Ulster Exclusion and Irish Nationalism: Consenting to the Principle of Partition, 1912-1916

In April 1912, Prime Minister Herbert Henry Asquith introduced the third Home Rule (Government of Ireland) Bill to Westminster. In so doing, he ignited a crisis in both Ireland and Britain which consumed political discourse right up to the eve of the First World War and beyond. By September of 1912, the Ulster question took centre stage as the dominant issue holding back the constitutionally predetermined progress of the Government of Ireland Bill.This article considers two important developments pertaining to Ulster within the broader Home Rule crisis. The first is the definition and rationalisation of a two-state solution to the so-called ‘Irish question’ which in 1914 resulted for the first time in the drafting of proposals for an Irish border, initially as a strictly temporary measure. The second theme here is to examine how, from November 1913 onwards, Nationalist politicians gradually and grudgingly came to accept, on a strictly temporary basis, the exclusion of a portion of the province of Ulster from the jurisdiction of a Home Rule parliament. This culminated in the summer of 1916 with a convention of nationalist delegates from the six Ulster counties earmarked for exclusion. At this conference, the leading Nationalist MP in Ulster, Joseph Devlin, prevailed upon his followers to vote themselves temporarily out of a Home Rule Ireland so as to ensure the immediate enactment of Home Rule for the rest of the island. Although the deal upon which this pact was predicated failed, it marked the moment where Ulster nationalists consented to the principle of partition. The partition of Ireland became a reality in 1921 and has remained the bedrock of the two-state solution to the Irish question ever since.En avril 1912, le Premier ministre Herbert Asquith introduisit le troisième projet de loi sur l’autonomie de l’Irlande (Government of Ireland Bill) au Parlement de Westminster. Ceci déclencha une crise qui influença le discours politique aussi bien en Irlande qu’en Grande-Bretagne et ce, jusqu’à la veille de la Première Guerre Mondiale et après. En septembre 1912, la question d’Ulster se trouva au centre des débats et devint l’obstacle prinicipal au progrès du projet de loi tel que défini par la constitution.Cet article examine deux éléments importants relatifs à l’Ulster dans le contexte plus large de la crise liée à la question du Home Rule. En premier lieu il s’agit de comprendre comment fut définie et rationalisée une solution à deux Etats à la question irlandaise, ce qui aboutit en 1914 à une ébauche des propositions de frontière irlandaise – solution qui, au départ, devait être strictement temporaire. Dans un second temps, il s’agira d’examiner comment, à partir de novembre 1913, les nationalistes en vinrent à accepter progressivement, à contre-coeur et sur une base strictement temporaire que soit exclue de la jurisdiction d’un parlement irlandais autonome une portion de la province d’Ulster.La crise culmina à l’été 1916 lors d’une convention réunissant des délégués nationalistes de six comtés d’Ulster et destinée à décider l’exclusion. Dans ce contexte, le chef de file des députés nationalistes d’Ulster Joseph Devlin, convainquit ses soutiens de voter l’exclusion temporaire de leurs comtés afin que la mise en place immédiate de l’autonomie législative pour le reste de l’Irlande puisse être assurée. Bien que l’arrangement sur lequel reposait ce pacte se fût soldé par un échec, ceci marqua le moment où les nationalistes d’Ulster acceptèrent le principe de la partition. Cette partition d’Irlande devint une réalité en 1921 et demeure le fondement de la solution en deux Etats à la question irlandaise

Vivienne Westwood and the ethics of consuming fashion

Our paper examines ethical consumption using the case study of Vivienne Westwood, the fashion designer, and her eponymous firm, and shows how consumers of fashion might be considered ethical. The fashion industry has figured prominently in ethical debates, notably its role in encouraging overconsumption of resources and promoting an idealised lifestyle that is often neither materially nor psychically sustainable for consumers (Buchholz, 1998). We acknowledge this, yet suggest the purchase and use of clothing carries with it the potential to be ethical insofar as customers find themselves personally implicated with and caring for a designers' work

Echocardiography in the flight program

Observations on American and Soviet astronauts have documented the association of changes in cardiovascular function during orthostasis with space flight. A basic understanding of the cardiovascular changes occurring in astronauts requires the determination of cardiac output and total peripheral vascular resistance as a minimum. In 1982, we selected ultrasound echocardiography as our means of acquiring this information. Ultrasound offers a quick, non-invasive and accurate means of determining stroke volume which, when combined with the blood pressure and heart rate measurements of the stand test, allows calculation of changes in peripheral vascular resistance, the body's major response to orthostatic stress. The history of echocardiography in the Space Shuttle Program is discussed and the results are briefly presented

Effects of oral semaglutide on cardiovascular outcomes in individuals with type 2 diabetes and established atherosclerotic cardiovascular disease and/or chronic kidney disease: Design and baseline characteristics of SOUL, a randomized trial

Aim: To describe the design of the SOUL trial (Semaglutide cardiOvascular oUtcomes triaL) and the baseline clinical data of its participants. Materials and methods: In SOUL, the effects of oral semaglutide, the first oral glucagon-like peptide-1 receptor agonist, on the risk of cardiovascular (CV) events in individuals with type 2 diabetes and established atherosclerotic CV disease (ASCVD) and/or chronic kidney disease (CKD) will be assessed. SOUL is a randomized, double-blind, parallel-group, placebo-controlled CV outcomes trial comparing oral semaglutide (14 mg once daily) with placebo, both in addition to standard of care, in individuals aged ≥50 years with type 2 diabetes and evidence of ASCVD (coronary artery disease [CAD], cerebrovascular disease, symptomatic peripheral arterial disease [PAD]) and/or CKD (estimated glomerular filtration rate <60 mL/min/1.73 m2). The primary outcome is time from randomization to first occurrence of a major adverse CV event (MACE; a composite of CV death, nonfatal myocardial infarction or nonfatal stroke). This event-driven trial will continue until 1225 first adjudication-confirmed MACEs have occurred. Enrolment has been completed. Results: Overall, 9650 participants were enrolled between June 17, 2019 and March 24, 2021 (men 71.1%, White ethnicity 68.9%, mean age 66.1 years, diabetes duration 15.4 years, body mass index 31.1 kg/m2, glycated haemoglobin 63.5 mmol/mol [8.0%]). The most frequently used antihyperglycaemic medications at baseline were metformin (75.7%), insulin and insulin analogues (50.5%), sulphonylureas (29.1%), sodium-glucose cotransporter-2 inhibitors (26.7%) and dipeptidyl peptidase-4 inhibitors (23.0%). At randomization, 70.7% of participants had CAD, 42.3% had CKD, 21.1% had cerebrovascular disease and 15.7% had symptomatic PAD (categories not mutually exclusive). Prevalent heart failure was reported in 23.0% of participants. Conclusion: SOUL will provide evidence regarding the CV effects of oral semaglutide in individuals with type 2 diabetes and established ASCVD and/or CKD

Alterations in Platelet Function and Cell-Derived Microvesicles in Recently Menopausal Women: Relationship to Metabolic Syndrome and Atherogenic Risk

A woman’s risk for metabolic syndrome (MS) increases at menopause, with an associated increase in risk for cardiovascular disease. We hypothesized that early menopause-related changes in platelet activity and concentrations of microvesicles derived from activated blood and vascular cells provide a mechanistic link to the early atherothrombotic process. Thus, platelet functions and cellular origin of blood-borne microvesicles in recently menopausal women (n = 118) enrolled in the Kronos Early Estrogen Prevention Study were correlated with components of MS and noninvasive measures of cardiovascular disease [carotid artery intima medial thickness (CIMT), coronary artery calcium (CAC) score, and endothelial reactive hyperemic index (RHI)]. Specific to individual components of the MS pentad, platelet number increased with increasing waist circumference, and platelet secretion of ATP and expression of P-selectin decreased with increasing blood glucose (p = 0.005) and blood pressure (p < 0.05), respectively. Waist circumference and systolic blood pressure were independently associated with monocyte- and endothelium-derived microvesicles (p < 0.05). Platelet-derived and total procoagulant phosphatidylserine-positive microvesicles, and systolic blood pressure correlated with CIMT (p < 0.05), but not with CAC or RHI. In summary, among recently menopausal women, specific platelet functions and concentrations of circulating activated cell membrane-derived procoagulant microvesicles change with individual components of MS. These cellular changes may explain in part how menopause contributes to MS and, eventually, to cardiovascular disease

The Canadian Women's Heart Health Alliance Atlas on the epidemiology, diagnosis, and management of cardiovascular disease in women - Chapter 5 : sex- and gender-unique manifestations of cardiovascular disease.

This Atlas chapter summarizes sex- and some gender-associated, and unique aspects and manifestations of cardiovascular disease (CVD) in women. CVD is the primary cause of premature death in women in Canada and numerous sex-specific differences related to symptoms and pathophysiology exist. A review of the literature was done to identify sex-specific differences in symptoms, pathophysiology, and unique manifestations of CVD in women. Although women with ischemic heart disease might present with chest pain, the description of symptoms, delay between symptom onset and seeking medical attention, and prodromal symptoms are often different in women, compared with men. Nonatherosclerotic causes of angina and myocardial infarction, such as spontaneous coronary artery dissection are predominantly identified in women. Obstructive and nonobstructive coronary artery disease, aortic aneurysmal disease, and peripheral artery disease have worse outcomes in women compared with men. Sex differences exist in valvular heart disease and cardiomyopathies. Heart failure with preserved ejection fraction is more often diagnosed in women, who experience better survival after a heart failure diagnosis. Stroke might occur across the lifespan in women, who are at higher risk of stroke-related disability and age-specific mortality. Sex- and gender-unique differences exist in symptoms and pathophysiology of CVD in women. These differences must be considered when evaluating CVD manifestations, because they affect management and prognosis of cardiovascular conditions in women.Dans le présent chapitre d’Atlas sont récapitulés les aspects et les manifestations uniques, associés au sexe et certains associés au genre, des maladies cardiovasculaires (MCV) chez les femmes. Les MCV sont la cause principale de décès prématurés chez les femmes au Canada. De nombreuses différences quant aux symptômes et à la physiopathologie existent entre les sexes. Nous avons réalisé une revue de la littérature pour déterminer les différences entre les sexes dans les symptômes et la physiopathologie, et les manifestations uniques des MCV chez les femmes. Bien que les femmes atteintes d’une cardiopathie ischémique puissent éprouver des douleurs thoraciques, la description des symptômes, le délai entre l’apparition des symptômes et l’obtention de soins médicaux, et les symptômes prodromiques sont souvent différents de ceux des hommes. Les causes de l’angine et de l’infarctus du myocarde non liées à l’athérosclérose telles que la dissection spontanée de l’artère coronaire sont principalement observées chez les femmes. La coronaropathie obstructive et non obstructive, l’anévrisme aortique et la maladie artérielle périphérique montrent de plus mauvaises issues chez les femmes que chez les hommes. Des différences entre les sexes sont observées dans la cardiopathie valvulaire et les cardiomyopathies. Le diagnostic d’insuffisance cardiaque avec fraction d’éjection préservée est plus souvent posé chez les femmes qui présentent un meilleur taux de survie après un diagnostic d’insuffisance cardiaque. L’accident vasculaire cérébral (AVC) pourrait survenir tout au long de la vie des femmes, qui sont exposées à un risque plus élevé d’incapacités liées à l’AVC et de mortalité par âge. Il existe des différences uniques entre les sexes et les genres pour ce qui est des symptômes et de la physiopathologie des MCV chez les femmes. Lors de l’évaluation des manifestations des MCV, il faut tenir compte de ces différences puisqu’elles influencent la prise en charge et le pronostic des maladies cardiovasculaires chez les femmes

Pretest Score for Predicting Microbubble Contrast Agent Use in Stress Echocardiography: A Method to Increase Efficiency in the Echo Laboratory

Background. In stress echocardiography, contrast agents are used selectively to improve endocardial border definition. Early identification of candidates may facilitate use of these agents in small and medium volume laboratories where resources are limited. Methods. We studied 15232 patients who underwent stress echocardiography. Contrast agent was used if 2 or more ventricular segments were not adequately visualized without contrast. Logistic regression models were used to evaluate the association between individual characteristics and contrast use. An 11-point score was derived from the significant characteristics. Results. Variables associated with microbubble use were age, sex, smoking, presence of multiple risk factors, bodymass index (BMI), referral for dobutamine stress echocardiography, history of coronary artery disease, and abnormal baseline electrocardiogram. All variables except BMI were given a score of 1 if present and 0 if absent; BMI was given a score of 0 to 4 according to its value. An increased score was directly proportional to increased likelihood of contrast use. The score cutoff value to optimize sensitivity and specificity was 5. Conclusions. A pretest score can be computed from information available before imaging. It may facilitate contrast agent use through early identification of patients who are likely to benefit from improved endocardial border definition

The Canadian Women's Heart Health Alliance atlas on the epidemiology, diagnosis, and management of cardiovascular disease in women - Chapter 6 : sex- and gender-specific diagnosis and treatment

This chapter summarizes the sex- and gender-specific diagnosis and treatment of acute/unstable presentations and nacute/stable presentations of cardiovascular disease in women. Guidelines, scientific statements, systematic reviews/meta-analyses, and primary research studies related to diagnosis and treatment of coronary artery disease, cerebrovascular disease (stroke), valvular heart disease, and heart failure in women were reviewed. The evidence is summarized as a narrative, and when available, sex- and gender-specific practice and research recommendations are provided. Acute coronary syndrome presentations and emergency department delays are different in women than they are in men. Coronary angiography remains the gold-standard test for diagnosis of obstructive coronary artery disease. Other diagnostic imaging modalities for ischemic heart disease detection (eg, positron emission tomography, echocardiography, single-photon emission computed tomography, cardiovascular magnetic resonance, coronary computed tomography angiography) have been shown to be useful in women, with their selection dependent upon both the goal of the individualized assessment and the testing resources available. Noncontrast computed tomography and computed tomography angiography are used to diagnose stroke in women. Although sex-specific differences appear to exist in the efficacy of standard treatments for diverse presentations of acute coronary syndrome, many cardiovascular drugs and interventions tested in clinical trials were not powered to detect sex-specific differences, and knowledge gaps remain. Similarly, although knowledge is evolving about sex-specific difference in the management of valvular heart disease, and heart failure with both reduced and preserved ejection fraction, current guidelines are lacking in sex-specific recommendations, and more research is needed.Ce chapitre présente un résumé sur le diagnostic et le traitement des tableaux cliniques aigus/instables et non aigus/stables des maladies cardiovasculaires chez les femmes, et les différences propres à chacun des deux sexes. Les lignes directrices, les énoncés scientifiques, les revues systématiques/méta-analyses et les études de recherche originale sur le diagnostic et le traitement des coronaropathies, des maladies vasculaires cérébrales (AVC), des valvulopathies cardiaques et de l’insuffisance cardiaque chez les femmes ont été examinés. Les données probantes sont résumées sous forme narrative et, lorsqu’elles sont disponibles, des recommandations en matière de pratique et de recherche pour chacun des deux sexes sont présentées. Les tableaux cliniques du syndrome coronarien aigu et les délais d’attente à l’urgence sont différents selon qu’une femme ou un homme en est atteint. L’angiographie coronarienne reste l’examen de référence pour le diagnostic des coronaropathies obstructives. D’autres examens d’imagerie diagnostique (p. ex. la tomographie par émission de positons, l’échocardiographie, la tomographie d'émission à photon unique, la résonance magnétique cardiovasculaire, l’angiographie coronarienne par tomodensitométrie) se sont avérés utiles pour la détection des cardiopathies ischémiques chez les femmes. Le recours à ces modalités dépend de l’objectif de l’évaluation personnalisée et des ressources disponibles. La tomodensitométrie sans agent de contraste et l’angiographie par tomodensitométrie sont utilisées pour le diagnostic des AVC chez les femmes. Malgré les différences entre les sexes quant à l’efficacité des traitements de référence des divers tableaux cliniques du syndrome coronarien aigu, bon nombre des médicaments et des interventions cardiovasculaires qui ont fait l’objet d’essais cliniques n’avaient pas la puissance statistique nécessaire pour détecter des différences selon les sexes, de sorte que les connaissances restent fragmentaires sur ce sujet. De même, malgré l’évolution des connaissances sur les différences sexuelles quant à la prise en charge des valvulopathies cardiaques et de l’insuffisance cardiaque avec fraction d’éjection réduite ou préservée, on ne trouve pas de recommandations pour chaque sexe dans les lignes directrices actuelles, d’où la pertinence d’études supplémentaires portant sur cette question

Left ventricular free wall impeding rupture in post-myocardial infarction period diagnosed by myocardial contrast echocardiography: Case report

BACKGROUND: Left ventricular free wall rupture occurs in up to 10% of the in-hospital deaths following myocardial infarction. It is mainly associated with posterolateral myocardial infarction and its antemortem diagnosis is rarely made. Contrast echocardiography has been increasingly used for the evaluation of myocardial perfusion in patients with acute myocardial infarction, with important prognostic implications. In this case, we reported its use for the detection of a mechanical complication following myocardial infarction. CASE PRESENTATION: A 50-year-old man with acute myocardial infarction in the lateral wall underwent myocardial contrast echocardiography for the evaluation of myocardial perfusion in the third day post-infarction. A perfusion defect was detected in lateral and inferior walls as well as the presence of contrast extrusion from the left ventricular cavity into the myocardium, forming a serpiginous duct extending from the endocardium to the epicardial region of the lateral wall, without communication with the pericardial space. Magnetic resonance imaging confirmed the diagnosis of impending rupture of the left ventricular free wall. While waiting for cardiac surgery, patient presented with cardiogenic shock and died. Anatomopathological findings were consistent with acute myocardial infarction in the lateral wall and a left ventricular free wall rupture at the infarct site. CONCLUSION: This case illustrates the early diagnosis of left ventricular free wall rupture by contrast echocardiography. Due to its ability to be performed at bedside this modality of imaging has the potential to identify this catastrophic condition in patients with acute myocardial infarction and help to treat these patients with emergent surgery
