Recent studies have hypothesized that sterile disc infection with the anaerobic Propionibacterium acnes, recently renamed Cutibacterium acnes, occurs in people with intervertebral disc (IVD) herniation. This study aimed to examine the presence of P. acnes in patients who have Low back pain (LBP) with Modic changes observed in their Magnetic Resonance Imaging (MRI). ⋯ Based on the results, lumbar disc infection with P. acnes may play a significant role in causing Modic changes and the progression of the disease in patients with LBP.

Randomized Controlled Trial
Are endogenous opioid mechanisms involved in the effects of aerobic exercise training on chronic low back pain?: a randomized controlled trial.
Aerobic exercise is believed to be an effective chronic low back pain (CLBP) intervention, although its mechanisms remain largely untested. This study evaluated whether endogenous opioid (EO) mechanisms contributed to the analgesic effects of an aerobic exercise intervention for CLBP. Individuals with CLBP were randomized to a 6-week, 18-session aerobic exercise intervention (n = 38) or usual activity control (n = 44). ⋯ Enhanced EO analgesia (MPQ-Total) was associated with a significantly greater improvement in average chronic pain intensity (P = 0.009). Aerobic exercise training in the absence of other interventions appears effective for CLBP management. Aerobic exercise-related enhancements in endogenous pain inhibition, in part EO-related, likely contribute to these benefits.

Low back pain is a common problem experienced during pregnancy, negatively affecting quality of life. ⋯ The prevalence of low back pain in pregnancy is quite high, and low back pain slightly limits women's activities of daily living.

Low back pain (LBP) is a leading cause of work disability. While absent from work, workers with LBP may receive income support from a system such as workers' compensation or social security. This study examines how and in what contexts income support systems impact the healthcare quality for people with work disability and LBP and their functional capacity. ⋯ They also influence worker functional capacity through the level of participation and financial incentives for employers, measures to prove the validity of the worker's LBP, and certain administrative procedures. These mechanisms are often exclusively context-dependent, and generate differing and unintended outcomes depending on features of the healthcare and income support system, as well as other contextual factors such as socioeconomic status and labour force composition. Research and policy design should consider how income support systems may indirectly influence workers with LBP through the workplace.
