Background: This meta-review aimed to synthesize the evidence of the effects of exercise on anxiety and depression symptoms amongst adults with cancer, and cancer-survivors, comparing effects sizes between meta-analysis.

Methods: Major databases were searched up to February 9, 2024 for meta-analyses evaluating the effects of exercise, using anxiety and/or depression scales. Effect size (ES) values were calculated as standardized differences in the means and expressed as the Standardized Mean Difference (SMD) with the 95% confidence interval (95%CI).

This randomized controlled trial investigated the effectiveness of an affect-adjusted, supervised, multimodal, online, and home-based exercise group protocol as an adjunct therapy to antidepressants on depressive symptoms, cardiorespiratory fitness, and side effects related to antidepressants in adults with major depression (MDD, diagnosed by a clinician). Depressive symptom scales were administered by a psychiatrist and self-reported. A health-related measure (i.

We investigated whether mood and lifestyle-related indicators of physical health are differentially expressed according to self-reported levels of depressive symptoms among young adults with a current episode of major depression. In a cross-sectional study, we recruited 94 young adults (females = 67, 71.3%; males = 27, 28.

Cognitive performance is usually impaired in those with serious mental illness (SMI). Exercise may improve cognitive functioning, but studies examining the effects of exercise in SMI indicate heterogenous findings. To estimate the effects of exercise on cognitive outcomes in people with SMI.

Introduction: The understanding of biological responses to psychedelics with antidepressant potential is imperative. Here we report how a set of acute parameters, namely emotional (depressive symptoms), cognitive (psychedelic experience), and physiological (salivary cortisol), recorded during an ayahuasca dosing session, modulated serum brain-derived neurotrophic factor (BDNF), serum cortisol (SC), serum interleukin 6 (IL-6), plasma C-reactive protein (CRP), and salivary cortisol awakening response (CAR).

Methods: Results were analyzed 2 days after the psychedelic intervention (ayahuasca) versus placebo in both patients with treatment-resistant depression and healthy volunteers.

Observational studies of long-term users of ayahuasca, an Amazonian psychedelic brew, suggest an increase in resilience improvements in emotion and cognition. Ayahuasca has also demonstrated clinical antidepressant effects in human and animal studies; however, its potential prophylactic action in depression has not been previously studied. Therefore, this experimental study sought to evaluate the potential prophylactic effects of repeated and long-term ayahuasca use, the modulation of resilience, in a non-human primate animal model, , subjected to a protocol for induction of depressive-like behavior.

Mental health burden has been massively reported during the COVID-19 pandemic period. Aiming to summarise these data, we present a meta-review of meta-analyses that evaluated the impact of COVID-19 pandemic on anxiety, depressive and stress symptoms, psychological distress, post-traumatic stress disorder/symptoms (PTSD), and sleep disturbance, reporting its prevalence on general public (GP) and health care workers (HCW). A search was performed in the PubMed, EMBASE, and the Web of Science.

The comprehension of the pathophysiology of the major depressive disorder (MDD) is essential to the strengthening of precision psychiatry. In order to determine the relationship between the pathophysiology of the MDD and its clinical progression, analyzed by severity of the depressive symptoms and sleep quality, we conducted a study assessing different peripheral molecular biomarkers, including the levels of plasma C-reactive protein (CRP), serum mature brain-derived neurotrophic factor (mBDNF), serum cortisol (SC), and salivary cortisol awakening response (CAR), of patients with MDD ( = 58) and a control group of healthy volunteers ( = 62). Patients with the first episode of MDD ( = 30) had significantly higher levels of CAR and SC than controls ( = 32) and similar levels of mBDNF of controls.

The stress response comprises a phylogenetically conserved set of cognitive, physiological, and behavioral responses that evolved as a survival strategy. In this context, the memory of stressful events would be adaptive as it could avoid re-exposure to an adverse event, otherwise the event would be facilitated in positively stressful or non-distressful conditions. However, the interaction between stress and memory comprises complex responses, some of them which are not yet completely understood, and which depend on several factors such as the memory system that is recruited, the nature and duration of the stressful event, as well as the timing in which this interaction takes place.

Background: Psychological distress in University settings has grown and became a public health concern. In this context, contemplative practices such as mindfulness have been proposed as a strategy to help students on stress management.

Methods: Forty university students (20 female), aged between 18 to 30 years (mean = 24.
