The class differentiation of older age: Capitals and lifestyles.

Older people have been overlooked in recent debates over the relationship between age, class and culture despite their prevalence and the conceptual questions they raise. Seeking to bridge mainstream class analysis with debates in social gerontology, especially via a shared turn to Pierre Bourdieu's relational sociology, this paper draws on survey data from the US to examine not only the class position of older people but their internal social and cultural differentiation. I use geometric data analysis to construct a model of the class system, locate older people within it and then explore differences among older people.

Rethinking the nation and international relations: The space of nation states.

Efforts to move sociology beyond the nation state and international relations theory have both been plagued by several limitations and dualisms. Recent research has begun to find ways beyond the problems by turning to Pierre Bourdieu's relational conception of social structure and practice. Yet one specific relational structure forming a key part of the puzzle has been neglected or merely implicitly assumed so far: the space of nation states.

Impact of Medical Student Participation in Student-Run Clinics on Education, Residency Selection, and Patient Care: A Review of Selected Articles.

Student-run clinics (SRCs) are becoming increasingly popular at medical schools in the United States. These clinics have provided a variety of benefits, including serving disadvantaged populations and providing early clinical exposure for students. There has been no consensus on the impact of SRCs on medical education, specialty selection, and patient care.

The genesis of Brexit in the UK: outline of a multi-field model.

This paper outlines a sociological model of the conditions of possibility of the UK's decision to withdraw from the European Union in 2016. Drawing on the conceptual tools of Pierre Bourdieu and those inspired by him, it synthesises and goes beyond the partial and fragmentary accounts offered so far to offer a more comprehensive narrative implicating the interrelation of multiple fields, with agents' evolving strategies within the different fields being the major fulcra. To be specific, the conditions of possibility for the referendum result were provided by mutations within the global field of nation states ricocheting through the UK's political field, ethno-racial field and class structure.

The structure of food taste in 21 century Britain.

This paper draws on the concepts and tools of Pierre Bourdieu to construct a comprehensive model of the contemporary British "food space." It uses multiple correspondence analysis to unearth a space structured in two key dimensions revolving around the lean and the rich. A host of supplementary variables are available to examine the relationship, or homology, between food tastes and broader alimentary dispositions, including orientations toward shopping, ethics and cooking.

Testing an early online intervention for the treatment of disturbed sleep during the COVID-19 pandemic (Sleep COVID-19): structured summary of a study protocol for a randomised controlled trial.

Objectives: The primary aim of the present study is to examine the efficacy of an online intervention for poor sleep in the context of an ongoing stressful major life event, by assessing if this intervention can reduce insomnia severity at short-term (one week post-intervention) and long-term (one and three months post-intervention) follow-up time points. It is hypothesised that the intervention will: 1) reduce insomnia severity in poor sleepers, compared to wait-list control poor sleepers, and good sleepers; 2) reduce subjective symptoms of anxiety and depression in all groups, and 3) prevent the transition to acute insomnia in good sleepers.

Trial Design: This study is a cluster randomised controlled trial.

Modified transverse Ising model for the dielectric properties of SrTiO films and interfaces.

The transverse Ising model (TIM), with pseudospins representing the lattice polarization, is often used as a simple description of ferroelectric materials. However, we demonstrate that the TIM, as it is usually formulated, provides an incorrect description of SrTiO films and interfaces because of its inadequate treatment of spatial inhomogeneity. We correct this deficiency by adding a pseudospin anisotropy to the model.

Risk of Lung Cancer Mortality in Nuclear Workers from Internal Exposure to Alpha Particle-emitting Radionuclides.

Background: Carcinogenic risks of internal exposures to alpha-emitters (except radon) are poorly understood. Since exposure to alpha particles-particularly through inhalation-occurs in a range of settings, understanding consequent risks is a public health priority. We aimed to quantify dose-response relationships between lung dose from alpha-emitters and lung cancer in nuclear workers.

Hybrid FDG-PET/MR compared to FDG-PET/CT in adult lymphoma patients.

Purpose: The goal of this study is to evaluate the diagnostic performance of simultaneous FDG-PET/MR including diffusion compared to FDG-PET/CT in patients with lymphoma.

Methods: Eighteen patients with a confirmed diagnosis of non-Hodgkin's (NHL) or Hodgkin's lymphoma (HL) underwent an IRB-approved, single-injection/dual-imaging protocol consisting of a clinical FDG-PET/CT and subsequent FDG-PET/MR scan. PET images from both modalities were reconstructed iteratively.

Concerted Uranium Research in Europe (CURE): toward a collaborative project integrating dosimetry, epidemiology and radiobiology to study the effects of occupational uranium exposure.

The potential health impacts of chronic exposures to uranium, as they occur in occupational settings, are not well characterized. Most epidemiological studies have been limited by small sample sizes, and a lack of harmonization of methods used to quantify radiation doses resulting from uranium exposure. Experimental studies have shown that uranium has biological effects, but their implications for human health are not clear.

Myeloperoxidase Nuclear Imaging for Epileptogenesis.

Purpose: To determine if myeloperoxidase (MPO) is involved in epileptogenesis and if molecular nuclear imaging can be used to noninvasively map inflammatory changes in epileptogenesis.

Materials And Methods: The animal and human studies were approved by the institutional review boards. Pilocarpine-induced epileptic mice were treated with 4-aminobenzoic acid hydrazide (n = 46), a specific irreversible MPO inhibitor, or saline (n = 42).

Betaine and Trimethylamine-N-Oxide as Predictors of Cardiovascular Outcomes Show Different Patterns in Diabetes Mellitus: An Observational Study.

Background: Betaine is a major osmolyte, also important in methyl group metabolism. Concentrations of betaine, its metabolite dimethylglycine and analog trimethylamine-N-oxide (TMAO) in blood are cardiovascular risk markers. Diabetes disturbs betaine: does diabetes alter associations between betaine-related measures and cardiovascular risk?

Methods: Plasma samples were collected from 475 subjects four months after discharge following an acute coronary admission.

Emergency department CT screening of patients with nontraumatic neurological symptoms referred to the posterior fossa: comparison of thin versus thick slice images.

Evaluation of the posterior fossa (PF) on 5-mm-thick helical CT images (current default) has improved diagnostic accuracy compared to 5-mm sequential CT images; however, 5-mm-thick images may not be ideal for PF pathology due to volume averaging of rapid changes in anatomy in the Z-direction. Therefore, we sought to determine if routine review of 1.25-mm-thin helical CT images has superior accuracy in screening for nontraumatic PF pathology.

Class habitus and perception of the future: recession, employment insecurity and temporality.

This paper examines the consequences of the recent economic downturn and UK government spending cuts, as exacerbations of prevailing trends in neoliberal employment policy, on temporal perception, specifically as it relates to the adaptation of subjective anticipations of and projections into the future to objective prospects of unemployment by class. Grounded in a phenomenologically-minded Bourdieusian conceptualization of class and time and contextualized by statistics on chances of job loss, it draws on qualitative research with 57 individuals from across the class structure to chart differing dispositions toward the future. In particular, it distinguishes three orientations - the future as controllable, the future as uncontrollable and the future as reasonably controllable - which appear to correspond with resources possessed.

Vasa vasorum enhancement on computerized tomographic angiography correlates with symptomatic patients with 50% to 70% carotid artery stenosis.

Background And Purpose: Significant stenosis of the internal carotid artery (ICA) is an established stroke risk factor. Recent evidence suggests that features within the atherosclerotic plaque also have prognostic value. The purpose of this study was to correlate the enhancement of the vasa vasorum (VV) overlying the carotid artery plaque with acute neurological symptoms in patients with 50% to 70% ICA stenosis.

Robust nodal d-wave spectrum in simulations of a strongly fluctuating competing order in underdoped cuprate superconductors.

We resolve an existing discrepancy between convincing evidence for competing order in underdoped cuprates and spectroscopic data consistent with a homogeneous d-wave superconductor in the very same compounds. Specifically, we show that fluctuations of the competing order generate strongly inhomogeneous states whose spectra are almost indistinguishable from the pure d-wave superconductor. This is in contrast to the commonly studied case of homogeneously coexisting order, which typically generates a reconstructed Fermi surface with closed Fermi pockets.

Betaine and secondary events in an acute coronary syndrome cohort.

Background: Betaine insufficiency is associated with unfavourable vascular risk profiles in metabolic syndrome patients. We investigated associations between betaine insufficiency and secondary events in acute coronary syndrome patients.

Methods: Plasma (531) and urine (415) samples were collected four months after discharge following an acute coronary event.

Ligation of the jugular veins does not result in brain inflammation or demyelination in mice.

An alternative hypothesis has been proposed implicating chronic cerebrospinal venous insufficiency (CCSVI) as a potential cause of multiple sclerosis (MS). We aimed to evaluate the validity of this hypothesis in a controlled animal model. Animal experiments were approved by the institutional animal care committee.

Demyelinating diseases: myeloperoxidase as an imaging biomarker and therapeutic target.

Purpose: To evaluate myeloperoxidase (MPO) as a newer therapeutic target and bis-5-hydroxytryptamide-diethylenetriaminepentaacetate-gadolinium (Gd) (MPO-Gd) as an imaging biomarker for demyelinating diseases such as multiple sclerosis (MS) by using experimental autoimmune encephalomyelitis (EAE), a murine model of MS.

Materials And Methods: Animal experiments were approved by the institutional animal care committee. EAE was induced in SJL mice by using proteolipid protein (PLP), and mice were treated with either 4-aminobenzoic acid hydrazide (ABAH), 40 mg/kg injected intraperitoneally, an irreversible inhibitor of MPO, or saline as control, and followed up to day 40 after induction.

The contrasting relationships between betaine and homocysteine in two clinical cohorts are associated with plasma lipids and drug treatments.

Background: Urinary betaine excretion positively correlated with plasma homocysteine in outpatients attending a lipid disorders clinic (lipid clinic study). We aimed to confirm this in subjects with established vascular disease.

Methods: The correlation between betaine excretion and homocysteine was compared in samples collected from subjects 4 months after hospitalization for an acute coronary episode (ACS study, 415 urine samples) and from 158 sequential patients visiting a lipid disorders clinic.

Plasma lipids and betaine are related in an acute coronary syndrome cohort.

Background: Low plasma betaine has been associated with unfavorable plasma lipid profiles and cardiovascular risk. In some studies raised plasma betaine after supplementation is associated with elevations in plasma lipids. We aimed to measure the relationships between plasma and urine betaine and plasma lipids, and the effects of lipid-lowering drugs on these.
