Authenticity as a Resilience Factor Against CV-19 Threat Among Those With Chronic Pain and Posttraumatic Stress Disorder

Longitudinal changes in depression and anxiety during the COVID-19 pandemic and the impact of COVID-related factors

OBJECTIVE

This study is an investigation of five specific COVID-related stressors and their longitudinal impact on adult depression and anxiety.

METHOD

A total of 592 adults comprised the initial sample at Time 1 in April/May 2020. Follow-ups were conducted about a month later, again in March 2021 and then in March 2022.

RESULTS

Applied linear mixed effect models showed a significant decrease in mean depression scores and anxiety scores from Time 1 to both Times 3 and 4. Neither change over time in anxiety or depression were found to be related to COVID diagnosis, COVID hospitalization, or COVID death. Self-quarantine was related to changes over time in both depression and anxiety, and household quarantine was related to changes over time in depression.

CONCLUSION

While the fallout of the pandemic continues, it is important to understand how these factors may be affecting mental health to better understand where intervention is necessary.

A novel animal model for understanding secondary traumatic stress and visceral pain in male rats

Empathetic relationships and the social transference of behaviours have been shown to occur in humans, and more recently through the development of rodent models, where both fear and pain phenotypes develop in observer animals. Clinically, observing traumatic events can induce 'trauma and stressor-related disorders' as defined in the DSM 5. These disorders are often comorbid with pain and gastrointestinal disturbances; however, our understanding of how gastrointestinal - or visceral - pain can be vicariously transmitted is lacking. Visceral pain originates from the internal organs, and despite its widespread prevalence, remains poorly understood. We established an observation paradigm to assess the impact of witnessing visceral pain. We utilised colorectal distension (CRD) to induce visceral pain behaviours in a stimulus rodent while the observer rodent observed. Twenty four hours post-observation, the observer rodent's visceral sensitivity was assessed using CRD. The observer rodents were found to have significant hyperalgesia as determined by lower visceral pain threshold and higher number of total pain behaviours compared with controls. The behaviours of the observer animals during the observation were found to be correlated with the behaviours of the stimulus animal employed. We found that observer animals had hypoactivity of the hypothalamic-pituitary-adrenal (HPA) axis, highlighted by reduced corticosterone at 90 minutes post-CRD. Using c-Fos immunohistochemistry we showed that observer animals also had increased activation of the anterior cingulate cortex, and decreased activation of the paraventricular nucleus, compared with controls. These results suggest that witnessing another animal in pain produces a behavioural phenotype and impacts the brain-gut axis.

Whole Health Use and Interest Across Veterans With Co-Occurring Chronic Pain and PTSD: An Examination of the 18 VA Medical Center Flagship Sites

Objective

Veterans Healthcare Administration (VHA) conducted a large demonstration project of a holistic Whole Health approach to care in 18 medical centers, which included making complementary and integrative health (CIH) therapies more widely available. This evaluation examines patterns of service use among Veterans with chronic pain, comparing those with and without PTSD.

Methods

We assessed the use of Whole Health services in a cohort of Veterans with co-occurring chronic pain and PTSD (n = 1698; 28.9%), comparing them to Veterans with chronic musculoskeletal pain only (n = 4170; 71.1%). Data was gathered from VA electronic medical records and survey self-report. Whole Health services were divided into Core Whole Health services (e.g., Whole Health coaching) and CIH services (e.g., yoga). Logistic regression was used to determine whether Veterans with co-occurring chronic pain and PTSD utilized more Whole Health services compared to Veterans with chronic pain but without PTSD.

Results

A total of 40.1% of Veterans with chronic pain and PTSD utilized Core Whole Health services and 53.2% utilized CIH therapies, compared to 28.3% and 40.0%, respectively, for Veterans with only chronic pain. Adjusting for demographics and additional comorbidities, Veterans with comorbid chronic pain and PTSD were 1.24 ( 95% CI: 1.12, 1.35, P ≤ .001) times more likely than Veterans with chronic pain only to use Core Whole Health services, and 1.23 ( 95% CI: 1.14, 1.31, P ≤ .001) times more likely to use CIH therapies. Survey results also showed high interest levels in Core Whole Health services and CIH therapies among Veterans who were not already using these services.

Conclusion

Early implementation efforts in VHA led to high rates of use of Core Whole Health and CIH therapy use among Veterans with co-occurring chronic pain and PTSD. Future assessments should examine how well these additional services are meeting the needs of Veterans in both groups.
