Chronic stress and early recurrence of takotsubo cardiomyopathy: A clinical case
2014
Takotsubo cardiomyopathy (TC) is characterized by transient systolic dysfunction of the apical and middle segments of the left ventricle, accompanied by electrocardiographic abnormalities and mild elevation of cardiac biomarker levels in the absence of obstructive coronary artery disease. The following case is of a woman suffering from chronic emotional stress with a very early recurrence. An acute trigger event was not detectable in both cases. It is possible to suppose that, in predisposed subjects, chronic stress by increasing sympathetic activity may be considered not only a trigger for TC, but also a negative prognostic factor for early recurrence.
Definition, aims, and implementation of GA [sup] 2 LEN/HAEi Angioedema Centers of Reference and Excellence
2020
This document summarizes the aims of GA2 LEN/HAEi Angioedema Centers of Reference and Excellence (ACAREs) and elaborates the requirements that ACAREs must fulfill to become certified. It also provides (see Appendix S1) background information on GA2LEN and HAEi, including HAEi member organizations and regional patient advocates, on why we need an Angioedema Center of Reference and Excellence (ACARE) program and network, and on the accreditation and certification process, governance and funding, and on the interaction with other GA2LEN networks of centers of reference and excellence. The protocols, aims, requirements, and provisions related to becoming a certified CARE are based on (a) the ex…
P1462 Additive value of global longitudinal strain measurement in patients with known or suspected ischaemic heart disease undergoing stress echo
2020
Abstract BACKGROUND Speckle-tracking echocardiography (STE) can be applied in a large variety of clinical conditions. Global longitudinal strain (GLS) shows high diagnostic accuracy for the detection of myocardial ischemia as it reflects changes in subendocardial fibers deformation that are more exposed to ischemic damage, even before alterations in segmental kinetics are revealed. PURPOSE Aim of our study was to assess whether the measurement of global longitudinal strain during stress-echo can provide additional information compared to the assessment of conventional parameters such as left ventricular ejection fraction (LVEF) and wall motion abnormalities. We also evaluated the added valu…
P776 Stress ecocardiography and speckle tracking analysis in patients with heart failure and preserved ejection fraction
2020
Abstract BACKGROUND Heart failure with preserved ejection fraction (HFpEF) is characterized by heart failure symptoms despite preserved LV systolic function together with at least one among left ventricle hypertrophy/left atrial enlargement plus diastolic dysfunction (DD) and increased brain natriuretic peptide levels. Rest echocardiography could still be normal despite patients experience HF symptoms. Speckle tracking analysis (STE) analyzes myocardial deformation and is able to identify subtle left ventricular dysfunction. PURPOSE to analyze the added value of stress echocardiography to improve diagnostic accuracy in patients with normal ejection fraction and unexplained dyspnoea by evalu…
Pharmacological manipulation of serotonin receptors during brain embryogenesis favours stress resiliency in female rats
2018
Manipulations of the serotonin transmission during early development induce long-lasting changes in the serotonergic circuitry throughout the brain. However, little is known on the developmental consequences in the female progeny. Therefore, this study aimed at exploring the behavioural effects of pre- and postnatal stimulation of the serotonergic system by 5-methoxytryptamine in adolescent female rats on behavioural reactivity and anxiety- like phenotype. Our results show that perinatal 5- methoxythyptamine decreased total distance travelled and rearing frequency in the novel enviroment, and increased the preference for the centre of the arena in the open field test. Moreover, perinatal 5-…
Toxicity effects of the organic UV-filter 4-Methylbenzylidene camphor in zebrafish embryos
2019
Abstract Ultraviolet (UV) filters are widely used in personal care products and due to their lipophilicity these chemicals tend to bioaccumulate in the aquatic biota. 4-Methylbenzylidene camphor (4-MBC) is one of the most used UV-filters, and it is commonly detected in freshwater fish tissues. This substance is suspected to be an endocrine disruptor due to its interaction with Hypothalamus-Pituitary-Gonadal (HPG) and HP-Thyroid (HPT)-axis. The main objective of this study was to evaluate the effects of 4-MBC on apical endpoints, biochemical markers and on genes involved in endocrine pathways in Danio rerio. Zebrafish embryos were exposed to 4-MBC (0.083–0.77 mg/l) from 0 to 96 h post-fertil…
Oxytocin reduces romantic rejection-induced pain in online speed-dating as revealed by decreased frontal-midline theta oscillations
2021
Abstract Background Romantic rejection is an emotionally distressful experience profoundly affecting life, possibly leading to mental illness or suicide. Oxytocin (OT) is a neuropeptide widely implicated in reducing physical pain and negative emotions; however, whether OT has an effect on reducing intense social pain (e.g., romantic rejection) remains unknown. Here, we tested the effect of OT on social pain and investigated its role in the outcome evaluation phase of social decision-making. Methods Electroencephalographic recordings were obtained between August 2nd and October 20th, 2020 in Shenzhen University from 61 healthy participants in a double-blind, placebo-controlled study with a b…
From obesity to Alzheimer's disease through insulin resistance
2021
Alzheimer's disease is one of the most frequent forms of dementia. It is a progressive neurodegenerative disease, characterized by presence of amyloid plaques and neurofibrillary tangles in the brain. Obesity is regarded as abnormal fat accumulation with deleterious impact on human health. There is full scientific evidence that obesity and the metabolic comorbidities (e.g., insulin resistance, hyperglycaemia, and type 2 diabetes) are related to Alzheimer's disease and likely in the causative pathway. Numerous studies have identified several overlapping neurodegenerative mechanisms, including oxidative stress, mitochondrial dysfunction, and inflammation. In this review, we present how obesit…
Wine consumption and renal diseases: new perspectives.
2006
Investigations into the relation between wine consumption and kidney disease have been limited. Patients with chronic renal failure show accelerated atherosclerotic damage and, considering the well-known protective effect of wine on the cardiovascular system, moderate wine consumption might be advantageous. Oxidative stress and endothelial dysfunction, which are inter-related, play a role in the pathophysiology of many renal diseases, including acute and chronic renal failure. Ethanol and non-alcoholic wine components, especially polyphenols, influence oxidative balance and endothelial function. Although long-term alcohol abuse has been associated with many renal alterations in humans, in e…
Effects of alcohol-free beer on lipid profile and parameters of oxidative stress and inflammation in elderly women
2009
We assessed the influence of alcohol-free beer on factors implicated in atherosclerosis, such as lipid profile, oxidative stress parameters, and proinflammatory cytokines, in postmenopausal women, a population particularly at risk for atherosclerotic disease.The study was carried out in 29 nuns, 58 to 73 y old, who live in a convent with a disciplined, regular, and homogeneous lifestyle. The nuns maintained their habits and diet routine, but their meals were supplemented with 500 mL/d of alcohol-free beer (0.0%) divided into two doses over a 45-d period. Lipid profile, inflammatory markers such as C-reactive protein, interleukins 1 and 6, and tumor necrosis factor-alpha, and parameters of o…
