d be considered. Greater consistency in reporting of dosimetric and LC data is needed to facilitate future pooled analyses. As systemic and biologic therapies evolve, updated analyses will be needed to further assess the necessity, efficacy, and toxicity of SRS and fSRS.

The purpose of the present study was to identify differences in 30-day adverse events, reoperations, readmissions, and mortality for smokers and nonsmokers who undergo operative treatment for a distal radius fracture.

The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was queried for patients who had operatively treated distal radius fractures between 2005 and 2017. Patient characteristics and surgical variables were assessed. CA77.1 Thirty-day outcome data were collected on serious (SAEs) and minor adverse events (MAEs), as well as on infection, return to the operating room, readmission, and mortality. Multivariable logistic analyses with and without propensity-score matching was used to compare outcome measures between the smoker and the nonsmoker cohorts.

In total, 16,158 cases were identified, of whom 3,062 were smokers. After 11 propensity-score matching, the smoking and nonsmoking cohorts had similar demographic characteristics. Based on the multivariable propensity-matched logistic regression, cases in the smoking group had a significantly higher rate of any adverse event (AAE) (odds ratio [OR], 1.75; 95% confidence interval [95% CI], 1.28-2.38), serious adverse event (SAE) (OR, 1.75; 95% CI, 1.22-2.50), and minor adverse event (MAE) (OR, 1.84; 95% CI, 1.04-3.23). Smokers also had higher rates of infection (OR, 1.73; 95% CI, 1.26-2.39), reoperation (OR, 2.07; 95% CI, 1.13-3.78), and readmission (OR, 1.83; 95% CI, 1.20-2.79). There was no difference in 30-day mortality rate.

Smokers who undergo open reduction internal fixation of distal radius fractures had an increased risk of 30-day perioperative adverse events, even with matching and controlling for demographic characteristics and comorbidity status. This information can be used for patient counseling and may be helpful for treatment/management planning.

Prognostic II.

Prognostic II.Gout is present in one third of subjects with CKD but is usually an exclusion criterion in clinical trials investigating the role of uric acid in kidney disease. Bardin et al. report that one third of gouty subjects have hyperechoic medullas by ultrasound (consistent with crystalline deposits) that correlates with increased risk for hypertension and kidney dysfunction and which were not observed in >500 controls. If validated, a "gouty nephropathy" from microcrystalline deposits could be an important, unrecognized cause of CKD.Metabolic acidosis is an early and deleterious complication of chronic kidney disease. Because it is frequently eubicarbonatemic, diagnosis may be difficult. In this issue, Gianella et al. suggest that lower urinary citrate excretion, considered as an homeostatic response to metabolic acidosis, may be helpful for early diagnosis and monitoring of alkali treatment. This study should be an incentive for further assessment of the tubular handling of urinary citrate in CKD patients and determination of the performance of urinary citrate for the diagnosis of eubicarbonatemic metabolic acidosis and monitoring of alkali therapy.Undocumented immigrant patients with kidney disease in the United States are rightfully gaining increased access to scheduled hemodialysis treatments. For health care systems that have transitioned from emergency to more consistent treatments, the impact of this care on patients' livelihood remains unknown. Cervantes and colleagues provide evidence to better understand patients' experiences following transitions to scheduled hemodialysis treatments. These data are invaluable to formulate future implementation strategies that prioritize patients' values and health equity.Early identification of kidney transplant recipients at risk of progressive allograft dysfunction may allow clinicians to provide closer monitoring and more aggressive risk factor modification. In this issue, Raynaud et al. presented a latent class model that clustered kidney transplant recipients into 8 risk categories of post-transplant kidney function loss. This commentary discusses some of the advantages, but also challenges, of the use of latent class analyses, including the clinical applicability of models that are often derived from such approaches.Recent advances in material engineering and gene editing techniques have now made it possible to use sheeted stem cells as distributors of therapeutic factors in clinical practice (e.g., as beating sheets for patients with heart failure). In this issue, Park et al. report the effects of sheets of genome-engineered human umbilical cord-derived mesenchymal stem cells in preserving kidney function after ischemia-reperfusion injury, demonstrating a possible application for acute kidney injury treatment.Activation of cellular antioxidative signaling is expected to be a silver bullet against kidney diseases, and clinical trials of compounds activating the antioxidant transcription factor Nrf2 have revealed their renoprotective effects. However, cardiac events have been observed in some cases with elevated urinary albumin excretion in these trials. Therefore, elucidating the negative effects of Nrf2 activation is essential. Rush and colleagues demonstrated that Nrf2 activation aggravates podocyte injury, a factor related to proteinuria and cardiac failure.Artificial intelligence (AI), and particularly deep learning (DL), are showing great potential in improving pathology diagnostics in many aspects, 1 of which is the segmentation of histology into (diagnostically) relevant compartments. Although most current studies focus on AI and DL in oncologic pathology, an increasing number of studies explore their application to nephropathology, including the study published in this issue of Kidney International by Jayapandian et al.

The accuracy of an initial ED triage decision has been reported to drive the clinical trajectory for ED patients, and, therefore, this assessment is critical to patient safety. The Emergency Severity Index-a 5-point score assigned by a triage nurse and based on disease acuity, patient potential for decompensation, and anticipated resource use-is used both in the United States and internationally. In the US, the Emergency Severity Index is used by up to 94% of the academic medical center emergency departments. In 2020, the Emergency Nurses Association acquired the intellectual property rights to the Emergency Severity Index and is responsible for its maintenance and improvement.

The purpose of this study was to establish a research agenda for the improvement of individual and institutional understanding and use of the Emergency Severity Index.

Modified Delphi process was used with 3 rounds of data collection.

Round 1 yielded 112 issues, which were collapsed into 18 potential research questions in 4 general categories education and training (6 questions), workplace environment (3 questions), emergency care services (7 questions), and special populations (2 questions). These questions were used in round 2 to establish importance. Round 3 yielded a rank ordering of both categories and research questions.

The research priorities as set through the use of this modified Delphi process align well with current gaps in the literature. Research in these areas should be encouraged to improve the understanding of educational, environmental, and process challenges to emergency nurses' triage decisions and accuracy of Emergency Severity Index assignments.

Significant efforts have been made to expand access to medication therapy for opioid use disorder, in particular buprenorphine. As the emergency department is a critical point of access for many patients with opioid use disorder, the initiation of buprenorphine therapy in the emergency department is increasing, and emergency nurses should be familiar with the care of these vulnerable patients. The purpose of this article is to provide a clinical review of opioid use disorder and opioid withdrawal syndrome, medication treatments for opioid use disorder, best clinical practices for ED-initiated buprenorphine therapy, assessment of withdrawal symptoms, discharge considerations, and concerns for special populations. With expanded understanding of opioid use disorder, withdrawal, and available treatments, emergency nurses will be better prepared to deliver and support life-saving treatments for patients and families suffering from this disease. In addition, emergency nurses are well positioned to play an important role in public health advocacy around opioid use disorder, providing critical support for destigmatization and expanded access to safe and efficacious treatments.

To present a surgical technique for the treatment of intradural extramedullary (IDEM) tumors by using endoscopically controlled surgery with open hemilaminectomy technique.

In this study, 20 patients with 22 IDEM tumors were enrolled. An endoscopically controlled surgery with open hemilaminectomy was employed to remove the tumors. Data related to clinical symptoms and medical images before and after surgery were collected for perioperative evaluation and follow-up analysis.

All the tumors in 20 patients were well removed. The clinical symptoms were significantly reduced in all the patients as well. The short-term follow-up data showed that there was no tumor recurrence or spinal deformity.

The endoscopically controlled surgery with open hemilaminectomy technique provided favorable exposure and satisfactory resection to the IDEM tumors. It may be an effective surgical method for treating IDEM tumors. Larger samples and longer follow-up data are needed to verify its long-term effectiveness.

Cystic fibrosis (CF) is a life-limiting genetic condition in which daily therapies to maintain lung health are critical, yet treatment adherence is low. Previous interventions to increase adherence have been largely unsuccessful and this is likely due to a lack of focus on behavioural evidence and theory alongside input from people with CF. This intervention is based on a digital platform that collects and displays objective nebuliser adherence data. The purpose of this paper is to identify the specific components of an intervention to increase and maintain adherence to nebuliser treatments in adults with CF with a focus on reducing effort and treatment burden.

Intervention development was informed by the Behaviour Change Wheel (BCW) and person-based approach (PBA). A multidisciplinary team conducted qualitative research to inform a needs analysis, selected, and refined intervention components and methods of delivery, mapped adherence-related barriers and facilitators, associated intervention functions and behaviour change techniques, and utilised iterative feedback to develop and refine content and processes.
