Free- radicals (Oxygen and Nitrogen species) are formed in mitochondria during the oxidative phosphorylation. Their high reactivity, due to not-engaged electrons, leads to an increase of the oxidative stress. This condition affects above all the brain, that usually needs a large oxygen amount and in which there is the major possibility to accumulate “Reacting Species.” Antioxidant molecules are fundamental in limiting free-radical damage, in particular in the central nervous system: the oxidative stress, in fact, seems to worsen the course of neurodegenerative diseases. The aim of this review is to sum up natural antioxidant molecules with the greatest neuroprotective properties against free radical genesis, understanding their relationship with the Central Nervous System.
(1) Background: Functional Hypothalamic Amenorrhea (FHA) can be caused by the hyper activation of neuro-endocrine responses to stress. Among other endocrine factors and hypothalamic dysfunctions, the psychophysiological stress response can very frequently lead to an inhibition of the gonadal–pituitary axis. The aim of this study was to investigate the level of neurovegetative activation in a group of young women affected by this condition. (2) Methods: Twenty-five women (mean age = 21.1 ± 4.34) with FHA were consecutively recruited. Information on psycho-physiological distress was collected through a Psychopathological assessment (with the administration of three psychometric tests) and the Psychophysiological Stress Profile (PSP). Their data were compared with a control group. (3) Results: In the PSP, the patients displayed significantly higher values compared to controls in terms of the parameters of muscle tension (sEMG), skin conductance (SCL/SCR), heart rate (HR), and peripheral temperature (PT). Furthermore, autonomic hyper-activation at rest, marked reactivity to stress, and reduced recovery were seen. Moreover, a condition characterized by psychological distress (anxiety and somatic complaints, depressed and irritable mood, obsessive-compulsive traits) emerged. (4) Conclusions: The results highlight autonomic hyper-activation in FHA, which is also associated with psychological distress. Considering that FHA is a condition that affects multiple systems between mind and body, a multimodal, multidimensional, and multidisciplinary assessment of stress is becoming an emerging need.
Objective: This preliminary study focused on the description of some dysfunctional perceptions of the body image and eating habits in a sample of young. Methods: The results obtained by 55 amateur and professional volleyball players belonging to volleyball sports clubs located in the province of Reggio Emilia were examined. The age of the sample is in a range between 11 and 44 years. The participants completed the Pisa Survey for Eating Disorders (PSED), a questionnaire aimed at examining eating behavior and the perception of one’s body image. The athletes’ height and body weight were subsequently detected through direct measurement. Conclusion: The data collected through the self-evaluation questionnaire and the measurements carried out by the study made it possible to analyze the perception of the body image and the eating habits of the volleyball players belonging to the sample and to compare them with the data in the literature. The data, albeit preliminary, allow us to confirm the existence of the discrepancy between the real body image and the desired one, in a group of young athletes, who favors the adoption of non-adaptive coping strategies to control one’s own weight and body shapes typical of the vicious circle - strict diet, bingeing episodes, compensatory behaviors - which characterizes eating disorders (ED). It is therefore considered essential that body image assessment is a practice implemented in the assessment routine of these athletes, especially in consideration of the fact that body image disturbance is a very common feature in this category and is one of the main risk factors of EDs.
Stress is a psychophysical condition that causes an impairment in athletes’ performance by causing an increase in sympathetic activity and an autonomic imbalance. The current methods for the measurement of psychophysiological stress introduce the use of the heart rate variability as a useful index of the well-being of these people. The heart rate variability corresponds to the time intervals between consecutive heartbeats, such as an irregularity in the normal sinus heart rhythm whose variability is due to the control exercised by a complex system of mechanisms, including the respiratory control system, and provides information about the activity of the sympathetic and parasympathetic branches of the autonomic nervous system. This review aims at summarizing the promising results, despite small amount, of the recent literature on the efficacy of heart rate variability biofeedback on the autonomic imbalance and psychophysical well-being of athletes as well as cognitive and motor performance.
(1) Background: A new mental illness is attracting the attention of researchers and mental health professionals. Orthorexia nervosa (ON) is a possible new mental disorder, the main symptom of which is an obsessive and insecure focus on healthy foods and consequent compulsive behaviors. There is a common consensus among researchers that ON is considered partly overlapping with obsessive–compulsive disorders (OCDs). (2) Methods: MEDLINE and Scopus were searched for articles published in the last 10 years regarding the psychophysiological aspects of OCD and ON. Eight studies met the eligibility criteria. The inclusion criteria encompassed adults diagnosed with OCD and/or ON. However, only studies involving OCD patients were found. (3) Results: Some research groups have shown that OCD disorders can be considered among anxiety disorders because they are characterized by anxious hyper activation. Other research, however, has shown profiles characterized by low psychophysiological reactivity to stressful stimuli. Despite this, there seems to be a consensus on the poor inhibition abilities, even when activation is low, and the dissociation between cognitive and psychophysiological activation emerged. (4) Conclusions: However discordant, some points seem to bring the researchers to agreement. In fact, there is consensus on conducting a multidimensional assessment that can measure all of the aspects of suffering (cognition, emotion, and behavior) and highlight the poor body–mind integration. This clinical approach would make it possible to propose interventions aimed at treating some mental illnesses such as food obsession that can paradoxically impair the psychophysical balance. Nevertheless, the applied systematizing approach to existing studies on ON is very much needed for better understanding of the psychophysical nature of this new mental illness and its implications for prevention and treatment.
The use of contrast media in clinical diagnostic practice has increased significantly in recent years, accompanied by an increase in adverse reactions. These are the fleeting symptoms most complained about by patients: Flushing of the face, feeling of nausea, and heat lasting a few seconds, considered side effects related to the drug. Hypersensitivity reactions are rarer but dangerous and are driven by the immune system. To ensure the optimal management of adverse reactions to iodinated contrast media, various types of health specialists, such as radiologists, are looking into how to deal with the problem. While there are many suggestions in the scientific literature on what to do in the case of important reactions during or after radiological examination, unfortunately, there are no studies on primary and secondary prevention and, in particular, on psychophysical and psychophysiological influences. Some inferences could be made by observing the studies about psychophysiological stress and immune-inflammatory processes of allergies. The few studies in the literature on the analysis of processes affecting both psychophysiological stress and allergic responses have been analyzed. Finally, stress measurement methods are proposed that can highlight “hypersensitive” people with physiological characteristics capable of exacerbating or accentuating an allergic reaction to contrast media.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
