Age-related effects of blood pressure on everyday cognitive function in community-dwelling women

ABSTRACT

Objectives: Blood pressure is an indicator of vascular health that has been associated with cognition and quality of life in older age. Few studies have examined blood pressure across everyday cognitive tasks, which may have superior predictive functional utility than traditional cognitive measures. We explored blood pressure as a predictor of everyday problem solving (EPS) performance in middle-aged and older women. Method: Community-dwelling women (age: 51–91) with low-normal blood pressure to mild hypertension underwent traditional and everyday cognitive testing. EPS was determined by the number of safe/effective solutions generated for real-world scenarios. Results: Analyses revealed that lower systolic blood pressure and pulse pressure were associated with worse EPS ability after controlling for age, education, and traditional cognitive abilities. Discussion: These results support that blood pressure may be an important predictor of everyday cognitive abilities in older age. Potential implications for real-world functioning are discussed.

The veneration of the Precious Blood in Weingarten: theological reflections in an ecumenical horizon

This article places the veneration of the Precious Blood in Weingarten in the wider horizon of the veneration of relics and saints in general. It takes into account that the Reformers, above all Martin Luther, were very critical about pilgrimages and the veneration of relics. Against this background it discusses the following points with regard to the veneration of the Precious Blood. First, what is the added value of pilgrimages? Secondly, what, or rather, who, is being venerated in what way in Weingarten? Thirdly, what is theologically legitimate in venerating a relic of the Precious Blood and could render it ecumenically justifiable? And, fourthly, what is the current meaning of the veneration of the Precious Blood? Answering these questions is vital for keeping the veneration of the Precious Blood in Weingarten a living tradition – especially in a time without a monastery.     

The Precious Blood of Christ: faith,rituals and civic and religious meaning during the centuries of Mantuan devotion

This article explores the main meanings given to the presence of the relic of the Precious Blood of Christ in the city of Mantua, and also highlights the links with the Altdorf-Weingarten relic of the same, which derives from it. For centuries the presence of this relic has intertwined in several ways with events in Mantua and has shaped some of their most significant religious and cultural expressions. Above all, during the Middle Ages, the Precious Blood had a widespread impact, destined to expand all over Europe. However, we possess vague and scarcely defined evidence of this, as much of the evidence was removed, mostly in the name of rationalist critique, and diminished with the passing of time. Within a long-term perspective, the text which follows here aims to tackle some relevant problematic issues, from a historical and historico-anthropological viewpoint. It attempts both to strengthen understanding of the local and wider intertwining which characterised the development of such a relevant religious experience of our culture, and also to enter into contact with essential aspects of it.     

齐"巫儿婚俗"再探讨

文献所谓“襄公淫乱,姑姊妹不嫁”以及桓公“妻姑姊妹”不能够成立,齐襄公、桓公的淫乱属于婚外性关系而非兄妹血缘婚.春秋齐国社会已不承认并且谴责非婚乱伦关系,故不可能由襄、桓淫乱导致“巫儿婚俗”.齐女居家不嫁的“巫儿婚俗”不是宫廷和民间普遍存在的状况,只是部分大家庭出于迷信观念而保留经常性祭祀活动的一种特殊现象.所谓“齐俗,妇人首祭祀”,一般是以家庭生活为内容的小祭祀,古已有之,并非齐女垄断了家庭、家族的祭祀活动.     

一名宗教信仰者输血引发的思考

输血挽救了无数危重患者的生命,但少数宗教信仰者在自己或其家属急需输血时却拒绝输血治疗,而目前我国的法律法规在这一方面尚无明确规定,在此种情况下是否输血,医师处于两难的选择,也较易引起医患纠纷,为此建议我国卫生及其司法部门尽快制定相关法律法规,使医务工作者,在遇到此类问题时有章可循,有法可依。     

Facing Ourselves

At the time of this writing, a widely publicized, waived-consent trial is underway. Sponsored by Northfield Laboratories, Inc. (Evanston, IL) the trial is intended to evaluate the emergency use of PolyHeme^®, an oxygen-carrying resuscitative fluid that might prevent deaths from uncontrolled bleeding. The protocol allows patients in hemorrhagic shock to be randomized between PolyHeme^® and saline in the field and, still without consent, randomized between PolyHeme^® and blood after arrival at an emergency department. The Federal regulations that govern the waiver of consent restrict its applicability to circumstances where proven, satisfactory treatments are unavailable. Blood—the standard treatment for hemorrhagic shock—is not available in ambulances but is available in hospitals. The authors argue that the in-hospital stage of the study fails to meet ethical and regulatory standards.
