Stress and Inflammation in Coronary Artery Disease: A Review Psychoneuroendocrineimmunology-Based.

Abstract: Recent findings have deeply changed the current view of coronary heart disease, going beyond the simplistic model of atherosclerosis as a passive process involving cholesterol build-up in the subintimal space of the arteries until their final occlusion and/or thrombosis and instead focusing on the key roles of inflammation and the immune system in plaque formation and destabilization. Chronic inflammation is a typical hallmark of cardiac disease, worsening outcomes irrespective of serum cholesterol levels. Low-grade chronic inflammation correlates with higher incidence of several non-cardiac diseases, including depression, and chronic depression is now listed among the most important cardiovascular risk factors for poor prognosis among patients with myocardial infarction. In this review, we include recent evidence describing the immune and endocrine properties of the heart and their critical roles in acute ischaemic damage and in post-infarct myocardial remodeling. The importance of the central and autonomic regulation of cardiac functions, namely, the neuro-cardiac axis, is extensively explained, highlighting the roles of acute and chronic stress, circadian rhythms, emotions and the social environment in triggering acute cardiac events and worsening heart function and metabolism in chronic cardiovascular diseases. We have also included specific sections related to stress-induced myocardial ischaemia measurements and stress cardiomyopathy. The complex network of reciprocal interconnections between the heart and the main biological systems we have presented in this paper provides a new vision of cardiovascular science based on psychoneuroendocrineimmunology.

Stress and the psyche–brain–immune network in psychiatric diseases based on psychoneuroendocrineimmunology: a concise review

Abstract: In the last decades, psychoneuroendocrineimmunology research has made relevant contributions to the fields of neuroscience, psychobiology, epigenetics, molecular biology, and clinical research by studying the effect of stress on human health and highlighting the close interrelations between psyche, brain, and bodily systems. It is now well recognized that chronic stress can alter the physiological cross-talk between brain and biological systems, leading to long-lasting maladaptive effects (allostatic overload) on the nervous, immune, endocrine, and metabolic systems, which compromises stress resiliency and health. Stressful conditions in early life have been associated with profound alterations in cortical and subcortical brain regions involved in emotion regulation and the salience network, showing relevant overlap with different psychiatric conditions. This paper provides a summary of the available literature concerning the notable effects of stress on the brain and immune system. We highlight the role of epigenetics as a mechanistic pathway mediating the influences of the social and physical environment on brain structure and connectivity, the immune system, and psycho-physical health in psychiatric diseases. We also summarize the evidence regarding the effects of stress management techniques (mainly psychotherapy and meditation practice) on clinical outcomes, brain neurocircuitry, and immune-inflammatory network in major psychiatric diseases.

Fatty acids profiling reveals potential candidate markers of semen quality

Abstract: Summary Previous reports showed altered fatty acid content in subjects with altered sperm parameters compared to normozoospermic individuals. However, these studies focused on a limited number of fatty acids, included a short number of subjects and results varied widely. We conducted a case–control study involving 155 patients allocated into four groups, including normozoospermia (n = 33), oligoasthenoteratozoospermia (n = 32), asthenozoospermia (n = 25), and varicocoele (n = 44). Fatty acid profiling, including 30 species, was analyzed by a validated gas chromatography (GC) method on the whole seminal fluid sample. Multinomial logistic regression modeling was used to identify the associations between fatty acids and the four groups. Specimens from 15 normozoospermic subjects were also analyzed for fatty acids content in the seminal plasma and spermatozoa to study the distribution in the two compartments. Fatty acids lipidome varied markedly between the four groups. Multinomial logistic regression modeling revealed that high levels of palmitic acid, behenic acid, oleic acid, and docosahexaenoic acid (DHA) confer a low risk to stay out of the normozoospermic group. In the whole population, seminal fluid stearic acid was negatively correlated (r = −0.53), and DHA was positively correlated (r = 0.65) with sperm motility. Some fatty acids were preferentially accumulated in spermatozoa and the highest difference was observed for DHA, which was 6.2 times higher in spermatozoa than in seminal plasma. The results of this study highlight complete fatty acids profile in patients with different semen parameters. Given the easy-to-follow and rapid method of analysis, fatty acid profiling by GC method can be used for therapeutic purposes and to measure compliance in infertility trials using fatty acids supplements.

Brief training of psychoneuroendocrinoimmunology-based meditation (PNEIMED) reduces stress symptom ratings and improves control on salivary cortisol secretion under basal and stimulated conditions.

Abstract: Context Meditation is proposed as an anti-stress practice lowering allostatic load and promoting well-being, with brief formats providing some of the benefits of longer interventions. Objectives PsychoNeuroEndocrinoImmunology-based meditation (PNEIMED) combines the teaching of philosophy and practice of Buddhist meditation with a grounding in human physiology from a systemic and integrative perspective. We evaluated the effects of four-day PNEIMED training (30h) on subjective and objective indices of stress in healthy adults. Design A non-randomized, controlled, before-and-after study was conducted. Participants ( n = 125, mostly health practitioners) answered a questionnaire rating stress symptom before (T0) and after (Tf) a PNEIMED course. In an additional sample ( n = 40; smokers, overweight persons, women taking contraceptives, and subjects with oral pathologies were excluded), divided into PNEIMED-attending (intervention, n = 21) and non-meditating (control, n = 19) groups, salivary cortisol was measured upon awakening and during a challenging mental task. Results Self-rated distress scores were highly reduced after the PNEIMED course. In the intervention group, improvement of psychological well-being was accompanied by decrease in cortisol levels at awakening. No T0-vs-Tf changes in distress scores and morning cortisol were found in controls. Based on baseline-to-peak increment of cortisol response at T0, 26 subjects ( n = 13 for each group) were classified as task-responders. The amplitude and duration of the cortisol response decreased after PNEIMED, whereas no effects were found in controls. Conclusions Brief PNEIMED training yields immediate benefits, reducing distress symptoms and adrenocortical activity under basal and stimulated conditions. PNEIMED may represent an effective practice to manage stress and anxiety, particularly among subjects facing a multitude of job-related stressors, such as healthcare workers.

A Brief Review of Cardiovascular Diseases, Associated Risk Factors and Current Treatment Regimes.

Abstract: Cardiovascular diseases (CVDs) are the leading cause of premature death and disability in humans and their incidence is on the rise globally. Given their substantial contribution towards the escalating costs of health care, CVDs also generate a high socio-economic burden in the general population. The underlying pathogenesis and progression associated with nearly all CVDs are predominantly of atherosclerotic origin that leads to the development of coronary artery disease, cerebrovascular disease, venous thromboembolism and, peripheral vascular disease, subsequently causing myocardial infarction, cardiac arrhythmias or stroke. The aetiological risk factors leading to the onset of CVDs are well recognized and include hyperlipidaemia, hypertension, diabetes, obesity, smoking and, lack of physical activity. They collectively represent more than 90% of the CVD risks in all epidemiological studies. Despite high fatality rate of CVDs, the identification and careful prevention of the underlying risk factors can significantly reduce the global epidemic of CVDs. Beside making favorable lifestyle modifications, primary regimes for the prevention and treatment of CVDs include lipid-lowering drugs, antihypertensives, antiplatelet and anticoagulation therapies. Despite their effectiveness, significant gaps in the treatment of CVDs remain. In this review, we discuss the epidemiology and pathology of the major CVDs that are prevalent globally. We also determine the contribution of well-recognized risk factors towards the development of CVDs and the prevention strategies. In the end, therapies for the control and treatment of CVDs are discussed.

Biomarkers in Stress Related Diseases/Disorders: Diagnostic, Prognostic, and Therapeutic Values.

Abstract: Various internal and external factors negatively affect the homeostatic equilibrium of organisms at the molecular to the whole-body level, inducing the so-called state of stress. Stress affects an organism's welfare status and induces energy-consuming mechanisms to combat the subsequent ill effects; thus, the individual may be immunocompromised, making them vulnerable to pathogens. The information presented here has been extensively reviewed, compiled, and analyzed from authenticated published resources available on Medline, PubMed, PubMed Central, Science Direct, and other scientific databases. Stress levels can be monitored by the quantitative and qualitative measurement of biomarkers. Potential markers of stress include thermal stress markers, such as heat shock proteins (HSPs), innate immune markers, such as Acute Phase Proteins (APPs), oxidative stress markers, and chemical secretions in the saliva and urine. In addition, stress biomarkers also play critical roles in the prognosis of stress-related diseases and disorders, and therapy guidance. Moreover, different components have been identified as potent mediators of cardiovascular, central nervous system, hepatic, and nephrological disorders, which can also be employed to evaluate these conditions precisely, but with stringent validation and specificity. Considerable scientific advances have been made in the detection, quantitation, and application of these biomarkers. The present review describes the current progress of identifying biomarkers, their prognostic, and therapeutic values.
