Directory of Armenian and Assyrian Churches in the villages of the Salmas and Khoy Counties
No full textThe directory gives a detailed account of 23 churches surveyed in the counties of Salmas, Khoy and Urmia, chosen from the 29 visited from 2016 to 2018 because they still retain a recognisable architectural conformation that characterised them, although many of them are now in a state of ruin. For each of them a sheet has been drawn up detailing the period of construction, the planimetric layout, the description and the state of conservation, defining the main problems but also the possibilities for reuse and enhancement. Where possible, the current state is compared with that found in the 1970s during the missions of Adriano Alpago Novello (1976, 1977)
Foreword. Toward protection, conservation and reuse of architectural and landscape heritage
No full textThe book is about the history of Protection and Restoration in Iran, and particularly in Iranian Western Azerbaijan. A substantial part of the volume is dedicated to illustrating how the territory of the cities of Khoy and Salmas has been described in the reports of Western travelers. Finally, several essays are dedicated to the study of the Armenian and Assyrian churches still present in this area, evaluating the problems of their protection and conservation
Christian Churches in Salmas, Khoy and Urmia Counties. Conservation problems and enhancement perspectives in Cultural and territorial context of Western Azerbaijan
No full textThe territory of Salmas, Khoy and Urmia counties still preserves traces of the strong presence of the Armenian community and the churches they built to practise their faith.
Damaged by the strong earthquake that shook the area in 1930, and no longer used for worship because the Armenian communities are no longer present, they are now often in a state of ruin. During three successive missions (2016, 2017, 2018), 22 villages and 29 churches were visited.
The paper describes their current state of preservation, highlighting the problems of degradation and instability that afflict them, with the aim of outlining possible solutions and defining strategies for their new use in line with the needs of the communities that now inhabit the area
Architectural Heritage in the Western Azerbaijan Province of Iran. Evidence of an Intertwining of Cultures
No full textThe book is about the history of protection and restoration in Iran, and particulary in Iranian Wester Azerbaijan. A substantial part of the volume is dedicated to illustrating how the territory of the cities of Khoi and Samas has been described in the reports of Western travelers. Finally, several essays are dedicated to the study of the Armenian and Assyrian churches still present in this area, evaluating the problems of their protection and conservation
Obesity Paradox in Atrial Fibrillation: Implications for Outcomes and Relationship with Oral Anticoagulant Drugs
No full textIn the last 40 years, concern about the obesity epidemic has increased. Data from the current literature highlight a strong relationship between obesity and atrial fibrillation (AF), particularly in relation to an increased risk for incident and recurrent AF. A phenomenon called the “obesity paradox” has emerged: the apparently counterintuitive evidence from epidemiological data indicating that overweight and obese patients may have a better prognosis than healthy-weight patients. A differential impact of oral anticoagulants (OACs) in terms of effectiveness and safety in the various body mass index categories has been postulated, particularly in the comparison between non-vitamin-K antagonist oral anticoagulants and vitamin K antagonists. This review aims to summarize the evidence on the impact of obesity in patients with AF, focusing on descriptions of the obesity paradox and its relationships with OAC treatment
La tachicardiomiopatia: una revisione della letteratura
No full textA fast heart rate or an irregular ventricular rhythm can produce various degrees of functional impairment and structural remodeling of the ventricle referred to as tachycardia-related cardiomyopathy or tachycardiomyopathy. This form of myocardial dysfunction can be caused by supraventricular or ventricular tachyarrhythmias that are incessant and associated with ventricular rates higher than 120 bpm. It can be reversed with pharmacological or nonpharmacological rate control or arrhythmia reversion. The prevalence of ventricular and supraventricular tachyarrhythmias is high among patients with heart failure. Consequently, in clinical settings, it may be difficult to determine whether a patient with severe ventricular dysfunction and supraventricular tachyarrhythmia associated with a rapid ventricular response is suffering from tachycardiomyopathy or from heart failure complicated by the subsequent development of a supraventricular tachyarrhythmia (e.g. atrial fibrillation). This typical "chicken-or-the-egg" dilemma can be resolved by treating the arrhythmia (pharmacological or nonpharmacological rate and/or rhythm control) and closely monitoring the evolution of the left ventricular dysfunction. Proper management of tachycardiomyopathy requires appropriate decision making, use of both pharmacological and nonpharmacological treatment approaches, and close follow-up. The purpose of this review article is to examine currently available data (experimental and clinical) on this complex clinical entity and on rate-control therap
Early or Delayed Cardioversion in Recent-Onset Atrial Fibrillation
No full textTo the Editor: Pluymaekers et al. (April 18 issue)(1) evaluated the occurrence of spontaneous cardioversion in patients with recent-onset (<36 hours) atrial fibrillation. The proposed wait-and-see approach included cardioversion within 48 hours in the absence of spontaneous resumption of sinus rhythm, and delayed cardioversion was actually necessary in 28% of the patients randomly assigned to this strategy. We think that the idea of waiting for spontaneous cardioversion of atrial fibrillation is interesting, but for practical reasons, better patient targeting would be required. In two previous prospective, randomized trials, we found that in patients with recent-onset atrial fibrillation, spontaneous cardioversion can . .
