This study aimed to identify patterns of opioid dispensing in Australian workers with low back pain (LBP) and determine the association of dispensing patterns with wage replacement duration. Australian workers' compensation claimants with LBP and at least 1 day of wage replacement were included. We used group-based trajectory modelling to identify opioid dispensing patterns over a two-and-a-half-year period from reported LBP onset and quantile regression to compare wage replacement duration between each dispensing pattern group. ⋯ In addition, moderate-volume and high-volume long-term dispensing groups had significantly longer wage replacement duration compared with the short-term dispensing group (median [weeks]: 126.9, 126.0, and 30.7, respectively). Without controlling for pain severity, these results offer limited evidence that opioids lead to longer wage replacement duration. Further research controlling for pain severity, psychosocial factors, and recovery expectations is required to confirm whether the relationship between opioid dispensing pattern and wage replacement duration is causal in nature.

Poor sleep quality has a negative effect on pain among older adults. During the coronavirus disease 2019 (COVID-19) state of emergency, lifestyle changes can cause psychologic stressors and lead to poor sleep quality. ⋯ During the COVID-19 state of emergency, poor sleep quality was associated with worsening low back or knee pain. This may indicate the need to pay attention to poor sleep quality to prevent the exacerbation of pain among old-old adults.

There is moderate quality evidence that exercise can help to prevent future low back pain (LBP). This study aimed to explore patient needs and preferences for exercise programs to prevent LBP and the outcomes of these programs that would be most important to a patient. Researchers conducted 26 semistructured interviews with people with LBP. ⋯ Clinicians should discuss with patients the transition from a focus on treatment to the prevention of LBP. This provides greater opportunity to adjust goals and expectations and provide relevant education. Balancing the need for individualised care against affordability presents an ongoing challenge.

It is suggested that non-specific low back pain (LBP) can be related to nerve ingrowth along granulation tissue in disc fissures, extending into the outer layers of the annulus fibrosus. Present study aimed to investigate if machine-learning modelling of magnetic resonance imaging (MRI) data can classify such fissures as well as pain, provoked by discography, with plausible accuracy and precision. ⋯ The present study showed that machine-learning modelling based on MRI can classify outer annular fissures with very high diagnostic accuracy and, hence, enable individualized diagnostics. However, the model only demonstrated moderate diagnostic accuracy regarding pain that could be assigned to either a non-sufficient model or the used pain reference.

Chronic low back pain (CLBP) is one of the leading causes of pain and disability in adults in the United States and disproportionately burdens non-Hispanic Black (NHB) individuals and females. Approximately 90% of CLBP cases are of unknown cause, and it is imperative that potential causes be explored. It has been reported that diet quality can influence pain state via diet-induced inflammation. ⋯ Further research is needed to determine whether dietary interventions that reduce inflammation improve CLBP outcomes and whether these interventions may be differentially-beneficial based on sex. PERSPECTIVE: This article highlights the impact of diet-induced inflammation in a community-based sample as a whole, as well as stratified in various sociodemographic groups. This work expands our understanding of the influence of diet on pain experience and suggests that modifications to diet may be efficacious treatments for reducing chronic pain.
