RESUMO
Systemic administration of adeno-associated virus (AAV) vectors for spinal cord gene therapy has challenges including toxicity at high doses and pre-existing immunity that reduces efficacy. Intrathecal (IT) delivery of AAV vectors into cerebral spinal fluid can avoid many issues, although distribution of the vector throughout the spinal cord is limited, and vector entry to the periphery sometimes initiates hepatotoxicity. Here we performed biopanning in non-human primates (NHPs) with an IT injected AAV9 peptide display library. We identified top candidates by sequencing inserts of AAV DNA isolated from whole tissue, nuclei, or nuclei from transgene-expressing cells. These barcoded candidates were pooled with AAV9 and compared for biodistribution and transgene expression in spinal cord and liver of IT injected NHPs. Most candidates displayed increased retention in spinal cord compared with AAV9. Greater spread from the lumbar to the thoracic and cervical regions was observed for several capsids. Furthermore, several capsids displayed decreased biodistribution to the liver compared with AAV9, providing a high on-target/low off-target biodistribution. Finally, we tested top candidates in human spinal cord organoids and found them to outperform AAV9 in efficiency of transgene expression in neurons and astrocytes. These capsids have potential to serve as leading-edge delivery vehicles for spinal cord-directed gene therapies.

PURPOSE: The demographic and radiological risk factors of subchondral insufficiency fractures of the knee (SIFK) continue to be a subject of debate. The purpose of this study was to associate patient-specific factors with SIFK in a large cohort of patients. METHODS: Inclusion criteria consisted of patients with SIFK as verified on magnetic resonance imaging (MRI). All radiographs and MRIs were reviewed to assess characteristics such as meniscus tear presence and type, subchondral oedema presence and location, location of SIFK, mechanical limb alignment, osteoarthritis as assessed by Kellgren-Lawrence grade and ligamentous injury. A total of 253 patients (253 knees) were included, with 171 being female. The average body mass index (BMI) was 32.1 ± 7.0 kg/m2. RESULTS: SIFK was more common in patients with medial meniscus tears (77.1%, 195/253) rather than tears of the lateral meniscus (14.6%, 37/253) (p < 0.001). Medial meniscus root and radial tears of the posterior horn were present in 71.1% (180/253) of patients. Ninety-one percent (164/180) of medial meniscus posterior root and radial tears had an extrusion ≥3.0 mm. Eighty-one percent (119/147) of patients with SIFK on the medial femoral condyle and 86.8% (105/121) of patients with SIFK on the medial tibial plateau had a medial meniscus tear. Varus knees had a significantly increased rate of SIFK on the medial femoral condyle in comparison to valgus knees (p = 0.016). CONCLUSION: In this large cohort of patients with SIFK, there was a high association with medial meniscus root and radial tears of the posterior horn, meniscus extrusion ≥3.0 mm as well as higher age, female gender and higher BMI. Additionally, there was a particularly strong association of medial compartment SIFK with medial meniscus tears. As SIFK is frequently undiagnosed, identifying patient-specific demographic and radiological risk factors will help achieve a prompt diagnosis. LEVEL OF EVIDENCE: Level IV.
RESUMO
BACKGROUND: The use of antibiotic-impregnated cement during 2-stage revision arthroplasty for periprosthetic joint infection poses a risk of renal complications following spacer insertion. This systematic review aimed to investigate the rate of acute kidney injury (AKI) following antibiotic-loaded spacer insertion and to identify risk factors associated with this complication. METHODS: A systematic review was performed using PubMed, Cochrane Central, and Scopus databases. All clinical studies that documented renal complications following antibiotic-loaded spacer insertion for periprosthetic knee (total knee arthroplasty [TKA]) or hip (total hip arthroplasty [THA]) infection were included. Articles that combined THA and TKA outcomes were also included and labeled "THA + TKA." Descriptive statistics were analyzed when data were available. RESULTS: There were 24 studies (9 THA, 7 TKA, 8 THA + TKA) included. The mean incidences of spacer-related AKI across THA, TKA, and THA + TKA cohorts were 4.2 (range, 0 to 10%), 14 (range, 0 to 19%), and 27% (range, 0 to 35%), respectively. The most common patient-related risk factors for AKI were underlying chronic kidney disease or high baseline creatinine, low preoperative hemoglobin, and blood transfusion requirement. Spacer-related risk factors included high antibiotic dosage (>3.6 g/cement batch) and antibiotic type. While most recovered without complication, select patients required hemodialysis for acute management (2 THA, 18 THA + TKA) and/or developed chronic kidney disease (8 TKA, 8 THA). CONCLUSION: The rate of AKI following spacer insertion was high and likely under-reported in the literature. Surgeons should be cognizant of this devastating complication and should closely monitor at-risk patients for AKI following antibiotic-loaded spacer insertion.

BACKGROUND: Justice-involved Veterans experience notable risk for psychosocial stressors (e.g., homelessness) and psychiatric multimorbidity, which can result in complex clinical presentations. However, research examining how such factors coalesce to impact risk for suicide remains limited. METHODS: We conducted a latent class analysis of 180,454 Veterans accessing Veterans Health Administration (VHA) justice-related services from 2005 to 2018. RESULTS: A four-model class membership solution was identified. Among these classes, risk for suicide was highest among Veterans with greater psychiatric burden, with risk most notable among those with high VA service use. Veterans seeking healthcare primarily focused on substance use disorders or with low psychiatric burden and service use had a lower risk for suicide. CONCLUSIONS: Psychiatric multimorbidity is salient as it relates to suicide among Veterans accessing VHA justice-related services. Further evaluation of existing VHA services for this population and methods of augmenting and enhancing care for justice-involved Veterans with histories of co-occurring psychiatric conditions may be beneficial in facilitating suicide prevention efforts.

BACKGROUND: The use of preoperative patient-reported outcome measure (PROM) thresholds for patient selection in arthroplasty care has been questioned recently. This study aimed to identify factors affecting achievement of the minimal clinically important difference (MCID) and patient acceptable symptom state (PASS) after total knee arthroplasty (TKA) and determine the overlap between the two outcomes. METHODS: We identified 1,239 primary, unilateral TKAs performed at a single institution in 2015-2019. PROMs including the Knee injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS-JR) and 12-item Short Form Health Survey (SF-12) were collected preoperatively and 1-year postoperatively. The likelihood of attaining PASS as per attainment of MCID was assessed. A multivariable regression was used to identify predictors of MCID and PASS. RESULTS: In total, 71.3% achieved MCID and 75.5% achieved PASS for KOOS-JR. Only 7.7% achieved MCID but not PASS, whereas almost twice this number did not achieve MCID but did achieve PASS (11.9%). Poorer preoperative KOOS-JR (OR 0.925), better SF-12 physical (OR 1.025), and mental (OR 1.027) were associated with MCID attainment. In contrast, better preoperative KOOS-JR (OR 1.030) and SF-12 mental (OR 1.025) were associated with PASS attainment. Age, gender, race, ethnicity, body mass index, Charlson index, American Society of Anesthesiologists classification, and smoking status were not significant predictors. CONCLUSION: Preoperative PROMs were associated with achieving MCID and PASS after TKA, albeit some positively and some negatively. In the era of value-based care, clinicians should not only strive to help patients "feel better" but also ensure that patients "feel good" after surgery. This study does not support the use of PROMs in prioritizing access to care.

BACKGROUND: Although studies have compared the claims costs of simultaneous and staged bilateral total hip arthroplasty (THA) and total knee arthroplasty (TKA), whether a simultaneous procedure is cost-effective to the facility remains unknown. This study aimed to compare facility costs and perioperative outcomes of simultaneous vs staged bilateral THA and TKA. METHODS: We reviewed a consecutive series of 560 bilateral THA (170 staged and 220 simultaneous) and 777 bilateral TKA (163 staged and 451 simultaneous). Itemized facility costs were calculated using time-driven activity-based costing. Ninety-day outcomes were compared. Margin was standardized to unadjusted Medicare Diagnosis Related Group payments (simultaneous, $18,523; staged, $22,386). Multivariate regression was used to determine the independent association between costs/clinical outcomes and treatment strategy (staged vs simultaneous). RESULTS: Simultaneous bilateral patients had significantly lower personnel, supply, and total facility costs compared with staged patients with no difference in 90-day complications between the groups. Multivariate analyses showed that overall facility costs were $1,210 lower in simultaneous bilateral THA (P < .001) and $704 lower in TKA (P < .001). Despite lower costs, margin for the facility was lower in the simultaneous group ($6,569 vs $9,225 for THA; $6,718 vs $10,067 for TKA; P < .001). CONCLUSION: Simultaneous bilateral TKA and THA had lower facility costs than staged procedures because of savings associated with a single hospitalization. With the increased Medicare reimbursement for 2 unilateral procedures, however, margin was higher for staged procedures. In the era of value-based care, policymakers should not penalize facilities for performing cost-effective simultaneous bilateral arthroplasty in appropriately selected patients.

BACKGROUND: Diabetic ketoacidosis causes a significant number of hospitalisations worldwide, with rates tending to increase with remoteness and socioeconomic disadvantage. Our study aimed to explore healthcare professionals' perceptions of factors affecting presentation of people with type 1 diabetes in a low socioeconomic area of Queensland, Australia. METHODS: This was a qualitative study. Individual semi-structured face-to-face or telephone interviews were completed with patients with type 1 diabetes who had presented in diabetic ketoacidosis, and healthcare professionals who have experience in related care. Data were analysed using Gibbs's framework of thematic analysis. RESULTS: Four patients with type 1 diabetes and 18 healthcare professionals were interviewed. Restricted access was identified as a factor contributing to diabetic ketoacidosis and delayed presentation, with ketone testing supplies, continuous glucose monitoring technology and transport considered barriers. Many of these factors were arguably preventable. Opportunities to improve the care available to patients with type 1 diabetes were detailed, with particularly strong support for dedicated out of hours telephone help lines for adults with type 1 diabetes. CONCLUSIONS: Gaps in support for patient self-care to avoid diabetic ketoacidosis presentations and prevent late presentation of diabetic ketoacidosis revealed by this study require service reconfiguration to support care delivery. Until change is made, people with type 1 diabetes will continue to make both avoidable and delayed, acutely unwell, presentations to Emergency Departments.

Moral Reconation Therapy (MRT), an evidence-based intervention to reduce risk for criminal recidivism among justice-involved adults, was developed and primarily tested in correctional settings. Therefore, a better understanding of the implementation potential of MRT within non-correctional settings is needed. To address this gap in the literature, we evaluated the adoption and sustainment of MRT in the US Veterans Health Administration (VHA) following a national training initiative in fiscal years 2016 and 2017. In February 2019, surveys with 66 of the 78 VHA facilities that participated in the training were used to estimate the prevalence of MRT adoption and sustainment, and qualitative interviews with key informants from 20 facilities were used to identify factors associated with sustainment of MRT groups. Of the 66 facilities surveyed, the majority reported adopting (n = 52; 79%) and sustaining their MRT group until the time of the survey (n = 38; 58%). MRT sustainment was facilitated by strong intra-facility (e.g., between veterans justice and behavioral health services) and inter-agency collaborations (e.g., between VHA and criminal justice system stakeholders), which provided a reliable referral source to MRT groups, external incentives for patient engagement, and sufficient staffing to maintain groups. Additional facilitators of MRT sustainment were adaptations to the content and delivery of MRT for patients and screening of referrals to the groups. The findings provide guidance to clinics and healthcare systems that are seeking to implement MRT with justice-involved patient populations, and inform development of implementation strategies to be formally tested in future trials.

Long non-coding RNA (lncRNA) biology is a rapidly growing area of study. Thousands of lncRNAs are implicated as key players in cellular pathways and cancer biology. However, the structure-function relationships of these novel biomolecules are not well understood. Recent structural studies suggest that lncRNAs contain modular structural domains, which play a crucial role in their function. Here, we hypothesized that such structural domains exist in lncTCF7, a conserved lncRNA implicated in the development and progression of several cancers. To understand the structure-function relationship of lncTCF7, we characterized its secondary structure using chemical probing methods. Our model revealed structural domains and conserved regions in lncTCF7. One of the modular domains identified here coincides with a known protein-interacting domain. The model reported herein is, to our knowledge, the first structural model of lncTCF7 and thus will serve to direct future studies that will provide fundamental insights into the function of this lncRNA.

Although there are now over 400 veterans treatment courts (VTCs) in the country, there have been few studies on participant outcomes in functional domains. Using national data on 7931 veterans in the Veterans Affairs (VA) Veterans Justice Outreach program across 115 VA sites who entered a VTC from 2011 to 2015, we examined the housing, employment, income, and criminal justice outcomes of VTC participants; and identified veteran characteristics predictive of outcomes. VTC participants spent an average of nearly a year in the program and 14% experienced a new incarceration. From program admission to exit, 10% more participants were in their own housing, 12% more were receiving VA benefits, but only 1% more were employed. Controlling for background characteristics, a history of incarceration predicted poor criminal justice, housing, and employment outcomes. Participants with property offenses or probation/parole violations and those with substance use disorders were more likely to experience a new incarceration. Participants with more mental health problems were more likely to be receiving VA benefits and less likely to be employed at program exit. Together, these findings highlight the importance of proper substance abuse treatment as well as employment services for VTC participants so that they can benefit from the diversion process.

Gaucher disease (GD) is caused by mutations in the GBA1 gene that encodes the lysosomal enzyme acid ß-glucosidase (GCase). Reduced GCase activity primarily leads to the accumulation of two substrates, glucosylceramide (GlcCer) and glucosylsphingosine (GlcSph). Current treatment options have not been shown to ameliorate the neurological pathology observed in the most severe forms of GD, clearly representing an unmet medical need. To better understand the relationship between GlcCer and GlcSph accumulation and ultimately their connection with the progression of neurological pathology, we developed LC-MS/MS methods to quantify GlcCer and GlcSph in mouse brain tissue. A significant challenge in developing these methods was the chromatographic separation of GlcCer and GlcSph from the far more abundant isobaric galactosyl epimers naturally occurring in white matter. After validation of both methods, we evaluated the levels of both substrates in five different GD mouse models, and found significant elevation of brain GlcSph in all five, while GlcCer was elevated in only one of the five models. In addition, we measured GlcCer and GlcSph levels in the brains of wild-type mice after administration of the GCase inhibitor conduritol ß-epoxide (CBE), as well as the nonlysosomal ß-glucosidase (GBA2) inhibitor N-butyldeoxygalactonojirimycin (NB-DGJ). Inhibition of GCase by CBE resulted in elevation of both sphingolipids; however, inhibition of GBA2 by NB-DGJ resulted in elevation of GlcCer only. Taken together, these data support the idea that GlcSph is a more selective and sensitive biomarker than GlcCer for neuronopathic GD in preclinical models.

STUDY OBJECTIVE: Peripheral intravenous catheters are the most common invasive device in health care yet have very high failure rates. We investigate whether the failure rate could be reduced by the addition of skin glue to standard peripheral intravenous catheter care. METHODS: We conducted a single-site, 2-arm, nonblinded, randomized, controlled trial of 380 peripheral intravenous catheters inserted into 360 adult patients. The standard care group received standard securement. The skin glue group received standard securement plus cyanoacrylate skin glue applied to the skin insertion site. The primary outcome was peripheral intravenous catheter failure at 48 hours, regardless of cause. Secondary outcomes were the individual modes of peripheral intravenous catheter failure: infection, phlebitis, occlusion, or dislodgement. RESULTS: Peripheral intravenous catheter failure was 10% lower (95% confidence interval -18% to -2%; P=.02) with skin glue (17%) than standard care (27%), and dislodgement was 7% lower (95% confidence interval -13% to 0%; P=.04). Phlebitis and occlusion were less with skin glue but were not statistically significant. There were no infections. CONCLUSION: This study supports the use of skin glue in addition to standard care to reduce peripheral intravenous catheter failure rates for adult emergency department patients admitted to the hospital.

This study used data from a phone survey inventory of US veterans' courts to provide descriptive information on the current status of their various elements. To identify which items were most predictive of a court's percentage of subjects terminated from their program, a linear regression was performed. The following were associated with higher rates of termination from the veterans' court (VC) program: (a) programs that offered phase progression based on measurable goals, (b) programs that conduct frequent drug and alcohol testing, and (c) programs for which sanctions are more severe for failing immediate goals (sobriety) versus long-term ones (completion of training). The following were associated with lower rates of termination from the VC program: (a) programs in which later phases permit less stringent testing, (b) programs utilizing behavioral contracts, (c) programs utilizing brief incarcerations. This inventory provides nationwide empirical data that may be used in the development of veterans' courts.

The cultural divide between US military and civilian institutions amplifies the consequences of military discharge status on public health and criminal justice systems in a manner that is invisible to a larger society. Prompt removal of problematic wounded warriors through retributive justice is more expedient than lengthy mental health treatment. Administrative and punitive discharges usually preclude Department of Veterans Affairs eligibility, posing a heavy public health burden. Moving upstream--through military rehabilitative justice addressing military offenders' mental health needs before discharge--will reduce the downstream consequences of civilian maladjustment and intergenerational transmission of mental illness. The public health community can play an illuminating role by gathering data about community effect and by advocating for policy change at Department of Veterans Affairs and community levels.

The hip capsule is the primary stabilizer of the hip joint. At the time of hip arthroscopy, the capsule is disrupted to obtain intra-articular access and proper joint visualization. With the number of patients undergoing primary and revision hip arthroscopy continuing to increase, it is not uncommon for surgeons to encounter patients with iatrogenic capsular deficiency from prior hip arthroscopy. In cases where substantial capsular defects beyond the scope of capsular repair are visualized, reconstruction may be required to obtain satisfactory closure and restore hip stability. We present a step-by-step workflow for efficient hip capsular reconstruction with rectus overlay while allowing for facile incorporation of other revision procedures such as labral repair and femoral osteochondroplasty.
RESUMO
Purpose: To determine the content posted by sports medicine orthopaedic surgeons on Instagram and Twitter and to evaluate the associated engagement. Methods: Data were collected from sports medicine orthopaedic surgeons' Instagram profiles and Twitter profiles between December 2020 and June 2022. The median number of total number of likes, comments, and retweets was calculated. The content of posts from both platforms was divided into the following categories: personal life, research, patient testimony, day in the life, pathway to becoming a physician, clinical cases, medical facts, and team coverage. Results: Data from 71 Instagram profiles and 39 Twitter profiles were used in this study. A total of 1,193 posts were identified on Instagram and 1,284 posts were identified on Twitter. The personal life category had the greatest number of posts on Instagram (303, 25.4%), whereas the medical facts category had the greatest number of posts on Twitter (251, 19.5%). Pathway to becoming a physician had the greatest median number of likes on both Instagram (97.5, range 48-2,467) and Twitter (19, range 0-50) and the greatest median number of comments on Instagram at 16 (range 1-203). The team coverage category on Instagram had the greatest percentage of likes per follower at 9.9%. A significantly greater percentage of orthopaedic surgeons posted about day in the life content, medical facts, and research on Twitter in comparison with Instagram. Instagram resulted in significantly more social media engagement than Twitter in all 8 categories (P < .05). Conclusions: Instagram resulted in significantly more social media engagement across all categories in comparison with Twitter with team coverage, personal life, and pathway to becoming a physician being the most popular categories. Clinical Relevance: The information learned in this study may help sports surgeons understand how they may best utilize social media to engage with others and enhance their clinical practice.
RESUMO
Background: Ulnar collateral ligament (UCL) reconstruction has been the standard surgical intervention for elite male athletes with UCL insufficiency. Recently, UCL repair and augmentation with an internal brace has been increasingly performed. Purpose: To evaluate the clinical and functional outcomes as well as return-to-sport rate after UCL repair in female athletes. Study Design: Case series; Level of evidence, 4. Methods: Included were 15 female athletes (mean age, 16.5 ± 3.5 years) who underwent UCL repair between 2011 and 2021 at a single institution. Data collected included age, sport played, competition level, symptom onset, previous surgeries, mechanism of injury, surgical intervention, and return to sport. Patients were contacted via phone at minimum 24-month follow-up, and postoperative outcomes were evaluated using the Mayo Elbow Performance Score (MEPS) and the Single Assessment Numeric Evaluation (SANE). Results: Of the 15 female athletes, there were 4 cheerleaders, 3 softball players, 2 volleyball players, 2 soccer players, 1 gymnast, 1 tennis player, 1 dancer, and 1 javelin thrower. Ten of the 15 athletes (67%) competed at the high school level, 4 (26%) at the collegiate level, and 1 patient (7%) was a recreational volleyball player. In all patients, there was an acute onset of symptoms after injury. Ten patients underwent UCL repair with an internal brace (67% of athletes), while 5 underwent standard UCL repair. The median MEPS for athletes with and without an internal brace was 100 (range, 80-100). There was no significant difference of MEPS (P = .826) or SANE scores (P = .189) between the patients who received an internal brace and those who did not. Thirteen of the 15 athletes (86.7%) returned to sport. Conclusion: The UCL injuries in the female athletes in this study were the result of acute trauma. Primary UCL repair, both with and without internal bracing, was an effective surgical treatment for returning these athletes to sport.
RESUMO
The purpose of this study was to identify trends in the use of functional outcome measures within orthopedic oncology. The search engine, PubMed, was reviewed for all articles over an 11-year period from 2011 to 2021 from five major journals that publish in the field of orthopedic oncology. The functional outcome measures used in the articles were recorded along with study date, study design, clinical topic/pathology, and level of evidence. Out of 5968 musculoskeletal tumor-focused articles reviewed, 293 (4.9%) included at least one outcome measure. A total of 28 different outcome tools were identified. The most popular were Musculoskeletal Tumor Society (MSTS) score (61.1%) and Toronto Extremity Salvage (TESS) score (14.0%), followed by 36-Item Short Form Survey (SF-36) (4.1%) and Patient-Reported Outcomes Measurement Information System (PROMIS) (3.8%). The use of MSTS scores decreased by 0.7% each year, whereas PROMIS increased by 1.2% each year. Seventy-four articles used more than one outcome measure. Of these 74 articles, 61 had the MSTS as one of the outcome measures. Orthopedic oncology utilizes functional outcome measures less commonly in comparison to other orthopedic subspecialties. However, this may be due in large part to orthopedic oncologists putting more emphasis on outcomes such as local recurrence, implant failure, and mortality. MSTS score is the most widely used functional outcome measure, but the utilization of PROMIS has increased recently, and could be the next step in evaluating outcomes in orthopedic oncology as it is patient-derived rather than physician-derived.

CASE: A 20-year-old woman presented with a unipolar, 1.8 × 1.8-cm osteochondral defect of the left acetabulum. Osteochondral allograft transplantation was performed using a medial tibial plateau allograft resulting in excellent clinical outcomes across 4 different outcome scores and maintenance of the joint space at 4.3 years postoperatively. CONCLUSION: Although previous literature has demonstrated long-term clinical success of osteochondral allograft transplantation in knee, excellent clinical outcomes can also be obtained in the hip. Thus, osteochondral allograft transplantation may be a viable treatment option for adolescents and young adults with concomitant cartilage and subchondral bone hip defects.

The integrity of the posterior meniscus root attachment is vital for the preservation of knee joint biomechanics. Meniscus root tears treated nonoperatively or with meniscectomy lead to poor functional outcomes and progressive knee degeneration. Repair returns knee biomechanics back to the intact state and has an established record of positive mid-term to long-term results. Although transtibial pullout repair has been the gold standard, innovation is needed to overcome the limitations inherent to traditional approaches. The latest generation of transtibial pullout repair devices is adjustable, permits suture anchor placement directly into the root footprint, and has demonstrated encouraging early results in biomechanical analysis. This Technical Note describes an arthroscopic technique for medial meniscus posterior root repair that uses a knotless adjustable implant (SutureLoc; Arthrex) for aperture fixation via a transtibial approach with intratunnel soft anchor direct fixation and rip-stop suture configuration.
