Spinal cord injury (SCI) results in the development of chronic pain syndromes that can persist indefinitely and cause reductions in quality of life. Treatment of chronic pain after SCI remains extremely challenging; thus, an important research goal is to determine whether early treatments can attenuate the subsequent development of pain conditions. The current study examined the hypothesis that early administration of the microglial-inhibiting drug minocycline could ameliorate the development of pain after SCI. ⋯ Electrophysiological experiments showed that early minocycline administration attenuated the development of chronic hyperresponsiveness of lumbar dorsal horn neurons. Similarly, behavioral assessment showed that minocycline also resulted in increased pain thresholds. These results suggest that inhibition of early neuroimmune events can have a powerful impact on the development of long-term pain phenomena following SCI and support the conclusion that modulation of microglial signaling may provide a new therapeutic strategy for patients suffering from post-SCI pain.

The objective of this study was to summarize the evidence on the accuracy of screening tools for predicting falling risk in community-living older adults. This study was designed as a systematic review. Prospective studies of clinical fall risk prediction tools that provided data on the number of participants who sustained falls during follow-up were included. ⋯ Most tools discriminated poorly between fallers and nonfallers. We found that existing studies are methodologically variable and the results are inconsistent. Insufficient evidence exists that any screening instrument is adequate for predicting falls.
