Extending the consumer style inventory to define consumer typologies for secondhand clothing consumption in Poland

Purpose: This paper tests the generalizability and veracity of an extended version of the original consumer styles inventory (CSI) framework for an under examined context, secondhand clothing consumption in Poland. Design/Methodology/Approach: From the extant literature on retail fashion consumption in Poland, the CSI framework is newly extended to include four additional ‘styles’ for secondhand clothing, with four respective hypotheses formulated to test. A total of 509 questionnaires were commissioned by the Brand Experience Research Agency in Poland in July 2016. The target sample comprised a mixed sample almost evenly distributed between female (52.7% - 268 responses) and male (47.3% - 241 responses) participants. A representative sample of consumers geographically, with a majority living in cities across Poland between 50.000 and 500.000 inhabitants, was accessed. Findings: The results confirm that the original CSI framework is partially accepted within the Polish market, with overall results supporting a modified version of the inventory. The reported results highlight that there are some distinct cultural differences when applying the Consumer Styles Inventory in Poland, an overall finding that is synonymous with other international CSI studies. It can be concluded that consumers in emerging markets are to some extent different to those in developed markets, due to a variety of social as well as cultural and economic factors. Practical Implications: For Polish consumers, the purchase of secondhand garments appears to be a reflection, to follow shortcuts to pursue Western European patterns, where clothing is a form of resistance to purchasing newly produced mainstream fashion. Originality/Value: This research newly extends the CSI framework to incorporate additional shopper styles for Polish consumers. Furthermore, this study contributes to the body of research within the CSI remit by adding results for an additional country, which has been examined rarely before.peer-reviewe

Partners of nulliparous women with severe fear of childbirth: a longitudinal 1 study of psychological well being

Background: Little is known about the psychological status of partners of women with severe fear of childbirth (FOC). In this longitudinal study from Helsinki University Central Hospital, we investigated FOC, depression and post- traumatic stress in the partners of women with severe FOC, and possible effects of group psychoeducation and mode of birth. Methods: During pregnancy, 250 partners of nulliparous women with severe FOC participated, 93 in the intervention group and 157 in the control group. At three months postpartum 52 partners in the intervention group and 93 in the control group participated. Both the partners and the childbearing women filled in the Wijma Delivery Expectancy Questionnaire and the Edinburgh Postnatal Depression Scale mid-pregnancy as well as three months postpartum, when they also filled in the Traumatic Event Scale. Results: Partners of women with severe FOC reported less antenatal and postnatal FOC and fewer depressive symptoms than the childbearing women. No partner reached the threshold of severe FOC. No partner reported a possible post-traumatic stress disorder. Group psychoeducation with relaxation was not associated with better or worse psychological well being of the partners. An emergency cesarean section 1 was associated with a more fearful delivery experience in the partners. Conclusion: Partners of nulliparous women with severe FOC neither seem to suffer from severe FOC nor reported post-traumatic stress symptoms after childbirth. They reported better psychological well being than the mothers both during pregnancy and after delivery. An unexpected cesarean may be a negative experience even for 6 partners of childbearing women

The use of 2-D speckle tracking echocardiography in assessing adolescent athletes with left ventricular hypertrabeculation meeting the criteria for left ventricular non-compaction cardiomyopathy

BACKGROUND: Current echocardiographic criteria cannot accurately differentiate exercise induced left ventricular (LV) hypertrabeculation in athletes from LV non-compaction cardiomyopathy (LVNC). This study aims to evaluate the role of speckle tracking echocardiography (STE) in characterising LV myocardial mechanics in healthy adolescent athletes with and without LVNC echocardiographic criteria. METHODS: Adolescent athletes evaluated at three sports academies between 2014 and 2019 were considered for this observational study. Those meeting the Jenni criteria for LVNC (end-systolic non-compacted/compacted myocardium ratio > 2 in any short axis segment) were considered LVNC+ and the rest LVNC-. Peak systolic LV longitudinal strain (Sl), circumferential strain (Sc), rotation (Rot), corresponding strain rates (SRl/c) and segmental values were calculated and compared using a non-inferiority approach. RESULTS: A total of 417 participants were included, mean age 14.5 ± 1.7 years, of which 6.5% were LVNC+ (n = 27). None of the athletes showed any additional LVNC clinical criteria. All average Sl, SRl Sc, SRc and Rot values were no worse in the LVNC+ group compared to LVNC- (p values range 0.0003-0.06), apart from apical SRc (p = 0.2). All 54 segmental measurements (Sl/Sc SRl/SRc and Rot) had numerically comparable means in both LVNC+ and LVNC-, of which 69% were also statistically non-inferior. CONCLUSIONS: Among healthy adolescent athletes, 6.5% met the echocardiographic criteria for LVNC, but showed normal LV STE parameters, in contrast to available data on paediatric LVNC describing abnormal myocardial function. STE could better characterise the myocardial mechanics of athletes with LV hypertrabeculation, thus allowing the transition from structural to functional LVNC diagnosis, especially in suspected physiological remodelling

RESEARCH DESIGN AND METHODS Cav1 knockout and wild-type C57BL/6 mice were rendered diabetic with streptozotocin, and changes in motor nerve conduction velocity (MNCV), mechanical and thermal hypoalgesia, Erb B2 phosphorylation (pErb B2), and epidermal nerve fiber density were assessed. The contribution of Erb B2 to DPN was assessed using the Erb B2 inhibitors PKI 166 and erlotinib and a conditional bitransgenic mouse that expressed a constitutively active form of Erb B2 in myelinated Schwann cells (SCs). RESULTS Diabetic mice exhibited decreased MNCV and mechanical and thermal sensitivity, but the extent of these deficits was more severe in diabetic Cav1 knockout mice. Diabetes increased pErb B2 levels in both genotypes, but the absence of Cav1 correlated with a greater increase in pErb B2. Erb B2 activation contributed to the mechanical hypoalgesia and MNCV deficits in both diabetic genotypes because treatment with erlotinib or PKI 166 improved these indexes of DPN. Similarly, induction of a constitutively active Erb B2 in myelinated SCs was sufficient to decrease MNCV and induce a mechanical hypoalgesia in the absence of diabetes. CONCLUSIONS Increased Erb B2 activity contributes to specific indexes of DPN, and Cav1 may be an endogenous regulator of Erb B2 signaling. Altered Erb B2 signaling is a novel mechanism that contributes to SC dysfunction in diabetes, and inhibiting Erb B2 may ameliorate deficits of tactile sensitivity in DPN. Diabetic peripheral neuropathy (DPN) is a common complication of diabetes (1). Although hyperglycemia is the definitive cause of DPN (2), the vascular, glial, and neuronal damage that underlies the progressive axonopathy in DPN has a complex biochemical etiology involving oxidative stress (3,4), protein glycation (5), protein kinase C activation (6), polyol synthesis (7), and the hexosamine pathway (8). Altered neurotrophic support also contributes to sensory neuron dysfunction in DPN (9), but whether diabetes may alter growth factor signaling in Schwann cells (SCs), which also undergo substantial degeneration in diabetes, is poorly defined. Neuregulins are growth factors that control SC growth, survival, and differentiation via their interaction with Erb B receptors (10). Although Erb B2 signaling promotes developmental myelination and is clearly trophic for SCs, pharmacological evidence supports that pathologic activation of Erb B2 after axotomy (11) or infection with leprosy bacilli (12) is sufficient to induce SC dedifferentiation and demyelination. Additionally, genetic evidence supports that Erb B2 can promote the development of sensory neuropathies independent of diabetes because expression of a dominant-negative Erb B4 in nonmyelinating (13) or myelinating (14) SCs induced a temperature or mechanical sensory neuropathy, respectively. Given the contribution of Erb B2 to the degeneration of SCs, endogenous proteins that regulate Erb B2 activity may influence the development of certain aspects of sensory neuropathies. The interaction of Erb B2 with the protein caveolin-1 (Cav1) inhibits the intrinsic tyrosine kinase activity of the receptor (15). Cav1 is highly expressed in mature, myelinated SCs (16), and we have shown that prolonged hyperglycemia promoted the downregulation of Cav1 in SCs of sciatic nerve (17). Cav1 may regulate Erb B2 signaling in SCs because its forced downregulation was sufficient to enhance neuregulin-induced demyelination of SC–dorsal root ganglion (DRG) neuron cocultures (18). However, it is unknown whether an increase in Erb B2 activity may contribute to the pathophysiological development of DPN and if changes in Cav1 expression may alter Erb B2 activation in diabetic nerve. In the current study, we demonstrate that diabetic Cav1 knockout mice showed an increased activation of Erb B2 and developed greater motor nerve conduction velocity (MNCV) deficits relative to their wild-type counterparts. Inhibition of Erb B2 with two structurally diverse inhibitors corrected the MNCV deficits and mechanical hypoalgesia evident after 6 or 15 weeks of diabetes. Also, induction of a constitutively active Erb B2 in myelinated SCs of adult mice was sufficient to recapitulate the MNCV and mechanical sensitivity deficits observed in the diabetic mice. These studies provide the first evidence that activation of Erb B2 contributes to deficits associated with myelinated fiber function in diabetic nerve and suggest that Cav1 may serve as an endogenous regulator of Erb B2.This work was supported by grants from the Juvenile Diabetes Research Foundation and the National Institutes of Health (NS-054847 and DK-073594)

The neural correlates of inner speech defined by voxel-based lesion–symptom mapping

The neural correlates of inner speech have been investigated previously using functional imaging. However, methodological and other limitations have so far precluded a clear description of the neural anatomy of inner speech and its relation to overt speech. Specifically, studies that examine only inner speech often fail to control for subjects’ behaviour in the scanner and therefore cannot determine the relation between inner and overt speech. Functional imaging studies comparing inner and overt speech have not produced replicable results and some have similar methodological caveats as studies looking only at inner speech. Lesion analysis can avoid the methodological pitfalls associated with using inner and overt speech in functional imaging studies, while at the same time providing important data about the neural correlates essential for the specific function. Despite its advantages, a study of the neural correlates of inner speech using lesion analysis has not been carried out before. In this study, 17 patients with chronic post-stroke aphasia performed inner speech tasks (rhyme and homophone judgements), and overt speech tasks (reading aloud). The relationship between brain structure and language ability was studied using voxel-based lesion–symptom mapping. This showed that inner speech abilities were affected by lesions to the left pars opercularis in the inferior frontal gyrus and to the white matter adjacent to the left supramarginal gyrus, over and above overt speech production and working memory. These results suggest that inner speech cannot be assumed to be simply overt speech without a motor component. It also suggests that the use of overt speech to understand inner speech and vice versa might result in misleading conclusions, both in imaging studies and clinical practice

The use of 2-D speckle tracking echocardiography in differentiating healthy adolescent athletes with right ventricular outflow tract dilation from patients with arrhythmogenic cardiomyopathy

AIMS: Echocardiographic assessment of adolescent athletes for arrhythmogenic cardiomyopathy (ACM) can be challenging owing to right ventricular (RV) exercise-related remodelling, particularly RV outflow tract (RVOT) dilation. The aim of this study is to evaluate the role of RV 2-D speckle tracking echocardiography (STE) in comparing healthy adolescent athletes with and without RVOT dilation to patients with ACM. METHODS AND RESULTS: A total of 391 adolescent athletes, mean age 14.5 ± 1.7 years, evaluated at three sports academies between 2014 and 2019 were included, and compared to previously reported ACM patients (n = 38 definite and n = 39 borderline). Peak systolic RV free wall (RVFW-Sl), global and segmental strain (Sl), and corresponding strain rates (SRl) were calculated. The participants meeting the major modified Task Force Criteria (mTFC) for RVOT dilation were defined as mTFC+ (n = 58, 14.8%), and the rest as mTFC- (n = 333, 85.2%). Mean RVFW-Sl was -27.6 ± 3.4% overall, -28.2 ± 4.1% in the mTFC+ group and - 27.5 ± 3.3% in the mTFC- group. mTFC+ athletes had normal RV-FW-Sl when compared to definite (-29% vs -19%, p < 0.001) and borderline ACM (-29% vs -21%, p < 0.001) cohorts. In addition, all mean global and regional Sl and SRl values were no worse in the mTFC+ group compared to the mTFC- (p values range < 0.0001 to 0.1, inferiority margin of 2% and 0.1 s-1 respectively). CONCLUSIONS: In athletes with RVOT dilation meeting the major mTFC, STE evaluation of the RV can demostrate normal function and differentiate physiological remodelling from pathological changes found in ACM, improving screening in grey-area cases

A cross dialectal view of the Arabic dative alternation

This paper is concerned with the syntax of ditransitive verbs in Arabic.We concentrate on the vernaculars, focussing in particular on three geographically spread dialects: Egyptian Cairene Arabic, the dominant vernacular in Egypt, Hijazi Arabic, spoken in Western Saudi Arabia and Maltese, a mixed language with a Magrebi/Siculo-Arabic stratum. We show that all three exhibit an alternation (the dative alternation) between a ditransitive ('double object') construction and a corresponding prepositional dative construction, and outline a number of differences between these constructions in the different varieties of Arabic. We consider the distribution of verbs exhibiting the dative alternation in the light of Ryding's (2011) observations concerning Modern Standard Arabic

Myocardial inflammation and energetics by cardiac MRI : a review of emerging techniques

The role of inflammation in cardiovascular pathophysiology has gained a lot of research interest in recent years. Cardiovascular Magnetic Resonance has been a powerful tool in the non-invasive assessment of inflammation in several conditions. More recently, Ultrasmall superparamagnetic particles of iron oxide have been successfully used to evaluate macrophage activity and subsequently inflammation on a cellular level. Current evidence from research studies provides encouraging data and confirms that this evolving method can potentially have a huge impact on clinical practice as it can be used in the diagnosis and management of very common conditions such as coronary artery disease, ischaemic and non-ischaemic cardiomyopathy, myocarditis and atherosclerosis. Another important emerging concept is that of myocardial energetics. With the use of phosphorus magnetic resonance spectroscopy, myocardial energetic compromise has been proved to be an important feature in the pathophysiological process of several conditions including diabetic cardiomyopathy, inherited cardiomyopathies, valvular heart disease and cardiac transplant rejection. This unique tool is therefore being utilized to assess metabolic alterations in a wide range of cardiovascular diseases. This review systematically examines these state-of-the-art methods in detail and provides an insight into the mechanisms of action and the clinical implications of their use
