For Your Freedom and Ours: The Polish Question in Wilson's Peace Initiatives, 1916 - 1917

The first eighteen months of the Great War witnessed an unprecedented awakening of interest in the Polish Question, when worldwide attention was drawn to the prolonged devastation of the Polish territories. Thereafter, a steady increase in media comment and criticism, highlighting Poland's plight, fostered public indignation at the continual stalling of humanitarian relief efforts for Polish refugees. Such burgeoning popular sentiment focused wider political attention upon a growing movement for recognition of Polish claims to independence. This particularly proved to be the case for Woodrow Wilson and his administration's budding interest in Poland. Subsequently, nowhere did the Polish Question assume a greater role in diplomatic efforts to mediate for peace than in America, and at no time more than during the year preceding the President's hesitant decision to intervene in hostilities.

Ventricular dysfunction in early diabetic heart disease: detection, mechanisms and significance

The detection of preclinical heart disease is a new direction in diabetes care. This comment describes the study by Vinereanu and co-workers in this issue of Clinical Science in which tissue Doppler echocardiography has been employed to demonstrate subtle systolic and diastolic dysfunction in Type 11 diabetic patients who had normal global systolic function and were free of coronary artery disease. The aetiology of early ventricular dysfunction in diabetes relates to complex intramyocardial and extramyocardial mechanisms. The initiating event may be due to insulin resistance, and involves abnormal myocardial substrate utilization and uncoupling of mitochondrial oxidative phosphorylation. Dysglycaemia plays an important role via the effects of oxidative stress, protein kinase C activation and advanced glycosylation end-products on inflammatory signalling, collagen metabolism and fibrosis. Extramyocardial mechanisms involve peripheral endothelial dysfunction, arterial stiffening and autonomic neuropathy. The clinical significance of the ventricular abnormalities described is unknown. Confirmation of their prognostic importance for cardiac disease in diabetes would justify routine screening for presymptomatic ventricular dysfunction, as well as clinical trials of novel agents for correcting causal mechanisms. These considerations could also have implications for patients with obesity and the metabolic syndrome.
