DLT-based trading venues and EU capital markets legislation: state of the art and perspectives under the DLT pilot regime

This paper aims to analyze the interconnection of the recently published DLT Regulation with traditional pieces of EU financial legislation, particularly MiFID II and the CSDR, as to the treatment of market infrastructures. Therefore, the study’s main purpose is to scrutinize the legislative choices concerning the use of DLT in trading and settlement transactions, especially given the principle of technological neutrality. To reach such an objective, the paper briefly evaluates whether, and to what extent, the applicable legislation is indeed incompatible with DLT. As a result, questions are posed to the design of a pilot regime and to the short-term solution ultimately adopted by EU legislators, given the feasibility of more efficient coordination of the regimes in light of the new technology

Intermediate Alpha-1 Antitrypsin Deficiency Can Play a Role in Pulmonary Exacerbation?

Alpha-1 antitrypsin deficiency is generally suspected in young patients with pulmonary emphysema or chronic obstructive pulmonary disease (COPD). Patients often suffer from diagnostic delays or are misdiagnosed, for example, with COPD, asthma, or airway hyperresponsiveness because of the nonspecific nature of respiratory symptoms recognised with Alpha-1 antitrypsin deficiency (AATD). These pathologies develop in homozygous patients (both compromised alleles) with severely deficient protein; however, they are also frequently observed in heterozygous patients (only one compromised allele) for the gene mutation with a more or less deficient protein and functional anatomical damage of varying severity depending on the type of mutation and the exposure to environmental risk factors and/or professional that can trigger the repeated injurious inflammatory process. Case Description: We describe two cases of late diagnosis of alpha- 1 antitrypsin deficiency, with many exacerbations and intermediate level of alpha-1 antitrypsin. Due to the peculiar clinical history, and the PLowell rare mutation, although intermediate AATD, the patients were subjected to replacement therapy and they obtained clinical improvement. Discussion: Both the cases carried a heterozygous PLowell mutation representing two interesting and rare examples of clinical cases with double heterozygosity. The presence in the other AAT allele of the S- mutation in the first case and a concomitant presence of another mutation in the cystic fibrosis gene in the second case contributed to the protease-antiprotease imbalance and, despite intermediate AATD, was the probable cause of the numerous exacerbations. Conclusion: Alpha-1 antitrypsin deficiency should always be suspected in patients with respiratory disease and an unclear or complex clinical history. It may be useful to recognize and evaluate treatment even outside the established parameters, in selected cases

The emergency plan for the use and management of the territory

The issue of emergency planning in areas exposed to natural hazards cannot yet be considered as a focus within the scientific literature, probably because it has been judged as “too operative” for the interest of academic research. The topic of land use planning, spatial planning, and urban planning in risky areas, conversely, has gained attention in recent years. Nevertheless, the examples of good practices that involve ordinary master plans embedding mitigation concerns are still limited. &nbsp

Quality assessment of medical record as a tool for clinical risk management: a three year experience of a teaching hospital Policlinico Umberto I, Rome

Introduction: The medical record was defined by the Italian Ministry of Health in 1992 as "the information tool designed to record all relevant demographic and clinical information on a patient during a single hospitalization episode". Retrospective analysis of medical records is a tool for selecting direct and indirect indicators of critical issues (organizational, management and technical). The project’s aim being the promotion of an evaluation and self-evaluation process of medical records as a Clinical Risk Management tool to improve the quality of care within hospitals. Methods: The Authors have retrospectively analysed, using a validated grid, 1,184 medical records of patients admitted to the Teaching Hospital “Umberto I” in Rome during a three-year period (2013-2015). Statistical analysis was performed using SPSS for Windows © 19:00. All duly filled out criteria (92) were examined. “Strengths” and "Weaknesses" were identified through data analysis and Best and Bad Practice were identified based on established criteria. Conclusion: The data analysis showed marked improvements (statistically significant) in the quality of evaluated clinical documentation and indirectly upon behaviour. However, when examining some sub-criteria, critical issues emerge; these could be subject to future further corrective action

Fohotodermatoses and Skin Cancer

Preface Skin cancer is one of the most common types of tumors in Western countries. In the United States only, more than one million people are diagnosed with skin cancer each year. Although the absolute number of skin cancer patients is increasing, the death is inversely decreasing, due to the early detection and treatment. Basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma are three major types of skin cancer. BCC and SCC rarely have metastasis; over 95 percent BCC and SCC patients can be cured. Melanoma only accounts for a small percentage of skin cancer, but it causes 75 percent death of this disease. In this book, we invited a number of experts to present their latest accomplishments on skin cancer research. Although the topics are varied, the authors did great work to help readers better understand skin cancer and learn the knowledge to prevent this disease. There are three sections in this book, starting with etiology. Ultraviolet (UV) light exposure is overwhelmingly believed to be the most frequent cause of skin cancer. In this section, the association between UV and photodermatoses, as well as skin cancer is discussed. Desmosomal cadherins are important molecules in tumor cell adhesion and invasion, and their important roles in BCC are also presented in details. In the diagnosis and treatment section, a few new methodologies are described. As known, the outcome of malignant melanoma greatly depends on the thickness of the tumor at the time of treatment. Accurate determination of melanoma lateral and depth of margins using non-invasive imaging technologies is of importance when making sound decisions for treatment and evaluating a five year survival rate. A novel method named differential scanning calorimetry is capable of predicting metastasis of melanoma patients by monitoring the temperature changes of plasma. Electronic miniature X-ray brachytherapy is introduced as a new technology to treat nonmelanoms skin cancer. Although its potential has not yet been fully realized, chemoprevention, in terms of using chemical agents that naturally occur in foods, or are administered as pharmaceuticals to retard or reverse the process of carcinogenesis and progression of cancer, has been recognized to benefit individuals with precancerous lesions or genetic susceptibilities to cancer. In the prevention section, two chapters summarized the most recognized dietary phytochemicals and their potential application in skin cancer. X Preface This book would not have been possible without the contributions of all authors and the support from the publisher. Especially, I will convey my sincere appreciation to Ms. Tajana Jevtic, who has always been available and supportive of me to accomplish this project.

COVID-19 pneumonia and pulmonary microembolism in a patient with B-thalassemia major

We think that thalassemia is not necessarily a cause of aggravation of the clinical course in COVID-19; however, certain key factors must be considered, such as the anemic condition, the likely pathogenic role of the virus on hemoglobin, and the hypercoagulable state to prevent any complications
