Background: The preoperative assessment of cartilage lesions is critical to surgical planning and decision making. The accurate radiographic determination of acetabular cartilage damage has remained elusive for modern imaging modalities, including magnetic resonance imaging (MRI) and magnetic resonance arthrography (MRA). While risk factors have been individually described, no multivariable system exists for predicting high-grade cartilage damage. Purpose: To determine the preoperative predictors of grade 3 to 4 acetabular labrum articular disruption (ALAD) lesions. Study Design: Case-control study; Level of evidence, 3. Cohort study (diagnosis); Level of evidence, 1. Methods: Retrievable radiographs were reviewed from primary hip arthroscopic procedures performed at 2 high-volume institutions between December 2007 and April 2017. The predictive value of demographic and radiographic factors for the intraoperative documentation of ALAD grade 3 to 4 damage was analyzed and entered into a multivariable model, and a statistically guided scoring system for the damage risk was created using the Akaike information criterion. The scoring system was then prospectively validated on 167 patients who underwent primary hip arthroscopy between April 2017 and February 2018. Results: A total of 652 primary hip arthroscopic procedures in 614 patients (390 female, 224 male; mean age, 33.2 ± 12.5 years; mean body mass index, 26.9 ± 5.5 kg/m2) from 2007 to 2017 were analyzed. Male sex (odds ratio [OR], 3.11; P < .01), age ≥35 years (OR, 1.96; P < .01), cam morphology (alpha angle >55°) (OR, 2.96; P < .01), and Tönnis grade 1 to 2 (grade 1: OR, 4.14; P < .01, and grade 2: OR, 9.29; P < .01) were univariate risk factors for intraoperatively documented high-grade damage. A multivariable scoring system, the Rapidly Assessed Predictor of Intraoperative Damage (RAPID) score (0-5 points), was generated based on sex, Tönnis grade, and cam morphology. Patients with increasing RAPID scores had an increasing risk of damage, with a 10.5% risk for those with 0 points and an 88.0% risk for those with 5 points ( P < .01). The area under the curve was 0.75 for the study group and 0.76 for the validation group ( P = .94). Conclusion: While preoperative MRI has diagnostic value for hip arthroscopic surgery, the RAPID score provides added benefit as a readily employable, in-clinic system for predicting high-grade cartilage damage. The discriminatory value of the RAPID score compares favorably with previous MRI and MRA studies. This information will help the clinician and patient plan for high-grade damage and identify potential targets for cartilage treatment.

Published: October 2018

Background Personality traits, such as the character traits self-directedness and cooperativeness, might play a role in the risk of developing post-traumatic stress disorder (PTSD) after deployment to a combat zone. However, it is unclear whether these traits are preexisting risk factors or if event-related changes might also be associated with PTSD symptoms over time. Therefore, the current aim was to assess if military deployment is associated with changes in cooperativeness and self-directedness and to study how these traits are related to PTSD symptom trajectories. Methods In a large cohort of military personnel (N = 1007), measurements were performed before, at one and six months, and two and five years after deployment to Afghanistan. Linear mixed-effect models were used to assess the individual change in the traits over time and to study the relation with potential predictors. Results Cooperativeness was found to remain stable, whereas self-directedness was found to slightly decrease over time. This decrease was related to the development of PTSD symptoms over time. Furthermore, lower levels of self-directedness were associated with the symptomatic trajectories of PTSD symptoms. Lower levels of cooperativeness were only associated with the recovered PTSD trajectory. Conclusions So, not only do the findings confirm that lower levels of these character traits are associated with the development of PTSD symptoms, it was also shown that there are differences in the relation between these traits and the course of PTSD symptoms. Studying methods to promote the levels of these character traits might help to improve the resiliency of military personnel.

Abstract
Novel therapies for sickle cell disease (SCD) based on genetically engineered autologous hematopoietic stem and progenitor cells (HSPCs) are critically dependent on a safe and effective strategy for cell procurement. We sought to assess the safety and efficacy of plerixafor when used in transfused patients with SCD for HSC mobilization. Six adult patients with SCD were recruited to receive a single dose of plerixafor, tested at lower than standard (180 µg/kg) and standard (240 µg/kg) doses, followed by CD34+ cell monitoring in peripheral blood and apheresis collection. The procedures were safe and well-tolerated. Mobilization was successful, with higher peripheral CD34+ cell counts in the standard vs the low-dose group. Among our 6 donors, we improved apheresis cell collection results by using a deep collection interface and starting apheresis within 4 hours after plerixafor administration. In the subjects who received a single standard dose of plerixafor and followed the optimized collection protocol, yields of up to 24.5 × 106 CD34+ cells/kg were achieved. Interestingly, the collected CD34+ cells were enriched in immunophenotypically defined long-term HSCs and early progenitors. Thus, we demonstrate that plerixafor can be employed safely in patients with SCD to obtain sufficient HSCs for potential use in gene therapy.
Combination systemic therapies with immune checkpoint inhibitors in pancreatic cancer: overcoming resistance to single‐agent checkpoint blockade

Published: October 2018

AbstractImmune checkpoint inhibitors have demonstrated broad single‐agent antitumor activity and a favorable safety profile that render them attractive agents to combine with other systemic anticancer therapies. Pancreatic cancer has been fairly resistant to monotherapy blockade of programmed cell death protein 1 receptor, programmed death ligand 1, and cytotoxic T‐lymphocyte associated protein 4. However, there is a growing body of preclinical evidence to support the rational combination of checkpoint inhibitors and various systemic therapies in pancreatic cancer. Furthermore, early clinical evidence has begun to support the feasibility and efficacy of checkpoint inhibitor‐based combination therapy in advanced pancreatic cancer. Despite accumulating preclinical and clinical data, there remains several questions as to the optimal dosing and timing of administration of respective agents, toxicity of combination strategies, and mechanisms by which immune resistance to single‐agent checkpoint blockade are overcome. Further development of biomarkers is also important in the advancement of combination systemic therapies incorporating checkpoint blockade in pancreatic cancer. Results from an impressive number of ongoing prospective clinical trials are eagerly anticipated and will seek to validate the viability of combination immuno‐oncology strategies in pancreatic cancer.

Abstract
This paper demonstrates the combined use of X-ray computed tomography (XCT), energy dispersive X-ray spectroscopy (EDX) and X-ray fluorescence (XRF) to evaluate the conservational history of the dentary (lower jaw) of Megalosaurus bucklandii Mantell, 1827, the first scientifically described dinosaur. Previous analysis using XCT revealed that the specimen had undergone at least two phases of repair using two different kinds of plaster, although their composition remained undetermined. Additional chemical analysis using EDX and XRF has allowed the determination of the composition of these unidentified plasters, revealing that they are of similar composition, composed dominantly of ‘plaster of Paris’ mixed with quartz sand and calcite, potentially from the matrix material of the Stonesfield Slate, with the trace presence of chlorine. One of the plasters unusually contains the pigment minium (naturally occurring lead tetroxide; Pb2
2+Pb4+O4) whilst the other seems to have an additional coating of barium hydroxide (Ba(OH)2), indicating that these likely represent two separate stages of repair. The potential of this combined approach for evaluating problematic museum objects for conservation is further discussed as is its usage in cultural heritage today.

Purpose Targeted therapy of ALK in patients with metastatic nonsquamous non–small-cell lung cancer (NSCLC) and ALK rearrangements improves outcomes compared with chemotherapy. This study assessed real-world ALK testing patterns among community practices in the United States in patients with advanced (stage IIIB or IV) NSCLC. Methods Patients age ≥ 18 years with two or more visits within the Flatiron Health electronic health record–derived database after January 2011 and diagnosed with stage IIIB or IV NSCLC through May 2017 were included in this analysis. Logistic regression was used to examine the association between demographic and clinical characteristics and testing for ALK rearrangements. Results Of 31,483 patients analyzed from the database, 16,726 patients (53.1%) were tested for ALK rearrangements. ALK testing rates were 66.9% and 18.5% in patients with nonsquamous and squamous histology, respectively. Average ALK testing rates increased over time from 32.4% in 2011 to 62.1% in 2016. Fluorescent in situ hybridization was the most common ALK testing method. Agreement between fluorescent in situ hybridization and other assays ranged from 94.1% to 97.9%. Median (interquartile range) time from laboratory receipt of sample to first ALK test result was 7 (7) days; median time from advanced diagnosis to first ALK test result was 25 (29) days. Patients who were older, male, had a history of smoking, lived in non-Western US regions, and who had recurrent disease or squamous histology were less likely to be tested for ALK. Patients with Medicaid and Medicare insurance were less likely to be tested than patients with commercial insurance. Overall, 21.5% of patients initiated therapy (20.4% chemotherapy) before receiving test results. Conclusion ALK testing rates have increased over time. However, certain subgroups of patients are less likely to be tested, suggesting that additional education on molecular testing is warranted.
Real-Time Measurement of Xenon Concentration in a Binary Gas Mixture Using a Modified Ultrasonic Time-of-Flight Anesthesia Gas Flowmeter: A Technical Feasibility Study
Authors: Williams David J. , Hallewell Gregory D. , Chakkarapani Ela , Dingley John 
Published: October 2018

BACKGROUND:Xenon (Xe) is an anesthetic gas licensed for use in some countries. Fractional concentrations (%) of gases in a Xe:oxygen (O2) mixture are typically measured using a thermal conductivity meter and fuel cell, respectively. Speed of sound in such a binary gas mixture is related to fractional concentration, temperature, pressure, and molar masses of the component gases. We therefore performed a study to assess the feasibility of developing a novel single sterilizable device that uses ultrasound time-of-flight to measure both real-time flowmetry and fractional gas concentration of Xe in O2.METHODS:For the purposes of the feasibility study, we adapted an ultrasonic time-of-flight flowmeter from a conventional anesthetic machine to additionally measure real-time fractional concentration of Xe in O2. A total of 5095 readings of Xe % were taken in the range 5%–95%, and compared with simultaneous measurements from the gold standard of a commercially available thermal conductivity Xe analyzer.RESULTS:Ultrasonic measurements of Xe (%) showed agreement with thermal conductivity meter measurements, but there was marked discontinuity in the middle of the measurement range. Bland-Altman analysis (95% confidence interval in parentheses) yielded: mean difference (bias) 3.1% (2.9%–3.2%); lower 95% limit of agreement −4.6% (−4.8% to −4.4%); and upper 95% limit of agreement 10.8% (10.5%–11.0%).CONCLUSIONS:The adapted ultrasonic flowmeter estimated Xe (%), but the level of accuracy is insufficient for clinical use. With further work, it may be possible to develop a device to perform both flowmetry and binary gas concentration measurement to a clinically acceptable degree of accuracy.

Published: October 2018

Abstract
This work develops and conceptualizes a new theory, Post Traumatic Slave Master Syndrome, that is utilized to critically correlate historic patterns of lynching Black women to contemporary violent state (actor) responses to Black women’s resistance, specifically relating to the neo-lynching of Korryn Gaines and Sandra Bland. This work deviates from the tradition of analyzing the history and contemporary effects of racism and white supremacy, patriarchy, lynching, policing, and state-sponsored violence from the perspective of the effects upon the victim and instead critiques how white supremacy affects the perpetrator. This chapter contributes to ensuring that Black women resisters continue to #SayHerName.

Background Antidepressants for postnatal depression may not be acceptable to women and so many may seek alternative therapies. Aim To evaluate the effectiveness and safety of acupuncture for postnatal depression compared with antidepressant treatment. Methods A literature search was conducted in English, Chinese, Japanese and Korean databases. Details of the trials were extracted and analysed. Findings Of the 1592 studies reviewed, three met the inclusion criteria for quantitative analysis. Two studies reported no significant differences between acupuncture and fluoxetine for depression, while the third reported significant improvements. Conclusions Acupuncture in postpartum depression was at least as effective as fluoxetine hydrochloride, supporting the notion that acupuncture may be a safe and effective option.

Published: October 2018

During the last decades, several research groups have used bisphosphonates for local application to counteract secondary bone resorption after bone grafting, to improve implant fixation or to control bone resorption caused by bone morphogenetic proteins (BMPs). We focused on zoledronate (a bisphosphonate) due to its greater antiresorptive potential over other bisphosphonates. Recently, it has become obvious that the carrier is of importance to modulate the concentration and elution profile of the zoledronic acid locally. Incorporating one fifth of the recommended systemic dose of zoledronate with different apatite matrices and types of bone defects has been shown to enhance bone regeneration significantly in vivo. We expect the local delivery of zoledronate to overcome the limitations and side effects associated with systemic usage; however, we need to know more about the bioavailability and the biological effects. The local use of BMP-2 and zoledronate as a combination has a proven additional effect on bone regeneration. This review focuses primarily on the local use of zoledronate alone, or in combination with bone anabolic factors, in various preclinical models mimicking different orthopaedic conditions.

Background Hyperleukocytosis in childhood acute lymphoblastic leukemia (ALL) is an emergency in oncology. This condition showed high mortality and relapse rates, as well as low survival rate. The outcomes of this group of patients are not yet well studied.
Objective To evaluate the characteristics and outcomes of childhood acute lymphoblastic leukemia (ALL) with hyperleukocytosis.
Methods This was a retrospective cohort study. The patients were children less than 18 year of age who were diagnosed as ALL in Dr. Sardjito Hospital, Yogyakarta, from January 1st 2010 to November, 30th 2016. Event-free survival rate and overall survival rate were estimated for group of patients with the white blood cell (WBC) groups 50-200x109/L and >200x109/L using the Kaplan-Meier method.
Results There were 705 children diagnosed as ALL during the study period, 129 (18%) with hyperleukocytosis and 111 of them met the inclusion criteria, consisted of 76 children in a group of WBC 50-200 x 109/L and 35 children in a group of WBC >200 x 109/L. Presentation at diagnosis: median age were 7 years (range 1 month-18 years), male was 1.5 higher than female, 92% of cases with lymphoid infiltration, 5% with CNS involvement, 40% had bleeding tendency, and 10% had clinical tumor lysis syndrome (TLS). Median WBC was 122 (range 53.4-876) x 109/L; mean Hb was 8 (SD 3) g/dL; median platelet count was 30 (range 1-221) x 109/L. Immunophenotyping was done in 23 patients, 5/23 (8%) was T cell. The patients in lower WBC group showed lower death (26% vs. 34%, P=0,389), higher two-year event-free survival (EFS) 68% vs. 45%, P=0.003, and overall survival (77% vs. 68%, P= 0.16), compared to patients in higher WBC group. Univariate and multivariate Cox regression analyses revealed that none of the variables was a significant prognostic factor for 2 years EFS or overall survival.
Conclusion The group of children with ALL and hyperleukocytosis with lower WBC at diagnoses showed better outcomes than the higher WBC.

Increasing awareness of the rising global rates of multidrug-resistant tuberculosis (MDR-TB) has led to a concerted international effort to confront this disease. Nonetheless, despite cure rates >80% in some programs, MDR-TB patients tend to have chronic disease and require prolonged therapy.1-3 Little is known about the long-term results and follow-up of patients with MDR-TB, include the recurrence rate and chronic disability in patients who have recovered from TB.4
There are many side effects and adverse reactions to drugs can occur during MDR-TB treatment. These could be physical and or psychological, as well as reversible or irreversible. Treatment of MDR-TB requires a combination regimen, consists of second and third-line anti-tuberculosis drugs which more toxic than first-line drugs. Additionally, MDR-TB treatment requires a long duration of treatment (18-24 months) and causes discomfort in the patient.5 In a cohort of 60 patients treated for MDR-TB, the most common side effects included gastritis (100%), dermatological disorders (43%), and peripheral neuropathy (16.7).6 While in a cohort of 75 patients, the incidence of depression, anxiety, and psychosis for MDR-TB treatments was 13.3%, 12.0%, and 12.0%, respectively.7
Aggressive and effective management are needed so the patient can tolerate the treatment and remain adhere the treatment.8 Long-term follow-up is required for the rehabilitation of disorders due to psychosocial sequelae. As such, psychosocial support can be benefit pediatric MDR-TB patients.
Here, we present a case report on a two-year follow-up of a pubertal child with MDR-TB, focusing on medical aspects and her development.
Graduate and Undergraduate Faculty Collaboration Utilizing Peer Observation to Enhance Educational Opportunities for Students and Faculty: A Case Example
Authors: Barton Christopher E. , Williams Christi L. , Halle John S. , McGrew Lori 
Published: October 2018

While evidence supports the use of cadavers to facilitate the teaching and learning of human anatomy, cadaver-based teaching may not be present at the undergraduate level at many institutions due to limited laboratory access, financial constraints, and the lack of qualified faculty trained to teach in this type of setting. The following case example outlines a unique program designed to provide cadaver-based instruction to undergraduate students, while simultaneously training undergraduate faculty to teach in this setting through peer observational methods. More specifically, the following teaching collaboration was designed with the intent to achieve the following: 1) expose undergraduate anatomy students to cadaver-based learning; 2) provide education and training to undergraduate faculty so they are better qualified to teach human anatomy in the context of a cadaver laboratory; 3) provide graduate physical therapy students additional opportunities to dissect and reinforce their anatomy knowledge; and 4) demonstrate the value of interdisciplinary collaboration. Eighty-one undergraduate students were exposed to the cadaver laboratory for four educational sessions throughout the semester. Course evaluations revealed that 93% of the undergraduate students reported that their experiences in the cadaver laboratory served to enhance their learning, and 97% reported that the use of human cadavers should be continued in future courses. This interdisciplinary model allowed anatomy instruction to be expanded to previously unserved student groups as well as provided a mechanism for professional development of undergraduate anatomy faculty. This model may serve as a template to promote new program development to enhance faculty and student learning, while simultaneously encouraging interdisciplinary collaboration across the university.Keywords: interdisciplinary, peer observation, pedagogy, anatomy, cadaver
