Management of functional bowel disorders. The better knowledge of irritable bowel syndrome (IBS) and functional bloating pathogenic mechanisms led to an increase of the possible therapeutic options, ...which are somewhat different, in IBS, between IBS-D and IBS-C Besides routine options (antispasmodics, alverine, laxatives, loperamide), low-dose antidepressants and non-pharmaceutical options are now recognized as validated and effective therapeutic choices. In addition, dietary advices (particularly indication of a low FODMAPs diet) and treatments acting on gut microbiota (probiotics, antibiotics) are more and more discussed and indicated. In functional bloating, treatment remains empirical. Dietary modifications, simeticone, prokinetics, low-dose antidepressants and microbiome modulation can be proposed.
Background
Virtual reality hypnosis (VRH) is a promising tool to reduce pain. However, the benefits of VRH on pain perception and on the physiological expression of pain require further ...investigation.
Objective
In this study, we characterized the effects of VRH on the heat pain threshold among adult healthy volunteers while monitoring several physiological and autonomic functions.
Methods
Sixty healthy volunteers were prospectively included to receive nociceptive stimulations. The first set of thermal stimuli consisted of 20 stimulations at 60°C (duration 500 milliseconds) to trigger contact heat evoked potentials (CHEPs). The second set of thermal stimuli consisted of ramps (1°C/second) to determine the heat pain threshold of the participants. Electrocardiogram, skin conductance responses, respiration rate, as well as the analgesia nociception index were also recorded throughout the experiment.
Results
Data from 58 participants were analyzed. There was a small but significant increase in pain threshold in VRH (50.19°C, SD 1.98°C) compared to that in the control condition (mean 49.45°C, SD 1.87; P<.001, Wilcoxon matched-pairs signed-rank test; Cohen d=0.38). No significant effect of VRH on CHEPs and heart rate variability parameters was observed (all P>0.5; n=22 and n=52, respectively). During VRH, participants exhibited a clear reduction in their autonomic sympathetic tone, as shown by the lower number of nonspecific skin conductance peak responses (P<.001, two-way analysis of variance; n=39) and by an increase in the analgesia nociception index (P<.001, paired t-test; n=40).
Conclusions
The results obtained in this study support the idea that VRH administration is effective at increasing heat pain thresholds and impacts autonomic functions among healthy volunteers. As a nonpharmacological intervention, VRH has beneficial action on acute experimental heat pain. This beneficial action will need to be evaluated for the treatment of other types of pain, including chronic pain.
Acquired mutations in the UBA1 gene were recently identified in patients with severe adult-onset auto-inflammatory syndrome called VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic). ...However, the precise physiological and clinical impact of these mutations remains poorly defined. Here we study a unique prospective cohort of VEXAS patients. We show that monocytes from VEXAS are quantitatively and qualitatively impaired and display features of exhaustion with aberrant expression of chemokine receptors. In peripheral blood from VEXAS patients, we identify an increase in circulating levels of many proinflammatory cytokines, including IL-1β and IL-18 which reflect inflammasome activation and markers of myeloid cells dysregulation. Gene expression analysis of whole blood confirms these findings and also reveals a significant enrichment of TNF-α and NFκB signaling pathways that can mediate cell death and inflammation. This study suggests that the control of the nflammasome activation and inflammatory cell death could be therapeutic targets in VEXAS syndrome.
Migrants, and particularly asylum seekers, are at increased risk of psychiatric disorders in comparison with natives. At the same time, inequalities in access to mental health care are observed.
In ...order to evaluate whether the Parisian public psychiatric system is optimally structured to meet the needs of this population, we examined data on mental health and service use considering three different levels: the global system treatment level, a psychiatric reception center, and mobile teams specializing in access to psychiatric care for asylum seekers.
We found higher treatment rates among migrants than among natives (
< 0.001) but inequalities in pathways to care: more mandatory admissions (OR = 1.36, 95% CI: 1.02-1.80) and fewer specialized consultations (OR = 0.56, 95% CI: 0.38-0.81). We observed a mismatch between increased need and provision of care among migrants without stable housing or seeking asylum.
Inequalities in the provision of care for migrants are observed in the Parisian public psychiatric system, particularly for those experiencing poor social and economic conditions. There is a need to facilitate access to mental health care and develop more tailored interventions to reduce discontinuity of care.
