The Lack of a Physical Exam During New Patient Telehealth Visits Does Not Impact Plans for Office and Operating Room Procedures

ObjectiveTo understand how the lack of a physical examination during new patient video visits can impact urological surgery planning during the COVID-19 pandemic.MethodsWe retrospectively reviewed 590 consecutive urology patients who underwent new patient video visits from March through May 2020 at a single academic center. Our primary outcome was procedural plan concordance, the proportion of video visit surgical plans that remained the same after the patient was seen in-person, either in clinic or on day of surgery. Median days between video and in-person visits were compared between concordant and discordant cases using the Mann-Whitney U test; P < .05 was significant.ResultsOverall, 195 (33%) were evaluated by new patient video visits and had a procedure scheduled, of which, 186 (95%) had concordant plans after in-person evaluation. Further, 99% of plans for in-office procedures and 91% for operating room procedures were unchanged. Four patients (2.1%) had surgical plans altered after changes in clinical course, two (1%) due to additional imaging, and three (1.5%) based on genitourinary examination findings. Days between video visit and in-person evaluation did not differ significantly in concordant cases (median 37.5 [IQR, 16 - 80.5]) as compared to discordant cases (median 58.0 [IQR, 20 - 224]; P = .12).ConclusionsMost surgical plans developed during new patient video visits remain unchanged after in-person examination. However, changes in clinical course or updated imaging can alter operative plans. Likewise, certain urologic conditions (eg, penile cancer) rely on the genitourinary examination to dictate surgical approach

Arthroscopic Onlay Articular Margin Biceps Tenodesis for Long Head of the Biceps Tendon Pathology

The long head of the biceps (LHB) tendon is a common source of shoulder pain. LHB tendon pathology typically occurs with concomitant rotator cuff or labrum injuries but can occasionally occur in isolation as biceps tendinopathy or rupture. Tenodesis has been increasingly used to treat LHB tendon pathology, and numerous techniques have been developed that vary in approach, fixation construct, and fixation location. In this Technical Note, we describe an arthroscopic onlay articular margin biceps tenodesis with suture anchors. This technique has several advantages, namely intra-articular visualization of the tenodesis, strong fixation to high density bone of the articular margin, and most importantly, preservation of the anatomic length–tension relationship

Emerging Technologies in the Treatment of Adult Spinal Deformity

Outcomes for adult spinal deformity continue to improve as new technologies become integrated into clinical practice. Machine learning, robot-guided spinal surgery, and patient-specific rods are tools that are being used to improve preoperative planning and patient satisfaction. Machine learning can be used to predict complications, readmissions, and generate postoperative radiographs which can be shown to patients to guide discussions about surgery. Robot-guided spinal surgery is a rapidly growing field showing signs of greater accuracy in screw placement during surgery. Patient-specific rods offer improved outcomes through higher correction rates and decreased rates of rod breakage while decreasing operative time. The objective of this review is to evaluate trends in the literature about machine learning, robot-guided spinal surgery, and patient-specific rods in the treatment of adult spinal deformity

Alisertib (MLN8237), an Oral Selective Inhibitor of Aurora Kinase a, Has Clinical Activity and Restores GATA1 Expression in Patients with Myelofibrosis

Abstract Background: The selective AURKA inhibitor alisertib (MLN8237) exhibits disease modifying activity in murine models of myelofibrosis by eradicating atypical megakaryocytes resulting in reduction of marrow fibrosis (Nat Med 2015). Here, we present long term follow-up results from the investigator initiated pilot study of alisertib in patients with myelofibrosis (clinical trials.gov Identifier NCT 02530619). Methods: 24 patients with DIPSS intermediate 1, intermediate-2, or high risk myelofibrosis who were in need of therapy, refractory/intolerant or unlikely to respond to JAK inhibitors with neutrophil count ≥ 1 x109/L, and platelet count ≥ 50 x109/L, received alisertib (provided by Millennium Pharmaceuticals Inc) at a dose of 50 mg twice daily for one week every 21 days. Toxicity assessment was performed by the standard common terminology criteria (Version 4.0). Response was assessed by the international working group for myelofibrosis research and treatment (IWGMRT) criteria. Correlative studies included assessments of JAK2V617F, CALR, and MPL mutant allele burden, degree of fibrosis and GATA1 expression in bone marrow samples obtained pre and post therapy. Results: We enrolled 17 patients with primary myelofibrosis, 4 with post essential thrombocythemia myelofibrosis and 3 with post polycythemia vera myelofibrosis. Median age was 72 years with 66% males. 79% of patients were DIPSS intermediate risk, and the remainder were high risk with 15 patients (62.5%) having received prior JAK inhibitor therapy. Driver mutational status was as follows; 58% JAK2V617F, 29% CALR, and 13% MPL mutated. At study entry, 54% of patients demonstrated palpable splenomegaly ≥ 5 cm below the left costal margin, 54% were transfusion dependent with all patients experiencing constitutional symptoms. At the time of data cut-off, patients received a median of 7.5 cycles (range; 1-29 cycles) of therapy. The 7 patients presently on study have received a median of 23 cycles (range; 8-29 cycles). Reasons for treatment discontinuation included progressive disease/lack of response in 11 (65%) patients, toxicity in 4 (24%) patients and refusal of further therapy in 2 (11%) patients.Safety and Efficacy assessments The most common treatment-emergent grade 3/4 adverse events included neutropenia (42%), thrombocytopenia (29%) and anemia (21%), with 4% each experiencing neutropenic fever, diarrhea, vertigo, elevated creatinine and elevated alanine aminotransferase. 22 patients were considered for response evaluation with 4 of 14 patients (29%) with palpable splenomegaly ≥ 5 cm achieving a spleen response, 1 of 13 patients (8%) becoming transfusion independent, and 5 of 22 patients (23%) experiencing symptom response with ≥ 50% reduction in the MPN-SAF total symptom score. However, when response assessment was restricted to 13 patients who had received a minimum of 5 cycles of therapy, spleen responses were observed in 4 of 7 (57%) patients, 1 of 5 (20%) achieved transfusion independence and 5 of 13 (38%) achieved symptom response. All patients presenting with leukocytosis (n=4) and thrombocytosis (n=2) had resolution with therapy. Of the 7 patients presently on study, four patients continue to demonstrate symptom response, two patients with both spleen and symptom response, and another patient with sustained anemia response. Correlative assessments We compared the intensity of staining of GATA1, a factor that is required for maturation, in sequential bone marrow biopsies from six patients at baseline and after a minimum of five cycles and observed a striking increase in the numbers of GATA1-positive megakaryocytes in five of six cases (Figure 1a). In addition, we observed a one grade reduction in marrow fibrosis in 4 of 6 paired samples (Figure 1b). This reduction in fibrosis was accompanied by sustained responses to the drug. Finally, we compared JAK2, MPL or CALR mutant allele burden in eight paired baseline and cycle 5 or 6 samples and observed decreases in 4 of 8 patients (Figure 1c). Conclusions: Alisertib is safe and well tolerated in patients with myelofibrosis with prolonged administration up to 1.7 years. In addition to providing clinical benefit, alisertib restored normal morphology and GATA1 expression in atypical megakaryocytes and reduced marrow fibrosis and mutant allele burdens. These findings demonstrate that AURKA inhibition should be further explored as a therapeutic option in myelofibrosis. Figure 1. Figure 1. Disclosures Swords: AbbVie: Employment.

Aurora Kinase A Inhibition Provides Clinical Benefit, Normalizes Megakaryocytes, and Reduces Bone Marrow Fibrosis in Patients with Myelofibrosis: A Phase I Trial

Myelofibrosis is characterized by bone marrow fibrosis, atypical megakaryocytes, splenomegaly, constitutional symptoms, thrombotic and hemorrhagic complications, and a risk of evolution to acute leukemia. The JAK kinase inhibitor ruxolitinib provides therapeutic benefit, but the effects are limited. The purpose of this study was to determine whether targeting AURKA, which has been shown to increase maturation of atypical megakaryocytes, has potential benefit for patients with myelofibrosis. Twenty-four patients with myelofibrosis were enrolled in a phase I study at three centers. The objective of the study was to evaluate the safety and preliminary efficacy of alisertib. Correlative studies involved assessment of the effect of alisertib on the megakaryocyte lineage, allele burden, and fibrosis. In addition to being well tolerated, alisertib reduced splenomegaly and symptom burden in 29% and 32% of patients, respectively, despite not consistently reducing the degree of inflammatory cytokines. Moreover, alisertib normalized megakaryocytes and reduced fibrosis in 5 of 7 patients for whom sequential marrows were available. Alisertib also decreased the mutant allele burden in a subset of patients. Given the limitations of ruxolitinib, novel therapies are needed for myelofibrosis. In this study, alisertib provided clinical benefit and exhibited the expected on-target effect on the megakaryocyte lineage, resulting in normalization of these cells and reduced fibrosis in the majority of patients for which sequential marrows were available. Thus, AURKA inhibition should be further developed as a therapeutic option in myelofibrosis.
