Ultrasound-assessed non-culprit and culprit coronary vessels differ by age and gender

AIM To investigate age- and gender-related differences in non-culprit versus culprit coronary vessels assessed with virtual histology intravascular ultrasound (VH-IVUS). METHODS In 390 patients referred for coronary angiography to a single center (Luzerner Kantonsspital, Switzerland) between May 2007 and January 2011, 691 proximal vessel segments in left anterior descending, circumflex and/or right coronary arteries were imaged by VH-IVUS. Plaque burden and plaque composition (fibrous, fibro-fatty, necrotic core and dense calcium volumes) were analyzed in 3 age tertiles, according to gender and separated for vessels containing non-culprit or culprit lesions. To classify as vessel containing a culprit lesion, the patient had to present with an acute coronary syndrome, and the VH-IVUS had to be performed in a vessel segment containing the culprit lesion according to conventional coronary angiography. RESULTS In non-culprit vessels the plaque burden increased significantly with aging (in men from 37% ± 12% in the lowest to 46% ± 10% in the highest age tertile, P < 0.001; in women from 30% ± 9% to 40% ± 11%, P < 0.001); men had higher plaque burden than women at any age (P < 0.001 for each of the 3 age tertiles). In culprit vessels of the lowest age tertile, plaque burden was significantly higher than that in non-culprit vessels (in men 48% ± 6%, P < 0.001 as compared to non-culprit vessels; in women 44% ± 18%, P = 0.004 as compared to non-culprit vessels). Plaque burden of culprit vessels did not significantly change during aging (plaque burden in men of the highest age tertile 51% ± 9%, P = 0.523 as compared to lowest age tertile; in women of the highest age tertile 49% ± 8%, P = 0.449 as compared to lowest age tertile). In men, plaque morphology of culprit vessels became increasingly rupture-prone during aging (increasing percentages of necrotic core and dense calcium), whereas plaque morphology in non-culprit vessels was less rupture-prone and remained constant during aging. In women, necrotic core in non-culprit vessels was very low at young age, but increased during aging resulting in a plaque morphology that was very similar to men. Plaque morphology in culprit vessels of young women and men was similar. CONCLUSION This study provides evidence that age- and gender-related differences in plaque burden and plaque composition significantly depend on whether the vessel contained a non-culprit or culprit lesion.

Does Social Support Really Help to Eat a Low-Fat Diet? Main Effects and Gender Differences of Received Social Support within the Health Action Process Approach

BACKGROUND: Most theories of health-behavior change focus exclusively on individual self-regulation without taking social factors, such as social support, into account. This study's first aim was to systematically test the added value of received instrumental and emotional social support within the Health Action Process Approach (HAPA) in the context of dietary change. In the social support literature, gender effects emerge with regard to the effectiveness of social support. Thus, a second aim was the examination of gender differences in the association of social support with dietary behavior. METHODS: Participants were 252 overweight and obese individuals. At baseline and 12 months later, participants completed questionnaires on HAPA variables; diet-specific received social support and low-fat diet. RESULTS: For the prediction of intentions 12 months later, instrumental support was more beneficial for men than for women over and above individual self-regulation. In terms of dietary behavior at T2, a moderate main effect of instrumental support emerged. Moreover, received emotional social support was beneficial for men, but not for women in terms of a low-fat diet 12 months later. CONCLUSIONS: Effects of received instrumental social support found in this study provide new evidence for the added value of integrating social support into the HAPA.

Modulation of anticipatory emotion and perception processing by cognitive control.

Strategies of cognitive control are helpful in reducing anxiety experienced during anticipation of unpleasant or potentially unpleasant events. We investigated the associated cerebral information processing underlying the use of a specific cognitive control strategy during the anticipation of affect-laden events. Using functional magnetic resonance imaging, we examined differential brain activity during anticipation of events of unknown and negative emotional valence in a group of eighteen healthy subjects that used a cognitive control strategy, similar to "reality checking" as used in psychotherapy, compared with a group of sixteen subjects that did not exert cognitive control. While expecting unpleasant stimuli, the "cognitive control" group showed higher activity in left medial and dorsolateral prefrontal cortex areas but reduced activity in the left extended amygdala, pulvinar/lateral geniculate nucleus and fusiform gyrus. Cognitive control during the "unknown" expectation was associated with reduced amygdalar activity as well and further with reduced insular and thalamic activity. The amygdala activations associated with cognitive control correlated negatively with the reappraisal scores of an emotion regulation questionnaire. The results indicate that cognitive control of particularly unpleasant emotions is associated with elevated prefrontal cortex activity that may serve to attenuate emotion processing in for instance amygdala, and, notably, in perception related brain areas.

The impact of body mass index and gender on the development of infectious complications in polytrauma patients

Purpose The aim was to test the impact of body mass index (BMI) and gender on infectious complications after polytrauma. Methods A total of 651 patients were included in this retrospective study, with an Injury Severity Score (ISS) C16 and age C16 years. The sample was subdivided into three groups: BMI\25 kg/m2, BMI 25–30 kg/m2, and BMI[30 kg/m2, and a female and a male group. Infectious complications were observed for 31 days after admission. Data are given as mean ± standard errors of the means. Analysis of variance, Kruskal–Wallis test, v2 tests, and Pearson’s correlation were used for the analyses and the significance level was set at P\0.05. Results The overall infection rates were 31.0 % in the BMI\25 kg/m2 group, 29.0 % in the BMI 25–30 kg/m2 group, and 24.5 % in the BMI[30 kg/m2 group (P = 0.519). The female patients developed significantly fewer infectious complications than the male patients (26.8 vs. 73.2 %; P\0.001). The incidence of death was significantly decreased according to the BMI group (8.8 vs. 7.2 vs. 1.5 %; P\0.0001) and the female population had a significantly lower mortality rate (4.1 vs. 13.4 %; P\0.0001). Pearson’s correlations between the Abbreviated Injury Scale (AIS) score and the corresponding infectious foci were not significant. Conclusion Higher BMI seems to be protective against polytrauma-associated death but not polytrauma-associated infections, and female gender protects against both polytrauma- associated infections and death. Understanding gender-specific immunomodulation could improve the outcome of polytrauma patients.

Gender-fair language use in online job advertisements - relations to job status and gender equality

Purpose Gender fair language use in job advertisements has been shown to impact the outcome of personnel selections. It is thus important to assess, to what extent gender fair language is used in job advertisements and with which factors it is associated, e.g., language, culture, status, and gender typicality of profession. Design/Methodology In the present research we investigated gender fair language use in job advertisements published online in four European countries with different socio-economic rankings of gender equality (World Economic Forum, 2011), namely Austria (rank 34), Czech Republic (75), Poland (42), and Switzerland (10). From four lines of business with different percentages of female employees – steels/metals, science, restaurants/food services, and health care –we randomly selected 100 job advertisements, summing up to 1600 job advertisements in total. Results A first analysis of the Swiss data indicates that the phrasing of job advertisements is closely related to a profession’s gender typicality (e.g., merely masculine forms are used in steels and metals, gender-fair forms in healthcare). Feminine forms however are almost never used. Cross-cultural comparisons will be presented. Limitations We analyzed job advertisements of four specific lines of business in four European countries. To what extend results can be generalized remains an open question. Research/Practical Implications The present data provide a sound basis for future studies on gender fair language use in job advertisements. Furthermore it sheds a light on how companies comply with national guidelines of gender equality. Originality/Value This is the first time that gender fair language use in job advertisements is investigated (a) across different countries and languages and (b) considering status and gender typicality of professions.

Gender references in job advertisements – relations to job status and gender equality

Research has shown that gender references in job advertisements play an important role for gender (in)equality in personnel selection. The use of pair forms (masculine and feminine form) in German-language job advertisements, for example, was found to reduce the lack of fit between women and leadership roles (Horvath & Sczesny, 2013). Therefore the present study addresses the question which forms of gender reference are used in job advertisements, how these forms are distributed in different countries and how language use is related to gender typicality and status of the job. We collected job advertisements published online in four countries with different rankings of gender equality (i.e., Switzerland, Austria, Poland, and Czech Republic; World Economic Forum, 2011). We randomly selected 100 advertisements per country from four branches that are characterized by different proportions of female and male employees: steels/metals, science, restaurants/food services, and health care. The advertisements were analyzed with regard to gender references as well as different indicators of job status. The results show that, in general, men and women are addressed more equally in Swiss and Austrian job advertisements compared to Polish and Czech job advertisements. The results also show that women and men are addressed more equally in branches where the proportion of women is high than where the proportion of women is low. We thus can conclude that the use of gender references is associated with the degree of gender equality achieved in a country and with the gender typicality of a profession.

Cohort and Gender Differences in Psychosocial Adjustment to Later-Life Widowhood

Objectives. Despite the large body of literature on bereavement, little is known about the impact of sociohistorical context on individual reactions to spousal loss. This study examines the effect of marital status, time period and gender on physical and mental health, and whether reported difficulties following spousal loss differ at 2 distinctive time periods. Method. Two cohorts of older bereaved persons (n = 753) in Switzerland, surveyed in 1979 and 2011, were compared regarding their reports of difficulties related to marital loss. The bereaved spouses were also compared with a group of married contemporaries (n = 1,517) regarding subjective health and depressive symptoms. Results. Marital status and gender each have independent effects on subjective health and depressive symptoms. The effects of widowhood on subjective health differed significantly at both time points. Widowed individuals in 2011, especially women, reported fewer social and financial difficulties than their counterparts in 1979. However, the effect of widowhood on depressive symptoms and psychological difficulties did not differ significantly across time points. Discussion. Social changes in the late 20th century may be protective for older adults’ physical, social, and financial well-being in the face of spousal loss, yet these changes do not alleviate widow(er)s’ psychological distress.
