairment with symptoms, drug treatment and duration of untreated psychosis remain controversial and studies involving large cohorts of first episode schizophrenia patients are highly needed to address these topics adequately. The European First Episode Schizophrenia Trial collected demographic, clinical, psychosocial and cognitive baseline data in 498 first episode patients with schizophrenia, schizophreniform or schizoaffective disorder, with minimal or no prior exposure to antipsychotics, and in 220 healthy subjects, comparable with patients for age, sex, race and education level of parents. Z scores of the examined cognitive abilities (number of standard deviations below the comparison group means) ranged from -0.88 to -1.73. No association was found between the duration of untreated psychosis and cognitive impairment. Psychopathological dimensions were weakly correlated with cognitive impairment both at baseline evaluation and after six months of treatment.According to EUFEST findings, cognitive impairment in patients with first-episode schizophrenia is moderate/severe, has no association with the duration of untreated psychosis, involves several domains of cognition, and is largely independent from psychopathology

A resilience-based approach to enhance the capacity of small villages to cope with intertwined threats: A Case-Study in the Basilicata Region

About 70 percent of Italian municipalities that have fewer than 5,000 inhabitants are located in difficult to access mountain areas which are often prone to multiple hazards. As clearly demonstrated by the seismic events that hit Central Italy in 2016, the socio-economic decline of these municipalities is also increasing their vulnerability. Nowadays, small villages represent an important challenge for Italy, because they require significant resources and effective strategies to both break the cycle of decline and promote their economic and social development, while also reducing their vulnerability to natural and climate related hazards. This contribution provides an overview of the initiatives recently launched in Italy in favour of small villages and outlines a methodological path to assess and enhance the overall resilience of these areas, with a focus on a case study area located in the Basilicata Region of Southern Italy
