Randomized Controlled Trial Multicenter Study
The Effect of Perioperative Dexamethasone on Postoperative Complications after Pancreaticoduodenectomy: A Multicenter Randomized Controlled Trial.
To evaluate the effect of perioperative dexamethasone on postoperative complications after pancreaticoduodenectomy. ⋯ Perioperative dexamethasone did not significantly reduce postoperative complications within 30 days after pancreaticoduodenectomy.

Meta Analysis
The effect of unpredictability on the perception of pain: a systematic review and meta-analysis.
Despite being widely assumed, the worsening impact of unpredictability on pain perception remains unclear because of conflicting empirical evidence, and a lack of systematic integration of past research findings. To fill this gap, we conducted a systematic review and meta-analysis focusing on the effect of unpredictability on pain perception. We also conducted meta-regression analyses to examine the moderating effect of several moderators associated with pain and unpredictability: stimulus duration, calibrated stimulus pain intensity, pain intensity expectation, controllability, anticipation delay, state and trait negative affectivity, sex/gender and age of the participants, type of unpredictability (intensity, onset, duration, location), and method of pain induction (thermal, electrical, mechanical pressure, mechanical distention). ⋯ However, several significant moderators were found, ie, targeted stimulus pain intensity, expected pain intensity, and state negative affectivity. Trait negative affectivity and uncontrollability showed no significant effect, presumably because of the low number of included studies. Thus, further investigation is necessary to clearly determine their role in unpredictable pain perception.

Given the rapid growth of nonoperating room anesthesia (NORA) in recent years, it is essential to review its unique challenges as well as strategies for patient selection and care optimization. ⋯ Considering the unique challenges of NORA settings, meticulous patient selection, risk stratification, and preoperative optimization are crucial. Embracing data-driven strategies and leveraging technological innovations (such as artificial intelligence) is imperative to refine quality control methods in targeted areas. Collaborative efforts led by anesthesia providers will ensure personalized, well tolerated, and improved patient outcomes across all phases of NORA care.

Observational Study
Does celecoxib prescription for pain management impact post-tonsillectomy hemorrhage requiring surgery? A retrospective observational cohort study.
Adenotonsillectomy and tonsillectomy (referred to as tonsillectomy hereafter) are common pediatric surgeries. Postoperative complications include hemorrhage requiring surgery (2 to 3% of cases) and pain. Although nonsteroidal anti-inflammatory drugs are commonly administered for postsurgical pain, controversy exists regarding bleeding risk with cyclooxygenase-1 inhibition and associated platelet dysfunction. Preliminary evidence suggests selective cyclooxygenase-2 inhibitors, for example celecoxib, effectively manage pain without adverse events including bleeding. Given the paucity of data for routine celecoxib use after tonsillectomy, this study was designed to investigate the association between postoperative celecoxib prescription and post-tonsillectomy hemorrhage requiring surgery using chart-review data from the Children's Hospital of Eastern Ontario. ⋯ Celecoxib does not significantly increase the odds of post-tonsillectomy hemorrhage requiring surgery, after adjusting for covariates. This large pediatric cohort study of celecoxib administered after tonsillectomy provides compelling evidence for safety but requires confirmation with a multisite randomized controlled trial.

Pain anticipation during conditions of uncertainty can unveil intrinsic biases, and understanding these biases can guide pain treatment interventions. This study used machine learning and functional magnetic resonance imaging to predict anticipatory responses in a pain anticipation experiment. One hundred forty-seven participants that included healthy controls (n = 57) and individuals with current and/or past mental health diagnosis (n = 90) received cues indicating upcoming pain stimuli: 2 cues predicted high and low temperatures, while a third cue introduced uncertainty. ⋯ Three distinct response profiles emerged: subjects with a negative bias towards high pain anticipation, those with a positive bias towards low pain anticipation, and individuals whose predictions during uncertainty were unbiased. These profiles remained stable over one year, were consistent across diagnosed psychopathologies, and correlated with cognitive coping styles and underlying insula anatomy. The findings suggest that individualized and stable pain anticipation occurs in uncertain conditions.
