Trajectories and individual differences in pain, emotional distress, and prescription opioid misuse during the COVID-19 pandemic: A one-year longitudinal study.

Recent studies suggest that the COVID-19 pandemic can serve as a unique psychosocial stressor that can negatively impact individuals with chronic pain. Using a large online sample in the U.S., the present study sought to investigate the impact of the pandemic on the trajectories of pain severity and interference, emotional distress (i.e., anxiety and depressive symptoms), and opioid misuse behaviors across one year. Potential moderating effects of socio-demographic factors and individual differences in pain catastrophizing, pain acceptance, and sleep disturbance on outcome trajectories were also examined. Adults with chronic pain were surveyed three times across one year (April/May 2020 [N=1,453]; June/July 2020 [N=878], and May 2021 [N=813]) via Amazon's Mechanical Turk online crowdsourcing platform. Mixed-effects growth models revealed that pain severity and interference, emotional distress, and opioid misuse behaviors did not significantly deteriorate across one year during the pandemic. None of the socio-demographic factors, pain catastrophizing, or sleep disturbance moderated outcome trajectories. However, individuals with higher pain acceptance reported greater improvement in pain severity (p< .008, 95% CI: -.0002, -.00004) and depressive symptoms (p< .001, 95% CI: -.001, -.0004) over time. Our findings suggest that the negative impact of the pandemic on pain, emotional distress, and opioid misuse behaviors is quite small overall. The outcome trajectories were also stable across different socio-demographic factors, as well as individual differences in pain catastrophizing and sleep disturbance. Nevertheless, interventions that target improvement of pain acceptance may help individuals with chronic pain be resilient during the pandemic.

Recurrent pain in school-aged children: a longitudinal study focusing on the relation to academic achievement (manuscript).

Recurrent pain is an increasing public health problem among school-aged children, with potential negative impact on children´s daily lives, such as schoolwork. The overall aim of this study was to investigate whether recurrent pain in school year 6 was associated with poorer academic achievement at the end of elementary school in school year 9. The study was a follow-up study based on data from "The Study of Health in School-Aged Children from Umeå" (SISU). Participants were 1567 children aged 12 to 13 years who attended school year 6. A follow-up was done in school year 9, when the children were 16 years old. The children answered a questionnaire about recurrent pain (headache, stomachache, and backache). Information about academic achievement was collected from school registers. The results showed that having weekly recurrent pain in school year 6 predicted lower final overall grade points in school year 9 compared to children with no recurrent pain. This applied for recurrent headache, stomachache, backache, and multiple pains and for both girls and boys. Recurrent pain did not predict secondary school eligibility, however. Perceived problems with academic achievement and problems with concentration partly mediated the association between recurrent pain and lower final overall grade points. Sleep problems were not associated with academic achievement and were therefore not a mediator. Thus, the results suggest that recurrent pain may predict later impairment of academic achievement and that problems with concentration and children´s perceived achievement in school, but not sleep problems, may partly explain this relationship.

The Individual Placement and Support (IPS) in Pain Trial: A randomized controlled trial of IPS for patients with chronic pain conditions.

Although complex pain conditions require an interdisciplinary approach, employment services are rarely provided in pain centers. Individual Placement and Support (IPS) is an effective approach to increase work participation among patients with severe mental illness, and recent evidence suggests that this method may be successfully repurposed to new target groups.We aimed to investigate the effectiveness of IPS integrated with interdisciplinary treatment as usual (TAU) for patients with chronic pain in a tertiary pain center.

Cardiorenal Risk of Celecoxib compared to Naproxen, or Ibuprofen in Arthritis Patients: Insights from the PRECISION trial.

Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most frequently used drugs both prescribed and over the counter. The long-term cardiovascular safety of NSAIDs in patients with arthritis has engendered controversy. Concerns remain regarding the relative incidence and severity of adverse cardiorenal effects, particularly in arthritis patients with established CV disease, or risk factors for disease as illustrated by the PRECISION trial participants (NCT00346216).

eDOL mHealth App and Web Platform for Self-monitoring and Medical Follow-up of Patients With Chronic Pain: Observational Feasibility Study.

Chronic pain affects approximately 30% of the general population, severely degrades quality of life (especially in older adults) and professional life (inability or reduction in the ability to work and loss of employment), and leads to billions in additional health care costs. Moreover, available painkillers are old, with limited efficacy and can cause significant adverse effects. Thus, there is a need for innovation in the management of chronic pain. Better characterization of patients could help to identify the predictors of successful treatments, and thus, guide physicians in the initial choice of treatment and in the follow-up of their patients. Nevertheless, current assessments of patients with chronic pain provide only fragmentary data on painful daily experiences. Real-life monitoring of subjective and objective markers of chronic pain using mobile health (mHealth) programs can address this issue.

Early Relationships of a Low-Energy Diet With Symptoms of Fibromyalgia.

Previous studies have demonstrated that weight loss has been shown to improve pain in weight-bearing joints, and more recent studies suggest that weight loss may be accompanied by improvements in pain in non-weight-bearing regions. In previous work, we demonstrated that these symptoms improve substantially in patients with obesity undergoing 12 weeks of a very low-energy diet (VLED) restricted to 800 kcal as part of a weight-loss program. Preclinical models also have shown analgesic effects of calorie restriction. The purpose of the current observational study was to determine the time course and trajectory of improvement in pain and other symptoms, especially during the early phase of a VLED intervention, prior to major weight loss.

Disparities in Opioid Prescribing for Long-Term Chronic and Short-Term Acute Pain: Findings from the 2019 National Health Interview Survey.

The CDC cautioned against prescribing opioids for long-term chronic pain because opioid use disorder (OUD) risk was greater compared to short-term use for acute pain. The study objective was to describe rates and characteristics of respondents prescribed opioids for long-term chronic and short-term acute pain. National Health Interview Survey respondents for 2019 aged 18 years and over were examined (n = 31,997). Bivariate and multivariable models demonstrated opioid use for long-term and acute pain relative to sociodemographic characteristics. About 12.3% of US adults took opioids in the last 12 months, and among those with chronic pain who had been prescribed opioids in the last 3 months, over half took opioids every day. The odds of taking opioids for long-term chronic pain decreased with increasing income and increased with advancing age. Opioid prescribing diverged from CDC recommendations. Less affluent older adults may be at increased risk for OUD.

Non-Medical Factors Associated with the Outcome of Treatment of Chronic Non-Malignant Pain: A Cross-Sectional Study.

Chronic pain is a global public health issue with increasing prevalence. Chronic pain causes sleep disorder, reactive anxiety, and depression, impairs the quality of life; it burdens the individual and society as a whole. The aim of this study was to examine non-medical factors related to the outcome of the treatment of chronic non-malignant pain.

Trajectories of prescription opioid dose and risk of opioid-related adverse events among older Medicare beneficiaries in the United States: A nested case-control study.

Despite the rising number of older adults with medical encounters for opioid misuse, dependence, and poisoning, little is known about patterns of prescription opioid dose and their association with risk for opioid-related adverse events (ORAEs) in older patients. The study aims to compare trajectories of prescribed opioid doses in 6 months preceding an incident ORAE for cases and a matched control group of older patients with chronic noncancer pain (CNCP).
