Abstract
INTRODUCTION Many patients referred for suspicion of myelodysplastic neoplasm (MDS) are subjected to unnecessary discomfort from bone marrow aspiration, due to the low disease prevalence in this population. Flow cytometric analysis of peripheral blood neutrophil myeloperoxidase expression could rule out MDS with sensitivity and negative predictive value estimates close to 100%, ultimately obviating the need for bone marrow aspiration in up to 35% of patients. However, the generalisability of these findings is uncertain due to the limited sample size, the enrolment of patients at a single study site, and the reliability issues associated with laboratory-developed tests and varying levels of operator experience. This study aims to validate the accuracy attributes of peripheral blood neutrophil myeloperoxidase expression quantified by flow cytometric analysis in an independent multicentre sample. METHODS AND ANALYSIS The MPO-MDS-Valid project is a cross-sectional diagnostic accuracy study comparing an index test to a reference standard. Consecutive adult patients referred for suspicion of MDS are being recruited at seven university hospitals and one cancer centre in France. At each site, flow cytometric analysis of peripheral blood samples is performed by operators who are blinded to the reference diagnosis. A central adjudication committee whose members are unaware of the index test results will determine the reference diagnosis of MDS, based on cytomorphological evaluation of bone marrow performed in duplicate by experienced hematopathologists. The target sample size is 400 patients and the anticipated study recruitment completion date is 31 December 2025. ETHICS AND DISSEMINATION An institutional review board (Comité de Protection des Personnes Nord-Ouest III, Caen, France) approved the protocol, prior to the start of the study. Participants are recruited using an opt-out approach. Efforts will be made to publish the primary results within 6 months after study completion. TRIAL REGISTRATION NUMBER NCT05175469.

Abstract
BACKGROUND Bone marrow (BM) biopsy is the most common diagnostic procedure in hematology. Bleeding is an expected complication, and its risk is assumed to be increased in patients on anticoagulants. However, the effect of anticoagulation on BM biopsy safety is unclear and guidelines are lacking robust data in this regard. As such, physicians use their clinical judgement to guide periprocedural management of anticoagulation. OBJECTIVE To provide the best available evidence regarding management of anticoagulation in patients who need BM biopsy. METHODS We reviewed and summarized available guidelines directing management of periprocedural anticoagulation for BM biopsy, and share our experience and practices with BM biopsy at our institution. RESULTS The incidence of significant hemorrhage after BM biopsy is very low (0.007-1.1%). BM biopsy is classified as having a low to moderate bleeding risk. Interrupting anticoagulation is not consistently recommended. Strategies exist to minimize bleeding risk for anticoagulated patients. Patients with myeloproliferative neoplasms can develop an acquired von Willebrand syndrome which increases their risk for bleeding and therefore require extra vigilance to ensure appropriate hemostasis. CONCLUSION Withholding anticoagulation prior to BM biopsy is not routinely recommended. Instead, assessment and optimization of bleeding risk factors should be done on a patient by patient basis.

Abstract
: Background: At our institution, RNs have performed bone marrow aspiration and biopsy procedures for more than 10 years. A recent review of our institutional policies and practices regarding RN-performed bone marrow procedures was intended to ensure that we were using a safe and evidence-based approach and prompted this program evaluation. METHODS We conducted a literature search and review of our institutional policies and practices regarding RN-performed bone marrow procedures. All elements of our clinical practice were reviewed and evaluated, including outcomes. RESULTS Between 2010 and 2017, the RN team completed a total of 10,867 bone marrow procedures in our hospital-based ambulatory infusion center. The team included 15 nurses who completed up to eight patient procedures each weekday. Patient satisfaction rates were consistently high and complication rates were very low: less than 1% of all patients experienced postprocedure bleeding, and less than 2% required urgent medical care within 24 hours of the procedure. In an analysis of bone marrow procedures performed between 2016 and 2017, the quality of bone marrow samples obtained by the RN team remained high, consistently meeting or exceeding our 95% clinical adequacy goal. CONCLUSIONS There is limited evidence in the literature supporting the practice of RN-performed bone marrow procedures. Our review revealed a robust program with excellent clinical and diagnostic outcomes that can be emulated by other institutions interested in pursuing RN-performed bone marrow procedures.

Abstract
Clinicians routinely perform bone marrow aspiration and biopsy (BMAB) to diagnose cancer and evaluate disease status; however, few studies address pain and distress with BMAB. A prospective descriptive-correlational design examined patients' (N = 152) ratings of pain intensity (numeric rating scale, 0-10) and distress (distress thermometer) at baseline and 5 min and 1 hr postprocedure. Data were analyzed using descriptive statistics, chi-square, and linear regression models. Mean postprocedure pain intensity at 5 min was moderate, 5.56 (SD = 3.03), and opioid use was associated with decreased pain at 1 hr (p < .001). Preprocedure administration of anxiolytics had no significant effect on distress reduction (p = .88). Being female, first-time biopsy, and increased preprocedure pain were significant predictors of postprocedure distress (p < .001). Treating anxiety alone may not be sufficient to lessen pain and distress. Individualized plans of care should be based on patient risk and response to procedure.

Abstract
Bone biopsy is an invasive clinical procedure, where a bone sample is recovered for analysis during the diagnosis of a medical condition. When the architecture of the bone tissue is required to be preserved, a core-needle biopsy is taken. Although this procedure is performed while the patient is under local anaesthesia, the patient can still experience significant discomfort. Additionally, large haematoma can be induced in the soft tissue surrounding the biopsy site due to the large axial and rotational forces, which are applied through the needle to penetrate bone. It is well documented that power ultrasonic surgical devices offer the advantages of low cutting force, high accuracy, and preservation of soft tissues. This paper reports a study of the design, analysis, and test of two novel power ultrasonic needles for bone biopsy that operate using different configurations to penetrate bone. The first utilizes micrometric vibrations generated at the distil tip of a full-wavelength resonant ultrasonic device, while the second utilizes an ultrasonic-sonic approach, where vibrational energy generated by a resonant ultrasonic horn is transferred to a needle via the chaotic motion of a free-mass. It is shown that the dynamic behavior of the devices identified through experimental techniques closely match the behavior calculated through numerical and finite-element analysis methods, demonstrating that they are effective design tools for these devices. Both devices were able to recover trabecular bone from the metaphysis of an ovine femur, and the biopsy samples were found to be comparable to a sample extracted using a conventional biopsy needle. Furthermore, the resonant needle device was also able to extract a cortical bone sample from the central diaphysis, which is the strongest part of the bone, and the biopsy was found to be superior to the sample recovered by a conventional bone biopsy needle.
