Stress habituation,body shape and cardiovascular mortality

High cardiovascular mortality is well documented in lean phenotypes exhibiting visceral fat accumulation. In contrast, corpulent phenotypes with predominantly subcutaneous fat accumulation display a surprisingly low mortality. The term ‘obesity paradox’ reflects the difficulty in understanding the biological mechanisms underlying these clinical observations. The allostatic load model of chronic stress focuses on glucocorticoid dysregulation as part of a ‘network of allostasis’ involving autonomic, endocrine, metabolic, and immune mediators. Here, we expand upon the energetic demands of the brain and show that ‘habituators’ and ‘non-habituators’ develop divergent patterns of fat distribution. Central to this process is the recurrent rise in the cerebral energy need (arousal) that non-habituators experience during chronic stress. These neuroenergetic alterations promote visceral fat accumulation, subcutaneous fat loss, and atherogenesis with subsequent cardiovascular events. Habituators are more or less protected against such cardiovascular complications, but there is a metabolic trade-off that we shall discuss in the present paper.

Evaluating the inhibitory potential of Withania somnifera on platelet aggregation and inflammation enzymes: An in vitro and in silico study

Context Withania somnifera (L.) Dunal is traditionally used for treating various ailments, but lacks scientific evaluation.

Objective This study evaluates Withania somnifera (WS) for its effect on platelet activity and inflammatory enzymes.

Materials and methods Aqueous and ethanolic (1:1) leaf extracts were subjected to in vitro indirect haemolytic activity using Naja naja venom, human platelet aggregation was quantified for lipid peroxidation using arachidonic acid (AA) as agonist and 5-lipoxygenase (5-LOX) levels were determined using standard spectrometric assays. Further, molecular docking was performed by the ligand fit method using molegro software package (Molegro ApS, Aarhus, Denmark).

Results The study found that aqueous and ethanol extracts have very negligible effect (15%) with an IC₅₀ value of 13.8?mg/mL on PLA₂ from Naja naja venom. Further, extracts of WS also had very little effect (18%) with an IC₅₀ value of 16.6?mg/mL on malondialdehyde (MDA) formation. However, a 65% inhibition of 5-LOX with an IC₅₀ value of 0.92?mg/mL was observed in 1:1 ethanol extracts. The same was evident from SAR model with the active ingredient withaferin A binding predominantly on Phe 77, Tyr 98, Arg 99, Asp 164, Leu 168, Ser 382, Arg 395, Tyr 396 and Tyr 614 with an atomic contact energy value of??128.96 compared to standard phenidone (?103.61). Thus, the current study validates the application of WS for inflammatory diseases.

Conclusion This study reveals the inhibitory potential of W. somnifera on inflammatory enzymes and platelet aggregation. Thus, WS can serve as a newer, safer and affordable medicine for inflammatory diseases.     

A mechanism for gratitude development in a child

Most scholars consider gratitude as a moral emotion, with only few seeing it as a character trait. As a result, no systematic mechanism has ever been attempted to develop gratitude in children. Given the social issue of widespread lack of gratitude in the one-child generations of China, this article attempts to outline a mechanism of parental moral education for gratitude development. The mechanism is underpinned by love, induction and discipline; and theoretically justified in accordance with key psychological and sociological theories, such as Piaget's theory of moral development, Kohlberg's moral stages theory, attachment theory, Hoffman's internalisation theory, Rest's social justice theory and Baumrind's parenting styles theory. The benefits and potential risks of each strategy of the mechanism are addressed.     

Les théories du complot : l’envers du mythe totémique dans le lien social

ObjectivesThe current explosion of conspiracy theories is an undeniable dimension of present-day social bonds. We aim to understand some of the unconscious stakes underlying the conspiratorial ideation and to shed light upon the reasons why it is a topical issue in our modern society.MethodsBy relying on psychoanalytical knowledge that allows us to study the psychic functions of the myth, we will compare different conspiracy formations to those of the mythical narrative to bring into resonance these two fictional modalities. Freud's totemic myth, through its structure, sheds a particular light on the functions that regulate jouissance and that organize history, as well as social bonds.ResultsThe conspiracy discourse will prove to be the underside of the Freudian myth of Totem and Taboo. The text presenting the myth of the primal horde will reveal the structure of the conspiracy discourse as its negative. Indeed, this myth offers a symbolic ur-fiction, and its imaginary counterpart determines the conspiratorial grammar based on the question: “who profits from the crime?” As in a hall of mirrors, the countless conspiracies will appear as the shadow of a crime, always returning in an imaginary mode due to a lack of symbolization. The system that the conspiracy theory seeks to unveil will then be regarded as the reverse of an arrangement structured by the myth.DiscussionWe discuss the link between scientific discourse and the intensification of conspiracy theories’ presence in our modern society. Indeed, Lacan notices how the mythical dimension is repressed by scientific discourse. Such repression would produce, as a result, imaginary versions of the myth. Thus, the conspiracy theory will be regarded as a structural effect of scientific discourse rather than as anti-science.ConclusionsThe conspiracy theory turns out to be a social symptom linked to scientific discourse. It is the social staging of damage suffered that transforms the coordinates of a symbolic loss, no longer organized by a myth, into an imaginary stolen jouissance.     

我国部分三级综合医院护理质量管理组织架构调查与分析

目的调查我国三级综合医院护理质量管理组织架构。方法对全国85所医院相关护理人员进行问卷调查,并采用半结构式访谈法对其中11所医院护理质量管理专家进行访谈。结果90.6%的医院护理质量管理采用三级管理;85所医院均设有护理质量管理委员会,其中9.4%的委员会中缺少护士长参与,54.1%的护理质量管理委员会由护理队伍独立组成;访谈资料归纳出3个主题为;护理质量管理组织架构和运行方式较成熟,但仍需改进;希望多部门共同参与护理质量管理以及对目前护理质量管理组织架构的建议。结论建议优化护理质量管理三级模式和运行方式,建立多部门合作机制.鼓励护士长参与质量控制,并根据医院自身实际调整护理质量管理架构,以促进护理质量持续改进。     

Implementation of Telehealth: Normalization Process Theory and NoMAD-Ex.

This nurse practitioner–led project facilitated integration of telehealth services in a women’s clinic. Normalization Process Theory and the Normalization Measures Development (NoMAD) instrument were identified as tools. The NoMAD survey was augmented with a request for 2–3 sentences of explanation for each item. These data were then evaluated using inductive content analysis to identify specific facilitators and barriers. Results were presented to an interdisciplinary team charged with the responsibility of making modifications to the existing telehealth workflow. The resultant workflow was piloted for 30 encounters and statistically significant improvement in average NoMAD score was demonstrated on repeat survey.
