Self-Reported Body Awareness: Validation of the Postural Awareness Scale and the Multidimensional Assessment of Interoceptive Awareness (Version 2) in a Non-clinical Adult French-Speaking Sample
Body awareness refers to the individual ability to process signals originating from within the body, which provide a mapping of the bodyâs internal landscape (interoception) and its relation with space and movement (proprioception). The present study aims to evaluate psychometric properties and validate in French two self-report measures of body awareness: the Postural Awareness Scale (PAS), and the last version of the Multidimensional Assessment of Interoceptive Awareness questionnaire (version 2, MAIA-2). We collected data in a non-clinical, adult sample (Nâ=â308; 61% women, mean age 35â±â12âyears) using online survey, and a subset of the original sample (nâ=â122; 62% women, mean age 44â±â11âyears) also completed the retest control. Factor analyses and reliability analyses were conducted. Construct validity of the PAS and the MAIA-2 were examined by testing their association with each other, and with self-report measures of personality (Big Five Inventory), alexithymia (Toronto Alexithymia Scale) and dispositional trait mindfulness (Freiburg Mindfulness Inventory). Factor analyses of the PAS supported the same two-factor structure as previously published versions (in other languages). For the MAIA-2, factor analyses suggested that a six-factor structure, excluding Not-Worrying and Not-Distracting factors, could successfully account for a common general factor of self-reported interoception. We found satisfactory internal consistency, construct validity, and reliability over time for both the PAS and the MAIA-2. Altogether, our findings suggest that the French version of the PAS and the MAIA-2 are reliable self-report tools to assess both components of body awareness (proprioception and interoception dimension, respectively)
The organic food philosophy. A qualitative exploration of the practices, values, and beliefs of Dutch organic consumers within a cultural-historical frame
Food consumption has been identified as a realm of key importance for progressing the world towards more sustainable consumption overall. Consumers have the option to choose organic food as a visible product of more ecologically integrated farming methods and, in general, more carefully produced food. This study aims to investigate the choice for organic from a cultural-historical perspective and aims to reveal the food philosophy of current organic consumers in The Netherlands. A concise history of the organic food movement is provided going back to the German Lebensreform and the American Natural Foods Movement. We discuss themes such as the wish to return to a more natural lifestyle, distancing from materialistic lifestyles, and reverting to a more meaningful moral life. Based on a number of in-depth interviews, the study illustrates that these themes are still of influence among current organic consumers who additionally raised the importance of connectedness to nature, awareness, and purity. We argue that their values are shared by a much larger part of Dutch society than those currently shopping for organic food. Strengthening these cultural values in the context of more sustainable food choices may help to expand the amount of organic consumers and hereby aid a transition towards more sustainable consumption. © 2012 The Author(s)

Osteoporosis and risk of fracture in heart transplant patients
IntroductionSignificant bone loss occurs after heart transplantation, predominantly in the first year, with increased risk of incident fractures. The goal of this study was to evaluate the prevalence of fragility fractures in a population of heart transplantation patients and to identify the independent risk factors for fractures.MethodsThis was a prospective monocentric study that included patients with heart transplantation occurring < 10 years who were undergoing heart transplantation monitoring. All patients underwent bone mineral density evaluation by dual-energy X-ray absorptiometry and radiographies to establish the presence of vertebral fractures.ResultsWe included 79 patients (61 men); the mean age was 56.8 ± 10.8 years. The mean time between transplantation and inclusion was 32.3 ± 35.0 months. Incident fractures were diagnosed in 21 (27%) patients after heart transplantation. Vertebral fractures were the most frequent (30 vertebral fractures for 15 patients). Osteoporosis was confirmed in 22 (28%) patients. Mean bone mineral density at the femoral neck and total hip was lower with than without fracture (femoral neck: 0.777 ± 0.125 vs 0.892 ± 0.174 g/cm2, p<0.01; total hip: 0.892 ± 0.165 vs 0.748 ± 0.07 g/cm2, p<0.001), with a significant result on multivariate analysis. The mean time from transplantation to the first fracture was 8.0 ± 7.6 months.DiscussionOur study confirmed a high vertebral fracture risk in heart transplant patients, especially during the first year after transplantation
Elucidating tricuspid Doppler signal interpolation and its implication for assessing pulmonary hypertension
Doppler echocardiography plays a central role in the assessment of pulmonary hypertension (PAH). We aim to improve quality assessment of systolic pulmonary arterial pressure (SPAP) by applying a cubic polynomial interpolation to digitized tricuspid regurgitation (TR) waveforms. Patients with PAH and advanced lung disease were divided into three cohorts: a derivation cohort (nâ=â44), a validation cohort (nâ=â71), an outlier cohort (nâ=â26), and a non-PAH cohort (nâ=â44). We digitized TR waveforms and analyzed normalized duration, skewness, kurtosis, and first and second derivatives of pressure. Cubic polynomial interpolation was applied to three physiology-driven phases: the isovolumic phase, ejection phase, and âshoulderâ point phase. Coefficients of determination and a BlandâAltman analysis was used to assess bias between methods. The cubic polynomial interpolation of the TR waveform correlated strongly with expert read right ventricular systolic pressure (RVSP) with R2 >â0.910 in the validation cohort. The biases when compared to invasive SPAP measured within 24âh were 6.03 [4.33; 7.73], â2.94 [1.47; 4.41], and â3.11 [â4.52; â1.71]âmmHg, for isovolumic, ejection, and shoulder point interpolations, respectively. In the outlier cohort with more than 30% difference between echocardiographic estimates and invasive SPAP, cubic polynomial interpolation significantly reduced underestimation of RVSP. Cubic polynomial interpolation of the TR waveform based on isovolumic or early ejection phase may improve RVSP estimates.QC 20230607</p
Metagenomic Analysis of Microdissected Valvular Tissue for Etiologic Diagnosis of Blood Culture Negative Endocarditis
International audienceBackgroundEtiological diagnosis is a key to therapeutic adaptation and improved prognosis, particularly for infections such as endocarditis. In blood cultureânegative endocarditis (BCNE), 22% of cases remain undiagnosed despite an updated comprehensive syndromic approach. This prompted us to develop a new diagnostic approach.MethodsEleven valves from 10 BCNE patients were analyzed using a method that combines human RNA bait-depletion with phi29 DNA polymerase-based multiple displacement amplification and shotgun DNA sequencing. An additional case in which a microbe was serendipitously visualized by immunofluorescence was analyzed using the same method, but after laser capture microdissection.ResultsBackground DNA prevented any diagnosis in cases analyzed without microdissection because the majority of sequences were contaminants. Moraxella sequences were dramatically enriched in the stained microdissected region of the additional case. A consensus genome sequence of 2.4 Mbp covering more than 94% of the Moraxella osloensis KSH reference genome was reconstructed with 234X average coverage. Several antibiotic-resistance genes were observed. Etiological diagnosis was confirmed using Western blot and specific polymerase chain reaction with sequencing on a different valve sample.ConclusionsMicrodissection could be a key to the metagenomic diagnosis of infectious diseases when a microbe is visualized but remains unidentified despite an updated optimal approach. Moraxella osloensis should be tested in blood cultureânegative endocarditi
Acute Pulmonary Edema After Double Mechanical Valve Replacement
We report a case of a 16-year-old man in cardiogenic shock secondary to On-X mitral prosthesis dysfunction due to leaflet embolization through aortic mechanical prosthesis. He underwent an emergency redo mitral valve replacement and, a few days later, leaflet removal by open aortic surgery with full recovery
