Cardiovascular complications of liver cirrhosis include cardiac dysfunction and abnormalities in the central-, splanchnic,- and peripheral circulation. Vasodilatation prevails, but vascular beds with various degrees of reduced and increased haemodynamic resistance are the results of massive activation of powerful homeostatic, regulatory systems. Cirrhotic cardiomyopathy implies systolic and diastolic dysfunction and electrophysiological abnormalities, an entity that is different from alcoholic heart muscle disease. Being often clinical latent, cirrhotic cardiomyopathy can be unmasked by physical and pharmacological strain. Cardiac failure is an important cause of mortality after liver transplantation and stressful procedures as insertions of transjugular intrahepatic portal systemic shunt (TIPS), peritoneal venous shunting, and other types of surgery. Improvement of liver function has been shown to reverse the cardiovascular complications. The clinical significance is an important topic for future research. At present, no specific treatment can be recommended, and the cardiac failure in cirrhosis should be treated as in non-cirrhotic patients with sodium restriction, diuretics, and beta-adrenergic blocking agents. Special care should be taken with the use of ACE-inhibitors and angiotensin antagonist in these patients. 相似文献

Cardiac allograft vasculopathy (CAV) causes heart failure after heart transplantation (HTx), but its pathogenesis is incompletely understood. Notch signaling, possibly modulated by everolimus (EVR), is essential for processes involved in CAV. We hypothesized that circulating Notch ligands would be dysregulated after HTx. We studied circulating delta‐like Notch ligand 1 (DLL1) and periostin (POSTN) and CAV in de novo HTx recipients (n = 70) randomized to standard or EVR‐based, calcineurin inhibitor‐free immunosuppression and in maintenance HTx recipients (n = 41). Compared to healthy controls, plasma DLL1 and POSTN were elevated in de novo (P < .01; P < .001) and maintenance HTx recipients (P < .001; P < .01). Use of EVR was associated with a treatment effect for DLL1. For de novo HTx recipients, a change in DLL1 correlated with a change in CAV at 1 (P = .021) and 3 years (P = .005). In vitro, activation of T cells increased DLL1 secretion, attenuated by EVR. In vitro data suggest that also endothelial cells and vascular smooth muscle cells (VSMCs) could contribute to circulating DLL1. Immunostaining of myocardial specimens showed colocalization of DLL1 with T cells, endothelial cells, and VSMCs. Our findings suggest a role of DLL1 in CAV progression, and that the beneficial effect of EVR on CAV could reflect a suppressive effect on DLL1.

To describe patterns of leisure time physical activity during pregnancy in relation to pre-pregnancy leisure time physical
activity, socio-demographic characteristics, fertility history, and lifestyle factors. 4,718 nulliparous with singleton pregnancy
and intended spontaneous vaginal delivery were included in the study at gestational week 33 from May 2004 to July 2005. Information
was provided by self-administered questionnaires. Leisure time physical activity was categorised into four categories: competitive
sport, moderate-to-heavy, light or sedentary. In this population of nulliparous women, 4% participated in competitive sport,
25% in moderate-to-heavy activities, 66% in light activities, and 5% in sedentary activities in the year prior to pregnancy.
Physical activity before pregnancy was statistically significantly associated with age, pre-pregnancy BMI, chronic diseases,
number of years at school, and smoking habits. The proportion of women who took part in competitive sports, and moderate-to-heavy
activities decreased over the three trimesters of pregnancy. The proportion of women with light physical activity was stable
during pregnancy while the proportion of women with sedentary activity increased from 6% to 29%. During the third trimester
women performing competitive sports or moderate-to-heavy activities before pregnancy continued to have a higher level of physical
activity than women with light activities or sedentary activities before pregnancy. In general the intensity and time spent
on exercise decreased during pregnancy. Women with the highest level of exercise prior to pregnancy continued to be the most
active during pregnancy. Among women with sedentary activities before pregnancy one-fourth changed to light activity during
pregnancy. 相似文献

The idea behind this article is to discuss the importance and to develop the concept of reciprocity in asymmetric professional relationships. As an empirical starting point for an examination of the possible forms of reciprocity between patients and nurses in psychiatry, we chose two qualitative in-depth interviews with two different patients. The manners in which these two patients relate to medical personnel??one is dependent, the other is independent??show that this presents challenges to nurses. The theoretical context is provided by the notion of mature care as it has been developed by feminist-oriented ethics of care, in contrast to the notion of altruistic care. In relation to the concept of mature care, we discuss how nursing can be perceived in demanding relationships with patients in psychiatry. Reciprocity implies that, in principle, the interests of the nurses also matter in a nurse-patient relationship. We show that reciprocity??in practice??is complicated and challenging in a number of different ways. Mature care??with its systematic inclusion of relationships and reciprocity??provides an alternative understanding of what takes place between patients and nurses compared with an altruistic notion of care. As such, mature care can be regarded as an useful paradigm for nurse-patient relationships in psychiatry. 相似文献
