Meta AnalysisPrevalence of smoking in adults with spinal cord stimulators: a systematic review and meta-analysis.
Smoking adversely impacts pain-related outcomes of spinal cord stimulation (SCS). However, the proportion of SCS patients at risk of worse outcomes is limited by an incomplete knowledge of smoking prevalence in this population. Thus, the primary aim of this systematic review is to determine the prevalence of smoking in adults with chronic pain treated with SCS. ⋯ The estimated prevalence of smoking in SCS patients is 2.5 times greater than the general population. Future research should focus on development, testing and deployment of tailored smoking cessation treatments for SCS patients.

Association of the addition of a transversus abdominis plane block to an enhanced recovery program with opioid consumption, postoperative antiemetic use, and discharge time in patients undergoing laparoscopic bariatric surgery: a retrospective study.
Increasing numbers of laparoscopic bariatric surgeries are being performed and enhanced recovery from anesthesia and surgery (ERAS) protocols have been implemented to optimize care for these patients. We evaluated the effects of an anesthesiologist placed preoperative transversus abdominis plane block (TAP) as part of a bariatric surgery ERAS protocol. We hypothesized that an anesthesiologist placed preoperative TAP added to an ERAS protocol following laparoscopic bariatric surgery would reduce total opioid consumption. ⋯ TAP blocks added to a laparoscopic bariatric surgery ERAS protocol were associated with decreased total opioid use, number of antiemetic treatments, and length of stay; however, these changes were not likely clinically important. Our findings do not support widespread clinical benefit of TAP use in ERAS protocols for laparoscopic bariatric surgery.

Clinical TrialLongitudinal neural exposure to local anesthetic and nerve block duration: a retrospective analysis of experimental data from healthy volunteer trials.
Characteristics of a nerve block depend on the distribution of local anesthetic (LA) close to the nerve. The relationship between longitudinal distribution of LA and nerve block characteristics has not been investigated in viv o, but one in vitro study showed decrements in action potential amplitudes with increasing exposure length. We describe the influence of longitudinal neural exposure to LA on nerve block duration adjusted for other likely influential factors. ⋯ Longitudinal neural exposure to LA was significantly associated with nerve block duration. LA dose was the strongest determinant for block duration whereas LA volume had no influence.

Social media for the regional anesthesiologist: can we use it in place of medical journals?
The regional anesthesia community regularly uses social media for advocacy and education. Well-known leaders in the field are willing to share their opinions with colleagues in a public forum. ⋯ Does a lack of online regulation along with a bias towards self-promotion cloud meaningful discussion? In order to avoid the pitfalls of social media, thoughtful communication will help regional anesthesiologists promote their subspecialty. Mindful dialog, promotion of academic journals, and professional etiquette will help maintain a collegial environment.

Levo-corydalmine attenuates microglia activation and neuropathic pain by suppressing ASK1-p38 MAPK/NF-κB signaling pathways in rat spinal cord.
Neuropathic pain is partially refractory to currently available treatments. Although some studies have reported that apoptosis signal-regulating kinase 1 (ASK1) may inhibit chronic pain, the mechanisms underlying this process have not been fully elucidated. ⋯ This study showed that the expression of ASK1 in spinal microglia and ASK1 inhibitor suppressed microglia activation via suppression of p38 MAPK/NF-κB, which ultimately attenuated CCI-induced neuropathic pain. l-CDL also inhibited the ASK1-P38 MAPK/NF-κB axis to attenuate CCI-induced neuropathic pain.
