Mindfulness intervention effect on endometriosis-related pain dimensions and its mediator role on stress and vitality: a path analysis approach.

Endometriosis-related pain is supposedly mainly responsible for generating psychological stress and deteriorating the quality of life. However, the interaction between these factors has not been investigated, considering its multidimensional nature and through the path of effects of psychosocial approaches. The present study aims to investigate the effect of a brief mindfulness-based intervention (bMBI) on pain dimensions and its mediator role on psychological stress and QoL-Vitality improvement.

Mindfulness-Based Intervention Effect on the Psychophysiological Marker of Self-Regulation in Women With Endometriosis-Related Chronic Pain.

Endometriosis is a gynecological disease that involves a broad biopsychosocial compromise with the potential to create a negative vicious cycle. Despite the complexity of factors influencing women's improvement, most interventions investigated target just the peripheral nociceptive sources of endometriosis-related pain. An alternative is intervening in self-regulation, which can potentially influence multiple domains of the illness experience.

Cognitive-affective changes mediate the mindfulness-based intervention effect on endometriosis-related pain and mental health: A path analysis approach.

Background: There is poor knowledge about the therapeutic mechanisms of the conservative interventions for endometriosis. We hypothesized that the effects of a brief mindfulness-based intervention (bMBI) on pelvic pain intensity (PPI), pain unpleasantness (PU) and quality of life mental health (QoL-MH) are mediated by direct and indirect paths of changes in pain catastrophizing (PC), positive affect (PA) and negative affect (NA).

Methods: A secondary analysis of a pilot randomized controlled trial of women with endometriosis, assigned to standard medical treatment (n = 32) and standard medical treatment plus bMBI (n = 31).

Obliviate! Reviewing Neural Fundamentals of Intentional Forgetting from a Meta-Analytic Perspective.

Intentional forgetting (IF) is an important adaptive mechanism necessary for correct memory functioning, optimal psychological wellbeing, and appropriate daily performance. Due to its complexity, the neuropsychological processes that give birth to successful intentional forgetting are not yet clearly known. In this study, we used two different meta-analytic algorithms, Activation Likelihood Estimation (ALE) & Latent Dirichlet Allocation (LDA) to quantitatively assess the neural correlates of IF and to evaluate the degree of compatibility between the proposed neurobiological models and the existing brain imaging data.

A single-blind, randomized, pilot study of a brief mindfulness-based intervention for the endometriosis-related pain management.

Background: Women with endometriosis suffer from frequent symptoms despite multiple treatments in tertiary care. Although there is a need for a biopsychosocial perspective on endometriosis treatment, few conservative treatments have been investigated. We aimed to investigate the effects of a brief Mindfulness-Based Intervention (bMBI) in women with deep endometriosis who remain symptomatic despite undergoing conventional medical treatment.

Association between severity of pain, perceived stress and vagally-mediated heart rate variability in women with endometriosis.

Chronic pelvic pain is the main symptom in women with endometriosis. Evidence suggests that psychological stress and autonomic regulation contribute to symptoms and pathophysiological modulation. We investigated the relationship between endometriosis-related pain severity, perceived stress, and autonomic balance in a sample of 81 women suffering chronic pelvic pain with deep endometriosis.

Application of long-interval paired-pulse transcranial magnetic stimulation to motion-sensitive visual cortex does not lead to changes in motion discrimination.

The perception of visual motion is dependent on a set of occipitotemporal regions that are readily accessible to neuromodulation. The current study tested if paired-pulse Transcranial Magnetic Stimulation (ppTMS) could modulate motion perception by stimulating the occipital cortex as participants viewed near-threshold motion dot stimuli. In this sham-controlled study, fifteen subjects completed two sessions.

The challenge of forgetting: Neurobiological mechanisms of auditory directed forgetting.

Directed forgetting (DF) is considered an adaptive mechanism to cope with unwanted memories. Understanding it is crucial to develop treatments for disorders in which thought control is an issue. With an item-method DF paradigm in an auditory form, the underlying neurocognitive processes that support auditory DF were investigated.

Suppress to Forget: The Effect of a Mindfulness-Based Strategy during an Emotional Item-Directed Forgetting Paradigm.

Forgetting is a common phenomenon in everyday life. Although it often has negative connotations, forgetting is an important adaptive mechanism to avoid loading the memory storage with irrelevant information. A very important aspect of forgetting is its interaction with emotion.

Impact of repetitive theta burst stimulation on motor cortex excitability.

Theta burst stimulation (TBS) alters cortical excitability in inhibitory or facilitatory directions depending on the pattern of stimulation used. Although continuous TBS (cTBS) decreases motor cortex excitability, intermittent TBS (iTBS) increases excitability by introducing an 8-second stimulation interval after 2 seconds of TBS. The after-effects induced by TBS last from 30 minutes up to 1 hour.

Simply longer is not better: reversal of theta burst after-effect with prolonged stimulation.

From all rTMS protocols at present, the theta burst stimulation (TBS) is considered the most efficient in terms of number of impulses and intensity required during a given stimulation. The aim of this study was to investigate the effects of inhibitory and excitatory TBS protocols on motor cortex excitability when the duration of stimulation was doubled. Fourteen healthy volunteers were tested under four conditions: intermittent theta bust stimulation (iTBS), continuous theta burst stimulation (cTBS), prolonged intermittent theta bust stimulation (ProiTBS) and prolonged continuous theta burst stimulation (ProcTBS).

Electrical estimulation of retinal pigment epithelial cells.

We investigated and characterized the effect of externally applied electric fields (EF) on retinal pigment epithelial (RPE) cells by exposing primary cultures of human RPE cells (hRPE) and those from the ARPE19 immortalized cell line to various strengths of EF (EF-treated cells) or to no EF (control cells) under different conditions including presence or absence of serum and gelatin and following wounding. We evaluated changes in RPE cell behavior in response to EF by using a computer based image capture and analysis system (Metamorph). We found that RPE cells responded to externally applied EFs by preferential orientation perpendicular to the EF vector, directed migration towards the anode, and faster translocation rate than control, untreated cells.
