Abstract

To the Editor: Acute kidney injury (AKI) is a lesser-known complication of hip fracture that may come about owing to decreased kidney perfusion and heightened inflammation from trauma, pain, bleeding, and fasting. Approximately 15%-20% of patients undergoing surgery for a hip fracture develop AKI, with 0.5%-1.8% receiving dialysis. [...]

Abstract

© 2020 Elsevier Ltd Background: Observational studies have suggested that accelerated surgery is associated with improved outcomes in patients with a hip fracture. The HIP ATTACK trial assessed whether accelerated surgery could reduce mortality and major complications. Methods: HIP ATTACK was an international, randomised, controlled trial done at 69 hospitals in 17 countries. Patients with a hip fracture that required surgery and were aged 45 years or older were eligible. Research personnel randomly assigned patients (1:1) through a central computerised randomisation system using randomly varying block sizes to either accelerated surgery (goal of surgery within 6 h of diagnosis) or standard care. The coprimary outcomes were mortality and a composite of major complications (ie, mortality and non-fatal myocardial infarction, stroke, venous thromboembolism, sepsis, pneumonia, life-threatening bleeding, and major bleeding) at 90 days after randomisation. Patients, health-care providers, and study staff were aware of treatment assignment, but outcome adjudicators were masked to treatment allocation. Patients were analysed according to the intention-to-treat principle. This study is registered at ClinicalTrials.gov (NCT02027896). Findings: Between March 14, 2014, and May 24, 2019, 27 701 patients were screened, of whom 7780 were eligible. 2970 of these were enrolled and randomly assigned to receive accelerated surgery (n=1487) or standard care (n=1483). The median time from hip fracture diagnosis to surgery was 6 h (IQR 4–9) in the accelerated-surgery group and 24 h (10–42) in the standard-care group (p

Abstract

David Sackett, the father of evidence-based medicine (EBM), died recently - exactly 25 years after the term EBM was coined. This coincidence calls for reflection on the historical significance of EBM and on Sackett's role. The rise of EBM appears to be part of a much broader development: a shift from 'trust in the experts' to 'trust in numbers' that occurred under the pressures of the socio-political conditions of the late twentieth century. Insight into this historical context contributes to a better understanding of the emergence, merits and weaknesses of EBM and of the current tensions between medical professionals and insurers. However, context alone does not explain everything; the course of history - and the history of EBM - is partly determined by special men and women, individual reformers who manage to set things and people in motion. David Sackett is an excellent example of this.

Abstract

Placebo has been reported to exert beneficial effects in patients regarding the treatment of pain. Human functional neuroimaging technology can study the intact human brain to elucidate its functional neuroanatomy and the neurobiological mechanism of the placebo effect. Blood flow measurement using functional magnetic resonance imaging and positron emission tomography (PET) has revealed that analgesia is related to decreased neural activities in pain-modulatory brain regions, such as the rostral anterior cingulate cortex (rACC), insula, thalamus, and brainstem including periaqueductal gray (PAG) and ventromedial medulla. The endogenous opioid system and its activation of mu-opioid receptors are thought to mediate the observed effects of placebo. The mu-opioid receptor-selective radiotracer-labeled PET studies show that the placebo effects are accompanied by reduction in activation of opioid neural transmission in pain-sensitive brain regions, including rACC, prefrontal cortex, insula, thalamus, amygdala, nucleus accumbens (NAC) and PAG. Further PET studies with dopamine D2/D3 receptor-labeling radiotracer demonstrate that basal ganglia including NAC are related to placebo analgesic responses. NAC dopamine release induced by placebo analgesia is related to expectation of analgesia. These data indicate that the aforementioned brain regions and neurotransmitters such as endogenous opioid and dopamine systems contribute to placebo analgesia.

Abstract

Importance: Matched placebo interventions are complex and resource intensive. Recent evidence suggests matched placebos may not always be necessary. Previous studies have predominantly evaluated potential bias of nonmatched placebos (ie, differing on dose, frequency of administration, or formulation) in pain and mental health, but to date no systematic examination has been conducted in infectious disease., Objective: To test for differences between nonmatched and matched placebo arms with respect to clinical outcome measures across multiple therapeutics for COVID-19., Design, Setting, and Participants: In a comparative effectiveness research study, a post hoc analysis was conducted of data on individual patients enrolled in a large, multiarm, platform randomized clinical trial in symptomatic adult outpatients with COVID-19 between January 15, 2021, to September 28, 2023, in which the outcomes of both matched and nonmatched placebo groups were reported. Bayesian and frequentist covariate-adjusted techniques were compared with 7 intervention-placebo pairs., Exposures: Seven matched and nonmatched placebo pairs (for a total of 7 comparisons) were evaluated throughout the primary platform trial. Comparisons were made between treatment and its associated matched (concurrent) placebo, as well as with nonmatched placebo (alone and in combination) assessed at a similar time point., Main Outcomes and Measures: Outcomes assessed included hospitalizations, EuroQol 5-Dimension 5-level scores, and PROMIS Global-10 scores., Results: A total of 7 intervention-control pairs (N = 2684) were assessed, including 1620 (60.4%) women, with mean (SD) age, 47 (15.2) years; the most common comorbidities were obesity (41.9%) and hypertension (37.9%). In a meta-analysis with decoupled SEs, accounting for overlapping placebo patients, the overall odds ratio (OR) of nonmatched compared with matched placebo was 1.01 (95% credible interval, 0.77-1.32), with posterior probability of equivalence, defined as 0.8 ≤ OR ≤ 1.2 (a deviation from perfect equivalence ie, OR = 1, by no more than 0.2) of 85.4%, implying no significant difference. Unadjusted analysis of the event rate difference between all nonmatched and matched placebo groups did not identify any notable differences across all 7 treatment-placebo combinations assessed. Similar analysis that was conducted for patient-reported quality of life outcomes did not yield statistically significant differences., Conclusions and Relevance: In this post hoc study of a randomized clinical platform trial, pooling matched and nonmatched placebo patient data did not lead to inconsistencies in treatment effect estimation for any of the investigational drugs. These findings may have significant implications for future platform trials, as the use of nonmatched placebo may improve statistical power, or reduce barriers to placebo implementation.
