The Psycho-Affective Echoes of Colonialism in Fieldwork Relations

This article describes the varieties of relations with African immigrant interviewees in Tuscany as experienced by a white male interviewer from the United States. Franz FANON\u27s discussion of the psycho-affective consequences of colonialism is vital for understanding how naïve and romantic notions of fieldwork relations are disingenuous, counter-productive and perhaps destructive in a neo-colonial landscape

Primary Percutaneous Coronary Intervention in Patients With Acute Myocardial Infarction, Resuscitated Cardiac Arrest, and Cardiogenic Shock The Role of Primary Multivessel Revascularization

ObjectivesThis study sought to assess the impact of multivessel (MV) primary percutaneous coronary intervention (PCI) on clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) presenting with cardiogenic shock (CS) and resuscitated cardiac arrest (CA).BackgroundThe safety and efficacy of MV primary PCI in patients with STEMI and refractory CS is unknown.MethodsWe conducted a multicenter prospective observational study of consecutive STEMI patients presenting to 5 French centers. Patients were classified as having single-vessel (SVD) or multivessel (MVD) coronary disease, and underwent culprit-only or MV primary PCI. Baseline characteristics and 6-month survival were compared.ResultsAmong 11,530 STEMI patients, 266 had resuscitated CA and CS. Patients with SVD (36.5%) had increased 6-month survival compared to those with MVD (29.6% vs. 42.3%, p = 0.032). Baseline characteristics were similar in those with MVD undergoing culprit-only (60.9%) or MV (39.1%) primary PCI. However, 6-month survival was significantly greater in patients who underwent MV PCI (43.9% vs. 20.4%, p = 0.0017). This survival advantage was mediated by a reduction in the composite of recurrent CA and death due to shock (p = 0.024) in MV PCI patients. In those with MVD, culprit artery PCI success (hazard ratio [HR]: 0.63; 95% confidence interval [CI]: 0.41 to 0.96, p = 0.030) and MV primary PCI (HR: 0.57; 95% CI: 0.38 to 0.84, p = 0.005) were associated with increased 6-month survival.ConclusionsThe results of this study suggest that in STEMI patients with MVD presenting with CS and CA, MV primary PCI may improve clinical outcome. Randomized trials are required to verify these results

Analytical evidence of enamel hypomineralisation on permanent and primary molars amongst past populations /631/181/19/2471 /692/699 /123 article

Molar Incisor Hypomineralisation (MIH) and Hypomineralised Second Primary Molars (HSPM) involve prevalent qualitative structural developmental anomalies of tooth enamel affecting the first permanent molars (and often incisors) and the second primary molars, respectively. These demarcated hypomineralised lesions of enamel manifest as white-cream or yellow-brown opacities, with possible post-eruptive localised loss of enamel. Aetiological hypotheses have involved contemporary life factors (i.e. environmental pollutant exposure or early childhood medications) in contrast to factors not limited to a specific time period (i.e. hypoxia at birth or genetic predisposition). Evidence of MIH in ancient populations would reinforce aetiological factors present for many centuries. By means of microtomographic and X-ray fluorescence analyses the present study provides evidence that (i) two archaeological specimens: "S407" (Sains-en-Gohelle, France, 12th-16th centuries) and "B335" (Beauvais, France, 15th-18th centuries) were MIH-affected, and (ii) one individual "S323" was affected by HSPM and MIH (Sains-en-Gohelle, France, 7th-11th centuries)

Mineral density of hypomineralised and sound enamel

Molar Incisor Hypomineralisation (MIH) is a structural anomaly that affects the quality of tooth enamel and has important consequences for oral health. The developmentally hypomineralised enamel has normal thickness and can range in colour from white to yellow or brown. The purpose of the present study is to compare the mineral density of hypomineralised and normal enamel. The sample included eight MIH teeth from seven patients. MIH teeth were scanned using high resolution microtomography. Non-parametric statistical tests (Wilcoxon test for paired samples) were carried out. Hypomineralised enamel has decreased mineral density (mean 19%; p < 0.0001) compared to normal enamel. This weak enamel has implications in clinical management of MIH lesions

Stratification of single-vessel coronary stenosis by ischemic threshold at the onset of wall motion abnormality during continuous monitoring of left ventricular function by semisupine exercise echocardiography.

peer reviewedWe studied the relation between the ischemic threshold at the onset of wall motion abnormality on exercise echocardiography (EE) and the severity of coronary stenosis in patients with 1-vessel coronary artery disease (CAD). We screened 216 consecutive patients who underwent coronary angiography and EE for suspected CAD. Ninety-five (74 men; age, 56 +/- 12 years) satisfied the study criteria, that is, the presence of 1-vessel disease or no evidence of CAD on angiography and a normal baseline echocardiogram. Eighty-seven patients had 1-vessel CAD on angiography, and exercise-induced wall motion abnormality occurred in 73 (77%). Optimal cutoff values of percent diameter stenosis and minimal lumen diameter for predicting a positive EE were 61% (sensitivity and specificity of 76%) and 1.12 mm (sensitivity and specificity of 74%). Among patients with positive EE, heart rate-blood pressure product at ischemic threshold was correlated with quantitative coronary stenosis (r = -0.72, P <.001). The ischemic threshold from continuous monitoring of left ventricular function during semisupine EE is correlated with the severity of coronary stenosis among patients with 1-vessel disease and a normal resting echocardiogram

Device-Related Thrombus After Left Atrial Appendage Closure

Although left atrial appendage closure (LAAC) has proved non-inferior to oral anticoagulants in patients with AF, there has been recent concern about the occurrence of late complications, especially device-related thrombus (DRT), which was associated with increased risk of stroke. In this article, the incidence, risk factors and time course of DRT after LAAC are discussed, as well as the potential benefits of dedicated strategies in the management of DRT, which remain speculative, especially in patients with a contraindication to oral anticoagulants. In these patients, decision-making should be based on a multidisciplinary evaluation of the ischaemic/bleeding balance on an individual basis
